[0002] This application claims priority to Chinese Utility Model Patent Application No. 2024230232115, filed on December 6, 2024, entitled "Liquid Storage Device, Power Supply Device and Electronic Atomizing Device", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of electronic atomization technology, and in particular to a liquid storage device, a power supply device, and an electronic atomization device. Background Technology

[0004] An electronic atomizing device is an electronic device that can vaporize stored e-liquid, medicine, or other atomizing liquids into vapor through electric heating. An electronic atomizing device typically includes an atomizer and a power supply component. The atomizer generally includes a storage chamber for storing the atomizing liquid and an atomizing core for absorbing the atomizing liquid and vaporizing it into vapor. The power supply component is used to supply power to the atomizing core.

[0005] In related technologies, atomizers are generally pre-filled with atomizing liquid when they leave the factory. However, since the storage chamber of the atomizer is generally a closed structure and has a limited volume (usually 2ML), the lifespan of the atomizer is limited. Once the atomizing liquid in the storage chamber is consumed by the atomizing coil, the entire atomizer can only be discarded and cannot be reused. Utility Model Content

[0063] Please refer to Figures 1-3 and Figures 5-6 An electronic atomization device is provided in an embodiment of the present application, and the electronic atomization device comprises an atomization main body, a liquid reservoir 2, a first one-way valve 41 and a gas charging assembly 32, wherein:

[0064] The atomization main body comprises an atomizer 1, the atomizer 1 comprising a first shell 11 and an atomization core 12, the first shell 11 being provided with an airflow channel 102 and a first storage cavity 101 for storing atomization liquid, the first shell 11 having a first side wall 111 provided with a first liquid guide channel 1101 in communication with the first storage cavity 101; the atomization core 12 being mounted in the first shell 11 and in communication with the first storage cavity 101 (specifically, the cavity wall of the first storage cavity 101 is provided with a liquid outlet hole 1011 corresponding to the atomization core 12, the atomization core 12 being in communication with the first storage cavity 101 through the liquid outlet hole 1011), so that the atomization core 12 can suck atomization liquid from the first storage cavity 101 for heating and atomization to generate vapor for the user to smoke; moreover, the atomization core 12 is located on the airflow flow path of the airflow channel 102, so that the vapor generated by the atomization core 12 can be carried away by the suction airflow formed in the airflow channel 102 and discharged to the outside for the user to smoke; in addition, in order to facilitate the user to smoke, the top of the first shell 11 is connected with a suction nozzle 13 (the material of the suction nozzle 13 can be plastic) in communication with the airflow channel 102, when the user bites the suction nozzle 13 to smoke, the suction airflow can be formed in the airflow channel 102.

[0065] The liquid storage device 2 comprises a second shell 21, the second shell 21 being provided with a second storage cavity 201 for storing atomization liquid, the second shell 21 having a second side wall 211 provided with a second liquid guide channel 2101 in communication with the second storage cavity 201, the second side wall 211 being detachably connected with the first side wall 111 and the second liquid guide channel 2101 being in communication with the first liquid guide channel 1101.

[0066] The first one-way valve 41 is arranged on a path where the first liquid guide channel 1101 and the second liquid guide channel 2101 are communicated, and is used to communicate or isolate the first storage cavity 101 and the second storage cavity 201. Specifically, when the air pressure in the second storage cavity 201 is greater than a first preset threshold (i.e., the opening threshold of the first one-way valve 41) so that the first one-way valve 41 is in an open state, the path between the first liquid guide channel 1101 and the second liquid guide channel 2101 is opened, so that the first storage cavity 101 and the second storage cavity 201 are communicated. When the air pressure in the second storage cavity 201 is less than or equal to the first preset threshold so that the first one-way valve 41 is in a closed state, the path between the first liquid guide channel 1101 and the second liquid guide channel 2101 is closed, so that the first storage cavity 101 and the second storage cavity 201 are isolated. In specific implementation, the type of the first one-way valve 41 can be a spring type one-way valve (such as a ball type one-way valve, a conical one-way valve), a diaphragm one-way valve, or other types of one-way valves that are mature in the art. The present embodiment does not make specific limitations as long as the use requirements are met. Since the structure and principle of these one-way valves are known to those skilled in the art, they will not be described here.

[0067] The inflation assembly 32 is in communication with the second storage cavity 201, and is arranged to be operable to inflate the second storage cavity 201 with gas to open the first one-way valve 41 and drive the atomized liquid in the second storage cavity 201 into the first storage cavity 101.

[0068] In the present embodiment, it should be noted that in specific implementation, the first shell 11 can be an integrated structure, or a split structure assembled by different shell structures. Similarly, the second shell 21 can be an integrated structure, or a split structure assembled by different shell structures. The specific structure of the first shell 11 and the second shell 21 can be determined according to actual use needs, and the present embodiment does not make specific limitations.

