[0044] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0045] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, inside, outside, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0046] In the description of the utility model, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0047] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0048] In the related art, basins of different specifications often have different depths, so the heights of their overflow water levels will also be different. Existing drainage devices can usually only adapt to basins corresponding to their specifications, and it is difficult to meet the overflow water level requirements of various basins for different heights, limiting the application scope of drainage devices on different types of basins.

[0049] To this end, some embodiments of the present invention provide a drainage device 1000, specifically referring to the drawings of the specification. Figure 1-Figure 15 shown.

[0050] Reference Figure 1 and Figure 2 As shown, in the embodiment of the utility model, the drainage device 1000 may include: a base 100 and a water sealing assembly 200, wherein the base 100 may be used to be fixedly connected to the basin 2000 to achieve the installation of the drainage device 1000. In this embodiment, the basin 2000 equipped with the drainage device 1000 may have drainage function, water storage function and overflow function at the same time. Fig.15As shown, in the embodiment of the utility model, the basin 2000 may include a basin cavity 2200 and a mounting tank body 2100 that are interconnected, so the water level in the basin cavity 2200 is the same as the water level in the mounting tank body 2100. The drainage device 1000 may be installed in the mounting tank body 2100, based on which the water flow in the basin cavity 2200 may flow to the mounting tank body 2100 to achieve drainage or overflow.

[0051] Reference Figure 1 , Figure 2 and Figure 3 As shown, in the embodiment of the utility model, the base 100 can be used for connection and fixation with the table 2000, so as to realize the installation of the drainage device 1000. Specifically, the base 100 may include a connecting portion 110 and a drainage portion 120 that are interconnected. It should be noted that the connecting portion 110 and the drainage portion 120 may be hollow structures, and the interiors of the two may be interconnected. In this embodiment, the connecting portion 110 and the drainage portion 120 may be integrally formed, and the connecting portion 110 may be arranged at the upper end of the drainage portion 120. Among them, the peripheral wall of the connecting portion 110 may be provided with a drainage port 111, and the number of the drainage ports 111 may be selected and set according to actual conditions, and this embodiment does not limit this. A drainage cavity 121 may be provided inside the drainage portion 120. It is understood that the drainage port 111 may penetrate the peripheral wall of the connecting portion 110 so as to be communicated with the interior of the connecting portion 110, and then may be communicated with the drainage cavity 121. It is understood that the drainage port 111 and the drainage cavity 121 may form a drainage waterway. When the drainage waterway is connected, the water in the basin 2000 can be discharged through the drainage waterway, realizing the drainage function of the basin 2000; when the drainage waterway is blocked, the water in the basin 2000 can accumulate, realizing the water storage function of the basin 2000. It should be noted that the embodiment of the utility model does not limit the flow direction of the water in the drainage waterway.

[0052] Reference Figure 1 , Figure 2 and Figure 3As shown, in the embodiment of the utility model, the water sealing assembly 200 can be used to open and close the drainage waterway, and the water sealing assembly 200 can be arranged in the connection part 110, and can move along the axial direction of the base 100 to open and close the drainage waterway. Specifically, the water sealing assembly 200 may include an overflow pipe 210, a drainage pipe 220 and a water retaining member 230, wherein the overflow pipe 210 is sleeved on the drainage pipe 220 and can move along the axial direction of the drainage pipe 220, and the peripheral wall of the overflow pipe 210 is provided with an overflow port 211. In this embodiment, the overflow pipe 210 may be a hollow structure, and the overflow port 211 may penetrate the peripheral wall of the overflow pipe 210 to communicate with the inside of the overflow pipe 210. It should be noted that the overflow pipe 210 can have an active state and a locked state. When the overflow pipe 210 is in the active state, the overflow pipe 210 can move along the axial direction of the drain pipe 220, thereby changing the distance between the overflow port 211 and the base 100, and adjusting the distance between the two to adjust the overflow water level of the basin 2000; when the overflow pipe 210 is in the active state, the overflow pipe 210 can be relatively fixed to the drain pipe 220.

