When the filter needs to be cleaned, the fixing block 23 is removed and the first baffle 22 is slid away from the filter assembly 4. When the first baffle 22 slides, the slide groove 24 and the slider 25 cooperate to limit the movement trajectory of the first baffle 22. The first baffle 22 falls into the inner cavity of the slide groove 24, so that the inner cavity of the filter can be directly cleaned, which solves the technical problem of complicated steps when cleaning the filter.

[0025] Furthermore, Figure 2 , Figure 4 and Figure 5 As shown: the end of the sliding component 2 away from the filter component 4 is provided with a drainage component 3, the drainage component 3 includes a bracket 31, a protective rod 32 is provided on the side of the bracket 31, a fan 33 is provided in the inner cavity of the protective rod 32, a sawtooth opening 34 is provided on the surface of the protective rod 32, a first support plate 35 is provided in the inner cavity of the bracket 31, the inner cavity of the sliding component 2 is provided with a filter component 4, the filter component 4 includes a second connecting pipe 41, the inner cavity of the second connecting pipe 41 is provided with a second support plate 42, the surface of the second support plate 42 is provided with a vent 43, the number of the vent 43 is four, and the four vents The openings 43 are all opened on the surface of the second support plate 42, and a filter housing 44 is arranged on the side of the ventilation opening 43, and a filter element 45 is arranged in the inner cavity of the filter housing 44, and a second baffle 46 is arranged in the middle of the filter element 45, and a filter screen 47 is arranged at the end of the second connecting pipe 41 away from the filter housing 44.
