[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0030] It should be noted that all the directionality indications (such as up, down, left, right, front, back, etc.) in the embodiments of the utility model are only used to explain the relative position relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directionality indications also change accordingly.

[0031] As shown in Figure 1 , Figure 2 and Figure 3 , the utility model discloses a gas-electric dual-purpose lighter, which comprises a shell, the shell 100 is composed of a casing and a middle frame, wherein the casing is open at one end to facilitate the installation of other parts, and the middle frame is installed at the opening and closes the casing, a ignition seat is arranged on the middle frame, the ignition seat is a porcelain cup and is fixedly arranged on the middle frame. A gas tank 700, a high-voltage bag 500, a battery 400 and a circuit board 600 are arranged in the shell, wherein the gas tank 700 has a mounting structure and is inserted into the casing to support and fix the high-voltage bag, the battery and the circuit board, wherein the battery and the high-voltage bag are arranged on the left side of the gas tank in sequence, and the circuit board is arranged on the right side of the gas tank.

[0032] A gas outlet valve 710 is arranged on the gas tank 700 and corresponds to the ignition seat 120, and a straight jet tower 130 that communicates with the gas outlet valve is arranged at the ignition seat 120 in the embodiment, the straight jet tower 130 can also adopt a windproof tower, or the tower is not applicable, and the ignition seat is directly communicated with the gas outlet valve to realize open fire. As known in the art, the tower refers to the combination of an atomizer, a mixing chamber and a flame jet nozzle, wherein the straight jet tower is a kind of lighter tower that can make the gas flame in a direct jet mode, so that the gas flame has stronger firepower and higher temperature, and the straight jet tower is a mature accessory in the art and can be directly purchased from the market.

[0033] The high-voltage package 500 has at least two electrode wires, and is oppositely arranged at the ignition seat 120. In the embodiment, four electrode wires are arranged in a quadrangle, and two electric arcs are formed between each two electrode wires, and the electric arcs are arranged in a cross or parallel manner. The above-mentioned arrangement is a conventional arrangement, and thus will not be described in detail.

[0034] The battery 400 is a rechargeable battery, and the power management unit on the circuit board is used to manage the charging and discharging of the battery, so that the battery can be repeatedly used.

[0035] The circuit board 600 is arranged in the casing 100 and is electrically connected with the high-voltage package 500, and is used to control the high-voltage package 500 to generate electric arcs. The circuit board is integrated with corresponding circuits.

[0036] The button 300 is movably arranged on one side of the casing 100. In the embodiment, one end of the button 300 is hingedly connected to the right side of the gas tank, and the button 300 can be moved inward under the action of a force. The inner side of the button 300 is provided with a flap 900 which is linked with the gas outlet valve 710. The button 300 can drive the flap 900 to open or close the gas outlet valve 710 under the action of an external force, and outputs an action instruction. The button 300 is provided with a micro switch 610 on the circuit board 600 for generating an action instruction. The inner side of the button 300 is provided with a first trigger 310 for triggering the micro switch. The inner side of the button 300 is provided with a linkage 320 for driving the flap 900 to move. When the button is pressed and moved inward, the linkage on the inner side of the button presses the flap, so that the flap opens the gas outlet valve. At the same time, the first trigger corresponding to the micro switch also presses the micro switch, so that the micro switch generates an action instruction.

[0037] In order to ensure safety, a safety switch is preferably arranged. The circuit board is powered on by triggering the safety switch, so that the circuit board can be controlled. When the safety switch is cut off, the ignition control cannot be performed, and the safety and reliability are ensured.

[0038] The circuit board 600 has at least two control circuits. The two control circuits can be based on the same single-chip microcomputer, and different instructions and command outputs can be realized through different input pins and output pins. At the same time, the two control circuits are based on the same high-voltage package, so that the cost can be reduced, and the corresponding volume can be smaller.

