Description

Technical Field

[0001] This utility model relates to the field of bedding, specifically to a massage airbag, a massage pad, and a mattress. Background Technology

[0002] Existing massage airbags include a body that can extend and retract vertically to form a support surface at the top center of the body, allowing upward pressure to be applied. A frustum is located in the center of the massage airbag. This frustum has good deformation resistance, ensuring that the airbag can apply pressure to the user's surface when inflated, thus providing the desired massage stimulation. However, when the airbag deflates, the frustum cannot be effectively compressed due to its good deformation resistance, causing the user to experience a foreign body sensation from squeezing the frustum, reducing sleep comfort and affecting the user experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a massage airbag, a massage pad, and a mattress. A truncated cone is suspended at the top center of the airbag, creating a deformation space below the truncated cone. This ensures that the truncated cone can be raised vertically and exert a pressing force on the user, while also allowing the airbag to sink downwards into the deformation space after deflation, reducing the feeling of foreign objects and improving the user experience.

[0004] This invention is achieved through the following method: a massage airbag includes a body, with a suspended truncated cone at the center of the top of the body. The top surface of the truncated cone has a supporting surface. The body is inflated, causing the supporting surface to rise upwards. The truncated cone is suspended at the center of the top of the body, forming a deformation space below it. This allows the truncated cone, with its good structural strength, to exert a pressing force on the user during vertical lifting, and also allows the body to sink downwards into the deformation space after deflation, reducing the feeling of foreign object and improving the user experience.

[0005] Preferably, the capsule includes a top wall and a bottom wall that are vertically stacked and fixed together. The top wall is integrally formed, and its center and periphery are bent to form a truncated cone and a corner portion surrounding the truncated cone. The truncated cone and the top wall are concentrically arranged. The integral forming of the top wall ensures a sealed connection between the truncated cone and the corner portion, and also facilitates batch processing and assembly. The connection with the integrally formed bottom wall is completed in a single welding operation, effectively reducing processing difficulty and improving processing efficiency. The concentric arrangement of the truncated cone and the top wall ensures that the truncated cone receives support from the top wall, guaranteeing that the truncated cone can be vertically raised and lowered in a horizontal position.

[0006] Preferably, the truncated cone is suspended above the middle of the bottom wall, so that the capsule is positioned below the truncated cone with reserved deformation space. The deformation space will not affect the upward lifting of the truncated cone when the capsule is inflated, and will also provide the necessary space for the truncated cone to be hidden when the capsule is deflated, effectively reducing the foreign object sensation of the truncated cone to the user and improving the user experience.

[0007] Preferably, the corner portion includes an upper corner and a lower corner formed by repeatedly bending vertically outward radially from the bottom edge of the frustum. The bladder switches between a contracted state (closed at the corner) and a bulging state (expanded at the corner) by inflating and deflating the bladder. The periphery of the top wall forms a W-shaped folded surface by alternately setting upper and lower corners, which facilitates unfolding and ensures that the bladder switches to the bulging state. It also reduces the thickness of the bladder by folding and closing, making it easier to switch to the contracted state.

[0008] Preferably, when the capsule is in a contracted state, the supporting surface is flush with the upper corner, and the ratio of the height of the truncated cone to the height of the capsule is A, 0.4≤A≤0.6. This increases the structural strength by increasing the height of the truncated cone, ensuring that the capsule can apply a pressing force to the user through the raised truncated cone when it switches to a raised state. It also limits the height of the truncated cone to reserve sufficient height for the deformation space, ensuring that the truncated cone can be hidden downward into the deformation space when the capsule is in a contracted state and is squeezed by the user, effectively eliminating the feeling of foreign objects.

[0009] Preferably, the bottom edge of the frustum is provided with a horizontal annular surface extending outward, and the outer edge of the horizontal annular surface is bent upward to form an upper corner concentric with the frustum. The horizontal annular surface not only connects the frustum and the adjacent upper corner, but also increases the distance between the frustum and the adjacent upper corner, thereby allowing the frustum to rise and fall independently and complete the action of entering the deformation space, improving the flexibility of the frustum's lifting and lowering.

[0010] Preferably, the upper and lower corners are both annular and alternately arranged radially along the top wall of the capsule. The alternating upper and lower corners can guide the top wall to fold into a W shape, ensuring that the truncated cone is always located in the middle of the top wall and that the truncated cone can be raised and lowered vertically and smoothly.

[0011] Preferably, there are at least two upper corners, which can guide the precise deformation of the top wall and reduce the distance between adjacent upper and lower corners by increasing the number of folds, thereby reducing the thickness of the capsule when it is in a contracted state and reducing the feeling of a foreign body.

[0012] Preferably, the angle between the horizontal annular surface and the outer wall of the frustum is an obtuse angle, ensuring that the frustum can form a contour that is smaller at the top and larger at the bottom. By reducing the area of ​​the supporting surface, the pressing force is concentrated on the user, thereby increasing the intensity of the massage stimulation.

