AI Technical Summary

Technical Problem

The door of existing pet feeders relies on its own weight to return to its original position, which can easily lead to incomplete closure and affect the sealing and moisture-proof effect.

Method used

The device adopts a spring-loaded design, with the spring-loaded material integrally molded with the grain bin shell. A guide slope is set at the bottom of the spring-loaded material. The back of the bin door contacts the spring-loaded material and deforms under the pressure of the feeding wheel blades. After the material is discharged, the spring-loaded material returns to its original position, and the bin door closes automatically to ensure that the material is in place.

Benefits of technology

The system achieves automatic closing of the storage door, ensuring a tight seal and moisture protection. The spring sheet design is highly reliable, and damage to a single elastic sheet does not affect the overall function.
