Description

Technical Field

[0001] The utility model relates to the technical field of humidifiers, in particular to a humidifier with electrolytic disinfection function. Background Art

[0002] Sodium hypochlorite is a common disinfectant. It forms hypochlorous acid through hydrolysis, which further decomposes to form new oxygen. Hypochlorous acid can act on cell walls and virus shells. Because hypochlorous acid molecules are small and uncharged, they can also penetrate into bacteria (viruses) and react with organic macromolecules such as bacterial (viral) proteins, nucleic acids and enzymes to kill pathogenic microorganisms.

[0003] Chinese patent CN204923314U discloses a humidifier, including a shell and a base, and also includes a water tank, a titanium electrode, an automatic drain device, a disinfection pool, an atomizer, an air outlet, a mist exhaust channel and a mist exhaust port, wherein a water tank filled with saline is installed at the upper end of the shell cavity, two titanium electrodes are inserted into the saline solution and the top ends thereof are connected to a power source through a wire, the disinfection pool is installed at the bottom of the water tank and fixed above the base, the automatic drain device connects the water tank and the disinfection pool, the atomizer is arranged in the disinfection pool, the air outlet thereof is communicated with the mist exhaust channel located above the atomizer, and the mist exhaust port is installed at the top end of the mist exhaust channel and extends out of the shell.

[0004] This humidifier uses two titanium electrodes and saline solution to form a battery system, and electrolyzes hypochlorous acid, chloride ions and new ecological oxygen; the ultrasonic atomizer uses high-frequency electronic oscillations and the high-frequency resonance of the ceramic atomizer to break up the molecular structure of the disinfectant solution in the disinfection pool and produce a naturally floating disinfectant solution mist.

[0005] The above-mentioned prior art is provided with a relatively independent water tank and disinfection pool, a titanium electrode electrolyzes salt water in water, the water tank and the disinfection pool are connected by a drainage device, so that the hypochlorous acid solution in the water tank flows into the disinfection pool, and the atomizer atomizes the hypochlorous acid solution in the disinfection pool. The amount of hypochlorous acid solution in the disinfection pool is very small, accounting for only a very small part of the electrolyte in the water tank, and the effective disinfection gas consumed by the atomizer and the amount of volatilization are very small. More hypochlorous acid, chloride ions and new ecological oxygen react or volatilize again in the water tank, instead of generating disinfection solution mist to improve indoor air. The prior art has a complex structure, limited energy consumption conversion, and poor disinfection effect.

[0006] Therefore, the prior art still needs to be improved and developed. Utility Model Content
