[0031] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0032] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0033] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0034] The embodiment of the present application provides a liquid storage device, which includes a shell and a movable part. A liquid storage cavity and a liquid guide channel connecting the liquid storage cavity with the outside of the shell are formed in the shell, and the liquid storage cavity is used to store aerosol matrix; the movable part can be movably arranged in the shell, and a first position and a second position are defined along the movable trajectory of the movable part; when the movable part is in the first position, the movable part closes the liquid guide channel between the liquid storage cavity and the outside of the shell, and the liquid storage cavity is not connected to the outside of the shell; when the movable part is in the second position, the movable part opens the liquid guide channel between the liquid storage cavity and the outside of the shell to connect the liquid storage cavity with the outside of the shell. Since the liquid storage device uses the movable position of the movable part to control the opening or closing of the liquid guide channel between the liquid storage cavity and the outside of the shell, the possibility of leakage of the liquid storage device before use is reduced, and the structure is simple and does not occupy additional space. It will be explained in detail below.

[0035] See also Figures 1 to 11 The housing 11 of the liquid storage device 1 can be understood as a collection of related parts of the overall outline of the liquid storage device 1, which forms a liquid storage cavity 13 inside to accommodate the aerosol matrix. A movable part 12 is arranged in the housing 11. For the sake of convenience, the area in the housing 11 where the movable part 12 is arranged and allows the movable part 12 to move is also referred to as the receiving area 14.

[0036] In some embodiments, the liquid storage device may further include a bottle cap 151, which closes the connection between the shell 11 and the outside and blocks the external movement of the movable part 12 relative to the shell 11. In this embodiment, the shell 11 of the liquid storage device 1 may be a bottle-shaped structure, on which a bottle mouth structure 15 is formed. The movable part 12 may be arranged at the bottle mouth structure 15. When the liquid storage device 1 is arranged on the atomization device 2, its bottle mouth structure 15 is connected to the liquid replenishment port of the atomization device 2, so that the receiving area 14 is connected to the liquid storage space 212 of the atomization device 2. In order to ensure the sealing effect of the liquid storage device 1 and prevent the movable part 12 from escaping from the shell 11 to the outside during transportation, storage, etc., a bottle cap 151 is provided at the bottle mouth structure 15 to provide additional sealing, and the bottle cap 151 needs to be removed before use. In other embodiments, the housing 11 of the liquid storage device 1 may also be formed into other shapes, as long as a liquid storage cavity 13 capable of storing aerosol substrate is formed therein and the liquid storage cavity 13 can be communicated with the outside; in addition, the specific shape of the bottle cap 151 is not limited in this application. For the sake of convenience, the embodiments of this application are mainly described with reference to the liquid storage device 1 of a bottle-shaped structure.

[0037] The housing 11 may be a plurality of parts that can be separated and detachably assembled. When the parts of the housing 11 are assembled, the housing 11 may form a stable structure. In this embodiment, when the housing 11 is assembled, a liquid storage chamber 13 capable of storing aerosol matrix is ​​formed. In other embodiments, the housing 11 may also be an integral body, which is integrally formed by processes such as blow molding.

[0038] like Figure 1 As shown, as an example, the shell 11 may include a main shell 111 and an end cap 112, and a liquid storage chamber 13 is formed in the main shell 111. One end of the main shell 111 has an opening, and the end cap 112 is used to at least partially close the opening on the main shell 111, so that the liquid storage chamber 13 is formed as a sealable chamber, and the end cap 112 can be connected to the outside of the shell 11 by setting a receiving area 14. A bottle mouth structure 15 is formed on the end cap 112, and the bottle mouth structure 15 is a hollow tubular shape. The main shell 111 and the end cap 112 are detachably or non-detachably installed and connected. The hollow part of the bottle mouth structure 15 passes through the end cap 112 in its axial direction, and can connect the liquid storage chamber 13 and the outside of the shell 11, as the receiving area 14. The shell 11 is split into the main shell 111 and the end cap 112, and can be manufactured separately, simplifying the structure of each component.

