Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and in particular to an aerosol generation device. Background Technology

[0002] An aerosol generating device is a device capable of atomizing a liquid matrix to generate aerosols. An exemplary aerosol generating device exists, comprising an atomizing module, a pumping assembly, and a supply chamber for storing the liquid matrix. The atomizing module includes a storage chamber for storing the liquid matrix and an atomizing core for atomizing the liquid matrix. The pumping assembly provides power to propel the liquid matrix from the supply chamber into the storage chamber, replenishing the storage chamber with liquid matrix. However, during operation, the pumping assembly can cause pressure changes in the supply chamber, such as an increase in pressure. These pressure changes can restrict or hinder the operation of the pumping assembly, reducing the efficiency of delivering the liquid matrix from the supply chamber to the storage chamber, or preventing the delivery of the liquid matrix altogether. Utility Model Content

[0003] The purpose of this application is to provide an aerosol generating device that can avoid large changes in the gas pressure supplied to the first storage chamber, thereby affecting the pumping of the liquid matrix.

[0004] At least one embodiment of this application provides an aerosol generating apparatus, and the aerosol generating apparatus includes;

[0005] The storage module has a first storage chamber inside for storing the liquid matrix;

[0006] An atomizing module includes a second storage chamber for storing a liquid matrix and an atomizing core for atomizing the liquid matrix to generate an aerosol, wherein the first storage chamber and the second storage chamber have a first channel connecting the two.

[0007] A driving module is configured to drive a change in air pressure within the first storage cavity or the second storage cavity, thereby facilitating the introduction of a liquid matrix from the first storage cavity into the second storage cavity through the first channel; and

[0008] An air valve is engaged with the storage module and communicates with the first storage cavity. The air valve is configured to have a closed state and an open state, and in the open state, it allows air in the first storage cavity to be discharged to the outside.

[0009] As an example, the drive module and the second storage cavity have a second channel connecting them, and the drive module is also configured to extract gas from the second storage cavity through the second channel when the aerosol generating device is in the first posture, so that the gas pressure in the second storage cavity is lower than the gas pressure in the first storage cavity, thereby promoting the introduction of the liquid matrix in the first storage cavity into the second storage cavity through the first channel.

[0010] As an example, the drive module has a third channel connecting the two with the first storage cavity, and the second channel is connected to the third channel through the drive module, so that fluid can circulate between the first storage cavity and the second storage cavity through the first channel, the second channel and the third channel.

[0011] As an example, a first one-way valve is provided in the first channel, which is configured to open when the air pressure in the second storage chamber is lower than the air pressure in the first storage chamber, so as to allow fluid to flow unidirectionally from the first storage chamber to the second storage chamber through the first channel.

[0012] As an example, a second one-way valve is provided in the second channel, which is configured to open when the air pressure in the drive module is lower than the air pressure in the second storage chamber, so as to allow fluid to flow unidirectionally from the second storage chamber to the drive module through the second channel.

[0013] As an example, the drive module includes a piston and a pump body with an internal pump chamber;

[0014] The piston is configured to move relative to the pump body between a first position and a second position, wherein when moving from the first position to the second position, the pump chamber is connected to the first storage chamber and the air pressure in the pump chamber is greater than the air pressure in the first storage chamber, and when moving from the second position to the first position, the air pressure in the pump chamber is less than the air pressure in the second storage chamber, causing the second one-way valve to open so that the pump chamber is connected to the second storage chamber.

[0015] As an example, the drive module also includes an operating element linked to the piston, the operating element being configured to be operable to drive the piston from the first position to the second position.

[0016] As an example, when the aerosol generating device is in the second posture, then:

[0017] When the piston moves from the first position to the second position, the fluid in the pump chamber flows into the first storage chamber through the third channel, and the gas in the first storage chamber is introduced into the second storage chamber through the first channel;

[0018] When the piston moves from the second position to the first position, the liquid matrix in the second storage chamber flows into the pump chamber through the second channel.

[0019] As an example, the drive module is configured to extract liquid matrix from the second storage cavity through the second channel when the aerosol generating device is in the second posture, and to introduce at least a portion of the liquid matrix in the drive module into the first storage cavity through the third channel.

[0020] As an example, it also includes a suction nozzle, wherein the second storage cavity has a proximal end and a distal end disposed opposite to each other, and the suction nozzle is disposed near the proximal end of the second storage cavity;

[0021] The atomizing module includes a first flow guide hole and a second flow guide hole. The second storage cavity is connected to the first channel through the first flow guide hole and to the second channel through the second flow guide hole.

[0022] The second flow guide hole is disposed near the proximal end of the second storage cavity, such that the liquid matrix in the second storage cavity is submerged in the second flow guide hole when the aerosol generating device is in the second posture.

[0023] As an example, the atomizing module includes a holding tube disposed in the second storage cavity, the atomizing core being held in the holding tube, and a liquid guiding hole communicating between the second storage cavity and the atomizing core being provided on the wall of the holding tube. The liquid guiding hole is disposed near the far end of the second storage cavity to prevent the liquid guiding hole from being submerged by the liquid matrix in the second storage cavity when the aerosol generating device is in the second posture.

[0024] As an example, it also includes a first conduit for defining the first channel, the first conduit having a fluid inlet communicating with the first storage cavity to guide the liquid matrix in the first storage cavity into the first channel;

[0025] The first storage cavity has a proximal end and a distal end disposed opposite to each other, and the fluid inlet is disposed near the distal end of the first storage cavity to prevent the fluid inlet from being submerged by the liquid matrix in the first storage cavity when the aerosol generating device is in the second posture.

[0026] As an example, the air valve includes a first pressure relief port, a second pressure relief port, and a valve body movable between the first pressure relief port and the second pressure relief port;

[0027] The air valve is configured to connect to the outside in the open state to balance the air pressure in the first storage chamber with the ambient air pressure, and to isolate the first storage chamber from the outside when closed.

[0028] The second pressure relief port is configured to be open when the air valve is open and sealed by the valve body when the air valve is closed.

[0029] As an example, the first storage cavity has a proximal end and a distal end disposed opposite to each other, the air valve is disposed near the proximal end of the first storage cavity, and the valve body is configured to open the second pressure relief hole by its own gravity when the aerosol generating device is in a first posture, and to seal the second pressure relief hole at least by its own gravity when the aerosol generating device is in a second posture.

[0030] As an example, the air valve is configured to open when the aerosol generating device is in a first posture and close when the aerosol generating device is in a second posture.

[0031] As an example, the first pressure relief hole is disposed facing the first storage cavity, and the second pressure relief hole is disposed away from the first storage cavity. The air valve also includes a pressure relief pipe, and the valve body is movably disposed in the pressure relief pipe along the axial direction of the pressure relief pipe. There is a gap between the valve body and the inner wall of the pressure relief pipe, and the gap is configured to connect the first pressure relief hole and the second pressure relief hole when the air valve is open.

[0032] The pressure relief pipe is provided with a support member, which is configured to block the valve body when the aerosol generating device is in the first position, so as to prevent the valve body from sealing the first pressure relief hole.

[0033] As an example, the support member includes a plurality of spaced-apart support ribs; and / or

[0034] The support includes an elastic element disposed between the first pressure relief hole and the valve body.

[0035] As an example, it also includes a ventilation channel and a retaining wall that is at least partially disposed around the drive module, wherein the air valve, when open, connects the first storage cavity and the ventilation channel;

[0036] The ventilation channel is at least partially disposed between the drive module and the retaining wall.

[0037] As an example, the retaining wall has ventilation holes that connect the outside world and the ventilation channel.

[0038] As an example, the air valve automatically switches between an open and closed state in response to a deflection of the aerosol generating device's attitude.

[0039] Alternatively, the air valve may automatically switch between an open and closed state in response to changes in the pressure difference across the first storage cavity.

[0040] At least one embodiment of this application provides an aerosol generating apparatus, which includes: a storage module having a first storage cavity for storing a liquid matrix;

[0041] An atomizing module includes a second storage chamber for storing a liquid matrix and an atomizing core for atomizing the liquid matrix to generate an aerosol, wherein the first storage chamber and the second storage chamber have a first channel connecting them; and

[0042] A driving module is configured to drive a change in gas pressure within the first storage cavity or the second storage cavity, thereby facilitating the introduction of a liquid matrix from the first storage cavity into the second storage cavity through the first channel. A second channel connects the driving module and the second storage cavity. The aerosol generating device has a first posture and a second posture during use. When the aerosol generating device is in the first posture, the driving module can extract gas from the second storage cavity through the second channel, thereby facilitating the introduction of a liquid matrix from the first storage cavity into the second storage cavity through the first channel. When the aerosol generating device is in the second posture, the driving module can extract liquid matrix from the second storage cavity through the second channel and further introduce it into the first storage cavity.

