Description

Technical Field

[0001] The embodiments of the utility model relate to the technical field of massage devices, and in particular to an air bag, a pneumatic massage system and massage equipment. Background Art

[0002] In pneumatic massage equipment, such as massage chairs, a massage head is arranged on the top of the massage air bag of the pneumatic massage system, and the contact area between the massage head and the human body is smaller than the contact area between the massage air bag and the human body. When the massage air bag is inflated, the massage head bulges to simulate human fingers, forming a squeezing massage. Compared with simply achieving massage by inflating the massage air bag, the massage effect can be improved.

[0003] However, the massage head is directly arranged on the top surface of the massage airbag, which not only forms a bulge when the airbag is inflated, but also remains relatively bulged above the top surface of the massage airbag after the airbag is deflated and contracts. As a result, when the pneumatic massage function is not turned on, the massage head still squeezes the occupant's back, causing a foreign body sensation and discomfort, reducing the sitting experience.

The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by technicians in the technical field of the present invention. The terms used in this specification are only for the purpose of describing specific embodiments and are not used to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0031] The air bag of the embodiment of the utility model is provided with a pleated portion between the air bag main body and the massage head. When the air cavity is deflated and the air bag main body contracts, the pleated portion folds back and concave toward the air cavity to form a groove. The massage head is received in the groove, and at least a part of the massage head is lower than the outer surface of the air bag main body, that is, the massage head can be kept flush or substantially flush with the outer surface of the air bag main body, thereby reducing the foreign body sensation and discomfort caused by the massage head when the air bag does not need massage.

[0032] In order to facilitate understanding of the inventive concept of the utility model, the specific structure of the air bag is described below:

[0033] See also Figure 1-5 The air bag 1000 includes an air bag body 100, a pleated part 200 and a massage head 300. The air bag body 100 is provided with an air cavity 100a; the outer periphery of the pleated part 200 is fixed to the air bag body 100; the periphery of the massage head 300 is fixed to the inner periphery of the pleated part 200; wherein, when the air cavity 100a is deflated and the air bag body 100 contracts, the pleated part 200 is folded back and concave toward the air cavity 100a to form a groove 200a, and the massage head 300 is received in the groove 200a, and the massage head 300 is moved to the inner periphery of the pleated part 200. A small part is lower than the outer surface of the airbag body 100, that is, the massage head 300 can be kept flush or substantially flush with the outer surface of the airbag body 100, thereby reducing the foreign body sensation and discomfort caused by the massage head 300 when the airbag 1000 does not need massage; when the air cavity 100a is inflated and the airbag body 100 expands, the pleated part 200 stretches and expands, forcing the massage head 300 to protrude outward from the pleated part 200, so that the massage head 300 protrudes from the top surface of the airbag body 100 and simulates a human finger to form a squeeze massage. In this way, the airbag 1000 can reduce the foreign body sensation and discomfort caused by the massage head 300 when massage is not needed, thereby improving the user's experience.

[0034] Among them, when the air cavity 100a is deflated, the air bag body 100 shrinks, and the massage head 300 is stored in the groove 200a, the massage head 300 can be completely stored in the groove 200a formed by the pleated portion 200, or partially stored in the groove 200a formed by the pleated portion 200. For example, when the air bag 1000 is used in a massage seat, the seat cushion (such as sponge) covers the air bag 1000; when the massage head 300 is completely stored in the groove 200a, that is, the top of the massage head 300 is flush with the top of the air bag 1000, and there is almost no foreign body sensation; and when the massage head 300 is partially stored in the groove 200a formed by the pleated portion 200, the part of the massage head 300 exposed outside the groove 200a can be buffered and absorbed by the cushion, so that the seated person cannot obviously feel the foreign body sensation generated by the massage head 300, and the corresponding effect can also be achieved.

[0035] For the above-mentioned airbag main body 100, the airbag main body 100 can be provided with an opening (not shown in the figure), and the opening is connected to the air cavity 100a. The outer peripheral edge of the pleated portion 200 is fixed to the peripheral wall of the opening, and the pleated portion 200 and the massage head 300 close the opening. In this way, the pleated portion 200 and the massage head 300 can jointly serve as the inner wall of the air cavity 100a to reduce the material required for the airbag main body 100, thereby reducing the weight of the airbag 1000.

[0036] Specifically, the pleated portion 200 may be an integrally formed structure on the airbag main body 100, which is formed on the airbag main body 100 by molding during the molding process of the airbag main body 100. Alternatively, the pleated portion 200 may be welded to the airbag main body 100 and fixedly connected to the airbag main body 100.

