Description

Technical Field

[0001] This utility model relates to air springs inside massage mattresses, and more particularly to a square air spring that inflates and deflates rapidly and a massage mattress using the same. Background Technology

[0002] Many massage mattresses currently use built-in air springs for massage. These air springs are typically single-row airbags arranged in a straight line, with multiple rows of air springs forming the massage core inside the mattress. When the air springs are working, they inflate and deflate each airbag through matching air channels. The surface of the airbag at the top of the air spring bulges, creating an upward massage stimulation. However, current air springs only have an air nozzle at one end of the air channel, resulting in slow inflation and deflation, low efficiency, and a poor massage effect. Furthermore, when a person lies on the mattress, they compress some of the airbags and the air channels beneath them. On the side of the compression point, the air channel near the air nozzle remains unobstructed, allowing normal inflation and deflation of the airbags along that section. On the other side of the compression point, the air channel away from the air nozzle is affected, preventing normal inflation and deflation of the airbags along that section. This prevents these airbags from inflating and deflation synchronously with those on the air nozzle side, significantly reducing the massage effect or even rendering the massage ineffective. During inflation, even if the airbag in the compression area gradually inflates, allowing the air delivery channel to resume inflating and deflating the airbag on the side away from the air nozzle, the inflation of the airbag on the affected side will lag significantly behind that on the side of the air nozzle. During deflation, the air delivery channel on the affected side cannot expel air in a short time, and thus the airbag matched to that section of the air delivery channel remains inflated, failing to generate continuous upward massage stimulation. Utility Model Content

[0003] To address the technical problem that existing air springs suffer from obstructed airflow on the side furthest from the air nozzle when compressed, resulting in reduced or even non-existent massage effects of some airbags, this invention provides a square airbag spring with rapid inflation and deflation, and a massage mattress using it. The airbags on both sides of the compressed area of ​​the air spring can be rapidly inflated and deflated, improving the massage effect of the air spring during inflation and deflation. The massage mattress using this air spring offers a superior massage experience.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: A square airbag spring with rapid inflation and deflation, comprising an air supply channel and a plurality of airbags arranged along its extension direction. The cavities of the airbags are connected to the air supply channel, and air nozzles are connected to the air supply channel. The key feature is that each end of the air supply channel is connected to an air nozzle, and the two air nozzles work synchronously to inflate and deflate the airbags. By connecting an air nozzle to each end of the air supply channel, the two air nozzles work in coordination to inflate and deflate the airbags, which can effectively accelerate the inflation and deflation speed of the airbags and improve the massage effect and massage experience of the air spring. Since the air supply channel is connected to air nozzles at both ends, during operation, the two air nozzles respectively cooperate with the air supply channels on both sides of the pressure position to inflate and deflate the airbags matching the air supply channels, avoiding obstruction of the air supply channel on one side due to pressure, which would prevent the airbags on the side away from the air nozzles from using this section of the air supply channel for normal inflation and deflation for massage.

[0005] As a further improvement and supplement to the above technical solution, this utility model adopts the following technical measures: the air supply channel is located below or on the side of the airbag, and is adjacent to the airbag and connects to the airbag cavity; the air nozzles at both ends of the air supply channel are sealed and connected to the top or bottom wall of the air supply channel; the air nozzle is provided with a connecting pipe extending horizontally, and the outer end of the connecting pipe is open to form the air inlet of the air nozzle. The air supply channel is located below or on the side of the airbag, and is adjacent to the airbag and connects to the airbag cavity, so as to shorten the distance between the air supply channel and the airbag and realize the rapid inflation and deflation of the airbag; the two air nozzles are sealed and connected to the top or side wall of the air supply channel to connect the air supply channel. When the air spring is connected to the inflation and deflation device, the air supply pipe extending from the inflation and deflation device is connected horizontally to the air inlet formed by the outer end of the connecting pipe, which facilitates the docking of the air supply pipe and the air nozzle.

