The power supply assembly is electrically connected to the atomizer, and the power supply assembly is mainly configured to supply power to the atomizer and control operations such as on or off of the whole aerosol generating device, etc.

It should be understood by those skilled in the art that types of the aerosol generating device are not specifically limited in the embodiments of the present disclosure. For example, the aerosol generating device may be a medical atomization device, an air humidifier, or a device that requires using the atomizer, such as an electronic cigarette, etc.

An embodiment of the present disclosure provides an atomizer 10. With reference to FIG. 1 to FIG. 9, the atomizer 10 includes an oil storage bin 1 and an atomizing assembly 2. The oil storage bin 1 includes a housing assembly 11, a base assembly 12 and a first liquid inlet channel 15, the base assembly 12 and the housing assembly 11 define and form there-between a liquid storage cavity 13 configured to store an aerosol generating matrix. At least a portion of the base assembly 12 is movable in a first direction relative to the housing assembly 11. The atomizing assembly 2 is capable of being in fluid communication with the oil storage bin 1 through the first liquid inlet channel 15 during assembly of the atomizing assembly 2 and the oil storage bin 1, and the atomizing assembly 2 is capable of allowing the base assembly 12 to move in the first direction relative to the housing assembly 11.

The atomizer 10 is a device that converts liquid into a form of tiny droplets, is widely used in electronic cigarettes, medical spray devices, aromatherapy machines or other fields, and may emit the liquid in a form of mist through a specific working mechanism, which facilitates inhaling by the user, diffusion or other operations, to meet demands of different scenarios.

The oil storage bin 1 is a component of the atomizer 10 configured to store a to-be-atomized liquid (i.e., the aerosol generating matrix), and continuously provides liquid raw materials for an atomization process to ensure an uninterrupted atomization operation. The oil storage bin 1 may accommodate a sufficient amount of liquid to ensure a stable operation of the atomizer 10 in a period of time.

The housing assembly 11 is a part that constitutes an external frame structure of the oil storage bin 1, plays a role of protecting internal structures, accommodating other assemblies and defining an internal functional space, provides an overall mechanical strength for the oil storage bin 1, and reduces damage to internal fine components caused by external force. Furthermore, the housing assembly 11 may mold an external shape and profile of the oil storage bin 1 to meet aesthetic requirements of consumers.

The base assembly 12 is located at the bottom of the oil storage bin 1, and forms the oil storage bin 1 together with the housing assembly 11. On one hand, the base assembly 12 may define the liquid storage cavity 13 together with the housing assembly 11, and on the other hand, the base assembly 12 has functions of connecting to other components, transmitting the liquid, etc.

The first liquid inlet channel 15 is a channel structure provided on the oil storage bin 1, and plays a main role of acting as a passage through which the liquid flows, such that an aerosol generating matrix coming from the aerosol generating matrix in the liquid storage cavity 13 and flowing to the atomizing assembly 2 may be delivered smoothly.

Specific structures of the first liquid inlet channel 15 are not limited here. The first liquid inlet channel 15 usually has a tubular structure, and a diameter of the tube may be designed according to factors such as an atomization efficiency and an amount of stored liquids of the atomizer 10, etc.

Exemplarily, an inner wall of the first liquid inlet channel 15 may be made of a smooth stainless steel material, which is not only resistant to corrosion, but also may reduce a flow resistance of the liquid and a residue of the liquid.

In some embodiments, the first liquid inlet channel 15 may be designed in a spiral shape to increase a flow path of the liquid in the channel, such that the liquid is dispersed more uniformly when the liquid enters the liquid storage cavity 13, to avoid situations such as splashing of the liquid due to local impact, occurrence of bubbles or the like from affecting a subsequent atomization effect.

Exemplarily, a one-way valvular structure may be provided at an end of the first liquid inlet channel 15 close to the liquid storage cavity 13, to allow the liquid to flow in a direction toward the liquid storage cavity 13 only, prevent the liquid in the liquid storage cavity 13 from flowing back to the outside in some special situations (for example, the atomizer 10 is tilted and shaken), ensure stability of level of the liquid and purity of the liquid in the liquid storage cavity 13, and prevent external impurities from re-entering the liquid storage cavity 13 with backflow of the liquid.

A first accommodation cavity 121 is a space enclosed by interior of the housing assembly 11, and the first accommodation cavity 121 provides a place for arranging the base assembly 12 and other subsequent associated components.

The liquid storage cavity 13 is a cavity specially configured to store the to-be-atomized liquid, and is defined and formed by the base assembly 12 and the housing assembly 11 cooperating with each other, to ensure stable storage of the liquid, prevent leakage, and stably deliver the liquid to the atomizing assembly 2 as required.

A volume of the liquid storage cavity 13 is determined according to actual requirements and is not limited here. It may be understood that the volume of the liquid storage cavity 13 is determined together with a size of the first accommodation cavity 121 and an arrangement position of the base assembly 12.

The base assembly 12 and the housing assembly 11 cooperate with each other, and profiles and shapes of the base assembly 12 and the housing assembly 11 fit with each other to define the liquid storage cavity 13 together. Furthermore, an ability of the base assembly 12 moving in the first direction relative to the housing assembly 11 may change the volume of the liquid storage cavity 13, thereby changing pressure in the liquid storage cavity 13.

Exemplarily, the atomizing assembly 2 enables at least a portion of the base assembly 12 move in the first direction relative to the housing assembly 11, which may be a nested and slidable connection achieved in a form of a portion of the base assembly 12 extending into the first accommodation cavity 121, or may be a nested and slidable connection achieved in a form of a portion of the housing assembly 11 extending into the base assembly 12. Connection modes of relative movement between the base assembly 12 and the housing assembly 11 are specifically determined according to actual requirements.

