Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

As shown in FIG. 1 , the present invention provides an independent airway type sports training inflatable cushion, which includes an inflatable component, an air cushion cover 1 and an inner bladder structure arranged in the air cushion cover. The inflatable assembly includes an air pump, which provides an air source for the inflatable cushion; a controller 2, which is used by the operator to control the inflatable cushion to inflate and deflate; an air cavity with a number of through holes connected to the air outlet of the air pump. The air cushion cover 1 is set outside the inner bladder structure, and a sponge layer is arranged on the upper surface of the air cushion cover 1 to improve the comfort of the air cushion; the bottom surface of the air cushion cover 1 is provided with a non-slip wear-resistant layer 3 to prevent the inflatable cushion from being under the action of external force Move freely and increase safety.

As shown in FIGS. 2 and 4 , the liner structure of the present invention is composed of several adjustable airbags 5 placed in parallel. Each adjustable airbag is small in volume and can be quickly inflated and deflated, saving time and improving efficiency. Each adjustable air bag 5 is provided with an air intake hole 10 , and a check valve (not shown in the figure) is provided at the position of the air intake hole 10 , and each air intake hole 10 is respectively connected with the air outlet end of an air intake pipe 6 . Connected, the air intake pipes are independent of each other, and the air intake pipes correspond to the adjustable airbags one by one, ensuring that each adjustable airbag has its own independent air intake channel and does not interfere with each other. An air outlet 11 is also provided on each adjustable air bag 5, and the air outlet 11 communicates with the air outlet pipe. The function of the check valve is to open during inflation, so that the gas can smoothly enter the air bag. When the inflation is over, due to the existence of the pressure in the air bag, the check valve is closed under the action of the pressure, and the intake passage is closed to prevent the gas from overflowing. Guaranteed air tightness. A pressure sensor 7 is also arranged in each adjustable air bag 5, and the pressure sensor 7 is electrically connected to the controller. The controller detects the air pressure in the adjustable airbag, and the pressure sensor uploads the air pressure data to the controller. When the preset pressure is reached, the controller controls to terminate the inflation operation. The pressure sensor can ensure that the air pressure in each adjustable air bag is balanced, so that the pressure of each part of the inflatable cushion is stable, and the user's safety is improved.

The material of the inner tank structure is PVC, which is sturdy and durable. Each adjustable air bag 5 is provided with an overflow hole 12 , and an air overflow valve is arranged at the position of the overflow hole 12 . The function of the air overflow valve is to overflow the excess gas when the air pressure in the air bag is too large, so as to prevent the air bag from being damaged by the excessive air pressure. Each adjustable air bag 5 is provided with a flexible equalizing tube 13 that communicates with its air inlet 10 and extends into the inner cavity of the air bag, and an equalizing air hole is provided on the wall of the equalizing tube 13 . The equalizing tube is conducive to the uniform and rapid filling of the gas into the air bag. Inside each adjustable air bag 5 is provided a pull strap 9 connecting its upper and lower sides. After being inflated with gas, the pull strap is tightened, and the upper and lower sides of the airbag are stretched to generate pressure in the airbag, which is used to fix the shape of the airbag after inflation.

As shown in FIG. 3, the present invention is also provided with an air cavity 8 structure, one side of the air cavity 8 is communicated with the air outlet of the air pump 14, and the other side is provided with a number of through holes, and the through holes are provided with an electrical connection with the controller. Solenoid valve 15; each through hole communicates with the intake end of an intake pipe respectively. A corrugated plate (not shown in the figure) is also arranged in the air cavity 8 to remove the water vapor carried by the gas in the air cavity. During the flow, the water vapor hits the corrugated plate, is blocked by the corrugated plate, and condenses. It is discharged on the surface of the corrugated board to ensure that the inflatable pad is dry, preventing the generation of water and the breeding of bacteria. On the one hand, the setting of the air cavity 8 can buffer the gas directly supplied by the air pump, so that the gas can be buffered in the air cavity, avoid turbulence, avoid impacting the intake pipe, and prolong the service life of the intake pipe; The adjustable airbags are independent of each other and can be inflated by different air intake pipes respectively. The solenoid valve set on the air cavity can be selectively opened or closed under the action of the controller. Inflating all or part of the airbags can make the volume of the inflatable cushion adapt to the needs of more occasions and improve the adaptability. Generally, the number of solenoid valves is greater than or equal to the number of adjustable airbags.

In the present invention, a strap is arranged on the outer wall of each adjustable air bag, and adjacent adjustable air bags are connected by the strap.

The invention has simple structure and strong operability. When using, it is only necessary to determine the number of airbags required for a specific site area, and through the controller, control the opening number of the solenoid valves in the air cavity, and then the corresponding airbags can be quickly inflated through the independent air intake channel. The design of the pressure sensor, drawstring, and overflow hole in the airbag ensures that each airbag has the same shape, and the air pressure in the airbag is balanced, which improves the safety of use.
