Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those of ordinary skill in the art will understand that in various embodiments of the present invention, numerous technical details have been set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments.

Example 1

A first embodiment of the present invention relates to a cutter moving method for moving a cutter of a soft towel box, and as shown in fig. 1 and 3, the cutter moving method includes the steps of:

step 110, when the driving device 2 of the soft towel box drives the cutter 11 to move, judging whether the cutter 11 is blocked.

And 120, if the cutter 11 is blocked, sending out prompt information.

Through the above, it is difficult to see that, because the driving device 2 can judge whether the cutter 11 is blocked when driving the cutter 11 to move, in case it is judged that the cutter 11 is blocked, prompt information can be sent out to reach the purpose of reminding a user, so that the user can timely remove faults, and further, the phenomenon of blocking caused by the cutter can be effectively avoided, and the influence on the subsequent towel discharging of the soft towel box is caused.

Specifically, in this embodiment, when the prompt message is sent, the corresponding prompt message may be any message playing a role in prompting, for example, an acoustic alarm message or an optical alarm message. In this embodiment, as shown in fig. 4 and 5, the soft towel box is provided with an alarm module as the prompt module 10, and the alarm module may employ, for example: the light alarm module, the sound alarm module or the sound and light alarm module can control the prompt module 10 to work by the main control module 3 of the soft towel box once the judging cutter 11 is blocked, so that the prompt module 10 sends out prompt information to realize sound alarm prompt and/or light alarm prompt. The prompting information sent by the soft towel box can be error code information, and the prompting information corresponds to the error code information, and the soft towel box can be provided with a display module as the prompting module 10, for example, a display screen, when judging that the soft towel consumable 2 lacks towel, the error code information can be called and displayed through the display module, and the purpose of reminding a user can be achieved through the mode.

In addition, in the present embodiment, after determining whether the cutter is blocked, that is, after step 110, as shown in fig. 1, the cutter movement method of the present embodiment further includes the following sub-steps:

step 130, if it is determined that the cutter is not blocked, entering a standby mode after the cutter 11 moves to a preset position; or after the cutter 11 moves to a preset position, executing towel discharging action according to the received towel discharging instruction. Since the movement of the cutter 11 is divided into two forms, one is the movement of the cutter 11 when cutting a soft towel, and the other is the reset movement of the cutter 11, as shown in fig. 3. Therefore, when the cutter 11 is cutting the soft towel, if it is determined that the cutter 11 is not blocked, the soft towel box can directly enter the standby mode after the cutter 11 completes cutting the soft towel. In some embodiments, after the cutter 11 completes cutting the soft towel, or before the cutter 11 cuts the soft towel, the cutter 11 needs to be reset, and when the cutter 11 is in the reset, if it is determined that the cutter 11 is not blocked, the soft towel box can directly enter the standby mode when the cutter 11 moves to a preset position, or the towel discharging action can be performed according to the received towel discharging instruction.

It is thus readily apparent that, due to the movement of the cutter blade 11, both when the towel 2 is cut and when reset, the towel box will enter a standby mode when the cutter blade 11 is moved to a preset position, or perform a towel discharging action according to a received towel discharging instruction. Therefore, in order to avoid that the stay position of the cutter blade 11 blocks the cutting area of the cut-out soft towel, thereby affecting the subsequent towel discharging of the soft towel box, the preset position mentioned in the embodiment is any position where the cutter blade 11 leaves the cutting area of the cut-out soft towel. However, preferably, the preset position is a start position or a stop position on the cutting path when the cutter blade 11 moves along the cutting path, so that the cutter blade 11 needs to move to the start position or the stop position during both the movement and the reset movement of the cutter blade 11.

In addition, because the cutter 11 is blocked, more because in the process of cutting the soft towel, the soft towel is not cut by the cutter 11 in time, so that the part of the soft towel which is not cut can block the movement of the cutter 11, and the driving device 2 can not drive the cutter 11 to continue to move, therefore, in order to prevent the cutter 11 from being blocked, the soft towel box can automatically eliminate the blocking phenomenon of the cutter 11 under certain working conditions. In some embodiments, when the preset position is the start position, as shown in fig. 1, after determining whether the cutter 11 is blocked, i.e. after step 110, and before sending the prompt message, i.e. before step 120, as shown in fig. 1, the cutter movement method of the present embodiment further includes the following steps:

In step 111a, it is determined whether the cutter 11 is at a termination position far from the start position. If it is determined that the cutter 11 is at the end position, step 120 is performed.

