[0045] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

Thus, the features defined with "first", "second", and "third" may explicitly or implicitly include at least one of such features. In the description of the present application, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined. All directional indications (such as up, down, left, right, front, back...) in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, then the directional indications will also change accordingly. In addition, the terms "include" and "have" and any variations thereof are intended to cover non - exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally further include steps or units not listed, or may optionally further include other steps or units inherent to these processes, methods, products, or devices.

[0047] References to "embodiments" in this specification mean that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0048] In the related art, after the liquid storage bottle is opened, if the liquid storage bottle is placed sideways or inverted, the aerosol generating matrix in the liquid storage bottle is likely to flow out. To this end, in some embodiments, a blocking member is provided at the liquid outlet of the liquid storage bottle to cover or expose the liquid outlet. However, the blocking member is likely to shake during movement and rub against the side wall of the liquid storage bottle; in addition, the blocking member is also likely to fall off the liquid storage bottle.

[0049] To this end, the embodiments of the present application provide a new liquid storage bottle. After the liquid storage bottle is opened, it can be resealed through the blocking member. When the blocking member is not affected by an external force, the liquid storage bottle will not leak liquid regardless of its posture; and the blocking member is not likely to shake and is not likely to fall off.

[0050] The present application will be described in detail below with reference to the drawings and embodiments.

[0051] Please refer to Figures 1 to 2 , Figure 1 which is a schematic diagram of the overall structure of the liquid storage bottle provided by an embodiment of the present application; Figure 2 is Figure 1 a cross-sectional view taken along the line A-A of the liquid storage bottle shown in ; in this embodiment, a liquid storage bottle 1 is provided. The liquid storage bottle 1 can be used to store or store an aerosol generating matrix 10. The aerosol generating matrix 10 can be a liquid such as e-liquid, water, liquid medicine, essence, beauty liquid, etc. The liquid storage bottle 1 includes a bottle body 11, a bottle cap 12, and a blocking assembly 13.

[0052] The bottle body 11 has a liquid storage cavity and a bottle mouth communicating with the liquid storage cavity. The liquid storage cavity is used to store the aerosol generating matrix 10. The bottle body 11 can be any structure having an accommodating space. The bottle cap 12 is provided on the bottle mouth so that the bottle mouth can be closed by the cover body 121, and a relatively sealed liquid storage cavity is formed in the bottle body 11 for accommodating the aerosol generating matrix 10.

[0053] In some embodiments, in combination with Figure 2 and Figure 3 , Figure 3 is Figure 1Schematic diagram of the overall structure of the bottle cap in the shown liquid storage bottle; the bottle cap 12 includes a cap body 121 and a guide frame 122. The cap body 121 covers the bottle mouth, and a part of the cap body 121 extends in a direction away from the liquid storage cavity and encloses an insertion hole 1210. The insertion hole 1210 can be a circular hole to facilitate the movement of the plugging assembly 13 therein. Of course, the insertion hole 1210 can also be an oval hole or a square hole, etc. In this application, a circular hole is taken as an example. In some embodiments, the cap body 121 is sleeved on the outer side of the bottle body 11. The cap body 121 and the bottle body 11 can be threadedly connected or snap-connected; of course, the cap body 121 and the bottle body 11 can also be integrally formed.

[0054] Combined with Figure 2 and Figure 3 , the guide frame 122 is fixed to the side of the cap body 121 facing the liquid storage cavity, and the guide frame 122 has a moving channel 1220 with one end open, and the moving channel 1220 can extend along the depth direction Y of the liquid storage bottle 1; the moving channel 1220 is coaxially arranged with and communicates with the insertion hole 1210; and the cross-sectional areas of the moving channel 1220 and the insertion hole 1210 are the same.

[0055] Among them, the moving channel 1220 has a bottom wall 1222 and side walls. At least one liquid outlet 1221 communicating with the liquid storage cavity is provided on the side wall of the moving channel 1220; the bottom wall 1222 of the moving channel 1220 faces the liquid storage cavity; a communication hole 1223 is provided on the bottom wall 1222 of the moving channel 1220. The aerosol generating matrix 10 in the liquid storage cavity flows out of the liquid storage cavity through the liquid outlet 1221 and provides the aerosol generating matrix 10 outward through the insertion hole 1210.

