Spray nozzle

Abstract

The invention discloses a spray nozzle. The spray nozzle comprises a spray nozzle body, wherein a liquid inlet end is arranged at one end of the spray nozzle body; a liquid outlet end is arranged at the opposite end of the spray nozzle body; a cavity communicated with the liquid outlet end and the liquid inlet end respectively is formed inside the spray nozzle body; an inclined plane is arranged on the outer side surface, near the liquid inlet end thereof, of the spray nozzle body; the included angle between the inclined plane and the axis of the liquid inlet end is an acute angle; a plurality of drainage holes are formed in the inclined plane and are communicated with the cavity inside the spray nozzle body respectively. Through arrangement of the inclined spray nozzle body as well as the drainage holes, forming a radial shape, arranged on the spray nozzle body at intervals, the spray nozzle can provide a high enough spraying pressure; the flow of liquid entering the spray nozzle body is enlarged through the drainage holes to enlarge the outflowing amount of the liquid at the liquid outlet end of the spray nozzle, so that the spray nozzle has a very high spraying amount and a very high spraying force, and thus the quality of an electroplated product is improved; particularly, the spray nozzle can provide great help when a workpiece hole is relatively deep.

Description

technical field [0001] The invention relates to a nozzle, which is mainly used in the field of electroplating. Background technique [0002] When working in the field of electroplating surface treatment, the flow rate, spray angle and spray direction of the nozzle during electroplating have a great influence on the effect of electroplating. Currently, the nozzles used are as attached figure 1 , 2 As shown, one end of the nozzle body 1 is provided with a liquid inlet port 2, and the opposite end is provided with a nozzle outlet port 3, a cavity 4 is provided inside the nozzle body, and a thread 6 is provided on the liquid inlet end of the nozzle, It is fixedly installed on the electroplating solution delivery pipeline through thread 6. After the electroplating solution is transported to the nozzle by the electroplating solution delivery pipeline, the liquid inlet end of the nozzle flows through the cavity inside the nozzle body to the liquid outlet end, thereby realizing th...

Problems solved by technology

However, due to the limitation of the injection force of the nozzle, only good surface uniformity and large gushing flow can be obtained, which makes the chemical solution in the deep hole unable to be renewed, resulting in insufficient copper in the electroplating field, affecting the workpiece Processing quality, severe cases lead to product scrapping
