Description

Technical Field

[0001] The present application relates to the technical field of swimming pool cleaning, and in particular to a swimming pool cleaning device. Background Art

[0002] Pool cleaning is an important process to keep the pool water clean and safe. Regular pool cleaning not only ensures the water is clear and hygienic, but also prolongs the service life of the pool equipment. Usually, the cleaning of swimming pools mainly depends on manual cleaning or automatic cleaning equipment. Due to the low efficiency of manual cleaning, automatic cleaning equipment is becoming more and more popular.

[0003] The automatic cleaning device cleans the swimming pool by introducing water containing impurities from the water inlet into the machine for filtering. Usually, in a swimming pool, the dirt in different areas may be different, that is, the dirt may be concentrated in one or more areas. Therefore, the automatic cleaning device operating in the same way throughout the swimming pool may not be able to fully clean some areas, or may spend too much time and / or electricity on cleaning areas that are not too dirty, resulting in low cleaning efficiency. In order to solve the above technical problems, in the related art, a turbidity sensor is set in the water inlet of the automatic cleaning device or at a position close to the water inlet, and the turbidity in the swimming pool is detected by the turbidity sensor. Then, according to the turbidity of different areas of the swimming pool, a cleaning mode corresponding to the turbidity is performed.

[0004] However, when the cleaning equipment is cleaning the pool bottom, since the liquid in and near the water inlet contains more suspended particles and impurities, and the water flow velocity and turbulence are large, the liquid in and near the water inlet is gathered from all directions of the cleaning equipment and multiple positions. The impurity or suspended matter concentration in and near the water inlet is high, and it is impossible to feedback the dirtiness of the surface of the pool bottom. When the cleaning equipment is performing the pool wall cleaning operation, the dirt on the pool wall is affected by buoyancy and diffuses into the water faster, resulting in a decrease in the concentration of dirt impurities at the water inlet relative to the dirt on the pool wall. As a result, it is impossible to feedback the dirtiness of the cleaning area in real time when the cleaning equipment is in the cleaning operation state, affecting the accuracy of the measurement, thereby triggering unnecessary cleaning operations, resulting in increased power consumption of the equipment, a reduction in the effective cleaning area, low cleaning efficiency, and unreasonable cleaning strategies. Summary of the invention

[0005] The embodiment of the present application provides a swimming pool cleaning device, which is used to solve the problem that the turbidity sensor in the above-mentioned related art has low measurement accuracy, easily generates unnecessary cleaning operations, and leads to low cleaning efficiency.

[0006] In order to achieve the above objectives, the embodiments of the present application provide the following technical solutions:

[0007] A first aspect of an embodiment of the present application provides a swimming pool cleaning device, comprising:

[0008] A base body, comprising a bottom surface and a receiving cavity, wherein the bottom surface is provided with a liquid inlet connected to the receiving cavity;

[0009] A roller brush is rotatably connected to the base body, and the roller brush is spaced apart from the liquid inlet in the forward direction of the swimming pool cleaning device;

[0010] The filter assembly comprises a filter chamber, and when the substrate is in water, water containing impurities enters the filter chamber through the liquid inlet for filtration and then discharges the filtered water out of the substrate;

[0011] A turbidity detection device is arranged on the bottom surface of the substrate and is located between the liquid inlet and the roller brush. The turbidity detection device is used to detect the turbidity of the liquid; wherein,

[0012] In the forward direction of the swimming pool cleaning device, the distance from the turbidity detection device to the central axis of the liquid inlet is a first distance, the minimum distance from the turbidity detection device to the rotation central axis of the roller brush is a second distance, and the first distance is greater than the second distance.

[0013] The swimming pool cleaning device provided in the embodiment of the present application can be conveniently installed with mechanical and electronic components of the swimming pool cleaning device by setting a substrate and setting a receiving cavity on the substrate. The substrate can effectively protect the internal mechanical and electronic components from water, chemicals, impurities and physical damage, thereby extending the service life of the device. The substrate is generally relatively strong, and the strong substrate structure can improve the stability of the device and prevent it from overturning or being damaged when running in the swimming pool. By setting the substrate to include a bottom surface and setting a liquid inlet connected to the receiving cavity on the bottom surface, it can be ensured that the swimming pool cleaning device can directly inhale impurities and particles deposited on the bottom of the pool when it contacts the bottom of the pool, thereby improving the cleaning efficiency. By setting a roller brush, stubborn dirt, algae and sediment on the bottom and side walls of the swimming pool can be effectively scrubbed and removed, thereby improving the cleaning effect. The rotating motion of the roller brush can loosen and suspend particles deposited on the bottom of the pool, making them easier to be inhaled and filtered, thereby improving the overall cleaning efficiency.

[0014] By providing a filter assembly, the liquid entering the liquid inlet can be filtered, thereby achieving a cleaning effect.

[0015] By setting a turbidity detection device and setting the first distance to be greater than the second distance, that is, setting the turbidity detection device close to the roller brush and away from the liquid inlet, the change in water quality after the roller brush cleaning can be monitored in real time, which helps to evaluate the cleaning effect and adjust the cleaning strategy in time as needed to improve the cleaning efficiency. The turbidity detection device close to the roller brush can more accurately identify and locate the areas where pollutants are concentrated in the swimming pool, so that the swimming pool cleaning equipment can more effectively concentrate cleaning resources and improve cleaning efficiency. Near the roller brush, the disturbance of the water flow may be more obvious, and the detection device can directly sense these changes. Compared with setting the turbidity detection device in or near the liquid inlet, the sensitivity and accuracy of the detection can be improved.

[0016] By setting up a turbidity detection device, the water quality information in the swimming pool can be fed back in real time, so that the swimming pool cleaning equipment can dynamically adjust the cleaning force and speed of the roller brush according to the turbidity level of the liquid in the swimming pool to achieve more efficient cleaning. Since the turbidity detection device is directly located in the cleaning area, it can reduce false alarms caused by water flow fluctuations or changes in the position of the liquid inlet, provide more accurate water quality data, and improve the accuracy of detection, so that the swimming pool cleaning equipment can plan the cleaning path more intelligently, ensure that key areas are fully cleaned, reduce unnecessary repeated cleaning, and thus improve cleaning efficiency.

