Heating sterilizing device used on water drinking device

Abstract

The invention provides a heating sterilizing device used on a water drinking device. The heating sterilizing device is mounted between a base of a water outlet control electromagnetic valve and a water outlet nozzle fixing plate in a sealed manner, and the heating sterilizing device and the water outlet control electromagnetic valve are connected with a control mainboard of the water drinking device; the heating sterilizing device comprises a heating cavity, a metal heat conducting ring, a heating film, a temperature controller and a temperature sensor are arranged in the heating cavity, the metal heat conducting ring is butted to the upper end face of the heating film, a through hole superposed with a central hole of the metal heat conducting ring is arranged in the center of the heatingfilm, the temperature controller and the temperature sensor are butted to the lower end face of the heating film, and the heating film, the temperature controller and the temperature sensor are connected with the control mainboard. When the heating sterilizing device is started for sterilizing, the heating film is arranged on the bottom of the heating cavity, the heating film attaches to the bottom of the metal heat conducting ring, the heating film heats water in the cavity, the water after evaporating fills the whole passageway cavity and a water outlet nozzle, and thus a sterilizing effectis achieved.

Description

technical field [0001] The invention relates to a drinking fountain, in particular to a heat sterilization device used in drinking water equipment. Background technique [0002] Drinking water equipment is a machine that provides users with pure water, mineral water, or other beverages. It is similar to schools, businesses, or public places where people gather. It needs to be equipped with water supply equipment that can be used by many people. The environment for these public equipment is also extremely complicated. , The water outlet of its drinking water device is often connected to the atmosphere, which is easy to breed bacteria. [0003] At present, the main problem of the products on the market is that the total number of test bacterial colonies in the water taken from the outlet exceeds the standard, causing health damage to the human body. [0004] The water outlet solenoid valves on the market do not have a heating function, or when receiving hot water, put high te...

[0002] Drinking water equipment is a machine that provides users with pure water, mineral water, or other beverages. It is similar to schools, businesses, or public places where people gather. It needs to be equipped with water supply equipment that can be used by many people. The environment for these public equipment is also extremely complicated. , the water outlet of the drinking water device is often connected to the atmosphere, which is easy to breed bacteria

[0003] At present, there are major problems with the products on the market. The total number of test colonies in the water taken from the outlet exceeds the standard, causing health damage to the human body.

[0004] The water outlet solenoid valves on the market do not have a heating function, or when receiving hot water, put high temperature water to sterilize, and the sterilization effect of ultraviolet sterilization is average, and it cannot be guaranteed that it can be irradiated in every corner
