The air pressure balance module can be transformed between a first posture and a second posture when in use. When in the first posture, the included angle theta between the air pressure balance module and the horizontal direction satisfies: alpha <= theta <= 90 DEG. When in the second posture, the included angle theta between the air pressure balance module and the horizontal direction satisfies: -90 DEG <= theta < alpha; wherein 0 DEG < alpha <= 90 DEG.

Description

Technical Field

[0001] This application relates to the technical field of valves, and in particular to a pressure balancing module and an aerosol generating device including the pressure balancing module. Background Technology

[0002] The pressure relief module opens when there is high pressure inside the container, allowing pressure to be released. However, to prevent liquid leakage through the pressure relief module when the container is tilted during use, existing pressure relief modules are all one-way valves. These one-way valves only open when the internal pressure exceeds the external pressure by a threshold, and gas can only flow out of the container, not in. Therefore, existing pressure relief modules cannot simultaneously prevent liquid leakage, maintain pressure balance inside and outside the container, or prevent negative pressure from forming within the container. Utility Model Content

[0003] The purpose of this application is to provide a pressure balancing module and an aerosol generating device including the pressure balancing module, wherein the pressure balancing module can be opened when in a first state and closed when in a second state.

[0004] At least one embodiment of this application provides a pressure balancing module, which can switch between a first posture and a second posture during use. When in the first posture, the angle θ between the pressure balancing module and the horizontal direction satisfies: α≤θ≤90°. When in the second posture, the angle θ between the pressure balancing module and the horizontal direction satisfies: -90°≤θ<α; where 0°<α≤90°.

[0005] The pressure balancing module includes a valve body, a pressure relief pipe, a first pressure relief hole, and a second pressure relief hole independent of the first pressure relief hole. The valve body is movably disposed in the pressure relief pipe, and the valve body is configured to open the pressure balancing module when the pressure balancing module is in the first posture, while having a gap between itself and the first pressure relief hole and the second pressure relief hole; and to close the pressure balancing module when the pressure balancing module is in the second posture, by sealing the second pressure relief hole.

[0006] As an example, an elastic element is also included, which is configured to act on the valve body at least when 0°≤θ<α to drive the valve body to seal the second pressure relief port.

[0007] As an example, α satisfies: F = G * sinα; where F is the elastic force exerted by the elastic element on the valve body, and G is the weight of the valve body.

[0008] As an example, the elastic element is disposed in the pressure relief pipe, and the elastic element is located between the first pressure relief hole and the valve body.

[0009] As an example, it also includes a support rib disposed between the first pressure relief hole and the valve body, the support rib being configured to support the valve body when the air pressure balancing module is in the first posture, so as to prevent the valve body from sealing the first pressure relief hole.

[0010] As an example, there is a gap between the valve body and the inner wall of the pressure relief pipe, and there are multiple support ribs spaced apart, so that fluid can flow between the first pressure relief hole and the second pressure relief hole through the gap and through two adjacent support ribs.

[0011] As an example, the support rib is in contact with the valve body line when supporting the valve body.

[0012] As an example, it also includes a boss extending into the interior of the pressure relief pipe, the second pressure relief hole being disposed on the boss and located inside the pressure relief pipe, the boss being elastic to adapt to changes in the angle θ between the pressure balancing module and the horizontal direction to elastically fit the valve body, such that the second pressure relief hole is sealed when the pressure balancing module is in a first posture.

[0013] As an example, the valve body may be made of stainless steel, ceramic, glass, PTFE, or POM.

[0014] As an example, when the central axis of the second pressure relief hole coincides with the counterweight line of the valve body and the second pressure relief hole is located above the valve body, θ = 90°;

[0015] When the central axis of the second pressure relief hole coincides with the weight line of the valve body and the second pressure relief hole is located below the valve body, θ = -90°.

[0016] At least one embodiment of this application provides an aerosol generating device, which includes the aforementioned pressure balancing module, and further includes:

[0017] The storage module has a first storage chamber for storing a liquid matrix, and the first storage chamber is connected to the outside when the pressure balancing module is opened.

