Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, and in particular to a paper dispensing component and a tissue box. Background Technology

[0002] Toilet paper is usually sold in rolls. To prevent the roll from sticking or breaking apart when wet, it is typically placed inside a tissue box. Currently, there are many types of toilet paper dispensers on the market, but most only serve a protective function. The process of taking out the paper still involves pulling out the roll with one hand and then using the other hand to hold the roll steady and pull it apart. After the roll is cut or torn, the end of the paper is often located at the paper outlet or protrudes slightly beyond it. This makes it inconvenient for users to pull out the end of the paper the next time they need to use it, and sometimes they even have to reach into the paper outlet to find the end of the paper, making it inconvenient to use. Utility Model Content

[0003] The purpose of this utility model is to provide a paper output component and a tissue box, which has a simple structure and is easy to operate. It can automatically cut the paper roll by dragging it with one hand and actively output part of the paper roll after it is cut.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] In a first aspect, a paper output assembly is provided, including a mounting base, a drive roller assembly, and a paper cutting and feeding mechanism. The drive roller assembly includes a first drive roller and a second drive roller rotatably connected to the mounting base. The outer peripheral walls of the first drive roller and the second drive roller are always in contact, and a roll of paper is clamped between the outer peripheral walls of the first drive roller and the second drive roller. The paper cutting and feeding mechanism is disposed on the mounting base and includes a switching component, a paper cutting component, and a paper feeding component. The switching component is connected to the first drive roller and can drive the first drive roller to reciprocate in a first position and a second position. When the first drive roller is in the first position, the first drive roller is drivenly connected to the paper cutting component, and the paper cutting component can stop the first drive roller from rotating, thereby allowing the roll of paper to be torn under drag. When the first drive roller is in the second position, the first drive roller is drivenly connected to the paper feeding component, and the paper feeding component can actively drive the first drive roller to rotate to output a portion of the roll of paper.

[0006] As a preferred embodiment of the paper output assembly, the mounting base includes a first mounting plate and a second mounting plate, the first mounting plate and the second mounting plate being spaced apart along a first direction to form a receiving space, the transmission roller group being disposed within the receiving space, the lengths of the first transmission roller and the second transmission roller both extending along the first direction, and the paper cutting and feeding mechanism being disposed on the side of the first mounting plate away from the transmission roller group along the first direction.

[0007] As a preferred embodiment of the paper output assembly, the first mounting plate and the second mounting plate are respectively provided with guide grooves. The length of the guide grooves extends along the second direction, and the guide grooves have a first position and a second position arranged along the second direction. The receiving space has a paper inlet and a paper outlet arranged opposite to each other along the paper output direction. The first position is arranged adjacent to the paper outlet. The two ends of the first drive roller are slidably connected to the two guide grooves respectively. The switching component includes a first elastic element. The first elastic element is provided on both the first mounting plate and the second mounting plate. The first elastic element is connected to the first drive roller. The first elastic element always has the tendency to drive the first drive roller to move toward the second position. Under the drag of the paper roll, the first drive roller can overcome the elastic force of the first elastic element and move toward the first position. The first direction and the second direction are arranged at an angle.

[0008] As a preferred embodiment of the paper output assembly, a first gear is provided at one end of the first drive roller adjacent to the paper cutting and feeding mechanism. The paper cutting assembly includes a first rotating shaft, a second gear, and a gear set. The first rotating shaft is disposed on the first mounting plate, and the length of the first rotating shaft extends along the first direction. The second gear is disposed on the first rotating shaft. The first gear can rotate the second gear through the gear set. A stop portion is also provided on the first mounting plate. The stop portion can stop the second gear from rotating, thereby stopping the first gear from rotating.