[0069] In this embodiment, it should also be noted that, in specific implementation, the first sidewall 111 can be the top wall of the first housing 11, the bottom wall of the first housing 11, or a circumferential sidewall located between the top wall and the bottom wall of the first housing 11 (such as the front sidewall, rear sidewall, left sidewall, or right sidewall of the first housing 11). It can be determined according to actual usage needs, and this embodiment does not impose specific limitations on it. Similarly, the second sidewall 211 can be the top wall of the second housing 21, the bottom wall of the second housing 21, or a circumferential sidewall of the second housing 21. It can be understood here that when the first sidewall 111 is the bottom wall of the first housing 11, the second sidewall 211 is the top wall of the second housing 21; similarly, when the first sidewall 111 is the top wall of the first housing 11, the second sidewall 211 is the bottom wall of the second housing 21; similarly, when the first sidewall 111 is a circumferential sidewall of the first housing 11, the second sidewall 211 is a circumferential sidewall of the second housing 21, for example, as... Figures 7-10 As shown, the first sidewall 111 is the right sidewall of the first housing 11, and the second sidewall 211 is the left sidewall of the second housing 21. It should be noted that, in specific implementations, the detachable connection between the first sidewall 111 and the second sidewall 211 can be a snap-fit ​​connection or a magnetic connection (specifically, a magnetic connection between the first sidewall 111 and the second sidewall 211 can be achieved by setting magnets on the first sidewall 111 and the second sidewall 211), as long as it meets the usage requirements. This embodiment does not impose specific limitations in this regard. For example, as... Figures 7-10 As shown, the detachable connection between the first sidewall 111 and the second sidewall 211 is a snap-fit ​​connection. Specifically, the first sidewall 111 has at least one snap-fit ​​element 112 protruding from it, and the second housing 21 has a frame portion 212 surrounding the second sidewall 211. The inner wall of the frame portion 212 has at least one slot 2120, and each snap-fit ​​element 112 is engaged with each slot 2120 in a one-to-one correspondence. It should also be noted that the first sidewall 111 and the second sidewall 211 can be flat, curved, or formed by connecting flat and curved surfaces, or formed by connecting different flat surfaces, depending on the actual use requirements. This embodiment does not impose specific limitations on the specific structural form of the first sidewall 111 and the second sidewall 211.

[0070] In the embodiment, based on the above structural design, when the atomized liquid in the first storage cavity 101 of the atomizer 1 is consumed by the atomizing core 12, the gas charging assembly 32 can be operated to charge gas into the second storage cavity 201 of the liquid reservoir 2, so that the gas pressure in the second storage cavity 201 increases. When the gas pressure in the second storage cavity 201 is greater than the first preset threshold, the first one-way valve 41 opens and the first storage cavity 101 and the second storage cavity 201 are communicated, so that the atomized liquid in the second storage cavity 201 can be guided into the first storage cavity 101 in sequence through the second liquid guiding passage 2101 and the first liquid guiding passage 1101 under the action of the gas pressure, wherein in the process of guiding the atomized liquid in the second storage cavity 201 into the first storage cavity 101, the gas in the first storage cavity 101 is extruded by the atomized liquid and is discharged to the airflow passage 102 through the position (i.e. the liquid outlet hole 1011) where the atomizing core 12 and the first storage cavity 101 are communicated, so as to realize the exhaust pressure relief of the first storage cavity 101, so that the atomized liquid in the second storage cavity 201 can be continuously guided into the first storage cavity 101; when the gas pressure in the second storage cavity 201 is less than or equal to the first preset threshold, the first one-way valve 41 closes and the first storage cavity 101 and the second storage cavity 201 are isolated, so as to avoid the atomized liquid in the first storage cavity 101 flowing back to the second storage cavity 201 through the first liquid guiding passage 1101 and the second liquid guiding passage 2101, that is, after the atomized liquid stored in the atomizer 1 is consumed by the atomizing core 12, the liquid reservoir 2 can supplement the atomized liquid for the atomizer 1 under the action of the gas charging assembly 32, so as to not only enable the atomizer 1 to be repeatedly used, but also improve the endurance of the electronic atomization device, that is, the electronic atomization device provided in the embodiment has the advantage of long sustainable use time.

[0071] In the embodiment, it can be understood that, since the connection between the first shell 11 and the second shell 21 is detachable, after the atomized liquid in the atomizer 1 and the liquid reservoir 2 is used up, the liquid reservoir 2 is only needed to be detached from the atomizer 1, and then a new liquid reservoir 2 preloaded with atomized liquid is combined with the original atomizer 1 to form an integrated whole, so that the atomized liquid can be continuously supplemented for the original atomizer 1.

[0072] It should be noted here that the specific opening threshold of the first one-way valve 41 can be flexibly set according to actual use needs, as long as the first one-way valve 41 can meet the use requirement of "opening during the process of charging gas into the second storage cavity 201, and closing after the supplement of the atomized liquid is completed", and the embodiment does not make specific limitation on this.

[0073] Further, please refer to Figure 3In some optional embodiments of the present application, the volume of the second storage cavity 201 can be set to be 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 set to 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 supply the atomizer 1 with atomized liquid for multiple times (at least 3 times), and the volume of the liquid reservoir 2 is not set to be 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.

[0074] Further, please refer to Figure 4 and Figures 7-8 In some optional embodiments of the present application, the circumferential part of the first shell 11 corresponding to the first storage cavity 101 is made of transparent material. Specifically, any circumferential side wall of the first shell 11 except the first side wall 111 can be made of transparent material such as glass or acrylic. In this way, the user can observe the content of the atomized liquid in the first storage cavity 101 at any time, so as to intuitively know whether the atomized liquid in the first storage cavity 101 has been consumed or not and whether the first storage cavity 101 has been filled with atomized liquid during the process of supplying the atomizer 1 with atomized liquid by the liquid reservoir 2.

[0075] Similarly, please refer to Figure 3 and Figures 9-10 In some optional embodiments of the present application, the circumferential part of the second shell 21 corresponding to the second storage cavity 201 is made of transparent material. Specifically, any circumferential side wall of the second shell 21 except the second side wall 211 can be made of transparent material such as glass or acrylic. In this way, the user can observe the content of the atomized liquid in the second storage cavity 201 at any time, so as to intuitively know whether the atomized liquid in the second storage cavity 201 has been consumed or not.

[0076] Further, please refer to Figure 3 and Figures 5-6In some optional embodiments of this application, the second housing 21 further has a third sidewall 216 located differently from the second sidewall 211. The third sidewall 216 has an inflation hole 2160 communicating with the second storage cavity 201. The inflation assembly 32 includes a cylinder 321, a plunger 322, and a driving component 323. The cylinder 321 is hollow and forms a cavity 3210. One end of the cylinder 321 along its own axial direction is inserted into the inflation hole 2160, and the cavity 3210 of the cylinder 321 communicates with the second storage cavity 201 of the liquid reservoir 2. The plunger 322 is slidably installed in the cavity 3210. Moreover, the material of the plunger 322 can be silicone, rubber, or silicone rubber. The driving component 323 is connected to the side of the plunger 322 facing away from the inflation hole 2160. The driving component 323 is configured to operably drive the plunger 322 to slide between a first position and a second position.

