Description

Chlorine dioxide sustained-release gel device for toilet and sterilization toilet lid thereof

Technical Field

The invention belongs to the field of bathrooms, and particularly relates to a chlorine dioxide slow-release gel device for a bathroom and a sterilization toilet lid thereof.

Background

Along with improvement of living standard and the reinforcing of environmental protection consciousness, people attach more and more importance to the disinfection deodorization among the life of house, the bathroom is the facility that family life is indispensable, its inside health is mainly disinfected through spraying all kinds of antiseptic solutions or other toilet cleaning liquid, and because there is the dead angle inside the bathroom, utilize disinfection forms such as antiseptic solution, often can omit the dead angle part, cause the disinfection thoroughly, it is long-lived, the bacterium constantly breeds in the dead angle, make smell in the bathroom bad, and the spore of some bacterium can disperse in the bathroom, bring harm for the user. In the prior art, the toilet is disinfected and sterilized by using active carbon or an ultraviolet lamp. The active carbon has strong adsorbability, can adsorb impurities such as dust in the air, and has a purifying effect on the air. But the effect is single, and the sterilization effect can not be achieved. The ultraviolet lamp is also a commonly used sterilization and disinfection device, which is mainly used for ultraviolet sterilization, but the ultraviolet lamp sterilization can only kill places irradiated by ultraviolet light, and the sterilization effect is not good for cabinets with articles stored. In addition, ultraviolet exposure of the skin is prone to skin aging, presenting a risk of leakage. The fabric, especially silk fabrics, can be damaged by ultraviolet rays, the color of clothes is damaged, and especially high-grade clothes cannot be exposed to strong light. Chinese patent (application No. CN202020366929.7) provides a special oxygen ion sterilization and deodorization instrument for toilets, which comprises a sterilization and deodorization instrument main body and a base, wherein the sterilization and deodorization instrument main body is installed above the base, and the sterilization and deodorization instrument main body comprises a shell, an air inlet, a gas processing device, a battery, an oxygen ion generator, a fan and an air outlet. The sterilizing device in the patent needs to be provided with a battery for use, can be used only in an electrified state, has a complex structure and high cost, and has great use limitation.

Chlorine dioxide is the only A1 grade safe and high-efficiency disinfectant jointly identified by the world health organization and the food and agricultural organization of the United nations, and is the internationally recognized safest disinfectant. During the disinfection and sterilization process, the chlorine dioxide reacts with amino acid to make virus protein lose biological activity; it can also react with cell membrane protein to kill bacteria. Therefore, the chlorine dioxide has the characteristics of broad spectrum, high efficiency and high speed in the disinfection mechanism, does not generate drug resistance, is harmless to human bodies in the using process, has no side effects of carcinogenesis, teratogenesis, mutagenesis and the like, and belongs to a disinfectant capable of being used for a long time. Many foreign research results show that chlorine dioxide can kill many pathogenic bacteria such as escherichia coli, staphylococcus aureus and the like at an extremely low concentration (0.1 ppm). Even if the microorganism is interfered by organic substances, the microorganism can be completely killed when the concentration is tens of ppm. Therefore, chlorine dioxide is a safe and efficient air sterilization and disinfection purifying agent universally accepted by the society. The existing commonly used chlorine dioxide disinfectant is liquid after being prepared, and because the chlorine dioxide volatilizes fast and cannot be placed for a long time, the existing preparation is needed, the operation is relatively complicated, and the disinfection effect is not durable enough.