[0009] As a preferred embodiment of the paper feeding assembly, the paper feeding assembly includes a third mounting plate, a first rack, a second rack, and a second elastic member. The third mounting plate is slidably disposed on the first mounting plate along a third direction. The first rack and the second rack are spaced apart on the third mounting plate along the first direction, and the lengths of the first rack and the second rack extend along the third direction. The second rack meshes with the second gear. When the first drive roller is in the first position, the first drive roller drives the first gear to rotate, so that the rotation of the second gear can drive the second rack to move along the third direction until it stops at the stop portion. When the first drive roller is in the second position, the first gear meshes with the first rack. The third mounting plate is connected to the mounting base through the second elastic member. The second elastic member always has a tendency to drive the mounting plate away from the stop portion. The third direction is perpendicular to the first direction and forms an angle with the second direction.

[0010] As a preferred embodiment of the paper output assembly, the paper output assembly further includes a cover, and the first mounting plate has an installation groove on one side along the first direction. The cover is used to seal the opening of the installation groove. The paper cutting assembly and the paper feeding assembly are both disposed in the installation groove. The third mounting plate is slidably disposed between the cover and the bottom of the installation groove. The second rack can move along the third direction and stop against the groove wall of the installation groove.

[0011] As a preferred embodiment of the paper output assembly, the gear set includes a third gear, the first rotating shaft is rotatably mounted on the first mounting plate, and the third gear and the second gear are spaced apart along the first direction outside the first rotating shaft, the first gear being capable of meshing with the third gear; or...

[0012] The gear set includes a third gear, a second rotating shaft, and a fourth gear. The second gear, the third gear, and the fourth gear are all reduction gears. The second rotating shaft and the first rotating shaft are fixedly mounted on the first mounting plate at a distance. The length of the second rotating shaft extends along the first direction. The second gear and the third gear are rotatably connected to the outside of the first rotating shaft, and the second gear and the third gear are spaced apart along the first direction. The fourth gear is rotatably connected to the second rotating shaft. The first gear can mesh with the third gear, the third gear can mesh with the fourth gear, and the fourth gear can mesh with the second gear.

[0013] In a second aspect, a tissue box is provided, including a box body and the aforementioned paper dispensing assembly. The tissue box has a receiving cavity for accommodating a roll of paper, and the tissue box is provided with an outlet communicating with the receiving cavity. The paper dispensing assembly is disposed in the receiving cavity and is disposed adjacent to the outlet. The roll of paper from the roll of paper can be pulled out from the outlet through the paper dispensing assembly.

[0014] The beneficial effects of this utility model are as follows: By setting up a paper-cutting and feeding mechanism, when the roll of paper is dragged, it pulls the first transmission roller to the first position and connects it with the paper-cutting component. This allows the first transmission roller to rotate a specified size as the roll of paper is dragged, and then the rotation is restricted by the paper-cutting component, thereby increasing the frictional resistance between the roll of paper and the first transmission roller. This allows the roll of paper to be torn as it continues to be dragged. Users only need to drag the roll of paper with one hand to pull and break it, making the operation convenient and quick, and effectively ensuring the cleanliness and smoothness of each paper retrieval. After the roll of paper is torn, the first transmission roller is pulled to the second position by the switching component and connects with the paper feeding component. This allows the paper feeding component to actively drive the first transmission roller to rotate and output part of the roll of paper, ensuring that the paper end of the roll is kept in a suitable position and avoiding the situation where the paper end is difficult to pull out, thus ensuring the convenience of each paper retrieval.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0025] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0028] like Figures 1 to 6 As shown, the paper output assembly of this utility model embodiment includes a mounting base 1, a transmission roller group 2, and a paper cutting and feeding mechanism 3. The transmission roller group 2 includes a first transmission roller 21 and a second transmission roller 22 rotatably connected to the mounting base 1. The outer peripheral walls of the first transmission roller 21 and the second transmission roller 22 are always in contact, and the rolled paper is clamped between the outer peripheral walls of the first transmission roller 21 and the second transmission roller 22. The paper cutting and feeding mechanism 3 is mounted on the mounting base 1 and includes a switching element 31, a paper cutting assembly 32, and a paper feeding assembly 33. The switching element 31 and the paper cutting assembly 33 are connected to the mounting base 1. The first drive roller 21 is connected and can drive the first drive roller 21 to reciprocate in the first position 141 and the second position 142. When the first drive roller 21 is in the first position 141, the first drive roller 21 is connected to the paper cutting assembly 32. The paper cutting assembly 32 can stop the first drive roller 21 from rotating, so that the roll of paper can be torn apart under drag. When the first drive roller 21 is in the second position 142, the first drive roller 21 is connected to the paper feeding assembly 33. The paper feeding assembly 33 can actively drive the first drive roller 21 to rotate to output part of the roll of paper.

