Description

Technical Field

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

[0002] Cleaning equipment is a device that automatically cleans a surface as it moves across it. For example, the surface to be cleaned can be a floor, and the cleaning equipment can include a cleaning robot.

[0003] In related technologies, the human-computer interaction of cleaning robots mainly relies on text prompts, audio alerts, or simple monochrome light-emitting diode (LED) indicator lights via mobile applications (APPs). However, mobile APP interaction requires users to open their phones to check, which is not very convenient. Audio alerts are rather monotonous and easily ignored in ambient noise. In addition, in scenes with strong ambient light, the visibility of indicator lights will decrease significantly, increasing the difficulty for users to identify the status of the cleaning robot and affecting the overall human-computer interaction experience.

[0004] Therefore, how to clearly and intuitively display the status of cleaning equipment under different lighting conditions has become a technical problem to be solved. Utility Model Content

[0005] This application provides a display system, a cleaning device, and a cleaning system that clearly and intuitively display the status of the cleaning device under different lighting conditions.

[0006] In a first aspect, embodiments of this application provide a display system applied to a cleaning device, the display system comprising:

[0007] Controller;

[0008] Display components, including:

[0009] The light source layer is used to generate light, which in turn indicates the status information of the cleaning equipment; the light source layer has a light-emitting surface and a non-light-emitting surface.

[0010] The display panel is positioned on top of the light source layer and is mounted on the housing of the cleaning equipment to display the status information of the cleaning equipment.

[0011] A light guide layer is disposed between the light source layer and the display panel, and the light guide layer is used to guide the light generated by the light source layer to the display panel;

[0012] A dynamic filter layer is located between the light guide layer and the display panel;

[0013] The controller is electrically connected to the light source layer. The controller is used to generate different lighting control commands so that the light source layer can produce different lights according to the lighting control commands. The lights are used to indicate different status information of the cleaning equipment.

[0014] The controller is also electrically connected to the dynamic filter layer to control the light transmission state of the dynamic filter layer according to ambient light conditions.

[0015] This application provides a display system that, through the arrangement of a light source layer and a display panel, connects the light source layer to a controller. This allows the light source layer to generate corresponding light indicating different status information of the cleaning equipment when the controller outputs different light control commands, and presents this information to the user through the display panel. In this way, the user can directly obtain the status information of the cleaning equipment by observing the light on the display panel, without needing to check a mobile phone or other external devices. This improves the intuitiveness and convenience of viewing the status information of the cleaning equipment, thereby enhancing the user experience.

[0016] Based on this, by setting a light guide layer in the display system, since the light guide layer is set between the light source layer and the display panel, the light generated by the light source layer can be effectively guided to the display panel through the light guide layer, thereby improving the uniformity of light, ensuring the consistency of brightness in each area of ​​the display panel, avoiding the problem of local over-brightness or under-brightness, ensuring the clarity and visual effect of status information display, and further enhancing the intuitiveness of human-computer interaction and user experience.

[0017] Furthermore, by setting a dynamic light filter layer in the display system, which is located between the light guide layer and the display panel, and electrically connected to the controller, the light transmittance of the dynamic light filter layer can be controlled according to ambient light conditions. This allows the controller to dynamically adjust the transmittance of light emitted from the light guide layer, ensuring the display panel maintains appropriate brightness and contrast under different ambient light conditions. This guarantees users can accurately identify the status information of cleaning equipment in various lighting environments, improving the environmental adaptability and visibility of the display system. For example, when the ambient light is strong, the controller can control the dynamic light filter layer to increase its transmittance, allowing more light emitted from the light source layer to pass through the display panel, enhancing display brightness to resist ambient light interference. Conversely, when the ambient light is weak, the controller can control the dynamic light filter layer to reduce its transmittance, preventing the displayed content from being too bright and glaring.

[0018] Therefore, by configuring the controller and display components, the different status information of the cleaning equipment can be intuitively presented through changes in the light effect of the light source layer. Simultaneously, the display system can adjust the light transmission state of the dynamic filter layer according to different ambient lighting conditions, ensuring that the display panel can clearly and intuitively display the status of the cleaning equipment under various lighting environments, thereby improving the human-computer interaction and user experience of the cleaning equipment.

[0019] In some embodiments, the dynamic filter layer includes:

[0020] A light filter element covers the light-emitting surface of the light guide layer. The light transmission state of the light filter element is adjustable so that the light filter element has a first light transmission state and a second light transmission state. The light transmittance of the light filter element in the first light transmission state is greater than the light transmittance of the light filter element in the second light transmission state.

[0021] The drive circuit is electrically connected between the filter and the controller.

[0022] The controller is configured to control the filter to switch between a first light-transmitting state and a second light-transmitting state via a drive circuit based on ambient light conditions.

[0023] This configuration allows the light filter to be transparent in its first light-transmitting state, increasing light transmittance and reducing or eliminating light attenuation. In strong ambient light, this enables the display components to overcome interference and maintain sufficient brightness and contrast. In its second light-transmitting state, the light intensity per unit area is reduced, creating a softer, more uniform light emission effect. This prevents excessive glare in low ambient light, improving visual comfort. By adjusting these two light-transmitting states, the display system maintains good visibility under various lighting conditions, facilitating viewing and enhancing the user experience.

[0024] Meanwhile, the drive circuit is electrically connected between the filter and the controller to switch the filter between the first light-transmitting state and the second light-transmitting state under the control of the controller.

[0025] In some embodiments, the filter is a thin-film structure, which is thin and lightweight, allowing the filter to fit tightly onto the light-emitting surface of the light guide layer without significantly increasing the overall thickness of the display system. Simultaneously, the thin-film structure exhibits good flexibility and bendability, maintaining stable optical performance in different installation positions.

[0026] In some embodiments, the thin film structure includes an electrochromic thin film or a dye liquid crystal thin film.

[0027] With this configuration, both the electrochromic film and the dye liquid crystal film can change their light transmission state under the control of the driving circuit, thereby adapting to different lighting environments. This allows the display system to maintain good visibility under various lighting conditions, making it easier for users to view and improving the user experience.

[0028] In some embodiments, the filter is connected to and fixed relative to at least one of the light guide layer and the display panel.

[0029] This configuration ensures that when the light filter is connected to the light guide layer, it fits tightly against the light-emitting surface of the light guide layer. This guarantees uniform light transmission while avoiding interface reflection losses caused by air gaps, thus improving light energy utilization. When the light filter is connected to the display panel, it ensures accurate positioning of the filter on the display panel, preventing light path offset caused by relative displacement. This ensures that the light after passing through the filter can reach the display panel along a preset path, thereby guaranteeing the uniformity and consistency of the display effect.

[0030] In some embodiments, the light filter is bonded to the light guide layer and the display panel respectively by optical adhesives. In this way, the optical adhesives fill the gaps between the light filter and the light guide layer and between the light filter and the display panel, thereby fixing the relative positions and reducing light loss caused by interface reflection. This ensures that the display components can maintain a stable display effect during the operation of the cleaning equipment.

[0031] In some embodiments, the light guide layer has a plurality of microprism structures on the side facing the display panel.

[0032] With this configuration, when light is transmitted to the microprism interface, the microprism structure can control the direction and uniformity of light emission, so that the light is evenly scattered from the predetermined light-emitting surface, and the light is evenly distributed and directionally emitted throughout the entire effective area of ​​the display panel, ensuring that the display panel can maintain good visibility in different environments.

[0033] In some embodiments, an air gap is provided between the light source layer and the light guide layer, wherein the height of the air gap is greater than or equal to 0.1 mm and less than or equal to 0.5 mm.

