Description

Technical Field

[0001] This application relates to the field of electronic atomization device technology, and specifically to a power supply and electronic atomization device. Background Technology

[0002] Electronic atomizing devices typically include a power supply unit and an atomizer. The power supply unit supplies power to the atomizer, which has a reservoir cup and an atomizing coil. The reservoir cup and the atomizing coil are assembled to form a reservoir chamber and an atomization channel. The reservoir chamber is used to hold the atomized liquid, and the atomized liquid in the reservoir chamber can flow into the atomization channel in a measured amount. The atomized liquid flowing into the atomization channel is atomized into an aerosol by the atomizing coil and then flows out of the atomization channel to the outside of the atomizer.

[0003] In the related technologies known to the inventor, in order to prevent the atomizing liquid from overflowing from the atomizing channel to the outside of the atomizer, electronic atomizing devices typically include a switching structure. The switching structure is used to control the opening and closing of the liquid storage chamber and the atomizing channel. At least part of the switching structure is integrated with the atomizer. After the atomizing liquid in the atomizer is consumed, the structure integrated with the atomizer on the switching structure will be discarded along with the atomizer, which will cause resource waste. At the same time, since the atomizer not only includes the atomizing coil and the liquid storage cup, but also integrates at least part of the switching structure, it will increase the cost of the atomizer, resulting in higher costs for users to replace the atomizer. Summary of the Invention

[0004] The purpose of this application is to provide a power supply and an electronic atomizing device to solve the technical problem in the prior art where at least part of the on / off structure of the electronic atomizing device is integrated with the atomizer, resulting in resource waste and high cost for users to replace the atomizer.

[0012] In one embodiment, the movable sleeve has a second accommodating cavity extending axially. The movable sleeve is sleeved on the outside of the fixed sleeve and the push rod through the second accommodating cavity. The press-type telescopic assembly further includes a second elastic element, which is disposed in the second accommodating cavity. One end of the second elastic element abuts against the cavity wall of the second accommodating cavity, and the other end of the second elastic element causes the upper push rod to elastically abut against the lower push rod.

The power supply component can supply power to the atomizer, and the press-type telescopic component can control the opening and closing of the liquid storage chamber and atomization channel of the atomizer, so that the liquid storage chamber and atomization channel of the atomizer remain disconnected during transportation or other unused situations, minimizing the leakage of atomized liquid from the liquid storage chamber to the outside of the electronic atomizing device. Furthermore, compared with the case where the press-type telescopic component is integrated with the atomizer, the power supply provided in this application integrates the press-type telescopic component with the power supply component.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0043] The power supply 10 and electronic atomizing device provided in the embodiments of this application will now be described. Please refer to... Figure 1 , Figure 2 and Figure 10 The electronic atomizing device includes a power supply 10 and an atomizer 20.

[0044] Please see Figures 3 to 5 The atomizer 20 includes a liquid reservoir 21 and an atomizing core 22. The liquid reservoir 21 is movably sleeved on the outside of the atomizing core 22. A liquid reservoir 23 for storing atomized liquid is formed between the liquid reservoir 21 and the atomizing core 22. An atomizing channel 24 for gas flow is formed inside the atomizing core 22. The atomizing core 22 is also provided with a seepage hole 25 that connects the atomizing channel 24 and the liquid reservoir 23 (see [link]). Figure 5 ).

[0045] Please refer to the following: Figures 10 to 12 The power supply 10 provided in this embodiment includes a housing 100, a power supply assembly 200, and a push-to-open telescopic assembly 300. The housing 100 includes a first accommodating cavity 101 and a mounting opening 102 communicating with the first accommodating cavity 101. The mounting opening 102 is used for inserting the atomizer 20. The power supply assembly 200 and the push-to-open telescopic assembly 300 are both disposed in the first accommodating cavity 101. The power supply assembly 200 is used to supply power to the atomizer 20, and the push-to-open telescopic assembly 300 is used to drive the atomizing core 22 of the atomizer 20 to move up and down relative to the liquid storage cup 21, so that the liquid storage chamber 23 and the atomizing channel 24 of the atomizer 20 are connected or disconnected.

