Based on the flush button signal, the toilet system is controlled to flush, and the flush button indicator light flashes at a first set frequency. If the flush button signal is received for a second set duration after the self-flushing button signal disappears, the water supply and sanitation system is reset, and the flush button indicator light flashes at a second set frequency for a third set duration.

[0015] The pressurization device provided by this invention mainly consists of a first pressurizer and a second pressurizer. The first and second pressurizers have the same structure. The water circuits of the first and second pressurizers are connected in parallel, and the air circuits of the first and second pressurizers are also connected in parallel.

[0024] In embodiments of the present invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0026] The turbocharger mainly consists of a housing and an elastic component. The housing has a cavity inside, and a vent 320 and a liquid inlet 310 that communicate with the cavity. Air can enter and exit the cavity through the vent 320, and liquid can enter and exit the cavity through the liquid inlet 310. The elastic component is set inside the cavity and is transversely separated between the vent 320 and the liquid inlet 310. It is equivalent to dividing the cavity on both sides of the elastic component into an air cavity and a liquid cavity. The elastic component can elastically deform in the cavity, thereby changing the volume of the air cavity and the liquid cavity.

[0027] As the elastic component deforms, it can switch between a first state and a second state within the cavity. In the first state, air enters the air cavity through the vent 320, and the air cavity pressure gradually increases, driving the elastic component to deform in the direction of the liquid inlet 310, compressing the space of the liquid cavity. Therefore, in the first state, the volume of the air cavity gradually increases, and the volume of the liquid cavity gradually decreases, with the liquid inside the liquid cavity being discharged outward through the liquid inlet 310. In the second state, liquid enters the liquid cavity through the liquid inlet 310, and the liquid cavity pressure gradually increases, driving the elastic component to deform in the direction of the vent 320, compressing the space of the air cavity. Therefore, in the second state, the volume of the liquid cavity gradually increases, and the volume of the air cavity gradually decreases, with the air inside the air cavity being discharged outward through the vent 320.

[0028] like Figures 1 to 2As shown in the figure, an embodiment of the present invention provides a booster device, including a first booster 100 and a second booster 200. The liquid inlet 310 of the second booster 200 is connected in parallel with the liquid inlet 310 of the first booster 100, and the air outlet 320 of the second booster 200 is connected in parallel with the air outlet 320 of the first booster gas.

[0029] The pressurization device of this invention mainly consists of a first pressurizer 100 and a second pressurizer 200. The first pressurizer 100 and the second pressurizer 200 have the same structure. The water circuits of the first pressurizer 100 and the second pressurizer 200 are connected in parallel, and the air circuits of the first pressurizer 100 and the second pressurizer 200 are connected in parallel. Water is first injected into the liquid chambers of the first pressurizer 100 and the second pressurizer 200 through the liquid inlet 310, and then the water injection stops. When the toilet is flushed, air is injected into the air chambers of the first pressurizer 100 and the second pressurizer 200 through the air inlet 320. The air chambers gradually increase in size, pressing against the liquid chambers and causing the liquid chambers to gradually decrease in size. The water in the liquid chambers of the first pressurizer 100 and the second pressurizer 200 is discharged through the liquid inlet 310 and collected to flush the toilet.

[0030] In this invention, the first booster 100 is the original booster, and the second booster 200 is a newly added booster. There can be one or more second boosters 200, each with the same structure, and all are connected in parallel with the first booster 100 in both water and air circuits. Therefore, this invention does not involve opening new molds or adding new accessories. While keeping spare parts unchanged, by connecting multiple boosters in parallel with their air and water circuits, water can be simultaneously pressurized and supplied to the liquid chambers of the boosters. Furthermore, multiple boosters can simultaneously drain water, increasing the flushing volume, improving the flushing effect, and solving the problem of ceramic toilets being difficult to flush away tea leaves and other foreign objects. When applied to toilets in rail vehicles and EMUs, this invention utilizes a parallel multi-stage boosting method to increase the flushing volume, effectively improving the toilet's flushing effect and saving on modification time and costs.

[0031] In this embodiment, the volume of both the first turbocharger 100 and the second turbocharger 200 is 0.8L.

[0032] According to one embodiment of the present invention, the booster device further includes an inlet valve 400, the outlet of the inlet valve 400 being connected to the inlet 310 of the first booster 100 via a main inlet pipe 410, and the inlet 310 of the second booster 200 being connected to the main inlet pipe 410 via a branch inlet pipe 420.