[0043] The aerosol generating device provided in the above embodiments includes an air valve, a drive module, a storage module with a first storage cavity inside, and an atomizing module including a second storage cavity and an atomizing core. The first storage cavity and the second storage cavity are connected through a first channel. The drive module can drive the air pressure change in the first storage cavity or the second storage cavity, thereby promoting the liquid matrix in the first storage cavity to be introduced into the second storage cavity through the first channel. The air valve has a closed state and an open state, and when it is open, it allows the air in the first storage cavity to be discharged to the outside, thereby avoiding large changes in the air pressure supplied to the first storage cavity that would affect the delivery of the liquid matrix to the second storage cavity.

[0080] Please refer to Figures 1-3 This application provides an aerosol generating device 100, which includes a storage module 1, an atomizing module 2, and a driving module 3. The storage module 1 has a first storage cavity 11 for storing a liquid matrix. The atomizing module 2 includes a second storage cavity 21 for storing a liquid matrix and an atomizing core 22 for atomizing the liquid matrix to generate aerosol. The storage module 1 can be connected to the atomizing module 2. After connection, a first channel 1a connects the first storage cavity 11 and the second storage cavity 21. The driving module 3 provides power to replenish the liquid matrix from the first storage cavity 11 to the second storage cavity 21 through the first channel 1a, so that the atomizing core 22 can continue to work and the aerosol generating device 100 can continue to generate aerosol.

[0081] The liquid matrix is ​​liquid at room temperature. In some embodiments, the liquid matrix may comprise a liquid containing tobacco-containing substances with volatile tobacco aroma components. The liquid matrix may also comprise a liquid containing non-tobacco substances. The liquid matrix may comprise water, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures, etc. Fragrances may include, but are not limited to, areca nut extract, menthol, peppermint, spearmint oil, various fruit flavoring components, etc. Flavorings may contain ingredients that can provide the user with various fragrances or flavors. Vitamin mixtures may be mixtures containing at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but are not limited to.

[0082] In some embodiments, the atomizing core 22 includes a liquid absorption assembly and a heating element, wherein the liquid absorption assembly is used to guide the liquid matrix to the heating element, thereby enabling at least a portion of the liquid matrix in the liquid absorption assembly to atomize and generate an aerosol under the heat released by the heating element.

[0083] The liquid absorption assembly may include a porous body. The porous body can be a fiber, such as cotton fiber, polypropylene fiber, polyester fiber, or nylon fiber. The porous body can also be porous ceramic or porous metal; this application does not limit the structure and composition of the porous body.

[0084] In some embodiments, the atomizing core 22 includes an ultrasonic element capable of generating ultrasonic waves, which enables the atomizing core 22 to atomize a liquid matrix into an aerosol. Of course, the atomizing core 22 may also include other elements capable of atomizing a liquid matrix into an aerosol, such as a nozzle capable of turning the liquid matrix into a mist.

[0085] In some embodiments, the aerosol generating device 100 is an electrically operated aerosol generating device, whereby the atomizing core 22 requires electrical power to atomize the liquid matrix to generate aerosol. Furthermore, the aerosol generating device 100 also includes a power module 4, which provides electrical power to the atomizing core 22 to atomize the liquid matrix and generate aerosol. The power module 4 may include any suitable battery, such as a lithium battery, a disposable battery, or a rechargeable battery.

[0086] In some embodiments, the atomizing module 2 further includes a retaining tube 23, which can guide the aerosol generated by the atomizing liquid matrix by the atomizing core 22 to the air outlet of the atomizing module 2, so that the aerosol can flow out of the atomizing module 2 through the air outlet.

[0087] In some embodiments, at least a portion of the atomizing core 22 is disposed in the retaining tube 23. Further, the retaining tube 23 extends longitudinally within the second storage cavity 21. In other embodiments, the atomizing module further includes a compartment (not shown) in which the atomizing core is disposed. The compartment is in communication with the second storage cavity 21 via a liquid channel, allowing the liquid matrix in the second storage cavity 21 to be transferred to the atomizing core. The compartment is in fluid communication with the retaining tube, allowing the aerosol formed in the compartment to be discharged through the retaining tube.

[0088] In some embodiments, the atomizing module 2 further includes a liquid storage element (not shown), which has a large number of pores and is capable of adsorbing a large amount of liquid matrix. The liquid storage element is disposed in the storage cavity, and at least partially of the liquid matrix stored in the storage cavity is retained in the liquid storage element, thereby preventing the liquid matrix from leaking from the second storage cavity. The liquid storage element includes, but is not limited to, one of the following materials: cotton fiber, polypropylene fiber, polyester fiber, nylon fiber, porous ceramic material, polymer fiber, or various combinations of the above materials.

[0089] In some embodiments, the wall of the holding tube 23 is provided with a liquid guiding hole 231 that connects the second storage cavity 21 and the atomizing core 22. The liquid guiding hole 231 can guide the liquid matrix in the second storage cavity 21 to the atomizing core 22 for atomization to generate an aerosol. At least a portion of the atomizing core 22 may be disposed in the holding tube 23.

[0090] Furthermore, the retaining tube 23 is surrounded by the second storage cavity 21. The atomizing module 2 also includes a liquid-absorbing medium 24 disposed within the retaining tube 23. The atomizing core 22 is disposed inside the liquid-absorbing medium 24. The liquid-absorbing medium 24 is configured to absorb the liquid matrix in the second storage cavity 21 through the liquid guiding hole 231 and conduct at least a portion of the absorbed liquid matrix to the atomizing core 22 for atomization. The liquid-absorbing medium 24 can store the liquid matrix, thereby helping to prevent the atomizing core 22 from dry burning.

[0091] In some embodiments, reference may be made to Figure 1 The aerosol generating device 100 also includes a mouthpiece 5 having an air outlet 51, at least a portion of which can be held in the mouth by a user, and the mouthpiece 5 is used to introduce aerosols into the user's oral cavity.

[0092] Furthermore, the atomizing module 2 includes a nozzle 5, or the nozzle 5 of the aerosol generating device is disposed on the atomizing module 2. Even further, the nozzle 5 is integrally formed with the housing 25 of the atomizing module 2.

[0093] In some embodiments, reference may be made to Figure 1 and Figure 2 The drive module 3 and the second storage cavity 21 are connected by a second channel 2a, through which at least a portion of the fluid in the second storage cavity 21 flows into the drive module 3. The fluid is a flowable substance, such as a liquid or a gas.

[0094] In some embodiments, reference may be made to Figure 11 and Figure 12 The drive module 3 is configured to extract fluid from the second storage cavity 21 through the second channel 2a, thereby allowing the gas or liquid matrix of the second storage cavity 21 to be transferred to the drive module 3 through the second channel 2a.

[0095] For example, when the aerosol generating device 100 is in the first position, the drive module 3 is configured to extract gas from the second storage chamber 21 through the second channel 2a, so that the gas pressure in the second storage chamber 21 is lower than the gas pressure in the first storage chamber 11. Then, under this pressure difference, the first storage chamber 11 can automatically replenish the liquid matrix to the second storage chamber 21 through the first channel 1a. In other words, when the aerosol generating device 100 is in the first position, the drive module 3 extracts gas from the second storage chamber 21 to create a negative pressure in the second storage chamber 21 relative to the first storage chamber 11, and then the second storage chamber 21 automatically draws in the liquid matrix from the first storage chamber 11 through the first channel 1a. Figure 12 In the diagram, the thin arrow indicates the direction of gas flow.

[0096] Furthermore, the drive module 3 includes a suction mechanism that extracts gas from the second storage cavity 21 through the second channel 2a to reduce the gas pressure in the second storage cavity 21. The suction mechanism can be an electric suction mechanism or a manual suction mechanism, which can be operated by a user to evacuate gas from the second storage cavity 21.

