Description

Technical Field

[0001] This invention relates to the field of bathroom fixtures, and in particular to a sealing component and a liftable basin. Background Technology

[0002] Washbasins, as an essential bathroom fixture, are widely used in people's lives. Traditional washbasins are fixed and mainly used for washing hands and face. Their countertop area is relatively small, making it inconvenient when storing multiple items. To address this, a lift-up washbasin has been developed. This basin has a basin seat with a sliding lifting mechanism within it. When lowered, the lifting mechanism forms a water reservoir by closing with the basin's walls. When raised, it is roughly flush with the countertop, thus compensating for the limited countertop space and allowing for more items to be placed, meeting users' daily needs. However, since the lifting mechanism is a moving part, it must effectively seal against the basin's walls when lowered. This places high demands on the sealing gasket: it must not affect the smoothness of the lifting mechanism's movement while also providing an effective seal when water is stored. Currently, the sealing gasket is generally made of silicone or rubber, forming multiple seals with the basin's walls. However, the deformation capacity of this sealing gasket is still limited. During the lifting process of the lifting component, it is easily worn due to the squeezing and friction of the pelvic cavity wall, which ultimately leads to a significant reduction in water sealing performance. Summary of the Invention

[0003] This invention addresses the technical problems existing in the prior art by providing a sealing component and a lifting basin, which improves the deformation capacity of the sealing component to reduce wear and enhance water sealing performance.

[0004] The technical solution adopted by the present invention to solve its technical problem is as follows: a sealing component, including a sealing gasket and a sealing support, the sealing support including an inner support body whose shape is adapted to the sealing gasket and a plurality of elastic sheets located around the inner support body, the plurality of elastic sheets being distributed circumferentially at intervals along the inner support body, and there being a deformation space between the elastic sheets and the inner support body for the elastic sheets to elastically swing inward; the sealing gasket includes an inner sealing body, an outer sealing body and a transition body disposed between the inner sealing body and the outer sealing body, the outer sealing body being fitted over the plurality of elastic sheets.

[0005] Furthermore, each of the elastic sheets has a backstop portion on its outer side, and the outer sealing body has a ring of anti-backstop locking platform on its inner side, forming an anti-backstop locking connection between the backstop portion and the anti-backstop locking platform.

[0006] Furthermore, the outer sealing body includes an upper sealing lip and a lower sealing lip distributed vertically, and a negative pressure cavity is formed between the upper sealing lip and the lower sealing lip in the sealed state.

[0007] Furthermore, the outer diameter of the upper sealing lip gradually decreases from top to bottom, and the longitudinal section of the upper sealing lip is an upwardly extending inclined strip; the lower sealing lip is fitted outside the plurality of elastic sheets; the transition body is located between the bottom of the upper sealing lip and the top of the inner sealing body, and fits above the deformation space.

[0008] Furthermore, the inner sealing body is fitted onto the inner support body.

[0009] Furthermore, the inner sealing body has inner and outer walls, and an annular cavity with an opening at the lower end is formed between the two walls. The inner support body is at least partially housed within the annular cavity. A limiting step surface is provided at the upper end of the inner sealing body.

[0010] Furthermore, the plurality of elastic sheets are partially divided by an outer support body located around the inner support body and forming a ring, and the upper ends of the plurality of elastic sheets are free ends; a bottom support body is provided between the bottom end of the outer support body and the bottom end of the inner support body.

[0011] The present invention also provides a liftable basin, including a basin base, a lifting component, and a drive mechanism. The basin base has a basin cavity that extends vertically. The lifting component is slidably disposed within the basin cavity along the height direction and is adapted to form a water storage tank by surrounding the perimeter walls of the basin cavity. The drive mechanism is disposed on the basin base and is adapted to drive the lifting component to rise or fall. The lifting component includes a base. The lifting component also includes a sealing component as described above in the present invention. The sealing component is fitted outside the base, and the inner sealing body abuts against the outer side of the base, while the outer sealing body abuts against the cavity wall of the basin cavity.

