DETAILED DESCRIPTION

[0033] The present invention is described in detail below, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] like Figures 1 to 5 As shown, the present invention provides a mattress with a graphene core through improvements. The technical solution of the present invention is as follows: the mattress with a graphene core includes a mounting frame 1 having a receiving cavity, a core body 2 mounted on the mounting frame 1, an inflatable bag device 3, a support spring 4, and a negative pressure device 50. The mounting frame 1 has a receiving cavity to form a thin-walled frame structure. Optionally, the mounting frame 1 includes an annular wall and a bottom wall. The core body 2, inflatable bag device 3, support spring 4, and negative pressure device 50 are installed through the opening of the receiving cavity.

[0035] The cushion core body 2 is fixed to the mounting frame 1 and closes the opening of the accommodating cavity. From top to bottom, the cushion core body 2 is provided with a breathable sponge layer 21, a graphene heating layer 22, a flame-retardant layer 23, a latex layer 24, and a polyester material layer 25. The graphene heating layer 22 is located below the breathable sponge layer 21. The breathable sponge layer 21 is highly comfortable, with good touch and softness. The flame-retardant layer 23 is connected to the bottom surface of the graphene heating layer 22, the top surface of the latex layer 24 is connected to the bottom surface of the flame-retardant layer 23, and the top surface of the polyester material layer 25 is connected to the bottom surface of the latex layer 24.

[0036] The graphene heating layer 22 is embedded in the mattress. In the energized state, the graphene heating layer 22 gradually separates the multi-dimensional nanocarbon in the graphene heating layer 22 as the temperature rises, wherein the nanocarbon black gradually separates from the graphene structure. As the temperature of the graphene heating layer 22 gradually rises until it reaches the preset temperature, the graphene and nanocarbon black are completely separated, and then the graphene heating layer 22 stops heating or reduces the circuit to lower the temperature, and then the graphene and nanocarbon black gradually combine together, and the cycle is repeated. During the temperature change of the graphene heating layer 22, the graphene heating layer 22 realizes the release of far infrared rays throughout the process, has good heating effect, and provides high comfort for the user during sleep.

[0037] The flame-retardant layer 23 is made of flame-retardant material to perform the heat insulation and flame-retardant effect. The flame-retardant layer 23 is arranged below the graphene heating layer 22 to effectively block the heat transfer between the graphene heating layer 22 and the air bag device 3, so that the heat is concentrated in the direction of the breathable sponge layer 21, the heat utilization rate is high, and the use safety of the mattress is high.

[0038] The latex layer 24 and the polyester material layer 25 are arranged below the flame-retardant layer 23 to further improve the shape stability and overall softness of the core body 2, and keep the user's body flat in the sleeping posture.

[0039] As shown in Figures 2 to 4 Further, the core body 2 further comprises a velvet cushion 26 detachably connected to the breathable sponge layer 21. The velvet cushion 26 is spaced apart and distributed with a plurality of arc-shaped massage protrusions 27, and the hardness of the arc-shaped massage protrusions 27 is greater than that of the velvet cushion 26. The velvet cushion 26 is of a detachable structure and has good skin-friendly warmth to facilitate the user to make independent choices. The velvet cushion 26 is fixedly attached to the breathable sponge layer 21, for example, by being directly laid and press-fitted on the breathable sponge layer 21, or by being fixedly attached to the breathable sponge layer 21 through a magic tape structure or other connection means such as buckles and buttons.

[0040] The arc-shaped massage protrusions 27 are protruding point structures on the surface of the velvet cushion 26. When the user lies flat on the core body 2, the arc-shaped massage protrusions 27 abut against the user. Alternatively, the arc-shaped massage protrusions 27 are hemispherical or conical with an arc surface. Further, a magnet is arranged in the arc-shaped massage protrusions 27. The magnet resonates with the magnetic field of the user to form a magnetic therapy effect. Alternatively, the arc-shaped massage protrusions 27 are uniformly distributed on the velvet cushion 26 to form a uniformly distributed magnetic field, and the magnetic field is consistent at any angle for the user.

[0041] In an alternative embodiment, the arc-shaped massage protrusions 27 are arranged in a mesh intersection distribution, and the distribution density of the arc-shaped massage protrusions 27 in the middle region is greater than that in the edge region. The mesh intersection distribution is that the arc-shaped massage protrusions 27 are arranged at the intersection positions of two intersecting lines on the mesh. Not every intersection needs to be arranged with the arc-shaped massage protrusions 27, and the distribution density of the arc-shaped massage protrusions 27 in the middle region is greater than that in the edge region, so that the magnetic field is relatively concentrated in the middle region and relatively dispersed in the edge region, so as to meet the application in the lying posture of the user.

