蓄積されてノズル孔が目塞りすることがあった。The above-described conventional liquid ejector performs suction of outside air for replacement of the ejected liquid by a trigger operation through the ventilation path and the seat.
Press the front and rear ends of the piston against the inner wall of the cylinder,
The air passage and the outside air are provided so as to communicate only when the piston is retracted. However, the inside of the container to which the ejector is mounted may become high in pressure due to a temperature change or the like, and once the discharge valve is opened by the trigger operation from this state, the blockage becomes incomplete, so that the liquid is discharged from the nozzle hole. Leaked. The leakage stops as the pressure in the container decreases due to the leakage, and also ensures that the discharge valve is closed.However, the leaked liquid contaminates the vicinity of the nozzle, and such liquid leakage is repeated. Therefore, every time the liquid was dried, the liquid component was accumulated and the nozzle holes were sometimes clogged.

Trigger 9 that projects forward and is attached to the front of the injection cylinder and hangs down
Piston rod projecting forward from an elastic piston 11 fitted forwardly into the cylinder to the upper rear surface of the cylinder
While engaging the front end face of 12, the lower end into the upper part of the mounting tube, and the piston outer surface opposes at the front end position, the upper end at the lower part of the cylinder wall part that comes off at the rear position, the ventilation path 13 that opens respectively. In the trigger type liquid ejector in which the ventilation path 13 is bored and the ventilation path 13 is blocked by a gas-permeable and water-impermeable water-resistant sheet 14, the rear end of the piston has a larger outer diameter than the inner diameter of the cylinder 5 and the remaining piston. Each of the portions was formed to have a small outer diameter, and the piston rear end portion 11a was pressed against the rear cylinder wall portion of the upper end opening 13b of the ventilation passage 13 in a watertight manner.

外気吸入路とを兼用することとなる。In the state shown in FIG. 1, the injection cylinder 6 is closed by the discharge valve 16 and the air passage 13 is closed by the water-resistant sheet 14, so that even if the container body falls down, liquid leakage is prevented. Absent. Also, if the air inside the container expands due to temperature change, etc.,
Since the water-resistant sheet 14 has air permeability, only the rear end 11a of the piston 11 has an outer diameter larger than the inner diameter of the cylinder 5 and the remaining portion of the piston has an outer diameter smaller than the inner diameter of the cylinder. The air in the container is discharged to the outside of the cylinder through the air passage 13 and the gap between the outer surface of the piston and the inner wall surface of the cylinder because the air in the container is pressure-contacted to the cylinder wall portion rearward from the upper end opening 13b of the air passage 13. Is eliminated. Therefore, the inside of the container does not become so high in pressure, and liquid leakage after the trigger operation due to the high pressure inside the container as in the case of the above-described conventional example can be prevented. Note that the ventilation path 13 also serves as an internal pressure discharge path and an outside air suction path.

The cylinder 5 protrudes forward from the middle of the upright cylinder, and the injection cylinder 6 protrudes forward from the upper end. A nozzle cap 7 is rotatably screwed to the front end of the injection cylinder, and the nozzle hole 8 is opened and closed by the rotation of the cap. On both left and right sides of the front part of the injection cylinder 6, a bifurcated upper end is pivotally connected to cause a trigger 9 to hang down. A projection 10 protruding from the upper rear surface of the trigger is urged forward into the cylinder 5. It is engaged with the front end of a piston rod 12 projecting forward from a resilient piston 11 fitted into the piston rod 12. The lower end and the upper end of the upper part of the mounting cylinder 3 in front of the lower part of the upright cylinder, and the lower part of the cylinder wall portion where the outer surface of the piston 11 faces the front end position and separates from the outer surface of the piston at the rearward movement position. The ventilation path 13 having openings 13a and 13b is formed. The air passage is blocked by a sheet 14 having air permeability, non-water-permeable and water-resistant as in the conventional example described above.

The rear end of the piston was pressed against the rear cylinder wall of the upper end opening 13b of the ventilation passage 13 in a watertight manner. By doing so, the ventilation path 13 passes between the remaining portion of the piston and the inner wall surface of the cylinder and communicates with the outside air.

Since the rear end of the piston is pressed against the rear cylinder wall portion of the upper end opening 13b of the ventilation passage 13 in a watertight manner, the ventilation passage 13 communicates with the outside air through the space between the piston remaining portion and the cylinder inner wall surface, Therefore, even in the distribution stage, the inside of the container does not become high pressure, so that the trigger operation in the high pressure state in the container makes the closing of the discharge valve incomplete,
Therefore, liquid does not leak from the nozzle.