[0056] Among them, the number of the liquid outlets 1221 can be multiple, and the multiple liquid outlets 1221 are arranged at intervals along the circumferential direction of the moving channel 1220. In some specific embodiments, as Figure 3 shown, the guide frame 122 includes a bottom wall 1222 and a plurality of limiting strips 1224; one ends of the plurality of limiting strips 1224 are connected to the bottom wall 1222 at intervals along the circumferential direction of the bottom wall 1222 of the guide frame 122, and each limiting strip 1224 extends along the depth direction Y of the bottle body 11 and encloses to form the moving channel 1220. The other ends of the limiting strips 1224 are connected to the surface of the cap body 121 facing the liquid storage cavity along the circumferential direction of the insertion hole 1210, and the plurality of limiting strips 1224 are distributed at intervals along the circumferential direction of the insertion hole 1210, and each adjacent two limiting strips 1224 cooperate with the cap body 121 to form a liquid outlet 1221.

[0057] Among them, the number of the limiting strips 1224 can be three, and the three limiting holes are arranged at equal intervals along the circumferential direction of the insertion hole 1210; and the orthographic projection of the limiting strip 1224 on the cover body 121 can be located at the circumferential edge of the insertion hole 1210; the orthographic projection of the limiting strip 1224 on the bottom wall 1222 of the guide frame 122 is located at the edge position of the bottom wall 1222 of the guide frame 122.

[0058] Combined with Figure 4 , Figure 4 , FIG. Figure 4 is a schematic structural diagram of the plugging member connected to the bottle cap; the plugging assembly 13 includes a plugging member 131, the plugging member 131 passes through the communication hole 1223 and is movably connected to the moving channel 1220 to cover or expose the liquid outlet 1221. In this way, the communication hole 1223 can be used to guide the moving process of the plugging member 131, so as to reduce the risk that the plugging member 131 sways left and right or back and forth during the moving process and rubs against the plugging member 131. Specifically, the plugging member 131 can move towards the bottom wall 1222 of the moving channel 1220 under the action of an external force to expose the liquid outlet 1221; or move in the opposite direction under the action of an external force to cover the liquid outlet 1221. In this way, after the liquid storage bottle 1 is opened, the liquid outlet 1221 can be effectively plugged by moving the plugging member 131, so that the aerosol generating matrix 10 in the liquid storage bottle 1 will not overflow from the liquid outlet 1221, improving the self-sealing performance of the liquid storage bottle 1, so that the liquid storage bottle 1 will not leak liquid outward no matter how it is placed, saving the liquid volume in the liquid storage bottle 1, having good environmental protection and low use cost, and at the same time improving the safety and convenience in the assembly process of the liquid storage bottle 1. When the liquid storage bottle 1 needs to supply liquid, the plugging member 131 can be moved in the opposite direction to expose the liquid outlet 1221, so as to supply liquid to the outside.

[0059] In some embodiments, referring to Figure 5 , Figure 5 is Figure 1 a schematic diagram of the overall structure of the plugging member in the liquid storage bottle; the plugging member 131 includes a sliding portion 1311 and a contracting portion 1312. The sliding portion 1311 is slidably connected to the moving channel 1220 and the insertion hole 1210, and the cross-sectional area of at least a part of the sliding portion 1311 is not less than the cross-sectional area of the moving channel 1220 and not less than the cross-sectional area of the insertion hole 1210, so as to prevent the aerosol generating matrix 10 from flowing out of the insertion hole 1210 through the sliding portion 1311 during the moving process.

