The heat dissipation cavity 207 communicates with the heat dissipation hole 202 through the inside of the housing 101.

[0024] Specifically, the inner wall of the rotating ring 103 is fixedly connected with a plurality of limiting blocks 305, and the fixing block 107 is provided with a plurality of first sliding grooves 204. Each first sliding groove 204 is slidably connected with a first limiting slider 206. A first spring 205 is provided in the first sliding groove 204. The two ends of the first spring 205 are respectively fixedly connected to the inner wall of the first sliding groove 204 and the first limiting slider 206. Each first limiting slider 206 corresponds one-to-one with each limiting block 305 and each first limiting slider 206 corresponds one-to-one with each heat dissipation cavity 207.

[0025] Specifically, the fixing block 107 is provided with a plurality of second sliding grooves 209, and a second limiting slider 301 is slidably connected in each second sliding groove 209. Each second limiting slider 301 corresponds one-to-one with each first limiting slider 206. A second spring 303 is provided in the second sliding groove 209. The two ends of the second spring 303 are respectively fixedly connected to the inner wall of the second sliding groove 209 and the second limiting slider 301.

[0026] Specifically, the upper surface of the panel 104 is provided with a plurality of heat dissipation grooves 306, each of which corresponds one-to-one with each heat dissipation hole 202.

[0027] Working principle:

[0028] When the device wirelessly charges the electrical equipment, the rotating ring 103 can be rotated counterclockwise. At this time, the rotating ring 103 rotates counterclockwise along the internal fixed block 107. As the rotating ring 103 rotates, the first limiting slider 206 unfolds from the fixed block 107 under the action of the first spring 205. At the same time, the second limiting slider 301 in the fixed block 107 abuts against the first limiting slider 206 under the action of the second spring 303. At this time, the dust removal chamber 208 closes. As the rotating ring 103 continues to rotate, the limiting block 305 fixedly connected to the inner wall of the rotating ring 103 abuts against the first limiting slider 206. At this time, the rotation stops, the first limiting slider 206 in the fixed block 107 unfolds, and the heat dissipation chamber 207 opens. At this time, the gas enters the heat dissipation groove 306 through the pump fan 105, air inlet 304, air inlet chamber 108, heat dissipation chamber 207, and heat dissipation hole 202. The heat dissipation groove 306 provides air cooling for the contact surface between the electrical equipment and the panel 104.

[0029] When dust removal is required inside the device, the power supply inside the housing 101 is turned on, and the rotating ring 103 is rotated clockwise. Under the action of the limiting block 305 on the inner wall of the rotating ring 103, the first limiting slider 206 is pressed, that is, the first limiting slider 206 slides into the fixed block 107. At this time, the first spring 205 is compressed. As the first limiting slider 206 slides into the fixed block 107, the heat dissipation cavity 207 is closed. At the same time, as the first limiting slider 206 slides into the fixed block 107, the second limiting slider 301, which corresponds to it, is squeezed and slides downward. At this time, the dust removal hole 302 provided on the second limiting slider 301 is connected to the dust removal cavity 208. At this time, the gas is discharged through the pump fan 105, the air inlet 304, the air inlet cavity 108, the dust removal cavity 208, the dust removal hole 302, and the dust discharge hole 106, and the dust accumulated on the dust filter 109 is discharged from the equipment along the dust discharge hole 106, thus achieving the effect of internal dust removal.