[0033] In this embodiment, the booster device mainly consists of a first booster 100, a second booster 200, and an inlet valve 400. The main liquid pipe 410 includes a first pipe section 411, a second pipe section 412, and a third pipe section 413. The first pipe section 411 and the second pipe section 412 are used to inject water into the booster and are connected sequentially along the direction of water flow from the water source into the liquid chamber. The second pipe section 412 and the third pipe section 413 are used to drain water from the booster and are connected sequentially along the direction of water flow from the liquid chamber into the toilet. An inlet valve 400 is provided on the first pipe section 411. The second pipe section 412 is connected to the liquid inlet 310 of the first booster 100. An interface is provided on the second pipe section 412. One end of the branch liquid pipe 420 is connected to the interface, and the other end is connected to the liquid inlet 310 of the second booster 200. The third pipe is connected to the toilet.

[0034] The inlet valve 400 is a one-way valve. When the inlet valve 400 is open, the water source enters through the first pipe section 411 and then enters through the inlet valve 400 into the second pipe section 412 and the branch pipe 420 to inject water into the first booster 100 and the second booster 200. When the first booster 100 drains water, it can only flow into the third pipe section 413 through the second pipe section 412. When the second booster 200 drains water, it flows into the second pipe section 412 through the branch pipe 420. The water flow from the second booster 200 and the drainage from the first booster 100 can only flow into the third pipe section 413, thus avoiding backflow.

[0035] In this embodiment, a filter 430 is also provided on the first pipe section 411. The water from the water source first flows through the filter 430 and then flows through the inlet valve 400. The filter 430 filters the water entering the booster to prevent impurities in the water from causing pipe blockage, ensuring the safe use of the booster and the flushing effect of the booster device.

[0036] According to one embodiment of the present invention, the booster device further includes a liquid outlet valve 500, the liquid outlet valve 500 being connected to the liquid inlet 310 of the first booster 100 via a main liquid inlet pipe 410, and the liquid inlet 310 of the second booster 200 being connected to the main liquid inlet pipe 410 via a branch liquid inlet pipe 420.

[0037] In this embodiment, the pressurizing device mainly consists of a first pressurizer 100, a second pressurizer 200, an inlet valve 400, and an outlet valve 500. The outlet valve 500 is installed on the third pipe section 413. When the toilet needs to be flushed, the outlet valve 500 opens when the first pressurizer 100 and the second pressurizer 200 drain water. The water from the first pressurizer 100 can only flow into the third pipe section 413 through the second pipe section 412, and the water from the second pressurizer 200 flows into the second pipe section 412 through the branch pipe 420. The water from the second pressurizer 200 merges with the drainage from the first pressurizer 100 and can only flow into the third pipe section 413. After passing through the outlet valve 500, the water from the third pipe section 413 flows into the toilet.

[0038] The outlet valve 500 can be a flow valve, which can adjust the water flow rate in the third pipe section 413, thereby controlling the water flow rate and the amount of water discharged.

[0039] According to one embodiment of the present invention, the booster device further includes an intake valve 600, which is connected to the air inlet 320 of the first booster 100, the air inlet 320 of the second booster 200 and the liquid outlet valve 500 respectively through an air supply pipe 610.

[0040] In this embodiment, the booster device mainly consists of a first booster 100, a second booster 200, an inlet valve 400, an outlet valve 500, and an air inlet valve 600. The air supply pipe 610 includes a fourth pipe section 611, a fifth pipe section 612, and a sixth pipe section 613. The fourth pipe section 611 is used to connect the air source to the air inlet 320 of the first booster 100, the fifth pipe section 612 is used to connect the fourth pipe section 611 to the air inlet 320 of the second booster 200, and the sixth pipe section 613 is used to connect the fifth pipe section 612 to the air inlet of the outlet valve 500. The gas source supplies gas to the air chamber of the first booster 100 through the fourth pipe section 611. The gas can also flow from the fourth pipe section 611 into the fifth pipe section 612, and supply gas to the air chamber of the second booster 200 through the fifth pipe section 612. It can also flow from the fifth pipe section 612 into the sixth pipe section 613, and supply gas to the liquid outlet valve 500 through the sixth pipe section 613.

