[0002] The tissue box, as a container for storing wet tissues, dry tissues and cotton soft tissues, needs to break the paper outlet reserved on the box body during use, so that the user can continuously take the tissues out of the box.

[0003] In addition, although some tissue boxes can realize automatic feeding and cutting of tissues at present, the cutting device of the tissue box needs to be driven to move horizontally when cutting the tissues. However, the inventors found that due to the softness and lightness of the tissues, the cutting device cannot cut the soft tissues at one time during the cutting process, and the uncut soft tissues are gathered together again under the horizontal movement of the cutting device, which increases the thickness between them and causes great resistance to the movement of the cutting device, resulting in the cutting device being often stuck with tissues and even being jammed. SUMMARY

[0061] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, those skilled in the art can understand that in the embodiments of the present application, many technical details are proposed in order to make the readers better understand the present application. However, the technical solutions claimed by the present application can be realized even without these technical details and based on various changes and modifications of the following embodiments.

[0062] Example One

[0063] The first embodiment of the present application relates to a cutting mechanism of a soft tissue box, as shown in Figure 1 and Figure 3 , comprising a moving cutter 1, a fixed cutter 2, a driving device 3 and a master control module 4.

[0064] As shown in Figure 1 and Figure 3 , the moving cutter 1 and the fixed cutter 2 are arranged opposite and parallel to each other, and the moving cutter 1 can move linearly relative to the fixed cutter 2. In addition, the driving device 3 is also connected with the moving cutter 1, and the driving device 3 is used for receiving a driving signal and driving the moving cutter 1 to move towards the fixed cutter 2 after receiving the driving signal.

[0065] Finally, as shown in Figure 4 , the master control module 4 is electrically connected with the driving device 3, and the master control module 4 is used for judging whether to output a driving signal to the driving device 3 according to a received soft tissue output instruction.

[0066] From the above, it can be seen that since the moving cutter 1 and the fixed cutter 2 of the cutting mechanism are arranged opposite and parallel to each other, and the driving device 3 can drive the moving cutter 1 to move linearly relative to the fixed cutter 2, and when the driving device 3 receives the driving signal output by the master control module, it can drive the moving cutter 1 to move towards the fixed cutter 2, and when the moving cutter 1 moves to a preset position, the moving cutter 1 is attached to the fixed cutter 2, so that the cutting of the soft tissue can be realized. It can be found that the cutting direction of the moving cutter 1 and the fixed cutter 2 relative to the soft tissue, so that the soft tissue will not be subjected to a horizontal resistance when the moving cutter 1 and the fixed cutter 2 cut the soft tissue, so that the soft tissue will not be gathered on one side, thereby effectively improving the success rate of cutting the soft tissue by the cutting mechanism once, and when the soft tissue cannot be cut once, since the moving cutter 1 can move linearly away from the fixed cutter 2, the phenomenon of the cutting mechanism being stuck can be well avoided.

[0067] Specifically, in the present embodiment, as shown in Figure 1 , the moving cutter 1 has a first cutting edge 11 on one side relative to the fixed cutter 2, and the fixed cutter 2 has a second cutting edge 21 on one side relative to the moving cutter 1, and when the driving device 3 drives the moving cutter 1 to move towards the fixed cutter 2 to a preset position, the first cutting edge 11 of the moving cutter 1 and the second cutting edge 21 of the fixed cutter 2 are attached, so that the cutting of the soft tissue can be realized. In addition, in order to enable the driving device 3 to drive the moving cutter 1 to move linearly relative to the fixed cutter 2, as shown in Figure 4 , the driving device 3 comprises a connecting rod assembly 31 and a driving assembly 32. As shown in Figure 1 and Figure 3 , the connecting rod assembly 31 is connected with the moving cutter 1, and the driving assembly 32 is connected with the connecting rod assembly 31.As shown in