In step 112a, if it is determined that the cutter 11 is not at the end position, the driving device 2 is controlled to drive the cutter 11 to move toward the end position.

In step 114a, when the cutter moves to the end position, the driving device 2 is controlled again, so that the driving device 2 drives the cutter 11 to move towards the start position again.

Step 115a, it is again judged whether or not the cutter 11 is blocked. If it is determined that the cutter 11 is blocked, step 120 is performed, i.e., a prompt message is sent.

It is thus clear that, once the cutter 11 is blocked in the process of moving toward the start position, as shown in fig. 3, it can be firstly determined whether the cutter 11 is at the end position far away from the start position, once it is determined that the cutter 11 is not at the end position, the driving device 2 can be controlled to drive the cutter 11 to move toward the end position, and when the driving device 2 drives the cutter 11 to move to the end position, the driving device 2 can only re-drive the cutter 11 to move toward the start position, so that the blocking phenomenon of the cutter 11 can be eliminated to a certain extent by means of the reverse movement of the cutter 11. For example, when the soft towel box needs to be cut, as the driving device 2 drives the cutter 11 to move towards the direction of the initial position, once the soft towel cannot be cut by the cutter 11, the soft towel is folded or curled, so that a larger resistance is caused to the movement of the cutter 11, the cutter 11 is blocked in the process of cutting the soft towel, in order to eliminate the phenomenon, the driving device 2 can be controlled to drive the cutter 11 to move towards the direction of the final position, namely, the cutter 11 is driven to move reversely, so that the blocking phenomenon of the current cutter 11 can be eliminated, and after the cutter 11 moves to the final position, the driving device 2 can be controlled to drive the cutter 11 to move towards the direction of the initial position again, so that secondary cutting of the soft towel is realized, for example, the cutter 11 is still blocked in the process of secondary cutting of the soft towel, namely, the blocking phenomenon of the cutter 11 cannot be eliminated by means of the cutter 11 is explained, at the moment, the prompt module 10 can be controlled to send prompt information, and the blocking phenomenon of the cutter 11 can be eliminated timely by a user.

However, the above-described manner of driving the cutter 11 to perform the directional movement can be performed only when it is determined that the cutter 11 is not at the end position away from the start position. When the cutter 11 is determined to be at the end position far from the start position, the cutter 11 cannot eliminate the blocking phenomenon of the cutter 11 in a reverse movement manner, so that once the blocking position of the cutter 11 is at the end position, the prompt module 10 needs to be immediately controlled to send prompt information, and a user needs to be timely reminded to eliminate the blocking phenomenon of the cutter 11 by means of manual operation.

In addition, it should be noted that, since the cutter 11 may be blocked during the process of controlling the driving device 2 to drive the cutter 11 to move toward the end position, in some embodiments, after controlling the driving device 2 to drive the cutter 11 to move toward the end position, that is, after step 112a and before the moving cutter moves to the end position, as shown in fig. 1, the cutter movement method of the present embodiment further includes the following steps:

step 113a, judging whether the cutter 11 is secondarily blocked. If it is determined that the cutter 11 is blocked secondarily, step 120 is executed, i.e. a prompt message is sent. If it is determined that the cutter 11 is not secondarily blocked, the process proceeds to step 114a.

Therefore, it can be seen that when the driving device 2 drives the cutter 11 to move towards the direction of the termination position, the cutter 11 can be judged whether to secondarily block, and the cutter 11 is judged to secondarily block, which indicates that the cutter cannot eliminate the blocking phenomenon in a reverse movement mode, so that the prompt module 10 needs to be immediately controlled to send prompt information, and a user needs to be timely reminded of eliminating the blocking phenomenon of the cutter 11 by means of manual operation.

