Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to a liquid storage device, a power supply assembly, and a vapor generation device. Background Technology

[0002] A vapor generator is an electronic device that can vaporize stored e-liquids, medicines, or other atomizing liquids into vapor through electric heating. A vapor generator typically includes an atomizer and a power supply unit. 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 unit is used to supply power to the atomizing core.

[0003] 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. Summary of the Invention

[0004] The main objective of this application is to provide a liquid storage device, a power supply component, and a vapor generation device, aiming to solve the technical problem that atomizers cannot be reused in related technologies.

[0005] To achieve the above objectives, in a first aspect, this application provides a vapor-generating device, which includes an atomizing body and a liquid reservoir, wherein:

[0006] The atomizing body includes an atomizer, which includes a first housing, a mouthpiece, and an atomizing core. The first housing has an airflow channel and a first storage chamber for storing atomized liquid. The mouthpiece is connected to the top of the first housing and communicates with the airflow channel. The atomizing core is installed on the airflow path of the airflow channel and communicates with the first storage chamber. The first housing has a first sidewall with a first liquid guiding portion for the atomized liquid to pass through, and the first liquid guiding portion communicates with the first storage chamber.

[0007] A liquid reservoir includes a second housing and a valve. The second housing has a second sidewall and a second liquid guide portion through which atomized liquid can pass. The second sidewall is detachably connected to a first sidewall, and the second liquid guide portion is in contact with the first liquid guide portion. The second housing has an installation cavity for mounting the valve and a second storage cavity for storing the atomized liquid. The valve is movably connected to the installation cavity and is operable to move relative to the second housing between a first position and a second position. When the valve moves relative to the second housing to the first position, the second liquid guide portion is isolated from the second storage cavity, thereby isolating the first storage cavity from the second storage cavity. When the valve moves relative to the second housing to the second position, the second liquid guide portion is connected to the second storage cavity, thereby connecting the first storage cavity to the second storage cavity.

[0008] In some embodiments, the first sidewall is the circumferential sidewall of the first housing, the second sidewall is the circumferential sidewall of the second housing, the second housing further includes a third sidewall located differently from the second sidewall, the third sidewall being provided with a through hole, the vapor generating device further includes a driving component disposed corresponding to the through hole, the through hole being connected to the mounting cavity and used for at least a portion of the driving component to extend into, the driving component being configured to operably cause the valve to move between the first position and the second position.

[0009] In some embodiments, the second housing has a partition portion located between the mounting cavity and the second storage cavity, the partition portion having a liquid passage hole communicating with the second storage cavity, and the valve including a slide plate slidably connected to the mounting cavity, the slide plate having a connecting hole; wherein, when the slide plate is in the first position, the slide plate simultaneously covers the liquid outlet end of the liquid passage hole and the liquid inlet end of the second liquid guide portion, thereby isolating the second liquid guide portion from the second storage cavity; when the slide plate is driven by the driving component to slide to the second position, the connecting hole communicates with the liquid outlet end of the liquid passage hole and the liquid inlet end of the second liquid guide portion, respectively, thereby connecting the second liquid guide portion to the second storage cavity.

[0010] In some embodiments, the reservoir further includes a first elastic member located within the mounting cavity, one end of the first elastic member abutting against the cavity wall of the mounting cavity and the other end abutting against the sliding plate, the first elastic member being configured to drive the sliding plate back to the first position when the driving member removes the force applied to the sliding plate.

[0011] In some embodiments, the atomizing body further includes a power supply assembly, which includes a third housing, a battery, a control circuit board, and the driving component. The battery and the control circuit board are both installed within the third housing. The control circuit board is electrically connected to the battery and the atomizing core, respectively. One end of the third housing along its height direction is connected to the first housing and detachably connected to the second housing. The third sidewall is the bottom wall of the second housing, and a through hole is provided on the portion of the third housing facing the third sidewall. The driving component includes a first push member, a push rod, a lever rotatably installed within the third housing, and a second elastic member for resetting the push rod. The first push member has a push portion and a rod portion connected as one unit. The push portion extends along the height direction of the third housing. The push rod is slidably connected to the outer wall of the third housing. One end of the rod facing away from the pusher abuts against one end of the lever. The push rod is slidably installed inside the third housing along the height direction of the third housing. One end of the push rod abuts against the end of the lever facing away from the rod, and the other end is set corresponding to the through hole. The through hole is connected to the through hole and is used for the push rod facing away from the lever to pass through. One end of the second elastic member is fixed relative to the third housing, and the other end is fixed relative to the push rod. When the pusher is subjected to an external force to drive the lever to rotate, the end of the push rod facing away from the lever abuts against the slide plate after passing through the through hole and extending into the through hole, thereby driving the slide plate to slide from the first position to the second position.

