Below in conjunction with accompanying drawing invention is described in further detail,
Fig. 1 is the longitudinal sectional drawing of a kind of concrete structure of the present invention.
Fig. 2 is the sectional view of Fig. 1 along the A-A line.
With reference to Fig. 1, bonnet (1) and precursor (2) fuse with screw thread.There are two batteries (3) to make two batteries (3) form series connection with crossing connecting plate (4) (making) with elastic copper sheet in bonnet (1) lining.Fixing head (5) top has two boss to be stuck on the precursor (2).There are (7) electrodes of anelectrode (6) (making) and motor to be connected on the fixing head (5) with elastic copper sheet, the negative pole of one of negative electrode (8) (making with elastic copper sheet) and battery (3) is connected, and the other end upwards promotes and the connection of motor (7) electrode by switch (9).Motor (7) is to be placed in the cavity of precursor (2).The little groove that motor (7) front portion has a small boss (10) to be stuck in precursor (2) makes it fixing.Gear (11) on the motor (7) and the internal tooth on the power transmission shaft (12) change (13) interlock, nylon jacket (14) nylon jacket (15) and precursor (2) cast solid.Half garden shape is made in power transmission shaft (12) front, and gear (16) closes its cooperation.With reference to Fig. 2, gear (16) respectively and gear (17), gear (18) interlock, gear (18) again and gear (19) interlock, gear (18) is to be fixed on the precursor with screw axis (20), gear (18) is rotatable.Brush post (21) and brush post (22) respectively and gear (17) gear (19) cast solid.Two screw axis (23) were gone here and there the cavity at brush post (21) brush post (22) center again respectively and were fixed on the preceding part sheath of precursor (2) (24), and brush post (21) brush post (22) is rotatable.Arrange respectively on brush post (21) and the brush post (22) and planting 4 row's hair brooms (25).
When making negative pole, connects pull switch (9), motor (7) rotates, by gear (11) moving internal gear (13) of generation, internal gear (13) passes through power transmission shaft (12) again for moving gear (16), gear (16) is again respectively for moving gear (17) and gear (18), gear (19) also begins to rotate under the effect of gear (18).With reference to Fig. 2, when gear (16) when moving in turn clockwise, brush post (21) and brush post (22) and move in turn with counterclockwise and clockwise both direction respectively.Sheath (24) plays brush post (21) brush post (22) only contact with tooth, no matter brush tooth, lower tooth and tooth inboard like this, total hair broom that keeps is to brush from root along tooth, and the while, another mao broom of brushing on post was scrubbed the tooth front.Bonnet (1), precursor (2), fixed mount (5), switch (9) can be made of plastic.Gear can be made with nylon material.
Claims (2)
1, tooth brushing device of forming by bonnet (1), precursor (2), motor (7), brush post (21) and brush post (22), be characterized in motor (7) power is provided, by the rotation of gear, make and brush post (21) and brush post (22) and rotate simultaneously.
2, by the tooth brushing device of claim 1 regulation, its feature brush post (21) is brushed post (22) with being contained in a sheath (24) lining.
