Description

Technical Field

[0001] This invention relates to the field of household goods technology, specifically a toothpaste dispenser. Background Technology

[0002] With continuous innovation in oral care products, solid toothpaste tablets have gradually entered the market as a new type of oral cleaning product. These toothpaste tablets are in solid tablet form and produce cleaning foam by chewing or mixing with saliva. They have significant advantages such as portability, environmental friendliness, and travel-friendliness.

[0003] Currently, toothpaste tablets are mainly sold in single, individually packaged form. To improve ease of use and reduce packaging material consumption, a roll-type toothpaste tablet product has emerged on the market. This product connects multiple toothpaste tablets sequentially to form a roll, which is then wound into a cylindrical structure, enabling multiple uses.

[0004] In the production of roll-shaped toothpaste sheets, to prevent adjacent sheets from sticking together, a sticker is typically attached to the bottom of the sheet before it is rolled into shape. However, this design still has the following technical drawbacks: 1. Difficulty in dispensing precise amounts: Users cannot accurately control the length of the toothpaste sheet taken out each time, making it difficult to control the amount used. 2. Sticker disposal issues: After removing the toothpaste sheet, the sticker on the bottom needs to be disposed of separately, increasing the number of steps involved and environmental impact.

[0005] Therefore, developing a roll-shaped toothpaste sheet structure that can precisely control the dispensing length and optimize the sticker processing method has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a toothpaste machine that can solve the existing problems and realize quantitative dispensing of toothpaste tablets, while recycling the separated stickers.

[0007] The technical solution of the present invention is to provide a toothpaste dispenser with the following structure: a built-in toothpaste holder, in which toothpaste tablets and stickers are rolled up; the toothpaste dispenser is provided with a toothpaste tablet outlet, a drive button, and a sticker recycling wheel; when the drive button is pressed once, the toothpaste tablet extends out of the toothpaste tablet outlet of the toothpaste dispenser, and the sticker on the bottom separates from the toothpaste tablet and enters the sticker recycling wheel.

[0008] The toothpaste dispenser includes a housing and an inner support. The housing contains a toothpaste holder, and one side of the housing has a toothpaste tablet outlet. A drive button is located on the same side. Inside the housing are a sticker collection wheel, a swing rod, a toothpaste tablet pressing block, and a guide wheel assembly. One end of the swing rod is connected to the sticker collection wheel, driving its rotation. The other end of the swing rod is connected to both the toothpaste tablet pressing block and the guide wheel assembly, driving the toothpaste tablet pressing block to reciprocate up and down and driving the guide wheel assembly to rotate. The toothpaste tablet pressing block is located between the guide wheel assembly and the toothpaste tablet outlet, and its upward movement abuts against any unseparated toothpaste tablets. The sticker moves downwards, moving away from the unseparated toothpaste tube and sticker; the unseparated toothpaste tube and sticker simultaneously exit the toothpaste holder and pass through the guide wheel assembly, while the toothpaste tube pressing block moves upwards to press the toothpaste tube firmly, removing any toothpaste tube protruding from the toothpaste tube outlet; at the same time, the sticker separated from the toothpaste tube is rolled into the sticker collection wheel; external force squeezes the drive button inwards, the top of the swing lever drives the guide wheel assembly, causing the unseparated toothpaste tube and sticker to be pulled out of the toothpaste holder simultaneously, while the toothpaste tube pressing block moves upwards to press the toothpaste tube firmly, removing any toothpaste tube protruding from the toothpaste tube outlet; one end of the swing lever drives the sticker collection wheel to rotate and pull the sticker.

[0009] The connection between one end of the swing lever and the sticker recycling wheel means that the inner support is equipped with a ratchet pair, a first ratchet, a first gear, a second gear, and a first ratchet hook. The outer end of the ratchet pair abuts against the inner wall of the drive button. The first ratchet and the first gear are mounted on the inner support via a first connecting shaft. The second gear is fixed to one end of the sticker recycling wheel. The first ratchet hook is mounted on the inner support via a second connecting shaft. The inner end of the ratchet pair meshes with the first ratchet. The first gear meshes with the second gear. The free end of the first ratchet hook meshes with the first ratchet, enabling unidirectional rotation of the first ratchet. During operation, pushing the drive button inward causes the ratchet pair to move linearly inward and pushes the first ratchet and the first gear. The first gear drives the second gear, thereby driving the sticker recycling wheel to rotate.