[0018] 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

[0019] A drive module is configured to provide power to facilitate the introduction of a liquid matrix from the first storage cavity into the second storage cavity through the first channel.

[0020] The pressure balancing module and aerosol generating device including the pressure balancing module provided in the above embodiments can switch between a first posture and a second posture during use. When in the first posture, the angle θ between the pressure balancing module and the horizontal direction satisfies: α≤θ≤90°. When in the second posture, the angle θ between the pressure balancing module and the horizontal direction satisfies: -90°≤θ<α; where 0°<α≤90°. The pressure balancing module is open when in the first posture, allowing fluid to flow bidirectionally through the pressure balancing module. The pressure balancing module is closed when in the second posture, thereby preventing fluid leakage. Attached Figure Description

[0051] 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. A first channel 1a connects the first storage cavity 11 and the second storage cavity 21. The driving module 3 provides power so that the first storage cavity 11 replenishes the second storage cavity 21 with liquid matrix through the first channel 1a, so that the atomizing core 22 can continue to work and thus enable the aerosol generating device 100 to continue generating aerosol.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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 (not shown), the atomizing module further includes a compartment in which the atomizing core is disposed. The compartment is in communication with the second storage cavity via a liquid channel, allowing a liquid matrix in the second storage cavity 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] In some embodiments, the drive module 3 is configured to draw 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.

[0066] In some embodiments, when the aerosol generating device 100 is in a suction-capable posture, 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. 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 a suction-capable posture, 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 liquid matrix from the first storage chamber 11 through the first channel 1a.

[0067] For example, the drive module 3 includes a suction mechanism, and a second channel 2a is connected between the suction mechanism and the second storage cavity 21. The suction mechanism 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. The manual suction mechanism can be operated by the user to extract gas from the second storage cavity 21.

[0068] If the air pressure in the second storage chamber 21 is too high, it can easily lead to leakage of the liquid matrix in the second storage chamber 21. When replenishing the liquid matrix to the second storage chamber 21 by conventional means, it is usually necessary to monitor the mass of the liquid matrix added to the second storage chamber 21 more accurately 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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 air pressure in the second storage chamber 21 is lower than the air 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, so as 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 difference between the air pressure in the first storage chamber 11 and the air pressure in the second storage chamber 21 is small, or when the air pressure in the first storage chamber 11 is equal to the air pressure in the second storage chamber 21, the first one-way valve 1c closes, thereby preventing fluid from flowing from the first storage chamber 11 to the second storage chamber 21.

[0080] Furthermore, a first one-way valve 1c is disposed in the fourth portion 1b2. Even further, 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 be retained 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 facilitates 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] In some embodiments, reference may be made to Figure 2 and Figure 4 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.

[0092] 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.

[0093] Furthermore, 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 flow 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. When piston 31 moves from the second position to the first position, the air pressure in pump chamber 321 is lower than the air pressure in second storage chamber 21, causing the second one-way valve 2c to open, thus connecting pump chamber 321 to second storage chamber 21, allowing fluid in second storage chamber 21 to flow into pump chamber 321.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] In some embodiments, when the aerosol generating device 100 is in a suction-capable posture, the drive module 3 is configured to extract gas from the second storage chamber 21 through the second channel 2a, thereby reducing the gas pressure in the second storage chamber 21. When the aerosol generating device 100 is in a non-suction-capable posture, the drive module 3 is configured to extract liquid matrix from the second storage chamber 21 through the second channel 2a, thereby reducing the amount of liquid matrix in the second storage chamber 21.

[0119] In some embodiments, the suction orientation and the non-suction orientation are inverted.

[0120] In some embodiments, when the aerosol generating device 100 is in a suction-capable 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′, where 0° < α′ ≤ 90°. 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. In this case, the user needs to tilt their head back if they want to hold the nozzle 5 in their mouth. That is, when the aerosol generating device 100 is in a non-suction-capable posture, -90° ≤ θ < α.

[0121] When the aerosol generating device 100 is in a non-suckable 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 a negative angle, -90°≤θ′≤0°, and the nozzle 5 is vertically downward or tilted downward in the direction towards the ground. At this time, if the user wants to hold the nozzle 5 in their mouth, they need to tilt their head back, or the nozzle 5 is parallel to the horizontal direction.

