Description

[0001] This disclosure claims the priority of the Chinese patent application filed with the China Patent Office on January 27, 2025, with application number 202510126171.7 and application name “A Self-Regulating Vacuum Cleaner”, the entire contents of which are incorporated by reference in this disclosure. Technical Field

[0002] The present disclosure relates to the technical field of cleaning equipment, and in particular to a method, device, equipment, medium and product for cleaning equipment. Background Art

[0003] In cleaning equipment, handling large particles and carpet cleaning has always been one of the important issues to be solved. Cleaning equipment is usually equipped with an opening and closing plate. The main function of this opening and closing plate is to adjust the gap between the floor brush and the cleaning surface so as to better handle particles of different sizes or perform carpet cleaning.

[0004] However, before using the cleaning device, the user needs to read the instructions or observe the floor brush parts to learn about the opening and closing plate and its opening parts. When using the cleaning device, the user needs to always pay attention to the condition of the cleaning surface and manually operate the opening parts at the brush head in time based on the condition of the cleaning surface, such as bending over to open the opening and closing plate. This operation is not only time-consuming, but also during the cleaning process, the particle size and the cleaning surface type may change. The user needs to adjust the position of the opening and closing plate according to different cleaning needs, which increases the user's burden in many aspects and further reduces the cleaning efficiency. Summary of the invention

[0005] The present disclosure provides a method, apparatus, equipment, medium and product for cleaning equipment, which ensures that an ideal cleaning effect can be achieved in various situations by automatically adjusting the position of an adjustment mechanism according to different types of dirt and / or the material of the cleaning surface. The process is automated, so users do not need to perform frequent manual operations, further improving cleaning efficiency.

[0006] In a first aspect, the present disclosure provides a method for a cleaning device, the cleaning device comprising a floor brush assembly, the floor brush assembly comprising an adjustment mechanism and an optical sensor, different positions of the adjustment mechanism correspond to different vacuum degrees inside the floor brush assembly, the method comprising:

[0007] Identifying the type of dirt on the cleaning surface and / or the material of the cleaning surface based on the optical information detected by the optical sensor; and

[0008] Controlling the adjustment mechanism to be in a target position based on the identified specific dirt type and / or the specific cleaning surface material, wherein the specific dirt type includes a first type of dirt, the first type of dirt is granular dirt having a diameter or height greater than or equal to a first threshold, and the specific cleaning surface material includes carpet;

[0009] Wherein, controlling the adjustment mechanism to be in the target position based on the identified specific dirt type and / or the specific material of the cleaning surface includes:

[0010] When it is identified that the specific type of dirt is the first type of dirt, the control adjustment mechanism is in the first position, and when it is identified that the material of the specific cleaning surface is carpet, the control adjustment mechanism is in the second position.

[0011] Thus, in the present disclosure, the cleaning device can automatically identify the specific type of dirt and / or the material of the specific cleaning surface based on the optical sensor, and then dynamically adjust the position of the adjustment mechanism based on the identified specific type of dirt and / or the material of the specific cleaning surface, without manual intervention, thereby greatly improving the cleaning efficiency. In particular, when dealing with large particles of dirt or carpets, the adjustment mechanism can be controlled to automatically adjust to a suitable position, thereby completing the cleaning task quickly and effectively. For example, for large particles of dirt, by changing the height of the adjustment structure relative to the cleaning surface, large particles of garbage are allowed to enter the floor brush assembly to avoid clogging; for carpets, the vacuum degree can be reduced to reduce resistance, making the floor brush assembly easier to push on the carpet, preventing the carpet fluff from being over-pulled or damaged, and also reducing the load on the floor brush motor, avoiding unnecessary high-load operation, thereby reducing the risk of overloading the floor brush motor, and helping to extend the service life of the floor brush motor.

[0012] Therefore, by identifying the specific type of dirt and the specific material of the cleaning surface, the cleaning equipment can adjust the cleaning strategy in a targeted manner. This precise processing method ensures that different types of dirt and cleaning surface materials can achieve ideal cleaning results.

[0013] Optionally, the optical information includes a signal waveform, wherein identifying a specific type of dirt and / or a specific material of the cleaning surface based on the optical information includes at least one of the following:

[0014] determining the type of the specific contamination as first type contamination based on the signal waveform, and

[0015] The material of the specific cleaning surface is determined to be carpet based on the signal waveform.

[0016] It is understandable that the signal waveform provides richer information, making the process of identifying the first type of dirt and carpet more accurate. For example, simply comparing the optical information provided by the optical sensor with the threshold value may cause misjudgment or even fail to distinguish the first type of dirt and carpet. By analyzing the signal waveform, misjudgment can be reduced and the reliability of identification can be improved. In addition, the signal waveform analysis can be performed quickly, so that the cleaning device can detect the first type of dirt or carpet in real time, and then select the appropriate cleaning method, thereby improving the cleaning effect while avoiding damage to the cleaning surface and extending the service life of the cleaning surface.

[0017] Optionally, the signal waveform is a waveform of an optical signal varying with time, wherein:

[0018] In the case where the signal waveform indicates a transient change, determining the type of the specific contamination is first type of contamination, and

[0019] When the signal waveform indicates a continuous change, it is determined that the material of the specific cleaning surface is carpet.

[0020] In this way, by analyzing the instantaneous change characteristics and continuous changes of the waveform, the cleaning equipment can quickly and accurately identify the specific type of dirt on the cleaning surface and the specific material of the cleaning surface, thereby improving cleaning efficiency, and the cleaning equipment can analyze and respond to the signal waveform in real time, thereby ensuring that it can quickly adapt to environmental changes during the cleaning process and provide instant cleaning adjustments. In addition, by identifying special materials such as carpets, the cleaning equipment can select appropriate cleaning methods and avoid using cleaning strategies that may damage the cleaning surface, thereby extending the service life of the cleaning surface.

[0021] Optionally, the method further includes:

[0022] When the specific type of dirt is identified as the second type of dirt, the control adjustment mechanism is in the third position;

[0023] The second type of dirt is granular dirt with a diameter or height smaller than the first threshold value, and the height of the adjustment mechanism from the cleaning surface when the adjustment mechanism is in the third position is smaller than the height from the cleaning surface when the adjustment mechanism is in the first position.

[0024] Therefore, for particles of different sizes and heights, by changing the height of the adjustment mechanism from the cleaning surface, particles of different sizes and heights can be easily entered. The height of the adjustment mechanism from the cleaning surface is different, and the corresponding vacuum degree is different. For larger particles, the height of the adjustment mechanism from the cleaning surface is increased to avoid blockage; for fine dust, the suction force is increased to ensure thorough cleaning. In this way, through optimized settings for different types of dirt and intelligent adjustment of the suction force, it can be ensured that the ideal cleaning effect can be achieved in various situations, and unnecessary energy consumption can be avoided, thereby improving the energy efficiency of the cleaning equipment. In addition, the above-mentioned automatic adjustment mechanism also reduces the need for manual adjustment by the user, making the cleaning process smoother and more efficient, thereby improving the cleaning efficiency.

[0025] Optionally, the first threshold is a value between 1 mm and 10 mm.

[0026] Therefore, setting the first threshold as a range provides greater flexibility. By dynamically adjusting the threshold between 1mm and 10mm, the floor brush assembly can adapt to a variety of cleaning scenarios and thus can more effectively handle various types of dirt from fine dust to larger particles. This flexibility allows the floor brush assembly to automatically select the appropriate cleaning mode under different cleaning surface materials and dirt conditions, thereby increasing the scope of application.

[0027] Optionally, the method further includes:

[0028] When it is identified that the material of the specific cleaning surface is non-carpet, the control adjustment mechanism is in the fourth position;

[0029] Wherein, when the adjustment mechanism is in the second position, the height from the cleaning surface is greater than the height from the cleaning surface when the adjustment mechanism is in the fourth position.

[0030] Therefore, on non-carpets, the smaller gap between the adjustment mechanism and the cleaning surface enhances the suction force and improves the cleaning ability of dust and fine particles. On carpets, the larger gap between the adjustment mechanism and the cleaning surface can adjust the vacuum degree, reduce the resistance to the fluff, avoid overloading the floor brush motor, and improve the mobility of the floor brush assembly. In this way, by adjusting the position of the adjustment mechanism according to the identified cleaning surface material, it can provide ideal cleaning effects on different cleaning surface types. In addition, there is no need for the user to manually adjust the floor brush assembly. The cleaning equipment can automatically adjust the position of the adjustment mechanism according to the detected cleaning surface material, thereby improving ease of use and user experience.

[0031] Optionally, when it is identified that the specific dirt type is the first type of dirt, controlling the regulating mechanism to be in the first position includes:

[0032] When the specific type of soiling is identified as the first type of soiling, the first position of the adjustment mechanism is determined based on the diameter or height of the first type of soiling.

[0033] In this way, by dynamically adjusting the position of the adjusting mechanism according to the specific size of the dirt, it is ensured that the cleaning equipment can effectively handle particles of various sizes, thereby improving the cleaning effect. By optimizing the position of the adjusting mechanism, the risk of large particles of garbage getting stuck in the cleaning equipment can also be reduced, thereby ensuring the stable operation of the cleaning equipment. In addition, the above-mentioned automated size measurement and adjustment reduces the need for manual operation by the user, simplifies the operating process, improves user satisfaction, and makes the present disclosure applicable to handling dirt of various types and sizes, thereby increasing the breadth of application.