[0046] Specifically, the power supply assembly 200 and the push-to-retractable assembly 300 can be arranged in the first receiving cavity 101 with the power supply assembly 200 below and the push-to-retractable assembly 300 above, or they can be installed side-by-side at the same height in the first receiving cavity 101. The arrangement can be chosen as needed, and this embodiment does not impose any limitations on this. Preferably, when the power supply assembly 200 includes a power source 210 and a power supply electrode 220, the power source 210 can be positioned below the push-to-retractable assembly 300, and the power supply electrode 220 can be positioned above the push-to-retractable assembly 300, with both the power supply electrode 220 and the push-to-retractable assembly 300 facing the mounting opening 102.

[0047] Specifically, please refer to Figure 12 The housing 100 may include an outer shell 110, a first inner shell 120, and a second inner shell 130. The top of the outer shell 110 is open. The first inner shell 120 and the second inner shell 130 are respectively detachably disposed inside the outer shell 110. The first accommodating cavity 101 formed by assembling the outer shell 110, the first inner shell 120, and the second inner shell 130 includes an upper cavity 1011 and a lower cavity 1012 disposed vertically. The upper cavity 1011 is used to install the power supply electrode 220 of the press-type telescopic component 300 and the power supply component 200. The lower cavity 1012 is used to accommodate the power supply 210 of the power supply component 200. This design facilitates the overall disassembly and assembly of the press-type telescopic component 300 and the power supply electrode 220 by disassembling and assembling the first inner shell 120, improving disassembly and assembly efficiency. In case of fault repair, a single component can be repaired or replaced, reducing usage costs. Furthermore, placing the press-type telescopic component 300 and the power supply electrode 220, which need to be connected to the atomizer 20, near the open end of the outer shell 110 simplifies the connection structure between the press-type telescopic component 300 and the atomizing core 22, as well as the connection structure between the power supply electrode 220 and the atomizing electrode 26 of the atomizer 20, reducing connection failures between various components and resulting in good product consistency.

[0048] The power supply 10 provided in this application, please refer to [link / reference]. Figure 8 and Figure 9 When the atomizer 20 is operating normally, the power supply unit 200 supplies power to the atomizer 20. The push-button telescopic component 300 drives the atomizing core 22 to move to a position where the liquid seepage hole 25 connects the liquid storage chamber 23 and the atomization channel 24. The atomized liquid flows into the atomization channel 24 through the liquid seepage hole 25. The atomized liquid flowing into the atomization channel 24 is atomized into an aerosol by the atomizing core 22. The aerosol flows out through the atomization channel 24 to the outside of the atomizer 20, where it can be inhaled by the user. Please refer to [link to relevant documentation]. Figures 4 to 7 When the atomizer 20 is being transported, stored, or otherwise unused, the power supply component 200 stops supplying power to the atomizer 20. The press-type telescopic component 300 drives the atomizing core 22 to move until the leakage hole 25 is blocked by the inner wall of the liquid storage cup 21 or the leakage hole 25 is completely moved out of the liquid storage chamber 23. This isolates the liquid storage chamber 23 from the atomization channel 24, and the atomized liquid is sealed inside the liquid storage chamber 23. This prevents the atomized liquid from overflowing from the atomization channel 24 to the outside of the atomizer 20, and also prevents the atomizing core 22 from being soaked in the atomized liquid, which could lead to deterioration of the atomized liquid.

[0049] Furthermore, compared to the case where the press-type telescopic component 300 is integrated with the atomizer 20, the power supply 10 provided in this application integrates the press-type telescopic component 300 with the power supply component 200 into one unit. After the atomizing liquid of the atomizer 20 is consumed, only the atomizer 20 needs to be replaced. The entire structure of the press-type telescopic component 300 can be reused, which can avoid wasting resources and reduce the cost for users to replace the atomizer 20.

