Description
Technical Field
[0001] This application relates to the field of cleaning equipment technology, specifically to a liftable disc brush assembly, and also to a cleaning device equipped with the aforementioned liftable disc brush assembly. Background Technology
[0002] With the development of technology and the improvement of people's living standards, cleaning robots are increasingly being used in people's lives. Among them, disc brush cleaning robots can sweep up sticky or heavy debris from the ground using rotating disc brushes. Because disc brushes usually have greater cleaning power, the cleaning effect is better.
[0003] However, when cleaning robots that have already completed their cleaning tasks arrive at designated locations such as base stations, where the ground is not very dirty but only has some light debris, existing disc brush cleaning robots will keep the disc brush in constant contact with the ground during operation. This means that the sewage or small debris stuck to the disc brush may dirty the already cleaned ground again. In addition, because the disc brush has a relatively strong cleaning power, it may not be necessary to clean the ground if there is only light debris. In this case, since the disc brush is always in contact with the ground, it may cause wear and tear on the ground, affecting the user experience. Summary of the Invention
[0004] This application provides a liftable disc brush assembly and a cleaning device. It enables both raising and lowering of the disc brush, as well as rotating it for cleaning. This allows the disc brush to be raised away from the surface to be cleaned when not in use, and lowered to contact the surface when needed, thus improving the user experience.
[0005] The specific plan is as follows:
[0006] In a first aspect, this application provides a liftable disc brush assembly, comprising:
[0007] A rotating structure for outputting rotational torque;
[0008] A rotary lifting structure is connected to the rotary structure via a sliding groove and slider structure. The rotary lifting structure is used to rotate or lift under the rotation of the rotary structure via the sliding groove and slider structure. The sliding groove in the sliding groove and slider structure is inclined downward along the lifting direction of the rotary lifting structure.
[0009] A disc brush is installed on the rotating and lifting structure;
[0010] The rotating structure has two opposite rotation directions: a first direction and a second direction. Rotating in the first direction causes the slider to slide upwards within the groove, raising the rotating lifting structure and disengaging the disc brush from the surface to be cleaned. Rotating in the second direction causes the slider to slide downwards within the groove, reaching a position where the disc brush contacts the surface to be cleaned. When the disc brush contacts the surface, the slider abuts against the end wall of the groove and stops sliding within it. Under the rotational force of the rotating structure, the slider and the end wall continue to rotate, causing the rotating lifting structure to rotate and thus rotating the disc brush, cleaning the surface.
[0011] Secondly, this application provides a cleaning device, including a mounting frame on which a liftable disc brush assembly as described in any one of the first aspects is disposed;
[0012] The adjustable disc brush assembly has a disc brush that contacts the surface to be cleaned in the lowered state and cleans it by rotating relative to the surface. In the raised state, it disengages from the surface to be cleaned.
[0013] Compared with the prior art, this application has the following advantages:
[0014] The rotating structure of the liftable disc brush assembly provided in this application can output rotational torque. The rotating lifting structure is connected to the rotating structure through a sliding block structure that cooperates with each other. When the rotating structure rotates, it can drive the slider to slide in the sliding block. Since the sliding block is inclined downward along the lifting direction of the rotating lifting structure, when the rotating structure rotates in the first direction, the sliding block on the rotating structure will rotate along the first direction with the rotating structure. The slider on the rotating lifting structure will slide upward as a whole under the guidance of the inclined downward sliding block, thereby driving the rotating lifting structure to rise. Since the disc brush is mounted on the rotating lifting structure, it can drive the disc brush to rise, so that the disc brush is separated from the surface to be cleaned. When the rotating structure rotates in the second direction opposite to the first direction, the sliding block on the rotating structure will rotate along the second direction with the rotating structure. The slider on the rotating lifting structure will slide downward as a whole under the guidance of the inclined downward sliding block, thereby driving the rotating lifting structure to fall, so that the disc brush falls to the position of contacting the surface to be cleaned. When the disc brush contacts the surface to be cleaned, the slider slides relative to the chute until it abuts against the end wall of the chute. At this point, the slider is blocked by the end wall of the chute and stops sliding. Then, the rotating structure continues to rotate in the second direction, which can drive the slider set on the rotating lifting structure to rotate under the opposing force between the slider and the end wall, thereby driving the rotating lifting structure to rotate, so that the disc brush can rotate and clean the surface to be cleaned.
