Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic cigarettes, in particular to a power supply device and an aerosol generating apparatus. BACKGROUND

[0002] Cigarette smoke contains harmful substances such as tar, and long-term inhalation of these harmful substances can cause great harm to the human body. In order to overcome the harmful substances generated by cigarette combustion, low-hazard cigarette substitutes such as e-cigarette and heat-not-burn e-cigarette have appeared.

[0003] Although the traditional electronic cigarette brings convenience, the use of a large number of electronic cigarettes can easily cause environmental pollution and resource waste, so the disassembly and recycling of electronic cigarettes are of great significance.

[0004] However, the already-conductive electronic components in the traditional electronic cigarette are prone to short circuit and other phenomena during disassembly, which in turn causes accidents such as heating, fire, and explosion. SUMMARY

[0005] Therefore, in view of the above problems, it is necessary to provide a power supply device and an aerosol generating apparatus.

[0006] A power supply device for supplying power to an atomization device of an aerosol generating apparatus, the power supply device comprising:

[0007] a tube body;

[0008] a battery arranged in the tube body, the battery having two poles with opposite polarities and being axially away from each other;

[0009] a conductive strip, two ends of the conductive strip being electrically connected to the two poles of the battery, respectively;

[0010] a top cover and a bottom cover, the top cover and the bottom cover being arranged on the two poles of the battery, respectively, and being capable of rotating relative to the tube body, at least one of the top cover and the bottom cover being provided with a cutting member for cutting the conductive strip, the conductive strip being located in a movement path of the cutting member.

[0011] The power supply device described above, when the related components (such as the battery and other electronic components) inside are to be recycled, the power supply device can be first separated from the atomization device, and then the top cover and the bottom cover of the power supply device are removed from the tube body, and various components inside are taken out for classification and recycling. During the disassembly of the top cover and the bottom cover, the top cover and the bottom cover can be operated relative to the tube body by using a special jig, and then the cutting member cuts the conductive strip, avoiding the risk of short circuit of the battery or other electronic components, ensuring the safety of the disassembly process and the integrity of the recycled parts.

[0012] In one of the embodiments, the bottom cover is provided with the cutting member, the cutting member comprises a cutting portion, one end of the cutting portion is connected with the bottom cover, and the other end of the cutting portion is suspended to form a cutting gap, and the cutting gap is used to cut the conductive strip. Such arrangement can be considered as that the cutting gap is aligned with the conductive strip, and when the bottom cover is rotated to be detached, the conductive strip is clamped into the cutting gap and cut off.

[0013] In one of the embodiments, the cutting portion is integrally formed with the bottom cover.

[0014] In one of the embodiments, the cutting member further comprises a ring portion arranged at the periphery of the bottom cover, one end of the ring portion is connected with the cutting portion, and the other end of the cutting portion is suspended to form a cutting gap at an angle with the ring portion.

[0015] In one of the embodiments, the cutting member further comprises a barrel portion embedded in the bottom cover, the barrel portion is connected with the ring portion, and the ring portion is fixed with the bottom cover through the barrel portion. After the bottom cover is detached, the cutting member can be easily separated from the bottom cover for classified recycling, because the cutting member is simply embedded in the bottom cover through the barrel portion.

[0016] In one of the embodiments, either one of the barrel portion and the bottom cover is provided with a limiting protrusion, and the other one is provided with a limiting recess, and the bottom cover is limited in the circumferential movement of the barrel portion through the cooperation of the limiting protrusion and the limiting recess. When the bottom cover is rotated to cut the conductive strip with the cutting portion of the cutting member, the cutting portion is resisted by the conductive strip, and the limiting protrusion and the limiting recess can ensure the fixing of the relative position of the barrel portion and the bottom cover, so that the bottom cover can effectively drive the barrel portion and the cutting portion connected therewith, thereby effectively cutting the conductive strip.

