Beschreibung
Zusammenfassung:	The utility model relates to a micro-oil flame detection optical fiber protection device and micro-oil flame detection equipment. The micro-oil flame detection optical fiber protection device comprises an outer tube; the inner tube is coaxially arranged in the outer tube, and the inner tube is used for accommodating an optical fiber; the sleeve is connected to the front end of the inner pipe in a sleeving mode, and the front end of the sleeve is of a necking shape; the lens assembly is used for sleeving the front end part of the optical fiber, and at least part of the lens assembly is located in the sleeve and close to the front end of the sleeve; and the air inlet pipe is communicated with the inner pipe and the space between the inner pipe and the outer pipe. The design at least has the following advantages: the lens assembly can protect and focus the end part of the optical fiber; the inner pipe is close to the lens assembly, and the opening end of the inner pipe is set to be in a necking shape, so that co