In some embodiments, a slide rail or groove is provided on an inner wall and/or an outer wall of the housing assembly 11 in the first direction; correspondingly, an edge of the base assembly 12 are equipped with a slider or rib, and the slide rail or groove precisely fits with the slider or rib, to achieve smooth and accurate linear sliding of the base assembly 12, avoid occurrence of offset and seizing up during movement, and ensure accuracy of docking between the liquid storage cavity 13 and the atomizing assembly 2 after each displacement.

Exemplarily, elastic limiting blocks may also be added at two ends of the slide rail, to limit a movement range of the base assembly 12 and prevent structural damage and liquid leakage due to excessive displacement.

In some embodiments, after the base assembly 12 is moved a predetermined distance in the first direction, the housing assembly 11 prevents the atomizing assembly 2 from continuing to move in the first direction, and/or the housing assembly 11 prevents the base assembly 12 from continuing to move in the first direction.

In this way, after the volume of the liquid storage cavity 13 is reduced to a desired volume, the housing assembly 11 prevents the atomizing assembly 2 from continuing to move in the first direction, and/or the housing assembly 11 prevents the base assembly 12 from continuing to move in the first direction, thereby limiting the range of movement of the base assembly 12.

Exemplarily, on contact surfaces of the housing assembly 11 and the base assembly 12, a conventional sealing ring made of rubber may be provided around edges of the liquid storage cavity 13. It is also possible to use a multi-layer seal design, such as addition of a soft silicone sealing gasket that may adaptively deform to fill tiny gaps during movement of the base assembly 12.

In some situations, sealing greases may also be applied to frequently movable connection areas to reduce friction coefficients thereof, which not only assists smooth movement, but also further blocks liquid leakage.

In some embodiments, an ingenious linkage structure is designed. When the base assembly 12 moves in the first direction to a position where the liquid storage cavity 13 is fully communicated with the atomizing assembly 2, a micro switch is triggered, a switch signal is transmitted to a main control panel of the atomizer 10, and an indicator light is lit to prompt the user that the device is assembled in place. In some other embodiments, when filling an atomizing core 23 with oil completes, the indicator light may also prompt the user that the device may start operations. On the contrary, when the base assembly 12 moves back to an initial position to disconnect the liquid storage cavity 13 from the atomizing assembly 2, a signal is fed back again, and the main control panel may temporarily stop a portion of circuits from consuming energy, to enter a standby energy-saving mode.

Exemplarily, it may be a nested connection achieved in a form of a portion of the atomizing assembly 2 extending into the oil storage bin 1, or may be a nested connection achieved in a form of a portion of the oil storage bin 1 extending into the atomizing assembly 2. Connection modes between the atomizing assembly 2 and the oil storage bin 1 are specifically determined according to actual requirements.

Exemplarily, the oil storage bin 1 is non-detachably connected to the atomizing assembly 2 after their assembly completes once, thereby ensuring reliability of connection between the oil storage bin 1 and the atomizing assembly 2, and helping to reduce a risk of oil leakage.

In some embodiments, the oil storage bin 1 is detachably connected to the atomizing assembly 2. Specific structures of the detachable connection are not limited here. Exemplarily, small powerful magnets are embedded on corresponding contact surfaces of the atomizing assembly 2 and the oil storage bin 1 respectively, and magnetic poles of the magnets are disposed in an accurate matching manner. When the atomizing assembly 2 and the oil storage bin 1 are close to each other, the atomizing assembly 2 and the oil storage bin 1 may automatically, quickly and firmly adsorb and fit with each other with an acting force of magnetic attraction, to achieve their accurate alignment and connection; furthermore, in order to prevent accidental disconnection, a mechanical buckle structure may also be added as an auxiliary means, and the buckle is designed to unlock the atomizing assembly 2 from the oil storage bin 1 by pressing it lightly, which is convenient for the user to disassemble the atomizing assembly 2 from the oil storage bin 1.

Exemplarily, a unique plug-in interface is designed on the oil storage bin 1 and the atomizing assembly 2, and multiple elastic sheets are disposed in the interface. When the atomizing assembly 2 is inserted into the interface of the oil storage bin 1, the elastic sheets are squeezed and deformed, to clamp the inserted component tightly to provide a stable connection force. In some embodiments, a flexible sealing ring made of silicone is wrapped outside the interface, to ensure sealing performance during connection and prevent liquid leakage.

The first direction is not specifically limited in the present disclosure, and may be any direction. In order to facilitate descriptions, the first direction in the embodiment of the present disclosure is a direction shown in the drawings, that is, a first direction of the atomizer 10.

The atomizing assembly 2 is a core part of the atomizer 10, and its structures usually include an atomizing core 23, an electrode or other parts. The atomizing core 23 is a key part that acts on the liquid directly to atomize the liquid, is responsible for converting the liquid delivered from the oil storage bin 1 into mist particles, and achieves an atomization target by technical means such as ultrasonic oscillation, heating and evaporation of a heating wire, etc. The atomizing assembly 2 determines atomization effect and quality. The electrode is connected to the power supply assembly to obtain electric energy, and its performance and quality determine the atomization effect and quality directly.

Specific structures of fluid communication between the liquid storage cavity 13 and the atomizing assembly 2 are not limited here. The liquid storage cavity 13 is in fluid communication with and the atomizing assembly 2 after insertion and assembly of the atomizing assembly 2 complete, the aerosol generating matrix may be delivered to the atomizing core 23, and the atomizer 10 may operate normally.

In order to meet market demands or regulatory requirements, it needs to arrange an structure of the atomizer 10 configured to store the aerosol generating matrix and other structures of the atomizer 10 in detachable structures. As a result, when the atomizer 10 is used for the first time and assembly of the atomizer 10 completes, it needs to wait for a period of time, resulting in that the atomizer 10 may be used normally only when the aerosol generating matrix is delivered to the atomizing core 23. If waiting time is too short, the aerosol generating matrix has not reached the atomizing core 23, this easily results in dry-burning of the atomizing core 23, and a burnt smell may occur, which affects the user's experience.

