[0041] Example 1

[0042] like Figure 1 and Figure 3 As shown, the dust cup structure 20 proposed in this embodiment may include a dust cup barrel 100, a separator 300 provided in the dust cup barrel 100, and a dust cup cleaning structure provided on the dust cup barrel 100, and a filter outer cavity 104 is formed between the dust cup barrel 100 and the separator 300. Fine particles, floating dust, hair and other dirt can be collected through the filter outer cavity 104 between the dust cup barrel 100 and the separator 300, and the fine particles, floating dust, hair and other dirt in the filter outer cavity 104 can be cleaned through the dust cup cleaning structure provided on the dust cup barrel 100 and extending into the filter outer cavity 104.

[0043] Specifically, the dust cup barrel 100 has a mounting cavity 102, the separator 300 is disposed in the mounting cavity 102, and the above-mentioned filtering outer cavity 104 is formed between the outer wall surface of the separator 300 and the inner wall surface of the mounting cavity 102. In addition, the dust cup cleaning structure may include at least one cutting member 500 provided on the dust cup barrel 100, the cutting member 500 is located in the filtering outer cavity 104, and the cutting end of the cutting member 500 faces and is close to the outer wall surface of the separator 300.

[0044] One or more cutting pieces 500 provided on the dust cup barrel 100 can be moved relative to the separator 300, so that the cutting end face of the cutting piece 500 close to the outer wall of the separator 300 can cut the hair wrapped around the outer wall of the separator 300, so that the hair falls off the outer wall of the separator 300. At the same time, the cutting piece 500 can be used to scrape and clean the outer wall of the separator 300, so that the stains, dust and hair on the outer wall of the separator 300 can be cleaned, so that the dust cup structure 20 can be cleaned simply and conveniently, thereby preventing the separator 300 from being blocked, ensuring the working performance of the dust cup structure 20, and improving the user experience.

[0045] Moreover, the dust cup cleaning structure may include a mounting base provided on the dust cup cylinder 100, and the cutting member 500 is provided on the mounting base. That is, the cutting member 500 may be provided not only directly on the dust cup cylinder 100, but also by providing a mounting base on the dust cup cylinder 100 for installing the cutting member 500.

[0046] Furthermore, the mounting base of the dust cup cleaning structure can be provided on the inner wall surface of the dust cup cylinder 100. Specifically, the mounting base can be integrally formed with the dust cup cylinder 100, that is, the dust cup cylinder 100 can serve as the mounting base of the dust cup cleaning structure, and the cutting member 500 can be provided on the inner wall surface of the dust cup cylinder 100. Alternatively, a protruding structure can be provided on the inner wall surface of the dust cup cylinder 100 to form the mounting base, and the cutting member 500 can be provided on the protruding structure. In addition, the mounting base can also be detachably connected to the dust cup cylinder 100, for example, a locking groove or a locking protrusion can be provided on the inner wall surface of the dust cup cylinder 100 to lock the mounting base to the inner wall surface of the dust cup cylinder 100.

[0047] Moreover, when the mounting seat of the dust cup cleaning structure is provided on the inner wall surface of the dust cup cylinder 100, the separator 300 can be separated from the dust cup cylinder 100. In this way, when the separator 300 is separated from the dust cup cylinder 100 and moved relative to each other in the axial direction, the cutting member 500 provided on the inner wall surface of the dust cup cylinder 100 can cut the hair and other debris entangled on the outer wall surface of the separator 300, thereby cutting off the hair and other debris, thereby facilitating the cleaning of the hair and other debris from the separator 300 and cleaning them outside the dust cup structure 20.

[0048] In addition, the mounting base may include a dust cup cover 200 covering the open end of the dust cup cartridge 100, and a connector 400 connected to the dust cup cover 200, a cutting member 500 provided on the connector 400, and the connector 400 and the cutting member 500 may extend into the filter outer cavity 104 of the dust cup cartridge 100. That is, the top end of the dust cup cartridge 100 may be set as the open end, and the dust cup cover 200 may be provided at the open end, so that the mounting base is indirectly provided on the dust cup cartridge 100 through the dust cup cover 200 connected to the dust cup cartridge 100. During the use of the dust cup structure, the dust cup cover 200 is covered on the open end of the dust cup tube 100, and the separator 300 can be sealed in the installation cavity 102 (at this time, the separator 300 can be installed in the installation cavity 102 of the dust cup tube 100), so that dust, hair and other dirt can be collected and stored in the filter outer cavity 104; and when the dust cup structure needs to be cleaned, the dust cup cover 200 can be opened to open the open end of the dust cup tube 100, so that dust, hair and other dirt can be cleaned out of the dust cup tube 100.

