[0043] The inner side of the water inlet pipe 31 is provided with a mounting step 311 with a mounting hole 3111; the switching device 40 includes a water inlet rod 41 disposed in the water inlet pipe 31 and movably connected to the mounting step 311, a connecting pipe 42 disposed above the mounting step 311 and connected to the upper end of the water inlet rod 41, and a spring 43 disposed between the connecting pipe 42 and the mounting step 311 and always providing elastic potential energy to the connecting pipe 42. A second groove is disposed at the upper end of the water inlet rod 41 to form a water flow channel 411 inside the water inlet rod 41, and a plurality of water inlet holes 412 connected to the water flow channel 411 are also disposed on the outer wall of the water inlet rod 41; the connecting pipe 42 is hollow inside and is used to connect the water flow channel 411 with the first water inlet channel 11. The upper end of the connecting pipe 42 is threadedly connected to the nozzle 10, and the lower end is threadedly connected to the water inlet rod 41.

[0044] Since the upper end surface of the tray 20 is an inclined surface, it is preferably set at an inclination angle of one degree toward the drain port 22 to facilitate drainage. Therefore, an elastic gasket 60 is set between the upper end surface of the tray 20 and the water inlet pipe 31, and an elastic step 61 is set on the upper end surface of the elastic gasket 60 and at the connection with the water inlet pipe 31. The setting of the elastic step 61 facilitates better installation of the water inlet pipe 31 on the tray 20.

[0045] A supporting step 413 is arranged below the water inlet rod 41, and a first sealing ring 70 is arranged between the supporting step 413 and the lower end surface of the mounting step 311. Under the action of the spring 43, the water inlet hole 412 is located in the mounting hole 3111, and the first sealing ring 70 is against between the mounting step 311 and the supporting step 413, thereby playing a sealing role and realizing water cut-off at the nozzle 10.

[0046] The working principle of the cup washer of the utility model is as follows:

[0047] By placing the cup on the hand wheel 50 and then pressing the cup downward, the water inlet rod 41 extends downward, and water flows into the water flow channel 411 through the water inlet hole 412, flows to the nozzle 10 and is sprayed out from multiple small holes, thereby washing the bottom and four walls of the cup. When the cup is released, the spring 43 rebounds and the water is turned off.
