Description

Technical Field

[0001] This utility model relates to the technical field of massager assembly, and more specifically, to an air bag device capable of adjusting the massage intensity. Background Technology

[0002] With the popularization of massage equipment, traditional airbag massage devices mostly adjust the massage intensity by changing the inflation pressure or airbag volume, but they have the following technical defects: due to structural limitations, airbag massage cannot be combined with various mechanical massage heads like mechanical massage, resulting in a simple airbag massage structure, weak massage intensity, and poor massage effect.

[0003] Existing patents, such as CN219110120U, involve setting a massage head on the top of the bottom airbag. The massage head is surrounded by an airbag membrane to form a cavity to fill the cavity. During massage, the massage head has a higher hardness and a smaller area than the top surface of the bottom airbag, resulting in a higher massage intensity on the body and improving the massage effect. However, its massage intensity cannot achieve local pressure gradient control, making it difficult to meet the differentiated massage needs of different body parts (such as acupoints and muscle groups).

[0004] Therefore, there is an urgent need for an airbag device that can adjust the massage intensity. Utility Model Content

[0005] In view of this, in order to solve the above problems, this utility model proposes an airbag device capable of adjusting massage intensity, including multiple bottom airbags 10 and an external air source connected to them. Each bottom airbag 10 is provided with an airbag membrane 30 at its top. Each airbag membrane 30 has a massage head 40 protruding from the middle of its center towards the distal end of the top of the bottom airbag 10. The massage head 40 has a hollow structure and is filled with a filling material 41. The hollow massage head 40 and the airbag membrane 30 move up and down in linkage when the bottom airbags 10 are inflated. The outer surfaces of the multiple massage heads 40 are divided into three structures, including the outer surface of the massage head 40 having outward first protrusions 42, the outer surface of the massage head 40 having inward second protrusions 43, and the outer surface of the massage head 40. The surface is smooth. The corresponding massage head 40 is selected and massaged by the massage head 40 and the air bladder membrane 30 rising in conjunction with the bottom air bladder 10 when inflated. The outer surface of the unselected massage head 40 is lowered in conjunction with the massage head 40 and the air bladder membrane 30 when inflated to avoid the corresponding area. For example, when the first protrusion 42 contacts the human body, the height of the massage head 40 and the solid structure work together to increase the local pressure, which is suitable for deep muscle stimulation. The concave arc design of the second protrusion 43 increases the contact area. Combined with the thin-walled area formed by the mold, the massage head 40 collapses elastically when pressed, reducing the peak pressure, which is suitable for sensitive area care. This meets the differentiated massage needs of different body parts (such as acupoints and muscle groups).

[0006] An airbag device capable of adjusting massage intensity includes multiple bottom airbags 10 and an external air source connected thereto. Each bottom airbag 10 has an airbag membrane 30 at its top, and each airbag membrane 30 has a massage head 40 protruding from the middle of its center towards the distal end of the top of the bottom airbag 10. The massage head 40 has a hollow structure and contains a filling material 41 inside the hollow structure. The massage head 40 and the airbag membrane 30 move up and down in conjunction with each other when their corresponding bottom airbags 10 are inflated. The device is characterized in that the outer surfaces of the multiple massage heads 40 have three structures: the outer surface of the massage head 40 has outward first protrusions 42, the outer surface of the massage head 40 has inward second protrusions 43, and the outer surface of the massage head 40 is smooth. The outward first protrusions 42 are used to increase the massage intensity, the inward second protrusions 43 are used to reduce the massage intensity, and the smooth surface is used to maintain the existing massage intensity. Different massage intensity levels can be achieved by selecting different surface structures of the massage heads 40.

[0007] Furthermore, the outward first protrusion 42 is a solid structure.

[0008] Furthermore, the outwardly protruding first protrusion 42 is integrally formed or welded to the massage head 40.

[0009] Furthermore, the inwardly protruding second convex point 43 is an inwardly concave arc-shaped structure.

