In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0045] See also Figures 1 to 5 As shown, according to an embodiment of the present application, a cleaning device is provided. The cleaning device in this embodiment may be, for example, a floor scrubber, a floor sweeper, or a base station having a floor scrubber or a floor sweeper, and other cleaning equipment.

[0046] The cleaning device in this embodiment includes a cleaning assembly, which includes a main body 10, a cleaning member 20, a scraper bar 30 and a driving component.

[0047] The cleaning member 20 is mounted on the main body 10 and can rotate around its own axis; the scraper bar 30 is arranged on the main body 10 and extends in a direction parallel to the axis of the cleaning member 20, and the scraper bar 30 has a first position away from the surface of the cleaning member 20 and a second position against the surface of the cleaning member 20 (such as Figure 3 and Figure 4 The driving member includes a driving mechanism 41 and an elastic element 42, the driving mechanism 41 is at least used to apply an external force to the scraper strip 30 so that the scraper strip 30 switches from the second position to the first position (as shown); Figure 5 As shown), the elastic element 42 is at least used to apply an external force to the wiper strip 30 to switch the wiper strip 30 from the first position to the second position.

[0048] In this embodiment, since the cleaning assembly is provided with a driving component, when the cleaning assembly is actually used, the driving mechanism 41 of the driving component can be used to apply an external force to the scraper bar 30 to switch the scraper bar 30 from the second position to the first position. At this time, the scraper bar 30 can be away from the surface of the cleaning member 20. When the cleaning member 20 rotates along its own axis to perform a self-cleaning operation, the scraper bar 30 will not contact the cleaning member 20, will not scratch the cleaning member 20, and is not easy to cause damage to the structure of the surface of the cleaning member 20, such as fluff, etc., and is not easy to affect the water absorption of the cleaning member 20, which can improve the service life and self-cleaning effect of the cleaning member 20. In addition, when the cleaning member 20 of the cleaning assembly is in a dry suction operation (i.e., no water is sprayed on the cleaning member 20), the scraper bar 30 is kept away from the cleaning member 20, which can avoid the contact between the cleaning member 20 and the scraper bar 30 being blocked by hair, etc., and can improve the cleaning efficiency of the cleaning assembly. At the same time, when the elastic element 42 applies external force to the scraper strip 30 to switch the scraper strip 30 from the first position to the second position, the scraper strip 30 can be pressed against the surface of the cleaning member 20. When the cleaning member 20 performs a cleaning operation, the scraper strip 30 can scrape off the garbage attached to the surface of the cleaning member 20 for absorption and collection by other dust suction structures, thereby improving the cleaning effect and cleaning efficiency of the cleaning member 20.

[0049] That is to say, the cleaning component in this embodiment drives the scraper bar 30 to switch between the first position and the second position by setting a driving component, so that the scraper bar 30 of the cleaning component can be pressed against the surface of the cleaning member 20 or away from the surface of the cleaning member 20 at an appropriate time. In this way, not only the service life of the cleaning member 20 can be improved, but also the cleaning efficiency and cleaning effect of the cleaning component during the cleaning process can be guaranteed.

[0050] For example, the cleaning assembly in this embodiment can be a floor brush assembly, a table brush assembly, or a cleaning assembly for a sweeper, etc. The cleaning member 20 includes a roller brush, which mainly includes a roller 21 and a mop 22 wrapped around the outside of the roller, and the mop 22 is provided with fluff, etc. The roller 21 rotates around its own axis to drive the mop to wipe and clean the floor or table.