Similarly, when the preset position is the end position, the manner of eliminating the blocking phenomenon of the cutter blade 11 by the soft towel box is substantially the same as the manner of eliminating the blocking phenomenon of the cutter blade 11 when the preset position is the start position, specifically, when the preset position is the end position, after judging whether the cutter blade 11 is blocked, i.e. after step 110, and before sending the prompt message, i.e. before step 120, as shown in fig. 2 and 3, the cutter blade movement method of the embodiment further includes the following steps:

step 111b, determining whether the cutter 11 is at the start position far from the end position. If it is determined that the cutter 11 is at the start position, step 120 is executed, i.e. a prompt message is sent.

In step 112b, if it is determined that the cutter 11 is not at the start position, the driving device 2 is controlled to drive the cutter 11 to move toward the start position.

Step 114b, when the cutter 11 moves to the start position, the driving device 2 is controlled again, so that the driving device 2 drives the cutter 11 to move towards the end position again.

Step 115b, it is again judged whether or not the cutter 11 is blocked. If it is determined that the cutter 11 is blocked, step 120 is performed, i.e., a prompt message is sent.

Also, since the cutter blade 11 may be blocked during the process of controlling the driving device 2 to drive the cutter blade 11 toward the start position, in some embodiments, after controlling the driving device 2 to drive the cutter blade 11 toward the end position, that is, after step 112b and before the cutter blade moves to the start position, the cutter blade moving method of the present embodiment further includes, as shown in fig. 2 and 3, the following steps:

step 113b, judging whether the cutter 11 is secondarily blocked. If it is determined that the cutter 11 is blocked secondarily, step 120 is executed, i.e. a prompt message is sent. If it is determined that the cutter 11 is not secondarily blocked, the process proceeds to step 114b.

In addition, when the driving device 2 drives the cutter 11 to move toward the preset position, in order to accurately determine whether the cutter 11 is blocked, in the step of determining whether the cutter 11 is blocked, that is, step 110 specifically includes:

The time period when the cutter 11 moves to the preset position is acquired.

If the obtained time period is greater than or equal to the preset time period, it is determined that the cutter 11 is blocked.

If the obtained time period is less than the preset time period, it is determined that the cutter 11 is not blocked.

Specifically, as shown in fig. 4 and 5, the first detecting module 5 may be disposed at the start position and the second detecting module 6 may be disposed at the end position along the cutting path of the cutter 11, and when the cutter 11 moves to the start position, the cutter 11 may be detected by the first detecting module 5, so that the first detecting module 5 may output the first electrical signal to the main control module 3 of the soft towel box, and similarly, when the cutter 11 moves to the end position, the cutter 11 may be detected by the second detecting module 6, so that the second detecting module 6 may output the second electrical signal to the main control module 3 of the soft towel box. Therefore, when the preset position is the start position, the main control module 3 receives the first electrical signal output by the first detection module 5, which indicates that the cutter 11 moves to the preset position, and when the preset position is the end position, the main control module 3 receives the second electrical signal output by the second detection module 6, which indicates that the cutter 11 moves to the preset position.

In addition, corresponding to the first detection module 5 and the second detection module 6, a timing module 20 electrically connected to the main control module 3 is further disposed in the towel box, as shown in fig. 4, for example, when the preset position is the start position, and meanwhile, when the driving device 2 drives the cutter 11 to move towards the start position, the timing module 20 may count the movement duration of the cutter 11, and upload the counted duration to the main control module 3, once the counted duration of the timing module 20 is greater than or equal to the preset duration, it is indicated that the main control module 3 does not receive the first electrical signal within the preset duration, that is, the first detection module 5 does not detect the cutter 11, and then it can be determined that the cutter 11 is blocked.

Similarly, when the driving device 2 drives the cutter 11 to move toward the end position, in order to accurately determine whether the cutter 11 is secondarily blocked, in the step of determining whether the cutter is secondarily blocked, that is, step 114a specifically includes:

the time period when the cutter 11 moves to the end position is acquired.

If the obtained time length is greater than or equal to the preset time length, judging that the cutter 11 is blocked secondarily;

if the obtained time period is less than the preset time period, it is determined that the cutter 11 is not secondarily blocked.

