Description

Technical Field

[0001] This utility model belongs to the technical field of kitchen and bathroom products, and more specifically refers to a water-holding device that can control water holding and drainage. Background Technology

[0002] Currently, common water-holding devices, such as washbasins in bathroom fixtures, are examples. Figure 1 As shown, it mainly consists of a basin body 1 and a drainer. The top surface of the basin body 1 is recessed to form a water-holding space 2, and a drain hole 3 is formed at the lowest point of the inner circumference of the water-holding space 2. The top edge of the drain hole 3 is recessed with a mounting groove 4 with a diameter larger than the drain hole 3. In this way, the drain hole 3 can be used to install the drainer, and a flange protruding from the periphery of the drainer abuts against the mounting groove 4 to achieve the effect of positioning the drainer.

[0003] However, in the aforementioned water-holding device, since the flange of the drain abuts against the mounting groove 4 of the basin 1, and the mounting groove 4 is adjacent to the water-holding space 2, the flange of the drain is adjacent to the inner circumferential surface of the water-holding space 2. Therefore, when the water-holding space 2 becomes dirty due to the user washing hands or cleaning utensils, the flange of the drain will come into contact with the dirt in the water-holding space 2. And because the flange abuts against the mounting groove, over time, dirt will accumulate in the gaps around the flange and the mounting groove. When the flange of the drain is metal, rust spots will also appear. This not only makes the user feel disgusted and uncomfortable visually, but the dirt or rust spots on the flange also come into contact with the water contained in the water-holding space 2, thus indirectly contacting the user's wet body parts, which can easily cause skin discomfort to the user. Utility Model Content

[0004] In view of this, in order to improve the prior art, the area around the drain of the conventional water-holding device is prone to dirt accumulation, which can cause nausea, discomfort and skin irritation to the user; therefore, this utility model provides a water-holding device that can hold and drain water and prevent the user from seeing and indirectly contacting the dirt around the drain, thereby avoiding visual or skin discomfort.

[0005] The present invention provides a water-holding device comprising:

[0006] The basin has a main body, a water-holding space, a top hole, a bottom hole, and a step. The water-holding space is formed by a depression from the top surface of the main body downwards. The top hole is formed by a depression from the bottom of the inner circumference of the water-holding space downwards. The bottom hole extends upwards from the bottom surface of the main body. The bottom hole communicates with the top hole. The diameter of the top hole is different from the diameter of the bottom hole. The step is formed between the top hole and the bottom hole.

[0007] The drain has a flange body, a spring-loaded core, a water-stop pressure cap, and a locking nut. The flange body is placed in the bottom hole of the basin. The top of the flange body extends to the side with a contact portion that abuts against the step. The spring-loaded core is located inside the flange body. The water-stop pressure cap is connected to the top of the spring-loaded core. The locking nut is locked around the bottom of the flange body and abuts against the bottom surface of the basin body. When the spring-loaded core is pressed by an external force, it causes the water-stop pressure cap to move up and down to open or close the top hole.

[0008] Furthermore, the diameter of the top hole is larger than the diameter of the bottom hole.

[0009] Furthermore, the basin has an expansion groove that extends from the periphery of the step outwards.

[0010] Furthermore, the basin body has an overflow hole located near a high position on the inner circumference of the water-filling space of the basin body. The overflow hole extends into the circumferential wall of the basin body and extends downward into the circumferential wall of the basin body until it communicates with the expansion groove and the bottom hole.

[0011] Furthermore, the drainer has an upper sealing gasket that abuts against the abutting portion and the step portion.

[0012] Furthermore, the drainer also features a water-stop washer that surrounds the area below the top of the water-stop gland.

[0013] Furthermore, the drainer has a lower sealing gasket that presses against the locking nut and the bottom surface of the basin body.

[0014] Furthermore, the diameter of the bottom hole is larger than the diameter of the top hole.

[0015] In the above solution, the contact part is not against the perimeter of the top hole, but is hidden so that the user cannot see it. Therefore, the user will not experience visual nausea or discomfort. In addition, when the water-stop cap closes the top hole, even if there are stains on the contact part, because the contact part is not against the perimeter of the top hole, the water in the water-holding space will not come into contact with the contact part. The water that the user comes into contact with does not come into contact with the stains on the contact part, so the user will not indirectly come into contact with the stains, thus avoiding skin discomfort.

