Description

Technical Field

[0001] This utility model belongs to the field of drainage system technology, and specifically relates to an adapter cover for drainage appliances. Background Technology

[0002] Floor drains are the key interface connecting sewer pipes to the indoor floor. They are commonly installed on the floor in spaces such as kitchens, bathrooms, and balconies. As a core component of the drainage system, their performance directly affects indoor air quality, especially playing a crucial role in odor control.

[0003] Chinese patent CN206308789U discloses a magnetically levitated drain core, comprising a cylindrical body, a cylindrical inner shell connected to the cylindrical body, and a sealing element. A bracket is connected to the lower end of the cylindrical body. The sealing element includes a rod and a sealing part. The rod passes through the bracket. A reset mechanism is provided between the sealing element and the bracket, and the sealing element can abut against the lower end of the inner shell and seal under the action of the reset mechanism. The middle part of the sealing part protrudes upward and the upper side of the sealing part forms a drainage surface including a curved surface or several inclined planes. The drainage surface of the sealing part also has several guide grooves extending from the middle of the sealing part to the edge. The sidewall of the guide groove has an inclined or curved guide surface, and the guide surface can be subjected to the force of water flow and cause the sealing element to rotate around the axis of the rod.

[0004] The above technical solution has the following drawbacks: the drain core is only suitable for draining surface water. When the user uses the washing machine, if the drain pipe is directly inserted into the sewer opening, it will occupy the drain opening, preventing other pipes from draining at the same time. If the washing machine drain pipe is placed on the ground, so that the wastewater flows to the ground first and then drains through the drain core, the ground will still be damp after the water is drained, requiring the user to clean it manually, which brings inconvenience to daily use. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing an adapter cover for drainage devices. The technical problem to be solved by this utility model is: how to achieve multi-channel drainage under the premise of a single drainage outlet.

[0006] The above-mentioned technical objective of this utility model can be achieved through the following technical solution: a transition cover for a drainage appliance, comprising a transition cover body, the transition cover body being connected to a drainage adapter, the transition cover body being used to connect the drainage adapter and the drain outlet, the ground and the drain outlet being connected through a drainage channel, and moving the transition cover body can increase or decrease the drainage flow of the drainage channel.

[0007] In the aforementioned adapter cover for a drainage appliance, a drainage component is installed inside the drain outlet, and the lower end of the adapter cover body is located inside the drainage component.

[0008] In the aforementioned adapter cover for a drainage appliance, the drainage component includes a floor drain, and the lower end of the adapter cover body has a connecting part. The connecting part is threaded into the floor drain and is located within the drainage channel. A through hole for water to flow through is provided on the connecting part.

[0009] In the aforementioned adapter cover for a drainage appliance, the drainage component includes a drain pipe, and the lower end of the adapter cover body extends into the drain pipe.

[0010] In the aforementioned adapter cover for a drainage appliance, a sealing ring is provided on the outer wall of the connecting part.

[0011] In the aforementioned adapter cover for a drainage appliance, the adapter cover body has a stepped surface, the floor drain includes a floor drain core, the stepped surface is opposite to the upper surface of the floor drain core, and an opening for water flow is formed between the stepped surface and the upper surface of the floor drain core. When the adapter cover body is rotated, the opening can become larger or smaller, and the opening is located within the drainage channel.

[0012] In the aforementioned adapter cover for a drainage device, the stepped surface has a support portion, and the lower surface of the support portion can abut against the upper surface of the drain core.

[0013] In the aforementioned adapter cover for a drainage appliance, the outer side wall of the adapter cover body has a flange, and the lower surface of the flange has a protrusion. The floor drain also includes a floor drain body. When the adapter cover body is rotated, the distance between the lower surface of the protrusion and the ground or the upper surface of the floor drain body can increase or decrease, and the lower surface of the protrusion can abut against the ground or the upper surface of the floor drain body.

[0014] In the aforementioned adapter cover for a drainage appliance, the drainage adapter has at least two water inlet ports, one of which is fitted with a plug, and the other water inlet port is threaded with a connector for connecting to an external pipe.

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments. Example 1:

[0019] An adapter cover for a drainage device, such as Figures 1 to 4 As shown, it includes an adapter cover body 1, which is connected to a drainage adapter 2. Preferably, the end of the drainage adapter 2 is threadedly connected to the upper end of the adapter cover body 1.

[0020] The drain adapter 2 has at least two water inlet ports 14. One of the water inlet ports 14 is fitted with a plug 15. Preferably, the plug 15 is threaded to the inner wall of the water inlet port 14. Alternatively, the plug 15 can be installed in the water inlet port 14 by plugging and unplugging. As long as the plug 15 is removable, it can be used when the user needs to use the water inlet port 14 for drainage. When not in use, the water inlet port 14 is sealed with the plug 15 to prevent external impurities from entering the water inlet port 14. The other water inlet port 14 is threaded to a connector 16 for connecting to an external pipe. The connector 16 is connected to the water inlet port 14 by a threaded connection, which facilitates the disassembly and maintenance of the connector 16. That is, the user can replace the connector 16 with one that is compatible with the specifications of the external pipe. When the external water-using equipment (washing machine) needs to discharge wastewater, it is only necessary to connect the drain pipe of the external water-using equipment to the connector 16. The connector 16 is preferably a pipe fitting.

