The brush head anchoring points are disposed between the two springs, the springs being of a “U” shape. Such configuration achieves the perfect fit between the brush head and the housing with a relatively simple structure and strong stability. 
     Advantageously, in one embodiment, the anchoring plate may have multiple holes for fitting purposes. The anchoring plate has multiple positioning points to aid the fit of the brush head with its housing. The brush head assembly will fit into the holes for a perfect fit. 
     In one embodiment, the anchoring plate, the second connecting point, and the limit portion fit together. This second connecting point extends to the back of the anchoring plate in a cylindrical style. The springs are distributed in a circle around the cylinder of the anchoring plate. The housing for the brush head assembly contains perforating points for fitting purposes. There is an outer ring for the brush head, which contains spiral grooves which limits the movement of the brush head when the unit is on and spinning, ensuring that the brush head does not separate from the brush head housing. 
     In one embodiment, a soundproofing o-ring is disposed between the brush head and its outer ring. 
     In one embodiment, there is an outer decorating ring disposed near a front end of the brush head. The decorating ring has grooves for fitting purposes. 
     In one embodiment, the soundproofing o-ring sits in a cavity between the decorating rings and the anchoring plate. The front wall of the soundproofing o-ring is located between the front wall of the decorating ring and grooves in the anchoring plate. The back wall of the soundproofing o-ring sits between the brush head outer ring and the anchoring grooves. 
     In one embodiment, the brush head assembly contains a vibration dampening device. This dampening device sits between the brush head housing and the back wall of the brush head outer ring. 
     This new utility design offers strong advantages and better results when compared to the current existing technology. In particular, this new design features a unique structure that connects the brush head with its housing. It is structurally simple and easy to assemble and install. It also features excellent stability during operation. The smart connecting method utilizes screw type of fitting. This design ensures that the brush head can be small yet offer larger cleaning surface, which improves cleaning efficiency. 
     In order to better explain this new utility design&#39;s structural features and results, device figures and operating instructions may be included. 
     Referring now to  FIGS. 1-8 , various embodiments of the present invention are shown.  FIGS. 1-8  show several advantageous features of the present invention, but, as will be described below, the invention can be provided in several shapes, sizes, combinations of features and components, and varying numbers and functions of the components. In one embodiment, the new design for the facial cleaning brush and the related components includes an outer shell ( 1 ), a brush head assembly, and a motor head. The outer shell ( 1 ) contains a brush head housing ( 2 ) and inside the housing ( 2 ) situates the first connecting point for the motor head.