[0012] In some embodiments, the atomizing body further includes a power supply assembly, which includes a third housing, a battery, a control circuit board, a control switch, and the driving component. One end of the third housing along its height direction is connected to the first housing and detachably connected to the second housing. The third sidewall is the bottom wall of the second housing. A through hole is provided on the portion of the third housing facing the third sidewall. The battery and the control circuit board are both installed inside the third housing.

The driving component includes a linear motor and a push rod. The linear motor is installed inside the third housing and electrically connected to the control circuit board. The push rod is slidably installed inside the third housing along its height direction. One end of the push rod is fixedly connected to the output shaft of the linear motor, and the other end is provided corresponding to the through hole. The through hole communicates with the through-hole portion and is used for the end of the push rod away from the linear motor to pass through.

[0013] In some embodiments, a receiving cavity is provided at one end of the third housing, and at least a portion of the first housing and at least a portion of the second housing are received in the receiving cavity. The atomizer further includes a first electrode assembly electrically connected to the atomizing core, the first electrode assembly being disposed on the bottom wall of the first housing.

[0015] In some embodiments, the first elastic element is a spring, and a positioning post is protruding from the side surface of the slide plate facing away from the through hole, the positioning post extending into one end of the first elastic element.

[0016] In some embodiments, the first sidewall is provided with at least one fastener, and the second housing has a frame portion surrounding the second sidewall. The inner wall of the frame portion is provided with at least one slot, and each fastener is engaged with each slot in a one-to-one correspondence.

[0017] In some embodiments, the first liquid guiding portion includes a liquid guiding hole, and the second liquid guiding portion includes a hollow liquid guiding protrusion, the liquid guiding protrusion being inserted into the liquid guiding hole and sealingly communicating with the first storage cavity.

[0018] In some embodiments, a first sealing member is fixed on the side of the slide plate facing the liquid passage hole, which surrounds the liquid inlet end of the connecting hole, and a second sealing member is fixed on the side of the slide plate facing the second liquid guide portion, which surrounds the liquid outlet end of the connecting hole. Both the first sealing member and the second sealing member are in contact with the cavity wall of the mounting cavity.

[0019] Secondly, this application also provides a liquid storage device for detachably combining with the atomizing body in the vapor generating device described in any of the above embodiments, wherein the liquid storage device is the liquid reservoir in the vapor generating device described in any of the above embodiments.

[0020] Thirdly, this application also provides a power supply component for detachable combination with a combined atomizer, the combined atomizer including the aforementioned liquid storage device and the atomizer in the vapor generating device described in any of the above embodiments, and the power supply component being the power supply component in the vapor generating device described in any of the above embodiments.

[0021] Compared with the prior art, this application has at least the following beneficial effects:

[0022] In the technical solution of this application, a first liquid guiding part communicating with the first storage cavity is provided on the first side wall of the atomizer, and a liquid reservoir capable of storing atomized liquid separately is added. The second side wall of the liquid reservoir is detachably connected to the first side wall of the atomizer and is provided with a second liquid guiding part that is opposite to the first liquid guiding part. Moreover, a valve for opening and closing the second liquid guiding part is provided inside the liquid reservoir. With this configuration, once the atomizing fluid in the first storage chamber of the atomizer is depleted by the atomizing core, the valve of the reservoir can be opened (i.e., the valve is in the second position). This connects the first storage chamber of the atomizer to the second storage chamber of the reservoir via the first and second liquid guiding sections. The atomizing fluid in the second storage chamber of the reservoir can then be guided into the first storage chamber of the atomizer through the second and first liquid guiding sections for replenishment. After replenishment, the valve is closed (i.e., the valve is in the first position), isolating the first storage chamber of the atomizer from the second storage chamber of the reservoir. This prevents the atomizing fluid in the first storage chamber from flowing back into the second storage chamber. In other words, the reservoir can replenish the atomizer's atomizing fluid after it has been depleted by the atomizing core, allowing the atomizer to be reused repeatedly and improving the battery life of the vapor generator.

[0062] Please refer to Figure 1-13 , Figure 18-21 as well as Figure 26-27 One embodiment of this application provides a vapor generating device, which includes an atomizing body and a liquid reservoir 2. The atomizing body includes an atomizer 1, wherein:

[0063] The atomizer 1 includes a first housing 11 and an atomizing core 12. The first housing 11 has an airflow channel 102 and a first storage chamber 101 for storing atomized liquid. The first housing 11 has a first sidewall 111, and the first sidewall 111 has a first liquid guiding part 110 for the atomized liquid to pass through. The first liquid guiding part 110 is connected to the first storage chamber 101. The atomizing core 12 is installed in the first housing 11 and is connected to the first storage chamber 101. (Specifically, the cavity wall of the first storage chamber 101 has a liquid outlet hole 1011 corresponding to the atomizing core 12, and the atomizing core 12 is connected to the first storage chamber 101 through the liquid outlet hole 1011.) The atomizing core 12 is located in the airflow path of the airflow channel 102, so that the vapor generated by the atomizing 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 inhale. In addition, for the convenience of the user to inhale, the top of the first housing 11 is connected to a mouthpiece 13 (the mouthpiece 13 can be made of plastic) that communicates with the airflow channel 102. When the user bites the mouthpiece 13 to inhale, a suction airflow can be formed in the airflow channel 102.

