[0032] Combination Figure 1 and Figure 2 According to the utility model, the air mattress includes: a mattress 110, which can be inflated to prevent bedridden patients from forming bedsores, and to prevent patients from having blood flow disorders and numbness of hands and feet.

[0033] Furthermore, the air mattress also includes an outer cover assembly 120, which includes: a first cover body 121, the first cover body 121 is provided with a plurality of first zipper portions 1211, and the plurality of first zipper portions 1211 are arranged sequentially in the circumferential direction of the first cover body 121; a second cover body 122, the second cover body 122 is provided with a plurality of second zipper portions 1221, and the plurality of second zipper portions 1221 are arranged sequentially in the circumferential direction of the second cover body 122, and are respectively arranged one by one corresponding to the plurality of first zipper portions 1211, and the first cover body 121 and the second cover body 122 are respectively covered on both sides of the mattress 110 in the thickness direction.

[0034] Specifically, the corresponding first zipper portion 1211 and the second zipper portion 1221 can be selectively connected, so that the first cover body 121 and the second cover body 122 can be separated or connected through the first zipper portion 1211 and the second zipper portion 1221. By arranging multiple first zipper portions 1211 in sequence in the circumferential direction of the first cover body 121 and arranging multiple second zipper portions 1221 in sequence in the circumferential direction of the second cover body 122, the first cover body 121 and the second cover body 122 can be selectively separated at different positions in the circumferential direction, which is convenient for staff to check the position of the air leakage of the mattress 110 and improve the maintenance convenience of the air mattress.

[0035] In the related art, when the air mattress has a leakage problem, the first cover body and the second cover body need to be separated as a whole, which greatly increases the difficulty of repairing the air mattress and is not easy to operate, resulting in poor maintenance convenience of the air mattress.

[0036] The present application arranges a plurality of first zipper portions 1211 in the circumferential direction of the first cover body 121 and a plurality of second zipper portions 1221 in the circumferential direction of the second cover body 122, and the plurality of first zipper portions 1211 and the plurality of second zipper portions 1221 are arranged in one-to-one correspondence, so as to facilitate the selective separation of the connected positions of the first cover body 121 and the second cover body 122 in the circumferential direction, so as to facilitate the inspection and maintenance of the mattress 110, without separating the first cover body 121 and the second cover body 122 as a whole, so that the inspection and maintenance of the mattress 110 can be targeted, the difficulty of operation and inspection and maintenance is reduced, and it is beneficial to improve the inspection and maintenance efficiency of the mattress 110.

[0037] According to the air mattress of the utility model, a plurality of first zipper portions 1211 and second zipper portions 1221 that can be connected one by one are arranged between the first cover body 121 and the second cover body 122, so that the first zipper portion 1211 and the second zipper portion 1221 correspondingly close to the air leakage position can be selected according to the different air leakage positions of the mattress 110, so that the outer cover assembly 120 can be selectively opened at different positions according to the different air leakage positions of the mattress 110, so as to facilitate the maintenance of the mattress 110, and the maintenance of the mattress 110 can be targeted, reducing the difficulty of operation and maintenance, which is conducive to improving the maintenance efficiency of the mattress 110.

[0038] In some embodiments of the present invention, the same group of first zipper portion 1211 and second zipper portion 1221 are joined by a pull head 123, and the pull head 123 can move along the extension direction of the first zipper portion 1211 and the second zipper portion 1221, so that the first zipper portion 1211 and the second zipper portion 1221 can be docked or opened.

[0039] For example, when the outer cover assembly 120 needs to be closed, the driving pull head 123 is moved along the first direction between the first zipper portion 1211 and the second zipper portion 1221, and the first zipper portion 1211 and the second zipper portion 1221 are docked, so that the first cover body 121 and the second cover body 122 are connected and in a closed state; when the outer cover assembly 120 needs to be opened, the driving pull head 123 is moved along the second direction between the first zipper portion 1211 and the second zipper portion 1221, and the first zipper portion 1211 and the second zipper portion 1221 are undocking, so that the first cover body 121 and the second cover body 122 are opened, and the staff can inspect the mattress 110 through the opened position between the first cover body 121 and the second cover body 122.

