[0061] As shown in Figure 1 , Figure 2 , Figure 8 , Figure 9 , Figure 11 and Figure 12 , the present application provides a dental floss clamping system of a dental floss stick, comprising:

[0062] a body shell 1;

[0063] a control button 2, the control button 2 is linearly slidingly arranged in the body shell 1, the control button 2 has a dental floss clamping position 21 and a dental floss releasing position 22 which are switched relative to each other under the action of an external force relative to the body shell 1;

[0064] a linkage mechanism 3, the linkage mechanism 3 is arranged in the body shell 1, and the linkage mechanism 3 is drivingly connected to the control button 2;

[0065] two dental floss holders 4, the two dental floss holders 4 are oppositely arranged in the body shell 1, each dental floss holder 4 comprises a first clamping arm 41 and a second clamping arm 42 which are clamped and matched with each other, and at least one of the first clamping arm 41 and the second clamping arm 42 is drivingly connected to the linkage mechanism 3;

[0066] During the sliding of the control button 2 from the dental floss releasing position 22 to the dental floss clamping position 21, the two dental floss holders 4 synchronously or asynchronously clamp a dental floss 5.

[0067] In the present application, the above-mentioned floss stick can be manual or electric. The control button 2 is linearly slidably arranged in the body shell 1, and the linkage mechanism 3 is arranged in the body shell 1 and drivingly connected to the control button 2, so that the linkage mechanism 3 changes its movement with the linear movement of the control button 2. At the same time, the two floss holders 4 are oppositely arranged in the body shell 1 with a spacing adapted to the length of the floss 5 to be clamped. Each floss holder 4 comprises a first clamping arm 41 and a second clamping arm 42 clampingly matched with each other, and at least one of the first clamping arm 41 and the second clamping arm 42 is drivingly connected to the linkage mechanism 3, i.e. the first clamping arm 41 or the second clamping arm 42 is driven to move by the linkage mechanism 3, or both the first clamping arm 41 and the second clamping arm 42 are driven to move by the linkage mechanism 3. When the user needs to replace a new floss 5, the two floss holders 4 clamp a floss 5 synchronously or asynchronously during the sliding of the control button 2 from the floss release position 22 to the floss clamping position 21. Conversely, the two floss holders 4 can also clamp a floss 5 synchronously or asynchronously during the sliding of the control button 2 from the floss clamping position 21 to the floss release position 22.

[0068] Therefore, the floss clamping system of the floss stick of the present application can achieve the purpose of cleaning the interdental space in the form of only consuming the consumables of the floss 5, and the replacement of the floss 5 is fast and the cost of toothpicking is small.

[0069] As shown in Figure 11 and Figure 12 , in order to reduce the transmission structure of the above-mentioned linkage mechanism 3 and floss holder 4, the above-mentioned first clamping arm 41 is fixedly arranged in the body shell 1, and the above-mentioned second clamping arm 42 is rotatably arranged in the body shell 1, one end of the second clamping arm 42 is drivingly connected to the linkage mechanism 3 and the other end forms a clamping matching relationship with the first clamping arm 41. During the sliding of the control button 2 from the floss release position 22 to the floss clamping position 21, or during the sliding of the control button 2 from the floss clamping position 21 to the floss release position 22, the second clamping arm 42 swings relative to the body shell 1 within a preset angle range.

[0070] As shown in Figure 2 , Figure 8 and Figure 9As shown in the figures, in order to simplify the structure of the linkage mechanism 3, the linkage mechanism 3 comprises a push rod 31 and two connecting rods 32 corresponding to the two dental floss holders 4, the push rod 31 is linearly slidably arranged in the machine body shell 1 and connected to the control button 2, one end of each connecting rod 32 is hingedly connected to the first floss clamping arm 41 of the corresponding dental floss holder 4 and is provided with a force block 33 for the second floss clamping arm 42 to obtain torque, the other end of each connecting rod 32 is movably connected to the push rod 31 so that the connecting rod 32 swings under the driving of the push rod 31. Specifically, since the push rod 31 is connected to the control button 2, the push rod 31 and the control button 2 move synchronously. Since one end of each connecting rod 32 is hingedly connected to the first floss clamping arm 41 of the corresponding dental floss holder 4 and is provided with a force block 33 for the second floss clamping arm 42 to obtain torque, and since the first floss clamping arm 41 is fixed relative to the machine body shell 1, the connecting rod 32 swings relative to the machine body shell 1, and the force block 33 moves with the movement of the connecting rod 32. When the position of the force block 33 changes, the force block 33 can apply force to the second floss clamping arm 42 to make the second floss clamping arm 42 rotate, so that the second floss clamping arm 42 forms a clamping cooperation with the first floss clamping arm 41. In addition, the other end of each connecting rod 32 is movably connected to the push rod 31, so that the swinging of the connecting rod 32 and the linear movement of the push rod 31 do not interfere with each other.

