Description

Technical Field

[0001] The present application relates to the technical field of pet feces deodorization, and in particular to a pet toilet sterilization and deodorization system. Background Art

[0002] Data shows that there are about 160 million pets in the country. Because pets are kept at home, they defecate every day in an indoor environment where humans live together. Pet feces contain sulfide ammonia and other substances, and their feces are smelly. At present, there are many traditional deodorants or ozone deodorization equipment on the market, but they cannot fundamentally solve the problem of pet feces odor. In summer or winter, when the air conditioner is turned on indoors and the doors and windows are closed, the stench of pet feces is a headache for people. Some people also connect the pet toilet to the external exhaust duct to directly discharge the stench of pet feces to the outside, but it also discharges the indoor air conditioning or heating, which not only increases energy consumption, but also causes the room temperature to not meet the standard.

[0003] Pet toilets have the problem of emitting foul-smelling gases and breeding bacteria, and there is currently a lack of effective treatment methods. The traditional purification method of ozone oxidation technology has residual ozone, which is very likely to cause secondary pollution to the indoor environment; excessive concentrations of ozone are not only harmful to adults, but also cause physical harm to children and animals; deodorants or deodorizing additives can only alleviate some of the foul-smelling gases, and cannot fundamentally solve the complex composition of pet feces odorous gases. Traditional deodorizing equipment is large in size and has high maintenance and consumables costs, resulting in high operating costs, but the purification efficiency is not high. The problem of deodorizing the foul-smelling gas from pet feces needs to be solved urgently. Summary of the invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a pet toilet sterilization and deodorization system.