[0034] When light rays emerge from the light source layer, they propagate through the air gap. Upon reaching the interface between the air and the light guide layer, due to the difference in refractive indices between the two layers, some light rays are refracted and enter the light guide layer, while others are reflected back into the air gap. The reflected light rays continue to propagate through the air gap, and upon encountering the surface of the light source layer, they are reflected again. The direction of propagation constantly changes, creating a diffuse reflection effect. This makes the displayed light softer and more uniform, improving the visibility of the display components and facilitating user viewing.

[0035] If the height of the air gap is too small, the light will not have enough space to propagate within the air gap, resulting in a significant reduction in the number of reflections at the air-light guide layer interface, thus failing to create an effective diffuse reflection effect. This will cause the light-emitting points of the light source layer to be directly projected onto the light guide layer, forming obvious bright spots and dark areas on the display panel, causing uneven display and localized glare problems, and affecting the visual effect.

[0036] If the air gap is too large, the light travels too far within it, resulting in a loss of brightness. Furthermore, an excessively large gap causes excessive light diffusion during multiple reflections, degrading the directionality of the emitted light and reducing the overall brightness and contrast of the display components. In addition, an excessively large gap increases the overall thickness of the display components, hindering the design of slim and lightweight cleaning equipment.

[0037] Therefore, when the height of the air gap is greater than or equal to 0.1mm and less than or equal to 0.5mm, the air gap can be controlled within a suitable range to provide sufficient space for light reflection, so that the light forms a uniform and soft diffuse reflection effect, while avoiding light energy loss and display clarity reduction caused by excessive gap, thus ensuring display brightness and uniformity.

[0038] In some embodiments, the display component further includes an optical filler that fills the air gap.

[0039] This configuration creates an optical path with a continuous refractive index transition. When light passes through the interface between the light source layer and the light guide layer, it can suppress the interface reflection problem caused by the difference in refractive index, allowing light to be transmitted from the light source layer to the light guide layer more efficiently, reducing the loss of light energy during transmission, and thus improving the overall brightness and light energy utilization of the display system.

[0040] In some embodiments, the light source layer includes a light-emitting unit, which includes an LED or a display screen.

[0041] This setup, through zoned and programmed control of the LED beads, allows different positions and quantities of LED beads to be combined to emit light, thereby displaying specific symbols, numbers, or patterns on the display panel for easy viewing by the user. This improves the flexibility of status information display, eliminating the need for users to check the working status of the cleaning equipment via their mobile phones, thus enhancing the user experience.

[0042] Meanwhile, the display screen can directly show graphical interface information, such as the current cleaning progress percentage, remaining battery power, or working mode of the cleaning equipment, further improving the flexibility of status information display.

[0043] The controller is used to generate different lighting control commands so that the light source layer produces different lights according to the lighting control commands. The lights are used to indicate different status information of the cleaning equipment.

[0044] The lighting control command includes at least one type of light emission information from the light-emitting unit, which includes light emission color information, flashing frequency information, on / off information, and display numbers.

[0045] This setup allows different status information to be presented directly to the user through differentiated lighting effects, eliminating the need for external devices and further enhancing the user experience.

[0046] In some embodiments, the light source layer includes multiple light-emitting units arranged sequentially along a preset direction, and the light emission information also includes the lighting order and / or the number of light-emitting units lit. By controlling the sequential lighting of light-emitting units at different positions, a dynamic and flowing light emission effect can be formed, such as a progress bar gradually filling with light, which makes it easier for users to intuitively understand the status information of the cleaning equipment, further enhancing the intuitiveness and convenience of human-computer interaction.

[0047] In some embodiments, the status information includes the cleaning progress, working mode, battery status, and dustbin status of the cleaning equipment;

[0048] There are multiple display components, and the light source layer and dynamic filter layer of each display component are electrically connected to the controller; the display components are used to display at least one of the following: cleaning progress, working mode, power status and dust box status of the cleaning equipment.

[0049] With this setup, the light source layer and dynamic filter layer of each display component are electrically connected to the controller, and each display component corresponds one-to-one with different status information of the cleaning equipment. This allows each display component to be dedicated to displaying one type of status information, ensuring that the display of each status information is independent of each other. This allows users to simultaneously and clearly obtain multiple status information of the cleaning equipment without having to open their mobile phones or use other external devices to view it, thus improving the user experience.

[0050] In some embodiments, the plurality of display components include:

[0051] The first display component is used to display the cleaning progress of the cleaning equipment for easy viewing by the user.

[0052] The second display component is used to display the working mode of the cleaning equipment for easy viewing by the user.

[0053] The third display component is used to display the battery status of the cleaning equipment for easy viewing by the user.

[0054] The fourth display component is used to display the status of the dustbin of the cleaning equipment for easy viewing by the user.

[0055] By displaying different status information of the cleaning equipment through multiple display components, users do not need to open their mobile phones or use other external devices to check. Users can directly obtain the status information of the cleaning equipment by observing the light on the display panel, which improves the intuitiveness and convenience of users to view the status information of the cleaning equipment, thereby improving the user experience.

[0056] Furthermore, by ensuring that the first, second, third, and fourth display components are set up independently to avoid interference between the display of different status information, users can simultaneously identify multiple pieces of information such as cleaning progress, working mode, battery status, and dustbin status, avoiding misreading caused by information overlap or confusion. At the same time, the independent structure facilitates maintenance; if one display component fails, it will not affect the normal operation of other display components, improving the system's reliability and maintainability.

[0057] In some embodiments, the first display component is configured to be located on top of the fan shroud inside the cleaning equipment, so that the user can know the cleaning progress of the cleaning equipment based on the position of the fan shroud, thereby reducing the user's learning cost.

[0058] Alternatively, the display panel in the first display component has a fan cover pattern, and the fan cover pattern is configured to be illuminated when light is generated by the light source layer in the first display component, thereby forming a clear visual identifier. This allows users to intuitively associate the illuminated pattern with cleaning progress information, thereby quickly understanding the status information conveyed by the display area, reducing the user's learning cost, and enhancing the intuitiveness of human-computer interaction and user experience.

[0059] In some embodiments, the second display component is configured to surround the physical buttons of the cleaning device, so that the user can know the working mode of the cleaning device by the position of the physical buttons, thereby reducing the user's learning cost.

[0060] Alternatively, the display panel in the second display component has several operating mode patterns, and the light source layer in the second display component is configured to illuminate one of the operating mode patterns when it generates light. In this way, when the cleaning device is in a certain operating mode, the light source layer in the second display component only illuminates the pattern corresponding to that mode, allowing the user to intuitively and accurately identify the current operating mode of the cleaning device through the illuminated pattern, thus avoiding information confusion and improving the accuracy of the status display.

[0061] In some embodiments, the third display component is configured to surround the area of ​​the cleaning device adjacent to the battery compartment and can display the remaining power of the cleaning device through the housing, so that the user can know the remaining power of the cleaning device based on the location of the battery compartment, thereby reducing the user's learning cost.

[0062] Alternatively, the display panel in the third display component has a battery pattern, and the light source layer in the third display component is configured to illuminate the battery pattern when it generates light, thereby forming a clear visual identifier. This allows users to intuitively associate the illuminated pattern with the remaining battery status, thus quickly understanding the status information conveyed by the display area, reducing the user's learning cost, and enhancing the intuitiveness of human-computer interaction and user experience.

[0063] In some embodiments, the fourth display component is configured to surround the area adjacent to the dust box of the cleaning device and can display the dust box status of the cleaning device through the housing, so that the user can know the status of the dust box by the location of the dust box, thereby reducing the user's learning cost.

