Description

Technical Field

[0001] This utility model relates to the field of sanitary ware technology, and in particular to a drain valve and a toilet. Background Technology

[0002] Currently, toilets on the market typically require a matching adapter to connect the toilet's drain outlet to the floor's drainage channel. This not only results in a complex structure but also takes up a lot of space. To address this, toilets with integrated drainage systems have emerged. The core component of these systems is the drain box, or drain valve, which uses a motor to drive the drain pipe to align with the drain outlet, thus achieving the purpose of drainage. However, while this drainage system achieves the desired drainage effect, the drain pipe needs to rotate completely. This requires a large enough space within the drain box to accommodate the entire drain pipe's free rotation, coupled with the drive motor. Consequently, the space utilization within the drain box is very low, resulting in a large overall size and poor flexibility, making it prone to malfunctions and blockages. Utility Model Content

[0003] The purpose of this utility model is to design a drain valve and toilet to overcome the shortcomings of the above-mentioned technologies.

[0004] This utility model designs a drain valve, including a housing with a cavity inside. The housing has an inlet and an outlet communicating with the cavity. A drain pipe is provided inside the cavity, with an inlet and an outlet at its two ends. At least a portion of the drain pipe between the inlet and outlet is flexible and easily bent. The inlet end of the drain pipe is connected to the inlet. A driving mechanism is provided between the housing and the outlet end of the drain pipe. The drain pipe bends and deforms under the drive of the driving mechanism, causing the outlet end to switch back and forth between being aligned with and offset from the outlet.

[0005] Preferably, the drain pipe is a corrugated pipe or a section of the pipe between the inlet and outlet is a corrugated pipe.

[0006] Further optimization involves forming a flange structure at the inlet end, with a first connection hole on the flange structure. A fixing ring is provided between the inner wall of the housing at the inlet and the flange structure, with a second connection hole corresponding to the first connection hole on the fixing ring. A third connection hole is provided at the inlet of the housing. The first, second, and third connection holes are connected by threaded fasteners, thereby fixing the inlet end of the sewage pipe to the inlet of the housing.

[0007] Further optimization involves a drive mechanism comprising a gearbox, a rotating shaft, rotating arms, and a positioning ring. The gearbox contains a motor and a worm gear set. The worm gear set includes a worm and a gear set. The motor connects to and drives the worm to rotate. The worm and the gear set cooperate with each other. Two rotating arms are symmetrically connected to the outer wall of the positioning ring. The gear set is connected to one of the rotating arms via a rotating shaft. The other rotating arm is rotatably connected to the inner wall of the cavity. The positioning ring is fitted onto the outlet end of the sewage pipe.

[0008] Further optimization involves providing a docking ring at the outlet port, with the positioning ring fitted onto the docking ring, and the outward-facing port of the docking ring forming a docking interface with the outlet.

[0009] Further optimization involves two symmetrically distributed ears on the positioning ring, with two rotating arms connected to the corresponding ears. The end face of the water outlet has two symmetrical protrusions, and the two ears have slots for the corresponding protrusions to pass through and form a positioning hole. The outer peripheral wall of the docking ring forms a convex edge, and the convex edge has a groove. The top of the protrusion passes through the slot and is inserted into the groove to form a positioning hole.

[0010] Further optimization involves the positioning ring comprising two semi-rings, each semi-ring having a pair of ears at both ends. After the two semi-rings are joined together, their corresponding pairs of ears also fit together. The pairs of ears are fixedly connected by fasteners, thus forming a complete ear and positioning ring. Two rotating arms are respectively connected to one pair of ears on each side.

[0011] Further optimization involves the housing comprising a main body and a cover, with the cavity located within the main body, the main body having an opening communicating with the cavity, the cover being detachably connected to the opening of the main body, and the gearbox located on the cover.

[0012] Preferably, when the water outlet is offset from the water outlet, the water outlet is in an upward bent state relative to the sewage pipe. At this time, water is poured into the sewage pipe to form a water seal inside the sewage pipe.

[0013] This utility model also designs a toilet, which includes the above-mentioned drain valve.

