Description

Technical Field

[0001] This utility model relates to the field of toilet technology, and more specifically to a vortex flush toilet. Background Technology

[0002] In the development of toilet technology, most toilets currently consist primarily of a toilet bowl and a water tank. The upper part of the toilet bowl has a flushing channel connected to the bowl via several flush nozzles, while the lower part also has a flushing channel extending to the bottom of the bowl. The flushing function is achieved by controlling the flush nozzles on the bowl via the water tank. However, because the flush nozzles are located at the top of the bowl, the water flow is significantly reduced in speed as it reaches the bottom due to air resistance, friction between the water and the bowl wall, and other factors. This not only makes it difficult to clean the toilet bowl thoroughly but also results in a substantial waste of water.

[0003] To address the aforementioned issues, vortex-flush toilets have emerged on the market, such as the vortex-flush siphon toilet disclosed in Chinese Patent Publication No. CN219825495U. This toilet, by incorporating a vortex-flush and siphon structure, enhances the flushing force and cleaning effect to some extent. However, this solution still has significant drawbacks: firstly, its flushing relies primarily on gravity, limiting the flushing pressure, which remains insufficient to effectively clean stubborn stains or larger waste; secondly, relying solely on the siphon structure for waste removal limits the flushing power, leading to insufficient pressure when encountering large or sticky excrement, easily causing toilet blockages and severely impacting user experience and normal toilet use. Therefore, further innovation and improvement of the existing vortex-flush toilet structure are urgently needed to overcome these technical challenges. Summary of the Invention

[0004] The purpose of this invention is to provide a stable, reliable, powerful, and efficient vortex flush toilet that addresses the shortcomings of existing technologies.

[0005] This utility model achieves the above-mentioned objectives using the following technical solution: A vortex flush toilet, characterized in that it includes a toilet body, a water tank, an inlet valve, an inlet pipe, a water pump, a water distributor, a cleaning nozzle, and an auxiliary flush nozzle. A vortex flushing channel is provided on the upper part of the toilet bowl of the toilet body, and a corresponding clearance hole is provided on the rear side of the toilet bowl. The cleaning nozzle is located on the clearance hole to achieve efficient flushing of the upper part and inner wall of the toilet bowl. A drain outlet and a siphon pipe connecting to the drain outlet are provided at the lower part of the toilet bowl. The auxiliary flush nozzle is located inside the drain outlet to provide additional power for the flushing process. The inlet valve is located inside the water tank, and the inlet pipe is connected to the inlet valve. The water tank is connected to a flushing pipe, which is connected to the water pump and the water distributor. The water distributor is connected to a first flushing branch and a second flushing branch. The first flushing branch is connected to the cleaning nozzle to deliver water to the cleaning nozzle, and the second flushing branch is connected to the auxiliary flush nozzle to supply water to the auxiliary flush nozzle.

[0006] As a further explanation of the above scheme, the auxiliary flushing nozzle is set at an upward angle, and the nozzle adopts a structure with a large inlet and a small outlet. Utilizing the principles of fluid mechanics, the speed of the flushing water flow can be significantly increased.

[0007] Furthermore, the auxiliary flush nozzle is directed towards the inlet of the siphon pipe, forming an angle of 20-60 degrees with the ground. This angle setting has been verified through numerous experiments to ensure that the water flow acts on the drain outlet and the siphon pipe inlet at the optimal angle and force, effectively improving the sewage discharge effect and reducing the probability of blockage.

[0008] Furthermore, the water tank is equipped with a toilet cleaning liquid container, the cleaning nozzle is connected to a cleaning liquid pipe, the toilet cleaning liquid container is connected to the cleaning liquid pipe, and the toilet cleaning liquid container has a pipe connecting to the water tank.

[0009] Furthermore, an overflow port is provided on the upper side of the water tank, which is connected to the clearance hole to form an overflow channel, effectively preventing the water tank from overflowing.

