[0002] Vacuum cleaners, floor scrubbers and other cleaning equipment are widely used for environmental cleaning in various indoor and outdoor scenarios. Different cleaning equipment can perform various functions such as vacuuming and mopping, thereby maintaining a clean and tidy living and working environment.
[0003] In related technologies, cleaning equipment typically uses a floor brush device to clean the surface to be cleaned. The floor brush device cleans the surface by means of vacuuming, scraping, rinsing, etc. During the cleaning process, the floor brush device moves on the surface to be cleaned by rollers to clean different positions of the surface.
[0004] However, hair can easily get tangled in the rollers during movement, affecting the normal movement of the floor brush device. Utility Model Content
[0005] This application provides a floor brush device and cleaning equipment to solve the technical problem that hair easily gets tangled in the rollers during movement, affecting the normal movement of the floor brush device.
[0006] In a first aspect, this application provides a floor brush device, which includes a device body and a first roller. The device body has a floor brush duct, a first cavity and a second cavity. The floor brush duct has an air inlet. The first cavity is connected to the air inlet and is open towards the lower part of the device body. The second cavity is adjacent to and connected to the first cavity. The first roller is disposed in the first cavity.
[0007] When the floor brush device provided in this application is started, the air inlet will generate negative pressure suction, so that the garbage and debris on the surface to be cleaned in front of the first chamber can be sucked in. Since the second chamber and the first chamber are connected, the hair that enters the second chamber will also be sucked into the first chamber, thereby avoiding the hair from getting tangled in the first roller and affecting the normal movement of the floor brush device.
[0008] As an alternative implementation, the second cavity is located in front of the first cavity along the cleaning direction of the floor brush device.
[0009] This configuration, with the first roller located in the second cavity closer to the front of the floor brush device, improves the stability of the floor brush device's movement.
[0010] As an optional implementation, the lower edge of the front wall of the first cavity has a connecting notch that connects the first cavity and the second cavity.
[0011] With this design, hair and other debris in the second chamber can be sucked into the first chamber through the connecting opening, preventing hair from getting tangled in the rollers.
[0012] As an optional implementation, the first cavity extends along the width direction of the device body; the length of the first cavity matches the width of the device body; wherein the width direction of the device body is perpendicular to the cleaning direction of the floor brush device.
[0013] This configuration ensures that the cleaning range of the first cavity completely covers the entire width of the device body, guaranteeing thorough cleaning.
[0014] As an optional implementation, the length of the second cavity is less than the length of the first cavity along the width direction of the device body.
[0015] This setup reduces interference from the first roller on the cleaning coverage area, improving cleaning efficiency.
[0016] As an optional implementation, there are at least two second cavities, which are respectively located near both ends of the device body in the width direction.
[0017] This configuration ensures that there are at least two first rollers at both ends near the width of the device body, thereby improving the stability of the floor brush device's movement.
[0018] As an optional implementation, the first roller is rotatably disposed in the second cavity, and a portion of the structure of the first roller protrudes from the bottom of the second cavity to contact the surface to be cleaned.
[0019] With this configuration, the first roller can support the main body of the device, improving the stability of the floor brush device's movement.
[0020] As an optional implementation, the first cavity has airflow inlets at both ends along its length, and the air inlets are connected to the middle position along the length of the first cavity. The airflow entering the first cavity from the airflow inlets flows along the length of the first cavity to the air inlets. The second cavity is connected to the first cavity at a position on the airflow path within the first cavity.
[0021] This design ensures that hair and other debris in the second chamber are drawn into the first chamber and then carried by the airflow into the suction port, improving cleaning efficiency.
[0022] As an optional implementation, the main body of the device includes a housing and a cleaning component. The housing is arranged to form a floor brush air duct. The cleaning component includes a cleaning body connected to the housing. The cleaning body is configured to form a first cavity. The top wall of the cleaning body is provided with a suction port that communicates with the air inlet. The suction port communicates with the air inlet and the first cavity.
[0023] This design reduces structural complexity and increases structural compactness.
