Description
Technical Field
[0001] This invention relates to the field of sensor detection technology, and in particular to an intelligent cleaning method for cleaning equipment. Background Technology
[0002] Currently, wet cleaning equipment such as floor scrubbers and sweepers on the market cannot accurately identify and classify dirt. Different types of dirt require the same amount of water, and some minor dirt can sometimes be cleaned with less water, thus failing to achieve the goal of saving water. Users who always use a large amount of water to clean all dirt will need to refill the floor scrubber or sweeper after a short period of use, which greatly affects the user experience.
[0003] Therefore, precise control of water output and water conservation are features that current sweeping and scrubbing machines on the market cannot achieve. Summary of the Invention
[0004] (a) Technical problems to be solved
[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an intelligent cleaning method for cleaning equipment, which solves the technical problems of the prior art being unable to accurately identify and classify dirt, as well as the varying cleaning flow rates and durations for different types of dirt.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, the main technical solutions adopted by the present invention include:
[0008] In a first aspect, embodiments of the present invention provide an intelligent cleaning method for a cleaning device, characterized in that the cleaning device includes a floor brush assembly for contacting a surface to be cleaned, a liquid supply assembly for supplying cleaning liquid to the surface to be cleaned and / or the floor brush assembly, a humidity detection device, and a processing module electrically connected to the floor brush assembly and the humidity detection device, wherein the floor brush assembly includes a cleaning brush, and the humidity detection device is used to acquire the humidity value of the cleaning brush, and the intelligent cleaning method includes:
[0009] The processing module acquires the working mode of the cleaning equipment and receives the first humidity value of the cleaning brush from the humidity detection device.
[0010] The processing module obtains the status of the floor brush component based on the working mode of the cleaning equipment and the first humidity value;
[0011] The processing module controls the flow rate of the liquid supply component based on the status of the floor brush component.
[0012] Optionally,
[0013] A humidity threshold is determined based on the humidity characteristics of the cleaning brush. The humidity threshold includes a dry threshold, a wet threshold, and a dirty threshold that increase sequentially. The processing module determines whether the cleaning brush is in a dry state, a wet state, or a dirty state based on the first humidity value and the humidity threshold.
[0014] The working modes of the cleaning equipment include: surface cleaning mode, self-cleaning mode, and self-drying mode;
[0015] The status of the floor brush component includes:

[0017] The self-cleaning mode is in dry state, the self-cleaning mode is in wet state, and the self-cleaning mode is in dirty state.
[0018] The dry state of the self-drying mode and the wet state of the self-drying mode.
[0019] Optionally, the method by which the processing module controls the flow rate of the liquid supply component based on the state of the floor brush component includes:
[0020] When the floor brush assembly is in surface cleaning mode, it is determined whether the first humidity value is greater than the wetting threshold.
[0021] If the first humidity value is greater than the humidification threshold, then it is determined whether the first humidity value is greater than the dirt threshold. If so, the flow rate of the liquid supply component is determined to be the first high flow rate; otherwise, the flow rate of the liquid supply component is determined to be the first low flow rate.
[0022] If the first humidity value is less than or equal to the humidification threshold, then it is determined whether the first humidity value is greater than the drying threshold. If so, the flow rate of the liquid supply component is determined to be the first medium flow rate; otherwise, the flow rate of the liquid supply component is determined to be the second high flow rate.
[0023] Optionally, it also includes:
[0024] The processing module monitors the duration of the first medium flow rate or the second high flow rate. If the duration exceeds the set first duration, the humidity detection device measures the second humidity value of the cleaning brush. The processing module re-determines the state of the floor brush assembly based on the second humidity value and controls the flow rate of the liquid supply assembly based on the state of the floor brush assembly.
[0025] Alternatively, the processing module monitors the duration of the first flow rate. If the duration exceeds the set first duration, the humidity detection device measures the second humidity value of the cleaning brush. When the second humidity value is greater than the humidification threshold, the flow rate of the liquid supply component is adjusted to a first low flow rate.

