Description

Technical Field

[0001] The utility model relates to the technical field of bathrooms, in particular to a pressure storage type flushing full-flat toilet. Background Art

[0002] In recent years, smart toilets have gained market recognition and favor. The enormous market potential has attracted numerous companies within the industry, even leading to cross-industry expansion, transforming the traditional design of toilets. The design concept of the fully flush toilet has been particularly well-received and highly praised. However, the compact and sophisticated design of fully flush toilets places new demands on flushing functionality. Consequently, various flushing technologies have emerged, moving away from traditional high-level tank flushing methods. While the market currently favors fully flush tankless toilets, these current designs typically feature flushing equipment housed in hollow chambers on either side of the S-curve drain pipe at the rear of the toilet, leaving the top surface for the intelligent electrical control devices. The present utility model, in contrast, houses the pressure-storage flushing device in the cavity above the S-curve drain pipe, while the cavities on either side house the intelligent electrical devices and other functional devices. This design more effectively utilizes limited space, facilitates exterior design, and eases future maintenance. Utility Model Content

[0003] The purpose of the utility model is to provide a pressure storage type flushing full-flat toilet to solve the above problems.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A pressure storage flushing full-flat toilet comprises a toilet body and a pressure storage flushing device. A mounting groove is provided at the rear end of the toilet body and above the S-bend sewage pipe, and the pressure storage flushing device lies horizontally in the mounting groove.

[0006] Preferably, the pressure storage flushing device includes a water tank, a pressure storage component, a water inlet control component and a drainage control component. The pressure storage component is arranged in the water storage cavity of the water tank, and water is quantitatively stored in the water storage cavity through the pressure storage component to maintain the water inlet pressure when the water tank is filled with water, and the drainage pressure when the water tank is drained comes from the pressure storage component. The water inlet control component is arranged at the water inlet end of the water tank to adjust and set the water inlet pressure, and the drainage control component is arranged at the drainage end of the water tank to adjust and set the drainage time and flow.

[0007] Preferably, the water inlet control assembly includes a one-way valve, a pressure-stabilizing valve and an anti-siphon valve connected in series. The one-way valve is used to prevent the water in the water storage tank from flowing back into the water inlet pipe. The pressure-stabilizing valve is used to control the maximum water pressure in the water storage tank. The anti-siphon valve is used to introduce atmosphere when negative pressure is generated in the water inlet pipe and cooperates with the one-way valve to prevent the water in the water storage tank from flowing back.

[0008] Preferably, the drainage control component includes an air-controlled pilot valve and an air pressure generator. The air-controlled pilot valve is used to adjust the drainage time and flow rate of the drainage pipe, and the air pressure generator is used to drive the air-controlled pilot valve to open drainage.

[0009] Preferably, the drainage end is connected to the toilet flushing nozzle and the toilet bottom hole nozzle through a first hose and a second hose respectively.

[0010] Preferably, the pressure storage assembly includes a piston, a pressure storage spring and a guide rod. The guide rod is axially arranged in the water storage chamber. A guide sleeve is provided at the center of the piston. The piston slides on the outside of the guide rod through the guide sleeve, and the piston divides the water storage chamber into two upper and lower cavities that do not flow into each other. The pressure storage spring is axially placed in the water storage tank and its two ends are pressed against the inner wall of the water storage chamber and the piston respectively.

[0011] Preferably, a water outlet is provided at the bottom end of the water storage tank and a three-way joint is provided on the water outlet, the other two end joints of the three-way joint are respectively the water inlet interface and the drainage end interface of the water storage tank, and a filter net is provided between the piston and the three-way joint to filter the water entering the water storage chamber.

[0012] After adopting the above technical solution, the utility model has the following advantages compared with the background technology:

[0013] 1. The utility model provides a pressure storage flushing full-flush toilet. The pressure storage device is horizontally arranged in a narrow installation groove at the rear end of the full-flush toilet. With ultra-low water pressure (0.03Mpa) and only about 3 liters of water, the toilet is flushed to meet the dirt standards, solving the pain points of the flushing device of the full-flush tankless toilet.

[0014] 2. The utility model provides a pressure storage type flushing full-flat toilet, which stores the water pressure when the water tank is filled with water through the pressure storage component. The drainage pressure when the water tank is drained comes from the pressure storage component. The drainage water pressure and flow are set by the preset pressure release of the pressure storage component and the water storage amount in the water tank, solving the problems of unstable water pressure and small flow in the water supply network, so that the toilet can meet the flushing needs.

