Description

Technical Field

[0001] The present application belongs to the technical field of aerosol generation, and more specifically, relates to a liquid storage component, an atomizer and an aerosol generating device. Background Art

[0002] The aerosol generating device is used to heat and atomize the atomizing medium to form an aerosol after power is turned on, and guide it through the air guide channel for the user to inhale. The aerosol generating device generally includes an atomizer and a power supply component, and the power supply component is used to power the atomizer. The atomizer generally has a liquid storage chamber. Under the premise of ensuring the sealing of the structure, the liquid storage chamber is generally ventilated through a porous heating element and a ventilation channel. After the atomizing matrix is ​​injected into the liquid storage chamber, it is generally locked by the heating element absorbing the atomizing matrix to generate a certain negative pressure in the liquid storage chamber, or the atomizing matrix leaked from the liquid storage chamber to the ventilation channel is stored through the ventilation channel. However, when the air pressure in the liquid storage chamber fluctuates greatly due to the influence of temperature, a large positive pressure difference will be generated between the liquid storage chamber and the ventilation channel and / or the heating element. The positive pressure difference will squeeze out the atomizing matrix stored in the ventilation channel and / or the heating element, and finally cause the atomizing matrix to leak. In addition, when the sealing effect of the liquid storage chamber is poor, leakage often occurs. Utility Model Content

DETAILED DESCRIPTION

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0036] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0037] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0038] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0039] As mentioned in the background technology, under the premise of ensuring the sealing of the structure, the liquid storage chamber is generally ventilated through a porous heating element and a ventilation channel. After the atomized matrix is ​​injected into the liquid storage chamber, the atomized matrix is ​​generally locked by the heating element absorbing the atomized matrix to generate a certain negative pressure in the liquid storage chamber, or the atomized matrix leaked from the liquid storage chamber to the ventilation channel is stored through the ventilation channel. However, when the air pressure in the liquid storage chamber fluctuates greatly due to the influence of temperature, a large positive pressure difference will be generated between the liquid storage chamber and the ventilation channel and / or the heating element. The positive pressure difference will squeeze out the atomized matrix stored in the ventilation channel and / or the heating element, and finally cause the atomized matrix to leak. In addition, when the sealing effect of the liquid storage chamber is poor, leakage often occurs.

[0040] In order to solve the above problems, the embodiment of the present application provides a liquid storage component 300, a nebulizer and an aerosol generating device. By separating the liquid storage component 300 from the nebulizer component 200, the liquid storage component 300 can inject atomizing medium into the nebulizer component 200 through the lower liquid channel 314 so that the nebulizer component 200 can heat and atomize to form an aerosol, and when the liquid storage component 300 is separated from the nebulizer component 200, the piston 320 and the seal 330 can be used to seal the opposite ends of the liquid storage cavity 313 respectively to ensure the sealing of the sealed cavity. That is, when the liquid storage component 300 is in a shelving or transportation state, the liquid storage cavity 313 is not connected to the heating element 210 and the ventilation channel. Even if the liquid storage cavity 313 is in an environment with a large temperature difference, the liquid storage cavity 313 is in a sealed state and there is no leakage.

[0041] Please also read Figures 1 to 5, the liquid storage assembly 300 provided in the embodiment of the present application is now described. The liquid storage assembly 300 is used to provide atomizing medium for the atomizing assembly 200, and includes a liquid storage tank 310, a piston 320 and a sealing member 330; the liquid storage tank 310 has a liquid storage cavity 313 and a lower liquid channel 314 connected to the liquid storage cavity 313; the outer peripheral wall of the piston 320 is in interference fit with the inner peripheral wall of the liquid storage tank 310, and the piston 320 is slidably disposed in the liquid storage cavity 313. The piston 320 can be driven by the driving assembly 400 to slide in the direction of the lower liquid channel 314, so as to inject the atomizing medium in the liquid storage cavity 313 into the atomizing assembly 200 via the lower liquid channel 314.

[0042] The outer wall of the piston 320 is in interference fit with the inner wall of the liquid storage chamber 313 , that is, the piston 320 closes the end of the liquid storage chamber 313 away from the lower liquid channel 314 to ensure that the liquid storage chamber 313 is sealed except for the lower liquid channel 314 .

[0043] When the atomizer assembly 200 and the liquid storage assembly 300 are in an assembled state, the lower liquid channel 314 is connected to the atomizer assembly 200, and the liquid storage assembly 300 supplies liquid to the atomizer assembly 200 through the lower liquid channel 314. When the atomizer assembly 200 and the liquid storage assembly 300 are in a separated state, the lower liquid channel 314 is separated from the atomizer assembly 200. At this time, since the liquid storage chamber 313 is filled with atomizing medium and one end of the liquid storage chamber 313 is sealed by the piston 320, the liquid storage chamber 313 is in a negative pressure state and will not leak. At the same time, the lower liquid channel 314 can also be closed by the sealing member 330, and the opposite ends of the liquid storage chamber 313 are sealed by the piston 320 and the sealing member 330 respectively, so that the liquid storage chamber 313 is in a sealed state.