[0016] Another water-holding device provided by this utility model includes:

[0017] The basin has a main body, a water-holding space, a top hole, a bottom hole, a trough, and a step. The water-holding space is formed by a downward indentation from the top surface of the main body. The top hole is formed by a downward indentation from the bottom of the inner circumferential surface of the water-holding space. The bottom hole extends upward from the bottom surface of the main body and communicates with the top hole. The diameter of the top hole is the same as the diameter of the bottom hole. The trough is formed by the extension of the hole wall between the top hole and the bottom hole to the periphery. The step is formed between the trough and the bottom hole.

[0018] The drain has a flange body, a locking component, a spring-loaded core, a water-stop cap, and a locking nut. The flange body is placed in the bottom hole of the basin. The top of the flange body extends laterally with an abutment portion. The locking component is fitted onto the outer circumference of the flange body. The locking component has protruding protrusions on opposite sides, forming two opposing recessed portions between the two protrusions. The distance between the two protrusions is greater than the distance between the two recessed portions. The top surface of the protrusion of the locking component abuts against the abutment portion, while the bottom surface of the protrusion of the locking component abuts against the step portion. The spring-loaded core is located inside the flange body. The water-stop cap is connected to the top of the spring-loaded core. The locking nut is locked around the bottom of the flange body and abuts against the bottom surface of the basin body. When the spring-loaded core is pressed by external force, it causes the water-stop cap to move up and down to open or close the top hole.

[0019] Furthermore, the basin body has an overflow hole located near a high position on the inner circumference of the water-filling space of the basin body. The overflow hole extends into the circumferential wall of the basin body and extends downward into the circumferential wall of the basin body until it communicates with the expansion groove and the bottom hole.

[0020] Furthermore, the drainer has an upper sealing gasket that abuts against the locking member and the step.

[0021] Furthermore, the drainer also features a water-stop washer that surrounds the area below the top of the water-stop gland.

[0022] Furthermore, the drainer has a lower sealing gasket that presses against the locking nut and the bottom surface of the basin body.

[0023] Furthermore, the distance between the two protrusions is greater than the diameter of the top hole and the diameter of the bottom hole.

[0024] In addition to avoiding nausea and discomfort for users and preventing skin irritation, the above solution also reduces structural complexity and manufacturing costs by ensuring that the top and bottom holes have the same diameter, thereby enhancing market competitiveness.

Detailed Implementation

[0046] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0047] Please see Figures 2 to 8 This is a water-holding device 100 provided in the first embodiment of the present invention, which mainly includes a basin 10 and a drainer 20, wherein:

[0048] Please see Figures 2 to 4The basin 10 has a main body 11, a water-holding space 12, a top hole 13, a bottom hole 14, a step 15, a widened groove 16, and an overflow hole 17. The main body 11 is integrally formed. The water-holding space 12 is recessed downward from the top surface of the main body 11 to a predetermined depth and width for holding water or other liquids. The top hole 13 is recessed downward from the bottom of the inner circumferential surface of the water-holding space 12 to a predetermined depth. The bottom hole 14 extends upward from the bottom surface of the main body 11 to a predetermined depth. The bottom hole 14 communicates with the top hole 13, and the top hole diameter T of the top hole 13 is different from the bottom hole diameter t of the bottom hole 14. In this embodiment, the top hole 13... The aperture T of the hole is larger than the aperture t of the bottom hole 14, thereby forming the step 15 between the top hole 13 and the bottom hole 14. The expansion groove 16 extends from the periphery of the step 15 to the periphery. The overflow hole 17 is located near the high position on the inner circumferential surface of the water-filling space 12 of the basin body 11. The overflow hole 17 extends into the peripheral wall of the basin body 11 and extends downward into the peripheral wall of the basin body 11 until it communicates with the expansion groove 16 and the bottom hole 14. Preferably, the overflow hole 17 and the bottom hole 14 are connected by a pipe.

