[0032] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0033] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a system, product or device comprising a series of units is not necessarily limited to those units explicitly listed, but may include units that are not explicitly listed or are inherent to these products or devices.

[0034] In this application, terms such as "upper," "lower," "inner," "middle," and "outer" indicate positions or locations based on those shown in the accompanying drawings. These terms are intended to better describe this application and its embodiments and are not intended to limit the devices, elements, or components indicated to specific positions, or to their construction or operation in a specific position.

[0035] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0036] Furthermore, the terms "disposed," "connected," and "fixed" should be interpreted broadly. For example, "connected" can mean a fixed connection, a removable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediary, or an internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0037] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0038] Cleaning equipment, also known as cleaning equipment, floor cleaning machines, or floor scrubbers, is a device that provides cleaning functions and is widely used in daily life. During operation, cleaning equipment primarily uses roller brushes to clean surfaces such as floors and draws wastewater into the cleaning equipment. After cleaning, the roller brushes are typically dirty and require cleaning to prepare for future use.

[0039] When cleaning the roller brush, the user can remove the roller brush from the cleaning device and clean it, or clean the roller brush through the self-cleaning mode.

[0040] Cleaning equipment often comes with a tray. After use or cleaning, users place the cleaning device on the tray to charge it. Furthermore, since the roller brush is often wet, it is prone to mold, bacterial growth, and even odor. Therefore, a UV light is installed on the tray to sterilize the roller brush.

[0041] However, users often forget to install the roller brush. For example, after the user manually disassembles and cleans the roller brush, they forget to install the roller brush on the cleaning device. For another example, after the cleaning device has completed self-cleaning, the user believes that the self-cleaning effect is not ideal, so they manually disassemble the roller brush and clean it, and then forget to install the roller brush on the cleaning device. For another example, if hair, thin wire, etc. are entangled on the roller brush, the user manually disassembles the roller brush and cleans it, and then forgets to install the roller brush on the cleaning device. For another example, after the cleaning device has completed self-cleaning, the user believes that the drying effect is not good, so they disassemble the roller brush and dry it by themselves, and then forget to install the roller brush on the cleaning device. When the user forgets to install the roller brush on the cleaning device and places the cleaning device on the tray, if the sterilization function is activated, the radiation of the ultraviolet lamp exceeds the standard, and the safety is poor.

[0042] Based on this, the embodiments of the present application provide a cleaning system, a method for identifying missing roller brushes, and a tray, which detect whether the roller brush is installed before sterilization. Only when the roller brush is installed will the ultraviolet lamp be turned on to sterilize the roller brush, thereby achieving the purpose of improving safety.

[0043] Figure 1 It is a structural diagram of the cleaning system provided in an embodiment of the present application. Figure 2 It is a partial structural diagram of the floor brush assembly and tray of the cleaning system provided in an embodiment of the present application. Figure 3 This is a structural diagram of the floor brush assembly of the cleaning system provided in an embodiment of the present application when the roller brush cover is not installed.

[0044] Please refer to Figures 1 to 3 The cleaning system provided in the embodiment of the present application includes a cleaning device 100 and a tray 200. The cleaning device 100 is, for example, a handheld cleaning machine, a handheld vacuum cleaner, a handheld floor scrubber, etc. The cleaning device 100 includes a body 11 and a floor brush assembly 12 rotatably connected to the body 11. The body 11 is provided with functional components such as a clean water bucket and a dirty water bucket.

[0045] The floor brush assembly 12 is used to clean work surfaces, among other things. It includes a floor brush body 121, a roller brush 122, a roller brush cover 123, and a roller 124. The roller brush cover 123 and the floor brush body cooperate to form a chamber that accommodates the roller brush 122. During operation, the roller brush 122 adheres to the work surface and maintains a spinning motion, continuously rotating and rubbing against the work surface, thereby cleaning the work surface.

[0046] The rolling wheels 124 are arranged on both sides of the floor brush assembly 12 and are away from the roller brush 122. Driven by the driving motor, the rolling wheels 124 drive the cleaning device 100 to move on the working surface.