[0044] In addition, it should be noted that the piston 320 is slidably arranged in the liquid storage chamber 313, and the piston 320 can be driven by the driving assembly 400 to slide in the direction of the lower liquid channel 314, so as to inject the atomized medium in the liquid storage chamber 313 into the atomizing assembly 200 via the lower liquid channel 314. That is, the actual capacity of the atomized medium in the liquid storage chamber 313 is related to the position of the piston 320 in the liquid storage chamber 313. When the piston 320 slides in the liquid storage chamber 313, the actual capacity of the atomized medium can be changed, and the piston 320 can push the atomized medium to be injected into the atomizing assembly 200 from the lower liquid channel 314. With such a setting, quantitative liquid supply can be achieved, that is, the user can control the amount of atomized medium injected from the liquid storage chamber 313 to the atomizing assembly 200 according to the actual amount of suction required, thereby achieving quantitative liquid supply, so that each suction is a brand new medium squeezed out of the liquid storage chamber 313, avoiding medium deterioration and improving the suction taste.

[0045] The liquid storage component 300 in the embodiment of the present application is independently arranged. When the liquid storage component 300 is separated from the atomization component 200, the piston 320 seals one end of the liquid storage chamber 313. When the liquid storage chamber 313 is filled with the atomization medium, it is in a negative pressure state and will not leak. At the same time, the lower liquid channel 314 can be sealed by the sealing member 330, that is, the opposite ends of the liquid storage chamber 313 are respectively sealed by the piston 320 and the sealing member 330, so that the liquid storage chamber 313 is in a sealed state. Even if the liquid storage chamber 313 is in an environment with a large temperature difference, there is no leakage in the liquid storage chamber 313. At the same time, when the liquid storage component 300 is connected to the atomizing component 200, the piston 320 is driven by the driving component 400 to slide in the liquid storage chamber 313 to push the atomized medium in the liquid storage chamber 313 into the atomizing component 200, and there is no need to set a ventilation channel, so that even if the liquid storage chamber 313 is in an environment with a large temperature difference, the liquid storage chamber 313 will not leak through the ventilation channel and the heating element 210. In addition, the piston 320 is slidably arranged in the liquid storage chamber 313, and the atomized matrix in the liquid storage chamber 313 can be injected into the atomizing component 200 through the lower liquid channel 314 by driving the piston 320 by the driving component 400. In this way, quantitative liquid supply can be achieved, that is, the user can control the amount of atomized medium injected from the liquid storage chamber 313 to the atomizing component 200 according to the actual amount of suction required, thereby achieving quantitative liquid supply, so that each suction is a brand new medium squeezed out of the liquid storage chamber 313, avoiding medium deterioration and improving the suction taste.

[0046] In one embodiment, when the liquid storage chamber 313 is filled with the atomizing medium, the side of the piston 320 facing the lower liquid channel 314 abuts against the atomizing medium in the liquid storage chamber 313. When injecting liquid, the lower liquid channel 314 is connected to the atomizing assembly 200, and the atomizing medium is driven to be injected into the atomizing assembly 200 by the piston 320, that is, the side of the piston 320 facing the lower liquid channel 314 is always in contact with the atomizing medium, that is, the variable cavity formed by the piston 320 and the liquid storage chamber 313 is always full of atomizing medium, so there is no problem of a large cavity between the atomizing medium and the piston 320 due to the consumption of the atomizing medium, and then there is no problem of temperature difference leakage and taste attenuation due to the existence of the large cavity.

[0047] In one embodiment, the inner diameter of the lower liquid channel 314 is smaller than the inner diameter of the liquid storage chamber 313. By setting the lower liquid channel 314 radially contracted relative to the liquid storage chamber 313, the speed of the atomized medium in the liquid storage chamber 313 entering the atomization assembly 200 can be slowed down to achieve quantitative delivery.

[0048] In one embodiment, the length and inner diameter of the lower liquid channel 314 are set so that when the liquid storage chamber 313 is filled with the atomizing medium and the lower liquid channel 314 is connected to the atomizing assembly 200, the atomizing medium in the liquid storage chamber 313 will not flow into the atomizing assembly 200 under the action of its own gravity. Alternatively, the atomizing medium in the liquid storage chamber 313 flows into the lower liquid channel 314 under the action of gravity, and at this time, there is a negative pressure in the liquid storage chamber 313, and the atomizing medium is locked in the liquid storage chamber 313 by the adsorption effect of the negative pressure and the lower liquid channel 314, and will not be injected into the atomizing assembly 200. Such a setting makes it possible for the liquid storage chamber 313 to be in a standby state without leakage, and in actual application, the user can drive the piston 320 according to the amount of suction required each time, so as to quantitatively deliver the atomizing medium to the atomizing assembly 200.

[0049] Among them, the setting of the length and inner diameter of the lower liquid channel 314 is related to the viscosity of the atomizing medium. For example, when the viscosity of the atomizing medium is higher, the fluidity of the atomizing medium is worse. At this time, the length of the lower liquid channel 314 can be set shorter and / or the inner diameter of the lower liquid channel 314 can be set larger; when the viscosity of the atomizing medium is lower, the fluidity of the atomizing medium is better. At this time, the length of the lower liquid channel 314 can be set longer and / or the inner diameter of the lower liquid channel 314 can be set smaller so as to lock the atomizing medium in the lower liquid channel 314. No sole limitation is made here.