[0068] In addition, it is worth mentioning that, as shown in Figure 1 and Figure 3 The link assembly 31 includes a first link 311 and a second link 312, wherein the first link 311 has a first connecting end 3111 slidably connected with the moving knife 1, a first driving end 3112 disposed away from the first connecting end 3111, a first pivot end 3113 disposed between the first connecting end 3111 and the first driving end 3112, and the first connecting end 3111 is slidable along the length direction of the moving knife. Secondly, as shown in Figure 1 and Figure 3 The second link 312 has a second connecting end 3121 slidably connected with the moving knife 1, a second driving end 3122 disposed away from the second connecting end 3121, a second pivot end 3123 disposed between the second connecting end 3121 and the second driving end 3122, and the second connecting end 3121 is slidable along the length direction of the moving knife 1. In actual application, the driving assembly 32 is used to synchronously drive the first driving end 3112 and the second driving end 3122, so that the first link 311 rotates about the first pivot end 3113 and the second link 312 rotates about the second pivot end 3123. It is worth noting that, in order to realize the sliding connection between the first connecting end 3111 and the moving knife 1, as shown in Figure 1 and Figure 3 The moving knife 1 is provided with a first waist-shaped groove 12 along the length direction thereof, and the moving knife 1 can be slidably connected with the first connecting end 3111 through the first waist-shaped groove 12. Similarly, in order to realize the sliding connection between the second connecting end 3121 and the moving knife 1, the moving knife 1 is provided with a second waist-shaped groove 13 along the length direction thereof, and the moving knife 1 can be slidably connected with the second connecting end 3121 through the second waist-shaped groove 13. Therefore, when the driving assembly 32 synchronously drives the first driving end 3112 and the second driving end 3122, so that the first link 311 rotates about the first pivot end 3113 and the second link 312 rotates about the second pivot end 3123, the first connecting end 3111 and the second connecting end 3121 can be respectively lifted by the first waist-shaped groove 12 and the second waist-shaped groove 13 to move the moving knife 1 as a whole towards the stationary knife 2, so that the moving knife 1 can cooperate with the stationary knife 2 to cut the soft towel. In actual application, in combination with Figure 1 、 Figure 2 and Figure 3As shown, a support 6 can be arranged, and the support 6 is respectively rotationally connected with the first pivot end 3113 of the first connecting rod 311 and the second pivot end 3123 of the second connecting rod 312. Through the rotational connection of the support 6 with the first pivot end 3113 and the second pivot end 3123, not only can the first connecting rod 311 and the second connecting rod 312 be supported, but also the first connecting rod 311 can rotate relative to the second connecting rod 312 with the first pivot end 3113 as the fulcrum and the second pivot end 3123 as the fulcrum.

[0069] In addition, in order to enable the driving assembly 32 to drive the first connecting rod 311 and the second connecting rod 312 to rotate relative to each other, the driving assembly 32 is connected with the first connecting rod 311 and the second connecting rod 312. Figure 2 As shown, the driving assembly 32 includes a driving rod 321 and a driving module 322. The driving rod 321 is rotatable about a preset axis as a pivot axis. The driving module 322 is connected with the driving rod 321 and is electrically connected with the main control module 4. In actual application, the driving module 322 is configured to receive a driving signal output by the main control module 4 and to drive the driving rod 321 to rotate about the preset axis as a pivot axis after receiving the driving signal. In addition, as shown, Figure 1 and 3 As shown, the driving rod 321 can also abut against the first driving end 3112 and the second driving end 3122 respectively when rotating, so as to drive the first driving end 3112 and the second driving end 3122 to move in directions away from each other, and drive the first connecting end 3111 and the second connecting end 3121 to move in directions close to the fixed knife 2, so as to lift the movable knife 1 in the direction of the fixed knife 2.

[0070] Meanwhile, after the driving assembly 32 drives the driving rod 321 to rotate to a preset angle, the driving rod 321 can be separated from the first driving end 3112 and the second driving end 3122 through Figure 1 and Figure 3 As can be seen, the first connecting rod 311 and the second connecting rod 312 can move in directions away from the fixed knife 2 under the gravity of the movable knife 1, so as to drive the first connecting end 3111 and the second connecting end 3121 to move in directions away from the fixed knife 2, and drive the first driving end 3112 and the second driving end 3122 to move in directions close to each other, so as to reset the movable knife 1. In addition, since the first driving end 3112 and the second driving end 3122 move in directions away from each other when the driving rod 321 rotates, in order to enable the first connecting end 3111 of the first connecting rod 311 and the second connecting end 3121 of the second connecting rod 312 to move in the direction of the fixed knife 2 at the same time, as shown, Figure 1 and Figure 3As shown, the second connecting rod 312 comprises: a driving segment 3124 with a second driving end 3122, a driven segment 3125 with a second connecting end 3121 and a second pivot end 3123. And, one end of the driving segment 3124 away from the second driving end 3122 is hinged with one end of the driven segment 3125 away from the second connecting end 3121, so that when the second driving end 3122 is driven to move away from the first driving end 3112, the driving segment 3124 can drive the driven segment 3125 to rotate towards the first connecting rod 311, so that the first connecting end 3111 and the second connecting end 3121 can lift the movable cutter 1 towards the fixed cutter 2. And, as a preferred solution, as shown in Figure 1 and Figure 3 As shown, the second connecting rod 312 further comprises a third pivot end 3126, and the third pivot end 3126 is arranged on the driving segment 3124, so that after the second driving end 3122 is driven by the driving rod 321, the driving segment 3124 can rotate around the third pivot end 3126. And, it should be noted that in the present embodiment, the driven segment 3125 is approximately in a V-shaped structure, so that the driven segment 3125 can be more easily rotated towards the first connecting rod 311 under the rotation driving of the driving segment 3124.

