Abstract
An electric toothbrush driven by an eccentric shaft can move upwardly and downwardly with the bristles. The utility model is structurally characterized in that a rotatable driving shaft is arranged in the bristle head, and an eccentric shaft is arranged on the driving shaft; when the eccentric shaft rotates along the driving shaft, the axes of the eccentric shaft oscillates and deflects; the axes of the eccentric shaft deflects for two eccentric distances every time the eccentric shaft rotates for a round, and each round of the rotating accomplishes a circle. Utilizing the principle, the eccentric shaft drives sliding members to reciprocate.
Description
Affiliated technical field:
At present, existing electric toothbrush mainly contains following several mode on the kind of drive: the one, and rotate or rotate by the columniform head toothbrushes of the direct drive of motor through driving columniform head toothbrushes again after the speed change, the 2nd, rotatablely moving of motor exported through being transformed into reciprocating mode after the special mechanism, and drives the plate object swing that is implanted with bristle simultaneously or move back and forth along the brush holder direction.
Background technology:
In above-mentioned electric toothbrush structure, the motion mode that columniform head toothbrushes directly rotates, though it is structurally simpler, but the general volume of brush is bigger, particularly directly the motion mode of rotation easily throws away washings the health that is unfavorable for environment outside the oral cavity, the direction of motion of reciprocating mechanism generally is identical with the direction of brush holder aspect the kind of drive, is unfavorable for not only realizing that bristle reaches the purpose of brushing teeth along teeth space motion, simultaneously also relative complex of its mechanism.
Summary of the invention:
Complicated on the kind of drive in order to overcome existing electric toothbrush, bristle is difficult for realizing the purpose of brushing teeth along teeth space, and the brush rotary movement easily throws away washings and is unfavorable for sanitary defective outside the oral cavity.This utility model provides a kind of eccentric shaft transmission and the easy electric toothbrush that realizes along teeth space motion mode (direction of motion that is bristle is vertical with the brush holder axis direction) of bristle.This kind electric toothbrush not only easily realizes the purpose that bristle is brushed teeth along teeth space, and drive mechanism is simple.
For achieving the above object, the technical solution adopted in the utility model is: power transmission shaft is installed in brush, and power transmission shaft can be around self axis rotation under the power drive of motor.Eccentric shaft is installed on power transmission shaft, it is the distance of e that there are eccentric throw in self axis of eccentric shaft and its gyration axis (that is: the axis of power transmission shaft), like this when eccentric shaft during around the moving circle of its gyration axis (that is: the axis of power transmission shaft) revolution, self axis of eccentric shaft just is offset 2e distance.Two fork plates are installed on lateral symmetry ground in garden outside eccentric shaft, fork plate and slide plate fixed connection (both are an integral body), below the slide plate with vertical two sides of drive shaft axis and brush above the two sides corresponding with slide plate, make the V-type rail of convex-concave antithesis, during beginning between them self strain by material be fastened togather, and make and leave suitable gap between the two, guarantee that slide plate slides swimmingly on the guide rail of V-type.Like this eccentric shaft just can drive fork plate, the moving slide plate of fork strip on brush along the vertical direction reciprocally swinging of power transmission shaft.
The beneficial effects of the utility model are: drive mechanism is simpler, is easy to realize that the vertical direction of bristle and brush holder moves back and forth, and reaches the purpose that bristle is brushed teeth along teeth space.
Description of drawings:
Below in conjunction with accompanying drawing this utility model is described further:
Fig. 1 is a schematic diagram of the present utility model.
Fig. 2 is the I-I cutaway view of Fig. 1
Shown in the figure: 1-brush, 2-slide plate, 3,3A-pitches plate, 4-eccentric shaft, 5-power transmission shaft, 6-coupling, 7-brush holder, 8-output shaft, 9-variator, 10-power shaft, 11-motor, 12-battery, 13-end cap.
The specific embodiment:
In Fig. 1, variator (9), power shaft (10), motor (11), battery (12) are installed in the brush holder (7) successively, and with blanking cover (13) it are enclosed in inner cavity.
Power transmission shaft (5) is installed in brush, and power transmission shaft (5) can be around self axis rotation under the power drive of motor.Eccentric shaft (4) is installed on power transmission shaft (5), it is the distance of e that there are eccentric throw in self axis of eccentric shaft (4) and its gyration axis (that is: power transmission shaft 5 axis), like this when eccentric shaft (4) during around the moving circle of its gyration axis (that is: the axis of power transmission shaft 5) revolution, self axis of eccentric shaft just is offset 2e distance.Two fork plates (3), (3A) are installed in lateral symmetry ground in garden outside eccentric shaft, fork plate (3), (3A) and slide plate (2) fixed connection (both are an integral body), in two sides and brush top with the slide plate corresponding two sides of slide plate (2) below with power transmission shaft (5) axis normal, make the V-type rail of convex-concave antithesis, during beginning between them self strain by material be fastened togather, and make and leave suitable gap between the two, guarantee that slide plate (2) slides swimmingly on the guide rail of V-type.Eccentric shaft (4) just can drive fork plate (3), (3A) like this, and fork plate (3), (3A) drive slide plate (2) and move back and forth along the vertical direction of power transmission shaft (5) on brush (1).
Be the handle shape of elongate at the left end of brush (1), and make clamping apparatus in its end, at the end that brush holder (7) and brush (1) link, make clamping apparatus same antithesis, both are connected by clamping apparatus.Power transmission shaft (5) is connected by adapter (6) with output shaft (8) simultaneously.Thereby realize of the transmission of the power of motor (11) to slide plate (2).
Claims (4)
1, a kind of eccentric shaft transmission and the bristle electric toothbrush that can move up and down, form by brush, slide plate, fork plate, eccentric shaft, power transmission shaft and brush holder, variator, motor etc., it is characterized in that: an end of power transmission shaft (5) is equipped with eccentric shaft (4), and goes into certain distance between the axis of self axis of eccentric shaft (4) and power transmission shaft (5).
2, the electric toothbrush that can move up and down according to claims 1 described a kind of eccentric shaft transmission and bristle, it is characterized in that: fork plate (3) (3A) is fixed connection with slide plate (2), and slide plate (2) and brush (1) at the closed slide of making convex-concave separately relative both sides antithesis, they are by the strain of material self, both are fastened togather, keep suitable gap again between them simultaneously, be beneficial to both relative slips.
3, the electric toothbrush that can move up and down according to claims 1 described a kind of eccentric shaft transmission and bristle, it is characterized in that pitching the shelves fork of opening that plate (3) (3A) forms and ride over the both sides in the outer garden of eccentric shaft (4), and the distance of opening grade is slightly larger than the diameter of eccentric shaft (4).
4, the electronic tooth that can move up and down according to claims 1 described a kind of eccentric shaft transmission and bristle is characterized in that the vibration-direction of slide plate (4) is vertical with the axis direction of brush holder (7) or power transmission shaft (5).