[0050] In one embodiment, see Figures 3 to 5 The liquid storage tank 310 includes a liquid storage cylinder 311 and a needle 312, a liquid storage cavity 313 is formed in the liquid storage cylinder 311, a connector 3113 is formed at one end of the liquid storage cylinder 311 away from the piston 320, the needle 312 is interference-fitted outside the connector 3113 and is detachable, and a lower liquid channel 314 is formed at one end of the needle 312 away from the connector 3113. Among them, by detachably connecting the liquid storage cylinder 311 and the needle 312, and forming the lower liquid channel 314 in the needle 312, the needle 312 with a lower liquid channel 314 of different sizes can be selected according to the atomized medium of different viscosities, so that the liquid storage assembly 300 can be applied to atomized media of different viscosities, and the atomized medium can be a liquid medium or a paste medium. It can be understood that in other real-times of the present application, the needle 312 can also be connected to the liquid storage cylinder 311 as a whole, which is not the only limitation here.

[0051] In one embodiment, see Figure 4The liquid storage cylinder 311 includes a barrel 3111, a connecting portion 3112 and a connecting head 3113. The barrel 3111 is cylindrical, the connecting portion 3112 is connected between the bottom of the barrel 3111 and the connecting head 3113, the connecting portion 3112 is conical, the inner diameter of the connecting portion 3112 gradually decreases from the barrel 3111 to the connecting head 3113, and the connecting head 3113 extends from the bottom center of the connecting portion 3112 along the axial direction of the barrel 3111 in a direction away from the barrel 3111. Among them, by setting the connecting portion 3112 to be conical, the atomized medium in the barrel 3111 can be quickly introduced into the connecting head 3113. In addition, the barrel 3111, the connecting portion 3112 and the connecting head 3113 are connected as one body.

[0052] In one embodiment, see Figure 4 The needle 312 includes a sleeve portion 3121 and an injection portion 3122, the sleeve portion 3121 and the injection portion 3122 are integrally connected along the axial direction of the lower liquid channel 314, the sleeve portion 3121 is sleeved on the outside of the connecting head 3113, and a first step surface is connected between the inner circumferential surface of the sleeve portion 3121 and the inner circumferential surface of the injection portion 3122, the first step surface abuts against the end surface of the connecting head 3113 facing away from the cylinder 3111, the lower liquid channel 314 is formed in the injection portion 3122, and a connecting channel 3114 is formed in the center of the connecting head 3113, and the connecting channel 3114 is connected between the liquid storage chamber 313 and the lower liquid channel 314.

[0053] In one embodiment, see Figure 4 The port of the connecting channel 3114 away from the liquid storage chamber 313 is the liquid injection port 3115. The user can inject the atomized medium into the liquid storage chamber 313 through the liquid injection port 3115. After the liquid storage chamber 313 is filled, the needle 312 is put on, and finally the seal 330 is put on. The operation is simple. In practical applications, an oil filling and capping device can be prepared. After each oil filling, the needle 312 and the seal 330 are conveyed through the vibration plate to realize the full automation of oil filling and capping. In addition, the device is simple and easy to operate, the cost is controllable, and the full process service can be provided to improve the added value.

[0054] In one embodiment, see Figure 4 The outer circumference of the connector 3113 is a conical surface, the inner circumference of the sleeve 3121 is a conical surface, and the inner diameter of the sleeve 3121 gradually increases from the injection portion 3122 to the direction away from the injection portion 3122. During assembly, the sleeve 3121 is pushed along the axial direction of the connector 3113 to be sleeved on the outside of the connector 3113, and the inner circumference of the sleeve 3121 is in interference contact with the outer circumference of the connector 3113.

[0055] In one embodiment, see Figure 3 and Figure 4The inner circumferential surface of the liquid storage chamber 313 is a cylindrical surface, and the outer circumferential surface of the piston 320 is also a cylindrical surface. The outer circumferential surface of the piston 320 is coaxially arranged with the inner circumferential surface of the liquid storage chamber 313. When the driving assembly 400 drives the piston 320, the piston 320 slides along the axial direction of the liquid storage chamber 313, thereby pushing the atomized medium along the axial direction of the liquid storage chamber 313.

[0056] In one embodiment, see Figure 3 and Figure 4 , the lower liquid channel 314 is in the shape of a long cylinder, the liquid storage chamber 313 is also in the shape of a cylinder, the central axis of the lower liquid channel 314 is coaxially arranged with the central axis of the liquid storage chamber 313, and the lower liquid channel 314 is located at the center of one end of the liquid storage chamber 313 away from the piston 320. In this way, when the piston 320 squeezes and pushes the atomized medium, the atomized medium at various locations in the liquid storage chamber 313 can flow evenly into the lower liquid channel 314 in the lateral direction, and the height of the atomized medium is uniformly decreased to ensure that the piston 320 always maintains uniform contact with the atomized medium, which can not only realize quantitative liquid injection, but also reduce the leakage caused by the cavity between the piston 320 and the atomized medium. Among them, the lateral direction is the direction perpendicular to the axial direction of the liquid storage chamber 313.