[0051] In this embodiment, the driving component further includes a flexible pulling member 43, which is connected between the scraper bar 30 and the driving mechanism 41. The driving mechanism 41 drives the flexible pulling member 43 to extend or shorten. It can be understood that the extension or shortening of the flexible pulling member 43 mentioned here refers to the lengthening or shortening of the distance between the end of the flexible pulling member 43 close to the scraper bar 30 and the side of the driving component. Specifically, when the driving mechanism 41 drives the flexible pulling member 43 to shorten, the flexible pulling member 43 can drive the scraper bar 30 to switch from the second position to the first position, and the scraper bar 30 is away from the surface of the cleaning member 20. At this time, the cleaning member 20 rotates around its own axis, which is convenient for performing the self-cleaning or dry suction operation of the cleaning member 20. When the driving mechanism 41 drives the flexible pulling member 43 to extend, the elastic element 42 applies an external force to the cleaning member 20, which can drive the scraper bar 30 to switch from the first position to the second position. The scraper bar 30 can be pressed against the surface of the cleaning member 20. At this time, the cleaning member 20 rotates around its own axis to perform the cleaning operation, and the scraper bar 30 can scrape off the garbage attached to the cleaning member 20.

[0052] Combination Figures 2 to 4 As shown, the driving mechanism 41 in this embodiment includes a motor 411 and a wheel hub (not shown in the figure). During actual installation, the motor 411 is installed on the main body 10, and the wheel hub is sleeved on the output shaft of the motor 411. One end of the flexible pulling member 43 is wound around the wheel hub, and the other end is connected to the scraper 30. In this way, when the motor 411 rotates forwards and backwards, it can drive the flexible pulling member 43 to be wound around the wheel hub or released from the wheel hub. In this process, under the action of the elastic element 42, the flexible pulling member 43 can be extended or shortened relative to the motor 411, thereby facilitating the scraper 30 to switch between the first position and the second position. The structure is simple and easy to control.

[0053] Of course, in other embodiments of the present application, the driving mechanism 41 can also be a driving cylinder, which can be extended and retracted to facilitate the flexible pulling member 43 to be extended and retracted. As long as it is other deformation methods based on the conception of the present application, it is within the protection scope of the present application.

[0054] Further, the flexible pulling member 43 in this embodiment includes a pull rope, which can be a nylon, silicone or rubber pull rope. The main body 10 has a first chamber 11 and a second chamber 12 that are isolated from each other, the cleaning member 20 and the scraper 30 are both located in the first chamber 11, the motor 411 is located in the second chamber 12, and the flexible pulling member 43 is arranged between the first chamber 11 and the second chamber 12. In other words, the cleaning member 20 and the scraper 30 and the motor 411 in this embodiment are respectively located in the first chamber 11 and the second chamber 12 that are isolated from each other. In this way, when the cleaning member 20 is working, especially when the cleaning member 20 performs self-cleaning (the cleaning member 20 rotates in the cleaning tank) or performs wet cleaning (the cleaning member 20 rotates and cleans while spraying water to the cleaning member 20), the liquid inside the first chamber 11 is not easy to enter the second chamber 12, and will not cause adverse effects on electrical components such as the motor 411, which can improve the safety and reliability of the cleaning assembly in this embodiment.

[0055] Specifically, a partition 13 is provided between the first chamber 11 and the second chamber 12 of the present application, and a through hole 131 is provided on the partition 13. A flexible conduit 50 is passed through the through hole 131, and the flexible pulling member 43 is passed through the flexible conduit 50. In this way, the flexible pulling member 43 can move relative to the flexible conduit 50 during the process of extending or shortening, and the flexible pulling member 43 will not have stress concentration at the through hole 131 of the partition 13, so that the flexible pulling member 43 is prevented from being worn and broken at the through hole 131, and the reliability of the cleaning component in this embodiment can be improved.

[0056] For example, the flexible conduit 50 in this embodiment can be a rubber tube, or a silicone tube, etc. In this embodiment, the flexible conduit 50 has a certain extension length, so that after the flexible pulling member 43 is inserted into the flexible conduit 50, the flexible conduit 50 can play a certain protective role on the flexible pulling member 43, and can prevent water from wetting the flexible pulling member 43 to a certain extent and bringing water from the first chamber 11 into the second chamber 12, which can further ensure the operation stability of the motor 411.

[0057] Furthermore, a sealing block 51 is provided on the flexible conduit 50 in this embodiment, and the flexible conduit 50 is fixed to the through hole 131 through the sealing block 51. The sealing block 51 in this embodiment can be a structure such as a silicone block or a rubber block. Through the function of the sealing block 51, it is not only convenient to fix the flexible conduit 50 at the through hole 131, but also convenient to seal the gap between the flexible conduit 50 and the through hole 131, which can prevent water in the first chamber 11 from entering the second chamber 12 to a certain extent.

