[0004] Cleaning equipment is now widely used in daily life, including vacuum cleaners and handheld floor scrubbers. During use, the cleaning equipment stores a mixture of sewage and dirt in the gas-solid-liquid separation chamber of the sewage tank. The sewage in the mixture is separated in the gas-solid-liquid separation chamber and then enters the sewage tank's waste liquid chamber.

[0005] In related technologies, the low separation efficiency of the gas-solid-liquid separation chamber results in a large amount of unseparated wastewater remaining within the chamber. During use, the reciprocating movement of the cleaning equipment can easily cause agitation of the wastewater within the chamber, which can be sucked into the suction assembly, causing it to fail. This severely impacts the assembly's performance and can even shorten its lifespan.

[0036] The following describes in detail embodiments of the present application, and the embodiments described with reference to the accompanying drawings are exemplary.

[0037] The following describes a control method for a cleaning device 100 according to an embodiment of the present application with reference to Figures 1 to 10 , which can effectively improve the efficiency of wastewater separation, thereby preventing the suction assembly 20 from easily sucking in wastewater and causing it to fail. For example, the cleaning device 100 can be a vacuum cleaner, a handheld floor scrubber, or the like.

[0038] As shown in Figures 1 to 10, according to the control method of the cleaning device 100 of the first embodiment of the present application, the cleaning device 100 includes a sewage tank 10 and a suction component 20, the sewage tank 10 has a solid-liquid separation chamber 11 and a sewage holding chamber 12, the solid-liquid separation chamber 11 and the sewage holding chamber 12 are connected, the suction component 20 is connected to the solid-liquid separation chamber 11 to provide power for dirt to enter the solid-liquid separation chamber 11, and the suction component 20 is also connected to the sewage holding chamber 12 to provide power for sewage to enter the sewage holding chamber 12 from the solid-liquid separation chamber 11; wherein the control method includes: when the suction component 20 is started, the suction component 20 sucks air in the sewage holding chamber 12 to drive the sewage in the solid-liquid separation chamber 11 to flow into the sewage holding chamber 12. With such a configuration, the suction force of a suction component 20 is utilized to achieve conventional dirt collection work on the one hand, and on the other hand, the suction component 20 provides suction force to the sewage tank 10, which can prevent water from being sucked into the suction component 20 when the cleaning device 100 lies down at a certain angle to work.

[0039] Specifically, the sewage tank 10 is used to store sewage and dirt generated by the cleaning equipment 100 when performing cleaning work. The sewage tank 10 is mainly composed of a solid-liquid separation chamber 11 and a sewage holding chamber 12. The solid-liquid separation chamber 11 serves to separate solid dirt and liquid sewage in the dirt, and the sewage holding chamber 12 serves to hold sewage. The solid-liquid separation chamber 11 and the sewage holding chamber 12 are connected to each other, so that the sewage in the solid-liquid separation chamber 11 can be guided into the sewage holding chamber 12.

[0040] Among them, the solid-liquid separation chamber 11 is connected to the suction component 20, and the suction component 20 has a sewage suction pipe 30, through which the air in the solid-liquid separation chamber 11 can be sucked, and the solid-liquid separation chamber 11 forms a negative pressure environment, so that the dirt on the ground can be sucked into the solid-liquid separation chamber 11 under the action of negative pressure; the cleaning device 100 also has a suction channel 40, and a suction inlet 41 and a suction outlet 42 are formed at both ends of the suction channel 40, and the suction inlet 41 and the suction outlet 42 are respectively connected to the dirty liquid holding chamber 12 and the suction component 20, and the suction component 20 can The air in the waste liquid holding chamber 12 is sucked out, and a negative pressure environment is formed in the waste liquid holding chamber 12. In this way, the waste water in the solid-liquid separation chamber 11 can be quickly guided into the waste liquid holding chamber 12 under the action of the negative pressure, thereby accelerating the waste water separation speed in the solid-liquid separation chamber 11, making it difficult for the waste water in the solid-liquid separation chamber 11 to accumulate. Moreover, due to its own gravity, the waste water that falls into the waste liquid holding chamber 12 can move upward along the suction channel 40 under the action of the negative pressure of the suction assembly 20. The path required to overcome the gravity work is longer, thereby preventing the waste water from easily entering the suction assembly 20 and causing its failure. Moreover, when the cleaning device 100 is lying down at a certain angle to work, although the liquid level in the dirty liquid holding chamber 12 will change, causing the liquid to be closer to the suction component 20, under the action of the suction airflow in the suction channel 40, the dirty water is sucked in the direction away from the solid-liquid separation chamber 11, providing resistance for the sewage to flow back to the solid-liquid separation chamber 11, so that the liquid will not be accidentally sucked into the suction component 20 due to the lying operation of the cleaning device 100, ensuring that the cleaning device 100 can work normally. The cleaning device 100 can adapt to the cleaning needs of different household scenarios. It can not only perform normal floor cleaning, but also lie down at a larger angle to clean low areas such as under the bed or under the table.

[0041] The following is a timing diagram of the startup of the cleaning device 100 of an embodiment. In this embodiment, the cleaning device 100 is a floor scrubber, and the suction component 20 includes a fan. The floor scrubber includes components that need to be powered on and controlled, such as a fan, a display screen, and an indicator light. For the sake of simplicity, in the following description, the components that need to be powered on and controlled except for the fan are collectively referred to as other peripherals. When the floor scrubber is turned on, the other peripherals of the floor scrubber are powered on and run. In addition, when the floor scrubber is turned on, the fan is also powered on and run to provide power for the dirt to enter the solid-liquid separation chamber 11 through the sewage suction pipe 30. At the same time, when the floor scrubber is turned on, the fan is powered on and run to provide power for the sewage to enter the sewage holding chamber 12 from the solid-liquid separation chamber 11. When the fan is powered on, dirt begins to enter the solid-liquid separation chamber 11. After the dirt enters the solid-liquid separation chamber 11, the suction component 20 can be controlled to provide driving force for the sewage in the dirt, so that the sewage in the dirt enters the sewage holding chamber 12 with higher efficiency, thereby preventing sewage from accumulating in the solid-liquid separation chamber 11.

