Flow-adjustable spray head for landscaping atomizer

Abstract

The invention discloses a flow-adjustable spray head for a landscaping atomizer. The flow-adjustable spray head comprises a liquid inlet tube, a spray head body and a spray head core, wherein a high pressure flow channel is formed in the liquid inlet tube; a swirl chamber and a first through hole are formed in the spray head body; the spray head core comprises a threaded section and a taper section; the taper section is positioned in the swirl chamber; the threaded section penetrates through the first through hole and is provided with a nut; a spray head piece is arranged at the upper part of the spray head body; a spray hole is formed in the spray head piece; a non-return ball valve is arranged at the spray hole; a compressed spring is arranged between the non-return ball valve and the taper section; and a spray head cap is arranged at the upper part of the spray head piece. The scheme has the benefits that when the flow of the spray hole needs to be adjusted, the distance between the spray head core and the spray hole is adjusted, so that the acting force of the compressed spring to the non-return ball valve is changed, and further the flow of the spray hole is adjusted; through the adoption of the scheme, on one hand, the workload of an operator can be reduced, and on the other hand, the use cost of the atomizer can be reduced.

Description

technical field [0001] The invention relates to a spray head of a sprayer, in particular to a flow-adjustable spray head for a garden greening sprayer. Background technique [0002] With the rapid development of urban construction, the requirements for landscaping are also constantly increasing. Landscaping work is inseparable from professional tools, which can fully replace human labor, save time and have high work efficiency. Plants such as trees and flowers in landscaping will inevitably be harmed by various pests and diseases during the growth process. Therefore, in order to make trees, flowers and other plants have a good growth environment, they need to be sprayed regularly Liquid medicine is used to eliminate pests and weeds, and sprayer is one of the most commonly used tools. [0003] The sprayer is a device that uses air suction to turn the liquid medicine or other liquid into a mist and sprays it evenly on other objects, and the nozzle in the sprayer is an importa...

AI Technical Summary

Problems solved by technology

[0004] The nozzle flow rate of the currently used sprayer is fixed. If you want to change the flow rate of the nozzle to meet the needs of different prevention and control work, you can only disassemble the original nozzle and replace it with a new nozzle. This will increase the number of operators. On the other hand, in order to meet the needs of different prevention and control work, a sprayer will be equipped with multiple nozzles, which will also increase the use cost of the sprayer