[0058] See also Figure 3 and Figure 4As shown, the cleaning assembly in this embodiment also includes a water spray component 60, which is rotatably mounted on the main body 10 and located outside the cleaning member 20, the scraper strip 30 is fixed on the water spray component 60, and the elastic element 42 is pressed between the main body 10 and the water spray component 60. Among them, the water spray component 60 is provided with a water inlet hole (not shown in the figure) and a water spray plate 61, and a guide groove (not shown in the figure) is arranged inside the water spray plate 61. The water inlet hole is connected with the guide groove. The length direction of the water spray plate 61 is parallel to the axial direction of the cleaning member 20. The water spray plate 61 is provided with a plurality of water spray holes facing the cleaning member 20, and the plurality of water spray holes are arranged at intervals along the length direction of the cleaning member 20 and connected with the guide groove. In this way, when the water inlet hole is connected with other water sources, water can enter the guide groove and can be sprayed from the water spray hole toward the surface of the cleaning member 20. When the cleaning member 20 rotates, the cleaning effect of the cleaning member 20 on the ground or the table can be improved.

[0059] At the same time, in this embodiment, the scraper strip 30 is fixed on the water spray component 60, and the elastic element 42 is pressed between the main body 10 and the water spray component 60. In this way, when the driving motor 411 drives the flexible pulling member 43 to extend and is in a relaxed state, the elastic element 42 applies an external force to the water spray component 60, which can drive the water spray component 60 to move in a direction close to the cleaning component 20, and then drive the scraper strip 30 to press against the cleaning component 20. The structure is simple and easy to implement.

[0060] Specifically, the main body 10 in this embodiment is provided with a rotating shaft 80 that can rotate around its own axis. When actually installed, the water spray component 60 is fixedly installed on the rotating shaft 80, so that when the rotating shaft 80 rotates relative to the main body 10, the water spray component 60 can be driven to rotate synchronously; and the elastic element 42 includes a torsion spring, which is sleeved on the rotating shaft 80, and one end of the torsion spring abuts against the water spray component 60, and the other end abuts against the main body 10. In this embodiment, by setting the rotating shaft 80, and correspondingly setting the elastic element 42 as a torsion spring, the torsion spring is sleeved on the rotating shaft 80, the structure is stable and reliable, and the installation is convenient. In the actual use process, when the driving motor 411 drives the flexible pulling member 43 to extend and is in a relaxed state, the water spray component 60 and the scraper strip 30 installed on the water spray component 60 can be pressed against the cleaning member 20 under the action of the torsion spring, so that the garbage attached to the cleaning member 20 can be scraped off during the rotation of the cleaning member 20, and the structure is simple, stable and reliable.

[0061] Optionally, the torsion spring in this embodiment may be provided as one, or may be provided as two or more.

[0062] Of course, in other embodiments of the present application, the elastic element 42 can also be configured as a spring or other structure. As long as it is other deformation methods based on the concept of the present application, it is within the protection scope of the present application.

[0063] Furthermore, in other embodiments of the present application, the rotating shaft 80 can also be a fixed shaft, and the water spray component 60 is configured as a structure that can rotate around the rotating shaft 80. As long as it is other deformation methods conceived under the present application, it is within the protection scope of the present application.

[0064] During actual installation, the scraper bar 30 is set at the bottom of the water spray component 60, and the cleaning component also includes a sealing baffle 70, which is installed on the main body 10 and located at the bottom of the scraper bar 30, and the end of the sealing baffle 70 has an elastic sealing portion 71 that presses against the bottom of the scraper bar 30. Through the action of the elastic sealing portion 71, garbage can be prevented from entering from the bottom of the scraper bar 30 to the side of the water spray component 60 away from the cleaning component 20, causing inconvenience in cleaning.