[0010] The outer diameter of the first ratchet is smaller than that of the first gear, which reduces the rotation speed of the sticker recycling wheel when the drive button is pushed inward.

[0011] The other end of the swing rod is simultaneously connected to the toothpaste tablet pressing block and the guide wheel assembly. This means that the inner support is equipped with a second ratchet pair, a second ratchet, a third gear, a fourth gear, a fifth gear, and a second ratchet hook. The second ratchet pair is connected to the top of the swing rod. The second ratchet and the third gear are connected via a third connecting shaft. The fourth gear is coaxially connected to a cam, and the fourth gear meshes with the third gear. The fifth gear is fixed to the lower active guide wheel of the guide wheel assembly, and the fifth gear meshes with the third gear. One end of the second ratchet hook is rotatably connected to one end of the third connecting shaft, and its free end meshes with the second ratchet. During operation, the swing rod drives the second ratchet and the third gear to rotate. The third gear simultaneously drives the fourth and fifth gears to rotate. The rotation of the fourth gear drives the cam to rotate, and the rotation of the cam drives the toothpaste tablet pressing block to reciprocate up and down. The rotation of the fifth gear drives the lower active guide wheel of the guide wheel assembly to rotate, for conveying the toothpaste tablet.

[0012] A first torsion spring is connected to the first ratchet hook. One end of the first torsion spring is bent and abuts against the outer side of the first ratchet hook, and the other end abuts against the positioning block of the inner bracket, so that the free end of the first ratchet abuts against the first ratchet. A second torsion spring is connected to the second ratchet hook. One end of the second torsion spring is bent and abuts against the outer side of the second ratchet hook, and the other end abuts against the positioning block of the inner bracket, so that the free end of the second ratchet hook abuts against the second ratchet.

[0013] The swing rod is a lever structure, with its middle serving as a fulcrum and rotatably connected to the inner support. The top of the swing rod is the resistance end, and the bottom end is the power end. A roller is located at the bottom end, and the roller is in rolling connection with the inner side of the drive button. A guide shaft is located on the inner support, below the toothpaste tablet outlet, used to keep the sticker vertically downwards. A guide notch is located in the middle of the swing rod, guiding the sticker coming out of the guide shaft through the guide notch before it is wound into the sticker recycling wheel. A third torsion spring is provided on the swing rod, with one end connected to the inner support and the other end connected to the swing rod, ensuring that the bottom end of the swing rod always abuts against the inner wall of the drive button.

[0014] In addition to the lower active guide wheel, the guide wheel assembly also includes an upper passive guide wheel, and the two rotate in opposite directions; the rotation direction of the drive sticker recycling wheel is the same as the rotation direction of the lower active guide wheel of the guide wheel assembly.

[0015] The toothpaste tablet is movably embedded in the through hole of the mounting base. The mounting base has a channel for the toothpaste tablet to pass through from the guide wheel assembly. The top of the toothpaste tablet extends upward out of the mounting base and is positioned against the toothpaste tablet in the channel. The mounting base is equipped with a return spring for providing downward reset of the toothpaste tablet.

[0016] The first ratchet assembly is elongated and has a straight toothed rack at the top. A rectangular through hole is provided in the middle of the ratchet assembly along the length direction, so that the straight toothed rack has a certain degree of elasticity.

[0017] With the above structure, the present invention has the following advantages: 1. With a simple press of a button, the entire process of feeding toothpaste tablets, fixing and pushing them out, peeling off the backing paper, and recycling the backing paper is completed synchronously and automatically, eliminating the need for users to manually tear, measure length, or dispose of waste stickers.

[0018] 2. Using a swing lever as the core power distribution hub, the single linear thrust from the drive button is efficiently and reliably converted into mechanical work in two directions: one end drives the guide wheel assembly and cam-pressing block mechanism via a ratchet gear set; the other end drives the sticker recycling wheel via another ratchet gear set. This purely mechanical structure is low-cost and highly reliable, ensuring a precise dispensing of one toothpaste tablet per use.

