[0029] Example 1:
[0030] like Figures 1 to 7 , a backpack electric sprayer integrated control module is installed on the electric sprayer housing 10, including a controller panel 20 and a controller circuit board 30.
[0031] The controller circuit board 30 is fixedly mounted with a charging port 31, an on / off switch 32, a speed regulator 33, and an indicator light 34. The charging port 31 is a 24V DC charging port, the on / off switch 32 is a two-position on / off switch, the speed regulator 33 is equipped with a speed regulator shaft 35, and the indicator light 34 is an LED. The charging port 31, on / off switch 32, speed regulator 33, and indicator light 34 are welded to the controller circuit board 30, forming an integrated controller functional module. The controller circuit board 30 also features a cable port 39 for connecting the electrical components within the electric sprayer.
[0032] Corresponding to the controller circuit board 30 , the controller panel 20 is provided with a charging port opening 21 , a switch key opening 22 , a speed regulator opening 23 and an indicator light opening 24 .
[0033] The controller panel 20 is provided with a circuit board mount 25. When the controller panel and the controller circuit board are assembled, the controller circuit board 30 is inserted into the mount 25. The speed regulator shaft 35 passes through the speed regulator opening 23 and extends out of the controller panel 20. The speed regulator shaft 35 has mounting threads 37, which are supported by a mounting nut 38. When tightened, the mounting nut 38 presses against the controller panel 20, securing the controller circuit board thereto. A speed control knob 36 is provided at the protruding end of the speed regulator shaft.
[0034] The electric sprayer housing 10 is provided with a control module opening 11, which is a single rectangular opening. A controller panel 20 is mounted on the control module opening. Two ends of the control module opening are provided with latches 12, and two ends of the controller panel 20 are provided with first mounting tabs 26, which are used to mount the controller panel on the control module opening.