[0064] Alternatively, the display panel in the fourth display component has a dust box pattern, and the light source layer in the fourth display component is configured to illuminate the dust box pattern when it generates light, thereby forming a clear visual identifier. This allows users to intuitively associate the illuminated pattern with the dust box status, thus quickly understanding the status information conveyed by the display area, reducing the user's learning cost, and enhancing the intuitiveness of human-computer interaction and user experience.

[0065] In some embodiments, the plurality of display components further include a fifth display component, which is used to provide ambient lighting when the cleaning equipment performs a cleaning operation or after the cleaning operation is completed, in order to enhance the user experience.

[0066] And / or, the fifth display component is used to provide illumination when the ambient light of the cleaning equipment is below a preset value and when human activity is detected, thereby providing auxiliary lighting in low-light environments, enhancing the practicality of the cleaning equipment, and thus improving the user's convenience and experience.

[0067] In some embodiments, the fifth display component is mounted on the circumferential sidewall of the housing. This allows the light generated by the light source layer of the fifth display component to directly illuminate the ground area surrounding the cleaning equipment, providing convenience for users to observe the surrounding environment of the cleaning equipment in low-light conditions. At the same time, the side lighting does not cause direct glare to the user's line of sight, creating a more comfortable lighting experience.

[0068] Alternatively, a fifth display component may be installed within the housing and configured to provide ambient lighting and / or illumination through the circumferential sidewalls of the housing. This method of emitting light through the housing allows for illumination while maintaining the integrity of the cleaning equipment's appearance.

[0069] Secondly, embodiments of this application provide a cleaning device, including:

[0070] case;

[0071] As in any of the preceding embodiments, the display system includes a display panel mounted on the housing to display status information of the cleaning equipment.

[0072] The cleaning equipment provided in this application embodiment has the aforementioned display system, and therefore possesses the beneficial effects of the aforementioned display system. Through the configuration of the controller and display components, different status information of the cleaning equipment can be intuitively presented through changes in the light efficiency of the light source layer. Simultaneously, the display system can adjust the light transmission state of the dynamic filter layer according to different ambient lighting conditions, ensuring that the display panel can clearly and intuitively display the status of the cleaning equipment under complex lighting environments, thereby improving the human-computer interaction effect and user experience of the cleaning equipment.

[0073] In some embodiments, the cleaning device further includes:

[0074] The dust box, located inside the housing, is used to store the dirt and grime generated during the cleaning process, making it convenient for users to clean it.

[0075] The data processing module is electrically connected to the controller in the display system, and the controller is used to generate different lighting control commands based on the operating parameters of the cleaning equipment provided by the data processing module.

[0076] Operating parameters include the cleaning progress parameters of the cleaning equipment, the current working mode of the cleaning equipment, the remaining power of the cleaning equipment, and the status of the dust box of the cleaning equipment.

[0077] This setup establishes a mapping relationship between operating parameters and optical signals, enabling various status information of the cleaning equipment to be presented to the user intuitively through differentiated light effects. In this way, users can grasp the status information of the cleaning equipment simply by observing the display system without relying on external devices such as mobile phones, which improves the convenience of obtaining status information and the directness of human-computer interaction, thereby enhancing the user experience.

[0078] Thirdly, embodiments of this application provide a cleaning system, including:

[0079] The base has a storage space;

[0080] As in any of the preceding embodiments, the cleaning device can be housed within a housing space, and the base is used to charge the base within the housing space.

Through the configuration of the controller and display components, different status information of the cleaning equipment can be intuitively presented through changes in the light effect of the light source layer. Simultaneously, the display system can adjust the light transmission state of the dynamic filter layer according to different ambient lighting conditions, ensuring that the display panel can clearly and intuitively display the status of the cleaning equipment under complex lighting environments, thereby improving the human-computer interaction effect and user experience of the cleaning equipment.

[0102] 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.

[0103] This application provides a cleaning device. The cleaning device may include a cleaning robot, a vacuum cleaner, a floor scrubber, or other equipment capable of cleaning a surface to be cleaned. For example, the surface to be cleaned may be a floor. The following description primarily uses a cleaning robot as an example to illustrate the structure of the cleaning device.

[0104] Figure 1 This is a schematic diagram of the structure of the cleaning device 100 provided in the embodiments of this application. Figure 2 This is a structural schematic diagram of the cleaning device 100 provided in an embodiment of this application from another perspective.

[0105] Please refer to Figure 1 and Figure 2 Specifically, the cleaning device 100 includes a housing 30, which houses and protects the various internal components. The cleaning device 100 also includes a roller brush assembly 20 and a drive unit, both housed within the housing 30. The drive unit drives the roller brush assembly 20 to rotate, performing cleaning operations on the surface to be cleaned. Simultaneously, the cleaning device 100 can also perform mopping operations for a more comprehensive cleaning effect.

[0106] The roller brush assembly 20 includes two roller brushes arranged opposite each other. When the roller brushes rotate, they can cover the lateral area of ​​the surface to be cleaned and push the object to be cleaned from the outside of the roller brushes inward, concentrating it at the main suction port between the two roller brushes.

[0107] The items to be cleaned can be paper scraps, food crumbs, or small, soft debris. Small, soft debris can include, but is not limited to, hair. For example, small, soft debris can also include cotton thread.

[0108] The roller brush assembly 20 also includes side brushes, which are mounted on both sides of the housing 30 to clean the area around walls or furniture, especially corners and edges, and to gather and concentrate the cleaning material to be cleaned at the main suction port to improve the cleaning efficiency of the cleaning device 100.

[0109] Please refer to Figure 1 and Figure 2 The cleaning device 100 also includes a dust box 40, which is used to collect the debris gathered by the roller brush assembly 20. The dust box 40 is connected to the roller brush assembly 20 via a negative pressure system. After the roller brush gathers dust and debris into the main suction port between the two roller brushes, the negative pressure system can suck the debris into the dust box 40 for unified processing by the user, preventing the debris from falling back onto the surface to be cleaned, thereby improving the cleaning effect and efficiency.

[0110] The cleaning equipment 100 also includes a fan shroud 60, which is used to house and fix the fan assembly of the negative pressure system. The fan shroud 60 is connected to the dust box 40 through a sealing structure. When the fan is working, the suction force generated by the fan draws the objects to be cleaned, which are gathered at the main suction port by the roller brush assembly 20, into the dust box 40, preventing dust or debris from being scattered during the cleaning process, thereby ensuring the thoroughness of the cleaning effect and the cleanliness of the environment.

[0111] Please refer to Figure 1 and Figure 2 The cleaning equipment 100 also includes a battery compartment 50, which houses a battery pack that provides power to the cleaning equipment 100. The battery pack provides a continuous power supply to electrical units such as the roller brush assembly 20, the fan assembly, and the controller, enabling the cleaning equipment 100 to perform autonomous cleaning operations without relying on an external power source.

[0112] The cleaning equipment 100 also has physical buttons 70 on its housing 30. These physical buttons 70 are electrically connected to the controller and are used to receive user operation commands. By pressing the physical buttons 70, the user can directly control the cleaning equipment 100 to turn it on and off, switch modes, and perform targeted cleaning.

[0113] In related technologies, cleaning devices typically incorporate Bluetooth communication modules, which transmit device status information to a mobile application (APP) via pairing. Users must open the APP to view the device's status, a cumbersome process resulting in a poor user experience. Some cleaning devices use audible alerts or monochrome indicator lights for status indication; however, audible alerts are easily ignored by ambient noise, and monochrome indicator lights have limited information capacity. Furthermore, in high-light environments, the visibility of indicator lights decreases significantly, increasing the difficulty for users to identify device status and negatively impacting the overall human-computer interaction experience.