[0019] 3. By pressing the toothpaste tablet firmly at a specific time, in conjunction with the toothpaste tablet outlet structure, a defined and repeatable separation point is formed at the guide shaft, ensuring that the toothpaste tablet can be smoothly removed each time while the sticker is effectively blocked. Guide notches are designed on the guide shaft and swing rod to provide a clear and forced turning path for the peeled sticker, ensuring that it is accurately guided to the collection wheel, preventing accumulation or tangling inside the machine, and guaranteeing long-term stability.

[0020] 4. Under the action of their respective torsion springs, the first and second ratchet hooks ensure unidirectional rotation of the sticker recycling drive chain and the toothpaste delivery drive chain, respectively. This prevents the toothpaste tube from retracting or the sticker from loosening due to reverse movement of the mechanism during button reset, ensuring the effectiveness of each action.

[0021] 5. The toothpaste tablet channel, sticker path, and mechanical transmission area are clearly defined, reducing the risk of internal interference and facilitating troubleshooting. Attached Figure Description

[0033] The invention will now be further described with reference to the accompanying drawings.

[0034] like Figure 1-10 As shown, the toothpaste dispenser of the present invention is a device for holding and dispensing sheet toothpaste. The toothpaste sheets are rolled up at the factory and bonded to a backing sticker to form a "toothpaste sheet roll," which is placed on the toothpaste holder 3 inside the machine. Each time the user uses the device, they simply press the drive button 5 once. This triggers a series of gears, ratchet wheels, and lever mechanisms inside the machine to work in tandem, ultimately achieving: Outputting a new toothpaste sheet: A new toothpaste sheet extends from the toothpaste sheet outlet 4 for the user to take. Peeling off and collecting the backing sticker: The backing sticker separated from the toothpaste sheet is automatically wound onto the sticker collection wheel 6 for centralized storage, keeping the machine's interior clean. The entire process is powered solely by the user's single action of pressing the button, and this action is decomposed and transmitted to various functional components through a mechanical structure.

[0035] like Figure 2As shown, the toothpaste machine of the present invention has a specific structure including an outer shell 1 and an inner support 2. The outer shell 1 is provided with a toothpaste holder 3. One side of the outer shell 1 is provided with a toothpaste sheet outlet 4, and a drive button 5 is provided on the same side. The drive button 5 has two sets of guide rods, and each guide rod has a return spring. When pressed inward, the return spring is squeezed. After the external force is removed, the return spring pushes the drive button to return to its original position.

[0036] like Figure 5 and Figure 6 , Figure 8 and Figure 9 As shown, the outer casing 1 contains a sticker recycling wheel 6, a swing rod 7, a toothpaste tablet pressing block 8, and a guide wheel assembly 9. One end of the swing rod 7 is connected to the sticker recycling wheel 6, driving the sticker recycling wheel 6 to rotate. The other end of the swing rod 7 is simultaneously connected to the toothpaste tablet pressing block 8 and the guide wheel assembly 9, used to drive the toothpaste tablet pressing block 8 to reciprocate up and down and to drive the guide wheel assembly 9 to rotate. The toothpaste tablet pressing block 8 is located between the guide wheel assembly 9 and the toothpaste tablet outlet 4. When it moves upward, it abuts against the unseparated toothpaste tablet and sticker; when it moves downward, it moves away from the unseparated toothpaste tablet and sticker. The toothpaste tube and sticker simultaneously exit from the toothpaste holder 3 and pass through the guide wheel assembly 9. The toothpaste tube pressing block 8 presses the toothpaste tube upward, and the toothpaste tube extending out of the toothpaste tube outlet 4 is removed. At the same time, the sticker that separates from the toothpaste tube is rolled into the sticker recycling wheel 6. External force squeezes the drive button 5 inward, and the top of the swing rod 7 drives the guide wheel assembly 9, so that the toothpaste tube and sticker that have not separated are pulled out from the toothpaste holder 3 simultaneously. At the same time, the toothpaste tube pressing block 8 is driven upward to press the toothpaste tube, and the toothpaste tube extending out of the toothpaste tube outlet 4 is removed. One end of the swing rod 7 drives the sticker recycling wheel 6 to rotate and pull the sticker.

