Description

Technical Field

[0001] The invention belongs to the technical field of bathrooms, and in particular relates to a toilet flushing device. Background Art

[0002] In order to reduce the space occupied by the toilet, existing toilets place a water tank with an upward opening inside the ceramic base of the toilet. The sewage pipe in the ceramic base divides the internal space of the ceramic base into two parts, so the water tank is divided into two parts and located on both sides of the sewage pipe. At the same time, in order to enhance the impact of the water, two water pumps are set in the ceramic base and connected to the outer bottom surfaces of the two water tanks respectively. The two water tanks can be used for the wash ring and the main flush respectively. However, the two water pumps occupy the space inside the ceramic base, resulting in a reduction in the water storage capacity of the water tank, which affects the flushing effect. At the same time, the provision of two water pumps also leads to an increase in the production cost of the toilet. Summary of the Invention

[0023] To make the objectives, technical solutions, and effects of the present invention more clear, the following will provide a clear and complete description of the technical solutions of the present invention in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] Combine Figures 1 to 5 As shown, this embodiment provides a toilet flushing device, including a first water tank 11, a second water tank 12, a water pump 2 and a pipe 3. The first water hole 31 of the pipe is connected to the first water tank 11, the second water hole 32 of the pipe is connected to the second water tank 12, and the third water hole 33 is connected to the water inlet of the water pump 2. The water pump 2 is located in the first water tank 11, and the water outlet of the water pump 2 can be selectively connected to the toilet ring washing hole and the main flushing hole. Then, when the toilet is in the ring washing state and the main flushing state, the water in the first water tank 11 and the water in the second water tank 12 can be simultaneously transferred to the water pump 2, avoiding the water in the first water tank alone or the water in the second water tank alone being insufficient to flush the toilet, thereby ensuring the flushing effect of the ring washing function and the main flushing function.

[0026] In this embodiment, by providing a pipeline and a water pump, and utilizing the pipeline's two water inlet holes, water from the first water tank and the second water tank can be simultaneously integrated into the water pump. The water pump is placed within the first water tank, and the space between the water pump and the inner wall of the first water tank can be utilized to store water, thereby achieving the technical effect of increasing the water storage volume of the first water tank. The water pump is connected to the ring-washing hole and the main flushing hole, respectively, to achieve the ring-washing and main flushing operations of the toilet. Simultaneously, through the coordination between the single water pump and the pipeline, water from the first and second water tanks can be simultaneously utilized to achieve the ring-washing and main flushing functions, thereby ensuring sufficient water consumption for the ring-washing and main flushing functions and reducing the number of water pumps used. This not only reduces the space occupied by the water pump on the ceramic seat, thereby further increasing the water storage volume and enhancing the flushing effect of the toilet, but also achieves the technical effect of reducing the production cost of the toilet.

[0027] Combine Figure 2 and Figure 3 As shown, in this embodiment, the toilet flushing device also includes a third branch pipe 4. The ends of the third branch pipe 4 are connected to the third water hole 33 and the water inlet of the water pump 2, respectively, enabling communication between the pipeline and the water pump. In this case, when the toilet is flushing, water from the first and second water tanks enters the third water hole through the first and second water holes, respectively, and is then transported to the water pump through the third branch pipe.

[0028] In other embodiments, depending on the different communication methods between the water pump and the pipeline, only the first water hole and the second water hole can be set in the pipeline. The water inlet hole of the water pump is connected with the first water hole through the water in the first water tank. When the toilet is in the flushing state, the water in the first water tank gradually decreases and the water in the second water tank enters the first water tank through the second water hole and the first water hole in turn, which can also ensure that the water consumption in the wash state and the main flushing state is always sufficient.

[0029] Preferably, the connecting end of the pipe is located between the first water tank 11 and the second water tank 12, and the first water hole 31 and the second water hole 32 of the pipe are respectively located at both ends of the connecting end. The first water hole 31 of the pipe extends downward into the first water tank 11, and the second water hole 32 of the pipe extends downward into the second water tank 12. By using the upward openings of the first and second water tanks to achieve communication between the pipe and the first water tank and between the pipe and the second water tank, there is no need to consider the sealing of the connection points between the first and second water tanks and the pipe, thereby achieving the effect of improving the connection simplicity.