[0050] Secondly, the press-type telescopic component 300 is integrated into the power supply 10, which does not occupy the space of the atomizer 20, allowing the capacity of the liquid storage chamber 23 to be designed to be larger, the service life of each atomizer 20 to be longer, reducing the number of times the atomizer 20 and the power supply 10 are disassembled and reassembled, and extending the service life of the power supply 10.

[0051] Furthermore, compared to the case where the press-type telescopic component 300 is located in the atomizer 20, the press-type telescopic component 300 is integrated into the power supply 10. The press-type telescopic component 300 is less likely to come into contact with the atomizing liquid, aerosol, and user inhalation operation, and is less susceptible to gas and liquid corrosion and operational wear, which helps to improve the service life of the press-type telescopic component 300.

[0052] In another embodiment of this application, please refer to Figure 12 The press-type telescopic assembly 300 includes a fixed sleeve 310, a push rod 320, a movable sleeve 330, and a first elastic element 340. The bottom end of the fixed sleeve 310 abuts against the cavity wall of the first accommodating cavity 101, specifically, it can abut against the bottom wall of the upper cavity 1011; the bottom end of the push rod 320 is movably sleeved inside the fixed sleeve 310, and the top end of the push rod 320 is used to connect to the atomizing core 22; the bottom end of the movable sleeve 330 is movably sleeved outside the fixed sleeve 310, and the top end of the movable sleeve 330 is used to abut against the liquid storage cup 21 of the atomizer 20; the first elastic element 340 abuts between the bottom end of the movable sleeve 330 and the cavity wall of the first accommodating cavity 101; the movable sleeve 330 can drive the push rod 320 to switch between a first height position and a second height position under the cooperative action of the fixed sleeve 310 and the first elastic element 340.

[0053] Specifically, in this embodiment, the push rod 320 can be configured as a single element. When configured as a single element, the push rod 320 moves up and down as a whole, and rotates as a whole when rotating. The push rod 320 can also be configured as multiple elements, such as the lower push rod 321 and the upper push rod 322 as described below. The lower push rod 321 can drive the upper push rod 322 to move up and down, but when the lower push rod 321 rotates, it will not drive the upper push rod 322 to rotate. In this case, when the upper push rod 322 is directly connected to the atomizing core 22, the atomizing core 22 will only move up and down with the push rod 320 and will not rotate, which helps to simplify the electrical connection structure between the atomizing core 22 and the power supply component 200.

[0054] Specifically, in this embodiment, the push rod 320 may be provided with a structure similar to or the same as the sliding claw sleeve in a press-type ballpoint pen, the fixed sleeve 310 may be provided with a structure similar to or the indexing claw in a press-type ballpoint pen, and the movable sleeve 330 may be provided with a structure similar to or the same as the guide structure inside the pen barrel in a press-type ballpoint pen. Of course, the fixed sleeve 310, push rod 320, and movable sleeve 330 may also be configured with other structures as needed, as long as the movable sleeve 330 can drive the push rod 320 to switch between the first height position and the second height position under the cooperative action of the fixed sleeve 310 and the first elastic element 340.

[0055] The power supply 10 provided in this embodiment allows the push rod 320 to switch between a first height position and a second height position once by pressing and releasing the movable sleeve 330. Thus, when the push rod 320 is connected to the atomizing core 22 of the atomizer 20, pressing and releasing the movable sleeve 330 once by the liquid reservoir 21 allows the liquid reservoir 23 and the atomizing channel 24 to switch between a conductive state and a disconnected state once. This allows the user to conveniently change the on / off state of the liquid reservoir 23 and the atomizing channel 24 according to the usage status of the atomizer 20.