[0077] like Figure 3 As shown, when the plunger 322 is in the initial first position, the first check valve 41 is closed and the second storage chamber 201 is isolated from the first storage chamber 101.

[0078] like Figure 4 As shown, when it is necessary to replenish the atomizing liquid into the first storage chamber 101 of the atomizer 1, the driving component 323 can be operated in the first way, causing the driving component 323 to drive the plunger 322 to slide from the first position to the second position along the direction close to the air inlet 2160. During the process of the plunger 322 sliding from the first position to the second position, the plunger 322 squeezes the gas in the cavity 3210 of the cylinder 321 out of the cavity 3210 and fills the second storage chamber 201, so that the air pressure in the second storage chamber 201 gradually increases. When the air pressure in the second storage chamber 201 is greater than that of the first one-way valve... When the opening threshold of 41 is reached, the first one-way valve 41 opens, connecting the first storage chamber 101 and the second storage chamber 201. This allows the atomized liquid in the second storage chamber 201 to be introduced into the first storage chamber 101 of the atomizer 1 under air pressure through the second liquid guiding channel 2101 and the first liquid guiding channel 1101 for replenishment. That is, after the atomized liquid stored in the atomizer 1 is consumed by the atomizing core 12, the atomized liquid in the reservoir 2 can be pumped into the first storage chamber 101 of the atomizer 1 for replenishment by operating the drive component 323. After the atomized liquid in the reservoir 2 is replenished into the first storage chamber 101 of the atomizer 1, the drive component 323 can be operated a second time, causing the drive component 323 to drive the plunger 322 to slide from the second position to the initial first position in the direction away from the air filling hole 2160, so that the gas in the cavity 3210 of the cylinder 321 can be pumped into the second storage chamber 201 next time.

[0079] In the embodiment, it should be noted that, in specific implementation, in some optional embodiments, when the second side wall 211 is the left side wall of the second shell 21, the third side wall 216 can be the front side wall, the rear side wall, the right side wall, the bottom wall or the top wall of the second shell 21; in another optional embodiment, when the second side wall 211 is the top wall of the second shell 21, the third side wall 216 can be the bottom wall or the circumferential side wall; in still another optional embodiment, when the second side wall 211 is the bottom wall of the second shell 21, the third side wall 216 can be the top wall or the circumferential side wall. Wherein, when the third side wall 216 is the circumferential side wall or the top wall of the second shell 21, the inflation assembly 32 can be arranged on the first shell 11, at this time, the inflation assembly 32 can be regarded as a component of the liquid reservoir 2, and in this case, the driving component 323 can be in the form of a push rod 3232, one end of which is connected with the plunger 322 and the other end of which is exposed, so that the plunger 322 can be driven to slide back and forth between the first position and the second position by pushing and pulling the push rod 3232.

[0080] Further, in some optional embodiments of the present application, the driving component 323 can be arranged in the power assembly 3 of the atomization main body, in which case, the driving component 323 belongs to the power assembly 3 of the atomization main body, and the barrel 321 can be further designed in a needle cylinder type structure, specifically as follows:

[0081] Please refer to Figure 3 , Figures 5-6 , Figure 10 and Figures 12-16, 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 the right side wall of the first shell 11, and the second side wall 211 is the left side wall of the second shell 21. The third side wall 216 is the bottom wall of the second shell 21. The atomization body further comprises a power assembly 3, the power assembly 3 comprising a third shell 31, a battery 33, a control circuit board 34, and an aeration assembly 32. 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 to the battery 33 and the atomization core 12, respectively. The control circuit board 34 can control the battery 33 to supply power to 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 is connected to the first shell 11 and detachably connected to the second shell 21, respectively. The third shell 31 is provided with a through hole (not labeled in the figure) at a position facing the aeration hole 2160. The cylinder 321 has a first cylinder portion 3211 and a second cylinder portion 3212. The inner diameter and the outer diameter of the first cylinder portion 3211 are both smaller than those of the second cylinder portion 3212. One end of the first cylinder portion 3211 is connected to the end face of one end of the second cylinder portion 3212, and the other end passes through the through hole and is in sealing fit with the aeration hole 2160. The inside of the first cylinder portion 3211 forms a first cavity 32101 which is in communication with the second storage cavity 201. The inside of the second cylinder portion 3212 forms a second cavity 32102. The first cavity 32101 and the second cavity 32102 are in communication to form a cavity 3210. The plunger 322 is slidingly fitted in the second cavity 32102.

[0082] In the present embodiment, it should be noted that in specific implementation, the connection between the first shell 11 and the third shell 31 can be detachable connection (such as magnetic attraction connection, threaded connection, buckle connection, plug-in connection, etc.), or it can be fixed connection (such as integrated connection) which cannot be detached, which can be determined according to actual use needs, and the present embodiment does not make specific limitation thereon. For the detachable connection between the second shell 21 and the third shell 31, it can be magnetic attraction connection, buckle connection or plug-in connection, and the present embodiment also does not make specific limitation thereon. In addition, in specific implementation, the third shell 31 can be an integrated structure, or a split structure assembled by different shell structures, and the present embodiment also does not make specific limitation thereon.

[0083] In the present embodiment, compared with arranging the aeration assembly 32 in the liquid reservoir 2, the advantage of arranging the aeration assembly 32 in the power assembly 3 is that when the atomization liquid in the liquid reservoir 2 is consumed, the aeration assembly 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.