[0122] Furthermore, when the aerosol generating device 100 is in a suction-capable posture, 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; when the aerosol generating device 100 is in a non-suction-capable posture, the drive module 3 can discharge the liquid matrix it extracts from the second storage chamber 21 into the first storage chamber 11 through the third channel 3a. Thus, under the power provided by the drive module 3, the liquid matrix in the second storage chamber 21 can be transferred to the first storage chamber 11 for storage. Therefore, when the aerosol generating device 100 is not needed, it can be placed in a non-pumpable position, and the liquid matrix in the second storage chamber 21 can be emptied by the drive module 3. The liquid matrix extracted from the second storage chamber 21 can be transferred to the first storage chamber 11 for storage by the drive module 3. This helps to preserve the liquid matrix in the aerosol generating device 100 and extend its shelf life, and also prevents the liquid matrix in the second storage chamber 21 from leaking through the atomizing core 22. When the aerosol generating device 100 needs to be used again, it can be placed in a pumpable position, and the drive module 3 can then drive the first storage chamber 11 to replenish the liquid matrix to the second storage chamber 21.

[0123] More specifically, when the aerosol generating device 100 is in a suction-capable posture, during the movement of the piston 31 from the first position to the second position, the gas pressure in the pump chamber 321 is greater than the gas pressure in the first storage chamber 11, and thus the gas in the pump chamber 321 is discharged into the first storage chamber 11 through the third channel 3a. When the aerosol generating device 100 is in a suction-capable posture, and during the movement of the piston 31 from the second position to the first position, the gas pressure in the pump chamber 321 is less than the gas pressure in the second storage chamber 21, causing the second one-way valve 2c to open. Then, some of the gas in the second storage chamber 21 is drawn into the pump chamber 321 through the second channel 2a, resulting in the gas pressure in the second storage chamber 21 being lower than the gas pressure in the first storage chamber 11. Then, the first one-way valve 1c opens, thereby replenishing the liquid matrix from the first storage chamber 11 to the second storage chamber 21 through the first channel 1a.

[0124] When the aerosol generating device 100 is in a non-pumpable posture, and during the movement of piston 31 from the first position to the second position, the gas pressure in pump chamber 321 is greater than the gas pressure in the first storage chamber 11, and thus the gas in pump chamber 321 is discharged into the first storage chamber 11 through the third channel 3a. When the aerosol generating device 100 is in a non-pumpable posture, and during the movement of piston 31 from the second position to the first position, the gas pressure in pump chamber 321 is less than the gas pressure in the second storage chamber 21, causing the second one-way valve 2c to open, and then the liquid matrix in the second storage chamber 21 is drawn into pump chamber 321 through the second channel 2a. When the aerosol generating device 100 is in a non-pumpable posture, and during the movement of piston 31 from the first position to the second position again, the liquid matrix in pump chamber 321 is discharged into the first storage chamber 11 through the third channel 3a.

[0125] Alternatively, when the aerosol generating device 100 is in a non-pumpable state, 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.

[0126] In some embodiments, reference may be made to Figure 1 and Figure 5 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 a non-pumpable state. Thus, when the aerosol generating device 100 is in a non-pumpable state, 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.

[0127] In some embodiments, reference may be made to Figure 5 The second guide hole 252 is positioned near the proximal end of the second storage cavity 21 so that when the aerosol generating device 100 is in a non-pumpable position, the liquid matrix in the second storage cavity 21 can submerge the second guide hole 252. Thus, when the aerosol generating device 100 is in a non-pumpable position, the pump chamber 321 can draw liquid matrix from the second storage cavity 21 through the second guide hole 252 when the second one-way valve 2c is open, which helps to empty the liquid matrix from the second storage cavity 21.

[0128] In some embodiments, reference may be made to Figure 7The first storage chamber 11 has a proximal end and a distal end arranged opposite to each other. The fluid inlet 1b3 is located near the distal end of the first storage chamber 11 to prevent the fluid inlet 1b3 from being submerged by the liquid matrix in the first storage chamber 11 when the aerosol generating device 100 is in a non-pumpable posture. Furthermore, when the first one-way valve 1c is open, it prevents the liquid matrix in the first storage chamber 11 from being introduced into the second storage chamber 21 through the first channel 1a.

