DETAILED DESCRIPTION

[0027] The essential features of the present utility model are further described below in conjunction with the accompanying drawings and specific implementation methods.

[0028] Embodiment 1:

[0029] This embodiment provides a combined airbag.

[0030] like Figure 1 The combined airbag shown is composed of a bag body 1, the top surface of the bag body 1 is provided with a through hole 2 which is exposed upward, and a massage airbag 3 is arranged in the through hole 2, and the massage airbag 3 can be stretched and switched between a massage state in which the top protrudes from the top surface of the bag body 1 and an idle state in which the whole is retracted into the through hole 2. The bag body 1 is provided with a through hole 2 for the massage airbag 3 to be stretched and deformed, and the massage airbag 3 can be stretched and retracted along the axial direction of the through hole 2 and switched between the massage state and the idle state, which ensures that the massage airbag 3 can exert a massage force on the user by bulging the top upward when inflating and switching to the massage state, thereby playing a massage role, and also ensures that the massage airbag 3 can be deflated and switched to the idle state by retracting into the through hole 2 as a whole to eliminate the foreign body sensation to the user, improve the lying comfort, and enhance the user experience.

[0031] In this embodiment, the bladder 1 and the massage airbag 3 are not connected to each other, so that the two can be independently inflated and deflated under the control of the controller 20. The bottom of the bladder 1 is provided with a main air nozzle 10 for adjusting the air pressure. The bladder 1 can adjust the softness and hardness through the inflation and deflation operation to meet the user's requirements for the support of the cushion body. The bottom of the massage airbag 3 is provided with an auxiliary air nozzle 11 (such as Figure 6 As shown), the massage airbag 3 is reciprocated and extended by inflation and deflation, and then uses the extended end to apply a pressing force to the user, thereby forming a massage stimulation.

[0032] In this embodiment, the through hole 2 is vertically through-set, the bottom surface of the bladder body 1 is covered with a base layer 4, the bottom of the massage airbag 3 is fixedly connected to the base layer 4, and the top is inserted into the through hole 2, so that the massage airbag 3 can switch between the massage state and the idle state through vertical expansion and contraction. The base layer 4 is attached to the bottom surface of the bladder body 1 and provides vertical support for the massage airbag 3, so that when the massage airbag 3 is inflated and extended, the top can be driven to protrude upward from the upper port of the through hole 2 under the support of the base layer 4. When in use, the controller 20 controls the hardness of the cushion body by adjusting the air pressure in the bladder body 1. At the same time, the controller 20 realizes expansion and contraction switching by adjusting the air pressure in the massage airbag 3. Specifically, when the controller 20 inflates the massage airbag 3 (such as Figure 2 As shown in FIG. 2 , the massage airbag 3 is extended along its axial direction, and the bottom of the massage airbag 3 is blocked and limited by the base layer 4, so that the top of the massage airbag 3 moves upward and exerts a pressing force on the user after protruding out of the upper end of the through hole 2. When the controller 20 drives the massage airbag 3 to shrink by exhausting air (as shown in FIG. 2 ), the massage airbag 3 is extended along its axial direction, and the bottom of the massage airbag 3 is blocked and limited by the base layer 4, so that the top of the massage airbag 3 moves upward and exerts a pressing force on the user after protruding out of the upper end of the through hole 2. Figure 3 As shown in the figure, the massage airbag 3 contracts along its axial direction, and the bottom of the massage airbag 3 is pulled and limited by the base layer 4, so that the top of the massage airbag 3 moves downward and retracts into the through hole 2, which not only cancels the pressing force on the user, thereby forming a massage experience through reciprocating expansion and contraction, but also eliminates the foreign body sensation by being completely hidden in the through hole 2, thereby improving the user's lying comfort.

[0033] In this embodiment, the capsule 1 is flat, and the top surface of the capsule 1 forms a flat supporting surface. The capsule 1 is provided with through holes 2 arranged in a matrix, and the massage airbags 3 are arranged in the corresponding through holes 2. The capsule 1 is arranged in a flat shape, which is convenient for the capsule 1 to be installed in the cushion body, improving the convenience of assembly, and also convenient for the massage airbags 3 arranged in a matrix, so that each area of ​​the user can receive a balanced pressing force, improving the massage comfort.

