Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a floor brush assembly and cleaning equipment. Background Technology

[0002] With the continuous development of cleaning equipment technology, the application of cleaning equipment such as floor scrubbers and washer-mop combos is becoming increasingly widespread. These cleaning devices offer diverse functions and are used in increasingly diverse scenarios. However, current cleaning equipment is basically limited to cleaning surfaces such as floors and carpets, neglecting the cleaning of side surfaces such as baseboards. Cleaning baseboards is often considered a tedious chore, but keeping them free from dust, hair, and splatter can greatly improve the appearance of any room. Utility Model Content

[0003] In view of the above problems, this application provides a floor brush assembly and a cleaning device.

[0004] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0005] The first aspect of this application provides a floor brush assembly and a cleaning device. The floor brush assembly includes a floor brush body and a cleaning component. The cleaning component is connected to the floor brush body and contacts the surface to be cleaned to clean the surface.

[0006] The bottom of the floor brush body is provided with a main suction port, which is used to suck up dirt from the surface to be cleaned;

[0007] The main body of the floor brush is provided with a side suction port and bristles on its side. The bristles are located at the edge of the side suction port and are used to clean the baseboard area. The height of the side suction port is higher than that of the main suction port. The side suction port is used to at least suck up the debris in the baseboard area.

[0008] During the cleaning process, as the floor brush assembly moves along the floor, the cleaning components rub against and clean the surface, while debris is sucked away through the main suction port. Existing floor brush assemblies, although some have side brushes, only clean along the edges of the surface in the horizontal direction, failing to address vertical cleaning. The baseboard area is prone to dirt accumulation, but existing technologies lack effective solutions for cleaning this area. Therefore, this application designs a floor brush assembly capable of effectively cleaning the baseboard area. Specifically, when the floor brush assembly moves near the baseboard, the user can adjust the side of the assembly to be flush against or close to the baseboard and move it along the baseboard's extension direction. The side suction port can at least suck away dust and other debris accumulated on the top of the baseboard.

[0009] As the user pushes and pulls the floor brush assembly, the brush body moves the bristles back and forth along the baseboard, allowing the bristles to brush up debris by rubbing against the baseboard area. This separates the debris from the baseboard surface, making it easier for the side suction port to remove it. The bristles also reduce suction loss at the side suction port, ensuring sufficient suction power. The bristles, combined with the negative pressure suction of the side suction port, improve cleaning effectiveness.

[0010] During the cleaning of the baseboard area, the cleaning component remains in contact with the floor. This means that the brush assembly doesn't need to be lifted while cleaning the baseboards; the user can simply continue the pushing and pulling motion to clean the floor, making it convenient and effortless. Even as the side suction port cleans the baseboard area, the main suction port is also cleaning the floor, allowing the brush assembly to clean the baseboard area while cleaning the floor, improving cleaning efficiency and experience. Optionally, the brush body also includes a main air duct and side air ducts, with the main suction port serving as the inlet to the main air duct and the side suction port as the inlet to the side air duct. The brush assembly also includes a switch that can toggle between at least a main suction position and a side suction position. When the switch is in the main suction position, the side air duct is closed; when the switch is in the side suction position, at least the side air duct is open, allowing the side suction port to remove debris from the baseboard area.

[0011] Debris from the floor enters the main air duct through the main suction inlet, while debris from the baseboard area enters the side air duct through the side suction inlet. Unlike the floor, the baseboard area has less debris caused by human activity and is mostly accumulated dust, requiring less frequent cleaning. Using a switch, when cleaning the baseboard area is needed, adjust the switch to the side suction position to open the side air duct and clean the area. When cleaning the baseboard area is not needed, adjust the switch to the main suction position, opening the main air duct for normal floor cleaning, saving power.

[0012] For example, the airflow from the main duct and the side ducts originates from the same main motor. When the switch is in the main suction position, because the side ducts are closed, the airflow can be concentrated more in the main duct, effectively ensuring the negative pressure suction at the main suction port, resulting in better floor cleaning. When the switch is in the side suction position, the side duct can be activated independently while the main duct is closed. Alternatively, both the side ducts and the main duct can be activated simultaneously.

[0013] Optionally, the main air duct is provided with an air inlet. When the switch is in the main suction position, the switch closes the air inlet to shut down the side air duct. When the switch is in the side suction position, the switch opens the air inlet, and the main air duct and the side air duct are connected.