[0006] The airbag is composed of several vertically stacked square bladders connected together. The inner cavities of adjacent square bladders are interconnected. Each square bladder is formed by sealing two layers of square sheets together around its perimeter. The surface of the square sheet corresponding to the top of the airbag forms a massage contact surface, and the inner cavity of the square bladder at the bottom of the airbag is connected to an air supply channel. Multiple square bladders are stacked vertically and connected to form an airbag. During operation, the air supply channel inflates and deflates the square bladders of each airbag. The square sheet corresponding to the top of the airbag inflates and bulges upward to transmit massage stimulation. The massage contact surface is the bulging surface of the entire square sheet, resulting in a large upward massage contact area. The combination of multiple stacked square bladders increases the overall inflation height of the airbag and increases the vertical stroke of the massage contact surface, thereby increasing the massage intensity. The expansion of the massage contact surface and the increase in massage intensity work together to enhance the massage effect of the air spring on the human body.

[0007] The airbag has two adjacent square bladders with matching air inlets on two adjacent square sheets. The two square sheets are sealed together around the edges of the inlets, connecting and communicating with the adjacent square bladders. An air inlet is located on the lower sheet corresponding to the bottom surface of the airbag. Several air outlets are formed on the top wall along the extension direction of the air supply channel, each sealing and communicating with the corresponding air inlet of the airbag. Two adjacent square bladders are partially bonded together on the two adjacent square sheets, connecting the two bladders and communicating their internal cavities. Specifically, the bonding is achieved by forming an air inlet on each of the two sheets, with the two square sheets sealed together around the edges of the inlets. The air supply channel, through several air outlets on the top wall, matches one by one with the air inlet on the lower sheet corresponding to the bottom surface of the airbag, creating a sealed communication and enabling the air supply channel to inflate and deflate each airbag.

[0008] The air supply channel is located below the airbag. The top wall of the air supply channel corresponding to the air outlet is sealed and fitted around the edge of the square sheet corresponding to the air inlet, 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 around the edge of the square sheet corresponding to the air inlet, so that the square sheet is fitted and fixed to the top wall of the air supply channel, realizing the connection between the inner cavity of the square bladder where the air inlet is located and the air supply channel. Thus, the airbag containing the square bladder is connected to the top wall of the air supply channel, and the airbag is connected to the air supply channel. All the airbags of the air spring are connected and connected to the top wall of the air supply channel through the same structure.

[0009] The air supply channel is the lumen of an air supply pipe located below the airbag. It is formed by two layers of stacked upper and lower strip-shaped sheets sealed together around the periphery. The air nozzle is connected to the upper or lower strip-shaped sheet or sandwiched between the upper and lower strip-shaped sheets. The upper strip-shaped sheet has several air outlets that match the number, position, and diameter of the air inlets along the extension direction of the air supply pipe. At each air outlet position, the upper strip-shaped sheet is sealed together with the square sheet corresponding to the air inlet around the edge of the hole, so that the upper strip-shaped sheet is connected to the square sheet corresponding to each air inlet. The air supply channel is a tube cavity located below the airbag. The air supply tube is made of two layers of stacked upper and lower strip sheets sealed together. The upper strip sheet also has several air outlets that match the air inlets on the bottom surface of each airbag. At the same time, the upper strip sheet where the air outlets are located and the square sheet where the air inlets are located are sealed together around the edge of the holes, so that the air supply tube can be connected to each airbag at the same time.

