It should be noted that the charging port of the electric toothbrush encounters water is no problem, but if it is stained with water, it can not be charged, otherwise it is easy to cause short circuit, the correct step is to throw the water out in time after the charging port is floodedCome on, then dry it. Usually if there is no need for charging, after water, you can put the electric toothbrush in a dry place to dry the water, or use cotton, napkins and other items to dry the water.
Wireless charging, and even remote sensing charging. Its principle is electromagnetic induction, which is usually used in small power situations and does not require electrode contact points. There are induction coils in the small column and electricity, there are induction coils in the electric toothbrush insertion part, and there are plastic insulation outside, there is no electrical contact, and the induction obtains electricity to charge the battery and drive the small motor.
The basic principle of wireless charging, that is, the currentIt is converted into a magnetic field, which is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
The principle of wireless charging is that through near-field induction, the wireless charging device conducts energy to the charging terminal device, and the terminal device converts the received energy into electrical energy, which is stored in the battery of the device. The principle of energy conduction is inductive coupling, which can be guaranteed withoutExposed conductive interface. It can not only eliminate messy transmission lines between devices, but also be safer for electronic devices such as electric toothbrushes that are often in contact with conductive media such as liquids.
As long as it is a toothbrush with IPX7 waterproof performance, it is no problem to wash the whole body even if the interface is left. The biggest advantage of plug-in charging is that it is short in time, which is more human.
1, short circuit or circuit damage. Car mobile phone wireless charger essenceOn is an electronic device that, if it encounters water, may cause a short circuit or damage to the circuit, resulting in failure to work properly. In addition, electronic devices may generate current after encountering water and cause safety hazards, such as electric shock. If you accidentally put a mobile phone wireless charger in water, do not use it, but take it out as soon as possible and power it off, and then dry the device.
2, certainly will not, the principle of wireless charging is electromagnetic induction, wireless power transmission. There's water on the back, there's stuff, there's the shell. At most, it is shielded and cannot be received, but it will definitely not cause damage to either party's equipment. As long as the water doesn't get into the equipment.
3, good sealing performance can effectively protect the internal components from contamination. Note: With IEC 60529 Ed.2:2013 defined IP68 dust and waterproof grade, waterproof testing conditions are (1) no flowing water, water depth of 5 meters; (2) The test time is 30 minutes; (3) The temperature difference between the water temperature and the product is not more than 5K. Please strictly follow the instructions on dustproof and waterproof in the product manual, otherwise the user shall bear the responsibility for the damage caused by the equipment.
4. Liquid is detected when the mobile phone is chargingThe failure to charge may be that the mobile phone charging interface is accidentally flooded, or the air humidity is high, and water vapor slowly accumulates in the interface. The solution is as follows: Put the phone port down, gently pat the phone with your hand to drain the liquid in the phone, and then put the phone in a ventilated, dry place for a day before trying to charge it.
5, please do not frequently shake or shake the mobile phone after water, to avoid water in the mobile phone spread. Please do not use a hair dryer or stove to bake after water, so as to avoid liquid flowing into the inside of the phone and high temperature damage to the phone. Some mobile phones can be turned on normally after simple processing, but handsThe star mobile phone will detect whether the charging port is wet when charging, and if it is wet, it is normal to use wireless charging.
2, reason: This is a protection program of the mobile phone, indicating that the charging port of the mobile phone may be flooded without knowing it, so as not to damage the mobile phone parts due to short circuit.
3, there is a foreign body inside the mobile phone charging port: If there is a foreign body inside the mobile phone charging port, it may also lead to the display of water drop signs. This situation can be used by cleaning the charging port, or replacing the wireless charger. Mobile phone charging cable and charger problems: Sometimes mobile phone charging cable and chargeFailure of electrical appliances can also cause this problem, try to replace the original charger and charging cable, or use another brand of charger and charging cable.
4, mobile phones that support wireless charging are Xiaomi Samsung S10 Plus, iPhone XS Xiaomi 9 Xiaomi 9 uses Snapdragon 855 processor, 39-inch Samsung OLED water drop screen, the screen accounts for 90.7%, Rear 48 megapixel (SONY IMX586 sensor) 16 megapixel (ultra wide Angle) 12 megapixel triple camera (Portrait), 2x optical zoom, 10x digital zoom。< / p >