[0129] Furthermore, the bracket 6, the drive module 3, or the atomizing module 2 is positioned near the proximal end of the first storage cavity 11.

[0130] In some embodiments, reference may be made to Figure 1 The aerosol generating device 100 also includes a pressure balancing module 7, which can switch between a first posture and a second posture during use. When in the first posture, it is opened to allow the first storage cavity 11 to communicate with the outside world, and when in the second posture, it is closed to prevent the liquid matrix in the first storage cavity 11 from leaking.

[0131] For example, when the pressure balancing module 7 is opened, if the pressure of the first storage chamber 11 is high, the first storage chamber 11 can release some gas to the outside through the pressure balancing module 7 to reduce the pressure of the first storage chamber 11, thereby preventing the liquid matrix from leaking due to excessive pressure in the first storage chamber 11; if the pressure of the first storage chamber 11 is low, the first storage chamber 11 can draw in some air from the outside through the pressure balancing module 7 to increase the pressure of the first storage chamber 11, thereby balancing the pressure of the first storage chamber 11 with the external ambient pressure.

[0132] Furthermore, when the first storage chamber 11 replenishes the liquid matrix to the second storage chamber 21, the pressure balancing module 7 opens. This allows the first storage chamber 11 to simultaneously draw in air from the outside through the open pressure balancing module 7, preventing the pressure in the first storage chamber 11 from dropping too quickly and affecting the replenishment of the liquid matrix. When the pressure balancing module 7 is closed, the first storage chamber 11 is not connected to the outside, preventing gas from flowing into the external environment and preventing leakage of the liquid matrix through the pressure balancing module 7. It also helps to preserve the liquid matrix in the first storage chamber 11.

[0133] In some embodiments, reference may be made to Figure 6 The air pressure balancing module 7 includes a first pressure relief hole 71, a second pressure relief hole 72, and a valve body 73. The valve body 73 can move between the first pressure relief hole 71 and the second pressure relief hole 72. When the air pressure balancing module 7 undergoes an attitude change, the position of the valve body 73 changes.

[0134] For example, the valve body 73 is configured such that when the pressure balancing module 7 is in the first position, there is a gap between it and the first pressure relief hole 71 and the second pressure relief hole 72, so that the pressure balancing module 7 is open; when the pressure balancing module 7 is in the second position, the second pressure relief hole 72 is sealed, so that the pressure balancing module 7 is closed.

[0135] In other words, the second pressure relief port 72 is open when the pressure balancing module 7 is open and sealed by the valve body 73 when the pressure balancing module 7 is closed. When the first storage chamber 11 releases gas through the pressure balancing module 7, at least a portion of the released gas is discharged from the first storage chamber 11 through the second pressure relief port 72; when the first storage chamber 11 draws in air through the pressure balancing module 7, at least a portion of the drawn-in air enters the first storage chamber 11 through the second pressure relief port 72. It should be noted that sealing either the first pressure relief port 71 or the second pressure relief port 72 with the valve body 73 will cause the pressure balancing module 7 to close.

[0136] In some embodiments, when the pressure balancing module 7 is opened, 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 released to the outside through the first pressure relief hole 71 and the second pressure relief hole 72 in sequence, and 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.

[0137] In some embodiments, when the pressure balancing module 7 changes its attitude, the angle θ between the pressure balancing module 7 and the horizontal direction changes. Thus, by adjusting the angle θ between the pressure balancing module 7 and the horizontal direction, the pressure balancing module 7 can switch between a first attitude and a second attitude, thereby making the pressure balancing module 7 open when in the first attitude and closed when in the second attitude.

[0138] In some embodiments, reference may be made to Figures 11-14 When the pressure balancing module 7 is in the first posture, the angle θ between the pressure balancing module 7 and the horizontal direction satisfies: α≤θ≤90°. When it is in the second posture, the angle θ between the pressure balancing module 7 and the horizontal direction satisfies: -90°≤θ<α.

