Type-C Wired charging: Convenient choice As an early work in the electric toothbrush market, Type-C wired charging method has become the first choice of many brands with its versatility. The popularity of Type-C interface makes it easy for both new and old users to find suitable charging equipment and realize seamless charging connection.
Doctor U type toothbrush good Doctor U type toothbrush price is not expensive is more than 100, but the effect is really good, this toothbrush is smart sonic electric toothbrush, children themselves into the mouth, press the button, leftThe right shake can complete the brushing, and there is a timing function, do not worry about brushing time is insufficient or too long, 45 seconds the toothbrush will stop itself. After teaching the baby once, I can brush my own teeth.
usmile Y1 This toothbrush vibration frequency 38000 times/minute, toothbrush has three modes: cleaning, whitening, care, its vibration intensity corresponding to: medium, strong, weak, you can continue to press the switch after opening three modes, each mode has LED indicator to distinguish, very eye-catching.
Dr. Power electric toothbrush is characterized by the use of magnetic suspensionFloating sound motor, with magnetic suspension constant motion patent technology, powerful power, can convert toothpaste and water into countless micro-bubbles, clean the entire mouth without dead corners, and effectively remove dental plaque and tartar. There is also a non-slip design, the hand part is very textured, looks very comfortable. The simple electric toothbrush is characterized by a simple one-click switch of three modes: clean, sensitive, clean and white.
OK. The quality of Dr. Ma electric toothbrush is very good, the shape design style is very lovely, the bristles are delicate and soft, designed for the baby's mouth, practical, soft and comfortable and mouth protection. The price of the toothbrush is between 100 yuan and 300 yuan, which is affordable and deeply lovedTo meet the charging and use needs of various devices. DC15V is widely used in various electronic devices.
2, DC-15V refers to the DC voltage at 15 volts of the power supply. This power supply is usually widely used in entertainment equipment, network equipment, security equipment and other fields. Its working principle is to control and convert the AC power supply through transformers, capacitors, voltage regulating circuits and other devices to ensure the stability and reliability of the output voltage. DC-15V power supply has many advantages, such as safety and reliability, good voltage stability, high energy conversion efficiency.
3, marked next to the power supplyDC15V, which means 15 volts DC.
Wireless charging PCB, different functions, the required components are different. The required components are: resistor, capacitor, resonant capacitor, resonant coil, MOS tube, control chip, protocol chip.
The realization of wireless charging function requires a wireless transmitter module and a receiving module, which are now on the marketThe new mobile phones launched by major mobile phone brands have built-in wireless charging receiving module. Some mobile phones without built-in receiving module need an external receiving chip, and the use of the receiving chip is also very simple (plug into the mobile phone charging port). The wireless charger needs to be connected to the power supply, but the phone can be placed on the wireless charger for wireless charging of the phone.
Wireless mobile power working principleIt is the use of electromagnetic induction, that is, when the current passes through the coil, a magnetic field is generated, a voltage is formed, and a current is generated after the voltage is charged. You can charge your phone even without a cable. Wireless charging is a device or device with a built-in battery that obtains power through wireless induction. The technology stems from wireless power delivery.
The principle of wireless charging mobile power supply: magnetic energy is converted into electrical energy, according to the principle of induction cooker because wireless charging requires a transmitter and receiver, so wireless charging mobile power supply is installed on the basis of conventional mobile power supplyThe charging mobile phone supports wireless charging and has a wireless charging receiving coil.
Wireless charging technology is also known as inductive charging, non-contact inductive charging, from wireless power transmission technology, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the power device, the device uses the received energy to charge the battery, and at the same time for its own operation.
Protect device interface: Wireless charging avoids frequent insertion and removal of charging cables, reduces the risk of device interface wear, and is conducive to extending device life. Don't underestimate this data interfaceWear and tear Oh, wear and tear will really affect the use of mobile phones. Flexible charging: Although wireless charging treasure is wireless, in fact, it often supports wired charging, and it is very convenient to choose which one. And it can be used with multiple devices.
Millet, Patriot, Featherbo, Scud is better, I am now using Patriot mobile power, good oh, my roommate is using small Mi mobile power, is also used well.
It is on the basis of ordinary mobile power to add a wireless charger, wireless charger refers to the use of electromagnetic wave induction principle for charging equipment. Current mainstreamThere are three Wireless charging standards: Power Matters Alliance (PMA) standard, Qi standard, and Alliance for Wireless Power (A4WP) standard.
