00:00Until now, I still don't understand why an electric toothbrush costs more than $10.

00:05It turns out that its working principle is so simple.

00:08This is a sonic electric toothbrush that can vibrate 30,000 to 40,000 times per minute.

00:15The same coil at the bottom is used for wireless power supply.

00:19When we put it on the wireless charger, it can be charged because of electronic induction.

00:25Here is the principle of wireless charging.

00:28When a coil has current flowing, move it to the side of another coil.

00:33At this time, the current will flow in the other coil.

00:36Put a battery in it and it can be charged.

00:39This is the principle of wireless charging by electromagnetic induction.

00:43There is a spring on top of the battery.

00:46There are two electromagnets on it.

00:48The direction of the electromagnet's magnetic field will change due to the change in the current direction.

00:55Everyone who has graduated from junior high school knows this.

00:59The control of the current direction is on the PCB board at the back.

01:04The one above is a fixed permanent magnet.

01:07The front magnetic pole is the N pole.

01:10The back is the S pole.

01:13Now, when the electromagnet is energized,

01:16the north and south poles will be generated as shown in the figure.

01:21According to the principle that magnetic poles repel each other,

01:24the principle of one pole attracting the other will cause the toothbrush to vibrate left and right,

01:30and we only need to control the current to change the magnetic poles of the electromagnet,

01:35which will make the toothbrush vibrate continuously.

01:38This vibration is the 30,000 to 40,000 vibrations per minute mentioned above,

01:44which is also the core of the electric toothbrush's ability to clean teeth.

01:48Others are auxiliary functions, such as waterproofing, screen, etc.

01:53Do you think $10 is expensive?
