Description

Technical Field

[0001] This application relates to the field of cleaning appliance technology, and in particular to a cleaning brush device and cleaning equipment. Background Technology

[0002] This section provides only background information relevant to this application and is not necessarily prior art.

[0003] Vacuum cleaners, floor scrubbers, and robotic vacuum cleaners are popular among users because they are efficient at cleaning and free up users' hands. These cleaning devices primarily target two categories of surfaces: hard floors and soft carpets. Ideally, for cleaning ordinary hard floors, the suction power required by the cleaning device is not high; however, for soft materials like carpets, dust and dirt easily get trapped in the crevices of the fibers, requiring increased suction power for deep cleaning. Currently, during the cleaning process, users typically adjust the cleaning power of the device based on their own judgment. This subjective approach, combined with manual adjustments to cleaning power, lacks intelligence and leads to problems such as low cleaning efficiency, reduced battery life, and a poor user experience. Utility Model Content

[0004] The purpose of this application is to at least alleviate the technical problems of low cleaning efficiency and reduced machine battery life in cleaning equipment. This purpose is achieved through the following technical solution:

The brush holder has a bottom wall facing the surface to be cleaned, the cleaning surface detection component is mounted on the bottom wall, and the detection end of the cleaning surface detection component is set facing the surface to be cleaned. The cleaning surface detection component is configured to detect the material type of the surface to be cleaned and output the detected material type information.

[0006] The cleaning brush device according to this application can be applied to cleaning equipment such as vacuum cleaners and robotic vacuum cleaners. By setting a cleaning surface detection component on the brush holder, and the orientation of the detection end of the cleaning surface detection component is the same as the orientation of the brush holder towards the surface to be cleaned (first surface), the cleaning surface detection component can detect the material of the surface to be cleaned when the cleaning equipment performs cleaning operations. In this way, based on the material type information fed back by the cleaning surface detection component, the user or the cleaning equipment itself can adjust the cleaning power of the cleaning equipment in a timely manner according to the material type information. For example, it can be adjusted to a larger cleaning power on soft floors and a weaker cleaning power on hard floors, which improves the intelligence of the cleaning equipment using this cleaning brush device. The cleaning equipment can clean on demand, improve resource utilization, and extend the endurance of the cleaning equipment.

[0039] Exemplary embodiments of this application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0040] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0041] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0042] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations.

[0043] Research has found that cleaning equipment such as household vacuum cleaners, floor scrubbers, and robotic vacuum cleaners need to clean both hard floors and soft carpets. For cleaning ordinary hard floors, the suction power required by the cleaning equipment is not high; however, for soft materials like carpets, dust and dirt easily get trapped in the crevices of the fibers, requiring increased suction power for deep cleaning. Currently, cleaning equipment with constant power uses the same suction power for different floor materials. This can lead to insufficient suction power and incomplete cleaning of soft materials like carpets; while for hard materials like tiles and wood panels, it can waste resources and reduce the machine's battery life.

[0044] In some advanced technologies, cleaning devices are equipped with a manual suction power adjustment function, allowing users to manually adjust the suction level, typically offering low and high power modes. Research has found that this manual adjustment method requires user intervention and judgment, resulting in inconsistent timeliness of adjustments. Furthermore, the adjusted power level may not be suitable for the specific floor surface. The overall intelligence of the cleaning device is limited, and issues such as low cleaning efficiency and inadequate battery life remain prominent, negatively impacting the user experience.

[0045] Based on the above research, in order to improve the intelligence of cleaning equipment and alleviate the technical problems of low cleaning efficiency and reduced machine battery life, this application provides a cleaning brush device. The cleaning brush device can be used in cleaning equipment. The cleaning brush device is equipped with a cleaning surface detection component, which can detect the material of the ground surface to be cleaned. The user or the cleaning equipment can adjust the cleaning power of the cleaning equipment in a timely manner based on the detection information fed back by the cleaning surface detection component. The cleaning equipment can clean on demand, improve resource utilization, and extend the battery life of the cleaning equipment.

