By setting the main box body, it is convenient to store and stir the applied paint. When in use, floor paint is added through the main paint inlet, and diluent is added into the diluent delivery tube. The drive motor is started to drive the stirring shaft to rotate, so as to mix the diluent and paint. When painting, the control switch can be pressed to open the electric-controlled valve to allow the paint inside the main box body to flow through the outflow pipe to the paint roller of the paint brush assembly.

[0003] The paint for the floor is stirred by a driving motor that drives a stirring shaft inside a storage box.
