[0001] The present invention relates to the technical field of foaming process flow, and in particular to a foaming flushing method and system for a toilet, and the toilet. Background Art

[0002] Currently, all toilets are equipped with a water trap. Its purpose is to isolate the bathroom from the sewer, preventing odors from the sewer from flowing back into the room and affecting indoor air quality. However, if the toilet is not used for a long time and the water in the trap is not replaced, it can easily become smelly and breed bacteria, affecting human health and hygiene. Long-term immersion in water can also lead to scale deposits and adsorption on the toilet walls, causing them to turn yellow and become difficult to clean.

[0003] The current approach to solving this problem involves throwing a "Smurf" into the water tank. However, due to the differences in toilet types, such as tankless toilets, this "Smurf" solution is not applicable. This approach is difficult to implement in smart toilets. Summary of the Invention

[0011] Furthermore, the flow rate of water from the water inlet structure entering the final-stage dilution chamber is greater than the flow rate of water from the water inlet structure entering the first-stage dilution chamber.

DETAILED DESCRIPTION

[0033] The following combination Figure 1-7 The present invention will be described in detail.

[0034] A toilet foaming flushing method is performed before a user uses the toilet, after flushing is completed, or when the toilet has not been flushed for a long time. The method includes a first foaming stage, a second foaming stage, and a third foaming stage that are performed sequentially in one foaming cycle. Specifically:

[0035] In the first foaming stage, a first dose of foaming agent is added to the foaming module through the foaming agent inlet provided in the foaming module, and the foaming module performs a foaming operation. The foaming module is installed on the toilet body 80;

[0036] In the second foaming stage, no foaming agent is added to the foaming module, and the foaming module performs foaming two to four times based on the first dose of foaming agent, and during the foaming process of the second foaming stage, the foamed mixed liquid is discharged from the mixed liquid outlet provided in the foaming module;

[0037] In the third foaming stage, after the second dose of foaming agent is added to the foaming module, the foaming module performs foaming once. During the foaming process in the third foaming stage, the foaming mixed liquid is discharged from the mixed liquid outlet provided in the foaming module, and the foaming agent content in the foaming mixed liquid in the third foaming stage is higher than the total amount of the foaming agent content in the foaming mixed liquid in the first foaming stage and the second foaming stage.

[0038] Therefore, the foaming flushing method includes a maximum of five foaming processes in one foaming cycle. The foaming agent contains lubricating and bactericidal components. The first foaming stage and the second foaming stage are foamed multiple times with the same amount of foaming agent used. The lubricating and bactericidal components contained are low in content, and the generated substance is mainly foam. The foam covers the water surface, and its function is to isolate odor and prevent splashing, avoid waste of foaming agent, and ensure that the foaming agent and water are evenly mixed, thereby ensuring the foaming effect. In the third foaming stage, a foaming agent greater than the first dose is added, and the number of foaming times is once. The discharged substance is a foaming mixture. The generated foaming mixture contains a higher dose of foaming agent, so that the foaming mixture is integrated with the water stored in the trap to form a bactericide, thereby avoiding the water stored in the trap causing scale deposition and bacterial growth on the toilet surface during the immersion process due to long-term non-use of the toilet.

[0039] In this embodiment, the foaming module includes a water inlet structure, a mixed liquid outlet 403, a mixing chamber 504, a foaming agent storage chamber 505 and a liquid pump 60, and also includes a plurality of dilution chambers, each of which is connected one by one to form a multi-stage dilution structure; the water inlet structure is connected to the first-stage dilution chamber 502 and the last-stage dilution chamber 503 of the multi-stage dilution structure, the inlet of the liquid pump 60 is connected to the foaming agent outlet 506 of the foaming agent storage chamber 505, and the outlet of the liquid pump 60 is connected to the foaming agent inlet 404 of the first-stage dilution chamber 502; the last-stage dilution chamber 503 is connected to the mixing chamber 504, and the mixing chamber 504 is connected to the mixed liquid outlet 403.

[0040] In this embodiment, the first-stage dilution chamber 502 refers to the dilution chamber that performs the first-stage dilution in a multi-stage dilution structure, and the final-stage dilution chamber 503 refers to the dilution chamber that performs the final-stage dilution in the multi-stage dilution structure. The foaming agent entering the first-stage dilution chamber 502 is gradually diluted in multiple stages by the water, and is ultimately output from the mixing chamber 504. Because the water inlet structure is also connected to the final-stage dilution chamber 503, the dilution flow rate of the mixed liquid before the final-stage dilution chamber 503 can be relatively low, effectively controlling the concentration and number of foaming cycles. At the same time, water entering the final-stage dilution chamber 503 ensures a high flow rate of the final output mixed liquid, facilitating continuous foaming.

[0041] In this embodiment, the flow rate of water from the water inlet structure entering the final dilution chamber 503 is greater than the flow rate of water from the water inlet structure entering the first dilution chamber 502, so that the first dilution chamber 502 is diluted at a slow rate, avoiding the rapid discharge of liquid with high concentration in the first dilution chamber 502, thereby saving the amount of foaming agent used each time.

[0042] This embodiment further includes a mixing box 10, which is provided with a water inlet structure, a mixed liquid outlet 403, a foaming agent inlet 404, a mixing chamber 504, a plurality of dilution chambers, and a foaming agent storage chamber 505. Furthermore, the mixing box 10 includes a cover 20 and a box body 30. The cover 20 is openably connected to the upper end of the box body 30, and the cover 20 and the box body 30 enclose the mixing chamber 504, the dilution chamber, and the foaming agent storage chamber. The cover 20 is provided with a mixed liquid outlet 403 and a foaming agent inlet 404.

