Specific embodiment

It should be noted that in the case of not conflicting, the embodiment in the utility model and the feature in embodiment can To be mutually combined.

In description of the present utility model it is to be understood that term " " center ", " longitudinal ", " horizontal ", " on ", D score, The orientation of instruction such as "front", "rear", "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outward " or position relationship are Based on orientation shown in the drawings or position relationship, it is for only for ease of description the utility model and simplifies description, rather than instruction Or the hint device of indication or element must have specific orientation, with specific azimuth configuration and operation, be not therefore understood that It is to restriction of the present utility model.Additionally, term " first ", " second " etc. are only used for describing purpose, and it is not intended that indicating Or hint relative importance or the implicit quantity indicating indicated technical characteristic.Thus, " first ", " second " etc. are defined Feature can express or implicitly include one or more this feature.In description of the present utility model, unless separately It is described, " multiple " are meant that two or more.

In description of the present utility model, it should be noted that unless otherwise clearly defined and limited, term " peace Dress ", " being connected ", " connection " should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected, or integratedly Connect；Can be to be mechanically connected or electrically connect；Can be to be joined directly together it is also possible to be indirectly connected to by intermediary, It can be the connection of two element internals.For the ordinary skill in the art, on being understood by concrete condition State concrete meaning in the utility model for the term.

Below in conjunction with the accompanying drawings specific embodiment of the utility model is elaborated.

As shown in figure 1, the utility model is a kind of Laser Igniter, including multiple laser modules 2, laser module 2 is located at In fixture 1, laser module 2 is all to one end emitting parallel light bundle away from fixture 1, the light beam that multiple laser modules 2 send Pool a focus it is preferable that the light beam that sends of multiple laser module 2 is in distance at 10～30mm apart from fixture 1 A focus, this Range Focusing, probability point is pooled, ignition results are high at the 20mm of fixture 1；The power of laser module 2 is 100 arrive 150mW, using low-power laser assembly, low cost；Preferably, the appearance and size of fixture 1 and electrion spark Shape is consistent beyond the Great Wall, is conveniently fixed on equipment, and the structure substituting script is convenient.
