Description

Technical Field

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

[0002] Some massage mattresses use built-in airbag springs to inflate and deflate for massage. Common airbag springs are single-row airbag structures composed of multiple airbags arranged in a straight line. Multiple airbag springs arranged in parallel form the main structure of the mattress massage layer. The airbag spring also includes an inflatable and deflationary tracheal seat located below the row of airbags. All airbags on the same airbag spring are connected to the top wall of the tracheal seat one by one along the extension direction of the tracheal seat. The lumen of the tracheal seat forms an airway and connects to the inner cavity of the airbag. During operation, the top surface of the airbag repeatedly bulges with continuous inflation and deflation, forming an upward massage stimulation. The cross-section of this airbag spring is as follows: Figure 1 As shown, after the air tube seat 16 is inflated, the bottom wall is curved and convex. When the airbag spring is under pressure, the curved bottom wall will reduce the downward contact area of ​​the airbag spring, reduce the stability of the airbag spring support, and cause the airbag spring to swing and tilt as shown in the figure, and the airbag 2 and its top surface will also tilt accordingly. The airbag cannot normally bulge upward along the vertical direction to transmit massage stimulation, and the massage effect of the airbag spring is greatly reduced. Summary of the Invention

[0003] To address the technical issues of existing airbag springs, such as poor stability, a small downward contact area with the bottom wall of the airway seat after airway inflation, and the tendency of the airbag spring to sway and tilt, which affects the massage effect, the present invention provides a highly stable airbag spring and a massage mattress using the same. The airbag spring has a large downward contact area, high support stability, and does not sway or tilt when compressed. The airbag can transmit massage stimulation upward normally, ensuring the massage effect of the airbag spring. A massage mattress using this airbag spring has a large downward contact area when inflated and good stability when compressed, effectively ensuring the mattress's massage effect and massage experience.

[0004] The present invention solves the technical problem by adopting a technical solution: a highly stable airbag spring comprising an airway seat with a built-in airway, multiple airbags located above the airbag seat, and an air nozzle connected to the airway. The airway and the airbag seat extend in the same direction. The airbag seat is characterized in that the airbag seat has multiple airways connected at the same horizontal plane below the airbags to form the base of the airbag spring. Each airbag seat has an airway extending in the same direction, and at least one airbag seat is connected to an airbag. The multiple airbags are connected to the top wall of the corresponding airway along the extension direction of the corresponding airbag seat, and the inner cavity of the airbag is connected to the corresponding airway. The present invention combines multiple airbag seats to form the base of the airbag spring, expands the downward contact area of ​​the bottom of the airbag spring, improves the support stability of the airbag spring when under pressure, and prevents the airbag from swaying or tilting when under pressure, thereby affecting massage.

[0005] As a further improvement and supplement to the above technical solution, the present invention adopts the following technical measures: the multiple tracheal seats are spaced apart in parallel with each other, and the ends of each tracheal seat on the same side are connected together to form a common end. The airways of each tracheal seat extend to the common end to form a connection, and the air nozzle is connected to the common end to connect the airways of each tracheal seat. The tracheal seats spaced apart in parallel with each other can further improve the balance and support stability of the airbag spring when it is compressed; at the same time, the ends of each tracheal seat on the same side are connected together to form a common end, so that all tracheal seats are connected to form an integral base. The common end can be present at both ends of each bronchus, or only at one end; the air nozzle is connected to the common end to connect the airways of each tracheal seat, facilitating the synchronous inflation and deflation of each airway.

[0006] There are two tracheal seats, each extending along the direction of the airbag distribution and connecting to the airbags along the extension path. The airways of the two tracheal seats connect to the airbag lumens at the corresponding location where the tracheal seats connect to the airbags. The two tracheal seats extend below the airbags along the direction of the airbag distribution and connect to the airbags along their path, forming a double-track base below the airbags to ensure stability when the airbag springs are compressed and do not swing or tilt. At the same time, the airways of the two tracheal seats and the inner lumens of the airbags jointly participate in the inflation and deflation of the airbags, accelerating the inflation and deflation process and improving the massage effect and experience.