[0056] In another embodiment of this application, please refer to Figure 13 and Figure 14 The inner wall of the movable sleeve 330 is provided with multiple alternating anti-slip grooves 331 and multiple sliding grooves 332 extending axially along the movable sleeve 330. The top of the anti-slip groove 331 is open and the bottom is closed, and the bottom wall of the anti-slip groove 331 is a first guide slope 3311. The top of the sliding groove 332 is open, and the bottom of the sliding groove 332 extends below the first guide slope 3311. An isolation ridge 333 is provided between adjacent anti-slip grooves 331 and sliding grooves 332. The top of the isolation ridge 333 is a second guide slope 3331 with an inclination direction approximately the same as the first guide slope 3311. The top of the fixed sleeve 310 is provided with serrated meshing teeth 311. Please refer to the reference. Figure 12 The push rod 320 includes an upper push rod 322 and a lower push rod 321. The lower push rod 321 is movably sleeved in the fixed sleeve 310. The outer wall of the lower push rod 321 is provided with a rod guide block 3211. The bottom wall of the rod guide block 3211 is a third guide slope 3212. The bottom end of the upper push rod 322 elastically abuts against the top end of the lower push rod 321. The top end of the upper push rod 322 is used to connect the atomizing core 22.

[0057] When the push rod 320 is in the first height position, the rod guide block 3211 is slidably sleeved in the anti-slip groove 331, and the third guide inclined surface 3212 abuts against the first guide inclined surface 3311; when the push rod 320 is in the second height position, the rod guide block 3211 is slidably sleeved in the through groove 332, and the third guide inclined surface 3212 abuts against the tooth surface of the meshing tooth 311. The lowest point when the third guide inclined surface 3212 abuts against the tooth surface of the meshing tooth 311 is lower than the lowest point when the third guide inclined surface 3212 abuts against the first guide inclined surface 3311; the first guide inclined surface 3311, the second guide inclined surface 3331, and the tooth surface of the meshing tooth 311 are used to guide the rod guide block 3211 to switch between the anti-slip groove 331 and the through groove 332.

[0058] To facilitate understanding and explanation, the principle of the push-type telescopic assembly 300 controlling the opening and closing of the liquid storage chamber 23 and the atomizing channel 24 will be explained with the push rod 320 in the second height position at a lower height as the initial state.

[0059] When the push rod 320 is in the second height position, the rod guide block 3211 that abuts against the push rod 321 is slidably sleeved in the through groove 332 of the fixed sleeve 310. The bottom wall (third guide inclined surface 3212) of the rod guide block 3211 abuts against the upper part of the tooth surface of the first meshing tooth 311. In other words, the lowest point of the rod guide block 3211 is higher than the lowest point of the first meshing tooth 311.

[0060] When the movable sleeve 330 is pushed downward for the first time by an external force, the first elastic element 340 is compressed. The rod guide block 3211 of the lower push rod 321 will disengage from the through groove 332 of the movable sleeve 330 after the movable sleeve 330 moves down a certain distance. At the same time, the lower push rod 321 rotates under the pressure of the upper push rod 322 and the guidance of the tooth surface of the first meshing tooth 311. The lower push rod 321 will rotate until the lowest point of the rod guide block 3211 abuts against the lowest point of the first meshing tooth 311, and the rod guide block 3211 rotates from being aligned with the through groove 332 to being aligned with the anti-slip groove 331.

[0061] When the external force is released, the compressed first elastic element 340 rebounds. When the movable sleeve 330 moves upward relative to the fixed sleeve 310 by a certain distance under the elastic force of the first elastic element 340, the bottom wall of the anti-slip groove 331 (first guide slope 3311) abuts against the bottom wall of the rod guide block 3211 (third guide slope 3212). The lower push rod 321 rotates under the pressing action of the upper push rod 322 and the guiding action of the bottom wall of the anti-slip groove 331 (first guide slope 3311). After rotation, the lowest point of the rod guide block 3211 of the lower push rod 321... When the lowest point of the anti-slip groove 331 abuts, and the first elastic member 340 rebounds to a state where it is not pressed by external force, the upper push rod 322 moves upward to the first height position under the pushing action of the lower push rod 321. When the upper push rod 322 rises from the second height position to the first height position, the upper push rod 322 will drive the atomizing core 22 to move upward a certain distance, which can switch the liquid storage chamber 23 and the atomizing channel 24 from the disconnected state to the connected state. Of course, in other embodiments, by setting the position of the seepage through hole 25, the liquid storage chamber 23 and the atomizing channel 24 can also be switched from the connected state to the disconnected state.