[0024] As an optional implementation, the cleaning assembly further includes a first scraping assembly, a second scraping assembly, and a first water spray module; both the first and second scraping assemblies are connected to the cleaning body and are located behind the first cavity in the cleaning direction of the floor brush device, and are distributed at intervals in front and behind, with the first and second scraping assemblies surrounding each other to form a third cavity, and the suction port is connected to the third cavity and the air inlet; the first water spray module is disposed on the cleaning body and is configured to spray cleaning water onto the surface to be cleaned corresponding to the third cavity.
[0025] With this configuration, the floor brush device can rinse the surface to be cleaned through the first water spray module and scrape the surface to be cleaned through the scraping component, thereby improving the cleaning effect.
[0026] As an optional implementation, the floor brush device also includes a second roller, which is located on the rear side of the main body of the device along the cleaning direction of the floor brush device.
[0027] With this configuration, the second roller and the first roller are located at the rear and front sides of the main body of the device, respectively, which can provide stable support for the main body of the device and improve the movement stability of the floor brush device.
[0028] Secondly, this application provides a cleaning device, which includes a main body and the aforementioned floor brush device.
[0029] The floor brush device provided in this application is used in cleaning equipment. The rollers installed at the bottom of the floor brush device can prevent tangling and ensure that the cleaning equipment can move normally and clean the surface to be cleaned during cleaning.
[0030] This application provides a floor brush device and cleaning equipment. The floor brush device includes a main body and a first roller. The main body has a floor brush air duct, a first cavity, and a second cavity. The floor brush air duct has an air inlet. The first cavity is connected to the air inlet and is open towards the bottom of the main body. The second cavity is adjacent to and connected to the first cavity, and the first roller is disposed in the first cavity. The floor brush device provided by this application, by opening the first cavity and the second cavity, allows hair entering the second cavity to be sucked into the first cavity, thereby preventing the first roller from being entangled by hair and affecting the normal movement of the floor brush device.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0045] Vacuum cleaners, floor scrubbers and other cleaning equipment are widely used for environmental cleaning in various indoor and outdoor scenarios. Different cleaning equipment can perform various functions such as vacuuming and mopping, thereby maintaining a clean and tidy living and working environment.
[0046] In related technologies, cleaning equipment typically uses a floor brush device to clean the surface to be cleaned. The floor brush device cleans the part of the surface to be cleaned by means of vacuuming, scraping, rinsing, etc. During the cleaning process, the floor brush device moves on the surface to be cleaned by rollers to clean different positions of the surface to be cleaned.
[0047] However, the cleaning components of a typical floor brush device are located between the front and rear rollers. When the floor brush device moves forward, the front roller will come into contact with the hair first, causing the hair to get tangled on the front roller and affecting the normal movement of the floor brush device.
[0048] To solve the above-mentioned technical problems, this application provides a floor brush device. The floor brush device is provided with a suction port that can suck up garbage and debris from the first cavity. At the same time, the roller on the front side of the floor brush device is rotatably disposed in the second cavity. The first cavity and the second cavity are adjacent to each other. By opening up the first cavity and the second cavity, hair from the second cavity can be sucked into the second cavity, thereby preventing hair from getting tangled in the roller and affecting the movement of the floor brush device.
[0049] The following section provides examples illustrating the application scenarios of the floor brush device and cleaning equipment provided in the embodiments of this application.
[0050] The floor brush device provided in this application embodiment is applied in cleaning equipment and is a cleaning structure in the cleaning equipment that comes into contact with the surface to be cleaned. The product type of the cleaning equipment in this application embodiment may include, but is not limited to, vacuum cleaners, floor scrubbers, and robotic vacuum cleaners. Depending on the different product types, the cleaning equipment provided in this application embodiment can be used to clean various types of floors and other surfaces. This application embodiment does not make any specific limitations in this regard.
[0051] Figure 1 This is a schematic diagram of the structure of the floor brush device provided in the embodiments of this application; Figure 2 This is a bottom schematic diagram of the floor brush device provided in an embodiment of this application.
