[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Because this invention places the heating element inside the cavity of the air bag body, the air bag body of this invention has no visible heating element on its exterior. This eliminates the need for additional decorative fabric or covers to cover the heating element, resulting in a simpler and more aesthetically pleasing overall appearance. It also reduces the user's discomfort and makes the outer surface of the air bag body easier to wash and clean. Furthermore, the heating element of this invention adheres to or touches the inner surface of the cavity, at least when the air bag body is inflated. This allows the heating element to quickly conduct heat to the air bag body, enabling rapid hot compress massage to the areas requiring massage.

[0019] 2. The heating element is fixed to the inner surface of the air bag body by bonding or hot pressing, which makes the fixing method of the heating element relatively simple, and the heating element is stable inside the air bag body, which can quickly conduct heat.

[0020] 3. The insulating outer sheath of the conductive wire is heat-pressed to the air bag body, or the air bag body is sealed with a pipe at the position corresponding to the conductive wire, and the conductive wire is sealed through the pipe, making the connection between the conductive wire and the air bag body simpler and more reliable.

[0021] 4. The edge region design separates the heating element from the airbag body along the extension direction of the support sheet, thereby preventing the heating element from contacting the airbag body in that direction. This prevents the airbag body from softening, deforming, or even bursting due to direct contact with the high temperature generated by the heating element. Furthermore, the separation between the heating element and the airbag body by the support sheet or at least one layer of the support sheet not only facilitates the uniform distribution of heat generated by the heating element but also prevents the heating element from contacting the airbag body, thus preventing the airbag body from softening, deforming, or even bursting due to direct contact with the high temperature generated by the heating element.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments; however, the heating air bag and massage device of the present invention are not limited to the embodiments. Attached Figure Description

[0050] Example 1

[0051] Please see Figure 1-5As shown, this utility model discloses a heated air bag, comprising an air bag body 1 and a heating element 2. The air bag body 1 forms a cavity for containing gas. The heating element 2 is disposed within the cavity of the air bag body 1 and has a conductive wire 23. The conductive wire 23 is sealed to the air bag body 1, with one end of the conductive wire 23 located outside the air bag body 1 for electrical connection to an external power supply device. The heating element 2 is attached to or touches the inner surface of the cavity of the air bag body 1 at least when the air bag body 1 is inflated. Preferably, the part of the heating element 2 that is attached to or touches the air bag body 1 is the part of the air bag body 1 that is in contact with the user's massage area. This facilitates the rapid conduction of heat generated by the heating element 2 to the user's massage area, thereby achieving rapid heat therapy massage.

[0052] In a preferred embodiment, the heating element 2 is bonded or heat-pressed onto the inner surface of the air bag body 1, but the connection method between the heating element 2 and the air bag body 1 is not limited to this. Specifically, in this embodiment, the heating element 2 is bonded and fixed to the inner surface of the air bag body 1 using a film 3 and / or adhesive, such as double-sided adhesive or hot melt adhesive. In other embodiments, the heating element 2 is heat-pressed onto the inner surface of the air bag body 1.

[0053] The heating element 2 includes a support plate 21 and a heating element, preferably a heating wire 22, but is not limited to this. In other embodiments, the heating element is a heating plate. The heating wire 22 is arranged on the support plate 21 in a preset shape and is electrically connected to a conductive wire 23. The preset shape includes one or a combination of straight, S-shaped, wavy, and spiral shapes. The support plate 21 is made of a flexible, heat-resistant material, preferably a fabric material, and can be an elastic or non-elastic fabric. The heating wire 22 is sewn onto the support plate 21. In other embodiments, the heating element 2 includes one of a PI heating film, a PET heating film, or a polyimide heating element. As a preferred embodiment, the heating element 2 is equipped with a temperature sensor that can collect the heating temperature of the heating element 2 in real time and transmit the real-time temperature information to a controller for controlling the working state of the heating element 2, so that the heating temperature of the heating element 2 is within a temperature range suitable for comfortable human massage.

[0054] In this embodiment, a tube 4 is sealed and connected at the position corresponding to the conductive wire 23 of the air bag body 1. The tube 4 is a two-way type, and the conductive wire 23 is sealed and passed through the tube 4. Specifically, the tube 4 is made of a high-frequency hot-pressing material (i.e., TPU or PVC, etc.). Preferably, the tube 4 and the air bag body 1 are made of the same material, and the tube 4 and the air bag body 1 are fixed by hot pressing. The conductive wire 23 and the tube 4 can be sealed by applying adhesive or by using a sealing ring, but are not limited to these methods.

