[0041] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0042] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. In the description of the present application, the orientations or positional relationships such as "top" and "bottom" are based on the orientations or positional relationships when the cooking device is in normal use. It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The descriptions such as "first" and "second" in the embodiments of the present application are for descriptive purposes only, and cannot be understood as indicating or implying their relative importance or implicitly including at least one feature. In the description of the embodiments of the present application, the meaning of "multiple" is at least two, that is, including two and more than two, such as two or three, etc., unless otherwise clearly and specifically defined.

[0043] According to a first aspect of an embodiment of the present application, a cleaning base station is provided, comprising a base station body, a first detection device, a fan and a control device.

[0044] The base station body has a dust collection port and a dust collection air duct. The dust collection port is used to receive debris discharged by a cleaning robot, such as a sweeper, a floor scrubber, a sweeper-mop machine, etc.

[0045] It can be understood that debris refers to garbage, dust, etc. that are absorbed by the cleaning robot.

[0046] Exemplarily, the cleaning robot is equipped with a dust box for accommodating debris, and the dust exhaust port is arranged on the dust box.

[0047] The fan is used to make the airflow in the dust collecting duct produce directional flow.

[0048] Exemplarily, the fan is disposed in the base station body, and a garbage storage chamber and a dust collection duct are arranged inside the base station body, and the dust collection duct is connected to the dust collection port and the garbage storage chamber. When the cleaning robot needs to discharge dust, the fan is started, and negative pressure is formed in the dust collection duct. Since the dust collection port is connected to the dust discharge port, negative pressure is also formed in the dust box of the cleaning robot. Under the action of negative pressure, the debris in the dust box is sucked into the dust collection duct and then temporarily stored in the garbage storage chamber.

[0049] The first detection device is arranged on the base station body, and is used for detecting the amount of debris passing through the dust collecting air duct and generating a detection signal.

[0050] The type of the first detection device is not limited. For example, the first detection device may be an infrared sensor, a laser radar system, or an ultrasonic sensor.

[0051] In one embodiment, the first detection device is an infrared sensor installed in the dust collecting air duct, with one end being a transmitting end and the other end being a receiving end. The transmitting end emits infrared light waves, which scatter light after irradiating the debris. After the receiving end collects the light, it compares the changes in the light before and after to calculate the amount of debris.

[0052] In another embodiment, the first detection device is an ultrasonic sensor, including a transmitter and a receiver. The transmitter transmits an ultrasonic signal to the dust collecting air duct, and starts timing at the same time as the ultrasonic wave is transmitted. The ultrasonic wave propagates through the air, and will immediately reflect and propagate back when it encounters debris during the propagation. The ultrasonic receiver immediately stops timing when it receives the reflected wave, and calculates the amount of debris based on the fluctuation of the duration.

[0053] The control device is arranged on the base body, and is used for adjusting the working state of the fan according to the detection signal after the fan is turned on.

[0054] In one embodiment, the control device is configured to:

[0055] Make sure the cleaning robot enters the dust removal stage and starts the fan;

[0056] Obtaining the amount of debris in the dust collecting air duct based on the detection signal;

[0057] If the amount of debris in the dust collecting duct is not higher than the first threshold, turn off the fan. If the amount of debris in the dust collecting duct is higher than the first threshold and not higher than the second threshold, reduce the speed of the fan. If the amount of debris in the dust collecting duct is higher than the second threshold, increase the speed of the fan.

[0058] It can be understood that the first threshold is smaller than the second threshold.

[0059] Exemplarily, the control device may be a single chip microcomputer, a microprocessor, a control IC (integrated circuit), etc., and the first detection device and the control device may be wirelessly connected or electrically connected.

[0060] The wireless connection method may be a WIFI (wireless fidelity) connection, an NFC (Near Field Communication) connection, or a Bluetooth connection.

[0061] In one embodiment, the first detection device is wirelessly connected to the control device, and no wiring is required, thus saving costs.

[0062] It is understandable that after the cleaning robot enters the dust discharge stage, the dust collection port and the dust discharge port are connected, the fan is turned on, and the cleaning base station enters the dust collection stage, and the debris of the cleaning robot is sucked through the dust collection air duct. The control device adjusts the working state of the fan according to the detection signal during the dust collection process of the cleaning device. That is to say, before the control device is adjusted, the initial working state of the fan is the on state.

