Stress control brush

Abstract

A stress control brush includes a brush head, an elastic plate and a handle. The brush head includes a bristle seat and a first limit part. The handle includes a holder and a second limit part. The elastic plate connects the brush head and the handle. The elastic plate with curved structure has an unbending type and a collapsed bending type. The first limit part and the second limit part are pressed against each other so as to restrict the bending curvature of the elastic plate.

What is claimed is: 
     
         1 . A stress control brush, comprises:
 a brush head comprising a bristle seat and a first limit part;   a handle comprising a grip and a second limit part; and   an elastic plate interconnecting the brush head and the handle, the elastic plate with a curved structure having an unbending state and a collapsed bending state;   wherein, the first limit part and the second limit part are pressed against each other so as to restrict a bending curvature of the elastic plate at the collapsed bending state.   
     
     
         2 . The stress control brush of  claim 1 , wherein the first limit part is a rib, the second limit part is a block, the rib extends along a direction from the brush head toward the block. 
     
     
         3 . The stress control brush of  claim 1 , further comprising a flexible exterior component made from polymer, the elastic plate being surrounded by the flexible exterior component. 
     
     
         4 . The stress control brush of  claim 1 , wherein the elastic plate further has a first arc side and a second arc side that are opposite to each other, and two straight sides that are opposite to each other, the two straight sides are located between the first arc side and the second arc side, and each of the two straight sides has a notch. 
     
     
         5 . The stress control brush of  claim 1 , wherein the brush head further comprises a plurality of bristles, the bristle seat has a front surface and a back surface that are opposite to each other, the plurality of bristles are set on the front surface, when a first force greater than a first critical force is applied to the brush head along a direction toward the front surface, the elastic plate is at the collapsed bending state. 
     
     
         6 . The stress control brush of  claim 5 , further comprising two covering components, the bristle seat further having two side surfaces located between the front surface and the back surface that are opposite to each other, the two covering components located on the two side surfaces of the bristle seat and extending toward the handle, respectively, the elastic plate located between the two covering components, the elastic plate having a first arc side, a second arc side and two straight sides, the first arc side and the second arc side being opposite to each other, the two straight sides located between the first arc side and the second arc side that are opposite to each other, the two straight sides of the elastic plate covered by the two covering components, respectively. 
     
     
         7 . The stress control brush of  claim 5 , wherein the first limit part is located on the back surface of the bristle seat. 
     
     
         8 . The stress control brush of  claim 5 , wherein the handle further comprises a third limit part, the second limit part and the third limit part are located on two side surfaces of the grip that are opposite to each other, when a second force greater than a second critical force is applied to the brush head along a direction toward the back surface of the bristle seat, the elastic plate is at a collapsed backward-bending state, and the first limit part and the third limit part are pressed against each other so as to restrict the bending curvature of the elastic plate; wherein the first critical force is greater than the second critical force. 
     
     
         9 . The stress control brush of  claim 8 , wherein the first limit part is located on the front surface of the bristle seat. 
     
     
         10 . The stress control brush of  claim 8 , wherein the first limit part comprises a rib and a loop, the second limit part is a block, and the third limit part is a depression, the rib extends along a direction from the brush head toward the block, the loop is located on a terminal of the rib close to the block and surrounding the elastic plate. 
     
     
         11 . A stress control brush, comprising:
 a brush head comprising a bristle seat;   a handle comprising a grip; and   an elastic plate connecting the brush head and the handle, the elastic plate with a curved structure having an unbending state and a collapsed bending state, the elastic plate generating a feedback at the collapsed bending state.   
     
     
         12 . The stress control brush of  claim 11 , wherein a type of the feedback is a force, a sound, a deformation, or a combination thereof. 
     
     
         13 . The stress control brush of  claim 11 , wherein the brush head further comprises a first limit part, the handle further comprises a second limit part, and a bending curvature of the elastic plate is restricted at the collapsed bending state.
