Abstract
Description
Technical Field
[0001] The present application relates to the technical field of storage and access of household paper, and in particular to a storage and access box for household paper. Background Art
[0002] Household paper refers to various types of sanitary wipes used for personal care at home and on the go, and is a familiar daily necessity. Among household paper products, a common packaging format is roll paper, such as toilet paper rolls, treasure toilet paper, and roll-type wipes (kitchen paper, roll-type hand towels).
[0003] Common roll paper dispensers on the market include household toilet paper dispensers and non-household toilet paper dispensers or roll-type wipe dispensers. When paper is pulled from a roll, the paper core rotates relative to the toilet paper rod. If excessive force is applied, the roll will rotate due to inertia, causing more paper to fall out, resulting in unnecessary waste.
[0004] Existing roll-type paper dispensers require two hands to separate the paper from the roll, requiring one hand to grasp the top section while the other to tear the paper. This creates inconvenience when removing paper, especially when both hands are occupied with other objects or are otherwise inconvenient. Retrieving the desired length of paper towel becomes a challenge. Furthermore, the need to manually grasp the unused top section creates psychological barriers and embarrassment for subsequent users who prioritize cleanliness. This embarrassment and discomfort is particularly pronounced in public places such as airports and hotels. Summary of the Invention
[0005] The present application provides a household paper storage and access box to solve the problems of existing household paper storage and access boxes that inevitably cause unnecessary paper waste, are inconvenient to extract paper, and cannot ensure the hygiene and cleanliness of paper.
[0006] In order to solve the above technical problems, the present application provides a storage and access box for daily use paper, wherein the storage and access box for daily use paper includes: a box body shell, the box body shell includes a base and a box cover buckled on the base, wherein a paper outlet is opened on a first side portion of the base; a first rotating shaft, one end of the first rotating shaft is connected to the second side portion of the base, and an elastic member is connected between the first rotating shaft and the second side portion of the base; a second rotating shaft, the second rotating shaft is sleeved on the first rotating shaft and is used to sleeve a roll of daily use paper; a ratchet assembly is rotatably connected to the first rotating shaft and the second rotating shaft; wherein, when the roll of daily use paper drives the second shaft to rotate along the first direction, the second shaft drives the ratchet assembly to rotate, and the ratchet assembly drives the first shaft to rotate synchronously along the first direction, and causes the first shaft to compress the elastic member.
[0007] Among them, the ratchet assembly includes a ratchet disc and a pawl. The ratchet disc is fixedly mounted on the first rotating shaft. One end of the pawl is connected to the second rotating shaft, and the other end of the pawl is in contact with the ratchet disc. When the second rotating shaft rotates along the first direction, it drives the pawl to rotate, and the pawl drives the ratchet disc to rotate.
[0008] The ratchet disc is a gear-shaped structure, one end of the pawl is connected to the second rotating shaft, and the other end of the pawl abuts against one of the gears on the ratchet disc.
[0009] The elastic member is a planar spiral spring, the inner ring of the planar spiral spring is connected to one end of the first rotating shaft close to the second side of the base, and the outer ring of the planar spiral spring is fixedly connected to the second side of the base.
[0010] Wherein, an elastic convex strip is provided on the outer side of the second rotating shaft, and the elastic convex strip is compressed by the roll-type household paper when the roll-type household paper is sleeved on the second rotating shaft.
[0011] The household paper storage and access box further comprises a locking assembly, which comprises a first locking member arranged on the box cover and a second locking member correspondingly arranged on the base, wherein the first locking member is used to cooperate with the second locking member to lock the box cover and the base.
[0012] The locking assembly further includes an unlocking member, which is used to drive the first locking member to move relative to the second locking member to lock the box cover and the base, or to release the lock between the box cover and the base.
[0013] The first locking member is arranged on the first side portion of the box cover, the second locking member is arranged on the third side portion of the base, and the second side portion of the box cover is hinged to the fourth side portion of the base.
