Description

Detachable anti-odor floor drain

technical field

The utility model belongs to floor drains, in particular to a detachable odor-proof floor drain.

Background technique

At present, the sewage floor drains used in residential and public places or the sewage of sanitary ware such as urinals and sinks in public places are basically sealed with water seals. This kind of water sealing method is to use the used sewage to achieve the purpose of water sealing. Bacteria and pests are easy to breed due to the residual sewage, or the water level of the water seal part is naturally lowered, resulting in bad smells in the sewer pipes, especially in the use of residential pipes, and infectious diseases are prone to occur among floor residents. In use larger insects such as cockroaches burrow in and out. At present, a kind of integral straight pipe overflow floor drain is introduced in the market. Its structure is composed of an outer cylinder and an inner cylinder. Connected, the inner cylinder is fixed in the inner cavity of the outer cylinder, the upper end of the inner cylinder is integrated with the water inlet of the outer cylinder, and the lower end is the water outlet. Sewage enters the bottom seal of the outer cylinder from the water inlets of the inner and outer cylinders, and then flows out from the overflow tank in the middle of the outer cylinder. There is residual water between the overflow tank and the bottom of the outer cylinder, which acts as a water seal. This kind of floor drain is owing to being that integral sealing performance is relatively poor, and the sealing of urceolus and downpipe junction is bad, and is inconvenient to clean simultaneously, so deodorant performance is bad.

Utility model content

The purpose of this utility model is to overcome the shortcomings of the above-mentioned technologies, and provide a detachable anti-odor floor drain, which has a long water sealing time and good anti-odor performance; it can be completely disassembled, and it is convenient to clean up sundries.

In order to achieve the above purpose, the utility model adopts the following technical solutions: a detachable anti-odor floor drain, including an outer cylinder and an inner cylinder, the upper end of the outer cylinder is a water inlet, the bottom end is provided with a bottom seal, and the middle and upper circumference of the outer cylinder is provided with an overflow The trough is connected with the sewer, and the inner cylinder is fixed in the inner cavity of the outer cylinder. It is characterized in that: the outer cylinder and the inner cylinder are connected by an inner sealing sleeve, and the upper end of the bowl-shaped stepped sealing sleeve is provided with an outer edge. There is a slit in the inner cavity, a positioning platform is provided in the center of the bottom, a positioning lip is provided at the lower opening of the positioning platform, and a hollow inner cylinder with a positioning outer edge is provided on the upper end, and its outer wall is sealed and connected with the positioning platform of the inner sealing sleeve, and the inner sealing The outer circle of the sleeve is sealed and connected with the inner cavity on the upper part of the outer cylinder.

The outer circular surface of the inner sealing sleeve is provided with at least one annular sealing rib.

The positioning lip has a height of 1.5 mm, a chamfer of 45°, and a thickness of 0.5 mm.

The inner cavity above the overflow tank of the outer cylinder is provided with four positioning feet.

The outer circle of the outer cylinder is socketed with an annular outer sealing sleeve which is sealed and connected with the sewer pipe, and an annular elastic groove is arranged in the middle of the outer sealing sleeve.

The utility model has beneficial effects: the depth of the water seal is more than 60mm, and the anti-odor performance is good. Under normal temperature conditions, the water seal time can be maintained for 30 days; it can be completely disassembled, and it is convenient to clean dirt, fluff, hair and other sundries. No bad smell will be emitted no matter when the liquid flows into the sewer pipe through the device or when no liquid flows.

Detailed ways

The specific implementation of the utility model will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

As shown in the figure, a detachable anti-odor floor drain includes an outer cylinder 1 and an inner cylinder 2 made of stainless steel. The groove 4 is also connected with the sewer, the inner cylinder is fixed in the inner cavity of the outer cylinder, the outer cylinder and the inner cylinder are connected through the inner sealing sleeve 5, and the upper end of the bowl-shaped stepped sealing sleeve is provided with an outer edge 5-1, The inner cavity is provided with a sub-port 5-2, the sub-port is used for plugging into the drain pipe of the washing machine, and the center of the bottom is provided with a positioning platform 5-3, which is used for sealing and inserting the inner cylinder, and the lower opening of the positioning platform is provided with a positioning lip 5- 4. The upper end is provided with a hollow inner cylinder for positioning the outer edge 2-1, its outer wall is in sealing connection with the positioning platform of the inner sealing sleeve, and the outer circle of the inner sealing sleeve is in sealing connection with the inner cavity of the upper part of the outer cylinder. The outer circular surface of the inner sealing sleeve is provided with at least one annular sealing rib 6, which can ensure a tighter seal between the inner sealing sleeve and the outer cylinder. The positioning lip has a height of 1.5 mm, a chamfer of 45°, and a thickness of 0.5 mm. The inner cavity above the overflow groove of the outer cylinder is provided with four positioning pins 1-1, which play a positioning role for inserting the inner sealing sleeve. After the outer wall of the hollow inner cylinder is sealed with the positioning platform of the inner sealing sleeve, there is a 1mm gap between the inner cylinder and the virtual circle formed by the four positioning feet, and the positioning lip of the inner sealing sleeve is just inserted into the gap to ensure The positioning function of the inner cylinder. The outer circle of the outer cylinder is socketed with an annular outer sealing sleeve 7 which is sealingly connected with the sewer pipe, and an annular elastic groove 8 is arranged in the middle of the outer sealing sleeve, which can ensure that the sealing sleeve is more elastic and enhance the sealing performance. The outer cylinder and the inner cylinder are connected through the inner sealing sleeve 5 to form a floor drain that can be completely disassembled. The inner sealing sleeve and the outer sealing sleeve are made of rubber material.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the structure of the present utility model in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present utility model still belong to the scope of the technical solution of the present utility model.
