[0017] This disclosure provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The particular embodiments are merely illustrative of specific configurations and do not limit the scope of the claimed embodiments. Features from different embodiments may be combined to form further embodiments unless noted otherwise. Various embodiments are illustrated in the accompanying drawing figures, where identical components and elements are identified by the same reference number, and repetitive descriptions are omitted for brevity.
[0018] Variations or modifications described in one of the embodiments may also apply to others. Further, various changes, substitutions, and alterations can be made herein without departing from the spirit and scope of this disclosure as defined by the appended claims.
[0019] While the aspects are described primarily in the context of residential bathroom and kitchen drains, it should also be appreciated that these aspects may also apply to other drainage systems. In particular, aspects of this disclosure may apply to commercial washbasins, industrial cleaning stations, utility sinks, bathtubs, showers, spas, swimming pools, recreational vehicles, boats, and other plumbing fixtures utilizing drain openings. Further, although standard drain openings are referenced throughout, the disclosed embodiments may be adapted for customsized or non-standard drain openings with appropriate dimensional modifications while maintaining the same operational principles and benefits.
[0020] In embodiments, a drain stopper with a plunging seal is proposed as an integrated solution for closing a drain and clearing clogs without requiring separate tools or chemical cleaners. In embodiments, the disclosed drain stopper fits standard residential and commercial drain openings while maintaining the conventional function of a typical drain stopper. The design incorporates a folding, expandable sealing element that increases the internal volume compared to standard drain seals, thereby generating greater suction and pressure when operated to clear obstructions.EDC-OO1 -4-
[0021] Users can operate the drain stopper by opening and closing it according to the specific configuration, such as pop-up, lift-and-turn, or twist-lock mechanisms. When closed, the stopper forces water and air downward through the drainpipe, helping to dislodge debris. When opened, the flexible sealing element creates suction that draws obstructions upward. This open-and-close sequence may be repeated as necessary to eliminate blockages.
[0022] The drain stopper with plunging seal offers several advantages over conventional solutions. Unlike external plungers that require separate storage, frequent cleaning, and manual effort, the integrated design remains in place and ready for use. The solution avoids the drawbacks of chemical drain cleaners, which can be corrosive to pipes, environmentally harmful, and ineffective against solid obstructions. The drain stopper does not require modifications to existing plumbing systems, making it practical for standard drain setups.
[0023] Various embodiments of the drain stopper may include different actuation mechanisms, such as spring-powered operation, lever controls, or motorized versions. The expandable sealing element can be offered in different shapes and materials to accommodate various drain geometries. Some versions may incorporate features like one-way valves to prevent backflow, built-in indicators to provide feedback on water flow or clog severity, or smart capabilities to detect forming clogs and automatically perform plunging actions.
[0024] The drain stopper with plunging seal can be implemented in numerous applications beyond residential settings, including commercial facilities, industrial environments, recreational vehicles, and boats. The universal compatibility and operation make it suitable for widespread adoption across diverse drainage applications. These and additional details are further discussed below.
[0025] Figure 1 illustrates a perspective view of a drain stopper 100 in a fully open position, according to an embodiment of the disclosure. The drain stopper 100 includes a cap 102, a plunging seal 104, and a central shaft 106, which maybe arranged as shown. Drain stopper 100 may include additional components not shown.EDC-OO1 -5-
[0026] In embodiments, drain stopper 100 is a drain closure body configured to fit standard residential and commercial drain openings, preserving the typical function of a conventional drain stopper. The body can be sized to accommodate an integrated plunging function, eliminating the need for additional plumbing modifications. The drain stopper 100 combines drain closure and clog-clearing capabilities in a single integrated unit.
[0027] The cap 102 is positioned at the top of the assembly. The cap 102 may be formed from a durable, water-resistant material such as plastic, metal, ceramic, or composite materials. It has a generally circular, dome-shaped profile with a smooth upper surface extending outward beyond the diameter of the plunging seal 104. The cap 102 may include a knob to twist or plunge the stopper into the closed or open positions. In some embodiments, the cap 102 can be part of a push-and-pull stopper, which is closed when pushed down and open when pulled up. The cap 102 may also include textured portions or grip elements on its upper surface to facilitate manual operation.
