AI Technical Summary
In existing food waste disposers, the sealing performance at the connection between the motor output shaft and the waste storage bin is poor, which makes it easy for sewage to enter the motor, causing damage and affecting its service life.
A wastewater buffer structure is installed between the motor and the crushing mechanism. By adding a buffer sleeve outside the output shaft and opening a drain hole on its side wall, the distance between the motor and the waste storage box is extended, preventing wastewater from directly entering the motor. The wastewater is collected in the buffer sleeve and discharged in a timely manner.
It effectively prevents sewage from entering the motor, extends the motor's service life, and improves the equipment's reliability and durability.
