Description

Technical Field

[0001] The present invention relates to the technical field of ceramic processing, in particular to a black pottery aromatherapy vessel and a preparation method thereof. Background Art

[0002] Aromatherapy refers to products formulated using essential oils or fragrances extracted from aromatic plants as a medium. They primarily act through the respiratory and dermal systems to achieve relaxation, improved sleep, and enhanced immunity. Aromatherapy encompasses any aromatherapy method that delivers the medicinal properties of essential oils and other substances through the dermal and respiratory systems. Aromatherapy is used through massage, inhalation, hot compresses, soaking, and steaming, allowing the essential oils and fragrances to quickly absorb into the bloodstream and lymph, thereby accelerating metabolism, promoting cell regeneration, enhancing immunity, and regulating the nervous, circulatory, and endocrine systems.

[0003] Traditional aromatherapy vessels are mostly made of glass, metal, or white porcelain, lacking the classical charm of Chinese tradition. Black pottery, a key ancient Chinese ceramic art style, boasts a dense texture, a calming color, and a simple, quaint shape, possessing both high artistic value and practical performance. However, few products currently combine black pottery with aromatherapy functions, and traditional aromatherapy devices offer poor air purification effectiveness. Therefore, developing a black pottery aromatherapy vessel is of great practical significance. Summary of the Invention

[0028] The inner wall of the pot of the present invention adopts high-temperature phase-change ceramic microspheres + transparent ceramic sol coating, which not only improves the heat storage and heat release capacity of the pottery, but also can stably release negative ions, with the functions of purifying the air, enhancing the aromatherapy effect, and slowly releasing the fragrance. The aromatherapy pot is equipped with a detachable hollow porous ceramic core module. The module structure has good adsorption and breathability. It can be reused or replaced with different fragrances, providing a good user experience, economy and durability. The 3D printing / molded ceramic core design achieves precise pore control and optimized airflow, effectively improving the aroma diffusion rate and coverage, and enhancing the aromatherapy performance. Traditional black pottery craftsmanship is combined with modern fumigation technology to achieve a good appearance and texture. The traditional wood-fired, electric furnace + reducing atmosphere fumigation technology gives the pottery a natural metallic luster black effect. A smooth and moist appearance can be obtained without adding glaze, combining artistry and practicality. The natural antibacterial plant film layer improves hygiene and aesthetics. The surface of the vessel is treated with plant extracts (such as mugwort and perilla) to form a natural antibacterial coating with additional functions such as antibacterial, deodorization, and extending the shelf life of spices.
