Description

Technical Field

[0001] This utility model relates to the field of underwear technology, and in particular to a breathable underwear. Background Technology

[0002] In modern life, underwear, as clothing worn close to the skin, directly affects the wearer's comfort and health. Good breathability allows sweat and heat to escape quickly, preventing bacterial growth and reducing the occurrence of skin diseases.

[0003] Currently, most underwear on the market uses flat breathable mesh or perforated structures to achieve moisture wicking. For example, the lateral breathable structure underwear disclosed in Chinese utility model patent CN222869891U achieves lateral breathability by setting a breathable membrane in the interlayer. This structure solves the breathability problem of underwear to a certain extent. However, when the wearer engages in strenuous exercise and their body temperature rises rapidly, this type of breathable structure lacks a dynamic adjustment mechanism and cannot increase the breathable space according to the actual needs of the human body. This results in insufficient air exchange, and sweat and heat cannot be discharged in time, causing the wearer to experience stuffiness, dampness, and other discomforts, affecting the exercise experience and physical health. This technical solution still has considerable room for improvement. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a breathable underwear.

[0005] A breathable bra designed for this purpose includes a front panel, cups, side panels, back panel, and shoulder straps;

[0006] The cup includes an inner layer, an outer layer, and a breathable support frame. The breathable support frame is disposed between the inner layer and the outer layer, and a three-dimensional exhaust cavity is formed between the inner layer and the outer layer.

[0007] The inner layer is made of breathable material;

[0008] The three-dimensional exhaust chamber contains temperature-sensitive expandable breathable columns, which are fitted together with the inner layer.

[0009] Preferably, a connecting piece is provided between two adjacent temperature-sensitive expandable breathable columns to connect them.

[0010] Preferably, a connector is provided on some of the temperature-sensitive expandable breathable columns to be fixedly connected to the breathable support frame.

[0011] Preferably, the temperature-sensitive expandable breathable column, connecting piece, and connector are all made of temperature-sensitive SMP material.

[0012] Preferably, the breathable support frame is made of food-grade silicone, and the breathable support frame is provided with evenly distributed air vents.

[0013] Preferably, the front sheet and the side sheet are composed of graphene-modified skin-friendly cotton, a honeycomb elastic support layer, and a microporous polyurethane membrane in sequence.

[0014] Compared with existing technologies, this breathable underwear, through its unique structural design, effectively overcomes the shortcomings of existing technologies and has significant beneficial effects. The breathable support frame set in the cups creates a three-dimensional ventilation chamber between the inner and outer layers. Compared with traditional planar breathable structures, its three-dimensional space provides a wider channel for the expulsion of heat and moisture, greatly improving basic breathability. The inner layer is made of breathable material, ensuring airflow in the parts in direct contact with the skin, further enhancing the dryness of the wearer. Crucially, the temperature-sensitive expandable breathable columns distributed within the three-dimensional ventilation chamber fit snugly against the inner layer. When the wearer's body temperature rises during strenuous exercise, the temperature-sensitive expandable breathable columns expand due to heat, automatically increasing the internal space of the three-dimensional ventilation chamber, dynamically adjusting the airflow, significantly increasing ventilation, and promptly expelling sweat and heat. When the body temperature returns to normal, the breathable columns contract, maintaining a moderately breathable state. This design enables intelligent dynamic adjustment of breathability, always creating a dry and comfortable wearing environment for the wearer, effectively improving the experience of sports and daily wear, while reducing the risk of skin problems caused by stuffiness and dampness.

[0026] See Figure 1 and Figure 3A breathable bra includes a front piece 10, a cup 20, side panels 30, a back piece 40, and shoulder straps 50. The cup 20 includes an inner layer 210, an outer layer 220, and a breathable support frame 230. The breathable support frame 230 is disposed between the inner layer 210 and the outer layer 220, forming a three-dimensional ventilation cavity 200 between the inner layer 210 and the outer layer 220. The inner layer 210 is made of a breathable material. Temperature-sensitive expandable breathable columns 240 are distributed in the three-dimensional ventilation cavity 200, and the temperature-sensitive expandable breathable columns 240 are fitted to the inner layer 210.

