DETAILED DESCRIPTION

[0043] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present application. However, it will be apparent to those skilled in the art that the present application can be implemented without one or at least three of these details. In other examples, some technical features well known in the art are not described to avoid confusion with the present application.

[0044] It should be noted that the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, wholes, steps, operations, elements and / or components, but do not exclude the presence or addition of one or at least three other features, wholes, steps, operations, elements, components and / or combinations thereof.

[0045] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided to make the disclosure of this application thorough and complete and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0046] The cleaning device mentioned in the embodiment of the present application is a device that automatically performs cleaning operations in a certain area to be cleaned. It can be an automatic sweeping robot, an automatic mopping robot, etc. This embodiment does not strictly limit the structure of the cleaning device.

[0047] Specifically, as shown in FIG. 1 and FIG. 2 , the cleaning device includes a housing 110 , a sensing system, a control module, a driving system 130 , a cleaning system 140 and an energy system.

[0048] As shown in Figure 1, the shell 110 includes a forward part 111 and a rear part 112, which have an approximately circular shape (both the front and the back are circular), and may also have other shapes, including but not limited to an approximately D-shape with a front and a rear circle and a rectangular or square shape at the front and the back.

[0049] As shown in Figure 1, the perception system includes a position determination device located on housing 110, a collision sensor and a proximity sensor located on the bumper of the forward portion 111 of housing 110, a cliff sensor located below housing 110, and sensing devices such as a magnetometer, accelerometer, gyroscope, and odometer located within housing 110. These sensors provide the control module with various machine position and motion status information. Position determination devices include, but are not limited to, cameras and laser distance sensors (LDS).

[0050] As shown in Figure 1, the forward part 111 of the shell 110 can carry a buffer. When the driving wheel module 131 propels the cleaning device 100 to walk on the ground during the cleaning process, the buffer detects one or more events in the driving path of the cleaning device 100 through a sensor system arranged thereon, such as an infrared sensor. The cleaning device 100 can control the driving wheel module 131 to respond to the event, such as an obstacle or a wall, based on the event detected by the buffer.

[0051] The control module is disposed on a circuit board within the housing 110 and includes a computing processor, such as a central processing unit or an application processor, that communicates with a non-transitory memory, such as a hard disk, flash memory, or random access memory. The application processor utilizes a positioning algorithm, such as Simultaneous Localization and Mapping (SLAM), based on obstacle information fed back by the laser rangefinder to create a real-time map of the environment in which the cleaning device 100 is located. Furthermore, the application processor uses distance and speed information fed back by sensors, cliff sensors, magnetometers, accelerometers, gyroscopes, odometers, and other sensing devices disposed on the buffer to comprehensively determine the current operating state and location of the cleaning device 100, as well as its current posture, such as when the cleaning device 100 is crossing a threshold, on a carpet, on a cliff, stuck above or below, a full dust box, or being lifted up. Specific next-step action strategies are also provided for different situations, thereby providing the cleaning device 100 with better cleaning performance and user experience.

[0052] As shown in Figure 2, drive system 130 can be based on the driving command with distance and angle information such as x, y and theta component and manipulate cleaning equipment 100 to travel across the ground.Drive system 130 comprises drive wheel module 131, and drive wheel module 131 can control left and right wheel simultaneously, and in order to more accurately control the motion of machine, preferably drive wheel module 131 comprises left drive wheel module and right drive wheel module respectively.In order that cleaning equipment 100 can more stably move or stronger athletic ability on the ground, cleaning equipment 100 can comprise one or more driven wheels 132, and driven wheel 132 includes but is not limited to universal wheel.Drive wheel module 131 comprises running wheel and drive motor and the control circuit of control drive motor, and drive wheel module 131 can also be connected the circuit and the odometer of measurement driving current.

[0053] The energy system includes rechargeable batteries, such as nickel-metal hydride and lithium-ion batteries. These batteries can be connected to a charging control circuit, a battery pack charging temperature detection circuit, and a battery undervoltage monitoring circuit. These circuits are then connected to the microcontroller control circuit. The host computer is charged via charging electrodes located on the side or bottom of the device, connecting to the base station.

[0054] The cleaning system 140 includes a wet cleaning system, that is, the cleaning device 100 may be a mop, or the cleaning system 140 includes a wet cleaning system and a dry cleaning system 141, that is, the cleaning device 100 may be a sweeping and mopping machine.

[0055] As shown in Figure 2, the dry cleaning system 141 provided in this embodiment of the present application may include a roller brush, a dust box, a fan, and an air outlet. The roller brush, which has a certain degree of interference with the ground, sweeps up debris from the ground and carries it to the front of the dust suction port between the roller brush and the dust box. The air is then sucked into the dust box by the suction force generated by the fan and passing through the dust box. The dry cleaning system 141 may also include a side brush 142 with a rotating shaft that is angled relative to the ground to move debris into the roller brush area of ​​the cleaning system 140.