It can be seen from this that, when the driving device 2 drives the cutter 11 to move towards the direction of the termination position, as shown in fig. 3 and 4, the timing module 20 can also count the movement duration of the cutter 11, and upload the counted duration to the main control module 3, once the counted duration of the timing module 20 is greater than or equal to the preset duration, it is indicated that the main control module 3 does not receive the second electrical signal within the preset duration, that is, the second detection module 6 does not detect the cutter 11, and at this time, it can be determined that the cutter 11 is blocked secondarily.

For example, when the preset position is the end position, the judging mode of whether the cutter 11 is blocked by the soft towel box is similar to the above mode, specifically, when the cutter 11 is driven by the driving device 2 to move towards the direction of the end position by the soft towel box, the timing module 20 can count the movement time of the cutter 11 and upload the counted time to the main control module 3, once the counted time of the timing module 20 is greater than or equal to the preset time, the main control module 3 does not receive the second electric signal within the preset time, that is, the cutter 11 is not detected by the second detection module 6, and the cutter 11 can be judged to be blocked at the moment.

Similarly, when the driving device 2 drives the cutter 11 to move toward the direction of the start position, in order to accurately determine whether the cutter 11 is secondarily blocked, the manner of determining whether the cutter 11 is secondarily blocked may be similar to the above manner, specifically, in the step of determining whether the cutter is secondarily blocked, that is, the step 114b specifically includes:

the time period when the cutter 11 moves to the start position is acquired.

It can be seen from this that, as shown in fig. 4, when the driving device 2 drives the cutter 11 to move towards the direction of the start position, the timing module 20 can also count the movement duration of the cutter 11, and upload the counted duration to the main control module 3, once the counted duration of the timing module 20 is greater than or equal to the preset duration, it is indicated that the main control module 3 does not receive the first electrical signal within the preset duration, that is, the first detection module 5 does not detect the cutter 11, and it can be determined that the cutter 11 is secondarily blocked at this time.

However, as an alternative, in some embodiments, when the driving device 2 drives the cutter 11 to move toward the preset position, it may also be determined whether the cutter 11 is blocked, that is, step 110 specifically includes:

The current value of the driving device 2 when driving the cutter 11 to move to the preset position is detected.

If the detected current value of the driving device 2 is greater than or equal to the preset value, it is determined that the cutter 11 is blocked.

If the detected current value of the driving device 2 is smaller than the preset value, it is determined that the cutter 11 is not blocked.

Specifically, as shown in fig. 5, a current detection module 30, such as a current sensor, electrically connected to the main control module 3 may be disposed in the towel box, for example, when the preset position is the start position, and meanwhile, when the driving device 2 drives the cutter 11 to move towards the start position, the current detection module 30 may detect the current value of the driving device 2 and upload the detected current value to the main control module 3, and once the current value detected by the current detection module 30 is greater than or equal to the preset value, it is indicated that the cutter 11 is blocked in the process of moving towards the start position, so that the current value of the driving device 2 rises rapidly and exceeds the preset value, and it can be determined that the cutter 11 is blocked at this time.

Similarly, as shown in fig. 1, when the driving device 2 drives the cutter 11 to move toward the end position, in order to accurately determine whether the cutter 11 is secondarily blocked, in the step of determining whether the cutter is secondarily blocked, that is, step 114a specifically includes:

The current value of the driving device 2 when driving the cutter 11 to the end position is detected.

If the detected current value of the driving device 2 is greater than or equal to the preset value, it is determined that the cutter 11 is secondarily blocked.

If the detected current value of the driving device 2 is smaller than the preset value, it is determined that the cutter 11 is not secondarily blocked.

It can be seen from this that, when the driving device 2 drives the cutter 11 to move toward the end position, the current detection module 30 can also detect the current value of the driving device 2 and upload the detected current value to the main control module 3, and once the current value detected by the current detection module 30 is greater than or equal to the preset value, it is indicated that the cutter 11 is blocked in the process of moving toward the end position, so that the current value of the driving device 2 rises rapidly and exceeds the preset value, and it can be determined that the cutter 11 is blocked secondarily at this time.

