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 picks are tools used in daily oral hygiene to remove food debris from between teeth. Traditional dental floss picks are packaged in boxes or multiple plastic bags. Opening the box or removing the pick from the bag each time you use them can easily expose you to unused picks, which is unhygienic and can lead to bacterial contamination. Therefore, dental floss boxes were developed to store dental floss picks. During use, the box dispenses one pick at a time, improving both hygiene and convenience.

[0003] For example, Chinese patent document CN213130028U discloses a portable dental floss box, including a shell, a sliding component and an elastic element disposed within the shell. The shell has a strip-shaped hole and an opening. The sliding component passes through the strip-shaped hole and extends to the outside of the shell. The sliding component can move along the length direction of the strip-shaped hole. The dental floss stick is disposed between the sliding component and the elastic element, and the dental floss stick is pressed against the sliding component under the elastic action of the elastic element. A push hook is also provided on the side of the sliding component facing the elastic element. The sliding component includes a sliding plate disposed within the shell and a button disposed on the outer surface of the shell. The sliding plate and the button are connected. The sliding plate extends along the length direction of the strip-shaped hole, and the push hook is disposed on the side of the sliding plate opposite to the button. When the sliding component moves to a first position relative to the strip-shaped hole, both the dental floss stick and the sliding component are located inside the shell. When the sliding component moves to a second position relative to the strip-shaped hole, the sliding component slides out through the opening to the outside of the shell, and at the same time, the push hook pushes the dental floss stick closest to the sliding component to slide out through the opening to the outside of the shell. This design makes it easy to carry, prevents contamination of other unused dental floss sticks, and is beneficial for oral hygiene.

[0004] However, the existing dental floss box has the following defects during use: When in use, the sliding plate is extended. Because the slotted hole of the dental floss box is relatively long, it is exposed after the sliding plate is extended. After frequent use for a period of time, on the one hand, dust, dirt and other impurities easily stick to the slotted hole, which can cause the sliding plate to become difficult to slide or even get stuck over time; on the other hand, dust and other contaminants can easily enter through the slotted hole and contaminate the floss picks. Therefore, based on the above factors, the reliability of the dental floss box is ultimately poor. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a dental floss box. The technical problem this invention aims to solve is how to improve the reliability of the dental floss box while ensuring a simplified structure.

[0006] The objective of this utility model can be achieved through the following technical solution: A dental floss box includes a box body with an outlet and a seat cover fixedly connected to the opening of the box body. The seat cover has a strip-shaped hole, and a pusher for pushing out dental floss sticks is slidably disposed in the strip-shaped hole. The seat cover is characterized by having a box cover covering the outer cover, and a thin strip-shaped operating opening communicating with the outside is formed between the two. A disc-shaped drive disk is rotatably connected between the box cover and the seat cover. The drive disk can drive the pusher to slide back and forth by rotating. The drive disk blocks above the strip-shaped hole, and part of the drive disk extends out of the operating opening. The size of the operating opening matches the size of the extended part of the drive disk.

[0007] Unlike existing technologies, this dental floss holder features an additional cover over the seat cover with a slotted hole. This effectively prevents dust, dirt, and other impurities from entering the slotted hole. Furthermore, to facilitate the movement of the pusher, a narrow, open-ended control opening is created between the cover and the seat cover. This means that dust and other impurities must pass through this opening before entering the slotted hole. The narrow opening of the control opening further helps prevent dust and other impurities from entering. Moreover, this invention improves the drive structure, giving it a dustproof function. Specifically, a drive disc is rotatably mounted between the cover and the seat cover, positioned above the slotted hole. Part of the drive disc extends beyond the control opening, the size of which matches the protruding portion of the drive disc. This design allows the drive disc to serve a dual purpose: it not only rotates to drive the pusher back and forth, enabling the floss picks to be dispensed, but also functions as a driving component. Furthermore, it can also act as a shield to block the operating opening and the slotted hole. Since the drive disc is a rotating component and is disc-shaped, it means that whether the floss holder is in use or closed, the drive disc will always be above the slotted hole and block the operating opening, thus effectively preventing dust from entering. Therefore, through the design of the cover and drive disc, dust and other impurities can be effectively prevented from entering the slotted hole from the operating opening. On the one hand, it prevents dirt and grime from accumulating inside the slotted hole, allowing the pusher to slide smoothly along the slotted hole even after long-term use. This avoids problems such as the pusher getting stuck or jammed due to prolonged use, thereby improving the reliability of the floss holder. On the other hand, it also prevents dust from entering the slotted hole during use, ensuring the cleanliness of the floss picks inside the holder, which also improves the reliability of the floss holder. Moreover, this dual-purpose design of the drive disc also saves on parts and ensures a streamlined structure for the floss holder.

