Description

Technical Field

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

[0002] Aerosol generators include an atomizer and a power supply. The atomizer contains an atomizing medium and a heating element for heating the atomizing medium to form an aerosol that can be inhaled by the user. The power supply is electrically connected to the atomizer to provide power to the heating element. In related technologies, most aerosol generators are one-piece structures that are discarded after use. The battery is encapsulated inside, requiring forceful disassembly (such as damaging the device casing and other components) to remove it. This makes it inconvenient to disassemble, replace, or recycle the battery, easily leading to resource waste. Utility Model Content

[0003] In view of this, this application provides a power supply device and an aerosol generating device to achieve battery removal without damaging the button and the casing.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0013] Optionally, the sleeve is provided with a clearance hole, and the bracket is provided with a clearance recess corresponding to the clearance hole. When the button body moves toward the sleeve, the limiting buckle passes through the clearance hole and approaches the clearance recess.

[0014] Optionally, the elastic element includes a main body and a rebound support connected to the main body. The main body abuts against the switch, and the rebound support abuts against the outer wall of the sleeve. The button body has a pressing protrusion on the side facing the sleeve, and the pressing protrusion is inserted into the pressing groove on the main body.

[0015] Optionally, the power supply device further includes an end connector, through which the second end of the housing, the fourth end of the bracket, and the sixth end of the sleeve are connected and engaged.

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] like Figures 1-4As shown, the power supply device 100 provided in this application includes: a housing 110, a bracket 120, and a button. The housing 110 has a cylindrical structure and has a first end 111 and a second end 112 arranged opposite each other in the longitudinal direction. Both the first end 111 and the second end 112 have openings. A button hole 113 is provided on the housing 110. The bracket 120 passes through the inner cavity of the housing 110 and has a receiving space. The battery body 150 is detachably installed in the receiving space of the bracket 120. The bracket 120 has a third end 121 and a fourth end 122 arranged opposite each other in the longitudinal direction. The third end 121 of the bracket 120 is close to the first end 111 of the housing 110, and the fourth end 122 of the bracket 120 is close to the second end 112 of the housing 110. The button passes through the button hole 113 and is connected to the bracket. Corresponding to the power switch 125 on the bracket 120, the button is provided with a limiting structure to prevent the button from falling out of the button hole 113. Thus, when the button is pressed, the button can approach and abut against the power switch 125, and the limiting structure prevents the button from falling out of the button hole 113 and onto the outside of the housing 110. There is a radial gap between the button and the bracket 120, so when the bracket 120 slides along its length in the inner cavity of the housing 110, it will not interfere with the button. When disassembling, the bracket 120 can slide out from the opening at the first end 111 of the housing 110. At this time, the battery body 150 can be removed from the bracket 120 for replacement. This allows the bracket 120 to be easily removed from the opening at the first end 111 of the housing 110 without interfering with the button, realizing the disassembly and separation of the battery from the housing 110 and the button.

[0048] In some embodiments, such as Figure 3 and Figure 8 As shown, the button includes a button body 130. A limit buckle 132 is provided on the side of the button body 130 facing the sleeve 160. The limit buckle 132 can abut against the inner wall of the outer shell 110 around the button hole 113 and form a limiting structure to prevent the button from coming out of the button hole 113.

[0049] Specifically, the limiting buckle 132 is J-shaped. A limiting buckle 132 is provided at the end of the button body 130 near the first end 111 of the outer shell 110 and at the end near the second end 112 of the outer shell 110. The top of the J-shaped limiting buckle 132 is connected to the side of the button body 130 facing the sleeve 160. The free end of the J-shaped limiting buckle 132 near the first end 111 of the outer shell 110 extends toward the first end 111 of the outer shell 110, and the free end of the J-shaped limiting buckle 132 near the second end 112 of the outer shell 110 extends toward the second end 112 of the outer shell 110, so that the width of the button body 130 with the limiting buckle 132 is greater than the width of the button hole 113.

[0050] When the button body 130 is pressed, the button body 130 moves toward the sleeve 160 and drives the limit buckle 132 downward together; when the button body 130 is released, the free end of the limit buckle 132 can abut against the inner wall of the outer shell 110 around the button hole 113 to prevent the button from falling out of the button hole 113.

[0051] In some specific embodiments, such as Figure 2 and Figure 3 As shown, the outer shell 110 around the button hole 113 can be locked in the gap between the button body 130 and the limiting buckle 132, and can limit the displacement of the button relative to the outer shell 110 in the length direction of the outer shell 110.

[0052] In addition to preventing the button body 130 from falling out of the button hole 113 relative to the outer casing 110, it is also necessary to minimize the shaking of the button body 130 within the button hole 113; and since the button body 130 is inserted into the button hole 113, its displacement in the length direction of the outer casing 110, or its displacement perpendicular to the length direction of the outer casing 110, is also important. Figure 3 The left and right directions are also restricted by the outer shell 110 around the button hole 113, which is locked in the gap between the button body 130 and the limiting buckle 132. In this way, the displacement in all directions is restricted, thereby ensuring that the button body 130 can be effectively positioned between the outer shell 110 and the sleeve 160 and is not easy to fall off.

