Meanwhile, a second clamping protrusion 411 is arranged below the through hole section 413 in the screwing section 412, and the second clamping protrusion 411 is clamped with a second clamping groove 421 arranged on the screwing protrusion 42 to serve as a prompt for installing the dust cup 40 and the dust cup seat 10 in place. When the dust cup 40 and the dust cup seat 10 are installed in a screwing mode, the screwing protrusion 42 in the dust cup 40 is screwed into the screwing section 412 through the opening section 413 of the screwing groove 41 in the dust cup seat 10, and the second clamping groove 421 on the screwing protrusion 42 is clamped with the second clamping protrusion 411 in the screwing section 412, so that the dust cup 40 and the dust cup seat 10 are connected.

In addition, the dust cup 40 is provided with a positioning protrusion 44, and the positioning protrusion 44 is matched with a positioning groove 43 arranged in the dust cup seat 10 and used for limiting the circumferential installation direction of the dust cup 40 on the dust cup seat 10, so that when the dust cup 40 is installed in place, an air inlet 45 on the dust cup 40 is aligned and communicated with an air duct opening of the mite removal instrument 200.

In conclusion, the filter screen assembly 20 of the dust cup assembly 100 is detachably connected with the dust cup seat 10 through the first mounting structure, the filter element assembly 30 is detachably connected with the dust cup seat 10 through the second mounting structure, the filter screen assembly 20 and the filter element assembly 30 are separately mounted, meanwhile, the dust cup 40 is detachably connected with the dust cup seat 10 through the screwing groove 41 and the screwing protrusion 42, and the filter screen assembly 20 and the filter element assembly 30 are arranged in the dust cup 40, so that the installation and the detachment of all parts in the dust cup assembly 100 are more convenient, and the cleaning and the replacement of the filter screen assembly 20 and the filter element assembly 30 are facilitated. In particular, filter element assembly 30 does not fall out as a result of disassembly of filter screen assembly 20, resulting in greater stability of the installation of filter element assembly 30.
