[0007] As living standards improve, people have higher and higher requirements for their home environment. Vacuum cleaning equipment has become increasingly popular due to its simple operation and ease of use. Vacuum cleaning equipment relies on a fan to generate negative pressure in the vacuuming channel, sucking in dust, dirt, and air from the suction part; the filtration system collects the dust and dirt, while the air is discharged by the fan.

[0008] In related technologies, with the use of vacuum cleaners, a lot of dust and dirt accumulate on the filters of the separation structure. If they are not cleaned for a long time, the filter screen will easily become clogged, the suction power will be reduced, and the dirt on the filter will be difficult to clean. It is necessary to disassemble the dust cup cover and remove the filter. If disassembly is frequent, it will easily reduce the sealing of the parts, affecting the service life and dust removal effect of the vacuum cleaner. Utility Model Content

[0094] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0095] Combination Figures 1 to 5The cleaning device 1000 according to an embodiment of this application includes: a body, a dust cup 11, and a dust scraping assembly. The body includes a first filter 12, and the dust cup 11 includes a cup body 111 and a cup lid 112, with the cup body 111 connected to the body. Specifically, the first filter 12 can separate dust from the gas containing dust within the cleaning device 1000. The dust cup 11 covers the outside of the first filter 12 and is used to collect the dust collected by the first filter 12. The end of the cup body 111 has a dust outlet, which is sealed by the cup lid 112 but can be opened, allowing dust inside the cup body 111 to be discharged through the dust outlet, thus cleaning the dust inside the cup body 111. More specifically, at least a portion of the dust scraping assembly is sleeved on the outside of the first filter 12 and adapted to reciprocate along the axial direction of the filter to scrape dust off the first filter 12. The dust scraping assembly is configured to drive the cup lid 112 to open, thereby scraping off the dust on the outside of the first filter 12, preventing the first filter 12 from becoming clogged, achieving a cleaning effect, and improving the performance of the first filter 12. It also facilitates dust collection. In addition, the dust scraping assembly can also be used to drive the cup lid 112 to open, so that the user does not need to open the lid manually, which can avoid dust generation and secondary pollution, and provide convenience for the user.

[0096] According to the embodiments of this application, the cleaning device 1000, by providing a scraper assembly, facilitates cleaning of the filter, improves the cleaning effect of the first filter 12, and also facilitates opening the cup lid 112, providing convenience for the user.

[0097] In practical applications, during the cleaning process of the cleaning device 1000, dust and dirt continuously accumulate on the first filter 12. If not cleaned regularly, this can easily clog the filter, reducing its filtration efficiency or suction power. Therefore, during use, the dust scraping component can be controlled to move, allowing it to move outside the first filter 12 and scrape off the dust and dirt from its outer surface. The scraped dust and dirt can be directly collected in the cup 111. The dust scraping component can be manually driven, automatically driven, or electrically driven. For example, the user can manually move the dust scraping component, or press a button to drive it. Alternatively, a detection device can be installed inside the dust cup to automatically activate the dust scraping component or prompt the user to clean the first filter 12 when there is a large amount of dust on it. This application is not limited to these methods.

[0098] For example, when a lot of dust accumulates on the outside of the first filter 12, the user can feel resistance when the scraper component moves. As the cleaning process continues, the dust on the outside of the first filter 12 is cleaned, and the movement of the scraper component gradually becomes smoother. The user can confirm the cleaning effect by feeling the change in texture during the cleaning process. After the cleaning device 1000 has been working for a period of time, there is a lot of dust inside the cup body 111. When cleaning is needed, the cup lid 112 can be opened by controlling the scraper component, which makes it easier to clean the dust inside the cup body 111.

[0099] In related technologies, users need to hold the cleaning device with one hand and open the lid with the other, which can easily cause dust to fly up and is inconvenient to operate. According to the cleaning device 1000 of this application embodiment, users can operate it with one hand to drive the dust scraping component to automatically open the lid, which brings convenience to users. When cleaning the cup body 111, the dust outlet can be aligned with the dust collection device or garbage bag in advance. When the dust scraping component drives the cup lid 112 to open, the dust in the cup body 111 can directly enter the dust collection device or garbage bag, avoiding dust spillage.

[0100] Combination Figure 2 and Figure 3 In some embodiments of this application, the dust cup 11 further includes a locking part 14. One side of the cup lid 112 is hinged to the cup body 111, and the other side is locked to the cup body 111 by the locking part 14. The dust scraping assembly includes an abutting part 31, which is adapted to abut the locking part 14 to open the cup lid 112, thereby achieving automatic opening and avoiding manual operation. Specifically, the locking part 14 can lock the cup lid 112 when the cup lid 112 closes the dust outlet. When it is necessary to open the lid, the dust scraping assembly abuts the locking part 14 to unlock the locking part 14, allowing the locking part 14 to release the cup lid 112. Thus, one side of the cup lid 112 is connected to the cup body 111, and the other side is separated from the cup body 111, thereby opening the dust outlet.

[0101] Combination Figure 4 In some embodiments of this application, the locking part 14 is rotatably connected to the dust cup 11. The locking part 14 has a trigger end 141 and a locking hook 142. The locking hook 142 hooks the cup lid 112, and the abutting part 31 is adapted to abut the trigger end 141 to unlock the cup lid 112. Specifically, the locking hook 142 has a locked state and an unlocked state. In the locked state, the locking hook 142 can be used to lock the cup lid 112. The trigger end 141 is kinetically connected to the locking hook 142, so that the trigger end 141 can control the state of the locking hook 142. The locking hook 142 can be adjusted from the locked state to the unlocked state, thereby releasing the cup lid 112.

[0102] Combination Figure 1 and Figure 3In some embodiments of this application, the scraping assembly has a first position, a second position, and a third position in the axial direction. The distance between the scraping assembly and the cup lid 112 gradually decreases in the first, second, and third positions, and the cup lid 112 is driven to open in the third position. That is, the scraping assembly can be driven to move between the first and third positions, achieving the effects of scraping and opening the lid. For example, since the first filter 12 is located inside the cup body 111 and the cup lid 112 is located at the end of the cup body 111, when the scraping assembly is controlled to move between the first and second positions, the scraping assembly passes the outside of the first filter 12, achieving the scraping effect; when the scraping assembly is controlled to gradually move towards the third position, the scraping assembly gradually approaches the cup lid 112, allowing the scraping assembly to abut against the locking part. Furthermore, by setting a third position that is closer to the cup lid 112 than the second position, the contact part 31 and the locking part 14 are at a certain distance during the dust removal operation, which can prevent the dust removal component from accidentally opening the cup lid 112 when the user is performing the dust removal operation, thus improving the reliability of use.

[0103] Furthermore, the scraper assembly is configured such that the damping between the first and second positions is less than the damping between the second and third positions, facilitating scraping and allowing the user to easily identify the control status of the scraper assembly. Specifically, the scraper assembly experiences less damping when moving between the first and second positions, allowing the user to control it with less force. The scraper assembly experiences greater damping when moving between the second and third positions, requiring more force for manual operation to open the cup lid 112. This prevents accidental opening and, due to the different damping levels, provides a cues for the user, allowing them to judge the position and status of the scraper assembly based on different tactile feedback.

[0104] Alternatively, a limiting structure can be set between the second and third positions, requiring the scraping component to pass over the limiting structure to contact the locking part 14. This can provide operational feedback to the user and improve the usability.

[0105] In some embodiments of this application, the cleaning device 1000 further includes a damping structure configured to provide damping for the movement of the scraper assembly from a second position to a third position. That is, when the scraper assembly moves between the first and second positions, there is no damping effect, allowing the user to more easily drive the scraper assembly between the first and second positions; when the scraper assembly moves from the second position to the third position, it needs to overcome the damping force. When the scraper assembly reaches the third position, the contact part 31 can trigger the locking part 14 to open the cup lid 112, preventing accidental opening of the cup lid 112 and providing a tactile feedback that distinguishes the operating state of the scraper assembly, thus facilitating the user's judgment of the scraper assembly's working status.

[0106] The first position and the second position are located at both ends of the first filter 12 along the axial direction, so that when the dust scraping assembly moves between the first position and the second position, it can scrape off the dust on the outside of the first filter 12.

[0107] Combination Figure 3 and Figure 5 In some embodiments of this application, the dust-scraping assembly includes a dust-scraping part 22 and an operating part 30. Specifically, the dust-scraping part 22 is sleeved on the outer peripheral surface of the first filter 12 and is adapted to reciprocate along the axial direction of the first filter 12 to scrape dust off the outside of the first filter 12. This improves the dust-scraping effect and occupies less space, which is beneficial for space arrangement. The operating part 30 is drivenly connected to the dust-scraping part 22 and is used to drive the dust-scraping part 22 to move. The operating part 30 is also configured to drive the cup lid 112 to open. In other words, the operating part 30 can both drive the dust-scraping part 22 to move to clean the first filter 12 and open the cup lid 112. Users do not need to manually open the lid, which can avoid dust and secondary pollution, and provide convenience for users.

[0108] Combination Figure 5 More specifically, the scraping part 22 includes a bracket and a ring. The bracket and the ring are connected axially, and the ring is connected to the inner side of the bracket. The ring gradually tapers radially inward to facilitate fitting the outer side of the first filter 12 and improve the scraping effect.

[0109] Combination Figure 3 and Figure 5 In some embodiments of this application, the scraping assembly further includes a guide rod 21 and a support portion 23. The support portion 23 is connected to the scraping part 22 via the guide rod 21, which can support the scraping part 22 axially, preventing the scraping part 22 from shaking during movement and improving the structural and operational stability of the scraping part 22. This allows the scraping part 22 to remove larger contaminants adhering to the outer side of the first filter 12, improving cleaning efficiency and durability. The guide rod 21 extends axially, with one end connected to the scraping part 22. The support portion 23 is connected to the other end of the guide rod 21 and is movably supported on the machine body. The axial extension of the guide rod 21 guides the scraping part 22 to move axially and also provides support between the support portion 23 and the scraping part 22, facilitating force distribution.

