Product details

When commissioning the development of atomizer plates for beauty sprayers, international clients prioritize seamless compatibility with key components such as the piezoelectric ceramic transducer, dental scaler, and scaler tools, avoiding substandard end-device performance due to technical parameter mismatches. This focus focuses on three aspects: technical parameter coordination, component compatibility design, and cross-scenario technology migration.

The Liandaqi Atomizer Plate, a core atomizing engine designed specifically for facial hydration devices and nano-mist sprayers, produces an ultra-fine, highly uniform cooling mist with a 5μm fine mist that deeply penetrates the skin, reaching the base layer for highly effective hydration and essence delivery. From medical-grade precision to cosmetic-grade fineness, we deeply understand the boundaries of piezoelectric ceramics. The Liandaqi Atomizer Plate is not just a component, but the scientific foundation for your product's "absorption" and "efficacy promise."

What technological breakthroughs did we achieve in designing this Atomizer Plate?

1. True nano-level fine atomization: Through this product design, we achieved precise control over the particle size, stabilizing the atomized particle size DV50 at 3-8μm (customizable to below 3μm), producing an invisible "dry mist" that gently covers the face without any water droplets. The product boasts high uniformity; a unique vibration mode design ensures a uniform and stable mist field, delivering equal amounts of nutrients to every inch of skin.

2. Excellent compatibility and activity protection: Achieving wide liquid compatibility and room-temperature atomization, it is specifically optimized for water-based formulas, perfectly compatible with toners, serums, hydrosols, diluted serums, and lightweight lotions, effectively atomizing without clogging. Utilizing piezoelectric cold atomization technology, it generates no heat throughout the process (<1°C temperature rise), fully protecting heat-sensitive active ingredients in skincare products (such as Vitamin C, peptides, and enzymes).

3. Ultra-quiet and pleasant experience: It provides a library-level level of quietness and vibration-free operation. We've reduced operating noise to < 25 dB(A), creating a soothing and immersive skincare experience, like a gentle breeze. Optimized structural balance ensures minimal handheld vibration, enhancing user comfort and a premium feel.

4. Miniaturization and Energy-Saving Design. Extremely compact and energy-efficient. The module height can be integrated to less than 8mm, with a minimum diameter of Φ10mm, enabling portable, lipstick-style hydration devices. Operating voltage can be as low as 3.0V, with a single use (10 minutes) consuming approximately 100mAh, significantly extending the battery life of wireless devices.

The piezoelectric ceramic transducer is the core component of the atomizer plate for high-precision atomization. Matching its technical parameters is a top priority in the development of atomizer plates for beauty sprayers. For beauty spray applications (such as nano-scale facial hydrating sprayers), foreign customers require that the atomizer plates developed be compatible with piezoelectric ceramic transducers of different specifications (such as diameters of 10-20mm and thicknesses of 0.5-1.2mm), with an oscillation frequency synchronization accuracy of ≤±1kHz.

For example, when adapting to a 16mm diameter piezoelectric ceramic transducer, the atomizer plate needs to stabilize the driving frequency at 110-130kHz to ensure that the transducer efficiently converts electrical energy into mechanical oscillations, achieving nano-scale atomized particles (diameter ≤5μm) and an atomization volume error of ≤±5% (for example, when the atomization volume is set at 0.8ml/h, the actual output range is 0.76-0.84ml/h), meeting the core requirement of "delicate and non-irritating" facial hydration (user skin irritation feedback rate ≤0.3%). In toothbrush handpiece applications (such as the atomization cleaning function of ultrasonic toothbrush), customers require dual-frequency coordination between the atomizer plate and the piezoelectric ceramic transducer within the toothbrush handpiece.

The ultrasonic oscillation frequency of the toothbrush handpiece (28-32kHz) is used for calculus removal, while the transducer frequency driven by the atomizer plate (100-120kHz) is used to atomize the cleaning solution. The frequency interference rate between the two frequencies should be ≤5% to avoid mutual interference that could lead to reduced toothbrush effectiveness or interrupted atomization. Furthermore, the atomizer plate should automatically adjust the atomization volume based on the toothbrush handpiece's operating status (e.g., starting, pausing, or switching gears). For example, the atomization volume should increase to 1.2ml/h when toothbrush is started and decrease to 0.2ml/h when paused), achieving synchronized "cleaning and atomization" coordination. In addition, the customer was interested in the atomizer's "protection design" for the piezoelectric ceramic transducer.

This included developing an overvoltage protection circuit (automatically limiting the current when the transducer voltage exceeds 5V DC) and a temperature compensation function (within the ambient temperature range of 5-40°C, the transducer oscillation frequency fluctuation is ≤±2kHz). This prevented transducer damage due to abnormal parameters (damage rate ≤0.1%) and extended the service life of core components (≥5000 hours of continuous operation).

Client Success Stories

Case 1: A New Beauty Device Brand – The client needed an "oxygenation" essence infusion device project and wanted to develop a high-end infusion device based on the concept of "high-pressure oxygenation and nano-penetration enhancement."

The core challenges were:

1) Most atomizing pads on the market have a particle size greater than 15μm, making it impossible to achieve the advertised "nano-penetration enhancement" effect;

2) The device needed to simultaneously atomize two formulas: high-purity oxygenated water and high-concentration peptide essence, requiring stringent compatibility and stability requirements;

3) The product was positioned as a luxury item, demanding extremely quiet operation.

Liandaqi's Solution:

1. Joint Development of a Customized Atomizing Core: Based on the HYD-5V-Plus platform, adjustments were made to the microporous structure and vibration parameters, successfully stabilizing the average atomized particle size at 5.2μm, and providing a third-party testing report.

2. Dual-Liquid Path System Support: Targeted atomizing pads were configured for each of the two independent liquid paths, and suggestions were provided for anti-crystallization and clogging coating treatments for the essence path.

3. Acoustic and Experience Optimization: The drive waveform and atomizing chamber structure were redesigned, reducing operating noise from a typical 35dB to the customer-required 24dB, and eliminating high-frequency noise.

Result: With its genuine "5μm nano-mist" detection data and near-silent luxury experience, the product achieved great success on crowdfunding platforms, selling out quickly despite a price exceeding $300. The stability and fineness of its atomizing core received unanimous praise from professional beauty bloggers, becoming a technological benchmark for the brand.
