Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a cleaning base station and a cleaning system. Background Art

[0002] Cleaning robots, such as sweeping robots and smart vacuums, are a type of smart appliance that leverages artificial intelligence to automatically clean floors, reducing the user's hygiene and cleaning burden. With the recent development of artificial intelligence, more and more cleaning robots are equipped with a base station, which typically houses an air pump and a sewage tank. The sewage tank has an inlet and an outlet. When the cleaning robot returns to the base station, the air pump extracts air from the sewage tank through the outlet, creating a negative pressure in the tank. This negative pressure then pumps the sewage generated by the cleaning robot through the inlet and into the tank.

[0003] To prevent sewage backflow, the sewage tank's sewage inlet is typically positioned relatively high, placing it close to the tank lid. Consequently, during the process of pumping sewage into the tank, the high-speed flow of sewage can easily spray directly onto the tank lid. This not only makes cleaning the lid more difficult but also easily causes corrosion and damage, shortening its service life. Furthermore, high-speed sewage can easily splash onto the exhaust port, potentially damaging the air pump. Utility Model Content

[0004] The embodiments of the present utility model aim to provide a cleaning base station and a cleaning system to solve the technical problem in the prior art that, during the process of recycling sewage into a sewage tank, sewage is easily sprayed directly onto the tank cover, which increases the difficulty of cleaning the tank cover and causes the tank cover to be easily corroded and damaged.

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0039] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art in the field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0040] The following will be combined with the Figures 1 to 11 The cleaning base station and cleaning system provided by the embodiments of the present utility model are described in detail.

[0041] See also Figures 1 to 6 ,in Figure 6 The dashed line represents the flow path of sewage. This embodiment of the utility model provides a cleaning system, comprising a cleaning base station 100 and a cleaning robot. The cleaning robot is used to clean the floor, and the cleaning base station 100 is used to accommodate the cleaning robot. Once the cleaning robot enters the cleaning base station 100, the cleaning base station 100 can perform tasks such as sewage treatment, mop cleaning, and charging for the cleaning robot.

[0042] In some embodiments, the cleaning base station 100 includes a body, a sewage tank 10, a deflector 20 and an air supply member 30. The sewage tank 10 is arranged in the body. The sewage tank 10 includes a box body 11 and a box cover 12. The box cover 12 is arranged on the box body 11. The box body 11 and the box cover 12 are arranged to form a sewage collecting chamber 110. The box body 11 has a boss 111, and the boss 111 is provided with a sewage inlet 1110 and an exhaust hole 113. The deflector 20 is covered on the boss 111 and is located above the sewage inlet 1110. The deflector 20 is provided on the boss 111 and is located above the sewage inlet 1110. The guide cavity 21 is formed by surrounding the boss 111, and the exhaust hole 113 is located on the outside of the guide cavity 21. The guide cavity 21 has a sewage outlet 210, and the sewage inlet 1110 is connected to the guide cavity 21. The sewage outlet 210 is connected to the sewage collecting cavity 110. The air supply member 30 is arranged on the body, and the air supply member 30 is connected to the exhaust hole 113 to form a negative pressure in the sewage collecting cavity 110. Under the action of the negative pressure, the sewage in the cleaning tank flows through the sewage inlet 1110 and the guide cavity 21 in sequence, and flows from the sewage outlet 210 to the sewage collecting cavity 110.

[0043] The body is used to dock the cleaning robot. One sidewall of the body is recessed inward to form a chamber for accommodating the cleaning robot. When the cleaning robot returns to the body, it is located within the chamber. The interior of the body is hollow to form an installation chamber, in which the sewage tank 10, air deflector 20, and air supply member 30 can all be installed.

