[0040] Reference herein to an "embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute a separate or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0041] The present application embodiment provides a power supply assembly 10, please refer to Figures 1 to 3 The power supply assembly 10 includes a shell 110, a battery component 120 and a circuit board 130. The shell 110 is provided with a mounting groove 1101, and a guide groove 1103 is formed on the side wall 111 of the mounting groove 1101; the battery component 120 includes a battery main body 121 and a pole ear 122 connected to the battery main body 121, and the battery component 120 is installed in the mounting groove 1101; the circuit board 130 is arranged at the notch 1102 of the mounting groove 1101, and the pole ear 122 extends along the guide groove 1103 and is electrically connected to the circuit board 130.

[0042] In one embodiment, the guide structure includes a plurality of limit card points (not shown), the plurality of limit card points protrude from the inner surface of the side wall 111, and the extension direction of the plurality of limit card points and Figure 3 The guide groove 1103 shown is consistent, and the limiting points can be distributed on both sides of the tab 122, thereby constraining the tab 122. The guide structure can also use a limiting structure such as a C-shaped clip, which will not be described in detail here.

[0043] Alternatively, as Figure 4As shown, there can be two tabs 122, both located at one end of the battery body 121. The tabs 122 can include a positive electrode and a negative electrode. The guide groove 1103 can be used to accommodate the tabs 122 and orient the tabs 122 to facilitate automated welding of the tabs 122 to the circuit board 130, thereby improving assembly efficiency. In some other embodiments, there can be multiple tabs 122, and the tabs 122 can be distributed at both ends of the battery body 121.

[0044] Furthermore, the tab 122 includes a first section 1221 and a second section 1222. One end of the first section 1221 is connected to the battery body 121, and the second section 1222 is bent from the end of the first section 1221 away from the battery body 121 and extends along the guide groove 1103 to be electrically connected to the circuit board 130. Specifically, the angle between the first section 1221 and the second section 1222 can be 90 degrees, and the tab 122 can be L-shaped.

[0045] Furthermore, if Figure 5 As shown, the circuit board 130 is provided with a first connection plate 131, and the first connection plate 131 has a first connection groove 1301. The second section 1222 is inserted into the first connection groove 1301 and electrically connected to the first connection plate 131. The first connection groove 1301 can be U-shaped and have a certain depth. The depth of the first connection groove 1301 can be greater than the diameter of the second section 1222. Even if there is a deviation in the bending between the first section 1221 and the second section 1222 of the tab 122, it can ensure that the second section 1222 can be inserted into the first connection groove 1301, thereby achieving automated welding. The material of the first connection plate 131 and the tab 122 can be a metal material such as copper and iron, and the battery body 121 can be a capacitive battery.

[0046] Specifically, if Figure 6 As shown, the number of guide slots 1103 can match the number of tabs 122. The guide slots 1103 can extend from the bottom of the mounting slot 1101 to the notch 1102. The end of the second section 1222 away from the first section 1221 can extend out of the guide slot 1103 and be welded to the first connection plate 131. The coordinated arrangement of the guide slots 1103 and the tabs 122 eliminates the need for wire connections, reduces wire resistance, and simplifies the structure of the power supply assembly 10.

[0047] Alternatively, as Figure 7 and Figure 8As shown, the housing 110 is provided with an external electrode 140, which is at least partially embedded in the housing 110. The external electrode 140 includes a connecting portion 141 and an external portion 142. The external portion 142 is exposed outside the housing 110, and the connecting portion 141 is electrically connected to the circuit board 130. An external power source can be electrically connected to the external portion 142 of the external electrode 140 to charge the battery 120, or directly power the atomizer assembly 20 of the atomizer device.

[0048] Furthermore, the circuit board 130 is provided with a second connecting groove 1302, and a second connecting plate 132 is provided at the bottom of the second connecting groove 1302. The connecting portion 141 is inserted into the second connecting groove 1302 and electrically connected to the second connecting plate 132. The connecting portion 141 can be welded together with the second connecting plate 132.

[0049] Furthermore, the external electrode 140 also includes a fixing portion 143, the connecting portion 141 is connected to one end of the fixing portion 143, a turning portion 144 is connected between the other end of the fixing portion 143 and the external portion 142, the side wall 111 includes a first side wall 1111 and a second side wall 1112 arranged opposite to each other, the guide groove 1103 is located on the first side wall 1111, and the fixing portion 143 is embedded in the second side wall 1112.