[0064] The reservoir 2 includes a second housing 21 and a valve 22. The second housing 21 has a second side wall 211 and a second liquid guiding part 210 for the atomizing liquid to pass through. The second side wall 211 is detachably connected to the first side wall 111 and the second liquid guiding part 210 is connected to the first liquid guiding part 110. The second housing 21 has an installation cavity 202 for installing the valve 22 and a second storage cavity 201 for storing the atomizing liquid. The valve 22 is movably connected to the installation cavity 202 and can be operablely moved between a first position and a second position relative to the second housing 21.

[0065] like Figure 3 As shown, when the valve 22 moves to the first position relative to the second housing 21, the second liquid guiding part 210 is isolated from the second storage chamber 201. At this time, it is equivalent to the second liquid guiding part 210 being closed by the valve 22, thereby isolating the first storage chamber 101 of the atomizer 1 from the second storage chamber 201 of the liquid reservoir 2, so as to prevent the atomized liquid in the first storage chamber 101 from flowing back into the second storage chamber 201.

[0066] like Figure 5 As shown, when the valve 22 moves to the second position relative to the second housing 21, the second liquid guiding part 210 is connected to the second storage chamber 201. At this time, it is equivalent to the second liquid guiding part 210 being opened by the valve 22, so that the first storage chamber 101 of the atomizer 1 can be connected to the second storage chamber 201 of the reservoir 2 through the first liquid guiding part 110 and the second liquid guiding part 210, so as to introduce the atomized liquid in the second storage chamber 201 into the first storage chamber 101 for replenishment.

[0067] In this embodiment, it should 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... Figure 9 and Figure 11 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 the first sidewall 111 and the second sidewall 211 can be planar, curved, formed by connecting planar and curved surfaces, or formed by connecting different planar surfaces, depending on actual usage requirements. This embodiment does not impose specific limitations on the specific structural form of the first sidewall 111 and the second sidewall 211.

[0068] In this embodiment, it should also be noted that, in specific implementation, the detachable connection between the first sidewall 111 and the second sidewall 211 can be a snap-fit ​​connection, a magnetic connection, or a threaded connection, as long as it meets the usage requirements. This embodiment does not impose specific limitations in this regard. For example, as... Figure 9 , Figure 11 and Figure 17 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 is provided with at least one snap-fit ​​member 112, and the second housing 21 has a frame portion 212 surrounding the second sidewall 211. The inner wall of the frame portion 212 is provided with at least one slot 2120, and each snap-fit ​​member 112 is engaged with each slot 2120 in a one-to-one correspondence.

[0069] In this embodiment, it should also be noted that, in specific implementation, the user can operate the valve 22 by pressing, pushing, or rotating, as long as it meets the usage requirements. This embodiment does not impose specific limitations in this regard. It can be understood that when the user operates the valve 22 by pressing or pushing, the valve 22 is slidably connected within the mounting cavity 202 of the second housing 21; when the user operates the valve 22 by rotating, the valve 22 is rotatably connected within the mounting cavity 202 of the second housing 21.

[0070] In this embodiment, it should be further noted that, in specific implementation, the structure of the first liquid guiding part 110 can be a hole-like structure, and the structure of the second liquid guiding part 210 can be a plug-like structure; or, the structure of the first liquid guiding part 110 can be a plug-like structure, and the structure of the second liquid guiding part 210 can be a hole-like structure; or, the structure of both the first liquid guiding part 110 and the second liquid guiding part 210 can be a hole-like structure; or, the structure of both the first liquid guiding part 110 and the second liquid guiding part 210 can be a plug-like structure. As long as the first liquid guiding part 110 and the second liquid guiding part 210 are connected and the valve 22 is in the second position, the first storage cavity 101 and the second storage cavity 201 can be interconnected. This embodiment does not impose specific restrictions on the specific structural forms of the first liquid guiding part 110 and the second liquid guiding part 210. In some specific application scenarios, to make the connection between the first liquid guiding part 110 and the second liquid guiding part 210 more convenient and reliable, and considering that the atomizer 1 usually needs to be provided with a puncturable sealing body 14 (such as a silicone film or aluminum foil) at the first liquid guiding part 110 during the factory to prevent the atomizing liquid pre-filled in the first storage chamber 101 from leaking from the first liquid guiding part 110 when the atomizer 1 is stored and transported separately, therefore, optionally, the structure of the first liquid guiding part 110 is a hole-type structure, and the structure of the second liquid guiding part 210 is a plug-type structure. Specifically, such as... Figure 9-13 and Figure 17 As shown, the first liquid guiding part 110 includes a liquid guiding hole 1101, and a pierceable sealing body 14 is provided at the liquid guiding hole 1101. The second liquid guiding part 210 includes a hollow liquid guiding protrusion 2101. The liquid guiding protrusion 2101 is inserted into the liquid guiding hole 1101 and pierces the sealing body 14 to seal and communicate with the first storage cavity 101. For ease of description, the following related technical content will be described with the example that the structure of the first liquid guiding part 110 is a hole-type structure and the structure of the second liquid guiding part 210 is a plug-type structure. In order to achieve a sealed connection between the liquid guiding protrusion 2101 and the first storage cavity 101, and to prevent the atomized liquid in the first storage cavity 101 from leaking to the outside through the fitting gap between the liquid guiding protrusion 2101 and the liquid guiding hole 1101 after the atomizer 1 and the liquid reservoir 2 are combined into one unit, a sealing ring 27 can be provided between the liquid guiding protrusion 2101 and the liquid guiding hole 1101. For example, the outer wall of the liquid guiding protrusion 2101 is fitted with a sealing ring 27 that contacts the first housing 11.

