. Piezo nebulizer, also known as ultrasonic nebulizer, is a device that breaks liquids into fine droplets. This is done by using piezoelectric crystals that vibrate when an electrical voltage is applied. These vibrations produce ultrasonic waves that break up the liquid into droplets just a few micrometers in size.

The construction of a piezo nebulizer is simple. It consists of a reservoir containing the liquid, a piezoelectric plate and an air stream. The piezoelectric plate is supplied with an electrical voltage. When voltage is applied, the plate vibrates. These vibrations create ultrasonic waves that propagate through the liquid. The ultrasonic waves create cavitation. Cavitation is the appearance of bubbles in a liquid. These bubbles form when the pressure fluctuations of the ultrasonic waves overcome the liquid surface tension. The bubbles are very small and burst quickly. When the bubbles burst, excess pressure is created, which breaks the liquid into droplets. The droplet size depends on the frequency of the ultrasound waves. The higher the frequency, the smaller the droplets are.

Piezo nebulizers have a number of advantages over other types of nebulizers, including: they are small and portable, are relatively inexpensive & produce fine droplets.

. Overall, piezo nebulizers are a versatile and effective way to break liquids into fine droplets. They are used in a variety of applications including medical inhalation therapy, air humidification and food processing:

Humidification: Piezo nebulizers are often used in humidifiers to atomize water into tiny droplets and increase indoor humidity.

Aromatherapy: They are used in aromatherapy diffusers to diffuse essential oils into the air, creating a pleasant scent and potentially providing health benefits.

Medical applications: In medical technology, piezo nebulizers are used in inhalation devices to atomize medication into the finest particles, which can then be more easily inhaled by patients, for example in the case of asthma or other respiratory diseases.

Ultrasonic Cleaners: Piezo nebulizers also play a role in ultrasonic cleaners, which can remove dirt and contaminants from various materials by sending high-frequency sound waves through a liquid in which the object to be cleaned is placed.

Laboratory Applications: In laboratories, piezo nebulizers can be used to generate fine droplets for various experiments and analysis, such as for aerosol research or to generate test nebulae.

. Piezo nebulizer with control electronics

. Ultrasonic nebulizers with control electronics work with the optimal resonance frequency. They are supplied with a low alternating voltage.

. It is absolutely important that a minimum column of the medium to be atomized lies above the piezo disk in a controlled manner. Both liquids and powdery substances can be nebulized.

. These units are used for humidifying rooms, such as storage rooms for food, vegetables, tea, flowers, bread dough, etc., for humidifying shop counters, e.g. B. in butcher departments. The currently most important area of ​​application is medical technology, for example with inhalation devices and biochemistry.

. A piezo nebulizer without control electronics is an ultrasonic nebulizer that only consists of a piezo oscillator. The piezo oscillator is a ceramic disc that vibrates under the influence of electricity. These vibrations are transmitted to a fluid located on the surface of the disk. This atomizes the liquid into small droplets. Piezo nebulizers without control electronics are generally used in applications in which the amount of liquid or droplet size does not need to be precisely adjusted. Examples include humidifiers, aromatherapy devices and medical applications such as inhalers. The advantage of piezo nebulizers without control electronics is that they are very cost-effective. The disadvantage is that they are not as versatile as piezo nebulizers with control electronics.

The most important features of piezo nebulizers without control electronics: they consist only of a piezo oscillator, are driven by the current flow through the piezo oscillator and are very cost-effective.