[0139] Furthermore, the angle θ between the pressure balancing module 7 and the horizontal direction is related to the angle θ′ between the aerosol generating device 100 and the horizontal direction. Thus, when the angle θ′ between the aerosol generating device 100 and the horizontal direction changes, the angle θ between the pressure balancing module 7 and the horizontal direction also changes. Consequently, when the pressure balancing module 7 is in the second posture, the aerosol generating device 100 can prevent the liquid matrix in the first storage cavity 11 from leaking through the pressure balancing module 7.

[0140] As an example, the angle θ between the pressure balancing module 7 and the horizontal direction is equal to the angle θ′ between the aerosol generating device 100 and the horizontal direction. Furthermore, when the aerosol generating device 100 is in a suction-capable posture, the pressure balancing module 7 is in a first posture; when the aerosol generating device 100 is in a non-suction-capable posture, the pressure balancing module 7 is in a second posture. Even further, α′=α.

[0141] In some embodiments, the valve body 73 is configured to interfere with the second pressure relief port 72 to seal the second pressure relief port 72 when the pressure balancing module 7 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 air pressure balance module 7 is in the first posture, thereby opening the second pressure relief hole 72.

[0142] 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 air pressure balancing module 7 is in the second posture, part of the liquid matrix in the first storage cavity 11 can be injected into the air pressure balancing module 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 seal the second pressure relief hole 72 under the hydraulic pressure or buoyancy provided by the liquid matrix in the air pressure balancing module 7. Furthermore, refer to... Figure 2 When the pressure balancing module 7 is in the first position, the amount of liquid matrix injected into the pressure balancing module 7 decreases, or the liquid matrix injected into the pressure balancing module 7 flows back into the first storage chamber 11, or no liquid matrix is ​​injected into the pressure balancing module 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 pressure balancing module 7 is in the first position, the liquid level in the first storage chamber 11 or in the pressure balancing module 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.

[0143] In some embodiments, when the central axis X of the second pressure relief hole 72 coincides with the weight 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. Preferably, θ′ is also equal to 90° at this time, and the suction nozzle 5 is therefore 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 weight 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. Preferably, θ′ is also equal to -90° at this time, and the suction nozzle 5 is therefore vertically downward in the direction towards the ground surface.

[0144] 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, thereby preventing the liquid matrix in the first storage cavity 11 from entering the pressure balance module 7 and immersing the valve body 73 when the pressure balance module 7 is in the first posture.

[0145] As an example, when θ′=90°, the position of the first pressure relief hole 71 is such that the liquid matrix in the first storage cavity 11 cannot submerge the first pressure relief hole 71.

[0146] As an example, when the user holds the nozzle 5 of the aerosol generating device 100, the angle θ′ between the aerosol generating device 100 and the horizontal direction is a positive angle, i.e., 0° < θ′ ≤ 90°. In this case, the nozzle 5 is vertically upward or tilted upward in the direction away from the ground surface. The gravity of the valve body 73 is configured such that when α′ ≤ θ′ ≤ 90° (or α ≤ θ ≤ 90°), the valve body 73 maintains a distance from the second pressure relief hole 72; and when 0° ≤ θ′ ≤ α′ (or 0° ≤ θ ≤ α), the valve body 73 remains sealed to the second pressure relief hole 72 at least under its own gravity. Furthermore, the gravity of the valve body 73 is configured such that when θ′ varies between α′ and 90°, the relative position between the valve body 73 and the second pressure relief hole 72 does not change; and when θ′ < α′ (or θ < α), it automatically moves towards the second pressure relief hole 72 to seal it. Preferably, when θ′<α′, the speed at which the second pressure relief hole 72 seals the second pressure relief hole 72 is greater than the speed at which the liquid matrix in the first storage cavity 11 flows to the second pressure relief hole 72.

[0147] Therefore, when the user holds the nozzle 5 of the aerosol generating device 100 and α′≤θ′≤90°, the pressure balancing module 7 opens, and when 0°≤θ′≤α′, the pressure balancing module 7 closes. This prevents the liquid matrix in the first storage cavity 11 from leaking through the pressure balancing module 7 when the user holds the nozzle 5 of the aerosol generating device 100 and 0°≤θ′≤α′. Here, α or α′ is the boundary angle for the pressure balancing module 7 to switch between the first and second postures.

