Toothbrush

Abstract

A toothbrush is disclosed, in which wing hairs are arranged in a V-shape in left and right sides with respect to the center hairs which are the center toothbrush hairs planted in forward and backward directions in a toothbrush head, and the V-shaped wing hairs of the left and right sides are arranged in a X-shape, and auxiliary hairs are arranged between the forward and backward wing hairs in part of the X-shaped toothbrush hairs. With the above arrangements, a contact surface area of each tooth is widened, and a more effective tooth brushing can be performed in three fossas (mesial fossa (mesial pit), a central fossa (central pit) and a distal fossa (distal pit)), a buccal developmental groove, a lingual developmental groove, an accessory groove, a triangular groove and a buccal groove of a buccal aspect, which correspond to a dental caries portion, an interproximal space in which a food debris might be accumulated, and a contact area peripherals of a buccal aspect in which a food debris might be impacted, so dental caries and tooth diseases (periodontitis) can be advantageously prevented, and a pain due to a temporomandibular disorder and a facial muscle fatigue might be reduced and recovered by protruding a cushion layer from an upper side of a toothbrush.

1 . A toothbrush comprising first and sixth toothbrush hairs that are arranged in parallel in the forward and backward directions with their wing hairs being formed in an X shape with respect to a central hair. 
   
   
       2 . The toothbrush of  claim 1 , wherein said first and sixth toothbrush hairs are configured with each wing hair being formed straight. 
   
   
       3 . The toothbrush of  claim 1 , wherein said first and sixth toothbrush hairs are configured with each wing hair being widened in an outward direction as being formed in a curve shape. 
   
   
       4 . The toothbrush of  claim 1 , wherein said central hair of each wing hair is protruded by 1-2 mm while being formed in a cross shape with its center being formed in a conical shape. 
   
   
       5 . The toothbrush of  claim 4 , wherein said central hair of each wing hair is protruded by 1-2 mm while being formed in a circular shape with its center being formed in a conical shape. 
   
   
       6 . The toothbrush of  claim 4 , wherein said central hairs are arranged at an interval of 2 mm, respectively. 
   
   
       7 . The toothbrush of  claim 1 , wherein the length from a wing hair of a front part of the first toothbrush hair to a wing hair of a rear part of the sixth toothbrush hair is 1.7 cm. 
   
   
       8 . The toothbrush of  claim 1 , wherein said neighboring wing hairs are formed in a diamond shape with their intervals being less than 2 mm. 
   
   
       9 . The toothbrush of  claim 1 , wherein a width between the wing hairs of the front and rear parts of the second and fifth toothbrush hairs is wider than the width of the wing hairs of the front and rear parts of the neighboring toothbrush hairs. 
   
   
       10 . The toothbrush of  claim 1 , wherein said fourth through sixth toothbrush hairs form a line connecting the ends of toothbrush hairs and are configured with their both ends being horizontal and being narrowed with a high inclination to reach a ⅓ portion of the length from a central fossa to buccal and lingual developmental grooves and being sharply inclined toward the center of the central fossa. 
   
   
       11 . The toothbrush of  claim 1 , wherein said first through third toothbrush hairs are configured with their both ends being higher than the center portion in an asymmetrical curve with respect to a ½ portion in one direction based on a central axis. 
   
   
       12 . The toothbrush of  claim 1 , wherein an auxiliary hair of the front part is formed between the wing hairs of the front and rear parts of the second toothbrush hair. 
   
   
       13 . The toothbrush of  claim 12 , wherein said auxiliary hair of the front part has the same height and width as the central portion of the central hair and are spaced apart as much as the width of the central portion of the central hair. 
   
   
       14 . The toothbrush of  claim 1 , wherein an auxiliary hair of the rear part is formed between the wing hairs of the front and rear parts of the fifth toothbrush hair. 
   
   
       15 . The toothbrush of  claim 14 , wherein said auxiliary hair of the rear part is configured with its height being lowered in an outward direction. 
   
   
       16 . The toothbrush of  claim 1 , wherein a barrier wall is protruded between the toothbrush hairs for preventing an inclination of the toothbrush hairs. 
   
   
       17 . The toothbrush of  claim 1 , wherein said toothbrush hair is formed of a plate body. 
   
   
       18 . The toothbrush of  claim 17 , wherein said plate body is formed of rubber or a group of hairs. 
   
   
       19 . A toothbrush, comprising:
 a first cushion layer which is formed on an upper side of a toothbrush head in a dome shape; and   a second cushion layer which is formed on an upper side of the first cushion layer in a band shape and is made of a certain material softer than that of the first cushion layer.
