Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a cleaning chassis and cleaning equipment. Background Technology
[0002] As a type of efficient floor cleaning equipment, some traditional cleaning equipment typically includes a disc brush as its core cleaning component. The disc brush removes stains by rotating and rubbing the floor.
[0003] Traditional cleaning equipment typically uses manual installation for its disc brushes, requiring users to align the brush with the drive shaft and press it in place. This installation method is inconvenient, especially when frequently changing the brush, and its efficiency is low. The installation accuracy and efficiency need improvement, and misalignment can lead to unstable operation, affecting cleaning performance and equipment lifespan. Utility Model Content
[0004] Therefore, it is necessary to provide a chassis cleaning and cleaning equipment to address the above problems.
[0005] A cleaning chassis, comprising:
[0006] Base;
[0007] A lifting assembly, wherein the lifting assembly is disposed on the base;
[0008] A drive assembly, comprising a drive member disposed on the base and a drive head connected to the drive member, the drive head being capable of rotating under the drive of the drive member;
[0009] A disc brush assembly, comprising a bracket, a disc brush disposed below the bracket, and a connector disposed on the bracket, wherein the bracket has a mounting groove, and a drive head can extend into the mounting groove under the drive of a lifting assembly, and the drive head is relatively fixed to the connector; and
[0010] A positioning component is disposed on the base, and the positioning component is capable of restricting the radial movement of the disc brush assembly so that the drive head can be aligned with the mounting slot.
[0011] The aforementioned cleaning chassis has at least the following beneficial effects: the cleaning chassis uses a lifting component to drive the drive head down and insert it into the mounting slot for fixation, thereby realizing the automatic installation and removal of the disc brush. The operation is convenient and the connection is stable, avoiding the alignment difficulties and loosening problems of traditional manual installation methods. At the same time, the structure is simple and reliable, with high installation efficiency, significantly improving the user experience.
[0012] When the disc brush assembly is installed on the base, the positioning component prevents the disc brush assembly from shifting radially, allowing the drive head to automatically align with the mounting slot of the disc brush assembly as coaxially as possible. This initial coarse positioning enables fast and accurate assembly, while avoiding component wear or transmission failure caused by radial misalignment.
[0013] In some embodiments, the connector includes a resilient snap-fit element. The drive head, driven by the lifting assembly, overcomes the elastic force of the snap-fit element and descends relative to the bracket until it extends into the mounting slot and is fixed relative to the snap-fit element. This cleaning chassis, through the lifting assembly driving the drive head to overcome the elastic force of the connector and descend into the mounting slot for fixation, achieves automatic installation and removal of the disc brush. The operation is convenient and the connection is stable, avoiding the alignment difficulties and loosening problems of traditional manual installation methods. Furthermore, this structure is simple, reliable, and highly efficient, significantly improving the user experience.
[0014] In some embodiments, the drive head includes a guide portion for extending into the mounting groove and a fixing post axially connected to the guide portion. The fixing post is located on the side of the guide portion facing away from the mounting groove. The elastic locking element is a retaining spring surrounding the periphery of the mounting groove. During the insertion of the drive head into the mounting groove, the retaining spring is sleeved on the guide portion and can be elastically opened under the compression of the guide portion, sliding along the axial direction of the guide portion towards the fixing post until the retaining spring automatically retracts and elastically engages with the outer circumferential surface of the fixing post after passing around the guide portion. When the drive head extends into the mounting groove, the retaining spring is elastically opened by the compression of the guide portion and slides along the axial direction of the guide portion to the position of the fixing post. Subsequently, after passing around the guide portion, it automatically retracts under its own elastic force and locks with the outer circumferential surface of the fixing post, achieving a stable connection. This structure guides the retaining spring to precise positioning through the guide portion and achieves self-locking through elastic deformation, ensuring that the disc brush is installed firmly and conveniently.
[0015] In some embodiments, multiple limiting ribs are formed on the outer peripheral surface of the guide portion. These ribs are evenly spaced along the circumference of the guide portion. One end of each limiting rib near the fixing post protrudes radially outward from the guide portion, forming a guide flange. The outer contour of the guide portion's cross-section at the guide flange is larger than the outer contour of the fixing post's cross-section. During the insertion of the guide portion into the mounting groove, the retaining spring is elastically expanded under the pressure of the guide flange until it automatically retracts and elastically engages with the outer peripheral surface of the fixing post after passing the guide flange. When the drive head enters the mounting groove, the retaining spring first contacts the guide flange and elastically expands under its pressure, then slides along the guide portion. After the retaining spring has completely passed the guide flange, it automatically retracts due to its own elastic restoring force, tightly locking onto the outer peripheral surface of the fixing post. This structure ensures accurate guidance and reliable expansion of the retaining spring through the guide flange, and also achieves self-locking fixation after connection, making the connection between the brush assembly and the drive head more stable and reliable.
