A paper roll case

Abstract

This invention belongs to the technical field of household appliances, and particularly relates to a toilet paper dispenser. The dispenser's cover is located outside the paper compartment and can rotate between covering and revealing the paper dispensing opening. A pair of closures are connected to both ends of the cover, and a hanging shaft is connected to both ends of the closures, enabling linkage between the cover and the hanging shaft via the closures. When the cover is rotated downwards to change from covering the paper dispensing opening to revealing it, the cover, via the closures, rotates the hanging shaft to release paper, causing the roll of paper to accumulate at the paper dispensing opening. Simultaneously, the closures accumulate force. The accumulated force of the closures drives the hanging shaft to rotate and retract the paper, causing the roll of paper to retract into the paper compartment. At the same time, the closures drive the cover to rotate upwards to change from revealing the paper dispensing opening to covering it. Therefore, when dispensing paper, the cover can be rotated downwards. After dispensing, the used roll of paper exposed outside the paper compartment can be retracted into the paper compartment, and the paper dispensing opening is automatically closed, effectively preventing moisture intrusion.

Description

Technical Field

[0001] This invention belongs to the field of household goods technology, and in particular relates to a toilet paper roll box. Background Technology

[0002] Toilet paper holders are common necessities in daily life, used to hold and store toilet paper rolls for convenience. With rising living standards and increased emphasis on health and hygiene, the functions and types of toilet paper holders are constantly expanding. For ease of dispensing, toilet paper holders typically have an open dispensing slot, and one side is often serrated to facilitate cutting the toilet paper.

[0003] However, bathrooms are humid environments, and the open toilet paper dispenser exposes the toilet paper to damp air for extended periods, making it highly susceptible to moisture and mold. Furthermore, the paper roll rotates continuously when pulled out, requiring the other hand to hold one end steady to break it. This results in unused paper protruding from the dispenser, causing soiling and waste. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a toilet paper box, thereby solving the technical problems of open paper dispensing opening causing the toilet paper to be exposed to humid air and become damp and moldy, and the exposed unused toilet paper after a break will be soiled and wasted.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0008] This invention provides a paper roll box, including a paper storage compartment, a cover, a closure device, and a hanging shaft. A paper dispensing opening is located on the lower front of the paper storage compartment. The cover is positioned outside the paper storage compartment and can rotate between covering and revealing the paper dispensing opening. A pair of closure devices are installed on the inner walls of both sides of the paper storage compartment. Each pair of closure devices passes through the side wall of the paper storage compartment on its respective side and connects to both ends of the cover. Both ends of the hanging shaft are connected to the two closure devices, allowing the cover and the hanging shaft to be linked via the closure devices. When the cover is rotated downwards to change from covering the paper dispensing opening to revealing it, the cover rotates via the closure device and the hanging shaft to release paper, causing the roll of paper to accumulate at the paper dispensing opening. Simultaneously, the closure device stores force. When the stored force of the closure device drives the hanging shaft to rotate and retract the paper, causing the roll of paper to retract back into the paper storage compartment, the closure device drives the cover to rotate upwards to change from revealing the paper dispensing opening to covering it.

[0009] Furthermore, the closure includes a base, a gear set, and a latch, with the base and latch engaging to form an inner cavity for accommodating the gear set. The gear set includes a drive gear, a power spring, an escapement mechanism, a ratchet, and a locking lever, all mounted on the base. The drive gear includes a torsion spring and a first gear coaxially fixed. The first gear has a locking tongue, and the torsion spring is fixed to the base. The torsion spring begins to store power when the first gear rotates, causing the first gear to tend to move in the opposite direction. The power spring includes a mainspring and a second gear coaxially fixed. The second gear has a lever, and the mainspring begins to store power when the second gear rotates, causing the second gear to tend to move in the opposite direction. The opposite motion trend; the escapement mechanism includes an escape wheel and an escape fork that cooperate with each other. The escape fork engages with the lever through the fork head. A pull wheel is coaxially mounted on the escape wheel, causing the pull wheel to rotate at a constant speed. The ratchet simultaneously meshes with the first gear and the second gear to drive the rotation between the power gear and the mainspring in one direction. When the power gear rotates, it can drive the mainspring to rotate, but when the mainspring rotates, it will not drive the power gear to rotate. The locking lever includes a lever and a spring. The two ends of the spring are connected to the base and the lower end of the lever, respectively. The lower end can be pressed down by the pull wheel. The other end of the lever is provided with a hook that can engage with the locking tongue.

