[0037] refer to Figure 1-Figure 7 As shown, an embodiment of the utility model discloses an airbag massage assembly, including a clamping airbag 1 and a supporting airbag 2, wherein the supporting airbag 2 includes a first bag body 21, and the first bag body 21 has a first direction ( Figure 2 and Figure 3 The two clamping airbags 1 are arranged on the first bladder body 21 at intervals along the first direction, and the clamping airbag 1 includes multiple sub-cavities along the second direction ( Figure 2 The clamping capsules 11 are stacked and interconnected (in the middle Z direction), the second direction is the lifting direction of the first capsule 21, and the first direction is perpendicular to the second direction.

[0038] The above-mentioned airbag massage assembly as a whole uses airbags to massage the part of the human body to be massaged. After being deflated, it occupies a small area. When in use, the part to be massaged is placed on the supporting airbag 2 and located between the two clamping airbags 1. The clamping airbags 1 and the supporting airbags 2 are inflated. The supporting airbag 2 can squeeze one side of the part to be massaged, and the two clamping airbags 1 can cooperate with each other to squeeze the other two opposite sides of the part to be massaged, thereby achieving multi-directional squeezing of the part to be massaged, and the massage experience is good. In addition, a plurality of sub-cavities are arranged inside the first capsule body 21 of the supporting airbag 2. When the supporting airbag 2 is inflated, the separation of adjacent sub-cavities will produce pulling between the two capsule surfaces of the first capsule body 21 along the second direction, limiting bulging and forming grooves, thereby forming a plurality of support points corresponding to the number of sub-cavities, and having good stability in the second direction.

[0039] In some embodiments, the two capsule surfaces of the first capsule body 21 in the second direction are connected along the third direction ( Figure 3 The ribs 211 are connected to the first capsule body 21 along the Y direction, and the two sides of the ribs 211 in the second direction are respectively connected to the two capsule surfaces of the first capsule body 21 in the second direction. It should be emphasized that the ribs 211 can be set to be continuous or segmented. If the ribs 211 are set to be continuous, at least one end surface thereof along the third direction is not connected to the capsule surface of the first capsule body 21.

[0040] In other embodiments, the two capsule surfaces of the first capsule body 21 in the second direction are glued or hot-pressed to form a sub-cavity, and the connection position of the gluing or hot-pressing connection (i.e., the separation position of adjacent sub-cavities) forms a connection line extending along the third direction, and the connection line can be continuous or disconnected.

[0041] In order to increase the lifting height of the supporting airbag 2 and further improve the massage experience, the supporting airbag 2 also includes a second bag body 22, which is located above the first bag body 21 and connected to the first bag body 21, and the second bag body 22 is the same size as the first bag body 21.

[0042] In some embodiments, the support airbag 2 adopts an integrated airbag to prevent the second capsule 22 from shifting relative to the first capsule 21. Specifically, the first capsule 21 and the second capsule 22 are connected by multiple groups of connection points distributed along the first direction, and the multiple groups of connection points are arranged in a one-to-one correspondence with the sub-cavities. Each group of connection points includes at least two connection points arranged at intervals along the third direction. The connection points are opened to connect the first capsule 21 and the second capsule 22. The connection points are formed by hot pressing. When the support airbag 2 is inflated, the connection points between the first capsule 21 and the second capsule 22 exist as support points.

[0043] In some embodiments, the first capsule 21 has two sub-cavities, and correspondingly, two groups of connection point groups are provided, and the two groups of connection point groups are at the same distance from the separation positions of the two sub-cavities.

[0044] In some embodiments, the airbag massage assembly is used to massage the legs, and in other embodiments, the airbag massage assembly is used to massage the waist. In the above different embodiments, the spacing distance between the two clamping airbags 1, the size and shape of the clamping airbag 1, and the size and shape of the supporting airbag 2 can be adaptively changed, all within the protection scope of the present utility model.

