Technical Field

[0001] The present application relates to the field of spraying devices, and in particular to a handheld electric sprayer. Background Art

[0002] A sprayer is a machine that disperses liquid into a mist. It is a type of machinery that can be used for agricultural, medical, and other purposes (such as industrial). Agricultural applications are classified as agricultural machinery and plant protection machinery. Human-powered sprayers are generally called sprayers, while those powered by power (engines, electric motors) are called sprayers. Sprayers are categorized by their operating principle as hydraulic, pneumatic, and centrifugal. They are also categorized by their portability, including handheld, backpack, shoulder, pedal, stretcher, cart, self-propelled, vehicle-mounted, and suspended. Aerial sprayers are also available.

[0003] The fans of existing sprayers are mostly located inside the spray tube or the body of the sprayer. The water mist sprayed by the sprayer usually contains a large amount of corrosive components. The power output device of the fan is corroded by the mist for a long time, which makes the fan easily damaged and shortens the service life of the sprayer. At the same time, the existing spray tube can usually only adjust the spray intensity by simply controlling the power of the fan or the power of the internal atomizing mechanism during spraying, and the adjustment effect is poor. Utility Model Content

The nozzle is located inside the mist guide tube body. The water pump draws the liquid medicine from the liquid storage tank and introduces it into the nozzle pipe. The nozzle pipe and the first atomizing nozzle hole atomize the liquid medicine. The rotation of the fan generates wind that blows the liquid medicine from the air guide tube body into the mist guide tube body, blowing the atomized liquid medicine from the mist guide tube body out. This prevents the fan from being corroded by the liquid medicine, thereby improving the service life of the device.

[0020] 2. By moving the lever and rotating it on the slide, the cover plate can be rotated by turning the lever to change the position of the cover plate. When the position of the cover plate changes, the overlapping area of ​​the second atomizing nozzle and the first atomizing nozzle also changes, thereby changing the size of the mist sprayed by the water pump from the overlapping area, achieving the effect of quickly and easily adjusting the spray distance of the spray device.
