Description

Technical Field

[0001] This utility model relates to a lighter. Background Technology

[0002] A lighter is a common ignition tool. Its basic structure usually includes a housing, a gas storage device, an ignition device, and a button or dial mechanism for triggering ignition and releasing gas.

[0003] Currently, most piezoelectric lighters on the market use an ignition element that is pivotally connected to the housing via a separate pivot shaft (or pivot). Specifically, shaft holes are typically provided on both side walls of the housing. The pivot shaft passes through a bushing on the ignition element and is then inserted into the shaft holes on both sides, thus rotatably mounting the button to the housing. When the user presses the button, the button rotates around the pivot shaft, which in turn drives an internal mechanism (such as a bridge plate) to simultaneously open the exhaust valve and press the piezoelectric element to generate an electric spark, achieving ignition.

[0004] However, this traditional pivot structure has significant drawbacks: First, the independent pivot is a small, separate component that requires individual handling during production, warehousing, and assembly, increasing material management costs. Second, during assembly, the pivot needs to be precisely aligned and inserted into the button sleeve and housing shaft hole, an operation that is typically cumbersome and time-consuming, unfriendly to automated assembly, and reduces production efficiency. Furthermore, during use, the pivot may detach or wear, affecting product reliability and lifespan. Utility Model Content

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] like Figure 1-7 The lighter shown includes a housing 1, a frame 2, an ignition head 3, a piezoelectric electron 5, and an ignition element 6. The housing 1 contains a gas chamber 7, the gas outlet of which is connected to an exhaust valve 4. The exhaust valve 4 is connected to the ignition head 3, and the ignition head 3 at least partially passes through the frame 2. The wires of the piezoelectric electron 5 extend to the ignition head 3. A bridge plate 8 is oscillatingly mounted inside the housing 1, with its two ends directly or indirectly linked to the exhaust valve 4 and the ignition element 6, respectively. The ignition element 6 includes a rotating part 9 and a lever 10, which together define a clearance opening 11. The rotating part 9 can... The middle frame 2 is rotatably supported on the housing 1; the middle frame 2 passes through the relief opening 11 and is connected to the housing 1, forming an active area 12 between the middle frame 2 and the housing 1, and the rotating part 9 rotates and is confined within the active area 12; the pressing end of the piezoelectric electron 5 is located on the rotation path of the rotating part 9, and when the paddle 10 rotates to the ignition position, it drives the rotating part 9 to press the pressing end of the piezoelectric electron 5. In this application, a ceramic cup 29 is fixed on the middle frame 2, and the ceramic cup 29 is sleeved on the outside of the ignition head 3. The middle frame 2 and the housing 1 can be connected by snap-fit, plug-in or screw.

[0021] In this specification, conventional structures and / or functions already present in this lighter (such as the internal power generation principle of the piezoelectric 5, the sealing method of the gas chamber 7, the specific construction of the exhaust valve 4, etc.) are not described in detail because they are common knowledge to those skilled in the art, and the improvements in this application mainly lie in the pivotal connection structure of the ignition element 6 and its cooperation with the housing 1 and the middle frame 2. This does not mean that the present invention is limited to the details shown, and those skilled in the art can fully implement the complete product design and manufacture based on the prior art and the content of the present invention.

[0022] This application eliminates the need for a traditional independent pivot shaft component. By directly and rotatably supporting the rotating part 9 of the ignition element 6 within the movable area 12 formed by the housing 1 and the middle frame 2, and limiting it with an arc-shaped groove structure, the pivoting structure of the ignition element 6 is greatly simplified. Specifically, the first arc-shaped groove 13 on the housing 1 and the second arc-shaped groove 15 on the arched part 14 of the middle frame 2 cooperate to jointly limit and support the rotating part 9, forming a stable and reliable rotating pair. This structure avoids the problems of detachment and wear that may occur with an independent pivot shaft, ensuring the long-term stability and consistency of the ignition element 6's operation and extending the product's service life. This design effectively avoids the cumbersome process of assembling a small pivot shaft, significantly reducing assembly complexity, improving production efficiency, and facilitating assembly.

[0023] The upper part of the housing 1 is provided with a first arc-shaped groove 13 that matches the shape of the rotating part 9, and the middle frame 2 is provided with an arched part 14. The side of the arched part 14 facing the rotating part 9 is provided with a second arc-shaped groove 15 that matches the shape of the rotating part 9. The first arc-shaped groove 13 and the second arc-shaped groove 15 are arranged opposite to each other and together define the active area 12.

[0024] The rotating part 9 includes a rotating shaft 16 and rotating seats 17 symmetrically fixed at both ends of the rotating shaft 16, and the diameter of the rotating shaft 16 is smaller than that of the rotating seats 17; the two ends of the lever 10 are respectively connected to the rotating seats 17 on both sides; the rotating seats 17 are fitted into the first arc-shaped groove 13 and can rotate therein; the arched part 14 extends between the two rotating seats 17, and its second arc-shaped groove 15 covers and fits against the outer wall of the rotating shaft 16.

[0025] The outer wall of the rotating part 9 is provided with a baffle 18, which is mounted on the pressing end of the piezoelectric electron 5. The housing 1 is provided with a support frame 19, and the middle part of the bridge plate 8 (including the middle left, middle right or center) is mounted on the support frame 19. One end of the bridge plate 8 is engaged with the exhaust valve 4, and the other end extends to the bottom of the baffle 18.

[0026] A flip cover 20 is pivotally connected to the middle frame 2, and the middle frame 2 is provided with a mounting groove 21. The flip cover 20 has a connecting block 22 extending into the mounting groove 21. The connecting block 22 is connected to the two side walls of the mounting groove 21 by a pin 23. A movable gap 24 is formed between the lower end of the connecting block 22 and the bottom wall of the mounting groove 21. The flip cover 20 can rotate relative to the pin 23. In this embodiment, the two sides of the flip cover 20 are provided with a third arc-shaped groove 28 that matches the shape of the rotating part 9.

[0027] In this embodiment, the bottom wall of the mounting groove 21 is provided with a limiting groove 25, and a movable block 26 is provided in the limiting groove 25. A compression spring 27 is connected between the bottom wall of the movable block 26 and the bottom wall of the limiting groove 25. This structure ensures that the flip cover 20 can maintain its open state stably by overcoming the spring force and passing a critical position (passing the stop point) when rotating. If the opening angle does not reach the critical position, the flip cover 20 will automatically close under the combined action of the restoring force of the compression spring 27 and the movable block 26.

[0028] It should be noted that the self-closing function of the flip cover 20 is not limited to the structure described above. For example, a conventional method of setting a torsion spring on the pin 23 can also be used. However, this method is a common design of flip cover 20 structures on the market and is well known to those skilled in the art, and is not the focus of this application's improvement. Therefore, for the purpose of brevity and highlighting the innovation, this application does not elaborate on this common torsion spring structure.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the utility model as defined by the appended claims and their equivalents.
