[0002] The conductive structure of a lighter typically includes piezoelectric ceramics for discharging, a conductive cup, a gas outlet, an air mixing tube, a rocker arm, and other parts. When the piezoelectric ceramics are discharged by pressing the button, an electric spark will be generated between the conductive cup and the gas outlet to ignite the gas mixture inside the heat-insulating cup.

Alternatively, as described in a lighter gas outlet structure disclosed in application number CN202420944701X, a conductive head is provided on the gas outlet. The conductive head cooperates with the conductive cup to form an electric spark for igniting the gas mixture.

[0004] It is evident that existing conductive structures have a large number of small parts, making assembly complex and ultimately resulting in low assembly efficiency, leaving room for improvement. Utility Model Content

The windproof cover covers the outside of the heat insulation cup, and the gas outlet is located inside the heat insulation cup.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Example 1: As Figures 1 to 3 As shown, a conductive structure for a lighter includes a windproof cover 1, a heat-insulating cup 2, a gas outlet 3, an air mixing tube 4, a piezoelectric ceramic 5, and a rocker arm 6. The windproof cover 1 covers the heat-insulating cup 2, and the gas outlet 3 is located inside the heat-insulating cup 2. At least one conductive element 11 is provided on the windproof cover 1, extending into the heat-insulating cup 2. The distance between the conductive element 11 and the gas outlet 3 is within the ignition distance range. The upper end of the air mixing tube 4 is connected to the gas outlet 3. The rocker arm 6 abuts against the air mixing tube 4 and the piezoelectric ceramic 5 respectively. The wire 51 on the piezoelectric ceramic 5 is directly or indirectly connected to the conductive element 11. A direct connection means that the wire 51 is directly connected to the conductive element 11, while an indirect connection means that the wire 51 is connected to the conductive element 11 through the windproof cover 1.

[0022] In this embodiment, the conductive component 11 is preferably integrally formed with the windproof cover 1 so that it can be processed and formed in one go.

[0023] It should be noted that the wind shield 1, heat insulation cup 2, gas outlet 3, air mixing tube 4, piezoelectric ceramic 5, and rocker 6 are all conventional essential parts of a lighter. This solution, by optimizing the design of the conductive component 11 and the discharge circuit, can eliminate the conductive cup in the traditional structure, simplifying the conductive structure of the lighter and achieving the goal of cost reduction and efficiency improvement. The wind shield 1 used in this solution is preferably made of conductive material so that the wind shield 1 and the conductive component 11 can be processed in one go. The heat insulation cup 2 is preferably made of ceramic cup, and the bottom of the ceramic cup is provided with an installation port. The gas outlet 3 can adopt a pagoda structure or a direct-flow structure.

[0024] When using button 8 (see Figure 6When the piezoelectric ceramic 5 is directly or indirectly pressed to discharge, the piezoelectric ceramic 5, windproof cover 1, conductive component 11, air outlet 3, air mixing pipe 4, and rocker plate 6 form a discharge circuit. This circuit does not contain the conductive cup found in traditional structures.

[0025] Example 2: Figure 2 and Figure 4 As shown, the rest of the parts are the same as in Embodiment 1, except that the upper end of the heat insulation cup 2 is recessed downward to form a relief groove 21, and the middle part of the conductive element 11 is located at the relief groove 21. Preferably, the relief groove 21 extends through the inner and outer sides of the heat insulation cup 2, and the relief groove 21 corresponds to the conductive element 11, so that the conductive element 11 extends into the heat insulation cup 2 with a shorter length.

[0026] Furthermore, the heat insulation cup 2 has an elliptical cross-section, with the clearance groove 21 located at the long axis end of the heat insulation cup 2, and the short axis end of the heat insulation cup 2 abutting against the inner wall of the windproof cover 1. This structural design serves two purposes: first, it facilitates assembly by operators at a specified angle, ensuring that the conductive component 11 aligns with the clearance groove 21 and smoothly extends into the heat insulation cup 2; second, when the short axis end of the heat insulation cup 2 abuts against the inner wall of the windproof cover 1, it prevents the heat insulation cup 2 from rotating during the fire adjustment process, thus avoiding collision damage between the heat insulation cup 2 and the conductive component 11.

[0027] Example 3: Figure 5 As shown, the rest of the parts are the same as in Embodiment 1, except that the conductive element 11 is a conductive needle.

[0028] Example 4: Figure 3 As shown, the rest of the parts are the same as in Embodiment 1, except that the conductive element 11 is a conductive sheet, one end of which is fixedly connected to the windproof cover 1, and the width of the conductive sheet gradually decreases from one end to the other.

[0029] Furthermore, the other end of the conductive sheet is pointed to form a tip discharge head, ensuring that an electric spark is formed at the other end of the conductive sheet, resulting in better stability.

[0030] Example 5: Figures 1 to 3 As shown, the rest of the parts are the same as in Embodiment 1, except that the windproof cover 1 is provided with a flame outlet 12 located directly above the air outlet 3, and the conductive element 11 is located inside the flame outlet 12 or at the lower edge of the flame outlet 12.

[0031] In this embodiment, the conductive element 11 is preferably located at the lower edge of the flame outlet 12, which makes it easier to process and shape, and also allows it to be closer to the inside of the windproof cover 1. In addition, the shorter discharge circuit helps to ensure the response speed.

[0032] Example 6: Figure 6 and Figure 7 As shown, a lighter includes a housing 7, a button 8, a gas tank 9, and the conductive structure of the lighter described in the above embodiment.

[0033] When the piezoelectric ceramic 5 is discharged by pressing the button 8 directly or indirectly, the piezoelectric ceramic 5, the windproof cover 1, the conductive component 11, the gas outlet 3, the air mixing pipe 4, and the rocker 6 form a discharge circuit. At the same time, the rocker 6 rotates and lifts the gasification furnace composed of the air mixing pipe 4, the heat insulation cup 2, and the gas outlet 3 to open the valve of the gas storage tank 9. The gas in the gas storage tank 9 is mixed with air through the air mixing pipe 4 to form a mixed gas. The mixed gas flows into the heat insulation cup 2, and an electric spark is formed between the conductive component 11 and the gas outlet 3 to ignite the mixed gas and form a flame.

[0034] It should be noted that when the rocker arm 6 rotates and lifts the gasifier consisting of the air mixing pipe 4, the insulation cup 2, and the gas outlet 3, the distance between the conductive component 11 and the gas outlet 3 is within the ignition distance range. When the rocker arm 6 is in its initial state without pressing the button 8, the gasifier is not lifted, and the distance between the conductive component 11 and the gas outlet 3 may not be within the ignition distance range. Accordingly, in the design, a clearance of at least the lifting displacement amount is reserved between the bottom of the clearance groove 21 and the conductive component 11 to ensure that the insulation cup 2 and the conductive component 11 do not collide when the gasifier is lifted.

[0035] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the implementation of the present invention is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