The atomizing assembly 2 is capable of being in fluid communication with the oil storage bin 1 through the first liquid inlet channel 15 during assembly of the atomizing assembly 2 and the oil storage bin 1, here a portion of the first liquid inlet channel 15 may be in fluid communication with the atomizing assembly 2. Therefore, when the atomizing assembly 2 may further allow the base assembly 12 to move in the first direction relative to the housing assembly 11, the base assembly 12 may drive the housing assembly 11 to move in the first direction, a volume of the oil storage bin 1 is reduced, pressure in the oil storage bin 1 is increased, and the aerosol generating matrix in the oil storage bin 1 may flow to the atomizing core 23 of the atomizing assembly through the first liquid inlet channel 15. After assembly of the atomizing assembly 2 completes, the first liquid inlet channel 15 is fully in fluid communication with the atomizing assembly 2, to achieve a best communication effect.

In other words, during the assembly process of the atomizing assembly 2 and the oil storage bin 1, the oil storage bin 1 first establishes fluid communication with the atomizing assembly 2 via the first liquid inlet channel 15, after which the volume of the liquid storage cavity 13 is reduced.

According to the atomizer 10 provided in the embodiment of the present disclosure, the liquid storage cavity 13 configured to store the aerosol generating matrix is defined and formed by the base assembly 12 and the housing assembly 11. The base assembly 12 is disposed to be movable at least in the first direction relative to the housing assembly 11, then the oil storage bin 1 may be in fluid communication with the atomizing assembly 2 through the first liquid inlet channel 15 during assembly, and the base assembly 12 is driven to move through the atomizing assembly 2 to reduce a volume of the liquid storage cavity 13, thereby increasing pressure in the liquid storage cavity 13 to allow the aerosol generating matrix to be squeezed out of the liquid storage cavity 13 with an action of the pressure, increasing the speed of delivering the aerosol generating matrix to the atomizing core 23 and thus shortening the user's waiting time to use the atomizer. Furthermore, at least a portion of the atomizing assembly 2 is inserted into a plug-in channel 14, and may drive the base assembly 12 to move in the first direction relative to the housing assembly 11, such that extrusion of the aerosol generating matrix is achieved simultaneously with assembly of the atomizer 10, without additional operations, which simplifies operation processes and further improves the user's usage experience.

In some embodiments, with reference to FIGS. 1 to 9, the atomizer 10 includes an oil storage bin 1 and an atomizing assembly 2. The oil storage bin 1 includes a housing assembly 11, a first assembly, and a first liquid inlet channel 15. A liquid storage cavity 13 is defined between the first assembly and the housing assembly 11, and is configured to store an aerosol generating matrix. During the assembly process of the atomizing assembly 2 and the oil storage bin 1, the oil storage bin 1 first establishes fluid communication with the atomizing assembly 2 via the first liquid inlet channel 15, after which the volume of the liquid storage cavity 13 is reduced.

It should be noted that the first assembly may be the aforementioned base assembly 12 or another component, as long as it can cooperate with the housing assembly 11 to define the liquid storage cavity 13.

At least a portion of the first assembly is capable of moving relative to the housing assembly 11 along a first direction. The first direction may be the height direction of the atomizer 10 or a direction intersecting (e.g., perpendicular to) the height direction of the atomizer 10.

The specific position of the first assembly is not limited here. For example, the first assembly may be located at the bottom of the housing assembly 11, or at the side, top, or any other position of the housing assembly 11.

In some embodiments, with reference to FIG. 1 to FIG. 9, the base assembly 12 includes a base 122 and a valve assembly 16, the base 122 is provided with a plug-in channel 14 and the first liquid inlet channel 15, the valve assembly 16 is capable of sealing the first liquid inlet channel 15. At least a portion of the atomizing assembly 2 is capable of inserting into the plug-in channel 14 and driving the valve assembly 16 to move, such that the oil storage bin 1 is in fluid communication with the atomizing assembly 2 through the first liquid inlet channel 15.

As a main structure of the base assembly 12, the base 122 closely fits and cooperates with the housing assembly 11. The base 122 defines and forms key structures such as the plug-in channel 14, the first liquid inlet channel 15 or the like, provides a basic platform for integration of each component, and strongly ensures that layout of internal structures is reasonable and stable.

The plug-in channel 14 is a channel structure reserved in the base assembly 12 for other components to be inserted there-through. The plug-in channel 14 may play a role of guiding and positioning inserted components, establishing liquid or electrical connection or the like, to ensure accurate docking and cooperative operations of connected components.

Exemplarily, the atomizing assembly 2 may cooperate with the base assembly 12 in the plug-in channel 14, and after cooperation completes, an end of the first liquid inlet channel 15 is connected to the atomizing assembly 2, to achieve liquid-circulated communication between the first liquid inlet channel 15 and the atomizing assembly 2.

In some embodiments, conductive contacts are provided on contact surfaces of the plug-in channel 14 and the atomizing assembly 2, and after cooperation between the plug-in channel 14 and the atomizing assembly 2 completes, and the conductive contacts of the plug-in channel 14 and the atomizing assembly 2 are in contact to achieve electrical connection.

The valve assembly 16 is a key part of the base assembly 12, and the valve assembly 16 may be partially disposed in the plug-in channel 14. When the atomizing assembly 2 is inserted into the plug-in channel 14, the valve assembly 16 may also be in contact with the atomizing assembly 2, and movement of the atomizing assembly 2 drives movement of the valve assembly 16 to achieve a function of the valve assembly 16 sealing or opening the first liquid inlet channel 15.

Here, the valve assembly 16 may seal the first liquid inlet channel 15, which means that the valve assembly 16 may seal the first liquid inlet channel 15 or open the first liquid inlet channel 15.

