Fast detachable automatic cleaning device

Abstract

A fast detachable automatic cleaning device includes a driving assembly and a cleaning assembly. The driving assembly includes a transmission shaft and at least one protrusion block that is a formed integral with the transmission shaft. The cleaning assembly includes a seat, a bearing sleeve connected to the seat, and a cleaning portion surrounding the seat. The bearing sleeve includes an assembly space, at least one track and at least one fixing hole. The driving assembly may be in a simplified structure through the formed integral of the transmission shaft and the protrusion block. Further, the protrusion block may be securely fastened in the fixing hole to enhance the assembly strength of the transmission shaft and the bearing sleeve to solve issues of a complicated structure and insufficient strength of convention solutions.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a fast detachable automatic cleaning device, and particularly to an automatic cleaning device having a simplified structure and reinforced assembly strength.BACKGROUND OF THE INVENTION[0002]Common means for cleaning the floor generally involve tools such as brooms and mops for the cleaning operation. However, with the development of modern technologies, in addition to automatic cleaning tools such as vacuum cleaners and floor cleaning robots in the field of household appliances, there are also large-scale automatic cleaning devices developed for significantly reducing the time needed for cleaning operations. More specifically, for example, the Taiwan Patent No. 1507165 discloses a self-propelled cleaning device including a cleaning member. The cleaning member includes a fixed portion, an extension portion and a cleaning portion. The extension portion extends along an edge of the fixed portion. The cleaning portion includes...

AI Technical Summary

Benefits of technology

The present invention provides a transmission shaft assembly with an improved structure that allows for secure fastening of the protrusion block in the fixing hole, resulting in enhanced assembly strength and solving issues of a complicated structure and insufficient assembly strength of conventional solutions. This is achieved through a simplified structure that includes the transmission shaft and the protrusion block, which is formed as an integral driving assembly.

Problems solved by technology

After using the above self-propelled cleaning device for a period of time, the cleaning member may be contaminated by dirt or damaged, and needs to be replaced or cleaned.

However, it is found from the technical contents of the Taiwan Patent No. 1462716 that, an issue of complicated structure of the driving mechanism is caused as the transmission shaft and the elastic member are separate components.

Thus, when the transmission shaft and the bearing axis undergo multiple assembly processes, the elastic member is prone to elasticity fatigue in a way that the fastening protrusion may fail to become steadily fastened with the fastening recess, hence resulting in an insecure assembly of the transmission shaft and the bearing axis.
