[0072] As shown in Figure 5 When the valve 22 is moved to the second position relative to the second shell 21, the second liquid guide part 210 is in communication with the second storage cavity 201, which is equivalent to the second liquid guide part 210 being opened by the valve 22, so that the first storage cavity 101 of the atomizer 1 can be in communication with the second storage cavity 201 of the liquid reservoir 2 through the first liquid guide part 110 and the second liquid guide part 210, so as to guide the atomized liquid in the second storage cavity 201 into the first storage cavity 101 for replenishment.

[0073] In the present embodiment, it should be noted that in specific implementation, the first side wall 111 can be the top wall of the first shell 11, or the bottom wall of the first shell 11, or the circumferential side wall (such as the front side wall, the rear side wall, the left side wall or the right side wall of the first shell 11) of the first shell 11 between the top wall and the bottom wall of the first shell 11, which can be determined according to actual use needs, and the present embodiment does not make specific limitations thereon. Similarly, the second side wall 211 can be the top wall of the second shell 21, or the bottom wall of the second shell 21, or the circumferential side wall of the second shell 21.

[0076] In the embodiment, it also needs to be further explained that, in the implementation, the structure of the first liquid guide part 110 can be a hole structure, and the structure of the second liquid guide part 210 can be a plug structure; or the structure of the first liquid guide part 110 can be a plug structure, and the structure of the second liquid guide part 210 can be a hole structure; or the structure of the first liquid guide part 110 and the structure of the second liquid guide part 210 are both hole structures; or the structure of the first liquid guide part 110 and the structure of the second liquid guide part 210 are both plug structures; as long as the first storage cavity 101 and the second storage cavity 201 can be communicated with each other when the first liquid guide part 110 and the second liquid guide part 210 are connected and the valve 22 is in the second position, the specific structure of the first liquid guide part 110 and the second liquid guide part 210 is not limited in the embodiment. In some specific application scenarios, in order to make the connection between the first liquid guide part 110 and the second liquid guide part 210 more convenient and reliable, and considering that the atomizer 1 usually needs to be provided with a pierceable sealing body 14 (such as a silica gel film or an aluminum foil) at the first liquid guide part 110 when it is shipped from the factory to prevent the atomizing liquid pre-stored in the first storage cavity 101 from leaking from the first liquid guide part 110 when the atomizer 1 is stored and transported alone, therefore, optionally, the structure of the first liquid guide part 110 is a hole structure, and the structure of the second liquid guide part 210 is a plug structure, specifically, as shown in Figures 9-13 and Figure 17 the first liquid guide part 110 includes a liquid guide hole 1101, the liquid guide hole 1101 is provided with a pierceable sealing body 14, the second liquid guide part 210 includes a hollow liquid guide protrusion 2101, the liquid guide protrusion 2101 is inserted into the liquid guide hole 1101 and is in sealed communication with the first storage cavity 101 after piercing the sealing body 14, for the convenience of description, the related technical content below is described by taking the structure of the first liquid guide part 110 as a hole structure and the structure of the second liquid guide part 210 as a plug structure as an example. In order to realize the sealed communication between the liquid guide protrusion 2101 and the first storage cavity 101, prevent the atomizing liquid in the first storage cavity 101 from leaking to the outside through the cooperation gap between the liquid guide protrusion 2101 and the liquid guide hole 1101 after the atomizer 1 is combined with the liquid storage device 2 into an integrated whole, a sealing ring 27 can be arranged between the liquid guide protrusion 2101 and the liquid guide hole 1101, and the outer wall of the liquid guide protrusion 2101 is sleeved with the sealing ring 27 which is in contact with the first housing 11.