[0056] Among them, the wet cleaning system may include: a cleaning component, a water supply mechanism, a liquid storage tank, etc. Among them, the cleaning component can be arranged below the liquid storage tank, and the cleaning liquid inside the liquid storage tank is transmitted to the cleaning component through the water supply mechanism, so that the cleaning component performs wet cleaning on the surface to be cleaned. In other embodiments of the present application, the cleaning liquid inside the liquid storage tank can also be sprayed directly onto the surface to be cleaned, and the cleaning component cleans the surface by evenly applying the cleaning liquid. It is understandable that the cleaning device 100 is provided with a water injection port connected to the liquid storage tank, and the water injection port can be used to replenish the liquid outside the cleaning device 100 into the liquid storage tank to achieve a water replenishment operation on the liquid storage tank.

[0057] The cleaning assembly provided in the embodiment of the present application includes a motion mechanism and a cleaning element 143. The cleaning assembly moves along with the movement of the cleaning device 100 to achieve the mopping function. The motion mechanism is used to drive the cleaning element 143 to move. For example, the motion mechanism can drive the cleaning element 143 to rise and fall, and the motion mechanism can also drive the cleaning element 143 to rotate. Thus, the lifting and rotating operations of the cleaning element 143 can be achieved through the motion mechanism according to the requirement of whether the cleaning element 143 is in contact with the surface to be cleaned, so as to meet the different functional requirements of the cleaning element 143. That is, the processing of the distinguishing strategy of the cleaning element 143 can be realized, thereby improving the cleaning performance of the self-cleaning device, and improving the cleaning efficiency and user experience.

[0058] As shown in FIG2 , in the forward direction of the cleaning device 100, the cleaning element 143 is located at the rear of the dry cleaning system 141. The cleaning element 143 can typically be a flexible, absorbent material such as fabric or a sponge. In this embodiment, the cleaning element 143 can be at least one rotating turntable. Water in the robot's liquid tank is directed to the cleaning element 143. The wet cleaning element 143 removes stains from the floor through its rotational motion.

[0059] Furthermore, during the movement of the cleaning device 100, in some scenarios where mopping the floor is required, such as wet treatment of the floor, the control module can be used to control the motion mechanism to drive the cleaning element 143 to descend, so that the lowest lower surface of the cleaning element 143 interferes with the surface to be cleaned. At the same time, the control module is used to control the motion mechanism to drive the cleaning element 143 to rotate. As a result, when the driving wheel drives the cleaning device 100 to move, the cleaning element 143 will contact and interfere with the surface to be cleaned, so as to realize the mopping operation of the surface to be cleaned.

[0060] Furthermore, during the movement of the cleaning device 100, in some scenarios where mopping is not required, such as traveling to and from the base station 200, or performing carpet cleaning, the control module can be used to control the motion mechanism to drive the cleaning element 143 to rise. It can be understood that the cleaning element 143 can be raised so that the lowest lower surface of the cleaning element 143 is higher than the lowest lower surface of the driving wheel, so that in this case, during the movement of the cleaning device 100 driven by the driving wheel, the cleaning element 143 will not contact the surface to be cleaned, thereby avoiding the situation where the cleaning element 143 contacts the surface to be cleaned in scenarios where mopping is not required, causing secondary contamination of the surface to be cleaned, which is beneficial to improving the cleanliness of the cleaning device 100, improving cleaning efficiency and user experience.

[0061] In an embodiment of the present application, as shown in Figures 1, 3, 4, 7, 8, 9 and 12, a button assembly 150 and a voice collection component 190 are provided on the shell 110 of the cleaning device, and the voice collection component 190 is arranged around the button assembly 150; the button assembly 150 includes a movably arranged pressing portion 151, an opening 120 is provided on the shell 110, the pressing portion 151 is located at the opening 120, and the pressing portion 151 is provided with a limiting flange 160 extending to the bottom of the shell 110, and the limiting flange 160 is elastically connected to the shell 110.

[0062] When the user uses the cleaning device, the user can speak the corresponding voice instructions according to his or her needs, and then the voice acquisition component 190 obtains and recognizes the voice instructions, and then the control module controls the cleaning device to perform the corresponding task according to the voice instructions. For example, if the user wants to turn on the cleaning device, the user speaks the voice instruction of "turn on", and then the voice acquisition component 190 obtains and recognizes the power-on instruction, and then the control module turns on the cleaning device according to the power-on instruction; of course, the user can also press the part 151 to send the control signal of the corresponding operation to the controller, and the controller then controls the cleaning device to perform the corresponding task according to the control signal.