[0017] A second aspect of an embodiment of the present application provides a swimming pool cleaning device, comprising:

[0018] A base body, comprising a bottom surface and a receiving cavity, wherein the bottom surface is provided with a liquid inlet connected to the receiving cavity;

[0019] A roller brush is rotatably connected to the base body, and the roller brush is spaced apart from the liquid inlet in the forward direction of the swimming pool cleaning device;

[0020] The filter assembly comprises a filter chamber, and when the substrate is in water, water containing impurities enters the filter chamber through the liquid inlet for filtration and then discharges the filtered water out of the substrate;

[0021] A turbidity detection device is arranged on the bottom surface of the substrate and is located between the liquid inlet and the roller brush. The turbidity detection device is used to detect the turbidity of the liquid; wherein,

[0022] In the forward direction of the swimming pool cleaning device, the distance from the turbidity detection device to the central axis of the liquid inlet is a first distance, the minimum distance from the turbidity detection device to the rotational central axis of the roller brush is a second distance, and the first distance is greater than the second distance;

[0023] The swimming pool cleaning device includes a pool bottom cleaning state and / or a pool wall cleaning state. In the pool bottom cleaning state and / or the pool wall cleaning state, the roller brush rotates relative to the base to form a water flow. Driven by the roller brush, the water flow passes through the first distance to reach the turbidity detection device. After being detected by the turbidity detection device, the water flow passes through the second distance to reach the liquid inlet.

[0024] The swimming pool cleaning device provided in the embodiment of the present application can be conveniently installed with mechanical and electronic components of the swimming pool cleaning device by setting a substrate and setting a receiving cavity on the substrate. The substrate can effectively protect the internal mechanical and electronic components from water, chemicals, impurities and physical damage, thereby extending the service life of the device. The substrate is generally relatively strong, and the strong substrate structure can improve the stability of the device and prevent it from overturning or being damaged when running in the swimming pool. By setting the substrate to include a bottom surface and setting a liquid inlet connected to the receiving cavity on the bottom surface, it can be ensured that the swimming pool cleaning device can directly inhale impurities and particles deposited on the bottom of the pool when it contacts the bottom of the pool, thereby improving the cleaning efficiency. By setting a roller brush, stubborn dirt, algae and sediment on the bottom and side walls of the swimming pool can be effectively scrubbed and removed, thereby improving the cleaning effect. The rotating motion of the roller brush can loosen and suspend particles deposited on the bottom of the pool, making them easier to be inhaled and filtered, thereby improving the overall cleaning efficiency.

[0025] By providing a filter assembly, the liquid entering the liquid inlet can be filtered, thereby achieving a cleaning effect.

[0026] By setting up a turbidity detection device, the water quality information in the swimming pool can be fed back in real time, so that the swimming pool cleaning equipment can dynamically adjust the cleaning force and speed of the roller brush according to the turbidity level of the liquid in the swimming pool to achieve more efficient cleaning. Since the turbidity detection device is directly located in the cleaning area, it can reduce false alarms caused by water flow fluctuations or changes in the position of the liquid inlet, provide more accurate water quality data, and improve the accuracy of detection, so that the swimming pool cleaning equipment can plan the cleaning path more intelligently, ensure that key areas are fully cleaned, reduce unnecessary repeated cleaning, and thus improve cleaning efficiency.

[0027] By setting a turbidity detection device and setting the first distance greater than the second distance, that is, setting the turbidity detection device close to the roller brush and away from the liquid inlet, the changes in water quality after the roller brush cleaning can be monitored in real time, which helps to evaluate the cleaning effect and adjust the cleaning strategy in time as needed to improve the cleaning efficiency. The turbidity detection device close to the roller brush can more accurately identify and locate the areas where pollutants are concentrated in the swimming pool, so that the swimming pool cleaning equipment can more effectively concentrate cleaning resources and improve cleaning efficiency. Near the roller brush, the disturbance of the water flow may be more obvious, and the detection device can directly sense these changes, thereby improving the sensitivity and accuracy of the detection.

[0028] By setting the pool cleaning equipment to include the pool bottom cleaning state and / or the pool wall cleaning state, all-round cleaning of the pool can be achieved, thereby improving the applicability of the pool cleaning equipment. By directing the water flow to the turbidity detection device immediately after the roller brush stirs up the dirt, the turbidity of the water can be monitored in real time. This helps to evaluate the cleaning effect and adjust the cleaning strategy as needed.

[0029] In a possible implementation, the roller brush includes a front roller brush and a rear roller brush; wherein,

[0030] The direction from the rear roller brush to the front roller brush is the forward direction of the swimming pool cleaning device;

[0031] The turbidity detection device is arranged close to the front roller brush, and the distance from the turbidity detection device to the rotation center axis of the front roller brush is the second distance.

[0032] By setting the front roller brush and the rear roller brush, the combined use of the front roller brush and the rear roller brush allows the pool cleaning device to perform staged cleaning. The front roller brush can perform preliminary cleaning, while the rear roller brush can perform more detailed cleaning to ensure more thorough dirt removal. By setting the turbidity detection device close to the front roller brush, changes in water quality can be detected more quickly, so that responses and adjustments can be made more quickly, thereby improving cleaning efficiency. With the turbidity detection device close to the front roller brush, the pool cleaning device can plan cleaning paths and strategies more intelligently to ensure that key areas are fully cleaned and reduce unnecessary repeated cleaning. Compared with setting the turbidity detection device close to the liquid inlet, this can reduce false alarms caused by water flow fluctuations or changes in the position of the liquid inlet, and provide more accurate water quality data.

[0033] In a possible implementation, the roller brush includes a front roller brush and a rear roller brush; wherein,

[0034] The direction from the rear roller brush to the front roller brush is the forward direction of the swimming pool cleaning device;

[0035] The turbidity detection device is arranged close to the rear roller brush, and the distance from the turbidity detection device to the rotation center axis of the rear roller brush is the second distance.

[0036] By placing the turbidity detection device close to the rear roller brush, the turbidity after cleaning by the front roller brush can be detected, thereby monitoring changes in water quality in real time. This helps to comprehensively evaluate the effectiveness of the entire cleaning process and ensure that all dirt and impurities are effectively removed. By detecting the water quality after cleaning by the front roller brush, the equipment can more intelligently adjust the cleaning path and strategy to ensure that key areas are fully cleaned and reduce unnecessary repeated cleaning. Since the turbidity detection device is far away from the liquid inlet, it can reduce false alarms caused by water flow fluctuations or changes in the position of the liquid inlet, provide more accurate water quality data, and improve the accuracy of detection, so that the pool cleaning equipment can plan the cleaning path more intelligently, ensure that key areas are fully cleaned, reduce unnecessary repeated cleaning, and thus improve cleaning efficiency.

[0037] In a possible implementation manner, a ratio of the first distance to the second distance is greater than or equal to 1.5.

