FIG. 1 illustrates an electronic atomization device 1 in the present disclosure. The electronic atomization device 1 is configured to accommodate an aerosol generating substrate and heat the aerosol generating substrate after being energized to atomize same. The aerosol generating substrate includes, but is not limited to, a material used for a medical purpose, a health purpose, a cosmetic purpose, or the like. The shape of the electronic atomization device 1 is not limited, for example, the electronic atomization device 1 may be of various shapes such as a square column, an elliptic column, a racing-track column, or a cylinder.

As shown in FIG. 2 to FIG. 4, the electronic atomization device 1 includes a first liquid storage and atomization module 40 and a second liquid storage and atomization module 50. The first liquid storage and atomization module 40 includes a first airflow channel 44, a first liquid storage cavity 42 configured to store a first aerosol generating substrate, and a first atomization assembly 43 in flow communication with the first liquid storage cavity 42. The first atomization assembly 43 is configured to atomize the first aerosol generating substrate in the first liquid storage cavity 42 to generate a first aerosol. The second liquid storage and atomization module 50 includes a second airflow channel 54, a second liquid storage cavity 52 configured to store a second aerosol generating substrate, and a second atomization assembly 53 in flow communication with the second liquid storage cavity 52. The second atomization assembly 53 is configured to atomize the second aerosol generating substrate in the second liquid storage cavity 52 to generate a second aerosol. The first airflow channel 44 is communicated with the second airflow channel 54. In this way, the first aerosol generated after the first atomization assembly 43 is atomized and the second aerosol generated after the second atomization assembly 53 is atomized can be mixed, and the mixed aerosol is then outputted to the outside for a user to vape.

For example, the electronic atomization device 1 may alternatively have three or more liquid storage and atomization modules.

The heating manners of the first atomization assembly 43 and the second atomization assembly 53 are not limited. For example, the first atomization assembly 43 and the second atomization assembly 53 may use one or more heating manners such as resistance heating, electromagnetic heating, infrared heating, and chemical heating. In addition, the first atomization assembly 43 and the second atomization assembly 53 may have the same or different heating manners.

The liquid storage volumes (or the liquid storage amounts) of the first liquid storage cavity 42 and the second liquid storage cavity 52 may be the same, or may be different. The composition components of the first aerosol generating substrate and the second aerosol generating substrate may be the same or may be different. For example, the first aerosol generating substrate and/or the second aerosol generating substrate contains nicotine, and the content of nicotine contained in the first and second aerosol generating substrates may be the same or may be different. Alternatively, only one of the first aerosol generating substrate and the second aerosol generating substrate contains nicotine, and the other one contains a flavor agent.

In an aspect, the first liquid storage cavity 42 and/or the second liquid storage cavity 52 may be a liquid storage cavity, and an aerosol generating substrate is injected into the liquid storage cavity.

In an aspect, the first liquid storage cavity 42 and/or the second liquid storage cavity 52 may alternatively include a liquid storage piece. The liquid storage piece may store a liquid by using a capillarity action or another action force. In an aspect, the liquid storage piece is a cellular material having a capillarity action, and includes, but is not limited to, a cotton material (for example, natural cotton and/or rayon) or an organic cellular material (for example, ceramics or glass fiber).

The electronic atomization device 1 further includes a control module 70. The control module 70 is separately connected to the first atomization assembly 43 and the second atomization assembly 53, to control atomization work of the first atomization assembly 43 and/or the second atomization assembly 53. The first atomization assembly 43 and the second atomization assembly 53 may be connected to the control module 70 in parallel. The first atomization assembly 43 and the second atomization assembly 53 may work simultaneously, or may work independently (that is, one of the first atomization assembly 43 and the second atomization assembly 53 performs the atomization work). For example, the first atomization assembly 43 and the second atomization assembly 53 may alternatively be connected in series.

