Description

Technical Field

[0001] The present invention belongs to the technical field of temperature regulating systems, and in particular relates to a brace-type knitted fully-formed air duct structure for regulating temperature and a manufacturing method thereof. Background Art

[0002] Existing wearable thermal management systems include devices with cooling or heating modules and clothing made of special materials or structures. In a thermoneutral steady-state environment, some people still feel uncomfortable. By locally heating or cooling various parts of the human body, thermal comfort can be improved over a wider temperature range and energy consumption can be reduced. At the same time, personalized temperature control devices make it easier for users to control their own thermal environment and meet individual needs, thereby improving thermal satisfaction at the physiological and psychological levels.

[0003] In order to achieve the temperature control effect in different areas, there are different temperature control methods. For the temperature control of areas with smaller surface areas such as the head, neck, and hands, liquids and thermoelectric devices are mostly used. For clothing cooling systems that mainly control the temperature of the torso, cooling fans, phase change materials, and special fabric materials are mostly used. However, most of these local temperature control devices are suitable for specific environments and have serious restrictions and limitations on use. For example, liquid attachments and connecting water pipes limit the range of activities of people and form obstacles to movement; the effective use time of phase change materials is short and difficult to replace; the use conditions of special fabrics are strict and not practical enough; air ventilation suits are very bulky during operation. Therefore, it is necessary to find more flexible and convenient individual wearable temperature control devices to improve human thermal comfort.

[0004] However, existing heat and cold regulation clothing is usually a complete garment rather than an independent accessory. In addition, existing air ventilation clothing delivers gas through ventilation ducts to achieve cooling. When the gas enters the duct, it will cause the duct to expand, thereby deforming the overall structure of the clothing. This deformation restricts the wearer's freedom of movement, especially in high-intensity work environments, affecting operational flexibility. In addition, the duct must be sewn into the work clothes, and the limitations of traditional sewing technology will also cause problems. Possible weaknesses at the seams will affect the stability and durability of the overall structure and increase discomfort when wearing. In addition, traditional cooling / heating clothing usually uses a multi-layer duct system, resulting in uneven distribution of cold / heat. Summary of the invention

[0005] In view of this, in order to solve the problem that the existing air ventilation clothing is designed as a complete garment, and the air duct may expand after the gas enters, thereby deforming the overall structure of the clothing and limiting the freedom of movement of the wearer. In addition, the air duct must be sewn into the work clothes, and the possible weaknesses at the seams will affect the stability and durability of the overall structure, and it is impossible to achieve effective and precise cooling or warmth preservation, the present invention proposes a brace-type knitted fully-formed air duct structure for regulating temperature and a manufacturing method thereof.

The brace-type knitted fully formed air duct structure for regulating temperature adopts an integrated knitting process for the brace, and a cavity is formed between the inner layer and the outer layer of the brace by adopting different knitting methods for the inner layer and the outer layer of the brace. All the coils of the brace are woven from two kinds of yarns, low-melting-point fiber and skin-friendly cotton fiber. The low-melting-point fiber is melted by heating, so that the fiber gaps are tightly combined, which can achieve the effect of shaping the cavity and the vent group and can block the gaps between the coils of the brace, thereby maintaining the shape stability of the brace and ensuring the smooth and uniform distribution of gas flow, avoiding the deformation problem of the existing air ventilation clothing caused by the expansion of the duct, and adopting the brace structure instead of the complete clothing can improve the wearer's flexibility.

The gas is evenly distributed in the cavity, and the gas is guided to different parts of the human body, and then flows out through the vent group. The surface of the human body is cooled or warmed through convection heat exchange or hot air insulation. The gas after cooling or heating the human body flows out through the cuffs, collars or gaps in the fabric of the clothing, and the cycle is repeated to achieve human body temperature regulation. The brace-type knitted fully formed air duct structure for regulating temperature can achieve effective and precise cooling or warming by designing the vent group at the key parts that need cooling or warming.

[0027] 4. The present invention provides a brace-type knitted fully formed duct structure for regulating temperature and a manufacturing method thereof.

