Description

Technical Field

[0001] The utility model relates to the technical field of faucets, in particular to an automatic delayed cleaning faucet. Background Art

[0002] A time-delay faucet is a faucet with a delayed self-closing function, which is commonly used in the field of public health, such as (cleaning faucets in public toilets). Existing time-delay faucets are of two types: mechanical and infrared sensing. Among them, since infrared sensing faucets need to be continuously powered on for sensing, they consume a lot of energy, and in a humid environment, electrical appliances are easily damaged by moisture. Therefore, most people use mechanical time-delay faucets, which require pressing the faucet to open the mechanism, and the faucet will immediately discharge water and close with a delay. It has the advantages of no electricity consumption and is not easy to be damaged. However, the existing time-delay faucet will discharge water when the cover button is pressed, and when the hand is retracted to the water outlet of the faucet, there is no time to clean it, resulting in a waste of water resources. As the number of times increases, the waste of water resources increases randomly. Utility Model Content

[0005] Preferably, a reinforcing tube is fixedly connected to the axis of the first blocking block, a limiting strip is fixedly connected to the inner wall of the reinforcing tube, and the other side of the limiting strip extends to the inner cavity of the limiting groove and is slidably connected to the inner cavity of the limiting groove.

[0006] Preferably, grooves are provided at the top and bottom of the surface of the first blocking block and at corresponding positions on the inner wall of the connecting tube, and the inner cavity of the groove is sleeved with a sealing ring.

[0007] Preferably, a limiting ring is provided on the top of the first blocking block, and the surface of the limiting ring is fixedly connected to the inner wall of the connecting tube.

[0008] Preferably, a corrugated rubber tube is fixedly connected to the bottom of the first blocking block and located outside the spring, and the bottom of the corrugated rubber tube is fixedly connected to the bottom of the inner cavity of the connecting tube.

[0009] Preferably, the surface of the button is covered with an anti-slip cover, and the surface of the anti-slip cover is provided with anti-slip patterns.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The utility model presses the button downward, and the button drives the first blocking block and the second blocking block to move downward through the connecting rod. At this time, the water inlet is connected to the connecting cylinder, and the water inlet end of the water outlet pipe is blocked by the second blocking block. Then the user can put his hand at the bottom of the water outlet pipe. At this time, due to the friction between the first blocking block and the second blocking block, the first blocking block will be pushed to slowly return to its original position after the spring is compressed. At this time, the connecting rod can be driven upward by the first blocking block, and the connecting rod drives the second blocking block to move upward. At this time, the water inlet end of the water outlet pipe will be slowly connected, and water can be discharged. When the spring is completely restored to its original position, the water inlet will be blocked and no water will enter. Therefore, the function of automatic delayed water discharge can be realized. By adopting this device, water can be discharged after a period of time after the user presses it, thereby reducing the waste of water resources and bringing great convenience to daily use.

[0012] 2. The utility model can ensure the supporting strength of the first blocking block by providing a reinforcing tube, can limit the first blocking block by providing a limiting strip and a limiting groove, and can ensure the sealing of the water inlet by providing a groove and a sealing ring, and can support the top of the first blocking block by providing a limiting ring so that it will not be pulled upward.
