Description

Technical Field

[0001] This invention belongs to the field of dental floss box technology, and relates to a push-button dental floss box. Background Technology

[0002] Dental floss picks are a very common household dental care product. They can be used as both toothpicks and dental floss, effectively removing plaque, soft deposits, and food debris, thus protecting the gums and reducing damage to teeth and gums. Traditional dental floss boxes come in boxes or bags, requiring the box or bag to be opened each time to remove the floss picks. This means fingers may touch unused floss picks, causing contamination. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems of existing electric dental floss boxes by proposing a dental floss box that automatically ejects one floss stick with each press.

[0004] The objective of this invention can be achieved through the following technical solutions:

[0005] A push-button dental floss box includes a base, a box body, and a receiving seat. The receiving seat is disposed in the inner cavity of the box body and has a receiving cavity for stacking dental floss sticks. The side of the box body has a discharge port communicating with the receiving cavity. The box body also has a lever corresponding to the receiving cavity. The lever is rotatably connected to the box body and can push the dental floss stick in the corresponding receiving cavity out of the corresponding discharge port. The box body is disposed on the base and can move up and down relative to the base. A reset mechanism for controlling the box body to reset after being pressed down and a drive mechanism for controlling the lever to push the floss stick out as the box body is pressed down are provided between the box body and the base.

[0006] In the aforementioned push-type dental floss box, there are at least two receiving cavities, at least two levers and at least two dispensing ports, and the three correspond one-to-one. An intermittent switching mechanism is also provided between the levers and the base. When the box is continuously pressed down, each lever sequentially dispenses floss through the intermittent switching mechanism.

[0007] In the aforementioned push-button dental floss box, the box body includes an outer shell and a partition. The partition divides the inner cavity of the box body into an upper chamber and a lower chamber. The aforementioned receiving seat is disposed in the upper chamber and is fixedly connected to the partition. The lower end of the lower chamber is open and covers the upper end of the aforementioned base. A guide seat is fixedly disposed at the bottom of the partition. A lever is rotatably disposed on the guide seat. A guide post is provided at the end of the lever. A guide groove is opened on the partition. The guide post passes upward through the guide groove and swings back and forth around the guide groove.

[0008] In the aforementioned push-type dental floss box, the driving mechanism includes a push block. The bottom of the guide seat is provided with a guide cavity corresponding to the lever. The push block can rise and fall vertically along the guide cavity. The bottom surface of the lever is provided with an upper helical tooth 1. The top surface of the push block is provided with an upper helical tooth 2 that meshes with the upper helical tooth 1. After the box body is pressed down, the push block rises along the guide cavity and approaches the lever. The tooth surface of the upper helical tooth 2 meshes with the tooth surface of the upper helical tooth 1 and pushes the upper helical tooth 1 to rotate.

[0009] In the aforementioned push-button dental floss box, the reset mechanism includes a reset spring and a reset torsion spring. The reset spring is disposed between the partition and the base and is used to drive the box body to separate and reset from the base. The reset torsion spring is disposed between the lever and the partition and is used to drive the lever to swing and reset.

[0010] In the aforementioned push-type dental floss box, the intermittent switching mechanism includes a lower locking block, which is fixed on the base. The top surface of the lower locking block is provided with a first lower helical tooth, and the bottom surface of the push block is provided with a second lower helical tooth that meshes with the first lower helical tooth. The guide cavity is provided with a first middle helical tooth, and the push block is provided with a second middle helical tooth that meshes with the first middle helical tooth. The tooth surfaces of the first middle helical tooth and the first lower helical tooth are misaligned.

[0011] In the aforementioned push-type dental floss box, the upper oblique tooth 2, middle oblique tooth 2, and lower oblique tooth 2 on the push block are vertically aligned, the number of teeth of the lower oblique tooth 2 and middle oblique tooth 2 is the same, and the number of teeth of the lower oblique tooth 2 and middle oblique tooth 2 is a multiple of the number of teeth of the upper oblique tooth 2, which is consistent with the number of receiving cavities / lever.