[0052] See Figure 1 and Figure 2 As shown, this application embodiment provides a floor brush device 10, which can move on a surface to be cleaned and clean the surface. The floor brush device 10 includes a device body 100 and a first roller 200. The device body 100 has a floor brush air duct, a first cavity 110 and a second cavity 120. The floor brush air duct has an air inlet. The first cavity 110 is connected to the air inlet and is open towards the lower part of the device body 100. The second cavity 120 is adjacent to and connected to the first cavity 110. The first roller 200 is disposed in the first cavity 110.
[0053] It should be noted that the main body 100 of the device may be equipped with a suction unit. When the floor brush device 10 is started, the suction unit starts to work. The suction unit is connected to the air inlet through the floor brush air duct, so that the air inlet generates negative pressure. The air inlet is connected to the first cavity 110, and the first cavity 110 also generates negative pressure. The garbage and debris on the surface to be cleaned in the first cavity 110 will enter the air inlet along the first cavity 110 under the action of negative pressure suction, and enter the collection device through the floor brush air duct.
[0054] Understandably, since the second cavity 120 is connected to the first cavity 110, when the suction unit is activated, the first cavity 110 generates negative pressure, and a pressure difference is generated between the first cavity 110 and the second cavity 120, thereby generating airflow from the second cavity 120 to the first cavity 110. When hair enters the second cavity 120, the hair will be swept up by the airflow and carried into the first cavity 110, and finally collected in the collection device. By connecting the first cavity 110 and the second cavity 120, a large amount of hair can be effectively prevented from getting tangled in the first roller 200 located in the second cavity 120, ensuring the normal movement of the floor brush device 10.
[0055] Reference Figure 1 and Figure 2The direction of movement of the floor brush device 10 during cleaning is defined as the X direction, and the width direction of the floor brush device 10 is defined as the Y direction, which is perpendicular to the x-axis. Figure 1 The orientation of the paper is Y-axis, which is perpendicular to X-axis.
[0056] As one possible implementation, along the cleaning direction of the floor brush device 10, the second cavity 120 is located in front of the first cavity 110. Since the first roller 200 is disposed in the second cavity 120, the second cavity 120 needs to be as close as possible to the front of the device body 100, so that the first roller 200 can be closer to the front of the device body 100, ensuring that the first roller 200 can provide stable support for the floor brush device 10 and ensuring the movement stability of the floor brush device 10. At the same time, it is necessary to ensure that the first cavity 110 and the second cavity 120 are adjacent, so as to connect the first cavity 110 and the second cavity 120.
[0057] It should be noted that when the floor brush device 10 moves along the cleaning direction, since the first roller 200 is located in front of the first cavity 110, the first roller 200 will first come into contact with hair and other debris. When the hair gradually accumulates and wraps around the first roller 200, it will affect the cleaning work of the floor brush device 10. By opening the first cavity 110 and the second cavity 120, the hair can be allowed to enter the first cavity 110 with the airflow, thus preventing the first roller 200 from being wrapped.
[0058] As one possible implementation, the lower edge of the front cavity wall of the first cavity 110 has a connecting notch 111, which connects the first cavity 110 and the second cavity 120.
[0059] For example, the second cavity 120 has a semi-open cavity shell that fits against the front cavity wall of the first cavity 110 and together with the front cavity of the first cavity 110 forms the second cavity 120. A ventilation opening is provided at the fit between the shell of the second cavity 120 and the front cavity wall of the first cavity 110. The ventilation opening is located at the lower edge of the front cavity wall of the first cavity 110. When air enters through the air inlet, the airflow can flow from both sides of the first roller 200 axially and from the top of the first roller 200, and flow into the first cavity 110 through the ventilation opening.
[0060] As one possible implementation, the first cavity 110 extends along the width direction of the device body 100; the length dimension of the first cavity 110 matches the width dimension of the device body 100; wherein, the width direction of the device body 100 is perpendicular to the cleaning direction of the floor brush device 10.
[0061] Understandably, the first cavity 110 faces the surface to be cleaned. Under the action of negative pressure suction, the debris on the surface to be cleaned can be sucked into the air inlet. As the floor brush device 10 moves continuously, the debris on the moving path can be sucked in. Since the length of the first cavity 110 matches the width of the device body 100, the cleaning range of the first cavity 110 can cover the entire moving path.
