Description

Technical Field

[0001] This utility model relates to the field of sewer pipes, and in particular to a novel multifunctional sewer pipe structure. Background Technology

[0002] There are many scenarios for daily water use. Drainage systems need to be installed in places such as kitchens, bathrooms, and balconies. With the increase in various household appliances, such as fish tanks and water features in the living room, multi-basin sinks in the kitchen, sinks in the washroom, water dispensers, mop sinks, floor drains on balconies, washing machines, and shower rooms in bathrooms, all require drainage pipes. The choice of drainage pipes is a key factor in whether each family can have a smooth water experience.

[0003] With the increasing number of drainage pipes, users will inevitably need drainage pipe systems that are smaller in size, more compact in structure, and more comprehensive in function. The smaller the space occupied by the drainage pipes, the more functions the sewer can perform, freeing up more functional space. Currently, drainage pipe structures that integrate more drainage functions generally occupy a relatively large space. For example, the utility model patent document with patent number CN222252360 U, entitled "Anti-backflow drainage pipe structure," discloses a multi-functional drainage pipe structure that prevents backflow by setting check valves in each water supply pipe. However, check valves need to be set in the horizontal section of the entire structure, which makes the entire drainage pipe structure occupy a lot of horizontal space and is not suitable for installation in confined spaces.

[0004] Therefore, the main problem to be solved by this utility model is to design a drainage pipe structure that occupies little space, achieves multiple functions, and meets various application scenarios. Utility Model Content

[0005] The main purpose of this utility model is to provide a new type of multifunctional drainage pipe structure, which aims to achieve a drainage pipe structure that occupies little space, achieves multiple functions, and meets various application scenarios.

[0006] This utility model proposes a novel multifunctional drainage pipe structure, including a multi-port pipe with a vertical water supply pipe and a lateral water supply pipe. A check valve is installed inside the multi-port pipe, located below the vertical and lateral water supply pipes. The check valve includes a valve body with openings at both ends and an end cap hinged to the valve body. The end cap is horizontally arranged, and the valve body is connected to the multi-port pipe, with the end cap covering the openings of the valve body.

[0007] Preferably, the device further includes an isolator and a flow guide. The isolator is disposed at the end of the outlet of the multi-port pipe. The outer edge of the isolator is configured as a downwardly extending platform-shaped isolation area. The flow guide is connected to the center of the isolation area. The isolation area is provided with an isolation hole for water permeability. The isolation hole isolates solid substances and allows water to pass through. The outer wall of the flow guide has a water passage hole. During installation and use, the isolator is fastened around the port of the external drain pipe, and the flow guide extends into the interior of the external drain pipe. The water passage hole can collect the water flowing in from the isolation hole into the flow guide and flow into the external drain pipe through the flow guide.

[0008] Preferably, the flow guide further includes a secondary check valve, which is disposed at the water outlet end of the flow guide. The secondary check valve is closed when there is no water flow, which can prevent water from flowing back into the external drain pipe and prevent odor from entering the multi-way pipe from the external drain pipe.

[0009] Preferably, the flow guide further includes a sealing ring, which is arranged around the outer wall of the flow guide. During use, the sealing ring abuts against the inner wall of the external drain pipe to prevent water from flowing between the flow guide and the external drain pipe, and at the same time prevents odors from entering from the external drain pipe.

[0010] Preferably, the vertical water supply pipe is provided with a tee or multi-way connector, the outlet port of the tee or multi-way connector is connected to the inlet port of the vertical water supply pipe, and another tee or multi-way inlet port of the tee or multi-way connector is used to connect more drain pipes.

[0011] Preferably, the multi-port pipe has threads on its inner side, the check valve has matching threads on its outer wall, and the check valve is spirally connected to the inside of the multi-port pipe.

[0012] Preferably, the multi-port pipe has a vertical slot at its end, and the isolator has a plug-in part, which is inserted into the slot to complete the connection between the isolator and the multi-port pipe.

[0013] Preferably, the first bottle opener is provided with a connecting hole, and the second bottle opener is provided with a matching connecting block. The connecting block is inserted into the connecting hole to complete the connection between the first bottle opener and the second bottle opener.

[0014] Preferably, a connecting ring is provided at the center of the isolation zone, and a thread is provided inside the connecting ring. The outer wall of the water inlet end of the guide is provided with the device's thread, and the isolation zone is threadedly connected to the guide.