The valve assembly 16 seals the first liquid inlet channel 15, which means that there is an overlapping area between the valve assembly 16 and the first liquid inlet channel 15, and the overlapping area may completely seal the first liquid inlet channel 15 and block movement of the aerosol generating matrix in the first liquid inlet channel 15. For example, a portion of structures of the valve assembly 16 may extend into the first liquid inlet channel 15, or a portion of structures of the valve assembly 16 may be disposed at a port of the first liquid inlet channel 15, and the aerosol generating matrix moves to the valve assembly 16 and is blocked by the valve assembly 16 from continuing to move, thereby achieving an effect of the valve assembly 16 intercepting the first liquid inlet channel 15.

When the valve assembly 16 is far away from the first liquid inlet channel 15, the overlapping area between the valve assembly 16 and the first liquid inlet channel 15 cannot completely seal the first liquid inlet channel 15, or there is no overlapping area between the valve assembly 16 and the first liquid inlet channel 15, and the aerosol generating matrix may pass through the valve assembly 16 from a gap between the valve assembly 16 and the first liquid inlet channel 15, to continue to move in the first liquid inlet channel 15, thereby achieving a function of the valve assembly 16 opening the first liquid inlet channel 15.

The oil storage bin 1 is provided with the first liquid inlet channel 15 and the valve assembly 16, and the first liquid inlet channel 15 acts as a bridge for circulation of the liquid between the liquid storage cavity 13 and the atomizing assembly 2, such that liquid may enter and exit the liquid storage cavity 13 at an appropriate time. Furthermore, the valve assembly 16 may selectively allow the first liquid inlet channel 15 to be in an opening or closing state according to actual requirements, to accurately control flow of the liquid. When the atomizing assembly 2 is inserted into the plug-in channel 14 of the base assembly 12 of the oil storage bin 1, a corresponding linkage action may be generated to drive the valve assembly 16 to open the first liquid inlet channel 15, such that fluid communication between the liquid storage cavity 13 and the atomizing assembly 2 may be achieved, thereby preparing a liquid delivery passage for a subsequent atomization process. In this way, it is beneficial to close the liquid storage cavity 13 when the atomizer 10 is disassembled and not used, to prevent liquid leakage; open the liquid storage cavity 13 when the atomizer 10 is assembled for use, to supply the liquid.

In some embodiments, with reference to FIG. 1 to FIG. 6, at least a portion of the valve assembly 16 is movably disposed in the plug-in channel 14. The first liquid inlet channel 15 penetrates a side wall of the plug-in channel 14.

Here, the first liquid inlet channel 15 traverses the plug-in channel 14 in a penetration manner, and the atomizing assembly 2 is inserted into the plug-in channel 14 to drive the valve assembly 16 to move in the plug-in channel 14. Such layout allows a liquid transportation route to intersect with an insertion path of the atomizing assembly 2. Furthermore, the valve assembly 16 is disposed in the plug-in channel 14 in a movable manner, such that when the atomizing assembly 2 is inserted into the plug-in channel 14, the valve assembly 16 may be triggered to generate displacement by means of a mechanical force generated by the insertion action or other set linkage mechanisms, and then the first liquid inlet channel 15 may be accurately opened, to open a liquid delivery channel between the liquid storage cavity 13 and the atomizing assembly 2, which improves accuracy of controlling an atomizing operation process, improves efficiency of using the atomizer 10, reduces the user's operation difficulty, thereby improving the user's experience.

In some embodiments, with reference to FIG. 8 and FIG. 9, at least a portion of the valve assembly 16 is movably disposed in the plug-in channel 14. The first liquid inlet channel 15 penetrates the base 122 in the first direction.

Here, the first liquid inlet channel 15 directly penetrates the base 122 along a predetermined first direction, and when the atomizing assembly 2 is inserted into the first liquid inlet channel 15, the valve assembly 16 may be driven to move in the first liquid inlet channel 15. Such layout allows a liquid transportation route to intersect with an insertion path of the atomizing assembly 2 ingeniously. Furthermore, the valve assembly 16 is disposed in the first liquid inlet channel 15 in a flexibly movable manner, such that when the atomizing assembly 2 is inserted, the valve assembly 16 may be accurately triggered to generate displacement by means of a mechanical force generated by the insertion action or other set linkage mechanisms, and then the first liquid inlet channel 15 may be accurately opened, to open a liquid delivery channel between the liquid storage cavity 13 and the atomizing assembly 2, which improves accuracy of controlling an atomizing operation process, improves efficiency of using the atomizer 10, reduces the user's operation difficulty, thereby improving the user's experience.

It should be noted that in the embodiment in which the first liquid inlet channel 15 penetrates the base 122 in the first direction, with reference to FIG. 9, the first liquid inlet channel 15 is not only a liquid inlet channel to achieve a function of inlet of the liquid, but also a portion of the plug-in channel 14 to accommodate the atomizing assembly 2. The atomizing assembly 2 may be inserted into the plug-in channel 14 (i.e., the first liquid inlet channel 15), at least a portion of the valve assembly 16 is movably disposed in the plug-in channel 14 (i.e., the first liquid inlet channel 15), and the atomizing assembly 2 drives the valve assembly 16 to move in the plug-in channel 14 (i.e., the first liquid inlet channel 15).

In some embodiments, the first liquid inlet channel 15 may be completely disposed on the base 122. In some other embodiments, the first liquid inlet channel 15 is partially disposed on the base 122 and partially disposed on the atomizing assembly 2. After assembly and fitting of the atomizer 10 complete, the base 122 is in contact with the atomizing assembly 2 to define and form the first liquid inlet channel 15 together.