[0016] In some embodiments, a guide ramp is formed on the side of the guide flange facing away from the fixing post. This guide ramp abuts against the retaining spring as the guide portion extends into the mounting groove to expand the retaining spring until it automatically retracts and elastically engages with the outer circumferential surface of the fixing post after passing over the guide flange. When the drive head enters the mounting groove, the retaining spring first contacts the guide ramp and gradually expands outward under its guidance. As the drive head continues to move downward, the retaining spring slides along the guide ramp until it completely passes over the guide flange, then automatically retracts due to its own elastic restoring force, tightly locking onto the outer circumferential surface of the fixing post. This guide ramp design significantly reduces the frictional resistance during retaining spring expansion, making the installation process smoother, while ensuring the retaining spring can smoothly transition to the locked position, thus improving assembly efficiency and ensuring structural stability after connection.
[0017] In some embodiments, multiple mating ribs are formed on the wall of the mounting groove. These ribs are evenly spaced along the circumference of the mounting groove, and the number of mating ribs is equal to the number of limiting ribs. When the guide portion is inserted into the mounting groove, any one of the limiting ribs inserts into the gap between any two adjacent mating ribs. When the drive head rotates, it can abut against the limiting ribs and mating ribs to drive the bracket and the disc brush connected to the bracket to rotate. When the guide portion is inserted into the mounting groove, the limiting ribs and mating ribs interlock, meaning each limiting rib inserts into the gap between two adjacent mating ribs, and each mating rib is embedded in the gap between two adjacent limiting ribs. This interlocking structure forms circumferential positioning, allowing the drive head to directly transmit torque to the bracket and disc brush through the side contact between the limiting ribs and mating ribs when rotating. This design not only achieves axial anti-detachment but also ensures efficient power transmission through the rib-groove fit, significantly improving assembly convenience and transmission reliability.
[0018] In some embodiments, the end of the limiting rib away from the fixing post has a first positioning slope, and the end of the mating rib away from the bottom of the mounting groove has a second positioning slope. During the insertion of the guide portion into the mounting groove, the first positioning slope of the limiting rib abuts against the second positioning slope of the mating rib to guide the guide portion into the mounting groove. When the guide portion is inserted into the mounting groove, the first and second positioning slopes contact and slide together, forming a progressive guiding effect. This effectively reduces the alignment accuracy requirements during assembly, allows components to self-correct insertion in a non-strictly coaxial state, significantly improves assembly efficiency, and ensures that the drive head and mounting groove are aligned. Simultaneously, it ensures that the limiting rib and mating rib ultimately form a precise torque transmission fit.
[0019] In some embodiments, each of the mating ribs forms a guide slope on both sides of the second positioning slope in the circumferential direction of the mounting groove. During the insertion of the guide portion into the mounting groove, each limiting rib can be inserted into the gap between any two adjacent mating ribs, guided by the guide slope. When the guide portion is inserted into the mounting groove, the limiting rib first achieves initial alignment by contacting the first and second positioning slopes; as the insertion depth increases, the limiting rib further contacts the guide slopes on both sides. Under the synergistic effect of the two guide slopes, the brush assembly adaptively rotates, allowing the limiting rib to be precisely guided into the gap between two adjacent mating ribs.
[0020] In some embodiments, the positioning component includes positioning blocks disposed on the base. Multiple positioning blocks are arranged around the periphery of each disc brush assembly to restrict its radial movement. The side of the positioning block facing the disc brush assembly is arc-shaped to fit the disc brush assembly. This arrangement, with evenly distributed positioning blocks forming a ring constraint, ensures stable alignment of the disc brush assembly. Furthermore, a clearance can be provided between the positioning blocks and the disc brush assembly to ensure smooth assembly and effectively suppress vibration displacement, thus ensuring structural strength while also facilitating maintenance.