[0034] In this embodiment, the capsule 1 includes an upper layer 5 with an upper opening 7, a lower layer 6 with a lower opening 8, and a connecting tube 9 (such as Figure 4As shown in the figure, the periphery of the upper layer 5 and the periphery of the lower layer 6 are hot-melt-bonded to form the capsule 1, and the peripheries of the two ends of the connecting tube 9 are hot-melt-bonded to the corresponding peripheries of the upper opening 7 and the lower opening 8 to form the through hole 2. During production, the periphery of the end of the connecting tube 9 is folded to form a connecting ring that is bonded to the periphery of the upper opening 7 or the periphery of the lower opening 8, which not only ensures the sealing connection between the connecting tube 9 and the upper opening 7 and the lower opening 8, and the sealing of the capsule 1, but also plays a role in limiting the upper layer 5 and the lower layer 6, and can enclose to form a through hole 2 for the massage airbag 3 to penetrate, and plays a role in guiding the deformation of the through hole 2. Specifically, the connecting tube 9 is connected across the upper layer 5 and the lower layer 6, which not only plays a vertical limiting role between the corresponding areas of the upper layer 5 and the lower layer 6 to prevent the local vertical bulging of the bladder 1 and ensure that the top and bottom surfaces of the bladder 1 are flat, but also plays a horizontal limiting role for the upper layer 5 and the lower layer 6 to prevent the top and bottom surfaces of the bladder 1 from being vertically misaligned due to horizontal offset, thereby ensuring that the bladder 1 maintains a flat shape when inflated.

[0035] In this embodiment, the massage airbag 3 is connected to the auxiliary air nozzle 11 through a common air pipe 12, so that the air pressure in the massage airbag 3 is synchronously adjusted (such as Figure 7 The air pressure in the massage airbag 3 is adjusted synchronously by using the shared air pipe 12, which not only effectively simplifies the pipeline structure and reduces the failure rate, but also ensures that the massage airbag 3 improves the massage comfort by applying a pressing force to the user synchronously. The air pipe 12 is arranged below the bladder body 1, and the base layer 4 is preferably a sponge layer. The deformation of the base layer 4 is used to provide a setting space for the air pipe 12 to prevent the air pipe 12 from being compressed and blocked due to local concentrated force.

[0036] In this embodiment, the massage airbag 3 includes at least two vertically stacked unit bags 13 (such as Figure 5 As shown in the figure, vent holes are provided between adjacent unit capsules 13 to adjust the air pressure in the unit capsules 13 synchronously. In a preferred embodiment, the massage airbag 3 includes three vertically stacked unit capsules 13, which not only ensures that the massage airbag 3 has a vertical deformation amplitude that meets the use requirements, but also ensures that the massage airbag 3 can be stretched and deformed in a preset direction to prevent radial bending deformation.

[0037] In this embodiment, the unit capsule 13 includes an upper sheet and a lower sheet stacked vertically, and the peripheries of the upper sheet and the lower sheet are bonded by hot melt. The peripheries of the upper sheet and the lower sheet are bonded by hot melt to form the unit capsule 13, and ventilation holes are provided in the middle of the facing surfaces of adjacent unit capsules 13 and fixedly connected by hot melt bonding, which is convenient for processing and ensures that the massage airbag 3 has good deformation controllability and can be telescopically switched along the axis of the through hole 2.

[0038] Embodiment 2:

[0039] Compared with the first embodiment, this embodiment provides a mattress.

[0040] like Figure 8 The mattress shown is composed of a cushion body and a bedspread 14 wrapping the cushion body, wherein the cushion body includes a comfort layer 15, a functional layer and a spring layer 16 stacked in sequence from top to bottom, wherein the functional layer includes a front sponge 17, a rear sponge 18 and a combined airbag 19 disposed between the front sponge 17 and the rear sponge 18. The front sponge 17, the combined airbag 19 and the rear sponge 18 are assembled to form a functional layer, which not only realizes the functions of support adjustment and massage by arranging the combined airbag 19, but also forms a flat top surface by arranging the front sponge 17 and the rear sponge 18 to cooperate with the combined airbag 19, thereby reducing the cost by reducing the size of the combined airbag 19 and providing stable support for the user.

[0041] In this embodiment, there are at least two combined airbags 19, and the combined airbags 19 are laid out in sequence from front to back. By arranging a plurality of front-to-back distributed combined airbags 19 to correspond to each torso segment of the user one by one, it is ensured that each torso segment of the user obtains differentiated support and massage experience, thereby improving the comfort of use.

[0042] In this embodiment, when the cushion body is a double cushion, the combined airbags 19 are in two groups and are disposed on both sides of the cushion body, so that users disposed on both sides of the cushion body can control the combined airbags 19 according to their own needs, thereby meeting the differentiated usage needs of the users.

[0043] In this embodiment, a controller 20 is provided in the rear sponge 18, and the controller 20 independently inflates and deflates the bladder body 1 and the massage airbag 3. The controller 20 is arranged in the rear sponge 18, which not only effectively shortens the distance between the controller 20 and the combined airbag 19, facilitates the laying of pipelines, but also keeps it away from the user's head, thereby reducing the impact on the user's sleep.

[0044] The other structures and effects of the combined airbag 19 of the present invention are consistent with those of the first embodiment and will not be described in detail.