[0029] Understandably, by setting up the paper-cutting and feeding mechanism 3, when the roll of paper is dragged, it pulls the first transmission roller 21 to the first position 141 and is connected to the paper-cutting assembly 32. This allows the first transmission roller 21 to rotate a specified size as the roll of paper is dragged, and then the rotation is restricted by the paper-cutting assembly 32. This increases the frictional resistance between the roll of paper and the first transmission roller 21, so that the roll of paper can be torn as it continues to be dragged. Users only need to drag the roll of paper with one hand to pull and break it, making the operation convenient and quick, and effectively ensuring the cleanliness and smoothness of each paper retrieval. After the roll of paper is torn, the first transmission roller 21 is pulled to the second position 142 under the action of the switching component 31 and is connected to the paper feeding assembly 33. This allows the paper feeding assembly 33 to actively drive the first transmission roller 21 to rotate to output part of the roll of paper, ensuring that the paper head is kept in a suitable position and avoiding the situation where the paper head is difficult to pull out, thus ensuring the convenience of each paper retrieval. In addition, since the paper roll breaking process is automatically controlled by the paper breaking component 32, it reduces the interference of traditional manual operation that requires the other hand to hold the paper roll, avoids hygiene problems that may be caused by improper operation or hand contact, and further improves the safety and hygiene of paper roll use.

[0030] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, the mounting base 1 includes a first mounting plate 11 and a second mounting plate 12. The first mounting plate 11 and the second mounting plate 12 are spaced apart along a first direction to form a receiving space 13 (the first direction is the Y direction shown in the figure). The transmission roller assembly 2 is disposed within the receiving space 13. The lengths of the first transmission roller 21 and the second transmission roller 22 both extend along the first direction. The paper-cutting and feeding mechanism 3 is disposed on the side of the first mounting plate 11 away from the transmission roller assembly 2 along the first direction. By placing the paper-cutting and feeding mechanism 3 on the side of the first mounting plate 11 away from the transmission roller assembly 2, it helps to reduce mutual interference between the paper-cutting and feeding mechanism 3 and the transmission roller assembly 2, thereby improving operational stability.

[0031] In this embodiment, the mounting base 1 is a fixed frame, and the first mounting plate 11 and the second mounting plate 12 are two side plates of the fixed frame spaced apart along the first direction. The fixed frame structure is stable and easy to install. Of course, in some embodiments, the mounting base 1 can also achieve the installation of the transmission roller group 2 and the paper feeding mechanism 3 by consisting only of the first mounting plate 11 and the second mounting plate 12 spaced apart along the first direction.

[0032] Furthermore, guide grooves 14 are correspondingly provided on the first mounting plate 11 and the second mounting plate 12. The length of the guide grooves 14 extends along the second direction (the second direction is the W direction shown in the figure), and the guide grooves 14 have a first position 141 and a second position 142 arranged along the second direction. The accommodating space 13 has a paper inlet 131 and a paper outlet 132 arranged opposite to each other along the paper output direction (the paper output direction is the Z direction shown in the figure, usually a vertical direction). The first position 141 is arranged adjacent to the paper outlet 132. The two ends of the first drive roller 21 are slidably connected to the two guide grooves 14 respectively. The switching component 31 includes a first elastic element. The first mounting plate 11 and the second mounting plate 12 are both provided with the first elastic element. The first elastic element is connected to the first drive roller 21. The first elastic element always has the tendency to drive the first drive roller 21 to move toward the second position 142. Under the drag of the paper roll, the first drive roller 21 can overcome the elastic force of the first elastic element and move toward the first position 141. The first direction and the second direction are arranged at an angle.

