[0058] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0059] The following describes a cutting blade 200 for a cleaning device according to an embodiment of the present invention with reference to the accompanying drawings.

[0060] like Figures 1-6 As shown, the cutting blade 200 of the cleaning device according to the embodiment of the present invention includes a blade body 201 and a cutting body 202 .

[0061] The blade body 201 extends along a first direction, and has a connecting portion 203 at one end of the blade body 201 along the first direction. The cutting blade 200 can be set at a specified position using the connecting portion 203. The cutting body 202 is located on at least one side of the blade body 201 and includes a blade portion 2021 and a protrusion 2022. The protrusion 2022 is located at the other end of the blade body 201 along the first direction and protrudes from the blade portion 2021. When the cutting blade 200 is operated, the protrusion 2022 can hook the slender fiber material so that the blade portion 2021 can smoothly cut the fiber material.

[0062] Specifically, fibrous materials are easily entangled on objects, and the cutting blade 200 with only the blade portion 2021 is not easy to cut the fibrous materials when cutting the fibrous materials, and is easy to scratch the objects. The present invention provides a protrusion 2022. When it is necessary to cut the fibrous materials, the protrusion 2022 is first used to hook the fibrous materials, and then the fibrous materials are pulled away from the object to facilitate the blade portion 2021 to cut the fibrous materials, and at the same time, it can avoid the blade portion 2021 from contacting the object, thereby preventing the blade portion 2021 from scratching the object.

[0063] For example, hair and other fibrous garbage are easily entangled on the roller brush 62 of the cleaning device. When the blade part 2021 is operated to cut the fibrous garbage on the roller brush 62, the protrusion 2022 can hook the hair and other fibrous garbage on the roller brush 62 to pull the hair and other fibrous garbage away from the roller brush 62, so that the blade part 2021 can cut off the hair and other fibrous garbage, and cut the hair and other fibrous garbage into shredded garbage, so that it can no longer continue to entangle on the roller brush 62, thereby achieving the cleaning of the roller brush 62.

[0064] According to the cutting blade 200 of the cleaning device according to an embodiment of the present invention, a protrusion 2022 is provided, which is used to hook hair and other fibrous materials and pull the hair and other fibrous materials away from the roller brush 62. This makes it easier for the blade portion 2021 to cut hair and other fibrous garbage, thereby cutting hair and other fibrous garbage into shredded garbage so that it cannot continue to be entangled on the roller brush 62.

[0065] The following describes a cutting blade 200 for a cleaning device according to a specific embodiment of the present invention with reference to the accompanying drawings.

[0066] In some specific embodiments of the present invention, Figures 1-6 As shown, the cutting blade 200 of the cleaning device includes a blade body 201 and a cutting body 202 .

[0067] In some embodiments of the present invention, Figure 2 As shown, one end of the blade portion 2021 is connected to the protrusion 2022. Thus, after the protrusion 2022 hooks onto the fiber, the blade portion 2021 can promptly cut the fiber. The other end of the blade portion 2021 extends away from the protrusion 2022 and gradually deviates from the centerline of the blade body 201 extending along the first direction. This increases the area of ​​the blade portion 2021, thereby increasing the contact area between the blade portion 2021 and the fiber, allowing the blade portion 2021 to smoothly cut the fiber.

[0068] In addition, when the protrusion 2022 hooks the fiber material and causes the fiber material to slide along the first direction toward the direction away from the protrusion 2022, since the blade portion 2021 extends along the direction away from the protrusion 2022 and gradually deviates from the center line of the blade body 201 extending along the first direction, when the fiber material slides, the distance between the fiber material and the blade portion 2021 gradually decreases or the force between the fiber material and the blade portion 2021 gradually increases, so that the blade portion 2021 can smoothly cut the fiber material.

[0069] like Figure 2As shown, in this embodiment, the first direction extends in the up-down direction, the blade portion 2021 and the protrusion 2022 are located on the right side of the center line of the blade body 201 extending along the first direction, the protrusion 2022 is located on the lower side of the blade portion 2021, and the blade portion 2021 extends obliquely from bottom to top toward the right. When the cutting blade 200 swings to the right, the protrusion 2022 can hook on fibers such as hair and guide the fibers to slide upward along the first direction. At this time, the blade portion 2021 contacts the fibers and when the cutting blade 200 continues to swing to the right, the gap between the blade portion 2021 and the fibers becomes smaller and the force becomes greater, so that the blade portion 2021 can smoothly cut through the fibers.

[0070] It should be explained here that when the cutting blade 200 swings, the blade body 201 does not always extend in the up-down direction. For example, when the cutting blade 200 swings, the blade body 201 may extend in an inclined direction. The first direction defined here as extending in the up-down direction means extending in the up-down direction. Figure 2 In this state, the blade body 201 extends in the up-down direction.

[0071] In some examples, such as Figure 2 As shown, the protrusion 2022 extends in the left-right direction, and the blade portion 2021 extends obliquely from bottom to top toward the right. An acute angle is formed between the blade portion 2021 and the protrusion 2022. After the protrusion 2022 hooks the fiber, the protrusion 2022 guides the fiber toward the angle between the blade portion 2021 and the protrusion 2022, and the fiber is cut by the blade portion 2021. The acute angle between the blade portion 2021 and the protrusion 2022 facilitates limiting the position of the fiber on the blade portion 2021, allowing the blade portion 2021 to smoothly cut the fiber, preventing the fiber from slipping off the blade portion 2021 and preventing the fiber from being entangled on the cutting blade 200.

[0072] In some embodiments of the present invention, Figure 2 As shown, the blade portion 2021 and the protrusion 2022 are set at an angle, and the angle is greater than 0° and less than 180°. In this way, when the protrusion 2022 hooks the fiber, the fiber can be guided to the blade portion 2021, and then the blade portion 2021 is used to cut the fiber.

[0073] In some optional embodiments of the present invention, the angle between the blade portion 2021 and the protrusion 2022 is less than or equal to 90°. When the protrusion 2022 hooks the fiber material and guides the fiber material to the blade portion 2021, the fiber material can be confined between the blade portion 2021 and the protrusion 2022, so that the blade portion 2021 can smoothly cut the fiber material, preventing the fiber material from slipping out of the blade portion 2021 and preventing the fiber material from being entangled on the cutting blade 200.

