Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0024] Example 1
[0025] Please refer to Figures 1-4 This utility model provides an electronic lighter 100, which includes a hollow housing 1, a circuit board 2 housed in the housing 1, a heating wire 3 fixed to one end of the housing 1 and electrically connected to the circuit board 2, a connector 4 fixed to the other end of the housing 1, a USB interface 5 fixed to the end of the connector 4 away from the heating wire 3 and electrically connected to the circuit board 2, and a cap 6 covering the USB interface 5.
[0026] The connector 4 includes a tubular connector body 41 and an annular buckle 42 formed by protruding outward from the outer periphery of the connector body 41. The end of the connector body 41 near the heating wire 3 is inserted into the housing 1 and fixedly connected to the housing 1.
[0027] The cap 6 includes a hollow cap body 61 and an annular groove 62 formed by the inner circumferential recess of the cap body 61. The buckle 42 matches the groove 62. The cap body 61 covers the connector body 41 and the buckle 42 is engaged in the groove 62, so that the cap 6 and the connector body 41 form a detachable fixed connection.
[0028] Specifically, through the cooperative design of the buckle 42 and the slot 62, the electronic lighter 100 does not need to be connected to the cap 6 and the connector 4 by threads, making the electronic lighter 100 more convenient to use and less likely to be lost, and reducing the thread processing process, thus lowering the cost.
[0029] The housing 1 can protect the circuit board 2 and the heating wire 3 and prevent the heat of the heating wire 3 from escaping.
[0030] In this embodiment of the invention, the connector 4 further includes an annular limiting portion 43 extending outward from the outer periphery of the connector body 41. The limiting portion 43 is spaced apart from the buckle 42 and located on the side of the buckle 42 closer to the heating wire 3. The limiting portion 43 is fixedly connected to the housing 1, and one end of the cap 6 abuts against the limiting portion 43. The limiting portion 43 effectively reduces the impact on the housing 1 while the cap 6 covers the USB interface 5, and enhances the stability of the connection between the housing 1 and the connector 4.
[0031] In this embodiment of the invention, the cross-sections of the housing 1, the cap 6, and the connector body 41 are all circular; the limiting part 43 is annular; and the buckle 42 and the slot 62 are both annular. This makes the fixing method of the electronic lighter 100 more stable.
[0032] In this embodiment of the invention, the outer diameter of the limiting part 43 is larger than the outer diameter of the buckle 42.
[0033] In this embodiment of the invention, the outer diameter of the limiting part 43 is the same as the outer diameter of the housing 1, the inner diameter of the cap 6 is smaller than the outer diameter of the buckle 42, and the outer diameter of the cap 6 is equal to the outer diameter of the limiting part 43. Specifically, the difference between the outer diameter of the cap 6 and the outer diameter of the limiting part 43 is very small, which means that the cap 6 can compress the buckle 42 slightly, allowing it to slide within the cap 6 until it slides into the slot 62, at which point the buckle 42 returns to its original shape and engages within the slot 62.
[0034] In this embodiment of the invention, the circuit board 2 is a flexible circuit board.
[0035] In this embodiment of the invention, the end face of the housing 1 away from the cap 6 extends beyond the side of the heating wire 2 away from the cap 6. This better protects the temperature of the heating wire 2 and reduces heat loss from the heating wire 2.
[0036] Compared with existing technologies, the electronic lighter of this invention includes a hollow housing, a circuit board housed within the housing, a heating wire fixed to one end of the housing and electrically connected to the circuit board, a connector fixed to the other end of the housing, a USB interface fixed to the end of the connector away from the heating wire and electrically connected to the circuit board, and a cap covering the USB interface. The connector includes a connector body and a buckle extending outward from the outer periphery of the connector body, with the end of the connector body near the heating wire fixedly connected to the housing. The cap includes a hollow cap body and a groove recessed outward from the inner periphery of the cap body, with the buckle and groove cooperating to fix the cap to the end of the connector body away from the heating wire. This invention effectively improves the user experience of the electronic lighter while reducing manufacturing costs.