[0046] like Figures 1 to 11 As shown, the cleaning brush device 100 proposed in this application embodiment includes a brush holder 110 and a cleaning surface detection element 120. The brush holder 110 is defined as a bottom wall 111 facing the surface to be cleaned (e.g., the ground), and the bottom wall 111 has a first surface 1104 facing the surface to be cleaned. The cleaning surface detection element 120 is disposed on the bottom wall 111 so that the cleaning surface detection element 120 is mounted on the brush holder 110. The cleaning surface detection element 120 has a detection end 121, which is positioned facing the surface to be cleaned (e.g., the ground), and the cleaning surface detection element 120 is used to detect the material type of the surface to be cleaned (e.g., the ground) and output the detected material type information.

[0047] The surface to be cleaned is the object that needs to be cleaned, which can be the ground, etc. The detection end 121 and the first surface 1104 can have the same orientation.

[0048] The bottom wall 111 may be provided with an installation structure, and the clean surface detection component 120 can be installed on the bottom wall through the installation structure.

[0049] Optionally, in some implementations, the bottom wall 111 may be partially recessed upwards, so that the first surface 1104 has an upwardly recessed area, and the cleaning surface detection element 120 may be installed in the recessed area.

[0050] Optionally, in some implementations, the bottom wall 111 may also be provided with a mounting hole 1111, and the cleaning surface detection element 120 may be disposed in the mounting hole 1111, or the cleaning surface detection element 120 may be disposed above the mounting hole 1111 and communicate with the first surface 1104 through the mounting hole 1111.

[0051] The cleaning surface detection component 120 can output detected material type information in various ways. For example, the cleaning surface detection component 120 can be connected to the controller 200 of the cleaning equipment. The cleaning surface detection component 120 can send the detected material type information to the controller 200, and the controller 200 can adaptively control the cleaning equipment based on the material type information. As another example, the cleaning surface detection component 120 can also be connected to a display component 300. The cleaning surface detection component 120 can send the detected material type information to the display component 300, causing the display component 300 to display the material type information. The user can adaptively control the cleaning equipment based on the detected material type information. The display component 300 can display image information, voice control information, or text corresponding to the material. The display component 300 can be a built-in display component 300 of the cleaning surface detection component 120 or a display component 300 inherent to the cleaning equipment itself.

[0052] It should be noted that the display component 300 can be directly connected to the clean surface detection component 120 via signal, or the display component 300 can be connected to the clean surface detection component 120 via the controller 200.

[0053] The surface cleaning detector 120 is a detector capable of identifying the material type of the surface to be cleaned (e.g., floor). Specifically, the surface cleaning detector 120 can identify the hardness type of the surface to be cleaned. The surface cleaning detector 120 can classify materials into soft and hard materials based on settings.

[0054] For example, the surface cleaning detection component 120 can be a light sensor. The light sensor includes a transmitting unit, a light receiving module, and a main control module. The transmitting unit emits light signals to the surface to be cleaned (e.g., the ground). The light receiving module receives the reflected light signals emitted by the transmitting unit and converts the reflected signals into electrical signals, which are then transmitted to the main control module. The main control module identifies the hardness or softness of the surface to be cleaned (e.g., the ground) based on the electrical signals. The working principle of the surface cleaning detection component 120 is roughly as follows: it identifies the material type of the surface to be cleaned based on the reflection of light from the surface, determining whether the surface is soft or hard. The surface cleaning detection component 120 can include multiple transmitting units, each capable of emitting light signals of different wavelengths. Based on these different wavelengths, the surface cleaning detection component 120 can analyze the material from multiple dimensions, improving the accuracy of detecting the material type of the surface to be cleaned.

[0055] Optionally, the surface detection component 120 can be an infrared sensor. The infrared sensor is integrated into a housing 122, including a circuit board, infrared emitter, infrared receiver, and other related electrical components built into the housing 122. Both the emitting and receiving ends of the infrared sensor are oriented towards the direction of the first surface 1104. That is, when the cleaning brush device 100 (cleaning equipment) is in a cleaning state, both the emitting and receiving ends of the infrared sensor are oriented towards the surface to be cleaned. The infrared sensor can have a one-transmitter, two-receiver structure, analyzing the two received signals from several dimensions to determine the material type of the surface to be cleaned.