[0084] In the embodiment, considering that the liquid reservoir 2 usually needs to be provided with a pierceable flexible seal 217 (such as a silica gel film or an aluminum foil) at the inflation hole 2160 at the factory to prevent the atomized liquid pre-filled in the second storage cavity 201 from leaking from the inflation hole 2160 when the liquid reservoir 2 is stored and transported alone, based on this, the embodiment sets the inner diameter and the outer diameter of the first barrel portion 3211 to be relatively small, and sets the inner diameter and the outer diameter of the second barrel portion 3212 to be relatively large, so that when the liquid reservoir 2 is combined with the atomization main body to be used as a whole, the first barrel portion 3211 with the relatively small inner and outer diameters can facilitate the piercing of the flexible seal 217, so that the cavity 3210 of the barrel 321 is in communication with the second storage cavity 201 of the liquid reservoir 2; the second barrel portion 3212 with the relatively large inner and outer diameters can provide a larger internal space for storing gas, so as to subsequently fill sufficient gas into the second storage cavity 201 to increase the gas pressure in the second storage cavity 201 when the atomized liquid is replenished. In specific implementation, in order to make the first barrel portion 3211 more easily pierce the flexible seal 217, preferably, the end face of the first barrel portion 3211 away from the second barrel portion 3212 is formed with a sharp corner structure 3213.

[0085] Further, in some optional embodiments of the application, the structure of the driving component 323 can be a hand-pushing structure, and specifically, referring to Figures 3-5 , the driving component 323 includes a hand-pushing piece 3231, a push rod 3232, and a first elastic member 3233 for driving the plunger 322 to reset, the hand-pushing piece 3231 has a bar portion 32311 and a hand-pushing portion 32312 arranged at an included angle (which can be a right angle), the hand-pushing portion 32312 is slidingly connected to the circumferential side wall of the third housing 31 outwardly along the height direction of the third housing 31, one end of the push rod 3232 is fixedly connected to the side of the plunger 322 away from the first barrel portion 3211, the other end of the push rod 3232 is arranged to extend away from the plunger 322 and is connected to the end of the bar portion 32311 away from the hand-pushing portion 32312, one end of the first elastic member 3233 is in abutment with the plunger 322, and the other end is in abutment with the cavity wall of the second cavity 32102.

[0086] In 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 atomization core 12, referring to Figure 4The whole electronic atomization device can be inverted first, and then the pushing part 32312 of the pushing piece 3231 is pushed in the direction close to the second shell 21 by the finger (equivalent to the first operation mentioned in the foregoing embodiment). During the pushing of the pushing part 32312, the rod part 32311 of the pushing piece 3231 drives the push rod 3232 to slide in the direction close to the first cylinder part 3211 together with the plunger 322. During the sliding of the plunger 322 in the direction close to the first cylinder part 3211, the first elastic piece 3233 is gradually compressed, and at the same time, the plunger 322 gradually pressurizes the gas in the second cavity 32102 and the first cavity 32101 into the second storage cavity 201, so that the gas pressure in the second storage cavity 201 gradually increases. When the gas pressure in the second storage cavity 201 is greater than the opening threshold of the first one-way valve 41, the first one-way valve 41 is opened and the first storage cavity 101 and the second storage cavity 201 are communicated, so that the atomized liquid in the second storage cavity 201 can be guided into the first storage cavity 101 of the atomizer 1 in sequence through the second liquid guiding channel 2101 and the first liquid guiding channel 1101 under the action of gas pressure and gravity. During the guiding of the atomized liquid in the second storage cavity 201 into the first storage cavity 101, the gas in the first storage cavity 101 is extruded by the atomized liquid and is discharged to the airflow channel 102 in sequence through the liquid outlet hole 1011 and the installation gap between the outer wall of the atomizing core 12 and the inner wall of the airflow channel 102, so as to realize the exhaust pressure relief of the first storage cavity 101, so that the atomized liquid in the second storage cavity 201 can be continuously guided into the first storage cavity 101. When the gas pressure in the second storage cavity 201 is less than or equal to the opening threshold of the first one-way valve 41, the first one-way valve 41 is closed to isolate the first storage cavity 101 from the second storage cavity 201, so as to avoid the backflow of the atomized liquid in the first storage cavity 101 to the second storage cavity 201 through the first liquid guiding channel 1101 and the second liquid guiding channel 2101. After the supplement of the atomized liquid is completed, the finger is released (equivalent to the second operation mentioned in the foregoing embodiment), so as to remove the force applied to the pushing part 32312. During this process, under the action of the elastic restoring force of the first elastic piece 3233, the plunger 322 is reset to the initial first position and drives the push rod 3232 and the pushing piece 3231 to be reset to the initial position synchronously, so as to pressurize the gas in the cavity 3210 of the cylinder 321 into the second storage cavity 201 next time.

[0087] In the present embodiment, it needs to be explained that, in some optional embodiments, the first elastic member 3233 can also be cancelled, in which case, after the atomized liquid in the second storage cavity 201 is supplemented into the first storage cavity 101, the finger needs to push the hand pushing part 32312 to reset to the initial position in order to reset the plunger 322 from the second position to the first position, that is, if the first elastic member 3233 is cancelled, the user needs to separately reset the plunger 322. In addition, in some optional embodiments, in order to make the atomized liquid in the second storage cavity 201 more easily introduced into the first storage cavity 101 for supplementation, as shown in Figure 3 , along the height direction of the first shell 11 (i.e. Figure 3 , the up and down direction in ), the first liquid guide channel 1101 can be arranged as close to the suction nozzle 13 as possible and the second liquid guide channel 2101 can be arranged as close to the top wall of the second storage cavity 201 as possible.