[0015] 3. The utility model provides a pressure storage type flushing full-flat toilet. When water enters the water tank, the water pressure pushes the piston to rise along the guide rod. Since the guide sleeve of the piston is provided with a water seal ring, the sealing performance of the contact position between the guide sleeve and the guide rod is ensured, preventing the water flow at the front end of the water tank from entering the rear end of the water tank through the guide sleeve.

[0016] 4. The utility model provides a pressure storage type flushing full-flat toilet. The pressure storage spring adopts a conical coil spring to store pressure to prevent the pressure storage spring from tilting left and right and deforming during the compression process. The compressed pressure storage spring is stored in the piston cavity at the end of the piston. Under the fixed water tank volume, the water storage capacity of the water storage cavity is increased, thereby increasing the flushing pressure.

[0017] 5. The present invention provides a pressure storage type flush toilet. A three-way joint is provided on the water inlet of the water storage tank, and the other two ends of the three-way joint are respectively provided as the water inlet and outlet interfaces of the water storage tank. A filter screen is provided between the piston and the water inlet to filter the water entering the water storage tank. When water enters the water inlet, particles in the water are blocked by the filter screen on the membrane, preventing the particles from entering the pressure storage component, affecting the operation of the pressure storage component, and accelerating the wear of the piston and the cylinder wall. When the outlet is opened for drainage, the water in the water storage tank is discharged through the water inlet by the thrust of the pressure storage spring. At this time, the impurities intercepted by the filter screen leave the filter screen under the push of the water flow and are discharged through the outlet end of the three-way joint.

[0018] 6. The utility model provides a pressure storage type flushing full-flat toilet. When the water tank is filled with water and the piston moves to the end position of the stroke, the first sealing ring and the second sealing ring on the top surface of the piston are in close contact with the first annular boss and the second annular boss on the inner wall of the water storage chamber respectively. At the same time, the third sealing ring inlaid on the outer wall of the piston is in close contact with the inner wall of the water storage chamber, thereby comprehensively improving the sealing performance of the piston and preventing water at the front end of the water storage chamber from entering the rear end during the piston's force storage activity.

[0019] 7. The utility model provides a pressure storage flushing full-flat toilet. The piston is axially slidable in the water storage chamber through a guide rod, which limits the moving direction of the piston and prevents the piston from deflecting.

[0020] 8. The utility model provides a pressure storage type flushing full-flat toilet. The water inlet control component adjusts the water inlet pressure of the water inlet end of the water tank to ensure that the water inlet pressure is within a limited value, prevents the water tank from bursting, and prevents the water from flowing back; the drainage control component adjusts the drainage time and flow rate of the drainage end of the water tank, and connects the toilet flushing nozzle and the toilet bottom hole nozzle respectively through a first hose and a second hose to realize drainage diversion and communication to meet flushing needs.

[0021] 9. The utility model provides a pressure storage type flushing full-flat toilet. A first through hole connected to the water storage chamber is opened at the top of the water tank. When the water tank is horizontally arranged at the rear end of the toilet, the position of the first through hole is located on the lower tank wall. It can be used as an exhaust function to discharge the gas at the rear end of the water tank when the water inlet piston of the water tank moves backward. It can also be used as a drainage function to discharge the water leaked to the rear end of the water tank from this hole into the toilet bowl for flushing when the sealing structure of the piston leaks.

[0029] Example

[0030] Please refer to Figures 1 to 5 As shown, the utility model discloses a pressure storage flushing full-flat toilet, which includes a toilet body and a pressure storage flushing device. A mounting groove is provided at the rear end of the toilet body and above the S-bend sewage pipe, and the pressure storage flushing device lies horizontally in the mounting groove.

[0031] The pressure storage flushing device includes a water tank 1, a pressure storage component 2, a water inlet control component 3 and a drainage control component 4. The water tank 1 lies horizontally above the S-bend sewage pipe at the rear end of the toilet body. The pressure storage component 2 is arranged in the water storage chamber 11 of the water tank 1 to store the water inlet pressure when the water tank 1 is filled with water. The drainage pressure when the water tank 1 is drained is the water inlet pressure stored by the pressure storage component 2. The water inlet control component 3 is arranged at the water inlet end of the water tank 1 to adjust the water inlet pressure. The drainage control component 4 is arranged at the drainage end of the water tank 1 to adjust the drainage time and flow.

