[0002] The traditional high-pressure car washing machine water gun automatic controller stop gun shutdown device, when the car washing machine is working, the water gun valve is closed, the water flow will become smaller or stop, the water pressure in the water outlet channel rises sharply, which will cause the overflow valve to work, drive the micro switch to turn off the motor, and realize the automatic shutdown function of the car washing machine. When the water gun valve is opened, the water gun discharges water, the water pressure in the water outlet channel drops, the overflow valve is closed, and the micro switch is driven to turn on the motor, realizing the automatic start function of the car washing machine.

[0003] During the assembly or use of the overflow valve, damage to the O-ring or combined seal ring, or loosening of the mounting screws or pipe joints may cause the car washer to malfunction. After the water pump stops working, the water in the water pipe will flow back to the overflow valve, causing impact on it and affecting the service life of the water pump. To this end, we provide an electronic controller for a high-pressure car washer to solve the above problems. To this end, we provide an automatic gun stop and shutdown device for a car washer to solve the above problems. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0023] like Figure 1-3 As shown, the utility model provides a technical solution: an automatic gun stopping and shutting down device for a car washing machine, comprising a car washing machine body, a receiving end 5 and a transmitting end 6.

[0024] The car washing machine body includes a car washing pump 1 and a water gun 4. A U-shaped pipe 2 is installed at the output end of the car washing pump 1. A connecting pipe 3 is fixedly connected to the U-shaped pipe 2, and the end of the connecting pipe 3 away from the U-shaped pipe 2 is installed on the water gun 4. The U-shaped pipe 2 is designed to be U-shaped, which can retain the water that flows back from the connecting pipe 3 to the U-shaped pipe 2 in the U-shaped pipe 2, thereby preventing the water from flowing back into the car washing pump 1 and shortening the service life of the car washing pump 1.

[0025] The transmitting end 6 is installed on the water gun 4, and an antenna 7, a battery 9, a switch 10, a Bluetooth IC 11 and a key module 12 are arranged in the transmitting end 6. The switch 10 is installed in the transmitting end 6, and the switch 10 is electrically connected to the Bluetooth IC 11. The timing module 13 is installed in the transmitting end 6, and the timing module 13 is electrically connected to the key module 12.

[0026] When the button module 12 is pressed, it can trigger a signal to the Bluetooth IC-11. The Bluetooth IC-11 also serves as the main control processor. The internal MCU of the Bluetooth IC-11 processes the signal of the button module 12, and enables the Bluetooth IC-11 to complete the signal transmission and reception through the antenna-7. The timing module 13 can complete the timing operation, that is, the current car washing time is counted. After the time reaches the predetermined value, a closing signal is sent to the Bluetooth IC-11 through the button module 12.

[0027] The receiving end 5 is installed on the car washing pump 1. The receiving end 5 is provided with a power supply component, a Bluetooth IC 2 14, a Bluetooth 2 15 and a control module 16. The power supply component includes a voltage stabilizing module 18 and an AC module 17.
