Abstract

This invention relates to gas variable displacement mechanical field, especially a diaphragm pump. It has machine case, in which is arranged with diaphragm pump components. The back side of machine case is set with electric engine which drives diaphragm pump components. Boss, diaphragm part and driving part form a gas absorbing and exhausting function element. At the interior of machine case, the air flow passes air inlet opening, semicircular air inlet valve, pump chamber, barrel type air outlet valve and air outlet opening in turn. This invention reduces energy consumption and working noise.

Description

technical field

[0001] The invention relates to the field of gas variable capacity machinery, in particular to a diaphragm pump. Background technique

[0002] The existing diaphragm pump has a structure as shown in FIG. 1 . In this figure, 21 is a motor, 22 is an output shaft of the motor 21, 23 is an eccentric wheel fixed on the output shaft 22, 24 is a drive shaft obliquely fixed on the eccentric wheel 23, and 26 is a drive shaft that can be fixed relative to the drive shaft 24. 27 is a casing, 28 is a cylinder part, and 29 is a valve cover of the drive body mounted for rotation. 31 is a diaphragm part, 32 is a cylindrical discharge valve, and this diaphragm part 31 and discharge valve 32 are integrally formed and comprise the diaphragm main body 30. The diaphragm main body 30 is fixed by the cylinder portion 28 and the valve cover 29 . In addition, 33 and 34 are the valve chamber part (common room) integrated with the valve cover 29, and a discharge port, 35 is a sucti...
