At the same time, the terms such as "up", "down", "left", "right", "middle" and "one" used in the present specification are only for the convenience of clear description, and are not used to limit the scope of the present application. The change or adjustment of the relative relationship, without substantially changing the technical content, is also considered as the scope of the present application.

[0048] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the present application provides a floss vibration system of an electric flosser, comprising:

[0049] a body shell 1;

[0050] a floss clamping module 2, the floss clamping module 2 comprising a floss clamping body 21 for clamping a floss 4 in a tensioned state and a follow-up groove 22 provided on the floss clamping body 21, the floss clamping body 21 being linearly slidably arranged on the body shell 1, and the extension direction of the follow-up groove 22 being not parallel to the sliding direction of the floss clamping body 21;

[0051] a core module 3, the core module 3 comprising a rotary driving device 31, a rotating wheel 32 connected with the rotary driving device 31, and an eccentric shaft 33 provided on the rotating wheel 32, the eccentric shaft 33 extending into the follow-up groove 22 and being in sliding cooperation with the follow-up groove 22, so as to make the floss clamping body 21 linearly reciprocate relative to the body shell 1.

[0052] In the present application, the above-mentioned movement core module 3 comprises a rotating driving device 31, a rotating wheel 32 connected with the rotating driving device 31, and an eccentric shaft 33 arranged on the rotating wheel 32. The eccentric shaft 33 can be integrally formed on the rotating wheel 32, or the eccentric shaft 33 and the rotating wheel 32 can be two independent parts which can be disassembled. Since the rotating wheel 32 is coaxially connected with the rotating driving device 31 and the axis of the eccentric shaft 33 is parallel to the rotating center line of the rotating wheel 32, when the rotating driving device 31 operates, the eccentric shaft 33 rotates eccentrically. Since the above-mentioned thread clamping body 21 is linearly slidably arranged on the body shell 1 and the following groove 22 is arranged on the thread clamping body 21, the following groove 22 linearly moves synchronously with the body shell 1. Since the extending direction of the following groove 22 is not parallel to the sliding direction of the thread clamping body 21, when the eccentric shaft 33 extends into the following groove 22 and is in sliding cooperation with the following groove 22, every time the rotating wheel 32 rotates one circle, the following groove 22 linearly reciprocates once under the driving of the eccentric shaft 33, so that the thread clamping body 21 linearly reciprocates once, thereby the tooth thread 4 in the tension state clamped by the thread clamping body 21 reciprocates once. Therefore, the vibration frequency of the tooth thread 4 becomes higher with the increase of the rotating speed of the rotating wheel 32, so that the tooth thread 4 continuously reciprocates in a plane, thereby the residual substances in the user's tooth gap can be effectively removed. In addition, it is more important that, compared with the existing electric tooth thread stick which mainly adopts the form of acoustic wave vibration, the electric tooth thread stick of the present application adopts the above-mentioned tooth thread vibration system, the rotating kinetic energy of the above-mentioned rotating driving device 31 can be effectively converted into the vibration of the tooth thread 4, the vibration of the body shell 1 can be effectively avoided, so that the body shell 1 remains in a static state. Compared with the irregular vibration of the tooth thread head in the form of acoustic wave vibration, the vibration plane of the tooth thread 4 driven by the tooth thread vibration system of the present application is consistent with the direction of the plane where the tooth gap is located, which is more conducive to the cleaning of the tooth gap.

[0053] Therefore, the tooth thread vibration system of the electric tooth thread stick of the present application can make the direction of the vibration plane of the tooth thread 4 consistent with the direction of the plane where the tooth gap is located, and can effectively avoid the vibration of the body shell 1, thereby improving the experience of the user's oral cleaning.

[0055] Further, in order to simplify the structure of the mounting integrated frame 311 and facilitate the installation of the motor 312 and the battery 313, the mounting integrated frame 311 comprises a single-side opening warehouse body 311c, the closed side of the warehouse body 311c is symmetrically provided with two clamping bent plates 311d, the clamping bent plates 311d can be integrally formed on the warehouse body 311c, or the clamping bent plates 311d and the warehouse body 311c are two independent parts which can be disassembled, the inner cavity of the warehouse body 311c constitutes the second accommodating cavity 311b, and the space structure defined by the two clamping bent plates 311d constitutes the first accommodating cavity 311a.

[0056] Since the rotating driving device 31 and the rotating wheel 32 are located in different cavities of the body shell 1, in order to improve the water tightness between the rotating driving device 31 and the rotating wheel 32, the movement core module 3 further comprises a sealing piece support 34 and a sealing piece 35, the sealing piece support 34 is sleeved on the rotating driving device 31 and has a central hole allowing the driving end of the rotating driving device 31 to pass through, and the sealing piece 35 is arranged between the sealing piece support 34 and the body shell 1.

[0057] In order to facilitate the control of the rotating driving device 31, the movement core module 3 further comprises a circuit board 36, which is electrically connected with the rotating driving device 31.

[0058] As shown in Figure 2 In order to improve the transmission efficiency between the rotating driving device 31 and the thread clamping module 2, the follow-up groove 22 is arranged on the side of the thread clamping body 21 facing the movement core module 3, the extension direction of the follow-up groove 22 is perpendicular to the sliding direction of the thread clamping body 21, and the extension direction of the follow-up groove 22 is perpendicular to the axial direction of the eccentric shaft 33.

[0063] In summary, the electric toothpick's floss vibration system can make the vibration plane of the floss consistent with the plane direction of the tooth gap, effectively avoid the vibration of the body shell, and improve the user's oral cleaning experience. Therefore, the present application effectively overcomes the various shortcomings in the prior art and has a high industrial utilization value.