[0056] Optionally, such as Figure 1 , Figures 4 to 9 , Figure 11 As shown, the infrared sensor can be roughly square in structure, with its height direction roughly aligned with the thickness direction Z of the brush holder 110 (the arrangement direction of the first surface 1104 to the second surface 1105). The width and length directions of the infrared sensor can be arranged in any direction roughly parallel to the first surface 1104. For example, as... Figure 7 and Figure 8 As shown, the length direction of the infrared sensor can be arranged along the traveling direction X (front-back direction) of the cleaning brush device 100, such as... Figure 1 , Figures 4 to 6 , Figure 9 As shown, the length direction of the infrared sensor can also be arranged along the left-right direction Y of the cleaning brush device 100 (the direction perpendicular to the walking direction X).

[0057] Understandably, using an infrared sensor as the surface detection element 120, compared to ultrasonic sensors, eliminates the need for a acoustic cavity design. It can accurately identify yoga mats and carpets of various colors and lengths as soft surfaces to be cleaned, improving the accuracy of surface material detection. Furthermore, the infrared sensor is small, simple in structure, and its horizontal placement is unrestricted; it can be placed anywhere on the bottom plane (i.e., the first surface 1104) of the brush holder 110, and it is less likely to interfere with other functional modules.

[0058] The cleaning brush device 100 of this embodiment can be applied to cleaning equipment such as vacuum cleaners and robot vacuums. By setting a cleaning surface detection element 120 on the brush holder 110, the detection end 121 of the cleaning surface detection element 120 is oriented in the same direction as the surface of the brush holder 110 facing the surface to be cleaned (first surface 1104). When the cleaning equipment performs cleaning operations, the cleaning surface detection element 120 can detect the material of the surface to be cleaned. In this way, based on the material type information fed back by the cleaning surface detection element 120, the user or the cleaning equipment itself can adjust the cleaning power of the cleaning equipment in a timely manner according to the material type information. For example, when cleaning a soft surface, the cleaning surface detection element 120 outputs a high-level signal, the power of the cleaning equipment increases, the response speed is fast, and the cleaning power is improved. When cleaning a hard surface, the cleaning surface detection element 120 outputs a low-level signal, the power of the cleaning equipment decreases, and the cleaning power is reduced. This improves the intelligence of the cleaning equipment using the cleaning brush device 100, allowing the cleaning equipment to clean on demand, improving resource utilization, saving manpower, and extending the battery life of the cleaning equipment that is powered by a battery.

[0059] In some embodiments, the cleaning surface detection element 120 is further configured to detect the lifting state of the cleaning brush device 100 and send the lifting state information of the cleaning brush device 100 to the controller 200. The controller 200 is further configured to control the drive mechanism 400 to operate according to the lifting state information of the cleaning brush device 100.

[0060] The raised state of the cleaning brush device 100 refers to whether the cleaning brush device 100 is raised. In other words, the cleaning surface detection element 120 can also be configured to detect whether the cleaning brush device 100 is raised. When the cleaning brush device 100 is raised, its distance from the surface to be cleaned increases. The cleaning surface detection element 120 can detect whether the cleaning brush device 100 is raised by detecting the position or distance of the surface to be cleaned. The cleaning surface detection element 120 can be a light sensor, identifying whether the cleaning brush device 100 is raised based on the reflection of light by the light sensor.

[0061] Optionally, in some implementations, when the cleaning brush device 100 is lifted, the cleaning surface detection element 120 can identify the signal as the same as that of a hard surface to be cleaned; when the cleaning brush device 100 is not lifted and is in the state of performing regular cleaning operations, the cleaning surface detection element 120 outputs corresponding material type information based on the material type of the surface to be cleaned. That is, when the material type information is a hard surface to be cleaned or the cleaning brush device 100 is lifted, the cleaning surface detection element 120 outputs a low level, reducing the power of the cleaning equipment and the cleaning power; when the material type information is a soft surface to be cleaned and the cleaning brush device 100 is in normal cleaning operations, the cleaning surface detection element 120 outputs a high level, increasing the power of the cleaning equipment, improving the response speed, and enhancing the cleaning power.

