Description

Technical Field

[0001] The invention relates to an air bag used inside a mattress, in particular to a square air bag spring and a massage mattress using the same. Background Art

[0002] Many existing massage mattresses use airbag springs to provide massage functions. These springs feature multiple coplanar massage airbags and accompanying air channels. During operation, the air channels continuously inflate and deflate the airbags, causing them to inflate locally at the center of their top surfaces, creating an upward massage stimulus. However, the massage area on the top of existing massage airbags is a small, specially designed protrusion designed to simulate a finger. This results in a small contact area, weak massage intensity, and poor massage effect. Summary of the Invention

[0003] To address the technical issues of existing airbag springs, which suffer from small massage contact area, weak massage intensity, and poor massage effects during inflation and deflation, the present invention provides a square airbag spring and a massage mattress using the same. The square airbag spring's airbags provide a large massage contact area and enhanced massage intensity during operation, significantly improving the massage effect on the body. Furthermore, a massage mattress using the square airbag spring can provide users with a more effective massage experience, with a large contact area and sufficient massage intensity at each massage point while the user lies on the mattress for a massage.

[0004] The technical solution adopted by the present invention to solve the technical problem is: a square airbag spring, including an air supply channel and multiple airbag groups distributed along its extension direction, each airbag group is provided with multiple inflatable and deflable airbags, and its characteristic is that the airbag group is composed of multiple vertically stacked square airbags connected, and the inner cavities of two adjacent square airbags are connected, the square airbags are formed by two layers of upper and lower square sheets sealed and bonded along the periphery, the surface of the square sheet corresponding to the top surface of the airbag group forms a massage part, and the inner cavity of the square airbag at the bottom of the airbag group is connected to the air supply channel. The present invention stacks a plurality of square capsules up and down and connects them to form an airbag group, and then matches an air supply channel with a plurality of airbag groups extending in the same direction to form an airbag spring with square capsules. During operation, the air supply channel inflates and deflates the square capsules of each airbag group, and the square sheet corresponding to the top surface of the airbag group inflates and bulges as a massage part, transmitting massage stimulation upward. Since the massage part is the bulged surface of the entire square sheet, the contact area for transmitting massage stimulation upward is large. The stacked multi-layer capsule combination can increase the inflation height of the airbag group and increase the vertical stroke of the massage part to increase the massage intensity. As the massage contact surface expands and the massage intensity increases, the massage effect of the airbag spring on the human body is significantly improved.

[0005] As a further improvement and supplement to the above technical solution, the present invention adopts the following technical measures: the two adjacent square bags of the airbag group are provided with matching air holes on the two adjacent layers of square sheets, and the two layers of square sheets are sealed and fitted along the edge of the hole so that the two adjacent square bags are connected and communicated with each other. An air inlet hole is provided on the square sheet corresponding to the bottom surface of each airbag group, and the air delivery channel is arranged below or on the side of the airbag group. The air delivery channel has several air outlet holes on the top wall along its extension direction, which are sealed and communicated with the air inlet holes of the corresponding airbag groups. The two adjacent square balloons in each airbag group are connected and the inner cavities are connected by partially bonding two adjacent layers of square sheets. The bonding position is to open an air transmission hole on each of the two sheets, and the two square sheets are sealed and bonded along the edge of the hole. The air transmission channel can be below or on the side of the airbag group, and through several air outlet holes opened on the top wall, they are matched one by one with the air inlet holes opened on the square sheet where the bottom surface of the corresponding airbag group is located, and sealed and connected, so that the air transmission channel can fill and discharge air for each airbag group.

[0006] The air supply channel is located below the airbag group. The top wall of the air supply channel corresponding to the air outlet is sealed and fitted with the square sheet corresponding to the corresponding air inlet along a circle around the hole edge, so that the square sheet is connected to the top wall of the air supply channel. The top wall of the air supply channel where the air outlet is located is sealed and fitted with the square sheet corresponding to the corresponding air inlet along a circle around the hole edge, so that the square sheet is fixed to the top wall of the air supply channel, thereby achieving communication between the inner cavity of the square airbag where the air inlet is located and the air supply channel. In turn, the airbag group where the square airbag is located is also connected to the top wall of the air supply channel. At the same time, the airbag group is connected to the air supply channel. Each airbag group is connected to the top wall of the air supply channel and communicates with it through the same structure.