[0014] The technical advantage of this invention is that the shell has an inlet and an outlet. The two ends of the drain pipe inside the shell are the inlet and outlet, respectively. The inlet is fixedly connected to the inlet, and the outlet is connected to the shell via a drive mechanism. The drive mechanism drives the outlet to rotate so that it aligns with the outlet, or it rotates in the opposite direction to avoid aligning with the outlet. The section of the drain pipe between the inlet and outlet is made of a flexible material, either partially or entirely. This allows the drain pipe to be rotated only at the outlet, eliminating the need for overall rotation. This significantly improves space utilization and saves internal space. The overall volume of the casing is reduced, and the flexibility of the drain pipe is greatly improved by simply rotating the water outlet end, making it more flexible to rotate and thus reducing the failure rate. Toilets equipped with this drain valve have a lower failure rate, smaller size, and longer service life. The water inlet end is fixed, unlike the rotating connection of the water inlet end on the market. This strengthens the seal between the water inlet end and the water outlet to prevent water leakage. When the water outlet end is offset from the water outlet, the water outlet end is in an upward bending state relative to the drain pipe. At this time, after the water from the toilet enters the drain pipe, a water seal is formed at the bend of the drain pipe, which can prevent odors from entering the water inlet.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0025] This utility model includes a drain valve, which includes a housing 1, with a cavity 11 formed inside the housing 1. The housing 1 is provided with an inlet 12 and an outlet 13 communicating with the cavity 11. In this embodiment, the inlet 12 is located above or to the side of the housing 1 to facilitate the entry of toilet wastewater from the inlet 12. The outlet 13 is usually located below the housing 1 to facilitate the discharge of wastewater from the outlet 13. A drain pipe 2 is provided inside the cavity 11. The two ends of the drain pipe 2 are an inlet end 21 and an outlet end 22, respectively. The inlet end 21 of the drain pipe 2 is connected to the inlet 12, and the outlet end 22 of the drain pipe 2 is connected to the outlet 13, so that the wastewater flowing into the cavity 11 through the inlet end 21 can be discharged along the outlet end 22 and the outlet 13.

[0026] At least part of the section of the drain pipe 2 between the inlet end 21 and the outlet end 22 is made of flexible and easily bendable material, making the drain pipe 2 easy to bend or bend. That is, the drain pipe 2 can be made of flexible material in a partial section or the entire drain pipe 2 can be made of flexible material, such as corrugated pipe or rubber pipe, to facilitate bending and bending. For example, the entire drain pipe 2 can be made of corrugated pipe or part of the section between the inlet end 21 and the outlet end 22 can be made of corrugated pipe, so that the drain pipe 2 can be bent or bent at a certain angle.

[0027] Furthermore, the inlet end 21 forms a flange structure 23. A first connecting hole 24 is formed on the side of the flange structure 23 facing the inlet. The first connecting hole 24 is a blind hole. A fixing ring 3 is provided between the inner wall of the housing 1 at the inlet 12 and the flange structure 23. A second connecting hole 31 corresponding to the first connecting hole 24 is provided on the fixing ring 3. A third connecting hole 14 is provided at the inlet 12 of the housing 1. Threaded fasteners enter through the third connecting hole 14. The first connecting hole 24, the second connecting hole 31, and the third connecting hole 14 are connected by threaded fasteners, so that the inlet end 21 of the drain pipe 2 is fixedly connected to the inlet 12 of the housing 1 and forms a seal. Since the drain pipe 2 may be a flexible pipe, it is fixedly connected to the inlet 12 by the fixing ring 3, which facilitates the fixation of the drain pipe 2 and prevents water leakage at the connection.

[0028] In addition, the end face of the fixing ring 3 facing the water inlet 12 is provided with two concentrically distributed circumferential ribs, and the edge of the housing 1 at the water inlet 12 is provided with a circumferential groove 18. The two circumferential ribs are embedded into the circumferential groove 18 to form a limit, thereby strengthening the installation of the fixing ring 3.

[0029] A drive mechanism is provided between the housing 1 and the outlet end 22 of the drain pipe. The drive mechanism includes a gearbox 4, a rotating shaft 5, a rotating arm 6, and a positioning ring 7. The gearbox 4 is fixed outside the housing 1. A motor 41 and a worm gear set are installed inside the gearbox 4. The worm gear set includes a worm 42 and a gear set 43. The motor 41 is connected to and drives the worm 42 to rotate. The worm 42 cooperates with the gear set 43. The rotating shaft 5 passes through the housing 1 and is rotatably connected to the housing 1. One end of the rotating shaft 5 is connected to the gear set 43, and the other end extends into the cavity 11 of the housing 1 and connects to the rotating arm 6. The positioning ring 7 is sleeved on the outlet end 22 of the drain pipe 2. In this embodiment... In the middle, there are two rotating arms 6, which are symmetrically connected to the outer wall of the positioning ring 7. One end of each rotating arm 6 is connected to the two sides of the positioning ring 7, and the other end is connected to the rotating shaft 5 and the inner wall of the cavity 11 respectively. The rotating shaft 5 is rotatably connected to the inner wall of the cavity 11. The rotating shaft 5 rotates under the drive of the gearbox 4, and the rotating shaft 5 drives the rotating arm 6 to rotate. At this time, the outlet end 22 of the sewage pipe 2 rotates, so that the outlet end 22 of the sewage pipe 2 faces the outlet 13 and connects with the outlet 13, thereby connecting the outlet 13 and the sewage pipe 2, so that the sewage in the sewage pipe 2 can be discharged through the outlet end 22 and the outlet 13.