[0114] In view of this, this application provides a display system including a controller and a display component. The display component includes a light source layer, a display panel, a light guide layer, and a dynamic light filter layer. The light source layer is electrically connected to the controller, enabling it to generate corresponding light that indicates different state information of the cleaning device 100 when the controller outputs different light control commands. This light is then presented to the user through the display panel, allowing the different state information of the cleaning device 100 to be intuitively presented through changes in the light effect of the light source layer. The light guide layer guides the light generated by the light source layer to the display panel, improving the uniformity of the light and ensuring the display effect of the display panel. The controller is electrically connected to the dynamic light filter layer to control the light transmission state of the dynamic light filter layer according to ambient light conditions. This ensures that the display panel maintains appropriate display brightness and contrast under different ambient light conditions, allowing users to accurately identify device status information under various lighting environments. This improves the environmental adaptability and visibility of the display system, thereby enhancing the human-computer interaction and user experience of the cleaning device 100.

[0115] The display system provided in the embodiments of this application will be further described below with reference to the accompanying drawings.

[0116] Figure 3 Schematic diagram of the structure of the display component 10 provided in the embodiments of this application Figure 1 , Figure 5 This is a schematic diagram of the control logic of the display system provided in an embodiment of this application.

[0117] Please refer to Figure 1 , Figure 3 and Figure 5 This application provides a display system applied to a cleaning device 100. The display system includes a controller 80 and a display component 10.

[0118] The controller 80 is electrically connected to the main control module of the cleaning equipment 100 to obtain the status information of the cleaning equipment 100 and generate different lighting control commands based on different status information. The display component 10 is disposed on the surface of the housing 30 of the cleaning equipment 100 and is electrically connected to the controller 80. It is used to present corresponding optical display effects according to the lighting control commands. This allows the working status of the cleaning equipment 100 to be intuitively displayed through different optical signals, making it easy for users to identify without having to open their mobile phones to check.

[0119] Please refer to Figure 1 , Figure 3 and Figure 5 Specifically, the display component 10 includes a light source layer 1, a display panel 4, and a light guide layer 2.

[0120] The light source layer 1 has a light-emitting surface and a non-light-emitting surface. The controller 80 is electrically connected to the light source layer 1. When the controller 80 generates different light control commands, the light-emitting surface of the light source layer 1 can generate different light according to the light control commands to indicate different status information of the cleaning equipment 100, so that users can view it.

[0121] When the controller 80 generates corresponding lighting control commands based on the different status information of the cleaning equipment 100, the emitting surface of the light source layer 1 can generate a light combination corresponding to the status information, while the non-emitting surface remains dark. Through the contrast between the light-emitting and non-emitting surfaces, the light can be concentrated and emitted from the emitting surface, improving the directionality and recognizability of the display effect.

[0122] Please refer to Figure 1 and Figure 3 The display panel 4 is positioned on top of the light source layer 1. When the light source layer 1 emits light representing different status information according to control commands, the light directly illuminates the display panel 4 and is displayed through it, allowing the status information of the cleaning device 100 to be presented. This way, users can directly obtain the status information of the cleaning device 100 by observing the light emitted from the display panel 4, without needing to check their mobile phones or other external devices. This improves the intuitiveness and convenience of viewing the status information of the cleaning device 100, thereby enhancing the user experience.

[0123] The light guide layer 2 is disposed between the light source layer 1 and the display panel 4, and the light guide layer 2 is used to guide the light generated by the light source layer 1 to the display panel 4, so that the light generated by the light source layer 1 can be effectively guided to the display panel 4, thereby improving the uniformity of light, ensuring the consistency of brightness in each area of ​​the display panel 4, avoiding the problem of local over-brightness or under-brightness, ensuring the clarity and visibility of status information display, and further enhancing the intuitiveness of human-computer interaction and user experience.

[0124] Please refer to Figure 1 , Figure 3 and Figure 5 The display component 10 also includes a dynamic light filter layer 3, which is disposed between the light guide layer 2 and the display panel 4. The controller 80 is also electrically connected to the dynamic light filter layer 3 to control the light transmission state of the dynamic light filter layer 3 according to the ambient light conditions.

[0125] Specifically, the controller 80 can acquire the ambient light intensity of the environment in which the cleaning equipment 100 is located. By controlling the light transmission state of the dynamic light filter layer 3, the controller 80 can dynamically adjust the transmittance of the light emitted from the light guide layer. This ensures that the display panel 4 maintains appropriate display brightness and contrast under different ambient light conditions, ensuring that users can accurately identify the status information of the cleaning equipment 100 in various lighting environments, thus improving the environmental adaptability and visibility of the display system. For example, when the ambient light is strong, the controller 80 can control the dynamic light filter layer 3 to increase the transmittance, allowing more light emitted from the light guide layer 2 to pass through the display panel 4, enhancing display brightness to resist ambient light interference. When the ambient light is weak, the controller 80 controls the dynamic light filter layer 3 to reduce the transmittance, preventing the displayed content from being too bright and glaring.

[0126] Please refer to Figure 1 , Figure 3 and Figure 5 It should be noted that the cleaning device 100 is equipped with an ambient light sensor, which is electrically connected to the controller 80. The ambient light sensor is used to detect the light intensity of the environment in which the cleaning device 100 is located in real time and transmits the detected light intensity signal to the controller 80. The controller 80 determines the intensity of the current ambient light based on the received light intensity signal. Therefore, through the configuration of the controller 80 and the display component 10, the different status information of the cleaning device 100 can be intuitively presented through the changes in the light effect of the light source layer 1. At the same time, the display system can adjust the light transmission state of the dynamic light filter layer 3 according to different ambient light conditions, ensuring that the display panel 4 can clearly and intuitively display the status of the cleaning device 100 under different lighting environments, thereby improving the human-computer interaction effect and user experience of the cleaning device 100.

[0127] Figure 4 Schematic diagram of the structure of the display component 10 provided in the embodiments of this application Figure 2 .

[0128] Please refer to Figure 1 and Figure 4 In some embodiments, the dynamic filter layer 3 includes a filter element 31 and a driving circuit 32.

[0129] The light filter 31 covers the light-emitting surface of the light guide layer 2, and the light transmission state of the light filter 31 is adjustable so that the light filter 31 has a first light transmission state and a second light transmission state.

[0130] Please refer to Figure 4 Specifically, the light transmittance of the filter 31 in the first light-transmitting state is greater than that in the second light-transmitting state. For example, when the filter 31 is in the first light-transmitting state, it exhibits a transparent effect, which increases light transmittance and reduces or eliminates light attenuation. Thus, in strong ambient light, the display component 10 can overcome ambient light interference and maintain sufficient display brightness and contrast. When the filter 31 is in the second light-transmitting state, it can be in a state similar to fogging. In this state, the filter 31 can diffusely reflect light, reducing the light intensity per unit area and creating a soft and uniform light emission effect. This avoids excessive glare in low ambient light, improving visual comfort. By adjusting the first and second light-transmitting states, the display system can maintain good visibility under different lighting conditions, facilitating user viewing and improving the user experience.

[0131] In this embodiment, the state switching of the filter element 31 is controlled by the drive circuit 32. The drive circuit 32 is electrically connected between the filter element 31 and the controller 80. The controller 80 is configured to control the filter element 31 to switch between a first light-transmitting state and a second light-transmitting state according to the ambient light conditions via the drive circuit 32.

[0132] The controller 80 can detect the current ambient light intensity. When the ambient light intensity is higher than a preset threshold, the controller 80 controls the filter 31 to switch to the first light-transmitting state through the drive circuit 32, so that the display light maintains maximum transmittance and ensures the display brightness for easy viewing by the user. When the controller 80 detects that the ambient light intensity is lower than the preset threshold, the controller 80 controls the filter 31 to switch to the second light-transmitting state through the drive circuit 32, so that the display light forms a soft and uniform light emission effect, avoiding excessive glare.

