Water supply device capable of controlling water level accurately

Abstract

A water supply device capable of controlling water level accurately comprises a water feeding pipe, a water discharge pipe and a water tank; the water tank is connected with the water feeding pipe and the water discharge pipe and is internally provided with a water level control valve subassembly; the water level control valve subassembly comprises a cavity internally provided with a sealing gluepad, a floating tube and a supporting pillar; the water pressure area at the bottom of the sealing glue pad is greater than that of the upper plane thereof; the sealing glue pad can be moved upwards and downwards by means of the pressures of upper and lower water; the supporting pillar is fixed above the floating tube; a release hole is formed at the bottom of the valve cavity at the position corresponding to the supporting pillar; a water inlet and a water outlet are formed on the valve cavity, and the water inlet is connected with the water feeding pipe. The device has simple and skilful design, accurate liquid level control effect, less stored water and highly accurate water feeding effect. The product by using the design of the device can be ultra-minimized and thinned. The raw material can be saved a lot, the cost can be reduced, and the product reliability is high. The invention can be widely applied to the product with water level to be controlled such as water boiler and waterdispenser, thereby having great social and economical benefits.

Description

technical field [0001] The invention relates to the technical field of water level control, and more specifically relates to a precision water level control water supply device applied to products that need to have an automatic control water supply function. Background technique [0002] Water level control devices are widely used. In water supply systems such as industry and daily life, there are many occasions where it is necessary to monitor the liquid level and automatically control the replenishment of the liquid level medium, such as the water supply device of the electric water boiler commonly used in people's daily life. Water is an indispensable substance for people to maintain life. Normal people need to drink 2 liters of water a day to ensure the basic needs of a healthy life. With the improvement of material living standards, boiled water can effectively kill various harmful microorganisms. Therefore, in In public places such as factories, schools, companies, off...
