Further, the lower end cover is provided with a pipe.
Further, the pore diameters of the porous filter pipe and the filter cartridge are equal, and the distance between the upper filter hole and the lower filter hole of the filter cartridge is equal to the diameter of the filter hole of the porous filter pipe.
Further, the nozzle of the filter cartridge is arranged at the bottom, and the diameter of the nozzle is larger than that of the inlet pipe.
Compared with the prior art, the utility model has the following beneficial effects:
according to the utility model, the filter cylinder is controlled to move upwards by rotating the rotary cap, so that the filter cylinder and the filter holes of the porous filter tube are staggered, and the pore diameter of the filter hole of the dust removing filter element is changed from small to large, so that the dust removing filter element can filter dust with smaller particle size, and the filtering range is wider.

Detailed Description
For the purpose of further illustrating the various embodiments, the present utility model provides the accompanying drawings, which are a part of the disclosure of the present utility model, and which are mainly used to illustrate the embodiments and, together with the description, serve to explain the principles of the embodiments, and with reference to these descriptions, one skilled in the art will recognize other possible implementations and advantages of the present utility model, wherein elements are not drawn to scale, and like reference numerals are generally used to designate like elements.
According to an embodiment of the present utility model, a multi-aperture switching dust filter cartridge is provided.
Embodiment one:
as shown in fig. 1-2, the porous switching dust-removing filter element comprises a porous filter tube 1, wherein an upper end cover 2 and a lower end cover 3 are fixedly connected to the upper end and the lower end of the porous filter tube 1 respectively, a threaded hole 4 is formed in the center of the upper end cover 2, a threaded rod 5 is connected in the threaded hole 4 in a threaded manner, a filter cartridge 6 is arranged in the porous filter tube 1, a switching groove 7 is formed in the center of the top end of the filter cartridge 6, a rotary connecting block 8 is arranged in the switching groove 7, the top end of the rotary connecting block 8 is fixedly connected with the bottom end of the threaded rod 5, and a rotary cap 9 is arranged at the top end of the threaded rod 5;
embodiment two:
the lower end cover 3 is provided with a pipe inlet 10;
the pore diameters of the porous filter tube 1 and the filter cartridge 6 are equal, and the distance between the upper filter hole and the lower filter hole of the filter cartridge 6 is equal to the diameter of the filter hole of the porous filter tube 1;
the nozzle of the filter cartridge 6 is arranged at the bottom, and the diameter of the nozzle is larger than that of the inlet pipe 10;
the working principle of the utility model is as follows:
when the aperture of the filter holes is changed, the filter core is rotated clockwise, the screw cap 9 drives the threaded rod 5 to rotate clockwise and move upwards, then the threaded rod 5 drives the filter cartridge 6 to move upwards, and in the process that the filter cartridge 6 moves upwards, the filter holes on the filter cartridge 6 are staggered with the filter holes on the porous filter tube 1, so that the filter diameter of the filter core is gradually changed from minimum to maximum, the multi-filter-diameter switching of the filter core is realized, and dust with smaller particle size can be filtered;
according to the utility model, the filter cartridge 6 is controlled to move upwards by rotating the rotary cap 9, so that the filter cartridge 6 is staggered with the filter holes of the porous filter tube 1, and the pore diameter of the filter hole of the dust removing filter element is changed from small to large, thus the dust removing filter element can filter dust with smaller particle size, and the filtering range is wider;
when the rubber plug is disassembled, the pressing block 5 is pressed firstly, the clamping strip 8 is retracted into the through groove 7, then the rubber plug body 2 is pulled out of the pipe body 1, and then the pressing block 5 is loosened, so that the clamping strip 8 is ejected out of the through groove 7, the labor intensity of workers is reduced, the rubber plug is more labor-saving to install and disassemble, and the installation and disassembly efficiency of the rubber plug is improved.
