Description
Technical Field
The utility model relates to the technical field of ultrasound, in particular to an ultrasonic spray head structure with an ultrasonic anti-blocking function.
Background
The ultrasonic spraying is to atomize the liquid flowing through the working end of the ultrasonic transducer by utilizing the capillary wave atomization function generated by ultrasonic waves to generate micron-sized fine liquid drops, homogenize and crush the mist particles under the action of air flow after introducing gas with proper pressure, and simultaneously drive the mist particles to run and guide the running direction of the mist particles by the air flow, thereby achieving the purpose of realizing the precise spraying on the surface of an object to be coated.
Ultrasonic spraying generally involves feeding a liquid or a solid-liquid mixture through a liquid delivery tube or a liquid inlet needle to the working end face of an ultrasonic transducer, and atomizing the liquid into fine particles by high-frequency vibration of the working end face of the transducer. Generally, in the process of micro-flow or low-flow infusion, after liquid or a solid-liquid mixture flows through a liquid inlet needle through a pipeline, the liquid forms deposition in the liquid inlet needle or the pipeline due to the slow flow rate, so that blockage is caused. In addition, when the liquid supply works for a period of time temporarily, the liquid at the mouth of the liquid inlet needle is easy to block because the liquid is crystallized, separated and deposited after contacting with air. In addition, some viscous liquid or solid-liquid mixture exists, and the phenomenon of liquid flow blockage is caused because the inner hole of the liquid inlet needle is very thin and the surface is rough and not smooth and is easily scraped with solid small particles in the mixture.
In order to solve the problems, the traditional method for preventing the solid deposition in the pipeline generally adopts a mechanical vibration mode to drive the whole infusion pipeline to vibrate, so that the liquid is uniformly mixed and prevented from being deposited, the liquid at the mouth part of the liquid inlet needle needs to be manually wiped and sucked dry, and the residual crystallization at the mouth part is prevented; the inner hole of the liquid inlet needle is polished to be smooth by adopting a polishing process, so that the friction resistance is reduced.
However, the above-mentioned method for preventing the deposition of solids in pipes has at least the following disadvantages:
1) the deposition of a part of solid particles can be reduced through the mechanical vibration of the pipeline, but the mechanical vibration causes the fatigue of the pipeline connecting part, and meanwhile, the vibration of the pipeline can cause the rapid and slow surging of the liquid in the pipeline, so that the liquid flow is not uniform;
2) the liquid inlet needle opening is manually wiped, so that the liquid inlet needle is extremely easy to touch excessively, the liquid inlet needle is displaced if the liquid inlet needle is light, liquid inlet deviation is caused, and the liquid inlet needle is bent, deformed and scrapped if the liquid inlet needle is heavy;
3) if the inner hole of the liquid inlet needle is polished, the process is difficult, and particularly for a capillary needle with an extremely fine inner hole, the capillary needle cannot be polished at all, so that the problem of how to reduce the internal friction coefficient is solved.
