Description

Technical Field

[0001] This utility model relates to the field of toilets, and in particular to a silent flushing system. Background Technology

[0002] Current toilets typically perform two flushes (usually achieved through a water path switching device). The first flush cleans the inner walls of the toilet bowl (a process known as rim flushing), while the second flush sprays water from the bottom of the bowl to create a siphon effect (a process known as jet flushing). However, the high velocity of the jet during the second flush results in a higher vibration frequency and amplitude, leading to more jarring noise. This is especially noticeable when the siphon pipe is completely emptied, creating a cavity inside the toilet bowl into which the high-speed fluid is directly injected, generating significant noise and negatively impacting the user experience.

[0003] In view of the above problems, it is necessary to study a silent flushing system that can reduce the flushing noise of the toilet. Utility Model Content

[0004] The purpose of this invention is to provide a silent flushing system that reduces the flushing noise of the toilet.

[0005] To achieve the above objectives, the solution of this utility model is: A silent flushing system includes a flushing pump, a main outlet pipe, a brush ring water outlet pipe, a jet water outlet pipe, and a one-way valve assembly. The outlet of the flushing pump is connected to the inlet of the main outlet pipe, and the power of the flushing pump can be switched. The main outlet pipe is connected to the inlet of the brush ring water outlet pipe and the inlet of the jet water outlet pipe. A valve chamber is formed inside the jet water outlet pipe, and the two ends of the valve chamber form an inlet communicating with the inlet of the jet water outlet pipe and an outlet communicating with the outlet of the jet water outlet pipe, respectively. The one-way valve assembly includes a valve core and a return spring. The valve core is movably housed in the valve chamber and movably blocks the inlet. The two ends of the return spring abut against the valve core and the inner wall of the valve chamber, respectively, and the return spring is used to drive the valve core to block the inlet.

[0006] The valve core has an annular groove for the insertion of a reset spring.

[0007] The valve cavity contains a sleeve for the reset spring to engage.

[0008] Multiple guide ribs are formed inside the valve cavity, abutting against the outer wall of the valve core, and water passages are formed between adjacent guide ribs.

[0009] The water jet outlet pipe includes two connected pipes, with the valve chamber formed between the two pipes.

[0010] After adopting the above solution, the working principle of the silent flushing system of this utility model is as follows: During the initial flushing phase (the first flush), the flush pump operates at low power, drawing water from the toilet tank into the main outlet pipe. At this time, some of the water flows into the brush seat outlet pipe, causing it to output brush seat water. The remaining water flows into the jet water outlet pipe. Due to the low power of the flush pump, the flushing force of the water entering the jet water outlet pipe is insufficient to open the one-way valve assembly. Thus, the water pumped by the pump only flows out through the brush seat outlet pipe, allowing the toilet to only output brush seat water to flush the inner wall of the toilet bowl. During the later stages of the toilet flush (i.e., the second flush), the flush pump operates at high power, drawing water from the toilet tank into the main outlet pipe. At this time, part of the water in the main outlet pipe flows into the brush seat outlet pipe, causing the brush seat outlet pipe to output brush seat water. The remaining water in the main outlet pipe flows into the jet water outlet pipe. Due to the high-power operation of the flush pump, the force of the water flow input into the jet water outlet pipe drives the one-way valve assembly to open the jet water outlet pipe, causing the jet water outlet pipe to output jet water. In this way, the water flow drawn by the pump is output through the brush seat outlet pipe and the jet water outlet pipe, thereby causing the toilet to output brush seat water to flush the inner wall of the toilet bowl, while the toilet outputs jet water to the jet nozzle to create a siphon effect.

[0011] As described above, this invention continuously outputs water through the flushing ring during the toilet's flushing process. This ensures that the water at the bottom of the toilet bowl is constantly replenished while being drained, maintaining a consistent water level in the bowl. This prevents the formation of cavities in the toilet's drainage system, thus reducing noise. Furthermore, the water from the flushing ring buffers the spray, preventing it from directly hitting the toilet bowl wall, further reducing noise. In summary, this invention's silent flushing system results in low flushing noise. In addition, this invention's silent flushing system has fewer components and a simpler structure.

