The electric push rod 902 is fixedly connected to the inside of the recess. The pressurizing pipe 903 is fixedly connected to the front side of the sealing cover 805. The pressurizing pipe 903 is fixedly connected with a suction pipe 904 at the bottom end. The one-way valve assembly one is arranged inside the front end of the pressurizing pipe 903. The one-way valve assembly two is arranged inside the bottom of the suction pipe 904. The piston 905 is slidingly connected inside the pressurizing pipe 903. The piston 905 is fixedly connected with a piston rod 906 at the rear side. The connecting rod 907 is rotationally connected between the tail end of the piston rod 906 and the front end of the electric push rod 902.

[0055] The one-way valve assembly one includes a filter plate one 908, a connecting pipe one 911, a sealing plate one 912, a spring one 913 and a sealing ring one 914. The filter plate one 908 is fixedly connected inside the pressurizing pipe 903. The filter plate one 908 is fixedly connected with a limiting pipe one 909 at the rear side. The limiting pipe one 909 is fixedly connected with a square shaft one 910 inside. The connecting pipe one 911 is slidingly connected inside the limiting pipe one 909.

[0061] When the connecting rod 907 drives the piston rod 906 and the piston 905 to slide to the tail end of the pressurizing pipe 903, negative pressure is generated in the pressurizing pipe 903. The diluted liquid medicine extrudes the sealing plate two 919 to separate from the sealing ring two 921, so that the liquid medicine can flow into the extraction pipe 904.

[0062] When the connecting rod 907 drives the piston rod 906 and the piston 905 to slide to the front end of the pressurizing pipe 903, high pressure is generated in the pressurizing pipe 903. The diluted liquid medicine extrudes the sealing plate one 912 to separate from the sealing ring one 914, so that the diluted liquid medicine flows into the hose 2 through the filter plate one 908, sprays out the water mist through the atomizing nozzle 6, and sprays the plant.

[0063] When it is necessary to adjust the single spraying amount, the electric push rod 902 is only needed to be started to stretch out and retract, the electric push rod 902 stretches out and retracts, the distance between the first end of the electric push rod 902 and the driving shaft of the motor 801 can be adjusted, the radius distance when the first end of the electric push rod 902 operates is adjusted, the distance when the piston 905 slides back and forth is adjusted, the adjustment of the extraction amount and the spraying amount is completed, the inside of the electric push rod 902 drives the displacement sensor, the length of the electric push rod 902 can be monitored in real time, and the length of the electric push rod 902 can be read by the receiver at the far end.

[0064] The displacement sensor is an existing product on the market, and the connection mode and control method thereof are prior art, and details are not repeated here.

[0065] The electrical elements appearing in the text are all connected with the master controller and 220V mains, and the master controller can be a conventional known device such as a computer for control, and the detailed description of known functions and known components is omitted in the specific embodiment of the disclosure, and in order to ensure the compatibility of the device, the operation means adopted is consistent with the parameters of the equipment on the market.
