Description

Technical Field

[0001] The utility model belongs to the technical field of drainage floor drain design, in particular to a drainage PVC deodorizing floor drain base. Background Art

[0002] Drainage floor drain is a kind of drainage equipment commonly found in kitchens, bathrooms, laundry rooms and other places. Its main function is to collect and discharge sewage, rainwater and other wastewater to ensure the smooth progress of indoor washing and cleaning activities, while effectively preventing safety hazards such as slipping on the ground caused by leakage and water accumulation. Drainage floor drains are usually composed of drainage pipes, filters, drain hole covers and other parts. Among them, the drainage pipe is responsible for draining wastewater from the use area to the floor drain, the filter net can intercept large particles of debris to prevent clogging of the drainage pipe, and the drain hole cover is the outlet on the ground, through which sewage is discharged to the sewer. Drainage floor drains play an indispensable role in our lives. Through its setting, we can conveniently and efficiently remove wastewater, maintain hygiene and cleanliness, and improve living comfort. Therefore, in the process of house construction and decoration, it is very important to choose high-quality and applicable drainage floor drains to ensure the convenience and safety of daily life.

[0003] The existing floor drain is connected to the sewage pipe. When the sewage in the pipe flows back, it is easy to pollute the floor drain and bring odor through the floor drain to affect the smell in the house. The floor drain has poor odor-proof ability. Utility Model Content

[0004] The utility model aims to provide a PVC deodorizing floor drain base for drainage to solve the problems existing in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A PVC deodorizing floor drain base for drainage, comprising a top cover device, a connecting device is arranged at the bottom of the top cover device, and a water outlet device is arranged at the bottom of the connecting device; the connecting device comprises a liquid inlet pipe, a positioning ring is fixedly arranged at the top of the liquid inlet pipe, and a bottom pipe is fixedly arranged at the bottom of the liquid inlet pipe; the water outlet device comprises a receiving box, and an overflow baffle is fixedly arranged on the top of the receiving box, a water seal pipe is fixedly arranged on the outside of the overflow baffle, a water outlet pipe is fixedly arranged on one side of the water seal pipe, a connector is fixedly arranged on the outer end of the water outlet pipe, and an external pipe is arranged on one side of the connector.

[0007] Furthermore: the top cover device includes a filter element, a top seat is arranged above the filter element, a mounting sleeve is fixedly arranged at the bottom of the top seat, and a grid plate is arranged at the top of the top seat.

[0008] Furthermore: the top seat is square, and the mounting sleeve is circular.

[0009] Furthermore: the mounting sleeve and the top seat are integrally formed, and the filter element is located on the top of the liquid inlet pipe.

[0010] Furthermore: the bottom of the liquid inlet pipe is funnel-shaped.

[0011] Furthermore: the water seal pipe and the liquid inlet pipe are integrally formed, and the water seal pipe is in the shape of a circular ring tube.

[0012] Furthermore: the water outlet pipe and the water seal pipe are integrally formed.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The water in the house flows along the bottom plate through the grid plate into the top seat, and then enters the liquid inlet pipe. The filter element filters the larger impurities in the sewage to prevent the bottom pipe from being blocked. The filtered water passes through the bottom pipe and falls into the receiving box to form a buffer to prevent the flow rate from being too fast. Then the sewage gradually rises in the receiving box. Finally, the water level exceeds the overflow baffle. The excess water flows into the water seal pipe and then is discharged along the outlet pipe and the external pipe. Part of the water remains in the water seal pipe and the receiving box. By setting the water seal pipe and the receiving box, a small amount of sewage is retained in the floor drain. This part of water can block the liquid inlet pipe, so that the odor generated by the other sewage pipes in the house will not return to the room along the pipe, thereby improving the odor-proof ability of the floor drain;

[0015] 2. When the sewage inside the pipeline flows back into the device along the external pipe, the circular water seal pipe can reduce the water flow rate and reduce the impact force of the backflowing sewage. At the same time, the overflow baffle can prevent the sewage from further backflow, prevent the connection device from being contaminated, and further improve the cleanliness of the device.

When in use, the water in the house flows along the bottom plate through the grid plate 104 into the top seat 102, and then enters the liquid inlet pipe 201. The filter element 101 filters the larger volume of impurities in the sewage to prevent clogging the bottom pipe. The filtered water passes through the bottom pipe 203 and falls into the receiving box 301 to form a buffer to prevent the flow rate from being too fast, and then the sewage in the receiving box 301 gradually rises, and finally the water level exceeds the overflow baffle 302. The excess water flows into the water seal pipe 303, and then is discharged along the outlet pipe 304 and the external pipe 306. A part of the water remains in the water seal pipe 303 and the receiving box 301. By arranging the water seal pipe 303 and the receiving box 301, a small amount of sewage is retained in the floor drain. This part of water can block the liquid inlet pipe 201, so that the odor generated by the other sewage pipes in the house will not return to the room along the pipe, thereby improving the odor-proof ability of the floor drain. When the sewage in the pipe flows back into the device along the external pipe 306, the annular water seal pipe 303 can reduce the water flow rate and reduce the impact force of the reversed sewage. At the same time, the overflow baffle 302 can prevent the sewage from further flowing back, prevent the connecting device 2 from being contaminated, and further improve the cleanliness of the device.