[0027] In the overall structure of the underwear, the inner layer 210 of the cups is made of breathable material, allowing heat and moisture generated on the skin surface to quickly pass through the material into the three-dimensional ventilation cavity 200. The breathable support frame 230, forming the three-dimensional ventilation cavity 200 between the inner layer 210 and the outer layer 220, creates a more efficient gas flow channel compared to traditional planar structures due to its three-dimensional spatial characteristics, providing a spacious path for the expulsion of moisture and heat. Thermosensitive expandable breathable columns 240, distributed within the three-dimensional ventilation cavity 200, fit snugly against the inner layer 210, constituting an intelligent adjustment system. When the body is at normal temperature, the thermosensitive expandable breathable columns 240 maintain their initial shape, ensuring the underwear has basic breathability. When the wearer engages in strenuous exercise and their body temperature rises, the thermosensitive expandable breathable columns 240 sense the temperature change and expand upon heating, thereby increasing the internal space of the three-dimensional ventilation cavity 200, further widening the gas flow path, significantly increasing ventilation, and allowing accumulated sweat and heat to be quickly expelled to the outside. When body temperature returns to normal, the thermosensitive expandable breathable column 240 contracts, and the three-dimensional exhaust chamber 200 returns to a suitable breathable state, ensuring that the underwear always maintains good and stable breathability, creating a comfortable and dry wearing environment for the wearer.

[0028] like Figure 3As shown, in this invention, a connecting piece 250 is provided between two adjacent temperature-sensitive expandable breathable columns 240 to connect them. The connecting piece 250 has multiple important functions. Firstly, the connecting piece 250 provides stable support, connecting the dispersed temperature-sensitive expandable breathable columns 240 to form a relatively stable overall structure. This prevents the breathable columns from shifting or deforming due to external pressure or friction during daily wear or exercise, ensuring that the temperature-sensitive expandable breathable columns 240 are always in a proper position within the three-dimensional ventilation chamber 200, thus effectively fulfilling their function of temperature-sensitive ventilation regulation. Secondly, the connecting piece 250 helps maintain the structural stability of the three-dimensional ventilation chamber 200. When the temperature-sensitive expandable breathable columns 240 expand when heated or contract when cooled, it works in conjunction with the breathable support frame 230 to prevent irregular changes in the spatial shape of the three-dimensional ventilation chamber 200, ensuring smooth gas flow. In addition, the connecting piece 250 itself can be made of lightweight breathable material. While connecting the breathable columns, it can also assist in the gas exchange process within the three-dimensional ventilation chamber, further improving the overall breathability of the underwear. Working in synergy with other components, it provides the wearer with a more durable and stable dry and comfortable experience.

[0029] In this invention, connectors 260 are provided on some of the temperature-sensitive expandable breathable columns 240 and fixedly connected to the breathable support frame 230. Connectors 260 enhance the fixing effect of the temperature-sensitive expandable breathable columns 240. Compared to relying solely on connecting pieces 250, directly connecting some of the breathable columns to the breathable support frame 230 makes the positioning of the temperature-sensitive expandable breathable columns 240 within the three-dimensional exhaust cavity 200 more stable, effectively resisting various external force interferences during wear, and ensuring that the breathable columns maintain accurate positions during frequent expansion and contraction, thus continuously and stably performing the function of temperature-sensitive ventilation regulation. Secondly, connectors 260 enhance the overall structural reliability of the three-dimensional exhaust cavity 200. When the temperature-sensitive expandable breathable columns 240 change shape due to temperature variations, they work in conjunction with the breathable support frame 230 and connecting pieces 250 to prevent local collapse or deformation of the cavity due to uneven stress, maintaining the regularity of the exhaust cavity's spatial shape and ensuring that gas can always flow along a smooth path. Furthermore, the connector 260 can be made of breathable material. While fixing the components, it also participates in the gas exchange in the three-dimensional ventilation chamber. Working together with components such as the connector 250, it further optimizes the breathability of the underwear, comprehensively improves the wearer's comfort experience during sports and daily life, and effectively avoids problems such as stuffiness and dampness.