[0015] The adjustable disc brush assembly provided in this application allows the disc brush to be raised and lowered. When the user needs to use the disc brush, the disc brush can be lowered to contact the surface to be cleaned for cleaning. When the user does not need to use the disc brush, the disc brush can be raised to lift it off the ground, allowing the user to use it flexibly according to their needs and improving the user experience.
[0016] In addition, the embodiments of this application use a sliding block structure, which enables the rotating structure to both lift and rotate the disc brush, eliminating the need for separate rotation output and lifting drive structures. The structure is simple, compact, and easy to implement. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solutions of this application, the application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. However, this application can be implemented in many other ways different from those described below. Therefore, based on the embodiments provided in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.
[0026] It should be noted that the terms "first," "second," "third," etc., in the claims, specification, and drawings of this application are used to distinguish similar objects and are not used to describe a specific order or sequence. Such data are interchangeable where appropriate so that the embodiments of this application described herein can be implemented in a sequence other than that shown or described herein. Furthermore, the terms "comprising," "having," and their variations are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or apparatuses.
[0027] With the development of technology and the improvement of people's living standards, cleaning robots are increasingly being used in people's lives. Cleaning robots mainly include roller brush cleaning robots and disc brush cleaning robots. Roller brush cleaning robots use a roller brush with bristles around its circumference to sweep garbage and wastewater from the ground into a dust collection box located behind the brush, thus achieving the purpose of cleaning. However, when there is stubborn garbage on the ground, such as debris stuck to the ground or heavy garbage, the roller brush may not be able to sweep it up, and therefore cannot sweep it into the dust collection box, resulting in incomplete cleaning, a large amount of residual garbage, and poor cleaning effect.
[0028] To clean up sticky or heavy debris from the ground, you can use a disc brush cleaning robot. Disc brush cleaning robots use rotating disc brushes to sweep up sticky or heavy debris from the ground. Since the disc brush usually has a greater cleaning power, the cleaning effect is better. Then, use a vacuum cleaner to suck the swept debris into the dust collection box.
[0029] However, when cleaning robots that have already completed their cleaning tasks arrive at designated locations such as base stations, where the ground is not very dirty but only has some light debris, existing disc brush cleaning robots will keep the disc brush in constant contact with the ground during operation. This means that the sewage or small debris stuck to the disc brush may dirty the already cleaned ground again. In addition, because the disc brush has a relatively strong cleaning power, it may not be necessary to clean the ground if there is only light debris. In this case, since the disc brush is always in contact with the ground, it may cause wear and tear on the ground, affecting the user experience.
[0030] To address the above issues, the first embodiment of this application provides a liftable disc brush assembly that enables both lifting and rotating of the disc brush for cleaning. This allows the disc brush to be raised away from the surface to be cleaned when not in use, and lowered to contact the surface when needed, thus improving the user experience.
[0031] like Figures 1 to 5 As shown, the liftable disc brush assembly provided in this application embodiment includes: a rotating structure 620, a rotating lifting structure 610, and a disc brush 200.
[0032] The rotating structure 620 is used to output rotational torque. The rotating lifting structure 610 and the rotating structure 620 are connected by a cooperating sliding block structure. The rotating lifting structure 610 is used to rotate or lift under the influence of the rotation of the rotating structure 620 via the sliding block structure. The sliding block structure has a sliding groove 630 that is inclined downwards along the lifting direction of the rotating lifting structure 610. The disc brush 200 is mounted on the rotating lifting structure 610.
[0033] The rotating structure 620 has two opposite rotational directions, a first direction and a second direction. Rotating along the first direction, the rotating structure 620 drives the slider 640 to slide upwards within the groove 630, causing the rotating lifting structure 610 to rise and disengage the disc brush 200 from the surface to be cleaned. Rotating along the second direction, the rotating structure 620 drives the slider 640 to slide downwards within the groove 630, reaching a position where the disc brush 200 contacts the surface to be cleaned. When the disc brush 200 contacts the surface, the slider 640 slides down to abut against the end wall of the groove 630 and stops sliding within it. Continuing to rotate along the second direction, the rotating structure 620, through the force of the slider 640 against the end wall, drives the rotating lifting structure 610 to rotate, causing the disc brush 200 to rotate and clean the surface.
