[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0028] like Figure 1-3 As shown, the utility model provides an adjustable high-temperature and high-pressure steam cleaning machine, comprising a shell, and a water tank 1, a high-pressure water pump 2, a steam generating device 3, a steam jet pump 4, a steam cooler 5, a steam spray head 6, and a control device 7 arranged in the shell;

[0029] The water tank 1 is connected to a high-pressure water pump 2 on one hand, and to a steam generating device 3 on the other hand. The steam generating device 3 is connected to a steam jet pump 4 through a pipeline. The steam jet pump 4 is connected to a steam desuperheater 5. The steam desuperheater 5 is connected to a steam nozzle 6. The high-pressure water pump 2, the steam generating device 3, the steam jet pump 4, and the steam desuperheater 5 are all connected to a control device 7.

[0030] The water tank 1 and the steam desuperheater 5 are both provided with a temperature sensor 8, the water tank 1 and the nozzle of the steam jet pump 4 are provided with a pressure sensor 9, the water tank 1 is also provided with a liquid level sensor 10, a smoke density sensor 11, and a water quality sensor 12, and the temperature sensor 8, the liquid level sensor 10, the pressure sensor 9, the smoke density sensor 11, and the water quality sensor 12 are all electrically connected to the control device 7;

[0031] The control device 7 is provided with a data acquisition board, a CAN field control bus, and a control circuit board. The data acquisition board is connected to the control circuit board via the CAN field control bus. The temperature sensor 8, the liquid level sensor 10, the pressure sensor 9, the smoke sensor 11, and the water quality sensor 12 are all connected to the data acquisition board, and the data is sent to the control circuit board via the data acquisition board.

[0032] Specifically, a control panel and a display screen are disposed outside the housing, and both the control panel and the display screen are electrically connected to a control circuit board.

[0033] Specifically, a pressure reducing valve 13 is further provided at the nozzle of the water tank 1 and the steam jet pump 4, and the pressure reducing valve 13 is electrically connected to the control circuit board.

[0034] Specifically, the control circuit board is provided with a controller, a comparator, a memory, an IO interface, an AD converter, and a wireless communication module, and the comparator, the memory, the IO interface, the AD converter, and the wireless communication module are all electrically connected to the controller.

[0038] Specifically, the control circuit board is connected to the host computer and the intelligent terminal through a wireless communication module.

[0039] When the utility model is working, the steam generating device is used to heat the water in the water tank, thereby generating high-temperature steam, and the steam jet pump is used to generate high-speed airflow. The steam nozzle decompresses and speeds up the high-pressure jet steam, and converts the potential energy of the steam into kinetic energy at the steam cleaning outlet. After the high-pressure steam nozzle is throttled, the speed increases and the pressure decreases, and the high-temperature, high-pressure, and high-speed jet flows out of the nozzle, cutting and cleaning the surface, and peeling off the dirt and sediment on the surface. The utility model uses a water spray desuperheater to simultaneously adjust the steam pressure and temperature.

[0041] The utility model uses a pressure sensor to detect the pressure data at the nozzle of a water tank and a steam jet pump, and sends the collected data to a DSP digital controller through a data acquisition board. The DSP digital controller compares the collected results with a preset threshold value through a comparator. When the preset range value is exceeded, the pressure reducing valve is controlled to operate and the pressure is adjusted to avoid danger caused by high pressure. At the same time, the data is sent to a host computer and an intelligent terminal.

[0042] The utility model utilizes a liquid level sensor, a smoke density sensor, and a water quality sensor to detect the liquid level, steam concentration, and water quality data in a water tank, and sends the collected data to a DSP digital controller through a data acquisition board. The DSP digital controller compares the collected result with a preset threshold value through a comparator. When the preset range value is exceeded, an alarm is issued through the comparator, and the data is sent to a host computer and an intelligent terminal to promptly notify the staff for processing.

[0043] The utility model prevents over-cleaning and under-cleaning by detecting a series of relevant data at different times when the cleaning machine is working, and outputs the cleaning detection results after the cleaning is completed. The host computer can also judge where the fault may occur through the detection results, which is helpful to assist in judging the fault.

[0044] All matters not mentioned above are prior art.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
