DETAILED DESCRIPTION

[0024] The essence of the utility model is further explained below in conjunction with the drawings and specific embodiments.

[0025] Example 1:

[0026] This embodiment provides a massage airbag.

[0027] like Figure 1 and 2 The massage airbag 11 shown includes a body with a vertically movable boss 1 in the center. The boss 1 includes a frustum-shaped cavity 2 and a cylindrical cavity 3 that are interconnected. The cylindrical cavity 3 is stacked on top of the frustum-shaped cavity 2, and its diameter is smaller than the top diameter of the frustum-shaped cavity 2 to reduce the top surface area of ​​the boss 1. The cylindrical cavity 3, with vertically arranged sidewalls, effectively improves the deformation resistance of the top of the boss 1, ensuring that the top of the boss 1 maintains its contour when in contact with the user. This effectively limits the support surface area, ensuring that the intensity of the massage stimulation meets the usage requirements and preventing the intensity of the massage stimulation from decreasing due to the increased support surface area, thus improving the user experience.

[0028] In this embodiment, the bladder contains a cavity isolated from the outside world. The bladder expands and contracts vertically by inflating and deflating air, switching between a contracted and bulging state. When inflated, the air pressure inside the bladder increases, causing the protrusion 1 to rise due to the vertical bulging of the bladder. This applies pressure to the user's surface, creating a massage stimulation. The top of the protrusion 1 has a cylindrical cavity 3. The vertically arranged sidewalls of the cylindrical cavity 3 enhance the vertical pressure-bearing capacity of the top of the protrusion 1, preventing deformation when pressure is applied to the user. This ensures that the supporting surface area formed by the top surface of the protrusion 1 remains constant, preventing a decrease in massage stimulation due to an increased supporting surface area and ensuring massage comfort.

[0029] In this embodiment, the cylindrical cavity 3 and the frustum cavity 2 are coaxially arranged. Both the cylindrical cavity 3 and the frustum cavity 2 are connected to the bladder cavity, which facilitates the synchronous adjustment of air pressure in different areas of the bladder, thereby ensuring synchronous deformation of different areas of the bladder in the circumferential direction. This ensures that the protrusion 1 can rise and fall vertically along the axis of the bladder in a stable posture, thereby applying massage stimulation in a preset direction.

[0030] In this embodiment, the boss 1 is formed by bending at the center of the top wall. The sidewall of the boss 1 includes a vertical annular surface 4, a horizontal annular surface 5, and an oblique annular surface 15 connected sequentially from top to bottom (e.g., ...). Figure 3 (As shown). The inner edge of the vertical annular surface 4 is integrally connected to the periphery of the supporting surface, the inner edge of the horizontal annular surface 5 is integrally connected to the outer edge of the vertical annular surface 4, and the outer edge of the horizontal annular surface 5 is integrally connected to the inner edge of the inclined annular surface 15. This ensures that the top center can be bent to form vertically stacked cylindrical cavities 3 and frustum cavities 2, which facilitates integral processing and ensures sealing.

[0031] In the embodiment, the junctions between the outer edge of the horizontal torus 5 and the top edge of the oblique torus 15 and between the inner edge of the horizontal torus 5 and the bottom edge of the vertical torus 4 are bevels, which are convenient for processing and can form creases for guiding the deformation of the side wall of the boss 1, ensuring the accurate deformation of the boss 1. In addition, the junctions can also be fillets (as shown in Figure 4 the embodiment), including an outer fillet 6 between the outer edge of the horizontal torus 5 and the top edge of the oblique torus 15 and an inner fillet 7 between the inner edge of the horizontal torus 5 and the bottom edge of the vertical torus 4, which effectively disperses stress and prevents excessive deformation of the side wall of the boss 1 due to local stress concentration, and should also be considered as a specific embodiment of the embodiment.

[0032] In the embodiment, the capsule body includes a vertically stacked and adhered top wall and bottom wall, both of which are integrally processed and formed, the top wall is stacked on the bottom wall and the perimeters of the two are welded and fixed, which not only ensures the isolation of the capsule cavity from the outside space, facilitates the adjustment of air pressure, and generates upward massage stimulation, but also improves processing efficiency by reducing the number of welds and reduces the risk of air leakage by reducing the area of the weld.