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely explain the technical solutions in the embodiments of the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict, and the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0053] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0055] In the description of this embodiment, the terms "upper", "lower", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0056] See also Figure 1-12 To describe this embodiment, the present invention provides a brace-type knitted fully formed air duct structure for regulating temperature and a manufacturing method thereof, wherein the brace-type knitted fully formed air duct structure for regulating temperature comprises a brace structure, a connecting tube and a thermoelectric device, wherein the brace structure comprises a brace 1, wherein the brace 1 adopts an integrated knitting process, wherein the inner layer 5 of the brace and the outer layer 6 of the brace adopt different knitting methods to form a cavity 7 between the inner layer 5 of the brace and the outer layer 6 of the brace, and the brace 1 is provided with a vent group, and the cavity 7 is connected to the outside through the vent group; all the coils of the brace 1 are woven from two kinds of yarns, a low-melting-point fiber 9 and a skin-friendly cotton fiber 8, and one end of the connecting tube is connected to the cavity 7, and the other end is connected to the thermoelectric device.

[0057] In the brace-type knitted fully formed air duct structure for regulating temperature, the thermoelectric device draws air from the surrounding environment and performs cooling or heating treatment, and then enters the connecting tube, and then is transmitted to the cavity 7 of the brace 1 through the connecting tube. The gas is evenly distributed in the cavity 7, and the gas is guided to different parts of the human body, and then flows out through the vent group, and the surface of the human body is cooled or warmed through convection heat exchange or hot air insulation. The gas after the human body is cooled or heated flows out through the cuffs, collars or fabric gaps of the clothing, and the cycle is repeated to achieve human body temperature regulation. The brace-type knitted fully formed air duct structure for regulating temperature can achieve effective and precise cooling or warming by designing the vent group at the key parts that need cooling or warming. The brace 1 adopts an integrated knitting process, and the inner layer 5 of the brace and the outer layer 6 of the brace are knitted in different ways to form a cavity 7 between the inner layer 5 and the outer layer 6 of the brace. All the coils of the brace 1 are woven from two kinds of yarns, low-melting-point fiber 9 and skin-friendly cotton fiber 8. The low-melting-point fiber 9 is melted by heating, so that the fiber gaps are tightly combined, which can achieve fiber bonding and enhance structural strength, thereby achieving the effect of shaping the cavity 7 and the vent group and blocking the gaps between the coils of the knitted brace 1, which not only maintains the shape stability of the brace 1, but also ensures the smooth and uniform distribution of gas flow, avoiding the deformation problem caused by the expansion of the pipeline in the existing air ventilation suit, and adopting a brace structure instead of a complete garment can improve the wearer's flexibility. In addition, the brace 1 adopts an integrated knitting process, which avoids the defects caused by the sewing process, improves stability and durability, and increases the comfort when wearing. Therefore, the bib-type knitted fully formed air duct structure for regulating temperature can achieve precise cooling or warmth preservation, achieve efficient temperature regulation effect, and improve the wearer's flexibility and comfort.

[0058] Moreover, the brace-type knitted fully-formed duct structure for regulating temperature adopts an integrated knitting process for the brace 1, which avoids the problem of liquid attachments and connecting water pipes restricting the range of movement of people and forming movement obstacles. In addition, the knitted brace structure not only reduces the weight of the overall clothing, but also forms a ventilation hole group through the circle transfer process, which effectively improves the gas circulation effect, thereby achieving efficient cooling or warming effects and a portable wearing experience.

[0059] It can be understood that the thermoelectric device is composed of a thermoelectric module, a heat sink on the air supply side, a heat sink on the air exhaust side, a micro blower on the air supply side, and an axial fan on the air exhaust side, which are then installed together in a 3D printed plastic housing. The thermoelectric module can cool or heat the ambient air, which is transmitted into the cavity 7 of the shoulder strap 1 through the connecting pipe, and then flows out through the vent group, contacts the human skin, and the gas exchanges heat with the skin.

[0060] It is understandable that the melting point of the low-melting point fiber 9 is lower than the melting point of the skin-friendly cotton fiber 8. When the heating temperature reaches the melting point of the low-melting point fiber 9, the low-melting point fiber 9 will melt, while the skin-friendly cotton fiber 8 will not melt. The shaping can be completed without affecting the performance of the main material, ensuring the functionality and service life of the strap 1.

