Electric cleaning device

Abstract

An electric cleaning device is provided. The electric cleaning device includes a main body, a power source, a transmission shaft, a support stand, and a plurality of brush heads. The power source is disposed inside the main body. One end of the transmission shaft is connected to the power source, while the other end of the transmission shaft extends out of the main body and is connected to the support stand. The brush heads are flexibly assembled to the support stand and form an enclosed shape. In addition, the power source drives the brush heads to vibrate through the transmission shaft and the support stand.

What is claimed is: 
     
         1 . An electric cleaning device for cleaning a human being's face, the device comprising:
 a main body;   a power source, disposed inside the main body;   a transmission shaft, wherein one end of the transmission shaft is connected to the power source, and the other end of the transmission shaft extends out of the main body;   a support stand, connected to the other end of the transmission shaft; and   a plurality of brush heads, flexibly assembled to the support stand to form an enclosed shape, wherein the power source drives the brush heads to vibrate through the transmission shaft and the support stand, each of the brush heads has a tip, and the tips form a center of the enclosed shape.   
     
     
         2 . The electric cleaning device as claimed in  claim 1 , wherein each of the brush heads comprises:
 a base, assembled to the support stand and keeping a gap from the support stand; and   a plurality of bristles, disposed on the base and located at an opposite side of the support stand.   
     
     
         3 . The electric cleaning device as claimed in  claim 2 , wherein each of the bases has a hook opposite to the bristles, the support stand has a plurality of latching holes, and the hooks are flexibly latched to the corresponding latching holes, so that the brush head is assembled to the support stand. 
     
     
         4 . The electric cleaning device as claimed in  claim 3 , wherein a size of the hook along an assembling direction is greater than a size of the latching hole along the assembling direction, the gap is between the latching hole and the hook, and the assembling direction is parallel to an extending direction of the bristles. 
     
     
         5 . The electric cleaning device as claimed in  claim 3 , wherein each of the latching holes has a profile expanding outward toward the base. 
     
     
         6 . The electric cleaning device as claimed in  claim 3 , wherein the support stand comprises:
 a transmission part, coupled to the other end of the transmission shaft; and   a support part, embedded to the transmission part, wherein the support part has the latching holes.   
     
     
         7 . The electric cleaning device as claimed in  claim 2 , wherein the base is elastic. 
     
     
         8 . The electric cleaning device as claimed in  claim 2 , wherein the base is light-transmissive. 
     
     
         9 . The electric cleaning device as claimed in  claim 2 , further comprising:
 a plurality of light sources, disposed between the main body and the power source, wherein the light sources surround the transmission shaft to provide light that is emitted out of the bristles through the support stand and the base.   
     
     
         10 . The electric cleaning device as claimed in  claim 2 , wherein the main body has a basin-like outer cover toward the brush heads, and each of the bases keeps a distance from a circumference of the basin-like outer cover. 
     
     
         11 . The electric cleaning device as claimed in  claim 2 , comprising a first brush head, a second brush head, and a third brush head, wherein an arc angle of an outer edge of the first brush head is smaller than arc angles of outer edges of the second brush head and the third brush head, and the arc angles of the outer edges of the second brush head and the third brush head are equal to each other and symmetrical to each other with respect to a central axis passing through the center of the enclosed shape. 
     
     
         12 . The electric cleaning device as claimed in  claim 11 , wherein each of the brush heads comprises a plurality of first bristles and a plurality of second bristles, the first bristles are beside the center of the enclosed shape, the second bristles are away from the center of the enclosed shape and surround the first bristles, the first bristles are formed of a light-transmissive material, and the second bristles are formed of an opaque material. 
     
     
         13 . The electric cleaning device as claimed in  claim 11 , wherein a hardness of the bristles disposed on the first brush head is lower than a hardness of the bristles disposed on the second brush head and a hardness of the bristles disposed on the third brush head.