[0077] In the technical scheme of the embodiment, based on the above structure design, when the atomized liquid in the first storage cavity 101 of the atomizer 1 is consumed by the atomizing core 12, the valve 22 of the liquid reservoir 2 can be opened (i.e., the valve 22 is in the second position), so that the first storage cavity 101 of the atomizer 1 is in communication with the second storage cavity 201 of the liquid reservoir 2, and then the atomized liquid in the second storage cavity 201 of the liquid reservoir 2 can be introduced into the first storage cavity 101 of the atomizer 1 through the second liquid guide part 210 for replenishment. After the replenishment is completed, the valve 22 is closed (i.e., the valve 22 is in the first position), so that the first storage cavity 101 of the atomizer 1 is isolated from the second storage cavity 201 of the liquid reservoir 2, avoiding the atomized liquid in the first storage cavity 101 from flowing back to the second storage cavity 201. That is, the liquid reservoir 2 can replenish the atomized liquid for the atomizer 1 after the atomized liquid stored in the atomizer 1 is consumed by the atomizing core 12, so that the atomizer 1 can be repeatedly used, and the endurance of the electronic atomization device can be improved. That is, the electronic atomization device provided in the embodiment has the advantage of long sustainable use time. It should be noted that, since the connection between the first shell 11 and the second shell 21 is detachable, when the atomized liquid in the atomizer 1 and the liquid reservoir 2 is used up, the liquid reservoir 2 can be detached from the atomizer 1, and then a new liquid reservoir 2 preloaded with atomized liquid can be combined with the original atomizer 1 to continue to replenish the atomized liquid for the original atomizer 1.

[0078] Further, please refer to Figure 6 In some optional embodiments of the present application, the volume of the second storage cavity 201 can be set to 2.5-5.5 times the volume of the first storage cavity 101. For example, assuming that the volume of the first storage cavity 101 of the atomizer 1 is 2ML (i.e., capable of storing 2ML of atomized liquid), the volume of the second storage cavity 201 of the liquid reservoir 2 can be 5ML-11ML, i.e., the volume of the atomizer 1 is indirectly increased by 2.5-5.5 times. In this way, the liquid reservoir 2 can repeatedly replenish the atomized liquid for the atomizer 1 (at least 3 times), and the volume of the liquid reservoir 2 is not set too large, so that the overall volume of the electronic atomization device is not too large, and the convenience of carrying for the user is not affected.

[0079] Further, please refer to Figures 3-4 and Figures 18-21In some optional embodiments of the present application, the first side wall 111 is a circumferential side wall of the first shell 11, and the second side wall 211 is a circumferential side wall of the second shell 21. For example, the first side wall 111 is a right side wall of the first shell 11, and the second side wall 211 is a left side wall of the second shell 21. The second shell 21 further includes a third side wall 216 located at a position different from the second side wall 211, and the third side wall 216 is provided with a through hole portion 2160. The electronic atomization device further includes a driving component 32 arranged corresponding to the through hole portion 2160. The through hole portion 2160 is in communication with the mounting cavity 202 and is used for allowing at least part of the driving component 32 to extend into. The driving component 32 is arranged to be operable to cause the valve 22 to move between the first position and the second position.

[0080] In the present embodiment, the arrangement of the driving component 32 can facilitate the user to operate the valve 22 to move between the first position and the second position. Specifically, after the atomized liquid in the first storage cavity 101 of the atomizer 1 is consumed, the entire electronic atomization device can be first inverted (at this time, the suction nozzle 13 faces downward), and then a first operation is performed on the driving component 32, so that the driving component 32 drives the valve 22 to move from the first position to the second position. At this time, under the action of gravity, the atomized liquid in the second storage can be guided into the first storage through the second liquid guiding portion 210 for replenishment. After the replenishment is completed, a second operation is performed on the driving component 32, so that the valve 22 moves from the second position to the initial first position. At this time, the first storage cavity 101 and the second storage cavity 201 are isolated by the valve 22, so as to prevent the atomized liquid in the first storage cavity 101 from flowing back to the second storage cavity 201.

[0081] Further, in some optional embodiments of the present application, the valve 22 can have the following structure:

[0082] Please refer to Figures 3-6 The second shell 21 has a partition portion 217 located between the mounting cavity 202 and the second storage cavity 201. The partition portion 217 is provided with a liquid passing hole 2170 in communication with the second storage cavity 201. The valve 22 includes a sliding plate 221 slidingly connected in the mounting cavity 202. The sliding plate 221 is provided with a communication hole 2210 for communicating the second liquid guiding portion 210 and the second storage cavity 201. As shown in Figure 3 When the sliding plate 221 is not driven by the driving component 32 and is in the first position, the sliding plate 221 covers the liquid outlet end of the liquid passing hole 2170 and the liquid inlet end of the second liquid guiding portion 210 at the same time, so as to isolate the second liquid guiding portion 210 from the second storage cavity 201, and further isolate the first storage cavity 101 from the second storage cavity 201. As shown in Figure 5As shown, when the sliding plate 221 is driven by the driving component 32 to slide to the second position, the communication hole 2210 of the sliding plate 221 is in communication with the liquid outlet end of the liquid passing hole 2170 and the liquid inlet end of the second liquid guiding part 210 at the same time, so that the second liquid guiding part 210 is in communication with the second storage cavity 201, so as to guide the atomized liquid in the second storage cavity 201 into the first storage cavity 101 for replenishment. In this embodiment, the valve 22 has the advantages of simple structure.

[0083] Further, please refer to Figures 3-4 , Figure 8 and 20-21, in some optional embodiments of the present application, the liquid storage device 2 further comprises a first elastic member 23 located in the mounting cavity 202, one end of the first elastic member 23 is in abutment with the cavity wall of the mounting cavity 202, and the other end is in abutment with the sliding plate 221, and the first elastic member 23 is arranged to drive the sliding plate 221 to return to the first position when the driving component 32 removes the force applied to the sliding plate 221.

[0084] In this embodiment, the arrangement of the first elastic member 23 enables the sliding plate 221 to automatically return to the first position when the replenishment of the atomized liquid in the first storage cavity 101 is completed and the driving component 32 removes the force applied to the sliding plate 221, without the need for the user to separately reset the sliding plate 221, thereby facilitating the improvement of the user's experience. In specific implementation, the elastic member can be a spring, a spring piece, an elastic band, or other elements with good elastic properties, as long as it can meet the use requirements, and the present embodiment does not make specific limitations thereto.

[0085] Further, in some optional embodiments of the present application, in order to avoid the atomized liquid from seeping into the mounting cavity 202 through the mounting gap between the sliding plate 221 and the mounting cavity 202 during the process of replenishing the atomized liquid in the second storage cavity 201 into the first storage cavity 101, thereby causing the waste of the atomized liquid, please refer to Figure 13 and Figure 15 The side of the sliding plate 221 facing the liquid passing hole 2170 is fixed with a first sealing member 25 arranged around the liquid inlet end of the communication hole 2210, and the side of the sliding plate 221 facing the second liquid guiding part 210 is fixed with a second sealing member 26 arranged around the liquid outlet end of the communication hole 2210, and the first sealing member 25 and the second sealing member 26 are in contact with the cavity wall of the mounting cavity 202.

[0086] In the embodiment, it is to be explained that, in the specific implementation, the material of the first sealing member 25 can be a sealing material of the type of silica gel, rubber, silicone rubber, etc., and the first sealing member 25 can be fixed to the side of the sliding plate 221 facing the liquid passing hole 2170 in a manner of inlaying; similarly, the material of the second sealing member 26 can also be a sealing material of the type of silica gel, rubber, silicone rubber, etc., and the second sealing member 26 can also be fixed to the side of the sliding plate 221 facing the second liquid guiding part 210 in a manner of inlaying. In addition, in order to better avoid the atomized liquid from penetrating into the installation cavity 202 through the installation gap between the sliding plate 221 and the installation cavity 202, thereby causing the waste of the atomized liquid and causing the second elastic member 325 to be corroded by the atomized liquid, preferably, the first sealing member 25 and the second sealing member 26 are both arranged to extend along the sliding direction of the sliding plate 221 (i.e., the height direction of the sliding plate 221), so that the inner side walls of the installation cavity 202 located on the upper and lower sides of the liquid outlet end of the liquid passing hole 2170 are both in contact with the first sealing member 25, and the inner side walls of the installation cavity 202 located on the upper and lower sides of the liquid inlet end of the second liquid guiding part 210 are both in contact with the second sealing member 26, no matter whether the sliding plate 221 is in the first position or the second position.

[0087] Further, in some optional embodiments of the present application, the driving member 32 can be arranged in the liquid reservoir 2 (in this case, the driving member 32 belongs to a part of the liquid reservoir 2), and the structure of the driving member 32 can be a hand pushing structure. Specifically, please refer to Figures 18-21 The driving member 32 comprises a second hand pushing member 24 arranged on the second shell 21 in an exposed manner, and the second hand pushing member 24 is slidingly connected to the through hole part 2160 of the second shell 21 and connected to the sliding plate 221.