[0133] The displayed light is the light generated by the light source layer 1 and displayed on the display panel 4 after passing through the light guide layer 2 and the dynamic light filter layer 3.

[0134] It should be noted that the specific value of the preset threshold can be adaptively selected according to actual needs, and this embodiment does not impose any restrictions on it.

[0135] In some embodiments, the light filter 31 is a thin film structure. The thin film structure is characterized by its thinness and light weight, which allows the light filter 31 to be tightly attached to the light-emitting surface of the light guide layer 2 without significantly increasing the overall thickness of the display system.

[0136] Meanwhile, the thin film structure has good flexibility and bendability, and can maintain stable optical performance in different installation positions.

[0137] In some embodiments, the thin film structure includes an electrochromic thin film or a dye liquid crystal thin film.

[0138] Please refer to Figure 4 and Figure 5 Specifically, when the thin film structure is an electrochromic thin film, the controller 80 adjusts the light transmittance of the thin film structure by changing the direction of the voltage applied across the thin film structure through the drive circuit 32. When the ambient light is strong, the drive circuit 32 provides a reverse voltage, causing the thin film structure to undergo a reverse chemical reaction to eliminate coloration, thereby placing the thin film structure in the first light transmittance state, ensuring the display brightness of the light and facilitating user viewing. When the ambient light is weak, the drive circuit 32 provides a forward voltage, causing the thin film structure to undergo a chemical reaction to produce coloration, thereby placing the thin film structure in the second light transmittance state, so that the display light forms a soft and uniform luminous effect, avoiding excessive glare.

[0139] The electrochromic film can be a PDLC film, EC film, DLC film, or SECF film, etc. This embodiment does not impose any limitations on this; an appropriate selection can be made according to actual needs.

[0140] Please refer to Figure 4 and Figure 5 When the thin-film structure is a dye-based liquid crystal film, the controller 80 adjusts the light transmittance of the thin-film structure by controlling the electrical connection between the driving circuit 32 and the thin-film structure. When the ambient light is strong, the controller 80 controls the driving circuit 32 to establish an electrical connection with the thin-film structure and apply a working voltage, causing the liquid crystal molecules in the thin-film structure to align in an orderly manner, thus placing the thin-film structure in the first light-transmitting state, ensuring sufficient display brightness for easy viewing. When the ambient light is weak, the controller 80 controls the driving circuit 32 to disconnect the electrical connection with the thin-film structure, causing the liquid crystal molecules in the thin-film structure to align in a disordered manner, thus placing the thin-film structure in the second light-transmitting state, resulting in a soft and uniform light emission effect and avoiding excessive glare.

[0141] Therefore, when the thin film structure is an electrochromic thin film or a dye liquid crystal thin film, it can change its own light transmission state under the control of the driving circuit 32, thereby enabling adaptive adjustment according to different lighting environments. This allows the display system to maintain good visibility under different lighting conditions, making it easier for users to view and improving the user experience.

[0142] Please refer to Figure 4 In some embodiments, the filter 31 is connected to at least one of the light guide layer 2 and the display panel 4 and is fixed relative to it.

[0143] Specifically, the filter element 31 can be connected and fixed to the light guide layer 2 so that the filter element 31 is tightly attached to the light-emitting surface of the light guide layer 2, ensuring uniform light transmission while avoiding interface reflection loss caused by air gaps and improving light energy utilization.

[0144] In some embodiments, the filter element 31 is connected and fixed to the display panel 4, which can ensure the accurate positioning of the filter element 31 on the display panel 4, prevent the light path deviation caused by relative displacement, and ensure that the light after passing through the filter element 31 can be directed to the display panel 4 along a preset path, thereby ensuring the uniformity and consistency of the display effect.

[0145] In other embodiments, the filter 31 can be connected to the light guide layer 2 and the display panel 4 on both sides so that the display assembly 10 forms an integral structure, thereby preventing the filter 31 from shifting under vibration or temperature change conditions, suppressing stray reflections at each optical interface, and improving the directional transmission efficiency of light in the optical path.

[0146] In this embodiment, no restrictions are placed on the connection method between the filter 31, the display panel 4, and the light guide layer 2. An adaptive selection can be made according to actual needs.

[0147] Please refer to Figure 2 and Figure 4 In some embodiments, the light filter 31 is bonded to the light guide layer 2 and the display panel 4 respectively by optical adhesives, so that the optical adhesives fill the gaps between the light filter 31 and the light guide layer 2 and between the light filter 31 and the display panel 4. While achieving relative position fixation, it can reduce light loss caused by interface reflection and ensure that the display component 10 can still maintain a stable display effect during the moving operation of the cleaning equipment 100.

[0148] In this embodiment, the optical adhesive is an optically transparent adhesive, which can reduce light scattering and reflection losses at the interface and ensure light transmission efficiency. At the same time, the elastic properties of the optically transparent adhesive can absorb the thermal stress between the light filter 31, the light guide layer 2 and the display panel 4, prevent interlayer peeling caused by temperature changes and improve the environmental adaptability of the display component 10.

[0149] In other embodiments, the specific material of the optical adhesive can be selected adaptively according to actual needs, and this embodiment does not impose any restrictions on this.

[0150] Please refer to Figure 4In some embodiments, the light guide layer 2 has a plurality of microprism structures on the side facing the display panel 4. By adjusting the arrangement density and arrangement of the microprism structures, the emission direction and uniformity of the light can be controlled when the light is transmitted to the microprism interface, so that the light is evenly scattered from the predetermined light emission surface, and the light is evenly distributed and directionally emitted in the entire effective area of ​​the display panel, ensuring that the display panel can maintain good visibility in different environments.

[0151] Please refer to Figure 3 In some embodiments, an air gap is provided between the light source layer 1 and the light guide layer 2, and the height of the air gap is greater than or equal to 0.1 mm and less than or equal to 0.5 mm.

[0152] Specifically, an air gap is provided between the light source layer 1 and the light guide layer 2. When light is emitted from the light source layer 1, it propagates within the air gap. When the light reaches the interface between the air and the light guide layer 2, due to the difference in refractive indices between the air and the light guide layer 2, some of the light is refracted and enters the light guide layer 2, while some is reflected back into the air gap. The reflected light continues to propagate within the air gap, and upon encountering the light source layer 1, it is reflected again. The direction of propagation constantly changes, thus creating a diffuse reflection effect. This makes the displayed light softer and more uniform, improving the visibility of the display component 10 and facilitating user viewing.

[0153] If the height of the air gap is less than 0.1mm, such as 0.05mm, 0.06mm, or 0.07mm, the light will not have enough space to propagate within the air gap. This will significantly reduce the number of reflections at the air-light guide layer 2 interface, preventing the formation of an effective diffuse reflection effect. Consequently, the light-emitting point of the light source layer 1 will be directly projected onto the light guide layer 2, creating noticeable bright spots and dark areas on the display panel 4. This will result in uneven display and localized glare, affecting the visual effect.

[0154] If the height of the air gap is greater than 0.5mm, such as 0.6mm, 0.7mm, or 0.8mm, the propagation path of light within the air gap is too long, leading to a loss of brightness. Simultaneously, an excessively large gap causes excessive diffusion of light during multiple reflections, resulting in poor directionality of the emitted light and reducing the overall brightness and contrast of the display component 10. Furthermore, an excessively large gap also increases the overall thickness of the display component 10, which is detrimental to the slim and lightweight design of the cleaning device 100.