[0044] The sewage tank 10 includes a box body 11 and a box cover 12. The interior of the box body 11 is hollow and forms a sewage collecting chamber 110. The sewage collecting chamber 110 is used to accommodate the sewage generated during the cleaning process of the cleaning robot. In some embodiments, the sewage generated during the cleaning process of the cleaning robot is collected in the sewage collecting tank of the cleaning robot. When the cleaning robot returns to the base station, the sewage collecting tank can be connected to the base station sewage tank 10, and under the action of the negative pressure generated by the air supply component 30, the sewage in the sewage collecting tank is directly transported to the base station sewage tank 10.

[0045] Optionally, a cleaning trough is provided at the bottom of the accommodating chamber, which can be connected to the dirt collecting chamber 110. When the cleaning robot returns to the accommodating chamber of the body, the cleaning base station 100 can perform a self-cleaning task to clean the cleaning parts (such as a mop) on the cleaning robot. The sewage generated during the cleaning process is collected in the cleaning trough, and under the action of the negative pressure generated by the air supply part 30, the sewage in the cleaning trough is transported to the dirt collecting chamber 110.

[0046] The box cover 12 is arranged on the box body 11, and the box cover 12 can be connected to the box body 11 by means of snap connection, hinge connection, etc. A boss 111 is provided in the box body 11, and the boss 111 can be connected to the bottom wall of the box body 11 or the side wall of the box body 11, or can be formed by the inner concave of the box body 11.

[0047] The sewage inlet 1110 is provided at the top of the boss 111 and is connected to the cleaning tank, so that the sewage inlet 1110 is relatively high vertically inside the sewage tank 10, thereby preventing sewage from flowing back into the cleaning tank through the sewage inlet 1110. Optionally, the cleaning tank and the sewage inlet 1110 can be connected by a hose, so that sewage in the cleaning tank can flow through the hose to the sewage inlet 1110 under the action of negative pressure, and ultimately flow into the sewage collection chamber 110.

[0048] The deflector 20 is located above the sewage inlet 1110 and between the sewage inlet 1110 and the box cover 12. The deflector 20 is installed on the boss 111 and encloses the boss 111 to form a deflector cavity 21 (see Figure 5 ), the diversion chamber 21 is provided with a sewage outlet 210. Optionally, the sewage inlet 1110 and the sewage outlet 210 can be respectively located at opposite ends of the diversion chamber 21. The sewage entering the diversion chamber 21 from the sewage inlet 1110 can flow into the sewage collecting chamber 110 through the sewage outlet 210.

[0049] The air supply member 30 can be a device that can deliver airflow, such as an air pump or a fan. The air supply member 30 has an air inlet 301 and an air outlet 302. The air inlet 301 is connected to the sewage collecting chamber 110 through the exhaust hole 113, and the air outlet 302 is connected to the outside world. Optionally, the air inlet 301 and the exhaust hole 113 are connected by an air pipe, and the air outlet 302 is also connected to the outside world through an air pipe. When the cleaning robot enters the cleaning base station 100, the air supply member 30 is started. Under the action of the air supply member 30, the air flow in the sewage collecting chamber 110 can be discharged to the outside world through the air supply member 30, so that a negative pressure is formed in the sewage collecting chamber 110. Under the action of the negative pressure, the sewage in the cleaning tank flows into the sewage collecting chamber 110 through the sewage inlet 1110, the diversion chamber 21 and the sewage outlet 210 in sequence.

[0050] In this embodiment, the deflector cover 20 is arranged above the sewage inlet 1110 and forms a deflector cavity 21 with the boss 111. The deflector cavity 21 has a diversion effect on the sewage, so that the sewage sprayed from the sewage inlet 1110 is discharged into the sewage collecting cavity 110 of the box body 11 through the deflector cavity 21 and the sewage outlet 210 in turn, thereby preventing the sewage from splashing onto the box cover 12, preventing the sewage from causing impact or corrosion to the box cover 12, reducing the difficulty of cleaning the box cover 12, and extending the service life of the box cover 12.

[0051] It is understandable that, due to the configuration of the air deflector 20 , the box cover 12 can be made of a non-corrosion-resistant material to save the material cost of the box cover 12 .