[0110] Combination Figure 3 and Figure 5Furthermore, in some embodiments of this application, the cleaning device 1000 further includes a connecting rod 50, with both ends of the connecting rod 50 connected to the guide rod 21 and the operating part 30, respectively, so that the operating part 30 is driveably connected to the dust scraping assembly. That is, the connecting rod 50 can transmit power from the operating part 30 to the guide rod 21, thereby driving the dust scraping part 22 to move. By setting the connecting rod 50, the position of the operating part 30 can be flexibly arranged, facilitating user operation and space arrangement. Optionally, the connecting rod 50 can also be connected to the support part 23, with the operating part 30 drively connected to the support part 23, and movement of the support part 23 can drive movement of the dust scraping part 22. Specifically, the connecting rod may include a first rod portion and a second rod portion. One end of the first rod portion is connected to the guide rod 21 and extends in the same direction as the guide rod 21. The other end of the first rod portion is connected to one end of the second rod portion, and the other end of the second rod portion is connected to the operating part 30. The first rod portion and the second rod portion have an angle between the rods at the connection point or an angle between the extension lines of the extension directions of the first rod portion and the second rod portion. Thus, the setting position of the operating part 30 can be flexibly arranged.

[0111] Combination Figure 2 and Figure 3 In some embodiments of this application, the machine body further includes a motor housing 16, which has a space for accommodating the motor 40. The motor housing 16 and the first filter 12 are arranged axially, and the support portion 23 is sleeved on the outside of the motor housing 16. Specifically, the support portion 23 can be arranged between the motor housing 16 and the outer shell of the cleaning device 1000 to facilitate the accommodation of the support portion 23. The support portion 23 can move axially along the motor housing 16, and when the support portion 23 moves, the scraping portion 22 can also move axially outside the first filter 12.

[0112] Combination Figure 3 In some embodiments of this application, the machine body further includes a guide portion 60, which is disposed between the support portion 23 and the scraping portion 22. The guide portion 60 has a guide hole for the guide rod 21 to pass through and guides the axial movement of the guide rod 21, facilitating the axial extension of the scraping assembly on the machine body, saving space and improving the compactness of the device. In addition, the guide portion 60 can limit the guide rod 21 radially to prevent the scraping assembly from shaking during use.

[0113] Combination Figure 3In some embodiments of this application, the scraping assembly further includes a spring 24. The spring 24 is sleeved on the guide rod 21, and its two ends abut against the guide portion 60 and the support portion 23, respectively. The spring 24 is configured to provide a force to drive the scraping assembly to move away from the cup lid 112, thereby providing a reset force for the scraping portion 22, allowing the scraping portion 22 to automatically reset for user convenience. In use, the operating unit 30 can drive the scraping assembly to move towards the cup lid 112 to scrape dust past the outside of the first filter 12. At this time, the support portion 23 also moves towards the cup lid 112 or the guide portion 60. The spring 24 abuts between the support portion 23 and the guide portion 60 and is compressed. When the driving force disappears, the reset force of the spring 24 can drive the support portion 23 and the scraping portion 22 to reset, thereby simplifying operation.

[0114] Combination Figure 1 In some embodiments of this application, the device further includes an air inlet pipe 18 and a housing. The air inlet pipe 18 and the cup body 111 are both connected to the housing and are arranged side by side and extend in the same direction to facilitate spatial arrangement and improve the compactness of the device structure. Furthermore, the first air inlet 108 of the air inlet pipe 18 and the dust outlet of the cup body 111 face the same direction, which helps to improve the cleaning effect of the cleaning device 1000. Generally, when using the device, the user will align the first air inlet 108 with the area to be cleaned, so that the surface to be cleaned is in contact with the first air inlet 108 to improve the cleaning effect. When this side of the cleaning device 1000 contacts the surface to be cleaned, it can improve the contact effect between the cleaning device 1000 and the surface to be cleaned, making it easier for the user to move the device, facilitating user operation and improving the dust collection effect.

[0115] Combination Figure 1 In some embodiments of this application, the machine body includes a housing, a scraping part 22 is disposed inside the housing, a slide rail 102 is provided on the housing, the slide rail 102 extends axially, and the operating part 30 is slidably engaged with the slide rail 102 axially. The operating part 30 can slide within the slide rail 102 to limit the sliding range of the operating part 30, which helps to improve the stability of operation.

[0116] Combination Figure 1 In some embodiments of this application, the operating part 30 is a U-shape that is fitted onto the air inlet pipe 18, so that the operating part 30 can surround a part of the air inlet pipe 18, which helps to improve the stability of the fit. Both ends of the operating part 30 are connected to the housing and can be slidably fitted, which can improve the stability of the connection between the operating part 30 and the housing, and at the same time help to improve the stability of the operating part 30 when sliding.

[0117] Combination Figure 1In some embodiments of this application, the machine body further includes a handle 70, a support member 80, and a power supply component 90. The power supply component 90 extends axially, and the support member 80 and the handle 70 are axially opposite and spaced apart. The support member 80 is connected to the air inlet pipe 18 and the power supply component 90, respectively. The handle 70 is connected to the housing and the power supply component 90, respectively, which can improve structural stability. Specifically, the power supply component 90 can be used to support the machine body. When the cleaning device 1000 is placed, the power supply component 90 is supported on the table surface for easy storage. The handle 70 is connected between the power supply component 90 and the machine body, which not only provides support but also allows the user to reach into the gap between the power supply component 90 and the machine body, making it easy for the user to hold the cleaning device 1000 and move it for cleaning. Furthermore, when the user needs to use the dust scraping component, they can directly pull the operating part 30 connected to the air inlet pipe 18 forward with their fingers, which is convenient for one-handed operation.

[0118] Combination Figure 2 The power supply component 90 also contains a battery to provide storage space for the battery, so that the user can use the battery's energy to drive the cleaning device 1000 in the event of a power outage. Furthermore, placing the battery inside the power supply component 90 helps to improve the stability of the power supply component 90, resulting in a lower center of gravity for the cleaning device 1000, which is conducive to stable placement.

[0119] Combination Figure 3 In some embodiments of this application, the body further includes a second filter 13, which extends axially. One end of the second filter 13 has a handle 131 located near the cup lid 112 and is adapted to pass through the cup lid 112 and be detachably and sealingly connected to it. This allows the user to pull out the second filter 13 axially via the handle 131 without opening the dust cup 11 lid 112, facilitating cleaning and assembly, and providing convenience for the user. Specifically, the second filter 13 is located in front of the motor 40 in the airflow path. During use, the airflow first enters the second filter 13 for filtration before flowing towards the motor 40, improving the cleaning effect and protecting the motor 40. Therefore, to improve the filtration effect and facilitate quick disassembly and cleaning of the second filter 13, a handle 131 can be provided on the second filter 13 and engage with the dust cup 11 to improve assembly efficiency. In use, the second filter 13 can be inserted into the machine body. The machine body has a snap-fit ​​part, which can improve the stability of the installation of the second filter 13. A sealing ring is provided between the second filter 13 and the machine body and the cup lid 112. Alternatively, after inserting the second filter 13, rotate the second filter 13 to find the docking part, and the second filter 13 abuts or snaps into the docking part.

[0120] Furthermore, the machine body also includes a third filter 15, which is located at the rear of the motor 40 in the airflow path. During use, the airflow flows toward the motor 40 and is discharged from the third filter 15, which helps to improve the cleanliness of the discharged gas and avoid secondary pollution.

[0121] A cleaning apparatus 1000 according to a specific embodiment of this application is described below with reference to the accompanying drawings.

[0122] Combination Figures 1 to 5 The cleaning device 1000 according to an embodiment of this application includes: a body, a dust cup 11 connected to the body, a handle 70, a motor 40, a power supply assembly 90, an air inlet pipe 18, a first filter 12, and a second filter 13 and a third filter 15 connected to the motor 40. In this embodiment, the cleaning device 1000 adopts side air intake, so the first air inlet 108 is located on one side of the dust cup 11. The second filter 13 and the third filter 15 are located in front of and behind the motor 40 respectively in the airflow path for filtering the airflow. The third filter 15 may overlap with the motor 40 in space depending on the actual situation. The dust cup 11, the motor 40, and the third filter 15 are arranged sequentially along the longitudinal axis of the dust cup 11, and the second filter 13 is located inside the dust cup 11. The power supply component 90 is located at the bottom of the cleaning device 1000, supporting the entire device. The handle 70 is positioned between the motor 40 and the power supply component 90. The axis of the handle 70 does not pass through the motor 40. The motor 40 is positioned further back relative to the axis of the handle 70, with the center of gravity further back to avoid extra strain on the user's wrist and improve usability. The cleaning device 1000 has a relatively far end and a near end. The first air inlet 108 is located at the far end, and the third filter 15 is located at the near end. Figure 2 The remote end can be the front end, and the near end can be the back end.

[0123] The dust cup 11 includes a cup body 111 and a cup lid 112 for emptying dust. A first filter 12 is disposed inside the cup body 111. The first filter 12 can be a filter screen with multiple through holes on its surface for filtering larger dust particles. A multi-cone cyclone separator may also be provided inside the dust cup 11. The multi-cone cyclone separator includes multiple small cones arranged around the dust cup 11 and downstream of the first filter 12 for further filtration and to improve the filtration effect. The dust cup 11 also has a locking part 14 for locking and unlocking the cup lid 112.

[0124] Combination Figure 3 The cleaning device 1000 also includes a dust scraping assembly, which includes an operating part 30, a connecting rod 50 connected to the operating part 30, a support part 23 fixed inside the machine body, and a dust scraping part 22 connected to the support part 23. The dust scraping part 22 abuts against the outer wall of the first filter 12 and is located at the end of the first filter 12 near the motor 40 in the initial position.