[0155] Therefore, in this embodiment, the height of the air gap is greater than or equal to 0.1 mm and less than or equal to 0.5 mm, such as 0.2 mm, 0.3 mm or 0.4 mm, which can control the air gap within a suitable range to provide sufficient space for light reflection, so that the light forms a uniform and soft diffuse reflection effect, while avoiding the problem of light energy loss and reduced display clarity caused by excessive gap, and ensuring display brightness and uniformity.

[0156] Please refer to Figure 4 In some embodiments, the display component 10 further includes an optical filler (not shown) that fills the air gap.

[0157] Specifically, in this embodiment, the optical filler is optical silicone, which fills the air gap between the light source layer 1 and the light guide layer 2. The refractive index of the optical silicone matches the refractive index of the light-emitting surface material of the light source layer 1 and the light-incident surface material of the light guide layer 2, thereby forming an optical path with a continuous refractive index transition. This suppresses interface reflection caused by the refractive index difference when light passes through the interface between the light source layer 1 and the light guide layer 2, allowing light to be transmitted from the light source layer 1 to the light guide layer 2 more efficiently, reducing light energy loss during transmission, and thus improving the overall brightness and light energy utilization of the display system.

[0158] It should be noted that this embodiment does not impose any restrictions on the specific materials of the optical filler, and can be adapted to meet actual needs.

[0159] Please refer to Figure 4 In some embodiments, the light source layer 1 includes a light-emitting unit (not shown), which includes an LED or a display screen.

[0160] Please refer to Figure 1 and Figure 3 Specifically, the light-emitting unit can be an LED bead. Multiple LED beads can be arranged according to a preset layout, and the lighting, extinguishing, and brightness of each LED bead can be controlled individually. By partitioning and programming the LED beads, different positions and different numbers of LED beads can be combined to emit light, thereby displaying specific symbols, numbers, or patterns on the display panel 4 for easy viewing by the user. This improves the flexibility of status information display, eliminating the need for users to check the working status of the cleaning equipment 100 via their mobile phones, thus enhancing the user experience.

[0161] Meanwhile, the light-emitting unit can also be a display screen. The display screen can directly show a graphical interface, such as the percentage of the cleaning progress of the cleaning device 100, the remaining power, or the status information such as the working mode, further improving the flexibility of status information display.

[0162] Please refer to Figure 1 , Figure 3 and Figure 5 In this embodiment, the controller 80 can generate different lighting control commands so that the light source layer 1 can generate different lights according to the lighting control commands. The lights are used to indicate different state information of the cleaning device 100.

[0163] Specifically, after acquiring the status information of the cleaning equipment 100, the controller 80 can generate a light control command. The light control command includes at least one light emission information of the light-emitting unit. The light emission information includes light emission color information, flashing frequency information, on / off information, and display numbers, so that different status information can be directly presented to the user through differentiated light effects. In this way, the user does not need to use external devices to view it, which further improves the user experience.

[0164] Please refer to Figure 1 and Figure 3 In some embodiments, the light source layer 1 includes a plurality of light-emitting units arranged sequentially along a preset direction, and the light-emitting information also includes the lighting order and / or the number of light-emitting units.

[0165] Specifically, the light emission information may include both the lighting order of the light emission units and the number of light emission units lit. This embodiment does not impose any restrictions on this.

[0166] By controlling the sequential illumination of light-emitting units at different locations, a dynamic, flowing light effect can be created, thus intuitively indicating the working progress or movement direction of the cleaning device 100. For example, the sequential illumination of light-emitting units can indicate the current cleaning progress. Alternatively, multiple light-emitting units can be illuminated in a specific order to form a progress bar pattern, indicating the cleaning progress or remaining battery power of the cleaning device 100. This facilitates user identification, reduces the learning curve, and further enhances the intuitiveness and convenience of human-computer interaction.

[0167] It should be noted that this embodiment does not limit the specific lighting pattern, the rules of change, or the state information they represent. Different combinations of light effects can be adaptively selected to represent the corresponding state information according to actual application needs.

[0168] Please refer to Figure 2 , Figure 3 and Figure 5 In some embodiments, the status information includes the cleaning progress, operating mode, battery status, and dustbin status of the cleaning device 100. Multiple display components 10 are present, and the light source layer 1 and dynamic filter layer 3 of each display component 10 are electrically connected to the controller 80. The display components 10 are used to display at least one of the cleaning progress, operating mode, battery status, and dustbin status of the cleaning device 100.

[0169] Specifically, the cleaning device 100 includes a sensor unit electrically connected to the controller 80. The sensor unit is used to collect operating parameters and environmental parameters of the cleaning device 100 during the cleaning process. The controller 80 can control the light source layer 1 of each display component 10 to generate light according to the signals from different types of sensors, so as to represent different state information of the cleaning device 100. The display system has multiple display components 10, and the light source layer 1 and dynamic filter layer 3 of each display component 10 are electrically connected to the controller 80 respectively. Each display component 10 corresponds one-to-one with different state information, so that each display component 10 can be dedicated to displaying one type of state information, ensuring that the display of each state information is independent of each other. This allows users to simultaneously and clearly obtain multiple state information of the cleaning device 100 without having to open their mobile phones or use other external devices to view them, thus improving the user experience.

[0170] Please refer to Figure 2 In some embodiments, the plurality of display components 10 include a first display component 10a, a second display component 10b, a third display component 10c, and a fourth display component 10d.

[0171] Please refer to Figure 2 , Figure 3 and Figure 5 Specifically, the controller 80 includes a data processor 81 and a lighting controller 82. The data processor 81 is electrically connected to the sensing unit to receive operating parameters and environmental parameters collected by various sensors, thereby determining the current working state of the cleaning equipment 100. Based on the current working state of the cleaning equipment 100, it converts the data processor 81 into matching lighting control commands and transmits them to the lighting controller 82 to control the corresponding display component 10 for display.

[0172] Please refer to Figure 2 and Figure 5 The data processor 81 may include a first processing module, a second processing module, a third processing module, a fourth processing module, and a fifth processing module. The first processing module controls the light source layer 1 in the first display component 10a to generate corresponding light, so that the first display component 10a displays the cleaning progress of the cleaning device 100.

[0173] In this embodiment, the cleaning progress light effect display of the cleaning device 100 is as follows: when the cleaning progress is 0%, the light effect is red, and only one or a few columns of the light-emitting units of the first display component 10a are lit. As the cleaning progresses, the light-emitting units of the first display component 10a light up sequentially, and the light effect color gradually changes from red to green.

[0174] When the cleaning progress reaches 100%, the light effect is green, and all the light-emitting units of the first display component 10a are lit, dynamically displaying the current cleaning progress for easy viewing by the user. Alternatively, the light-emitting units of the first display component 10a can also be lit in an arranged numerical format, providing a more intuitive numerical display of the current cleaning progress.

[0175] Specifically, the sensing unit includes positioning and navigation sensors and environmental perception sensors. The positioning and navigation sensors include encoders on the drive unit, inertial measurement units (IMUs), and lidar or vision sensors, used to achieve simultaneous localization and mapping (SLAM) and provide data for calculating cleaning progress. The environmental perception sensors can monitor the working environment and status of the cleaning equipment 100 in real time.

[0176] The first processing module can calculate the cleaning progress status of the cleaning equipment 100 by fusing the data collected by the encoder, inertial measurement unit and environmental sensing sensor on the drive device inside the cleaning equipment 100. The light controller 82 can convert the cleaning progress status into corresponding light control commands, thereby controlling the light source layer 1 in the first display component 10a to generate corresponding light, so that the first display component 10a displays the cleaning progress of the cleaning equipment 100.

[0177] Please refer to Figure 2 and Figure 5 In some embodiments, the first display component 10a is configured to be located on top of the fan shroud 60 inside the cleaning device 100 and can display the cleaning progress of the cleaning device 100 through the housing 30.