[0034] The aforementioned rotating structure 620 can be a shaft, turntable, drum, or other rotatable structure; this application does not specifically limit its application. When using the liftable brush assembly provided in this application, the output shaft of the drive mechanism 500, such as a rotary motor, can be connected to the rotating structure 620 to drive its rotation. The rotating lifting structure 610 can be a shaft, drum, turntable, or other rotatable structure; this application does not specifically limit its application.
[0035] The rotary lifting structure 610 and the rotary structure 620 are connected by a sliding groove and slider structure that cooperates with each other. The rotary structure 620 can be provided with a downward inclined sliding groove 630, and the rotary lifting structure 610 can be provided with a slider 640 inserted into the sliding groove 630. The sliding of the slider 640 can more reliably drive the rotary lifting structure 610 to move up and down, making the structure of the liftable disc brush assembly more reliable and reasonable, and improving the structural stability.
[0036] When a groove 630 is provided on the rotating structure 620 and a slider 640 is provided on the rotating lifting structure 610, the rotation of the rotating structure 620 in the second direction will cause the slider 640 to slide within the groove 630. When the slider 640 slides to abut against the lower end wall of the groove 630, it stops sliding. At this time, since the slider 640 is set on the rotating lifting structure 610, the slider 640 drives the rotating lifting structure 610 to move to the lowest position (i.e., the position where the disc brush 200 contacts the surface to be cleaned). When the slider 640 moves to abut against the lower end wall of the groove 630, it can no longer slide. Therefore, when the rotating structure 620 continues to rotate in the second direction, the slider 640, which is stuck in the groove 630 and cannot slide down further, will rotate with the rotating structure 620, thereby driving the rotating lifting structure 610 to rotate as well, so that the disc brush 200 installed on the rotating lifting structure 610 can also rotate for cleaning. Then, the rotating mechanism is rotated in the opposite direction along the first direction. Based on the same principle, the rotating lifting mechanism can be raised until the disc brush 200 is detached from the surface to be cleaned. In this embodiment, the rotation of the rotating structure 620 along the first direction can be stopped when the slider 640 abuts against the upper wall of the slide groove 630 to save energy and avoid idling. Alternatively, the rotation of the rotating structure 620 can be maintained when the slider 640 abuts against the upper wall of the slide groove 630. This application does not specifically limit this.
[0037] In this embodiment of the application, when the disc brush 200 contacts or leaves the surface to be cleaned, it means that the bristles 210 of the disc brush 200 contact or leave the surface to be cleaned.
[0038] The disc brush 200 can be installed at the lower end of the rotating lifting structure 610 so that the disc brush 200 can contact the surface to be cleaned after it descends.
[0039] In one embodiment, the rotating structure 620 can be a cylindrical rotating body, and the rotating lifting structure 610 can be a rotating lifting outer sleeve fitted outside the rotating structure 620. The rotating lifting outer sleeve is loosely fitted outside the rotating structure 620 so that the rotating lifting outer sleeve can rotate and move axially relative to the rotating structure 620. In this case, such as Figure 3 , Figure 4 As shown, the aforementioned groove 630 can be provided on the outer wall of the cylindrical rotating body, and the corresponding slider 640 can be provided on the inner wall of the rotating lifting outer sleeve, which makes it easier to install the rotating lifting outer sleeve.
[0040] When a groove 630 is provided on the outer wall of the cylindrical rotating body, multiple grooves 630 can be evenly distributed along the circumference of the rotating inner sleeve. Multiple sliders 640 corresponding to and cooperating with the multiple grooves 630 can be provided on the rotating lifting outer sleeve. In this way, the rotating structure 620 can apply a more uniform external force to the circumference of the rotating lifting outer sleeve when rotating, thereby improving the smoothness and reliability of the lifting and rotating operation of the disc brush 200 of the disc brush assembly.
