Gas-powered igniters are mainly various lighters, while electric arc igniters are mainly various electric arc guns and electric arc lighters. These two types of portable igniters use gasoline and batteries as energy sources, respectively. They are all independent functional units, which have the problem of large size and weight, and cannot be carried on airplanes, resulting in waste. Therefore, this utility model proposes a miniature portable electric arc igniter. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0022] like Figures 1-5 As shown, one embodiment of this utility model discloses a miniature portable arc igniter, comprising:
[0023] The housing 1 houses an ignition socket 2, an ignition coil 3, and a circuit board 4. Preferably, the housing 1 has openings at both ends. The ignition socket 2 is fixed to the inner wall of the housing 1 with high-temperature resistant epoxy resin, with one end slightly protruding from one of the openings. The circuit board 4 is fixed inside the housing 1 with screws. An ignition hole 5 is provided on the ignition socket 2. The high-voltage output end of the ignition coil 3 passes through the ignition hole 5 and is exposed outside the housing 1. The circuit board 4 integrates a Type-C interface 6 and an ignition switch 7. The Type-C interface 6 is fixed inside the housing 1, with the interface end protruding from another opening. A through groove is constructed on the housing 1, through which the ignition switch 7 passes and is exposed outside the housing 1. The Type-C interface 6 is located on the outside. The shell 1 is electrically connected to the ignition coil 3 via the circuit board 4 on the side. The Type-C interface 6 supports mainstream charging devices (such as mobile phones and power banks), freeing it from the independent battery limitation of traditional igniters and making it more flexible in use scenarios. When igniting, the Type-C interface 6 is electrically connected to the charging device via a wire to provide DC power. When the ignition switch 7 is pressed, the circuit on the circuit board 4 delivers power to the ignition coil 3. The ignition coil 3 is responsible for converting the input low voltage into the high voltage required to generate an electric arc. The high voltage output terminal of the ignition coil 3 is exposed through the ignition hole 5 and generates an electric arc. The high voltage electric arc is used to ignite the target object. When the ignition switch 7 is released, the electric arc stops.
[0024] In this solution, the igniter is equipped with a circuit board 4 for driving and an ignition coil 3 for generating high voltage. Compared with existing portable igniters, it is smaller and lighter, with a miniature design. It is powered by a universal Type-C interface 6 and does not require a built-in battery or a dedicated charger. This effectively solves the shortcomings of existing portable igniters, expands the market, and improves practicality.
[0025] like Figure 2 As shown, the present invention discloses a further technical solution for the Type-C interface 6. The Type-C interface 6 is a female interface, and the interface direction is set parallel to the side wall of the shell 1. The female interface can be directly connected to a standard Type-C charging cable, and is compatible with most USB PD power supplies (5V / 2A and above). It has strong compatibility. The interface direction is parallel to the side wall of the shell 1, which avoids stress concentration during plugging and unplugging, improves plugging and unplugging life, and thus improves practicality.
[0026] like Figure 4 As shown, the present invention discloses a further technical solution for the ignition coil 3. The ignition coil 3 is a miniature high-frequency step-up transformer. The high frequency of the miniature high-frequency step-up transformer allows the use of smaller ferrite and other high-frequency magnetic core materials and fewer coil turns, thereby achieving significant miniaturization, making it small in size and light in weight. At the same time, it has a fast response, stable output voltage, and can achieve a wider range of voltage conversion ratios, thereby improving its practicality.
[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention discloses a further technical solution for the igniter. The circuit board 4 integrates an indicator light 8, and the housing 1 has a through groove. The indicator light 8 passes through the through groove and is exposed outside the housing 1. By integrating the indicator light 8 on the circuit board 4, the indicator light 8 makes it easier for the user to judge the status of the igniter (such as whether there is a malfunction), thereby improving its practicality.
[0028] like Figure 4 As shown, the present invention discloses a further technical solution for the ignition base 2. The ignition base 2 is made of high-temperature resistant alumina ceramic. The ignition base 2 is made of high-temperature resistant alumina ceramic, which makes the ignition base 2 a ceramic base. It has good high-temperature resistance and insulation, as well as good resistance to electric arc erosion, thereby improving its service life.
[0029] like Figure 4 As shown, the present invention discloses a further technical solution for the ignition base 2. The side of the ignition base 2 away from the outer shell 1 is constructed with an inclined surface and an arc-shaped groove. By constructing an inclined surface on the ignition base 2 and opening an arc-shaped groove on the inclined surface, a physical barrier is formed. When the outer shell 1 is rotated appropriately during ignition, it partially blocks the direct impact of the lateral wind on the ignition flame. This is especially important for outdoor environments or well-ventilated environments, and can significantly improve the reliability of ignition.
[0030] like Figure 1 and Figure 2 As shown, the present invention discloses a further technical solution for the outer shell 1. The outer shell 1 is constructed with an end plate and a through hole 9 is provided through the end plate. By providing the through hole 9, the through hole 9 can be used as a strap hole, and the user can carry it with him by means of a key ring, carabiner or wrist strap, thereby improving its practicality.
[0031] like Figure 1 , Figure 2 and Figure 5 As shown, the present invention discloses a further technical solution for the outer shell 1. The outer shell 1 is tightly fitted with a shell cover 10 at one end near the ignition socket 2. When not in use, the shell cover 10 can be fitted onto the outer shell 1 to cover and hide the ignition socket 2, preventing the ignition socket 2 from being directly exposed to the outside world and avoiding accidental contact with the ignition switch 7, which could lead to the risk of electric shock to the user due to direct exposure of the high-voltage arc. When normal use is required, the shell cover 10 can be removed, thereby improving the protective performance.
[0032] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
