Technical Field
[0001] This utility model relates to the field of toilet deodorization technology, specifically to a deodorization device for toilets on high-speed trains. Background Technology
[0002] High-speed rail has different regulations in different countries and at different times. In order to facilitate the passenger experience, domestic high-speed rail is generally equipped with toilets. The toilets are usually located at the end of each carriage. Because the toilets on high-speed rail are in a closed space, the odors generated inside cannot be effectively dispersed.
[0003] Traditionally, a box of solid fragrance is placed inside the toilet. By rotating the top lid to create a perforated state, the fragrance diffuses and deodorizes the toilet. This method is convenient and quick. However, the fragrance is kept open for a long time, which greatly shortens its lifespan. It also leads to waste when the toilet is not in use. Furthermore, high-speed rail toilets are in enclosed spaces, which prevents the fragrance from diffusing quickly, significantly reducing their practicality.
[0004] Therefore, it is particularly important to improve the existing deodorization devices in high-speed train toilets and design a new type of deodorization device to solve the above-mentioned technical defects and improve the overall practicality of the deodorization devices in high-speed train toilets.
