Stink-leaking prevention device and floor drain with stink-leaking prevention device thereof

Abstract

The invention discloses a stink-leaking prevention device, which includes a water draining pipe and a diversion cover. The lower end of the water draining pipe is bended towards the inner part and towards the upper part in the axis direction to form a water collecting pipe; the upper end of the water collecting pipe is provided with a sealed plate, a plurality of water draining holes are formed inthe lateral wall of the water collecting pipe, a water collecting cavity is formed between the space of the external wall of the water collecting pipe and the internal wall of the water draining pipe, and internal holes of the water collecting pipe are water outlet poles; and the diversion cover is installed on the sealed plate, and free ends of the diversion cover are mounted in the water collecting cavity. According to the stink-leaking prevention device, the function of the stink-leaking prevention is better achieved, and at the same time, the speed of water draining is greatly improved. The invention further discloses a floor drain with stink-leaking prevention device.

Description

technical field [0001] The invention belongs to the technical field of drainage, and in particular relates to an anti-odor device. The invention also relates to a floor drain with an anti-odor device. Background technique [0002] The anti-odor floor drain is an important interface connecting the drainage pipe system and the indoor floor. As an important part of the drainage system in the residence, its performance directly affects the quality of the indoor air. It is very important for the odor control in the bathroom. Now most families choose to use it Odor-proof floor drain. [0003] The existing deodorant floor drains on the market, such as figure 1 As shown, it usually includes a water storage pipe 101 and a water collection pipe 102. The water storage pipe 101 is U-shaped. The water collection pipe 102 is inserted in the water storage pipe 101 and the bottom of the water collection pipe 102 points to the bottom of the water storage pipe 101. In the sewage pipe 103, ...

[0003] The existing deodorant floor drains on the market, such as figure 1 As shown, it usually includes a water storage pipe 101 and a water collection pipe 102. The water storage pipe 101 is U-shaped. The water collection pipe 102 is inserted in the water storage pipe 101 and the bottom of the water collection pipe 102 points to the bottom of the water storage pipe 101. In the sewage pipe 103, several water outlets 104 are provided on the side of the water storage pipe 101. During use, water storage is formed in the water storage pipe 101, thereby sealing the bottom of the water collection pipe 102 to achieve the purpose of deodorization. However, this In the anti-odor floor drain of this structure, the distance between the outer wall of the water storage pipe 101 and the inner wall of the sewage pipe 103 determines the drainage speed of the anti-odor floor drain, because the water is discharged from the water outlet 104 on the side of the water storage pipe 101, and the diameter of the sewage pipe 103 in China Smaller, and the fixed value of the pipe diameter is a uniform standard. In order to obtain a better launching speed, the pipe diameter of the water storage pipe 101 is usually made as large as possible, which can make the inner diameter of the water collection pipe 102 larger, thereby improving Drainage speed, however, this design method will make the drainage speed slow down instead, because the gap between the outer wall of the water storage pipe 101 and the inner wall of the sewage pipe 103 becomes smaller

In addition, when used for a long time, due to the small space between the water outlet 1 and the inner wall of the sewage pipe, human hair is easy to accumulate at the water outlet 104, resulting in blockage
