Referring to fig. 1 to 3, an adjustable motorized backpack type atomizing sprayer includes a mist sprayer rack 11, a back plate 12 fixed on one side of the rack 11, and a strap 13 mounted on the back plate 12. A gasoline engine 1 is arranged on the placing rack 11, and the gasoline engine 1 comprises a gasoline pot and a gasoline engine body.
The atomizing sprayer further comprises a clutch hub 14 arranged at the output end of the gasoline engine 1, the outer side of the clutch hub 14 is connected with a fan 2, a fan front shell 22 and a fan rear shell 23 of the fan 2 are combined and fixed through screws, a centrifugal impeller 21 is arranged in the fan 2, an impeller shaft 24 penetrates through the centrifugal impeller 21, bearings 25 are respectively arranged at two ends of the impeller shaft, and the tail end of the impeller shaft 24 is clamped in the clutch hub 14; the blower rear shell 23 is provided with two air vents, namely an air inlet 26 and an air outlet 27, one end of an air pipe 3 is connected to the inside of the blower 2 through the air outlet 27, the other end of the air pipe is connected with a spray gun 4, the spray gun 4 comprises a flow regulating valve 41, and a spray head 43 is arranged on a valve seat 42 of the flow regulating valve 41; an air inlet pipe 5 is connected to the medicine box 6 from the place where the fan 2 on one side of the fan 2 is connected with the gasoline engine 1, and an infusion pipe 7 is connected to the other side of the medicine box 6 and is sprayed out from a nozzle 44 on a spray head 43 after being regulated and controlled by a flow regulating valve 41.
The utility model discloses an implementation principle as follows:
during operation, whether the liquid medicine in the medicine box 6 meets the operation requirement at the moment is checked, if not, the medicine box cover is opened, the liquid medicine or the liquid medicine amount meeting the operation requirement is poured, and then the gasoline engine 1 is started under the condition that gasoline is in the gasoline kettle.
When the gasoline engine 1 is started, a spark plug in the gasoline engine 1 ignites incoming gasoline to enter a cylinder, a piston in the cylinder pushes, a piston rod below the piston pushes a crankshaft to start rotating, the output end of the crankshaft transmits rotating force to the clutch hub 14, when a clutch switch is turned on, the rotating force at the output end of the crankshaft in the clutch hub 14 is transmitted to the impeller shaft 24 by the clutch, the impeller shaft 24 drives the centrifugal impeller 21 to rotate, and the centrifugal impeller 21 generates high-pressure and high-speed airflow in the fan 2. These flows are discharged from the discharge holes 27 into the duct 3, and then are conveyed along the wall of the duct 3 to the spray guns 4, and are ejected from the spray heads 43 through the spray guns 4. The clutch hub internal clutch structure is the basic structure of the existing clutch, and the structure of the clutch hub internal clutch structure is not changed or limited in the utility model, and the clutch is commercially available or produced by adopting the prior public technology.
At the same time, a small amount of air generated in the blower 2 is introduced into the medicine box 6 through the air inlet pipe 5, and a positive pressure is formed on the liquid surface of the medicine box 6, thereby forcing the liquid to flow into the liquid transport pipe 7 to the flow rate adjustment valve 41 and then to be atomized and discharged from the nozzle 44 on the spray head 43. At this time, when the high-pressure and high-speed air is ejected from the nozzle 43, the liquid medicine atomized and ejected from the nozzle 44 is further crushed, thinned and pushed further to expand the working range.
Compared with the existing atomizing machine, the liquid medicine has higher atomizing and refining degree, realizes the ultra-low-amount spraying and pesticide applying effect with high adhesive force of the liquid medicine, saves the liquid medicine on the whole, equivalently reduces the environmental pollution, and has stronger backpack flexibility for users.
Further, as a novel improvement of the present application, an air inlet 26 is arranged on one side of the fan 2, and a filter screen 28 is sleeved on the air inlet 26.
In this embodiment, the rotation of the centrifugal impeller 21 matched with the larger air inlet 26 can ensure that the wind pressure generated by the rotation of the centrifugal impeller 21 in the fan 2 can be output normally, and can effectively dissipate heat from the inside while keeping sucking and discharging. Thirdly, the filter screen 28 can prevent foreign matters from entering, and damage to the centrifugal impeller 21 is avoided.
Further, as a novel improvement on the present application, a liquid inlet nozzle 45 connected with a liquid delivery pipe is arranged on the inner side of the valve seat 42, and a liquid inlet channel 46 of the liquid inlet nozzle 45 is communicated with a nozzle 44 of a spray head 43 arranged on the upper surface of the valve seat 42; a flow rate adjusting knob 47 is screwed on the other side of the liquid inlet channel 46; the upper part of the valve seat 42 is fixed with a spray gun cover 48, a space 49 is left between the periphery of the valve seat 42 and the inner side cover wall of the gun cover 48, and a gas-releasing clapboard 50 is arranged on the periphery of the nozzle 44 on the upper surface of the valve seat 42.
The flow adjusting knob 47 comprises a screw cap, a screw rod arranged below the screw cap and mostly inserted into the liquid inlet channel 46, a spring sleeved on the screw rod, and a clamp limiting the spring on the screw cap and the upper half part of the screw rod.
In this embodiment, the end of the infusion tube 7 is sleeved on the liquid inlet 45, the liquid medicine is pushed by air pressure into the liquid inlet 45, flows to the nozzle 44 through the liquid inlet channel 46, and is atomized, and during the atomization, the flow adjusting knob 47 is inserted into the other side of the liquid inlet channel 46. When the flow rate adjusting knob 47 is rotated, the size of the passage between the liquid inlet passage 46 and the nozzle 44 is changed by the movement of the rotating rod, and the flow rate of the liquid medicine ejected from the nozzle 44 is controlled.
In addition, the high-pressure high-speed air flow formed by the rotation of the centrifugal impeller 21 in the fan 2 is flushed from the periphery of the valve seat 42 and the inner side cover wall of the gun cover 48 to the upper surface of the nozzle 42, and then is ejected from the periphery of the nozzle 44 to the outside through the air-permeable partition plate 50. Because the high-pressure high-speed air flow is sprayed out from the periphery of the nozzle 44, the purposes of further thinning and pushing the atomized liquid medicine farther are realized.