[0008] In the aforementioned dental floss box, the lower surface of the drive disc has a columnar transmission pin, and the push block has a strip-shaped sliding hole arranged along the width of the strip hole. The transmission pin passes through the sliding hole and can slide along the inner wall of the sliding hole. Through this transmission structure design of the transmission pin and sliding hole, the rotational motion of the drive disc can be converted into the linear motion of the push block. This allows users to rotate the drive disc to drive the push block to slide back and forth, thereby achieving the output of dental floss sticks. This ensures that the drive disc can be used as a driving component while meeting the aforementioned dustproof design, thus ensuring that the drive disc serves two purposes. Furthermore, the above structural design is simple, thereby ensuring a streamlined design for the dental floss box.

[0009] In the aforementioned dental floss holder, an auxiliary gear is rotatably connected to the upper surface of the seat cover. The outer circumferential surface of the drive disc opposite the auxiliary gear has an arc-shaped rack portion, which meshes with the auxiliary gear. This auxiliary gear design improves the stability of the drive disc's rotation, thereby facilitating stable movement of the pusher and ensuring stable floss output, ultimately enhancing the reliability of the dental floss holder.

[0010] In the aforementioned dental floss holder, the drive disc is rotatably connected to the upper surface of the seat cover. A rotating shaft is fixed to the seat cover, and the drive disc is rotatably connected to the rotating shaft. A torsion spring is sleeved on the rotating shaft, with one end of the torsion spring fixed to the drive disc and the other end fixed to the seat cover. This shaft and torsion spring design allows the drive disc to automatically reset, preventing users from forgetting to return it to its original position and thus improving the reliability of the dental floss holder.

[0011] In the aforementioned dental floss box, one side of the seat cover has an isosceles trapezoidal notch with its long side facing upwards, and the other side of the box cover has an isosceles trapezoidal notch with its long side facing downwards. The positions of notch one and notch two are corresponding, and they are stacked to form the operating opening. Through the shape design of notch one and notch two, notch one facilitates the assembly of the drive disc, and notch two facilitates the assembly of the box cover, thereby improving the assembly efficiency of the dental floss box.

[0012] In the aforementioned dental floss box, an actuating block is fixed to the outer circumferential surface of the drive disc extending from the operating opening. This actuating block design facilitates the operation of the drive disc, thereby improving the ease of use of the dental floss box.

[0013] In the aforementioned dental floss box, the bottom of the box body is provided with a pressing member for pressing down the floss picks. The lower surface of the push block is located inside the box body and has a push hook on its lower surface. The lower surface of the seat cover has a strip-shaped protrusion facing the pressing member. The protrusion is arranged adjacent to the push block, and the outer end of the protrusion extends along the length of the strip-shaped hole to near the output port. The height of the lower surface of the protrusion is between the lower surface of the push block and the lowest part of the push hook. Through this protrusion design, the floss picks stored in the box body, pressed by the pressing member, are pressed against the protrusion, rather than the push block. This prevents the lower surface of the push block inside the box from rubbing against the floss picks during its back-and-forth movement, thus preventing the floss picks from shifting relative to the output port. This ensures that the floss picks can be pushed normally from the output port through the push hook along the designed path, thereby avoiding the floss picks getting stuck or even jammed during output, greatly improving the reliability of the dental floss box.

[0014] In the aforementioned dental floss box, the lower surface of the seat cover has guide plates one and two, spaced apart along the sliding direction of the pusher. Both guide plates one and two extend downwards to near the bottom of the box. Guide plate one has a guide opening one that extends through to the lower end, and guide plate two has a guide opening two that extends through to the lower end. With this guide plate and guide opening design, during use, the two ends of the dental floss stick placed inside the box are respectively positioned within guide opening one and guide opening two. In other words, with this design, under the action of the pressing component, the two ends of the dental floss stick can be pushed upwards one by one onto the protrusion through the guiding action of guide opening one and guide opening two, ensuring that the dental floss stick does not deviate during the pressing movement. This facilitates ensuring that the dental floss stick can be accurately output from the outlet according to the preset path, improving the reliability of the dental floss box.

[0015] In the aforementioned dental floss box, the pusher is H-shaped, and the side of the base cover has a mounting opening adapted to the shape of the pusher. The outer end of the strip-shaped hole extends to the mounting opening and communicates with it. This pusher shape design allows for more stable sliding, thus improving the reliability of the dental floss box. Furthermore, the mounting opening design makes installation of the pusher convenient; simply sliding the pusher into the mounting opening achieves a sliding engagement with the strip-shaped hole.

[0016] As an alternative, in the aforementioned dental floss box, a geared disc with the same rotation center is fixed on the lower surface of the drive disc, and a rack aligned with the length of the slot is fixed on the upper surface of the push block. The geared disc and the rack mesh with each other. This transmission structure design, using a geared disc and rack, converts the rotational motion of the drive disc into the linear motion of the push block. This allows users to rotate the drive disc, causing the push block to slide back and forth, thus outputting the floss picks. This ensures that the drive disc can function as a driving component while meeting the dustproof design requirements, achieving a dual-purpose design. Furthermore, the simple structural design contributes to the streamlined design of the dental floss box.

[0017] Compared with existing technologies, this dental floss box has the following advantages: Through the design of the lid and the dual-purpose drive plate, dust, dirt and other impurities cannot enter the slotted hole, whether the dental floss box is in the normally closed state or in the open state, thus greatly improving the reliability of the dental floss box and the structure is also very simple.