[0042] In the above technical solution, when the suction assembly 20 is activated, it can quickly and efficiently separate the wastewater from the wastewater as it enters the solid-liquid separation chamber 11. This prevents wastewater from accumulating within the solid-liquid separation chamber 11, thereby preventing wastewater from entering the suction assembly 20 and causing it to fail, thus extending the service life of the suction assembly 20. Furthermore, this control method can prevent the suction assembly 20 from sucking wastewater outside the cleaning device 100, thereby ensuring the cleaning effectiveness of the cleaning device 100.

[0043] Therefore, by designing this control method, the sewage separation efficiency can be effectively improved, thereby effectively preventing the accumulation of sewage in the solid-liquid separation chamber 11, and further avoiding the problem that the suction component 20 easily sucks in sewage and causes its failure.

[0044] According to some optional embodiments of the present application, as shown in combination with Figures 3 and 9, the cleaning device 100 includes a floor brush assembly 50, and the control method further includes that when the suction assembly 20 is started, the suction assembly 20 simultaneously provides a negative pressure airflow to drive the dirt to be sucked from the floor brush assembly 50 and flow into the solid-liquid separation chamber 11. Specifically, the floor brush assembly 50 uniformly collects dirt on the cleaning surface, and the dirt is sucked into the solid-liquid separation chamber 11 under the action of the negative pressure formed by the suction of the air by the suction assembly 20, thereby achieving the cleaning effect of sucking the dirt on the floor brush assembly 50 into the sewage tank 10.

[0045] According to some optional embodiments of the present application, the airflow driven by the suction assembly 20 extends at least partially in a direction away from the sewage tank 10. This facilitates the suction assembly 20 to quickly create a negative pressure environment in the solid-liquid separation chamber 11 and the sewage holding chamber 12 in the sewage tank 10, thereby improving the suction efficiency of the suction assembly 20.

[0046] According to some optional embodiments of the present application, as shown in conjunction with Figures 3 and 10 , the cleaning device 100 includes a flow-disrupting structure 60. The airflow within the dirty liquid holding chamber 12 passes through the flow-disrupting structure 60 and reaches the suction assembly 20. Specifically, when the suction assembly 20 sucks air from the dirty liquid holding chamber 12, the dirty liquid carried in the sucked air is blocked, thereby increasing the flow resistance of the dirty liquid before entering the suction assembly 20. This prevents the dirty liquid in the dirty liquid holding chamber 12 from easily entering the suction assembly 20 under the suction force of the suction assembly 20, thereby causing failure, thereby extending the service life of the cleaning device 100.

[0047] According to some optional embodiments of the present application, in combination with Figures 1 to 3, a liquid level detector is provided in the solid-liquid separation chamber 11 for detecting the liquid level in the solid-liquid separation chamber 11, and the control method further includes: obtaining liquid level information detected by the liquid level detector; when the liquid level indicated by the liquid level information is within any target liquid level range of a plurality of target liquid level ranges, controlling the suction component 20 to operate according to the suction component 20 power corresponding to the target liquid level range; wherein the ranges of the plurality of target liquid levels do not overlap with each other, and the range of the target liquid level is positively correlated with the corresponding power of the suction component 20.

[0048] Specifically, the liquid level detector can be any existing or future developed liquid level detector that can detect a liquid level at a single point or multiple points. By way of example and not limitation, the liquid level detector can be a photoelectric liquid level sensor, an electrode-type liquid level sensor, a capacitive liquid level sensor, etc. Photoelectric liquid level sensors include integrated photoelectric liquid level sensors, separate photoelectric liquid level sensors, and multi-point photoelectric liquid level sensors.

[0049] The number of liquid level detectors may be one. In one embodiment, the number of liquid level detectors is one. The multiple target liquid level ranges include at least a first liquid level range and a second liquid level range. The liquid level detector is capable of detecting whether the liquid level in the solid-liquid separation chamber 11 has reached the target liquid level. In this article, reaching a certain position (such as a target liquid level) may include situations where it is equal to and higher than the position. When the liquid level in the solid-liquid separation chamber 11 reaches the target liquid level corresponding to the liquid level detector, the liquid level indicated by the liquid level information is in the second liquid level range. Otherwise, the liquid level indicated by the liquid level information is in the first liquid level range.

[0050] In a specific embodiment, the first liquid level range is [0, A], and the second liquid level range is [A, B]. Wherein, A represents the target liquid level corresponding to the liquid level detector, and B represents the highest liquid level of the solid-liquid separation chamber 11. Exemplarily, the liquid level detector can be an electrode type liquid level sensor, which may include an electrode group, and the electrode group includes two electrodes. The two electrodes are set at a certain height position of any liquid container (such as the solid-liquid separation chamber 11), and it is possible to detect whether the liquid in the liquid container reaches the height position where the electrodes are located. When the liquid does not reach the height position where the electrodes are located, the electrodes are exposed to the air, which is equivalent to the circuit not being turned on, the resistance of the electrode group is infinite, and the voltage across the electrode group is close to the power supply voltage. Conversely, when the liquid reaches the height position where the electrodes are located, it is equivalent to the liquid being a conductive medium, and the two electrodes can be connected. At this time, the voltage across the electrode group is different from the voltage when the liquid has not arrived. Therefore, the voltage across the electrode group can reflect whether there is liquid between the electrodes, that is, whether the liquid level in the liquid container has reached the target liquid level. It is understood that any multi-point liquid level detector or multiple single-point liquid level detectors can distinguish between two adjacent liquid level ranges within which the liquid level in the liquid container is located. The target liquid level corresponding to the liquid level detector is the upper limit of the first liquid level range and the lower limit of the second liquid level range of the two adjacent liquid level ranges. The upper limit of the first liquid level range is lower than the upper limit of the second liquid level range.

