[0034] A USB socket 302 and a guide hole 303 are provided on the lower cover 3 of the body. A female socket cover 304 is provided on one side of the USB socket 302 . A USB female socket 310 is provided inside the female socket cover 304 . An external TYPE-C charging cable is inserted from the USB socket 302 into the USB female socket 310 .

[0035] A guide cylinder 305 is provided below the female base cover 304, and the guide cylinder 305 is connected to the guide hole 303. A guide rod 102 is provided on the bottom cover 1, and a stopper 103 is provided on the guide rod 102. The stopper 103 is located in the fuselage body 5, and the guide rod 102 is located in the guide hole 303. The size of the stopper 103 is larger than the size of the guide hole 303. When the bottom cover 1 and the button cover 2 are pulled outward, the guide rod 102 is pulled out along the guide hole until the stopper 103 abuts against the guide hole 303.

[0036] A PVC sealing film 104 is provided at one end of the guide rod 102 to mitigate the impact force of the guide rod 102 on the motor bracket 6 and the battery 603 during the pulling process.

[0037] A first through hole 306 is provided on the lower cover 3 of the fuselage, an indicator light is provided in the first through hole 306 , and a waterproof breathable membrane 307 is provided on one side of the first through hole 306 .

[0038] First buckles 308 are respectively provided on both sides of the lower body cover 3 , and second buckles 309 are provided on both sides of one end of the motor bracket 6 . The first buckle 308 is connected to the second buckle 309 , so that the lower body cover 3 is connected to the motor bracket 6 .

[0039] The USB socket cover 304 is located between the second buckles 309 and connected to the second buckles 309 , so that the USB socket cover 304 is fixed.

[0040] Charging the toothbrush. First, use your fingernail to gently push open the button cover 2, and then pull it outward for a certain distance until you feel a blockage; connect the TYPE-C charging cable and insert it into the USB port 302 to charge; when charging is complete, the indicator light turns green; then you can unplug the TYPE-C charging cable, cover the button cover 2, and the electric toothbrush can be used normally.

[0041] A fuselage body 5 is sleeved on the fuselage lower cover 3 , and an O-ring 4 is arranged between the fuselage body 5 and the fuselage lower cover 3 to seal the fuselage body 5 and the fuselage lower cover 3 .

[0042] like Figure 5 and Figure 7 As shown, guide blocks 601 are provided on both sides of the motor bracket 6, and guide rails 501 are provided on the fuselage body 5. During installation and disassembly, the guide blocks 601 move along the guide rails 501, so that the motor bracket 6 can be accurately installed in the fuselage body 5 to prevent the button 7 from being inaccurately docked with the fuselage PCBA602, thereby affecting the sensitivity of the button 7.

[0043] A third inner cavity is provided on the motor bracket 6, and a battery 603 is provided in the third inner cavity. Connecting pieces 604 are provided at both ends of the battery 603. The connecting pieces 604 penetrate the motor bracket 6 and are connected to the body PCBA 602 provided above the motor bracket 6. The body PCBA 602 is fixed to the motor bracket 6 by screws.

[0044] The inner wall of the third inner cavity is provided with an anti-slip design to prevent the battery 603 from sliding.

[0045] A first rib 605 is provided at one end of the motor bracket 6, and a second through hole 606 is provided on the first rib 605. A motor bracket anti-vibration pad 8 is provided on one side of the motor bracket 6 at the end, and the shape of the motor bracket anti-vibration pad 8 matches the shape of the first rib 605 and the second through hole 606. A toothbrush inner shaft 901 is provided on one side of the motor bracket anti-vibration pad 8, and one end of the toothbrush inner shaft 901 has the same shape as the motor bracket anti-vibration pad 8, so the motor bracket 6, the motor bracket anti-vibration pad 8 and one end of the toothbrush inner shaft 901 form a nested structure. The side of the motor bracket anti-vibration pad 8 that contacts the toothbrush inner shaft 901 is designed to be uneven to increase friction and prevent relative sliding during use. A toothbrush inner shaft waterproof ring 902 is provided at one end of the toothbrush inner shaft 901, and the toothbrush inner shaft waterproof ring 902 contacts the slope provided on the inner side of one end of the body 5, and is used to connect the toothbrush head 9 and the body 5. The contact surface between the toothbrush inner shaft waterproof ring 902 and the body 5 is unevenly designed so that the toothbrush inner shaft waterproof ring 902 will not slide relative to the body 5.

[0046] like Figure 2 and Figure 3As shown, the toothbrush head 9 is provided with a thin rib 903, the thin rib 903 is provided with a convex clamp 904, the toothbrush inner shaft 901 is provided with a concave clamp 908, and the concave clamp 908 is connected to the convex clamp 904, so that the toothbrush head 9 and the toothbrush inner shaft 901 are connected more tightly.

[0047] A tight fitting bone 905 is provided on the inner shaft 901 of the toothbrush, and the tight fitting bone 905 is in close contact with the inner wall of the toothbrush head 9 .

[0048] Due to the vibration of the hollow cup motor 906 during use, the inner shaft 901 of the toothbrush may move, so the design of the above structure doubles the stability of the inner shaft 901 of the toothbrush.

[0049] A toothbrush inner shaft waterproof cap 907 is provided at one end of the toothbrush inner shaft 901 , and the toothbrush inner shaft waterproof cap 907 is interference fit with the toothbrush head 9 .

[0050] A coreless motor 906 is disposed in the inner shaft 901 of the toothbrush. The connecting line of the coreless motor 906 is connected to the PCBA 602 of the body to provide power to the coreless motor 906 and also to control the vibration speed of the coreless motor 906 .

[0051] The inner shaft 901 of the toothbrush is also provided with an anti-skid design to prevent the hollow cup motor 906 from sliding. This sliding design can be anti-skid bumps, anti-skid pads, etc.

[0052] The toothbrush head 9 is inserted. When the toothbrush head 9 is inserted, the convex card 904 structure has a double-sided guiding inclined surface. Under the action of pressure, the toothbrush head 9 is partially deformed, so that it enters the concave card 908 of the detail structure of the toothbrush inner shaft 901; after being inserted into place, the tight fitting bone 905 of the toothbrush inner shaft 901 contacts the inner wall of the toothbrush head 9 and is firmly fixed in this position without deflection; in addition, several fine ribs 903 of the toothbrush head 9 also contact the toothbrush inner shaft 901 to prevent the toothbrush head 9 from deflecting and moving on the toothbrush inner shaft 901, and firmly fix it in this position to prevent it from loosening during work, thereby bringing a good experience to the user.

[0053] The toothbrush head 9 is pulled out. The toothbrush head 9 is pulled out from the toothbrush inner shaft 901. At this time, the toothbrush head 9 can be pulled out by holding the toothbrush head 9 tightly with the hand and pulling it outward so that the fine ribs 903 of the toothbrush head 9 are separated from the concave clamps 908 of the toothbrush inner shaft 901. In this process, the toothbrush head 9 will be partially deformed, which brings a good experience to the user.

[0054] Therefore, the utility model adopts the above-mentioned electric toothbrush head and the electric toothbrush that prevents the toothbrush head from loosening, and the charging is convenient and fast, saving time and effort. Without any tools, it can be charged by plugging into the TYPE-C interface; it can be charged in spare time, and when it is full, it will automatically prompt that it is full, saving time and effort; it is simple to operate, and the electric toothbrush is very convenient to charge, and only needs manual operation, without the need for any external force tools. The operation is convenient and simple.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