[0074] In some embodiments, the included angle between the blade portion 2021 and the protruding portion 2022 can be 20°, 30°, 45° or 60°, which is not limited here.

[0075] In some embodiments of the present application, as shown in Figure 4 , Figure 5 The number of cutting bodies 202 is two, and the two cutting bodies 202 are located on opposite sides of the blade body 201, so that both sides of the cutting body 202 can be used to cut objects when the cutting body 202 reciprocates, thereby improving the cutting efficiency of the cutting blade 200.

[0076] As shown in Figure 5 In this embodiment, the two cutting bodies 202 are respectively arranged on the left and right sides of the blade body 201, and the connecting portion 203 of the blade body 201 is swingably arranged at a specified position. When the cutting blade 200 swings to the right, the cutting body 202 on the right side of the blade body 201 can cut the object, and when the cutting blade 200 swings to the left, the cutting body 202 on the left side of the blade body 201 can cut the object. In this way, when the cutting blade 200 reciprocates, the movement of the cutting blade 200 will not be wasted, thereby facilitating the improvement of the cutting efficiency of the cutting blade 200.

[0077] In some optional embodiments of the present application, the blade portion 2021 of the two cutting bodies 202 extends obliquely towards the connecting portion 203 and away from each other, so that the size of the end of the cutting blade 200 away from the connecting portion 203 is smaller, thereby facilitating the end of the cutting blade 200 away from the connecting portion 203 to extend into a narrow space, thereby adapting to the environment of a narrow space.

[0078] In addition, the oblique extension of the blade portion 2021 of the two cutting bodies 202 facilitates the increase of the area of the blade portion 2021 on the two cutting bodies 202, so that the blade portion 2021 can smoothly cut the fiber object.

[0079] In some embodiments of the present application, the end of the protruding portion 2022 away from the blade portion 2021 is formed as a rounded corner, so that when the protruding portion 2022 hooks and wraps the fiber object on the object, the protruding portion 2022 can avoid scratching the object.

[0080] In some examples, the roller brush 62 of the cleaning device includes a rotating rod 621 and a plurality of bristles 622, and the plurality of bristles 622 are arranged on the peripheral wall of the rotating rod 621. The cutting blade 200 is used to cut fibrous garbage such as hair wrapped around the roller brush 62 of the cleaning device. When the cutting blade 200 swings, the protrusion 2022 can hook the fibrous garbage on the roller brush 62, so that the end of the protrusion 2022 away from the blade portion 2021 is formed into a rounded corner. When the protrusion 2022 hooks the fibrous garbage on the roller brush 62, even if the protrusion 2022 contacts the rotating rod 621, the protrusion 2022 will not scratch the rotating rod 621.

[0081] By making the distance between the protrusion 2022 and the rotating rod 621 closer or making the protrusion 2022 contact with the rotating rod 621 when swinging, the protrusion 2022 can hook the hair and other fibrous garbage tightly wrapped around the roller brush 62, so as to fully cut off the hair and other fibrous garbage wrapped around the roller brush 62, so that the fibrous garbage will not continue to wrap around the roller brush 62 due to its shortened length, thereby achieving the cleaning of the roller brush 62.

[0082] The following describes a cutting assembly 1 according to an embodiment of the present invention. The cutting assembly 1 according to the embodiment of the present invention comprises a swingable movable blade, which is the cutting blade 200 according to the above-mentioned embodiment of the present invention.

[0083] According to the cutting assembly 1 of the embodiment of the present invention, by utilizing the cutting blade 200 of the cleaning device according to the above embodiment of the present invention, by providing the protrusion 2022, the protrusion 2022 is used to hook the hair and other fibrous materials, and the hair and other fibrous materials can be pulled away from the roller brush 62, so that it is convenient for the blade portion 2021 to cut the hair and other fibrous garbage, so as to cut the hair and other fibrous garbage into shredded garbage, so that the hair and other fibrous garbage can no longer be entangled on the roller brush 62.

[0084] In some embodiments of the present invention, the cutting assembly 1 further includes a housing 10, at least one movable blade mechanism 20, and a driving member 30. The housing 10 defines a receiving chamber 11 having an opening 111. The movable blade mechanism 20 is disposed in the housing 10 and includes a movable blade. The driving member 30 is configured to drive the movable blade to swing. The movable blade switches between a first state and a second state. When the movable blade is in the first state, the movable blade is stored in the receiving chamber 11. At this time, the cleaning device can be used normally to clean the surface to be cleaned, preventing the movable blade from affecting the rolling of the roller brush 62 in the cleaning device and preventing the movable blade from scratching the user when the user is cleaning the cleaning device. This improves the safety of the cleaning device.

[0085] When the movable blade is in the second state, the protrusion 2022 and the blade portion 2021 at least partially extend from the opening 111 to the outside of the accommodating cavity 11. At this time, when the driving member 30 drives the movable blade to swing, the protrusion 2022 on the movable blade can hook the hair and other fiber materials wrapped around the object, and pull the fiber materials away from the object, making it convenient for the blade portion 2021 to cut the fiber materials, and at the same time avoiding the blade portion 2021 from contacting the object, preventing the blade portion 2021 from scratching the object.

[0086] In some embodiments, the cutting assembly 1 is used to clean hair and other fibrous debris on the roller brush 62. The cutting assembly 1 cuts the hair and other fibrous debris on the roller brush 62 so that the hair and other fibrous debris cannot continue to entangle with the roller brush 62, thereby cleaning the roller brush 62. When the driving member 30 drives the movable blade to swing, the protrusion 2022 can hook the hair and other fibrous debris entangled with the roller brush 62, thereby pulling the hair and other fibrous debris away from the roller brush 62. This facilitates the blade portion 2021 to cut the hair and other fibrous debris, thereby cutting the hair and other fibrous debris into shredded garbage, preventing the hair and other fibrous debris from continuing to entangle with the roller brush 62, thereby cleaning the roller brush 62.

[0087] In some optional embodiments of the present invention, Figure 11 、 Figure 12 The movable blade mechanism 20 further includes a swinging member 22 , which is swingably disposed on the housing 10 and movably cooperates with the movable blade. The driving member 30 drives the swinging member 22 to swing, thereby driving the movable blade to swing through the swinging member 22 .