[0014] The first locking member includes a rotating tongue, and the second locking member includes a locking hole. The rotating tongue can be extended into the locking hole and rotated to a position perpendicular to the locking hole, thereby locking the box cover and the base; or the rotating tongue can be rotated from perpendicular to the locking hole to parallel to the locking hole to pull out of the locking hole, thereby releasing the lock between the box cover and the base.
[0015] The first locking member includes an elastic card block, and the second locking member includes a card slot. The elastic card block can be inserted into or withdrawn from the card slot to lock or release the lock between the box cover and the base.
[0016] The beneficial effect of the present application is that, different from the prior art, the household paper storage and access box provided by the present application includes: a box body shell, a first rotating shaft, a second rotating shaft, an elastic member connected between the first rotating shaft and the second side portion of the base, and a ratchet assembly, wherein, when the roll-type household paper is extracted from the paper outlet of the box body shell and the second shaft body is driven to rotate along the first direction, the second shaft body drives the ratchet assembly to rotate, and the ratchet assembly can drive the first shaft body to rotate synchronously along the first direction and cause the first shaft body to compress the elastic member, thereby making the method of extracting household paper more convenient, and roughly equal portions of roll-type household paper can be extracted each time to avoid paper waste and ensure the hygienic cleanliness of the roll-type household paper.

[0028] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0029] See also Figure 1 and Figure 2 ,in, Figure 1 This is a structural diagram of an embodiment of the household paper storage and access box of the present application. Figure 2 yes Figure 1 In this embodiment, the household paper storage and access box includes a box body shell 10, a first rotating shaft 21, a second rotating shaft 22 and a ratchet assembly 40.
[0030] The box body shell 10 includes a base 11 and a box cover 12 buckled on the base 11. The box cover 12 can be opened or buckled from the base 11 to facilitate the storage and access of the roll-type household paper 100, and a paper outlet 110 is also opened on the first side of the base 11 so that the household paper can be extracted from the paper outlet 110.
[0031] One end of the first rotating shaft 21 is rotatably connected to the second side of the base 11, and an elastic member 30 is connected between the first rotating shaft 21 and the second side of the base 11. A second rotating shaft 22 is sleeved on the outer side of the first rotating shaft 21, and a ratchet assembly 40 is further rotatably connected between the first rotating shaft 21 and the second rotating shaft 22. The first side and the second side of the base 11 can be two mutually perpendicular sides, and the second rotating shaft 22 is used to sleeve the roll-type household paper 100 so that portions of the household paper can be withdrawn in sequence.
[0032] When the user extracts the roll of household paper 100 and drives the second rotating shaft 22 to rotate in the first direction, the second rotating shaft 22 can drive the ratchet assembly 40 to rotate, so that the ratchet assembly 40 drives the first rotating shaft 21 to rotate synchronously in the first direction, and the first rotating shaft 21 can further compress the elastic member 30, so that when a set portion, such as a set number of sections of the roll of household paper 100, is extracted from the paper outlet 110, the elastic force generated by the compression of the elastic member 30 can be reversely applied to the second rotating shaft 22 through the ratchet assembly 40, and further applied to the roll of household paper 100. When the force transmitted by the elastic force is greater than the paper strength of the roll of household paper 100, the household paper extracted this time can be cut off. Since the paper strength of each part of the roll of household paper 100 is roughly equal, the critical point at which it and the elastic force of the elastic member 30 are balanced with each other remains roughly unchanged. Therefore, equal portions of the roll of household paper can be extracted each time.
[0033] Among them, when the first rotating shaft 21 rotates and resets in a second direction opposite to the first direction under the action of the rebound force of the elastic member 30, the second rotating shaft 22 can stop rotating under the resistance of the ratchet assembly 40, so as to ensure that the new paper head left after each extraction of the daily paper can be maintained in the same position. Among them, the set part of the daily paper that can be extracted each time is determined by the rebound force of the elastic member 30 and the strength of the daily paper, so as to effectively avoid unnecessary waste of daily paper.
[0034] Optionally, the first direction may be clockwise, and the second direction may be counterclockwise. In other embodiments, the first direction may be counterclockwise, and the second direction may be clockwise. This application does not limit this.