[0039] In practical applications, the bottle mouth structure 15 can also make the liquid storage device 1 and the atomizing device 2 better docked, for example, it can extend into the interior of the atomizing device 2 to enhance the cooperation with the atomizing device 2, so as to have better installation stability and accuracy. A sealing structure 16 such as sealing silica gel can also be provided on the outer wall of the bottle mouth structure 15. When the liquid storage device 1 is arranged on the atomizing device 2, the sealing structure 16 on the outer wall of the bottle mouth structure 15 is sealed and matched with the inner wall of the accommodating space 211 of the atomizing device 2, reducing the possibility of leakage of the liquid storage device 1 after being installed on the atomizing device 2, and improving the installation stability of the liquid storage device 1.

[0040] A liquid conducting channel 17 is also formed in the shell 11, and the liquid conducting channel 17 is used to connect the liquid storage cavity 13 and the outside of the shell 11. That is to say, when the aerosol matrix stored in the liquid storage device 1 needs to be used, the aerosol matrix can be output to the outside of the shell 11 through the liquid conducting channel 17, for example, injected into the liquid storage space 212 in the atomization device 2 for storing the aerosol matrix. Exemplarily, the liquid conducting channel 17 can be formed by the shell 11 and the movable part 12; it can also be formed only on the movable part 12 provided in the shell, that is, the present application does not limit the specific formation method of the liquid conducting channel 17, as long as it can connect the liquid storage cavity 13 and the outside of the shell 11.

[0041] The movable part 12 can be understood as a part used to be arranged in the shell 11 and control the opening and closing of the liquid guide channel 17 between the liquid storage chamber 13 and the outside of the shell 11. The movable part 12 can move in the receiving area 14. Exemplarily, its movement can be translation, flipping, etc. Regardless of its movement form, in this application, the movement of the movable part 12 will change its position to a certain extent. When the movable part 12 is in different positions, it can affect the opening and closing of the liquid guide channel 17. The movable part 12 of this embodiment can be in at least two different positions, namely the first position and the second position. Among them, when the movable part 12 is in the first position, the liquid guide channel 17 is closed, and the aerosol matrix cannot flow outside the liquid storage device 1. When it is in the second position, the liquid guide channel 17 is opened, and the aerosol matrix can flow out through the liquid guide channel 17 to replenish the atomizing device 2. In actual use, the movable part 12 can be initially set to the first position to close the liquid guide channel 17, so that the liquid storage device 1 can be stored and transported separately.

[0042] It should be understood that the first position and the second position can be an exact position or a range. As long as the movable member 12 is still within the range corresponding to the first position, the liquid guiding channel 17 remains closed; the same is true for the second position. As long as the movable member 12 is within the range corresponding to the second position, the liquid guiding channel 17 will be opened.

[0043] In some embodiments, as long as the movable member 12 is not in the first position, the liquid guide channel 17 will be in an open state; it can also be understood that other positions except the first position can be regarded as the second position. In some embodiments, in addition to the first position and the second position, the movable member 12 can also have other position states, which is not limited by the present application.

[0044] In some embodiments, the second position is further away from the outside of the liquid storage device 1 than the first position, so that the movable member 12 can move toward the inside of the liquid storage device 1 under the direct action of external force, thereby reaching the second position to open the liquid guide channel 17. The control method of the movement of the movable member 12 is simplified. In practical applications, the movable member 12 can be abutted by an external structure to open the liquid guide channel 17. For example, an abutment member 231 can be provided in the atomization device 2, so that the liquid guide channel 17 is opened only when the liquid storage device 1 is installed to the atomization device 2, thereby preventing the liquid storage device 1 from leaking before being installed to the atomization device 2.

[0045] For some examples, see Figure 2 and Figure 3The movable part 12 includes a plug body 121 and a sealing part 122. The plug body 121 is the basic structure of the movable part 12. The plug body 121 is arranged along the axial direction of the receiving area 14 and can move along the axial direction of the receiving area 14. The sealing part 122 is arranged at one end of the plug body 121 close to the liquid storage chamber 13. The sealing part 122 protrudes from the surface of the plug body 121 in the circumferential direction of the receiving area 14. The sealing part 122 is used to block the receiving area 14 when the movable part 12 is in the first position, so that the liquid guide channel 17 is closed, and the surface of the sealing part 122 is basically flush with the lower surface of the end cover 112. Providing the sealing part 122 at the end of the plug body 121 can reduce the contact area between the movable part 12 and the inside of the receiving area 14, so that the movable part 12 is easier to move. Figure 3 Shown, indicated Figure 2 In the enlarged image of the middle area A, the sealing portion 122 protrudes circumferentially from the surface of the plug body 121 and can form an interference fit with the receiving area 14, forming an effective blockage to prevent the aerosol matrix from leaking out. When the movable part 12 moves to the second position in the liquid storage chamber 13, the sealing portion 122 can move to the outside of the receiving area 14. Or when the movable part 12 moves to the second position in the liquid storage chamber 13, the sealing portion 122 can move to a position where it cannot form an interference fit with the receiving area 14, for example, the inner diameter of the receiving area 14 increases in the direction close to the inside of the liquid storage chamber 13. Regardless of the form, when the sealing portion 122 cannot form an effective interference fit with the inner wall of the receiving area 14, the aerosol matrix can enter the receiving area 14.

