In one embodiment, the sealing unit 500 includes a slider 510, a shutter 520, and a fourth driving assembly.

The number of the sliding blocks 510 is two, and the two sliding blocks 510 are oppositely arranged in the machine body 100 along the longitudinal direction, namely, one sliding block 510 is arranged above and the other sliding block 510 is arranged below. The two sliding blocks 510 may be longitudinally close to or far from each other in the machine body 100, and a water absorbing sponge 540 is fixedly provided at the opposite side of the two sliding blocks 510. The absorbent sponge 540 has the dual functions of absorbing water and strong deformation. When the hand is inserted into the cleaning unit, the two sliding blocks 510 are close to each other, so that the water absorbing sponge 540 provided on the sliding blocks 510 are close to each other, and when the water absorbing sponge 540 contacts the hand, the water absorbing sponge 540 is deformed, thereby achieving the purpose of sealing the window 110, and the water absorbing sponge 540 is deformed as soon as being stressed, so that discomfort of the hand is not caused.

A barrier 520 is secured to the side of the slider 510 facing the hand washing assembly 210 and serves to block the water absorbing sponge 540 to prevent the portion of the water absorbing sponge 540 remote from the window 110 from being wetted by water and cleaning composition sprayed from the shower unit during the hand washing process.

The fourth driving assembly is disposed in the body 100 and is used for driving the two sliders 510 toward or away from each other.

In use, when a hand is inserted into the window 110, the fourth driving assembly drives the two sliders 510 to approach each other, so that the water absorbing sponge 540 provided on the sliders 510 contacts the hand and deforms along with the shape of the hand, thereby achieving the purpose of sealing the window 110. After washing the hands, the fourth drive assembly drives the two slides 510 away from each other, thereby opening the window 110 to facilitate withdrawing the hands.

Specifically, the fourth driving assembly includes a fourth motor 531, a fourth lead screw 532, and a fourth guide bar 533. The first ends of the two sliding blocks 510 are provided with limiting sliding holes, and the fourth guide rod 533 is slidably connected with the sliding blocks 510 through the limiting sliding holes. The fourth screw 532 is rotatably disposed at the second end of the slider 510, two thread segments with the same pitch and opposite thread directions are disposed on the fourth screw 532, and the fourth screw 532 is in threaded connection with the two sliders 510 through the two thread segments. When the fourth screw 532 rotates in the forward direction, the fourth screw 532 drives the two sliders 510 to approach each other; and when the fourth screw 532 rotates reversely, the fourth screw 532 drives the two sliders 510 away from each other. The power output shaft of the fourth motor 531 is in driving connection with a fourth screw 532.

In use, during the hand washing process, the fourth motor 531 drives the fourth screw 532 to rotate forward, so as to drive the two sliding blocks 510 to approach each other, and the water absorbing sponge 540 disposed on the sliding blocks 510 contacts with the hand and deforms along with the shape of the hand, thereby achieving the purpose of sealing the window 110. After washing the hands, the fourth motor 531 drives the fourth screw 532 to rotate in the opposite direction, thereby driving the two sliders 510 away from each other to open the window 110.

The sealing unit 500 with the structure has the advantages of simple structure and reasonable design, and has better sealing effect by utilizing the strong deformation effect of the water absorbing sponge 540.
