[0023] The technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings in the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present embodiment, rather than all the embodiments. Embodiment 1

[0024] Referring to Figures 1 - 4 , an improved filter includes:

[0025] Base 1;

[0026] Guiding bosses 2, fixedly arranged on the outer side of the base 1, and a plurality of guiding bosses 2 are provided to play a guiding role during installation and prevent tilting during the installation process;

[0027] Outer protective net 3, arranged on the top of the base 1, and a filter element 4 is arranged inside the outer protective net 3. The outer protective net 3 protects the filter element 4;

[0028] Double-layer gasket 5, arranged on the top of the outer protective net 3. The double-layer gasket 5 adopts the form of a double-layer gasket to double-guarantee that the product will not leak.

[0029] In this embodiment, a top cover 6 is installed on the double-layer gasket 5, and a through hole 8 is provided on the top cover 6.

[0030] In this embodiment, a large handle 7 is fixedly installed on the top of the top cover 6. The large handle 7 is used to provide a good air flow channel for the product and is also convenient for grasping.

[0031] In this embodiment, an installation groove 9 is formed in the top of the base 1. The bottom of the outer guard net 3 is fixedly installed with an installation block 10. The installation block 10 is clamped with the installation groove 9. A plurality of vertical holes are provided in the installation block 10, and bolts 11 are arranged in the plurality of vertical holes. A plurality of threaded grooves 12 are formed in the bottom inner wall of the installation groove 9. The bottom end of the bolt 11 is in threaded connection with the corresponding threaded groove 12. The installation block 10 and the installation groove 9 are fixedly connected by bolts and threaded grooves and can be disassembled, so that the outer guard net 3 can be detached.

[0032] In this embodiment, the base 1 has a guiding boss 2, which can play a guiding role during installation and prevent inclination during the installation process. In the form of a double-layer gasket 5, it double-guarantees that the product will not leak. The design of the large handle 7 provides a good air flow channel for the product and is also convenient for grasping. The outer guard net 3 plays a protective role for the filter element 4, and it is not easy to damage the filter element 4 when touching or installing the filter. Embodiment 2
