[0051] Embodiments of the present disclosure provide a cleaning device, which can be a robot vacuum cleaner, a robot mop, a handheld robot vacuum cleaner, a handheld robot mop, or the like. As shown in FIGS. 1 and 2, the present disclosure will be exemplarily described below by taking a robot mop as an example, which can 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-computer interaction module 17, and the like.

[0052] In some embodiments, the device body 11 is configured to automatically move along a target direction on a travel surface, which can be a surface to be cleaned by the cleaning device 10. The cleaning device 10 can be a robot mop, and the cleaning device 10 works on a ground, which is the above-mentioned travel surface.

[0053] In order to more clearly describe the behavior of the cleaning device 10, the following definitions are made: the cleaning device 10 can travel on the ground by various combinations of movements relative to the following three mutually perpendicular axes defined by the device body 11: a front-rear axis X, a lateral axis Y, and a central vertical axis Z. The forward driving direction along the front-rear axis X is denoted as “forward”, and the backward driving direction along the front-rear axis X is denoted as “backward”. The cleaning device 10 can rotate about the Y axis. When the forward part of the cleaning device 10 is tilted upward and the backward part is tilted downward, it is “pitched up”, and when the forward part of the cleaning device 10 is tilted downward and the backward part is tilted upward, it is “pitched down”.

The left and right driving wheel assemblies are symmetrically arranged along the lateral axis Y defined by the device body 11.

[0055] In some embodiments, as shown in FIG. 2, in order to enable the automatic cleaning device 10 to move more stably on the ground or have stronger movement capability, the automatic cleaning device 10 can include one or more steering wheels 122; the steering wheel 122 can be a driven wheel or a driving wheel, and its structural form includes but is not limited to a universal wheel. The steering wheel 122 can be located in front of the driving wheel assembly 121. A driving motor provides power for the driving wheel assembly 121 and / or the steering wheel 122.

[0056] In some embodiments, the perception module 13 includes a position determining device located above the device body 11, a bumper located at the front part of the device body 11, a cliff sensor and an ultrasonic sensor located at the bottom of the device body 11, an infrared sensor, a magnetometer, an accelerometer, a gyroscope, an odometer, and the like, which provide various position information and motion state information of the device body 11 to the control module 14. For example, the front part of the device body 11 is provided with a bumper, when the driving wheel assembly propels the cleaning device 10 to walk on the ground during the cleaning process, the bumper detects one or more events (or objects) in the travel path of the cleaning device 10 via a sensor module, such as an infrared sensor, and the cleaning device 10 can control the driving structure to respond to the event (or object) by detecting the event (or object) by the bumper, such as a step, an obstacle, a wall, and the like.

[0057] In some embodiments, the control module 14 can comprehensively judge the current working state of the robot vacuum cleaner, such as climbing a step, passing a threshold, being on a carpet, being stuck above or below, being full of dust, being picked up, and the like, based on the distance information and speed information fed back by the bumper, the cliff sensor and the ultrasonic sensor, the infrared sensor, the magnetometer, the accelerometer, the gyroscope, the odometer, and the like, and can give specific next action strategies for different situations, so that the work of the cleaning device 10 is more in line with the requirements of the owner and has better user experience. Further, the control module 14 can plan the most efficient and reasonable cleaning path and cleaning method based on the real-time map information drawn by SLAM (Simultaneous Localization and Mapping), which can improve the cleaning efficiency of the cleaning device 10.

[0058] In some embodiments, the energy module 16 includes a rechargeable battery, such as a nickel-hydrogen 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 undervoltage monitoring circuit, and the charging control circuit, the battery pack charging temperature detection circuit, and the battery undervoltage monitoring circuit are connected with a single-chip microcomputer control circuit.

For path navigation type cleaning devices, the mobile phone client can show the user a map of the environment where the device is located, and the position of the machine, and can provide more rich and personalized function items to the user.

