Problems solved by technology

[0005] Most electric water boilers need to have a water shortage protection function. Considering various reasons such as cost and structure, the problem of water inflow should be solved at the same time; Water protection function; the electrode and logic circuit used in the water boiler that uses the principle of water resistance to control the water inlet of the solenoid valve use the control mode to detect the water level and control the heating, but it is difficult to adapt to the high temperature and high humidity environment, poor reliability, and high maintenance rate. very popular

Embodiment 1

[0043] like figure 1 Shown is the universal water inlet valve for the temperature-controlled electric water boiler and the boiling water turning electric water boiler, which includes two functions of automatic water inlet and water shortage protection; figure 1 The pressure-sensitive limit water inlet valve and water shortage protection shown are installed at the specified height at the bottom of the water boiler furnace (relative to the water level requirements in the furnace), and the spring preload and the micro switch B1 for water shortage protection are adjusted. The action point can meet the water level control and water shortage protection requirements of all water boilers.

Embodiment 2

[0045] like Image 6 shown in figure 1 On the basis of removing the micro switch B5, the remaining part can be used as a pressure-sensitive limit water inlet valve for ordinary water tanks; adjusting the spring preload can meet the water tank inlet water level control requirements.

[0046] Its specific structure is as follows:

[0047] A pressure-sensitive limit water inlet valve is characterized in that it includes a template assembly A installed between the disc-shaped upper valve housing 1 and the disc-shaped lower valve housing 2,

[0048] The template assembly A includes a rubber template A1, a pair of splints A2 and a guide pin A5, the rubber template A1 is a disc-shaped structure, and is provided with arc-shaped circular folds A11 near the edge, and the folds A11 Protruding upwards, the disc-shaped splint A2 is clamped on the upper and lower sides of the rubber formwork A1. The diameter of the splint A2 is smaller than the diameter of the circular fold A11. The rubbe...

Abstract

A voltage-sensitive limit water inlet and water shortage protective device comprises a template assembly installed between an upper dish-shaped valve shell and a lower dish-shaped valve shell. A closed space formed between the lower dish-shaped valve shell and the template assembly is communicated with a water storage cavity of a water boiler through a pipe base. A space formed between the upper dish-shaped valve shell and a rubber template is communicated with the atmosphere. A guide ejector rod between the rubber template and the upper dish-shaped valve shell is used for controlling a microswitch. The pipe base is provided with a tee valve body, a valve plug assembly controlling the tee valve body for water feeding is installed in the tee valve body, and the valve plug assembly is connected with the lower end of the template assembly. The voltage-sensitive limit water inlet and water shortage protective device further comprises the microswitch controlled by the guide ejector rod. The voltage-sensitive limit water inlet and water shortage protective device does not need to be installed on the water surface, is not supported by water level detection or a logic circuit, does not occupy the height space of a boiler furnace area of the water boiler, and fully integrates the water inlet protection and water shortage protection functions of an electric heat water boiler, the problem of water shortage protection does not need to be solved independently, and the voltage-sensitive limit water inlet and water shortage protective device is simple in structure, stable in performance, high in adaptability and low in cost, and is a water inlet valve applicable to various electric heat water boilers and water tanks.

Description

technical field [0001] The invention relates to a pressure-sensitive limiting water inlet and water shortage protection device for a water boiler, which is used for controlling water inlet and water level of a water boiler or a water tank and providing a water shortage protection signal. Background technique [0002] The water inlet and water level control and water shortage protection of fully automatic electric water boilers have always been the core issues that have plagued the research and development personnel of electric water boilers; on the one hand, the float-lever water inlet valve in the early years often leaked water, which caused the water boiler to often produce yin and yang water. It is unfavorable to the health of the drinker; in addition, the float-lever water inlet valve requires a large water tank installation space and a specific installation height requirement inside the water boiler, which seriously limits the shape and structural design of the electric ...