For example, when the preset position is the end position, the judging mode of whether the cutter 11 is blocked by the soft towel box is similar to the above mode, specifically, as shown in fig. 3 and 5, when the cutter 11 is driven by the driving device 2 to move towards the direction of the end position by the soft towel box, the current detection module 30 can detect the current value of the driving device 2 and upload the detected current value to the main control module 3, so when the time length obtained by the main control module 3 is greater than or equal to the preset value, it is indicated that the cutter 11 is blocked in the process of moving towards the end position, the current value of the driving device 2 is rapidly increased and exceeds the preset value, and the cutter 11 can be judged to be blocked at the moment.

Similarly, as shown in fig. 2, when the driving device 2 drives the cutter 11 to move toward the direction of the start position, in order to accurately determine whether the cutter 11 is secondarily blocked, the manner of determining whether the cutter 11 is secondarily blocked may be similar to the above manner, specifically, in the step of determining whether the cutter is secondarily blocked, that is, step 114b specifically includes:

the current value of the driving device 2 when driving the cutter 11 to move to the start position is detected.

It can be seen from this that, as shown in fig. 5, when the driving device 2 drives the cutter 11 to move toward the direction of the start position, the current detection module 30 can also detect the current value of the driving device 2 and upload the detected current value to the main control module 3, and once the current detection module 30 detects that the current value is greater than or equal to the preset value, it is indicated that the cutter 11 is blocked in the process of moving toward the start position, so that the current value of the driving device 2 rises rapidly and exceeds the preset value, and at this time, it can be determined that the cutter 11 is blocked secondarily.

Example two

A second embodiment of the present invention relates to a cutter resetting method for resetting a cutter of a soft towel box, as shown in fig. 6 and 7, comprising the steps of:

step 108, controlling the driving device 2 of the soft towel box according to the received reset instruction, so that the driving device 2 drives the cutter 11 to move towards the preset position.

The cutter movement method as described in the first embodiment is performed.

Specifically, in the present embodiment, the driving device 2 is configured to drive the cutter blade 11 to perform linear motion along the towel outlet side 91, and in order to satisfy such a motion mode of the cutter blade 11, the cutter blade 11 may employ a circular blade mechanism, as shown in fig. 12 and 13, and in order to drive the cutter blade 11 to perform linear motion along the towel outlet side 91, as shown in fig. 11, 14 and 15, the driving device 2 includes: the motor 21, the driving gear 22, the first synchronizing wheel 23, the second synchronizing wheel 24 and the synchronous belt 25. The motor 21 is electrically connected with the main control module 3, so that the motor 21 can directly control the main shaft of the motor 21 to rotate forward or reversely, in addition, as shown in fig. 11, the driving gear 22 is coaxially connected with the main shaft of the motor 21, and the first synchronous wheel 23 and the second synchronous wheel 24 are opposite to each other along a preset linear direction, in addition, the synchronous belt 25 is respectively meshed with the driving gear 22, the first synchronous wheel 23 and the second synchronous wheel 24, in practical application, as shown in fig. 12 and 13, the cutter 11 can be supported by adopting the support 13, and meanwhile, the support 13 can be arranged between the first synchronous wheel 23 and the second synchronous wheel 24 and fixedly connected with the synchronous belt 25, so that when the motor 21 drives the driving gear 22 to rotate, the driving gear 22 can synchronously drive the synchronous belt 25 by means of meshing with the synchronous belt 25, and the first synchronous wheel 23 and the second synchronous wheel 24 can rotate under the transmission of the synchronous belt 25, thereby realizing the linear movement of the support 13 between the first synchronous wheel 23 and the second synchronous wheel 24, so as to complete the cutter 11. Also, in some embodiments, as shown in fig. 12 and 13, the cutter blade 11 may be rotatably connected to the bracket 13, so that the cutter blade 11 may be rotated by friction with the flexible towel 100 when cutting the flexible towel 100. In addition, in order to avoid the slipping phenomenon between the synchronous belt 25 and the bracket 13 during the transmission, as shown in fig. 12, the bracket 13 is provided with a tooth row 131 capable of meshing with the synchronous belt 25, however, in practical application, the bracket 13 may be connected to the synchronous belt 25 in other forms, for example, a locking member such as a bolt may be used between the bracket 13 and the synchronous belt 25, and in the present embodiment, the connection manner between the bracket 13 and the synchronous belt 25 is not specifically limited. In order to further improve the transmission performance of the timing belt 25 when the drive bracket 13 moves, the drive device 2 further includes, as shown in fig. 11: the tensioning wheel 26, and this tensioning wheel 26 sets up between first synchronizing wheel 23 and second synchronizing wheel 24, and simultaneously, this tensioning wheel 26 still is walked around by hold-in range 25, can not only realize the direction to hold-in range 25 through tensioning wheel 26, can also improve the tensioning force of hold-in range 25 when the transmission to improve the transmission performance of hold-in range 25.