[0125] Specifically, three guide rods 21 are spaced apart between the support part 23 and the scraping part 22 for connection and to transmit the movement of the operating part 30. One end of the connecting rod 50 is connected to the operating part 30, and the other end of the connecting rod 50 is connected to at least one of the guide rods 21, for driving the scraping part 22 to move when the connecting rod 50 moves. The support part 23 is arranged around the periphery of the motor housing 16 and can move along the motor housing 16 when the operating part 30 is pushed. Since the scraping part 22 is connected to the support part 23 through the guide rods 21, when the support part 23 moves along the motor housing 16, the scraping part 22 moves in the same direction and scrapes away the dust around the first filter 12.

[0126] Furthermore, a spring 24 is fitted onto the guide rod 21. During dust scraping, the movement of the support part 23 causes the spring 24 to compress. When the dust scraping action ends, the restoring force of the spring 24 causes the dust scraping part 22 to automatically return to its original position. The operating part 30 is located below the dust cup 11. This position makes it more convenient for the user to push and pull, making the pushing and pulling action smoother.

[0127] According to the cleaning device 1000 of the present application embodiment, the dust cup 11 remains stationary during the dust scraping process, and only the dust scraping part 22 moves inside the dust cup 11. The principle of dust scraping is as follows: During dust scraping, the user pushes the operating part 30, which drives the connecting rod 50 to move. The movement of the connecting rod 50 drives the support part 23 to move along the periphery of the motor cover 16. The movement of the support part 23 causes the dust scraping part 22 to contact the periphery of the first filter 12 to achieve dust scraping. At this time, the spring 24 is compressed. The pushing and pulling action of dust scraping can be performed multiple times. By repeatedly moving the dust scraping part 22, the dust on the outside of the first filter 12 can be scraped more cleanly. When the dust scraping operation ends, under the elastic restoring force of the spring 24, the operating part 30 returns to the initial position, which in turn drives the dust scraping part 22 to move to the initial position. By setting up the dust scraping component, the dust and dirt accumulated on the first filter 12 can be scraped off each time the dust is emptied, and regular cleaning can be performed to avoid clogging of the filter screen and avoid affecting the suction power of the cleaning device 1000. Moreover, there is no need to disassemble the dust cup 11. The operation is simple and convenient, and the dust removal effect is good.

[0128] Furthermore, the dust scraper assembly is not connected or mated to the outer or inner wall of the dust cup 11. The entire inner wall of the dust cup 11 is a complete annular wall. This design ensures the continuity of airflow inside the dust cup 11 and prevents the airflow from being disrupted.

[0129] Furthermore, the operating unit 30 also includes an abutment part 31, which is located at the end of the connecting rod 50 near the operating unit 30. When the dust scraper 22 moves to the end of its stroke (third position) or near the end of its stroke (third position), the abutment part 31 presses against the locking part 14 of the dust cup 11 to unlock it, causing the cup lid 112 to open. After the dust scraping operation is completed or during the operation, the cup lid 112 can be opened to perform dust scraping and emptying operations. At this time, the user will operate towards the trash can. Since this application has a horizontal structure for the dust cup 11, the trash is directly poured into the trash can from the front end of the dust cup 11, avoiding dust spillage and preventing dust from falling back onto the cleaned ground. At the same time, the user only needs to push the operating unit 30 and does not need to touch the vicinity of the cup lid 112, avoiding contact with dust and improving the user experience.

[0130] In actual use, the airflow path of the whole machine is as follows: the airflow enters the air inlet pipe 18 from the first air inlet 108, and the dust and air enter the dust cup 11 from the side. After being filtered by the first filter 12, the dust falls into the first dust collection space. The airflow containing a small amount of dust continues to enter the multi-cone cyclone separator for filtration. The fine dust after filtration falls into the second dust collection space. The airflow continues to enter the second filter 13 for filtration and flows towards the motor 40. Finally, after passing through the third filter 15, it is discharged from the air outlet.

[0131] Specifically, dust and air enter the cleaning device through the suction inlet and tangentially enter the dust cup 11 along the air duct. Under centrifugal force, the dust and debris spiral down the wall of the dust cup 11 into the first dust collection space. The filter screen has a flange at a certain angle to the horizontal, which prevents dust that has entered the bottom by centrifugal force from re-entering the multi-cone cyclone separator, effectively reducing the total amount of dust entering the multi-cone cyclone separator. Some dust passes through the filter screen and enters the multi-cone cyclone separator. Similarly, under centrifugal force, the dust spirals down the wall of the multi-cone cyclone separator to the second dust collection space at the bottom. The gas, at the dust-air separation port, enters the second filter 13 through the porous air passage, then enters the motor 40, and finally passes through the third filter 15 before being discharged. This case, by setting up two cyclone filters and using a multi-cone cyclone mechanism for the second filtration stage, greatly increases the separation efficiency of dust and air, reduces the frequency of filter cleaning, and extends the filter's service life.

[0132] The second filter 13 is located inside the first filter 12. A handle 131 is provided at the end of the second filter 13 for removing it along the longitudinal axis of the dust cup 11. The handle 131 is located near the cup lid 112, and the second filter 13 is disassembled in the direction away from the cup lid 112. The third filter 15 can be disassembled rearward, which facilitates cleaning of both the second and third filters 13. The second filter 13 is coaxially arranged with the first filter 12. The second filter 13 includes filter cotton and a filter support. After being filtered by the filter cotton, the airflow enters the interior through several through holes in the filter support and flows towards the motor 40 from the internal channel. As previously stated, to allow for quick disassembly and cleaning of the second filter 13, the second filter 13 is located in the middle of the dust cup 11, and is connected to the fan assembly above via a sealing ring. The gas after dust-gas separation enters the second filter 13 through the porous air passage, then enters the motor 40, and is discharged. Usually, a small amount of fine dust will adhere to the outer wall of the second filter 13. When the second filter 13 needs to be cleaned, simply twist the handle 131 of the second filter 13 at the opening at the bottom of the dust cup 11 and pull it out. After cleaning, it can be reassembled in the same way. In this way, the second filter 13 can be quickly cleaned or replaced without disassembling any other parts, greatly improving user convenience and satisfaction.

[0133] A power switch is located on the handle 70, either on the housing or where the screen is located. The cleaning device 1000 also has a rear cover, with the display screen facing rearward and located on the rear cover. When disassembling, first remove the rear cover, and then remove the third filter 15 for cleaning.

[0134] Combination Figures 6 to 12This application also proposes a floor brush 200 for a cleaning device 1000. According to some embodiments of this application, the floor brush 200 includes: a main body 20c and a cover 20d. The cover 20d is connected to the main body 20c and is rotatable about the axis of the cover 20d. The cover 20d has a first position and a second position in the rotation direction. The cover 20d is locked to the main body 20c in the first position and is unlocked from the main body 20c and detachable in the second position. The cover 20d has a receiving cavity 202 inside. Specifically, the accommodating cavity 202 can be used to accommodate the roller brush 241. The main body 20c and the cover 20d are detachably connected. When the cover 20d is locked onto the main body 20c, the user can use the floor brush 200 for cleaning. When the cover 20d is unlocked from the main body 20c, the cover 20d separates from the main body 20c, the accommodating cavity 202 opens, and the user can maintain the main body 20c, the cover 20d, and the roller brush 241. It also facilitates the user's disassembly of the roller brush 241. More specifically, by connecting the cover 20d and the main body 20c, the cover 20d or the main body 20c can rotate along the axis of the cover 20d, thereby unlocking and locking the floor brush 200. The rotational engagement improves the flexibility of assembly. Thus, the relative position requirements between the cover 20d and the main body 20c are lower during assembly, simplifying the assembly steps and facilitating rapid assembly.

[0135] According to the embodiments of this application, the floor brush 200 of the cleaning device is provided with a rotatable main body 20c and a cover 20d. The floor brush 200 can be locked and unlocked by rotation, so that the user can open the receiving cavity 202 for easy cleaning and replacement of the roller brush 241. This simplifies the structure of the floor brush 200 and makes it easy for the user to disassemble.

[0136] Combination Figure 7 In some embodiments of this application, the main body 20c includes a base 211 and a first mating part 212 disposed on the base 211. One end of the cover 20d is rotatably fitted onto the first mating part 212 so that the sleeve 221 can be installed on the base 211. Specifically, the mating of the base 211 and the cover 20d by the fitting method facilitates assembly, improves assembly stability, and simplifies the structure.

[0137] Combination Figure 6 and Figure 7In some embodiments of this application, the cover 20d includes a sleeve 221 and a fixing part 222. One end of the sleeve 221 is open 201 and rotatably sleeved on the outside of the first mating part 212. Specifically, the sleeve 221 is sleeved on the outside of the first mating part 212 so as to fix the cover 20d on the seat 211 of the main body 20c. The sleeve 221 and the first mating part 212 can partially overlap, which is beneficial to improve the mating stability. It also makes it easy for the sleeve 221 to rotate on the first mating part 212 so as to adjust the position of the cover 20d by rotation, thereby realizing locking and unlocking. The operation is simple and the stability during assembly is high.

[0138] Furthermore, the fixing part 222 is connected to the sleeve 221. When the cover 20d is in the first position, the fixing part 222 is fixedly connected to the main body 20c to lock the cover 20d and the main body 20c. When the cover 20d is in the second position, the fixing part 222 is separated from the main body 20c, which allows the floor brush 200 to be disassembled, facilitating the assembly of the roller brush 241 or cleaning operations. Specifically, the roller brush 241 is located in the receiving cavity 202. By separating the sleeve 221 from the first mating part 212, the receiving cavity 202 can be opened, allowing direct replacement or cleaning of the roller brush 241. This simplifies the structure of the floor brush 200, facilitates its disassembly, and provides convenience for the user.

[0139] According to the embodiments of this application, the floor brush 200 of the cleaning device is provided with a detachably connected sleeve 221 and a first mating part 212, which allows the user to open the receiving cavity 202 by separating the sleeve 221 and the first mating part 212, making it convenient to clean and replace the roller brush 241, simplifying the structure of the floor brush 200 and making it easy for the user to disassemble.

