[0036] When the dental floss holder 2 is forced to rotate from the storage state to the pop-up state, the rotating part 23 drives the first wheel body 31 and the second wheel body 32 to rotate together through the matching of the first matching part 234 and the first matched part 310 and the matching of the second matching part 235 and the second matched part 320. Since the first wheel body 31 and the second wheel body 32 are rotatably connected, they can rotate synchronously, thereby realizing the retraction of the second dental floss while the first dental floss is being released.

[0037] Specifically, the first matching part 234 is arranged in the form of a pawl, the first matched part 310 is arranged in the form of a ratchet wheel; the second matching part 235 is arranged in the form of a ratchet wheel, the second matched part 320 is arranged in the form of a pawl, or in this embodiment, the first matching part 234 is arranged in the form of a ratchet wheel, the first matched part 310 is arranged in the form of a pawl; the second matching part 235 is arranged in the form of a pawl, the second matched part 320 is arranged in the form of a ratchet wheel. When the rotating part 23 of the dental floss holder 2 rotates in the direction indicated by the arrow Figure 5 , the first matching part 234 drives the first matched part 310 to rotate, and the second matching part 235 drives the second matched part 320 to rotate; when the first matching part 234 rotates in the direction indicated by the arrow Figure 5When the first engaging portion 234 and the second engaging portion 235 are rotated in the opposite direction as indicated by the arrow, the first engaging portion 234 does not push the first engaged portion 310 to rotate, and the second engaging portion 235 does not push the second engaged portion 320 to rotate.

[0038] Further, the dental floss device 1 further comprises an operating assembly 8 for enabling the dental floss holder 2 to be ejected from the box body 4 under the pressing force, and for enabling the dental floss holder 2 to be locked when the dental floss holder 2 is rotated to the position accommodated by the box body 4. Specifically, the operating assembly 8 comprises an operating member 81 exposed through the bottom plate 422 of the bottom box 42 and engaged with the bottom box 42, a blocking portion 83 driven by the operating member 81 to move in the direction intersecting the longitudinal direction under the force, and an operating reset member 82 for enabling the operating member 81 to return to the initial state under the force. The dental floss holder 2 is provided with a blocked portion 236 arranged on the rotating portion 23, which cooperates with the blocking portion 83 to prevent the dental floss holder 2 from being rotated to the ejection direction and ejected under the action of a rotating reset member described below when the dental floss holder 2 is rotated to the position accommodated by the box body 4.

[0039] Further, the dental floss device 1 further comprises a rotating reset member (not shown in the figure), which has a tendency to drive the dental floss holder 2 to rotate to the ejection direction when the dental floss holder 2 is in the accommodation state. Specifically, the rotating reset member accumulates potential energy when the dental floss holder 2 is rotated from the ejection state to the accommodation state. When the dental floss holder 2 is accommodated by the box body 4, the cooperation between the blocking portion 83 and the blocked portion 236 prevents the rotating reset member from releasing the potential energy. When the operating member 81 is forced to move the blocking portion 83, the blocking portion 83 no longer blocks the rotation of the dental floss holder 2 in the transverse direction. At this time, the rotating reset member releases the potential energy and overcomes the resistance caused by the cooperation between the limiting member 7 and the limited member 34 described below, thereby driving the dental floss holder 2 to be ejected from the box body 4. In this embodiment, the rotating reset member can be arranged as a torsion spring.

[0040] The dental floss device 1 further comprises a limiting piece 7, the floss supply assembly is provided with a limiting piece 34, the limiting piece 34 is arranged on the second wheel body 32 or the first wheel body 31, and the embodiment is described by taking the case that the limiting piece 34 is arranged on the second wheel body 32 as an example: in the transverse direction, the limiting piece 34 is arranged on the second wheel body 32, close to one side of the bottom box bottom plate 422 of the bottom box 42, and the limiting piece 7 is arranged between the bottom box bottom plate 422 and the limiting piece 34. The limiting piece 7 and the limiting piece 34 are matched with each other and have the effect of hindering the dental floss holder 2 from rotating in the ejection direction; after the dental floss holder 2 is switched from the storage state to the ejection state, the limiting piece 7 and the limiting piece 34 are matched with each other and prevent the dental floss holder 2 from continuing to rotate in the ejection direction; it should be noted that, at this time, the limiting piece 7 and the limiting piece 34 are matched with each other and do not hinder the dental floss holder 2 from rotating in the storage direction. The limiting piece 7 is further connected with a first reset piece 9, and the first reset piece 9 is used to restore the limiting piece 7 and the limiting piece 34 to the state of being matched with each other after the limiting piece 7 and the limiting piece 34 are disengaged.

[0041] Specifically, the limiting piece 7 is provided with a ratchet wheel, the limiting piece 34 is also provided with a ratchet wheel, and the two are matched through the ratchet wheels.
