Abstract

The invention relates to a portable seat cushion capable of generating an alternating supporting force. The portable seat cushion comprises a seat cushion and an inflatable module for inflating the seat cushion, wherein two groups of air bags are arranged in the seat cushion; each group of air bags comprises a plurality of air bags; the two groups of air bags are intersected with each other; the inflatable module comprises an inflatable pump and a reversing valve; the two groups of air bags are connected with the reversing valve respectively through two pipelines; the inflatable pump is connected with the two groups of air bags through the reversing valve; and the inflatable pump alternatively inflates the two groups of air bags through the valve position change of the reversing valve. The portable seat cushion has the advantages that: the stressing condition of the seat cushion is changed by circularly inflating the two groups of air bags, so that people who need to work by sitting posture for a long time or patients who have difficulty in movement and need to sit on wheel chairs for a long time can sit on the seat cushions comfortably.

Description

A kind of cushion of portable generation alternation support force

Technical field

The present invention relates to a kind of cushion, particularly relate to a kind of portable, cushion that can produce the alternation support force.

Summary of the invention

The objective of the invention is provides a kind of cushion of portable generation alternation support force to solve the problems referred to above in order to solve the existing many defectives of cushion in the prior art.

To achieve these goals, technical scheme of the present invention is following:

A kind of cushion of portable generation alternation support force comprises cushion and the inflator module of inflating to cushion, it is characterized in that; Said cushion set inside has two groups of air bags, and every group of air bag comprises a plurality of air bags, and said two groups of air bags are arranged in a crossed manner; Said inflator module comprises inflator pump and reversal valve; Two groups of air bags are connected with reversal valve through two pipelines respectively, and inflator pump connects two groups of air bags through reversal valve, and said inflator pump alternately is two groups of airbag aerations through the valve location change of reversal valve.

The cushion of above-mentioned a kind of portable generation alternation support force is characterized in that said inflator module also comprises pressure switch, is connected with pressure switch between said inflator pump and the reversal valve.

The cushion of above-mentioned a kind of portable generation alternation support force; It is characterized in that; Said inflator module also comprises central control circuit; Said central control circuit connects inflator pump and pressure switch, and said central control circuit also connects reversal valve through servomotor, and said central control circuit also is connected with the program input module.

The cushion of above-mentioned a kind of portable generation alternation support force is characterized in that said inflator module also comprises power module, and said power module comprises battery, charge power supply and direct current input point.

The cushion of above-mentioned a kind of portable generation alternation support force is characterized in that said inflator module also comprises alarm panel, and said alarm panel connects central control circuit.

The beneficial effect that the present invention has:, make that the people or the long-term wheelchair-bound patient of handicapped needs that need adopt sitting work for a long time can be more comfortable when sitting through the stressing conditions that changes cushion is inflated in the circulation of two groups of air bags.

Description of drawings

Fig. 1 is a structural representation of the present invention;

Fig. 2 is a structure principle chart of the present invention.

The specific embodiment

For making architectural feature of the present invention and the effect reached there are further understanding and understanding, cooperate detailed explanation, explain as follows in order to preferred embodiment and accompanying drawing:

Referring to Fig. 1, a kind of cushion of portable generation alternation support force, the inflator module 400 that comprises cushion 200 and inflate for cushion 200; Inflator module 400 is arranged in the shell 100; Cushion 200 set inside have two groups of air bags 300, are respectively A group air bag 310 and B group air bag 320, and every group of air bag all comprises a plurality of air bags; A group air bag 310 is arranged in a crossed manner with B group air bag 320, and two groups of air bags 300 support cushion 200.Inflator module 400 can be organized air bag 310 and the 320 alternately inflations of B group air bag for A, makes the stress point of this product cushion change, thereby reaches final effect.

Referring to Fig. 2; Inflator module 400 comprises inflator pump 410 and reversal valve 420; A group air bag 310 is connected with reversal valve 420 through two pipelines respectively with B group air bag 320; Inflator pump 410 connects A group air bags 310 and B group air bag 320 through reversal valve 420, and the valve location of inflator pump 410 through reversal valve 420 changes and alternately be A

group air bag

310 and 320 inflations of B group air bag, thereby makes A group air bag 310 and B organize being inflated that air bag 320 replaces.Reversal valve 420 also is connected with a gas vent 421 simultaneously, and the effect of gas vent 421 is the gas in the air bag is discharged outside the air bag, and for example when inflator pump 410 was inflated for A group air bag 310, B group air bag 320 just can be discharged the air in the air bag through gas vent 421.

Inflator module 400 also comprises pressure switch 430; Be connected with pressure switch 430 between inflator pump 410 and the reversal valve 420; The effect of pressure switch 430 is to control inflator pump 410 and charges into the air pressure size in the air bag, to avoid overinflation and causes balloon rupture.

Inflator module 400 also comprises central control circuit 440; Central control circuit 440 plays the center control action of whole system; Central control circuit 400 connects inflator pump 410 and pressure switch 430, at first can control the work of inflator pump 410 and opening and closing of pressure switch 430; Secondly central control circuit 440 also connects reversal valve 420 through servomotor 450, can control the valve location of reversal valve 420, so that the air that inflator pump 410 is produced is transported in A group air bag 310 or the B group air bag 320 accurately; Central control circuit 440 also is connected with program input module 460, and the program of program input module 460 inputs can realize the cycle to two groups of airbag aeration times, size of aeration quantity or the like through the working control of Central Control Module 440.

The inflator module 400 of this product also comprises power module 470; Power module 470 is supplied power for inflator module 400; The pattern of multiple power supply is provided simultaneously, because power module 470 comprises battery 471, charge power supply 473 and direct current input point 472 for inflator module 400.

Inflator module 400 also comprises alarm panel 480; Alarm panel 480 connects central control circuit 440; Alarm panel 480 is equivalent to the function of controller; Can control the running of whole system and stop, when system breaks down or warns, can report to the police through alarm panel 480 and come out to let the user know simultaneously.

In sum; Be merely preferred embodiment of the present invention; Be not to be used for limiting the scope that the present invention implements, all equalizations of doing according to the described shape of claim scope of the present invention, structure, characteristic and spirit change and modify, and all should be included in the claim scope of the present invention.