[0053] Reference Figure 2 , Figure 3 and Figure 4 As shown, in the embodiment of the utility model, an overflow cavity 221 may be provided inside the drain pipe 220, and a water outlet 222 communicating with the drain cavity 121 may be provided on the peripheral wall of the drain pipe 220. It is understandable that the water outlet 222 may penetrate the peripheral wall of the drain pipe 220, so when the water sealing assembly 200 is penetrated through the base 100, one end of the water outlet 222 may communicate with the overflow cavity 221, and the other end may communicate with the drain cavity 121. It should be noted that when the overflow pipe 210 is sleeved on the drain pipe 220, the water outlet 222 may always be located at the lower side of the overflow pipe 210. The overflow port 211, the overflow chamber 221, the water outlet 222 and the drainage chamber 121 can form an overflow waterway. Based on this, when the basin 2000 is in a water storage state and the water level is higher than the overflow port 211, the water can overflow through the overflow waterway, thereby realizing the overflow function of the basin 2000 and preventing the water from overflowing the basin 2000.

[0054] Reference Figure 2 , Figure 3 and Figure 4 As shown, in the embodiment of the utility model, the water retaining member 230 can be sleeved on the drain pipe 220, and the water retaining member 230 can block the flow of water. Specifically, refer to Figure 3 As shown, the water retaining member 230 may be a water retaining sheet, referring to Figure 5 As shown, the water retaining member 230 may also be a sealing ring, or other forms of water retaining components. Those skilled in the art may select and set the water retaining member according to actual conditions, and this embodiment does not limit this.

[0055] In the embodiment of the present utility model, the water sealing assembly 200 can have a first position and a second position, and the water sealing assembly 200 can move along the axial direction of the base 100 to switch between the first position and the second position, wherein, with reference to Figure 4 As shown, when the water sealing assembly 200 is located in the first position, since the water retaining member 230 moves into the connecting portion 110 driven by the drain pipe 220, the inner diameter of the connecting portion 110 is larger than the outer diameter of the water retaining member 230. Therefore, the drainage waterway is connected, and the water in the basin 2000 can enter the interior of the connecting portion 110 through the drain port 111, thereby flowing to the drainage cavity 121. At the same time, the water stored in the connecting portion 110 can also flow to the drainage cavity 121 from the gap between the water retaining member 230 and the inner wall of the connecting portion 110.

[0056] Reference Figure 3 As shown, when the water sealing assembly 200 is in the second position, the water retaining member 230 moves into the drainage cavity 121 driven by the drain pipe 220. The outer diameter of the elastic water retaining member 230 is larger than the inner diameter of the drainage portion 120. Therefore, the water retaining member 230 can abut against the inner wall of the drainage portion 120, thereby blocking the drainage waterway and switching the basin 2000 to the water storage state. When the water level in the basin 2000 is higher than the height of the overflow port 211, the water can overflow through the overflow waterway. It should be noted that Figure 3 and Figure 4 The arrow in the middle indicates the direction of water flow.

[0057] The embodiment of the utility model connects the drain port 111 and the drain cavity 121 to form a drain waterway, and then sets a water sealing component 200 so that when the water sealing component 200 is in the first position, water can flow out of the drain waterway through the drain port 111 and the drain cavity 121 in sequence, so that the water in the basin 2000 can be discharged through the drain waterway, thereby realizing the drainage function of the basin 2000; when the water sealing component 200 is in the second position, the water blocking member 230 abuts against the inner wall of the drain portion 120 to block the water flow to the drain waterway of the drain cavity 121, so that the water in the basin 2000 can accumulate, thereby realizing the water storage function of the basin 2000; by forming an overflow waterway with the overflow port 211, the overflow cavity 221, the water outlet 222 and the drain cavity 121, when the basin 2000 is in the water storage state and the water level is higher than the overflow port 211, the water flow The water can overflow through the overflow water channel, thereby realizing the overflow function of the basin 2000 and preventing the water from overflowing the basin 2000; by setting the overflow pipe 210 on the drain pipe 220 and enabling it to move along the axial direction of the drain pipe 220, the distance between the overflow port 211 and the base 100 can be adjusted, that is, the height of the overflow port 211 can be adjusted, so that the drainage device 1000 has the function of adjusting the overflow water level, and then the drainage device 1000 can be applied to basins 2000 with overflow water levels of different heights, so that the drainage device 1000 can meet the overflow requirements of basins 2000 of different specifications, ensuring that the drainage device 1000 can effectively control the overflow water level in various usage scenarios, solving the compatibility problem of the drainage device 1000, greatly improving the applicability of the drainage device 1000, and enhancing the user experience.