[0047] In addition, a sewage suction port is also provided on the floor brush assembly 12, and a sewage suction channel connected to the sewage suction port is provided inside the cleaning device. The cleaning device uses a roller brush 122 to clean the dirt on the working surface, and sucks the dirt on the working surface through the sewage suction port, and the sucked dirt enters the sewage suction channel through the sewage suction port. After the roller brush 122 cleans the solid or liquid dirt on the working surface, it separates the solid and liquid. The roller brush 122 rotates with the central axis as the rotation axis. When the surface of the roller brush 122 contacts and rubs against the working surface, the roller brush 122 can adsorb solid or liquid dirt on the surface, and as the roller brush 122 rotates, the solid or liquid dirt on the surface of the roller brush 122 will detach from the surface of the roller brush 122 due to its own gravity or external action. The solid or liquid dirt detached from the surface of the roller brush 122 will be sucked into the sewage suction channel by the sewage suction port, thereby completing the cleaning of the working surface.

[0048] Please refer to Figure 3 The floor brush body 121 is further provided with a light source 125, which includes but is not limited to LED lamp beads, bulbs and other light-emitting elements. When LED lamp beads are selected as the light source 125, they can be conveniently embedded in the floor brush body 121 through a light board.

[0049] The tray 200 is also called a base station, a pedestal, a workstation, a maintenance station, etc., and is used to place the cleaning device 100. For example, after the user has finished using the cleaning device 100, he places it on the tray 200. The cleaning device 100 can be charged, self-cleaned, sterilized, etc. on the tray 200. The tray 200 includes a tray body 21, a sensing component 22, a sterilization component 23, a processor, a accommodating area 24, a charging component 25, a limiting portion 26, an accommodating portion 27, etc., and the processor is not shown in the figure. Among them, the bottom of the accommodating area 24 has a groove, and the sensing component 22 and the sterilization component 23 are arranged in the groove. The charging component 25 is used to charge the cleaning device.

[0050] The limiting portion 26 is used to accommodate at least a portion of the scroll wheel 124. The limiting portion 26 is formed by the interaction of grooves and / or protrusions provided on the tray body 21 of the tray 200. The limiting portion 26 can limit the horizontal movement of the scroll wheel 124, and the protrusions within the limiting portion 26 provide a certain degree of support for the cleaning device 100. This improves the stability and safety of the cleaning device 100 and the tray 200.

[0051] The accommodating portion 27 is used to accommodate cleaning accessories used with the cleaning system, such as spare roller brushes, body extensions, etc. Users can place their usual cleaning accessories in the accommodating portion 27 according to actual use needs, which is convenient for users to use and improves the cleaning efficiency of users.

[0052] In addition, in order to ensure that the cleaning device 100 is stably placed on the tray 200 and avoid tilting or shaking, the end surface of the tray body 21 is configured to be shaped to match the bottom of the floor brush body 121. The accommodating area 24 is configured to be shaped to match the surface of the roller brush 122, for example, the accommodating area is a circular arc groove structure.

[0053] When the cleaning device 100 is placed on the tray 200, the sensing component 22 is configured to capture the light intensity of the light emitted by the light source 125 and input the resistance value corresponding to the light intensity to the processor. The processor is configured to determine whether the roller brush 122 is installed on the floor brush body 121 based on the resistance value, and then control the switch of the sterilization component 23 according to the recognition result.

[0054] Please refer to Figure 2 When the washing machine 100 is placed on the tray 200, if the roller brush 122 is installed on the floor brush body 121, the roller brush 122 is located within the accommodating area 24. At this time, if the light source 125 is illuminated, the light is blocked by the roller brush 122, and the sensor component 22 in the groove can only partially sense, or even not sense, the light emitted by the light source 125. The processor determines that the light intensity is very low and assumes that the roller brush 122 is not installed, thereby disabling the activation of the sterilization component 23, thereby preventing excessive radiation and ensuring safety.

[0055] If the roller brush 122 is not installed on the floor brush body 121, the roller brush cavity formed by the floor brush body 121 and the roller brush cover 123 is empty and unobstructed. At this point, if the light source 125 illuminates, the light fills the entire roller brush cavity and reaches the accommodating area 24, causing the sensor component 22 in the groove of the accommodating area 24 to sense the strong light. The processor determines that the light intensity is relatively high and assumes that the roller brush 122 is installed, requiring disinfection. It then activates the sterilization component 23 to perform the sterilization operation.

[0056] After the user places the cleaning device 100 on the tray 200, the self-cleaning function is activated. During or after the self-cleaning process, the roller brush 122 rotates under the control of the motor. The sterilization component 23 activates and emits ultraviolet light for sterilization, which irradiates a portion of the surface of the roller brush 122. As the roller brush 122 rotates, the ultraviolet light from the sterilization component 23 reaches the entire surface of the roller brush 122, sterilizing and disinfecting it. This reduces bacterial growth on the surface of the roller brush 122, prevents bacterial growth and odor generation, and extends the life of the roller brush 122.