[0088] In particular, compared to having the driving member 30 directly drive the movable blade to swing, having the driving member 30 drive the movable blade to swing through the swinging member 22 facilitates realizing that one driving member 30 drives multiple movable blades to swing simultaneously. For example, the cutting assembly 1 includes a swinging member 22 and multiple movable blades, and the swinging member 22 is movably matched with the multiple movable blades. When the driving member 30 drives the swinging member 22 to swing, the swinging member 22 can drive the multiple movable blades to swing together; or the cutting assembly 1 includes multiple swinging members 22 and multiple movable blades, and the multiple swinging members 22 are linked to each other, and the swinging members 22 are movably matched with the movable blades one by one. When the driving member 30 drives one of the swinging members 22 to swing, the multiple swinging members 22 can swing together, thereby driving the multiple movable blades to swing together.

[0089] In some specific embodiments of the present invention, the first end of the swinging member 22 is swingably provided on the housing 10, and the second end of the swinging member 22 is movably cooperated with the moving blade, wherein the first end is the swinging center of the swinging member 22, and the second end is longer than the first end. When the driving member 30 drives the swinging member 22 to swing, the swinging path of the second end of the swinging member 22 is larger, and the second end of the swinging member 22 is used to drive the moving blade to move, so that the moving blade can swing at a larger angle, thereby making the moving blade sweep over a larger area during the swinging process.

[0090] The driving member 30 drives the movable blade to swing through the swinging member 22, which can amplify the rotation angle transmitted by the driving member 30 to the movable blade, causing the movable blade to swing at a larger angle, thereby causing the swinging member 22 to sweep over a larger area during the swinging process. Specifically, if the driving member 30 directly drives the movable blade to swing, then the swinging angle of the movable blade will be the same as the rotation angle of the driving member 30. The present invention enables the second end of the swinging member 22 to flexibly cooperate with the movable blade. Since the second end of the swinging member 22 has a larger swinging path, the second end of the swinging member 22 drives the movable blade to swing at a larger angle, thereby increasing the range that the movable blade can cut, thereby improving the cutting efficiency of the cutting assembly 1.

[0091] like Figure 11 、 Figure 14 As shown, one end of the movable blade is rotatably provided on the housing 10, and the other end is located on the side of the rotating center of the movable blade away from the first end of the swinging member 22. The first end of the swinging member 22 is opposite to the swinging center of the movable blade in the up and down directions and is spaced apart. When the driving member 30 drives the swinging member 22 to swing at an angle of α1, the swinging member 22 drives the movable blade to swing at an angle of α2, and α2 is greater than α1. When the rotation angle of the driving member 30 is the same, compared with the driving member 30 directly driving the movable blade to swing, the driving member 30 drives the movable blade to rotate at a larger angle through the swinging member 22, thereby increasing the swinging area of ​​the movable blade, increasing the range that the movable blade can cut, and improving the cutting efficiency of the cutting assembly 1.

[0092] In some optional embodiments of the present invention, Figure 11 、 Figure 12 As shown, the second end of the swinging member 22 and one of the movable blades have a mating protrusion 221, and the other has a mating groove 211. The mating protrusion 221 and the mating groove 211 are slidably engaged with each other, so that the swinging member 22 can smoothly drive the movable blade to swing, thereby preventing the swinging member 22 and the movable blade from getting stuck.

[0093] Specifically, the second end of the swinging member 22 swings around the first end of the swinging member 22, and the moving blade swings around one end of the moving blade. That is to say, the swinging centers of the swinging member 22 and the moving blade are not the same. Therefore, in the process of the swinging member 22 driving the moving blade to swing, the distance between the second end of the swinging member 22 and the swinging center of the moving blade will change, so that the second end of the swinging member 22 slides with the moving blade to adapt to the distance between the second end of the swinging member 22 and the swinging of the moving blade, so that the swinging member 22 can smoothly drive the moving blade to swing, avoiding the swinging member 22 and the moving blade from being stuck at a certain position.

[0094] like Figure 11 As shown, in this embodiment, a mating protrusion 221 is provided at the second end of the swinging member 22, and a mating groove 211 is provided on the movable blade, and the mating groove 211 extends along the length direction of the movable blade. When the swinging member 22 drives the movable blade to swing, the mating protrusion 221 slides in the mating groove 211 to adapt to the distance between the second end and the swing center of the movable blade, thereby enabling the swinging member 22 to smoothly drive the movable blade to swing.

[0095] In some embodiments, as Figure 15 、 Figure 16 As shown, a guide protrusion 223 is further provided at the second end of the swinging member 22. The guide protrusion 223 and the matching protrusion 221 are located on both sides of the thickness direction of the swinging member 22. A guide groove 14 is provided on the shell 10. The guide groove 14 is an arc-shaped groove. The guide protrusion 223 and the guide groove 14 are slidably matched to support the swinging of the swinging member 22, so as to improve the stability of the swinging of the swinging member 22.

[0096] In the embodiment where the movable blade mechanism 20 includes a plurality of swinging members 22 and a plurality of movable blades, a plurality of guide grooves 14 are provided on the housing 10 , and the plurality of guide grooves 14 can be interconnected.

[0097] In some specific embodiments of the present invention, Figure 11 、 Figure 12 As shown, the mating protrusion 221 or the mating groove 211 on the movable blade is eccentrically arranged relative to the swing center of the movable blade, so that the second end of the swing member 22 can drive the movable blade to swing around the swing center of the movable blade when swinging.

[0098] Specifically, the mating protrusion 221 or the mating groove 211 on the moving blade is eccentrically arranged relative to the swing center of the moving blade, so that there is a certain distance between the second end of the swinging member 22 and the rotation center of the moving blade, so that the swinging member 22 can apply torque to the moving blade through the mating protrusion 221 or the mating groove 211 on the moving blade, so that the swinging member 22 can drive the moving blade to swing smoothly.

[0099] When the swinging member 22 swings along the same path length, the closer the distance between the mating protrusion 221 or the mating groove 211 on the movable blade and the swing center of the movable blade is, the greater the angle at which the swinging member 22 drives the movable blade to swing, but the smaller the torque applied by the swinging member 22 to the movable blade. Therefore, the distance between the mating protrusion 221 or the mating groove 211 on the movable blade and the swing center of the movable blade should not be too large or too small. For example, the mating protrusion 221 or the mating groove 211 on the movable blade is located in the middle of the movable blade so that the swinging member 22 can drive the movable blade to swing through a larger angle and apply sufficient torque to the movable blade to drive the movable blade to swing.

