[0033] The present invention provides a cleaning robot. Please refer to Figures 1 to 3 , the cleaning robot 1000 includes a machine body 100, a rolling brush 200, and an air flow generating device 300. The rolling brush 200 is used to perform cleaning operations on the ground (such as vacuuming, mopping, floor washing, etc.), and the air flow generating device 300 is used to perform a drying operation on the rolling brush 200.

[0034] The machine body 100 not only serves as a supporting structure for other components of the cleaning robot 1000 (such as the main control module, the walking module, etc.), but also acts as an appearance component of the cleaning robot 1000. There are many shapes for the machine body 100. It can be set in a cylindrical shape, or it can be in a D shape, or it can be in a square shape. Specific limitations are not made here.

[0035] The machine body 100 is provided with a cleaning cavity 100a with an open lower end. The cleaning cavity 100a is used to accommodate the rolling brush 200. The cleaning cavity 100a can be communicated with the dust collection box of the cleaning robot 1000, or it can also be communicated with the sewage tank 116 of the cleaning robot 1000, so that dust, debris, sewage, etc. raised when the rolling brush 200 works can be recycled.

[0036] The rolling brush 200 has a structure that can perform cleaning operations on the ground when rotating. The rolling brush 200 can be formed by a rotating shaft and bristles. At this time, the rolling brush 200 can perform dust removal or floor washing operations on the ground. The rolling brush 200 can also be formed by a rotating shaft and a mop. At this time, the rolling brush 200 can perform mopping operations on the ground.

[0037] The rotary brush 200 is rotatably installed in the cleaning cavity 100a and is in clearance fit with the cavity wall of the cleaning cavity 100a. The two axial ends of the rotary brush 200 are rotatably connected to the machine body 100. There are many ways to rotatably connect the rotary brush 200 to the machine body 100. For example, the rotary brush 200 and the machine body 100 are rotatably connected through a rotating shaft and a bearing. Another example is that the rotary brush 200 and the machine body 100 are rotatably connected through a rotating shaft and a bushing.

[0038] When the rotary brush 200 is installed in the cleaning cavity 100a, a part of it extends out from the opening of the cleaning cavity 100a so that the outer peripheral wall of the rotary brush 200 can contact the surface to be cleaned. For example, the volume of the rotary brush 200 extending out from the opening of the cleaning cavity 100a is one-fourth of its own volume. Another example is that the volume of the rotary brush 200 extending out from the opening of the cleaning cavity 100a is one-fifth of its own volume. No specific limitation is made here.

[0039] The air flow generating device 300 is a device capable of driving air flow. The air flow generating device 300 can be a blower, an air pump, etc. The air flow generating device 300 is mainly used to drive the air flow around the rotary brush 200. That is, the air flow generating device 300 can be such that its air inlet end is communicated with the cleaning cavity 100a, or its air outlet end is communicated with the cleaning cavity 100a, or both the air inlet end and the air outlet end are communicated with the cleaning cavity 100a.

[0040] Preferably, the air outlet end of the air flow generating device 300 is arranged towards the rotary brush 200. Under the action of the air flow generating device 300, the air is accelerated. After the fast-flowing air blows towards the rotary brush 200, it can accelerate the evaporation of the moisture on the rotary brush 200, thereby facilitating the improvement of the air-drying speed of the rotary brush 200.

[0041] The air flow generating device 300 is installed on the machine body 100. The air flow generating device 300 can be installed inside the machine body 100, or it can also be installed outside the machine body 100. Preferably, the air flow generating device 300 is installed inside the machine body 100. In this way, not only can the appearance of the cleaning robot 1000 be kept flat, but also the air flow generating device 300 can be prevented from being exposed outside and damaged.

[0042] When the cleaning robot 1000 cleans the ground, the control module of the cleaning robot 1000 controls the walking module and the rotary brush 200 to work. The walking module drives the entire cleaning robot 1000 to move forward on the ground. When the cleaning robot 1000 is a vacuuming robot, the rotary brush 200 raises dirt such as dust and debris on the ground. When the cleaning robot 1000 is a mopping robot, the rotary brush 200 effectively mops the stains on the ground.

[0043] After the rotary brush 200 of the cleaning robot 1000 finishes the cleaning work, the air flow generating device 300 drives the air to flow, so that the air with a certain flow velocity passes through the rotary brush 200, thereby accelerating the air flow velocity around the rotary brush 200, which is beneficial to keeping the rotary brush 200 dry and avoiding the problems of mildew and odor of the rotary brush 200.

[0044] It should be noted that most of the rotary brush 200 is accommodated in the cleaning cavity 100a. If the air flow generating device 300 blows air from outside the cleaning cavity 100a into the cleaning cavity 100a, the air not only needs to enter from the open end of the cleaning cavity 100a but also needs to be discharged from the open end of the cleaning cavity 100a. In this way, the amount of air entering and leaving the cleaning cavity 100a per unit time is relatively small, which affects the air drying speed of the rotary brush 200.

