[0035] An embodiment of the present application provides an airbag and applies the airbag to a massage device. By utilizing the transformation process of the airbag expanding, tensing, and relaxing during the inflation and deflation processes, the area to be massaged of the user can be repeatedly squeezed and massaged, relaxed, and kneaded, so that the muscles of the area to be massaged of the user can be relaxed.
[0036] Such as Figures 1 to 3As shown in the figure, the airbag provided by the embodiment of the present application includes two airbag structures and a flexible connection part 10. The two airbag structures are the first airbag structure 100 and the second airbag structure 200. The first airbag structure 100 and the second airbag structure 200 are respectively connected to both ends of the flexible connection part 10. When inflated, the ends of the first airbag structure 100 and the second airbag structure 200 away from the flexible connection part 10 approach each other, so as to repeatedly perform squeezing massage on the part of the user to be massaged. Among them, both the first airbag structure 100 and the second airbag structure 200 include a first airbag 30 and a second airbag 20. That is to say, the airbag of the present application has a total of two second airbags 20 and two first airbags 30, and the first airbag 30 and the second airbag 20 are stacked.
[0037] When the user uses the massage device equipped with the above airbag to massage the part to be massaged, when the airbag is inflated, both the first airbag structure 100 and the second airbag structure 200 expand and tighten. Then, the ends of the first airbag structure 100 and the second airbag structure 200 away from the flexible connection part 10 approach each other, so that the first airbag structure 100 and the second airbag structure 200 perform squeezing massage operations on the part to be massaged in a coordinated manner. Since the first airbag structure 100 and the second airbag structure 200 are respectively connected to both ends of the flexible connection part 10, the squeezing massage of the first airbag structure 100 and the second airbag structure 200 on the part to be massaged can be coordinated, so that the massage action on the part to be massaged can be similar to the massage action of manual kneading. Inflating and deflating repeatedly in this way, so as to repeatedly perform squeezing massage and relaxation on the part of the user to be massaged, so that the muscles of the part of the user to be massaged are relaxed, feel comfortable, and improve the massage effect.
[0038] Such as Figure 2 、 Figure 3 and Figure 6As shown, the first airbag 30 and the flexible connection part 10 are formed by the first diaphragm 31 and the second diaphragm 32. In fact, the flexible connection part 10 and the two first airbags 30 are an integral module component formed by hot pressing the first diaphragm 31 and the second diaphragm 32. Not only is the connection stability between the flexible connection part 10 and the first airbag 30 good, but also the hot pressing processing efficiency is high. When hot pressing the first diaphragm 31 and the second diaphragm 32, first stack the first diaphragm 31 and the second diaphragm 32, fixedly connect some edges of the first diaphragm 31 and the second diaphragm 32 to form two edge connection structures 33, and fixedly connect the non-edge parts of the first diaphragm 31 and the second diaphragm 32 to form two spaced first partition parts 34. In this way, an adjacent edge connection structure 33 and a first partition part 34 are connected to form a first airbag 30, and another adjacent edge connection structure 33 and another first partition part 34 are connected to form another first airbag 30. Moreover, a flexible connection part 10 is formed between the two first partition parts 34. Using the first diaphragm 31 and the second diaphragm 32 for hot pressing to integrally form the flexible connection part 10 and the two first airbags 30, compared with connecting the two ends of the flexible connection part 10 to the two first airbags 30 respectively to form a module component, the hot pressing integral forming processing method is simpler and faster, significantly improving the processing efficiency and reducing the time cost of production and processing. And when assembling this module component to the massage device, compared with separately setting two first airbags 30, for the module component integrally formed with the flexible connection part 10 and the two first airbags 30, only need to connect and fix the flexible connection part 10, then the two first airbags 30 can be assembled, with convenient assembly and high assembly efficiency.
