Electric toothbrushes are easy to use and can well ensure the standardization of brushing time and brushing movements; they are more ergonomic, have strong cleaning power, cause less damage to teeth and gums, improve brushing efficiency, and save time and effort.

[0035] As the use of electric toothbrushes becomes more and more widespread, users' requirements are also getting higher and higher.

Basically, the chip is pre-burned with programs, and the chip is assembled and assembled into a complete machine for sale. If you want to upgrade the program, you need to disassemble the machine before proceeding, which takes a long time and will cause varying degrees of damage to the electric toothbrush, affecting the reliability of the electric toothbrush.

[0036] Based on this, the embodiment of the present invention provides a device for burning a program through a TYPE-C data cable, which can realize program upgrade without disassembling the machine, thereby improving the upgrade efficiency and being convenient and fast.

[0045] The A4 and A9 pins on the TYPE-C male connector 12 are also connected to the B4 and B9 pins after being short-circuited. Similarly, the A1 and A12 pins on the TYPE-C male connector 12 are also connected to the B1 and B12 pins after being short-circuited.

[0046] The VBUS pins (A9 and B9) on the TYPE-C female socket 20 are connected to the (two) VBUS pins on the TYPE-C female socket lead interface 22; the GND (A12 and B12) pins on the TYPE-C female socket 20 are connected to the (two) GND pins on the TYPE-C female socket lead interface 22.

[0047] The two GND pins on the TYPE-C female socket lead interface 22 are connected to the GND pin on the charging interface 41 ; the two VBUS pins on the TYPE-C female socket lead interface 22 are connected to the VCC pin on the charging interface 41 .

[0048] The device to be programmed 40 includes a charging interface 41 and a chip to be programmed 42. The chip to be programmed 42 uses ATtiny1617, whose 23rd pin is the PA0 / RESET / UPDI pin, and the 23rd pin is connected to the UPDI pin on the charging interface 41 to prepare for program programming.

[0049] This embodiment is connected to the burning device 30 through the USB interface 11, the first data transmission pin and the second data transmission pin on the USB interface 11 are short-circuited, and the first data transmission pin on the USB interface 11 is connected to the first configuration channel pin on the TYPE-C male interface 12; the third data transmission pin, the fourth data transmission pin and the first configuration channel pin on the TYPE-C male interface 12 are short-circuited and connected to the second configuration channel pin; the third configuration channel pin and the fourth configuration channel pin on the TYPE-C female lead interface 22 are short-circuited and connected to the UPDI pin on the charging interface 41, and the UPDI pin on the charging interface 41 is connected to the second UPDI pin on the chip to be burned 42, thereby realizing data transmission between the burning device 30 and the device to be burned 40, and program burning and program upgrade can be realized without disassembling the machine, thereby improving upgrade efficiency and being convenient and quick; at the same time, blind insertion of the TYPE-C interface is realized by short-circuiting, which is convenient for user operation and conducive to improving user experience.

[0050] Optionally, the first data transmission pin is a D-pin on the USB interface 11 , and the first data transmission pin is a D-pin on the USB interface 11 .

[0051] Specifically, since the D+ and D− pins on the USB interface 11 are short-circuited, the first data transmission pin may also be the D+ pin on the USB interface 11 , and then the first data transmission pin is the D+ pin on the USB interface 11 .

[0052] Optionally, the first configuration channel pin includes a CC pin on the TYPE-C male connector 12 .

[0053] Optionally, the third data transmission pin is a D+ pin on the TYPE-C male socket interface 12 , and the fourth data transmission pin is a D− pin on the TYPE-C male socket interface 12 .

[0054] Optionally, the second configuration channel pin is a VCONN pin on the TYPE-C male interface 12 .

[0055] Optionally, the third configuration channel pin is the CC1 pin on the TYPE-C female socket lead interface 22; the fourth configuration channel pin is the CC2 pin on the TYPE-C female socket lead interface.

[0056] Specifically, Figure 2 As shown, the CC pin, D+ pin, and D- pin on the TYPE-C male interface 12 are short-circuited with the D+ and D- pins on the USB interface 11, respectively. After short-circuiting, they are also connected to the VCONN pin on the TYPE-C male interface 12, so that the TYPE-C female interface 21 can transmit data to the CC1 pin and CC2 pin on the TYPE-C female lead interface 22 regardless of whether it is plugged in forward or reverse, thereby realizing blind plugging.

[0057] In order to achieve blind insertion, it is also necessary to short-circuit the CC1 pin and CC2 pin on the TYPE-C female socket lead interface 22.

[0058] Furthermore, in order to allow a larger current to pass, the VCONN pin (B5) on the TYPE-C male connector 12 is short-circuited with the B6 pin and the B7 pin.

[0059] After the data is short-circuited through the D+ pin on the USB interface 11 and the D- pin on the USB interface 11, it is connected to the UPDI pin on the burning device 30 as one path. During data transmission, the data passes through the D+ pin on the USB interface 11 and the D- pin on the USB interface 11 to reach the CC pin on the TYPE-C male socket, the D+ pin on the TYPE-C male socket, and the D- pin on the TYPE-C male socket; the CC pin on the TYPE-C male socket, the D+ pin on the TYPE-C male socket, and the D- pin on the TYPE-C male socket respectively transmit the data to the CC1 pin on the TYPE-C female socket 20 and the CC2 pin on the TYPE-C female socket 20; the CC pin on the TYPE-C female socket 20 1 pin and CC2 pin on the TYPE-C socket 20 then transmit the data to the CC1 pin on the TYPE-C socket lead interface 22 and the CC2 pin on the TYPE-C socket lead interface 22, and the CC1 pin on the TYPE-C socket lead interface 22 and the CC2 pin on the TYPE-C socket lead interface 22 are short-circuited to transmit the data to the UPDI pin on the charging interface 41, and the UPDI pin on the charging interface 41 is connected to the PA0 / RESET / UPDI pin on the device to be burned 40, thereby realizing program burning.

[0060] Furthermore, we can also use Figure 3 Data is transmitted in the manner shown, but blind insertion cannot be achieved in this manner.

[0061] Specifically, the D+ pin on the USB interface 11 or one of the D- pins on the USB interface 11 is connected to the UPDI pin on the burning device 30 and the CC pin on the TYPE-C male connector 12 respectively.

[0062] This connection method can connect the UPDI pin on the burning device 30 to the D-pin on the USB interface 11, and the D-pin on the USB interface 11 to the CC pin on the TYPE-C male interface 12. After the TYPE-C male interface 12 is connected to the TYPE-C female interface 21, the CC pin on the TYPE-C male interface 12 is connected to the CC1 pin on the TYPE-C female interface 21, and the CC1 pin on the TYPE-C female interface 21 is connected to the CC1 pin on the TYPE-C female lead interface 22.

[0065] Optionally, the programming device 30 and the device to be programmed 40 are both connected to the device 100 for programming via a TYPE-C data line by using a UPDI interface.

[0066] Optionally, the device to be burned 40 is an electric toothbrush, which includes an electric toothbrush charging interface and an electric toothbrush chip to be burned, the electric toothbrush charging interface is provided with a first electric toothbrush UPDI pin, and the electric toothbrush chip to be burned is provided with a second electric toothbrush UPDI pin, and the first electric toothbrush UPDI pin is connected to the second electric toothbrush UPDI pin.
