AEROSOL GENERATION APPARATUS

Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to Chinese Patent Application No. CN 202411959740.8, filed with China National Intellectual Property Administration on Dec. 26, 2024 and entitled “AEROSOL GENERATION DEVICE”, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

This application relates to the field of aerosol generation technologies, and in particular, to an aerosol generation device.

BACKGROUND

An aerosol generation device is a device that can atomize an aerosol generation substrate to generate an aerosol. In some exemplary existing technologies, there is an aerosol generation device, including an atomizer, a power supply assembly, an operation switch, and an air adjustment assembly. The operation switch is configured to set a plurality of work modes of the power supply assembly. The power supply assembly provides different power for an atomization assembly in different work modes. The air adjustment assembly is configured to adjust an air inlet amount by which outside air that enters the atomization assembly. A user can operate the air adjustment assembly to change an air inlet area of an airflow channel, so as to adjust inhalation resistance.

However, a heating power of the atomization assembly needs to match the air inlet amount. If the heating power is large, but the air inlet amount is small, core burning may occur in the atomization assembly. If the heating power is small, but the air inlet amount is large, a poor puff taste may be caused. However, in the existing aerosol generation device, the operation switch and the air adjustment assembly are independent of each other, and the user needs to separately operate the operation switch and the air adjustment assembly. As a result, a case in which the heating power of the atomization assembly does not match the air inlet amount is likely to occur, resulting in poor use experience for the user.

SUMMARY

An objective of this application is to provide an aerosol generation device including an operation assembly. When the operation assembly is operated, a work mode of a power supply can be switched and a ventilation area of an air inlet can be adjusted.

At least one embodiment of this application provides an aerosol generation device. The aerosol generation device includes:

• • an inhalation port and an air inlet;
  • an atomization assembly, including a storage cavity configured to store an aerosol generation substrate and an atomization element configured to atomize the aerosol generation substrate to generate an aerosol;
  • an airflow channel, constructed between the air inlet and the inhalation port, and configured to provide, between the air inlet and the inhalation port, an airflow path passing through the atomization element;
  • a power supply assembly, including a power supply, where a plurality of work modes are set for the power supply, and the power supply is configured to provide different electric power for the atomization element in different work modes; and
  • an operation assembly, configured to be operable by a user to switch a work mode of the power supply and synchronously change a ventilation area of the air inlet.

In an example, the aerosol generation device further includes an airflow detector configured to detect a puff action. The work mode includes an adaptive mode and a constant mode. The power supply is configured to provide a constant electric power for the atomization element in the constant mode, and provide, for the atomization element, an electric power that changes in association with a puff force in the adaptive mode. The electric power provided for the atomization element in the constant mode is greater than a maximum value of the electric power provided for the atomization element in the adaptive mode.

The operation assembly is configured to increase the ventilation area of the air inlet when the power supply is switched from the adaptive mode to the constant mode.

In an example, the operation assembly includes a first operation member and a second operation member. The power supply assembly further includes a controller. The controller is configured to control the power supply to enter the adaptive mode in response to an operation of the first operation member, and control the power supply to enter the constant mode in response to an operation of the second operation member.

In an example, the air inlet includes at least one main air inlet and an auxiliary air inlet. When the work mode of the power supply is the adaptive mode, the auxiliary air inlet is closed and the at least one main air inlet is open. When the work mode of the power supply is the constant mode, the auxiliary air inlet and the at least one main air inlet are both open.

In an example, the adaptive mode includes a first adaptive mode and a second adaptive mode. The power supply is configured to provide a first range power for the atomization assembly in the first adaptive mode, and provide a second range power for the atomization assembly in the second adaptive mode. A smallest power in the second range power is greater than a largest power in the first range power.

The operation assembly includes a first operation member. The first operation member is configured to switch a type of the adaptive mode, and to adjust the air inlet to enable the air inlet to have a first ventilation area in the first adaptive mode and have a second ventilation area in the second adaptive mode. The first ventilation area is smaller than the second ventilation area.

In an example, the aerosol generation device includes a first switch element. The operation assembly includes a first operation member. At least a part of the first switch element is disposed in linkage with the first operation member. Alternatively, the first switch element is configured to sense a position of the first operation member.

The first operation member is configured to be movable between a first position and a second position. The power supply is in a first adaptive mode when the first operation member is located at the first position, and is in a second adaptive mode when the first operation member is located at the second position.

In an example, the air inlet includes a main air inlet provided on the first operation member.

The main air inlet comprises a plurality of main air inlets. A quantity of the main air inlets that are open when the first operation member is located at the first position is less than a quantity of the main air inlets that are open when the first operation member is located at the second position.

Alternatively, the main air inlet includes a first air inlet and a second air inlet. A ventilation area of the second air inlet is larger than a ventilation area of the first air inlet. The first air inlet is open and the second air inlet is closed when the first operation member is located at the first position. The second air inlet is open when the first operation member is located at the second position.

In an example, the first operation member is configured to be further movable to a third position. The main air inlets are all closed when the first operation member is located at the third position.

In an example, the aerosol generation device includes an auxiliary air inlet assembly. The auxiliary air inlet assembly is configured to be open in the constant mode, to enable outside air to enter the airflow channel through the auxiliary air inlet assembly, and is configured to be closed in the adaptive mode.

In an example, the aerosol generation device includes a second switch element, and the operation assembly includes a second operation member.

The second operation member is configured to be movable between a fourth position and a fifth position. When the second operation member is located at the fifth position, the second switch element is triggered to switch the power supply from a current adaptive mode to the constant mode. When the second operation member returns to the fourth position, the power supply is switched from the constant mode back to a previous adaptive mode.

In an example, the second switch element includes a normally-open pressure switch, and the normally-open pressure switch is configured to be triggered when being pressed.

The second operation member is configured to be disposed spaced away from the normally-open pressure switch when the second operation member is located at the fourth position, and to press against the normally-open pressure switch when the second operation member is located at the fifth position.

In an example, the aerosol generation device further includes a first return member. The first return member acts on the second operation member to provide an action force, to enable the second operation member to automatically return from the fifth position to the fourth position.