[0071] In addition, as shown in Figure 1 Since the driving rod 321 can be separated from the first driving end 3112 and the second driving end 3122 after rotating by a preset angle, in order to enable the movable cutter 1 and the fixed cutter 2 to be closed in time after completing the cutting of the soft towel, as shown in Figure 4 The cutting mechanism of the present embodiment further comprises a detection module 5, and the detection module 5 is electrically connected with the main control module 4. In actual application, the detection module 5 is used to detect the rotation angle of the driving rod 321 when rotating, and when the detection module 5 detects that the rotation angle of the driving rod 321 reaches a preset angle, the main control module 4 can directly close the driving module 322, so that the driving module 322 can immediately stop driving the driving rod 321, thereby ensuring that the movable cutter 1 is in the initial position away from the fixed cutter 2, and thus does not affect the subsequent soft towel. And, it should be noted that in the present embodiment, the detection module 5 can adopt an encoder coaxially connected with the driving rod 321, and the encoder can accurately detect the rotation angle of the driving rod 321 when rotating. Of course, in actual application, the detection module 5 can also adopt other detection elements, and in the present embodiment, the type of the detection module 5 is not limited.

[0072] In addition, it is worth mentioning that in order to enable the driving module 322 to drive the driving rod 321 to rotate, as shown in Figure 1 , Figure 2 and Figure 3As shown, the drive module 322 includes: a motor 3221, a drive gear 3222, a drive gear 3224, and a gear set 3223. The motor 3221 is electrically connected to the main control module 4, and is used to receive drive signals output by the main control module 4. Furthermore, as... Figure 2 As shown, the drive gear 3222 is coaxially connected to the main shaft of the motor 3221. Simultaneously, the drive gear 3224 is coaxially connected to the drive rod 321 along a preset axis. Finally, the gear set 3223 meshes with both the drive gear 3222 and the drive gear 3224. In practical applications, when the motor 3221 receives the drive signal output from the main control module 4, it can drive the drive gear 3222 to rotate via its main shaft. The gear set 3223 can then transmit power under the rotation of the drive gear 3222, thereby driving the drive gear 3224 to rotate. The rotation of the drive gear 3224 drives the drive rod 321, allowing it to rotate with the preset axis as its pivot axis.

[0073] Furthermore, it should be noted that, in order to enable the gear set 3223 to drive the drive gear 3224 under the rotation of the drive gear 3222, in this embodiment, the gear set 3223 includes: a first driven gear 32231 meshing with the drive gear 3222, a second driven gear 32232 coaxially connected to the first driven gear 32231, a third driven gear 32233 meshing with the second driven gear 32232, a fourth driven gear 32234 coaxially connected to the third driven gear 32233, a fifth driven gear 32235 meshing with the fourth driven gear 32234, a sixth driven gear 32236 coaxially connected to the fifth driven gear 32235, and a seventh driven gear 32237 meshing with the sixth driven gear 32236 and the drive gear 3224 respectively. It is easy to see that the drive rod 321 can be driven by the meshing transmission between the driven gears in the gear set 3223 and the meshing transmission between the drive gear 3222 and the driving gear 3224.

[0074] In addition, it is worth mentioning that in some embodiments, the fixed knife 2 can also be inclined relative to the moving knife 1, that is, the first blade edge 11 of the moving knife 1 and the second blade edge 21 of the fixed knife 2 are arranged in a staggered manner relative to each other. Therefore, as a preferred scheme, when the moving knife 1 moves to the preset position in the direction of approaching the fixed knife 2, the preset position is not the limit position of the moving knife 1 moving in the direction of approaching the fixed knife 2, that is, the distance of the moving knife 1 moving to the limit position is greater than the distance of the moving knife 1 moving to the preset position. Therefore, when the moving knife 1 has not moved to the limit position in the direction of the fixed knife 2, the first blade edge 11 and the second blade edge 21 are already in contact with each other. When the moving knife 1 continues to move to the limit position in the direction of the fixed knife 2, the first blade edge 11 can slightly pass through the second blade edge 21, so that the first blade edge 11 and the second blade edge 21 not only contact each other, but also stagger relative to each other, thereby further increasing the shearing force of the moving knife 1 and the fixed knife 2 when cutting the soft towel, so that the cutting mechanism has a better cutting effect on the soft towel.