[0097] If the air pressure in the second storage chamber 21 is too high, it can easily cause the liquid matrix in the second storage chamber 21 to leak at the position of the atomizing core 22. When replenishing the liquid matrix in the second storage chamber 21 by conventional means, it is usually necessary to monitor the mass of liquid matrix added to the second storage chamber 21 and the frequency of liquid pumping into the second storage chamber 21 with relatively high precision to prevent the air pressure inside the second storage chamber 21 from becoming too high due to excessive replenishment of liquid matrix. In some embodiments of this application, the drive module 3 extracts gas from the second storage cavity 21 through the second channel 2a to make the gas pressure in the second storage cavity 21 lower than the gas pressure in the first storage cavity 11. This allows the liquid matrix in the first storage cavity 11 to be automatically replenished into the second storage cavity 21 through the first channel 1a based on the pressure difference. When the pressure difference decreases to a certain extent or disappears, the replenishment of the liquid matrix in the first storage cavity 11 into the second storage cavity 21 can be automatically stopped. This prevents leakage of the liquid matrix in the second storage cavity 21 due to excessive liquid matrix or leakage due to excessive gas pressure. Moreover, there is no need to manually monitor the quality of the liquid matrix replenished from the first storage cavity 11 into the second storage cavity 21, or to use sensors, meters, controllers, etc. to monitor the quality of the liquid matrix replenished from the first storage cavity 11 into the second storage cavity 21.

[0098] In some embodiments, reference may be made to Figure 5 The atomizing module 2 includes a second flow guide hole 252 that connects to the second storage cavity 21 and a first flow guide hole 251 that connects to the second storage cavity 21.

[0099] The second storage cavity 21 can be connected to the first channel 1a through the first guide hole 251, or the second storage cavity 21 can be connected to the first storage cavity 11 through the first guide hole 251, thereby the first guide hole 251 can introduce the fluid in the first storage cavity 11 or the first channel 1a into the second storage cavity 21.

[0100] The second storage cavity 21 can be connected to the second channel 2a through the second flow guide hole 252, or the second storage cavity 21 can be connected to the drive module 3 through the second flow guide hole 252, thereby the second flow guide hole 252 can guide the fluid in the second storage cavity 21 into the second channel 2a or the drive module 3.

[0101] Furthermore, the aerosol generating device 100 also includes a second conduit 2b, in which at least a portion of the second channel 2a is defined, one end of the second conduit 2b being connected to the atomizing module 2 and the other end being connected to the driving module 3.

[0102] In some embodiments, at least a portion of the second channel 2a is generally U-shaped, such that the second channel 2a can store at least a portion of the liquid matrix flowing out of the second storage cavity 21 through the second guide hole 252, thereby allowing the second storage cavity 21 to have a slight negative pressure relative to the ambient air pressure, which helps prevent leakage of the liquid matrix in the second storage cavity 21. When at least a portion of the second channel 2a is generally U-shaped, at least a portion of the second conduit 2b is also U-shaped.

[0103] In some embodiments, a portion of the second conduit 2b is located within the first storage cavity 11, and consequently, a portion of the second channel 2a is located within the first storage cavity 11. And / or, a portion of the second conduit 2b passes through the first storage cavity 11, thereby allowing a portion of the second channel 2a to pass through the first storage cavity 11.

[0104] In some embodiments, the second conduit 2b includes a first portion 2b1 and a second portion 2b2. The first portion 2b1 is connected to the atomizing module 2 and extends outside the storage module 1. The second portion 2b2 is connected to the driving module 3. The first portion 2b1 and the second portion 2b2 can be interconnected by assembly, or the first portion 2b1 and the second portion 2b2 can be integrally formed. At least a portion of the second portion 2b2 is disposed in the first storage cavity 11 of the storage module 1, and at least a portion of the second portion 2b2 is substantially U-shaped.

[0105] In some embodiments, the aerosol generating apparatus 100 further includes a first conduit 1b, at least partially defined in the first channel 1a, and a fluid inlet 1b3 is provided on the first conduit 1b, the fluid inlet 1b3 communicating with the first storage cavity 11 to guide the liquid matrix in the first storage cavity 11 into the first channel 1a.

[0106] In some embodiments, one end of the first conduit 1b is connected to the atomizing module 2, and the other end is connected to the storage module 1.

[0107] In some embodiments, the first conduit 1b includes a third portion 1b1 and a fourth portion 1b2. The third portion 1b1 is connected to the atomizing module 2 and extends outside the storage module 1. At least a portion of the fourth portion 1b2 may be disposed in the first storage cavity 11 of the storage module 1. The third portion 1b1 and the fourth portion 1b2 may be interconnected by assembly, or they may be integrally formed. A fluid inlet 1b3 is formed on the fourth portion 1b2.

[0108] In some embodiments, reference may be made to Figure 7 The aerosol generating device 100 also includes a first one-way valve 1c disposed in the first channel 1a. The first one-way valve 1c is configured to open when the pressure in the second storage chamber 21 is lower than the pressure in the first storage chamber 11, or to open at least based on its own gravity when the aerosol generating device 100 is in a second posture, to allow fluid to flow unidirectionally from the first storage chamber 11 to the second storage chamber 21 through the first channel 1a. The first one-way valve 1c can prevent fluid from flowing from the second storage chamber 21 to the first storage chamber 11. When the absolute value of the pressure difference between the first storage chamber 11 and the second storage chamber 21 is small, or when the pressures in the first storage chamber 11 and the second storage chamber 21 are equal, the first one-way valve 1c closes, thereby preventing fluid from flowing from the first storage chamber 11 to the second storage chamber 21. In some other usage examples, the first one-way valve 1c in the first channel 1a is deselectable.

[0109] Further, you can refer to Figure 7 A first one-way valve 1c is disposed in the fourth portion 1b2. Furthermore, the first one-way valve 1c is disposed adjacent to the fluid inlet 1b3, thereby preventing at least a portion of the liquid matrix in the first channel 1a from flowing back into the first storage chamber 11, thus allowing a portion of the liquid matrix to remain in the first channel 1a, which helps improve the efficiency of replenishing the liquid matrix to the second storage chamber 21. Preferably, the fluid inlet 1b3 is disposed at the end of the fourth portion 1b2 away from the third portion 1b1. More preferably, the fluid inlet 1b3 is disposed adjacent to the bottom or distal end of the first storage chamber 11. This helps ensure that when the aerosol generating device 100 is in the first position, the fluid inlet 1b3 is submerged in the liquid matrix in the first storage chamber 11, and when the aerosol generating device 100 is in the second position, the fluid inlet 1b3 is positioned above the liquid surface in the first storage chamber 11, preventing the fluid inlet 1b3 from being submerged in the liquid matrix.

[0110] The bottom or far end of the first storage cavity 11 can be the end of the first storage cavity 11 that is away from the driving module 3 or the atomizing module 2.

[0111] In some embodiments, reference may be made to Figure 7The first conduit 1b has a frustoconical through-hole 1b4 and a blocking portion 1b5 with a liquid outlet. The smaller end of the frustoconical through-hole 1b4 faces the fluid inlet 1b3, while the larger end faces away from the fluid inlet 1b3. The first one-way valve 1c includes a ball plug. When the drive module 3 is not working (or when the piston 31 is held in the first position), the ball plug sinks into the frustoconical through-hole 1b4, thereby sealing the frustoconical through-hole 1b4. During the process of injecting gas or liquid matrix into the first storage cavity 11, the gas pressure in the first storage cavity 11 is higher than the gas pressure in the second storage cavity 21. Based on this pressure difference, the spherical plug is pushed up and blocked by the blocking part 1b5, so that the frustum-shaped through hole 1b4 is opened. Alternatively, when the storage module 1 is in a preset posture, the spherical plug is at least dislodged from the frustum-shaped through hole 1b4 under its own gravity, so that the frustum-shaped through hole 1b4 is opened, and then the liquid matrix in the first storage cavity 11 can flow into the second storage cavity 21 through the first channel 1a.

[0112] In some embodiments, reference may be made to Figure 5 The second storage cavity 21 has a proximal end and a distal end arranged opposite to each other, and the nozzle 5 is located near the proximal end of the second storage cavity 21. The second guide hole 252 is located near the proximal end of the second storage cavity 21 to increase the threshold for the liquid to flow out of the second storage cavity 21 through the second guide hole 252 or the second channel 2a. This helps the second storage cavity 21 to store more liquid matrix, thereby allowing the liquid matrix in the second storage cavity 21 to fully wet the atomizing core 22 or to have a larger contact area or conductive area between the second storage cavity 21 and the atomizing core 22. It also helps to prevent the liquid matrix in the second storage cavity 21 from submerging the second guide hole 252 and causing the liquid matrix to flow out when the aerosol generating device 100 is in the first posture.

