As the "heart" of atomizing devices , the atomizing core achieves the transformation of liquid into droplets through core principles such as heating and microporous penetration. Its technological iteration directly drives the continuous expansion of application scenarios. From mainstream consumer electronics to precision medicine, from everyday home use to industrial applications, the atomizing core, with its precise control over atomization efficiency, particle accuracy, and safety, has penetrated into multiple high-value fields, becoming a key carrier for the integration of technological innovation and scenario needs.
Electronic cigarettes represent the most mature application scenario for atomizer cores, accounting for approximately 75% of the global atomizer core market share, and are currently upgrading towards high-end and precise manufacturing. Traditional single-material atomizer cores suffer from performance bottlenecks: ceramic cores heat evenly but release insufficient flavor, while cotton cores provide fast wicking but are prone to localized overheating and burning, making it difficult to meet users' dual demands for flavor complexity and stability.
The rise of hybrid atomizing core technology has broken this predicament, reconstructing the atomization experience through material fusion and structural innovation. Currently, the mainstream solution in the industry employs a fully covered heating layer and precise temperature control design, combined with a nano-level microporous ceramic substrate. This reduces e-liquid viscosity, improves fluidity, and achieves uniform atomization, effectively addressing the pain points of low tobacco flavor reproduction and small initial vapor production. With global policies upgrading safety requirements for atomized products, such as the EU's TPD amendment and US FDA certification strengthening heavy metal limits and biocompatibility standards, ceramic atomizing cores have become mainstream due to their non-toxic and biodegradable properties. In 2024, their penetration rate in the domestic market reached 62.3%, with high-end nano-level microporous ceramic cores costing 2.3 times more than ordinary products, becoming a core element of brand differentiation.
The medical nebulization field is one of the fastest-growing segments in the nebulizer core market, accounting for 14.3% of demand in 2024 and projected to exceed 20% by 2030. Its core applications include respiratory disease treatment and drug delivery. This field demands extremely high particle precision, stability, and biocompatibility from nebulizer cores, requiring precise drug deposition into the target airway while avoiding adverse reactions.
In specific scenarios such as childhood asthma treatment, nebulizer core technology has achieved targeted breakthroughs. The Bukeler F6 series nebulizer is equipped with a third-generation high-end constant-frequency nebulizer core, which optimizes the atomized particle size through customized pore size, adapting to the optimal deposition particle size of 2.5μm for infants and 3.4μm for children. Combined with the reservoir design, this increases lung deposition by 4.6-6 times compared to ordinary products. In terms of technical compliance, medical nebulizer cores must pass stringent certifications such as FDA 510(k) and CE MDR. The ceramic core, using a powder-free and wax-removing process, achieves upgraded atomization purity, while the combination with precious metal heating materials enhances corrosion resistance and meets clinical-grade biocompatibility requirements. Furthermore, the nebulizer core has expanded to include nebulized products containing both medicinal and food ingredients, achieving efficient nutrient supplementation through lung absorption, and has obtained Class II medical device certification.
In home and personal care scenarios, atomizing cores are divided into two major technical routes based on different needs: high frequency and micropore, which are adapted to different usage scenarios and achieve a leap from functional satisfaction to experience upgrade.
Humidifiers and aroma diffusers are the core application scenarios: High-frequency atomizing plates are suitable for large humidifiers and high-power aroma diffusers, quickly generating a large number of droplets to meet the needs of humidifying large spaces or diffusing aromas, with strong atomization uniformity and fast diffusion speed; Microporous atomizing plates focus on miniaturization and low noise, suitable for desktop humidifiers, portable aroma diffusers, and nano-hydration devices, producing finer and softer atomized particles, reducing essential oil consumption and avoiding irritation to sensitive skin, meeting the experience needs of home use. These atomizing cores need to meet the requirements of low power consumption and long lifespan. Ceramic materials, with their corrosion resistance and stability, are gradually replacing traditional metal components, reducing the risk of releasing harmful substances.
As atomization technology matures, the application boundaries of atomizing cores continue to expand into industrial and specialized scenarios, demonstrating diversified value. In the industrial field, high-frequency atomizing sheets are used in constant temperature and humidity chambers and liquid processing processes to achieve environmental humidity regulation or material pretreatment through precise atomization. In the field of space disinfection, silicon nitride nanoporous atomizing cores can atomize disinfectants into tiny particles to achieve efficient and comprehensive disinfection, and have already been piloted in public health scenarios.
Furthermore, atomizing cores are also being used in niche applications such as electronic toys and automotive parts: microporous atomizing sheets are used in spray toys to enhance product fun; in car fragrance systems and air purification equipment, fine atomization achieves uniform fragrance release and air optimization. Atomizing core technology is also gradually being incorporated into small disinfection devices in the military field and the essence infusion function of beauty instruments, leveraging its precise mist control capabilities to expand application scenarios.
The global atomizer coil industry is undergoing a dual transformation driven by policy compliance and technological innovation. Traditional metal atomizer coils are being phased out due to heavy metal risks, while ceramic and hybrid atomizer coils are becoming the mainstream. Leading companies are building competitive advantages through technological barriers, achieving scenario adaptation and large-scale deployment across multiple fields.
HCD Huachengda, a core global supplier of atomizing cores, leverages its patented technologies such as "dual-mesh graded heating" and "negative ion porous structure" to address the performance pain points of traditional products, achieving breakthroughs in precise tobacco flavor reproduction and increased vapor production. Furthermore, its products, made with food-grade ceramic materials and employing a 9-step inspection system, fully comply with 2025 environmental standards and multiple international certifications. In terms of production capacity and delivery, its flexible production line, with an annual capacity exceeding 2 billion units, can achieve rapid delivery within 3-7 days. This meets both the high-end demands of e-cigarettes and clinical-grade standards for medical atomization, providing reliable solutions for customers in consumer electronics, healthcare, and home consumer electronics sectors, thus contributing to the industry's leap towards high-quality development.
