Novel vehicle-mounted aromatherapy machine for vibration detection

Abstract

The invention discloses a novel vehicle-mounted aromatherapy machine for vibration detection, including an ultrasonic atomization control circuit, a vibration detection circuit and an MCU, the ultrasonic atomization control circuit comprises an ultrasonic oscillation circuit and an oscillation driving circuit, The vibration detection circuit detects the vibration condition of the automobile and outputs a vibration detection signal to the MCU, the MCU outputs a PMW control signal to the oscillation driving circuit according to the vibration detection signal, and the oscillation driving circuitoutputs a driving signal to drive the ultrasonic oscillation circuit to start the oscillation operation. The new type of vehicle-mounted aromatherapy machine for vibration detection, the MCU outputs aPMW control signal to the oscillation driving circuit according to the vibration detection signal, The PMW control signal is inputted to the oscillation driving circuit to change the output magnitudeof the driving signal, and the oscillation amplitude and frequency of the ultrasonic oscillation circuit change with the change of the PMW control signal, thereby realizing the automatic adjustment of the atomization ability.

Description

technical field [0001] The invention relates to ultrasonic atomization equipment, in particular to a novel vehicle-mounted aroma diffuser with vibration detection. Background technique [0002] Now many families have their own cars, and everyone is more concerned about the maintenance of their cars. Many car owners will put a car aromatherapy machine in the car, which can not only improve the smell in the car, but also relieve the fatigue of driving. The aromatherapy atomization of most of the car aromatherapy machines on the market in the past utilizes two natural laws, one is the law of Bernuck's fluid mechanics, and the other is the Lenard ion effect. The whole fragrance expansion process is carried out at room temperature. That is to say, based on the principle of oscillating gas atomization, the essential oil is diffused through air pressure, and hundreds of millions of particle molecules can be released without heating, and quickly disintegrate in the air to form an a...

AI Technical Summary

Problems solved by technology

[0003] 1. The car aromatherapy machine mainly uses mechanical principles for atomization. The system still works when the essential oil is used up, and there is no water shortage protection function;

[0004] 2. The system has poor scalability and no other personalized visual improvement functions, which cannot meet people's growing needs for personalization and intelligence;

[0005] 3. The atomization capacity of the system is single, and there is no automatic adjustment function, resulting in waste of cost;

[0006] 4. The stability of the system is poor. Due to the volatilization caused by mechanical characteristics, when the car is driving on a potholed mountain road, it is easy to cause essential oil to overflow and leak