In some embodiments, with reference to FIG. 1 to FIG. 6, the valve assembly 16 includes a first valve body 161, a circumferential side wall of the first valve body 161 slidably cooperates with the side wall of the plug-in channel 14, and at least the portion of the atomizing assembly 2 abuts against the first valve body 161.

In some embodiments, at least a portion of the atomizing assembly 2 is inserted into the first valve body 161.

The first valve body 161 is a structural component in the valve assembly 16, and the first valve body 161 is responsible for controlling a liquid or gas passage, and has an important responsibility of cooperating with operations of other components. Here, the first valve body 161, that is, the above portion of structures of the valve assembly 16 may extend into the first liquid inlet channel 15, or a portion of structures of the valve assembly 16 may be disposed at a port of the first liquid inlet channel 15.

Exemplarily, the first valve body 161 is sleeve-shaped, that is, its outer shape is similar to a hollow cylinder, in a specific tubular structure form. With the sleeve-shaped structure, it is beneficial to achieve nesting of the first valve body 161 with the plug-in channel 14, to form a slidable cooperation relationship; furthermore, it is also beneficial for the first valve body 161 to accommodate and guide insertion of the atomizing assembly 2, thereby driving movement of the first valve body 161.

The circumferential side wall refers to a portion of an outer wall surrounding the first valve body 161. This portion of the side wall directly participates in mechanical cooperation with the plug-in channel 14, and is a key contact surface to achieve functions such as relative movement, sealing, etc. The side wall usually has a specific machining accuracy requirement, to ensure good fit with associated components.

Here, since the first liquid inlet channel 15 penetrates the side wall of the plug-in channel 14, the circumferential side wall of the first valve body 161 may achieve functions of opening and closing the first liquid inlet channel 15 in a process of slidable cooperation between the circumferential side wall of the first valve body 161 and the side wall of the plug-in channel 14. Specifically, since the first liquid inlet channel 15 penetrates the side wall of the plug-in channel 14, that is, the first liquid inlet channel 15 has a port on the side wall of the plug-in channel 14, the circumferential side wall of the first valve body 161 may shield or avoid this port in the process of slidable cooperation between the circumferential side wall of the first valve body 161 and the side wall of the plug-in channel 14. When the circumferential side wall of the first valve body 161 shields this port, the aerosol generating matrix is blocked by the circumferential side wall of the first valve body 161 and cannot flow. When the circumferential side wall of the first valve body 161 avoids this port, the aerosol generating matrix may flow out of this port, and since the atomizing core 23 of the atomizing assembly 2 may extend into the plug-in channel 14, the aerosol generating matrix may be in contact with the atomizing core 23 in the plug-in channel 14, to achieve fluid communication between the atomizing assembly 2 and the first liquid inlet channel 15.

Specific materials of the first valve body 161 are not limited here. Exemplarily, materials of the first valve body 161 mainly select and use materials that are wear-resistant, corrosion-resistant and have high mechanical strength, such as stainless steel, engineering plastics or the like, to ensure a long-term stable operation.

In some embodiments, multiple guide rail grooves parallel to each other are added to the side wall of the plug-in channel 14 in an axial direction, a convex slider is provided at a corresponding position of the circumferential side wall of the first valve body 161, and the slider is accurately embedded in the grooves, such that a direction when the slider slidably cooperates with the grooves is more accurate, thereby completely eradicating a risk of self-rotation and skew of the valve body. An elastic buffer block is disposed at each end of each guide rail groove, and when the valve body slides to a limit position, the buffer block absorbs an impact force, to prevent hard collision from damaging components.

Exemplarily, the first valve body 161 is designed in a sleeve shape, is disposed in the plug-in channel 14, and is flexibly movable by using a slidable cooperation relationship between the circumferential side wall of the first valve body 161 and the side wall of the plug-in channel 14. Furthermore, at least a portion of the atomizing assembly 2 is inserted into the first valve body 161, such layout allows the insertion action of the atomizing assembly 2 to generate a linkage effect with the first valve body 161, and movement of the atomizing assembly 2 may drive movement of the first valve body 161, thereby accurately controlling opening and closing of the first liquid inlet channel 15.

In some embodiments, a connection structure such as a buckle or the like, is provided at a contact position between the first valve body 161 and the atomizing assembly 2.

The valve assembly 16 and the atomizing assembly 2 are connected via a connection structure. The atomizing assembly 2 pushes the valve assembly 16 away from its initial position, such the valve assembly 16 moves aside from the first liquid inlet channel 15.

When the atomization assembly 2 is detached, driven by the connection structure, the valve assembly 16 moves together with the atomization assembly 2 back to its initial position.

After at least a portion of the atomizing assembly 2 is inserted into the first valve body 161, the first valve body 161 is connected to the atomizing assembly 2, the atomizing assembly 2 pushes the first valve body 161 away from its initial position, and the first valve body 161 avoids the port of the first liquid inlet channel 15 on the side wall of the plug-in channel 14, to achieve fluid communication between the atomizing assembly 2 and the first liquid inlet channel 15.

When the atomizing assembly 2 is drawn out, the first valve body 161 moves to the initial position along with the atomizing assembly 2 with drive of the connection structure, and the first valve body 161 shields and avoids the port of the first liquid inlet channel 15 on the side wall of the plug-in channel 14, to achieve sealing.

In some embodiments, a blocking structure is provided on the plug-in channel 14, and the blocking structure limits after the atomizing assembly 2 drives the first valve body 161 to move to the initial position when the atomizing assembly 2 is drawn out, to prevent the atomizing assembly 2 from continuing to drive the first valve body 161 away from the initial position.

In some embodiments, with respect to the connection structure between the atomizing assembly 2 and the first valve body 161, when resistance provided by the blocking structure is large enough, the connection relationship between the atomizing assembly 2 and the first valve body 161 may be removed.

