Volatile material dispenser and its housing and cartridge

摘要

A volatile material dispenser (100) and its housing and cartridge (600; 700) are disclosed. The housing for the volatile material dispenser (100) comprises a bottom plate (200; 200′), a covering plate (300) and a chamber defined therebetween for receiving a cartridge (600; 700), and the housing further comprises a regulating plate (400) movably mounted to the covering plate (300). The covering plate (300) and the regulating plate (400) each have one bored portion and one non-bore portion. The bored portion (420) and the non-bore portion (410) of the regulating plate (400) each occupy a half of the regulating plate (400). The regulating plate (400) is movable between an open position and a closed position with respect to the covering plate (300). The bored portion (320) of the covering plate (300) is aligned with the bored portion (420) of the regulating plate (400) in the open position, and the bored portion (320) of the covering plate (300) is covered by the non-bore portion (410) of the regulating plate (400) in the closed position. The chamber is provided with a fixing element capable of fixing the cartridge (600; 700) in place. The advantages of the present invention lie in that the dispensing of the dispenser (100) can be controlled more precisely.
