Description

Fresh air purifier for public toilet

Technical Field

The utility model belongs to air purification equipment, concretely relates to new trend clearing machine is used in public latrine.

Background

The space of public lavatory is airtight, exists stink and other peculiar smells on the one hand easily, breeds the bacterium on the other hand easily. In order to solve the above problems, a current solution is to use incense, but the incense has a strong taste, easily generates smoke to make people feel uncomfortable, and cannot completely remove odor. Another solution is to set up a special drainage system to use a large amount of water to wash, which wastes a large amount of tap water on one hand and produces a large amount of sewage on the other hand, causing a great burden to the water used in the city.

The toilet peculiar smell is difficult to effectively solve at present, the main reason is that excrement and urine are simultaneously used as excrement, and the characteristic difference corresponding aiming at the excrement and urine is not provided: the excrement just discharged is not stink actually because a layer of mucosa on the surface completely wraps components such as indole and skatole which can give off strong stink, and the excrement falls into a urinal or water under the action of gravity after being separated from a human body to destroy a protective film, so that bacteria and decomposition products in the excrement are diffused into the air to generate stink, and the flushing is carried out after the stink is volatilized, so that the stink of the excrement cannot be completely eliminated.

Compared with the excrement with the odor-causing factor, the urine has no odor, and research data show that: human urine contains a large amount of nutrients such as nitrogen and phosphorus, and nitrogen element in the urine of a human body which is just discharged mainly exists in the form of urea, and phosphorus element mainly exists in the form of polyphosphate, so that the urine generates odor because the urine splashes outside a urinal and the urine remained at the edge of the urinal is dried and then chemically reacts with oxygen, and therefore the odor generated by the urine cannot be completely eliminated by flushing.
