[0063] Example 1

[0064] Figure 1-Figure 3 FIG. 1 shows a structural diagram of a toothbrush 100 according to an embodiment of the present application. Figure 1-Figure 3As shown, the toothbrush 100 may include:

[0065] A connecting rod 120, the brush head 110 is connected to the connecting rod 120;

[0066] Grip 130;

[0067] A first adjusting member 140, which is disposed on the handle 130, and the first adjusting member 140 rotates the brush head 110 around the axis of the connection between the handle 130 and the first adjusting key;

[0068] The second adjusting member 150 and the second adjusting key are installed on the first adjusting member 140. The end of the connecting rod 120 away from the brush head 110 is connected to the second adjusting member 150. The second adjusting member 150 rotates the brush head 110 around the axis of the connection between the connecting rod 120 and the second adjusting key.

[0069] In this embodiment, the second adjusting member 150 is rotationally adjusted relative to the handle 130 by the first adjusting member 140. During the process of rotating the second adjusting member 150, the first adjusting member 140 limits the position of the second adjusting member 150. The position of the connecting rod 120 relative to the first adjusting member 140 is rotated by the second adjusting assembly, and the position of the connecting rod 120 is limited.

[0070] The first adjusting member 140 and the second adjusting member 150 are provided to facilitate the maximum adjustment of the angles of the connecting rod 120 and the brush head 110, so that the toothbrush 100 can clean the teeth at various angles. At the same time, the first adjusting member 140 and the second adjusting member 150 lock the connecting rod 120 and the brush head 110 to ensure the normal use of the toothbrush 100.

[0071] It should be noted that when the toothbrush 100 is in use, when the hand applies force, the angle of the first adjustment member 140 and the second adjustment member 150 to the brush head 110 will not change;

[0072] like Figure 6 As shown, further, the first adjustment member 140 and the second adjustment member 150 can also be installed on the replacement brush head 110 of the electric toothbrush 100.

[0073] like Figure 1-Figure 3 As shown, in one embodiment,

[0074] The first adjusting member 140 includes:

[0075] A first connecting member 141;

[0076] A fixing block 142, the fixing block 142 has a first through hole 1421 for the first connecting member 141 to partially pass through, and the fixing block 142 is mounted on the handle 130 through the first connecting member 141;

[0077] A rotating block 143 having a second through hole 1431 for the first connecting member 141 to partially pass through, and a second adjusting member 150 is mounted on the rotating block 143;

[0078] Two first gear rings 144 are respectively mounted on opposite sides of the fixed block 142 and the rotating block 143 , and the two first gear rings 144 are meshed.

[0079] In this embodiment, the fixed block 142 and the rotating block 143 are installed on the handle 130 through the first connecting member 141. Part of the first connecting member 141 passes through the first through hole 1421 and the second through hole 1431, and the bottom is threadedly connected to the handle 130, so that the fixed block 142 is engaged with the two first gear rings 144 on the rotating block 143. The centers of the two first gear rings 144 coincide and are both located on the central axis of the first connecting member 141. When a rotational force is applied to the rotating block 143, the rotating block 143 rotates compared to the fixed block 142. When the force is stopped, the two first gear rings 144 are engaged in an arc shape, so that the rotating block 143 is fixed compared to the fixed block 142, so that the position of the brush head 110 is fixed.

[0080] like Figure 1-Figure 3 As shown, in one embodiment,

[0081] The first connecting member 141 includes:

[0082] A first telescopic rod 145, wherein the first telescopic rod 145 has a movable end, and the rotating block 143 rotates around the axis of the first telescopic rod 145;

[0083] A screw rod 146, the screw rod 146 is connected to an end of the first telescopic rod 145 away from the movable end. After the first telescopic rod 145 passes through the first through hole 1421 and the second through hole 1431, it is threadedly connected to the handle 130 through the screw rod 146;

[0084] A first limit block 147, which is mounted on the movable end of the first telescopic rod 145. When the first telescopic rod 145 is mounted on the handle 130, the first limit block 147 is in contact with the rotating block 143;

[0085] The first spring 148 is sleeved on the movable end of the first telescopic rod 145 , one end of the first spring 148 is connected to the first telescopic rod 145 , and the other end is connected to the first limit block 147 .

