The other structures of the bendable toothbrush head 10 of the present embodiment are the same as those of the bendable toothbrush head 10 of the first embodiment, and will not be described in detail.

Example three:

referring to fig. 4, fig. 4 is a schematic structural view, partially in section, of the flexible toothbrush head of this embodiment. The bendable toothbrush head 10 of the present embodiment differs from the bendable toothbrush head 10 of the first embodiment in that:

in this embodiment, the handle 12 includes five connecting sections 121, the five connecting sections 121 include two soft sections 1211 and three hard rod sections 1212, and the two soft sections 1211 and the three hard rod sections 1212 are alternately arranged, i.e., two connecting sections 121 at two ends are hard rod sections 1212, and one connecting section 121 in the middle is hard rod section 1212. This configuration facilitates connection to the head 11 using one shaft segment 1212 and to the handle 21 via another shaft segment 1212. And also can play a certain supporting role through the middle hard rod segment 1212. While the two spaced-apart flexible segments 1211 may facilitate bending of handle 12. In other embodiments, two connecting segments 121 at two ends and the middle connecting segment 121 can be set as the soft segment 1211, and the other two connecting segments 121 can be set as the hard rod segment 1212.

In some embodiments, the number of the connecting segments 121 can be four, six, etc., and the soft segments 1211 and the hard rod segments 1212 are alternately arranged.

Example four:

referring to fig. 5 and 6, the bendable toothbrush head 10 of the present embodiment differs from the bendable toothbrush head 10 of the first embodiment in that:

in this embodiment, the brush head 11 includes a brush holder 111, a floating brush 112, a ball hinge structure 114 and a vibration guide structure 113, and the brush holder 12 is connected to the brush holder 111 to support the brush holder 111 via the brush holder 12. The brush holder 111 is provided with a first receiving cavity 1111 therein, the ball hinge structure 114 is installed in the first receiving cavity 1111, and the floating brush 112 is installed on the ball hinge structure 114, and the floating brush 112 is supported by the ball hinge structure 114, so that the floating brush 112 can swing on the brush holder 111 in any direction. The floating brush 112 includes first bristles 1122 and a floating brush holder 1121, and the first bristles 1122 are mounted on the floating brush holder 1121 to support the first bristles 1122 through the floating brush holder 1121. The floating brush seat 1121 is disposed in the first receiving cavity 1111, and the floating brush seat 1121 is connected to the ball hinge structure 114 so as to support the floating brush seat 1121 in the first receiving cavity 1111 through the ball hinge structure 114, so that a gap is formed between the side wall of the first receiving cavity 1111 and the floating brush seat 1121, so that the floating brush seat 1121 can swing in the first receiving cavity 1111, and thus the first bristles 1122 can better fit the surface of teeth during brushing teeth. In addition, the gap between the sidewall of the first receiving cavity 1111 and the floating brush holder 1121 can also limit the swing angle of the floating brush holder 1121. The vibration guide structure 113 is used for guiding vibration, and the vibration guide structure 113 is also used for limiting the rotation of the floating brush holder 1121. Therefore, when the main body 20 of the electric toothbrush 100 drives the brush handle 12 to oscillate, the brush support 111 is driven to oscillate and vibrate, and further the vibration is transmitted to the floating brush 112 through the vibration guide structure 113. Thereby driving the floating brush seat 1121 and the first bristles 1122 to oscillate and vibrate, so as to realize vibration conduction, thereby cleaning teeth and improving the cleaning effect.
