Abstract

The utility model relates to a safety igniter for protecting children, which comprises a safety button, a sliding block and a compression spring. The safety button is positioned on an abdominal region of a handle and partly protrudes out of the handle; the sliding block is positioned below a piezoelectric device with the outer end pressing against the inner side of the safety button and the end face corresponding to the piezoelectric device is provided with a concaved part; the compression spring presses against the inner side of the safety button. In the normal state, the compression spring forces the sliding block to extend outside and lead the safety button to protrude out of the shell; in addition, the concaved part of the sliding block faces the lower end of the piezoelectric device, when the compression spring is in a normal state. The piezoelectric device can be inversely positioned in the handle. By utilizing different thick places in the sliding block to control the distances of a piezoelectric cap, the utility model can effectively avoids accidental ignition by children as the compression spring can not be totally pressed in the abnormal igniting condition; furthermore, the piezoelectric device is inversely positioned in the shell, which causes no shake between the piezoelectric cap and the piezoelectric body when in use, so the section is not easy to destroy; and as the safety button is positioned on the abdominal region of the handle, the operation can be realized only by the cooperation of fingers apart from the thumb, which is relatively difficult for young children, thus being very safe.
