[0026] Figure 1A-1BThe schematic diagram shows the appearance of an automatic pool cleaning device 100 according to an embodiment of the present disclosure. The automatic pool cleaning device 100 can clean the bottom, pool wall, water and water surface of a pool (such as a swimming pool) as needed. Figure 1A The front side of the automatic pool cleaning device 100 is schematically shown. Figure 1B The rear side of the automatic pool cleaning device 100 is schematically shown. Figure 1A-1B As shown, the automatic pool cleaning device 100 may include structures / components such as a traveling mechanism 110, cleaning mechanisms 120 and 130; wherein the traveling mechanism 110 drives the automatic pool cleaning device 100 to travel; the first cleaning mechanism 120 and the second cleaning mechanism 130 are used, for example, to clean up garbage in the water, at the bottom of the water, and on the surface of the water, and to clean dirt on the bottom and wall of the pool. As an example, Figure 1A-1B The schematic diagram shows that the traveling mechanism 110 may include crawler-type traveling units on both sides of the lower part of the automatic pool cleaning device 100, so that the automatic pool cleaning device can travel on the bottom or wall of the pool to perform corresponding cleaning operations. However, the traveling unit is not limited to Figure 1A -1 B, but may include, for example, a wheeled traveling unit, which is not limited here.

[0027] It should be understood that Figure 1A-1B The automatic pool cleaning device 100 shown is only an example, and those skilled in the art may change one or more aspects thereof in terms of appearance, structure, layout, components, functions, etc. according to actual needs without departing from the principles of the present disclosure.

[0028] Figure 2 The figure schematically shows the internal structure of an automatic pool cleaning device 200 according to an embodiment of the present disclosure.

[0029] like Figure 2As shown, a water body cleaning chamber 230 may be provided inside the automatic pool cleaning device 200, and the water in the pool may enter the water body cleaning chamber via the water inlet 240 of the automatic pool cleaning device 200. The arrow in the figure schematically shows the general direction of the water flow. As an example, the water inlet may be provided at the bottom, side, front, and other positions of the housing of the automatic pool cleaning device 200. For example, the water inlet may be provided at the bottom of the housing of the automatic pool cleaning device 200, and the water in the pool may be sucked into the water inlet 240 through the suction action of the water pump 210 provided inside the automatic pool cleaning device 200, so as to enter the water body cleaning chamber of the automatic pool cleaning device, so as to filter the water in the pool. In addition, the water inlet may also be provided at the front of the automatic pool cleaning device 200, so that when the automatic pool cleaning device 200 travels in the water, the water in the direction of travel may be sucked into the water body cleaning chamber. In addition, a water surface water inlet may be provided on the side of the automatic pool cleaning device 200 along the waterline, so that when the automatic pool cleaning device 200 floats on the water surface, water may be sucked in through the water surface water inlet to clean the water surface.

[0030] As an example, a filtering unit, such as a filter basket, may be provided inside the water cleaning chamber of the automatic pool cleaning device 200. Optionally, the filter basket filters water sucked in through the water inlet 240 of the automatic pool cleaning device, traps dirt / garbage carried in the water in the filter basket, and discharges the filtered water through the drain outlet 250 of the automatic pool cleaning device.

[0031] As an example, the filter basket of the automatic pool cleaning device 200 may be configured to be detachably mounted inside the automatic pool cleaning device. As an example, an opening may be provided at the bottom of the filter basket to allow water sucked in through the water inlet of the automatic pool cleaning device to enter the interior of the filter basket. As another example, an opening may be provided on the side of the filter basket to allow water sucked in through the water surface water inlet of the automatic pool cleaning device to enter the interior of the filter basket. Optionally, a one-way valve (not shown) serving as a check valve may be provided at the opening through which water enters the filter basket to prevent dirt / garbage that enters the interior of the filter basket from flowing back into the pool. Figure 2 As shown, the filter basket can be set as a frame structure with mesh holes on at least one side, and a filter screen can be set at the position corresponding to the mesh hole. When water is discharged from the filter basket through the filter screen by the suction action of the water pump, the dirt and / or garbage carried in the water is intercepted by the filter screen inside the filter basket. As an example, at least one filter screen can be set on at least one wall of the filter basket.