[0049] Moreover, since the cutting piece 500 is connected to the dust cup cover 200 through the connecting piece 400, when the dust cup cover 200 is opened, the cutting piece 500 corresponding to the outer wall surface of the separator 300 can cut the hair and other debris entangled on the outer wall surface of the separator 300, and these hair and other debris can be cut off and fall off from the outer wall surface of the separator 300 into the filter outer cavity 104, making it convenient to clean these dirt out from the opening of the dust cup tube 100.

[0050] In addition, the separator 300 may include a separation barrel 310 provided on the bottom wall of the mounting cavity 102 of the dust cup cartridge 100, a cylindrical filter screen 320 provided on the separation barrel 310, and a cylindrical separation cover 330 provided on the filter screen 320. By sequentially connecting the separation barrel 310, the filter screen 320, and the separation cover 330, a separator 300 is formed to be installed in the mounting cavity 102 of the dust cup cartridge 100. When fine particles, dust, hair, and other dirt are sucked into the dust cup cartridge 100, they are separated by the separator 300, so that gas and even finer particles and dust pass through the filter screen 320 and enter the filter inner cavity of the separator 300, while larger particles, dust, hair, and other dirt are isolated and collected in the filter outer cavity 104 between the dust cup cartridge 100 and the separator 300. In addition, the above-mentioned separation barrel 310, filter screen 320 and separation cover 330 can all be set as cylindrical structures; according to needs, the above-mentioned separation barrel 310, filter screen 320 and separation cover 330 can also be set as structures of other shapes (such as rectangular, semicircular, conical, etc.).

[0051] Furthermore, a HEPA filter (not shown) can be installed in the filter cavity of separator 300 to further filter the air entering the filter cavity. Furthermore, the HEPA filter can also be configured as a hollow cylindrical structure to filter the air in filter screen 320 from the outer periphery. Furthermore, the filter cavity of separator 300 can be connected to an external vacuum suction device to suck the air in the filter cavity out of the cleaning device.

[0052] In addition, if Figure 4As shown, the cutting member 500 may include a tool holder 510 connected to the mounting seat, and a cutting blade body 520 provided on the tool holder 510. The blade surface of the cutting blade body 520 is set as the above-mentioned cutting end surface and faces the outer wall surface of the separator 300. By arranging the tool holder 510 on the mounting seat, the cutting blade body 520 can be stably and reliably arranged on the tool holder 510. Moreover, by arranging the tool holder 510 and the cutting blade body 520, the outer wall surface of the separator 300 and the inner wall surface of the mounting cavity 102 can be scraped, and dirt, dust, and other impurities on the outer wall surface of the separator 300 and the inner wall surface of the mounting cavity 102 can be scraped off, making it convenient to clean the dust cup structure 20. In addition, not only can the tool holder 510 be set separately for setting the cutting blade body 520, but the above-mentioned cutting blade body 520 can also be directly set on the mounting seat (that is, the mounting seat is set as the tool holder 510).

[0053] Furthermore, the blade of the cutting blade 520 can be directly opposite or obliquely opposite the outer wall of the separator 300, that is, directly opposite or obliquely opposite the outer wall of the filter 320 of the separator 300. Because hair and other slender objects can easily become entangled in the mesh of the filter 320, the blade of the cutting blade 520 is aligned with the outer wall of the filter 320, making it easier to cut hair entangled on the outer wall of the filter 320, freeing the hair from the filter 320 for easy removal. Furthermore, the cutting blade 520 can be positioned not only along the axial direction of the separator 300, but also along the circumference of the separator 300, or simultaneously along the axial and circumferential directions of the separator 300. That is, the intersection surface of the blade of the cutting body 520 and the outer wall surface of the cylindrical filter net 320 can be the axial normal surface of the cylindrical separator 300, or an inclined surface intersecting the axial normal surface of the cylindrical separator 300; in addition, the intersection surface of the blade of the cutting body 520 and the outer wall surface of the cylindrical filter net 320 can also be the cross-section of the cylindrical separator 300.

