Self-cleaning tap for water purifier

Abstract

The invention relates to a self-cleaning tap for a water purifier. The self-cleaning tap comprises a water inlet pipe; the upper part of the water inlet pipe is sleeved with an adjuster; the bottom end of the water inlet pipe is sleeved with a pressure maintaining valve element; water outlet holes communicating with the water inlet pipe are formed in the pressure maintaining valve element; buckles are arranged on the periphery of the pressure maintaining valve element; an elastic piece is arranged between the adjuster and the pressure maintaining valve element and outside the water inlet pipe; the adjuster and the pressure maintaining valve element are sleeved with a shell; a slide rail matched with the buckles is arranged on the inner side surface of the shell; the adjuster adjusts the sizes of the water outlet holes in a manner that the elastic piece pushes the buckles on the pressure maintaining valve element to rotate along the slide rail of the shell and move up and down; a filter element is arranged in a part, below the pressure maintaining valve element, in the shell; a water collecting cavity is formed between the filter element and the pressure maintaining valve element; a cleaning device capable of being in vertical sliding fit with and rotating synchronous with the pressure maintaining valve element is arranged between the filter element and the shell; the shell is provided with an openable and closeable discharge port corresponding to the bottom end of the cleaning device; and water outlet ends are arranged under the filter element.

Description

technical field [0001] The invention relates to the field of faucets, in particular to a self-cleaning water purifier faucet. Background technique [0002] With the improvement of people's living standards and the enhancement of health awareness, higher requirements are put forward for the purity of water, especially drinking water and domestic water. Therefore, people are increasingly taking relevant purification measures at the taps at the end of water intake. There are generally two types of commonly used faucet purification devices. One is to directly add a water purification head with a filter to the water outlet of the faucet, and the other is to install a sedimentation elbow that can discharge impurities at the front of the faucet. The former method has poor cleaning effect and is easy to block and needs to be cleaned frequently, while the latter increases the number of pipe fittings, resulting in cumbersome operations and increased maintenance.