[0017] In one of the embodiments, the top cover is provided with the cutting member, the cutting member comprises a cutting portion, the conductive strip is located in the rotation path of the cutting portion, and one end of the cutting portion close to the conductive strip is a cutting end used to cut the conductive strip. The cutting end of the cutting portion can be a sharp sheet, and the present disclosure does not imply or indicate that the cutting end of the cutting portion can only be a sharp sheet, but the cutting end of the cutting portion can also be other relatively sharp shapes, as long as it can satisfy the better cutting effect on the conductive strip.

[0018] In one of the embodiments, the cutting member is integrally formed with the top cover.

[0019] In one of the embodiments, the cutting member comprises a supporting part connected with the cutting part, the supporting part is embedded in the inner circumferential surface of the top cover, and the inner circumferential surface of the top cover is provided with two clamping protrusions abutting against the two sides of the supporting part to limit the movement of the supporting part in the circumferential direction of the top cover. When the top cover rotates and drives the cutting part of the cutting member to cut the conductive strip, the cutting part is subjected to resistance from the conductive strip, and the arrangement of the two clamping protrusions can ensure the fixing of the relative position of the supporting part of the cutting member and the top cover, so that the top cover can effectively drive the supporting part and the cutting part connected with the supporting part, thereby effectively cutting the conductive strip.

[0020] In one of the embodiments, the outer circumferential surface of the top cover is further provided with an avoiding opening through which the conductive strip passes.

[0021] In one of the embodiments, the cutting part is provided in plurality, and the plurality of cutting parts are distributed at intervals in the circumferential direction of the power supply member. If a certain cutting part does not completely cut the conductive strip during the cutting process, other cutting parts can follow to ensure the cutting effect of the conductive strip.

[0022] In one of the embodiments, the power supply device further comprises a circuit board assembly arranged between the top cover and the battery, the circuit board assembly is electrically connected with one end of the conductive strip, and the conductive strip is electrically connected to one pole of the battery through the circuit board assembly.

[0023] The present application also relates to an aerosol generating device comprising an atomization device and the power supply device according to any one of the above embodiments, and the power supply device is electrically connected with the atomization device. The aerosol generating device can be a split type electronic cigarette, that is, the atomization device can be a cartridge, and the power supply device can be a cigarette rod with a power supply. For the user, the atomization device and the power supply device can be simply disassembled and replaced. The aerosol generating device can also be considered as a one-piece electronic cigarette, that is, a disposable electronic cigarette, and the atomization device is built-in in the tube.

[0024] In one of the embodiments, the atomization device is arranged to be separated from the power supply device under the action of external force. For example, in one embodiment, the aerosol generating device is a replaceable cartridge type electronic cigarette, and the atomization device can be directly pulled out from one end of the power supply device, that is, the cartridge can be pulled out from one end of the cigarette rod. For another example, in another embodiment, the aerosol generating device is a disposable electronic cigarette, that is, a one-piece electronic cigarette, and the atomization device is built-in in the tube. At this time, a special tool can be used to separate the atomization device from the power supply device. It can be understood that after the atomization device is removed, the top cover in the tube is exposed, so that the disassembly tool can be inserted into the tube to fix the top cover, thereby realizing subsequent disassembly.

[0025] The aforementioned aerosol generating equipment may include the power supply device described in the above embodiments. Therefore, it also has at least the following beneficial effects: when recovering relevant components (such as batteries and other electronic components) within the aerosol generating equipment, the power supply device can be separated from the atomizing device first, and then the top and bottom covers of the power supply device can be removed from the tube body to retrieve the various components inside for classified recycling. During the disassembly of the top and bottom covers, a specialized jig can be used to move the top and bottom covers relative to the tube body, thereby driving the cutting component to cut the conductive strip, avoiding the risk of short circuits in the battery or other electronic components, ensuring the safety of the disassembly process and the integrity of the recovered components.