[0040] It should be noted that the first direction and the second direction are opposite, and the "first direction" refers to the moving direction of the slider 123 that switches the first zipper portion 1211 and the second zipper portion 1221 from the open state to the docking state, and the "second direction" refers to the moving direction of the slider 123 that switches the first zipper portion 1211 and the second zipper portion 1221 from the docking state to the undocking state.

[0041] like Figure 1 As shown, in some embodiments of the present invention, the same group of first zipper portion 1211 and second zipper portion 1221 are joined by two sliders 123 to pull the first zipper portion 1211 and the second zipper portion 1221 apart in both directions, thereby improving the efficiency of opening or closing the outer cover assembly 120, which is further beneficial to improving the maintenance efficiency of the mattress 110.

[0042] Among them, the two sliders 123 can move toward or away from each other. When the two sliders 123 move in directions away from each other, the first zipper portion 1211 and the second zipper portion 1221 are pulled apart in both directions. When the two sliders 123 move in a direction approaching each other, the first zipper portion 1211 and the second zipper portion 1221 engage and cooperate, thereby closing the first zipper portion 1211 and the second zipper portion 1221.

[0043] Combination Figure 1 and Figure 2 In some embodiments of the utility model, in the projection in the thickness direction, the projection of the mattress 110 is rectangular; wherein, one end of the first zipper portion 1211 is arranged in the middle of the long side of the rectangle, and the other end of the first zipper portion 1211 is arranged in the middle of the wide side of the rectangle; one end of the second zipper portion 1221 is arranged in the middle of the long side of the rectangle, and the other end of the second zipper portion 1221 is arranged in the middle of the wide side of the rectangle.

[0044] Specifically, the first zipper portion 1211 is located at a vertex position of the rectangle, and the first zipper portion 1211 extends from the middle position of the long side of the rectangle to the middle position of the wide side adjacent to the long side. Similarly, the second zipper portion 1221 corresponding to the first zipper portion 1211 extends from the middle position of the long side of the rectangle to the middle position of the wide side adjacent to the long side.

[0045] Furthermore, four first zipper portions 1211 may be provided, each of which is located at a vertex position of the rectangle. Accordingly, four second zipper portions 1221 may be provided, each of which is arranged opposite to the first zipper portion 1211 in the thickness direction.

[0046] Therefore, when the mattress 110 leaks, the first zipper portion 1211 and the second zipper portion 1221 close to the leaking position can be opened accordingly according to the leaking position of the mattress 110 to inspect the mattress 110 without separating the first cover body 121 and the second cover body 122 as a whole, thereby effectively improving the inspection efficiency of the mattress 110.

[0047] Combination Figure 2 and Figure 3 In some embodiments of the present invention, the mattress 110 is provided with a plurality of air bags 111 , and the plurality of air bags 111 are arranged in sequence along the length direction of the mattress 110 .

[0048] Specifically, the airbag 111 is used for inflation, and after being inflated, the airbag 111 can expand, so that the air mattress can be inflated.

[0049] Among them, multiple air bags 111 can be inflated simultaneously or some of the air bags 111 can be selectively inflated to adjust the fullness of the mattress 110 and the local fullness, so that the mattress 110 can adapt to the force requirements of different parts of the patient, which is conducive to dispersing the pressure of the patient's body, reducing friction and damage to the skin, and preventing the patient from forming bedsores.

[0050] Combination Figure 1 and Figure 2 In some embodiments of the utility model, the air mattress further includes: an air supply pipe 130, the air supply pipe 130 is provided with a plurality of first inflation branches 131, and the plurality of first inflation branches 131 are respectively connected one by one with the plurality of air bags 111; an inflation and exhaust device 140, the inflation and exhaust device 140 is connected to the air supply pipe 130, and is suitable for supplying air to the air supply pipe 130, and the air supply pipe 130 is suitable for exhausting air through the inflation and exhaust device 140.

