Negative pressure urinal

Abstract

The invention discloses a negative pressure urinal which comprises a pot-shaped urinal body, a flushing port for flushing the urinal body is further fixedly formed in the middle of the top end of theurinal body, and a urine receiving opening used for receiving urine is formed in the surface of the side wall of the urinal body and the sectional area of the urine receiving opening ranges from 10 cm<2> to 300 cm<2>; the shape of the urine receiving opening is similar to a circle shape; a semi-arc-shaped urine receiving guide plate is fixedly installed on the surface of the outer wall of the bottom of the urine receiving opening; a flushing opening is formed in the middle of the inner side of the semi-arc-shaped urine receiving guide plate, a water outlet spray head is embedded in the flushing opening, and an infrared sensor used for human body induction is embedded in the top of the water outlet spray head; the surface of the infrared sensor is covered with a waterproof cover, and a sealing cover is fixedly installed at the top end of a damping hinge. According to the scheme, under the negative pressure of the draught fan, urine, odor and final residual urine can be sucked into the urinal, and the urination organ can be flushed and blow-dried; and meanwhile due to the three odor treatment modes, the negative pressure urinal has higher flexible selectivity and practicability in the actual use and installation process.

Description

technical field [0001] The invention relates to the technical field of urinals, in particular to a negative pressure urinal. Background technique [0002] Urinals are mostly used in toilets in public buildings. Some families also have urinals in their bathrooms. According to the structure, it is divided into: wash-down type and siphon type. According to the installation method, it is divided into: bucket type, floor type and wall type. [0003] 1) In the current existing urinals, during urination, due to the unpleasant smell in the urine, when the user urinates, the peculiar smell diverges upwards and is smelled by the nasal cavity, and the unpleasant smell pollutes the surrounding environment. Due to the open design of the traditional urinal urine connection, the urine is easy to splash on the urinator, which cannot play a good blocking role, and the urine and gas cannot be separated and filtered; [0004] 2) Existing urinals are inconvenient to carry out urinalysis for...

AI Technical Summary

Problems solved by technology

[0005] In the current urination process of the present invention, the urine contains relatively unpleasant peculiar smell, which is not convenient for negative pressure suction of gas. When the user urinates in the existing urinal, the peculiar smell diverges upwards and is smelled by the nasal cavity, and the peculiar smell is unpleasant Pollution of the surrounding environment, due to the open design of the traditional urinal urine connection when urinating, the urine is easily splashed on the urinator, which cannot play a good blocking role. The diversion of urine and gas cannot be achieved by providing a A kind of negative pressure urinal, to solve the problem that the urine contains relatively unpleasant peculiar smell in the current existing urination process proposed by the above-mentioned background technology and is not convenient for negative pressure suction treatment
