Abstract

The invention discloses a vacuum negative pressure generator. The generator comprises a cylinder body, a movable air cylinder piston rod and a reversing valve assembly, wherein the cylinder body comprises a first end and a second end, the first end and the second end are each provided with an exhaust hole and a suction hole, and a first piston cylinder seat cover and a second piston cylinder seatcover are arranged in a spaced mode in the cylinder body; the movable air cylinder piston rod is arranged in the cylinder body and is movably connected with the first piston cylinder seat cover and the second piston cylinder seat cover in a sealed mode; and the reversing valve assembly is arranged in a mounting cavity. According to the vacuum negative pressure generator, reverse movement of the movable air cylinder piston rod can be realized through switching of communicating air paths of the reversing valve assembly, seamless connection with a generated vacuum negative pressure environment isrealized through the suction holes in the two ends of the cylinder body, it is guaranteed that the negative pressure vacuum state is continuously maintained, and the stability is high.

Description

technical field [0001] The invention relates to the technical field of vacuum negative pressure, in particular to a vacuum negative pressure generator. Background technique [0002] Existing generators that use the reciprocating movement of the piston in the cylinder to generate vacuum negative pressure generally can only provide vacuum negative pressure intermittently, and it is difficult to ensure the continuous and stable operation of the vacuum negative pressure generator. Contents of the invention [0003] The purpose of the present invention is to provide a vacuum negative pressure generator, which can continuously generate vacuum negative pressure through the reciprocating movement of the cylinder piston. [0004] The technical solution adopted in the present invention is: a vacuum negative pressure generator, comprising: [0005] The cylinder body includes a first end and a second end, the first end and the second end are provided with an exhaust hole and an air s...