[0088] In the present embodiment, it is to be noted that the specific structural form of the second push member 24 can be a manually pressed push button or a manually side-sliding push button, which can be determined according to the specific arrangement of the slide plate 221. For example, when the slide plate 221 is arranged to slide up and down along the height direction of the second housing 21, the second push member 24 can be a push button exposed to the front side wall or the rear side wall of the second housing 21 (in this case, the third side wall 216 of the second housing 21 is the front side wall or the rear side wall of the second housing 21, the first elastic member 23 can be clamped between the upper side surface of the slide plate 221 and the top wall of the mounting cavity 202, and when the slide plate 221 is in the first position, the communication hole 2210 is located below the first liquid guide portion 110), or a push button exposed to the top wall of the second housing 21 (in this case, the first elastic member 23 can be clamped between the lower side surface of the slide plate 221 and the bottom wall of the mounting cavity 202, and when the slide plate 221 is in the first position, the communication hole 2210 is located above the first liquid guide portion 110). For another example, when the slide plate 221 is arranged to slide back and forth along the width direction of the second housing 21, the second push member 24 can be a push button exposed to the front side wall (or the rear side wall) of the second housing 21, in which case the first elastic member 23 is clamped between the rear side surface of the slide plate 221 and the rear side inner wall of the mounting cavity 202, and when the slide plate 221 is in the first position, the communication hole 2210 is located in front of the first liquid guide portion 110 (or the first elastic member 23 is clamped between the front side surface of the slide plate 221 and the front side inner wall of the mounting cavity 202, and when the slide plate 221 is in the first position, the communication hole 2210 is located behind the first liquid guide portion 110).

[0089] In the embodiment, for the convenience of illustrating the relevant structural principles, the second hand pushing piece 24 is taken as an example, which is a pushing key exposed to the front side wall of the second shell 21. Specifically, please refer to the drawings, after the atomizing liquid in the first storage cavity 101 of the electronic atomizing device 1 is consumed, the whole electronic atomizing device can be first inverted, and then the second hand pushing piece 24 is pushed by the finger in the direction close to the suction nozzle 13 (equivalent to the first operation mentioned in the foregoing embodiment), so that the sliding plate 221 is slid from the first position to the second position. At this time, the communication hole 2210 of the sliding plate 221 is in communication with the liquid passing hole 2170 and the second liquid guiding part 210 respectively, and the first elastic piece 23 is in a compressed state. Then, under the action of gravity, the atomizing liquid in the second storage cavity 201 can be guided into the first storage cavity 101 for replenishment through the liquid passing hole 2170, the communication hole 2210 and the second liquid guiding part 210 in sequence. After the replenishment is completed, the finger is released, and under the action of the elastic restoring force of the first elastic piece 23, the sliding plate 221 is automatically reset to the first position and drives the second hand pushing piece 24 to reset to the initial position. At this time, the first storage cavity 101 and the second storage cavity 201 are isolated by the sliding plate 221, so as to prevent the atomizing liquid in the first storage cavity 101 from flowing back to the second storage cavity 201. It should be noted that in some application scenarios, if the first elastic piece 23 is cancelled, after the atomizing liquid in the second storage cavity 201 is replenished into the first storage cavity 101, the second hand pushing piece 24 needs to be reset to the initial position by the finger, so as to reset the sliding plate 221 to the first position. That is, if the first elastic piece 23 is cancelled, the user needs to reset the sliding plate 221 separately.

[0090] Further, in some other optional embodiments of the present application, the driving part 32 can be arranged in the atomizing body (in this case, the driving part 32 belongs to the atomizing body, and specifically belongs to a part of the power supply assembly 3 in the atomizing body), and the structure of the driving part 32 can be a hand pushing structure, which is specifically as follows:

[0091] Please refer to Figures 1-6, the atomization main body further comprises a power supply assembly 3, the power supply assembly 3 comprises a battery 33, a control circuit board 34 and a third shell 31, the battery 33 and the control circuit board 34 are both installed in the third shell 31, the control circuit board 34 is electrically connected with the battery 33 and the atomization core 12 respectively, the control circuit board 34 can control the battery 33 to supply power for the atomization core 12, so that the atomization core 12 can be powered to perform atomization work; one end of the third shell 31 along the height direction of the third shell 31 (i.e. the upper end of the third shell 31) is connected with the first shell 11 and detachably connected with the second shell 21 respectively, the third side wall 216 of the second shell 21 is the bottom wall of the second shell 21, and the part of the third shell 31 facing the third side wall 216 is provided with a through hole 3103; the driving component 32 comprises a first hand pushing piece 321, a push rod 324, a second elastic piece 325 for resetting the push rod 324 and a lever 322 rotatably installed in the third shell 31 (exemplarily, a rotating shaft 323 is fixed in the third shell 31, and the lever 322 is rotatably sleeved on the rotating shaft 323), the first hand pushing piece 321 has a hand pushing part 3211 and a rod part 3212 connected into one body, the hand pushing part 3211 is slidingly connected to the outer side wall of the third shell 31 outwardly along the height direction of the third shell 31, one end of the rod part 3212 away from the hand pushing part 3211 abuts against one end of the lever 322, the push rod 324 is slidingly installed in the third shell 31 along the height direction of the third shell 31 (exemplarily, a longitudinally arranged mounting sleeve 326 is arranged in the third shell 31, and the push rod 324 is longitudinally slidingly fitted in the mounting sleeve 326), one end of the push rod 324 abuts against one end of the lever 322 away from the rod part 3212 (exemplarily, a side wall of the mounting sleeve 326 is provided with an opening 3260 facing the lever 322 and longitudinally extending, and one end of the lever 322 away from the rod part 3212 passes through the opening 3260 to abut against the lower end of the push rod 324), the other end of the push rod 324 is arranged corresponding to the through hole 3103 (in a specific implementation, when the push rod 324 is in an initial position, the upper end of the push rod 324 can extend into the through hole 3103 or can be arranged corresponding to the lower end of the through hole 3103), the through hole 3103 is communicated with the through hole part 2160 corresponding and is used for the end of the push rod 324 away from the lever 322 to pass through, one end of the second elastic piece 325 is fixed relative to the third shell 31, and the other end is fixed relative to the push rod 324 (exemplarily, the push rod 324 is a stepped shaft structure, one end of the second elastic piece 325 abuts against the upper inner wall of the mounting sleeve 326, and the other end of the second elastic piece 325 abuts against one of the stepped surfaces of the push rod 324 arranged away from the lever 322); when the hand pushing part 3211 is driven by external force to drive the lever 322 to rotate, the end of the push rod 324 away from the lever 322 abuts against the sliding plate 221 after passing through the through hole 3103 and extending into the through hole part 2160, so as to drive the sliding plate 221 to slide from the first position to the second position.

[0092] In this embodiment, based on the above structural design, after the atomizing liquid in the first storage chamber 101 of the atomizer 1 is consumed by the atomizing core 12, the entire electronic atomizing device can be inverted, and then the pusher part 3211 of the first pusher 321 can be pushed with a finger in the direction away from the mouthpiece 13 (equivalent to the first operation mentioned in the previous embodiment). During the process of pushing the pusher part 3211, the rod part 3212 of the first pusher 321 drives the lever 322 in a clockwise direction (e.g., Figure 6 As shown, the lever 322 rotates, and simultaneously, the lever 322 pries the push rod 324 to slide along the direction close to the slide plate 221. During the sliding of the push rod 324 along the direction close to the slide plate 221, the end of the push rod 324 away from the lever 322 first passes through the through hole 3103 and then extends into the through hole 2160 of the second housing 21, and then abuts against the slide plate 221, thereby pushing the slide plate 221 to slide along the direction away from the through hole 2160 until the slide plate 221 slides to the second position. When the slide plate 221 slides to the second position, the connecting hole 2210 of the slide plate 221 is connected to the liquid passage hole 2170 and the second liquid guiding part 210 respectively, and the first elastic member 23 is in a compressed state, and the push part 3211 is in a state where it can no longer slide along the direction away from the suction nozzle 13, and then under the action of gravity The atomized liquid in the second storage can be sequentially introduced into the first storage through the liquid passage 2170, the connecting hole 2210, and the second liquid guiding part 210 for replenishment. After replenishment, the finger is released (equivalent to the second operation mentioned in the previous embodiment) to remove the force applied to the slide plate 221 by the push rod 324. During this process, under the action of the elastic restoring force of the second elastic member 325, the push rod 324 is reset to the initial position and drives the lever 322 and the push part 3211 to be reset to the initial position simultaneously. At the same time, under the action of the elastic restoring force of the first elastic member 23, the slide plate 221 is automatically reset to the first position. At this time, the first storage cavity 101 and the second storage cavity 201 are isolated by the slide plate 221 to prevent the atomized liquid in the first storage cavity 101 from flowing back into the second storage cavity 201.