[0062] Alternatively, in some other implementations, when the cleaning brush device 100 is lifted, the cleaning surface detection element 120 can use this signal as a standby signal; when the cleaning brush device 100 is not lifted and is in the state of performing routine cleaning operations, the cleaning surface detection element 120 further identifies the material type of the surface to be cleaned.

[0063] It should be noted that the lifting state of the cleaning brush device 100 detected by the cleaning surface detection component 120 can be displayed in the display component 300 to help users understand the operation of the cleaning equipment.

[0064] When switching cleaning targets, users typically lift the cleaning device briefly. At this time, the cleaning device can be adjusted to low power or standby mode, which improves cleaning efficiency and resource utilization, increases the battery life of the cleaning device, and enhances the user experience.

[0065] Optionally, the cleaning surface detection element 120 is positioned on the brush holder 110 to avoid the cleaning component 114.

[0066] For example, the cleaning brush device 100 also includes a cleaning component 114 and a drive mechanism 400. The brush holder 110 includes a receiving cavity 1106, the drive mechanism 400 is mounted in the receiving cavity 1106, and the cleaning component 114 is at least partially exposed to facilitate cleaning of the surface to be cleaned, such as... Figure 9 As shown, the cleaning surface detection component 120 can be positioned at the bottom of the corresponding location in the receiving cavity 1106 to avoid the cleaning component 114. The cleaning component 114 is a cleaning execution component used for dusting, scrubbing, sweeping, etc., of the surface to be cleaned (e.g., the floor). It can be a component forming the suction port 116 of the vacuum component, a roller brush 115, or a cleaning cloth holder. The drive mechanism 400 is used to connect to the cleaning component 114, such as the roller brush 115 or the cleaning cloth holder.

[0067] In some embodiments, the controller 200 may also be disposed in the receiving cavity 1106. The cleaning surface detection element 120 may be disposed at the bottom of the brush holder 110 corresponding to the position of the controller element.

[0068] In some embodiments, such as Figure 1 , Figures 4 to 8 As shown, the cleaning brush device 100 also includes a cleaning component 114, which is mounted on the brush holder 110 and disposed at one end of the brush holder 110, while the cleaning surface detection component 120 is disposed at the other end of the brush holder 110.

[0069] For example, along the walking direction X of the cleaning brush device 100 (i.e., the walking direction X during the use of the cleaning equipment), the cleaning component 114 can be disposed at the front end of the brush holder 110, and the cleaning surface detection component 120 can be disposed at the rear end of the brush holder 110.

[0070] By placing the cleaning component 114 and the cleaning surface detection component 120 on opposite sides of the brush holder 110, the cleaning component 114 keeps the stains far away from the cleaning surface detection component 120 during the cleaning process, making it less likely to contaminate the cleaning surface detection component 120 and improving the detection accuracy of the cleaning surface detection component 120.

[0071] like Figure 1 , Figures 4 to 8 As shown, optionally, in some embodiments, the brush holder 110 has an auxiliary walking wheel 113, which is connected to the connecting part 112 of the brush holder 110. That is, the auxiliary walking wheel 113 is connected to the main body of the brush holder 110 through the connecting part 112, and the cleaning surface detection element 120 can be installed on the connecting part 112.

[0072] The connecting part 112 can be integrated with the brush holder 110. When the cleaning brush device 100 is in the normal cleaning operation state, the auxiliary walking wheel 113 contacts the surface to be cleaned and can roll on the surface to be cleaned to reduce the walking resistance of the cleaning brush device 100 and improve the walking smoothness of the cleaning brush device 100.

[0073] Optionally, along the walking direction X of the cleaning brush device 100 (i.e., the walking direction X during the use of the cleaning equipment), the cleaning surface detection element 120 can be disposed between the auxiliary walking wheel 113 and the cleaning component 114, that is, the cleaning surface detection element 120 can be disposed between the auxiliary walking wheel 113 and the cleaning equipment.

[0074] For example, such as Figure 1 , Figures 4 to 8As shown, along the walking direction X of the cleaning brush device 100 (i.e. the walking direction X during the use of the cleaning equipment), a connecting part 112 protrudes from the rear side of the main body of the brush holder 110, and an auxiliary walking wheel 113 is rotatably mounted on the connecting part 112.

