[0034] The embodiments of the present invention are described in detail below, and 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 only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, inside, outside, top, bottom, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0036] In the description of the present utility model, "a plurality" means more than two. If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0037] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0038] With the advancement of science and technology, smart home appliances have also developed rapidly. For example, cleaning equipment such as sweeping robots can help people clean the floor, greatly reducing the labor intensity and time of cleaning. In related technologies, cleaning equipment will be equipped with cleaning components such as a roller for cleaning at the bottom of its main body. When the cleaning equipment moves, it can drive the cleaning components to move, thereby cleaning the floor.

[0039] However, due to the small size of the cleaning component, the outer wall of the equipment body is generally located on the outside of the cleaning component in the projection in the height direction of the equipment body. Therefore, when cleaning the corners of the floor, even if the cleaning equipment moves the outer wall of its equipment body to abut the wall of the corner area, there is still a certain distance between the cleaning component and the wall of the corner area, which makes it difficult for the cleaning component to thoroughly clean the corners of the floor, resulting in poor cleaning effect.

[0040] Therefore, the utility model provides a cleaning device, which can effectively improve the above problems.

[0041] Reference below Figures 1 to 6 A cleaning device according to an embodiment of the present invention is described.

[0042] like Figure 1 and Figure 2 As shown, the cleaning device according to the embodiment of the present utility model includes a device body 100 and a cleaning component 200.

[0043] For example, the device body 100 may be in a disc shape, a square disc shape, or other suitable shapes. A travel wheel may be installed at the bottom of the device body 100 to drive the cleaning device to move.

[0044] The cleaning component 200 may be a roller, a roller brush, a crawler rag, a cleaning nozzle or other suitable cleaning components. Taking the cleaning component 200 as a roller as an example, the cleaning component 200 may be horizontally mounted at the bottom end of the device body 100, that is, the axial direction of the cleaning component 200 extends in the horizontal direction, and the cleaning component 200 may rotate around its own axis. The cleaning component 200 may be movable and adjustable in a first direction, which may be a horizontal direction or slightly inclined relative to the horizontal direction. The moving direction of the cleaning component 200 may be the axial direction of the cleaning component 200, or may be at a certain angle to the axial direction of the cleaning component 200. During the movement of the cleaning component 200, the cleaning component 200 may be moved to be flush with the projection of the outer contour of the device body 100 in the height direction of the device body 100, or may be moved to at least partially extend beyond the projection of the outer contour of the device body 100 in the height direction.

[0045] According to the cleaning device of the embodiment of the utility model, the cleaning assembly 200 is installed on the device body 100 of the cleaning device, and the cleaning device drives the cleaning assembly 200 to move, and the cleaning assembly 200 can clean different positions of the ground. When it is necessary to clean the corner area of ​​the ground, the cleaning assembly 200 can be moved and adjusted along the first direction, so that the cleaning assembly 200 is flush with the projection of the outer contour of the device body 100 along the height direction, or the cleaning assembly 200 is at least partially extended from the projection of the outer contour of the device body 100 along the height direction, and then the cleaning assembly 200 can be located in the corner area of ​​the ground, so that the cleaning assembly 200 is convenient for cleaning the corner area of ​​the ground. In addition, when the cleaning assembly 200 can be moved to at least partially extend from the projection of the outer contour of the device body 100 along the height direction, it is also convenient to clean the area with a small space. Even if the cleaning device as a whole is difficult to move into the area with a small space, the cleaning assembly 200 extending outside the device body 100 can also be moved alone to the area with a small space for cleaning, and the cleaning effect is better.

[0046] It should be noted that the cleaning component 200 can be moved to be flush with the projection of the outer contour of the device body 100 along the height direction, which means that the cleaning component 200 is located directly below the device body 100 as a whole, and one of the positions of the cleaning component 200 is flush with the projection of the outer contour of the device body 100 along the height direction. For example, when the cleaning component 200 is a roller, the end face of one end of the axial direction of the cleaning component 200 can be flush with the projection of the outer contour of the device body 100 along the height direction. Of course, it can also be that the outer wall of the cleaning component 200 is flush with the projection of the outer contour of the device body 100 along the height direction, or it can be that other positions are flush with the projection of the outer contour of the device body 100 along the height direction. The cleaning component 200 can be moved to at least partially extend from the projection of the outer contour of the device body 100 along the height direction, which can be the cleaning component 200 can be moved to partially extend from the projection of the outer contour of the device body 100 along the height direction, or it can be the cleaning component 200 can be moved to the projection of the outer contour of the device body 100 along the height direction, which is set according to actual needs.