[0051] The number of liquid level detectors can also be set to multiple according to actual detection requirements. For example, when the liquid level range is three, the number of liquid level detectors can be two. When the liquid level range is five, the number of liquid level detectors can be four. When there are multiple liquid level detectors, the multiple liquid level detectors can be respectively set at different height positions in the solid-liquid separation chamber 11, so that the liquid level information detected by the multiple liquid level detectors can indicate the target liquid level range in which the current liquid level is located.

[0052] Multiple liquid level detectors can be separately arranged inside or outside the solid-liquid separation chamber 11, or embedded in the side wall of the solid-liquid separation chamber 11. For example, the multiple liquid level detectors are all separate photoelectric liquid level sensors, and each photoelectric liquid level sensor can be arranged on the side wall of the solid-liquid separation chamber 11 and corresponds to a target liquid level of the liquid. By way of example and not limitation, a prism can also be arranged at the position where the photoelectric liquid level sensor is arranged on the inner wall of the solid-liquid separation chamber 11. The photoelectric liquid level sensor can include a light-emitting diode and a photosensitive receiver. When the liquid level reaches the target liquid level, the liquid immerses the prism, and the light emitted by the light-emitting diode is refracted into the liquid, so that the photosensitive receiver cannot receive light or can only receive a small amount of light. If the liquid level does not reach the target liquid level and does not immerse the prism, the light emitted by the light-emitting diode can be directly reflected back to the photosensitive receiver by the prism. In this way, the liquid level in the solid-liquid separation chamber 11 can be detected.

[0053] The total liquid level range from the lowest liquid level to the highest liquid level in the solid-liquid separation chamber 11 can be divided into at least two liquid level ranges. Each liquid level range has a corresponding suction assembly 20 power. The suction assembly 20 powers corresponding to any two liquid level ranges can be the same or different. In one embodiment, different suction assembly 20 powers can be pre-set, and different suction assembly 20 powers correspond to different liquid level ranges. For example, at least two liquid level ranges can correspond one-to-one to at least two different suction assembly 20 powers.

[0054] In the above-mentioned embodiment where there are two liquid level ranges, the power of the suction assembly 20 can include a first power and a second power. The first power corresponds to the first liquid level range, and the second power corresponds to the second liquid level range. Assuming that the upper limit of the second liquid level range is higher than the upper limit of the first liquid level range, the second power can be greater than the first power. When the suction assembly 20 begins to operate, dirt begins to enter the solid-liquid separation chamber 11. At this time, the liquid level in the solid-liquid separation chamber 11 is within the first liquid level range, and the suction assembly 20 operates at the first power. As the dirt in the solid-liquid separation chamber 11 continues to increase until the liquid level in the solid-liquid separation chamber 11 is within the second liquid level range, the operating power of the suction assembly 20 is controlled to switch from the first power to the second power. In the above-mentioned embodiment where the first liquid level range is [0, A) and the second liquid level range is [A, B], if the liquid level indicated by the current liquid level information is less than A, the suction assembly 20 is controlled to operate at the first power. If the liquid level indicated by the current liquid level information is greater than or equal to A, the suction assembly 20 is controlled to operate at the second power. It is understood that if the liquid level in the solid-liquid separation chamber 11 is within the second liquid level range, it indicates that the sewage separation efficiency of the suction assembly 20 is low when operating at the first power, and the desired sewage separation efficiency cannot be achieved. Therefore, increasing the power of the suction assembly 20 from the first power to the second power can accelerate the speed at which sewage enters the sewage holding chamber 12, improve the sewage separation efficiency in the solid-liquid separation chamber 11, and prevent the sewage level in the solid-liquid separation chamber 11 from continuing to rise.

[0055] Exemplarily, the control method may further include: based on the liquid level indicated by the liquid level information, within a predetermined time after the power of the suction component 20 is switched from the first power to the second power, if the target liquid level range of the liquid level indicated by the liquid level information has not changed from the second liquid level range to the first liquid level range, then increasing the power of the suction component 20. The second power is greater than the first power, the second liquid level range is the liquid level range corresponding to the second power, and the first liquid level range is the liquid level range whose upper limit is lower than the upper limit of the second liquid level range. Optionally, increasing the power of the suction component 20 may include: switching the power of the suction component 20 from the second power to the third power, the third power is the power of the suction component 20 corresponding to the third liquid level range, and the third liquid level range is a liquid level range adjacent to the second liquid level range and whose upper limit is higher than the upper limit of the second liquid level range.

[0056] For example, after controlling the suction assembly 20 to operate at the second power, the liquid level changes in the solid-liquid separation chamber 11 can continue to be monitored. If the liquid level in the solid-liquid separation chamber 11 does not decrease, the power of the suction assembly 20 can be further increased. In one embodiment, the power of the suction assembly 20 also includes a third power, which is greater than the second power. After the suction assembly 20 operates at the second power, liquid level information detected by the liquid level detector continues to be obtained. If the liquid level indicated by the liquid level information remains within the second liquid level range after a predetermined time, the power of the suction assembly 20 can be controlled to increase from the second power to the third power. The predetermined time can be set to any suitable duration as needed. If the liquid level indicated by the liquid level information drops to the first liquid level range within the predetermined time, the power of the suction assembly 20 can be controlled to decrease from the second power to the first power, thereby reducing the operating energy consumption of the equipment. Alternatively, when the liquid level in the solid-liquid separation chamber 11 drops to the first liquid level range, the suction assembly 20 can be controlled to continue operating at the second power to ensure the wastewater separation efficiency of the cleaning equipment 100.

