Embodiment 1

[0040] A deodorizing floor drain core, comprising an outer tube 1 and an elastic inner core 2.

[0041] The top of the outer tube 1 is provided with a first water inlet 3, and the side wall of the outer tube 1 is provided with more than one first water outlet 4, and the bottom of the outer tube 1 is closed.

[0042] The elastic inner core 2 is embedded in the first water inlet 3 of the outer tube 1, and the top of the elastic inner core 2 is fixedly connected with the top of the outer tube 1; The top is provided with a second water inlet 5, and the bottom of the elastic inner core 2 is provided with a second water outlet 6; the upper edge of the second water outlet 6 is lower than the lower edge of the first water outlet 4; The lower edge of the second water outlet 6 is higher than the bottom surface of the outer tube 1; a water flow channel is formed between the second water outlet 6 and the first water outlet 4; after water injection, the water flow channel forms a water sea...

Embodiment 2

[0063] see figure 2 As shown, the others are the same as the first embodiment, the difference is that a grid 16 is fixedly connected to the first water outlet 4 . The grid 16 is made of stainless steel and integrally formed with the outer tube 1 . When the elastic inner core 2 ages and falls off, the grid 16 can prevent the elastic inner core 2 from rushing into the sewer with the water flow, causing the sewer to be blocked.

Embodiment 3

[0065] see image 3 As shown, the others are the same as the first embodiment, except that a duckbill valve 17 is formed at the second water outlet 6 . Described duckbill valve 17 is prior art.

[0066] As an optional embodiment, a thin-walled corrugated structure can also be formed at the second water outlet 6. The thin-walled corrugated structure is a prior art. For details, please refer to the patent application number "201220052463.9", and the patent name is The technical scheme disclosed in the Chinese patent of "high drainage and deodorant floor drain core".

Abstract

The invention discloses a deodorization floor drain core. The deodorization floor drain core comprises an outer pipe and an elastic inner core, wherein a first water inlet is formed in the top end of the outer pipe, a first water outlet is formed in the side wall of the outer pipe, and the bottom of the outer pipe is closed; an elastic inner core is embedded in the first water inlet of the outer pipe, and the top of the elastic inner core is fixedly connected with the top of the outer pipe; a second water inlet is formed in the top end of the elastic inner core, and a second water outlet is formed in the bottom of the elastic inner core; the upper edge of the second water outlet is lower than the lower edge of the first water outlet; the lower edge of the second water outlet is higher than the bottom surface of the outer pipe; and a water flow channel is formed between the second water outlet and the first water outlet. The deodorization floor drain core has the characteristic that the soft elastic floor drain core can be prevented from falling off to block a sewer line.

Description

technical field [0001] The invention relates to the technical field of floor drain device manufacture, in particular to an odor-proof floor drain core. Background technique [0002] In the prior art, the Chinese patent with the patent application number "201220175840.8" and the patent title "Odor-proof Floor Drain" discloses a technical solution for floor drain deodorization, which has the technical effect of preventing sewer odor. But in actual use, there are two problems to be solved: [0003] (1) In this technical solution, the duckbill valve is set on the bottom of the inner tube and is made of elastic material. After using for a period of time, with the aging of the elastic material and the impact of the water flow, the duckbill valve may fall off; (usually alkaline sewage) to make it age faster and loosen more easily; [0004] (2) In this technical solution, the duckbill valve is installed at the lower end of the inner pipe and is located deep in the floor drain. Wh...
