[0058] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. Like reference numerals in the figures denote the same or similar structures, and thus their detailed description will be omitted.

[0059] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of an icon to another component, these terms are used in this specification only for convenience, for example, according to the directions of the examples described in the drawings. It can be understood that if the device of the icon is turned upside down, the component described as "upper" will become the component described as "lower". When a structure is "on" another structure, it may mean that a structure is integrally formed on another structure, or that a structure is "directly" disposed on another structure, or that a structure is "indirectly" disposed on another structure through another structure.

[0060] The terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "comprising" and "having" are used to mean an open inclusion and mean that there may be additional elements / components / etc. in addition to the listed elements / components / etc.; the terms "first", "second", "third", etc. are used only as labels and are not a limitation on the quantity of their objects.

[0061] Embodiments of the present disclosure provide a cleaning device, which may be a floor sweeping robot, a mopping and sweeping integrated robot, a handheld floor sweeper, a handheld mopping and sweeping integrated machine, etc.; as Figure 1 and Figure 2 shown, hereinafter, the cleaning device 10 being a mopping and sweeping integrated robot is taken as an example for illustration. The cleaning device 10 may include a device body 11, a driving module 12, a sensing module 13, a control module 14, a cleaning module 15, an energy module 16, a human-machine interaction module 17, etc.

[0062] In some embodiments, the device body 11 is configured to automatically move along a target direction on a driving surface, and the driving surface may be the surface to be cleaned by the cleaning device 10. If the cleaning device 10 is a mopping and sweeping integrated robot, the cleaning device 10 works on the ground, and the ground is the above-mentioned operation surface.

[0063] To more clearly describe the behavior of the cleaning device 10, the following direction definitions are made: The cleaning device 10 can travel on the ground through various combinations of movements relative to the following three mutually perpendicular axes defined by the device body 11: the front-rear axis X, the lateral axis Y, and the central vertical axis Z. The forward driving direction along the front-rear axis X is marked as "forward", and the backward driving direction along the front-rear axis X is marked as "backward". The cleaning device 10 can rotate around the Y axis. When the forward part of the cleaning device 10 tilts upward and the backward part tilts downward, it is "pitching up", and when the forward part of the cleaning device 10 tilts downward and the backward part tilts upward, it is "pitching down". Additionally, the cleaning device 10 can rotate around the Z axis. In the forward direction of the cleaning device 10, when the cleaning device 10 tilts to the right side of the axis, it is "right turning", and when the cleaning device 10 tilts to the left side of the Y axis, it is "left turning".

[0064] In some embodiments, the drive module 12 includes a drive wheel assembly 121. The drive module 12 can control the left wheel and the right wheel simultaneously. To more precisely control the movement of the machine, it is preferred that the drive module 12 includes a left drive wheel assembly and a right drive wheel assembly respectively. The left and right drive wheel assemblies are symmetrically arranged along the lateral axis Y defined by the device body 11.

[0065] In some embodiments, as Figure 2 shown, in order to enable the automatic cleaning device 10 to move more stably on the ground or have stronger movement ability, the automatic cleaning device 10 can include one or more steering wheels 122; the steering wheels 122 can be driven wheels or driven wheels, and their structural forms include but are not limited to omnidirectional wheels. The steering wheels 122 can be located in front of the drive wheel assembly 121. The drive motor provides power for the drive wheel assembly 121 and / or the steering wheels 122.

[0066] In some embodiments, the sensing module 13 includes a position determination device located above the device body 11, a buffer located in the forward part of the device body 11, a cliff sensor, an ultrasonic sensor, an infrared sensor, a magnetometer, an accelerometer, a gyroscope, an odometer, and other sensing devices located at the bottom of the device body 11, and provides various position information and motion state information of the device body 11 to the control module 14. For example, a buffer is provided in the forward part of the device body 11. During the cleaning process, when the drive wheel assembly propels the cleaning device 10 to walk on the ground, the buffer detects one or more events (or objects) in the traveling path of the cleaning device 10 via a sensor module, such as an infrared sensor. The cleaning device 10 can control the drive structure to make the cleaning device 10 respond to the event (or object) detected by the buffer, such as a step, an obstacle, or a wall, for example, to cross a step.