[0041] The outlet valve 500 is a pneumatically controlled valve. When the air source supplies air to the first booster 100 and the second booster 200, the outlet valve 500 opens pneumatically, thus enabling drainage from the first booster 100 and the second booster 200. An air inlet valve 600 can be installed on the fourth pipeline. The air inlet valve 600 can be a pneumatic solenoid valve. When the toilet is flushed, the pneumatic solenoid valve is energized and opens to supply air, pressurizing the two boosters for drainage. Simultaneously, the outlet valve 500 opens, and the two pressurized water streams converge to flush the toilet, increasing the total flush volume from 1.2L / flush to 1.6L / flush.

[0042] The waste collection system provided by the present invention is described below. The waste collection system described below can be referred to in correspondence with the pressurization device described above.

[0043] This invention also provides a waste collection system, including a pressurizing device and a toilet as described in the above embodiments, wherein the toilet is connected to the outlet of the liquid outlet valve 500 of the pressurizing device.

[0044] The toilet system controller (with a built-in reset button) of the EMU is installed in the power distribution cabinet at the end of the carriage, or the toilet system controller is integrated into the network system control and directly cancels the toilet system controller. The reset button is set on the control panel in the mechanic's room. When the toilet malfunctions, the onboard mechanic has to run to the end power distribution cabinet or the mechanic's room to operate the reset button. The operation is inconvenient and cannot quickly eliminate the fault.

[0045] The control method of the waste collection system provided by the present invention is described below. The control method of the waste collection system described below can be referred to in correspondence with the waste collection system described above.

[0046] like Figure 3 As shown, this embodiment of the invention also provides a control method for a waste collection system, applied to the waste collection system as described in the above embodiments, comprising: Determine if the water supply and sanitation system has a disabled fault, and obtain the pulse width of the flush button signal; If the pulse width of the flush button signal meets the first signal condition, the water supply and sanitary system is reset.

[0047] The control method of the waste collection system in this embodiment of the invention can perform input detection and fault detection simultaneously after the waste collection system is powered on, reset, or in standby mode. Input detection includes flush button signal detection. First, it is determined whether a water supply sanitary system is disabled. If so, the pulse width of the flush button signal is obtained. Then, it is determined whether the pulse width of the flush button signal meets the first signal condition. If so, the water supply sanitary system is controlled to reset.

[0048] When the water supply and sanitation system of this vehicle malfunctions, the habit of resetting it locally and nearby is retained. Pressing the flush button will trigger the flush button signal. By detecting the triggering status of the flush button signal, the pulse width of the flush button signal can be obtained. The type of flush button signal can be distinguished by the relationship between the pulse width and the first signal condition, that is, it is determined whether the obtained flush button signal is a reset signal. Different modes of flush button control can be realized. Thus, by operating the flush button, the water supply and sanitation system can be easily and quickly reset when it malfunctions.

[0049] In this embodiment, it is first determined whether a water supply and sanitation system disabling fault has occurred. If so, fault detection and alarm are triggered. At the same time, the pulse width of the flush button signal is acquired, and it is determined whether the pulse width of the flush button signal meets the first signal condition. If not, the pulse width of the flush button signal is acquired again.

[0050] According to one embodiment of the present invention, determining that the pulse width of the flush button signal satisfies a first signal condition, and controlling the water supply sanitary system to reset includes: The flush button signal is determined to disappear for a first set duration, and the flush button signal is continuously acquired. If the flush button signal is received for a second set duration after the self-flushing button signal disappears, the water supply and sanitation system is reset, and the flush button indicator light flashes at a second set frequency for a third set duration.

[0051] In this embodiment, the specific steps for determining that the pulse width of the flush button signal meets the first signal condition and controlling the water supply and sanitation system to reset include: firstly, determining whether the disappearance time of the flush button signal lasts for a first set duration; if so, continuously acquiring the flush button signal; then determining whether the time for continuously acquiring the flush button signal after the disappearance of the flush button signal lasts for a second set duration; if so, controlling the water supply and sanitation system to reset, and the flush button indicator light flashes at a second set frequency for a third set duration.

[0052] The first signal condition includes two aspects: firstly, the flush button signal is paused for a duration greater than or equal to a first set time; secondly, after the signal pauses, the flush button signal is received again, and the continuous triggering time of the flush button signal is greater than or equal to a second set time. In this embodiment, the first set time is 1 second, and the second set time is 30 seconds. That is to say, after the flush signal disappears for 1 second and is triggered again for 30 seconds, the water supply and sanitation system is reset. The reset function of the water supply and sanitation system can be achieved by pressing and holding the flush button.