[0051] Specifically, the inflation and exhaust device 140 includes an air compressor and a control valve. Control valves are provided on multiple first inflation branches 131. The air compressor is connected to the air supply pipe 130 and can supply air to the air supply pipe 130. The gas flows in the air supply pipe 130 to the multiple first inflation branches 131, and further flows into the airbag 111 through the first inflation branch 131, so that the inflation and exhaust device 140 can inflate the airbag 111.

[0052] Among them, the control valve can realize two-way flow of gas, that is, the gas in the airbag 111 can also be discharged in sequence through the first inflation branch pipe 131, the air supply pipe 130 and the inflation and exhaust device 140, so that the airbag 111 can have an inflated state and a deflated state, which is convenient for adjusting the fullness of the mattress 110 and is conducive to realizing different working modes of the mattress 110.

[0053] In some embodiments of the present invention, multiple air bags 111 are divided into three groups arranged along the length direction of the mattress 110. When the inflation and exhaust device 140 inflates two of the three groups of air bags 111, the other group of the three groups of air bags 111 is exhausted through the exhaust device.

[0054] For example, 10 airbags 111 may be provided, and the 10 airbags 111 are arranged in sequence in the length direction of the mattress 110, wherein the 1st, 5th, and 9th airbags 111 constitute a first group of airbags 111, the 2nd, 4th, 6th, 8th, and 10th airbags 111 constitute a second group of airbags 111, and the 3rd and 7th airbags 111 constitute a third group of airbags 111. When the inflation and exhaust device 140 inflates the first group of airbags 111 and the third group of airbags 111 through the air delivery pipe 130 and the first inflation branch pipe 131, When the first group of air bags 111 and the third group of air bags 111 are inflated, the gas in the second group of air bags 111 can be discharged outwardly through the first inflation branch pipe 131, the air supply pipe 130 and the inflation and exhaust device 140, so that the second group of air bags 111 is in an exhausted state. By alternately exhausting and inflating the three groups of air bags 111, the three groups of air bags 111 alternately expand and contract, so that different positions of the mattress 110 can alternately rise and fall, thereby realizing the function of massaging the patient and preventing the occurrence of bedsores.

[0055] Among them, making two of the three groups of air bags 111 in an inflated state and the other group in an exhausted state can also effectively reduce the concave area of ​​the mattress 110, increase the area of ​​the mattress 110 supporting the patient, and help reduce the local bearing pressure of the human body, making the mattress 110 rise and fall gently, and improving the patient's user experience.

[0056] Combination Figure 2 and Figure 3In some embodiments of the present invention, a power plug 160 is connected to the inflation and exhaust device 140, and the power plug 160 is used to be electrically connected to a power source so that the inflation and exhaust device 140 can be powered on and work.

[0057] like Figure 2 As shown, in some embodiments of the utility model, the air mattress also includes: a CPC joint assembly 150, the CPC joint assembly 150 includes a first joint (not shown) and a second joint (not shown), one of the first joint and the second joint is arranged on the air supply pipe 130, and the other of the first joint and the second joint is arranged on the inflation and exhaust device 140, and the inflation and exhaust device 140 and the air supply pipe 130 are suitable for being detachably connected via the CPC joint assembly 150 (externally threaded joint assembly).

[0058] For example, the air pipe 130 may be provided with a first joint, and the inflation and exhaust device 140 may be provided with a second joint. The first joint and the second joint may be detachably connected and matched, so that the inflation and exhaust device 140 and the air pipe 130 may be detachably connected via the CPC joint assembly 150. By providing the CPC joint assembly 150, the connection reliability between the inflation and exhaust device 140 and the air pipe 130 is ensured, and the air pipe 130 and the inflation and exhaust device 140 are effectively prevented from being separated, so as to avoid the inflation and exhaust device 140 and the air pipe 130 being separated due to accidental touch when the staff performs operations such as changing the sheets of the air mattress, and the CPC joint assembly 150 is provided. A connecting structure is formed on the head assembly 150, so that while ensuring the reliability of the connection between the air pipe 130 and the inflation and exhaust device 140, no external connecting head is required, which is beneficial to reducing the risk of air leakage between the inflation and exhaust device 140 and the air pipe 130. The CPC joint assembly 150 has the characteristics of automatic locking, confirming the safe connection with sound, easy one-handed operation, and applicability to different fluid media, so as to facilitate the connection between the inflation and exhaust device 140 and the air pipe 130 and the separation of the inflation and exhaust device 140 from the air pipe 130. In addition, the CPC joint assembly 150 is small in size and light in weight, so that the layout space required is small, so that it can be installed in a small space.

