Technical Field

[0001] The utility model belongs to the technical field of water supply sanitation systems for rail transit vehicles, in particular to a toilet flushing device suitable for rail vehicles. Background Art

[0002] The existing rail vehicles, especially the railway passenger car water supply and sanitation system is an important system for providing passengers with toilets. Toilet flushing requires automatic water replenishment, and the water inlet and flushing are controlled by valves. In the case of long-term use, the valve may become stuck and water will flow for a long time, which will cause the toilet to leak and flood the car. In addition, its self-assessment function of the usage status is poor. With the development of technology and the continuous improvement of intelligent needs, a toilet flushing device suitable for rail vehicles is needed. Utility Model Content

[0005] The first air supply device is used to provide pressure for flushing the toilet;

[0006] The first solenoid valve is used to control the first air supply device to supply air to the water tank and is in a normally closed state. When the toilet needs to be flushed, the control panel controls the first solenoid valve to open;

[0007] The water supply device is used to provide a water source;

[0008] The water inlet valve is used to control the water supply device to supply water to the water tank, and is in a normally closed state. When the water tank needs to be replenished with water, the control panel controls the water inlet valve to open;

[0020] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a toilet flushing device suitable for rail vehicles of the utility model in conjunction with the accompanying drawings.

[0021] Reference Figure 1 The whole device mainly consists of a first air supply device 1, a first solenoid valve 2, a vent valve 3, an exhaust port 4 outside the vehicle, a water supply device 5, a water inlet valve 6, a water tank 7, a liquid level sensor 8, a control panel 9, a flushing button 10, a second air supply device 11, a second solenoid valve 12, a flushing valve 13, and a toilet 14. The control panel 9 connects the first solenoid valve 2, the water inlet valve 6, the liquid level sensor 8, the flushing button 10 and the second solenoid valve 12. The first solenoid valve 2 and the vent valve 3 are installed between the air supply device 1 and the water tank 7, and are connected through an air pipe. The water inlet valve 6 is installed between the water supply device 5 and the water tank 7, and are connected through a water pipe. The second solenoid valve 12 is installed between the air supply device 11 and the flushing valve 13, and are connected through an air pipe. The flushing valve 13 is installed between the water tank 7 and the toilet 14, and are connected through a water pipe.

[0022] The first air supply device 1 is used to provide pressure for toilet flushing.

[0023] The first solenoid valve 2 is used to control the air supply device 1 to supply air to the water tank 7 and is in a normally closed state. When the toilet needs to be flushed, the control panel 9 controls the first solenoid valve 2 to open.

[0024] The vent valve 3 is used to switch between supplying air to the water tank 7 and ventilating to the exhaust port 4 outside the vehicle. When the toilet needs to be flushed, the air supply passes through the vent valve 3 and, under the action of wind pressure, is conducted to the water tank 7; when the water tank 7 is replenished with water, the first solenoid valve 2 is closed, and the water tank 7 is conducted to the exhaust port 4 outside the vehicle.

[0025] The vehicle exterior exhaust port 4 is used to exhaust the water tank 7 to the outside of the vehicle. At the same time, when the water inlet valve 6 is abnormally closed and the water supply device 5 continues to supply water to the water tank 7, excess water is discharged to the outside of the vehicle through the vehicle exterior exhaust port 4 to prevent overflow into the vehicle.

[0026] The water supply device 5 is used to provide water.

[0027] The water inlet valve 6 is used to control the water supply device 5 to supply water to the water tank 7, and is in a normally closed state. When the water tank 7 needs to be replenished with water, the control panel 9 controls the water inlet valve 6 to open.

[0028] The water tank 7 is used to temporarily store the flushing water of the toilet.

[0029] The liquid level sensor 8 is used to detect the water level status in the water tank 7 and is located at the top of the water tank 7. When the water level in the water tank 7 does not reach the height of the liquid level sensor 8, the liquid level sensor 8 does not output a liquid level signal to the control board 9, and the control board 9 controls the water inlet valve 6 to open and replenish water to the water tank 7; when the water level in the water tank 7 reaches the height of the liquid level sensor 8, the liquid level sensor 8 outputs a liquid level signal to the control board 9, and the control board 9 controls the water inlet valve 6 to close and stop replenishing water to the water tank 7.

[0030] The control panel 9 is used to control the operation of the toilet flushing device. When the flush button 10 is triggered, the control panel 9 controls the first solenoid valve 2 and the second solenoid valve 12 to open, the flush valve 13 to open, and the water in the water tank 7 flushes the toilet 14 under pressure. When the liquid level sensor 8 does not detect the water level signal, the water inlet valve 6 is controlled to open to replenish the water tank 7. If the water inlet valve 6 is opened for more than the specified time, the liquid level sensor 8 continues to fail to detect the water level signal, and the control panel 9 feedbacks the toilet flushing device failure information. When the liquid level sensor 8 detects the water level signal, the water inlet valve 6 is controlled to close and stop replenishing water. If the control panel 9 does not issue a toilet flushing instruction, the liquid level sensor 8 changes from detecting the water level signal to not detecting the water level signal, and the control panel 9 feedbacks the toilet flushing device failure information. When the liquid level sensor 8 detects the water level signal, from the beginning to the end of the toilet flushing instruction issued by the control panel 9, the liquid level sensor 8 has always had a water level signal, and the control panel 9 feedbacks the toilet flushing device failure information.

[0031] The flush button 10 is used for passengers to control the flushing of the toilet.

[0032] The air supply device 11 is used to provide an air source for opening and closing the flushing valve 13 .

[0033] The second solenoid valve 12 is used to control the opening and closing of the flushing valve 13 .

[0034] The flush valve 13 is used to control the opening and closing of the water tank 7 to the toilet 14. It is in a normally closed state and is opened when the toilet needs to be flushed. The water in the water tank 7 flushes the toilet 14 under the action of wind pressure.

[0035] The toilet 14 is used for passengers to use the toilet.