[0047] refer to Figures 1 to 6 As shown, in some embodiments of the present invention, the device body 100 is provided with a mounting seat 201 that slides along a first direction, the cleaning component 200 is disposed on the mounting seat 201, and a driving mechanism 300 is provided between the mounting seat 201 and the device body 100, and the driving mechanism 300 is used to control the sliding of the mounting seat 201.

[0048] For example, the device body 100 can be provided with a bracket 400, and the bracket 400 can be provided with a plurality of slide grooves 401. The slide grooves 401 extend along the sliding direction of the mounting seat 201, that is, the first direction. The mounting seat 201 can be provided with a corresponding sliding portion 202, and the sliding portion 202 is slidably installed in the slide groove 401, thereby realizing the sliding of the mounting seat 201, thereby realizing the movement and adjustment of the cleaning component 200. The slide groove 401 can pass through up and down, and the sliding portion 202 can be inserted into the slide groove 401. A limit head can be provided at one end of the sliding portion 202 away from the mounting seat 201, and the size of the limit head is larger than the width of the slide groove 401 to prevent the sliding portion 202 from moving out of the slide groove 401 at will. When the cleaning component 200 is configured as a roller, the mounting seat 201 may be provided with a accommodating cavity 203 with an opening facing downward, and the inner wall of the accommodating cavity 203 may be roughly an arc surface. The cleaning component 200 can be rotatably installed in the accommodating cavity 203. Specifically, bearings may be provided at both ends of the accommodating cavity 203, and connecting shafts may be provided at both axial ends of the cleaning component 200, and the connecting shafts are rotatably installed in the bearings. Of course, connecting shafts may also be provided at both ends of the accommodating cavity 203, and mounting holes may be provided at both axial ends of the cleaning component 200, and the connecting shafts are installed in the mounting holes.

[0049] In this embodiment, the driving mechanism 300 is started, and the driving mechanism 300 can control the mounting seat 201 to slide, thereby realizing the movement and adjustment of the cleaning component 200, which has a simple structure, is easy to operate, and saves time and effort.

[0050] It should be noted that in some other embodiments of the present invention, the bracket 400 may be provided with a guide rail, and the mounting seat 201 may be slidably mounted on the guide rail. In addition, the mounting seat 201 may be provided with a slide groove 401, and the bracket 400 may be provided with a connecting portion that can be slidably connected to the slide groove 401. In addition, the driving mechanism 300 may not be provided, but the mounting seat 201 may be manually slidably adjusted, and when the mounting seat 201 slides to a set position, the mounting seat 201 may be locked by a bolt or a limit pin.

[0051] refer to Figures 3 to 5 As shown, in a further embodiment of the utility model, the driving mechanism 300 includes a screw rod 301 and a first driving member 302, the screw rod 301 is rotatably disposed on one of the device body 100 and the mounting base 201, the screw rod 301 is threadedly connected to the other of the device body 100 and the mounting base 201, the screw rod 301 extends along a first direction, and the first driving member 302 is connected to the screw rod 301 to control the rotation of the screw rod 301.

[0052] For example, the bracket 400 of the device body 100 may be provided with two brackets 402 arranged along the sliding direction of the mounting seat 201, the two ends of the screw rod 301 are rotatably mounted on the two brackets 402 respectively, the outer wall of the screw rod 301 is provided with an external thread, and the first driving member 302 is installed on the bracket 400 and is transmission-connected to the screw rod 301. The mounting seat 201 may be provided with a threaded seat 204, the threaded seat 204 is provided with a threaded hole, the internal thread of the inner wall of the threaded hole is adapted to the external thread of the outer wall of the screw rod 301, and the threaded seat 204 is threadedly connected to the screw rod 301 through the matching thread of the internal thread and the external thread.