[0010] Furthermore, the water inlet pipe is connected to a T-joint, with branch one of the T-joint connecting to the water tank, and branch two of the T-joint connecting to a feminine wash water pipe.

[0011] Furthermore, the toilet bowl has an odor extraction vent at the rear to remove odors and keep the bathroom air fresh.

[0012] The beneficial effects that this utility model can achieve by adopting the above-mentioned technical solution are:

[0013] 1. This utility model adopts a decoupled vortex flush toilet mainly composed of a toilet body, water tank, inlet valve, inlet pipe, water pump, water distributor, cleaning nozzle, and auxiliary flush nozzle. By setting up the water pump, the flushing pressure is significantly improved. In conjunction with the cleaning nozzle and vortex flushing channel, a powerful vortex flushing water flow can be generated to perform all-round, high-intensity flushing of the toilet bowl, effectively removing stubborn stains and ensuring that the toilet is clean without dead corners. The auxiliary flush nozzle provides additional strong water flow power during sewage discharge. Working in synergy with the siphon structure, it greatly enhances the sewage discharge capacity, effectively solving the clogging problem caused by insufficient sewage discharge pressure in traditional toilets, and improving the sewage discharge efficiency and reliability of the toilet.

[0014] 2. This utility model adopts an overflow channel between the water tank and the toilet bowl, which effectively avoids the potential hazards caused by water overflow from the water tank, ensures the safety of the bathroom environment and facilities, and makes the toilet more stable and reliable in use.

[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings, making the technical solution and beneficial effects of this utility model clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0026] like Figures 1-5As shown, this utility model is a vortex flush toilet, including a toilet body 1, a water tank 2, a water inlet valve 3, a water inlet pipe 4, a water pump 5, a water distributor 6, a cleaning nozzle 7, and an auxiliary flush nozzle 8. A vortex flushing channel 1-2 is provided on the upper part of the toilet bowl 1-1 of the toilet body 1. The vortex flushing channel 1-2 is arranged circumferentially along the upper edge of the toilet bowl 1-1. The toilet bowl of the toilet body is manufactured using a one-piece molding process. A clearance hole 1-3 corresponding to the vortex flushing channel is provided on the rear side of the toilet bowl 1-1. The cleaning nozzle 7 is disposed on the clearance hole 1-3 to achieve efficient flushing of the upper part and inner wall of the toilet bowl. The lower part of the toilet bowl 1-1 is equipped with a drain outlet 1-4 and a siphon pipe 1-5 connecting to the drain outlet. An auxiliary flushing nozzle 7 is located inside the drain outlet 1-4 to provide additional power for the flushing process. The drain outlet at the bottom of the toilet bowl is funnel-shaped, with a large diameter end of 80-100mm and a small diameter end connected to the siphon pipe. The siphon pipe adopts an S-shaped structure design, with a smooth interior and an inner diameter of 50-60mm, effectively creating a siphon effect. The water inlet valve 3 is located inside the water tank 2, and the water inlet pipe 4 connects to the water inlet valve 3. The water inlet pipe uses a 20mm inner diameter PPR pipe, capable of withstanding water pressure of 0.1-0.6MPa. The water tank 2 is connected to a flushing pipe 9, which is sequentially connected to the water pump and water distributor via the flushing pipe. The flushing pipe also uses a 25mm diameter PPR pipe. The flushing pipe 9 is connected in sequence to the water pump 5 and the water distributor 6. The water distributor 6 is connected to the first flushing branch 10 and the second flushing branch 11. The first flushing branch 10 is connected to the cleaning nozzle 7 and is used to deliver water to the cleaning nozzle. The second flushing branch 11 is connected to the auxiliary flushing nozzle 8 and is used to supply water to the auxiliary flushing nozzle.

