Flush-proof filtration apparatus for vertical urinal

Abstract

A flush-free water filter device for a vertical urinal, comprising an outer box body (1), an overflow pipe (2) and an inner box body ( 3); the bottom (31) of the inner box body (3) has a water leakage hole (31a) and leaves a distance between the bottom of the outer box body (1), and the bottom of the inner box body (3) ( 31) is provided with a filter particle layer (5), and an oil seal layer (7) is provided above the filter particle layer (5); the overflow pipe (2) is located outside the inner box body (3), and its upper end is open to the outside In the inner cavity of the box body (1) and higher than the filter particle layer (5), its lower end is directly opened outside the outer box body (1); the upper part of the outer box body (1) is covered with a cover (8 /8'), the cover (8/8') is provided with a water leakage hole (81) or a water inlet pipe (81') at a position corresponding to the inner box body (3/3). The oil seal layer of the present invention is blocked by the filter particle layer and the bottom of the inner box body, so it will not be washed away or lost even under the impact of a water flow with a certain momentum, and it will always float on the inner box body under the action of buoyancy. The surface of the retained urine, thereby preventing the retained urine from being oxidized by the air and escaping the odor.

Description

technical field [0001] The invention relates to sanitary equipment for toilets, in particular to a flush-free water filter device for vertical urinals. Background technique [0002] At present, vertical urinals are widely used in toilets or public toilets in various public places. Traditional vertical urinals are all flush type, and the lower part of the body has a water outlet and is connected with the sewer pipe. If the foreign matter is blocked, the outlet hole is generally covered with a filter cover; generally, the sewer pipe has a U-shaped elbow part to preserve a certain amount of water as a water seal to isolate the turbid air in the sewer. Because the urine will produce bad smell after being oxidized by air, so the vertical urinal is generally also equipped with an automatic or manual flushing device, which is used for flushing after defecation. However, the water stored in the U-shaped elbow part is still urine. After being oxidized by air, the mixture of liquid a...