[0057] According to the above technical solution, by acquiring liquid level information in the solid-liquid separation chamber 11 and controlling the power of the suction assembly 20 based on this liquid level information, the power of the suction assembly 20 can be adjusted promptly when the liquid level in the solid-liquid separation chamber 11 changes. On the one hand, this ensures the efficient separation of wastewater in the solid-liquid separation chamber 11 and prevents wastewater accumulation. On the other hand, it also prevents the suction assembly 20 from operating at excessive power, which would cause energy loss.

[0058] According to some optional embodiments of the present application, the cleaning device 100 has multiple cleaning modes; the control method also includes: obtaining mode information of the cleaning device 100, the mode information is used to indicate the current cleaning mode of the cleaning device 100, and the current cleaning mode is one of the multiple cleaning modes; controlling the suction component 20 to operate according to the power of the suction component 20 corresponding to the current cleaning mode.

[0059] Optionally, multiple cleaning modes can correspond to different degrees of dirtiness in the area to be cleaned. In one embodiment, the cleaning modes include a strong cleaning mode and a normal cleaning mode. The strong cleaning mode corresponds to a situation where the area to be cleaned is more dirty. When the cleaning mode of the cleaning device 100 is the strong cleaning mode, the suction component 20 operates at a higher power, so that the dirt in the area to be cleaned can be quickly cleaned. The normal cleaning mode corresponds to a situation where the area to be cleaned is less dirty. The operating power of the suction component 20 corresponding to the normal cleaning mode is lower than the operating power of the suction component 20 corresponding to the strong cleaning mode. It will be understood that the current cleaning mode of the cleaning device 100 can be manually set by the user during use, or it can be automatically adjusted according to the detected dirtiness of the area to be cleaned. For example, when the cleaning mode of the cleaning device 100 is the normal cleaning mode, if it is detected that the area to be cleaned is more dirty, the cleaning mode of the cleaning device 100 can be controlled to automatically switch from the normal cleaning mode to the strong cleaning mode.

[0060] In one embodiment, the power of the suction assembly 20 corresponding to a plurality of cleaning modes can be preset respectively. The power of the suction assembly 20 corresponding to any two cleaning modes can be the same or different. For example, a plurality of cleaning modes can correspond one to one with a plurality of different powers of the suction assembly 20. In the embodiment in which the above-mentioned cleaning mode includes a strong cleaning mode and a normal cleaning mode, the power of the suction assembly 20 can include a fourth power and a fifth power. The fourth power corresponds to the normal cleaning mode, and the fifth power corresponds to the strong cleaning mode. The fifth power can be greater than the fourth power. After the cleaning device 100 is turned on, the mode information of the cleaning device 100 is obtained. If the current cleaning mode of the cleaning device 100 is the normal cleaning mode, the suction assembly 20 is controlled to operate at the fourth power. If the current cleaning mode of the cleaning device 100 is the strong cleaning mode, the suction assembly 20 is controlled to operate at the fifth power. In the embodiment in which the above-mentioned cleaning device 100 can automatically adjust the cleaning mode, when the cleaning mode of the cleaning device 100 changes, the suction assembly 20 can be controlled to operate according to the power of the suction assembly 20 corresponding to the changed cleaning mode. For example, when the cleaning mode of the cleaning device 100 is switched from the normal cleaning mode to the strong cleaning mode, the power of the suction component 20 is controlled to increase from the fourth power to the fifth power, so that the power of the suction component 20 can match the current cleaning mode of the cleaning device 100, thereby ensuring the sewage separation efficiency in the solid-liquid separation chamber 11.

[0061] In another embodiment, the power of the suction assembly 20 can be determined based on the liquid level in the solid-liquid separation chamber 11 and the current cleaning mode of the cleaning device 100. In the embodiment in which the power of the suction assembly 20 includes the fourth power and the fifth power, a liquid level detector can be provided in the solid-liquid separation chamber 11, and the liquid level range in this embodiment can include a first liquid level range and a second liquid level range. When the current cleaning mode of the cleaning device 100 is the normal cleaning mode, the suction assembly 20 can be controlled to operate at the fourth power, and the liquid level information detected by the liquid level detector can be obtained. When it is detected that the liquid level of the solid-liquid separation chamber 11 is in the second liquid level range, the power of the suction assembly 20 can be controlled to increase from the fourth power to the fifth power.

[0062] By adopting the above solution, the suction assembly 20 can be controlled to operate adaptively according to the power corresponding to the current cleaning mode, which can better prevent the problem of sewage entering the suction assembly 20 and causing the suction assembly 20 to fail. In addition, this adaptive working mode can effectively improve the user experience.

[0063] Specifically, the cleaning device 100 also includes a dirt detector, which is used to detect the dirt value of the area to be cleaned, and the dirt value represents the degree of dirtiness of the area to be cleaned; wherein, multiple cleaning modes correspond one-to-one to multiple degrees of dirtiness, and the degree of dirtiness is positively correlated with the power of the suction component 20 corresponding to the cleaning mode corresponding to the degree of dirtiness.

[0064] As described above, the various cleaning modes can correspond to different levels of dirtiness in the area to be cleaned. In some embodiments, the cleaning device 100 can adjust the current cleaning mode based on the dirtiness level of the area to be cleaned. For example, when the cleaning device 100 is in normal cleaning mode, if the dirtiness level detected by the dirtiness detector is high, the cleaning mode of the cleaning device 100 can be controlled to switch from normal cleaning mode to strong cleaning mode.