[0113] In some embodiments, the second guide hole 252 is located closer to the proximal end of the second storage cavity 21 than the atomizing core 22, so that when the aerosol generating device 100 is in the first posture, the atomizing core 22 can maintain a large contact area or conductive area with the liquid matrix in the second storage cavity 21, which helps to keep the atomizing core 22 fully wetted and is beneficial to prevent the atomizing core 22 from dry burning.

[0114] In some embodiments, the first guide hole 251 is disposed near the proximal end of the second storage cavity 21 to increase the threshold for the second storage cavity 21 to flow out through the first guide hole 251 or the first channel 1a. This helps the second storage cavity 21 to store more liquid matrix, thereby enabling the liquid matrix in the second storage cavity 21 to fully wet the atomizing core 22 or to have a larger contact area or conductive area between the second storage cavity 21 and the atomizing core 22. It also helps to prevent the liquid matrix in the second storage cavity 21 from submerging the first guide hole 251 and causing the liquid matrix to flow out when the aerosol generating device 100 is tilted due to use.

[0115] In some embodiments, the first guide hole 251 is located closer to the proximal end of the second storage cavity 21 than the atomizing core 22, so that when the aerosol generating device 100 is used at an angle, the atomizing core 22 can maintain a larger contact area or conductive area with the liquid matrix in the second storage cavity 21, which helps to keep the atomizing core 22 fully wetted and is beneficial to prevent the atomizing core 22 from burning dry.

[0116] In some embodiments, reference may be made to Figure 5 The flow cross-sectional area of ​​the second guide hole 252 is smaller than that of the first guide hole 251. Within a certain range, a larger flow cross-sectional area of ​​the first guide hole 251 helps to improve the efficiency of replenishing the liquid matrix from the first storage cavity 11 to the second storage cavity 21 under the drive of the drive module 3, allowing the liquid level in the second storage cavity 21 to rise more quickly. However, within a certain range, if the area of ​​the second guide hole 252 is too large, it will cause the air pressure in the second storage cavity 21 to drop too quickly or the negative pressure to be too high. This will cause a large amount of external air to enter the second storage cavity 21 through the capillary channel in the atomizing core 222, resulting in a large number of bubbles in the second storage cavity 21 and affecting the replenishment of the liquid matrix from the first storage cavity 11 to the second storage cavity 21. Therefore, making the flow cross-sectional area of ​​the second guide hole 252 smaller than that of the first guide hole 251 is beneficial to ensure that the amount of liquid matrix replenished into the second storage cavity 21 is greater than the amount of gas discharged during at least part of the operation of the drive module 3. This not only helps the first storage cavity 11 to replenish the liquid matrix into the second storage cavity 21 more quickly, but also prevents outside air from entering the second storage cavity 21 through the atomizing core 22.

[0117] In some embodiments, the diameter of the first guide hole 251 is greater than or equal to 1 mm. The diameter of the hole is the shortest distance between its two opposite sides; for example, when the hole is rectangular, the diameter is the length of the shorter side of the rectangle. When the hole is circular, the distance between its two opposite sides is equal to the diameter of the circle, and the diameter of the hole is the diameter of the circle. Preferably, the diameter of the first guide hole 251 is approximately 1 mm.

[0118] In some embodiments, the diameter of the second guide hole 252 is less than 1 mm, for example, the diameter of the second guide hole 252 may be about 0.5 mm.

[0119] In some embodiments, reference may be made to Figure 4 A second one-way valve 2c is provided in the second channel 2a. The second one-way valve 2c is configured to open when the air pressure in the drive module 3 is lower than the air pressure in the second storage chamber 21, allowing fluid to flow unidirectionally from the second storage chamber 21 to the drive module 3 through the second channel 2a. The second one-way valve 2c can prevent fluid from flowing from the drive module 3 to the second storage chamber 21. When the absolute value of the difference between the air pressure in the drive module 3 and the air pressure in the second storage chamber 21 is small, or when the air pressure in the drive module 3 is equal to the air pressure in the second storage chamber 21, the second one-way valve 2c closes, thereby preventing fluid from flowing from the second storage chamber 21 to the drive module 3.

[0120] In some embodiments, reference may be made to Figure 12 and Figure 15 The drive module 3 includes a piston 31 and a pump body 32 having a pump chamber 321 inside. The piston 31 is configured to move relative to the pump body 32 between a first position and a second position, and during the movement between the first position and the second position, the pump chamber 321 draws fluid from the second storage chamber 21, and / or at least a portion of the fluid in the pump chamber 321 is discharged.

[0121] In some embodiments, the drive module 3 further includes a flow channel 33 for discharging at least a portion of the fluid in the pump chamber 321.

[0122] Further, you can refer to Figure 2 , Figure 11 , Figure 13 and Figure 14 When piston 31 moves from the first position to the second position, the second one-way valve 2c closes, and pump chamber 321 connects to guide channel 33. At least a portion of the fluid in pump chamber 321 can be discharged from pump chamber 321, causing a drop in air pressure in pump chamber 321. (See reference...) Figure 12 and Figure 15 When the piston 31 moves from the second position to the first position, the air pressure in the pump chamber 321 is less than the air pressure in the second storage chamber 21, causing the second one-way valve 2c to open, thereby connecting the pump chamber 321 to the second storage chamber 21, and allowing the fluid in the second storage chamber 21 to flow into the pump chamber 321.

[0123] Furthermore, the second check valve 2c is configured to remain closed during the movement of piston 31 from the first position to the second position, and also to remain closed when piston 31 is in the first position.

[0124] In some embodiments, as the piston 31 moves from the second position to the first position, it promotes the flow of fluid in the pump chamber 321 into the guide channel 33, thereby causing the air pressure in the pump chamber 321 to decrease.

[0125] In some embodiments, when the piston 31 is in the first position, reference can be made to Figure 1 and Figure 4 The flow channel 33 is isolated from the pump chamber 321, so that the fluid in the pump chamber 321 cannot flow into the flow channel 33.

[0126] During the movement of piston 31 from the second position to the first position, the second one-way valve 2c opens, making pump chamber 321 connected to the second storage chamber 21, and pump chamber 321 draws in at least part of the fluid in the second storage chamber 21.

[0127] Therefore, when the aerosol generating device 100 is in the first position, the piston 31 can reciprocate between the first and second positions to draw gas from the pump chamber 32, thereby reducing the gas pressure in the second storage chamber 21 and allowing the first storage chamber 11 to replenish the liquid matrix into the second storage chamber 21. When the aerosol generating device 100 is in the second position, the piston 31 can reciprocate between the first and second positions to reduce or empty the liquid matrix in the second storage chamber 21 by drawing it out.

[0128] In some embodiments, the drive module 3 and the first storage cavity 11 have a third channel 3a that connects the two, and the second channel 2a is connected to the third channel 3a through the drive module 3, so that fluid can circulate between the first storage cavity 11 and the second storage cavity 21 through the first channel 1a, the second channel 2a and the third channel 3a.

[0129] For example, the drive module 3 can draw some fluid from the paper in the second storage cavity 21 through the second channel 2a and then introduce it into the first storage cavity 11 through the third channel 3a. The fluid in the first storage cavity 11 can be introduced into the second storage cavity 21 through the first channel 1a.

[0130] The cycle can be driven by the reciprocating motion of piston 31 between a first position and a second position. Fluid flows in the first channel 1a, the second channel 2a, and the third channel 3a, and the actions of piston 31 can occur simultaneously or sequentially.

[0131] In some embodiments, reference may be made to Figure 2During the movement of piston 31 from the first position to the second position, or when piston 31 is in the second position, the guide channel 33 connects pump chamber 321 and third channel 3a. Based on the movement of piston 31, fluid in pump chamber 321 can flow through guide channel 33 to third channel 3a, and then to first storage chamber 11. During the movement of piston 31 from the second position to the first position, second check valve 2c opens, allowing pump chamber 321 to draw fluid from second storage chamber 21 through second channel 2a to replenish insufficient fluid in pump chamber 321 or restore air pressure in pump chamber 321. During the process of fluid in drive assembly 3 being injected into first storage chamber 11 through third channel 3a, at least a portion of the fluid in first storage chamber 11 can be introduced into second storage chamber 21 through first channel 1a.

