The working principle is as follows: when the device is started, the driving gear 10 starts to rotate under the driving of external torque, the driving gear drives one end of the driving rod 8 close to the driving gear 10 to do circular motion, so that the other end of the driving rod 8 pushes the piston I2 to slide up and down in the cylinder I1, when the piston I2 moves upwards, the piston I1 pushes the gas upwards, the gas at the moment enters the spherical cavities 18 of the gas inlet 4 and the gas outlet 5, the movable ball 7 moves upwards to abut against the inclined hopper 6 in the spherical cavity 18 of the gas inlet 4, the gas cannot be sprayed out from the gas inlet, the spherical cavity 18 of the gas outlet 5 is provided, the inclined hopper 6 in the movable ball 7 is opened due to the upward movement of the gas, the gas is sprayed out from the gas outlet 5 to inflate an article to be inflated, when the piston I2 moves downwards, the external gas is sucked into the cylinder I1, and the inclined hopper 6 in the gas outlet 5 is blocked downwards by the movable ball 7 at the moment, the inclined hopper 6 in the air inlet 4 is opened due to the downward movement of the movable ball 7, so that the air enters the cylinder 1 from the air inlet 4, the air outlet 5 sucks back the sprayed air when air supplement is avoided, and the mode of inflating and air supplement is utilized, the working process of the inflator is simplified, the working efficiency is improved, and the cost is saved.

When the pressure inside an object to be inflated is high, after the device is started, the driving disc 15 starts to rotate under the drive of external torque, the driving disc drives the driving block 16 to rotate, the driving block 16 drives the driven block 17 to rotate, the driven disc 14 drives the connecting rod 9 and the power-assisted gear 11 to rotate, the power-assisted gear 11 idles until the piston I2 moves upwards to extrude the gas inside the cylinder I1 to be high in pressure, the extrusion bag 3 is pressed by high pressure, the gas inside the extrusion bag enters the cylinder II 19, the piston II 20 inside the cylinder II 19 is pressed to move upwards, the power-assisted gear 11 is jacked to a position meshed with the driving gear 10, the driving gear 10 is meshed with the driving gear 10, the driving gear 10 obtains the meshing power of the power-assisted gear 11, the driving gear and the driving rod 8 apply power to the driving rod 8 together, so that the piston I2 has enough power to move upwards, and the gas inside the cylinder I1 is smoothly squeezed into the object to be inflated, by the aid of the method, the problem that the device cannot be used for inflating due to high internal pressure of the article when the article is inflated can be effectively avoided.

When the article to be inflated is inflated with enough gas, the combined action of the power-assisted gear 11 and the driving gear 10 is not enough to enable the piston I2 to continue to move upwards, at this time, the power-assisted gear 11 and the driving gear 10 have larger resistance, and at this time, the interaction force between the driving block 16 and the driven block 17 becomes larger and larger until the driving block 16 and the driven block 17 bend due to the larger action force, the driving block 16 cannot drive the driven block 17 to rotate, the driving block 16 idles, the connecting rod 9 and the power-assisted gear 11 driven by the driven block 17 stop rotating, the power-assisted gear 11 stops providing meshing power for the driving gear 10, the piston I2 does not move upwards any more, and the phenomenon that after the inflation is completed, the power is too large to continuously inflate the article to cause the internal pressure of the article to be too large and break is avoided.
