Description

Technical Field

[0001] This utility model relates to the field of sanitary equipment technology, specifically to a novel water-saving and odor-proof toilet based on fluid dynamic pressure self-drive. Background Technology

[0002] Currently, toilets on the market are mainly divided into sit-down toilets and squat toilets. Sit-down toilets are also called toilets. The most widely used type of toilet is the siphon toilet. Siphon toilets and squat toilets use the siphon principle to flush and generally use a water trap to prevent odors. The water in the flush tank needs to replace the sewage in the toilet and the water trap to complete a flush. In order to achieve complete replacement, there must be sufficient water volume and water pressure.

[0003] Chinese invention patent 201110039774.1 discloses a smart toilet, including a toilet body with a flushing pipe controlled by a solenoid valve. A monitoring sensor is also installed on the toilet body, with its signal output connected to the input of a microcontroller. The output control terminal of the microcontroller is connected to the controlled terminal of the solenoid valve via a drive circuit. This utility model toilet can be used in both household and public restrooms. It can automatically flush the toilet in a timely manner according to its usage status via a solenoid valve. Compared to traditional toilets, it not only saves water and electricity but also effectively prevents the impact of untimely flushing on the ambient air, thus possessing significant practical value.

[0004] However, the aforementioned technologies have some drawbacks, such as: existing toilets generally rely heavily on circuit control during use, resulting in a high failure rate and a tendency to accidentally activate them; power outages also affect the usability of the toilets; the large amount of water stored in the trap is not water-saving enough; and the odor prevention effect is not good enough. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a novel water-saving and odor-proof toilet based on fluid dynamic pressure self-drive, which can solve the problems mentioned in the background technology.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0012] A water inlet valve assembly, wherein the water inlet valve assembly is disposed in the first water tank through a water inlet hole;

[0013] A valve assembly, comprising a jet injector, a water pipe connector, and a water flow valve, wherein the jet injector is detachably connected to the bottom inlet of the water supply valve assembly, and the water flow valve is fitted onto the end of the drain outlet.

[0014] Preferably, the toilet body has a first tank cover that matches the first water tank at the top opening, the first tank cover has a button hole at the top, the toilet button is installed in the button hole of the first tank cover, and the toilet seat is provided at the top of the horizontal section of the toilet body.

[0015] Preferably, the second water tank has a first limiting hole on its side wall and a second limiting hole on its bottom wall. The water inlet valve is located between the first limiting hole and the second limiting hole. Sealing gaskets are provided on both the inner and outer sides of the first limiting hole, and a first sealing ring is provided on the inner wall of the second limiting hole.

[0016] Preferably, the inlet valve includes a valve body and an overflow connector. The valve body and the overflow connector are detachably connected. A first steel shaft is slidably installed in the center hole of the overflow connector. A rubber sheet is installed on one end of the first steel shaft via a snap ring. A first liner and a second liner are respectively provided at the top and bottom ends of the rubber sheet. A first spring is provided between the second liner and the overflow connector. A first sealing plate is provided between the valve body and the overflow connector. A water valve connector is threaded to the horizontal section port of the inlet valve.

[0017] Preferably, the water flow valve includes a housing, one end of which is provided with a rubber sleeve that matches the drain outlet. A shaft cover is provided on the inner wall of the housing, and a rotating shaft is mounted on the housing via the shaft cover. A flap is rotatably mounted on the inner wall of the housing via the rotating shaft. A hydraulic cylinder is detachably connected through the side wall of the housing. A second steel shaft is slidably mounted on the inner wall of the hydraulic cylinder. A metal block is interference-fitted to the inner wall of the hydraulic cylinder. A second spring is provided between the top of the metal block and the top of the second steel shaft. A top block is rigidly connected to the bottom end of the second steel shaft. A threaded joint is provided on the top of the hydraulic cylinder. A second sealing plate is provided at the end of the housing away from the rubber sleeve.

[0018] Preferably, a second sealing ring is provided at one end of the flap near the rubber sleeve, and the flap forms a seal with the contact surface of the housing through the second sealing ring.