[0052] In addition, since the sewage inlet 1110 is located on the inner side of the guide cavity 21 and the exhaust hole 113 is located on the outer side of the guide cavity 21, that is, the cover body 201 of the guide cover 20 separates the sewage inlet 1110 and the exhaust hole 113, the sewage inlet 1110 is located on the inner side of the cover body 201, and the exhaust hole 113 is located on the outer side of the cover body 201, the guide cover 20 can prevent sewage from splashing into the exhaust hole 113, thereby preventing the air supply part 30 from being damaged by water.

[0053] In some embodiments, the air deflector 20 can be detachably mounted on the boss 111. For example, the air deflector 20 can be detachably mounted on the boss 111 by snap-fitting, threaded connection, or other detachable means to facilitate disassembly and cleaning of the air deflector 20 to avoid clogging.

[0054] For example, in Figure 3 In the embodiment, the air deflector 20 is provided with a threaded hole 22, through which a fixed connection with the boss 111 can be achieved. In other embodiments, the air deflector 20 can also be configured as an integrally formed structure with the boss 111 to enhance structural compactness and reduce assembly costs.

[0055] like Figure 6As shown, in some embodiments, the guide cavity 21 has a first guide surface 23 on one side facing the box cover 12, and the first guide surface 23 extends from the sewage inlet 1110 toward the sewage outlet 210, and at least a portion of the first guide surface 23 near one end of the sewage outlet 210 is inclined downward.

[0056] The sewage inlet 1110 and the sewage outlet 210 can be located at opposite ends of the diversion chamber 21 respectively. The sewage entering from the sewage inlet 1110 can flow along the diversion chamber 21 to the sewage outlet 210, and flow from the sewage outlet 210 to the sewage collecting chamber 110. The diversion chamber 21 can be a regular or irregular shape. Based on the different structures of the diversion chamber 21, the flow path of the sewage in the diversion chamber 21 can be roughly linear, L-shaped, S-shaped, etc.

[0057] The side of the guide cavity 21 facing the box cover 12 has a first guide surface 23, that is, the first guide surface 23 is the inner surface of the guide cover 20 close to the guide cavity 21. It can be understood that the first guide surface 23 can prevent the sewage at the sewage inlet 1110 from being directly sprayed onto the box cover 12, thereby avoiding corrosion and damage to the box cover 12.

[0058] The first guide surface 23 extends from the sewage inlet 1110 toward the sewage outlet 210. In the area near the sewage outlet 210 and from the sewage inlet 1110 toward the sewage outlet 210, a portion of the first guide surface 23 may be tilted downward, for example Figure 6 In the figure, the first guide surface 23 includes a first sub-surface 231, which is close to the sewage outlet 210 and is arranged to be inclined downward. In addition, the entire first guide surface 23 can also be arranged to be inclined downward.

[0059] By tilting a portion of the first guide surface 23 (such as the first sub-surface 231) downward, or tilting the entire first guide surface 23 downward, so that the opening direction of the sewage outlet 210 is roughly toward the bottom of the box body 11, the first guide surface 23 has a downward guiding effect on the sewage in the guide cavity 21, so that the sewage can flow tilted downward along the first guide surface 23 and flow into the sewage collection tank through the sewage outlet 210, thereby preventing the sewage from splashing upward onto the box cover 12, reducing the difficulty of cleaning the box cover 12, and reducing the risk of the box cover 12 being corroded or damaged.

[0060] In addition, the first guide surface 23 is arranged to be inclined downward. The guiding effect of the first guide surface 23 helps the sewage in the diversion cavity 21 to be smoothly discharged into the sewage collection tank, thereby preventing the sewage from being retained or turbulent in the diversion cavity 21.