[0058] Reference Figure 2 and Fig.11 As shown, in the embodiment of the utility model, the overflow pipe 210 may be provided with a plurality of elastic arms 212 at one end close to the drain pipe 220, and the plurality of elastic arms 212 may be arranged at intervals along the circumference of the overflow pipe 210. It should be noted that the elastic arm 212 may move toward or away from the central axis of the overflow pipe 210, and the elastic arm 212 has the potential energy to move away from the central axis of the overflow pipe 210. It can be understood that when all the elastic arms 212 move toward the central axis of the overflow pipe 210 under the action of an external force, the overflow pipe 210 may clamp the drain pipe 220, thereby achieving relative fixation of the two. In the present embodiment, each elastic arm 212 may be provided with a buckle portion 2121, and the buckle portion 2121 may be arranged on the inner side of the elastic arm 212, and specifically, the buckle portion 2121 may protrude toward the central axis of the overflow pipe 210. When the elastic arm 212 moves toward the central axis of the overflow pipe 210 , it can drive the buckle portion 2121 to move toward the peripheral wall of the drain pipe 220 .

[0059] Reference Figure 2 , Figure 3 and Figure 4As shown, in an embodiment of the utility model, the outer peripheral wall of the drain pipe 220 may be provided with a plurality of slots 223 arranged at intervals along the axial direction of the drain pipe 220, and the slots 223 match the buckle portion 2121. Therefore, when the buckle portion 2121 moves toward the peripheral wall of the drain pipe 220, it can enter the slots 223 and be snapped into the slots 223. Specifically, the water sealing assembly 200 may further include a compression sleeve 240 sleeved on the outer peripheral wall of the overflow pipe 210. The compression sleeve 240 can move along the axial direction of the overflow pipe 210. Specifically, when the compression sleeve 240 moves upward, the elastic arm 212 can move away from the central axis of the overflow pipe 210; conversely, when the compression sleeve 240 moves downward, the compression sleeve 240 can tighten each elastic arm 212 so that the elastic arm 212 can move toward the central axis of the overflow pipe 210, thereby driving the elastic arm 212 to move toward the outer peripheral wall of the drain pipe 220, so that the buckle portion 2121 is engaged with one of the slots 223, thereby achieving relative fixation of the overflow pipe 210 and the drain pipe 220.

[0060] Reference Figure 6 and Figure 8 As shown, in the embodiment of the utility model, the outer peripheral wall of the drain pipe 220 may be provided with a plurality of snap rings 224 arranged at intervals along the axial direction of the drain pipe 220. Specifically, the snap rings 224 are arranged to extend around the circumference of the drain pipe 220. It can be understood that the snap rings 224 can be arranged to extend outward from the surface of the outer peripheral wall of the drain pipe 220. Based on this, adjacent snap rings 224 can be arranged to form a clamping groove 223. In an example, the snap ring 224 can be arranged to extend outward along the radial direction of the drain pipe 220. Correspondingly, the buckle part 2121 can also be arranged to extend along the radial direction of the overflow pipe 210. Through the clamping connection between the buckle part 2121 and each of the clamping grooves 223 arranged at intervals along the axial direction of the drain pipe 220, the step-by-step adjustment of the overflow pipe 210 is realized, the possibility of the overflow pipe 210 moving due to misoperation when the overflow pipe 210 and the drain pipe 220 are relatively fixed is reduced, and the stability of the overflow pipe 210 and the drain pipe 220 is improved.

[0061] Reference Figure 6 As shown, in another example, a plurality of snap rings 224 can be arranged obliquely and connected to each other to form an external thread, that is, the outer peripheral wall of the drain pipe 220 can be provided with an external thread, and the snap ring 224 can be the screw thread of the external thread. Correspondingly, the buckle portion 2121 can be an intermittent or continuous internal thread, thereby realizing the threaded connection between the buckle portion 2121 and the external thread. It should be noted that the outer peripheral wall of the drain pipe 220 can be provided with a single thread or a double thread, which is not limited in this embodiment. In the embodiment of the utility model, the overflow pipe 210 and the drain pipe 220 can be connected by threads, so that the adjustment of the distance between the overflow port 211 and the drain pipe 220 is more convenient and quick.

