[0026] To make the above objects, features, and advantages of the present application more apparent and understandable, the following provides a detailed description of the specific embodiments of the present application in conjunction with the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

These are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application.

[0028] In addition, if terms such as "first" and "second" appear, these terms are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0029] In the present application, unless otherwise clearly specified and limited, if terms such as "mounted", "connected", "connected to", "fixed", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0030] In this application, unless otherwise clearly defined and limited, if there is a description such as a first feature being "on" or "under" a second feature, its meaning can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.

[0031] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0032] In some embodiments, please refer to Figure 1 and Figure 2 , this application provides a cutting mechanism 100, and the cutting mechanism 100 includes: a transfer component 10, a cutter component 20 and a driving structure 30. The transfer component 10 includes a winding member 11 that can rotate around its own axis 111, and the winding member 11 is used to abut against the roller brush 200 to transfer the winding on the roller brush 200 to the winding member 11. The cutter component 20 is located on one side of the winding member 11, and the driving structure 30 is used to drive at least one of the cutter component 20 and the winding member 11 to move so that the cutter component 20 and the winding member 11 are in contact with each other.

[0033] For the above-mentioned cutting mechanism 100, when cleaning the winding, by using the abutment of the winding member 11 on the roller brush 200 and the rotation of the winding member 11 around its own axis 111, the winding wound on the roller brush 200 is transferred to the winding member 11 to achieve the cleaning of the roller brush 200. After the transfer, control at least one of the winding member 11 and the cutter component 20 to move so that the two are in contact, and use the cutter component 20 to cut the winding on the winding member 11 so that it cannot continue to wind on the winding member 11. In this way, by using the cutting mechanism 100 of this application, the winding on the roller brush 200 can be effectively removed, improving the cleaning effect; at the same time, it is also beneficial to improve the user experience.

[0034] It should be noted that when transferring the winding, please refer to Figure 6, while the winding member 11 abuts against the rotary brush 200 to form an interference and rotates around its own axis 111, the winding is transferred from the rotary brush 200 to its own structure by friction. To ensure that the circumferential winding on the rotary brush 200 can be transferred to the winding member 11, the rotary brush 200 can be in a rotating state when transferring the winding. Among them, the rotation direction of the winding member 11 and the rotation direction of the rotary brush 200 may not be the same or may be the same. When the rotation structure of the winding member 11 is the same as the rotation direction of the rotary brush 200, for example: both are clockwise rotation or counterclockwise rotation, the relative friction between the winding member 11 and the rotary brush 200 will be greater, increasing the transfer force and improving the cleaning effect on the rotary brush 200.

[0035] The rotation mode of the winding member 11 can be manually controlled or automatically controlled. When the rotation mode of the winding member 11 is automatic rotation, it can be driven by a motor or by a combination of a motor and a transmission component. Among them, the transmission component can be a gear, a belt, etc.

[0036] To improve the winding performance of the winding member 11 for the winding, please refer to Figure 4 , the winding member 11 can include a shaft core 113 and a soft layer 114 coated outside the shaft core 113, such as silicone or other rubber materials, so that the winding can better adhere to the winding member 11. Among them, the shaft core 113 can be made of a material with a certain stiffness, such as: plastics such as polycarbonate and polyamide; or metal materials such as aluminum alloy and iron.

[0037] It should also be noted that after the transfer of the winding is completed, the driving structure 30 can drive the winding member 11 to move, or can drive the cutter assembly 20 to move. Of course, it can also drive the winding member 11 and the cutter assembly 20 to move relative to each other, so that the cutter assembly 20 contacts the winding member 11, so that the cutter assembly 20 can cut off the winding on the winding member 11.

[0038] When the winding member 11 moves toward the cutter assembly 20 under the drive of the driving structure 30 and the rotation of the winding member 11 is automatically controlled, the driving structure 30 can move the winding member 11 and the related motor together, or can drive the winding member 11 alone. If the winding member 11 moves alone, a separable structure is designed between the motor and the winding member 11. For example: the friction wheel of the motor abuts against the winding member 11, and the winding member 11 is driven to rotate around its own axis 111 by friction; when the winding member 11 moves toward the cutter assembly 20, the winding member 11 is separated from the friction wheel.

[0039] In addition, the driving structure 30 can be a single driving device, such as an electric cylinder; or a combined structure of a driving device and a transmission device, such as: a combined structure of a motor, a gear and a rack, a combined structure of a motor, a lead screw and a slider, etc.