[0038] By setting the ratio of the first distance to the second distance to be greater than or equal to 1.5, the first distance can be made larger and the second distance smaller. A larger first distance means that the turbidity detection device can detect changes in the turbidity of the water before the liquid enters the substrate. This advance detection capability allows the swimming pool cleaning equipment to adjust operating parameters before the water flow enters the substrate, thereby improving cleaning efficiency. When the turbidity detection device is closer to the roller brush, the cleaning effect can be detected more quickly, reducing the interference of turbidity changes caused by the movement of the roller brush on the detection results, helping to improve the accuracy and reliability of the detection. By ensuring that the ratio of the first distance to the second distance is greater than or equal to 1.5, sufficient accommodation space can be provided for the mechanical and electronic components located in the substrate accommodation cavity, ensuring that the functions of all components are not interfered with while maintaining the compactness and aesthetics of the equipment.

[0039] In a possible implementation manner, a ratio of the first distance to the second distance is greater than or equal to 2.

[0040] By setting it this way, by ensuring that the ratio is greater than or equal to 2, the difference between the first distance and the second distance can be made larger, which is equivalent to the first distance being larger and the second distance being smaller. The smaller second distance enables the turbidity detection device to detect the turbidity change of the water earlier. This early detection capability allows the device to adjust the operating parameters and optimize the cleaning strategy before the water flows into the cleaning area. Since the turbidity detection device is closer to the roller brush (the second distance is smaller), the cleaning device can respond to turbidity changes more quickly. For example, when high turbidity is detected, the device can immediately increase the cleaning force or adjust the cleaning path to ensure better cleaning results. Through real-time monitoring and rapid response, the equipment can more effectively concentrate cleaning resources in the required areas, avoid unnecessary repeated cleaning, and improve overall cleaning efficiency. And it can provide more sufficient accommodation space for the mechanical and electronic components located in the base housing cavity to ensure that the functions of all components are not interfered with, so as to integrate more functions.

[0041] In a possible implementation manner, a ratio of the first distance to the second distance is between 2-3.

[0042] Such a setting can make the ratio between the first distance and the second distance within a reasonable range, ensure that the size of the pool cleaning device is not too large, ensure that the functions of all components are not disturbed, integrate more functions, and maintain the compactness and aesthetics of the device. By ensuring that the ratio of the first distance to the second distance is between 2 and 3, the pool cleaning device can better plan the cleaning path, ensure more effective cleaning in high turbidity areas, and avoid unnecessary repeated cleaning. A moderate distance ratio can enable the turbidity detection device to work in a relatively stable water flow, reducing the impact of water flow disturbance caused by the movement of the pool cleaning device or environmental changes on the detection accuracy.

[0043] In a possible implementation, the turbidity detection device includes a light emitting board, a light receiving board and a processing device; wherein,

[0044] The light emitting plate and the light receiving plate are arranged relatively spaced apart, a detection channel is formed between the light emitting plate and the light receiving plate, the opening of the detection channel faces the bottom surface, and the detection channel is used for liquid to pass through;

[0045] The light emitting plate is used to emit a first light beam to the light receiving plate, and the light receiving plate is used to receive a second light beam after passing through the liquid in the detection channel. The processing device is electrically connected to the light receiving plate, and the processing unit is used to obtain the turbidity of the liquid based on the second light beam.

[0046] Since the intensity change of the light beam can very sensitively reflect the concentration of suspended particles in the liquid, the turbidity detection device is set to obtain the turbidity of the liquid by optical measurement, which can improve the accuracy of turbidity measurement. Since the detection channel between the light emitting plate and the light receiving plate is open, the liquid does not need to directly contact the sensor when passing through, reducing the wear and contamination risk of the sensor. Optical detection can provide turbidity information in real time and quickly respond to changes in liquid turbidity, thereby better planning the cleaning path according to the turbidity of the liquid, ensuring more effective cleaning in high turbidity areas.

[0047] In a possible implementation manner, the first light beam emitted by the light emitting plate is infrared light or visible light.

[0048] By setting the first beam to infrared light, infrared light can provide stable measurement results due to its strong penetrating power and can penetrate thicker liquid layers or higher concentrations of suspended particles. Infrared light is less susceptible to interference from ambient light, especially in bright or changing lighting conditions, and can provide more reliable measurements. Infrared light scatters less in liquids, reducing measurement errors and improving detection accuracy.

[0049] By setting the first beam to visible light, costs can be reduced because visible light sources and detectors are generally more economical than infrared light systems. Visible light provides a variety of wavelength options, and the most suitable wavelength can be selected according to the specific application to optimize detection sensitivity and accuracy. Since visible light is more common in daily applications, related calibration and maintenance tools are more common, which is convenient for daily operation and maintenance.

[0050] In a possible implementation, the light receiving board includes a photosensor; wherein,

[0051] The photosensor is used to convert the received optical signal of the second light beam into an electrical signal;

[0052] The processing device is used to obtain the turbidity of the liquid according to the electrical signal.

[0053] By including a photosensor in the light receiving board, it is possible to accurately detect changes in light intensity and provide high-precision turbidity measurements. Photosensors generally have a fast response time and can detect changes in light signals in real time, thereby providing instant turbidity measurement results. Photosensors can detect tiny changes in light intensity and are suitable for detecting low turbidity liquids, ensuring the sensitivity and reliability of the measurement.

[0054] In a possible implementation, the photosensor includes a photodiode or a photomultiplier tube.

[0055] By setting the light receiving board as a photodiode or a photomultiplier tube, high-precision turbidity measurement can be achieved, the accuracy of the turbidity detection device can be improved, and the electrical signal can be quickly processed and analyzed, supporting real-time monitoring and feedback, which is suitable for applications that require instant response. According to the specific application requirements, a suitable light receiving device (photodiode or photomultiplier tube) can be selected to optimize performance and cost. Optoelectronic devices generally have high reliability and stability, and can provide consistent performance under various environmental conditions.

[0056] In a possible implementation, it also includes a water pump and a control device; wherein,

[0057] The water pump comprises an impeller and a driving motor, and the output end of the driving motor is drivingly connected to the impeller;

[0058] The control device is electrically connected to the drive motor, and is used to control the drive motor to rotate so as to drive the impeller to rotate. The rotating impeller applies suction to the liquid inlet, so that the liquid enters the filter cavity from the liquid inlet and is discharged out of the base through the impeller of the water pump.

[0059] The control device is electrically connected to the turbidity detection device, and is used to control the suction force of the water pump according to the turbidity of the liquid detected by the turbidity detection device.

[0060] With this arrangement, the water pump applies suction to the liquid inlet through the impeller, allowing the liquid to effectively enter the filter chamber. After being accelerated and pressurized by the impeller, the liquid can be discharged quickly, thereby improving the circulation speed and cleaning efficiency of the pool water. The control device is electrically connected to the drive motor and can automatically adjust the operating parameters of the water pump (such as speed and power) as needed, realizing an intelligent cleaning process and improving the convenience of equipment operation. Through the intelligent adjustment of the control device, the water pump can operate in different working modes to optimize energy consumption. For example, when the water quality is poor, the water pump can provide stronger cleaning ability, and when the water quality is good, the water pump can operate at a lower power to save energy.

