<p>An aerosol container of the nail gun includes a container body, a valve body (3), a valve core (5), a sealing ring (4) and an elastic piece (8). The upper end of the valve body (3) is flush mounted in the container body. The lower end of the valve body (3) is in tight connection with an inner bag (1). The valve core (5) is installed in the valve body (3). The upper end of the valve core (5) forms a tubular valve nozzle. An inner circumference B and an outer circumference A are manufactured on the upper end of the valve body (3), and the inner circumference B is lower than the outer circumference A. The lower end face of the sealing ring (4) abuts against the upper end of the inner circumference B, and the margin of the sealing ring (4) is contained in the outer circumference A. When the valve core (5) is in the first axial position, the upper necking section C and the lower necking section D is respectively located inside and out side of said boss, and the upper surface and the lower surface of the sealing ring (4) respectively abut closely to the boss and the inner circumference B; when the valve core (5) is in the second axial position, the upper necking section C locates on the opening of the boss, and the upper surface of the sealing ring (4) departs from the lower surface of the boss. Therefore, it's convenient to fill, and it's effective to prevent gas leakage.</p> |