[0039] The first control circuit controls the high-voltage package 500 to generate a continuous electric arc in response to receiving a specific instruction. The specific instruction includes any one or more of a voice instruction, a gas flow instruction, and a touch signal. In the embodiment, a sound instruction is used to control the continuous electric arc. In this way, the corresponding switch design can be omitted on the casing, and the appearance of the lighter is more beautiful.

[0040] Meanwhile, a microphone 620 for acquiring voice commands is provided on the circuit board 600. In this embodiment, the microphone is located on the inside of the circuit board, while the tactile switch is located on the other side of the circuit board, i.e., the side facing the button. Both can be located on opposite sides of the same position, saving space and making the circuit design more rational. The microphone can directly use a mature module on the market, so it will not be described in detail. Its main control logic is as follows: safety switch triggers - sound is emitted - the circuit board controls the high-voltage transformer to generate a continuous arc. When it is necessary to switch from arc mode to gas mode, the button is pressed - the gas valve is opened - a direct flame is formed, and the arc generation is stopped.

[0041] The second control circuit, in response to receiving the action command from button 300, controls the high-voltage transformer 500 to generate a momentary electric arc. That is, when a continuous electric arc is not needed, the button can be pressed directly to open the gas outlet valve, and the high-voltage transformer generates a momentary electric arc to ignite the gas and form a direct-fire flame. In this case, it is impossible to switch to the continuous electric arc mode.

[0042] In some embodiments, the second control circuit takes priority among the two control circuits. That is, when it receives an action command, it directly switches to the gas ignition mode. After the end of this mode, the special command cannot work and must be retried after the safety switch is reset before it can be used. This can avoid the risk of arcing caused by the special command after the direct flame is used.

[0043] To ensure safety, one end of the button 300 is hinged to one side of the housing 100, and a reset element, which is a spring, is provided between the button and the housing 100. When the button is pressed, the spring is compressed to store energy, and when the force on the button is released, the spring releases energy, causing the button to reset and simultaneously closing the gas valve. This allows the direct jet flame to be shut off directly, achieving a safe and reliable effect. That is, when a direct jet flame is needed, the button is pressed directly, and when it is not needed, it is released, achieving the effect of stopping immediately upon release.

[0044] In this embodiment, one end of the housing 100 is provided with an openable end cover 200. The end cover is rotatably connected to the middle frame, so that the end cover can be opened to expose the ignition socket, or the end cover can be closed so that the ignition socket is stored inside the end cover. A safety switch 800 is provided at the connection between the end cover 200 and the housing 100. The safety switch 800 consists of two parallel metal springs. One of the metal springs can be subjected to force to contact the other metal spring, thereby realizing conduction.

[0045] One end of the end cap 200 is hinged to the housing 100, and the hinged end of the end cap 200 extends downward to form a second trigger 210. A safety switch 800 is correspondingly provided inside the housing 100. The second trigger 210 can trigger the safety switch 800 when the end cap 200 is opened or closed. A deformable spring is provided at the upper end of the gas box. When the end cap is opened, the second trigger will squeeze the spring, causing the spring to form and the two metal springs to contact each other, thereby forming a circuit between the battery and the circuit board.

[0046] One end of the circuit board 600 is provided with a display screen 630 for displaying the number of ignitions, and a display window 110 is provided on one side of the casing. The display window is set in correspondence with the display screen. The circuit board is provided with a counting unit, which generates the number of ignitions by recording the number of two commands and displays it on the display screen. It only displays the total number of the two commands, and can also be used as a power indicator.

[0047] Furthermore, a translucent logo is added to the button, and an indicator light is placed at the corresponding position on the circuit board. The indicator light illuminates the logo to achieve an indication effect. This indicator light is preferably placed near the center of the button; that is, by extending the length of the circuit board, an area for installing the indicator light is formed above the tactile switch.

[0048] In this embodiment, the duration of the continuous electric arc is set to a fixed length, meaning that after a certain period of time, the continuous electric arc can be automatically extinguished, further improving safety.

[0049] The embodiments should not be regarded as limitations on the present invention, but any improvements made based on the spirit of the present invention should be within the protection scope of the present invention.