[0054] Furthermore, the cutting blade 520 can be bent from the inner wall of the mounting cavity 102 of the dust cup barrel 100 toward the outer wall of the separator 300 and positioned close to it. That is, the blade of the cutting blade 520 can be set in an arc shape, so that the blade of the cutting blade 520 gradually bends and approaches the outer wall of the separator 300, and the cutting gap between the blade of the cutting blade 520 and the outer wall of the separator 300 can be gradually reduced. This not only facilitates the placement of the cutting blade 520 and the cutting element 500 on the outer periphery of the separator 300, but also facilitates the gradual cutting of hair and other debris on the outer wall of the filter 320 of the separator 300 (allowing hair and other debris to gradually enter the cutting gap for cutting). In addition, the distance between the blade of the cutting blade 520 and the outer wall of the separator 300 can be kept constant, resulting in a simple structure.

[0055] Moreover, the cutting blade 520 can be extended along the axial direction of the separator 300. Specifically, Figure 4 As shown, the cutting blade body 520 may include a blade root portion 522 connected to the blade holder 510, and a blade tip portion 524 protruding from the blade root portion 522. Furthermore, the blade root portion 522 may be bent from the blade holder 510 toward the outer wall of the separator 300, and the blade tip portion 524 may be extended from the end of the blade root portion 522 along the axial direction of the outer wall of the separator 300. The blade tip portion 524 extending axially along the outer wall of the separator 300 can cut objects such as hair entangled in the circumferential direction of the outer wall of the separator 300.

[0056] Moreover, the end of the blade tip 524 can be arranged to extend along the axial direction of the outer wall surface of the separator 300, and at the same time bend and extend in a direction away from the outer wall surface of the separator 300. That is, when the blade tip 524 extends along the axial direction of the outer wall surface of the separator 300, it can also gradually deviate in a direction away from the outer wall surface of the separator 300, so that a V-shaped cutting gap is formed between the blade tip 524 and the outer wall surface of the separator 300. In this way, when the cutting blade body 520 moves along the axial direction of the separator 300 toward the top of the dust cup cylinder 100 and uses the blade tip 524 to cut the hair wrapped around the outer wall surface of the separator 300, the hair can gradually enter the cutting gap of the blade tip 524 and be gradually cut, which is not easy to damage the blade. Similarly, a similar V-shaped cutting gap can be formed between the blade root 522 and the outer wall of the separator 300. When the cutting blade body 520 moves along the separator 300 toward the bottom end (the end away from the top) of the dust cup barrel 100 and uses the blade root 522 to cut the hair wrapped around the outer wall of the separator 300, the hair can gradually enter the cutting gap of the blade root 522 and be gradually cut. In this way, by moving the cutting blade body 520 back and forth along the axial direction of the separator 300, the hair wrapped around the outer wall of the separator 300 can be repeatedly cut and cleaned from the axial direction, cleaning more thoroughly. Moreover, the cutting blade body 520 can be rotated along the circumference of the separator 300 to repeatedly cut and clean the hair wrapped around the outer wall of the separator 300 from the circumference.

[0057] In addition, a guide groove (not shown in the figure) may be provided on the outer wall surface of the separator 300 along the axial direction, and the blade of the cutting blade body 520 extending along the axial direction may be provided corresponding to the guide groove extending along the axial direction. By providing the guide groove along the axial direction on the outer wall surface of the separator 300, the cutting blade body 520 can move along the guide groove during the process of reciprocating along the axial direction of the separator 300, which is stable and reliable. Moreover, the above-mentioned guide groove may be provided only on the filter screen 320 of the separator 300, or may be provided simultaneously on the separation barrel 310, the filter screen 320 and the separation cover 330 of the separator 300. Moreover, as needed, a plurality of cutting blade bodies 520 may be provided, and a plurality of guide grooves may be provided correspondingly, so that one cutting blade body 520 corresponds to at least one guide groove.

[0058] In addition, a cup tube guide groove can be set along the axial direction on the inner wall surface of the dust cup tube 100, and a tool guide protrusion can be set on the tool seat 510, so that the tool guide protrusion can be slidably clamped in the cup tube guide groove, and the cutting blade 520 can also be stably moved along the axial direction of the separator 300; in addition, a cup tube guide protrusion can be set along the axial direction on the inner wall surface of the dust cup tube 100, and a tool guide groove can be set on the tool seat 510, so that the cup tube guide protrusion can be slidably clamped in the tool guide groove, and the cutting blade 520 can also be stably moved along the axial direction of the separator 300.