[0148] 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 at least one material such as stainless steel, ceramic, glass, PTFE (Teflon), or POM (polyoxymethylene).

[0149] In some embodiments, reference may be made to Figure 6 and Figure 8 The pressure balancing module 7 also includes a pressure relief pipe 74, in which a valve body 73 is movably disposed, allowing the valve body 73 to move between a first pressure relief hole 71 and a second pressure relief hole 72 within the pressure relief pipe 74. Furthermore, a gap exists between the valve body 73 and the inner wall of the pressure relief pipe 74, configured to connect the first pressure relief hole 71 and the second pressure relief hole 72 when the pressure balancing module 7 is open. Even further, the valve body 73 moves linearly within the pressure relief pipe 74, and its trajectory may be parallel to or coincide with the axial direction of the pressure relief pipe 74. The first pressure relief hole 71 may face the first storage cavity 11, and the second pressure relief hole 72 may face away from the first storage cavity 11.

[0150] In some embodiments, a support 75 is provided inside the pressure relief pipe 74. The support 75 is configured to block the valve body 73 when the pressure balancing module 7 is in the first posture, to prevent the valve body 73 from sealing the first pressure relief port 71. When the pressure balancing module 7 is in the first posture, the support 75 can act on the valve body 73, thereby maintaining a gap between the valve body 73 and the first pressure relief port 71. This allows gas in the first storage chamber 11 to enter the pressure relief pipe 74 through the first pressure relief port 71, and then flow through the gap between the valve body 73 and the inner wall of the pressure relief pipe 74 to the second pressure relief port 72, and then out of the pressure balancing module 7 and the first storage chamber 11. Conversely, outside air can enter the pressure relief pipe 74 through the second pressure relief port 72, and then flow through the gap between the valve body 73 and the inner wall of the pressure relief pipe 74 to the first pressure relief port 71, and then flow into the first storage chamber 11.

[0151] As an example, you can refer to Figure 6The support member 75 includes an elastic member 752, which is configured to act on the valve body 73 at least when 0° ≤ θ < α, to drive the valve body 753 to seal the second pressure relief port 72. The elastic member 752 helps to promote the movement of the valve body 73 toward the second pressure relief port 72 when θ < α (θ′ < α′), thereby helping to accelerate the speed at which the valve body 73 seals the second pressure relief port 72.

[0152] In some embodiments, reference may be made to Figures 11-13 When the angle θ′ between the aerosol generating device 100 and the horizontal direction is a positive angle, that is, when 0°<θ′≤90°, or 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 14 When the angle θ′ between the aerosol generating device 100 and the horizontal direction is a negative angle, that is, when -90°≤θ′<0°, or 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.

[0153] 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. And / or, 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.

[0154] When θ = α, or 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 or 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.

[0155] For more specific details, please refer to Figure 12 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, thus keeping the second pressure relief hole 72 open and keeping the air pressure balance module 7 open.

[0156] You can refer to Figure 13When 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 pressure balance module 7.

[0157] You can refer to Figure 14 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 dual 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, so that the air pressure balance module 7 is closed.

[0158] When θ = 0°, the direction of gravity of valve body 73 is perpendicular to the elastic force of elastic element 752, so elastic element 752 can elastically push valve body 73 to the second pressure relief hole 72 and make valve body 73 seal the second pressure relief hole 72, thereby closing the air pressure balance module 7.

[0159] Thus, when the user holds the mouthpiece 5 and 0° < θ < α, or when the aerosol generating device 100 is placed horizontally (i.e., at θ = 0°), or when the pressure balancing module 7 is in the second posture, the pressure balancing module 7 can be kept closed, thereby preventing the liquid matrix in the first storage chamber 11 from leaking through the pressure balancing module 7.

[0160] In some embodiments, reference may be made to Figures 11-14 The elastic element 752 is disposed in the pressure relief pipe 74, and the elastic element 752 is located between the first pressure relief hole 71 and the valve body 73.

