[0051] To make the objectives, technical solutions, and advantages of this application clearer, the following describes this application in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this application and are not intended to limit this application.

[0052] It should be noted that the terms "first," "second," etc., used in this application can be used to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish the first element from the second element. The terms "comprising" and "having," and any variations thereof, used in this application are intended to cover non-exclusive inclusion. The term "multiple" as used in this application refers to two or more. The term "and / or" as used in this application refers to one of the solutions, or any combination of multiple solutions.

[0053] In the process of using existing cleaning equipment, the type of roller brush is often changed manually by identifying the current cleaning environment, thus requiring manual replacement of the corresponding type of roller brush for cleaning. The entire process requires manual operation, which is not very convenient.

[0054] In order to solve the above problems, this application proposes a method for replacing the roller brush assembly of a cleaning equipment.

[0055] The method for replacing the roller brush assembly of a cleaning equipment provided in the embodiments of this application can be applied to cleaning equipment, such as sweeping robots, mopping robots, floor scrubbers, etc.

[0056] In an exemplary embodiment, FIG1 provides an application scenario diagram of a method for replacing the roller brush assembly of a cleaning equipment, which is a structural diagram of the roller brush mechanism in the cleaning equipment. The cleaning equipment includes a second housing 12, a limiting component 13, and a roller brush assembly. A roller brush assembly is housed within the mounting cavity of the cleaning device; the roller brush assembly includes a first housing 11, a roller brush assembly connector connected to the first housing 11, and a roller brush connected to the roller brush assembly connector; wherein, a limiting component 13 is used to rotate to lock or unlock the first housing 11 and the second housing 12.

[0057] Understandably, when the roller brush assembly is not assembled or locked with other structures in the cleaning device, locking and unlocking between the first housing 11 and the second housing 12 of the cleaning device allows the roller brush assembly to be connected to the cleaning device.Assembly and Separation. During the automatic replacement of the roller brush assembly in the base station, the currently used roller brush assembly (hereinafter referred to as the used roller brush assembly) is separated from the second housing 12 for detachment, and the required roller brush assembly (hereinafter referred to as the spare roller brush assembly) is installed to complete the replacement of the roller brush assembly. The used roller brush assembly and the spare roller brush assembly are collectively referred to as roller brush assemblies. The names "used roller brush assembly" and "spare roller brush assembly" are used only to better distinguish between the roller brush assembly to be replaced and the one being replaced. The same roller brush assembly body may change from a used roller brush assembly to a spare roller brush assembly, or vice versa, under different circumstances.

[0058] Optionally, the limiting component 13 can be on the first housing 11 or the second housing 12, or simultaneously on both the first housing 11 and the second housing 12; no limitation is made here. Similarly, optionally, when the used roller brush assembly detaches, the limiting component 13 can be limited to the first housing 11 and detach along with the used roller brush assembly; or it can be limited to the second housing 12 and not detach along with the used roller brush assembly. The rotation of the limiting component can be achieved by driving it with its own drive device or by having the limiting component rotated by a structure in the base station.

[0059] The replacement process of the roller brush component of the cleaning equipment includes the following two schemes:

[0060] Scheme 1, as shown in Figure 2, includes the following steps S101 to S102.

[0061] Step S101: Obtain relevant parameters of the working surface. The relevant parameters include at least one of physical characteristic parameters, the number of contaminants, and the type of contaminants.

[0062] Understandably, the cleaning equipment performs cleaning work on the working surface. The material of the working surface can be glass, blanket, wood, mixed material, ceramic, etc.; the smoothness of the working surface varies, and it can be uneven, smooth, rough, etc. In addition to the different working surfaces, the contaminants on the working surface are also divided into different categories. For example, the contaminant categories can be solid, liquid, mixed, etc. Solid contaminants include long / short hair, particulate matter, etc. Liquid contaminants include oil, grease, mucus, water, etc. Among them, the physical characteristic parameters include at least one of the following: material of the working surface, surface flatness, roughness, etc.