[0071] As shown in the figures, Figure 3 , Figure 4 , Figure 8 and Figure 9 Further, in order to realize the movable connection between the connecting rod 32 and the push rod 31, an adaptive joint structure 34 is arranged between the connecting rod 32 and the push rod 31, the adaptive joint structure 34 comprises a waist-shaped hole 341 arranged on the connecting rod 32 and a connecting pin 342 arranged on the push rod 31, the connecting pin 342 passes through the waist-shaped hole 341 and is slidably arranged along the length direction of the waist-shaped hole 341.

[0072] As shown in the figures, Figure 8 and Figure 9 In order to improve the movement smoothness of the push rod 31, the linkage mechanism 3 further comprises a guide groove 35, the guide groove 35 is fixedly arranged on the machine body shell 1 and slidably cooperates with the push rod 31. The guide groove 35 can be separately arranged from the first floss clamping arm 41. As shown in the figures, Figure 5 In order to reduce the number of parts, the two first floss clamping arms 41 and the guide groove 35 are integrally formed.

[0073] During the sliding of the control button 2 from the dental floss clamping position 21 to the dental floss releasing position 22, in order to make the second floss clamping arm 42 and the first floss clamping arm 41 automatically assume an open state, a rotating reset member (not shown) is arranged between the second floss clamping arm 42 and the machine body shell 1.

[0074] AsFigure 6 , Figure 7 , Figure 11 as well as Figure 12 As shown, the second wire clamping arm 42 includes a force-receiving part 421, a second main arm part 422, and a second wire clamping part 423 connected in sequence. The connection between the force-receiving part 421 and the second main arm part 422 is hinged to the housing 1. The force-receiving part 421 is slidably engaged with the force-applying block 33. When the connecting rod 32 swings, the force-applying block 33 pushes against the force-receiving part 421 while simultaneously sliding with it. Since the force-receiving part 421 is part of the second wire clamping arm 42, the second wire clamping arm 42 rotates relative to the housing 1 under the action of the force-applying block 33 until the second wire clamping arm 42 and the first wire clamping arm 41 together clamp the dental wire 5.

[0075] like Figure 10 As shown, to achieve synchronous or asynchronous clamping of a single dental floss 5 by two dental floss holders 4, the force-applying block 33 includes a base circle portion 331 and a lifting portion 332 disposed on the outer peripheral wall of the base circle portion 331. The center line of the base circle portion 331 coincides with the hinge center line of the connecting rod 32 relative to the first floss clamping arm 41. The force-receiving portion 421 includes a base portion 421a and an opening / closing control portion 421b disposed on the base portion 421a. The base portion 421a and the second main arm portion 422 are angled together, and the curved wall of the opening / closing control portion 421b slides and abuts against the lifting portion 332. Since the center line of the base circle portion 331 coincides with the hinge center line of the connecting rod 32 relative to the first floss clamping arm 41, when the connecting rod 32 swings, the base circle portion 331 rotates at a fixed angle. The base portion 421a and the second main arm portion 422 are angled together, for example, as shown in the figure. Figure 11 As shown, the angle between the base portion 421a and the second main arm portion 422 is 90 degrees. The changing trend of the curved wall of the opening and closing control portion 421b determines the swing timing of the second floss clamping arm 42 relative to the first floss clamping arm 41. If the changing trends of the curved walls of the opening and closing control portions 421b of the two second floss clamping arms 42 are consistent, the two floss holders 4 can simultaneously clamp a single floss 5 during the sliding process of the control button 2 from the floss release position 22 to the floss clamping position 21. If the changing trends of the curved walls of the opening and closing control portions 421b of the two second floss clamping arms 42 are inconsistent, the two floss holders 4 can asynchronously clamp a single floss 5 during the sliding process of the control button 2 from the floss release position 22 to the floss clamping position 21.

[0076] As one embodiment of the opening and closing control unit 421b described above: when the curved wall of the opening and closing control unit 421b is approximately arc-shaped (i.e.) Figure 8 , Figure 9 as well as Figure 10The lift 332 abuts one side of the curved wall of the opening / closing control portion 421b when the control button 2 is in the dental floss releasing position 22. The lift 332 abuts the middle of the curved wall of the opening / closing control portion 421b when the control button 2 is in the dental floss clamping position 21.

[0077] To further clamp the dental floss 5, the first clamping arm 41 has a first floss clamping tooth 411, and the second clamping arm 42 has a second floss clamping tooth 424 that meshes with the first floss clamping tooth 411.

[0078] The present application also provides an electric dental flosser that includes the dental floss clamping system of the dental flosser. The clamped dental floss 5 vibrates when the electric dental flosser is in operation.

[0079] In summary, the dental floss clamping system of the dental flosser and the electric dental flosser can achieve the purpose of cleaning the interdental space by consuming only the dental floss, and the dental floss can be replaced quickly and the cost of toothpicking is low. Therefore, the present application effectively overcomes the shortcomings of the prior art and has high industrial utilization value.

[0080] The above embodiments only exemplarily illustrate the principles and effects of the present application, and are not intended to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical ideas disclosed by the present application should be covered by the claims of the present application.