[0161] Furthermore, when the air pressure balancing module 7 is in the first posture, the elastic element 752 can be elastically compressed; when the air pressure balancing module 7 is in the second posture, the elastic element 752 can return to its original shape or be in an elastically compressed state with reduced compression. The elastic element 752 may include a spring.

[0162] In such Figure 11 In the embodiment shown, a base 741 is provided on the end of the pressure relief pipe 74 facing the first storage cavity 11, a first pressure relief hole 71 is opened on the base 741, and the base 741 supports the elastic member 752.

[0163] 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.

[0164] Of course, in other embodiments, the support member 75 may include an elastic member (not shown) at least partially disposed between the second pressure relief hole 72 and the valve body 73. When the air pressure balancing module 7 is in the first posture, the elastic member can be elastically stretched. When the air pressure balancing module 7 is in the second posture, the elastic member can return to its original state or be in an elastically stretched state with reduced stretching.

[0165] In some embodiments, reference may be made 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 positioned between the first pressure relief hole 71 and the valve body 73 to support the valve body 73 when the pressure balancing module 7 is in its first position, preventing the valve body 73 from sealing the first pressure relief hole 71. The multiple spaced support ribs 751 may be located around the first pressure relief hole 71, so that gas entering through the first pressure relief hole 71 needs to pass between adjacent support ribs 751 or through the second through hole, and then flow into the gap between the valve body 73 and the inner wall of the pressure relief pipe 74, before flowing to the second pressure relief hole 72. It should be noted that, as used herein, "multiple" refers to two or more.

[0166] 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 pressure balancing module 7 changes from open to closed and the speed at which it responds to the posture change of the pressure balancing module 7.

[0167] When the support rib 751 supports the valve body 73, the second pressure relief hole 72 is open, and the air pressure balancing module 7 is open; when the valve body 73 seals the second pressure relief hole 72, the air pressure balancing module 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 improve the speed at which the air pressure balancing module 7 changes between the open and closed states. Preferably, the support rib 751 and the pressure relief pipe 74 are integrally formed.

[0168] 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 contributing to a faster transition speed between the open and closed states of the pressure balancing module 7. 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 can 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 contributing to a faster transition speed between the open and closed states of the pressure balancing module 7. 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.

[0169] 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 pressure balancing module 7 is in the first posture, to prevent the valve body 73 from over-compressing the elastic member 752. When the elastic member 752 is a spring, the support rib 751 can prevent the spring from being over-compressed, which would cause excessive tightness between adjacent turns of the coil in the spring. Therefore, the support rib 751 helps to allow gas to pass between adjacent turns of the coil in the spring, ensuring that the first storage cavity 11 can communicate with the outside through the pressure balancing module 7 when the pressure balancing module 7 is in the first posture.

[0170] In some embodiments, reference may be made to Figure 2 The aerosol generating device 100 also includes a ventilation channel 1d. When the pressure balancing module 7 is opened, it connects the first storage cavity 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 cavity 11 flows out through the pressure balance module 7 and the ventilation channel 1d.

[0171] Furthermore, the retaining wall 62 is provided with a vent 621 that connects to the outside and the ventilation channel 1d.

[0172] 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.

[0173] 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 air pressure balancing module 7 is in the second posture.

[0174] 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 pressure balancing module 7 also includes a sealing cap 76, at least partially disposed within the bottle opening 13 to close it. 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.

[0175] In some embodiments, reference may be made to Figure 2 and Figure 9 The air pressure balance module 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.

[0176] 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.

[0177] Furthermore, 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.

[0178] In some embodiments, reference may be made to Figure 10 and Figure 11The 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 the position of the second pressure relief hole 72 according to the direction and angle of the pressure exerted on them by the valve body 73, thereby adapting to the angle θ′ between the aerosol generating device 100 and the horizontal direction or adapting to the posture changes of the air pressure balancing module 7, so that the second pressure relief hole 72 can be well sealed at any θ when the air pressure balancing module 7 is in the second posture.

[0179] 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.

[0180] 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.

[0181] 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.
