Automatic water supply system used for steam sterilizer

Abstract

The present invention provides an automatic water supply system used for a steam sterilizer. The automatic water supply system comprises a water source water supply system for automatically pumping water, a water purification tank and a circuit board arranged in the steam sterilizer, the water purification tank is provided with a water level sensor, and the water level sensor is electrically connected with a first communication port arranged on the circuit board; the water source water supply system is connected with a pressure reducing valve and a water filtering device; the water filtering device is connected with two water supply pipelines; each water supply pipeline is also respectively provided with a solenoid valve electrically connected with the circuit board in the steam sterilizerand convenient for controlling opening and closing of the water supply pipelines, and the circuit board is provided with a second communication port electrically connected with the solenoid valves; through the water level sensor and the solenoid valves and under control of the circuit board, water is automatically added to the water purification tank; and automatic water filtration solves a waterquality problem of water supply by the sterilizer, besides, a fully automatic water supply function effectively solves a water supply problem of the sterilizer, and the automatic water supply systemincreases working efficiency of medical staff and saves costs of water supply.

Description

【Technical field】 [0001] The invention relates to steam sterilizer technology, in particular to an automatic water supply system for steam sterilizers. 【Background technique】 [0002] With the progress of society and the development of science and technology, the gradual improvement of economic level and material life, the concept of dental health has been paid more and more attention by people. More and more dental clinics and dental hospitals are located in cities. The dental clinics use The frequency of sterilization of surgical instruments is gradually increasing, and used instruments need to be sterilized by high-pressure steam sterilizers. [0003] In the prior art, the high-pressure steam sterilizer is provided with an electric heating tube, and the water in the steam generator is heated to generate steam through the electric heating tube. , the water level in the steam sterilizer gradually decreases. In the existing working mode of the steam sterilizer, the water le...

Problems solved by technology

[0003] In the prior art, the high-pressure steam sterilizer is provided with an electric heating tube, and the water in the steam generator is heated to generate steam through the electric heating tube. , the water level in the steam sterilizer gradually decreases. In the existing working mode of the steam sterilizer, the water level in the steam generator is added to the high water level before sterilization, and no water is added to the steam generator during the whole sterilization process. Internal water replenishment, the defect of this working method is that if the whole sterilization process takes a long time, the water level in the steam generator will be too low, which will affect the life of the heating tube in the steam generator, and even the heating tube will burn out or stop working
