Description

Technical Field

[0001] This utility model belongs to the field of daily necessities technology and relates to a dental floss box. Background Technology

[0002] Dental floss is a tool used in daily oral care to remove food debris from the spaces between teeth. Traditional dental floss is packaged in boxes or multiple plastic bags. Opening the box or removing the floss from the bag each time you use it can easily expose you to unused floss, which is unhygienic and can lead to bacterial contamination. Therefore, dental floss holders were developed to store dental floss. During use, the holder dispenses one floss at a time, improving both hygiene and convenience.

[0003] Existing dental floss boxes, such as the novel dental floss box disclosed in patent literature (authorization announcement number: CN219763600U), include a box body, a pusher plate, and a first reset member. The box body has a cavity for holding dental floss, and the box body has a strip-shaped hole and a floss outlet hole. The pusher plate slides along the strip-shaped hole and has a pusher block located within the cavity. The first reset member is located on the pusher plate and is used to push the pusher plate outwards from the box body. In actual use, this dental floss box has the following shortcomings: When floss needs to be removed, the user overcomes the resistance of the first reset member to move the pusher plate, exposing the strip-shaped hole. At this time, external dust, impurities, and droplets from talking can easily enter the cavity through the strip-shaped hole, contaminating the floss inside. Therefore, although this dental floss box is convenient to operate, it suffers from insufficient hygiene. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a dental floss box. This invention solves the problem of insufficient hygiene in existing dental floss boxes while also improving their reliability.

[0005] The objective of this utility model can be achieved through the following technical solution: A dental floss box, comprising a box body and a dental floss ejector, wherein the side of the box body has a dental floss outlet and the dental floss ejector can be translated in a direction close to or away from the dental floss outlet, the dental floss ejector includes a dustproof plate and a guide support portion protruding downward from the lower side of the dustproof plate, characterized in that the box body is provided with a partition and the partition divides the inner cavity of the box body into an upper dustproof cavity and a lower receiving cavity, the dustproof cavity is a structure with a closed structure on all sides, the top of which has a strip-shaped operating opening that penetrates vertically through the top wall of the box body and the bottom of which has a strip-shaped guide hole that penetrates vertically through the partition, the dental floss ejector is disposed in the dustproof cavity and partially extends upward from the strip-shaped operating opening, the dustproof plate is located below the strip-shaped operating opening and its upper side is abutting against the top wall of the box body, the guide support portion is abutting against the upper side of the partition and partially passes downward through the strip-shaped guide hole.

[0006] This dental floss box divides its interior into an upper dust-proof chamber and a lower receiving chamber by incorporating a partition. The dust-proof chamber has a strip-shaped operating opening at the top for the floss ejector to extend upwards, facilitating its pushing operation. A dustproof plate is machined onto the top of the floss ejector, positioned below the strip-shaped operating opening and with its upper side against the top wall of the box, thus effectively blocking the operating opening and forming the first layer of isolation, preventing external contaminants from entering the box through the operating opening. Because the dust-proof chamber is a completely enclosed structure, with the operating opening only at the top and a strip-shaped guide hole running vertically through the partition at the bottom, the guide hole on the partition is never directly exposed, regardless of the position of the floss ejector. The dust-proof chamber, acting as an intermediate transition space, forms a second layer of isolation; even if contaminants breach the dustproof plate, they can only enter the dust-proof chamber and not directly into the receiving chamber.

[0007] In addition, the floss ejector extends downwards through the strip-shaped guide hole on the partition. This part hooks onto the floss inside the receiving cavity. The floss is then ejected from the cavity through the floss outlet by the translational movement of the ejector, allowing for convenient floss removal. During this process, because the upper side of the dustproof plate is against the top wall of the box, and the guide support is against the upper side of the partition, the partition and the top wall of the box together guide the translational movement of the floss ejector. This improves the stability and accuracy of the ejector's movement, ensuring that the floss ejector accurately targets the floss inside the receiving cavity, achieving stable floss ejection and enhancing the reliability of the floss box.

