Abstract
Description
Technical Field
[0001] This invention relates to the field of toilet technology, specifically to a water-saving toilet with a low-noise flushing structure. Background Technology
[0002] A toilet, also known as a ceramic toilet, flush toilet, or seated toilet, is a sanitary appliance belonging to the field of building water supply and drainage materials. A toilet is a toilet designed for use by sitting on the floor. According to the flushing method, it can be divided into washdown type, siphon type, jet siphon type, vortex siphon type, and volume direct discharge type. According to the structure of the water tank, it can be divided into wall-mounted tank type, seated tank type, and one-piece type.
[0003] Some existing low-noise toilets store a large amount of water in the tank before each flush, and then flush downwards by gravity. This requires a large amount of water to flush, and the water flow is not ideal. In addition, if paper towels or other objects are thrown into the toilet, it can easily cause blockage and affect the normal use of the toilet. Summary of the Invention
[0004] The purpose of this invention is to address the problems of existing low-noise toilets that require a large amount of water to be stored in the tank before each flush, and then flushed downwards by gravity, resulting in a large water consumption and an unsatisfactory water flow force. Furthermore, if paper towels or other objects are thrown into the toilet, it can easily cause blockage and affect the normal use of the toilet. Therefore, this invention proposes a water-saving toilet with a low-noise flushing structure.

[0006] In a preferred embodiment of the present invention, a water inlet is fixedly connected to one side of the water storage tank, the water inlet is connected to the interior of the water storage tank, four sliding rods are arranged in a rectangle, a sealing ring is fixed to the outside of the piston, and the sealing ring is tightly fitted to the inner wall of the water storage tank.
[0007] In a preferred embodiment of the present invention, the lead screw and the piston are connected by a thread, the lead screw and the first bevel gear rotate synchronously, the first bevel gear and the second bevel gear mesh with each other, the first rotating shaft and the second bevel gear rotate synchronously, and the lead screw and the first rotating shaft rotate synchronously.
[0008] In a preferred embodiment of the present invention, one end of the rotating shaft extends to the outside of the water tank, the transmission gear is fixedly installed on the end of the rotating shaft away from the bevel gear, a limiting groove is provided on one side of the rack, the limiting rod is slidably connected to the limiting groove, and the rack and the transmission gear mesh with each other.
[0009] In a preferred embodiment of the present invention, a second limiting groove is provided on one side of the fixing plate, the second limiting rod is slidably connected to the second limiting groove, and the turntable and the first sprocket rotate synchronously.
[0010] In a preferred embodiment of the present invention, a sewage inlet pipe is connected to one side of the sewage tank, a sewage outlet pipe is connected to one side of the sewage tank, two of each of the rotating shaft two, the crushing blade and the transmission gear two are provided, the two transmission gear two mesh with each other, one end of the rotating shaft two extends to the outside of the main body, the sprocket two is meshed with the sprocket one and a chain is connected, and the output end of the motor is fixed to one end of the rotating shaft two on one side.
[0011] In a preferred embodiment of the present invention, a protective cover is fixedly installed on one side of the main body, the protective cover being located on the side of the motor; a protective cover is fixedly installed on one side of the main body, the protective cover being located outside the two transmission gears; a control panel is fixedly installed on one side of the main body, and the control panel is electrically connected to the motor.
[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. The motor drives the second rotating shaft to rotate, causing the two meshing transmission gears to rotate synchronously in opposite directions. This causes the second rotating shaft to drive the second sprocket to rotate, which in turn drives the first sprocket to rotate. The first sprocket then drives the turntable to rotate, causing the turntable to repeatedly slide and adjust the second limiting rod within the second limiting groove. This causes the second limiting rod to repeatedly move the fixed plate laterally, which in turn causes the fixed plate to repeatedly slide the rack laterally on the surface of the first limiting rod, thus driving the rack to repeatedly move with its meshing mechanism. The transmission gear one rotates repeatedly, causing the shaft one to rotate, which in turn causes the bevel gear two to rotate repeatedly, which in turn causes the bevel gear one meshing with it to rotate repeatedly, which in turn causes the lead screw to rotate repeatedly, causing the lead screw to drive the piston threaded to slide repeatedly on the surface of the sliding rod. When flushing is required, the piston is moved by controlling the motor, which pushes the water in the storage tank downwards, resulting in a greater impact force of the water flow. This allows for flushing with only a small amount of water and a better flushing effect. 2. The motor drives the second shaft to rotate. Under the action of two meshing transmission gears, the second shaft, the crusher, and the transmission gears rotate synchronously in opposite directions. This causes the second shaft to drive the crusher to rotate in the opposite direction, enabling the crusher to crush objects and avoid clogging the pipes. The protective covers I and II reduce noise between the transmission components, making the noise level lower. Attached Figure Description

