When installing the filter plate 14, align the collar 16 with the fixing column 11. When pressing the fixing column 11, the limit block 19 will be squeezed by the fixing block 13, and the first spring 17 will contract.

At this time, the universal wheel 23 replaces the inverter box 1 to contact the ground. When the inverter box 1 is pushed, the universal wheel 23 rotates, and the equipment can be moved. By setting the universal wheel 23 and the threaded rod 21, when the staff needs to move the equipment, the time-consuming and labor-consuming manual carrying of the staff is reduced, which is convenient for the staff to move the equipment, reduces the difficulty of the staff to move the equipment, and increases the practicality and convenience of the equipment.

[0028] Further, such as Figure 1 and Figure 4 As shown, the outer wall of the inverter box 1 is fixedly connected to a pair of second support plates 3; the inner wall of the second support plate 3 is in sliding contact with a plurality of slide bars 31; the outer wall of the slide bar 31 is fixedly connected to a brush plate 32; the bottom of the outer wall of the brush plate 32 is fixedly connected to a plurality of bristles 33; the outer wall of the slide bar 31 is fixedly connected to a limit plate 34; the limit plate 34 is in contact with the second support plate 3; the bristles 33 are in contact with the filter plate 14.

Through the provided bristles 33, the dust impurities adsorbed on the side wall of the filter plate 14 can be cleaned out of the surface of the filter plate 14, reducing the frequency of the staff replacing the filter plate 14, increasing the use time of the filter plate 14, reducing the situation that the air intake of the equipment is affected by excessive dust accumulation, and increasing the stability of the equipment.

When removing the equipment, the staff will press the collar 16, and the contact plate 42 will squeeze the second spring 41. When the pressure on the collar 16 is released, the second spring 41 will form a thrust on the contact plate 42, so that the collar 16 is subjected to a force to break away from the outside. The second spring 41 is provided to facilitate the staff to remove the equipment, reduce the difficulty of the staff to remove the equipment, and facilitate the staff to use and maintain the equipment.

[0030] Further, such as Figure 1 and Figure 5 As shown, the outer wall of the inverter box 1 is fixed with a sealing strip 5; the sealing strip 5 is in contact with the filter plate 14; the sealing strip 5 is made of rubber; and the sealing strip 5 does not contact the fixing column 11.

When the device is working, the fan inside the inverter housing 1 will rotate, and the air will flow to the air outlet through the filter plate 14. At this time, the valves 6 will be sucked open by the internal pressure, and the air can flow normally. When the device is notified to work, the valves 6 will return to their original shape. At this time, the inside of the inverter housing 1 is in a relatively sealed space. The valves 6 are arranged to reduce the probability of air flowing into the inside of the inverter housing 1 when the filter plate 14 is replaced and the fan is working, and reduce the probability of dust and impurities directly entering the inside of the device.

[0032] Further, such as Figure 4 As shown, a plurality of balls 7 are arranged on the inner side wall of the slider 12; the balls 7 rotate on the side wall of the slider 12; the balls 7 cannot be separated from the slider 12; the balls 7 are in contact with the fixed column 11. When the device is working, the slider 12 will make sliding contact with the fixed column 11, and the balls 7 will make contact with the fixed column 11 before the slider 12, turning the sliding contact between the slider 12 and the fixed column 11 into rolling contact.

[0033] Working principle: The filter plate 14 is arranged at the position of the air inlet of the inverter case 1. The filter plate 14 filters the air entering the inverter case 1 and intercepts dust and impurities on the side wall of the filter plate 14. When installing the filter plate 14, align the collar 16 with the fixing column 11. When pressing the fixing column 11, the limit block 19 will be squeezed by the fixing block 13, and the first spring 17 will contract. When the filter plate 14 contacts the fixing column 11, the limit block 19 will be located below the fixing block 13. At this time, the first spring 17 pushes the limit block 19 to move toward the fixing block 13, and the filter plate 14 is fixed to the side wall of the inverter case 1. When removing the filter plate 14, unscrew the bolts between the connecting column 15 and the collar 16, press the collar 16, so that the limit block 19 can continue to move until The limit block 19 is below the slider 12, the limit block 19 is lifted, and the slider 12 moves with it until the limit block 19 is separated from the slider 12 and the fixing block 13. The filter plate 14 can be stably and quickly installed by setting the slider 12 and the fixing block 13, which reduces the difficulty of the staff in installing the equipment and reduces the situation that the filter plate 14 is separated from the equipment due to collision problems, reduces the probability of dust entering the inside of the equipment, and increases the practicality and stability of the equipment. The threaded rod 21 is rotated to move the first support plate 22 until the universal wheel 23 contacts the ground, and continues to rotate until the inverter box 1 is separated from the ground. At this time, the universal wheel 23 replaces the inverter box 1 to contact the ground. When the inverter box 1 is pushed, the universal wheel 23 rotates, and the equipment can be moved. The universal wheels 23 and the threaded rods 21 are arranged so that when the staff need to move the equipment, the time-consuming and labor-intensive manual carrying of the staff is reduced, and the staff is convenient for moving the equipment, and the difficulty of the staff moving the equipment is reduced, thereby increasing the practicality and convenience of the equipment. When the equipment stops working, dust will gather at the position of the filter plate 14 near the air inlet, and the sliding rod 31 is pushed to make the bristles 33 rub the filter plate 14, and the bristles 33 clean the dust on the side wall of the filter plate 14. The dust and impurities adsorbed on the side wall of the filter plate 14 can be cleaned off the surface of the filter plate 14 through the arranged bristles 33, thereby reducing the frequency of the staff replacing the filter plate 14, increasing the use time of the filter plate 14, and reducing the impact on the air intake of the equipment due to excessive dust accumulation. In order to increase the stability of the equipment, when removing the equipment, the staff will press the collar 16, and the contact plate 42 will squeeze the second spring 41. When the pressure on the collar 16 is released, the second spring 41 will form a thrust on the contact plate 42, so that the collar 16 is subjected to a force to separate outward. The second spring 41 is provided to facilitate the staff to remove the equipment, reduce the difficulty of the staff to remove the equipment, and facilitate the staff to use and maintain the equipment. When the equipment is working, the filter plate 14 will fit with the inverter box 1, and the sealing strip 5 is provided around the filter plate 14 to compensate for the periphery of the filter plate 14. The sealing strip 5 is provided to reduce the probability of air directly bypassing the filter plate 14 and entering the inside of the inverter box 1, thereby increasing the air tightness of the equipment.When the device is working, the fan inside the inverter case 1 will rotate, and the air will flow to the air outlet through the filter plate 14. At this time, the valve 6 will be sucked open by the internal pressure, and the air can flow normally. When the device is notified to work, the valve 6 will return to its original shape. At this time, the inside of the inverter case 1 is in a relatively sealed space. The valve 6 is set to reduce the probability of air flowing into the inside of the inverter case 1 when the filter plate 14 is replaced and the fan is working, and the probability of dust and impurities directly entering the inside of the device is reduced. When the device is working, the slider 12 will slide with the fixed column 11, and the ball 7 will contact the fixed column 11 before the slider 12, and the sliding contact between the slider 12 and the fixed column 11 will be changed into rolling contact. The set ball 7 can reduce the wear between the fixed column 11 and the slider 12, increase the smoothness of the slider 12 when moving, and reduce the probability of equipment failure.