[0132] Since the fluid can circulate between the first storage chamber 11 and the second storage chamber 21, it is not necessary to precisely control the amount of liquid matrix replenished from the first storage chamber 11 to the second storage chamber 21 each time, thus preventing the liquid matrix in the second storage chamber 21 from leaking out of the aerosol generating device 100 due to oversaturation. Furthermore, even when the drive module 3 is working continuously or for a long time, or when the piston 31 reciprocates repeatedly between the first and second positions, or when the liquid matrix in the second storage chamber 21 is relatively sufficient, the drive module 3 can still replenish the liquid matrix from the first storage chamber 11 to the second storage chamber 21, and prevent the liquid matrix in the second storage chamber 21 from becoming oversaturated and leaking.

[0133] In some embodiments, the drive module 3 includes an electric drive module, and the aerosol generating device 100 further includes a controller (not shown) electrically connected to a battery to control the battery to provide electrical power to the electric drive module, thereby causing fluid in the second storage chamber 21 to be extracted and causing fluid in the first storage chamber 11 to flow into the second storage chamber 21. For example, the electric drive module can drive the piston 31 to move between a first position and a second position based on the electrical power provided by the battery.

[0134] As an example, the aerosol generating device 100 also includes an interactive element that allows input of commands. Users can issue commands to a controller via this element, which in turn controls the electric drive module. The interactive element can include a touchscreen, buttons, knobs, a keyboard, or a remote control (such as a mobile app). The electric drive module can respond to commands by extracting fluid from the second storage chamber 21 for a duration t. For example, after a user issues a command via the interactive element, the electric drive module responds by extracting fluid from the second storage chamber 21 for 5 seconds. After duration t, the electric drive module can automatically stop extracting fluid from the second storage chamber 21. Alternatively, the electric drive module can respond to commands by driving the piston 31 to move back and forth between a first position and a second position N times, where N is an integer and N≥1. After completing N reciprocations, the electric drive module can automatically stop working, and the piston 31 will come to a stop. It should be understood that the electric drive module can also respond to commands in other ways.

[0135] In some embodiments, reference may be made to Figure 4 The drive module 3 also includes an operating element 34 linked to the piston 31. The operating element 34 is configured to be operable to drive the piston 31 from a first position to a second position. This allows the operating element 34 to be manually operated, thereby enabling fluid to flow between the first storage chamber 11 and the second storage chamber 21.

[0136] In some embodiments, reference may be made to Figure 4 The operating component 34 is provided with a first return hole 341 that connects the flow guide channel 33 and the third channel 3a. The first return hole 341 is configured to maintain communication between the third channel and the flow guide channel 33.

[0137] Thus, fluid can flow from the pump chamber 321 into the guide channel 33, then into the operating member 34 through the guide channel 33, then into the third channel 3a through the first return hole 341, and finally into the first storage chamber 11.

[0138] In some embodiments, reference may be made to Figure 1 and Figure 2 The aerosol generating device 100 also includes a support 6, with the atomizing module 2 and the driving module 3 held on the same side of the support 6, and the storage module 1 disposed on the other side of the support 6. The support 6 is provided with a second reflux hole 61 communicating with the first storage cavity 11. Furthermore, the support 6, the driving module 3, or the atomizing module 2 is positioned near the proximal end of the first storage cavity 11.

[0139] The aerosol generating device 100 also includes a third conduit 3b having a third channel 3a inside. One end of the third conduit 3b is connected to the operating member 34, and the other end is connected to the bracket 6. The third channel 3a connects the first reflux hole 341 and the second reflux hole 61, and connects to the first storage cavity 11 through the second reflux hole 61.

[0140] In some embodiments, reference may be made to Figure 2 and Figure 4 The drive module 3 also includes a reset member 35, which acts on the piston 31 or the operating member 34 to automatically reset the piston 31 from the second position to the first position. Of course, the reset member 35 can also provide a damped feel for the user to operate the operating member 34, and can also help keep the piston 31 in the first position.

[0141] Further, you can refer to Figure 2 The reset element 35 is disposed between the operating element 34 and the pump body 32. Furthermore, the reset element 35 includes a spring that can be disposed around the periphery of the piston 31.

[0142] In some embodiments, reference may be made to Figure 4 The drive module 3 also includes a first seal 36 connected to the pump body 32. The piston 31 includes a first tubular body 311, which defines at least a portion of the flow channel 33. A first through hole 312 communicating with the first channel is provided on the side wall of the first tubular body 311. When the piston 31 is in the first position, the first through hole 312 is located in the first seal 36 and is sealed by the first seal 36. When the piston 31 is in the second position, the first through hole 312 is located in the pump chamber 321, thereby getting rid of the seal of the first seal 36 and communicating with the pump chamber 321 and the flow channel 33.

[0143] In some embodiments, reference may be made to Figure 4 The piston 31 includes a second tubular body 313, which connects the operating element and the first tubular body 311. At least a portion of the first tubular body 311 can be retained inside the second tubular body 313. The first tubular body 311 and the second tubular body 313 can be interconnected by assembly, for example, by riveting, to place at least a portion of the first tubular body 311 within the second tubular body 313. The first tubular body 311 and the second tubular body 313 can be integrally formed, for example, by insert injection molding, so that at least a portion of the first tubular body 311 is located within the second tubular body 313. Preferably, the first tubular body 311 and the second tubular body 313 are sealed together to prevent fluid in the flow channel 33 from leaking between the first tubular body 311 and the second tubular body 313.

[0144] In some embodiments, the drive module 3 further includes a cover 37 connected to the pump body 32, and the cover 37 has a through hole through which at least a portion of the piston 31 passes, and the piston 31 can reciprocate along the central axis of the through hole. The cover 37 can support the reset member 35. The cover 37 can be used to push the first seal 36 into the pump body 32 for retention.

[0145] In some embodiments, reference may be made to Figure 3 The support 6 includes an annular retaining wall 62 with a retaining cavity inside, in which at least a portion of the pump body 32 is disposed, such that at least a portion of the pump body 32 is surrounded by the retaining wall 62.

[0146] Furthermore, the cover 37 is disposed on the pump body 32 so that the cover 37 and the pump body 32 form an integral unit that can be assembled together with the retaining wall 62, and after assembly, the cover 37 is connected to the retaining wall 62. Even further, the cover 37 provides a sealing connection between the retaining wall 62 and the pump body 32, so that fluid cannot leak along the surface of the cover 37.

[0147] In some embodiments, reference may be made to Figure 15 When the aerosol generating device 100 is in the second posture, the drive module 3 is configured to extract the liquid matrix in the second storage cavity 21 through the second channel 2a, thereby reducing the liquid matrix in the second storage cavity 21. Figure 15 The thick arrows in the diagram indicate the direction of flow of the liquid matrix.

[0148] In some embodiments, the first pose and the second pose are inverted.

[0149] In some embodiments, when the aerosol generating device 100 is in a first posture, the angle θ between the aerosol generating device 100 and the horizontal direction is a positive angle, and the positive angle between the aerosol generating device 100 and the horizontal direction is greater than or equal to α. When the angle θ between the aerosol generating device 100 and the horizontal direction is a positive angle, 0° < θ ≤ 90°, and the nozzle 5 is vertically upward or tilted upward in the direction away from the ground surface, so that the nozzle 5 is in a state that can be held in the mouth by a user, for example, the nozzle 5 can be held in the mouth by a standing or sitting user. That is, when the aerosol generating device 100 is in the first posture, α < θ ≤ 90°.

[0150] When the aerosol generating device 100 is in the second posture, the angle θ between the aerosol generating device 100 and the horizontal direction includes a negative angle and / or a positive angle less than α. When the angle between the aerosol generating device 100 and the horizontal direction is negative, -90°≤θ≤0°, and the nozzle 5 is vertically downward or tilted downward in the direction towards the ground. In this case, if the user wants to hold the nozzle 5 in their mouth, they need to tilt their head back. That is, when the aerosol generating device 100 is in the second posture, -90°≤θ<α.

[0151] Further, you can refer to Figure 11 When the aerosol generating device 100 is in the first position, the drive module 3 can discharge the gas it extracts from the second storage chamber 21 into the first storage chamber 11 through the third channel 3a; (Refer to...) Figure 14 When the aerosol generating device 100 is in the second position, the drive module 3 can discharge the liquid matrix extracted from the second storage cavity 21 into the first storage cavity 11 through the third channel 3a. Thus, under the power provided by the drive module 3, the liquid matrix in the second storage cavity 21 can be transferred to the first storage cavity 11 for storage. Therefore, when the aerosol generating device 100 is not needed, by placing the aerosol generating device 100 in the second position and then driving the drive module 3 to empty the liquid matrix in the second storage cavity 21, the liquid matrix extracted from the second storage cavity 21 can be transferred to the first storage cavity 11 for storage through the drive module 3. This helps to preserve the liquid matrix in the aerosol generating device 100 and extend its shelf life. It also prevents the liquid matrix in the second storage cavity 21 from leaking through the atomizing core 22. When the aerosol generating device 100 needs to be used again, the aerosol generating device 100 can be put into the first position, and then the driving module 3 can be used to drive the first storage cavity 11 to replenish the liquid matrix to the second storage cavity 21. Figure 11 In the diagram, thick arrows indicate the direction of liquid matrix flow, while thin arrows indicate the direction of gas flow. Figure 14 In the diagram, thick arrows indicate the direction of liquid matrix flow, while thin arrows indicate the direction of gas flow.