[0014] Waste from the skirting board area enters the side duct through the side suction inlet, then passes through the vent into the main duct, and finally flows into the wastewater tank. In other words, waste sucked up by both the side and main suction inlets can be sent to the wastewater tank via the main duct. In this structure, the vent is equivalent to an opening on the side wall of the main duct. The side and main ducts share a portion of the side wall (this shared side wall has the vent), which not only simplifies the side duct structure and improves the utilization of space within the brush unit, but also requires almost no modification to the original main duct structure and routing, thus reducing design, development, and production costs.

[0015] By setting the air vent, when the switch is in the side suction position, the main air duct is not closed, and both the side air duct and the main air duct are open at the same time.

[0016] Optionally, the floor brush assembly further includes a seal, which, when the switch is in the main suction position, is in contact with the inner wall of the air vent and the switch to seal the air vent.

[0017] When the switch is in the main suction position, thanks to the sealing effect of the sealant, almost no airflow will enter the main air duct through the gap between the switch and the inner wall of the air outlet, effectively ensuring the negative pressure in the main air duct and reducing unnecessary suction loss.

[0018] Optionally, the floor brush assembly is further provided with a swing arm, a first position switch and a second position switch, the swing arm being connected to the switching switch and moving synchronously with the switching switch;

[0019] During its movement, the swing arm can contact or approach the first position switch and the second position switch respectively. When the swing arm contacts or approaches the first position switch, the first position switch generates a first signal, which is used to indicate that the switching switch is in the main suction position. When the swing arm contacts or approaches the second position switch, the second position switch generates a second signal, which is used to indicate that the switching switch is in the side suction position.

[0020] The first and second position switches can automatically identify the position of the changeover switch, facilitating intelligent control of the opening or closing of the side air duct. By setting a swing arm that is linked to the changeover switch, the first and second position switches do not need to be coordinated with the changeover switch, allowing for more flexible position settings.

[0021] Optionally, the floor brush assembly further includes a drive assembly disposed on the floor brush body, the drive assembly being connected to the swing arm and / or the switching switch to drive the swing arm and the switching switch to move.

[0022] Optionally, the drive assembly includes a switching motor, and the floor brush assembly further includes a controller disposed on the floor brush body, the controller being electrically connected to the first position switch, the second position switch and the switching motor respectively;

[0023] The controller can control the switching motor to stop rotating based on the first signal or the second signal.

[0024] Optionally, the side air duct includes a guide section and an air inlet section, the air inlet section being connected to the guide section and the side suction port respectively, and the inner diameter of the air inlet section increasing from the guide section towards the side suction port.

[0025] After the waste enters the air intake section through the side suction inlet, it then enters the air guide section. Because the inner diameter of the air intake section increases from the air guide section towards the side suction inlet, the side suction inlet can have a larger cross-sectional area, which can improve the cleaning efficiency of the baseboard area.

[0026] Optionally, the bristles are arranged in an outward-expanding shape around the side suction port.

[0027] The outward-expanding bristles can also expand the negative pressure, increasing the effective adsorption range at the side suction port.

[0028] A second aspect of this application provides a cleaning device, which includes a floor brush assembly, a body, a main motor, and a handle as described in the first aspect embodiment. The body is connected to the floor brush assembly and the handle, and the main motor is located on the body and is capable of generating at least a suction flow through the main suction port.

[0049] See Figure 1 The cleaning equipment includes a floor brush assembly 100 and a main motor 230. The floor brush assembly 100 includes a floor brush body 110 and a cleaning component 140. The floor brush body 110 has a main suction port 121. Figure 3 ).

[0050] During the cleaning process, the floor brush assembly 100 moves along the surface to be cleaned, and the cleaning component 140 generates friction with the surface, effectively removing dirt from the surface. Under the negative pressure suction generated by the main motor 230, the dirt removed by the cleaning component 140 is drawn away through the main suction port 121, thus completing the cleaning of the surface.

[0051] Cleaning components 140 include, but are not limited to, roller brushes, track structures, and cleaning discs.

[0052] Alternatively, cleaning equipment includes handheld cleaning devices such as floor scrubbers, electric mops, vacuum cleaners, and mop-washer combos.

