Toothbrush handles main part 131 is formed with at the inner surface of front end area and inserts teat 131a.
131a is formed with a pair of insertion guiding groove 131b along its length at the insertion teat.
Carrier 133 forms the semi-circular section form, is formed with gripper shoe 133a at front end.
Carrier 133 with described structure is bonded in toothbrush handles main part 131 makes gripper shoe 133a cross the inside that insertion teat 131a enters into toothbrush handles main part 131.
Brushhead 150 has brush main part 151, and its upper surface is an essentially rectangular; Toothbrush handles connecting portion 152, it extends to form from brush main part 151.
Brush main part 151 forms the hollow form, has the zone of bristles 163 to be formed with laser irradiation hole 151a in implantation.
Toothbrush handles connecting portion 152 is formed with corresponding to inserting a pair of in conjunction with projection 152a of guiding groove 131b at its outer surface.
Brush 150 with described structure is made by transparent synthetic resin, is combined in toothbrush handles main part 131 with following method.
At first, will be inserted in insertion guiding groove 31b in conjunction with projection 152a.
Then, when passing through to insert guiding groove 131b fully, brushhead 150 is rotated a little in conjunction with projection 152a.
Bonding state between brushhead 150 and the toothbrush handles main part 131 keeps by ending effect in conjunction with the card between projection 152a and the insertion teat 131a.
Laser diode 161 is arranged at the middle section of gripper shoe 133a.
Battery 162 is set up with the mode that a pair of battery terminal 162a that is located at carrier 133 is electrically connected.
Laser Driven portion 170 has substrate 171, and it is loaded into carrier 133; Button 172, it is formed by elastomeric material, and is formed on the middle section of handle main body portion 131; Starting switch 173, it is arranged at carrier 133; Safety switch 174, it is combined in substrate 171; On-off circuit 175 and drive control part 176, it is formed on the substrate 171.
Starting switch 173 has had movable contact and open mode signal generation, play movable contact and when pressing operation button 172, become open mode, when the pressing operation of disengage button 172, become closed condition, the open mode signal generation applies the open mode voltage signal to drive control part 176 when having opened the state of movable contact.
Safety switch 174 is made of cast safety fixed terminal 174a and linear pattern safety movable terminal 174b, safe fixed terminal 174a, and the one end is connected electrically in laser diode 161, safe movable terminal 174b, the one end is connected electrically in on-off circuit portion 175.