[0063] Step S102: When the target roller brush component category and the category of the roller brush component used are different, the cleaning equipment is moved to the base station and located in the roller brush replacement area of ​​the base station, and the limiting component is controlled to rotate to perform the operation of replacing the roller brush component used with the roller brush component corresponding to the target roller brush component category. The target roller brush component category is determined based on relevant parameters.

[0064] It can be understood that the main body that determines the target roller brush component category based on the relevant parameters of the current working surface can be the cleaning equipment or other equipment. Optionally, if the main body is other equipment, the other equipment will obtain the relevant parameters of the working surface, determine the target roller brush component category based on the relevant parameters, and then send the target roller brush component category to the cleaning equipment. Its specification 4 / 12 page 7In CN 121465472 A, the cleaning equipment is located in the roller brush replacement area, that is, the roller brush assembly is located in the roller brush replacement area. The process of replacing the roller brush assembly with the roller brush assembly corresponding to the target roller brush assembly category is an automatic operation process of the cleaning equipment and the base station, which does not require manual operation.

[0065] Optionally, when the working surface changes, it is determined whether to replace the roller brush according to the obtained new target roller brush assembly category. The factors for determining the change of the working surface include at least one of the following: change of the working surface, change of contaminants on the working surface, etc. Change of the working surface includes at least one of the following: change of the working surface category, change of roughness, change of working surface flatness, etc. Change of contaminants includes at least one of the following: contaminants in different locations, contaminant category, etc.

[0066] Scheme 2, as shown in Figure 3, includes the following steps S103.

[0067] In step S103, when a roller brush replacement instruction is obtained, the cleaning device is moved to the base station and located in the roller brush replacement area of ​​the base station. The roller brush replacement instruction includes the target roller brush component category. The limit component is controlled to rotate to perform the operation of replacing the roller brush component with the roller brush component corresponding to the target roller brush component category.

[0068] Understandably, in some cases, a roller brush replacement instruction can be sent to the cleaning device in different ways (e.g., the user operates through a mobile terminal or by touching the cleaning device). The cleaning device replaces the roller brush component according to the obtained roller brush replacement instruction, which can meet different user needs.

[0069] It should be noted that the cleaning device can execute either of the above two schemes, or both of the above schemes. Optionally, when executing the two schemes, there are two situations: execution at the same time period and execution at different time periods. When a roller brush replacement instruction is obtained at the same time, and it is determined that the target roller brush component category is different from the category of the roller brush component used, but neither scheme has been started or the execution time of either scheme is less than the preset execution time threshold, the scheme with higher priority can be executed according to the preset priority. If any scheme is currently being executed and its execution duration is greater than or equal to a preset execution duration threshold, then the currently executed scheme will be completed before determining whether to execute another scheme. Optionally, it is also possible to start executing another scheme directly regardless of the current state.

[0070] In addition, during the replacement of the roller brush assembly in the above two schemes, the rotation of the limiting component is controlled to unlock or lock the first housing of the roller brush assembly with the second housing of the cleaning device. Optionally, when the roller brush assembly is unlocked from the cleaning device, the roller brush assembly is directly detached; when the roller brush assembly is locked from the cleaning device, the roller brush assembly is installed and fixed on the cleaning device.

[0071] Optionally, the rotation of the limiting component can be controlled by the cleaning device itself, or it can be caused to rotate by external force pressing or rotating, etc., without limitation.

[0072] In this embodiment, there is no need for manual identification of whether the type of roller brush component needs to be replaced in the current environment, nor is there a need for manual replacement. The replacement process is automated, greatly improving the efficiency and intelligence of the equipment's automated operation. By autonomously judging and executing the replacement process of the roller brush component type through preset logic, the consistency and adaptability of the cleaning effect are effectively guaranteed, while reducing the operational errors and time costs caused by manual intervention. The system can flexibly select the execution strategy according to the actual use scenario to ensure the continuity of tasks and the stability of equipment operation, meeting the needs of efficient operation in complex environments.