[0086] In this embodiment, when the first telescopic rod 145 is installed on the handle 130, the first spring 148 is located in the first through hole 1421. When the rotating block 143 rotates, the top end of the first telescopic rod 145 moves, so that the two meshing first gear rings 144 can rotate with each other. When the force applied to the rotating block 143 stops, the first spring 148 applies a pulling force to the first limiting block 147, and the first limiting block 147 tightens the two first gear rings 144 to keep the first gear rings 144 in a meshing state, so that the position of the rotating block is fixed compared to the fixed block 142.

[0087] Furthermore, the size of the first through hole 1421 is smaller than the size of the top of the handle 130, and the size of the second through hole 1431 is smaller than the size of the first limit block 147. Through the first limit block 147 and the top of the handle 130, the two first gear rings 144 on the rotating block 143 and the fixed block 142 are locked under the action of the screw 146. Through the movable end of the first telescopic rod 145 and the arrangement of the first spring 148, when a lateral rotation force is applied to the rotating block 143, it is ensured that the rotating block 143 can rotate relative to the fixed block 142.

[0088] Furthermore, the first connecting member 141 can also be set in the form of a screw 155, which is screwed together with the top thread of the handle 130 to lock the rotating block 143 and the fixed block 142. When the rotating block 143 needs to rotate relative to the fixed block 142, the screw 155 is used to adjust the rotating block 143 so that it can rotate relative to the fixed block 142.

[0089] like Figure 1-Figure 3 As shown, in one embodiment,

[0090] The second adjusting member 150 comprises:

[0091] A second connecting member 151, the connecting rod 120 is installed on the rotating block 143 through the second connecting member 151, the second connecting member 151 horizontally penetrates the rotating block 143, the rotating block 143 has a third through hole 1432 and a fourth through hole 1433, and the connecting rod 120 has a fifth through hole 121;

[0092] Screw 155: After the second connecting member 151 passes through the third through hole 1432, the fourth through hole 1433 and the fifth through hole 121, it is fixed on the rotating block 143 by the screw 155;

[0093] Two second gear rings 156 , the two second gear rings 156 are mounted on the rotating block 143 ;

[0094] Two third gear rings 157 are mounted on the connecting rod 120 , and the second gear ring 156 is meshed with the third gear ring 157 on the corresponding side.

[0095] In this embodiment, the cross-section of the rotating block 143 is an inverted "n"-shaped structure, and the end of the connecting rod 120 away from the brush head 110 is placed inside the rotating block 143. The end of the second connecting member 151 away from the movable end transversely passes through the third through hole 1432, the fourth through hole 1433 and the fifth through hole 121, and is connected to the screw 155. The second connecting member 151 is transversely installed on the rotating block 143, so that the connecting rod 120 is installed on the second connecting member 151.

[0096] like Figure 1-Figure 3 As shown, in one embodiment,

[0097] The second connecting member 151 includes:

[0098] A second telescopic rod 152, the second telescopic rod 152 having a movable end, an end of the second telescopic rod 152 away from the movable end passes through the third through hole 1432, the fourth through hole 1433 and the fifth through hole 121 and is threadedly connected to the screw 155, and the connecting rod 120 rotates around the axis of the second telescopic rod 152 as a circle center;

[0100] The second spring 154 is sleeved on the movable end of the second telescopic rod 152 , one end of the second spring 154 is connected to the telescopic rod, and the other end is connected to the second limit block 153 .

[0101] In this embodiment, when the connecting rod 120 rotates, the action principle of the second telescopic rod 152 is the same as that of the first telescopic rod 145. When the connecting rod 120 rotates, the third gear ring 157 rotates compared with the second gear ring 156. At this time, the movable end of the second retractable rod moves, and the second spring 154 relaxes. When it rotates to an adapted angle, the third gear ring 157 meshes with the second gear ring 156, and the second spring 154 resets, so that the limit block and the screw 155 continue to cooperate, and the third gear ring 157 and the second gear ring 156 are locked, so as to avoid the displacement of the connecting rod 120 and the rotating block 143 during use;

[0102] It should be noted that the size of the third through hole 1432 is larger than the size of the second spring 154 and smaller than the size of the second limit block 153. The size of the fourth through hole 1433 is smaller than the size of the screw 155. The second gear ring 156 is locked with the corresponding third gear ring 157 through the screw 155 and the second limit block 153.