[0034] Optionally, an adjustment bin is provided at the front of the floor brush assembly, an adjustment mechanism is provided on the adjustment bin, a dust collection port is provided on the bottom surface of the adjustment bin, and the adjustment mechanism includes a stopper, which is configured to move relative to the cleaning surface to change the degree to which the dust collection port is blocked by the stopper;

[0035] Wherein, determining the first position of the adjustment mechanism based on the diameter or height of the first type of dirt includes: determining the height of the stopper relative to the cleaning surface based on the diameter or height of the first type of dirt.

[0036] In this way, the position of the stopper is accurately adjusted according to the diameter or height of the first type of dirt to adaptively control the opening degree of the dust collecting port, so that the cleaning equipment can optimize the opening size of the dust collecting port according to the specific size of the dirt, ensuring that the dirt is effectively removed, and precise adjustment can also reduce cleaning time and energy consumption, because the cleaning equipment can handle large particles of dirt more effectively, and also reduce the risk of large particles of garbage getting stuck in the cleaning equipment.

[0037] Optionally, the optical sensor includes a light emitter and a light receiver, at least part of the light emitted by the light emitter is received by the light receiver, and in the presence of a specific type of dirt and / or material of the cleaning surface, the light emitted by the light emitter is at least partially blocked, and the type of dirt on the cleaning surface and / or the material of the cleaning surface is identified at least partly based on the light received by the light receiver; the method further includes:

[0038] determining light intensity information or light energy information as optical information based on the light received by the light receiver;

[0039] When the light intensity information or the light energy information is less than or equal to the second threshold, the specific type of dirt is determined to be the first type of dirt.

[0040] Therefore, through the cooperation of the light emitter and the light receiver, the floor brush assembly can detect changes in light, and then determine changes in light intensity or light energy based on the light information received by the light receiver, so as to accurately identify whether the specific type of dirt is the first type of dirt. This accurate identification reduces the possibility of misjudgment and helps to optimize the cleaning strategy. In addition, the light emitter and light receiver can also monitor changes on the cleaning surface in real time and quickly identify different dirt conditions and material types.

[0041] Optionally, the method further includes:

[0042] When it is identified that the material of the specific cleaning surface is a carpet, determining the pile length of the carpet based on the optical information;

[0043] If the pile length of the carpet is greater than or equal to a third threshold, the control adjustment mechanism is in a fifth position;

[0044] If the pile length of the carpet is less than the third threshold, the control adjustment mechanism is in the sixth position;

[0045] Wherein, when the adjustment mechanism is in the fifth position, the height from the cleaning surface is greater than the height from the cleaning surface when the adjustment mechanism is in the sixth position.

[0046] In this way, on long-pile carpets, the adjustment mechanism has a larger gap from the cleaning surface to reduce resistance to the pile, prevent excessive wear and damage to carpet fibers, extend the service life of the carpet, and avoid overloading the floor brush motor, while improving the mobility of the floor brush assembly. On short-pile carpets, the adjustment mechanism has a smaller gap from the cleaning surface to enhance suction and improve the cleaning ability of dust and fine particles. In this way, by optically identifying the length of carpet pile and adjusting the position of the adjustment mechanism, ideal cleaning effects can be provided on different types of carpets. In addition, by appropriately adjusting the position of the adjustment mechanism, excessive loading of the floor brush motor on carpets with different pile lengths can also be avoided.

[0047] It should be noted that the user does not need to manually adjust the floor brush assembly. The floor brush assembly will automatically adjust the position of the adjustment mechanism according to the detected carpet pile length, thereby improving ease of use and user experience.

[0048] Optionally, the third threshold is a value between 1 mm and 10 mm.

[0049] Therefore, setting the third threshold as a range provides greater flexibility. By dynamically adjusting the threshold between 1 mm and 10 mm, it is ensured that the cleaning device can provide ideal cleaning effects on both long-pile and short-pile carpets and avoid the problem of excessive or insufficient adsorption. Moreover, by setting a reasonable third threshold, the cleaning device can more accurately identify the carpet type, thereby providing more effective cleaning on different carpets and improving application flexibility.

[0050] Optionally, the cleaning device further includes at least one of a current sensor for detecting current information of the floor brush motor, an electric power sensor for detecting electric power information of the floor brush motor, and a vacuum sensor for detecting vacuum information in the floor brush assembly, and the method further includes:

[0051] Identifying a special cleaning condition based on the optical information, wherein the special cleaning condition includes a specific type of dirt and / or a specific material of the cleaning surface; and

[0052] When a special cleaning condition is identified, it is determined whether the special cleaning condition is a specific type of dirt or a specific material of the cleaning surface based on comprehensive information, wherein the comprehensive information includes at least one of optical information, current information, electric power information, and vacuum degree information.

[0053] In this way, by combining information from multiple sensors, the cleaning equipment can more accurately identify special cleaning conditions and reduce misjudgments. This multi-sensor fusion design improves the intelligence level of the cleaning equipment, enabling it to adapt more flexibly to different cleaning scenarios. Without manual intervention by the user, the cleaning equipment can automatically identify the specific type of dirt and / or the material of the cleaning surface to adjust the position of the adjustment mechanism, thereby simplifying operation and improving user experience.

[0054] It is understandable that after accurately identifying the special cleaning conditions, the cleaning equipment can select the appropriate cleaning strategy to ensure the ideal cleaning effect.

[0055] Optionally, an adjustment bin is provided at the front of the floor brush assembly, an adjustment mechanism is provided on the adjustment bin, a dust collection port is provided on the bottom surface of the adjustment bin, a bin cover is provided at the upper portion of the adjustment bin, an air inlet is provided on the bin cover, the adjustment mechanism comprises a block and an air valve for blocking the air inlet, the block is configured to move relative to the cleaning surface to change the degree to which the dust collection port is blocked by the block, and the ventilation area of ​​the air inlet is changed by adjusting the air valve, wherein controlling the adjustment mechanism to be in the target position comprises:

[0056] When it is identified that the material of the specific cleaning surface is non-carpet and the type of the specific dirt is the first type of dirt, controlling the stopper to be in the first position to increase the height of the stopper relative to the cleaning surface;

[0057] When it is identified that the material of the specific cleaning surface is carpet, the stopper is controlled to be in the first position to increase the height of the stopper relative to the cleaning surface.

[0058] Detect at least one of the current information of the floor brush motor, the electric power information of the floor brush motor, and the vacuum degree information in the floor brush assembly,

[0059] determining whether the step of controlling the stopper to be in the first position causes the load of the floor brush motor or the vacuum degree in the floor brush assembly to be reduced below a fourth threshold value based on at least one of the above, and

[0060] When the load of the floor brush motor or the vacuum degree in the floor brush assembly does not drop below the fourth threshold, the air valve is controlled to be in the second position to increase the ventilation area of ​​the air inlet.

[0061] It is understandable that increasing the height of the block helps protect carpet fibers and handle large particles of dirt, avoiding damage to the cleaning surface. However, after increasing the height of the block, the current information, electric power information and vacuum information of the floor brush motor can also be monitored in real time, so that the cleaning equipment can accurately judge the current internal vacuum degree and floor brush motor load of the floor brush motor. If it is detected that the vacuum degree or motor load does not reach the ideal state, the valve can be further adjusted to increase the ventilation area of ​​the air inlet, which can optimize the suction and cleaning effect. This dynamic adjustment helps to quickly adapt to different cleaning needs and improve cleaning efficiency.

[0062] Therefore, by optimizing the position of the valve and the stopper, the floor brush motor can be prevented from overloading and the vacuum degree can be optimized, ensuring that the cleaning equipment operates in an ideal state and improving the flexibility of the cleaning equipment.

[0063] Optionally, an adjustment bin is provided at the front of the floor brush assembly, an adjustment mechanism is provided on the adjustment bin, a dust collection port is provided on the bottom surface of the adjustment bin, a bin cover is provided at the upper portion of the adjustment bin, an air inlet is provided on the bin cover, the adjustment mechanism comprises a block and an air valve for blocking the air inlet, the block is configured to move relative to the cleaning surface to change the degree to which the dust collection port is blocked by the block, and the ventilation area of ​​the air inlet is changed by adjusting the air valve, wherein controlling the adjustment mechanism to be in the target position comprises:

[0064] When it is identified that the material of the specific cleaning surface is non-carpet and the type of the specific dirt is the first type of dirt, controlling the stopper to be in the first position to increase the height of the stopper relative to the cleaning surface;

[0065] Alternatively, when it is identified that the material of the specific cleaning surface is a carpet and the carpet does not contain the first type of dirt, the air valve is controlled to be in the second position to increase the ventilation area of ​​the air inlet;

[0066] Alternatively, when it is identified that the material of the specific cleaning surface is carpet and the type of dirt on the carpet is first type of dirt, the block is controlled to be in the first position to increase the height of the block relative to the cleaning surface and the valve is in the second position to increase the ventilation area of ​​the air inlet.

[0067] In this way, when identifying different specific cleaning surface materials and specific dirt types, by combining the adjustment of the block and the valve, the cleaning equipment can be flexibly adjusted according to different cleaning environments and dirt types, thereby improving the flexibility of the cleaning equipment. Moreover, by dynamically adjusting the ventilation area of ​​the air inlet and the block height, the suction force can be optimized, thereby protecting the cleaning surface and the cleaning equipment. Especially when dealing with carpets and large particles of dirt, increasing the block height can protect carpet fibers and prevent clogging of the cleaning equipment. In addition, by optimizing the position of the valve and the block, the cleaning equipment can also operate in energy-saving mode, reducing energy consumption and preventing overload of the floor brush motor.