[0060] In some embodiments, the cleaning module 15 can include a dry cleaning module, or a dry and wet cleaning module. As shown in FIG. 2, the dry cleaning module can include a roller brush assembly 151, an edge brush 152, etc.; the wet cleaning module includes a cleaning head 153, a water tank, etc.

[0061] At present, more and more cleaning devices 10 have the functions of lifting and obstacle crossing, so as to improve the use performance of the cleaning device 10, and thus improve the market competitiveness. However, when the cleaning device 10 is lifting, crossing obstacles or encountering a bumpy road, the water in the water tank is easy to flow back from the water inlet of the cleaning device 10 through shaking, especially when the water tank is just filled with water, the phenomenon of flowing back from the water inlet is more serious, which seriously affects the user's use experience, and thus seriously affects the market competitiveness of the product.

[0062] To this end, in some embodiments, as shown in FIGS. 3-10, the device body 11 of the cleaning device 10 is provided with a water inlet 1151, the cleaning device 10 is provided with a water tank, the water tank is in communication with the water inlet 1151 through a pipeline, and a containing cavity 183 is arranged on the pipeline in communication between the water tank and the water inlet 1151; a one-way umbrella valve 181 is arranged in the containing cavity 183, and the one-way umbrella valve 181 includes an elastically deformable sealing portion 1811, which is used to seal a water inlet 1831 of the containing cavity 183.

[0063] When the sealing portion 1811 is subjected to a pressure from the water inlet 1831 greater than the elastic deformation threshold of the sealing portion 1811, the sealing portion 1811 opens the water inlet 1831 by elastic deformation; when the sealing portion 1811 is subjected to a pressure from the water inlet 1831 less than the elastic deformation threshold of the sealing portion 1811, the sealing portion 1811 seals the water inlet 1831 after restoring the elastic deformation.

[0064] When water is injected into the water tank through the water injection port 1151, the sealing portion 1811 is subjected to a pressure from the water inlet 1831 that 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 is turned outward toward 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, and water from the water injection port 1151 can be injected into the water tank through the water inlet 1831; when water injection is stopped, that is, the sealing portion 1811 is subjected to a pressure from the water inlet 1831 that is less than the elastic deformation threshold of the sealing portion 1811, the edge of the sealing portion 1811 of the one-way umbrella valve 181 does not turn outward and deform, and the water inlet 1831 is in a sealed state; when the cleaning device 10 is ascending, climbing obstacles, or encountering bumpy roads, the one-way umbrella valve 181 blocks the pipeline between the water tank and the water injection port 1151, so that the water in the water tank cannot flow out through the water injection port 1151, improving the user experience and the market competitiveness of the product.

[0065] In some embodiments, as shown in FIGS. 3 and 4, the device body 11 is provided with a water injection nozzle 115, and the water injection nozzle 115 is formed with a water injection port 1151. The water injection nozzle 115 is arranged to facilitate the matching connection of the water injection port 1151 with external water injection equipment, avoiding water leakage when water is injected through the water injection port 1151.

[0066] In some embodiments, the device body 11 includes a top surface, a bottom surface, and a side surface 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.

[0067] Specifically, as shown in FIGS. 2 and 3, the main body shell includes an upper shell 111, a bottom shell 112, and a middle shell 113 between the upper shell 111 and the bottom shell 112, and 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.

[0068] As shown in FIGS. 3 to 6, the middle shell 113 can further be provided with a mounting plate 114, and the water injection nozzle 115 is assembled on the mounting plate 114, or the water injection nozzle 115 is directly formed on the mounting plate 114. The mounting plate 114 is arranged to further realize the modularity of the device, facilitating the assembly and maintenance of various functional devices in the cleaning device 10.

[0069] In some embodiments, as shown in FIGS. 7-10, the cleaning device 10 comprises a one-way valve assembly 18, which comprises 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 containing cavity 183 and a water inlet 1831 and a water outlet 1832 communicating with the containing cavity 183, the water inlet 1831 communicates with the water injection port 1151, and the water outlet 1832 communicates with the water tank. By providing the one-way valve housing 182 to form the containing cavity 183, the one-way umbrella valve 181 is provided, so that the sealing and conduction of the one-way umbrella valve 181 in the pipeline between the water injection port 1151 and the water tank are more stable.