[0140] In practical applications, the roller brush 241 of the cleaning device can be installed on the base 211. When the sleeve 221 is assembled with the first mating part 212, the opening 201 of the sleeve 221 faces the roller brush 241 and the first mating part 212. The sleeve 221 can sleeve the roller brush 241 along the axial direction of the roller brush 241 to house the roller brush 241 in the receiving cavity 202. When the sleeve 221 is connected with the first mating part 212, the floor brush 200 can be assembled. When it is necessary to clean or replace the roller brush 241, the sleeve 221 can be separated from the first mating part 212 to open the receiving cavity 202 and expose the roller brush 241, which facilitates the cleaning or replacement of the roller brush 241 and provides convenience for users and daily maintenance.

[0141] According to some embodiments of the present application, the floor brush 200 has a first mating part 212 as a boss, and the opening 201 end of the sleeve 221 extends into a sleeve portion in the direction facing the seat 211. The sleeve portion is adapted to be sleeved on the outer periphery of the boss to realize the sleeve 221 and the seat 211 sleeve engagement. In this way, at least a part of the first mating part 212 and the sleeve portion overlap or are stacked. The boss can also provide an abutment surface or mating surface for the sleeve portion, which can improve the stability of assembly and structural stability, and can also improve the sealing effect after assembly.

[0142] Combination Figures 6 to 8 In some embodiments of this application, the fixing part 222 is connected to one end of the sleeve 221 and detachably connected to the main body 20c. By providing the fixing part 222 at the other end of the sleeve 221, the sleeve 221 can be fixed at the end away from the seat 211. After the fixing part 222 is connected to the main body 20c, the stability after assembly can be improved. That is, one end of the sleeve 221 can be detachably connected to the seat 211, and the fixing part 222 connected to the other end of the sleeve 221 can be connected to the main body 20c. Thus, the opposite sides of the cover 20d can be detachably connected to the opposite sides of the main body 20c, which facilitates the direct separation and assembly of the main body 20c and the cover 20d, and also improves the stability after assembly.

[0143] Combination Figure 6 and Figure 7 In some embodiments of this application, the main body 20c further includes a mounting portion 213, which is connected to the base 211 and adapted to be connected to the fixing portion 222. Thus, the fixing portion 222 of the cover 20d can be connected to the mounting portion 213 of the main body 20c, which can further improve the stability when the cover 20d is connected to the main body 20c.

[0144] In some embodiments of this application, the mounting portion 213 extends in a direction parallel to the rotation axis of the cover 20d. One end of the mounting portion 213 is connected to the base 211, and the other end is used to fix the fixing portion 222. Thus, one end of the mounting portion 213 is connected to the base 211, and the other end is detachably connected to the fixing portion 222. The mounting portion 213 and the base 211 are arranged side by side, and the sleeve 221 and the fixing portion 222 are arranged side by side. The sleeve 221 is opposite to the first mating portion 212, and the mounting portion 213 is opposite to the fixing portion 222. During assembly, the opposite sides of the main body 20c and the cover 20d can be detachably connected, which can improve the stability after assembly. Moreover, the staggered arrangement of the connection positions can facilitate the arrangement and is not restricted during assembly.

[0145] More specifically, the mounting portion 213 is columnar, and a motor (not shown in the figure) may be installed inside the mounting portion 213. The motor can be used to drive the roller brush 241 on the base 211 to rotate. Figure 8On one side (or the left side) of the floor brush 200, the mounting part 213 and the base 211 can be arranged side by side in the front-to-back direction, which can shorten the assembly distance. The power of the motor can be directly transmitted to the base 211 connected to the mounting part 213 through a transmission device or gear to drive the roller brush 241 to rotate, which helps to improve the structural compactness and avoid energy waste. On the other side (or the right side) of the floor brush 200, the sleeve 221 and the fixing part 222 are connected in the front-to-back direction. The sleeve 221 is used to accommodate the roller brush 241, and the fixing part 222 is used to connect with the mounting part 213, so that both ends of the floor brush 200 can be disassembled, which helps to improve assembly flexibility and stability.

[0146] Combination Figure 7 and Figure 10 In some embodiments of this application, the sleeve 221 is rotatable between a first position and a second position around its axis. In the first position, the fixing part 222 is engaged with the mounting part 213 to assemble the fixing part 222 and the mounting part 213. In the second position, the fixing part 222 is separated from the mounting part 213 to disassemble the fixing part 222 and the mounting part 213. Thus, the cover 20d can be disassembled by rotating the sleeve 221, which facilitates the user's disassembly operation. Specifically, after the opening 201 end of the sleeve 221 is fitted onto the first mating part 212, the sleeve 221 can rotate around the axis of the sleeve 221 with the first mating part 212 as the fulcrum. When the sleeve 221 rotates, the fixing part 222 connected to the sleeve 221 also rotates. When the sleeve 221 rotates to the first position, the fixing part 222 is engaged with the mounting part 213 to realize the assembly of the floor brush 200. When the sleeve 221 rotates from the first position to the second position, the fixing part 222 is separated from the mounting part 213, and the opening 201 end of the sleeve 221 leaves the first mating part 212, so that the cover 20d can be disassembled. In other words, with the above structure, the user only needs to connect the sleeve 221 to the base 211 and rotate the sleeve 221 to fasten the fixing part 222 and the mounting part 213 to install the floor brush 200; conversely, by rotating the sleeve 221 until the fixing part 222 and the mounting part 213 are separated, the sleeve 221 can be separated from the base 211, and the floor brush 200 can be disassembled, which simplifies the structure and makes it easier for the user to perform disassembly and assembly operations.

[0147] Combination Figure 7 and Figure 9 In some embodiments of this application, the mounting portion 213 is provided with a mating portion 214, which can be used to cooperate with the fixing portion 222 to improve the tightness and stability of the connection between the mounting portion 213 and the fixing portion 222. Specifically, when the cover 20d is in the first position, the fixing portion 222 abuts against the mating portion 214, and when the cover 20d is in the second position, the fixing portion 222 separates from the mating portion 214.

[0148] Combination Figure 7 and Figure 9 In some embodiments of this application, the mounting part 213 is provided with a mating part 214 protruding from it, and the fixing part 222 is provided with a second mating part 224. The mating part 214 is sleeved on the second mating part 224 so that the mounting part 213 can be connected to the fixing part 222.

[0149] Furthermore, combined Figure 11 and Figure 12 In some embodiments of this application, the mating part 214 is provided with one of the first positioning block 2141 and the first positioning groove 2241, and the fixing part 222 is provided with the other of the first positioning block 2141 and the first positioning groove 2241. When the cover 20d is in the first position, the first positioning block 2141 and the first positioning groove 2241 engage to lock the cover 20d circumferentially. This can limit the circumferential movement after the mounting part 213 and the fixing part 222 are connected, preventing circumferential rotation and improving the stability after assembly. That is, positioning blocks or positioning grooves can be provided on the mating part 214 and the fixing part 222 according to the actual situation to improve the stability when the mating part 214 and the fixing part 222 are connected, that is, the positioning groove and the positioning block can be interchanged. Specifically, in conjunction with Figure 7 and Figure 9 The mating part 214 is provided with a first positioning block 2141, and the fixing part 222 is provided with a first positioning groove 2241. The first positioning block 2141 is adapted to be embedded in the first positioning groove 2241. In this way, when the first positioning block 2141 is embedded in the first positioning groove 2241, the first positioning groove 2241 can circumferentially limit the mounting part 213.

[0150] Furthermore, in some embodiments of this application, the mating part 214 is provided with a second positioning block 2142, and the fixing part 222 is provided with a second positioning groove 2242. When the cover 20d is in the first position, the second positioning block 2142 is embedded in the second positioning groove 2242 and locks the cover 20d along the axial direction to achieve axial limiting, which can improve the stability after assembly.

[0151] Specifically, to further improve the positioning and fixing effect, the first positioning block 2141 and the second positioning block 2142 can be arranged at intervals, and / or the first positioning block 2141 and the second positioning block 2142 can be staggered on the mating part 214 to improve the positioning effect. More specifically, the second positioning block 2142 can be in the form of a triangular protrusion to form a slope on the surface of the positioning block, so that the second positioning block 2142 can easily slide into the second positioning groove 2242. In this way, by providing the first positioning block 2141 and the second positioning block 2142 on the mating part 214 respectively, and providing the first positioning groove 2241 and the second positioning groove 2242 correspondingly on the fixing part 222 to cooperate with the first positioning block 2141 and the second positioning block 2142, the mounting part 213 and the fixing part 222 can be limited in multiple directions after assembly, thereby improving the stability after assembly.

[0152] Combination Figure 9 and Figure 12 According to the embodiments of this application, the floor brush 200 has a notch 205 on the fixing part 222, and a second mating part 224 protrudes from the notch 205 in the direction facing the mounting part 213. The second mating part 224 can be configured with a first positioning groove 2241 and a second positioning groove 2242 for mating with the mating part 214. The second mating part 224 can also be configured with a hollow structure to reduce the weight of the floor brush 200. That is, after the opening 201 end of the sleeve 221 is sleeved on the base 211, the rotation of the sleeve 221 can rotate the fixing part 222 to the first position, thereby making the fixing part 222 and the mounting part 213 lock together to achieve a locking effect, so as to realize the fixed connection between the cover 20d and the main body 20c.

[0153] In some embodiments of this application, combined with Figure 7 The mounting part 213 is provided with a first hook 215, and the fixing part 222 is provided with a first protrusion 225. The first hook 215 and the mating part 214 are arranged at intervals, and the first protrusion 225 and the second mating part 224 are arranged at intervals. The first hook 215 and the first protrusion 225 cooperate to connect the mounting part 213 and the fixing part 222.