[0027] When the floor brush assembly is in self-cleaning mode, it is determined whether the first humidity value is within the clean humidity range. If so, it is determined that the floor brush assembly has completed self-cleaning. Otherwise, the floor brush assembly continues to self-clean, and the humidity of the cleaning brush is continuously monitored to ensure that it is within the clean humidity range until the floor brush assembly has completed self-cleaning.
[0028] Optionally, when the floor brush assembly is in self-cleaning mode, the processing module obtains the duration for which the humidity of the cleaning brush is lower than the lower limit of the clean humidity range. When the duration is greater than a predetermined time, the processing module issues a reminder signal to the user to replace the cleaning brush.
[0029] Optionally, the intelligent cleaning method includes a cleaning brush drying control method, which includes:
[0030] When the floor brush assembly is in self-drying mode, the humidity detection device acquires the drying humidity value of the cleaning brush and determines whether the drying humidity value is less than the drying humidity threshold. If so, the drying mode is turned off; otherwise, drying continues and the drying humidity value is continuously monitored until the drying humidity value is less than the drying humidity threshold; and / or
[0031] The cleaning device includes a dirt sensor capable of sensing dirt information from the cleaning brush or the surface to be cleaned. The processing module obtains the status of the floor brush assembly based on the operating mode of the cleaning device, the first humidity value, and the dirt information; and / or
[0032] The working modes of the cleaning equipment also include a heavy dirt mode, and the processing module controls the working mode of the cleaning equipment according to the status of the floor brush assembly.
[0033] Optionally,
[0034] The cleaning brush is detachably installed on the floor brush assembly. The state of the floor brush assembly includes a state where the cleaning brush is missing. The processing module determines whether the floor brush assembly is in the state where the cleaning brush is missing based on the working mode of the cleaning equipment, the start-up time of the working mode, and the first humidity value.
[0035] Optionally, the cleaning brush is a detachable roller brush mounted on the floor brush assembly. The floor brush assembly includes a floor brush housing, a detachable roller brush cover mounted on the floor brush housing, and a drive motor for driving the roller brush to rotate. The roller brush cover and the floor brush housing together form a roller brush cavity. The roller brush is at least partially mounted in the roller brush cavity. The state of the floor brush assembly includes a floor brush accessory installation state. The method by which the processing module determines the floor brush accessory installation state includes:
[0036] After the cleaning equipment is started, the processing module receives the first current detection value of the drive motor and the first humidity value fed back in real time by the humidity detection device.
[0037] The processing module determines the installation status of the floor brush accessory based on the start-up time of the cleaning equipment, the first current detection value, and the first humidity value.
[0038] Optionally, the method by which the processing module determines the state of the floor brush component includes:
[0039] When the cleaning device is in the surface cleaning state or self-cleaning state, and the start-up time of the surface cleaning is longer than the predetermined duration, the state of the floor brush assembly is determined according to the following steps:
[0040] When the first humidity value is less than the first preset humidity value and the first current detection value is less than the first preset current detection value, the state of the floor brush assembly is that neither the roller brush cover nor the roller brush is installed.
[0041] When the first humidity value is greater than the first preset humidity value and less than the second preset humidity value, and the first current detection value is greater than the first preset current detection value, the state of the floor brush assembly is that the roller brush cover is not installed but the roller brush is installed.
[0042] When the first humidity value is greater than the first preset humidity value and less than the second preset humidity value, and the first current detection value is less than the first preset current detection value, the state of the floor brush assembly is that the roller brush is not installed but the roller brush cover is installed.
[0043] When the first humidity value is greater than the second preset humidity value, and the first current detection value is greater than the first preset current detection value, the state of the floor brush assembly is that both the roller brush and the roller brush cover are installed.