[0152] In some embodiments, when the aerosol generating device 100 is in the first posture, the second guide hole 252 is not submerged in the liquid matrix in the second storage cavity 21 because it is located near the proximal end of the second storage cavity 21, thereby enabling the drive module 3 to extract gas from the second storage cavity 21 through the second channel 2a. Specifically, by moving the piston 31, the pump chamber 321 extracts gas from the second storage cavity 21 through the second channel 2a, and then at least a portion of the gas extracted by the pump chamber 321 from the second storage cavity 21 is introduced into the first storage cavity 1a through the third channel 3a.

[0153] When the aerosol generating device 100 is in the second posture, the second guide hole 252 is immersed in the liquid matrix in the second storage cavity 21, thereby enabling the drive module 3 to extract the liquid matrix from the second storage cavity 21 through the second channel 2a. Specifically, by moving the piston 31, the pump chamber 321 extracts the liquid matrix from the second storage cavity 21 through the second channel 2a, and then at least a portion of the liquid matrix extracted by the pump chamber 321 from the second storage cavity 21 is introduced into the first storage cavity 1a through the third channel 3a.

[0154] Alternatively, when the aerosol generating device 100 is in the second posture, the drive module 3 is configured to extract the liquid matrix in the second storage cavity 21 through the second channel 2a, and to introduce at least a portion of the liquid matrix in the drive module 3 into the first storage cavity 11 through the third channel 3a.

[0155] In some embodiments, reference may be made to Figure 5 , Figure 13 and Figure 14 The liquid guide hole 231 on the tube 23 is positioned close to the far end of the second storage chamber 21 to prevent the liquid guide hole 231 from being submerged by the liquid matrix in the second storage chamber 21 when the aerosol generating device 100 is in the second posture. Thus, when the aerosol generating device 100 is in the second posture, some of the gas discharged from the pump chamber 321 into the first storage chamber 11 through the third channel 3a will increase the gas pressure in the first storage chamber 11, causing the first one-way valve 1c to open. Then, the gas in the first storage chamber 11 can be discharged into the second storage chamber 21 through the first channel 1a. Then, some of the gas in the second storage chamber 21 can be discharged into the environment through the liquid guide hole 231 and the atomizing core 22, so that the second storage chamber 21 is basically balanced with the ambient gas pressure.

[0156] Figure 13 The arrows in the diagram indicate the direction of gas flow. Specifically, when there is no liquid matrix or only a small amount of liquid matrix in the pump chamber 321, the arrows indicate the flow trajectory of gas from the pump chamber 321 to outside the atomizing core 22. Figure 14 The thin arrows indicate the direction of gas flow, and the thick arrows indicate the direction of liquid matrix flow. Specifically, the thick arrows indicate the flow trajectory of the liquid matrix from the pump chamber 321 to the first storage chamber 11 when the liquid matrix is ​​in the pump chamber 321, and the thin arrows indicate the flow trajectory of the gas in the first storage chamber 11 to the outside of the atomizing core 22.

[0157] In some embodiments, reference may be made to Figure 1The aerosol generating device 100 also includes an air valve 7, which is configured to have a closed state and an open state. In the open state, the air valve 7 allows the first storage chamber 11 to communicate with the outside environment, thereby helping to balance the air pressure between the first storage chamber 11 and the external environment. When the air valve 7 is in the closed state, the first storage chamber 11 is isolated from the outside environment to prevent fluid in the first storage chamber 11 from flowing to the outside environment other than the first channel 1a or the second storage chamber 21, or to prevent fluid in the first storage chamber 11 from leaking through the air valve 7. When the air valve 7 is in the open state, the first storage chamber 11 can discharge gas to the outside environment and / or draw in outside air through the air valve 7.

[0158] As an example, air valve 7 can automatically switch between an open and closed state in response to changes in the pressure difference between the inside and outside of the first storage chamber 11. For instance, air valve 7 may include a pressure relief valve that opens when the air pressure in the first storage chamber 11 reaches a threshold. When open, the pressure relief valve can discharge gas from the first storage chamber 11 to balance the air pressure in the first storage chamber 11 with the ambient air pressure. When closed, it can prevent leakage of the liquid matrix in the first storage chamber 11. In other words, during the operation of the drive module 3, the pressure relief valve opens or closes by a preset threshold force, thereby maintaining the air pressure in the first storage chamber 11 at a substantially constant state. That is, when the pressure relief valve is open, the first storage chamber 11 is connected to the outside, thereby allowing some gas to be discharged to the outside.

[0159] As an example, the air valve 7 can open under certain conditions, allowing bidirectional flow between the external environment and the fluid in the first storage chamber 11. For instance, the air valve 7 can automatically switch between an open and closed state in response to the deflection of the aerosol generating device 100's operating posture. Furthermore, the air valve 7 is bidirectionally oriented when it is open. Even further, when the air valve 7 is open, if the first storage chamber 11 is replenishing the liquid matrix to the second storage chamber 21, the first storage chamber 11 can draw in air from the outside through the air valve 7, thereby preventing the air pressure in the first storage chamber 11 from dropping too quickly and affecting the replenishment of the liquid matrix from the first storage chamber 11 to the second storage chamber 21. Alternatively, when the drive module 3 discharges gas extracted from the second storage chamber 21 into the first storage chamber 11, the first storage chamber 11 can discharge the gas to the outside through the air valve 7.

[0160] When the air valve 7 is closed, the first storage chamber 11 is not connected to the outside, which can prevent the gas in the first storage chamber 11 from flowing into the outside environment, prevent the liquid matrix in the first storage chamber 11 from leaking through the air valve 7, and also help to keep the liquid matrix in the first storage chamber 11 fresh.

[0161] The air valve 7 can be connected to the storage module 1 and communicates with the first storage cavity 11.

[0162] In some embodiments, reference may be made to Figure 6 The air valve 7 includes a first pressure relief port 71, a second pressure relief port 72, and a valve body 73. The valve body 73 is movable between the first pressure relief port 71 and the second pressure relief port 72. The second pressure relief port 72 is configured to be open when the air valve 7 is open and sealed by the valve body 73 when the air valve 7 is closed. When gas is discharged from the first storage chamber 11 through the air valve 7, at least a portion of the discharged gas can be discharged from the first storage chamber 11 through the second pressure relief port 72. When air is drawn into the first storage chamber 11 through the air valve 7, at least a portion of the drawn-in air can enter the first storage chamber 11 through the second pressure relief port 72. Furthermore, sealing either the first pressure relief port 71 or the second pressure relief port 72 by the valve body 73 will cause the air valve 7 to close.

[0163] In some embodiments, when the air valve 7 is in the open state, the first storage chamber 11 is connected to the second pressure relief hole 72 through the first pressure relief hole 71, so that the gas in the first storage chamber 11 can be discharged to the outside through the first pressure relief hole 71 and the second pressure relief hole 72 in sequence, or the outside air can be drawn into the first storage chamber 11 through the second pressure relief hole 72 and the first pressure relief hole 71 in sequence.

[0164] In some embodiments, reference may be made to Figure 2 Air valve 7 is configured to open when the aerosol generating device 100 is in the first position. (See reference...) Figure 6 The air valve 7 is closed when the aerosol generating device 100 is in the second position. This prevents the liquid matrix in the first storage chamber 11 from leaking through the air valve 7 when the aerosol generating device 100 is in the second position.

[0165] Furthermore, the valve body 73 is configured to interfere with and seal the second pressure relief port 72 when the aerosol generating device 100 is in the second posture. For example, the valve body 73 can seal the second pressure relief port 72 at least under its own weight. Further, see... Figure 2 The valve body 73 is configured to automatically move away from the second pressure relief hole 72 under its own gravity when the aerosol generating device 100 is in the first posture, thereby opening the second pressure relief hole 72. Figure 2 In the image, the arrow indicates the direction of fluid flow.

