The invention provides a handheld spray head, and relates to the technical field of spray heads of spraying machines. The handheld spray head is characterized by comprising a spray head cover, a flowadjusting rod, a knob cap, a vortex generator, a
water pipe and a
water pipe switching core, wherein a
spray nozzle is arranged on the top of the spray head cover, and the
tail part of the spray headcover is connected with the air
pipe, and a handheld
handle is arranged in the middle of the spray head cover; the
water pipe is arranged in the spray head cover, a water outlet of the water
pipe is connected with the vortex generator, a water inlet is connected with the water
pipe switching core, and the water pipe switching core is connected with the
drug delivery pipe in the air pipe; the flowregulating rod is connected with the vortex generator to regulate the
water flow of the water pipe, and the knob cap sleeves the flow regulating rod; and the vortex generator is arranged at the spraynozzle. According to the handheld spray head, the design of the
spray nozzle can ensure that the sprayed water mist is finer, the flow can be accurately adjusted, and the handheld spray head has the working characteristic of being suitable for ultra-low-volume
pesticide application. Furthermore, a manufacturing method of the handheld spray head is provided, and the handheld spray head is manufactured through
blow molding, and is light in weight, low in cost and compact in structure.