[0046] In some embodiments, the sealing portion 122 may be an integral structure with the plug body 121, that is, the sealing portion 122 may be a portion of the plug body 121 with an increased outer diameter of the side wall. In other embodiments, the sealing portion 122 may also be a sealing silicone or other structure disposed on the plug body 121, and the sealing silicone or other structure cooperates with the inner wall of the receiving area 14 to form a seal.

[0047] The liquid-conducting channel 17 is a space formed based on the movable member 12 and capable of directly allowing the aerosol matrix to flow. The liquid-conducting channel 17 may be connected to the receiving area 14 , and at least partially located in the receiving area 14 .

[0048] As an example, the liquid guiding channel 17 is arranged inside the plug body 121, see Figure 2 and Figure 4As shown, the interior of the plug body 121 is not a solid structure, and a liquid conducting channel 17 is provided therein. The liquid conducting channel 17 has a liquid outlet 171 and a liquid inlet 172 that are connected. The liquid outlet 171 is located at one end of the plug body 121 away from the liquid storage chamber 13, and is used to communicate with the outside of the shell 11; the liquid inlet 172 is located on the side wall of the plug body 121. When the movable part 12 is in the first position, the liquid inlet 172 is located inside the receiving area 14, and the path between the liquid inlet 172 and the liquid storage chamber 13 is closed by the sealing part 122, and the aerosol matrix cannot enter the liquid conducting channel 17. When the movable part 12 is in the second position, the liquid inlet 172 is located in the liquid storage chamber 13. At this time, the liquid inlet 172 is directly moved outside the receiving area 14 and can be directly connected with the liquid storage chamber 13. The aerosol matrix in the liquid storage chamber 13 can enter the liquid guiding channel 17 through the liquid inlet 172 , and flow out from the liquid outlet 171 along the liquid guiding channel 17 , and finally flow to the outside of the housing 11 .

[0049] As another example, the liquid guide channel 17 is not formed in the movable member 12 itself, but is formed by the cooperation between the movable member 12 and the receiving area 14. Figure 5 and Figure 6 As shown, the outer diameter of the plug body 121 is smaller than the receiving area 14, so as to cooperate with the inner wall of the receiving area 14 to form a liquid conducting channel 17; the liquid conducting channel 17 has a liquid outlet 171 and a liquid inlet 172; the liquid outlet 171 is located at the end of the plug body 121 away from the liquid storage chamber 13, and is used to communicate with the outside of the shell 11. It can be understood that when the movable part 12 is in the first position, the liquid inlet 172 of the liquid conducting channel 17 is closed by the sealing part 122. When the movable part 12 is in the second position, since there is a gap between the plug body 121 and the inner wall of the receiving area 14, the plug body 121 will cooperate with the inner wall of the receiving area 14 at the end close to the liquid storage chamber 13 to form a liquid inlet 172, and the liquid inlet 172 is connected with the liquid outlet 171. In other embodiments, the liquid conducting channel 17 can also be in other forms.

[0050] In this embodiment, the movable member 12 can partially enter the liquid storage chamber 13, but does not completely escape from the receiving area 14. That is, the movable member 12 is always arranged in the receiving area 14 and will not fall into the liquid storage chamber 13. This can prevent the presence of arbitrarily movable foreign objects in the liquid storage chamber 13 and avoid affecting the user experience. The liquid guide channel 17 formed by the movable member 12 can also be used to control the flow rate of the aerosol matrix to the outside.