[0019] Preferably, the top of the second steel shaft is wrapped with a sealing ring to form a seal with the inner wall of the hydraulic cylinder.

[0020] Preferably, a first water pipe is used to connect a water valve connector and a water inlet valve assembly.

[0021] Preferably, a second water pipe is used to connect the jet injector and the threaded joint.

[0022] The beneficial effects of this utility model are as follows:

[0023] 1. By setting up a valve assembly, when tap water flows from port 6c to port 6d of the jet injector, the water flow valve is open, and ports 6a and 6b of the water flow valve are connected. When the tap water stops flowing, the water flow valve is closed, and ports 6a and 6b of the water flow valve are not connected. When tap water flows from port 6c to port 6d of the jet injector, the rapid flow of water through the jet injector creates a negative pressure in the second water pipe. The top of the hydraulic cylinder connected to it is sucked upward, and the spring in the hydraulic cylinder is also pushed upward. The steel shaft drives the top block to move upward, and the flap can be flipped clockwise to open. When the tap water flowing from port 6c to port 6d of the jet injector stops, the pressure of the tap water will reach the top of the hydraulic cylinder through the second water pipe, pressing the steel shaft downward. The spring in the hydraulic cylinder is compressed, and the steel shaft drives the top block to move downward. The flap closes counterclockwise.

[0024] The beneficial effects are: no circuit is needed to control the valve; the water flow valve can be mechanically controlled solely by the water flow state. The valve assembly can be used not only in toilets but also in kitchen drainage and odor prevention, bathroom floor drains, and other scenarios. The water flow valve opens to drain water when the faucet is turned on and closes to prevent odor when the faucet is turned off. The design has a wide range of applications and features a purely mechanical odor-proof valve structure suitable for multiple scenarios, greatly reducing the failure rate.

[0025] 2. By setting up a drain valve assembly and toilet body, when the water in the first water tank is sufficient to float the float ball in the first water tank's inlet valve assembly, the tap water inlet stops. At this time, the tap water flowing from port 6c to port 6d of the jet injector stops, and the pressure of the tap water will reach the top of the hydraulic cylinder through the second water pipe, pressing the second steel shaft downward. The second spring in the hydraulic cylinder is compressed, and the second steel shaft drives the top block to move downward, closing the flap counterclockwise. The flap in the water flow valve cannot be opened due to water pressure. At the same time, the rubber sheet of the inlet valve in the second water tank moves upward under the action of the first spring because it loses the pressure of the tap water. The water in the second water tank flows through the outlet and overflow outlet, and finally reaches the bottom of the toilet body through the overflow pipe in the drain valve assembly. Some water is stored at the bottom of the toilet body, and the final result is that all the water in the second water tank reaches the bottom of the toilet body.

[0026] The beneficial effects are: eliminating the water trap, reducing the need for a large amount of water to create a siphon effect, and reducing toilet water consumption. Attached Figure Description

[0043] Example 1:

[0044] Reference Figures 1-10 This utility model discloses a novel water-saving and odor-proof toilet based on fluid dynamic pressure self-drive, comprising: a toilet body 1, a first water tank 13 disposed on the top of the toilet body 1, a first tank cover 11 matching the first water tank 13 disposed on the top opening of the toilet body 1, a button hole 12 disposed on the top of the first tank cover 11, a toilet button 2 installed in the button hole 12 of the first tank cover 11, a drain hole 14 disposed on the bottom wall of the first water tank 13, a toilet seat 15 disposed on the top of the horizontal section of the toilet body 1, a water inlet hole 16 disposed on the bottom wall of the first water tank 13, a sewage outlet 17 disposed on the bottom of the toilet body 1, and a toilet button 2 located on the top of the toilet body 1.