[0041] In another embodiment, the rotating structure 620 can also be a rotating sleeve, and the rotating lifting structure 610 can be a rotating lifting cylinder loosely fitted inside the rotating sleeve. This method can also achieve the function of driving the rotating lifting cylinder to lift and rotate when the rotating sleeve rotates. In this case, the aforementioned groove 630 can be provided on the inner side wall of the rotating sleeve, and the aforementioned sliding block 640 can be provided on the outer wall of the rotating lifting cylinder.
[0042] The two embodiments described above, through the nested rotating structure 620 and rotating lifting structure 610, can make the structure more compact and the connection more stable and reliable. The rotating lifting structure 610 can also rotate around its own rotation center under the drive of the rotating structure 620, so that the disc brush 200 can achieve cleaning by rotating around its own rotation center.
[0043] In one embodiment, the liftable disc brush assembly may further include a mounting base 100, the rotating structure 620 being horizontally rotatably mounted on the mounting base 100, and the rotating lifting structure 610 being slidably connected to the mounting base 100 along the lifting direction of the rotating lifting structure 610 and being horizontally rotatably arranged relative to the mounting base 100.
[0044] The aforementioned mounting base 100 can be a frame structure, a plate structure, a rod structure, or other regular or irregular shape structure. The mounting base 100 only needs to meet the requirements for installing the rotating structure 620 and the rotating lifting structure 610, and the specific structure is not limited.
[0045] In this embodiment, the horizontal direction is relative to the lifting direction of the rotary lifting structure 610, that is, the horizontal direction is perpendicular to the lifting direction of the rotary lifting structure 610. The above-mentioned horizontal rotation refers to the horizontal plane of rotation, which means that the central axis of rotation is parallel to the lifting direction of the rotary lifting structure 610.
[0046] In one specific embodiment, a drive shaft 650 can be horizontally rotatably mounted on the mounting base 100. The drive shaft 650 can be mounted on the mounting base 100 via a rotating bearing 1200 to achieve horizontal rotation of the drive shaft 650 relative to the mounting base 100. The drive shaft 650 can be concentrically connected to the rotating structure 620 to drive the rotating structure 620 to rotate. In practical applications, the output shaft of the drive motor can be connected to the drive shaft 650 via a reduction gearbox 1000, a gear mechanism, a linkage mechanism, etc., thereby driving the drive shaft 650 to rotate horizontally. This method of concentrically connecting the drive shaft 650 and the rotating structure 620 in this embodiment makes it easier for the drive motor to drive the rotating structure 620 to rotate, and makes subsequent installation of the liftable disc brush assembly on the cleaning device more convenient, resulting in a more compact and reasonable structure.
[0047] Optionally, the drive shaft 650 and the rotating structure 620 are concentrically connected. The rotating structure 620 can be configured as a sleeve structure, concentrically fixed around the drive shaft 650. In other words, the rotating structure 620 is a rotating inner sleeve, fixedly fitted around the drive shaft 650, rotating under the influence of the drive shaft 650's rotation. The rotating inner sleeve can be fixed around the drive shaft 650 via an interference fit, or the relative position can be fixed through a key connection, pin connection, or other methods. This application does not specifically limit this. This sleeve configuration in this embodiment ensures a reliable fixed connection between the drive shaft 650 and the rotating structure 620, and also makes the connection between components more compact, improving the structural compactness and reliability of the disc brush assembly. To make the axial positioning between the rotating inner sleeve and the drive shaft 650 more reliable, such as... Figure 1 , Figure 2 , Figure 5 As shown, a fastening screw 1100 can be screwed into the end of the drive shaft 650, and the screw head of the fastening screw 1100 simultaneously abuts against the end face of the rotating inner sleeve and the end face of the drive shaft 650.
