Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
The utility model implementation method discloses a kind of hand-held fire-fighting thermal imaging system.Referring to Fig. 1, Fig. 1 is the utility model reality
Apply a kind of structure chart of the hand-held fire-fighting thermal imaging system of example.
