Description

Technical Field

[0001] The utility model relates to the field of bedding, in particular to an air bag, an air cushion and an air bag pillow. Background Art

[0002] The existing pillow is provided with an inflatable airbag, which can adjust the vertical height by inflating and deflating, thereby providing massage stimulation to the user. The top of the existing airbag is provided with convex points to form a massage part. Due to the limited extension range of the massage part, the massage stimulation is small, and the user cannot be provided with a comfortable massage stimulation, which affects the user experience. Utility Model Content

[0003] In order to address the deficiencies in the prior art, the utility model provides an airbag, an air cushion and an airbag pillow, which provide vertical support for the massage part by arranging a support part, and then increase the massage stimulation by increasing the vertical extension range of the massage part, thereby improving the massage comfort and user experience.

[0004] The utility model is realized in the following manner: an airbag, comprising a capsule body with a capsule cavity, characterized in that a massage part with convex points is provided in the middle of the top surface of the capsule body, and a support part is formed at the bottom of the capsule body. When the capsule body is inflated, the support part bulges upward and supports the massage part, and the massage part forms a massage stimulation transmitted upward through the convex points that bulge upward. A support part is arranged at the lower part of the capsule body, and the support part can not only support the massage part by being inflated and hardened, but also play a role in lifting the massage part as a whole, and enhance the massage stimulation by increasing the vertical displacement stroke of the convex points, thereby improving the massage comfort and enhancing the user experience. The capsule body is formed by blow molding. During the blow molding process, the height of the support part is greater than the height of the massage part, and the material at the support part will become thinner due to vertical stretching, resulting in a softer support part. The convex points at the center of the massage part will be basically planar due to the small vertical stretching amplitude, resulting in the convex points having the characteristics of being thicker and harder, and having a harder touch relative to other positions in the massage part, effectively improving the massage experience.

[0005] Preferably, the top surface periphery of the capsule is concave downward to form a retractable deformation annular groove, and when the capsule is inflated, the deformation annular groove is pulled radially to make the convex point bulge upward. The deformation annular groove can be radially pulled and deformed when the capsule is inflated, thereby increasing the height of the convex point upward by increasing the radial size of the top surface periphery of the capsule, effectively enhancing the massage stimulation.

[0006] Preferably, the vertical cross-sectional profile of the deformation ring groove is in the shape of an arc with a downward depression in the middle. The arc-shaped deformation ring groove has the characteristic of low noise during deformation, which effectively reduces the influence of the deformation ring groove on the user's sleep during deformation.

[0007] Preferably, the vertical cross-sectional profile of the deformation ring groove is V-shaped with the middle portion concave downward, and the V-shaped deformation ring groove has a large radial dimension change, which can provide a large vertical deformation distance for the protrusion, thereby improving the comfort of use by enhancing massage stimulation.

[0008] Preferably, the support part is cylindrical, and a transition fillet is provided at the periphery of the bottom thereof. The cylindrical support part has good controllability of deformation, ensuring that the support part can generate vertical supporting force and that the massage part can be effectively lifted. The transition fillet is provided at the periphery of the bottom surface of the support part, which can effectively disperse the vertical force and ensure that the support part maintains the vertical posture of the axis, and can also redirect the vertical force through the transition fillet, and match the transition fillet with the wall surface at the installation station, thereby ensuring the stability of the support part by improving the diffusion effect.

[0009] Preferably, the capsule body comprises an upper sheet and a lower sheet, which are vertically stacked and bonded to form the capsule cavity through peripheral bonding. The upper sheet and the lower sheet are independently processed and stacked and bonded to form the capsule body, which is convenient for batch processing and improves production efficiency, and also ensures that the upper sheet and the lower sheet can be deformed in a preset direction when the capsule cavity is inflated, thereby ensuring that the massage stimulation can be accurately transmitted upward.

[0010] Preferably, a sponge block is provided in the bladder cavity to reduce the volume change amplitude of the bladder body when the air is deflated. The sponge block can maintain the contour of the bladder body when the air pressure in the bladder cavity drops, which can shorten the time interval between inflation and deflation by reducing the volume change of the bladder body, thereby increasing the frequency of massage stimulation, and can also reduce noise by reducing the deformation amplitude of the bladder body, thereby reducing the impact on the user's sleep.

[0011] An air cushion using the airbag comprises a cushion body, the cushion body comprises a gasket, an airbag and an air tube arranged on the gasket, the airbag is inflated and deflated through the air tube and drives the convex point to rise to form massage stimulation. A plurality of airbags are arranged on the cushion body to form a plurality of stations for applying massage stimulation to the user, which can not only apply massage stimulation to all areas of the user's surface to improve comfort, but also ensure that all areas of the cushion body can apply massage stimulation to the user when the user flips over, thereby improving the user experience.

[0012] Preferably, the airbags are arranged in a matrix on the pad. The airbags are arranged in a matrix to ensure that there are a uniform number of airbags in each area of ​​the pad, thereby ensuring that the user can receive the same massage stimulation in each area of ​​the pad. The pad plays a role in connecting and positioning the airbags.

