形逆止弁を使用しても機能には何ら影響なない。The present invention relates to a manual suction pump. In the conventional pump, when the push button is pressed, the pump is immediately pumped up by the pressurizing action. Needless to say, it is indispensable that it immediately appears when pressed, depending on the purpose of use and application. However, there is a drawback that both hands cannot be used in the working posture. The present invention relates to a suction pump capable of discharging a solution after completion of pressing. The present invention will be described with reference to the drawings. When the push button (1) provided on the upper end of the pump is pressed, the discharge pipe (2) protruding from the push button (1) is moved to the cylinder (6).
The upper part of the piston (5) is slidably provided through the upper part of the piston (5), and the lower end of the upper part of the piston (5) is attached to the upper part of the piston (5). At that time, the ball type check valve (4) built in the piston (5) is pushed up by the solution filled in the lower tank chamber (12) to be in an open state, and the piston (5) reaches the bottom dead center. Then, the upper tank chamber (11) is filled with the solution, and the check valve (9) built in the suction pipe (8) at that time is closed by the pressurization of the piston (5). And push button (1) which pushed down
Is released, the piston (5) rises by the force of the spring (7). At the same time, the check valve (4) closes,
As the piston (5) rises, the solution filled in the upper tank chamber (11) is guided through the discharge port (3) formed at the lower end of the discharge pipe (2) and discharged from the discharge pipe (2). At the same time, a negative pressure is generated in the lower tank chamber (12) at the lower end of the cylinder (6). Therefore, the ball check valve (9) built in the suction pipe (8) airtightly inserted in the cylinder (6) is opened, and the solution in the solution chamber (13) is discharged from the suction pipe (8). Upon introduction, the lower chamber (12) is filled with the solution. When the push button (1) is pushed down, the piston (5) is also lowered, the upper tank chamber (11) is filled with the solution, and the push button (1) is returned and raised, so that the upper tank chamber (11) The solution is a pushing manual pump of the type in which the solution is discharged by the upward pressurization of the piston (5), and at the same time, the negative pressure is generated in the lower tank chamber (12) due to the upward movement of the piston (5) to suck the solution. Also, the ball check valve (4) built in the piston (5) and the ball check valve (9) built in the suction pipe (8) do not function even if a swing check valve is used. It has no effect.