[0060] In a specific embodiment, the sliding portion 1311 includes a first sealing portion 1313 and a sliding rod 1314 , the first sealing portion 1313 is slidably connected to the moving channel 1220 and the insertion hole 1210 , and the cross-sectional area of ​​the first sealing portion 1313 is not less than the cross-sectional area of ​​the moving channel 1220 . In this way, along the liquid outlet direction of the liquid storage bottle 1, when the first sealing portion 1313 moves to the downstream of the liquid outlet 1221, for example, when the first sealing portion 1313 moves into the insertion hole 1210, the first sealing portion 1313 can block the insertion hole 1210 to prevent the aerosol generating matrix 10 flowing out of the liquid outlet 1221 from flowing out of the liquid storage bottle 1 through the insertion hole 1210; when the first sealing portion 1313 moves into the moving channel 1220, and at least a part of the liquid outlet 1221 and the insertion hole 1210 are located on the same side of the first sealing portion 1313, the liquid outlet 1221 can be directly connected to the insertion hole 1210, so that the aerosol generating matrix 10 in the liquid storage bottle 1 can flow out of the liquid storage bottle 1 through the liquid outlet 1221 and the insertion hole 1210.

[0061] In some embodiments, a first snap-fit ​​groove 1317 may be provided on the outer side of the first sealing portion 1313, and the first snap-fit ​​groove 1317 is arranged along the circumference of the first sealing portion 1313, and a first sealing ring 132 is arranged in the first snap-fit ​​groove 1317 to improve the sealing performance between the first sealing portion 1313 and the inner wall surface of the insertion hole 1210 when the first sealing portion 1313 moves into the insertion hole 1210. The first sealing ring 132 may be a rubber ring or a plastic ring. The number of the first snap-fit ​​groove 1317 and the first sealing ring 132 may be one or more, and one first snap-fit ​​groove 1317 may be provided with one first sealing ring 132.

[0062] The sliding rod 1314 is connected to the side of the first sealing portion 1313 facing the liquid storage chamber, and the cross-sectional area of ​​the sliding rod 1314 is smaller than the cross-sectional area of ​​the first sealing portion 1313 , so as to reduce the movement resistance of the blocking member 131 and facilitate the movement of the blocking member 131 in the moving channel 1220 .

[0063] The contraction portion 1312 is connected to the end of the sliding rod 1314 away from the first sealing portion 1313, and the contraction portion 1312 can be configured to a first state or a second state. When the contraction portion 1312 is configured to the first state, the positive projection of the contraction portion 1312 on the guide frame 122 is located in the connecting hole 1223; so that the blocking member 131 can pass through the connecting hole 1223, which facilitates the detachable connection between the blocking member 131 and the guide frame 122. When the contraction portion 1312 is configured to the second state, such as Figure 2 or Figure 4As shown, the part of the projection of the contraction part 1312 on the guide frame 122 is located outside the communication hole 1223. In this way, when the guide 131 is installed on the guide frame 122, at least part of the contraction part 1312 can be clamped to the outside of the bottom wall 1222 of the guide frame 122 (i.e., the side of the guide frame 122 facing away from the cover body 121), so as to clamp the plugging member 131 on the guide frame 122 through the contraction part 1312, thereby reducing the risk of the plugging member 131 falling out of the moving channel 1220.

[0064] In one embodiment, as Figure 5 shown, the contraction part 1312 includes at least two bending parts 1315 and at least two limiting parts 1316. The at least two bending parts 1315 are arranged at intervals along the circumferential direction of the sliding part 1311, and one end of the bending part 1315 is connected to the sliding part 1311, and the other end of the bending part 1315 is a free end; the free end can be bent towards the central axis Z of the sliding part 1311 under the action of an external force to configure the contraction part 1312 to the first state. After the external force is removed, the free end rebounds to the initial position under the action of its own elastic restoring force to configure the contraction part 1312 to the second state. The bending part 1315 can be multiple vertical bars or vertical plates.

[0065] One limiting part 1316 is provided on one side of each bending part 1315 facing away from the central axis Z of the sliding part 1311. When the contraction part 1312 is configured to the first state, the projections of all the limiting parts 1316 and all the bending parts 1315 on the guide frame 122 are located within the communication hole 1223, so that the plugging member 131 can freely pass through the communication hole 1223. When the contraction part 1312 is configured to the second state, at least part of the projection of at least some of the limiting parts 1316 on the guide frame 122 is located outside the communication hole 1223, so that the limiting parts 1316 can be clamped to the side of the guide frame 122 facing away from the cover body 121 to prevent the plugging member 131 from falling. Specifically, when the contraction part 1312 is configured to the second state, each limiting part 1316 abuts against the surface of the guide frame 122 on the side facing away from the cover body 121.

