Description

Technical Field

[0001] This invention relates to a desiccant, specifically a composite desiccant that combines highly efficient moisture absorption with an active release of natural anti-mildew formula, suitable for environments requiring humidity control and inhibition of microbial growth. Background Technology

[0002] Traditional desiccants mainly consist of materials such as silica gel, quicklime, calcium chloride, or montmorillonite. While these desiccants possess good moisture absorption properties, their application has several significant drawbacks: First, most traditional desiccants cannot effectively decompose in the natural environment after use, leading to long-term accumulation and soil and water pollution, posing a potential threat to ecosystems; second, some desiccants are corrosive or toxic, posing health risks if ingested or come into contact with skin; third, traditional desiccants only have a single moisture absorption function and lack the ability to inhibit the growth of mold and bacteria, making them ineffective in addressing the problem of rapid microbial proliferation in humid environments.

[0003] In recent years, with increasing global emphasis on environmental sustainability, governments worldwide have enacted stricter environmental regulations, restricting the use of non-biodegradable materials and harmful chemicals. Consumers are also increasingly inclined to choose safe, natural, and recyclable environmentally friendly products. While some desiccants based on natural materials, such as bamboo charcoal, wood chips, and rice husks, have emerged in this context, they often focus solely on moisture absorption and fail to integrate a stable antibacterial release mechanism. Furthermore, some products, while adding chemical preservatives to prevent mold growth, violate the original design principles of being natural and non-toxic, and may create environmental residues, which is detrimental to long-term ecological balance.

[0004] Therefore, there is an urgent need for a new type of desiccant that can simultaneously achieve the dual functions of "high-efficiency moisture absorption" and "natural anti-mildew and antibacterial properties," and can be processed through natural microbial decomposition or heat regeneration after use, thus achieving the dual goals of environmental friendliness and functional integration, in order to meet the urgent needs of modern society for products with high safety, high functionality and sustainability.

[0037] The following description, in conjunction with the drawings of the preferred embodiments of the present invention, is intended to enable those skilled in the art to implement the invention based on the statements herein.

[0038] like Figures 1 to 7 As shown, this utility model provides a desiccant with dual functions of moisture absorption and anti-mildew formula release, comprising: a first packaging bag 10, a second packaging bag 20, a first desiccant body 30 and a second desiccant body 40.

[0039] The first packaging bag 10 is quadrilateral in shape and is made of a biodegradable breathable material, such as polylactic acid (PLA) or its derivatives, which has high breathability, tear resistance and high moisture absorption efficiency, and has a first accommodating space 11 inside.

[0040] The second packaging bag 20 is quadrilateral in shape and made of biodegradable material, such as polylactic acid (PLA) or its derivatives. It has high breathability, tear resistance and high moisture absorption efficiency. It has a second accommodating space 21 inside and is connected to or integrally formed with the first packaging bag 10. A tear line 50 is provided between the two. The tear line 50 can be a dotted line or a dashed line, so that the user can easily separate the first packaging bag 10 and the second packaging bag 20 along the tear line 50.

[0041] The first desiccant body 30 is disposed within the first accommodating space 11 of the first packaging bag 10. The first desiccant body 30 uses carbonized rice husk 31 as a substrate, and an anti-mold formula essential oil 32 is uniformly coated or impregnated on the carbonized rice husk 31. The carbonized rice husk 31 is obtained by carbonizing rice husks under oxygen-deficient or oxygen-limited conditions at high temperatures of 600°C to 900°C. This high-temperature carbonization process not only removes volatile organic compounds from the rice husks but also forms a rich microporous structure and large pores on its surface and inside, resulting in a porosity of up to 200-500 μm. 2 With a specific surface area of ​​ / g, it significantly enhances the adsorption capacity for ambient moisture, exhibiting highly efficient moisture absorption performance.

