Problems solved by technology

When the water level in the water tank is low, the water pressure on the atomizing sheet is correspondingly small. Although the output power of the atomizing sheet is still as large as before, since the water that needs to be pushed is reduced a lot, the spray volume will naturally increase significantly. This results in less fog when there is a lot of water, and a lot of fog when there is less water, and the spray speed is obviously accelerated, which cannot meet the requirements of uniform spray

Abstract

The invention discloses an ultrasonic aromatherapy device with the constant spraying amount and relates to the technical field of ultrasonic aromatherapy. The device comprises a water tank, a main control module, an ultrasonic frequency sweeping module and a water level detection module, the main control module is connected with the ultrasonic frequency sweeping module and the water level detection module separately, and the water level detection module is used for detecting the height of the water level in the water tank. According to the ultrasonic aromatherapy device with the constant spraying amount, the height of the water level in the water tank is detected through the water level detection module, the spraying output power is automatically adjusted, the spraying amount is adjusted,and the stable spraying speed is achieved.

Description

technical field [0001] The invention relates to the technical field of ultrasonic aromatherapy, in particular to an ultrasonic aromatherapy device with constant spray volume. Background technique [0002] Due to the individual differences in the resonant frequency of ultrasonic atomizing sheets, the existing separately excited ultrasonic aromatherapy machine driven by CPU frequency tracking uses the CPU to output a frequency sweep change signal in a certain frequency range to drive the MOS tube and boost inductor to generate high voltage. The alternating waveform is used to drive the ultrasonic atomizing sheet to work, and at the same time, the working current of the circuit is converted into a feedback voltage through the sampling resistor for CPU frequency detection. When the CPU detects that the feedback voltage corresponding to a certain frequency sweep signal is the maximum value, it is regarded as the best resonance point of the ultrasonic atomizing sheet and written i...