In an aspect, the power of the first atomization assembly 43 and/or the second atomization assembly 53 may be adjusted. In this manner, the first atomization assembly 43 and the second atomization assembly 53 may be enabled to generate aerosols of a plurality of tastes. The manner of power adjustment may be adjustment inputted by a user, or may be automatic adjustment by the electronic atomization device 1 according to factors such as the type, environment, and suction force of the aerosol generating substrate.

In an aspect, the first atomization assembly 43 and the second atomization assembly 53 may perform power adjustment in a manner such as touch, key sound control, or gesture control. Correspondingly, the electronic atomization device 1 further includes an input module 20, configured to receive an input operation of a user and transmit the input operation to the control module 70. The control module 70 then controls, according to the input operation of the user, on/off of the first atomization assembly 43 and/or the second atomization assembly 53, and/or adjusts the power of the first atomization assembly 43 and/or the second atomization assembly 53. The input operation of the user may be one input operation, or may be a plurality of input operations.

In an aspect, the input module 20 may include one or more of a mechanical key, touch, sound control, gesture control, and the like. The input module 20 may be at least partially exposed to the outside, to facilitate an operation by a user. The user may start or stop, by using the input module 20, atomization work of the first atomization assembly 43 and/or the second atomization assembly 53, or may adjust the power of the first atomization assembly 43 and/or the second atomization assembly 53 by using the input module 20.

In an aspect, the electronic atomization device 1 further includes a battery 30, configured to supply power to the first atomization assembly 43 and the second atomization assembly 53. The battery 30 is connected to the first atomization assembly 43 and the second atomization assembly 53 by using a control module 70. The control module 70 may control the battery 30 to supply or not to supply power to the first atomization assembly 43 and/or the second atomization assembly 53, and may further control the power of supplying power to the first atomization assembly 43 and/or the second atomization assembly 53 by the battery 30, and so on. Specifically, the power supplied to the first atomization assembly 43 and/or the second atomization assembly 53 may be controlled by controlling at least one of a voltage or a current supplied to the first atomization assembly 43 and/or the second atomization assembly 53. The voltage or the current may be controlled by pulse width modulation.

In a heating process, the atomization assembly may be heated by using a constant power, or may be heated by using a variable power. The constant power refers to that the power of the atomization assembly is constant in the heating process, and the variable power refers to that the power of the atomization assembly changes in the heating process.

The electronic atomization device 1 may have the following working modes.

In an aspect, the control module 70 may be configured to control the power supply to the first atomization assembly 43 and/or the second atomization assembly 53 according to a mode selected by a user before vaping starts.

Referring to FIG. 5, FIG. 5 is a schematic flowchart of a control method for an electronic atomization device 1 according to an example of the present disclosure. The control method for the electronic atomization device 1 may include: S11: Obtain an input operation of a user. S12: Control, in response to the input operation, the electronic atomization device 1 to run in a corresponding mode.

In an aspect, the control module 70 may further be configured to adjust the power of the first atomization assembly 43 and/or the second atomization assembly 53 according to an interaction parameter before vaping starts and/or in a process of the vaping. The interaction parameter includes one of, or a combination of at least two of, the accumulated energy supplied to the first atomization assembly 43 and/or the second atomization assembly 53, the accumulated vaping time, the accumulated number of times of vaping, or the vaping strength.

Referring to FIG. 6, FIG. 6 is a schematic flowchart of a control method for an electronic atomization device 1 according to an example of the present disclosure. The control method for the electronic atomization device 1 may include: S21: Obtain an interaction parameter, the interaction parameter including one of, or a combination of at least two of, the accumulated energy supplied to the first atomization assembly 43 and/or the second atomization assembly 53, the accumulated vaping time, the accumulated number of times of vaping, or the vaping strength. S22: Adjust the power of the first atomization assembly 43 and/or the second atomization assembly 53 in response to the interaction parameter.

