Ceramic Core | Ceramic Atomizing Core for Waterless Aroma Diffusers & Fragrance Machines

Ceramic Core is a high-performance ceramic atomizing core for fragrance machines, waterless aroma Diffusers, cold mist diffusers, home waterless aroma diffusers, and car aroma diffusers. OEM/ODM waterless aroma diffuser customization available.

Description

Qiwuecy Ceramic Core is a core atomizing component developed by Qiwuecy based on years of atomization technology research and accumulated experience. Designed for health-oriented atomization scenarios, it serves as the “power core” of fragrance machines, waterless aroma diffusers, cold mist diffusers, and other aroma devices. The ceramic core directly determines atomization efficiency, fragrance restoration, and safety performance. Qiwuecy Ceramic Core is built on porous ceramic material technology and integrates precision thick-film printing processes with gradient pore structure design. It comprehensively solves the core pain points of traditional cotton wicks, including dry burn, burnt core, leakage, fragrance decay, and poor consistency.

Atomizing core technology has evolved from glass fiber wicks to traditional cotton wicks, and then to ceramic cores. With precise temperature control capability, ceramic cores fundamentally solve problems such as dry burn, unstable fragrance, and burnt cores commonly found in traditional atomizing cores. They also solve the challenges of industrial mass production and assembly. While inheriting the core advantages of ceramic atomization technology, Qiwuecy Ceramic Core further optimizes pore structure regulation and integrated heating component design, providing highly reliable atomization core solutions for home waterless aroma diffusers, car aroma diffusers, cold mist diffusers, and other health-oriented fragrance devices.

Technical Specifications

Core Structure of the Ceramic Atomizing Core

The structural design of Qiwuecy Ceramic Core focuses on three core objectives: efficient liquid guiding, uniform heating, and stable atomization. It mainly consists of a porous ceramic matrix, a heating component, and an auxiliary fixing structure. These components work together to achieve efficient conversion from fragrance oil to aerosol.

1. Porous Ceramic Matrix

The porous ceramic matrix is the load-bearing core of the atomizing core. Qiwuecy selects high-purity alumina, zirconia, diatomaceous earth, and other ceramic materials. The pore structure is precisely regulated through pore-forming agents and formed through high-temperature sintering at 600–1200°C. Its typical parameters include a porosity of 30%–70% and an average pore size of 1–70μm, forming an interconnected honeycomb-like micro-pore network internally. Structurally, it adopts hollow cylindrical, boat-shaped, or semi-cylindrical designs. The surface contacting the fragrance oil is the liquid inlet surface, while the surface embedded with the heating element is the atomization surface. Through reasonable design of different pore size gradients, liquid absorption and atomization performance complement each other, greatly improving the overall performance of fragrance machines, waterless aroma diffusers, and cold mist diffusers.

2. Heating Component

The heating component is key to energy conversion. Qiwuecy Ceramic Core adopts a resistive heating film solution. Alloy resistance paste is printed onto the ceramic matrix surface through a screen printing process and sintered at 1000°C under nitrogen protection. The circuit shape uses optimized designs such as S-shaped and wave-shaped patterns to increase the heating area, with resistance controlled within the range of 0.7–3.0Ω. The excellent thermal conductivity of ceramic materials allows heat to be quickly and evenly transferred to the atomization surface. Temperature control accuracy is significantly better than traditional cotton wicks, effectively avoiding carbon deposition and burnt core issues caused by local overheating.

3. Auxiliary Fixing Structure

The auxiliary fixing structure includes a disc-shaped fixing part for connecting to the device bracket. Reinforcing ribs are added between the fixing part and the ceramic column to improve structural stability. At the same time, a heat insulation component is provided to reduce heat conduction to the bracket. The airflow channel design ensures smooth export of the aerosol after atomization, forming a reasonable gas-liquid circulation path.

Core Working Principle of the Ceramic Atomizing Core

The working process of Qiwuecy Ceramic Core is essentially an energy conversion chain of electrical energy—thermal energy—aerosol. It is divided into three key stages: liquid guiding, heating, and atomization. Relying on ceramic material properties and structural design, it achieves efficient coordination.

1. Capillary Liquid Guiding Stage

The fragrance oil in the liquid storage chamber generates capillary action through the micro-pore structure of the ceramic matrix and penetrates into the entire ceramic core along the liquid inlet surface. The high porosity and interconnectivity of porous ceramics ensure rapid diffusion of fragrance oil. At the same time, micro-pores can absorb an appropriate amount of fragrance oil to form a liquid film, achieving a dynamic balance between “liquid supply and atomization” and avoiding dry burn or liquid accumulation. Due to surface tension and capillary action, the fragrance oil can be evenly absorbed into the atomizing core and attached to its surface.

2. Energy Conversion Stage

After power is supplied, the resistive heating film converts electrical energy into thermal energy through Joule heating. The excellent thermal conductivity of ceramic materials allows heat to be quickly and evenly transferred to the atomization surface. Temperature control accuracy is significantly better than traditional cotton wicks, effectively avoiding local overheating, reducing carbon deposition and burnt core issues. Compared with metal wire resistance atomization technology, ceramic thick-film atomization technology uses the numerous micro-pores of the ceramic body to evenly guide fragrance oil into the heating area through surface tension and capillary action. It offers advantages such as high temperature resistance, large heating area, uniform temperature field distribution, and easy assembly.

3. Atomization Molding Stage

When the atomization surface temperature reaches the boiling point of the fragrance oil, the surface liquid film rapidly evaporates into fine droplets, which then mix with airflow to form an aerosol. The combination of a mesh heating film and gradient pore structure makes atomized particles finer and more uniform, improving fragrance restoration. At the same time, by regulating heating power, the atomization volume and particle size can be precisely controlled to adapt to different usage scenarios such as home waterless aroma diffusers and car aroma diffusers.

Core Advantages

• Precise Temperature Control: The thermal conductivity of ceramic materials makes heat distribution more uniform. Temperature control accuracy is significantly better than traditional cotton wicks, effectively avoiding burnt core and carbon deposition caused by local overheating.
• Dry Burn Resistance and High Temperature Resistance: The ceramic matrix offers excellent high-temperature resistance. Even short-term dry burning does not produce a burnt odor, greatly improving safety.
• Fine Atomization and Stable Fragrance: The micro-pore atomization technology of the ceramic core can achieve micron-level atomized particles, making the fragrance aerosol finer and delivering a purer, more stable fragrance experience.
• Long Service Life Design: Ceramic materials have strong chemical stability, corrosion resistance, and aging resistance. Service life is significantly better than traditional cotton wicks, reducing replacement frequency.
• Industrial Mass Production Consistency: Precision sintering processes and thick-film printing technology enable precise regulation of ceramic matrix porosity and pore size, ensuring high batch-to-batch performance consistency and meeting the needs of industrial large-scale production.
