DETAILED DESCRIPTION

[0019] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

Under the connection of the spring 13, the filter element 11 is constantly vibrating, thereby shaking off the pollutants and dust attached to the surface of the filter element 11, effectively removing the pollutants on the filter element 11, restoring its filtering capacity, and extending the service life of the filter element 11; the jet mechanism 3, the jet mechanism 3 includes a pipe network 31 fixed on the inner wall of the housing 1 and located on one side of the output end of the filter element 11, and a plurality of evenly distributed high-pressure nozzles 311 are arranged on the pipe network 31. The jet mechanism 3 also includes an air supply member 32 for supplying air to the pipe network 31. The pipe network 31 is supplied with air by the air supply member 32, and the gas is ejected from the high-pressure nozzle 311 to form high-pressure gas, which is sprayed to the filter element 11, so that the shaken dust can be blown off the filter element 11, the cleaning is more thorough, the cleaning effect is better, and the service life of the filter element 11 is increased.

[0021] In this example, see Figure 2 , Figure 3 and Figure 6 The driving member 22 includes a driving motor 221 arranged on the housing 1, an output rod 222 is fixed on the output end of the driving motor 221, a bevel gear 223 is fixedly sleeved on the output rod 222, a connecting rod 224 is rotatably and penetrated on the housing 1, the cam 21 is fixed to one end of the connecting rod 224, and a bevel gear 225 meshing with the bevel gear 223 is fixedly sleeved on the other end of the connecting rod 224, the driving motor 221 drives the output rod 222 to rotate, and the bevel gear 223 on the output rod 222 rotates, and the bevel gear 223 drives the meshing bevel gear 225 to rotate, thereby rotating the connecting rod 224, and finally rotating the cam 21, continuously hitting the filter element 11, and shaking off the dust on the filter element 11.

[0022] To improve the effectiveness of cleaning, see Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7The air supply member 32 includes an air supply pipe 321 installed on the inner wall of the shell 1, a one-way valve is arranged inside one end of the air supply pipe 321, a piston 322 is movably arranged inside the air supply pipe 321, the pipe network 31 and the air supply pipe 321 are connected through a connecting pipe 323, one end of the connecting pipe 323 connected to the air supply pipe 321 is located between the piston 322 and the one-way valve, a linkage is connected between the piston 322 and the output rod 222, the linkage drives the piston 322 to reciprocate, and when the piston 322 is away from the one-way valve, the one-way valve opens , the gap between the piston 322 and the one-way valve becomes larger, and the external gas enters through one end of the air supply pipe 321. When the piston 322 is close to the one-way valve, the one-way valve is closed and the gas cannot be discharged. At this time, the gas enters the pipe network 31 and is finally ejected from a plurality of high-pressure nozzles 311 to clean the filter element 11. It should be noted that the diameter of the air supply pipe 321 is much larger than the diameter of the pipe network 31 and the high-pressure nozzle 311. Only in this way can the high-pressure nozzle 311 eject high-pressure gas to better blow off the dust on the filter element 11. The linkage member includes a driving wheel 324 fixedly mounted on the output rod 222, a linkage rod 325 is rotatably mounted on the inner wall of the housing 1, a driven wheel 326 is fixedly mounted on the linkage rod 325, and an integrated transmission belt 327 is mounted between the driven wheel 326 and the driving wheel 324. The driving motor 221 drives the output rod 222 to rotate, and the driving wheel 324 mounted on the output rod 222 rotates, and the driven wheel 326 is driven to rotate through the transmission belt 327, and the driven wheel 326 thereby drives the linkage rod 325 to rotate, and the linkage rod 325 A connecting rod 1 328 is fixed at the end, one end of the connecting rod 1 328 is hinged to a connecting rod 2 329, the other end of the connecting rod 2 329 is hinged to a connecting rod 3 3210, the other end of the connecting rod 3 3210 passes through the interior of the air supply pipe 321 and is fixed to the piston 322. The connecting rod 1 328, the connecting rod 2 329, the connecting rod 3 3210 and the piston 322 form a motion mechanism, which will drive the piston 322 to reciprocate along the interior of the air supply pipe 321 when the air supply pipe 321 limits the piston 322, thereby achieving the effect of continuous air supply.

[0023] For further information, see Figure 5The one-way valve includes a retaining ring 3211 fixed on the inner wall of the air supply pipe 321. There are two retaining rings 3211. A blocking ball 3212 is arranged between the two retaining rings 3211. The diameter of the blocking ball 3212 is smaller than the inner diameter of the air supply pipe 321 and larger than the inner diameter of the retaining ring 3211. A spring 2 3213 is connected between the retaining ring 3211 close to the piston 322 and the blocking ball 3212. In a natural state, the blocking ball 3212 fits against the inner wall of one of the retaining rings 3211 to ensure sealing. When the piston 322 When far away from the one-way valve, the external air pressure is greater than the air pressure between the one-way valve and the piston 322. At this time, the external gas pushes the stuck ball 3212 to move. At this time, the one-way valve opens and the external air enters. When the piston 322 is close to the one-way valve, the external air pressure is less than the air pressure between the one-way valve and the piston 322. At this time, the gas between the one-way valve and the piston 322 pushes the stuck ball 3212 to move. At this time, the one-way valve is closed, thereby discharging the gas into the pipe network 31, and finally spraying it out from a number of high-pressure nozzles 311 to form high-pressure gas.

A plurality of evenly distributed filter holes 151 are provided on the filter plate 15 to intercept impurities and dust with larger particle sizes. Through pre-filtration, larger particles are prevented from entering the filter element 11, thereby extending the service life of the filter element 11 and improving the filtering effect; the filter plate 15 is movably arranged inside the housing 1, and a plurality of evenly distributed through holes 152 are penetrated through the filter plate 15. A plurality of screws 121 are fixed on the side of one mounting plate 12 facing away from the filter element 11.