[0068] Optionally, the ventilation area of ​​the air inlet arranged at the upper part of the adjustment bin arranged at the front part of the floor brush assembly is changed by adjusting the position of the adjustment mechanism; and, when it is identified that the material of a specific cleaning surface is carpet, the ventilation area corresponding to the position where the adjustment mechanism is controlled is greater than the ventilation area corresponding to the position where the adjustment mechanism is controlled when it is identified that the material of the cleaning surface is non-carpet.

[0069] In this way, by changing the position of the adjustment mechanism to adjust the ventilation area of ​​the air inlet, the cleaning equipment can provide an ideal cleaning effect on cleaning surfaces of different materials. For cleaning surfaces of different materials, such as carpets or non-carpets, the adaptability of the cleaning equipment is improved by optimizing the ventilation area of ​​the air inlet. In addition, by adjusting the ventilation area of ​​the air inlet and optimizing the vacuum degree inside the floor brush assembly, it is also possible to avoid overloading the floor brush motor, extend the service life of the floor brush assembly, and improve energy efficiency.

[0070] It should also be noted that the above-mentioned automated adjustment mechanism reduces the need for users to manually adjust the floor brush assembly, thereby improving ease of use and comfort.

[0071] Optionally, when it is identified that the material of the specific cleaning surface is carpet, the ventilation area corresponding to the position where the adjustment mechanism is controlled is larger than the ventilation area corresponding to the position where the adjustment mechanism is controlled when it is identified that the material of the cleaning surface is non-carpet, including:

[0072] When it is identified that the pile length of the carpet is greater than or equal to the third threshold, the ventilation area corresponding to the position where the adjustment mechanism is controlled is greater than the ventilation area corresponding to the position where the adjustment mechanism is controlled when it is identified that the material of the cleaning surface is less than the third threshold.

[0073] In this way, when the length of the carpet pile is greater than or equal to the third threshold value, the vacuum degree inside the floor brush assembly can be reduced by increasing the ventilation area of ​​the air inlet, thereby preventing the carpet pile from being excessively pulled or damaged, which helps to protect the structural integrity of the carpet while ensuring effective cleaning. For carpets with shorter pile, the vacuum degree inside the floor brush assembly can be increased by reducing the ventilation area of ​​the air inlet, thereby increasing the suction force and enhancing the cleaning ability, ensuring that dust and dirt on the surface and deep layers of the carpet are effectively removed. Therefore, by adjusting the ventilation area of ​​the air inlet according to the length of the pile, and then adjusting the suction force, unnecessary wear or damage to the carpet material can be avoided, thereby extending the service life of the carpet.

[0074] In addition, the above-mentioned automatic adjustment mechanism enables the cleaning device to easily adapt to different types of carpets without the need to manually adjust other settings, thus improving the user experience.

[0075] Optionally, the ventilation area of ​​the air inlet is changed by moving a valve of the adjustment mechanism, the adjustment mechanism further includes a stopper, the position of the stopper is changed by adjusting the height of the stopper relative to the cleaning surface, and when it is identified that the material of the specific cleaning surface is a carpet, the adjustment mechanism is controlled to be in the second position, including:

[0076] When it is identified that the material of the specific cleaning surface is carpet, adjusting the position of the stopper to increase the height of the stopper relative to the cleaning surface; and

[0077] After adjusting the position of the stopper to increase the height of the stopper relative to the cleaning surface, the position of the air valve is adjusted to increase the ventilation area of ​​the air inlet.

[0078] Therefore, by adjusting the height of the block, the movement of the floor brush assembly on the carpet is smoother, direct contact with the carpet fibers is reduced, damage and wear are prevented, and the service life of the carpet is extended. The valve is further adjusted to increase the ventilation area of ​​the air inlet, further reducing the vacuum degree inside the floor brush assembly, reducing the suction effect on the carpet, and helping to avoid pulling and damaging the carpet fluff, ensuring the cleaning effect while protecting the carpet. In this way, by adjusting the block first and then adjusting the valve, the cleaning equipment can provide better cleaning effect on the carpet, while avoiding excessive adsorption of the carpet, reducing subsequent maintenance costs.

[0079] In a second aspect, the present disclosure provides a device for a cleaning device, the cleaning device comprising a floor brush assembly, the floor brush assembly comprising an adjustment mechanism and an optical sensor, different positions of the adjustment mechanism correspond to different vacuum degrees inside the floor brush assembly, and the device comprises:

[0080] An identification module, used to identify the type of dirt on the cleaning surface and / or the material of the cleaning surface based on the optical information detected by the optical sensor;

[0081] a control module, configured to control the adjustment mechanism to be in a target position based on the identified specific dirt type and / or the specific cleaning surface material, wherein the specific dirt type includes a first type of dirt, the first type of dirt is granular dirt having a diameter or height greater than or equal to a first threshold, and the specific cleaning surface material includes carpet;

[0082] The control module is specifically used for:

[0083] When it is identified that the specific type of dirt is the first type of dirt, the control adjustment mechanism is in the first position, and when it is identified that the material of the specific cleaning surface is carpet, the control adjustment mechanism is in the second position.

[0084] In a third aspect, the present disclosure provides a cleaning device, comprising a floor brush assembly, the floor brush assembly comprising an adjustment mechanism and an optical sensor, different positions of the adjustment mechanism correspond to different vacuum degrees inside the floor brush assembly, and the cleaning device is used to execute any method as described in the first aspect.

[0085] In a fourth aspect, the present disclosure provides an electronic device, comprising: a processor, and a memory communicatively connected to the processor;

[0086] Memory stores computer-executable instructions;

[0087] The processor executes the computer-executable instructions stored in the memory to implement any method as described in the first aspect.

[0088] In a fifth aspect, the present disclosure provides a computer-readable storage medium, wherein the computer-readable storage medium stores computer-executable instructions, and when the computer-executable instructions are executed by a processor, they are used to implement any method as in the first aspect.

[0089] In a sixth aspect, the present disclosure provides a computer program product, comprising a computer program, which implements any method in the first aspect when executed by a processor.

[0090] It should be noted that the second to sixth aspects of the present disclosure correspond to the technical solutions of the first aspect of the present disclosure, and the beneficial effects achieved by each aspect and the corresponding feasible implementation methods are similar, which will not be repeated here.

[0091] In summary, the present disclosure provides a method, device, equipment, medium and product for cleaning equipment, which automatically identifies the type and material of dirt on the cleaning surface by using an optical sensor and an adjustment mechanism, and adjusts the vacuum degree of the floor brush assembly accordingly, thereby solving problems in user experience, cleaning effect and product aspects. Specifically, the optical sensor is installed on the floor brush assembly to monitor the information on the cleaning surface in real time. The adjustment mechanism automatically adjusts the vacuum degree of the floor brush assembly according to the data collected by the optical sensor. The data collected by the optical sensor includes the material characteristics of the cleaning surface and the type of dirt. Based on the information detected by the optical sensor, the first type of dirt and / or the carpet material on the cleaning surface can be identified. The first type of dirt is granular dirt with a diameter or height greater than or equal to a preset threshold. When the first type of dirt is identified, the adjustment mechanism is adjusted to the first position to adapt to the cleaning of large particles of garbage. When the carpet material is identified, the adjustment mechanism is adjusted to the second position to reduce the vacuum degree, protect the carpet and improve operability. From the perspective of user experience, since the optical sensor can detect the type and material of dirt on the cleaning surface in real time, there is no need for users to observe and judge manually, which eliminates the burden of users frequently manually adjusting the equipment, simplifies the operation process, and improves user experience; from the perspective of cleaning effect, by identifying specific dirt types such as large particles and materials such as carpets, the equipment can automatically adjust to a suitable vacuum degree and the position of the adjustment mechanism, avoiding the problem of large particles of garbage getting stuck, and preventing the carpet from being damaged by excessive vacuum, thereby ensuring the cleaning effect while protecting the cleaning surface; and, from the perspective of product design, if a manual opening component is provided, it is necessary to ensure that its size is large enough so that the user can notice it and it is convenient to operate, and the technical solution disclosed in the present invention is adaptively adjusted, and there is no need to set a manual opening component, which reduces restrictions on the design of the floor brush.

For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can mean: a, b, c, ab, ac, bc, or abc, where a, b, c can be single or plural.

[0108] Under the premise of considering carpet and large particle cleaning, how to achieve adaptive cleaning without user perception is one of the problems that urgently needs to be solved. Existing cleaning equipment is usually equipped with an opening and closing plate. The main function of this opening and closing plate is to adjust the gap between the floor brush and the cleaning surface so as to better handle particles of different sizes or perform carpet cleaning.

[0109] However, for current cleaning equipment, from the user's perspective, the user needs to read the instructions or observe the floor brush parts before using the cleaning equipment to know the opening and closing plate and its opening parts, and when using the cleaning equipment, the user needs to always pay attention to the cleaning surface condition and manually operate the opening parts at the brush head in time based on the cleaning surface condition, which increases the user's burden in many aspects.

[0110] From the perspective of cleaning the cleaning surface, large particles of garbage may be stuck in the floor brush and cannot be cleaned. The carpet may not be pushed on the floor brush due to the high vacuum degree of the floor brush, and may even be damaged, resulting in poor overall cleaning effect of the cleaning equipment.

[0111] From the perspective of product design, existing cleaning equipment needs to take into account the limited surface of the floor brush and the size of the opening and closing plate and its opening parts, so that users can notice and perform related operations of the opening and closing plate and its opening parts conveniently, which complicates the design and increases the difficulty of design and manufacturing.

