Piezo Direct stands at the forefront of innovation, specializing in the development and production of cutting-edge piezo atomizers. Our commitment lies in harnessing the remarkable properties of piezoelectric technology to create ultrasonic marvels capable of vibrating and atomizing liquids.
Piezo Direct can provide three types of atomizers, namely single-chip piezo mesh atomizer, ultrasonic atomizer, and focused ultrasonic atomizer. Each type has its own characteristics and advantages, which will be introduced separately below.
Single-Chip Piezo Mesh Atomizer
At the core of our technology lies the single-chip piezo mesh atomizer, a testament to engineering and efficiency. Designed with a focus on versatility, these atomizers cater to a broad spectrum of applications, making them the ideal choice for industries ranging from healthcare to agriculture.
Key Features of our Single-Chip Piezo Mesh Atomizer
- Metal Mesh Mastery: Our piezo atomizers leverage the power of meticulously crafted metal mesh technology. The intricate design utilizes the sides of the mesh to achieve exceptional liquid atomization, ensuring optimal performance.
- Fine-tuned Efficiency: Optimal Driving Voltage (50 to 80Vp-p): Engineered for peak efficiency, our piezo atomizers operate within an optimal driving voltage range of 50 to 80Vp-p. This meticulous calibration guarantees flawless operation, maximizing the potential of your application.
- Frequency Finesse: Adaptable Signal Frequency: Our piezo atomizers demonstrate remarkable adaptability, seamlessly working with a sine signal frequency tailored to the specific requirements of each application. This ensures perfect harmony between the driving force and the atomizer, leading to superior results.
- Environmental Adaptability: Built to Withstand: These robust piezo atomizers are designed to function flawlessly within a temperature range of -10 to 40°C and an environment with humidity levels of up to 75%. This adaptability allows for their integration into diverse environments without compromising performance.
Ultrasonic Atomizer
The ultrasonic atomizer is a highly efficient atomizer that combines piezoelectric technology and material innovation. Its core advantages stem from its unique structural design and material properties. This atomizer uses piezoelectric ceramic as the substrate, and its surface is covered with a glass glaze coating fired at high temperature. This composite structure not only retains the high-frequency vibration characteristics of the piezoelectric material but also achieves excellent acid, alkali and moisture resistance through the glass glaze layer. It can adapt to various liquid environments such as water, essential oils, and medicinal liquids, effectively solving the problem of easy corrosion of traditional nickel-plated or titanium-plated atomizers.
Key Features of our Ultrasonic Atomizer
- Atomization efficiency: Our ultrasonic atomizer features outstanding atomization efficiency and a large flow rate. Combined with high-frequency vibration, it can convert liquid into delicate micron-sized particles, enhancing the atomization absorption effect.
- high energy conversion efficiency: Our ultrasonic atomizer has high energy conversion efficiency. The impedance of the product is as low as below 2Ω, with small dielectric loss. It generates little heat during operation, combining energy – saving and stability.
- An extremely long service life: The service life of our ultrasonic atomizers far exceeds that of traditional products. The cumulative working time can reach over 8000 hours, and it has excellent long – term stability.
- The surface is smooth and flat: After high – temperature treatment, the glaze surface has high microscopic flatness. It combines self – cleaning function and antibacterial properties, reducing the adhesion of scale and the growth of bacteria, and lowering the maintenance frequency.
Focused Ultrasonic Atomizer
The focused ultrasonic atomizer achieves a dual breakthrough in energy utilization and atomization efficiency through an innovative structural design. Compared with traditional flat atomizer, its core advantage lies in the precise concentration of vibration energy through the optimization of physical structure, forming a highly efficient atomization field. It specifically adopts a spherical piezoelectric ceramic substrate; the spherical curvature design focuses the ultrasonic vibration energy on the atomization area. It can be driven with only relatively low voltage and power, reducing energy consumption by more than 60% compared with traditional products, and increasing the atomization volume by 30% under the same conditions. From the physical innovation of energy focusing to the precise adaptation to multiple scenarios, this type of atomizer redefines the efficiency standard of atomization technology.
Key Features of our Focused Ultrasonic Atomizer
- Efficient Energy Concentration with Significantly Reduced Loss: A spherical piezoelectric ceramic substrate is adopted, and the ultrasonic vibration energy is accurately focused on the atomization area through the optimization of physical structure, avoiding the energy dispersion problem of traditional flat atomizers. It can be driven with a minimum voltage of only 5V and a current of 1A. Compared with traditional products, its energy consumption is reduced by more than 60%, and the atomization efficiency is increased by 40% under the same power, realizing “low consumption and high energy” operation.
- Controllable Atomization Precision and Excellent Particle Uniformity: The median particle size can be accurately adjusted according to scenarios. The particle uniformity is improved by more than 30% compared with traditional flat atomizers, which effectively solves the unstable atomization effect caused by edge water accumulation and uneven particle size.
- Low Consumption, Long Battery Life and More Outstanding Portability: Relying on the low-power design of core components, the battery life of the portable focused atomizer is greatly improved. It is especially suitable for mobile scenarios such as home medical care and outdoor aromatherapy, balancing performance and ease of use.
- Support for Customized Design in Multiple Fields: According to different applications, focusing points and power requirements, customized design and production are provided.
Specialization in Small Particle Generation
Piezo Direct specializes in producing atomizers that generate exceptionally small particles, making them ideal for applications like nebulizers. This is because only particles smaller than 5 micrometers can effectively reach the lungs. To maximize nebulizer effectiveness, it’s crucial to produce as many particles as possible within this size range.
Our technology allows for the creation of mesh holes as small as 2.5 microns, the smallest achievable size with current mesh-based atomizer technologies. Since particle size (or Mass Median Aerodynamic Diameter, MMAD) directly correlates with mesh hole size, our atomizers are particularly well-suited for nebulizer applications.
Beyond Nebulization
Piezo atomizers have applications in a multitude of industries, including:
- Medical and Healthcare: Targeted respiratory treatments become a reality with the integration of our atomizers into inhalation therapy devices.
- Agricultural Revolution: Cultivate efficiency in crop spraying systems. Our atomizers ensure the meticulous distribution of pesticides, fertilizers, and growth regulators, empowering agricultural advancements.