[0063] The cleaning base station provided in the embodiment of the present application adjusts the working state of the fan by detecting the amount of debris in the dust collection duct, dynamically adjusts the dust collection time, and can adjust the exhaust volume of the fan according to the amount of debris, saving energy. It can be understood that compared with the dust collection of the fan with a fixed time, the present application can shut down the fan in advance or reduce the fan speed when the amount of debris is small, saving the ineffective work loss of the fan; when the amount of debris is large, the fan operation time can be extended or the speed can be increased, instead of running the fan again after the user finds that the debris has not been cleaned up after the fan stops working, which improves the intelligence of the fan operation and the dust collection efficiency, and also improves the user experience of the debris cleaning operation, saving energy.

[0064] In one embodiment, the base station body includes a body and a base for carrying the cleaning robot that are connected to each other.

[0065] The specific connection method between the base station body and the base is not limited, and can be connected in a non-detachable manner, such as welding, riveting, etc.; or can be detachably connected, such as snap connection, screw connection, bolt connection, etc.

[0066] Exemplarily, the base is detachably connected to the base station body. In this embodiment, during the design of the base station body, when the size or position of the dust exhaust port of the cleaning robot changes locally, it is only necessary to update the design of the corresponding base or body, without the need to update the design of both the base and the body simultaneously. This can reduce product design costs, increase the commonality of parts between base station bodies of different models, and reduce the company's inventory pressure of stagnant materials.

[0067] The dust collecting port and the first detection device are not limited in their locations. It is understandable that at least part of the first detection device is located in the dust collecting air duct.

[0068] In one embodiment, the dust collection port is arranged on a side of the fuselage close to the base, and the first detection device is arranged on the fuselage. That is to say, the dust collection air duct is arranged inside the fuselage. In this embodiment, only wires need to be buried on the base, the structure is relatively simple, the thickness of the base can be controlled to a small size, and when different bases are matched with the fuselage, only the wire connection needs to be considered.

[0069] In another embodiment, the dust collection port and the first detection device are arranged on the base. That is, the dust collection air duct is arranged on the base. In this way, during the dust removal stage of the cleaning robot, some large debris falls directly into the garbage receiving cavity by its own gravity, thereby improving the dust collection efficiency of the cleaning base station.

[0070] In one embodiment, a slope for guiding the cleaning robot to enter or leave the base is provided at one end of the base away from the body. It is understandable that the base has a certain thickness, and the slope can facilitate the cleaning robot to enter or leave the base more easily and smoothly.

[0071] A second aspect of an embodiment of the present application provides a cleaning system, including a cleaning base station and a cleaning robot.

[0072] The cleaning base station comprises a base station body, a fan and a control device. The base station body is provided with a dust collecting port and a dust collecting air duct.

[0073] The cleaning robot comprises a second detection device and a dust box having a dust discharge port. That is to say, in this embodiment, the second detection device is arranged on the cleaning robot.

[0074] The dust collecting port is used to receive the debris discharged from the dust discharging port, and the fan is used to make the airflow of the dust collecting duct produce a directional flow, so that the debris in the dust box is sucked into the dust collecting duct under the action of negative pressure and then temporarily stored in the garbage containing cavity.

[0075] It should be noted that when the cleaning robot is cleaning the floor, the space in the dust box can be at positive pressure or negative pressure, and there is no restriction here. It should be noted that when the cleaning robot is cleaning the floor, the dust outlet is in a closed state, and the airflow in the dust box basically does not escape from the dust outlet.

[0076] It is understandable that the volume of the garbage holding chamber is larger than the volume of the dust box, so it can accommodate the debris collected by the cleaning robot when performing multiple cleaning tasks. The user only needs to concentrate on cleaning the debris in the garbage holding chamber of the cleaning base station, without having to clean the dust box of the cleaning robot every time.

[0077] The second detection device is used to detect the amount of debris in the dust box and generate a detection signal.

[0078] The control device is used to adjust the working state of the fan according to the detection signal generated by the second detection device after the fan is turned on.

[0079] In one embodiment, the control device is configured to:

[0080] Determining that the cleaning robot enters the dust removal stage, and starting the fan;

[0081] Obtaining the amount of debris in the dust box based on the detection signal;

[0082] If the amount of debris in the dust box is not higher than the first threshold, turn off the fan. If the amount of debris in the dust box is higher than the first threshold and not higher than the second threshold, reduce the speed of the fan. If the amount of debris in the dust box is higher than the second threshold, increase the speed of the fan.