[0039] In the airbag provided by the present application, two first airbags 30 are symmetrically connected to both ends of the flexible connection part 10 with respect to the flexible connection part 10, and two second airbags 20 are symmetrically arranged at both ends of the flexible connection part 10 with respect to the flexible connection part 10. When the airbag is inflated, the first airbag 30 pushes against the second airbag 20 so that the second ends of the two second airbags 20 approach each other, thereby squeezing and massaging the part of the user to be massaged. During the inflation process of the second airbag 20 and the first airbag 30, the two inflated first airbags 30 both flip towards the direction close to the flexible connection part 10 with the connection position between them and the flexible connection part 10 as the rotation fulcrum, and the second airbag 20 flips towards the direction close to the flexible connection part 10 with the connection position between it and the first airbag 30 as the fulcrum. When the airbag is inflated and expanded, the first airbag 30 will push against the second airbag 20 to squeeze the part of the user to be massaged, thereby forming a squeezing and massaging effect on the part of the user to be massaged. In this way, during the process of repeated inflation and deflation of the airbag, the second airbag 20 and the first airbag 30 always work stably and coordinately to squeeze and massage the part of the user to be massaged, just like the human hand kneading and massaging the part to be massaged, so that the muscles of the part of the user to be massaged are relaxed, the user feels comfortable, and the massage effect is improved.
[0040] When inflating or deflating, the second airbag 20 and the first airbag 30 can be inflated or deflated simultaneously. Alternatively, the second airbag 20 can be inflated first, and after the second airbag 20 is completely inflated, the first airbag 30 is inflated until the first airbag 30 is completely inflated; then, when performing the deflation operation, the first airbag 30 is deflated first, and after the first airbag 30 is completely deflated, the second airbag 20 is deflated until the second airbag 20 is also completely deflated.
[0041] When the airbag is inflated in the inflation mode of "the second airbag 20 is inflated first and then the first airbag 30 is inflated", the second airbag 20 forms a first-stage squeezing and massaging effect on the part of the user to be massaged when inflated, and the first airbag 30, when inflated, expands and pushes against the second airbag 20 to continue squeezing the part of the user to be massaged, thereby forming a second-stage squeezing and massaging effect on the part of the user to be massaged. In this way, during the process of repeated inflation and deflation of the airbag, the second airbag 20 and the first airbag 30 always work stably and coordinately to squeeze and massage the part of the user to be massaged, just like the human hand kneading and massaging the part to be massaged, so that the muscles of the part of the user to be massaged are relaxed, the user feels comfortable, and the massage effect is improved.
[0042] Such as Figure 1 、 Figure 3 and Figure 4As shown, massage protrusions 23 are provided on the side of the second airbag 20 facing away from the first airbag 30. In this way, when the second airbag 20 is inflated, the second airbag 20 expands and the massage protrusions 23 abut against the part of the user to be massaged. The squeezing force and feeling of the massage protrusions 23 squeezing and massaging the part of the user to be massaged are more significant. That is, the effect of the massage protrusions 23 kneading and massaging the part of the user to be massaged is better, the muscles of the part of the user to be massaged are relaxed, and the user experience is improved.
[0043] As Figure 2 and Figure 6 shown, the airbag further includes a second partition 35 and an air nozzle 40. The first partition 34 is a continuous partition, and the first partition 34 includes a first section 341 and a second section 342. The second section 342 bulges and bends towards the flexible connection part 10. The first partition 34 and the second partition 35 are arranged at intervals, the second partition 35 is located between the two ends of the second section 342, and the second partition 35 is in the same extending direction as the first section 341. Specifically, as Figure 2 shown, the second partition 35 is strip-shaped, Figure 2 as shown, the arrow Y is the length direction of the second partition 35, that is, the second partition 35 extends along the direction Y, and the extending direction of the first section 341 is also the direction Y, Figure 2 as shown, the arrow X is the width direction of the second partition 35. Therefore, "the first partition 34 and the second partition 35 are arranged at intervals" means that: whether in the direction Y or in the direction X, there is an interval between the first partition 34 and the second partition 35. Among them, the air nozzle 40 is arranged in the area enclosed by the second section 342 and the second partition 35.