[0032] As described above, the automatic pool cleaning device 200 can perform cleaning operations on the bottom, wall, water and water surface of a pool (e.g., a swimming pool) as needed, for example, to clean garbage in the water, on the bottom and on the water surface, and to clean dirt on the bottom and wall of the pool. As the cleaning operation of the automatic pool cleaning device proceeds, the intercepted dirt / garbage is likely to adhere to the filter screen of the filter basket. After the automatic pool cleaning device has been working for a period of time, the dirt / garbage attached to the filter screen of the filter basket will clog the filter screen, reducing the cleaning efficiency of the automatic pool cleaning device.

[0033] In addition, when the automatic pool cleaning device is propelled in water / on the water surface by water jetting, the water filtered by the filter basket can be sprayed out through the water jetting port of the automatic pool cleaning device to serve as the driving force for the automatic pool cleaning device to move. However, when the filter screen of the filter basket is clogged by dirt / garbage attached to the filter screen, the water flow is blocked when it is discharged through the filter screen of the filter basket, resulting in poor water inflow and drainage of the filter basket, thereby increasing propulsion power consumption and reducing driving efficiency.

[0034] To this end, it is necessary to promptly determine the blockage of the filter basket filter. If the filter is found to be clogged, it needs to be cleaned as soon as possible.

[0035] To this end, the present disclosure proposes a method for determining the clogging condition of the filter basket of an automatic pool cleaning device, which can accurately determine the clogging condition of the filter. When it is determined that the filter is clogged, an alarm signal can be automatically generated so that the filter can be cleaned in time.

[0036] Figure 3 The cross-sectional structure of the automatic pool cleaning device 300 according to the embodiment of the present disclosure is schematically shown. As an example, Figure 3 As shown, in the water inlet channel 310 of the automatic pool cleaning device, detection mechanisms 360 and 380 are provided. The water flow driving mechanism of the automatic pool cleaning device 300, such as a water pump, can drive water to flow through the water inlet channel 310 into the filter basket 320, and after being filtered by the filter screen of the filter basket 320, the filtered water is discharged from the automatic pool cleaning device.

[0037] As an example, the detection mechanism may include a signal transmitting end 360 and a signal receiving end 380, wherein the signal receiving end 380 may receive a signal transmitted from the signal transmitting end 360, thereby detecting the light transmittance state of the water flow in the water inlet channel, so as to determine the blockage condition of the filter based on the detection of the light transmittance state of the water flow.

[0038] Figure 4 FIG. 1 is a block diagram schematically showing a structure of an automatic pool cleaning device according to an embodiment of the present disclosure. Figure 4As shown, the automatic pool cleaning device 400 includes: a filter basket 410, which is detachably installed in the automatic pool cleaning device, wherein the filter basket includes a frame and a filter screen arranged on the frame; a water flow driving mechanism 420, which is configured to drive water to enter the filter basket 410 through an inlet channel to be filtered through the filter screen arranged on the filter basket; a detection mechanism 430, which is arranged in the inlet channel and is configured to detect the light transmittance state of the water flow; and a processing unit 440, which is configured to determine the blockage condition of the filter screen based on the detection condition of the light transmittance state of the water flow.

[0039] According to an embodiment of the present disclosure, the automatic pool cleaning device also includes a shell, and the filter basket is detachably installed in the shell of the automatic pool cleaning device; wherein a first water inlet is provided on the shell of the automatic pool cleaning device, and a second water inlet is provided on the frame of the filter basket, and the water inlet channel connects the first water inlet and the second water inlet.

[0040] As an example, the water flow driving mechanism of the automatic pool cleaning device, such as a water pump, under the control of the processing unit of the automatic pool cleaning device, draws the water in the pool into the filter basket through the first water inlet and the second water inlet, and discharges the water filtered by the filter net of the filter basket out of the automatic pool cleaning device through a drain port provided on the shell of the automatic pool cleaning device.