[0067] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0068] This invention proposes an intelligent cleaning method for cleaning equipment. By monitoring changes in humidity on the cleaning brush to distinguish the type of stains and intelligently adjusting the water pump output, it solves the problems of not being able to accurately identify and classify dirt, as well as the issue of varying water flow and runtime for different types of dirt. This achieves precise and intelligent water control and improved water lifespan for cleaning equipment such as sweepers and floor scrubbers. For relatively clean floors, the water pump output can be reduced, thus saving water.
[0069] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.
[0070] Example 1
[0071] The cleaning device of this embodiment includes: a floor brush assembly for contacting the surface to be cleaned, a liquid supply assembly for supplying cleaning liquid to the surface to be cleaned and / or the floor brush assembly, a humidity detection device, and a processing module electrically connected to the floor brush assembly and the humidity detection device. The floor brush assembly includes a cleaning brush, and the humidity detection device is used to acquire the humidity value of the cleaning brush. Figure 1 As shown, this embodiment provides an intelligent cleaning method for cleaning equipment, the specific implementation of which includes the following steps:
[0072] 101. The processing module acquires the working mode of the cleaning equipment and receives the first humidity value of the cleaning brush fed back by the humidity detection device;
[0073] Specifically, the working modes of the cleaning equipment mentioned in this embodiment include: surface cleaning mode, self-cleaning mode, and self-drying mode.
[0074] 102. The processing module obtains the status of the floor brush assembly based on the working mode of the cleaning equipment and the first humidity value;
[0075] Specifically, this embodiment can determine the humidity threshold based on the humidity characteristics of the cleaning brush in the floor brush assembly. The humidity values corresponding to cleaning brushes used on different cleaning devices will differ under dry, wet, and dirty conditions (including slightly dirty and heavily dirty conditions). Therefore, it is necessary to determine an appropriate humidity threshold based on the humidity characteristics of different cleaning brushes. The specific number of humidity thresholds can be appropriately selected according to actual needs. In this embodiment, the humidity thresholds include a successively increasing dry threshold, wet threshold, and dirty threshold. The processing module can then determine whether the cleaning brush in the floor brush assembly is in a dry, wet, or dirty state based on the first humidity value and the humidity thresholds.
[0076] For example, when the cleaning equipment is in surface cleaning mode, the first humidity value of the cleaning brush fed back by the humidity detection device can correspond to the dry state, wet state, and dirty state of the surface cleaning mode.
[0077] When the cleaning equipment is in self-cleaning mode, the first humidity value of the cleaning brush fed back by the humidity detection device can correspond to the wet state and the dirt state of the self-cleaning mode.
[0078] When the cleaning equipment is in self-drying mode, the first humidity value of the cleaning brush fed back by the humidity detection device can correspond to the dry state and the wet state of the self-drying mode.
[0079] Furthermore, the dirt state of the surface cleaning mode includes a slightly dirty state and a heavily dirty state.
[0080] 103. The processing module controls the flow rate of the liquid supply component according to the status of the floor brush component.
[0081] Specifically, such as Figure 2 and Figure 3 As shown, Figure 2 and Figure 3 The above steps 103 will be explained in detail.
[0082] For example, in Figure 2 In the process, when the cleaning equipment is in surface cleaning mode, 103-1, it is determined whether the first humidity value is greater than the humidity threshold.
[0083] 103-2. If the humidity value is greater than the moisture threshold, it is necessary to continue to determine whether the first humidity value is greater than the dirt threshold.
[0084] In this embodiment, the threshold can be predetermined, for example, determined based on the humidity characteristics of the cleaning brush as described above.
[0085] 103-3. If the flow rate is greater than the dirt threshold, the flow rate of the liquid supply component is determined to be the first high flow rate.
[0086] Based on the fact that the cleaning equipment is in surface cleaning mode and the first humidity value is greater than the dirt threshold, the processing module can infer that the current state of the floor brush component is a heavily dirty state in surface cleaning mode. The cleaning ability can be improved by applying a large amount of cleaning liquid to the surface to be cleaned, thereby effectively cleaning the dirt. In particular, dirt with a darker color, such as soy sauce, requires a large amount of cleaning liquid to clean. The flow rate of the liquid supply component is determined to be the first high flow rate.