[0061] In a possible implementation, the matrix further includes a filtration channel and a liquid outlet; wherein,

[0062] The filter channel is arranged between the liquid inlet and the liquid outlet, and the impeller of the water pump is located in the filter channel;

[0063] The filter assembly is located between the liquid inlet and the impeller. The liquid entering the filter cavity from the liquid inlet is filtered and then discharged from the base through the impeller of the water pump from the liquid outlet.

[0064] By setting a filter channel between the liquid inlet and the liquid outlet, the liquid flow path is optimized, ensuring that the liquid enters the impeller of the water pump directly for acceleration and discharge after filtration, thereby improving the overall water circulation efficiency. By setting the filter assembly between the liquid inlet and the impeller, the liquid can pass through the filter assembly before entering the impeller of the water pump, which ensures that most impurities and particles are removed before entering the water pump, protects the impeller of the water pump, reduces damage and wear to the impeller of the water pump, and extends the service life of the water pump. The filtered liquid is discharged through the impeller of the water pump at an accelerated speed, ensuring that the discharged water is cleaner, which helps to maintain the high standard of swimming pool water quality. Integrating the filter assembly and the water pump in a continuous channel simplifies the overall structure of the equipment and facilitates installation and maintenance.

[0065] In a possible implementation, a one-way valve is provided at the liquid inlet, and the one-way valve is used to control the liquid to enter from the liquid inlet and prevent the liquid or some impurities from flowing out from the liquid inlet.

[0066] This arrangement prevents liquid from flowing back into the pool or cleaning equipment when the pump stops or the pressure changes, keeping the system clean and efficient. By preventing liquid backflow, the check valve protects the pump and other components from unnecessary pressure fluctuations and liquid impact, reducing wear and potential damage, and extending the service life of the equipment. The check valve helps maintain stable pressure inside the filtration system and the pump, ensuring that the pump can quickly reach the required working state when starting, improving the response speed and efficiency of the equipment. Ensuring a one-way flow of liquid helps maintain a stable water flow and filtration effect, optimizes cleaning efficiency, and enables the equipment to remove impurities and particles more effectively. The check valve prevents air from entering the system when the pump stops, avoiding cavitation and reduced efficiency of the pump caused by air mixing. BRIEF DESCRIPTION OF THE DRAWINGS

[0088] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0089] In order to improve the adaptability of the swimming pool cleaning equipment so that the swimming pool cleaning equipment can adapt to swimming pools with different degrees of dirtiness in different areas, a turbidity sensor is usually installed in the water inlet of the swimming pool cleaning equipment or near the water inlet. The turbidity in the swimming pool is detected by the turbidity sensor, and then a cleaning mode corresponding to the turbidity is performed according to the turbidity in different areas of the swimming pool.

[0090] However, the water in and near the water inlet contains more suspended particles and impurities, resulting in a high initial turbidity reading, which may cause the pool cleaning equipment to over-clean, resulting in unnecessary energy consumption.

[0091] In addition, the water velocity and turbulence at the water inlet are usually large, which makes the turbidity detection device susceptible to water flow disturbances, affecting the accuracy of the measurement, and may cause over-cleaning or under-cleaning. Over-cleaning will lead to unnecessary energy consumption, while under-cleaning may lead to deterioration of water quality.

[0092] In addition, since impurities and dirt may accumulate in and at the water inlet, the turbidity detection device may require more frequent cleaning and maintenance, increasing maintenance costs and reducing user experience.

[0093] In order to solve the above technical problems, an embodiment of the present application provides a swimming pool cleaning device. By setting the turbidity detection device close to the roller brush and away from the liquid inlet, the detection accuracy of the turbidity detection device can be improved, so that the swimming pool cleaning device can plan the cleaning path more intelligently, ensure that key areas are fully cleaned, reduce unnecessary repeated cleaning, and thus improve cleaning efficiency.

[0094] The swimming pool cleaning device and the cleaning device provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0095] Figure 1 A schematic diagram of the structure of a swimming pool cleaning device provided in an embodiment of the present application. Figure 2 A schematic cross-sectional structure diagram of a swimming pool cleaning device provided in an embodiment of the present application.

[0096] It should be noted that, for the convenience of description, in the embodiment of the present application, the height direction of the swimming pool cleaning device is taken as the z direction, the axial direction of the roller brush is taken as the y direction, and the forward direction of the swimming pool cleaning device is taken as the x direction.

[0097] The present application embodiment provides a swimming pool cleaning device, such as Figure 1 As shown, the swimming pool cleaning device 100 may include a walking part 70, a base 10 and a roller brush 20. The walking part 70 is fixedly connected to the base 10 through a connecting piece, and the roller brush 20 is rotatably connected to the base 10. The walking part 70 drives the base 10 to move in the swimming pool while rotating the roller brush 20, so that dirt and other contaminants on the surface to be cleaned are stirred up, making it easier for the filter assembly 30 of the swimming pool cleaning device 100 to be sucked in and processed, thereby improving the overall cleaning efficiency.

[0098] Exemplarily, the walking part 70 may be connected to the base 10 via a connecting member, wherein the connecting member may be an axis, a bracket or other mechanical connecting member. In the embodiment of the present application, the specific structure of the connecting member is not further limited.

[0099] In addition, a driving device and a transmission device (such as a gear or a belt) for driving the walking part 70 may be disposed in the base 10 to drive the walking part 70 to drive the base 10 to move in the swimming pool.

[0100] like Figure 2 As shown, the base body 10 may include a bottom surface 11 and a receiving cavity 12 , and the bottom surface 11 is provided with a liquid inlet 15 communicating with the receiving cavity 12 .

[0101] It should be noted that the "surface to be cleaned" refers to the surface of the swimming pool that needs to be cleaned. When the bottom of the swimming pool needs to be cleaned, the surface to be cleaned refers to the bottom of the swimming pool. When the side wall of the swimming pool needs to be cleaned, the surface to be cleaned refers to the side wall of the swimming pool.

[0102] Exemplarily, the accommodating cavity 12 can be used to set mechanical and electronic components required for the swimming pool cleaning device 100, such as a circuit board, a battery, a water pump 40, a filter assembly 30, a driving device and a transmission device of the walking part 70, etc. In the embodiment of the present application, the type and quantity of the mechanical and electronic components set in the accommodating cavity 12 of the base 10 are not further limited.

