The present invention relates to the field of outdoor product technologies, and in particular, to an air mattress.
An air mattress is a mattress that expands in volume after being inflated. The air mattress features strong flexibility and good elasticity. The air mattress is easy to carry after deflation, and is convenient to use, and therefore is widely used in various fields. Particularly, advantages of the air mattress are more prominent in outdoor products. Different users have different elasticity requirements for the mattress. Existing air mattresses are generally low in air pressure, insufficient in support force, uneven in bed surface, uneven in support, insufficient in stability, prone to tip, inconvenient in inflation and deflation, subjected to slow air leakage, etc. In addition, in the conventional technology, elasticity of the air mattress is usually adjusted through inflation and deflation. To be specific, when the elasticity is relatively large, the air mattress is deflated to be softer. When flexibility of the air mattress is adjusted in this manner, the mattress is particularly prone to collapse downward after deflation. In addition, because the air mattress is relatively light, when air in the mattress is insufficient, the air mattress is prone to tip when a user sits on an edge of the mattress, that is, flexibility and support requirements for the air mattress cannot be satisfied during actual use.
The present invention provides an air mattress, which can ensure a support requirement for the air mattress during softness adjustment of the air mattress.

Referring to
The air mattress provided in this embodiment includes the mattress body 100 and two air charging/discharging valves 200. A top of the mattress body 100 is the bed surface 10 for sleep, and the mattress body 100 has at least two mutually separated air chambers: the first air chamber 40 and the second air chamber 50. The two air charging/discharging valves 200 respectively inflate and deflate the first air chamber 40 and the second air chamber 50. The first air chamber 40 is located below the bed surface 10 and can adjust softness and comfort of the bed surface 10 through inflation and deflation of the first air chamber 40. The second air chamber 50 is disposed on the outer side of the bed surface 10, and the second air chamber 50 can be inflated through the air charging/discharging valve 200 to ensure support of the entire structure, to prevent support of the air mattress from becoming weak because the air mattress is in a soft state, and especially prevent a user from slipping off from the bed surface 10 because the bed surface 10 is prone to be deformed during load bearing after the bed surface 10 becomes soft.
In a further feasible manner of this embodiment, the mattress body 100 further includes a bed bottom 20, the bed bottom 20 is located below the first air chamber 40, a third air chamber 90 is further formed inside the mattress body 100, the third air chamber 90 communicates with the first air chamber 40, and the third air chamber 90 is located on an outer side of the bed bottom 20 and surrounds the bed bottom 20.
During actual use, if air pressure of the mattress body 100 is relatively large and overall support is relatively high, when a user sits on one side, the air mattress is prone to tip or warp. In this embodiment, the third air chamber 90 can improve a contact area, and softness of the third air chamber 90 is consistent with softness of the bed surface 10, so that the air mattress is not prone to tip when overall support of the mattress body 100 is good.

In this embodiment, the side fender 60 is better sealed after being connected to the bed surface 10 and the bed bottom 20, and a process can be simplified to reduce costs. In addition, the side fender 60 can bear larger pressure, so that an overall structure is stronger.

Finally, pressure between the first air chamber 40 and the second air chamber 50 can be further adjusted by using the first separation film layer 70. Specifically, when the first air chamber 40 is deflated, the first separation film layer 70 is elastically deformed toward the first air chamber 40, and when the first air chamber 40 is inflated, the second air chamber 50 is extruded.
In a further feasible manner of this embodiment, the first separation film layer 70 is connected to the side fender film layer 602 through hot melt, and the upper end of the first separation film layer 70 is located between an upper surface of the bed surface 10 and the side fender 60.

In a further feasible manner of this embodiment, a fender reinforcement cloth 80 is laminated on an outer side of the side fender 60.
In this embodiment, the fender reinforcement cloth 80 can improve a high-pressure resistance capability of the side fender 60, to prevent the side fender 60 from bulging outward when the side fender 60 is subjected to high pressure.

In addition, the wires 30 are disposed between the bed-surface base cloth 101 and the bed-bottom base cloth 201, so that hardness is better in an inflated state and support for a human body is also better, and when the human body is lying on the bed surface, the bed surface is not deformed to become uneven. Moreover, with the existence of the structure of the third air chamber 90, in combination with the wire structure, it can be ensured that the bed surface 10 and the bed bottom 20 have better support for the human body, and it can be further ensured that the mattress body 100 does not tip or warp.