[0088] Further, please continue to refer to Figures 3-5 , in some optional embodiments of the present application, the driving part 323 further includes a guide cylinder 3234 fixed in the third shell 31, the guide cylinder 3234 is arranged to extend along the height direction of the third shell 31, the end of the push rod 3232 away from the plunger 322 is inserted into the guide cylinder 3234, the side wall of the push rod 3232 is provided with a sliding block part 32321, the inner wall of the guide cylinder 3234 is provided with a guide groove 32340 arranged to extend along the height direction of the guide cylinder 3234, the sliding block part 32321 and the guide groove 32340 are in sliding cooperation, the side wall of the guide cylinder 3234 is provided with a first slit 32341 and a second slit 32342 arranged oppositely, the first slit 32341 and the second slit 32342 are arranged to extend along the axial direction of the guide cylinder 3234, and the end of the rod part 32311 away from the hand pushing part 32312 is arranged to pass through the first slit 32341, the push rod 3232 and the second slit 32342 in sequence. In this way, the guide groove 32340 of the guide cylinder 3234 can guide the push rod 3232 to slide up and down along the height direction of the third shell 31, so that the user can more stably drive the plunger 322 to slide between the first position and the second position through the hand pushing part 3231, that is, it is beneficial to reduce the risk of jamming of the plunger 322 during sliding.

[0089] Further, please continue to refer to Figures 3-5In some optional embodiments of the present application, the driving component 323 further comprises a second elastic member 3235 extending along the height direction of the third housing 31, the second elastic member 3235 being a spring, one end of the second elastic member 3235 being sleeved on the end of the push rod 3232 away from the plunger 322 and abutting against the push rod 3232, and the other end of the second elastic member 3235 abutting against the inner wall of the third housing 31. In this way, during the up-and-down sliding of the push rod 3232 along the height direction of the third housing 31, the second elastic member 3235 can limit the lower end of the push rod 3232 from shaking in a direction perpendicular to the axial direction of the push rod 3232, so that the user can more stably drive the plunger 322 to slide between the first position and the second position by the hand pushing member 3231, that is, it is beneficial to further reduce the risk of the plunger 322 from being stuck during the sliding.

[0090] Further, in some other optional embodiments of the present application, the driving component 323 can also be in an electrically driven structure, specifically, please refer to Figure 6 , the power supply assembly 3 further comprises a control switch 35 electrically connected with the control circuit board 34, the control switch 35 being at least partially exposed out of the third housing 31; the driving component 323 comprises a linear motor 3236 and a push rod 3232, the linear motor 3236 being installed in the third housing 31 and electrically connected with the control circuit board 34, one end of the push rod 3232 being fixedly connected with the side of the plunger 322 away from the first barrel portion 3211, and the other end of the push rod 3232 extending away from the plunger 322 and being fixedly connected with the output shaft of the linear motor 3236.

[0091] 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 for example to illustrate. Specifically, after the atomized liquid in the first storage cavity 101 of the atomizer 1 is consumed by the atomizing 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 drawings) to drive the plunger 322 to slide along the height direction of the third housing 31. Figure 6When the control switch 35 is slid in the first direction (away from the suction nozzle 13) (corresponding to the first operation mentioned in the foregoing embodiments), the control circuit board 34 controls the output shaft of the linear motor 32 36 to perform an extension movement in the direction close to the cylinder 32 1, thereby pushing the push rod 32 32 and the plunger 32 2 to slide in the direction close to the first cylinder part 32 1 1. During the sliding of the plunger 32 2 in the direction close to the first cylinder part 32 1 1, the plunger 32 2 gradually pushes the gas in the second cavity 32 1 02 and the first cavity 32 1 01 into the second storage cavity 201, so that the air pressure in the second storage cavity 201 gradually increases. When the air pressure in the second storage cavity 201 is greater than the opening threshold of the first one-way valve 41, the first one-way valve 41 opens and connects the first storage cavity 101 and the second storage cavity 201, so that the atomized liquid in the second storage cavity 201 can be guided into the first storage cavity 101 of the atomizer 1 through the second liquid guiding channel 21 01 and the first liquid guiding channel 1 101 under the action of air pressure and gravity. After the supplement is completed, the control switch 35 is slid in the second direction (opposite to the first direction) (corresponding to the second operation mentioned in the foregoing embodiments), so that the control circuit board 34 controls the output shaft of the linear motor 32 36 to perform a retraction movement in the direction away from the cylinder 32 1, thereby pulling the push rod 32 32 and the plunger 32 2 to slide in the direction away from the first cylinder part 32 1 1 until the plunger 32 2 returns to the initial first position, so as to press the gas in the cavity 32 1 0 of the cylinder 32 1 into the second storage cavity 201 next time.

[0092] In this embodiment, compared with the technical solution of the structure of the driving part 323 as a hand-push type in the embodiments shown in Figure 3 and Figure 5 In this embodiment, the structure of the driving part 323 is designed as an electric type, which has the advantage that the user's finger does not need to keep pressing the pushing part 32 312 for a long time during the supplement of the atomized liquid in the second storage cavity 201 into the first storage cavity 101, thereby saving the user's strength and improving the user's experience.

[0093] Further, please refer to Figures 3-4 and Figure 6In some optional embodiments of the present application, the first side wall 111 is further provided with a first backflow channel 1102 in communication with the first storage cavity 101, and the first backflow channel 1102 and the first liquid guide channel 1101 are arranged to be spaced apart from each other along the height direction of the first shell 11; the second side wall 211 is further provided with a second backflow channel 2102 in communication with the second storage cavity 201, and the second backflow channel 2102 and the second liquid guide channel 2101 are arranged to be spaced apart from each other along the height direction of the second shell 21, and the second backflow channel 2102 is arranged to be closer to the inflation hole 2160 than the second liquid guide channel 2101; the first backflow channel 1102 and the second backflow channel 2102 are in communication, and a second one-way valve 42 is arranged on the path of the first backflow channel 1102 and the second backflow channel 2102 in communication, and the second one-way valve 42 is arranged to be opened when the air pressure in the first storage cavity 101 is greater than a second preset threshold value (i.e., the opening threshold value of the second one-way valve 42).

