UV water-filter control device and water pressure switch group

Abstract

The invention relates to a control device of an ultraviolet water filter and a hydraulic pressure switching group, wherein, the control device is arranged in a water inlet seat below the water filter, and is provided with a water inlet channel, and the water inlet channel is equipped with a by-pass port for connecting with the mechanical hydraulic pressure switching group, when water passes through the water inlet channel to enter the water filter, the hydraulic pressure switching group can be synchronously switched on to start up an ultraviolet lamp in the water filter to send out ultraviolet rays for sterilization, and when the water stops flowing, the hydraulic pressure switching group can delay the closing time of the ultraviolet lamp, and fully sterilize the residual water in the water filter.

Description

【Technical field】 [0001] The invention relates to an ultraviolet water filter control device and a water pressure switch group, in particular to a control device for automatically controlling the UV light tube in the water filter to start or close the sterilization program by means of a mechanical water pressure switch group. 【Background technique】 [0002] No matter how modern a city you live in, its water supply system must go through complex small reservoirs, pressurization stations, and pipelines before it can be distributed to every user; and during the operation of the water supply system, it may be due to Old pipes, leaks, public works construction or dirty reservoirs and other factors are polluted, so that the water obtained by users usually contains impurities and E. coli. It must be filtered and boiled before drinking, otherwise it may Cause symptoms such as gastrointestinal discomfort. [0003] In order to solve the problem of drinking water, various water filter...

AI Technical Summary

Problems solved by technology

The main reason is that the simple digital circuit is easily disturbed by static electricity or magnetic field and malfunctions, and a water flow detector (water flow switch) must be installed at the water inlet or outlet, but because the general water flow detector cannot be adjusted The sensitivity of water pressure often fails to sense the action

When the user opens or closes the water valve, the water flow detector provides an open or close signal to the control circuit for related start-up and delayed closing control; in other words, if the water flow detector is damaged, poor contact, etc. In case of abnormal conditions, it will affect the normal shutdown or shutdown of the ultraviolet lamp. In addition, related delay electronic components such as capacitors, electricity, timing devices, etc., most of them cannot resist electromagnetic interference in use, so that the overall delay circuit will still have Misoperation occurs
