Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pipe joint technology, specifically relating to a multifunctional drainage pipe joint. Background Technology
[0002] Most drain pipe fittings on the market today use a single-interface design, which can only accommodate the connection needs of a single drainage device (such as a sink, dishwasher, or washing machine). In practical applications, when users need to connect multiple devices simultaneously (for example, integrating a sink, water purifier, and dishwasher in a kitchen environment), it is usually necessary to install multi-way adapters such as tees and crosses. This leads to increased complexity in the piping system, a greater number of interfaces, and a significantly higher risk of seal failure. Furthermore, the stacking of multi-way fittings greatly increases the risk of leaks and occupies too much space, making it difficult to meet the installation requirements of compact drainage pipes.
[0003] On the other hand, existing drain pipe joints cannot achieve bidirectional compatibility between floor drain pipes and wall drain pipes. Specifically, when connecting floor drain pipes, the drain outlet of the joint must be installed vertically, while connecting wall drain pipes requires an inclined or horizontal installation direction. The poor compatibility between the two installation methods leads to an imbalance in the connection angle between the sink drain pipe and the joint, which in turn causes problems such as pipe twisting and deformation, reduced drainage flow rate, and blockage due to dirt accumulation. Summary of the Invention
[0004] This utility model addresses the aforementioned problems in the existing technology by proposing a multifunctional drainage pipe connector that can be simultaneously adapted to ground drainage pipes and wall drainage pipes, and can be connected to multiple devices.
[0005] This utility model can be achieved through the following technical solutions:
[0006] A multi-functional drain pipe connector, comprising:
[0007] The connector body has an inner cavity that is a drainage cavity. The top of the connector body is provided with multiple connecting joints, and the cavity of each connecting joint is respectively connected to the drainage cavity. The bottom of the connector body is provided with a drain outlet, which is connected to the drainage cavity.
[0008] The connecting joint includes an inclined water tank connector, the inclination direction of which is configured as follows:
[0009] When the drain outlet is connected to the ground drain pipe, the connector body is installed vertically, and at this time, an acute angle is formed between the water tank connector and the vertical surface;
[0010] When the drain outlet is connected to the wall drain pipe, the main body of the connector is installed at an angle or horizontally, at which time an acute angle is formed between the sink connector and the vertical surface.
[0011] As a further improvement of this utility model, the included angle between the axis of the water tank connector and the axis of the connector body is 40°-50°.
[0012] As a further improvement of this utility model, the connecting connector also includes at least one of a dishwasher connector, a water purifier connector, and a rubber hose connector.
[0013] As a further improvement of this utility model, the axial directions of the dishwasher connector, the water purifier connector, and the rubber hose connector are all parallel to the axial direction of the connector body.
[0014] As a further improvement of this utility model, the water tank connector is provided with a water tank odor prevention core, and the sewage in the water tank flows into the drainage cavity after passing through the water tank odor prevention core.
[0015] As a further improvement of this utility model, a total odor-proof core is provided inside the drain outlet, and the sewage in the drain chamber is discharged outward after passing through the total odor-proof core.
[0016] As a further improvement of this utility model, the odor-proof core of the water tank and the total odor-proof core are configured as magnetic odor-proof cores.
[0017] As a further improvement of this utility model, the bottom opening of the magnetic anti-odor core is provided with a magnetic suction plate, which is configured to open the bottom opening by water flow impact and close the bottom opening by magnetic attraction.
[0018] As a further improvement of this utility model, the bottom opening of the magnetic odor-proof core is inclined, and the magnetic plate is hinged to the short side of the magnetic odor-proof core to form a flip-top structure.
[0019] As a further improvement of this utility model, the bottom opening of the magnetic deodorizing core is provided with an arc-shaped guide surface.
[0020] Compared with the prior art, the present invention has the following beneficial effects:
[0021] 1. Improved compatibility with multiple devices: By integrating multiple connectors, multiple devices can be directly connected without the need for additional adapters, simplifying the piping system structure and reducing the risk of leakage.
