Description

Technical Field

[0001] The utility model relates to the field of inflatable products, and more specifically, to an inflatable bed with multiple layers and chambers. Background Art

[0002] An inflatable mattress is a mattress that has strong flexibility and elasticity and expands in volume after being inflated. An inflatable mattress can achieve a close combination of the bed and the human body, so that the cervical spine, lumbar spine, legs and wrists are no longer suspended in the air, and can help the human body eliminate fatigue as soon as possible. At the same time, it is also very easy to carry. When folded, it is only the size of a pillow. When not in use, it can be folded and placed in a locker. When needed, it can be taken out and inflated. Due to its portability and small footprint, it can be placed indoors and outdoors at will, getting rid of the defects of traditional furniture that is bulky and occupies a large area. People can use it when working outside, moving frequently, camping in the wild, swimming, accompanying or taking a temporary break at work. Due to its wide application, people's demand for inflatable mattresses is growing.

[0003] However, existing inflatable beds usually just lay fabrics flat to form a top layer, and the overall softness of the mattress is completely dependent on the cavity inside the mattress body, resulting in limited comfort and poor user experience. Utility Model Content

[0004] The utility model aims to overcome at least one defect (shortcoming) of the above-mentioned prior art and provide an inflatable bed with multiple chambers for improving the comfort of the inflatable bed.

[0005] The technical solution adopted by the utility model is a multi-chamber inflatable bed, including a mattress body formed by a top layer, a surrounding belt and a bottom layer, the top layer includes a first surface layer and a second surface layer arranged under the first surface layer, the first surface layer and / or the second surface layer are connected to the surrounding belt; the first surface layer and the second surface layer are connected to form a plurality of surface side chambers.

[0006] In the present technical solution, the top layer is a layer supporting the human body, the surrounding belt forms the side of the inflatable bed, and the bottom layer is a layer in contact with the ground. The first surface layer is a layer in direct contact with the human body, and the first surface layer and / or the second surface layer are welded and connected to the surrounding belt. The first surface layer and the second surface layer are also welded and connected. For example, the first surface layer is connected to the surrounding belt, and the second surface layer is connected to the first surface layer; or the second surface layer is connected to the surrounding belt, and the first surface layer is connected to the second surface layer. The connecting line connecting the first surface layer and the second surface layer forms the edge of the face side chamber. The face side chamber forms a plurality of elastic protrusions on the top layer, which makes the human body more comfortable when lying flat on the inflatable bed. The first surface layer and the second surface layer are connected at multiple points to form a plurality of face side chambers. Two adjacent face side chambers can be independent of each other or interconnected. Optionally, the first surface layer is flocking / PVC or breathable and comfortable cloth / PVC, the second surface layer, the third surface layer and the drawstring are PVC, the material of the surrounding belt is flocking / PVC, PVC, TPU or one of them and cloth; the material of the bottom layer is PVC, TPU or one of them and cloth.

[0007] The inflatable bed of this solution improves the comfort of the inflatable bed, improves the sleep quality and use effect of the user, and optimizes the user's experience of the inflatable bed by arranging multiple chambers in direct contact with the human body on the top layer.

[0008] Furthermore, the surface-side chamber at least includes a first surface-side chamber and a second surface-side chamber, and the first surface-side chamber and the second surface-side chamber are connected.

[0009] In the present technical solution, the first side chamber and the second side chamber are connected. The first side chamber may be interconnected or not. The first side chamber and the second side chamber may be chambers of different sizes or shapes and may be evenly distributed in a variety of shapes and patterns on the top layer. Preferably, the first side chamber and the second side chamber are alternately and evenly distributed to make the overall appearance more beautiful.

[0010] Furthermore, it also includes a third surface layer; the third surface layer and the second surface layer are connected to form a back chamber.

[0011] In the present technical solution, the third surface layer and the second surface layer are connected by welding, and when the edge of the third surface layer is connected to the second surface layer, a single dorsal chamber is formed; the dorsal chamber is a cavity arranged under the face side chamber, and when the face side chamber is pressed downward, the dorsal chamber provides it with rebound force, thereby further improving the overall comfort of the inflatable bed; in addition, when the face side chamber is damaged and leaks, the dorsal chamber can continue to be used by the user, and conversely, when the dorsal chamber is damaged, the face side chamber can continue to be used by the user, thus avoiding the problem of the inflatable bed being unusable due to damage to the face side chamber or the dorsal chamber, thereby facilitating use by users, especially outdoors.

[0012] Furthermore, the area of ​​the back side chamber is larger than the total area of ​​all the face side chambers, and the back side chamber is provided with a natural ventilation hole away from the face side chamber, and the natural ventilation hole is connected to the outside of the mattress body.