[0053] See Figure 1 For handheld cleaning devices, the cleaning device may also include a body 200 and a handle 220, with the body 200 connected to the floor brush assembly 100 and the handle 220 respectively. During the cleaning process, the user can hold the device on the handle 220 and swing the body 200 through the handle 220 to push the floor brush body 110 forward (the forward movement direction can also be called the travel direction) or pull it backward, so that the floor brush assembly 100 moves back and forth along the surface to be cleaned. During the movement, the floor brush body 110 causes the cleaning component 140 to come into frictional contact with the surface to be cleaned.

[0054] The cleaning equipment may also include a clean water tank and a wastewater tank 210. The clean water tank stores cleaning liquid and is used to wet the cleaning component 140, allowing it to soak the stains on the surface to be cleaned during the cleaning process, reducing the adhesion of the stains and improving the cleaning effect. The main motor 230 draws the waste from the surface to be cleaned through the main suction port 121 into the wastewater tank 210, which is used to temporarily store the waste generated during the cleaning process. The waste is generally a mixture of solids and liquids.

[0055] Currently, the primary cleaning target of the floor brush component 100 is the surface located at the bottom of the component, such as a roughly horizontal surface like a floor or carpet. For ease of description, the following description uses a floor as an example. Surfaces located to the side of the floor brush component 100 (such as the baseboard area) are often overlooked. A baseboard typically refers to a long strip of decorative material installed at the junction of the wall and the floor. The baseboard area includes, but is not limited to, the baseboard itself (including the side of the baseboard roughly perpendicular to the floor and the top surface of the baseboard roughly parallel to the floor), and may also include the wall above and near the baseboard, or vertical or steeply angled surfaces such as furniture facades, door frames, and walls without baseboards. Because the baseboard is located above the floor, outside the cleaning path of the floor brush component 100, it cannot be cleaned by the component. Common cleaning methods include manually wiping with a cloth or using a vacuum cleaner with a narrow crevice tool to remove debris from the baseboard area. These methods require a lot of manual intervention and are time-consuming and laborious. To facilitate cleaning of the baseboard area, improve the cleaning experience, and increase cleaning efficiency, the embodiments of this application provide the following technical solutions.

[0056] Example 1

[0057] An embodiment provides a floor brush assembly 100, see below. Figures 2 to 4The floor brush assembly 100 includes a floor brush body 110 and a cleaning component 140. The cleaning component 140 is connected to the floor brush body 110 and contacts the surface to be cleaned to clean the surface. The bottom of the floor brush body 110 is provided with a main suction port 121, which is used to suck up dirt from the surface to be cleaned. The side of the floor brush body 110 is provided with a side suction port 131 and bristles 138. The bristles 138 are located at the edge of the side suction port 131 and are used to clean the baseboard area. The height of the side suction port 131 is higher than the position of the main suction port 121. The side suction port 131 is used to at least suck up the debris in the baseboard area.

[0058] During the cleaning process as the floor brush assembly 100 moves along the floor, the cleaning component 140 rubs and cleans the floor, and debris on the floor is sucked away by the main suction port 121. When the floor brush assembly 100 moves near the baseboard, the user can adjust the side of the floor brush assembly 100 to be against or close to the baseboard and move it along the extension direction of the baseboard. The side suction port 131 can at least suck away dust and other debris accumulated on the top of the baseboard. When the user pushes and pulls the floor brush assembly 100, the floor brush body 110 drives the bristles 138 to move back and forth along the baseboard, allowing the bristles 138 to sweep away debris, separating it from the surface of the baseboard area, making it easier for the debris to be sucked away by the side suction port 131. The bristles 138 can also reduce the loss of suction at the side suction port 131, ensuring suction power. The bristles 138, together with the negative pressure suction of the side suction port 131, can improve the cleaning effect.

[0059] The bristles 138 can be arranged around the outer periphery of the side suction port 131. But it is not limited to this.

[0060] The bristles (138) can be stiff, such as those made of plastic. This makes them more effective at cleaning up trash and also more wear-resistant.

[0061] During the cleaning of the baseboard area, the cleaning component 140 remains in contact with the floor. This means that the user doesn't need to lift the floor brush assembly 100 while cleaning the baseboard area; they can simply continue the pushing and pulling motion to clean the floor, making it convenient and effortless. Furthermore, while the side suction port 131 is cleaning the baseboard area, the main suction port 121 is also cleaning the floor, allowing the floor brush assembly 100 to clean the baseboard area while simultaneously cleaning along the floor, improving cleaning efficiency and the overall cleaning experience.