[0059] Furthermore, the cutting element 500 may include a single cutter seat 510 and a single cutting blade 520 disposed on the cutter seat 510, or may include a single cutter seat 510 and at least two cutting blades 520 disposed on the cutter seat 510. Furthermore, the cutting element 500 may include multiple cutter seats 510 and multiple cutting blades 520, with the multiple cutting blades 520 disposed one-to-one on the multiple cutter seats 510, or multiple cutting blades 520 disposed on each cutter seat 510. Furthermore, all the cutting blades 520 may be arranged in a circle around the outer periphery of the separator 300, or may be arranged in multiple circles around the outer periphery of the separator 300.

[0060] Furthermore, the cutter holder can be configured as an annular plate 510 located in the filter outer cavity 104 between the dust cup cylinder 100 and the separator 300. The annular plate 510 can be arranged around the outer periphery of the separator 300, and the cutting blade 520 can be arranged on the annular plate 510. The annular plate 510 can be arranged on a mounting seat (which can be directly or indirectly connected to the dust cup cylinder 100 via the mounting seat). By configuring the cutter holder 510 as an annular plate (which can be a circular ring plate or a circular segment plate), it is not only convenient to set the cutting blade 520, but also convenient to connect to the mounting seat so that it can be moved through the dust cup cover 200, and it can also scrape and clean the inner wall surface of the dust cup cylinder 100 and the outer wall surface of the separator 300. In addition, the cutter holder 510 can also be configured as an arc-shaped plate located on the outer periphery of the separator 300, or a rectangular plate, or other non-annular plate structure.

[0061] Furthermore, in this embodiment, when the cutter holder 510 is configured as an annular plate, the cutting member 500 may include a plurality of cutting blades 520 disposed on the annular plate 510. The plurality of cutting blades 520 may be evenly disposed around the outer periphery of the separator 300. That is, by disposing the plurality of cutting blades 520 on the cutter holder formed by a single annular plate 510, hair entangled on the outer periphery of the separator 300 may be cut simultaneously from multiple positions.

[0062] In addition, a cutting blade 520 may be provided on the annular plate 510 to cut the hair wrapped around the outer peripheral side of the separator 300 from one position; in addition, a plurality of annular plates 510 may be provided simultaneously and sequentially along the axial direction of the separator 300, and one or more cutting blades 520 may be provided on each annular plate 510 to cut the hair wrapped around the outer peripheral side of the separator 300 from multiple positions.

[0063] In addition, a base snap ring 312 may protrude from the outer circumference of the separation barrel 310 of the separator 300. The base snap ring 312 may mate with a cutter holder 510, which is configured as an annular plate. Specifically, when the dust cup cover 200 is placed on the dust cup cartridge 100, the cutting element 500 is in its initial position within the filter outer cavity 102. At this time, the cutter holder 510 (i.e., the annular plate) of the cutting element 500 surrounds the base snap ring 312, allowing the annular plate 510 to contact the base snap ring 312. This creates a seal at the base snap ring 312 of the separation barrel 310, preventing dirt, dust, hair, and other contaminants from falling onto the bottom wall of the dust cup cartridge 100, making cleaning inconvenient. Furthermore, the base snap ring 312 can also limit the cutter holder 510 and the cutting element 500, preventing them from excessively moving to the bottom of the dust cup cartridge 100 and causing damage.

[0064] In addition, the outer side of the annular plate 510 can correspond to the inner wall surface of the installation cavity 102 of the dust cup cylinder 100, and the inner side of the annular plate 510 can correspond to the outer wall surface of the separator 300. Moreover, the outer edge of the annular plate 510 can be made to correspond to the inner wall surface of the installation cavity 102, that is, the inner wall surface of the installation cavity 102 can be scraped and cleaned by the outer edge of the annular plate 510, and dirt, dust, hair and other impurities on the inner wall surface of the installation cavity 102 can be cleaned; the inner edge of the annular plate 510 can be made to correspond to the outer wall surface of the separator 300, that is, the inner edge of the annular plate 510 can be made to correspond to the outer wall surface of the separator 300, that is, the outer wall surface of the separator 300 can be scraped and cleaned by the inner edge of the annular plate 510, and dirt, dust, hair and other impurities on the outer wall surface of the separator 300 can be cleaned. In addition, a gap may be provided between the outer edge of the annular plate 510 and the inner wall of the installation cavity 102 , and a gap may be provided between the inner edge of the annular plate 510 and the outer wall of the separator 300 .

