Description

Technical Field

[0001] This invention relates to the field of bathroom fixtures, and in particular to a drain assembly and a lift-up basin. Background Technology

[0002] Washbasins are essential sanitary ware for people when washing up. With the advancement of technology, products are becoming increasingly intelligent, and people are pursuing smart products, including bathroom washbasins. Most washbasins on the market are fixed countertop or under-counter designs, which are increasingly unable to meet people's usage requirements and cannot adequately accommodate different heights, such as the elderly, children, and disabled people. Washbasins installed at the height of an average adult often leave these groups unable to reach them. To solve these problems, lift-up washbasins have begun to appear on the market and are bound to become a popular trend. However, inventing a matching drain system for them is a crucial issue that must be addressed.

[0003] Chinese utility model patent No. 202122854733.X discloses a lifting basin, which includes a drainage component (i.e., a drain assembly). This drainage component comprises a main body, a sealing element, and a rotating rod. The main body is fixedly connected to the base and has a drainage channel communicating with a drainage hole. The sealing element slides vertically within the drainage channel. The rotating rod is installed inside the main body, with a first swing part at one end and a second swing part at the other end. The first swing part extends into the drainage channel to support the sealing element. A sliding element is slidably installed inside the main body and configured to rotate the second swing part, thereby causing the first swing part to swing vertically. A drive assembly drives the sliding element to slide, thereby driving the sealing element to slide, thus blocking or opening the drainage hole. However, this drainage component has the following drawbacks: the structure is relatively complex, and the entire drainage component rises and falls with the base, increasing the overall weight of the base and thus increasing the load on the lifting motor. Furthermore, the long-term movement of the drainage component with the base can lead to poor stability of the entire drainage component, and loosening of components is likely to occur. Summary of the Invention

[0004] This invention addresses the technical problems existing in the prior art by providing a drain device and a lifting basin for a lifting basin, overcoming the problems of complex structure and poor stability of the drainage components in the prior art.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a drain device for a liftable basin, comprising a fixed base, a sliding tube, and a sealing assembly. The fixed base is provided with a guide channel and a drain outlet communicating with the guide channel. The guide channel extends in the vertical direction and has an opening at its upper end. The sliding tube has a water inlet at its top and a water outlet at its bottom, and the sliding tube is slidably fitted inside the guide channel of the fixed base. The sealing assembly is installed on the fixed base and is used to open or close the drain outlet.

[0006] Furthermore, the sealing assembly includes a piston and a driving member. The fixed base is also provided with a sliding channel for the piston. One axial end of the sliding channel leads to the bottom of the guide channel. The drain outlet is located on the side wall of the sliding channel. The piston sealing sleeve is inside the sliding channel. The driving member is located outside the sliding channel and connected to the piston to drive the piston to slide and open or close the drain outlet.

[0007] Furthermore, the driving component is a push rod motor, and the other end of the sliding channel is provided with an opening. The push rod motor is installed at the other end of the sliding channel, and its output shaft is fixedly connected to the piston.

[0008] Furthermore, the push rod motor is mounted at the other end of the sliding channel using a fixing assembly. The fixing assembly includes a pressure cap and a motor base. The pressure cap is threadedly connected to the other end of the sliding channel and confines the piston within the sliding channel. The motor base is fixedly connected to the pressure cap by screws. The push rod motor is mounted in the motor base.

[0009] Furthermore, it also includes a drain electronic switch, which is used to control whether the push rod motor works.

[0010] Furthermore, the fixed base is also provided with a drainage channel, the upper end of which is connected to the water trap under the base of the lifting basin, and the lower end of which is connected to the drain outlet.

[0011] Furthermore, a sealing ring is fitted between the sliding tube and the guide channel.

[0012] Furthermore, the mounting base is connected to a drain pipe, the inlet of which is connected to the drain outlet.

[0013] The present invention also provides a lifting basin, including a basin seat, a base, and a drive mechanism. The basin seat has a basin cavity that extends vertically. The base slides in a sealed manner 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 seat and is adapted to drive the base to rise or fall. The basin also includes a drain device as described above for the lifting basin of the present invention. The sliding tube is connected to or integrally formed with the base, and the inlet of the sliding tube is connected to the water storage tank.

[0014] Furthermore, the base has a flange at the bottom, which forms a water trap between the flange and the cavity wall of the basin. The fixing seat is also provided with a drain channel, the upper end of which is connected to the water trap, and the lower end of which is connected to the drain outlet.

