[0018] Representative embodiments embodying the features and advantages of the present disclosure are described in detail in the following description. It should be understood that the present disclosure may be modified in various ways in different embodiments without departing from the scope of the present disclosure, and the description therein and the accompanying drawings are used for illustrative purposes only and are not intended to limit the present disclosure.

[0019] Different exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, which form a part of the present disclosure and which exemplarily show different exemplary structures, systems and steps in multiple aspects that can realize the present disclosure. It should be understood that other specific solutions of members, structures, exemplary devices, systems and steps can be used, and structural and functional changes can be made without departing from the scope of the present disclosure. Furthermore, although terms such as "on", "between", and "within" are used in this specification to describe different exemplary features and elements of the present disclosure, these terms are used herein for convenience, for example, according to the exemplary directions in the accompanying drawings. Nothing in this specification should be understood as requiring a specific three-dimensional orientation of a structure to fall within the scope of the present disclosure.

[0020] As shown in FIGS. 1 to 17 , the cleaning robot includes a device body 10, a cleaning system 20, a driving system 30, a collection system 40, a sealing assembly 50, a detection system 60, a sensing system 70, a control system 80, an energy system 90 and a man-machine interactive system 100.

[0021] As shown in FIG. 1, device body 10 includes a front portion 12 and a rear portion 13 and has a generally circular shape (wherein both the front and rear are circular), but may have other shapes, including, but not limited to, a generally D-shape where the front is square and the rear is circular, and a rectangular or square shape where both the front and rear are square.

[0022] 1, the sensing system 70 includes a positioning device 71 on the device body 10, a collision sensor provided on a shock absorber 72 in the front part 12 of the device body 10, a short-distance sensor on the device body 10, a cliff sensor provided on the bottom of the device body, and sensing devices such as a magnetometer, an accelerometer, a gyroscope, and an odometer provided inside the device body 10, and is used to provide various position information and moving state information of the device to the control system 80. The positioning device 71 includes, but is not limited to, a camera and a laser distance sensor (LDS).

[0023] As shown in FIG. 1, a buffer 72 may be mounted on the front part 12 of the machine body 10. When the drive system 30 propels the cleaning robot to run on the floor surface during the cleaning process, the buffer 72 detects one or more events in the running path of the cleaning robot through a collision sensor provided thereon. Depending on the event detected by the buffer 72, e.g., an obstacle or a wall, the cleaning robot can control the drive system 30 so that the cleaning robot responds to the event, e.g., moves away from the obstacle.

[0024] The control system 80 is provided on the main circuit board in the device body 10, and includes a computing processor such as a central processing unit and an application processor, which communicates with a non-transient memory such as a hard disk, a flash memory, and a random access memory. The application processor uses a positioning algorithm, such as SLAM (Simultaneous Localization And Mapping), based on the obstacle information fed back from the laser distance measuring device to draw a real-time map of the environment where the cleaning robot is located. Then, in combination with the distance information and speed information fed back from the sensing devices such as the sensor, cliff sensor, magnetometer, accelerometer, gyroscope, and odometer provided on the buffer 72, the control system 80 comprehensively judges the current operating state, current position, and current posture of the cleaning robot, such as crossing a threshold, climbing a carpet, being on a cliff, being caught above or below, the dust box being full, being lifted, etc., and gives specific next operating strategies according to different situations, so that the cleaning robot has better cleaning performance and user experience.

[0025] As shown in FIG. 2 and FIG. 3, the drive system 30 controls the machine body 10 to run across the floor surface based on a drive command including distance and angle information (e.g., x, y, and θ components). The drive system 30 may include a first drive wheel module 31 and a second drive wheel module 32. The first drive wheel module 31 and the second drive wheel module 32 are provided along a horizontal axis defined by the machine body 10. In order for the cleaning robot to move more stably on the floor surface or have a higher moving ability, the cleaning robot may include one or more driven wheels 33, including but not limited to universal wheels. The drive wheel module includes a running wheel, a drive motor, and a control circuit for controlling the drive motor, and the drive wheel module may be connected to a circuit for measuring a drive current and an odometer. The drive wheel module is detachably connected on the machine body 10 for attachment / detachment and maintenance. The drive wheel may include an offset drop type suspension system, and is movably fixed, for example rotatably attached to the machine body 10, and receives a spring offset offset downwardly away from the machine body 10. The spring offset allows the drive wheels to maintain contact and traction with the floor surface with a constant floor adhesion force while the cleaning elements of the cleaning robot also contact the floor surface with a constant pressure.

