Description

Deodorizing device for toilet Technical Field The utility model relates to the technical field of bathroom, in particular to a deodorizing device of a toilet. Background Most of the existing electronic toilets are provided with deodorizing systems to realize deodorizing function, and the deodorizing modes commonly used in the deodorizing systems at present comprise an adsorption mode and a water spraying mode, wherein the adsorption mode is a mode of adsorbing odor components in odor by adopting adsorption media (such as cold catalysts, diatom purity, active carbon and the like), and the water spraying mode is a mode of dissolving the odor components in the odor by adopting spray water. However, for adsorption type deodorization, a consumable material (adsorption medium) is required, the cost is high, the wind resistance is increased after the adsorption medium is arranged in the deodorization air duct, the deodorization efficiency is low, and for water spray type deodorization, a separate waterway special for deodorization is required, and real-time control is required, so that the structure and control are complex. In view of this, how to provide a deodorizing device for a toilet with simple structure, low cost and high deodorizing efficiency is a technical solution to be solved at present.