[0067] In some embodiments, the control module 14 can comprehensively judge the current working state of the floor sweeper by combining the distance information and speed information fed back by sensing devices such as a buffer, a cliff sensor, an ultrasonic sensor, an infrared sensor, a magnetometer, an accelerometer, a gyroscope, and an odometer. For example, when climbing stairs, crossing a threshold, going onto a carpet, being at a cliff, being stuck above or below, having a full dustbin, being picked up, etc. It will also give specific next-action strategies for different situations, making the operation of the cleaning device 10 more in line with the requirements of the owner and providing a better user experience. Further, the control module 14 can plan the most efficient and reasonable cleaning path and cleaning method based on the instant map information drawn by SLAM (Simultaneous Localization and Mapping), which can improve the cleaning efficiency of the cleaning device 10.

[0068] In some embodiments, the energy module 16 includes a rechargeable battery, such as a nickel-metal hydride battery and a lithium battery. The rechargeable battery can be connected with a charging control circuit, a battery pack charging temperature detection circuit, and a battery under-voltage monitoring circuit, and the charging control circuit, the battery pack charging temperature detection circuit, and the battery under-voltage monitoring circuit are then connected to the single-chip microcomputer control circuit. The host is charged by connecting to a charging pile through charging electrodes arranged on the side or below the body.

[0069] In some embodiments, the human-computer interaction module 17 includes buttons on the host panel for users to select functions; it can also include a display screen and / or an indicator light and / or a speaker, and the display screen, the indicator light, and the speaker show the current state of the machine or function selection items to the user; it can also include a mobile phone client program. For a path-navigation type cleaning device, the mobile phone client can show the map of the environment where the device is located and the position of the machine to the user, and can provide more rich and user-friendly function items.

[0070] In some embodiments, the cleaning module 15 can include a dry cleaning module, or a dry and wet cleaning module. As Figure 2 shown, the dry cleaning module can include a roller brush assembly 151, a side brush 152, etc.; the wet cleaning module includes a cleaning head 153, a water tank, etc.

[0071] Currently, more and more cleaning devices 10 are equipped with functions such as lifting and obstacle crossing to improve the performance of the cleaning device 10 and thus enhance the market competitiveness. However, when the cleaning device 10 is lifting, crossing an obstacle, or encountering a bumpy road surface, the water in the water tank is likely to pour out from the water injection port of the cleaning device 10 due to shaking, especially when the water tank is just filled with water, and the phenomenon of pouring out from the water injection port is more serious. This phenomenon seriously affects the user experience and thus seriously affects the market competitiveness of the product.

[0072] Regarding this, in some embodiments, as Figures 3 to 10As shown, a water injection port 1151 is provided on the device body 11 of the cleaning device 10. A water tank is provided in the cleaning device 10, and the water tank is communicated with the water injection port 1151 through a pipeline. A receiving cavity 183 is provided on the pipeline communicating the water tank and the water injection port 1151; a one-way umbrella valve 181 is provided in the receiving cavity 183. The one-way umbrella valve 181 includes an elastically deformable sealing portion 1811, and the sealing portion 1811 is used to seal the water inlet 1831 of the receiving cavity 183.

[0073] Wherein, when the pressure received by the sealing portion 1811 from the water inlet 1831 is greater than the elastic deformation threshold of the sealing portion 1811, the sealing portion 1811 opens the water inlet 1831 after elastic deformation; when the pressure received by the sealing portion 1811 from the water inlet 1831 is less than the elastic deformation threshold of the sealing portion 1811, the sealing portion 1811 restores elastic deformation and seals the water inlet 1831.

