Description

Deodorant floor drain core

Technical Field

The invention relates to the technical field of manufacturing of floor drain devices, in particular to a deodorant floor drain core.

Background

In the prior art, Chinese patent with patent application number of '201220175840.8' and patent name of 'deodorant floor drain' discloses a technical scheme for deodorizing floor drain, and has the technical effect of preventing the smell of sewer. However, in practical use, there are two problems to be solved:

in the technical scheme, the duckbill valve is arranged at the bottom of the inner tube and is made of an elastic material. After a period of use, the duckbill valve has the potential to fall off as the elastomeric material ages and the water stream impinges; moreover, the duckbill valve sleeved at the bottom of the inner tube is contacted with sewage (usually alkaline sewage) accumulated at the bottom of the outer tube for a long time, so that the duckbill valve has higher aging speed and is easier to loosen;

(II) in this technical scheme, the duckbilled valve is installed at the inner tube lower extreme, is located the floor drain depths, when appearing closing untight or when breaking off the equal trouble, the user can not discover directly perceived usually and in time handle, only when the user pulls out this problem can be discovered when the inner tube.

Compared with the technical scheme disclosed in the Chinese patent with the application number of '201220175840.8', the technical scheme has the advantages that: according to the technical scheme, the metal inner tube of the deep water seal floor drain core is improved into the silica gel elastic floor drain core, and the silica gel elastic floor drain core can more fully utilize the space above the first water outlet 4 in the outer tube 1. After improvement, the sewage capacity in the upper section core 13 is larger, so that the water pressure at the second water outlet 6 of the elastic inner core 2 is larger, and the drainage speed is higher. Meanwhile, the elastic inner core 2 can also play a role of a sealing ring to seal a gap between the elastic inner core 2 and the outer tube 1.

In this embodiment, the second water inlet 5 is located at the top end of the upper core 13, the second water outlet 6 is located at the bottom end of the lower core 14, and the top end of the lower core 14 is connected to the bottom end of the upper core 13 through the connecting core 15. The inner diameter of the elastic inner core 2 is wide at the top and narrow at the bottom, and the inner diameter of the upper section core 13 is larger than the inner diameters of the connecting 15 core and the lower section core 14. The outer diameters of the connecting core 15 and the lower section core 14 are smaller than the inner diameter of the outer pipe 1, and after the connecting core 15 and the lower section core 14 are assembled, a water passing channel is formed between the outer side surfaces of the connecting core 15 and the lower section core 14 and the inner side surface of the outer pipe 1. The connecting core 15 and the lower section core 14 do not block the first water outlet 4 from discharging water.

When the water is not drained, the second water outlet 6 is elastically closed, so that the smell of the sewer is prevented from being reversed.

During drainage, ground sewage passes through the water passing through hole of the stainless steel inner support ring 11, enters the elastic inner core 2 from the second water inlet 5, the second water outlet 6 is opened under the action of water pressure, the ground sewage flows out of the elastic inner core 2 from the second water outlet 6 and enters the outer pipe 1, and then the side wall of the outer pipe 1 is extended between the elastic inner core 2 and the outer pipe 1 to flow out of the outer pipe 1 from the first water outlet 4 and enter a sewer pipeline.

After the drainage is finished, the second water outlet 6 is elastically closed, and a water seal is formed between the lower edge of the first water outlet 4 and the second water outlet 6 by the ground sewage. When the second water outlet 6 is not tightly closed due to elastic aging, the water seal can play a role in deodorization, and the probability of odor reversion is reduced.

Example two

Referring to fig. 2, the other steps are the same as the first embodiment except that a grill 16 is attached to the first water outlet 4. The grill 16 is made of a stainless steel material and is integrally formed with the outer tube 1.