[0053] In this embodiment, starting the first driving member 302 can drive the screw rod 301 to rotate, and the mounting seat 201 is threadedly connected to the screw rod 301 through the threaded seat 204. The mounting seat 201 itself is slidably installed on the bracket 400 and cannot rotate with the screw rod 301. Therefore, the rotation of the screw rod 301 can be converted into the sliding of the mounting seat 201. The structure is simple, the operation is convenient, and it saves time and effort.

[0054] It should be noted that the screw rod 301 may be rotatably mounted on the mounting seat 201, and the screw rod 301 is threadedly connected to the bracket 400 on the device body 100. The first driving member 302 may be a driving motor, and the output shaft of the driving motor is coaxially connected to the screw rod 301. In addition, the first driving member 302 may also include a driving motor and a transmission structure, and the transmission structure may be a gear reducer, and the driving motor indirectly controls the rotation of the screw rod 301 through the transmission structure. It is understandable that the driving mechanism 300 may also be other structures, for example, it may be an electric push rod disposed between the device body 100 and the mounting seat 201, and the electric push rod controls the sliding of the mounting seat 201 through its own telescopic movement.

[0055] refer to Figure 1 and Figure 2 As shown, in some embodiments of the utility model, the first direction is perpendicular to the moving direction of the device body 100, so that the cleaning component 200 can be moved to be roughly flush with the outer contour of one side of the moving direction of the device body 100, or extend out of one side of the moving direction of the device body 100, so that when cleaning the corner area of ​​the floor, the cleaning component 200 can be located in the corner area of ​​the floor, and then the device body 100 can be moved along the wall to clean the corner area of ​​the floor, which makes cleaning more convenient.

[0056] It is understandable that the first direction may be a horizontal direction. In this case, when the device body 100 moves along its front-rear direction, the first direction may be the left-right direction of the device body 100, and the cleaning assembly 200 moves and adjusts along the left-right direction of the device body 100. Of course, the first direction may also be slightly inclined relative to the horizontal direction.

[0057] It should be noted that in some other embodiments of the present invention, the first direction may also form a certain angle with the direction perpendicular to the moving direction of the device body 100, and the angle may be 5°, 10°, 15°, 20° or other suitable degrees.

[0058] refer to Figures 3 to 6 As shown, in some embodiments of the present invention, the device body 100 is provided with a bracket 400 that floats along the height direction of the device body 100, and the cleaning assembly 200 is arranged on the bracket 400. The cleaning assembly 200 is installed on the bracket 400 that can float along the height direction of the device body 100. When the cleaning assembly 200 passes through an uneven ground or an obstacle, it is subjected to the force applied by the uneven ground or the obstacle, and can passively float along the height direction of the device body 100, thereby enabling the cleaning assembly 200 to smoothly pass through the uneven ground or the obstacle, thereby improving the cleaning effect and efficiency.

[0059] It should be noted that the bracket 400 mentioned in the present invention floats along the height direction of the device body 100, which means that when the cleaning component 200 passes through an uneven ground or an obstacle, the cleaning component 200 can passively rise and fall, thereby driving the bracket 400 to rise and fall, thereby realizing the bracket 400 floating along the height direction of the device body 100.

[0060] refer to Figures 3 to 6 As shown, in a further embodiment of the present invention, the device body 100 is provided with a swing frame 500 that can rotate relative to the device body 100, and the bracket 400 is connected to the swing frame 500 and can float through the swing of the swing frame 500. For example, the rotation axis of the swing frame 500 can extend in the horizontal direction, and the bracket 400 can be connected to the end of the swing frame 500 away from the device body 100. When the cleaning component 200 passes through an uneven ground or an obstacle, the swing frame 500 is subjected to the force applied by the uneven ground or the obstacle, and the swing frame 500 can swing up and down around its own rotation axis, thereby achieving the bracket 400 floating along the height direction of the device body 100, thereby achieving the cleaning component 200 floating along the height direction of the device body 100, so that the cleaning component 200 can smoothly pass through the uneven ground or the obstacle, thereby improving the cleaning effect and efficiency.

