In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1 to 4, an inflator with a compact structure comprises a fixing member 1, a rotary driving member 2, a first driving wheel 3, a second driving wheel 4, a cylinder 5 and a piston rod 6 matched with the cylinder 5, wherein a containing groove 31 for containing the second driving wheel 4 is arranged inside the first driving wheel 3, the first driving wheel 3 is rotatably connected with the fixing member 1, the second driving wheel 4 is connected with an output shaft of the rotary driving member 2, the first driving wheel 3 is in transmission connection with the second driving wheel 4, the rotary driving member 2 and the cylinder 5 are both fixed relative to the fixing member 1, the first driving wheel 3 is provided with an eccentric convex column 32, and the eccentric convex column 32 is rotatably connected with the piston rod 6.
When the reciprocating type piston rod driving device is used, the rotating driving piece 2 drives the second driving wheel 4 to rotate, the second driving wheel 4 drives the first driving wheel 3 to rotate, the first driving wheel 3 drives the piston rod 6 to do reciprocating motion. In the above embodiment, the second transmission wheel 4 is located inside the first transmission wheel 3, so that the occupied space of the first transmission wheel 3 and the second transmission wheel 4 is small, and the inflator has a compact structure and a small size.
The transmission between the first transmission wheel 3 and the second transmission wheel 4 can be carried out by a conventional transmission means, such as a friction transmission, but preferably, as shown in fig. 4, said first transmission wheel 3 is provided with an internal toothing 33 and said second transmission wheel is provided with an external toothing 41 meshing with said internal toothing 33.
As shown in fig. 1, the fixing member 1 is integrally formed with the cylinder 5, so that a worker does not need to connect the fixing member 1 and the cylinder 5 when assembling the inflator.
As shown in fig. 1 to 3, the first driving wheel 3 and the second driving wheel 4 are located at the upper end of the fixing member 1, the rotary driving member 2 is located at the lower end of the fixing member 1, the fixing member 1 is provided with a through hole 8 for the output shaft of the rotary driving member 2 to pass through, the output shaft of the rotary driving member 2 passes through the through hole 8 and then is connected with the second driving wheel 4, the output shaft of the driving member is limited by the fixing member 1, and the stability of the rotary driving member 2 is ensured.
As shown in fig. 1 to 3, the compact inflator further includes a connecting member 7, and the first driving wheel 3 is rotatably connected to the fixing member 1 through the connecting member 7; mounting 1 includes first fixed block 11 and can dismantle the second fixed block 12 of being connected with first fixed block 11, the centre gripping of first fixed block 11 and second fixed block 12 connecting piece 7, when the user need dismantle connecting piece 7 in order to dismantle first drive wheel 3, only need make first fixed block 11 and the separation of second fixed block 12 can, convenient to use person dismantles fast.
