Claims

[Scope of utility model registration request]

In an automatic sprayer, the injection amount adjustment section for the perfume or deodorant being filled is attached to the upper part of the container via a fixing claw, base, fixing ring, etc., and the injection amount adjustment section is installed in the recess formed above the base. The inner piston is made to protrude slightly, and the injection holes are connected to each other at the bottom, vertically, and upwardly.The inner piston is inserted into the outer piston, which has a slightly smaller diameter at the lower part and has an O-ring fitted. The bottom part of the adjustment part is brought into contact with the head of the adjusting part and inserted into the recess, and both pistons and pistons are kept airtight to cover the cylinder body, and the expansion and contraction force is applied between the upper part of the outer piston and the cylinder body. A large spring is interposed between the upper injection hole and the cylindrical body, and the spring has a small elastic force between the adjustment screw whose lower part protrudes slightly inside the cylindrical body and the bulge of the inner piston. An automatic injection device characterized by intervening.