[0013] Preferably, the airbags in the spaced rows are interconnected, so that the air cushion has two groups of airbags that can be independently controlled to be inflated and deflated. By independently controlling the two groups of airbags, the cushion body can have a variety of massage stimulations, thereby improving the massage experience.

[0014] Preferably, the air cushion comprises an upper substrate and a lower substrate, which are vertically stacked and bonded to form the airbag, the trachea and the gasket. The upper sheets of each capsule are processed on the same upper substrate, and the lower sheets of each capsule are processed on the same lower substrate. The cushion body is obtained by stacking and bonding the upper substrate and the lower substrate, which effectively simplifies the processing procedure and effectively improves the processing efficiency.

[0015] An airbag pillow using the air cushion comprises a pillow body supporting the air cushion and a control box for adjusting the air pressure in the air cushion. The airbag forms a massage stimulus transmitted upward by inflating and deflating the air. The control box adjusts the air pressure in the airbag in the air cushion, and then obtains the massage stimulus transmitted upward by controlling the vertical expansion and contraction deformation of the airbag, providing a comfortable massage experience for the user.

[0016] The beneficial effects of the utility model are as follows: a support part is arranged at the lower part of the sac body, which can not only support the massage part by being inflated and hardened, but also lift the massage part as a whole, and enhance the massage stimulation by increasing the vertical displacement stroke of the convex point, thereby improving the massage comfort and enhancing the user experience.

DETAILED DESCRIPTION

[0026] The essential features of the present utility model are further described below in conjunction with the accompanying drawings and specific implementation methods.

[0027] Embodiment 1:

[0028] This embodiment provides an airbag.

[0029] like Figure 1 An airbag is shown, comprising a bag body 1 with a bag cavity therein, a massage part 3 with a convex point 2 being provided in the middle of the top surface of the bag body 1, a support part 4 being formed at the bottom of the bag body 1, and when the bag body 1 is inflated, the support part 4 bulges upward and supports the massage part 3, and the massage part 3 forms a massage stimulation transmitted upward through the convex point 2 that bulges upward. The support part 4 is provided at the lower part of the bag body 1, and the support part 4 can not only support the massage part 3 by being inflated and hardened, but also lift the massage part 3 as a whole, and enhance the massage stimulation by increasing the vertical displacement stroke of the convex point 2, thereby improving the massage comfort and enhancing the user experience.

[0030] In this embodiment, the capsule 1 is connected through the capsule cavity, the top of the capsule 1 forms a massage part 3, and the bottom forms a support part 4. The massage part 3 and the support part 4 are connected to each other and can be inflated and deflated synchronously. When the capsule 1 is inflated, the massage part 3 and the support part 4 are inflated at the same time. The support part 4 is inflated and plays a role in lifting the massage part 3, providing effective support for the massage part 3. The massage part 3 is inflated and vertically extended, so that the protrusion 2 is lifted upward and forms an upward massage stimulation, thereby ensuring that the user has a comfortable massage experience.

[0031] In this embodiment, the massage part 3 includes a convex point 2 and a deformation annular groove 5 arranged around the convex point 2, and the deformation annular groove 5 can be radially retracted. When the bladder 1 is inflated, the deformation annular groove 5 is radially pulled to make the convex point 2 bulge upward and obtain a vertical retractable stroke. The deformation annular groove 5 can switch between a contracted state and an extended state, and can reduce the thickness of the massage part 3 by switching to the contracted state, thereby eliminating the foreign body sensation caused by the massage part 3 to the user, and can lift the convex point 2 by switching to the extended state, thereby applying massage stimulation to the user.

[0032] In this embodiment, the periphery of the top surface of the sac 1 is recessed downward to form a retractable deformation annular groove 5. When the deformation annular groove 5 switches to a contracted state, the middle part of the deformation annular groove 5 is recessed downward, which can not only hide the deformation annular groove 5 and effectively eliminate the foreign body sensation, but also ensure that the deformation annular groove 5 can switch to an extended state along a preset path when the sac 1 is inflated.

[0033] In this embodiment, the vertical cross-sectional profile of the deformation annular groove 5 is V-shaped with a downward depression in the middle (eg Figure 3 As shown in the figure, the deformation ring groove 5 increases the vertical deformation amplitude by increasing the groove cavity depth, so that the protrusion 2 produces a stronger massage stimulation by lifting a greater distance.

[0034] In this embodiment, the support part 4 is columnar, and a transition fillet 6 is provided on the periphery of the bottom thereof. The columnar support part 4 has good vertical support performance after being inflated, and can not only play a vertical lifting role on the massage part 3, the vertical deformation distance of the support part 4 can be converted into the lifting distance of the convex point 2, but also provide effective support for the massage part 3, ensure that the bottom surface of the massage part 3 is maintained at a set height, ensure that the vertical deformation generated by the massage part 3 can be converted into the lifting distance of the convex point 2, and ensure that the convex point 2 can produce a massage stimulation of a preset intensity.