[0057] In one embodiment, at least the portion where the needle 312 and the liquid storage cylinder 311 are connected to each other is made of a sealing material, so that the needle 312 and the liquid storage cylinder 311 can be connected to each other with good sealing at the connection. The sealing material can be silicone, rubber or metal.

[0058] In a specific embodiment, the needle 312 is made of a sealing material as a whole. In other embodiments, the sleeve portion 3121 is made of a sealing material, and the injection portion 3122 is made of a non-sealing material, and the sleeve portion 3121 and the injection portion 3122 are integrally connected by secondary injection molding, or integrally connected by pressing, or connected by gluing.

[0059] In one embodiment, the piston 320 is made of a sealing material to ensure that the piston 320 is sealed and connected to the liquid storage tank 310. Specifically, the piston 320 can be made of soft rubber or metal material.

[0060] In one embodiment, see Figure 3 and Figure 4, the liquid storage component 300 also includes a liquid storage bracket 340, the liquid storage tank 310 is detachably mounted on the liquid storage bracket 340, the liquid storage bracket 340 can be used to realize the detachable connection between the liquid storage component 300 and the power supply component 100, and the liquid storage bracket is also used to realize the detachable connection between the liquid storage component 300 and the atomization component 200. During assembly, the liquid storage tank 310 can be loaded onto the liquid storage bracket 340, and then the liquid storage bracket 340 is detachably connected with the power supply component 100 and the atomization component 200. In addition, after the atomization medium in the liquid storage tank 310 is used up, the liquid storage tank 310 can be disassembled and replaced with a new liquid storage tank 310. In addition, when the user does not need to use it for a long time, the liquid storage tank 310 or the liquid storage component 300 can also be disassembled as a whole and stored in a refrigerator for refrigeration to keep the atomization medium fresh.

[0061] In one embodiment, see Figure 4 A storage chamber 341 is formed in the liquid storage bracket 340, and the storage chamber 341 passes through the opposite sides of the liquid storage bracket 340 along the axial direction of the liquid storage chamber 313. The storage chamber 341 includes a first storage portion 3411, a second storage portion 3412 and a third storage portion 3413 that are connected in sequence along the axial direction of the liquid storage chamber 313. A first limiting portion 3414 is connected between the first storage portion 3411 and the second storage portion 3412. The first limiting portion 3414 is a conical surface. A second step surface 3415 is connected between the inner wall surface of the second storage portion 3412 and the inner wall surface of the third storage portion 3413. The port of the first storage portion 3411 away from the second storage portion 3412 is an assembly port, and the port of the third storage portion 3413 away from the second storage portion 3412 is a guide port. The liquid storage tank 310 is installed into the storage cavity 341 from the assembly port, and the cylinder 3111, the connecting part 3112 and the connecting head 3113 are sequentially received in the first receiving part 3411, the first limiting part 3414 and the second receiving part 3412, and the outer peripheral surface of the connecting part 3112 abuts against the inner wall surface of the first limiting part 3414, thereby forming an axial limit for the liquid storage tank 310. The sleeve part 3121 and the injection part 3122 of the needle 312 are respectively received in the second receiving part 3412 and the third receiving part 3413, and the third step surface connected between the outer peripheral surface of the sleeve part 3121 and the outer peripheral surface of the injection part 3122 abuts on the second step surface 3415, and the injection part 3122 extends from the guide outlet to connect with the atomizer assembly 200.

[0062] In one embodiment, see Figure 4 The outer wall of the sleeve portion 3121 is in interference fit with the inner wall of the second receiving portion 3412, so that external gas can be prevented from flowing through the gap between the sleeve portion 3121 and the liquid storage bracket 340 and entering the side of the piston 320 away from the lower liquid channel 314, thereby preventing the piston 320 from sliding under the action of external gas.

[0063] In one embodiment, see Figure 3 , Figure 4 and Figure 6 , the liquid storage bracket 340 is formed with a first air guide channel 342, an air inlet hole 344 and a connecting groove 343, the connecting groove 343 is used to communicate with the atomizing chamber of the atomizing assembly 200, and the connecting groove 343 is connected between the first air guide channel 342 and the air inlet hole 344. External gas enters the connecting groove 343 through the air inlet hole 344, and enters the atomizing chamber from the connecting groove 343, so that the aerosol generated in the atomizing chamber can be carried away, and is exported from the first air guide channel 342 for the user to inhale. It can be understood that in other embodiments of the present application, the connecting groove 343 may not be provided on the liquid storage bracket 340, the air inlet hole 344 may be formed in the atomizing assembly 200, and the first air guide channel 342 is directly connected to the atomizing chamber, which is not the only limitation here.