[0065] Further, in combination with Figures 1-3 and 5-6, the cleaning equipment 100 includes: a sewage suction pipe 30, which is connected to the solid-liquid separation chamber 11; the dirt detector is a colorimetric sensor, which is arranged in the sewage suction pipe 30, and the colorimetric sensor detects the colorimetric information of the sewage in the sewage suction pipe 30 through visible light; and / or the dirt detector is a turbidity sensor, which is arranged in the sewage suction pipe 30, and the turbidity sensor detects the turbidity of the sewage in the sewage suction pipe 30 based on the transmission principle; and / or the dirt detector includes an infrared transmitter and an infrared receiver, which are arranged in the sewage suction pipe 30, and the infrared receiver determines the degree of dirtiness by receiving the intensity of the infrared light emitted by the infrared transmitter and reflected, refracted and transmitted by the sewage.

[0066] The dirt detector can be any existing or future dirt detector. For example, the dirt detector can be a colorimetric sensor. Dirt on the clean surface (e.g., the floor) is guided along the suction pipe 30 into the solid-liquid separation chamber 11 under the negative pressure of the suction assembly 20. The colorimetric sensor is disposed on the suction pipe 30. The colorimetric sensor can detect the color of the wastewater in the suction channel 40 using visible light and determine the contamination of the wastewater based on the depth of its color.

[0067] Alternatively, the contamination detector can be a turbidity sensor. The turbidity sensor is disposed on the sewage suction pipe 30. During detection, the turbidity sensor can detect the turbidity of the sewage in the sewage suction pipe 30 based on the transmission principle. Specifically, when the detection light emitted by the turbidity sensor passes through a certain amount of sewage, the amount of detection light that penetrates depends on the amount of dirt in the sewage. When the amount of dirt increases, the amount of detection light that penetrates the sewage decreases accordingly. The turbidity sensor can calculate the contamination information of the sewage based on the amount of detection light that penetrates the sewage. Alternatively, the contamination detector can also include a turbidity sensor and a colorimetry sensor, and determine the contamination information of the sewage based on the measured turbidity and colorimetry.

[0068] In a specific embodiment, the contamination detector can be an infrared detection device installed on the sewage suction pipe 30. The infrared detection device includes an infrared transmitter and an infrared receiver. The infrared transmitter emits quantifiable infrared light, and the infrared receiver receives the infrared light. When the infrared light passes through the sewage in the suction channel 40, it undergoes physical phenomena such as reflection, refraction, and transmission, resulting in attenuation and obstruction of the infrared light along its path. The contamination value is ultimately determined based on the signal strength received by the infrared receiver.

[0069] The cleaning mode corresponds to the dirtiness level and the power of the suction assembly 20. Based on the dirtiness of the area being cleaned, the suction assembly 20 can operate at a power level that matches the dirtiness. The higher the dirtiness, the higher the power of the suction assembly 20, allowing for faster and more effective cleaning of the area.

[0070] According to the above technical solution, by matching the power of the suction component 20 with the degree of dirt, it can be ensured that the cleaning device 100 has good sewage separation efficiency when cleaning different degrees of dirt.

[0071] Specifically, there is one dirt detector; or there are multiple dirt detectors, and the average of the dirt values ​​measured by the multiple dirt detectors is the dirt value used to determine the degree of dirt. It is understood that the number of dirt detectors can be one or more. When multiple dirt detectors are used, the final dirt value can optionally be determined based on the average of the dirt values ​​measured by each dirt detector. This allows the dirt detector to obtain more accurate dirt value detection results, thereby ensuring that the cleaning device 100 is more accurately matched to different cleaning modes.

[0072] According to some optional embodiments of the present application, in combination with Figures 2 to 7, the cleaning device 100 also includes a suction channel 40, and the suction component 20 is connected to the dirty liquid holding chamber 12 through the suction channel 40 to suck the gas in the dirty liquid holding chamber 12 through the suction channel 40. A water detector is provided in the suction channel 40; the water detector is used to detect whether there is water in the suction channel 40; the control method also includes: obtaining water information detected by the water detector; when it is determined that there is water in the suction channel 40 based on the water information or when it is determined that the water volume in the suction channel 40 reaches a first target water volume based on the water information, controlling the suction channel 40 to close; and / or when it is determined that the water volume in the suction channel 40 reaches a second target water volume based on the water information, controlling the suction component 20 to close.

[0073] Specifically, the suction component 20 can suck the air in the sewage holding chamber 12 to form a negative pressure, so that the sewage in the solid-liquid separation chamber 11 can be sucked into the sewage holding chamber 12 under the action of the negative pressure, thereby achieving the effect of quickly and effectively separating the dirt pre-sucked into the solid-liquid separation chamber 11 into solid and liquid, making it difficult for the sewage in the solid-liquid separation chamber 11 to accumulate, and the sewage falling into the sewage holding chamber 12 can have a longer path to overcome the external force to do work along the suction channel 40 under the action of the negative pressure of the suction component 20 due to its own gravity, thereby avoiding the problem of sewage easily entering the suction component 20 and causing it to fail.

[0074] In one embodiment, a water presence detector is provided on the suction channel 40. The cleaning device 100 first obtains water presence information detected by the water presence detector. If the water presence information indicates that water is present in the suction channel 40, the suction assembly 20 is controlled to shut down. The water presence detector can be implemented using any existing or future developed liquid level detector that can perform single-point or multi-point liquid level detection. For example, the water presence detector itself can be a liquid level detector. By way of example and not limitation, the liquid level detector can be a photoelectric liquid level sensor, an electrode liquid level sensor, a capacitive liquid level sensor, etc.