[0062] See Figure 1 The side of the floor brush assembly 100 refers to the part that is approximately perpendicular to the direction of travel of the floor brush assembly 100 on the ground, that is, the side refers to the left or right side of the floor brush body 110. Figure 1 and Figure 2 Although the side suction port 131 is shown exemplarily on the right side of the brush body 110, in other implementations, the side suction port 131 may also be located on the left side of the brush body 110, or the brush body 110 may have side suction ports 131 on both the left and right sides.

[0063] The number of side suction ports 131 is at least one, and the number of side suction ports 131 can be [number missing]. Figure 2 The number of side suction ports 131 shown may be one, two, three or more, and is not intended to limit the embodiments of this application.

[0064] The side suction port 131 is roughly parallel to the direction of the skirting board.

[0065] The height of the side suction port 131 is roughly matched with the baseboard. Since the debris on the baseboard mainly accumulates at the top, the top of the baseboard needs to be within the airflow range towards the side suction port 131 to ensure cleaning effectiveness.

[0066] In some cases, the airflow range to the side suction port 131 is greater than the cross-sectional area of ​​the side suction port 131. The side suction port 131 can not only suck up the trash on the top of the baseboard, but also the side of the baseboard, and even the trash on the wall above the baseboard, although there is less trash in these two places.

[0067] The opening area of ​​the side suction port 131 is not necessarily continuous with the opening area of ​​the main suction port 121. For example, the opening area of ​​the side suction port 131 can be smaller than the opening area of ​​the main suction port 121, or it can be equal to or larger than the opening area of ​​the main suction port 121.

[0068] See Figures 3 to 5 In some optional embodiments, the floor brush body 110 further includes a main air duct 120 and a side air duct 130, with the main suction port 121 being the inlet of the main air duct 120 and the side suction port 131 being the inlet of the side air duct 130; see also Figure 4 , Figure 6 and Figure 7 The floor brush assembly 100 also includes a switch 133, which can switch between at least a main suction position and a side suction position. When the switch 133 is in the main suction position, the side air duct 130 is closed. When the switch 133 is in the side suction position, at least the side air duct 130 is open, so that the side suction port 131 can suck up the debris in the baseboard area.

[0069] Debris on the ground enters the main air duct 120 through the main suction inlet 121, while debris from the baseboard area enters the side air duct 130 through the side suction inlet 131. Unlike the ground, the baseboard area has less debris caused by human activity and is mostly accumulated dust, requiring less frequent cleaning. Using the switch 133, when cleaning the baseboard area is needed, the switch is adjusted to the side suction position, activating the side air duct 130 for cleaning. When cleaning the baseboard area is not needed, the switch is adjusted to the main suction position, activating the main air duct 120 for normal floor cleaning, saving power.

[0070] For example, the airflow from the main duct and the side duct originates from the same main motor. When the switch is in the main suction position, since the side duct 130 is closed, the airflow can be concentrated more on the main duct 120, effectively ensuring the negative pressure suction at the main suction port 121, resulting in better floor cleaning. When the switch 133 is in the side suction position, the side duct 130 can be turned on independently while the main duct 120 is closed. Alternatively, both the side duct 130 and the main duct 120 can be turned on simultaneously.

[0071] Optionally, the main air duct 120 and the side air duct 130 can be connected. Garbage on the ground enters the main air duct 120 through the main suction port 121, and then flows into the wastewater tank 210 from the main air duct 120. Because the main air duct 120 and the side air duct 130 can be connected, the negative pressure suction force generated by the same main motor 230 can be used to remove garbage from both the ground and the baseboard area. Furthermore, when the main air duct 120 and the side air duct 130 are connected, cleaning of both the ground and the baseboard area can be achieved simultaneously.

[0072] See Figure 4 In some optional embodiments, the main air duct 120 is provided with an air outlet 122. When the switch 133 is in the main suction position, the switch 133 closes the air outlet 122 to close the side air duct 130; when the switch 133 is in the side suction position, the switch 133 opens the air outlet 122, and the main air duct 120 and the side air duct 130 are connected.