[0100] In some optional embodiments of the present invention, Figure 11 As shown, the movable blade is rotatably connected to the housing 10 via the first rotating shaft 51. The swinging member 22 has a first avoidance groove 222 for avoiding the first rotating shaft 51 to prevent the first rotating shaft 51 from interfering with the swinging of the swinging member 22. The first avoidance groove 222 is an arc-shaped groove to adapt to the swinging of the swinging member 22 and avoid the groove size opened on the swinging member 22 being too large, so as to ensure the structural strength of the swinging member 22.

[0101] The first avoidance groove 222 is located between the first end and the second end of the swinging member 22, so that the second end of the swinging member 22 can drive the movable blade to swing at a larger angle, so that the movable blade sweeps over a larger area.

[0102] Specifically, the second end of the swinging member 22 is movably engaged with a portion of the movable blade located on the first rotating shaft 51 away from the first avoidance groove 222, such as Figure 11 As shown, the arrangement is such that the swinging member 22 and the moving blade have the same swinging direction. For example, when the swinging member 22 swings to the left, the swinging member 22 drives the moving blade to swing to the left, and when the swinging member 22 swings to the right, the swinging member 22 drives the moving blade to swing to the right. In this way, on the one hand, the swinging member 22 can drive the moving blade to swing at a larger angle when swinging. On the other hand, it is convenient to arrange the swinging member 22 and the moving blade compactly, so as to reduce the space occupied by the swinging member 22 and the moving blade in the accommodating cavity 11.

[0103] like Figure 1 As shown, the connecting portion 203 on the movable blade is a through hole, and the first rotating shaft 51 passes through the connecting portion 203 and is connected to the movable blade, so that the movable blade is swingably arranged on the housing 10.

[0104] In some embodiments, as Figure 11As shown, the shell 10 includes a supporting plate, which is arranged in the accommodating cavity 11, and the swinging member 22 and the movable blade are arranged on the same side of the supporting plate. The swinging member 22 is swingably arranged on the supporting plate, and the movable blade is rotatably connected to the supporting plate through a first rotating shaft 51. The movable blade is located on the side of the swinging member 22 away from the supporting plate. In order to set the first rotating shaft 51 on the supporting plate, the first rotating shaft 51 needs to pass through the swinging member 22 and cooperate with the supporting plate. Therefore, a first avoidance groove 222 is provided on the swinging member 22 to avoid the first rotating shaft 51 interfering with the swinging of the swinging member 22.

[0105] In some other optional embodiments of the present invention, the shell 10 includes a supporting plate, which is arranged in the accommodating cavity 11, and the swinging member 22 and the movable blade are arranged on different sides of the supporting plate. The swinging member 22 is swingably arranged on one side of the supporting plate, and the movable blade is swingably arranged on the other side of the supporting plate through the first rotating shaft 51.

[0106] The second end of the swinging member 22 is provided with a mating protrusion 221, the movable blade is provided with a mating groove 211, and the support plate is provided with an escape groove. This allows the mating protrusion 221 to pass through the escape groove and mate with the mating groove 211 on the movable blade, thereby enabling the swinging member 22 to smoothly drive the movable blade. The escape groove is an arc-shaped groove to accommodate the swinging path of the mating protrusion 221, avoiding the possibility of an oversized groove on the support plate that would affect its structural strength.

[0107] In some optional embodiments of the present invention, Figure 11 、 Figure 12 As shown, each movable blade mechanism 20 has multiple movable blades and swinging members 22, and the multiple movable blades and the multiple swinging members 22 are movably matched in a one-to-one correspondence. The multiple movable blades are arranged along the extension direction of the opening 111. When the swinging member 22 swings and drives the movable blades to swing, the multiple movable blades can extend from the opening 111 to the outside of the accommodating cavity 11, so as to use the multiple movable blades to cut hair and other fibrous garbage outside the accommodating cavity 11, thereby increasing the cuttable area of ​​the cutting assembly 1 and improving the cutting efficiency of the cutting assembly 1.

[0108] Among them, the movable knife mechanism 20 also includes a connecting member 23, which is movably connected to multiple swinging members 22. The driving member 30 is used to drive the connecting member 23 to move or one of the swinging members 22 to swing, so that the multiple swinging members 22 can swing synchronously. In this way, one driving member 30 can simultaneously drive multiple swinging members 22 to swing synchronously, and then drive multiple movable blades to swing, so that the movable blades can simultaneously cut hair and other fibrous garbage outside the accommodating cavity 11.

[0109] In some embodiments, as Figure 11As shown, the extension direction of the rotation axis of the movable blade is perpendicular to the extension direction of the opening 111, so that the rotation plane of the movable blade is parallel to the extension direction of the opening 111, and the axial direction of the roller brush 62 in the cleaning device is parallel to the extension direction of the opening 111. The rotation plane of the movable blade is parallel to the axial direction of the roller brush 62, so that multiple movable blades are arranged along the axial direction of the roller brush 62, so that the area swept by the multiple movable blades when swinging can cover the axial length of the roller brush 62, thereby increasing the cleaning area of ​​the movable blade on the roller brush 62, and improving the cleaning effect of the cutting assembly 1 on the roller brush 62.

[0110] In some embodiments, the driving member 30 is used to drive the connecting member 23 to swing. The connecting member 23 is rotatably connected to multiple swinging members 22. When the connecting member 23 swings, it can drive multiple swinging members 22 to swing at the same time. The multiple swinging members 22 can drive multiple moving blades to swing at the same time, so that the multiple moving blades can cut fibrous garbage such as hair outside the accommodating cavity 11.

[0111] In other embodiments, the driving member 30 is used to drive the connecting member 23 to move, and the connecting member 23 slides with the multiple swinging members 22 respectively. For example, the connecting member 23 is provided with multiple protrusions, and the swinging member 22 is provided with a slide groove. The protrusions and the slide grooves correspond to each other one by one. When the driving member 30 drives the connecting member 23 to move, the protrusion drives the swinging member 22 to swing, and the distance between the protrusion and the swinging center of the swinging member 22 changes, so that the protrusion slides with the slide groove, so that the connecting member 23 can smoothly drive the multiple swinging members 22 to swing, thereby avoiding the connecting member 23 and the swinging member 22 from being stuck at a certain position.