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

[0016] 1. The drain assembly of the present invention includes a fixed base, a sliding tube, and a sealing assembly. The sliding tube is slidably fitted within the guide channel of the fixed base and can slide up and down. Therefore, the drain assembly of the present invention has a simpler structure than the drainage assembly of the prior art. Furthermore, when the drain assembly of the present invention is applied to a lift basin, only the sliding tube rises or falls with the base of the lift basin; the fixed base and the sealing assembly do not need to rise or fall with the base. Thus, the drain assembly of the present invention reduces the load on the lifting motor of the lift basin, making the movement smoother and more energy-efficient. On the other hand, it improves the overall stability of the drain assembly, making it less prone to loosening or detachment between components.

[0017] 2. The sealing assembly includes a driving component and a piston. The piston is slidable by the driving component to open or close the drain outlet, so as to store water and drain water. Its structure is simple and easy to manufacture.

[0018] 3. The preferred driving component is a push rod motor, enabling the invention to achieve electric control and thus making operation more convenient for the user. Specifically, the push rod motor is mounted at the other end of the sliding channel using the fixing assembly, which includes the pressure cap and the motor base, making the push rod motor very easy to assemble and disassemble.

[0019] 4. The present invention further includes a drainage electronic switch, which controls the water storage and drainage of the lifting basin, making it more convenient and user-friendly for users.

[0020] 5. The fixed base is also provided with a drainage channel. The upper end of the drainage channel is connected to the water trap under the base of the lifting platform basin. This allows the water in the water trap to be drained immediately through the drainage channel when the water in the water tank flows into the water trap due to poor sealing or improper assembly of the lifting platform basin. This prevents water from accumulating in the water trap for a long time, which can lead to the growth of bacteria and odor.

[0021] 6. A sealing ring is fitted between the sliding tube and the guide channel to form an effective seal between them, preventing water from overflowing from the gap between the sliding tube and the guide channel when the drainage flow is too large.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments; however, the drain device for the lifting basin and the lifting basin of the present invention are not limited to the embodiments. Attached Figure Description

Detailed Implementation

[0032] In this invention, the use of terms such as "up," "down," "left," and "right" 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.

[0033] Please see Figure 1 - Figure 8 As shown, a drain device for a liftable basin according to the present invention includes a fixed base 2, a sliding tube 1, and a sealing assembly 3. The fixed base 2 is provided with a guide channel 21 and a drain outlet 221 communicating with the guide channel 21. The guide channel 21 extends vertically and has an opening at its upper end. The sliding tube 1 has a water inlet at its top and a water outlet at its bottom. Specifically, the sliding tube 1 is vertically continuous, with the upper opening being the water inlet and the lower opening being the water outlet. The sliding tube 1 is slidably fitted within the guide channel 21 of the fixed base 2. The sealing assembly 3 is installed on the fixed base 2 and is used to open or close the drain outlet 221.

[0034] In this embodiment, the sealing assembly 3 includes a piston 31 and a driving member. The fixed base 2 also has a sliding channel 22 for the piston 31. One axial end of the sliding channel 22 (i.e., the left end of the sliding channel 22) leads to the bottom of the guide channel 21. The drain outlet 221 is located on the side wall of the sliding channel 22. Specifically, the sliding channel 22 is perpendicular to the guide channel 21, but is not limited thereto. The drain outlet 221 is located at the bottom of the sliding channel 22. The piston 31 is sealed and slidably fitted inside the sliding channel 22, and the driving member is located outside the sliding channel 22. The driving member is connected to the piston 31, driving the piston 31 to slide in the sliding channel 22, thereby opening or closing the drain outlet 221.

[0035] In this embodiment, the driving component is a push rod motor 32, but it is not limited to this. In other embodiments, the driving component is a purely mechanical drive mechanism or other electric drive mechanism. An opening is provided at the other end of the sliding channel 22 (i.e., the right end of the sliding channel 22). The push rod motor 32 is mounted on the other end of the sliding channel 22 (i.e., the right end of the sliding channel 22) using a fixing assembly, and its output shaft is fixedly connected to the piston 31. The fixing assembly includes a pressure cap 33 and a motor base 34. The pressure cap 33 has a through-hole in the middle, the diameter of which is smaller than the diameter of the piston 31 but larger than the diameter of the push rod motor 32. The pressure cap 33 is threadedly connected to the other end of the sliding channel 22 (i.e., the right end of the sliding channel 22). When connected to the sliding channel 22, it can confine the piston 31 within the sliding channel 22, preventing it from disengaging from the sliding channel 22 during sliding, and allowing the push rod motor 32 to pass through, driving the piston 31 to slide within the sliding channel 22. The motor base 34 is fixedly connected to the pressure cover 33 by screws, and the push rod motor 32 is installed in the motor base 34.

