Description

TECHNICAL FIELD

[0001] The utility model relates to the field of bedding, in particular to a massage air bag, massage bag cushion and mattress. BACKGROUND

[0002] The existing massage air bag includes a bag body, which can be vertically telescopic to form a supporting surface on the top and middle part of the bag body, which can apply an upward pressing force. The bag body includes a top wall and a bottom wall which are vertically stacked and fixed. The top wall is formed by bending to form annular corner portions arranged along the radial direction thereof. Adjacent corner portions are connected by annular folding areas. The existing folding areas are linear along the radial cross section of the top wall. The end edges of the folding areas used to form the corner portions and the middle part across the two end edges are on the same straight line. This results in a large included angle between the corresponding end edges of adjacent folding areas, which leads to poor deformation reset performance of the corner portions. In addition, the middle part of the folding area tends to be perpendicular, which leads to a small horizontal distance between adjacent corner portions. More corner portions need to be provided to obtain a larger diameter of the bag body, which leads to a complex structure and increases the processing difficulty. SUMMARY

[0003] To solve the problems in the prior art, the utility model provides a massage air bag, massage bag cushion and mattress. The folding area is arranged in an arc shape. The included angle between the edge of the folding area and the vertical surface is smaller than the included angle between the middle part of the folding area and the vertical surface. This reduces the angle of the corner portion and increases the radial distance between adjacent corner portions. This facilitates processing and improves the user experience by reducing the number of corner portions.

[0004] The utility model realizes the following mode: a massage air bag includes a bag body. The bag body includes a top wall and a bottom wall which are vertically stacked and fixed. The top wall is formed by bending to form annular corner portions arranged along the radial direction thereof. Adjacent corner portions are connected by annular folding areas. The included angle between the edge of the folding area and the vertical surface is smaller than the included angle between the middle part of the folding area and the vertical surface to reduce the angle of the corner portion and increase the radial distance between adjacent corner portions. The folding area is arranged in an arc shape. The included angle between the edge of the folding area and the vertical surface is smaller than the included angle between the middle part of the folding area and the vertical surface. This ensures that the edge of the folding area tends to be vertical. This reduces the angle of the corner portion to improve the structural strength of the corner portion. This ensures that the corner portion can be accurately reset to improve the reset reliability. This also ensures that the middle part of the folding area tends to be horizontal to effectively increase the distance between adjacent corner portions. This facilitates processing and improves the user experience by reducing the number of corner portions.

[0005] As preferred, the top wall middle part is provided with a boss, the corner part is arranged around the boss, and the air bag is switched between the folded and stacked retracted state and the folded and vertically expanded state through inflation and deflation. The corner part is arranged around the boss to ensure that the air bag can drive the corner part to expand after inflation and guide the boss to lift upward in the vertical direction, and then press the user by the boss and form massage stimulation. The air bag is switched between the retracted state and the expanded state through inflation and deflation, and then intermittent massage stimulation is applied to the user.

[0006] As preferred, the corner part includes a lower corner and an upper corner formed by vertically repeated bending outward from the circumference of the boss, and the upper corner and the lower corner are alternately arranged and connected through the folding area. The alternately arranged upper corner and lower corner make the vertical section of the top wall circumference in the shape of W, which not only ensures that the air bag has a smaller thickness in the retracted state, but also ensures that the air bag has a larger elongation range, thereby meeting the requirement of upwardly applying a pressing force.

[0007] As preferred, the upper corners are arranged in the same height and the lower corners are arranged in the same height when the air bag is in the retracted state. The upper corners arranged in the same height can collectively support the user, and the contact area with the user is increased to reduce the foreign body sensation. The lower corners arranged in the same height can increase the contact area with the components below the massage air bag, thereby stably supporting the massage air bag, and ensuring that the boss can stretch and contract in the vertical direction.

[0008] As preferred, the upper corners and the lower corners are both acute angles when the air bag is in the retracted state. By reducing the degrees of the upper corners and the lower corners, the deformation resistance of the upper corners and the lower corners is improved, and the reset force is increased to ensure that the upper corners and the lower corners are accurately reset, preventing the massage air bag from being unable to normally stretch and contract due to irreversible deformation of the upper corners and the lower corners.

[0009] As preferred, the corresponding edges of adjacent folding areas are connected to each other and surround the corner part, and the adjacent folding areas are integrally processed and formed. The connection is sealed and reliable, and the relative positions between the corresponding edges of the adjacent folding areas are effectively maintained, thereby improving the reset reliability.

[0010] As preferred, the wall thickness of the corner part is greater than the wall thickness of the folding area. By increasing the wall thickness of the corner part, the deformation resistance of the corner part is improved, and the reset reliability is improved.

[0011] As preferred, the convex is small on top and large on bottom, and when the capsule switches to the bulging state, the convex is lifted along its axis and forms an upward massage stimulation. The top surface of the convex forms a bearing surface, which is arranged concentrically with the top wall, which not only ensures that the convex has good deformation resistance and then uses its own structural strength to convert the deformation of the capsule into a pressing force applied to the user, but also effectively reduces the area of the bearing surface, and then improves the massage stimulation intensity by concentrating the pressing force.