[0154] Specifically, in combination Figure 7 and Figure 9The first hook portion 215 and the first protrusion 225, when engaged, can further improve the positioning and connection effect between the mounting portion 213 and the fixing portion 222. Furthermore, the first hook portion 215 and the first protrusion 225 are spaced apart from the aforementioned mating portion 214 and the second mating portion 224, allowing for fixed connections at multiple locations to improve the structural stability after assembly. In addition, the first hook portion 215 and the first protrusion 225 also serve a positioning and guiding function. The first hook portion 215 and the first protrusion 225 can be positioned close to the first location. When the user rotates the sleeve 221, the first hook portion 215 and the first protrusion 225 engage, improving the positioning effect.

[0155] In some embodiments of this application, the main body 20c is provided with a locking part, and the fixing part 222 is also provided with a locking member. The locking member is movably disposed on the fixing part 222 to lock and unlock the locking part. When the locking member engages with the locking part, the cover 20d is locked, thereby realizing the assembly of the floor brush 200. By locking the main body 20c and the cover 20d, a stable state can be maintained after assembly. When the locking member engages with the locking part, the cover 20d can rotate to unlock the cover 20d and disassemble the floor brush 200. Specifically, when the user needs to disassemble the floor brush 200, it is only necessary to unlock the locking member, so that the locking member releases the locking part to achieve unlocking. After unlocking, the main body 20c and the cover 20d can be separated, thereby disassembling the floor brush 200, which simplifies the structure and operation. In practical applications, the locking member can be unlocked by flicking or pressing, etc., and this application is not limited to this. In other words, the locking element and the locking part can be separate structures, or they can be the aforementioned first positioning block 2141 and first positioning groove 2241. That is, the mating part 214 is provided with the first positioning groove 2241, and the fixing part 222 is provided with the first positioning block 2141. In this case, the corresponding locking element controls the movement of the first positioning block 2141 relative to the first positioning groove 2241. The locking element is movable and is directly or indirectly connected to the first positioning block 2141 to control its movement. When unlocking, the first positioning block 2141 disengages from the first positioning groove 2241. Similarly, the locking element can also be the aforementioned second positioning block 2142 and second positioning groove 2242, with the same principle.

[0156] Combination Figure 7 and Figure 10 In some embodiments of this application, the mounting part 213 is further provided with an air intake 206, and the sleeve 221 is provided with an air outlet 203. In the first position, the air intake 206 and the air outlet 203 are connected to form an airflow cavity. Specifically, when the sleeve 221 is rotated to the mounting position, the air intake 206 and the air outlet 203 are connected to form an airflow cavity, which facilitates airflow and makes it easier for the user to perform cleaning work.

[0157] Furthermore, combined Figure 7In some embodiments of this application, a second hook 2131 is provided at the air intake 206, and a second protrusion 223 is provided at the air outlet 203. The second hook 2131 is adapted to cooperate with the second protrusion 223 to fasten the fixing part 222 and the mounting part 213 at a first position. This can position the air intake 206 and the air outlet 203 at the docking position, thereby improving the stability of the assembly. The air intake 206 and the air outlet 203 can be sealed together to prevent airflow leakage and improve the suction power of the cleaning device.

[0158] Alternatively, the floor brush 200 can be fixed by the cooperation of the second protrusion 223 and the second hook 2131. The user can remove it by holding the cover 20d from the side and forcing the second protrusion 223 and the second hook 2131 apart.

[0159] In practical applications, the fixing method of the floor brush 200 can be adjusted according to the actual situation. For example, it can be fixed only by the cooperation between the second protrusion 223 and the second hook 2131; or it can be fixed only by the cooperation between the first positioning block 2141 and the first positioning groove 2241; or it can be fixed only by the cooperation between the second positioning block 2142 and the second positioning groove 2242. Of course, it can also be fixed by any combination of at least two of the above three methods, and this application is not limited to this.

[0160] Combination Figure 8 and Figure 10 In some embodiments of this application, a base plate 230 is connected to the bottom of the cover 20d. The base plate 230 can mate with the working surface to fit the working surface and improve the cleaning effect. Specifically, the base plate 230 is provided with a hollow groove 207. A part of the hollow groove 207 is used to expose the roller brush 241, and the other part is connected to the receiving cavity 202. Dirt in the working surface can enter the receiving cavity 202 through the hollow groove 207. The roller brush 241 can also be used to tap or brush the working surface to improve the cleaning effect on the working surface.

[0161] Combination Figures 6 to 10 The cleaning device according to the embodiments of this application includes: the aforementioned floor brush 200 and roller brush 241. A cover 20d is sleeved on the outside of the roller brush 241, and the cover 20d is detachably connected to the main body 20c. By setting the aforementioned floor brush 200, the connected cover 20d and main body 20c can be directly disassembled, so that the user can open the receiving cavity 202 by separating the cover 20d and the main body 20c, which facilitates the user to replace the roller brush 241 and simplifies the disassembly structure and disassembly operation.

[0162] Optionally, the cleaning device can be equipped with multiple roller brushes 241, each with different functions, allowing users to easily replace the roller brushes 241 according to their needs to improve the cleaning effect. For example, the cleaning device can have a cleaning brush and a mite-removing brush to achieve different cleaning effects. Specifically, users can remove the base 211 and the sleeve 221 to open the receiving cavity 202 and expose the roller brushes 241 for replacement. This also allows users to directly clean the receiving cavity 202.

[0163] Combination Figure 7 and Figure 9 According to the cleaning device of this application embodiment, the roller brush 241 is cantilevered and connected to the base 211. The roller brush 241 has a fixed end and a free end. The fixed end of the roller brush 241 is connected to the base 211, and the free end of the roller brush 241 extends toward the sleeve 221. The roller brush 241 has a spiral structure, and the roller brush 241 can tap the working surface during rotation to remove mites. Specifically, the roller brush 241 is a conical roller brush 241 with one end fixed and the other end free, which can improve the cleaning degree of the roller brush 241 on hair. The airflow outlet is close to the free end of the roller brush 241, which can prevent hair from getting tangled on the roller brush 241 and make it easier for the user to clean the cleaning device.

[0164] Of course, users can also choose not to install the roller brush 241 and use only the cleaning device for vacuuming.

[0165] A specific embodiment of the cleaning device and floor brush 200 of this application is described below with reference to the accompanying drawings.

[0166] Combination Figures 6 to 12 The cleaning device includes a floor brush 200 and a roller brush 241. The floor brush 200 includes a main body 20c and a cover 20d. The main body 20c includes a base 211, on which the roller brush 241 is rotatably mounted. The cover 20d includes a sleeve 221, which is sleeved on the outside of the roller brush 241 and detachably connected to the base 211. The cover 20d also includes a fixing part 222, which is connected to the sleeve 221. The main body 20c also includes a mounting part 213, which is connected to the base 211 and coaxially connected to the fixing part 222. A motor is provided inside the mounting part 213, which provides power for the rotation of the roller brush 241.

[0167] During assembly, sleeve 221 is aligned from right to left (see...) Figure 7The motion cover is located around the roller brush 241. The base 211 has a first mating part 212. The opening 201 end of the sleeve 221 is sleeved on the first mating part 212. The first mating part 212 is in contact with the end face of the opening 201. When the sleeve 221 is rotated to the first position or the locked position, the fixing part 222 connected to the sleeve 221 and the locking part of the mounting part 213 connected to the base 211 cooperate to lock the cover 20d and the main body 20c.

[0168] The pivot point of the cover 20d is the mating surface formed by the first mating part 212 and the mating surface formed by the opening 201. Rotation is performed with the above mating surfaces as the pivot point. After the cover 20d is disassembled by the rotational movement, the roller brush 241 can be cleaned easily. At this time, the roller brush 241 can be cleaned without disassembling it, which provides convenience for users. The structure is simple and easy to operate.

[0169] Furthermore, the mounting part 213 is provided with a main airflow inlet, namely the air intake 206, and the sleeve 221 is provided with an air outlet 203. When the sleeve 221 rotates to the first position or the locked position, the air intake 206 and the air outlet 203 can be sealed together to form an airflow cavity, thereby improving the cleaning effect.

[0170] Optionally, the roller brush 241 is conical, and the roller brush 241 guides the movement of dust through a spiral structure, thereby improving the efficiency of dust collection. The motor is located at the rear of the roller brush 241. Of course, in other embodiments, the motor can also adopt a built-in structure design, and the motor can be at least partially built into the roller brush 241.

[0171] Combination Figures 13 to 16 According to some embodiments of this application, the floor brush 200 includes a housing 210, a roller brush 241, and an optical device 250. The roller brush 241 is rotatably disposed within the housing 210. The optical device 250 is disposed on one side of the roller brush 241. The optical device 250 includes a light emitter 2501 and a beam assist device 2502. The beam assist device 2502 is used to receive light emitted from the light emitter 2501 and guide the light to the surface to be cleaned, thereby illuminating the dirt on the area of ​​the surface to be cleaned. The area is fan-shaped, and the fan includes a first edge 2503 and a second edge 2504. Compared with the second edge 2504, the first edge 2503 is adjacent to the roller brush 241, and the second edge 2504 extends in a direction away from the roller brush 241. The included angle between the second edge 2504 and the front edge of the roller brush 241 is α, and α satisfies the relationship: 50°≤α≤68°.

[0172] The term "dirt" includes dust, hair, debris, litter, and other unwanted substances that may be located on surfaces to be cleaned, such as floor surfaces, carpet surfaces, or raised surfaces such as countertops, tables, benches, or shelves.

[0173] Specifically, the housing 210 provides a space to accommodate dirt and the roller brush 241. The roller brush 241 is rotatably connected to the housing 210 and rotates along its central axis on the surface to be cleaned. The roller brush 241 is typically an elongated cylinder with bristles extending radially outward from its outer edge. Specifically, the cleaning device 1000 can be a vacuum cleaner. When the vacuum cleaner starts working, a negative pressure is created on it, causing air to flow below the housing 210 and around the floor brush 200. This helps the vacuum cleaner lift and suck up dirt and dust from the surface to be cleaned, and then carries the dirt and dust from the opening in the housing 210 through the floor brush 200 to the dirt-accommodating space.