[0008] Therefore, this dental floss ejector features a double-layered dustproof design, effectively preventing external contaminants from entering the cavity and providing excellent dust protection, thus significantly improving the hygiene of the dental floss box. Furthermore, because the dustproof plate not only prevents dust but also works with the top wall of the box for guidance, it achieves a dual purpose, ensuring both hygiene and reliability.

[0009] In the aforementioned dental floss box, the portion of the floss ejector that extends upwards into the strip-shaped operating opening constitutes the operating section. The dustproof plate is strip-shaped, and both the strip-shaped operating opening and the dustproof plate are positioned along the translational direction of the floss ejector. The length and width of the dustproof plate are greater than the length and width of the strip-shaped operating opening, and the operating section is located in the middle of the dustproof plate. This structure ensures that even with slight positional deviations during the movement of the floss ejector, the strip-shaped operating opening remains blocked by the dustproof plate, thanks to the dustproof plate's greater length and width. Furthermore, because the operating section is positioned in the middle of the dustproof plate, the strip-shaped operating opening remains blocked by the dustproof plate as the floss ejector moves towards or away from the floss outlet, preventing the operating opening from fully opening during movement. This effectively prevents external dust and impurities from entering the dust-proof chamber through the strip-shaped operating opening, achieving a good dustproof effect.

[0010] In the aforementioned dental floss box, the guide support includes a first support wall extending downward from the front side of the dustproof plate, and a second support wall extending downward from the lower side of the dustproof plate located at the rear of the operating section. The guide support is engaged with the upper side of the partition via the lower edges of the first and second support walls. In this structure, the first and second support walls form a two-point support, providing a balanced upward support force for the floss ejector. With the support of the partition, the dustproof plate remains horizontal as the floss ejector moves, ensuring that the upper side of the dustproof plate is close to or against the edge of the strip-shaped operating opening, thus guaranteeing a dustproof effect.

[0011] In the aforementioned dental floss box, a rod-shaped spring mounting portion extends from the second support wall in the direction away from the dental floss outlet. A return spring is fitted onto the spring mounting portion to push the dental floss ejector component towards the dental floss outlet. The rear end of the dustproof plate protrudes relative to the guide support portion and is located above the spring mounting portion. This structure not only ensures that the spring mounting portion has sufficient length for the return spring to be installed, making spring installation convenient, but also provides good installation stability, allowing the return spring to stably push the dental floss ejector component towards translation. Simultaneously, this structure allows for a longer dustproof plate, ensuring that after the dental floss ejector component moves forward and resets, the dustproof plate completely blocks the strip-shaped operating opening, thereby improving dust prevention.

[0012] In the aforementioned dental floss box, the box body includes an inner shell and an outer shell that is fixedly fitted over the inner shell and completely covers it. The lower end of the inner shell is open, and the top forms the partition. The box body employs an inner shell and an outer shell design. The open lower end of the inner shell accommodates the placement of dental floss within the cavity, while the top plate of the inner shell directly forms the partition. This design not only facilitates manufacturing but also ensures the stability of the partition structure. Furthermore, the outer shell completely covers the inner shell, improving overall sealing and further reducing the risk of external contaminants entering the cavity. This results in better dust prevention and enhances the hygiene of the dental floss box.

[0013] In the aforementioned dental floss box, the end of the partition away from the floss outlet has a guide protrusion, and the rear end of the dustproof plate is slidably inserted between the top wall of the box and the guide protrusion. This structure guides and supports the rear end of the dustproof plate, which not only greatly improves the stability of the floss ejector during translation, but also enhances the handling and reliability of the dental floss box. More importantly, even after prolonged use, when the plastic material ages, deforms, or creeps, the rear end of the dustproof plate remains supported by the guide protrusion, preventing it from collapsing and creating gaps, thus ensuring that the dustproof effect is not affected.