[0057] The cleaning system provided in the embodiment of the present application includes a cleaning device and a tray. The cleaning device includes a body and a floor brush assembly. The floor brush assembly includes a floor brush body and a detachably mounted roller brush. The floor brush body is provided with a light source. The tray includes a tray body, a sensing assembly, a sterilization assembly, and a processor. The tray body is provided with a receiving area for accommodating the roller brush. The bottom of the receiving area is provided with a groove. The sensing assembly and the sterilization assembly are provided in the groove. When the cleaning device is placed on the tray, the sensing assembly is configured to capture the light intensity emitted by the light source and input the light intensity to the processor. The processor is configured to determine whether the roller brush is installed on the floor brush body based on the light intensity, and then control the sterilization assembly to switch on and off based on the recognition result. With this solution, whether the roller brush is installed is detected before sterilization. Only when the roller brush is installed is the ultraviolet lamp turned on to sterilize the roller brush, thereby achieving the purpose of improving safety.

[0058] Optionally, in the above embodiment, the floor brush assembly 142 further includes a roller brush cover 123 located above the roller brush 122 , and the roller brush cover 123 covers the roller brush 122 in an arc shape on one side facing the roller brush 122 .

[0059] The roller brush cover 123 and the floor brush body 121 form a semi-enclosed roller brush chamber, in which the roller brush 122 is disposed. The floor brush body 121 and the roller brush cover 123 are detachably connected, for example, by snap-fitting or screwing, to facilitate removal of the floor brush body 121 and the roller brush cover 123, thereby facilitating maintenance of the roller brush 122 and other components within the chamber.

[0060] The roller brush 122 is connected to the floor brush body 121 via a rotating shaft, and can be powered by a motor or other power device to provide rotational power, so that the roller brush 122 can be rotatably installed in the accommodating cavity.

[0061] A light guide plate 126 is provided on the roller brush cover 123. When the roller brush cover 123 is covered on the floor brush body 121, the light generated by the light source 125 enters the light guide plate and generates and outputs a first light path and a second light path. The first light path is parallel to a first direction, and the angle between the second light path and the first direction is configured to guide the second light path toward the accommodating area 24. The first direction is the front-back direction of the cleaning device. For example, please refer to Figure 4A and Figure 4B .

[0062] Figure 4A This is a schematic diagram of the first light path and the second light path when the roller brush is installed in the cleaning system provided by the embodiment of the present application. Figure 4A When the roller brush 122 is mounted on the floor brush body 121, light emitted by the light source 125 passes through the light guide plate 126 to generate two light paths, namely, a first light path 31 indicated by a solid arrow and a second light path 32 indicated by a dashed arrow. The first light path 31 is parallel to the front-to-back direction of the cleaning device, and the second light path 32 is at a certain angle to the first light path 31. This angle is, for example, between 30 degrees and 80 degrees, and is not limited in this embodiment of the present application, as long as the second light path can be guided toward the accommodating area 24.

[0063] Please refer to Figure 4A The first beam 31 shines toward the front of the cleaning device and can be used for ambient lighting, for example. The second beam 32 is directed toward the receiving area 24. Because the roller brush 122 is mounted on the floor brush body 121, it blocks the propagation of the second beam 32. Therefore, the second beam 32 shines directly onto the roller brush 122, sterilizing it. The groove in the receiving area 24 of the tray 200 is located below the roller brush 122, preventing the sensor assembly 22 in the groove from capturing the second beam 32.

[0064] In the embodiment of the present application, the sensing component 22 is, for example, a photosensor capable of sensing changes in light intensity. Assuming that the cleaning device 100 is not placed on the tray 200, the state in which the sensing component 22 captures natural light is the initial state, and the resistance value in the initial state is X. When the cleaning device 100 is placed on the tray 200, the sensing component 22 is unable to capture natural light and the second light 32. At this time, the resistance value of the sensing component 22 increases to X1, where X1>X. After the processor determines that X1>X, it controls the sterilization component 23 to activate, thereby sterilizing the roller brush 122.

[0065] Figure 4B This is a schematic diagram of the first light path and the second light path when the roller brush is not installed in the cleaning system provided by the embodiment of the present application. Figure 4BThe second light beam is directed toward the accommodating area 24. Because the roller brush 122 is not mounted on the floor brush body 121, the second light beam 32 is directed toward the accommodating area 24. The sensor component 22 captures the second light beam 32, and its resistance decreases to X2, where X2 < X. After the processor determines that X2 < X, it controls the sterilization component 23 to shut down to prevent excessive radiation.