[0075] Embodiment two

[0076] The second embodiment of the present application relates to a soft towel box, as shown in Figure 5 and Figure 6 , comprising a shell 9, a transmission mechanism 7, and a cutting mechanism as described in the first embodiment.

[0077] As shown in Figure 5 , the shell 9 is used to accommodate the soft towel consumables, and the shell 9 also has a towel outlet side 91. Secondly, as shown in Figure 6 , the transmission mechanism 7 is electrically connected with the main control module 3, and the main control module 3 is used to open the transmission mechanism 7 according to the received towel outlet instruction, so that the transmission mechanism 7 transmits the soft towel 100 in the soft towel consumables in the direction of the towel outlet side 91.

[0078] In addition, as shown in Figure 6 , the main control module 3 is also used to close the transmission mechanism 7 when the length of the soft towel conveyed in the direction of the towel outlet side 91 reaches the length of one time of the towel outlet, and to determine to output a driving signal to the driving device 2. After receiving the driving signal, the driving device 2 can drive the cutting device 1 to move in a predetermined straight line direction, so as to realize the cutting of the soft towel.

[0079] It can be seen from the above that the cutter 1 and the fixed cutter 2 are arranged in parallel relative to each other, and the driving device 3 can drive the cutter 1 to move linearly relative to the fixed cutter 2, and when the driving device 3 receives the driving signal output by the master module, the cutter 1 can be driven to move towards the fixed cutter 2, so that the cutting of the soft towel can be realized. It can be found that the cutting direction of the cutter 1 and the fixed cutter 2 relative to the soft towel, so that the soft towel will not be gathered to one side when the cutter 1 and the fixed cutter 2 cut the soft towel, thereby effectively improving the success rate of cutting the soft towel once by the cutting mechanism, and when the soft towel cannot be cut once, the cutter 1 can move linearly away from the fixed cutter 2, so that the cutting mechanism can be prevented from being stuck.

[0080] Embodiment three

[0081] The third embodiment of the present application relates to a cutting method of a soft towel, as shown in the formula (I), comprising the following steps: Figure 7

[0082] In step 710, it is judged whether the soft towel is cut according to the received soft towel output instruction.

[0083] In step 720, if it is judged that the soft towel is cut, the cutter 1 of the soft towel box is driven to move towards the fixed cutter 2 of the soft towel box, so that the first blade edge 11 of the cutter 1 is in contact with the second blade edge 21 of the fixed cutter 2.

[0084] It can be seen from the above that the cutting direction of the cutter 1 and the fixed cutter 2 relative to the soft towel, so that the soft towel will not be gathered to one side when the cutter 1 and the fixed cutter 2 cut the soft towel, thereby effectively improving the success rate of cutting the soft towel once by the cutting mechanism, and when the soft towel cannot be cut once, the cutter 1 can move linearly away from the fixed cutter 2, so that the cutting mechanism can be prevented from being stuck.

[0085] Specifically, in the step of judging whether the soft towel is cut according to the received soft towel output instruction, that is, step 710, specifically includes:

[0086] The length of the soft towel sent out from the soft towel box is calculated.

[0087] If the length of the soft towel sent out from the soft towel box reaches the length of the soft towel output once, it is judged that the soft towel is cut.

[0088] If the length of the soft towel sent out from the soft towel box does not reach the length of the soft towel output once, it is judged that the soft towel is not cut.

[0089] ​Since the total length of the wipes in the present embodiment is the system default length when the wipes consumable is not out of the wipes, and the length of the wipes consumable out of the wipes at a time is the fixed length of the wipes out of the wipes, i.e., the length of the wipes out of the wipes at each time is a certain amount, or the length of the wipes consumable out of the wipes at a time is the pre-set length, i.e., the length of the wipes out of the wipes at each time is a variable, which can be pre-set by the user. Therefore, only when the length of the wipes sent out from the out-of-wipes side reaches the length of the wipes out of the wipes at a time, the wipes box will determine to cut the wipes, so as to ensure the consistency of the length of the wipes out of the wipes at each time. And when it is determined not to cut the wipes, it returns to step 710.