[0065] In addition, the dust cup cleaning structure may include a flexible cleaning outer ring (not shown in the figure) or / and a flexible cleaning inner ring (not shown in the figure) provided in the filter outer cavity 102 and connected to the mounting seat (which may be directly or indirectly connected to the dust cup cylinder 100 through the mounting seat). The flexible cleaning outer ring may abut against the inner wall surface of the mounting cavity 102, and the flexible cleaning inner ring may abut against the outer wall surface of the separator 300. The flexible cleaning outer ring connected to the mounting seat can scrape and clean the inner wall surface of the mounting cavity 102, and the flexible cleaning inner ring connected to the mounting seat can scrape and clean the outer wall surface of the separator 300. Moreover, the above-mentioned flexible cleaning outer ring (or flexible cleaning inner ring) may be directly provided on the mounting seat, or directly provided on the tool holder 510 (that is, indirectly connected to the mounting seat).

[0066] Moreover, the flexible cleaning outer ring can be detachably mounted on the outside of the tool holder 510, and the flexible cleaning inner ring can be detachably mounted on the inside of the tool holder 510. That is, the flexible cleaning outer ring and the flexible cleaning inner ring can be detachably mounted on the outside and inside of the tool holder 510, respectively, and arranged on the tool holder 510 simultaneously with the cutting blade 520, resulting in a more compact and simple structure. Furthermore, when the tool holder 510 is configured as an annular plate, the flexible cleaning outer ring can be arranged on the outside of the annular plate 510, and the flexible cleaning ring can be arranged on the inside of the annular plate 510. Furthermore, the flexible cleaning inner ring and the flexible cleaning outer ring can be arranged on the same annular plate 510, or on different annular plates 510. Furthermore, by detachably mounting the flexible cleaning outer ring and the flexible cleaning inner ring on the tool holder 510, they can be replaced and cleaned.

[0067] Moreover, the flexible cleaning inner ring and the flexible cleaning outer ring may each include at least one of an annular cleaning brush and an annular cleaning silica gel. That is, the flexible cleaning inner ring or the flexible cleaning outer ring may be configured as an annular cleaning brush detachably mounted on the tool holder 510 or the mounting base, or as an annular cleaning silica gel detachably mounted on the tool holder 510 or the mounting base, or as other annular flexible cleaning structures detachably mounted on the tool holder 510 or the mounting base (such as an annular cleaning rubber, an annular cleaning sponge, etc.). Furthermore, the flexible cleaning inner ring or the flexible cleaning outer ring may also be configured as a multi-layer cleaning structure, each including an annular cleaning brush and annular cleaning silica gel detachably connected to the tool holder 510 or the mounting base, wherein the annular cleaning brush and the annular cleaning silica gel are arranged side by side in two layers.

[0068] In addition, the above-mentioned connecting member 400 may include at least one connecting rod 410 (or connecting plate) connecting the tool holder 510 of the cutting member 500 and the dust cup cover 200. The tool holder 510 and the dust cup cover 200 can be connected by the connecting rod 410, which is simple and convenient. Moreover, one connecting rod 410 can be set to connect one or more tool holders 510, or multiple connecting rods 410 can be set at the same time to connect the dust cup cover 200 and one or more tool holders 510. In this embodiment, when the tool holder 510 is set as an annular plate, multiple connecting rods 410 can be evenly set to connect the annular plate 510 and the dust cup cover 200 from all sides. In addition, the tool holder 510 and the dust cup cover 200 can also be connected by other structures, such as connecting the tool holder 510 and the dust cup cover 200 by elastic connectors (springs) and other structures.

[0069] In addition, the dust cup cover 200 may include an outer cover 210, an inner cover 220 protruding from one end of the outer cover 210, and an elastic sealing ring (not shown) sleeved on the outer circumference of the inner cover 220. The connecting rod 410 of the connector 400 may be provided on the end surface of the inner cover 220. The inner cover 220 is clamped in the mounting cavity 102. The outer cover 220 is located outside the open end of the dust cup barrel 100, and the elastic sealing ring is tightly pressed against the end surface of the open end of the dust cup barrel 100. This can make the outer diameter of the inner cover 220 of the dust cup cover 200 smaller than the outer diameter of the outer cover 210, so that the dust cup cover 200 forms a stepped columnar structure, and the elastic sealing ring is located at the stepped surface.

