[0025] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or there can be one or more centered elements therebetween. When an element is described as "connected to" another element, it can be directly connected to the other element, or there can be one or more centered elements therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are for illustrative purposes only.

[0026] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this utility model belongs. The terms used in this specification and in the description of this utility model are only for the purpose of describing specific embodiments and are not intended to limit the utility model. The term "and / or" used in this specification includes any and all combinations of one or more of the relevant listed items.

[0027] In current electronic atomization devices, there are two main types of modules that provide power. One is a disposable, non-rechargeable power supply module; the other is a rechargeable power supply module. The former easily leads to waste of resources and environmental pollution, and when the power is exhausted, the electronic atomization device can only be replaced. In the latter, the energy storage capacity of the power supply module decreases with the number of uses, and in actual use, there will be situations where timely charging is required. The relationship between charging efficiency and heat loss means that when the user needs to use the electronic atomization device, if the power supply module is exhausted, they need to wait for the power supply module to recharge at an external power source before continuing to use it, which affects the user experience.

[0028] Based on the above situation, the present application provides an electronic atomization device 1, including a power supply device 1000. In addition, the electronic atomization device 1 also includes an atomization component (also known as an atomizer, a cigarette cartridge, etc.), which is installed on the power supply device 1000, and the atomization component is detachably installed on the power supply device 1000. The power supply device 1000 is electrically connected to the atomization component so that the power supply device 1000 is used to power the atomization component to generate an aerosol. The electronic atomization device 1 provided in this application provides the following solutions to the above technical problems.

[0029] See also Figure 1 and Figure 2 The power supply device 1000 includes a bracket 100 , a circuit module 200 and a battery cell assembly 300 .

[0030] In some embodiments, see Figures 1 to 3The bracket 100 is provided with a first accommodating cavity 110. The circuit module 200 includes a circuit board 210, a first wire 220, and a first connecting terminal 230. The first connecting terminal 230 is electrically connected to the circuit board 210 via the first wire 220. The battery cell assembly 300 is removably installed in the first accommodating cavity 110; the battery cell assembly 300 includes a battery cell 310, a second wire 320, and a second connecting terminal 330. The second connecting terminal 330 is electrically connected to the battery cell 310 via the second wire 320, and the second connecting terminal 330 is detachably connected to the first connecting terminal 230.

[0031] Through the above structure, when the battery cell 310 of the power supply device 1000 is exhausted or fails, it is only necessary to disconnect the electrical connection between the first connection terminal 230 and the second connection terminal 330, and then remove the battery cell 310 from the first accommodating cavity 110 for replacement. The only components to be replaced are the battery cell 310 and the second connection terminal 330, thereby reducing costs.

[0032] It's worth noting that the first accommodating cavity 110 is provided with openings of varying sizes that extend through it. The larger opening allows the battery cell 310 to be placed in or removed from the first accommodating cavity 110, while the smaller opening blocks the movement of the battery cell 310, preventing it from escaping through the other openings while inside the first accommodating cavity 110. The through-opening design of the first accommodating cavity 110 effectively reduces the amount of coverage of the bracket 100 on the surface of the battery cell 310, thereby improving heat dissipation efficiency when the battery cell 310 is operating.

[0033] In some embodiments, see Figures 2 to 3 , the first connecting terminal 230 or the second connecting terminal 330 includes a male plug-in terminal or a female plug-in terminal. That is, one of the first connecting terminal 230 and the second connecting terminal 330 is a male plug-in terminal, and the other is a female plug-in terminal, thereby completing the mutual adaptation between the connectors, and can improve the connection stability, and facilitate installation or disassembly. It should still be noted that the first wire 220 and the second wire 320 are flexible parts, so that when the battery cell 310 is installed, the first connecting terminal 230 or the second connecting terminal 330 can be plugged in outside the first accommodating cavity 110, and by bending or folding the first wire 220 and the second wire 320, there will be no interference with the battery cell 310 being accommodated in the first accommodating cavity 110.