[0103] The swimming pool cleaning device 100 provided in the embodiment of the present application can be conveniently installed with the mechanical and electronic components of the swimming pool cleaning device 100 by providing a substrate 10 and providing a receiving chamber 12 on the substrate 10. The substrate 10 can effectively protect the internal mechanical and electronic components from water, chemicals, impurities and physical damage, thereby extending the service life of the device. The substrate 10 is generally relatively strong, and the strong substrate 10 structure can improve the stability of the device and prevent it from overturning or being damaged when running in the swimming pool. By providing the substrate 10 with a bottom surface 11 and providing a liquid inlet 15 connected to the receiving chamber 12 on the bottom surface 11, it can be ensured that the swimming pool cleaning device 100 can directly inhale impurities and particles deposited on the bottom of the pool when contacting the bottom of the pool, thereby improving the cleaning efficiency. By providing a roller brush 20, stubborn dirt, algae and sediment on the bottom and side walls of the swimming pool can be effectively scrubbed and removed, thereby improving the cleaning effect. The rotational motion of the roller brush 20 can loosen and suspend particles deposited on the bottom of the pool, making them easier to be inhaled and filtered, thereby improving the overall cleaning efficiency.

[0104] Continue to see Figure 2 As shown, the swimming pool cleaning device 100 may also include a filter assembly 30 and a turbidity detection device 60. In the forward direction (x direction) of the swimming pool cleaning device 100, the roller brush 20 is spaced apart from the liquid inlet 15. The filter assembly 30 includes a filter chamber 31. When the base body 10 is in water, the water containing impurities enters the filter chamber 31 through the liquid inlet 15 for filtration and then is discharged out of the base body 10. The dotted line with an arrow in the figure represents the flow direction of the liquid filtration.

[0105] It should be noted that a filter element is provided in the filter chamber 31 of the filter assembly 30, which can remove fine particles and impurities in the water, such as sand, dust and tiny organic matter, so as to achieve the effect of cleaning the swimming pool and improve the water quality in the swimming pool. By providing the filter assembly 30, the liquid entering the liquid inlet 15 can be filtered, so as to achieve a cleaning effect.

[0106] The turbidity detection device 60 is disposed on the bottom surface 11 of the base 10 and is located between the liquid inlet 15 and the roller brush 20. The turbidity detection device 60 is used to detect the turbidity of the liquid. In the forward direction of the swimming pool cleaning device 100, the distance from the turbidity detection device 60 to the central axis of the liquid inlet 15 is a first distance L1, and the minimum distance from the turbidity detection device 60 to the rotational central axis of the roller brush 20 is a second distance L2. The first distance L1 is greater than the second distance L2.

[0107] It should be noted that, when the number of roller brushes 20 is greater than one, multiple roller brushes 20 can be arranged at intervals in the forward direction of the swimming pool cleaning device 100, and the “second distance L2” refers to the distance from the rotation center axis of the roller brush 20 farthest from the turbidity detection device 60 to the turbidity detection device 60.

[0108] “The first distance L1 is greater than the second distance L2 ” means that the turbidity detection device 60 is farther from the liquid inlet 15 , but closer to the roller brush 20 .

[0109] By setting the turbidity detection device 60 and setting the first distance L1 to be greater than the second distance L2, that is, setting the turbidity detection device 60 close to the roller brush 20 and away from the liquid inlet 15, the change in water quality after the roller brush 20 is cleaned can be monitored in real time, which helps to evaluate the cleaning effect and adjust the cleaning strategy in time as needed to improve the cleaning efficiency. The turbidity detection device 60 close to the roller brush 20 can more accurately identify and locate the area where pollutants are concentrated in the swimming pool, so that the swimming pool cleaning device 100 can more effectively concentrate cleaning resources and improve cleaning efficiency. Near the roller brush 20, the disturbance of the water flow may be more obvious, and the detection device can directly sense these changes, thereby improving the sensitivity and accuracy of the detection.

[0110] By providing the turbidity detection device 60, the water quality information in the swimming pool can be fed back in real time, so that the swimming pool cleaning device 100 can dynamically adjust the cleaning force and speed of the roller brush 20 according to the detected turbidity level of the liquid in the swimming pool, so as to achieve more efficient cleaning. Since the turbidity detection device 60 is directly located in the cleaning area, it can reduce false alarms caused by water flow fluctuations or changes in the position of the liquid inlet 15, provide more accurate water quality data, and improve the accuracy of detection, so that the swimming pool cleaning device 100 can plan the cleaning path more intelligently, ensure that key areas are fully cleaned, reduce unnecessary repeated cleaning, and thus improve cleaning efficiency.

[0111] In an embodiment of the present application, the swimming pool cleaning device includes a pool bottom cleaning state and / or a pool wall cleaning state. In the pool bottom cleaning state and / or the pool wall cleaning state, the roller brush rotates relative to the base to form a water flow. Driven by the roller brush, the water flow passes a first distance to reach the turbidity detection device. After being detected by the turbidity detection device, the water flow passes a second distance to reach the liquid inlet. Figure 3 The dashed lines with arrows in the figure represent the paths of water flow.

[0112] It should be noted that the pool bottom cleaning state refers to the state in which the roller brush cleans the pool bottom, and the surface to be cleaned is the pool bottom. The pool wall cleaning state refers to the state in which the roller brush cleans the pool wall, and the surface to be cleaned is the side wall of the swimming pool.

[0113] By setting the pool cleaning equipment to include the pool bottom cleaning state and / or the pool wall cleaning state, all-round cleaning of the pool can be achieved, thereby improving the applicability of the pool cleaning equipment. By directing the water flow to the turbidity detection device immediately after the roller brush stirs up the dirt, the turbidity of the water can be monitored in real time. This helps to evaluate the cleaning effect and adjust the cleaning strategy as needed.

[0114] Continue to see Figure 2 As shown, the number of the roller brushes 20 can be two, and the two roller brushes 20 are respectively located at the front end and the rear end of the base 10. For the convenience of description, the roller brush 20 located at the front end of the base 10 is referred to as the front roller brush 21, and the roller brush 20 located at the rear end of the base 10 is referred to as the rear roller brush 22. The direction from the rear end to the front end of the base 10 is the forward direction of the swimming pool cleaning device 100, that is, the x direction in the figure.

[0115] It should be noted that when the swimming pool cleaning device 100 is working, the front roller brush 21 is responsible for contacting the surface of the swimming pool for the first time, performing preliminary cleaning, and effectively loosening and removing dirt, algae and other sediments on the surface. Through the rotational motion, the front roller brush 21 stirs and suspends the dirt in the water, making it easier for it to be inhaled and processed by the filtering system of the device. The rear roller brush 22 is responsible for further cleaning to ensure that any dirt and impurities that the front roller brush 21 has not completely removed are completely removed. The rear roller brush 22 is generally designed to provide more detailed scrubbing to help polish the surface of the swimming pool and improve the surface finish and aesthetics. After the front roller brush 21 cleans, the rear roller brush 22 can handle any remaining dirt to ensure that the surface of the swimming pool is thoroughly clean. The action of the rear roller brush 22 further stirs the fine particles in the water, making them easier to be captured by the filtering system and optimizing the overall filtering effect.

