Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sanitary ware and relates to toilet flushing structure, specifically to a vortex flush toilet pressure structure. Background Technology
[0002] Toilets are common sanitary ware, usually made of ceramic. In a vortex flush toilet, the main flush hole is located on one side of the bowl. After the water flows out of the main flush hole, it forms a vortex along the inner wall of the bowl, increasing the flushing force against the inner wall. The water channels in modern vortex flush toilets have parallel upper and lower surfaces, and the flow area within the channels is the same as the outlet area of the main flush hole. Therefore, the water flow within the channels is relatively stable, and there is no significant change in water pressure after the water exits from the main flush hole.
[0003] Stubborn stains often accumulate on toilets, and flushing them using the existing water system can be ineffective, requiring multiple flushes to remove the stains and increasing water consumption. Increasing the flushing force with the same amount of water can improve the flushing effect and thus improve the toilet's water-saving performance. Utility Model Content
[0004] This invention addresses the technical problem of increasing water pressure in toilets to improve flushing efficiency and achieve water conservation by providing a vortex flush toilet pressure structure. By extending the waterway path, a variable-diameter composite pressure structure can be created, increasing the speed and pressure of the water flow. This ensures uniform and stable water output from the main flush hole, prevents water from scattering and splashing, improves the flushing effect, thoroughly flushes the toilet bowl, reduces water volume, and achieves water conservation.
[0005] The technical solution adopted by this utility model is: to provide a vortex flush toilet water pressure structure, including a water channel surrounding the outside of the toilet bowl, with both ends of the water channel connected to the toilet's water inlet and main flush hole respectively, characterized in that: the main flush hole is located on the left or right side of the toilet bowl, the water inlet is located on the opposite side of the main flush hole, and the water channel is a variable diameter composite water pressure structure.
[0006] The main flush hole is located on the left or right side of the toilet, while the water inlet is located on the opposite side of the main flush hole. This extends the water channel path, making it easier to process the shape of the water channel. By supporting it with a variable diameter composite water pressure structure, it can ensure that the water output from the main flush hole is uniform and stable, and prevent water flow from spreading and splashing, thereby improving the flushing effect of the toilet.
[0007] To further optimize this technical solution, the variable diameter composite pressure water structure of the waterway includes a primary variable diameter section and a secondary variable diameter section. The primary variable diameter section is connected to the inlet, and the secondary variable diameter section is connected to the main punch hole. Both the primary and secondary variable diameter sections include a pressure water section that converges the flow towards the outlet.
[0008] During flushing, water in the toilet tank flows into the waterway through the inlet. As the water flows along the first diameter-changing section, the pressure section on the first diameter-changing section accelerates and pressurizes the water flow. Then, it enters the second diameter-changing section, where the initial velocity of the water flow increases. When the water is sprayed into the toilet bowl through the main flushing hole to wash its surface, the pressure section on the second diameter-changing section further accelerates and pressurizes the water flow, increasing the flushing force of the water jet from the main flushing hole and improving the washing effect on the toilet bowl surface. This ensures a thorough flush, improves flushing efficiency, and the increased flushing force reduces the amount of water used, thus saving water.
[0009] To further optimize this technical solution, the flow area at the starting end of the primary diameter-changing section is 626 mm²-1460 mm².
[0010] To further optimize this technical solution, the flow area at the end of the primary diameter-changing section is 580 mm²-1354 mm², and the end of the primary diameter-changing section is connected to the beginning of the secondary diameter-changing section, and is smaller than the flow area at the beginning of the secondary diameter-changing section.
[0011] When the water flows into the secondary diameter change section, the flow area at the beginning of the secondary diameter change section is larger than that at the end of the primary diameter change section, which reduces the flow velocity and weakens the impact force of the water flow on the inner wall of the waterway, thereby reducing the generation of noise.
[0012] To further optimize this technical solution, the flow area at the starting end of the secondary diameter-changing section is 628 mm²-1466 mm², which is larger than the water outlet area of the main punch.
[0013] The water flows along the secondary diameter change section. The gradual contraction of the flow area in the secondary diameter change section increases the flow velocity of the water for the second time and has a water gathering and flow gathering effect. After the water flows into the toilet through the main flush hole, it has an anti-swirling effect, thereby preventing water splashing, improving flushing efficiency, and forming a vortex to enhance the cleaning effect on the toilet.
[0014] To further optimize this technical solution, the lower surface of the secondary diameter-changing section is flush with the lower surface of the primary diameter-changing section.