[0036] The sealing assembly 3 is installed as follows: the piston 31 is placed in the sliding channel 22, the pressure cap 33 is threadedly connected to the sliding channel 22, the push rod motor 32 is installed in the motor base 34, its output shaft is fixedly connected to the piston 31, and the motor base 34 is fixedly connected to the pressure cap 33 with screws, thus completing the installation of the sealing assembly 3.

[0037] In this embodiment, the drain device of the present invention also includes a drain electronic switch (not shown in the figure). The drain electronic switch is used to control whether the push rod motor 32 works or not. The user can press the drain electronic switch to control the push rod motor 32 to close or open the drain outlet 221 of the piston 31, so as to facilitate the user to store or drain water.

[0038] In this embodiment, the fixed base 2 is also provided with a drainage channel 23. The upper end of the drainage channel 23 is connected to the water trap 411 under the base of the lifting basin, and the lower end of the drainage channel 23 is connected to the drain outlet 221. When water flows into the water trap 411 due to poor sealing or improper assembly of the lifting basin, the water accumulated in the water trap 411 can be drained to the drain outlet 221 and discharged through the drainage channel 23.

[0039] In this embodiment, a sealing ring 8 is fitted between the sliding tube 1 and the guide channel 21 to seal the inner wall of the sliding tube 1 and the guide channel 21, preventing water from overflowing from the gap between the sliding tube 1 and the guide channel 21 due to excessive drainage flow during drainage.

[0040] In this embodiment, the fixed base 2 is connected to a drain pipe 7. The inlet of the drain pipe 7 is connected to the drain outlet 221. When the user drains water, the water flows into the drain pipe 7 through the drain outlet 221 and is finally discharged into the sewer through the drain pipe 7.

[0041] The present invention provides a drain device for a lift-up sink, which is applied to the lift-up sink as follows: Figures 3-7 As shown: The upper end of the sliding tube 1 is fixedly connected to (or integrally formed with) the base 5 of the lifting basin, and the fixed seat 2 is installed at the bottom of the basin cavity 41 of the basin base 4. The usage is as follows: When water needs to be stored, press the drain electronic switch, which controls the push rod motor 32 to drive the piston 31 to slide to the left, blocking the drain outlet 221. When drainage is needed, simply press the drain electronic switch again, and the push rod motor 32 will drive the piston 31 to move to the right, opening the drain outlet 221. The water in the water storage tank of the lifting basin flows through the sliding tube 1 into the sliding channel 22 of the fixed seat 2, then flows along the sliding channel 22 to the drain outlet 221, and finally is discharged from the drain pipe 7.

[0042] The drain device for a lift-up basin of the present invention has a simpler structure compared with the drainage components of existing lift-up basins. It only requires the piston 31 to slide and close or open the drain outlet 221 via the push rod motor 32 to complete water storage or drainage. Furthermore, in the drain device of the present invention, only the sliding pipe 1 rises or falls with the base 5 of the lift-up basin; the fixing seat 2 and the sealing assembly 3 do not need to rise or fall with the base 5. Therefore, the drain device of the present invention reduces the load on the lifting motor of the lift-up basin, resulting in smoother movement and lower energy consumption. It also improves the overall stability of the drain device, making it less prone to loosening or detachment of components.

[0043] Please see Figures 1-8 As shown, a lifting basin of the present invention includes a basin base 4, a base 5, and a driving mechanism. The basin base 4 has a basin cavity 41 that extends vertically. The base 5 slides in a sealed manner within the basin cavity 41 along the height direction and is adapted to form a water storage tank by surrounding the perimeter walls of the basin cavity 41. The driving mechanism is disposed on the basin base 4 and is adapted to drive the base 5 to rise or fall. The basin also includes a drain device for the lifting basin described above. The sliding tube 1 is connected to or integrally formed with the base 5, and the inlet of the sliding tube 1 communicates with the water storage tank. The fixed base 2 is installed on the basin base 4.