[0073] Figure 3 and Figure 4 The diagram shows a cross-sectional view of the floor brush assembly 100 when the switch 133 is in the main suction position and the air vent 122 is closed. Debris from the baseboard area enters the side air duct 130 through the side suction port 131, then passes through the air vent 122 into the main air duct 120, and finally enters the wastewater tank 210 from the main air duct 120. In other words, debris sucked up by both the side suction port 131 and the main suction port 121 can be sent to the wastewater tank 210 via the main air duct 120. In this structure, the air vent 122 is equivalent to an opening on the side wall of the main air duct 120. The side air duct 130 and the main air duct 120 share a portion of their side wall, for example: see [link to relevant documentation]. Figure 4 A duct cover 132 can be installed, and a side duct 130 is formed between the duct cover 132 and the side wall of the main duct 120 where the air outlet 122 is located. In this way, not only is the structure of the side duct 130 simpler and the space utilization rate of the floor brush body 110 improved, but the original structure and direction of the main duct 120 of the floor brush body 110 also hardly need to be changed, which helps to reduce design, development and production costs.

[0074] By setting the air vent 122, when the switch 133 is in the side suction position, the main air duct 120 is not closed, and the side air duct 130 and the main air duct 120 are opened at the same time.

[0075] See Figure 4 In some optional embodiments, the floor brush assembly 100 further includes a seal 134. When the switch 133 is in the main suction position, the seal 134 is in contact with the inner wall of the air vent 122 and the switch 133 respectively to seal the air vent 122. When the switch 133 is in the main suction position, under the sealing effect of the seal 134, almost no airflow enters the main air duct 120 through the gap between the switch 133 and the inner wall of the air vent 122, effectively ensuring the negative pressure in the main air duct 120 and reducing unnecessary suction loss.

[0076] The seal 134 can be an annular shape with approximately the same shape and inner diameter as the air vent 122. The seal 134 can be installed on the inner wall of the air vent 122, covering the air vent 122 and tightly fitting against the seal 134 when the switch 133 moves towards the opening. Alternatively, the seal 134 can also be installed on the switch 133 and move synchronously with it. When the switch 133 moves through the air vent 122, it causes the seal 134 to fit tightly against the inner wall of the air vent 122.

[0077] The seal 134 may be an elastic rubber component, but is not limited to this.

[0078] See Figure 6 In some optional embodiments, the floor brush assembly 100 is further provided with a swing arm 180, a first position switch 171 and a second position switch 172. The swing arm 180 is connected to the switching switch 133 and moves synchronously with the switching switch 133. During the movement, the swing arm 180 can contact or approach the first position switch 171 and the second position switch 172 respectively. When the swing arm 180 contacts or approaches the first position switch 171, the first position switch 171 generates a first signal, which is used to indicate that the switching switch 133 is in the main suction position. When the swing arm 180 contacts or approaches the second position switch 172, the second position switch 172 generates a second signal, which is used to indicate that the switching switch 133 is in the side suction position.

[0079] The first and second position switches 171 and 172 can automatically identify the position of the switch 133, facilitating intelligent control of the opening or closing of the side air duct 130. By setting a swing arm 180 that is linked to the switch 133, the first and second position switches 171 and 172 do not need to cooperate with the switch 133, making the position setting more flexible.

[0080] Figure 6In the illustrated embodiment, a first signal is generated when the first position switch 171 contacts the swing arm 180, and a second signal is generated when the second position switch 172 contacts the swing arm 180. In some embodiments not illustrated in this application, the first position switch 171 and the second position switch 172 can be non-contact switches, such as proximity switches. In this case, the first signal is generated when the first position switch 171 is close to the swing arm 180 (e.g., a distance of 1mm, 2mm, or millimeters), and the second signal is generated when the second position switch 172 is close to the swing arm 180.

[0081] For example, both the first signal and the second signal can be high-level signals. For instance, taking the first position switch 171 as an example, when the swing arm 180 moves away from the first position switch 171, the first position switch 171 generates a low-level signal, indicating that the switch 133 is not in the main suction position. When the swing arm 180 contacts or approaches the first position switch 171, the first position switch 171 generates a high-level signal (i.e., the first signal), indicating that the switch 133 is in the main suction position. The detection principle of the second position switch 172 is the same and will not be described again.

[0082] The first position switch 171 and the second position switch 172 can be microswitches, but are not limited to them.

[0083] Combination Figure 4 and Figure 6 As shown, in some optional embodiments, when the switching switch 133 is in the main suction position, the switching switch 133 is basically located inside the side air duct 130, and the swing arm 180 is located outside the side air duct 130 and the main air duct 120.