[0112] In some other embodiments, the driving member 30 is used to drive the connecting member 23 to move. The connecting member 23 and the multiple swinging members 22 are matched in a gear rack manner. When the connecting member 23 moves, the connecting member 23 can drive the multiple swinging members 22 to swing at the same time. The multiple swinging members 22 can drive the multiple movable blades to swing at the same time, so that the multiple movable blades can cut the hair and other fibrous garbage outside the accommodating cavity 11.

[0113] In some specific embodiments of the present invention, Figure 11 、 Figure 12 As shown, multiple swinging members 22 are rotationally connected to the shell 10 through the second rotating shaft 52, and the connecting member 23 is rotationally connected to the swinging member 22 through the third rotating shaft 53. The second rotating shaft 52 and the third rotating shaft 53 on each swinging member 22 are spaced apart. When the connecting member 23 moves, the connecting member 23 provides a force to the swinging member 22 through the third rotating shaft 53, so that the second rotating shaft 52 and the third rotating shaft 53 are spaced apart to ensure that the connecting member 23 can provide sufficient torque to the swinging member 22 to drive the swinging member 22 to swing.

[0114] Specifically, in an embodiment in which the driving member 30 drives the connecting member 23 to move, the connecting member 23 drives multiple swinging members 22 to swing together through the third rotating shaft 53, so that the third rotating shaft 53 is spaced apart from the second rotating shaft 52, so that the connecting member 23 can provide sufficient torque to the swinging member 22 when it moves to drive the swinging member 22 to swing.

[0115] In an embodiment in which the driving member 30 drives one of the swinging members 22 to swing, this swinging member 22 drives the connecting member 23 to move through the third rotating shaft 53, so that the third rotating shaft 53 is spaced apart from the second rotating shaft 52, so that this swinging member 22 provides sufficient torque to the connecting member 23, and the connecting member 23 can move smoothly, so that the connecting member 23 can drive the other swinging members 22 to swing together.

[0116] In some embodiments, as Figure 11 As shown, the housing 10 has a second avoidance groove 12 , and the third rotating shaft 53 is passed through the second avoidance groove 12 so that the third rotating shaft 53 can be smoothly connected to the connecting member 23 .

[0117] like Figure 11 、 Figure 12 As shown, in this embodiment, the shell 10 includes a supporting plate, which is arranged in the accommodating cavity 11, and the swinging member 22 and the connecting member 23 are arranged on different sides of the supporting plate. The swinging member 22 is swingably arranged on one side of the supporting plate, and the connecting member 23 is movably arranged on the other side of the supporting plate. A second avoidance groove 12 is provided on the supporting plate so that one end of the third rotating shaft 53 is connected to the swinging member 22, and the other end can pass through the supporting plate and be connected to the connecting member 23.

[0118] The swing member 22 and the connecting member 23 are arranged on different sides of the supporting plate, so that the supporting plate provides support for the swing of the swing member 22 and the movement of the connecting member 23, so that the swing member 22 can swing stably and the connecting member 23 can move stably.

[0119] In some examples, the second avoidance groove 12 is an arc-shaped groove. Since the third rotating shaft 53 swings around the second rotating shaft 52, the moving trajectory of the third rotating shaft 53 is an arc line, so that the second avoidance groove 12 is an arc-shaped groove to adapt to the moving trajectory of the third rotating shaft 53 and avoid the inner wall of the second avoidance groove 12 interfering with the swing of the third rotating shaft 53.

[0120] In other examples, such as Figure 11 As shown, the second avoidance groove 12 is a straight groove with a groove width greater than the diameter of the third rotating shaft 53. Since the third rotating shaft 53 swings around the second rotating shaft 52, the moving trajectory of the third rotating shaft 53 is an arc line, so that the groove width of the second avoidance groove 12 is greater than the diameter of the third rotating shaft 53, so as to reserve space for the swing of the third rotating shaft 53 in the second avoidance groove 12, thereby preventing the inner wall of the second avoidance groove 12 from interfering with the swing of the third rotating shaft 53.

[0121] In some specific embodiments of the present invention, Figure 11 As shown, one of the shell 10 and the connecting member 23 is provided with a limiting groove 13, and the other is provided with a limiting protrusion 231, wherein the limiting protrusion 231 slides with the limiting groove 13. When the limiting protrusion 231 slides to the two ends of the limiting groove 13, the movable blade switches to the first state. At this time, the cleaning device can be used normally to clean the surface to be cleaned, avoiding the movable blade from affecting the rolling of the roller brush 62 in the cleaning device, and avoiding the movable blade from scratching the user when the user cleans the cleaning device, thereby improving the safety of the cleaning device.

[0122] like Figure 12 As shown, in this embodiment, a limiting groove 13 is provided on the shell 10, and a limiting protrusion 231 is provided on the connecting member 23. When the limiting protrusion 231 and the end of the limiting groove 13 are stopped, the movable blade is received in the accommodating cavity 11. By providing the limiting groove 13, the swing range of the connecting member 23 can be limited, and then the swing range of the movable blade can be limited, thereby preventing the movable blade from sweeping over too large an area in the accommodating cavity 11 and affecting the distribution of space in the accommodating cavity 11.

[0123] In some embodiments, the limiting groove 13 and at least one second avoidance groove 12 are the same groove body, and the second avoidance groove 12 is abutted against the third rotating shaft 53 , and the movable blade is accommodated in the accommodating cavity 11 .

[0124] In some examples, a plurality of second avoidance grooves 12 are provided on the shell 10, and at least one of the plurality of second avoidance grooves 12 can be used as a limiting groove 13. Correspondingly, the third rotating shaft 53 located in the limiting groove 13 can be used as a limiting protrusion 231. When the third rotating shaft 53 is stopped and engaged with the end of the second avoidance groove 12, the movable blade is accommodated in the accommodating cavity 11.

[0125] In other embodiments, the limiting groove 13 and the second avoidance groove 12 are different groove bodies. The limiting groove 13 and the second avoidance groove 12 can both be arc-shaped grooves or straight-line grooves, or one of them can be an arc-shaped groove and the other can be a straight-line groove.

[0126] In some examples, such as Figure 17 As shown, a limiting groove 13 is provided on the shell 10, and a limiting protrusion 231 is provided on the connecting member 23. The limiting protrusion 231 can be used as a third rotating shaft 53. The swinging member 22 is rotatably connected to the third rotating shaft 53, and the connecting member 23 drives the swinging member 22 to swing through the limiting protrusion 231.