However, as a preferable scheme, in order to enable the driving device 2 to improve the cutting force of the cutter 11 on the soft towel 100 when driving the cutter 11 to move, further avoid the phenomenon that the cutter 11 is blocked when moving, as shown in fig. 12 and 13, a transmission assembly 12 may be further arranged on the bracket 13, the transmission assembly 12 may drive the cutter 11 to rotate, meanwhile, as shown in fig. 11, a rack 4 may be arranged along the moving direction of the cutter 11 corresponding to the transmission assembly 12, and the transmission assembly 12 is further meshed with the rack 4 for transmission, so that the driving device 2 can drive the cutter 11 to actively rotate through the meshing of the transmission assembly 12 and the rack 4 in the process of driving the cutter 11 by means of the bracket 13, thereby further improving the cutting force of the cutter 11 when cutting the soft towel 100, and enabling the soft towel 100 to be cut more easily.

Specifically, as shown in connection with fig. 12 and 13, the transmission assembly 12 includes: a first drive shaft 121, a drive gear 122, a second drive shaft 123, a first driven gear 124, and a second driven gear 125. The first transmission shaft 121 is rotatably disposed on the bracket 13, and the cutter 1 and the driving gear 122 are coaxially connected with the first transmission shaft 121 along a preset axis direction, and when the cutter 11 and the driving gear 122 are mounted with the first transmission shaft 121, the driving gear 122 can be located on any side of the cutter 11 along the preset axis direction. In addition, it should be noted that, as shown in fig. 12 and 13, the second transmission shaft 123 may be mounted in the same manner as the first transmission shaft 121, that is, the second transmission shaft 123 may be rotatably provided on the bracket 13 as well, and the second transmission shaft 123 may be provided parallel to the first transmission shaft 121, and further, the first driven gear 124 and the second driven gear 125 are coaxially connected to the second transmission shaft 123, while the second driven gear 125 is engaged with the driving gear 122 and the first driven gear 124 is engaged with the rack 4. Therefore, in practical use, when the driving device 2 is driving the cutter 11 to perform linear motion by means of the bracket 13, as shown in fig. 11, the first driven gear 124 can rotate by means of engagement with the rack 4, and when the first driven gear 124 is rotating, the second driven gear 125 can be driven by the second transmission shaft 123 to perform follow rotation, and when the second driven gear 125 is rotating, the fork can further drive the first transmission shaft 121 to rotate by means of engagement with the driving gear 122, thereby enabling the cutter 11 connected with the first transmission shaft 121 to perform active rotation.

In addition, as can be seen from the foregoing, since the cutter blade 11 and the transmission assembly 12 are disposed on the bracket 13, the cutter blade 11, the transmission assembly 12 and the bracket 13 can form the whole cutter device 1 capable of rectilinear motion along the flat towel side 91, as shown in fig. 12 and 13.

In addition, in order to enable the cutter 11 to move along the preset linear direction, the position of the cutter 11 may be detected, so as to avoid the cutter 11 from exceeding the stroke in the process of linear movement, as shown in fig. 14 and 15, the soft towel box of the present embodiment further includes: a first detection module 5 and a second detection module 6. In addition, the first detection module 5 and the second detection module 6 are arranged opposite to each other along the cutting path of the cutter 11, that is, the first detection module 5 is arranged at the start position of the cutting path of the cutter 11, the second detection module 6 is arranged at the end position of the cutting path of the cutter 11, and the first detection module 5 and the second detection module 6 are electrically connected with the main control module 3.

