Device for detecting water level in water purifier or water boiler

Abstract

The invention discloses a device for detecting a water level in a water purifier or a water boiler. The device comprises a tap water three-way valve, a pressure water storage tank and a second rear activated carbon, wherein a PP cotton filtering barrel is arranged on a left side of the tap water three-way valve; a flow meter is mounted on the left side of the PP cotton filtering barrel; a high-pressure water pump is arranged on the left side of the flow meter; a water inlet electromagnetic valve is mounted on the left side of the high-pressure water pump; an anticorrosion layer is fixed on aninner wall of the pressure water storage tank; the pressure water storage tank is located below a pressure barrel ball valve; a purified water faucet is mounted on the left side of the second rear activated carbon; and the second rear activated carbon is located on the left side of first rear activated carbon. A method for detecting the water level in the water purifier or the water boiler adoptsan MEMS silicon wafer pressure sensor, has high precision and good degree of linearity, has a water pressure difference of up to 1 mm, namely a water error of smaller than 0.1 L, continuously controlsthe water level, and can accurately control the water level according to water consumption of customers, so as to save energy and protect environment.

Description

technical field

[0001] The invention relates to the technical field of water purifier devices, in particular to a water level detection device in a water purifier or a water boiler. Background technique

[0002] Water plays the main role in the water purifier or water boiler, so the monitoring of water is very important. Inside the water purifier, such as the pressure tank, the internal water level line needs to be strictly controlled, otherwise it will easily cause the internal water pressure of the pressure tank to be low. As a result, the water supply is not timely. There are many ways to observe the water level in modern times. The most common method is to use a ruler to monitor the water level, whichever is visible to the human eye.

[0003] The existing water level detection is segmented, the entire capacity is divided into several points, which is imprecise and cannot accurately set the water level according to the customer's water consumption. It can only be divided ...
