Split type vibration and noise reduction air pump

Abstract

The invention relates to a split type vibration and noise reduction air pump. The split type vibration and noise reduction air pump includes a shell base, a shell cover, a vibration and noise reduction cavity, a reciprocating vibration and noise reduction air passage, a pump body and a plurality of extraction and exhaust devices, wherein the shell base is provided with an air inlet hole and an airoutlet hole, the shell cover is detachably connected with the shell base, the vibration and noise reduction cavity is formed in the upper end of the shell base, the reciprocating vibration and noisereduction air passage is arranged on the rear side of the vibration and noise reduction cavity and communicates with the air outlet hole, and the pump body blocks the upper ends of the vibration and noise reduction cavity and the reciprocating vibration and noise reduction air passage and is detachably connected with the shell base; and each extraction and exhaust device includes an air inlet passage, an air outlet passage, an air chamber seat, an air inlet check valve, an air outlet check valve, a leather cup, a swing arm and a swing arm driving device, wherein the air inlet passage is arranged in the pump body and communicates with the air inlet hole, the air outlet passage communicates with the vibration and noise reduction cavity, the air chamber seat is provided with an air chamber, the inner end of the air chamber seat is detachably connected with the pump body, the air inlet check valve is arranged between the air inlet passage and the air chamber, the air outlet check valve isarranged between the air chamber and the air outlet passage, the opening end of the leather cup is detachably connected with the outer end of the air chamber seat, and the swing arm is connected withthe sealing end of the leather cup. When the split type vibration and noise reduction air pump is used, vibration noise is small, and installation and disassembly are convenient.

Description

technical field [0001] The invention relates to the field of air pumps, in particular to a split type air pump for vibration reduction and noise reduction. Background technique [0002] The invention of Chinese patent application number: 201410656686.X discloses an aquaculture oxygen-increasing pump, which includes a casing, a rotating motor is arranged in the casing, a coaxial flywheel is fixed on the output shaft of the rotating motor, and the end face of the flywheel One end of the crank is hinged, and the other end of the crank is hinged with the driving end of the slide rod. The slide rod is slidably connected to the housing in an axially movable manner. There is an air chamber in the housing, and the air chamber faces one side of the slide rod. It is a deformable membrane, the driven end of the slide rod is connected with the middle part of the deformable membrane, the air cavity is connected with the outside through the air inlet pipe and the air outlet pipe, and an e...