[0037] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 This application provides a power supply device 11 for supplying power to the atomizing device 12 of an aerosol generating device 10. The power supply device 11 includes a tube body 100, a battery 200, a conductive strip 300, a circuit board assembly 400, a top cover 500, and a bottom cover 600. The battery 200 is disposed within the tube body 100 and is generally cylindrical with two poles of opposite polarity that are far apart along the axial direction. The circuit board assembly 400 includes a circuit board 410 and components such as electrode pins 420 and a microphone 430 electrically connected to the circuit board 410. The circuit board 410 is disposed between the top cover 500 and the battery 200, and the electrode pins 420 partially pass through the top cover 500 for electrical connection to the atomizing device 12. The microphone 430 can be used to detect changes in airflow or air pressure to activate the power supply device 11 when the user makes an inhalation action. The conductive strip 300 can be a conductive strip such as a nickel strip. Both ends of the conductive strip 300 are electrically connected to the two poles of the battery 200, and one end of the conductive strip 300 is electrically connected to the circuit board 410, meaning the conductive strip 300 is electrically connected to one pole of the battery 200 through the circuit board 410. The top cover 500 and the bottom cover 600 are respectively positioned over the two poles of the battery 200 and are rotatable relative to the tube body 100. The top cover 500 is positioned on the side of the circuit board 410 facing away from the battery 200. At least one of the top cover 500 and the bottom cover 600 is provided with a cutting element 700 for cutting the conductive strip 300, and the conductive strip 300 is located on the movement path of the cutting element 700.

[0039] When retrieving components (such as battery 200 and other electronic components) from the aforementioned power supply device 11, the power supply device 11 can be separated from the atomizing device 12 first. Then, the top cover 500 and bottom cover 600 of the power supply device 11 can be removed from the tube body 100, and the various components inside can be sorted and recycled. During the disassembly of the top cover 500 and bottom cover 600, a special jig can be used to move the top cover 500 and bottom cover 600 relative to the tube body 100, thereby driving the cutting component 700 to cut the conductive strip 300. This avoids the risk of short circuits in the battery 200 or other electronic components, ensuring the safety of the disassembly process and the integrity of the recovered components. It should be noted that the specific direction of movement of the cutting component 700 is not limited here. It can at least move along the axial or circumferential direction of the tube body 100, as long as the top cover 500 or bottom cover 600 can drive the cutting component 700 to move and cut the conductive strip 300 when being disassembled. For example, the cutting element 700 and the bottom cover 600 are separately arranged. The bottom cover 600 has an inclined driving surface, and the cutting element has a driven protrusion provided on the driving surface (not shown in the figure). When the bottom cover 600 is rotated, the rotation of the driving surface can push the protrusion and the cutting element 700 to move axially.

[0040] Please see Figure 4 , Figure 5 and Figure 6 In some embodiments, the bottom cover 600 is provided with a cutting element 700, which includes a cutting portion 710. One end of the cutting portion 710 is connected to the bottom cover 600, and the other end of the cutting portion 710 is suspended to form a slit 711. The slit 711 is used to cut the conductive strip 300, which is located on the rotation path of the slit 711. This arrangement can be considered as the slit 711 being aligned with the conductive strip 300. During disassembly, the bottom cover 600 is rotated to allow the conductive strip 300 to be inserted into the slit 711 and cut off. In one embodiment, the cutting portion 710 and the bottom cover 600 may be integrally formed.

[0041] Specifically, such as Figure 4 and Figure 5 As shown, in some embodiments, the cutting member 700 further includes a ring portion 720 disposed on the periphery of the bottom cover 600, the ring portion 720 being connected to one end of the cutting portion 710, and the other end of the cutting portion 710 being suspended to form a cut 711 at an angle α with the ring portion 720.

[0042] More specifically, such as Figure 4 , Figure 5 and Figure 6As shown, in some embodiments, multiple cutting portions 710 are provided, and the multiple cutting portions 710 are distributed circumferentially at intervals along the ring portion 720, that is, the multiple cutting portions 710 are distributed circumferentially at intervals along the power supply component. If, during the cutting of the conductive strip 300, one cutting portion 710 fails to completely cut the conductive strip 300, the other cutting portions 710 can follow immediately to ensure the cutting effect of the conductive strip 300.