[0084] Based on the foregoing description, since the connection (corresponding to the opening of the side air duct 130) or non-connection (corresponding to the closing of the side air duct 130) between the main air duct 120 and the side air duct 130 is achieved by the cooperation of the switching switch 133 and the air outlet 122, the switching switch 133 needs to be installed inside the side air duct 130. Given the limited space inside the side air duct 130, the first position switch 171, the second position switch 172, and the swing arm 180, which are linked to the switching switch 133, can all be installed outside the side air duct 130, resulting in a more rational layout.

[0085] See Figure 6 In some optional embodiments, the floor brush assembly 100 further includes a drive assembly disposed on the floor brush body 110, the drive assembly being connected to the switch 133 to drive the swing arm 180 and the switch 133 to move.

[0086] The drive assembly provides power for the movement of the switch 133 and the swing arm 180, enabling the automatic movement of the switch 133 and the swing arm 180.

[0087] Figure 6 and Figure 7 In the implementation shown, both the rotating shaft and the switch 133 are mounted on the same linkage shaft 161, which is connected to the drive assembly. The movement of both the switch 133 and the swing arm 180 is rotational, but not limited to rotation. Figure 4 Taking the rotational motion shown as an example: Figure 4 When the central switch 133 is in the main suction position, the seal 134 is sealed to the free end of the switch 133 and the inner wall of the air vent 122. When switching to the side suction position is required, the switch 133 moves along... Figure 4 The arrow is rotated roughly clockwise, allowing the free end of the switch 133 to pass through the air vent 122 and enter the main air duct 120, thus opening the air vent 122. Waste and airflow drawn in through the side suction port 131 and the side air duct 130 can then pass through the air vent 122 into the main air duct 120. The switch 133 needs to be returned to its original position. Figure 4 When the side suction position is shown, switch 133 rotates counterclockwise again. This process is repeated.

[0088] In some implementations, the drive component can also be connected to the swing arm 180, indirectly driving the changeover switch 133 to move via the swing arm 180. Alternatively, the drive component can be connected to both the changeover switch 133 and the swing arm 180 simultaneously.

[0089] See Figure 6 In some optional embodiments, the drive assembly includes a switching motor 160, and the floor brush assembly 100 also includes a controller 150 disposed on the floor brush body 110. The controller 150 is electrically connected to the first position switch 171, the second position switch 172 and the switching motor 160 respectively. The controller 150 can control the switching motor 160 to stop rotating based on the first signal or the second signal.

[0090] The first and second position switches 171 and 172 respectively send signals to the controller 150. For example, the switching motor 160 rotates forward, driving the switching switch 133 to rotate towards the main suction position; the motor rotates in reverse, driving the switching switch 133 to rotate towards the side suction position. A motor protective cover can be installed on the switching motor 160. When the controller 150 receives the first signal, it determines that the switching switch 133 is in the main suction position. If the side air duct 130 needs to be opened at this time, a control command is sent to the switching motor 160 to control the switching motor 160 to rotate in reverse, causing the switching switch 133 to move towards the second position switch 172, until the controller 150 receives the second signal, indicating that the switching switch 133 has reached the side suction position. The controller 150 then controls the switching motor 160 to stop rotating.

[0091] See Figure 9In some optional embodiments, the side air duct 130 includes a guide section 136 and an air inlet section 137. The air inlet section 137 connects the guide section 136 and the side suction port 131, respectively. The inner diameter of the air inlet section 137 increases from the guide section 136 towards the side suction port 131. After the waste enters the air inlet section 137 through the side suction port 131, it then enters the guide section 136 from the air inlet section 137. Because the inner diameter of the air inlet section 137 increases from the guide section 136 towards the side suction port 131, the side suction port 131 can have a larger cross-sectional area, which can improve the cleaning efficiency of the baseboard area.

[0092] See Figure 10 In some alternative embodiments, the bristles 138 are arranged in an outward-expanding shape around the side suction port 131.

[0093] The bristles 138, which are arranged in an outward-expanding shape, can also expand the negative pressure and increase the effective adsorption range at the side suction port 131.

[0094] See Figure 8 In some embodiments, the floor brush body 110 includes a bottom shell 112 and a top shell 111 connected to the bottom shell 112. The bottom shell 112 is provided with a main suction port 121; the top shell 111 is provided with a side suction port 131.

[0095] In some other implementations, the side suction port 131 may also be located at other positions on the bottom shell 112 or the brush body 110.