Further, as shown in FIG. 2 to FIG. 4, in an aspect, the electronic atomization device 1 may further include an airflow sensor 80. The airflow sensor 80 is communicated with an airflow path 11 and is electrically connected to the control module 70. The airflow sensor 80 may be configured to detect a change in a vaping airflow in the airflow path 11, for example, measuring the pressure or the flow rate in the airflow path 11. The control module 70 may control, according to a signal sent by the airflow sensor 80, whether to start the electronic atomization device 1, and/or adjust the power of the first atomization assembly 43 and/or the second atomization assembly 53.

In an aspect, the electronic atomization device 1 includes a housing 10, and a battery 30, a control module 70, an airflow sensor 80, a first liquid storage and atomization module 40, and a second liquid storage and atomization module 50 that are all accommodated in the housing 10. In an aspect, the first liquid storage and atomization module 40 and the second liquid storage and atomization module 50 may be disposed in the housing 10 in a non-detachable manner. The electronic atomization device 1 may be an entirely non-detachable structure. “Non-detachable” means that the electronic atomization device 1 cannot be detached without being damaged, and replacement is performed on the entire machine after the aerosol generating substrate in the electronic atomization device 1 is used up. In an aspect, the electronic atomization device 1 may alternatively be a partially detachable structure. For example, the first liquid storage and atomization module 40 and/or the second liquid storage and atomization module 50 may alternatively be disposed in the housing 10 in a detachable manner.

The input module 20 may be disposed on the upper portion of the housing 10. For example, the input module 20 may be disposed on the top wall of the housing 10 or disposed close to the top wall. In this way, when a user holds the electronic atomization device 1 in hands, the risk that the user touches the input module 20 by accident may be reduced. For example, the input module 20 may alternatively be disposed at another portion of the housing 10, for example, the middle portion or the lower portion of the housing 10.

An air intake vent 111 and an air discharge vent 112 are formed in the housing 10, and both the first airflow channel 44 and the second airflow channel 54 are communicated with the air intake vent 111 and the air discharge vent 112. The air intake vent 111, the first airflow channel 44, the second airflow channel 54, and the air discharge vent 112 jointly form the airflow path 11. An external airflow enters through the air intake vent 111, flows through the first atomization assembly 43 and the second atomization assembly 53, and carries away an aerosol generated after atomization by the first atomization assembly 43 and the second atomization assembly 53 to the air discharge vent 112, for a user to vape.

In an aspect, the first atomization assembly 43 and the second atomization assembly 53 may be arranged between the air intake vent 111 and the air discharge vent 112 in a series-connected manner, and the second atomization assembly 53 is located downstream of the first atomization assembly 43. That is, the air intake vent 111, the first airflow channel 44, the second airflow channel 54, and the air discharge vent 112 are sequentially communicated. An external airflow enters through the air intake vent 111, first flows through the first atomization assembly 43, carries away an aerosol generated after atomization by the first atomization assembly 43, further flows to the second atomization assembly 53, is mixed with an aerosol generated after atomization by the second atomization assembly 53, and then flows out through the air discharge vent 112.

For example, the first atomization assembly 43 and the second atomization assembly 53 may alternatively be arranged between the air intake vent 111 and the air discharge vent 112 in a parallel-connected manner. That is, an airflow entered through the air intake vent 111 are divided into two airflows to respectively enter the first airflow channel 44 and the second airflow channel 54, to carry away the aerosols generated by the first atomization assembly 43 and the second atomization assembly 53 after atomization, then merge into a merging channel for mixing, and finally exit through the air discharge vent 112.

In an aspect, the air discharge vent 112 may be provided on the top wall of the housing 10, and the air intake vent 111 may be disposed on the bottom wall of the housing 10. The air intake vent 111, the first airflow channel 44, the second airflow channel 54, and the air discharge vent 112 are sequentially communicated from bottom to top. An airflow channel defined in the housing 10 extends approximately along the vertical direction.

For example, the air intake vent 111 may alternatively be provided at another position of the housing 10, for example, the side wall or the top wall of the housing 10. In addition, an airflow channel defined in the housing 10 may alternatively be disposed in a curved manner.

