Example eight

The embodiment provides a hand washing device capable of adapting to different heights, and in a preferred embodiment, the hand washing device comprises a hand washing device main body 100, and two or more layers of hand washing grooves 11 are fixedly arranged in the height direction of the hand washing device main body 100.

As shown in fig. 14, the present embodiment is described by taking three layers of hand washing sink 11 as an example, and the number of layers of hand washing sink may be two, four, five or six. The three layers of hand washing grooves 11 are arranged at intervals along the height direction of the hand washing device main body 100, and each layer of hand washing groove 11 is arranged along the length direction of the hand washing device main body 100. Such as sink opening 111, is located in the front side wall of hand washing apparatus body 100. sink 11 may be of the construction shown in figure 14.

It should be noted that in this embodiment, the hand washing tank 11 may also adopt the structure of the indented hand washing tank shown in embodiment one, and/or embodiment two, and/or embodiment three, and/or embodiment four, and/or embodiment five, and/or embodiment six, and/or embodiment seven.

The air inlet pipe 31 is provided with an air inlet valve 32 for controlling the on-off of the air inlet pipe, and the liquid inlet pipe 21 is provided with a liquid inlet valve 22 for controlling the on-off of the liquid inlet pipe. In the present embodiment, the atomizing module may be, but not limited to, an atomizing module disclosed in CN201911021051.1, CN201580005933.2, or CN201010555807.3, that is, any structure capable of atomizing water into water mist and spraying the water mist.

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.

The negative pressure generating structure 52 and the anti-fog net 55 are preferably provided at the same time in this embodiment, and only one of them may be provided in practice.

Before use, the air inlet pipeline 31 is connected with an external air source, and the air source can be an air compressor or an air pump; the liquid inlet pipe 21 is connected with an external water source, the water source can be a water supply faucet or a water tank, and when the water tank is used, water in the water tank is conveyed into the liquid inlet pipe 21 through a water pump.

When the hand washing basin is used, the liquid inlet valve 22 is opened firstly, then the air inlet valve 32 is opened, or the liquid inlet valve 22 and the air inlet valve 32 are opened simultaneously, water and air enter the atomization module, then the water-air mixture (namely, mist) is sprayed out from the mist outlet 411 of the atomization module to the hand washing basin 11, and the sprayed mist has impact force, so that the hand washing basin can help people to wash hands. The spray flows into the flow guide cavity 551 after passing through the anti-fog net 55, and is not directly sprayed on the inner wall of the hand washing sink 11, so that the impact force between the spray and the inner wall of the hand washing sink 11 can be reduced, spray rebound is prevented, and the formation of water mist is reduced. The negative pressure generating structure 52 generates negative pressure to draw water mist in the hand washing sink 11 away, so that the water mist which is diffused near the hand washing sink 11 is reduced, and the possibility of spreading germs through the water mist is reduced.

In the present embodiment, the liquid inlet valve 22 and the air inlet valve 32 may be opened manually or automatically, for example, in a place where the flow of the hand washing person is small, the liquid inlet valve 22 and the air inlet valve 32 may be opened manually during hand washing, and may be closed during hand washing, or no internal electric signal may be realized during manual operation, so that the structure is simple.
