Description

Technical Field

[0001] The utility model belongs to the technical field of air pumps, and in particular relates to an L-shaped air pump. Background Art

[0002] Air pumps are also called air pumps. Air pumps work by running a motor. When pumping air, the check valve of the piston is opened by the atmospheric pressure, and the gas enters the cylinder. When inflating, the check valve is closed by the air pressure in the cylinder, and the gas enters the tire. Air pumps are widely used in automobiles, motorcycles, bicycles and other fields.

[0003] The internal transmission components of the current air pump are too complicated, resulting in a large internal space. In addition, the air outlet and the air pump are in a straight line, which makes the overall length of the air outlet and the air pump longer, resulting in a large overall space. For this reason, the utility model designs an L-shaped air pump. Utility Model Content

[0006] Preferably, the air outlet direction of the air outlet is perpendicular to the movement direction of the piston head.

[0007] Preferably, the end of the mounting seat is provided with a plurality of bolt holes for fixed connection with the brushless motor.

[0009] Preferably, the piston rod and the piston head are an integrally formed one-piece structure, and an annular sealing ring is sleeved on the piston head.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: in the utility model, the brushless motor, the mounting base and the air cylinder are distributed in an L shape, and the brushless motor directly drives the driven gear plate to rotate through the driving gear, thereby directly driving the piston rod and the piston head to reciprocate in a straight line. The overall structure is simple and the occupied space is reduced. In addition, the air cylinder and the air outlet are designed as an integrated structure, and the air outlet of the air outlet is perpendicular to the direction of movement of the piston head in the air cylinder, which can be shortened to the overall length of the air cylinder and the air outlet, reducing the space occupied by the overall air pump, and the structure is more compact.