[0061] It is understandable that the extension direction of the rotation axis of the swing frame 500 can also be slightly inclined relative to the horizontal direction. The bracket 400 can also float along the height direction of the device body 100 in other ways. For example, multiple springs can be vertically arranged on the device body 100, and the bracket 400 is connected to the bottom end of the spring. When the cleaning component 200 passes through an uneven ground or an obstacle, the spring can be passively contracted by the force applied by the uneven ground or the obstacle. Through the contraction of the spring, the bracket 400 can also float along the height direction of the device body 100.

[0062] refer to Figures 3 to 6 As shown, in some embodiments of the utility model, the swing frame 500 includes a plurality of swing rods 501 rotatably connected to the device body 100 and parallel to each other, the extension direction of the rotation axis between the swing rod 501 and the device body 100 is perpendicular to the moving direction and height direction of the device body 100, and the rotation axis between all the swing rods 501 and the device body 100 can be coplanar, and the bracket 400 is connected to the end of all the swing rods 501 away from the device body 100.

[0063] For example, the lengths of all the swing rods 501 can be equal, the number of the swing rods 501 can be two, four, six, eight or other suitable numbers, a first mounting block 101 can be provided on the device body 100 corresponding to the swing rod 501, and a second mounting block 403 can be provided on the bracket 400 corresponding to the swing rod 501, one end of the swing rod 501 is installed on the first mounting block 101, and the other end is installed on the second mounting block 403.

[0064] In this embodiment, the rotation axis between all the swinging rods 501 and the device body 100 is perpendicular to the moving direction and height direction of the device body 100. Taking the movement of the device body 100 along its front-back direction as an example, the rotation axis between all the swinging rods 501 and the device body 100 extends along the left-right direction of the device body 100, and then all the swinging rods 501 can swing synchronously, thereby driving the bracket 400 to float along the height direction of the device body 100, and the structure is simple. Moreover, the swinging frame 500 has a high structural strength, so that the installation of the bracket 400 is relatively stable. In addition, it can avoid the movement of the device body 100 from interfering with the up and down floating of the cleaning component 200, which is more convenient for the cleaning component 200 to pass through uneven ground or obstacles.

[0065] It should be noted that in some other embodiments of the present invention, the swing frame 500 may also be other structures, for example, it may be an integral structure, the swing frame 500 is rotatably connected to the device body 100 via a mounting shaft, and the extension direction of the mounting shaft may also be perpendicular to the moving direction and height direction of the device body 100. In addition, the common plane of the rotation axis between all the swing rods 501 and the device body 100 may be a vertical plane, or it may be slightly inclined relative to the vertical plane.

[0066] refer to Figures 3 to 6 As shown, in a further embodiment of the utility model, there are at least two groups of swing rods 501 distributed side by side, and each group of swing rods 501 is arranged with at least two swing rods 501 along the height direction of the device body 100, and all the swing rods 501 are rotatably connected to the bracket 400, and the rotation axis between the swing rod 501 and the bracket 400 is perpendicular to the moving direction and height direction of the device body 100, and the rotation axis between the swing rod 501 and the bracket 400 can be coplanar.

[0067] For example, two groups of swing rods 501 can be distributed side by side, and the two groups of swing rods 501 can be arranged along the extension direction of the rotation axis between the swing rod 501 and the device body 100. The two groups of swing rods 501 are respectively located on both sides of the bracket 400. Each group of swing rods 501 can include two swing rods 501 arranged along the height direction of the device body 100. A parallel four-bar linkage mechanism is formed between the two swing rods 501 in the same group, the corresponding first mounting block 101 and the corresponding second mounting block 403, and the rotation axis between the swing rod 501 and the bracket 400 is parallel to the rotation axis between the swing rod 501 and the device body 100.