[0051] For example, see Figure 4For example, the aerosol matrix enters the liquid conducting channel 17 through the liquid inlet 172, so the maximum rate at which the aerosol matrix flows out of the liquid storage device 1 will be affected by the area of ​​the liquid inlet 172. The smaller the liquid inlet 172, the slower the rate at which the aerosol matrix flows outward (toward the outside of the shell 11). In practical applications, by controlling the opening size of the liquid inlet 172, the rate at which the aerosol matrix flows outward can be controlled at a required level. Of course, in addition to controlling the opening size of the liquid inlet 172, controlling the size of the cross-section of the rest of the liquid conducting channel 17 can also limit the flow rate of the aerosol matrix; specifically, the flow rate of the aerosol matrix is ​​mainly affected by the smallest cross-section in the liquid conducting channel 17.

[0052] See also Figure 6 Similarly, the flow rate of the aerosol matrix can be controlled by controlling the cross-sectional size of the liquid-conducting channel 17. The distance between the plug body 121 and the receiving area 14 corresponds to the cross-sectional size of the liquid-conducting channel 17. When the inner diameter of the receiving area 14 is constant, the outer diameter of the plug body 121 can determine the rate at which the aerosol matrix flows outward.

[0053] It can be seen that in some embodiments, the movable member 12 can not only keep the liquid storage device 1 sealed when the liquid storage device 1 is not in use, but also control the rate at which the aerosol matrix is ​​supplied to the liquid storage space 212 of the atomizing device 2 during the use of the liquid storage device 1. Controlling the outward flow rate of the aerosol matrix within a reasonable range can prevent a large amount of aerosol matrix from directly gushing out of the receiving area 14, thereby reducing the risk of leakage after the liquid storage device 1 is installed in the atomizing device 2.

[0054] In some embodiments, the movable member 12 further includes a limiting portion 123, which is located on the plug body 121, and is further away from the liquid storage chamber 13 than the sealing portion 122; the receiving area 14 further includes a limiting structure 143, which is used to cooperate with the limiting portion 123 to limit the movable member 12 to the second position. By providing the limiting portion 123 and the limiting structure 143, the movable member 12 is limited to the second position, so as to prevent the movable member 12 from completely escaping from the receiving area 14 and falling into the liquid storage chamber 13, and to ensure the stability of its position, which is conducive to the stable external supply of the aerosol matrix in the liquid storage device 1.

[0055] The limiting portion 123 and the limiting structure 143 can be configured to limit the movement of the movable part 12 in a single direction. For example, the limiting portion 123 and the limiting structure 143 can limit the movable part 12 to the first position to prevent the movable part 12 from falling off from the receiving area 14 to the outside of the shell 11 during transportation and the like. Exemplarily, the limiting structure 143 can be provided at one end of the receiving area 14 close to the outside of the shell 11 to form a block for the movable part 12. For another example, the limiting portion 123 and the limiting structure 143 can limit the movable part 12 to the first position. Exemplarily, when the movable part 12 continues to move in a certain direction, the limiting portion 123 and the limiting structure 143 will eventually form a match; at this time, the movable part 12 is in the second position and cannot continue to move in the original direction, so it can be limited to the second position; but the limiting portion 123 and the limiting structure 143 can be configured not to hinder the movement of the movable part 12 in the direction of the first position.

[0056] The limiting portion 123 and the limiting structure 143 can limit the movable part 12 to the first position and the second position; it should be understood that the movable part 12 can be limited to the first position and the second position means that the movable part 12 can be limited to the first position and the second position. In other words, it can prevent the movable part 12 from falling off to the outside of the shell 11, and it can also prevent the movable part 12 from falling into the liquid storage chamber 13. For example, the limiting structure 143 can be set at the position corresponding to the first position and the second position. As an example, the limiting structure 143 can include at least two sub-limiting structures, so that the movable part 12 is located between the two sub-limiting structures, when the limiting portion 123 of the movable part 12 cooperates with one of the sub-limiting structures, the movable part 12 is in the first position; when the limiting portion 123 of the movable part 12 cooperates with the other sub-limiting structure, the movable part 12 is in the second position.