[0040] Furthermore, please refer toFigure 2 The transfer assembly 10 includes a mounting base 13, and the winding member 11 is rotatably connected to the mounting base 13. The driving structure 30 is used to drive at least one of the mounting base 13 and the cutter assembly 20 to move along the preset direction X, where the preset direction X intersects with the axial direction 111 of the winding member 11. In this way, the introduction of the mounting base 13 makes the winding member 11 stably installed, so as to ensure its smooth rotation, so as to better transfer the winding from the roller brush 200. At the same time, if the mounting base 13 is driven by the driving structure 30, it is convenient for the driving structure 30 to control the winding member 11, so that the transferred winding is effectively cut off.

[0041] It should be noted that, for the convenience of installing the winding member 11 on the mounting base 13, a rotating shaft 134 can be provided between the winding member 11 and the mounting base 13. For example, a rotating shaft 134 is provided on the mounting base 13, and a shaft hole 117 cooperating with the rotating shaft 134 is provided at one end of the winding member 11 along the axial direction 111.

[0042] Furthermore, please refer to Figure 3 and Figure 5 The mounting base 13 is provided with a first positioning portion 133, one end of the winding member 11 along the axial direction 111 is provided with a second positioning portion 115, and the side surface of the winding member 11 around the axial line 111 has a cutting portion 12. When the first positioning portion 133 cooperates with the second positioning portion 115, the cutting portion 12 is opposite to the cutting end of the cutter assembly 20 in the preset direction X. It can be seen from this that when the winding member 11 completes the transfer of the winding, the second positioning portion 115 can be fitted on the first positioning portion 133, so that the cutting portion 12 is aligned with the cutting end of the cutter assembly 20 in the preset direction X. At this time, only the driving structure 30 needs to be started, and the cutting end of the cutter assembly 20 can be cooperated with the cutting portion 12 to cut off the winding. Such a design greatly improves the cutting accuracy of the cutting mechanism 100 and enhances the cleaning effect of the winding.

[0043] Among the first positioning portion 133 and the second positioning portion 115, one of them can be a positioning protrusion, and the other is a positioning groove. Specifically, in some embodiments, the first positioning portion 133 is a positioning protrusion, and the second positioning portion 115 is a positioning groove.

[0044] It should be noted that the cutting portion 12 refers to a relatively sharp component on the winding member 11, and the cutting end of the cutter assembly 20 can be understood as the portion of the cutter assembly 20 that cooperates with the cutting portion 12 to cut off the winding, or can be understood as the end of the cutter assembly 20 with a cutting edge.

[0045] To prevent the winding from being cut off by the cutting part 12 during transfer, a groove 112 can be provided on the side surface of the winding member 11 around the outer circumference of the axis 111, and the cutting part 12 is embedded in the groove 112. In addition, to increase the cutting range, the cutting part 12 extends along the axis 111 direction on the winding member 11.

[0046] It should also be noted that the cutting part 12 and the cutting end of the cutter assembly 20 are opposite in the preset direction X, which should be understood as: in the preset direction X, the cutting part 12 and the cutting end of the cutter assembly 20 are kept aligned. At this time, whether the mounting seat 13 or the cutter assembly 20 is moved along the preset direction X, the cooperation between the cutting part 12 and the cutting end of the cutter assembly 20 can be ensured.

[0047] In some embodiments, please refer to Figure 3 and Figure 5 , one end of the winding member 11 along the axis 111 direction is also provided with a guiding surface 116, and the first positioning part 133 is configured as a positioning protrusion. The guiding surface 116 is used to abut against the first positioning part 133 to drive the winding member 11 to rotate, so that the first positioning part 133 cooperates with the second positioning part 115. It can be seen that when the winding member 11 stops winding the winding, if the first positioning part 133 abuts against the guiding surface 116. At this time, the guiding surface 116 cannot remain stationary under the abutment of the first positioning part 133. Coupled with the rotational inertia of the winding member 11 itself, it is easy to drive the winding member 11 to continue to rotate, so that the first positioning part 133 slides into the second positioning part 115 to realize the automatic positioning of the automatic winding member 11. Of course, when the winding member 11 stops winding the winding, the first positioning part 133 may also just abut against the second positioning part 115.

[0048] It can be known that the first positioning part 133 is configured as a positioning protrusion, and the second positioning part 115 is a positioning groove matching it. At the same time, in order to make the first positioning part 133 abutting against the guiding surface 116 slide into the second positioning part 115 more smoothly, the guiding surface 116 can be designed as an inclined surface or an arc-shaped convex surface, etc.