[0010] The upper and / or lower strip sheets have outwardly extending extension edges on both sides at the corresponding air outlets, with positioning holes on these extension edges. When multiple rapidly inflatable and deflated square airbag springs are connected to form a matrix arrangement of airbags, two adjacent air springs can be fixed together by overlapping the two extension edges of the sheet. After the extension edges extending from each air outlet are overlapped, the two air springs can be securely connected together. With the extension edges of the sheet being of uniform length, adjusting the overlapping length of the two extension edges can control the spacing between two adjacent rapidly inflatable and deflated square airbag springs, ensuring a precise matrix arrangement of the airbags. The positions of the sheet extension edges and the air outlets correspond, and the connection positions between adjacent air springs match each airbag, reducing the impact of vibration generated during the inflation and deflation of the airbags. The overlapping and bonding between the two sheet extension edges can be achieved using common existing technologies such as ultrasonic welding, thermofusion welding, or other common techniques. When both the upper and lower strip sheets have corresponding sheet extension edges, the two sheet extension edges on the same side of the two strip sheets are of equal length and directly opposite each other. The function of the positioning holes is to precisely control the overlap length between the two sheet extension edges. As long as the positioning holes on the two overlapping sheet extension edges coincide, the overlap length of the sheet extension edges can be kept uniform, thereby precisely controlling the spacing between the two air springs.

[0011] The air supply pipe has pull straps at both ends for installing air springs, and the pull straps have detachable positioning structures. When the air springs are installed inside the mattress, they can be detachably connected and positioned with the surrounding area by means of the pull straps at the ends and the positioning structures thereon.

[0012] The pull strap is an elastic band, and the positioning structure is Velcro or snap fasteners. The elastic band is flexible and can stretch and contract as needed for installation, adapting to the installation and positioning of air springs. The positioning structure uses common Velcro or snap fasteners for easy assembly and disassembly.

[0013] The second objective of this utility model is to provide a massage mattress, comprising a mattress core layer, a control box, a surrounding padding around the mattress core layer, and a comfort layer covering the mattress core layer and the surrounding padding. The mattress core layer includes stacked massage airbag layers and a support layer. The massage airbag layers contain several airbag springs, characterized in that the air springs are the aforementioned fast-inflation and deflation square airbag springs. Multiple fast-inflation and deflation square airbag springs are arranged parallel to each other within the massage airbag layer, forming a matrix arrangement of the airbags. The control box is connected to air nozzles at both ends of the air supply channel via air tubes. The massage airbag layer within the massage mattress uses the aforementioned fast-inflation and deflation square airbag springs, resulting in rapid and efficient airbag inflation and deflation. Airbags on both sides of the mattress under pressure can be quickly inflated and deflated, ensuring a normal massage experience and preventing airbags in certain areas from being unable to deflate due to pressure, thus affecting the massage. Furthermore, the airbags are composed of stacked square bladders, resulting in a large massage contact area and high massage intensity during operation.

[0014] The beneficial technical effects of this utility model are as follows: By connecting air nozzles to both ends of the air supply channel and allowing the two air nozzles to work synchronously to inflate and deflate the airbag, the inflation and deflation speed of the airbag is accelerated, improving the massage effect and massage experience of the air spring. No matter where the person presses on the air spring, it can be ensured that at least one air nozzle can inflate and deflate the airbag. When the person presses on any position between the two air nozzles, the two air nozzles cooperate with the air supply channels on both sides of the pressed position to inflate and deflate the airbags matched by their respective air supply channels. This avoids the situation where the air supply channel on the pressed position side is blocked, causing the airbags on the side away from the air nozzle to be unable to use this section of the air supply channel for inflation and deflation to perform massage work.

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

[0025] like Figures 1-6 As shown, Embodiment 1 is a square airbag spring for rapid inflation and deflation, including an air supply channel and a plurality of airbags 2 arranged along its extension direction. The cavities of the airbags 2 are connected to the air supply channel. An air nozzle 8 is connected to the air supply channel. An air nozzle 8 is connected to each end of the air supply channel. The two air nozzles 8 work synchronously to inflate and deflate the airbags 2. The air supply channel can be located below or on the side of the airbags 2 and is close to the airbags 2 and connects to the cavities. The air nozzles 8 at both ends of the air supply channel are sealed to the top or bottom wall of the air supply channel. The air nozzles 8 are provided with a connecting pipe extending in the horizontal direction. The outer end of the connecting pipe is open to form the air inlet of the air nozzle 8.