[0083] It can be understood that the control device is wirelessly connected to the second detection device.

[0084] Exemplarily, the control device and the second detection device may be connected in a WIFI connection, an NFC connection, a Bluetooth connection, or the like.

[0085] The cleaning system provided in the embodiment of the present application adjusts the working state of the fan by detecting the amount of debris in the dust box, dynamically adjusts the dust collection time, and can adjust the exhaust volume of the fan according to the amount of debris. The present application can shut down the fan in advance or reduce the fan speed when the amount of debris is small, saving the ineffective work loss of the fan; when the amount of debris is large, the fan operation time can be extended or the speed can be increased, instead of running the fan again after the user finds that the debris has not been cleaned up after the fan stops working. This improves the intelligence of the fan's operation and the dust collection efficiency, and also improves the user experience of the debris cleaning operation, saving energy.

[0086] The type of the second detection device is not limited. For example, the second detection device can be an infrared sensor, a laser radar system, a weight sensor, or an ultrasonic sensor.

[0087] In one embodiment, the second detection device may be a video monitoring device. That is, the image in the dust box is collected by a camera of the video monitoring device, and the collected image in the dust box is automatically identified by using machine learning technology to determine the debris in the dust box.

[0088] It is understandable that the second detection device is disposed at different locations depending on the type of the second detection device.

[0089] In one embodiment, the second detection device is disposed in the dust box. For example, the second detection device is an infrared sensor, including a transmitting end and a receiving end, which is fixedly installed in the dust box. Negative pressure is formed in the dust box of the cleaning robot. When the debris is discharged through the dust outlet, the transmitting end emits infrared light waves, which are scattered after being irradiated by the debris. After the receiving end collects the light, the amount of debris is calculated by comparing the changes in the light before and after.

[0090] In another embodiment, the second detection device is disposed outside the dust box. For example, the second detection device is a weight sensor, which calculates the amount of debris by detecting the weight change of the dust box.

[0091] It should be noted that the cleaning base station in the embodiment of the present application may be the cleaning base station in any of the above embodiments, or may be other cleaning base stations.

[0092] Exemplarily, the cleaning base station is a cleaning base station in any of the above embodiments. The cleaning system can detect the amount of debris in the dust collection duct through the first detection device, and detect the amount of debris in the dust box through the second detection device, and then adjust the exhaust volume of the fan according to the detection results of the first detection device and the second detection device, thereby improving the dust collection efficiency and user experience. In this way, compared with only setting the second detection device, the situation where the fan stops working when the debris in the dust box is exhausted and the debris is located in the dust collection duct is reduced, thereby improving the dust collection effect. At the same time, when one of the first detection device and the second detection device fails, it will not affect the normal operation of the control device, and the user can be informed of timely maintenance according to the detection results, thereby improving the user experience.

[0093] The specific structural form of the cleaning robot is not limited.

[0094] Exemplarily, the cleaning robot includes a body and a plurality of travel driving wheels protruding from the bottom side of the body. The body is roughly disc-shaped. The number of travel driving wheels is not limited, and can be two or more than two. In the present application, the number of travel driving wheels is two, and the two travel driving wheels are coaxially arranged. It should be noted that the coaxial arrangement of the two travel driving wheels means that when the two travel driving wheels are circular wheels, the rotation center lines of the two travel driving wheels are on the same straight line; when the two travel driving wheels are tracked wheels, the rotation center lines of the driving wheels of the two tracked wheels are located on a first straight line, and the rotation center lines of the driven wheels of the two tracked wheels are located on a second straight line, and the first straight line and the second straight line are spaced apart and parallel to each other.

[0095] Exemplarily, the cleaning robot includes a universal wheel protruding from the bottom side of the body, the universal wheel is located in front of the rotation axis of the travel drive wheel, and the universal wheel plays the role of supporting the body and steering. The number of universal wheels can be one or two. Exemplarily, the number of universal wheels is one. The universal wheel can be located on the midline of the line connecting the rotation centers of the two travel drive wheels, or it can deviate from the midline by a small distance. The two travel drive wheels and one universal wheel form a three-point stable support for the body. Among them, the two travel drive wheels are driving wheels, and the universal wheel is a driven wheel.

[0096] The dust box is detachably arranged on the machine body. The user can remove the dust box from the machine body for cleaning, washing, etc. according to the use needs.

