[0023] Furthermore, in the drawings, for clarity of illustration, dimensions may be exaggerated and not drawn to scale. Throughout the drawings, like reference numerals generally refer to like elements.

[0024] Figure 1 The schematic diagram shows the appearance of a pool cleaning device 100 according to an embodiment of the present disclosure. It can clean the bottom, wall, water and water surface of a pool (such as a swimming pool) as needed, for example, it can be used 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. Figure 1As shown, the pool cleaning device 100 may include structures / components such as a shell 110, a travel mechanism 120, and a cleaning mechanism 130. As an example, the pool cleaning device 100 may also include a buoyancy adjustment mechanism (not shown), so that the pool cleaning device can adjust its depth in the water as needed, for example, it can float on the water surface, dive into the water, or sink to the bottom of the water, so as to perform cleaning operations on the water surface, in the water, or at the bottom of the water. As an example, a control compartment, a power compartment, and a filter compartment (not shown) may be provided in the shell 100, wherein measurement and control circuits such as a control unit and an inertial measurement unit IMU may be installed in the control compartment, driving mechanisms such as a water pump and a drive motor may be provided in the power compartment, and a filtering mechanism may be provided in the filter compartment, so as to filter and purify the water entering the filter compartment through the water inlet, filter out the debris therein, and discharge the cleaned water out of the pool cleaning device through the water outlet. As an example, Figure 1 The traveling mechanism 120 may include crawler-type traveling mechanisms on both sides of the lower part of the pool cleaning device 100, so that the pool cleaning mechanism can travel in the water, on the bottom of the pool, or on the pool wall to perform corresponding cleaning operations. However, the traveling mechanism is not limited to Figure 1 The type shown in the figure may include, for example, a wheeled travel mechanism, which is not limited here. In addition, the travel mechanism may be coupled to a drive mechanism placed in a power bin inside the housing 110, thereby being driven by the drive mechanism. As an example, the travel mechanism may also include a water jet propulsion mechanism, so that the pool cleaning device 100 can travel by utilizing the reaction force generated by the jetted water flow. Optionally, the water jet propulsion mechanism may be arranged on both sides of the housing 100 of the pool cleaning device close to the waterline, so that when the pool cleaning device floats on the water surface, the water flow ejected by the water jet propulsion mechanism can travel in the horizontal direction, or it may be arranged at the top and / or bottom of the housing in the vertical direction of the housing 100, which is approximately the center position, so that the water flow ejected by the water jet propulsion mechanism can travel in the vertical direction. In addition, the direction of the water flow ejected by the water jet propulsion mechanism may also be set and controlled, so that the travel direction of the pool cleaning device is not limited to the horizontal and / or vertical direction, but may also be an inclined direction at a certain angle to the vertical direction. For those skilled in the art, the specific type, connection structure and working principle of the appropriate traveling mechanism can be selected according to the specific application occasion, size and other related factors of the pool cleaning device, but it is not limited thereto. As an example, the cleaning mechanism 130 may include a roller brush and other components located at the front side of the traveling mechanism along the traveling direction of the pool cleaning device. In addition, sensors such as ultrasonic sensors, infrared sensors, laser ranging sensors, etc. can also be set on the housing 110 to measure the positional relationship between the pool cleaning device and the surrounding environment.

[0025] According to an embodiment, the pool cleaning device 100 can be configured to drive the traveling mechanism 120 according to a specified mode under the control of the internal control unit to drive the pool cleaning device 100 to move along a specific track or in a specific direction on the bottom, wall, water, or surface of the pool; at the same time, the cleaning mechanism 130 can be activated to clean up garbage, debris, dirt, etc. on the bottom, wall, water, and / or surface of the pool, so that they are sucked into the filter bin of the pool cleaning device along with the water flow. Then, the garbage, debris, and dirt are filtered through the filter bin, and the garbage, debris, and dirt are trapped in the filter bin, and the cleaned water is discharged from the pool cleaning device, thereby cleaning the pool.

[0026] Figure 1 The 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.

