[0033] For further information, see Figure 1-Figure 3, the body 2 is also provided with a control module 6 and a display module 7, the control module 6 is electrically connected to the drive device 21 and the display module 7 at the same time; the display module 7 includes a first indicator light 71 and a second indicator light 72, the first indicator light 71 and the second indicator light 72 are both arranged on the side of the body 2; the control module 6 includes a control chip, so that the control module 6 can send an electrical signal to the display module 7 based on the working speed of the drive device 21, so that one of the first indicator light 71 and the second indicator light 72 is lit and the other is extinguished. Such a setting is convenient for the user to roughly know the working speed of the drive device 21, so as to reasonably select and use the working speed. In order to facilitate the switching of the working speed of the drive device 21 and thus switch the use mode, a switch button 61 is also provided on the body 2, and the switch button 61 is electrically connected to the control module 6. In this embodiment, the drive device 21 has two working speeds of low frequency and high frequency. At low frequency, the number of rotations per minute of the drive motor 211 of the drive device 21 is between 5000-6000. At high frequency, the number of rotations per minute of the driving motor 211 of the driving device 21 is between 8000 and 9000. Before each use, the children's electric toothbrush 100 will be reset to the low-frequency mode, that is, when the switch button 61 is pressed for the first time to start the driving device 21, the driving motor 211 works at a low-frequency speed, and the first indicator light 71 is off, and the second indicator light 72 is on. At this time, if the switch button 61 is pressed again within five seconds, the driving motor 211 will work at a high-frequency speed, and the first indicator light 71 will be on, and the second indicator light 72 will be off. Specifically, a program is also preset in the control chip of the control module 6. When the driving motor 211 runs continuously for two minutes, the control module 6 will send an electrical signal to the driving motor 211, and the driving motor 211 will stop running. In addition, within two minutes of continuous operation of the driving motor 211, the switch button 61 is pressed for two seconds. Under the action of the control module 6, the driving motor 211 will also stop running immediately, and the display module 7 will also be completely extinguished. In addition, the second indicator light 72 is also used as a charging indicator light. When the DC power supply 212 is charged through the charging interface 41, the second indicator light 72 will light up in a continuously flashing manner.

[0034] For further information, see Figure 1-Figure 3, the display module 7 also includes a flashing light group 73, the flashing light group 73 has a plurality of flashing lamp beads 730, and the plurality of flashing lamp beads 730 are arranged at intervals on the side of the body 2 along the length direction of the body 2; the control module 6 can send an electrical signal to the display module 7 based on the working speed of the driving device 21, so that the plurality of flashing lamp beads 730 of the flashing light group 73 flash back and forth in sequence from one end to the other end or flash back and forth in sequence from the two ends to the middle, and then from the middle to the two ends. In this embodiment, the number of the flashing lamp beads 730 is five. When the children's electric toothbrush 100 is used in low-frequency mode, the flashing lamp bead 730 farthest from the brush head 1 flashes first. The remaining flashing lamp beads 730 will first flash and light up in sequence from the bottom to the top of the main body 2. When all of the flashing lamp beads 730 are lit, the flashing lamp bead 730 closest to the brush head 1 remains lit, and the remaining flashing lamp beads 730 will first be all extinguished, and then flash and light up in sequence from the top to the bottom of the main body 2. At this time, after all of the flashing lamp beads 730 are lit again, the flashing lamp bead 730 farthest from the brush head 1 remains lit, and the remaining flashing lamp beads 730 will first be all extinguished, and then flash and light up in sequence from the bottom to the top of the main body 2, and this cycle will be repeated. When the children's electric toothbrush 100 is used in high-frequency mode, the two flashing lamp beads 730 at the two ends flash and light up at the same time, and then the three flashing lamp beads 730 in the middle also flash and light up. When the five flashing lamp beads 730 are all flashing and light up, the two flashing lamp beads 730 at the two ends are first extinguished, and then flash and light up again. When the five flashing lamp beads 730 are flashing and light up again, the three flashing lamp beads 730 in the middle are first extinguished, and then flash and light up again, and so on. This setting increases the fun of use and the fashion of the appearance, which can enhance children's willingness to use.

[0035] The following is a description of the working principle of the children's electric toothbrush 100 provided by the utility model. Before use, first charge the DC power supply 212 through the charging interface 41. After it is fully charged, squeeze toothpaste on the bristles 121. When using, hold the body 2 and press the switch button 61. Since the drive device 21 will default to running at a low-frequency speed when it is started, and the second indicator light 72 is on, the drive device 21 will drive the push rod 13 up and down at a low-frequency speed, thereby pushing the hair implantation head 12 to reciprocate relative to the mounting rod 11. Under the action of the hair implantation head 12, the bristles 121 break down the toothpaste into fine foam to deeply clean the gaps between teeth. At this time, if you need to switch to a high-frequency speed to enhance the tooth cleaning effect, you need to press the switch button 61 again within five seconds of the first startup. After the switch is successful, the first indicator light 71 will light up. If the switch button 61 is not pressed within five seconds, the switch button 61 can be pressed for two seconds to stop the drive device 21, and then the switch button 61 can be used to restart the drive device 21, and the switch button 61 can be pressed again within five seconds to switch to a high-frequency rotation speed. After determining the use mode of the children's electric toothbrush 100, the drive motor 211 will continue to run for two minutes, driving the bristle head 12 to reciprocate for two minutes to clean the teeth. After two minutes, the drive motor 211 automatically stops running under the action of the control module 6, indicating that the teeth cleaning is over. At this time, the bristles 121 can be washed and dried for the next use. In addition, when the children's electric toothbrush 100 works in different use modes, the flashing lamp beads 730 of the flashing lamp group 73 will also flash alternately in different flashing modes.

[0036] Compared with the prior art, the electric toothbrush 100 for children provided by the utility model is configured such that the hair implanting head 12 is rotatably disposed at one end of the mounting rod 11, and a push rod 13 is disposed inside the mounting rod 11 and can be vertically raised and lowered relative to the mounting rod 11 to push the hair implanting head 12 to rotate, and the sound absorbing device 3 is disposed between the hair implanting head 12 and the mounting rod 11, so that when the electric toothbrush 100 for children is in use, the noise generated by the collision of the hair implanting head 12 due to relative rotation is greatly reduced, and at the same time, the sound absorbing device 3 can also absorb part of the vibration generated by the hair implanting head 12, thereby improving the comfort of use. In addition, the electric toothbrush 100 for children provided by the utility model is configured such that the driving device 21 is disposed to drive the push rod 13 to rise and fall, thereby pushing the hair implanting head 12 to rotate, thereby reducing the vibration generated by the brush head 1 and further improving the comfort of use.

[0037] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention.