[0116] The combined use of front and rear roller brushes enables more comprehensive and efficient cleaning in a single movement of the device, reducing the need for repeated cleaning. Through the synergistic effect of the front and rear roller brushes, the device can evenly clean the pool surface in different directions and angles to ensure no dead corners.

[0117] In a possible implementation, in the x direction, the turbidity detection device 60 is located between the liquid inlet 15 and the front roller brush 21, the turbidity detection device 60 is arranged close to the front roller brush 21, and the distance between the turbidity detection device 60 and the rotation center axis of the front roller brush 21 is the second distance L2. That is, the turbidity detection device 60 is arranged close to the front roller brush 21, and the liquid inlet 15 is located close to the rear roller brush 22.

[0118] By placing the turbidity detection device 60 near the front roller brush 21, water quality changes can be detected more quickly, so that responses and adjustments can be made more quickly, thereby improving cleaning efficiency. By placing the turbidity detection device 60 near the front roller brush 21, the swimming pool cleaning device 100 can more intelligently plan cleaning paths and strategies to ensure that key areas are fully cleaned and reduce unnecessary repeated cleaning. Compared with placing the turbidity detection device 60 near the liquid inlet 15, this can reduce false alarms caused by water flow fluctuations or changes in the position of the liquid inlet 15, and provide more accurate water quality data.

[0119] Continue to see Figure 2 As shown, the base 10 may further include a filtration channel 14 and a liquid outlet 16. Exemplarily, the liquid outlet 16 is located on the top surface 13 of the base 10. It is understood that the top surface 13 and the bottom surface 11 are separated from each other in the height direction of the swimming pool cleaning device 100.

[0120] In the embodiments of the present application, Figure 4 As shown, the swimming pool cleaning device 100 further includes a water pump 40 and a control device 50. The water pump 40 includes an impeller 42 and a drive motor 41, and the output end of the drive motor 41 is in transmission connection with the impeller 42. The filter channel 14 is arranged between the liquid inlet 15 and the liquid outlet 16, and the impeller 42 of the water pump 40 is located in the filter channel 14, and the filter assembly 30 is located between the liquid inlet 15 and the impeller 42.

[0121] The control device 50 is electrically connected to the drive motor 41. The control device 50 is used to control the rotation of the drive motor 41 to drive the impeller 42 to rotate. The rotating impeller 42 applies suction to the liquid inlet 15, so that the liquid enters the filter chamber 31 from the liquid inlet 15, is filtered, and then is discharged from the base 10 from the liquid outlet 16 through the action of the impeller 42 of the water pump 40.

[0122] In a possible implementation, the control device 50 may be electrically connected to the turbidity detection device 60 , and the control device 50 is further configured to control the suction force of the water pump 40 according to the turbidity of the liquid detected by the turbidity detection device 60 .

[0123] Exemplarily, the turbidity detection device 60 can send the detected turbidity information of the liquid to the control device 50, and the control device 50 controls the output power of the drive motor 41 according to the turbidity of the liquid, thereby adjusting the cleaning intensity. For example, when the water quality is poor, the control device 50 can control the drive motor 41 to operate at a larger output power, thereby increasing the suction force of the water pump 40, increasing the cleaning intensity, increasing the filtration speed, and thereby improving the cleaning ability. When the water quality is good, the control device 50 can control the drive motor 41 to operate at a smaller output power, thereby saving energy.

[0124] With such a configuration, the water pump 40 applies suction to the liquid inlet 15 through the impeller 42, so that the liquid effectively enters the filter chamber 31 of the filter channel 14. After the acceleration and pressurization of the impeller 42, the liquid can be discharged quickly, thereby improving the circulation speed and cleaning efficiency of the swimming pool water. The control device 50 is electrically connected to the drive motor 41, and can automatically adjust the operating parameters (such as speed and power) of the water pump 40 as needed, realizing an intelligent cleaning process and improving the convenience of operation of the equipment. Through the intelligent adjustment of the control device 50, the water pump 40 can operate in different working modes to optimize energy consumption.

[0125] It should be noted that in the embodiment of the present application, the specific structure of the water pump 40 is not further limited.

[0126] In a possible implementation, a one-way valve 17 is provided at the liquid inlet 15 , and the one-way valve 17 is used to control the liquid to enter from the liquid inlet 15 and prevent the liquid or some impurities from flowing out from the liquid inlet 15 .

[0127] Such a configuration can prevent liquid from flowing back into the swimming pool or cleaning equipment when the water pump 40 stops or the pressure changes, thereby maintaining the cleanliness and efficiency of the system. By preventing liquid from flowing back, the one-way valve 17 can protect the water pump 40 and other components from unnecessary pressure fluctuations and liquid impact, reduce wear and potential damage, and extend the service life of the equipment. The one-way valve 17 helps maintain the pressure stability inside the filtration system and the water pump 40, ensures that the water pump 40 can quickly reach the required working state when it starts, and improves the response speed and efficiency of the equipment. Ensuring the unidirectional flow of liquid helps maintain a stable water flow and filtering effect, optimizes the cleaning efficiency, and enables the equipment to more effectively remove impurities and particles. The one-way valve 17 can prevent air from entering the system when the water pump 40 stops, avoiding cavitation and reduced efficiency of the water pump 40 caused by air mixing.

[0128] It should be noted that the one-way valve 17 includes but is not limited to a check valve, a lift check valve, a butterfly check valve, a ball check valve, a diaphragm check valve or a spring check valve, etc. In the embodiment of the present application, the structure of the one-way valve 17 is not further limited.

[0129] In a possible implementation manner, a ratio of the first distance L1 to the second distance L2 is greater than or equal to 1.5.

[0130] By setting the ratio of the first distance L1 to the second distance L2 to be greater than or equal to 1.5, the first distance L1 can be made larger and the second distance L2 smaller. The larger first distance L1 means that the turbidity detection device 60 can detect the change in turbidity of the water before the liquid enters the substrate 10. This advance detection capability allows the swimming pool cleaning device 100 to adjust operating parameters before the water enters the substrate 10, thereby improving the cleaning efficiency. By ensuring that the ratio of the first distance L1 to the second distance L2 is greater than or equal to 1.5, sufficient accommodation space can be provided for the mechanical and electronic components located in the accommodation cavity 12 of the substrate 10, ensuring that the functions of all components are not interfered with while maintaining the compactness and aesthetics of the device.

[0131] Exemplarily, the ratio of the first distance L1 to the second distance L2 is greater than or equal to 2.