[0071] 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 valve 22 of the reservoir 2 can be opened (i.e., the valve 22 is placed in the second position), so that the first storage chamber 101 of the atomizer 1 is connected to the second storage chamber 201 of the reservoir 2. Then, the atomizing liquid in the second storage chamber 201 of the reservoir 2 can be introduced into the first storage chamber 101 of the atomizer 1 through the second liquid guide 210 for replenishment. After replenishment, the valve 22 is closed (i.e., the valve 22 is placed in the second position). With valve 22 in the first position, the first storage chamber 101 of the atomizer 1 is isolated from the second storage chamber 201 of the reservoir 2, preventing the atomized liquid in the first storage chamber 101 from flowing back into the second storage chamber 201. This means the reservoir 2 can replenish the atomizer 1 with atomized liquid after the atomizing core 12 has consumed it. This not only allows the atomizer 1 to be reused but also improves the endurance of the vapor generator. In other words, the vapor generator provided in this embodiment has the advantage of a long continuous operating time. It should be noted that since the connection between the first housing 11 and the second housing 21 is detachable, after the atomized liquid in both the atomizer 1 and the reservoir 2 has been used up, simply detach the reservoir 2 from the atomizer 1 and then combine a new reservoir 2 pre-filled with atomized liquid with the original atomizer 1. This allows for continued replenishment of atomized liquid to the original atomizer 1.

[0072] Further, please refer to Figure 6 In some optional embodiments of this application, the volume of the second storage chamber 201 can be set to 2.5 to 5.5 times the volume of the first storage chamber 101. For example, assuming the volume of the first storage chamber 101 of the atomizer 1 is 2 ml (that is, it can store 2 ml of atomizing liquid), then the volume of the second storage chamber 201 of the reservoir 2 can be 5 ml to 11 ml, which is equivalent to indirectly increasing the volume of the atomizer 1 by 2.5 to 5.5 times. This setting not only allows the reservoir 2 to repeatedly replenish the atomizer 1 with atomizing liquid (at least 3 times), but also avoids the reservoir 2's volume being set too large, which would result in an excessively large overall size of the atomizing device and affect the user's portability.

[0073] Further, please refer to Figure 3-4 and Figure 18-21In some optional embodiments of this application, the first sidewall 111 is the circumferential sidewall of the first housing 11, and the second sidewall 211 is the circumferential sidewall of the second housing 21. For example, 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. The second housing 21 also includes a third sidewall 216 located differently from the second sidewall 211. The third sidewall 216 is provided with a through hole 2160. The vapor generating device also includes a driving component 32 provided corresponding to the through hole 2160. The through hole 2160 communicates with the mounting cavity 202 and is used to allow at least a portion of the driving component 32 to extend into it. The driving component 32 is configured to operably cause the valve 22 to move between a first position and a second position.

[0074] In this embodiment, the drive component 32 is configured to facilitate user operation of the valve 22 between the first and second positions. Specifically, when the atomizing liquid in the first storage chamber 101 of the atomizer 1 is depleted, the entire vapor generation device can be inverted (with the nozzle 13 facing downwards). Then, the drive component 32 is operated in the first manner, causing it to move the valve 22 from the first position to the second position. At this time, under the influence of gravity, the atomizing liquid in the second storage chamber can be introduced into the first storage chamber through the second liquid guide 210 for replenishment. After replenishment, the drive component 32 is operated in the second manner, causing the valve 22 to move from the second position back to the initial first position. At this time, the valve 22 isolates the first storage chamber 101 from the second storage chamber 201 to prevent the atomizing liquid in the first storage chamber 101 from flowing back into the second storage chamber 201.

