[0030] The technical solutions of the present invention will be further specifically described below through embodiments in conjunction with the drawings.

[0031] As Figures 1 to 6 shown, a magnetic levitation sonic electric toothbrush includes a toothbrush body 3, a charging base 4 and a charging cable 5. A charging port 6 is provided at the lower end of the toothbrush body 3. The charging base 4 includes a housing 41, a charging head 42 and a backup battery 43. The charging head 42 is installed on the upper side of the housing 41. The backup battery 43 is electrically connected to the charging head 42. The charging head 42 can be inserted into the charging port 6 of the toothbrush body 3 to charge the main battery (not shown in the figure) in the toothbrush body 3 or supply power to the magnetic levitation motor (not shown in the figure) of the toothbrush body 3. A connection port 44 connected to the charging cable 5 is provided on the housing 41. The charging cable 5 is used to charge the backup battery 43.

[0032] Through the above settings, during normal use, the toothbrush body 3 is placed on the charging base 4, and the charging base 4 charges the toothbrush body 3. When the main battery in the toothbrush body 3 is low on power, the charging head 42 of the charging base 4 is inserted into the charging port 6 of the toothbrush body 3, and the backup battery 43 in the charging base 4 can temporarily supply power to the magnetic levitation motor in the toothbrush body 3, facilitating the user to continue using the toothbrush body 3 for brushing teeth in an emergency.

[0033] The toothbrush body 3 of the present application can refer to existing magnetic levitation sonic electric toothbrushes, which include a handle, a main battery, a toothbrush head, and a magnetic levitation motor. The charging port 6 is located at the lower end of the handle. The main battery and the magnetic levitation motor are installed inside the handle. The main battery powers the magnetic levitation motor. The toothbrush head is installed at the upper end of the handle and is driven by the magnetic levitation motor. The charging port 6 and the charging head 42 can adopt a Type-C interface or other forms of interfaces. The end of the charging cable 5 is a USB connector, which is convenient for connecting to a USB interface to draw power. After the charging cable 5 is connected to an external power source, the charging cable 5 charges the backup battery 43. During normal use, the toothbrush body 3 of the present application is used in the same way as existing magnetic levitation electric toothbrushes. When the power of the main battery is insufficient, the toothbrush body 3 is inserted downward onto the charging head 42, and the backup battery 43 charges the main battery through the charging head 42 and the charging port 6. When the user needs to brush their teeth when the main battery has insufficient power, the user can pick up the toothbrush body 3 together with the charging base 4 to brush their teeth. At this time, the backup battery 43 serves as a backup power source to supply power to the magnetic levitation motor, which does not affect the user's brushing. After brushing, the charging base 4 is placed back on the table, and the backup battery 43 in the charging base 4 continues to charge the main battery.

[0034] As an implementation, the charging cable 5 is detachably connected to the connection port 44.

[0035] After unplugging the charging cable 5 from the connection port 44, when the user brushes their teeth with the toothbrush body 3 connected to the charging base 4, it is lighter in weight and more labor-saving. Among them, the connection port 44 can adopt an existing Type-C interface.

[0036] As an implementation, the charging base 4 further includes a locking mechanism 45 that can lock the lower end of the toothbrush body 3 to the charging base 4.

[0037] Through the above settings, the connection reliability between the charging base 4 and the toothbrush body 3 is improved, preventing the charging base 4 from falling off during the brushing process.

[0038] After the lower end of the toothbrush body 3 of the present application is inserted into the upper side of the charging base 4, the locking mechanism 45 locks the toothbrush body 3 and the charging base 4 together. When the toothbrush body 3 is inserted into the upper side of the charging base 4 for charging, the toothbrush body 3 and the charging base 4 will not separate, thus avoiding the occurrence of charging interruption. In addition, when the user brushes their teeth with the toothbrush body 3 connected to the charging base 4, the charging base 4 is not easily detached from the bottom of the toothbrush body 3 during the movement of the toothbrush body 3, preventing the power supply of the connection base from being interrupted.

[0039] As an implementation, a plug pin 7 is fixedly connected to the lower end of the toothbrush body 3. A lock hole 8 is provided on the plug pin 7. An insertion slot 9 adapted to the plug pin 7 is provided on the upper side of the housing 41. The plug pin 7 is inserted into the insertion slot 9. The locking mechanism 45 includes a lock pin 451 and a driving mechanism 452. The lock pin 451 is slidably connected in the housing 41 and passes through the lock hole 8. The driving mechanism 452 can drive the lock pin 451 to move axially. The main battery of the toothbrush body 3 supplies power to the driving mechanism 452.

[0040] Through the above settings, the charging base 4 locks the toothbrush body 3 on the upper side of the housing 41 of the charging base 4 through the lock pin 451 and the plug pin 7.

