Brush bristles which are distributed in a shape of a cylinder clean residue on tooth surfaces and between tooth gaps in a rotating way. The structure is that the utility model is composed of a handle (1), a press button part (2), a power part (3), a transmission part (4), a protective cover (5) and a brush body (6), wherein, a dry battery (11) is arranged in the brush body (6), the upper end of the negative pole zinc sheet of the battery is contacted with two contacts (12) of the press button part (2), the transmission structure of the transmission part (4) can be the transmission of a harmonic gear, the transmission of a planetary gear or the external engagement of a big and a small gear pairs, and the rotating direction of brush bristles can be converted through the button part (2). The utility model is comfortable to use.

Description

Cylindrical electrical rotary toothbrush

This utility model belongs to household electrical appliance and makes the field, is the special toothbrush that is used to clean human Buccodental.It cleans residue between dental surface and teeth space in rotary manner with the bristle of cylindrical distribution.Because the control of its direction of rotation of softish bristle by button can conversion, add the foaming of toothpaste, it can scrub clean each position and the slot of oral cavity inner teeth gear.

Existing toothbrush is well-known, and its bristle itself is motionless, and the action of brushing teeth is moved by human arm realize fully.The action of this toothbrush generally has dual mode: a kind of is that toothbrush moves up and down at dental surface, and this mode tooth surface of can brushing teeth can be scrubbed the residue between teeth space again.The movement range size is wayward but this mode is brushed teeth up and down, moves bristle big with regard to making gingiva easily and peeling off and hemorrhage.Second kind of teeth brushing way is toothbrush traverse motion on the flank of tooth, and this also is the action that people relatively are accustomed to, and obvious this teeth brushing way is difficult for the residue between slot is scrubbed clean.

The purpose of this utility model is to overcome above-mentioned shortcoming, and the direction of rotation of bristle is consistent with the dental growth direction, and human arm just moves from tooth root portion the bristle that is rotating and gets final product when brushing teeth along the dental growth direction.Obvious this mode has guaranteed that not only bristle do not peel off gingiva, and softish bristle also plays a part massage to gingiva.Be provided with a guard shield in the periphery of bristle non-working surface, its effect has three: one, supports the upper end of brush body, and the one, protection oral cavity inwall and tongue are not bumped by the bristle brush, and the 3rd, guarantee that toothpaste foam does not splash to non-tooth direction, and give full play to the effect of toothpaste.

Implementer's case of the present utility model is: (Fig. 1,2 shows), its structure was by handgrip 1, button section 2, power part 3, driving section 4, guard shield 5 and brush part 6 form, and it is characterized in that Handgrip 1 is made up of end cap 7, O-ring seal 8, spring leaf 9, handle body 10, inner dress The upper end of dry cell 11, its negative pole rolled tin and two contact 12 phases of button section 2 are arranged Contact, button section 2 forms the driving section by interior contact 11, button spindle 13, movable contact 14 4 drive mechanism can be that Harmonic Gears, Planetary Gear Transmission or external toothing are big Pinion is paid, and generator 16 is fixed on the shaft of motor 15, compliant wheel 17 dresses In the endoporus of the casing 18 of driving section 4, guard shield 5 is semicircle letter shape, and the lower end is fixed On casing 18, bearing block 19 is equipped with in the upper end, and brush body 6 is by bristle 20, brush axle 21 structures Become, bristle 20 is arranged by equidistant or helix, is fixed on the brush axle 21, forms circle The column type profile, and the lower end of brush axle 21 is injected in the shaft of compliant wheel 17, its upper end is then Inject in the bearing block 19.

This utility model example: (Fig. 1,2 shows), its structure was made up of handgrip 1, button portion 2, power part 3, driving section 4, guard shield 5 and brush body 6, handgrip 1 is made up of end cap 7, O-ring seal 8, spring leaf 9, handgrip body 10, aneroid battery 11 is equipped with in inside, and the upper end of its negative pole rolled tin contacts with two contacts 12 of button portion 2.Button portion 2 is made up of interior contact 11, button spindle 13, movable contact 14.Change connecing of movable contact 14 and contact 12 or disconnected by moving of button spindle 13, thus the switch and the direction of rotation of control motor 15.Power part 3 is made up of shell and motor 15.The drive mechanism of driving section 4 can be: Harmonic Gears, the big or small gear pair of planetary gear transmission or external toothing.Present embodiment Figure 1 shows that the drive mechanism of harmonic gear, and generator 16 is fixed on the shaft of motor 15, and compliant wheel 17 is contained in the endoporus of driving section 4 casing 18 and rotation.Guard shield 5 is semi-cylindrical shaped, and the lower end is fixed on the casing 18, and bearing block 19 is equipped with in the upper end.Brush body 6 is made of bristle 20, brush axle 21, bristle 20 is arranged by equidistant or helix, be fixed on the brush axle 21, form the column type profile, and the lower end of brush axle 21 is injected in the shaft of compliant wheel 17, its upper end is then injected in the bearing block 19, thereby has realized under the driving of motor 15, is driven the rotation of brush body 6 by driving section 4.

The profile smoothness of column type electrical rotary toothbrush, its color can be diversified, will give cleaning, lucid and lively, smooth, safe sensation, and result of use is good, and is comfortable.