[0007] The two tracheal seats are symmetrically positioned below the airbag along its midline. The top walls of the two tracheal seats are respectively bonded to the left and right sides of the airbag's bottom wall. Matching through-holes are provided in the bonded top and bottom walls, connecting the airways to the airbag's internal cavity. This symmetrical arrangement ensures balanced force on the two tracheal seats when the airbag spring is compressed, further improving the spring's support stability and preventing the airbag from swaying or tilting. The top walls of the airways directly bond to the bottom wall, and communication is achieved through the openings in their respective contact surfaces.

[0008] The airbag is composed of a plurality of vertically stacked square capsules connected together. The square capsules are formed by sealing and laminating two layers of square sheets along the periphery. Adjacent square capsules are connected by opening matching ventilation holes on the two adjacent layers of square sheets and sealing and laminating them along the periphery of the ventilation holes. The plurality of square capsules are stacked up and connected to form the airbag. During operation, each square capsule is inflated and deflated repeatedly to swell upward to transmit massage stimulation. The surface of the square sheet corresponding to the top surface of the airbag swells, and the entire sheet surface can serve as the upward massage contact surface of the airbag spring, transmitting massage stimulation upward. The large massage contact surface, the plurality of square capsules stacked up and down can increase the overall inflation height of the airbag, and increase the vertical travel up and down the massage contact surface, thereby increasing the massage intensity. The expanded massage contact surface and the increased massage intensity work together to further enhance the massage effect of the airbag spring.

[0009] The tracheal seat is formed by sealingly laminating two upper and lower sheets. The upper sheet has multiple through-holes that match the air cells along the distribution direction of the air cells. The upper sheets of the two tracheal seats are integrally formed on the same upper sheet, and the lower sheets of the two tracheal seats are integrally formed on the same lower sheet. The upper and lower sheets form a common end at the joint end of the upper and lower sheets. The air nozzle is connected to the upper or lower sheet at the common end. The tracheal seat is also formed by sealingly laminating two upper and lower sheets. Through-holes that match the air cells are opened in the upper sheet along the distribution direction of the air cells. To simplify the structure and improve production efficiency, the upper sheets of the two tracheal seats are integrally formed on the same upper sheet, and the lower sheets of the two tracheal seats are also integrally formed on the same lower sheet. After the upper and lower sheets are sealed and laminating, the two tracheal seats and corresponding airways are simultaneously connected. The joint end of the two sheets forms a corresponding common end. The air nozzle is connected to the common end and can be connected to either the upper sheet or the lower sheet.

[0010] The upper and / or lower sheets are provided with extended edges extending outward from the corresponding air outlets on both long sides. These extended edges are provided with positioning holes. These extended edges facilitate the connection between airbag springs. Two adjacent airbag springs can be connected by overlapping and affixing the extended edges. The positioning holes accurately define the overlap length between the two extended edges. By aligning the positioning holes on the two extended edges, the spacing between adjacent airbag springs is defined. Changing the positioning holes' position relative to the extended edges further adjusts the spacing between adjacent airbag springs.

[0011] There are two common ends, both of which are provided with a drawstring for installation, and a detachable positioning structure is provided on the drawstring. When the airbag spring is installed inside the mattress, it can be detachably connected and positioned with the surrounding by means of the drawstring at the common end and the positioning structure thereon.

[0012] The drawstring is an elastic band, and the positioning structure is a Velcro or snap. The elastic band is flexible and can be elastically expanded and contracted according to installation requirements, adapting to the installation requirements 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 one of the aforementioned high-stability airbag springs, multiple high-stability airbag springs are arranged side by side in parallel within the massage airbag layer, so that the airbags are arranged in a matrix, and the control box is connected to the air nozzle via an air tube. The massage airbag layer within the massage mattress uses the aforementioned high-stability airbag springs, the downward contact area of ​​the bottom of the airbag spring is expanded, and the support stability of the airbag spring when under pressure is improved, thereby preventing the airbag from swaying and tilting when under pressure, affecting the massage, and ensuring the massage effect of the mattress.