[0014] In the aforementioned dental floss holder, the guide protrusion is plate-shaped and perpendicular to the spring mounting portion. A guide recess is formed along the upper edge of the guide protrusion, and the spring mounting portion slides through this recess. The guide recess, located along the upper edge of the guide protrusion, facilitates the insertion of the spring mounting portion, thereby making the installation of the floss ejector convenient. Furthermore, the guide recess not only provides clearance, allowing the floss ejector to move away from the floss outlet, but also guides the spring mounting portion during this translation, enhancing the stability of the floss ejector's movement.

[0015] In the aforementioned dental floss box, the guide support further includes a guide plate. The guide plate is vertically positioned and extends along the length of the strip-shaped guide hole, with its lower edge slidably disposed within the strip-shaped guide hole. In this structure, the bottom of the guide plate slides into the strip-shaped guide hole, allowing the guide hole to guide the movement of the floss ejector, improving the stability and accuracy of the floss ejector's movement. This ensures the floss ejector accurately acts on the floss within the receiving cavity, achieving stable floss ejection and higher reliability.

[0016] In the aforementioned dental floss box, a spring plate with one end pointing upwards is provided at the bottom of the receiving cavity. Dental floss is stacked in the receiving cavity of the box body, and the spring plate pushes the dental floss upwards, so that the uppermost dental floss abuts against the partition, ensuring that one piece of dental floss can be pushed out each time the dental floss ejector is operated.

[0017] Compared with existing technologies, this dental floss box has the following advantages:

[0018] 1. The floss ejector features a double-layered dustproof design, effectively preventing external contaminants from entering the floss box and thus greatly improving its hygiene.

[0019] 2. In this floss box, both ends of the floss ejector are supported and guided, which greatly improves the stability of the floss ejector during translation, thereby improving the operating feel. At the same time, because the bottom of the floss ejector is supported, the floss ejector can still maintain stable translation after the floss box has been used for a long time, giving the floss box the advantage of long service life.

[0020] 3. When assembling this dental floss box, simply place the return spring on the spring mounting part, then place the floss ejector downwards on the partition of the inner shell, then cover the outer shell, and finally cover the bottom cover to complete the assembly of the dental floss box. Therefore, this dental floss box also has the advantage of easy assembly. Attached Figure Description

[0034] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0035] This dental floss box includes a box body 1 with a dental floss outlet 11 on the side and a dental floss ejector 2, such as Figures 1 to 3 As shown, the box body 1 has a horizontal partition 131 inside, which divides the inner cavity of the box body 1 into an upper dust-proof chamber 14 and a lower receiving chamber 15. The dust-proof chamber 14 is a closed structure on all sides, with a strip-shaped operating opening 121 that runs vertically through the top wall of the box body 1 at the top and a strip-shaped guide hole 131a that runs vertically through the partition 131 at the bottom. Specifically, the box body 1 includes an inner shell 13 and an outer shell 12 that is fixedly sleeved on the outside of the inner shell 13 and completely covers the inner shell 13. The bottom of the outer shell 12 has a bottom cover 16, which can be opened to facilitate the insertion of dental floss 5 into the receiving chamber 15. The lower end of the inner shell 13 is open, and the top plate is the aforementioned partition 131.

[0036] like Figure 4 and Figure 5 As shown, a spring plate 4 with one end curving upwards is provided on the bottom surface of the receiving cavity 15. The dental floss ejector 2 is disposed in the dust-proof cavity 14 and can move horizontally in the direction of approaching or moving away from the dental floss outlet 11. Figure 8 and Figure 9As shown, the dental floss ejector 2 includes a dustproof plate 21 and a guide support portion 2a protruding downward from the lower side of the dustproof plate 21. The guide support portion 2a abuts against the upper side of the partition 131, and part of the guide support portion 2a passes downward through the strip-shaped guide hole 131a. Specifically, the part that passes downward through the strip-shaped guide hole 131a is a triangular hook portion 251. The hook portion 251 can hook the dental floss 5 in the receiving cavity 15. By translating the dental floss ejector 2, the dental floss 5 in the receiving cavity 15 is ejected from the dental floss outlet 11, realizing the convenient removal of the dental floss 5. Furthermore, the top of the dental floss ejector 2 has a horizontally positioned dustproof plate 21 located below the strip-shaped operating opening 121. An operating part 22 extending upwards from the center of the dustproof plate 21 into the strip-shaped operating opening 121 is provided. The top wall of the housing 1 and the dustproof plate 21 are parallel to each other, and the upper side of the dustproof plate 21 abuts against the top wall of the housing 1, thus blocking the strip-shaped operating opening 121. The way the upper side of the dustproof plate 21 abuts against the top wall of the housing 1 can be as follows: Figure 5 The large area of ​​contact shown is shown. Alternatively, the lower side of the top wall of the box 1 can protrude at the edge of the strip-shaped operating opening 121, and the upper side of the dustproof plate 21 can only contact the edge of the strip-shaped operating opening 121.