[0174] Furthermore, the beam assist device 2502 is used to receive light emitted from the light source 2501 and guide the light to the surface to be cleaned on the floor brush 200. This illuminates dirt on the flat surface area to be cleaned. The illumination range of the optical device 250 is fan-shaped, with the first edge 2503 adjacent to the front edge of the roller brush 241 and the second edge 2504 extending away from the roller brush 241. The angle between the second edge 2504 and the front edge of the roller brush 241 ranges from 45° to 75°. Thus, the first edge 2503 and the second edge 2504 are longer than the maximum width of the floor brush 200. This ensures effective illumination of dirt on the nearest surface area to be cleaned while maximizing illumination of dirt on the surface area directly in front of the floor brush 200. This allows the user to see the dirt in the area more clearly and to choose the appropriate cleaning strategy, thereby improving the cleaning effect of the vacuum cleaner and enhancing the user experience. For example, the included angle α between the second edge 2504 and the front edge of the brush 241 can be 45°, 60° and 75°, but is not limited thereto.

[0175] Therefore, by designing the 200-degree brush, users can see the dirt more clearly when cleaning the surface, and the user's visual experience is softer.

[0176] According to some alternative embodiments of this application, in combination with Figure 15The angle α satisfies the relationship: 50° ≤ α ≤ 68°. Specifically, the angle between the second edge 2504 and the front edge of the roller brush 241 ranges from 50° to 68°. This allows for effective illumination of dirt on the nearest surface area to be cleaned while further expanding the illumination range of dirt on the surface area directly in front of the floor brush 200, thereby improving the visibility of dirt on the surface to be cleaned. For example, the angle α between the second edge 2504 and the front edge of the roller brush 241 can be 50°, 60°, or 68°, but is not limited to these.

[0177] According to some alternative embodiments of this application, in combination with Figure 15 and Figure 16 A portion of the sector is located below the roller brush 241, and another portion is located in front of the front edge of the roller brush 241. Specifically, the first edge 2503 of the sector extends approximately parallel to the front edge of the roller brush 241, and the first edge 2503 is closer to the central axis of the roller brush 241 than the front edge of the roller brush 241. This allows the area irradiated from the first edge 2503 to overlap with the front edge of the roller brush 241, thus increasing the irradiation area on the surface to be cleaned and ensuring that the surface to be cleaned below the arc segment corresponding to the front edge of the roller brush 241 is irradiated, thereby improving the visibility of dirt on the surface to be cleaned.

[0178] According to some alternative embodiments of this application, in combination with Figure 16 As shown, the divergence angle β of the light beam emitted by the optical device 250 in the vertical plane satisfies the relationship: 2° ≤ β ≤ 20°. Specifically, the smaller divergence angle of the light beam emitted by the optical device 250 in the vertical plane improves the user's visual detection of dirt on the surface to be cleaned. Visually, the light scattered by the dirt appears brighter than the light reflected from the surface, and a relatively long shadow is cast behind the dirt, creating a clear contrast with the relatively brightly lit dirt. This lighting effect effectively helps the user identify dirt on the surface and increases the likelihood that the floor brush 200 will capture dirt as it moves back and forth across the surface, reducing the time spent cleaning and thus reducing power consumption. For example, the divergence angle β of the light beam emitted by the optical device 250 in the vertical plane can be 2°, 10°, or 20°, but is not limited to these.

[0179] Specifically, β satisfies the relationship: 2° ≤ β ≤ 9°. The divergence angle of the light beam emitted by the optical device 250 in the vertical plane ranges from 2° to 9°. This allows the light to illuminate dirt at a shallower angle, further improving the user's visual detection of dirt on the surface to be cleaned. It effectively helps the user identify dirt on the surface and increases the likelihood that the floor brush 200 will capture dirt as it moves back and forth across the surface, reducing the time spent cleaning and thus reducing power consumption. For example, the divergence angle β of the light beam emitted by the optical device 250 in the vertical plane can be 2°, 6°, or 9°, but is not limited to these.

[0180] According to some alternative embodiments of this application, in combination with Figure 16 The angle γ between the central axis of the beam emitted by the optical device 250 and the surface to be cleaned satisfies the relationship: 2° ≤ γ ≤ 10°. Specifically, a smaller angle between the central axis of the beam emitted by the optical device 250 and the surface to be cleaned allows the shadow cast by the optical device 250 on the dirt on the surface to be cleaned to be projected longer, creating a clear contrast with the relatively brightly illuminated dirt. This helps the user identify the dirt on the surface to be cleaned, increases the likelihood that the floor brush 200 will capture the dirt when moving back and forth on the surface, reduces the time spent cleaning the surface, and thus reduces power consumption. The angle γ between the central axis of the beam emitted by the optical device 250 and the surface to be cleaned is 2°, 6°, and 10°, and is not limited to these.

[0181] According to some alternative embodiments of this application, in combination with Figure 16 The distance H between the center of the light-emitting element 2501 and the surface to be cleaned in the vertical direction satisfies the relationship: 2mm ≤ H ≤ 9.8mm. Specifically, the distance between the center of the light-emitting element 2501 and the surface to be cleaned is smaller in the vertical direction. This allows the light emitted by the light-emitting element 2501 to be closer to the dirt on the surface to be cleaned, and also allows the illumination angle of the optical device 250 to be shallower. This makes it easier for the user to identify the dirt on the surface to be cleaned, increases the likelihood that the dirt will be captured by the floor brush 200 when it moves back and forth on the surface to be cleaned, reduces the time spent cleaning the surface to be cleaned, and thus reduces power consumption.

[0182] According to some alternative embodiments of this application, in combination with Figure 13 and Figure 14The housing 210 includes a first sidewall 20a and a second sidewall 20b axially opposite to the roller brush 241. The roller brush 241 is rotatably disposed between the first sidewall 20a and the second sidewall 20b, and the optical device 250 is disposed near the first sidewall 20a. Specifically, the leading edge of the roller brush 241 is located between the first sidewall 20a and the second sidewall 20b. The first sidewall 20a and the second sidewall 20b, spaced apart along the axial direction of the roller brush 241 on the housing 210, define most of the area of ​​the surface to be cleaned where the dirt is irradiated by the optical device 250. When the roller brush 200 moves on the surface to be cleaned, the optical device 250 provides debris irradiation. This arrangement, based on a more obvious dirt visualization design, allows users to easily determine the movement path and the pushing frequency. For example, if there is too much dirt in front, the user can push slower to allow the dirt to be thoroughly cleaned. For stubborn dirt, the user can also clean repeatedly to ensure the cleaning effect. The first sidewall 20a can be either the right sidewall or the left sidewall.

[0183] Specifically, in combination Figure 14 and Figure 15 A suction chamber 208 is formed between the first sidewall 20a and the second sidewall 20b, and an optical device 250 is disposed between the first sidewall 20a and the suction chamber 208. When the vacuum cleaner is cleaning, the floor brush 200 includes a second air inlet 204. Dust is rolled up by the roller brush 241, and under negative pressure, the dust-laden airflow enters the suction chamber 208 from the second air inlet 204. Positioning the optical device 250 on one side of the floor brush 200 allows the optical device 250 to be accommodated within the floor brush 200 without excessively increasing the height of the floor brush 200, and also allows the optical device 250 to be positioned relatively close to the surface to be cleaned, thereby improving the rationality of the layout of the floor brush 200 structure.

[0184] According to some optional embodiments of this application, the light emitter 2501 is a laser diode or a light-emitting diode. Specifically, light-emitting diodes have the advantages of small size, light weight, and long service life. Using a light-emitting diode in the light emitter 2501 can improve the durability of its lighting function. Furthermore, laser diodes have the advantages of low power consumption, high light intensity, and good directionality. When the light emitter 2501 uses a laser diode to irradiate debris on the surface to be cleaned, power consumption can be reduced. Since it generates less heat during operation, no heat dissipation device, such as a fan or radiator, is needed to transfer heat from the laser diode to the surrounding atmosphere, thereby improving the luminous efficiency and economy of the light emitter 2501. For example, a blue light-emitting laser diode can be used. "Blue light" is light with a wavelength in the range of 360nm to 480nm. Compared with other colors of light of the same brightness, blue light has better focusing properties, providing a softer visual experience while maintaining brightness. Therefore, for the desired perceived intensity of illumination on the cleaning surface area in front of the floor brush 200, the use of a blue light-emitting laser can reduce power consumption, protect human eyesight, and provide a better visual experience.

[0185] Specifically, the light-emitting diode (LED) is either a blue LED or a green LED. "Blue light" refers to light with a wavelength in the range of 360nm to 480nm. Compared to other colors of light with the same brightness, blue light has better focusing properties, providing a softer visual experience while maintaining brightness. Therefore, for the desired perceived intensity of illumination on the surface to be cleaned in front of the floor brush 200, a blue-light-emitting LED can protect eyesight and provide a better visual experience.

[0186] Additionally, "green light" refers to light with wavelengths in the range of 495 to 570 nm. Compared to other colors of light with the same brightness, green light appears brighter to the human eye because the human eye contains a greater number of green photoreceptor cone cells than red or blue photoreceptor cells. For example, for a given brightness, a green laser is approximately eight times brighter than a red laser. Therefore, for the desired perceived intensity of illumination on the surface area to be cleaned in front of the floor brush 200, a green light-emitting diode can improve the user's visual ability to detect dirt.

[0187] According to some optional embodiments of this application, the beam assist device 2502 is a lens that receives emitted light and guides the beam to the surface to be cleaned. Specifically, the lens has excellent light-gathering ability, long range, and strong penetration. The beam assist device 2502 uses a lens to receive light emitted from the light emitter 2501 and guide the light to the surface to be cleaned where the floor brush 200 is placed. This can illuminate the dirt on the flat surface area to be cleaned more clearly and brightly, thereby increasing the likelihood that the dirt will be captured by the floor brush 200 when it moves back and forth on the surface to be cleaned, reducing the time spent cleaning the surface to be cleaned, and thus reducing power consumption.