In an example, the second operation member is configured to press against the auxiliary air inlet assembly when the second operation member is located at the fifth position, to open the auxiliary air inlet assembly.

In an example, the auxiliary air inlet assembly includes a piston and an air inlet member. The air inlet includes an auxiliary air inlet disposed on the air inlet member. The piston blocks the auxiliary air inlet. The second operation member is configured to drive the piston to open the auxiliary air inlet when the second operation member moves from the fourth position to the fifth position.

In an example, the auxiliary air inlet assembly further includes a second return member. The piston includes a sealing portion. The second return member is connected to the air inlet member and the piston, to enable the sealing portion to automatically restore to block the auxiliary air inlet when the second operation member returns to the fourth position.

In an example, the piston further includes a driving portion connected to the sealing portion. A cavity is provided inside the air inlet member. An air outlet hole communicating with the fluid channel is further provided on the air inlet member. The sealing portion is movably disposed in the cavity. The driving portion passes through the auxiliary air inlet to be located outside the air inlet member, to be pressed by the second operation member.

In an example, the aerosol generation device further includes a housing. The atomization assembly and the power supply assembly are both disposed inside the housing. The second operation member is disposed on a side surface of the housing. The second operation member is configured to be pressed by the user to move from the fourth position to the fifth position.

In an example, a total length of the aerosol generation device along an axial direction is L1. A length of the second operation member along the axial direction is L2. L2≥L1/2.

In an example, the aerosol generation device further includes a connection member. The connection member includes a second connection portion and a first connection portion that extends along the axial direction. The first connection portion and the second connection portion are spaced away from each other in a direction perpendicular to the axial direction.

The first connection portion is connected to the second operation member. The second connection portion is connected to the housing. A length L3 of the first connection portion along the axial direction satisfies: L3/L2≥½.

In an example, the atomization assembly includes a first air guide tube. The atomization element includes a first atomization element including a first heating element and a second heating element. The first air guide tube is disposed corresponding to the first atomization element, to guide, to the inhalation port, an aerosol generated by the first atomization element through atomization. The power supply assembly is configured to provide an electric power for only one of the first heating element and the second heating element or alternately provide an electric power for the first heating element and the second heating element in the adaptive mode, and provide electric power for both the first heating element and the second heating element in the constant mode.

In an example, the atomization assembly further includes a second air guide tube independent of the first air guide tube. The atomization element includes a second atomization element including a third heating element and a fourth heating element. The second air guide tube is disposed corresponding to the second atomization element, to guide, to the inhalation port, an aerosol generated by the second atomization element through atomization. The power supply is configured to provide an electric power for only one of the third heating element and the fourth heating element or alternately provide an electric power for the third heating element and the fourth heating element in the adaptive mode, and provide electric power for both the third heating element and the fourth heating element in the constant mode.

In the aerosol generation device provided in the foregoing embodiment, the power supply has a plurality of work modes, and the power supply provides different electric power for the atomization assembly in different work modes. When the operation assembly is operated, the work mode of the power supply can be switched and the ventilation area of the air inlet can be changed. This not only helps the user to more easily use the aerosol generation device, but also enables the power supply to match an output power of the atomization assembly and the ventilation area of the air inlet, so that use experience of the user can be improved.

The aerosol generation substrate may include both the nicotine and the flavoring agent. The aerosol generation substrate may simultaneously include a plurality of flavoring agents.

In some embodiments, the atomization assembly 2 includes one or more atomizers. The atomizers each include a storage cavity 21 configured to store the aerosol generation substrate and an atomization element 22 configured to atomize the aerosol generation substrate to generate the aerosol. In the embodiment shown in FIG. 1, the atomization assembly 2 includes only one atomizer.

In some embodiments, the aerosol generation substrate includes a liquid substrate. Based on this, the atomization element 22 may include a liquid absorbing element and a heating element, and the heating element is disposed on the liquid absorbing element. The liquid absorbing element may be a porous body, and is configured to guide the liquid substrate to an atomization range of the heating element. The heating element is configured to heat and atomize the liquid substrate, so as to generate the aerosol. The porous body may be a fiber, for example, a cotton fiber, a polypropylene fiber, a polyester fiber, or a nylon fiber. The porous body may be porous ceramic or porous metal. A structure and components of the porous body are not limited in this application.

In some embodiments, refer to FIG. 1, the atomizer further includes a liquid storage element 23. The liquid storage element 23 has a large quantity of pores and can adsorb a large quantity of liquid substrates. The liquid storage element 23 is disposed in the storage cavity 21, and at least a part of the liquid substrate stored in the storage cavity 21 is maintained in the liquid storage element 23, to prevent the liquid substrate from leaking from the storage cavity 21.

The liquid storage element 23 includes, but is not limited to, one of the following materials: a cotton fiber, a polypropylene fiber, a polyester fiber, a nylon fiber, a porous ceramic material, a polymer fiber, or various combinations of the foregoing materials.

In some embodiments, refer to FIG. 1 and FIG. 11, the atomizer further includes a first air guide tube 241. The atomization element 22 includes a first atomization element 221. The first air guide tube 241 is in fluid communication with the first atomization element 221. The first air guide tube 241 can export, out of the atomizer, the aerosol generated when the first atomization element 221 atomizes the aerosol generation substrate. The first air guide tube 241 may include a tubular structure extending along an axial direction.

Further, the first atomization element 221 includes a first heating element 2211 and a second heating element 2212. Both the first heating element 2211 and the second heating element 2212 are configured to heat the aerosol generation substrate, so that the aerosol generation substrate is atomized to generate the aerosol.

The first heating element 2211 and the second heating element 2212 may be arranged along an airflow direction, or the first heating element 2211 and the second heating element 2212 may be arranged along the axial direction X. The first heating element 2211 and the second heating element 2212 may not overlap in a radial direction Y. The radial direction Y is a direction perpendicular to the axial direction X, or a direction perpendicular to a central axis of the first air guide tube 241.

