Description

Technical Field

[0001] This utility model relates to the technical field of fabrics, and more specifically, to an inflatable thermal insulation fabric. Background Technology

[0002] As ambient temperatures drop, people's demands for the warmth of thermal clothing are increasing. Current thermal clothing primarily achieves its insulation effect by using thicker fabrics (such as adding cotton and down fillings) or heat-reflective fabrics. However, thicker fabrics result in overly bulky clothing that is inconvenient to carry, and heat-reflective fabrics, because they can only reflect heat and cannot store it, have limited insulation effectiveness. Furthermore, the fixed sizes of thermal clothing cannot meet the needs of customers requiring multiple sizes. Additionally, in situations where smaller thermal clothing is needed, using larger thermal clothing instead can lead to storage difficulties due to the larger size. Utility Model Content

[0003] The purpose of this invention is to overcome the problem that the size of existing thermal insulation products is fixed and it is difficult to meet the needs of using thermal insulation products of various sizes, and to provide an inflatable thermal insulation fabric.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An inflatable thermal insulation fabric is provided, comprising a fabric body, the fabric body including a closed-structure inflatable layer, the inflatable layer having a plurality of interconnected inflatable cavities formed therein, a first connecting structure and a second connecting structure respectively provided on both sides of the fabric body along a first direction, the first connecting structure and the second connecting structure being adapted to each other; an air inlet structure and an air outlet structure are provided on the inflatable layer, the air inlet structure and the air outlet structure being respectively connected to the inflatable cavities, and the air inlet structure and the air outlet structure being adapted to each other.

[0005] In the technical solution of this application, multiple insulation fabrics can be connected together according to usage requirements to expand the size of the insulation fabric. Specifically, a first connecting structure of one insulation fabric is connected to a second connecting structure of another insulation fabric to expand the size of the insulation fabric. Then, the air outlet structure of one insulation fabric is connected to the air inlet structure of another connected insulation fabric, connecting the internal inflation chambers of multiple insulation fabrics. During inflation, an air pump is connected to the air inlet structure of one side of the insulation fabric, while the air outlet structure of the other side of the insulation fabric is blocked using a sealing structure. The air pump is then started, and gas enters through the air inlet structure. Because the insulation fabrics are interconnected, the inflation of multiple connected insulation fabrics can be completed. After inflation, the air inlet structure is sealed using the sealing structure. In the technical solution of this application, the first and second connecting structures enable the splicing of multiple sheets of insulation fabric, and the air inlet and outlet structures facilitate the connection of the air chambers within the multiple sheets of insulation fabric. Therefore, the insulation fabric of this invention can meet the needs of various sizes of insulation products, and the structure with inflatable air chambers and the ability to splice and disassemble multiple fabric sheets also facilitate storage.

[0006] Furthermore, the inflatable layer has at least a first insulation zone and a second insulation zone, and the first insulation zone and the second insulation zone each have a plurality of inflatable cavities; under the same projected area, the total volume of the inflatable cavities in the first insulation zone is not the same as the total volume of the inflatable cavities in the second insulation zone.

[0007] Furthermore, multiple rows of inflation chambers are arranged along the first direction, and two adjacent inflation chambers in the same row are connected by an air passage. The inflation chambers located at the head of each row are connected by a main pipe. One end of the main pipe is connected to the air inlet structure, and the other end of the main pipe is connected to the air outlet structure.

[0008] Furthermore, some of the adjacent rows of air-filled cavities are located within the second insulation zone.

[0009] Furthermore, among the adjacent rows of air-filled chambers, the multiple air-filled chambers located away from the main pipe are situated in the second insulation zone.

[0010] Furthermore, the air inlet structure and the air outlet structure are arranged along the second direction.

[0011] Furthermore, the main body of the fabric also includes an outer layer and an inner layer that cover and connect to the upper and lower sides of the inflatable layer, respectively, and the first connecting structure and the second connecting structure are respectively connected to both sides of the outer layer along a first direction.