[0012] As preferred, the horizontal cross-sectional profile of the convex is circular, and the included angle between the end edge of the convex side wall and the vertical surface is smaller than the included angle between the middle part of the convex side wall and the vertical surface. The vertical cross-sectional profile of the convex side wall is curved, and the end edge of the convex side wall tends to be vertical, effectively improving the structural strength of the top and bottom of the convex and improving the deformation resistance. The middle part of the convex side wall tends to be horizontal, effectively increasing the diameter difference between the top and bottom of the convex, and then having the functions of stable bearing and concentrated transmission of the pressing force.

[0013] As preferred, the top edge and the bottom edge of the convex side wall have the same inclination angle, which not only facilitates processing, but also ensures that the top and bottom of the convex have balanced structural strength, meeting the requirements of stable bearing and effective transmission of the pressing force.

[0014] As preferred, the top edge of the convex side wall is vertically arranged, effectively improving the deformation resistance of the convex, and then ensuring that the bearing surface can transmit the pressing force upward, preventing the top of the convex from being deformed due to stress and increasing the bearing surface.

[0015] As preferred, the middle part of the convex side wall is an outwardly bulging curved surface, and the top edge, middle part and bottom edge of the convex side wall are connected by a rounded corner. By setting the curved surface and the rounded corner, the stress is effectively dispersed, which protects the massage air bag.

[0016] A massage capsule cushion, comprising the massage air bag, the massage air bags are arranged in a matrix, and the adjacent massage air bags are connected by air channels. The massage air bags are arranged in a matrix, which ensures that each area of the user's surface can be stimulated by massage. The adjacent massage air bags are connected by air channels, so that the air pressure in the adjacent massage air bags is adjusted synchronously, thereby controlling the massage air bags to produce synchronous massage stimulation, and improving the use experience.

[0017] A mattress, comprising the massage capsule cushion, a limiting cushion wrapping the massage capsule cushion, and a supporting cushion arranged below the massage capsule cushion. The supporting cushion is used to adjust the hardness of the mattress and effectively bear the massage capsule cushion. The massage capsule cushion provides massage stimulation to the user by stretching and deforming, effectively improving the use experience.

[0018] The utility model discloses beneficial effect: the folding area is set into cambered surface, and the included angle between folding area edge and vertical surface is less than the included angle between folding area middle part and vertical surface, both ensure that folding area edge tends to vertical, and then through the included angle of corner portion is reduced to improve its structural strength, and then ensure that corner portion can be reset accurately, improve reset reliability, also ensure that folding area middle part tends to horizontal, effectively increase the distance between adjacent corner portion, and then through reducing the number of corner portion to facilitate processing, improve use experience.

[0027] The utility model's essential characteristics are further explained below in conjunction with the drawings and specific embodiments.

[0028] Example one:

[0029] The embodiment provides a massage air bag.

[0030] As Figure 1 , 2The massage air bag shown in FIG. 3 comprises a bag body, which comprises vertically stacked top wall and bottom wall, the top wall is formed by bending to form annular corner parts along its radial direction, adjacent corner parts are connected by annular folding area 1, the edge of the folding area 1 and the vertical surface is at a smaller angle than the middle of the folding area 1 and the vertical surface, so as to reduce the angle of the corner part and increase the radial distance between adjacent corner parts. The folding area 1 is set to be arc-shaped, the edge of the folding area 1 and the vertical surface is at a smaller angle than the middle of the folding area 1 and the vertical surface, which not only ensures that the edge of the folding area 1 tends to be vertical, thereby improving the structural strength of the corner part by reducing the angle of the corner part, thereby ensuring that the corner part can be accurately reset and improving the reset reliability, but also ensures that the middle of the folding area 1 tends to be horizontal, effectively increasing the distance between adjacent corner parts, thereby facilitating processing by reducing the number of corner parts and improving the user experience.

[0031] In the embodiment, the top wall comprises a plurality of radially arranged folding areas 1, the corresponding edges of adjacent folding areas 1 are connected to form corner parts, the vertical support performance of the folding area 1 is improved by reducing the angle between the edge of the folding area 1 and the vertical surface, thereby improving the vertical support performance of the corner part by reducing the angle between the corresponding edges of adjacent folding areas 1, so as to ensure that the user can effectively support the corner part. In addition, the unfolding angle of the bag body when switching to the bulging state is increased by reducing the angle between the corresponding edges of adjacent folding areas 1, thereby increasing the reset pre-tightening force and ensuring that the bag body can be accurately reset by using the reset pre-tightening force when deflating.

[0032] In the embodiment, the top wall is provided with a boss 2, the corner parts are arranged around the boss 2, and the bag body is switched between the folded and contracted state of the folding areas 1 and the vertically unfolded bulging state. When the bag body is in the contracted state, the upper corners 3 are arranged in the same plane, the lower corners 4 are arranged in the same plane, and the folding areas 1 are all located at the same height, which not only ensures that the angle between the corresponding edges of adjacent folding areas 1 is acute, thereby improving the deformation reset reliability and improving the support performance by reducing the angle, but also effectively reduces the thickness of the bag body, thereby reducing the foreign body sensation to the user, and the flush lower corners 4 can provide stable support for the bag body, ensuring that the axis of the bag body remains in a vertical posture, thereby ensuring that the pressing force is transmitted upward. When the bag body is in the bulging state, the corner parts are unfolded and the adjacent folding areas 1 are at different heights, and the folding areas 1 have higher heights as they approach the boss 2, so as to ensure that the boss 2 can be lifted upward and apply a pressing force to the user.