[0066] By adopting this solution, a light guide plate is set up to divide the light emitted by the light source into a first path and a second path of light. The second path of light is directed towards the accommodating area, which makes it easier for the sensing component to accurately detect changes in light intensity, thereby facilitating the tray to accurately identify whether the roller brush is installed, thereby improving the accuracy of roller brush installation identification.

[0067] Optionally, in the above embodiment, the roller brush cover 123 includes an upper cover 1231 and a lower cover 1232, and the light guide plate 126 is disposed between the upper cover 1231 and the lower cover 1232. For example, please refer to Figures 5A to 5D , Figure 5A This is an overall diagram of the floor brush assembly of the cleaning device in the cleaning system provided in an embodiment of the present application. Figure 5B yes Figure 5A Schematic diagram of the structure of the middle roller brush cover, Figure 5C yes Figure 5B Side view of Figure 5D yes Figure 5A Exploded diagram of .

[0068] Please refer to Figures 5A to 5D The roller brush cover 123 includes an upper cover 1231 and a lower cover 1232, with a light guide plate 126 disposed between them. The light guide plate 126 and the fixing components on the roller brush lower cover 1232 are interspersed. The light guide plate 126 has multiple input ports, which are arranged in parallel. Different input ports correspond to different light sources. Between adjacent input ports is a fixing component on the lower cover 1232, which is used to detachably mount the roller brush cover 123 to the floor brush body 121. The light guide plate 126 can be, for example, a hollow structure or a highly transparent solid structure.

[0069] The roller brush cover 123 is also provided with a button 1233 to facilitate the user to disassemble the roller brush cover 123, etc.

[0070] With this solution, the light guide plate is arranged between the upper cover and the lower cover of the roller brush cover, which is conducive to a compact structure and reduces the thickness of the floor brush assembly.

[0071] Optionally, in the above embodiment, at least two light sources 125 are provided on the floor brush body 121 , and a line connecting the at least two light sources 125 is parallel to a second direction, which is the direction of the rotation axis of the roller brush 122 .

[0072] Please refer to Figure 3 and Figure 5D At least two light sources 125 are provided on the floor brush body 121. The light sources 125 are arranged at intervals and correspond one to one with the input ports of the light guide plate 126. The light sources 125 are, for example, LED lamp beads, bulbs, or other light-emitting elements. The light sources are embedded in the floor brush body 121 and are evenly arranged to facilitate uniform light output.

[0073] By adopting this solution, multiple light sources are arranged at intervals on the floor brush body, so that when the roller brush is not installed, each position of the groove in the tray accommodating area can receive the second light, which facilitates the flexible deployment of the sensing component.

[0074] Optionally, in the above embodiment, the sterilization component 23 includes at least two ultraviolet lamps 231 arranged at intervals in the extending direction of the groove, and the sensing component 22 includes at least one photosensor 221 arranged in the extending direction of the groove.

[0075] Figure 6 Schematic diagram of the tray of the cleaning system provided in the embodiment of the present application. Figure 6 The end surface of the groove of the tray 200 accommodating area 24 can be rectangular or semicircular, and at least one row of sterilization components 23 is set at the bottom of the groove. Each row of sterilization components 23 includes at least two ultraviolet lamps arranged at intervals in the extension direction of the groove. The extension direction of the groove is parallel to the direction of the rotation axis of the roller brush. Figure 6 The black filled square is the purple light.

[0076] When the end surface of the groove is rectangular, the groove has a bottom surface and two side surfaces, and the sterilization assembly 23 can be installed on at least one of the bottom surface and the two side surfaces. When the end surface of the groove is semicircular, the inner wall of the groove is similar to the inner wall of a semi-cylinder, and at least one row of sterilization assemblies can be installed in parallel on the inner wall of the semi-cylinder.

[0077] In the embodiment of the present application, the sensing component 22 is, for example, a light-sensitive sensor, etc., which can be arranged between two adjacent ultraviolet lamps, such as Figure 6 As shown in the black filled circle.

[0078] With this solution, the sterilization component includes a plurality of ultraviolet lamps spaced apart in the extending direction of the groove, and the sensing component includes a photosensitive sensor arranged in the extending direction of the groove, which facilitates the arrangement of the sterilization component and the sensing component.

[0079] Optionally, in the above embodiment, at least two ultraviolet lamps spaced apart in the second direction are arranged at equal intervals, and when the sensing component includes at least two photosensors arranged in the first direction, the at least two photosensors are asymmetrically arranged in the second direction.