[0021] In some embodiments, the positioning assembly includes positioning posts disposed on the base, with multiple positioning posts arranged around the periphery of each brush assembly to restrict radial movement of the brush assembly. This arrangement, with the circumferentially distributed positioning posts forming a rigid limiting structure, ensures radial positioning of the brush assembly. Simultaneously, a clearance can be reserved between the positioning posts and the brush assembly to ensure smooth assembly and effectively suppress vibration displacement, thus ensuring structural strength while also facilitating maintenance.
[0022] In some embodiments, the cleaning chassis further includes a positioning component and a baffle plate. The baffle plate is rotatably connected to the base. The positioning component includes a first limiting block disposed on the base and a second limiting block disposed on the baffle plate. The second limiting block can move to a positioning position and a non-positioning position under the action of the baffle plate. In the positioning position, the first limiting block and the second limiting block are spaced apart around the circumference of the brush assembly to limit the radial movement of the brush assembly. In the positioning position, the first limiting block and the second limiting block are spaced apart around the circumference of the brush assembly, forming a radial constraint on the brush assembly, and performing preliminary positioning of the brush assembly before the drive head is inserted into the mounting slot. In the non-positioning position, the second limiting block moves away from the first limiting block as the baffle plate rotates, expanding the installation space around the brush assembly and facilitating quick disassembly and maintenance.
[0023] In some embodiments, the resilient snap-fit element is configured to detach from the drive head under external force. This design achieves reversible snap-fit through elastic deformation, ensuring a reliable connection between the drive head and the disc brush assembly during normal operation, while allowing the snap-fit element to elastically deform and release during maintenance by applying external force (such as manual pressing or prying with a tool), facilitating quick disassembly of the disc brush assembly for replacement or cleaning. This structure significantly improves the maintainability of the equipment while ensuring transmission stability, and is particularly suitable for cleaning applications requiring periodic replacement of worn parts.
[0024] This application also provides a cleaning device, which includes a main body and a cleaning chassis connected to the main body as described in any of the above embodiments.
[0025] Since the cleaning equipment described above includes the cleaning chassis described in any of the above embodiments, the cleaning equipment also has at least the following beneficial effects: the cleaning chassis of the cleaning equipment overcomes the elastic force of the elastic snap-fit component by driving the lifting component to descend and extend into the mounting groove for fixation, thereby realizing the automatic installation and disassembly of the disc brush. The operation is convenient and the connection is stable, avoiding the alignment difficulties and loosening problems of the traditional manual installation method. At the same time, the structure is simple and reliable, with high installation efficiency, significantly improving the user experience. Attached Figure Description

[0044] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0045] Please see Figures 1 to 12 In some embodiments, this utility model provides a cleaning chassis 10, which includes a base 100, a lifting assembly 200, a driving assembly 300, and a disc brush assembly 400. The lifting assembly 200 is disposed on the base 100; the driving assembly 300 includes a driving member 310 disposed on the base 100 and a driving head 320 connected to the driving member 310, the driving head 320 being rotatable under the drive of the driving member 310. The disc brush assembly 400 includes a bracket 410, a disc brush 420 disposed below the bracket 410, and a connecting member 430 disposed on the bracket 410. The bracket 410 is provided with a mounting groove 411, such as... Figure 10 , Figure 11 and Figure 12 As shown, the drive head 320 can extend into the mounting groove 411 under the drive of the lifting assembly 200, and the drive head 320 is fixed relative to the connector 430.
[0046] The aforementioned cleaning chassis 10 offers at least the following advantages: The cleaning chassis 10, through the lifting assembly 200, lowers the drive head 320 and inserts it into the mounting slot 411 for fixation, achieving automatic installation and removal of the disc brush 420. This facilitates convenient operation and stable connection, avoiding the alignment difficulties and loosening issues of traditional manual installation methods. Furthermore, the structure is simple, reliable, and highly efficient, significantly improving the user experience. When the disc brush assembly 400 is installed on the base 100, the positioning assembly 500 prevents radial displacement of the disc brush assembly 400, ensuring that the drive head 320 automatically maintains coaxial alignment with the mounting slot 411 of the disc brush assembly as much as possible. This initial coarse positioning enables rapid and accurate assembly, while preventing component wear or transmission failure due to radial misalignment.