The liquid absorbing element includes a first liquid absorbing element. The first liquid absorbing element may have a large length in the axial direction, so that the first heating element 2211 and the second heating element 2212 that are arranged along the airflow direction can be disposed on a same first liquid absorbing element. Certainly, there may be two first liquid absorbing elements, and the two first liquid absorbing elements may be arranged along the airflow direction, or the two first liquid absorbing elements may be arranged along the axial direction X, so that the first heating element 2211 and the second heating element 2212 may be respectively disposed on the two liquid absorbing elements.

The power supply assembly 4 may independently provide electric power for the first heating element 2211 and the second heating element 2212, so that the first heating element 2211 and the second heating element 2212 can independently generate heat, to atomize the aerosol generation substrate. For example, the power supply assembly 4 may asynchronously provide the electric power for the first heating element 2211 and the second heating element 2212, so that the first heating element 2211 and the second heating element 2212 heat the aerosol generation substrate in different time periods. Alternatively, the power supply assembly 4 may alternately provide the electric power for the first heating element 2211 and the second heating element 2212, so that the first heating element 2211 and the second heating element 2212 heat the aerosol generation substrate in turn. Certainly, the power supply assembly 4 may alternatively provide the electric power for the first heating element 2211 and the second heating element 2212 simultaneously, so that the first heating element 2211 and the second heating element 2212 heat the aerosol generation substrate simultaneously.

In some embodiments, the atomizer further includes a second air guide tube 242. The atomization element 22 includes a second atomization element 222. The second air guide tube 242 is in fluid communication with the second atomization element 222. The second air guide tube 242 can export, out of the atomizer, the aerosol generated when the second atomization element 222 atomizes the aerosol generation substrate. The second air guide tube 242 may include a tubular structure extending along the axial direction. The second air guide tube 242 may be disposed in parallel with the first air guide tube 241. The first atomization element 221 and the second atomization element 222 may atomize an aerosol generation substrate stored in the same storage cavity 21.

Further, the second atomization element 222 includes a third heating element 2221 and a fourth heating element 2222. Both the third heating element 2221 and the fourth heating element 2222 are configured to heat the aerosol generation substrate, so that the aerosol generation substrate is atomized to generate the aerosol.

The third heating element 2221 and the fourth heating element 2222 may be arranged along the airflow direction, or the third heating element 2221 and the fourth heating element 2222 may be arranged along the axial direction X. The third heating element 2221 and the fourth heating element 2222 may not overlap in the radial direction Y.

The liquid absorbing element further includes a second liquid absorbing element that is independent of the first liquid absorbing element. The second liquid absorbing element may have a large length in the axial direction, so that the third heating element 2221 and the fourth heating element 2222 that are arranged along the airflow direction can be disposed on the same second liquid absorbing element. Certainly, there may be two second liquid absorbing elements, and the two second liquid absorbing elements may be arranged along the airflow direction, or the two second liquid absorbing elements may be arranged along the axial direction, so that the third heating element 2221 and the fourth heating element 2222 may be respectively disposed on the two second liquid absorbing elements.

The power supply assembly 4 may independently provide electric power for the third heating element 2221 and the fourth heating element 2222, so that the third heating element 2221 and the fourth heating element 2222 can independently generate heat, to atomize the aerosol generation substrate. For example, the power supply assembly 4 may asynchronously provide the electric power for the third heating element 2221 and the fourth heating element 2222, so that the third heating element 2221 and the fourth heating element 2222 heat the aerosol generation substrate in different time periods. Alternatively, the power supply assembly 4 may alternately provide the electric power for the third heating element 2221 and the fourth heating element 2222, so that the third heating element 2221 and the fourth heating element 2222 heat the aerosol generation substrate in turn. Certainly, the power supply assembly 4 may alternatively provide the electric power for the third heating element 2221 and the fourth heating element 2222 simultaneously, so that the third heating element 2221 and the fourth heating element 2222 heat the aerosol generation substrate simultaneously.

In some embodiments, the power supply assembly 4 includes a power supply 41. The power supply 41 may include any suitable battery. For example, the power supply 41 may include a lithium battery. The power supply 41 is configured to provide electric power for the atomization assembly 2.

A plurality of work modes may be set for the power supply 41. In different work modes, the power supply 41 outputs different electric power. In addition, in different work modes, the power supply 41 provides different electric power for the atomization assembly 2. For example, in one work mode, the power supply 41 provides an electric power for only one of the first atomization element 221 and the second atomization element 222. In another work mode, the power supply 41 provides electric power for both the first atomization element 221 and the second atomization element 222. Alternatively, for example, in one work mode, the power supply 41 provides electric power for only the first heating element 2211 in the first atomization element 221 and the third heating element 2221 in the second atomization element 222. In another work mode, the power supply 41 simultaneously provides electric power for the first heating element 2211, the second heating element 2212, the third heating element 2221, and the fourth heating element 2222. Alternatively, for example, in one work mode, the power supply 41 alternately provides an electric power for the first heating element 2211 and the second heating element 2212, and/or alternately provides an electric power for the third heating element 2221 and the fourth heating element 2222. Alternatively, for example, an electric power provided by the power supply 41 for the atomization assembly 2 in one work mode is greater than an electric power provided for the atomization assembly 2 in another work mode.

In some embodiments, refer to FIG. 1 and FIG. 2, the aerosol generation device 100 further includes an operation assembly 5. The operation assembly 5 may be operated by the user to switch a work mode of the power supply 41, so that the power supply 41 can be switched from one work mode to another work mode. In addition, when being operated by the user to switch the work mode of the power supply 41, the operation assembly 5 changes the ventilation area of the air inlet. Therefore, when the operation assembly 5 is operated, the work mode of the power supply 41 and the ventilation area of the air inlet can be synchronously changed, so that different work modes of the power supply 41 are in one-to-one correspondence with different ventilation areas of the air inlet. Therefore, the ventilation area of the air inlet can match an output power of the power supply 41 before delivery, so that, when the work mode of the power supply 41 is switched, the ventilation area of the air inlet matches a power outputted by the power supply 41 to the atomization assembly 2, to ensure that the atomization assembly 2 can work normally and generate an aerosol with a good mouth feel.