[0043] In this embodiment, the water inlet structure includes a water inlet chamber 501 and a water inlet 401 connected to the water inlet chamber 501. The water inlet chamber 501 is surrounded by the cover body 20 and the box body 30, and is connected to the first-stage dilution chamber 502 and the final-stage dilution chamber 503. The water inlet 401 is provided on the cover body 20; alternatively, the water inlet structure includes a water inlet pipe, which is connected to the cover body 20 and / or the box body 30 and is connected to the first-stage dilution chamber 502 and the final-stage dilution chamber 503 of the multi-stage dilution structure.

[0044] In this embodiment, it also includes an atmospheric port connected to the foaming agent storage cavity 505, which is provided on the cover body 20; it also includes a foaming agent addition port 402 connected to the foaming agent storage cavity 505, which is provided on the cover body 20, and a liquid inlet joint 70 is installed at the foaming agent addition port 402.

[0045] In this embodiment, the housing 30 is provided with a number of partitions that divide the interior of the housing 30 into a mixing chamber 504, a first-stage dilution chamber 502, a final-stage dilution chamber 503, a foaming agent storage chamber 505, and a water inlet chamber 501. The partitions are provided with connecting holes connecting the various chambers. The water flow area of ​​the through hole connecting the water inlet chamber 501 to the first-stage dilution chamber 502 is smaller than the water flow area of ​​the through hole connecting the water inlet chamber 501 to the final-stage dilution chamber 503. This ensures that the flow rate from the water inlet chamber 501 to the first-stage dilution chamber 502 is smaller than the flow rate to the final-stage dilution chamber 503. Furthermore, the water inlet chamber 501, the final-stage dilution chamber 503, and the mixing chamber 504 are arranged in parallel, with the final-stage dilution chamber 503 located between the water inlet chamber 501 and the mixing chamber 504.

[0046] The foaming flushing method for a toilet proposed in the present invention has the following working principles:

[0047] S1: The liquid pump 60 extracts a first dose of 2 ml of foaming agent from the foaming agent storage chamber 505 into the first-stage dilution chamber 502. The water inlet valve is activated to allow water to flow into the water inlet chamber 501. The water is then divided into two paths within the water inlet chamber 501: one path flows to the first-stage dilution chamber 502, and the other path flows to the final-stage dilution chamber 503. The mixed liquid in the first-stage dilution chamber 502 is pushed by the water from the water inlet chamber 501 and flows to the final-stage dilution chamber 503. The mixed liquid in the final-stage dilution chamber 503 is mixed again with the water from the water inlet chamber 501 and discharged into the mixing chamber 504. The formed foam is discharged from the mixed liquid outlet 403.

[0048] S2, the water inlet valve continues to feed water into the water inlet chamber 501, foaming the foaming agent added in the previous step multiple times, and the generated foam is discharged through the mixed liquid outlet 403. In this process, the main purpose is to generate foam, which is used to cover the water surface. Its function is to isolate odor and prevent splashing, avoid wasting foaming agent, and ensure that the foaming agent and water are evenly mixed, thereby ensuring the foaming effect.

[0049] S3. Activate the pump 60 again to pump a second dose of 8 ml of foaming agent from the foaming agent storage chamber 505 into the primary dilution chamber 502. The inlet valve is then activated to once again flow water into the inlet chamber 501. The subsequent foaming process is the same as above. This serves to discharge the foamed mixture, which has a high foaming agent content, into the water in the trap, thereby forming a bactericide. This prevents scale deposits and bacterial growth on the toilet surface caused by the water in the trap remaining in the toilet during extended periods of inactivity.

[0050] The present invention also provides a foaming system that utilizes the aforementioned foaming agent foaming process, further comprising a control device and a water inlet valve, wherein the water outlet of the water inlet valve is connected to the water inlet end of the water inlet structure, and the control device is electrically connected to the water inlet valve and the liquid pump 60. The control device activates the water inlet valve and the liquid pump 60 before the user uses the toilet or during flushing, thereby executing the aforementioned foaming process.

[0051] This embodiment also includes a timing device electrically connected to the control device. The timing device is reset and begins counting again upon activation of the foaming system. That is, each time the foaming system is activated, the timing device restarts until the foaming system is activated again. However, if the timing device reaches a preset time and the foaming system has not yet been activated, the control device automatically activates the water inlet valve and liquid pump 60 to foam, thereby replenishing the water in the water trap with a foaming mixture that has lubricating and sterilizing properties, thereby preventing bacterial growth caused by long-term non-use.

[0052] A toilet comprises a toilet body 80 and a foaming system as described above. The foaming system produces a large amount of foam that covers the toilet bowl's water cover, effectively resolving the issues of splashing and odor caused by falling excrement. Simultaneously, a timing device periodically activates the foaming system, discharging a foaming mixture containing a high foaming agent content into the water in the trap, thereby forming a bactericide. This prevents scale deposition and bacterial growth on the toilet bowl surface caused by the water in the trap remaining in the toilet bowl during immersion, which can occur after prolonged periods of inactivity.

[0053] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those skilled in the art to understand and implement the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made in accordance with the spirit of the present invention are intended to be covered by the scope of protection of the present invention.