[0041] Figure 5 The cross-sectional structure of the automatic pool cleaning device 500 according to the embodiment of the present disclosure is schematically shown. Figure 5 As shown, a detection mechanism is provided in the water inlet channel of the automatic pool cleaning device. The water flow driving mechanism 260 of the automatic pool cleaning device 500, such as a water pump, can drive water to flow into the filter basket through the water inlet channel 310.

[0042] As an example, the detection mechanism may include a signal transmitting end 360 and a signal receiving end 380, wherein the signal receiving end 380 may receive a signal transmitted from the signal transmitting end 360, thereby detecting the light transmittance state of the water flow in the water inlet channel, so as to determine the blockage condition of the filter based on the detection of the light transmittance state of the water flow.

[0043] As an example, Figure 5It is further shown that in the above-mentioned automatic pool cleaning device, a movable baffle 390 is also included. As an example, the movable baffle 390 is disposed in the water inlet channel 310 of the automatic pool cleaning device 500, wherein the movable baffle can switch between a first state and a second state depending on the blockage condition of the filter screen of the filter basket. As an example, when the filter screen is blocked, the movable baffle 390 is in a first state to prevent the detection of the light transmission state of the water flow; and when the filter screen is not blocked, the movable baffle 390 is in a second state to allow the detection of the light transmission state of the water flow. For example, Figure 5 The schematic diagram shows the situation in which the movable baffle 390 is in the first state, that is, at least a part of the movable baffle 390 is located between the transmitting end and the receiving end of the detection mechanism, which prevents the detection mechanism from detecting the light transmittance state of the water flow in the water inlet channel.

[0044] As an example, in the above-mentioned automatic pool cleaning device, the detection mechanism includes a transmitting end and a receiving end, and when the movable baffle is in the first state, at least a portion of the movable baffle is located between the transmitting end and the receiving end of the detection mechanism.

[0045] As an example, in the above-mentioned automatic pool cleaning device, the water flow entering the filter basket through the water inlet channel can cause the movable baffle to switch between the first state and the second state. For example, when the filter screen of the filter basket is not blocked, the entire water flow channel from the water inlet on the housing of the automatic pool cleaning device to the drain on the housing of the automatic pool cleaning device is unobstructed, and when the water flow driving mechanism (for example, a water pump) of the automatic pool cleaning device draws water from the pool into the filter basket through the water inlet channel, the movable baffle is pushed open by the water flow, that is, the water body between the transmitting end and the receiving end of the detection mechanism can be transparent, and the receiving end can detect the signal, that is, the detection mechanism can detect the light-transmitting state of the water flow, indicating that the filter screen of the filter basket is not blocked.

[0046] On the contrary, after the automatic pool cleaning device has been performing cleaning operations for a certain period of time, a lot of garbage / dirt is trapped in the filter basket and the filter screen of the filter basket may be blocked. In this case, the water flow channel from the water inlet on the shell of the automatic pool cleaning device to the water outlet on the shell of the automatic pool cleaning device is blocked at the filter screen of the filter basket, resulting in poor water flow. When the water flow driving mechanism (for example, a water pump) of the automatic pool cleaning device draws water from the pool into the filter basket through the water inlet channel, the movable baffle cannot be pushed open by the water flow due to the poor water flow, thereby preventing the signal emitted by the transmitting end of the detection mechanism from passing through the water flow to the receiving end, that is, the receiving end cannot receive the signal emitted by the transmitting end, that is, the detection mechanism cannot detect the light transmittance state of the water flow. Therefore, it is possible to determine whether the filter screen of the filter basket is blocked based on the detection of the light transmittance state of the water flow by the detection mechanism.

