Structure of the invention Means for solving the problems The small sprayer of the invention has a mounting member 2 that is fitted and attached to the outer surface of the mouth of the container body 1 and a cylinder 3 that is suspended from this member 2 into the mouth. Formed with parts,
The cylindrical valve seat 4 of the suction valve from the bottom of this cylinder 3
The main body part 5 is stood up, the cylindrical piston 6 is inserted into the cylinder 3, and the piston 6 hangs down from the piston 6 to the vicinity of the valve seat 4 via a base plate 8 having several through holes 7 in the circumferential direction. an elevating member 10 in which a rod-shaped suction valve body 9 is made of the same parts, and a stem 13 whose lower end is fixed in communication with the cylindrical piston 6, protrudes upward, and has a spray head 12 having a nozzle pipe 11 at its upper end and which is fixed in communication with it. a return spring 14 provided in the cylinder 3 and pushing upwardly the movable parts of the elevating member 10, the stem 13, the spray head 12, and the nozzle pipe 11; and a discharge spring provided above the stem 13. A valve 15 and a suction pipe 1 which is fixedly connected to the bottom of the cylinder 3 and hangs down inside the container body 1.
6, and a stop ring 17 which is attached and fixed to the mounting member 2 and presses the movable part to a predetermined return position via the stem 13.

る。 Function In the above, under normal conditions, the valve body 9 is in a position with a gap between it and the valve seat 4 as shown in the figure, and therefore the suction valve is in the open state, but the upper part of the stem 13 is closed. Since the discharge valve 15 is closed, the cylinder 3 and stem 13 are substantially filled with liquid sucked up through the suction valve. In this state, when the elevating member 10 is pushed down by the spray head 12 through the stem 13 against the return spring 14, the valve body 9 is inserted into the valve seat 4 and the suction valve is closed. The upper end opening is the discharge valve 15.
Since the hydraulic pressure inside the cylinder 3 and stem 13 increases due to the downward movement, when this hydraulic pressure reaches the specified value, the discharge valve 15 is pushed upward and opened, and the pressurized liquid is released. The liquid is ejected from the discharge valve 15 through the spray head 12 and outward from the nozzle pipe 11.

１サイクルが終わる。 When the pressing down operation is stopped when the pressurized liquid is approximately jetted out, the movable parts of the elevating member 10, stem 13, spray head 12, and nozzle pipe 11 are returned to the illustrated state by the spring 14; When the suction valve is finished, the pressure inside the cylinder 3 and stem 13 becomes negative, so when the suction valve is opened as shown, the liquid inside the container body 1 flows into the cylinder 3 and the stem 13 through the suction pipe 16 and the suction valve. , one cycle of spraying operation is completed.