[0075] Furthermore, in some optional embodiments of this application, the structure of valve 22 can be as follows:

[0076] Please refer to Figure 3-6 The second housing 21 has a partition portion 217 located between the mounting cavity 202 and the second storage cavity 201. The partition portion 217 has a liquid passage hole 2170 communicating with the second storage cavity 201. The valve 22 includes a sliding plate 221 slidably connected within the mounting cavity 202. The sliding plate 221 has a communication hole 2210 for communicating with the second liquid guiding portion 210 and the second storage cavity 201. Wherein, as... Figure 3 As shown, when the slide plate 221 is not driven by the drive component 32 and is in the first position, the slide plate 221 simultaneously covers the liquid outlet end of the liquid passage 2170 and the liquid inlet end of the second liquid guide part 210, thereby isolating the second liquid guide part 210 from the second storage cavity 201, and further isolating the first storage cavity 101 from the second storage cavity 201; as Figure 5As shown, when the slide plate 221 is driven by the driving component 32 to slide to the second position, the connecting hole 2210 of the slide plate 221 is simultaneously connected to the liquid outlet end of the liquid passage 2170 and the liquid inlet end of the second liquid guiding part 210, thereby connecting the second liquid guiding part 210 to the second storage cavity 201, so as to introduce the atomized liquid in the second storage cavity 201 into the first storage cavity 101 for replenishment. In this embodiment, the valve 22 provided in this embodiment has the advantage of simple structure.

[0077] Further, please refer to Figure 3-4 , Figure 8 In some optional embodiments of this application, the reservoir 2 further includes a first elastic member 23 located within the mounting cavity 202. One end of the first elastic member 23 abuts against the cavity wall of the mounting cavity 202, and the other end abuts against the sliding plate 221. The first elastic member 23 is configured to drive the sliding plate 221 back to a first position when the driving member 32 removes the force applied to the sliding plate 221.

[0078] In this embodiment, the first elastic element 23 is provided so that when the atomizing liquid in the first storage cavity 101 is replenished and the force applied to the slide plate 221 by the driving component 32 is removed, the slide plate 221 can automatically return to the first position without requiring the user to manually reset the slide plate 221, thereby improving the user experience. In specific implementations, the elastic element can be a spring, sheet metal, rubber band, or other component with good elastic properties, as long as it meets the usage requirements; this embodiment does not impose specific limitations on this.

[0079] Furthermore, in some optional embodiments of this application, to avoid wasting the atomizing liquid by allowing it to seep 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 atomizing liquid from the second storage cavity 201 into the first storage cavity 101, please refer to... Figure 13 and Figure 15 A first sealing element 25 is fixed on the side of the slide plate 221 facing the liquid passage hole 2170, which surrounds the liquid inlet end of the connecting hole 2210. A second sealing element 26 is fixed on the side of the slide plate 221 facing the second liquid guide part 210, which surrounds the liquid outlet end of the connecting hole 2210. Both the first sealing element 25 and the second sealing element 26 are in contact with the cavity wall of the mounting cavity 202.

[0080] In this embodiment, it should be noted that, in specific implementation, the material of the first sealing member 25 can be a sealing material such as silicone, rubber, or silicone rubber, and the first sealing member 25 can be fixed to the side of the slide plate 221 facing the liquid passage 2170 by embedding; similarly, the material of the second sealing member 26 can also be a sealing material such as silicone, rubber, or silicone rubber, and the second sealing member 26 can also be fixed to the side of the slide plate 221 facing the second liquid guiding part 210 by embedding. Furthermore, to better prevent the atomizing liquid from seeping into the mounting cavity 202 through the mounting gap between the slide plate 221 and the mounting cavity 202, thus avoiding waste of the atomizing liquid and corrosion of the second elastic element 325 by the atomizing liquid, preferably, the first sealing element 25 and the second sealing element 26 both extend along the sliding direction of the slide plate 221 (i.e., the height direction of the slide plate 221), so that regardless of whether the slide plate 221 is in the first position or the second position, the inner walls on the upper and lower sides of the liquid outlet end of the liquid passage hole 2170 in the mounting cavity 202 are in contact with the first sealing element 25, and the inner walls on the upper and lower sides of the liquid inlet end of the second liquid guiding part 210 in the mounting cavity 202 are in contact with the second sealing element 26.

[0081] Furthermore, in some optional embodiments of this application, the drive component 32 can be disposed on the reservoir 2 (in this case, the drive component 32 is part of the reservoir 2), and the structure of the drive component 32 can be a manual push structure. Specifically, please refer to... Figure 18-21 The drive component 32 includes a second push member 24 exposed on the second housing 21. The second push member 24 is slidably connected to the through hole 2160 of the second housing 21 and connected to the slide plate 221.

