[0002] Currently, the methods for cleaning various vehicles and equipment mainly include manual cleaning and cleaning by a cleaning machine. Among them, manual cleaning has the disadvantages of being time-consuming and laborious, and having poor cleaning effects. Therefore, this method is generally not used unless necessary. The cleaning machine using water as the cleaning medium is widely used for cleaning various vehicles and equipment because it does not require manual cleaning and has good cleaning effects.

[0003] The main structure of the cleaning machine using water as the cleaning medium includes an electric booster pump, a water gun, etc. During operation, the water source input from the outside is pressurized by the booster pump and ejected from the front end of the water gun, so as to achieve the purpose of high-pressure flushing of equipment or vehicles. Since the existing cleaning machines all use water as the cleaning medium, the water consumption is large, resulting in waste of water resources. Moreover, since the electric booster pump of the existing cleaning machine needs to use electricity and water is used during the cleaning process, serious personal injuries are likely to occur in case of electric leakage. Summary of the Invention

[0004] In order to overcome the disadvantages of the existing cleaning machine using water as the cleaning medium, such as water waste and the risk of electric shock to the cleaning personnel due to its structure limitations, the present invention provides an ultra-high-speed air flow cleaning equipment that does not use electricity at all, will not have electric shock accidents, uses compressed air as the carrier for water atomization and water pressure change. During application, the air flow and the water flow act on the surface of the article to be cleaned at the same time. The air flow and the water flow can simultaneously promote the dirt on the surface of the article to peel off and be washed away by water, and the use density of water is reduced, so as to achieve water conservation and better cleaning effects.

The water inlet end of the pneumatic diaphragm pump 3 and the water outlet pipe 52 at the lower rear end of the middle part of the water tank 5 are connected by a pipeline and a pipeline joint. The water outlet end of the pneumatic diaphragm pump 3 and the third end of the second three-way pipe 91 are connected by a hose; the pneumatic booster pump 6 is installed at the front end of the water tank 5 and is located above the pneumatic diaphragm pump 3 through screw nuts. The exhaust pipe of the pneumatic booster pump 6 and the air inlet pipe of the pneumatic diaphragm pump 3 are connected by a pipeline joint; the filter 4 is installed at the rear side of the pneumatic pressure regulating valve 7 through screw nuts; the third end of the first three-way pipe 72 and the air inlet pipe of the filter 4 are threadedly connected. The exhaust pipe of the filter 4 and the air inlet pipe of the pneumatic booster pump 6 are connected by a pipeline and a pipeline joint; the pneumatic air control valve 8 supporting the pneumatic pressure regulating valve is installed at the front left end of the water tank 5. The two operating handles 81 of the pneumatic air control valve 8 are located at the front outer side end of the upper cover of the machine body.

[0016] Figure 1 , 2As shown, the outside of the machine body has a detachable outer shell 102. A sealing cover is installed at the upper end of the water inlet pipe 51 of the water tank. There are several ventilation holes on the sealing cover (to ensure that no negative pressure is generated in the water tank 5), and the water tank 5 is filled with water. The upper side end of the exhaust pipe of the pneumatic booster pump 6 is installed with a pressure gauge 61 through a pipe. The rear side end of the intake pipe 71 of the pneumatic pressure regulating valve is installed with a pressure gauge 73 through a pipe. The upper ends of the dials of the two pressure gauges are located outside the middle of the upper cover of the machine body. At the upper middle part of the rear end of the machine body 1, a pusher 103 is welded. The spray gun 2 and the hose 21 connected to the spray gun are located outside the machine body 1, and the hose 21 has a relatively long length. The air compressor model is 3KW-30L, brand Yilu'an; the spray gun 2 is an ordinary water spray gun; the pneumatic diaphragm pump 3 model is TX25 ANN-7HP (Tapflo brand); the filter 4 model is AW20-02BCE-B (SMC brand); the pneumatic booster pump 6 model is VBA10A-F02GN (SMC brand); the water tank 5 is made of stainless steel metal; the pneumatic pressure regulating valve 7 model is VEX1700-12 (SMC brand); the pneumatic air control valve 8 model is VPA342-1-01A (SMC brand).