[0053] In this embodiment, the third set duration is 5 seconds and the second set frequency is 2Hz. That is, during the reset of the water supply and sanitation system, the flush button indicator light flashes at a frequency of 2Hz for 5 seconds.

[0054] In this embodiment, before continuously acquiring the flush button signal after determining that the disappearance time of the flush button signal lasts for a first set duration, the method further includes determining whether the flush button signal has been triggered. If so, the fault display and alarm are maintained; if not, the method further determines whether the disappearance time of the flush button signal lasts for the first set duration.

[0055] After determining that the disappearance time of the flush button signal lasts for a first set duration, first check whether the flush button signal has been triggered. If so, then check whether the time for receiving the flush button signal has lasted for a second set duration. If not, continue checking whether the flush button signal has been triggered.

[0056] According to one embodiment of the present invention, the control method for the waste collection system further includes: Confirm that there are no disabled faults in the water supply and sanitation system, and obtain the pulse width of the flush button signal; If the pulse width of the flush button signal meets the second signal condition, the water supply and sanitation system will issue a toilet unavailable alarm.

[0057] In this embodiment, it is determined whether a water supply and sanitation system malfunction has occurred. If not, the pulse width of the flush button signal is obtained, and then it is determined whether the pulse width of the flush button signal meets the second signal condition. If so, the water supply and sanitation system is controlled to issue a toilet unavailable alarm.

[0058] When there is no disabled fault in the vehicle's water supply and sanitation system, pressing the flush button will trigger the flush button signal. By detecting the triggering status of the flush button signal, the pulse width of the flush button signal can be obtained. The type of flush button signal can be distinguished by the relationship between the pulse width and the second signal condition, that is, whether the obtained flush button signal is a flush signal or a button contact sticking fault signal. Different modes of flush button control can be realized. Thus, by operating the flush button, the water supply and sanitation system can be conveniently and quickly alarmed and flushed when there is no fault in the water supply and sanitation system.

[0059] According to one embodiment of the present invention, determining that the pulse width of the flush button signal satisfies a second signal condition, and controlling the water supply sanitation system to issue a toilet unavailable alarm includes: The flush button signal is received, and the toilet system is controlled to flush. The flush button indicator light flashes at a first set frequency. The system determines that the flush button signal is received for a second set duration, and then controls the water supply and sanitation system to issue a toilet unavailable alarm.

[0060] In this embodiment, the specific steps for determining that the pulse width of the flush button signal meets the second signal condition and controlling the water supply and sanitation system to issue a toilet unusable alarm include: firstly, acquiring the flush button signal, controlling the waste collection system to flush, and having the flush button indicator light flash at a first set frequency; then, determining whether the time for acquiring the flush button signal lasts for a second set duration; if so, controlling the water supply and sanitation system to issue a toilet unusable alarm.

[0061] The second signal condition is that after the flush button signal is triggered, the trigger time of continuously receiving the flush button signal is greater than or equal to the second set duration. In this embodiment, the second set duration is 30 seconds. That is, after the flush signal trigger starts and lasts for 30 seconds, the water supply and sanitation system is controlled to issue a toilet unusable alarm. The toilet unusable alarm function of the water supply and sanitation system can be realized by pressing and holding the flush button.

[0062] In this embodiment, the first set frequency is 1Hz, that is, during the flushing process of the toilet by the waste collection system, the flush button indicator light flashes at a frequency of 1Hz.

[0063] In this embodiment, after confirming that the water supply and sanitation system has no disabled faults, it first determines whether the flush button signal is triggered. If so, it controls the toilet system to flush, and the flush button indicator light flashes at a first set frequency. If not, it then determines whether the flush signal disappearance time is a continuous first set duration. If not, it continues to determine whether the flush button signal is triggered.

[0064] In this embodiment, it is determined whether the time for obtaining the flush button signal lasts for a second set duration. If not, it is determined whether the flush button signal is triggered.

[0065] According to one embodiment of the present invention, the control method for the waste collection system further includes: If the pulse width of the flush button signal meets the third signal condition, the water supply and sanitary system is reset.

[0066] In this embodiment, if it is determined that no disable fault has occurred in the water supply and sanitation system, the pulse width of the flush button signal is obtained, and then it is determined whether the pulse width of the flush button signal meets the third signal condition. If so, the water supply and sanitation system is controlled to reset.