[0055] The airbag body 1 includes one or more pouches, which are heat-sealed to form the inner cavity of the airbag body 1. The tube 4 is then heat-sealed between the heat-sealed edges of the pouches. In this embodiment, there are two pouches, but this is not a limitation. In other embodiments, there is one pouch, which is folded in half and heat-sealed to form the inner cavity of the airbag body 1; in other embodiments, there are more than two pouches. For easy distinction, the two pouches are named the first pouch 11 and the second pouch 12, respectively. The four edges of the first pouch 11 are heat-sealed to the four edges of the second pouch 12, thereby forming the cavity of the airbag body 1. The outer surface of the first pouch 11 is for contact with the user; therefore, the heating element 2 is connected to the inner surface of the first pouch 11. The airbag body 1 is sealed with an air nozzle 5 for inflation and deflation, which is specifically located on the second pouch 12. The entire airbag body 1 is roughly trapezoidal in its uninflated state, but it is not limited to this; the airbag body 1 can also adopt any other suitable shape, such as... Figures 19-22 As shown. In this embodiment, the air bag body 1 has one cavity, but it is not limited to this. In other embodiments, the air bag body 1 is formed by heat-sealing several bag pieces to form multiple cavities. Each cavity is provided with a heating element and an air nozzle 5, as shown. Figure 21 , Figure 22 As shown.

[0056] This utility model discloses a heated air bag, in which the heating element 2 is disposed within the cavity of the air bag body 1. This eliminates the need for an external cover or decorative fabric to conceal the heating element 2, resulting in a simpler and more aesthetically pleasing appearance. It also reduces the user's discomfort and facilitates easy washing and cleaning of the outer surface of the air bag body 1. When the air bag body 1 is inflated, the heating element 2 remains attached to the inner surface of the area of ​​the air bag body 1 that comes into contact with the user. This allows the heating element 2 to quickly transfer heat to the area requiring massage, providing rapid heat therapy and massage.

[0057] Example 2

[0058] Please see Figure 6-Figure 8-2 As shown, the heating air bag of this utility model differs from the first embodiment described above in that: the tube 4 passes through the through hole 121 of the bag sheet, and the outer circumferential surface of the tube 4 is provided with a ring plate 41, which is fixed to the inner or outer surface of the bag sheet by heat pressing. In this embodiment, the through hole 121 is specifically located in the second bag sheet 12, and the ring plate 42 is fixed to the inner surface of the second bag sheet 12 by heat pressing. Therefore, both the tube 4 and the air nozzle 5 extend from the second bag sheet 12.

[0059] Example 3

[0060] Please see Figure 9 , Figure 10As shown, the heating air bag of this utility model differs from the first embodiment described above in that the tube 4 is an elongated oval tube. This tube 4 is also heat-pressed and fixed between the heat-pressed sealing edges of the first bag sheet 11 and the second bag sheet 12.

[0061] Example 4

[0062] Please see Figure 11 , Figure 12 As shown, the heating air bag of this utility model differs from the above embodiment in that: the conductive wire 23 has an insulating outer sheath 231, which is heat-pressed and fixed to the air bag body 1 to achieve a sealed connection between the conductive wire 23 and the air bag body 1. Specifically, the insulating outer sheath 231 of the conductive wire 23 and the air bag body 1 are made of the same material, and the insulating outer sheath 231 is heat-pressed and fixed between the edges of the first bag piece 11 and the second bag piece 12.

[0063] Example 5

[0064] Please see Figure 13 , Figure 14 As shown, the heating air bag of this utility model differs from the above embodiment one or embodiment three in that: multiple tubes 4 are provided, and the multiple tubes 4 are distributed in parallel. The conductive wire 23 is sealed and passed through one of the tubes 4, and the remaining tubes 4 serve as the air passages for inflation and / or deflation of the air bag body 1.

[0065] In this embodiment, there are two tubes 4. One tube 4 is used to pass through the conductive wire 23, and the other tube 4 serves as the air passage for the air bag body 1 to inflate and deflate. The two tubes 4 are respectively heat-pressed and fixed between the edges of the first bag piece 11 and the second bag piece 12.

