More specifically, the present invention relates to an electromagnetic vibration type pump that is mainly used for intake / exhaust of air to / from indoor air mats and air beds, oxygen supply in fish tanks and domestic septic tanks, or sampling of inspection gas in pollution monitoring.

  Conventionally, a pump as shown in FIG. 21 is used as an electromagnetic vibration type pump that draws and discharges fluid by using the vibration of a vibrator having a permanent magnet based on the magnetic interaction between an electromagnet and a permanent magnet. (For example, Patent Document 1).

JP-A-8-270556

  In such a pump configuration, atmospheric air is sucked from the intake port 206 and then collected by the filter 203 and then flows into the pump chamber of the pump casing portion. The dust cannot be removed completely. For this reason, there is a problem that fine sand or the like that has passed through the filter enters between the diaphragm used in the pump and the metal fitting holding the diaphragm, and the diaphragm is damaged while the operation is continued, and its life is shortened. . In addition, there is a problem that the damage of the diaphragm is detected at an early stage, the number of maintenance work for replacing the diaphragm is increased, and the operation rate of the pump is lowered.

  In view of the above circumstances, an object of the present invention is to provide an electromagnetic vibration pump capable of improving the dust collection function, reducing the number of maintenance operations, and improving the operating rate.

  The electromagnetic vibration type pump of the present invention is an electromagnetic vibration type pump, and has an intake port for sucking air and an exhaust port for discharging the air in an internal cyclone chamber, and is sucked into the cyclone chamber from the suction port. It is characterized by comprising a centrifugal dust collector having a cyclone generator provided with a generator for generating a cyclone action in the atmosphere.

  As described above, according to the present invention, dust, dust, and the like contained in the inhaled air can be collected in the cyclone chamber by centrifugal force due to the cyclone action. Further, since dust or dust once entering the dust storage portion or the bottom of the main body can be collected without flowing back into the cyclone chamber, the dust collection function can be enhanced. Thereby, clean air can be supplied to the pump chamber. Therefore, it is possible to reduce the number of maintenance work of the pump and improve the operating rate.
