Preferably, described brush side within doors is connected with tubular protuberance outer circumference surface, and described brush room is respectively equipped with the strip groove of longitudinal extension up and down on four sidewalls.The left and right sides, described brush room wall is provided with longitudinal extension and the through slot of lateral direction penetrating.Brush can be conveniently installed, be changed in the brush room, and brush chamber within doors is " ten " font substantially, in order to brush is played positioning action.
Preferably, described brush roof section is provided with L shaped lead-in wire fixed leg.Described lead-in wire fixed leg end side is provided with one and picks up the ears.The lead-in wire fixed leg can play fixation to the lead-in wire of brush.
Preferably, described flange portion oral area inner circumferential side is provided with the annular flange flange that a circle protrudes from flange portion oral area end face, and described annular flange flange outer circumference surface is provided with at least three stairstepping boss.
Preferably, described stairstepping boss is provided with two-stage, and the two-stage boss is cuboid, wherein the long-pending height that is first order boss of the height of second level boss and countertop and countertop long-pending 1/5th to 1/3rd.
Preferably, the corresponding described stairstepping boss of described annular flange flange inner peripheral surface is provided with convex tendon.Improve assembling intensity.
Preferably, described convex tendon cross section is isosceles triangle, isosceles trapezoid or protuberance circular arc.
Preferably, described cuboid boss and stairstepping boss are provided with eight.
The utility model with end cap body, brush room in brush carrier by injection moulding integrated molding, both provided cost savings, simultaneously install, more convenient when changing brush.Bearing chamber arranges a plurality of cuboid boss, and bearing chamber and bearing fit face are a plurality of points like this, but not the whole face of cylinder, has improved the degree of assembled of bearing and end cap.The stairstepping boss that same reason, end cap body connect the seam position has improved the degree of assembled of end cap and motor, and comprehensive says, the operating efficiency the when end cap of this structure has improved the mounted motor end cap has on the whole also reduced cost.