[0068] In this embodiment, the same group of swing arms 501 are arranged along the height direction of the device body 100, and the rotation axes between all the swing arms 501 and the bracket 400 are perpendicular to the moving direction and height direction of the device body 100, and the rotation axes between the swing arms 501 and the bracket 400 can be coplanar, so that in the process of the swing frame 500 swinging up and down, the angle between the bracket 400 and the ground can be kept roughly unchanged without deflecting relative to the ground, so that the accommodating cavity 203 of the mounting seat 201 can always face downward, so that when cleaning the cleaning component 200, it is convenient to discharge dirty water and garbage on the cleaning component 200. In addition, it can also prevent the bracket 400 from deflecting relative to the ground and interfering with the ground or obstacles, thereby avoiding affecting the movement of the cleaning equipment and avoiding damage to the bracket 400, the ground or obstacles.

[0069] It should be noted that the swing rods 501 may be arranged in three, four, five or other suitable groups side by side, and each group of swing rods 501 may be arranged vertically in three, four, five or other suitable numbers. Of course, in some other embodiments of the utility model, each group of swing rods 501 may have only one swing rod 501. In this case, the swing rod 501 may be fixedly connected to the bracket 400, and the bracket 400 swings with the swing frame 500. In addition, the common plane of the rotation axis between all the swing rods 501 and the bracket 400 may be a vertical plane, or it may be slightly inclined relative to the vertical plane.

[0070] refer to Figure 6 As shown, in some embodiments of the present invention, the cleaning device further includes a lifting mechanism 600, which is disposed on the device body 100 and connected to the bracket 400 to control the lifting of the bracket 400. In the prior art, since the cleaning components 200 such as the roller are always in contact with the ground, when the cleaning device passes over a carpet or a cleaned ground, the cleaning components 200 with dirty water attached to them are likely to stain the carpet or the cleaned ground.

[0071] In this embodiment, the support 400 not only floats by the swing of the swing frame 500, but also actively rises and falls by the lifting mechanism 600. When passing over a carpet or a cleaned floor, the lifting mechanism 600 can control the support 400 to rise, so that the cleaning component 200 is separated from the carpet or the cleaned floor, thereby preventing the cleaning component 200 with dirty water adhering to it from soiling the carpet or the cleaned floor.

[0072] refer to Figure 6 As shown, in a further embodiment of the utility model, the lifting mechanism 600 includes a traction member 601 and a second driving member 602, one end of the traction member 601 is connected to the bracket 400, the second driving member 602 is arranged on the equipment body 100 and connected to the other end of the traction member 601, and the second driving member 602 controls the lifting and lowering of the bracket 400 through the traction member 601, wherein the end of the traction member 601 close to the bracket 400 can float with the bracket 400.

[0073] In this embodiment, when the second driving member 602 is started, the second driving member 602 can control the lifting of the bracket 400 through the traction member 601, which is convenient to operate and saves time and effort. In addition, the end of the traction member 601 close to the bracket 400 can float with the bracket 400, thereby preventing the traction member 601 from interfering with the floating of the bracket 400 when the bracket 400 floats.

[0074] refer to Figure 6 As shown, in a further embodiment of the present invention, the traction member 601 is configured as a pull rope, the second driving member 602 includes a cable drum and a motor, the motor is connected to the cable drum to control the rotation of the cable drum, and one end of the pull rope away from the bracket 400 is connected to the cable drum and is wound around the outer wall of the cable drum.

[0075] In this embodiment, the motor can be started to drive the cable drum to rotate, so that the traction member 601 can be rolled up on the cable drum or unfolded from the cable drum, thereby driving the bracket 400 and the cleaning component 200 on the bracket 400 to rise and fall, with a simple structure and easy operation.

[0076] It is understandable that the traction member 601 may also be a chain. When the traction member 601 is a pull rope or a chain, the traction member 601 is a flexible member, and thus the end of the traction member 601 close to the bracket 400 can float along with the bracket 400 .

[0077] It should be noted that the second driving member 602 may also be other structures, for example, it may include a motor and a pull rod provided on the output shaft of the motor, the length direction of the pull rod may be perpendicular to the length direction of the output shaft of the motor, the length direction of the output shaft of the motor may extend in the horizontal direction, the traction member 601 is connected to the end of the pull rod, the motor is started, the motor drives the output shaft to rotate, and the output shaft can then drive the pull rod to swing, so that the end of the pull rod can be raised and lowered, thereby driving the bracket 400 and the cleaning assembly 200 to be raised and lowered through the traction member 601. In addition, the traction member 601 may also be other structures, for example, it may be a telescopic rod, and since the telescopic rod can be extended and retracted, the bottom end of the telescopic rod can float with the bracket 400, and when the traction member 601 is a telescopic rod, the second driving member 602 may be an electric push rod or a motor screw mechanism.