[0027] Figure 2 is a schematic diagram of the internal structure of a pool cleaning device 200 according to another embodiment of the present disclosure.

[0028] like Figure 2 As shown, a water cleaning chamber 230 may be provided inside the pool cleaning device 200, and water in the pool may enter the water cleaning chamber via the water inlet 240 of the 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, or other positions of the housing of the pool cleaning device 200. For example, the water inlet may be provided at the bottom of the housing of the pool cleaning device 200, and the water in the pool may be sucked into the water inlet 240 and enter the water cleaning chamber of the pool cleaning device through the suction action of the water pump 210 provided inside the pool cleaning device 200, so as to filter the water in the pool. In addition, the water inlet may also be provided at the front of the pool cleaning device 200, so that when the pool cleaning device 200 moves in the water, water in the moving direction may be sucked into the water cleaning chamber. In addition, a surface water inlet may be provided on the side of the pool cleaning device 200 along the waterline so that when the pool cleaning device 200 floats on the water surface, the water surface may be cleaned by sucking water through the surface water inlet.

[0029] As an example, a filtering unit, such as a filter chamber, may be provided inside the water cleaning chamber of the pool cleaning device 200. Optionally, the filter chamber filters water sucked in through the water inlet 240 of the pool cleaning device, traps dirt / garbage carried in the water in the filter chamber, and discharges the filtered water through the drain port 250 of the pool cleaning device.

[0030] As an example, the filter compartment of the pool cleaning device 200 may be provided in the form of a filter basket 220 that is detachably mounted inside the pool cleaning device. As an example, the bottom of the filter basket may be provided with an opening for water drawn in through the water inlet of the 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 for water drawn in through the water surface inlet of the pool cleaning device to enter the interior of the filter basket. Optionally, a one-way valve (not shown) may be provided at the opening through which water enters the filter basket to serve as a check valve 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.

[0031] As described above, the 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 pool cleaning device performs the cleaning operation, the intercepted dirt / garbage is likely to adhere to the filter screen of the filter basket. After the 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 pool cleaning device.

[0032] In addition, when the pool cleaning device is propelled in water / on the water surface by water jet propulsion, the water filtered by the filter basket can be sprayed out through the water spray port of the pool cleaning device to serve as the power for the 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.

[0033] For this reason, it is necessary to clean the filter screen of the filter basket in time.

[0034] Usually, manual cleaning can be adopted. For example, during the period when the pool cleaning device stops working, the filter basket can be taken out from the pool cleaning device to clean the filter screen of the filter basket or replace the filter basket / filter screen.

[0035] However, the manual cleaning method is not only troublesome, but also requires frequent cleaning of the filter basket, which affects the normal cleaning operation time of the pool cleaning device and reduces the cleaning operation efficiency of the pool cleaning device.

[0036] To this end, the present disclosure proposes a method for automatically cleaning the filter screen of the filter unit of the pool cleaning device in real time, thereby eliminating the defects of the above-mentioned manual cleaning method to clean the filter screen of the filter unit.

[0037] According to one aspect of the present disclosure, a pool cleaning device is provided, which can operate in a first operating mode and / or a second operating mode. Figure 3A As shown, the pool cleaning device 300 includes: a water cleaning chamber 310; a filter unit 320, which is arranged inside the water cleaning chamber, and the filter unit is provided with a filter screen, and the water flow flowing into / out of the water cleaning chamber is filtered through the filter screen to separate the debris therein; at least one first driving component 330, which drives the water flow to flow into / out of the water cleaning chamber 310 in the first working mode of the pool cleaning device 300; and at least one second driving component 340, which drives the filter unit to vibrate in the second working mode of the pool cleaning device to separate the debris from the filter screen.