[0064] In one embodiment, see Figure 4 The outlet is connected to the connection groove 343, and the liquid injection portion 3122 extends from the outlet and passes through the connection groove 343 to communicate with the heating element 210 in the atomization assembly 200. It can be understood that in other embodiments, the outlet may not be connected to the connection groove 343, but may be spaced apart from the connection groove 343, which is not limited here.

[0065] In one embodiment, see Figure 4 and Figure 5 The connecting groove 343 penetrates the side of the liquid storage bracket 340 facing the atomization assembly 200, and the atomization chamber penetrates the side of the atomization assembly 200 facing the liquid storage bracket 340. When the liquid storage bracket 340 and the atomization assembly 200 are abutted and assembled, the connecting groove 343 is connected to the atomization chamber.

[0066] In one embodiment, see Figure 4 and Figure 6 , the air inlet 344 and the first air guide channel 342 are arranged at opposite ends of the connecting groove 343 in the horizontal direction, wherein the horizontal direction is a direction perpendicular to the axial direction of the liquid storage chamber 313. The air inlet 344 extends horizontally from the outer side of the liquid storage bracket 340 to the connecting groove 343, and the connecting groove 343 extends horizontally on the side of the liquid storage bracket 340 facing the atomization bracket 230. The first air guide channel 342 extends from the connecting groove 343 along the axial direction of the liquid storage chamber 313, and the central axis of the first air guide channel 342 is arranged parallel to the central axis of the liquid storage chamber 313. The external atmosphere enters the connecting groove 343 through the air inlet 344, and carries the aerosol formed by heating and atomization in the atomization chamber, and is finally discharged through the first air guide channel 342.

[0067] In one embodiment, see Figure 7A window 345 is formed at the position of the liquid storage bracket 340 corresponding to the liquid storage cavity 313, and the user can observe the remaining amount of the atomized medium in the liquid storage cavity 313 through the window 345, so that the liquid storage component 300 can be replaced in time.

[0068] On the second aspect, the present application also provides an atomizer, including an atomization assembly 200, a drive assembly 400 and a liquid storage assembly 300, wherein the drive assembly 400 is used to drive the piston 320 to slide in the liquid storage chamber 313 to inject the atomization medium in the liquid storage chamber 313 into the atomization assembly 200 via the lower liquid channel 314.

[0069] Among them, the atomization component 200 is used to be electrically connected to the power supply component 100, the driving component 400 is used to drive the piston 320 to slide in the liquid storage chamber 313 to inject the atomization medium in the liquid storage chamber 313 into the atomization component 200, and the atomization component 200 is used to heat the atomization medium and atomize it to form an aerosol after power is turned on.

[0070] In this embodiment, by independently arranging the liquid storage component 300, the atomization component 200 and the drive component 400, not only is the sealing of the liquid storage component 300 good when it is in a state of storage or transportation, but there is no leakage. At the same time, by driving the piston 320 to move by the drive component 400, not only is the liquid storage component 300 convenient to supply liquid, but also quantitative liquid supply can be achieved. In addition, by separately arranging the liquid storage component 300, the atomization component 200 and the drive component 400, the liquid storage component 300 and the atomization component 200 can be sold separately, disassembled separately for cleaning or replacement, and the blockage of the atomization component 200 is reduced, thereby improving the suction taste.

[0071] In one embodiment, see Figure 3 , Figure 8 and Fig. 9 , the atomization assembly 200 includes a heating element 210, a liquid inlet channel 2114 is formed at the center of the heating element 210, and a lower liquid channel 314 extends into the liquid inlet channel 2114 to communicate with the liquid inlet channel 2114. The atomized medium in the liquid storage chamber 313 is injected into the liquid inlet channel 2114 via the lower liquid channel 314, so as to be heated and atomized by the heating element 210 to form an aerosol. Among them, the arrangement of the lower liquid channel 314 and the liquid inlet channel 2114 enables the atomized medium in the liquid storage chamber 313 to be away from the heating element 210, so that the heat of the heating element 210 will not be transferred to the atomized medium in the liquid storage chamber 313, which can reduce the risk of oxidation and contamination of the atomized medium in the liquid storage chamber 313, and further enable the atomized medium in the liquid storage chamber 313 to be kept fresh, ensuring that the atomized medium injected into the heating element 210 each time can be fresh, thereby ensuring the taste of the suction.

[0072] In one embodiment, see Figures 8 to 10The heating element 210 includes a porous liquid guide 211 and a heating film 212. A liquid inlet channel 2114 is formed in the liquid guide 211. The heating film 212 is attached to the outer surface of the heating element 210. The heating film 212 is electrically connected to the power supply assembly 100 through the electrode column 240. When the atomized medium is injected into the liquid inlet channel 2114 through the lower liquid channel 314, the atomized medium will enter the various gaps of the liquid guide 211. When the power supply assembly 100 supplies power to the heating film 212 through the electrode column 240, the heating film 212 is powered on to generate heat and heats the atomized medium in the liquid guide 211 to form an aerosol.