[0074] By providing the one-way umbrella valve 181 on the pipeline between the water tank and the water injection port 1151, as Figure 9 shown, when injecting water into the water tank through the water injection port 1151, at this time, the pressure received by the sealing portion 1811 from the water inlet 1831 is greater than the elastic deformation threshold of the sealing portion 1811. The edge of the sealing portion 1811 of the one-way umbrella valve 181 turns outwards towards the direction of the water flow to open the water inlet 1831, so that the pipeline between the water injection port 1151 and the water tank is conducted. At this time, the water from the water injection port 1151 can be injected into the water tank through the water inlet 1831; as Figure 10 shown, when stopping injecting water into the water tank, that is, when the pressure received by the sealing portion 1811 from the water inlet 1831 is less than the elastic deformation threshold of the sealing portion 1811, at this time, the edge of the sealing portion 1811 of the one-way umbrella valve 181 will not turn outwards and deform, and is in a state of sealing the water inlet 1831; when the cleaning device 10 is lifting, crossing an obstacle or encountering a bumpy road surface, the one-way umbrella valve 181 cuts off the pipeline between the water tank and the water injection port 1151. Therefore, the water in the water tank will not flow back out through the water injection port 1151, improving the user experience and thus being able to enhance the market competitiveness of the product.

[0075] In some embodiments, as Figure 3 and Figure 4 shown, a water injection nozzle 115 is provided on the device body 11, and a water injection port 1151 is formed on the water injection nozzle 115. By providing the water injection nozzle 115, it is convenient to match and connect the water injection port 1151 with an external water injection device, avoiding water leakage when injecting water through the water injection port 1151.

[0076] In some embodiments, the device body 11 includes a top surface, a bottom surface and a side surface located between the top surface and the bottom surface, and the water injection port 1151 is located on the side surface of the device body 11.

[0077] Specifically, asFigure 2 and Figure 3 As shown in Figure 3 , the main body housing includes an upper shell 111, a bottom shell 112, and a middle shell 113 located between the upper shell 111 and the bottom shell 112. The water inlet 1831 is located on the middle shell 113, that is, the water injection nozzle 115 is assembled on the middle shell 113, or the water injection nozzle 115 is directly formed on the middle shell 113.

[0078] Among them, as Figures 3 to 6 shown in Figures 3 to 6 , an installation plate 114 can also be provided on the middle shell 113. The water injection nozzle 115 is assembled on the installation plate 114, or the water injection nozzle 115 is directly formed on the installation plate 114. By providing the installation plate 114, the modularization of the device is further realized, facilitating the assembly and maintenance of each functional component in the cleaning device 10.

[0079] In some embodiments, as Figures 7 to 10 shown in Figures 7 to 10 , the cleaning device 10 includes: a one-way valve assembly 18. The one-way valve assembly 18 includes a one-way valve housing 182 and the above-mentioned one-way umbrella valve 181. The one-way valve housing 182 is formed with a receiving cavity 183, a water inlet 1831 and a water outlet 1832 communicating with the receiving cavity 183. The water inlet 1831 is communicated with the water injection port 1151, and the water outlet 1832 is communicated with the water tank. By providing the one-way valve housing 182 to form the receiving cavity 183, it is convenient to arrange the one-way umbrella valve 181, making the sealing and conducting functions of the one-way umbrella valve 181 between the water injection port 1151 and the pipeline of the water tank more stable.

[0080] In some embodiments, as Figures 7 to 10 shown in Figures 7 to 10 , the one-way valve housing 182 includes a first housing 1821 and a second housing 1822. The first housing 1821 and the second housing 1822 are hermetically connected to form the receiving cavity 183; the water inlet 1831 is provided on the first housing 1821, and the water outlet 1832 is provided on the second housing 1822.

[0081] By providing the first housing 1821 and the second housing 1822 to be hermetically connected to form the receiving cavity 183, it is convenient to arrange a one-way valve in the receiving cavity 183; as Figure 9 shown in Figure 9 , when injecting water into the water tank through the water injection port 1151, when the pressure received by the sealing portion 1811 from the water inlet 1831 is greater than the elastic deformation threshold of the sealing portion 1811, the edge of the sealing portion 1811 of the one-way umbrella valve 181 turns outwards towards the direction of the water flow and separates from the inner wall of the first housing 1821 to conduct the water inlet 1831 and the receiving cavity 183; as Figure 10As shown, when the water injection into the water tank through the water injection port 1151 stops, that is, the pressure on the sealing part 1811 from the water inlet 1831 is less than the elastic deformation threshold of the sealing part 1811. At this time, the edge of the sealing part 1811 of the one-way umbrella valve 181 is in close contact with the inner wall of the first housing 1821 to seal the water inlet 1831 and cut off the connection between the water inlet 1831 and the accommodation cavity 183.