[0075] The water presence detector can be located anywhere within the suction channel 40. For example, it can be located in the middle of the suction channel 40, at the suction inlet 41 of the suction channel 40, or at the suction outlet 42 of the suction channel 40. The suction inlet 41 represents the end of the suction channel 40 connected to the waste liquid holding chamber 12, and the suction outlet 42 represents the end of the suction channel 40 connected to the suction assembly 20. In one specific embodiment, the water presence detector is located at the suction inlet 41 of the suction channel 40. In this example, when wastewater enters the inlet of the suction channel 40, the water presence detector can promptly detect the ingress of water into the suction channel 40. It will be understood that when the suction assembly 20 is shut down, its power gradually decreases from the current power of the suction assembly 20 to zero. During this process, wastewater may still flow into the suction assembly 20 under the action of the suction assembly 20. Placing the wastewater detector at the suction inlet 41 of the suction channel 40 allows the suction assembly 20 to be shut down when wastewater enters the inlet of the suction channel 40. This can reduce the possibility of sewage continuing to enter the suction assembly 20 during the shutdown process of the suction assembly 20, preventing water from entering the suction assembly 20.

[0076] Multiple water presence detectors can be provided, and these detectors can be sequentially arranged along the axial direction of the suction channel 40. In one embodiment, when water presence information detected by any of the multiple water presence detectors indicates the presence of water in the suction channel 40, the suction assembly 20 can be controlled to shut down. Using multiple water presence detectors can avoid detection errors associated with a single water presence detector, further effectively preventing water from entering the suction assembly 20.

[0077] In another embodiment, if it is determined based on the water presence information that the amount of water in the suction channel 40 reaches a first target water volume, the suction assembly 20 is controlled to be closed. Optionally, the first target water volume can be set as needed. It is understandable that during the reciprocating push and pull of the cleaning device 100, the sewage in the sewage holding chamber 12 will be agitated. At this time, some sewage may splash into the suction channel 40. The amount of sewage entering the suction channel 40 may be small and insufficient to affect the suction assembly 20. The first target water volume can be the minimum water volume that is considered to be able to affect the normal operation of the suction assembly 20. Therefore, a first target water volume can be set, and when the water volume in the suction channel 40 reaches the first target water volume, the suction assembly 20 is controlled to be closed, otherwise the suction assembly 20 can be allowed to continue to operate. By setting this first target water volume, the closure of the suction assembly 20 can be controlled more accurately based on the impact of the sewage on the suction assembly 20, thereby reducing the execution of meaningless shutdown operations.

[0078] According to the above technical solution, by detecting whether there is water in the suction channel 40, when there is water in the suction channel 40 or when the amount of water in the suction channel 40 reaches the first target water amount, the suction component 20 is promptly controlled to close, which can effectively prevent water from entering the suction component 20 and is beneficial to extending the service life of the suction component 20.

[0079] Exemplarily, the control method may further include the following steps: obtaining water presence information detected by a water presence detector; and controlling the suction component 20 to close when determining that the water volume in the suction channel 40 reaches a second target water volume based on the water presence information.

[0080] The present embodiment is understood by referring to the above embodiment of controlling the suction assembly 20 to close when the water volume in the suction channel 40 reaches the first target water volume based on the water presence information, and is not described in detail here. The second target water volume can be the same as or different from the first target water volume.

[0081] Optionally, the inlet of the suction channel 40 is positioned at the upper portion of the sidewall of the waste liquid holding chamber 12. When the waste liquid holding chamber 12 is about to be filled or is already full, a large amount of waste water will also enter the suction channel 40. This amount of waste water is the second target water volume. In other words, when the water volume in the suction channel 40 reaches the second target water volume, it indicates that the waste liquid holding chamber 12 is about to be filled or is already full. Therefore, to ensure effective cleaning, the suction assembly 20 can be controlled to be closed, thereby ensuring effective waste water separation within the solid-liquid separation chamber 11.

[0082] According to the above technical solution, by detecting whether there is water in the suction channel 40, when the water level in the suction channel 40 reaches the second target water level, the suction component 20 is promptly controlled to be closed, which can effectively ensure the sewage separation effect.

[0083] Specifically, the water presence detector includes an electrode group, the electrode group includes two electrodes, and the water presence information is voltage information related to the voltage at both ends of the electrode group; the control method also includes: when the voltage value corresponding to the water presence information is greater than the first voltage threshold, determining that there is no water in the suction channel 40; when the voltage value corresponding to the water presence information is less than or equal to the first voltage threshold, determining that there is water in the suction channel 40.

[0084] The supply voltage of the electrode group is usually small. For example, in order to facilitate monitoring the change of the voltage across the electrode group,

[0085] After collecting the voltage value across the electrode assembly, the voltage value is amplified using an amplifier circuit, and the amplified voltage value is used as the voltage value corresponding to the water presence information. The amplification factor can be set as needed. For example, it can be 10 times, 15 times, 20 times, etc. In one embodiment, the first voltage threshold can be 4V. When the voltage value corresponding to the water presence information is greater than 4V, it is determined that there is no water in the suction channel 40. When the voltage value corresponding to the water presence information is less than or equal to 4V, it is determined that there is water in the suction channel 40. For example, when the voltage value corresponding to the water presence information is 3.5V, it is determined that there is water in the suction channel 40. Exemplarily, when the presence of water in the suction channel 40 is determined based on the voltage value corresponding to the water presence information, the suction assembly 20 can be controlled to shut down. Alternatively, the voltage value across the electrode assembly can be directly used as the voltage value corresponding to the water presence information. In one embodiment, the first voltage threshold can be 400mV. When the voltage value corresponding to the water presence information is greater than 400mV, it is determined that there is no water in the suction channel 40. When the voltage value corresponding to the water presence information is less than or equal to 400 mV, it is determined that water is present in the suction channel 40. In a specific embodiment, when the voltage value corresponding to the water presence information is less than 400 mV, it can be determined that the amount of water in the waste liquid holding chamber 12 is at least 1 / 2 of the capacity of the waste liquid holding chamber 12, that is, it is at least half full.