[0047] In some embodiments, the connector 430 includes an elastic snap-fit member 431. The drive head 320, driven by the lifting assembly 200, overcomes the elastic force of the snap-fit member 431 and descends relative to the bracket 410 until the drive head 320 extends into the mounting groove 411 and is fixed relative to the snap-fit member 431. The cleaning chassis 10, through the lifting assembly 200 driving the drive head 320 to overcome the elastic force of the connector 430 and extend into the mounting groove 411 for fixation, achieves automatic installation and removal of the disc brush 420. This is convenient to operate and provides a stable connection, avoiding the alignment difficulties and loosening problems of traditional manual installation methods. Furthermore, this structure is simple, reliable, and highly efficient, significantly improving the user experience. In other embodiments, the connector 430 includes a rotating snap-fit member. After being inserted into the mounting groove 411, the drive head 320 can rotate under the drive of the drive member 310 and engage with the rotating snap-fit member. In some other embodiments, the connector 430 includes a torsion spring, and the drive head 320, driven by the drive member 310, can overcome the elastic force of the torsion spring and insert into the mounting groove 411. After the drive head 320 is inserted into the mounting groove 411, the torsion spring can reset under its own elastic force to engage with the drive head 320.
[0048] like Figures 6 to 12 As shown, in some embodiments, the drive head 320 includes a guide portion 321 for extending into the mounting groove 411 and a fixing post 322 connected axially to the guide portion 321. The fixing post 322 is located on the side of the guide portion 321 facing away from the mounting groove 411. The elastic snap-fit member 431 is a snap ring surrounding the periphery of the mounting groove 411. During the process of the drive head 320 extending into the mounting groove 411, the snap ring is sleeved on the guide portion 321 and can be elastically opened under the compression of the guide portion 321, and slides along the axial direction of the guide portion 321 towards the fixing post 322 until the snap ring automatically retracts and elastically snaps onto the outer periphery of the fixing post 322 after passing around the guide portion 321. When the drive head 320 extends into the mounting slot 411, the retaining ring is elastically opened by the guide part 321 and slides axially along the guide part 321 to the position of the fixing post 322. Then, after passing around the guide part 321, it automatically retracts under its own elastic force and locks into the outer circumference of the fixing post 322, achieving a stable connection. This structure guides the retaining ring to precise positioning through the guide part 321 and uses elastic deformation to achieve self-locking, ensuring that the disc brush 420 is firmly installed and easy to install.
[0049] like Figure 5 , Figure 6 , Figure 10 , Figure 11 and Figure 12As shown, in some embodiments, the outer peripheral surface of the guide portion 321 is provided with a plurality of limiting ribs 3211. The limiting ribs 3211 are equally spaced along the circumference of the guide portion 321. One end of the limiting rib near the fixing post protrudes radially outward along the guide portion 321 to form a guide flange. The outer contour of the cross section of the guide portion 321 at the location of the guide flange is larger than the outer contour of the cross section of the fixing post 322. During the process of the guide portion 321 extending into the mounting groove 411, the retaining spring can be elastically opened under the compression of the guide flange until the retaining spring automatically retracts and elastically engages with the outer peripheral surface of the fixing post 322 after passing over the guide flange. When the drive head 320 extends into the mounting groove 411, the retaining spring first contacts the guide flange and elastically expands under its compression, and then slides along the guide portion 321; after the retaining spring has completely passed the guide flange, it automatically retracts by its own elastic restoring force and tightly engages with the outer peripheral surface of the fixing post 322. This structure ensures precise guidance and reliable expansion of the snap ring through the guide flange, and also achieves self-locking fixation after connection, making the connection between the brush assembly 400 and the drive head 320 more stable and reliable.
[0050] like Figure 6 and Figure 11 As shown, in some embodiments, a guide ramp 3213 is formed on the side of the guide flange facing away from the fixing post 322. The guide ramp 3213 is used to abut against the retaining spring as the guide portion 321 extends into the mounting groove 411 to open the retaining spring until the retaining spring automatically retracts and elastically engages with the outer circumferential surface of the fixing post 322 after passing around the guide flange. When the drive head 320 extends into the mounting groove 411, the retaining spring first contacts the guide ramp 3213 and gradually expands outward under the guidance of the ramp. As the drive head 320 continues to move downward, the retaining spring slides along the guide ramp 3213 until it completely passes over the guide flange, and then automatically retracts by its own elastic restoring force, tightly engaging with the outer circumferential surface of the fixing post 322. This guide ramp 3213 design significantly reduces the frictional resistance when the retaining spring expands, making the installation process smoother, while ensuring that the retaining spring can smoothly transition to the locked position, which improves assembly efficiency and ensures the structural stability after connection.