[0061] In some embodiments, the first guide surface 23 also includes a second sub-surface 232, which can be a sloped surface or an arc-shaped surface. The second sub-surface 232 is located above the sewage inlet 1110, and the second sub-surface 232 extends from the sewage inlet 1110 toward the sewage outlet 210. The second sub-surface 232 is tilted upward.

[0062] The second sub-surface 232 is located above the sewage inlet 1110, and points from the end of the second sub-surface 232 close to the sewage inlet 1110 to the end of the second sub-surface 232 away from the sewage inlet 1110. The second sub-surface 232 is tilted upward to divert the sewage. On the one hand, the sewage flowing out of the sewage inlet 1110 will flow upward along the second sub-surface 232 after being sprayed onto the second sub-surface 232, thereby preventing the sewage from flowing back into the sewage inlet 1110. On the other hand, the second sub-surface 232 is tilted upward to reduce the impact force of the sewage on the second sub-surface 232, thereby preventing the sewage from impacting the second sub-surface 232 perpendicularly and causing damage to the second sub-surface 232.

[0063] In some embodiments, the first guide surface 23 further includes a third sub-surface 233 , which is disposed between the first guide surface 23 and the second sub-surface 232 . The third sub-surface 233 is connected to the first sub-surface 231 and the second sub-surface 232 , respectively, and is relatively horizontally disposed.

[0064] like Figure 6 As shown, the third sub-surface 233 is located between the second sub-surface 232 and the first sub-surface 231. The second sub-surface 232 and the first sub-surface 231 can be smoothly transitioned through the third sub-surface 233, so that the sewage on the second sub-surface 232 can be smoothly transitioned to the first sub-surface 231 through the third sub-surface 233, reducing the eddy current or turbulence caused by the change in direction, so that the sewage in the guide cavity 21 can flow along the planned path, ensuring the smoothness of the sewage flow.

[0065] In some embodiments, the guide cavity 21 has a second guide surface 112 on one side facing the boss 111, the first guide surface 23 is arranged opposite to the second guide surface 112, and the second guide surface 112 extends from an end close to the sewage inlet 1110 toward an end close to the sewage outlet 210, and at least a portion of the second guide surface 112 close to the sewage outlet 210 is arranged to be inclined downward.

[0066] The inner bottom surface of the diversion cavity 21 includes a second diversion surface 112, which is arranged opposite to the first diversion surface 23. From one end of the second diversion surface 112 away from the sewage outlet 210 to the other end of the second diversion surface 112 facing the sewage outlet 210, the second diversion surface 112 is arranged to be inclined downward.

[0067] like Figure 6As shown, the second guide surface 112 can be the upper surface of the boss 111. In addition, when the deflector 20 has an upper and lower surface structure (i.e., when the bottom of the deflector 20 is a non-hollow structure), the second guide surface 112 can also be the inner bottom surface of the deflector 20 near the boss 111. The second guide surface 112 is arranged to be inclined downward, which helps the sewage and debris in the sewage flow along the second guide surface 112 into the sewage collecting chamber 110, and prevents the debris in the sewage from being deposited on the second guide surface 112.

[0068] See also Figure 2 、 Figure 3 and Figure 7 In some embodiments, an exhaust port 28 is provided on the air guide cover 20, and the air supply member 30 is connected to the sewage collecting chamber 110 through the exhaust port 28. A baffle 29 is also protruding from the air guide cover 20, and the exhaust port 28 and the sewage outlet 210 are separated by the baffle 29.

[0069] The exhaust port 28 corresponds to the exhaust hole 113 and is connected to it. In this way, after the air supply member 30 is started, the air flow in the sewage collecting chamber 110 can be discharged to the outside after passing through the exhaust port 28, the exhaust hole 113 and the air inlet 301 and the air outlet 302 of the air supply member 30 in sequence, thereby forming a negative pressure in the sewage collecting chamber 110.