[0014] The beneficial technical effects of the present invention are as follows: a plurality of air tube seats are combined to form the base of the airbag spring, thereby expanding the downward contact area of ​​the bottom of the airbag spring, improving the support stability of the airbag spring when it is under pressure, and avoiding the airbag from swinging and tilting when it is under pressure, which affects the massage; the massage mattress uses the airbag spring of the present invention, the airbag spring has stable support, the airbag will not swing and tilt when it is under pressure, and the mattress has a good massage effect and massage experience.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 2 to 7 As shown, Example 1 is an airbag spring with high stability, comprising a tracheal seat 16 with a built-in airway 1, a plurality of airbags 2 arranged above the tracheal seat 16, and an air nozzle 8 connected to the airway 1. The airway 1 and the tracheal seat 16 extend in the same direction. The tracheal seat 16 has multiple airbags 2 connected to the same horizontal plane below the airbags 2 to form the base of the airbag spring. Each tracheal seat 16 is provided with an airway 1 extending in the same direction as the corresponding tracheal seat, and at least one tracheal seat 16 is connected to the airbag 2 for inflating and deflating the airbag. The multiple airbags 2 are connected to the top wall of the corresponding airway 1 along the extension direction of the corresponding tracheal seat 16, and the inner cavity of the airbag 2 is connected to the corresponding airway 1. This embodiment is illustrated by taking two tracheal seats 16 as an example. The two tracheal seats 16 extend along the distribution direction of the airbags 2 and are connected to the airbags 2 on the extension path. The two tracheal seats 16 are spaced apart from each other in parallel. The airway 1 of each tracheal seat 16 is connected to the inner cavity of the airbag 2 at the position 2 where the corresponding tracheal seat is connected to the airbag. The two tracheal seats 16 are connected together at the ends on the same side to form a common end 17. Figure 3 In the embodiment shown, there are two common ends 17, and the air passage 1 of each tracheal seat 16 extends to the corresponding common end 17 to form a connection. The air nozzle 8 is connected to the common end 17 to connect the air passage 1 of each tracheal seat 16, and each of the two common ends 17 is connected to a air nozzle 8.

[0027] The present invention combines multiple tracheal seats to form the base of the airbag spring, thereby expanding the downward contact area of ​​the bottom of the airbag spring, improving the support stability of the airbag spring when under pressure, and preventing the airbag from swinging and tilting when under pressure, which affects massage. The two tracheal seats are both below the airbag and connected on the same horizontal plane to form the base of the airbag spring. The bottom walls of the two inflated tracheal seats form the bottom surface of the aforementioned base, expanding the downward contact area of ​​the airbag spring, improving the support stability, and allowing the airbag spring to maintain good balance when under pressure, preventing the airbag from swinging and tilting when under pressure; the tracheal seats connected to and communicating with the airbag can inflate and deflate the airbag to achieve the massage function of the airbag spring; the two common terminals are connected to air nozzles, and the two air nozzles work synchronously, which can speed up the inflation and deflation speed of the airbag spring and improve efficiency.

[0028] Furthermore, the two tracheal seats 16 are symmetrically arranged left and right along the midline of the airbag 2 below the airbag. The top walls of the air passages 1 of the two tracheal seats 16 are respectively adhered and connected to the left and right sides of the bottom wall of the airbag 2, and matching through holes 4 are respectively formed in the top wall of the air passage 1 and the bottom wall of the airbag 2 in contact, so that the air passage 1 is communicated with the inner cavity of the airbag 2. The two tracheal seats are symmetrically arranged on the left and right below the airbag. When the airbag is pressed, the two tracheal seats are stressed evenly, and the supporting stability of the airbag spring is good. The pressed airbag will not sway or tilt. The top wall of the air passage is directly adhered to the bottom wall of the airbag. Matching openings are formed on the two contact surfaces of the top wall of the air passage and the bottom wall of the airbag to realize the connection between the air passage and the airbag. In actual production, the top wall of the air passage and the bottom wall of the airbag are continuously sealed and adhered by hot pressing around the periphery of the opening.

[0029] Furthermore, the airbag 2 is composed of a plurality of square bladder bodies 3 stacked vertically. The square bladder body 3 is formed by sealing and adhering two upper and lower square sheets 3-1 along the periphery. The adjacent two square bladder bodies 3 are connected by forming matching ventilation holes 3-2 on the adjacent two layers of square sheets 3-1 and continuously sealing and adhering along the periphery of the ventilation holes. In this embodiment, the airbag is composed of two connected square bladder bodies. During operation, the two square bladder bodies of the same airbag are inflated and deflated to repeatedly bulge upward to transmit massage stimulation. The surface of the square sheet corresponding to the top surface of the airbag bulges, and the entire sheet surface serves as the massage contact surface to transmit massage stimulation upward. The massage contact surface is large. The two stacked square bladder bodies can increase the overall inflation height of the airbag, thereby increasing the vertical stroke of the massage contact surface, and the massage intensity is also increased accordingly, further improving the massage effect of the airbag spring.

