Description

Technical Field

[0001] The utility model relates to the technical field of toilet pipelines, in particular to a split flushing pipeline for a toilet. Background Art

[0002] The main drawback of a toilet is that flushing depends on the ceramic flushing pipeline of the toilet itself. The smoothness of the flushing pipeline directly affects the flushing effect. If the flushing pipeline of the toilet has poor smoothness, the water flow energy loss is large, and it is difficult to achieve the optimal flushing effect, especially for a sunken intelligent toilet with high requirements for the potential energy conversion rate of the water tank. Sunken toilets are becoming more and more popular. Due to the poor smoothness of the flushing pipeline not meeting the characteristics of fluid mechanics, the flushing ability is generally weak. To achieve a certain ability to carry away dirt, the method of increasing the water consumption is often used to solve the problem, resulting in a certain degree of water waste.

[0006] To achieve this purpose, the present utility model adopts the following technical solutions:

[0030] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0031] Example 1

[0032] like Figure 1-6 As shown, the utility model provides a split flushing pipe for a toilet, comprising a connecting pipe 1, wherein a first connecting portion 2 and a second connecting portion 3 are provided at both ends of the connecting pipe 1, which are respectively used to connect with the flushing end of the toilet and the water inlet end of the toilet tank, and at the same time, when the flushing pipe is installed, the height of the second connecting portion 3 is higher than the height of the first connecting portion 2, so that the connecting pipe 1 is tilted between the first connecting portion 2 and the second connecting portion 3.

[0033] The first connection part 2 and the second connection part 3 are set to soft materials, such as rubber; the soft first connection part 2 and the second connection part 3 make installation convenient. Soft materials usually have good softness and bendability, which makes installation and connection more flexible and convenient. Especially when connecting the toilet and the water source pipeline, the hose can more easily adapt to different installation environments and angles, reducing the difficulty of installation. And the hose has a certain elasticity, which can absorb and alleviate the vibration and noise generated when the water flow hits the pipeline to a certain extent, thereby providing a quieter and more comfortable use experience. The connecting pipe 1 is set to a hard material, such as ceramic or plastic, such as PVC, so that the connecting pipe 1 has higher strength and durability. In the toilet flushing pipeline, the middle section uses a hard pipe to ensure that the pipeline can withstand higher water pressure and impact force, reduce the risk of rupture or leakage, and at the same time, it has good self-supporting performance, which can support the weight of the pipeline and the pressure generated by the internal water flow to a certain extent. Especially when the pipeline is long or needs to cross a certain distance, the hard pipe can provide a more stable support.

[0034] In order to maximize the efficiency of the flushing pipe, the inclination angle of the connecting pipe 1 is between 3°-10°, preferably 6°. By such an inclined setting, the downwardly inclined pipe design utilizes the natural effect of gravity, so that the wastewater can flow down the pipe more smoothly, improving the drainage efficiency. This design helps the wastewater to be discharged quickly, avoids accumulation in the pipe, reduces the risk of blockage, and can ensure that the wastewater can flow smoothly to the sewer pipe, avoiding stagnation or water accumulation in the pipe. And the downwardly inclined pipe design will form a certain water seal in the first connecting part 2, that is, a certain amount of water is always maintained in the first connecting part 2, which becomes a good barrier to seal the odor, preventing the odor in the sewer from flowing back to the bathroom and polluting the indoor air. It can not only prevent the odor from flowing back, but also open the inspection port at the elbow to remove the slag in the pipe, which is convenient for the maintenance and cleaning of the pipe. The downwardly inclined pipe may also be combined with the siphon principle.

[0035] Add a second connecting part 3, that is, increase the water flow impact between the connecting pipe 1 and the toilet water tank. The second connecting part 3 includes a top connecting section 301 and a bottom connecting section 302. The top connecting section 301 and the bottom connecting section 302 are respectively communicated with the top wall and the bottom wall of the connecting pipe 1. The distance from the top connecting section 301 to the connecting pipe 1 is less than the distance from the bottom connecting section 302 to the connecting pipe 1. That is, the width of the top connecting section 301 is less than the width of the bottom connecting section 302. According to the principle of fluid mechanics, when water flows in the pipe, this structure will have a certain restrictive effect on the upper water flow, thereby increasing the water flow speed in the lower part. The increase in flow rate means that the amount of water passing through the pipe per unit time increases, which helps to improve the water supply efficiency.

[0036] In order to make the flow increasing effect of the bottom connecting section 302 better, the bottom connecting section 302 further includes a slope 3021 and an arc slope 3022. The arc slope 3022 is connected from the water outlet of the toilet water tank and then communicated with the slope 3021. The water flow potential energy is increased through the arc slope 3022 and then impacted through the slope 3021. The angle between the slope 3021 and the arc slope 3022 is between 130°-160°.

[0037] A flow increasing part 4 is arranged between the first connecting part 2 and the connecting pipe 1. The opening of the flow increasing part 4 gradually decreases towards the inside. With the total water flow remaining unchanged, the flow rate increases. Due to the increase in flow rate, the dynamic pressure of the fluid will also increase accordingly.

[0038] The first connecting part 2 is set as a semi-circular bend. Therefore, in order to adapt to the shape of the first connecting part 2, the slope on the side of the flow increasing part 4 away from the first connecting part 2 is less than the slope on the side of the flow increasing part 4 close to the first connecting part 2. When flushing, the water flow quickly surges into the pipe, and with the help of the bend design of the first connecting part 2, an instantaneous vacuum state is formed, thereby generating a strong suction force to take away the dirt together. This design helps to improve the flushing effect and reduce the possibility of blockage.

[0039] To increase the stability of the flushing pipe, a fixing component 5 is arranged at the connection. The fixing component includes a fixing buckle 501 and a fixing ring 502. The fixing ring 502 is arranged around the outside of the connection, and the fixing buckle 501 is used to fix the fixing ring 502.

[0040] Embodiment 2

[0041] As Figure 7 shown, the caliber of the connection between the first connecting part 2 and the toilet flushing water outlet is less than or equal to the caliber of the connection between the flow increasing part 4 and the first connecting part 2, so that the caliber size of the first connecting part 2 can be customized according to requirements.

[0042] The present utility model is described through preferred embodiments. Those skilled in the art will appreciate that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present utility model. The present utility model is not limited by the specific embodiments disclosed herein, and other embodiments falling within the scope of the claims of this application belong to the scope of protection of the present utility model.