[0043] More specifically, such as Figure 4 and Figure 5 As shown, in some embodiments, the cutting component 700 further includes a cylindrical portion 730 embedded in the bottom cover 600. The cylindrical portion 730 is connected to the ring portion 720, and the ring portion 720 is fixed to the bottom cover 600 via the cylindrical portion 730. After the bottom cover 600 is removed, since the cutting component 700 is simply embedded in the bottom cover 600 via the cylindrical portion, the cutting component 700 can be easily separated from the bottom cover 600 for classified recycling.

[0044] More specifically, such as Figure 5 As shown, in some embodiments, either the cylindrical portion 730 or the bottom cover 600 is provided with a limiting protrusion 810, and the other is provided with a limiting recess 820. The bottom cover 600 restricts the movement of the cylindrical portion 730 in the circumferential direction by the cooperation of the limiting protrusion 810 and the limiting recess 820. When the bottom cover 600 rotates and drives the cutting part 710 of the cutting member 700 to cut the conductive strip 300, the cutting part 710 is subjected to resistance from the conductive strip 300. The provision of the limiting protrusion 810 and the limiting recess 820 can ensure the fixation of the relative position of the cylindrical portion 730 and the bottom cover 600, ensuring that the bottom cover 600 can effectively drive the cylindrical portion 730 and the cutting part 710 connected to it, thereby effectively cutting the conductive strip 300.

[0045] Please see Figure 7 and Figure 8 In some embodiments, the top cover 500 is provided with a cutting element 700, which includes a cutting portion 710. The conductive strip 300 is located on the rotation path of the cutting portion 710, and the end of the cutting portion 710 near the conductive strip 300 is a cutting end, which is used to cut the conductive strip 300. The cutting end of the cutting portion 710 can be a sharp, thin sheet, etc. This is not to imply or indicate that the cutting end of the cutting portion 710 can only be a sharp, thin sheet; the cutting end of the cutting portion 710 can also be other relatively sharp shapes, as long as it can achieve a good cutting effect on the conductive strip 300. In one embodiment, the cutting element 700 and the top cover 500 can be integrally formed.

[0046] Specifically, such as Figure 8As shown, in some embodiments, the cutting member 700 further includes a support portion 740 connected to the cutting portion 710. The support portion 740 is embedded in the top cover 500, and is generally tile-shaped and fits against the inner circumferential surface of the top cover 500, which helps to save space. The inner circumferential surface of the top cover 500 is provided with two locking ribs, which abut against both sides of the support portion 740 to restrict the movement of the support portion 740 in the circumferential direction of the top cover 500. When the top cover 500 rotates and drives the cutting portion 710 of the cutting member 700 to cut the conductive strip 300, the cutting portion 710 is subjected to resistance from the conductive strip 300. The two locking ribs ensure that the relative position of the support portion 740 of the cutting member 700 and the top cover 500 is fixed, ensuring that the top cover 500 can effectively drive the support portion 740 and the cutting portion 710 connected thereto, thereby effectively cutting the conductive strip 300.

[0047] More specifically, such as Figure 7 and Figure 8 As shown, in some embodiments, the outer peripheral surface of the top cover 500 is also provided with a clearance opening 520 for the conductive strip 300 to pass through.

[0048] More specifically, in some embodiments, the top cover 500 may also have multiple cutting portions 710, which are distributed circumferentially around the top cover 500, i.e., the multiple cutting portions 710 are distributed circumferentially around the power supply component. If, during the cutting of the conductive strip 300, one cutting portion 710 fails to completely cut the conductive strip 300, the other cutting portions 710 can follow immediately to ensure the cutting effect of the conductive strip 300.

[0049] It should be noted that the top cover 500 and the bottom cover 600 can rotate relative to the tube body 100, which means that there are multiple connection methods between the top cover 500 and the tube body 100, and between the bottom cover 600 and the tube body 100. The following examples are for illustration only and do not indicate or imply that there are only a few connection methods.

[0050] Regarding the connection method between the bottom cover 600 and the tube body 100, for example, Figure 6 As shown, the bottom cover 600 and the tube body 100 are connected by a thread, allowing them to rotate relative to each other. Alternatively, in another embodiment, the bottom cover 600 can be rotatably engaged with the tube body 100. Yet another embodiment, the outer circumferential surface of the bottom cover 600 can be interference-fitted with the inner circumferential surface of the tube body 100, allowing the bottom cover 600 to rotate relative to the inner circumferential surface of the tube body 100 during disassembly, driven by an external fixture.