[0028] Below the cap 102 is a plunging seal 104, which can have an accordion-like structure with concentric folds that can expand and contract during operation. The plunging seal 104 is shown in its expanded state in the open position. Disposed within the stopper body, the sealing element is folding and expandable, providing increased internal volume relative to a standard drain seal.
[0029] When the drain stopper 100 is opened and closed, the expandable sealing element deforms to generate the suction and pressure necessary for clearing obstructions. The plunging seal 104 maybe constructed from a flexible, resilient material such as rubber, silicone, or other elastomeric compounds that provide durability and water-tight sealing capabilities. The accordion folds may be uniformly spaced and sized to allow for consistent expansion and contraction during the plunging action.
[0030] The central shaft 106 is coupled to the cap 102 and extends along the interior portion of the plunging seal 104. It then extends downward from the cap 102 through the plunging sealEDC-OO1 -6-104 into the drain. To provide structural support for the assembly, the central shaft 106 may be constructed from rigid materials such as metal, hard plastic, or composite materials. It may have a cylindrical shape with a diameter proportioned to allow adequate water flow around it while maintaining structural integrity.
[0031] Water flow 108 is indicated by directional arrows on the sides of the assembly, showing the unobstructed passage of water through the drain opening. The arrows illustrate how water can flow freely around the expanded plunging seal 104 when the drain stopper 100 is open.
[0032] As shown, the assembly is installed in a tub / basin 110, depicted on the sides of the drain stopper 100. The tub / basin 110 represents the fixture in which the drain stopper too is installed, which may be a sink, bathtub, shower, or other plumbing fixture with a standard drain opening. The tub / basin no may be made of various materials, including porcelain, ceramic, metal, fiberglass, or composite materials.
[0033] In this open configuration, the drain stopper too allows water to freely flow from the tub / basin 110 through the drain opening. The expanded state of the plunging seal 104 provides sufficient clearance for water to pass through the drain without obstruction, while maintaining the capability to contract and create a seal when moved to the closed position.
[0034] In embodiments, the body of the drain stopper 100 can include a mechanical feature (not shown) to attach to the drain of the tub / basin 110. For example, the mechanical feature can can be a screw under the cap 102 or other fastening mechanisms that secure the drain stopper too in place. The drain stopper 100 can be implemented in various configurations, such as a push-and-pull stopper, a lift-and-turn stopper, a toe-touch stopper, or a pop-up stopper, depending on user preferences and specific applications.
[0035] The drain stopper 100 may be removable to facilitate cleaning or replacement of components. In some embodiments, the mechanism that opens and closes the drain via the stopper can be through a lever mechanically coupled to the stopper. This lever maybeEDC-OO1 -7-positioned elsewhere on the tub / basin no, such as on the overflow plate in a bathtub installation, allowing for remote operation of the drain stopper 100.
[0036] In an embodiment, the stopper can incorporate an increased opening height to support the expandable sealing element. This design choice ensures adequate space for the sealing element to expand or contract, optimizing the plunging action without requiring any alterations to existing plumbing assemblies.
[0037] In some embodiments, the height may not need to be adjusted, as some existing stoppers may already open high enough to accommodate the plunging seal. The factor is not necessarily the absolute height, but rather that the stopper must move enough to allow the seal to generate sufficient suction and pressure to effectively clear clogs. This flexibility in design allows the plunging functionality to be adapted to various existing drain configurations with minimal modifications.
[0038] Figure 2 illustrates a perspective view of a drain stopper 200 in a partially extended position, according to an embodiment of the disclosure. The drain stopper 200 includes the same components shown in Figure 1, including a cap 102, a plunging seal 104, and a central shaft 106, installed in a tub / basin 110.
[0039] In this partially extended position, the plunging seal 104 is shown in a state between fully expanded and fully contracted. The accordion-like structure of the plunging seal 104 is partially compressed compared to the fully open position shown in Figure 1. This intermediate state creates upward suction within the drain assembly as indicated by the upward-pointing arrows near the central shaft 106.