[0082] In this embodiment, it should be noted that the specific structural form of the second push member 24 can be a manually pressed button or a manually sliding push button, depending on the specific setting of the slide plate 221. For example, when the slide plate 221 is set 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 on the front or rear side wall of the second housing 21 (at this time, the third side wall 216 of the second housing 21 is the front or rear side wall of the second housing 21, and the first elastic member 23 can be clamped between the upper 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 connecting hole 2210 is located below the first liquid guiding part 110), or it can be a button exposed on the top wall of the second housing 21 (at this time, the first elastic member 23 can be clamped on the slide plate). The lower surface of the slide plate 221 is between the bottom wall of the mounting cavity 202, and when the slide plate 221 is in the first position, the connecting hole 2210 is located above the first liquid guiding part 110; for example, when the slide plate 221 is configured to slide back and forth along the width direction of the second housing 21, the second push member 24 can be a button exposed on the front side wall (or rear side wall) of the second housing 21. At this time, the first elastic member 23 is sandwiched between the rear surface of the slide plate 221 and the rear inner wall of the mounting cavity 202. When the slide plate 221 is in the first position, the connecting hole 2210 is located in front of the first liquid guiding part 110 (or the first elastic member 23 is sandwiched between the front surface of the slide plate 221 and the front inner wall of the mounting cavity 202, and when the slide plate 221 is in the first position, the connecting hole 2210 is located behind the first liquid guiding part 110).

[0083] In this embodiment, for ease of explanation of the relevant structural principles, the second pusher 24 is described as an exposed push button located on the front side wall of the second housing 21. Specifically, referring to the reference figures, after the atomizing liquid in the first storage chamber 101 of the atomizer 1 is consumed, the entire vapor generation device can be inverted, and then the second pusher 24 can be pushed with a finger along the direction close to the mouthpiece 13 (equivalent to the first operation mentioned in the previous embodiment), so that the slide plate 221 slides from the first position to the second position. At this time, 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 then under the action of gravity... The atomizing liquid in the second storage chamber can be sequentially introduced into the first storage chamber through the liquid passage 2170, the connecting hole 2210, and the second liquid guiding part 210 for replenishment. After replenishment, the finger is released, and under the elastic restoring force of the first elastic member 23, the slide plate 221 automatically returns to the first position and drives the second push member 24 to return to the initial 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 atomizing liquid in the first storage chamber 101 from flowing back into the second storage chamber 201. It should be noted that in some application scenarios, if the first elastic member 23 is removed, after replenishing the atomizing liquid in the second storage chamber 201 into the first storage chamber 101, the second push member 24 needs to be pushed back to the initial position with a finger in order to return the slide plate 221 to the first position. That is, if the first elastic member 23 is removed, the user needs to perform a separate reset operation on the slide plate 221.

[0084] Furthermore, in some alternative embodiments of this application, the driving component 32 can be disposed in the atomizing body (in this case, the driving component 32 is part of the atomizing body, specifically part of the power supply component 3 in the atomizing body), and the structure of the driving component 32 can be a push-type structure, as follows:

[0085] Please refer to Figure 1-6The atomizing body also includes a power supply component 3, which includes a battery 33, a control circuit board 34, and a third housing 31. The battery 33 and control circuit board 34 are both installed inside the third housing 31. The control circuit board 34 is electrically connected to the battery 33 and the atomizing core 12, respectively. The control circuit board 34 can control the battery 33 to supply power to the atomizing core 12, enabling the atomizing core 12 to perform atomization. One end of the third housing 31 along its height (i.e., the upper end of the third housing 31) is connected to the first housing 11, and the second housing 21 is detachably connected. The third sidewall 216 of the second housing 21 is the bottom wall of the second housing 21, and a through hole 3103 is provided on the part of the third housing 31 facing the third sidewall 216. The driving component 32 includes a first hand... The pusher 321, push rod 324, second elastic element 325 for resetting push rod 324, and lever 322 rotatably mounted in third housing 31 (exemplarily, a rotating shaft 323 is fixed in third housing 31, and lever 322 is rotatably sleeved on rotating shaft 323). The first pusher 321 has a pusher portion 3211 and a rod portion 3212 connected to each other. The pusher portion 3211 is slidably connected to the outer side wall of third housing 31 along the height direction of third housing 31. One end of rod portion 3212 away from pusher portion 3211 abuts against one end of lever 322. Push rod 324 is slidably mounted in third housing 31 along the height direction of third housing 31 (exemplarily, a longitudinal...). The mounting sleeve 326 is provided, and the push rod 324 slides longitudinally within the mounting sleeve 326. One end of the push rod 324 abuts against the end of the lever 322 away from the rod portion 3212 (exemplarily, the side wall of the mounting sleeve 326 has an opening 3260 facing the lever 322 and extending longitudinally, and the end of the lever 322 away from the rod portion 3212 passes through the opening 3260 and abuts against the lower end of the push rod 324). The other end of the push rod 324 is provided corresponding to the through hole 3103 (in specific implementation, when the push rod 324 is in the initial position, the upper end of the push rod 324 can extend into the through hole 3103, or it can be aligned with the lower end of the through hole 3103). The through hole 3103 is correspondingly connected to the through hole portion 2160 and is used for supplying... The push rod 324 passes through one end away from the lever 322. One end of the second elastic element 325 is fixed relative to the third housing 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 element 325 abuts against the upper inner wall of the mounting sleeve 326, and the other end of the second elastic element 325 abuts against one of the stepped surfaces of the push rod 324 that are opposite to the lever 322). When the push part 3211 is subjected to an external force to drive the lever 322 to rotate, the end of the push rod 324 away from the lever 322 passes through the through hole 3103 and extends into the through hole 2160 and abuts against the slide plate 221 to drive the slide plate 221 to slide from the first position to the second position.

