[0040] Refer to Figures 1 to 5 For a further description of an embodiment of an anti-static filter element for dust filtration of the present utility model.

[0041] An anti-static filter element for dust filtration, including a bottom cover 1 and a front cover 2. It should be noted that the bottom cover 1 is provided with a limit groove for fixing the motor 7, and further includes: two card seats 11, and the two card seats 11 are respectively disposed on the bottom cover 1 and the front cover 2. It should be noted that the card seat 11 is made of plastic, which does not generate static electricity, and the card seat 11 has a bayonet that can firmly hold the anti-static filter element; an anti-static filter cartridge 5 is disposed between the two card seats 11 for filtering and anti-static. It should be noted that the anti-static filter cartridge 5 is made of polyester long fiber coated with conductive fiber antistatic material, which is not only wear-resistant, has high strength and good air permeability, but also has good anti-static function.

[0042] A first anti-static net 3 is disposed between the two card seats 11 for eliminating static electricity; a second anti-static net 4 is disposed between the two card seats 11 for eliminating static electricity; a fixing device is disposed on the card seat 11 for fixing the second anti-static net , It should be noted that both the first anti-static net 3 and the second anti-static net 4 are made of aluminum metal, and this material can better eliminate static electricity.

[0043] Refer to Figure 3 and Figure 5 , as a preferred embodiment, the fixing device includes: a connecting portion disposed on the card seat 11; a driving portion disposed on the connecting portion.

[0044] With such a setting, the fixing device includes two parts, a driving part and a connecting part. The driving part consists of a circular plate 6 and a motor 7, which is used to provide power for the fixing device. The connecting part consists of a connecting rod 8, a fixing column 9 and an arc-shaped groove 10, which is used for connecting and fixing the fixing device and the card seat 11.

[0045] Reference Figure 3 and Figure 5 , as a preferred embodiment, the driving part includes: a circular plate 6, which is arranged on the card seat 11 and is rotatably connected to the card seat 11; a motor 7, which is arranged between the circular plate 6 and the bottom cover 1 and is fixedly connected to the circular plate 6, and a plurality of springs 12, and one ends of the plurality of springs are all arranged on the circular plate and are fixedly connected to the circular plate.

[0046] With such a setting, the motor 7 is fixed on the circular plate 6. The rotation of the motor 7 drives the circular plate 6 to rotate together. A sliding groove is arranged in the circular plate 6, which can allow the connecting rod 8 to slide therein. During the process of the motor 7 driving the circular plate 6 to rotate, the circular plate 6 drives the connecting rod 8 to slide in the sliding groove, and at the same time, the spring 12 will be compressed. When the motor 7 rotates in the reverse direction, the spring 12 rebounds and pushes the connecting rod back to its original position.

[0047] Reference Figure 5 , as a preferred embodiment, the connecting part includes: a plurality of connecting rods 8, and one ends of the plurality of connecting rods 8 are all arranged on the circular plate 6 and are slidably connected to the circular plate 6; a plurality of fixing columns 9, and the plurality of fixing columns 9 are respectively arranged at the other ends of the connecting rods 8 and are fixedly connected to the other ends of the connecting rods 8; a plurality of arc-shaped grooves 10, and the plurality of arc-shaped grooves 10 are all arranged on the card seat 11.

[0048] With such a setting, the connecting rod 8 can rotate along with the circular plate 6, driving the fixing column 9 to move in the arc-shaped groove 10. The specific operation of this device is as follows: start the motor 7 to rotate clockwise, driving the circular plate 6 to rotate clockwise. The circular plate 6 will drive the connecting rod 8 to rotate, and at the same time, the connecting rod will compress the spring 12. The connecting rod 8 drives the fixing column 9 to move along the arc-shaped groove 10, increasing the distance between the fixing column 9 and the card seat 11, and then the second anti-static net 4 can be placed. Then the motor 7 rotates counterclockwise to drive the circular plate 6 to rotate clockwise. The spring 12 rebounds in the circular plate 6 and acts on the connecting rod 8, causing the connecting rod 8 to slide while rotating along with the circular plate 6. The connecting rod 8 drives the fixing column 9 to move along the arc-shaped groove 10, reducing the distance between the fixing column 9 and the card seat 11, and pressing the second anti-static net 4 firmly.

[0049] This device is provided with a first anti-static net 3 and a second anti-static net 4. Through the pin design, this kind of net can quickly and extensively eliminate static electricity. At the same time, the first anti-static net 3 and the second anti-static net 4 can be disassembled and cleaned. This device is provided with an anti-static filter cartridge 5. The filtering material of this filter cartridge uses polyester long fiber coated with conductive fiber anti-static material. By adding conductive fiber to the original polyester long fiber material, it has the anti-static function on the basis of the original filtration and can prevent electrostatic sparking.

[0050] Working principle: When this device is working, it is placed in a specific filtering device. Under the air extraction state of the filtering device, the dirty air with dust will pass through the first anti-static net 3, enter the anti-static filter cartridge 5, and then pass through the second anti-static net 4 to complete the filtration. The filtered air is exhausted from the filtering device. When the dirty air with dust passes through the first anti-static net 3, the first anti-static net 3 will eliminate the static electricity carried by the dust in the air, and then enter the anti-static filter cartridge 5 for dust removal. Under the state of compressed air backwashing of the filtering device, the air first passes through the second anti-static net 4. The second anti-static net 4 eliminates the static electricity of the air, enters the anti-static filter cartridge 5, and knocks off the remaining dust on it. Both the first anti-static net 3 and the second anti-static net 4 of this device can be disassembled and cleaned. The first anti-static net 3 is placed between the card holder 11, the bottom cover 1 and the front cover 2. When cleaning is needed, just remove the bottom cover 1 and the front cover 2 to take it out. The second anti-static net 4 is placed between the card holder 11 and the fixed column 9. When cleaning is needed, start the motor 7 to make it rotate clockwise, drive the circular plate 6 to rotate clockwise. The circular plate 6 will drive the connecting rod 8 to rotate. At the same time, the connecting rod 8 will compress the spring 12. The connecting rod 8 drives the fixed column 9 to move along the arc groove 10, increasing the distance between the fixed column 9 and the card holder 11, and then the second anti-static net 4 can be taken out.

[0051] The above description of the embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