[0041] The driving mechanism 452 of the present application can drive the lock pin 451 to move axially. When the lock pin 451 retracts, the insertion end of the lock pin 451 leaves from below the insertion slot 9. At this time, the plug pin 7 can be inserted downward into the insertion slot 9 or pulled out from the insertion slot 9. Among them, the plug pin 7 being inserted downward into the insertion slot 9 corresponds to the toothbrush body 3 being placed on the charging base 4, and the plug pin 7 being pulled out from the insertion slot 9 corresponds to removing the toothbrush body 3 from the charging base 4; when it is necessary to lock the toothbrush body 3 and the charging base 4, the plug pin 7 is inserted downward into the insertion slot 9, and the driving mechanism 452 drives the lock pin 451 to axially insert into the lock hole 8 to prevent the plug pin 7 from being pulled out from the insertion slot 9, that is, to prevent the toothbrush body 3 from being disconnected from the charging base 4.

[0042] As an implementation, the locking mechanism 45 further includes a guide rod 453 and a sleeve 454. The sleeve 454 is fixedly connected in the housing 41. The guide rod 453 passes through the sleeve 454 and is slidably connected to the sleeve 454. The guide rod 453 is coaxial or parallel to the lock pin 451.

[0043] Through the above settings, the lock pin 451 is slidably connected in the housing 41 through the guide rod 453 and the sleeve 454.

[0044] As an implementation, the locking mechanism 45 further includes a spring 455. The spring 455 is sleeved on the guide rod 453. One end of the spring 455 is connected to the sleeve 454, and the other end of the spring 455 is connected to the lock pin 451. An inclined surface 456 is provided at the insertion end of the lock pin 451. The plug pin 7 presses against the inclined surface 456 downward, and the lock pin 451 axially moves away from the plug pin 7 and compresses the spring 455.

[0045] Through the above settings, when the plug pin 7 is inserted into the insertion slot 9, under the action of the spring 455 and the inclined surface 456, the lock pin 451 automatically locks the plug pin 7.

[0046] When the spring 455 of the present application is in a free state, the elastic force is zero, and the lock pin 451 is inserted into the lock hole 8. At this time, the latch 7 cannot be pulled out from the slot 9, and the toothbrush body 3 and the charging base 4 are locked together; after the driving mechanism 452 drives the lock pin 451 to retract, the spring 455 is compressed, and the lock pin 451 is pulled out from the lock hole 8. At this time, the toothbrush body 3 can be removed from the charging base 4; after the driving mechanism 452 loses power, the spring 455 rebounds freely and returns to a free state; when the toothbrush body 3 is placed on the charging base 4 again, the latch 7 is inserted downward into the slot 9, and after the lower end of the latch 7 presses down the inclined surface 456, under the action of the inclined surface 456, the lock pin 451 retracts and abuts against the side of the latch 7, and the spring 455 is compressed. When the lock hole 8 on the latch 7 moves downward to the lock pin 451, the spring 455 automatically rebounds, and the lock pin 451 automatically inserts into the lock hole 8 to lock the latch 7.

[0047] As an implementation method, the driving mechanism 452 includes a rack 4521, a gear 4522 and a motor 4523. The rack 4521 is coaxial or parallel to the locking pin 451, and the rack 4521 is fixedly connected to the locking pin 451. The motor 4523 is fixedly installed in the housing 41 and is transmission connected to the gear 4522, and the gear 4522 is meshed with the rack 4521.

[0048] Through the above arrangement, the motor 4523 drives the locking pin 451 to move via the gear 4522 and the rack 4521 .

[0049] As an implementation method, two slots 9, two latches 7 and two lock pins 451 are provided and are arranged on opposite sides of the charging head 42. The two lock pins 451 are fixedly connected by a connecting rod 457. The rack 4521 is fixedly connected to the middle part of the connecting rod 457 and extends back to the charging head 42.

[0050] Through the above arrangement, when the locking mechanism 45 locks the toothbrush body 3 on the charging base 4, the toothbrush body 3 and the charging base 4 are less likely to be disengaged.

[0051] As an implementation manner, the driving mechanism 452 further includes a button 4524 for controlling the operation of the motor 4523 , and the button 4524 is disposed on the upper side of the housing 41 .

[0052] Through the above settings, the movement of motor 4523 is controlled by button 4524.

[0053] Specifically, each time the button 4524 is pressed, the motor 4523 drives the locking pin 451 to retract by 1 cm so that the user can remove the toothbrush body 3 from the charging base 4. After the locking pin 451 retracts and holds for 5 seconds, the motor 4523 loses power and the locking pin 451 automatically retracts to save power. When the toothbrush body 3 needs to be placed back on the charging base 4, the button 4524 needs to be pressed again. After the locking pin 451 retracts, the toothbrush body 3 is placed on the charging base 4. After the motor 4523 loses power, the locking pin 451 automatically inserts into the lock hole 8.

[0054] As an implementation, the charging base 4 further includes a rubber protrusion 10 provided on the lower side of the housing 41.

[0055] Through the above settings, the anti-slip performance of the charging base 4 is improved.

[0056] It should be understood that for those of ordinary skill in the art, improvements or changes can be made according to the above description, and all such improvements and changes should fall within the protection scope of the appended claims of the present utility model.