[0017] Figure 1 、 2As shown in the figure, in the application of the present invention, the compressed air output by the air compressor (with a pressure of about 0.6 - 0.8 MPa) enters the pneumatic pressure regulating valve 7 through the air inlet pipe 71 of the pneumatic pressure regulating valve. After being divided by the first three-way joint 72, the compressed air enters the main pipeline 9 (with a pressure of about 0.3 - 0.4 MPa), the spray nozzle 10, and the pneumatic booster pump 6 respectively (the compressed air first passes through the filter 4 and then enters the pneumatic booster pump 6, with a pressure of about 0.1 - 0.15 MPa). Under the action of its internal mechanism, the pneumatic booster pump 6 doubles the air pressure (with a pressure of 0.2 - 0.3 MPa) and then enters the pneumatic diaphragm pump 3. After the pneumatic diaphragm pump 3 works, under the action of its internal mechanism, the water in the water tank is pressurized and output into the spray nozzle 10 (the air inlet pipe pressure of the pneumatic diaphragm pump 3 is high, the water outlet end pressure of the pneumatic diaphragm pump 3 is high and the water volume is large; the air inlet pipe pressure of the pneumatic diaphragm pump 3 is low, the water outlet end pressure of the pneumatic diaphragm pump 3 is low and the water volume is small). Then the water and the compressed air in the spray nozzle 10 converge, and the water vapor mixture flowing through the spray gun hose 21 is instantly cavitated at the outlet of the spray gun 21 to form a water mist. The water and the compressed air are simultaneously sprayed onto the surface of the item to be cleaned through the nozzle of the spray gun 2. The pressure when reaching the spray gun outlet is about 0.3 - 0.4 MPa, and then it is transported to the surface to be cleaned to achieve the cleaning effect. In the actual operation of the present invention, a cleaning agent can be mixed into the water tank 5 to enhance the cleaning effect. Micro-particle abrasives with a diameter less than 0.5 mm can be added to the water tank 5 to enhance the impact force and improve the impact force, which can be used to clean stubborn stains and even achieve paint stripping and rust removal. In the present invention, the user can adjust the flow rate of the exhaust pipe of the pneumatic pressure regulating valve 7 by adjusting the adjusting handle 81 of the pneumatic control valve 8, so as to adjust the amount of compressed air entering the main pipeline 9 and the pneumatic booster pump 6. When the valve core of the pneumatic pressure regulating valve 7 is opened to a large extent, the air flow rate entering the main pipeline 9 and the pneumatic booster pump 6 increases, and the ratio of water to compressed air becomes larger. When the valve core of the pneumatic pressure regulating valve 7 is opened to a small extent, the air flow rate entering the main pipeline 9 and the pneumatic booster pump 6 decreases, and the ratio of water to compressed air becomes smaller. In this way, by adjusting the different ratios of water and air when they are mixed, the atomization effect of the cleaning water can be adjusted to achieve different cleaning effects. Since there is no power input in the present invention, it can achieve good safety effects. In the application, the air flow and the water flow act on the surface of the item to be cleaned at the same time. The air flow and the water flow can simultaneously promote the dirt on the surface of the item to peel off and be washed away by the water, and the usage density of the water is reduced, so as to achieve water saving and better cleaning effects. 11 is the supporting adjustment valve switch of the pneumatic diaphragm pump 3. If the switch of the pneumatic diaphragm pump is turned off, only compressed air comes out of the spray gun 2. After it is opened, air and water are mixed and sprayed out. 12 is the emergency stop switch. During the use of the emergency stop switch 12, by controlling the air control valve 8, the valve core of the pneumatic pressure regulating valve 7 is opened and closed to zero, thereby closing all air circuits.