[0045] In some embodiments, in order to facilitate the inflation of the clamping airbag 1 and the supporting airbag 2, the supporting airbag 2 includes a first air nozzle 23, and the clamping airbag 1 includes a second air nozzle 12, wherein the second air nozzle 12 is arranged on the side of the bottom clamping bag body 11 facing the supporting airbag 2, so as to prevent the second air nozzle 12 from contacting the part to be massaged and generating a foreign body sensation, while the first air nozzle 23 is arranged on the first bag body 21 and is located at the separation position of the two sub-cavities, specifically on the side of the first bag body 21 facing away from the clamping airbag 1. Then, when the supporting airbag 2 and the clamping airbag 1 are inflated, the presence of the first air nozzle 23 and the second air nozzle 12 is not likely to generate a foreign body sensation.

[0046] In some embodiments, the first air nozzle 23 and the second air nozzle 12 are both configured to be L-shaped, so that the air tube used to connect the clamping airbag 1 or the supporting airbag 2 through the first air nozzle 23 and the second air nozzle 12 is not easy to bend during inflation, and is easier to inflate. Furthermore, the end of the first air nozzle 23 away from the first bag body 21 extends along the third direction to reduce the foreign body sensation generated by the air tube connected thereto.

[0047] refer to Figure 5 As shown, in some embodiments, the clamping airbag 1 includes three clamping capsules 11, which are the third capsule, the fourth capsule and the fifth capsule stacked from bottom to top, and the third capsule and the fourth capsule, and the fourth capsule and the fifth capsule are connected by hot pressing, and the corresponding hot pressing positions are opened. Similar to the supporting airbag 2, the third capsule and the fourth capsule, and the fourth capsule and the fifth capsule are connected by two hot pressing points spaced apart along the third direction.

[0048] In some embodiments, the volumes of the third, fourth and fifth capsules are increased in sequence. Under the premise of filling the same gas, the lifting effect of the third and fourth capsules on the fifth capsule is more obvious, and the squeezing effect is better. Of course, in other embodiments, the clamping capsules 11 of the clamping airbag 1 can also be provided with 2, 4 or even more, which will not be described in detail here.

[0049] In some embodiments, the airbag massage assembly also has a clamping bag cover 3, which is used to limit the position of the clamping airbag 1 to prevent the airbag from shifting in a direction other than the expected position, and at the same time, the airbag massage assembly can maintain its appearance after being fully deflated. The clamping bag cover 3 includes a plurality of pockets 31 corresponding to the clamping bag bodies 11 in the clamping airbag 1, and the clamping bag bodies 11 are placed in the pockets 31. The pockets 31 have an opening 31a facing another clamping airbag 1, and a connecting hole 31b is provided between two adjacent pockets 31. Taking the clamping airbag 1 as an example of three clamping bags 11 (the third bag body, the fourth bag body and the fifth bag body respectively), the clamping bag cover 3 includes a first pocket for fitting the third bag body, a second pocket for fitting the fourth bag body and a third pocket for fitting the fifth bag body. The first pocket, the second pocket and the third pocket are stacked from bottom to top and are adapted to the sizes of the third bag body, the fourth bag body and the fifth bag body, that is, the volumes of the first pocket, the second pocket and the third pocket increase in sequence.

[0050] In some embodiments, the clamping bag cover 3 is an integrated bag cover, and the edges of the communication holes 31 b between two adjacent pockets 31 are connected to each other.

[0051] The clamping airbag 1 is connected to the supporting airbag 2 through a connector 20. The connector 20 is disposed on the second airbag 22 and connected to one end of the topmost clamping airbag 11 facing another clamping airbag 1. When the clamping airbag 1 is inflated, it can be fanned out with the connector 20 as the axis. In order to prevent the clamping airbag 11 of the clamping airbag 1 from being separated from the corresponding pocket 31, in some embodiments, the length of the connector 20 is less than the length of the end of the clamping airbag 11 connected to the connector 20, and the length of the opening 31a on the pocket 31 is greater than or equal to the length of the connector 20, and is less than the length of the end of the pocket 31 facing another clamping bag sleeve 3. For example, the connector 20 is centrally disposed on one side of the clamping airbag 11 of the clamping airbag 1, and together with the clamping airbag 11, it forms a T-shaped structure, and one end of the pocket 31 provided with the opening 31a is closed on opposite sides along the extending direction of the opening 31a.

