Description

Drain structure and bathroom products

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on December 18, 2023, with application number 202323459315.6 and title “Drainage Structure and Sanitary Products,” the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present disclosure relates to the technical field of sanitary ware products, and more particularly to a water removal structure and a sanitary ware product comprising the water removal structure. Background Art

[0003] Basins, bathtubs, and other bathroom fixtures require a drain port and drain cap at the bottom to ensure drainage. There are two main configurations for normally open drains on the market: one directly screws the drain cap in to ensure the required water flow; the other adds support legs to the drain cap or to the corresponding drain port, also to ensure the required water flow.

[0004] The first solution is mainly suitable for drain caps with a rotating shape, but not for those with a non-rotating shape. Furthermore, the drain cap is prone to rotation under external forces, affecting the appearance. Furthermore, because the drain cap is an integral component connected by threads, a large space is required for proper removal, which also affects the appearance.

[0005] The second solution, placing the drain cover directly on the corresponding drain outlet of a basin, bathtub, or other bathroom fixture, can easily shift due to water flow or external forces, making it unstable and difficult to center. This creates an uneven appearance. Furthermore, inconsistent heights of the drain cover or its supporting legs can also affect the appearance. Summary of the Invention

[0006] The present disclosure aims to provide a water drain structure, the water drain cover of which can be in the shape of a rotating body or a non-rotating body, and is stable and reliable after installation and is not easily moved under the action of external force.

[0008] According to an optional embodiment of the present disclosure, the connecting member includes: an outer ring, which is detachably mounted to the base; and an inner ring, which is connected to the outer ring via a connecting arm, wherein the central axis passes through the inner ring and cannot move axially relative to the inner ring.

[0009] According to an optional embodiment of the present disclosure, one of the outer ring and the base is provided with a snap-fitting protrusion, and the other of the outer ring and the base is provided with a snap-fitting groove adapted to the snap-fitting protrusion.

[0010] According to an optional embodiment of the present disclosure, the movable assembly is configured to enable the central shaft to rotate relative to the inner ring in the movable state, and to be fixed to the inner ring by a fastener and non-rotatable relative to the inner ring in the fixed state.

[0011] According to an optional embodiment of the present disclosure, the fastener is a screw, and the screw is configured to be movable along the radial direction of the central axis, so that the central axis is tightly clamped between the screw and the inner ring in the fixed state.

[0012] According to an optional embodiment of the present disclosure, the dewatering cover includes a main body and a bottom cover arranged at the bottom of the main body, and the movable component includes a top cover arranged at the top of the central axis, wherein one of the bottom cover and the top cover is provided with a recess, and the other of the bottom cover and the top cover is provided with a mating portion accommodated in the recess, and the recess and the mating portion are matched in shape so that the bottom cover and the top cover cannot rotate relative to each other.

[0013] According to an optional embodiment of the present disclosure, the drain cover further includes a first magnet disposed between the body and the bottom cover, and the movable component further includes a second magnet disposed between the central axis and the top cover, wherein the first magnet and the second magnet attract each other.

[0029] The following detailed discussion of the implementation and use of the embodiments. However, it should be understood that the specific embodiments discussed are merely illustrative of specific ways to implement and use the present disclosure, and are not intended to limit the scope of protection of the present disclosure.

[0030] In this document, when describing the structural positions of various components, directional expressions such as "upper," "lower," "top," and "bottom" are not absolute but relative. These directional expressions are appropriate when the components are arranged as shown in the figures. However, if the positions of the components in the figures are changed, these directional expressions should be changed accordingly.

[0031] In this document, unless otherwise specified or limited, terms such as "installed" and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integrated connections; mechanical connections, electrical connections, or magnetic connections; direct connections, indirect connections, or connections through some other mechanism. Those skilled in the art will understand the specific meanings of these terms in this document based on the specific circumstances.

[0032] The preferred embodiment of the present disclosure will now be described in conjunction with the accompanying drawings, wherein the drainage structure shown is applied to a washbasin, which is a common bathroom product, sometimes also called a basin or wash basin, and includes a basin body made of ceramic or similar materials and defining a water container. It will be understood that in the present disclosure, "water" refers to various forms of fluid, including but not limited to tap water, sewage, oil stains, etc., that is, the composition of water does not affect the scope of protection of the present disclosure. In addition, the present disclosure does not limit the type of bathroom product to which the drainage structure is applied. The drainage structure can also be applied to any type of water-containing product such as a bathtub, a washing sink, etc.

[0033] As shown in Figures 1 and 2A to 2C, the washbasin includes: a basin body that defines a water container, and in order to drain water from the basin body 100, a roughly circular drain outlet 120 and a groove 110 surrounding the drain outlet 120 are provided at the bottom of the basin body 100; and a drain structure 200, which is provided at the drain outlet 120 to cover the drain outlet 120 from above and guide water from the basin body 100 through the drain outlet 120 to a drain pipe (not shown) below the basin body 100.