In an aspect, the electronic atomization device 1 may further include an airflow adjusting piece 60. The airflow adjusting piece 60 is slidably disposed in the housing 10, and is configured to adjust the size of the air intake vent area of the air intake vent 111, so as to achieve the purpose of adjusting the suction resistance. When the electronic atomization device 1 does not need to be used, the air intake vent 111 may be fully covered by sliding the airflow adjusting piece 60, to prevent dirt and the like from entering the electronic atomization device 1 through the air intake vent 111.

In an aspect, a plurality of air vents 61 are disposed at intervals on the airflow adjusting piece 60. The plurality of air vent 61 may have different cross-sectional areas, and the cross-sectional areas of the plurality of air vents 61 may sequentially increase or decrease in the sliding direction of the airflow adjusting piece 60. Different air vents 61 are aligned with the air intake vent 111, so as to adjust the suction resistance.

For example, the airflow adjusting piece 60 may further be provided with a ventilation passage extending along the sliding direction of the airflow adjusting piece 60. The cross sectional area of the ventilation passage gradually increases or decreases in the extending direction of the airflow adjusting piece 60. When the airflow adjusting piece 60 continuously slides, the size of the air intake vent area of the air intake port 301 changes.

In an aspect, the second liquid storage and atomization module 50 may be accommodated in the upper portion of the housing 10, and the battery 30 and the first liquid storage and atomization module 40 may be accommodated in the lower portion of the housing 10. Further, the battery 30 may be at least partially disposed in parallel with the first liquid storage and atomization module 40, so that a compact design of the electronic atomization device 1 can be achieved. The control module 70 includes a circuit board 71. Both the circuit board 71 and the airflow sensor 80 may be accommodated at the lower portion of the housing 10, so that the circuit board 71 can be in circuit connection with the battery 30, the airflow sensor 80, and the like.

The liquid storage volume of the first liquid storage cavity 42 is smaller than that of the second liquid storage cavity 52. In this way, a space for installing the battery 30 is given at the lower portion of the housing 10. Because the liquid storage volume of the second liquid storage cavity 52 is relatively large, preferably, the power of the second atomization assembly 53 may be adjusted.

The first atomization assembly 43 includes a first heat generating body 432 electrically connected to the control module 70. The second atomization assembly 53 includes a second heat generating body 532 electrically connected to the control module 70. The first heat generating body 432 and the second heat generating body 532 can generate heat after being energized, to heat the aerosol generating substrate.

The first heat generating body 432 and the second heat generating body 532 may be resistive heat generating bodies that can convert electric energy into thermal energy by using a resistive heat effect generated when a current passes through an electrically conductive material. The specific shapes of the resistive heat generating bodies are not limited, for example, the resistive heat generating bodies may be a mesh, an array, or cloth formed by an electrically conductive thread or an electrically conductive sheet. For example, the first heat generating body 432 and/or the second heat generating body 532 may alternatively be a heat generating body in another form, such as an electromagnetic heat generating body or an infrared heat generating body.

In an aspect, the first atomization assembly 43 further includes a first liquid guiding body 431 in flow communication with the first liquid storage cavity 42, and the first liquid guiding body 431 can suction the aerosol generating substrate from the first liquid storage cavity 42 and transfer the aerosol generating substrate to the first heat generating body 432. The second atomization assembly 53 further includes a second liquid guiding body 531 in flow communication with the second liquid storage cavity 52, and the second liquid guiding body 531 can suction the aerosol generating substrate from the second liquid storage cavity 52 and transfer the aerosol generating substrate to the second heat generating body 532.

The first liquid guiding body 431 and the second liquid guiding body 531 may use any structure that can transmit or transfer the aerosol generating substrate to the heat generating body. Usually, the first liquid guiding body 431 and the second liquid guiding body 531 may perform liquid guiding by using a capillarity action.

