Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0024] See also Figures 1 to 3 The utility model provides a technical solution: a high-temperature steam cleaning machine, comprising a shell 1, a steam tank 9, a water inlet valve 11, and a booster pump 7 are fixed on the bottom surface of the shell 1, the water inlet valve 11 is connected to a water source, the water inlet valve 11 is connected to the booster pump 7, the water outlet of the booster pump 7 is connected to the steam tank 9, the water source is passed into the booster pump 7 by the water inlet valve 11, and then the booster pump 7 overcomes the pressure of the steam tank 9 and pumps the water into the steam tank 9, and by heating the water in the steam tank 9, steam is generated in the steam tank 9 to increase the pressure of the steam tank 9. The upper end of the steam tank 9 is connected to a steam outlet tee 95, one end of which is connected to a pressure gauge 4, through which the internal pressure of the steam tank 9 is detected, and the other end is connected to a steam solenoid valve 6, which controls the on-off of the steam pipeline, and the end of the steam solenoid valve 6 is connected to an external water pipe 2, and the other end of the external water pipe 2 is connected to a spray gun 3, which is arranged on the outer surface of the shell 1. By opening the steam solenoid valve 6, the steam can flow along the external water pipe 2 to the spray gun 3 and be sprayed from the spray gun 3;

[0025] A bypass pipe 21 is also connected to the external water pipe 2, and the other end of the bypass pipe 21 is connected to an air source. An air source solenoid valve 22 is connected between the bypass pipe 21 and the air source. After steam cleaning is completed, the steam solenoid valve 6 is closed and the air source solenoid valve 22 is opened to allow compressed air to enter the spray gun 3 to clean the water droplets condensed by the steam on the surface of the instrument, thereby reducing the drying process. At the same time, the spray gun 3 can also clean the remaining condensed water droplets in the cleaning pool, thereby reducing the growth of bacteria.

[0026] like Figure 3 As shown, two control buttons 31 are provided on the spray gun 3, and the two control buttons 31 are respectively connected to the steam solenoid valve 6 and the air source solenoid valve 22. The two control buttons 31 respectively control the on and off of the steam solenoid valve 6 and the air source solenoid valve 22, and further control the medium in the spray gun 3, so that the spray gun 3 can use steam for cleaning and compressed air for processing condensed water droplets.

[0027] like Figure 4 As shown, the steam tank 9 includes an upper tank 91 and a tank base 92. A through hole is opened in the center of the bottom of the tank base 92 for connecting with the booster pump to pump water into the steam tank 9. An upper flange 93 is welded to the bottom of the upper tank 91, and a lower flange 94 is welded to the upper end of the tank base 92. The upper flange 93 and the lower flange 94 are connected by fasteners. An electric heating plate 96 is arranged on the bottom of the tank base 92. A temperature control switch 10 is connected to the side of the upper tank 91. The electric heating plate 96 is connected to the temperature control switch 10. By designing a split steam tank 9, it is convenient to disassemble the upper tank 91 and the tank base 92 to separate the two, which is further convenient for repairing and replacing the internal electric heating plate 96 or cleaning the scale on the inner wall.

[0028] A drain valve 97 is connected to the lower end of the tank base 92. By opening the drain valve 97 when the steam tank 9 is in a high-pressure state, the gas and liquid in the steam tank 9 are discharged from the drain valve 97 using the pressure, thereby flushing and cleaning the dirt in the tank base 92.

The first liquid level probe 98 and the second liquid level probe 99 extend into the upper tank 91. The lengths of the first liquid level probe 98 and the second liquid level probe 99 are inconsistent. The length of the first liquid level probe 98 is greater than the length of the second liquid level probe 99. The lower end of the first liquid level probe 98 is lower than the lower end of the second liquid level probe 99. The two liquid level probes are connected to the booster pump 7 at the same time, and the operation of the booster pump 7 is controlled by the height of the liquid level. When the liquid level is lower than the lower end of the first liquid level probe 98, the booster pump 7 will operate to pump water into the steam tank 9. When the liquid level contacts the lower end of the second liquid level probe 99, the booster pump 7 will stop operating, thereby realizing automatic water addition to the steam tank 9.

[0031] A display screen 5 is also installed on the shell 1, and the display screen 5 is used to display the parameters in the steam tank 9. A pressure transmitter is also connected to the top of the steam tank 9. The pressure transmitter converts the physical pressure parameters of gas, liquid, etc. sensed by the pressure measuring element sensor into a standard electrical signal, which is convenient for real-time understanding of the parameters of the equipment.