[0087] 103-4. If, in steps 103-1 and 103-2 above, the first humidity value is greater than the humidification threshold and less than or equal to the dirt threshold, then the flow rate of the liquid supply component is determined to be the first low flow rate.
[0088] Based on the fact that the cleaning equipment is in surface cleaning mode and the first humidity value is greater than the wetting threshold and less than or equal to the dirt threshold, the processing module can infer that the current state of the floor brush assembly is the wet state of surface cleaning mode. At this time, the surface to be cleaned corresponding to the surface cleaning equipment is relatively clean and the cleaning brush has appropriate humidity. There is no need to increase the water volume, and the flow rate of the liquid supply assembly is determined to be the first low flow rate.
[0089] When the flow rate of the liquid supply component is at the first high flow rate or the first low flow rate for a certain period of time, the control module can reacquire the first humidity value, that is, return to step 103-1. When the cleaning equipment is in the surface cleaning mode, the above steps can be repeated until the cleaning of the surface to be cleaned is completed.
[0090] 103-5. If the first humidity value in step 103-1 above is less than or equal to the humidity threshold, such as... Figure 2 The judgment process shown on the right side is as follows: at this time, it is determined whether the first humidity value is greater than the dryness threshold.
[0091] 103-6. If the first humidity value is greater than the drying threshold, the flow rate of the liquid supply component is the first medium flow rate; otherwise, the flow rate of the liquid supply component can be the second high flow rate.
[0092] Based on the fact that the cleaning equipment is in surface cleaning mode and the first humidity value is greater than the drying threshold and less than or equal to the wetting threshold, the processing module can infer that the current state of the floor brush assembly is a slightly dirty state in surface cleaning mode. The flow rate of the liquid supply assembly is the first medium flow rate. The cleaning brush is wetted by the first medium flow rate to improve the cleaning ability for slightly dirty surfaces.
[0093] Based on the fact that the cleaning equipment is in surface cleaning mode and the first humidity value is less than the drying threshold, the processing module can infer that the current state of the floor brush assembly is the dry state of surface cleaning mode. At this time, the cleaning brush is not wet enough and a large amount of cleaning liquid is needed to quickly wet the cleaning brush so that it can enter the fully wet state for cleaning more quickly. The flow rate of the liquid supply component is the second flow rate.
[0094] In addition, in this embodiment, when the processing module monitors the duration of the first medium flow rate or the second high flow rate, if the duration exceeds the set first duration, the humidity detection device measures the second humidity value of the cleaning brush, the processing module re-determines the state of the floor brush assembly based on the second humidity value, and controls the flow rate of the liquid supply assembly based on the state of the floor brush assembly, that is, returns to step 103-1. When the cleaning equipment is in the surface cleaning mode, the above steps can be repeated until the cleaning of the surface to be cleaned is completed.
[0095] Alternatively, in another scenario, the processing module monitors the duration of the first flow rate. If the duration exceeds a set first duration, the humidity detection device measures a second humidity value of the cleaning brush. When the second humidity value is greater than the moisture threshold, it can be determined that the cleaning of minor dirt is complete, and the flow rate of the liquid supply component is adjusted to a first low flow rate. When the flow rate of the liquid supply component is a second high flow rate, the processing module can monitor the duration of the second high flow rate. If the duration exceeds a set first duration, the humidity detection device measures a second humidity value of the cleaning brush. The processing module then re-determines the state of the floor brush component based on the second humidity value and controls the flow rate of the liquid supply component based on the state of the floor brush component, i.e., returns to step 103-1. When the cleaning equipment is in surface cleaning mode, the above steps can be repeated until the cleaning of the surface to be cleaned is completed.