[0062] When the movable sleeve 330 is pushed downward for the second time using external force, the first elastic element 340 is compressed. The rod guide block 3211 of the lower push rod 321 will disengage from the anti-slip groove 331 after the movable sleeve 330 moves down a certain distance. The lower push rod 321 will slide into the second meshing tooth 311 adjacent to the first meshing tooth 311 under the pressing action of the upper push rod 322. Under the guidance of the tooth surface of the second meshing tooth 311, it will rotate until the lowest point of the rod guide block 3211 abuts against the lowest point of the second meshing tooth 311. The rod guide block 3211 will no longer be aligned with the through groove 332, but will be aligned with the top end of the isolation protrusion 333 (the second guide inclined surface 3331).

[0063] When the external force is released again, the compressed first elastic element 340 rebounds. When the movable sleeve 330 moves upward relative to the fixed sleeve 310 by a certain distance under the elastic force of the first elastic element 340, the top end of the isolating protrusion 333 (second guide slope 3331) abuts against the bottom wall (third guide slope 3212) of the rod guide block 3211. The lower push rod 321 rotates under the pressing action of the upper push rod 322 and the guiding action of the top end of the isolating protrusion 333 (second guide slope 3331). After rotation, the rod guide block 3211 of the lower push rod 321... When the upper push rod 322 slides back into the through groove 332, and the first elastic element 340 rebounds to a state where it is not pressed by external force, the upper push rod 322 moves down to the second height position under the pushing action of the lower push rod 321. When the upper push rod 322 moves down from the first height position to the second height position, the upper push rod 322 will drive the atomizing core 22 to move down a certain distance, which can switch the liquid storage chamber 23 and the atomizing channel 24 from the connected state to the disconnected state. Of course, in other embodiments, by setting the position of the seepage through hole 25, the liquid storage chamber 23 and the atomizing channel 24 can also be switched from the disconnected state to the connected state.

[0064] As described above, the power supply 10 provided in this embodiment can switch the push rod 320 between the first height position and the second height position once by pressing and releasing the movable sleeve 330 once. In this way, when the upper push rod 322 is connected to the atomizing core 22 of the atomizer 20, the liquid storage cup 21 can switch the liquid storage chamber 23 and the atomizing channel 24 between the on and off states once by pressing and releasing the movable sleeve 330 once. This allows the user to conveniently change the on / off state of the liquid storage chamber 23 and the atomizing channel 24 according to the usage state of the atomizer 20.

[0065] In another embodiment of this application, please refer to Figure 13 and Figure 14 The outer wall of the fixed sleeve 310 is provided with at least one pipe guide block 312, which is slidably installed in the through groove 332.

[0066] Specifically, the number of pipe guide blocks 312 can be one, two, etc., and the number of pipe guide blocks 312 is less than or equal to the number of through grooves 332.

[0067] The power supply 10 provided in this embodiment, after the tube guide block 312 is slidably installed in the through groove 332, can keep the fixed sleeve 310 and the movable sleeve 330 fixed in the circumferential direction, so that the fixed sleeve 310 can more stably guide the movement of the push rod 321.

[0068] In another embodiment of this application, please refer to Figure 12The movable sleeve 330 is provided with a second receiving cavity 334 that extends through the movable sleeve 330 along its axial direction. The movable sleeve 330 is sleeved on the outside of the lower push rod 321, the upper push rod 322 and the fixed sleeve 310 through the second receiving cavity 334. The second elastic member 350 is provided in the second receiving cavity 334. One end of the second elastic member 350 abuts against the cavity wall of the second receiving cavity 334, and the other end of the second elastic member 350 elastically abuts the bottom end of the upper push rod 322 against the top end of the lower push rod 321.

