Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Specific examples are given below.

[0024] See also Figures 1-4 The utility model provides a control box structure, including a box body 1; a dustproof box 2 is fixedly connected to the top of the box body 1, and the box body 1 is communicated with the dustproof box 2 so that heat is dissipated through the dustproof box 2. A heat dissipation port 3 is opened on one side of the dustproof box 2, and a dustproof net 62 is provided at the heat dissipation port 3. The dustproof net 62 includes a frame and a net body connected to the inner wall of the frame, and the dustproof net 62 can cover the heat dissipation port 3.

[0025] The control box structure also includes a cleaning mechanism 6 for cleaning the mesh of the dustproof net 62. The cleaning mechanism 6 includes two first cylinders 61. The first cylinders 61 are arranged inside the dustproof box 2. The telescopic rods of the two first cylinders 61 are respectively connected to the left and right ends of the inner surface of the dustproof net 62 frame. When the first cylinders 61 are controlled to move, the dustproof net 62 can be driven away from the heat dissipation port 3. The support frame 63 in the cleaning mechanism 6 is fixedly connected to the upper end of the outer surface of the dustproof net 62 frame. The support frame 63 is in an inverted U shape, that is, the support frame 63 includes a horizontal arm and two vertical arms. The screw rod 64 is rotatably connected between the two vertical arms. One end of the screw rod 64 passes through one of the vertical arms and is fixedly connected to the gear 65. A fixed plate 4 is fixedly connected to the dustproof box 2. The fixed plate 4 is arranged along the moving direction of the dustproof net 62. A rack 5 is provided on the upper surface of the fixed plate 4. The gear 65 can engage with the rack 5. A scraper plate 66 is threadedly connected to the screw rod 64 between the two vertical arms. Therefore, when the screw rod 64 rotates, the scraper plate 66 can move along the screw rod 64.

[0026] During operation, through the setting of the cleaning mechanism 6, the control box can automatically clean the dust net 62 through remote control during use, reducing the frequency of manual cleaning of the dust net 62, that is, when the dust net 62 needs to be cleaned, the first cylinder 61 can be controlled to start to drive the dust net 62 to move. During the movement of the dust net 62, the gear 65 also moves synchronously. During this process, the gear 65 contacts the rack 5, causing the gear 65 to rotate. The rotation of the gear 65 drives the screw rod 64 to rotate, and then the scraper plate 66 moves to scrape off the dust accumulated on the dust net 62, reducing the frequency of manual cleaning by workers.

[0027] Further, such as Figure 4 As shown, a blocking block 7 is fixedly connected to the interior of the dustproof box 2. The left and right ends of the inner surface of the dustproof net 62 frame are fixedly connected to the left and right ends of the sealing plate 8 through connecting blocks. The sealing plate 8 is provided with a through hole for use with the telescopic rod of the first cylinder 61, so that the telescopic rod of the first cylinder 61 can pass through the sealing plate 8 to achieve normal operation. The sealing plate 8 is provided with a fitting groove adapted to the blocking block 7 on a side near the dustproof net 62. During operation, the setting of the blocking block 7 and the sealing plate 8 can block the heat dissipation port 3 during the cleaning process, thereby preventing dust from entering the cleaning process as much as possible. Specifically, when the first cylinder 61 is controlled to operate, the cleaning mechanism 6 can clean the dustproof net 62. At the same time, when the dustproof net 62 moves, it will drive the sealing plate 8 to move, thereby making the blocking block 7 cooperate with the fitting groove in the sealing plate 8. Through the cooperation of the blocking block 7 and the sealing plate 8, the heat dissipation port 3 is blocked.

[0028] Further, such as Figure 1 As shown, the top of the box body 1 is provided with a chute 9, a slider is slidably connected in the chute 9, and the upper end of the slider extends out of the chute 9 and is fixedly connected to a protective plate. During operation, the dustproof net 62 can be shielded by the setting of the protective plate when the control box is not in use.

[0029] Further, such as Figure 1 As shown, the top of the box body 1 is fixedly connected to a second cylinder 10, and the telescopic rod of the second cylinder 10 is fixedly connected to the connecting plate, and the connecting plate is fixedly connected to the protective plate. During operation, the movement of the protective plate can be remotely controlled by the arrangement of the second cylinder 10 and the connecting plate.

[0030] Further, such as Figure 3As shown, the dustproof box 2 is provided with a blowing slot. A plurality of blowing ports 11 are spaced apart at the lower end of the side of the dustproof box 2 where the heat dissipation port 3 is located. These ports are connected to the blowing slot, and the inner wall of the blowing ports 11 is provided with a filter. During operation, the blowing slot and the blowing ports 11 can be provided with an air pump as needed to generate blowing gas and blow it out of the blowing ports 11 to remove the cleaned dust.

[0031] Further, such as Figure 3 As shown, a pressure plate 13 is slidably connected in the blowing groove, and a pressure rod 12 is fixedly connected to one side of the pressure plate 13. One end of the pressure rod 12 passes through the dustproof box 2 and is fixedly connected to the auxiliary block. The auxiliary block is fixedly connected to the bottom of the dustproof net 62 frame. When the dustproof net 62 moves, it can drive the pressure plate 13 to move. The pressure plate 13 squeezes the air in the blowing groove and sprays it out through multiple blowing ports 11 to blow and clean the dust that has fallen from the dustproof net 62.

[0032] Further, such as Figure 2 、 4 As shown, a sealing gasket is provided on the side of the dustproof box 2 that contacts the dustproof net 62 frame, and a sealing gasket is provided on the inner side wall of the fitting groove. During operation, the sealing gasket can improve the sealing performance.

[0033] During the specific working process, when the dust net 62 needs to be cleaned, the first cylinder 61 can be controlled to start to drive the dust net 62 to move, and then the gear 65 can move. During this process, the gear 65 contacts the rack 5, causing the gear 65 to rotate, and the gear 65 drives the screw 64 to rotate, so that the scraper plate 66 can move to scrape off the dust accumulated on the dust net 62, reducing the frequency of manual cleaning by workers.
