Abstract: The invention is an igniter gun equipped with a safety mechanism. The invention is characterized in that a lever is provided between a piezoelectric pusher and a trigger, with a first end of the lever pivotally connected to the casing, the second end and middle portion of the lever abutting against the trigger and the piezoelectric pusher respectively; one end of a gas controller is connected with a gas outlet valve, while another end of the gas controller forms a hook that abuts against the first end of the lever, a safety spring which urges the hook to go beyond a movement range of the first end of the lever is set between one side of the gas controller and a casing, a controller switch abutting against a back of the hook is set between another side of the gas controller and the casing, the controller switch is pivotally connected to the casing, and a portion of the controller switch exposed outside the casing.

Abstract: Two hitherto unreported novel hemiterpene glycosides were isolated in substantially pure form from the root of Ilex pubescens. The chemical structures and some properties of these hemiterpenes have been elucidated. These hemiterpene glycosides possess anti-platelet aggregation activity more potent than those of salvianolic acid B and aspirin and may be used in pharmaceutical compositions in humans and mammals in need of such treatment.

Abstract: The invention is an easy-operated igniter gun equipped with a safety mechanism. The invention is characterized in that a strengthener is provided between said piezoelectrics pusher and trigger, with its one end connected axially to the casing, the other end and middle coordinated with the trigger and piezoelectrics pusher respectively; A gas controller is slip-jointed with said gas outlet valve, the head of gas controller forms a hook that may be coordinated with the axially connected end of the strengthener, a safety spring which could force the hook to go beyond the movement range of strengthener axially connected end is set between one side of gas controller and casing, a controller switch propped against the back of hook is set between another side and casing, the controller switch is connected axially to the casing with partial body exposed to outside of casing.

Abstract: The present invention relates to a gas lighter with high-voltage discharge control. In the existing lighter, when an actuator button is pressed, the discharge takes place between the high-voltage electrode and the gas nozzle, thereby the combustible gas is ignited, but such a lighter has unsatisfying safety. The lighter according to the present invention comprises a fuel tank, piezo-electric device and gas outlet device inside the fuel tank, and a windscreen above the gas outlet device. The piezo-electric device comprises a piezo-electric block, an actuator button associated with said piezo-electric block and a conducting wire. One end of the conducting wire is fixed to the piezo-electric block, the other end is fixed to the upper part of the fuel tank as a high-voltage electrode, characterized in that in the windscreen there are a conductor element, which can be brought close to the high-voltage electrode, and a control element connected thereto, said control element is connected to the gas outlet device.
