[0020] See appendix Figures 1-5This utility model discloses a refillable lighter. The refillable lighter is reusable, more environmentally friendly and economical. It includes a housing 1, an electronic ignition device, and a fuel supply device. The fuel supply device includes a gas tank 21 and a flame nozzle 20. The gas tank 21 is equipped with a gas outlet valve 22 and a filling nozzle 23. The gas outlet valve 22 and the flame nozzle are connected via a gas path assembly. The gas outlet valve 22 is equipped with a lever 24 for controlling its opening and closing. The lever 24 has an operating end 241 that cooperates with the gas outlet valve 22, and a driving end 242. The driving end 242 drives the operating end 241 to control the opening and closing of the gas outlet valve 22 by rotational movement. The operating end 241 pries the gas outlet valve 22 to release gas. The driving end 242 is equipped with an actuating component. The housing 1 has a receiving chamber 11 for accommodating the gas tank 21. The actuating component has a corresponding component in the receiving chamber 11 for pressing the driving end. The pressing end of 242, the housing 1 has an opening 111 leading to the receiving chamber 11 and forming an opening 111 for communication between the receiving chamber 11 and the outside, the air box 21 is detachably configured in the receiving chamber 11 through the opening 111, the air box 21 is positioned and guided by the wall of the receiving chamber 11, the air circuit assembly has an end connector 25 fixedly installed on the housing 1 corresponding to the receiving chamber 11, as a conventional design in the art, the end connector 25 and the flame nozzle 25 can be connected by a hose, the end connector 25 is plugged into and sealed with the air outlet valve 22, and can be detached, the rocker 24 is configured to be restricted on the air box 21 so as to follow the air box 21 in and out of the receiving chamber 11, the air box 21 has a transparent viewing window that allows observation of the air volume in the internal air storage chamber, as a conventional choice, the air box part can be designed with transparent material or the entire air box can be made of transparent material to form a transparent viewing window. The gas box 21 can be removed from the storage compartment 11, allowing the gas volume to be viewed through the visible part of the gas box during use and filling; this facilitates use. Existing gas lighters use a pry-operated gas release valve, a common design. To reduce development costs, a pry bar is used to pry the gas valve for gas release. This design prevents the gas valve from opening during connection to the end connector, thus avoiding gas waste. The pry bar 24 is mounted on the gas box 21, ensuring reliable cooperation between the pry bar and the gas valve. This ensures the pry bar can reliably pry the gas valve for gas release, avoiding unnecessary disassembly and reassembly of the pry bar and gas valve, resulting in a simpler and more compact structure.

[0021] The exhaust valve 22 and the rocker arm 24 are both located on the inner end of the air box 21 along the insertion / extraction direction of the air box 21 into and out of the receiving chamber 11. The end connector 25 is provided with a socket hole, and the exhaust valve 22 has a needle-shaped head 221 that protrudes into the socket hole and forms a detachable connection. The needle-shaped head 221 is sealed with a rubber sealing ring in an annular sealing groove to achieve a seal after insertion; this sealing method has a simple structure; this air box design is beneficial for the insertion / extraction operation of the air box.

[0022] like Figures 2-5 As shown in the figure, in one embodiment of the present invention, the top of the air box 21 is provided with a rocker positioning seat. The rocker positioning seat includes a rocker support protrusion 211 and two oppositely arranged mounting columns 212. An assembly interval is formed between the mounting columns 212. A positioning protrusion 213 is provided in the assembly interval. A positioning interval is formed between the positioning protrusion 213 and the mounting column 212. A limiting shaft 214 is provided on the two mounting columns 212 to block the top opening of the positioning interval. A positioning hole is provided in the middle of the rocker 24. The positioning hole of the rocker 24 is fitted onto the positioning protrusion 213 and limited within the assembly interval by the limiting shaft 214. The rocker 24 is supported on the rocker support protrusion 211.

[0023] For further ease of use, the air box 21 has a grippable end 215 extending out of the opening of the receiving compartment 11, and an inflation nozzle 23 is arranged on the grippable end 215 so that the inflation end of the inflation nozzle 23 is exposed outside the receiving compartment 11. This allows the air box to be inserted and removed by gripping the grippable end, making it more convenient to use, and the exposed inflation nozzle allows for direct inflation without removing the air box, making it more flexible to use.