[0093] In this embodiment, it should be noted that, in specific implementation, the connection between the first housing 11 and the third housing 31 can be a detachable connection (such as a magnetic connection, threaded connection, snap-fit ​​connection, plug-in connection, etc.) or a non-detachable fixed connection (such as an integral connection), which can be determined according to actual usage needs. This embodiment does not impose specific limitations on this. As for the detachable connection between the second housing 21 and the third housing 31, it can specifically be a magnetic connection, snap-fit ​​connection, or plug-in connection. This embodiment also does not impose specific limitations on this.

[0094] In the present embodiment, compared with arranging the driving component 32 in the liquid reservoir 2, the present embodiment has the advantage that, after the atomized liquid in the liquid reservoir 2 is consumed, the driving component 32 can be retained in the power assembly 3 for repeated use, and will not be discarded with the replacement of the liquid reservoir 2.

[0095] Further, in some alternative embodiments of the present application, the driving component 32 can be arranged in the atomization body (in this case, the driving component 32 belongs to the atomization body, specifically to the power assembly 3 of the atomization body), and the structure of the driving component 32 can be an electric type, specifically as follows:

[0096] Please refer to Figures 8-11 and Figure 13 , the atomization body further comprises a power assembly 3, the power assembly 3 comprises a third shell 31, a battery 33, a control circuit board 34 and a control switch 35, one end of the third shell 31 along the height direction of the third shell 31 is connected with the first shell 11 and detachably connected with the second shell 21 respectively, the third side wall 216 is the bottom wall of the second shell 21, the part of the third shell 31 facing the third side wall 216 is provided with a through hole 3103, the battery 33 and the control circuit board 34 are both installed in the third shell 31, the control circuit board 34 is electrically connected with the battery 33, the control switch 35 and the atomization core 12 respectively, and the control switch 35 is at least partially exposed from the third shell 31; the driving component 32 comprises a linear motor 327 and a push rod 324, the linear motor 327 is installed in the third shell 31 and electrically connected with the control circuit board 34, the push rod 324 is slidingly installed in the third shell 31 along the height direction of the third shell 31 (exemplarily, a longitudinal installation sleeve 326 is arranged in the third shell 31, and the push rod 324 is at least partially longitudinally slidingly fitted in the installation sleeve 326), one end of the push rod 324 is fixedly connected with the output shaft of the linear motor 327, and the other end is arranged corresponding to the through hole 3103, the through hole 3103 is in communication with the through hole part 2160 and used for allowing the end of the push rod 324 away from the linear motor 327 to pass through.