Water outlet pipe for brush ring The jet water outlet pipe 4, pipe body 40, valve chamber 400, water inlet 401, water outlet 402, guide rib 403, sleeve 404, one-way valve assembly 5, valve core 51, annular groove 511, and return spring 52. Detailed Implementation

[0015] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0016] like Figure 1 and Figure 2 As shown, this utility model discloses a silent flushing system, which includes a flushing water pump 1, a main water outlet pipe 2, a brush ring water outlet pipe 3, a jet water outlet pipe 4, and a one-way valve assembly 5; wherein, the water outlet end of the flushing water pump 1 is connected to the water inlet end of the main water outlet pipe 2, and the power of the flushing water pump 1 can be switched; the main water outlet pipe is connected to the water inlet end of the brush ring water outlet pipe 3 and the water inlet end of the jet water outlet pipe 4, and the one-way valve assembly 5 is installed in the jet water outlet pipe 4, which enables the jet water outlet pipe 4 to discharge water in one direction.

[0017] The working principle of the silent flushing system of this utility model is as follows: During the initial flushing phase (the first flush), the flush pump 1 operates at low power, drawing water from the toilet tank into the main outlet pipe 2. At this time, part of the water in the main outlet pipe 2 flows into the brush ring water outlet pipe 3, causing the brush ring water outlet pipe 3 to output brush ring water. The remaining water in the main outlet pipe 2 flows into the jet water outlet pipe 4. However, due to the low power operation of the flush pump 1, the flushing force of the water flow into the jet water outlet pipe 4 is insufficient to drive the one-way valve assembly 5 to open the jet water outlet pipe 4. Thus, the water flow drawn by the pump is only output through the brush ring water outlet pipe 3, so that the toilet only outputs brush ring water to flush the inner wall of the toilet bowl. During the later stages of toilet flushing (i.e., the second flush), the flush pump 1 operates at high power, drawing water from the toilet tank into the main outlet pipe 2. At this time, part of the water in the main outlet pipe 2 flows into the brush ring water outlet pipe 3, causing the brush ring water outlet pipe 3 to output brush ring water. The remaining water in the main outlet pipe 2 flows into the jet water outlet pipe 4. Due to the high-power operation of the flush pump 1, the force of the water flow input into the jet water outlet pipe 4 drives the one-way valve assembly 5 to open the jet water outlet pipe 4, causing the jet water outlet pipe 4 to output jet water. Thus, the water flow drawn by the pump is output through the brush ring water outlet pipe 3 and the jet water outlet pipe 4, thereby causing the toilet to output brush ring water to flush the inner wall of the toilet bowl. At the same time, the toilet outputs jet water to the toilet's jet nozzle to create a siphon effect.

[0018] As described above, this invention continuously outputs water through the flushing ring during the toilet's flushing process. This ensures that the water at the bottom of the toilet bowl is constantly replenished while being drained, maintaining a consistent water level in the bowl. This prevents the formation of cavities in the toilet's drainage system, thus reducing noise. Furthermore, the water from the flushing ring buffers the spray, preventing it from directly hitting the toilet bowl wall, further reducing noise. In summary, this invention's silent flushing system results in low flushing noise. In addition, this invention's silent flushing system has fewer components and a simpler structure.

[0019] In an embodiment of this utility model, a valve cavity 400 is formed inside the jet water outlet pipe 4. The two ends of the valve cavity 400 are respectively formed with an inlet 401 communicating with the inlet end of the jet water outlet pipe 4 and an outlet 402 communicating with the outlet end of the jet water outlet pipe 4. The one-way valve assembly 5 includes a valve core 51 and a return spring 52. The valve core 51 is movably housed in the valve cavity 400 and the valve core 51 movably blocks the inlet 401. The two ends of the return spring 52 abut against the valve core 51 and the inner wall of the valve cavity 400 respectively, and the return spring 52 is used to drive the valve core 51 to block the inlet 401. The jet water outlet pipe 4 includes two connected pipe bodies 40, with a valve cavity 400 formed between the two pipe bodies 40 for installing a one-way valve assembly 5. Multiple guide ribs 403 abutting against the outer wall of the valve core 51 are formed inside the valve cavity 400 to ensure smooth movement of the valve core 51. A water passage is formed between adjacent guide ribs 403 for water passage. A sleeve 404 for the reset spring 52 to engage may be formed inside the valve cavity 400 to prevent displacement of the reset spring 52. The valve core 51 may have an annular groove 511 for the reset spring 52 to engage to prevent displacement of the reset spring 52.

[0020] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