[0034] In some embodiments, see Figures 2 to 3After the first connection terminal 230 and the second connection terminal 330 are connected, they are arranged between the battery cell assembly 300 and the circuit module 200. That is, the first connection terminal 230 and the second connection terminal 330 are respectively located at positions where the battery cell assembly 300 and the circuit module 200 are close to each other. Specifically, the first connection terminal 230 and the second connection terminal 330 are arranged between the battery cell 310 and the circuit board 210. On the one hand, it facilitates circuit planning and internal structure planning, thereby making full use of the internal space of the first accommodating cavity 110, making it easy to remove the battery cell 310 without being affected by the entanglement of the first wire 220 and / or the second wire 320; on the other hand, it reduces the length of the first wire 220 and the second wire 320, thereby improving the stability of the electrical connection.

[0035] In some embodiments, see Figure 3 The bracket 100 is further provided with a second accommodating cavity 120, in which the circuit board 210 is retained. It is understood that the first accommodating cavity 110 and the second accommodating cavity 120 are separated so that the battery cell 310 does not affect the installation stability of the circuit board 210 when it is installed in or removed from the first accommodating cavity 110. The provision of the second accommodating cavity 120 can effectively install and fix the circuit board 210, thereby maintaining the circuit board 210 in the second accommodating cavity 120. It is understood that the board surface of the circuit board 210 is arranged along the arrangement direction of the first accommodating cavity 110 and the second accommodating cavity 120, thereby fully utilizing the internal space of the second accommodating cavity 120 and improving the space utilization rate of the second accommodating cavity 120.

[0036] In some embodiments, see Figure 4 and Figure 5 A first latch 130 is further provided in the second accommodating cavity 120. The first latch 130 engages with the mounting surface of the circuit board 210 to retain the circuit board 210 in the second accommodating cavity 120. It is worth noting that the first latch 130 secures the circuit board 210 by clamping and holding the circuit board 210 in place along both mounting surfaces. The first latch 130 may be a protrusion and a hook disposed opposite each other, or may be another latching structure that is directly engaged with the circuit board 210.

[0037] In some embodiments, see Figure 4 and Figure 5 The circuit board 210 has a first mounting surface 211 and a second mounting surface 212 opposite to each other. The first mounting surface 211 and the second mounting surface 212 are respectively used for mounting different electronic components.

[0038] In some embodiments, see Figure 4The power supply device 1000 further includes a first cover plate 400, which is detachably connected to the bracket 100 and covers the first mounting surface 211. This fully utilizes the two mounting surfaces of the circuit board 210, thereby optimizing the distribution of components on the surface of the circuit board 210. Furthermore, the first cover plate 400 protects the first mounting surface 211. Furthermore, the detachable connection between the first cover plate 400 and the bracket 100 facilitates direct maintenance of the first mounting surface 211 of the circuit board 210 after removing the first cover plate 400, thereby improving the maintainability of the circuit board 210 and extending the service life of the power supply device 1000.

[0039] In some embodiments, see Figure 5 , combined with the first mounting surface 211 and second mounting surface 212 of the circuit board 210. The power supply device 1000 also includes a microphone 500 and a second cover 600; the microphone 500 is mounted on the second mounting surface 212, and the second cover 600 is disposed over the second mounting surface 212. It will be understood that the microphone 500 is used to activate the circuit board 210 and thereby operate it when the circuit board 210 and the battery cells 310 are electrically connected. The provision of the second cover 600 not only protects the microphone 500 but also allows for direct maintenance of the microphone 500 after removal, thereby extending the service life of the power supply device 1000.