[0059] Among them, the CPC connector assembly 150 has various forms of connecting structures, for example: American thread NPT (NPT refers to the American standard 60-degree tapered pipe thread), British oblique thread BSPT (BSPT refers to the British tapered pipe thread standard, which means that the thread angle is 55 degrees and the thread has a taper of 1:16), British straight thread BSPP (BSPP refers to the British cylindrical pipe thread standard, only internal threads), pagoda-type hose barb (hose barb refers to quick connector), ferrule-type compression with ferrule (compression with ferrule refers to ferrule compression) and flare type for the semiconductor industry (flare type refers to the flare tube connection type), etc. It can be understood that the construction of the connecting structure on the specific CPC connector assembly 150 can be determined according to the actual assembly requirements, and no specific limitation is made here.

[0060] In addition, the CPC connector assembly 150 has a variety of different sizes of diameters to meet different flow requirements, and can be connected to pipes of different materials and sizes, including PVC (polyvinyl chloride) pipes, PE (polyethylene) pipes, PU (polyurethane) pipes, PP (polypropylene) pipes, nylon pipes, silicone pipes, fluoropolymer pipes, brass pipes, etc. The inner diameter of the pipe is 1 / 16 inch to 1 inch to adapt to different air mattresses, and the CPC connector assembly 150 can choose a variety of different materials of sealing rings and can meet the chemical compatibility requirements of different processed fluids. It has a variety of installation modes, including pipe-to-pipe type, right-angle type, panel type, male thread and female thread, etc., to meet the different usage needs of users.

[0062] Therefore, the CPC joint assembly 150 can be adapted to air mattresses of different specifications, and there is no need to design a connecting device according to the different specifications and models of the air mattresses, which is conducive to improving the production convenience of the air mattresses.

[0063] Of course, it is understandable that the second joint can be set on the gas pipe 130, and the first joint can be set on the inflation and exhaust device 140. The specific setting positions of the first joint and the second joint can be determined according to actual production requirements and are not specifically limited here.

[0064] like Figure 2 As shown, in some embodiments of the utility model, an inflation space 1111 is formed in the airbag 111, and the first inflation branch 131 is suitable for conveying gas into the inflation space 1111; a built-in airbag 112 is provided in the inflation space 1111, and the built-in airbag 112 forms an inflation cavity 1121 independent of the inflation space 1111.

[0065] Specifically, the first inflation branch 131 is connected to the inflation space 1111, and the inflation and exhaust device 140 can inflate air into the inflation space 1111 through the air supply pipe 130 and the first inflation branch 131, so that the airbag 111 expands, and the built-in airbag 112 is arranged in the inflation space 1111. The inflation cavity 1121 can be filled with gas to put the built-in airbag 112 in an expanded state, and the inflation cavity 1121 is not connected to the inflation space 1111 or the first inflation branch 131 to prevent the built-in airbag 112 from leaking when air leakage occurs between the airbag 111 and the first inflation branch 131. Even if the airbag 111 leaks, the built-in airbag 112 can still be in an expanded state and support the patient, preventing the patient from contacting the hard bed board or bed frame, thereby effectively ensuring the patient's comfort.

[0066] In some embodiments of the utility model, a second inflation branch pipe (not shown) is provided on the gas supply pipe 130 , the second inflation branch pipe and the first inflation branch pipe 131 are respectively connected to the gas supply pipe 130 , and the second inflation branch pipe is used to deliver air into the inflation cavity 1121 .
