[0015] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, but should not be construed as limiting the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

[0016] Embodiment 1:

[0017] Please refer to Figures 1-3 , an embodiment provided by the present utility model: An ignition coil includes a magnetic core 1, a first coil bobbin 2 installed on one side of the magnetic core 1, and a second coil bobbin 3 installed on the other side of the magnetic core 1; the structures of the first coil bobbin 2 and the second coil bobbin 3 are the same; wherein, the second coil bobbin 3 includes a primary coil winding area 30 and a secondary coil winding area 31; and terminals 32 are provided on both the primary coil winding area 30 and the secondary coil winding area 31.

[0018] In summary, a primary coil and a secondary coil are both integrated on the magnetic core, thus improving the power of the ignition coil. Furthermore, it solves the problems that when using a straight magnetic bar as an ignition coil in the prior art, more materials are required and the efficiency is low under the same power, as well as the problem of low ignition efficiency in a high-frequency ignition circuit when the primary coil and the secondary coil are separately placed on the magnetic core.

[0019] Furthermore, since the primary coils on the first coil bobbin 2 and the second coil bobbin 3 are connected in series, and the secondary coils on the first coil bobbin 2 and the second coil bobbin 3 are connected in series or in parallel, therefore, by wiring in the above manner, the power of the device is further improved. Specifically, the primary coil and the secondary coil are combined into a unit, and two or more than two such coil units are connected in series on the magnetic core column with a circuit. Thus, by changing the winding method of the high-frequency ignition coil, a more powerful drive circuit and high-voltage ignition output can be achieved. In addition, the secondary coils on the first coil bobbin 2 and the second coil bobbin 3 can also be connected in parallel.

[0020] Based on the above solution, since a partition 33 is provided in the secondary coil winding area 31, and the secondary coil winding area 31 is equally spaced by the partition 33, the secondary coils between multiple strands are isolated from each other, improving the stability of each secondary coil while also enhancing the insulation between each strand of the coil.

[0021] Furthermore, since the magnetic core 1 includes a first part 5 and a second part 6, and the first part 5 and the second part 6 are mutually closed to fix the first coil bobbin 2 and the second coil bobbin 3 on the magnetic core 1, the assembly of each component of the device is simple and convenient, thereby improving the assembly efficiency of the device.

[0022] Embodiment 2:

[0023] Please refer to Figure 4 , an embodiment provided by the present utility model: an ignition coil, including a magnetic core 1 and a third coil bobbin 7 installed outside the magnetic core 1, and a fourth coil bobbin 8 is sleeved outside the third coil bobbin 7. By this means, the power of the ignition coil can also be improved. Among them, the third coil bobbin 7 is the secondary coil and the fourth coil bobbin 8 is the primary coil.

[0024] In addition, the first coil bobbin 2, the second coil bobbin 3, the third coil bobbin 7, and the fourth coil bobbin 8 can be combined on the magnetic core 1 in different ways to make the device have a higher power.

[0025] The specific combination methods are as follows: (1) The first coil bobbin 2 and the second coil bobbin 3 are installed on both sides of the magnetic core 1;

[0026] After combining the third coil bobbin 7 and the fourth coil bobbin 8, that is, the third coil bobbin 7 is sleeved inside the fourth coil bobbin 8; then the combined third coil bobbin 7 and fourth coil bobbin 8 are respectively installed on both sides of the magnetic core 1.

[0027] After sleeving the third coil bobbin 7 inside the fourth coil bobbin 8, install it on one side of the magnetic core 1; then install the third coil bobbin 3 or the second coil bobbin 2 on the other side of the magnetic core 1.

[0028] The above has described in detail the embodiments of the present utility model in conjunction with the accompanying drawings, but the present utility model is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present utility model, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present utility model.