[0075] The auxiliary travel wheel 113 can be provided one or more times. For example, one auxiliary travel wheel 113 can be provided on each of the left and right sides of the brush holder 110, and each auxiliary travel wheel 113 corresponds to a connecting part 112. Figure 1 , Figures 4 to 5 , Figure 7 As shown, a clean surface detection component 120 can be installed at the position corresponding to the connecting part 112 on the right side; as Figure 6 and Figure 8 As shown, a cleaning surface detection element 120 can also be provided at the position corresponding to the connecting part 112 on the left.

[0076] In other embodiments, the cleaning surface detection element 120 may also be disposed on the portion of the brush holder 110 for connection with the connecting portion 112. Or, as... Figure 1 , Figures 4 to 7 As shown, in some embodiments, the portion of the brush holder 110 for connection with the connecting portion 112 and the connecting portion 112 together form the mounting area of ​​the cleaning surface detection element 120. That is, a part of the cleaning surface detection element 120 is located at the portion of the brush holder 110 for connection with the connecting portion 112, and another part of the cleaning surface detection element 120 is located on the connecting portion 112.

[0077] Installing the cleaning surface detection component 120 at the position corresponding to the connecting part 112 of the auxiliary walking wheel 113, or installing the cleaning surface detection component 120 at the part of the brush holder 110 for connection with the connecting part 112, can reduce the possibility of mutual interference between the cleaning surface detection component 120 and the cleaning components 114, etc. The component arrangement is more reasonable, which can effectively reduce the possibility of affecting the space occupied by the cleaning brush device 100 due to the setting of the cleaning surface detection component 120.

[0078] According to some embodiments of this application, optionally, Figure 1 , Figures 4 to 9 As shown, the brush holder 110 has a mounting cavity 1103, and the bottom wall 111 has a mounting hole 1111. The mounting hole 1111 corresponds to and communicates with the mounting cavity 1103. The cleaning surface detection element 120 is located in the mounting cavity 1103 and is connected to the side of the bottom wall 111 facing the mounting cavity 1103 (i.e., the inner wall surface of the bottom wall 111). The cleaning surface detection element 120 is positioned corresponding to the mounting hole 1111, and the detection end 121 of the cleaning surface detection element 120 faces the mounting hole 1111.

[0079] For example, the brush holder 110 includes a base 1101 and a cover plate 1102. The cover plate 1102 covers the base 1101, forming a mounting cavity 1103 and a receiving cavity 1106. The wall of the base 1101 facing the surface to be cleaned is a bottom wall 111. A mounting hole 1111 is provided in the base 1101 and passes through the base 1101. A cleaning surface detection element 120 can be disposed in the base 1101 and located in the mounting cavity 1103. The detection end 121 of the cleaning surface detection element 120 detects the surface to be cleaned through the mounting hole 1111.

[0080] It should be noted that, for ease of understanding of the relevant structure, Figure 1 , Figures 4 to 9 The brush holder 110 of the cleaning brush device 100 shown omits the cover plate 1102. Figure 10 The brush holder 110 shown is in the state where the cover plate 1102 is provided.

[0081] Optionally, such as Figures 1 to 9 As shown, the cleaning surface detection component 120 can be disposed on the inner surface of the base 1101, or it can be partially disposed in the mounting hole 1111.

[0082] The cleaning surface detection component 120 is disposed in the mounting cavity 1103, which can provide good protection for the cleaning surface detection component 120 and reduce the possibility of damage to the cleaning surface detection component 120 caused by stains on the surface to be cleaned during the cleaning operation.

[0083] The circumferential contour of the cleaning surface detection element 120 can be located outside the circumferential contour of the mounting hole 1111. This allows the cleaning surface detection element 120 to press against and be fixed to the inner surface of the mounting cavity 1103 (i.e., the surface of the base 1101 opposite to the first surface 1104, the inner surface of the base 1101), improving assembly convenience. Furthermore, the mounting hole 1111 should not interfere with the detection end 121 of the cleaning surface detection element 120 detecting the surface to be cleaned. For example, if the cleaning surface detection element 120 is configured as an infrared sensor, both the transmitting end and the receiving end of the infrared sensor are located inside the circumferential contour surrounding the mounting hole 1111.

