Title: Compound Oral Cleaning Device

Description:
TECHNICAL FIELD OF THE INVENTION 
     The present invention relates to a compound oral cleaning device, and more particularly to a compound oral cleaning device for cleaning slits between teeth and fur on tongue. 
     DESCRIPTION OF THE PRIOR ART 
     Brushing teeth is an important matter for oral cleaning and oral health, and toothbrushes are important tools therefor. Good toothbrushes can make oral cleaning efficiently. Therefore, the market is flooded with all kinds of toothbrushes, divided approximately into traditional toothbrushes and electric toothbrushes. 
     However, as to traditional toothbrushes, a user must use their palm to hold the handle of a toothbrush with their arm being arched, and twitches it back and forth transversely on the surfaces of teeth; this kind of teeth brushing way is a wrong way, always incapable of riding of residues within the slits of teeth therewith, and even worse, causing dental enamel to be damaged seriously. But, the types of the current electric toothbrushes are more numerous; for example, Taiwan Patent No. 1175778 has a quick assembly function, but the toothbrush handle used as a grasping portion is thicker because it must accommodate batteries and a control circuit so that holding it is rather laborious, not conforming to ergonomics especially for children or persons with smaller hands. Moreover, the structure thereof is too complicated, causing the cost to be higher. Taiwan Patent No. 092731 is the same as Taiwan Patent No. 175772 mentioned above in a handing portion; the both of them do not conform to ergonomics, and the structure thereof is too complicated, being inconvenient for use. Therefore, the current electric toothbrushes need to be improved in structure and design. 
     SUMMARY OF THE INVENTION 
     To design a toothbrush handling portion conforming to ergonomics, simplify the structure of a toothbrush, the present invention is proposed. 
     One object of the present invention is to provide a compound oral cleaning device, adapted to clean teeth by means of a rotation thereof, a rotating speed and direction thereof being able to be adjusted, namely, the cleaning device being adjusted to rotate downward when a upper row of teeth are brushed, and adjusted to rotate upward when a lower row of teeth are brushed, thereby achieving the effect of the complete cleaning of slits between teeth, and a toothbrush being able to be replaced with a skin rubbing tool, further having both cuticle removing and skin whitening effects. 
     To obtain the object mentioned above, the present invention proposes a compound oral cleaning device, including: a first main body, at the center of which a control circuit, electric power storage unit and driving element are configured, the control circuit, electric power storage unit and driving element being connected with each other in sequence; and a second main body, coupled to the first main body optionally, a rotating element coupled to the driving element being configured at a center thereof, thereby forming a compound oral cleaning device. 
     Thereupon, the present invention can clean slits between teeth and fur on tongue, and further can carry the replacement of a rotating element, having both cuticle removing and skin whitening effects after being replaced with a skin rubbing tool.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to  FIGS. 1 and 2 , which respectively are an exploded view and perspective view of a compound oral cleaning device according to the present invention, the compound oral cleaning device includes: a first main body  1 , within which a control circuit  11 , electric power storage unit  12  and a driving element  13  in electric connection with each other in sequence are configured; and a second main body  2 , capable of being coupled to the first main body  1  optionally, a rotating element  21  being configured at the center of the second main body  2 , and the rotating element  21  being coupled to the driving element  13 . Furthermore, a charging port  16  in electric connection with the control circuit  11  and electric power storage unit  12  is configured on the bottom of the first main body  1 , and a control button  14  in electric with the control circuit  11  and adapted to control the forward and reverse rotation and rotating speed of the driving element  13  is further configured on the outside of the first main body  1 . Furthermore, the second main body  2  further has a fur cleaning tool  22 , and the rotating element  21  may be a toothbrush or skin rubbing tool. In addition, the driving element  13  may be a speed adjustable reversible motor, torque gear motor, or the like. Furthermore, the first main body  1  further has a display  15  for the observation of a motor rotating speed and forward and reverse rotation direction, where the rotating element  21  may be replaced individually or replaced together with the second main body  2 . Whereby, a compound oral cleaning device can be formed. According to the present invention, slits between teeth and fur on tongue can be cleaned effectively, and the replacement of the rotating element can further be carried out, having both cuticle removing and skin whitening effects after being replace with the skin rubbing tool. 
     Referring to  FIG. 3 , which is a cross-sectional view of a compound oral cleaning device according to the present invention, the rotating element  21  is inserted in the second main body  2  to couple to the driving element  13 , thereby controlling the rotating speed and rotation direction of the rotating element  21  through the control button  14 . 
     Finally, referring to  FIGS. 4 and 5 , which respectively are a schematic view of a compound oral cleaning device according to the present invention upon use and a schematic view of another preferred view thereof, the control button  14  may control the rotating speed and rotation direction of the rotating element  21 ; if a upper row of teeth are brushed, the rotating element  21  is adjusted to rotate upward. On the other hand, if a lower row of teeth are brushed, the rotating element  21  is adjusted to rotate downward. Thereupon, slits between teeth can be cleaned effectively. In addition, the fur cleaning tool  22  is used for the cleaning of fur on tongue. Therefore, according to the present invention, slits between teeth and fur on tongue can be cleaned effectively, and the replacement of the rotating element can further be carried out, having both cuticle removing and skin whitening effects after being replaced with the skin rubbing tool. 
     The present invention has the following advantages: 
     1. the present invention is simple in structure and can save the cost because the coupling of the main bodies to each other by means of tenon; 
     2. the present invention cleans residues in slits between teeth completely because teeth and slits between teeth are cleaned by means of the rotation of the toothbrush; 
     3. the grasping portion of the present invention is of a streamline form, conforming to ergonomics; 
     4. the present invention can control the rotation direction and rotating speed of the toothbrush so that residues between teeth can be cleaned completely; and 
     5. the toothbrush can be replaced with the skin rubbing tool, having both cuticle removing and skin whitening effects
