Description

Technical Field

[0001] This utility model relates to a flap valve, specifically an electric flap valve for a water tank. Background Technology

[0002] Traditional kitchen sink waste collection typically involves installing a filter, such as a strainer basket, above the sink drain, or a sedimentation device at the end of the drain pipe. However, filters, located above the drain, often slow down drainage, while sedimentation devices require frequent cleaning to prevent blockages. Furthermore, both methods have limited capacity, requiring users to repeatedly remove and re-collect waste, resulting in a poor user experience. Therefore, the best solution is to add a flap valve to the bottom of the sink drain. When draining, the flap valve closes, allowing wastewater to drain through a side channel, while the remaining wastewater is discharged into the waste bin through the open flap valve. This addresses the shortcomings of existing designs.

[0003] However, existing flap valves are mostly used as unloading devices on equipment in metallurgy, building materials, and mining, and their structural design cannot meet the sealing requirements of liquid media. Furthermore, these industrial flap valves are bulky and complex, making them unsuitable for installation in the narrow space under a household kitchen sink. Although butterfly valves used in water pipes have a similar flap structure to flap valves, and offer better sealing performance and smaller installation dimensions, their single flap structure and centrally located rotating shaft mean that the discharge channel is still partially obstructed when the valve is open. Therefore, if butterfly valves are directly used in place of flap valves in kitchen sinks, this design flaw of the butterfly valve makes it easy for larger food waste, such as vegetable leaves and fruit cores, to be obstructed during discharge, affecting normal user experience.

[0004] Therefore, there is an urgent need to develop a new type of kitchen sink flap valve that can ensure good sealing performance, provide a smooth waste discharge channel, and adapt to the narrow space under the kitchen sink for installation. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a water tank electric flap valve that can achieve unobstructed garbage discharge, reliable sealing performance after closure, and adaptability to installation in narrow spaces.

[0006] The technical problem of this utility model is solved by the following technical solution:

[0007] An electric flap valve for a water tank includes an electric actuator and flaps, and a mounting frame. Two electric actuators are provided outside the mounting frame, and two flaps are provided inside the mounting frame. One side of each flap is rotatably mounted inside the mounting frame via a flap shaft, and the other side is a suspended side. The two flaps are independently driven by their respective electric actuators to open and close at 90° relative to the plane of the mounting frame, and drive the suspended sides of the two flaps to rotate relative to each other to form an alternating opening and closing structure.

[0008] The two flaps are provided with mutually cooperating inclined structures on their suspended sides, including an upper inclined surface on the suspended side of one flap and a lower inclined surface on the suspended side of the other flap; when the flaps are closed in an alternating manner, the upper inclined surface and the lower inclined surface press against each other to seal.

[0009] The flap adopts an adhesive-coated structure, including a substrate and an elastic sealing layer covering the outer surface of the substrate.

[0010] The flap shaft and the flap are connected by a non-circular cross-section transmission connection.

[0011] It also includes time relays, which remotely control the sequential start of the two electric actuators to drive the staggered opening and closing of the two flaps.

[0012] The two flaps rotate sequentially to either the horizontal plane to form a closed shape or to the vertical plane to form an open shape.

[0013] Each flap is equipped with a limiting member above it. The two flaps rotate to the horizontal plane one after the other and are blocked and limited by the limiting member to form a closure.

[0014] One end of the flap shaft extends from one side of the mounting frame and connects to the electric actuator, while the other end extends from the opposite side of the mounting frame and is rotatably supported inside the end cover.

[0015] The mounting frame is a square frame structure, the two flaps are arranged side by side, and the two electric actuators are arranged diagonally.

[0016] The top of the mounting frame is provided with an integrally extended upward connecting frame, and the mounting frame is fixed to the drain outlet of the water tank via the connecting frame.

[0017] Compared with existing technologies, this utility model mainly adds an installation frame with two electric actuators outside the frame. Inside the frame are two flaps, each with one side rotatably mounted within the frame via a flap shaft, and the other side suspended. The two flaps are then independently driven by their respective electric actuators to open and close at 90° relative to the plane of the installation frame, causing the suspended sides of the two flaps to rotate relative to each other, forming an alternating opening and closing structure. Therefore, the improved electric flap valve can completely avoid the discharge channel, achieving unobstructed waste discharge. Simultaneously, the alternating opening and closing structure formed by the relative rotation of the suspended sides of the two flaps, combined with the mutually cooperating pressure sealing inclined structure, provides stronger sealing performance, thereby improving the anti-leakage capability after the flap valve is closed. Furthermore, the entire flap valve can be independently installed at the drain outlet of the sink via an integrally extended upward connecting frame at the top of the installation frame, achieving a modular, individual design. This results in a simple structure and compact size, making installation more convenient and quick even in narrow sink bottom spaces. Attached Figure Description

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] like Figures 1-6 As shown, 1. Electric actuator, 2. Flip plate, 21. Base plate, 22. Elastic sealing layer, 23. Upper inclined surface, 24. Lower inclined surface, 25. Hexagonal hole, 3.

Waste collection bin. The same labels in each figure represent the same components.

[0026] An electric flip valve for kitchen sinks is mainly used for the collection and discharge of food waste from kitchen sinks, specifically as follows: Figure 6 As shown, the flap valve is first closed to filter and discharge the sewage in the water tank 6 through the drainage channel on the side of the drain outlet. Then, the kitchen waste that has been filtered and deposited in the water tank 6 is discharged separately into the garbage collection bin 7 through the discharge channel 61 after the electric flap valve at the bottom of the drain outlet is opened, thereby realizing the collection of large-capacity kitchen waste.

[0027] The electric flap valve includes a mounting frame 3, two electric actuators 1 and two flaps 2, with the two electric actuators 1 arranged diagonally outside the mounting frame 3 and the two flaps 2 arranged side by side inside the mounting frame 3.