[0040] Combining the above embodiments, we can get Figure 4 and Figure 5 The first cover 400, second cover 600, and bracket 100 together enclose a second accommodating cavity 120 for accommodating the circuit board 210 and microphone 500, thereby accommodating, mounting, and protecting the circuit board 210. The detachable design effectively improves the maintainability of the power supply device 1000. In terms of appearance, the detachable design allows users to achieve a personalized design by replacing the first and second covers 400, 600 with different colors.

[0041] For the first accommodating cavity 110 and the second accommodating cavity 120, please refer to Figure 3 The first accommodating chamber 110 is located near the bottom of the power supply device 1000, and the second accommodating chamber 120 is located near the top of the power supply device 1000. It should be noted that the top of the power supply device 1000 refers to the portion for plugging in the atomizer assembly. The user can use the power supply device 1000 at the top. Conversely, the portion away from the atomizer assembly is the bottom of the power supply device 1000.

[0042] In some embodiments, see Figure 3The bracket 100 is at least partially disposed within the housing 700 and is detachably connected to the housing 700. The circuit module 200 and the battery cell assembly 300 are disposed within the housing 700. By fitting the housing 700 within the bracket 100, the housing 700 and the bracket 100 together form a first accommodating cavity 110, thereby preventing the battery cell 310 from falling out of the first accommodating cavity 110.

[0043] In some embodiments, see Figure 3 The bracket 100 is also provided with an abutment portion 140, which is located on the side of the first accommodating chamber 110 away from the second accommodating chamber 120. The shell 700 can movably abut the abutment portion 140, and the shell 700 can move between a first preset position and a second preset position relative to the bracket 100. In the first preset position, the shell 700 is sleeved on the bracket 100 and abuts the abutment portion 140; in the second preset position, the shell 700 is detached from the bracket 100 and the shell 700 is separated from the abutment portion 140. An installation cavity 720 is also provided at one end of the shell 700 away from the abutment portion 140. The shell 700 extends beyond the bracket 100 to form an installation cavity 720 for installing the atomizer assembly. That is, the end of the bracket 100 provided with the second accommodating chamber 120 and the shell 700 together form an installation cavity 720 for installing the atomizer assembly.

[0044] To further install the atomizer assembly, please refer to Figure 3 The power supply device 1000 also includes a spring pin 800, which extends toward the mounting cavity 720 and penetrates the bracket 100 to electrically connect to the circuit board 210 within the second accommodating cavity 120. The spring pin 800 not only enables electrical connection between the atomizer assembly and the circuit board 210, but also allows the power supply device 1000 to supply power to the atomizer assembly. Furthermore, the provision of the spring pin 800 facilitates pluggable connection of the atomizer assembly.

[0045] In some embodiments, see Figure 3 The power supply device 1000 also includes a seal 900, which is arranged around the top of the bracket 100 so that the seal 900 can separate the installation cavity 720 from the second accommodating cavity 120, and separate the installation cavity 720 from the first accommodating cavity 110, thereby effectively preventing the liquid in the atomization component from leaking and corroding the circuit board 210 or the battery cell 310.

[0046] In some embodiments, see Figure 3The bracket 100 is further provided with a second latch 150, and the housing 700 is further provided with a latching hole 710. The housing 700 is movable relative to the bracket 100 between a first preset position and a second preset position. In the first preset position, the housing 700 is mounted on the bracket 100, and the second latch 150 is latched in the latching hole 710. In the second preset position, the housing 700 is separated from the bracket 100, and the second latch 150 is disengaged from the latching hole 710. The second latch 150 and the latching hole 710 enable a detachable connection between the housing 700 and the bracket 100, and the latching fit prevents the housing 700 and the bracket 100 from being stably mounted. In the first preset position, the housing 700 and the bracket 100 together enclose the first accommodating cavity 110. In the second preset position, the housing 700 is separated from the bracket 100, opening the first accommodating cavity 110, thereby facilitating electrical connection between the first connecting terminal 230 and the second connecting terminal 330.