[0080] Please refer to Figure 6Multiple ultraviolet lamps 231 are evenly spaced along the groove's extension direction. The number of ultraviolet lamps 231 is related to the spacing between adjacent ultraviolet lamps 231 and the length of the roller brush 122. The smaller the spacing and the longer the length, the more ultraviolet lamps 231 are needed; the larger the spacing and the shorter the length, the fewer ultraviolet lamps 231 are needed. By evenly arranging the ultraviolet lamps 231, the ultraviolet lamps 231 illuminate the entire axial direction of the roller brush 122. As the roller brush 122 rotates, the entire surface of the roller brush 122 is sterilized without missing any spots.

[0081] Furthermore, when the sensing assembly 22 includes at least two photosensors 221, the at least two photosensors 221 do not need to be evenly spaced in the direction in which the groove extends. This allows the photosensors 221 to be flexibly positioned at any location in the direction in which the groove extends. Of course, they can also be evenly spaced in the direction in which the groove extends, and this is not a limitation of the present embodiment.

[0082] Optionally, in the above embodiment, the sterilization component 23 also includes a lamp board 232 and a protective plate 233, the lamp board 232 is located below the groove and fixed at the bottom of the groove, the at least two ultraviolet lamps 231 are evenly distributed on the lamp board 332, and the protective plate 233 and the groove cooperate to form a cavity for protecting the at least two ultraviolet lamps 231.

[0083] For example, please refer to Figure 7 , Figure 7 This is a schematic diagram of the structure of the sterilization component on the tray of the cleaning system provided in the embodiment of the present application. Figure 7 The protective plate 233 covers the groove to form a sealed cavity. The lamp board 232 is located within the sealed cavity, and the ultraviolet lamp 231 is mounted on the lamp board. By placing the ultraviolet lamp 231 within the sealed cavity, residual liquid on the roller brush 122 can be prevented from entering the ultraviolet lamp 231, thereby increasing the service life of the ultraviolet lamp 231. The protective plate 233 is made of a transparent material, for example, to allow light to pass through.

[0084] By adopting this solution, by setting up protective plates, lamp plates, etc., it is ensured that the ultraviolet lamp can be fixed in the groove and is kept in a dry state, thereby achieving the purpose of extending the service life of the ultraviolet lamp.

[0085] Optionally, in the above embodiment, the outer end surface of the protective plate 233 is flush with the inner wall of the accommodating area 24. In other words, the protective plate 233 cooperates with the groove to make the inner wall of the accommodating area 24 smooth. The protective plate 233 and the groove may be fixed together by a sealant, etc., which is not limited in this embodiment.

[0086] With this solution, the outer end face of the protective plate is flush with the inner wall of the accommodating area. After the cleaning equipment 100 is placed on the tray 200, no water will accumulate in the groove, and the sterilization effect of the sterilization component 23 will not be affected by the accumulated water on the outer wall of the protective plate 233.

[0087] Optionally, in the above embodiment, the sterilization component 23 is fixedly disposed in the groove, which can ensure that the angle and irradiation range of the ultraviolet light emitted by the sterilization component 23 are within a stable range, thereby improving the sterilization effect.

[0088] In the above embodiment, when the sterilization assembly 23 is used to sterilize the roller brush, the ultraviolet radiation emitted by the ultraviolet lamp is relatively strong, which can eliminate a large number of bacteria. However, if the ultraviolet radiation is irradiated to the user, a large amount of bacteria will be generated. Therefore, in the embodiment of the present application, sterilization is only performed when the roller brush 122 is installed. In addition, when the roller brush is installed, in order to prevent ultraviolet radiation leakage, it is necessary to ensure that the ultraviolet lamp 231 is placed in a suitable position to ensure that the ultraviolet radiation emitted by the ultraviolet lamp 231 can only irradiate the interior of the cleaning device and not the exterior.

[0089] In order to ensure that the ultraviolet rays can only irradiate the roller brush 122 inside the cleaning equipment, optionally, the above-mentioned sterilization component 23 also includes a hollow anti-leakage device 234, the first end of the anti-leakage device 234 is arranged at the bottom of the groove, and each of the ultraviolet lamps is arranged at the first end of the anti-leakage device 234, and the second end of the anti-leakage device 234 is a transparent cover, which forms the outer end face of the groove, and the anti-leakage device 234 is used to guide the ultraviolet rays emitted by the ultraviolet lamp 231 to the roller brush 122.