[0035] Optionally, the roll-type household paper 100 can be specifically installed on the second rotating shaft 22 through the core tube 101, and the core tube 101 can be tightly fitted with the outer side of the second rotating shaft 22, so that when the roll-type household paper 100 is stored, the paper head 102 of the roll-type household paper 100 can hang vertically and be exposed outside the box body shell 10 from the paper outlet 110 so that the box cover 12 can be closed.
[0036] Specifically, when paper needs to be pulled, the paper head 102 can be pulled downward, causing the roll 100 to rotate along the second rotating shaft 22 in the first direction to dispense a portion of paper. The ratchet assembly 40 then drives the first rotating shaft 21 to rotate synchronously in the first direction, and the elastic member 30 is compressed inwardly in the first direction. It can be understood that when the elastic member 30 can no longer be compressed in the first direction due to the paper pulling force, the roll 100 will stop rotating in the first direction, and the paper roll 100 will stop dispensing paper. At this time, the paper dispensed this time can be pulled apart to form a new paper head at the break of the paper, and the elastic member 30 will rebound in a second direction opposite to the first direction, so that the first rotating shaft 21 is driven by the elastic member 30 to rotate and reset in the second direction relative to the second rotating shaft 22. However, the second rotating shaft 22 can remain stationary and not rotate in the second direction under the resistance of the ratchet assembly 40, so that the new paper head still stays at the position where the original paper head 102 is located, so as to facilitate the next pulling.
[0037] It can be understood that the strength of the paper distributed by the roll-type household paper 100 is greater than the contraction force of the elastic member 30 before the maximum elastic force is achieved in a process of pulling the paper and the paper strength is balanced. In an optional embodiment, break lines are provided at intervals on the distributed paper for easy breaking, and the strength of the paper distributed by the roll-type household paper 100 at the break line is greater than the contraction force of the elastic member 30 before the maximum elastic force is achieved in a process of pulling the paper and the paper strength is balanced, and is less than the paper strength, so that the corresponding household paper can be cut off at the break line.
[0038] Optionally, a paper cutter is further provided at the edge of the paper outlet 110 on the first side of the base 11 to assist in breaking the dispensed paper. The dispensed paper is placed against the paper cutter to more effectively break the paper. The paper cutter is integral with the base 11 and can be serrated in shape.
[0039] Please refer to Figure 3 and Figure 4 ,in, Figure 3 yes Figure 1 BB cross-sectional view of the household paper storage box. Figure 4 yes Figure 1CC cross-sectional view of the household paper storage box.
[0040] In this embodiment, the ratchet assembly 40 includes a ratchet disc 41 and a pawl 42. The ratchet disc 41 is sleeved on the first rotating shaft 21, and one end of the pawl 42 is connected to the second rotating shaft 22, and the other end of the pawl 42 is in contact with the ratchet disc 41. When the second rotating shaft 22 rotates in the first direction, it can drive the pawl 42 to rotate, and drive the ratchet disc 41 to rotate through the pawl 42, and the ratchet disc 41 can only rotate unidirectionally in the first direction under the drive of the pawl 42.
[0041] Among them, the ratchet disk 41 is a gear-like structure, and the tip end of the gear of the ratchet disk 41 is deflected toward the first direction. The pawl 42 is an integrated structure composed of two sections of cylinders with different extension directions, or an integrated arc structure, and one end of the pawl 42 is connected to the second rotating shaft 22, and the other end of the pawl 42 is embedded in one of the gears of the ratchet disk 41.
[0042] Optionally, the elastic member 30 is a planar spiral spring, and the inner ring of the planar spiral spring is connected to one end of the first rotating shaft 21 close to the second side of the base 11, and the end of the outer ring of the planar spiral spring is fixedly connected to the second side of the base 11.
[0043] Furthermore, the friction force between the ratchet disc 41 and the first rotating shaft 21 is smaller than the resistance generated by the ratchet assembly 40 on the second rotating shaft 21, and the friction force is greater than the rotational force of the second rotating shaft 22 driving the ratchet assembly 40 to move in the first direction, so that the first rotating shaft 21 can be driven to rotate in the first direction by the ratchet disc 41, while the pawl 42 and the ratchet disc 41 cannot be driven by the first rotating shaft 21 to rotate in the second direction.
