[0027] like Figure 1 , Figure 2 and Figure 3 As shown, an on-vehicle disinfection system provided in an embodiment of the present application includes a control cabinet 1 and a high-pressure pump assembly module, a fuel heater assembly module 6 and a temperature control tank assembly 7 electrically connected to the control cabinet 1.

[0028] It also includes a high-pressure cleaning unit 2, a low-pressure cleaning unit 3 and a first pipeline. The high-pressure pump assembly module includes a water pump 4 and a water tank 5 responsible for containing the water output of the water pump 4. The water outlet of the water tank 5 is connected to the fuel heater assembly module 6 through a first pipeline. The fuel heater 604 is provided with a first water outlet and a second water outlet.

The thermostat assembly 7 is connected to the low-pressure cleaning unit 3 through a fourth pipeline.

[0029] The water tank 5 is provided with a first return water interface 501 and a second return water interface 502, the first pipeline is provided with a plunger pump 10 and a plunger pump 10 pressure regulating valve, the plunger pump 10 pressure regulating valve is connected to the first return water interface 501 through a pipeline to form a first return water circuit 18, the thermostatic tank assembly 7 module includes a thermostatic tank 701, the thermostatic tank 701 is provided with an overflow port, the overflow port is connected to the second return water interface 502 through a pipeline to form a second return water circuit 17, and the second return water circuit 17 is provided with a No. 1 check valve 702 to prevent water from flowing back into the thermostatic tank 701.

[0031] During operation, the high-pressure pump assembly module delivers water to the fuel heater assembly module 6. After the water is heated in the fuel heater 604, a part of the water flows to the second pipe through the first water outlet, flows to the temperature regulating tank 701 through the water inlet 7011 of the temperature regulating tank after passing through the second pipe, and flows to the low-pressure cleaning unit 3 through the fourth pipe from the water outlet 7012 of the temperature regulating tank.

[0038] In the above design, the pressure of the temperature regulating tank 701 can be sensed in time by setting the pressure transmitter 703. By setting the electric actuator 704, when the pressure transmitter 703 senses that the pressure of the temperature regulating tank 701 is too high, the electric actuator 704 controls the second water return circuit 17 to operate.

[0039] Specifically: Figure 1 As shown, the control cabinet 1 also includes a plunger pump motor frequency converter 16 connected to the plunger pump 10 , and the control cabinet 1 controls the plunger pump 10 by controlling the plunger pump motor frequency converter 16 .

[0041] Specifically: the first return water channel 18 is provided with a No. 2 flow meter 13 for detecting the flow rate on the first return water channel 18, the first pipeline is provided with a No. 1 flow meter 12 for detecting the amount of water flowing from the water tank 5 into the heater 604, a water flow switch 14 for controlling the water flow and a temperature detector 15 for detecting the water flow temperature, and the No. 1 flow meter 12, the No. 2 flow meter 13, the water flow switch 14 and the temperature detector 15 are all connected to the control cabinet 1.

[0043] Specifically: Figure 3 As shown, the heater 604 is provided with a steam pressure relief port 6041 , and the temperature regulating tank 701 is provided with a water discharge port 7013 .

[0044] In the above design, by providing the steam pressure relief port 6041 and controlling the opening and closing of the pressure relief port, the pressure in the heater 604 can be released or maintained.

[0045] Specifically: the control cabinet 1 is also provided with a liquid level switch interface of the oil tank 602 and a liquid level switch interface of the water tank 5 .

[0046] In the above design, by setting the liquid level switch interface of the oil tank 602 and the liquid level switch interface of the water tank 5, the control cabinet 1 can control the liquid level of the oil tank 602 and the liquid level of the water tank 5.