[0047] According to an embodiment of the present disclosure, the degree of blockage of the filter screen of the filter basket can also be determined based on the degree of light transmittance of the water flow detected by the detection mechanism. For example, as the degree of blockage of the filter screen increases, the water flow driving mechanism (e.g., a water pump) of the automatic pool cleaning device reduces the smoothness of the water flow when using the same driving power, resulting in a decrease in the flow rate / water pressure of the water flow, which reduces the thrust of the water flow on the movable baffle, and increases the degree of obstruction of the movable baffle to the light transmittance of the water body between the signal transmitting end and the signal receiving end of the detection mechanism, thereby resulting in a decrease in the light transmittance of the water flow detected by the detection mechanism. Thus, the blockage of the filter screen of the filter basket can be determined based on the degree of light transmittance of the water flow detected by the detection mechanism.

[0048] According to an embodiment of the present disclosure, the detection mechanism may include a turbidity sensor, wherein the turbidity sensor can detect the light transmittance state of the water body at the water inlet flow channel.

[0049] Optionally, in the above-mentioned automatic pool cleaning device, the processing unit may be configured to determine the cleanliness of the water in the pool based on the light transmittance state of the detected water flow.

[0050] As an example, the processing unit may be a microprocessor, a microcontroller, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination of devices designed to perform the relevant processing functions.

[0051] For example, Figure 5 The detection mechanism shown may include a turbidity sensor, wherein the turbidity sensor may include a signal transmitting end and a signal receiving end, and according to the light transmittance state of the water body between the signal transmitting end and the signal receiving end, the turbidity sensor may generate a corresponding electrical signal to indicate the turbidity of the water body. As described above, since a movable baffle is provided between the signal receiving end and the signal transmitting end, the movable baffle may switch between a first state and a second state depending on the blockage of the filter screen of the filter basket. As an example, when the filter screen is blocked, the movable baffle is in a first state to prevent the turbidity sensor from detecting the light transmittance state of the water flow; and when the filter screen is not blocked, the movable baffle is in a second state to allow the turbidity sensor to detect the light transmittance state of the water flow. Specifically, when the filter screen of the filter basket is blocked, the water flow cannot be sucked into the filter basket, the water flow is not smooth, so that the water body between the signal transmitting end and the receiving end of the turbidity sensor is blocked and cannot transmit light. At this time, the turbidity sensor detects the maximum turbidity value and determines that the filter screen of the filter basket is blocked. When the filter screen of the filter basket is not blocked, the movable baffle is sucked up by the water flow and no longer blocks the light transmission of the water between the signal transmitting end and the receiving end of the turbidity sensor. The turbidity sensor can detect the turbidity of the water.

[0052] In addition, since the automatic pool cleaning device of the embodiment of the present invention can also use a turbidity sensor to detect water quality, for example, the turbidity of the water body, the power of the water flow driving mechanism (for example, a water pump) or the cleaning operation mode of the automatic pool cleaning device can be adjusted based on the detected water quality.

[0053] As an example, the detection sensor is not limited to a turbidity sensor, but may include other types of sensors capable of detecting the light transmittance state of a water body, such as an infrared sensor, a photoelectric sensor, which is not limited herein.

[0054] As an example, in the above-mentioned automatic pool cleaning device, the movable baffle is made of a flexible material. Since the movable baffle is flexible, it is sensitive to the flow rate of the water flow and can accurately reflect the blockage condition of the filter basket filter. Even if accidental external factors such as changes in the motion state or instantaneous changes in the rotation speed or rotation direction of the water pump cause sudden changes or errors in the detection data, these erroneous signals can be shielded by filtering so that corresponding processing can be performed based on the filtered signal, for example, generating an alarm signal for blockage of the filter basket filter, or adjusting the power of the water pump, changing the cleaning operation mode of the automatic pool cleaning device, etc.

[0055] Optionally, in the above-mentioned automatic pool cleaning device, the processing unit is further configured to generate an alarm signal when it is determined that the filter is clogged based on the detection of the light transmittance state of the water flow.

[0056] Figure 6 FIG. 1 is a flow chart schematically showing a method for an automatic pool cleaning device according to an embodiment of the present disclosure. Figure 6 As shown, the method may include: S610, driving water flow into the filter basket of the automatic pool cleaning device through the water inlet channel; S620, detecting the light transmittance state of the water flow at at least one position in the water inlet channel of the automatic pool cleaning device; and S630, determining whether the filter basket is blocked based on the detection of the light transmittance state of the water flow.