[0048] For example, such as Figure 1 , Figure 2 , Figure 5As shown, a cylindrical inner sleeve insert 660 can be fixed inside the rotating inner sleeve. The inner sleeve insert 660 is inserted and fixed to the rotating inner sleeve, and is interference-fitted onto the outside of the drive shaft 650. The rotating inner sleeve is fixed to the outside of the drive shaft 650 by the inner sleeve insert 660. The material hardness of the inner sleeve insert 660 is greater than that of the rotating inner sleeve. Because the material hardness of the inner sleeve insert 660 is greater, the interference fit between the inner sleeve insert 660 and the drive shaft 650 can better avoid surface damage to the material, resulting in better connection stability of the rotating inner sleeve when fixedly fitted with the drive shaft 650, thereby improving the structural stability of the disc brush assembly.
[0049] Optionally, the drive shaft 650 and the rotating structure 620 can be concentrically connected. Alternatively, one end of the rotating structure 620 can be concentrically fixed to one end of the drive shaft 650 to achieve the concentric connection. For example, a flange structure or coupling can be used to concentrically fix one end of the drive shaft 650 to one end of the rotating structure 620 so that the rotating structure 620 can rotate synchronously under the drive of the drive shaft 650.
[0050] In another specific embodiment, a rotating bearing can be fitted over the rotating structure 620 and mounted on the mounting base 100. In this case, the rotating lifting structure 610 can be fitted inside the rotating structure 620, and the drive motor can be connected to the rotating structure 620 via a gear mechanism, cam mechanism, linkage mechanism, etc., to drive the rotating mechanism to rotate horizontally. This method can also achieve the rotation of the rotating structure 620 relative to the mounting base 100.
[0051] The rotating structure 620 of the liftable disc brush assembly provided in this application can output rotational torque. The rotating lifting structure 610 and the rotating structure 620 are connected by a sliding block structure that cooperates with each other. When the rotating structure 620 rotates, it can drive the slider 640 to slide in the sliding block 630. Since the sliding block 630 is inclined downward along the lifting direction of the rotating lifting structure 610, when the rotating structure 620 rotates in the first direction, the sliding block 630 on the rotating structure 620 will rotate along the first direction with the rotating structure 620. The slider 640 on the rotating lifting structure 610 will slide upward as a whole under the guidance of the inclined downward sliding block 630, thereby driving the rotating lifting structure 610 to rise and fall. Since the disc brush 200 is installed on the rotating lifting structure 610, it can drive the disc brush 200 to rise, so that the disc brush 200 is detached from the surface to be cleaned. The state of the disc brush 200 detached from the surface to be cleaned is as follows. Figure 1As shown. When the rotating structure 620 rotates in a second direction opposite to the first direction, the slide groove 630 provided on the rotating structure 620 will rotate along with the rotating structure 620 in the second direction, while the slider 640 provided on the rotating lifting structure 610 will slide downward as a whole under the guidance of the downwardly inclined slide groove 630, thereby driving the rotating lifting structure 610 to descend, so that the disc brush 200 descends to the position of contacting the surface to be cleaned. The state of the disc brush 200 contacting the surface to be cleaned is as follows. Figure 2 As shown. When the disc brush 200 contacts the surface to be cleaned, the slider 640 slides relative to the groove 630 until it abuts against the end wall of the groove 630. At this time, the slider 640 is blocked by the end wall of the groove 640 and stops sliding. At this time, the rotating structure 620 continues to rotate in the second direction, which can drive the slider 640 set on the rotating lifting structure 610 to rotate under the opposing force between the slider 640 and the end wall, thereby driving the rotating lifting structure 610 to rotate, so that the disc brush 200 rotates to contact the surface to be cleaned for rotational cleaning.
[0052] The disc brush 200 of the liftable disc brush assembly provided in this application can be raised and lowered. Therefore, when the user needs to use the disc brush 200, the disc brush 200 can be lowered to make the disc brush 200 contact the surface to be cleaned for cleaning. When the user does not need to use the disc brush 200, the disc brush 200 can be raised to lift it off the ground, so that the user can use it flexibly according to their own needs and improve the user experience.
[0053] In addition, the embodiments of this application use a sliding block structure, which enables the rotating structure 620 to both lift and rotate the disc brush 200, eliminating the need for separate rotation output structures and lifting drive structures. The structure is simple, compact, and easy to implement.