[0084] It should be noted that when the drive mechanism 400 is at least partially installed on the brush holder 110, the mounting cavity 1103 of the brush holder 110 for mounting the cleaning surface detection component 120 and the receiving cavity 1106 for mounting the drive mechanism 400 (or controller 200) can be isolated from each other or connected.

[0085] Optionally, a transparent protective cover may be provided on the first surface 1104 corresponding to the position of the mounting hole 1111. The transparent protective cover may be made of a transparent material with excellent light transmittance and may be installed on the mounting hole 1111 in an openable manner.

[0086] According to some embodiments of this application, optionally, such as Figures 1 to 9 As shown, the brush holder 110 is also connected to a limiting member 1112. The limiting member 1112 is disposed in the mounting cavity 1103 and is connected to the part of the brush holder 110 surrounding the mounting hole 1111. The limiting member 1112 is disposed on the outside of the cleaning surface detection member 120.

[0087] The limiting member 1112 can fix and limit the cleaning surface detection member 120. The limiting member 1112 can be a ring-shaped structure arranged around the circumference of the cleaning surface detection member 120. Alternatively, multiple limiting members 1112 can be arranged at intervals along the circumference of the cleaning surface detection member 120, with multiple limiting members 1112 cooperating to form an accommodating space in which the cleaning surface detection member 120 is disposed. The cleaning surface detection member 120 and the limiting member 1112 can be fixed by frictional compression, or the limiting member 1112 can be fixedly connected to the cleaning surface detection member 120 by snap-fit, screws, adhesive bonding, or other methods.

[0088] like Figure 1 , Figure 2 and Figure 3 As shown, in an optional implementation, the base 1101 of the brush holder 110 is provided with limiting members 1112 at both ends of the cleaning surface detection member 120 along its length. The limiting members 1112 are approximately U-shaped groove structures, and the U-shaped groove structures of the two limiting members 1112 face each other to form an accommodating space. The cleaning surface detection member 120 is installed in the U-shaped groove structure of the two limiting members 1112 and is connected to the two limiting members 1112 respectively by glue or buckle.

[0089] The limiting component 1112 and the brush holder 110 (base 1101) can be an integral structure, which can be injection molded as one piece, or formed as one piece by welding or fusion.

[0090] By setting the limiting component 1112, the installation stability of the clean surface detection component 120 can be improved, and the clean surface detection component 120 can be assembled and positioned, thus improving the ease of assembly of the clean surface detection component 120.

[0091] Alternatively, in some implementations, the clean surface detection element 120 is detachably connected to the bottom wall 111.

[0092] For example, the clean surface detection component 120 can be installed with the limiting component 1112 in a detachable manner by means of elastic buckle, screw, interference fit, etc.

[0093] For ease of description, the brush holder 110 is defined to have a second surface 1105, which faces in the opposite direction to the first surface 1104. The second surface 1105 is also the top surface of the cover plate 1102.

[0094] In some embodiments, optionally, along the arrangement direction from the first surface 1104 to the second surface 1105 (which can be understood with reference to the thickness direction Z of the brush holder 110), the detection end 121 of the cleaning surface detection element 120 is spaced apart from the first surface 1104, and the detection end 121 is located on the side of the first surface 1104 closer to the second surface 1105.

[0095] In other words, the detection end 121 of the cleaning surface detection element 120 is located on the upper side of the first surface 1104. When the cleaning brush device 100 performs a regular cleaning operation, the distance between the first surface 1104 and the surface to be cleaned is closer than that between the cleaning surface detection element 120 and the surface to be cleaned.

[0096] When the cleaning brush device 100 performs routine cleaning operations, the first surface 1104 can contact or be close to the surface to be cleaned. The detection end 121 of the cleaning surface detection element 120 is located above the first surface 1104, which can protect the detection end 121 of the cleaning surface detection element 120 and reduce the possibility of damage to the detection end 121 of the cleaning surface detection element 120 by the surface to be cleaned or stains. At the same time, the installation height of the cleaning surface detection element 120 can improve the detection range and detection accuracy of the cleaning surface detection element 120.