[0112] In view of the above problems, the present disclosure provides a method for a cleaning device, which automatically identifies the type and material of dirt on the cleaning surface by using an optical sensor and an adjustment mechanism, and adjusts the vacuum degree of the floor brush assembly accordingly, thereby solving problems in user experience, cleaning effect and product aspects. Specifically, the optical sensor is installed on the floor brush assembly to monitor the information on the cleaning surface in real time. The adjustment mechanism automatically adjusts the vacuum degree of the floor brush assembly according to the data collected by the optical sensor. The data collected by the optical sensor includes the material characteristics of the cleaning surface and the type of dirt. Based on the information detected by the optical sensor, the first type of dirt and / or carpet material on the cleaning surface can be identified. The first type of dirt is particles whose diameter or height is greater than or equal to a preset threshold. When the first type of dirt is identified, the adjustment mechanism is adjusted to the first position to adapt to the cleaning of large particles of garbage. When the carpet material is identified, the adjustment mechanism is adjusted to the second position to reduce the vacuum degree, protect the carpet and improve operability. Since the optical sensor can detect the type and material of dirt on the cleaning surface in real time, there is no need for users to manually observe and judge, which eliminates the burden of users needing to frequently manually adjust the equipment, simplifies the operating process, and improves user experience. In addition, by identifying specific dirt types such as large particles and materials such as carpets, the equipment can automatically adjust to a suitable vacuum degree and the position of the adjustment mechanism, avoiding the problem of large particles of garbage getting stuck and preventing the carpet from being damaged due to excessive vacuum, ensuring the cleaning effect while protecting the cleaning surface.

[0113] In addition, since the cleaning device can automatically adjust the position of the adjustment mechanism according to different types of dirt and / or the material of the cleaning surface, it ensures that the ideal cleaning effect can be achieved in various situations. The above process is automated. Therefore, the user does not need to read complicated instructions or perform frequent manual operations. The cleaning device can automatically adapt to different cleaning environments.

[0114] Optionally, the method for cleaning equipment provided by the present disclosure is applied to cleaning equipment, exemplarily, Figure 1 A partial structural diagram of a cleaning device provided in an embodiment of the present disclosure is shown in FIG. Figure 1 As shown, the cleaning device 200 includes a floor brush assembly 100, and the floor brush assembly 100 includes an adjustment mechanism 101 and an optical sensor 102. Different positions of the adjustment mechanism 101 correspond to different vacuum degrees inside the floor brush assembly 100.

[0115] For example, Figure 2 A partial structural diagram of a floor brush assembly provided in an embodiment of the present disclosure is shown in FIG. Figure 2As shown, the floor brush assembly 100 includes a floor brush housing 103 and an adjustment mechanism 101 arranged at the front of the floor brush assembly 100. The position of the adjustment mechanism 101 relative to the cleaning surface is determined based on the type of dirt located on the cleaning surface and / or the material of the cleaning surface, and different positions of the adjustment mechanism 101 correspond to different vacuum degrees inside the floor brush assembly 100.

[0116] Optionally, an adjustment chamber 104 is provided at the front of the floor brush assembly 100, and the adjustment mechanism 101 is provided on the adjustment chamber 104. For example, Figure 3 An exploded diagram of a floor brush assembly provided in an embodiment of the present disclosure, such as Figure 3 As shown, the bottom surface of the adjustment bin 104 is provided with a dust collection port 11, and the adjustment mechanism 101 includes a stopper 12, and the stopper 12 is configured to move relative to the cleaning surface to change the degree to which the dust collection port 11 is blocked by the stopper 12;

[0117] The position of the adjustment mechanism 101 includes the height of the stopper 12 relative to the cleaning surface.

[0118] Optional, such as Figure 3 As shown, the optical sensor 102 includes a light emitter 121 and a light receiver 122; at least part of the light emitted by the light emitter 121 is received by the light receiver 122, and in the presence of a specific type of dirt and / or material of the cleaning surface, the light emitted by the light emitter 121 is at least partially blocked, and the identification of the type of dirt on the cleaning surface and / or the material of the cleaning surface is at least partially based on the light received by the light receiver 122.

[0119] Optional, such as Figure 3 As shown, a bin cover 13 is provided on the upper part of the adjustment bin 104 arranged at the front part of the floor brush assembly 100, and an air inlet 14 is provided on the bin cover 13. The adjustment mechanism 101 includes a block 12 and a valve 15 for blocking the air inlet 14. The block 12 is configured to move relative to the cleaning surface to change the degree to which the dust collecting port 11 is blocked by the block 12. The ventilation area of ​​the air inlet 14 is changed by adjusting the valve 15.

[0120] The position of the valve 15 can be adjusted as needed to control the opening size of the air inlet 14 . By changing the position of the valve 15 , the regulating mechanism 101 can accurately control the air flow entering the floor brush assembly 100 .

[0121] Optionally, the cleaning device 200 also includes at least one of a current sensor (not shown in the figure) for detecting current information of the floor brush motor, an electric power sensor (not shown in the figure) for detecting electric power information of the floor brush motor, and a vacuum sensor (not shown in the figure) for detecting vacuum information in the floor brush assembly. The identification of the specific type of dirt on the cleaning surface and / or the specific material of the cleaning surface is based on at least one of the current information, electric power information, and vacuum information.

[0122] Among them, the current change can reflect the change in the load of the floor brush motor, indirectly indicating the material of the cleaning surface or the type of dirt. The power change can provide comprehensive information about the working status of the floor brush motor, and can also indirectly reflect the specific material or type of dirt on the cleaning surface. The vacuum change can indicate the change in suction force, reflecting the density of the material of the specific cleaning surface or the amount of dirt. Therefore, current information, electric power information, and vacuum information can also be used as optional methods to identify the specific type of dirt on the cleaning surface and / or the specific material of the cleaning surface.

[0123] Based on the above structural design of the cleaning device 200, the user does not need to understand or study the detailed components of the device before using the cleaning device 200. Moreover, during use, the user does not need to pay attention to the condition of the cleaning surface or manually adjust the floor brush assembly 100. It is completely based on automatic adjustment and can complete the cleaning of various dust and / or cleaning surface conditions in one go, which greatly simplifies the operating steps. Moreover, the cleaning device 200 can automatically identify and adapt to different cleaning surface materials and types of dirt. The user only needs to start the device to complete the cleaning task, and the user experience is greatly improved.

[0124] In addition, the cleaning device 200 can finely control the adjustment structure 101 according to different cleaning surface textures and dust sizes, ensuring that each type of cleaning surface and dirt can be effectively cleaned. This fine control not only improves the cleaning effect, but also effectively avoids damage to the cleaning surface.

[0125] It should also be noted that since the adjustment mechanism 101 is adaptively adjusted, there is no need to set a large component on the surface of the floor brush assembly 100 for the user to manually operate the opening and closing plate, which reduces the restrictions on the floor brush design and reduces unnecessary mechanical parts, making the product more compact and beautiful.

[0126] For example, Figure 4 A schematic diagram of an application scenario provided by an embodiment of the present disclosure, taking the cleaning device 200 as a vacuum cleaner as an example, Figure 4As shown, the application scenario includes a vacuum cleaner having a floor brush assembly 100. Taking carpet cleaning as an example, when the vacuum cleaner cleans the carpet, it can identify that the material of the cleaning surface is carpet based on the optical information detected by the optical sensor. Furthermore, the position of the adjustment mechanism is controlled to change so that it is in a corresponding position to reduce the vacuum degree and reduce the resistance between the roller brush in the floor brush assembly 100 and the carpet.

[0127] Optionally, the vacuum cleaner can also identify the type of dirt on the cleaning surface based on the optical information detected by the optical sensor. When the type of dirt on the cleaning surface is identified as large particles of dirt based on the optical information, the position of the adjustment mechanism can also be controlled to change so that it is in a corresponding position to allow large particles of dirt to enter and avoid blockage.

[0128] It should be noted that the embodiment of the present disclosure does not specifically limit the type of the cleaning device 200 , which may be a vacuum cleaner, a floor scrubber, etc.

[0129] It should also be noted that the present disclosure does not specifically limit the application scenarios of the cleaning device 200, and it can be applied to home scenarios, shopping mall scenarios, school scenarios, and office scenarios.

[0130] It should be noted that, in the present disclosure, the floor brush assembly may also be referred to as a floor brush.

[0131] The technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0132] Figure 5 A schematic diagram of a method for cleaning equipment provided in an embodiment of the present disclosure is shown in FIG. Figure 5 As shown, the method for cleaning the device is applied to Figure 1-Figure 3 In the cleaning device shown; the self-cleaning method of the cleaning device comprises the following steps:

[0133] S501 : Identify the type of dirt on the cleaning surface and / or the material of the cleaning surface based on the optical information detected by the optical sensor.

[0134] In the disclosed embodiments, an optical sensor is used to capture optical information on a cleaning surface in real time. The optical information may include characteristics of the cleaning surface such as light intensity, light energy, and reflectivity. The cleaning device then identifies different types of dirt and the material of the cleaning surface (such as hard floors or carpets) based on the optical information. The dirt type may include particles of different sizes and shapes, and the material of the cleaning surface may include carpet or non-carpet.

[0135] Among them, carpet can refer to the cleaning surface of the soft surface with fluff or fiber, and non-carpet can refer to the cleaning surface of the hard surface or fluff-free surface, such as wooden floors, tiles and other cleaning surfaces.

[0136] It should be noted that optical sensors have high detection accuracy and can not only detect the presence of large particles of garbage, but also identify the material of the cleaning surface, such as carpet or non-carpet.

[0137] S502. Controlling the adjustment mechanism to be in a target position based on the identified specific dirt type and / or specific cleaning surface material, wherein the specific dirt type includes a first type of dirt, which is granular dirt having a diameter or height greater than or equal to a first threshold, and the specific cleaning surface material includes carpet.

