Description

Technical Field

[0001] This utility model relates to the field of water tank drainage technology, and in particular to a drainage connector and a water tank. Background Technology

[0002] Currently, some commercially available water tanks or aquariums have drain connectors installed at the bottom. A Chinese invention patent (patent application number: 201410453845.6) discloses a drain connector that uses an upper and lower sleeve at the aquarium's water outlet. The lower sleeve connects to a valve and a drain pipe, allowing water to be drained from the aquarium. The purpose of draining is also to better control the water level. However, with this solution, the amount of water drained depends on when the user connects the valve. Furthermore, since the valve is usually located at the top of the tank, it is inconvenient for the user to control the valve while observing the water level. In other words, using existing drain connectors is not convenient for users to drain water, and the control of the water level in the tank is neither precise nor convenient. Utility Model Content

[0003] The main purpose of this utility model is to provide a drainage connector that facilitates drainage for users while allowing for more precise control of the water level in the water tank.

[0004] To achieve the above objectives, the present invention proposes a drain connector for use in water tanks and overflow pipes, wherein the water tank forms a water storage tank, and the drain connector includes:

[0005] The main body is installed in the water tank and forms a drainage channel that connects to the water storage tank. The drainage channel penetrates the bottom wall of the water storage tank.

[0006] The stop-flow structure includes at least one lever, a connecting seat, and a plug. The connecting seat is connected to the body and forms a drain hole that connects to the drain channel. The plug can be partially inserted into the drain hole to separate the drain hole from the drain channel. The lever is connected to the connecting seat and the plug.

[0007] The overflow pipe can be inserted into the drainage channel and abut against the actuating rod, so that the actuating rod drives the plug to move upward, connecting the drainage hole and the drainage channel.

[0008] In an optional embodiment, the actuating rod includes a rod body connected to each other and a stop section and a connecting section connected to opposite sides of the rod body. The rod body is rotatably connected to the connecting seat, the connecting section is connected to the plug, and the overflow pipe can abut against the stop section.

[0009] In an optional embodiment, the plug is provided with a connecting waist-shaped hole, and the end of the connecting segment away from the rod body is recessed to form a connecting hole. The connector passes through the connecting waist-shaped hole and the connecting hole to connect the plug and the connecting segment.

[0010] In an alternative embodiment, the actuating rod further includes a torsion spring elastically connected to the rod body and the connecting seat, the torsion spring providing elastic force to allow the plug to be inserted into the drain hole.

[0011] In an optional embodiment, the stop structure further includes a water-proof ring, which is disposed around the side wall of the drain hole and elastically abuts against the plug.

[0012] In an optional embodiment, the stop structure includes two levers connected to the connecting seat and located on opposite sides of the plug.

[0013] In an optional embodiment, the outer surface of the connecting seat is provided with an external thread, the inner wall surface of the drainage channel is provided with an internal thread, and the connecting seat and the body are threadedly connected.

[0014] In an optional embodiment, the body includes a first connecting sleeve, a second connecting sleeve, a fixing seat, and an adjusting sleeve. The first connecting sleeve is connected to the water tank, the fixing seat is detachably connected to the first connecting sleeve, and the adjusting sleeve is detachably connected to the fixing seat. The adjusting sleeve abuts against the outer side of the second connecting sleeve to press the second connecting sleeve against the surface of the fixing seat.

[0015] In an optional embodiment, the body further includes a sealing gasket and a sealing ring. The sealing gasket is disposed on the fixing seat and elastically abuts against the lower surface of the water tank, and the sealing ring is disposed between the fixing seat and the second connecting sleeve.

[0016] This utility model also proposes a water tank, including a tank body, an overflow pipe and a drain connector. The drain connector is the drain connector as described above. The tank body forms a water storage tank and a through hole communicating with the water storage tank. The through hole is located at the bottom of the tank body. The drain connector is sleeved in the through hole. The overflow pipe can be inserted into the drain connector.

[0017] The drain connector of this utility model is applied to water tanks and overflow pipes. The water tank forms a water storage tank for storing water. The body of the drain connector is installed in the water tank and forms a drain channel that connects to the water storage tank. The drain channel penetrates the bottom wall of the water storage tank. The connecting seat of the stop structure is connected to the body and forms a drain hole that connects to the drain channel. The plug can be partially inserted into the drain hole to separate the drain hole and the drain channel. The pull rod is connected to the connecting seat and the plug.

[0018] In this application, under the action of its own gravity and the water pressure inside the tank, the plug is firmly inserted into the drain hole, preventing water from flowing out of the storage tank and maintaining the water level at a certain level. When drainage is needed to lower the water level, an overflow pipe of a certain length can be inserted from the storage tank into the drain channel. The wall of the overflow pipe abuts against the pull rod, which can drive the plug to move upward against its own force and water pressure, thereby connecting the drain hole and the drain channel, allowing water in the storage tank to flow outward through the drain channel and drain hole. Using the drain connector of this application, on the one hand, it can seal the storage tank, thus eliminating the need for an additional water valve. On the other hand, when draining, it is only necessary to insert the overflow pipe into the drain channel. Since the length of the overflow pipe is the height of the water level, it is not necessary to constantly observe the water level when the water flows outward, enabling relatively precise control of the water level. At the same time, drainage and water shut-off can be achieved simply by inserting and removing the overflow pipe, making the operation simple and convenient. Attached Figure Description

[0035] Reference Figures 1 to 9 This utility model proposes a drainage connector 100.