[0033] In the embodiment, the top wall forms the boss 1 and the corner portion surrounding the boss 1 by bending, and the corner portion includes an upper corner 8 and a lower corner 9 formed by vertically repeated bending from the inside to the outside of the top wall, so that the capsule body can be switched between a retracted state in which the corner portion is retracted and a raised state in which the corner portion is expanded. The perimeters of the top wall outside the boss 1 are formed by vertically bending to form the upper corner 8 and the lower corner 9, which can form a W shape by repeated bending, effectively increase the folding efficiency, ensure that the capsule body has a smaller thickness when switched to the retracted state, and also can obtain a larger vertical deformation stroke by vertical expansion, thereby increasing the pressing force to improve massage stimulation.

[0034] In the embodiment, the top surface of the boss 1 forms a supporting surface, the supporting surface is arranged flush with the upper corner 8 when the capsule body is in the retracted state, and the bottom surface of the boss 1 is arranged flush with the lower corner 9, so that the upper corner 8 and the supporting surface can simultaneously support the user, thereby increasing the contact area between the capsule body and the surface of the user to disperse the force, thereby reducing the foreign body sensation.

[0035] In this embodiment, both the upper corner 8 and the lower corner 9 are annular and alternately arranged radially along the top wall of the bladder. Both corners are concentric with the protrusion 1, ensuring that all areas around the bladder have the same deformation resistance. This ensures that each area guides the protrusion 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 8 and lower corners 9 along the radial direction of the top wall of the bladder is the same. This ensures that the angles of the upper corners 8 and lower corners 9 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 8 and lower corners 9 remains the same. By setting balanced deformation resistance, the protrusion 1 is guided to rise and fall vertically.

[0036] In this embodiment, there are at least two upper corners 8 and at least two lower corners 9. The number of upper corners 8 and lower corners 9 can be adjusted as needed, and all of them should be regarded as specific embodiments of this utility model.

[0037] Example 2:

[0038] Compared to Embodiment 1, this embodiment provides a massage pad.

[0039] like Figure 5 The massage pad 12 shown includes the massage airbags 11 arranged in a matrix, with adjacent airbags 11 connected by air channels 10. The matrix arrangement of the massage airbags 11 ensures that all areas of the user's surface receive massage stimulation, thereby enhancing massage comfort.

[0040] In this embodiment, adjacent massage airbags 11 are connected by air passages 10, ensuring that the air pressure inside adjacent massage airbags 11 can be adjusted synchronously. This not only simplifies the control system and makes operation convenient, but also ensures that the relative positions of adjacent massage airbags 11 remain fixed.

[0041] The structure and effect of the massage airbag 11 described in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

[0042] Example 3:

[0043] Compared to Embodiment 2, this embodiment provides a mattress.

[0044] like Figure 6The mattress shown, including the massage bag cushion 12, the limiting cushion 13 wrapping the massage bag cushion 12, and the supporting cushion 14 arranged below the massage bag cushion 12. The limiting cushion 13 plays a role of clamping positioning and protection for the massage bag cushion 12, ensuring that the massage air bags 11 on the massage bag cushion 12 are adjusted up and down by inflation and deflation in the preset position, which not only ensures that the massage bag cushion 12 can apply massage stimulation in the preset direction to improve the massage comfort, but also effectively prevents mutual interference between adjacent massage bag cushions 12. The supporting cushion 14 is used to support the massage bag cushion 12, ensuring that the vertical extension stroke generated by the massage bag cushion 12 can be converted into upward pressing force, thereby improving the massage stimulation intensity.

[0045] In this embodiment, the limiting cushion 13 is provided with perforations, the number and position of which are matched with the massage air bags 11 on the massage bag cushion 12 one by one. When installed, the limiting cushion 13 wraps the massage bag cushion 12, and the perforations are sleeved on the corresponding massage air bags 11, so that each massage air bag 11 is limited by the inner wall of the perforation, ensuring that the massage air bag 11 realizes vertical extension under the guidance of the perforation, thereby generating massage stimulation applied to the user, providing the user with a comfortable massage experience.

[0046] The structure and effect of the massage bag cushion in this embodiment are consistent with those of Embodiment Two, and will not be repeated here.