In practical application, as shown in fig. 14 and 15, the first detection module 5 and the second detection module 6 are both used for detecting the position of the cutter 11, and when the cutter 11 is detected by the first detection module 5, it is indicated that the cutter 11 at this time has moved to the start position, and at this time, the first electric signal may be output to the main control module 3 by the first detection module 5. When the second detection module 6 detects the cutter 11, it indicates that the cutter 11 has moved to the end position, and the second detection module 6 outputs a second electrical signal to the main control module 3, and the main control module 3 may turn off the motor 21 of the driving device 2 when receiving the first electrical signal or the second electrical signal, so that the cutter 11 may stay at the start position or the end position. Note that, in the present embodiment, the first detection module 5 and the second detection module 6 may be hall elements, and of course, in practical application, other detection elements, such as a proximity switch, a photoelectric sensor, etc., may be used for the first detection module 5 and the second detection module 6, but in the present embodiment, the types of the first detection module 5 and the second detection module 6 are not specifically limited.

In order to effectively determine whether the cutter 11 is blocked during the movement of the cutter 11, as shown in fig. 14, the soft towel box of the present embodiment further includes: the timing module 20 is electrically connected with the main control module 3, and when the timing module 20 is used, the movement duration of the cutter 11 can be timed. For example, when the cutter 11 moves to the start position, the timing module 20 may count the movement time of the cutter 11 and upload the counted time to the main control module 3, so when the time obtained by the main control module 3 is longer than or equal to the preset time, it is indicated that the main control module 3 does not receive the first electrical signal output by the first detection module 5 within the preset time, that is, the first detection module 5 does not detect the cutter 11, and at this time, the main control module 3 determines that the cutter 11 is blocked. Similarly, when the cutter 11 moves towards the end position, the timing module 20 can also count the movement time of the cutter 11 and upload the counted time to the main control module 3, so that when the time length obtained by the main control module 3 is longer than or equal to the preset time length, it is indicated that the main control module 3 does not receive the second electrical signal output by the second detection module 6 within the preset time length, that is, the second detection module 5 does not detect the cutter 11, and at this time, the main control module 3 determines that the cutter 11 is blocked.

As an alternative, in order to effectively determine whether the cutter 11 is blocked during the movement of the cutter 11, as shown in fig. 15, a current detection module 30, such as a current sensor, electrically connected to the main control module 3 may be further disposed in the towel box, and when the towel box is applied, the current value of the driving device 2 may be detected by the current detection module 30. For example, when the cutter 11 moves to the start position or to the end position, the current detection module 30 may detect the current value of the driving device 2 and upload the detected current value to the main control module 3, so when the current value obtained by the main control module 3 is greater than or equal to the preset value, it is indicated that the cutter 11 is subjected to a larger resistance in the process of moving to the start position, and at this time, the main control module 3 determines that the cutter 11 is blocked.

In addition, it should be noted that, in the present embodiment, the cutter blade 11 is only illustrated as an example along the direction of the towel outlet side 91, however, in practical application, the cutter blade 11 may also move along the direction perpendicular to the towel outlet side 91, that is, the cutter blade 11 cuts the flexible towel 100 in a form similar to a knife blade, and of course, when the cutter blade 11 moves along the direction perpendicular to the towel outlet side 91, the manner of determining that the cutter blade 2 is blocked is also applicable in the present embodiment, and will not be described in detail.

As can be seen from the foregoing, this embodiment is an example of a soft towel box corresponding to the first embodiment, and can be implemented in cooperation with the first embodiment. The related technical details mentioned in the first embodiment are still valid in this embodiment, and in order to reduce repetition, a detailed description is omitted here. Accordingly, the related art details mentioned in the present embodiment can also be applied to the first embodiment.

It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific embodiments in which the invention is practiced and that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