[0166] Therefore, the valve body 73 can have a relatively large mass. Preferably, the valve body 73 is made of a material with a high density; more specifically, the valve body 73 is made of a material with a density greater than that of the liquid matrix. For example, the valve body 73 can be made of materials such as stainless steel, ceramic, glass, PTFE (Teflon), or POM (polyoxymethylene).

[0167] Alternatively, you can refer to Figure 6 The first pressure relief hole 71 is located near the first storage cavity 11, and the second pressure relief hole 72 is located on the side of the first pressure relief hole 71 away from the first storage cavity 11. When the aerosol generating device 100 is in the second posture, part of the liquid matrix in the first storage cavity 11 can be injected into the air valve 7 through the first pressure relief hole 71 and act on the valve body 73. Thus, the valve body 73 can automatically interfere with and cooperate with the second pressure relief hole 72 under the hydraulic pressure or buoyancy provided by the liquid matrix in the air valve 7, thereby sealing the second pressure relief hole 72. Furthermore, refer to... Figure 2 When the aerosol generating device 100 is in the first position, the liquid matrix in the air valve 7 decreases, or the liquid matrix in the air valve 7 flows back into the first storage chamber 11, or no liquid matrix is ​​injected into the air valve 7. Thus, the valve body 73 can automatically detach from the second pressure relief hole 72 under its own gravity, allowing the second pressure relief hole 72 to open. Alternatively, when the aerosol generating device 100 is in the first position, the liquid level in the first storage chamber 11 or in the air valve 7 can be lowered to prevent the valve body 73 from sealing the second pressure relief hole 72 under the buoyancy provided by the liquid matrix.

[0168] In some embodiments, the first pressure relief hole 71 is disposed near the proximal end of the first storage cavity 11 and is disposed between the first storage cavity 11 and the second pressure relief hole 72, so that when the aerosol generating device 100 is in the first posture, the liquid matrix in the first storage cavity 11 can be prevented from submerging the first pressure relief hole 71 and entering the air valve 7.

[0169] In some embodiments, reference may be made to Figure 6 and Figure 8 The first pressure relief hole 71 is disposed facing the first storage cavity 11, and the second pressure relief hole 72 is disposed away from the first storage cavity 11. The air valve 7 also includes a pressure relief pipe 74. The valve body 73 is disposed in the pressure relief pipe 74 axially movable, and there is a gap between the valve body 73 and the inner wall of the pressure relief pipe 74. The gap is configured to connect the first pressure relief hole 71 and the second pressure relief hole 72 when the air valve 7 is opened.

[0170] Furthermore, a support member 75 is provided inside the pressure relief pipe 74. The support member 75 is configured to block the valve body 73 when the aerosol generating device 100 is in the first posture, so as to prevent the valve body 73 from sealing the first pressure relief hole 71. When the aerosol generating device 100 is in the first posture, the support member 75 can act on the valve body 73, thereby maintaining a gap between the valve body 73 and the first pressure relief hole 71. Thus, the gas in the first storage chamber 11 can enter the pressure relief pipe 74 through the first pressure relief hole 71, and then flow to the second pressure relief hole 72 through the gap between the valve body 73 and the inner wall of the pressure relief pipe 74, and then flow out of the air valve 7 and the first storage chamber 11.

[0171] As an example, you can refer to Figure 8 The support member 75 includes a support rib 751, which may have a second through hole or multiple support ribs 751 spaced apart. The support rib 751 is disposed between the first pressure relief hole 71 and the valve body 73 to support the valve body 73 when the aerosol generating device 100 is in the first posture. The multiple support ribs 751 spaced apart may be located around the first pressure relief hole 71, so that the gas entering through the first pressure relief hole 71 needs to pass between two adjacent support ribs 751 or through the second through hole, and then flow into the gap between the inner wall of the valve body 73 and the pressure relief pipe 74, and then flow to the second pressure relief hole 72. It should be noted that, as used herein, "multiple" refers to two or more.

[0172] Furthermore, the support rib 751 and valve body 73 are configured such that when the support rib 751 supports the valve body 73, the support rib 751 and valve body 73 are in line contact, thereby having a small contact area between the support rib 751 and valve body 73. Therefore, when there is a liquid matrix in the pressure relief pipe 74, the sticking effect between the support rib 751 and valve body 73 can be reduced. Consequently, when the aerosol generating device 100 changes from the first posture to the second posture, it helps the valve body 73 to quickly detach from the support rib 751 and quickly seal the second pressure relief hole 72. This can improve the speed at which the air valve 7 changes from open to closed and the speed at which it responds to the posture change of the air valve 7.

[0173] In this configuration, when the support rib 751 supports the valve body 73, the second pressure relief hole 72 is open, and the air valve 7 is open; when the valve body 73 seals the second pressure relief hole 72, the air valve 7 is closed, and the valve body 73 and the support rib 751 are spaced apart. Providing the support rib 751 inside the pressure relief pipe 74 can shorten the movement stroke of the valve body 73, which helps to increase the speed of the air valve 7 switching between the open and closed states. Preferably, the support rib 751 and the pressure relief pipe 74 are integrally formed.

[0174] The valve body 73 may include a spherical gravity ball to reduce frictional forces during movement of the valve body 73 within the pressure relief pipe 74 and to prevent liquid matrix from adhering to the surface of the valve body 73, thereby facilitating the speed at which the high-pressure air valve 7 transitions between open and closed states. In some embodiments, the valve body 73 is configured to have a smooth surface to reduce liquid matrix adhesion. For example, the surface of the valve body 73 may be smoothed by grinding. In some embodiments, the valve body 73 includes a waterproof / oleophobic film layer disposed on its surface to reduce viscous resistance during movement of the valve body 73 within the pressure relief pipe 74 and to prevent liquid matrix from adhering to the surface of the valve body 73, thereby facilitating the speed at which the high-pressure air valve 7 transitions between open and closed states. In some embodiments, the inner wall of the pressure relief pipe 74 is circular, and preferably the diameter of the gravity ball is 5%-20% smaller than the inner wall diameter of the pressure relief pipe 74.

[0175] As an example, you can refer to Figure 6 The support member 75 includes an elastic member 752 disposed between the first pressure relief hole 71 and the valve body 73. When the aerosol generating device 100 is in a first posture, the elastic member 752 can be elastically compressed; when the aerosol generating device 100 is in a second posture, the elastic member 752 can return to its original shape or be in an elastically compressed state with reduced compression. The elastic member 752 may include a spring.

[0176] In some embodiments, the central axis of the aerosol generating device 100 is parallel to the central axis X of the driving assembly 3, so that the angle between the aerosol generating device 100 and the horizontal direction is equal to the angle between the driving assembly 3 and the horizontal direction, that is, the angle between the driving assembly 3 and the horizontal direction is also θ. Furthermore, the central axes of the first pressure relief hole 71 and the second pressure relief hole 72 are collinear with the central axis X of the driving assembly 3.

[0177] In some embodiments, reference may be made to Figures 16-18 When the angle θ between the aerosol generating device 100 and the horizontal direction is a positive angle, that is, when 0° < θ ≤ 90°, the component of the gravity G of the valve body 73 in the deformation direction of the elastic element 752 is opposite to the direction of the elastic force exerted by the elastic element 752 on the valve body 73. (Refer to...) Figure 19 When the angle θ between the aerosol generating device 100 and the horizontal direction is negative, that is, when -90°≤θ<0°, the component of the gravity G of the valve body 73 in the deformation direction of the elastic element 752 is in the same direction as the elastic force of the elastic element 752 acting on the valve body 73.

[0178] In some embodiments, α satisfies: F = G * sinα; where F is the elastic force exerted by the elastic element 752 on the valve body 73, and G is the weight of the valve body 73. When θ = α, the valve body 73 is basically balanced by forces in the deformation direction of the elastic element 752, thus the valve body 73 can maintain its original relative motion state; for example, the valve body 73 can remain relatively stationary with respect to the second pressure relief hole 72. Therefore, the dividing angle α is mainly related to the elastic force of the elastic element 752 and the weight of the valve body 73. The magnitude of angle α or α′ can be changed by altering the elastic force of the elastic element 752 and the weight of the valve body 73.