It may be understood that a larger ventilation area of the air inlet indicates smaller inhalation resistance, and outside air enters the aerosol generation device 100 at a larger airflow rate in unit time under the same puff force.

In some embodiments, the aerosol generation device 100 further includes an airflow detector (not shown in the figure) configured to detect a puff action. The airflow detector may be in fluid communication with the fluid channel 3, so that the airflow detector can determine, based on an airflow speed, an airflow direction, and/or an air pressure in the airflow channel 3, whether the aerosol generation device 100 is puffed. The power supply assembly 4 may provide an electric power for the atomization assembly 2 when the airflow detector detects the puff action.

Further, the airflow detector may further determine a force of a puff by detecting the airflow speed, the air pressure, an airflow acceleration, an acceleration of a change of the air pressure, duration by which a speed of the airflow exceeds a detection threshold, duration by which the air pressure of the airflow exceeds a detection threshold, and/or the like.

In some embodiments, the work mode of the power supply 41 may include an adaptive mode and a constant mode. The power supply 41 is configured to provide a constant electric power for the atomization assembly 2 in the constant mode, and provide, for the atomization assembly 2, an electric power that changes in association with a puff force in the adaptive mode.

In the adaptive mode, the electric power provided by the power supply 41 for the atomization assembly 2 may be in positive correlation with the current puff force; in other words, a larger puff force indicates a larger electric power provided by the power supply 41 for the atomization assembly 2. In the constant mode, the power supply 41 provides the constant electric power for the atomization assembly 2, and the electric power provided by the power supply 41 for the atomization assembly 2 does not change with a change of the puff force.

Further, the electric power provided by the power supply 41 for the atomization assembly 2 in the constant mode is greater than a maximum value of the electric power provided for the atomization assembly 2 in the adaptive mode, so that an amount of the aerosol generated by the atomization assembly 2 in the constant mode is greater than an amount of the aerosol generated by the atomization assembly 2 in the adaptive mode. Therefore, when the adaptive mode cannot satisfy a current puff requirement of the user, the user may select to switch the work mode of the power supply 41 to the constant mode.

The user may switch the work mode of the power supply 41 by operating the operation assembly 5, so that the work mode of the power supply 41 is switched from the adaptive mode to the constant mode, or from the constant mode to the adaptive mode, or from an adaptive mode to another adaptive mode. Certainly, the work mode of the power supply 41 may alternatively be switched from a constant mode to another constant mode by operating the operation assembly 5.

In some embodiments, when the current work mode of the power supply 41 is switched from the adaptive mode to the constant mode, the ventilation area of the air inlet is increased.

Further, the power supply 41 includes a plurality of adaptive modes. When any one of the adaptive modes is switched to the constant mode, the total ventilation area of the air inlet is increased.

For example, the adaptive mode includes a first adaptive mode and a second adaptive mode. A ventilation area S2 of the air inlet in the second adaptive mode is greater than a ventilation area S1 in the first adaptive mode, that is, S1<S2. When the current work mode of the power supply 41 is switched from the first adaptive mode to the constant mode, the ventilation area of the air inlet is increased, and an increasing ventilation area is ΔS1. Therefore, the total ventilation area changes to S3, and S3=S1+ΔS1. When the current work mode of the power supply 41 is switched from the second adaptive mode to the constant mode, the ventilation area of the air inlet is increased, and an increasing ventilation area is ΔS2. The total ventilation area changes to S4, and S4=S2+ΔS2.

ΔS1 may be equal to ΔS2, so that S3<S4. Therefore, the air inlet may have different total ventilation areas when the power supply 41 is switched from the first adaptive mode to the constant mode and switched from the second adaptive mode to the constant mode.

In addition/alternatively, S2 may be greater than or equal to S3. Therefore, when the work mode is switched from the first adaptive mode and the second adaptive mode to the constant mode, the ventilation area of the air inlet increases. However, the total ventilation area of the air inlet when the first adaptive mode is switched to the constant mode may be less than or equal to the total ventilation area of the air inlet in the second adaptive mode.

Certainly, S3 may alternatively be greater than S2.

In some embodiments, the ventilation area of the air inlet in the second adaptive mode is greater than the ventilation area in the first adaptive mode. In addition, the power supply 41 provides a first range power for the atomization assembly 2 in the first adaptive mode, and provides a second range power for the atomization assembly 2 in the second adaptive mode. The smallest power in the second range power is greater than the largest power in the first range power.

An electric power provided by the power supply 41 for the atomization assembly 2 after the power supply 41 is switched from the first adaptive mode to the constant mode may be equal to an electric power provided for the atomization assembly 2 after the power supply 41 is switched from the second adaptive mode to the constant mode. Alternatively, after the power supply 41 is switched from any work mode other than the constant mode to the constant mode, the power supply 41 provides a same electric power for the atomization assembly 2 in the constant mode.

Further, the total ventilation area of the air inlet in the constant mode is greater than the total ventilation area of the air inlet in any adaptive mode. Alternatively, the total ventilation area of the air inlet when the first adaptive mode is switched to the constant mode may be less than or equal to the total ventilation area of the air inlet in the second adaptive mode. Alternatively, when the power supply 41 is switched from any adaptive mode to the constant mode, the ventilation area of the air inlet increases.

In some embodiments, refer to FIG. 1 and FIG. 2, the air inlet includes at least one main air inlet 511. The operation assembly 5 includes a first operation member 51. The first operation member 51 is configured to change the work mode of the power supply 41 to the adaptive mode when being operated, so that the user can operate the first operation member 51 to change the work mode of the power supply 41 to the adaptive mode. In addition, when the first operation member 51 is operated to change the power supply 41 to the adaptive mode, the at least one main air inlet 511 is open, so that outside air can enter the airflow channel 3 through the at least one main air inlet 511. In this case, the ventilation area of the air inlet may be determined mainly based on a total ventilation area of the open main air inlet 511.

When there are a plurality of adaptive modes, the first operation member 51 is configured to switch a type of the adaptive mode, and to adjust the main air inlet 511 to enable the main air inlet 511 to have different ventilation areas in different adaptive modes. Therefore, the main air inlet 511 has a larger ventilation area in an adaptive mode with a large range power.