[0033] It is understandable that the second direction, i.e., the tangential direction of the second drive roller 22, ensures that the first drive roller 21 remains in contact with the second drive roller 22 regardless of whether it is in the first position 141 or the second position 142. This allows the rotation of the second drive roller 22 to drive the paper roll. Furthermore, the distance from the first position 141 to the second drive roller 22 along the third direction is greater than the distance from the second position 142 to the second drive roller 22. The guide groove 14 ensures that the first drive roller 21 slides along a fixed trajectory during operation, preventing deviation or unstable operation and improving equipment stability and transmission accuracy. The first elastic element overcomes its elastic force to move towards the first position 141 when dragged by the paper roll, and moves towards the second position 142 under elastic force when the paper roll breaks. This simple structure and convenient operation, along with the reduced energy consumption of the drive structure, make the switching of the first drive roller 21 position highly convenient. Furthermore, the first drive roller 21 is provided with first elastic elements at both ends adjacent to the first mounting plate 11 and the second mounting plate 12, which can effectively improve the balance and stability of the movement of the two ends of the first drive roller 21.

[0034] It should be noted that a first fixing part 16 is also provided on the first mounting plate 11 and the second mounting plate 12. The first fixing part 16 is spaced apart on the side of the second transmission roller 22 away from the first transmission roller 21. The first elastic element connects the first fixing part 16 and the first transmission roller 21, thereby enabling the second transmission roller 22 to move toward the second position 142.

[0035] Specifically, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a first gear 34 is provided at one end of the first transmission roller 21 near the paper cutting and feeding mechanism 3. The paper cutting assembly 32 includes a first rotating shaft 321, a second gear 322 and a gear set 323. The first rotating shaft 321 is provided on the first mounting plate 11 and the length of the first rotating shaft 321 extends along the first direction. The second gear 322 is provided on the first rotating shaft 321. The first gear 34 can make the second gear 322 rotate through the gear set 323. A stop part is also provided on the first mounting plate 11. The stop part can stop the second gear 322 from rotating, so that the first gear 34 can stop rotating. Under the drag of the paper roll, the first transmission roller 21 moves to the first position 141 in the second direction, so that the first gear 34 can mesh with the second gear 322 through the gear set 323 to achieve transmission. Under the continuous drag of the paper roll, the second gear 322 continues to rotate until it is stopped by the stop part, so that the first gear 34 and the first transmission roller 21 can no longer rotate. The first transmission roller 21 and the second transmission roller 22 clamp the paper roll. At this time, if the paper roll is dragged again, the paper roll will break along the dotted line segment at the factory, thereby achieving the tearing of the paper roll.

[0036] Furthermore, the paper feeding assembly 33 includes a third mounting plate 331, a first rack 332, a second rack 333, and a second elastic member 334. The third mounting plate 331 is slidably disposed on the first mounting plate 11 along a third direction (the third direction is the X direction shown in the figure). The first rack 332 and the second rack 333 are spaced apart on the third mounting plate 331 along a first direction, and the lengths of the first rack 332 and the second rack 333 extend along the third direction. The second rack 333 meshes with the second gear 322, and the first transmission roller 21 is located in the first position. When the first transmission roller 21 is in position 141, the first transmission roller 21 drives the first gear 34 to rotate, so that the second gear 322 rotates and drives the second rack 333 to move along the third direction until it stops at the stop. When the first transmission roller 21 is in the second position 142, the first gear 34 meshes with the first rack 332. The third mounting plate 331 is connected to the mounting base 1 through the second elastic member 334. The second elastic member 334 always has the tendency to drive the mounting plate away from the stop. The third direction is set perpendicular to the first direction and forms an angle with the second direction.

[0037] In other words, the second gear 322 rotates to drive the second rack 333 to move, thereby stopping the second gear 322 from rotating by stopping the second rack 333 at the stopping part. That is, the stopping part is provided on one side of the third mounting plate 331 along the third direction. Of course, the stopping part can also be provided on one side of the second gear 322, and a locking part can be provided on the second gear 322, so that the locking part can stop the second gear 322 at the stopping part during rotation, which can also realize the rotation of the second gear 322 and the movement of the second rack 333. No further limitations are made here.