[0073] In some embodiments, during the replacement of the roller brush component, the roller brush component includes a first connecting part; the cleaning equipment includes a driving body, and the driving body includes a second connecting part; the first connecting part is connected to the second connecting part. The method also includes:

[0074] Detachment method one:

[0075] When the roller brush component is located in the roller brush replacement area of ​​the base station, the first connecting part and the second connecting part of the roller brush component are separated.

[0076] Understandably, in order to make the roller brush assembly more stable during use, it is also necessary to fix the roller brush assembly to the drive body in another way. For example, the two ends of the roller brush assembly shaft can be connected to the drive body so that the roller brush assembly will not loosen or fall off during high-speed operation, ensuring the continuity and reliability of the cleaning work. Therefore, the above-mentioned stabilization effect can be achieved by connecting the first connecting part of the roller brush assembly and the second connecting part of the drive body. The drive body can be at least one of electromagnetic drive (e.g., electromagnetic direct drive), linear-to-rotary mechanism, pneumatic / hydraulic drive, and elastic energy storage drive.

[0077] Of course, correspondingly, in the process of replacing the roller brush assembly, in addition to controlling the rotation of the limiting component to unlock the roller brush assembly from the cleaning equipment, it is also necessary to separate the roller brush assembly from the drive body. That is, the roller brush assembly will only fall off when the first housing and the second housing are unlocked and the first connecting part of the roller brush assembly is separated from the second connecting part of the drive body.

[0078] In this embodiment, the base station opens the closed opening of the roller brush replacement area before detachment. When it is determined that the roller brush assembly of the cleaning device is located in the roller brush replacement area, the cleaning device controls the first connecting part of the roller brush assembly to separate from the second connecting part of the drive body. The cleaning device determines that the roller brush assembly is located in the roller brush replacement area by: acquiring location information and / or image information through sensors / switches, etc., and then determining whether the roller brush assembly is located in the roller brush replacement area based on the location information and / or image information.

[0079] Detachment method two:

[0080] When the roller brush assembly is located in the roller brush replacement area of ​​the base station, upon acquiring detachment information, the first connecting part of the roller brush assembly is controlled to separate from the second connecting part of the drive body.

[0081] Optionally, when the base station opens the closed opening at the brush replacement area, it generates detachment information and transmits it to the cleaning device. The cleaning device then uses the acquired detachment information to separate the brush assembly from the first connecting part. The brush assembly can only fall into the receiving cavity in the base station base after the closed opening is opened.

[0082] Optionally, other devices may trigger the generation of detachment information, and the cleaning device can use this information to control the separation of the brush assembly from the first connecting part.

[0083] It should be noted that the order of the two processes—unlocking the first housing from the second housing and separating the first connecting part from the second connecting part—is not limited here; either process can occur before the other, or both processes can occur simultaneously.

[0084] In some embodiments, referring to Figures 4 and 5, the brush assembly 21 includes a brush 211, a shaft 212, and a drive unit 213. The brush 211 is sleeved on the shaft 212, and the shaft 212 is connected to the first connecting part 22. For example, the shaft 212 is provided with a first shaft hole 2121, and the connecting part 22 includes a first connecting shaft 223. The first connecting shaft 223 is inserted into the first shaft hole 2121 and connected by a bearing assembly. This not only ensures stable transmission between the shaft 212 and the first connecting part 22, but also effectively reduces friction, reduces energy loss, and extends the service life of the components.

[0085] At the same time, the connecting part 22 also includes a second connecting shaft 225. The second connecting shaft 225 is provided with a second shaft hole 2251, and the first connecting shaft 223 is inserted into the second shaft hole 2251. This double-insertion connection structure further enhances the connection strength and stability between the various parts of the roller brush assembly 21, ensuring that there will be no loosening or falling off during high-speed operation, and ensuring the continuity and reliability of the cleaning work.

