Have you ever wondered how the electric toothbrush you use every day actually works? How does an electric toothbrush clean your teeth? Below Electric Toothbrush Manufacturers-Aiwejay will walk you through how an electric toothbrush works by taking it apart.
Components of an Electric Toothbrush
The components of an electric toothbrush include: the main circuit board, battery, motor, body, wireless charging coil, waterproof O-ring, and drive shaft. Here, we’ll take a closer look at a few of the main components:
As shown in the figure:
Mainboard of an electric toothbrush:
A circuit board consists of a PCB substrate and surface-mount components.
Common PCB substrates include: fiberglass (Xian) boards, bakelite boards, FPC flexible boards, and aluminum-based boards. These types of PCB substrates essentially cover all the circuit board requirements for electric toothbrushes.
Electric Toothbrush Motors:
Since the vibration frequency of a sonic motor is close to the speed of sound, it is called a sonic motor.
The acoustic motor vibrates at a high frequency of 31,000–42,000 times per minute, with a reciprocating angle of ±5°.
Working Principle of a Non-Ultrasonic Hollow-Cup Mechanical Motor:
High-speed rotating motor with a hollow cup; the rotational speed can be selected between 10,000 and 30,000 rpm. the higher the speed, the greater the power consumption, and the shorter the runtime on a full charge. An eccentric wheel is mounted at the top of the motor shaft; as the motor rotates at high speed, the motion is transmitted to the eccentric wheel via the drive shaft, thereby generating random circular vibrations (similar to a cell phone’s vibration).
2. How Electric Toothbrushes Work:
Electric Toothbrush It is an electronic device that uses a charger to fully charge the battery, after which the motherboard chip controls the motor and gear settings via the motherboard.
When you press the power/on button on the electric toothbrush, components inside the handle move to activate a switch on the circuit board. Once this switch is activated, power is drawn from the battery and transmitted through the circuitry to the motor, which then begins to rotate.
When the motor rotates, the cam and gear system converts the high-speed rotational motion generated by the motor into a back-and-forth brushing motion that cleans the teeth.