[0038] When the second rack 333 stops at the stop, the paper roll is torn. The first drive roller 21 loses the tension of the paper roll and moves to the second position 142 in the second direction under the elastic force of the first elastic element. At this time, the first gear 34 also moves in the second direction along with the first drive roller 21, so that the first gear 34 separates from the gear set 323 and engages with the first rack 332. The first rack 332 moves away from the stop in the third direction under the drag of the second elastic element 334 on the third mounting plate 331, thereby driving the first gear 34 and the first drive roller 21 connected to the first gear 34 to rotate, which in turn can drive the paper roll output between the first drive roller 21 and the second drive roller 22. The paper cutting and feeding mechanism 3 adopts a purely mechanical cooperation structure to realize the automatic paper cutting and continued output after the paper is cut. The structure is simple, convenient to use, does not require additional energy consumption, and saves energy.

[0039] like Figure 5As shown, in order to limit the output length of the paper roll, a limiting part 18 is also provided on the first mounting plate 11. The limiting part 18 is located on the side of the third mounting plate 331 away from the stop part along the third direction. The third mounting plate 331 can stop at the limiting part 18 when it moves along the third direction under the drag of the second elastic member 334, thereby limiting the continued movement of the first rack 332 and stopping the rotation of the first gear 34 and the first transmission roller 21. It is only necessary to ensure the length of the paper roll output part, so as to avoid excessive output and contamination.

[0040] It is worth noting that when the second drive roller 22 is in the second position 142, the first gear 34 meshes with the first rack 332. Under the drag of the paper roll, the teeth of the first rack 332 restrict the first gear 34, which ensures that the first drive roller 21 moves in the second direction. This prevents the first drive roller 21 from rotating directly in the second position 142 and thus failing to achieve the mode switching of the paper feed mechanism 3.

[0041] In this embodiment, a second fixing part 17 protrudes from the first mounting plate 11. The second fixing part 17 is located on the side of the mounting plate away from the stop part. To avoid interference between the second elastic member 334 and the limiting part 18, the second fixing part 17 is located on the side of the limiting part 18 along the paper output direction. The second elastic member 334 connects the second fixing part 17 and the mounting plate. Furthermore, the first elastic member and the second elastic member 334 adopt a tension spring structure in this embodiment. In some embodiments, the first elastic member and the second elastic member 334 can also be springs, but specific examples are not provided here.

[0042] Furthermore, such as Figure 3 As shown, the paper output assembly also includes a cover 4. A mounting groove 15 is formed on one side of the first mounting plate 11 along a first direction. The cover 4 is used to seal the opening of the mounting groove 15. The paper cutting assembly 32 and the paper feeding assembly 33 are both disposed within the mounting groove 15. The third mounting plate 331 is slidably disposed between the cover 4 and the bottom of the mounting groove 15. The second rack 333 can be stopped by the groove wall of the mounting groove 15 when moving along a third direction. By utilizing the mounting groove 15, on the one hand, the groove wall of the mounting groove 15 can act as a stop to stop the second rack 333, eliminating the need for an additional connecting structure, resulting in a simple structure; on the other hand, the restriction of the third mounting plate 331 by the bottom of the mounting groove 15 and the cover 4 can effectively improve the movement guidance and stability of the third mounting plate 331. Of course, placing both the paper cutting assembly 32 and the paper feeding assembly 33 within the mounting groove 15 also provides some protection to the structure, improving the structural installation stability of the paper cutting assembly 32 and the paper feeding assembly 33.

[0043] In addition, to prevent the third mounting plate 331 from tilting, a positioning part can be provided on the side of the third mounting plate 331 facing the bottom of the mounting groove 15. The positioning part is located at one end of the third mounting plate 331 adjacent to the second elastic member 334. A positioning groove is provided at the bottom of the mounting groove 15. The length of the positioning groove extends along the third direction. The positioning part is inserted into the positioning groove. By utilizing the cooperation between the positioning part and the positioning groove, the movement guidance and stability of the end of the third mounting plate 331 adjacent to the second elastic member 334 can be further improved.