[0097] The bottom surface of the machine body is provided with a dust suction port, and the cleaning robot comprises a roller brush, and the bristles of the roller brush extend from the dust suction port. Exemplarily, the roller brush extends in the left and right directions of the machine body.

[0098] The dust box is provided with an air inlet and an air extraction port, and the air inlet is connected to the dust suction port. When the sweeping robot performs the cleaning operation, the fan and other devices continuously suck air from the air extraction port, so that negative pressure is formed in the dust box, and then a negative pressure environment is formed around the dust suction port, and the dust, hair and other garbage on the ground are sucked into the dust box and intercepted in the dust box.

[0099] It can be understood that the dust box can be set at any appropriate position of the body, for example, at the tail of the body. In this embodiment, the dust box and the body together constitute the circumferential contour of the cleaning robot; in other embodiments, an installation cavity for accommodating the dust box is provided at a position approximately in the middle of the body along the front-to-back direction, and the dust box can be placed in the installation cavity from the top of the body, or taken out of the installation cavity. In this embodiment, the circumferential contour of the body is the circumferential contour of the cleaning robot.

[0100] Exemplarily, a top cover is provided on the top of the dust box, and the user takes out the dust box, opens the top cover, dumps out the debris inside the dust box, or rinses the dust box, etc. In other words, the cleaning robot can autonomously discharge dust through the cleaning base station, and can also be used by users for manual dust discharge and cleaning.

[0101] In one embodiment, the top surface of the cleaning base station base is provided with an anti-skid protrusion array, which extends to the slope. When the cleaning robot drives in or out of the base, the walking drive wheels always run on the anti-skid protrusion array to reduce the possibility of slipping of the walking drive wheels.

[0102] For the third aspect of the embodiment of the present application, please refer to Figure 1 , provides a control method for a cleaning system, comprising:

[0103] S1, determine that the cleaning robot enters the dust removal stage, and start the dust collection fan of the cleaning base station;

[0104] S2, obtaining the amount of debris at a preset location;

[0105] S3. Adjusting the working state of the dust collecting fan based on the amount of debris.

[0106] In step S1, the dust collecting fan may be the fan in the above embodiment. The cleaning robot enters the dust discharge stage when the dust discharge port of the cleaning robot is opened and the dust collecting port of the cleaning base station is connected to the dust discharge port of the cleaning robot.

[0107] The present application adjusts the working state of the dust collection fan during the dust removal stage of the cleaning robot, dynamically adjusts the dust collection time, and can adjust the exhaust volume of the fan according to the amount of debris. The present application can shut down the fan in advance or reduce the fan speed when the amount of debris is small, saving the ineffective work loss of the fan; when the amount of debris is large, the fan operation time can be extended or the speed can be increased, instead of running the fan again after the user finds that the debris has not been cleaned up after the fan stops working. This improves the intelligence of the fan's operation and the dust collection efficiency, and also improves the user experience of the debris cleaning operation and saves energy.

[0108] It is understandable that the cleaning robot needs to enter the dust removal stage after cleaning for more than a preset time.

[0109] In some embodiments, when the use time of the roller brush exceeds a first preset time, the cleaning robot needs to enter the dust removal stage; in other embodiments, when the suction time of the suction port exceeds a second preset time, the cleaning robot needs to enter the dust removal stage. The first preset time and the second preset time can be the same or different, corresponding to different cleaning modes.

[0110] In step S1, the method for determining whether the cleaning robot enters the dust removal stage is not limited.

[0111] In one embodiment, the cleaning robot enters the dust discharge stage by opening and closing the dust collection air duct of the cleaning base station, or by connecting the dust collection port and the dust discharge port. For example, in some embodiments, the cleaning robot enters the dust discharge stage when the dust collection air duct of the cleaning base station is detected to be open; in other embodiments, the cleaning robot enters the dust discharge stage when the dust discharge port of the cleaning robot is connected to the dust collection port of the cleaning base station.

[0112] In another embodiment, the cleaning robot enters the dust removal stage through the in-place detection of the cleaning robot, wherein the in-place detection refers to detecting whether the cleaning robot is at a target position. The target position refers to the position of the cleaning robot when the dust removal port of the cleaning robot is connected to the dust collection port of the cleaning base station.

[0113] In one embodiment, the cleaning system includes a sensing mechanism for detecting the presence of the cleaning robot.