[0038] As an example, the first driving component 330 may include a water pump of a pool cleaning device, such as Figure 2 The water pump 210 in the pool. Optionally, the pool cleaning device 300 draws / absorbs water from the pool by means of the water pump in the first working mode, that is, drives the water flow through the water inlet of the pool cleaning device into the filter unit provided in the water cleaning chamber, and is discharged from the filter unit through the filter screen of the filter unit, and finally discharged into the pool through the drain port of the pool cleaning device. As an example, the drain port may include a water jet and / or nozzle used as a water jet propulsion for the pool cleaning device. Optionally, the drain port may be provided at at least one of the two sides of the fuselage, the rear end of the fuselage, the top of the fuselage, the bottom of the fuselage, etc. of the pool cleaning device as needed, and is not limited here. For example, as Figure 2 As shown, the drain outlet can be set on the top of the fuselage, so that when the pool cleaning device is cleaning the pool wall, the reaction force generated by the water discharge from the drain outlet can apply pressure to the pool cleaning device toward the pool wall, so that the travel mechanism of the pool cleaning device (for example, tracks or wheels) can fit the pool wall, thereby facilitating the pool cleaning device to travel on the pool wall and / or perform cleaning operations on the pool wall.

[0039] As an example, the second driving component 340 may include a vibration element, such as a vibration motor. Optionally, in the second working mode of the pool cleaning device 300, the vibration of the vibration motor drives the filter unit 320 to vibrate so that the dirt / garbage collected / intercepted on the filter screen of the filter unit 320 is separated from the filter screen by vibration. As an example, the vibration motor can be set at the bottom of the filter unit, that is, in the gap between the bottom of the filter unit and the bottom plate of the water cleaning chamber.

[0040] Figure 4 is a partial schematic diagram of a filter unit according to an embodiment of the present disclosure. Figure 4 As shown, the filter unit 320 is in the form of a filter basket, and water flows into the filter basket through the water inlet 440. The second drive component 340 can be set at the position of the basket ring at the bottom of the filter basket; or it can be set at the center of the bottom of the filter basket. Of course, according to actual needs, the second drive component can also be set at other positions of the filter unit, for example, at the gap between the side wall of the filter unit and the side wall of the water cleaning chamber, and its specific installation position is not limited here.

[0041] In addition, the number of second driving components may be more than one. For example, multiple second driving components may be symmetrically arranged at the bottom of the filter unit, or multiple second driving components may be symmetrically arranged on the side wall of the filter unit, which is not limited here.

[0042] As an example, the second driving component drives the filter unit so that the filter unit vibrates in a direction perpendicular to its bottom and / or in a direction parallel to its bottom. In other words, the direction in which the filter unit vibrates is not limited as long as the purpose of separating the dirt / garbage intercepted / collected on the filter screen of the filter unit from the filter screen can be achieved.

[0043] Optionally, the first working mode is a normal cleaning operation mode of the pool cleaning device, and the second working mode is a filter cleaning mode of the pool cleaning device.

[0044] As an example, in the second working mode of the pool cleaning device, the at least one first driving component stops driving water flow into / out of the water cleaning chamber. That is, in the filter cleaning mode of the pool cleaning device, the first driving component stops driving water flow into / out of the filter unit, and the filter unit vibrates under the vibration of the second driving unit, so that the dirt / garbage intercepted / accumulated by the filter is separated from the filter.

[0045] Optionally, the operating time and / or frequency of the second drive unit in the second operating mode can be set, that is, the duration of continuous vibration of the second drive unit, for example, several seconds to several minutes; or the number of times and the corresponding duration of intermittent vibration of the second drive unit in the second operating mode can be set.

[0046] As an example, when the pool cleaning device operates in the second operating mode for a time threshold, the at least one second driving component stops driving the filter unit to vibrate, and the pool cleaning device exits the second operating mode.

[0047] For example, the time threshold may be set to range from a few seconds, tens of seconds to a few minutes.

[0048] As an example, the horizontal and / or vertical offset of the filter unit caused by the vibration of the filter unit driven by the second driving component is less than or equal to the first threshold. Optionally, the first threshold can be set to 1 cm. Setting the first threshold to be relatively small can save space for installing the filter unit on the one hand, and prevent the filter unit from vibrating and causing the offset to be too large, causing the water inlet corresponding to the filter unit to deviate.