[0042] Furthermore, the carbonized rice husk 31 also serves as a carrier for the anti-mold formula essential oil 32. Through the capillary action of its porous structure, the anti-mold formula essential oil 32 is adsorbed and stably stored within the pores of the carbonized rice husk 31. Due to this structural characteristic, the essential oil components are slowly and continuously released into the surrounding environment via gaseous diffusion, exerting anti-mold and antibacterial effects. Preferably, the anti-mold formula essential oil 32 uses natural plant extracts, such as catechins, mustard or chili extracts, and peppermint extract, which are highly safe and have good antibacterial effects, especially showing significant inhibitory effects against microorganisms that easily grow in humid environments, such as molds, yeasts, and bacteria.

[0043] The second desiccant body 40 is disposed within the second accommodating space 21 of the second packaging bag 20. It is composed of a molecular sieve 41 with a porous structure, used to efficiently adsorb water molecules from the environment, achieving deep dehumidification. Preferably, the molecular sieve 41 is an A4 molecular sieve (pore size approximately...). This molecular sieve effectively adsorbs water molecules while excluding other gas molecules, possessing an extremely high specific surface area and excellent moisture absorption capacity, making it suitable for precision moisture protection needs in low-humidity environments. It should be understood that the type of molecular sieve 41 is not limited to 4A molecular sieve; 3A molecular sieve or other molecular sieve materials with similar moisture absorption properties can also be selected, depending on the actual application requirements.

[0044] In this embodiment, the first packaging bag 10 is permeable to moisture but prevents the contents from escaping. It allows external moisture to effectively penetrate and be absorbed by the first desiccant body 30. At the same time, it effectively prevents the internal carbonized rice husk 31 and anti-mold formula essential oil 32 from leaking or escaping, ensuring stable material storage. Similarly, the second packaging bag 20 also has high moisture permeability, allowing moisture to enter smoothly and be absorbed by the second desiccant body 40, while effectively preventing leakage of the molecular sieve 41. This achieves an optimal balance between high moisture absorption efficiency and stable material storage, balancing moisture absorption efficiency with structural reliability.

[0045] The first desiccant body 30 and the second desiccant body 40 can be used independently or in combination as needed. In high-humidity environments where mildew prevention and deodorization are also required, it is recommended to use the first packaging bag 10 and the second packaging bag 20 simultaneously to achieve a synergistic effect and improve the overall moisture absorption, antibacterial, and odor control performance. If only antibacterial and fragrance functions are required, the first packaging bag 10 can be separated along the tear line 50 for individual use, improving application flexibility and ease of use.

[0046] In another embodiment, such as Figure 8As shown, the molecular sieve 41 is not only used to efficiently adsorb water molecules in the environment to achieve deep dehumidification, but also, through technical control, adsorbs a predetermined weight percentage of anti-mold formula essential oil 42, and releases the anti-mold formula essential oil 42 stably and slowly through its pore structure, in order to work synergistically with the first desiccant body 10 to provide more comprehensive anti-mold and antibacterial protection.

[0047] The anti-mold formula essential oil 42 adsorbed by the molecular sieve 41 accounts for 5% to 30% of the total weight of the molecular sieve 41. The molecular sieve 41 adsorbs the anti-mold formula essential oil 42 by impregnation, spraying or chemical bonding.

[0048] The following benefits can be obtained from the structure of the above specific embodiments:

[0049] 1. This utility model is a desiccant with dual functions of moisture absorption and anti-mold formula release. In addition to moisture absorption, the first desiccant body 30 can also release anti-mold formula essential oil 32 to effectively inhibit mold growth. The second desiccant body 40 provides efficient dehumidification and significantly reduces environmental humidity. The two functions work together to show a comprehensive protective effect that is far superior to traditional single-function desiccants.

[0050] 2. This utility model is a desiccant with dual functions of moisture absorption and anti-mildew formula release. Its first desiccant body 30 is made from agricultural waste (carbonized rice husk 31) as raw material, which has renewable and natural decomposition characteristics. After use, it can be returned to the soil as organic fertilizer, which greatly reduces the environmental burden. The second desiccant body 40 is made of molecular sieve, which has excellent moisture absorption and regeneration capabilities. It can be repeatedly activated and used by heating, which extends the product life. The overall design integrates the concepts of ecological cycle and circular economy, taking into account environmental protection and long-term use benefits, which is in line with the trend of modern sustainable development.