[0012] In the aforementioned push-type dental floss box, the positions of the middle helical tooth 1, middle helical tooth 2, lower helical tooth 1, and lower helical tooth 2 are continuously distributed along their respective circumferences. There are intermittent gaps between the positions of two adjacent upper helical teeth 2 / two adjacent upper helical teeth 1. When upper helical tooth 1 is located in the intermittent gap of upper helical tooth 2 (i.e., upper helical tooth 2 is located in the intermittent gap of upper helical tooth 1), after the box body is pressed down, the tooth surface of upper helical tooth 2 is misaligned with the tooth surface of upper helical tooth 1, and the lever does not rotate.

[0013] In the aforementioned push-button dental floss box, the base is provided with several guide posts, and the bottom surface of the partition is provided with several guide sleeves corresponding to the guide posts. The top of each guide post is provided with a boss, and the bottom of each guide sleeve is provided with a limiting plate. Each guide post passes through the limiting plate and is inserted into the inner hole of the corresponding guide sleeve. After the reset spring drives the base to separate and reset from the box body, the lower end face of the boss abuts against the limiting plate to form upper and lower limits.

[0014] In the aforementioned push-button dental floss box, the receiving seat is fastened and fixed to the partition, and a number of limiting blocks are fixedly provided on the partition. The receiving seat has a number of limiting grooves that correspond one-to-one with each limiting block. The limiting block is provided with a barb, and the receiving seat has a locking groove that corresponds to and cooperates with the barb to achieve fastening. The limiting block is inserted into the corresponding limiting groove, and the barb is locked in the corresponding locking groove.

[0015] In one of the aforementioned push-button dental floss boxes, the top of the guide post is provided with a guide ramp that faces the center of the tray.

[0016] Compared with the prior art, the present invention, by pressing the box body, engages the upper helical tooth 2 of one of the push blocks with the upper helical tooth 1 of the corresponding lever, causing the lever to rotate and thus pushing out the dental floss stick in the corresponding receiving cavity of the lever. At this time, the upper helical tooth 2 of the other push block is located in the intermittent space of the upper helical tooth 1 of the corresponding lever, and the lever does not rotate. Therefore, only one dental floss stick is pushed out each time it is pressed. Moreover, through the design of the misaligned tooth surfaces of the middle helical tooth 1 and the lower helical tooth 1, each lever can rotate and push out the dental floss stick in sequence when pressed continuously.

[0028] 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.

[0029] like Figure 1 As shown, the present invention provides a press-type dental floss box, comprising a base 1, a box body 2, and a receiving seat 3. The receiving seat 3 is disposed in the inner cavity of the box body 2, and the receiving seat 3 is provided with a receiving cavity 4 for stacking dental floss sticks. The side of the box body 2 is provided with a discharge port 5 communicating with the receiving cavity 4. The box body 2 is also provided with a lever 9 corresponding to the receiving cavity 4. The lever 9 is rotatably connected to the box body 2 and can push the dental floss stick in the corresponding receiving cavity 4 out from the corresponding discharge port 5. The box body 2 is disposed on the base 1 and can move up and down relative to the base 1. A reset mechanism for controlling the box body 2 to reset after being pressed down and a drive mechanism for controlling the lever 9 to realize the floss pushing action as the box body 2 is pressed down are provided between the box body 2 and the base 1.

[0030] like Figure 2 As shown, there are at least two receiving cavities 4, and at least two of the aforementioned levers 9 and discharge ports 5, with each corresponding to the other. An intermittent switching mechanism is also provided between the levers 9 and the base 1. When the box 2 is continuously pressed down, each lever 9 sequentially dispenses material through this intermittent switching mechanism. In this embodiment, there are two receiving cavities 4, and correspondingly two levers 9 and two discharge ports 5. The two discharge ports 5 alternately dispense dental floss rods. In this embodiment, the first middle oblique tooth 14, the second middle oblique tooth 15, the first lower oblique tooth 16, and the second lower oblique tooth 17 have six tooth positions, while the first upper oblique tooth 12 and the second upper oblique tooth 13 have three tooth positions.