[0132] By setting it in this way, by ensuring that the ratio is greater than or equal to 2, the difference between the first distance L1 and the second distance L2 can be made larger, which is equivalent to the first distance L1 being larger and the second distance L2 being smaller. The smaller second distance L2 enables the turbidity detection device 60 to detect the turbidity change of the water earlier. This early detection capability allows the device to adjust the operating parameters and optimize the cleaning strategy before the water flow enters the cleaning area. Since the turbidity detection device 60 is closer to the roller brush 20 (the second distance L2 is smaller), the cleaning device can respond to turbidity changes more quickly. For example, when high turbidity is detected, the device can immediately increase the cleaning force or adjust the cleaning path to ensure a better cleaning effect. Through real-time monitoring and rapid response, the device can more effectively concentrate cleaning resources in the required areas, avoid unnecessary repeated cleaning, and improve the overall cleaning efficiency. And it can provide more sufficient accommodation space for the mechanical and electronic components located in the accommodating cavity 12 of the base 10 to ensure that the functions of all components are not interfered with, so as to integrate more functions.

[0133] In a possible implementation, the ratio of the first distance L1 to the second distance L2 is between 2-3.

[0134] Such a configuration can make the ratio between the first distance L1 and the second distance L2 within a reasonable range, ensure that the size of the pool cleaning device 100 is not too large, ensure that the functions of all components are not disturbed, integrate more functions, and maintain the compactness and aesthetics of the device. By ensuring that the ratio of the first distance L1 to the second distance L2 is between 2 and 3, the pool cleaning device 100 can better plan the cleaning path, ensure more effective cleaning in high turbidity areas, and avoid unnecessary repeated cleaning. A moderate distance ratio can enable the turbidity detection device 60 to work in a relatively stable water flow, reducing the impact of water flow disturbances caused by the movement of the pool cleaning device 100 or environmental changes on the detection accuracy.

[0135] Exemplarily, the ratio of the first distance L1 to the second distance L2 can be 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, etc., and can be set according to needs and the size of the swimming pool cleaning device 100. In the embodiment of the present application, the ratio of the first distance L1 to the second distance L2 is not further limited.

[0136] The structure of the turbidity detection device 60 will be described below with reference to the accompanying drawings.

[0137] Combination Figure 5 and Figure 6 As shown, the turbidity detection device 60 may include a light emitting plate 61, a light receiving plate 62 and a processing device 63. The light emitting plate 61 and the light receiving plate 62 are arranged relatively spaced apart, and a detection channel 69 is formed between the light emitting plate 61 and the light receiving plate 62. The opening of the detection channel 69 faces the bottom surface 11, and the detection channel 69 is used for liquid to pass through. The light emitting plate 61 is used to emit a first light beam to the light receiving plate 62, and the light receiving plate 62 is used to receive a second light beam after passing through the liquid in the detection channel 69. The processing device 63 is electrically connected to the light receiving plate 62, and the processing unit is used to obtain the turbidity of the liquid according to the second light beam.

[0138] In one possible implementation, Figure 6 As shown, the turbidity detection device 60 may include a shell 64, the shell 64 includes a first mounting cavity 65, a second mounting cavity 66 and a connecting portion 67, the first mounting cavity 65 and the second mounting cavity 66 are relatively spaced apart, the connecting portion 67 is located between the first mounting cavity 65 and the second mounting cavity 66, one end of the connecting portion 67 is connected to the outer wall of the first mounting cavity 65, and the other end is connected to the outer wall of the second mounting cavity 66.

[0139] In the height direction (z direction) of the swimming pool cleaning device 100, the connecting portion 67 is located between the two ends of the first installation cavity 65 and the second installation cavity 66, so that a detection channel 69 is formed between the outer wall of the portion of the first installation cavity 65 located on the side of the connecting portion 67 facing the bottom surface 11, the side of the connecting portion 67 facing the surface to be cleaned, and the outer wall of the portion of the second installation cavity 66 located on the side of the connecting portion 67 facing the bottom surface 11, and the opening of the detection channel 69 faces the bottom surface 11 (such as Figure 2 When the swimming pool cleaning device 100 is located in the swimming pool, the detection channel 69 is in direct contact with the liquid in the swimming pool.

[0140] Continue to see Figure 5 As shown, a first mounting portion 651 is provided in the first mounting cavity 65, and a second mounting portion 661 is provided in the second mounting cavity 66. The first mounting portion 651 and the second mounting portion 661 are arranged relatively spaced apart, and a connecting portion 67 is arranged between the first mounting portion 651 and the second mounting portion 661. A detection channel 69 is formed between the connecting portion 67 and a partial structure of the first mounting portion 651 close to the bottom surface 11 of the substrate 10 and a partial structure of the second mounting portion 661 close to the bottom surface 11 of the substrate 10.

[0141] The light emitting board 61 is mounted on a side of the first mounting portion 651 facing the first mounting cavity 65 , and the light receiving board 62 and the processing device 63 are both mounted on a side of the second mounting portion 661 facing the second mounting cavity 66 .

[0142] It should be noted that the accommodating cavity 12 of the base 10 may include a sealed cavity 121, wherein the circuit board, electronic components, batteries, etc. of the swimming pool cleaning device 100 are all arranged in the sealed cavity 121 to prevent the electronic components and batteries from being short-circuited when encountering liquid, thereby causing damage to the swimming pool cleaning device 100.

[0143] Exemplarily, the shell 64 of the turbidity detection device 60 is sealed and connected to the substrate 10. For example, a seal (e.g., a sealing ring) is provided between the shell 64 of the turbidity detection device 60 and the substrate 10, and the side of the shell 64 where the detection channel 69 is provided faces the surface to be cleaned, and the side of the shell 64 facing away from the detection channel 69 is located in the sealing cavity 121 to prevent liquid from entering the turbidity detection device 60 from the connection between the shell 64 and the substrate 10, thereby preventing damage to electronic components such as the light emitting plate 61, the light receiving plate 62 and the processing device 63.

[0144] In some embodiments, the material of the housing 64 may be a light-transmitting material, so as to ensure that the first light beam emitted by the light emitting board 61 can enter the detection channel 69 through the first mounting portion 651, and the second light beam after passing through the liquid in the detection channel 69 can enter the light receiving board 62 through the second mounting portion 661. Of course, in other embodiments, the housing 64 may also be made of other materials, and in the embodiment of the present application, the specific material of the housing 64 is not further limited.

[0145] Since the intensity change of the light beam can very sensitively reflect the concentration of suspended particles in the liquid, the turbidity detection device 60 is set to obtain the turbidity of the liquid by optical measurement, which can improve the accuracy of turbidity measurement. Since the detection channel 69 between the light emitting plate 61 and the light receiving plate 62 is open, the liquid does not need to directly contact the sensor when passing through, reducing the wear and contamination risk of the sensor. Optical detection can provide turbidity information in real time and quickly respond to changes in liquid turbidity, thereby better planning the cleaning path according to the turbidity of the liquid, ensuring more effective cleaning in high turbidity areas.