[0010] Furthermore, rotating shafts are provided on both sides of the cover plate; the gear shaft of the first gear passes through the cover and the paper loading compartment in sequence and is connected to the rotating shaft, so that the cover plate and the power gear rotate synchronously; the gear set also includes a transmission gear and an idler gear set on the base, the transmission gear meshes with the power gear through the idler gear, so that the transmission gear and the power gear move in the same direction; the gear shaft of the transmission gear passes through the base and is connected to a fixed disk, the fixed disk having a first magnet embedded in it; rotating disks are provided at both ends of the hanging shaft, the rotating disks having a second magnet embedded in them, the second magnets at both ends attracting the corresponding first magnets respectively, so that the hanging shaft and the transmission gear rotate synchronously, thereby causing the cover plate and the hanging shaft to move together.

[0011] Furthermore, locking hooks are provided on both sides of the cover, and locking buckles corresponding to the locking hooks are provided on both sides of the base. The cover and the base are fastened together by locking the locking hooks and locking buckles.

[0012] Furthermore, a pair of latches and positioning strips are provided on the inner walls of both sides of the paper loading compartment. The pair of latches and positioning strips on the same side form the installation position of the closure device on the same side in the paper loading compartment. Locking tongues are provided on both sides of the base. The closure device is supported on the positioning strips, and the two locking tongues cooperate with a pair of latches to install the closure device in the installation position.

[0013] Furthermore, the hanging shaft includes two interlocking first cylindrical bodies and second cylindrical bodies. A mounting platform is horizontally arranged inside the first cylindrical body at the central axis. Fixing strips are installed on the upper and lower parts of the mounting platform by springs. After the first and second cylindrical bodies are interlocked, a through hole is left at the upper and lower parts for the fixing strips to pass through.

[0014] Furthermore, after the first and second cylinders are fastened together, mounting holes are formed at both ends, and a number of protrusions are evenly arranged on the inner surface of the mounting holes; the rotating disk includes a third gear, and when the rotating disk is engaged with the mounting holes, the third gear corresponds one-to-one with the protrusions, and the third gear and the protrusions can rotate synchronously through friction.

[0015] Furthermore, it also includes a lid, which is placed on top of the paper storage compartment to seal it.

[0016] Furthermore, the upper surface of the box lid is provided with a storage groove that slopes towards the back.

[0017] Furthermore, a water-blocking strip is provided on the upper edge of the paper dispensing port, and a through groove is provided on the lower surface of the water-blocking strip.

[0018] (III) Beneficial Effects

[0019] The beneficial effects of this invention are:

[0020] The present invention provides a roll paper box, wherein a pair of closing devices are provided on the inner walls of both sides of the paper storage compartment. The pair of closing devices are respectively inserted through the side wall of the paper storage compartment on their respective sides and connected to both ends of the cover plate. Both ends of the hanging shaft are respectively connected to the two closing devices, so that the cover plate and the hanging shaft are linked through the closing devices: when the cover plate is rotated downward to change from the state of covering the paper dispensing opening to the state of exposing the paper dispensing opening, the closing device drives the hanging shaft to rotate to release paper, causing the roll paper to accumulate at the paper dispensing opening; when the closing device drives the hanging shaft to rotate to retract the paper, causing the roll paper to retract into the paper storage compartment, the closing device drives the cover plate to rotate upward to change from the state of exposing the paper dispensing opening to the state of covering the paper dispensing opening.

[0021] The automatically closing cover and the linked retractable paper roll retract into the paper compartment after use, automatically closing the paper dispensing port. Compared to existing technologies, this effectively prevents moisture intrusion, ensuring the paper towels can be stored in a relatively dry environment for a long time, while also avoiding soiling and waste.

[0038] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] like Figure 1-10 As shown, the present invention provides a roll paper box, such as Figure 1 , Figure 2As shown, the device includes a paper storage compartment 1, a cover plate 2, closure devices 3, a hanging shaft 4, and a box cover 5. A paper dispensing opening 11 is located on the lower front of the paper storage compartment 1. The cover plate 2 is positioned on the outside of the paper storage compartment 1 and can rotate between covering and allowing the paper dispensing opening 11 to protrude. The box cover 5 covers the upper end of the paper storage compartment 1, sealing it. A pair of closure devices 3 are provided and installed on the inner walls of both sides of the paper storage compartment 1. The pair of closure devices 3 pass through the side wall of the paper storage compartment 1 on their respective sides and are connected to both ends of the cover plate 2. Both ends of the hanging shaft 4 are connected to the two closure devices 3, allowing the cover plate 2 and the hanging shaft 4 to move together via the closure devices 3.

[0040] When the cover plate 2 is rotated downwards to change from covering the paper take-up opening 11 to exposing the paper take-up opening 11, the cover plate 2 rotates via the closing device 3 and the hanging shaft 4 to release paper, causing the roll of paper to accumulate at the paper take-up opening 11, while the closing device 3 stores force.

[0041] When the closing device 3 drives the hanging shaft 4 to rotate and retract the paper roll into the paper loading compartment 1, the closing device 3 drives the cover plate 2 to rotate upward, changing from the state of exposing the paper picking opening 11 to the state of covering the paper picking opening 11.