[0138] Among them, specific dirt types include granular dirt, such as particles with a diameter or height greater than or equal to a first threshold, these particles may be sand, soybeans, small stones, dust, etc. Specific cleaning surface materials include carpets, and carpet materials usually require special cleaning methods, such as requiring stronger suction for cleaning.

[0139] In the disclosed embodiment, the first threshold is a size standard for distinguishing different types of granular dirt. The first threshold is a preset value used to determine the diameter or height of the granular dirt so as to classify the dirt into first-category dirt or second-category dirt. For example, soybeans, pebbles, and other particles with a diameter or height greater than or equal to 2 mm are first-category dirt, and fine dust or microparticles with a diameter or height less than 2 mm are second-category dirt. The disclosed embodiment does not specifically limit the size of the first threshold, and it can be set based on the product performance parameters of the floor brush assembly.

[0140] Optionally, the first threshold is a value between 1 mm and 10 mm.

[0141] In the disclosed embodiment, the lower limit of 1 mm is set to ensure that very fine granular dirt, such as dust and fine sand, can be effectively identified and processed. These tiny particles usually require higher suction and tighter contact with the floor brush to be effectively removed; the upper limit of 10 mm is set to cover larger particles of dirt, such as debris, pebbles, etc. These larger particles require reducing the suction or increasing the distance between the adjustment mechanism 101 and the cleaning surface to avoid blockage. In this way, within this range of 1 mm to 10 mm, the adjustment mechanism 101 can dynamically adjust its position according to the detected dirt size.

[0142] In some embodiments, the first type of dirt is a diameter or height of less than 7 mm and greater than 2 mm.

[0143] Therefore, setting the first threshold as a range provides greater flexibility. By dynamically adjusting the threshold between 1mm and 10mm, the floor brush assembly can adapt to a variety of cleaning scenarios and thus can more effectively handle various types of dirt from fine dust to larger particles. This flexibility allows the floor brush assembly to automatically select the appropriate cleaning mode under different cleaning surface materials and dirt conditions, thereby increasing the scope of application.

[0144] Among them, S502 specifically includes:

[0145] S5021. When the specific dirt type is identified as the first type of dirt, the control adjustment mechanism is in the first position; and when the specific cleaning surface material is identified as carpet, the control adjustment mechanism is in the second position.

[0146] In this step, when the adjustment mechanism is in the first position, the vacuum degree inside the floor brush assembly is reduced so that large particles can enter more easily. When the adjustment mechanism is in the second position, the vacuum degree inside the floor brush assembly is also reduced so as to reduce the resistance to the carpet fluff, prevent the floor brush motor from overloading, and make the floor brush assembly easier to move on the carpet.

[0147] It should be noted that the first position and the second position of the adjustment structure may be the same position or different positions, and the embodiment of the present disclosure does not specifically limit this.

[0148] For example, Figure 6 A schematic diagram of the position of an adjustment structure provided in an embodiment of the present disclosure, in which, when the cleaning device identifies that the type of specific dirt is the first type of dirt, the control adjustment mechanism is in the following position: Figure 6 Alternatively, when the cleaning device identifies that the material of the specific cleaning surface is carpet, the control adjustment mechanism is in the first position as shown in Figure 6 The second position shown in the figure is a position where the adjustment mechanism is at a certain height from the cleaning surface, that is, a position where the dust collecting port 11 is less blocked.

[0149] Optional, Figure 7 A schematic diagram of the position of another adjustment structure provided in an embodiment of the present disclosure, such as Figure 7 As shown, when the cleaning device recognizes that the material of the specific cleaning surface is carpet, the control adjustment mechanism is in the following state: Figure 7 The second position is shown in FIG. 1 , where the ventilation area of ​​the air inlet 14 is larger.

[0150] Thus, in the present disclosure, the cleaning device can automatically identify the specific type of dirt and / or the material of the specific cleaning surface based on the optical sensor, and then dynamically adjust the position of the adjustment mechanism based on the identified specific type of dirt and / or the material of the specific cleaning surface, without the need for manual intervention, thereby greatly improving the cleaning efficiency. In particular, when dealing with large particles of dirt or carpets, the adjustment mechanism can be controlled to automatically adjust to a suitable position, thereby quickly and effectively completing the cleaning task. For example, for large particles of dirt, by changing the height of the adjustment structure relative to the cleaning surface, large particles of garbage are allowed to enter the floor brush assembly to avoid blockage; for carpets, the vacuum degree can be reduced to reduce resistance, making the floor brush assembly easier to push on the carpet, preventing the carpet fluff from being excessively pulled or damaged, and also reducing the load on the floor brush motor, avoiding unnecessary high-load operation, thereby reducing the risk of overloading the floor brush motor and helping to extend the service life of the floor brush motor.

[0151] Therefore, by identifying the specific type of dirt and the specific material of the cleaning surface, the cleaning equipment can adjust the cleaning strategy in a targeted manner. This precise processing method ensures that different types of dirt and cleaning surface materials can achieve ideal cleaning results.

[0152] Optionally, the moving position of the adjustment mechanism can also be changed according to the different loads brought by the type of specific cleaning surface, so that the load of the floor brush motor is always maintained within a certain range, for example, the range is that the load of the floor brush motor is less than or equal to 120% of the rated power.

[0153] Optionally, the optical information includes a signal waveform, wherein identifying a specific type of dirt and / or a specific material of the cleaning surface based on the optical information includes at least one of the following:

[0154] determining the type of the specific contamination as first type contamination based on the signal waveform, and

[0155] The material of the specific cleaning surface is determined to be carpet based on the signal waveform.

[0156] The signal waveform may include characteristics such as frequency, amplitude, phase, etc., and the signal waveform may reflect the material of the cleaning surface and the physical characteristics of the dirt, such as the signal waveform may provide characteristics such as the size, shape, and density of the dirt. Therefore, by analyzing the characteristics of the signal waveform, the specific type of dirt and the specific material of the cleaning surface may be identified.

[0157] For example, based on the characteristics of the signal waveform, such as a specific reflection intensity or waveform change, the first type of dirt, i.e., granular dirt having a diameter or height greater than or equal to a first threshold, can be identified. Accordingly, the carpet material can also be identified by analyzing the characteristics of the waveform.

[0158] It is understandable that the signal waveform provides richer information, making the process of identifying the first type of dirt and carpet more accurate. For example, simply comparing the optical information provided by the optical sensor with the threshold value may cause misjudgment or even fail to distinguish the first type of dirt and carpet. By analyzing the signal waveform, misjudgment can be reduced and the reliability of identification can be improved. In addition, the signal waveform analysis can be performed quickly, so that the cleaning device can detect the first type of dirt or carpet in real time, and then select the appropriate cleaning method, thereby improving the cleaning effect while avoiding damage to the cleaning surface and extending the service life of the cleaning surface.

[0159] Optionally, the signal waveform is a waveform of an optical signal that changes over time. For example, when a user pushes a floor brush to move on a cleaning surface over time, an optical sensor on the floor brush can detect dirt and cleaning surface conditions at various locations along the moving path of the floor brush in real time. Specifically:

[0160] In the case where the signal waveform indicates a transient change, determining the type of the specific contamination is first type of contamination, and

[0161] When the signal waveform indicates a continuous change, it is determined that the material of the specific cleaning surface is carpet.

[0162] In the embodiments of the present disclosure, the optical signal may form a waveform as it changes over time to reflect the characteristics of the clean surface and dirt. The signal waveform may indicate an instantaneous change or a continuous change. An instantaneous change refers to a rapid change in the signal waveform within a short period of time. This change is usually manifested as a sudden rise or fall in the waveform, similar to a spike or pulse. For example, when the optical sensor of the cleaning equipment encounters a large particle of dust, the intensity of the light received by the optical sensor will increase or decrease instantaneously, resulting in an obvious peak in the signal waveform.

[0163] Continuous change means that the signal waveform fluctuates around a higher amplitude for a longer period of time. For example, when the light emitted by the optical sensor of the cleaning equipment scans the carpet, due to the complexity of the carpet fibers, the intensity of the light received by the optical sensor's light receiver will fluctuate continuously as the optical sensor on the floor brush moves, which is manifested as continuous ups and downs on the waveform, thus forming a regular fluctuation pattern.

[0164] In this way, by analyzing the instantaneous change characteristics and continuous changes of the waveform, the cleaning equipment can quickly and accurately identify the specific type of dirt on the cleaning surface and the specific material of the cleaning surface, thereby improving cleaning efficiency, and the cleaning equipment can analyze and respond to the signal waveform in real time, thereby ensuring that it can quickly adapt to environmental changes during the cleaning process and provide instant cleaning adjustments. In addition, by identifying special materials such as carpets, the cleaning equipment can select appropriate cleaning methods and avoid using cleaning strategies that may damage the cleaning surface, thereby extending the service life of the cleaning surface.

[0165] Optionally, the method further includes:

[0166] When the specific type of dirt is identified as the second type of dirt, the control adjustment mechanism is in the third position;

[0167] The second type of dirt is granular dirt with a diameter or height smaller than the first threshold value, and the height of the adjustment mechanism from the cleaning surface when the adjustment mechanism is in the third position is smaller than the height from the cleaning surface when the adjustment mechanism is in the first position.

[0168] In this step, when in the third position, the height of the adjustment mechanism from the cleaning surface is less than that in the first position. This adjustment enables the cleaning device to be closer to the cleaning surface, thereby more effectively removing fine particles.

