Of course, in the case where the display member 950 is disposed at the middle of the light-equalizing member 50, the light effect displayed by the first light-guiding portion 410 is more uniform, and in the case where the display member 950 is disposed at one end of the light-equalizing member 50, the light brightness displayed by the first light-guiding portion 410 has a gradual effect.

Further, the housing 20 further includes a light-shielding member 60 connected to the casing 30, where the light-shielding member 60 includes at least two light-shielding portions 610, and one light-shielding portion 610 separates a combination of a first light-guiding portion 410, a light-homogenizing member 50 and a display member 950 from a combination of another adjacent first light-guiding portion 410, another adjacent light-homogenizing member 50 and another adjacent display member 950. The light-shielding portion 610 in this embodiment is in a strip shape, the length of the light-shielding portion is equal to that of one light-shielding member 50 or the first light-guiding portion 410, the light-shielding member 60 further includes a connection ring 620 connected to the light-shielding portions 610, the first through groove 301 is defined between two adjacent light-shielding portions 610 and between the light-shielding portion 610 and the connection ring 620, wherein the housing 30 is provided with a window 302 (see fig. 6 and 7) corresponding to the light-shielding member 60, the whole structure of the light-shielding member 60 formed by the connection ring 620 and the light-shielding portion 610 covers the window 302, and the light-shielding member and the housing 30 can be connected by means of fastening, gluing or integrally forming. It will be appreciated that the light barrier 60 of the present utility model may also be of unitary construction with the housing 30 (as shown in fig. 8).

The housing 20 further includes a light-transmitting member 70, and a mounting groove is formed in a region of the case 30 where the light-blocking member 60 is mounted, and the light-transmitting member 70 covers and is embedded in the mounting groove. The light-transmitting member 70 of the present embodiment has an arc structure, and the light-transmitting member 70 and the housing 30 may be fixedly connected by fastening, gluing or integrally molding. By adopting the form that the whole mode display area 201 is covered by the whole light-transmitting member 70, on one hand, the light-transmitting member 70 can effectively protect the plurality of first light guide portions 410, on the other hand, the light-transmitting member 70 can enable the whole outer surface of the whole shell 20 to be smooth, and in the process that the light of the first light guide portions 410 is transmitted outwards through the light-transmitting member 70, the light-transmitting member 70 can amplify the display area of the first light guide portions 410 to a certain extent, so that the observation is more convenient.

Further, referring to fig. 7 again, the housing 30 further has a protrusion 630 protruding from a bottom wall of the mounting groove, and the protrusion 630 is disposed between the two first through grooves 301 and extends along a length direction of the first through grooves 301. The structure of the ridge portion 630 and the light blocking member 60 of the present embodiment may be integrally formed, and the ridge portion 630 is formed on the outer side surface of the light blocking portion 610 described above. The bulge 630 abuts against the inner surface of the light-transmitting member 70, and by the arrangement, the bulge 630 achieves the supporting effect on the light-transmitting member 70, so that the light-transmitting member 70 is not easy to deform in the collision and knocking process, and on the other hand, light channeling between adjacent first sub-display areas 202 is further avoided, so that mode display is clearer and easy to distinguish.

In the above, the electric toothbrush 1 of the present utility model has been specifically described in terms of the structural form of the mode display area 201, which has the advantage of easily observing the mode state during use. On the basis, for the convenience of use and observation, the utility model can also be that the included angle between the direction of the brush hair 111 and the axial direction of the key 21 is 30-60 degrees.
