ABSTRACT:
In the reciprocating pump P, the pressure chamber 30 is formed by an atomizing tube 15, a piston 28, and a cylinder 20. The pressure chamber 30 has a check valve 24 that opens and closes the inlet of the said pressure chamber 30 and a ball-shaped stirring material 25 moving freely in the pressure chamber 30 that stirs the mixture in the pressure chamber 30. On the other hand, pumping space is formed by the piston 28 and the cylinder 20 in the reciprocating pump P, apart from the pressure chamber 30. The pumping space 29 is occupied by the mixture pumped up when the push button 17 is returned to its home position and communicating holes are provided through which the mixture is discharged into the container 10 when the push button is pressed. The atomizer of an reciprocating pump type of the present invention can stir sufficiently and atomize a liquid-powder mixture when used.