[0026] The device body 10 defines a lateral axis and a longitudinal axis, which are perpendicular to one another and which may be understood as the lateral and longitudinal centerlines of the device body 10, respectively. The energy system 90 includes a rechargeable battery such as a nickel-metal hydride battery and a lithium battery. A charging control circuit, a battery pack charging temperature detection circuit, and a battery voltage shortage monitoring circuit are connected to the rechargeable battery, and the charging control circuit, the battery pack charging temperature detection circuit, and the battery voltage shortage monitoring circuit are connected to a one-chip microcomputer control circuit. The cleaning robot may be connected to a charging pile for charging via a charging electrode provided on the main body, for example, on the side, bottom, or top of the main body.

[0027] The man-machine interaction system 100 includes keys on a host panel, which are used for a user to select functions, a display and / or an indicator lamp and / or a horn, which are used for indicating the current device status or function options to the user, and further includes a mobile phone client program. In the case of the path navigation automatic cleaning device 10, the mobile phone client can show the user a map of the device's environment and the device's location, providing the user with more abundant and user-friendly function options.

[0028] In the cleaning robot provided by the embodiment of the present disclosure, the cleaning system 20 is installed on the device body 10, the cleaning system 20 includes a cleaning head 21, and the horizontal axis of the device body 10 forms a preset included angle with the cleaning head 21, which can reduce the probability that the cleaning head 21 is caught by the joint when the cleaning robot passes through a floor environment such as a tile joint during the forward movement of the cleaning robot, thereby improving the cleaning efficiency of the cleaning robot and the usage performance of the cleaning robot. The preset included angle between the horizontal axis and the cleaning head 21 may be an acute angle, and the preset included angle may be in the range of 5 degrees to 70 degrees.

[0029] In an embodiment of the present disclosure, the cleaning system 20 may be a dry cleaning system, and the dry cleaning system may include a cleaning head 21, a dust box, a fan, an air outlet, etc. In an embodiment of the present disclosure, the cleaning head 21 may be a roller brush that can rotate around an axis parallel to the floor surface, and the roller brush having a certain interference with the floor surface sweeps up the dust on the floor surface and lifts it up in front of the dust suction port between the roller brush and the dust box, and then sucks it into the dust box through the suction gas generated by the fan and passing through the dust box. The dust removal ability of the cleaning robot is characterized by the dust pickup efficiency (DPU), and the cleaning efficiency DPU is affected by the roller brush structure and material, affected by the wind utilization rate of the air duct composed of the dust suction port, the dust box, the fan, the air outlet, and the connecting members between the four, and affected by the type and power of the fan, making it a complex system design problem.

[0030] In an embodiment of the present disclosure, the cleaning system 20 may be a wet cleaning system, the cleaning head 21 includes a wet cleaning head, and as shown in FIG. 4, the cleaning system 20 further includes a liquid supply 22, which supplies cleaning liquid to the wet cleaning head. The cleaning head 21 may be disposed below the liquid supply 22, and the cleaning liquid inside the liquid supply 22 is transported to the cleaning head 21 through a water supply mechanism, and the cleaning head 21 performs wet cleaning on the plane to be cleaned. In another embodiment of the present disclosure, the cleaning liquid inside the liquid supply 22 may be directly sprayed onto the plane to be cleaned, and the cleaning head 21 may evenly apply the cleaning liquid to achieve cleaning of the plane.

