The electric toothbrush is composed of a toothbrush handle (9) and a toothbrush head (3); a semicircular casing of the toothbrush head (3) is provided with two toothbrush shafts (1); two lines of toothbrush bristles (2) which are symmetrical are arranged around the toothbrush shafts (1); the lower ends of the toothbrush shafts (1) are provided with toothbrush shaft gears (4); one of the toothbrush shaft gears (4) is directly engaged with a gear of a motor shaft, and the other toothbrush shaft gear (4) is engaged with an intermediate gear (5); the intermediate gear (5) is engaged with a gear (6) of the motor shaft to cause the two toothbrush shaft gears (4) to oppositely rotate in the same speed to drive the two lines of toothbrush bristles (2) to rotate crossedly.
Description
This utility model relates to electric toothbrush, particularly in the electric toothbrushes of the two brush of a kind of suitable brush.
Existing electric toothbrush is the two rolling electric toothbrushes of perpendicular brush, and two round brush direct geareds engagement is because of two brushes roll side by side, limited the length of bristle, influenced the contact surface of brush and tooth, can not clean upper and lower dental bed well during use, more can not the medial surface of tooth have been cleaned preferably.
The purpose of this utility model provides a kind of along the electric toothbrush of the two brush of brush, a brush shaft gear and mesomerism gear engagement are wherein arranged, two brushes are relatively rotated, along brushing teeth bed, and bristle is long, can clean upper and lower dental bed in all directions during use, particularly can be easily the medial surface of tooth be cleaned preferably.
The purpose of this utility model is achieved in that along the electric toothbrush of the two brush of brush to be made up of brush holder and brush two parts, battery and motor are housed in brush holder, the top of brush holder is installed with brush, two brush axles are housed in the housing of brush half garden shape, symmetric two row brush hairs are installed around brush axle, and shaft gear is equipped with in the lower end of brush axle, and one of them brush shaft gear directly meshes with generator shaft gear, another brush shaft gear and mesomerism gear engagement, mesomerism gear meshes with generator shaft gear again.Because two brush shaft gears are identical with the mesomerism gear diameter, so two brushes can be to rotate with fast relative direction is staggered.
This utility model is simple in structure, uses comfortable convenience, and is specious, in light weight portable.
Below in conjunction with accompanying drawing this utility model is described in further detail.
Fig. 1 is a front view of the present utility model.
Fig. 2 is a left view of the present utility model.
Fig. 3 is a profile of the present utility model.
Fig. 4 is circuit theory diagrams of the present utility model.
With reference to Fig. 1, battery (10) and motor (7) are housed in brush holder (9), the outer switch (8) that is equipped with of brush holder (9), the top of brush holder (9) is installed with brush (3), two brush axles (1) are housed in the housing of brush (3) half garden shapes, at brush axle (1) symmetric two row brush hairs (2) are installed on every side, brush shaft gear (4) is equipped with in the lower end of brush axle (1).As shown in Figure 3, direct and generator shaft gear (6) engagement of a brush shaft gear (4), another brush shaft gear (4) and mesomerism gear (5) engagement, mesomerism gear (5) meshes with generator shaft gear (6) again.As shown in Figure 4, connect circuit when switch (8), motor (7) drive generator shaft gear (6) rotates.Generator shaft gear (6) drives brush shaft gear (4) and mesomerism gear (5) rotation that is engaged with, because two brush shaft gears (4) are identical with mesomerism gear (5) diameter, so two brush shaft gears (4) can drive the staggered rotation of two bristles (2) with fast relative direction rotation.