[0040] The cap 102 remains at the top of the assembly but has moved slightly upward from its position in Figure 1. This upward movement of the cap 102 and central shaft 106 causes the plunging seal 104 to begin contracting, which creates the suction effect.
[0041] The central shaft 106 extends through the plunging seal 104 and provides structural support for the assembly during the transition between positions. As the drain stopper 200EDC-OO1 -8-moves from the open position toward the closed position, the central shaft 106 guides this movement to ensure proper operation of the plunging mechanism.
[0042] The tub / basin 110 remains unchanged from Figure 1, housing the drain stopper 200. The upward suction generated in this partially extended position is particularly effective for drawing obstructions upward from the drain pipe.
[0043] This partially extended position represents an operational state of the drain stopper 200. When a user operates the drain stopper 200 according to its specific configuration (e.g., pop-up, lift-and-turn, twist-lock), the transition from open to closed position creates this suction effect. As the flexible plunging seal 104 moves from expanded to contracted states, it generates suction that draws clog-causing debris upward. This action helps to dislodge and remove blockages without requiring external plunging tools or chemical cleaners.
[0044] The upward suction generated in this position can be particularly effective for loosening and removing hair, soap residue, and other common drain-clogging materials. A user can create multiple suction cycles to progressively clear stubborn clogs by repeating the transition between open and partially extended positions.
[0045] Figure 3 illustrates a perspective view of a drain stopper 300 in a fully closed position, according to an embodiment of the disclosure. The drain stopper 300 includes the components shown in previous figures, including a cap 102, a plunging seal 104, and a central shaft 106, installed in a tub / basin 110.
[0046] In this fully closed position, the plunging seal 104 is shown in its completely contracted state. The accordion-like structure of the plunging seal 104 is fully compressed compared to the open position shown in Figure 1 and the partially extended position in Figure 2. This contracted state creates downward pressure within the drain assembly as indicated by the downward-pointing arrows near the central shaft 106.
[0047] The cap 102 remains at the top of the assembly but has moved downward to its lowest position. This downward movement of the cap 102 and central shaft 106 causes theEDC-OO1 -9-plunging seal 104 to fully contract, which creates the downward pressure effect while simultaneously sealing the drain opening to prevent water passage.
[0048] The central shaft 106 extends through the plunging seal 104 and provides structural support for the assembly in this closed position. The central shaft 106 maintains alignment of the components and ensures that the plunging seal 104 creates an effective seal against the drain opening.
[0049] The tub / basin 110 remains unchanged from previous figures, housing the drain stopper 300. The downward pressure generated in this fully closed position is particularly effective for forcing obstructions downward through the drain pipe.
[0050] This fully closed position can serve as a conventional drain closure to prevent fluid passage and generate significant downward pressure that can dislodge clogs. When a user operates the drain stopper 300 according to its specific configuration, the transition from partially extended to fully closed position creates this pressure effect. As the flexible plunging seal 104 reaches its fully contracted state, it forces water and air downward through the drainpipe, helping to push clog-causing debris through the system.
[0051] The downward pressure generated in this position can be particularly effective for dislodging solid obstructions and pushing them further down the drain where pipe diameter may increase. By alternating between the positions shown in Figures 1, 2, and 3, a user can create suction and pressure cycles that mimic the action of a traditional plunger but with the convenience of an integrated drain closure mechanism.
[0052] Figure 4 illustrates a perspective view of a pop-up drain stopper 400, according to an embodiment of the disclosure. This figure depicts a standard pop-up drain stopper with an integrated sealing functionality, as described in previous figures.
[0053] The pop-up drain stopper 400 includes a cap 102 positioned at the top of the assembly. The cap 102 has a circular, slightly domed shape that serves as both the visible portion of the stopper when installed and the interface for operation. Cap 102 can accommodateEDC-OO1 -10-the plunging functionality while maintaining a standard drain stopper’s familiar appearance and operation.
[0054] A central shaft 106 extends downward from the cap 102 and forms the main structural component of the assembly. It has a cylindrical upper portion that transitions to a lower structure designed to interact with the drain mechanism. This shaft supports the plunging action while also raising and lowering the stopper.