[0007] An air delivery tube is provided below the airbag assembly, formed by two layers of stacked upper and lower strip sheets, sealed and bonded together along their circumferences. The air delivery tube is provided with an air nozzle, and the tube lumen of the air delivery tube forms the air delivery channel. The upper strip sheet has a plurality of air outlet holes along the extension direction of the air delivery tube that match the number, position, and aperture of the air inlets. At each air outlet hole position, the upper strip sheet is sealed and bonded to the square sheet corresponding to the corresponding air inlet hole along the hole rim, thereby connecting the upper strip sheet to the square sheet corresponding to each air inlet hole. The air delivery channel is the tube lumen of the air delivery tube, which is formed by two layers of stacked upper and lower strip sheets, sealed and bonded together. The upper strip sheet also has a plurality of air outlet holes corresponding to the air inlet holes of each airbag assembly. The upper strip sheet where the air outlet holes are located and the square sheet where the air inlet holes are located are sealed and bonded along the hole rims, thereby connecting the air delivery tube to each airbag assembly and communicating with each other.

[0008] The upper and / or lower strip sheets have extended edges extending outward from their respective long sides at the corresponding air outlets. When multiple square airbag springs are connected to form a matrix-arranged airbag assembly, two adjacent airbag springs are secured together by overlapping and affixing the two extended edges. Once all extended edges extending from the air outlets are overlapped and affixed, the two airbag springs are securely connected. If the extended edges are all of uniform length, adjusting the overlapping length of the two extended edges can also control the spacing between adjacent square airbag springs, ensuring a precise matrix arrangement of the airbag assembly. The extended edges correspond to the air outlets, and the connection between adjacent airbag springs matches each airbag assembly, mitigating the impact of vibration during inflation and deflation.

[0009] Positioning holes are formed on the extended edges of the sheets. The purpose of the positioning holes is to precisely control the overlap length between the extended edges of the two sheets. When the positioning holes on the extended edges of the two overlapping sheets overlap, the overlap length of the extended edges of the sheets can be kept consistent, thereby precisely defining the spacing between the two airbag springs.

[0010] The long sides of the upper strip sheet expand outward at the positions corresponding to the air outlets to form first arc segments that are concentric with and symmetrically distributed with the corresponding air outlets. The long sides of the lower strip sheet are provided with second arc segments that match the first arc segments. When the upper and lower strip sheets are sealed together, the first arc segments fit together with the matching second arc segments. The local areas of the upper strip sheet where the air outlets are located expand outward to form two symmetrical first arc segments. The purpose is to expand the local area of the upper strip sheet, ensure that there is more contact surface around the air outlets, and seal with the square sheet along the hole edge to improve the connection strength. The corresponding lower strip sheet also expands outward in the local area to form a second arc segment that matches the first arc segment. Through the corresponding fit of the first and second arc segments, the upper and lower strip sheets are sealed along the long sides of both sides.

[0011] The air supply channel is connected to the air nozzle and is closed at both ends. A drawstring for mounting the airbag spring is provided at the closed end of the air supply channel. The drawstring is provided with a detachably connected positioning structure. When the airbag spring is installed inside the mattress, the drawstring at the end is detachably connected to the positioning structure thereon for positioning within the mattress.

[0012] The drawstring is an elastic band, and the positioning structure is a Velcro or snap. The elastic band is elastic and can be elastically expanded and contracted according to installation requirements to adapt to the installation and positioning of the airbag spring. The positioning structure uses common Velcro or snaps for easy disassembly and connection.

[0013] A second object of the present invention is to provide a massage mattress comprising a mattress core layer, a control box, a surrounding pad surrounding the mattress core layer, and a comfort layer covering the mattress core layer and the surrounding pad. The mattress core layer comprises a massage airbag layer and a support layer stacked one above the other. The massage airbag layer is provided with a plurality of airbag springs, characterized in that the airbag springs are the square airbag springs described above. The plurality of square airbag springs are arranged side by side in parallel within the massage airbag layer, forming a matrix arrangement of the airbag groups. The control box is connected to the air supply channel via an air pipe. The massage airbag layer within the massage mattress uses the aforementioned square airbag springs. The massage contact area and massage intensity of the mattress during massage operation are large, the massage effect on the human body are enhanced, and the user's massage experience is better.