[0188] The vacuum cleaner according to a second aspect of this application includes: a floor brush 200 for vacuum cleaners as described in the above embodiments. Specifically, the vacuum cleaner having the floor brush 200 can improve the user's visibility of dirt on the surface to be cleaned in environments with poor visibility, thereby achieving a better cleaning effect.

[0189] According to some optional embodiments of this application, the vacuum cleaner is a handheld vacuum cleaner. Specifically, handheld vacuum cleaners have a larger working range, are more convenient, and can be used in more cleaning environments.

[0190] According to some optional embodiments of this application, the vacuum cleaner also includes a body connected to the housing 210, and a battery (or power supply component 90) for power supply is disposed within the body. Thus, the vacuum cleaner can be a cordless vacuum cleaner. Specifically, the body and housing 210 of the vacuum cleaner are connected as a single unit, and the battery within the body provides power for the vacuum cleaner during cleaning and lighting operations, which improves the structural stability and design rationality of the vacuum cleaner.

[0191] According to some optional embodiments of this application, the vacuum cleaner also includes a body connected to the housing 210. A power unit and a controller are disposed within the body, and both the power unit and the light-emitting element 2501 are electrically connected to the controller. Specifically, the body and housing 210 of the vacuum cleaner are connected as a single unit. The body contains a power unit that drives the vacuum cleaner to perform cleaning operations and a controller that controls the vacuum cleaner to perform cleaning functions according to user needs. Both the power unit and the light-emitting element 2501 are connected to the controller via electrical signals, which improves the response speed and accuracy of the power unit and the light-emitting element 2501. The power unit can be a motor.

[0192] According to one specific embodiment of this application, when the power unit of the vacuum cleaner is turned on, the controller is arranged to activate the optical device 250. For example, the controller can provide a constant power to the optical device 250 so that the intensity of the light emitted from the optical device 250 remains unchanged when the motor is turned on. Alternatively, the controller can change the power supplied to the optical device 250 over time, so that the output light power of the optical device 250 changes over time.

[0193] For example, the power supplied by the controller to the optical device 250 can be varied gradually, or it can be gradually changed. Specifically, the power supplied to the optical device 250 gradually increases from the moment the power unit is turned on until the maximum supply power is reached.

[0194] For example, the maximum optical output power of the light-emitting element 2501 is 10mW in this embodiment. Within a few seconds of the motor being turned on, the power supplied to the optical device 250 can increase at a constant rate or vary over time. Specifically, when the motor is turned on, the power increase rate can be relatively low and gradually increase over time. Furthermore, in this embodiment, the light-emitting element 2501 is a laser diode. The controller is connected to the mating terminal 2101 of the ground brush 200 via one or more wires, and then connected to the optical device 250 via wires within the mating terminal 2101.

[0195] According to another specific embodiment of this application, the controller can delay supplying power to the optical device 250 for a period of time after the motor has been turned on. This relatively low or no power supply period for the optical device 250 can accommodate the time when the user positions the floor brush 200 on the work surface after turning on the motor, and thus accommodate the time when the optical device 250 does not project light onto the surface to be cleaned.

[0196] Optionally, when the motor is turned off, the controller is arranged to immediately stop supplying power to the optics 250. The controller may be arranged to adjust the power supply to the optics 250 based on changes in the state of the floor brush 200 or the vacuum cleaner when the motor is on. For example, the controller may pause, reduce, or otherwise adjust the power supply to the optics 250 based on the orientation of the floor brush 200 or the vacuum cleaner. One of the floor brush 200 or the vacuum cleaner may include a sensor that outputs a signal to the controller that varies according to its orientation, and the controller may be arranged to adjust the power supply to the optics 250 based on the output from the sensor.

[0197] Furthermore, if the floor brush 200 is lifted off the work surface, the controller can adjust the power supply to the optics 250. The floor brush 200 may include sensors, such as a steering wheel to detect whether the floor brush 200 has been lifted off the work surface, or a sensor to detect air pressure within the suction chamber 208, and the controller can be arranged to adjust the power supply to the optics 250 based on signals received from these sensors. When the vacuum cleaner's behavior changes, this change can indicate an interruption of the cleaning process, which can reduce the power consumption of the optics 250, for example, by repositioning the vacuum cleaner to another location in the home, thus saving battery power.

[0198] The controller is also configured to stop supplying power to the controller when the motor is turned off by the user or when the battery is depleted, which will also cause the light emitter 2501 to turn off, thereby achieving the effect of timely and effective shutdown of the light emitter 2501.

[0199] According to some embodiments of the present application, the floor brush 200 is easy to remove its auxiliary wheel 270 to avoid the auxiliary wheel 270 from getting stuck.

[0200] Combination Figures 17 to 21 According to one embodiment of this application, the floor brush 200 includes: a housing 210, an auxiliary wheel 270, and an operating component 280. The housing 210 is provided with a first mounting groove 261, the auxiliary wheel 270 is disposed in the first mounting groove 261, and the operating component 280 is movably connected to the auxiliary wheel 270. The operating component 280 has a first position and a second position. In the first position, the auxiliary wheel 270 is fixed to the housing 210 and is not detachable. In the second position, the auxiliary wheel 270 can be detached from the housing 210 and disassembled.

[0201] Specifically, the housing 210 is provided with a first mounting groove 261 for accommodating the auxiliary wheel 270. The auxiliary wheel 270 is used to assist the floor brush 200 in moving on the working surface. The operating component 280 and the auxiliary wheel 270 can be connected to move relative to each other in the axial direction. Moreover, the relative positions of the operating component 280 and the auxiliary wheel 270 can include a first position in which the auxiliary wheel 270 is in a fixed state and a second position in which the auxiliary wheel 270 is in a detached state. That is, when the operating component 280 is in the first position, the auxiliary wheel 270 and the floor brush 200 are in a fixed state. This allows the auxiliary wheel 270 to play an auxiliary guiding role for the floor brush 200, improving the cleaning convenience of the floor brush 200. When the user moves the operating component 280 to the second position, the auxiliary wheel 270 and the floor brush 200 are in a detachable state. This makes it easier for the user to remove hair around the auxiliary wheel 270 and effectively avoids the problem of the auxiliary wheel 270 being stuck by hair or other dirt.

[0202] Therefore, by designing the floor brush 200, users can flexibly switch the installation and removal states of the auxiliary wheel 270 according to their needs. This can prevent the auxiliary wheel 270 from getting stuck, improve the cleaning smoothness of the floor brush 200, and also improve the cleaning convenience of the floor brush 200 by utilizing the auxiliary guiding function of the auxiliary wheel 270.

[0203] According to some optional embodiments of this application, a second mounting groove 262 is provided on the housing 210, which is located on one side of the first mounting groove 261. A first shaft hole 2611 is provided between the second mounting groove 262 and the first mounting groove 261. The auxiliary wheel 270 is provided with a second shaft hole 271 opposite to the first shaft hole 2611. Specifically, the housing 210 is provided with a second mounting groove 262 for accommodating the operating component 280. A first shaft hole 2611 is provided between the first mounting groove 261 and the second mounting groove 262 along the transverse direction (i.e., left-right direction) of the floor brush 200. The auxiliary wheel 270 is provided with a second shaft hole 271 corresponding to the first shaft hole 2611. The first shaft hole 2611 and the second shaft hole 271 are coaxial, which can ensure the accuracy and convenience of assembly.

[0204] Furthermore, the operating component 280 includes an operating member 281 and a shaft 282. The operating member 281 is movably disposed in the second mounting groove 262, and the shaft 282 is disposed on the operating member 281. The shaft 282 passes through the first shaft hole 2611 and the second shaft hole 271 in sequence. The operating component 280 in the second mounting slot 262 is equipped with a shaft 282 extending laterally along the floor brush 200. When the operating component 280 moves laterally towards the side of the auxiliary wheel 270 within the second mounting slot 262, the shaft 282 can pass through the first shaft hole 2611 and the second shaft hole 271 in sequence, achieving the installation and positioning effect of the auxiliary wheel 270. When the operating component 280 moves laterally away from the auxiliary wheel 270 within the second mounting slot 262, the shaft 282 can pass through the second shaft hole 271 and the first shaft hole 2611 in sequence, achieving the disassembly effect of the auxiliary wheel 270. Compared with the traditional non-removable auxiliary wheel 270, the auxiliary wheel 270 can be flexibly and promptly disassembled and assembled according to user needs. It can remove hair around the auxiliary wheel 270 and effectively avoid the problem of the auxiliary wheel 270 being stuck by hair and other dirt, thereby improving the user's cleaning smoothness. Moreover, its structure is simple and convenient, thus improving the practicality of the floor brush 200.

[0205] According to some alternative embodiments of this application, in combination with Figures 19 to 21As shown, the housing 210 has a clearance space (not shown) on the side of the second mounting groove 262 away from the first mounting groove 261. The clearance space is connected to the second mounting groove 262, and a portion of the operating member 281 can selectively move to the clearance space. Specifically, the housing 210 has a clearance space in the lateral direction on the side of the second mounting groove 262 away from the first mounting groove 261. A portion of the operating member 281 can selectively move laterally to the clearance space under the action of external force. This allows the shaft 282 on the operating member 281 to have a space for lateral movement, which facilitates the shaft 282 to selectively move laterally and pass through the first shaft hole 2611 and the second shaft hole 271 as needed, thereby completing the disassembly and assembly of the auxiliary wheel 270.

[0206] Specifically, in combination Figures 19 to 21 As shown, the floor brush 200 also includes an elastic reset member 290, which is disposed in the clearance space. One end of the elastic reset member 290 abuts against the side wall of the clearance space, and the other end of the elastic reset member 290 abuts against the operating member 281. One end of the elastic reset member 290 abuts against the fixed sidewall of the clearance space opposite to the auxiliary wheel 270, and the other end abuts against the operating member 281. The elastic reset member 290 can undergo elastic deformation to generate elastic force. When the user removes the auxiliary wheel 270, the user can push the operating member 281 towards the clearance space opposite to the auxiliary wheel 270. The user's external force overcomes the elastic force of the elastic reset member 290, and at this time, the elastic reset member 290 is compressed laterally towards the side opposite to the auxiliary wheel 270. When the user releases the external force, the elastic reset member 290 is subjected to an elastic force laterally towards the auxiliary wheel 270, and the elastic reset member 290 will drive the operating member 281 to move towards the auxiliary wheel 270. This can play a role in fixing and limiting the auxiliary wheel 270 in the installed state, thereby improving its design rationality and practicality.