[0024] To further ensure reliable retention of the air box within the storage compartment and facilitate operation, the housing 1 is equipped with an air box self-locking mechanism that automatically locks the air box 21 after it is inserted into the storage compartment 11. The air box 21 is locked and retained by the air box self-locking mechanism after being placed in the storage compartment 11. Specifically, the air box self-locking mechanism includes a self-locking component 31 that slides on the housing 1 along the direction of insertion and removal of the air box 21. The self-locking component 31 has a locking block 311 and an unlocking end 312. The self-locking component 31 abuts against a self-locking spring 32 that drives the locking block 311 of the self-locking component 31 to the locked position. The air box 21 is provided with a locking groove 216 and a clearance groove 217. The clearance groove 217 extends along the direction of insertion and removal of the air box 21. One end of the clearance groove 217 is a clearance opening that passes through the end of the air box 21. The other end of the clearance groove 217 is laterally connected to the locking groove 216. The clearance opening of the clearance groove 217 is provided with a driving inclined surface 2171 that pushes the locking block 311 to the unlocked position. Pressing the unlocking end 312 drives the locking block 312 of the self-locking component 31 to exit the locked position. Of course, those skilled in the art, under the guidance of this utility model, can also use a cover plate to block the opening of the accommodating compartment to confine the air box within the accommodating compartment, or use magnetic attraction or elastic tight-fitting friction to retain the air box, etc. However, the above design has better reliability and operability, that is, it has the action of pressing the self-locking part to unlock.

[0025] like Figures 1-5 As shown, in one embodiment of this utility model, the design can be integrated with the overall shape, achieving not only a personalized visual design but also improved operability and enhanced product appeal. Specifically, the housing 1 is gun-shaped, with a storage compartment 11 located on the grip portion 1-1 of the housing 1. The opening of the storage compartment 11 is located at the bottom of the grip portion 1-1 on the housing 1. This integration of the air box with the gun-shaped housing facilitates the installation and arrangement of the air box 21. Furthermore, the air box is removable, similar to the "magazine" operation of a gun, adding to the fun. The self-locking mechanism of the air box further enhances the enjoyment of operation.

[0026] To better adapt to the gun-shaped design, the operating components include a trigger 26 and a pressing lever 27 pivotally mounted on the housing 1. The trigger 26, as a commonly used operating component of the gun-shaped lighter, enables ignition by pulling the trigger, satisfying the element of fun. To better achieve the function of ignition by pulling the trigger, the trigger 26 is pivotally mounted on the housing 1. The trigger 26 includes a trigger body 260, on which a pressing arm 261 and a pushing part 262 are formed. The electronic ignition device includes a piezoelectric element 41, with the pressing arm 261 engaging with the piezoelectric element 41. The pressing lever 27 is pivotally mounted on the housing 1 in the middle. The pressing lever 27 includes a driving arm 271 that engages with the pushing part 262, and a driven arm 272 that engages with the rocker arm 24. Figure 3As shown, one end of the rocker arm 24, which slides into the receiving chamber 11 along with the air box 21, corresponds to the corresponding position of the driven arm 272 to form a push-action engagement. Of course, as a feasible solution of this utility model, the trigger can also adopt a sliding design operation mode. In this specific embodiment, the push-action part 262 is a stepped surface provided on both sides of the pressing arm 261, and the driving arm 271 includes two spaced finger arms. The pressing arm 261 is inserted into the gap between the two finger arms, thus realizing the positioning of the trigger and the pressing rocker arm.

[0027] The gas-filled lighter of this utility model has the following advantages: 1. The gas box is designed to be removable and insertable into the housing, and the gas volume of the gas box can be observed; this allows for intuitive judgment of the gas box usage and filling operation, making it more convenient to use; at the same time, the external filling nozzle enables direct filling operation, making it more flexible to use. 2. When the gas box is removed from the receiving compartment, the receiving compartment positions and guides the gas box, and the fixed end connector corresponds to the position of the gas valve, making it convenient to use; the end of the gas box is exposed (i.e., it has a grippable end that extends out of the receiving compartment opening), facilitating the removal and insertion of the gas box, and also allowing the filling nozzle to be exposed. 3. The unique gun-shaped design allows for personalized styling. In addition, the design allows for a reasonable arrangement of the gas box. At the same time, the gas box can become an operable and playable part of the lighter. With the gas box insertion and removal operation, the exposed end of the gas box (i.e., a grippable end that extends out of the storage compartment opening), and / or the gas box self-locking mechanism, a magazine-like operation mode similar to a pistol can be achieved, enhancing the playability.