[0096] Example 2

[0097] See Figure 1 Example 2 provides a cleaning device, which includes the floor brush assembly 100, body 200, main motor 230 and handle 220 described in Example 1. The body 200 is connected to the floor brush assembly 100 and the handle 220 respectively. The main motor 230 is located on the body 200 and can generate at least a suction flow through the main suction port 121.

[0098] Since Embodiment 2 uses the floor brush component 100 of Embodiment 1, Embodiment 2 has the same technical effects as Embodiment 1, and will not be described again.

[0099] Example 3

[0100] Example 3 provides a control method for a cleaning device. As mentioned above, the cleaning device includes a floor brush assembly 100, which includes a floor brush body 110 and a cleaning component 140. The cleaning component 140 is connected to the floor brush body 110 and contacts the surface to be cleaned to clean the surface. The bottom of the floor brush body 110 is provided with a main suction port 121, and the side of the floor brush body 110 is provided with a side suction port 131.

[0101] In this embodiment, the execution entity of the control method can be a controller installed in the cleaning device or a controller installed in the base, wherein the base is used to support the cleaning device for at least charging and self-cleaning. Alternatively, the execution entity can also be a server corresponding to the cleaning device and the base. This server is located in the cloud, connected to the cleaning device via a network, and issues user commands to the cleaning device and the base, or forwards user commands sent by the user through a terminal device (such as a mobile phone, wearable device, or computer) to the cleaning device and the base.

[0102] The control method in Example 3 is illustrated using the controller in the cleaning equipment as the executing entity.

[0103] Based on the foregoing description, see Figure 11 The control method of Embodiment 3 includes: step S110, during the cleaning operation of the cleaning device, in response to the side suction command, controlling the cleaning device to start the side suction mode so that the cleaning device cleans the baseboard area through the side suction port 131, wherein, when the cleaning device is in the side suction mode, at least the side suction port 131 can conduct and suck away the dirt in the baseboard area.

[0104] "Side suction port 131 can be connected" means that when the main motor 230 is working, the side suction port 131 can generate negative pressure, and the negative pressure can suck away the garbage in the baseboard area through the side suction port 131.

[0105] In some optional embodiments, the floor brush body 110 further includes a main air duct 120 and a side air duct 130, with the main suction port 121 serving as the inlet of the main air duct 120 and the side suction port 131 serving as the inlet of the side air duct 130; the step of controlling the cleaning device to activate the side suction mode in response to a side suction command includes:

[0106] In response to the side suction command, the side air duct 130 is opened so that the side suction port 131 is opened.

[0107] For example, a duct valve can be installed inside the side air duct 130 to control the flow of air in the side air duct 130. By controlling the position of the duct valve, the side air duct 130 can be opened or closed, and the side suction port 131 can be opened or closed accordingly.

[0108] When cleaning the baseboard area is required, the cleaning equipment can enter side suction mode. In side suction mode, both the side air duct 130 and the main motor 230 are activated.

[0109] In some implementations, duct valves can be provided for the side duct 130 and the main duct 120 respectively, and whether the side duct 130 and the main duct 120 are connected is achieved by controlling their respective duct valves. In other implementations, a switching valve can be provided, which can be in one of three states: 1. The switching valve connects the side duct 130 and closes the main duct 120; 2. The switching valve closes the side duct 130 and connects the main duct 120; 3. The switching valve connects both the main duct 120 and the side duct 130. In the implementation illustrated in this application, as shown in the aforementioned embodiment 1, an air passage 122 is provided on the side wall of the main duct 120. When the air passage 122 is opened using the switching switch 133, the side duct 130 and the main duct 120 are connected. When the switching switch 133 covers the air passage 122, the side duct 130 is closed, but the main duct 120 is connected.

[0110] Side-suction commands can be generated automatically by the cleaning equipment. For example, the floor brush assembly 100 has a distance sensor on its side. When the distance sensor detects the baseboard area, it automatically generates a side-suction command and activates the side-suction mode. Alternatively, side-suction commands can also be generated passively, such as when a user sends a side-suction command to the controller via a button on the cleaning equipment.

[0111] In some optional embodiments, as described above, the floor brush assembly 100 further includes a switch 133, which is movable relative to the floor brush body 110 and has at least a main suction position and a side suction position. Step S110 includes: Step S111, when a side suction command is received and the switch 133 is in the main suction position, controlling the switch 133 to move to the side suction position to activate the side suction mode, wherein when the switch is in the side suction position, both the side suction port 131 and the main suction port 121 are conductive.