[0065] For example, the elastic sealing portion 71 at the end of the sealing baffle 70 in this embodiment can be a rubber sheet or a silicone sheet. After assembly, the elastic sealing portion 71 is tilted toward the direction close to the scraper bar 30 and can interfere with the bottom of the scraper bar 30, that is, the elastic sealing portion 71 can abut against the bottom of the scraper bar 30, thereby preventing water or garbage from entering from the bottom of the scraper bar 30 to the side of the water spray component 60 away from the cleaning member 20.

[0066] Furthermore, a suction channel 90 is also provided on the main body 10 in this embodiment, and the suction channel 90 is located on the side of the cleaning member 20. After the scraper bar 30 scrapes off the garbage attached to the cleaning member 20, the vacuum device carried by the main body 10 or an external vacuum device can suck the garbage from the suction channel to the dust box equipped on the main body 10 or other structures, thereby realizing the collection of garbage on the ground or the table.

[0067] On the other hand, see Figures 1 to 7 As shown, the present application also provides a control method for a cleaning device, which is executed by the cleaning device in the above embodiment. Specifically, the cleaning device in this embodiment includes at least one working mode, and each working mode includes at least one working stage.

[0068] Exemplarily, the cleaning device in this embodiment includes at least one of a floor scrubbing mode, a self-cleaning mode, a water suction mode, and a dry suction mode.

[0069] It can be understood that the floor scrubbing mode in this embodiment refers to a working mode in which the cleaning element 20 of the cleaning device rotates around its own axis to clean the floor or table top, and the water spraying component 60 synchronously sprays water onto the surface of the cleaning element 20; the self-cleaning mode refers to a working mode in which the cleaning element 20 rotates or soaks in a predetermined cleaning tank, or the floor or table top rotates to clean up the garbage attached to the cleaning element 20; the water absorption mode refers to a working mode in which the cleaning element 20 absorbs water from the cleaning tank, floor or table top, etc. on the cleaning element 20; the dry absorption mode refers to a working mode in which the cleaning element 20 cleans the floor or table top, and the water spraying component 60 does not spray water onto the surface of the cleaning element 20.

[0070] When the cleaning device is actually controlled, when the cleaning device switches between different working modes or between different working stages of the same working mode, the driving component is controlled to drive the scraper bar 30 to press against the surface of the cleaning member 20 or to drive the scraper bar 30 away from the surface of the cleaning member 20.

[0071] That is to say, when the cleaning device is working in different modes or in different working stages of the same working mode, the driving component can be controlled, and then the scraper strip 30 can be driven to press against the surface of the cleaning member 20 or move away from the surface of the cleaning member 20, so that the garbage attached to the cleaning member 20 can be processed at the appropriate time, and the cleaning member 20 can be protected at the appropriate time, ultimately achieving the purpose of improving the self-cleaning effect or service life of the cleaning member 20.

[0072] Specifically, the control method of the cleaning device in this embodiment includes the following steps:

[0073] (1) When the cleaning device is switched to the scrubbing mode, the driving component is controlled to drive the scraper bar 30 to abut against the surface of the cleaning member 20 .

[0074] In this step, when the cleaning device switches from other modes to the floor scrubbing mode, the driving component can be controlled by a controller provided on the cleaning device or on other mobile devices, specifically, the motor 411 is controlled to rotate and release the flexible pulling member 43. At this time, the elastic element 42 applies a torque to the water spraying member 60, driving the scraper bar 30 installed on the water spraying member 60 to move toward the direction close to the cleaning member 20 and abut against the surface of the cleaning member 20. In this way, when the cleaning member 20 rotates, the scraper bar 30 can scrape off the garbage attached to the surface of the cleaning member 20, so that the suction component can suck the garbage from the suction channel 90 to a collection device such as a dust box.