[0045] Water tank assembly 3 includes a second water tank 31 located inside the first water tank 13. An inlet valve 32 is installed inside the second water tank 31, with an inlet 32a, an outlet 32b, and an overflow outlet 32c arranged sequentially from top to bottom. A first limiting hole 31a is provided on the side wall of the second water tank 31, and a second limiting hole 31b is provided on the bottom wall. The inlet valve 32 is located between the first limiting hole 31a and the second limiting hole 31b. Sealing gaskets 34 are provided on both the inner and outer sides of the first limiting hole 31a, and a first sealing ring 35 is provided on the inner wall of the second limiting hole 31b. The inlet valve 32 includes a valve body 321 and an overflow connector 329, which are detachably connected. The center of the overflow connector 329... A first steel shaft 326 is slidably installed inside the hole. A rubber sheet 324 is installed on one end of the first steel shaft 326 via a snap ring 322. A first liner 323 and a second liner 325 are respectively provided at the top and bottom of the rubber sheet 324. A first spring 327 is provided between the second liner 325 and the overflow connector 329. A first sealing plate 328 is provided between the valve body 321 and the overflow connector 329. A water valve connector 33 is threadedly connected to the horizontal section port of the inlet valve 32. A drain valve assembly 4 is installed in the first water tank 13 through a drain hole 14. The drain valve assembly 4 includes an overflow pipe 9, which matches the bottom of the toilet body 1. A water inlet valve assembly 5 is installed in the first water tank 13 through a water inlet hole 16.

[0046] The second limiting hole 31b at the bottom of the second water tank 31 is a stepped hole that extends below the bottom surface of the second water tank 31, allowing the water in the second water tank 31 to drain as cleanly as possible and preventing water from accumulating for a long time. The second limiting hole 31b is connected to the overflow pipe 9 in the first water tank 13.

[0047] exist Figure 6In the indicated state, the outlet 32b and the inlet 32a are connected. If tap water flows in from the inlet 32a, the first steel shaft 326 will compress the first spring 327 and move downward under the action of water pressure. The rubber sheet 324 will press against the upper end of the overflow connector 329, and the overflow outlet 32c will not discharge water. The water will flow out through the outlet 32b.

[0048] Valve assembly 6 includes a jet injector 61, a water pipe connector 62, and a water flow valve 63. The jet injector 61 is detachably connected to the bottom inlet of the water supply valve assembly 5. The water flow valve 63 is fitted onto the end of the drain outlet 17. The water flow valve 63 includes a housing 631, with a rubber sleeve 632 at one end that matches the drain outlet 17. A shaft cover 6313 is provided on the inner wall of the housing 631. A rotating shaft 633 is installed on the housing 631 via the shaft cover 6313. A flap 634 is rotatably mounted on the inner wall of the housing 631 via the rotating shaft 633. A second sealing ring 635 is provided on the end of the flap 634 near the rubber sleeve 632. The flap 634 forms a seal with the housing 631 through the second sealing ring 635. The side wall of the housing 631 is through-walled and A hydraulic cylinder 637 is detachably connected. A second steel shaft 6311 is slidably mounted on the inner wall of the hydraulic cylinder 637. A sealing ring 638 is wrapped around the top of the second steel shaft 6311, forming a seal with the inner wall of the hydraulic cylinder 637. A metal block 6310 is interference-fitted to the inner wall of the hydraulic cylinder 637. A second spring 639 is provided between the top of the metal block 6310 and the top of the second steel shaft 6311. A top block 6312 is rigidly connected to the bottom of the second steel shaft 6311. A threaded joint 636 is provided on the top of the hydraulic cylinder 637. A second sealing plate 6314 is provided at the end of the housing 631 away from the rubber sleeve 632. A first water pipe 7 is used to connect the water valve joint 33 and the water inlet valve assembly 5. A second water pipe 8 is used to connect the jet injector 61 and the threaded joint 636.

[0049] When tap water flows from port 6c to port 6d of the jet injector 61, the water flow valve 63 is open, and ports 6a and 6b are connected. When the tap water stops flowing, the water flow valve 63 is closed, and ports 6a and 6b are not connected.

