Fragrance machine is very common electrical appliances in life, it is through ultrasonic shock equipment of high frequency shock, the water molecules and plant oil decomposition into fog into the air, as the incense machine continuous work, incense machine essential oil will gradually reduce, so how in the case of essential oil quickly no remind users to add liquid in time?
Can be realized by the level sensor liquid remind function, in the machine installed a capacitive liquid level sensor, capacitor liquid level sensor is not contact, do not need to contact the liquid can detect, the sensor is installed at the bottom of the insulated tank (detect water shortage) or the side of the tank (detect low liquid level), when the liquid level is lower than the detection point of the sensor, sensor induction liquid, will send a signal to remind the user to add liquid.
Capacitive liquid level sensor has a small volume, high detection accuracy and convenient installation. The fuselage space of the incense smoke machine is limited, so the use of a capacitive liquid level sensor is more appropriate.
