Abstract
A press type lighter having a safety switch includes a clutch structure for controlling the press member and the flow of fuel gas from the liquid gas container to be disposed at a locking or free state. A control member is movably mounted in the receiving chamber of the press member, and has a bottom provided with a leg portion which has a bottom formed with a locking flange rested on a top edge of the liquid gas container. The press member is formed with a locking hole for locking the locking flange of the control member, thereby forming a first-stage safety switch structure by the locking flange and the locking hole, for locking the press member temporarily, so that the press member is locked on the liquid gas container.
Claims7
A press type lighter having a safety switch, comprising:
- a liquid gas container;
- a press member pivotally mounted on the liquid gas container for controlling a flow of fuel gas from the liquid gas container;
- a clutch structure mounted in the press member for controlling which of a locking state and a free state the press member is disposed, the clutch structure including (a) a receiving chamber formed in the press member and having a guide rail formed on an inner wall thereof, (b) a control member movably mounted in the receiving chamber, the control member having a guide plate at an upper end thereof, the guide plate being slidably disposed on the guide rail, the control member having a leg portion extending from a lower side of the guide plate, the leg portion of the control member having a locking flange formed on a bottom end thereof, and (c) a locking hole formed through a lower portion of a wall of the press member for passage therethrough of the locking flange of the control member to rest on a top edge of the liquid gas container, thereby forming a first-stage safety switch structure by the locking flange and the locking hole, so that the press member is locked against pivoting on the liquid gas container;
- a slide knob disposed on an upper side of the guide plate;
- a top cover secured on a top of the press member and having a guide slot formed therein, the slide knob being displaceable within the guide slot to displace the locking flange therewith;
- and,
- a second stage safety switch structure including a locking recess formed in the top cover in open communication with the guide slot, the locking recess and the guide slot together having an L-shaped contour.