[0027] 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.

[0028] Example 1:

[0029] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, this dental floss box includes a box body 1 with an outlet 1a and a base cover 2 fixedly connected to the opening of the box body 1. The base cover 2 has a strip-shaped hole 2a, and a pusher block 3 for pushing out dental floss picks a is slidably disposed within the strip-shaped hole 2a. A box cover 4 covers the base cover 2, and a thin, strip-shaped operating opening 5 is formed between the two, communicating with the outside. A disc-shaped drive disc 6 is rotatably connected between the box cover 4 and the base cover 2, capable of driving the pusher block 3 to slide back and forth along the strip-shaped hole 2a by rotation. The drive disc 6 blocks above the strip-shaped hole 2a, and part of the drive disc 6 extends out of the operating opening 5. The size of the operating opening 5 matches the size of the extended portion of the drive disc 6, thereby achieving the blocking of the strip-shaped hole 2a and the operating opening 5 by the drive disc 6. A toggle block 10 is fixed on the outer circumferential surface of the drive disc 6 extending out of the operating opening 5.

[0030] More specifically, for example Figure 2 and Figure 3 As shown, the drive disc 6 is rotatably connected to the upper surface of the seat cover 2. A rotating shaft 8 is fixed on the seat cover 2. The drive disc 6 is rotatably connected to the rotating shaft 8. A torsion spring 9 is sleeved on the rotating shaft 8. One end of the torsion spring 9 is fixed to the drive disc 6, and the other end is fixed to the seat cover 2. One side of the seat cover 2 has an isosceles trapezoidal notch 21 with its long side facing upwards, and one side of the box cover 4 has an isosceles trapezoidal notch 41 with its long side facing downwards. The positions of notches 21 and 41 are corresponding, and they are stacked to form the operating port 5. Furthermore, an auxiliary gear 7 is rotatably connected to the upper surface of the seat cover 2. The outer peripheral surface of the drive disc 6 opposite to the auxiliary gear 7 has an arc-shaped rack portion 62, which meshes with the auxiliary gear 7.

[0031] like Figure 4As shown, the lower surface of the drive disk 6 has a columnar transmission pin 61, and the push block 3 has a strip-shaped sliding hole 31 arranged along the width direction of the strip hole 2a. The transmission pin 61 passes through the sliding hole 31 and can slide along the inner wall of the sliding hole 31.

[0032] like Figure 5 , Figure 6 and Figure 7 As shown, the bottom of the box body 1 is provided with a pressing member 11 for pressing the dental floss stick a. In this embodiment, the pressing member 11 is a spring sheet, but a spring can also be used. The push block 3 is I-shaped, and the side of the seat cover 2 is provided with a mounting opening 2b that matches the shape of the push block 3. The outer end of the strip hole 2a extends to the mounting opening 2b and communicates with the mounting opening 2b. The lower surface of the push block 3 is located inside the box body 1 and has a push hook 32 on the lower surface. The lower surface of the seat cover 2 has a protruding strip 22 that protrudes towards the pressing member 11 and is strip-shaped. The protruding strip 22 is arranged adjacent to the push block 3. The outer end of the protruding strip 22 extends along the length direction of the strip hole 2a to a position close to the output port 1a. The height position of the lower surface of the protruding strip 22 is between the lower surface of the push block 3 and the lowest part of the push hook 32. Here, the lowest part refers to the lowest part of the push hook 32 from top to bottom from the bottom surface of the box body 1. The lower surface of the cover 2 has guide plate 1 23 and guide plate 24 arranged at intervals along the sliding direction of push block 3. Guide plate 1 23 and guide plate 24 both extend downward to near the bottom of box 1. Guide plate 1 23 has a guide opening 1 231 that passes through the lower end, and guide plate 24 has a guide opening 241 that passes through the lower end.

[0033] The working principle of this dental floss box is as follows: Box 1 is used to store dental floss picks a. The head of dental floss pick a is located in guide opening one 231, and the tail is located in guide opening two 241. The pressing member 11 presses the dental floss pick a inside the box 1 against the protrusion 22 of the seat cover 2. When it is necessary to take out dental floss pick a, people only need to turn the toggle block 10. The drive plate 6 rotates against the elastic force of the torsion spring 9. With the cooperation of the transmission pin 61 and the sliding hole 31, the rotational motion of the drive plate 6 is converted into the linear motion of the push block 3. The push block 3 slides along the strip hole 2a towards the output port 1a. In this way, the push hook 32 on the push block 3 can push the dental floss pick a out of the output port 1a.

[0034] Example 2:

[0035] The technical solution in this embodiment is basically the same as that in Embodiment 1, except that, as Figure 8 As shown, the transmission structure in this embodiment is different. In this embodiment, a gear disk 12 with the same rotation center is fixed on the lower surface of the drive disk 6, and a rack 13 with the same length direction as the strip hole 2a is fixed on the upper surface of the push block 3. The gear disk 12 and the rack 13 are meshed and connected.