[0050] When tap water flows from port 6c to port 6d of the jet injector 61, the rapid flow creates a negative pressure in the second water pipe 8. This causes the top of the connected hydraulic cylinder 637 to be drawn upwards, and the spring 639 within the cylinder also pushes upwards. The steel shaft 6311 drives the top block 6312 upwards, allowing the flap 634 to open clockwise. When the flow of tap water from port 6c to port 6d of the jet injector 61 stops, the pressure of the tap water passes through the second water pipe 8 and reaches the top of the hydraulic cylinder 637, pressing the steel shaft 6311 downwards. This compresses the spring 639 in the cylinder, causing the top block 6312 to move downwards, and the flap 634 to close counterclockwise.

[0051] Example 2:

[0052] In Embodiment 2, the same symbols are used for the same structures as in Embodiment 1, and common descriptions are omitted.

[0053] Reference Figure 11 A novel water-saving and odor-proof toilet based on hydrodynamic pressure self-drive is different from Embodiment 1 in that the toilet body 1 is replaced by a squat toilet instead of a toilet.

[0054] The working principle and usage process of this utility model are as follows: Tap water enters from the bottom of the jet injector 61, passes through the jet injector 61, enters through the water inlet valve assembly 5, and then enters the second water tank 31 through the first water pipe 7. The rubber sheet 324 of the inlet valve 32 in the second water tank 31 moves down due to the pressure of the tap water, and the overflow port 32c of the inlet valve 32 is sealed. Tap water comes out from the outlet 32b of the second water tank 31, and water accumulates in the second water tank 31 until it overflows the second water tank 31. The water in the second water tank 31 overflows into the first water tank 13 of the toilet body 1.

[0055] At the same time, the tap water passes through the jet injector 61, which creates a negative pressure in the second water pipe 8. The top of the hydraulic cylinder 637 connected to it is sucked upward, and the second spring 639 in the hydraulic cylinder 637 is also pushed upward. The second steel shaft 6311 drives the top block 6312 to move upward, and the flap 634 in the water flow valve 63 flips clockwise to open due to the pressure difference.

[0056] When the water in the first water tank 13 is sufficient to float the float ball in the water valve assembly 5 of the first water tank 13, the tap water inlet stops. At this time, the tap water flowing from port 6c to port 6d of the jet injector 61 stops. The pressure of the tap water will reach the top of the hydraulic cylinder 637 through the second water pipe 8, pressing the second steel shaft 6311 downward. The second spring 639 in the hydraulic cylinder 637 is compressed. The second steel shaft 6311 drives the top block 6312 to move downward. The flap 634 closes counterclockwise. The flap 634 in the water flow valve 63 cannot be opened due to water pressure. At the same time, the rubber sheet 324 of the inlet valve 32 in the second water tank 31 moves upward under the action of the first spring 327 because it loses the pressure of the tap water. The water in the second water tank 31 flows through the outlet 32b and the overflow outlet 32c, and finally reaches the bottom of the toilet body 1 through the overflow pipe 9 in the drain valve assembly 4. Some water is stored at the bottom of the toilet body 1. The final result is that all the water in the second water tank 31 will reach the bottom of the toilet body 1.

[0057] When using the toilet, pressing toilet button 2 opens the drain valve assembly 4, releasing water from the first water tank 13 into the toilet to flush it. Simultaneously, the float in the inlet valve assembly 5 drops, and the second water tank 31 begins to fill with water. As mentioned earlier, while the toilet is filling with water, the water flow valve 63 opens, allowing wastewater to be discharged through the valve. The toilet continues to fill with water until the float in the inlet valve assembly 5 of the first water tank 13 floats up. As mentioned earlier, after the toilet stops filling with water, the water flow valve 63 closes. At this point, the water in the second water tank 31 reaches the bottom of the toilet body 1 through the overflow pipe 9 in the first water tank 13. The presence of some water at the bottom helps prevent odor from feces and also moistens the toilet wall, preventing waste from sticking to it.

[0058] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
