Filled with clean water, so the odor, skatole, hydrogen sulfide and ammonia in the odor will not re-diffuse into the air, and will not remain in the purification device, so it will not affect the next purification effect. It also does not need to clean and maintain the deodorizing device, fundamentally eliminate the odor in the bathroom and improve the environment in the bathroom.
- the invention utilizes water to purify and deodorize, does not have a chemical reaction, and has no by-products, and does not affect the external environment while removing the odor of the bathroom, and is beneficial to the improvement of the overall environment.
- the entire purifying mechanism 30 is placed in the toilet or the water tank 10, and no external equipment, pipelines, etc. need to be paved on the outside, and standardized equipment can be formed, which is popularized and applied, and has broad market prospects.
