In addition, since the first plate-shaped structure 121, the second plate-shaped structure 122 and the third plate-shaped structure 123 of the brush head assembly 12 enclose the U-shaped receiving groove 126 for receiving the teeth 20, and the first plate-shaped structure 121, the second plate-shaped structure 122 and the third plate-shaped structure 123 are all provided with the bristles 124, the labial surface 21, the lingual surface 22 and the occlusal surface 23 of the teeth 20 located in the receiving groove 126 can be cleaned simultaneously, so that three surfaces of the teeth can be cleaned without adjusting the angle of the brush head assembly 12, which is beneficial to improving the tooth brushing efficiency and has a better cleaning effect.

In the embodiment, the cross section of the receiving groove 126 is substantially U-shaped, and can receive a row of teeth, and compared to the brush head assembly having an H-shaped cross section for receiving two rows of teeth, the brush head assembly 12 of the electric toothbrush 100 has a smaller volume, and is more convenient to be received in the mouth. When using this electric toothbrush 100, the user can arrange one row of tooth in the storage tank 126 of first subassembly 12 of brushing so as to clean earlier, then this first subassembly 12 of brushing of rethread upset for another row of tooth is arranged in storage tank 126 of first subassembly 12 of brushing so as to clean, that is to say, uses this electric toothbrush 100, only needs to change the direction of first subassembly 12 of brushing and can realize the cleanness to the tooth, and it is convenient and the consuming time of brushing teeth is few.

As shown in fig. 1, the arc-shaped dashed line in fig. 1 shows the arc-shaped swing track at the position of the symmetry axis of the brush head assembly, and the swing direction is shown as the direction x in fig. 1. Optionally, the central angle α of the arc-shaped swing track of the brush head assembly 12 ranges from 2 ° to 10 °, and illustratively, the central angle α of the arc-shaped swing track may be 2 °, 3 °, 4 °, 5 °, 6 °, 7 °, 8 °, 9 °, and so on. The central angle range of the arc-shaped swing track of the brush head assembly 12 is controlled within 2 degrees to 10 degrees, so that the situation that the cleaning effect is not ideal due to the fact that the swing amplitude of the brush head assembly 12 is too small can be avoided, and the situation that the brush head assembly 12 collides with parts (such as lips) except teeth when swinging due to the fact that the swing amplitude of the brush head assembly 12 is too large can be avoided, so that the user experience is not good, and therefore the brush head assembly 12 can give consideration to the cleaning effect on the teeth and the use experience of the user.

In some embodiments, the connection of the third plate-like structure 123 to the first plate-like structure 121 has a notch 125, and/or the connection of the third plate-like structure 123 to the second plate-like structure 122 has a notch 125. In other words, the connection between the third plate-like structure 123 and the first plate-like structure 121 has the notch 125, or the connection between the third plate-like structure 123 and the second plate-like structure 122 has the notch 125, or the connection between the third plate-like structure 123 and the first plate-like structure 121 has the notch 125, and the connection between the third plate-like structure 123 and the second plate-like structure 122 has the notch 125. Thus, the first plate-shaped structure 121 and the second plate-shaped structure 122 are easy to deform relative to the third plate-shaped structure 123, so that the width of the accommodating groove 126 can be adjusted, and when the toothbrush is applied to teeth with different sizes, the bristles 124 can be attached to the teeth 20, so that the toothbrush has a good tooth brushing effect and can meet the use requirements of different users.

Alternatively, the first plate-like structure 121, the second plate-like structure 122 and the third plate-like structure 123 may be integrally formed, and at this time, the material may be removed to make the connection between the third plate-like structure 123 and the first plate-like structure 121 have the notch 125, and/or the connection between the third plate-like structure 123 and the second plate-like structure 122 have the notch 125. Thus, the brush head assembly 12 is easy to manufacture.

Alternatively, the first plate-like structure 121, the second plate-like structure 122, and the third plate-like structure 123 are made of an elastic material, for example, the material of the first plate-like structure 121, the second plate-like structure 122, and the third plate-like structure 123 may be rubber, silicone rubber, or the like. In this way, the first plate-shaped structure 121, the second plate-shaped structure 122 and the third plate-shaped structure 123 may be elastically deformed to a certain extent, so that the width of the receiving groove 126 defined by the first plate-shaped structure 121, the second plate-shaped structure 122 and the third plate-shaped structure 123 may be changed to a certain extent so as to be capable of adapting to teeth of different sizes, so as to meet the use requirements of different users (such as adult users and child users). In addition, the first plate-shaped structure 121, the second plate-shaped structure 122 and the third plate-shaped structure 123 are made of soft materials, so that the oral cavity is not easily scratched when the oral cavity is used.