[0070] In some embodiments, as shown in FIGS. 7-10, the one-way valve housing 182 comprises a first housing 1821 and a second housing 1822, the first housing 1821 and the second housing 1822 sealingly connect the containing 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.

[0071] By providing the first housing 1821 and the second housing 1822 to sealingly connect and form the containing cavity 183, the one-way valve is facilitated to be arranged in the containing cavity 183; as shown in FIG. 9, when water is injected into the water tank through the water injection port 1151, at this time, if the pressure of the sealing part 1811 from the water inlet 1831 is greater than the elastic deformation threshold of the sealing part 1811, the edge of the sealing part 1811 of the one-way umbrella valve 181 is turned outward to the direction of the water flow and separated from the inner wall of the first housing 1821 to conduct the water inlet 1831 and the containing cavity 183; as shown in FIG. 10, when the injection of water into the water tank through the water injection port 1151 is stopped, that is, if the pressure of 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 water inlet 1831 and the containing cavity 183.

[0072] In some embodiments, the second housing 1822 is sealingly connected with the device body 11 to sealingly conduct the water inlet 1831 and the water injection port 1151. By sealingly connecting the first housing 1821 and the second housing 1822 to form the containing cavity 183, the water inlet 1831 on the first housing 1821 and the water injection port 1151 need to be sealingly conducted, and by sealingly connecting the second housing 1822 with the device body 11, the water inlet 1831 and the water injection port 1151 are sealingly conducted.

[0073] In some embodiments, as shown in FIGS. 6-10, the one-way valve housing 182 is sealingly connected with the water injection nozzle 115 to form the containing cavity 183. The water inlet 1831 is sealingly communicated with the water injection nozzle 115 by sealingly connecting the second housing 1822 with the water injection nozzle 115, thereby achieving the fixation of the one-way valve assembly 18.

[0074] The second housing 1822 and the water injection nozzle 115 can be sealingly connected by threads, adhesion, welding, clamping, or the like.

[0075] A sealing ring can be arranged between the sealing connection surface of the second housing 1822 and the water injection nozzle 115 to improve the sealing performance of the sealing connection surface.

[0076] A guide structure can be arranged between the second housing 1822 and the water injection nozzle 115. The guide structure can be used to position and assemble the second housing 1822 and the water injection nozzle 115, thereby improving the positioning accuracy of the connection between the second housing 1822 and the water injection nozzle 115, avoiding mispositioning, and improving the sealing performance of the sealing connection surface.

[0077] A foolproof structure can be arranged between the second housing 1822 and the water injection nozzle 115. The foolproof structure can improve the assembly efficiency and avoid installation errors. For example, two installation posts with different diameters and / or shapes can be arranged on the water injection nozzle 115, and two installation holes matching the installation posts can be arranged on the second housing 1822. The different installation posts are matched with the corresponding installation holes, thereby avoiding mispositioning of the second housing 1822.

[0078] In some embodiments, the one-way valve housing 182 is sealingly connected with the main body housing to form the containing cavity 183. When the water injection nozzle 115 is directly formed through the main body housing, the second housing 1822 is sealingly connected with the first housing 1821 to form the containing cavity 183, and then the second housing 1822 is sealingly connected with the main body housing to achieve the sealing communication between the water inlet 1831 and the water injection nozzle 115. The sealing connection mode and the positioning mode of the second housing 1822 and the main body housing can be the same as those of the second housing 1822 and the water injection nozzle 115, which will not be described herein.

[0079] The one-way valve housing 182 can be sealingly connected with the mounting plate 114 or the middle housing 113 to form the containing cavity 183.

Wherein, after the second housing 1822 cooperates with the device body 11 to form the containing cavity 183, the water injection port 1151 becomes the water inlet 1831, and the sealing part 1811 of the one-way umbrella valve 181 can be sealingly connected with the device body 11 at the water injection port 1151 to block the pipeline between the water tank and the water injection port 1151.