[0044] Furthermore, at least one elastic ridge is provided on the outer side of the second rotating shaft 22, and the elastic ridge extends along the axial direction of the second rotating shaft 22, so that when the roll-type household paper 100 is sleeved on the second rotating shaft 22, the elastic ridge can be compressed to generate an elastic force and act on the inner wall of the core tube 101, thereby ensuring that the roll-type household paper 100 and the second rotating shaft 22 can be tightly fitted, so that the roll-type household paper 100 can rotate synchronously with the second rotating shaft 22.
[0045] Optionally, the box body shell 10 also includes a locking assembly, which specifically includes a first locking member arranged on the box cover 12 and a second locking member correspondingly arranged on the base 11, and the first locking member can cooperate with the second locking member to lock the box cover 12 and the base 11.
[0046] Specifically, after the roll-type household paper 100 is installed and the box cover 12 is closed, the box cover 12 can be locked with the base 11 to effectively prevent the roll-type household paper 100 from being stolen, thereby causing an embarrassing situation where there is no paper available.
[0047] Furthermore, the locking assembly also includes an unlocking piece, and the unlocking piece is separately arranged from the box body shell 10 so that it can be connected to the box cover 12 from the outside of the box body shell 10, and the first locking piece can move relative to the second locking piece to release the lock between the box cover 12 and the base 11 or lock the box cover 12 and the base 11.
[0048] Specifically, the first locking member is arranged on the first side of the box cover 12, and the second locking member is arranged on the third side of the base 11, and the second side of the box cover 12 is hinged on the fourth side of the base 11 so that the box cover 12 can be locked to the base 11.
[0049] Please continue reading Figure 5 , Figure 5 yes Figure 1 A schematic top view of the household paper storage and access box. In this embodiment, the entire roll of household paper 100 is enclosed within the box housing 10. The first locking member is located at the top of the box lid 12, and correspondingly, the second locking member is located at the top of the base 11. The bottom of the box lid 12 is hinged to the bottom of the base 11, and the top and both sides of the box lid 12 can be snapped onto the base 11.
[0050] Furthermore, the first locking component includes an elastic card block 51, and the second locking component includes a limiting card slot formed by a card strip 52, so that the elastic card block 51 can lock the box cover 12 and the base 11 by being snapped into the card slot, or the elastic card block 51 can be withdrawn from the card slot to release the lock between the box cover 12 and the base 11.
[0051] Please refer to Figure 6 , Figure 6 yes Figure 5 A cross-sectional view (AA) of the household paper storage and access box. In this embodiment, when the lid 12 is snapped onto the base 11, the elastic block 51 snaps into the upper portion of the slot 53, locking the lid 12 to the base 11. Furthermore, two unlocking holes 54 are defined at the top of the lid 12. An unlocking member can be inserted into at least one of the unlocking holes 54, pushing the elastic block 51 downward, causing it to move downward to the lower portion of the slot 53 and exit from the slot 53, releasing the lock between the lid 12 and the base 11.
[0052] The upper width of the slot 53 is smaller than the width of the elastic block 51 , while the lower width of the slot 53 is larger than the width of the elastic block 51 . The elastic block 51 can be compressed to make its width smaller than or equal to the upper width of the slot 53 .
[0053] See also Figure 7-Figure 8 ,in, Figure 7 This is a structural diagram of another embodiment of the household paper storage and access box of the present application. Figure 8 yes Figure 1 Right view of the household paper storage box.
[0054] In this embodiment, the first locking member is arranged on the first side of the box cover 12, the second locking member is arranged on the third side of the base 11, and the second side of the box cover 12 is hinged on the fourth side of the base 11, and the box cover 12 can be fastened to the base 11 and can be rotated along one end of the fourth side of the base 11 to open or fasten the box cover 12, thereby placing or removing the roll-type household paper 100, wherein the third side of the base 11 is arranged opposite to its fourth side and is perpendicular to the first side of the base 11 and the second side of the base 12, and the first side of the box cover 12 is arranged opposite to its second side. In other embodiments, the first locking member can also be arranged on the second side of the box cover 12, and the second locking member can be arranged on the fourth side of the base 11, and the first side of the box cover 12 is hinged on the third side of the base 11. This is not limited in this application.