As shown in fig. 4 and 5, in some embodiments, the driving unit 13 includes a driving part 131, a first transmission member 132, and a second transmission member 133, the driving part 131 is provided in the toothbrush handle 11, the first transmission member 132 is connected to the driving part 131, the first transmission member 132 is located in the toothbrush handle 11, one end of the second transmission member 133 is swingably connected to the toothbrush handle 11, and the other end of the second transmission member 133 is connected to the head assembly 12. The driving member 131 is used for driving the first transmission member 132 to rotate, and the first transmission member 132 is used for driving the second transmission member 133 to swing relative to the toothbrush handle 11, so that the brush head assembly 12 swings relative to the toothbrush handle 11 along with the second transmission member 133. Thus, the driving unit 131 provides a rotational motion and converts the rotational motion of the driving unit 131 into a swinging motion by the first and second transmission members 132 and 133 to swing the brush head assembly 12 with respect to the toothbrush handle 11, and the driving device 13 has a simple structure, low design difficulty, and easy assembly. In addition, since the driving unit 13 drives the brush head assembly 12 to swing with respect to the toothbrush handle 11, the driving unit 13 does not need to use a driving unit (e.g., a cylinder, an electric cylinder, etc.) for outputting a horizontal motion, so that the volume of the toothbrush handle 11 can be reduced, which is advantageous for the compact design of the electric toothbrush 100.

In an alternative embodiment, the handle 11 includes the first receiving cavity 113, and the driving member 131 may be adhered to an inner wall surface of the first receiving cavity 113, so that the driving member 131 is fixed in a simple manner. In another alternative embodiment, a fixing member 114 may be further disposed in the first receiving cavity 113, and the driving member 131 is fixed in the first receiving cavity 113 by the fixing member 114, so that stability of the driving member 131 in the toothbrush handle is improved, and it is avoided that the driving member 131 is unstable in connection with the toothbrush handle 11 and shakes in the toothbrush handle 11 when vibration occurs, so that connection between the driving member 131 and the first transmission member 132 is loosened, or the driving member 131 and the toothbrush handle 11 collide to generate loud noise and damage the driving member 131 due to collision.

Specifically, the fixing member 114 may be a strip-shaped structure, and the fixing member 114 presses the driving part 131 into the first receiving cavity 113, so as to fix the driving part 131. Thus, the fixing member 114 has a simple structure, and can firmly fix the driving part 131 in the first receiving cavity 113.

As shown in fig. 4 to 6, in some embodiments, the first transmission member 132 includes a first shaft body 1321 and a second shaft body 1322, the first shaft body 1321 is connected to the driving component 131, the second shaft body 1322 is connected to an end surface of the first shaft body 1321 facing away from the driving component 131, and an axis of the second shaft body 1322 is not collinear with an axis of the first shaft body 1321. One end of the second transmission member 133 close to the second shaft 1322 is provided with a groove 1331, and one end of the second shaft 1322 away from the first shaft 1321 extends into the groove 1331, the first shaft 1321 is configured to rotate around an axis of the first shaft 1321 under the driving of the driving component 131 to drive the second shaft 1322 to rotate so as to push the second transmission member 133 to swing relative to the toothbrush handle 11. Thus, the first transmission member 132 and the second transmission member 133 have simple structures and simple driving methods, thereby facilitating the manufacturing of the first transmission member 132 and the second transmission member 133 and the assembly of the electric toothbrush 100.

Optionally, the extending of the end of the second shaft 1322 away from the first shaft 1321 into the groove 1331 includes a manner that the outer circumference of the second shaft 1322 abuts against an inner wall surface of the groove 1331, and a distance is provided between the outer circumference of the second shaft 1322 and the inner wall surface of the groove 1331. Which will be described in detail below, respectively.

In a first alternative example, in an initial state of non-driving, the second shaft 1322 extending into the groove 1331 has a gap with the inner wall surface of the groove 1331, so that when the driving member 131 is started, so that the driving member 131 drives the first shaft 1321 to rotate to drive the second shaft 1322 to rotate around the axis of the first shaft 1321, the second shaft 1322 moves towards the inner wall surface of the groove 1331, and when the second shaft 1322 touches the inner wall surface of the groove 1331 and then continues to move towards the inner wall surface of the groove 1331, an urging force is generated on the inner wall surface of the groove 1331, so as to urge the second transmission member 133 to swing relative to the toothbrush handle 11. It will be appreciated that in this example, the oscillating movement of second transmission member 133 is relatively delayed with respect to the rotational movement of second shaft 1322.

In a second alternative example, in an initial state of the electric toothbrush 100, when the driving member 131 is not activated, the second shaft 1322 extending into the groove 1331 abuts against an inner wall surface of the groove 1331, so that when the driving member 131 is activated, the first shaft 1321 is driven to rotate by the driving member 131 to drive the second shaft 1322 to rotate around an axis of the first shaft 1321, and the second shaft 1322 pushes the inner wall surface of the groove 1331 to drive the second transmission member 133 to swing relative to the toothbrush handle 11. That is, the second shaft 1322 may always abut against the groove wall of the groove 1331. Thus, as compared with the first alternative example, it is possible to prevent the second shaft 1322 from rotating about the axis of the first shaft 1321 and touching the groove wall of the groove 1331 to generate noise, and it is possible to effectively push the groove wall of the groove 1331 by the displacement generated by the second shaft 1322 to oscillate the second transmission member 133 with respect to the toothbrush handle 11.