[0063] The pressing portion 151 is located at the opening 120 on the housing 110 and is movable, so that the user can press the pressing portion 151 to input the corresponding operation command. The pressing portion 151 can protrude from the upper surface of the housing 110 or be flush with the upper surface of the housing 110, thereby reducing the overall height of the cleaning device and thereby reducing the risk of the cleaning device getting stuck when cleaning low areas such as under a bed.

[0064] In one implementation, the pressing portion 151 can be set according to the number of operating instructions, that is, each operating instruction corresponds to a pressing portion 151. For example, the instruction for turning on and off the cleaning device corresponds to one pressing portion 151, and the instruction for selecting the cleaning mode (such as single sweep mode, single drag mode, or sweep first and then drag mode, etc.) corresponds to another pressing portion 151. In this way, the user presses the corresponding pressing portion 151 according to his or her needs to input the required operating instruction. In another implementation, as shown in Figure 1, the number of pressing portions 151 is one, and different operating instructions are corresponding to different areas on the pressing portion 151. For example, the front of the pressing portion 151 corresponds to the instruction for turning on and off the cleaning device, and the right side of the pressing portion 151 corresponds to the instruction for selecting the cleaning mode, etc. In this way, the user presses the corresponding area of ​​the pressing portion 151 according to his or her needs to input the required operating instruction. In this implementation, the pressing area of ​​the pressing portion 151 is large, so as to facilitate the user's pressing operation on different areas of the pressing portion 151 and improve the accuracy of the input instructions.

[0065] The limiting flange 160 is used to prevent the pressing portion 151 from escaping from the opening 120. The number of the limiting flanges 160 can be set by the staff according to the size of the pressing portion 151. In some embodiments, in order to improve the anti-escaping effect of the pressing portion 151, the number of the limiting flanges 160 is multiple and evenly distributed on the outer periphery of the pressing portion 151.

[0066] The limiting flange 160 is elastically connected to the shell 110, so when the pressing portion 151 is pressed by external force, the noise generated when the pressing portion 151 is pressed can be effectively reduced, thereby reducing the interference of the noise on the voice collection component 190, thereby improving the accuracy of voice recognition.

[0067] Specifically, in some embodiments, the limiting flange 160 includes a first elastic component made of soft rubber, which can reduce the collision sound generated by the limiting flange 160 and the housing 110 when the limiting flange 160 collides with the housing 110, thereby effectively reducing the noise generated when the pressing portion 151 is pressed, thereby reducing the interference of noise on the voice collection component 190 and improving the accuracy of voice recognition. Soft rubber is a soft and elastic material, generally composed of an elastomer, a plasticizer, a filler, and a plasticizer.

[0068] In other embodiments, as shown in Figures 3, 4, 7, 8, 9, and 12, a buffer member 170 is provided between the limiting flange 160 and the housing 110, thereby physically isolating the limiting flange 160 from the housing 110 and preventing direct collision between the limiting flange 160 and the housing 110. This provides a buffering and noise reduction function, effectively reducing the noise generated when the pressing portion 151 is pressed, thereby reducing the noise interference with the voice collection component 190 and improving the accuracy of voice recognition. In this embodiment, the limiting flange 160 can be made of a hard material (such as plastic), thereby improving the limiting flange 160's anti-oxidation and corrosion resistance, thereby increasing the service life of the limiting flange 160.

[0069] Specifically, as shown in Figures 3, 4, 7, 8, 9 and 12, the pressing part 151 includes a pressing plate 1511 and a pressing column 1512 for supporting the pressing plate 1511. The pressing column 1512 extends toward the interior of the shell 110. A second elastic component 152 made of soft rubber is provided below the pressing plate 1511. The second elastic component 152 is connected to the buffer component 170.

[0070] The shape of the pressing plate 1511 can be set by the staff, and this embodiment does not strictly limit it. In some embodiments, the pressing plate 1511 adopts a circular sheet structure to facilitate the installation of the pressing plate 1511; the opening 120 on the shell 110 is adapted to the pressing plate 1511.

[0071] The pressing column 1512 can be a cylindrical body or a cross-shaped body, which can save materials and ensure the pressing area of ​​the pressing column 1512 to improve the accuracy of input operation instructions.

[0072] The second elastic component 152 is located below the pressing plate 1511, so that the pressing plate 1511 is deformed when it is subjected to pressing force, thereby driving the pressing column 1512 to move downward through the downward pressing plate 1511 to generate downward force, thereby generating a corresponding electrical signal; and when the pressing force on the pressing plate 1511 disappears, the second elastic component 152 restores the deformation and generates a rebound force, so that the pressed part of the pressing plate 1511 returns to its original position, and also drives the pressing column 1512 to return to its original position, thereby completing the input of the operation instruction.