[0044] When assembling the airbag to the massage device, the airbag needs to be connected to an air pipe and an air pump. Since the airbag fixes the overall working position of the airbag through the flexible connection part 10, when the airbag inflates and expands or contracts, the air nozzle 40 will rise and fall together with the expansion and contraction of the first airbag 30, resulting in the air nozzle and the air pipe being easily loosened. In response to this, the airbag provided in this application is provided with a second partition 35, so that the cavity volume of the area enclosed by the second section 342 and the second partition 35 in the first airbag 30 is much smaller than the cavity volume of other areas in the first airbag 30. The air nozzle 40 is arranged in the area enclosed by the second section 342 and the second partition 35. The expansion and contraction range of the cavity in this area is small, so the position change of the air nozzle 40 and the air pipe rising and falling is small (almost unchanged or the position change can be ignored), which is beneficial to maintaining the stability of the air nozzle 40 and the air pipe. And, the air nozzle 40 is arranged in the area enclosed by the second section 342 and the second partition 35, that is, the air nozzle 40 is arranged close to the flexible connection part 10, so that it is convenient to arrange the air pipe at the flexible connection part 10 and optimize the air pipe laying path.
[0045] As Figure 3 and Figure 5 shown, the airbag further includes a connection structure 22. Among them, as Figure 4 and Figure 5 shown, the second airbag 20 has a first end 24 close to the flexible connection portion 10 and a second end 25 far from the flexible connection portion 10. The first end 24 of the second airbag 20 is connected to the first airbag 30 through the connection structure 22. The connection structure 22 is provided with a vent hole 21. The second airbag 20, the first airbag 30 and the vent hole 21 are communicated with each other. The connection structure 22 is connected within the area enclosed by the second section 342 and the second partition portion 35. In this way, the cavity of the second airbag 20 is communicated with the cavity of the first airbag 30. During inflation, the second airbag 20 and the first airbag 30 are inflated or deflated simultaneously. Since the second airbag 20 and the first airbag 30 are inflated or deflated simultaneously, that is, the second airbag 20 and the first airbag 30 are inflated through a hose, the number of hoses laid is reduced, the difficulty of laying hoses is reduced, and the cost is also reduced. Moreover, the connection structure 22 is far from the second end 25 of the second airbag 20 (the second end 25 of the second airbag 20 is the free end of the second airbag 20). In this way, when the airbag is inflated, the second end 25 of the second airbag 20 is pushed up by the first airbag 30 and turned towards the flexible connection portion 10 better to squeeze and massage the part to be massaged.
[0046] As Figure 3 and Figure 6 shown, the distance from the connection position of the connection structure 22 to the first airbag 30 to the center line 131 of the flexible connection portion 10 is L1, and the distance from the air nozzle 40 to the center line 131 of the flexible connection portion 10 is L2, where L2 < L1. In the first airbag structure 100 and the second airbag structure 200 respectively, this makes the connection position of the connection structure 22 to the first airbag 30 and the connection position of the air nozzle 40 on the first airbag 30 staggered in the direction X. And, the connection position of the connection structure 22 to the first airbag 30 is formed by hot pressing, and the air nozzle 40 is also hot pressed and fixed on the first airbag 30. Therefore, the staggered positions facilitate hot pressing at the two positions simultaneously, improving the processing efficiency. And, the air nozzle 40 is closer to the flexible connection portion 10, so that the air flow can flow more concentratedly to the first airbag 30 and the second airbag 20 during inflation, improving the inflation efficiency.