[0030] In this invention, the temperature-sensitive expandable breathable column 240, connecting piece 250, and connector 260 are all made of temperature-sensitive SMP material. Using the same material ensures consistent performance response under the same temperature changes. On one hand, the temperature-sensitive expandable breathable column 240 relies on the material's temperature-sensitive properties to expand when heated and contract when cooled, precisely adjusting the air permeability of the three-dimensional exhaust chamber 200. On the other hand, the connecting piece 250 and connector 260 can also undergo slight deformation synchronously with temperature changes, adapting to the shape changes of the breathable column. This avoids stress concentration or structural conflicts caused by differences in material properties, maintaining stable connections between components and the integrity of the overall structure, ensuring the normal operation of the gas flow function of the exhaust chamber.

[0031] In this invention, the breathable support frame 230 is made of food-grade silicone, and the breathable support frame 230 is evenly distributed with ventilation holes 231. This design greatly improves the overall performance of the breathable underwear. Food-grade silicone has extremely high safety, is non-toxic and odorless, and does not easily breed bacteria. It will not cause allergic reactions or other adverse reactions even after prolonged contact with human skin, ensuring the health and safety of the wearer. At the same time, food-grade silicone is soft and elastic, providing stable support for the cups and maintaining the overall shape of the underwear while conforming to the curves of the human body, reducing pressure on the skin and improving wearing comfort. The evenly distributed ventilation holes 231 further enhance the breathability of the underwear. They are interconnected with the three-dimensional ventilation chamber 200, opening up more paths for the expulsion of heat and moisture, accelerating the air circulation speed, and making the breathability effect more significant.

[0032] In this invention, the front panel 10 and side panel 30 are sequentially composited from graphene-modified skin-friendly cotton, a honeycomb elastic support layer, and a microporous polyurethane membrane. The graphene-modified skin-friendly cotton combines the excellent properties of graphene with the soft texture of skin-friendly cotton. Graphene has good thermal conductivity, enabling it to quickly conduct body heat and reduce stuffiness. Simultaneously, its unique antibacterial and bacteriostatic properties effectively inhibit bacterial growth, keeping the inside of the underwear dry and hygienic. The skin-friendly cotton material ensures softness and comfort when in contact with the skin, reducing friction. The honeycomb elastic support layer, with its unique honeycomb structure, provides stable support while possessing good elasticity and extensibility. It conforms to the body's curves, providing auxiliary support for the chest, and adapts to various body movements, avoiding any restriction on movement. The multiple micro-ventilation channels formed within the honeycomb structure further enhance overall breathability. Microporous polyurethane membranes possess excellent breathability and moisture permeability. Their densely packed micropores quickly wick away sweat and moisture, while also providing some wind protection to prevent cold air from directly penetrating, keeping the body warm and comfortable. The combination of these three elements not only achieves an organic integration of breathability, antibacterial properties, support, and comfort, but also gives the front panel and side panels good flexibility while maintaining stronger structural stability, effectively enhancing the overall quality and wearing experience of the underwear.

[0033] In this invention, both the inner layer 210 and the outer layer 220 are made of breathable bubble cotton. Breathable bubble cotton has a unique porous structure; these fine pores form efficient airflow channels, quickly expelling heat and moisture generated by the body while promoting the inflow of fresh air. This significantly enhances the overall breathability of the underwear, effectively preventing discomfort caused by stuffiness and dampness. Its soft and elastic texture allows the underwear to closely conform to the body's curves, reducing skin damage caused by friction from clothing and greatly improving wearing comfort. Furthermore, the breathable bubble cotton, used as the material for the inner layer 210 and the outer layer 220, together with the breathable support frame 230, forms a three-dimensional ventilation cavity 200. This provides a stable working space for components such as the temperature-sensitive expandable breathable column 240. When the temperature-sensitive expandable breathable column 240 expands due to heat or contracts due to cold, the bubble cotton can adapt to changes in the cavity space with its own elasticity and flexibility, ensuring that the three-dimensional ventilation cavity 200 always maintains a good shape and breathability. In conjunction with other structural components such as the front piece 10 and the side panel 30, it comprehensively improves the breathability, comfort, and practicality of the underwear.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
