The strainer 600 is used to filter some of the larger debris so that the debris does not flow into the drain and clog it. The stopper 700 is coupled to a lower end of the driving shaft 400, and the stopper 700 serves to restrict the filter 600 from being separated from the driving shaft 400. It will be appreciated that the filter 600 needs to be cleaned frequently, and that when it is desired to clean the filter 600, the knob 500 is lifted upwards. Specifically, because the knob 500 is fixedly connected with the transmission shaft 400, the transmission shaft 400 can be driven to ascend by lifting the knob 500 upwards, and the overflow pipe 250 and the filter 600 are driven to ascend while the transmission shaft 400 ascends. The overflow tube 250, filter 600, etc. can be quickly removed by knob 500. Therefore, the drainage device 1000 has a quick cleaning function, and the use experience of a user is improved.

Referring to fig. 6, in an embodiment of the present invention, the thickness of the sealing ring 300 is gradually reduced in a direction away from the overflow pipe 250, so that the sealing ring 300 has a slope 310. For example, the inclined surface 310 is located above the sealing ring 300, the inclined surface 310 sloping downwardly in a direction away from the overflow tube 250; alternatively, the inclined surface 310 is located below the sealing ring 300 and the inclined surface 310 slopes upwardly in a direction away from the overflow tube 250. It will be appreciated that since the overflow pipe 250 needs to be moved in the up-and-down direction, the friction between the sealing ring 300 and the inner wall of the main housing 110 is not too large to prevent the overflow pipe 250 from being moved too much. Therefore, the thickness of the sealing ring 300 is gradually reduced along the direction far away from the overflow pipe 250, the connection stability of the sealing ring 300 and the overflow pipe 250 is ensured, and meanwhile, the friction force between the sealing ring 300 and the inner wall of the main shell 110 is reduced by reducing the contact area, so that the moving fluency of the overflow pipe 250 is improved, and the components such as the transmission shaft 400, the overflow pipe 250 and the filter 600 are convenient to take out.

Wherein the filter 600 and the driving shaft 400 can be relatively moved. It can be understood that, since the overall length between the adjusting tube 140 and the main housing 110 is adjustable, the position of the transmission shaft 400 may be changed during the length adjustment process, and the transmission shaft 400 can move the filter 600 to other positions through the limiting member 700, for example, the filter 600 is moved above the annular protrusion 111, resulting in poor filtering effect. Therefore, the inner diameter of the through hole of the filter 600 is larger than the outer diameter of the transmission shaft 400, so that the filter 600 and the transmission shaft 400 can move relatively, that is, when the transmission shaft 400 moves in the up-and-down direction, the filter 600 can be kept still within a certain range of movement of the transmission shaft 400, or can be always abutted against the boss 115, so that the filter 600 is always kept below the annular protrusion 111, and the filtering effect of the filter 600 is ensured.

Referring to fig. 9, in another embodiment of the present invention, the limiting member 700 is a clamping nut, the clamping nut includes a connecting rod 720 and a limiting member 710, one end of the connecting rod 720 is fixedly connected to the limiting member 710, and the limiting member 710 is used for limiting the filter 600 to be separated from the transmission shaft 400; the end surface of the other end of the connecting rod 720 is provided with a second connecting hole (not shown in the figure), the second connecting hole extends along the axial direction of the connecting rod 720 and is provided with an internal thread, the connecting rod 720 penetrates through the through hole of the filter 600, and the lower end of the transmission shaft 400 is in threaded connection with the second connecting hole. Wherein the filter 600 and the driving shaft 400 can be relatively moved. It can be understood that, since the overall length between the adjusting sleeve 140 and the main housing 110 is adjustable, the position of the transmission shaft 400 may be changed during the length adjustment, and the transmission shaft 400 can move the filter 600 to other positions through the limiting member 700, for example, the filter 600 is moved above the annular protrusion 111, which results in poor filtering effect. Therefore, the inner diameter of the through hole of the filter 600 is larger than the outer diameter of the connection rod 720, so that the filter 600 and the transmission shaft 400 can move relatively, that is, when the transmission shaft 400 moves in the up-and-down direction, the filter 600 can be kept still within a certain range of movement of the transmission shaft 400 or can be always abutted against the boss 115, so that the filter 600 is always kept below the annular protrusion 111, and the filtering effect of the filter 600 is ensured. It should be noted that the limiting member may also be another nut, such as a double nut.
