[0025] Specifically, Figure 1As shown, the heat dissipation hole 4 is opened on the side of the device body 1 away from the connection port 7 and passes through the side of the device body 1, the slide groove 5 is symmetrically distributed on the outside of the heat dissipation hole 4, the slide plate 6 is symmetrically distributed on the outside of the slide groove 5, the bearing 8 is symmetrically distributed inside the device body 1, and the limit groove 11 is symmetrically distributed on the inner wall of the device body 1 close to the heat dissipation hole 4.
[0026] In the present embodiment: by setting up a device body 1, heat dissipation holes 4 are opened on the inner wall of the device body 1. When the temperature inside the device body 1 reaches the upper limit of the set temperature, the temperature control motor 12 starts to drive the belt 13 to rotate, and the belt 13 drives the screw rod 9 to rotate. The rotation of the screw rod 9 causes the symmetrical moving block 10 to move in the opposite direction and slowly move away. The moving block 10 is fixedly connected to the slide plate 6, driving the slide plate 6 to move in the opposite direction to open the heat dissipation holes 4 for effective heat dissipation. When the temperature drops to the set temperature, the output end of the temperature control motor 12 rotates in the opposite direction to cause the slide plate 6 to slowly approach, thereby blocking the heat dissipation holes 4 to prevent dust from entering.