[0050] Specifically, the connecting portion 141 of the external electrode 140 can protrude from the notch 1102, the external electrode 140 can be integrally formed with the shell 110, and the length of the connecting portion 141 can be flexibly adjusted to match the position of the circuit board 130. The setting of the fixing portion 143 embedded in the shell 110 cancels the turning electrode. The design of inserting the turning electrode into the shell 110 has the risk of air leakage, the suction experience is not good, and the assembly position of the turning electrode must be determined according to the position of the circuit board 130. In some cases, due to space limitations and internal device limitations, the design requirements cannot be met, which is very inflexible and difficult to automate. The integral molding design of the external electrode 140 and the shell 110 makes the connection between the external electrode 140 and the shell 110 tighter, and effectively prevents air leakage caused by the external electrode 140 while meeting the design requirements. At the same time, the connecting portion 141 can be inserted into the second connecting groove 1302, and the matching design of the second connecting plate 132 and the external electrode 140 can facilitate welding to achieve automated assembly.

[0051] Furthermore, the surface of the external portion 142 and the surface of the fixing portion 143 of the external electrode 140 may be parallel to each other, and the surface of the turning portion 144 may be perpendicular to the surface of the external portion 142 and the surface of the fixing portion 143 .

[0052] Alternatively, as Figure 6As shown, a positioning member 112 is provided in the installation groove 1101 , and the positioning member 112 is formed with a positioning groove 1104 . The shape of the positioning groove 1104 matches the shape of the battery body 121 , and the positioning groove 1104 is used to position the battery body 121 .

[0053] Furthermore, the positioning member 112 can be connected to the side wall 111 and located between the first side wall 1111 and the second side wall 1112. The positioning member 112 can be a sheet-like structure and its shape can be U-shaped. The number of positioning members 112 can be one or more. Specifically, the number of positioning members 112 can be two, and the two positioning members 112 are respectively located at both ends of the battery body 121 to position the battery body 121.

[0054] Optionally, please also refer to Figure 9 and Figure 10 An air inlet groove 1105 is provided on the side of the shell 110 away from the circuit board 130, and a first air inlet hole 1106 and a second air inlet hole 1107 are provided in the air inlet groove 1105. The aperture of the first air inlet hole 1106 is larger than the aperture of the second air inlet hole 1107. The first air inlet hole 1106 and the second air inlet hole 1107 are both connected to the mounting groove 1101. A sliding member 170 is provided in the air inlet groove 1105, and the sliding member 170 is slidably connected to the shell 110. The sliding member 170 is used to switch and block the first air inlet hole 1106 or the second air inlet hole 1107.

[0055] Furthermore, a limiting hole 1108 is provided between the first air inlet hole 1106 and the second air inlet hole 1107. The sliding member 170 includes a blocking portion 171 and a limiting portion 172 connected to the blocking portion 171 on the side close to the limiting hole 1108. The limiting portion 172 is engaged with the limiting hole 1108, and the limiting portion 172 can slide along the length direction of the limiting hole 1108. The limiting portion 172 can slide between the first air inlet hole 1106 and the second air inlet hole 1107, so that the blocking portion 171 can block the first air inlet hole 1106 or the second air inlet hole 1107. When the blocking portion 171 blocks the first air inlet hole 1106, external air can enter the mounting groove 1101 through the second air inlet hole 1107. When the blocking portion 171 blocks the second air inlet hole 1107, external air can enter the mounting groove 1101 through the first air inlet hole 1106. By switching between different air inlet apertures, airflow regulation is achieved, thereby adjusting the puffing feel of the atomizer. Specifically, the number of the limiting portion 172 and the limiting hole 1108 can both be two.

[0056] The present application also provides an atomizing device, such as Figure 11 and Figure 12As shown, the atomizing device includes the power supply assembly 10 of the above embodiment, and the atomizing device also includes an atomizing assembly 20, which is electrically connected to the power supply assembly 10. The atomizing assembly 20 can use the electrical energy provided by the power supply assembly 10 to heat the atomizing substrate, forming an aerosol in the atomizing channel 201 for use by the user.