[0034] More specifically, the drain structure 200 includes a drain cover 210, a movable component 220, and a base 230, wherein the base 230 passes through and is fixedly mounted to the drain port 120 and defines a water flow channel 236, the drain cover 210 has a shape that matches the groove 110, so that it can be arranged in the groove 110 to cover the drain port 120, and the movable component 220 connects the drain cover 210 and the base 230. In the embodiment shown, the drain cover 210 and the groove 110 have a generally rectangular shape, but the present disclosure does not limit the shape of the drain cover 210 and the groove 110. For the sake of aesthetics, practicality, etc., the drain cover 210 and the groove 110 can be designed to have any suitable rotating or non-rotating shape.

[0035] As shown in Figures 1, 2C, 3A, 3B, and 4, the base 230 is formed by a pipe fitting 231 with external threads that defines a water flow channel 236. A skirt 2311 protruding radially outward is provided at the top of the pipe fitting 231. A first sealing ring 232, a second sealing ring 233, a washer 234, and a nut 235 are sequentially sleeved below the skirt 2311. During installation, the pipe fitting 231 with the first sealing ring 232 is first passed through the drain port 120 from top to bottom, so that the skirt 2311 abuts against the basin body 100 above the drain port 120 through the first sealing ring 232. Then, tighten the nut 235 along the pipe 231 from bottom to top, so that the nut 235 abuts against the basin body 100 below the drain outlet 120 through the washer 234 and the second sealing ring 233, so that the pipe 231 is tightly fixed to the drain outlet 120, and the first sealing ring 232 and the second sealing ring 233 prevent water from leaking between the outer wall of the pipe 231 and the basin body 100.

[0036] As shown in Figures 1, 2B, 3A, 3B, and 4, movable assembly 220 includes a connector 221 and a central shaft 222. Connector 221 is removably mounted to the inner wall of pipe 231 within water flow channel 236 and is non-rotatable relative to pipe 231. Central shaft 222 is mounted to connector 221 and has a movable state, in which it is rotatable about its axis relative to connector 221, and a fixed state, in which it is non-rotatable relative to connector 221. More specifically, connector 221 includes an outer ring 2211 removably mounted to the inner wall of pipe 231 and an inner ring 2213 connected to outer ring 2211 via a plurality of connecting arms 2214 circumferentially spaced at substantially uniform angular intervals. Based on this configuration, connector 221 functions as, for example, a sewage collector, allowing water to flow through while minimizing the entry of objects such as hair into the drainpipe, thereby preventing clogging of the drainpipe.

[0037] In the illustrated embodiment, the top of the outer ring 2211 is provided with two diametrically opposed snap-in projections 2212, and the inner wall of the tube 231 is provided with two slots 2312 corresponding to and matching the snap-in projections 2212. When the base 230 is secured to the drain outlet 120, the movable assembly 220 can be removably mounted to the base 230 through the engagement of the snap-in projections 2212 and the slots 2312, preventing the outer ring 2211 from rotating about its axis relative to the tube 231.

[0038] It is understood that the method of retaining the base 230 and the movable assembly 220 is not restrictive. According to one embodiment, a snap-fitting protrusion can be provided on the inner wall of the tube 231, and a slot corresponding to and matching the snap-fitting protrusion can be provided on the outer ring 2211. According to other embodiments, the base 230 and the movable assembly 220 can also be detachably connected to each other through external retaining, pin retaining, or similar means.

[0039] The central shaft 222 passes through the inner ring 2213 and is prevented from axially moving relative to the inner ring 2213 by bosses 2222 and stoppers 224 (e.g., retaining springs) abutting the inner ring 2213's two axial ends. In the movable state, the central shaft 222 can rotate about its axis relative to the inner ring 2213. In the fixed state, the central shaft 222 is secured to the inner ring 2213 by fasteners and cannot rotate about its axis relative to the inner ring 2213. The O-rings 223 here serve to provide a good hand feel. In this embodiment, two O-rings are mounted on the central shaft 222; however, other plastic materials may be used instead.

[0040] In the illustrated embodiment, the fastener is a screw 225. More specifically, the connector 221 further includes a fixing portion 2215 disposed on the bottom of the inner ring 2213 and defining a threaded channel extending radially from the central axis 222. This allows the screw 225 to move radially from the central axis 222 within the threaded channel and contact the central axis 222. In a fixed state, by tightening the screw 225 toward the central axis 222, the central axis 222 is tightly clamped radially between the screw 225 and the inner wall of the inner ring 2213, preventing the central axis 222 from rotating about its axis relative to the inner ring 2213. In a movable state, by loosening the screw 225 in the opposite direction from the central axis 222, the central axis 222 can rotate about its axis relative to the inner ring 2213.