[0031] like Figure 3 As shown, the box body 2 includes an outer shell and a partition 6. The partition 6 divides the inner cavity of the box body 2 into an upper chamber and a lower chamber. The aforementioned receiving seat 3 is disposed in the upper chamber and is fixedly connected to the partition 6. The lower end of the lower chamber is open and covers the upper end of the aforementioned base 1. A guide seat is fixedly provided at the bottom of the partition 6. A lever 9 is rotatably disposed on the guide seat. A guide post 19 is provided at the end of the lever 9. A guide groove 7 is opened on the partition 6. The guide post 19 passes upward through the guide groove 7 and swings back and forth around the guide groove 7.

[0032] like Figure 4 As shown, the driving mechanism includes a push block 10. The bottom of the guide seat has a guide cavity 18 corresponding to the lever 9. The push block 10 can vertically rise and fall along the guide cavity 18. The bottom surface of the lever 9 has an upper helical tooth 12, and the top surface of the push block 10 has an upper helical tooth 13 that meshes with the upper helical tooth 12. After the housing 2 is pressed down, the push block 10 rises along the guide cavity 18 and approaches the lever 9. The tooth surface of the upper helical tooth 13 meshes with the tooth surface of the upper helical tooth 12, pushing the upper helical tooth 12 to rotate. The reset mechanism includes a reset spring and a reset torsion spring. The reset spring is disposed between the partition 6 and the base 1, used to drive the housing 2 to separate and reset from the base 1. The reset torsion spring is disposed between the lever 9 and the partition 6, used to drive the lever 9 to swing and reset.

[0033] like Figure 10 As shown, the intermittent switching mechanism includes a lower locking block 11, which is fixed on the base 1. The top surface of the lower locking block 11 is provided with a lower helical tooth 16, and the bottom surface of the push block 10 is provided with a lower helical tooth 17 that meshes with the lower helical tooth 16. The guide cavity 18 is provided with a middle helical tooth 14, and the push block 10 is provided with a middle helical tooth 15 that meshes with the middle helical tooth 14. Figure 9 As shown, the tooth surfaces of the middle helical tooth 14 and the lower helical tooth 16 are misaligned. The upper helical tooth 13, the middle helical tooth 15, and the lower helical tooth 17 on the push block 10 are vertically aligned. The number of teeth of the lower helical tooth 17 and the middle helical tooth 15 is the same. The number of teeth of the lower helical tooth 17 and the middle helical tooth 15 is a multiple of the number of teeth of the upper helical tooth 13. This multiple is consistent with the number of receiving cavities 4 / lever 9. The positions of the middle helical tooth 14, middle helical tooth 15, lower helical tooth 16, and lower helical tooth 17 are continuously distributed along their respective circumferences. There are intermittent gaps between the positions of two adjacent upper helical teeth 13 / two adjacent upper helical teeth 12. When the upper helical tooth 12 is located in the intermittent gap of the upper helical tooth 13, that is, when the upper helical tooth 13 is located in the intermittent gap of the upper helical tooth 12, after the box body 2 is pressed down, the tooth surface of the upper helical tooth 13 is misaligned with the tooth surface of the upper helical tooth 12, and the lever 9 does not rotate.

[0034] The base 1 is provided with several guide posts 20, and the bottom surface of the partition 6 is provided with several guide sleeves 21 corresponding to the guide posts 20. The top of each guide post 20 is provided with a boss 22, and the bottom of each guide sleeve 21 is provided with a limiting plate 23. Each guide post 20 passes through the limiting plate 23 and is inserted into the inner hole of the corresponding guide sleeve 21. After the return spring drives the base 1 to separate and reset from the box 2, the lower end face of the boss 22 abuts against the limiting plate 23 to form an upper and lower limit. The receiving seat 3 is fixedly fastened to the partition 6. Several limiting blocks 24 are fixed on the partition 6. Several limiting grooves corresponding to each limiting block 24 are opened on the receiving seat 3. Each limiting block 24 is provided with a barb 25, and the receiving seat 3 is provided with a slot that corresponds to and cooperates with the barb 25 to achieve a fastening. The limiting block 24 is inserted into the corresponding limiting groove, and the barb 25 is engaged in the corresponding slot. The top of the guide post 19 is provided with a guide ramp, which faces the center of the tray.