[0026] Because both ends of the air supply channel are connected to air nozzles, and the two nozzles work together synchronously to inflate and deflate the airbag, the inflation and deflation speed of the airbag can be effectively accelerated, improving the massage effect and experience of the air spring. Since the air supply channel has air nozzles at both ends, during operation, the two nozzles cooperate with the air supply channels on both sides of the pressure position to inflate and deflate the airbags corresponding to those channels. This avoids the situation where, with a single nozzle, if the air supply channel on the pressure position side is blocked, the airbag on the side furthest from the nozzle cannot use the blocked portion of the air supply channel for inflation and deflation, thus affecting the massage. When connecting the square airbag spring to the inflation / deflation device, the air supply pipe extending from the inflation / deflation device is connected horizontally to the air inlet formed by the open end of the connecting pipe, facilitating the connection of the air supply pipe and the air nozzle.

[0027] Furthermore, the airbag 2 is composed of several vertically stacked square bladders 3 connected together, with the inner cavities of two adjacent square bladders 3 connected. The square bladder 3 is formed by sealing and bonding two layers of square sheets 3-1 around its perimeter. The surface of the square sheet 3-1 corresponding to the top surface of the airbag 2 forms a massage part 3-3. The inner cavity of the square bladder 3 at the bottom of the airbag 2 is connected to the air supply channel 1. Two adjacent square bladders 3 on the airbag 2 have matching air supply holes 3-2 on the adjacent two layers of square sheets 3-1. The two layers of square sheets 3-1 are sealed and bonded around the edge of the holes, so that the two adjacent square bladders 3 are connected and communicate with each other. The lower sheet corresponding to the bottom surface of the airbag 2 has an air inlet hole 3-4. The air supply channel 1 has several air outlet holes 4 on its top wall along its extension direction, which are respectively sealed and connected to the air inlet holes 3-4 of the corresponding airbag 2.

[0028] During operation, the air supply channel inflates and deflates the square bladders of each airbag. The square sheet surface corresponding to the top of the airbag inflates and becomes a massage contact surface, transmitting massage stimulation upwards. The massage contact area is large, and the combination of multiple stacked square bladders can also increase the overall inflation height of the airbag and increase the vertical stroke of the massage contact surface, thereby increasing the massage intensity. With the combined effect of the expanded massage contact area and the increased massage intensity, the square airbag spring pair provides a better massage effect.

[0029] Furthermore, below the airbag 2, an air supply pipe 16 is provided, consisting of two stacked upper strip-shaped sheets 5 and lower strip-shaped sheets 6 sealed around their periphery. The cavity of the air supply pipe 16 serves as the aforementioned air supply channel 1. The top wall of the air supply channel 1, where the air outlet 4 is located, i.e., the upper strip-shaped sheet 5, is sealed around the periphery of the square sheet 3-1 where the corresponding air inlet 3-4 is located, so that the square sheet 3-1 is connected to the top wall of the air supply channel 1, i.e., the upper strip-shaped sheet 5. In this embodiment, the upper strip-shaped sheet 5 has several air outlets 4 along the extension direction of the air supply pipe 16, which match the number, position, and diameter of the air inlet 3-4. The upper strip-shaped sheet 5 is sealed around the periphery of the square sheet 3-1 corresponding to the corresponding air inlet 3-4 at each air outlet 4 position, so that the upper strip-shaped sheet 5 is connected to the square sheet 3-1 corresponding to each air inlet 3-4, thereby connecting all airbags to the air supply channel. The air nozzle 8 can be connected to the upper strip sheet 5 or the lower strip sheet 6, or sandwiched between the upper and lower strip sheets. In this embodiment, it is preferred that the air nozzle 8 is connected to the lower strip sheet 6.