[0069] In this embodiment, the power supply 10 has a second elastic element 350 that allows the upper push rod 322 to elastically abut against the lower push rod 321. In other words, the upper push rod 322 moves up and down only under the pushing action of the lower push rod 321, and does not rotate with the rotation of the lower push rod 321. Thus, when the upper push rod 322 is connected to the atomizing core 22 of the atomizer 20, the upper push rod 322 will only drive the atomizing core 22 to move up and down, and will not drive the atomizing core 22 to rotate. The atomizing core 22 only moves up and down without rotating, which helps to simplify the electrical connection structure between the power supply assembly 200 and the atomizing core 22, and makes the electrical connection more stable. Furthermore, by placing the second elastic element 350 in the space between the movable sleeve 330 and the upper push rod 322, the structure of the power supply 10 is more compact.

[0070] In another embodiment of this application, please refer to Figure 12 The movable sleeve 330 includes a first movable seat 335 and a second movable seat 336 that are detachably connected. The first movable seat 335 abuts against the top of the first elastic member 340 and is sleeved on the outside of the fixed sleeve 310. The second movable seat 336 abuts against the top of the first movable seat 335 and is sleeved on the outside of the upper push rod 322. The first movable seat 335 and the second movable seat 336 together form a second receiving cavity 334. One end of the second elastic member 350 abuts against the second movable seat 336, and the other end of the second elastic member 350 presses the bottom end of the upper push rod 322 against the top of the first movable seat 335 and the top of the lower push rod 321.

[0071] Specifically, the first movable seat 335 and the second movable seat 336 can be fixedly connected as one unit by means of snap-fit, threaded connection, adhesive bonding, etc., and can be set as needed. This embodiment does not limit this.

[0072] For example, the first movable seat 335 includes a first annular side plate 3351, a first flat plate 3352, and a second annular side plate 3353. The first annular side plate 3351 is sleeved on the outside of the fixed sleeve 310. The first flat plate 3352 is annular and is connected to the outer periphery of the first annular side plate 3351 and is approximately perpendicular to the axial direction of the first annular side plate 3351. The second annular side plate 3353 is cylindrical and is connected to the outside of the first flat plate 3352, and its axial direction is approximately coincident with the axial direction of the first annular side plate 3351. The inner side of the first annular side plate 3351 is provided with an anti-slip groove 331, a sliding groove 332, and an isolation protrusion 333. The second movable seat 336 includes a second flat plate 3361 and a third annular side plate 3362. The second flat plate 3361 is connected to one end of the third annular side plate 3362, and the end of the third annular side plate 3362 away from the second flat plate 3361 is connected to the second annular side plate 3353. The second flat plate 3361 has an opening for the upper push rod 322 to pass through to the outside of the inner cavity. The bottom end of the upper push rod 322 abuts against the first flat plate 3352, the top end of the second elastic member 350 abuts against the second flat plate 3361, and the bottom end of the second elastic member 350 abuts against the bottom end of the upper push rod 322.

[0073] The power supply 10 provided in this embodiment has a movable collar configured as a first movable seat 335 and a second movable seat 336 that can be detachably connected. This simplifies the manufacturing process of the movable sleeve 330. Also, if either the first movable seat 335 or the second movable seat 336 is damaged, only one of them needs to be replaced, reducing the cost of use. It also facilitates the installation of the upper push rod 322, the lower push rod 321, and the second elastic member 350 in the second accommodating cavity 334, thereby improving the assembly efficiency of the power supply 10.

[0074] In another embodiment of this application, please refer to Figure 12 The first accommodating cavity 101 has a positioning element 103 on its side wall, which restricts the movable sleeve 330 from moving towards the mounting opening 102. This arrangement prevents the movable sleeve 330 from detaching from the housing 100 under the elastic force of the first elastic element 340, thus ensuring the stability of the movable sleeve 330.