[0053] In some specific embodiments, the limiting structure is a directional limiting structure that only restricts the button from disengaging from the button hole 113 radially outward along the outer shell 110, but does not restrict the button from disengaging from the button hole 113 radially inward. This allows the button to lose support after the bracket 120 is removed from the outer shell 110, falling from the button hole 113 into the inner cavity of the outer shell 110 and being removed from the opening at the first end 111 of the outer shell 110. Because the power supply device 100 uses a detachable button, which is a high-frequency, easily damaged component, the detachable design avoids the scrapping of the entire device due to button failure, conforming to the concept of a circular economy. When a button is damaged, only the button module needs to be replaced, not the entire power supply device 100, reducing material waste, extending the product's lifespan, and lowering operating costs.

[0054] In some embodiments, such as Figures 1-4 as well as Figure 7As shown, the power supply device 100 also includes a sleeve 160, which is also a cylindrical structure. The sleeve 160 has a fifth end 161 and a sixth end 162 arranged opposite each other in the length direction. The sleeve 160 is disposed between the outer shell 110 and the bracket 120. Specifically, the sleeve 160 is sleeved on the outer periphery of the bracket 120, and the outer shell 110 is sleeved on the outer periphery of the sleeve 160, forming a stacked structure. The fifth end 161 of the sleeve 160 is close to the first end 111 of the outer shell 110, and the sixth end 162 of the sleeve 160 is close to the second end 112 of the outer shell 110. The sleeve 160 and the outer shell 110 are fixedly connected by a connector, and the button is disposed between the outer shell 110 and the sleeve 160.

[0055] Since the bracket 120 no longer interferes with the button after sliding out of the opening at the first end 111 of the outer shell 110, the button, having lost its support, will fall into the inner cavity of the outer shell 110 and then slide out from the opening at the first end 111 of the outer shell 110. Because the button body 130 and the elastic element 140 are very small, they are not easy to retrieve after falling. In this embodiment, a sleeve 160 is added, with the bracket 120 disposed inside the sleeve 160 and the button disposed between the outer shell 110 and the sleeve 160. In this way, when the bracket 120 is pulled out relative to the sleeve 160, the button is still limited between the outer shell 110 and the sleeve 160, and will not fall into the inner cavity of the outer shell 110, nor will it slide out from the opening at the first end 111 of the outer shell 110 and be lost.

[0056] In some embodiments, such as Figure 3 and Figure 7 As shown, the sleeve 160 has a switch hole 165, and the power switch 125 on the bracket 120 is located within the radial projection contour of the switch hole 165; the button includes a button body 130 and an elastic element 140 connected to each other. The button body 130 passes through the button hole 113, and the elastic element 140 is located between the button body 130 and the power switch 125 and can provide the button body 130 with a spring force that moves radially away from the bracket 120; the button body 130 can be made of a rigid material, and the elastic element 140 can be made of a soft and elastic material such as silicone.

[0057] Thus, when the button body 130 is pressed toward the bracket 120, the button body 130 drives the elastic element 140 to move toward the power switch 125, and the force is transmitted to the power switch 125 through the elastic element 140 to turn the power supply device 100 on / off; after the button body 130 is released, the elastic force of the elastic element 140 will cause the button body 130 to spring back to the initial position.

[0058] In some embodiments, such as Figure 3 , Figure 6 and Figure 7As shown, the sleeve 160 is provided with a clearance hole, and the bracket 120 is provided with a clearance recess corresponding to the clearance hole. When the button body 130 moves toward the sleeve 160, the limiting buckle 132 passes through the clearance hole and approaches the clearance recess.

[0059] When the button moves radially along the housing 110, that is, when the button body 130 is pressed and moves toward the sleeve 160, the clearance holes and clearance recesses can provide sufficient displacement space for the limiting latches 132; specifically, the clearance holes include a first clearance hole 163 and a second clearance hole 164 corresponding to the two J-shaped limiting latches 132; the clearance recesses include a first clearance recess 123 and a second clearance recess 124 corresponding to the two J-shaped limiting latches 132; a J-shaped The limiting buckle 132 passes through the first clearance hole 163 and the first clearance recess 123 in sequence, and abuts against the bottom of the first clearance recess 123. Another J-shaped limiting buckle 132 passes through the second clearance hole 164 and the second clearance recess 124 in sequence, and abuts against the bottom of the second clearance recess 124. The button body 130 and the limiting buckle 132 both reach the end of the radial movement stroke. At this time, the power switch 125 is also pressed, thereby realizing that the power switch 125 is pressed and turned on.