[0049] Please see Figures 2 to 6 The drain 20 includes a flange body 21, an upper sealing gasket 22, a spring-loaded core 23, a water-stopping gland 24, a water-stopping washer 25, a locking nut 26, and a lower sealing gasket 27. The flange body 21 is approximately a hollow cylindrical body, placed in the bottom hole 14 of the basin 10. The top of the flange body 21 extends circumferentially to the side and has a protruding abutment portion 211, which abuts against the step portion 15 to position the flange body 21 relative to the basin 10. The upper sealing gasket 22 abuts between the abutment portion 211 and the step portion 15 to achieve a water-stopping and leak-proof effect. The spring-loaded core 23 is disposed on the flange body 21. Inside 1, the water-stop pressure cap 24 is connected to the top of the spring core 23, the water-stop washer 25 is connected around the area below the top of the water-stop pressure cap 24, the locking nut 26 is locked around the bottom of the flange body 21 and abuts against the bottom surface of the basin body 11 of the basin body 10 to restrict the position of the flange body 21, and the lower sealing gasket 27 is pressed between the locking nut 26 and the bottom surface of the basin body 11 to achieve the effect of water-stopping and leak-proofing.

[0050] Therefore, the above is an introduction to the components and assembly method of the water holding device 100 provided in a preferred embodiment of the present utility model. Its usage features are then introduced below.

[0051] like Figure 6As shown, when the user presses down on the water-stop cap 24, the spring-loaded core 23 will descend, pulling the water-stop cap 24 down and pressing it against the top hole 13 of the basin body 10, thus sealing the top hole 13. At this time, the water-stop washer 25 is pressed into the top hole 13 and deformed by the peripheral wall of the top hole 13, achieving a better water-stopping and leak-proof effect. In this way, the water-holding space 12 can be used by the user to hold water 90 or other liquids, such as... Figure 6 As shown.

[0052] Next, when the user wants to drain the water from the water-filled space 12, the user presses the water-stop cap 24 once, causing the spring-loaded core 23 to move the water-stop cap 24 upwards, as shown. Figure 7 As shown, at this time, the top hole 13 is no longer sealed, so the water 90 in the water-holding space 12 will flow to the top hole 13 and the bottom hole 14. Figure 7 The arrows on both sides of the central top hole 13 indicate the direction of water flow. Finally, the water flows out through the tailpipe 28 connected to the flange body 21 until it flows out completely. Figure 8 As shown.

[0053] Therefore, in this invention, the abutment portion 211 of the flange body 21 abuts against the step 15 between the top hole 13 and the bottom hole 14, rather than against the area around the top hole 13. That is, the abutment portion 211 of the flange body 21 is not located on the inner circumferential surface of the water-filled space 12. Thus, the abutment portion 211 is hidden and not visible to the user, preventing visual discomfort or nausea. Furthermore, when the water-stop cap 24 seals the top hole 13, even if there are stains on the abutment portion 211, because it does not abut against the area around the top hole 13, the water in the water-filled space 12 will not come into contact with the abutment portion 211. The water that the user comes into contact with does not come into contact with the stains on the abutment portion 211, thus preventing indirect contact with the stains and avoiding skin irritation.

[0054] In addition, although the diameter of the top hole 13 is larger than that of the bottom hole 14 in the above embodiment, in reality, the diameter of the bottom hole 14 can also be larger than that of the top hole 13. As long as the assembly procedure of the drainer 20 is changed, the assembly can be completed in the same way to achieve the same effect.

[0055] Please see Figures 9 to 15 This is a water-holding device 200 provided in the second embodiment of the present invention, which mainly includes a basin 30 and a drainer 40, wherein:

[0056] Please see Figure 9 , Figures 12 to 15The basin body 30 has a basin body 31, a water-holding space 32, a top hole 33, a bottom hole 34, a step 35, a widened groove 36, and an overflow hole 37. The basin body 31 is integrally formed. The water-holding space 32 is formed by recessing a predetermined depth and width from the top surface of the basin body 31 for holding water or other liquids. The top hole 33 is formed by recessing a predetermined depth from the bottom of the inner circumferential surface of the water-holding space 32. The bottom hole 34 is formed by extending a predetermined depth from the bottom surface of the basin body 11. The bottom hole 34 communicates with the top hole 33, and the diameter T of the top hole 33 is the same as the diameter T of the bottom hole 34 (e.g., ...). Figure 12 As shown), the expansion groove 36 is formed by extending the portion of the hole wall between the top hole 33 and the bottom hole 34 outwards, thereby forming the step 35 between the expansion groove 36 and the bottom hole 34. The overflow hole 37 is located near the high position on the inner circumferential surface of the water-filling space 32 of the basin body 31. The overflow hole 37 extends into the circumferential wall of the basin body 31 and extends inwards until it communicates with the expansion groove 36 and the bottom hole 34. Preferably, the overflow hole 37 and the bottom hole 34 are connected by a pipe.

