The utility model provides a dental floss box, includes casing 1, and casing 1 includes casing 1.1 and base 1.2, goes up casing 1.1 and can dismantle fixedly with base 1.2, just go up casing 1.1 and be provided with the appearance chamber 1.4 that is used for holding the dental floss stick, all be provided with the export 3 that is used for taking out the dental floss stick in the both sides of last casing 1.1 and base 1.2 department of cooperateing.

In order to ensure that the dental floss rod can be better taken out from the outlet 3, a dental floss rod pushing-out component 2 is further arranged in the shell 1. The dental floss rod pushing assembly 2 comprises a pushing sheet 2.4, a guide seat 2.1, a pressing rod 2.2, a movable rod 2.3 and a reset spring 2.5, wherein an installation seat 1.3 is further arranged in the upper shell 1.1, the guide seat 2.1 is fixedly arranged at the upper end part of the installation seat 1.3, a hollow guide post 2.11 is arranged in the guide seat 2.1, and two first inclined teeth 2.12 which are in central symmetry with respect to the axis of the guide post 2.11 are arranged at the lower end of the guide post 2.11. The upper end of the pressure rod 2.2 penetrates out of the upper shell 1.1, the upper end of the pressure rod 2.2 is provided with a pressure cap 4, the lower end of the pressure rod 2.2 is vertically movably arranged in the guide post 2.11, the lower end of the pressure rod 2.2 is also provided with an indexing claw 2.21 matched with the sliding claw sleeve 2.31, the lower end of the indexing claw 2.21 is provided with two corresponding indexing clamping grooves 2.22, the guide post 2.11 is also provided with a vertical limiting groove 2.13, and the pressure rod 2.2 is provided with a limiting strip 2.23 corresponding to the limiting groove 2.13.

The upper end of the movable rod 2.3 is fixedly provided with a sliding claw sleeve 2.31, the upper end of the sliding claw sleeve 2.31 is provided with a second helical tooth 2.32 matched with the first helical tooth 2.12, the lower end of the movable rod 2.3 is also provided with a limiting plate 2.33, a reset spring 2.5 is sleeved at the lower end of the movable rod 2.3, two ends of the reset spring 2.5 are respectively abutted against the bottom of the mounting seat 1.3 and the limiting plate 2.33, and the movable rod 2.3 is tightly pressed by the reset spring 2.5 so that the sliding claw sleeve 2.31 is abutted against the guide post 2.11. A structure similar to an automatic ball-point pen is realized, namely, the sliding claw sleeve 2.31 can be intermittently and rotatably arranged in the guide post 2.11 by pressing the pressing rod 2.2, so that the movable rod 2.3 fixed with the sliding claw sleeve 2.31 can synchronously rotate in the mounting seat 1.3.

What should be mentioned is, for avoiding leading to the dislocation because of factors such as vibrations for the dental floss stick releases subassembly 2 operation card pause, in smooth claw cover 2.31 and the stretch into pressure bar 2.2 are worn out to the upper end of movable rod 2.3, the upper end and the pressure bar 2.2 clearance fit of movable rod 2.3, thereby guarantee movable rod 2.3 and pressure bar 2.2's axiality, reduce the card pause phenomenon.

The lower end of the movable rod 2.3 penetrates out of the bottom of the mounting seat 1.3, the mounting seat 1.3 is close to the upper end face of the base 1.2, the push piece 2.4 is clamped at the lower end part of the movable rod 2.3 and is located between the mounting seat 1.3 and the base 1.2, and the movable rod 2.3 is movably matched with the push piece 2.4 in the vertical direction. The axis of the movable rod 2.3 is a first axis, and the push sheet 2.4 is rotatably arranged at the upper end face of the base 1.2 around the first axis and is used for pushing out the dental floss rod 5 at the outlet 3.

In order to ensure that the push piece 2.4 can reliably push out the dental floss stick 5 stacked in the accommodating cavity 1.4, the push piece 2.4 is provided with a contact area, the distance from the contact area to the first axis is larger than the shortest distance from the dental floss stick to the first axis, and a position is formed in the rotation process of the push piece 2.4 so that the dental floss stick is separated from the contact area. More preferably, the pushing piece 2.4 is designed in a semicircular shape, wherein the semicircular pushing piece 2.4 rotates around the first axis, and the radius of the pushing piece 2.4 is larger than the shortest distance from the dental floss stick to the first axis, so that the pushing piece 2.4 can reliably push out the dental floss stick at the bottommost layer when rotating. Alternatively, the pushing piece 2.4 can be oval, bar, square or X-shaped.

Further, the working process of the present invention is as follows: dental floss bars are respectively stacked and installed on two sides of the upper shell 1.1, which are positioned on the installation seat 1.3, and then are closed through the base 1.2, and the dental floss bars are stacked above the push piece 2.4. When the pressure bar in the cavity 1.4 needs to be taken out, a user presses the pressing cap 4 downwards to enable the pressing rod 2.2 fixed with the pressing cap to synchronously move downwards, meanwhile, the return spring 2.5 is compressed, at the moment, the indexing claw 2.21 presses the sliding claw sleeve 2.31 downwards, and the movable rod 2.3 rotates simultaneously in the process of moving downwards under the coordination of the second helical teeth 2.32; when the user sends the pressing cap 4, the movable rod 2.3 moves upwards under the action of the return spring 2.5, and the second helical tooth 2.32 is matched with the first helical tooth 2.12, so that the sliding claw sleeve 2.31 rotates along the first helical tooth 2.12, and the movable rod 2.3 is driven to move upwards in a synchronous rotation mode. At movable rod 2.3 rotation process, movable rod 2.3 orders about push jack 2.4 and rotates, rotates the process at push jack 2.4 and makes dental floss stick and push jack 2.4 contactless completely owing to there is a position for the dental floss stick that piles up falls into on base 1.2, lies in push jack 2.4 and rotates the place plane, and it offsets with the dental floss stick when push jack 2.4 continues to rotate, thereby releases the dental floss stick from export 3, and the user of being convenient for takes. This design can realize the rotation of push jack 2.4 through vertical pressing to get and use the dental floss stick, avoided traditional design to press through the side and need carry out the situation that the side need use both hands when pressing, especially place the dental floss box on the dining table, the ascending reaction force of exerting with the help of the dining table can realize one-hand operation when vertical direction is pressed.

It is to be understood by those skilled in the art that the embodiments of the present invention shown in the drawings and described above are by way of example only and are not intended to limit the present invention. The objects of the present invention have been fully and effectively accomplished. The functional and structural principles of the invention have been shown and described in the embodiments, and any variations or modifications of the embodiments of the invention are possible without departing from the principles. For example, the push sheet is directly driven to rotate through the rotating rod, and the like without creative labor.