[0060] In some embodiments, such as Figure 9 As shown, the elastic element 140 includes a sheet-like main body. The middle of the main body is recessed downward to form a U-shaped pressing groove 141. A pressing protrusion 131 is provided on the side of the button body 130 facing the sleeve 160. The pressing protrusion 131 is inserted into the pressing groove 141 on the main body to realize the connection between the button body 130 and the pressing groove 141. The pressing groove 141 of the main body abuts against the power switch 125. When the button body 130 is pressed, it sequentially drives the pressing protrusion 131 and the pressing groove 141 downward and presses them down. The power switch 125 has a spring-loaded support 142 circumferentially connected to its main body. One end of the spring-loaded support 142 is connected to the main body, and the other end abuts against the outer wall of the sleeve 160. When the button body 130 is pressed down, the distance between the main body of the elastic element 140 and the outer wall of the sleeve 160 is compressed, and the spring-loaded support 142 is also compressed. When the button body 130 is released, the spring-loaded support 142 returns to its original state and drives the main body of the elastic element 140 away from the outer wall of the sleeve 160, thereby driving the button body 130 to reset.

[0061] In some embodiments, such as Figure 1 , Figure 2 , Figure 4 and Figure 10 As shown, the power supply device 100 also includes an end connector 170, and the second end 112 of the housing 110, the fourth end 122 of the bracket 120 and the sixth end 162 of the sleeve 160 are connected and cooperated through the end connector 170.

[0062] By providing an end connector 170 at the same end of the housing 110, bracket 120, and sleeve 160, the housing 110, bracket 120, and sleeve 160 can be connected and relatively fixed. When disassembling, the housing 110, bracket 120, and sleeve 160 can be separated simply by removing the end connector 170. Disassembly and assembly are both very simple and convenient.

[0063] In some embodiments, such as Figure 1 , Figure 4 and Figure 11 As shown, it also includes an end cap 180, and an end connector 170 including a first step 171 and a second step 172 disposed on one side of the housing 110 along its length and a third step 173 disposed on the other side of the housing 110 along its length. The second end 112 of the housing 110 abuts against the first step 171 and is interference-fitted with the end connector 170; the sixth end 162 of the sleeve 160 abuts against the second step 172 and is interference-fitted with the end connector 170.

[0064] The end cap 180 is fastened onto the third step 173. The fourth end 122 of the bracket 120 is provided with a screw post 126. The end connector 170 is provided with a first through hole 174. The end cap 180 is provided with a countersunk hole 181. The screw post 126 passes through the first through hole 174 and is threadedly connected to the screw 182 provided in the countersunk hole 181. The end connector 170 is also provided with a second through hole for the charging port to pass through. The end cap 180 is also provided with a corresponding opening. When the end cap 180 is fixed to the screw post 126 by the screw 182, the charging port is flush with the end cap 180, and the charging function can be realized.

[0065] When the battery body 150 needs to be replaced, disassembly can be performed;

[0066] Disassembly process:

[0067] Step 1: Unscrew screw 182 and remove end cap 180;

[0068] Step 2: Since the outer shell 110 and sleeve 160 are interference-fitted with the end connector 170, they can remain relatively fixed. The screw post 126 of the bracket 120 passes through the end connector 170. After the screw 182 is removed, it can be pushed out along the length of the outer shell 110. Therefore, by pressing the two screw posts 126 inward relative to the end connector 170, the bracket 120 can be slid out from the opening at the first end 111 of the outer shell 110. Step 3: The removed bracket 120 is as follows: Figure 6 As shown, the battery body 150 can be removed and replaced, and the PCBA board can also be replaced.

[0069] Installation process after replacement: Simply reverse the disassembly steps.

[0070] In some embodiments, such as Figure 1 , Figure 2 and Figure 6 As shown, the third end 121 of the bracket 120 forms a bracket step 1211, which circumferentially abuts against the inner wall of the outer shell 110, and the fifth end 161 of the sleeve 160 abuts against the step surface of the bracket step 1211.

[0071] The bracket step 1211 of the third end 121 of the bracket 120 can limit the radial displacement of the bracket 120 relative to the outer shell 110 and prevent the bracket 120 from shaking inside the outer shell 110; the step surface of the bracket step 1211 can limit the displacement of the sleeve 160 in the longitudinal direction, that is, prevent the bracket 120 from sliding relative to the sleeve 160.

[0072] In some embodiments, such as Figure 1 and Figure 5 As shown, in order to facilitate the observation of the light-transmitting hole 166 to determine the operating status of the power supply device 100, a viewing window 114 is provided on the outer casing 110, which corresponds to the light-transmitting hole 166 on the sleeve 160; a light-transmitting sheet 190 is installed at the viewing window 114.

[0073] This application also provides an aerosol generating apparatus, such as... Figure 2 and 12 As shown, the device includes an atomizer 200 and the aforementioned power supply device 100. A receiving cavity 115 is formed between the first end 111 of the housing 110 and the third end 121 of the bracket 120. At least a portion of the atomizer 200 is located within the receiving cavity 115 and is electrically connected to the battery body 150.