[0051] like Figure 9As shown, in some embodiments, a plurality of mating ribs 412 are formed on the wall of the mounting groove 411. The mating ribs 412 are equally spaced along the circumference of the mounting groove 411, and the number of mating ribs 412 is equal to the number of limiting ribs 3211. When the guide part 321 is inserted into the mounting groove 411, any one of the limiting ribs 3211 is inserted into the gap between any two adjacent mating ribs 412, and any one of the mating ribs 412 is inserted into the gap between any two adjacent limiting ribs 3211. When the drive head 320 rotates, it can abut against the mating ribs 412 through the limiting ribs 3211 to drive the bracket 410 and the disc brush 420 connected to the bracket 410 to rotate. When the guide part 321 is inserted into the mounting groove 411, the limiting ribs 3211 and the mating ribs 412 are staggered and interlocked, that is, each limiting rib 3211 is inserted into the gap between two adjacent mating ribs 412, and each mating rib 412 is embedded in the gap between two adjacent limiting ribs 3211. This interlocking structure creates circumferential positioning, allowing the drive head 320 to directly transmit torque to the bracket 410 and the disc brush 420 when rotating, through the side contact between the limiting rib 3211 and the mating rib 412. This design not only achieves axial anti-detachment but also ensures efficient power transmission through the rib groove fit, significantly improving the ease of assembly and transmission reliability.
[0052] like Figure 5 and Figure 9 As shown, in some embodiments, the end of the limiting rib 3211 away from the fixing post 322 forms a first positioning slope 3214, and the end of the mating rib 412 away from the bottom of the mounting groove 411 forms a second positioning slope 4121. During the process of the guide portion 321 extending into the mounting groove 411, the first positioning slope 3214 of the limiting rib 3211 abuts against the second positioning slope 4121 of the mating rib 412 to guide the guide portion 321 into the mounting groove 411. When the guide portion 321 is inserted into the mounting groove 411, the first positioning slope 3214 and the second positioning slope 4121 contact each other and slide to form a progressive guiding effect, effectively reducing the alignment accuracy requirements during assembly, allowing components to achieve self-correcting insertion in a non-strictly coaxial state, significantly improving assembly efficiency, enabling the drive head 320 and the mounting groove 411 to be aligned, and ensuring that the limiting rib 3211 and the mating rib 412 ultimately form a precise torque transmission fit.
[0053] like Figure 9As shown, in some embodiments, in the circumferential direction of the mounting groove 411, each of the mating ribs 412 forms a guide slope 4122 on both sides of the second positioning slope 4121. During the process of the guide portion 321 extending into the mounting groove 411, each limiting rib 3211 can be inserted into the gap between any two adjacent mating ribs 412 under the guidance of the guide slope 4122. When the guide portion 321 is inserted into the mounting groove 411, the limiting rib 3211 first contacts the second positioning slope 4121 through the first positioning slope 3214 to achieve initial alignment. As the insertion depth increases, the limiting rib 3211 further contacts the guide slopes 4122 on both sides. Under the synergistic effect of the two guide slopes 4122, the brush assembly 400 rotates adaptively, allowing the limiting rib 3211 to be precisely guided into the gap between two adjacent mating ribs 412.
[0054] like Figure 3 , Figure 13 , Figure 14 and Figure 15 As shown, in some embodiments, the cleaning chassis 10 further includes a positioning component 500 disposed on the base 100. The positioning component 500 can restrict the radial movement of the disc brush assembly 400 so that the drive head 320 can be aligned with the mounting slot 411. When the disc brush assembly 400 is installed on the base 100, the positioning component 500 can prevent the disc brush assembly 400 from shifting radially, so that the drive head 320 can automatically maintain coaxial alignment with the mounting slot 411 of the disc brush assembly as much as possible, i.e., perform preliminary coarse positioning. Thus, under the coordinated action of the inclined guide mechanism of the guide portion 321, fast and accurate assembly is achieved, while avoiding component wear or transmission failure caused by radial misalignment.
[0055] like Figure 13 and Figure 14As shown, in some embodiments, the positioning component 500 includes positioning blocks 530 disposed on the base 100. Multiple positioning blocks 530 are arranged around the periphery of each of the disc brush components 400 to restrict the radial movement of the disc brush component 400. The side of the positioning block 530 facing the disc brush component 400 is arc-shaped to fit the disc brush component 400. This arrangement, with the evenly distributed positioning blocks 530 forming a ring constraint, ensures that the disc brush component 400 remains stably centered. Simultaneously, a clearance can be reserved between the positioning blocks 530 and the disc brush component 400 to ensure smooth assembly and effectively suppress vibration displacement, thus ensuring structural strength while also facilitating maintenance.