[0013] In the above scheme, the inflatable bed may or may not be provided with natural vents. In the present technical scheme, it is a scheme containing natural vents. Specifically, the dorsal chamber is connected to the outside through the natural vents. When a human body lies on the top layer, the dorsal chamber is compressed to a certain extent, and a small part of the gas in the dorsal chamber flows out through the natural vents to avoid the internal gas being too full and causing the top layer to be too stiff. Therefore, the setting of the natural vents increases the softness of the top layer; when the human body does not use the inflatable bed, the dorsal chamber bulges again, and the external gas is sucked into the dorsal chamber through the natural vents to form natural regulation. Such a setting further improves the comfort of the inflatable bed. In addition, the amount of gas in the dorsal chamber is automatically adjusted through the natural vents, so that when the inflatable bed is not in use, it is convenient to fold and store it, reducing the storage volume.

[0014] Furthermore, the first surface layer is connected to the surrounding belt, the edge of the second surface layer is connected to the edge of the third surface layer, the connection between the second surface layer and the third surface layer is extended to form an extension piece, and the extension piece, the first surface layer and the surrounding belt are combined to form an upper edge air chamber; the bottom layer is provided with a lower layer four-piece, and the lower layer four-piece, the bottom layer and the surrounding belt are combined to form a lower edge air chamber.

[0015] Furthermore, the first surface layer, the upper four-layer sheet and the surrounding belt are combined to form an upper edge air chamber, and the edge of the back chamber is connected along the upper four-layer sheet.

[0016] Furthermore, the first surface layer is connected to the surrounding belt, the edge of the second surface layer is connected to the third surface layer, the edge of the third surface layer is connected to the surrounding belt, an upper four-layer sheet is provided in the mattress body, and the upper four-layer sheet, the top layer and the surrounding belt are combined to form an upper edge air chamber; the third surface layer is provided with surface vents, the surface side chambers are interconnected, and the surface side chambers are connected to the upper edge air chamber through the surface vents.

[0017] Furthermore, the bottom layer is also provided with a lower four-ply sheet, and the lower four-ply sheet, the surrounding belt and the bottom layer are combined to form a lower edge air chamber, and the upper four-ply sheet and the lower four-ply sheet are both provided with air chamber ventilation holes, and the upper edge air chamber and the lower edge air chamber are both connected to the mattress body through the air chamber ventilation holes.

[0018] Furthermore, an air pump is provided on the surrounding belt, and the air pump is used to inflate the interior of the mattress body.

[0019] In the present technical solution, if the upper edge air chamber and the lower edge air chamber are connected to the interior of the mattress body, the air pump can directly inflate the mattress body and the air chamber; or the air pump and the air chamber are connected through a channel, and the air pump and each air chamber can be connected through several channels, such as one, two or three.

[0020] Furthermore, the air pump is connected with a first channel and a second channel, the first channel is connected with the upper edge air chamber, and the second channel is connected with the lower edge air chamber. Specifically, the first channel and the second channel are connected with the corresponding air chambers through air chamber vents.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] (1) The inflatable bed of the utility model improves the comfort of the inflatable bed, improves the sleep quality and use effect of the user, and optimizes the user's experience of the inflatable bed by arranging multiple chambers on the top layer that are in direct contact with the human body.

[0023] (2) The utility model provides a back chamber so that when the face chamber is pressed down, the back chamber provides a rebound force, thereby further improving the overall comfort of the inflatable bed. In addition, when the face chamber is damaged and leaks, the back chamber can continue to be used by the user. Conversely, when the back chamber is damaged, the face chamber can continue to be used by the user. This avoids the problem of the inflatable bed being unusable due to damage to the face chamber or the back chamber, thereby facilitating use by users, especially outdoors.

[0024] (3) The utility model forms natural adjustment through the setting of natural ventilation holes, further improving the comfort of the inflatable bed, and facilitating its folding and storage, thereby reducing the storage space occupied. BRIEF DESCRIPTION OF THE DRAWINGS

The width of the lower four-layer sheet 500 is greater than that of the extension sheet 114, that is, the volume of the lower edge air chamber 510 is greater than that of the upper edge air chamber 410, which ensures a more stable grip of the inflatable bed and prevents the inflatable bed from moving during use.

[0059] The mattress body 100 is provided with a plurality of drawstrings 600, which connect the top layer 110 and the bottom layer 130; the drawstrings 600 are columnar or sheet-shaped.

The inflatable bed may be provided with or without natural vents. This embodiment takes the case of providing natural vents as an example. Specifically, the area of ​​the back chamber 300 is greater than the total area of ​​all the front chambers. The back chamber 300 is provided with a natural vent 310 away from the front chamber 210, and the natural vent 310 is connected to the outside of the mattress body 100.

[0072] The first surface layer 111 is connected to the surrounding belt 120, the edge of the second surface layer 112 is connected to the edge of the third surface layer 113, the connection between the second surface layer 112 and the third surface layer 113 is extended to form an extension piece 114, and the extension piece 114, the first surface layer 100 and the surrounding belt 120 are enclosed to form an upper edge air chamber 410.