[0030] Combine Figure 5As shown, preferably, the first water hole 31 of the pipeline and the inner bottom surface of the first water tank 11, as well as the second water hole 32 of the pipeline and the inner bottom surface of the second water tank 12, are spaced apart, for example, at a spacing of 10 mm. Utilizing the spacing between the first water hole and the inner bottom surface of the first water tank, as well as the spacing between the second water hole and the inner bottom surface of the second water tank, the toilet can prevent sediment remaining on the inner bottom surfaces of the first and second water tanks from being drawn into the pipeline during flushing, thereby affecting the pumping effect and easily causing pipeline blockage. At the same time, the water stored on the inner bottom surfaces of the first and second water tanks can form a water seal on the pipeline, ensuring that there is always water in the pipeline, thus preventing all the water in the first and second water tanks and the pipeline from being drawn out, resulting in air remaining in the pipeline and affecting the next flushing effect, thereby ensuring the flushing effect of the toilet.

[0031] Combine Figure 2 、 Figure 3 and Figure 5 As shown, in this embodiment, the toilet flushing device also includes a first branch pipe 5 and a second branch pipe 6. The pipe 3 is a pipe of equal diameter. The first branch pipe 5 is connected to the first water hole 31 of the pipe, and the second branch pipe 6 is connected to the second water hole 32 of the pipe. The ratio of the cross-sectional area of ​​the water hole of the first branch pipe 5 to the cross-sectional area of ​​the water hole of the second branch pipe 6 is equal to the ratio of the water storage volume of the first water tank 11 to the water storage volume of the second water tank 12. In this way, the time required to completely pump out the water in the first water tank is the same as the time required to completely pump out the water in the second water tank, preventing the water in the first water tank or the second water tank from being prematurely pumped out, resulting in air in the pipe, causing the flushing water flow to be discontinuous and affecting the flushing effect. At the same time, using the first branch pipe and the second branch pipe to adjust the diameter of the first water hole and the second water hole respectively can improve the simplicity of pipe processing.

[0032] It should be noted that, since the water in the distance between the first water hole and the inner bottom surface of the first water tank and the water in the distance between the second water hole and the inner bottom surface of the second water tank cannot be extracted, the water storage volume of the first water tank is the actual water storage volume of the first water tank minus the water storage volume due to the distance. Similarly, the water storage volume of the second water tank is the actual water storage volume of the second water tank minus the water storage volume due to the distance.

[0033] Preferably, the first branch pipe 5 and the second branch pipe 6 are detachably fixedly connected to the pipeline 3 via threads, respectively, which can improve the convenience of repairing and replacing the first branch pipe and the second branch pipe.

[0034] Specifically, the experimental data are given in the table below, where the water consumption of the first water tank, the second water tank, and the total water consumption of 6S in water distribution scheme 1 are rounded to three decimal places, and the remaining data are rounded to two decimal places), that is, the cross-sectional areas of the three different first water holes and the second water holes, and the ratio of the cross-sectional area of ​​the first water hole to the cross-sectional area of ​​the second water hole is equal to the ratio of the water storage volume of the first water tank to the water storage volume of the second water tank; and each group has three first water tanks and second water tanks of different capacities. Taking water distribution scheme 1 as an example, the cross-sectional area of ​​the first water hole in the pipeline is 143.06mm 2 , the cross-sectional area of ​​the second water hole of the pipe is 44.16mm 2 , then it takes 6S for 1.30L of water in the first water tank and 0.4L of water in the second water tank to be discharged through the third water hole of the pipeline at the same time.

[0035]

[0036]

[0037] Of course, in other embodiments, depending on the different processing methods of the pipeline, the pipeline can also be made into a variable diameter, that is, the aperture of the pipeline itself remains unchanged, and the first water hole of the pipeline and the second water hole of the pipeline are set so that the ratio of the cross-sectional area of ​​the first water hole to the cross-sectional area of ​​the second water hole is equal to the ratio of the water storage volume of the first water tank to the water storage volume of the second water tank.

[0038] In addition, in this embodiment, when the toilet and the pipes are installed, it is necessary to leave more than 10 mm of water in the water tank and fill the pipes with water. Then, during the first and subsequent uses of the toilet, the water entering the water pump will never be mixed with air, thereby achieving the effect of improving the flushing effect of the toilet.

[0039] Of course, in other embodiments, the pipe can be directly installed in the water tank. In this case, there is air in the pipe, and there is no water in the first and second water tanks to seal the pipe. In this case, the toilet needs to be flushed before use to expel the air in the pipe. In this way, no air will enter the water pump during subsequent use, and the flushing effect of the toilet can also be ensured.

