Electronic cigarette lighting device with safety mechanism

Abstract

Disclosed is an electronic cigarette lighting device with a safety mechanism, and the device includes a casing with a combustion-supporting hole formed on the casing, a heat generating unit installed in the casing and alternately positioned with the combustion-supporting hole, and a slide cover installed at the top of the casing and normally covered onto the combustion-supporting hole. After the slide cover is pushed to expose the combustion-supporting hole, the heat generating unit starts generating heat to produce high temperature. A safety mechanism is installed between the casing and the slide cover and capable of blocking the slide cover, such that a user has to release the blocked status of the safety mechanism first before the user can push the slide cover and uses the electronic cigarette lighting device, so that the device can prevent an improper operation of the cigarette lighting device and improve safety.

1 . An electronic cigarette lighting device with a safety mechanism, comprising: a casing with a combustion-supporting hole formed thereon, a heat generating unit installed in the casing and aligned precisely with the combustion-supporting hole, a slide cover slidably installed at the top of the casing and normally covered onto the combustion-supporting hole and including a spring, such that when the slide cover is pushed and slide, the spring is compressed, and the combustion-supporting hole is exposed to let the heat generating unit start generating heat to produce high temperature, and when the pushing force is released, an elastic force of the spring props the slide cover to resume its original position and cover the combustion-supporting hole; characterized in that a safety mechanism is installed between the casing and the slide cover, and the safety mechanism comprises an elastic bracket protruded upwardly from the top of the casing, a window formed on the slide cover and disposed at a position opposite to the elastic bracket, and a press button with the bottom disposed at the top of the elastic bracket and installed onto the window; and at the status when the slide cover covers the combustion-supporting hole, a side edge of the elastic bracket is protruded outwardly from the window, so that the slide cover cannot be pushed or slid since the window is blocked by the elastic bracket, and after the press button is pressed to shift the elastic bracket downward, the blocked status of the slide cover is released, so that the slide cover can be shifted to expose the combustion-supporting hole. 
     
     
         2 . The electronic cigarette lighting device with a safety mechanism according to  claim 1 , wherein the slide cover further includes at least one positioning column downwardly extended from a side of the window, and the press button has a pressing portion with the top protruded upwardly from the window, and at least one positioning plate extended towards the positioning column, and the positioning plate has a positioning hole formed thereon and corresponding to the positioning column for embedding the positioning column, such that the press button can be installed onto the window easily. 
     
     
         3 . The electronic cigarette lighting device with a safety mechanism according to  claim 2 , wherein the casing is formed by engaging a bottom cover with a top cover aligned precisely with the bottom cover and a combustion-supporting hole is formed and reserved on the top cover. 
     
     
         4 . The electronic cigarette lighting device with a safety mechanism according to  claim 2 , wherein the heat generating unit is installed on and electrically coupled to a circuit board, and the circuit board is further electrically coupled to a battery, and the battery is provided for supplying electric power required for the operation of the heat generating unit, and the circuit board is electrically coupled to an electricity charging hole of an external power supply, and the electricity charging hole is exposed from the casing to facilitate accessing a power supply for charging the battery. 
     
     
         5 . The electronic cigarette lighting device with a safety mechanism according to  claim 4 , wherein the circuit board has an electrical conduction area disposed thereon and provided for the battery to supply electric power and allow the heat generating unit to be operated to generate heat, and the slide cover has a through hole formed on a surface of the slide cover and alternately positioned with respect to the combustion-supporting hole, a slide base disposed in the casing and abutted by the spring, and an electrical conducting plate alternately positioned with respect to the electrical conduction area, and when the slide cover is pushed and slid, the slide base is moved synchronously to compress the spring, while the through hole is shifted to a position alternately with respect to the combustion-supporting hole of the casing, so that the heat generating unit is passed through the through hole and exposed from the combustion-supporting hole, and the electrical conducting plate is shifted to a position alternately with respect to the electrical conduction area of the circuit hoard to electrically conduct the electrical conduction area.