[0012] Furthermore, a guide mechanism is provided between the base and the basin seat. The guide mechanism includes at least one set of guide components, which includes a guide post and a guide sleeve. One of the guide post and the guide sleeve is fixed to the base, and the other of the guide post and the guide sleeve is fixed to the basin seat. The guide sleeve and the guide post are adapted to slide together along the lifting direction of the lifting component.

[0013] Furthermore, the bottom of the pelvic cavity is provided with an inner flange, the top of the guide sleeve is fixedly inserted through the inner flange, the bottom of the guide sleeve is fixedly connected to a fixing plate provided on the drive mechanism; the top of the guide post is fixedly connected to the base.

[0014] Furthermore, the drive mechanism includes a lifting motor, the body of which is located below the pelvic cavity. The output shaft of the lifting motor faces upward and is fixedly connected to the middle of a polygonal bracket. Each end corner of the polygonal bracket is fixedly connected to the base.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Since the sealing component of the present invention includes the sealing gasket and the sealing bracket, the sealing bracket includes the inner support body and a plurality of elastic sheets located around the inner support body. There is a deformation space between the elastic sheets and the inner support body that allows the elastic sheets to elastically swing inward. The sealing gasket includes the inner sealing body, the outer sealing body and the transition body. The outer sealing body is fitted over the plurality of elastic sheets. This allows the present invention to utilize the plurality of elastic sheets to improve the elastic deformation capability of the sealing gasket. As a result, when the sealing component of the present invention is applied to dynamic sealing, it can reduce wear and improve water sealing performance.

[0017] 2. Each elastic sheet has a backstop on its outer side and an anti-backstop plate on its inner side. The backstop and the anti-backstop plate form an anti-backstop engagement, thereby ensuring that the sealing gasket and the sealing bracket are effectively engaged for a long time and preventing them from separating.

[0018] 3. The outer sealing body includes an upper sealing lip and a lower sealing lip distributed vertically. A negative pressure cavity is formed between the upper sealing lip and the lower sealing lip in the sealed state, so that the sealing component of the present invention can achieve two seals at the same time, and can also improve the sealing effect of the present invention by utilizing the negative pressure cavity.

[0019] 4. The outer diameter of the upper sealing lip gradually decreases from top to bottom, and the longitudinal section of the upper sealing lip is an upwardly extending inclined strip, so that the upper sealing lip can scrape off the dirt adhering to the cavity wall of the pelvis when it rises or falls.

[0020] 5. The inner sealing body is fitted onto the inner support body, and the inner support body can limit the inner sealing body, so that the inner sealing body fits more tightly when sealing.

[0021] 6. The guide mechanism ensures smoother movement of the lifting components.

[0022] 7. The multi-angle bracket design allows the base to bear force at multiple points, making the base more stable when it is raised or lowered.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments; however, the sealing component and lifting basin of the present invention are not limited to the embodiments. Attached Figure Description

[0035] In this invention, the use of terms such as "upper" and "lower" to indicate orientation or positional relationships is based on the orientation or positional relationships shown in the accompanying drawings and is only for the convenience of describing the invention. It does not indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "a plurality of" refers to two or more.

[0036] Please see Figures 1-3As shown, a sealing component of the present invention includes a sealing gasket 1, which is annular, but not limited to this; in other embodiments, the sealing gasket may be square, etc. The present invention also includes a sealing support 2, which includes an inner support 21 and a plurality of elastic sheets 221 located around the inner support 21. The shape of the inner support 21 is adapted to the shape of the sealing gasket 1, that is, the inner support 21 is also annular. The plurality of elastic sheets 221 are distributed at intervals along the circumference of the inner support 21, and there is a deformation space between the elastic sheets 221 and the inner support 21 for the elastic sheets 221 to elastically swing inward. Specifically, the plurality of elastic sheets 221 are partially divided by an outer support 22 located around the inner support 21 and forming an annular shape; the upper ends of the plurality of elastic sheets 221 are all free ends; a bottom support 23 is provided between the bottom end of the outer support 22 and the bottom end of the inner support 21. The sealing gasket 1 includes an annular inner sealing body 11, an annular outer sealing body 12, and a ring of transition body 13 disposed between the inner sealing body 11 and the outer sealing body 12. The inner sealing body 11 is fitted onto the inner support body 21, and the outer sealing body 12 is fitted onto the outside of the plurality of elastic sheets 221.

