[0032] The working principle of the utility model is as follows: when in use, firstly connect the device to an external power source, and at the same time, transport the gas that needs to filter dust to the inside of the box body 1 through the air inlet pipe 4. When the gas enters the inside of the box body 1, it is located at the center of the filter screen 3. At the same time, the air outlet pipe 7 is connected to the gas storage tank. At the same time, the user presses the corresponding control button 15, and the fan 8 runs inside the air outlet pipe 7. When the fan 8 runs, it guides the air and gas inside the box body 1 to enter the inside of the gas storage tank through the air outlet pipe 7. The gas flow contacts the filter screen 3 at the same time and passes through the mesh of the filter screen 3. The dust in the gas can be filtered, so as to filter and remove the dust in the gas. When the filter 3 is damaged or the mesh of the filter 3 is clogged and the filter 3 needs to be disassembled, replaced or cleaned, the user first pulls the cover plate 12 to drive the sealing ring 13 to break contact with the inner wall of the box body 1, and the box body 1 can be opened. At the same time, the bolt 65 is rotated inside the vertical plate 62 to move upward. When the bolt 65 moves, the insertion rod 66 is pulled out of the slot 16. At the same time, under the elastic force of the spring 64 itself, the U-shaped clamping plate 61 is driven to move and reset. When the U-shaped clamping plate 61 moves, The moving rod 63 is also driven to move, and the U-shaped clamping plate 61 is disengaged from one side of the filter screen 3 while moving. At the same time, the user pulls the filter screen 3 to move toward the front of the box body 1. When the filter screen 3 moves, the top is disengaged from the bottom of the baffle 5, and the bottom of the filter screen 3 is disengaged from the top of the support block 2. The filter screen 3 can be disassembled, which is convenient for the user to disassemble and replace the filter screen 3 or clean the dust that blocks the mesh of the filter screen 3. When the filter screen 3 needs to be installed, first place the filter screen 3 on the top of the support block 2 and make the filter screen 3 between the two The U-shaped clamp 61 is positioned between the vertical plate 62, and the back side of the filter 3 is in contact with the limiting plate 17. At the same time, the user pushes one side of the moving rod 63 to move. When the moving rod 63 moves, the U-shaped clamp 61 is driven to move and contact the filter 3. When the moving rod 63 moves, the spring 64 is also driven to expand and contract. At the same time, the user rotates the bolt 65 inside the vertical plate 62 and rotates it downward. When the bolt 65 moves downward, it drives the insertion rod 66 to be inserted into the inside of the slot 16, thereby fixing the position of the U-shaped clamp 61 and the moving rod 63, thereby clamping and fixing the filter 3.