[0066] Example 6

[0067] Please see Figures 15-18 As shown, the heating air bag of this utility model differs from the above-mentioned embodiments one, three, and four in that: the pipe fitting 4 has a first port 42, a second port 43, and a third port 44 that are interconnected. Therefore, the pipe fitting 4 is a three-way pipe, and the pipe fitting 4 is heat-pressed and fixed between the edges of the first bag piece 11 and the second bag piece 12. The first port 42 is located inside the cavity of the air bag body 1, and the second ports 43 are located outside the cavity of the air bag body 1, respectively. The conductive wire 23 passes through the first port 42 and the second port 43 in sequence and is sealed to the second port 43. The third port 44 constitutes the air inlet and outlet of the air bag body 1. Thus, this utility model does not require a separate air nozzle 5 for the air bag body 1.

[0068] Example 7

[0069] Please see Figure 23As shown, the heating air bag of this utility model differs from the above embodiments in that:

[0070] The support plate 21 includes a heating area 211 and an edge area 212. The heating area 211 is the area of ​​the support plate 21 used to connect the heating element. The edge area 212 is located around the heating area 211, and the width of the edge area 211 is greater than or less than 1 mm and less than or equal to 50 mm. The heating element (i.e., the heating wire 22) is disposed within the heating area 211. At least the edge area of ​​the support plate is attached to the inner surface of the air bag body 1, which is the inner surface of the cavity. In this way, the heating element can be prevented from contacting the air bag body 1 in the extension direction of the support plate 21, thereby preventing the air bag body 1 from softening, deforming, or even bursting due to direct contact with the high temperature generated by the heating element. As a preferred embodiment, the entire surface of the support plate 21 is attached to the inner surface of the air bag body 1.

[0071] In a preferred embodiment, one side of the support sheet 21 is used to adhere to or contact the inner surface of the air bag body 1, and the other side of the support sheet 21 is provided with a heating element (i.e., heating wire 22). The support sheet 21 is a single-layer structure or is composed of multiple layers of sheets stacked together. Specifically, in this embodiment, one side of the support sheet 21 is adhered to the inner surface of the first bag sheet 11 by an adhesive film 3, and the heating wire 22 is located on the other side of the support sheet 21. In this way, the heat generated by the heating wire 22 is first transferred to the support sheet 21 and then to the air bag body 1. This method not only helps to evenly distribute the heat generated by the heating element, but also avoids the heating element from contacting the air bag body 1 in the thickness direction of the support sheet 21, thereby preventing the air bag body 1 from softening, deforming, or even bursting due to direct contact with the high temperature generated by the heating element. This method of avoiding direct contact between the heating element and the air bag body 1 also allows for a more diverse selection of materials for the air bag body 1, rather than being limited to heat-resistant materials.

[0072] Example 8

[0073] Please see Figure 24 As shown, the heating air bag of this utility model differs from the above-described embodiment seven in that:

[0074] The support plate 21 is composed of multiple layers of plates 213 stacked together, and the heating element (i.e., heating wire 22) is disposed between two adjacent layers of plates 213 of the support plate 21.

[0075] In this embodiment, the support sheet 21 is exemplified by being composed of two overlapping sheet layers 213, with the heating wire 22 positioned between these two layers. Specifically, the heating wire 22 can be first fixed to one of the sheet layers, and then the other sheet layer can be fixed to the other sheet layer by bonding or sewing, covering the heating wire 22. Afterward, the exposed side of any sheet layer 213 is attached to the inner surface of the first bag sheet 11 or the second bag sheet 12 using film 3 and / or glue. The multi-layered arrangement of the heating wire 22 in the support sheet 21 also prevents the heating wire 22 from contacting the air bag body 1 in the thickness direction of the support sheet 21, thereby preventing the air bag body 1 from directly contacting the high temperature generated by the heating element and causing softening, deformation, or even bursting.

[0076] The present invention provides a massage device, including an inflation / deflation control mechanism and a heating air bag as described above. The inflation / deflation control mechanism controls the inflation / deflation of the air bag body 1.

[0077] For details on the structure and working principle of the heated air bag and massage device, please refer to the previous description section; they will not be repeated here.

[0078] The present invention relates to a heated air bag and a massage device. The parts not described herein are the same as or can be implemented using existing technologies.

[0079] The above embodiments are only used to further illustrate a heated air bag and massage device of the present invention. However, the present invention is not limited to the embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the technical solution of the present invention.
