AI Technical Summary

Technical Problem

Lifting devices, particularly in cleaning equipment, are prone to damage when an external force is applied to the raised or lowered object, leading to reduced user experience and device lifespan.

Method used

A lifting device with a protection assembly that disengages from the drive assembly when an external force is applied, utilizing a protective plate and elastic member to prevent hard mechanical contact, ensuring the drive and lifting assemblies remain undamaged.

Benefits of technology

The solution enhances the service life and control accuracy of lifting devices by preventing structural damage, improving user experience through the use of a protection assembly that detaches from the drive assembly under external force.

Abstract

The present application discloses a lifting device and a cleaning appliance, which includes a lifting assembly, a protection assembly, and a drive assembly. In a process of lifting an object using the lifting device, an output end of the drive assembly outputs a driving force through the protection assembly to lift or lower the object via the lifting assembly. After the object is lifted or lowered, if the object is displaced due to an external force, the object applies a force to the protection assembly via the lifting assembly, and the protection assembly is separated from the drive assembly. In this case, no hard mechanical contact occurs between the drive assembly and the lifting assembly, and the structures of the lifting assembly and the drive assembly are not damaged. This improves the service life of the lifting device, improves the control accuracy of the lifting and lowering of the object by the lifting device, and improves the user experience.
