Filtering device for air water-making machine and having high-efficient back-flushing function

Abstract

The invention relates to a filtering device for an air water-making machine and having a high-efficient back-flushing function. The filtering device comprises a water inlet mechanism, a water outlet mechanism and a filtering mechanism, wherein the water inlet mechanism comprises a water inlet pipe, a water inlet, a sewage draining opening and a first piston; the filtering mechanism comprises a filtering warehouse, a filtering screen and a water outlet pipe; and the water outlet mechanism comprises a water purifying opening, a flushing opening and a second piston. The filtering device for the air water-making machine and having the high-efficient back-flushing function is exquisite in design and reasonable in structure, water flows in through the water inlet, purified water can be obtained at the water purifying opening; when the filtering net is inapparent in effect, the filtering net can be conveniently subjected to back flushing, and an iron block in a second rubber block and magnets in the flushing opening can enable the second piston to be in a closed state under a certain pressure, so that a rubber bag is expanded during water injection. Through the expanding and contraction of the rubber bag, water pressure during back flushing can be greatly increased, so that a favorable back flushing effect can be achieved.

Description

technical field [0001] The invention relates to a filtering device with high-efficiency backwashing function for an air water generator. Background technique [0002] With the improvement of people's living standards, people pay more and more attention to the sanitation of water. The water filter device can provide people with clean water, and the long-term use of the filter will reduce the adsorption capacity of the filter, and the reaction to the filter Flushing can effectively clean the filter screen. The existing backwashing technology generally needs to manually close the water inlet and the water purification port, which does not have the intelligence of the equipment, and there is no booster device during backwashing, so the cleaning effect is not good. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a filter device with high-efficiency backwashing function for air water generators in order to solve the de...