[0028] The mounting frame 3 is a square frame structure, and an integrally extended upward connecting frame 31 is provided at the top of the mounting frame 3. The connecting frame is also a square frame structure. Multiple circumferentially arranged triangular ribs 32 are provided between the connecting frame 31 and the mounting frame 3 for structural reinforcement. The connecting frame 31 can be fixed to the drain outlet of the water tank 6 by adhesive bonding. Figure 6 As shown, the entire flap valve can be independently installed at the bottom of the drain outlet of the water tank 6 directly through the connecting frame 31, thus realizing the modular design of the flap valve. It has a simple structure and small size, so it can be installed more conveniently and quickly even in the narrow space at the bottom of the water tank.

[0029] Of course, the shape of the connecting frame 31 needs to be adapted to the bottom of the drain outlet. That is, the connecting frame in this embodiment is a square frame structure, so the bottom of the drain outlet is a square drain outlet. If the bottom of the drain outlet is a circular drain outlet, the connecting frame 31 can be designed as a corresponding circular frame structure.

[0030] Then, one side of each flap 2 is rotatably mounted in the mounting frame 3 via the flap shaft 5, while the other side is suspended, that is, as shown in the image. Figure 3 As shown, the two flaps 2 are mounted on opposite sides of the mounting frame 3 via flap shaft 5, while the other side of the two flaps 2 is close to each other as the suspended side. Therefore, the two flaps 2 after opening are located on both sides of the discharge channel 61 and will not block the discharge of kitchen waste.

[0031] Meanwhile, the design of two flaps 2 has a shorter switching stroke and faster speed compared to the single flap design. In particular, when the water tank is draining, the two flaps 2 that are closed to each other can also share the impact force of the water flow, so as to reduce the torque on the flap shaft 5.

[0032] The flap shaft 5 and flap 2 are connected by a non-circular cross-section transmission connection. For example, in this embodiment... Figure 2The transmission connection is achieved using a hexagonal cross section. Specifically, the flap shaft 5 passes through a hexagonal shaft 51 into a hexagonal hole 25 on one side of the flap 2. Both ends of the flap shaft 5 protrude from both sides of the mounting frame 2. One end of the flap shaft 5 protrudes from one side of the mounting frame 2 and connects to the electric actuator 1, while the other end protrudes from the opposite side of the mounting frame 2 and is rotatably supported within the end cover 4. In this embodiment, the other end of the flap shaft 5 is directly inserted into the end hole 41 of the end cover 4. A clearance fit is sufficient for rotatable support. Therefore, after the electric actuator 1 drives the flap shaft 5 to rotate, this transmission structure can synchronously rotate the flap 2 within the mounting frame. In this embodiment, the two flaps 2 are independently driven by their respective electric actuators 1 to open and close at 90° relative to the plane of the mounting frame 3, thereby causing the suspended sides of the two flaps 2 to rotate relative to each other, forming an interlaced opening and closing structure.

[0033] Typically, the two flaps 2 are rotated one after the other to the horizontal plane to form a closed mechanism, or rotated one after the other downwards to the vertical plane to form an open mechanism.

[0034] The electric actuator 1 and the end cap 4 are respectively connected to the outside of the mounting frame 3 by screwing. This screw connection method is convenient for both installation and disassembly and maintenance.

[0035] Meanwhile, the suspended sides of the two flaps 2 are respectively provided with mutually cooperating inclined structures, mainly including an upper inclined surface 23 set on the suspended side of one flap and a lower inclined surface 24 set on the suspended side of the other flap. The inclination angle of the upper inclined surface 23 and the lower inclined surface 24 can be selected from 15° to 30°. When the flaps 2 are closed in an alternating manner, the upper inclined surface 23 and the lower inclined surface 24 can press against each other to achieve a seal, so as to ensure that the two flaps 2 do not leak water when the water tank 6 discharges sewage.

[0036] To improve sealing performance, the flap 2 can adopt a rubber-coated structure, including a substrate 21 and an elastic sealing layer 22 covering the outer surface of the substrate. The substrate 21 can be a metal substrate, and the elastic sealing layer 22 can be made of rubber. A limiting member 33 is also provided above each flap 2. The limiting member is close to the flap shaft 5. When the two flaps 2 rotate to the horizontal plane one after the other, they can be blocked and limited by the limiting member 33. This can prevent the flaps 2 from continuing to flip upward and leaving the closed position, and can also cooperate with the pressing and sealing of the upper inclined surface 23 and the lower inclined surface 24 to ensure the reliability of the closed structure.

[0037] In addition, the electric flap valve can also be equipped with a time relay (not shown in the figure), which can remotely control the two electric actuators 1 to start sequentially with a time difference of 0.5 seconds to 2 seconds, thereby driving the two flaps 2 to open and close alternately, and also avoiding the trouble of manually operating the valve in the narrow bottom space of the water tank 6.

[0038] This invention allows the flap 2 to completely avoid the discharge channel 61, thus enabling unobstructed garbage discharge. Then, the two flaps rotate relative to each other on their suspended sides to form staggered opening and closing, and with the mutual pressing and sealing of the upper inclined surface 23 and the lower inclined surface 24, they can have stronger sealing performance, thereby greatly improving the anti-leakage ability of the flap valve after it is closed and preventing odors from rising. Next, the entire flap valve can be directly and independently installed at the drain outlet of the water tank 6 through the connecting frame 31, realizing a modular and independent design structure, so it can be installed more conveniently and quickly even in the narrow space at the bottom of the water tank.

[0039] The basic principles and main features of this utility model have been described above. Those skilled in the art should understand that this utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the utility model as claimed. The scope of protection of this utility model is defined by the appended claims and their equivalents.
