[0008] The cover body is fixedly connected and matched to the open surface of the shell, and the four sides and the bottom surface integrally formed with the shell together form a speed reducer box body with a closed containing cavity, and a terminal end bearing is further fixedly arranged on the cover body.

[0009] Further, the cover body and the shell are fixedly connected by fixed screws, a connecting joint is formed at the connecting position, and the connecting joint and the fixed screws are sealed by sealing glue.

[0010] Further, the transmission shaft is integrally provided with an annular groove at the position matched with the output end bearing, the number of the annular grooves is not less than one, an annular sealing ring is fixedly arranged at the annular groove of the transmission shaft, and the number of the annular sealing rings is not less than one.

[0011] Further, a sealing gasket is arranged at the joint of the motor mounting plane and the side surface of the shell.

[0012] A range hood employs the aforementioned fully sealed oil-proof geared motor.

[0013] In summary, the beneficial effects of this utility model are as follows:

[0014] This product features an integrated annular groove at the mating point between the geared motor drive shaft and the output end bushing. An annular sealing ring is fitted into this groove. Sealant is applied at the joint between the gearbox cover and the housing, as well as at the fixing screws. A sealing gasket is placed at the connection between the motor and the gearbox. These sealing measures prevent oil fumes from seeping into the gearbox and motor from the gap between the output shaft and the oil-impregnated bearing. This eliminates the risk of gear corrosion from oil fumes inside the gearbox and prevents short circuits caused by oil fumes entering the motor, thus extending the service life of the geared motor.
