Description

Technical Field

[0001] This utility model relates to the field of faucet technology, specifically to a water purifier faucet that automatically drains residual water from the pipe. Background Technology

[0002] As people's living standards improve, their requirements for drinking water are also increasing. Water purifier faucets have become frequently used kitchen and bathroom products, greatly contributing to consumers' health. However, with existing water purifier faucets, water remains in the outlet pipe after being turned off, becoming residual water. When using the water the next morning, this residual water means drinking overnight water, which may also be contaminated, posing a significant health risk, especially to infants and pregnant women, resulting in a poor user experience. Therefore, to avoid the shortcomings of existing technology, it is necessary to improve it. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings and deficiencies in the existing technology and provide a water purifier faucet with a simple structure that automatically drains residual water from the pipe.

[0004] This utility model is achieved through the following technical solution:

[0005] A water purifier faucet that automatically drains residual water from its pipe includes a faucet body, a push-button valve core mounted on the side of the faucet body, a piston capable of lateral movement on the inner side of the push-button valve core, a water outlet bend mounted on the top of the faucet body, a water passage pipe communicating with the water outlet bend on the piston, a drain hole and a water inlet hole respectively on the bottom of the push-button valve core, a drain pipe communicating with the drain hole on the inner side of the faucet body, a water inlet pipe communicating with the water inlet hole on the inner side of the faucet body, and a drain through hole corresponding to the drain hole on the outer side of the water passage pipe.

[0006] Furthermore, a pressing rod is installed on the inner side of the pressing valve core, the pressing rod is connected to a rotating rod, the rotating rod abuts against the piston, and a spring is installed on the inner side of the pressing valve core to abut against the piston.

[0007] Furthermore, the pressing valve core includes a housing and a bottom shell installed at the end of the housing.

[0008] Furthermore, a first O-ring and a second O-ring are respectively fitted on the outer side of the piston, and the first O-ring and the second O-ring are respectively located on both sides of the drain hole.

[0009] Furthermore, a third O-ring is fitted on the outer side of the end of the water pipe.

[0010] Furthermore, a fourth O-ring is installed at the end of the bottom shell, a fifth O-ring is fitted on the outer side of the outer shell, and a sixth O-ring is fitted on the outer side of the bottom shell.

[0011] Furthermore, a seventh O-ring is provided at the connection between the outer shell and the bottom shell.

[0012] Furthermore, the bottom shell is provided with a spring positioning mounting groove, and the piston is provided with a stop plate for the spring to abut against.

[0013] Furthermore, a protrusion is provided at the contact point between the rotating rod and the piston.

[0014] Furthermore, the pressing rod is connected to a button.

[0015] Compared to existing technologies, this utility model features a push-button valve core installed on the side of the faucet body. The inner side of the push-button valve core has a piston capable of horizontal movement. The piston has a water pipe connected to the water outlet bend. The bottom of the push-button valve core has a drain hole and a water inlet hole. The inner side of the faucet body has a drain pipe connected to the drain hole and a water inlet pipe connected to the water inlet hole. The outer side of the water pipe has a drain through hole corresponding to the drain hole. When the push-button is pressed and springs back, the piston retracts under the spring force, connecting the water inlet hole to the water outlet bend, allowing water to flow out of the bend – this is the normal water flow state. When the push-button is pressed and does not spring back under the action of the rotating rod, the piston's drain through hole connects to the drain hole, resulting in a drain state. Simultaneously, the water inlet hole is closed. Due to the water's own gravity, residual water in the water outlet bend is automatically and quickly discharged, preventing overnight water accumulation, avoiding contamination of purified water, and preventing adverse effects on the health of infants and pregnant women. This ensures the drinking water safety of infants and pregnant women and provides excellent performance. Attached Figure Description