[0055] At the lower portion of the assembly is a linkage mechanism 402 that connects to the drain’s existing pop-up assembly. This linkage mechanism 402 allows the modified stopper to be operated by the same lever or knob that would control a conventional pop-up drain, maintaining compatibility with standard bathroom fixtures. The design of the linkage mechanism 402 includes cutouts and connection points that facilitate proper movement and operation within the drain system.
[0056] The plunging seal 104 is integrated between the cap 102 and the linkage mechanism 402, surrounding the central shaft 106. When installed, this modified pop-up drain stopper 400 provides the dual functionality of traditional drain closure and integrated plunging capability without requiring modifications to existing plumbing fixtures.
[0057] This design represents a practical application of the plunging seal concept in a widely used drain stopper format, demonstrating how the technology can be adapted to familiar plumbing fixtures. The modified pop-up drain stopper 400 can be installed as a replacement for standard pop-up stoppers, providing enhanced functionality without changing the user experience or requiring special installation procedures.
[0058] Figure 5 illustrates a perspective view of a sink assembly 500 incorporating the modified drain stopper 100 with plunging seal 104, according to an embodiment of the disclosure. The sink assembly 500 depicts a typical bathroom or kitchen sink with the integrated drain stopper 100 installed in its normal operating environment.EDC-OO1 -li
[0059] The sink is shown as a rectangular basin with rounded corners and a flat bottom surface. At the center bottom of the sink basin is the drain opening where the drain stopper 100 is installed. The drain stopper 100 includes a cap 102 that sits flush with or slightly raised from the sink basin surface. By alternating between a closed and open position for the drain stopper 100, the plunging seal 104 beneath the cap 102 can compress and decompress, creating a downward pressure when operated.
[0060] The sink assembly 500 also includes standard fixtures such as hot and cold water controls 502 positioned at the rear edge of the sink. A faucet 504 extends from between the control knobs, arching over the sink basin to deliver water.
[0061] This illustration demonstrates how the drain stopper 100 with plunging seal 104 can integrate seamlessly into conventional sink designs without requiring modifications to the fixture. From this perspective, the drain stopper appears similar to standard drain closures, maintaining the sink’s aesthetic appearance while providing enhanced functionality. The installation preserves normal sink operations while adding the integrated plunging capability for addressing clogs directly at their source.
[0062] The sink assembly 500 represents one of many potential applications for the drain stopper with plunging seal, showing how the technology can be implemented in common household fixtures. This practical implementation allows users to maintain and clear drains without needing separate plunging tools or chemical cleaners, all while preserving the familiar appearance and operation of standard sink fixtures.
[0063] Figure 6 illustrates a perspective view of an embodiment of a drain stopper 600, according to the disclosure. This embodiment features a cup-style plunging seal 602, which represents a variation from the accordion-style plunging seal 104 shown in previous figures. The drain stopper 600 maintains the same core components, including cap 102 and the central shaft 106 extending through the assembly, all installed in a tub / basin 108.EDC-OO1 -12-
[0064] The cap 102 at the top of the assembly retains a similar dome-shaped design as in previous embodiments, providing a familiar user interface for operation. However, beneath the cap 102, the plunging seal 602 forms a flexible cup or bell shape rather than the accordion-style folds shown in earlier figures. This cup-style design creates a different mechanical action during operation while serving the same dual purpose of drain closure and plunging functionality.
[0065] The cup-style plunging seal 602 can feature a wider, flared bottom edge that creates a seal against the drain opening when in the closed position. This design may provide different performance characteristics than the accordion style, potentially offering stronger suction or improved sealing in certain applications. The flexible material of the cup-style seal allows it to deform and create pressure or suction as the stopper is operated, similar to a traditional plunger’s cup design.
[0066] Water flow 108 is indicated by directional arrows on the sides of the assembly, showing how the cup-style seal interacts with water during operation. The tub / basin 110 remains unchanged from previous embodiments, demonstrating that this alternative design can be implemented in the same fixtures as the accordion-style version.
[0067] The drain stopper concept is adaptable to incorporate various plunging technologies beyond the accordion-style and cup-style seals explicitly illustrated. The plunging seal may utilize any effective plunger shape or mechanism.