[0096] The first low flow rate of the liquid supply component described above is less than the first medium flow rate, the first medium flow rate is less than the first high flow rate, and the first medium flow rate is less than the second high flow rate. The first high flow rate and the second high flow rate can be equal or unequal, and appropriate design selection can be made according to the usage requirements of the cleaning equipment.
[0097] exist Figure 3 In the middle, the processing module can activate the self-cleaning mode of the floor brush assembly, such as... Figure 3As shown on the left, 103-11, when the local brush component is in self-cleaning mode, determine whether the first humidity value is within the clean humidity range;
[0098] 103-12. If the first humidity value is within the clean humidity range, it is determined that the floor brush assembly has completed self-cleaning. At this time, it can be inferred that the current state of the floor brush assembly is the wet state of the self-cleaning mode.
[0099] 103-13. If the first humidity value is not within the clean humidity range, it can be inferred that the current state of the floor brush assembly is a dirty state in self-cleaning mode. The floor brush assembly continues to self-clean and continues to monitor whether the humidity of the cleaning brush is within the clean humidity range until the floor brush assembly completes self-cleaning.
[0100] Furthermore, the processing module obtains the duration for which the humidity of the cleaning brush is lower than the lower limit of the clean humidity range. When the duration is greater than a predetermined time (e.g., a seconds, 3 to 20 minutes, etc.), the processing module sends a reminder signal to the user to replace the cleaning brush.
[0101] It is understandable that the humidification thresholds in steps 103-11 to 103-13 above are the pure humidity values of a clean cleaning brush, because there is a large difference between the humidification threshold corresponding to a clean cleaning brush and the humidification threshold corresponding to a dirty brush, and the mentioned duration can be appropriately selected according to the characteristics of the cleaning brush, for example, between 10 minutes and 15 minutes.
[0102] After completing the self-cleaning mode, the cleaning brush remains wet. If the user does not remove the brush and allow it to dry promptly, the brush will remain damp for an extended period, potentially causing it to develop an unpleasant odor, negatively impacting the user experience and shortening its lifespan. Therefore, it is preferable to dry the cleaning brush after self-cleaning is complete.
[0103] Furthermore, intelligent cleaning methods include cleaning brush drying control methods, such as... Figure 3 As shown on the right, when the ground brush assembly is in self-drying mode, the humidity detection device obtains the drying humidity value of the cleaning brush and determines whether the drying humidity value is less than the drying humidity threshold. If so, the drying mode is turned off; otherwise, drying continues and the drying humidity value is continuously monitored until the drying humidity value is less than the drying humidity threshold.
[0104] At this time, the status of the floor brush assembly includes the dry state in self-drying mode and the wet state in self-drying mode. When the drying humidity value is greater than the drying humidity threshold, the processing module infers that the floor brush assembly is in the wet state of the sub-drying mode, and drying is not complete and needs to continue; when the drying humidity value is less than the drying humidity threshold, the processing module infers that the floor brush assembly is in the dry state of the drying mode, and drying is not complete.
[0105] In addition, the various humidity thresholds mentioned in this embodiment can be set manually, or calculated based on data such as usage time and usage habits collected by the cloud platform; they can also be determined based on the usage cycle of the floor brush component and the current dirt image.
[0106] For example, the aforementioned dirt threshold is determined by the time the floor brush assembly is used, the current state of the floor brush assembly, and the dry, wet, lightly dirty, and heavily dirty values of the floor brush assembly surface. In the above embodiments, high, medium, and low flow rates are all preset flow rates. After the processing module determines the flow rate, it can generate a flow adjustment command for the flow control component, causing the flow control component to execute the corresponding flow rate according to the water volume adjustment command.
[0107] In this embodiment, the processing mode can determine that the floor brush assembly is in surface cleaning mode and at the first high flow rate. Then, the duration of the first high flow rate is monitored, and the cleaning method of the surface to be cleaned is selected according to the duration of the monitored first high flow rate.