[0097] Optionally, when the cleaning brush device 100 performs routine cleaning operations, the distance between the installation position of the detection end 121 of the cleaning surface detection component 120 and the surface to be cleaned can be between 10 mm and 20 mm, specifically, it can be 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, etc.

[0098] This application also provides a cleaning device, including a body, a drive mechanism 400, a controller 200, and a cleaning brush device 100 as proposed in this application or any embodiment of this application. The brush holder 110 of the cleaning brush device 100 is connected to the body, and a cleaning component 114 is provided on the brush holder 110. The drive mechanism 400 is disposed on the body or the brush holder 110 and is connected to the cleaning component 114 for cleaning the surface to be cleaned. The controller 200 is disposed on the body or the brush holder 110 and is electrically connected to the cleaning surface detection element 120 and the drive mechanism 400 respectively. The controller 200 is configured to control the operation of the drive mechanism 400 according to the detection information of the cleaning surface detection element 120.

[0099] Cleaning equipment can include floor scrubbers, vacuum cleaners, and robotic vacuum cleaners. The controller 200 is the intelligent control component of the cleaning equipment, possessing functions such as data acquisition, processing, and transmission. It includes a circuit board and related components integrated on the circuit board. Specifically, the controller 200 can be a programmable logic controller 200 (PLC), etc. The controller 200 can be mounted on the machine body or on the brush holder 110.

[0100] The brush holder 110 can be connected to the body via a connecting device 500, which can connect to a base or other structure. For example, the connecting device 500 may include a plug-in hole, into which the body can be inserted and fixed.

[0101] The electrical connections involved in this embodiment mainly focus on signal connections, that is, the ability for data and signal transmission between the connected components constitutes an electrical connection. For example, the controller 200 and the cleaning surface detection component 120 can be electrically connected via a data cable, and the controller 200 and the drive mechanism 400 can also be electrically connected via a data cable.

[0102] The location of the drive mechanism 400 can be rationally set according to the type of cleaning components 114 and the space utilization of the cleaning equipment. The drive mechanism 400 may include a motor and related transmission components. For example, the motor can drive the cleaning components 114, such as the roller brush 115 and the cleaning cloth support, to rotate and roll to clean the surface to be cleaned through the transmission components. Alternatively, the motor can drive the fan blades and other transmission components to create negative pressure suction so that the cleaning components 114, such as the vacuuming component, can adsorb and clean up debris. The controller 200 can control the cleaning power of the cleaning equipment by controlling the motor, for example, by controlling the motor to adjust the power of the vacuuming mode or the rotation speed of the roller brush 115.

[0103] The cleaning device in this embodiment has the same beneficial effects as the cleaning brush device 100 proposed in this application or any embodiment of this application.

[0104] In some embodiments, the cleaning device further includes a display component 300, which is disposed on the body or the brush holder 110 and connected to the controller 200. The display component 300 is configured to display material type information corresponding to the detection information of the cleaning surface detection component 120.

[0105] The display component 300 can be mounted on the body of the cleaning equipment or the brush holder 110 as needed. For example, such as... Figure 10As shown, the display component 300 can be disposed on the brush holder 110, for example, on the cover plate 1102 of the brush holder 110, specifically on the second surface 1105, so that the user can view the display component 300.

[0106] In some other embodiments, the display component 300 may also be disposed on the body of the machine, for example, on the handle of the floor scrubber.

[0107] The display component 300 can be a display screen that can display the identification result of the material of the surface to be cleaned. For example, it can distinguish between hard and soft materials, including but not limited to Chinese characters (such as hard material or soft material, floor or carpet) and English characters (such as "Floor" for floor, "Carpet" for carpet, etc.). The display component 300 can also be an indicator light that distinguishes materials by turning on and off, or by displaying different colors to distinguish material types.

[0108] Optionally, the cleaning surface detection element 120 is further configured to detect the lifting state of the cleaning brush device 100 and send the lifting state information of the cleaning brush device 100 to the controller 200. The controller 200 is further configured to control the drive mechanism 400 to operate according to the lifting state information of the cleaning brush device 100.

[0109] The controller 200 can also control the display component 300 to display the raised state of the cleaning brush device 100.