[0075] In another embodiment of this application, please refer to Figure 15 The top of the push rod 320 is provided with a first snap-fit ​​structure, which is used to snap-fit ​​with the atomizing core 22 of the atomizer 20.

[0076] Specifically, the first snap-fit ​​structure can be a snap-fit ​​and / or a slot, which can be set as needed, and this embodiment does not limit this.

[0077] For example, when the push rod 320 is configured as a cylindrical structure, the first locking structure includes a first locking groove 3221. The first locking groove 3221 includes a first locking segment 3222 and a second locking segment 3223. The first locking segment 3222 extends axially along the push rod 320 and has an open top. The second locking segment 3223 is connected to the bottom of the first locking segment 3222 and extends circumferentially along the push rod 320. Correspondingly, please refer to [link to relevant documentation]. Figure 2 The outer wall of the bottom end of the atomizing core 22 is provided with a first locking pin 221. When assembling the push rod 320 and the atomizing core 22, the first locking pin 221 of the atomizing core 22 can be first inserted into the first locking segment 3222, and the atomizing core 22 can be moved down until the first locking pin 221 moves to the end of the second locking segment 3223 close to the first locking segment 3222. Then, the atomizing core 22 is rotated so that the first locking pin 221 moves to the end of the second locking segment 3223 away from the first locking segment 3222, so that the atomizing core 22 is locked on the top of the push rod 320.

[0078] The power supply 10 provided in this embodiment has a first snap-fit ​​structure at the top of the push rod 320, so that the push rod 320 can be connected to the atomizing core 22 by snap-fit. The snap-fit ​​operation is more convenient and the connection is more stable.

[0079] In another embodiment of this application, please refer to Figure 10 and Figure 12 The top of the housing 100 is provided with a second snap-fit ​​structure, which includes a second snap-fit ​​groove 104. The second snap-fit ​​groove 104 includes a first snap-fit ​​segment 1041, a second snap-fit ​​segment 1042, and a third snap-fit ​​segment 1043 connected in sequence. The first snap-fit ​​segment 1041 extends axially along the housing 100 and has an open top. The second snap-fit ​​segment 1042 extends circumferentially along the housing 100. The axial dimension of the second snap-fit ​​segment 1042 in the housing 100 is equal to the sum of the height of the second snap-fit ​​pin 281 and the height of the third snap-fit ​​pin 211 of the atomizer 20. The third snap-fit ​​segment 1043 extends from the end of the second snap-fit ​​segment 1042 away from the first snap-fit ​​segment 1041 along the axial direction of the housing 100 in a direction away from the first snap-fit ​​segment 1041. It can be understood that the axial direction of the housing 100 is the direction from the bottom to the top of the housing 100. Figure 10 The X direction shown in the figure), the circumferential direction of the housing 100 is the direction surrounding the axial direction of the housing 100 ( Figure 10 (The direction surrounding the X direction).

[0080] It should be noted that you should refer to [link / reference]. Figure 5The atomizer 20 applicable to the power supply 10 provided in this embodiment also includes a mounting sleeve 28. The mounting sleeve 28 is sleeved on the outside of the liquid storage cup 21. The mounting sleeve 28 can move relative to the liquid storage cup 21 along the axial direction of the liquid storage cup 21, and the mounting sleeve 28 and the liquid storage cup 21 are fixed in the circumferential direction of the liquid storage cup 21. Specifically, the mounting sleeve 28 includes a first connecting section 282, a step 283, and a second connecting section 284 connected in sequence and in a stepped shape. The inner diameter of the second connecting section 284 is smaller than the inner diameter of the first connecting section 282. The outer wall of the liquid storage cup 21 is provided with a sliding groove 212. The second connecting section 284 and the sliding groove 212 are connected along the axial direction of the liquid storage cup 21. Figure 5 (The X-direction shown) sliding fit. And, please refer to... Figure 2 The outer wall of the second connecting section 284 is provided with a second locking pin 281. The outer wall of the liquid storage cup 21 is provided with a third locking pin 211. The second locking pin 281 and the third locking pin 211 are arranged sequentially along the axial direction of the liquid storage cup 21. The second locking pin 281 is located above the third locking pin 211. In other words, after the atomizer 20 and the power supply 10 are assembled, the third locking pin 211 is closer to the power supply 10. The height of the third locking pin 211 can be understood as the dimension of the third locking pin 211 in the axial direction of the liquid storage cup 21, and the height of the second locking pin 281 can be understood as the dimension of the second locking pin 281 in the axial direction of the mounting sleeve 28.

