Today, Bluetooth technology has gradually penetrated into every corner of our daily life.However, the origin of "Bluetooth" is indeed legendary. It originated from the legendary King Harald V who united Denmark and Norway. His gums were blue because he often ate blueberries, so he was called "Bluetooth", which was translated as "Bluetooth" in English.The name chosen by the founders of Bluetooth technology is precisely the hope that different devices can achieve seamless connection and unified cooperation as Harald V unified northern Europe.
Today, Bluetooth technology has realized this vision, which not only allows devices to easily interconnect data transmission, but also shows its extensive application potential in the field of small household appliances.Recently, when sorting out the past disassembly cases, the charging head network found three charging devices with built-in bluetooth chips. These devices not only have the functions of traditional electric toothbrushes, but also achieve a number of innovative functions such as function control and status synchronization through bluetooth technology, bringing users a new experience.Next, let's take a look at these cases of electric toothbrushes with built-in Bluetooth chips.
Electric toothbrush with built-in Bluetooth chip
Some parameters of the three Bluetooth chips are shown in the figure.
Fengjia Technology PHY6222
Fengjia Technology PHY6222 is an ultra low power SOC that supports Bluetooth BLE5.2 and IEEE 802.15.4 communication protocols. The chip is integrated with multi-mode RF transceiver and equipped with 32-bit ARM Coretx-M0 processor.The maximum transmitting power of the chip transmitter reaches 10dBm;Receiver sensitivity reaches - 99dBm at BLE 1Mbps, link RF budget109dB@1Mbps;IEEE 802.15.4 receiving sensitivity at 250Kbps - 103dBm;At 0dBm, the transmitting and receiving power consumption is 4.6/4MA (TX/RX), and QFN-32 packaging is provided.

Application case
The future adaptive acoustic electric toothbrush planck O1
Planck O1 electric toothbrush is a new product of Evowera in the future. It is available in black and white styles, including a toothbrush handle and two brush heads.The bright surface design of the handle body is equipped with switches, function keys and intelligent display screen, which not only makes it smooth to hold and feel good, but also can switch the brushing mode, timely remind of missing brushing, and connect the evowera APP to set more intimate functions.
The charging head network has learned that Bluetooth technology also plays an important role in the field of smart home.Imagine that when you walk into your home, the smart door lock automatically recognizes your mobile phone through Bluetooth technology to achieve a convenient experience of "unlocking when you are near".Smart lighting systems, air conditioners, curtains and other devices in the home can also be seamlessly connected with your mobile phone or other smart devices through Bluetooth to achieve one button control, making your home devices more intelligent.
When it comes to electric toothbrushes, Bluetooth technology has also brought revolutionary changes.The traditional electric toothbrush can only provide basic cleaning functions. With the addition of Bluetooth technology, the electric toothbrush can record the user's brushing habits, oral health status and other information, and display and analyze them through mobile phone APP. It can also provide personalized brushing suggestions according to the user's oral conditions, which helps the user develop good oral care habits.It is believed that with the continuous progress of technology and the emergence of innovative applications, Bluetooth technology will continue to bring more convenience and surprises to our lives.