[0049] In addition, it should be noted that neither the cooperation between the first positioning part 133 and the second positioning part 115 nor the cooperation between the first positioning part 133 and the guiding surface 116 will cause the winding member 11 to be unable to rotate around the axis 111. For example: when transferring the winding, the output torque of the winding member 11 can be appropriately increased to overcome the cooperation force between the first positioning part 133 and the second positioning part 115 or the guiding surface 116.

[0050] Of course, for the convenience of the rotation of the winding member 11, the first positioning portion 133 can be designed as a positioning protrusion with an elastic function. For example, the first positioning portion 133 can be, but is not limited to, a rubber column, a plastic column, etc. When the first positioning portion 133 is an elastic positioning protrusion, the rotation of the winding member 11 can overcome the resistance of the elastic positioning protrusion and rotate, so that the winding objects on the roller brush 200, such as hair, etc., are transferred to the winding member 11.

[0051] Furthermore, please refer to Figure 3 and Figure 5 , the second positioning portion 115 and the cutting portion 12 both include a plurality of and are arranged in a one-to-one manner. All the second positioning portions 115 are distributed at intervals on the outer periphery of the axis 111. There is a guiding surface 116 between two adjacent second positioning portions 115. The middle part of each guiding surface 116 protrudes in an arc along the direction of the axis 111, that is, the middle part of the guiding surface 116 is higher, and the two sides close to the second positioning portion 115 are lower. Therefore, when the first positioning portion 133 abuts against the guiding surface 116, it will be gradually guided to the second positioning portion 115 under the action of the arc protrusion to achieve automatic positioning. When the first positioning portion 133 cooperates with one of the second positioning portions 115, one of the cutting portions 12 will be opposite to the cutting end of the cutter assembly 20 in the preset direction X. In this way, by introducing a plurality of second positioning portions 115 and cutting portions 12, no matter what angle the winding member 11 rotates to, it will be corrected to the cooperation between the first positioning portion 133 and one of the second positioning portions 115, so as to ensure that the cutting end of the cutter assembly 20 is aligned with one of the cutting portions 12, and further ensure that the winding object is accurately cut.

[0052] It should be noted that the one-to-one setting of the cutting portion 12 and the second positioning portion 115 should be understood as: when the first positioning portion 133 cooperates with different second positioning portions 115, there is always a cutting portion 12 that is opposite to the cutter assembly 20 in the preset direction X. Specifically, in some embodiments, all the cutting portions 12 are distributed at intervals on the outer periphery of the winding member 11 around the axis 111, and the positions of the intersection lines formed by each cutting portion 12 and the axis 111 on one end portion of the winding member 11 along the direction of the axis 111 can be the positions where the corresponding second positioning portions 115 are located.

[0053] Optionally, the number of the cutting portions 12 and the second positioning portions 115 is not limited to only Figure 3 and Figure 4 shown in the figure, and can also be other numbers. For example, the number of the cutting portions 12 and the second positioning portions 115 can be two, three, five or more. When the number of both the cutting portions 12 and the second positioning portions 115 is four, the four second positioning portions 115 are equally spaced on the outer periphery of the axis 111.

[0054] In addition, the number of the first positioning portions 133 may also be multiple. For example, all the first positioning portions 133 are circumferentially arranged on the mounting base 13 and are arranged in one-to-one correspondence with the second positioning portions 115.

[0055] In some embodiments, a tool groove 121 is provided on the cutting portion 12, and the cutter assembly 20 includes a blade 21. When the cutter assembly 20 is in contact with the winding member 11, the blade 21 is inserted into the tool groove 121. In this way, by introducing the tool groove 121, the feed amount of the blade 21 can be increased to ensure that the winding can be effectively cut off.

[0056] In some embodiments, please refer to Figure 1 , the transfer assembly 10 further includes a reset member 16. The driving structure 30 is drivingly connected to the mounting base 13 to bring the winding member 11 into contact with the cutter assembly 20 and out of contact with the rotary brush 200, and the reset member 16 is used to urge the winding member 11 to abut against the rotary brush 200. It can be seen therefrom that after the winding member 11 completes the transfer of the winding, the driving structure 30 drives the mounting base 13 to move, driving the winding member 11 to disengage from the rotary brush 200 and come into contact with the cutter assembly 20 to complete the cutting operation of the winding. After the cutting operation is completed, the driving structure 30 stops working. At this time, the reset member 16 drives the winding member 11 to move so that it abuts against the rotary brush 200 again.

[0057] It should be noted that the reset member 16 refers to a structure that can urge the winding member 11 to return to the initial position and abut against the rotary brush 200 when the mounting base 13 is not affected by the driving structure 30. The reset member 16 can have various designs. For example, it can be a combined structure of a motor and a transmission component, or an elastic member, such as a spring, elastic rubber, elastic metal sheet, etc. Among them, the reset member 16 can act directly on the winding member 11 or indirectly act on the winding through the mounting base 13.