[0040] Combine Figure 1 and Figure 5 As shown, preferably, the water pump 2 is located on the inner bottom surface of the first water tank 11 and is connected to the inner bottom surface of the first water tank 11. The inner bottom surface of the first water tank can support the water pump and shorten the distance between the water pump and the main flushing hole and between the water pump and the wash ring hole, thereby improving the response speed of the flushing state and shortening the flushing time.

[0041] Further, combined Figures 1 to 3 As shown, in this embodiment, the water pump 2 is further provided with a base 21. The water pump 2 is mounted in the base 21. The horizontality of the bottom surface of the base can be used to increase the contact area between the water pump and the water tank, thereby improving the stability of the connection between the base and the water tank.

[0042] Preferably, the base 21 and the first water tank 11 are detachably connected by bolts, thereby improving the convenience of disassembly and maintenance of the base and the water tank.

[0043] In other embodiments, the water pump may be directly fixed to the inner bottom surface of the first water tank by glue to achieve a fixed connection between the water pump and the water tank.

[0044] In addition, in the present embodiment, the water pump is a submersible pump. In this way, the water pump can be immersed in water while avoiding damage to the water pump, thereby improving the safety of the water pump during use.

[0045] In other embodiments, depending on the type of water pump, an ordinary water pump can also be provided, and a waterproof shell can be provided along the outer contour of the water pump, which can also achieve the technical effect of the water pump working normally in water.

[0046] In addition, combined Figure 5 As shown, preferably, the toilet flushing device further includes a third water tank 13. The third water tank 13 is located above the first water tank 11 and the second water tank 12 and is connected to each other. The first water tank 11, the second water tank 12 and the third water tank 13 form an "n" shape. The third water tank can connect the upper parts of the first water tank and the second water tank, thereby increasing the water storage capacity of the water tank and further improving the flushing effect of the toilet.

[0047] Combine Figure 5 As shown, preferably, the pipe 3 is arranged and connected along the "N"-shaped profile formed by the right side wall of the first water tank 11, the bottom surface of the third water tank 13, and the left side wall of the second water tank 12. In this way, the bottom surface of the third water tank can be used to support the connecting end of the pipe, which can improve the stability of the pipe positioning.

[0048] Furthermore, the pipe 3 is detachably fixedly connected to the third water tank 13. For example, a clamping plate 131 is provided in the third water tank 13. The distance between the clamping plate 131 and the bottom surface 132 of the third water tank can be used to clamp and position the pipe, which not only improves the stability of the pipe positioning, but also improves the convenience of pipe maintenance and disassembly.

[0049] Combine Figure 1 and Figure 5As shown, in this embodiment, the toilet flushing device also includes a water inlet valve 7. The water inlet valve 7 is located within the second water tank 12, but can also be located within the first water tank 11. By locating the water pump and the water inlet valve in separate water tanks, the gravitational balance between the first and second water tanks can be improved, preventing positional displacement caused by the gravity difference between the first and second water tanks, thereby improving the stability of the connections between the first and second water tanks and the toilet. Furthermore, the connection between the water inlet valve and the water source can automatically control the opening and closing of the toilet water supply, thereby simplifying water supply.

[0050] Among them, the working water level of the toilet (that is, the water level after the toilet is in a stationary state and the first water tank, the second water tank and the third water tank are filled with water) is higher than the bottom surface of the third water tank. Therefore, when water is added, the water in the second water tank is first filled to be flush with the bottom surface of the third water tank, and then begins to flow into the first water tank. Finally, the water level in the third water tank rises to the working water level, the water inlet valve stops working and no water is added.

[0051] Of course, in other embodiments, depending on the different water inlet methods of the toilet, a faucet can also be used to directly connect the first water tank and the second water tank to supply water to the toilet.

[0052] In this embodiment, the toilet flushing device further includes a diverter valve. The diverter valve's water inlet is connected to a water pump, while its two outlets are connected to the main flushing hole and the rim-washing hole, respectively. This allows the water pump to selectively connect to the main flushing hole and the rim-washing hole, respectively. This allows the toilet to automatically control the timing of the main flushing and rim-washing states, and automatically switch between the two states, thereby improving the convenience of toilet use.

[0053] The above description is only a specific embodiment of the present invention. Under the above teachings of the present invention, those skilled in the art may make other improvements or modifications based on the above embodiments. Those skilled in the art should understand that the above description is only to better explain the purpose of the present invention, and the scope of protection of the present invention shall be based on the scope of protection of the claims.