[0042] In an alternative embodiment, the mounting frame 1 comprises a protective sleeve 12, a frame body 11 supported in the protective sleeve 12, and a partition plate 13 fixed in the frame body 11. The protective sleeve 12 covers the outer peripheral wall of the mounting frame 1, so that the overall touch feeling of the mounting frame 1 is comfortable, and the user is prevented from being impacted by the rigid structure of the mattress. Preferably, the protective sleeve 12 is a sleeve made of sponge material, which covers the outer peripheral wall of the frame body 11.

[0043] The frame body 11 is a frame structure, so that the overall structural form of the mounting frame 1 is basically stable. The enclosed region of the frame body 11 constitutes a receiving cavity, and the partition plate 13 is connected to the frame body 11 and divides the receiving cavity into a first space and a second space. Alternatively, the first space and the second space are separated to form independent chambers. Alternatively, the first space and the second space are partially communicated to form different air flow channels. The pad core body 2 is located in the receiving cavity and the upper surface is substantially flush with the top surface of the frame body 11.

[0044] As shown in Figures 3 to 5 , the inflatable bag device 3 is located in the receiving cavity and below the pad core body 2, and is used for adjusting the height of the pad core body 2 by inflation and deflation. The inflatable bag device 3 has an inflated state of inflation and a deflated state of flat laying, and the negative pressure device 50 provides the air pressure required for inflation of the inflatable bag device 3. In the inflated state, the pad core body 2 is raised and provides support to the pad core body 2 and the user on the mattress, so as to improve the comfort of lying.

[0045] The support spring 4 is arranged around the inflatable bag device 3, and the two ends of the support spring 4 elastically abut against the side wall of the inflatable bag device 3 and the mounting frame 1. The inflatable bag device 3 is connected to the frame body 11 through the support spring 4, so that the relative position of the inflatable bag device 3 and the mounting frame 1 is stable and will not be randomly deviated. In the inflated state, the support spring 4 outputs an elastic pre-pressure to the inflatable bag device 3, so that the inflatable bag device 3 can maintain the tendency of contraction. During the deflation process of the inflatable bag device 3, the support spring 4 further increases the exhaust pressure, so as to improve the efficiency of the inflatable bag device 3 entering the deflated state. The inflatable bag device 3 is arranged below the pad core body 2, and the support spring 4 is arranged equidistantly around the outer wall of the inflatable bag device 3, so as to improve the balance of the connection.

[0046] In an embodiment, the air bag device 3 comprises an air bag body 31 and an inflation joint assembly assembled to the air bag body 31, and the negative pressure device 50 is connected to the inflation joint assembly. The air bag body 31 is a thin-walled seal made of rubber or other materials, which is inflated and deflated through the inflation joint assembly. The support spring 4 is connected to the peripheral wall of the air bag body 31 to fix the air bag body 31 to the frame 11.

[0047] Further, the air bag body 31 is laterally provided with inwardly recessed folds 32, and the support spring 4 is connected to the folds 32. The folds 32 are distributed laterally on the air bag body 31 to facilitate the directional contraction of the air bag body 31, and the folding effect is good.

[0048] The negative pressure device 50 inflates the air bag body 31 through the inflation joint assembly, wherein the negative pressure device 50 is installed in the mounting frame 1 and communicates with the containing cavity. The negative pressure device 50 is connected to the air bag device 3 to inflate the air flow in the containing cavity into the air bag body 31. The negative pressure device 50 changes the air pressure parameters in the containing cavity, and the cushion core body 2 adjusts the temperature and humidity parameters based on the air pressure changes. Specifically, the negative pressure device 50 extracts the gas in the second space to form a negative pressure in the second space. The moisture on the surface and inside of the cushion core body 2 sinks under the action of the negative pressure, and even when the graphene heating layer 22 is in a heating state, the moisture is extracted by the negative pressure device 50, improving the dryness of the cushion core body 2 itself.

[0049] Optionally, the negative pressure device 50 comprises a suction pump 51 fixed to the mounting frame 1, an air inlet pipe 52 connected to the input end of the suction pump 51, and a three-way control valve 55 installed at the output end of the suction pump 51, the three-way control valve 55 is connected with a first air outlet pipe 53 and a second air outlet pipe 54, and the second air outlet pipe 54 is connected to the air bag device 3. The containing cavity is divided into a first space and a second space by the partition plate 13, the air inlet pipe 52 is connected to the first space, and the support spring 4 is connected to the frame 11 and located in the second space.