[0075] In this embodiment, the timing of controlling the scraper bar 30 to abut against the surface of the cleaning member 20 is: when the controller controls the cleaning member 20 to rotate around its own axis, the driving component is controlled to drive the scraper bar 30 to synchronously abut against the surface of the cleaning member 20. That is to say, when the cleaning device is in the floor scrubbing mode, the scraper bar 30 is controlled to abut against the surface of the cleaning member 20 when the cleaning member 20 starts to rotate, so as to scrape away the garbage attached to the surface of the cleaning member 20 in real time. Of course, in other embodiments of the present application, the timing of controlling the scraper bar 30 to abut against the surface of the cleaning member 20 can also be: after the cleaning member 20 is controlled to rotate around its own axis for a first predetermined time, the driving component is controlled to drive the scraper bar 30 to abut against the surface of the cleaning member 20. That is to say, when the cleaning device is in the floor scrubbing mode, the cleaning member 20 can be controlled to rotate for a period of time, and then the driving component is controlled to drive the scraper bar 30 to abut against the surface of the cleaning member 20 to scrape away the garbage attached to the surface of the cleaning member 20. The time can be 1 minute, 2 minutes, 3 minutes or 5 minutes, etc., and can be selected and designed in combination with the usage scenario of the cleaning device. No specific limitation is made in this application.

[0076] In this embodiment, the driving component is controlled to drive the scraper 30 away from the surface of the cleaning member 20, and the cleaning member 20 is controlled to rotate around its own axis while the water spraying component 60 is used to spray water to the cleaning member 20. In this way, the floor washing effect of the cleaning member 20 in this embodiment can be improved.

[0077] (2) When the cleaning device is switched to the water absorption mode, the driving component is controlled to drive the scraper bar 30 away from the surface of the cleaning member 20 .

[0078] When the cleaning device is switched to the water absorption mode, the driving component can be controlled by a controller provided on the cleaning device or on other mobile devices, specifically, the motor 411 is controlled to rotate to tighten the flexible pulling member 43, and the water spraying member 60 is rotated to compress the elastic element 42, so as to drive the scraper bar 30 installed on the water spraying member 60 away from the surface of the cleaning member 20. In this way, the scraper bar 30 can be prevented from scraping off the water absorbed by the cleaning member 20, and the water absorption performance of the cleaning member 20 can be ensured.

[0079] Optionally, the water absorption mode in the present application can be performed in a cleaning tank filled with water, or on a floor or table with water. When the water absorption mode is performed in a cleaning tank filled with water, it is convenient to absorb the water in the cleaning tank; when the water absorption mode is performed on the floor or table, it is convenient to absorb the water on the floor or table, which can meet the work requirements in different situations.

[0080] (3) When the cleaning device is switched to the dry suction mode, the driving component is controlled to drive the scraper bar 30 away from the surface of the cleaning member 20 .

[0081] When the cleaning device is in the dry suction mode, the step of controlling the driving component to drive the scraper bar 30 away from the surface of the cleaning member 20 is as follows: Figure 6 As shown:

[0082] Step 1: Control the driving component to drive the scraper bar 30 away from the surface of the cleaning member 20. In this step, the driving component can be controlled by a controller provided on the cleaning device or a controller provided on other mobile devices, specifically, the motor 411 is controlled to rotate to tighten the flexible pulling member 43, and the water spraying component 60 is rotated to compress the elastic element 42, so as to drive the scraper bar 30 installed on the water spraying component 60 away from the surface of the cleaning member 20. In other words, when the cleaning device is in the dry suction mode, as long as the cleaning member 20 starts to rotate, the driving component is controlled in real time to drive the scraper bar 30 to synchronously move away from the surface of the cleaning member 20, so that hair and the like can be effectively prevented from being blocked at the contact point between the scraper bar 30 and the cleaning member 20.

[0083] Step 2: Control the cleaning element 20 to rotate about its own axis in a first direction for a first predetermined time;

[0084] Step 3: Control the cleaning member 20 to rotate about its own axis in a second direction opposite to the first direction for a second predetermined time, and then repeat steps 2 to 3 until the cleaning device performs the dry suction mode for a third predetermined time.

[0085] It can be understood that the first direction and the second direction here can be clockwise or counterclockwise. In this embodiment, the cleaning member 20 is controlled to reciprocate along the first direction and the second direction to prevent hair from being entangled on the cleaning member 20.

[0086] The first predetermined time, the second predetermined time and the third predetermined time in this embodiment can be selected and designed according to the actual working conditions of the cleaning device, and are not specifically limited in this application.