[0062] Reference Figure 7As shown, in another example, the outer peripheral wall of the drain pipe 220 may be further provided with a limiting column 225, the limiting column 225 may be penetrated through each thread in the external thread, a plurality of limiting columns 225 may be provided, and a plurality of limiting columns 225 may be arranged at intervals around the circumference of the drain pipe 220. It is understandable that when the overflow pipe 210 rotates a certain angle, the limiting column 225 may abut against the buckle portion 2121, thereby limiting the overflow pipe 210 from continuing to rotate, reducing the risk that the overflow pipe 210 is rotated by mistake and the overflow port 211 cannot be at the expected height, and improving the accuracy of the position adjustment of the overflow pipe 210.

[0063] Reference Fig. 9 and Fig.10 As shown, in the embodiment of the utility model, the outer peripheral wall of the drain pipe 220 may be provided with a plurality of clamping assemblies 226, and the plurality of clamping assemblies 226 may be arranged at intervals along the axial direction of the drain pipe 220, wherein each clamping assembly 226 may include a plurality of steps 2261 arranged at intervals along the circumference of the drain pipe 220, and specifically, the steps 2261 may protrude outwardly 2262 from the surface of the outer peripheral wall of the drain pipe 220. Based on this, two steps 2261 adjacent to each other along the axial direction of the drain pipe 220 may be surrounded to form a clamping groove 223. Since there is a gap between two steps 2261 adjacent to each other along the circumference of the drain pipe 220, a slideway 2263 may be formed between two steps 2261 adjacent to each other along the circumference of the drain pipe 220. When the buckle portion 2121 is screwed into between two adjacent steps 2261 along the axial direction of the drain pipe 220 , it can be locked in the slot 223 ; when the buckle portion 2121 is screwed out of the slot 223 , it can enter the slideway 2263 to move along the axial direction of the drain pipe 220 .

[0064] Reference Fig. 9 and Fig.10 As shown, in the embodiment of the utility model, at least one end of the step 2261 along the circumference of the drain pipe 220 may be provided with a protrusion 2262. Specifically, the step 2261 may be extended along the axial direction of the drain pipe 220 to limit the buckle portion 2121 from sliding out of the slot 223. For example, the protrusion 2262 may be extended downward, and the protrusion 2262 and another step 2261 located at the lower side thereof have a gap for the buckle portion 2121 to pass through. In this embodiment, the step 2261 may be provided with the protrusion 2262 only at one end, or at both ends. It is understood that when the buckle portion 2121 is engaged with the slot 223, the protrusion 2262 can limit the buckle portion 2121, thereby reducing the risk that the overflow pipe 210 is rotated by mistake and the overflow port 211 cannot be at the expected height, and improving the accuracy of the position adjustment of the overflow pipe 210.

[0065] Reference Figure 2 , Figure 3 and Fig.12As shown, in the embodiment of the utility model, the water sealing component 200 may further include a water sealing member 250 sleeved on the drain pipe 220, and the water sealing member 250 may be located at the upper part of the drain pipe 220. When the overflow pipe 210 is sleeved on the drain pipe 220, the water sealing member 250 may be located between the overflow pipe 210 and the drain pipe 220. Specifically, the outer peripheral wall of the water sealing member 250 may be inclined toward the overflow pipe 210 in a direction away from the overflow port 211, and abut against the inner wall of the overflow pipe 210, thereby reducing the possibility of premature overflow caused by the water located inside the connecting portion 110 flowing from the gap between the overflow pipe 210 and the drain pipe 220 to the overflow channel, and preventing the basin 2000 from being unable to store water to the expected water level.

