Application of heating sensors in piezoelectric atomizers to improve atomization effect

As an efficient and convenient atomization device, piezoelectric atomizers are widely used in medical, humidification, aromatherapy and other fields. Its core principle is to use the inverse piezoelectric effect of piezoelectric ceramics to convert electrical energy into mechanical energy, so that the liquid produces high-frequency vibrations, thereby atomizing the liquid into tiny particles. However, traditional piezoelectric atomizers usually do not have a heating function, which limits their application in certain fields, such as medical atomization that requires heating of liquid medicine to enhance the efficacy, or aromatherapy liquid that requires heating to enhance the aromatherapy effect. The introduction of heating sensors has brought the ability of precise temperature control to piezoelectric atomizers, enabling them to meet the needs of more application scenarios, especially in improving the atomization effect.

Principle of heating sensors to improve atomization effect

The core principle of heating sensors to improve the atomization effect in piezoelectric atomizers is to accurately control the temperature of the liquid. Some liquids can only work best at a specific temperature, for example:

Drug solution: Some drugs are more soluble at a specific temperature and are more easily absorbed by the human body after atomization, thereby enhancing the therapeutic effect.
Aromatherapy essential oils: Some aromatherapy essential oils are more volatile at a certain temperature, which can release aroma faster and improve the aromatherapy effect.
Food additives: Some food additives can be better mixed with food after being atomized at a certain temperature, improving the taste and flavor of the food.
The heating sensor ensures that the liquid is atomized at the optimal temperature by real-time monitoring and precise control of the temperature of the liquid, thereby improving the atomization effect.

Working mechanism of heating sensor
The heating sensor is usually composed of a temperature sensor and a heating element in a piezoelectric atomizer. Its working mechanism is as follows:
1. Temperature monitoring: The temperature sensor monitors the temperature of the atomized liquid in real time and transmits the temperature signal to the control system.
2. Signal feedback: The control system calculates the heating power that needs to be adjusted based on the difference between the set temperature and the actual temperature.
3. Power regulation: The control system controls the liquid temperature by adjusting the power of the heating element, such as a resistance wire, a PTC heating sheet or a thick film heater.
4. Closed-loop control: The entire system forms a closed-loop control loop to ensure that the liquid temperature is always maintained within the set range.
Advantages of heating sensors to improve atomization effect

The precise temperature control capability brought by heating sensors brings the following advantages to piezoelectric atomizers to improve atomization effect:

Finer atomized particles: Heating can reduce the viscosity and surface tension of the liquid, making it easier to atomize, thereby producing finer and more uniform atomized particles.

Higher atomization efficiency: Heating can accelerate the atomization process of the liquid and improve the atomization efficiency, thereby producing more atomized particles in a shorter time.
More stable atomization effect: The heating sensor can ensure that the liquid temperature is always maintained within the optimal range, thereby ensuring the stability of the atomization effect.
