[0006] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0007] Optionally, the motion conversion structure includes: A conversion groove, disposed on the pusher member, the conversion groove extending along a second direction perpendicular to the first direction; and An eccentric component is disposed on the pushing member and is offset from the fixed axis. The eccentric component slides in conjunction with the conversion groove.

[0008] Optionally, the axis of the eccentric component is arranged parallel to the fixed axis.

[0009] Optionally, the pusher member has a pusher portion extending into the receiving cavity, the pusher portion being configured to abut against the dental floss and push the dental floss; The height of the pusher section is lower than or equal to the thickness of the dental floss.

[0010] Optionally, the pusher section includes: The contact surface, located on the side of the pusher section facing the outlet, is capable of pushing the dental floss; and A guide surface is located on the side of the pusher section facing away from the outlet and is set at an angle to the first direction, so that the dental floss can pass over the pusher section along the guide surface.

[0014] Optionally, the pushing mechanism further includes an elastic reset member, which drives the pushing mechanism to the initial position.

[0015] Optionally, the elastic reset element is a spring; The elastic reset member is disposed between the housing and the pusher member.

[0016] This utility model discloses a dental floss holder. When a user needs to retrieve dental floss, a rotating drive component rotates around a fixed axis. This rotational motion is converted by a motion conversion structure into a linear movement of a pusher component along a first direction. This causes the pusher component to move from its initial position to its ejection position, thus ejecting the dental floss from the receiving cavity through the outlet. After the dental floss is removed, the pusher component returns to its initial position, completing a single pusher cycle and preparing for the next use. The entire process is automated through mechanical transmission, ensuring a smooth, stable, and controllable floss ejection process. Furthermore, it prevents fingers from touching other unused dental floss when retrieving it, thus avoiding cross-contamination. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] It should be noted that when a component is said to be "connected" to another component, it can be directly connected to the other component or it can be connected to a component in between. When a component is said to be "set on" another component, it can be directly set on the other component or it may be set to a component in between.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] like Figures 1 to 7 As shown, this application provides a dental floss holder 100, including a housing 10 and a feeding mechanism 20. The housing 10 has a receiving cavity 13 for accommodating dental floss and an outlet 14 communicating with the receiving cavity 13. The feeding mechanism 20 is disposed on the housing 10 and configured to push the dental floss in the receiving cavity 13 out through the outlet 14. The feeding mechanism 20 includes a feeding member 22 and a driving member 21. The feeding member 22 is configured to move along a first direction and has an initial position and a push-out position. The driving member 21 is rotatably attached to the housing 10 about a fixed axis. The feeding mechanism 20 also includes a motion conversion structure 23, which is configured to convert the rotational motion of the driving member 21 into the movement of the feeding member 22 along the first direction, so that the feeding member 22 moves from the initial position to the initial position, thereby pushing the dental floss in the receiving cavity 13 out through the outlet 14.

[0023] When a user needs to retrieve dental floss, the drive component 21 rotates around a fixed axis. This rotational motion is converted by the motion conversion structure 23 into linear movement of the pusher component 22 along a first direction. This causes the pusher component 22 to move from its initial position to its ejection position, thus ejecting the dental floss from the receiving cavity 13 through the outlet 14. After the floss is removed, the pusher component 22 returns to its initial position, completing a single pusher cycle and preparing for the next use. The entire process is automated through mechanical transmission, ensuring a smooth, stable, and controllable floss ejection process. Furthermore, it prevents fingers from touching other unused floss while retrieving it, thus avoiding cross-contamination.

[0024] In this embodiment, as Figures 1 to 4 As shown, the structure of the housing 10 is not strictly limited, as long as the housing 10 can form a receiving cavity 13 and an outlet 14, and can support the pushing mechanism 20. The housing 10 also has a mounting cavity 15, in which part of the structure of the pushing component 22, part of the structure of the driving component 21, and the motion conversion structure 23 are located; the mounting cavity 15 isolates and protects the components in the pushing component 22, improving the stability and durability of the pushing component 22 during operation.

[0025] In this embodiment, as Figures 1 to 4As shown, the housing 10 includes an outer shell 11 and an inner shell 12 located within the outer shell 11. The inner shell 12 divides the space within the outer shell 11 to form a receiving cavity 13 and a mounting cavity 15. The inner shell 12 is fixed to the outer shell 11 by screws, welding, or bonding. The outer shell 11 includes a main body 111 and a cover 112. The main body 111 has an opening communicating with the receiving cavity 13. The cover 112 is detachably assembled to the main body 111 by a snap-fit ​​structure or bolts to close the opening. After dental floss is inserted into the receiving cavity 13 through the opening, the cover 112 is fastened to the housing 10, ensuring that the dental floss will not come out during transportation and use, and preventing external contaminants such as dust and moisture from entering, thus maintaining the cleanliness of the storage environment.