[0090] Please refer to Figure 8 , Figure 8 This is a side view of the sterilization component of the tray of the cleaning system provided in the embodiment of the present application. Figure 8 The sterilization assembly 23 also includes a hollow anti-leakage device 234. Each UV lamp 231 is mounted on the first end of the anti-leakage device 234. The sidewalls of the anti-leakage device 234 are made of an opaque material to prevent UV light from leaking out and causing harm to the human body. The second end of the anti-leakage device 234 forms the outer end surface of the groove, such as the aforementioned protective plate 233.

[0091] Optionally, in the above embodiment, the sterilization component 23 includes at least two ultraviolet lamps 231 , and the light emitting angle of each ultraviolet lamp 231 is configured so that the light irradiated outside the surface of the roller brush 122 is blocked by the roller brush cover 123 or the accommodating area 24 .

[0092] For example, in addition to adjusting the deployment position of the ultraviolet lamp 231 and assuming the anti-leakage device 234 as described above, the ultraviolet light leakage can also be prevented by adjusting the light-emitting angle of the ultraviolet lamp 231. In this method, the ultraviolet lamp 231 is, for example, a ultraviolet lamp with a relatively large light-emitting angle, such as 125 degrees, 140 degrees, 130 degrees, etc., which is not limited in the embodiments of the present application. During the sterilization process, most of the ultraviolet light is irradiated on the surface of the roller brush 122, and the rest is blocked by the accommodating area 24, the roller brush cover 123, etc., thereby preventing ultraviolet light leakage and preventing harm to the human body.

[0093] Although the above Figure 3 、 Figure 5D In the embodiment, the sterilization component includes a column of ultraviolet lamps 231. However, the embodiment of the present application is not limited thereto, and in other optional implementations, the sterilization component 23 includes at least two ultraviolet lamps 231, and the at least two ultraviolet lamps 231 are linearly arranged to form at least two columns of ultraviolet lamps, each column of ultraviolet lamps extending along the extension direction of the groove.

[0094] For example, at least two rows of ultraviolet lamps extend along the groove direction and are parallel to each other. During the sterilization process, compared with only one row of ultraviolet lamps, at least two rows of ultraviolet lamps can illuminate more surfaces of the roller brush 122, thereby improving sterilization efficiency and shortening sterilization time.

[0095] Optionally, in the above embodiment, the at least two columns of ultraviolet lamps include a first queue and a second queue, and the ultraviolet lamps located in the first queue and the ultraviolet lamps located in the second queue are arranged opposite each other or staggered at a predetermined distance from each other.

[0096] For example, the end face of the groove is rectangular. The row of UV lamps at the bottom of the groove is the first row, and the UV lamps on the side walls of the groove are the second row. The UV lamps in the first row are evenly spaced, with a certain interval between each pair. The UV lamps in the second row correspond to the intervals in the first row. This allows the UV lamps to illuminate a wider range and achieve a better sterilization effect.

[0097] Based on the above cleaning system, the present application embodiment also provides a roller brush installation identification method, for example, please refer to Figure 9 . Figure 9 Flowchart of a roller brush installation identification method provided by an embodiment of the present application. This embodiment is applied to a tray of a cleaning system, wherein the cleaning system includes a cleaning device and a tray. The method includes:

[0098] 901. When the cleaning device is placed on the tray, the light intensity of the light emitted by the light source is captured by the sensing component on the tray to obtain a resistance value corresponding to the light intensity.

[0099] 902. Determine whether the resistance is greater than a preset resistance. If the resistance is greater than the preset resistance, execute step 903; if the resistance is less than or equal to the preset resistance, execute step 904.

[0100] The preset resistance value is, for example, any resistance value within a resistance range, where the resistance values ​​within the resistance range are the resistance values ​​of the sensing component under different natural light environments.

[0101] 903. When the resistance value is greater than a preset resistance value, it is determined that the roller brush is installed on the floor brush body, the cleaning device includes a floor brush assembly, the floor brush assembly includes the floor brush body and a roller brush detachably mounted relative to the floor brush body, and the light source is disposed on the floor brush body;

[0102] 904. When the resistance value is less than or equal to the preset resistance value, it is determined that the roller brush is not installed on the floor brush body.

[0103] For details, please refer to the above-mentioned cleaning system, which will not be described here.

