Abstract

The utility model discloses a high-efficient low-consumption electric toothbrush, and the brushing pressure of the electric toothbrush can be controlled within an appropriate range. The tooth brushing pressure controls the action of a switch through a tooth brushing pressure measure and control mechanism which is formed by a force measuring lever which is composed of a toothbrush head body (1), a toothbrush head rod (2), a supporting shaft (4) and a spring (10); when the pressure is within a limited range, a switch (9) is closed, and the toothbrush works; a toothbrush head is composed of eccentric wheels (14) and toothbrush bristle bodies (15) of equal quantity; when the quantity is larger than one, an angle differs between the eccentric wheels. During tooth brushing, the eccentric wheels drive the toothbrush bristle bodies to swing left and right and move relatively to clean teeth.

Description

Electric toothbrush

This utility model relates to a kind of electric toothbrush, specifically a kind of electric toothbrush of being made up of the housing of brush, drive mechanism, motor, switch, battery and double as brush holder.

The toothbrushing force of commercially available electric toothbrush can not be controlled, and exists low, the weak effect of the too little clean rate of pressure, the shortcoming of the too big easy damaged gingiva of pressure, and switch also all is manual, thereby uses inconvenience.The Jordan* that Philip (PHLIPS) company produces is electronic to protect toothbrush had increased and crosses toothbrushing force and limit mechanism, that is: when toothbrushing force is excessive, and the switch automatic disconnection, toothbrush is not worked.This toothbrush has only been done qualification to pressure, and fail toothbrushing force is controlled in the suitable scope, more can not require reasonable controlled pressure scope according to dissimilar people's different toothbrushing forces, and that its switch is still is manual, simultaneously, the shortcoming that this toothbrush also exists complex structure, manufacturing cost height, volume is big and power consumption is many.

The purpose of this utility model is that a kind of toothbrushing force of design can be controlled in the electric toothbrush in the OK range, also have simultaneously simple in structure, volume is little, power consumption is few, clean rate is high, easy to use and adapt to wide characteristics.

The purpose of this utility model adopts following solution to realize: also have a toothbrushing force observing and controlling mechanism at brush and switch room, bristle passes through this mechanism controls switch motion to the toothbrushing force of the flank of tooth on the brush, when toothbrushing force during greater than the unlatching value and less than limit value, switch closure, toothbrush work; When toothbrushing force during less than the unlatching value or greater than limit value, switch disconnects, and toothbrush is not worked; The unlatching value is less than limit value.

Brush of the present utility model is formed by being installed in body brush on the brush body, bolster, eccentric, power transmission shaft etc.The eccentric and the body brush that have quantity to equate on the brush, body brush is equipped with bristle, and eccentric is installed on the power transmission shaft, and power transmission shaft links to each other with motor by drive mechanism, and when motor rotated, eccentric drove corresponding body brush and swings cleaning teeth around bolster.

In above-mentioned solution, because the switch of electric toothbrush is by toothbrushing force control automatically, only in suitable toothbrushing force scope, toothbrush is just worked, solve the shortcoming that existing electric toothbrush toothbrushing force can not be controlled, switch need be manual, had Anti-dental injury gum, easy to use, flexible characteristic; Adopt the brush of this solution design, have characteristics simple in structure, that volume is little, power consumption is few, clean rate is high; This solution also is easy to according to dissimilar people the difference of toothbrushing force, brush size be required flexible design, thereby adapts to wide.

Embodiment below in conjunction with accompanying drawing is described in further detail this utility model:

Fig. 1 is the structure chart of this utility model embodiment;

Fig. 2 is the A-A cutaway view of Fig. 1;

In Fig. 1 and Fig. 2, brush body (1) is connected one as the arm of force with brush bar (2), support (3) is positioned on the housing (7), on fulcrum (4) is housed as fulcrum, between support (3) and brush bar (2) spring (10) is housed, toothbrushing force observing and controlling mechanism is made up of the dynamometry lever that brush body (1), brush bar (2), fulcrum (4) and spring (10) constitute; Pressure switch (9) is contained on the support (3), and body brush (15), eccentric (14), bolster (13) and power transmission shaft (12) are housed on the brush body (1); Pressure switch (9) and battery (6), motor (5) connected in electrical series connect; When brushing teeth, bristle is passed to pressure switch (9) to the pressure of the flank of tooth by body brush (15), bolster (13), brush body (1), brush bar (2), when toothbrushing force during greater than the unlatching value and less than limit value, and pressure switch (9) closure, toothbrush work; When toothbrushing force during less than the unlatching value or greater than limit value, pressure switch (9) disconnects, and toothbrush is not worked.The unlatching value is greater than 10 grams, and limit value specifically can be determined by dissimilar (as: child, child, Ms, man etc.) people's reasonable toothbrushing force less than 400 grams.

Brush body (1) is equipped with eccentric (14) and the body brush (15) that quantity equates, body brush (15) is equipped with bristle, and eccentric (14) is around power transmission shaft (12) rotation, and body brush (15) is swung around bolster (13); The quantity of eccentric (14) and body brush (15) can be 1, also can be greater than 1, when greater than 1 the time, differing an angle (best angle is 90 °) between each eccentric (14) is installed on the power transmission shaft (12), power transmission shaft (12) is by shaft coupling (11), drive mechanism (8) links with motor (5), when motor rotates, eccentric (14) drives corresponding body brush (15) and swings around bolster (13), simultaneously owing to differ 90 ° between the eccentric (14), make it also to produce relative motion between corresponding body brush (15), and it is stressed when maximum to have eccentric, another is the characteristics of stressed minimum then, make the motor stress equalization, operate steadily.

The used battery (6) of this utility model can be aneroid battery, rechargeable battery, also can replace with alternating current steady voltage plug.

Claims

1, a kind of housing by removable brush, drive mechanism, motor, switch, battery and double as brush holder is formed, and had an electric toothbrush that toothbrushing force limits mechanism, it is characterized in that: also have a toothbrushing force observing and controlling mechanism at brush and switch room, bristle passes through this mechanism controls switch motion to the toothbrushing force of the flank of tooth on the brush.