[0054] In one implementation, such as Figure 1 , Figure 2 , Figure 5 As shown, the mounting base 100 may be provided with a cylindrical mounting sleeve 110 extending along the lifting direction of the rotary lifting structure 610. The rotary lifting outer sleeve is rotatably fitted inside the mounting sleeve 110 and can slide axially relative to the mounting sleeve 110. In this embodiment, the rotary lifting outer sleeve can be loosely fitted inside the mounting sleeve 110, so that the rotary lifting outer sleeve can both rotate relative to the mounting sleeve 110 and slide axially relative to the mounting sleeve 110. In this embodiment, fitting the rotary lifting outer sleeve inside the mounting sleeve 110 can better limit the lifting and rotation of the rotary lifting outer sleeve, making it less likely for the rotary lifting outer sleeve to detach from the mounting base 100, and better enabling the rotary lifting outer sleeve to lift and lower in the set lifting direction (i.e., the axial extension direction of the mounting sleeve 110), making the structure of the disc brush assembly more reliable.
[0055] In one specific embodiment, the frictional resistance between the rotating lifting outer sleeve and the mounting sleeve 110 can be greater than a first preset resistance threshold. The first preset resistance threshold can be set empirically, based on the principle that the slider 640 can slide within the groove 630 without rotating with the rotating inner sleeve when the inner sleeve rotates. When the frictional resistance between the rotating outer sleeve and the mounting sleeve 110 is large, the rotating inner sleeve will not easily cause the rotating lifting outer sleeve to rotate. Thus, when the rotating lifting outer sleeve needs to be raised or lowered, the slider 640 can slide relative to the groove 630 during the rotation of the inner sleeve, allowing the rotating lifting outer sleeve to rise or fall. When the slider 640 abuts against the end wall of the groove 630, the rotating lifting outer sleeve then rotates. This embodiment allows the rotating lifting outer sleeve to drive the disc brush 200 to rise and fall more efficiently and reliably, avoiding jamming or failure to rise and fall smoothly, making the lifting and falling of the disc brush 200 of the liftable disc brush assembly more reliable.
[0056] In this embodiment, since the rotating lifting outer sleeve can rotate and rise relative to the mounting sleeve 110, the frictional resistance between the rotating lifting outer sleeve and the mounting sleeve 110 should not be set too high. That is, the frictional resistance between the rotating lifting outer sleeve and the mounting sleeve 110 can be greater than the first preset resistance threshold and less than the second preset resistance threshold. The second preset resistance threshold is the resistance value that prevents the rotating lifting outer sleeve and the mounting sleeve 110 from moving relative to each other. When the frictional resistance between the rotating lifting outer sleeve and the mounting sleeve 110 is less than the second preset resistance threshold, the rotating lifting outer sleeve can slide downward relative to the mounting sleeve 110 along with the slide groove 630 when the slider 640 slides relative to the slide groove 630. After the slider 640 abuts against the lower end wall of the slide groove 630, it rotates relative to the mounting sleeve 110 under the drive of the rotating inner sleeve, so as not to make the rotating lifting outer sleeve fixed relative to the mounting sleeve 110. This embodiment can smoothly realize the lifting and rotation of the rotating lifting outer sleeve relative to the mounting sleeve 110.
[0057] In one specific embodiment, such as Figure 1 , Figure 2 , Figure 5 As shown, a rubber ring 1300 may be provided between the rotating lifting outer sleeve and the mounting sleeve 110. The rubber ring 1300 is configured to make the frictional resistance between the rotating lifting outer sleeve and the mounting sleeve 110 greater than a first preset resistance threshold.
[0058] Specifically, the rubber ring 1300 can be fixedly fitted around the outer sleeve of the rotating lifting sleeve, and the rubber ring 1300 is in contact with the mounting sleeve 110 by compression. One rubber ring 1300 can be fixedly fitted around the outer sleeve of the rotating lifting sleeve, or two or more rubber rings 1300 can be distributed at intervals along the axial direction, so as to better ensure that the frictional resistance between the rotating lifting sleeve and the mounting sleeve 110 is greater than the first preset resistance threshold.