[0031] In the embodiment of the present disclosure, the cleaning head 21 is provided at the bottom of the device body 10, for example, the cleaning head 21 may be a cleaning pad parallel to the surface to be cleaned. In this embodiment, the cleaning head 21 is used to clean the surface to be cleaned, and the driving system 30 drives the cleaning head 21 to move back and forth basically along the target surface, the target surface being a part of the surface to be cleaned. The cleaning head 21 moves back and forth along the surface to be cleaned, and a cleaning cloth or cleaning plate is provided on the contact surface of the cleaning head 21 with the surface to be cleaned, and the back and forth movement generates high-frequency friction between the cleaning head 21 and the surface to be cleaned, thereby removing dirt on the surface to be cleaned.

[0032] The higher the friction frequency, the more the number of frictions per unit time, and the high-frequency reciprocating movement is also called reciprocating vibration, and the cleaning ability is much higher than ordinary reciprocating movements such as rotation, friction cleaning, and the like; optionally, the friction frequency is close to sound waves, and the cleaning effect is much higher than the rotation friction cleaning of tens of revolutions per minute. On the other hand, the tufts on the surface of the cleaning head 21 are neatly spread in the same direction under the vibration of high-frequency vibration without the friction force increasing only under the downward pressure under the circumstances of low-frequency rotation, so that the cleaning effect is more uniform as a whole, and the cleaning effect is improved, and the tufts do not spread in almost the same direction only under the downward pressure, and in terms of effect, the water stains on the surface to be cleaned after cleaning by high-frequency vibration are more uniform, and no chaotic water stains are left behind. In other embodiments of the present disclosure, the cleaning head 21 may be a belt-like structure, etc. In an embodiment of the present disclosure, as shown in FIG. 16, the cleaning head 21 may be a roller brush that can rotate around an axis parallel to the surface to be cleaned. The device body 10 includes a fixed bracket 11, a cleaning head 21 is located within the fixed bracket 11, a liquid supply passage is provided on the fixed bracket 11, and a liquid supply part 22 supplies cleaning liquid to the wet cleaning head through the liquid supply passage.

[0033] The liquid supply passage may be constituted by a cavity formed inside the fixed bracket 11, for example by providing a part of the fixed bracket 11 to be hollow, forming a liquid supply passage through which the cleaning liquid flows. The liquid supply passage may be formed by a tube, which supplies the cleaning liquid in the liquid supply 22 onto the wet cleaning head, thereby enabling the cleaning head 21 to effectively clean the surface to be cleaned.

[0034] In an embodiment of the present disclosure, as shown in Figures 8 and 9, the liquid supply passage has a liquid inlet 111 and a liquid outlet 112, the liquid inlet 111 communicating with the liquid supply 22 and the liquid outlet 112 being used to supply cleaning liquid to the cleaning head 21.

[0035] In an embodiment of the present disclosure, as shown in Figures 8 and 9, a liquid inlet 111 and a liquid outlet 112 are provided on the fixed bracket 11, one end of the liquid inlet 111 is located on the outer surface of the fixed bracket 11, and the liquid outlet 112 is located on the inner surface of the fixed bracket 11, and a main body portion of a liquid supply passage is provided between the liquid inlet 111 and the liquid outlet 112, and the main body portion is simultaneously connected to multiple liquid outlets 112, so that the liquid outlet 112 is used to supply cleaning liquid to the cleaning head 21.

[0036] In an embodiment of the present disclosure, a storage chamber 113 is formed in the fixed bracket 11, and a liquid outlet 112 is provided on a hollow wall of the storage chamber 113, and the liquid outlet 112 may be located at the top end of the storage chamber 113, or the liquid outlet 112 may be located at the side of the storage chamber 113, so that the cleaning liquid delivered from the liquid outlet 112 is reliably supplied to the cleaning head 21.

[0037] In an embodiment of the present disclosure, the liquid outlets 112 may be multiple, and the multiple liquid outlets 112 are spaced apart along a direction parallel to the cleaning head 21, so that cleaning liquid is uniformly supplied to each position of the wet cleaning head, and the wet cleaning head can reliably clean the surface to be cleaned.

[0038] The liquid supply passage may have one liquid inlet 111 , which corresponds to all the liquid outlets 112 .

