Abstract

The utility model provides an automatic wash filter core water purifier, including the filter core, crack and intelligent control case, upper end at the filter core cap sets up the water inlet, lower extreme at the filter core cap sets up the drain, there is a purified water export at the afterbody center of filter core shell, and simultaneously, leave a crack between the inner face of filter core cap and the filter core cross-section, and the runoff in its crack will be less than the runoff of water inlet, thus, just can make all be covered with the high pressure on the filter core cross-section, high velocity of flow flowing water, utilize the high pressure that the running water formed on the filter core cross-section, high velocity of flow flowing water comes the automatic impurity that washes attached to on the filter core cross-section, thereby reach the purpose of the filter core of self-cleaning water purifier.

Description

Water purifier capable of automatically cleaning filter element

Technical Field

The present invention belongs to the field of design and manufacture technology of water purifier with automatic cleaning filter element.

Background

At present, with the improvement of living standard and the enhancement of health consciousness of people, a plurality of families consider mounting a water purifier in a kitchen, because tap water is filtered and disinfected, but secondary pollution is often caused in the process of conveying. The world health organization has also pointed out that tap water contains over seven hundred organic chemical pollutants, and therefore, a conditioned household usually chooses to install a water purifier, at least a pre-filter if conditions do not allow it. China has a plurality of old pipelines in cities, and the secondary pollution of water entering households is serious. This is also the case for many people: if the water is not at home for a long time, the water can flow out from the boiling water faucet when the water returns home, and the water can become clear after flowing for a while. The tap in the family is unscrewed, and the inside also has a lot of dregs and deposit, and the equipment of wading in the family is bad easily, and the filter core of water purifier is changed frequently, so there are a lot of families again and select a leading filter of installation now, especially the family has installed the water purifier, if do not install leading filter, big impurity in aquatic will directly get into the water purifier, just very big to the loss of filter core and machine, and the filter core just needs often to be changed.

However, regardless of whether or not the pre-filter is installed, the cross section of the front end of the filter element, i.e., the water inlet, is accumulated with various kinds of impurities mixed together and nausea and diverse sticky substances at the water inlet every time the water purifier is used for a certain period of time, but every household using the water purifier actually drinks the tap water and is filtered by the sticky substances, so called "purified water". All water purifiers sold in the market at present, whether made in China or imported, always do not solve the problem of how to automatically clean pollutants adsorbed on the front end section of the filter element.
