Effervescent atomization medicament applying spray head

Abstract

The invention relates to an effervescent atomization medicament applying spray head, which comprises a spray head body, a spray sheet, a pipe joint and a spray head cap, and is characterized in that a contraction cavity, a laryngeal cavity and an expansion cavity are arranged in an inner cavity of the spray head body, wherein a bubble generator is arranged in the spray head body, a liquid inlet hole is arranged on one side of the spray head body, the lower end of the spray head body is connected with the spray head cap, a seal ring is arranged between the lower end of the spray head body and the spray head cap, the bubble generator is linked with the spray head body through a gas inlet pipe joint, gas injection holes which are in staggered spatial arrangement are arranged at the tail end of the bubble generator, the spray sheet is embedded in the spray head cap, a spray sheet pressure block is arranged above the spray sheet, the spray sheet pressure block is in tight fit with the spray head cap, and a liquid inlet pipe is linked with the spray head body through a liquid inlet pipe joint. Compared with the prior art, the effervescent atomization medicament applying spray head has the advantages of improving the applicability to medicament liquid with different viscosities of the plant protection spray head, enabling fog drops to be finer and more uniform, and having better atomization effect.

Description

Technical field [0001] The invention belongs to a planting protection spraying device, in particular to a bubble atomized spraying spray nozzle. Background technique [0002] The sprinkler is a key component of the plant protection application equipment, which directly affects the application effect of the equipment. At present, the widely used pressure atomizing nozzles and pneumatic atomizing nozzles rely on the large relative speed difference between the atomizing medium and the liquid, which mainly overcomes the viscosity of the liquid to atomize the liquid. The required atomization pressure is large and the viscosity The bigger it is, the harder it is to atomize. The pressure atomizing nozzle uses the pressure of the liquid itself as the kinetic energy to atomize the liquid medicine. The structure is simple and the cost is low, but its atomization effect is greatly affected by the load and pressure reduction, and the droplet penetration is poor, and the droplet size is affe...

AI Technical Summary

Problems solved by technology

The pressure atomization nozzle uses the pressure of the liquid itself as kinetic energy to atomize the liquid medicine. It has a simple structure and low cost, but its atomization effect is greatly affected by the load drop, and the droplet penetration is poor, and the droplet size is affected by the liquid. The viscosity has a great influence; although the atomization performance of the pneumatic atomizing nozzle is better than that of the pressure atomizing nozzle, its atomization consumes a lot of air and energy
