Description

Technical Field

[0001] The utility model relates to the technical field of maintenance and cleaning of motor vehicle groups, in particular to a toilet pipe cleaning device. Background Art

[0002] During use, urine, alkali, scale, and other contaminants accumulate on the inner walls of the EMU toilets. This reduces the pipe's diameter, making it difficult for dirt to pass through and increasing the risk of blockage. When blocked, the toilet sewage pipes need to be cleaned to remove the contaminants and restore smooth flow.

[0003] Traditional sewage disposal operations first utilize the pneumatic backflush function of the sewer system to blow out the blockage from the toilet bowl and clean it out; then manually adjust the control valve in the pipeline to isolate the sewer pipe and the sewage tank, and connect the pipeline between the toilet bowl and the wash basin; finally, pour an acidic detergent at around 60°C from the wash basin into the pipeline system until the detergent overflows from the toilet bowl. After soaking for a period of time, the detergent in the pipeline is discharged into the sewage tank, and the entire cleaning operation is completed.

[0004] However, this sewage discharge method has the following problems:

[0005] (1) The cleaning method is single, the cleaning time is long, and it requires a lot of manpower. The current sewage pipeline cleaning is completely done manually, which is not very effective in cleaning the pipeline dirt.

[0006] (2) The solution cools quickly and the cleaning effect is poor. Acidic cleaning agents will dissolve urea alkali more effectively at around 60°C, and the solution will dissipate heat quickly through the metal pipe during cleaning.

[0007] (3) The cleaning solution is in a static state and can only dissolve and remove scale locally, and other high-position pipes cannot be effectively cleaned; the concentration of the static cleaning effective substance will become uneven as the amount of dissolved urea increases.

[0008] Market Status: Research indicates that there are specialized equipment on the market for cleaning EMU toilet pipes, but these are trolley-type devices used under the train, making them inconvenient to use. Currently, there are no dedicated onboard equipment for cleaning EMU toilet pipes on the market. Utility Model Content

[0030] Example 1

[0031] like Figure 1-Figure 3 As shown, the utility model provides a toilet pipe cleaning device, including a liquid storage tank 1, which is provided with a liquid return port 2; a heating device 4 is provided on one side of the liquid storage tank 1, and the liquid storage tank 1 is connected to a liquid supply port 5 through the heating device 4; a filtering device 6 is provided on one side of the liquid storage tank 1, and the liquid return port 2 is connected to a filter inlet 7 through the filtering device 6. The liquid storage tank 1 is provided with a liquid injection port 3.

[0032] Specifically, the liquid storage tank 1 uses a 20L sprayer as the shell and carrier, and is provided with a liquid injection port 3 and a liquid return port 2 on the top. The water source is directly 60°C hot water. Citric acid powder is added and stirred to dissolve. After dissolution, it is injected into the liquid storage tank 1 through the liquid injection port 3.

[0033] Because the sewage pipeline has multiple check structures, the cleaning liquid circulates in an external loop, cleaning the sewage pipeline through circulation. The heated citric acid solution is discharged from the liquid storage tank 1 along the pipeline from the liquid supply port 5 (hot solution outlet) to the wash basin 12, flows along the drain of the wash basin 12 until it flows out of the sewage outlet of the toilet collection tank 13, filling the sewage pipeline of the toilet collection tank 13 with the solution; at the same time, the filter inlet 7 is connected to the pipeline 11 and leads to the cleaning liquid sucked out of the toilet collection tank 13 (via the return liquid pump 9), which is filtered by the filter device 6 and then enters the liquid storage tank 1 through the return liquid port 2. The circulation ensures the constant temperature of the liquid in the sewage pipeline and the constant concentration of citric acid, improving the cleaning effect of the pipeline dirt.

[0034] The citric acid solution is heated by the heating device 4 in the pipe 11 from the liquid storage tank 1 to the liquid supply port 5. The heating device 4 continuously heats the solution discharged from the liquid supply port 5 and outputs the heated cleaning liquid (citric acid solution) to the hand washing sink 12, keeping the solution at about 60°C during the cleaning process to maintain the cleaning effect.

[0035] The heating device 4 is provided on one side of the liquid storage tank 1, and the liquid supply port 5 is provided at the upper end of one side of the liquid storage tank 1. The heating device 4 can be, for example, an electric heating tube (the solution passes through the tube, and the electric heating wire is wrapped around the outside of the tube to heat the solution in the tube). This flow heating structure is common in the prior art, and its structural principle will not be described in detail.

[0036] Filter device 6 is disposed at the bottom of liquid storage tank 1, with filter inlet 7 positioned on one side of the bottom. Refluxing solution enters filter device 6 through filter inlet 7, is filtered, and then passes through pipeline 11 into liquid return port 2, where it is returned to liquid storage tank 1. A pipe can be connected to filter device 6, extending to the side of liquid storage tank 1. During use, a steel hose connects the pipe of filter device 6 to liquid return port 2. Filter device 6, such as a filter with a mesh structure, is readily available and its structural principles are not further described.

[0037] Example 2

[0038] A liquid supply pump 8 and a liquid return pump 9 are provided on one side of the liquid storage tank 1. The liquid supply pump 8 is connected to the liquid supply port 5, and the liquid return pump 9 is connected to the filter inlet 7 or the liquid return port 2. The flow rate of the liquid return pump 9 is greater than that of the liquid supply pump 8. A flow regulating valve (not shown) is installed at the outlet of the liquid supply pump 8.

