Easy to disassemble and easy to assemble double water seal floor drain

Abstract

The invention discloses easy to disassemble and easy to assemble double water seal floor drain. The drain comprises a floor drain pre-embedded shell, a second seal positioning sleeve, a spiral cover plate and a sintered net, and the inner side of the floor drain pre-embedded shell is sleeved with a first a sealing positioning sleeve; the upper end of a second sealing positioning sleeve is connected to the inner side of the first sealing positioning sleeve, the top of the second sealing positioning sleeve is covered with a water screen net plate, the spiral cover plate is located above the second sealing positioning sleeve, a first blocking bowl is disposed between the second sealing positioning sleeve and the first sealing positioning sleeve, the sintering net is fixedly mounted on the inner wall of a fixing ring, and a second blocking bowl is connected to the floor drain pre-embedded shell through the fixing ring. The drain is convenient to disassemble and assemble, and is composed ofa plurality of separate assemblies, which facilitates the production and processing of the floor drain, two S-connected double water seal bypass waterway designs are formed after assembly, water sealbackflow resistance is increased, and the risk of backflow is reduced.

Description

technical field [0001] The invention relates to the technical field of floor drains, in particular to an easily dismantled and easy-to-install double-water-sealed floor drain. Background technique [0002] The floor drain refers to the drainage device connected between the ground and the drainage system. It is an important interface connecting the drainage system and the indoor ground. As an important part of the drainage system in the house, its performance directly affects the quality of the indoor air, and it is important for the bathroom. Odor control is very important. The existing floor drains on the market are mainly divided into water-sealed floor drains and non-water-sealed floor drains. accepted by the residents. [0003] Especially for food processing workshops, pharmaceutical workshops, and even injection production workshops that have special and strict requirements on cleanliness, floor drains need to be installed. All may cause the problem of large-scale con...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an easy-to-disassemble and easy-to-install double water-sealed floor drain to solve the above-mentioned background technology. It is proposed that the existing floor drain adopts a primary water-sealed device, which will easily cause the water seal to evaporate and fail, causing the indoor space to be directly the same as the sewage pipe and be blocked. Pollution, difficult to fix, inconvenient to disassemble and install, and unsafe to clean