[0207] Furthermore, combined Figures 19 to 21 The operating member 281 is provided with a receiving groove 283 that opens toward the elastic reset member 290, and a portion of the elastic reset member 290 is disposed in the receiving groove 283. The elastic reset member 290 is located between the operating member 281 and the end of the second mounting groove 262 facing away from the auxiliary wheel 270. The receiving groove 283, which opens on the side of the operating member 281 toward the elastic reset member 290, can accommodate a portion of the elastic reset member 290 along its axial direction. This saves lateral space in the second receiving groove 283 while allowing the elastic reset member 290 to have a certain free length and a certain range of deformation stroke, making it easier for the user to overcome elastic force and move the operating member 281, thereby improving its space utilization and practicality.

[0208] According to some optional embodiments of this application, a third shaft hole 2612 is provided on the side wall of the first mounting groove 261 away from the second mounting groove 262. The third shaft hole 2612 is disposed opposite to the second shaft hole 271, and the shaft body 282 is also disposed through the third shaft hole 2612. Specifically, a third shaft hole 2612 is provided in the first mounting groove 261 that accommodates the auxiliary wheel 270. The third shaft hole 2612 is provided on the side wall of the second mounting groove 262, which is laterally opposite to the second mounting groove 262, relative to the second shaft hole 271 between the first mounting groove 261 and the second mounting groove 262. The shaft body 282, the second shaft hole 271 and the third shaft hole 2612 are coaxial. In the normal installation state of the auxiliary wheel 270, the shaft body 282 is connected to the auxiliary wheel 270 side by the second shaft hole 271, the first shaft hole 2611 and the third shaft hole 2612 in sequence. The third shaft hole 2612 plays a limiting role in connecting and fixing the end of the shaft body 282 facing the auxiliary wheel 270 side. It can limit the axial and circumferential directions of the shaft body 282, thereby improving the positional stability of the shaft body 282 and ensuring the rotational stability of the auxiliary wheel 270.

[0209] Regarding the handling of hair, if hair is wrapped around the auxiliary wheel 270, it will be cleaned when the auxiliary wheel 270 is disassembled. If hair is wrapped around the shaft 282, that is, wrapped around the shaft 282 on both sides of the auxiliary wheel 270, there is a first side and a second side. The first side is located between the auxiliary wheel 270 and the third shaft hole 2612, and the second side is located between the auxiliary wheel 270 and the first shaft hole 2611. When the shaft 282 moves, when the end of the shaft 282 leaves the third shaft hole 2612 and leaves the first side, the hair will be released. As the shaft 282 continues to move, the hair on the second side will be released when the end of the shaft 282 enters the first shaft hole 2611. The released hair is located in the second mounting groove 262 and can be removed along with the disassembly of the auxiliary wheel 270. With this setting, the detachable auxiliary wheel 270 facilitates the removal of hair and avoids the auxiliary wheel 270 getting stuck.

[0210] According to some optional embodiments of this application, the end of the shaft 282 facing away from the operating member 281 is constructed as a tapered guide end 2821. Specifically, the end of the shaft 282 facing away from the operating member 281 along the axial direction is constructed as a tapered guide end 2821, that is, a guide end 2821 with decreasing cross-sectional area. This makes it easier for the guide end 2821 to pass through the second shaft hole 271 and the first shaft hole 2611, thereby improving the convenience for the user when installing and removing the auxiliary wheel 270.

[0211] According to some alternative embodiments of this application, in conjunction with 19 to Figure 21The operating component 281 is provided with a raised rib 284, which contacts the wall of the second mounting groove 262. Specifically, the operating component 281 is provided with a raised rib 284 that contacts the groove wall of the second mounting groove 262. The raised rib 284 can reduce the friction area between the groove wall of the second mounting groove 262 and the operating component 281 when the user pushes the operating component 281, thereby reducing the force required when installing or removing the auxiliary wheel 270, improving the convenience of installation and removal and the user experience.

[0212] Specifically, in combination Figure 19 and Figure 20 There are multiple ribs 284, which are distributed on the side and / or bottom surface of the operating member 281. By providing multiple ribs 284, the operating member 281 can be evenly contacted with the wall of the second mounting groove 262, which can improve the smoothness of the movement of the operating member 281 and reduce the contact area between the operating member 281 and the wall of the second mounting groove 262.

[0213] According to some alternative embodiments of this application, in combination with Figures 19 to 21 The operating component 281 is provided with a protruding operating head 285, which protrudes from the second mounting groove 262. Specifically, the operating component 281 is provided with a downwardly protruding operating head 285, which protrudes downward from the second mounting groove 262. When the user needs to remove or install the auxiliary wheel 270, the user faces the bottom surface of the floor brush 200 towards themselves, with the operating head 285 facing upward towards the user. The operating head 285, protruding from the second mounting groove 262, is easier for the user to touch with their fingers, and the vertically protruding operating head 285 is easier for the user to grasp. The user directly applies horizontal external force to the operating head 285 to drive the operating component 281 to move laterally to complete the removal and installation of the auxiliary wheel 270. This saves effort and effectively improves the convenience of installation and removal.

[0214] Specifically, the auxiliary wheel 270 protrudes from the first mounting groove 261 at a height of h1, and the operating head 285 protrudes from the second mounting groove 262 at a height of h2. h1 and h2 satisfy the relationship: h1 > h2. The height of the auxiliary wheel 270 protruding downwards from the first mounting groove 261 is greater than the height of the operating head 285 protruding downwards from the second mounting groove 262. This arrangement prevents the operating head 285 from interfering with the normal rolling of the auxiliary wheel 270 when it rolls on the working surface, thus improving the rationality and scientific design of the floor brush 200. For example, the auxiliary wheel 270 protrudes from the first mounting groove 261 at a height of 6mm, and the operating head 285 protrudes from the second mounting groove 262 at a height of 3mm.

[0215] According to some alternative embodiments of this application, in combination with Figure 19The first mounting groove 261 and the second mounting groove 262 are spaced apart laterally on the housing 210. The first mounting groove 261 is located on the side of the second mounting groove 262 near the longitudinally extending central axis of the housing 210, or the second mounting groove 262 is located on the side of the first mounting groove 261 near the longitudinally extending central axis of the housing 210. For example, the first mounting groove 261 and the second mounting groove 262 are spaced apart laterally on the housing 210. The first mounting groove 261 can be flexibly arranged on the side of the second mounting groove 262 near the longitudinally extending central axis of the housing 210 according to design requirements. That is, the operating component 281 moves towards the side wall of the floor brush 200, that is, the auxiliary wheel 270 is located on the inner side laterally, and the unlocking operating component 280 is located on the outer side laterally, thereby improving the rationality and flexibility of the spatial arrangement of the auxiliary wheel 270.

[0216] According to some alternative embodiments of this application, in combination with Figures 17 to 19 There are at least two auxiliary wheels 270 and at least two operating components 280. Each of the at least two auxiliary wheels 270 corresponds to one of the at least two operating components 280. The at least two auxiliary wheels 270 are symmetrically arranged about the central axis extending longitudinally from the housing 210. Specifically, the at least two auxiliary wheels 270 are symmetrically arranged on both sides of the housing 210 in the transverse direction, and each of the at least two auxiliary wheels 270 corresponds to one of the at least two operating components 280. Compared to a single auxiliary wheel 270, this increases the number of contact points for the floor brush 200 on the working surface, resulting in smoother movement of the floor brush 200 on the working surface and thus improving the practicality of the floor brush 200.

[0217] Specifically, in combination Figures 17 to 19 The floor brush 200 also includes a main wheel 242, which is mounted on the housing 210 and located longitudinally behind at least two auxiliary wheels 270. For example, the floor brush 200 has two auxiliary wheels 270 symmetrically distributed laterally, and the main wheel 242 on the housing 210 is located longitudinally behind the two auxiliary wheels 270. This allows the main wheel 242, the two auxiliary wheels 270, and the working surface to form a relatively stable three-point support, which enables the floor brush 200 to move more smoothly and stably on the working surface.

[0218] According to some alternative embodiments of this application, in combination with Figure 19The floor brush 200 also includes a roller brush 241 and a brush strip 2411, both of which are mounted on the housing 210. The brush strip 2411 is located between the roller brush 241 and the auxiliary wheel 270. Specifically, along the longitudinal direction of the roller brush 241, the roller brush 241, the brush strip 2411, and the auxiliary wheel 270 are arranged sequentially at intervals. The roller brush 241 performs an initial brushing and suction of dirt on the working surface, and the brush strip 2411 performs a second brushing and sweeping of dirt missed by the roller brush 241, ensuring the cleaning effect of the floor brush 200 and effectively reducing the amount of hair tangled on the auxiliary wheel 270 behind the brush strip 2411.

[0219] Specifically, the roller brush 241 is at least partially installed in the housing 210. The roller brush 241 is cylindrical and includes bristles for engaging with the cleaning work surface. The front end of the roller brush 241 is exposed. The floor brush 200 includes a second air inlet. Dust is rolled up by the action of the roller brush 241, and under the drive of negative pressure, the dust-laden airflow enters the floor brush 200 from the second air inlet.

[0220] The cleaning device according to the second aspect of this application includes the floor brush 200 of the above embodiment. With this configuration, the cleaning device having the floor brush 200 can easily detach and assemble the auxiliary wheel 270 according to user needs, thereby effectively preventing the auxiliary wheel 270 from getting stuck and improving the user's cleaning smoothness.
