[0024] Among them, through the structural design of the vent 2, the push switch 3, the limit seat 4, the transmission part 6, the moving rod 8, and the arc-shaped sealing plate 9, and through the mutual cooperation between the structures, the air cooling function is realized, thereby ensuring that the vent 2 can be opened synchronously with the LED lighting, thereby promoting air flow, helping the internal electrical components to dissipate heat, and avoiding heat residue in the inner cavity of the shell, thereby increasing the service life of the circuit board 14, the substrate 19, and the LED lamp beads 20.

[0025] Positioning seats 10 are fixedly mounted on both sides of the inner wall of the upper shell 1 , and a square hole 11 is opened on one side of the positioning seat 10 .

[0026] The positioning seat 10 and the square hole 11 realize the function of limiting the moving rod 8, thereby ensuring that the moving rod 8 is in linear motion and preventing the moving rod 8 from rotating, thereby ensuring that the arc-shaped sealing plate 9 is accurately opened or closed.

[0027] A first filter screen 12 is fixedly installed inside the vent 2 , and an insulating pad 13 is fixedly installed on the back of the upper shell 1 .

[0028] The positioning seat 10 and the square hole 11 realize the function of limiting the moving rod 8, thereby ensuring that the moving rod 8 is in linear motion and preventing the moving rod 8 from rotating, thereby ensuring that the arc-shaped sealing plate 9 is accurately opened or closed.

[0029] A circuit board 14 is fixedly mounted on the middle portion of the inner wall of the upper housing 1 , and an inserting piece 15 is fixedly mounted on the back side of the circuit board 14 .

[0030] The circuit board 14 is used to cooperate with the contact point 23 to control the switch state of the LED lighting, and the plug 15 is used to connect with the socket to realize the conductive function, so as to provide the LED lamp bead 20 for use.

[0031] A lower shell 16 is fixedly mounted on the bottom of the upper shell 1 . A plurality of heat dissipation holes 17 are provided on both sides of the lower shell 16 . A second filter screen 18 is fixedly mounted on both sides of the inner wall of the lower shell 16 .

[0032] The lower shell 16 is used to isolate the substrate 19 and the LED lamp beads 20 from the external environment, thereby ensuring that the LED lamp beads 20 work in a safe environment.

[0033] A base plate 19 is fixedly mounted in the middle of the inner cavity of the lower shell 16 , a plurality of LED lamp beads 20 are fixedly mounted on the front of the base plate 19 , and a lampshade 21 is fixedly mounted in the middle of the front of the lower shell 16 .

[0034] Among them, the function of diffusing light is realized by the lampshade 21, so that the light emitted by the LED lamp beads 20 can be more evenly distributed in the surrounding environment, avoiding the situation of local overbrightness or overdarkness, thereby improving the uniformity and comfort of the lighting effect.

[0035] A connecting rod 22 is fixedly mounted on the middle part of the back side of the push-type switch 3 , and a contact point 23 is arranged at one end of the connecting rod 22 .

[0037] The working principle and use process of the utility model: when using the device, the shell is fixed in the working area by the insert 15, and the push-type switch 3 is pressed. The push-type switch 3 drives the contact point 23 to move toward the circuit board 14 through the connecting rod 22. While the push-type switch 3 is being pressed, the push-type switch 3 simultaneously drives the limit seat 4 to move. The limit seat 4 pushes the moving rod 8 to both sides through the positioning rod 5 and the transmission member 6. The moving rod 8 drives the arc-shaped sealing plate 9 to move outward through the gap between the filter holes of the first filter screen 12. At this time, the vent 2 is in an open state, and the circuit board 14 is cooled by air flow. When the contact point 23 contacts the circuit board 14, the LED lamp bead 20 generates light, and the light is evenly distributed in the surrounding environment through the lampshade 21. The air flow of the lower shell 16 is ensured through the heat dissipation holes 17, and the heat dissipation of the substrate 19 and the LED lamp bead 20 is ensured through the heat dissipation holes 17. At this time, the push-type switch 3 is in a sinking state. Pressing the push-type switch 3 again turns off the lighting and drives the arc-shaped sealing plate 9 to close the vent 2 at the same time.