[0022] 2. Improved versatility: The inclined sink connector design ensures that the sink drain pipe can be smoothly connected at a natural angle whether the connector is installed vertically or at an incline, avoiding pipe twisting, improving drainage efficiency, and preventing the accumulation of dirt.
[0023] 3. The sink connector is equipped with a sink anti-odor core, and the drain outlet is equipped with a main anti-odor core. This double anti-odor design can not only effectively prevent backflow and odor from the floor or wall drain pipes, but also provides extra protection for the sink connector, preventing sewage and odor from entering the drain chamber from the sink connector when other devices (such as dishwashers, water purifiers, etc.) are in use. Attached Figure Description
[0024] Figure 1 This is a structural schematic diagram of the multifunctional drain pipe connector of this utility model;
[0025] Figure 2 This is a cross-sectional view of the multifunctional drain pipe connector of this utility model.
[0026] In the diagram, 100 is the connector body; 110 is the drain chamber; 120 is the drain outlet; 130 is the sink connector; 140 is the dishwasher connector; 150 is the water purifier connector; 160 is the rubber hose connector; 170 is the sink odor-proof core; 180 is the main odor-proof core; 181 is the magnetic suction plate; and 182 is the arc-shaped guide surface. Detailed Implementation
[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. The technical methods of the present invention will be further described, but the present invention is not limited to these embodiments.
[0028] like Figures 1-2 As shown, this utility model provides a multifunctional drain pipe connector, comprising:
[0029] The connector body 100 has an inner cavity that is a drain cavity 110. The top of the connector body 100 is provided with multiple connecting connectors, and the cavity of each connecting connector is connected to the drain cavity 110. The bottom of the connector body 100 is provided with a drain outlet 120, which is connected to the drain cavity 110. By integrating multiple connecting connectors on the connector body 100, the connector can be connected to multiple devices such as sinks, dishwashers, and water purifiers at the same time without the need for additional T-junctions or cross-junctions.
[0030] The connecting joint includes an inclined water tank connector 130, the inclination direction of which is configured as follows:
[0031] When the drain outlet 120 is connected to the ground drain pipe, the connector body 100 is installed vertically, and at this time, the sink connector 130 and the vertical surface form an acute angle.
[0032] When the drain outlet 120 is connected to the wall drain pipe, the connector body 100 can be installed at an angle or horizontally, and the sink connector 130 still maintains an acute angle with the vertical plane.
[0033] In other words, regardless of whether the connector body 100 is installed vertically (to fit ground drainage pipes) or tilted / horizontally (to fit wall drainage pipes), the sink connector 130 always forms a reasonable angle with the vertical direction, thereby ensuring that the sink drainage pipe will not be bent at a large angle when connected, but will be connected in a smooth transition manner, avoiding problems such as pipe twisting and deformation, reduced drainage flow rate, and dirt accumulation and blockage caused by mismatched angles.
[0034] Overall, the multifunctional drain pipe connector provided in this embodiment has at least the following advantages:
[0035] 1. Improved compatibility with multiple devices: By integrating multiple connectors, multiple devices can be directly connected without the need for additional adapters, simplifying the piping system structure and reducing the risk of leakage.
[0036] 2. Improved versatility: The 130-degree angled sink connector design ensures that the sink drain pipe can be smoothly connected at a natural angle, whether the connector is installed vertically or at an angle, avoiding pipe twisting, improving drainage efficiency, and preventing the accumulation of dirt.
[0037] Preferably, the angle between the axis of the sink connector 130 and the axis of the connector body 100 is 40°-50°. This design not only ensures that the sink connector 130 can be connected at a reasonable angle under different installation conditions (whether it is a ground drain pipe or a wall drain pipe), but also optimizes the angle of the drainage channel, ensuring that sewage can flow into the drain chamber 110 with minimal resistance. This effectively prevents water flow obstruction and potential blockage caused by sharp turns, and improves drainage efficiency.
[0038] This design not only enhances the adaptability of the connector under different installation conditions, maintaining the optimal connection angle for both floor and wall-mounted drain pipe connections, reducing the risk of pipe stress and deformation, but also simplifies the installation process, improves the user's installation experience, and enhances the overall durability of the system.