[0068] For example, the plunging seal could implement bellows-style configurations, multistage compression designs, variable-thickness membranes, dual-action seals that provide different pressure characteristics in different directions, flange-reinforced edges for enhanced sealing, or hybrid designs combining multiple plunging technologies.
[0069] The plunging seal may incorporate advanced materials with specialized properties such as memory-retention polymers, self-healing surfaces, or composite structures with varying flexibility zones. The principle of creating pressure differentials through controlled deformation of a flexible sealing element remains consistent across these various implementations, while theEDC-OO1 -13-specific geometry, material composition, and mechanical action may be optimized for particular applications or improved performance characteristics.
[0070] This embodiment showcases the versatility of the drain stopper concept, illustrating how different sealing element designs can be incorporated while maintaining the core functionality of integrated drain closure and plunging capability. The cup-style design may be preferable in certain applications where its specific mechanical properties offer advantages over the accordion-style approach, providing users with options based on their plumbing configuration or clog-clearing needs.
[0071] It should be appreciated that the drain stopper with the plunging seal for closing a drain and clearing clogs without requiring separate tools or chemical cleaners is not necessarily limited to the embodiments disclosed. Further, the drain stopper may be implemented with other features and configurations.
[0072] For example, in an embodiment, the drain stopper can be equipped with a spring-powered actuation mechanism similar to standard push-button drain stoppers. This allows users to press downward— using a hand or foot— to engage the closed position, and press again to unlock and open. The flexible plunging seal in this configuration expands and contracts during each activation, generating suction and pressure to dislodge clogs without requiring external tools.
[0073] In an embodiment, the drain stopper may be configured for recessed or inverted installation beneath the sink or within a recessed drain opening. In this orientation, the open position corresponds to the stopper being fully lowered, while upward motion causes the expandable sealing element to create suction from below, effectively pulling obstructions upward and out of the drain.
[0074] In some embodiments, the drain stopper can incorporate actuators to suit different user preferences and installation environments. These may include protruding handles, levers, rotary knobs, foot-operated pedals, or electronic touch-sensitive controls, which can be used inEDC-OO1 -14-place of or in combination with a spring-powered mechanism. These actuator options may be constructed from different materials or finished in various colors to match bathroom or kitchen aesthetics.
[0075] In one or more embodiments, performance enhancements may include an optional internal one-way valve to prevent backflow. By maintaining a directional flow of air or fluid, this valve can enhance the device’s plunging efficiency, particularly during the transition from a closed to an open position. Certain embodiments may also integrate a mechanical or visual indicator, such as a color-coded marker or movable gauge, to provide real-time feedback regarding water flow, clog severity, or overall device status.
[0076] In embodiments, the adaptability of the drain stopper extends to its sealing mechanisms, which can be offered in a variety of shapes, materials, or sizes to accommodate different drain geometries and user needs. Interchangeable sealing elements allow for replacement or upgrades depending on specific applications or as parts wear over time.
[0077] In some embodiments, the drain stopper includes electric or battery-powered circuits that automate the open / close cycle, reducing manual effort. In an embodiment, the de-clogging operation may be performed based on a schedule or a configurable schedule. Actuation could be triggered by a push-button on the stopper itself or by remote control, simplifying operation for those with limited mobility.
[0078] In an embodiment, a smart drain stopper is equipped with sensors and wireless connectivity to detect forming clogs based on fluid flow characteristics and transmit alerts to a user’s mobile device, potentially performing automatic plunging cycles before clogs become severe.
[0079] In some embodiments, the drain stopper may include integrated lighting to help users visually inspect the drain or confirm device operation in low-light conditions. Further, the lighting can serve as an indicator for open / closed status or for detecting internal obstructions. To enhance longevity and serviceability, various parts of the drain stopper— such as the sealingEDC-OO1 -15-element, valve assemblies, or actuator components— ay be made readily detachable, simplifying cleaning, maintenance, and eventual replacement.
[0080] Some embodiments may offer adjustable suction strength by allowing users to modify the internal volume or geometry of the sealing element. This adjustability can enable the device to be tailored to different clog severities, drain diameters, and flow conditions, with models ranging from light-duty household versions to heavy-duty commercial variants.