[0015] The lower surface of the waterway is flush with the ground to reduce water flow resistance, ensure smooth water flow, and prevent water splashing.
[0016] To further optimize this technical solution, a stepped surface is provided at the connection end between the secondary diameter-changing section and the primary diameter-changing section.
[0017] The stepped surface is designed to accommodate the changes in flow area between the primary and secondary diameter change sections.
[0018] To further optimize this technical solution, the upper surfaces of both the primary diameter-changing section and the secondary diameter-changing section are downwardly inclined slopes.
[0019] The lower surfaces of the secondary diameter-changing section are flush with those of the primary diameter-changing section. The inclined surface causes the flow area of the primary and secondary diameter-changing sections to gradually shrink, thereby achieving the effect of pressurizing the water flow.
[0020] To further optimize this technical solution, the inclined arc length of the upper surface of the primary diameter-changing section is 10 mm to 500 mm, and the inclined arc length of the secondary diameter-changing section is 20 mm to 386.16 mm.
[0021] The beneficial effects of this utility model are as follows:
[0022] 1. During flushing, after the water flows into the first diameter change section from the waterway, the pressure section on the first diameter change section reduces the flow area, causing the water flow to accelerate and pressurize once within the first diameter change section. This increases the initial velocity as the water flows into the second diameter change section, and the pressure section on the second diameter change section further accelerates and pressurizes the water flow. This increases the flushing force of the water jet from the main punch, improves the flushing effect on the surface of the toilet bowl, and ensures a thorough flush, thus improving flushing efficiency. Furthermore, the increased flushing force reduces the amount of water used, achieving water conservation.
[0023] 2. When the water flows from the primary diameter change section to the secondary diameter change section, the flow area at the beginning of the secondary diameter change section is larger than that at the end of the primary diameter change section. This reduces the flow velocity and the impact force of the water flow on the inner wall of the waterway, thereby reducing noise. Then, the water flows along the secondary diameter change section. The gradual contraction of the flow area in the secondary diameter change section makes the water flow more concentrated and increases the flow velocity. After being sprayed out of the main punch, the water output is uniform and stable, preventing swirling water and splashing, and improving the vortex formation effect in the toilet bowl, thus enhancing the cleaning effect of the toilet and improving flushing efficiency.
[0024] 3. The lower surface of the secondary diameter-changing section of the waterway is flush with the lower surface of the primary diameter-changing section, reducing water flow resistance. By setting downward sloping surfaces on the upper surfaces of the primary and secondary diameter-changing sections, the flow area of the primary and secondary diameter-changing sections gradually shrinks, increasing the water flow force and creating a water-gathering effect. This prevents water from splashing after being sprayed into the toilet bowl through the main flushing hole, ensuring a good flushing effect. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Example 1
[0032] Please see the appendix Figure 1-5 The vortex flush toilet's pressurized water structure includes a water channel 2 surrounding the toilet bowl 1. Both ends of the water channel 2 are connected to the toilet's inlet 3 and main flush hole 4, respectively. The main flush hole 4 is located on the left or right side of the toilet, while the inlet 3 is located on the opposite side of the main flush hole 4, thus extending the path of the water channel 2. This allows the water channel 2 to be made into a variable-diameter composite pressurized water structure, including a primary variable-diameter section 201 and a secondary variable-diameter section 202. The primary variable-diameter section 201 is connected to the inlet 3, and the secondary variable-diameter section 202 is connected to the main flush hole 4. Both the primary and secondary variable-diameter sections 201 and 202 include a pressurized section that converges the flow towards the outlet. After the water flows from the water channel 2 into the primary variable-diameter section 201, the water flow, upon entering the pressurized section, is affected by the increased flow area of the water channel 2. The contraction leads to an increase in water flow velocity and a stronger impact force, increasing the initial velocity of the water entering the secondary diameter change section 202. After passing through the pressure section of the secondary diameter change section 202, the water flow velocity is further increased, and the water is ejected from the main punch 4. According to the continuity equation and Bernoulli's equation, the increased velocity and kinetic energy result in a corresponding increase in impact force. This increased impact force enhances the flushing power on the toilet bowl 1 and ensures a thorough flush, guaranteeing a good flushing effect and improving flushing efficiency. Furthermore, the increased impact force reduces the amount of water used, achieving water conservation. The main punch 4 is located on one side of the toilet bowl 1, allowing the water to swirl and flow into the bowl, ensuring uniform water output and preventing water from scattering and splashing. Example 2