[0062] As one possible implementation, along the width direction of the device body 100, the length of the second cavity 120 is less than the length of the first cavity 110.
[0063] For example, the length of the second cavity 120 can be matched with the width of the ventilation opening and slightly larger than the width of the first roller 200, so that the length of the second cavity 120 is minimized as much as possible without affecting the rotation of the first roller 200, so as to avoid sticking and accumulating garbage and debris.
[0064] As one possible implementation, there are at least two second cavities 120, with each of the at least two second cavities 120 being disposed near both ends of the device body 100 in the width direction.
[0065] For example, there are two first rollers 200, which are respectively disposed near both ends of the device body 100 in the width direction. Correspondingly, there are also two second cavities 120, with the two first rollers 200 respectively disposed in the two second cavities 120. Both second cavities 120 are connected to the first cavity 110 through ventilation openings. The two first rollers 200 are located at the top corners of the front side of the device body 100, which can form a stable support.
[0066] As one possible implementation, the first roller 200 is rotatably disposed in the second cavity 120, and a portion of the structure of the first roller 200 protrudes from the bottom of the second cavity 120 to contact the surface to be cleaned.
[0067] For example, shaft holes can be opened on both sides of the second cavity 120, and sealed bearings can be built in. The first roller 200 passes through the bearing through the shaft. The first roller 200 can be axially limited by the snap ring to prevent the first roller 200 from rubbing against the side wall of the second cavity 120. A silicone sealing ring is added at the roller shaft hole to prevent hair and small debris from entering.
[0068] The first roller 200 protrudes from below the second cavity 120 and contacts the surface to be cleaned. The first roller 200 supports the main body 100 of the device through a rotating shaft and bearing. Its protruding part contacts the ground to form a stable fulcrum, which can share the weight of the main body while ensuring the flexibility of movement. The protrusion height of the first roller 200 can be controlled by adjusting the installation height of the rotating shaft or the diameter of the roller. It is necessary to ensure the contact friction while avoiding excessive protrusion that would hinder the cleaning component 140 from touching the ground.
[0069] As one possible implementation, the first cavity 110 has airflow inlets 112 at both ends along its length. The air inlets are connected to the middle position along the length of the first cavity 110. The airflow entering the first cavity 110 from the airflow inlets 112 flows along the length of the first cavity 110 to the air inlets. The second cavity 120 is connected to the first cavity 110 at a position on the airflow path within the first cavity 110.
[0070] It should be noted that the airflow inlet 112 connects the first cavity 110 with the external environment, and the two ventilation gaps are located between the two airflow inlets 112. The connection between the air inlet and the first cavity 110 is located between the two ventilation gaps. When the suction unit is working, the air inlet generates negative pressure. On the one hand, the airflow enters the first cavity 110 from the ventilation gaps, carrying hair and debris. On the other hand, it enters the first cavity 110 from the airflow inlet 112. The airflow entering the first cavity 110 from the airflow inlet 112 flows along the length of the first cavity 110 to the air inlet. During the flow, the hair and debris entering from the ventilation gaps can be carried into the air inlet.
[0071] As one possible implementation, the main body 100 of the device includes a housing and a cleaning assembly 140. The housing is arranged to form a floor brush air duct. The cleaning assembly 140 includes a cleaning body 141, which is connected to the housing. The cleaning body 141 is configured to form a first cavity 110. The top wall of the cleaning body 141 is provided with a suction port 150 that communicates with the air inlet. The suction port 150 communicates with the air inlet and the first cavity 110.
[0072] It is understandable that the garbage and debris on the surface to be cleaned, as well as the garbage and debris entering the first cavity 110 through the ventilation opening, can enter the suction port 150 along the cavity wall of the first cavity 110 under the suction force of the suction port 150, and then enter the air inlet through the suction port 150, and enter the collection device through the floor brush air duct.
