Detailed Description

Referring to fig. 2 to 4, a dust cup assembly for a mite killing instrument comprises a cup body 1, wherein a mounting position 13 is arranged at the cup mouth of the cup body and connected with a mite killing instrument main body; 1 inside filter assembly 2 and install the annular mount 3 at 1 opening part of cup with the suspension of filter assembly 2 of being equipped with of cup, wherein, be sealing connection between the external diameter of

annular mount

3 and 1 rim of a cup of cup, its hole is equipped with and sinks to rank 31 sealed bearing to have filter assembly 2, the leakproofness is good, and overall structure is simple, only need during the installation with the annular mount joint at 1 rim of a cup of cup, pack in filter assembly 2 again, manufacturing cost is lower, easy and simple to handle swiftly when wasing simultaneously or changing the filter core as the loss piece.

The lateral wall of cup 1 is equipped with air intake 11, makes and forms dust storage bin 4 between 1 inner wall of cup and filtering component 2, the annular mount 3, makes the air current behind air intake 11, dust storage bin 4 and filtering component 2, flows by the air outlet 21 that is equipped with on the filtering component 2. And the filter component 2 is arranged at the opening of the cup body 1 for suspension, so that the occupied inner space of the cup body 1 is small, the dust storage capacity is large, and the inconvenience of frequently cleaning the dust cup component can be avoided.

Referring to fig. 5, the filter assembly 2 includes an inner filter hypa 5 as a filter element and an outer filter cage 6 as a support frame; the opening end of the filter cover 6 is provided with a sealing cover 7 which covers the inner layer filter handkerchief 5 together, and the air outlet 21 is positioned on the sealing cover 7.
