In the present embodiment, as shown in fig. 2 and 3, a battery 4 is further disposed in the handle 10, and the battery 4 can supply power to the driving device 2, so that the driving device 2 can drive the brush head 20 to swing. In the present embodiment, the battery 4 is also used for supplying power to the disinfection lamp 3, the partition 16 is further provided with a wire through hole 162, and the conductive wire 5 passes through the partition 16 from the wire through hole 162 to electrically connect the disinfection lamps 3 together. At this time, in order to prevent water, a sealant 19 is further provided in the wire through hole 162, so that a gap between the conductive wire 5 and the partition 16 is filled with the sealant 19.

In this embodiment, the cover plate 14 and the partition plate 16 divide the mounting cavity 131 of the housing 13 into two relatively closed chambers, so that the disinfection lamp 3 can be mounted in the first chamber 136 from the first opening 134 and the driving device 2, the battery 4 and the like can be mounted in the second chamber 137 from the second opening 135 during production. It is understood that in some embodiments, the housing 1 may not have the partition 16, that is, the installation cavity 131 is not divided, and in this case, the disinfection lamp 3, the driving device 2, and the like may be installed in the installation cavity 131 from the first opening 134 or may be installed in the installation cavity 131 from the second opening 135. In addition, the cover plate 14 may be integrally formed with the housing 13 during production, in which case the bottom cover 15 is disposed separately from the housing 13, and the housing 13 and the rear cover are assembled together after the sterilization lamp 3 and the driving device 2 are assembled. Of course, the rear cover may be integrally formed with the housing 13 during production, and the cover plate 14 may be separately provided from the housing 13 and then assembled with the housing 13 by means of bonding or the like.

In the present embodiment, the on and off of the disinfection lamp can be controlled by the control device disposed in the housing 1, for example, after the brushing (i.e. after the driving device 2 stops working), the disinfection lamp is controlled to be on for a period of time, and then the disinfection lamp is controlled to be off. It will be appreciated that the control means may also be used to control the start and stop operation of the drive means.

As shown in fig. 5, in the present embodiment, the brush head 20 includes a body 6 and a brush head plug 7, wherein one end of the body 6 is provided with bristles 61 for brushing teeth, the other end of the body 6 is provided with a mounting hole 62, the brush head plug 7 is embedded in the mounting hole 62, and the brush head plug 7 has a connection hole 71. When the toothbrush is assembled, the output shaft of the handle 10 extends into the connecting hole 71, and the brush head 20 is connected with the handle 10 through the matching of the output shaft 22 and the connecting hole 71. In this embodiment, the brush head plug 7 is a transparent plug so that ultraviolet light emitted from the sterilizing lamp 3 can pass through the brush head plug 7, so that the inside of the connecting hole 71 can be sterilized and disinfected by the sterilizing lamp 3. In addition, in this embodiment, the material of the brush head plug 7 may be the same as that of the cover plate 14, so that the types of stock can be reduced during production, and the production cost can be reduced to a certain extent.