[0086] The above technical solution accurately determines the presence of water in the suction channel 40 by using voltage information related to the voltage across the electrode assembly. Based on the determination, the suction assembly 20 can be promptly shut down, thereby preventing failure of the suction assembly 20 due to water ingress.

[0087] Exemplarily, the control method further includes the following steps: when the voltage value corresponding to the presence or absence of water information is less than or equal to the first voltage threshold and greater than the second voltage threshold, determining that there is a small amount of water in the suction channel 40; when the voltage value corresponding to the presence or absence of water information is less than or equal to the second voltage threshold, determining that there is a large amount of water in the suction channel 40 and / or the sewage holding chamber 12 is full of sewage.

[0088] The first voltage threshold and the second voltage threshold can be set to any appropriate value as needed. In this article, when there is a large amount of water or a small amount of water in the suction channel 40, the voltage threshold detected by the water detector can be set according to actual needs. For example, the water level between the two electrodes being less than half of the maximum water level in the suction channel 40 can be regarded as a small amount of water in the suction channel 40. The water level between the two electrodes being greater than or equal to half of the maximum water level in the suction channel 40 can also be regarded as a large amount of water in the suction channel 40. Therefore, the voltage value detected when the water level between the two electrodes is equal to half of the maximum water level in the suction channel 40 can be selected as the second voltage threshold.

[0089] From the above description of the electrode type liquid level sensor, it can be understood that the electrode group is equivalent to a capacitor, and the two electrodes are equivalent to a capacitor.

[0090] The water and / or air between the electrodes is the medium of the capacitor. Due to the different dielectric constants of water and air, when the suction channel 40 changes from being dry to being filled with water, and when the water in the suction channel 40 gradually increases, the water level between the two electrodes rises and the medium changes. As the medium changes, the voltage across the electrode group will also change accordingly. The electrode group can form a loop with the voltage divider module. The higher the conductivity of the electrode group, the smaller the voltage across the electrode group. Therefore, the water level in the suction channel 40 can be determined based on the voltage across the electrode group. When the voltage across the electrode group is lower, it can be determined that there is more water in the suction channel 40.

[0091] In some embodiments, an exhaust port is provided at the upper portion of the sidewall of the waste liquid holding chamber 12, and the suction inlet 41 of the suction channel 40 can be connected to the exhaust port. In this case, when it is determined based on the water presence information that there is a large amount of water in the suction channel 40, it can be further determined that the waste liquid holding chamber 12 is full of waste water.

[0092] The second voltage threshold can represent the highest value of the voltage corresponding to the water presence information when there is a large amount of water in the suction channel 40. As described above, as the water level between the two electrodes rises, the voltage across the electrode group decreases. Therefore, the second voltage threshold is lower than the first voltage threshold. In one embodiment, the first voltage threshold is 400mV and the second voltage threshold is 200mV. When the voltage corresponding to the water presence information is greater than 400mV, it is determined that there is no water in the suction channel 40. When the voltage corresponding to the water presence information is less than or equal to 400mV and greater than 200mV, it is determined that there is a small amount of water in the suction channel 40. When the voltage corresponding to the water presence information is less than or equal to 200mV, it is determined that there is a large amount of water in the suction channel 40 and the waste liquid holding chamber 12 is full of waste water. For example, when the voltage corresponding to the water presence information is 150mV, it can be determined that there is a large amount of water in the suction channel 40 and the waste liquid holding chamber 12 is full of waste water. Since the detection values ​​of water detectors manufactured by different manufacturers and using different materials are different, the first voltage threshold and the second voltage threshold can be determined according to actual conditions.

[0093] In one embodiment, when it is determined that the dirty liquid receiving chamber 12 is full of dirty water, the cleaning device 100 may output a prompt message to remind the user to process the dirty water in the dirty liquid receiving chamber 12 .

[0094] In one or some embodiments, the cleaning device 100 may include an information output device. Exemplarily, the information output device may include one or more of a display device, a buzzer alarm, a speaker, a light-emitting device, a communication device, etc. The communication device may include any wired communication device and / or a wireless communication device. Exemplarily, the prompt information described herein may include one or more of audio information, text information, image information, video information, light information, etc. The display device is used to output one or more of text information, image information, and video information, and the buzzer alarm and the speaker are used to output audio information. The light-emitting device is used to output light information. The communication device is used to transmit any form of prompt information to any associated device. Associated devices may include but are not limited to personal computers, servers, mobile terminals (such as user's smart phones), etc. For example, the information output device may be a buzzer alarm that reminds the user that the sewage in the sewage holding chamber 12 is full of sewage by means of a buzzer alarm. For another example, the information output device may also be a display device that reminds the user that the sewage in the sewage holding chamber 12 is full of sewage by displaying characters such as "sewage is full". In one embodiment, a prompt can be provided in the form of graphics and text on the screen of a user terminal connected to the cleaning device 100, or a light prompt and / or voice prompt can be provided through an indicator light, a voice player, etc. on the cleaning device 100. For example, when it is determined that the waste liquid holding chamber 12 is full of waste water, a voice prompt "sewage is full" can be provided.

[0095] According to the above technical solution, the voltage value corresponding to the water presence information can be used to accurately determine the amount of water in the suction channel 40 and / or the condition of the waste liquid holding chamber 12. This result can serve as a basis for subsequent operations (such as outputting the above prompt information).