[0061] The brace-type knitted fully formed air duct structure for regulating temperature can also be used with work clothes. First, wear the brace-type knitted fully formed air duct structure for regulating temperature, and then put on the work clothes outside the brace 1. At this time, the gas enters the work clothes through the vent group, and a gas flow layer is formed between the work clothes and the skin. This gas flow layer uses the principle of convection heat transfer or hot air insulation to achieve the effect of cooling or warming. The air circulation is discharged through the cuffs, collars or other gaps of the work clothes, ensuring the continuity and stability of temperature regulation, and improving the comfort and practicality during use.

[0062] In this embodiment, the connecting tube is a threaded silicone tube.

[0063] Optionally, the inner layer 5 of the brace adopts a rib knitted structure, and the outer layer 6 of the brace adopts a plain knitted structure. The outer layer 6 of the brace adopts a plain knitted structure, which can maintain a relatively flat fabric surface and ensure structural strength, while the inner layer 5 of the brace adopts a rib knitted structure. Since the rib knitting has a strong shrinkage, the inner layer 5 of the brace can fit the surface of the human body more closely. On the premise of ensuring that the number of coils of the inner layer 5 of the brace and the outer layer 6 of the brace are the same, the rib shrinkage of the inner layer 5 of the brace will cause the plain weave of the outer layer 6 of the brace to arch up, forming a cavity 7 with a semicircular cross-section, which can ensure that the gas can flow freely in the cavity 7, thereby enhancing the cooling or warming effect. By combining plain and rib knitting, the shape stability of the brace 1 is maintained, and the smooth flow of gas is ensured. Then, through the shaping effect of the low-melting-point fiber 9 after heating, better structural strength and gas diversion effect are provided, ensuring that the gas can be evenly distributed.

[0064] Optionally, the strap structure further includes a buckle 10, which includes a male buckle and a female buckle that can be plugged in and matched; the strap 1 includes a waist strap 11, a back strap 12, two shoulder straps 13 and two front chest straps 14, the lower end of the back strap 12 is woven with the middle of the waist strap 11, the upper end of the back strap 12 is woven with the two shoulder straps 13, the two shoulder straps 13 are woven with the two front chest straps 14, one end of the front chest strap 14 and the waist strap 11 are both connected to the male buckle, and the other end of the other front chest strap 14 and the waist strap 11 are both connected to the female buckle. The convenient design of the buckle 10 greatly simplifies the process of putting on and taking off, and enhances the practicality of the strap-type knitted fully molded air duct structure for regulating temperature. After entering the strap 1 from the connecting pipe, the gas is divided into three paths, two of which extend to the two ends of the waist strap 11 respectively, and one path extends upward along the back strap 12, and then enters the shoulder strap 13 and the front chest strap 14.

[0065] like Fig.11 and Fig.12 As shown, the upper end of the back strap 12 is divided into two parts, and the upper ends of the back strap 12 are woven together with the two shoulder straps 13, and the lower end of the back strap 12 is divided into three parts, and the lower ends of the back strap 12 are connected to the waist strap 11 and the connecting pipe respectively. Fig.12 In the figure, the triangular area is the area where the needles are not moved, that is, the area where no knitting is performed, and the area with the line with an arrow is the area where the needles are moved, that is, the area where knitting is performed.

[0066] Optionally, the vent group includes a plurality of waist and abdomen vents 21, a plurality of back vents 22, a plurality of neck vents 23 and a plurality of chest vents 24, wherein the waist and abdomen vents 21 are arranged on the waist belt 11, the back vents 22 are arranged on the back belt 12, the neck vents 23 are arranged on the shoulder belt 13, and the chest vents 24 are arranged on the front chest belt 14. Usually, the back, neck, abdomen, chest and waist of the human body are more sensitive to cold and heat. Ventilation holes are reasonably arranged in specific areas such as the back, neck, chest and abdomen, which are more sensitive to cold and heat, so as to achieve precise cooling or warming, and effectively enhance the cooling or warming effect. It is understandable that the gas blown out from the waist and abdomen vents 21, the back vents 22, the neck vents 23 and the chest vents 24 can reach the waist and abdomen, back, neck and chest respectively.