[0059] In this embodiment, by setting a rubber ring 1300, the frictional resistance between the rotating lifting outer sleeve and the mounting sleeve 110 can be easily increased through a simple structure, so as to achieve the purpose of the frictional resistance being greater than the first preset resistance threshold.
[0060] Alternatively, frictional resistance can be increased by providing other resistance devices between the rotating lifting outer sleeve and the mounting sleeve 110, such as dampers, damping blocks, etc., or by using a transition fit between the rotating lifting outer sleeve and the mounting sleeve 110. This application does not limit the specific way of increasing frictional resistance.
[0061] In one specific embodiment, the slide 630 can be spirally inclined downward along the axial direction of the rotating structure 620. By spirally inclining the slide 630 downward, the slider 640 descends more linearly when the rotating structure 620 rotates, improving the straightness of the lifting and lowering of the rotating lifting structure 610, thereby increasing the lifting efficiency of the disc brush 200.
[0062] In one embodiment, the lower end of the rotating inner sleeve can also be fixedly covered with an inner sleeve end cap 700 to protect the rotating inner sleeve and better prevent garbage, water stains, etc. from entering the rotating inner sleeve and affecting the operational reliability of the rotating inner sleeve.
[0063] Optionally, a notch may be provided on the lower end face of the rotating inner sleeve, and an insertion protrusion 710 may be provided on the inner wall of the inner sleeve end cap 700. The insertion protrusion 710 is inserted into the notch to position the rotating inner sleeve and the inner sleeve end cap 700, making it easier to install and position the inner sleeve end cap 700. In this embodiment, when there is not enough space on the rotating inner sleeve to provide a notch, the notch provided on the rotating inner sleeve can communicate with the slide groove 630. When the insertion protrusion 710 is inserted into the notch, it can form the groove wall of the slide groove 630 at the notch.
[0064] In one embodiment, the disc brush 200 can be attached to the rotating lifting outer sleeve by an electromagnet 810, which makes it easier to install and remove the disc brush 200 and makes it easier to replace the disc brush 200.
[0065] In one embodiment, the lower end of the rotating lifting outer sleeve can also be fixedly covered with an outer sleeve end cap 900 to protect the inside of the rotating lifting outer sleeve and prevent garbage or water stains from entering the rotating lifting outer sleeve or other components and affecting normal operation, thereby improving the operational stability and service life of the disc brush assembly.
[0066] In one embodiment, the magnet 810 can be fixedly installed inside the outer sleeve end cap 900. The disc brush 200 is provided with an iron sheet 820, which is used to attract the magnet 810, thereby fixing the disc brush 200 to the rotating and lifting outer sleeve. Fixing this sheet inside the outer sleeve end cap 900 can provide dust protection for the magnet 810.
[0067] Optionally, a through hole 910 may be provided on the outer sleeve end cap 900 at a position corresponding to the magnet 810. The projection of the through hole 910 is located within the projection of the magnet 810. When the iron sheet 820 is attracted to the magnet 810, the iron sheet 820 covers the through hole 910. In this way, the magnet 810 can more firmly attract the disc brush 200 with the iron sheet 820 through the through hole 910.
[0068] Corresponding to the liftable disc brush assembly provided in the first embodiment, the second embodiment of this application also provides a cleaning device equipped with the liftable disc brush assembly provided in the first embodiment.
[0069] like Figure 5 , Figure 6 As shown, the cleaning device provided in the second embodiment of this application includes a mounting frame 1400, on which a liftable disc brush assembly as described in any one of the first embodiments is provided. When the disc brush 200 of the liftable disc brush assembly is in the descending state, it contacts the surface to be cleaned and cleans it by rotating relative to the surface to be cleaned. When it is in the raised state, it disengages from the surface to be cleaned.
[0070] The mounting bracket 1400 can be a frame, base, or other structure for mounting various components of the cleaning device. The specific structure of the mounting bracket 1400 is not limited. In this embodiment, the user can manually drive the rotating structure 620 of the liftable disc brush assembly to rotate via a handle or similar drive lever, thereby causing the rotating lifting structure 610 to rise or rotate, which in turn drives the disc brush 200 to rise or rotate. The drive handle is connected to the rotating structure 620 in a transmission connection.