[0082] In some embodiments, the second housing 1822 is hermetically connected to the device body 11 to make the water inlet 1831 and the water injection port 1151 in sealed communication. The accommodation cavity 183 is formed by the hermetic connection between the first housing 1821 and the second housing 1822. At this time, the water inlet 1831 on the first housing 1821 and the water injection port 1151 need to be in sealed communication. By hermetically connecting the second housing 1822 and the device body 11, the sealed communication between the water inlet 1831 and the water injection port 1151 is achieved.

[0083] In some embodiments, as Figures 6 to 10 shown, the one-way valve housing 182 is hermetically connected to the water injection nozzle 115 to form the accommodation cavity 183. By hermetically connecting the second housing 1822 and the water injection nozzle 115, the sealed communication between the water inlet 1831 and the water injection port 1151 is achieved, and thus the fixation of the one-way valve assembly 18 is realized.

[0084] Among them, the second housing 1822 and the water injection nozzle 115 can be hermetically connected by means of threaded connection, bonding, welding, snap connection, etc.

[0085] Among them, a sealing ring can be arranged between the sealing connection surfaces of the second housing 1822 and the water injection nozzle 115. By arranging the sealing ring, the sealing performance of the sealing connection surfaces of the second housing 1822 and the water injection nozzle 115 is improved.

[0086] Among them, a guiding structure can be arranged between the second housing 1822 and the water injection nozzle 115. By arranging the guiding structure, the positioning and assembly between the second housing 1822 and the water injection nozzle 115 are formed, so as to improve the accuracy of the connection position between the second housing 1822 and the water injection nozzle 115, avoid misaligned connection, and further improve the sealing performance of the sealing connection surface.

[0087] Among them, an anti-misassembly structure can be arranged between the second housing 1822 and the water injection nozzle 115. By arranging the anti-misassembly structure, the assembly efficiency can be improved and installation errors can be avoided. For example, two mounting posts with different diameters and / or shapes are arranged on the water injection nozzle 115, and two mounting holes matching the mounting posts are arranged on the second housing 1822. Different mounting posts are matched and installed with the corresponding mounting holes, thus avoiding the misalignment of the installation of the second housing 1822.

[0088] In some embodiments, the one-way valve housing 182 is sealingly connected to the main housing to form a receiving cavity 183. When the water injection port 1151 is directly formed through the main housing, after the second housing 1822 and the first housing 1821 are connected to form the receiving cavity 183, the second housing 1822 can be directly sealingly connected to the main housing to achieve sealing communication between the water inlet 1831 and the water injection port 1151. Among them, the sealing connection method and positioning method between the second housing 1822 and the main housing can be the same as the sealing connection method and positioning method between the second housing 1822 and the water injection nozzle 115 described above, and will not be elaborated here.

[0089] Among them, the one-way valve housing 182 can be sealingly connected to the mounting plate 114 or the middle housing 113 to form a receiving cavity 183.

[0090] In some embodiments, the one-way valve housing 182 and the device body 11 cooperate to form a receiving cavity 183, the water injection port 1151 communicates with the receiving cavity 183 to serve as the water inlet 1831 of the receiving cavity 183, and a water outlet 1832 communicating with the receiving cavity 183 is provided on the one-way valve housing 182, and the water outlet 1832 communicates with the water tank; that is, the second housing 1822 and the device body 11 cooperate to form a receiving cavity 183, and the water injection port 1151 communicates with the receiving cavity 183 to serve as the water inlet 1831 of the receiving cavity 183. Among them, after the second housing 1822 and the device body 11 cooperate to form the receiving cavity 183, the water injection port 1151 is the water inlet 1831, and the sealing portion 1811 of the one-way umbrella valve 181 can be sealingly connected to the device body 11 at the water injection port 1151 to cut off the pipeline between the water tank and the water injection port 1151.

