Description

[Technical Field]

[0001] This invention relates to the field of motor technology, and in particular to a mist spray motor. [Background Technology]

[0002] Mist sprayers are generally used to spray corrosive liquids such as pesticides. Since the motor parts contain metal materials, if pesticides enter the motor, the magnets, stator and rotor plates, enameled wires, etc. inside the motor will be corroded, and even the electrical control parts will be corroded, leading to damage to the entire power unit.

[0003] For pesticides to be sprayed, the motor needs to rotate at high speed. Waterproofing the high-speed rotating motor shaft with the stationary, non-rotating parts is a challenging technical task.

[0004] Excessive tightness between stationary components and the motor shaft will prevent the motor output shaft from rotating or cause significant energy loss, resulting in severe overheating and energy waste. Since drones use mobile power supplies as their energy source, energy is extremely precious during use. Excessive energy consumption will severely limit the overall battery life of the device.

[0005] If the waterproofing is too loose, pesticides will enter the motor and corrode the motor and electrical control components. After a few days or hours of use, the mist spray motor will be corroded and damaged, resulting in a very short lifespan for the device.

[0006] Therefore, existing technologies have shortcomings and need to be improved. [Summary of the Invention]

The motor shaft 12 drives the spray disc 50 to rotate. The nozzle pipe 30 connects to a pesticide tank. Liquid pesticide is pumped to the nozzle pipe 30 and then enters the honeycomb disc 40 and the spray disc 50. The honeycomb disc 40 and the spray disc 50 rotate at high speed, spraying the liquid pesticide in a mist, allowing for wide-area pesticide application to crops. Both the honeycomb disc 40 and the spray disc 50 have a honeycomb tooth structure, which disperses the liquid into a mist when the spray disc 50 rotates at high speed. The spray disc 50 is fixedly connected to the motor shaft 12 with screws.

[0031] The nozzle tube 30 is provided with an overflow port 331, which is used to overflow excess liquid and prevent liquid from entering the motor body 10.