[0058] Specifically, please refer to Figure 2 , the reset member 16 is a spring. When the driving structure 30 is in a non-working state, the winding member 11 returns to abut against the roller under the action of the elastic force.

[0059] In addition, for the convenience of user operation, a button connected to the driving structure 30 can be provided. When it is necessary to cut off the winding transferred to the winding member 11, press the button to start the driving structure 30. The driving structure 30 drives the winding member 11 to approach the cutter assembly 20, so that the cutting portion 12 and the cutter assembly 20 act on each other to cut off the winding. The cut winding is very short and cannot be wound on the winding member 11 anymore. Therefore, the cut winding will fall off and is finally sucked into the sewage tank by suction. After cutting the winding, release the button, the driving structure 30 stops working, and the winding member 11 returns to the initial position under the action of the reset member 16.

[0060] When it is necessary to cut the winding (usually press the button once every 1 - 2 minutes to start the cutting operation, and adjust the winding cutting time appropriately according to the amount of winding at the position to be cleaned. For more winding, press the button more frequently; for less winding, the number of times of pressing the button to cut the winding can be reduced), press the button. At this time, the driving structure 30 is started, driving the winding member 11, and the cutting portion 12 on the winding member 11 cooperates with the cutter assembly 20 to form the function of cutting the winding (for example: the two blades 21 cooperate to form a function similar to scissors).

[0061] Further, please refer to Figure 2 , the transfer assembly 10 further includes a sliding seat 14, and a sliding groove 141 extending along a preset direction X is provided on the sliding seat 14. At least part of the mounting seat 13 is slidably disposed in the sliding groove 141, and the reset member 16 is connected between the groove wall of the sliding groove 141 and the mounting seat 13. In this way, at least part of the mounting seat 13 is slidably disposed in the sliding groove 141, making the movement of the mounting seat 13 smoother, ensuring that the cutter assembly 20 is in accurate contact with the winding member 11, which is beneficial to improving the cutting accuracy of the winding.

[0062] It should be noted that when the reset member 16 is a spring, a positioning sleeve 135 can be provided on the mounting seat 13. One end of the spring is inserted into the positioning sleeve 135, and the other end abuts against the groove wall of the sliding groove 141. At the same time, when the winding member 11 contacts the cutter assembly 20, the spring can be in a compressed state or a stretched state. When the mounting seat 13 is not affected by the driving structure 30, the spring can drive the winding member 11 to return to the initial position with elastic thrust or elastic tension.

[0063] To further improve the structural stability of the cutting mechanism 100, please refer to Figure 5 , the mounting seat 13 can include two spaced-apart mounting portions 131 and a connecting portion 132 connecting the two mounting seats 13. The opposite ends of the winding member 11 are respectively rotatably connected to the two mounting portions 131, and the driving structure 30 is drivingly connected to the connecting portion 132. At this time, there can be two sliding seats 14, and the two side surfaces of the two sliding seats 14 facing each other both have sliding grooves 141. Please refer to Figure 1 . The two mounting portions 131 are respectively disposed corresponding to the two sliding seats 14. In this way, both sides of the mounting seat 13 are guided, improving the smoothness of the movement.

[0064] In addition, to facilitate the contact between the winding member 11 and the cutter assembly 20, please refer to Figure 1 , the cutter assembly 20 can be located between the winding member 11 and the connecting portion 132. At the same time, the transfer assembly 10 further includes a base 15, the two sliding seats 14 are respectively and spacedly fixed on the base 15, and the cutter assembly 20 includes a blade 21 and a support member 22, and the blade 21 is mounted on the base 15 through the support member 22.

[0065] In some embodiments, the transfer assembly 10 further includes a first driver. When the cutting mechanism 100 is in the winding mode, the first driver cooperates with the winding member 11 to drive the winding member 11 to rotate; when the cutting mechanism 100 is in the cutting mode, the first driver is disengaged from the winding member 11. It can be seen from this that the cutting mechanism 100 has at least two modes. First, the winding mode. Please refer to Figure 6 , in this mode, the winding on the rotary brush 200 can be transferred out; second, the cutting mode. Please refer to Figure 7 , in this mode, the transferred winding can be cut. When in the winding mode, the winding member 11 cooperates with the first driver and rotates around its own axis 111 under the action of the first driver, improving the strength of winding the winding. When in the cutting mode, the winding member 11 can be disengaged from the first driver. At this time, the first driver does not move with the winding member 11. This not only helps to reduce the power output, but also avoids reserving a large space for the operation of the first driver. In this way, on the premise of energy saving, the structural design of the cutting mechanism 100 is more compact.