[0086] 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 vapor generation 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.

[0087] 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.

[0088] In this embodiment, compared to placing the drive component 32 in the reservoir 2, the advantage of placing the drive component 32 in the power supply assembly 3 is that when the atomizing liquid in the reservoir 2 is consumed, the drive component 32 can be retained in the power supply assembly 3 for reuse, instead of being discarded when the reservoir 2 is replaced.

[0089] Furthermore, in some optional embodiments of this application, the driving component 32 can be disposed in the atomizing body (in this case, the driving component 32 is part of the atomizing body, specifically part of the power supply component 3 in the atomizing body), and the structure of the driving component 32 can be an electric structure, as follows:

[0090] Please refer to Figure 8-11 as well as Figure 13 The atomizing body also includes a power supply assembly 3, which includes a third housing 31, a battery 33, a control circuit board 34, and a control switch 35. One end of the third housing 31 along its height direction is connected to the first housing 11 and detachably connected to the second housing 21. The third sidewall 216 is the bottom wall of the second housing 21. A through hole 3103 is provided on the part of the third housing 31 facing the third sidewall 216. The battery 33 and the control circuit board 34 are both installed inside the third housing 31. The control circuit board 34 is electrically connected to the battery 33, the control switch 35, and the atomizing core 12. The control switch 35 is at least partially exposed outside the third housing 31. (Drive component 3) 2 includes a linear motor 327 and a push rod 324. The linear motor 327 is installed in the third housing 31 and electrically connected to the control circuit board 34. The push rod 324 is slidably installed in the third housing 31 along the height direction of the third housing 31 (exemplarily, a longitudinally arranged mounting sleeve 326 is provided in the third housing 31, and the push rod 324 is at least partially slidably fitted in the mounting sleeve 326). One end of the push rod 324 is fixedly connected to the output shaft of the linear motor 327, and the other end is provided corresponding to the through hole 3103. The through hole 3103 is correspondingly connected to the through hole 2160 and is used for the push rod 324 to pass through one end of the linear motor 327.

[0091] In this embodiment, it should be noted that the specific structural form of the control switch 35 can be a push-button switch, a slide switch, a touch switch, etc., which can be determined according to actual usage needs. This embodiment does not impose specific limitations on this. For ease of description, this embodiment uses a slide switch as an example to illustrate the structure of the control switch 35. Specifically, after the atomizing liquid in the first storage chamber 101 of the atomizer 1 is consumed by the atomizing core 12, the entire vapor generation device can be inverted first, and then a finger can be used along the first direction (e.g., 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.

[0092] In this embodiment, compared to such Figure 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.

[0093] Further, please refer to Figure 3-5In some optional embodiments of this application, a column portion 2211 protrudes from the side surface of the slide plate 221 facing the through hole portion 2160. The column portion 2211 is fitted into the through hole portion 2160 with a clearance. A first elastic member 23 is disposed on the side of the slide plate 221 facing away from the column portion 2211. With this configuration, during the movement of the push rod 324 in the direction close to the slide plate 221, when one end of the push rod 324 near the second housing 21 extends into the through hole portion 2160 of the second housing 21 and abuts against the column portion 2211 of the slide plate 221, the push rod 324 can push the column portion 2211 to make the entire slide plate 221 slide in the direction away from the through hole portion 2160. The column portion 2211 can play a guiding role, so that the slide plate 221 can slide more smoothly.