For example, the first operation member 51 is operated to switch the first adaptive mode to the second adaptive mode, and switch the ventilation area of the main air inlet 511 to a second ventilation area. Alternatively, the first operation member 51 is operated to switch the second adaptive mode to the first adaptive mode, and switch the ventilation area of the main air inlet 511 to a first ventilation area.

It should be noted that, when the power supply 41 is in the first adaptive mode, the electric power provided by the power supply 41 for the atomization assembly 2 is in positive correlation with the puff force, and the puff force is in positive correlation with an air inlet amount. In other words, when the power supply 41 is in the first adaptive mode, the electric power provided by the power supply 41 for the atomization assembly 2 is in positive correlation with the air inlet amount. However, when the electric power provided by the power supply 41 for the atomization assembly 2 changes as the puff force or the air inlet amount changes, the ventilation area of the main air inlet 511 or the first ventilation area may maintain unchanged. Similarly, when the power supply 41 is in the second adaptive mode, and the electric power provided by the power supply 41 for the atomization assembly 2 changes as the puff force or the air inlet amount changes, the ventilation area of the main air inlet 511 or the second ventilation area may maintain unchanged.

The first ventilation area of the main air inlet 511 when the power supply 41 is in the first adaptive mode is less than the second ventilation area when the power supply 41 is in the second adaptive mode. Therefore, when the puff force is the same, an air inlet amount when the power supply 41 is in the first adaptive mode may be less than an air inlet amount when the power supply 41 is in the second adaptive mode. In addition, when the puff force is the same, the electric power provided by the power supply 41 for the atomization assembly 2 in the first adaptive mode is less than the electric power provided by the power supply 41 for the atomization assembly 2 in the second adaptive mode.

In some embodiments, refer to FIG. 1, the aerosol generation device 100 includes a first switch element 71. At least a part of the first switch element 71 is disposed in linkage with the first operation member 51, or the first switch element 71 is configured to sense a position of the first operation member 51. Therefore, the first operation member 51 can be driven to move, to change a status of the first switch element 71 or enable the first switch element 71 to generate a signal associated with the position of the first operation member 51.

That the first operation member 51 is driven to move includes that the first operation member 51 is driven to rotate, to change an angle of the first operation member 51, or that the first operation member 51 is driven to move along a straight line or a curved line, to change the position of the first operation member 51, or that the first operation member 51 is driven to move, to change both the angle and the position of the first operation member 51.

In some embodiments, the first switch element 71 includes a movable switch, so that the movable switch can be driven to move by using the first operation member 51, to change a position and/or an angle of the movable switch, thereby changing the work mode of the power supply 41. In some embodiments, the first switch element 71 includes a sensing switch configured to sense the position or the angle of the first operation member 51. For example, the sensing switch may include a Hall sensing switch. Therefore, the position or the angle of the first operation member 51 can be sensed in a contact or non-contact manner. Alternatively, for example, the sensing switch may include a micro switch, so that the micro switch can be contacted when the first operation member 51 moves to a preset position or angle, thereby triggering the micro switch.

In some embodiments, refer to FIG. 1 to FIG. 4, the first operation member 51 is configured to be movable between a first position and a second position. In addition, the power supply 41 is in a first adaptive mode when the first operation member 51 is located at the first position, and is in a second adaptive mode when the first operation member 51 is located at the second position. The first operation member 51 is operated to move between the first position and the second position, so that the work mode of the power supply 41 can be switched from the first adaptive mode to the second adaptive mode, or switched from the second adaptive mode to the first adaptive mode. It is convenient for the user to freely switch the work mode of the power supply 41 in the use process of the aerosol generation device 100.

In some embodiments, refer to FIG. 1 to FIG. 4, the main air inlet 511 is provided on the first operation member 51. Therefore, when the position or the angle of the first operation member 51 changes, the position or the angle of the main air inlet 511 correspondingly changes.

In an example, refer to FIG. 2 and FIG. 4, the main air inlet 511 comprises a plurality of main air inlets 511. In different adaptive modes, or when the first operation member 51 is located at different positions or angles, the quantity of the main air inlets 511 that are open differs. Outside air can flow into the airflow channel 3 through the main air inlets 511 that are open. Therefore, in different adaptive modes, or when the first operation member 51 is located at different positions or angles, the airflow channel 3 has different ventilation areas.

For example, the quantity of the main air inlets 511 that are open when the first operation member 51 is located at the first position is less than the quantity of the main air inlets 511 that are open when the first operation member 51 is located at the second position.

For example, when the first operation member 51 is located at the first position, two of the main air inlets 511 are open. When the first operation member 51 is located at the second position, three of the main air inlets 511 are open.

In an example, refer to FIG. 2 and FIG. 4, the main air inlet 511 includes a first air inlet 5111 and a second air inlet 5112. A ventilation area of the second air inlet 5112 is larger than a ventilation area of the first air inlet 5111. The first air inlet 5111 is open and the second air inlet 5112 is closed when the first operation member 51 is located at the first position. The second air inlet 5112 is open when the first operation member 51 is located at the second position. When the main air inlet 511 is closed, an air path between the main air inlet 511 and the airflow channel 3 breaks, or an air path between the main air inlet 511 and outside air breaks. As a result, the outside air cannot enter or has difficulty entering the airflow channel 3 through the closed main air inlet 511.

For example, when the first operation member 51 is located at the first position, two first air inlets 5111 are open, and the second air inlets 5112 are all closed. When the first operation member 51 is located at the second position, the two first air inlets 5111 are open, and at least one of the second air inlets 5112 is open.

Alternatively, for example, when the first operation member 51 is located at the first position, at least one of the first air inlets 5111 is open, and all second air inlets 5112 are closed. When the first operation member 51 is located at the second position, the quantity of the first air inlets 5111 that are open is reduced or all of the first air inlets 5111 are closed, and at least one of the second air inlets 5112 is open.

