Description

Technical Field

[0001] This application relates to the technical field of massage devices, and in particular to a massage air bag. Background Technology

[0002] The massage equipment industry has achieved remarkable development in recent years. With the improvement of people's living standards and the increasing attention to health and wellness, the market demand for massage equipment has shown a continuous growth trend. As a core component of massage equipment, the performance of massage airbags directly affects the quality of the massage effect and the user experience. The widespread application of massage airbags provides people with a more convenient and comfortable massage method, which can relieve physical fatigue and promote blood circulation to a certain extent, playing a vital role in many fields such as health care and rehabilitation.

[0003] In conventional massage airbags, the inner surfaces of the airbags are in direct contact during inflation, which can produce noticeable noise when the vacuum effect is suddenly released. This noise negatively impacts the user experience and also diminishes the perceived quality of the massage device. Utility Model Content

[0004] In order to minimize abnormal noise during the inflation process, this application provides a massage air bag.

[0005] The massage airbag provided in this application adopts the following technical solution: A massage air bag includes an elastic noise-reducing sheet, and a plurality of first air bags, at least one second air bag, and a third air bag connected in sequence. The first air bags are connected to air tubes, and the two ends of the elastic noise-reducing sheet are respectively disposed inside the second air bag and the third air bag. When there are multiple second air bags, the two ends of the elastic noise-reducing sheet are also respectively disposed inside two adjacent second air bags.

[0006] By adopting the above technical solution and setting elastic noise reduction sheets between specific adjacent air bags, the vacuum effect caused by the direct contact of the inner surfaces of the air bags during deflation is effectively prevented, thereby eliminating the main bursting noises as much as possible.

[0007] Preferably, the elastic noise reduction sheet includes a first noise reduction sheet, a connecting portion, and a second noise reduction sheet connected in sequence. The connecting portion is located between two adjacent air bags, and the first noise reduction sheet and the second noise reduction sheet are respectively disposed in adjacent air bags.

[0008] By adopting the above technical solution, the connecting part is located between the air bags and plays a connecting and positioning role, so that the first noise reduction plate and the second noise reduction plate can be stably suspended in the air bag chamber without moving or drifting at will, thus ensuring the reliability of the noise reduction effect.

[0009] Preferably, the first noise reduction sheet and the second noise reduction sheet are curved, and the first noise reduction sheet and the second noise reduction sheet are attached to the inner wall of the air bag they are in.

[0010] By adopting the above technical solution, the fitting design allows the noise reduction sheet to deform synchronously and naturally with the inner wall of the air bag, avoiding additional mechanical stress and friction caused by shape mismatch.

[0011] Preferably, the first noise reduction sheet, the connecting part, and the second noise reduction sheet are integrally formed.

[0012] By adopting the above technical solution, the possibility of components separating or falling off during long-term use is avoided, ensuring the durability and stability of the noise reduction function.

[0013] Preferably, the corners of the elastic noise reduction sheet are rounded chamfers.

[0014] By adopting the above technical solution, the arc chamfer can greatly reduce or even eliminate the risk of the noise reduction sheet scratching, abrading or puncturing the inner wall of the air bag during the inflation and deflation process, thereby improving the safety and service life of the product.

[0015] Preferably, the elastic noise-reducing sheet is made of TPU material.

[0016] By adopting the above technical solution, TPU material has extremely high wear resistance and repeated bending resistance, adapting to the multiple inflation and deflation cycles of the air bag per minute, thus ensuring the long life of the noise reduction sheet.

[0017] In summary, this application includes at least one of the following beneficial technical effects: 1. By using elastic noise-reducing sheets to prevent direct contact with the inner wall of the air bag, the abnormal noise generated during inflation and deflation is effectively eliminated, and the quietness performance is significantly improved; 2. The elastic noise reduction sheet is made of soft material with rounded edges, which can flexibly deform with the air bag without scratching it, thus ensuring the product's lifespan while achieving noise reduction.

[0020] The following combination Figures 1-4 This application will be described in further detail.

[0021] This application discloses a massage air bag.

[0022] Reference Figure 1 and 2 A massage airbag includes an elastic noise-reducing sheet 4, and a first airbag 1, a second airbag 2, and a third airbag 3 connected in sequence. The two ends of the elastic noise-reducing sheet 4 are respectively disposed within the second airbag 2 and the third airbag 3, and the first airbag 1 is connected to an air tube 7. By providing the elastic noise-reducing sheet 4, direct contact between the inner surfaces of the second airbag 2 and the third airbag 3 can be avoided, thereby reducing abnormal noise caused by the sudden release of air due to the vacuum effect during inflation.

