Description

Technical Field

[0001] This utility model mainly relates to the field of down comforters, specifically to a mite-proof down comforter. Background Technology

[0002] In recent years, with the increasing demand for better sleep quality and a healthier lifestyle, down comforters have gradually become the mainstream choice in the home bedding market due to their lightweight warmth and excellent breathability. However, traditional down comforters face a significant problem in actual use: their filling (down and feathers) combines with shed skin flakes, sweat, and other metabolic waste, easily creating a breeding ground for dust mites in warm and humid environments. Dust mites and their excrement can not only cause health problems such as allergic rhinitis and asthma, but also lead to clumping of the comforter core and unpleasant odors, seriously affecting the product's lifespan and user experience.

[0003] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," "fixed," "provided with," and "located in" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0026] See attached document Figure 1-4 A mite-proof down comforter includes a down comforter structure 1, wherein an inflatable structure 2 is provided on one side of the down comforter structure 1.

[0027] The inflatable structure 2 includes a connecting strip 201, which is disposed on the outer wall of the down comforter structure 1. A side cover 202 is provided on one side of the connecting strip 201, and a sealing block 203 is provided at the bottom of the side cover 202. At the same time, the connecting pipe 107 can be opened periodically, and then the air outlet of the air pump or other inflatable device can be inserted into the interior of the connecting pipe 107. Then, the air pump or other inflatable device is started, so that the gas can enter the interior of the down storage chamber 103. The gas is blocked by the filter baffle 106, so that the gas comes into contact with the down body 104 and disperses the down body 104.

[0028] Furthermore, the down comforter structure 1 includes a down comforter body 101, an air chamber 102 is provided inside the down comforter body 101, a down placement chamber 103 is provided inside the air chamber 102, the down placement chamber 103 is filled with down body 104, and the number of down placement chambers 103 is set to multiple, the multiple down placement chambers 103 are evenly distributed inside the down comforter body 101, a connecting groove 105 is provided between two down placement chambers 103, a filter baffle 106 is provided inside the connecting groove 105, the filter baffle 106 is arc-shaped, the filter baffle 106 is provided on both sides of the inner wall of the connecting groove 105, the multiple down placement chambers 103 are connected by a connecting pipe 107, the inner wall of the connecting pipe 107 is attached to the outer wall of the sealing block 203, the down comforter body 101 and the air chamber 102 are mainly composed of an outer anti-mite breathable fabric and an intermediate antibacterial isolation layer;

[0029] The outer mite-proof and breathable fabric is made of high-density pure cotton and polyester fiber blended fabric. Through nano-weaving technology, a physical barrier layer with a pore size of ≤10 microns is formed, which can block adult mites with a body length of 100-400 microns and their excrement with a particle size of ≥20 microns from penetrating. At the same time, the microporous structure on the fiber surface with a pore size of 1-3 microns maintains breathability and avoids stuffiness.

[0030] The middle antibacterial isolation layer adds a barrier mesh made of natural plant fibers such as bamboo charcoal fiber and flax fiber between the down filling and the outer fabric. Utilizing the antibacterial and moisture-absorbing properties of the fibers themselves, the bamboo charcoal fiber has an adsorption rate of ≥90%, reducing dander and sweat residue and cutting off the food source for mites.

[0031] After the down feather body 104 is thoroughly cleaned by supercritical CO2 cleaning process to remove grease and impurities, a composite anti-mite coating composed of chitosan natural antibacterial agent and eucalyptus essential oil microcapsules with a particle size of 50-200nm is sprayed on to achieve a slow-release anti-mite effect with a continuous release period of ≥2 years.

[0032] Furthermore, eucalyptus oil, citronellal, and other natural mite-repelling ingredients are encapsulated in biodegradable polylactic acid (PLA) microcapsules inside the down body 104 and the down comforter body 101. These microcapsules are then fixed to the fabric fibers and the surface of the insulating layer using an electrospinning process to prevent direct contact with the human body. The microcapsules slowly release the active ingredients when subjected to friction or changes in temperature and humidity, with a release rate ≤0.5 mg / day·m², thus extending the mite-proof period.

[0033] Synergistic mechanism of physical barrier and biological anti-mite: Through the pore size graded design of the outer layer for mite blocking, the middle layer for antibacterial, and the slow-release technology of natural anti-mite ingredients, the conditions for mite breeding are reduced from the source, breaking through the limitations of single anti-mite technology.

[0034] Microcapsule-guided sustained release: PLA microcapsules are used to control the release rate of natural anti-mite ingredients, solving the problems of easy volatility and short shelf life of traditional natural ingredients, resulting in long-lasting and stable anti-mite effects;

[0035] Down surface modification: Supercritical cleaning + plasma grafting process to achieve deep cleaning and mite-proofing of down, avoid filling caking and maintain loft.

[0036] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