[0066] Among them, the number of the bending parts 1315 can be two, and the two bending parts 1315 are opposite and spaced apart along the radial direction of the sliding part 1311. The sliding part 1311 can be a cylinder, a prism or other irregular structures. If the sliding part 1311 is a prism or other irregular structures, its radial direction refers to any direction perpendicular to its central axis Z and passing through its central axis Z.

[0067] In some embodiments, when the contraction part 1312 is configured to the second state, as Figure 5As shown, the extending direction of the bending portion 1315 is parallel to the extending direction of the central axis Z of the sliding portion 1311, and the orthographic projection of each bending portion 1315 on the guiding frame 122 is located within the communication hole 1223.

[0068] In some other embodiments, as Figure 6 shown, Figure 6 FIG. is a schematic diagram of the position of the contraction portion in the second state and the guiding frame provided by an embodiment of the present application; when the contraction portion 1312 is configured to the second state, at least a part of the orthographic projection of at least some of the bending portions 1315 on the guiding frame 122 may be located outside the communication hole 1223. In this way, the bending portion 1315 can be further used to latch the plugging member 131, so as to further reduce the risk of the plugging member 131 falling off the guiding frame 122. In this embodiment, the contraction portion 1312 may include the limiting portion 1316 involved above, or may not include the limiting portion 1316.

[0069] In some embodiments, referring to Figure 2 and Figure 4 , the plugging assembly 13 further includes an elastic member 133; along the extending direction Y of the moving channel 1220, two ends of the elastic member 133 are respectively in contact with the bottom wall 1222 of the moving channel 1220 and the plugging member 131. Wherein, the plugging member 131 can move towards the bottom wall 1222 of the moving channel 1220 under the action of an external force, so that at least a part of the liquid outlet 1221 and the insertion hole 1210 are on the same side of the plugging member 131, thereby exposing the liquid outlet 1221 and compressing the elastic member 133; and after the external force is removed, under the action of the elastic restoring force for the elastic member 133 to restore its own initial state, the elastic member 133 drives the plugging member 131 to move in a direction away from the bottom wall 1222 of the moving channel 1220, so that the first sealing portion 1313 of the plugging member 131 is located downstream of the liquid outlet 1221, thereby plugging the liquid outlet 1221.

[0070] Among them, the elastic member 133 may be an elastic structure such as a spring or a coil spring.

[0071] In the above solution, when the aerosol - generating substrate 10 is contained in the liquid storage bottle 1, when the plugging member 131 is only affected by the elastic member 133, or when the force of the elastic member 133 acting on the plugging member 131 plays a dominant role, the force exerted by the elastic member 133 on the plugging member 131 can effectively plug the liquid outlet 1221, so that the aerosol - generating substrate 10 in the liquid storage bottle 1 will not overflow from the liquid outlet 1221, improving the self - sealing performance of the liquid storage bottle 1, enabling the liquid storage bottle 1 not to leak liquid outward regardless of its placement posture, saving the liquid volume in the liquid storage bottle 1, and improving the safety performance and assembly convenience during the assembly of the liquid storage bottle 1. When the applied external force is greater than the force of the elastic member 133, the plugging member 131 moves towards the bottom wall 1222 of the moving channel 1220, and the plugging member 131 opens the liquid outlet 1221 to supply liquid outward.

[0072] In some embodiments, as Figure 2 shown, the bottom wall 1222 of the moving channel 1220 is provided with a sleeving portion 1225. The sleeving portion 1225 extends towards the insertion hole 1210, and the communication hole 1223 penetrates through the sleeving portion 1225 along the extension direction Y of the moving channel 1220. In this solution, the moving process of the plugging member 131 can be guided by the sleeving portion 1225.