[0094] In the present embodiment, based on the above structural design, in the process of guiding the atomized liquid in the second storage into the first storage cavity 101, the second one-way valve 42 can play a role of auxiliary exhaust pressure relief for the first storage cavity 101 (equivalent to a "fuse" role), thereby reducing the risk of leakage of the atomized liquid from the liquid outlet hole 1011. Specifically, please refer to Figure 4In the process of inverting the entire electronic atomization device and guiding the atomized liquid in the second storage cavity 201 into the first storage cavity 101, the gas in the first storage cavity 101 will be pressed by the atomized liquid, and these gases can not be completely and smoothly discharged into the airflow channel 102 through the liquid outlet hole 1011 and the installation gap between the outer wall of the atomization core 12 and the inner wall of the airflow channel 102. When the gas in the first storage cavity 101 cannot be smoothly discharged into the airflow channel 102, in the process of driving the plunger 322 to press the gas in the barrel 321 into the second storage cavity 201, the air pressure in the first storage cavity 101 will increase and cause the atomized liquid in the first storage cavity 101 to be squeezed out of the liquid outlet hole 1011 into the airflow channel 102 due to excessive air pressure, thereby causing a liquid leakage phenomenon. Based on this, in order to reduce the risk of atomized liquid leakage from the liquid outlet hole 1011, the first return channel 1102 and the second return channel 2102 are added, and the second one-way valve 42 is added to the communication path of the first return channel 1102 and the second return channel 2102. In this way, when the air pressure in the first storage cavity 101 is too high due to the gas in the first storage cavity 101 being unable to be smoothly discharged into the airflow channel 102 through the liquid outlet hole 1011, the second one-way valve 42 will be opened, allowing the gas in the first storage cavity 101 to be guided into the second storage cavity 201 through the first return channel 1102 and the second return channel 2102 (here, it can be understood that if the liquid level of the atomized liquid in the first storage cavity 101 is higher than the port of the first return channel 1102 at this time, part of the atomized liquid in the first storage cavity 101 will also flow back to the second storage cavity 201), thereby achieving the pressure relief of the first storage cavity 101 and reducing the risk of atomized liquid leakage from the liquid outlet hole 1011. When the gas in the first storage cavity 101 is guided into the second storage cavity 201 through the first return channel 1102 and the second return channel 2102, the air pressure in the second storage cavity 201 will increase, thereby causing the atomized liquid in the second storage cavity 201 to continue to be guided into the first storage cavity 101 through the second liquid guiding channel 2101 and the first liquid guiding channel 1101, until the air pressure in the first storage cavity 101 is less than or equal to the opening threshold of the second one-way valve 42 and the air pressure in the second storage cavity 201 is less than or equal to the opening threshold of the first one-way valve 41, the first one-way valve 41 and the second one-way valve 42 are automatically closed, thereby completing a liquid supplementing process.

[0095] In this embodiment, it should be noted that in order to guide as much atomized liquid as possible in the second storage cavity 201 into the first storage cavity 101, Figure 3 and Figure 6As shown, along the height direction of the first housing 11, the first backflow passage 1102 can be arranged as close to the bottom wall of the first storage cavity 101 as possible, and the second backflow passage 2102 can be arranged as close to the bottom wall of the second storage cavity 201 as possible.

[0096] It should be noted here that, in specific implementation, the first one-way valve 41 can be arranged in the first liquid guide passage 1101 or in the second liquid guide passage 2101, which can be determined according to actual use requirements, and the present embodiment does not make specific limitations thereon. Similarly, the second one-way valve 42 can be arranged in the first backflow passage 1102 or in the second backflow passage 2102, which can be determined according to actual use requirements, and the present embodiment does not make specific limitations thereon. Exemplarily, as shown in Figure 3 、 Figure 6 and Figure 10 , the first one-way valve 41 is arranged in the second liquid guide passage 2101, and the second one-way valve 42 is arranged in the second backflow passage 2102. It can be understood here that, generally speaking, since the liquid reservoir 2 is a consumable, that is, when the atomized liquid in the second storage cavity is consumed, the entire liquid reservoir 2 will be discarded, therefore, in order to reduce the manufacturing cost of the liquid reservoir 2, in specific implementation, the first one-way valve 41 and the second one-way valve 42 can be arranged in the atomizer 1, so that, compared with arranging the first one-way valve 41 and the second one-way valve 42 in the liquid reservoir 2, the first one-way valve 41 and the second one-way valve 42 can be avoided from being wasted along with the discarding of the liquid reservoir 2. In addition, the specific opening threshold of the second one-way valve 42 can be flexibly set according to actual use needs, as long as the second one-way valve 42 can meet the use requirement of “opening when the air pressure in the first storage cavity 101 is too large, and closing after the supplement of the atomized liquid is completed”, and the present embodiment does not make specific limitations thereon.

[0097] Further, please refer to Figure 3 、 Figures 5-6 and Figures 9-10 , in some optional embodiments of the present application, the first sealing ring 23 is arranged between the first side wall 111 and the second side wall 211, and the first sealing ring 23 is arranged around at least one of the first liquid guide passage 1101 and the second liquid guide passage 2101. Exemplarily, as shown in Figure 3 and Figures 9-10 , the first sealing ring 23 is sleeved on the outer wall of the part of the second housing 21 having the second liquid guide passage 2101, and the first sealing ring 23 is in contact with the first side wall 111. In this way, in the process of guiding the atomized liquid in the second storage cavity 201 into the first storage cavity 101, the atomized liquid can be prevented from leaking to the outside through the installation gap between the first liquid guide passage 1101 and the second liquid guide passage 2101.

[0098] Similarly, please refer toFigure 3 , Figure 6 as well as Figures 9-10 In some optional embodiments of this application, in order to prevent the atomized liquid in the second storage cavity 201 from leaking to the outside through the installation gap between the first return channel 1102 and the second return channel 2102 during the process of introducing the atomized liquid in the second storage cavity 201 into the first storage cavity 101, a second sealing ring 24 can be sandwiched between the first side wall 111 and the second side wall 211, and the second sealing ring 24 is arranged around at least one of the first return channel 1102 and the second return channel 2102.

