Description

Technical Field

[0001] This utility model relates to the field of kitchen and bathroom appliances technology, and in particular to a cup washer. Background Technology

[0002] Many existing multi-functional faucets or sinks are equipped with cup washers. These cup washers are connected to water pipes and have piston valves. When you need to clean baby bottles, stemmed glasses, or long cups, you place these bottles or cups upside down on the cup washer and press down to open the valve. The cup washer will then spray water to rinse the inside of the bottles or cups, making them easy to clean.

[0003] Because pressing the piston requires pushing it down, and in existing cup washer technology, the bottom of the piston and the return spring are completely immersed in water and in contact with the water, the return spring is prone to rusting or failure due to long-term immersion in water. In addition, the bottom area of ​​the piston is relatively large, and when pressing, the bottom of the piston will squeeze against the water. Therefore, it takes a lot of force to press the cup washer to make water flow, which is inconvenient to use and needs to be improved. Utility Model Content

[0004] To address the aforementioned problems, the present invention aims to provide a cup washer in which the bottom of the piston is provided with an isolation chamber that does not come into contact with water, a return spring is provided in the isolation chamber that does not come into contact with water, and water enters the internal water outlet from the side of the piston. The isolation chamber is provided with a pressure relief vent, which can reduce the piston pressing force and facilitate use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cup washer includes a connecting base, a piston valve core, a nozzle, and a water receiving tray. The connecting base has a piston hole connected to a water supply hole. The piston valve core moves up and down within the piston hole and has a water outlet hole connected to a water passage hole on the cylindrical surface of the piston valve core. Main sealing rings are respectively provided on the upper and lower cylindrical surfaces of the water passage hole. During the up and down movement of the piston valve core, the water passage hole may block or connect with the water supply hole. The bottom surface of the piston valve core has a mounting cavity, which, together with the space within the connecting base, forms an isolation chamber. A return spring is provided between the mounting cavity and the isolation chamber. The isolation chamber is open to the outside and ventilated.

[0006] Furthermore, the water receiving tray is sleeved on the upper end of the piston valve core, the output end of the water outlet extends to the top of the water receiving tray through a connecting pipe, and the nozzle is located at the output end of the water outlet.

[0007] Furthermore, as one embodiment, the lower end of the connecting base is provided with a through bottom hole connected to the piston hole, the water supply hole is located above the through bottom hole and vertically connected to the piston hole, the lower end of the piston valve core is inserted into the through bottom hole and moves up and down, and an isolation sealing ring is provided between the lower end of the piston valve core and the side wall of the through bottom hole, the isolation sealing ring is used to isolate the isolation chamber from the piston hole.

[0008] Furthermore, the connecting base is disposed in the water supply pipe, and the lower end of the connecting base is sealed to the inner wall of the water supply pipe. The water supply pipe is provided with a vent hole connected to the through bottom hole; the water supplied by the water supply pipe enters the piston hole through the water supply hole.

[0009] Furthermore, the water supply pipe is provided with an installation sleeve, the connecting base is detachably disposed in the installation sleeve, and a sealing gasket is provided between the lower end of the connecting base and the inner wall of the water supply pipe.

[0010] Furthermore, as another improvement, the connecting base includes an upper base and a lower base that are sealed together. The lower base has a blind hole connected to the piston hole at its lower part. The water supply hole is located in the lower base and is parallel to the blind hole. The water supply hole is connected to the piston hole in parallel. The lower end of the piston valve core is inserted into the blind hole and moves up and down. An isolation sealing ring is provided between the lower end of the piston valve core and the side wall of the blind hole. The isolation sealing ring is used to isolate the blind hole from the water supply hole.

[0011] Furthermore, the lower end of the lower base is connected to the water supply pipe, and the side of the lower base is provided with a vent hole connected to the blind hole.

[0012] This utility model has the following beneficial effects: 1. This utility model provides a water-free isolation chamber between the bottom of the piston valve core and the connecting base, and places the return spring in the isolation chamber so that it does not come into contact with water, thereby preventing the return spring from rusting or failing due to long-term immersion; in addition, the isolation chamber is open to the outside and ventilated, so that the gas in the isolation chamber will not be compressed when the piston valve core moves up and down in the piston hole, which can reduce the piston pressing pressure during cleaning and facilitate use.

[0013] 2. The connecting base of this utility model can be set as an integral structure. In this case, a through bottom hole is provided at the bottom of the connecting base to facilitate the insertion of the piston valve core into the piston hole through the through bottom hole.