[0073] In this embodiment, the elastic member 133 is specifically sleeved outside the sleeving portion 1225 and the sliding rod 1314, and abuts against one surface of the first sealing portion 1313 facing the bottom wall 1222 of the moving channel 1220. In this way, the sleeving portion 1225 can limit the elastic member 133 to reduce the risk that the extension direction of the elastic member 133 changes during the compression process of the elastic member 133.

[0074] The liquid storage bottle 1 provided by the embodiment of the present application is provided with a plugging member 131, and the plugging member 131 is movably connected to the moving channel 1220 to cover or expose the liquid outlet 1221. Thus, after the liquid storage bottle 1 is opened, the liquid outlet 1221 can be effectively plugged by moving the plugging member 131. Therefore, when the plugging member 131 of the liquid storage bottle 1 is not under external force, the aerosol generating matrix 10 in the liquid storage bottle 1 will not overflow from the liquid outlet 1221, improving the self-sealing performance of the liquid storage bottle 1, ensuring that the liquid storage bottle 1 will not leak liquid outward regardless of its placement posture, saving the liquid volume in the liquid storage bottle 1, having better environmental protection and lower use cost. At the same time, the safety and convenience in the assembly process of the liquid storage bottle 1 are improved. When the liquid storage bottle 1 needs to supply liquid, the plugging member 131 can be moved in the opposite direction under external force to expose the liquid outlet 1221, so as to supply liquid to the outside. In addition, for the liquid storage bottle 1, by making the bottom wall 1222 of the moving channel 1220 face the side of the liquid storage cavity, a communication hole 1223 is provided in the bottom wall 1222 of the moving channel 1220, and the plugging member 131 passes through the communication hole 1223, so that the movement process of the plugging member 131 can be guided by the communication hole 1223.

[0075] See Figure 7 and Figure 8 , Figure 7 is a schematic diagram of the overall structure of the atomization mechanism provided by an embodiment of the present application; Figure 8 is Figure 7 the A-A sectional view of the atomization structure shown. In this embodiment, an atomization mechanism 2 is provided. The atomization mechanism 2 is used to communicate with the liquid storage bottle 1 and atomize the aerosol generating matrix 10 flowing out of the liquid storage bottle 1 when powered on to form an aerosol. Among them, the liquid storage bottle 1 is the liquid storage bottle 1 provided in any of the above embodiments; the atomization mechanism 2 includes: an atomization component 21, at least one liquid guide tube 22, and at least one thimble 23.

[0076] The atomization component 21 is used to atomize the aerosol generating matrix 10 when powered on to form an aerosol. The side wall of the liquid guide tube 22 has a liquid inlet 221, and the liquid guide tube 22 is communicated with the atomization component 21 through the liquid inlet 221 to supply liquid to the atomization component 21. Each liquid guide tube 22 is provided with a thimble 23.

[0077] See Figure 9 and Figure 10 , Figure 9 is a schematic diagram of the overall structure after the liquid storage bottle 1 and the atomization mechanism 2 are assembled; Figure 10 is Figure 9Cross-sectional view of the structure shown in the A-A direction; the ejector pin 23 is used to abut against the plugging member 131 of the liquid storage bottle 1 and drive the plugging member 131 to move towards the bottom wall 1222 of the moving channel 1220, so as to expose at least part of the liquid outlet 1221, enabling the liquid storage cavity to communicate with the liquid guide tube 22 through the liquid outlet 1221 and the insertion hole 1210; furthermore, enabling the aerosol generating matrix 10 in the liquid storage cavity to flow out of the liquid guide tube 22 and enter the atomization assembly 21 through the liquid inlet 221 of the liquid guide tube 22.

[0078] In some embodiments, referring to Figure 8 , the atomization mechanism 2 further includes a base 24; the atomization assembly 21 and the liquid guide tube 22 are arranged on the base 24. The ejector pin 23 includes a second sealing portion 231 and an abutting portion 232.