[0179] As an example, you can refer to Figure 17 When α < θ ≤ 90°, F < G*sinα, the component of the gravity of the valve body 73 in the deformation direction of the elastic element 752 is greater than the elastic force of the elastic element 752 acting on the valve body 73, and the component of the gravity of the valve body 73 in the deformation direction of the elastic element 752 has the opposite direction to the elastic force of the elastic element 752 acting on the valve body 73. This allows the valve body 73 to overcome the elastic force provided by the elastic element 752 under its own gravity, thereby keeping it away from the second pressure relief hole 72, and thus keeping the second pressure relief hole 72 open and keeping the air valve 7 open.

[0180] As an example, you can refer to Figure 18 When 0° < θ < α, F > G*sinα, the component of the gravity of the valve body 73 in the deformation direction of the elastic element 752 is less than the elastic force of the elastic element 752 acting on the valve body 73, and the component of the gravity of the valve body 73 in the deformation direction of the elastic element 752 has the opposite direction to the elastic force of the elastic element 752 acting on the valve body 73. Thus, the elastic element 752 can elastically push the valve body 73 to the second pressure relief hole 72 and make the valve body 73 seal the second pressure relief hole 72, thereby closing the air valve 7.

[0181] As an example, you can refer to Figure 19 When -90°≤θ<0°, the component of the gravity of the valve body 73 in the deformation direction of the elastic element 752 has the same direction as the elastic force of the elastic element 752. Under the combined action of its own gravity and the elastic force provided by the elastic element 752, the valve body 73 can move to the second pressure relief hole 72 and seal the second pressure relief hole 72, thereby closing the air valve 7.

[0182] As an example, when θ = 0°, the direction of gravity of the valve body 73 is perpendicular to the elastic force of the elastic element 752, so the elastic element 752 can elastically push the valve body 73 to the second pressure relief hole 72 and make the valve body 73 seal the second pressure relief hole 72, thereby closing the air pressure balance module 7.

[0183] This prevents the liquid matrix in the first storage chamber 11 from leaking through the air valve 7 when the user draws the suction nozzle 5, or when the aerosol generating device 100 is placed horizontally (i.e., at θ = 0°), or when the aerosol generating device 100 is in the second posture.

[0184] In some embodiments, when the central axis X of the air valve 7 coincides with the plumb line Y of the valve body 72 and the second pressure relief hole 72 is located above the valve body 73, θ = 90°, so that the valve body 73 can maintain a distance from the second pressure relief hole 72, at least under its own weight, allowing the second pressure relief hole 72 to remain open. At this time, the suction nozzle 5 is vertically upward in the direction away from the ground surface. When the central axis X of the second pressure relief hole 72 coincides with the plumb line Y of the valve body 72 and the second pressure relief hole 72 is located below the valve body 73, θ = -90°, so that the valve body 73 can interfere with the second pressure relief hole 72, at least under its own weight, thereby sealing the second pressure relief hole 72. At this time, the suction nozzle 5 is therefore vertically downward in the direction towards the ground surface.

[0185] In some embodiments, the support member 75 includes both a support rib 751 and an elastic member 752. The support rib 751 is configured to support the valve body 73 when the aerosol generating device 100 is in a first posture, so as to prevent the valve body 73 from excessively compressing the elastic member 752.

[0186] The elastic element 752 can be made of a corrosion-resistant material to prevent the liquid matrix from corroding it. For example, the elastic element 752 can be made of stainless steel. Alternatively, the surface of the elastic element 752 can have an anti-corrosion film, which includes, but is not limited to, a gold film or a nickel film. Based on this, the elastic element 752 can be made of piano wire or the like.

[0187] Of course, in other examples, the support 75 may include an elastic element (not shown) at least partially disposed between the second pressure relief hole 72 and the valve body 73. When the aerosol generating device 100 is in the first posture, the elastic element can be elastically stretched, and when the aerosol generating device 100 is in the second posture, the elastic element can return to its original state or be in an elastically stretched state with reduced stretching.

[0188] In some embodiments, reference may be made to Figure 2 The aerosol generating device 100 also includes a ventilation channel 1d. When the air valve 7 is open, it connects the first storage chamber 11 and the ventilation channel 1d. At least a portion of the ventilation channel 1d is disposed between the drive module 3 and the retaining wall 62. More specifically, at least a portion of the ventilation channel 1d may be disposed between the pump body 32 and the retaining wall 62. Figure 2 In the diagram, the arrow indicates the direction in which the gas in the first storage chamber 11 flows out through the air valve 7 and the ventilation channel 1d.

[0189] Furthermore, the retaining wall 62 is provided with a vent 621 that connects to the outside and the ventilation channel 1d.

[0190] Furthermore, one can refer to Figure 1 The aerosol generating device 100 also includes a housing 8, with an operating element 34 exposed outside the housing 8 so that it can be operated. The operating element 34 is clearance-fitted with the housing 8, so that the gap between the operating element 34 and the housing 8 communicates with the outside world and the vent 621.

[0191] In some embodiments, the diameter of the first pressure relief hole 71 is larger than the diameter of the second pressure relief hole 72, or the cross-sectional area of ​​the first pressure relief hole 71 is larger than the cross-sectional area of ​​the second pressure relief hole 72. Preferably, the diameter of the first pressure relief hole 71 is more than twice the diameter of the second pressure relief hole 72 to ensure that the valve body 73 can adequately seal the second pressure relief hole 72 when the aerosol generating device 100 is in the second posture.

[0192] In some embodiments, reference may be made to Figure 3 and Figure 8 The storage module 1 includes a bottle body 12, a first storage cavity 11 disposed within the bottle body 12, and a bottle opening 13 disposed on the bottle body 12. Liquid matrix can be injected into the first storage cavity 11 through the bottle opening 12. The bottle opening 13 can be disposed near the proximal end of the first storage cavity 11. The air valve 7 also includes a sealing cap 76, at least partially disposed within the bottle opening 13 to close the bottle opening 13. Furthermore, the aerosol generating device 100 also includes a sealing ring 9 disposed between the sealing cap 76 and the storage module 1, the sealing ring 9 providing a seal between the sealing cap 76 and the storage module 1 to prevent leakage of the liquid matrix in the first storage cavity 11 through the bottle opening 13. A valve body 73 can be disposed within the sealing cap 76, or a pressure relief pipe 74 can be connected to the sealing cap 76. A first pressure relief hole 71 can be formed on the pressure relief pipe 74.

[0193] In some embodiments, reference may be made to Figure 2 and Figure 9 The air valve 7 also includes a second seal 77, a second pressure relief hole 72 is disposed on the second seal 77, the second seal 77 is clamped between the bracket 6 and the sealing cover 76, or the second seal 77 is clamped between the pump body 32 and the sealing cover 76, thereby making the second seal 77 and the pressure relief pipe 74 sealed together.

[0194] In some embodiments, reference may be made to Figure 9 The second seal 77 has an annular ridge 772, which can be closed or open. The annular ridge 772 protrudes into the retaining cavity. The annular ridge 772 can be interference-fitted between the retaining wall 62 and the pump body 32 to provide a sealing connection between the retaining wall 62 and the pump body 32.

[0195] Further, you can refer to Figure 2 The second seal 77 can also provide a seal between the pump body 32 and the second conduit 2b to prevent fluid leakage at the connection between the pump body and the second conduit.

[0196] In some embodiments, reference may be made to Figure 10 and Figure 11 The second sealing elements 77 and 77' have bosses 771 protruding towards the interior of the pressure relief pipe 74, and the second pressure relief hole 72 is disposed on the bosses 771 and located inside the pressure relief pipe 74. The bosses 771 can be elastic, for example, they can be made of silicone, so that when the valve body 73 seals the second pressure relief hole 72, the valve body 73 and the bosses 771 fit together elastically, which helps to improve the sealing effect of the valve body 73 on the second pressure relief hole 72. Moreover, the bosses 771 can also deform and / or change their position according to the direction and angle of the pressure exerted by the valve body 73 on them, to adapt to the change of the angle θ between the aerosol generating device 100 and the horizontal direction, so as to effectively seal the second pressure relief hole 72 when the aerosol generating device 100 is in the second posture.

[0197] In some embodiments, reference may be made to Figure 11 The second seal 77′ is connected to the pressure relief pipe 74 and can be held on the pressure relief pipe 74 by riveting, spiral connection, snap-fitting, bonding or welding.

[0198] It should be noted that the ambient air pressure used in this article refers to the air pressure of the environment in which the aerosol generating device 100 is located. When the aerosol generating device 100 is in an open environment, the ambient air pressure is approximately equal to atmospheric pressure. When the aerosol generating device 100 is in a negative pressure environment of a closed space, the ambient air pressure is approximately equal to the air pressure of that closed space.

[0199] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