[0045] In view of the above problems, the air outlet end of the air flow generating device 300 is communicated with the cleaning cavity 100a. The air flow generating device 300 drives the external air to enter the cleaning cavity 100a and finally blows it out through the open end of the cleaning cavity 100a. In this way, it can be ensured that only air blows out from the open end of the cleaning cavity 100a, ensuring the air output per unit time, and thus ensuring the air drying speed of the rotary brush 200.

[0046] Specifically, please refer to Figures 1 to 4 On the machine body 100, there is an air outlet hole 100b. The air inlet ends of the air outlet holes 100b are all communicated with the air flow generating device 300. The air outlet ends of the air outlet holes 100b are communicated with the cleaning cavity 100a and are arranged facing the rotary brush 200. The air flow generating device 300 can blow air into the cleaning cavity 100a through the air outlet holes 100b. In this way, the air in the cleaning cavity 100a is limited to only one flow direction, which is beneficial to ensuring the air flow velocity in the cleaning cavity 100a.

[0047] It should be noted that the number of the air outlet holes 100b can be one or more. When the number of the air outlet holes 100b is one, the air outlet hole 100b can extend along the axial direction of the rotary brush 200 and is arranged in a flat shape. In this way, it can not only ensure that the air outlet area of the air outlet hole 100b covers the entire rotary brush 200 in the axial direction of the rotary brush 200, but also ensure the air outlet speed of the air outlet hole 100b, so as to ensure the air drying speed of the rotary brush 200.

[0048] When the number of the air outlet holes 100b is multiple, the multiple air outlet holes 100b are arranged at intervals along the axial direction of the rotary brush 200. The areas covered by the air blown out from two adjacent air outlet holes 100b partially overlap or are just adjacent in the length direction of the rotary brush 200. The air blown out from the multiple air outlet holes 100b can cover the entire rotary brush 200 in the length direction of the rotary brush 200.

[0049] Since the middle part of the rotary brush 200 plays a major role in cleaning the ground, when the number of the air outlet holes 100b is multiple, the number of the air outlet holes 100b facing the middle position of the rotary brush 200 is more than that of the air outlet holes 100b facing the two ends of the rotary brush 200. With such a setting, the amount of air blown to the middle part of the rotary brush 200 is more than that blown to the two ends of the rotary brush 200, thus facilitating the air drying of the rotary brush 200.

[0050] Furthermore, a ventilation channel 100c is provided on the machine body 100. The ventilation channel 100c is communicated with the air flow generating device 300, and the ventilation channel 100c is also communicated with the air outlet holes 100b. Compared with the scheme of connecting the air flow generating device 300 and the air outlet through an external pipeline, in this technical solution, by integrating the ventilation channel 100c on the machine body 100, the structure of the machine body 100 is made more compact. At the same time, the setting of external pipelines can be reduced, and the layout of the air path of the cleaning robot 1000 is simplified.

[0051] It should be noted that there are many ways to form the above-mentioned ventilation channel 100c. The ventilation channel 100c can be formed by a pipeline structure on the machine body 100, or the ventilation channel 100c can be formed by enclosing several structural members of the machine body 100. Considering that there are usually tiny particles in the air in the environment, scale of tiny particles will be formed in the ventilation channel 100c after long-term use, thus affecting the ventilation effect of the ventilation channel 100c. In view of this, the ventilation channel 100c is formed by enclosing at least two detachable structural members.

[0052] Specifically, the machine body 100 includes a body structure 110 and a surrounding plate 120. The cleaning cavity 100a is formed in the body structure 110. The ventilation channel 100c is formed by jointly enclosing the body structure 110 and the surrounding plate 120. The air outlet holes 100b are formed in the body structure 110 and / or the surrounding plate 120. With such a setting, when maintenance of the ventilation channel 100c is required, only the surrounding plate 120 needs to be detached from the body structure 110, thus facilitating the cleaning and maintenance of the ventilation channel 100c.

[0053] It should be noted that there are many ways to connect the surrounding plate 120 and the body structure 110. The surrounding plate 120 can be connected to the body structure 110 by a snap connection method, the surrounding plate 120 and the body structure 110 can be connected by screws, and other connection methods can also be adopted between the surrounding plate 120 and the body. They are not listed one by one here.

[0054] Preferably, the enclosure 120 is connected to the body structure 110 by means of insertion. An assembly groove 111 is recessed on the surface of the body structure 110 adjacent to the cleaning chamber 100a. The assembly groove 111 is arranged in a long strip shape along the axial direction of the roller brush 200. The assembly groove 111 can also be arranged in a zigzag shape along the axial direction of the roller brush 200, and no specific limitation is made here.

[0055] The shape of the enclosure 120 is adapted to the shape of the assembly groove 111. The cross-section of the enclosure 120 is arranged in a "U" shape. In this way, when the enclosure 120 and the body structure 110 are assembled, the enclosure 120 can be directly inserted into the assembly groove 111. At this time, the air outlet hole 100b is preferably arranged on the enclosure 120, which is not only convenient for maintaining the ventilation channel 100c, but also convenient for the setting and maintenance of the air outlet hole 100b.

