[0001] The utility model belongs to the technical field of pipelines and relates to a drainage joint. Background Art
[0002] The wash basin is one of the most common pieces of furniture in today's life and is widely used in kitchens, bathrooms and other places. Users fill the wash basin with water through the faucet, and after finishing washing, they can drain the water in the wash basin through the sewer pipe.
[0003] A drain joint of matching size is often required to connect the wash basin and the drain pipe. The common drain joint in the prior art generally includes a long pipe body, one end of which is connected to the drain outlet at the bottom of the wash basin by a thread or a socket, and the other end is also connected to the drain pipe port by a thread or a socket to achieve smooth drainage.
[0004] However, in actual use, whether it is the kitchen or the bathroom, when the tap water is discharged after use, the hair, food residues and other dirt mixed in the water are discharged into the sewer pipe through the drainage joint together with the water. Over time, the accumulation of these dirt increases, and eventually the sewer pipe will be blocked, affecting the user's daily use. Therefore, users are required to clean the sewer pipe regularly, but the location of the sewer pipe itself is very remote, and nowadays the decoration generally wraps the sewer pipe with decorative panels, which makes cleaning very inconvenient. Summary of the invention
[0005] The purpose of the utility model is to solve the above problems in the prior art and to propose a drainage joint. The technical problem to be solved by the utility model is: how to conveniently clean the dirt.
[0006] The purpose of the utility model can be achieved through the following technical solutions: a drainage joint, comprising a tubular body, one end of the body being a water inlet, and the other end being a water outlet, characterized in that a sewage cleaning port is provided on the side wall of the body, a plugging cover for sealing the sewage cleaning port is detachably connected to the outside of the body, a filter screen for separating the water inlet from the water outlet is detachably connected to the inside of the body, and the sewage cleaning port is arranged toward the side of the filter screen close to the water inlet.
[0007] The drainage joint is connected to the wash basin through the water inlet, and the water outlet is connected to the sewer pipe, so as to realize the smooth discharge of sewage. On this basis, the drainage joint is provided with a sewage cleaning port on the side wall of the main body, and the sewage cleaning port is blocked with a plugging cover. Under normal use, the plugging cover is installed on the main body to prevent sewage from leaking out of the sewage cleaning port. When cleaning is needed, the user can open the plugging cover and take out the dirt accumulated in the main body through the sewage cleaning port, so as to realize the purpose of quick cleaning and dredging. In addition, the drainage joint is provided with a sewage cleaning port on the main body. A filter is installed inside to separate the water inlet and outlet of the main body through the filter, and the sewage outlet is set on the side of the filter close to the water inlet of the main body. Under normal use, sewage can pass through the filter and be discharged from the main body through the outlet, while the dirt contained in the sewage can be retained inside the main body through the barrier of the filter to prevent it from entering the sewer pipe through the main body, effectively preventing the problem of inconvenience in later cleaning. In addition, the filter is specifically removed from or installed into the main body through the sewage outlet in a detachable connection manner to ensure the convenience of cleaning and replacement of the filter.
[0008] In the above-mentioned drainage joint, the body is arranged vertically, the inner wall of the body near the water outlet has an annular edge in the circumferential direction, the filter is arranged horizontally and the cross section cut vertically is U-shaped, the side wall of the filter has a flange extending radially outward along the body, the bottom of the filter passes through the annular edge and the flange abuts against the annular edge. Through this arrangement, it is ensured that the filter can be firmly kept in the body under the premise of being removable, thereby ensuring its effectiveness in filtering dirt in sewage.
[0009] In the above-mentioned drainage joint, the circumferential outer wall of the filter mesh fits with the circumferential inner wall of the annular edge, thereby further improving the installation stability of the filter mesh. In normal use, the circumferential outer wall of the filter mesh fits with the circumferential inner wall of the annular edge, thereby preventing the filter mesh from moving in the radial direction of the body under the impact of water flow.
[0010] In the above-mentioned drainage joint, the bottom circumferential edge of the filter screen is chamfered in an arc shape, which serves as a guide when installing the filter screen, ensuring the convenience of blind installation of the filter screen by the user.
[0011] In the above-mentioned drainage joint, an annular groove is provided on the inner bottom wall of the plugging cover, a sealing ring is provided in the annular groove, the plugging cover is screwed to the body and the sealing ring is pressed against the inner edge of the port of the sewage cleaning port. With this arrangement, when the plugging cover is screwed to the body and locked, the tightening force acts on the sealing ring so that the sealing ring presses against the outer wall of the port edge of the sewage cleaning port, thereby ensuring the sealing of the sewage cleaning port.
[0012] Compared with the existing technology, this drainage joint has the following advantages:
[0013] The filter screen that separates the water inlet from the water outlet is detachably connected in the body, so that under the premise of normal drainage through the body, the filter screen can filter out the dirt in the sewage, and the user can periodically open the plugging cover and clean the dirt accumulated in the body through the sewage cleaning port, ensuring that the dirt cleaning is more convenient.