[0036] In this embodiment of the utility model, the drain connector 100 is applied to a water tank 1 and an overflow pipe 300. The water tank 1 forms a water storage tank 200a. The drain connector 100 includes: a body (not shown), installed in the water tank 1, and forming a drain channel 11a communicating with the water storage tank 200a, the drain channel 11a penetrating the bottom wall of the water storage tank 200a; and a stop structure (not shown), including at least one lever 21, a connecting seat 22, and a plug 23, the connecting seat 22 being connected to the overflow pipe 300. The body has a drain hole 22a that connects to the drain channel 11a. The plug 23 can be partially inserted into the drain hole 22a to separate the drain hole 22a from the drain channel 11a. The actuating rod 21 is connected to the connecting seat 22 and the plug 23. The overflow pipe 300 can be inserted into the drain channel 11a and abut against the actuating rod 21 so that the actuating rod 21 drives the plug 23 to move upward, connecting the drain hole 22a and the drain channel 11a.

[0037] Specifically, in this embodiment, the drain connector 100 can be used in conjunction with the overflow pipe 300 to discharge water from the water tank 1. The water tank 1 includes a tank body 200, which can be a shell structure made of materials such as plastic, glass, or metal, forming a water storage tank 200a for storing water and a through hole 200b communicating with the water storage tank 200a. The through hole 200b is located at the bottom of the tank body 200. The shape of the tank body 200 can be set according to actual needs, such as rectangular or cylindrical.

[0038] The main body includes a first connecting sleeve 11, a second connecting sleeve 12, a fixing seat 13, and an adjusting sleeve 14. The first connecting sleeve 11 is inserted into the through hole 200b and partially interposed in the water storage tank 200a. A limiting flange is formed around the end of the first connecting sleeve 11, which fits against the bottom wall of the water storage tank 200a to secure the first connecting sleeve 11 in the through hole 200b. The first connecting sleeve 11 forms a drainage channel 11a communicating with the water storage tank 200a, and its outer side is formed with external threads. The fixing seat 13 is provided with internal threads. By providing both internal and external threads... The fixed base 13 and the first connecting sleeve 11 are threadedly connected. The adjusting sleeve 14 is also detachably connected to the fixed base 13 by threads. At the same time, the adjusting sleeve 14 abuts against the outer side of the second connecting sleeve 12, pressing the second connecting sleeve 12 against the surface of the fixed base 13. The second connecting sleeve 12 has a plug hole 12a that communicates with the drainage channel 11a. The plug hole 12a allows an external pipe to be plugged in to discharge water from the water storage tank 200a to the outside through the pipe. By rotating the adjusting sleeve 14, the external pipe can be continuously tightened into the plug hole 12a or released from the plug hole 12a. Thus, the overall structure of the main body of this application is simple and easy to disassemble and assemble.

[0039] The main body also includes a sealing gasket 15 and a sealing ring 16. The sealing gasket 15 and sealing ring 16 are made of silicone or rubber. The sealing gasket 15 is circular and can be glued to the side of the fixing seat 13 facing the housing 200. After the fixing seat 13 and the first connecting sleeve 11 are threadedly connected and fixed, the sealing gasket 15 elastically abuts against the lower surface of the fixing seat 13 and the housing 200, preventing water in the water storage tank 200a from flowing out through the gap between them. The fixing seat 13 has an annular groove formed on the side away from the housing 200. The sealing ring 16 is embedded in this groove and elastically abuts against the second connecting sleeve 12, thus preventing water from flowing out through the gap between the fixing seat 13 and the second connecting sleeve 12, improving the waterproof performance of the drain connector 100.

[0040] In this application, under the action of its own gravity and the water pressure in the water tank 1, the plug 23 is firmly inserted into the drain hole 22a, preventing the water in the water storage tank 200a from flowing out and keeping the water level at a certain level. When drainage is required and the water level is lowered, an overflow pipe 300 of a certain length can be inserted from the water storage tank 200a into the drain channel 11a. The wall of the overflow pipe 300 abuts against the pull rod 21, which can drive the plug 23 to move upward against its own force and the water pressure, thereby connecting the drain hole 22a and the drain channel 11a, so that the water in the water storage tank 200a flows out through the drain channel 11a and the drain hole 22a. The drain connector 100 of this application serves two purposes: firstly, it effectively seals the water storage tank 200a, eliminating the need for an additional water valve; secondly, during drainage, simply inserting the overflow pipe 300 into the drain channel 11a eliminates the need for constant monitoring of the water level, as the length of the overflow pipe 300 corresponds to the water level height, allowing for precise water level control. Furthermore, drainage and water shut-off are achieved simply by inserting and removing the overflow pipe 300, making operation simple and convenient.