[0081] Please refer to the power supply 10 provided in this embodiment. Figure 2 and Figure 10 When assembling with the atomizer 20, the second locking pin 281 and the third locking pin 211 can be simultaneously engaged into the first locking slot section 1041, and the mounting sleeve 28 and the liquid reservoir 21 can be simultaneously lowered until the second locking pin 281 and the third locking pin 211 have both moved down to the end of the second locking slot section 1042 near the first locking slot section 1041, and the platform section 283 of the mounting sleeve 28 abuts against the top surface of the housing 100; then, the mounting sleeve 28 is rotated, and the mounting sleeve 28 drives the liquid reservoir 21 to rotate synchronously, so that the second locking pin 281... Both the third locking pin 211 and the second locking segment 1042 are moved to the end away from the first locking segment 1041. In this way, the mounting sleeve 28 and the housing 100 are locked together. The mounting sleeve 28 cannot move up and down relative to the housing 100, but at the same time, the third locking pin 211 retains the freedom to move up and down in the third locking segment 1043. That is, the freedom to move up and down of the liquid storage cup 21 is retained, and the up and down movement of the liquid storage cup 21 can be guided and limited, so that the press-type telescopic component 300 can be driven by pressing the liquid storage cup 21.

[0082] In another embodiment of this application, please refer to Figure 7The press-type telescopic assembly 300 also includes a magnetic element 360, which is disposed on the surface of the movable sleeve 330 facing the mounting opening 102. The magnetic element 360 is used to magnetically fix the atomizer 20.

[0083] Specifically, the number of magnetic components 360 can be one, two, etc., and the magnetic components 360 can be magnetically attracted to the magnetic mating components 27 on the liquid storage cup 21.

[0084] The power supply 10 provided in this embodiment has a magnetic component 360 on the top surface of the movable sleeve 330. In this way, after the power supply 10 and the atomizer 20 are assembled, the magnetic component 360 will be magnetically attracted to the magnetic mating component 27 of the atomizer 20, which can make the connection between the power supply 10 and the atomizer 20 more stable.

[0085] In another embodiment of this application, please refer to Figure 4 and Figure 5 The power supply assembly 200 includes a power supply 210 and a power supply electrode 220. The power supply 210 is located at the bottom of the first accommodating cavity 101, and the press-type telescopic assembly 300 is located at the top of the power supply 210. The power supply electrode 220 is located on the surface of the movable sleeve 330 facing the mounting opening 102. One end of the power supply electrode 220 is electrically connected to the power supply 210, and the other end of the power supply electrode 220 is used to electrically connect to the atomizing electrode 26 of the atomizer 20.

[0086] The power supply 10 provided in this embodiment has a power supply electrode 220 located on the top of the press-type telescopic assembly 300, and a power supply 210 located on the top of the press-type telescopic assembly 300. In this way, after the power supply 10 and the atomizer 20 are assembled, the power supply electrode 220 of the power supply 10 will be directly electrically connected to the atomizing electrode 26 of the atomizer 20 by abutting. The press-type telescopic assembly 300 can also directly drive the atomizing core 22 of the atomizer 20 to move up and down. The overall structure is reasonably laid out, and the connection with the atomizer 20 is more convenient.

[0087] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