[0013] Preferably, the inner edge of the horizontal annular surface and the bottom edge of the outer wall of the frustum are connected by a rounded corner. The rounded corner disperses stress, prevents irreversible bending of the top wall due to stress concentration, and facilitates processing.

[0014] A massage pad includes massage airbags arranged in a matrix, with adjacent airbags connected by air channels. The matrix arrangement of the massage airbags ensures that all areas of the user's surface receive massage stimulation. The interconnected air channels between adjacent airbags allow for synchronized adjustment of air pressure within them, thereby controlling the synchronized massage stimulation generated by each airbag and enhancing the user experience.

[0015] A mattress includes a massage pad, a limiting pad surrounding the massage pad, and a support pad disposed below the massage pad. The support pad is used to adjust the firmness of the mattress and effectively support the massage pad, which provides massage stimulation to the user through stretching and deformation, effectively enhancing the user experience.

[0016] The beneficial effects of this utility model are as follows: The truncated cone is suspended at the top center of the capsule, and a deformation space is formed below the truncated cone. This allows the truncated cone, which has good structural strength, to exert a pressing force on the user when it is lifted vertically. It also allows the capsule to sink downward into the deformation space after the air is released, reducing the feeling of foreign objects and improving the user experience.

[0023] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1:

[0025] This embodiment provides a massage airbag.

[0026] like Figure 1 and 2The massage airbag 8 shown includes a body with a suspended frustum 1 at the top center. The top surface of the frustum 1 has a support surface 2. Inflating the body causes the support surface 2 to rise. The frustum 1 is suspended at the top center of the body, forming a deformation space 3 below it. This design allows the structurally strong frustum 1 to exert a pressing force on the user during vertical lifting, and also allows the body to sink downwards into the deformation space 3 after deflation, reducing any foreign body sensation and improving the user experience.

[0027] In this embodiment, the bladder contains a cavity isolated from the outside world. The bladder expands and contracts vertically by inflating and deflating, switching between a contracted and bulging state. When inflated, the air pressure inside the bladder increases, the angle at the corners widens, and the truncated cone 1 rises due to the vertical bulging of the bladder, switching to the bulging state. This applies pressure to the user's surface, creating a massage stimulation. When deflated, the air pressure inside the bladder decreases, the angle at the corners narrows, and the truncated cone 1 descends due to the vertical contraction of the bladder, switching to the contracted state.

[0028] In this embodiment, the truncated cone 1 is shaped like a smaller top and a larger bottom. This not only effectively reduces the top surface area of ​​the truncated cone 1, thereby reducing the area of ​​the supporting surface 2 to concentrate the pressing force on the user and increase the intensity of the massage stimulation, but also utilizes the structure of the truncated cone 1 itself to obtain better resistance to deformation, ensuring that the force generated by the inflation of the bladder can be transmitted to the user's surface through the truncated cone 1, improving the efficiency of force transmission. Furthermore, after the massage airbag 8 is deflated, the deformation space 3 can be used to house the truncated cone 1, ensuring that the user's weight is distributed across the top wall of the bladder, so that the user will not experience a foreign body sensation due to squeezing the truncated cone 1.

[0029] In this embodiment, the frustum 1 is suspended above the middle of the bottom wall, so that the capsule is located below the frustum 1 with a reserved deformation space 3. The vertical projection of the frustum 1 falls completely into the deformation space 3, ensuring that the frustum 1 can sink downward into the deformation space 3 when subjected to force. By reducing the lifting resistance of the frustum 1, the lifting flexibility is improved, thereby effectively reducing the force required to trigger the frustum 1 to sink.

[0030] In this embodiment, when the capsule is in a contracted state, the supporting surface 2 is flush with the upper corner 4, and the height ratio of the truncated cone 1 to the capsule is A, where 0.4 ≤ A ≤ 0.6. Preferably, A = 0.5. This increases the structural strength of the truncated cone 1 by increasing its height, ensuring that the capsule can apply pressure to the user through the raised truncated cone 1 when switching to a raised state. Furthermore, limiting the height of the truncated cone 1 provides sufficient height for the deformation space 3, ensuring that the truncated cone 1 can be hidden downwards into the deformation space 3 when the capsule is in a contracted state and is compressed by the user, effectively eliminating the feeling of a foreign object.

[0031] In this embodiment, a horizontal annular surface 6 extending outward is provided at the bottom edge of the frustum 1. The outer edge of the horizontal annular surface 6 is bent upward to form an upper corner 4 concentrically arranged with the frustum 1. The inner edge of the horizontal annular surface 6 is connected to the frustum 1, and the outer edge is connected to the corner. This increases the distance between the frustum 1 and the corner, thereby increasing the vertical projection area of ​​the deformation space 3 of the frustum 1, which facilitates the downward concavity of the frustum 1. It also ensures a sealed connection with the corner when the frustum 1 is raised and lowered independently.