[0067] When there is no fault in the vehicle's water supply and sanitation system, pressing the flush button will trigger the flush button signal. By detecting the triggering status of the flush button signal, the pulse width of the flush button signal can be obtained. The type of flush button signal can be distinguished by the relationship between the pulse width and the satisfaction of the third signal condition, that is, it can be determined whether the obtained flush button signal is a flush signal or a reset signal, so as to realize different modes of control of the flush button. Thus, by operating the flush button, the water supply and sanitation system can be easily and quickly reset and flushed when there is no fault.

[0068] According to one embodiment of the present invention, determining that the pulse width of the flush button signal satisfies a third signal condition, and controlling the reset of the water supply sanitary system includes: The flush button signal is determined to disappear for a first set duration, and the flush button signal is continuously acquired. Based on the flush button signal, the toilet system is controlled to flush, and the flush button indicator light flashes at a first set frequency. If the flush button signal is received for a second set duration after the self-flushing button signal disappears, the water supply and sanitation system is reset, and the flush button indicator light flashes at a second set frequency for a third set duration.

[0069] In this embodiment, the specific steps for determining that the pulse width of the flush button signal meets the third signal condition and controlling the water supply and sanitation system to reset include: firstly, determining whether the disappearance time of the flush button signal lasts for a first set duration; if so, continuously acquiring the flush button signal; then, based on the flush button signal, controlling the toilet system to flush; the flush button indicator light flashes at a first set frequency; then, determining whether the time for acquiring the flush button signal lasts for a second set duration; if so, controlling the water supply and sanitation system to reset; the flush button indicator light flashes at a second set frequency for a third set duration.

[0070] The third signal condition includes two aspects: firstly, the flush button signal is paused for a duration greater than or equal to the first preset duration; secondly, after the signal pauses, the flush button signal is received again, and the continuous triggering time of the flush button signal is greater than or equal to the second preset duration. In this embodiment, the first preset duration is 1 second, and the second preset duration is 30 seconds. That is to say, after the flush signal disappears for 1 second and is triggered again for 30 seconds, the water supply and sanitation system is reset. The reset function of the water supply and sanitation system can be achieved by pressing and holding the flush button.

[0071] In this embodiment, the second set frequency is 2Hz and the third set duration is 5 seconds. That is, during the reset process of the water supply and sanitation system, the flush button indicator light flashes at a frequency of 2Hz for 5 seconds.

[0072] In this embodiment, it is determined whether the disappearance time of the flush button signal lasts for a first set time. If so, it continues to determine whether the flush button is triggered. If the flush button is triggered, the toilet system is controlled to flush, and the flush button indicator light flashes at a first set frequency. Then, it is determined whether the flush signal trigger time lasts for a second set time. If so, the water supply and sanitation system is controlled to reset, and the flush button indicator light flashes at a second set frequency for a third set time. Then, it returns to input detection and fault detection.

[0073] In this embodiment, it is determined whether the flush button is triggered. If so, the determination continues. It is also determined whether the time for which the flush button signal is received lasts for a second set duration. If not, the determination continues.

[0074] If no faults occur in the water supply and sanitation system, when the flush button remains on for 30 seconds, repeatedly performing flushing actions within that timeframe, while the flush button indicator light flashes at a frequency of 1Hz, the flushing process is complete after 30 seconds. The flush button indicator light then turns off, and the mechanic's console displays fault codes 00 and 08, along with a TCMS "Toilet Unavailable" alarm. If the flush button is detected to have been off for 1 second or more, and remains on for 30 seconds, repeatedly performing flushing actions within that timeframe, while the flush button indicator light flashes at a frequency of 1Hz, the flushing process is complete after 30 seconds. After the final flush, the water supply and sanitation system is reset, and the flush button indicator light begins flashing at a frequency of 2Hz for 5 seconds.

[0075] This invention optimizes the toilet flushing control logic while maintaining the original flush button structure. It distinguishes between flushing signals, reset signals, and button contact sticking fault signals using the trigger signal pulse width, achieving self-reset, self-diagnosis, and multi-mode control functions. When a toilet malfunctions, the system can quickly restart and reset, aiming for rapid fault elimination. Utilizing the flush button located within the bathroom, only software modifications are needed to implement the toilet flush button reset function, improving fault handling efficiency.
