发明名称 CLEANING BRUSH STRUCTURE WITH REPLACEABLE BRUSH HAIR PLATE
摘要 The present invention discloses a cleaning brush structure having a replaceable brush hair plate, which comprises an accommodating groove being tapered in width from its front end to its rear end on a plate body of the cleaning brush and a baseboard being tapered in width from its front end to its rear end, such that the baseboard can be secured into the accommodating groove and will not fall out easily. Further, the accommodating groove has an opening disposed above the accommodating groove and slightly smaller than the bottom thereof, and its rear end is broader than its front end, such that when a user takes out the baseboard for replacement or cleaning, the baseboard will not come out uncontrollably due to the excessively applied force.