[0178] Specifically, the top of the fan cover 60 is provided with a groove, and the first display component 10a is embedded in the groove so that the user can view the cleaning progress of the cleaning equipment 100 through the housing 30.

[0179] In this embodiment, the light source layer 1 of the first display component 10a is a ring-shaped LED light strip, and the groove is a ring-shaped groove that matches the ring-shaped LED light strip to facilitate the installation of the first display component 10a. The ring-shaped LED light strip can create a surrounding progress display effect by controlling different numbers of LED beads to light up sequentially. For example, as the cleaning progresses, the illuminated area of ​​the ring-shaped light strip gradually increases in a clockwise or counterclockwise direction. When cleaning is complete, the entire ring-shaped light strip is fully illuminated, thus intuitively and vividly displaying the cleaning progress, making it easy for users to observe and improving the user experience.

[0180] Please refer to Figure 2 and Figure 5In some embodiments, the display panel 4 in the first display component 10a has a fan cover pattern, and the fan cover pattern is configured to be lit up when light is generated by the light source layer 1 in the first display component 10a, thereby forming a clear visual identifier, enabling users to intuitively associate the lit pattern with cleaning progress information, thereby quickly understanding the status information conveyed by the display area, reducing the user's learning cost, and enhancing the intuitiveness of human-computer interaction and user experience.

[0181] Please refer to Figure 2 and Figure 5 The second processing module is used to control the light source layer 1 in the second display component 10b to generate corresponding light, so that the second display component 10b displays the current working mode of the cleaning device 100.

[0182] Please refer to Figure 2 and Figure 5 In this embodiment, the cleaning device 100 has several operating modes, including powerful cleaning, quiet cleaning, recharging, standby, and error reporting. When the cleaning device 100 is in powerful cleaning mode, the light-emitting unit in the second display component 10b can display a deep blue constant light. When the cleaning device 100 is in quiet cleaning mode, the light-emitting unit in the second display component 10b can display a light blue constant light or cycle through periods of light fading and relighting at the frequency of human breathing. When the cleaning device 100 is in recharging mode, it needs to return to its base for charging. The light-emitting unit in the second display component 10b can display a white light and cycle through the direction of movement of the cleaning device 100 to help the user understand the direction of movement. When the cleaning device 100 is in standby mode, the light-emitting unit in the second display component 10b can display a warm yellow constant light while appropriately reducing its brightness. When the cleaning device 100 is in error reporting mode, the light-emitting unit in the second display component 10b can be displayed in red and flash at a high frequency to attract the user's attention, so that the user can discover and deal with the problem in a timely manner.

[0183] Specifically, the sensor unit also includes a fault detection module and a wireless communication module (such as a Wi-Fi / Bluetooth module). The fault detection module includes collision sensors, wheel suspension sensors, and fan stall sensors, used to detect abnormal operating states of the cleaning equipment 100. The wireless communication module can receive external control commands to set and determine the current operating mode of the cleaning equipment 100.

[0184] Please refer to Figure 2 and Figure 5The second processing module determines the current working mode of the cleaning device 100 based on the user's operation signal to the physical button 70 or the external control command received through the wireless communication module. The light controller 82 can convert the current working mode into a corresponding light control command, and detect whether the cleaning device 100 is in an error reporting mode according to the fault detection module, thereby controlling the light source layer 1 in the second display component 10b to generate corresponding light so that the second display component 10b displays the current working mode of the cleaning device 100.

[0185] In some embodiments, the second display component 10b is configured to surround the physical button 70 of the cleaning device 100 and can display the operating mode of the cleaning device 100 through the housing 30. Specifically, in this embodiment, the light source layer 1 in the second display component 10b is an annular LED light strip, and the periphery of the physical button 70 of the cleaning device 100 is provided with a groove for mounting the second display component 10b, so as to facilitate the mounting of the second display component 10b. The annular LED light strip can match the shape of the housing 30 of the cleaning device 100, improving the aesthetics of the cleaning device 100.

[0186] Please refer to Figure 2 and Figure 5 In some embodiments, the display panel 4 of the second display component 10b has several operating mode patterns, and the light source layer 1 of the second display component 10b is configured to illuminate one of the operating mode patterns when it generates light. Thus, when the cleaning device 100 is in a certain operating mode, the light source layer 1 of the second display component 10b only illuminates the pattern corresponding to that mode, allowing the user to intuitively and accurately identify the current operating mode of the cleaning device 100 through the illuminated pattern, thereby avoiding information confusion and improving the accuracy of the status display.

[0187] Please refer to Figure 2 and Figure 5 The third processing module is used to control the light source layer 1 in the third display component 10c to generate corresponding light, so that the third display component 10c displays the remaining power status of the cleaning device 100.

[0188] Please refer to Figure 2 and Figure 5In this embodiment, when the remaining battery power is 100%, the light effect is green, and all the light-emitting units of the third display component 10c are lit. As the cleaning device 100 is used, the light-emitting units of the third display component 10c turn off sequentially, and the light effect color gradually changes from green to red. When the remaining battery power is 0%, the light effect is red, and most of the light-emitting units of the third display component 10c turn off, leaving only one or a few columns lit. This dynamically displays the current remaining battery power status for easy viewing by the user. Alternatively, the light-emitting units of the third display component 10c can also be lit directly in an arrangement to form numbers, providing a more intuitive numerical display of the current remaining battery power status.

[0189] Specifically, the sensor unit also includes a battery management module, which monitors the battery's voltage, current, and temperature in real time to calculate the accurate remaining charge (SOC). The third processing module can calculate the remaining charge status of the cleaning device 100 based on the monitoring data of the battery management module's voltage, current, and temperature. The light controller 82 can convert the remaining charge status into corresponding light control commands, thereby controlling the light source layer 1 in the third display component 10c to generate corresponding light, so that the third display component 10c displays the remaining charge status of the cleaning device 100.

[0190] Please refer to Figure 2 and Figure 5 In some embodiments, the third display component 10c is configured to surround the area of ​​the cleaning device 100 adjacent to the battery compartment 50 and can display the remaining power of the cleaning device 100 through the housing 30. The third display component 10c is disposed on the top of the battery compartment 50, and the light source layer 1 of the third display component 10c is a strip of LED light or a micro display screen to facilitate the installation of the third display component 10c.

[0191] Specifically, when the light source layer 1 of the third display component 10c is a long strip of LED light, the remaining power status can be intuitively indicated by controlling the illumination of different numbers of LED beads. For example, all 10 LED beads lit up indicate sufficient power (100%), and as the power decreases, a corresponding number of beads turn off sequentially. When only one bead remains lit, it indicates insufficient power (10%), requiring timely charging. This provides a simple and intuitive display of the remaining power of the cleaning device 100, allowing users to quickly determine the remaining power.

[0192] When the light source layer 1 of the third display component 10c is a micro-display, the flexibility of the displayed content is greater. The micro-display can directly and accurately display the remaining battery percentage (such as "85%)" in digital form, and can also intuitively display the battery consumption through a progress bar graph. For example, the battery change can be dynamically reflected through a horizontally filled bar graph or a circular progress graph, which enhances the intuitiveness of the display while ensuring the accuracy of the battery information, reduces the difficulty of user recognition, and improves the user experience.

[0193] Please refer to Figure 2 and Figure 5 In some embodiments, the display panel 4 in the third display component 10c has a battery pattern, and the light source layer 1 in the third display component 10c is configured to illuminate the battery pattern when it generates light, thereby forming a clear visual identifier that allows users to intuitively associate the illuminated pattern with the remaining power status, thereby quickly understanding the status information conveyed by the display area, reducing the user's learning cost, and enhancing the intuitiveness of human-computer interaction and user experience.

