However, smart flush toilets now have more features, such as heated seats, light sensors, and automatic lid light. Smart toilets can be operated by electricity, and their automatic sensing and flushing functions are more popular, providing a better experience for people's home life. With the continuous advancement of technology, flush toilets are also constantly being improved.

[0003] However, most flush toilets currently in use are single-channel flushing toilets, or they split the water flow into two channels to flush the toilet seat and bottom when flushing. The flushing force is not strong enough and the flushing efficiency is not high. Utility Model Content

[0033] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0034] Example: Figure 1-5As shown, this utility model provides a technical solution: a bidirectional piston for toilet flushing, including a toilet flushing pump 1, an inlet 2 installed at one end of the toilet flushing pump 1, a first outlet 3 installed at the top of the toilet flushing pump 1, a second outlet 4 installed at the top of the toilet flushing pump 1, the input end of the toilet flushing pump 1 being electrically connected to the output end of an external power supply, the first outlet 3 and the second outlet 4 being symmetrically arranged at the top of the toilet flushing pump 1, and a water outlet mechanism 5 installed at the top of the first outlet 3.

[0035] The water outlet mechanism 5 includes a first water outlet pipe 501, a second water outlet pipe 502, a connecting pipe 503, a piston hole 504, a limiting short pipe 505, a limiting ring 506, a connecting hole 507, and an outer sleeve 508.

[0036] A first water outlet pipe 501 is installed at the top of the first water outlet 3, and a second water outlet pipe 502 is installed at the top of the second water outlet 4. The top of the first water outlet pipe 501 is connected to the toilet brush ring water channel, and the top of the second water outlet pipe 502 is connected to the toilet flushing water channel, realizing dual-outlet, dual-water flushing to enhance the flushing effect of the toilet. Both ends of the first water outlet pipe 501 and the second water outlet pipe 502 are equipped with connecting pipes 503. The first water outlet pipe 501 is connected to the first water outlet 3 through the bottom connecting pipe 503, and the second water outlet pipe 502 is connected to the second water outlet 4 through the bottom connecting pipe 503. The first water outlet pipe 501 and the second water outlet pipe 502 are both provided with piston holes 504 at the bottom and the second water outlet pipe 502 at the top. A limiting short pipe 505 is installed on the outside of the piston hole 504. A limiting ring 506 is installed on the outside of the limiting short pipe 505. A connecting hole 507 is provided on the top of the first water outlet pipe 501 and the bottom of the second water outlet pipe 502. An outer sleeve 508 is installed on the outside of the connecting hole 507. The outer sleeve 508 is sleeved on the outside of the limiting short pipe 505 and slides in contact with the limiting ring 506, so that the first water outlet pipe 501 and the second water outlet pipe 502 are connected.

[0037] Piston assembly 6 is installed inside piston bore 504;

[0038] Piston assembly 6 includes a first piston 601, a second piston 602, a limiting outer ring 603, and an annular limiting piece 604;

[0039] A first piston 601 is slidably engaged inside the piston hole 504 at the bottom of the first water outlet pipe 501. The sealed end of the first piston 601 is placed inside the first water outlet pipe 501. The outer diameter of the first piston 601 is the same as the inner diameter of the first water outlet pipe 501, so that the first piston 601 blocks the inside of the first water outlet pipe 501 and prevents water from flowing back into the first water outlet pipe 501 after flushing. A second piston 602 is slidably engaged inside the piston hole 504 at the top of the second water outlet 4. The first piston 601 and the second piston 602 have the same structure. Both the first piston 601 and the second piston 602 are equipped with a return spring to facilitate reset.

[0040] Both the first piston 601 and the second piston 602 are cylindrical structures with one open end and the other sealed. The sealed end of the second piston 602 is placed inside the second water outlet pipe 502. The outer diameter of the second piston 602 is the same as the inner diameter of the second water outlet pipe 502, so that the second piston 602 blocks the inside of the second water outlet pipe 502 and prevents water from flowing back into the second water outlet pipe 502 after flushing. One end of the first piston 601 and the second piston 602 are connected to a limiting outer ring 603. An annular limiting piece 604 is installed on one side of the limiting outer ring 603. The limiting outer ring 603 contacts one end of the limiting short pipe 505, and the outer side of the annular limiting piece 604 contacts the inner side of the outer sleeve 508, thereby facilitating the restriction of the movement position of the first piston 601 and the second piston 602.

[0041] The working principle and usage process of this utility model: After the toilet is used, the toilet starts the flushing operation. The toilet flushing pump drives water to enter from the inlet 2 and discharge from the first outlet 3 and the second outlet 4 respectively. The water from the first outlet 3 rushes into the first outlet pipe 501 and impacts the first piston 601. The impacted first piston 601 moves along the limiting short pipe 505 towards the second outlet pipe 502. The movement of the first piston 601 opens the channel of the first outlet pipe 501, so that the water rushes through the first outlet pipe 501 to the brush ring water channel of the toilet and finally rushes out from the top ring of the toilet. From the top ring of the toilet, it flows around the inner wall of the toilet and cleans the inner wall of the toilet.

[0042] Water from the second outlet 4 flows into the second outlet pipe 502 and impacts the second piston 602. The impacted second piston 602 moves along the limiting short pipe 505 toward the first outlet pipe 501. The movement of the second piston 602 opens the channel of the second outlet pipe 502, allowing water to flow through the second outlet pipe 502 into the flushing water channel of the toilet, directly flushing the bottom of the toilet and improving the flushing efficiency of excrement at the bottom of the toilet, thereby quickly cleaning the toilet.

[0043] like Figure 6As shown, the first piston 601 and the second piston 602 are bidirectionally arranged, which can impact and open the channel together when flushing the toilet, making it easier to flush. Compared with a single-channel flushing toilet, it flushes more cleanly. Compared with a flushing toilet that splits into two channels after the water comes out, it has a faster flushing speed and greater flushing force, resulting in higher overall flushing efficiency.

[0044] After flushing, the toilet flushing pump 1 stops working, the first water outlet 3 and the second water outlet 4 stop flowing water, and the water level inside the first water outlet pipe 501 and the second water outlet pipe 502 drops. At this time, the first piston 601 and the second piston 602 reset. The first piston 601 blocks the first water outlet pipe 501, and the second piston 602 blocks the second water outlet pipe 502 to prevent water backflow.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