[0056] like Figure 15 As shown, in some embodiments, the positioning component 500 includes positioning posts 540 disposed on the base 100, and a plurality of positioning posts 540 are arranged around the periphery of each of the disc brush components 400 to limit the radial movement of the disc brush component 400. This arrangement forms a rigid limiting structure through the circumferentially distributed positioning posts 540, ensuring radial positioning of the disc brush component 400. At the same time, a clearance can be reserved between the positioning posts 540 and the disc brush component 400 to ensure smooth assembly and effectively suppress vibration displacement, thus ensuring structural strength while taking into account maintenance convenience.
[0057] like Figure 3 As shown, in some embodiments, the cleaning chassis 10 further includes a positioning component 500 and a baffle plate 600. The baffle plate 600 is rotatably connected to the base 100. The positioning component 500 includes a first limiting block 510 disposed on the base 100 and a second limiting block 520 disposed on the baffle plate 600. The second limiting block 520 can move to a positioning position and a non-positioning position under the action of the baffle plate 600. In the positioning position, the first limiting block 510 and the second limiting block 520 are spaced apart around the circumference of the brush assembly 400 to limit the radial movement of the brush assembly 400. In the positioning position, the first limiting block 510 and the second limiting block 520 are spaced apart around the circumference of the brush assembly 400, forming a radial constraint on the brush assembly 400, and initially positioning the brush assembly 400 before the drive head 320 is inserted into the mounting slot 411. In the non-positioning position, the second limiting block 520 moves away from the first limiting block 510 as the baffle plate 600 rotates, expanding the installation space around the disc brush assembly 400 and facilitating quick disassembly and maintenance.
[0058] In some embodiments, the elastic snap-fit member 431 is configured to separate from the drive head 320 under external force. This design achieves reversible snap-fit through elastic deformation, ensuring a reliable connection between the drive head 320 and the disc brush assembly 400 under normal operating conditions, while allowing the snap-fit member to elastically deform and unlock during maintenance by applying external force (such as manual pressing or prying with a tool), facilitating quick disassembly of the disc brush assembly 400 for replacement or cleaning. This structure significantly improves the maintainability of the equipment while ensuring transmission stability, and is particularly suitable for cleaning applications requiring periodic replacement of worn parts.
[0059] like Figure 3 , Figure 13 , Figure 14 and Figure 15 As shown, in some embodiments, the number of the disc brush assemblies 400 can be set to multiple, and the drive assembly 300 corresponds one-to-one with the disc brush assembly 400. Accordingly, the positioning assembly 500 is also adapted accordingly.
[0060] In some embodiments, the elastic snap-fit member 431 can be connected to the bracket 410 by a detachable connection method such as a threaded connection or a snap-fit, for example... Figure 8 As shown, the retaining ring is threadedly connected to the bracket 410 via fastener 440.
[0061] In addition, this application also provides a cleaning device, which includes a main body and a cleaning chassis 10 as described in any of the above embodiments connected to the main body.
[0062] Since the cleaning equipment described above includes the cleaning chassis 10 as described in any of the above embodiments, the cleaning equipment also has at least the following beneficial effects: the cleaning chassis 10 of the cleaning equipment overcomes the elastic force of the elastic snap-fit 431 by driving the head 320 of the lifting component 200 to descend and extend into the mounting groove 411 for fixation, thereby realizing the automatic installation and disassembly of the disc brush 420. The operation is convenient and the connection is stable, avoiding the alignment difficulties and loosening problems of the traditional manual installation method. At the same time, the structure is simple and reliable, with high installation efficiency, significantly improving the user experience.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0066] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0067] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0068] In this utility model, unless otherwise explicitly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact, or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0069] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this invention are for illustrative purposes only and do not represent the only possible implementation.
[0070] In this specification, the use of terms such as "an embodiment," "another implementation," etc., refers to a specific feature, structure, material, or characteristic described in connection with that embodiment or example that is included in at least one embodiment or example of the present invention. In this specification, the illustrative descriptions of the above terms do not necessarily refer to the same embodiment or example. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