[0035] The working principle of this invention is as follows:

[0036] like Figure 5 and Figure 7 As shown, this is the state of the two levers 9 and their corresponding push blocks 10 before the box body 2 is pressed down. When the box body 2 is pressed down, the box body 2, the receiving seat 3, the partition 6, the guide seat, and the levers 9 descend synchronously towards the base 1. At this time, the push blocks 10 only perform vertical lifting and lowering movements without rotating. When the push blocks 10 touch the levers 9, the tooth surfaces of the upper helical tooth 13 and the upper helical tooth 12 contact and mesh. The levers 9 will rotate along the meshing tooth surfaces as the box body 2 is pressed down, as shown. Figure 6 and Figure 8 As shown, when the lever 9 is rotated to the predetermined position, the upper helical tooth 13 of the push block 10 and the upper helical tooth 12 of the lever 9 are completely overlapped. At this time, the guide post 19 of the lever 9 is just rotated to the inside of the receiving cavity 4.

[0037] Release box 2. Under the action of the return spring, box 2, along with housing 3, partition 6, guide seat, and lever 9, rises synchronously and separates from base 1. The lower locking block 11 separates from the push block 10 under the action of the return spring. At this time, due to the misalignment of the tooth surfaces of the middle helical tooth 14 and the lower helical tooth 16, the push block 10 will rotate 60° along the middle helical tooth 14 of the guide seat. At the same time, the push block 10 also slides to the starting position in the guide seat. At this time, the upper helical tooth 12 of the lever loses the squeezing force of the meshing tooth surface. Under the action of the return spring, lever 9 quickly returns to its original position and rotates to the outside of housing 4, and the dental floss stick is pushed out.

[0038] Press the box body 2 again, and the tooth surface of the upper helical tooth 13 of the push block 10 will be misaligned with the tooth surface of the upper helical tooth 12 of the lever 9, and the lever 9 will not rotate.

[0039] Specific instructions regarding the alternating rotation of the two levers 9: (See below) Figure 5As shown in the diagram, the tooth surface of the upper helical tooth 13 on the left side is offset from the tooth surface of the upper helical tooth 12. The tooth surface of the upper helical tooth 13 on the right side corresponds vertically to the tooth surface of the upper helical tooth 12. After pressing the box body 2, the tooth surface of the upper helical tooth 13 on the right side contacts and engages with the tooth surface of the upper helical tooth 12. Therefore, the lever 9 on the right side will rotate, while the lever 9 on the left side will not rotate. When the box body 2 is pressed down to the correct position, as... Figure 6 As shown, the lever 9 on the left side of the diagram only moves up and down relative to the base 1 without rotating. The first helical tooth 12 is located within the intermittent space of the second helical tooth 13, and the second helical tooth 13 is located within the intermittent space of the first helical tooth 12. The lever 9 on the right side of the diagram is completely aligned with the tooth surface of the push block 10, and the lever 9 rotates to the inside of the receiving cavity 4. After releasing the box 2, the right lever 9 returns to its original position, and the two push blocks 10 rotate 60° respectively, so that the tooth surface of the second helical tooth 13 on the right side is misaligned with the tooth surface of the first helical tooth 12, and the tooth surface of the second helical tooth 13 on the left side corresponds vertically with the tooth surface of the first helical tooth 12. After pressing the box 2, the tooth surface of the second helical tooth 13 on the left side contacts and meshes with the tooth surface of the first helical tooth 12, so the left lever 9 will rotate, while the right lever 9 will not rotate.