[0066] Reference Figure 1 , Figure 2 and Figure 3 As shown, in the embodiment of the utility model, the drainage device 1000 may further include a pressing member 260, and the peripheral wall of the pressing member 260 may be provided with a protrusion 261, and the protrusion 261 may be extended outward from the peripheral wall surface of the lower end of the pressing member 260. The overflow pipe 210 may be provided with a through groove 213 matching the protrusion 261. Based on this, when the lower end of the pressing member 260 is penetrated in the overflow pipe 210, the protrusion 261 may be engaged with the through groove 213 to achieve a fixed connection between the pressing member 260 and the overflow pipe 210. It is understandable that the user can drive the water sealing assembly 200 to move along the axial direction of the base 100 by pressing the pressing member 260, so that it switches between the first position and the second position. In this embodiment, the lower end of the drain pipe 220 can be connected to the elastic component 500, and the elastic component 500 can improve the pressing feel of the pressing member 260, providing a better experience for the user.

[0067] Reference Fig.13 , Fig.14 and Fig.15 As shown, the embodiment of the utility model also proposes a basin 2000, including the drainage device 1000 of the above embodiment. Specifically, the basin 2000 may include a basin cavity 2200 and a mounting groove 2100 that are interconnected, and the drainage device 1000 is installed in the mounting groove 2100. Based on this, the drainage device 1000 may also include a limiter 400, which may be sleeved on the overflow pipe 210. The limiter 400 may prevent the drainage device 1000 installed in the mounting groove 2100 from tilting, and may also reduce the risk of the drainage device 1000 colliding with the inner wall of the mounting groove 2100 and being damaged, and reduce the possibility of leakage of the drainage device 1000 due to installation deviation.

[0068] The basin 2000 adopts the drainage device 1000 of the first embodiment. The basin 2000 communicates the drainage port 111 with the drainage cavity 121, and then sets a water sealing component 200. When the water sealing component 200 is in the first position, water can flow out through the drainage port 111 and the drainage cavity 121 in sequence, so that the water in the basin 2000 can be discharged, thereby realizing the drainage function of the basin 2000; when the water sealing component 200 is in the second position, the water blocking member 230 abuts against the inner wall of the drainage portion 120 to block the water flow to the drainage cavity 121, so that the water in the basin 2000 can accumulate, thereby realizing the water storage function of the basin 2000; the overflow port 211, the overflow cavity 221, the water outlet 222 and the drainage cavity 121 form an overflow waterway When the basin 2000 is in a water storage state and the water level is higher than the overflow port 211, the water can overflow through the overflow waterway, thereby realizing the overflow function of the basin 2000 and preventing the water from overflowing the basin 2000; by setting the overflow pipe 210 on the drain pipe 220 and enabling it to move along the axial direction of the drain pipe 220, the distance between the overflow port 211 and the base 100 can be adjusted, that is, the height of the overflow port 211 can be adjusted, so that the basin 2000 has the function of adjusting the overflow water level, so that the user can dynamically adjust the overflow water level according to the current use needs or usage scenarios, reducing the risk of overflow of the basin 2000, increasing the usage scenarios of the basin 2000, making the basin 2000 have higher usage flexibility, and improving the user experience.

[0069] Since the basin 2000 adopts all the technical solutions of the drainage device 1000 of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here.

[0070] Reference Figure 1 , Figure 2 and Figure 3 As shown, in the embodiment of the present invention, the outer peripheral wall of the drainage portion 120 may be provided with a locking portion 130 extending outward. The drainage device 1000 may also include a locking member 300, and the locking member 300 and the drainage portion 120 may be threadedly connected, that is, the locking member 300 may be close to the locking portion 130 or the locking portion 130 along the axial direction of the drainage portion 120. Based on this, referring to Fig.14 and Fig.15As shown, the installation groove 2100 is provided with an installation hole 2110, the drainage part 120 can be inserted into the installation hole 2110, and the clamping part 130 can abut against the bottom wall of the installation groove 2100, so when the locking member 300 moves toward the clamping part 130, the locking member 300 and the clamping part 130 can cooperate to clamp the basin 2000, thereby achieving a firm fixation of the drainage device 1000. In this embodiment, in order to prevent damage to the clamping part 130 and the locking member 300, a sealing gasket 140 can be further provided between the clamping part 130 and the bottom wall of the installation groove 2100 and between the locking member 300 and the basin 2000, which not only improves the sealing performance of the drainage device 1000, but also protects the clamping part 130 and the locking member 300.