[0073] In one embodiment, see Figure 3 The liquid inlet channel 2114 is coaxially arranged with the lower liquid channel 314, and the bottom end of the lower liquid channel 314 is connected with the top end of the liquid inlet channel 2114. The above arrangement not only allows the atomized medium in the lower liquid channel 314 to be quickly injected into the liquid inlet channel 2114, but also allows the heating element 210 to be as far away from the atomized medium in the liquid storage chamber 313 as possible, so that the atomized medium in the liquid storage chamber 313 can be kept fresh.

[0074] In one embodiment, see Figures 8 to 10 The liquid guide member 211 includes a liquid guide portion 2111 having a liquid inlet channel 2114 and a flange 2112 formed at the periphery of one end of the liquid guide portion 2111 away from the lower liquid channel 314. The heating film 212 is attached to the flange 2112, so that the heating film 212 can be away from the atomized medium in the liquid storage chamber 313, thereby keeping the atomized medium fresh.

[0075] Specifically, the liquid guide portion 2111 is cylindrical, the liquid inlet channel 2114 is formed at the center of the liquid guide portion 2111, and the liquid injection portion 3122 of the needle 312 is inserted into the liquid guide portion 2111 to form a connection between the lower liquid channel 314 and the liquid inlet channel 2114. The heating film 212 is attached to the outer surface of the flange 2112.

[0076] In this embodiment, since the heating element 210 is not directly connected to the liquid storage chamber 313, the liquid storage chamber 313 does not need to completely rely on the heating element 210 to achieve power consumption balance and ventilation and liquid removal (of course, the heating element 210 can be used to achieve power consumption balance and ventilation and liquid removal). In this way, the requirements for the structure and materials of the heating element 210 can be reduced. The design of the heating element 210 only needs to meet the advantages of liquid conduction, heat conduction and high service life. At this time, not only ceramics can be used to make the liquid guiding part 211, but also materials other than ceramics can be used to make the liquid guiding part 211. For example, oil-conducting cotton can be used as the liquid guiding part 211 to reduce the cost of the liquid guiding part 211 and shorten the development cycle of the liquid guiding part 211.

[0077] In one embodiment, see Figures 8 to 10The atomization assembly 200 also includes an atomization seat 220, in which the heating element 210 is accommodated. The atomization seat 220 and the heating element 210 together form an atomization cavity. The aerosol formed by heating and atomization of the heating element 210 is guided into the atomization cavity, and then guided out through the first air guide channel 342.

[0078] To solve the above problems, see Figure 8 and Fig.11 At least one inner wall of the atomizing seat 220 is formed with an adsorption channel 222 extending along the axial direction of the liquid storage cavity 313. The adsorption channel 222 can adsorb and store the excess atomizing medium in the heating element 210. When the heating element 210 is powered on and heated, the heating element 210 can absorb the atomizing medium in the adsorption channel 222 and heat it to atomize.

[0079] In one embodiment, see Figure 8 and Fig.11 The inner walls of the atomizer seat 220 on both sides opposite to each other in the first direction are respectively formed with adsorption channels 222, the air inlet hole 344 and the first air guide channel 342 are spaced apart along the second direction, the first direction and the second direction are perpendicular to each other, and both the first direction and the second direction are transverse directions perpendicular to the axial direction of the liquid storage chamber 313.

[0080] Preferably, the adsorption channel 222 is a capillary channel.

[0081] In one embodiment, see Figure 8 The liquid guiding member 211 has two side plates 2113 extending from opposite sides along the first direction. The side plates 2113 are attached to the inner wall of the atomizing seat 220 having the adsorption channel 222. The atomizing medium in the side plates 2113 can be adsorbed and stored by the adsorption channel 222. The atomizing medium in the adsorption channel 222 can enter the liquid guiding member 211 through the gap of the side plates 2113 to be heated and atomized by the heating film 212.

[0082] In one embodiment, see Figure 8 and Fig.10 The heating film 212 is covered on the flange 2112 except the two side plates 2113, that is, the heating film 212 extends from the side of the flange 2112 away from the liquid storage chamber 313 from the two opposite sides of the flange 2112 along the second direction to the side surface of the flange 2112 facing the liquid storage chamber 313. The second direction is perpendicular to the first direction, and the second direction is perpendicular to the axial direction of the liquid storage chamber 313.

[0083] In one embodiment, the two side plates 2113 are respectively formed on two opposite sides of the flange 2112 along the first direction, and the two side plates 2113, the flange 2112 and the liquid guiding portion 2111 are an integrally connected structure.

[0084] In one embodiment, see Fig.11 The atomizer seat 220 has baffles 223 extending inward from the tops of the two opposite sides along the second direction. The setting of the baffles 223 can shield the condensate in the connecting groove 343 to a certain extent to prevent the condensate from directly flowing into the heating film 212 and affecting the operation of the heating film 212.

[0085] Also, see Figure 3 The top side surface of the atomizer seat 220 along the axial direction of the liquid storage chamber 313 is higher than the top side surface of the atomizer bracket 230 facing the liquid storage chamber 313, so that the condensed liquid can be blocked to a certain extent.