[0087] (4) The self-cleaning mode includes at least one of a self-cleaning working stage and a soaking working stage. When the cleaning device switches to the soaking working stage, the driving component is controlled to drive the scraper bar 30 away from the surface of the cleaning member 20. In this step, the driving component can be controlled by a controller provided on the cleaning device or a controller provided on other mobile devices, specifically, the motor 411 is controlled to rotate to tighten the flexible pulling member 43, and the water spraying component 60 is rotated to compress the elastic element 42, so as to drive the scraper bar 30 installed on the water spraying component 60 away from the surface of the cleaning member 20. In this way, it can be avoided that the scraper bar 30 presses against the cleaning member 20 and affects the water absorption of the cleaning member 20, and it is not convenient to soak the garbage attached to the cleaning member 20.

[0088] When the cleaning device switches to the self-cleaning working stage, the driving component is controlled to drive the scraper bar 30 to press against the surface of the cleaning member 20. In this step, the driving component can be controlled by a controller set on the cleaning device or a controller set on other mobile devices, specifically, the motor 411 is controlled to rotate and release the flexible pulling member 43. At this time, the elastic element 42 applies a torque to the water spraying component 60, driving the scraper bar 30 installed on the water spraying component 60 to move toward the direction close to the cleaning member 20 and press against the surface of the cleaning member 20. In this way, when the cleaning member 20 rotates, the scraper bar 30 can scrape off the garbage attached to the surface of the cleaning member 20, so that the suction component can suck the garbage from the suction channel 90 to a collection device such as a dust box.

[0089] Furthermore, when the cleaning device switches to the self-cleaning working stage, the steps of controlling the driving component to drive the scraper strip 30 to abut against the surface of the cleaning member 20 are as follows:

[0090] (a) Control the driving component to drive the scraper bar 30 to abut against the surface of the cleaning member 20, and control the cleaning member 20 to rotate counterclockwise or clockwise around its own axis for a fourth predetermined time. That is to say, when the cleaning device switches to the self-cleaning working stage, only the cleaning member 20 is driven to rotate counterclockwise or clockwise around its own axis and the scraper bar 30 is used to scrape away the garbage attached to the cleaning member 20. The fourth predetermined time can be designed and selected according to actual needs, and is not specifically limited in this application.

[0091] (b) If Figure 7 As shown, step S1: control the driving component to drive the scraper 30 to press against the surface of the cleaning member 20; step S2: control the cleaning member 20 to rotate around its own axis in a first direction for a fifth predetermined time; step S3: control the cleaning member 20 to rotate around its own axis in a second direction opposite to the first direction for a sixth predetermined time; then repeat steps S2 and S3 until the cleaning member 20 performs the self-cleaning work stage for the seventh predetermined time.

[0092] It is understandable that the first direction and the second direction here can be counterclockwise or clockwise. When the first direction is clockwise, the second direction is counterclockwise; when the first direction is counterclockwise, the second direction is clockwise. That is to say, when the cleaning member 20 switches to the self-cleaning working stage, the cleaning member 20 can be rotated back and forth in the counterclockwise or clockwise direction until the predetermined time is reached, so that the self-cleaning efficiency of the cleaning member 20 can be improved.

[0093] Exemplarily, the fifth scheduled time and the sixth scheduled time in this embodiment can be 10 seconds, 20 seconds or 30 seconds, etc., and the seventh scheduled time can be 3 minutes, 4 minutes or 5 minutes, etc., which are selected and designed according to actual needs and are not specifically limited in this application.

[0094] According to the control method of the cleaning device mentioned above, it can be known that the control method of the cleaning device of the present application can switch the cleaning device to at least one working mode among the floor washing mode, self-cleaning mode, water suction mode and dry suction mode, or switch the scraper bar in different working stages of the self-cleaning mode, so that the scraper bar can touch or stay away from the cleaning part at the right time, which can not only protect the cleaning part, but also ensure the water absorption of the cleaning part, and can improve the self-cleaning efficiency and service life of the cleaning device.

[0095] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0096] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0097] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
