Water purifier with closed waterway switcher

Abstract

The invention relates to the water treatment industry, in particular to deep filtration and purification of drinking water. The invention discloses a water purifier with a closed waterway switcher. The water purifier comprises a filter element, and a pedestal provided with water inlet and outlet pipeline interfaces and a filter element pipeline interface. The water purifier is characterized by also comprising the closed waterway switcher; the closed waterway switcher is contacted and matched with the pedestal through a fastening device to form a whole, and the external water port of the closed waterway switcher is connected with the water inlet and outlet pipeline interfaces of the pedestal respectively; the controlled water port of the closed waterway switcher is connected with the filter element pipeline interface to form a positive water through filter passage of the filter element; and the related switching water port of each disc is newly butted by position movement of a control piece in a shell of the closed waterway switcher to form a negative water through backwashing passage of the filter element. The water purifier has the advantages that: the assembly and the manufacture are simple and convenient, and the production quality and the efficiency are high; the inspection is convenient and fast; and the maintenance is convenient and fast, the water purifier can be maintained by a user so that the expenditure is saved and the water purifier is also convenient for remote users, and popularization of the water purifier is favorable.

Description

technical field [0001] The invention relates to the water treatment industry, and specifically relates to the deep filtration and purification of drinking water. Background technique [0002] At present, water purifiers are relatively popular in China. When using water, the water purifier is used to filter the water and the impurities caused by the water pipeline in depth, which better protects the health of users. Yet, along with the popularization of water purifier, their defect and deficiency also gradually exposed in application aspect. After the filter element of the water purifier is used for a period of time, the filter material of the filter element is gradually blocked by impurities and adsorbed on the outer surface of the filter material, resulting in a significant decline in filtration and adsorption effects. The "pollution" degree of the filter element impurities exceeds the "pollution" degree of the drinking water itself, so that the filter element becomes a n...

AI Technical Summary

Problems solved by technology

For the machine base with unsealed connection interface, remove the related devices and reassemble the waterway switcher. As the waterway switcher is assembled, the assembly efficiency of the machine base is extremely low, so the price of the corresponding products is relatively high.

Water purifiers without the "recoil" function are unwilling to use because users are worried about the rapid decline of the purification effect and poor stability, and are afraid of secondary pollution caused by excessive retention of impurities in the filter element.

In addition, when the water purifier is repaired, since the inspection conditions are not available, the repair of the relevant waterway switcher must be returned to the factory for repair

The above defects and deficiencies have seriously affected the upgrading and popularization of water purifier products