[0042] Among them, such as Figure 3 , Figure 4 As shown, the closure 3 includes a base 31, a gear set 32, and a cover 33. The base 31 and the cover 33 are fastened together to form an inner cavity that accommodates the gear set 32.

[0043] Specifically, the cover 33 is provided with locking hooks 331 on both sides, and the base 31 is provided with locking buckles 311 corresponding to the locking hooks 331 on both sides. The cover 33 and the base 31 are fastened together by locking the locking hooks 331 and locking buckles 311.

[0044] The inner walls on both sides of the paper tray 1 are provided with a pair of latches 12 and positioning strips 13. The pair of latches 12 and positioning strips 13 on the same side form the installation position of the closure device 3 on the same side inside the paper tray 1. The base 31 is provided with latches 312 on both sides. The closure device 3 is supported on the positioning strips 13, and the two latches 312 cooperate with the pair of latches 12 to install the closure device 3 in the installation position.

[0045] The gear set 32 ​​includes a drive gear 321, a power spring 322, an escapement mechanism 323, a ratchet 324, a locking lever 325, a transmission gear 326, and an idler gear 327, all mounted on the base 31. The drive gear 321 includes a torsion spring 3211 and a first gear 3212 coaxially fixed. The first gear 3212 has a locking tongue 3213. The torsion spring 3211 is fixed to the base 31. The torsion spring 3211 begins to store force when the first gear 3212 rotates, causing the first gear 3212 to have a tendency to move in the opposite direction. Figure 5As shown, the power-accumulating spring 322 includes a coaxially fixed spring 3221 and a second gear 3222. A lever 3223 is mounted on the second gear 3222. The spring 3221 begins to accumulate power when the second gear 3222 rotates, causing the second gear 3222 to have a tendency to move in the opposite direction. Figure 3 , Figure 4 As shown, the escapement mechanism 323 includes an escape wheel 3231 and an escape fork 3232 that cooperate with each other. The escape fork 3232 cooperates with the lever 3223 through the fork head. A pull wheel 3233 is coaxially arranged on the escape wheel 3231, causing the pull wheel 3233 to rotate at a constant speed. The ratchet 324 simultaneously meshes with the first gear 3212 and the second gear 3222 to drive the rotation between the power gear 321 and the mainspring 322 in one direction. This allows the power gear 321 to drive the mainspring 322 to rotate when it rotates, but the mainspring 322 will not drive the power gear 321 to rotate when it rotates. The locking lever 325 includes a lever 3251 and a spring 3252. The two ends of the spring 3252 are connected to the base 31 and the pressing end of the lever 3251, respectively. The pressing end can be pressed down by the actuating wheel 3233. The other end of the lever 3251 is provided with a hook, which can engage with the locking tongue 3213. The transmission gear 326 meshes with the drive gear 321 through an idler gear 327, ensuring that the transmission gear 326 and the drive gear 321 move in the same direction.

[0046] When gear set 32 ​​is working, firstly, the first gear 3212 of the drive gear 321 rotates until the locking tongue 3213 of the drive gear 321 engages with the hook on the lever 3251 of the locking rod 325. During this process, the torsion spring 3211 of the drive gear 321 continuously stores power. When the first gear 3212 of the drive gear 321 stops rotating, the drive gear 321 is in a stored-power state. Simultaneously, because the drive gear 321 engages with the power-storing spring 322 via ratchet 324 and with the transmission gear 326 via idler gear 327, the rotation of the first gear 3212 of the drive gear 321 triggers two movements, A and B. Movement A: The transmission gear 326 rotates in the same direction as the first gear 3212. Movement B: The second gear 3222 of the power-storing spring 322 rotates to tighten the power-storing spring 3221.

[0047] After the first gear 3212 of the power gear 321 stops rotating, the second gear 3222 of the power-accumulating spring 322 also stops rotating. At this time, the power-accumulating spring 3221 begins to unload. Because the escape fork 3232 of the escape mechanism 323 cooperates with the lever 3223 of the power-accumulating spring 322, the lever 3223 drives the escape wheel 3231 to start moving at a constant speed through the escape fork 3232 until the lever 3233 on the escape mechanism 323 presses down the lower end of the lever 3251 of the locking lever 325.

[0048] When the lower end of lever 3251 of locking rod 325 is pressed down, the hook on lever 3251 of locking rod 325 will disengage from the locking tongue 3213 of power gear 321. At this time, the first gear 3212 of power gear 321, which is in a charged state, will reverse and return to its original position under the action of torsion spring 3211. During the reversal of the first gear 3212, a motion C will be triggered. Motion C is the rotation of transmission gear 326 in the same direction as the first gear 3212 and in the opposite direction to motion A.

