Abstract

The invention relates to an electric lighter with safety device. It features that a slide sleeve is disposed below a button, and a horizontal slide track and a horizontal slide groove engaged each other and sliding horizontally are disposed between the slide sleeve and the button. It features further that a blind hole is provided in the bottom of the button, and in the blind hole is a spring that enables the button to incline to reset inwardly. One end of the spring is disposed in the blind hole, and the other end is disposed on the slide sleeve. The stroke between the lowest end of the periphery of the button and the position limiting part of the casing aligned with that lowest end is shorter than the minimum stroke required to ignite when the button is in the normal state, so the lighter can not be operated. The lowest end of the button is not aligned with the position limiting part of the casing when the button is pushed rightward, such that the stroke below the lowest end of the button is equal to or larger than the minimum stroke required to ignite, and the lighter can be fired. The invention with said structure has advantages i.e. simple structure, few operation steps and convenient use.

The invention relates to a direct-drive electronic lighter, in particular to an electronic lighter with a safety device and a safety device.

Background technique

The direct-operated electronic lighter in the prior art can be pressed down with a small force, and the blind play of the child is prone to accidents. In addition, it is easy for an adult to automatically ignite due to a mistaken pressing of a button, resulting in an accident. Therefore, various direct-type electronic lighters with safety devices are correspondingly introduced. However, the existing direct-operated electronic lighters with safety devices have a complicated structure and many use steps. Therefore, it is necessary to provide a simple and reliable structure and convenient use. Electronic ignition with safety device is disclosed

SUMMARY OF THE INVENTION An object of the present invention is to provide an electronic lighter with a safety device which is simple, reliable, and convenient to use, and which utilizes the principle of controlling an electronic ignition stroke, in accordance with the deficiencies of the prior art.

The object of the present invention is achieved by the following technical solutions, which comprise an organic shell, a cylinder in the casing and a hood on the casing, an air outlet device installed in the casing, a piezoelectric device, and an air outlet device including an air outlet valve, The piezoelectric device includes a button capable of directly pressing and igniting, a piezoelectric cap and a piezoelectric block, and the bottom end of the button is pressed against the piezoelectric cap, and a sliding sleeve is arranged below the button, and the sliding sleeve is arranged between the sliding sleeve and the button There are horizontal sliding rails and horizontal sliding slots which are horizontally slidable with each other, and a blind hole is opened in the lower part of the button, and a spring which keeps the button inwardly resetting is placed in the blind hole, and one end of the spring abuts in the blind hole, and One end is abutted on the sliding sleeve; when the button is in a natural state, the stroke of the lowermost end of the button to the housing corresponding to the lowermost end is smaller than the minimum stroke required for the electronic ignition, when the button is pushed to the right When the button is at the bottom It is offset from the housing limiting portion so that the lowermost stroke of the button is greater than or equal to the minimum stroke required for the electronic ignition.

After adopting the above structure, since the structure for controlling the electronic ignition stroke is adopted between the button and the casing, when the person hits the fire, the button is directly pressed, since the stroke of the two is smaller than the minimum stroke required for the electronic ignition, the button The lowermost end of the periphery is lowered to the lowermost vertical corresponding housing limit portion, and the ignition cannot be performed; when the button is pushed to the right, the lowermost end of the button is offset from the housing limit portion, so that the lowermost stroke of the button is greater than or It is equal to the minimum stroke required for the electronic ignition. Pressing the button can achieve the stroke required for the fire and smoothly catch the fire. After releasing the hand, the button and the sliding sleeve are returned to the initial state under the return elastic force of the electronic cap, and the button is pressed. Under the action of the spring's returning elasticity, it also returns to the left to the initial test state. In this way, it is possible to prevent the blind play of the child and the accidental pressing of the button by the adult, which causes the accident of the automatic ignition to cause an accident. At the same time, the invention has the advantages of simple structure, less use steps and convenient use.
