[0013] like Figures 1-4 As shown, a device for ignition based on the principle of light refraction includes a light source component 1 and a focusing component 2. The light source component 1 is provided with a light emitting part 11, and one end of the light source component 1 is provided with a light outlet 12. A switch 13 is provided on the housing of the light source component 1. The switch 13 is used to control the on and off of the light emitting part 11. The specific structure of the light source component 1 can refer to a flashlight, which is a conventional structure of the prior art. The light generated by the light emitting part 11 is emitted from the light outlet 12. One end of the focusing component 2 is fixedly connected to the end of the light source component 1 provided with the light outlet 12. The focusing component 2 can be connected to the light source component 1 by a threaded connection, or by other conventional connection methods. The other end of the focusing component 2 is provided with a focusing outlet 21, and a spherical focusing lens 22 is provided in the focusing component 2. Figure 4 As shown, the spherical focusing lens 22 focuses the light emitted from the light outlet 12 and emits it from the focusing outlet 21, and forms a concentrated point in front of the focusing outlet 21. The light intensity of this concentrated light point is strong, thereby concentrating the energy of the light source and concentrating the heat to achieve the purpose of igniting the object.

[0014] The focusing assembly 2 includes a detachably connected upper shell 23 and a lower shell 24 . In this embodiment, the upper shell 23 and the lower shell 24 are connected by threads. Of course, other conventional connection methods can also be used. The focusing outlet 21 is provided at one end of the upper shell 23 .

[0015] The lower shell 24 is provided with a first chamfered portion 25 , which abuts against a sealing ring 26 . The inner diameter of the sealing ring 26 abuts against the outer wall of the spherical focusing lens 22 . The sealing ring 26 prevents the spherical focusing lens 22 from shaking radially.

[0016] The bottom edge of the light-collecting outlet 21 facing inward is provided with a second chamfered portion 27 , and the spherical focusing lens 22 abuts against the second chamfered portion 27 . The spherical focusing lens 22 is axially fixed by the cooperation between the second chamfered portion 27 and the sealing ring 26 .
