Water purifier

Abstract

The invention relates to a water purifier, which includes a host hanging plate, and a coarse filtration system and a fine filtration system mounted on the host hanging plate. The water purifier is characterized in that: it also includes a full automatic control system, the bottom of the host hanging plate is provided with a one-piece cover correspondingly connected to the bottle mouths of filtration bottles, the one-piece cover is equipped with interfaces in butt joint with filtration bottle mouths and water flow channels in connection with each filtration bottle, the fine filtration system is provided with a booster pump and a low pressure switch, when the water pressure is higher than a set value of the low pressure switch, the system automatically starts to work, and a pure water outlet pipeline of the fine filtration system is provided with a high pressure switch, and according to whether the water pressure is higher than a set value of the high pressure switch, the control system stops working or starts to work. In the invention, filtration bottle covers are designed as the one-piece cover, the material cost and production cost are greatly saved, the assembling is very simple and fast, and sealing performance is good. The set full automatic control system is not only convenient and safety to use, but also helps timely mastery of the operation state of the whole machine and life condition of its filter core, as well as timely maintenance.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a pure water machine. Background technique [0002] The filtration system of the pure water machine is divided into a coarse filtration system and a fine filtration system. The filter element of the coarse filtration system is generally composed of three or more filter bottle groups. Each filter bottle group includes a filter bottle, filter material, sealing ring and filter bottle. Each filter bottle group is connected in series through quick connectors and PP pipes to form a complete coarse filtration system, and then it is fixed on the machine hanging plate through fixing pieces. This traditional structure is relatively complicated. The filter bottle cap needs to be connected and fixed by the fixing parts and the hanging plate. There are many processes, the assembly process is cumbersome and inconvenient, and the manufacturing cost is also high. Moreover, the metal part...

Problems solved by technology

This traditional structure is relatively complicated. The filter bottle cap needs to be connected and fixed by the fixing parts and the hanging plate. There are many processes, the assembly process is cumbersome and inconvenient, and the manufacturing cost is also high. Moreover, the metal parts are used as the hanging plate, which is prone to rust and rust after a long time. At the same time, this structure generally does not adopt automatic control, and the operating status of the whole machine and the life of the filter element cannot be directly displayed, so that the operating status of the machine cannot be grasped in a timely manner, and the filter element cannot be cleaned and maintained in time. Not conducive to the use and maintenance of the machine