[0071] To improve the ease of use and increase the degree of automation of the cleaning device, the cleaning device may also include a drive mechanism 500, which can be a drive motor, a cylinder, a hydraulic cylinder, or other similar drive mechanism. For ease of control, and for ease of use and compact structure, the drive mechanism 500 can be a drive motor. The drive mechanism 500 is mounted on the mounting bracket 1400 and is connected to the rotating structure 620 of the liftable disc brush assembly.
[0072] The aforementioned liftable disc brush assembly has a disc brush 200 that contacts the surface to be cleaned in the descending state and cleans it by rotating relative to the surface. In the raised state, it disengages from the surface to be cleaned. The specific operation process includes: the drive mechanism 500 drives the rotating structure 620 to rotate in a first direction, thereby causing the disc brush 200 to descend to the position where the slider 640 and the end wall of the groove 630 abut against each other and contact the surface to be cleaned by rotating relative to the surface; and the drive mechanism 500 drives the rotating structure 620 to rotate in a second direction opposite to the first direction, thereby causing the disc brush 200 to rise until it disengages from the surface to be cleaned.
[0073] The specific process of raising and lowering the disc brush 200 in this embodiment has been described in detail in the first embodiment, and will not be described in detail here.
[0074] In one embodiment, the mounting bracket 1400 may also be provided with a roller brush 300 and a dust collection container, and the disc brush 200, the roller brush 300 and the dust collection container are arranged sequentially from front to back along the cleaning direction of the cleaning device.
[0075] The aforementioned cleaning device may also include a roller 400 disposed at the front end of the mounting frame 1400, the roller 400 being used to drive the entire cleaning device to perform cleaning.
[0076] During cleaning, the disc brush 200 effectively sweeps up sticky or heavy debris from the surface, while the roller brush 300 rolls the debris into the dust collection container. This method effectively cleans various types of debris without the need for a separate, complex, and expensive vacuum cleaner. The roller brush 300 alone swirls the debris into the dust collection container, resulting in a simpler and more cost-effective cleaning system. Furthermore, when cleaning surfaces with only light debris, the user can raise the disc brush 200 and use the roller brush 300 to clean the floor, increasing flexibility and convenience for the user and enhancing the overall user experience.
[0077] It should be noted that although several structures, components, or units for implementing the relevant functions have been mentioned in the detailed description above, this division is not mandatory. In fact, according to the specific embodiments of this application, the features and functions of two or more structures, components, or units described above can be embodied in one structure, component, or unit. Conversely, the features and functions of one structure, component, or unit described above can be further divided and embodied by multiple components, structures, or units.
[0078] The technical solutions provided in the embodiments of this application will be described in conjunction with specific application scenarios.
[0079] Application scenarios
[0080] The cleaning device includes a mounting bracket 1400 and a liftable disc brush assembly. When the disc brush 200 is needed to clean the surface, such as when there is sticky or heavy debris on the floor, the user can trigger the disc brush cleaning mode by pressing the disc brush cleaning button on the remote control or the control panel. Based on the user's disc brush cleaning mode trigger command, the drive mechanism 500 controls the disc brush 200 of the liftable disc brush assembly to descend to a position in contact with the surface to be cleaned, and continues to rotate the disc brush 200 to clean the surface. When the disc brush 200 is no longer needed, for example, when the cleaning process is completed, when the user triggers a cleaning completion command, or when the user triggers a command to end the disc brush cleaning mode, the disc brush 200 of the liftable disc brush assembly is raised to a position where it is no longer in contact with the surface to be cleaned.
[0081] Furthermore, although the various components of the components or apparatus in this application and the mounting arrangements between them are described in a specific order in the accompanying drawings, this does not require or imply that the components or apparatus must be designed according to that specific component or mounting arrangement, or that all the components shown must be included to achieve the desired result. Additional or alternative components may be omitted, multiple components may be combined into one component to achieve the corresponding function, and / or a component may be decomposed into multiple components to achieve the corresponding function, etc.
[0082] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any modifications, equivalent substitutions, and improvements made by those skilled in the art within the scope of the technology disclosed in this application, and within the spirit and principles of this application, should be included within the scope of protection of this application.
