Technical Field
The invention relates to the field of toothbrushes, in particular to an electric toothbrush.
Background
When the toothbrush or the electric toothbrush is used, the tooth brushing force of each user is different, but the tooth brushing force is too large, so that the damage to teeth and gums is particularly large. Because the common toothbrush can not provide high-frequency vibration, the cleanness of the oral cavity is ensured completely by the strength of the user, and the damage of tooth brushing to the oral cavity is easy to neglect. When the user changes the common toothbrush into the electric toothbrush, the user can continue the bad habit of using the common toothbrush to the use of the electric toothbrush, and the user uses excessive force to brush teeth to clean the oral cavity, so that the cleaning effect of the electric toothbrush cannot be exerted, and the damage to teeth and gum can be caused.
Disclosure of Invention
Based on the above problems in the prior art, the present invention is directed to a power toothbrush, which can remind a user to adjust the brushing force when the force of using the toothbrush is too high.
The present invention provides an electric toothbrush comprising:
a body formed with a cavity;
a drive unit at least partially disposed in the cavity of the body, a front side of the drive unit being configured to mount a brush head, and the drive unit forming a fulcrum in the cavity, the drive unit being capable of swinging around the fulcrum to both sides of a front and a back of the electric toothbrush, the fulcrum being located at a rear side of the drive unit;
an elastic member provided between the main body and the drive unit and configured to prevent the drive unit from swinging toward a rear surface side of the electric toothbrush;
the first trigger part is used for changing the working state of the driving unit; and
the second trigger part is positioned on the back of the driving unit, the driving unit can trigger the second trigger part to change the state when swinging for a preset amount to the back side, so that the electric toothbrush gives out a prompt about overlarge force, and the second trigger part is positioned between the fulcrum and the elastic part.
Preferably, the electric toothbrush further comprises the brush head, and the brush head, the second trigger part and the elastic member are located on a front side of the fulcrum.
Preferably, a gap is left between the brush head and the main body to allow the brush head to bend relative to the main body.
Preferably, the second triggering portion includes a multi-position switch.
Preferably, the second trigger portion includes a strain gauge, and the drive unit is configured to swing toward the rear surface side to deform the strain gauge.
Preferably, an elastic piece is provided on a rear surface of the drive unit, the drive unit is configured to swing toward the rear surface side to deform the elastic piece, and the strain gauge is connected to a deformation region of the elastic piece.
Preferably, the elastic piece is provided with a projection projecting toward the driving unit.
Preferably, a rib for preventing the driving unit from moving in the left and right directions of the electric toothbrush is protruded in the cavity of the main body.
Preferably, the elastic member has a space between the second trigger and the driving unit.
Preferably, the electric toothbrush further comprises a sealing member filling a gap between the shaft portion of the driving unit and the main body.
Through adopting above-mentioned scheme, when the dynamics of brushing teeth was too big, trigger the second trigger part around the fulcrum to the swing of back side through the drive unit, electric toothbrush sends about the too big warning of dynamics, reminds the user to adjust the dynamics of brushing teeth, forms good habit of brushing teeth.
By replacing different elastic members, the brushing force threshold for triggering the reminder can also be easily adjusted.