[0033] When water flows within the primary diameter-changing section 201, the flow area at its initial end is 626 mm²-1460 mm², and the flow area at its end is 580 mm²-1354 mm². Due to the contraction of the flow area within the primary diameter-changing section 201, the water flow speeds up and pressurizes. Upon entering the secondary diameter-changing section 202, the initial velocity of the water flow increases. The flow area at the initial end of the secondary diameter-changing section 202 is larger than the flow area at the end of the primary diameter-changing section 201, i.e., larger than the flow area at the junction of the two. The flow area at the initial end of the secondary diameter-changing section 202 is 628 mm²-1466 mm², and it is also larger than the outlet area of the main punch 4. The water flows within this range of flow areas, achieving a balance between the flow fluidity and the pressure-boosting effect, ensuring... To ensure a balance between water output and flushing effect, the increased flow area at the beginning of the secondary diameter-changing section 202, as the water flows from the end of the primary diameter-changing section 201 to the beginning of the secondary diameter-changing section 202, reduces the flow velocity to accommodate the larger flow area. This reduced velocity weakens the impact force on the inner wall of the waterway 2, thus reducing noise. The water then flows along the secondary diameter-changing section 202, undergoing secondary acceleration and pressurization before being sprayed into the toilet bowl 1 through the main flush hole 4. This ensures a good flushing effect and even water usage. According to experiments, 3L of water can be used to achieve a comprehensive flushing effect, resulting in water conservation. The main flush hole 4 increases the flow velocity of the water sprayed into the toilet bowl 1, improving flushing efficiency and creating a vortex to enhance the cleaning effect of the toilet. Example 3
[0034] The lower surfaces of the secondary diameter-changing section 202 of waterway 2 are flush with those of the primary diameter-changing section 201. This flush lower surface reduces water flow resistance, ensures smooth water flow, and prevents splashing. Furthermore, a stepped surface 5 is provided at the connection point between the secondary diameter-changing section 202 and the primary diameter-changing section 201. This stepped surface 5 increases the flow area at the connection point. Both the upper surfaces of the primary diameter-changing section 201 and the secondary diameter-changing section 202 are downward-sloping surfaces with lengths of 10mm-500mm and 20mm-386.16mm respectively. Within these ranges, the water discharge effect is maintained. The inclined surface gradually reduces the flow area of the secondary diameter-changing section 202, achieving the effect of water collection and pressurization, as well as the effect of water collection and flow. After being flushed into the pot 1, the water output is uniform and stable, preventing water swirl and splashing. At the same time, the primary diameter-changing section 201 and the secondary diameter-changing section 202 can also adopt an inclined surface method in which their upper and lower surfaces are tilted together to achieve the effect of shrinking the flow area. Furthermore, there will be two stepped surfaces 5 at the junction of the primary diameter-changing section 201 and the secondary diameter-changing section 202, which can achieve the effect of water collection and pressurization. The appropriate water pressure section structure can be selected according to the actual situation.
[0035] The working principle of this vortex flush toilet's pressurized water structure is as follows: During flushing, water in the toilet tank flows into the water channel 2 surrounding the toilet bowl 1 through the inlet 3. When the water flows within the primary diameter-changing section 201, the pressurization section on the primary diameter-changing section 201 pressurizes the water flow, increasing the initial velocity of the water flowing into the secondary diameter-changing section 202. Because the flow area at the beginning of the secondary diameter-changing section 202 is larger than that at the end of the primary diameter-changing section 201, the water flow velocity is reduced, weakening the impact force of the water flow on the inner wall of the water channel 2, thereby reducing noise generation. The water flow along the secondary diameter-changing section 202... As the flow area gradually decreases, the water velocity within the secondary diameter-changing section 202 increases again. After being ejected from the main flush hole 4, the flushing force of the water on the toilet bowl 1 increases, providing a thorough flush. Furthermore, as the water flows within the contracting secondary diameter-changing section 202, the flow becomes more concentrated. After being sprayed into the toilet bowl from the main flush hole 4, the water output becomes more even and stable, resulting in a better vortex formation effect. This ensures a thorough flush of the toilet bowl 1, guaranteeing a clean flushing effect, preventing water splashing, and preventing water from overflowing from the toilet bowl 1, thus improving flushing efficiency. The increased flushing force also reduces the amount of water used, achieving water conservation.