[0010] Furthermore, the inwardly protruding second protrusion 43 is formed by pressing the surface of the massage head 40 with a mold, thereby increasing the softness of the massage head 40.

[0011] In some embodiments, the filler 41 is a cross-shaped rib that is connected to the inner wall of the massage head 40 to enhance the massage intensity of the massage head 40.

[0012] Furthermore, the rib, airbag membrane 30, bottom airbag 10, massage head 40, outward first protrusion 42 and inward second protrusion 43 are all made of thermoplastic polyurethane.

[0013] In some embodiments, a welding ring 44 is provided around the outer periphery of the massage head 40. The welding ring 44 is located on the airbag diaphragm 30, and the welding ring 44 fixes the airbag diaphragm 30 to the top of the bottom airbag 10 by high-frequency welding.

[0014] Furthermore, the airbag membrane 30 between the welding ring 44 and the massage head 40 is provided with a hollow area or a wavy lace structure 45 for weight reduction.

[0015] In some embodiments, the bottom airbag 10 is composed of at least two layers of TPU film laminated and bonded together, and is connected to the air supply device through an air tube 20.

The airbag device includes multiple bottom airbags 10 and an external air source connected to them. Each bottom airbag 10 has an airbag membrane 30 at its top. Each airbag membrane 30 has a massage head 40 protruding from the center of its middle portion towards the distal end of the top of the bottom airbag 10. The massage head 40 has a hollow structure and contains a filling material 41. The hollow massage head 40 and the airbag membrane 30 move in tandem when the bottom airbags 10 are inflated. The outer surfaces of the multiple massage heads 40 have three structures: outward-facing first protrusions 42 and inward-facing second protrusions 43 distributed on the outer surface of the massage head 40. The outer surface of the massage head 40 is smooth. The corresponding outer surface structure of the massage head 40 is selected and massaged by the massage head 40 and the air bladder membrane 30 rising in conjunction with the bottom air bladder 10 when inflated.

Each bottom airbag 10 has an airbag membrane 30 at its top, and each airbag membrane 30 has a massage head 40 protruding from the middle of the top of the bottom airbag 10. The massage head 40 has a hollow structure, and a filling material 41 is provided inside the hollow structure. The massage head 40 and the airbag membrane 30 move up and down in conjunction with each other when their corresponding bottom airbags 10 are inflated. The outer surfaces of the multiple massage heads 40 are divided into three structures, including the outer surface of the massage head 40 having outwardly protruding first protrusions 42 distributed on it, and the outer surface of the massage head 40 having... The massage head 40 has an inwardly oriented second protrusion 43 and a smooth outer surface. The outwardly oriented first protrusion 42 is used to increase the massage intensity, and the inwardly oriented second protrusion 43 is used to reduce the massage intensity. The smooth surface is used to maintain the existing massage intensity. Different surface structures of the massage head 40 can be selected to perform different degrees of massage. The outwardly oriented first protrusion 42 is a solid structure and is integrally formed or welded to the massage head 40. The inwardly oriented second protrusion 43 is an inwardly concave arc-shaped structure and is formed by pressing the surface of the massage head 40 with a mold to increase the softness of the massage head 40.

[0027] The filling material 41 is a cross-shaped rib, which is connected to the inner wall of the massage head 40 to enhance the massage intensity of the massage head 40. The rib, airbag membrane 30, bottom airbag 10, massage head 40, outward first protrusion 42 and inward second protrusion 43 are all made of thermoplastic polyurethane.

[0028] A welding ring 44 is provided around the outer periphery of the massage head 40. The welding ring 44 is located on the airbag membrane 30. The welding ring 44 fixes the airbag membrane 30 to the top of the bottom airbag 10 by high-frequency welding. The airbag membrane 30 between the welding ring 44 and the massage head 40 is provided with a hollow area or a wavy lace structure 45 for weight reduction.