[0023] The first airbag 1 includes two first mounting pieces 11, and the first mounting pieces 11 are generally arc-shaped plates. The two first mounting pieces 11 are arranged facing each other, and their circumferential edges are fixedly connected by welding to form a first chamber 12. The second airbag 2 and the third airbag 3 have similar structures to the first airbag 1. The second airbag 2 includes two second mounting pieces 21 and forms a second chamber 22, and the third airbag 3 includes two third mounting pieces 31 and forms a third chamber 32.

[0024] The first air bag 1 and the second air bag 2 are fixedly connected by welding, and the adjacent first mounting plate 11 and second mounting plate 21 are provided with first connecting holes 5 to connect the first chamber 12 and the second chamber 22. Similarly, the second air bag 2 and the third air bag 3 are fixedly connected by welding, and the adjacent second mounting plate 21 and third mounting plate 31 are provided with second connecting holes 6 to connect the second chamber 22 and the third chamber 32.

[0025] refer to Figure 2 and Figure 3The elastic noise-reducing sheet 4 includes a first noise-reducing sheet 41, a connecting portion 42, and a second noise-reducing sheet 43 connected in sequence. The first noise-reducing sheet 41 is located in the third chamber 32, and the second noise-reducing sheet 43 is located in the second chamber 22. The first noise-reducing sheet 41 and the second noise-reducing sheet 43 are generally triangular plates with a certain curvature, and the side length of the first noise-reducing sheet 41 and the second noise-reducing sheet 43 near the connecting portion 42 is greater than the diameter of the second connecting hole 6. Furthermore, the curvature of the first noise-reducing sheet 41 conforms to the curvature of the third mounting piece 31 near the second air bag 2, and the curvature of the second noise-reducing sheet 43 conforms to the curvature of the second mounting piece 21 near the third air bag 3. The fitted curvature ensures maximum contact area between the first noise-reducing sheet 41 and the second noise-reducing sheet 43 and the inner wall of the airbag, thereby most effectively eliminating any gaps that may generate noise and improving the isolation effect. Furthermore, it allows the inner wall of the airbag to deform synchronously and naturally, avoiding additional mechanical stress and friction caused by shape mismatch, protecting the airbag and extending the lifespan of the elastic noise-reducing sheet 4 itself. The corners of both the first noise-reducing sheet 41 and the second noise-reducing sheet 43 have a rounded chamfered structure, thereby reducing damage to the third mounting plate 31 and the second mounting plate 21.

[0026] The elastic noise-reducing sheet 4 is made entirely of TPU material. TPU material is relatively soft, has good flexibility and wear resistance, and can adapt to the deformation of the air bag during inflation and deflation. The second noise-reducing sheet 43 can be folded and inserted into the second chamber 22, and then the third air bag 3 is connected to the second air bag 2. Preferably, the first noise-reducing sheet 41, the connecting part 42, and the second noise-reducing sheet 43 are integrally molded. The integrally molded structure can ensure the integrity and stability of the elastic noise-reducing sheet 4 and reduce problems caused by loose connections between components.

[0027] refer to Figure 4 In some other embodiments, multiple second air bags 2 may be provided, and the first air bag 1 is connected to the first air bag 1 in sequence through multiple second air bags 2 and third air bags 3. When multiple second air bags 2 are provided, multiple elastic noise reduction sheets 4 are provided, and the two ends of the elastic noise reduction sheets 4 are respectively provided in two adjacent second air bags 2, so as to improve the quietness and comfort of the overall massage component.

[0028] The implementation principle of a massage airbag according to an embodiment of this application is as follows: gas is injected into the first airbag 1 through the air tube 7. The gas flows sequentially into the second airbag 2 through the first connecting hole 5 and into the third airbag 3 through the second connecting hole 6, causing each airbag to expand sequentially. When the airbags are inflated, the two ends of the elastic noise-reducing sheet 4 effectively prevent direct contact or adhesion between the inner walls of the second airbag 2 and the third airbag 3, thereby eliminating the bursting noise caused by the vacuum effect generated by the instantaneous separation of the airbag walls. Furthermore, the elastic noise-reducing sheet 4 is made of a flexible material and can bend with the deformation of the airbag, thus reducing noise without affecting the normal inflation and deflation function of the airbag.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
