AI Technical Summary

Technical Problem

Existing quantitative droplet dispensing devices lack precision in controlling large liquid volumes and cannot adjust droplet size according to different needs, resulting in low efficiency.

Method used

The system employs a liquid spraying device. The control unit receives target liquid spraying information, the droplet driving unit generates a liquid spraying waveform signal, and the liquid supply device supplies liquid in a stabilizing and constant flow manner. The spray head responds to the waveform signal to perform quantitative and variable control. Combined with a flexible lever structure and a solenoid valve, the system achieves high-precision droplet spraying.

Benefits of technology

It achieves high-precision control of droplet size, and the spraying device maintains stability and consistency at high frequencies, greatly simplifies the number of components, and improves the stability of the spraying system and the consistency of droplets.

Abstract

This disclosure relates to a liquid spraying device, characterized in that it includes: a control unit, a spray head, a droplet driving unit, and a liquid supply device. The control unit is configured to receive target liquid spraying information, the target liquid spraying information including the droplet volume and number of sprays per spray as set according to requirements. The droplet driving unit is configured to generate a corresponding spraying waveform signal based on the droplet volume and the number of sprays. The liquid supply device is configured to supply target liquid to the spray head in a voltage-stabilized and constant-flow manner, and the spray head, in response to the spraying waveform signal, sprays the target liquid supplied by the liquid supply device from one or more outlets with the set droplet volume and number of sprays per spray.
