Description

technical field [0001] The invention relates to a device in the technical field of daily necessities, in particular to a regenerative toilet adsorption deodorization device. Background technique [0002] In large shopping malls, supermarkets, railway stations, bus stations, large exhibition halls and other public places with a large flow of people, public toilets often have very serious odors. At the same time, public toilets generally adopt mechanical ventilation, which directly discharges the odor of the toilet through the air outlet, which also has an impact on the outdoor environment. There are also public restrooms that use odor coverage, that is, using solid flavoring agents to emit certain fragrances in public restrooms to cover the odor, but the mixture of fragrance and odor still makes the bathroom smell even worse.

Problems solved by technology

[0003] After searching the literature of the prior art, it is found that the Chinese utility model patent name is: air deodorization and sterilization device for public toilets, and the application number is: 200720190181.4. This patent discloses a deodorization and sterilization device for public toilets. A liquid storage tank with deodorizing and bactericidal agents is installed in the public toilet, and a series of operations such as a lift pump, a low water level protector, a high water level protector, an atomizer box and a fan in the liquid storage tank are used to achieve deodorization. The purpose of odor sterilization, but considering that the deodorant bactericide itself has a certain impact on people, and the device is complicated and the cost is high, the problem of toilet ventilation and exhaust is not considered