[0127] like Figure 12As shown, in this embodiment, the limiting groove 13 is an arc-shaped groove, and the second avoidance groove 12 is a linear groove. When the swinging member 22 swings, the third rotating shaft 53 swings in the second avoidance groove 12, and the limiting protrusion 231 slides in the limiting groove 13. When the limiting protrusion 231 and the limiting groove 13 are stopped and engaged, the movable blade is received in the accommodating cavity 11.

[0128] In some specific embodiments of the present invention, Figure 12 As shown, the movable knife mechanism 20 also includes a reset member 24, which is used to drive the connecting member 23 to move to a position where the limiting protrusion 231 stops at one end of the limiting groove 13, so as to automatically accommodate the movable blade in the accommodating chamber 11. In this way, there is no need to use the driving member 30 to drive the movable blade to swing to a position accommodated in the accommodating chamber 11, thereby improving the safety of the cutting assembly 1.

[0129] Specifically, after the cutting assembly 1 completes cutting of the fibrous garbage outside the accommodating chamber 11 and the driving member 30 stops working, the reset member 24 can drive the connecting member 23 to move to a position where the limiting protrusion 231 and one end of the limiting groove 13 abut against each other, so as to automatically store the movable blade in the accommodating chamber 11, thereby preventing the movable blade from scratching the user, thereby improving the safety of the cutting assembly 1.

[0130] In some embodiments, as Figure 12 As shown, the extension direction of the opening 111 extends along the left and right directions (it should be understood here that the above direction limitation is only for the convenience of describing the accompanying drawings and will not limit the actual setting position and direction of the cutting component 1 of the cleaning equipment). The reset member 24 is a spring member, one end of the reset member 24 stops at the shell 10, and the other end stops at the connecting member 23. The reset member 24 has a rightward driving force on the connecting member 23, so as to drive the limiting protrusion 231 to stop and cooperate with the right end of the limiting groove 13, thereby automatically storing the movable blade in the accommodating cavity 11.

[0131] In some embodiments of the present invention, the cutting assembly 1 further includes a fixed blade 40, which is fixed to the housing 10 and partially extends out of the accommodating cavity 11 from the opening 111. When the movable blade is switched to the second state, the movable blade fits into the fixed blade 40 so that the blade edge of the fixed blade 40 and the blade portion 2021 of the movable blade form a scissors structure, so as to be able to cut off fibrous garbage such as hair.

[0132] Specifically, when the hardness of the fibrous garbage is relatively high, it is not easy to cut the fibrous garbage by relying solely on the blade portion 2021 on the movable blade. By providing a fixed blade 40, when the movable blade rotates, the movable blade can hook the fibrous garbage to the blade of the fixed blade 40, so that the scissors structure formed by the fixed blade 40 and the movable blade can cut the fibrous garbage.

[0133] In some embodiments, the housing 10 includes a first shell portion 101 , a second shell portion 102 and a supporting plate. The first shell portion 101 and the second shell portion 102 define a receiving cavity 11 . The supporting plate is disposed between the first shell portion 101 and the second shell portion 102 .

[0134] In some examples, the supporting plate is fixed to the first shell 101, the swinging member 22 and the moving blade are arranged on the same side of the supporting plate, the swinging member 22 and the moving blade are arranged between the supporting plate and the second shell 102, the swinging member 22 is swingably arranged on the supporting plate, the moving blade is located on the side of the swinging member 22 away from the supporting plate, and the fixed blade 40 is arranged on the second shell 102 so that the moving blade and the fixed blade 40 are in contact with each other to form a scissors structure.

[0135] In other embodiments, the supporting plate is fixed to the first shell 101, the swinging member 22 and the moving blade are arranged on the same side of the supporting plate, the swinging member 22 and the moving blade are arranged between the supporting plate and the second shell 102, the swinging member 22 is swingably arranged between the second shell 102 and the supporting plate, the moving blade is located on the side of the swinging member 22 facing the supporting plate, and the fixed blade 40 can be arranged on the supporting plate so that the moving blade and the fixed blade 40 are in contact with each other to form a scissors structure.

[0136] In some other embodiments, the supporting plate is located between the first shell 101 and the second shell 102, the swinging member 22 and the movable blade are arranged on different sides of the supporting plate, the swinging member 22 can be swingably arranged between the first shell 101 and the supporting plate, the movable blade can be swingably arranged between the second shell 102 and the supporting plate, and the fixed blade 40 can be arranged on the supporting plate or the second shell 102 so that the movable blade can be fitted with the fixed blade 40 to form a scissors structure.

[0137] In some optional embodiments of the present invention, Figure 9 、 Figure 15 As shown, there are at least two movable knife mechanisms 20, and at least two movable knife mechanisms 20 are located on both sides of the fixed blade 40 in the thickness direction, that is, movable blades are provided on both sides of the fixed blade 40 in the thickness direction, thereby forming two sets of scissors structures.

[0138] In some embodiments, as Figure 9 、 Figure 15As shown, the cutting assembly 1 includes two movable knife mechanisms 20, which are respectively a first movable knife mechanism 20 and a second movable knife mechanism 20. The first movable knife mechanism 20 includes a plurality of first movable blades, and the second movable knife mechanism 20 includes a plurality of second movable blades. The plurality of first movable blades are arranged on one side of the thickness direction of the fixed blade 40 and are arranged at intervals along the extension direction of the opening 111. The plurality of second movable blades are arranged on the other side of the thickness direction of the fixed blade 40 and are arranged at intervals along the extension direction of the opening 111. In the thickness direction of the fixed blade 40, the first movable blades and the second movable blades are staggered to reasonably and densely arrange the plurality of first movable blades and the plurality of second movable blades, which facilitates improving the cutting effect of the cutting assembly 1.

[0139] Specifically, since the first movable blade and the second movable blade are located on both sides of the thickness direction of the fixed blade 40, the rotation of the first movable blade and the second movable blade will not interfere with each other. Therefore, the first movable blade and the second movable blade can be set relatively close to each other, so that a plurality of movable blades can be densely arranged in the extension direction of the opening 111, so that the plurality of movable blades can fully cut the hair and other fibrous garbage on the roller brush 62 to fully clean the roller brush 62.

