DETAILED DESCRIPTION
[0021] With reference to the drawings of some embodiments of the present application, the technical solutions in some embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.
[0022] The technical solutions of the embodiments of the present application will be described in detail below with reference to the drawings.
[0023] As shown in Figure 1 The rotating toothbrush head 2 is usually used on an electric toothbrush, which includes a shell 21, a connecting rod (not shown in the figure) and a brush disc 23 provided with bristles 24, the brush disc 23 is rotatably installed on the shell 21, the connecting rod is located in the shell and linked with the brush disc 23, and a motor of the electric toothbrush drives the connecting rod to reciprocating rotation to drive the brush disc 23 to reciprocating rotation.
[0024] As shown in Figures 2 to 5 The dust cover 1 of the rotating toothbrush head 2 in the embodiment is a shell structure with an open lower end, the dust cover 1 is provided with a cavity 101 for accommodating the rotating toothbrush head 2, the rotating toothbrush head 2 is inserted into the cavity 101 through the open lower end, the cavity 101 is internally provided with first rib plates 11 on two opposite first side walls 102 and second side walls 103, respectively, the first rib plates 11 are provided with first grooves 111 formed by inward recess, and the first grooves 111 of the two first rib plates 11 are used for clamping and limiting the shell 21 of the rotating toothbrush head 2; the cavity 101 is provided with a second rib plate 12 on a top wall 104, and the second rib plate 12 is used for abutting against the shell 21 of the rotating toothbrush head 2.
[0025] It should be noted that, since the brush disc 23 of the rotating toothbrush head 2 is rotatably movable relative to the shell 21, the diameter of the brush disc 23 is larger than the size of the shell 21, and the brush disc 23 protrudes out of the shell 21, so the dust cover 1 cannot be fixed on the brush disc 23, but can only be fixed and clamped on the shell 21, the first rib plates 11 are formed on the first side walls 102 and the second side walls 103 of the cavity 101, the first grooves 111 on the first rib plates 11 are used to clamp and limit the shell 21 of the rotating toothbrush head 2, so that the dust cover 1 is fixed on the rotating toothbrush head 2 to prevent the dust cover 1 from falling off; and the abutting of the second rib plate 12 is used to limit the shell on the top wall 104.
[0026] Further specifically, when the dust cover 1 is installed on the rotating toothbrush head 2, the first side walls 102 and the second side walls 103 are located on both sides of the rotation axis of the brush disc 23, and the length direction of the first rib plates 11 is perpendicular to the rotation axis, and the two first rib plates 11 are symmetrically arranged.
[0027] In the embodiment, the part of the shell 21 contacting the dust cover 1 is similar to a cylinder, so the first groove 111 is an arc-shaped groove, so that the first groove 111 cooperates with the shell 21 of the rotating toothbrush head 2. Similarly, the second groove 121 on the second rib plate 12 is arc-shaped, so that the second groove 121 cooperates with the surface of the shell 21 of the rotating toothbrush head 2.
[0028] In the embodiment, the third rib plate 13 is arranged on the top wall 104 of the cavity 101, and the third rib plate 13 protrudes downward to abut against the bristles 24 of the rotating toothbrush head 2, so as to prevent the bristles 24 from contacting the top wall 104.