[0047] In order to optimize the cooperation between the second fastener 150 and the fastening hole 710, please refer to Figure 3 In some embodiments, the bracket 100 is further provided with a relief slope 160, which is provided on the second latch 150. The relief slope 160 is used to provide a clearance space when the housing 700 moves from the second preset position to the first preset position. It can be understood that the relief slope 160 is inclined so that when the second latch 150 slides into the engaging hole 710, there is no hard abutment, thereby facilitating the second latch 150 to slide into the engaging hole 710. In other words, by providing the abutment portion 140 and / or the second latch 150, the housing and the bracket 100 are facilitated to be removably secured by the latch.

[0048] At least partially different from the above embodiments, the power supply device in some other embodiments includes a housing 700, a bracket and a battery cell assembly.

[0049] In these examples, see Figure 2The housing 700 has a third accommodating cavity 730, and the housing 700 is provided with a snap-fitting hole 710 that connects the third accommodating cavity 730 with the outside of the housing 700. The bracket 100 is removably arranged in the housing 700, and the bracket 100 is provided with a first accommodating cavity 110. The battery cell assembly is installed in the first accommodating cavity 110. Among them, the bracket 100 includes a second fastener 150, at least a portion of the second fastener 150 is located in the snap-fitting hole 710, thereby cooperating with the snap-fitting hole 710 to lock the bracket 100 in the third accommodating cavity 730, and the second fastener 150 is exposed through the snap-fitting hole 710, so as to provide a user with an operation to release the snap-fitting between the second fastener 150 and the snap-fitting hole 710. It is understood that there are two snap-fit ​​holes 710 and two second snap-fit ​​members 150, and the two snap-fit ​​holes 710 are oppositely disposed on two sides of the housing 700, while the two second snap-fit ​​members 150 are oppositely disposed on two sides of the bracket 100, so that the two sides snap-fit ​​together, thereby improving the stability of the snap-fit.

[0050] In other embodiments, see Figure 2 The bracket 100 includes a first support arm 170 and a second support arm 180 spaced apart from each other. The first accommodating cavity 110 is located between the first support arm 170 and the second support arm 180. The second latch 150 is located on the first support arm 170 and / or the second support arm 180, so that the first support arm 170 and / or the second support arm 180 can be deformed under user operation. By providing the deformable first support arm 170 and / or the second support arm 180, the user can press at least one of the first support arm 170 and / or the second support arm 180 on both sides, specifically by pressing the second latch 150 on both sides, so that the second latch 150 and the engaging hole 710 are offset, thereby facilitating the disengagement between the housing 700 and the bracket 100. During installation, the housing 700 can be placed along the bracket 100 and slid relative to it, and the second latching members 150 on both sides can be pressed so that the second latching members 150 can extend into the housing 700 and slide into the latching holes 710, thereby achieving a snap-fit ​​fit. Optionally, the first support arm 170 and / or the second support arm 180 can be made of a plastic, rubber, or other elastic material.

[0051] In conjunction with the above embodiments, the present application provides a power supply device 1000, comprising a bracket 100, a circuit module 200, and a cell assembly 300. The bracket 100 is provided with a first accommodating cavity 110. The circuit module 200 comprises a circuit board 210, a first conductive wire 220, and a first connecting terminal 230, wherein the first connecting terminal 230 is electrically connected to the circuit board 210 via the first conductive wire 220. The cell assembly 300 is removably mounted in the first accommodating cavity 110. The cell assembly 300 comprises a cell 310, a second connecting terminal 330 electrically connected to the cell 310 via a second conductive wire 320, and the second connecting terminal 330 is detachably connected to the first connecting terminal 230. With this structure, if the cell 310 of the power supply device 1000 is depleted or fails, the cell 310 can be removed from the first accommodating cavity 110, and the second connecting terminal 330 can be disconnected from the first connecting terminal 230, allowing replacement of the cell assembly 300. This eliminates the need to discard other electronic components, reducing costs.
