Furthermore, the handle is provided with friction particles which are evenly distributed on the handle.

Furthermore, the base is provided with a first limiting groove on the outer side of the welding hard filter cylinder.

Furthermore, a first sealing rubber ring is embedded on the first limiting groove, and a filter screen cylinder is installed on the first sealing rubber ring.

Furthermore, a honeycomb through hole is formed in the filter screen cylinder, and the upper end of the filter screen cylinder is in contact with a second sealing rubber ring in a second limiting groove in the sealing cover.

Furthermore, an oval through hole is formed in the hard filter cylinder, and a first threaded connector is arranged at the upper end of the hard filter cylinder.

Furthermore, the middle part of the sealing cover is communicated, chamfering processing is carried out on the top of the sealing cover, and a second threaded interface is arranged at the joint of the sealing cover and the first threaded interface of the hard filter cylinder.

Furthermore, the second limiting groove is in interference fit with the second sealing rubber ring, and the first limiting groove is in interference fit with the first sealing rubber ring.

The beneficial technical effects related to the implementation of the utility model are as follows: because the cartridge filter can be dismantled through using to this device, and have the dual filtration, so solved and filtered inadequately, the difficult problem of clearing up of filter equipment has strengthened the result of use of device.