In an aspect, the first liquid guiding body 431 and the second liquid guiding body 531 may use a cellular material having a capillarity action, and includes, but is not limited to, a cotton material (for example, natural cotton and/or rayon) or an organic cellular material (for example, ceramics or glass fiber). For example, micro-structures, such as micro pores or micro grooves, having a capillarity action may alternatively be formed on the liquid guiding body by using a micro-manufacturing process. In this way, the liquid guiding body is not limited to a cellular material, and may alternatively be made of a non-cellular material such as glass or a metal.

When the first liquid storage piece 421 is provided in the first liquid storage cavity 42, the liquid suction capability of the first liquid guiding body 431 is greater than the liquid suction capability of the liquid storage piece, and the aerosol generating substrate can be better guided from the first liquid storage piece 421 having a lower liquid suction capability to the first liquid guiding body 431 having a higher liquid suction capability, and is transferred to the first heat generating body 432.

Similarly, when the second liquid storage piece 521 is provided in the second liquid storage cavity 52, the liquid suction capability of the second liquid guiding body 531 is greater than the liquid suction capability of the liquid storage piece, and the aerosol generating substrate can be better guided from the second liquid storage piece 521 having a lower liquid suction capability to the second liquid guiding body 531 having a higher liquid suction capability, and is transferred to the second heat generating body 532.

In an aspect, both the first atomization assembly 43 and the second atomization assembly 53 may be approximately barrel-shaped (for example, cylindrical) with two ends open. The first liquid guiding body 431 and the second liquid guiding body 531 are barrel-shaped. The first heat generating body 432 and the second heat generating body 532 may be respectively disposed on inner wall surfaces of the first liquid guiding body 431 and the second liquid guiding body 531.

Further, the first atomization assembly 43 and the second atomization assembly 53 may alternatively be disposed in the housing 10 in a coaxial manner. In an aspect, the arrangement manner of the first atomization assembly 43 and the second atomization assembly 53 in the housing 10 is not limited. For example, the first atomization assembly 43 and the second atomization assembly 53 may be at least partially disposed in parallel.

For example, the first atomization assembly 43 and the second atomization assembly 53 may alternatively use any known atomization assembly structure. For example, the first liquid guiding body 431 and/or the second liquid guiding body 531 is a bowl-shaped liquid guiding body, and the heat generating body is disposed on the side surface of the bowl-shaped liquid guiding body. Still for example, the first liquid guiding body 431 and/or the second liquid guiding body 531 is a rod-shaped liquid guiding body disposed in the transverse direction or the vertical direction, and the heat generating body is disposed on the outer surface of the rod-shaped liquid guiding body in a manner such as wrapping or painting. Still for example, the first liquid guiding body 431 and/or the second liquid guiding body 531 is a regular flat-shaped liquid guiding body (for example, a cuboid-shaped heat generating body) or an irregular flat-shaped liquid guiding body. At least one side of the liquid guiding body may be provided with a groove. Certainly, the liquid guiding body may alternatively not be provided with a groove. The heat generating body is disposed on at least one side of the liquid guiding body.

In an aspect, the first liquid storage and atomization module 40 may include a first liquid storage housing 41. The first liquid storage housing 41 is cylindrical and defines a first liquid storage cavity 42. The second liquid storage and atomization module 50 may include a second liquid storage housing 51. The second liquid storage housing 51 presents a barrel shape and defines a second liquid storage cavity 52.

A first vent pipe 45 may be further disposed in the first liquid storage housing 41 along the longitudinal direction. The first vent pipe 45 can have functions of ventilation and supporting the first atomization assembly 43. The inner wall surface of the first vent pipe 45 defines at least part of the first airflow channel 44. The first liquid storage cavity 42 is formed between the inner wall surface of the first liquid storage housing 41 and the outer wall surface of the first vent pipe 45. The first atomization assembly 43 is disposed in the first vent pipe 45, and at least one first liquid intake port, in liquid guiding communication with the first liquid storage cavity 42 and the first atomization assembly 43, is provided on the side wall of the first vent pipe 45.