[0146] Of course, in other embodiments, the turbidity detection device 60 may also have other structures. In the embodiment of the present application, the structure of the turbidity detection device 60 is not further limited.

[0147] In a possible implementation, the first light beam emitted by the light emitting plate 61 is infrared light or visible light.

[0148] As an explanation, the spectral characteristics of water bodies are: water's absorption of visible light is mainly concentrated in the red and near-infrared regions. Pure water absorbs less blue light, so deep water looks blue. When there are other substances in the water, the reflectance spectrum curve will change. For example, when there is mud in the water, the reflectance of the visible light band will increase, and the peak will appear in the yellow-red region. When there is chlorophyll in the water, the near-infrared band will rise significantly. The reflectivity of the water body (except for the mirror reflection direction) is low in all bands, generally around 3%, which means that most of the incident light is absorbed or transmitted by the water body instead of reflected back. This low reflectivity makes water bodies generally look darker in natural environments, especially in remote sensing images. It is more prominent in the near-infrared part.

[0149] In the visible light band (about 0.4μm to 0.7μm), the reflectivity of clear water is about 4-5%. This means that water has a certain reflection of visible light, but it is still low. At 0.6μm (orange-red light), the reflectivity drops to 2-3%. This is because water absorbs red light more strongly and absorbs blue and green light less strongly, so water usually appears blue-green. After 0.75μm (near-infrared band), the reflectivity of water drops significantly, and water becomes almost a total absorber. This is because water molecules have strong absorption characteristics in the near-infrared band. When water becomes a total absorber in the near-infrared band, it does not reflect light, which makes the water body usually appear black or dark in near-infrared remote sensing images.

[0150] When a light beam passes through a water sample, the suspended particles in the water will cause the light to scatter. The intensity of the scattered light is related to the concentration of particles in the water: the more particles there are, the stronger the scattered light. The spectral curve of turbid water increases with the increase of the concentration of suspended sediment. Therefore, the turbidity of the water sample can be obtained through the spectral curve.

[0151] By setting the first beam to infrared light, infrared light can provide stable measurement results due to its strong penetrating power and can penetrate thicker liquid layers or higher concentrations of suspended particles. Infrared light is less susceptible to interference from ambient light, especially in bright or changing lighting conditions, and can provide more reliable measurements. Infrared light scatters less in liquids, reducing measurement errors and improving detection accuracy.

[0152] By setting the first beam to visible light, costs can be reduced because visible light sources and detectors are generally more economical than infrared light systems. Visible light provides a variety of wavelength options, and the most suitable wavelength can be selected according to the specific application to optimize detection sensitivity and accuracy. Since visible light is more common in daily applications, related calibration and maintenance tools are more common, which is convenient for daily operation and maintenance.

[0153] In a possible implementation, the light receiving plate 62 may include a photosensor 68. The photosensor 68 is used to convert the received optical signal of the second light beam into an electrical signal. The processing device 63 is used to obtain the turbidity of the liquid according to the electrical signal.

[0154] By configuring the light receiving plate 62 to include a photosensor 68, changes in light intensity can be accurately detected, providing high-precision turbidity measurement. The photosensor 68 generally has a fast response time and can detect changes in light signals in real time, thereby providing instant turbidity measurement results. The photosensor 68 can detect small changes in light intensity and is suitable for detecting low turbidity liquids, ensuring the sensitivity and reliability of the measurement.

[0155] Exemplarily, the light-sensitive sensor 68 may be a photodiode or a photomultiplier tube.

[0156] By setting the light receiving plate 62 as a photodiode or a photomultiplier tube, high-precision turbidity measurement can be achieved, the accuracy of the turbidity detection device 60 is improved, and the electrical signal can be quickly processed and analyzed, supporting real-time monitoring and feedback, which is suitable for applications that require immediate response. According to specific application requirements, a suitable light receiving device (photodiode or photomultiplier tube) can be selected to optimize performance and cost. Photoelectric devices generally have high reliability and stability and can provide consistent performance under various environmental conditions.

[0157] Of course, in other embodiments, the photosensor 68 may also be configured as other structures. In the embodiment of the present application, the specific type of the photosensor 68 is not further limited.

[0158] It should be noted that in the embodiments of the present application, "towards" refers to orientation in a broad sense, and is not limited to a frontal relative arrangement; and "deviating from" refers to deviation in a broad sense, and is not limited to a back-to-back parallel relative arrangement.

[0159] In the above embodiment, the turbidity detection device 60 is arranged close to the front roller brush 21 and away from the liquid inlet 15. Of course, in other embodiments, the turbidity detection device 60 can also be arranged close to the rear roller brush 22.

[0160] like Figure 7 As shown, in the x direction, the turbidity detection device 60 is located between the liquid inlet 15 and the rear roller brush 22, the turbidity detection device 60 is arranged close to the rear roller brush 22, and the distance between the turbidity detection device 60 and the rotation center axis of the rear roller brush 22 is the second distance L2. That is, the turbidity detection device 60 is arranged close to the rear roller brush 22, and the liquid inlet 15 is located close to the front roller brush 21.

[0161] By placing the turbidity detection device 60 close to the rear roller brush 22, the turbidity after the front roller brush 21 cleans and passes through the filter assembly 30 can be detected, thereby monitoring the change in water quality in real time. This helps to comprehensively evaluate the effect of the entire cleaning process and ensure that all dirt and impurities are effectively removed. By detecting the water quality after cleaning by the front roller brush 21, the swimming pool cleaning device 100 can more intelligently adjust the cleaning path and strategy to ensure that key areas are fully cleaned and reduce unnecessary repeated cleaning. Since the turbidity detection device 60 is far away from the liquid inlet 15, compared with placing the turbidity detection device 60 in or near the liquid inlet 15, it can reduce false alarms caused by water flow fluctuations or changes in the position of the liquid inlet 15, provide more accurate water quality data, and improve the accuracy of detection, so that the swimming pool cleaning device 100 can more intelligently plan the cleaning path, ensure that key areas are fully cleaned, reduce unnecessary repeated cleaning, and thus improve cleaning efficiency.

[0162] It should be noted that, in the embodiment of the present application, except for the different locations of the turbidity detection device 60 and the liquid inlet 15, the structures, principles and locations of other structures are the same as those of the embodiment of the present application. Figure 1-Figure 7 Therefore, the structure, principle and setting position of other structures in the embodiments of the present application can be referred to. Figure 1-Figure 7 The description in the embodiments shown in will not be repeated in the embodiments of the present application.

[0163] Of course, in other embodiments, the turbidity detection device 60 may also be disposed at other locations. In the embodiment of the present application, the location of the turbidity detection device 60 is not further limited.