[0037] like Figure 4 , Figure 5 and Figure 7 As shown, the strip-shaped operating port 121 is a strip-shaped hole. The length direction of both the strip-shaped operating port 121 and the dustproof plate 21 is set along the translation direction of the toothed wire ejector 2. The length and width of the dustproof plate 21 are both greater than the length and width of the strip-shaped operating port 121.

[0038] like Figure 5 and Figure 9 As shown, the guide support 2a includes a first support wall 23 extending downward from the front side of the dustproof plate 21, and a second support wall 26 extending downward from the lower side of the dustproof plate 21 located at the rear side of the operating part 22. The guide support 2a abuts against the upper side of the partition 131 through the lower edges of the first support wall 23 and the second support wall 26. Figure 7 and Figure 9 As shown, the guide support part 2a also includes a guide plate 25, which is vertically arranged and extends along the length direction of the strip guide hole 131a. The lower edge of the guide plate 25 is slidably disposed in the strip guide hole.

[0039] Combination Figure 6 , Figure 9 and Figure 10As shown, a rod-shaped spring mounting portion 24 extends from the support wall 26 in the direction away from the dental floss outlet 11. The end of the partition 131 away from the dental floss outlet 11 has a guide protrusion 132. The guide protrusion 132 is plate-shaped and perpendicular to the spring mounting portion 24. A guide recess 133 is formed on the upper edge of the guide protrusion 132. The spring mounting portion 24 passes through the guide protrusion 132 and slides within the guide recess 133. A return spring 3 is fitted onto the spring mounting portion 24. One end of the return spring 3 abuts against the support wall 26, and the other end abuts against the guide protrusion 132. Figure 5 and Figure 6 As shown, the rear end of the dustproof plate 21 protrudes relative to the guide support part 2a and is located above the spring mounting part 24. The rear end of the dustproof plate 21 is slidably inserted between the top wall of the box body 1 and the guide protrusion 132. This structure guides and supports the rear end of the dustproof plate 21, thereby preventing it from collapsing downward and creating gaps, and ensuring that the dustproof effect is not affected.

[0040] The following is a brief introduction to how to use this dental floss box:

[0041] First, dental floss 5 needs to be inserted into the dental floss holder, so that the dental floss 5 is stacked in the receiving cavity 15, as follows. Figure 12 As shown, the spring plate 4 on the bottom cover 16 pushes the dental floss 5 upward, so that the uppermost dental floss 5 abuts against the lower side of the partition 131.

[0042] When you need to remove dental floss 5, if Figure 12 As shown, when the floss ejector 2 is moved away from the floss outlet 11, the triangular hook 251 on the bottom surface of the floss ejector 2 will pass over the head of the floss 5, so that the head of the floss is located on one side of the hook 251. Then, the floss ejector 2 is released, and the floss ejector 2 moves towards the floss outlet 11 under the action of the return spring 3, thereby using the hook 251 to push the uppermost floss 5 in the receiving cavity 15 out of the floss outlet 11. At this time, the floss ejector 2 returns to its original position. Figure 5 The state shown. When it is necessary to remove dental floss 5, simply move the floss ejector 2 again.