[0097] In the present embodiment, it should be noted that the specific structure of the control switch 35 can be a button switch, a sliding switch, a touch switch, etc., which can be determined according to actual use needs, and the present embodiment does not make specific limitations thereon, and for the convenience of description, the present embodiment takes the structure of the control switch 35 as a sliding switch as an example for description. Specifically, after the atomized liquid in the first storage cavity 101 of the atomizer 1 is consumed by the atomization core 12, the entire electronic atomization device can be first inverted, and then the finger is used to slide along the first direction (such as the direction of arrow A in the figure) to control the atomization core 12 to start working. Figure 8The downward direction of the control switch 35 (equivalent to the first operation mentioned in the previous embodiment) causes the control circuit board 34 to control the output shaft of the linear motor 327 to extend in the direction close to the push rod 324, thereby pushing the push rod 324 to slide in the direction close to the slide plate 221. During the sliding process of the push rod 324 in the direction close to the slide plate 221, the end of the push rod 324 away from the linear motor 327 first passes through the through hole 3103 and then extends into the through hole 2160 of the second housing 21, and then abuts against the slide plate 221, thereby pushing the slide plate 221 to slide in the direction away from the through hole 2160 until the slide plate 221 slides to the second position. When the slide plate 221 slides to the second position, the connecting hole 2210 of the slide plate 221 is connected to the liquid passage hole 2170 and the second liquid guiding part 210 respectively, and the linear motor 327 is in a stopped state. Then, under the action of gravity, the mist in the second storage The atomized liquid can be sequentially introduced into the first storage chamber for replenishment through the liquid passage 2170, the connecting hole 2210, and the second liquid guiding part 210. After replenishment, the control switch 35 is slid along the second direction (which is opposite to the first direction mentioned above) with a finger (equivalent to the second operation mentioned in the previous embodiment) to remove the force applied to the slide plate 221 by the push rod 324. During this process, the control circuit board 34 controls the output shaft of the linear motor 327 to retract along the direction away from the push rod 324, thereby pulling the push rod 324 to slide along the direction away from the second housing 21 until the push rod 324 returns to the initial position. At the same time, under the action of the elastic restoring force of the first elastic member 23, the slide plate 221 automatically returns to the first position. At this time, the first storage chamber 101 and the second storage chamber 201 are isolated by the slide plate 221 to prevent the atomized liquid in the first storage chamber 101 from flowing back into the second storage chamber 201.

[0098] In this embodiment, compared to such Figures 18-21 Regarding the technical solution of the drive component 32 in the embodiment shown, which is a push-type structure, this embodiment designs the drive component 32 as an electric structure. The advantage is that, in the process of replenishing the atomized liquid in the second storage cavity 201 to the first storage cavity 101, the user's finger does not need to maintain the force of pushing the push part 3211 for a long time, which helps to save the user's strength and improve the user experience.

[0100] Further, in some optional embodiments of the present application, the connection between the first shell 11 and the third shell 31 and the connection between the second shell 21 and the third shell 31 can all be detachable snap connections, specifically:

[0101] Please refer to Figure 3 , Figure 10 , Figure 13 , Figure 17 and Figures 26-27The first side wall 111 of the first shell 11 is provided with a first recess 114 and a first elastic buckle 113 made of plastic. One end of the first elastic buckle 113 is connected to the outer wall of the first shell 11 in an integrated manner, and the other end extends in a direction close to the bottom wall of the accommodating cavity 310 and is provided with a first buckle portion 1131 arranged away from the first recess 114. The first buckle portion 1131 is buckled in the first clamping hole 3101 and can form sliding contact with the hole wall of the first clamping hole 3101 (for example, the top wall surface of the first clamping hole 3101 is a first inclined surface arranged at an obtuse angle with the cavity wall of the accommodating cavity 310 away from the first side wall 111. Correspondingly, the first buckle portion 1131 has a second inclined surface arranged facing the first inclined surface).

In this process, the lower end of the first elastic buckle 113 and the lower end of the second elastic buckle 213 are deformed due to the extrusion of the cavity wall of the accommodating cavity 310, until the first buckle portion 1131 is opposite to the first clamping hole 3101 and the second buckle portion 2131 is opposite to the second clamping hole 3102, the lower end of the first elastic buckle 113 returns to its original state and the first buckle portion 1131 is buckled to the first clamping hole 3101, and the lower end of the second elastic buckle 213 returns to its original state and the second buckle portion 2131 is buckled to the second clamping hole 3102, thereby realizing the mutual fixation between the first shell 11 and the third shell 31 and the mutual fixation between the second shell 21 and the third shell 31, so that the bottom of the entire combined atomizer can be stably retained in the accommodating cavity 310 of the third shell 31 and is not easy to be separated. When the atomization liquid in the liquid reservoir 2 is consumed and a new liquid reservoir 2 needs to be replaced, the bottom of the combined atomizer is pulled out of the accommodating cavity 310 of the third shell 31 by applying force with the hand, then the combined atomizer is pried open to separate the atomizer 1 from the old liquid reservoir 2, and then the above related assembly operation is repeated to combine the atomizer 1, the new liquid reservoir 2 and the power assembly 3 into a new electronic atomization device.