[0039] Preferably, the connector also includes at least one of dishwasher connector 140, water purifier connector 150 and rubber hose connector 160. When a connector is not in use, the pipe opening can be blocked with a plug. This design allows a multi-functional drain pipe connector to meet the drainage needs of multiple devices at the same time. For example, sinks, dishwashers and water purifiers in the kitchen environment can be directly connected to this connector for drainage.
[0040] In other words, this integrated design also greatly improves the integration and flexibility of the drainage system, reduces the number and complexity of accessories required during installation, simplifies the pipe layout, saves space, and reduces the potential risk of leakage.
[0041] Preferably, the axial directions of the dishwasher connector 140, water purifier connector 150, and rubber hose connector 160 are all parallel to the axial direction of the connector body 100, ensuring that the layout of each connector is neat and compact. This not only facilitates installation and maintenance but also effectively reduces mutual interference between pipes, making the layout of the entire drainage system more reasonable.
[0042] Preferably, the sink connector 130 is provided with a sink odor-proof core 170, and the sewage in the sink flows into the drain chamber 110 after passing through the sink odor-proof core 170. At the same time, the drain outlet 120 is provided with a total odor-proof core 180, and the sewage in the drain chamber 110 is discharged outward after passing through the total odor-proof core 180.
[0043] This dual odor-proof design not only effectively prevents backflow and odor from the floor or wall drain pipes, but also provides extra protection for the sink connector 130, preventing sewage and odor from entering the drain chamber 110 through the sink connector 130 when other appliances (such as dishwashers, water purifiers, etc.) are in use.
[0044] Overall, this design greatly enhances the safety and reliability of the drainage system while maintaining fresh indoor air, improving hygiene standards and the quality of the living environment.
[0045] In addition, the dual odor-proof design simplifies the maintenance process. In the event of a blockage or backflow, the specific location can be quickly identified and addressed without requiring a comprehensive inspection of the entire system. This improves problem-solving efficiency and enhances the user experience. Overall, this design provides modern families with an efficient, safe, and easy-to-maintain drainage solution.
[0046] Preferably, the sink odor-proof core 170 and the main odor-proof core 180 are configured as magnetic odor-proof cores. Specifically, the bottom opening of the magnetic odor-proof core is provided with a magnetic plate 181. The magnetic plate 181 is configured to open the bottom opening by water flow impact and close the bottom opening by magnetic attraction.
[0047] The magnetic anti-odor core design enables it to automatically open and close without manual intervention, intelligently responding to the drainage status and improving ease of use and sealing reliability. The magnetic plate 181 opens with water flow and resets with magnetic force, making it sensitive and stable. Compared to water-sealed anti-odor cores, it will not lose its anti-odor function due to the drying of the drain over a long period of time, thus making it more stable in use.
[0048] Furthermore, the bottom opening of the magnetic odor-proof core is inclined, and the magnetic plate 181 is hinged to the short side of the magnetic odor-proof core to form a flip-top structure. By adopting the flip-top structure formed by the inclined bottom opening and the hinged magnetic plate 181 to the short side of the odor-proof core, the magnetic odor-proof core can be opened more flexibly under the impact of water flow, and quickly reset to achieve tight closure after drainage, effectively improving the opening and closing sensitivity and sealing performance, and preventing odors and sewage backflow.
[0049] In addition, this design reduces water flow resistance, enhances drainage smoothness, and has strong anti-blocking ability, ensuring stable and reliable operation and facilitating cleaning and maintenance. This further ensures the safe and efficient operation of the drainage system and extends its service life.
[0050] Preferably, the bottom opening of the magnetic odor-proof core is provided with an arc-shaped guide surface 182, which allows sewage to flow into the drainage system more smoothly, effectively reducing water flow resistance and lowering the risk of blockage.
[0051] This design not only further improves drainage efficiency and system stability, but also helps guide debris to pass through smoothly, preventing impurities from accumulating at the opening. At the same time, it reduces the impact on the magnetic plate 181, extends its service life, and ensures the long-term reliable operation and easy maintenance of the drainage system.
