In some specific embodiments, the number of ultraviolet lamps 503 may be set to one, two, four, five, etc., which is not specifically limited. In this embodiment, there are four ultraviolet lamps 503, which are arranged around the open end of the cleaning pool 2 and are evenly distributed; thus, the user's hands can be sterilized and disinfected in all directions.

In other embodiments, the ultraviolet lamp 503 may be directly embedded in the inner wall of the cleaning tank 2 , and a transparent closing plate may be provided at the position of the inner wall of the cleaning tank 2 corresponding to the ultraviolet lamp 503 . While ensuring that the ultraviolet lamp 503 can irradiate the interior of the cleaning pool 2 , it can further effectively prevent water, disinfectant and protective liquid from being splashed onto the ultraviolet lamp 503 .

As shown in FIG. 1 to FIG. 3 , optionally, a sewage outlet 201 is further provided at the bottom of the cleaning pool 2 to discharge the sewage generated during the hand-washing process. It can be understood that the inner wall of the cleaning tank 2 has a smooth surface, so that sewage and the like can slide to the bottom of the cleaning tank 2 and then be discharged through the sewage outlet 201 .

In the embodiment, the sewage outlet 201 is also connected with the purification unit 11; the end of the purification unit 11 away from the sewage outlet 201 is communicated with the sewer pipe; the purification unit 11 is arranged in the box body 1, and is set close to the bottom of the box body 1, so as to facilitate purification The unit 11 is connected to the sewer pipe. In use, the sewage enters the purification unit 11 after passing through the sewage outlet 201, and the purification unit 11 purifies the sewage, and then discharges the purified water.

Specifically, the purification unit 11 includes a solid filter assembly 1101 and a negative ion carbon core 1102 that are communicated with each other. The solid filter assembly 1101 is arranged between the sewage outlet 201 and the negative ion carbon core 1102; the solid filter assembly 1101 is communicated with the sewage outlet 201 through the third infusion pipe 1609; the output end of the negative ion carbon core 1102 can be communicated with the sewer pipe. Among them, the solid filter assembly 1101 can filter and collect larger solid impurities in the sewage; the negative ion carbon core 1102 can adsorb and filter the tiny suspended solids and some dissolved substances in the sewage to purify the sewage.

As shown in FIG. 8 , the solid filter assembly 1101 includes a water inlet pipe 1101a, a collection cage 1101b and a water outlet pipe 1101c. The water inlet pipe 1101a and the water outlet pipe 1101c are arranged in communication;

The collection cage 1101b is provided at the connection of the water inlet pipe 1101a and the water outlet pipe 1101c. Specifically, the collection cage 1101b is transverse to the connection between the inlet pipe 1101a and the outlet pipe 1101c, so that the sewage discharged from the inlet pipe 1101a passes through the collection cage 1101b before entering the outlet pipe 1101c.