[0037] In this embodiment, each elastic sheet 221 has a retaining portion 222 on its outer surface, and the outer sealing body 12 has a ring of anti-retraction locking platform 123 on its inner surface. The retaining portion 222 and the anti-retraction locking platform 123 form an anti-retraction locking connection. The retaining portion 222 is specifically located at the top of the elastic sheet 221, and the anti-retraction locking platform 123 is located at the bottom of the outer sealing body 12. In this way, the sealing gasket 1 and the sealing bracket 2 can be effectively engaged for a long time, preventing them from separating.

[0038] In this embodiment, the outer sealing body 12 includes an upper sealing lip 121 and a lower sealing lip 122 distributed vertically, forming a negative pressure cavity 14 between the upper sealing lip 121 and the lower sealing lip 122 in a sealed state. The outer diameter of the upper sealing lip 121 gradually decreases from top to bottom, and the longitudinal cross-section of the upper sealing lip 121 is an upwardly extending inclined strip. The lower sealing lip 122 is fitted outside the plurality of elastic sheets 221, and the outer diameter of the lower sealing lip 122 gradually decreases from top to bottom. The longitudinal cross-section of the upper sealing lip 121 is also an upwardly extending inclined strip. The transition body 13 is located between the bottom of the upper sealing lip 121 and the top of the inner sealing body 11, and fits above the deformation space. The anti-retraction plate 123 is specifically disposed at the bottom of the inner side surface of the lower sealing lip 122.

[0039] In this embodiment, the inner sealing body 11 has inner and outer walls, and an annular cavity with an opening at the lower end is formed between the two walls. The inner support body 21 is at least partially housed in the annular cavity. The upper end of the inner sealing body 11 is provided with a limiting step surface 111 for installation limiting.

[0040] A sealing component of the present invention can be applied to a lifting basin, such as... Figures 4-10 As shown, the plurality of elastic sheets 221 improve the elastic deformation capability of the sealing gasket 1, thereby enabling the sealing component of the present invention to reduce wear and improve water sealing performance when applied to dynamic sealing. Specifically, the dynamic sealing process of the present invention is described below.

[0041] Please see Figures 4-10 As shown, a lifting basin of the present invention includes a basin base 3, a lifting component, and a driving mechanism. The basin base 3 has a basin cavity 31 that extends vertically. The lifting component is slidably disposed in the basin cavity 31 along the height direction and is adapted to surround the periphery of the basin cavity 31 to form a water storage tank. The driving mechanism is disposed on the basin base 3 and is adapted to drive the lifting component to rise or fall. The lifting component includes a base 4 and a sealing component as described above. The sealing component is fitted into an annular groove 41 provided on the outer periphery of the base 4, and the inner wall of the inner sealing body 11 abuts against the outer side of the base 4, and the outer sealing body 12 abuts against the cavity wall of the basin cavity 31.

[0042] In this embodiment, a guide mechanism is provided between the base 4 and the basin seat 3. This guide mechanism includes multiple sets of guide components, each comprising a guide post 5 and a guide sleeve 6. One of the guide post 5 and the guide sleeve 6 is fixed to the base 4, and the other is fixed to the basin seat 3. The guide sleeve 6 and the guide post 5 are slidably connected together along the lifting direction of the lifting component. The number of guide components is specifically three, but not limited to this; the three sets of guide components are arranged in a triangular pattern. The multi-angled support allows the base 4 to receive force at multiple points, resulting in more stable lifting movement.

