Abstract

The invention belongs to an electromagnetic diaphragm pump. The pump comprises electromagnets; an oscillator vibrating along with changes of the polarity of the electromagnets; diaphragms arranged at the end portion of the oscillator; diaphragm stands and diaphragm holding portions that can clamp and fix the periphery of each diaphragm; and an oscillator cover covering the oscillator. A pair of inner separation chambers closer to the inside than the diaphragms is formed by means of the diaphragm stands and the diaphragms, such that the oscillator cover separated from the diaphragm stands can be installed in a way that the pair of inner separation chambers is communicated.

Description

technical field [0001] The present invention relates to, for example, an electromagnetic diaphragm pump for household fuel cells, and an electromagnetic diaphragm pump for pressure feeding fuel gas such as LPG. In particular, it relates to an electromagnetic diaphragm pump, which is equipped with a pump when the fluid is blown to the inside of the pump due to damage to the diaphragm. In the case of leakage, the leaked liquid cannot enter the current-carrying part of the isolation structure, and the isolation effect of the isolation structure can be reliably given in advance to prevent accidents caused by leakage in advance, and the performance degradation of the electromagnetic pump can be suppressed. . Background technique [0002] Conventionally, an electromagnetic diaphragm pump is known. As shown in the schematic top sectional view of FIG. Spit out (discharge). [0003] In such an electromagnetic diaphragm pump, generally, a pair of opposing diaphragms 520 are arranged...
