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 vertically expand and contract to form a support surface at the top center of the body, allowing upward pressure to be applied. The massage airbag has a truncated cone in its center, which is wider at the bottom than at the top. The top surface of the truncated cone forms an upward-facing support surface. Because the truncated cone is at the same height as the periphery of the body, its relatively small height prevents the support surface area from effectively contracting, resulting in a dispersed distribution of pressure force and affecting the intensity of the massage stimulation. Furthermore, when the massage airbag inflates and lifts the truncated cone, the top of the cone deforms under pressure, preventing the support surface from rising to the preset height. Consequently, the support surface cannot apply sufficient pressure to the user, affecting massage comfort. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a massage airbag, a massage pad, and a mattress. By increasing the height of the truncated cone, the support surface area can be effectively reduced, thus ensuring that the pressing force is concentrated and transmitted. It can also effectively increase the lifting distance of the support surface, thereby increasing the pressing force and effectively enhancing the intensity of massage stimulation.

[0004] This invention achieves its purpose through the following method: a massage airbag includes a body, the top wall of which is bent to form a truncated cone, wider at the bottom and narrower at the top. The top surface of the truncated cone forms a support surface. The truncated cone is raised upwards and positioned higher than the periphery of the top wall. By increasing the height of the truncated cone, the area of ​​the support surface is reduced, and the massage stimulation is concentrated on the massage target. Increasing the height of the truncated cone effectively reduces the area of ​​the support surface without changing the inclination angle of the side wall, thus ensuring that the pressing force is concentrated. Furthermore, by increasing the height of the support surface, the influence of the deformation of the top of the truncated cone on the lifting distance of the support surface is effectively eliminated, ensuring that the support surface is effectively lifted and increasing the pressing force, thereby effectively improving the intensity of the massage stimulation and enhancing massage comfort.

[0005] Preferably, the ratio of the height of the middle part of the bladder to the height of the periphery is A, where 1.1≤A≤1.3. This ensures that the supporting surface can reach the preset height after the bladder is inflated, thereby increasing the pressing force and improving massage comfort. It also ensures that the truncated cone shrinks downward after the bladder is deflated, ensuring that the top surface of the bladder is flat, effectively reducing the feeling of foreign objects and improving the comfort of use.

[0006] Preferably, the periphery of the top wall is circular, and the frustum and the capsule are coaxially arranged. The frustum is located in the middle of the capsule, and all areas around the capsule have the same deformation resistance, allowing the frustum to move vertically along the axis under synchronous deformation in all areas around the capsule, effectively improving deformation accuracy and ensuring that the pressing force is transmitted in the preset direction.

[0007] Preferably, the frustum sidewall is curved, and the angle between the end edge of the frustum sidewall and the vertical plane is smaller than the angle between the middle part of the frustum sidewall and the vertical plane. The curved frustum sidewall has better deformation performance, which facilitates the bending and contraction of the frustum sidewall when the bladder is deflated, thereby allowing the top of the frustum to retract into the bladder and effectively reduce the feeling of a foreign body.

[0008] Preferably, the bottom edge of the frustum extends outward and forms alternating lower and upper corners through repeated vertical bending, with adjacent upper corners connected by annular folding areas. The junction of adjacent folding areas forms a corner section, which includes upper and lower corners formed by vertical reciprocating bending of the periphery of the top wall of the capsule. This results in a W-shaped folded surface on the periphery of the top wall, comprising radially connected annular folding areas for easy telescopic folding.

[0009] Preferably, the capsule is inflated and deflated to switch between a contracted state where the folded areas are stacked and closed, and a bulging state where the folded areas are vertically expanded. The capsule can switch between a contracted state where the lower and upper corners are closed, and a bulging state where the lower and upper corners are expanded. This facilitates the vertical expansion and separation of the folded areas and ensures that the capsule switches to the bulging state. It also reduces the thickness of the capsule by vertically closing the folded areas, guiding the capsule to switch to the contracted state.

[0010] Preferably, the angle between the edge of the folding area and the vertical plane is smaller than the angle between the middle of the folding area and the vertical plane, thereby reducing the angles of the lower and upper corners. Setting the folding area in an arc shape ensures that the edge of the folding area tends to be vertical, thus improving its structural strength by reducing the angle at the corners, ensuring accurate corner repositioning and improving repositioning reliability. It also ensures that the middle of the folding area tends to be horizontal, effectively increasing the distance between adjacent corners, thus reducing the number of corners for easier processing and improved user experience.

