Technical Field
The invention relates to the technical field of daily electric appliances, in particular to an electric toothbrush.
Background
Electric toothbrushes have become an important member of the public oral health care at home and abroad. The electric toothbrush mainly uses a motor to vibrate the brush head in high frequency so as to decompose toothpaste into fine foam and deeply clean teeth gaps; and simultaneously, the teeth are rubbed with each other at an overclocking frequency, so that the effects of whitening the teeth and cleaning the oral cavity are achieved. When the pressure of the electric toothbrush is too small during the use process, the cleaning efficiency is low and the cleaning effect is poor. If the pressure of brushing teeth is too high, it is easy to damage the gum. Therefore, control of brushing pressure for electric toothbrushes is important.
When the pressure of the existing electric toothbrush during tooth brushing exceeds a preset value, the motor can rotate to abut against the switch, so that the switch is in a closed state, and the operation of the motor is controlled through the controller, so that the tooth brushing pressure is controlled. However, since the switch contact member of the conventional electric toothbrush is rigidly abutted to the switch, the switch may not be reset when the pressure during brushing is reduced or eliminated, thereby affecting the normal use of the electric toothbrush.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide the electric toothbrush capable of realizing automatic resetting of a switch.
In order to solve the technical problems, the technical scheme of the invention is as follows: an electric toothbrush comprises a first shock pad, a second shock pad, a driving piece bracket, a pressure piece, a battery bracket, a reset elastic piece, a connecting rotating shaft, a bracket cover, a PCB (printed circuit board), a prompter and a switch; the first shock pad and the second shock pad are respectively sleeved at the rear end and the front end of the driving piece, and the driving piece extends into the driving piece bracket; one end of the pressure piece is sleeved at the rear end of the first shock pad, and the other end of the pressure piece is embedded into the circular concave cavity of the battery bracket and is abutted against the battery bracket; the reset elastic piece is arranged at the rear end of the driving piece bracket; the first shock pad, the second shock pad, the driving piece support, the pressure piece and the reset elastic piece form a driving assembly, and the connecting rotating shaft penetrates through the lower part of the driving piece support and the side surface of the battery support and forms a rotating part so as to hinge the driving assembly on the battery support; the bracket cover is arranged above the battery bracket and enables the reset elastic piece to generate elastic deformation; the switch, the prompter and the driving piece are all communicated with the PCB; the switch is arranged at the tail of the driving piece bracket; the driving piece is used for driving the driving assembly to rotate around the rotating part from the initial position to the switch triggering position and enabling the reset elastic piece to generate elastic deformation; in the initial position, the driving piece bracket is separated from the switch, and the switch is in a disconnected state; at the triggering position, the driving piece bracket is abutted with the switch, and the switch is in a closed state; under the elastic deformation force reset action of the reset elastic piece, the driving piece bracket can be driven to rotate to the initial position from the triggering position around the rotating part.
Optionally, the driving assembly is hinged to the battery support through a connecting rotating shaft, the reset elastic piece is fixed to the rear end of the driving piece support, and the support cover is fixed to the battery support and used for enabling the reset elastic piece to elastically deform.
Alternatively, the connection rotation shaft passes through the lower portion of the driving member bracket and the side surface of the battery bracket to form a rotation portion around which the driving member bracket can rotate.
Optionally, one end of the pressure piece is sleeved on the connecting portion arranged at the rear end of the first shock pad, and the other end of the pressure piece is embedded in the circular cavity arranged on the battery support and is abutted against the bottom of the circular cavity, so that the elastic piece is elastically deformed to play roles in positioning, fixing and driving the assembly and damping and silencing.
Optionally, the first shock pad is sleeved at the rear end of the driving part, the first shock pad is clamped between the battery support and the driving part support, and the second shock pad is sleeved at the front end of the driving part.
Optionally, a touch boss corresponding to the switch is arranged on the driving member bracket, and the touch boss is abutted to the switch.
Optionally, the connecting rotating shaft is a shaft rod made of hard materials.
Optionally, the electric toothbrush further comprises a battery, the battery is arranged in the battery support shell, and the battery is used for supplying power to the driving piece, the PCB and the prompter.
Optionally, the prompter is provided with a battery support and the front end of the support cover, the prompter is connected with the PCB, and the PCB is used for controlling the prompter to start when the switch is in a closed state.
Adopt above-mentioned technical scheme, through when the brush head is greater than the setting value to the pressure of tooth, the driving piece can drive assembly and rotate to the trigger position by initial position round the portion of revolving to make and reset the bullet piece and produce deformation. In the triggering position, the triggering boss of the driving bracket is abutted against the switch, and the switch is in an opening state. At the moment, the PCB controls the driving piece to reduce the rotating speed or stop rotating so as to reduce the pressure of the brush head on teeth and open the prompter to remind a user. When the pressure of the brush head on the teeth is reduced or disappears, the elastic deformation force generated by the resetting elastic piece during resetting drives the driving assembly to rotate around the rotating part from the triggering position to the initial position. In the initial position, the touch boss arranged on the driving bracket is separated from the switch, and the switch is in a disconnected state. At the moment, the PCB controls the driving piece to adjust to the original rotating speed, and the prompter is closed. Therefore, compared with the mode that the driving part of the traditional electric toothbrush is in rigid contact with the switch, the electric toothbrush provided by the embodiment of the invention has the advantage that the switch can be automatically reset under the action of the elastic deformation force of the reset elastic piece, so that the normal use of the electric toothbrush is not influenced.