[0169] For example, Figure 8 A schematic diagram of the position of another adjustment mechanism provided in an embodiment of the present disclosure is shown in FIG. Figure 8 As shown, when the cleaning device identifies that the type of specific dirt is the second type of dirt, the control adjustment mechanism is in the third position, so that the adjustment mechanism is closer to the cleaning surface, the vacuum degree is increased, so as to more effectively absorb fine dirt. When the adjustment mechanism 101 is in the second position, it is slightly away from the cleaning surface to allow larger particles to enter and avoid clogging and excessive absorption. Optionally, as Figure 6 As shown, when the cleaning device identifies that the specific type of dirt is the first type of dirt, the control adjustment mechanism is in the first position. When the adjustment mechanism is in the first position, it is slightly away from the cleaning surface to allow larger particles to enter and avoid blockage and excessive adsorption.

[0170] Therefore, for particles of different sizes and heights, by changing the height of the adjustment mechanism from the cleaning surface, particles of different sizes and heights can be easily entered. The height of the adjustment mechanism from the cleaning surface is different, and the corresponding vacuum degree is different. For larger particles, the height of the adjustment mechanism from the cleaning surface is increased to avoid blockage; for fine dust, the suction force is increased to ensure thorough cleaning. In this way, through optimized settings for different types of dirt and intelligent adjustment of the suction force, it can be ensured that the ideal cleaning effect can be achieved in various situations, and unnecessary energy consumption can be avoided, thereby improving the energy efficiency of the cleaning equipment. In addition, the above-mentioned automatic adjustment mechanism also reduces the need for manual adjustment by the user, making the cleaning process smoother and more efficient, thereby improving the cleaning efficiency.

[0171] Optionally, the method further includes:

[0172] When it is identified that the material of the specific cleaning surface is non-carpet, the control adjustment mechanism is in the fourth position;

[0173] Wherein, when the adjustment mechanism is in the second position, the height from the cleaning surface is greater than the height from the cleaning surface when the adjustment mechanism is in the fourth position.

[0174] In the disclosed embodiment, when the adjustment mechanism is in the fourth position, the gap between the floor brush assembly and the cleaning surface is smaller, thereby increasing the vacuum degree inside the floor brush assembly to enhance the adsorption capacity for dust and fine particles on non-carpet surfaces; when the adjustment mechanism is in the second position, the gap between the floor brush assembly and the cleaning surface is larger, thereby reducing the vacuum degree inside the floor brush assembly to reduce resistance to carpet fluff, prevent overloading of the floor brush motor, and make the floor brush assembly easier to move on the carpet.

[0175] It should be noted that the fourth position and the third position may be the same position or different positions, and the embodiment of the present disclosure does not specifically limit this.

[0176] For example, when it is identified that the material of the specific cleaning surface is not carpet, the control adjustment mechanism is in the following state: Figure 8 The fourth position shown in the figure makes the floor brush assembly closer to the cleaning surface to enhance the cleaning effect; when the material of the specific cleaning surface is identified as carpet, the control adjustment mechanism is in the following position: Figure 6 The second position shown in the figure makes the floor brush assembly have a greater height from the cleaning surface to protect the carpet fibers.

[0177] Therefore, on non-carpets, the smaller gap between the adjustment mechanism and the cleaning surface enhances the suction force and improves the cleaning ability of dust and fine particles. On carpets, the larger gap between the adjustment mechanism and the cleaning surface can adjust the vacuum degree, reduce the resistance to the fluff, avoid overloading the floor brush motor, and improve the mobility of the floor brush assembly. In this way, by adjusting the position of the adjustment mechanism according to the identified cleaning surface material, it can provide ideal cleaning effects on different cleaning surface types. In addition, there is no need for the user to manually adjust the floor brush assembly. The cleaning equipment can automatically adjust the position of the adjustment mechanism according to the detected cleaning surface material, thereby improving ease of use and user experience.

[0178] Optionally, when it is identified that the specific dirt type is the first type of dirt, controlling the regulating mechanism to be in the first position includes:

[0179] When the specific type of soiling is identified as the first type of soiling, the first position of the adjustment mechanism is determined based on the diameter or height of the first type of soiling.

[0180] For example, after identifying the first type of dirt, the specific diameter or height of these particles can be further measured, and then the adjustment mechanism can be dynamically adjusted to the first position based on the measured dirt size. The specific height or suction setting of the first position will be optimized according to the size of the dirt to ensure that the first type of dirt is effectively removed.

[0181] In this way, by dynamically adjusting the position of the adjusting mechanism according to the specific size of the dirt, it is ensured that the cleaning equipment can effectively handle particles of various sizes, thereby improving the cleaning effect. By optimizing the position of the adjusting mechanism, the risk of large particles of garbage getting stuck in the cleaning equipment can also be reduced, thereby ensuring the stable operation of the cleaning equipment. In addition, the above-mentioned automated size measurement and adjustment reduces the need for manual operation by the user, simplifies the operating process, improves user satisfaction, and makes the present disclosure applicable to handling dirt of various types and sizes, thereby increasing the breadth of application.

[0182] Optionally, determining the first position of the adjustment mechanism based on the diameter or height of the first type of dirt includes: determining the height of the stopper relative to the cleaning surface based on the diameter or height of the first type of dirt.

[0183] In this step, the height of the block relative to the cleaning surface can be determined based on the measured size of the dirt, and then the position of the block can be adjusted based on the determined height of the block relative to the cleaning surface to change the opening size of the dust collecting port, so that it can adapt to dirt of different sizes, and in particular ensure that the dust collecting port can effectively absorb large particles of dirt.

[0184] In this way, the position of the stopper is accurately adjusted according to the diameter or height of the first type of dirt to adaptively control the opening degree of the dust collecting port, so that the cleaning equipment can optimize the opening size of the dust collecting port according to the specific size of the dirt, ensuring that the dirt is effectively removed, and precise adjustment can also reduce cleaning time and energy consumption, because the cleaning equipment can handle large particles of dirt more effectively, and also reduce the risk of large particles of garbage getting stuck in the cleaning equipment.

[0185] Optionally, the method further includes:

[0186] determining light intensity information or light energy information as optical information based on the light received by the light receiver;

[0187] When the light intensity information or the light energy information is less than or equal to the second threshold, the specific type of dirt is determined to be the first type of dirt.

[0188] In the disclosed embodiments, when there is a specific type of dirt on the cleaning surface or a specific material of the cleaning surface, such as large particles of dirt or carpet, the light emitted by the light transmitter will be partially blocked. This blockage will cause the light intensity or energy received by the light receiver to change. Therefore, the light intensity information or light energy information can be determined based on the light received by the light receiver.

[0189] Exemplarily, if the light intensity information or the light energy information is less than or equal to a preset second threshold, it can be determined that the first type of dirt, i.e., large-particle dirt, exists. This judgment is based on the blocking effect of large-particle dirt on light. For example, when the cleaning surface of the front section of the brush assembly has large particles such as soybeans and pebbles, the large particles will block at least part of the light emitted by the light transmitter, resulting in a decrease in the light intensity or light energy received by the light receiver.

[0190] In addition, the light transmitter and the light receiver can also help to identify long-haired carpets and other cleaning surface media. For example, when the floor brush assembly is on a medium such as a long-haired carpet, the carpet with longer hair will also block at least a portion of the light emitted by the light transmitter. At this time, if the detected light intensity or light energy is reduced, it can be determined that the carpet is a long-haired carpet.

[0191] Therefore, through the cooperation of the light emitter and the light receiver, the floor brush assembly can detect changes in light, and then determine changes in light intensity or light energy based on the light information received by the light receiver, so as to accurately identify whether the specific type of dirt is the first type of dirt. This accurate identification reduces the possibility of misjudgment and helps to optimize the cleaning strategy. In addition, the light emitter and light receiver can also monitor changes on the cleaning surface in real time and quickly identify different dirt conditions and material types.

[0192] Optionally, the method further includes:

[0193] When it is identified that the material of the specific cleaning surface is a carpet, determining the pile length of the carpet based on the optical information;

[0194] If the pile length of the carpet is greater than or equal to a third threshold, the control adjustment mechanism is in a fifth position;

[0195] If the pile length of the carpet is less than the third threshold, the control adjustment mechanism is in the sixth position;

[0196] Wherein, when the adjustment mechanism is in the fifth position, the height from the cleaning surface is greater than the height from the cleaning surface when the adjustment mechanism is in the sixth position.

[0197] In the disclosed embodiment, the optical information can also reflect the height of the pile, because longer pile will cause more light scattering or blocking. If the measured pile length is greater than or equal to a preset third threshold, the carpet pile is considered to be longer; if the pile length is less than the third threshold, the carpet pile is considered to be shorter.

[0198] Among them, the third threshold is a key parameter for distinguishing long-pile carpets from short-pile carpets. The third threshold can be set according to the range of the carpet's pile length, or it can be set based on the product performance parameters of the floor brush assembly. The embodiment of the present disclosure does not specifically limit the size of the third threshold.

[0199] Optionally, the third threshold is a value between 1 mm and 10 mm.

[0200] In the disclosed embodiment, the threshold of the carpet pile length is selected to be between 1 mm and 10 mm, which can cover most carpet types, wherein the lower limit of 1 mm is set to ensure that short-pile carpets can be effectively identified and determined. On short-pile carpets, smaller gaps can enhance suction and improve the cleaning ability for dust and fine particles. The upper limit of 10 mm is set to ensure that long-pile carpets can be effectively identified and determined. On long-pile carpets, larger gaps can reduce resistance to the pile and improve the mobility and cleaning efficiency of the cleaning device. In this way, within this range of 1 mm to 10 mm, the adjustment mechanism can dynamically adjust its position according to the detected carpet pile length.