[0057] In some other embodiments, the limiting portion 123 and the limiting structure 143 can be configured to limit the movement of the movable member 12 in both directions. For example, after the movable member 12 moves to the second position, the limiting portion 123 and the limiting structure 143 form a match, so that the movable member 12 cannot move in any direction, that is, it cannot return to the first position. Exemplarily, the limiting portion 123 and the limiting structure 143 can be snap-fitted, and when the movable member 12 is in the second position, the limiting portion 123 and the limiting structure 143 are snap-fitted, thereby preventing the movable member 12 from continuing to move.

[0058] In some embodiments, see Figure 7 and Figure 8As shown, the receiving area 14 includes a movable section 141 and a narrowing section 142. The movable section 141 is an area that allows the limiting portion 123 of the movable member 12 to move. In this embodiment, the limiting portion 123 protrudes from the surface of the plug body 121 in the radial or circumferential direction of the receiving area 14, and the maximum size of the limiting portion 123 in the radial direction of the receiving area 14 is not greater than the inner diameter of the movable section 141. The limiting portion 123 can be limited to be within the range of the movable section 141. It can be understood that when the limiting portion 123 protrudes from the surface of the plug body 121 in the circumferential direction of the receiving area 14, it means that the limiting portion 123 is arranged around the outer surface of the plug body 121. When protruding from the surface of the plug body 121 in the radial direction, the limiting portion 123 can be arranged in a local area of ​​the circumferential direction of the outer surface of the plug body 121, but not around the whole circle; for example, the limiting portion 123 can be arranged on two opposite sides.

[0059] The movable section 141 is further away from the liquid storage chamber 13 than the narrowing section 142, and the inner diameter of the movable section 141 is larger than the inner diameter of the narrowing section 142. The narrowing section 142 is an area that does not allow the limiting portion 123 to enter. In this embodiment, the maximum dimension of the limiting portion 123 in the radial direction of the receiving area 14 is larger than the inner diameter of the narrowing section 142, so the limiting portion 123 will not enter the narrowing section 142.

[0060] Due to the difference in the inner diameters of the movable section 141 and the narrowing section 142, a step surface 1431 can be formed at the junction of the movable section 141 and the narrowing section 142. When the limiting portion 123 is located at the junction of the movable section 141 and the narrowing section 142, it can abut against the step surface 1431 to limit the movable member 12 to the current position. In this embodiment, when the limiting portion 123 is located at the junction of the movable section 141 and the narrowing section 142, the movable member 12 is located at the second position. Figure 8 As shown, the step surface 1431 can be perpendicular to the inner wall of the receiving area 14; in other embodiments, the movable section 141 and the narrowed section 142 can also have a relatively smooth transition, for example, the step surface 1431 at the junction of the two can also be an inclined surface inclined at a certain angle, which is not perpendicular to the inner wall of the receiving area 14.

[0061] By setting the inner diameter of the receiving area 14 to change, the position of the limiting portion 123 can be limited when it abuts against the step surface 1431, which has a simple structure and is easy to process.

[0062] In some embodiments, a barrier layer 18 is disposed in the liquid storage chamber 13, such as Figures 9 to 11. The barrier layer 18 is used to prevent the aerosol matrix from flowing out of the receiving area 14. The barrier layer 18 is a structure arranged between the aerosol matrix and the receiving area 14, for example, it can be arranged at the port of the receiving area 14. The barrier layer 18 can be a completely sealed structure, or it can be not completely sealed, but it should avoid or hinder the passage of the aerosol matrix to a certain extent. When the movable part 12 is in the second position, the barrier layer 18 is punctured by the movable part 12, so that the aerosol matrix can be supplied to the outside. Exemplarily, the barrier layer 18 can be a film that does not penetrate the aerosol matrix. The provision of the barrier layer 18 can further prevent the aerosol matrix from leaking from the liquid storage device 1; and by utilizing the movement of the movable part 12, the barrier layer 18 is destroyed while the receiving area 14 is opened, without the need for additional operations, and the anti-leakage performance is increased without increasing the difficulty of use.

[0063] In order to puncture the barrier layer 18 more stably, in some embodiments, the movable member 12 includes a puncture portion 124, which is located at one end of the movable member 12 close to the barrier layer 18 in the axial direction of the receiving area 14. The puncture portion 124 can be a structure with a certain length and a sharp surface. When the movable member 12 is in the second position, the puncture portion 124 pierces the barrier layer 18 to destroy the barrier layer 18. The puncture portion 124 on the movable member 12 can be one or more, so as to destroy the barrier layer 18 to a greater extent and ensure that the aerosol matrix can flow out stably.