[0012] Furthermore, the inner layer is a heat-reflective fabric, the outer layer is a wear-resistant and scratch-resistant material or a brightly colored material, and reflective markings are provided on the outer layer.

[0013] Furthermore, the first connecting structure and the second connecting structure are respectively one of a zipper structure, a Velcro structure, and a snap fastener structure that can be connected.

[0014] Furthermore, the air inlet structure and the air outlet structure are respectively a plug and a socket that can be connected to each other.

[0015] Compared with existing technologies, the advantages of this invention are as follows: Due to the first and second connecting structures, the insulation fabric of this invention allows for the splicing of multiple sheets of insulation fabric. Furthermore, the air inlet and outlet structures enable communication between the air chambers within the multiple sheets of insulation fabric. Therefore, the insulation fabric of this invention can meet the needs of various sizes of insulation products.

[0020] Example 1 like Figure 1 As shown, an inflatable thermal insulation fabric includes a fabric body 1, which includes an inflatable layer 11 with a closed structure. The inflatable layer 11 has multiple interconnected inflatable cavities 12. The fabric body 1 has a first connecting structure 2 and a second connecting structure 3 respectively arranged on both sides along a first direction. The first connecting structure 2 and the second connecting structure 3 are adapted to each other. The inflatable layer 11 is provided with an air inlet structure 4 and an air outlet structure 5. The air inlet structure 4 and the air outlet structure 5 are respectively connected to the inflatable cavities 12, and the air inlet structure 4 and the air outlet structure 5 are adapted to each other.

[0021] In this embodiment, multiple sheets of insulation fabric can be connected and used together according to usage requirements, thereby increasing the size of the insulation fabric. Specifically, as shown below... Figure 3 , Figure 4As shown, a first connecting structure 2 of one insulating fabric is connected to a second connecting structure 3 of another insulating fabric to expand the size of the insulating fabric. Then, the air outlet structure 5 of one insulating fabric is connected to the air inlet structure 4 of another connected insulating fabric, connecting the inflation chambers 12 inside multiple insulating fabrics. During inflation, an air pump is connected to the air inlet structure 4 of one insulating fabric, while the air outlet structure 5 of the other insulating fabric is blocked by a sealing structure 8. The air pump is started, and gas enters through the air inlet structure 4. Because the insulating fabrics are interconnected, the inflation of multiple connected insulating fabrics can be completed. After inflation, the air inlet structure 4 is blocked by the sealing structure 8. Due to the arrangement of the first connecting structure 2 and the second connecting structure 3, splicing between multiple insulating fabrics can be achieved, and the arrangement of the air inlet structure 4 and the air outlet structure 5 enables the connection of the inflation chambers 12 in multiple insulating fabrics. When a single sheet of insulation fabric is used alone, the air outlet structure 5 is sealed using the sealing structure 8. After the air pump is connected to the air inlet structure 4, it inflates the air cavity. After inflation, the air inlet structure 4 is sealed again using the sealing structure 8. When multiple sheets of insulation fabric are spliced ​​together, the air inlet structures 4 of the middle sheets are connected to the air outlet structures 5 of the adjacent sheets. For the sheets on the sides, the air inlet structure 4 of one sheet is connected to the air pump for inflation, while the air outlet structure 5 of the other sheet is sealed using the sealing structure 8. After inflation, the air inlet structure 4 connected to the inflation pump is also sealed using the sealing structure 8. In this embodiment, multiple sheets of insulation fabric can be spliced ​​together according to their size. Furthermore, due to the use of the inflation cavity 12 structure, the compressed volume of the insulation fabric is smaller. After use, the spliced ​​sheets of insulation fabric can be divided into several units, making them easy to store.