In some embodiments, with reference to FIG. 4 to FIG. 6, the valve assembly 16 includes a first elastic member 162, an end of the first elastic member 162 abuts against the housing assembly 11 or the base 12, and another end of the first elastic member 162 abuts against the first valve body 161. The atomizing assembly 2 is inserted into the plug-in channel 14 and drives the first valve body 161 to open the first liquid inlet channel 15, and the first elastic member 162 is elastically deformed.

The first elastic member 162 is a key component in the valve assembly 16, has an ability of elastic deformation, may change its own shape with an action of external force, and may restore to its initial shape when the external force disappears. These characteristics are used to achieve functions of providing an elastic force, resetting, assisting movement of components or the like in the structure.

Specific types of the first elastic member 162 are not limited here, and for example, the first elastic member 162 may be a spring, an elastic sheet, etc.

Exemplarily, if a spring is selected as the first elastic member 162, the spring may be designed as a diameter-variable structure, and diameters of the spring close to portions where two ends are in contact with the housing assembly 11 or the base 122 and the first valve body 161 may be increased appropriately, such that contact areas may be increased, force of the spring may be more uniform, and wear caused by excessive local pressure may be reduced.

Exemplarily, some small buffer strips made of rubber may be provided between spirals of the spring, and when the spring is compressed or deformed by tension, the strips made of rubber may play a buffer role, to further reduce vibration and noise, and also help to improve an overall stability of the spring.

Exemplarily, a concave mounting groove may be designed at a position where the housing assembly 11 or the base 122 abuts against the first elastic member 162, an inner wall of the mounting groove is inlaid with a wear-resistant pad made of nylon, and an end of the first elastic member 162 is embedded in the mounting groove and closely fits with the pad made of nylon. In this way, it may not only ensure reliable positioning, but also reduce a friction coefficient in a process of relative motion there-between (for example, when the elastic member expands and contracts) and reduce wear.

Exemplarily, a guide post is provided at a corresponding position where the first valve body 161 is connected to the first elastic member 162, the guide post passes through a central hole of the first elastic member 162, and an outer diameter of the guide post cooperates with an inner diameter of the central hole of the elastic member with a small gap, such that the first elastic member 162 accurately moves in a direction of the guide post during expansion and contraction, to avoid occurrence of deflection, distortion or other situations. Furthermore, a limiting projection is provided at each end of the guide post, to prevent the first elastic member 162 from separating from the guide post when the first elastic member 162 is excessively stressed.

An end of the first elastic member 162 in the valve assembly 16 abuts against the housing assembly 11 or the base 122, and another end of the first elastic member 162 abuts against the first valve body 161, to form a mechanically associated structure. When the atomizing assembly 2 is inserted into the plug-in channel 14, a driving force received by the atomizing assembly 2 is transmitted to the first valve body 161 in contact with the atomizing assembly 2, then the first valve body 161 overcomes the elastic force of the first elastic member 162 and thus moves, while the first liquid inlet channel 15 is opened, such that the liquid may flow to the atomizing assembly 2 to atomize the liquid, and the first elastic member 162 is elastically deformed correspondingly in this process.

Furthermore, the atomizing assembly 2 pushes the first valve body 161 away from its initial position, and the first valve body 161 avoids the port of the first liquid inlet channel 15 on the side wall of the plug-in channel 14, to achieve fluid communication between the atomizing assembly 2 and the first liquid inlet channel 15.

In some embodiments, the atomizing assembly 2 is separated from the plug-in channel 14, the first elastic member 162 restores from elastic deformation, and the first valve body 161 moves with an action of an elastic force of the first elastic member 162 to seal the first liquid inlet channel 15.

Here, the atomizing assembly 2 has a detachable structure. When the atomizing assembly 2 is pulled out of the plug-in channel 14, external force applied to the first valve body 161 disappears, the first elastic member 162 generates the elastic force by its own characteristics of restoring elastic deformation to push the first valve body 161 back to its initial position, and the first valve body 161 shields and avoids the port of the first liquid inlet channel 15 on the side wall of the plug-in channel 14 to seal the first liquid inlet channel 15 and prevent the liquid from continuing to flow. In this way, automatic sealing control of the liquid passage based on actions of inserting and pulling the atomizing assembly 2 is achieved.

Arrangement of the first elastic member 162 enables the first valve body 161 to be reliably reset and seal the first liquid inlet channel 15 after the atomizing assembly 2 is separated, thereby effectively preventing leakage of the liquid in the liquid storage cavity 13 in a non-atomization state, maintaining an amount and purity of the internal liquid, avoiding damage to other components or affecting the atomization effect due to liquid leakage, and improving overall reliability and stability of the atomizer 10.

In some embodiments, the valve assembly 16 includes a sealing part 163, which can be in close contact with the first liquid inlet channel 15 to seal the first liquid inlet channel 15.

In some embodiments, the atomizing assembly 2 is inserted into the first liquid inlet channel 15, pushing the sealing part 163 away from its initial position. The sealing part 163 to move aside from the first liquid inlet channel 15, thereby establishing fluid communication between the atomizing assembly 2 and the first liquid inlet channel 15.

In some embodiments, with reference to FIG. 7 to FIG. 9, the valve assembly 16 includes a sealing part 163 and a second elastic member 164, an end of the second elastic member 164 abuts against the housing assembly 11 or the base 122, and another end of the second elastic member 164 abuts against the sealing part 163. The atomizing assembly 2 is inserted into the first liquid inlet channel 15 and drives the sealing part 163 to open the first liquid inlet channel 15, and the second elastic member 164 is elastically deformed.

The sealing part 163 is a part of the valve assembly 16 configured to achieve a sealing function, and the sealing part 163 may be in close contact with the first liquid inlet channel 15, to block a passage of the liquid when it is unnecessary to flow, prevent leakage, and ensure good sealing performance of internal systems of the atomizer 10. Here, the sealing part 163, that is, the above portion of structures of the valve assembly 16 may extend into the first liquid inlet channel 15, or a portion of structures of the valve assembly 16 may be disposed at the port of the first liquid inlet channel 15.

