Water purifier controller

Abstract

The invention relates to a water purifier controller, which comprises a singlechip, a pulse signal receiving module, an ultraviolet lamp driving module, a display module and an alarming module, wherein the singlechip is preset with a total volume of water that a corresponding filter element can filter and the total disinfecting time of an ultraviolet lamp; the pulse signal receiving module is used for receiving a pulse signal generated on an impeller and sending the information to a pulse signal receiving module of the singlechip; and the ultraviolet lamp driving module is used for receiving a control signal sent by the singlechip to drive the ultraviolet lamp on a water purifier to open or close. The controller realizes the visual display of the service conditions of the filter element and the ultraviolet lamp of the water purifier and monitors the water flow of the water purifier and the service life of the filter element and the ultraviolet lamp an any time, thereby ensuring that a water source can be drunk safely after being filtered and sterilized.

Description

technical field [0001] The invention relates to a controller for controlling the use state of a water purifier. Background technique [0002] We know that most of the tap water that is usually supplied has been bleached and is generally not suitable for drinking directly. If you want to drink it, you need to boil it. Even if you use bottled pure water or mineral water, it has a certain shelf life (about 30 days), and it is easy to breed bacteria and pollute the water quality. In order to solve the problem of drinking water safety, many water purifiers appear on the market. Generally, the water purifier adopts the principle of reverse osmosis, and the filtration accuracy reaches 0.0001 microns. The principle of water purification is to gain and lose electrons, not a simple membrane to screen large impurities. It should be said that such a technology has no problem in removing bacteria, viruses, E. coli, etc. It can be drunk completely raw; the filtration methods of water pu...

Problems solved by technology

However, the filter element or ultraviolet lamp has a limited service life. When the filter element filters a certain amount of water or the ultraviolet lamp is turned on for a certain period of time, the filtering or anti-virus effectiveness is greatly weakened, or even lost.

However, the water purifiers on the existing market lack the detection of the total water volume filtered by the filter element, and only replace it at a fixed end time; this cannot effectively ensure the quality of the filtered water

There is also no control and detection of the use time of the ultraviolet lamp, so the effective disinfection and sterilization of the water purifier cannot be guaranteed after it has been used for a period of time