[0022] It should be noted that the air layer 11 can generally use at least two layers of airtight fabric to avoid air leakage in the air chamber 12, ensuring the airtightness of the air chamber 12 and thus improving its insulation effect. The first connecting structure 2 and the second connecting structure 3 are respectively one of a zipper structure, a Velcro structure, and a snap fastener structure that can be connected. The air inlet structure 4 and the air outlet structure 5 are respectively a plug and a socket that can be connected. When the plug of one insulating fabric is connected to the socket of another insulating fabric, the air chamber 12 of the two adjacent insulating fabrics can be connected; and the connection between the plug and the socket can also ensure the airtightness of the connection between the two. It should also be noted that the air inlet structure 4 can be an insert, and the air outlet structure 5 is a socket. When multiple insulation fabrics are spliced ​​together, the air inlet structure 4 of one of the insulation fabrics on one side is connected to the air inlet nozzle of the air pump, and the air outlet structure 5 of the insulation fabric on the other side should be connected with a plugging structure 8 to prevent gas leakage from the air outlet structure 5. The connection between the plugging structure 8 and the air outlet structure 5 should also ensure airtightness. The first connecting structure 2 and the second connecting structure 3 can be connected to the inflatable layer 11 through the first connecting fabric. Specifically, the first connecting fabric can be connected to the inflatable layer 11 by adhesive, and the first connecting structure 2 and the second connecting structure 3 can be connected to the first connecting fabric by adhesive or sewing. The first connecting fabric has partial perforations to remove body moisture or for local ventilation. The first connecting structure 2 and the second connecting structure 3 are adapted to each other, meaning that the first connecting structure 2 of one thermal insulation fabric can be detachably connected to the second connecting structure 3 of another adjacent thermal insulation fabric; the air inlet structure 4 and the air outlet structure 5 are adapted to each other, meaning that the air inlet structure 4 of one thermal insulation fabric can be detachably connected to the air outlet structure 5 of another thermal insulation fabric, while maintaining airtightness between the air inlet structure 4 and the air outlet structure 5. In this embodiment, the first direction can be the length direction of the inflatable thermal insulation fabric, and the second direction is the width direction of the inflatable thermal insulation fabric. By connecting two adjacent thermal insulation fabrics in the first direction through the first connecting structure 2 and the second connecting structure 3, the thermal insulation fabric can achieve dimensional expansion in the second direction (width direction). The thermal insulation fabric can be one of TPU composite fabric, aerogel fiber fabric, or graphene coated fabric.

[0023] The first connecting structure 2 and the second connecting structure 3 are respectively one of a zipper structure, a Velcro structure, and a snap fastener structure that can be connected. In this embodiment, multiple sheets of thermal insulation fabric can be freely combined like a "puzzle" using standardized connectors (zippers, Velcro, etc.). Users can reasonably match different sizes of thermal insulation fabric according to the temperature and their personal comfort.

[0024] In addition, the air inlet structure 4 and the air outlet structure 5 are respectively a plug and a socket that can be connected. In this embodiment, the standardized design of the plug and socket, and this quick-connect connection, also ensures the sealing and reliability of the air circuit connection.

[0025] Example 2 This embodiment 2 is similar to embodiment 1, except that at least a first insulation zone 111 and a second insulation zone 112 are formed in the air-filled layer 11, and each of the first insulation zone 111 and the second insulation zone 112 has multiple air-filled cavities 12; under the same projected area, the total volume of the air-filled cavities 12 in the first insulation zone 111 is different from the total volume of the air-filled cavities 12 in the second insulation zone 112. Figure 1 As shown, under the same projected area, the total volume of the air chamber 12 in the first insulation zone 111 is greater than the total volume of the air chamber 12 in the second insulation zone 112.

[0026] It should be noted that the inflatable layer 11 can have several levels of insulation zones. The better the insulation effect of the insulation zone, the larger the total volume of the air chambers 12 in the inflatable layer 11 per unit projected area, and the better the insulation effect. The projection direction under the same projected area refers to the projection onto the plane formed by the first direction and the second direction.

