Background

Because of convenient use, the toilet bowl becomes the necessity of most families and many units. During the use of the toilet bowl, the whole toilet space is inevitably filled with odor due to the odor of human excrement. The simple deodorization method is to exchange air through a top exhaust fan or an exhaust fan, and the professional deodorization comprises fresh air deodorization, air circulation deodorization, space reaction deodorization and the like. The essence of the methods is air exchange and deodorization, and the air exchange and deodorization mode usually needs a period of time to be realized, the period is directly related to the ventilation volume of the exhaust air, the number of air exchange cycles is generally specified to be more than 3, the larger the ventilation volume is, the smaller the period is, but the larger the corresponding energy consumption is. In addition, a simple deodorization method is performed by a dilution method (except that the deodorization part is provided with an odor treatment device), namely, odor is directly discharged into the air, and the surrounding air environment is influenced to a certain extent. Whereas professional deodorization requires a more complicated odor purification device. Therefore, the in-situ deodorization technology and method are needed to be developed, so that the odor is reduced to the greatest extent and the air quality in the toilet is affected, and the toilet environment quality is improved.