[0044] In this embodiment, the base 5 has a flange 412 at its lower part. Specifically, the flange 412 is located on the inner side of the bottom of the basin 41. The longitudinal section of the flange 412 is approximately L-shaped. A water trap 411 is formed between the flange 412 and the cavity wall of the basin 41. If the sealing component fitted around the outer periphery of the base 5 is not sealed properly or is not assembled correctly, water in the water tank will leak into the water trap 411. The fixing seat 2 is installed at the bottom of the basin 41 of the basin base 4: the upper end of the guide channel 21 of the fixing seat 2 passes upward through the flange 412 and is locked with a nut. The upper end of the drain channel 23 is sealed and fitted into the small hole corresponding to the lower part of the flange 412, such as... Figure 8 As shown, the upper end of the drain channel 23 is connected to the water trap 411. Therefore, when water in the water tank leaks into the water trap 411, the drain channel 23 will drain the water accumulated in the water trap 411, thereby preventing the water trap 411 from accumulating for a long time and causing bacteria growth, odor, etc.

[0045] In this embodiment, a guide mechanism is provided between the base 5 and the basin seat 4. This guide mechanism includes multiple guide components, each including a guide post 10 and a guide sleeve 11. One of the guide post 10 and the guide sleeve 11 is fixed to the base 5, and the other is fixed to the basin seat 4. The guide sleeve 11 and the guide post 10 are slidably connected together along the lifting direction of the base 5. Specifically, the top of the guide sleeve 11 is fixedly inserted through the flange portion 412, and the bottom of the guide sleeve 11 is fixedly connected to a fixing plate 13 provided on the drive mechanism. This ensures that the guide sleeve 11, the fixing plate 13, the basin seat 4, and the base 5 are all under the same reference, allowing the base 5 to slide smoothly up and down along the basin seat 4. The guide sleeve 11 is fixed to the flange portion 412 by inserting the top of the guide sleeve 11 through the flange portion 412 of the basin cavity 41 and locking it with two nuts. Figure 3 As shown, the bottom of the guide sleeve 11 is threadedly connected to the fixing plate 13. The top of the guide post 10 is fixedly connected to the base 5; specifically, the top of the guide post 10 is locked to the base 5 with screws, but this is not limited to this. The number of guide components is specifically three sets, but not limited to this, and the three sets of guide components are arranged in a triangular pattern. The setting of the guide mechanism can ensure that the lifting and lowering of the base is more stable.

[0046] In this embodiment, the driving mechanism includes a lifting motor 6. The body of the lifting motor 6 is located below the basin cavity 41. The output shaft of the lifting motor 6 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 5. The polygonal bracket is specifically a triangular bracket 12, but is not limited to this. The arrangement of the polygonal bracket allows the base 5 to receive force at multiple points, making the lifting movement more stable. The body of the lifting motor 6 is specifically fixedly connected to the base plate of the basin seat 4 and is fixedly fitted together with the fixing plate 13.

[0047] In this embodiment, the present invention also includes a cover plate 9, which is disposed on the upper end of the base 5 and has a drainage gap between it and the base 5. The drainage gap is connected to the upper water inlet of the sliding tube 1.

[0048] The present invention provides a liftable basin, which has two usage states. The first usage state is as follows: Figure 4 , Figure 5 As shown, at this time, the base 5 is located at the lower part of the pelvic cavity 41, and together with the surrounding walls of the pelvic cavity 41, forms a water storage tank; the piston 31 closes the drain outlet 221. When drainage is needed, the piston 31 opens the drain outlet 221, and the water in the water storage tank enters the sliding tube 1, and then flows along the sliding tube 1 into the fixed seat 2, and finally flows down the drain pipe 7 through the drain outlet 221, as shown. Figure 6 , Figure 7 As shown. The second usage state of the present invention is as follows. Figure 6 As shown, at this time, the base 5 is positioned at the height of the basin cavity 41, and the cover plate 9 is slightly lower than the countertop of the basin seat 4, which can be used for placing items, thereby compensating for the limited storage space around the countertop of the basin seat 4. During the process of the base 5 rising or falling, the sliding tube 1 also slides up or down along the guide channel 21 of the fixed seat 2, ensuring that the sliding tube 1 does not affect the raising or lowering of the base 5. The drain device and the lifting basin of the present invention are described below. The parts not described are the same as or can be implemented using existing technology.

[0049] The above embodiments are only used to further illustrate the drain device and 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.