[0057] Please see Figures 9 to 11 The drain 40 includes a flange body 41, an upper sealing gasket 42, a spring-loaded core 43, a water-stop gland 44, a water-stop washer 45, a locking nut 46, a lower sealing gasket 47, and a locking member 48. The flange body 41 is approximately a hollow cylinder, placed in the bottom hole 34 of the basin 30. The top of the flange body 41 extends circumferentially to the side, protruding with an abutment portion 411. The locking member 48 is an annular ring, fitted around the outer circumference of the flange body 41. The top surface of the locking member 48 abuts against the abutment portion 411, while the bottom surface of the locking member 48 abuts against the step 35 of the basin 30, thus positioning the flange body 41 relative to the basin 30. The upper sealing gasket 42 is abutted against the locking member 48 and the step 35. To achieve a water-stopping and leak-proof effect, the spring-loaded core 43 is disposed inside the flange body 41, the water-stopping gland 44 is connected to the top of the spring-loaded core 43, the water-stopping washer 45 is connected around the bottom of the water-stopping gland 44, the locking nut 46 is locked around the bottom of the flange body 41 and abuts against the bottom surface of the basin body 31 of the basin 30 to restrict the position of the flange body 41, and the lower sealing gasket 47 is pressed between the locking nut 46 and the bottom surface of the basin body 31 to achieve a water-stopping and leak-proof effect. The locking member 48 has protruding protrusions 481 on opposite sides, forming two opposing recessed portions 482 between the two protrusions 481. The first distance D between the two protrusions 481 is greater than the second distance d between the two recessed portions 482 (e.g., ...). Figure 11 As shown), both the first distance D and the second distance d refer to straight-line distances, and the first distance D between the two protruding parts 481 is greater than the diameter T of the top hole 33 and the diameter T of the bottom hole 34 (as shown). Figure 12 (As shown). Therefore, the locking member 48 passes through the bottom hole 34 at an angle from bottom to top, and then is placed in a horizontal state, so that the top surface of the protrusion 481 of the locking member 48 abuts against the abutment 411, while the bottom surface of the protrusion 481 of the locking member 48 abuts against the step 35 of the basin 30.

[0058] Therefore, when the user presses down on the water-stop cap 44, the spring-loaded core 43 will descend, pulling the water-stop cap 44 down and pressing it against the top hole 43 of the basin 30, thus sealing the top hole 43. At this time, the water-stop washer 45 is pressed into the top hole 33 and deformed by the peripheral wall of the top hole 33, achieving a better water-stopping and leak-proof effect. In this way, the water-holding space 32 can be used by the user to hold water 90 or other liquids, such as... Figure 13 As shown.

[0059] When the user presses the water-stop cap 44 once, the spring-loaded core 43 causes the water-stop cap 44 to move upward, such as... Figure 14 As shown, the top hole 33 is no longer sealed at this time, so the water 90 in the water-filled space 32 will flow to the top hole 33 and the bottom hole 34. Figure 14 (The arrows on both sides of the central top hole 33 indicate the direction of water flow), and finally the water flows out through the tailpipe 49 connected to the flange body 41 until it flows out completely. Figure 15 As shown.

[0060] The second embodiment can achieve the same effect and purpose as the first embodiment. Since the second embodiment does not require the top hole and bottom hole to be designed with different diameters, a step cannot be naturally formed between the top hole and bottom hole with the same diameter. Therefore, it is necessary to set an expansion groove to form a step and add a locking component to form a technical solution with the same effect as the first embodiment with different diameters of top hole and bottom hole. This can reduce the manufacturing cost of the basin and thus enhance market competitiveness.

[0061] The above description is merely a preferred embodiment provided by this utility model and is not intended to limit the scope of implementation of this utility model. All equivalent changes made by those skilled in the art based on this utility model should fall within the scope of this utility model.