[0049] As an example, Figure 3B As shown, the pool cleaning device may further include at least one detection unit 350 for determining the blockage of the filter unit. Specifically, the detection unit may be used to determine the blockage degree of the filter screen of the filter unit so as to determine whether to start the second working mode of the pool cleaning device; the pool cleaning device determines whether to exit the first working mode and enter the second working mode based on the detection result of the detection unit.

[0050] Optionally, the at least one detection unit comprises at least one of a power detection component of the first driving component or a water flow state detection component, so as to determine the degree of clogging of the filter screen of the filter unit.

[0051] As an example, the detection unit can be used as a power detection component to detect the operating power of the first driving component. For example, the operating current and / or voltage of the pump motor of the water pump serving as the first driving component can be detected to determine the operating power of the water pump, and then determine the degree of blockage of the filter; or the RPM (revolutions per minute) of the impeller of the water pump serving as the first driving component can be detected to determine the degree of blockage of the filter.

[0052] Generally, as the filter screen of the filter unit becomes more clogged, the operating power of the pump motor will change and / or the RPM of the impeller of the water pump will tend to decrease. Therefore, the clogging degree of the filter screen of the filter unit can be determined by monitoring the operating power of the pump motor and / or the RPM of the impeller of the water pump.

[0053] In addition, the degree of clogging of the filter screen of the filter unit will also affect the parameters such as the pressure and speed of the water flow. Therefore, the degree of clogging of the filter screen of the filter unit can be determined by detecting the state of the water flow entering / exiting the filter unit and / or entering / exiting the pool cleaning device. For example, the state of the water flow entering / exiting the pool cleaning device in the first working mode can be detected by a water pressure detection sensor and / or a water flow rate sensor near the water inlet / outlet of the pool cleaning device, and the degree of clogging of the filter screen of the filter unit can be determined accordingly. Generally, as the degree of clogging of the filter screen of the filter unit increases, the water pressure difference between the water inlet / outlet will become smaller and / or the water flow rate will become slower. Therefore, the degree of clogging of the filter screen of the filter unit can be determined by detecting the state of the water flow entering / exiting the pool cleaning device.

[0054] As an example, the number of detection units may be more than one, and the specific installation position of the detection unit may be set according to actual needs; for example, the detection unit may be set near the water inlet and / or outlet of the pool cleaning device, or near the first driving component of the pool cleaning device. The installation position and / or number of the detection unit may be set by those skilled in the art according to actual needs and are not limited here.

[0055] As an example, Figure 3C As shown, the above-mentioned pool cleaning device may further include at least one locking component 360. Optionally, the locking component is disposed between the water cleaning chamber and the filter unit. In the first working mode of the pool cleaning device, the locking component locks the filter unit with the water cleaning chamber, so that the filter unit can be firmly fixed to the inner wall of the water cleaning chamber; and in the second working mode of the pool cleaning device, the locking component unlocks the filter unit from the water cleaning chamber, that is, the filter unit has the ability to move in a small range and can vibrate under the drive of the second driving component.

[0056] Optionally, the at least one locking component automatically locks the filter unit and the water cleaning chamber when the filter unit stops vibrating.

[0057] As an example, the locking member may be disposed between the bottom of the filter unit and the bottom plate of the water cleaning chamber, or the locking member may be disposed between the side wall of the filter unit and the side wall of the water cleaning chamber.

[0058] In addition, the number of locking components may be more than one, for example, multiple locking components may be symmetrically arranged at the bottom of the filter unit, or multiple locking components may be symmetrically arranged on the sidewall of the filter unit. According to the embodiments of the present disclosure, the installation position and / or number of the locking components may be set by those skilled in the art according to actual needs and are not limited here.

[0059] As an example, the at least one locking component may include a magnetic element, a solenoid valve, a pneumatically driven locking element, a hydraulically driven locking element, etc., and the specific type and structure are not limited herein.