[0086] It should be noted that the number of roller brushes 211 and the number of shafts 212 can be flexibly set according to actual usage requirements. For example, in simple cleaning scenarios, a single roller brush 211 and a shaft 212 can be used. The roller brush 211 is fitted onto the shaft 212, which meets basic cleaning requirements. This setup is simple in structure, low in cost, and suitable for small areas or places where cleaning efficiency requirements are not high. When higher cleaning efficiency is needed or to handle complex cleaning environments, two roller brushes 211 and two shafts 212 can be used, with each roller brush 211 and shaft 212 installed in a one-to-one correspondence. In this case, the shafts 212 have two movement options: one is separate movement, where each shaft 212 is independently controlled and can be adjusted according to the cleaning needs of different areas, achieving precise cleaning of complex floors. The other is to use a coupling to connect the two shafts 212 together, achieving synchronous movement. This synchronous movement ensures that the two roller brushes 211 rotate at the same speed and direction, creating a larger...The cleaning area is increased, improving cleaning efficiency, and is especially suitable for cleaning large areas of flat ground.

[0087] The drive unit 213 includes a drive body 2131 and a second connecting part 2132. The drive body 2131 is connected to the second connecting part 2132, and the second connecting part 2132 is detachably connected to the first connecting part 22, making the installation, disassembly and maintenance of the roller brush assembly 21 more convenient and improving the maintainability of the equipment.

[0088] The drive body 2131 is, for example, a drive motor. The number of drive motors can be adjusted according to the setting of the shaft 212 or the driving requirements. For example, when there are two shafts 212 and they need to move separately, each can be connected to a drive motor to achieve independent driving of the two shafts 212, and to accurately control according to the working state of different roller brushes 211 to meet diverse cleaning needs.

[0089] The drive body 2131 is configured to drive the second connecting part 2132 to rotate relative to the first connecting part 22, thereby realizing the assembly or separation of the second connecting part 2132 and the first connecting part 22. For example, the second connecting part 2132 is provided with a connecting screw hole 21321, and the first connecting part 22 is provided with a connecting screw 224. The connecting screw 224 is threadedly connected to the connecting screw hole 21321, which gives it the advantages of firm connection and convenient disassembly, and can ensure that there will be no loosening during the driving process.

[0090] In actual operation, the connection and disassembly can be automated by using a drive motor. For example, when the drive motor rotates forward, the drive shaft of the drive motor drives the second connecting part 2132 to rotate, so that the connecting screw hole 21321 is gradually screwed onto the connecting screw 224, realizing the tight assembly of the second connecting part 2132 and the first connecting part 22; when the drive motor rotates in reverse, the drive shaft of the drive motor drives the second connecting part 2132 to rotate in the opposite direction, so that the connecting screw hole 21321 is disengaged from the connecting screw 224, completing the separation of the second connecting part 2132 and the first connecting part 22. In the assembled state, when the drive shaft of the drive motor rotates, it can drive the second connecting part 2132 to rotate. The second connecting part 2132 transmits the driving force to the first connecting part 22, causing it to rotate synchronously. The first connecting part 22 drives the roller brush 211 to rotate through the shaft 212, thereby cleaning the ground.

[0091] In order to further optimize the working performance of the drive part 213, a spring 2133 is sleeved on the drive shaft of the drive motor. The two ends of the spring 2133 abut against the second connecting part 2132 and the housing of the drive motor, respectively. On the one hand, the spring 2133 can provide a certain preload, making the connection between the second connecting part 2132 and the first connecting part 22 tighter, reducing the gap at the threaded connection, and improving the stability and reliability of the transmission; on the other hand, when the drive motor drives the second connecting part 2132 to rotate for assembly or disassembly operations, the spring can play a buffering role, reducing the impact force during the rotation process, protecting the components from damage, and extending the service life of the equipment.

[0092] The roller brush assembly 21 in this embodiment, through reasonable structural design, achieves stable connection between the roller brush 211 and the shaft 212, flexible quantity setting, and automated control and optimization of the drive unit 213, providing an efficient and reliable solution for ground cleaning work.

[0093] In some embodiments, during the replacement of the roller brush assembly, the method further includes:

[0094] In response to the operation of the base station triggering the roller brush detachment switch, controlling the first connecting part and the second connecting part of the roller brush assembly to separate.