[0039] As an optional embodiment of the present disclosure, the liquid supply passage may have at least two liquid inlets 111, each of which corresponds to a plurality of liquid outlets 112, to ensure that the cleaning liquid is supplied onto the wet cleaning head. The liquid inlets 111 may be formed by a columnar structure to be connected to a tubular structure for supplying the cleaning liquid. The liquid outlets 112 may be rectangular, circular or other polygonal structures, and are not particularly limited here. The plurality of liquid outlets 112 are sequentially provided along a direction parallel to the cleaning head 21.

[0040] In an embodiment of the present disclosure, as shown in Figures 5 and 6, a collection system 40 is provided on the device body 10, and the collection system 40 includes a collection section 41, which collects residues on the cleaning head 21 and / or the surface to be cleaned, thereby effectively cleaning the surface to be cleaned and ensuring the cleanliness of the surface to be cleaned.

[0041] During the movement process of the cleaning robot, the cleaning head 21 rotates to clean the surface to be cleaned, during this process, residues on the surface to be cleaned are adsorbed onto the cleaning head 21, and the collecting unit 41 collects these residues to ensure the cleanliness of the cleaning head 21, and the collecting unit 41 collects the residues on the surface to be cleaned, thereby cooperating with the cleaning head 21 to achieve reliable cleaning of the surface to be cleaned. The residues may be water, dirt, etc., but are not limited thereto.

[0042] In an embodiment of the present disclosure, as shown in FIG. 3 , the recovery system 40 further includes a scraper 42, which contacts the cleaning head 21, and the scraper 42 can remove residues on the cleaning head 21 through interference with the cleaning head 21, which can be collected by the collection portion 41, to ensure the cleanliness of the cleaning head 21, and to ensure effective cleaning of the surface to be cleaned.

[0043] Specifically, the scraper 42 may be a plate-like structure that interferes with the cleaning head 21, and during the rotation process of the cleaning head 21, the plate-like structure removes residues on the cleaning head 21 and is collected by the collecting part 41, so that the residues adsorbed on the surface to be cleaned are surely collected by the collecting part 41. The scraper 42 may be provided on the device body 10. The scraper 42 is provided on the device body 10 in a detachable manner.

[0044] In the embodiment of the present disclosure, the scraper 42 is parallel to the cleaning head 21, which ensures that the scraper 42 removes any residue on the cleaning head 21 and allows for easy attachment of the structure.

[0045] Specifically, the length of the scraper 42 may be equal to the length of the cleaning head 21, and based on ensuring that the scraper 42 can fully interfere with the cleaning head 21, the scraper 42 can be prevented from occupying space in the longitudinal direction, and the compactness of the structure can be ensured.

[0046] In an alternative embodiment of the present disclosure, the lateral axis of the device body 10 is parallel to the cleaning head 21 and the lateral axis of the device body 10 is parallel to the scraper 42.

[0047] In an embodiment of the present disclosure, as shown in Figures 10 and 11, a water inlet 421 is provided on the scraper 42, the water inlet 421 is connected to the collection section 41, and the recovery system 40 ensures that the wastewater is collected in the collection section 41 through the water inlet 421.

[0048] Specifically, the suction port 421 may face the cleaning head 21, and after the scraper 42 scrapes off the wastewater on the cleaning head 21, the wastewater flows along the scraper 42 toward the suction port 421, and the recovery system 40 causes the wastewater to be sucked into the collection section 41 by the suction port 421.

[0049] As an optional embodiment of the present disclosure, the water inlet 421 may be provided on the side of the scraper 42 away from the cleaning head 21, and a part of the scraper 42 collects wastewater, and the water inlet 421 sucks the collected wastewater into the collection section 41.

[0050] In an embodiment of the present disclosure, as shown in Fig. 7, the recovery system 40 further includes a power unit 43, which is in air communication with the collection unit 41 and collects the residue in the collection unit 41. Negative pressure is generated between the power unit 43 and the collection unit 41 to suck the residue on the surface to be cleaned and the residue on the cleaning head 21 into the collection unit 41. Specifically, the negative pressure generated between the power unit 43 and the collection unit 41 sucks the wastewater into the collection unit 41 through the water inlet 421. The power unit 43 may be a fan.