[0070] Baffle 29 is provided on shroud 20 and can be integrally formed with shroud 20 to ensure the structural strength of shroud 20. Baffle 29 separates exhaust port 28 from sewage outlet 210, further preventing moisture at sewage outlet 210 from flowing into exhaust port 28 and into air supply member 30 through exhaust port 28, thereby preventing water vapor from being damaged by water ingress.

[0071] Optionally, the baffle 29 is arranged at the periphery of the sewage outlet 210 . The baffle 29 is closer to the sewage outlet 210 and farther from the exhaust port 28 , which can further prevent water vapor at the sewage outlet 210 from flowing to the exhaust port 28 .

[0072] See also Figure 2 and Figure 3 In some embodiments, the cleaning base station 100 further includes a connecting rod 41 and a float 42 and an exhaust cover 43 respectively arranged at both ends of the connecting rod 41. The connecting rod 41 is rotatably mounted on the air deflector 20. The float 42 can float up and down with the water level to drive the connecting rod 41 to rotate relative to the air deflector 20, so that the exhaust cover 43 opens or closes the exhaust port 28 and the exhaust hole 113.

[0073] The float 42 floats up and down with the water level. When the water level rises, the float 42 rises, and when the water level drops, the float 42 sinks. As the float 42 floats up and down, the connecting rod 41 rotates accordingly. The rotation of the connecting rod 41 drives the position of the exhaust cover 43 to change, causing the exhaust cover 43 to open or close the exhaust port 28 and the exhaust hole 113.

[0074] Specifically, when the water level in the sewage collecting chamber 110 is low, the position of the float 42 in the sewage collecting chamber 110 is relatively low. At this time, the exhaust cover 43 is in the open state, and the air supply part 30 is started. Under the action of the air supply part 30, the air flow in the sewage collecting chamber 110 will be discharged through the exhaust port 28, so that a negative pressure is formed in the sewage collecting chamber 110. Under the action of the negative pressure, the sewage in the cleaning tank flows into the sewage collecting chamber 110 through the sewage inlet 1110, the guide chamber 21 and the sewage outlet 210 in turn. As the sewage flows in, the water level in the sewage collecting chamber 110 will gradually rise, causing the float 42 to rise and drive the connecting rod 41 and the exhaust cover 43 to rotate. When the water level rises to a certain height, the exhaust cover 43 closes the exhaust port 28 and the exhaust hole 113 to prevent sewage from entering the air supply part 30 through the exhaust port 28 and the exhaust hole 113 in turn.

[0075] In this embodiment, the deflector 20 can not only divert the sewage to prevent it from being sprayed onto the upper cover, but the deflector 20 can also be used to install components such as the connecting rod 41 and the exhaust cover 43, thereby eliminating the need for additional components to assemble the connecting rod 41, the exhaust cover 43 and other components, thereby helping to reduce the number of components and lower costs.

[0076] In some embodiments, a sealing ring may be provided at the exhaust port 28. When the exhaust cover 43 is positioned over the exhaust port 28, the exhaust cover 43 and the sealing ring seal together to prevent sewage from entering the exhaust port 28. Furthermore, the exhaust cover 43 may be made of a material with good sealing properties, such as silicone, to further enhance the sealing effect of the exhaust port 28.

[0077] See also Figure 8 In some embodiments, a rotating shaft is provided on the connecting rod 41, and a rotating shaft hole 26 is provided on the air deflector 20. The rotating shaft of the connecting rod 41 is installed in the rotating shaft hole 26 to achieve a rotational connection between the two. It is understood that in other embodiments, a rotating shaft hole may be provided on the connecting rod 41, and a rotating shaft may be provided on the air deflector 20 to achieve a rotational connection between the two.

[0078] See also Figure 2 、 Figure 8 、 Figure 9 and Figure 10In some embodiments, the air guide cover 20 includes a cover body 201 and a base 202 connected to each other. The cover body 201 cooperates with the boss 111 to form a guide cavity 21. The exhaust port 28 is opened on the base 202. There is a gap between the bottom of the base 202 and the boss 111 to form a hollow groove 203.