[0140] In some embodiments, as Figure 9 、 Figure 10 As shown, the shell 10 includes a first shell portion 101, a second shell portion 102 and a first supporting plate 1031. The first shell portion 101 and the second shell portion 102 define an accommodating cavity 11. The first supporting plate 1031 is arranged in the accommodating cavity 11 and divides the accommodating cavity 11 into two chambers. The two movable knife mechanisms 20 are arranged on both sides of the first supporting plate 1031 in the thickness direction.

[0141] The swinging member 22 and the movable blade of the first movable knife mechanism 20 are located between the first supporting plate 1031 and the first housing 101. The connecting member 23 of the first movable knife mechanism 20 is located on the side of the first housing 101 facing away from the first supporting plate 1031. The swinging member 22 is located between the movable blade and the first housing 101. The movable blade is swingably mounted on the first housing 10 via a first rotating shaft 51. A first avoidance groove 222 is provided on the swinging member 22. One end of the first rotating shaft 51 is connected to the swinging member 22, and the other end passes through the first avoidance groove 222 and is connected to the first housing 10. The swinging member 22 is swingably mounted on the first housing 10 via a second rotating shaft 52. The swinging member 22 is connected to the connecting member 23 via a third rotating shaft 53. A second avoidance groove 12 is provided on the first housing 10. One end of the third rotating shaft 53 is movably coupled to the swinging member 22, and the other end passes through the second avoidance groove 12 and is connected to the connecting member 23.

[0142] The swinging member 22 and the movable blade of the second movable knife mechanism 20 are located between the first supporting plate 1031 and the second housing 10. The connecting member 23 of the second movable knife mechanism 20 is located on the side of the second housing 102 facing away from the first supporting plate 1031. The swinging member 22 is located between the movable blade and the second housing 102. The movable blade is swingably mounted on the second housing 10 via a first rotating shaft 51. A first avoidance groove 222 is provided on the swinging member 22. One end of the first rotating shaft 51 is connected to the swinging member 22, and the other end passes through the first avoidance groove 222 and is connected to the second housing 10. The swinging member 22 is swingably mounted on the second housing 10 via a second rotating shaft 52. The swinging member 22 is connected to the connecting member 23 via a third rotating shaft 53. A second avoidance groove 12 is provided on the second housing 10. One end of the third rotating shaft 53 is movably connected to the swinging member 22, and the other end passes through the second avoidance groove 12 and is connected to the connecting member 23.

[0143] The fixed blade 40 is provided on the first supporting plate 1031 or the first supporting plate 1031 is formed into the fixed blade 40 so that the fixed blade 40 fits with the movable blade of the first movable blade mechanism 20 and fits with the movable blade of the second movable blade mechanism 20 .

[0144] In some embodiments, the housing 10 further includes two second supporting plates 1032, one of which is located between the first housing 10 and the first supporting plate 1031, and the other is located between the second housing 10 and the first supporting plate 1031. Specifically, the second supporting plate 1032 is located between the movable blade and the swinging member 22, so that the second supporting plate 1032 supports the swinging of the movable blade and the swinging member 22, thereby allowing the movable blade and the swinging member 22 to swing stably.

[0145] In some examples, a clearance hole is provided on the second supporting plate 1032, so that one end of the first rotating shaft 51 is connected to the movable blade, and the other end can pass through the second supporting plate 1032 and the first clearance slot 222 on the swinging member 22 and be rotatably provided on the first housing 10 or the second housing 10. In other examples, one end of the first rotating shaft 51 is connected to the movable blade, and the other end is rotatably provided on the second supporting plate 1032. In this embodiment, the first clearance slot 222 is not required on the swinging member 22.

[0146] Furthermore, because the swinging member 22 and the moving blade slide together via the mating protrusion 221 and the mating groove 211, a fourth relief groove is provided on the second carrier plate 1032. The mating protrusion 221 on the swinging member 22 passes through the fourth relief groove and mates with the mating groove 211 on the moving blade. The fourth relief groove is an arc-shaped groove to accommodate the movement path of the mating protrusion 221 and prevent the inner wall of the fourth relief groove from interfering with the movement of the mating protrusion 221.

[0147] In some specific embodiments of the present invention, Figure 9As shown, the driving member 30 is used to drive the swinging members 22 of at least two movable knife mechanisms 20 to swing synchronously, thereby realizing the synchronous swinging of the movable blades of the two movable knife mechanisms 20, so that multiple movable knives swing synchronously to cut hair and other fibrous garbage outside the accommodating cavity 11.

[0148] like Figure 9 As shown, in this embodiment, the cutting assembly 1 includes two movable knife mechanisms 20, and the movable knife mechanisms 20 include a connecting member 23, which is movably connected to a plurality of swinging members 22 to drive the plurality of swinging members 22 to swing synchronously, wherein the connecting members 23 of the two movable knife mechanisms 20 are linked, and the driving member 30 is used to drive one of the connecting members 23 to move, so as to drive the swinging members 22 in the two movable knife mechanisms 20 to swing synchronously, so that the movable blades in the two movable knife mechanisms 20 can swing synchronously.

[0149] In other specific embodiments of the present invention, there are at least two driving members 30, and the two driving members 30 are used to respectively drive the swinging members 22 of the two moving knife mechanisms 20 to swing, so that the moving blades in the two moving knife mechanisms 20 can be flexibly driven to swing.

[0150] Among them, for the convenience of description, taking two movable knife mechanisms 20 as an example, the two movable knife mechanisms 20 are respectively the first movable knife mechanism 20 and the second movable knife mechanism 20, the first movable knife mechanism 20 includes multiple first movable blades, and the second movable knife mechanism 20 includes multiple second movable blades. The two driving members 30 can drive one of the first movable blade and the second movable blade to swing, or drive the first movable blade and the second movable blade to swing synchronously or successively, so as to flexibly control the swinging mode of multiple movable blades according to needs.

[0151] The cleaning device according to an embodiment of the present invention is described below. The cleaning device according to an embodiment of the present invention comprises the cutting assembly 1 according to the above-mentioned embodiment of the present invention.

[0152] According to the cleaning device of the embodiment of the present invention, by utilizing the cutting component 1 according to the above-mentioned embodiment of the present invention, by setting the protrusion 2022, the protrusion 2022 is used to hook the hair and other fibrous materials, and the hair and other fibrous materials can be pulled in the direction away from the roller brush 62, so that it is convenient for the blade part 2021 to cut the hair and other fibrous garbage, so as to cut the hair and other fibrous garbage into shredded garbage, so that the fibrous garbage will not continue to be entangled on the roller brush 62 due to its shortened length, so as to facilitate the cleaning of the hair and other fibrous garbage and ensure the normal use of the roller brush 62.

