The term "and / or" includes any and all combinations of one or more of the associated listed items.

[0042] An embodiment of this application provides a filtering device. As Figures 1 to 19 shown, the filtering device includes a housing 100, a cover 200, a filtering component 300, and a water inlet connector 400. The housing 100 has a receiving cavity 101 and an opening 102 communicating with the receiving cavity 101. The cover 200 is detachably disposed at the opening 102. Both the water inlet connector 400 and the filtering component 300 are disposed in the receiving cavity 101. Two ends of the water inlet connector 400 are respectively connected to the cover 200 and the filtering component 300. The filtering component 300 has a filtering groove 301. A water inlet 103 and a water outlet 104 communicating with the receiving cavity 101 are provided on a side wall of the housing 100.
