Chinese people have a habit of drinking hot water which is cooled to a proper temperature after being boiled. Drinking hot water has many advantages, such as maintaining gastrointestinal health, improving blood circulation of the body, preventing and treating cold, etc., and hot water can also be used for making tea, making milk powder, etc. At present, the main method for obtaining hot water with a certain temperature is to boil the water and then cool the water, or directly mix cold water with the water. The popularity of the counter-top water boiler has brought another way to obtain hot water, i.e. cold water is directly heated to a certain temperature by a heating body and a temperature control sensor and then directly drunk. Direct heating to a certain temperature presents health risks due to the absence of boiling water, or secondary pollution. Promoted by commercial market and mother and infant market, boiled earlier, the water purification unit of reuse cold water heat transfer cooling or with the compressor cooling to the warm water receives consumer's favor gradually. At present, a plurality of commercial water purifying devices are provided with modules for obtaining warm boiled water through heat exchange, some household mother and infant water purifiers also adopt similar devices to prepare warm boiled water, and the market of warm boiled water also gradually begins to be popular.

The warm water equipment has the important function of killing bacteria and other microorganisms at high temperature and then quickly obtaining hot water which can be directly drunk. However, in the real environment, when the warm water apparatus is left for a while after being used once, the sterilization substances in the water are destroyed by the filtering system or the heating process, and the warm water environment is very favorable for the propagation of microorganisms. The domestic warm boiled water system is influenced by factors such as volume, cost and the like, the heat exchange module is communicated with the water outlet nozzle, no partition part is arranged, the water outlet nozzle is exposed in the atmosphere, and when the equipment is not used, microorganisms in the air can enter the heat exchange module through the water outlet nozzle and breed in the heat exchange module.

Therefore, the requirements of re-sterilization exist for warm boiled water flowing out of the existing warm boiled water equipment.