[0037] Furthermore, the airbag body 100, the pleated part 200 and the massage head 300 are integrally formed; or, the airbag body 100 and the pleated part 200 are integrally formed, and the massage head 300 is welded to the pleated part 200 by high-frequency welding; or, the pleated part 200 can be welded to the airbag body 100, and the massage head 300 is welded to the pleated part 200. In this way, the production cost of the airbag 1000 can be reduced, the production cycle can be reduced, and the airbag 1000 has a higher structural strength. Among them, high-frequency welding is a process that uses a high-frequency electromagnetic field to make the molecules inside the material collide violently with each other to generate high temperature, thereby achieving the purpose of welding and welding.

[0038] In some embodiments, the airbag main body 100 also includes a plurality of sub-airbags 11, which are stacked in sequence, and the sub-air cavities 100a of the sub-airbags 11 are connected to form an air cavity 100a, each sub-airbag 11 has two pieces of film material facing each other up and down and are formed by welding, and adjacent sub-airbags 11 are connected specifically by through holes opened on adjacent film materials, so that the airbag main body 100 has a higher height after being inflated; wherein, the airbag main body 100 is integrally formed, or high-frequency welding can be used to reduce the production cost of the airbag main body 100 and reduce the production cycle, and make the airbag main body 100 have higher structural strength. Furthermore, the outer periphery of the pleated portion 200 is fixed to the uppermost sub-air bag 11 along the direction in which the sub-air bags 11 are stacked. Thus, when the air bag 1000 is inflated, the sub-air bags 11 can force the massage head 300 to squeeze the user along the direction in which the sub-air bags 11 are stacked. When the air bag 1000 is deflated and shrinks, the pleated portion 200 folds back and concavely faces the sub-air chambers 100a of the sub-air bags 11 to form a groove 200a. The massage head 300 is received in the groove 200a. The massage head 300 can remain flush or substantially flush with the outer surface of the uppermost sub-air bag 11. Furthermore, after the sub-air bags 11 are inflated, they are convex along the direction in which the sub-air bags 11 are stacked, so that the air bag 1000 has a better squeezing effect along the direction in which the sub-air bags 11 are stacked. Among them, the uppermost sub-air bag 11 is integrally formed with the pleated portion 200 or high-frequency welded.

[0039] For the above-mentioned folded portion 200, please refer to Figure 6 The pleated portion 200 has at least one pleated ring 21. When the airbag main body 100 shrinks, along the direction from the outer periphery of the pleated portion 200 to the inner periphery, at least one pleated ring 21 is stepped, so that the surface of the pleated portion 200 after folding back is relatively flat, thereby reducing the foreign body feeling and discomfort of the pleated portion 200. The pleated portion 200 has at least one pleated ring 21, and the pleated ring 21 can be a circular ring; when there are multiple pleated rings 21, the heights of the pleated rings 21 can be equal or unequal; and the shape of the pleated ring 21 along the deflation shrinkage direction can be U-shaped or V-shaped. Furthermore, along the direction from the outer periphery to the inner periphery of the pleated portion 200, at least one pleated ring 21 is arranged in sequence from large to small in diameter, so that when the pleated portion 200 is folded back, the outer pleated ring 21 is folded outward and surrounded by the outer periphery of the inner pleated ring 21, and when the pleated portion 200 is folded back, the pleated portion 200 forms a radial supporting structure with the massage head 300 as the center; further, after the pleated portion 200 is folded back, the inner diameter changes of adjacent pleated rings 21 are almost equal, so that the intervals between adjacent pleated rings 21 remain almost unchanged before and after the pleated portion 200 is folded back, thereby reducing the difference in feeling brought to the user by the pleated portion 200 before and after massage.

[0040] In a preferred embodiment, the pleated portion 200 is fixed to the top of the uppermost sub-air bag 11. When the air bag main body 100 shrinks and the pleated portion 200 folds back, the outer surface of at least one pleated ring 21 is flush with the top of the uppermost sub-air bag 11, so that the pleated portion 200 after shrinkage is relatively flat, thereby reducing the foreign body sensation of the pleated portion 200. Further, there is a certain distance between the outer periphery of the pleated portion 200 and the periphery of the uppermost sub-air bag 11, that is, the pleated portion 200 and the massage head 300 do not completely cover the top of the uppermost sub-air bag 11. In this way, after the air bag 1000 is deflated and shrunk, the top of the uppermost sub-air bag 11 has a certain flat surface to ensure a certain degree of comfort. In addition, the material of the pleated portion 200 can be selected to be the same as that of the uppermost sub-air bag 11, so that the pleated portion 200 and the uppermost sub-air bag 11 can be connected together.