[0055] Optionally, the upper part of the roll-type household paper 100 is enclosed in the box shell 10. In order to facilitate observation to understand the usage of the roll-type household paper 100, the height of the box shell 10 can be set to be no less than two-thirds of the roll diameter of the common roll-type household paper 100.
[0056] The first locking member includes a rotating tongue 55 , and the second locking member includes a locking hole 56 . The rotating tongue 55 can extend into the locking hole 56 and rotate to a position perpendicular to the locking hole 56 , thereby locking the box cover 12 and the base 11 .
[0057] Alternatively, when the tongue 55 is rotated to a direction parallel to the locking hole 56 and the box cover 12 is closed, the tongue 55 can be inserted into the locking hole 56 and rotated 90° in a certain direction so that it is perpendicular to the locking hole 56. At this time, the tongue 55 is firmly fixed in the locking hole 56 and locks the box cover 12 to the base 11. When it is necessary to release the lock between the box cover 12 and the base 11, the tongue 55 can be rotated 90° in the opposite direction so that it is parallel to the locking hole 56, thereby allowing it to be withdrawn from the locking hole 56.
[0058] Furthermore, an unlocking hole 57 is provided on the outside of the right side of the box cover 12 , and an unlocking piece can be inserted into the unlocking hole 57 to drive the rotating tongue 55 to rotate.
[0059] For ease of explanation, the following is a specific method for storing and accessing roll-type household paper using the above-mentioned household paper storage and access box, which specifically includes the following steps:
[0060] S11: Open the box cover 12 to install the roll-type household paper 100 onto the rotating shaft 20 through the core tube 101;
[0061] S12: Allow the paper head 102 of the roll-type household paper 100 to hang vertically so as to be exposed outside the box body 10 from the paper outlet 110, and close the box cover 12;
[0062] S13: Pull the paper head 102 downward, and rotate the roll of household paper 100 along the second rotating shaft 22 along the first direction to dispense a set number of papers;
[0063] S14: breaking the dispensed paper and stopping the second rotating shaft 22 to form a new paper head at the break of the paper;
[0064] S15: The first rotating shaft 21 rotates relative to the second rotating shaft 22 in a second direction opposite to the first direction to reset.
[0065] Between S12 and S13 , the process further includes rotating the first locking member relative to the second locking member to lock the box cover 12 and the base 11 .
[0066] In S13, under the action of the downward pulling force, when the elastic member 30 can no longer be compressed in the first direction, the roll-type household paper 100 will stop rotating in the first direction and the roll-type household paper 100 will stop dispensing paper. Only then can S14 be performed, wherein the elastic member 30 is preferably a flat spiral spring, so that the roll-type household paper 100 rotates in the first direction along with the second rotating shaft 22 and is wound inwardly.
[0067] In S14 , when the new paper head stays at the position of the original paper head 102 , it is convenient for the next paper pulling.
[0068] And only after S15 is completed can the next pulling action be performed.
[0069] The beneficial effect of the present application is that, different from the prior art, the household paper storage and access box provided by the present application includes: a box body shell, a first rotating shaft, a second rotating shaft, an elastic member connected between the first rotating shaft and the second side portion of the base, and a ratchet assembly, wherein, when the roll-type household paper is extracted from the paper outlet of the box body shell and the second shaft body is driven to rotate along the first direction, the second shaft body drives the ratchet assembly to rotate, and the ratchet assembly can drive the first shaft body to rotate synchronously along the first direction and cause the first shaft body to compress the elastic member, thereby making the method of extracting household paper more convenient, and roughly equal portions of roll-type household paper can be extracted each time to avoid paper waste and ensure the hygienic cleanliness of the roll-type household paper.
