Abstract

This invention relates to a multifunctional vacuum pump and its reciprocating linear motion mechanism. The reciprocating linear motion mechanism includes a piston cylinder made of high-wear-resistant engineering plastic, at least two conductive coils disposed on the outer periphery of the piston cylinder, and a piston that is slidably sealed within the piston cylinder. The two conductive coils are spaced apart around the piston cylinder. The piston is an iron-core piston or a magnetic piston. The multifunctional vacuum pump includes a reciprocating linear motion mechanism. Both ends of the piston cylinder are sealed by end plates, each with an inlet pipe and an exhaust pipe. The inlet pipe has an inlet one-way valve, and the exhaust pipe has an exhaust one-way valve. The reciprocating linear motion mechanism of this invention uses a piston cylinder made of high-wear-resistant engineering plastic, which satisfies the requirements for piston movement within the piston cylinder while avoiding the electromagnetic shielding effect of a metal piston cylinder. This allows the magnetic force generated by the coils to directly act on the piston, enabling the piston to reciprocate linearly within the piston cylinder.