[0201] Therefore, setting the third threshold as a range provides greater flexibility. By dynamically adjusting the threshold between 1 mm and 10 mm, it is ensured that the cleaning device can provide ideal cleaning effects on both long-pile and short-pile carpets and avoid the problem of excessive or insufficient adsorption. Moreover, by setting a reasonable third threshold, the cleaning device can more accurately identify the carpet type, thereby providing more effective cleaning on different carpets and improving application flexibility.

[0202] For example, Figure 6 As shown in FIG. 1 , when it is determined based on the optical information that the length of the carpet's pile is greater than or equal to the third threshold, the adjustment mechanism is controlled to be in the fifth position. At the fifth position, the gap between the adjustment mechanism and the cleaning surface is larger to reduce the resistance to the long pile, prevent the floor brush motor from overloading, and make the floor brush easier to move on the carpet, as shown in FIG. Figure 8 As shown, when it is determined based on optical information that the pile length of the carpet is less than the third threshold, the control adjustment mechanism is in the sixth position. At the sixth position, the gap between the adjustment mechanism and the cleaning surface is smaller to enhance the adsorption capacity of dust and fine particles on the short-pile carpet.

[0203] In this way, on long-pile carpets, the adjustment mechanism has a larger gap from the cleaning surface to reduce resistance to the pile, prevent excessive wear and damage to carpet fibers, extend the service life of the carpet, and avoid overloading the floor brush motor, while improving the mobility of the floor brush assembly. On short-pile carpets, the adjustment mechanism has a smaller gap from the cleaning surface to enhance suction and improve the cleaning ability of dust and fine particles. In this way, by optically identifying the length of carpet pile and adjusting the position of the adjustment mechanism, ideal cleaning effects can be provided on different types of carpets. In addition, by appropriately adjusting the position of the adjustment mechanism, excessive loading of the floor brush motor on carpets with different pile lengths can also be avoided.

[0204] It should be noted that the user does not need to manually adjust the floor brush assembly. The floor brush assembly will automatically adjust the position of the adjustment mechanism according to the detected carpet pile length, thereby improving ease of use and user experience.

[0205] Optionally, the method further includes:

[0206] Identifying a special cleaning condition based on the optical information, wherein the special cleaning condition includes a specific type of dirt and / or a specific material of the cleaning surface; and

[0207] When a special cleaning condition is identified, it is determined whether the special cleaning condition is a specific type of dirt or a specific material of the cleaning surface based on comprehensive information, wherein the comprehensive information includes at least one of optical information, current information, electric power information, and vacuum degree information.

[0208] In the present disclosure, based on the comprehensive information, the cleaning device can more accurately determine whether a special cleaning condition is caused by a specific type of dirt or a specific cleaning surface material.

[0209] Optionally, special cleaning conditions are identified based on optical information. The main advantage is high sensitivity and the ability to quickly identify changes on the cleaning surface, such as dust or large particles. However, the accuracy of optical detection may be affected by changes in ambient light and the material of the cleaning surface. Therefore, misjudgment may occur in some cases. To solve this problem, when the optical information identifies a special cleaning condition, the cleaning equipment can start other relevant detections of the floor brush motor as a means of verification, such as by analyzing at least one of the current information, electric power information, and vacuum information to determine the cleaning surface condition.

[0210] It should be noted that although the response speed of other related detections of the floor brush motor is slow, its high precision can effectively compensate for the shortcomings of optical detection.

[0211] For example, after identifying a special cleaning condition based on optical information, the cleaning device can record the characteristics of the optical information and monitor the change of vacuum degree based on the vacuum degree information. If the optical information and vacuum degree information point to the presence of large particles, the load change of the floor brush motor can be further analyzed. If the load change of the floor brush motor is not large, the presence of large particles can be confirmed; if the load increases significantly, it may be caused by soft materials such as carpets. The load change can be determined based on the current information and the electric power information.

[0212] In this way, by combining information from multiple sensors, the cleaning equipment can more accurately identify special cleaning conditions and reduce misjudgments. This multi-sensor fusion design improves the intelligence level of the cleaning equipment, enabling it to adapt more flexibly to different cleaning scenarios. Without manual intervention by the user, the cleaning equipment can automatically identify the specific type of dirt and / or the material of the cleaning surface to adjust the position of the adjustment mechanism, thereby simplifying operation and improving user experience.

[0213] It is understandable that after accurately identifying the special cleaning conditions, the cleaning equipment can select the appropriate cleaning strategy to ensure the ideal cleaning effect.

[0214] Optionally, controlling the regulating mechanism to be in a target position includes:

[0215] When it is identified that the material of the specific cleaning surface is non-carpet and the type of the specific dirt is the first type of dirt, controlling the stopper to be in the first position to increase the height of the stopper relative to the cleaning surface;

[0216] When it is identified that the material of the specific cleaning surface is carpet, the stopper is controlled to be in the first position to increase the height of the stopper relative to the cleaning surface.

[0217] Detect at least one of the current information of the floor brush motor, the electric power information of the floor brush motor, and the vacuum degree information in the floor brush assembly,

[0218] determining whether the step of controlling the stopper to be in the first position causes the load of the floor brush motor or the vacuum degree in the floor brush assembly to be reduced below a fourth threshold value based on at least one of the above, and

[0219] When the load of the floor brush motor or the vacuum degree in the floor brush assembly does not drop below the fourth threshold, the air valve is controlled to be in the second position to increase the ventilation area of ​​the air inlet.

[0220] In this step, if it is identified that the material of the specific cleaning surface is non-carpet and the type of specific dirt is the first type of dirt, or if the material of the specific cleaning surface is identified as carpet, the cleaning device controls the block to be in the first position to increase the height of the block relative to the cleaning surface, which is helpful to deal with large particles of dirt or protect carpet fibers. Accordingly, in order to verify whether the ideal cleaning effect is achieved, the cleaning device will further detect at least one of the current information, electric power information and vacuum information of the floor brush motor and the floor brush assembly, and then based on at least one of the sensor information, determine whether the block in the first position causes the load of the floor brush motor or the vacuum degree in the floor brush assembly to drop below the fourth threshold. The purpose of this step is to determine whether the vacuum degree inside the floor brush assembly is at an appropriate level and will not cause the floor brush motor to overload. If the load or vacuum degree of the floor brush motor does not drop below the fourth threshold, the valve can be further controlled to be in the second position to increase the ventilation area of ​​the air inlet, thereby reducing the vacuum degree inside the floor brush assembly.

[0221] It is understandable that increasing the height of the block helps protect carpet fibers and handle large particles of dirt, avoiding damage to the cleaning surface. However, after increasing the height of the block, the current information, electric power information and vacuum information of the floor brush motor can also be monitored in real time, so that the cleaning equipment can accurately judge the current internal vacuum degree and floor brush motor load of the floor brush motor. If it is detected that the vacuum degree or motor load does not reach the ideal state, the valve can be further adjusted to increase the ventilation area of ​​the air inlet, which can optimize the suction and cleaning effect. This dynamic adjustment helps to quickly adapt to different cleaning needs and improve cleaning efficiency.

[0222] Therefore, by optimizing the position of the valve and the stopper, the floor brush motor can be prevented from overloading and the vacuum degree can be optimized, ensuring that the cleaning equipment operates in an ideal state and improving the flexibility of the cleaning equipment.

[0223] Optionally, controlling the regulating mechanism to be in a target position includes:

[0224] When it is identified that the material of the specific cleaning surface is non-carpet and the type of the specific dirt is the first type of dirt, controlling the stopper to be in the first position to increase the height of the stopper relative to the cleaning surface;

[0225] Alternatively, when it is identified that the material of the specific cleaning surface is a carpet and the carpet does not contain the first type of dirt, the air valve is controlled to be in the second position to increase the ventilation area of ​​the air inlet;

[0226] Alternatively, when it is identified that the material of the specific cleaning surface is carpet and the type of dirt on the carpet is first type of dirt, the block is controlled to be in the first position to increase the height of the block relative to the cleaning surface and the valve is in the second position to increase the ventilation area of ​​the air inlet.

[0227] For example, when it is identified that the material of the specific cleaning surface is non-carpet and the specific dirt type is the first type of dirt, the control block is in the following position: Figure 6 In the first position shown in FIG. 1 , when it is identified that the material of the specific cleaning surface is a carpet and there is no first type of dirt on the carpet, the control valve is in the following Figure 7 In the second position shown in FIG. 1 , when it is identified that the material of the specific cleaning surface is carpet and the type of dirt on the carpet is the first type of dirt, the control block and the valve are in the following position: Fig. 9 The location shown in .

[0228] It should be noted that the embodiment of the present disclosure does not limit the specific positions corresponding to the first position and the second position. The first position may correspond to a position where the dust collecting port is at least partially blocked by the baffle or a position where it is not blocked at all, and the second position corresponds to a position where the air inlet is at least partially opened or a position where it is fully opened.

[0229] In this way, when identifying different specific cleaning surface materials and specific dirt types, by combining the adjustment of the block and the valve, the cleaning equipment can be flexibly adjusted according to different cleaning environments and dirt types, thereby improving the flexibility of the cleaning equipment. Moreover, by dynamically adjusting the ventilation area of ​​the air inlet and the block height, the suction force can be optimized, thereby protecting the cleaning surface and the cleaning equipment. Especially when dealing with carpets and large particles of dirt, increasing the block height can protect carpet fibers and prevent clogging of the cleaning equipment. In addition, by optimizing the position of the valve and the block, the cleaning equipment can also operate in energy-saving mode, reducing energy consumption and preventing overload of the floor brush motor.

