[0002] The significance of dust removal lies not only in purifying the air, but also in maintaining people's health and the good state of the production environment. Nowadays, dust removal devices are not only limited to factories or families. More and more people will install corresponding dust removal devices in the office to improve their office environment and reduce the discomfort of people's breathing during work.

[0003] After retrieval, the existing patent (publication number: CN215016713U) discloses a rapid dust removal device for indoor use, which is convenient for improving the automation degree of the device, improving the indoor air quality, reducing indoor dust, and improving the practicability and operability of the device; it includes a dust collection box, a suction fan, a suction gun, a storage box, a pull handle, a placement rack and a cleaning device. A chamber is arranged inside the dust collection box. The suction fan is fixedly installed at the left end of the dust collection box. The input end of the suction fan is communicated with a suction pipeline. The output end of the suction gun is connected to the input end of the suction pipeline. The output end of the suction fan is communicated with a first conveying pipeline. A discharge port is arranged at the top left area of the dust collection box and communicated with the chamber. The output end of the first conveying pipeline is connected to the left end of the discharge port.

At this time, use the filter screen 3 to filter out dust and other impurities in the air, and use the inclined diversion groove 4 to guide, so that the filtered dust and other impurities are transported and dropped into the ash collection hopper 6 through the ash discharge groove 5. Then the air is further adsorbed by the activated carbon adsorption plate 8 to improve the air dust removal and purification effect;

[0040] The servo motor 1101 can be started to drive the fixed groove 1105 to rotate, and the threaded cooperation between the fixed groove 1105 and the threaded block 1104 can be used to make the threaded block 1104 slide up and down to drive the cleaning brush plate 1103 to slide, so as to clean one side of the filter screen 3, and clean the dust and other impurities adhering to the surface thereof, and then the guide groove 4 can be used to guide the dust and other impurities filtered and cleaned by the filter screen 3 to be discharged from the ash discharge groove 5 to the inside of the ash collecting hopper 6 more quickly, so as to realize the automatic cleaning of the filter screen 3, avoid the cumbersome and inconvenient traditional method of frequently disassembling and assembling and cleaning the filter screen 3, and avoid the influence of the dust removal effect of the air intake due to the untimely cleaning by the staff, and at the same time, the ash collecting hopper 6 can be pulled regularly to make the slide plate 14 slide out of the inside of the slide groove 15, so as to facilitate the removal of the ash collecting hopper 6 and centrally treat the dust and other impurities inside;

[0041] At the same time, by toggling the mounting frame 101, the sliding block 104 is driven to slide inside the mounting groove 103 to compress the mounting spring 102 until it is completely disengaged from the mounting hole 105. Then, the filter screen 3 or the activated carbon adsorption plate 8 can be taken out from the shell 9 through the sealing plate 10, which is convenient for thoroughly cleaning the filter screen 3 or replacing the activated carbon adsorption plate 8 that is saturated with adsorption. Then, during installation, first toggle the mounting frame 101, and then insert the filter screen 3 and the activated carbon adsorption plate 8 into the shell 9 through the reserved groove 13, and use the sealing ring 12 to improve the sealing performance of the sealing plate 10 to the inside of the reserved groove 13 to avoid air leakage. At the same time, the elastic force of the mounting spring 102 is used to make the sliding block 104 slide and drive the mounting frame 101 to slide into the mounting hole 105, so as to achieve a firm engagement and fixation of the sealing plate 10, thereby achieving rapid disassembly and assembly of the filter screen 3 or the activated carbon adsorption plate 8.