[0114] Specifically, in some embodiments, the sensing mechanism includes a first electrode sheet and a second electrode sheet. The first electrode sheet is arranged on a cleaning base station, and a first sensing circuit electrically connected to the first electrode sheet is arranged on the cleaning base station. The second electrode sheet is arranged on a cleaning robot, and a second sensing circuit electrically connected to the second electrode sheet is arranged on the cleaning robot. When the electrode sheets on the two are connected, the first sensing circuit and the second sensing circuit are connected, and a sensing signal indicating that the cleaning robot is at the target position is sent to the control device.

[0115] In other embodiments, the sensing mechanism includes a position sensor, such as an infrared sensor. A transmitting component of the infrared sensor can be installed on one of the cleaning base station and the cleaning robot, and a receiving component of the infrared sensor can be installed on the other. When the receiving component receives the infrared ray emitted by the transmitting component, a sensing signal indicating that the cleaning robot is at the target position is sent to the control device.

[0116] In this way, after receiving the sensing signal, the control device controls the cleaning base station to collect dust from the cleaning robot, that is, starts the dust collecting fan, so as to clean up the debris accumulated by the cleaning robot in a timely and accurate manner.

[0117] Exemplarily, the preset position in S2 includes a dust box of the cleaning robot and / or a dust collection duct of the cleaning base station. That is, in some embodiments, the preset position includes a dust box of the cleaning robot, in other embodiments, the preset position includes a dust collection duct of the cleaning base station, and in still other embodiments, the preset position includes a dust box of the cleaning robot and a dust collection duct of the cleaning base station.

[0118] It is understandable that the amount of debris in the dust box and the dust collection duct can reflect the adjustment requirements of the dust collection fan. Furthermore, by obtaining the amount of debris in the dust box of the cleaning robot and the dust collection duct of the cleaning base station, the situation where the fan stops working when the debris in the dust box is completely removed and the debris is in the dust collection duct is reduced, thereby improving the dust collection effect. At the same time, when one of the two detection devices fails, it will not affect the adjustment of the dust collection fan, and the user can be informed of timely maintenance based on the detection results, thereby improving the user experience.

[0119] In step S2, the amount of debris may refer to the flow rate in the dust collection duct or the mass of debris in the dust box. Exemplarily, the preset position is the dust box of the cleaning robot, and the detection device is a weighing sensor. It is understandable that in order to obtain a larger range of the weighing sensor, the dust box without debris is zero-calibrated.

[0120] In one embodiment, please refer to Figure 2 , S3 includes: if the amount of debris at the preset position is not higher than the first threshold, turning off the dust collecting fan; if the amount of debris at the preset position is higher than the first threshold, maintaining the dust collecting fan to continue running.

[0121] Among them, the first threshold value can be a pre-set value for characterizing the amount of debris. Specifically, the first threshold value can be 0, that is, after the dust collecting fan is turned on, the amount of debris at the preset position is detected by the detection device. If the amount of debris at the preset position is not higher than 0, it means that there is no debris at the preset position, and the debris in the dust box of the cleaning robot has been completely discharged. At this time, the dust collecting fan is turned off by the control device, which saves energy and extends the service life of the dust collecting fan; if the amount of debris at the preset position is higher than 0, it means that there is debris at the preset position, and there is still undischarged debris in the dust box of the cleaning robot, and the dust collecting fan is maintained to continue running to discharge the remaining debris. In this way, the dust collecting fan is adjusted according to the current dust discharge needs of the cleaning robot, which is intelligent and convenient, and improves the user experience.

[0122] It can be understood that the working state of the dust collecting fan can refer to either the opening and closing of the dust collecting fan or the rotation speed of the dust collecting fan.

[0123] In one embodiment, the working state of the dust collecting fan includes the start and stop of the dust collecting fan and / or the speed of the dust collecting fan. Exemplarily, the working state of the dust collecting fan can be the start and stop of the dust collecting fan, the speed of the dust collecting fan, or the start and stop of the dust collecting fan and the speed of the dust collecting fan. In other words, this embodiment can adjust the exhaust volume of the dust collecting fan by controlling the start and stop of the dust collecting fan and / or controlling the speed of the dust collecting fan.

[0124] In this embodiment, S3 includes:

[0125] If the amount of debris at the preset position is not higher than the second threshold, reducing the speed of the dust collecting fan;