[0230] In some embodiments, the cleaning device can continuously monitor the load of the floor brush motor to adjust the block and the valve based on the load. When the load of the floor brush motor increases to a certain threshold, for example, exceeding 120% of the rated power, the cleaning device can record this state. If this state occurs two or more times in a row, the cleaning device will trigger the corresponding operation, that is, optimize the position of the valve and the block, so as to open the air inlet and / or the dust collection port to reduce the load of the floor brush motor by increasing the air flow. Once the load of the floor brush motor drops to a predetermined lower threshold, for example, less than 120% of the rated power, the movement of the valve and the block is controlled again to close the air inlet and / or the dust collection port, which means that the floor brush motor has returned to an acceptable load range.

[0231] Among them, on carpets of different materials and densities, the load performance of the floor brush motor is different, and accordingly, the state of the dust collection port and the air inlet is also different. For example, on a nylon 6 material with a pile height of 30mm (density of 0.275-0.287g / cm 3) woven carpet, when the load of the floor brush motor is higher than 120% of the rated power, the dust collection port and air inlet are in the open state, and the wool material with a pile height of 6.4mm (density of 0.15g / cm 3 ) on a woven carpet, when the load of the floor brush motor is lower than 120% of its rated power, the dust collection port and the air inlet are both closed.

[0232] Optionally, the ventilation area of ​​the air inlet arranged at the upper part of the adjustment bin arranged at the front part of the floor brush assembly is changed by adjusting the position of the adjustment mechanism; and, when it is identified that the material of a specific cleaning surface is carpet, the ventilation area corresponding to the position where the adjustment mechanism is controlled is greater than the ventilation area corresponding to the position where the adjustment mechanism is controlled when it is identified that the material of the cleaning surface is non-carpet.

[0233] Exemplarily, when the suction force needs to be reduced, such as on a long-pile carpet, the adjustment mechanism is controlled to a position so that the ventilation area of ​​the air inlet is larger, which reduces the vacuum degree inside the floor brush assembly and reduces the resistance to the carpet. When the suction force needs to be increased, such as on a short-pile carpet, the adjustment mechanism is controlled to a position so that the ventilation area of ​​the air inlet is smaller, which increases the vacuum degree inside the floor brush assembly and enhances the adsorption capacity of dust and fine particles.

[0234] In this way, by changing the position of the adjustment mechanism to adjust the ventilation area of ​​the air inlet, the cleaning equipment can provide an ideal cleaning effect on cleaning surfaces of different materials. For cleaning surfaces of different materials, such as carpets or non-carpets, the adaptability of the cleaning equipment is improved by optimizing the ventilation area of ​​the air inlet. In addition, by adjusting the ventilation area of ​​the air inlet and optimizing the vacuum degree inside the floor brush assembly, it is also possible to avoid overloading the floor brush motor, extend the service life of the floor brush assembly, and improve energy efficiency.

[0235] It should also be noted that the above-mentioned automated adjustment mechanism reduces the need for users to manually adjust the floor brush assembly, thereby improving ease of use and comfort.

[0236] Optionally, when it is identified that the material of the specific cleaning surface is carpet, the ventilation area corresponding to the position where the adjustment mechanism is controlled is larger than the ventilation area corresponding to the position where the adjustment mechanism is controlled when it is identified that the material of the cleaning surface is non-carpet, including:

[0237] When it is identified that the pile length of the carpet is greater than or equal to the third threshold, the ventilation area corresponding to the position where the adjustment mechanism is controlled is greater than the ventilation area corresponding to the position where the adjustment mechanism is controlled when it is identified that the material of the cleaning surface is less than the third threshold.

[0238] In the disclosed embodiment, if the length of the carpet's pile is greater than or equal to a third threshold value, the adjustment mechanism is controlled to a position so that the ventilation area of ​​the air inlet is larger, which reduces the vacuum degree inside the floor brush assembly, reduces the resistance to the long pile, and makes the floor brush easier to move on the carpet. At the same time, it can prevent the floor brush motor from overloading and maintain a certain cleaning effect.

[0239] If the pile length of the carpet is less than a third threshold, the adjustment mechanism is controlled to a position so that the ventilation area of ​​the air inlet is relatively small, which increases the vacuum degree inside the floor brush assembly and enhances the adsorption capacity of dust and fine particles on non-carpet surfaces to ensure effective cleaning.

[0240] For example, Figure 7 As shown, when it is detected that the carpet pile length is greater than or equal to the third threshold, the control adjustment mechanism is in the following state: Figure 7 When the carpet pile length is detected to be less than the third threshold, the control adjustment mechanism is in the following position: Figure 8 The position shown in .

[0241] In this way, when the length of the carpet pile is greater than or equal to the third threshold value, the vacuum degree inside the floor brush assembly can be reduced by increasing the ventilation area of ​​the air inlet, thereby preventing the carpet pile from being excessively pulled or damaged, which helps to protect the structural integrity of the carpet while ensuring effective cleaning. For carpets with shorter pile, the vacuum degree inside the floor brush assembly can be increased by reducing the ventilation area of ​​the air inlet, thereby increasing the suction force and enhancing the cleaning ability, ensuring that dust and dirt on the surface and deep layers of the carpet are effectively removed. Therefore, by adjusting the ventilation area of ​​the air inlet according to the length of the pile, and then adjusting the suction force, unnecessary wear or damage to the carpet material can be avoided, thereby extending the service life of the carpet.

[0242] In addition, the above-mentioned automatic adjustment mechanism enables the cleaning device to easily adapt to different types of carpets without the need to manually adjust other settings, thus improving the user experience.

[0243] Optionally, when it is identified that the material of the specific cleaning surface is carpet, controlling the adjustment mechanism to be in the second position includes:

[0244] When it is identified that the material of the specific cleaning surface is carpet, adjusting the position of the stopper to increase the height of the stopper relative to the cleaning surface; and

[0245] After adjusting the position of the stopper to increase the height of the stopper relative to the cleaning surface, the position of the air valve is adjusted to increase the ventilation area of ​​the air inlet.

[0246] For example, Fig. 9A schematic diagram of the position of an adjustment structure is also provided for an embodiment of the present disclosure. When it is identified that the material of the cleaning surface is carpet, the position of the stopper is first adjusted to increase its height relative to the cleaning surface. This step helps to reduce direct contact and wear on the carpet fibers and protect the carpet. After adjusting the position of the stopper, the position of the valve can be further adjusted to increase the ventilation area of ​​the air inlet. This step further increases the vacuum degree inside the brush assembly, thereby reducing the influence of suction on the carpet, preventing the carpet fibers from being excessively pulled, and ensuring an appropriate cleaning effect. At this time, the adjustment mechanism is in a state as follows: Fig. 9 Position shown.

[0247] In some embodiments, when it is detected that the cleaning surface is a carpet, a specific adjustment procedure is started, that is, before adjusting the position of the valve, the height of the block is first adjusted. The position of the block is adjusted to increase its height relative to the cleaning surface. This adjustment reduces the contact and resistance of the block to the carpet fluff, making it easier to move the floor brush assembly on the carpet. After the block adjustment is completed, the position of the valve is further adjusted to increase the ventilation area of ​​the air inlet. The ventilation area is increased to reduce the vacuum degree inside the floor brush assembly, further reducing the adsorption force on the carpet, preventing the floor brush from being difficult to move on the carpet or overloading the floor brush motor.

[0248] It is understandable that after increasing the height of the block relative to the cleaning surface, the vacuum degree inside the floor brush assembly will also adaptively decrease. Further adjusting the valve position to increase the ventilation area of ​​the air inlet can reduce the vacuum degree inside the floor brush assembly even more.

[0249] Optionally, when it is identified that the material of the specific cleaning surface is carpet and there is first type of dirt on the carpet, the position of the block is adjusted to increase the height of the block relative to the cleaning surface; and after adjusting the position of the block to increase the height of the block relative to the cleaning surface, the position of the valve is adjusted to increase the ventilation area of ​​the air inlet.

[0250] Therefore, by adjusting the height of the block, the movement of the floor brush assembly on the carpet is smoother, direct contact with the carpet fibers is reduced, damage and wear are prevented, and the service life of the carpet is extended. The valve is further adjusted to increase the ventilation area of ​​the air inlet, further reducing the vacuum degree inside the floor brush assembly, reducing the suction effect on the carpet, and helping to avoid pulling and damaging the carpet fluff, ensuring the cleaning effect while protecting the carpet. In this way, by adjusting the block first and then adjusting the valve, the cleaning equipment can provide better cleaning effect on the carpet, while avoiding excessive adsorption of the carpet, reducing subsequent maintenance costs.

[0251] It should be understood that the movement of the block and the movement of the valve can be independent of each other or can be associated. Specifically, in the adjustment mechanism, a control mechanism for the block and a control mechanism for the valve can be respectively provided to independently control the height of the block from the cleaning surface (i.e., the height of the dust collecting port) and the ventilation area of ​​the air inlet. In the adjustment mechanism, a control mechanism can also be provided to enable the block and the valve to be linked. For example, in the above embodiment, the control mechanism can be designed to control the linkage of the block and the valve, wherein the movement of the block is first controlled to increase the height of the block relative to the cleaning surface, and after the block moves to the maximum height, the movement of the valve is controlled to increase the ventilation area of ​​the air inlet. Of course, the control mechanism can also be designed to control the linkage of the valve and the block, wherein the movement of the valve is first controlled and then the movement of the block is controlled.