[0094] Furthermore, in some optional embodiments of this application, the connection between the first housing 11 and the third housing 31, and the connection between the second housing 21 and the third housing 31, can both be detachable snap-fit ​​connections, specifically:

[0095] Please refer to the reference. Figure 3 , Figure 10 , Figure 13 , Figure 17 as well as Figure 26-27The third housing 31 has a receiving cavity 310 at one end, in which at least a portion of the first housing 11 and at least a portion of the second housing 21 are received. A first locking hole 3101 is provided on the cavity wall of the receiving cavity 310 facing away from the first sidewall 111, and a second locking hole 3102 is provided on the cavity wall of the receiving cavity 310 facing away from the second sidewall 211. The outer wall of the first housing 11 facing away from the first sidewall 111 has a first groove 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 housing 11 is integrally connected, and the other end extends along the direction close to the bottom wall of the receiving cavity 310 and forms a first latching part 1131 facing away from the first groove 114. The first latching part 1131 is engaged with the first latching hole 3101 and can form a sliding contact with the hole wall of the first latching hole 3101 (for example, the top wall surface of the first latching hole 3101 is a first inclined surface that forms an obtuse angle with the cavity wall of the receiving cavity 310 facing away from the first side wall 111). Correspondingly, the first latching part 1131 has a face facing the first groove 114. The second inclined surface is provided with an inclined surface. There is a gap between the surface of the first elastic buckle 113 facing away from the first card hole 3101 and the groove wall surface of the first groove 114. The outer wall of the second housing 21 facing away from the second side wall 211 is provided with a second groove 214 and a second elastic buckle 213 made of plastic. One end of the second elastic buckle 213 is connected to the outer wall of the second housing 21 as a whole, and the other end extends along the direction close to the bottom wall of the receiving cavity 310 and forms a second card facing away from the second groove 214. The second latching part 2131 is engaged with the second latching hole 3102 and can form a sliding contact with the hole wall of the second latching hole 3102 (exemplarily, the top wall surface of the second latching hole 3102 is a third inclined surface that is set at an obtuse angle to the cavity wall of the receiving cavity 310 facing away from the second side wall 211, and correspondingly, the second latching part 2131 has a fourth inclined surface that faces the third inclined surface). There is a gap between the side surface of the second elastic latch 213 facing away from the second latching hole 3102 and the groove wall surface of the second groove 214.

[0096] In this embodiment, based on the above structural design, when combining the atomizer 1, the liquid reservoir 2, and the power supply assembly 3 into a complete vapor generation device, the first sidewall 111 of the atomizer 1 and the second sidewall 211 of the liquid reservoir 2 can be joined to form a combined atomizer. Then, the through hole 2160 of the second housing 21 corresponds to the through hole 3103 on the bottom wall of the receiving cavity 310. Finally, the bottom of the entire combined atomizer is inserted into the receiving cavity 310 of the third housing 31. During this process, the lower ends of the first elastic buckle 113 and the second elastic buckle 213 will be squeezed by the cavity wall of the receiving cavity 310. When deformation occurs until the first latching part 1131 is aligned with the first latching hole 3101 and the second latching part 2131 is aligned with the second latching hole 3102, the lower end of the first elastic latch 113 returns to its original state and the first latching part 1131 is fastened to the first latching hole 3101, and the lower end of the second elastic latch 213 returns to its original state and the second latching part 2131 is fastened to the second latching hole 3102. This achieves mutual fixation between the first housing 11 and the third housing 31, as well as between the second housing 21 and the third housing 31, so that the bottom of the entire combined atomizer can be stably kept in the receiving cavity 310 of the third housing 31 and is not easy to detach from each other. When the atomizing liquid in the reservoir 2 is depleted and a new reservoir 2 needs to be replaced, use your hand to pull the bottom of the combined atomizer out of the receiving cavity 310 of the third housing 31. Then, pry open the combined atomizer so that the atomizer 1 is separated from the old reservoir 2. Then repeat the previous assembly operations to combine the three modules of atomizer 1, new reservoir 2 and power supply component 3 into a new vapor generation device.

[0097] Furthermore, in some optional embodiments of this application, the circumferential portion of the first housing 11 corresponding to the first storage cavity 101 is made of a transparent material. Specifically, any circumferential sidewall of the first housing 11, except for the first sidewall 111, can be made of transparent materials such as glass or acrylic. This arrangement allows the user to easily observe the atomizing liquid content in the first storage cavity 101 at any time, so as to intuitively know whether the atomizing liquid in the first storage cavity 101 has been consumed and whether the first storage cavity 101 is full of atomizing liquid during the process of replenishing the atomizer 1 with atomizing liquid through the liquid reservoir 2.

[0098] Similarly, in some optional embodiments of this application, the circumferential portion of the second housing 21 corresponding to the second storage cavity 201 is made of a transparent material.

The first flange portion 115 and the second flange portion 215 are joined together to form an annular flange 4, which covers one end face of the third housing 31 where the receiving cavity 310 is located. This arrangement allows the annular flange 4 to cover the installation gaps between the first housing 11 and the third housing 31, as well as between the second housing 21 and the third housing 31, thereby improving the aesthetic appearance of the mist generating device.
