DETAILED DESCRIPTION

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Example 1, as Figure 1-4 As shown, the utility model provides a technical solution for a retractable electric control box: it includes a fixed frame 1, the outer surface of the fixed frame 1 is open, and an electric control box body 2 is arranged inside the fixed frame 1. The rear edge of the electric control box body 2 extends to the side of the fixed frame 1, and sliders 5 are fixed at the four corners of the rear side of the electric control box body 2. Guide grooves 4 are provided on the internal top and bottom surfaces of the fixed frame 1 near the edges on both sides, and multiple sliders 5 are correspondingly slidably connected to the inside of the guide grooves 4.

[0025] The effect achieved by the entire embodiment 1 is that a heat dissipation port 3 is opened on the outer surface of the electric control box body 2 and penetrates into the inner cavity 13, and a fan 14 is arranged inside the inner cavity 13. The external air flow can be drawn into the electric control box body 2 by the rotation of the fan 14, and the internal heat is discharged from the heat dissipation port 3. At the same time, a filter 9 is arranged between the inner walls of the pull-out frame 8, so that the air entering the inside of the electric control box body 2 is filtered.

[0026] Example 2, as Figure 1-4 As shown, an inner cavity 13 is opened on the rear side of the electric control box body 2, and multiple heat dissipation outlets 3 that penetrate into the inner cavity 13 are opened at equal distances on the outer surfaces of both sides of the electric control box body 2. A fan 14 is arranged inside the inner cavity 13, and multiple fixing rods 15 are installed on the outer surface of the fan 14. One end of the multiple fixing rods 15 are fixed on the inner wall of the inner cavity 13 respectively. A mounting groove 7 is opened at the top of the electric control box body 2 near the rear edge, and a pull-out frame 8 is arranged inside the mounting groove 7. A filter 9 is arranged between the inner walls of the pull-out frame 8. Multiple guide rods 10 are fixed at equal distances at the bottom edge between the front and rear inner walls of the fixed frame 1. The rear bottom of the electric control box body 2 is slidably connected between the outer surfaces of the multiple guide rods 10. A patch plate 6 is fixed on the outer surfaces of both sides of the fixed frame 1 near the bottom edge. A sponge pad 11 is fixed between the inner walls of the fixed frame 1 near the rear edge, and a filter plate 12 is arranged between the inner walls of the fixed frame 1 at the back of the sponge pad 11.

[0027] The effect achieved by the entire embodiment 2 is that when installing the electric control box body 2, the electric control box body 2 is pushed into the inside of the fixed frame 1, so that the rear side of the electric control box body 2 and one side of the sponge pad 11 fit together, so that the outer surface of the sponge pad 11 and the outer surface of the filter 9 fit together, and the filter 9 is supported by the elastic supporting force of the sponge pad 11 to prevent the filter 9 from loosening when the air flow flows. A filter plate 12 is arranged on the rear side of the fixed frame 1 to perform preliminary filtration of the air. Since the inner cavity 13 and the filter 9 are both arranged on one side of the electric control box body 2, when the electric control box body 2 is pulled out, the dust on the filter 9 cannot contact the electric control box body 2, which can avoid the electric control box body 2 being contaminated by dust when it is pulled out.

[0028] Working principle: When using this device, a heat dissipation port 3 is opened on the outer surface of the electric control box body 2 and penetrates into the inner cavity 13, and a fan 14 is set inside the inner cavity 13. The fan 14 can rotate to draw the external air flow into the electric control box body 2, and discharge the internal heat from the heat dissipation port 3. At the same time, a filter 9 is set between the inner walls of the pull-out frame 8 to filter the air entering the electric control box body 2. When installing the electric control box body 2, push the electric control box body 2 into the fixed frame 1 so that the back side of the electric control box body 2 and the sponge pad 11 are in contact. One side of the sponge pad 11 fits together, so that the outer surface of the sponge pad 11 and the outer surface of the filter 9 fit together, and the filter 9 is supported by the elastic supporting force of the sponge pad 11 to prevent the filter 9 from loosening when the airflow flows. A filter plate 12 is arranged on the rear side of the fixed frame 1 to perform preliminary filtration of the air. Since the inner cavity 13 and the filter 9 are both arranged on one side of the electric control box body 2, the dust on the filter 9 cannot contact the electric control box body 2 when the electric control box body 2 is pulled out, which can avoid the electric control box body 2 being contaminated by dust when it is pulled out.