[0081] Wherein, when the device body 11 is provided with the water injection nozzle 115, the second housing 1822 directly cooperates with the water injection nozzle 115 to form the containing cavity 183; when the water injection port 1151 is directly formed on the middle shell 113, the second housing 1822 directly cooperates with the middle shell 113 to form the containing cavity 183; when the middle shell 113 is provided with the mounting plate 114, 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 the containing cavity 183. Wherein, the sealing connection mode and the positioning mode of the second housing 1822 directly cooperating with the water injection nozzle 115, the middle shell 113 or the mounting plate 114 to form the containing cavity 183 can be the same as the sealing connection mode and the positioning mode of the second housing 1822 directly cooperating with the water injection nozzle 115 in the above-mentioned embodiments, which will not be described here.

[0082] In some embodiments, as shown in FIGS. 9-13, the one-way umbrella valve 181 further includes a rod part 1812, and a limiting structure is formed in the one-way valve housing 182, and the end of the rod part 1812 is located in the limiting structure to limit the axial and radial directions of the rod part 1812.

[0083] Specifically, the one-way umbrella valve 181 includes the rod part 1812 and the sealing part 1811, and the sealing part 1811 extends radially towards the rod part 1812 to form an umbrella shape; the sealing part 1811 has good elastic properties. As shown in FIGS. 11 and 12, when the pressure of the sealing part 1811 from the water inlet 1831 is less than the elastic deformation threshold of the sealing part 1811 or the sealing part 1811 is not subjected to water pressure from the water injection port 1151, the edge of the sealing part 1811 of the one-way umbrella valve 181 does not turn outwards; as shown in FIG. 13, when the pressure of the sealing part 1811 from the water inlet 1831 is greater than the elastic deformation threshold of the sealing part 1811, the edge of the sealing part 1811 of the one-way umbrella valve 181 turns outwards towards the direction of the water flow.

[0084] The one-way umbrella valve 181 can be a rubber part, and the hardness of the rod portion 1812 is greater than the hardness 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 use performance of the one-way umbrella valve 181 can be improved through the rubber part.

[0085] The elastic modulus of the rubber material of the sealing portion 1811 or the thickness of the sealing portion 1811 can be adjusted to set the elastic deformation threshold. The elastic deformation threshold satisfies that the edge of the sealing portion 1811 is turned out to open when water injection, and the edge of the sealing portion 1811 is not turned out to keep the original shape when no water injection. The present disclosure does not limit this.

[0086] In some embodiments, as shown in FIG. 14, the limiting structure includes a plurality of limiting protrusions 184 connected to the inner wall of the one-way valve shell 182, and the plurality of limiting protrusions 184 are arranged at intervals. By arranging the limiting protrusions 184, the rod portion 1812 of the one-way umbrella valve 181 is limited in the axial and radial directions, which improves the installation precision of the one-way umbrella valve 181 and improves the stability of the one-way umbrella valve 181 after assembly in the accommodating cavity 183. On the other hand, the space between the plurality of limiting protrusions 184 can be used as a flow channel, so that the flowability during water injection is not affected by the arrangement of the plurality of limiting protrusions 184.

[0087] The second shell 1822 is arranged opposite to the water inlet 1831, that is, the limiting structure is formed on the second shell 1822, that is, the plurality of limiting protrusions 184 are formed on the second shell 1822.

[0088] As shown in FIG. 14, the water outlet 1832 is located on the one-way valve shell 182 between the adjacent two limiting protrusions 184. By arranging the water outlet 1832 on the one-way valve shell 182 between the adjacent two limiting protrusions 184, the limiting protrusions 184 do not block the water outlet 1832, and the flowability during water injection is improved.