Specific structures of the sealing part 163 are not limited here, and for example, the sealing part 163 may be a plug made of rubber, a pad made of silicone or the like, or a specially shaped component with a fitting surface.

The second elastic member 164 is a key component in the valve assembly 16, has an ability of elastic deformation, may change its own shape with an action of external force, and may restore to its initial shape when the external force disappears. These characteristics are used to achieve functions of providing an elastic force, resetting, assisting movement of components or the like in the structure.

Specific types of the second elastic member 164 are not limited here, and for example, the second elastic member 164 may be a spring, an elastic sheet, etc.

Two ends of the second elastic member 164 in the valve assembly 16 abut against the housing assembly 11 or the base 122 and the sealing part 163 respectively, to form a mechanically associated structure. When the atomizing assembly 2 is inserted into the first liquid inlet channel 15, a certain mechanical acting force may be generated, and this force is transmitted to the sealing part 163, then the sealing part 163 overcomes the elastic force of the second elastic member 164 and thus moves to open the first liquid inlet channel 15, such that the liquid may flow to the atomizing assembly 2 to atomize the liquid, and the second elastic member 164 is elastically deformed correspondingly in this process.

Furthermore, the atomizing assembly 2 pushes the sealing part 163 away from its initial position, and the sealing part 163 avoids the first liquid inlet channel 15, to achieve fluid communication between the atomizing assembly 2 and the first liquid inlet channel 15.

In some embodiments, the atomizing assembly 2 is separated from the first liquid inlet channel 15, the second elastic member 164 restores from elastic deformation, and the sealing part 163 moves with an action of an elastic force of the second elastic member 164 to seal the first liquid inlet channel 15.

Here, the atomizing assembly 2 has a detachable structure. When the atomizing assembly 2 is pulled out of the first liquid inlet channel 15, external force applied to the sealing part 163 disappears, the second elastic member 164 generates the elastic force by its own characteristics of restoring elastic deformation to push the sealing part 163 back to its initial position, and the sealing part 163 extends into the first liquid inlet channel 15 to block the first liquid inlet channel 15, thereby sealing the first liquid inlet channel 15 and preventing the liquid from continuing to flow. In this way, automatic sealing control of opening and closing states of the first liquid inlet channel 15 based on actions of inserting and pulling the atomizing assembly 2 is achieved.

With cooperation of the second elastic member 164, the sealing part 163 may well ensure a sealing state of the first liquid inlet channel 15 after the atomizing assembly 2 is pulled out, thereby effectively preventing leakage of the liquid in the liquid storage cavity 13 in the non-atomization state, maintaining an amount and purity of the internal liquid, avoiding damage to other components or affecting the atomization effect due to liquid leakage, and improving overall reliability and stability of the atomizer 10.

In some embodiments, with reference to FIG. 1 to FIG. 9, the housing assembly 11 and the atomizing assembly 2 jointly define and form a gas outlet channel 3. The gas outlet channel 3 is a channel structure specially configured to deliver aerosols formed after atomization, its core role is to allow the aerosols to smoothly reach an area accessible to the user from a place where they are generated, ensuring that small particles generated by atomization may be efficiently discharged in order, creating a good conditions for the user to inhale and diffuse the aerosols.

In some embodiments, the housing assembly 11 is provided with a gas outlet communicated with the plug-in channel 14, and the atomizing assembly 2 is provided with a first gas outlet sub-channel. When the atomizing assembly 2 is inserted into the plug-in channel 14, the gas outlet is communicated with the first gas outlet sub-channel, and the gas outlet and the first gas outlet sub-channel define and form the gas outlet channel 3 of the atomizer 10 together.

In some embodiments, the atomizing assembly 2, the valve assembly 16 and the housing assembly 11 jointly define and form a gas outlet channel 3.

Exemplarily, the housing assembly 11 is provided with a gas outlet communicated with the plug-in channel 14, the valve assembly 16 is provided with a second accommodation cavity, and the atomizing assembly 2 may be inserted into the second accommodation cavity. A second gas outlet sub-channel communicated with the second accommodation cavity is provided at a side of the valve assembly 16 close to the gas outlet. When the atomizing assembly 2 is inserted into the second accommodation cavity, the atomizing assembly 2 drives the first gas outlet sub-channel and the second gas outlet sub-channel to sequentially communicate with the gas outlet, and the first gas outlet sub-channel, the second gas outlet sub-channel and the gas outlet define and form the gas outlet channel 3 together.

The housing assembly 11 and the atomizing assembly 2 cooperate with each other, and after assembly of the atomizer 10 completes, a specific space is reserved and defined between the housing assembly 11 and the atomizing assembly 2, to form the gas outlet channel 3 together. When the atomizing assembly 2 atomizes the liquid into tiny aerosol particles, these particles flow outward along the gas outlet channel 33 defined by the housing assembly 11 and the atomizing assembly 2 together, and are accurately guided to a position where the user inhales and uses, to ensure that atomization results may be utilized effectively.

In an implementation, with reference to FIG. 1 to FIG. 9, the atomizing assembly 2 includes an atomizing seat 21, a liquid storage member 22 and an atomizing core 23, the liquid storage member 22 is sandwiched between the atomizing seat 21 and the atomizing core 23, the atomizing seat 21 is provided with a second liquid inlet channel 211, and the first liquid inlet channel 15 is capable of being in fluid communication with the liquid storage member 22 through the second liquid inlet channel 211.

The atomizing seat 21 is a basic support and structural connection component in the atomizing assembly 2, and plays a role of providing stable support for other parts.