[0041] In addition, the movable component 220 also includes a top cover 227 arranged on the top of the central shaft 222. The top cover 227 is covered and fixedly connected to the upper end 2221 of the central shaft 222 by, for example, threaded connection, and is detachably connected to the drain cover 210 above.

[0042] As shown in Figures 1, 2A, 3A, 3B and 6, the drain cover 210 is detachably mounted on the top of the central shaft 222 and cannot rotate about its axis relative to the central shaft 222. More specifically, the drain cover 210 includes a body 211 having a shape matching that of the groove 110 and a bottom cover 213 fixedly connected to the bottom of the body 211, for example, by a threaded connection, wherein the upper portion of the bottom cover 213 is a threaded connection portion 2131, which extends into the receiving groove 2111 of the body 211 and is threadedly connected to the receiving groove 2111, and the bottom surface of the bottom cover 213 is provided with a recessed portion 2132 having a non-rotating shape (for example, a substantially rectangular shape). Correspondingly, as shown in Figures 2B, 4, 5A and 5B, the top of the top cover 227 constitutes a fitting portion 2271 that can be accommodated in the recess 2132. The outer shape of the fitting portion 2271 is a non-rotating shape that matches the recess 2132, so that the bottom cover 213 and the top cover 227 cannot rotate relative to each other.

[0043] It is understood that the method of retaining the drain cover 210 and the movable assembly 220 is not restrictive. According to one embodiment, a non-rotating recessed portion may be provided on the top of the top cover 227, and a mating portion capable of being received within and matching the shape of the recessed portion may be provided on the bottom cover 213. According to other embodiments, the drain cover 210 and the movable assembly 220 may also be engaged with each other through a snap-fit, pin-type retaining mechanism, or similar means.

[0044] In the illustrated embodiment, the drain cover 210 and the movable component 220 are connected by magnet attraction. More specifically, the drain cover 210 further includes a first magnet 212 disposed between the body 211 and the bottom cover 213. The first magnet 212 is fixed to the interior of the threaded connection portion 2131 of the bottom cover 213, for example, by a positioning member. Correspondingly, the movable component 220 further includes a second magnet 226 disposed between the central axis 222 and the top cover 227. The first magnet 212 and the second magnet 226 attract each other, thereby allowing the drain cover 210 and the movable component 220 to be detachably connected to each other.

[0045] The dewatering structure 200 according to the present disclosure has at least a plurality of beneficial effects as described below.

[0046] The drain cover 210 (specifically the body 211) can be in the shape of a rotating body or a non-rotating body. During installation, the base 230 is first fixed to the drain port 120 of the basin body 100 at any angle, and then the movable component 220 is detachably mounted to the base 230 through the cooperation of the outer ring 2211 of the connector 221 and the pipe 231. At this time, since the central shaft 222 is not tightly fixed to the inner ring 2213 of the connector 221, in order to ensure that the drain cover 210 can be installed to the top of the central shaft 222 in the groove 110 of the basin body 100 at the correct angle, the top cover 227 of the movable component 220 can be manually rotated to drive the central shaft 222 to rotate around its axis relative to the inner ring 2213 until the top cover 227 is adjusted to the correct angle. Then, remove the movable component 220 upward from the base 230, and tighten the screw 225 to prevent the central shaft 222 from rotating relative to the inner ring 2213. Finally, the movable component 220 is reinstalled on the base 230 , and the drain cover 210 is detachably installed on the top cover 227 .

[0047] Therefore, the dewatering structure 200 disclosed in the present invention can avoid the defect that the dewatering cover 210 is difficult to be correctly installed in place due to the fact that the corresponding groove 110 on the dewatering cover 210 and the basin body 100 are non-rotating shapes, and due to the internal self-positioning of the dewatering structure 200, the dewatering cover 210 has a rotation-stop function and will not move under the action of external forces such as water flow, and ensures a uniform gap between the edge of the dewatering cover 210 and the groove 110 of the basin body 100.

[0048] Furthermore, the magnetic connection between the drain cover 210 and the movable assembly 220 is simple to operate, stable, reliable, and has a simple appearance. To remove the drain cover 210, simply press the edge of the drain cover 210 toward the wall 111 of the groove 110, causing one side of the drain cover 210 to tilt up, allowing it to be easily lifted without the need for any tools.

[0049] The technical content and technical features of the present disclosure have been disclosed above. However, it can be understood that under the creative ideas of the present disclosure, technicians in this field can make various changes and improvements to the above-disclosed concepts, but all of them fall within the scope of protection of the present disclosure.

[0050] The description of the above embodiments is intended to be illustrative rather than restrictive. The scope of protection of the present disclosure is determined by the claims.