[0096] Furthermore, the water presence detector includes a light emitter and a light receiver; the control method includes: when the light signal value corresponding to the water presence information is greater than the first light signal threshold, determining that there is no water in the suction channel 40; when the light signal value corresponding to the water presence information is less than or equal to the first light signal threshold, determining that there is water in the suction channel 40.

[0097] For example, when the presence of water in the suction channel 40 is determined based on the optical signal value corresponding to the water presence information, the suction assembly 20 can be controlled to shut down. For example, when the optical signal value corresponding to the water presence information is greater than a first optical signal threshold, it is determined that there is no water in the suction channel 40. When the optical signal value corresponding to the water presence information is less than or equal to the first optical signal threshold, it is determined that there is water in the suction channel 40. In one specific embodiment, when the optical signal value corresponding to the water presence information is less than the first optical signal threshold, it can be determined that the amount of water in the waste liquid holding chamber 12 is at least 1 / 2 of its capacity, i.e., it is at least half full.

[0098] The above technical solution uses optical signal information to determine whether there is water in the suction channel 40, and the judgment result is accurate. Therefore, based on the judgment result, the suction component 20 can be controlled to be closed in time, thereby preventing the suction component 20 from failing due to water ingress.

[0099] In some embodiments, an exhaust port is provided at the upper portion of the sidewall of the waste liquid holding chamber 12, and the suction inlet 41 of the suction channel 40 can be connected to the exhaust port. In this case, when it is determined based on the water presence information that there is a large amount of water in the suction channel 40, it can be further determined that the waste liquid holding chamber 12 is full of waste water.

[0100] The cleaning device 100 and the control method described above can effectively improve the separation efficiency of sewage, thereby effectively preventing sewage from accumulating in the solid-liquid separation chamber 11 and further avoiding the problem of sewage being sucked into the suction component 20 and causing its failure.

[0101] Specifically, as shown in Figures 2 to 7 , the suction channel 40 has a suction inlet 41 and a suction outlet 42. The suction inlet 41 is in communication with the waste liquid holding chamber 12, and the suction outlet 42 is in communication with the suction assembly 20. A water detector is provided at at least one of the suction inlet 41, the suction outlet 42, and the middle portion of the suction channel 40. For example, the suction inlet 41 represents the end of the suction channel 40 connected to the waste liquid holding chamber 12, and the suction outlet 42 represents the end of the suction channel 40 connected to the suction assembly 20. In a specific embodiment, the water detector is provided at the suction inlet 41 of the suction channel 40. In this example, when sewage enters the entrance of the suction channel 40, the water detector can promptly detect the inflow of water into the suction channel 40.

[0102] Furthermore, a control valve for controlling the opening and closing of the suction channel 40 is provided in the suction channel 40. The closing of the suction channel 40 can be achieved by the control valve. When the water-free detection information is transmitted to the cleaning device 100, the control valve of the cleaning device 100 changes from an open state to a closed state.

[0103] The cleaning device 100 according to the second embodiment of the present application includes a sewage tank 10, a suction assembly 20 and a power supply unit (not shown). The sewage tank 10 has a solid-liquid separation chamber 11 and a sewage holding chamber 12. The solid-liquid separation chamber 11 and the sewage holding chamber 12 are connected. The suction assembly 20 is connected to the solid-liquid separation chamber 11 to provide power for dirt to enter the solid-liquid separation chamber 11. The suction assembly 20 is also connected to the sewage holding chamber 12 to provide power for sewage to enter the sewage holding chamber 12 from the solid-liquid separation chamber 11. The power supply unit supplies power to the device so that the suction assembly 20 can work. When the suction assembly 20 is started, the suction assembly 20 is controlled to drive the airflow to suck the sewage holding chamber 12 to drive the sewage in the solid-liquid separation chamber 11 into the sewage holding chamber 12. The power supply unit can be a rechargeable battery or a power adapter that is directly connected to a household socket to obtain AC power.

[0104] The cleaning device 100 may further include a controller, which is electrically connected to the suction component 20, and the controller is configured to: when the suction component 20 is started, control the suction component 20 to drive the airflow to suck the dirty liquid holding chamber 12 to drive the sewage in the solid-liquid separation chamber 11 to flow into the dirty liquid holding chamber 12. In other embodiments, the suction component 20 includes a controller, and the controller is configured to: when the suction component 20 is started, enable the suction component 20 to generate a driving airflow to suck the dirty liquid holding chamber 12 to drive the sewage in the solid-liquid separation chamber 11 to flow into the dirty liquid holding chamber 12. Specifically, when the suction component 20 is started, the controller controls the airflow at the air inlet end of the suction component 20 to suck the dirty liquid holding chamber 12 to drive the sewage in the solid-liquid separation chamber 11 to flow into the dirty liquid holding chamber 12. The controller may include any suitable processing device with data processing capabilities and / or instruction execution capabilities. For example, the controller can be implemented by a combination of one or more of a programmable logic controller (PLC), a digital signal processor (DSP), a field programmable gate array (FPGA), a programmable logic array (PLA), a central processing unit (CPU), an application specific integrated circuit (ASIC), a microcontroller unit (MCU) and other forms of processing units. For example, the controller can be the main control chip in the cleaning device 100, i.e., the main control MCU. All or part of the steps in the control method of the cleaning device 100 described above can be performed by the controller in the cleaning device 100.

[0105] According to the computer-readable storage medium of the third embodiment of the present application, a computer program / instruction is stored, and when the computer program / instruction is executed by the processor, the control method of the cleaning device 100 as described in the above embodiment is implemented. For example, the storage medium may include a read-only memory (ROM), an erasable programmable read-only memory (EPROM), a portable compact disk read-only memory (CD-ROM), a USB memory, or any combination of the above storage media. The computer-readable storage medium may be any combination of one or more computer-readable storage media.