In some embodiments, the first air inlet 5111 and the second air inlet 5112 are both circular pores. A pore diameter of the first air inlet 5111 is D1, a pore diameter of the second air inlet 5112 is D2, and D1<D2. In an example, D1 is less than 0.95 mm, and D2 may be greater than or equal to 0.95 mm. In an example, D2 is greater than 0.85 mm, and D1 may be less than or equal to 0.85 mm. In an example, D1 is equal to 0.85 mm, and D2 is equal to 0.95 mm.

In some embodiments, refer to FIG. 5 and FIG. 6, the first operation member 51 is configured to be further movable to a third position. The main air inlets 511 are all closed when the first operation member 51 is located at the third position. Therefore, when the first operation member 51 is located at the third location, the adaptive mode is disabled, and the work mode of the power supply 41 cannot be the adaptive mode. The first position may be located between the third position and the second position, but this is not limited thereto.

In some embodiments, refer to FIG. 1, FIG. 7, and FIG. 8, the aerosol generation device 100 includes an auxiliary air inlet assembly 6. The auxiliary air inlet assembly 6 is configured to be open in the constant mode, to enable outside air to enter the airflow channel 3 through the auxiliary air inlet assembly 6, thereby increasing the ventilation area of the air inlet, and is configured to be closed in the adaptive mode. When the auxiliary air inlet assembly 6 is closed, the outside air cannot enter the airflow channel 3 by large amount through the auxiliary air inlet assembly 6, and the outside air can even be prevented from entering the airflow channel 3 through the auxiliary air inlet assembly 6.

The air inlet includes an auxiliary air inlet 621 disposed on the auxiliary air inlet assembly 6. When the auxiliary air inlet assembly 6 is open, the auxiliary air inlet 621 is open. When the auxiliary air inlet assembly 6 is closed, the auxiliary air inlet 621 is closed. In other words, when the work mode of the power supply 41 is the adaptive mode, the auxiliary air inlet 621 is closed. When the work mode of the power supply 41 is the constant mode, the auxiliary air inlet 621 is open.

When there are a plurality of adaptive modes, the auxiliary air inlet 621 may be closed when the power supply 41 is in any one of the adaptive modes. When the power supply 41 is switched from any one of the adaptive modes to the constant mode by using the operation assembly 5, the auxiliary air inlet assembly 6 is open.

After the auxiliary air inlet assembly 6 is open, when the auxiliary air inlet assembly 6 or the auxiliary air inlet 621 has a constant ventilation area, and the main air inlet 511 has different ventilation areas in different adaptive modes, when different adaptive modes are switched to the constant mode, the total ventilation area of the air inlet is different. For example, a total ventilation area of the air inlet when the power supply 41 is switched from the second adaptive mode to the constant mode is greater than a total ventilation area when the power supply 41 is switched from the first adaptive mode to the constant mode.

In some embodiments, refer to FIG. 1, FIG. 7, FIG. 8, and FIG. 10, the aerosol generation device 100 includes a second operation member 52. The second operation member 52 is configured to change the power supply 41 to the constant mode when being operated, so that the user can operate the second operation member 52 to change the work mode of the power supply 41 to the constant mode. In addition, when the second operation member 52 is operated to switch the power supply 41 to the constant mode, the auxiliary air inlet 621 is open, so that outside air can enter the airflow channel 3 through the auxiliary air inlet 621. In this case, the ventilation area of the air inlet includes a ventilation area of the auxiliary air inlet 621.

Further, the first operation member 51 and the second operation member 52 are independent of each other, so that the first operation member 51 and the second operation member 52 can be operated independently. Therefore, when the second operation member 52 is operated, the first operation member 51 may be maintained at an original position or an original angle. Therefore, the work mode of the power supply 41 may be changed to the adaptive mode by operating the first operation member 51, and then the power supply 41 may be switched from the current adaptive mode to the constant mode by operating the second operation member 52. In this case, because the position or the angle of the first operation member 51 is not changed, the total ventilation area of the open main air inlet 511 or the main air inlet 511 that can be in fluid communication with the outside air and the fluid channel remains unchanged. Therefore, after the power supply 41 is switched from the current adaptive mode to the constant mode by operating the second operation member 52, the ventilation area of the air inlet includes a sum of the ventilation area of the main air inlet 511 in the previous work mode and the ventilation area of the auxiliary air inlet 621 in the current constant mode.

For example, after the work mode of the power supply 41 is changed to the first adaptive mode by operating the first operation member 51, therefore the airflow channel 3 has the first ventilation area, and then the work mode of the power supply 41 is switched from the first adaptive mode to the constant mode by operating the second operation member 52, the ventilation area of the air inlet includes a sum of the first ventilation area and the ventilation area of the auxiliary air inlet 621.

In some embodiments, refer to FIG. 1 and FIG. 9, the aerosol generation device 100 includes a second switch element 72. The second operation member 52 may be driven to move, to change the status of the second switch element 72. When the second switch element 72 is triggered, the work mode of the power supply 41 is switched to the constant mode.

That the second operation member 52 is driven to move includes that the second operation member 52 is driven to rotate, to change an angle of the second operation member 52, or that the second operation member 52 is driven to move along a straight line or a curved line, to change the position of the second operation member 52, or that the second operation member 52 is driven to move, to change both the angle and the position of the second operation member 52.

In some embodiments, the second operation member 52 is configured to be movable between a fourth position and a fifth position. When the second operation member 52 is located at the fifth position, the second switch element 72 is triggered to switch the power supply 41 from the current adaptive mode or work mode to the constant mode. When the second operation member 52 returns to the fourth position, the power supply 41 is switched from the constant mode back to a previous adaptive mode or work mode.

For example, after the work mode of the power supply is changed to the second adaptive mode by operating the first operation member 51, therefore the air inlet has the second ventilation area, the power supply 41 provides the second range power for the atomization assembly 2 during puffing, and then the work mode of the power supply 41 is switched from the second adaptive mode to the constant mode by operating the second operation member 52, the ventilation area of the air inlet includes a sum of the second ventilation area and the ventilation area of the auxiliary air inlet 621. In addition, the power supply 41 provides a constant electric power for the atomization assembly 2, and the constant electric power is greater than the largest electric power in the second range power. Then, after the second operation member 52 returns to the fourth position, the power supply 41 restores to the second adaptive mode, the auxiliary air inlet assembly 6 is closed, the ventilation area of the air inlet is the second ventilation area again, and the power supply 41 provides the second range power for the atomization assembly 2 during puffing.