[0021] A sealing element is provided on the connector 16. In this embodiment, the sealing element includes a sealing ring 17. The sealing ring 17 is disposed on the outer side wall of the connector 16. The number of sealing rings 17 can be increased or decreased as needed, and there is no specific limitation. It should be noted that the sealing ring 17 seals the connection between the connector 16 and the external pipe, ensuring the sealing performance between the two. Of course, the friction generated between the sealing ring 17 and the external pipe can also further improve the stability of the connection between the connector 16 and the external pipe.

[0022] As an alternative, the sealing element includes a sealing sleeve 18, which is fitted onto the outer wall of the connector 16. It should be noted that the sealing sleeve 18 seals the connection between the connector 16 and the external pipe, ensuring the airtightness between the two. Of course, the friction generated between the sealing sleeve 18 and the external pipe can also further improve the stability of the connection between the connector 16 and the external pipe.

[0023] The adapter cover body 1 is used to connect the drainage adapter 2 and the drain outlet 21. The ground 3 and the drain outlet 21 are connected through the drainage channel 4.

[0024] Specifically, a drainage component is installed inside the drain outlet 21, and the lower end of the adapter body 1 is located inside the drainage component. It should be noted that when the user connects the drain pipe of the external water-using equipment to any one of the water inlet ports 14 on the drain adapter 2, the wastewater generated by the water-using equipment can be discharged from its drain pipe and enter the drain adapter 2, then enter the drainage component through the adapter body 1, and then be discharged outwards. At the same time, wastewater on the ground 3 can also directly enter the drainage component through the drainage channel 4 and then be discharged outwards. This allows for multiple drainage paths under the premise of a single drain outlet 21, which is convenient for users and meets their different usage needs.

[0025] In this embodiment, the drainage component includes a floor drain. The lower end of the adapter body 1 has a connecting part 6, which is annular. The connecting part 6 is threaded into the floor drain and located in the drainage channel 4. The connecting part 6 has a through hole 7 for water to flow through. There is at least one through hole 7. Preferably, there are several through holes 7 and they are evenly distributed along the circumference of the connecting part 6 to ensure the drainage volume of the drainage channel 4 and reduce the impact of the connecting part 6 on the drainage volume of the drainage channel 4.

[0026] Since the connecting part 6 is threadedly engaged with the floor drain, the position of the adapter body 1 relative to the floor drain can be changed by rotating the adapter body 1.

[0027] Furthermore, a sealing ring 8 is provided on the outer wall of the connecting part 6. The friction between the sealing ring 8 and the outer wall of the connecting part 6 and the inner wall of the floor drain ensures the stability of the position of the adapter body 1 relative to the floor drain.

[0028] Preferably, the drain is equipped with an odor-proof core 19, which prevents odors and backflow.

[0029] The outer wall of the floor drain is fitted with a reducing ring 20, which allows the floor drain to be tightly locked inside the drain outlet 21, ensuring the stability of the floor drain after installation.

[0030] The movable adapter body 1 can increase or decrease the drainage flow of the drainage channel 4. In this embodiment, since the connecting part 6 is threaded into the floor drain, the adapter body 1 can be moved relative to the floor drain by rotating it.

[0031] Specifically, the main body 1 of the adapter cover has a stepped surface 9, and the floor drain includes a floor drain core 511. The stepped surface 9 is opposite to the upper surface of the floor drain core 511, and an opening 10 for water flow is formed between the stepped surface 9 and the upper surface of the floor drain core 511. When the main body 1 of the adapter cover is rotated, the opening 10 can become larger or smaller. The opening 10 is located in the drainage channel 4. It should be noted that by rotating the main body 1 of the adapter cover, the main body 1 of the adapter cover is moved relative to the floor drain core 511, thereby changing the distance between the stepped surface 9 and the upper surface of the floor drain core 511, and thus changing the size of the opening 10. Since the opening 10 is located in the drainage channel 4, the drainage volume of the drainage channel 4 can be adjusted by changing the size of the opening 10.

[0032] The step surface 9 has a support part 11. By rotating the main body 1 of the adapter cover, the lower surface of the support part 11 can abut against the upper surface of the drain core 511. The abutting action of the two restricts the position of the main body 1 of the adapter cover relative to the drain core 511. It should be noted that when the lower surface of the support part 11 abuts against the upper surface of the drain core 511, the opening 10 is at its smallest, but the opening 10 is not completely closed at this time, and water can still flow through the opening 10.

[0033] The support portion 11 is preferably a plurality of portions and is evenly distributed along the circumference of the step surface 9. Through the blocking effect of the support portion 11, external impurities and hair can be prevented from passing through the opening 10.

