Abstract:
1. An emitter module, comprising: a cartridge; a linkage lever set comprising a first linkage lever, a second linkage lever and a fulcrum, and the fulcrum passes through the first linkage lever and the second linkage lever; a housing providing an accommodation space for retracting the cartridge into a closed position; an actuator for triggering movement of the cartridge into the open position, the actuator comprising a moving part; a retractable latch for retaining the cartridge in the closed position; a mechanical linkage mounted on the moving part of the actuator, the linkage being biased into a cartridge-releasing position that urges the retractable latch into a non-cartridge-retaining position; and wherein when the cartridge is in the closed position, the cartridge is retracted in the accommodation space, and the driver attracts the moving part, and the mechanical linkage mounted thereon, into a position accommodating retraction of the cartridge into the accommodation space.