[0049] Specifically, such as Figure 1 , Figure 2 As shown, rotating shafts 21 are provided on both sides of the cover plate 2. The gear shaft of the first gear 3212 passes through the cover 33 and the paper tray 1 and is connected to the rotating shafts 21, so that the cover plate 2 and the power gear 321 rotate synchronously. Therefore, the gear set 32 ​​first needs to open the cover plate 2 to provide initial power to the power gear 321. Finally, when the power gear 321 reverses to unload and return to its original position, it will also drive the cover plate 2 to close, thus achieving the purpose of automatic closing of the cover plate 2.

[0050] In addition, such as Figure 1 , Figure 2 , Figure 9 , Figure 10 As shown, a water-blocking strip 14 is provided on the upper edge of the paper dispensing port 11, which can prevent water falling on the paper storage compartment 1 from falling into the paper storage compartment 1 through the paper dispensing port 11. Moreover, a through groove is provided on the lower surface of the water-blocking strip 14, which helps the cover plate 2 to be embedded in the through groove on the lower surface of the water-blocking strip 14 when it is closed, so that the cover plate 2 is closed in place.

[0051] like Figure 3 , Figure 4 As shown, the gear shaft of the transmission gear 326 passes through the base 31 and is connected to a fixed disk 34, with a first magnet 341 embedded in the fixed disk 34. Figure 6 , Figure 7 As shown, a rotating disk 41 is provided at both ends of the hanging shaft 4. The rotating disk 41 is embedded with a second magnet 411. The second magnet 411 at both ends attracts the corresponding first magnet 341, causing the hanging shaft 4 and the transmission gear 326 to rotate synchronously. The cover plate 2 rotates synchronously with the power gear 321. Therefore, the cover plate 2 and the hanging shaft 4 are linked.

[0052] like Figure 6 , Figure 7 , Figure 8 , Figure 10As shown, the hanging shaft 4 includes two interlocking first cylindrical bodies 42 and second cylindrical bodies 43. A mounting platform 44 is horizontally arranged at the central axis inside the first cylindrical body 42. Fixing strips 46 are mounted on both the upper and lower parts of the mounting platform 44 via springs 45. After the first cylindrical body 42 and second cylindrical body 43 are interlocked, a through hole is left at both the upper and lower parts for the fixing strips 46 to pass through. When the hanging shaft 5 is inserted into the cylinder in the middle of the paper roll, the paper roll fixing strips 46 are tightly connected to the paper roll cylinder by the elastic force of the springs 45 below them.

[0053] After the first cylinder body 42 and the second cylinder body 43 are fastened together, mounting holes are formed at both ends. The inner surface of the mounting holes is evenly provided with a number of protrusions 47. The rotating disk 41 includes a third gear 412. When the rotating disk 41 is engaged with the mounting hole, the third gear 412 corresponds one-to-one with the protrusions 47. The third gear 412 and the protrusions 47 can rotate synchronously through friction.

[0054] Since the third gear 412 and the protrusion 47 rotate synchronously through friction rather than through meshing, when both ends of the hanging shaft 4 are jammed, the third gear 412 cannot rotate, preventing normal paper feeding. In this case, the paper can be manually rotated by inserting a force greater than the friction force into the paper feeding port 11, causing the hanging shaft 4 to rotate independently. Therefore, the hanging shaft 4 can be rotated either by the closing device 3 or by manual intervention.

[0055] When in use, the hanging shaft 4 with the roll of paper loaded is placed into the paper loading compartment 1. The rotating disks 41 at both ends of the hanging shaft 4 are magnetically connected to the fixed disks 34 on the closure device 3. This connection method does not require precise alignment and is easy to disassemble and assemble, making it easy to meet the needs of changing the roll of paper.

[0056] The upper surface of the lid 5 is provided with a storage groove 51 that is inclined to the back, which prevents the lid 5 from being closed upside down, and also prevents items placed in the lid 5 from sliding to the front, as well as the drawback of water accumulation in the storage groove 51.

[0057] Working principle:

[0058] The downward opening of the cover plate 2 provides power to the closing device 3. When movement A is triggered, that is, when the transmission gear 326 and the first gear 3212 rotate in the same direction, the transmission gear 326 drives the hanging shaft 4 to rotate and release the paper, causing the roll of paper to accumulate at the paper dispensing port 11, and paper dispensing begins. When the closing device 3 continues to work and triggers movement C, that is, when the transmission gear 326 and the first gear 3212 rotate simultaneously in the opposite direction to movement A, the transmission gear 326 drives the hanging shaft 4 to rotate and retract the paper, causing the exposed roll of paper to retract into the paper loading compartment 1. At the same time, the rotation of the first gear 3212 will cause the cover plate 2 to rotate upward and automatically close, achieving the effect of automatically closing the paper dispensing port 11 while retracting the roll of paper outside the paper loading compartment 1.
