Embodiment Construction

[0030] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0031] Such as figure 1 As shown, a multi-layer water seal device according to Embodiment 1 of the present invention includes a water seal box 1 connected to a sewer pipe, at least two layers of water seals 2 and at least one elastic contraction device;

[0032] The water seal box 1 is provided with at least one layer of ring groove 11, and the at least one layer of ring groove 11 surrounds the outside of the sewer pipe. The at least one layer of ring groove 11 is arranged inside and outside, and the outer ring groove 11 is higher than the A layer of ring grooves, at least each layer of water seal 2 is placed on a layer of ring grooves 11 corresponding to its position;

[0033] The elastic contraction device is use...

Abstract

The invention relates to a multilayer water seal device, which comprises a water seat box connected with a drainage pipe, at least two layers of water seals and at least one elastic contraction device. At least one layer of annular groove is positioned on the water seat box, at least one layer of annular groove is wound on the outside of the drainage pipe, at least one layer of annular groove is arranged internally and externally, the outer layer annular groove is higher than the inner layer annular groove, and at least each layer water seal is correspondingly arranged on the corresponding layer of annular layer. The elastic contraction device is used for supporting the outmost layer of water seal in at least one layer of bell-shaped water seal. The at least two layers of water seals comprise at least one layer of bell-shaped water seal, and the at least two layer of water seals are in sealed connection. A water inlet is arranged between the at least bell-shaped water seal and the water seal box, and a water outlet is arranged between the innermost layer of water seal of the at least one layer of the bell-shaped water seal and the drainage pipe. By means of the multilayer water seal device, little water can be used for washing clean, energy is saved, and the environment is protected. Due to the elastic contraction device, siphonage is effectively avoided, and the multilayer water seal device is convenient to use.

Description

technical field [0001] The invention relates to a water sealing device, in particular to a multi-layer water sealing device. Background technique [0002] Existing sewer water sealing devices generally require a large amount of water to achieve the purpose of clean flushing, and most of them have problems with poor sealing, which will cause the odor of the sewer to rise and pollute the indoor air, while the water seal with tighter sealing, All there is the problem of siphon phenomenon. Contents of the invention [0003] The purpose of the present invention is to provide a multi-layer water sealing device which saves water resources and can prevent the occurrence of siphon phenomenon in view of the deficiency of siphon phenomenon in the prior art. [0004] A multi-layer water seal device according to the present invention, comprising a water seal box connected to the downpipe, at least two layers of water seals and at least one elastic contraction device; [0005] The wat...