[0011] Preferably, the capsule includes a bottom wall, and the top wall is vertically stacked and fixedly connected to the bottom wall. Both the bottom and top walls are independently processed and then stacked and welded together, which facilitates mass production, reduces processing costs, and allows for easy welding and fixing, thereby improving the capsule's sealing performance by reducing the welding area.

[0012] 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.

[0013] 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.

[0014] The beneficial effects of this utility model are as follows: By increasing the height of the frustum, the area of ​​the supporting surface can be effectively reduced without changing the inclination angle of the frustum's sidewalls, thereby ensuring that the pressing force is concentrated and transmitted. Furthermore, by increasing the height of the supporting surface, the influence of the deformation of the top of the frustum under pressure on the lifting distance of the supporting surface can be effectively eliminated, ensuring that the supporting surface is effectively lifted and the pressing force is increased, thereby effectively improving the intensity of massage stimulation and enhancing massage comfort.

[0022] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1:

[0024] This embodiment provides a massage airbag.

[0025] like Figure 1 , 2 The massage airbag shown in Figure 3 includes a body. The top wall of the body is bent to form a truncated cone 1, wider at the bottom and narrower at the top. The top surface of the truncated cone 1 forms a support surface 2. The truncated cone 1 is raised upwards and positioned higher than the periphery of the top wall. By increasing the height of the truncated cone 1, the area of ​​the support surface 2 is reduced, allowing for a more concentrated massage stimulation to be applied to the massaged object. Increasing the height of the truncated cone 1 effectively reduces the area of ​​the support surface 2 without changing the inclination angle of the sidewalls of the truncated cone 1, thus ensuring that the pressing force is concentrated. Furthermore, by raising the height of the support surface 2, the influence of the deformation of the top of the truncated cone 1 on the lifting distance of the support surface 2 is effectively eliminated, ensuring that the support surface 2 is effectively lifted and increasing the pressing force, thereby effectively increasing the intensity of the massage stimulation and improving massage comfort.

[0026] In this embodiment, the bladder switches between a contracted state (folded and collapsed) and a raised state (vertically expanded) of the folded area 6 by inflating and deflating the bladder, thereby raising and lowering the supporting surface 2 through changes in height. After the supporting surface 2 is raised, it can achieve the purpose of massage stimulation and lifting in various ways.

[0027] In this embodiment, the supporting surface 2 is set higher than the periphery of the top wall. By increasing the height of the supporting surface 2 when the bladder is in a contracted state, the supporting surface 2 has a higher position when the bladder switches from a contracted state to a raised state, thereby generating a greater pressing force to increase the intensity of massage stimulation and improve massage comfort.

[0028] In this embodiment, the increased height of the truncated cone 1 allows for a smaller supporting surface 2 while maintaining the same sidewall inclination angle. By reducing the area of ​​the supporting surface 2, the pressure applied to the user is concentrated, thereby increasing the intensity of the massage stimulation and improving massage comfort. Furthermore, due to the smaller diameter of the top of the truncated cone 1, the top of the truncated cone 1 can be concealed by deforming downwards when the bladder switches to a contracted state, ensuring that the top of the truncated cone 1 remains flush with the perimeter of the top wall. This effectively reduces the foreign body sensation experienced by the user when the bladder is in a contracted state, improving lying comfort.

[0029] In this embodiment, the ratio of the height of the middle part of the bladder to the height of the periphery is A, where 1.1 ≤ A ≤ 1.3. Preferably, A = 1.2, which ensures that the supporting surface 2 reaches the preset height after the bladder is inflated, thereby increasing the pressing force and improving massage comfort. It also ensures that the truncated cone 1 contracts downwards after the bladder is deflated, ensuring a flat top surface, effectively reducing the feeling of foreign objects and improving user comfort. Furthermore, limiting the height difference between the supporting surface 2 and the periphery of the top wall facilitates manufacturing. In addition, parameter A can also be 1.5, 1.15, 1.25, 1.3, etc., as long as it meets the requirement of 1.1 ≤ A ≤ 1.3, it should be considered a specific implementation of this embodiment.