The atomizing seat 21 is usually made of materials having hard textures and stable chemical property, such as engineering plastics and aluminum alloys. The atomizing seat 21 needs to withstand a certain pressure and resist erosion of the internal liquid, to maintain structural integrity and functional stability.

The liquid storage member 22 is a component of the atomizer 10 mainly configured to store the to-be-atomized liquid, the liquid storage member 22 is in contact with the atomizing core 23 and may directly supply the liquid to the atomizing core 23, and a generation amount of aerosols is controlled by controlling an amount of the aerosol generating matrix delivered to the atomizing core 23.

Specific materials of the liquid storage member 22 are not limited here. The liquid storage member 22 includes any suitable material capable of transporting a liquid form of aerosol generating matrix toward the atomizer 10 and a combination of multiple materials, and the liquid storage member 22 should play a capillary force role, to be capable of generating a capillary force to adsorb the aerosol forming matrix. The liquid storage member 22 may be made of a capillary material.

Specific types of the capillary material are not limited here. For example, the capillary material may include a sponge or foam material, a ceramic or graphite-based material in a form of fibers or sintered powders, a foamed metal or plastic material, a fibrous material (for example, made of as-spun or press-spun fibers (such as cellulose acetate fibers, polyester fibers, bonded polyolefin fibers, polyethylene fibers, polyester fibers or polypropylene fibers, nylon fibers)), or a ceramic.

The capillary material is provided with a capillary tube, and the capillary tube may play a role of any suitable capillary tube, to be used with physical properties of different liquids.

The capillary material may include a material that is porous itself, for example a ceramic material such as alumina (corundum). Alternatively, the porous material may include a material with multiple pores manufactured to allow migration of the liquid form of aerosol forming matrix to the atomization device. The porous material may include a hydrophilic material, to improve distribution and diffusion of the liquid form of aerosol forming matrix.

The porous material may have any suitable porosity to be used with physical properties of different liquids.

The liquid storage member 22 may also have other materials with capillary channels, which may be other materials with micropores or microgrooves opened thereon to have capillary acting force, such as plastics, stainless steel, glass, silica gel, etc.

The second liquid inlet channel 211 is a liquid circulation path opened on the atomizing seat 21, and the second liquid inlet channel 211 is communicated with the first liquid inlet channel 15 and is responsible for transporting the aerosol generating matrix, to ensure that the aerosol generating matrix reaches the liquid storage member 22 smoothly.

The atomizing assembly 2 includes three main components, i.e., the atomizing seat 21, the liquid storage member 22 and the atomizing core 23, and the liquid storage member 22 is sandwiched between the atomizing seat 21 and the atomizing core 23, such that an overall structure of the atomizing assembly 2 is more compact. The atomizing seat 21 is provided with the second liquid inlet channel 211, and the aerosol generating matrix in the first liquid inlet channel 15 may flow into the liquid storage member 22 through the second liquid inlet channel 211, to achieve efficient allocation and delivery of the liquid, supply the liquid to the atomizing core 23 stably, and ensure that atomization operations are carried out.

In an implementation, with reference to FIG. 1 to FIG. 9, the liquid storage member 22 includes a first sub-member 221 and a second sub-member 222 sequentially disposed in a height direction of the atomizer 10, the second sub-member 222 is far away from the atomizing core 23, and a capillary force of the first sub-member 221 is greater than a capillary force of the second sub-member 222.

The capillary force is an acting force related to surface tension of the liquid occurred in the capillary tube or porous medium. Simply speaking, when the liquid comes into contact with a solid surface, since a cohesive force between molecules of the liquid is different from an adhesive force between the liquid and molecules of the solid surface, a force that allows the liquid to rise or fall in a small space (such as the capillary tube) may be generated, which is the capillary force. A magnitude of the capillary force is related to pore sizes of capillary pores formed by the material, density of the material, and type of the material itself.

The liquid storage member 22 is divided into the first sub-member 221 and the second sub-member 222 sequentially disposed in the first direction of the atomizer 10. Since the capillary force of the first sub-member 221 is greater than the capillary force of the second sub-member 222, flow of the aerosol generating matrix in the liquid storage member 22 exhibits a unique law, and the aerosol generating matrix may preferentially fill and flow through the first sub-member 221, to accurately match a high liquid supply requirement in an area close to the atomizing core 23.

The second sub-member 222 has a poor adsorption force to the aerosol generating matrix due to its relatively small capillary force and characteristics of its position. When reserves of the aerosol generating matrix on the first sub-member 221 are insufficient, the second sub-member 222 does not struggle with the first sub-member 221 for the aerosol generating matrix, instead, gives priority to ensuring that the aerosol generating matrix adsorbed by the first sub-member 221 is sufficient, thereby meeting requirements of the atomizing core 23 on the aerosol generating matrix.

When there is too much aerosol generating matrix on the first sub-member 221, the second sub-member 222 may absorb the excess aerosol generating matrix, thereby adjusting and controlling a content of the aerosol generating matrix on the first sub-member 221, such that the aerosol generating matrix is in a suitable suction range, to ensure a suction effect effectively and improve the user's experience.

The first sub-member 221 and the second sub-member 222 are subdivided structures of the liquid storage member 22 and are distributed in the first direction, such that the liquid storage member 22 may be disposed into structures with different capillary forces in the first direction, to meet actual usage requirements.

It should be emphasized here that the liquid storage member 22 is usually made of liquid storage cotton, and with respect to the liquid storage cotton, the greater the density of the liquid storage cotton, the stronger the adsorption force of the liquid storage cotton to the aerosol generating matrix, and the greater the capillary force. That is, the density of the liquid storage cotton of the first sub-member 221 is greater than the density of the liquid storage cotton of the second sub-member 221, and the adsorption force of the first sub-member 221 to the aerosol generating matrix is greater than the adsorption force of the second sub-member 222 to the aerosol generating matrix.