[0039] Specifically, the liquid supply pump 8 uses a miniature DC submersible pump for water supply. It features strong resistance to solid impurities, high flow rate, low head, pressure holding capability, easily adjustable flow rate, and a compact size. The pump is powered by a safe 24V DC power supply and is submerged directly within the water tank, eliminating the need for external space. The flow rate of the pump is controlled by adjusting the valve opening, which is installed directly at the outlet. The specific water supply pump selected is a submersible pump, model NC50A-1250, DC12V, MAX1.9A, head 5m, static flow rate 13.5L / min, and maximum power 22.8W. One unit is required.

[0040] The return pump 9 uses a diaphragm pump for negative pressure suction, featuring strong resistance to solid impurities, strong self-priming ability, pressure holding capability, and acid and alkali resistance. The return pump is a diaphragm pump, model L0742H2D-12-100F, DC12V10A, 100W, 7L / min, with a suction range of 1.5m. Two units are required (if space is limited, two smaller pumps can be arranged in parallel).

[0041] A speed regulator 801 is designed on the liquid supply pipeline 11 to control the water outlet speed of the liquid supply pump 8 (submersible pump) and control the return liquid flow of the return liquid pump 9 to be greater than the liquid supply flow of the liquid supply pump 8, so that the suction flow is greater than the liquid supply flow, ensuring that the cleaning liquid at the toilet collection tank 13 will not overflow.

[0042] Example 3

[0043] The system further includes a control device 10, which is in signal communication with the heating device 4, the filtering device 6, the liquid supply pump 8, and the liquid return pump 9. A liquid level switch 101 is provided in the liquid storage tank 1, and a temperature sensor 401 is provided on the heating device 4. Both the liquid level switch 101 and the temperature sensor 401 are in signal communication with the control device 10.

[0044] Specifically, the control device 10 is arranged on the outside of one side of the liquid storage tank 1, and specifically includes a housing, a power adapter 1001, a control circuit (including a timing switch 1002, a temperature control switch 1003, a power adjustment module 1004), a display screen 1005 and buttons. This controller mainly realizes the control function through a PLC module, which is common in the prior art, and its structural principle is not repeated in this embodiment. The control device 10 includes temperature control adjustment, circulation speed adjustment, time control, etc. The heating device 4, the filtering device 6, the liquid supply pump 8 and the liquid return pump 9 are connected to the control device 10 through electrical signals or wireless network signals; the liquid level switch 101 and the temperature sensor 401 are connected to the control device 10 through electrical signals or wireless network signals.

[0045] The circuits and waterways are arranged separately and centrally, with the circuits arranged on the upper side of the waterways. However, water splashing is inevitable during use. To prevent water from entering the circuits, a guide plate is used in the control device 10 to completely isolate the high-voltage circuits during design. Even if water enters the housing of the control device 10, it will not touch the high-voltage circuits.

[0046] A liquid level switch 101 is designed in the liquid storage tank 1. When the citric acid solution is insufficient and lower than the required liquid level, the liquid level sensor is activated, and the control device 10 receives a signal to automatically power off each system. At the same time, a temperature sensor 401 is designed at the outlet of the electric heating tube. When the temperature is higher than the set temperature, the control device 10 receives a signal to automatically power off each system, and the outlet temperature switch closes the circuit to prevent dry burning.

[0047] Example 4

[0048] The liquid supply port 5 is connected to a spherical bottom valve (not shown) via a pipe 11, located at the drain outlet of a wash basin 12. The filter inlet 7 is also connected to a cylindrical bottom valve (not shown) via a pipe 11, located below the step of a toilet bowl 13. The filter device 6 is connected to the liquid return port 2 via a pipe 11, which is a steel hose.

[0049] Specifically, the main body of the pipeline 11 is designed with a steel wire reinforced hose. When bent, the pipeline 11 can maintain a good diameter, and there will be no dead bends or crushing at various parts, thus avoiding the problem of pipeline 11 being blocked.

[0050] Since the citric acid solution is added at the wash basin position during use, which is inconvenient to fix, this embodiment uses a stainless steel spherical internal thread bottom valve connected to the liquid supply port 5 through the pipeline 11. On the one hand, it can be placed well in the wash basin by its own weight. At the same time, the spherical head porous water outlet also effectively reduces the impact of the water outlet and avoids water overflow. Since the return water position is the toilet 13 (squatting toilet), the outlet is circular and has steps. A stainless steel cylindrical internal thread bottom valve is selected, which can be inserted into the air and stood on the steps. Water overflowing above the steps can be sucked away in time.

[0051] Working mode and principle of this device:

[0052] Citric acid powder is added to the water source and stirred to dissolve. After dissolution, it is injected into the liquid storage tank 1. The citric acid solution in the liquid storage tank 1 is discharged from the liquid storage tank 1 along the pipeline 11 (not shown, the citric acid solution is heated by the heating device 4 during the flow of the pipeline 11) from the liquid supply port 5 (hot solution outlet) to be added to the wash basin 12 (via the liquid supply pump 8). It flows along the drain of the wash basin 12 until it flows out of the sewage outlet of the toilet collection tank 13, so that the solution fills the sewage pipe of the toilet collection tank 13. At the same time, the filter inlet 7 is connected to the pipeline 11 and receives the cleaning liquid sucked out of the toilet collection tank 13 (via the liquid return pump 9). After being filtered by the filter device 6, it enters the liquid storage tank 1 through the liquid return port 2.

[0053] This device has light tooling, simple equipment structure and low cost; it has a circulating cleaning function to ensure the concentration of effective substances in the cleaning liquid in the pipeline, and will not reduce the concentration and affect the descaling ability due to the consumption of effective substances; it has heating and temperature maintenance functions to improve the cleaning effect of the cleaning agent in the pipeline; the water inlet flow can be adjusted according to actual needs to achieve circulating self-balancing.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