[0032] The pressure storage assembly 2 includes a piston 21, a pressure storage spring 22, and a guide rod 23. The guide rod 23 is axially disposed within the water storage chamber 11. A sliding hole 215 extending vertically through the center of the piston 21 is formed. A guide sleeve is disposed within the sliding hole 215. The piston 21 slides up and down along the guide sleeve, which is sleeved on the outside of the guide rod 23. During this sliding process, the outer wall of the piston 21 tightly mates with the inner wall of the water storage chamber 11. The inner wall of the guide sleeve of the piston 21 tightly mates with the outer wall of the guide rod 23. The piston 21 divides the water storage chamber 11 into two upper and lower chambers that are not in fluid communication with each other. The pressure storage spring 22 is axially disposed within the water storage chamber 11, with its ends pressing against the inner wall of the water storage chamber 11 and the piston 21, respectively. When the piston 21 reaches its stop position, the pressure storage spring 22 is subjected to a predetermined flushing pressure. The water level within the water storage tank 1 determines the flushing volume. In this embodiment, the water storage tank 1 is configured to hold 3 liters of water.

[0033] The bottom end of the water storage tank 1 is provided with a water inlet 12 connected to the water storage chamber 11. A three-way joint 5 is provided on the water inlet 12, and the other two end joints of the three-way joint 5 are respectively the water inlet interface and the drainage interface of the water storage tank 1. A filter screen 6 is provided in the water storage chamber 11 and between the piston 21 and the water inlet 12. When water enters the water inlet end, impurities in the water are blocked on the mesh by the filter screen 6, preventing impurities from entering the pressure storage component 2, grinding the piston 21 and the inner wall of the water storage chamber 11, affecting the operation of the piston 21, and improving the service life of the pressure storage component 2. When the drainage end is opened for drainage, the water in the water storage tank 1 is discharged through the water inlet 12 by the thrust of the pressure storage spring 22. At this time, the impurities intercepted on the filter screen 6 leave the filter screen 6 under the push of the water flow and are discharged through the drainage end of the three-way joint 5.

[0034] The pressure-storage spring 22 is a conical coil spring. The piston 21 has a trapezoidal shape. A piston cavity 211 is defined at the top of the piston 21, and the bottom of the pressure-storage spring 22 is connected to the bottom of the piston cavity 211. The piston 21 is axially slidable within the water storage chamber 11 via a guide rod 23, which limits the movement of the piston 21 and prevents it from shifting. The pressure-storage spring 22 is a conical coil spring for storing pressure, preventing it from tilting or deforming during compression. The compressed pressure-storage spring 22 is housed in the piston cavity 211 at the end of the piston 21. Given a fixed volume of the water tank 1, the water storage capacity of the water storage chamber 11 is increased, thereby increasing the flushing pressure.

[0035] The top of the water tank 1 is provided with a first through-hole 13 that communicates with the water storage chamber 11. When the water tank 1 is positioned horizontally at the rear end of the toilet, the first through-hole 13 is located on the lower tank wall. This through-hole 13 serves as a vent to expel air from the rear end of the water tank 1 when the water inlet piston 21 of the water tank 1 moves backward. It also serves as a drainage system to drain water from the rear end of the water tank 1 into the toilet bowl if the sealing structure of the piston 21 leaks.

[0036] An upper sealing ring and a side sealing ring are respectively provided on the top surface and the side surface of the skirt of the piston 21 . The upper sealing ring includes a first sealing ring 212 and a second sealing ring 213 , and the side sealing ring includes a third sealing ring 214 .

[0037] A first sealing ring 212 and a second sealing ring 213 are respectively inlaid on the top surface of the piston 21's skirt, located inside and outside the opening of the piston chamber 211. A first annular boss 14 and a second annular boss 15 are respectively provided on the inner wall of the water storage chamber 11, located below the first through-hole 13, to closely engage with the first and second sealing rings 212 and 213. A third sealing ring 214 is inlaid on the outer wall of the piston 21's skirt, to closely engage with the inner wall of the water storage chamber 11. This comprehensively improves the sealing performance of the piston 21, preventing water from entering the rear end of the water storage chamber 11 during the piston 21's power accumulation activity.