[0026] In this embodiment, as Figure 2 and Figure 3 As shown, the receiving cavity 13 has a first wall portion 131, which is located in the inner shell 12 and is planar; the first wall portion 131 is positioned opposite to the opening. The outlet 14 has a second wall portion 141, which is flush with the first wall portion 131, so that when the pusher member 22 moves in the first direction, the dental floss can be smoothly pushed out from the receiving cavity 13 through the outlet 14, avoiding jamming or compression deformation caused by misalignment of the first wall portion 131 and the second wall portion 141; at the same time, the flush first wall portion 131 and the second wall portion 141, in conjunction with the linear movement trajectory of the pusher member 22, can effectively reduce the frictional resistance during the dental floss pushing process and improve the smoothness of operation.

[0027] In this embodiment, as Figure 1 , Figure 2 , Figure 4 as well as Figure 5 As shown, the drive member 21 is rotatably attached to the housing 10. Specifically, the housing 10 has a mounting hole. The drive member 21 has two limiting portions 211 and a connecting portion 212 located between the two limiting portions 211. The two limiting portions 211 are located on both sides of the housing 10, and the connecting portion 212 is located in the mounting hole, so as to realize the rotatable connection between the drive member 21 and the housing 10. The drive member 21 also has a drive handle 213, which protrudes from the outer surface of the housing 10 for easy gripping and force application by the user. When the drive handle 213 is rotated, the drive member 21 rotates smoothly around a fixed axis. The drive portion is fixedly connected to the limiting portion 211 located on the outer side of the housing 10.

[0028] In this embodiment, as Figures 2 to 4 as well as Figures 6 to 7As shown, the pusher member 22 has a pusher portion 221 extending into the receiving cavity 13. The pusher portion 221 is configured to abut against the dental floss and push the dental floss. The height of the pusher portion 221 is lower than or flush with the thickness of the dental floss to avoid interference between the pusher portion 221 and the stacked dental floss layers during movement, ensuring that only a single piece of dental floss is pushed at a time. The first wall portion 131 has a groove 16 for the pusher portion 221 to extend from.

[0029] In this embodiment, as Figures 2 to 4 as well as Figures 6 to 7 As shown, the pusher section 221 includes an abutment surface 222 and a guide surface 223. The abutment surface 222 is located on the side of the pusher section 221 facing the outlet 14 and can push the dental floss. The guide surface 223 is located on the side of the pusher section 221 away from the outlet 14 and is set at an angle to the first direction so that the dental floss can pass over the pusher section 221 along the guide surface 223. After the dental floss is pushed out, the guide surface 223 can guide subsequent dental floss to naturally pass over the top of the pusher section 221 along the guide surface 223, avoiding the pusher section 221 from hooking or getting stuck with the dental floss stack when it retracts.

[0030] In this embodiment, as Figure 2 and Figures 4 to 6 As shown, the motion conversion structure 23 includes a conversion groove 232 and an eccentric member 231. The conversion groove 232 is disposed on the pushing member 22 and extends along a second direction perpendicular to the first direction. The eccentric member 231 is disposed on the pushing member 22 and is offset from the fixed axis. The eccentric member 231 is in sliding engagement with the conversion groove 232. When the driving member 21 rotates around the fixed axis, the eccentric member 231, due to its offset from the fixed axis, forms a circular trajectory with the rotation. At this time, the eccentric member 231 is in sliding engagement with the conversion groove 232 extending along the second direction on the pushing member 22. The rotational motion of the eccentric member 231 is converted into linear movement of the pushing member 22 along the first direction by the constraint of the groove wall of the conversion groove 232. During rotation, the lateral force exerted by the eccentric component 231 on the conversion groove 232 is guided by the groove wall of the conversion groove 232, forcing the pushing component 22 to smoothly advance from the initial position to the ejection position along the first direction; during reverse rotation, the eccentric component 231 guides the pushing component 22 to reset, completing a single pushing cycle. The eccentric component 231 is fixed to a limiting component located within the housing 10; the axis of the eccentric component 231 is parallel to the fixed axis.

[0031] In this embodiment, as Figure 2 and Figure 4As shown, the pushing mechanism 20 also includes an elastic reset member 24, which drives the pushing mechanism 20 to the initial position. After the external force on the driving member 21 is removed, the elastic reset member 24 drives the pushing member 22 to automatically reset from the pushed position to the initial position through its own elastic force, ensuring that the pushing member 22 is accurately returned to its original position after each operation. In addition, the elastic reset member 24 forms an elastic preload on the driving member 21 in the initial position, which effectively suppresses the unexpected displacement of the pushing member 22 caused by vibration or accidental contact, and maintains the long-term working stability of the mechanism.

[0032] In this embodiment, as Figure 2 and Figure 4 As shown, the elastic reset member 24 is located within the mounting cavity 15 and is disposed between the housing 10 and the pusher member 22. The elastic reset member 24 is a spring; one end of the spring is connected to the housing 10, and the other end is connected to the pusher member 22. Specifically, both the inner housing 12 and the pusher member 22 have connecting ears that are hooked to the spring.

[0033] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0034] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