[0108] For example, the system can address different levels of dirt based on the cleaning brush's humidity level and provide corresponding treatment methods. These include, but are not limited to, adjusting the water pump flow rate, adding or removing cleaning agents to enhance the machine's cleaning ability while adjusting the water pump flow rate, or turning high-temperature steam on or off. Furthermore, voice prompts can be provided to the user simultaneously with the cleaning agent or steam switch. The cleaning agent cleaning mode and high-temperature steam cleaning mode can be used as heavy-duty cleaning modes for surfaces with severe dirt. Additionally, heavy-duty cleaning modes may also include hot water cleaning mode and foam cleaning mode.
[0109] The cleaning device may also include a dirt sensor, which can sense dirt information of the cleaning brush or the surface to be cleaned. The processing module obtains the status of the floor brush assembly based on the working mode of the cleaning device, the first humidity value and the dirt information, thereby further improving the dirt sensing accuracy.
[0110] The method in this embodiment can effectively save water consumption for cleaning equipment, while improving the user experience and extending the service life of the cleaning equipment.
[0111] Example 2
[0112] This embodiment also provides a cleaning device, which includes a humidity detection device and a processing module. The floor brush assembly and the humidity detection device are electrically connected to the processing module, and the processing module can execute the steps of the intelligent cleaning method of the cleaning device described in the above embodiment.
[0113] The cleaning equipment in this embodiment can be a sweeper or a floor scrubber, etc., and is not limited to it in this embodiment; it can be selected according to actual needs. In addition, the cleaning brush in this embodiment is a detachable roller brush installed on the floor brush assembly. The floor brush assembly may include a floor brush housing, a detachable roller brush cover installed on the floor brush housing, and a drive motor for driving the roller brush to rotate. Typically, the humidity detection device can be placed near the roller brush, for example, in contact with the surface of the floor brush, or at a distance of -1 to 2 mm from the surface of the floor brush.
[0114] Specifically, the humidity detection device mentioned in this embodiment includes the following detection unit: Figure 4 As shown, Figure 4 The diagram shows metal electrode 13, where the detection unit consists of two metal electrodes. Changes in the capacitance of the metal electrodes reflect changes in the humidity value near them. To ensure the accuracy of the humidity detection device, interference from moisture must be avoided, as well as mechanical damage, oxidation, and rust, ensuring its normal service life. Preferably, the detection unit is sealed to isolate it from external moisture; therefore, it is encased in a plastic shell 12. The method of encasing the detection unit in the plastic shell 12 can be appropriately selected according to actual needs. For example, the detection unit can be encapsulated inside the plastic shell after the plastic shell is manufactured separately. Preferably, the detection unit and the plastic shell are injection molded using insert molding, as follows: Figure 5 and Figure 6 As shown. Among them, Figure 5 The metal electrode 13 and the plastic housing 12 after insert injection molding are shown; Figure 6 The plastic casing 12 is shown.
[0115] In addition, to improve the measurement accuracy of the humidity detection device and better distinguish the humidity range of the roller brush, the humidity detection device should be placed as close to the roller brush as possible. For example, the plastic shell covering the humidity detection device should be close to the roller brush, with the distance controlled between -1 and 2 mm. Figure 7 and Figure 8 As shown. Among them, Figure 7 The humidity detection device 11, the floor brush housing 17, and the rear wheel 15 are shown. Figure 8 The humidity detection device 11 and the roller brush 14 are shown close to the roller brush.
[0116] The humidity detection device mentioned in this embodiment can directly contact the roller brush, which is closer and provides more accurate monitoring data.
[0117] Example 3
[0118] This embodiment takes determining the installation status of a floor brush accessory as an example. The cleaning brush is detachably installed on the floor brush assembly. The status of the floor brush assembly includes a state where the cleaning brush is missing. The processing module determines whether the floor brush assembly is in the state where the cleaning brush is missing based on the working mode of the cleaning equipment, the start-up time of the working mode, and the first humidity value.