[0037] The connection between one end of the swing lever 7 and the sticker recycling wheel 6 means that the inner support 2 is equipped with a ratchet pair 10, a first ratchet 11, a first gear 12, a second gear 13, and a first ratchet hook 14. The outer end of the ratchet pair 10 abuts against the inner wall of the drive button 5. The first ratchet 11 and the first gear 12 are mounted on the inner support 2 via a first connecting shaft 15. The second gear 13 is fixed to one end of the sticker recycling wheel 6. The first ratchet hook 14 is mounted on the inner support 2 via a second connecting shaft 16. The inner end of the ratchet pair 10 meshes with the first ratchet 11. The first gear 12 meshes with the second gear 13. The free end of the first ratchet hook 14 meshes with the first ratchet 11, enabling unidirectional rotation of the first ratchet 11. During operation, pushing the drive button 5 inward pushes the ratchet pair 10 to move linearly inward and pushes the first ratchet 11 and the first gear 12. The first gear 12 drives the second gear 13, thereby driving the sticker recycling wheel 6 to rotate.

[0038] The outer diameter of the first ratchet 11 is smaller than that of the first gear 12, which reduces the rotation speed of the sticker recycling wheel 6 when the drive button 5 is pushed inward.

[0039] The other end of the swing rod 7 is simultaneously connected to the toothpaste tablet pressing block 8 and the guide wheel assembly 9, meaning that the inner support 2 is equipped with a second ratchet pair 17, a second ratchet 18, a third gear 19, a fourth gear 20, a fifth gear 21, and a second ratchet hook 22; the second ratchet pair 17 is connected to the top of the swing rod 7, the second ratchet 18 and the third gear 19 are connected through a third connecting shaft 23, the fourth gear 20 is coaxially connected to a cam 24, the fourth gear 20 meshes with the third gear 19, and the fifth gear 21 is fixed to the lower active guide wheel of the guide wheel assembly 9. Wheel 21 meshes with the third gear 19. One end of the second ratchet hook 22 is rotatably connected to one end of the third connecting shaft 23, and its free end meshes with the second ratchet 18. During operation, the swing rod 7 drives the second ratchet 18 and the third gear 19 to rotate. The third gear 19 simultaneously drives the fourth gear 20 and the fifth gear 21 to rotate. The rotation of the fourth gear 20 drives the cam 24 to rotate. The rotation of the cam 24 drives the toothpaste tablet pressing block 8 to reciprocate up and down. The rotation rod of the fifth gear 21 drives the lower active guide wheel of the guide wheel group 9 to rotate, which is used to transport toothpaste tablets.

[0040] A first torsion spring 25 is connected to the first ratchet hook 14. One end of the first torsion spring 25 is bent and abuts against the outer side of the first ratchet hook 14, and the other end abuts against the positioning block of the inner bracket 2, so that the free end of the first ratchet 11 abuts against the first ratchet 11. A second torsion spring 26 is connected to the second ratchet hook 22. One end of the second torsion spring 26 is bent and abuts against the outer side of the second ratchet hook 22, and the other end abuts against the positioning block of the inner bracket 2, so that the free end of the second ratchet hook 22 abuts against the second ratchet 18.

[0041] like Figure 7 As shown, the swing rod 7 is a lever structure. The middle of the swing rod 7 is a fulcrum and is rotatably connected to the inner bracket 2. The top end of the swing rod 7 is the resistance end and the bottom end is the power end. The bottom end is provided with a roller 27, which is rolledly connected to the inner side of the drive button 5. A guide shaft 28 is provided in the inner bracket 2. The guide shaft 28 is located below the toothpaste tablet outlet 4 and is used to make the sticker face vertically downward. A guide notch 29 is provided in the middle of the swing rod 7. The sticker coming out of the guide shaft 28 is guided by the guide notch 29 and then rolled into the sticker recycling wheel 6. A third torsion spring 30 is provided on the swing rod 7. One end of the third torsion spring 30 is connected to the inner bracket 2 and the other end is connected to the swing rod 7, so that the bottom end of the swing rod 7 is always in contact with the inner wall of the drive button 5.