[0027] The auxiliary flush nozzle 8 is angled upwards and features a unique large-hole inlet and small-hole outlet structure. The large hole has a diameter of 10mm, and the small hole has a diameter of 5mm. According to Bernoulli's principle, this structure significantly increases the velocity of the water flow as it passes through the nozzle. The main body of the auxiliary flush nozzle is made of stainless steel. Simultaneously, the auxiliary flush nozzle faces the inlet of the siphon pipe, forming a 22-degree angle with the ground. This angle has been verified through extensive experimentation to ensure that the water flow acts on the drain outlet and siphon pipe inlet at the optimal angle and force, effectively improving the sewage discharge effect and reducing the probability of blockage.

[0028] The water tank 2 contains a dedicated toilet cleaning solution container 12. The cleaning nozzle 7 is connected to a cleaning solution pipe. The toilet cleaning solution container 12 is connected to the cleaning solution pipe via a pipe, and the toilet cleaning solution container also has a pipe connecting to the water tank 2. During flushing, the water flow in the tank carries the cleaning solution in the container, which mixes with the water flow through the cleaning solution pipe and is then sprayed out through the cleaning nozzle, achieving deep cleaning and disinfection of the toilet and further improving the cleanliness and hygiene of the toilet.

[0029] The water tank 2 is equipped with an overflow port 2-1 on the upper side, which is connected to the clearance hole to form a complete overflow channel. When the water level in the water tank exceeds the set maximum water level, the excess water will flow into the overflow channel through the overflow port and finally be discharged from the clearance hole, preventing the water tank from overflowing and protecting the bathroom environment and the surrounding facilities of the toilet.

[0030] The water inlet pipe 4 is connected to a T-joint 13. Branch 13-1 of the T-joint 13 connects to the water tank 2, providing water for toilet flushing. Branch 2 13-2 of the T-joint 13 connects to a feminine wash water pipe and a corresponding bidet nozzle, expanding the toilet's functionality and meeting diverse user needs. However, since bidet nozzles are quite common, their specific structure will not be described in detail here. The toilet bowl has an odor extraction port 1-6 at the rear, which can be connected to an external deodorizing device to promptly remove odors from the bowl and maintain fresh air in the bathroom. The deodorizing device uses physical deodorization; chemical decomposition deodorization can also be used. In this embodiment, the deodorizing device is a small box that can be installed externally at the odor extraction port at the rear of the toilet bowl using a snap-fit ​​or magnetic method. The box contains a multi-layered filter structure. The outermost layer is a coarse filter to intercept large particles; the middle layer is filled with activated carbon particles, which have a rich porous structure and a large specific surface area to effectively adsorb odor molecules; the innermost layer is a fine filter to prevent activated carbon particles from falling off. An air inlet is located on one side of the box, connected to the toilet odor extraction port, and an air outlet is located on the other side. Air passes through the filter to absorb odors and is then discharged from the outlet, achieving an air purification effect.

[0031] Compared with existing technologies, this invention significantly increases flushing pressure through the addition of a water pump. Combined with the cleaning nozzles and swirling flushing channels, it generates a powerful swirling water flow, providing a comprehensive and high-intensity flush of the toilet bowl, effectively removing stubborn stains and ensuring thorough cleaning. Furthermore, the unique structure and angle of the auxiliary flushing nozzles provide additional powerful water flow during flushing, working in conjunction with the siphon structure to greatly enhance flushing capacity. This effectively solves the clogging problem caused by insufficient flushing pressure in traditional toilets, improving flushing efficiency and reliability. It integrates multiple functions such as cleaning solution addition, feminine wash supply, and deodorization. The cleaning solution addition function enables automatic cleaning and disinfection of the toilet. The feminine wash pipe meets the special cleaning needs of female users. The odor extraction vent keeps the bathroom air fresh, enhancing the user experience and quality of life. The overflow channel effectively avoids the potential hazards of water tank overflow, ensuring the safety of the bathroom environment and facilities, making the toilet more stable and reliable.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