[0086] In one embodiment, see Figure 8 , Fig. 9 and Fig.12 The atomizer assembly 200 further includes an atomizer bracket 230, and a first mounting groove 231 is formed inwardly on one side of the atomizer bracket 230 facing the liquid storage bracket 340, and the atomizer seat 220 is received in the first mounting groove 231. The atomizer seat 220 forms a second mounting groove 221 with an opening toward the liquid storage bracket 340, and the heating element 210 is installed in the second mounting groove 221. The heating element 210 and the atomizer seat 220 jointly form an atomizer cavity 250 with an opening toward the atomizer bracket 230. When the atomizer bracket 230 abuts against the liquid storage bracket 340, the connecting groove 343 is just connected with the atomizer cavity 250.

[0087] In one embodiment, see Fig. 9 , Fig.11 and Fig.12 Two first through holes 224 are formed on the side of the atomizer seat 220 away from the liquid storage chamber 313, and two second through holes 232 are formed on the atomizer bracket 230 corresponding to the two first through holes 224. The electrode column 240 connected between the power supply component 100 and the heating film 212 passes through the first through hole 224 and the second through hole 232 to elastically abut against the heating film 212, thereby supplying power to the heating film 212.

[0088] In one embodiment, see Figure 3 The driving assembly 400 includes a driving bracket 410, a driving member 420 and a push rod 430. The driving member 420 is rotatably mounted on the driving bracket 410. The driving bracket 410 has an axial limiting effect on the driving member 420. The driving member 420 is threadedly connected to the push rod 430, and the push rod 430 abuts against the piston 320. When driving, it is only necessary to rotate the driving member 420 on the driving bracket 410. Since the driving member 420 is threadedly connected to the push rod 430, and the driving member 420 is axially limited by the driving bracket 410, when the driving member 420 rotates, it can drive the push rod 430 to move axially, so as to push the piston 320 to move in the liquid storage chamber 313, so as to squeeze the atomized medium into the atomizing assembly 200.

[0089] In this embodiment, the pitch of the driving member 420 and the push rod 430 can be set so that the push rod 430 can drop a preset height every time the driving member 420 rotates one circle, and the inner diameter of the liquid storage chamber 313 is set so that the piston 320 drops a preset height every time the liquid storage chamber 313 injects a preset amount of atomizing medium into the atomizing assembly 200, thereby realizing quantitative liquid supply. For example, the extrusion amount per rotation of 1 circle is 0.05 mg, which can be used for the user to draw 10 mouthfuls, and each time the user can rotate the driving member 420 according to his own dosage to realize dosage control. In the embodiment of the present application, quantitative liquid supply is realized by threading the driving member 420 and the push rod 430, and the structure is simple, reliable, and low in cost. It can be understood that in other embodiments of the present application, it can also be directly positioned and supplied by an electric push rod 430, a cylinder or a linear motor, which is not the only limitation here.

[0090] In one embodiment, see Figure 3 The driving member 420 includes a disk 421 and a first connecting rod 422 formed at the center of one side of the disk 421. A threaded hole 423 is formed at the center of the driving member 420. The threaded hole 423 extends from one end of the first connecting rod 422 away from the disk 421 to the disk 421 and ends at a position close to the side of the disk 421 away from the first connecting rod 422. The push rod 430 includes an abutment portion 431 and a second connecting rod 432 formed on the abutment portion 431. An external thread is formed on the outer peripheral wall of the second connecting rod 432. The second connecting rod 432 is threadedly inserted into the threaded hole 423 of the first connecting rod 422, and the outer peripheral wall of the second connecting rod 432 is threadedly connected to the inner peripheral wall of the first connecting rod 422. A support surface 4111 is formed on the driving bracket 410, and a through groove 4112 is extended from the supporting surface 4111 to the direction of the liquid storage bracket 340. The disk 421 of the driving member 420 is supported on the supporting surface 4111. The first connecting rod 422 of the driving member 420 is arranged through the through groove 4112. The second connecting rod 432 of the push rod 430 passes through the through groove 4112. The abutment portion 431 of the push rod 430 extends from the through groove 4112 to abut on the piston 320. When the disk 421 is rotated on the supporting surface 4111, the push rod 430 drives the abutment portion 431 to move away from the disk 421 to push the piston 320 to move in the liquid storage chamber 313.

[0091] In one embodiment, see Figure 3The central axis of the disk 421, the central axis of the first connecting rod 422, the central axis of the second connecting rod 432, the central axis of the piston 320 and the central axis of the liquid storage chamber 313 are coaxially arranged. In this arrangement, when the disk 421 is rotated, the second connecting rod 432, the abutting portion 431 and the piston 320 all move along the axial direction of the liquid storage chamber 313, so that the atomized medium in the liquid storage chamber 313 is injected into the atomizing assembly 200 downward along the axial direction of the liquid storage chamber 313.

[0092] In one embodiment, see Figure 3 Assuming that the axial length of the first connecting rod 422 is L1, the axial length of the through groove 4112 is L2, and the axial length of the abutment portion 431 is L3, then L2-L1 is greater than L3, and the length of the threaded hole 423 is greater than the length of the second connecting rod 432. In this way, when the second connecting rod 432 is fully inserted into the threaded hole 423, the abutment portion 431 can be accommodated in the through groove 4112, so that the surface of the driving assembly 400 is neat during transportation, and the push rod 430 can also be protected.

