Mini-mist spray system resonance frequency adjusting method and device thereof

Abstract

The invention disclosed a resonant frequency modulation method and means for micro-spray system, solve the resonant frequency drift problems when atomizing, the invention of the means including: fluidstorage unit; Micro-spray unit to atomization liquid in the fluid storage unit by the wan of shock, and resonance frequency adjustment unit, with a Resonance frequency adjustment components, adjust its resonance frequency through throw different pressures to the micro-spray unit. This invention is resolved solve the problem of the resonant frequency drift, and the micro-spray system to avoid theinfluence of environmental factors lead to its resonant frequency drift, thereby increasing system stability, so as to maintain maximum fixed spray flow and spray area, it could provide a stable micro-spray system and better work efficiency, and through simple adjustments and control framework, simplify the difficulty of controlling the resonant frequency, had overcome the problems of prior art relatively.

Description

technical field [0001] The invention relates to a spray system resonance frequency modulation technology, in particular to a micro spray system resonance frequency modulation method and a device thereof. Background technique [0002] The application of the spray system has been practiced for many years. Most of the early spray systems used gas pressurization to atomize the liquid as the main technology and application. Due to higher efficiency and lower space occupancy, the micro-spray system made of piezoelectric material for atomization has also emerged. At present, the piezoelectric micro-spray system has the characteristics of miniaturization and energy saving. , The field of application is very wide. This piezoelectric micro-spray technology has been applied in the micro-cooling (Micro-cooling), which is used in the field of computer heat dissipation and cooling. Because of the continuous improvement of computer speed and function, the relative working speed of the cen...

Problems solved by technology

[0006] However, the current solution is to change the output parameters by circuit control, or use circuit control and feedback to detect the resonant frequency and use the control circuit output to lock the resonant frequency range, so as to realize the control system running at the resonant frequency, or The operation mode of detecting the voltage phase difference and cooperating with the resonant frequency calculation circuit and the initial resonant frequency value to know the resonant frequency that should be output after the environment changes are all through complex circuit design to improve the problem of resonant frequency drift, not just through simple Calibration technology to achieve resonance frequency modulation

[0007] Most of the above patents use the control circuit to enable the system to operate at the resonance frequency, but the resonance frequency is not the same before and after operation, so it may have different flow performance or other changes and influences when applied to the micro-spray system, so it also improves system work uncertainty