[0051] Regarding the connection method between the top cover 500 and the tube body 100, for example, the top cover 500 and the tube body 100 are connected by a thread, and the two can rotate relative to each other. Alternatively, in another embodiment, the top cover 500 can be rotatably snapped onto the tube body 100. Yet another embodiment, the outer circumferential surface of the top cover 500 can be interference-fitted with the inner circumferential surface of the tube body 100, and during disassembly, the top cover 500 is driven by an external fixture to rotate relative to the inner circumferential surface of the tube body 100.

[0052] In addition, such as Figure 1 and Figure 2 As shown, this application also relates to an aerosol generating device 10, which includes an atomizing device 12 and a power supply device 11 as described in any of the above embodiments, wherein the power supply device 11 is electrically connected to the atomizing device 12.

[0053] It should be noted that, in some embodiments, the aerosol generating device 10 can be considered as an integrated electronic cigarette, i.e., a disposable electronic cigarette, in which case the atomizing device 12 is built into the tube body 100. For example, as Figure 1 and Figure 2 As shown, in some embodiments, the tube 100 is generally cylindrical. The atomizing device 12 can be connected to the top of the tube 100 by means of bonding, ultrasonic welding, snap-fit, interference fit, etc. The methods of fixing the atomizing device 12 to the tube 100 are listed herein, but this is not a specific limitation on the connection method; it is intended to show that the connection method between the atomizing device 12 and the tube 100 is not detachable for the user. When the aerosol generating device 10 is a disposable electronic cigarette, i.e., an integrated electronic cigarette, with the atomizing device 12 built into the tube 100, a special jig can be used to separate the atomizing device 12 from the power supply device 11. That is, the atomizing device 12 is configured to be detachable from the power supply device 11 under external force. It is understood that after removing the atomizing device 12, the top cover 500 inside the tube 100 is exposed, allowing an external jig to be inserted into the tube 100 and fixed to the top cover 500, enabling subsequent disassembly.

[0054] In another embodiment, the aerosol generating device 10 can also be a split electronic cigarette, that is, the atomizing device 12 can refer to the cartridge, and the power supply device 11 can refer to the cigarette rod with a power supply. For the user, the atomizing device 12 and the power supply device 11 can be easily disassembled and replaced.

[0055] In some embodiments, the atomizing device 12 is configured to be detachable from the power supply device 11 under external force. For example, in one embodiment, when the aerosol generating device 10 is a refillable e-cigarette, the atomizing device 12 can be directly pulled out from one end of the power supply device 11, that is, the cartridge can be pulled out from one end of the e-cigarette. In another embodiment, when the aerosol generating device 10 is a disposable e-cigarette, i.e., an integrated e-cigarette, with the atomizing device 12 built into the tube body 100, a special jig can be used to separate the atomizing device 12 from the power supply device 11. It is understood that after removing the atomizing device 12, the top cover 500 inside the tube body 100 is exposed, allowing the disassembly jig to be inserted into the tube body 100 and fixed to the top cover 500 for subsequent disassembly.

[0056] The aforementioned aerosol generating device 10 may include a power supply device 11 as described in the embodiments above. Therefore, it also offers at least the following advantages: when recovering components (such as the battery 200 and other electronic components) within the aerosol generating device 10, the power supply device 11 can be separated from the atomizing device 12 first. Then, the top cover 500 and bottom cover 600 of the power supply device 11 can be removed from the tube 100, and the various components inside can be sorted and recycled. During the disassembly of the top cover 500 and bottom cover 600, a specialized jig can be used to move the top cover 500 and bottom cover 600 relative to the tube 100, thereby driving the cutting component 700 to cut the conductive strip 300. This avoids the risk of short circuits in the battery 200 or other electronic components, ensuring the safety of the disassembly process and the integrity of the recovered components.