[0153] In some embodiments of the present invention, Figures 18-20As shown, the cleaning device defines a cleaning chamber with a dust inlet, and a rotatable roller brush 62 is provided in the cleaning chamber. The roller brush 62 includes a rotating rod 621 and a plurality of bristles 622. The plurality of bristles 622 are provided on the peripheral wall of the rotating rod 621. When the cleaning device is working, the roller brush 62 rotates to use the plurality of bristles 622 to clean the surface to be cleaned.

[0154] In which, when the movable blade extends out of the accommodating cavity 11, the protrusion 2022 of the movable blade extends between the multiple bristles 622 of the roller brush 62. When the movable blade swings, the protrusion 2022 can hook the fibrous garbage on the roller brush 62 and guide the fiber material to the blade portion 2021. The fiber material can be confined between the blade portion 2021 and the protrusion 2022, so that the blade portion 2021 can smoothly cut off the fiber material, preventing the fiber material from slipping out of the blade portion 2021 and preventing the fiber material from being entangled on the cutting blade 200.

[0155] The axial direction of the roller brush 62 is consistent with the extension direction of the opening 111 , so that the protrusion 2022 can make more contact with the bristles 622 during its sweeping range, so that the protrusion 2022 can fully hook the hair and other fibrous garbage wrapped around the bristles 622 .

[0156] In some embodiments, the protrusion 2022 is spaced apart from the rotating rod 621 to prevent the protrusion 2022 from scratching the rotating rod 621 when the protrusion 2022 is used to hook hair and other fibrous waste wrapped around the bristles 622. Specifically, the protrusion 2022 is inserted into the bristles 622 so that the protrusion 2022 can hook hair and other fibrous waste tightly wrapped around the bristles 622, thereby improving the cutting effect of the cutting assembly 1 on the fibrous waste and improving the efficiency of the cutting assembly 1 in cutting the fibrous waste.

[0157] In other embodiments, one end of the protrusion 2022 away from the blade portion 2021 is formed into a rounded corner. When the movable blade swings, the distance between the protrusion 2022 and the rotating rod 621 is closer or the protrusion 2022 can contact the rotating rod 621 when swinging, so that the protrusion 2022 can hook the hair and other fibrous garbage tightly wrapped around the roller brush 62, so as to fully cut off the hair and other fibrous garbage wrapped around the roller brush 62, so that the fibrous garbage will not continue to wrap around the roller brush 62 due to its shortened length, thereby achieving the cleaning of the roller brush 62.

[0158] like Figure 11 、 Figure 12As shown, in this embodiment, the cutting assembly 1 includes a plurality of movable blades, which are arranged along the extension direction of the opening 111, so that the axial direction of the roller brush 62 is consistent with the extension direction of the opening 111, so that the sweeping area of ​​the plurality of protrusions 2022 can cover the axial length of the roller brush 62, thereby ensuring that the protrusions 2022 fully hook the hair and other fibrous garbage wrapped around the roller brush 62.

[0159] In some embodiments, the rotation axis of the movable blade is perpendicular to the extension direction of the opening 111, and the rotation plane of the movable blade is parallel to the extension direction of the opening 111, so as to increase the overlapping area of ​​the sweeping range of the bristles 622 and the protrusion 2022, so that the protrusion 2022 can fully hook the hair and other fibrous garbage wrapped around the roller brush 62, thereby facilitating the blade portion 2021 to cut off the hair and other fibrous garbage.

[0160] In some optional embodiments of the present invention, the cleaning device also has a dust suction channel and a dust suction port, and the dust suction port connects the cleaning chamber and the dust suction channel. When the cleaning device is working, the garbage on the surface to be cleaned enters the cleaning chamber from the dust inlet and enters the dust suction channel from the dust suction port. The cutting component 1 is arranged above the roller brush 62 and close to the dust suction port. In this way, after the cutting component 1 cuts the hair and other fibrous garbage on the roller brush 62 into crushed garbage, it is convenient for the crushed garbage to enter the dust suction channel from the dust suction port, thereby preventing the crushed garbage from falling onto the surface to be cleaned and affecting the cleaning of the surface to be cleaned by the cleaning device.

[0161] In some optional embodiments of the present invention, Figure 19 As shown, the roller brush 62 includes multiple rows of bristles 622 and rubber strips 65. The single row of bristles 622 extends along the axial direction of the rotating rod 621, and the multiple rows of bristles 622 are arranged along the circumference of the rotating rod 621. A rubber strip 65 is provided between two adjacent rows of bristles 622. The rubber strip 65 is used to reduce the gap between the cleaning device and the surface to be cleaned, so as to increase the suction force of the cleaning device so that the cleaning device can suck up the garbage on the surface to be cleaned, thereby cleaning the surface to be cleaned.

[0162] In some optional embodiments of the present invention, when the swinging member 22 drives the movable blade to swing, the roller brush 62 is in a stopped state to prevent the blade portion 2021 from cutting the bristles 622 on the roller brush 62 .

[0163] Among them, the movable blade can cut hair and other fibrous garbage in the upper part of the roller brush 62 facing it when swinging. Specifically, when the cleaning equipment needs to clean the roller brush 62, the roller brush 62 is controlled to stop rotating, and the driving member 30 works for the first time. At this time, the driving member 30 drives the movable blade to swing through the swinging member 22 to cut the fibrous garbage wrapped in the upper part of the roller brush 62. After the driving member 30 works for more than a preset time and the movable blade is stored in the accommodating chamber 11, the driving member 30 stops working. At this time, the roller brush 62 is controlled to rotate for a first preset angle and then stop rotating. The driving member 30 works for a second time to cut the fibrous garbage wrapped in other parts of the roller brush 62.

[0164] By repeating the above process, the fibrous garbage entangled circumferentially around the roller brush 62 can be fully cut, and the longer fibrous garbage can be cut into shredded garbage, so as to facilitate the cleaning of the fibrous garbage.

[0165] In some embodiments, the first preset angle is less than 360°. For example, the first preset angle may be 30°, 45°, 90°, 135°, 150°, or 180°.

[0166] Other structures and operations of the cleaning device according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail here.