[0060] Optionally, the filter unit is a filter basket, the filter screen is arranged on at least one wall of the filter basket; and the at least one second driving component is arranged at the bottom of the filter basket.

[0061] As an example, Figure 3D As shown, the pool cleaning device may also include a debris collection unit 370, which may be used to collect dirt / garbage detached from the filter screen of the filter unit. Optionally, the debris collection unit may be disposed at the bottom of the filter unit, for example, it may be configured to be detachably mounted at the bottom of the filter unit, so that when the filter unit is cleaned, the debris collection unit may be removed, the dirt / garbage collected / deposited therein may be removed, and the debris collection unit may be reinstalled to the filter unit. Alternatively, the debris collection unit may be configured to be disposable, and a new debris collection unit may be replaced when the collected / deposited dirt / garbage reaches a certain amount, or when the pool cleaning device is used for a certain period of time.

[0062] Figure 5 FIG. 1 is a partial schematic diagram of a filter unit according to another embodiment of the present disclosure. Figure 5 As shown, the bottom of the filter basket as the filter unit can be designed as a frame structure with openings. Optionally, the debris collection unit can be installed on the inner side or outer side of the bottom frame of the filter basket (not shown).

[0063] Figure 6 A flow chart of a method for a pool cleaning device according to an embodiment of the present disclosure is shown. Figure 6 As shown, the method may include: S610, detecting the state of water flow; S620, based on the detected state of water flow, stopping at least one first driving component of the pool cleaning device to drive water flow into / out of the water cleaning chamber of the pool cleaning device; and starting at least one second driving component of the pool cleaning device to drive the filter unit of the pool cleaning device to vibrate in at least one direction.

[0064] As an example, Figure 7 As shown, the above method may also include: S710, in a first working mode, driving water to flow into / out of a water cleaning chamber by at least one first driving component of the pool cleaning device, and filtering the water entering the water cleaning chamber by a filter screen of a filter unit of the pool cleaning device to separate debris therein; S720, in a second working mode, driving the filter unit to vibrate by at least one second driving component of the pool cleaning device to separate the debris from the filter screen.

[0065] Optionally, the first working mode is a normal cleaning operation mode of the pool cleaning device, and the second working mode is a filter cleaning mode of the pool cleaning device.

[0066] As an example, the method may further include: in the second working mode, stopping driving water flow into / out of the water cleaning chamber by at least one first driving component of the pool cleaning device.

[0067] As an example, the method may further include: when the second operating mode operates for a time threshold, the at least one second driving component stops driving the filter unit to vibrate, and the pool cleaning device exits the second operating mode.

[0068] As an example, Figure 8 As shown, the method further includes: S810, in the first working mode, locking the filter unit and the water cleaning chamber of the pool cleaning device; S820, in the second working mode, releasing the lock between the filter unit and the water cleaning chamber.

[0069] As an example, Fig. 9 As shown, the above method also includes: S910, detecting the blockage condition of the filter unit; S920, based on the detection result, determining whether to exit the first working mode and enter the second working mode.

[0070] Optionally, detecting the clogging condition of the filter unit may include detecting a driving power of the at least one first driving component and / or detecting a state of water flow in / out of the pool cleaning device.

[0071] As an example, the at least one driving component includes a water pump, wherein the water pump includes a pump motor and an impeller; optionally, detecting the driving power of the at least one first driving component includes detecting at least one of the following: the current and voltage when the pump motor is running, and the revolutions per minute when the impeller is running.

[0072] As an example, detecting the state of the water flow in / out of the pool cleaning device includes detecting at least one of the following: the pressure of the water flow in / out of the pool cleaning device, and the flow rate of the water flow in / out of the pool cleaning device.

[0073] According to the pool cleaning device and the corresponding method of the embodiment of the present disclosure, the filter unit of the pool cleaning device can be automatically cleaned to avoid clogging of the filter screen of the filter unit due to dirt / garbage collected after filtering the water. The cleaning efficiency of the pool cleaning device can be improved and the labor and time costs of cleaning the pool cleaning device can be reduced.