[0027] like Figure 1 , Figure 3 As shown, multiple rows of inflation chambers 12 are arranged along a first direction. Adjacent inflation chambers 12 in the same row are connected by air passages 6. The inflation chambers 12 at the beginning of each row are connected by main pipes 7. One end of the main pipe 7 is connected to the air inlet structure 4, and the other end is connected to the air outlet structure 5. In this embodiment, a "tree-like" or "fishbone-like" airflow path design is adopted (the main pipe 7 serves as the "trunk," and each row of inflation chambers 12 serves as a "branch"). Gas can be quickly and evenly distributed from one air inlet structure 4 to all inflation chambers 12, avoiding the problems of insufficient inflation or uneven pressure at the end caused by a traditional single long air passage 6. Simultaneously, the air outlet structure 5 is connected to the other end of the main pipe 7, ensuring that when the air outlet structure 5 is connected to the air inlet structure 4 of another insulation fabric, gas can flow through the main pipe 7 and the air outlet structure 5 into the inflation chamber 12 of the other insulation fabric, improving inflation efficiency.

[0028] It should also be noted that the main pipe 7 connects each row of air chambers 12 into a whole at the head, which enhances the structural integrity of the entire air layer 11 in the width direction (second direction), reduces the relative displacement or twisting of each row of air chambers 12 that may occur during use, and makes the insulation layer more flat and stable.

[0029] Additionally, some of the adjacent rows of inflatable cavities 12 are located within the second insulation zone 112. Among the adjacent rows of inflatable cavities 12, several cavities 12 furthest from the main duct 7 are located within the second insulation zone 112. In this embodiment, this design achieves physically zoned insulation: specifically, areas requiring core insulation (such as the first insulation zone 111 corresponding to the torso) can be designed with a denser concentration of inflatable cavities 12 or higher air pressure, while the extremities or frequently used areas (the second insulation zone 112) employ different insulation strategies. Including the inflatable cavities 12 furthest from the main duct 7 (i.e., the end of the airflow path) in the second insulation zone 112 cleverly utilizes airflow dynamics; the pressure and degree of expansion in this area may differ slightly during inflation, naturally creating a temperature difference, which is more ergonomic.

[0030] In this embodiment, the air inlet structure 4 and the air outlet structure 5 are arranged along the second direction. The air inlet structure 4 and the air outlet structure 5 are positioned at opposite ends of a direction different from the first direction (the direction of the 12 rows of inflation chambers), forming a through-type gas circulation channel. This not only helps to drive a more thorough exchange of air during inflation (avoiding dead space), but also makes the connection positions of external air pumps and other equipment more logical.

[0031] Example 3 This embodiment 3 is similar to embodiment 1, except that, as Figure 2 As shown, the main fabric 1 also includes an outer layer 14 and an inner layer 13 that cover and connect to the upper and lower sides of the inflatable layer 11, respectively. The first connecting structure 2 and the second connecting structure 3 are respectively connected to the two sides of the outer layer 14 along the first direction. In this embodiment, the outer layer 14 and the inner layer 13 can provide a certain degree of protection for the inflatable layer 11, preventing air leakage caused by wear and tear that could lead to airtightness issues in the inflation chamber 12 of the inflatable layer 11.

[0032] The inner layer 13 is made of heat-reflective fabric, and the outer layer 14 is made of abrasion-resistant and scratch-resistant material or a brightly colored material. Reflective markings are provided on the outer layer 14. In this embodiment, the inner layer 13 is made of heat-reflective fabric, which enhances the insulation effect of the insulating fabric. The abrasion-resistant material structure of the outer layer 14 protects the air-filled layer 11 in the middle layer. The brightly colored material structure of the outer layer 14 provides a highly visible and alert visual effect. The reflective markings on the outer layer 14 facilitate quick identification by users when using the product outdoors, especially in dark environments, thus improving safety.

[0033] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0034] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