[0079] The base 202 and the cover 201 are respectively arranged above the boss 111 . Optionally, the base 202 and the cover 201 are integrally formed to ensure the structural strength of the air duct 20 .

[0080] The exhaust port 28 can be opened in the middle of the base 202. The bottom two sides of the base 202 are hollowed out and cooperate with the boss 111 to form a hollow groove 203. The hollow groove 203 facilitates the cleaning of the deflector 20 to prevent it from being blocked by debris in the sewage.

[0081] In some embodiments, a connecting column 2020 is provided at the bottom of the base 202 (see Figure 8 ), a threaded hole 22 is opened in the connecting column 2020, and the threaded hole 22 is used to achieve a fixed connection between the air deflector 20 and the boss 111.

[0082] Please refer back to Figure 1 In some embodiments, the cleaning base station 100 further includes an air pipe 50, the air supply member 30 is an air pump, the air pump includes a pump body 31 and a motor 32 arranged above the pump body 31, the pump body 31 is provided with an air inlet 301, the air inlet 301 is connected to the exhaust hole 113 through the air pipe 50, and the horizontal height of the lowest point of the air pipe 50 is lower than the horizontal height of the air inlet 301.

[0083] like Figure 1 As shown, when the air pump is started, the air flow in the dirt collecting chamber 110 passes through the exhaust port 28, the exhaust hole 113, the air pipe 50, and the air inlet 301 and the air outlet 302 of the air pump in sequence and is then discharged to the outside.

[0084] The lowest point of the air pipe 50 is lower than the level of the air inlet 301, so that part of the liquid entering the air pipe 50 from the exhaust port 28 can be stored in the air pipe 50, which can effectively prevent the liquid in the air pipe 50 from flowing into the air inlet 301 of the air pump under the action of its own gravity, thereby preventing the air pump from being damaged by water.

[0085] The motor 32 is located directly above the pump body 31, and the air inlet 301 is set on the pump body 31. The horizontal height of the air inlet 301 is lower than the horizontal height of the motor 32, which can further prevent water vapor or liquid in the air inlet 301 from entering the motor 32 and causing the motor 32 to be damaged by water.

[0086] See also Figure 11In some embodiments, the cleaning base station 100 further includes a drain pipe, which is installed in the sewage collecting chamber 110. The air guide cover 20 includes a drain connector 27, which has a drain port 210. One end of the drain pipe is connected to the drain connector 27, and the other end is connected to the sewage collecting chamber 110.

[0087] like Figure 11 As shown, the air deflector 20 includes a drain connector 27, which can be arranged on the side of the air deflector 20 and connected to the sewage collecting chamber 110. The drain pipe can be a hose made of plastic or metal material to facilitate assembly connection with the drain connector 27. Optionally, one end of the drain pipe is connected to the drain connector 27, and the other end is connected to the bottom of the sewage collecting chamber 110.

[0088] When the air supply member 30 is started, the air supply member 30 draws away the air flow in the sewage collecting chamber 110 to form a negative pressure in the sewage collecting chamber 110. Under the action of the negative pressure, the sewage in the cleaning tank flows into the diversion chamber 21 through the sewage inlet 1110. The diversion chamber 21 has a buffering effect on the sewage to reduce the impact force of the sewage. Then the sewage in the diversion chamber 21 flows into the sewage collecting chamber 110 through the sewage discharge joint 27 and the sewage discharge pipe, avoiding the sewage flowing out of the sewage inlet 1110 directly spraying onto the box cover 12, causing corrosion damage to the box cover 12.

[0089] In some embodiments, a sewage pipe may not be provided. In this case, the opening direction of the sewage connector 27 can be configured to face the bottom of the sewage collecting chamber 110, and the sewage is guided to flow into the sewage collecting chamber 110 through the sewage connector 27 to prevent the sewage from splashing onto the box cover 12.