[0091] Among them, when the water injection nozzle 115 is provided on the device body 11, the second housing 1822 directly cooperates with the water injection nozzle 115 to form a receiving cavity 183; when the water injection port 1151 is directly formed on the middle housing 113, the second housing 1822 directly cooperates with the middle housing 113 to form a receiving cavity 183; when a mounting plate 114 is provided on the middle housing 113 and the water injection port 1151 is directly formed on the mounting plate 114, the second housing 1822 directly cooperates with the mounting plate 114 to form a receiving cavity 183. Among them, the sealing connection method and positioning method of the second housing 1822 directly cooperating with the water injection nozzle 115, the middle housing 113 or the mounting plate 114 to form the receiving cavity 183 can be the same as the sealing connection method and positioning method of the second housing 1822 and the water injection nozzle 115 in the above embodiments, and will not be elaborated here.

[0092] In some embodiments, as Figures 9 to 13 shown, the one-way umbrella valve 181 further includes a rod portion 1812. A limiting structure is formed inside the one-way valve housing 182, and the end of the rod portion 1812 is located in the limiting structure, and the limiting structure forms axial and radial limits on the rod portion 1812.

[0093] Specifically, the one-way umbrella valve 181 includes a rod portion 1812 and a sealing portion 1811. The sealing portion 1811 extends radially toward the rod portion 1812 in a shape of an umbrella surface; the sealing portion 1811 has good elastic properties. As Figure 11 and Figure 12 shown, when the pressure received by the sealing portion 1811 from the water inlet 1831 is less than the elastic deformation threshold of the sealing portion 1811 or the sealing portion 1811 does not receive the water pressure from the water injection port 1151, the edge of the sealing portion 1811 of the one-way umbrella valve 181 does not turn outwards; as Figure 13 shown, when the pressure received by the sealing portion 1811 from the water inlet 1831 is greater than the elastic deformation threshold of the sealing portion 1811, the edge of the sealing portion 1811 of the one-way umbrella valve 181 turns outwards towards the direction of the water flow.

[0094] Among them, the one-way umbrella valve 181 can be a rubber part, and the hardness of the rod portion 1812 is greater than that of the sealing portion 1811, so as to improve the stability of the one-way umbrella valve 181 after assembly; at the same time, since the one-way umbrella valve 181 is in contact with water for a long time, the service life and performance of the one-way umbrella valve 181 can be improved through the rubber part.

[0095] Among them, the elastic deformation threshold can be set by adjusting the elastic modulus of the rubber material of the sealing portion 1811 or adjusting the thickness of the sealing portion 1811, etc.; the elastic deformation threshold only needs to satisfy that the edge of the sealing portion 1811 turns outwards and opens during water injection, and the edge of the sealing portion 1811 does not turn outwards and remains in its original shape when not injecting water. The present disclosure does not limit this.

[0096] In some embodiments, as Figure 14 shown, the limiting structure includes a plurality of limiting protrusions 184 connected to the inner wall of the one-way valve housing 182, and the plurality of limiting protrusions 184 are arranged at intervals. By providing the limiting protrusions 184, axial and radial limits are formed on the rod portion 1812 of the one-way umbrella valve 181. On the one hand, the installation accuracy of the one-way umbrella valve 181 is improved, and the stability of the one-way umbrella valve 181 after being assembled in the accommodation cavity 183 is improved; on the other hand, the space between the plurality of limiting protrusions 184 can be used as a flow channel, avoiding the influence of the setting of the plurality of limiting protrusions 184 on the fluidity during water injection.

[0097] Among them, the second housing 1822 is disposed opposite to the water inlet 1831, that is, the limiting structure is formed on the second housing 1822, that is, the plurality of limiting protrusions 184 are formed on the second housing 1822.

[0098] Among them, as Figure 14As shown, the water outlet 1832 is located on the one-way valve housing 182 between two adjacent limiting protrusions 184. By positioning the water outlet 1832 on the one-way valve housing 182 between two adjacent limiting protrusions 184, the limiting protrusions 184 are prevented from blocking the water outlet 1832, enhancing the fluidity during water injection.