[0042] like Figure 10As shown, the guide wheel assembly 9 includes a lower active guide wheel and an upper passive guide wheel, and the two rotate in opposite directions; the rotation direction of the drive sticker recycling wheel 6 is the same as the rotation direction of the lower active guide wheel of the guide wheel assembly 9.

[0043] In this invention, all the rotational central shafts of the toothpaste machine are arranged in parallel. For example: ratchet pair 10, first ratchet 11, first gear 12, second gear 13 and first ratchet hook 14; second ratchet pair 17, second ratchet 18, third gear 19, fourth gear 20, fifth gear 21 and second ratchet hook 22; as well as the active guide wheel and passive guide wheel of the guide wheel assembly, and sticker recycling wheel 6.

[0044] The toothpaste tablet pressing block 8 is movably embedded in the through hole of the mounting base 31. The mounting base 31 has a channel for the toothpaste tablets coming out of the guide wheel assembly to pass through. The top of the toothpaste tablet pressing block 8 extends upward out of the mounting base 31 and abuts against the toothpaste tablet in the channel for positioning. The mounting base 31 is provided with a return spring 32 for providing the toothpaste tablet pressing block 8 to return downward.

[0045] The first ratchet assembly 10 is elongated and has a straight toothed rack at the top. A rectangular through hole is provided in the middle of the ratchet assembly 10 along the length direction, so that the straight toothed rack has a certain elasticity.

[0046] The toothpaste dispenser of this invention is a lever-linkage structure with a swing rod 7 as the central pivot. The swing rod 7 is designed as a lever structure, with its midpoint acting as a fulcrum and hinged to the inner support 2. Its bottom power end is equipped with a roller 27, which rolls in contact with the inner surface of the drive button 5 to reduce friction. Its top resistance end is connected to the second set of ratchet gear mechanisms of the drive guide wheel assembly 9 and the toothpaste tablet pressing block 8. A third torsion spring 30 ensures that the bottom end of the swing rod remains in close contact with the inner wall of the drive button, guaranteeing that the swing rod returns to its initial position after the button is reset.

[0047] Work process: The user presses the drive button 5: the button moves inward.

[0048] The swing lever 7 operates as follows: The inner wall of the button pushes the roller at the bottom of the swing lever, causing the entire swing lever to rotate around the fulcrum, and its top end swings upward accordingly; the top mechanism drives the toothpaste delivery and compression; the top of the swing lever is connected to the second ratchet pair 17; the upward swing of the top end pushes the second ratchet pair, driving the second ratchet 18 and the third gear 19 coaxial with it to rotate unidirectionally; the second ratchet hook 22 and the second torsion spring 26 ensure unidirectionality. The third gear 19 simultaneously engages and drives two gears: driving the fifth gear 21, which directly drives the lower active guide wheel of the guide wheel assembly 9 to rotate. The active wheel cooperates with the upper passive wheel, like paper feeding in a printer, pulling the unseparated "toothpaste tablet-sticker" combination out of the toothpaste roll by a fixed length, completing the delivery.

[0049] The fourth gear 20 drives a cam 24 to rotate coaxially. During the rotation, the outer contour of the cam periodically lifts or releases the toothpaste tablet pressure block 8, causing it to reciprocate up and down within the through hole of the mounting base 31.

[0050] When the front end of the conveyed toothpaste tablet reaches the toothpaste tablet outlet 4, the toothpaste tablet pressing block 8 is precisely lifted to its highest point by the cam. The pressing block moves upward, firmly pressing down on the portion of the toothpaste tablet located below it, which has just emerged from the guide wheel assembly but has not yet reached the outlet, thus "locking" it in place. Since the front end of the toothpaste tablet has already extended beyond the outlet and is fixed behind the pressing block, when the user removes the extended toothpaste tablet by hand, the applied pulling force will cause the toothpaste tablet to separate from the weakly adhesive backing sticker at the guide shaft 28 near the outlet. The sticker, blocked by the pressing block and the outlet structure, cannot be pulled out along with the toothpaste tablet.

