Novel double-cylinder air pump

Abstract

The invention provides a novel double-cylinder air pump. The novel double-cylinder air pump comprises a motor, a shell, a front end cover, a cam, a slide block, a slide block sleeve, connecting rods,pistons, a U-shaped lock piece, guide columns, cylinders, sheets, screws, front and back sealing pieces, left and right sealing pieces and small screws. The motor is screwed on the back end surface ofthe shell; the front end cover is screwed on the front end surface of the shell; a motor shaft extends into an inner cavity of the shell; the cam is pinned on the motor shaft; a thin end of the cam is hinged to a hinge column at the back part of the slide block; the slide block slides on the guide column on an inner ring of the slide block sleeve; the connecting rods protrude from two sides of the slide block sleeve; the pistons are mounted at the tail ends of the connecting rods; two cylinders are mounted on two sides of the shell respectively; the sheets are screwed on the cover walls of the outer ends of the cylinders to form one-way valve structures with intake holes; after the motor is started, the cam rotates to drive the slide block to rotate, the slide block pushes the slide blocksleeve to move left and right, and the pistons perform a reciprocating motion in the cylinders; and air is sucked into the cylinders from the intake holes, and is exhausted from exhaust holes into external pipelines.

Description

technical field [0001] The invention relates to an air pump, in particular to a novel double-cylinder air pump. Background technique [0002] Air pumps, as a device that removes air from a closed space or adds air from a closed space, are more and more widely used in industry and life, especially electric air pumps. The electric air pump is an air pump powered by electricity. It compresses air continuously through electricity to generate air pressure. It is mainly used in pneumatic gluing, car inflation, etc. In the current electric in-line double-cylinder air pump, the pistons are distributed on both sides of the motor, and two cams are used to drive the pistons to reciprocate. The stability is poor during use, the noise is large, the air output is small, the inflation volume is small, and the inflation time is long. [0003] Therefore, it is necessary to design a new type of air pump that can overcome the defects of the in-line double-cylinder air pump in use. This is of...

AI Technical Summary

Problems solved by technology

The electric in-line double-cylinder air pump currently used, the piston is distributed on both sides of the motor, and two cams are used to drive the piston to do reciprocating motion. In use, the stability is poor, the noise is large, the air output is small, the inflation volume is small, and the inflation time is long.