[0119] Further, the cleaning brush is a detachable roller brush mounted on the floor brush assembly. The floor brush assembly includes a floor brush housing, a detachable roller brush cover mounted on the floor brush housing, and a drive motor for rotating the roller brush. The roller brush cover and the floor brush housing together form a roller brush cavity, and the roller brush is at least partially mounted in the roller brush cavity. The state of the floor brush assembly includes the floor brush accessory installation state. The method by which the processing module determines the floor brush accessory installation state includes:
[0120] S1. After the cleaning equipment is started, the processing module receives the first current detection value of the drive motor and the first humidity value fed back in real time by the humidity detection device.
[0121] Specifically, the humidity detection device reflects changes in the ambient humidity by measuring changes in the capacitance of the metal electrode. At the same time, changes in the surrounding medium will also affect the detection value of the humidity detection device. This principle can be used to determine whether the floor brush accessories are installed.
[0122] S2. The processing module determines the installation status of the floor brush accessory based on the start-up time of the cleaning equipment, the first current detection value, and the first humidity value.
[0123] Steps S1 and S2 here can be performed before step 101 in the above embodiment one, so that the process of adjusting the water volume is performed after confirming that the floor brush accessories are installed in place. Alternatively, steps S1, S2 and step 101 in the above embodiment one can be performed simultaneously, and an alarm can be issued in time if the floor brush accessories are found to be missing.
[0124] For example, in this embodiment, the following situations are considered based on the possible states of the floor brush:
[0125] After the machine has been running for a period of time and the water pump is supplying water normally, the humidity detection device detects a first humidity value. If the first humidity value is less than a first preset humidity value, and the first current detection value of the drive motor is less than the first preset current detection value of the drive motor, then it is determined that the floor brush assembly is in a state where neither the roller brush cover 16 nor the roller brush 14 is installed, as follows: Figure 9 As shown, where, Figure 9 The humidity detection device 11 close to the roller brush, the brush housing 17, the drive motor 18, and the rear wheel 15 are shown.
[0126] If, after the machine has been running for a period of time and the water pump is supplying water normally, if the first humidity value of the humidity detection device is greater than the first preset humidity value and less than the second preset humidity value, and at the same time the first current detection value of the drive motor is greater than the first preset current detection value of the drive motor, then it is determined that the floor brush assembly is in a state where the roller brush cover 16 is not installed but the roller brush 14 is installed. Figure 10 As shown, where, Figure 10 The roller brush 14, the floor brush housing 17, and the rear wheel 15 are shown.
[0127] If, after the machine has been running for a period of time and the water pump is supplying water normally, if the first humidity value of the humidity detection device is greater than the first preset humidity value and less than the second preset humidity value, and at the same time the first current detection value of the drive motor is less than the first preset current detection value of the drive motor, then it is determined that the floor brush assembly is in a state where the roller brush 14 is not installed but the roller brush cover 16 is installed. Figure 11 As shown, where, Figure 11 The floor brush housing 17, rear wheel 15, drive motor 18, and roller brush cover 16 are shown.
[0128] If, after the machine has been running for a period of time and the water pump is supplying water normally, if the first humidity value of the humidity detection device is greater than the second preset humidity value, and the first current detection value of the drive motor is greater than the first preset current detection value of the drive motor, then it is determined that the floor brush assembly is in a state where both the roller brush 14 and the roller brush cover 16 are installed. Figure 12 As shown, where, Figure 12 The floor brush housing 17, rear wheel 15, roller brush cover 16, and roller brush 14 are shown.
[0129] In addition, the test threshold and detection threshold mentioned in this embodiment can be set manually or calculated by the cloud platform based on data such as the roller brush usage time and the ground brush current. The motor detection value mentioned is obtained by detecting the motor current.
[0130] According to the steps of the above embodiments, the method of combining the current value of the drive motor with the test value of the humidity detection device can distinguish the status of the floor brush and remind the user to install the roller brush cover or roller brush.
[0131] The method in this embodiment can effectively determine whether the roller brush is in place, making it easier to remind users that the roller brush is missing and improving the user experience.