[0079] Wherein, the cross-sectional area of the second sealing portion 231 is not less than the cross-sectional area of the liquid guide tube 22, and the second sealing portion 231 is slidably connected inside the liquid guide tube 22 to be configured to a first position or a second position. As shown in Figure 8 , when the second sealing portion 231 is in the first position, along the extension direction Y of the liquid guide tube 22, the second sealing portion 231 is spaced from the base 24 and is located on the side of the liquid inlet 221 away from the base 24 along the extension direction Y of the liquid guide tube 22; thus, the liquid inlet 221 can be blocked by the second sealing portion 231 to prevent the aerosol generating matrix 10 in the atomization assembly 21 from flowing back into the liquid guide tube 22 and causing a liquid leakage problem. When the second sealing portion 231 is in the first position, along the extension direction Y of the liquid guide tube 22, the distance between the second sealing portion 231 and the base 24 can be 3-7 mm; for example, 3 mm, 5 mm or 7 mm.

[0080] As shown in Figure 10 , when the ejector pin 23 is subjected to an external force, such as the pressure of the liquid storage bottle 1, the ejector pin 23 moves towards the base 24 to configure the second sealing portion 231 to the second position. Wherein, when the second sealing portion 231 is in the second position, the second sealing portion 231 abuts against the base 24 and is located on the side of the liquid inlet 221 close to the base 24 along the extension direction Y of the liquid guide tube 22; so that after the liquid storage bottle 1 and the atomization mechanism 2 are installed, the liquid inlet 221 and the liquid storage bottle 1 are on the same side of the second sealing portion 231, realizing effective communication between the two and ensuring that the aerosol generating matrix 10 in the liquid storage bottle 1 can enter the atomization assembly 21 through the liquid inlet 221.

[0081] The abutting portion 232 is provided on the surface of the second sealing portion 231 facing the liquid storage bottle 1, and is arranged at an interval from the inner wall surface of the liquid guide tube 22 to reduce the moving resistance of the thimble 23. The abutting portion 232 is used to abut against the plugging member 131 of the liquid storage bottle 1 to push the plugging member 131 towards the bottom wall 1222 of the moving channel 1220, so as to expose the liquid outlet 1221. The abutting portion 232 and the second sealing portion 231 can be integrally formed. The cross-sectional area of the abutting portion 232 gradually decreases in the direction away from the second sealing portion 231; in this way, during the process of the abutting portion 232 extending into the insertion hole 1210 to push the plugging member 131 to move, it can be avoided that due to the contact between the abutting portion 232 and the inner wall surface of the insertion hole 1210, the pushing resistance is too large, or even the problem of affecting the liquid discharge; and it can ensure that the abutting portion 232 has a certain support strength to reduce the risk of bending or breaking during the process of the abutting portion 232 abutting against the plugging member 131.

[0082] In some embodiments, please continue to refer to Figure 8 , a plurality of second clamping grooves are formed on the outer side of the second sealing portion 231; the plurality of second clamping grooves are arranged at intervals in the direction of the second sealing portion 231 facing the abutting portion 232, and each second clamping groove is arranged in a circle along the circumferential direction of the second sealing portion 231; that is, the second clamping groove is in a closed-loop shape. In this embodiment, the atomization mechanism 2 further includes a plurality of second sealing rings 25, and each second clamping groove is provided with a second sealing ring 25. The second sealing ring 25 is also in a closed-loop shape to seal each gap between the second sealing portion 231 and the liquid guide tube 22 along the circumferential direction of the second sealing portion 231. By providing a plurality of second sealing rings 25 in this embodiment, on the one hand, the sealing performance between the second sealing portion 231 and the liquid guide tube 22 can be improved, and on the other hand, the risk of shaking during the process of the thimble 23 abutting against the plugging member 131 can be reduced. Of course, the number of the second clamping grooves and the second sealing portion 231 can also be one each.

[0083] In a specific embodiment, the atomization mechanism 2 includes two liquid guide tubes 22 and two thimbles 23. A plurality of liquid inlet ports 221 are arranged at intervals along the circumferential direction of each liquid guide tube 22.