[0067] Optionally, the strap structure further includes two front adjustment components and two waist adjustment components, the front adjustment component includes a connected front adjustment buckle 4 and a front adjustment belt, the two front chest belts 14 are fixedly connected to the two front adjustment belts, and the two front adjustment buckles 4 are slidably mounted on the two front chest belts 14; the waist adjustment component includes a connected waist adjustment buckle 3 and a waist adjustment belt, the two waist adjustment belts are fixedly connected to the two ends of the waist belt 11, and the two waist adjustment buckles 3 are slidably mounted on the waist belt 11. The wearer can adjust the tightness of the strap 1 by adjusting the positions of the front adjustment buckle 4 and the waist adjustment buckle 3, so as to provide a flexible adjustment space, ensuring that the wearer can easily adjust the tightness of the strap 1 as needed.

[0068] In this embodiment, the distance between the front adjustment buckle 4 and the waist adjustment buckle 3 and the insertion buckle 10 is 10 cm-15 cm.

[0069] Optionally, the front adjustment belt and the waist adjustment belt are both made of skin-friendly cotton fiber 8. The knitted fabrics of the front adjustment belt and the waist adjustment belt are not added with low-melting-point fiber 9.

[0070] Optionally, the waist and abdomen vents 21, the back vents 22, the neck vents 23 and the chest vents 24 are all formed by a knitting transfer process. Optionally, among the waist and abdomen vents 21, the back vents 22, the neck vents 23 and the chest vents 24, the back vents 22 have the largest size. The sizes of the waist and abdomen vents 21, the back vents 22, the neck vents 23 and the chest vents 24 are precisely adjusted according to the needs of different parts. The back vents 22 have the largest size to enhance the circulation of gas in this area to ensure efficient cooling or warmth. The waist and abdomen vents 21, the neck vents 23 and the chest vents 24 are relatively evenly distributed in size to ensure that the gas can flow evenly throughout the body, further optimizing the overall cooling or warmth effect, and providing a more comfortable and lasting cooling or warmth experience.

[0071] The brace-type knitted fully formed air duct structure for adjusting temperature can realize convenient temperature control and improve the comfort of the wearer in various working environments. When in use, the wearer first wears the brace 1 on the body through the buckle 10, and easily adjusts the tightness of the brace 1 using the front adjustment buckle 4 and the waist adjustment buckle 3 to ensure a close fit with the body. After wearing, the wearer connects the thermoelectric device and the connecting tube to the brace 1 and starts the thermoelectric device. The gas will be directed to specific parts of the body, such as the back, neck, chest and abdomen, through the vent group on the brace 1. According to actual needs, the wearer can choose the cold air or warm air mode and flexibly adjust the temperature to achieve the best wearing experience. When wearing work clothes, the brace 1 is worn inside the work clothes, and the gas enters the inside of the work clothes through the vent group, forming a sandwich cold and hot cycle. This circulation system effectively promotes convective heat exchange or hot air insulation, thereby quickly adjusting the body temperature and ensuring that the wearer can remain comfortable under various working conditions. After use, the wearer should turn off the thermoelectric device and disconnect the connecting tube to complete the entire temperature regulation process.

[0072] The present invention also provides a method for manufacturing a brace-type knitted fully-fashioned air duct structure for regulating temperature, which is used to manufacture the brace-type knitted fully-fashioned air duct structure for regulating temperature, and specifically comprises:

[0073] The two yarns, low-melting-point fiber 9 and skin-friendly cotton fiber 8, are combined and woven by adding yarn, so that each coil of the shoulder strap 1 is composed of the two yarns, low-melting-point fiber 9 and skin-friendly cotton fiber 8.

[0074] like Figure 7 As shown, the inner layer 5 of the strap is made of rib knitting technology, such as Figure 6 As shown, the outer layer 6 of the strap is knitted using a plain weave process. Under the premise of ensuring that the number of coils of the inner layer 5 and the outer layer 6 of the strap are the same, the shrinkage of the ribbing of the inner layer 5 of the strap will cause the plain weave of the outer layer 6 of the strap to bulge, thereby forming a cavity 7 between the inner layer 5 and the outer layer 6 of the strap.