[0064] The present application also provides an atomizing device 2, see Figure 12 to Figure 13 The atomization device 2 includes a shell assembly 21 and an atomization assembly 22 .

[0065] The housing assembly 21 can be understood as a collection of related parts that constitute the overall outline of the atomizing device 2, and the housing assembly 21 can be formed with a cavity space to accommodate other components or other functional components required by the atomizing device 2. Exemplarily, the housing assembly 21 can be constructed by combining an outer shell, a structural member disposed inside the outer shell, etc.; with the help of the housing assembly 21, the user can carry, move, hold, and operate the atomizing device 2. The housing assembly 21 can be a plurality of parts that can be separated and detachably combined, and when the various parts of the housing assembly 21 are combined, the housing assembly 21 can form a stable structure.

[0066] The housing assembly 21 is formed with a receiving space 211 and a liquid storage space 212, and the receiving space 211 and the liquid storage space 212 are arranged in communication. The receiving space 211 is used to provide a placement space for the liquid storage device 1 so that the liquid storage device 1 can be set on the atomizing device 2, and the liquid storage device 1 stores an aerosol matrix; and the liquid storage space 212 is mainly used to store the aerosol matrix injected from the liquid storage device 1. In this embodiment, the receiving space 211 is used to accommodate the liquid storage device 1 of the above embodiment. The receiving space 211 can be a space located inside the housing assembly 21, or it can be an open space formed by the housing assembly 21.

[0067] In some embodiments, the liquid storage device 1 may have a larger liquid storage volume than the liquid storage space 212, so that the aerosol matrix can be injected into the liquid storage space 212 multiple times through the liquid storage device 1. For example, the volume of the liquid storage space 212 is 2 ml, and the volume of the liquid storage device 1 can be set to 10 ml or other parameters. In specific implementation, the contour shape of the accommodating space 211 can be set according to the specific shape of the liquid storage device 1. For example, the liquid storage device 1 can be a cylindrical bottle structure, and the accommodating space 211 can be a cylindrical space.

[0068] The shape of the accommodating space 211 can match the shape of the liquid storage device 1 . When the liquid storage device 1 is disposed in the accommodating space 211 , the liquid guide channel 17 can communicate with the liquid storage space 212 to inject aerosol matrix into the liquid storage space 212 .

[0069] In some embodiments, a trigger structure 23 is provided in the accommodating space 211, and the trigger structure 23 is used to move the movable member 12 of the liquid storage device 1 to the second position to open the liquid guide channel 17 between the liquid storage cavity 13 and the outside of the shell 11. Since the trigger structure 23 is provided in the accommodating space 211, the movable member 12 can be driven by the trigger structure 23 only after the liquid storage device 1 is set in the accommodating space 211 or during the process of being set in the accommodating space 211. Therefore, the liquid storage device 1 can open the liquid guide channel 17 when it is installed and used, avoiding leakage when it is not in use. The trigger structure 23 can be located at the connection between the accommodating space 211 and the liquid storage space 212, and is arranged corresponding to the position of the receiving area 14 of the liquid storage device 1.

[0070] The trigger structure 23 may be a movable structure or a fixed structure. The movable structure may drive the movable member 12 to move by its own movement, so that the movable member 12 moves to the second position. The fixed structure may abut against the movable member 12 during the process of the liquid storage device 1 being set in the accommodating space 211, so as to push the movable member 12 to move, so that the movable member 12 moves to the second position.

[0071] It should be noted that in some embodiments, the liquid storage device 1 may be a part of the atomizing device 2; in other embodiments, the atomizing device 2 may not be provided with the liquid storage device 1. In scenes such as factory delivery, transportation, and sales, the liquid storage device 1 and the atomizing device 2 may be packaged and stored separately; in scenes such as carrying and use, the user may place the liquid storage device 1 in the atomizing device 2 as needed. The liquid storage device 1 may be detachably combined with the housing assembly 21.