[0021] Please see Figures 1-5 As shown, a water-saving toilet with a low-noise flushing structure includes a main body 1. A water storage tank 2 is fixed to one side of the main body 1. The water storage tank 2 is used to store water for flushing excrement. A sliding rod 4 is fixed to the inner side of the water storage tank 2, and a piston 5 slides on the outer side of the sliding rod 4. The sliding of the piston 5 can squeeze the water in the water storage tank 2, making the water flow more impactful. A lead screw 7 rotates inside the water storage tank 2, and a bevel gear 8 is fixed to the outer side of the lead screw 7. A rotating shaft 9 rotates on one side of the water storage tank 2. A bevel gear 10 is fixed to one end of the rotating shaft 9, and a transmission gear 11 is fixed to the other end of the rotating shaft 9. A limit rod 12 is fixed to one side of the water storage tank 2, and a toothed gear slides on the outer side of the limit rod 12. A rack 13 has a fixed plate 15 on one side, a bracket 17 on one side of the water tank 2, a turntable 18 rotating on one side of the bracket 17, a limit rod 19 rotating on one side of the turntable 18, a sprocket 20 fixed on one side of the turntable 18, a sewage tank 21 inside the main body 1 for treating excrement, a rotating shaft 24 rotating inside the sewage tank 21, a crusher 25 fixed on the outside of the rotating shaft 24, the crusher 25 crushes excrement or other objects to avoid clogging the sewage pipe 23, a transmission gear 26 fixed at one end of the rotating shaft 24, a sprocket 27 fixed at one end of the rotating shaft 24, and a motor 29 fixed on one side of the main body 1. Example 2
[0022] Please see Figures 1-5As shown, a water inlet 3 is fixedly connected to one side of the water storage tank 2, and the water inlet 3 connects to the interior of the water storage tank 2. Four rectangular sliding rods 4 are arranged. A sealing ring 6 is fixed to the outside of the piston 5, and the sealing ring 6 fits tightly against the inner wall of the water storage tank 2, ensuring that the piston 5 maintains a tight fit against the inner wall of the water storage tank 2 when moving, thus improving the squeezing effect of the piston 5 on the water. A lead screw 7 is threadedly connected to the piston 5, and the lead screw 7 rotates synchronously with the first bevel gear 8. The first bevel gear 8 meshes with the second bevel gear 10. A rotating shaft 9 rotates synchronously with the second bevel gear 10, and the lead screw 7 rotates synchronously with the rotating shaft 9. One end of the rotating shaft 9 extends to the outside of the water storage tank 2. A transmission gear 11 is fixedly installed on... At the end of the rotating shaft 9 furthest from the bevel gear 10, a limiting groove 14 is provided on one side of the rack 13. The limiting rod 12 is slidably connected to the limiting groove 14. The rack 13 meshes with the transmission gear 11. A limiting groove 16 is provided on one side of the fixed plate 15. The limiting rod 19 is slidably connected to the limiting groove 16. The turntable 18 and the sprocket 20 rotate synchronously. The sprocket 20 drives the turntable 18 to rotate, so that the turntable 18 can drive the limiting rod 19 to slide repeatedly within the limiting groove 16. This allows the limiting rod 19 to slide repeatedly laterally on the fixed plate 15, and the fixed plate 15 to move the rack 13 laterally on the surface of the limiting rod 12. Example 3
[0023] Please see Figures 1-5 As shown, a sewage inlet pipe 22 is connected to one side of the sewage tank 21, and a sewage outlet pipe 23 is connected to the other side. Two rotating shafts 24, two crushing blades 25, and two transmission gears 26 are each provided. The two transmission gears 26 mesh with each other. One end of the rotating shaft 24 extends to the outside of the main body 1. A chain 28 meshes between a second sprocket 27 and a first sprocket 20. The output end of the motor 29 is fixed to one end of one rotating shaft 24. The motor 29 drives the rotating shaft 24 to rotate. Under the action of the two meshing transmission gears 26, the two rotating shafts 24 rotate synchronously in opposite directions. The rotating shaft 24 can drive the crushing blade 25 to rotate, thus... The rotation of the crusher blade 25 can crush the flushed excrement or other objects, preventing blockage of the sewage pipe 23. This allows the rotating shaft 24 to drive the sprocket 27 to rotate, which in turn drives the sprocket 20 to rotate under the action of the chain 28. A protective cover 30 is fixedly installed on one side of the main body 1, located on the side of the motor 29. A protective cover 31 is fixedly installed on one side of the main body 1, located outside the two transmission gears 26. A control panel 32 is fixedly installed on one side of the main body 1, electrically connected to the motor 29. The operation of the motor 29 can be controlled through the control panel 32.
[0024] In use, when flushing is required, the control panel 32 controls the motor 29 to rotate, causing the motor 29 to drive the second shaft 24 to rotate. Under the action of two meshing transmission gears 26, the two shafts 24 rotate synchronously in opposite directions, causing the shafts 24 to drive the sprocket 27 to rotate. The sprocket 27, under the action of the chain 28, drives the first sprocket 20 to rotate, causing the first sprocket 20 to rotate. The first sprocket 20 then drives the turntable 18 to rotate, causing the turntable 18 to drive the second limiting rod 19 to slide repeatedly within the second limiting groove 16. The second limiting rod 19 then drives the fixing plate 15 to slide repeatedly laterally, causing the fixing plate 15 to drive the rack 13 to move repeatedly laterally on the surface of the first limiting rod 12. The rack 13 then drives the rack with the corresponding... The intermeshing transmission gear 11 rotates repeatedly, causing the transmission gear 11 to drive the rotating shaft 9 to rotate, which in turn drives the bevel gear 10 to rotate, which in turn drives the bevel gear 8 that meshes with it to rotate, which in turn drives the lead screw 7 to rotate, which in turn drives the piston 5, which is threaded to it, to slide and adjust on the surface of the sliding rod 4. When the piston 5 moves downward, it squeezes the water in the water tank 2, making the water flow more impactful, thus requiring less water to complete the flushing and achieving a better flushing effect. At the same time, the rotating shaft 24 drives the crusher 25 to rotate, which crushes the flushed excrement or other objects, preventing blockage of the drain pipe 23.
[0025] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
