In addition, the utility model is not limited to the type of bathroom products to which the dewatering structure is applied, and the dewatering structure can be applied to any type of water-bearing products such as bathtubs, washing pools and the like.

As shown in fig. 1 and 2A to 2C, the basin includes a basin body defining a water container, a substantially circular water removal opening 120 and a recess 110 surrounding the water removal opening 120 provided at the bottom of the basin body 100 in order to drain water from the basin body 100, and a water removal structure 200 provided at the water removal opening 120 to block the water removal opening 120 from above and guide water from the basin body 100 to a drain pipe (not shown) below the basin body 100 via the water removal opening 120.

More specifically, the dewatering structure 200 includes a dewatering cap 210, a movable assembly 220, and a base 230, wherein the base 230 is fixedly mounted to the dewatering opening 120 and defines a water flow channel 236, and the dewatering cap 210 has a shape that fits into the recess 110 so as to be capable of being disposed in the recess 110 to block the dewatering opening 120, and the movable assembly 220 connects the dewatering cap 210 with the base 230. In the illustrated embodiment, the water removal cover 210 and the recess 110 have a substantially rectangular outer shape, but the outer shape of the water removal cover 210 and the recess 110 is not limited by the present utility model. The dewatering cap 210 and recess 110 can be designed to have any suitable solid or non-solid shape for aesthetic, practical, etc. purposes.

As shown in fig. 1, 2C, 3A, 3B and 4, the base 230 is formed of a pipe 231 defining a water flow passage 236 and having external threads, a skirt 2311 protruding radially outward is provided at the top of the pipe 231, and the pipe 231 is sequentially sleeved with a first seal 232, a second seal 233, a washer 234 and a nut 235 under the skirt 2311. In installation, the pipe 231 with the first seal 232 is first passed through the water outlet 120 from top to bottom so that the skirt 2311 abuts the bowl 100 above the water outlet 120 via the first seal 232. Then, the nut 235 is screwed down along the pipe 231 from the bottom up so that the nut 235 abuts to the tub 100 below the water removal opening 120 through the gasket 234 and the second sealing ring 233, thereby the pipe 231 is tightly fixed to the water removal opening 120, and leakage of water from between the outer wall of the pipe 231 and the tub 100 is prevented by the first sealing ring 232 and the second sealing ring 233.

As shown in fig. 1, 2B, 3A, 3B and 4, the movable assembly 220 includes a connection member 221 and a central shaft 222, wherein the connection member 221 is detachably mounted to an inner wall of the pipe 231 within the water flow passage 236 and is non-rotatable with respect to the pipe 231, and the central shaft 222 is mounted to the connection member 221 and has a movable state rotatable with respect to the connection member 221 about an axis thereof and a fixed state non-rotatable with respect to the connection member 221. More specifically, the connection member 221 includes an outer ring 2211 detachably mounted to an inner wall of the pipe 231 and an inner ring 2213 connected to the outer ring 2211 through a plurality of connection arms 2214 circumferentially distributed at substantially uniform angular intervals. Based on this configuration, the connection member 221 has, for example, a function of a dirt catcher, that is, the connection member 221 allows water to pass therethrough but can prevent objects such as hair from entering the drain pipe as much as possible, thereby preventing the drain pipe from being clogged.

In the illustrated embodiment, the top of the outer ring 2211 is provided with two radially opposite clamping projections 2212, and the inner wall of the tube 231 is provided with two clamping grooves 2312 corresponding to the two clamping projections 2212 respectively and having a shape matching with each other. After the base 230 is secured to the water removal port 120, the movable assembly 220 can be detachably mounted to the base 230 by the engagement of the snap-fit protrusions 2212 with the snap-fit grooves 2312, and the outer ring 2211 is made non-rotatable about its axis relative to the pipe 231.

It will be appreciated that the manner of spacing between the base 230 and the movable assembly 220 is not limiting. According to one implementation variant, a snap-fit protrusion may be provided on the inner wall of the tube 231, and a snap-fit groove corresponding to the snap-fit protrusion and having a shape that is compatible with the snap-fit protrusion may be provided on the outer ring 2211. According to other embodiments, the base 230 and the movable assembly 220 may be detachably connected to each other by a form-fitting, pin-fitting, or the like.

The central shaft 222 passes through the inner ring 2213 and is not axially movable relative to the inner ring 2213 by bosses 2222 and stoppers 224 (e.g., snap springs) respectively abutting to both axial ends of the inner ring 2213. In the movable state, the central shaft 222 is rotatable about its axis relative to the inner ring 2213. In the secured state, the central shaft 222 is secured to the inner ring 2213 by fasteners and is not rotatable about its axis relative to the inner ring 2213. Here, the O-ring 223 serves to provide a good feel, and the present embodiment is sleeved on the central shaft 222 and has two O-rings, and other plastic materials may be used instead.