[0073] As one possible implementation, the cleaning component 140 also includes a first scraping component 142, a second scraping component 143, and a first water spray module 144; the first scraping component 142 and the second scraping component 143 are both connected to the cleaning body 141 and are located behind the first cavity 110 in the cleaning direction of the floor brush device 10, and are distributed at intervals in front and behind, forming a third cavity 130 between the first scraping component 142 and the second scraping component 143, and the suction port 150 connects the third cavity 130 and the air inlet; the first water spray module 144 is disposed on the cleaning body 141 and is configured to spray cleaning water onto the surface to be cleaned corresponding to the third cavity 130.
[0074] Understandably, when the floor brush device 10 cleans the surface to be cleaned along the cleaning direction, the suction port 150 of the first chamber 110 can first perform a coarse suction on the surface to be cleaned, sucking in large particles of debris and stains. As the floor brush device 10 moves, the first water spray module 144 can rinse the surface to be cleaned in the third chamber 130 through the water spray hole 145, and cooperate with the first scraping component 142 and the second scraping component 143 to scrape away stubborn stains, stuck debris and cleaning wastewater from the surface to be cleaned, thereby achieving effective cleaning of the surface to be cleaned.
[0075] In some embodiments, the suction port 150 may include a first suction port 151, a second suction port 152, and a third suction port 153. The first suction port 151 is opposite to and communicates with the first cavity 110. The second suction port 152 is located between the first scraping assembly 142 and the first water spray module 144. The third suction port 153 is located between the second scraping assembly 143 and the first water spray module 144. The first suction port 151 and the second suction port 152 are separated by the first scraping assembly 142. When the floor brush device 10 is cleaning, the first suction port 151 can suck up the debris and dirt on the surface to be cleaned opposite the first cavity 110. The second suction port 152 and the third suction port 153 can suck up the debris and dirt on the surface to be cleaned opposite the third cavity 130, as well as cleaning water.
[0076] As one possible implementation, the floor brush device 10 also includes a second roller 300, which is located on the rear side of the device body 100 along the cleaning direction of the floor brush device 10.
[0077] Understandably, since the second roller 300 is located at the rear of the device body 100, its movement path has been cleaned by the cleaning component 140, eliminating the need to consider hair entanglement. The first roller 200 and the second roller 300 together provide stable support for the device body 100. The diameters of the first roller 200 and the second roller 300 can be determined according to the usage scenario. For example, the first roller 200 is a small-diameter roller, and the second roller 300 is a large-diameter roller. The first roller 200 is located in the second cavity 120, and the second roller 300 is located on the outside of the device body 100, with the entire body exposed to the external environment.
[0078] It should be noted that there can be two second rollers 300. Increasing the diameter of the second rollers 300 increases the contact area between them and the surface to be cleaned, thereby improving the stability of the floor brush device 10. The first roller 200 can be a swivel wheel, supporting 360° rotation, making it easier for the floor brush device 10 to turn. The cleaning component 140 is located between the second rollers 300 and the first rollers 200, and the center of gravity of the floor brush device 10 is closer to the second rollers 300, making the floor brush device 10 more stable when turning.
[0079] It should be noted that the floor brush device 10 provided in this application is applied to cleaning equipment, which includes a main body and the aforementioned floor brush device 10, with the main body connected to the top of the floor brush device 10. The rollers of the floor brush device 10 provided in this application are tangle-free, ensuring that the cleaning equipment can move normally and clean the surface to be cleaned during cleaning.
[0080] This application provides a floor brush device 10 and a cleaning device. The floor brush device 10 includes a device body 100 and a first roller 200. The device body 100 has a floor brush air duct, a first cavity 110 and a second cavity 120. The floor brush air duct has an air inlet. The first cavity 110 is connected to the air inlet and is open downwards towards the device body 100. The second cavity 120 is adjacent to and connected to the first cavity 110. The first roller 200 is disposed in the first cavity 110. The floor brush device 10 provided by this application, by opening the first cavity 110 and the second cavity 120, allows hair entering the second cavity 120 to be sucked into the first cavity 110, thereby preventing the first roller 200 from being entangled by hair and affecting the normal movement of the floor brush device 10.
[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