[0044] Optionally, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the gear set 323 includes a third gear 3231. A first rotating shaft 321 is rotatably mounted on a first mounting plate 11. A third gear 3231 and a second gear 322 are spaced apart along the outer edge of the first rotating shaft 321 in a first direction. A first gear 34 can mesh with the third gear 3231. That is, the rotation of the first gear 34 drives the rotation of the third gear 3231, which in turn drives the rotation of the first rotating shaft 321 and the second gear 322 on the first rotating shaft 321, thereby realizing the movement of the second rack 333. The structure is simple and the transmission is highly efficient.

[0045] Preferably, the gear set 323 includes a third gear 3231, a second rotating shaft 3232, and a fourth gear 3233. The second gear 322, the third gear 3231, and the fourth gear 3233 are all reduction gears. The second rotating shaft 3232 and the first rotating shaft 321 are fixedly mounted on the first mounting plate 11 at intervals. The length of the second rotating shaft 3232 extends along a first direction. The second gear 322 and the third gear 3231 are rotatably connected to the first rotating shaft 321, and the second gear 322 and the third gear 3231 are spaced apart along the first direction. The fourth gear 3233 is rotatably connected to the second rotating shaft 3232. The first gear 34 can mesh with the third gear 3231, the third gear 3231 meshes with the fourth gear 3233, and the fourth gear 3233 meshes with the second gear 322. That is, the first gear 34 drives the third gear 3231 to rotate, the third gear 3231 drives the fourth gear 3233 to rotate, and the fourth gear 3233 drives the second gear 322 to rotate. The second gear 322, the third gear 3231 and the fourth gear 3233 are all reduction gears, which can gradually reduce the output speed and effectively improve the smoothness of the transmission between the second gear 322 and the second rack 333.

[0046] like Figures 1 to 6 As shown, an embodiment of this utility model also provides a method for operating a paper output assembly. Using the paper output assembly of any of the above embodiments, the method includes the following steps:

[0047] S10. In the initial stage, the paper roll is passed between the first drive roller 21 and the second drive roller 22 of the drive roller group 2 of the paper output assembly, so that the first drive roller 21 and the second drive roller 22 clamp the paper roll.

[0048] S20. During the usage phase, the paper roll is dragged, and the first transmission roller 21 moves from the second position 142 to the first position 141. The paper roll drives the first transmission roller 21 to rotate, and the paper roll is dragged out between the first transmission roller 21 and the second transmission roller 22. The first transmission roller 21 is connected to the paper cutting component 32 of the paper cutting feeding mechanism 3 of the paper output assembly. After the first transmission roller 21 rotates to a specified size, the paper cutting component 32 stops the first transmission roller 21 from rotating, and the paper roll continues to be dragged until it is torn.

[0049] S30. After the paper roll is torn, the switching component 31 drives the first transmission roller 21 to move from the first position 141 to the second position 142. The first transmission roller 21 is connected to the paper feeding assembly 33 of the paper cutting and feeding mechanism 3. The paper feeding assembly 33 can actively rotate the first transmission roller 21, so that the first transmission roller 21 drives the paper roll to continue to output until part of the paper roll is exposed.

[0050] This method is simple to operate. The operator only needs to use one hand to drag the roll of paper, so that when the roll is dragged, it pulls the first drive roller 21 to the first position 141 and connects it with the paper cutting component 32. This allows the first drive roller 21 to rotate a specified size as the roll of paper is dragged, and then the rotation is restricted by the paper cutting component 32 to increase the frictional resistance between the roll of paper and the first drive roller 21, so that the roll of paper can be torn as it continues to be dragged. This realizes the pulling and breaking of the roll of paper, which is convenient and quick to operate and effectively ensures the cleanliness and smoothness of each paper retrieval. After the roll of paper is torn, the first drive roller 21 is pulled to the second position 142 by the switching component 31 and connects it with the paper feeding component 33. This allows the paper feeding component 33 to actively drive the first drive roller 21 to rotate to output part of the roll of paper, ensuring that the paper end of the roll is kept in a proper position and avoiding the situation where the paper end is difficult to pull out, thus ensuring the convenience of each paper retrieval.