[0099] In some embodiments, as Figure 14 shown, the one-way valve housing 182 includes a top wall 18221 opposite to the end face of the rod portion 1812 and a side wall 18222 opposite to the outer peripheral surface of the rod portion 1812. The limiting structure is connected to the top wall 18221 and is spaced from the side wall 18222, that is, the limiting structure is connected to the top wall 18221 of the second housing 1822. By connecting the limiting structure to the top wall 18221 of the second housing 1822, the space between the limiting structure and the side wall 18222 can serve as a flow channel, preventing the arrangement of multiple limiting protrusions 184 from affecting the fluidity during water injection. Of course, the limiting structure can also be connected to both the top wall 18221 and the side wall 18222 of the second housing 1822, and the present disclosure does not limit this.

[0100] Among them, as Figure 14 shown, the limiting protrusion 184 includes a connecting portion 1841. One end of the connecting portion 1841 is connected to the top wall 18221, and a limiting groove 1842 is provided at the other end; the limiting grooves 1842 of multiple limiting protrusions 184 face each other, forming a mounting groove for the rod portion 1812 on the one-way valve housing 182. The mounting groove simultaneously forms axial and radial limitations on the rod portion 1812. For example, by providing four limiting protrusions 184, the openings of the limiting grooves 1842 on the four limiting protrusions 184 face each other in pairs to form a mounting groove. Of course, three, five, or more limiting protrusions 184 can also be provided, and the present disclosure does not limit this.

[0101] In some embodiments, in the axial direction of the rod portion 1812, the length of the one-way umbrella valve 181 in the free state is greater than the distance between the contact position of the limiting structure and the end face of the rod portion 1812 and the water inlet 1831, that is, greater than the distance between the contact position of the limiting protrusion 184 and the end face of the rod portion 1812 and the water inlet 1831. By making the length of the one-way umbrella valve 181 in the free state greater than the distance between the contact position of the limiting protrusion 184 and the end face of the rod portion 1812 and the water inlet 1831, that is, after the one-way umbrella valve 181 is assembled in the accommodating cavity 183, the one-way umbrella valve 181 is subjected to the extrusion force generated by the cooperation of the limiting protrusion 184 and the first housing 1821, so that there is a pre-tightening force between the contact surface of the one-way umbrella valve 181 and the first housing 1821, making the sealing portion 1811 of the one-way umbrella valve 181 in close contact with the inner wall of the second housing 1822, thereby enhancing the sealing performance of the one-way umbrella valve 181 for the water inlet 1831.

[0102] In some embodiments, as Figure 15 shown, a nozzle 185 is provided on the check valve housing 182, that is, a nozzle 185 is provided on the second housing 1822. The nozzle 185 communicates with the accommodation cavity 183 through the water outlet 1832, and the nozzle 185 communicates with the water tank through a conduit. By providing the nozzle 185 on the second housing 1822, the convenience and sealing performance of the connection between the water outlet 1832 of the accommodation cavity 183 and the conduit are improved.

[0103] In some embodiments, the second housing 1822, the limiting protrusion 184 and the nozzle 185 can be an integrally formed structure. On the one hand, it can improve the structural strength of the check valve assembly 18, and on the other hand, it can improve the sealing performance of the check valve assembly 18. In other embodiments, any two of the second housing 1822, the limiting protrusion 184 and the nozzle 185 can be an integrally formed structure, and the remaining one can be a split structure connected together by means such as bonding, welding, and clamping; or, the second housing 1822, the limiting protrusion 184 and the nozzle 185 are all split structures connected together by means such as bonding, welding, and clamping.

[0104] The embodiments of the present disclosure also provide a cleaning system, as Figure 16 shown, the cleaning system includes a base station 20 and the cleaning device 10 provided in the above embodiments. The base station 20 is used to park the cleaning device 10, and the cleaning device 10 can perform functions such as charging, self-cleaning, docking, sewage discharge, and water replenishment on the base station 20.