[0030] To facilitate the connection between multiple square airbag springs and arrange the airbags in a matrix, adjacent square airbag springs can be connected by the sheet extension edge 7. The sheet connection edge 7 can be integral with the upper strip sheet 5 and extend from the air holes 4 corresponding to its two long sides, or integral with the lower strip sheet 6 and extend from the air holes 4 corresponding to its two long sides, or both the upper and lower strip sheets have sheet extension edges 7. At the same time, the sheet extension edge 7 also has positioning holes 7-1. When both the upper and lower strip sheets have corresponding sheet extension edges, the two sheet extension edges on the same side of the two strip sheets are vertically aligned and of equal length.

[0031] In this embodiment, the sheet extension edge 7 is preferably located on the lower strip sheet 6, and multiple sheet extension edges are provided along the lower strip sheet 6. Two adjacent airbag springs are fixed together by overlapping and bonding the two sheet extension edges. Once the sheet extension edges to be matched are overlapped and bonded, the two airbag springs can be stably connected together. With the sheet extension edges of uniform length, adjusting the overlap length of the two extension edges can further control the spacing between two adjacent square airbag springs, thereby ensuring a precise matrix arrangement of the airbags. The positions of the sheet extension edges and the air outlets correspond, and the connection positions between two adjacent airbag springs correspond to the airbags, which can reduce the impact of vibration generated during the inflation and deflation of the airbags. The overlap and bonding between the sheet extension edges can also be achieved by ultrasonic welding, hot melt welding, or other common technical processes.

[0032] like Figure 3 and Figure 6As shown, the long sides of the upper strip sheet 5 extend outwards at the positions corresponding to each air outlet 4 to form a first arc segment 5-1 that is concentric and symmetrically distributed with respect to the corresponding air outlet 4. The long sides of the lower strip sheet 6 are provided with a second arc segment 6-1 that matches the first arc segment 5-1. When the upper strip sheet 5 and the lower strip sheet 6 are sealed together, the first arc segment 5-1 and the matching second arc segment 6-1 are in contact. The first arc segment can increase the local area of ​​the upper strip sheet, allowing more contact surface around the air outlets to seal against the square sheet along the edge of the holes, thus improving the connection strength. The matching of the second arc segment and the first arc segment ensures a sealed fit between the upper and lower strip sheets along their long sides.

[0033] The air supply pipe 16, formed by bonding upper and lower strip-shaped sheets, is closed at both ends. At each of the closed ends of the air supply channel 1, a pull strap 9 for installing the air spring is provided. The pull strap 9 has a positioning structure 10 for detachable connection. The pull strap 9 is preferably an elastic band, and the positioning structure 10 can be Velcro, snaps, zippers, or other connections commonly used in mattress manufacturing. In this embodiment, the positioning structure is preferably Velcro. When the square air spring described in this embodiment is installed inside the mattress, it is detachably connected and positioned within the mattress by the pull straps at both ends and the positioning structure thereon. The Velcro facilitates easy assembly and disassembly.

[0034] like Figures 7-8 As shown, Embodiment 2 is a massage mattress, including a mattress core layer, a control box 12, a surrounding pad 11 around the mattress core layer, and a comfort layer 13 covering the mattress core layer and the surrounding pad. The mattress core layer includes an upper and lower stacked massage airbag layer 14 and a support layer 15. The massage airbag layer 14 contains several airbag springs, which are the rapidly inflatable and deflated square airbag springs described in Embodiment 1. The multiple rapidly inflatable and deflated square airbag springs are arranged side by side in parallel within the massage airbag layer 14, so that the airbags 2 are arranged in a matrix. The control box 12 is connected to the air nozzles 8 at both ends of the air supply channel 1 through an air tube. The built-in air pump and controller in the control box are existing technologies.

[0035] The massage mattress uses the aforementioned fast-inflation and deflation square airbag springs. The airbags inflate and deflate quickly and efficiently, and the airbags on both sides of the mattress under pressure can inflate and deflate quickly to ensure a normal massage experience and prevent localized airbags from being unable to release air due to pressure, thus affecting the massage. Furthermore, the airbags are composed of stacked square bladders, which increases the massage contact area during operation and can also improve the massage intensity.