A second vent pipe 55 may be disposed in the second liquid storage housing 51 along the longitudinal direction. The second vent pipe 55 can have functions of ventilation and supporting the second atomization assembly 53. The inner wall surface of the second vent pipe 55 defines at least part of the second airflow channel 54, and the second liquid storage cavity 52 is formed between the inner wall surface of the second liquid storage housing 51 and the outer wall surface of the second vent pipe 55. The second atomization assembly 53 is disposed in the second vent pipe 55, and at least one second liquid inlet, in liquid guiding communication with the second liquid storage cavity 52 and the second atomization assembly 53, is disposed on the side wall of the second vent pipe 55.

In an aspect, a bottom cover 46 may be disposed at the lower end of the first liquid storage housing 41, and is configured to cover an opening at the lower end of the first liquid storage housing 41. Further, the bottom cover 46 may be at least partially embedded in the opening at the lower end of the first liquid storage housing 41, and the bottom cover 46 may be made of an elastic sealing material such as silicon, to improve the sealing performance. A through hole 460 communicating the air intake vent 111 and the first airflow channel 44 is formed in the bottom cover 46.

A top cover 56 may be provided at the upper end of the second liquid storage housing 51, and is configured to cover an opening at the upper end of the second liquid storage housing 51. Further, the top cover 56 may be at least partially embedded in the opening at the lower end of the second liquid storage housing 51, and the top cover 56 may be made of an elastic sealing material such as silicon, to improve the sealing performance. A through hole 560 communicating the second airflow channel 54 and the air discharge vent 112 is formed in the top cover 56. An aerosol generated in the second airflow channel 54 only flows to the air discharge vent 112 through the through hole 560 and does not flow outward, so that no waste of the aerosol is caused.

In an aspect, the electronic atomization device 1 further includes an atomization seat 57 disposed in the housing 10. The atomization seat 57 is arranged between the first liquid storage housing 41 and the second liquid storage housing 51. The atomization seat 57 can cover the opening at the upper end of the first liquid storage housing 41 and the opening at the lower end of the second liquid storage housing 51, and seal and separate the first liquid storage cavity 42 from the second liquid storage cavity 52. The atomization seat 57 may be made of an elastic sealing material such as silicon. Part of the atomization seat 57 is embedded in the opening at the upper end of the first liquid storage housing 41 to be sealed to the opening at the upper end of the first liquid storage housing 41, and part of the atomization seat 57 is embedded in the opening at the lower end of the second liquid storage housing 51 to be sealed to the opening at the lower end of the second liquid storage housing 51. A communication hole 570 is formed in the atomization seat 57, so as to communicate the first airflow channel 44 and the second airflow channel 54. In this way, the aerosol generated in the first airflow channel 44 only enters the second airflow channel 54 through the communication hole 570, and does not flow outward, so that no waste of the aerosol is caused.

Further, to improve the air tightness of communication between the communication hole 570 and the first airflow channel 44, the lower end of the communication hole 570 and the upper end of the first airflow channel 44 may further be inserted into each other, to improve the air tightness. For example, the lower end of the communication hole 570 is inserted into the first airflow channel 44 in a sealing manner, that is, the outer wall surface of the lower end of the communication hole 570 is in sealing fit (for example, interference fit) with the inner wall surface of the upper end of the first airflow channel 44. Alternatively, the upper end of the first airflow channel 44 may be inserted into the communication hole 570 in a sealing manner.

Similarly, the upper end of the communication hole 570 and the lower end of the second airflow channel 54 may alternatively be inserted into each other, to improve the air tightness. For example, the upper end of the communication hole 570 is inserted into the second airflow channel 54 in a sealing manner. Alternatively, the lower end of the second airflow channel 54 may be inserted into the communication hole 570 in a sealing manner.