[0072] In some embodiments, see Fig.13 As shown, the atomizing device 2 includes the liquid storage device 1 of the above embodiment, and the trigger structure 23 includes an abutment member 231 fixedly arranged in the accommodating space 211. When the liquid storage device 1 is installed in the accommodating space 211, the abutment member 231 abuts against the movable member 12 from the end of the movable member 12 away from the liquid storage chamber 13, so that the movable member 12 is kept in the second position. The abutment member 231 can at least partially enter the interior of the receiving area 14, occupying the original position of the movable member 12, so that the movable member 12 is located at a position closer to the interior of the liquid storage chamber 13, that is, the second position. In this embodiment, the movable member 12 is configured to be able to move along the axial direction of the receiving area 14. Before the liquid storage device 1 is installed in the accommodating space 211, the movable member 12 is in the first position; during the process of installing the liquid storage device 1 to the accommodating space 211, the fixedly arranged abutment member 231 will push the movable member 12 to move along the axial direction of the receiving area 14 toward the direction close to the interior of the liquid storage chamber 13. The movement of the movable part 12 is controlled by the abutment part 231, and the movement of the movable part 12 will be completed during the process of installing the liquid storage device 1 into the accommodating space 211. It not only ensures that the liquid guide channel 17 will not be opened until the liquid storage device 1 is installed in the atomization device 2, thereby avoiding leakage of the aerosol matrix to a greater extent, but also does not increase additional operations and does not increase the difficulty of use for users.

[0073] In some embodiments, the trigger structure 23 further includes a connecting pipe 232. The connecting pipe 232 is used to connect the liquid guiding channel 17 and the liquid storage space 212, connect the liquid guiding channel 17 and the liquid storage space 212, and transport the aerosol matrix, so that the aerosol matrix can be accurately injected into the liquid storage space 212, reducing the possibility of leakage of the aerosol matrix from the atomization device 2. The connecting pipe 232 is arranged on the abutment member 231 and passes through the abutment member 231 along the axial direction of the receiving area 14; the connecting pipe 232 includes a first end and a second end, the first end is close to the movable member 12 in the axial direction of the receiving area 14, and the second end is away from the movable member 12 in the axial direction of the receiving area 14; the first end is connected to the liquid guiding channel 17, and the second end is connected to the liquid storage space 212.

[0074] The abutment member 231 may be a tubular structure, and an axially penetrating communication channel 232 is formed inside the abutment member 231. The outer diameter of the tubular structure may be the same as the inner diameter of the receiving area 14. When the liquid storage device 1 is installed in the receiving space 211, the abutment member 231 enters the receiving area 14, and its side wall abuts against the movable member 12. The communication channel 232 formed on the abutment member 231 is connected to the liquid guide channel 17, and the aerosol matrix will enter the communication channel 232 and be injected into the liquid storage space 212 along the communication channel 232.

[0075] The above structure can not only trigger the movement of the movable member 12 to open the liquid guiding channel 17, but also accurately connect with the liquid guiding channel 17 to ensure that the aerosol matrix is ​​accurately injected into the liquid storage space 212. The possibility of leakage of the aerosol matrix is ​​further reduced.

[0076] In other embodiments, the connecting pipe 232 may not be formed on the abutting member 231 , and the aerosol matrix may also enter the liquid storage space 212 through other paths after flowing out of the liquid guiding channel 17 .

[0077] The atomizing assembly 22 mainly plays the role of heating the aerosol matrix to generate aerosol. The atomizing assembly 22 is arranged in the liquid storage space 212 and is arranged in communication with the outside of the housing assembly 21. It can be understood that the housing assembly 21 has an airflow channel formed inside for airflow and aerosol to enter and exit. The airflow channel can generally include an air inlet channel, an atomizing channel, and an air outlet channel that are connected in sequence; and the atomizing assembly 22 constitutes the atomizing channel or the atomizing assembly 22 is arranged in the atomizing channel. The aerosol in the liquid storage space 212 is heated by the atomizing assembly 22, so that the generated aerosol can be discharged from the air outlet channel along with the airflow to be used. Fig.13 The dotted arrows in the figure indicate the direction of the airflow in the atomizing device 2.

[0078] In some embodiments, the atomizer device further includes a power supply device 24, which is electrically connected to the atomizer assembly 22 to supply power to the atomizer assembly 22. The power supply device 24 may be detachably combined with the housing assembly 21, and the power supply device 24 may be replaced depending on the usage. The power supply device 24 may be completely disposed inside the housing assembly 21, so that the housing assembly 21 may protect the power supply device 24.

[0079] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