[0041] For the above-mentioned massage head 300, the massage head 300 can be a solid body, specifically a solid body of the same material as the air bag main body 100, such as a TPU (thermoplastic polyurethane) solid body, or a solid body of a different material from the air bag main body 100, such as a metal solid body, so that the massage head 300 has a better hardness, thereby meeting the massage requirements; and when the massage head 300 is a solid body of the same material as the air bag main body 100, the massage head 300 can be welded on the fold part 200 or integrally formed with the fold part 200. Alternatively, the massage head 300 is concave from the air cavity 100a to the outside to form a receiving cavity 300a, so that the thickness of the massage head 300 becomes thinner, and then the hardness of the massage head 300 becomes smaller. Among them, the receiving cavity 300a and the air cavity 100a can be connected or isolated. It can be understood that the receiving cavity 300a of different volumes can be set according to the needs to obtain massage heads 300 with different hardness.

[0042] Furthermore, there may be a filler (not shown) in the receiving cavity 300a, so that the hardness of the massage head 300 can be adjusted by adjusting the hardness of the filler. It is understandable that the material of the filler can be adjusted according to the needs, for example, the filler can be gas, liquid or solid, wherein the filled solid can include elastic material (soft glue), flexible material (sponge, etc.) or porous material, etc. Among them, when the receiving cavity 300a and the air cavity 100a are connected to each other, the filler in the receiving cavity 300a is preferably solid or gas filled into the air cavity 100a; for the solid filler, a diaphragm with a through hole can be set at the connection between the receiving cavity 300a and the air cavity 100a, so that the solid filler can be carried and set in the receiving cavity 300a. Obviously, the setting method of the solid filler is not limited to this, and it can also be filled and fixed by feasible methods such as gluing.

[0043] Furthermore, the massage head 300 and the folded portion 200 can be integrally formed, or the massage head 300 and the folded portion 200 can be welded, and the welding method is preferably high-frequency welding. In addition, the material of the massage head 300 can be selected to be the same as that of the folded portion 200, so as to facilitate the connection between the massage head 300 and the folded portion 200.

[0044] In a preferred embodiment, the massage head 300 is located at the most convex part of the top of the uppermost sub-air bag 11, so that after the air bag 1000 is inflated, the massage head 300 can be better protruded from the top of the uppermost sub-air bag 11, thereby obtaining a better squeezing effect. Further, the most convex part of the top of the uppermost sub-air bag 11 is located at the center of the top, so that the top of the uppermost sub-air bag 11 is centered on the massage head 300, and the squeezing force of the top of the uppermost sub-air bag 11 can be evenly gathered at the periphery of the massage head 300, so that the massage head 300 outputs a more concentrated squeezing force.

[0045] In some embodiments, the air bag 1000 also includes an air nozzle 400. The setting position of the air nozzle 400 is not limited, and can be on any sub-air bag 11, such as the top-layer sub-air bag 11, the middle-layer sub-air bag 11 or the bottom-layer sub-air bag 11, preferably the bottom-layer sub-air bag 11, wherein the bottom-layer sub-air bag 11 refers to the sub-air bag 11 located at the bottom along the stacking direction of several sub-air bags 11, and the air nozzle 400 is connected to the air cavity 100a, and the air nozzle 400 is used to connect to an external gas source or gas distribution device.

[0046] In the embodiment of the utility model, the air bag 1000 includes an air bag main body 100, a pleated part 200 and a massage head 300. The air bag main body 100 is provided with an air cavity 100a; the outer periphery of the pleated part 200 is fixed to the air bag main body 100; the periphery of the massage head 300 is fixed to the inner periphery of the pleated part 200; wherein, when the air cavity 100a is deflated and the air bag main body 100 shrinks, the pleated part 200 is folded back and concave toward the air cavity 100a to form a groove 200a, and the massage head 300 is The massage head 300 is stored in the groove 200a, and at least part of it is lower than the outer surface of the airbag body 100, that is, the massage head 300 can be kept flush or substantially flush with the outer surface of the airbag body 100, thereby reducing the foreign body sensation and discomfort caused by the massage head 300 when the airbag 1000 does not need massage; when the air cavity 100a is inflated and the airbag body 100 expands, the pleated part 200 stretches and unfolds, forcing the massage head 300 to bulge outward to simulate a squeeze massage by a human finger. In this way, the airbag 1000 can reduce the foreign body sensation and discomfort caused by the massage head 300 when massage is not needed, thereby improving the user's experience, while meeting the massage needs.
