Problems solved by technology
After this type of drain valve has been used for a period of time, solid objects (especially human hair) are deposited in the valve body, resulting in blockage of the water flow channel in the valve body and poor drainage.
Even too much human hair hangs in the spool and / or telescopic mechanism, resulting in problems such as the inability of the spool to telescopically move, or the failure of the telescopic mechanism, which reduces the service life
[0003] In addition, the opening and closing mechanism of the existing drain valve for controlling drainage is relatively complicated, and when it is in the closed state, the sealing effect is not good

Embodiment Construction
[0010] Such as Figure 1 to Figure 21 A drain valve shown includes a valve body 10, a valve core 20 and a telescoping mechanism 30;
[0011] The valve body 10 is provided with a water inlet 101, a water outlet 102 and a water flow channel 103 extending from the water inlet 101 to the water outlet 102;
[0012] The telescopic mechanism 30 is installed in the valve body 10, and in this embodiment, the telescopic mechanism 30 is located on the water flow channel 103;
[0013] The valve core includes a mandrel and a gland 201 that can be pressed by the user. One end of the mandrel is connected to the gland 201, and the other end of the mandrel is inserted into the valve body 10 from the water inlet 101 and connected to the telescopic mechanism 30. In particular, the lower end of the large-diameter section of the lower mandrel of the mandrel is inserted into the valve body 10 from the water inlet 101 and connected with the telescopic mechanism 30;
[0014] When the gland 201 is p...

The invention relates to an opening and closing mechanism which comprises a sealing plug and a sealing ring. The sealing plug comprises a plugging-in body. The plugging-in body is a circular truncated cone body with the diameter gradually increased in the direction from the bottom face of the plugging-in body to the top face of the plugging-in body. The top face of the plugging-in body is provided with an annular sealing plug flange which extends in the radial direction of the plugging-in body. The sealing ring comprises a sealing ring body and a sealing ring flange which extends in the radial direction of the sealing ring body. A sealing ring penetrating hole allowing the plugging-in body to be inserted therein is defined by the sealing ring body. The diameter of the sealing ring penetrating hole is gradually reduced in the direction that the plugging-in body is inserted into the sealing ring penetrating hole. When the plugging-in body is inserted in the sealing ring penetrating hole, the sealing ring penetrating hole is blocked through the plugging-in body; and when the plugging-in body is pulled out of the sealing ring penetrating hole, the sealing ring penetrating hole is opened. The opening and closing mechanism is simple in structure and relatively high in sealing performance, and the water leaking phenomenon happening when an applied draining valve is in a closed state is avoided.
Description
technical field [0001] The invention relates to a drain valve mainly used in bathroom equipment such as washbasins and bathtubs, in particular to an opening and closing mechanism of the drain valve. Background technique [0002] In the prior art, the drain valves used in sanitary equipment such as washbasins and bathtubs are generally press telescopic valves, which include a valve body, a valve core and a telescopic mechanism. After this type of drainage valve is used for a period of time, solid matter (especially human hair) is deposited in the valve body, which causes the water flow channel in the valve body to be blocked and the drainage is not smooth. Even too much human hair hangs in the spool and / or the telescopic mechanism, resulting in problems such as the inability of the spool to telescopically move, or the failure of the telescopic mechanism, which reduces the service life. [0003] In addition, the opening and closing mechanism for controlling the drainage of th...
