It should be noted that the spray supply module may also be, but is not limited to, an atomizing faucet as disclosed in CN201610227831.1, as long as it is configured to provide a mist spray into the sink 11.

In this embodiment, as shown in figure 19, the sink opening 111 is located at the front end and the bottom of the sink 11 is located behind and below the sink opening 111, through which one can insert one's hands into the sink 11 for cleaning. It should be noted that in this embodiment, the hand washing sink 11 may also be a retracting hand washing sink structure in the first to seventh embodiments, such as shown in fig. 20 and 21; of course the sink 11 may also be an open top sink structure as disclosed in the prior art, such as the open top sink structures disclosed in CN201220638919.x, CN201410162428.6 or CN 201710836228.8.

As shown in fig. 19, in one embodiment, the demisting module comprises a negative pressure generating structure 52, and an air inlet of the negative pressure generating structure 52 is communicated with the hand washing tank 11 through an air suction pipe 51; for example, an air suction opening 13 is arranged at the rear side of the hand washing sink 11, and the inlet end of the air suction pipe 51 is connected with the air suction opening 13; of course, the suction opening 13 may not be provided separately, but the inlet end of the suction pipe 51 may be connected to the drain outlet 12 of the sink. In the present embodiment, the negative pressure generating structure 52 may be a negative pressure fan or other structure generating negative pressure, such as the structure generating negative pressure disclosed in CN 201010531757.5.

In another embodiment, the demisting module comprises an anti-fog net 55 arranged on the inner wall of the hand washing sink 11, the anti-fog net 55 is a net structure with meshes, a flow guide cavity 551 is arranged between the anti-fog net 55 and the inner wall of the hand washing sink 11, and the flow guide cavity 551 is communicated with the sewage discharge outlet 12.