It can be understood that, when the second shaft 1322 extends into the groove 1331 and performs a rotational movement along the axis of the first shaft 1321, the rotational movement generated by the second shaft 1322 can be decomposed into a displacement along the thickness direction of the second transmission member 133 and a displacement along the length direction of the second transmission member 133 (as shown in the thickness direction and the length direction in fig. 6), the displacement along the length direction of the second transmission member 133 generated by the second shaft 1322 is used for driving the second transmission member 133 to swing relative to the toothbrush handle 11, so as to avoid the situation that the second shaft 1322 cannot drive the second transmission member 133 any more due to the second shaft 1322 moving along the thickness direction of the second transmission member 133 and the second shaft 1322 separating from the groove 1331, because, in some embodiments, the second transmission member 133 is a block-shaped structure, and the thickness of the second transmission member 133 is larger than the diameter of the second shaft 1322, a groove 1331 penetrating in the thickness direction of the second transmission member 133 is formed at one end of the second transmission member 133 facing the driving member 131, so that, since the thickness of the second transmission member 133 is greater than the diameter of the first shaft body 1321, displacement of the second shaft body 1322 in the thickness direction of the second transmission member 133 does not cause the second shaft body 1322 to be disengaged from the groove 1331, thereby enabling the second shaft body 1322 to stably drive the second transmission member 133 to swing with respect to the toothbrush handle 11 without vibrating in the thickness direction of the second transmission member 133.

As shown in fig. 6 to 8, in some embodiments, the second transmission member 133 is provided with an arc-shaped slot 1332, the toothbrush handle 11 is provided with the guide posts 115, and the guide posts 115 are slidably connected to the corresponding arc-shaped slots 1332, respectively, so that the second transmission member 133 can be swingably connected to the toothbrush handle 11, and the swing path of the brush head assembly 12 is an arc-shaped swing path. Thus, the second transmission member 133 has a simple structure and is easy to manufacture.

In some embodiments, the second driving member 133 is provided with a plurality of arc-shaped slots 1332, the plurality of arc-shaped slots 1332 are spaced along the length direction of the second driving member 133, the toothbrush handle 11 is provided with a plurality of guide posts 115, and the plurality of guide posts 115 are respectively slidably connected to correspond to the plurality of arc-shaped slots 1332. By providing the plurality of arc-shaped grooves 1332 and the guide posts 115, the stability of the connection of the second transmission member 133 to the toothbrush handle 11 and the stability of the swing of the second transmission member 133 can be improved. Illustratively, second driving member 133 is provided with two arcuate slots 1332, and handle 11 is correspondingly provided with two guide posts 115.

Optionally, a glue reducing groove 1333 is formed at one end of the second transmission member 133 facing the driving member 131, and the glue reducing groove 1333 is formed at the periphery of the arc-shaped groove 1332, so that when the first transmission member 132 drives the second transmission member 133 to swing relative to the toothbrush handle 11, the second transmission member 133 generates a pushing force on the arc-shaped groove 1332, and since the glue reducing groove 1333 is formed at the periphery of the arc-shaped groove 1332, the arc-shaped groove 1332 is more easily deformed, so that the acting force of the first transmission member 132 on the second transmission member 133 is buffered, and the noise generated when the first transmission member 132 drives the second transmission member 133 is reduced.

Since second transmission member 133 is connected to head assembly 12, second transmission member 133 optionally extends at least partially out of first receiving cavity 113 to connect to head assembly 12, thereby facilitating connection of head assembly 12 to second transmission member 133. Of course, in other embodiments, the second transmission element 133 may be disposed in the first receiving cavity 113, and the brush head assembly 12 partially extends into the first receiving cavity 113 to connect to the second transmission element 133.

Optionally, the second transmission member 133 and the brush head assembly 12 may be connected in a plug-in manner, specifically, the brush head assembly 12 further includes a connection portion 127, the connection portion 127 is connected to the first plate-like structure 121 and/or the third plate-like structure 123, one end of the second transmission member 133 close to the brush head assembly 12 and one of the connection portion 127 are provided with a plug-in hole, the other end of the second transmission member 133 close to the brush head assembly 12 and the other end of the connection portion 127 are provided with a plug-in post 1334, and the plug-in post 1334 is plugged into the plug-in hole. Thus, the brush head assembly 12 can be stably connected to the second transmission member 133, so that the brush head assembly 12 is driven to make an arc-shaped swing motion with respect to the toothbrush handle 11 by the second transmission member 133. Illustratively, the connecting portion 127 is provided with a plug hole, and the second transmission member 133 is provided with a plug post 1334.