[0047] As Figure 1 and Figure 2As shown, when neither the first airbag 30 nor the second airbag 20 is inflated, the projection of the second airbag 20 on the plane where the flexible connection part 10 is located at least covers a part of the projection of the first airbag 30 on the plane where the flexible connection part 10 is located. Thus, during the inflation process of the airbag, the second airbag 20 expands and squeezes and massages the part of the user to be massaged. Moreover, when the first airbag 30 expands, since the projection of the second airbag 20 at least covers a part of the projection of the first airbag 30, the part of the first airbag 30 that overlaps with the second airbag 20 in projection will push against the second airbag 20, causing the second airbag 20 to continue squeezing and massaging the part to be massaged. In this way, the second airbag 20 has a distinct sense of hierarchy in repeatedly squeezing and massaging the part of the user to be massaged, and it enhances the squeezing and massaging force of the massage protrusions 23 on the second airbag 20 against the part of the user to be massaged, achieving a better kneading massage effect on the part of the user to be massaged, relaxing the muscles of the part of the user to be massaged, and improving the user's experience.
[0048] The projection of the second airbag 20 completely covers the projection of the first airbag 30, and the projection of the second airbag 20 is larger than the projection of the first airbag 30. Further, the second airbag 20 has a first end close to the flexible connection part 10 and a second end far from the flexible connection part 10. When the airbag is not inflated, the second end of the second airbag 20 is flush with the edge connection structure 33 of the first airbag 30. In this way, when the airbag is inflated, the second end of the second airbag 20 is lifted higher by the first airbag 30, making the squeezing and massaging effect of the massage protrusions 23 on the second airbag 20 against the part to be massaged better. That is to say, when the first airbag 30 is inflated, the first airbag 30 expands and pushes against a part of the second airbag 20 far from the flexible connection part 10, causing the second airbag 20 to rotate around its connection position with the flexible connection part 10 and turn towards the direction close to the flexible connection part 10 with a larger turning amplitude, thereby enhancing the squeezing and massaging force of the massage protrusions 23 on the second airbag 20 against the part of the user to be massaged, improving the massage effect of kneading the part of the user to be massaged, relaxing the muscles of the part of the user to be massaged, and improving the user's experience.
[0049] In an embodiment of the present application, when the airbag is not inflated, the first section 341 and the second partition 35 are located between the first end 24 and the second end 25 of the second airbag 20, and the projection of the first end 24 of the second airbag 20 on the plane where the flexible connection portion 10 is located intersects with the projection of the second section 342 on the plane where the flexible connection portion 10 is located. In this way, when inflated, the part of the first airbag 30 between the second partition 35 and the flexible connection portion 10 is basically not flipped, and when the second airbag 20 is flipped, its first end 24 exactly corresponds to the part of the first airbag 30 between the second partition 35 and the flexible connection portion 10. Therefore, the first end 24 of the second airbag 20 has sufficient flipping space during the flipping process and will not interfere, enabling the second airbag 20 to flip smoothly, so as to perform squeezing massage on the part to be massaged.
[0050] According to another aspect of the present application, a massage device is provided. The massage device includes a wearing body and the airbag as described above, and the flexible connection portion 10 is connected to the wearing body. When a user uses the massage device to massage the part to be massaged, the user wears it on the part to be massaged through the wearing body. Then, when the second airbag 20 is inflated, it expands to form a first-level squeezing massage effect on the user's waist, and when the first airbag 30 is inflated, it expands to push the second airbag 20 to continue squeezing the user's waist again, thereby forming a second-level squeezing massage effect on the user's waist. In this way, during the process of repeatedly inflating and deflating the airbag, the second airbag 20 and the first airbag 30 always work stably and coordinately to repeatedly perform squeezing massage and relaxation on the user's waist, so as to achieve a better kneading massage effect on the user's waist and improve the user's experience.
[0051] In the present application, the part to be massaged includes but is not limited to the waist, legs, arms, etc. Moreover, the wearing body of the massage device generally uses a strap, and the wearing operation is convenient and simple.
[0052] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included within the protection scope of the present application.