In some embodiments, the aerosol generation device 100 further includes a controller 42. The controller 42 can respond to an operation of the first operation member 51. In other words, the controller 42 can respond to a status change of the first switch element 71 or can respond to the signal that is generated by the first switch element 71, and that is associated with the position of the first operation member 51, to control the work mode of the power supply 41 to be the adaptive mode. The controller 42 can further respond to an operation of the second operation member 52. In other words, the controller 42 can respond to a status change of the second switch element 72 or can respond to the signal that is generated by the second switch element 72 and that is associated with the position of the second operation member 52, to control the work mode of the power supply 41 to be the constant mode.

Further, a response level of the controller 42 to the operation of the second operation member 52 is higher than a response level of the controller 42 to the operation of the first operation member 51. Alternatively, a response level of the controller 42 to the status change of the second switch element 72 or the signal that is generated by the second switch element 72 and that is associated with the position of the second operation member 52 is higher than a response level of the controller 42 to the status change of the first switch element 71 or the signal that is generated by the first switch element 71 and that is associated with the position of the first operation member 51.

Therefore, when the first operation member 51 and the second operation member 52 are simultaneously operated, the controller 42 preferably responds to the operation of the second operation member 52. In addition, when the work mode of the power supply 41 is the constant mode, the controller 42 may not respond to a change in the position or the angle of the first operation member 51. When the work mode of the power supply 41 is the adaptive mode, if the second operation member 52 is effectively operated, the controller 42 may respond to the operation of the second operation member 52, so that the work mode of the power supply 41 is switched from the adaptive mode to the constant mode.

The controller 42 may include at least one processor. The processor may include a logic gate array or may include a combination of a general-purpose microprocessor and a memory storing programs executable in the microprocessor. In addition, a person skilled in the art should understand that the controller 42 may include another type of hardware.

In some embodiments, the second switch element 72 includes a normally-open pressure switch, and the normally-open pressure switch is configured to be triggered when being pressed, and maintained in an off state when being not pressed. The second operation member 52 is configured to be disposed spaced away from the normally-open pressure switch when the second operation member 52 is located at the fourth position, and to press against the normally-open pressure switch when the second operation member 52 is located at the fifth position, so that the power supply 41 provides the constant electric power for the atomization assembly 2.

In some embodiments, refer to FIG. 1 and FIG. 9, the aerosol generation device 100 further includes a first return member 8. The first return member 8 acts on the second operation member 52 to provide an action force, enabling the second operation member 52 to automatically return from the fifth position to the fourth position.

When the user stops operating the second operation member 52, or when the user cancels an action force applied to the second operation member 52, the second operation member 52 can automatically return to the fourth position under driving of the first return member 8, so that the second operation member 52 is disposed spaced away from the normally-open pressure switch again, and the power supply 41 is automatically switched from the constant mode back to the previous work mode.

For example, the user operates the second operation member 52 to switch the power supply 41 from the first adaptive mode to the constant mode. Then, the user stops operating the second operation member 52, or the user cancels an action force applied to the second operation member 52. The first return member 8 drives the second operation member 52 to automatically return to the fourth position, and the power supply 41 is automatically switched from the constant mode back to the first adaptive mode.

Similarly, the user operates the second operation member 52 to switch the power supply 41 from the second adaptive mode to the constant mode. Then, the user stops operating the second operation member 52, or the user cancels an action force applied to the second operation member 52. The first return member 8 drives the second operation member 52 to automatically return to the fourth position, and the power supply 41 is automatically switched from the constant mode back to the second adaptive mode.

In the embodiment shown in FIG. 1 and FIG. 9, the aerosol generation device 100 further includes a housing 9 and a circuit board 73 electrically connected to the power supply. The circuit board 73 is disposed on the housing. The atomization assembly 2 and the power supply assembly 4 are both disposed inside the housing 9. The second switch element 72 is disposed on the circuit board 73. The second operation member 52 is disposed on a partial outer side of the housing 9. The first return member 8 is disposed between the housing 9 and the second operation member 52, and elastically presses against the housing 9 and the second operation member 52, to support the second operation member 52, so that the second operation member 52 is maintained at the fourth position. In a process in which the user operates the second operation member 52 to move the second operation member 52 from the fourth position to the fifth position, the first return member 8 undergoes elastic deformation to store elastic potential energy. After the user stops operating the second operation member 52, or the user cancels the action force applied to the second operation member 52, the first return member 8 releases at least a part of the elastic potential energy, to drive the second operation member 52 to return to the fourth position.

The first return member 8 may include a silicon article or a spring. This is not specifically limited herein.

In some embodiments, the second operation member 52 is disposed on a side surface of the housing 9, so that, when the user holds the aerosol generation device 100, a thumb or remaining four fingers may contact the second operation member 52, thereby facilitating the user to operate the second operation member 52. In this way, when the user needs to operate the second operation member 52, the user may not need to change the posture of holding the aerosol generation device 100, to help facilitate switching the power supply 41 from another work mode to the constant mode at any time.

Further, the second operation member 52 is configured to be pressed by the user to move from the fourth position to the fifth position. Preferably, a direction in which the user presses the second operation member 52 is parallel to the radial direction Y.

In some embodiments, the total length of the aerosol generation device 100 along the axial direction X is L1. The length of the second operation member 52 along the axial direction X is L2. L2≥L1/2. When the axial length of the second operation member 52 is large, the user can more easily operate the second operation member 52. Preferably, L2/L1≥⅔.