[0099] Further, please refer to Figure 5 In some alternative embodiments of this application, an exhaust channel 1103 is provided on the bottom wall of the first storage chamber 101. The exhaust channel 1103 is connected to the first storage chamber 101 and the airflow channel 102 respectively. The atomizer 1 also includes a second one-way valve 42 sealed in the exhaust channel 1103. The second one-way valve 42 is set to open when the air pressure in the first storage chamber 101 is greater than a second preset threshold (i.e., the opening threshold of the second one-way valve 42). With this configuration, when the entire electronic atomizing device is inverted and the atomizing liquid in the second storage chamber 201 is introduced into the first storage chamber 101, if the gas in the first storage chamber 101 cannot smoothly pass through the liquid outlet 1011, the installation gap between the outer wall of the atomizing core 12 and the inner wall of the airflow channel 102 to escape into the airflow channel 102, resulting in excessive gas pressure in the first storage chamber 101, the second one-way valve 42 will open, allowing the gas in the first storage chamber 101 to escape into the second storage chamber 201 through the exhaust channel 1103. That is, the second one-way valve 42 can assist in venting and depressurizing the first storage chamber 101, thereby reducing the risk of leakage of the atomizing liquid from the liquid outlet 1011 in the first storage chamber 101. Moreover, compared to... Figure 3 and Figure 6 In the illustrated embodiment, the second one-way valve 42 is positioned on the communication path between the first return channel 1102 and the second return channel 2102. This embodiment employs a technical solution where an exhaust channel 1103 connected to the airflow channel 102 is provided on the bottom wall of the first storage cavity 101, and the second one-way valve 42 is positioned in the exhaust channel 1103. This solution can prevent the atomized liquid in the second storage cavity 201 from flowing back into the second storage cavity 201 during the process of introducing the atomized liquid from the second storage cavity 201 into the first storage cavity 101, thereby making it easier for the atomized liquid to fill the first storage cavity 101.

[0100] Furthermore, please continue to refer to Figure 5In some optional embodiments of the present application, the power supply assembly 3 further comprises a third one-way valve 38, which is at least partially arranged in the first cavity 32101, and is arranged to be opened when the air pressure in the second cavity 32102 is greater than a third preset threshold. In this way, it can not only ensure that the gas in the barrel 321 can be normally pressed into the second storage cavity 201 by the plunger 322, but also prevent the atomized liquid in the second storage from flowing into the cavity 3210 of the barrel 321 to corrode the first elastic member 3233 when the plunger 322 is in the initial first position and the electronic atomization device is in the upright placement state (i.e. not inverted). It should be noted that the specific opening threshold of the third one-way valve 38 can be flexibly set according to actual use needs, as long as the third one-way valve 38 can meet the use requirement of "being opened during driving the plunger 322 to charge the second storage cavity 201, and being closed after the plunger 322 is reset to the initial first position", which is not limited in the present embodiment.

[0101] 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 both be detachable snap connections, specifically:

[0102] Please refer to Figure 3 and Figures 7-18The first end of the third shell 31 is internally provided with a containing cavity 310, and the first shell 11 and the second shell 21 are at least partially accommodated in the containing cavity 310. A first clamping hole 3101 is arranged on the cavity wall of the containing cavity 310 away from the first side wall 111, and a second clamping hole 3102 is arranged on the cavity wall of the containing cavity 310 away from the second side wall 211. A first recess 114 and a first elastic buckle 113 made of plastic are arranged on the side outer wall of the first shell 11 away from the first side wall 111. One end of the first elastic buckle 113 is integrally connected with the outer wall of the first shell 11, and the other end extends in the direction close to the bottom wall of the containing cavity 310 and is formed with a first clamping portion 1131 arranged away from the first recess 114. The first clamping portion 1131 is clamped 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 containing cavity 310 away from the first side wall 111, and correspondingly, the first clamping portion 1131 has a second inclined surface arranged facing the first inclined surface). There is a gap between the side surface of the first elastic buckle 113 away from the first clamping hole 3101 and the groove wall surface of the first recess 114. The second shell 21 is provided with a second recess 214 and a second elastic buckle 213 made of plastic on the side outer wall away from the second side wall 211. One end of the second elastic buckle 213 is integrally connected with the outer wall of the second shell 21, and the other end extends in the direction close to the bottom wall of the containing cavity 310 and is formed with a second clamping portion 2131 arranged away from the second recess 214. The second clamping portion 2131 is clamped in the second clamping hole 3102 and can form sliding contact with the hole wall of the second clamping hole 3102 (for example, the top wall surface of the second clamping hole 3102 is a third inclined surface arranged at an obtuse angle with the cavity wall of the containing cavity 310 away from the second side wall 211, and correspondingly, the second clamping portion 2131 has a fourth inclined surface arranged facing the third inclined surface). There is a gap between the side surface of the second elastic buckle 213 away from the second clamping hole 3102 and the groove wall surface of the second recess 214.

[0103] In the present embodiment, based on the above structural design, when the three modules of the atomizer 1, the liquid reservoir 2 and the power supply assembly 3 are combined into a complete electronic atomization device, the first side wall 111 of the atomizer 1 can be first combined with the second side wall 211 of the liquid reservoir 2 to form a combined atomizer, then the through hole part of the second shell 21 is made to correspond to the through hole on the bottom wall of the accommodating cavity 310, and then the bottom of the entire combined atomizer is inserted into the accommodating cavity 310 of the third shell 31. 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 part 1131 is directly opposite the first card hole 3101 and the second buckle part 2131 is directly opposite the second card hole 3102, the lower end of the first elastic buckle 113 returns to its original state and the first buckle part 1131 is buckled to the first card hole 3101, and the lower end of the second elastic buckle 213 returns to its original state and the second buckle part 2131 is buckled to the second card 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 from each other. 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 three modules of the atomizer 1, the new liquid reservoir 2 and the power supply assembly 3 into a new electronic atomization device.