[0090] In addition, as a preferred embodiment, after the moving cutter 1 driving the wipes box moves relative to the fixed cutter 2 of the wipes box, i.e., after step 720, as shown in the figure, the cutting method of the present embodiment further includes the following steps: Figure 7

[0091] Step 730, continue to determine whether the remaining length of the wipes in the wipes consumable is less than the length of the wipes out of the wipes at a time.

[0092] Step 740, if it is determined that the remaining length of the wipes in the wipes consumable is less than the length of the wipes out of the wipes at a time, an alarm information is generated for alarm prompt. For example, the alarm information generated by the wipes box is sound alarm information or light alarm information, therefore, corresponding to the sound alarm information or light alarm information, an alarm module (not shown in the figure) can be provided on the wipes box, and the alarm module can adopt, for example, a light alarm module, a sound alarm module or a sound and light alarm module. As can be seen, once the wipes box determines that the remaining length of the wipes in the wipes consumable is less than the length of the wipes out of the wipes at a time, it indicates that the amount of the wipes in the wipes consumable at this time is insufficient, and by generating alarm information for alarm prompt, the purpose of reminding the user can be achieved, which is convenient for the user to replace the consumable in the wipes box in time.

[0093] And it should be noted that since the length of the wipes out of the wipes at a time is fixed, the remaining length of the wipes in the wipes consumable is related to the number of times of the wipes out of the wipes, for example, if the length of the wipes out of the wipes at a time is 10 cm, the length of the wipes out of the wipes for 10 times is 100 cm. Therefore, in the step of determining whether the remaining length of the wipes in the wipes consumable is less than the length of the wipes out of the wipes at a time, i.e., step 730, specifically includes;

[0094] According to the number of times of the wipes out of the wipes, the total length of the wipes sent out from the out-of-wipes side is obtained.

[0095] The length difference between the total length of the wipes and the total length of the wipes sent out is calculated.

[0096] If the calculated length difference is less than the length of the wipes out of the wipes at a time, it is determined that the remaining length of the wipes in the wipes consumable is less than the length of the wipes out of the wipes at a time.

[0097] ​If the calculated length difference is greater than or equal to the length of one-time wiping, it is determined that the remaining length of the soft wipes in the soft wipe consumable is not less than the length of one-time wiping.

[0098] It can be seen that, by obtaining the number of times of wiping of the soft wipe box, the total length of wiping from the wiping side can be obtained, so that the calculation of the remaining length of the soft wipes in the soft wipe consumable is simple and easy to operate. In actual application, a counter is arranged at the position of the wiping side of the soft wipe box, and the number of times of wiping of the soft wipe box is accumulated by the counter. The total length of wiping of the soft wipe box can be calculated according to the number of times of wiping accumulated by the counter.

[0099] After receiving the wiping instruction and before determining whether to cut the soft wipe, and before step 710, the cutting method of the embodiment further includes the following steps. Figure 7

[0100] Step 707: Determine whether the movable knife 1 is in the initial position away from the fixed knife 2.

[0101] Step 708: If it is determined that the movable knife 1 is not in the initial position away from the fixed knife 2, drive the movable knife 1 of the soft wipe box to move towards the fixed knife 2.

[0102] Step 709: If it is determined that the movable knife 1 is in the initial position away from the fixed knife 2, transmit the soft wipe in the soft wipe box towards the wiping side of the soft wipe box.

[0103] In addition, after determining not to cut the soft wipe, that is, after step 710, it indicates that the length of the soft wipe transmitted from the wiping side does not reach the length of one-time wiping at this time, and step 709 can be returned to continue transmitting the soft wipe in the soft wipe box towards the wiping side.

[0104] It can be seen that, by determining whether the movable knife 1 is in the initial position before determining whether to cut the soft wipe, the soft wipe is transmitted from the wiping side only when it is determined that the movable knife 1 is in the initial position away from the fixed knife 2, so that the movable knife 1 and the fixed knife 2 are separated from each other when the soft wipe is wiped, and it is ensured that the movable knife 1 does not interfere with the wiping of the soft wipe.

[0105] In addition, it is worth noting that the embodiment of the cutting method of the soft wipe corresponds to the first embodiment, and the embodiment can be implemented in cooperation with the first embodiment. The related technical details mentioned in the first embodiment are still valid in the embodiment, and in order to reduce repetition, they will not be described here. Correspondingly, the related technical details mentioned in the embodiment can also be applied in the first embodiment.

[0106] ​Those skilled in the art can understand that the above-mentioned embodiments are specific embodiments for realizing the present application, and in actual applications, various changes can be made in form and details without departing from the spirit and scope of the present application.