[0104] The roller brush installation identification method provided in the embodiment of the present application is applied to the tray of the cleaning device. When the cleaning device is placed on the tray, the sensor component on the tray is used to capture the light intensity emitted by the light source to obtain the resistance value corresponding to the light intensity. When the resistance value is greater than the preset resistance value, it is determined that the roller brush is installed on the floor brush body. The cleaning device includes a floor brush assembly, which includes a floor brush body and a roller brush that is detachably mounted relative to the floor brush body. The light source is set on the floor brush body. When the resistance value is less than or equal to the preset resistance value, it is determined that the roller brush is not installed on the floor brush body.

[0105] With this solution, the light intensity is sensed by the sensing component to determine whether the roller brush is installed, which has high accuracy and fast speed.

[0106] Optionally, in the above embodiment, the illumination light emitted by the light source on the cleaning device passes through the light guide plate on the roller brush cover to generate a first light path and a second light path. The first light path is parallel to a first direction, and the angle between the second light path and the first direction is configured to guide the second light path toward the accommodating area of ​​the tray, where the first direction is the front-to-back direction of the cleaning device. The tray utilizes a sensing component on the tray to capture the second light path from the light emitted by the light source, and determines the resistance value based on the light intensity of the second light path, thereby determining whether the roller brush is installed.

[0107] For details, please refer to the description of the cleaning system above, which will not be repeated here.

[0108] By adopting this solution, the bright light generated by the light source generates the first light and the second light after passing through the light guide plate. The second light is directed towards the accommodating area, and the sensing component of the tray senses the second light, so that the sensing component can accurately detect the change in light intensity, and then the tray can accurately identify whether the roller brush is installed, thereby improving the accuracy of roller brush installation identification.

[0109] Optionally, in the above embodiment, when the tray determines that the resistance of the sensing component is greater than the preset resistance, it is determined that the roller brush is installed on the floor brush body, and after the cleaning device completes self-cleaning, the sterilization component on the tray is controlled to turn on to sterilize the roller brush.

[0110] Typically, the roller brush of a cleaning device becomes dirty after use. After the user places the cleaning device on the tray, the tray first detects whether the roller brush is installed. If the roller brush is installed on the floor brush body, it undergoes a self-cleaning process. After the self-cleaning process is complete, the roller brush enters the cleaning state, at which point the tray activates the sterilization component to disinfect the roller brush. This solution allows the tray to detect whether the roller brush is installed before the cleaning device self-cleans, preventing the cleaning device from performing self-cleaning and sterilization without the roller brush installed.

[0111] In addition, after the user places the cleaning device on the tray, the tray can first self-clean the roller brush. After the self-cleaning is completed, it will detect whether the roller brush is installed. If the roller brush is installed on the floor brush body, the tray will activate the sterilization component to disinfect the roller brush.

[0112] Below, in combination with specific application scenarios, taking the cleaning equipment as a floor cleaning machine as an example, the technical solution provided in the embodiment of the present application is described in detail to help understanding.

[0113] Application Scenario 1

[0114] The cleaning system includes a cleaning device 100 and a tray 200. The cleaning device 100 comprises a main body 11 and a floor brush assembly 12 rotatably connected to the main body 11. The main body 11 is provided with functional components such as a clean water bucket and a dirty water bucket. The floor brush assembly 12 is used to clean work surfaces, etc. The floor brush assembly 12 includes a floor brush body 121, a roller brush 122, a roller brush cover 123, and a roller 124. The tray 200 includes a tray body 21, a sensor assembly 22, a sterilization assembly 23, a processor, a storage area 24, a charging assembly 25, a limiter 26, and a container 27.

[0115] After the user uses the cleaning device 100, the cleaning device 100 is placed on the tray 200. The cleaning device 100 and the tray 200 cooperate with each other, the roller brush 122 is located in the accommodating area 24 of the tray 200, and the rolling wheel 124 is located in the limiting part 26 on the tray 200. Through various limiting cooperation, the cleaning device 100 is ensured to be placed stably to avoid the phenomenon of the cleaning device 100 tipping over.

[0116] After the cleaning device 100 is stably placed on the tray 200, the user can choose to manually turn it on or the cleaning system can automatically turn on the self-cleaning function. After the self-cleaning function is turned on, the light source 125 on the cleaning device 100 emits illumination light, and the duration is, for example, 1 second, 3 seconds, etc., which is not limited in this embodiment. The light source 125 emits illumination light and generates a first light path 31 and a second light path 32 after passing through the light guide plate 126. The sensing component 22 on the tray 200 captures the second light path and inputs the corresponding resistance value to the processor according to the light intensity. The processor determines whether the resistance value is greater than the preset resistance value. When the resistance value is greater than the preset resistance value, it is determined that the roller brush is not installed, self-cleaning is interrupted, and a prompt message is issued to remind the user that the roller brush is not installed. For example, the cleaning device outputs prompt information through voice, flashing lights, sending messages to electronic devices that have installed the application (application, APP) of the cleaning device, etc.