[0095] Understandably, the tentacles on the base station touch the detachment switch on the cleaning device to generate detachment information, and the cleaning device separates the first connecting part and the second connecting part of the roller brush assembly according to the acquired detachment information.

[0096] In some embodiments, before replacing the roller brush assembly, the method further includes:

[0097] Sending a roller brush replacement request to the base station.

[0098] Understandably, the cleaning device needs to send a roller brush replacement request to the base station before the base station can perform the subsequent roller brush assembly replacement operation. Instruction manual 7 / 12 pages 10 CN 121465472 A

[0099] Of course, in other ways, the base station can actively identify whether the roller brush assembly needs to be replaced by recognizing the replacement request mark on the cleaning equipment. For example, by preset light color, preset symbol pattern, etc.

[0100] Optionally, the roller brush replacement request includes the target roller brush assembly category. This is because in some scenarios, the base station has multiple categories of spare roller brush assemblies, and it is necessary to select a spare roller brush assembly of the same category as the target roller brush assembly to replace it in the cleaning equipment.

[0101] The embodiments of this application effectively determine the target roller brush assembly category according to the relevant parameters of the working surface, and when the current target roller brush assembly category is different from the category of the currently used roller brush assembly, it automatically enters the base station to replace the roller brush assembly corresponding to the target roller brush assembly category, without the need for manual identification and manual operation replacement throughout the process.

[0102] Some embodiments of this application also propose a cleaning equipment, which includes:

[0103] at least one sensor for detecting relevant parameters of the working surface, the relevant parameters including at least one of physical characteristic parameters, pollutant quantity and pollutant category.

[0104] A processor is configured to execute the steps of the method for replacing the roller brush assembly in any of the above-described cleaning devices.

[0105] The sensor may be one of a pressure sensor, an acoustic sensor, and an optical sensor (laser rangefinder, vision sensor). The vision sensor may be a monocular vision sensor, a binocular vision sensor, etc. Optionally, an AI module may be used to assist sensor recognition.

[0106] In some embodiments, the roller brush assembly further includes a first connecting portion; the device further includes:

[0107] a second connecting portion;

[0108] a driving body;

[0109] The controller is used to control the operation of the drive body to separate the first connecting part of the roller brush assembly from the second connecting part when a detachment information is received; it is also used to control the operation of the drive body to assemble the second connecting part with the first connecting part of the spare roller brush assembly.

[0110] Understandably, the detachment information, as described above, can be sent by a base station or can be triggered by a touch or other means. Taking the drive body as an example, the drive body rotates in a first direction to separate the first connecting part of the roller brush assembly from the second connecting part of the drive body, and rotates in a second direction to assemble the first connecting part of the roller brush assembly with the second connecting part of the drive body. The first direction and the second direction are opposite.

[0111] Optionally, the two ends of the roller brush assembly are fixed in the mounting cavity of the cleaning device by means including but not limited to magnetic attraction or snap-fit.

[0112] Optionally, two motors can be used to simultaneously control the installation and detachment of the roller brush assembly, respectively set at both ends of the roller brush assembly.

[0113] In some embodiments, the cleaning device is provided with a mounting cavity; the cleaning device also includes a positioning detection component.

[0114] The controller is also configured to control the drive body to assemble the second connecting part with the first connecting part of the spare roller brush assembly when the positioning detection component detects that the spare roller brush assembly is located in the mounting cavity.

[0115] Understandably, when it is necessary to install the spare roller brush assembly into the mounting cavity of the cleaning equipment, the corresponding component will transport the spare roller brush assembly into the mounting cavity. However, at this time, the spare roller brush assembly is only in place but has not yet been assembled. Therefore, the cleaning equipment needs to perform fixed assembly. The cleaning equipment detects whether the current spare roller brush assembly is in place through the positioning detection component. When it is determined that it is in place, it controls the drive body to move so that its second connecting part is assembled with the first connecting part of the spare roller brush assembly.

[0116] Optionally, the positioning detection component may include at least one of a pressure sensor, an acoustic sensor, and an optical sensor (laser rangefinder sensor, vision sensor).