[0030] Furthermore, the tracheal seat 16 is formed by sealing and adhering two upper and lower sheets. The upper sheet is provided with a plurality of through holes 4 matching the airbag 2 along the distribution direction of the airbag 2. In order to simplify the production process and improve efficiency, the upper sheets of the two tracheal seats 16 are integrally formed on the same upper sheet 5, and the lower sheets of the two tracheal seats 16 are integrally formed on the same lower sheet 6. As Figure 6 shown, the upper and lower sheets in this embodiment are both in the shape of a Chinese character "hui". The upper and lower sheets are sealed and adhered by hot pressing to form two parallel tracheal seats 16 and corresponding air passages 1. The sealing and adhering can also be achieved by other existing technical processes. The upper sheet 5 and the lower sheet 6 form the aforementioned common end 17 at the end joint. The air nozzle 8 is connected to the upper sheet 5 or the lower sheet 6 at the common end 17. As shown in the figure, in this embodiment, the air nozzle is preferably connected to the lower sheet 6.

[0031] To facilitate the connection of multiple airbag springs to form a matrix arrangement, the upper sheet 5 and / or lower sheet 6 have extended edges 7 extending outward from the corresponding through-holes 4 on both long sides. These extended edges 7 are provided with positioning holes 7-1. The two airbag springs can be secured together by overlapping and fitting the extended edges. By making the extended edges uniform in length and adjusting the fit of the extended edges, the spacing between the two airbag springs can be controlled, achieving a precise matrix arrangement of the airbags. Furthermore, the positions of the extended edges and the air outlet holes correspond, and the connection positions of the extended edges also match the individual airbags. The extended edges on both sides of the same airbag spring are perpendicular to the airbag distribution direction and symmetrically distributed on both sides, further reducing vibration during inflation and deflation. The overlapping and fitting of the extended edges can be achieved using conventional ultrasonic welding, hot press welding, or other common techniques. When both the upper and lower sheets have corresponding extended edges, the two extended edges on the same side of the two sheets are aligned vertically and aligned, and are attached together when the upper and lower sheets are joined. The positioning holes further accurately control the overlap length between the two extended edges of the sheets. As long as the positioning holes on the overlapping extended edges of the two sheets overlap, the overlap length of the two extended edges of the sheets remains consistent, thereby accurately defining the spacing between the two airbag springs. Adjusting the front-to-back position of the positioning holes on the extended edges of the sheets can further adjust the spacing between adjacent airbag springs, thereby changing the airbag distribution matrix.

[0032] like Figure 5 and Figure 6 As shown, both common ends 17 are provided with a drawstring 9 for installation, and a detachably connected positioning structure 10 is provided on the drawstring 9. Preferably, the drawstring 9 is an elastic band, and the positioning structure 10 is a Velcro or a snap button. The positioning piece structure of this embodiment adopts Velcro.

[0033] When installing the air spring inside the mattress, it can be removably connected and positioned inside the mattress using a common drawstring and the positioning structure above it. The drawstring is an elastic band that can be elastically expanded and contracted to suit installation needs, facilitating the installation of the air spring. The positioning structure uses common Velcro or snap fasteners for easy assembly and disassembly.

[0034] like Figures 8-9As 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 up and down. The massage airbag layer 14 is provided with a plurality of airbag springs. The airbag springs are the high-stability airbag springs described in Example 1. The plurality of high-stability airbag springs are arranged side by side in parallel in the massage airbag layer 14, so that the airbags 2 are arranged in a matrix. The control box 12 is connected to the air nozzle 8 via an air pipe. The built-in air pump and controller in the control box are prior art. The massage airbag layer in the massage mattress uses the high-stability airbag springs described in Example 1. The downward contact area of ​​the bottom of the airbag spring is expanded, the support stability of the airbag spring is high, the airbag will not swing or tilt when under pressure, and the massage effect and massage experience of the mattress are good.