[0081] It should be understood that while various actuation mechanisms are described individually throughout this disclosure (such as push-button, lever, twist-lock, rotary handle, foot pedal, recessed, or electronically controlled actuators), these mechanisms are not mutually exclusive. In various embodiments, combinations of two or more actuation mechanisms may be implemented together in a single drain stopper.
[0082] For example, a drain stopper may incorporate a manual lever and an electronic control system, or a twist-lock mechanism that also includes foot pedal activation. Such combinations may provide enhanced functionality, accessibility options for different users, or redundancy in operation. The specific combinations of actuation mechanisms may be selected based on the intended application, user preferences, or installation environment.
[0083] Figure 7 illustrates a flowchart of an embodiment method 700 for clearing a drain clog using the drain stopper, according to an embodiment of the disclosure. In various embodiments, the method may include additional or fewer steps, or the steps may be performed differently than illustrated.
[0084] At step 702, the user positions the drain stopper in a drain opening such that the expandable sealing element is disposed within the drain opening. This initial installation ensures the drain stopper is seated correctly and ready for operation.
[0085] At step 704, the user actuates the drain stopper to force fluid and air through the drain pipe. Depending on the nature and location of the clog, this actuation can push debrisEDC-OO1 -16-further into the pipe or dislodge it from its position. The movement of fluid and air creates pressure differentials that help break apart accumulated materials blocking the drain.
[0086] At step 706, the user actuates the drain stopper in a different direction, creating suction within the drain pipe. This suction effect can draw debris in various directions depending on the position and orientation of the drain stopper relative to the drain. The pressure differential generated helps mobilize and remove materials loosened during the previous actuation step.
[0087] The user can repeat steps 704 and 706 as necessary until the drain is substantially clear. All these operations are performed without external plungers, chemical agents, or additional plumbing modifications, making the method convenient and environmentally friendly.
[0088] In embodiments, plunging seals may be manufactured and sold separately from the complete drain stopper assembly. This modular approach allows users to modify their existing drain stoppers into plungers by replacing the standard seal with a plunging seal. Such aftermarket components can be designed to fit common drain stopper models and brands, providing an economical upgrade path for consumers who wish to add plunging functionality without replacing their entire drain assembly. These replacement plunging seals maybe offered in various sizes, shapes, and materials to accommodate different drain stopper designs and plumbing configurations. The separate availability of plunging seals also facilitates maintenance, as users can replace worn seals without purchasing an entirely new drain stopper. Manufacturers may provide installation guides or adapters to ensure compatibility with a wide range of existing drain stoppers, further expanding the accessibility and adoption of the plunging seal technology.
[0089] Figure 8 illustrates a block diagram of a system 800, according to an embodiment of the disclosure. The system 800 includes a processor 802, memory 804, a sensor 806, an interface 808, and a drain stopper 810, communicatively coupled via a bus 812. System 800EDC-OO1 -17-may include additional components not shown, such as power management circuitry, antennas, transceivers, or additional sensors.
[0090] Processor 802 serves as a controller for the system 800. It may include a microprocessor, microcontroller, digital signal processor (DSP), application-specific integrated circuit (ASIC), field-programmable gate array (FPGA), or other suitable processing device. The processor 802 executes instructions stored in the memory 804 to operate the drain stopper 810 according to various operational modes and user preferences. In some embodiments, the processor 802 may be a low-power processor suitable for battery-powered applications. It an embodiment, processor 802 maybe a more powerful processor for handling complex drain monitoring algorithms and wireless communication protocols in some embodiments.
[0091] Memory 804 may include non-transitory and transitory memory storage. Non-transitory memory may include read-only memory (ROM), flash memory, electrically erasable programmable read-only memory (EEPROM), hard drives, optical discs, or other persistent storage media. Transitory memory may include random-access memory (RAM) for temporary storage of variables and operational data during execution. Memory 804 can store instructions that, when executed by the processor 802, cause the processor to perform various operations, including actuating the drain stopper 810 between open and closed positions, processing sensor data, managing user interface interactions, and controlling wireless communications.