In the illustrated embodiment, the fastener is a screw 225. More specifically, the connection 221 further includes a fixing portion 2215 provided at the bottom of the inner ring 2213 and defining a threaded passage extending in a radial direction of the central shaft 222 such that the screw 225 is movable in the threaded passage in the radial direction of the central shaft 222 and contacts the central shaft 222. In the fixed state, the screw 225 is forcibly tightened toward the central shaft 222 such that the central shaft 222 is tightly sandwiched between the screw 225 and the inner wall of the inner ring 2213 in the radial direction thereof, thereby making the central shaft 222 non-rotatable about the axis thereof with respect to the inner ring 2213. In the active state, the central shaft 222 is made rotatable about its axis relative to the inner ring 2213 by unscrewing the screw 225 opposite to the central shaft 222.

The movable module 220 further includes a top cover 227 provided on top of the center shaft 222, and the top cover 227 is fixedly coupled to the upper end 2221 of the center shaft 222 by, for example, screwing, and is detachably coupled to the upper dewatering cover 210.

As shown in fig. 1, 2A, 3B and 6, the water removal cover 210 is detachably mounted to the top of the center shaft 222 and is not rotatable about its axis relative to the center shaft 222. More specifically, the water removal cover 210 includes a body 211 shape-interfitted with the recess 110 and a bottom cover 213 fixedly coupled to the bottom of the body 211, for example, by screwing or the like, wherein an upper portion of the bottom cover 213 is a screw coupling portion 2131, the screw coupling portion 2131 is projected into the accommodation groove 2111 of the body 211 and screw-coupled with the accommodation groove 2111, and a bottom surface of the bottom cover 213 is provided with a recess 2132 of a non-revolution body shape (for example, a substantially rectangular shape). Correspondingly, as shown in fig. 2B, 4, 5A and 5B, the top of the top cover 227 constitutes an engaging portion 2271 that can be accommodated in the recess 2132, and the engaging portion 2271 has a non-revolving body shape that is in cooperation with the recess 2132 so that the bottom cover 213 and the top cover 227 are not rotatable relative to each other.

It will be appreciated that the manner of spacing between the dewatering cap 210 and the movable assembly 220 is not limiting. According to one implementation variant, a recess of non-revolving body shape may be provided at the top of the top cover 227, and a mating portion capable of being accommodated in the recess and of mating with the recess shape is provided on the bottom cover 213. According to other embodiments, the water removal cap 210 and the movable assembly 220 may also be engaged with each other by a snap fit, a pin fit, or the like.

In the illustrated embodiment, the water removal cap 210 is attached to the movable assembly 220 by magnetic attraction. More specifically, the water removal cover 210 further includes a first magnet 212 disposed between the body 211 and the bottom cover 213, and the first magnet 212 is fixed to the inside of the screw connection portion 2131 of the bottom cover 213, for example, by a positioning member. Correspondingly, the movable assembly 220 further comprises a second magnet 226 disposed between the central shaft 222 and the top cover 227, and the first magnet 212 and the second magnet 226 attract each other, so that the water removal cover 210 and the movable assembly 220 are detachably connected to each other.

The dewatering structure 200 according to the present utility model has at least a number of benefits as described below.

The dewatering cap 210 (specifically, the main body 211) may be in a solid shape or a non-solid shape. In the installation, the base 230 is fixedly installed to the water drain port 120 of the tub 100 at an arbitrary angle, and then the movable assembly 220 is detachably installed to the base 230 by the engagement of the outer ring 2211 of the connection member 221 with the pipe 231. At this time, since the central shaft 222 is not tightly fixed to the inner ring 2213 of the connection member 221, in order to ensure that the water removal cover 210 can be mounted to the top of the central shaft 222 in the groove 110 of the tub 100 at a correct angular position, the central shaft 222 can be rotated about its axis relative to the inner ring 2213 by manually rotating the top cover 227 of the movable assembly 220 until the top cover 227 is adjusted to the correct angular position. The movable assembly 220 is then removed upwardly from the base 230, and the central shaft 222 is prevented from rotating relative to the inner ring 2213 by tightening the screws 225. Finally, the removable assembly 220 is reinstalled to the base 230 and the water removal cap 210 is removably attached to the top cover 227.

Therefore, the dewatering structure 200 of the present utility model can avoid the defect that the dewatering cover 210 is difficult to be correctly installed in place due to the non-revolving body shape of the dewatering cover 210 and the corresponding groove 110 on the tub 100, and the dewatering cover 210 has a rotation stopping function, does not move under the action of external force such as water flow due to the self-positioning of the inside of the dewatering structure 200, and ensures a uniform gap between the edge of the dewatering cover 210 and the groove 110 of the tub 100.

In addition, the connection mode between the water removing cover 210 and the movable component 220 through the magnet adsorption is simple to operate, stable and reliable, and the appearance is concise. When the water removal cover 210 needs to be removed, only the edge portion of the water removal cover 210 needs to be pressed towards the wall surface 111 of the groove 110, so that one side of the water removal cover 210 can be lifted easily without any tool.

While the foregoing has described the technical content and features of the present utility model, it will be appreciated that those skilled in the art, upon attaining the teachings of the present utility model, may make variations and improvements to the concepts disclosed herein, which fall within the scope of the present utility model.
