Claims

[Scope of utility model registration request]

The valve housing 1 has a cylindrical wall 11, a bottom wall 12 into which a liquid suction pipe 4 is fitted, and a top wall 14 overhanging a collar 13. It is integrally molded from an elastic material and has a valve chamber 15 formed inside.
3 is tightly fitted to the mouth edge of the container 6 containing the injection solution by the base 5, and a side hole 16 is bored in the front side of the cylinder wall 11.
A guide surface 17 for preventing rotation of the valve rod 2 is formed inside the cylindrical wall 11, and the valve rod 2 has a small diameter hole formed in the axial direction through a front passage 21 and a rear passage 22, each of which has a bottom and is open upward. and a large-diameter base 24 connected to the lower part of the scale part 23, and the peripheral wall of the front passage 21 is connected to the rear passage 22.
The front passage 21 and the rear passage 22 extend upward from the top end of the valve housing to form a nozzle 25 of the front passage 21, and the front passage 21 and the rear passage 22 open toward the front and rear sides, respectively, near the lower surface of the top wall 14 of the valve housing and engage the top wall 14. The base 24 has side holes 26 and 27 that fit together, and the base 24 forms a front groove 29 and a rear groove 30, which will be described below, respectively, together with a sliding surface 28 corresponding to the guide surface 17. A hole is drilled from the top end of the side surface to below the side hole 16 of the valve housing, and a rear groove 30 is bored over the entire length of the rear side surface of the base 24. While fitting into the wall 11, the bottom wall 12
A spring 7 is interposed between the push button 3 and the base 24, and the push button 3 has an injection port 31 on the front side, a vertical hole 32 communicating with the injection port 31 from the top surface, and a cap 33 for opening and closing the vertical hole 32.
The aerosol injection device has a push button 3 inserted into the valve rod 2 so that the nozzle 25 of the valve rod 2 projects into the vertical hole 32 and the rear passage 22 opens into the vertical hole 32.
