Description

Technical Field

[0001] The utility model belongs to the technical field of air cushions, and particularly relates to a portable ventilated air cushion. Background Art

[0002] Air cushions are widely used in daily life. In order to avoid bedsores, patients confined to bed use inflated air cushions, which facilitates turning over the patients in bed.

[0003] Chinese Utility Model Patent CN 221307768 U discloses a mattress. By arranging an air cavity inside the inflated mattress and filling air into the air cavity, the inflated mattress can have better elasticity and flexibility, improving the comfort of the user. By arranging multiple layers of aluminum films inside the air cavity, the heat loss of the inside of the inflated mattress caused by the cold air outside can be effectively blocked, thus keeping the inside of the inflated mattress warm and providing a more comfortable sleeping environment. The aluminum film can effectively isolate moisture, prevent the top of the inflated mattress from getting damp, and the aluminum film is relatively light, so adding it inside the inflated mattress will not increase too much weight, making the inflated mattress convenient to carry. However, such an air cushion is not ventilated, inconvenient to use, and the part where the user contacts the air cushion is prone to sweating, causing hygiene problems such as eczema; and it is inconvenient to fold and carry. There are also other ventilated air cushions on the market that use grooves on the air cushion to form a ventilation effect. However, such a ventilation effect is not good.

[0004] Therefore, there is a need for an air cushion with a simple structure, good ventilation effect, and capable of independent ventilation. Summary of the Utility Model

[0027] The present utility model will be further described below with reference to the accompanying drawings in specific embodiments:

[0028] Referring to Figures 1 to 6 as shown, a portable ventilation air cushion includes a support pad 1 and an inflation device 3 connected to the support pad 1 for supplying air; the support pad 1 includes a body 11 and a support airbag 12 and a ventilation airbag 13 arranged in the body 11, the support airbag 12 and the ventilation airbag 13 are independently and spaced apart, and a plurality of exhaust holes 14 communicating with the ventilation airbag 13 are arranged on the outer surface of the ventilation airbag 13; by the independently and spaced-apart support airbag 12 and ventilation airbag 13, the two effects of support and ventilation are separated, that is: the support airbag 12 plays a support effect, and the ventilation airbag 13 blows air to the outside through the exhaust holes 14; during use, even when the ventilation airbag 13 does not work, the support airbag 12 can still play a support effect; at the same time, the support airbag 12 and the ventilation airbag 13 are arranged in the body 11, which can optimize the structure of the support pad 1, reduce the thickness of the support pad 1, and is also convenient to carry.

[0029] There are many ways to form the support airbag 12 and the ventilation airbag 13, and their main purpose is to facilitate the air cushion to support the user and blow air to the user on the support pad 1 at the same time.

[0030] In this embodiment, both the support airbag 12 and the ventilation airbag 13 are arranged in a "Z" shape, and the support airbag 12 and the ventilation airbag 13 are spaced apart. The "Z" shape is a shape with multiple bends, so that the support airbag 12 and the ventilation airbag 13 can increase the contact points or the contact area, which is convenient for supporting and blowing air to the user.

[0031] It can also be: A plurality of the support air bags 12 and ventilation air bags 13 are provided, and the plurality of support air bags 12 and ventilation air bags 13 are arranged at intervals longitudinally; adjacent support air bags 12 communicate with each other, and adjacent ventilation air bags 13 communicate with each other. The independently connected support air bags 12 and ventilation air bags 13 are arranged at intervals longitudinally, which can reduce the thickness of the support pad 1 while increasing the structural strength.

[0032] It can also be: An isolation member 2 is provided inside the main body 11. The isolation member 2 is bent inside the main body 11 and both ends of the isolation member 2 are in contact with the side wall of the main body 11. The isolation member 2 divides the interior of the main body 11 into a support air bag 12 area and a ventilation air bag 13 area; specifically, the isolation member 2 is bent in an "S" or "Z" shape multiple times inside the main body 11, so that the space inside the main body 11 is divided into two areas: the support air bag 12 area and the ventilation air bag 13 area; the support air bag 12 area forms support for the human body, and the ventilation air bag 13 area forms blowing and heat dissipation for the human body.

[0033] In order to enable the exhaust holes 14 to better blow and dissipate heat to the human body, the position of the exhaust holes 14 is lower than or equal to the upper end surface of the support air bag 12; in this embodiment, it is preferably that the position of the exhaust holes 14 is lower than the upper end surface of the support air bag 12. In this way, when the user uses it, the exhaust holes 14 reduce contact with the user and make the exhaust of the exhaust holes 14 smoother.

[0034] At the same time, in order to further increase the heat dissipation effect, the upper end surfaces of the support air bag 12 and the ventilation air bag 13 both protrude outward. A through groove 16 is formed between the protruding parts 15 of adjacent support air bags 12 and ventilation air bags 13. Both ends of the through groove 16 penetrate through the support pad 1. Air flow on the upper surface of the support pad 1 is formed through the through groove 16. At the same time, the contact area when the user uses it can be reduced.

[0035] The cross-sectional width of the protruding part 15 is smaller than the cross-sectional width of the support air bag 12 or the ventilation air bag 13. In this way, it is convenient to form the through groove 16, and the through groove 16 is connected to one end surface of the isolation member 2. The isolation member 2 provides a supporting effect on the bottom of the through groove 16.

[0036] In this embodiment, a base 4 is further included, and the support pad 1 is arranged on the base 4; the material of the base 4 is a foldable soft material; or, the base 4 is an inflatable air cushion seat, which is convenient for storing the base 4, facilitating carrying and moving.

[0037] An inflation port communicating with the inflation device 3 is provided on each of the support airbag 12 and the ventilation airbag 13. The inflation port of the support airbag 12 is the first inflation port 51, and the inflation port of the ventilation airbag 13 is the second inflation port 52. Inflation devices 3 are respectively provided at the two inflation ports. The two inflation devices 3 respectively inflate the first inflation port 51 on the support airbag 12 and the second inflation port 52 on the ventilation airbag 13, which can improve the inflation efficiency.

[0038] It can also be: the two inflation ports are connected to one inflation device 3, that is, one inflation device 3 inflates the first inflation port 51 of the support airbag 12 and the second inflation port 52 of the ventilation airbag 13. It can also be that after one inflation device 3 finishes inflating the support airbag 12, it then inflates and blows air into the ventilation airbag 13.

[0039] The above embodiments are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