[0015] Preferably, the end of the lateral water supply pipe is provided with a connecting part, the outer edge of the connecting part is provided with an abutment part, the inner wall of the connecting part is provided with a stop ring, the connecting part is inserted into the end of the lateral water supply pipe, the abutment part abuts against the outer wall of the lateral water supply pipe, and the stop ring is used to abut against the end of the external water supply pipe when the external water supply pipe is inserted.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model proposes a novel multi-functional drainage pipe structure, comprising a multi-port pipe, a vertical water supply pipe, a lateral water supply pipe, and a tee or multi-port connector. It also includes an internal check valve and an isolation component with an isolation zone and a flow guide. The flow guide is equipped with a secondary check valve. The vertical and lateral water supply pipes can be connected to various drainage facilities according to usage requirements, accommodating multiple models and types of drainage pipes. The tee or multi-port connector can simultaneously accommodate multiple vertical drainage facilities. The check valve is located inside the multi-port pipe, preventing the vertical structure from growing due to its location at the pipe end and the lateral water supply pipe from growing due to its location inside the lateral water supply pipe. This reduces the footprint of the multi-functional drainage pipe structure. Furthermore, the vertical and lateral water supply pipes are set at an acute angle in the water inlet direction, greatly reducing the space occupied by the pipe and making it suitable for narrower and lower usage scenarios.

[0018] The isolation zone of the isolation component can effectively isolate solid matter in sewage on the floor of rooms with water, such as bathrooms. It is suitable for various usage scenarios with requirements such as floor drainage. The guide component can extend into the interior of external drainage pipes, taking up less space and making it more adaptable. Attached Figure Description

[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, which will be discussed in conjunction with the drawings below. Figure 1-5 The technical solutions in the embodiments of this application will be clearly and completely described.

[0028] This utility model embodiment provides a novel multifunctional drainage pipe structure, including a multi-port pipe 1. The multi-port pipe is equipped with a vertical water supply pipe 2, a lateral water supply pipe 3, and a check valve 4. The vertical water supply pipe 2 and the lateral water supply pipe 3 are connected at an acute angle in the direction of water inflow, which can effectively prevent sewage from flowing between the vertical water supply pipe 2 and the lateral water supply pipe 3. The check valve 4 is located inside the multi-port pipe 1, below the vertical water supply pipe 2 and the lateral water supply pipe 3. The check valve 4 includes a valve body 41 with openings at both ends and an end cap 42 hinged to the valve body. The outer side of the check valve inlet port is threaded, connecting to the internal structure of the multi-port pipe 1. With threaded compatibility, the check valve is screwed into the multi-port pipe 1. The end cap 42 is horizontally arranged and is in a horizontal state under the action of gravity, thereby sealing the outlet port of the valve body 41. In this way, the check valve 4 can prevent water from the external drain pipe from flowing back into the vertical water supply pipe 2 and the side water supply pipe 3, and can also effectively prevent the odor from the external drain pipe from entering the vertical water supply pipe 2 and the side water supply pipe 3. The check valve 4 is set inside the multi-port pipe 1. Compared with the water outlet connected to the multi-port pipe, it does not require additional connection space and the space of the check valve itself, making the structure more compact, small in size and occupying less space.

[0029] To accommodate more rooms with water, surface water needs to be drained. An isolator 5 and a guide 6 are installed at the end of the outlet of the multi-way pipe 1. The outlet port of the multi-way pipe 1 is provided with a slot 11. The inlet port of the isolator 5 is provided with an isolation area 51 extending downward and a plug part 52 extending downward from the outer edge of the isolator 5. When used together, the plug part 52 is inserted into the slot 11. The isolation area 51 surrounds the external outlet. The guide 6 extends into the interior of the external outlet. A connecting ring 511 is provided at the center of the isolation area 51. The inner wall of the connecting ring 511 is provided with threads. The outer wall of the inlet end of the guide 6 is provided with matching threads. The guide 6 and the isolation area 51 are connected by threads.

[0030] An isolation hole 512 for water permeability is provided on the isolation zone 51. The isolation hole 512 allows surface water to flow into the external drainage pipe while preventing solid substances in the surface water from flowing into the external drainage pipe. A water passage hole 61 is provided on the guide member 6. After the surface water flows through the isolation hole 512, it flows into the guide member 6 through the water passage hole 61 and then into the external water outlet.