[0038] The guide sleeve includes an upper guide sleeve 216 and a lower guide sleeve 217. An upper inlay groove and a lower inlay groove are respectively provided in the top opening and the bottom opening of the sliding hole 215. The upper guide sleeve 216 is inlaid in the upper inlay groove, and the lower guide sleeve 217 is inlaid in the lower inlay groove. The inner walls of the upper guide sleeve 216 and the lower guide sleeve 217 are in close contact with the outer wall of the guide rod 23. A water seal ring 218 and a sealing ring fixing sleeve 219 are inlaid in the lower inlay groove 2152 and below the lower guide sleeve 217 from top to bottom. A V-shaped groove 2181 is provided on the bottom surface of the water seal ring 218, and the V-shaped opening direction of the V-shaped groove 2181 is toward the sealing ring fixing sleeve 219. The sealing ring fixing sleeve is used to prevent the water sealing ring from falling out of the lower embedding groove. When water enters the water tank 1, the water pressure pushes the piston 21 to rise. During the rising process of the piston 21, the sealing ring fixing sleeve 219 is pushed upward, thereby pushing the V-shaped opening 2181 to expand, so that the water sealing ring 218 is in close contact with the rod wall of the guide rod 23, ensuring the sealing performance of the contact position between the sliding hole 215 and the guide rod 23, and preventing the water flow at the front end of the water tank 1 from entering the rear end of the water tank 1 through the sliding hole 215.

[0039] A baffle 231 is fixed to one end of the guide rod 23 . The guide rod 23 passes through the water tank 1 and the other end thereof is threadedly connected to a locking nut 232 , so that the guide rod 23 is detachably mounted on the water tank 1 .

[0040] The bottom of the water tank 1 is provided with a second through-hole 16, which communicates with the water storage chamber 11. A valve is installed on this second through-hole 16. When the water tank 1 is positioned horizontally at the rear end of the toilet, the second through-hole 16 is located on the upper tank wall. When water enters the water tank 1, the valve opens, allowing air at the front end of the water tank 1 to escape through the second through-hole 16, preventing air pressure from hindering water inflow. The filter screen 6 is an isosceles trapezoidal structure, with water inlets 12 located on either side of the isosceles trapezoidal shape.

[0041] The water inlet end of the water storage tank 1 is connected to the water inlet pipe 17. The water inlet control component 3 includes a one-way valve 31, a pressure-stabilizing valve 32 and an anti-siphon valve 33 arranged in series on the water inlet pipe 17. The one-way valve 31 is used to prevent the water in the water storage tank 1 from flowing back into the water inlet pipe 17. The pressure-stabilizing valve 32 is used to adjust the water pressure in the water storage tank 1. The anti-siphon valve 33 is used to introduce atmosphere when negative pressure is generated in the water inlet pipe 17, and cooperates with the one-way valve 31 to prevent the water in the water storage tank 1 from flowing back.

[0042] The one-way valve 31 closes when the external water pressure is lower than the pressure within the water storage chamber 11, preventing the backflow of water within the water storage chamber 11. When the external water pressure is too high, the pressure-stabilizing valve 32 limits the water pressure at the water inlet to within the set pressure range of the water storage tank 1. This maintains the stability of the water pressure within the water storage tank 1, unaffected by changes in the external water pressure, and ensures that the water storage tank 1 operates under a safe water pressure. The anti-siphon valve 33 opens the air gap valve when the water inlet pipe loses pressure. It automatically switches between the closed and vented states of the valve body without external force, ensuring the anti-siphon effect.

[0043] The drain end of the water storage tank 1 is connected to a drain pipe 18. The drain control assembly 4 includes an air-controlled pilot valve 41 and an air pressure generator 42. The air-controlled pilot valve 41 utilizes a pneumatically controlled multifunctional pilot valve, as specified in Chinese Patent Publication No. CN 214838778 U. The air-controlled pilot valve 41 is installed in the drain pipe 18 and is driven by an air pressure generator to control the drain time and flow rate. The air pressure generator 42 utilizes a combination of manual and electric drive modes, such as an electric pump and a pressure pump. A manual drive switch is located on the side wall of the toilet body.

[0044] The drainage end of the drainage pipe 18 is connected to the toilet flushing nozzle 193 and the toilet bottom hole nozzle 194 through the first hose 191 and the second hose 192 respectively, realizing drainage diversion and connection to meet the flushing needs.

[0045] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
