Working principle: When using the multi-functional electronic equipment dust removal tool, make a simple understanding of the device.

First, open the box door 25, place the electronic equipment to be dust-removed on the filter plate 24, slightly lift the electronic equipment, and then start the two sets of drive motors 37, the drive motors 37 drive the second pulley 36 to rotate, and the second pulley 36 drives the first pulley 34 to rotate through the belt 35 while rotating, and the first pulley 34 drives the first threaded rod 30 to rotate through the bearing 28 and the rotating shaft 29. Because the slider 31 is threadedly connected to the first threaded rod 30, and slides It is connected in the through slot 27 , so under the rotation of the first threaded rod 30 , the slider 31 drives the push plate 32 to slide in the through slot 27 , so that the electronic device is clamped between the two sets of rotating cylinders 33 .

When removing dust from the electronic equipment, the rotary cylinder 33 can be activated to drive the electronic equipment to rotate slowly, so that there is no dead angle when the electronic equipment is dust-removed, so as to improve the dust-removing effect, close the shutter 5 and the box door 25, start the air compressor 6, The compressor 6 passes the compressed air into the first nozzle 9 through the spring tube 7. When the first nozzle 9 sprays high-pressure gas to clean the electronic equipment, the telescopic rod 11 is activated. The card slot 10 moves back and forth, thereby driving the first nozzle 9 to move back and forth, so that the surface of the electronic device can be uniformly dedusted, thereby facilitating the improvement of the dedusting effect.

Secondly, while removing dust from the surface of the electronic equipment, start the water pump 15, and the water pump 15 transports the water in the water storage bucket 13 to the atomizer 17. After the atomizer 17 is atomized, it is distributed through the shunt pipe 19 to the first The second nozzle 20 sprays mist-like water droplets, suppresses internal dust through water vapor, prevents internal dust from flying, and cleans the surface of electronic equipment at the same time. For electronic equipment that is not waterproof, you can skip this step.

Then, the sewage formed by the combination of water droplets and dust enters the storage box 23 through the filter plate 24. After cleaning the electronic equipment, the box door 25 is opened, and the storage box 23 is pulled out through the slide rails 21 and the slide plates 22 on both sides, so as to facilitate collection. Before removing the sewage, start the servo motor 43, and the servo motor 43 drives the second threaded rod 42 to rotate. Since the inner threaded pipe 41 is connected to the fixed cylinder 38 through the chute 39 and the clamping plate 40, the second threaded rod 42 cannot drive the inner threaded rod 42. The threaded pipe 41 rotates, but the female threaded pipe 41 moves downward in the fixed cylinder 38, so that the end of the female threaded pipe 41 touches the ground, and supports the support cabinet 2 together with the stop universal wheel 1, so that the support cabinet 2 can be more Stably placed on the ground, the content not described in detail in this specification belongs to the prior art known to those skilled in the art.
