Description

 TECHNICAL FIELD

 The utility model relates to a lighter ignition device, in particular to a child-proof lighter piezoelectric ignition device.

 Background technique

 Traditional lighters are direct-ignition type, which can easily cause children to ignite by mistake, causing undesired injury and fire. Manufacturers in some countries have additionally installed various safety locks in lighters, thereby increasing production costs and inconvenience of operation. In order to avoid the CR regulations in some countries, some manufacturers use a high-pressure fire to prevent children from turning on. The ignition pressure reaches 9.5 to 10 pounds, which is very difficult to use.

 Summary of the invention

 The purpose of the present invention is to overcome the above-mentioned shortcomings of existing lighters, and to provide a child-resistant lighter piezoelectric ignition device with high safety and low cost.

 The above object of the present invention is achieved by the following technical solution: a child-proof piezoelectric lighter for turning on a lighter, which includes a conductive energy storage tube and a movement core. A conductive hammer is provided in the conductive energy storage tube, and an impact shaft is provided on the impact hammer. The conductive energy storage tube is in the shape of a circular tube. A guide shaft is provided on the conductive energy storage tube. A movement contacting the conductive energy storage tube is provided with a row groove structure for controlling the operation of the conductive energy storage tube. A pair of rings are provided on the row groove structure. The control line groove and a pair of ignition line grooves, the conductive energy storage tube is located in the line groove structure, and the guide shaft and the impact shaft of the conductive energy storage tube are located in the control line groove and the ignition line groove, respectively.

The annular control groove is composed of an arc-shaped groove and three linear rectilinear grooves, one of which is located at the top of the annular groove and is inclined; "^ j" or ""; the ignition row slot is inverted.

 The invention includes a conductive energy storage tube and a movement core. An impact hammer is provided in the conductive energy storage tube, and an impact shaft is provided on the impact hammer. The conductive energy storage tube is in the shape of a circular tube. A conductive shaft is provided on the conductive energy storage tube to contact the conductive energy storage tube. A movement groove structure for controlling the operation of the conductive energy storage tube is provided on the movement of the movement, and a pair of ring-shaped control grooves and a pair of ignition grooves are provided on the structure. The conductive energy storage tube is located in the structure of the groove. The guide shaft and the impact shaft on the conductive energy storage tube are located in the control row and the ignition row respectively. During ignition, the first step: When the conductive energy storage tube is pressed for the first time, the guide shaft moves down and rotates along one side of the control row groove, that is, the arc row groove. At this time, the impact shaft cannot make the energy storage spring generate energy storage; : Weaken the stress on the conductive energy storage tube. Due to the upward force of the return spring, the guide shaft and the capacity release limit window go up with the impact axis vertically. When going up to midway, the impact axis will release the bottom bevel of the limit window with the capacity. Slide to the energy storage shoulder; Third 歩: At this time, immediately after pressing the conductive energy storage tube again, the guide shaft goes down vertically, and the impact shaft stays on the energy storage shoulder to allow the energy storage spring to store energy. Continue Press the conductive energy storage tube downwards. · When the guide shaft is lowered to the bottom, the upper bevel of the capacity release limit window forces the impact shaft to slide out of the energy storage shoulder. At this moment, the energy storage spring is released instantly, and the impact hammer strikes the bearing nail. High voltage ignition. When the child presses the conductive energy storage tube and releases his hand, during the reset process of the conductive energy storage tube, since the child's operation is simple, the conductive energy storage tube will not be forced to store energy at any time. The entire process will be directly restored by the reset spring. Reached childproof opening.

1. The shape and installation dimensions and installation and use methods of the piezoelectric lighter of the existing lighter are unchanged, and it is applicable to all existing piezoelectric lighters, and has universality;

 2. The production cost is the same as that of the existing lighter piezoelectric ignition device without safety lock, and the production process tooling is unchanged, which is convenient for production management;

3. The ordinary piezoelectric lighter solves the problem of preventing children from opening without adding a safety lock. Holistic, and economical.

 Best embodiment

 As shown in FIG. 1 and FIG. 2, a lighter-proof child-resistant piezoelectric ignition device includes a conductive energy storage tube 1, a slot structure 2, a movement 3, an energy storage spring 5, a capacity release limit window 15, and a guide. Shaft 6, Impact shaft 7, Impact hammer 8, Ring control slot 9, Ignition slot 10, Energy storage shoulder 19, Restoring spring 11, Impact pin 12, Conductive copper sheet 13, Piezoelectric ceramic 14, Discharge copper sheet 16, consisting of copper cap 17 and discharge wire 18. Among them, the control slot 9 in the row slot structure 2 guides the travel of the conductive shaft 6 to drive the capacity release limit window 15 to move to complete the working procedure of the impact shaft 7 between the energy storage shoulder 19 and the ignition row slot 10.

During ignition (see abc d in Fig. 2), the thick and thin lines in the figure are the expanded view of the inner circle of the row slot structure 2, the dashed line is the capacity release limit window 15, and two large and one small circles are respectively guided. Shaft 6 and impact shaft 7), Step 1: When the conductive energy storage tube 1 is pressed for the first time, the guide shaft 6 descends along one side of the control row groove 9 (the impact shaft 7 and the capacity release limit 15 also follow. ) See Fig. 2 (a) to Fig. 2 (b) At this time, striking the shaft 7 cannot cause the energy storage spring 5 to generate energy storage. The second step: weaken the force on the conductive energy storage tube 1, due to the upward force of the return spring 11 , The guide shaft 6 and the capacity release limit window 15 go up with the impact shaft 7, In the situation of FIG. 2 (c), at this time, the impact shaft 7 slides to the energy storage shoulder 19 with the bottom bevel of the release limit window 15; Step 3: At this time, immediately press the conductive energy storage tube 1 again. The guide shaft 6 then vertically descends to FIG. 2 (d), while the impact shaft 7 remains on the energy storage shoulder 19 to store the energy of the energy storage spring 5, and then continues to press down the conductive energy storage tube to make the guide shaft descend to the end. (See Figure 2 (e) The upper bevel of the capacity release limit window 15 forces the impact shaft 7 to slide out of the energy storage shoulder 19 (see the dotted arrow in Figure 2 (d)). At this time, the energy storage spring 5 is released instantly and impacts The hammer 8 hits the receiving nail 12 to produce a high-voltage electric ignition. When the ignition is terminated, as long as the force on the conductive energy storage tube 1 is cancelled, the entire process is restored by the reset spring 11 to the condition before starting.

 When the child mishandles, when the conductive energy storage tube 1 is pressed and the guide shaft 6 descends to FIG. 2 (b), the energy storage tube 1 is released. Since the child's operation is simple, the entire process will change from FIG. 2 (a) to FIG. 2 (b) After Fig. 2 (c) (At this time, the child has no time to force the conductive energy storage tube 1 for the second time), the entire work is directly restored to Fig. 2 (a) by the return spring 11 (that is, the condition before operation). Thereby reaching a childproof opening.

 Industrial applicability

 The invention can be applied to all the existing piezoelectric lighters with the same generality while ensuring that the shape and installation dimensions and installation and use methods of the existing lighter piezoelectric ignition devices are unchanged; The lighter does not need to add a safety lock to solve the child-proof opening. It has economical safety and is suitable for industrial manufacturing.