[0051] After the sticker separates from the toothpaste tube, it is guided vertically downwards by the guide shaft 28. Its front end is then guided towards the sticker recycling wheel by the guide notch 29 in the middle of the swing rod 7. Simultaneously, when the button is pressed, the bottom power end of the swing rod not only drives the top end but also drives the sticker recycling wheel through the first ratchet gear mechanism: the inner side of the button pushes the first ratchet pair 10, which in turn drives the first ratchet 11 and the first gear 12 to rotate unidirectionally, ensured by the first ratchet hook 14 and the first torsion spring 25. The first gear 12 meshes with and drives the second gear 13, which is directly fixed to one end of the sticker recycling wheel 6, causing the recycling wheel to rotate. The rotation of the recycling wheel generates a winding force, winding the backing sticker section, which has separated from the toothpaste tube and been guided by the guide notch, onto the recycling wheel.

[0052] Reset: The user releases the drive button 5. The button resets outward under the action of the reset spring, and together with the third torsion spring 30 on the swing lever, the button pops outward to reset. The swing lever then returns to its initial position, ready for the next press. The toothpaste tablet press 8 resets downward under the action of the reset spring 32 below it, releasing the pressure on the toothpaste tablet.

[0053] The ratchet hooks in all ratchet mechanisms ensure that the gears can only rotate in one direction when pressed, preventing reverse movement during the reset process from causing the toothpaste tablet to retract or the sticker to loosen. Therefore, during the reset process, no moving parts except the button and the swing lever generate effective drive, and the machine remains in the "one tablet delivered" state.

[0054] To ensure that the sticker is smoothly recycled without breaking, the toothpaste machine of the present invention has a first ratchet 11 with an outer diameter smaller than the first gear 12. This means that there is a process of slowing down and increasing torque from the first ratchet pair to the first gear, so that the rotation speed of the sticker recycling wheel is lower than the direct input speed of the button, and the pulling force is gentler and more controllable.

[0055] Sticker path guidance: The guide shaft 28 and the guide notch 29a on the swing arm together form a forced turning path for the sticker. This ensures that the peeled sticker can be accurately and smoothly guided to the recycling wheel, avoiding scattering or jamming inside the machine.

[0056] The toothpaste tablet clamping block's working logic: The role of the toothpaste tablet clamping block 8 is crucial. Driven by a cam, it operates in a "press and release" motion: "pressing" occurs the instant the toothpaste tablet is delivered to its position and the user takes it, serving to fix it and assist in separation; "releasing" occurs after resetting, clearing the way for the next delivery of toothpaste tablets. Its movement must be precisely coordinated with the conveying action of the guide wheel, which is ensured by the simultaneous driving of the cam and guide wheel by the same set of gears, specifically the third gear.

[0057] Structural flexibility and reliability: The rectangular through hole in the middle of the first ratchet pair 10 gives its straight rack part a certain degree of flexibility, which can better mesh and transmit power, while buffering impact and improving durability.

[0058] In this embodiment, the toothpaste dispenser efficiently converts the user's single linear action of pressing the button into mechanical work in two directions through a main swing lever 7: one end drives the toothpaste tablet conveying and pressing mechanism, and the other end drives the sticker recycling mechanism. All actions are completed synchronously, continuously, and precisely in a single press. Utilizing basic mechanical principles such as levers, ratchet wheels, gears, and cams, it achieves automation and ease of use while ensuring the orderly recycling of stickers.

[0059] The toothpaste dispenser in this embodiment has a casing consisting of a front casing, a middle casing, and a rear casing. The front casing is detachably connected to the front of the middle casing and is divided into upper and lower parts. The rear casing is detachably connected to the back of the middle casing and includes an upper rear casing 33 and a lower rear casing 34. An L-shaped notch is provided on the top left side of the upper rear casing 33 and the bottom left side of the lower rear casing 34. After being fixed to the middle casing, the L-shaped notches of the upper rear casing 33 and the lower rear casing 34 form a groove with the side of the middle casing, facilitating the disassembly of the upper rear casing 33 and the lower rear casing 34 from the middle casing. The inner support 2 is fixed to the middle casing. The top of the upper rear casing 33 is rotatably connected to the top of the inner support 2 via a pivot. When the upper rear casing 33 needs to be opened, it rotates upwards around the pivot. The bottom of the lower rear casing 34 is rotatably connected to the bottom of the inner support 2 via a pivot. When the lower rear casing 34 needs to be opened, it rotates downwards around the pivot.
