Wire-changing tooth pick

Abstract

A tooth pick with a changeable thread. A J-shaped support arm is connected to a wire box, a wire groove provided on the support arm is connected to the wire box, and two left and right bosses are provided at the left and right ends of the bottom plate of the wire box. A wire wheel is provided in the wire box, and the dental floss in the wire wheel enters the wire box through the lower left boss in the wire box and the wire groove on the support arm, and finally passes through the wire outlet hole provided on the lower right boss to pass through the wire box. A cover plate is connected to the wire box through a rotating shaft, and two left and right upper bosses are provided on the cover plate. When the cover plate is opened, the upper boss on the cover plate can cooperate with the lower boss in the wire box to fix the dental floss between the elbow end of the support arm and the wire box for use. When the cover plate is rotated and the four left and right upper and lower bosses are separated, the purpose of replacing the dental floss can be achieved by pulling the thread end outside the wire box. When the cover plate is closed, the upper boss on the cover plate will cooperate with the lower boss in the wire box again to fix the dental floss, and thus it is convenient to cut off the waste dental floss through the wire breaking pile provided on the wire box.

Description

Technical Field

[0001] The invention relates to a teeth picking device, in particular to a tooth picking device capable of continuously changing dental floss. Background Art

[0002] Currently, the known tooth picking devices are toothpicks and dental floss sticks. However, toothpicks and dental floss sticks can only be discarded and thrown away after being used several times. Therefore, using traditional tooth picking devices is both resource-consuming and environmentally unfriendly. Summary of the invention

[0003] In order to overcome the shortcomings of existing tooth picking devices that are both resource-consuming and environmentally unfriendly, the present invention provides a tooth picking device with a replaceable wire. The tooth picking device can set the dental floss roll in a wire box on the tooth picking device, thereby saving resources and protecting the environment by retaining the tooth picking device and only replacing the dental floss.

[0004] The technical solution adopted by the present invention to solve its technical problem is: the present invention includes a cover plate, a wire cover, a wire breaking pile, a clamping ring, a wire box, a support arm, a limit key, an upper boss, a rotating shaft, a wire groove, a bushing, a wire wheel, a keyway, a gear ring, a lower boss, a guide groove and a dental floss.

[0005] The wire box is a circular barrel structure. A shaft sleeve is coaxially arranged at the position of the center hole of the bottom plate of the wire box. A key slot is provided on the inner wall of the shaft hole of the shaft sleeve. The key slot is a semicircular groove. The retaining ring is connected to the bottom plate of the wire box. The retaining ring, the barrel wall and the bottom plate of the wire box together form an annular guide groove. The support arm is a J-shaped rod structure composed of a straight rod and a bent rod. A J-shaped wire groove is provided on the plane of the support arm. The wire groove is an anti-drop groove structure. The support arm is parallel to the wire box and is connected to the left barrel wall of the wire box through the end of the straight rod. The wire groove on the support arm is connected to the guide groove in the wire box. The wire groove port on the bent rod of the support arm corresponds to the notch provided on the right barrel wall of the wire box. Two left and right lower bosses are respectively provided on the groove bottom plates at the left and right ends of the guide groove. The lower boss is a conical platform structure. A wire outlet hole is provided on the right lower boss, which vertically penetrates the right lower boss and the bottom plate of the wire box. The wire breaking pile is vertically connected to the outer surface of the bottom plate of the wire box, and the wire breaking pile is composed of a blade and a safety helmet arranged on the outer end of the blade. The wire wheel is arranged in the gear ring and connected to the sleeve through the wheel hub. The dental floss is wound on the wire wheel. The end of the dental floss passes through the notch on the gear ring and passes through the guide groove, the lower left boss, the wire groove, the notch on the wall of the wire box barrel, the guide groove, the lower right boss, and then passes through the wire outlet hole. The cover plate is a flat plate structure that matches the plane shape of the wire box and the support arm. The lower end of the cover plate is provided with a rotating shaft, a limit key and left and right upper bosses that match the upper sleeve of the wire box, the key slot and the left and right lower bosses. The upper end of the cover plate is provided with a wire cover corresponding to the dental floss between the port of the upper wire groove of the support arm and the notch on the wall of the wire box barrel. The wire cover is a concave groove structure, and the left and right upper bosses are conical platform structures. The rotating shaft on the cover plate is connected to the shaft hole of the upper sleeve of the wire box and is locked by a snap ring. The limit key on the rotating shaft matches the key slot on the sleeve.

[0006] Turn the cover to open. When the cover and the wire box are positioned by the limit key and the key slot, the left and right upper bosses on the cover will respectively cooperate with the left and right lower bosses on the wire box to clamp the dental floss on the left and right sides of the guide groove, thereby fixing the exposed dental floss between the end of the support arm bend rod and the wire box for use.

[0007] The cover plate is rotated to separate the left and right upper bosses from the left and right lower bosses, and the waste dental floss can be pulled out through the dental floss end located on the outside of the wire box. When the cover plate is closed and the dental floss is fixed through the cooperation of the left and right upper bosses and the left and right lower bosses, the excess dental floss can be cut off through the wire cutting piles on the wire box.

[0008] The closed cover plate will cover the wire groove on the support arm and at the same time cover the exposed dental floss between the end of the support arm curved rod and the wire box through the wire cover.

[0009] The beneficial effect of the present invention is that the dental floss roll is arranged in the wire box on the tooth pick, and the tooth pick is retained and only the dental floss is replaced, thereby achieving the purpose of saving resources and protecting the environment.