[0084] Of course, in other embodiments, the atomization mechanism 2 further includes structures such as electrodes, upper cover bodies, atomization nozzles, etc. These structures are the same as or similar to the relevant structures in the existing atomization mechanisms, and can achieve the same or similar technical effects, which will not be elaborated here.

[0085] See Figure 9 and Figure 10, in one embodiment, an atomizer 3 is further provided. The atomizer 3 includes a liquid storage bottle 1 and an atomization mechanism 2. The liquid storage bottle 1 is the liquid storage bottle 1 provided in any of the above embodiments, and the atomization mechanism 2 is the atomization mechanism 2 provided in any of the above embodiments. The liquid storage bottle 1 is detachably connected to the atomization mechanism 2 to facilitate timely replacement of the liquid storage bottle 1. Among them, after the liquid storage bottle 1 and the atomization mechanism 2 are installed, the thimble 23 of the atomization mechanism 2 abuts against the plugging member 131 of the liquid storage bottle 1, and at least part of the liquid outlet 1221 and the insertion hole 1210 are located on the same side of the plugging member 131. At least part of the liquid outlet 1221 of the liquid storage bottle 1 is communicated with the liquid inlet 221 of the liquid guide tube 22, so that the aerosol generating matrix 10 in the liquid storage bottle 1 can smoothly enter the atomization component 21 of the atomization mechanism 2. Among them, when the liquid storage bottle 1 and the atomization mechanism 2 are not installed, the plugging member 131 of the liquid storage bottle 1 plugs its liquid outlet 1221; the thimble 23 of the atomization mechanism 2 is spaced apart from the base 24.

[0086] In a specific embodiment, the atomization mechanism 2 includes two liquid guide tubes 22 and two thimbles 23. The number of the liquid storage bottles 1 can be two. One liquid storage bottle 1 corresponds to one thimble 23 and one liquid guide tube 22 to supply liquid to the atomization mechanism 2. Among them, each liquid storage bottle 1 is replaceable.

[0087] See Figure 11 and Figure 12 , Figure 11 is a schematic diagram of the overall structure of the aerosol generating device provided in an embodiment of the present application; Figure 12 is Figure 11 The A-A cross-sectional view of the aerosol generating device shown in. In this embodiment, an aerosol generating device is provided for atomizing an aerosol generating matrix 10 to form an aerosol. The aerosol generating device can be used in different fields, such as medical, beauty, and recreational inhalation fields.

The atomization mechanism 2 is the atomization mechanism 2 provided in the above embodiment, and the power supply host 4 is detachably connected to the atomization mechanism 2 for supplying power to the atomization mechanism 2.

[0088] In one embodiment, see Figure 12The power supply host 4 includes a bottom cover 41, an upper cover 42, a shell 43, an electrode, a circuit board and other structures. Among them, the bottom cover 41 forms a hollow structure, the upper cover 42 is covered on the bottom cover 41, and cooperates with the bottom cover 41 to form a receiving cavity, the power supply and the circuit board are arranged in the receiving cavity, one end of the electrode is electrically connected to the circuit board, and the other end extends to the outside of the upper cover 42 to contact and electrically connect with the atomization component 21 of the atomization mechanism 2. The shell 43 is sleeved outside the bottom cover 41 and the upper cover 42, and part of the shell 43 extends to the side of the upper cover 42 away from the bottom cover 41, so as to cooperate with the upper cover 42 to form a receiving groove 44, and the receiving groove 44 is used to accommodate the atomization mechanism 2 and the liquid storage bottle 1. Among them, part of the atomizer mechanism 2 is embedded in the receiving groove 44 and contacts the upper cover 42; and the ejector pin 23 of the atomizer mechanism 2 is located in the receiving groove 44; in this way, during the assembly process of the liquid storage bottle 1 and the atomizer mechanism 2, the alignment process between the insertion hole 1210 of the liquid storage bottle 1 and the ejector pin 23 can be limited by the groove wall of the receiving groove 44, so that the sealing member 131 of the liquid storage bottle 1 can quickly abut against the ejector pin 23.