[0030] Wastewater from the toilet enters the drain pipe 2 through the inlet 12. When sewage needs to be discharged, the drive mechanism drives the rotating shaft 5 to rotate, which in turn drives the rotating arm 6 to rotate. The rotating arm 6 then drives the positioning ring 7 to rotate, which rotates around the inner wall of the cavity 11. The positioning ring 7 also drives the outlet end 22 of the drain pipe 2 to rotate. Under the influence of the positioning ring 7, the outlet end 22 rotates toward the outlet 13, thus connecting the outlet end 22 with the outlet 13. In this way, the water in the drain pipe 2 is discharged through the outlet end 22 and the outlet 13. When sewage is not needed... After sewage discharge or sewage discharge is completed, the gearbox 4 drives the rotating shaft 5 to reverse, the rotating shaft 5 drives the rotating arm 6 to reverse, and the positioning ring 7 reverses accordingly, thereby driving the water outlet 22 to reverse, so that the water outlet 22 is separated from the water outlet 13 and staggered, thus stopping sewage discharge. That is, the sewage pipe 2 is bent and deformed under the drive mechanism, so that the water outlet 22 is connected and staggered between the water outlet 13 and the water outlet 13, thereby realizing the situation of sewage discharge or no sewage discharge. The advantage of this design is that it can prevent odor from flowing back up from the water outlet 13 along the sewage pipe 2.

[0031] In addition, the gear set 43 is a conventional technical means, and its specific structure and implementation method will not be described in detail here.

[0032] Furthermore, a docking ring 8 is fitted onto the port of the water outlet 22, and a positioning ring 7 is fitted onto the docking ring 8. The outward-facing port of the docking ring 8 forms a docking interface 81 that docks with the water outlet 13. The docking interface 81 can be formed into a curved shape or various shapes, or a rubber sealing ring can be provided to dock with the water outlet 13, so that the water outlet 22 can directly dock with the water outlet 13 after rotating to the water outlet 13. It should be noted that in this embodiment, a notch is formed on one side of the end face of the docking interface 81, and the notch smoothly transitions with the end face of the docking interface 81, that is, a certain curved concave surface is formed on one side of the docking interface 81. In this way, when the docking interface 81 rotates to dock with the water outlet 13, it can smoothly and naturally dock with the water outlet 13 without the need for additional actions to dock.

[0033] Furthermore, the positioning ring 7 is provided with two symmetrically distributed ears 71, which are integrally connected to the outer peripheral wall of the positioning ring 7. Two rotating arms 6 are respectively connected to the corresponding ears 71. In this embodiment, the rotating arms 6 are also integrally connected to the ears 71. One end of the two rotating arms 6 is connected to the corresponding ears 71, and the other end extends downward to the rotating shaft 5 and the inner wall of the cavity 11, forming a rotatable connection with the rotating shaft 5 and the inner wall of the cavity 11, respectively. It should be noted that a rod-shaped member 17 extends from the inner wall of the cavity 11. The end of the rod-shaped member 17 is provided with a through hole, in which one of the rotating arms 6 is rotatably connected to the through hole by a fastener or pin. The rod-shaped member 17 also serves to support the water outlet end 22, so that the water outlet end 22 can be positioned in a suitable position, which facilitates the rotation and docking of the water outlet end 22.

[0034] Furthermore, the end face of the water outlet 22 is provided with two symmetrical protrusions 25, and the two ears 71 are respectively provided with slots 72. The two protrusions 25 pass through the corresponding slots 72 to form a positioning. The outer peripheral wall of the docking ring 8 forms a protruding edge 82, which can axially limit the positioning ring 7. The protruding edge 82 is provided with a groove 83. The top of the protrusion 25 passes through the slot 72 and is inserted into the groove 83, thereby positioning the docking ring 8, the positioning ring 7 and the water outlet 22 to prevent axial deflection.

[0035] Furthermore, the positioning ring 7 includes two half-rings, each half-ring having a pair of ears 71 at both ends. After the two half-rings are joined together, their corresponding pairs of ears 71 also fit together. A through hole is provided on each pair of ears 71, and a fastener is installed in the hole to fix the two ears 71 together, thereby forming a complete ear 71 and positioning ring 7. Two rotating arms 6 are respectively connected to one pair of ears 71 on each side.

[0036] Furthermore, the housing 1 includes a main body 15 and a cover 16. A cavity 11 is located inside the main body 15. The main body 15 has an opening communicating with the cavity 11. The cover 16 is detachably connected to the opening of the main body 15. The gearbox 4 is located on the cover 16, which facilitates the disassembly of the drain pipe 2.

[0037] Furthermore, after the toilet has finished flushing, the water outlet 22 rotates to be offset from the water outlet 13, that is, the water outlet 22 bends upward. At this time, the water outlet is in an upward bending state relative to the drain pipe 2. At this time, the water coming down from the toilet enters the bend of the drain pipe 2, thereby forming a water seal at the bend of the drain pipe 2, which can prevent odors from rising.

[0038] This utility model also includes a toilet, which includes the above-mentioned drain valve. The toilet also includes a basin cavity, on which a drain outlet is provided. The drain outlet is connected to the water outlet 13 of the shell 1.

[0039] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