[0014] The beneficial technical effects of the present invention are as follows: a plurality of square capsules are stacked up and down and connected to form an airbag group, and a plurality of airbag groups extending in the same direction are matched with the same air transmission channel to form an airbag spring with square capsules. When working, the massage part on the top surface of each airbag group is the bulged surface of the entire square piece, and the contact area for transmitting massage stimulation upward is large. The stacking combination of multiple layers of capsules increases the inflation height, and then the massage part stroke becomes larger and the massage intensity increases. Under the joint effect of the expansion of the massage contact surface and the increase of the massage intensity, the massage effect of the airbag spring on the human body is significantly improved, and the massage mattress using the square airbag spring has a better massage experience.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 6 As shown, embodiment 1 is a square airbag spring, comprising an air delivery channel 1 and a plurality of airbag groups 2 distributed along its extension direction, each airbag group 2 is provided with a plurality of inflatable and deflable airbags 3, and each airbag group 2 is composed of a plurality of vertically stacked square airbags 3 connected together. As shown in the figure, this embodiment is illustrated by taking four airbag groups 2 in the figure and each airbag group having two square airbags 3 as an example, and each square airbag 3 is formed by sealing and pasting two layers of square sheets 3-1 along the periphery. The surface of the square sheet 3-1 corresponding to the top surface of the airbag group 2 forms a massage part 3-3, and the two adjacent airbag groups 2 are connected. The square capsule 3 has matching air delivery holes 3-2 on the two adjacent layers of square sheets 3-1, and the two layers of square sheets 3-1 are sealed and fitted along the edge of the holes, so that the two adjacent square capsules 3 are connected. At the same time, the inner cavities of the two adjacent capsules 3 are connected, and the inner cavity of the square capsule 3 at the bottom of the airbag group 2 is connected to the air delivery channel 1. An air inlet hole 3-4 is opened on the lower layer sheet corresponding to the bottom surface of each airbag group 2. The air delivery channel 1 is arranged below or on the side of the airbag group 2. The air delivery channel 1 has several air outlet holes 4 on the top wall along its extension direction, which are sealed and connected to the air inlet holes 3-4 of the corresponding airbag groups 2.

[0026] Because multiple square bags are stacked up and down and connected to form an airbag group, and multiple airbag groups extending in the same direction match the same air supply channel, an airbag spring with square bags is formed. When working, the air supply channel is connected to the air pump to inflate and deflate the square bags of each airbag group. The entire surface of the square sheet corresponding to the top surface of the airbag group is inflated and bulged as a massage part. The contact area for transmitting massage stimulation upward is large. The stacked multi-layer bag combination helps to increase the inflation height of the airbag group and increase the vertical stroke of the massage part, thereby improving the massage intensity. As the massage contact surface expands and the massage intensity increases, the massage effect of the airbag spring on the human body can be significantly improved.

[0027] Furthermore, the air delivery channel 1 is arranged below the airbag group 2, and the top wall of the air delivery channel 1 corresponding to the air outlet 4 is sealed and fitted with the square sheet 3-1 corresponding to the corresponding air inlet 3-4 along the edge of the hole, so that the square sheet 3-1 is connected to the top wall of the air delivery channel 1. In this embodiment, the air supply channel 1 is a lumen of an air supply tube 16. The air supply tube 16 is formed by two layers of stacked upper and lower strip sheets 5 and 6, sealed together along their peripheries. The air supply tube 16 is located below the airbag assembly 2. A nozzle 8 is provided at the end of the air supply tube 16, connecting the lumen. The upper strip sheet 5 has a plurality of air outlet holes 4 extending along the direction of the air supply tube 16, matching the number, position, and aperture of the air inlet holes 3-4. At each air outlet hole 4, the upper strip sheet 5 is sealed and attached to the square sheet 3-1 corresponding to the corresponding air inlet hole 3-4 along the periphery, connecting the upper strip sheet 5 to the square sheet 3-1 corresponding to each air inlet hole 3-4. The sheets can be made of plastic, and the connection between the two layers of sheets can be achieved by welding, which can be achieved by hot melt welding, ultrasonic welding, or other suitable bonding techniques. When the airbag spring is installed inside the mattress, the air supply tube can serve as the mounting portion for the airbag spring to contact the underlying cushioning layer.