[0073] In specific applications, the pressing portion 151 and the pressing column 1512 can be assembled together using different assembly methods. In the first implementation method, as shown in Figures 3 and 8, the pressing portion 151 is connected to the pressing column 1512, so that the pressing portion 151 can better drive the pressing column 1512 to move, thereby improving the reliability of the pressing operation.

[0074] Furthermore, as shown in FIG3 , the pressing plate 1511 and the pressing column 1512 are integrally formed, thereby eliminating the need for a component step and improving work efficiency, and also increasing the reliability of the connection between the two and prolonging their service life.

[0075] In a second implementation, as shown in FIG8 , the pressing column 1512 passes through the second elastic component 152 and abuts against the pressing plate 1511 , thereby eliminating the assembly process and improving work efficiency.

[0076] In the above two implementations, as shown in FIG3 and FIG9 , the pressing plate 1511 and the limiting flange 160 are integrally formed, thereby eliminating the assembly process and improving work efficiency, and also increasing the reliability of the connection between the two and prolonging the service life. In the above embodiment, in which the pressing plate 1511 and the pressing post 1512 are integrally formed, the pressing plate 1511 is also integrally formed with the limiting flange 160. In other words, the pressing plate 1511, the pressing post 1512 and the limiting flange 160 are integrally formed, thereby eliminating the assembly process between the above components, further improving assembly efficiency, and also making the connection between the above components more reliable and extending the service life.

[0077] Furthermore, in some embodiments, the pressing plate 1511, the pressing post 1512, and the limiting flange 160 can be made of different materials. Specifically, the pressing plate 1511, the pressing post 1512, and the limiting flange 160 are all made of a hard material (such as plastic). Thus, the pressing plate 1511, the pressing post 1512, and the limiting flange 160 are integrally made of the hard material, while the second elastic portion and the buffer component 170 are integrally made of soft rubber. The second elastic component 152 and the pressing plate 1511 can be connected by bonding or other methods.

[0078] In other embodiments, the pressing plate 1511, the pressing column 1512 and the limiting flange 160 can be made of the same material. The pressing plate 1511, the pressing column 1512 and the limiting flange 160 are all made of soft rubber, so that when the pressing part 151 is pressed by external force, the noise generated when the pressing part 151 is pressed is smaller, thereby further reducing the interference of noise on the voice collection component 190, and thus the accuracy of voice recognition is higher.

[0079] Furthermore, the pressing plate 1511 , the pressing column 1512 , the limiting flange 160 and the second elastic component 152 are integrally formed, thereby further simplifying the assembly process, improving work efficiency, and further enhancing the reliability of the connection.

[0080] In the above embodiment, as shown in FIG3 , FIG4 and FIG9 , the second elastic component 152 is connected to the buffer component 170 , so that no additional fastening component is required to fix the buffer component 170 , thereby simplifying the structure and reducing costs.

[0081] Furthermore, as shown in Figures 3, 4 and 9, the buffer component 170 includes a third elastic component made of soft rubber, and the second elastic component 152 and the third elastic component are integrally formed, thereby eliminating the assembly process and improving the stability of the connection between the buffer component 170 and the second elastic component 152.

[0082] In some preferred embodiments, the pressing plate 1511, the pressing column 1512, the limiting flange 160, the second elastic component 152, and the buffer component 170 (i.e., the third elastic component) are integrally formed to form a whole, thereby making the connection between the above components more stable, eliminating the assembly process of the above components, making work efficiency higher, and also improving the overall sealing of the button assembly 150 to prevent dust and other dirt from entering the interior of the shell 110 through the gap between the pressing part 151 and the shell 110.

[0083] Furthermore, in specific applications, in order to facilitate the user to intuitively understand whether the operation instruction input through the button assembly 150 is successful, a prompt light is provided under each pressing column 1512. Therefore, when the user successfully inputs the operation instruction through the button assembly 150, the indicator light under the pressing column 1512 lights up to prompt the user that the operation instruction input is successful. In order to avoid mutual interference between the indicator lights, as shown in Figures 3 and 11, the part of the second elastic component 152 corresponding to each pressing column 1512 is provided with a hollow shading portion 1522, and each pressing column 1512 is located inside the corresponding shading portion 1522, so that the indicator light under the corresponding pressing column 1512 is blocked by each shading portion 1522 to avoid mutual interference between the indicator lights.

[0084] Furthermore, as shown in FIG11 , the shading portion 1522 is a columnar structure made of soft rubber, and the shading portion 1522 and the second elastic component 152 are integrally formed, thereby improving the shading property of the shading portion 1522 and eliminating the connection process between the shading portion 1522 and the second elastic component 152 .
