Description

TECHNICAL FIELD

[0001] The utility model relates to liquid force shower head technical field especially points to a liquid force type atomizing shower head of ducted fan wind delivery. BACKGROUND

[0002] At present, the liquid force type atomizing shower head has poor controllability of mist droplets and wide particle size spectrum, and when the helicopter is used for pesticide application, the mist droplets are easily affected by the wing tip vortex and wind field entrainment, resulting in the phenomenon that the mist droplets are entrained and drifted. In order to reduce the influence of wind on the sprayed pesticide during spraying, the conventional method is to pressurize the pesticide during spraying. The existing pressurized spraying device basically uses air pressurization to pressurize the pesticide, but the pesticide will contain more air after air pressurization. During spraying, the normal operation of the pump body is affected, and the uniformity during spraying is affected.

[0003] The Chinese invention patent with publication number CN115672589A discloses a plant protection unmanned aerial vehicle anti-drift atomizing shower head, which comprises a connecting pipe and a shower head end communicated with the connecting pipe. A wind-breaking airflow protection cover is rotatably connected outside the connecting pipe. A wind direction adapting assembly is fixedly installed outside the wind-breaking airflow protection cover. A wind sleeve is fixedly installed outside the connecting pipe. An air inlet pipe is communicated with the top of the wind-breaking airflow protection cover. The plant protection unmanned aerial vehicle anti-drift atomizing shower head uses the cooperation of the V-shaped groove and the flow channel to semi-enclose the atomized liquid sprayed from the shower head end with the gas sprayed from the horn cover. Under the setting of the wind direction adapting assembly, the hollow ring drives the horn cover to rotate and aligns with the direction of the incoming wind, effectively ensuring the windproof effect of the atomized liquid. Since the air outlet area of the V-shaped groove and the flow channel is small, the gas protection strength is higher under the same pressure.

[0004] In this scheme, high-pressure air is used to form a wind force protection cover to reduce the influence of the sprayed pesticide mist on the unmanned aerial vehicle. However, the scheme uses remote air supply, which requires the unmanned aerial vehicle to carry an air compressor to continuously produce air. The pesticide spraying process relies on the use of the air compressor on the unmanned aerial vehicle, which will reduce the effective load of the unmanned aerial vehicle. Therefore, the reliability is not high, and the practicality is not strong. UTILITY MODEL CONTENTS

[0023] The present nozzle does not need to be provided with a remote air supply end, and the ducted fan is directly matched with the nozzle to produce wind, which avoids the complex remote air supply related components and structure, reduces the load of the unmanned aerial vehicle, and is more practical and reliable.

[0024] As a further embodiment, the cylindrical shell 1 includes an upper shell 11 and a lower shell 12, the upper shell 11 and the lower shell 12 are connected by socket and locked by bolts, and the ducted fan 2 is detachably arranged in the upper shell 11.

[0025] Specifically, in the present embodiment, the upper shell and the lower shell are both cylindrical shells, coaxially arranged, and provided with matching socket structures at opposite ends, and corresponding threaded holes or through holes are provided, and connected and locked by bolts threaded in the threaded holes or through holes.