[0051] Furthermore, the switching component 31 is a first elastic component, the end of the first transmission roller 21 is connected to the first gear 34, the paper cutting assembly 32 includes a second gear 322 and a gear set 323, and the paper feeding assembly 33 includes a first rack 332 and a second rack 333 that move synchronously back and forth.

[0052] Step S20 includes the following steps:

[0053] S201, dragging the paper roll, the first transmission roller 21 moves from the second position 142 to the first position 141 against the elastic force of the first elastic element, and the first transmission roller 21 and the second transmission roller 22 rotate synchronously, and the first gear 34 rotates together with the first transmission roller 21.

[0054] S202, when the first drive roller 21 is in the second position 142, the first gear 34 is separated from the first rack 332 and continues to drag the paper roll. The first drive roller 21 and the first gear 34 continue to rotate. At this time, the first gear 34 meshes with the second gear 322, the second gear 322 meshes with the second rack 333, and the second rack 333 carries the first rack 332 to move.

[0055] S203, the second rack 333 moves to the stop, the second gear 322 stops rotating, the first gear 34 and the first transmission roller 21 also stop rotating, and continue to drag the paper roll until the paper roll is torn;

[0056] Step S30 includes the following steps:

[0057] S301. After the paper roll is torn, the first transmission roller 21 moves from the first position 141 to the second position 142 under the elastic force of the first elastic element. The first gear 34 meshes with the first rack 332 and separates from the second gear 322. The second gear 322 and the second rack 333 are no longer restricted by external force. Driven by the second elastic element 334, the first rack 332 and the second rack 333 move synchronously in opposite directions and separate from the stop. The first rack 332 meshes with the first gear 34, causing the first transmission roller 21 to continue rotating to continue outputting the paper roll until the first rack 332 returns to the initial position. The first gear 34 and the first transmission roller 21 stop rotating, and the paper roll stops outputting.

[0058] The switching, rotation and stopping of the first transmission roller 21 are achieved by using a purely mechanical paper feeding mechanism 3. The structure is simple, the transmission is efficient, and no additional motor or other active drive structure is required to achieve the drive, saving energy. Moreover, the structural investment cost is low and the economic benefits are high.

[0059] An embodiment of this utility model also provides a tissue box, including a box body and a paper dispensing component of any of the above embodiments. The tissue box has a receiving cavity for accommodating a paper roll, and the tissue box is provided with an outlet communicating with the receiving cavity. The paper dispensing component is disposed in the receiving cavity and is disposed adjacent to the outlet. The paper roll of the paper roll can pass through the paper dispensing component and be pulled out from the outlet.

[0060] This tissue box has a simple structure and is easy to use. The roll of paper simply passes through the first drive roller 21 and the second drive roller 22 of the paper output assembly and is pulled out through the outlet. During use, the paper-cutting and feeding mechanism 3 of the paper output assembly causes the roll of paper to pull the first drive roller 21 to the first position 141, where it is connected to the paper-cutting assembly 32. This allows the first drive roller 21 to rotate a specified distance as the roll of paper is dragged, after which the rotation is restricted by the paper-cutting assembly 32. This increases the frictional resistance between the roll of paper and the first drive roller 21, making the roll... The paper can be torn by continued dragging. Users only need to drag the roll of paper with one hand to pull and break it, which is convenient and quick to operate and effectively ensures the cleanliness and smoothness of each paper retrieval. After the roll of paper is torn, the first drive roller 21 is pulled to the second position 142 under the action of the switching component 31 and is connected to the paper feeding component 33. This allows the paper feeding component 33 to actively drive the first drive roller 21 to rotate and output part of the roll of paper, ensuring that the paper head is kept in a proper position and avoiding the situation where the paper head is difficult to pull out, thus ensuring the convenience of each paper retrieval.