[0078] In some other embodiments of the present invention, the lifting mechanism 600 may also be other structures, for example, the lifting mechanism 600 may include a cam and a third driving member, the cam is rotatably mounted on the device body 100, the rotation axis of the cam extends in the horizontal direction, the bracket 400 abuts against the top of the cam, and the third driving member is arranged on the device body 100 and connected to the cam to control the rotation of the cam. The third driving member may be a motor, the output shaft of the motor is directly connected to the cam, the motor is started, and the motor can control the rotation of the cam, during the rotation of the cam, the height of the top of the cam will change, and the bracket 400 abuts against the top of the cam, so as to control the lifting of the bracket 400 and the cleaning assembly 200 on the bracket 400, with a simple structure and convenient operation. It should be noted that the third driving member may also be other structures, for example, it may include a motor and a gear reducer, and the gear reducer is arranged between the motor and the cam.

[0079] refer to Figure 6 As shown, in some embodiments of the present invention, the cleaning assembly 200 is configured as a roller. In this way, when the device body 100 drives the cleaning assembly 200 to move, the cleaning assembly 200 itself can also rotate, thereby achieving a better cleaning effect, and reducing the possibility of the cleaning assembly 200 getting stuck, which is more practical.

[0080] It should be noted that the cleaning component 200 may also be other cleaning structures, for example, a roller brush, a crawler-type rag, or a cleaning nozzle.

[0081] refer to Figures 1 to 5As shown, in a further embodiment of the utility model, when the cleaning assembly 200 is set as a roller, the cleaning assembly 200 is movably and adjustably arranged on the device body 100 along the axial direction of the cleaning assembly 200, that is, the first direction is the axial direction of the cleaning assembly 200. Such a setting makes it easier for the cleaning assembly 200 to move to the end face of one end of its axial direction to be flush with the projection of the outer contour of the device body 100 along the height direction, thereby making it easier to clean the corner areas of the ground, and the cleaning effect is better. In addition, when the cleaning assembly 200 extends out of the projection of the outer contour of the device body 100 along the height direction, it gradually extends out along its own axial direction, and the moving path of the cleaning assembly 200 occupies a smaller space, thereby reducing the interference between the cleaning assembly 200 and external objects, thereby making it easier for the cleaning assembly 200 to enter the corner areas or areas with narrow space, and the practicality is better.

[0082] refer to Figures 3 to 6 As shown, in a further embodiment of the utility model, when the cleaning assembly 200 is configured as a drum, the rotation axis between the swing frame 500 and the device body 100 is parallel to the axial direction of the cleaning assembly 200. In this embodiment, such a configuration is adopted that when the swing frame 500 swings up and down around its own rotation axis, the axial direction of the cleaning assembly 200 always extends substantially in the horizontal direction, thereby preventing the cleaning assembly 200 from interfering with the ground or obstacles due to one end being high and the other end being low, which not only prevents the ground or obstacles from hindering the work of the cleaning assembly 200, but also enables the cleaning assembly 200 to pass through uneven ground or obstacles more smoothly, thereby further improving the cleaning effect and efficiency, and preventing the cleaning assembly 200, the ground or obstacles from being damaged.

[0083] In some embodiments of the present invention, the cleaning device is configured as a sweeping robot, which cleans the floor more thoroughly, is easy to move and store, and is convenient to use.

[0084] It should be noted that the cleaning device of the present invention may also be other devices, for example, a vacuum cleaner, a floor scrubber robot or a road cleaning machine, etc., which will not be described in detail here.

[0085] It is understandable that other structures and operations of the cleaning device according to the embodiment of the utility model are known to ordinary technicians in the field and will not be described in detail here.

[0086] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