[0057] Optionally, please also refer to Figure 1 、 Figure 7 and Figure 13 As shown, the circuit board 130 is provided with a first through hole 1303, and an airflow sensor 133 is provided at the end of the first through hole 1303 facing away from the battery body 121. A liquid absorbent member 150 is provided between the circuit board 130 and the battery body 121, and a partition 160 is provided between the liquid absorbent member 150 and the first through hole 1303. A guide channel 1601 is formed between the partition 160 and the circuit board 130, and an air guide gap 1304 is formed between the circuit board 130 and the side wall 111. The circuit board 130 is provided with a second through hole 1305, and the second through hole 1305 is connected to the mounting groove 1101 through the air guide gap 1304, and the first through hole 1303 is connected to the second through hole 1305 through the guide channel 1601.

[0058] Specifically, the area of ​​the circuit board 130 is smaller than the area of ​​the notch 1102 , so that an air-guiding gap 1304 is formed between the circuit board 130 and the side wall 111 .

[0059] After external air enters mounting slot 1101 through first air inlet 1106 or second air inlet 1107, it can flow through air guide gap 1304 to the side of circuit board 130 facing away from mounting slot 1101, enter guide channel 1601 through second through-hole 1305, and then pass through first through-hole 1303 along guide channel 1601 to reach airflow sensor 133. This isolates airflow sensor 133 from liquid wicking element 150, preventing liquid in liquid wicking element 150 from flowing through first through-hole 1303 into airflow sensor 133 and damaging it. Furthermore, the air intake path of airflow sensor 133 can be lengthened, preventing aerosol from diffusing into spaces such as mounting slot 1101 and entering airflow sensor 133 when a user blows backwards, effectively preventing erroneous activation of airflow sensor 133.

[0060] Furthermore, the airflow sensor 133 may be a microphone, and the airflow sensor 133 may control the power supply state of the power supply assembly 10 to the atomizer assembly 20 according to the gas flow state. The liquid absorbing member 150 may be made of a material with an adsorption function. Specifically, the liquid absorbing member 150 may be condensation cotton, which can absorb condensation water that slides off the atomizer assembly 20 to prevent damage to the battery assembly 120.

[0061] Alternatively, as Figures 13 to 15As shown, a bracket 210 is provided on the side of the circuit board 130 away from the battery body 121 . The bracket 210 includes a first end 211 and a second end 212 arranged in opposite directions. The first end 211 is arranged close to the circuit board 130 , and the second end 212 is arranged away from the circuit board 130 . The first end portion 211 is provided with a first groove 2101, in which the airflow sensor 133 is located. The second end portion 212 is provided with a second groove 2102. A first connecting hole 2104 is provided at the bottom of the second groove 2102, connecting the first groove 2101 and the second groove 2102. The second end portion 212 is also provided with a third groove 2103, connecting the second groove 2102. The circuit board 130 is provided with a third through hole 1306. A second connecting hole 2105 is provided at the bottom of the third groove 2103, connecting the third groove 2103 and the third through hole 1306. The end of the third through hole 1306 facing away from the bracket 210 is provided with a liquid absorbing member 150. The position of the atomizing channel 201 of the atomizing assembly 20 corresponds to the position of the third through hole 1306, and the atomizing channel 201 is connected to the third groove 2103. Condensed water flowing back from the atomizing channel 201 can flow through the second connecting hole 2105 and the third through hole 1306 to be absorbed by the liquid absorbing member 150.

[0062] Specifically, a protrusion 2111 may be provided on a side of the first end portion 211 facing the circuit board 130 , the second communication hole 2105 may be opened on the protrusion 2111 , and the protrusion 2111 may be inserted into the third through hole 1306 .

[0063] Furthermore, a third connecting hole 2106 is provided at one end of the third groove 2103 away from the second connecting hole 2105 , and a fourth groove 1307 is provided on the circuit board 130 . The third groove 2103 is connected to the mounting groove 1101 through the third connecting hole 2106 and the fourth groove 1307 .

[0064] The design of the bracket 210 allows the first groove 2101, which houses the airflow sensor 133, to communicate with the atomization channel 201 through the second groove 2102 and the third groove 2103. When the user uses the atomization device, low air pressure is generated in the atomization channel 201. After external air enters the mounting groove 1101 through the first air inlet hole 1106 or the second air inlet hole 1107, a portion of the gas can flow through the fourth groove 1307 and the third communicating hole 2106 into the third groove 2103, and then flow along the third groove 2103 into the atomization channel 201. Another portion of the gas can pass through the air guide gap 1304 and the second through hole 1305 into the guide channel 1601, and then pass through the first through hole 1303 along the guide channel 1601 to be sensed by the airflow sensor 133.