[0089] In some embodiments, as shown in FIG. 14, the one-way valve shell 182 includes a top wall 18221 opposite to the end surface of the rod portion 1812 and a side wall 18222 opposite to the outer peripheral surface of the rod portion 1812, and the limiting structure is connected to the top wall 18221 and arranged at intervals from the side wall 18222, that is, the limiting structure is connected to the top wall 18221 of the second shell 1822. By arranging the limiting structure on the top wall 18221 of the second shell 1822, the space between the limiting structure and the side wall 18222 can be used as a flow channel, so that the flowability during water injection is not affected by the arrangement of the plurality of limiting protrusions 184. Of course, the limiting structure can be connected to the top wall 18221 and the side wall 18222 of the second shell 1822 at the same time, and the present disclosure does not limit this.

[0090] Wherein, as shown in FIG. 14, the limiting protrusion 184 comprises a connecting portion 1841, one end of the connecting portion 1841 is connected with the top wall 18221, and the other end is provided with a limiting groove 1842; the limiting grooves 1842 of the plurality of limiting protrusions 184 are oppositely arranged to form an installation groove of the upper rod portion 1812 of the one-way valve shell 182, and the installation groove simultaneously forms the limiting of the upper rod portion 1812 in the axial and radial directions. For example, by arranging four limiting protrusions 184, the openings of the limiting grooves 1842 on the four limiting protrusions 184 are oppositely arranged to form the installation groove. Of course, three, five or more limiting protrusions 184 can also be arranged, and the present disclosure does not limit this.

[0091] 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 abutting 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 abutting 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 abutting 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 shell 1821, so that the one-way umbrella valve 181 has a pre-tightening force between the contact surface of the one-way umbrella valve 181 and the first shell 1821, so that the sealing portion 1811 of the one-way umbrella valve 181 is in close contact with the inner wall of the second shell 1822, thereby improving the sealing performance of the one-way umbrella valve 181 to the water inlet 1831.

[0092] In some embodiments, as shown in FIG. 15, the one-way valve shell 182 is provided with a connector 185, that is, the second shell 1822 is provided with a connector 185, the connector 185 is communicated with the accommodating cavity 183 through the water outlet 1832, and the connector 185 is communicated with the water tank through a conduit. By arranging the connector 185 on the second shell 1822, the convenience and sealing performance of the connection between the water outlet 1832 of the accommodating cavity 183 and the conduit are improved.

[0093] In some embodiments, the second shell 1822, the limiting protrusion 184 and the connector 185 can be an integral molding structure, which can improve the structural strength and sealing performance of the one-way valve assembly 18. In other embodiments, any two of the second shell 1822, the limiting protrusion 184 and the connector 185 can be an integral molding structure, and the remaining one can be a split structure connected by bonding, welding, clamping or the like; or, the second shell 1822, the limiting protrusion 184 and the connector 185 are all split structures connected by bonding, welding, clamping or the like.

[0094] The cleaning device provided by the present disclosure is provided with a one-way umbrella valve on the pipeline between the water tank and the water inlet; when water is injected into the water tank through the water inlet, the sealing part is subjected to a pressure from the water inlet that is greater than the elastic deformation threshold of the sealing part, the sealing part edge of the one-way umbrella valve is turned outward toward the direction of the water flow to open the water inlet, so that the pipeline between the water inlet and the water tank is connected, and at this time, water from the water inlet can be injected into the water tank through the water inlet; when water injection is stopped, that is, the sealing part is subjected to a pressure from the water inlet that is less than the elastic deformation threshold of the sealing part, at this time, the sealing part edge of the one-way umbrella valve will not be deformed outward, and the sealing part is in a state of sealing the water inlet; when the cleaning device is ascending, climbing obstacles or encountering bumpy roads, the one-way umbrella valve will cut off the pipeline between the water tank and the water inlet, so that the water in the water tank will not flow out through the water inlet, thereby improving the user experience, and further improving the market competitiveness of the product.

[0095] The embodiment of the present disclosure also provides a cleaning system, as shown in FIG. 16, which comprises a base station 20 and the cleaning device 10 provided by the above-mentioned embodiment, and the base station 20 is used for parking the cleaning device 10, and the cleaning device 10 can perform functions such as charging, self-cleaning, parking, sewage discharge, water replenishment and the like on the base station 20.
