TECHNICAL FIELD
[0001] The present application relates to the technical field of water drainers, in particular to a universal water drainer. BACKGROUND
[0002] Sanitary wares such as washbasins usually need to be provided with water drainers to connect the sanitary wares with sewer pipes to realize the discharge of waste water. Taking a washbasin as an example, a water drainer compatible with the washbasin usually comprises an upper threaded pipe and a lower threaded pipe. The top end of the lower threaded pipe abuts against the bottom of a water outlet of the washbasin. The upper threaded pipe is penetrated by the water outlet of the washbasin in the upward direction and is arranged in the lower threaded pipe. The upper threaded pipe and the lower threaded pipe are screwed together to realize the connection with the washbasin. The lower threaded pipe is connected with the sewer pipe through a pipe fitting. The water drainer of this structure has certain defects in actual application. For example, the washbasins are now mostly divided into overflow type and non-overflow type structures. The washbasin with overflow has a hollow interlayer to connect the overflow hole of the washbasin with the water outlet at the bottom of the washbasin. When the washbasin with overflow is used, a through opening needs to be formed in the wall of the upper threaded pipe. On the one hand, the water in the washbasin can flow downward through the opening at the top of the upper threaded pipe. On the other hand, the water in the overflow hole of the washbasin can flow into the upper threaded pipe through the interlayer and the through opening in the side wall of the upper threaded pipe. The formation of the through opening affects the structural strength of the upper threaded pipe. Moreover, the water drainer needs to be adapted to the washbasins with overflow and non-overflow respectively, and the applicability of the water drainer needs to be improved. CONTENT OF THE UTILITY MODEL
[0003] The purpose of the present application is to provide a universal water drainer which has high overall structural strength and can be simultaneously used for the installation of washbasins with overflow and non-overflow, thereby effectively solving the deficiencies in the prior art.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0024] like Figures 1-5As shown, the embodiment of the present application provides a universal sewer, which is applied to the sewerage of sanitary wares and connects the sanitary wares with the sewer pipe. The traditional basin sewer usually includes an upper threaded pipe and a lower threaded pipe. When the upper threaded pipe is connected with the basin, the top end of the lower threaded pipe abuts against the bottom of the water outlet of the basin, the upper threaded pipe penetrates the water outlet of the basin from the top of the basin to the bottom and is screwed into the lower threaded pipe, the upper threaded pipe and the lower threaded pipe are screwed to clamp the basin and complete the installation, and then the bottom end of the lower threaded pipe is connected with the sewer pipe through other pipe fittings. When the basin is an overflow basin, the basin has a cladding layer on the thickness, the cladding layer connects the overflow hole and the water outlet of the basin, and then a through hole is formed in the wall of the upper threaded pipe, so that the overflow in the cladding layer can enter the upper threaded pipe through the through hole and be discharged through the lower threaded pipe. The through hole formed in the upper threaded pipe necessarily affects the overall structural strength of the pipe fitting, and different upper threaded pipes need to be provided for the overflow basin and the non-overflow basin, which has poor adaptability. For example, when the upper threaded pipe with the through hole in the side wall is installed in the non-overflow basin, part of the water in the basin will flow into the through hole of the upper threaded pipe when the water flows from the upper threaded pipe to the lower threaded pipe, which causes the sewage to be left and is unhygienic. The universal sewer of the present application aims to improve the applicability, so that it can be installed in the overflow basin and the non-overflow basin, and the hole is not formed in the pipe fitting to improve the structural strength of the component.
[0025] The universal sewer includes a first pipe fitting, a second pipe fitting 200 and a third pipe fitting 300. The first pipe fitting, the second pipe fitting 200 and the third pipe fitting 300 are all in the form of a pipe. Preferably, the first pipe fitting, the second pipe fitting 200 and the third pipe fitting 300 are all in the form of a circular pipe. The first pipe fitting has a first water inlet and a first water outlet. Taking the vertical first pipe fitting as an example, the top port of the first pipe fitting is the first water inlet, and the first water outlet is arranged near the bottom end of the first pipe fitting. The second pipe fitting 200 is arranged in the first pipe fitting and near the first water inlet of the first pipe fitting. The second pipe fitting 200 and the first pipe fitting are connected with each other, and a first flow channel is formed between the inner wall of the first pipe fitting and the outer wall of the second pipe fitting 200. The third pipe fitting 300 is arranged in the second pipe fitting 200 and can move in the second pipe fitting 200. The third pipe fitting 300 has a third water inlet and a third water outlet. Preferably, the first pipe fitting, the second pipe fitting 200 and the third pipe fitting 300 are coaxially arranged. The top port of the third pipe fitting 300 constitutes the third water inlet, and the bottom port of the third pipe fitting 300 constitutes the third water outlet. The part of the third pipe fitting 300 from the third water inlet to the third water outlet constitutes a third flow channel, that is, the inside of the third pipe fitting 300 constitutes the third flow channel.

In this way, the applicability to the overflowed wash basin is realized. If there is no overflow, only the water in the wash basin is discharged through the third flow channel, and the water directly flows downward and is discharged through the third pipe fitting 300. The water will not remain in the first flow channel, will not cause sewage to be stored in other positions, and will avoid the opening of the opening on the third pipe fitting 300, so that the overall structural strength of the pipe fitting is higher. Therefore, the applicability of the drain is improved, the drain can be used for both overflowed wash basins and non-overflowed wash basins, and the structural strength of the accessory is improved.