[0033] In the embodiment, the corner portion comprises lower corners 4 and upper corners 3 formed by repeatedly bending the periphery of the boss 2 outward, the upper corners 3 and the lower corners 4 are arranged alternately and connected by the folding area 1. The upper corners 3 and the lower corners 4 are annular, and the upper corners 3, the lower corners 4 and the boss 2 are concentrically arranged, which ensures that each area of the periphery of the bladder has the same deformation resistance, and then ensures that each area guides the boss 2 to vertically ascend and descend along the axis of the bladder by synchronous deformation, so as to ensure that the bladder realizes telescopic deformation in a predetermined manner, and prevents the bladder from being unable to produce massage stimulation due to irreversible deformation. The distance between adjacent upper corners 3 and lower corners 4 along the radial direction of the top wall of the bladder is the same, which not only ensures that the angles of the upper corners 3 and the lower corners 4 can change synchronously when the bladder telescopes, but also ensures that the radial distance between the vertical projections of adjacent upper corners 3 and lower corners 4 remains the same, and the boss 2 is guided to ascend and descend in the vertical direction by setting balanced deformation resistance.

[0034] In the embodiment, the corresponding edges of adjacent folding areas 1 are connected to each other and form the corner portion, so that the wall thickness of the corner portion is greater than that of the folding area 1. The wall thickness is proportional to the anti-deformation performance, and the anti-deformation performance is improved by increasing the thickness of the corner portion, thereby improving the reset pre-tightening force.

[0035] In the embodiment, the boss 2 is small at the top and large at the bottom, when the bladder switches to the bulging state, the boss 2 lifts along its axis and forms upward massage stimulation. The top surface of the boss 2 forms a supporting surface, which is concentrically arranged with the top wall, which not only effectively reduces the area of the top supporting surface of the boss 2, thereby concentrating the pressing force on the user and improving the massage stimulation intensity, but also uses the structure of the boss 2 itself to obtain better resistance to deformation performance, so as to ensure that the bladder can transmit the force generated by the inflated bulging to the user's surface through the boss 2, thereby improving the force transmission efficiency.

[0036] In the embodiment, the horizontal cross-sectional profile of the boss 2 is circular, and the included angle between the side wall end edge of the boss 2 and the vertical surface is smaller than the included angle between the middle part of the side wall of the boss 2 and the vertical surface. The top edge and the bottom edge of the side wall of the boss 2 have the same inclination angle, and the top edge and the middle part of the side wall of the boss 2 have different inclination angles. The middle part of the side wall of the boss 2 is an outward bulging curved surface 5, which not only ensures that the top and bottom of the boss 2 have good anti-deformation performance, and uses the hard bottom of the boss 2 to effectively support the boss 2, and uses the hard top of the boss 2 to improve the efficiency of transmitting the pressing force, but also disperses stress by setting the boss 2 side wall with the curved surface 5, preventing local irreversible bending of the boss 2 side wall.

[0037] It can be understood that the top edge of the side wall of the boss 2 is vertically arranged, so that the top of the boss 2 has a cylindrical cavity with good vertical support performance (such as Figure 4As shown in the figure, this effectively prevents the top of the boss 2 from increasing in support surface area due to pressure deformation, and should also be considered as a specific implementation of this embodiment.

[0038] Understandably, the top edge, middle part, and bottom edge of the sidewall of the boss 2 are connected by a fillet 6 (e.g., Figure 5 As shown in the figure, it effectively disperses stress, protects the sidewalls of the boss 2, and is also convenient for processing, and should also be regarded as a specific implementation of this embodiment.

[0039] Example 2:

[0040] Compared to Embodiment 1, this embodiment provides a massage pad.

[0041] like Figure 6 The massage pad shown includes the massage airbags 7 arranged in a matrix, with adjacent airbags connected by 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.

[0042] 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.

[0043] 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.

[0044] Example 3:

[0045] Compared to Embodiment 2, this embodiment provides a mattress.

[0046] like Figure 7 The 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.

[0047] In the embodiment, the limiting pad 10 is provided with perforations, the number and position of which are matched with the massage air bags 7 on the massage bag pad 9 one by one. When installed, the limiting pad 10 wraps the massage bag pad 9, and the perforations are sleeved on the corresponding massage air bags 7, so that each massage air bag 7 is limited by the inner wall of the perforation, ensuring that the massage air bag 7 realizes vertical expansion under the guidance of the perforation, and further generates massage stimulation to the user, providing the user with a comfortable massage experience.

[0048] The structure and effects of the massage bag pad in the embodiment are consistent with those of Embodiment Two, and will not be described again.