[0030] In this embodiment, the periphery of the top wall is circular, and the frustum 1 and the bladder body are coaxially arranged. The bottom edge of the frustum 1 extends outward and forms alternating lower corners 5 and upper corners 4 through repeated vertical bending. Adjacent upper corners 4 are connected by annular folding areas 6. The periphery of the top wall has radially arranged folding areas 6, and the upper corners 4 and lower corners 5 are formed by the connection between adjacent folding areas 6, thus making the vertical cross-section of the periphery of the top wall W-shaped, which facilitates vertical expansion and contraction. Specifically, the upper corners 4 and lower corners 5 are both annular, and the upper corners 4, lower corners 5, and frustum 1 are concentrically arranged to ensure that each area of ​​the bladder body has the same deformation resistance, thereby ensuring that each area guides the frustum 1 to rise and fall vertically along the bladder body axis through synchronous deformation, ensuring that the bladder body achieves expansion and contraction deformation in a preset manner, and preventing the bladder body from failing to generate massage stimulation due to irreversible deformation. The distance between adjacent upper corner 4 and lower corner 5 along the radial direction of the top wall of the bladder is the same, which ensures that the angles of upper corner 4 and lower corner 5 can change synchronously when the bladder expands and contracts, and also ensures that the radial distance between the vertical projections of adjacent upper corner 4 and lower corner 5 remains the same. By setting balanced deformation resistance, the truncated cone 1 is guided to rise and fall in the vertical direction.

[0031] In this embodiment, the angle between the edge of the folding area 6 and the vertical plane is smaller than the angle between the middle of the folding area 6 and the vertical plane, thereby reducing the angles of the lower corner 5 and the upper corner 4. The folding area 6 is configured as a curved surface 3, with the angle between its edge and the vertical plane being smaller than the angle between the middle of the folding area 6 and the vertical plane. This ensures that the edge of the folding area 6 tends to be vertical, thereby increasing its structural strength by reducing the angle at the corners, ensuring accurate corner repositioning and improving repositioning reliability. It also ensures that the middle of the folding area 6 tends to be horizontal, effectively increasing the distance between adjacent corners, thus reducing the number of corners for easier processing and improved user experience.

[0032] In this embodiment, the capsule includes a bottom wall, and the top wall is vertically stacked and fixed to the bottom wall. The capsule includes a vertically stacked and fixed top wall and a bottom wall, both of which are integrally formed. During production, the top wall is stacked on top of the bottom wall, and the periphery of both is sealed by welding to form a pressure-adjustable and isolated capsule cavity within the capsule.

[0033] Understandably, the sidewall of the frustum 1 is a curved surface 3 (e.g., Figure 4 As shown in the figure, the angle between the end edge of the sidewall of the frustum 1 and the vertical plane is smaller than the angle between the middle part of the sidewall of the frustum 1 and the vertical plane, which should also be considered as a specific implementation of this embodiment. Specifically, the top edge and bottom edge of the sidewall of the frustum 1 have the same inclination angle, the top edge and the middle part of the sidewall of the frustum 1 have different inclination angles, and the middle part of the sidewall of the frustum 1 is an outwardly convex curved surface 3. This ensures that the top and bottom of the frustum 1 have good anti-deformation performance, effectively supports the frustum 1 with the relatively hard bottom of the frustum 1, improves the efficiency of transmitting pressing force with the relatively hard top of the frustum 1, and disperses stress by setting the sidewall of the frustum 1 with a curved surface 3, preventing the sidewall of the frustum 1 from undergoing local irreversible bending.

[0034] Example 2:

[0035] Compared to Embodiment 1, this embodiment provides a massage pad.

[0036] like Figure 5 The massage pad 9 shown includes the massage airbags 7, which are arranged in a matrix and connected to adjacent airbags 7 via air channels 8. The matrix arrangement of the massage airbags 7 ensures that all areas of the user's surface receive massage stimulation, thereby enhancing massage comfort.

[0037] In this embodiment, adjacent massage airbags 7 are connected by air passages 8, ensuring that the air pressure inside adjacent massage airbags 7 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 7 remain fixed.

[0038] 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.

[0039] Example 3:

[0040] Compared to Embodiment 2, this embodiment provides a mattress.

[0041] like Figure 6The 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 7 on the massage pad 9 are adjusted in a preset position through 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.

[0042] 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 7 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 7, so that each massage airbag 7 is limited by the inner wall of the perforation, ensuring that the massage airbag 7 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.

[0043] 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.