[0117] Optionally, the positioning detection component may generate a positioning signal through electronic structures such as circuit closure and switch closure, thereby determining that the spare roller brush assembly is in place based on the positioning information.

[0118] In some embodiments, the use of a roller brush assembly corresponds to a cleaning usage time. If the cleaning usage time exceeds a preset usage time threshold, the cleaning device is moved to the base station and located in the roller brush replacement area of ​​the base station to perform a roller brush assembly replacement operation.

[0119] Understandably, if the cleaning usage time of the roller brush assembly is too long, it indicates that the current roller brush is too dirty to support continued cleaning, and therefore a less dirty roller brush assembly needs to be replaced for cleaning.

[0120] Optionally, the roller brush replacement request includes a cleaning usage time; therefore, each spare roller brush assembly in the base station corresponds to...There is a cleaning usage time, and the spare roller brush assembly with the shortest cleaning usage time can be selected for replacement. Of course, it is also possible to select the spare roller brush assembly with the shortest cleaning usage time from all spare roller brush assemblies of the same category as the roller brush assembly used for replacement. Here, the cleaning usage time refers to the cumulative time used by the current roller brush assembly without cleaning. Optionally, when a roller brush assembly is cleaned, its corresponding cleaning usage time is reset to zero.

[0121] Optionally, each roller brush assembly has a service life and a usage time, and the usage time refers to the time period from the first time it was used after leaving the factory to the current time. When the usage time reaches the service life, a prompt message is generated.

[0122] In this embodiment of the application, the relevant parameters of the working surface are detected by the sensor, and the roller brush assembly is automatically determined based on the relevant parameters and the assembly parameters of the roller brush assembly (such as the cleaning usage time, service life, etc. mentioned above) to determine whether the roller brush assembly needs to be replaced. When the roller brush assembly needs to be replaced, it is automatically moved to the base station for replacement without manual operation, which saves manpower and improves the user experience. Users can also remotely control the cleaning equipment via mobile devices to replace it, ensuring a clean environment when they return home, even when they are not at home.

[0123] For ease of understanding, this application provides a detailed embodiment:

[0124] Step 1: During the cleaning process, the cleaning equipment acquires relevant parameters of the working surface. If the target roller brush component category determined according to the relevant parameters is different from the category of the currently used roller brush component, the cleaning equipment is moved to the base station.

[0125] Step 2: When the cleaning equipment is located in the roller brush replacement area of ​​the base station, a roller brush replacement request is sent to the base station.

[0126] Step 3: The base station controls the opening of the roller brush replacement area according to the roller brush replacement request. The base station moves the first support component inside the base, and touches / presses the detachment switch on the cleaning equipment through the protrusion on the first support component to generate a detachment signal; and the base station presses the limiting component with a tenon to separate the first housing of the roller brush component from the second housing of the cleaning equipment.

[0127] Step four: The cleaning equipment controls the drive body to rotate according to the detachment signal, causing the roller brush assembly to separate from the drive body; causing the roller brush assembly to detach onto the first support component.

[0128] Step five: The base station controls the first support component to move, so as to transfer the roller brush assembly to the second support component with a target support area, the target support area being the support area without a roller brush assembly.

[0129] Step six: The base station controls the unloaded movement of the first support component to transfer the spare roller brush assembly on the second support component.

[0130] Step seven: The base station controls the first support component carrying the spare roller brush assembly to move, so as to move the spare roller brush assembly into the mounting cavity of the cleaning equipment, and controls the rotation of the limiting component through mechanical coupling, so that the spare roller brush assembly...A housing is locked to the second housing of the cleaning device.

[0131] Step eight: When the cleaning device detects that the spare roller brush assembly is in place, it controls the drive body to rotate so that the spare roller brush assembly is assembled with the drive body to complete the installation of the spare roller brush set. Optionally, the spare roller brush set can be regarded as the roller brush set after it is detached from the second support assembly. Specification 9 / 12 pages 12 CN 121465472 A

[0134] Understandably, the user can perform a show / hide operation on the interface of the terminal device.