[0070] In this way, it is easy to clamp the inner cover 220 into the open end of the dust cup canister 100, and the outer cover 210 is located outside the open end of the dust cup canister 100, and the elastic sealing ring is elastically sealed at the open end of the dust cup canister 100. By pressing the outer cover 210 of the dust cup cover 200 with force, the elastic sealing ring can pop up the dust cup cover 200, so that the open end of the dust cup canister 100 is separated from the inner cover 220, making it easier to move the dust cup cover 200, the mounting seat and the cutting member 500 along the axial direction of the separator 300. In addition, a snap switch can also be provided on the outer cover 210 or the inner cover 220, which can be snap-connected to the open end of the dust cup canister 100. By pressing the snap switch, the outer cover 210 or the inner cover 220 can be snap-locked or unlocked with the open end of the dust cup canister 100.

[0071] In addition, if Figure 5 and Figure 6 As shown, when the cutting member 500 is connected to the dust cup cover 200 through the connecting member 400, the working process of the dust cup structure 20 is as follows:

[0072] When it is necessary to clean the dust, hair and other dirt in the dust cup structure 20, the dust cup cover 200 can be pressed to make the dust cup cover 200 bounce about 1 mm relative to the dust cup tube 100 under the action of the elastic sealing ring. Then the user can pull the dust cup cover 200 out of the dust cup tube 100 at the trash can, and the tool holder 510 in the form of an annular plate connected to the dust cup cover 200 by a connecting piece (i.e., a plurality of connecting rods 410) (which may also include a flexible cleaning inner sleeve provided on the tool holder 510) is opened. The flexible cleaning ring and the flexible cleaning outer ring) will scrape off the dust, hair and other dirt in the dust cup tube 100 together with the pulling force. At the same time, the cutting blade 520 provided on the tool holder 510 (i.e., the annular plate) will cut off the hair wrapped around the filter 320 of the separator 300, and finally it will be brought out by the flexible cleaning inner ring that cleans the inner wall of the dust cup tube 100 and the flexible cleaning outer ring that cleans the outer wall of the separator until the cutting blade 520 is close to the open end of the dust cup tube 100.

[0073] After dust, stains, cut hair and other dirt are poured out of the dust cup tube 100, the dust cup cover 200 and the cutting piece 500 can be directly pushed back into the dust cup tube 100 to complete a self-cleaning of the dust cup structure 20.

The device body 10 can clean the floor and remove dirt such as dust, small particles, stains and hair on the cleaning surface, while the dust cup structure 20 can separate and collect these dirt to keep the cleaning surface clean.

[0076] Moreover, the dust cup structure 20 can be separately provided on the device body 10 and can be detachably connected to the device body 10. For example, the dust cup structure 20 can be detachably provided on the outside of the device body 10, and the dust cup structure 20 can be completely removed from the device body 10 for cleaning. Alternatively, a portion of the dust cup structure 20 (such as the dust cup cylinder 100) can be provided on the device body 10. Moreover, the dust cup structure 20 can be provided on the device body 10 horizontally or vertically.

[0077] In addition, the dust cup structure 20 can be integrated with the device body 10. For example, the dust cup tube 100 of the dust cup structure 20 can be integrated with the lower part of the device body 10, and the dust cup cover 200 of the dust cup structure 20 can be integrated with the upper part of the device body 10.

[0078] The cleaning device provided in this embodiment can use the opening process to simply clean the inner wall of the dust cup tube and the outer wall of the separator and deal with entangled hair each time the dust cup cover of the dust cup structure is opened, so that the dust cup structure remains clean and the problem of entangled hair being difficult to clean is solved.

[0079] Moreover, the cleaning device can be configured as a common vacuum cleaner (such as a handheld vacuum cleaner), or can be configured as a vacuum cleaner with a cleaning function, or can be configured as a floor cleaning machine with a dust collection function.

[0080] Obviously, the embodiments described above are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, those skilled in the art may make other different forms of changes or modifications without making any creative work, and all of these should fall within the scope of protection of the present invention.