[0028] In order to facilitate the connection between multiple square airbag springs to form an airbag group arranged in a matrix, adjacent square airbag springs can be connected through a sheet extension edge 7. The sheet connection edge 7 can be integrated with the upper strip sheet 5 and extend from the air outlet holes 4 corresponding to the long sides of the upper strip sheet 5, or be integrated with the lower strip sheet 6 and extend from the air outlet holes 4 corresponding to the long sides of the lower strip sheet 6, or both the upper and lower strip sheets have sheet extension edges 7, and positioning holes 7-1 are also provided on the sheet extension edges 7. When both the upper and lower strip sheets are provided with corresponding sheet extension edges, the two sheet extension edges on the same side of the two strip sheets are directly opposite each other and are of equal length.

[0029] In this embodiment, the sheet material extension edge 7 is preferably provided on the lower strip sheet material 6, and multiple sheet material extension edges are provided along the lower strip sheet material 6. Two adjacent airbag springs are overlapped and then fixed together by overlapping the two sheet material extension edges. After the sheet material extension edges extending from all the air outlet positions are overlapped and fitted together, the two airbag springs can be firmly connected together. When the sheet material extension edges are all of uniform length, by adjusting the overlapping length of the two extension edges, the spacing between the two adjacent square airbag springs can be further controlled, thereby ensuring the precise matrix arrangement of the airbag group. The sheet material extension edges correspond to the positions of the air outlets, and the connection positions between the two adjacent airbag springs are matched with each airbag group, which can also reduce the vibration generated by the airbag group during inflation and deflation. The overlapping and fitting between the sheet material extension edges can also be achieved by ultrasonic welding, hot melt welding, or other common technical processes.

[0030] like Figure 3 and Figure 6As shown, the long sides of the upper strip sheet 5 expand outward at the locations corresponding to the air outlet holes 4 to form first arc segments 5-1 that are concentric with and symmetrically distributed around the corresponding air outlet holes 4. Second arc segments 6-1 that match the first arc segments 5-1 are provided on the long sides of the lower strip sheet 6. When the upper and lower strip sheets 5 and 6 are sealed together, the first arc segments 5-1 and the matching second arc segments 6-1 mate. The first arc segments can expand the local area of the upper strip sheet, providing more contact surface around the air outlet holes for sealing with the square sheet along the hole edges, thereby improving the connection strength. The second arc segments match the first arc segments, ensuring a sealed fit along the long sides of the upper and lower strip sheets.

[0031] The air delivery tube 16, formed from upper and lower strips of material, is sealed at both ends. A drawstring 9 for mounting the air spring is installed at the sealed end of the air delivery channel 1. This drawstring 9 is equipped with a removable positioning structure 10. The drawstring 9 is preferably an elastic band, and the positioning structure 10 can be constructed using Velcro, snaps, zippers, or other commonly used connections in mattress production. In this embodiment, the positioning structure is preferably Velcro. When the airbag spring is installed inside the mattress, the drawstring at the end removably connects to the positioning structure above it, allowing for easy assembly and disassembly.

[0032] like Figures 7-8 As shown, Example 2 is a massage mattress comprising a mattress core layer, a control box 12, a surrounding pad 11 surrounding the mattress core layer, and a comfort layer 13 covering the mattress core layer and the surrounding pad. The mattress core layer comprises a massage airbag layer 14 and a support layer 15 stacked one above the other. The massage airbag layer 14 is equipped with several airbag springs. These airbag springs are the square airbag springs described in Example 1. These multiple square airbag springs are arranged parallel to each other within the massage airbag layer 14. This example uses five square airbag springs connected side by side as an example. Adjacent square airbag springs are connected by overlapping and affixing the extended edges 7 of the sheet material. Once all the square airbag springs are connected, all airbag groups 2 form a matrix arrangement as shown in the figure. The control box 12 is connected to the air supply path via an air tube. Furthermore, the control box's built-in air pump and controller are conventional technology.

[0033] The massage airbag layer in the massage mattress uses the aforementioned square airbag spring. When the mattress is massaging, the upward massage contact area is large and the massage intensity is enhanced, which significantly improves the massage effect on the human body and provides the user with a better massage experience.