[0112] Taking the aforementioned implementation method of setting air vent 122 and switch 133 as an example, switch 133 is located in Figure 4 When the air vent 122 is covered, the switch 133 is in the main suction position. At this time, the main air duct 120 is open and the main suction port 121 is open, but the side air duct 130 and the side suction port 131 are closed (also known as closed). When the switch 133 is turned downwards to open the air vent 122, the side air duct 130 and the main air duct 120 are open, and both the side suction port 131 and the main suction port 121 can suck up the garbage.

[0113] See Figure 12 , Figure 12The micro switch includes the aforementioned first stop switch 171 and second stop switch 172. When the user needs to clean the baseboard area, they send a side suction command to the controller via a button. Communication between the button and the controller is achieved through high and low level signals. The controller determines the position of the control switch based on the received signal from the micro switch. If the switch 133 is in the main suction position, a control command is sent to the switching motor 160, which controls the switch 133 to move towards the side suction position. If the switch 133 is already in the side suction position, its current position is maintained.

[0114] In some alternative embodiments, in response to a side-suction command, controlling the cleaning device to activate a side-suction mode, the method further includes:

[0115] Upon receiving a side suction stop command, the control switch 133 is switched from the side suction position to the main suction position to turn off the side suction mode; wherein, when the switch 133 is in the main suction position, the side suction port 131 is in the closed state and the main suction port 121 is in the on state.

[0116] As mentioned earlier, floor cleaning is the more frequent task for users compared to cleaning the baseboard area. Upon receiving the side suction stop command, the control switch motor drives the switch 133 to automatically return to the main suction position, closing the side air duct 130, making it more convenient for users to continue performing floor cleaning.

[0117] Similar to the aforementioned side-suction command, the side-suction stop command can also be generated automatically by the cleaning device or passively by the user through pressing a button. This will not be described again here.

[0118] For example, the controller is a microcontroller unit (MCU), but the controller may also include other devices that can have control functions.

[0119] The controller and the switching motor 160 communicate via PWM (Pulse Width Modulation) signals.

[0120] In some optional embodiments, the floor brush assembly 100 further includes a switching motor 160, a first position switch 171, and a second position switch 172. The switching motor 160 is used to control the movement of the switching switch 133. The switching motor 160 is electrically connected to the first position switch 171 and the second position switch 172 respectively. The first position switch 171 can generate a first signal, and the second position switch 172 can generate a second signal. The first signal is used to indicate that the switching switch 133 is in the side suction position, and the second signal is used to indicate that the switching switch 133 is in the main suction position. The control method further includes: controlling the switching motor 160 to stop rotating when the first signal is received.

[0121] If the first signal is not received, it indicates that the switching switch 133 has not reached the side suction position, and the switching motor 160 needs to be controlled to continue rotating until the first signal is received.

[0122] The structure, side suction position, and main suction position control principle of the floor brush assembly 100 in Example 3 are the same as those in Example 1, and will not be described again.

[0123] See Figure 13 The control method of this application embodiment will be further described using the example of activating the side suction mode by pressing a button. The control method includes:

[0124] Step S10: The user presses the button, and the controller prepares to switch to the side suction mode based on the side suction command sent by the button.

[0125] Step S20: If the switching switch 133 is not in the side suction position, control the switching motor 160 to drive the switching switch 133 to rotate toward the second position switch 172.

[0126] Step S30: Determine whether the switching switch 133 has reached the side suction position. If the controller does not receive the second signal, it is determined that the switching switch 133 has not reached the side suction position, and step S20 is executed. If the controller receives the second signal, it is determined that the switching switch 133 has reached the side suction position, and step S40 is executed.

[0127] Step S40: Control the switching motor 160 to stop rotating and run the side suction mode.

[0128] Step S50: Determine if the user has instructed to switch to main suction mode. If the user has not instructed to switch to main suction mode via button, proceed to step S40. If the user has instructed to switch to main suction mode via button, proceed to step S60.

[0129] Step S60: Control the switching motor 160 to drive the switching switch 133 to rotate toward the first position switch 171.

[0130] Step S70: Determine whether the switch 133 has reached the main suction position. If the controller does not receive the first signal, it is determined that the switch 133 has not reached the main suction position, and step S60 is executed. If the controller receives the first signal, it is determined that the switch 133 has reached the main suction position, and step S80 is executed.

[0131] Step S80: Control the switching motor 160 to stop rotating and run the main suction mode.
