TECHNICAL FIELD
[0001] The utility model belongs to the ground row wall row sewage technical field relates to a general type deodorization and backwater prevention device. BACKGROUND
[0002] In the traditional decoration, the toilet and bathroom cabinet of the bathroom are basically made into ground rows, that is, the drain pipe is directly connected to the underground pipe for drainage. However, in recent years, with the popularity of hanging toilets and suspended bathroom cabinets, the drainage method is no longer single, and many owners choose wall row, that is, the outlet of the water pipe is connected with the sewage pipe on the wall, and the sewage pipe is hidden in the wall, further removing the sewage. Wall row hides the drain pipe in the wall, so that the bottom of the toilet or bathroom cabinet is free of exposed and troublesome drain pipes, and the whole is more atmospheric and beautiful. Because there is no lower drain port and drain pipe, there is no sanitary dead angle at the bottom of the toilet or bathroom cabinet, which is convenient for cleaning and sanitation, and the space below the bathroom cabinet can be fully utilized.
[0003] At present, there are various angle specifications of wall row sewage pipes, among which the common wall row sewage pipes are 90-degree drain pipes (referring to the drain pipe being arranged at an angle of 90° with the wall surface) and 45-degree drain pipes (referring to the drain pipe being arranged at an angle of 45° with the wall surface). In order to enhance the deodorization and backwater prevention effect, people usually install a deodorization and backwater prevention device on the drain pipe. The existing deodorization and backwater prevention device comprises a pipe body and a deodorization core arranged on the pipe body and used for cutting off or connecting the two ends of the pipe body. In use, the pipe body of the deodorization and backwater prevention device is inserted into the drain pipe. However, there is still a lack of a deodorization and backwater prevention device that can be used for 45-degree drain pipes and 90-degree drain pipes on the market. Related enterprises have to produce two specifications of deodorization and backwater prevention devices that match 45-degree drain pipes and 90-degree drain pipes respectively, which brings a lot of inconvenience to the production, logistics, transportation and storage of enterprises.
