An electrically connected receiving coil 21 and a charging substrate 22 (PCB board) are installed in the end cover 2. A lower conductive spring 23 corresponding to the lower end of the rechargeable battery 12 and a conductive contact 221 corresponding to the elastic joint 13 are provided on the charging substrate 22. The lower conductive spring 23 is electrically connected to the charging substrate 22, and the conductive contact 221 can contact the elastic joint 13 to achieve electrical connection.

[0038] See also Figure 3 and Fig.10 A main control board 14 is installed in the toothbrush body 1, and the main control board 14 is installed on the outer wall of the battery compartment 11. An upper conductive spring 15 is installed inside the end of the battery compartment 11 away from the insertion port 111, and the upper conductive spring 15 is electrically connected to the main control board 14, and the elastic joint 13 is electrically connected to the main control board 14.

[0039] When in use, the rechargeable battery 12 is placed in the battery compartment 11, and the upper end of the rechargeable battery 12 abuts against the upper conductive spring 15; when the end cover 2 is screwed in, the lower conductive spring 23 abuts against the lower end of the rechargeable battery 12, and the conductive contact 221 abuts against the elastic joint 13.

[0040] This structure adopts a detachable end cover, and the rechargeable battery is placed between the upper conductive spring and the lower conductive spring. When the battery life is about to end, the lower end cover can be removed and replaced with a new rechargeable battery, which effectively extends the service life of the electric toothbrush. It is practical and easy to use. Moreover, the battery is detachable, which is more conducive to recycling and environmental protection. Two elastic joints are used as wires to connect with the charging substrate. When disassembling, the elastic force of the elastic joint can make the end cover automatically separate from the body, and the end cover and the body can be completely separated and not connected, so the battery can be smoothly removed, and disassembly and assembly are convenient.

[0041] In some embodiments, Figure 5 and Figure 6As shown, the end cap 2 is detachably connected to the toothbrush body 1 by means of rotational engagement, a plurality of rotational clamps 201 are provided at equal intervals in an annular manner on the outer wall of the end cap 2, and a rotational clamping groove 101 that can be engaged with the rotational clamp 201 is provided on the inner wall of the toothbrush body 1. In this structure, the end cap 2 is detachably connected to the toothbrush body 1 by means of rotational engagement, and assembly and disassembly are very convenient.