[0104] Further, please refer to Figure 1 , Figure 11 and Figure 18 , in some optional embodiments of the present application, the circumferential side wall of the first shell 11 except the first side wall 111 is provided with a first flange part 115 extending along the circumference of the first shell 11, the circumferential side wall of the second shell 21 except the second side wall 211 is provided with a second flange part 215 extending along the circumference of the second shell 21, the first flange part 115 and the second flange part 215 are opposite to each other to form a ring-shaped flange 5, and the ring-shaped flange 5 covers one end face of the third shell 31 provided with the accommodating cavity 310. In this way, the ring-shaped flange 5 can shield the installation gap between the first shell 11 and the third shell 31 and between the second shell 21 and the third shell 31, thereby facilitating the improvement of the appearance aesthetics of the electronic atomization device.

[0105] Further, in order to facilitate the electrical connection between the atomization core 12 and the control circuit board 34 after the bottom of the atomizer 1 is inserted into the accommodating cavity 310 of the third shell 31, please refer to Figure 3 , Figures 7-8、 Figure 12 And Figures 14-15 In some optional embodiments of the present application, the atomizer 1 further comprises a first electrode assembly 15 electrically connected with the atomizing core 12, the first electrode assembly 15 is arranged on the bottom wall of the first shell 11, the power supply assembly 3 further comprises a second electrode assembly 37 electrically connected with the control circuit board 34, the second electrode assembly 37 is arranged on the bottom wall of the accommodating cavity 310, and the first electrode assembly 15 and the second electrode assembly 37 are in electrical contact. Wherein, in specific implementation, the structure form of the first electrode assembly 15 can be a conductive nail, and the structure form of the second electrode assembly 37 can be a conductive needle.

[0106] Further, in order to facilitate the formation of suction airflow in the airflow passage 102 when the user bites the suction nozzle 13 to perform suction after inserting the bottom of the atomizer 1 into the accommodating cavity 310 of the third shell 31, please refer to Figure 3 、 Figure 7 And Figures 13-15 In some optional embodiments of the present application, the bottom wall of the first shell 11 is provided with a first air inlet hole 116 communicating with the airflow passage 102, the outer side wall of the third shell 31 is provided with a second air inlet hole 311, the bottom wall of the accommodating cavity 310 is provided with an air hole 3103 communicating with the second air inlet hole 311, and the air hole 3103 and the first air inlet hole 116 correspondingly communicate.

[0108] Correspondingly, please refer to Figure 1 、 Figure 3 、 Figures 5-6 And Figures 9-12 The present application also provides a liquid storage device, which is used in combination with the atomizing main body (such as shown in Figures 2-3 And Figures 5-6 ) containing the power supply assembly 3 in the foregoing electronic atomizing device, the liquid storage device comprises a second shell 21 and a first one-way valve 41, wherein:

[0109] The second housing 21 has a second storage cavity 201 for storing atomizing liquid. The second housing 21 has a second sidewall 211 along its circumference. The second sidewall 211 has a second liquid guiding channel 2101 through which the atomizing liquid can pass. The bottom wall of the second housing 21 has an air inlet 2160. A flexible seal 217 that can be punctured by a foreign object is provided at the air inlet 2160. For example, the flexible seal 217 includes a film portion 2172 and a hollow sleeve portion 2171.

The sleeve portion 2171 is assembled at the air inlet 2160. The film portion 2172 is sealed and connected (such as integrally connected) to the inner wall of the sleeve portion 2171.

[0110] The first one-way valve 41 is at least partially disposed within the second liquid guiding channel 2101. Considering that in some specific application scenarios, the atomizer 1 usually needs to be provided with a puncturable seal 14 (such as a silicone film or aluminum foil) in the first liquid guiding channel 1101 at the time of manufacture to prevent the atomized liquid pre-filled in the first storage chamber 101 from leaking from the first liquid guiding channel 1101 when the atomizer 1 is stored and transported separately, in specific implementation, one end of the first one-way valve 41 can be exposed from the second liquid guiding channel 2101, and the rest of the first one-way valve 41 is disposed within the second liquid guiding channel 2101. With this configuration, when the first side wall 111 of the atomizer 1 is joined with the second side wall 211 of the liquid reservoir 2 to form a combined atomizer, one end of the first one-way valve 41 can pierce the seal so that when the first one-way valve 41 is opened, the first storage chamber 101 can be connected to the second storage chamber 201.

[0111] like Figures 3-6 As shown, when the liquid storage device is combined with the atomizing body containing the power supply component 3, the second sidewall 211 is detachably connected to the first sidewall 111, the second liquid guiding channel 2101 is connected to the first liquid guiding channel 1101, and the end of the first cylinder 3211 away from the second cylinder 3212 pierces the film portion 2172 of the flexible seal 217 and forms a sealing fit with the air filling hole 2160 through the sleeve portion 2171 (that is, the outer peripheral wall of the first cylinder 3211 is in close contact with the inner wall of the sleeve portion 2171); during the process of the plunger 322 sliding from the first position to the second position in the direction close to the air filling hole 2160, the air in the second cavity 32102 of the second cylinder 321 is forced into the second storage cavity 201 by the plunger 322 to open the first one-way valve 41 and make the first storage cavity 101 and the second storage cavity 201 connected.

[0112] In the embodiment, when the atomized liquid stored in the atomizer 1 is consumed by the atomizing core 12, the liquid storage device provided in the embodiment can supplement the atomized liquid for the atomizer 1 under the action of the gas charging assembly 32, so that the atomizer 1 can be repeatedly used, and the endurance of the electronic atomization device can be improved. It should be noted that other contents of the liquid storage device provided in the embodiment can refer to the related contents of the liquid storage device 2 in the above electronic atomization device embodiments, and will not be described here.

[0114] In the embodiment, the power supply device provided in the embodiment can not only provide electric energy for the atomizing core 12 in the atomizer 1, but also can be operable to charge gas into the second storage cavity 201 of the liquid storage device 2, so that the liquid storage device 2 can supplement 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.