[0035] In this embodiment, the capsule 1 includes an upper sheet 7 and a lower sheet 8 (such as Figure 2 As shown in the figure, the upper sheet 7 and the lower sheet 8 are vertically stacked and adhered to each other through the periphery to enclose the capsule cavity. The upper sheet 7 and the lower sheet 8 are independently processed and formed into the capsule body 1 through stacking and adhesion, which not only simplifies the processing steps and improves the processing efficiency, but also reduces the processing difficulty and reduces the processing cost. The upper sheet 7 and the lower sheet 8 can be formed by injection molding or vacuum forming process, ensuring that the upper sheet 7 and the lower sheet 8 form the massage part 3 and the support part 4 respectively after the periphery is adhered to each other.

[0036] It can be understood that a sponge block 9 is provided in the bladder cavity to reduce the volume change amplitude of the bladder body 1 when it is deflated. The sponge block 9 can maintain the contour of the bladder cavity by its own elasticity, thereby preventing the bladder cavity from completely collapsing after deflation, and effectively reducing the volume change of the bladder cavity during inflation and deflation, thereby increasing the frequency of massage stimulation by shortening the single inflation and deflation time, and reducing noise by reducing the volume change of the bladder cavity, thereby reducing the impact on the user's sleep.

[0037] It can be understood that the vertical cross-sectional profile of the deformation annular groove 5 is in the shape of an arc with a downward depression in the middle (eg Figure 4 As shown in the figure, the deformation ring groove 5 with an arc-shaped cross-section has both a good vertical deformation amplitude and a small deformation noise, which not only meets the massage needs of the user, but also reduces the impact on the user's sleep by reducing the deformation noise.

[0038] Embodiment 2:

[0039] Compared with the first embodiment, this embodiment provides an air cushion.

[0040] like Figure 5 The air cushion shown comprises a cushion body 14, wherein the cushion body 14 comprises a gasket 10, an airbag and an air tube 11 arranged on the gasket 10, wherein the airbag is inflated and deflated through the air tube 11 and drives the convex point 2 to rise to form a massage stimulation. A plurality of airbags are arranged on the cushion body 14, so that each airbag can form a massage stimulation applied to the user by inflating and deflation, which can ensure that the user can still be massaged by the airbag below after moving along the top surface of the cushion body 14, and also improve the massage comfort by increasing the number of airbags acting on the user at the same time.

[0041] In this embodiment, the airbags are arranged in a matrix on the gasket 10, and the airbags in alternate rows are connected to each other (such as Figure 6 As shown in the figure, the air cushion has two groups of independently controllable air-inflation and air-releasing bladders 1. The air bladders on the cushion body 14 are divided into two groups that can be independently controlled, so that the two groups of air bladders can independently act and apply massage stimulation to the user, which is convenient for operation and can form different massage experiences through mutual cooperation, thereby improving massage comfort.

[0042] In this embodiment, the air cushion includes an upper substrate 12 and a lower substrate 13 (such as Figure 7 As shown), the upper substrate 12 and the lower substrate 13 are vertically stacked, adhered and enclosed to form the airbag, trachea 11 and gasket 10. The upper substrate 12 and the lower substrate 13 are formed by independent processing, and the upper substrate 12 is provided with a dispersed upper sheet 7, and the lower substrate 13 is provided with a dispersed lower sheet 8. The upper substrate 12 and the lower substrate 13 are vertically stacked, and the upper substrate 12 is located in the peripheral area of ​​the upper sheet 7 and the lower substrate 13 is located in the peripheral area of ​​the lower sheet 8. They are vertically stacked and adhered to form the gasket 10. The upper sheet 7 and the lower sheet 8 are vertically aligned and enclosed to form the capsule 1. At the same time, the gasket 10 is formed with a trachea 11 connected to the same group of capsules 1, so that the same group of capsules 1 can achieve synchronous inflation and deflation operations through the trachea 11.

[0043] In this embodiment, the upper substrate 12 and the lower substrate 13 can be formed by injection molding or vacuum forming, which is convenient for processing and reduces the difficulty of processing.

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

[0045] Embodiment three:

[0046] Compared with the second embodiment, this embodiment provides an airbag pillow.

[0047] like Figure 8 The airbag pillow shown includes a pillow body 15 supporting an air cushion and a control box 16 for adjusting the air pressure in the air cushion. The airbag 1 forms a massage stimulus transmitted upward by inflating and deflation. The air cushion is laid on the top surface of the pillow body 15. The airbag in the air cushion forms a massage stimulus applied upward by inflating and deflation. The user receives the massage stimulus to get a massage experience, which effectively improves the lying comfort of the pillow body 15.

[0048] In this embodiment, the airbag pillow includes a control box 16 externally disposed on the cushion body 14. An air pump assembly is disposed in the control box 16. The air pump assembly inflates and deflates the airbags on the air cushion so that the airbags form massage stimulation through vertical expansion and contraction.

[0049] The other structures and effects of the air cushion described in this embodiment are consistent with those in the second embodiment and will not be described in detail.