[0041] Please see again Figure 3In this embodiment, the actuating rod 21 includes a rod body 211 connected to each other and a stop section 212 and a connecting section 213 connected to opposite sides of the rod body 211. The rod body 211, the stop section 212, and the connecting section 213 can be integrally formed by machining or injection molding. Connecting protrusions 2111 are provided on opposite sides of the rod body 211, and a connecting shaft hole 22b is provided on the surface of the connecting seat 22. The connecting protrusions 2111 are fitted into the connecting shaft hole 22b, so that the rod body 211 is rotatably connected to the connecting seat 22. The stop section 212 and the connecting section 213 are set at an included angle, which is an obtuse angle. The plug 23 is provided with a connecting oblong hole 23a, which extends along the width direction of the plug 23. The end of the connecting section 213 away from the rod 211 has a recessed connecting hole 213a. The connector 24 passes through the connecting oblong hole 23a and the connecting hole 213a, connecting the plug 23 and the connecting section 213. It is understood that the connector 24 can be a screw or a pin, and correspondingly, the connecting hole 213a is a screw hole or a pin hole. The diameter of the connecting oblong hole 23a is slightly larger than the diameter of the connecting hole 213a and the diameter of the connector 24 to prevent the connector 24 from getting stuck in the connecting oblong hole 23a.

[0042] Please refer to the above. Figure 8 and Figure 9 In this state, the overflow pipe 300 is not inserted into the drainage channel 11a, that is, in the normal state, the plug 23 is firmly inserted into the drainage hole 22a; during drainage, see Figure 5 and Figure 6 At this time, the overflow pipe 300 is inserted into the drainage channel 11a from the water storage tank 200a, with its pipe wall abutting against the top section 212. The top section 212 moves downward, causing the connecting section 213 to rotate upward around the rod body 211, which in turn causes the plug 23 to move upward against its own force and the water pressure, connecting the drainage hole 22a and the drainage channel 11a, allowing the water in the water storage tank 200a to flow outward through the drainage channel 11a and the drainage hole 22a. After drainage is completed, the overflow pipe 300 is pulled out, and the plug 23 re-seals the drainage hole 22a. The pull rod 21 of this application has a simple structure and is compatible with the plug 23, which can effectively open or seal the drainage hole 22a, making it easier to control the water level in the water storage tank 200a.

[0043] Please see again Figure 3In this embodiment, the stop structure includes two levers 21, which are connected to the surface of the connecting seat 22 and located on opposite sides of the plug 23. The two levers 21 are symmetrically arranged around the central axis of the plug 23. When the overflow pipe 300 is inserted into the drainage channel 11a, it can simultaneously abut against the abutting section 212 of the lever 21. This makes the force on the plug 23 more balanced, and the movement of connecting the drainage channel 11a and the drainage hole 22a upwards or isolating the drainage channel 11a and the drainage hole 22a downwards is smoother.

[0044] Furthermore, the lever 21 also includes a torsion spring (not shown), which is elastically connected to the lever body 211 and the connecting seat 22. The torsion spring can provide elastic force, so that the plug 23 is inserted into the drain hole 22a. That is, the force of the plug 23 sealing the drain hole 22a comes not only from its own weight and water pressure, but also from the elastic force of the torsion spring. Thus, the force of the plug 23 sealing the drain hole 22a is greater, and the sealing performance of the drain connector 100 is better.

[0045] It should be noted that in this application, the diameter of the drainage channel 11a should be slightly smaller than the diameter of the overflow pipe 300, that is, the overflow pipe 300 and the first connecting sleeve 11 are tightly fitted. In this way, after the overflow pipe 300 is inserted into the drainage channel 11a, it can be prevented that the overflow pipe 300 will be displaced upward by the force of the top section 212, and the plug 23 will be re-inserted into the drainage hole 22a, thus affecting the drainage effect.

[0046] Please see again Figure 6 The sealing structure of this application also includes a water-proof ring 25, which is made of elastic silicone or rubber material. The water-proof ring 25 is arranged around the side wall of the drain hole 22a. When the plug 23 is inserted into the drain hole 22a, the water-proof ring 25 and the plug 23 elastically abut against each other. By setting this water-proof ring 25, the sealing performance of the sealing structure can be further improved, preventing water from flowing out under normal water storage conditions.

[0047] Please see again Figure 6 and Figure 9 In this embodiment, the outer side of the connecting seat 22 is provided with an external thread (not shown in the figure), and the inner wall of the drainage channel 11a is provided with an internal thread. That is, the connecting seat 22 and the first connecting sleeve 11 are threadedly connected. Thus, the connection structure of the connecting seat 22 is not only more stable, but also easier to disassemble and assemble.

[0048] This utility model also proposes a water tank 1, which includes a tank body 200, an overflow pipe 300, and a drain connector 100. The specific structure of the drain connector 100 is as described in the above embodiments. Since this water tank 1 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0049] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