[0117] When the resistance value is less than or equal to the preset resistance value, the tray determines that the roller brush has been installed on the floor brush body and continues self-cleaning. At this time, the water pump located in the body 11 controls the clean water bucket to provide clean water or cleaning liquid to the roller brush 122, and the roller brush 122 rotates and cleans under the control of the motor. At the same time, the sewage generated during the rotation of the roller brush 122 enters the accommodating area 24 of the tray 200. The motor inside the cleaning device 100 provides negative pressure to the sewage suction port on the floor brush assembly, and the sewage on the accommodating area 24 is sucked in through the sewage suction port. The sucked sewage enters the sewage suction channel through the sewage suction port. Repeat the above steps until the roller brush 122 is clean.

[0118] After the dirtiness value of the roller brush 122 is lower than the threshold or the self-cleaning time is longer than the preset time, the cleaning device 100 stops supplying water to the roller brush 122, the roller brush 122 continues to rotate, and the motor in the cleaning device 100 continues to work to air-dry the roller brush. At the same time, the sterilization component 23 is turned on, and the ultraviolet rays generated by the sterilization component are irradiated to part of the surface of the roller brush 122 to sterilize the roller brush 122. As the roller brush 122 rotates, the ultraviolet rays can irradiate the entire outer surface of the roller brush 122, thereby sterilizing the roller brush 122 comprehensively and thoroughly, preventing the roller brush 122 from breeding bacteria and producing odors. After a period of time, the tray closes the sterilization component and the self-cleaning task ends.

[0119] Application Scenario 2

[0120] The difference between this scenario and the above-mentioned application scenario 1 is that in this scenario, the cleaning system first performs self-cleaning on the cleaning device, and then determines whether the roller brush is installed.

[0121] Specifically, after the cleaning device 100 is stably placed on the tray 200, the user can choose to manually turn on the self-cleaning function or the cleaning system can automatically turn on the self-cleaning function. After turning on the self-cleaning function, the water pump located in the body 11 controls the clean water bucket to provide clean water or cleaning liquid to the roller brush 122, and the roller brush 122 rotates and cleans under the control of the motor. At the same time, the sewage generated during the rotation of the roller brush 122 enters the accommodating area 24 of the tray 200, and the motor inside the cleaning device 100 provides negative pressure to the sewage suction port on the floor brush assembly, and the sewage on the accommodating area 24 is sucked in through the sewage suction port. The sucked sewage enters the sewage suction channel through the sewage suction port. Repeat the above steps until the roller brush 122 is clean.

[0122] Afterward, light source 125 emits illumination light for a duration of, for example, 1 second or 3 seconds, though this embodiment is not limiting. The illumination light emitted by light source 125 passes through light guide plate 126, generating first light 31 and second light 32. Sensor assembly 22 on tray 200 captures the second light and inputs a corresponding resistance value based on the light intensity to the processor. The processor then determines whether the resistance value is greater than a preset resistance value. If the resistance value is greater than the preset resistance value, it is determined that the roller brush is not installed, self-cleaning is interrupted, and a prompt message is issued to inform the user that the roller brush is not installed.

[0123] When the resistance value is less than or equal to a preset value, the tray determines that the roller brush is installed on the floor brush body and activates the sterilization component 23. The sterilization component generates ultraviolet light that partially irradiates the surface of the roller brush 122, sterilizing it. As the roller brush 122 rotates, the ultraviolet light reaches the entire outer surface of the roller brush 122, thus completely sterilizing it and preventing bacteria and odors. After a period of time, the tray deactivates the sterilization component, and the self-cleaning task ends.

[0124] The present application also provides a tray, comprising a tray body, a sensing component, a sterilization component, and a processor, wherein the tray body has a receiving area for accommodating the roller brush, the bottom of the receiving area has a groove, and the sensing component and the sterilization component are arranged in the groove;

[0125] When the cleaning device is placed on the tray, the sensing component is configured to capture the light intensity emitted by the light source on the cleaning device and input the light intensity to the processor. The processor is configured to determine whether the roller brush is installed on the floor brush body based on the light intensity, and then control the switch of the sterilization component based on the recognition result.

[0126] For details, please refer to the description of the cleaning system above, which will not be repeated here.