[0032] In this embodiment, the capsule includes a top wall and a bottom wall that are vertically stacked and fixed together. Both the top and bottom walls are integrally formed. The center and periphery of the top wall are bent to form the frustum 1 and a corner portion (e.g., around the frustum 1) Figure 3 As shown in the figure, the frustum 1 and the top wall are arranged concentrically.

[0033] In this embodiment, the angle between the horizontal annular surface 6 and the outer wall of the frustum 1 is an obtuse angle. The increase of the angle reduces the range of change of the angle, which facilitates the upward lifting of the frustum 1 when the bladder is inflated.

[0034] In this embodiment, the inner edge of the horizontal annular surface 6 and the bottom edge of the outer wall of the frustum 1 are connected by a rounded corner 7, which effectively disperses stress, prevents irreversible excessive deformation at the connection between the frustum 1 and the horizontal annular surface 6 due to local stress concentration, effectively extends the service life of the massage airbag 8, and facilitates processing and production.

[0035] In this embodiment, the corner portion includes an upper corner 4 and a lower corner 5 formed by repeatedly bending vertically outward radially from the bottom edge of the frustum 1. The bladder switches between a contracted state (closed at the corner) and a bulging state (expanded at the corner) by inflating and deflating the bladder. The periphery of the top wall, located outside the frustum 1, forms the upper corner 4 and lower corner 5 by vertical bending. This not only increases the folding efficiency by repeatedly bending into a W shape, ensuring a smaller thickness when the bladder switches to the contracted state, thus reducing the feeling of foreign body, but also allows for greater vertical deformation stroke through vertical expansion, thereby increasing the pressure force and enhancing massage stimulation.

[0036] In this embodiment, both the upper corner 4 and the lower corner 5 are annular and alternately arranged radially along the top wall of the bladder. Both corners are concentric with the truncated cone 1, ensuring that all areas around the bladder have the same deformation resistance. This ensures that each area guides the truncated cone 1 to rise and fall vertically along the bladder axis through synchronous deformation, ensuring that the bladder achieves expansion and contraction deformation in a preset manner and preventing irreversible deformation that would prevent the bladder from failing to provide massage stimulation. The distance between adjacent upper corners 4 and lower corners 5 along the radial direction of the top wall of the bladder is the same. This ensures that the angles of the upper corners 4 and lower corners 5 can change synchronously during the expansion and contraction of the bladder, and also ensures that the radial distance between the vertical projections of adjacent upper corners 4 and lower corners 5 remains the same. By setting balanced deformation resistance, the truncated cone 1 is guided to rise and fall vertically.

[0037] In this embodiment, there are at least two upper corners 4. By increasing the number of upper corners 4 and lower corners 5, the distance between adjacent upper corners 4 and lower corners 5 is reduced, thereby reducing the thickness of the capsule when it switches to a contracted state and effectively eliminating the feeling of a foreign body. The number of upper corners 4 and lower corners 5 can be adjusted as needed, and all should be considered as specific embodiments of this utility model.

[0038] Example 2:

[0039] Compared to Embodiment 1, this embodiment provides a massage pad.

[0040] like Figure 4 The massage pad 9 shown includes the massage airbags 8 arranged in a matrix, with adjacent airbags connected by air channels 12. The matrix arrangement of the massage airbags 8 ensures that all areas of the user's surface receive massage stimulation, thereby enhancing massage comfort.

[0041] In this embodiment, adjacent massage airbags 8 are connected by air passages 12 to ensure that the air pressure inside adjacent massage airbags 8 can be adjusted synchronously. This not only simplifies the control system and makes it easy to operate, but also ensures that the relative positions of adjacent massage airbags 8 remain fixed.

[0042] The structure and effect of the massage airbag described in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

[0043] Example 3:

[0044] Compared to Embodiment 2, this embodiment provides a mattress.

[0045] like Figure 5The mattress shown includes the massage pad 9, a limiting pad 10 that surrounds the massage pad 9, and a support pad 11 located below the massage pad 9. The limiting pad 10 clamps, positions, and protects the massage pad 9, ensuring that the massage airbags 8 on the massage pad 9 are adjusted in a preset position by inflation and deflation. This ensures that the massage pad 9 can apply massage stimulation in a preset direction, improving massage comfort, and also effectively prevents interference between adjacent massage pads 9. The support pad 11 supports the massage pad 9, ensuring that the vertical extension and contraction of the massage pad 9 is converted into an upward pressing force, thereby increasing the intensity of the massage stimulation.

[0046] In this embodiment, the limiting pad 10 is provided with perforations. The number and position of the perforations are matched one by one with the massage airbags 8 on the massage pad 9. During installation, the limiting pad 10 wraps around the massage pad 9, and the perforations are fitted onto the corresponding massage airbags 8, so that each massage airbag 8 is limited by the inner wall of the perforation, ensuring that the massage airbag 8 can achieve vertical extension and contraction under the guidance of the perforation, thereby generating massage stimulation applied to the user and providing the user with a comfortable massage experience.

[0047] The structure and effect of the massage pad described in this embodiment are the same as those in Embodiment 2, and will not be repeated here.