[0057] According to an embodiment of the present disclosure, a detection mechanism is provided in the water inlet channel of the automatic pool cleaning device; the state of the water flow in the water inlet channel can cause the movable baffle to switch between a first state and a second state; as an example, when the filter is blocked, the movable baffle is in the first state thereby preventing the detection of the light transmittance state of the water flow; and when the filter is not blocked, the movable baffle is in the second state thereby allowing the detection of the light transmittance state of the water flow.

[0058] As an example, when the water flow drive mechanism of the automatic pool cleaning device draws water from the pool, when the filter mesh of the filter basket of the automatic pool cleaning device is not blocked, the water flow in the water inlet channel is unobstructed and can push open the movable baffle, thereby allowing the detection mechanism to detect the light transmittance state of the water flow; on the contrary, when the filter mesh of the filter basket of the automatic pool cleaning device is blocked, the water flow in the water inlet channel is not smooth or even stagnant, and the movable baffle cannot be pushed open, so that the movable baffle hinders the detection mechanism from detecting the light transmittance state of the water flow; thereby, based on the detection mechanism's detection of the light transmittance state of the water flow, it can be determined whether the filter mesh of the filter basket is blocked.

[0059] As an example, in the above-mentioned automatic pool cleaning device, the detection mechanism includes a transmitting end and a receiving end; when the filter is blocked, the movable baffle is in a first state, and at least a portion of the movable baffle is located between the transmitting end and the receiving end of the detection mechanism, thereby preventing the detection mechanism from detecting the light transmittance state of the water flow.

[0060] Figure 7 FIG. 1 is a flow chart schematically showing a method for an automatic pool cleaning device according to an embodiment of the present disclosure. Figure 7 The above method may also include: S730, when it is determined that the filter screen of the filter basket is clogged based on the detection of the light transmittance state of the water flow, an alarm signal of filter basket clogging is generated to prompt the user to clean the filter screen of the filter basket of the automatic pool cleaning device, for example, an alarm message of filter basket clogging is displayed on the user's smart terminal such as a mobile phone, so that the user can start the filter screen cleaning operation mode of the automatic pool cleaning device through an application such as a smart terminal; or, after the alarm signal continues for a certain period of time, the filter screen cleaning operation mode of the automatic pool cleaning device is automatically started; and S740, in the filter screen cleaning operation mode of the automatic pool cleaning device, for example, garbage / dirt clogged on the filter screen is detached from the filter screen by vibrating the filter basket, thereby cleaning the filter screen.

[0061] As another example, after the filter mesh is clogged, the cleaning operation mode of the automatic pool cleaning device may be automatically paused, and the user may be prompted to manually clean the filter mesh of the filter basket.

[0062] like Figure 7 When it is determined that the filter screen of the filter basket is not blocked based on the detection of the light transmittance state of the water flow, the method may include: S750, normally detecting the turbidity of the water body through the turbidity sensor, and comparing the detected turbidity with a predetermined threshold; and S760, when the turbidity of the water body exceeds the predetermined threshold, adjusting the power of the water pump and / or changing the cleaning operation mode based on the detected turbidity of the water body to enhance the filtration of the water body and reduce the turbidity.

[0063] According to the above-mentioned embodiments of the present disclosure, whether the filter screen of the filter basket of the automatic pool cleaning device is blocked can be determined based on the detection of the light transmittance state of the water flow in the water inlet channel of the automatic pool cleaning device, and when it is determined that the filter screen is blocked, an alarm signal can be generated so that the filter screen can be automatically or manually cleaned in time.

[0064] In addition, based on the detection of the light transmittance of the water flow, the water quality of the water body can be determined so that in the cleaning operation mode of the automatic pool cleaning device, the power of the water pump can be adjusted to enhance the filtration of the water body and reduce turbidity.
