By pushing down the actuating member through the push-down head, the liquid in the cylinder is sprayed from the nozzle hole via the discharge valve, and as the actuating member rises, the inside of the cylinder becomes negative pressure. 2. Description of the Related Art A manual sprayer is known in which the liquid inside the container is sucked into a cylinder through a suction valve. In this type of sprayer, for example, when the spray liquid is a liquid in which a drug or the like is dissolved, the dissolved substance solidifies as it dries, which causes the nozzle hole to become clogged. That is, when a sprayer is used, liquid adheres to the inside of the nozzle hole, but as the adhering liquid dries, the dissolved substance sticks to the inner surface of the nozzle hole, and the stuck substance becomes enlarged with repeated use. Eventually, the nozzle hole was blocked.

た液体を除去する。 In the above configuration, when the actuating member 17 is pushed down for the first time via the push-down head 32, the suction valve
Since both discharge valves are closed, the pressurized chamber A formed by the inside of the cylinder below the lower cylindrical piston part 25 and the inside of the outer cylinder 22, and the inside of the large diameter cylinder above the large diameter piston part 24. Since it communicates with the pressurizing chamber B formed by the through hole 27 and the vertical groove 28, the inside of the pump chamber formed by these is pressurized. When pressurized further, the difference in diameter between both cylinders causes the communication pipe member 1 to
8 is further lowered with respect to the push-down head 32, the discharge valve 37 is opened, and the fluid inside the pump is jetted out from the nozzle hole. When you use the sprayer for the first time, there is air in the pump chamber, so air will be blown out. Since the actuating member 17 descends while spraying with the discharge valve open, the air cylinder chamber 29 also descends, and the air cylinder plunger is inserted into the air cylinder chamber and the room air is jetted out through the discharge valve hole. let When the actuating member 17 stops descending, the discharge valve 37 is closed by the upward force of the spring 30, and when the push-down head is released, the actuating member rises. In order to create a negative pressure in the pump chamber, the suction valve 6 opens to suck in the liquid inside the container, and to create a negative pressure in the air cylinder chamber, outside air is sucked in through the nozzle hole, discharge path, and discharge valve hole. Since the liquid is sucked into the pump chamber, the next time the actuating member is pressed down, it will be sprayed, and when the actuating member is raised, the outside air will be sucked in to remove the liquid adhering to the inside of the nozzle hole.

There is. In this embodiment, when the actuating member 17 is pushed down via the push-down head 32, the interior of the pump chamber consisting of the pressurizing chamber A and pressurizing chamber B communicated through the through hole 55 is opened, as in the case of the first embodiment. When the pressure is increased, the communication pipe member 18 is lowered due to the difference in diameter between the cylinders 5 and 36, the discharge valve 37 is opened, and the nozzle hole 35 is opened.
Spray from. By lowering the operating member, the air cylinder plunger 41 enters the discharge pipe hole which also serves as the air cylinder chamber 29. When the actuating member stops descending, the discharge valve 37 closes, and when it rises, the suction valve 6 opens, allowing liquid to enter the pump chamber. At the same time, negative pressure is created in the cylinder chamber, which is the vertical part of the discharge passage, and outside air is sucked in through the nozzle hole. .

る。 The present invention has the above-mentioned structure, in which liquid is sucked into the pump chamber from the container body to which the cylinder is mounted by vertical movement of the actuating member raised from the cylinder, and the liquid is pumped into the pump chamber formed at the upper end of the actuating member. In a sprayer that is designed to spray from the nozzle hole in the lower head, when the actuating member that sucks the liquid inside the container rises, outside air is sucked in through the nozzle hole. This makes it possible to remove the liquid that is present in the nozzle hole by the suction outside air, and therefore, by drying the adhering liquid, it is possible to prevent substances dissolved in the spray liquid from sticking to the inner surface of the nozzle hole, thereby preventing clogging of the nozzle hole. I can do it.

嵌合させたことを特徴とする手動式噴霧器。 The cylinder 5 has a cylinder 5 attached to the container body 1, and an actuating member 17 whose lower part is inserted into the cylinder so as to be movable up and down and urged upward, and a nozzle formed at the upper end of the actuating member. Push-down head with hole 3
2, the liquid in the cylinder is ejected from the nozzle hole 35 via the discharge valve 37, and as the actuating member rises, the inside of the cylinder becomes negative pressure. In a manual sprayer configured so that the liquid inside the container is sucked into the cylinder through the suction valve 6, an air cylinder plunger 4 is erected in the cylinder coaxially with the cylinder, and the axis of the actuating member is An air cylinder chamber 29 is formed on the line, which communicates the inside of the cylinder with the inside of the discharge passage 34 from the discharge valve to the nozzle hole, and the plunger for the air cylinder is placed in the chamber in a watertight manner, and the operation member 17 is placed in a watertight manner.
Due to the vertical movement of the plunger, the plunger relatively moves up and down within the air cylinder chamber, and as the air cylinder chamber becomes narrower and wider due to the vertical movement, outside air can enter and exit the air cylinder chamber through the nozzle hole and the discharge path. A manual sprayer characterized by being fitted with.
