In order to reduce the length of speed reducer motor, the volume of ice maker is reduced, and L-shaped speed reducer motor is usually used. The speed reducer motor is a power transmission mechanism, which uses the speed converter of gear to reduce the rotation number of motor (motor) to the required rotation number, and obtains the device of larger torque. In the ice making equipment, it connects the key components of motor and ice maker, such as stirring shaft, conveying mechanism, etc. The ice maker is wet due to working environment, and there is a large amount of water vapor and condensed water around. If there is no rustproof water baffle ring, water may enter the inside of speed reducer along the shaft, thereby affecting normal use.

[0003] Chinese utility model patent publication number: CN 212367049 U discloses: a speed reducer box for ice maker, the speed reducer box for ice maker, through setting up the second reinforcing rib, so that the fixed strength of the fourth boss and the cover is higher, and the capacity borne by the output shaft is transmitted to the cover through the output gear, the linkage gear, the linkage shaft, and then transmitted to the fixing frame, so as to further reduce the shaking amplitude of the speed reducer box, reduce the noise during use and prolong the service life. But the speed reducer box for ice maker does not design waterproof structure. When ice is made, the temperature of the screw rod for pushing ice block above the output shaft is very low. When water vapor in the air contacts the surface of the cooler object, water droplets will condense and then drop. When used for a long time, water droplets are easy to drop to the lower part of the screw rod, causing the output shaft and oil seal to be eroded by water, rusting, and shortening the service life of the equipment.