[0031] In this embodiment, the isolation hole 512 is set as an equidistant sawtooth groove. In other embodiments, the isolation hole 512 can be set as other types that can be used to prevent solid objects from flowing into the external sewer pipe.

[0032] To better seal and prevent sewage backflow, a secondary check valve 62 is installed at the outlet end of the guide member 6, and a sealing ring 63 is installed on the outer wall of the guide member 6. The secondary check valve 62 has the same structure as the check valve 4, which can effectively prevent sewage backflow from the external drain and effectively prevent odor from the external drain from rising. When in use, the sealing ring 63 abuts against the inner wall of the external drain, which again blocks sewage backflow from the external drain and effectively prevents odor from the external drain from rising.

[0033] To expand the multi-functional connection of the vertical water supply pipe 2, a tee or multi-way connector 7 is provided on the vertical water supply pipe 2. The outlet port of the tee or multi-way connector 7 is connected to the inlet port of the vertical water supply pipe, and the other tee or multi-way inlet port of the tee or multi-way connector is used to connect more drainage pipes, thereby realizing the connection of various vertical drainage devices.

[0034] The lateral water supply pipes 3 are configured with different pipe diameters. The end of the larger diameter lateral water supply pipe 3 is provided with a connecting part 8 for better connection to external large-diameter drainage pipes. The outer edge of the connecting ring 8 is provided with a resisting part 81, and the inner wall of the connecting ring 8 is provided with a stop ring 82. The connecting part 8 is inserted into the end of the lateral water supply pipe 3, and the abutting part 81 abuts against the outer wall of the lateral water supply pipe 3. The stop ring 82 is used to abut against the end of the external water supply pipe when it is inserted, preventing the external water supply pipe from entering further. Depending on the diameter, the lateral water supply pipe 3 can be used to connect to the drainage pipe of equipment, or it can be used as an overflow pipe or to connect to small drainage pipes such as household water purifiers. The different diameters of the lateral drainage pipes 3 can meet the access of drainage pipes with multiple functions.

[0035] In another embodiment, a novel multifunctional drainage pipe structure is provided, primarily for installation in kitchens. The vertical water supply pipe 2 is directly connected to the vertical drainage pipe of the kitchen. The side water supply pipes 3 are configured with different diameters, with the smaller diameter connecting the water purifier and the overflow pipe for wastewater discharge from the kitchen water purifier and overflow from the sink. The check valve 4 is installed at the lower end of all the side water supply pipes 3 and inside the vertical water supply pipe. The outlet end of the vertical water supply pipe 2 is directly connected to the water supply pipe. The check valve 4 is installed inside the vertical water supply pipe 2, which can minimize the overall length of the drainage pipe structure, making it more suitable for kitchens with limited vertical installation space and freeing up more effective functional space in the kitchen.

[0036] Another embodiment provides a novel multi-functional drainage pipe structure mainly used in scenarios requiring the connection of multiple different drain outlets. A T-connector 7 is connected to the upper end of the vertical water supply pipe 2. The T-connector 7 can be connected to vertical drain pipes in the scenario and then merge into the vertical water supply pipe 2. This allows a single multi-functional drainage pipe structure to efficiently solve scenarios requiring multiple vertical drain outlets. In this embodiment, the T-connector 7 is connected to the vertical water supply pipe 2 via a plug-in connection. In other embodiments, other connection methods such as spiral connections can also be used. Simultaneously, the lateral water supply pipes 3 are configured with different diameters, allowing for… Different drain pipes are connected according to different drainage volumes, so that the multi-functional drainage pipe structure can meet various drainage needs. The check valve 4 is installed at the lower end of all lateral water supply pipes 3 and inside the vertical water supply pipe. The outlet end of the vertical water supply pipe 2 is directly connected to the water supply pipe. The check valve 4 is installed inside the vertical water supply pipe 2, which can minimize the length of the overall drainage pipe structure to adapt to more scenario needs. The tee connector 7 and the various pipe diameters of the vertical water pipe 3 can better adapt to various and different drain outlets. Moreover, a single multi-functional drainage pipe structure can solve all drainage problems in functional rooms, which is simple and efficient.