[0052] Specifically, the connecting member 20 is made of the same material as the clamping airbag 1 and is integrally formed with the clamping airbag 1 .

[0053] When the clamping airbag 1 is installed in the clamping bag cover 3, the clamping airbag 1 can be first inserted into the first pocket through the opening 31a of the first pocket, then extended into the second pocket from the opening 31a of the second pocket and the fourth and fifth capsules are moved into the second pocket from the connecting hole 31b between the first and second pockets, and then extended into the third pocket from the opening 31a of the third pocket and the fifth capsule is moved into the third pocket from the connecting part between the second and third pockets. At this time, the clamping capsule 11 corresponds to the pocket 31 one by one, and the closed part of the side of the pocket 31 facing the other clamping bag cover 3 prevents the clamping capsule 11 from detaching from the pocket 31, maintaining the stability between the clamping capsule 11 and the pocket 31. After the clamping capsules 11 are placed one by one in the pocket 31, the connecting piece 20 is hot-pressed to connect with the second capsule 22.

[0054] Alternatively, the connecting piece 20 and the second capsule 22 may be connected by heat pressing first, and then the clamping airbag 1 is stuffed into the third pocket, and then the fourth capsule and the third capsule are transferred in sequence, which will not be described in detail here.

[0056] In some embodiments, the leg massage pad further includes an air source 4, which is connected to the second air nozzles 12 of the two clamping airbags 1 through two first air pipes, and is connected to the first air nozzle 23 of the supporting airbag 2 through the second air pipe.

[0057] refer to Fig. 9 As shown, in some embodiments, the air source 4 includes an air pump 41 and an air valve 42. The air valve 42 is connected to the clamping airbag 1 and the supporting airbag 2 through a first air pipe and a second air pipe. The airbags (including the clamping airbag 1 and the supporting airbag 2) connected to the air pump 41 are adjusted by adjusting the air outlet of the air valve 42, so as to adjust the time of inflation and deflation of the clamping airbag 1 and the supporting airbag 2, thereby performing squeezing or turning over actions.

[0058] In order to realize automatic inflation and deflation, the airbag massage component further includes a control circuit board 5 , which is connected to the air source 4 to control the opening and closing of the air source 4 .

[0059] In some embodiments, the leg massage pad further includes a control box 6, in which the control assembly and the inflation assembly are both disposed, and the control box 6 includes a detachably connected control upper cover and a control lower cover, which can enclose a space for accommodating the above components (including but not limited to the air pump 41, the solenoid valve, and the control circuit board 5). For example, a muffler 43 is also disposed in the control box 6, and the muffler 43 is disposed at the outlet of the air valve 42 to reduce the noise generated during the inflation and deflation process, and it can adopt a muffler similar to an automobile exhaust pipe or other muffler structure, and the muffler 43 is in the prior art and will not be further described in detail. The control upper cover of the control box 6 is also provided with control buttons, which include but are not limited to a switch for starting the air pump 41, a regulating button for adjusting the air outlet of the air valve 42, and the like.

[0060] In some embodiments, the leg massage pad further includes a DC socket and an adapter 8, the DC socket is electrically connected to the control circuit board 5, and the entire airbag massage assembly is connected to the DC socket via the adapter 8 to realize power supply.

[0061] In some embodiments, the leg massage pad further includes a heating element 10 electrically connected to the control circuit board 5. The heating element 10 is fixed in the support pad 9 and is used to heat the massaged area to promote blood flow.

[0062] In some embodiments, the control box 6 is connected to the support pad 9 via a pipe sleeve 7, and a passage is provided in the pipe sleeve 7 for the first air pipe, the second air pipe, and the cable connecting the control circuit board 5 and the heating element 10 to pass through. The pipe can reduce the possibility of the first air pipe, the second air pipe, and the cable being entangled with each other.

[0063] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