[0075] Specifically, it is recommended to use an 18G model, i.e., 18 needles / 1 inch, through a computerized flat knitting machine, and adopt a combination of plain and ribbed stitches to achieve the structural difference between the outer layer 6 of the strap and the inner layer 5 of the strap, thereby forming a cavity 7. Specifically, the outer layer 6 of the strap adopts a plain knitting process, while the outer layer 6 of the strap adopts a ribbed knitting process. Since the ribbed stitch has strong shrinkage, on the premise of ensuring that the number of coils of the inner layer 5 of the strap and the outer layer 6 of the strap are the same, the ribbed shrinkage of the inner layer 5 of the strap will cause the plain weave of the outer layer 6 of the strap to bulge, forming a cavity 7 with a semicircular cross-section, ensuring that the gas can flow freely in the cavity 7, thereby enhancing the cooling or warming effect.

[0076] A group of ventilation holes is left on the shoulder strap 1 by adopting the transfer process. Through precise knitting structure design, holes are cleverly set without destroying the overall strength of the fabric to achieve effective distribution of gas. In order to improve the accuracy and efficiency of the cooling or warming effect, the air in the environment is cooled or heated by a thermoelectric device, supplied to the human body through a fan and a connecting pipe, and transported from the back to the top. The back is the main heat dissipation area, especially around the spine and shoulder blades. Therefore, the size of the back vents 22 is specially increased in the back area, especially in the spine and shoulder blade areas. The transfer process is used to optimize the airflow distribution, which can significantly enhance the effect of local temperature regulation, thereby effectively affecting the overall comfort, making the human body more aware of temperature changes during cooling or warming, thereby improving overall comfort. The back vents 22 are made of the following: Figure 8 The waist and abdomen vents 21, the neck vents 23 and the chest vents 24 are formed by the transfer process shown in FIG. Fig. 9 The holes formed by the transfer process shown above can balance the appropriate air output and wearing comfort. The ventilation hole group formed by the transfer process optimizes the directional distribution and circulation efficiency of the airflow, ensuring that the air can achieve precise cooling or warming functions in different parts of the human body.

[0077] The strap 1 is heated to melt the low-melting point fiber 9 in the strap 1, so as to achieve the shaping of the cavity 7 and the vent group. In the knitted structure, the low-melting point fiber 9 is added and the strap 1 is shaped in combination with the heating process, so as to ensure that the formed cavity 7 and the vent group have excellent stability and durability. The overall fabric is made of skin-friendly cotton, and its melting point is about 200°C, which ensures the durability and comfort of the fabric. The melting point of the low-melting point fiber 9 is about 130°C, and its melting characteristics play an important role in the manufacturing process. Through appropriate heat treatment, such as hot air, infrared and electric heating, the low-melting point fiber 9 begins to melt at a melting point of 130°C, so that the fiber gaps are tightly combined, thereby stabilizing the structure of the arched cavity 7, and at the same time, the gaps between the coils of the knitted structure are closed. The addition of low-melting point fiber 9 optimizes the stability of the fabric and improves the cooling or warming effect. Due to the melting characteristics of the low-melting-point fiber 9, the complexity of the later processing is reduced and the production efficiency is improved, which makes the strap structure more comfortable and durable to wear and simplifies the production process.

[0078] Optionally, the shoulder strap 13 of the shoulder strap 1 adopts a local weaving process. During the knitting process of the shoulder strap 13, the tension of the shoulder strap 13 is reduced by reducing the number of coils of the shoulder strap 13 or adjusting the needle distribution of the shoulder strap 13, thereby achieving the bending and three-dimensionalization of the shoulder strap 13. The shoulder strap 13 is realized by local weaving molding technology, which can be adjusted according to the shape and needs of the shoulder. While maintaining the ventilation function, it can also adapt to the curve of the shoulder and enhance the wearing comfort. By reducing the number of coils of the shoulder strap 13 or adjusting the needle distribution of the shoulder strap 13, the tension of the shoulder strap 13 is reduced, thereby achieving the bending and three-dimensionalization of the shoulder strap 13. This technology not only allows the knitted fabric to better adapt to the shape of the shoulder and improves the wearing comfort, but also ensures the ventilation and fluidity of the gas in the shoulder area, further improving the overall functionality and comfort of the bra-type knitted fully molded duct structure for regulating temperature. Fig.10 As shown, the triangular areas on both sides of the figure represent non-knitting areas, that is, areas where needles are not moved, and the areas with arrow lines represent knitting areas, that is, areas where needles are moved.