[0092] In embodiments, interface 808 allows users to interact with the system 800 to adjust settings, initiate manual plunging cycles, or receive status information. It may include physical controls such as buttons, switches, or touch-sensitive surfaces, as well as visual indicators like LEDs, LCD displays, or color-changing elements. In some embodiments, interface 808 may include wireless communication capabilities that allow users to control the drain stopper 810 or receive notifications through a mobile application or smart home system.
[0093] Sensor 806 monitors conditions related to the drain stopper 810 or surrounding plumbing environment. It may include flow sensors to detect water movement, pressure sensorsEDC-OO1 -18-to identify potential clogs, optical sensors to detect debris, or moisture sensors to identify leaks. Processor 802 processes data from sensor 806 to determine if the drain is clogged, allowing the system to address developing blockages before they become severe.
[0094] The drain stopper 810 corresponds to the drain stopper embodiments disclosed throughout this application, with additional electronic and automated features enabled by the system 800. The drain stopper 810 may include an electro-mechanical actuator (e.g., actuators, motors, or solenoids) controlled by processor 802 to move between open and closed positions, creating the suction and pressure needed to clear drain clogs.
[0095] The bus 812 provides a communication pathway between the various components of the system 800, allowing data and control signals to be exchanged. The bus 812 may implement various communication protocols suitable for the specific application requirements.
[0096] In embodiments, system 800 can perform automated functions based on the electrical features disclosed. For example, the processor 802 may execute instructions to operate the drain stopper 810 on a configurable schedule, performing regular maintenance plunging cycles during periods of low drain usage. The processor 802 may analyze data from the sensor 806 to detect early signs of clogging, such as slower drainage rates, and automatically initiate plunging actions before a complete blockage occurs.
[0097] The system 800 may implement adaptive learning algorithms stored in memory 804 and executed by processor 802 to optimize plunging effectiveness based on historical clog patterns and user feedback. For instance, if certain plunging sequences prove more effective for a particular drain, the system can prioritize those sequences in future operations.
[0098] The interface 808 may enable remote monitoring and control capabilities, allowing users to check the drain status or initiate plunging cycles from anywhere via a smartphone or other connected device. The system 800 can integrate with broader smart home ecosystems, coordinating with water usage patterns from other appliances to optimize drain maintenance timing.EDC-OO1 -19-
[0099] Through this integrated electronic approach, the system 800 can transform the drain stopper from a simple mechanical device into an intelligent, proactive drain management solution that can reduce the frequency and severity of clogs while minimizing the need for user intervention or harsh chemical cleaners.
[0100] The drain stopper with plunging seal provides several advantages over conventional drain maintenance solutions. Integrating plunging functionality directly into the drain stopper eliminates the need for separate external plunging equipment that typically requires storage space, regular cleaning, and manual retrieval when needed. This integration makes clog management more accessible, immediate, and convenient for users across residential, commercial, and industrial settings.
[0101] The design offers environmental and infrastructure benefits by reducing reliance on chemical drain cleaners, which can damage plumbing systems through corrosive action, harm water treatment facilities, and introduce toxic substances into the water supply. The mechanical action of the plunging seal effectively addresses organic and inorganic blockages that chemical solutions may fail to dissolve.
[0102] Another advantage lies in the compatibility with existing plumbing systems. The drain stopper can be installed in standard drain openings without requiring specialized tools, additional components, or modifications to existing plumbing. This drop-in replacement capability significantly lowers the barrier to adoption and makes the technology accessible to users, from homeowners to facility managers.
[0103] The intuitive operation of the drain stopper enhances user experience by maintaining familiar interactions while adding functionality. Users can clear clogs using the same motions to open and close drains, eliminating the learning curve typically associated with new plumbing tools. This intuitive design promotes regular preventative maintenance rather than reactive clog management, potentially reducing the frequency and severity of drain blockages over time.EDC-OO1 -20-
[0104] From a sanitary perspective, the integrated design keeps all plunging components within the drain system, eliminating the cross-contamination risks associated with traditional plungers that may transfer bacteria between different drains or surfaces. This feature can be particularly valuable in healthcare facilities, food service environments, and other settings where hygiene is paramount.