[0051] In an embodiment of the present disclosure, as shown in FIG. 9 , a storage chamber 113 is formed in the fixed bracket 11, the cleaning head 21 is located in the storage chamber 113, and the collecting section 41 communicates with the storage chamber 113, so that the residue enters the collecting section 41 after passing through the storage chamber 113.

[0052] Specifically, a through hole 114 is provided on the fixed bracket 11, the through hole 114 communicates with the collecting unit 41, and the through hole 114 communicates with the storage chamber 113, so that the residue scraped off from the cleaning head 21 by the scraper 42 is located in the storage chamber 113 of the fixed bracket 11, and the residue in the storage chamber 113 is sucked into the collecting unit 41 through the through hole 114 due to the negative pressure generated between the power unit 43 and the collecting unit 41. As an optional embodiment of the present disclosure, the storage chamber 113 of the fixed bracket 11 forms a space that is relatively sealed with the surface to be cleaned, so that the residue on the surface to be cleaned is sucked into the collecting unit 41 through the through hole 114 due to the negative pressure generated between the power unit 43 and the collecting unit 41.

[0053] In the embodiment of the present disclosure, as shown in Fig. 7, the collecting unit 41 has an inlet 411 and an outlet 412, the inlet 411 communicates with the storage chamber 113, the inlet 411 may communicate with the through hole 114, and the outlet 412 may communicate with the power unit 43, and the power unit 43 provides power through the outlet 412 of the collecting unit 41 to suck the residue from the through hole 114 of the storage chamber 113 to the inlet 411 of the collecting unit 41 and enter the collecting unit 41. Here, when the airflow flows inside the collecting unit 41, the wastewater, garbage, etc. carried by the airflow are retained in the collecting unit 41 under the action of gravity, so that when the airflow path inside the collecting unit 41 is relatively long, the wastewater, garbage, etc. can be separated from the airflow.

[0054] In an embodiment of the present disclosure, as shown in FIG. 12, the inlet 411 and outlet 412 of the collection section 41 may be provided on the same side of the collection section 41, for example, the inlet 411 and outlet 412 of the collection section 41 may both be located on the front side of the collection section 41, thereby effectively extending the airflow path within the collection section 41, so that sewage, garbage, etc. can be more effectively separated from the airflow.

[0055] In an embodiment of the present disclosure, as shown in Figures 5 and 6, the sealing assembly 50 of the cleaning robot is provided on the equipment body 10, and the position of at least a part of the sealing assembly 50 is adjustable, so as to open and close the inlet 411 of the collecting section 41 and the outlet 412 of the collecting section 41, thereby preventing the garbage in the collecting section 41 from pouring out from the inlet 411 or entering the power section 43 from the outlet 412.

[0056] Specifically, the sealing assembly 50 can close the inlet 411 and outlet 412 of the collecting unit 41 during the non-operation process of the cleaning robot, so as to avoid the problem of the residue being accidentally poured out due to the manual movement of the cleaning robot. When the cleaning robot starts to operate, the sealing assembly 50 can open the inlet 411 and outlet 412 of the collecting unit 41, so that the residue is sucked into the collecting unit 41 from the inlet 411.

[0057] In the embodiment of the present disclosure, the sealing assembly 50 may be controlled by an independent motor, and may realize the closing control of the inlet 411 and the outlet 412 of the collecting section 41 at any time, for example, may close the cleaning robot under a non-operating state.

[0085] In the embodiment of the present disclosure, at least a part of the detection system 60 is movably provided with respect to the device body 10, so that the position of the detection system 60 can be reliably adjusted, and thus can be adapted to different application environments. The detection system 60 may be driven by a driving mechanism to realize the position adjustment, or the detection system 60 may include a flexible mechanism, and the position adjustment may be realized by deforming the flexible mechanism.

[0086] Specifically, the detection system 60 is telescopically provided on the device body 10, and has an extended state and a retracted state, and when the detection system 60 extends to the front of the cleaning robot, it can detect the floor surface condition in front of the cleaning robot. For example, when the cleaning robot is D-shaped, the detection system 60 may be provided near the corner of the cleaning robot, and when the detection system 60 is in the telescopic state, it can easily detect the floor surface condition in front or to the side.

