Description

Technical Field

[0001] The utility model relates to the technical field of bathrooms, in particular to a booster and a flushing mechanism with the same. Background Art

[0002] Currently, toilets are usually equipped with many flushing mechanisms. The water flow ejected by the flushing mechanism needs to have a certain intensity, which is a key factor in ensuring effective cleaning inside the toilet. A water flow with moderate intensity can not only quickly flush away dirt and residue, but also penetrate deep into the sewage outlet and corners to prevent dirt accumulation. However, the water pressure in the tap water pipe is constant. If you want to increase the flow rate of the water flow of the flushing mechanism, you usually use the method of reducing the water outlet. However, there is a limit to how much it can be reduced. If it is reduced too much, the water column will become thinner, reducing the cleaning surface and failing to cover the entire cleaning area. Another way to solve this problem is to add a booster device. This type of booster device is often equipped with a booster pump to control the flow rate of the water flow at the front end, resulting in increased production costs and is not suitable for low-end toilets. Summary of the Invention

[0003] The problem to be solved by the utility model is to provide a booster and a flushing mechanism with the same, which solves the problem of insufficient water flow speed in the current flushing mechanism, and has a simple and stable structure and low production cost.

[0004] The technical solution adopted by the present invention to solve the above-mentioned problem is: a supercharger, including a supercharger body, the interior of the supercharger body is hollow to form a cavity, the supercharger body is provided with a first joint and a second joint, the first joint is provided with an inlet channel, the second joint is provided with an outlet channel, wherein the diameter of the inlet channel is larger than the diameter of the outlet channel.

[0005] Compared with the existing technology, this booster effectively solves the problem of insufficient water flow rate in the current flushing mechanism. Under the condition of constant water supply flow, a cavity, an inlet channel and an outlet channel are set on the booster, and the diameter of the inlet channel is larger than the diameter of the outlet channel, so as to achieve the effect of a large cross-section at the water inlet end and a small cross-section at the water outlet end, thereby increasing the flow rate and further improving the flow efficiency of the fluid. The setting of the cavity allows the fluid to be retained in the cavity when it is input from the inlet channel, first filling the cavity and discharging the gas carried in the water flow to make the fluid in a relatively stable state, avoiding the fluid being directly output from the outlet channel, which causes internal gas to remain and makes the fluid output in the initial stage unstable. The structural design of the booster is simple and stable, avoiding complex components and assembly processes, thereby reducing costs during the production process. Compared with the existing technology, which often has problems of complex structure and high cost, the design of this booster fully considers the feasibility of production and adopts a simple structure, which significantly reduces the production cost.

[0006] Furthermore, the inlet channel and the outlet channel are relatively arranged at the two ends of the axis of the cavity. When the fluid flows along the axis of the cavity, the sudden change of flow direction can be reduced, thereby reducing the generation of turbulence. The axial flow also helps to evenly distribute the fluid, avoid the occurrence of dead zones inside the cavity, and improve the stability of the flow. Smooth flow can reduce pressure loss and improve flow efficiency.

[0007] Furthermore, the cavity includes a cylindrical cavity and a first tapered cavity and a second tapered cavity, respectively, disposed at either end of the cylindrical cavity axis. The first tapered cavity is used to form a tapered transition from the cylindrical cavity to the inlet channel, and the second tapered cavity is used to form a tapered transition from the cylindrical cavity to the outlet channel. The first and second tapered cavities, disposed at either end of the cylindrical cavity axis, increase flow velocity through their tapered narrowing shapes, thereby helping to reduce the residence time of the fluid within the cavity.

[0008] Furthermore, the diameter of the outlet channel is 40% to 80% of the diameter of the inlet channel.

[0009] To address the above-mentioned technical problems, the present application provides another technical solution: a flushing mechanism mounted on a toilet body, the toilet body comprising a pelvic cavity, an upper flushing port located above the pelvic cavity, and a lower flushing port located below the pelvic cavity. The toilet body is further provided with the aforementioned booster, pulse valve, upper flushing nozzle, and lower flushing nozzle. The booster is connected to the water inlet of the pulse valve via a connecting pipe, and the two water outlets of the pulse valve are connected to the upper flushing nozzle and the lower flushing nozzle, respectively, via connecting hoses. The water outlet of the upper flushing nozzle faces the upper flushing port, and the lower flushing nozzle faces the lower flushing port. This structure achieves significant economic benefits and improved structural stability by eliminating the electric boosting valve and adopting the physical boosting principle. Its advantages include: significantly reducing costs and avoiding the use and maintenance costs of complex electrical components; a simple and stable structure, reducing failure points, improving reliability and durability, and ensuring a more comprehensive and efficient flushing effect.

[0010] Furthermore, the outer walls of the first joint and the second joint are both provided with threads for connecting and fixing with the internal threads of the end of the connecting pipe. This structure improves the stability and sealing of the connection.

[0011] In order to solve the above technical problems, the present application provides another technical solution: a flushing mechanism installed on the back seat of the toilet, wherein the back seat is equipped with an inlet valve, the above-mentioned booster, a slide rail, a spray rod, and a fixed pipe. The water inlet end of the water inlet valve is connected to the tap water pipe, and the water outlet end is connected to the first connector of the booster through a connecting hose. The second connector of the booster is connected to the lower end of the fixed pipe through a connecting hose. The upper end of the fixed pipe is connected to the water inlet end of the spray rod through a connecting hose. The spray rod is slidably connected to the slide rail. By adopting physical boosting instead of an electric boosting valve, the cost is significantly reduced, the need for maintenance and replacement of electrical components is avoided, and thus the economy is improved. Secondly, the structure is simple and stable, which reduces the failure points, enhances the reliability of the system, and reduces potential problems during use.

[0012] Furthermore, the ends of the first connector and the second connector are both provided with connecting protrusions for plugging in the connecting hose, and the connecting protrusions include an inclined insertion surface and a vertically set limiting surface. The insertion surface is arranged on the outside of the first connector or the second connector and is used to radially expand the connecting hose when plugging in the connecting hose, while the limiting surface is arranged on the inside of the first connector or the second connector and is used to limit the plug-in hose from falling out toward the outside.