[0093] In one embodiment, see Fig.13 and Fig.14 The driving bracket 410 includes a supporting portion 411 and a second limiting portion 412. The through groove 4112 is arranged to penetrate the supporting portion 411 in the axial direction. The supporting surface 4111 is the end surface of the supporting portion 411 away from the piston 320. The second limiting portion 412 is formed on the supporting surface 4111 of the supporting portion 411. When the disc 421 is supported on the supporting surface 4111, the second limiting portion 412 is used to fit with a part of the outer circumference of the disc 421 to form a rotational fit with the disc 421. In addition, the second limiting portion 412 is formed with a notch corresponding to the outside of the disc 421. The notch is arranged to facilitate the user to rotate the disc 421.

[0094] Third, see Figures 1 to 3 The present application also provides an aerosol generating device, which includes an atomizer and a power supply assembly 100. The power supply assembly 100 is used to supply power to the atomizer, and the atomizer is used to heat and atomize the atomization matrix to form an aerosol after being powered on.

[0095] Specifically, the atomizer includes a driving assembly 400, a liquid storage assembly 300 and an atomizing assembly 200. The atomizing assembly 200 is electrically connected to a power supply assembly 100. The power supply assembly 100 is used to supply power to the atomizing assembly 200 so that the atomizing assembly 200 heats the atomizing medium and atomizes it to form an aerosol.

[0096] In one embodiment, the power supply assembly 100 includes a power supply bracket 110 and a battery and an electronic control unit housed in the power supply bracket 110, and the driving assembly 400, the liquid storage assembly 300 and the atomizing assembly 200 are sequentially detachably mounted on the outside of the power supply bracket 110. In this way, the driving assembly 400, the liquid storage assembly 300 and the atomizing assembly 200 are all detachable parts, so that each assembly can be manufactured, transported and sold separately, and each assembly is also convenient to disassemble, replace and maintain.

[0097] In one embodiment, see Figure 3 and Fig.15 The power supply bracket 110 includes a main body 111 and an extension portion 112 extending laterally from one end of the main body 111. A guide rail 1111 is formed on the side wall of the main body 111 facing the extension portion 112, and a slide groove that slides with the guide rail 1111 is formed on the side of the driving component 400, the liquid storage component 300 and the atomizing component 200. The driving component 400, the liquid storage component 300 and the atomizing component 200 are assembled on the extension portion 112 in sequence through the sliding cooperation between the guide rail 1111 and the slide groove. Among them, the cooperation between the guide rail 1111 and the slide groove can not only guide the driving component 400, the liquid storage component 300 and the atomizing component 200 to be assembled on the power supply bracket 110 in sequence, but also make the driving component 400, the liquid storage component 300 and the atomizing component 200 easy to disassemble and assemble, and also make the length dimension of the entire aerosol generating device relatively reduced.

[0098] Specifically, a first slide groove 346 is formed on the liquid storage bracket 340 of the liquid storage assembly 300 , a second slide groove 233 is formed on the atomization bracket 230 of the atomization assembly 200 , and a third slide groove 415 is formed on the driving bracket 410 of the driving assembly 400 .

[0099] In one embodiment, see Figure 3 The atomizer also includes a nozzle 500. During assembly, the atomizer component 200, the liquid storage component 300 and the drive component 400 are sequentially assembled to the extension portion 112 along the axial direction of the liquid storage chamber 313 through the cooperation of the guide rail 1111 and the slide groove. Finally, the plug 520 of the nozzle 500 is inserted into the socket 414 of the drive component 400 until the end faces of the nozzle 500 are respectively in contact with the top side surfaces of the drive bracket 410 and the main body 111, so that the atomizer component 200, the liquid storage component 300 and the drive component 400 can be axially limited by the nozzle 500 and the extension portion 112 to ensure the assembly stability and assembly sealing of each component.

[0100] In one embodiment, see Figure 3 After being assembled, the suction nozzle 500 also abuts against the top side of the disc 421 , so that the disc 421 can be axially limited by the suction nozzle 500 and the supporting surface 4111 .

[0101] In one embodiment, see Figure 3 The atomizer further includes a nozzle 500, which is mounted on the driving assembly 400. The atomizing assembly 200 is formed with an atomizing chamber 250, the liquid storage assembly 300 is formed with a first air guide channel 342 communicating with the atomizing chamber 250, and the driving assembly 400 is formed with a second air guide channel 413 communicating between the first air guide channel 342 and the nozzle 500. The aerosol generated in the atomizing chamber 250 can be introduced into the nozzle 500 via the first air guide channel 342 and the second air guide channel 413 in sequence.

[0102] In one embodiment, see Figure 3 The liquid storage assembly 300 further includes a liquid storage bracket 340, which is formed with a first air guide channel 342, an air inlet hole 344, and a connecting groove 343. The connecting groove 343 is in communication with the atomizing chamber 250, and the connecting groove 343 is connected between the first air guide channel 342 and the air inlet hole 344.