[0050] The negative pressure device 50 is arranged inside the mounting frame 1, and the suction pump 51 is fixed to the top surface of the partition plate 13. The input end of the suction pump 51 is installed with the air inlet pipe 52, and the bottom of the air inlet pipe 52 extends below the partition plate 13 to suck the gas in the first space. The three-way control valve 55 switches the first air outlet pipe 53 or the second air outlet pipe 54 to operate through a control instruction, wherein the second air outlet pipe 54 supplies air to the air bag device 3, and the first air outlet pipe 53 communicates with the second space to extract the gas in the second space into the first space or outside the mounting frame 1. The negative pressure device 50 can be used for two purposes, improving the application range.

[0051] As Figures 3 to 6As shown in the drawings, in an embodiment, the mattress further comprises a massage assembly 60 mounted on the mounting frame 1, the end of the massage assembly 60 alternately pushes the cushion core body 2 up and down, and the air bag device 3 is provided with a avoiding hole avoiding the expansion and contraction of the massage assembly 60. When the velvet cushion 26 is removed or laid, the massage assembly 60 is opened, and the user in a lying posture can be massaged. Among them, the cushion core body 2 is laid with the velvet cushion 26, and the massage assembly 60 pushes the user's back massage in the process of up and down combined with the arc massage convex point 27.

[0052] When the air bag device 3 is in the deflated state, the end of the massage assembly 60 pushes the lower surface of the cushion core body 2 to push the cushion core body 2 up and down, and the arc massage convex point 27 pushes the user's back massage. When the air bag device 3 is in the inflated state, the end of the massage assembly 60 is hidden in the air bag device 3 and will not exceed the cushion core body 2, and the user can lie normally. The massage assembly 60 is adjusted by the inflation and deflation of the air bag device 3 to realize the switching of the massage function and the use of space.

[0053] In an embodiment, the massage assembly 60 comprises a motor 65 mounted on the mounting frame 1, a rotating shaft 61 rotatably connected to the mounting frame 1, and a plurality of massage rods 62 distributed on the rotating shaft 61, and the end of the massage rod 62 is provided with a spherical protrusion. A plurality of rotating shafts 61 are equidistantly distributed on the mounting frame 1 and rotatably connected with the mounting frame 1. The massage rods 62 are spaced along the length direction of the rotating shaft 61, and are uniformly distributed on the circumferential outer wall at the same axial position. One end of the rotating shaft 61 is sleeved with a fixed gear 64, and the adjacent two rotating shafts 61 are connected by a transmission chain 63. One of the rotating shafts 61 is connected with the motor 65 by a transmission belt 66, so that the motor 65 drives the plurality of rotating shafts 61 to rotate synchronously.

[0054] When the user needs to massage the back, the exhaust pipe releases the gas in the air bag device 3 to make the air bag device 3 in the deflated state. The motor 65 is started to drive the rotating shaft 61 to rotate through the transmission belt 66, and the massage rod 62 alternately pushes the cushion core body 2 to rotate with the rotating shaft 61, so that the cushion core body 2 and the velvet cushion 26 can be driven without the buffering effect of the air bag device 3, and the back of the people is pressed and massaged by the arc massage convex point 27, which increases the function of the mattress.

[0055] As shown in the drawings, Figures 1 to 8 Further, an opening is formed in the outer wall of one side of the mounting frame 1, and a controller 70 is mounted on the inner wall of the opening. The model of the controller 70 is ARM9TDMI, which can control the electrical appliances inside the mattress, and is convenient for the staff to operate.

[0056] The mattress further comprises a refrigeration assembly installed on the mounting frame 1, which is communicated with the negative pressure device 50 to deliver low-temperature air flow to the movable area of the massage assembly 60. Wherein, the other side of the mounting frame 1 is provided with a rectangular slot, and the rectangular slot is hinged with a door plate 14. The refrigeration assembly is a semiconductor refrigeration sheet 16 located in the mounting slot, and the outer wall of the semiconductor refrigeration sheet 16 is installed with equidistantly distributed cooling fins 17. The semiconductor refrigeration sheet 16 can cool the air drawn into the interior of the mounting frame 1, further improving the cooling effect, and making the device more perfect and reasonable.

[0057] Further, the door plate 14 is provided with equidistantly distributed through holes 15, which can pass air into the interior of the mounting frame 1. The outer wall of the door plate 14 is clamped with a filter screen plate 18, which can filter dust in the air to prevent dust from entering the mattress core body 2, and improve the comfort of use of the mattress core body 2.

[0058] The semiconductor refrigeration sheet 16 can cool the drawn air, so that the cooled air is drawn into the mounting frame 1 and then discharged through the velvet soft cushion 26, which can blow the back of the user, thereby achieving the effect of heat dissipation, avoiding the back being hot, and improving the comfort of use of the mattress.

[0059] The above examples are only examples for clearly illustrating the present application, and are not limited to the embodiments; the scope of the present application includes but is not limited to the above examples, and any equivalent changes according to the shape and structure of the present application are included in the protection scope of the present application.
