The odor in school toilets is generally composed of harmful gases such as hydrogen sulfide, methane, and ammonia. In a foul smelling environment, the odor can stimulate the human senses. In most people's consciousness, the odor seems to have little effect on the human body. When they smell the odor, they can hold their nose and endure it for a while before it passes. This viewpoint is incorrect. When your nose smells a foul odor, it is actually a warning from your sense of smell, telling you that the surrounding environment and air are not good for your body and wanting you to stay away. Odor can stimulate human senses, affect physical health and learning mood, leading to a decrease in learning and work efficiency for students and teachers. Especially in summer, there are at least over 50 types of diseases transmitted through flies. It can be said that they pose a long-term threat to students and teachers.

At present, most of the methods for deodorizing public toilets in schools are air masking or using exhaust fans to remove odors from the toilets, each of which has its own significant drawbacks. The air masking method, which is a way of deodorizing, seems too self deceptive. Although air fresheners mask odors, harmful substances are still inhaled into people's bodies in the air; When using an exhaust fan to extract air, the turbid gases and substances on the ground will also be sucked out, causing greater harm than before.

The deodorization and sterilization machine developed by Tongbao Environment is designed with five levels of purification, with an overall odor removal ability of over 90% and a sterilization rate of 95%. Independent intellectual property rights, pioneering patented technology for deodorization and sterilization without consumables, creating an era of constant clean air in public toilets.