[0043] In this embodiment, the bottom of the pelvic cavity 31 is provided with an inner flange 311. The top of the guide sleeve 6 is fixedly inserted through the inner flange, and the bottom of the guide sleeve 6 is fixedly connected to a fixing plate 72 provided on the driving mechanism. This ensures that the guide sleeve 6, fixing plate 72, basin seat 3, and base 4 are all on the same reference, allowing the base 4 to slide smoothly up and down along the basin seat 3. Specifically, the top of the guide sleeve 6 is inserted through the inner flange 311 of the pelvic cavity 31 and locked with two nuts 61. Figure 9 As shown, the bottom of the guide sleeve 6 is threaded to the fixing plate 72. The top of the guide post 5 is fixedly connected to the base 4. Specifically, the top of the guide post 5 is locked to the base 4 with screws 51, but it is not limited to this.

[0044] In this embodiment, the driving mechanism includes a lifting motor 7. The body of the lifting motor 7 is located below the basin cavity 31. The output shaft of the lifting motor 7 faces upward and is fixedly connected to the middle of a polygonal bracket. Each end of the polygonal bracket is fixedly connected to the base 4. The polygonal bracket is specifically a triangular bracket 8, but is not limited to this. The body of the lifting motor 7 is specifically fixed to a motor base 71. The motor base 71 is fixedly connected to the base plate 32 of the basin seat 3 and is fixedly fitted together with the fixing plate 72. The control panel 9 of the lifting motor 7 is provided on the countertop of the basin seat 3, and a basin faucet 20 is installed thereon.

[0045] In this embodiment, the lifting component further includes a cover plate 10, which is connected to the upper end of the base 4, and a drainage gap exists between the two. The base 4 is provided with a drainage hole (not shown in the figure) communicating with the drainage gap, and the drainage hole is equipped with a drainage control mechanism.

[0046] The present invention provides a liftable basin, which has two usage states. The first usage state is as follows: Figure 8 , Figure 9 As shown, at this time, the lifting component is at the lower part of the pelvic cavity 31, and together with the surrounding walls of the pelvic cavity 31, it forms a water storage tank; under the elastic force of each elastic sheet 221, the upper sealing lip 121 and the lower sealing lip 122 of the outer sealing body 12 abut against the surrounding walls of the pelvic cavity 31, forming two seals, and a negative pressure cavity is formed between the upper sealing lip 121, the lower sealing lip 122 and the cavity wall of the pelvic cavity 31, so that the entire outer sealing body 12 will be adsorbed on the cavity wall of the pelvic cavity 31, thereby forming an effective seal. The second usage state is as follows. Figure 10 At this time, the lifting component is positioned at the height of the basin cavity 31, and the cover plate is slightly lower than the surface of the basin seat 3. The lifting component, when raised, compensates for the limited storage space around the basin seat 3. The lifting component is driven by the lifting motor 7, enabling the switching between the two usage states. During the lifting process, the outer sealing body 12 is compressed by the cavity wall of the basin cavity 31, causing the linked elastic plate 221 to elastically swing towards the deformation space, creating clearance. This reduces the sliding friction between the sealing gasket 1 and the cavity wall of the basin cavity 31, resulting in smoother lifting and lowering of the component. It also reduces wear on the sealing gasket 1, extending its service life and ensuring a longer-lasting and effective water sealing effect. During the lifting process, the top of the upper sealing lip 121 of the outer sealing body 12 can simultaneously scrape away dirt adhering to the cavity wall of the basin cavity 31, achieving a clean basin cavity 31. When the lifting component rises or falls to its position, the outer sealing body 12 adheres tightly to the cavity wall of the basin 31 under the elastic force of the elastic sheet 221, achieving the best sealing effect.

[0047] The present invention provides a lifting basin, wherein the sealing component is enhanced with a sealing bracket 2, which on the one hand increases the support effect on the sealing gasket 1, reduces wear, and improves the water sealing effect, and on the other hand allows for a larger design tolerance of the basin.

[0048] The sealing component and lifting basin of the present invention, the parts not mentioned (such as the drainage control mechanism, etc.) are the same as or can be implemented by existing technology.

[0049] The above embodiments are only used to further illustrate a sealing component and a lifting basin of the present invention. However, the present invention is not limited to the embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the technical solution of the present invention.