In some embodiments, referring to FIG. 1 and FIG. 9, the aerosol generation device 100 further includes a connection member 10. The connection member 10 includes a second connection portion 102 and a first connection portion 101 that extends along the axial direction X. The first connection portion 101 and the second connection portion 102 are spaced away from each other in a direction perpendicular to the axial direction X. In addition, the first connection portion 101 and the second connection portion 102 may further be spaced away from each other in a direction perpendicular to the radial direction Y. The first connection portion 101 is connected to the second operation member 52. The second connection portion 102 is connected to the housing 9. A length L3 of the first connection portion 101 along the axial direction X satisfies: L3/L2≥½. The connection member 10 is located between the housing 9 and the second operation member 52. When the length L3 of the first connection portion 101 along the axial direction X is closer to the length L2 of the second operation member 52 along the axial direction X, the user is more enabled to translate the second operation member 52 from the fourth position to the fifth position by pressing any part of the second operation member 52. Preferably, L3/L2≥⅔.

Further, the second connection portion 102 is in rotational connection to the housing 9, and the first connection portion 101 is in rotational connection to the second operation member 52, so that the connection member 10 can rotate relative to the housing 9 and the second operation member 52 when the second operation member 52 is pressed to move from the fourth position to the fifth position, thereby reducing resistance of the connection member 10 to a process in which the second operation member 52 moves from the fourth position to the fifth position. Similarly, in a process in which the first return member 8 drives the second operation member 52 to move from the fifth position to the fourth position, the connection member 10 rotates relative to the housing 9 and the second operation member 52, so that resistance of the connection member 10 to a process in which the second operation member 52 moves from the fifth position to the fourth position can be reduced.

In some embodiments, the auxiliary air inlet assembly 6 is closed when the second operation member 52 is located at the fourth position, and the auxiliary air inlet assembly 6 is open when the second operation member 52 is located at the fifth position.

Further, refer to FIG. 7 and FIG. 8, the auxiliary air inlet assembly 6 includes a piston 61 and an air inlet member 62. The auxiliary air inlet 621 is disposed on the air inlet member 62, and the piston 61 blocks the auxiliary air inlet 621, so that the auxiliary air inlet assembly 6 is normally closed. The second operation member 52 is configured to drive the piston 61 to open the auxiliary air inlet 621 when the second operation member 52 moves from the fourth position to the fifth position.

In some embodiments, the auxiliary air inlet assembly 6 is configured to be automatically closed when the second operation member 52 returns to the fourth position.

Further, refer to FIG. 7 and FIG. 8, the auxiliary air inlet assembly 6 further includes a second return member 63. The piston 61 includes a sealing portion 611. The second return member 63 is connected to the air inlet member 62 and the piston 61, to enable the sealing portion 611 to automatically restore to block the auxiliary air inlet 621 when the second operation member 52 returns to the fourth position.

Further, the piston 61 further includes a driving portion 612 connected to the sealing portion 611. A cavity is provided inside the air inlet member 62. An air outlet hole 622 communicating with the fluid channel 3 is further provided on the air inlet member 62. The sealing portion 611 is movably disposed in the cavity. The driving portion 612 passes through the auxiliary air inlet 621 to be located outside the air inlet member 62, to be pressed by the second operation member 52.

In a process in which the second operation member 52 moves from the fourth position to the fifth position, the second operation member 52 presses against the driving portion 612 of the piston 61, and further pushes the sealing portion 611 of the piston 61 away from the auxiliary air inlet 621. The auxiliary air inlet 621 is therefore open, so that the outside air can enter the cavity of the air inlet member 62 through the auxiliary air inlet 621, and then flow into the airflow channel 3 from the air outlet hole 622 of the air inlet member 62.

Cooperation between the second operation member 52 and the housing 9 may be gap cooperation, so that the outside air can enter the auxiliary air inlet 621 through a gap between the housing 9 and the second operation member 52.

A cross-sectional area of the sealing portion 611 is greater than an area of the auxiliary air inlet 621, to prevent the sealing portion 611 from being moved out through the auxiliary air inlet 621, so that the connection between the piston 61 and the air inlet member 62 can be maintained.

The air inlet member 62 further includes a shoulder portion 623. The shoulder portion 623 defines a part of the boundary of the cavity. The second return member 63 may be disposed in the cavity. One end of the second return member 63 presses against the shoulder portion 623, and the other end presses against the piston 61.

The second return member 63 is elastic and can be elastically deformed. The second return member 63 may include a silicon article or a spring.

In some embodiments, the auxiliary air inlet 621 is a circular pore, and the pore diameter of the auxiliary air inlet 621 is D3. In an example, D3 is greater than or equal to D2. In an example, D1<D3<D2. In an example, D3 is less than or equal to D2. In an example, 0.8 mm≤D3≤1.2 mm.

In some embodiments, when the power supply 41 is in the adaptive mode, the power supply 41 provides an electric power for only one of the first heating element 2211 and the second heating element 2212, and provides an electric power for only one of the third heating element 2221 and the fourth heating element 2222.

In some embodiments, when the power supply 41 is in the adaptive mode, the power supply 41 alternately provides an electric power for the first heating element 2211 and the second heating element 2212, and alternately provides an electric power for the third heating element 2221 and the fourth heating element 2222.

For example, when the power supply 41 is in the adaptive mode, in a first time period or during the first puffing, the power supply 41 simultaneously provides electric power for the first heating element 2211 and the third heating element 2221. In a second time period or during the second puffing, the power supply 41 simultaneously provides electric power for the second heating element 2212 and the fourth heating element 2222. In a third time period or during the third puffing, the power supply 41 simultaneously provides electric power for the first heating element 2211 and the third heating element 2221 again. In a fourth time period or during fourth puffing, the power supply 41 simultaneously provides electric power for the second heating element 2212 and the fourth heating element 2222 again. The rest can be deduced by analogy, and details are not described herein again.

In some embodiments, refer to FIG. 11, the first heating element 2211 is connected to the third heating element 2221 in series, and the second heating element 2212 is connected to the fourth heating element 2222 in series. The first heating element 2211 is connected to the second heating element 2212 in parallel, and the third heating element 2221 is connected to the fourth heating element 2222 in parallel.

In some embodiments, the power supply 41 simultaneously provides electric power for the first heating element 2211, the second heating element 2212, the third heating element 2221, and the fourth heating element 2222 in the constant mode.
