Abstract
The utility model discloses a ' pneumatic bed with a built in inflator '; the utility model adds a built in inflator on the basis of the original pneumatic bed to aerate for the pneumatic bed.
Description
The utility model relates to a kind of air bed (floating bed), particularly built-in aerating device formula air bed.
Have in the air bag of this air bed one can for self the inflation device.
Existing air bed (floating bed) still needs outer aerating device fully or people to blow in use so far, uses inconvenience.
The purpose of this utility model provides a kind of air bed easy to use, and itself and aerating device are integrated, and portably uses conveniently.
Its solution is: the device that confession self an inflation usefulness is set in air bed (floating bed) air bag.
Accompanying drawing has been described an embodiment of the present utility model.
Accompanying drawing 1: the vertical view of built-in aerating device formula air bed.In the air bag of the present utility model aerating device is arranged.
Accompanying drawing 2: be cutaway view Amplified image along accompanying drawing 1A-A line.It has been described aerating device and reached internal structure in air bag.
Accompanying drawing 1 has been described built-in aerating device formula air bed aerating device (1) in air bag (3).
The aerating device (1) that accompanying drawing 2 has been described built-in aerating device formula air bed reaches internal structure in air bag (3), it has covering (2), air bag (3), spring (4).Spring places the material of inflator (5), and the two ends of inflator (5) are associated with stiffener (7), also has check valve (6), (8).
Stiffener (7) move toward one another under external force, compression spring (4), the air in the inflator (5), inflator (5) by compression after the check valve (8) on inflator (5) wall enter in the air bag (3).Reaction force by spring (4) and inflator (5) when external force is removed resets, and the check valve (6) on the stiffener (7) is opened to communicate with atmosphere and inflated to inflator (5) in simultaneously, and gas replenishment process is finished.Finish airbag aeration through acting on repeatedly.
It is spring (4) that the utility model further improves, and inflator (5) is made the concave spirality, so that increase the compression ratio of the interior air of inflator (5), in order to air bag (3) is inflated.
The aerating device of this utility model (1) can place in lifebuoy, life vest and the small-sized rubber boat.
Claims (2)
1, a kind of air bed (floating bed), particularly built-in aerating device formula air bed is provided with one and can inflates the device of usefulness for self in this air bag, and this aerating device is made up of spring, inflator, check valve, stiffener, it is characterized in that:
A, aerating device (1) place in the air bag (3);
B, spring (4) place the material of inflator (5), and inflator (5) is made the concave spirality, and there is the check valve (8) that communicates with air bag (3) in wall portion;
The two ends of C, inflator (5) are associated with stiffener (7), are equipped with the check valve (6) that communicates with atmosphere on the stiffener (7);
2, aerating device according to claim 1 (1) is characterized in that:
A, place in the lifebuoy;
B, place in the life vest;
C, place in the small-sized rubber boat.