[0087] Specifically, the driving system 30 can drive the cleaning robot to operate on the work surface, and at this time, the control system 80 can drive the detection system 60 to move from the stored state to the extended state, and the detection system 60 can monitor the state of the work surface in real time. Furthermore, since the detection system 60 has a detection viewing angle facing the work surface, it can accurately detect the state of the work surface, such as a change in the material of the work surface, a change in the horizontality of the work surface, or dirt detection.

[0088] In an embodiment of the present disclosure, as shown in FIGS. 1 to 3, the detection system 60 may be connected to a corner position of the device body 10, and the auxiliary cleaning head 23 is provided at a position close to the detection system 60 of the device body 10, and the detection system 60 can identify the surface to be cleaned early and determine the physical properties of the surface to be cleaned, such as the surface material, cleaning degree, etc., and the control system 80 can control the operating state of the auxiliary cleaning head 23 based on the identification result of the detection system 60 to ensure the cleaning function of the auxiliary cleaning head 23. For example, when the surface to be cleaned identified by the cliff sensor is a floor, the auxiliary cleaning head 23 can be controlled to increase the humidity to ensure the cleaning effect; or when the surface to be cleaned identified by the cliff sensor is a carpet, the auxiliary cleaning head 23 can be controlled to decrease the humidity to avoid wetting the carpet.

[0089] In the embodiment of the present disclosure, the detection system 60 is telescopically installed at the front part 12 of the appliance body 10, so that the detection system 60 can determine the condition of the surface to be cleaned early and feed back to the control system 80, and the control system 80 can adjust the travel path and cleaning mode of the cleaning robot according to the information fed back from the detection system 60. The detection system 60 is installed at a corner position of the front part 12, so that the detection system 60 can be reasonably arranged, avoiding the detection system 60 from occupying a relatively large area, and the detection system 60 can reliably monitor the condition of the working surface at the corner of the appliance body 10, so that the cleaning robot can clean the working surface more efficiently.

[0091] In an embodiment of the present disclosure, the control system 80 may be connected to the detection system 60, and the control system 80 may control the extension state of the detection system 60, for example, when the cleaning robot operates, the control system 80 may control the detection system 60 to move from the storage state to the extended state, or when the cleaning robot stops operating, the control system 80 may control the detection system 60 to move from the extended state to the storage state. Or, when the detection system 60 detects that the work surface has a recess or the work surface material changes, the control system 80 may control the cleaning system 20 or control the driving system 30 to change the operating state, the work surface being the surface to be cleaned. For example, when the detection system 60 detects that the work surface has a recess, the control system 80 may control the driving system 30 to decelerate, and the control system 80 may control the cleaning system 20 to rotate at a slower speed. For example, if the detection system 60 detects a change in the work surface material, such as changing from carpet to tile, then the control system 80 may control the drive system 30 to accelerate and the control system 80 may control the cleaning system 20 to accelerate and rotate.

[0092] The detection system 60 is used to detect changes in the material of the surface to be cleaned, changes in the horizontality of the surface to be cleaned, or dirt detection, and can feed back to the control system 80 to control the operating state of the cleaning robot. For example, if the detection system 60 detects that the surface to be cleaned is relatively dirty, the control system 80 controls the cleaning robot to slow down, so that the cleaning system 20 can clean the surface to be cleaned well. Or, if the detection system 60 detects that the surface to be cleaned is a floor, the control system 80 controls the water pump 24 to increase the flow rate of the cleaning liquid supplied from the liquid supply unit 22 to the cleaning head 21 and the auxiliary cleaning head 23, so as to ensure the cleaning of the floor. Or, the control system 80 can adjust the travel route and cleaning mode of the cleaning robot based on the information fed back from the detection system 60.

[0093] In the embodiment of the present disclosure, the detection system 60 may be provided in multiple numbers, which can effectively expand the detection range of the detection system 60 and accurately assist the operating state of the cleaning system 20 or the driving system 30.