[0066] It should be noted that the first driver refers to a component that provides power for the rotation of the winding member 11, which can be a motor or the like. To facilitate the winding member 11 to return to stable cooperation with the first driver when it abuts against the rotary brush 200, a friction wheel can be provided on the output end of the first driver. When the winding member 11 abuts against the rotary brush 200, at least a part of the winding member 11 also abuts against the friction wheel at the same time.

[0067] In some embodiments, please refer to Figure 2 , the driving structure 30 includes a transmission member 33, a second driver 31, and an eccentric wheel 32 driven by the second driver 31. One end of the transmission member 33 is connected to the eccentric wheel 32, and the other end is in transmission cooperation with the cutter assembly 20 or the winding member 11. In this way, please refer to Figure 7 , when the cutting mechanism 100 is in the cutting mode, the second driver 31 is started to drive the eccentric wheel 32 to rotate, so that the eccentric wheel 32 pulls the winding member 11 or pushes the cutter assembly 20 through the transmission member 33, so that the two are in contact with each other to complete the cutting of the winding.

[0068] In some embodiments, a cleaning device includes a rotary brush 200 and a cutting mechanism 100 as described in any one of the above. When the cutting mechanism 100 is in the winding mode, the winding member 11 abuts against the rotary brush 200 and can transfer the winding on the rotary brush 200.

[0069] The above cleaning device adopts the above cutting mechanism 100, which can effectively remove the winding on the rotary brush 200 and improve the cleaning effect; at the same time, it is also beneficial to improve the user experience. Among them, the cleaning device can be, but is not limited to, a floor washer, a sweeper, a mopping machine, etc.

[0070] It should be noted that when the cleaning device is in normal operation, that is, when the rotary brush 200 rotates for cleaning, the winding member 11 can remain in contact with the rotary brush 200; it can also be not in contact with the rotary brush 200. When the cutting mechanism 100 is in the winding mode, the winding member 11 can move to contact with the rotary brush 200. Specifically, in some embodiments, when the cleaning device is in normal operation, the winding member 11 remains in contact with the rotary brush 200.

[0071] Further, please refer to Figure 8 , the winding member 11 is in contact with the rotary brush 200, and there is a contact deformation amount between them. The maximum value of the contact deformation amount is denoted as D, where 2.5 mm ≤ D ≤ 3.5 mm.

[0072] It can be seen from this that when the cleaning device is cleaning, a large amount of sewage will accumulate on the rotary brush 200. If the floor is to be washed and mopped clean, the sewage on the rotary brush 200 needs to be squeezed out. Thus, the winding member 11 is designed to be in contact with the rotary brush 200, and the sewage on the rotary brush 200 is squeezed down in a contact manner. The maximum value of the contact deformation amount between the winding member 11 and the rotary brush 200 is designed to be 2.5 mm to 3.5 mm. For example: the value of D can be, but is not limited to, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, 3.0 mm, 3.1 mm, 3.2 mm, 3.3 mm, 3.4 mm, 3.5 mm, etc.

[0073] If the contact deformation amount is too small, the sewage cannot be squeezed out cleanly, and the floor cannot be washed and mopped clean; if the contact deformation amount is too large, then the resistance of the winding member 11 to the rotary brush 200 is too large. At the same time, the winding member 11 is designed to have a contact deformation amount of 2.5 mm to 3.5 mm with the rotary brush 200, which can transfer the hair wound on the rotary brush 200 to the winding member 11, and there will be no hair wound on the rotary brush 200.

[0074] Among them, it should be noted that the contact deformation amount between the winding member 11 and the rotary brush 200 can also be understood as: the interference amount between the winding member 11 and the rotary brush 200, that is, the interference formed by the mutual pressing of the two. To facilitate measuring the maximum value of the contact deformation amount between the winding member 11 and the rotary brush 200, reference can be made to Figure 8 the distance represented by D in for measurement. Of course, it is also possible to first measure the center distance between the winding member 11 and the rotary brush 200, and then subtract the center distance from the sum of the radii of the winding member 11 and the rotary brush 200. The obtained value can be the maximum value of the contact deformation amount.

[0075] In addition, to facilitate the collection of sewage or the cut winding objects, a sewage suction port can be provided behind the rotary brush 200, and the cut winding objects or the squeezed sewage are sucked into the sewage tank through the sewage suction port.

[0076] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0077] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