[0034] The outer side wall of the adapter cover body 1 has a flange 12, and the lower surface of the flange 12 has a protrusion 13. When the adapter cover body 1 is rotated, the distance between the lower surface of the protrusion 13 and the ground 3 can be increased or decreased. It should be noted that the vertical distance (depth) between different drain cores 511 and the ground 3 is different. Therefore, by adjusting the distance between the lower surface of the protrusion 13 and the ground 3 through the adapter cover body 1, the installation requirements of different drain cores 511 can be met.

[0035] It should be noted that the protrusions 13 are preferably a plurality of ones and are evenly distributed along the circumference of the flange 12. This ensures stable support of the ground 3 to the main body 1 of the adapter cover, and the protrusions 13 prevent external impurities and hair from passing between the flange 12 and the ground 3.

[0036] Wastewater on the ground 3 passes between the lower surface of the flange 12 and the ground 3, and between the lower surface of the protrusion 13 and the ground 3, then flows into the drain core 511 through the opening 10, and is discharged outward through the through hole 7. This is the drainage channel 4.

[0037] It should be noted that by rotating the main body 1 of the adapter cover, the main body 1 of the adapter cover moves relative to the drain core. As the main body 1 of the adapter cover moves, the position of the flange 12 and the protrusion 13 relative to the main body 1 of the adapter cover changes, and the distance between the lower surface of the flange 12 and the lower surface of the protrusion 13 and the ground 3 changes. The wastewater on the ground 3 passes through the distance between the lower surface of the flange 12 and the ground 3 and the lower surface of the protrusion 13 and the ground 3, and then flows into the drain core through the opening 10, and then is discharged outward through the through hole 7. Therefore, by moving the main body 1 of the adapter cover to change the distance between the lower surface of the flange 12 and the lower surface of the protrusion 13 and the ground 3, the drainage volume of the drainage channel 4 can be adjusted.

[0038] When the vertical distance (depth) between the drain core 511 and the ground 3 is large, the lower surface of the protrusion 13 can abut against the ground 3. Through the abutment between the two, the ground 3 supports the main body 1 of the adapter cover, thereby ensuring the stability of the position of the main body 1 of the adapter cover. At this time, water flows from the lower surface of the flange 12 to the ground 3 (i.e., between two adjacent protrusions 13).

[0039] When the external water-using equipment discharges wastewater, the drain pipe of the external water-using equipment can be connected to any of the inlet interfaces 14. The wastewater enters the drain adapter 2 from the inlet interface 14, then enters the drain core through the adapter cover body 1, and then pushes the odor-proof core 19 to be discharged outward. The wastewater on the ground 3 passes between the lower surface of the flange 12 and the lower surface of the protrusion 13 and the ground 3, then flows into the drain core 511 through the opening 10, and then is discharged outward through the through hole 7. Example 2:

[0040] The difference between Example 2 and Example 1 is that, as Figures 5-6 As shown, the floor drain also includes a floor drain body 512, which is sleeved on the outside of the floor drain core 511. The floor drain body 512 is installed on the ground 3. When the adapter cover body 1 is rotated, the adapter cover body 1 moves, and the distance between the lower surface of the protrusion 13 and the upper surface of the floor drain body 512 can be increased or decreased.

[0041] By rotating the adapter cover body 1 to move it relative to the drain body 512, the distance between the lower surface of the flange 12 and the lower surface of the protrusion 13 and the upper surface of the drain body 512 is changed. Wastewater on the ground 3 passes between the lower surface of the flange 12 and the upper surface of the drain body 512, and between the lower surface of the protrusion 13 and the upper surface of the drain body 512, and then flows into the drain core through the opening 10, and then is discharged outward through the through hole 7. Therefore, by moving the adapter cover body 1 to change the distance between the lower surface of the flange 12 and the lower surface of the protrusion 13 and the upper surface of the drain body 512, the drainage volume of the drainage channel 4 can be adjusted.

[0042] The lower surface of the protrusion 13 can abut against the upper surface of the drain body 512. Through the abutment of the two, the adapter body 1 is supported, thereby ensuring the stability of the position of the adapter body 1. By changing the distance between the lower surface of the protrusion 13 and the upper surface of the drain body 512, different sizes of drain bodies 512 can be adapted, which can effectively improve versatility and practicality. Example 3:

[0043] The difference between Example 3 and Example 1 is that, as Figures 7-8 As shown, the drainage component includes a drain pipe 52, which is installed inside the drain outlet 21. The lower end of the adapter body 1 extends into the drain pipe 52. At this time, the lower surface of the protrusion 13 abuts against the ground 3, thereby supporting the adapter body 1 through the ground 3, thus ensuring the stability of the position of the adapter body 1. The step surface 9 and the upper surface of the drain pipe 52 form the opening 10 through which the water supply flows.

[0044] like Figure 6As shown, when the external water-using equipment discharges wastewater, the drain pipe of the external water-using equipment can be connected to any one of the inlet ports 14. The wastewater enters the drain adapter 2 from the inlet port 14, and then enters the drain pipe 52 through the adapter cover body 1 and is discharged outward. The wastewater on the ground 3 passes between the lower surface of the flange 12 and the ground 3 (i.e., the interval between two adjacent protrusions 13), and then flows into the drain pipe 52 through the opening 10, and then passes through the through hole 7 and is discharged outward.