[0194] Please refer to Figure 2 and Figure 5 The fourth processing module is used to control the light source layer 1 in the fourth display component 10d to generate corresponding light, so that the fourth display component 10d displays the dust box status of the cleaning device 100.

[0195] Please refer to Figure 2 and Figure 5 In this embodiment, when the dust box 40 is not full, the light-emitting unit of the fourth display component 10d can be in an off state. When the dust box 40 is full, the light-emitting unit of the fourth display component 10d is red and flashes slowly to remind the user to clean the dust box 40 in time.

[0196] Specifically, the sensing unit also includes a dustbin sensor, which can be an infrared photoelectric sensor installed on the side wall of the dustbin 40 to detect whether the dustbin 40 is full, thereby providing data on the status of the dustbin 40.

[0197] Please refer to Figure 2 and Figure 5 The fourth processing module can determine the dustbin status of the cleaning device 100 based on the output signal of the infrared photoelectric sensor or differential pressure sensor installed in the dustbin 40. The light controller 82 can convert the dustbin status into a corresponding light control command, thereby controlling the light source layer 1 in the fourth display component 10d to generate corresponding light, so that the fourth display component 10d displays the dustbin status of the cleaning device 100.

[0198] Please refer to Figure 2 and Figure 5In some embodiments, the fourth display component 10d is configured to surround the area adjacent to the dust box 40 of the cleaning device 100 and can display the status of the dust box 40 of the cleaning device 100 through the housing 30.

[0199] Specifically, in this embodiment, the fourth display component 10d is disposed on the top of the dust box 40 or on the housing 30 near the dust box 40, so that the user can clearly understand the specific content displayed by the fourth display component 10d.

[0200] In this embodiment, the light source layer 1 of the fourth display component 10d is a high-brightness red LED. The housing 30 of the cleaning device 100 has a light-transmitting hole corresponding to the LED, so that light can pass through the light-transmitting hole for easy observation by the user.

[0201] Please refer to Figure 2 and Figure 5 In some embodiments, the display panel 4 in the fourth display component 10d has a dust box pattern, and the light source layer 1 in the fourth display component 10d is configured to illuminate the dust box pattern when it generates light, thereby forming a clear visual identifier. This allows the user to intuitively associate the illuminated pattern with the state of the dust box 40, thereby quickly understanding the state information conveyed by the display area, reducing the user's learning cost, and enhancing the intuitiveness of human-computer interaction and user experience.

[0202] Please refer to Figure 2 and Figure 5 In some embodiments, the plurality of display components 10 further includes a fifth display component 10e, which is used to provide ambient lighting when the cleaning device 100 performs a cleaning operation or after the cleaning operation is completed.

[0203] The fifth processing module can acquire the cleaning progress status of the cleaning equipment 100 and divide the cleaning progress status into cleaning in progress and cleaning completed. The light controller 82 can convert the two states of cleaning in progress and cleaning completed into corresponding light control commands, thereby controlling the light source layer 1 in the fifth display component 10e to generate corresponding light.

[0204] Please refer to Figure 2 and Figure 5 Specifically, in this embodiment, when the cleaning device 100 is in the process of cleaning, the light effect of the fifth display component 10e is a solid white, or when the cleaning is completed, the light effect of the fifth display component 10e is a gradual change of multiple colors to celebrate the completion of the cleaning task, create an immersive home atmosphere, and enhance the user experience.

[0205] In some embodiments, the fifth display component 10e is used to provide illumination when the ambient light at the location of the cleaning device 100 is below a preset value and when human activity is detected.

[0206] Specifically, when the ambient light level is below a preset brightness value, the fifth display component 10e enters a standby state. If human movement is detected nearby, the fifth display component 10e automatically illuminates under the drive of the controller 80, emitting soft light for illumination. When the ambient light returns to sufficient level or the human body leaves the detection area, the lighting automatically turns off. This allows the cleaning device 100 to provide auxiliary lighting in low-light environments, enhancing the practicality of the cleaning device 100 and thus improving user convenience and experience.

[0207] Specifically, the sensor unit also includes an ambient light sensor and a human body sensor. The ambient light sensor is mounted on top of the cleaning equipment 100 to detect the intensity of ambient light. The human body sensor can be an infrared pyroelectric sensor or a ToF photoelectric sensor to detect whether someone is approaching.

[0208] The fifth processing module can determine the current ambient brightness and sense whether someone is approaching based on the ambient light sensor and the human body sensor. If the ambient brightness is low and someone is approaching, it can be determined to be in night light mode. The light controller 82 can convert the night light mode into corresponding light control commands, thereby controlling the light source layer 1 in the fifth display component 10e to generate corresponding light so that the fifth display component 10e can provide night lighting.

[0209] Please refer to Figure 2 and Figure 5 In some embodiments, the fifth display component 10e is mounted on the circumferential sidewall of the housing 30 so that the light generated by the light source layer 1 of the fifth display component 10e can directly illuminate the ground area around the cleaning device 100, providing convenience for users to observe the surrounding environment of the cleaning device 100 in low-light environments. At the same time, the side lighting will not cause direct stimulation to the user's line of sight, forming a more comfortable lighting experience.

[0210] In some embodiments, the fifth display component 10e is installed within the housing 30 and is configured to provide ambient lighting and / or illumination through the circumferential sidewalls of the housing 30, thereby enabling the illumination function while maintaining the integrity of the appearance of the cleaning equipment 100 by emitting light through the housing 30.

[0211] Based on the above content, the correspondence between each display component 10 and different status information in this embodiment is shown in Table 1. Table 1 is a list of the correspondence between each display component 10 and the status information of the cleaning device 100.

[0213]

[0214] It should be noted that in this embodiment, the first display component 10a, the second display component 10b, the third display component 10c, the fourth display component 10d, and the fifth display component 10e are independent of each other to avoid mutual interference between the display of various status information. This allows users to simultaneously identify multiple pieces of information such as cleaning progress, working mode, battery status, and dustbin status, avoiding misreading caused by information overlap or confusion. Furthermore, the independent structure facilitates maintenance; when one display component 10 malfunctions, it will not affect the normal operation of other display components 10, improving the reliability and maintainability of the system.

[0215] Furthermore, this embodiment does not impose any restrictions on the specific content indicated by each display component 10 or the light effect design, and can make adaptive selections according to actual needs.

[0218] Please refer to Figure 2 and Figure 3 In some embodiments, the cleaning device 100 further includes a dust box 40 and a data processing module. The dust box 40 is disposed inside the housing 30 to store the dirt generated by the cleaning device 100 during operation, so that the user can clean it in a unified manner.

[0219] The dirt can be a mixture of wastewater generated by the cleaning equipment 100, collected impurities, and dirt generated during the cleaning process. Impurities can include paper scraps, food crumbs, hair, etc.

[0220] Please refer to Figure 2 , Figure 3 and Figure 5In this embodiment, the data processing module is electrically connected to the controller 80 in the display system, and the controller 80 is used to generate different lighting control commands based on the operating parameters of the cleaning equipment 100 provided by the data processing module. The operating parameters include the cleaning progress parameters of the cleaning equipment 100, the current working mode of the cleaning equipment 100, the remaining battery power of the cleaning equipment 100, and the status of the dustbin 40 of the cleaning equipment 100. By establishing a mapping relationship between the operating parameters and optical signals, various status information of the cleaning equipment 100 can be intuitively presented to the user through differentiated lighting effects. This allows the user to grasp the status information of the cleaning equipment 100 without the need for external devices such as mobile phones, simply by observing the display system, thus improving the convenience of status information acquisition and the directness of human-computer interaction, and enhancing the user experience.