[0056] Furthermore, a reinforcing rib plate 121 protrudes from the surface of the enclosure 120 facing the bottom of the assembly groove 111. The width of the reinforcing rib plate 121 is smaller than the width of the assembly groove 111 or a hole structure for air passage is provided through the reinforcing rib plate 121. A limiting groove 112 that is inserted and matched with the reinforcing rib plate 121 is correspondingly arranged at the bottom of the assembly groove 111. With such a setting, the enclosure 120 can be effectively supported, avoiding the problem that the enclosure 120 is deformed due to external force extrusion, and then causing the local reduction or blockage of the ventilation channel 100c.

[0057] It should be noted that the reinforcing rib plate 121 can be one or more. When the reinforcing rib plate 121 is one, the reinforcing rib plate 121 is located at the middle position of the enclosure 120. When the reinforcing rib plate 121 is multiple, multiple reinforcing rib plates 121 are arranged at intervals in the length direction of the enclosure 120. Correspondingly, the number and position of the limiting grooves 112 provided at the bottom of the assembly groove 111 are arranged corresponding to the reinforcing rib plate 121.

[0058] It should be noted that a variety of components of the cleaning robot 1000 are assembled on the machine body 100. In order to ensure that the volume of the cleaning robot 1000 is appropriate, the position of the air flow generating device 300 needs to be set according to the actual situation. That is to say, there is a situation where the air flow generating device 300 cannot be directly communicated with the ventilation channel 100c. In view of this, please refer to Figures 1 to 5 A transfer channel 100d is provided on the body structure 110. One end of the transfer channel 100d is communicated with the ventilation channel 100c, and the other end of the transfer channel 100d is communicated with the air flow generating device 300. In this way, the installation position of the air flow generating device 300 is not restricted by the ventilation channel 100c, which is convenient for the layout of each component in the cleaning robot 1000.

[0059] It should be noted that the formation method of the transfer channel 100d is the same as that of the ventilation channel 100c. That is, the transfer channel 100d can be formed by a tubular structure on the machine body 100, or can be formed by enclosing at least two components in the machine body 100. Preferably, the transfer channel 100d is formed by enclosing at least two components in the machine body 100, which is convenient for cleaning and maintaining the interior of the transfer channel 100d.

[0060] Specifically, a groove 113 communicating with the ventilation channel 100c is recessed on the surface of the body structure 110. The groove 113 can be located on the bottom surface, side surface and top surface of the body structure 110. The setting position of the groove 113 can be set according to specific situations. The machine body 100 further includes a cover plate 130, and the cover plate 130 is used to cover the notch of the groove 113 to enclose and form the transfer channel 100d together with the body structure 110. With such a setting, it is convenient for cleaning and maintaining the transfer channel 100d.

[0061] There are many connection methods between the cover plate 130 and the groove 113. The cover plate 130 and the groove 113 can be connected to the body structure 110 by snap connection. The cover plate 130 and the body structure 110 can be connected by screws. Other connection methods can also be adopted between the cover plate 130 and the body, which will not be listed one by one here.

[0062] Preferably, the cover plate 130 and the body structure 110 are connected by a plug-in method. The body structure 110 is recessed with a plug-in groove 114 on the periphery of the groove 113. The plug-in groove 114 can extend along the periphery of the groove 113 and be arranged in a ring shape, or can be arranged at intervals along the periphery of the groove 113, or can also be a section extending along the periphery of the groove 113, which is not specifically limited here.

[0063] A plug-in plate 131 is correspondingly arranged on the surface of the cover plate 130 facing the groove 113. The shape of the plug-in plate 131 is adapted to the shape of the plug-in groove 114. The plug-in plate 131 and the plug-in groove 114 are connected by a plug-in method. Plugging has the advantages of convenient assembly and disassembly, so it is convenient for the assembly and disassembly of the cover plate 130 and the body structure 110.

[0064] In order to further improve the air-drying speed of the roller brush 200, a heating device (not shown) can also be provided at the air outlet end of the air flow generating device 300. The heating device can be an electric heating wire, a heating ceramic sheet and other devices that can generate heat. The heating device can heat the air, so that the temperature of the air passing through the heating device can be increased. When the high-temperature air quickly passes through the roller brush 200, the air-drying efficiency of the roller brush 200 can be further improved.

[0065] It should be noted that in the above embodiments, when the cleaning robot 1000 is a floor sweeping robot, the body structure 110 can be the housing 115 of the cleaning robot 1000 or an assembly of the housing 115 and the dust collection box. When the cleaning robot 1000 is a mopping robot or a mopping and sweeping integrated machine, the body structure 110 can be the housing 115 or an assembly of the housing 115 and the water tank 116. For the convenience of description, the following takes the assembly of the housing 115 and the water tank 116 as an example of the body structure 110 for detailed description.

[0066] Please refer to Figures 1 to 5 , the body structure 110 includes a housing 115 and a water tank 116. The water tank 116 is installed on the housing 115. The water tank 116 and the housing 115 jointly define a cleaning cavity 100a. The ventilation channel 100c and the transfer channel 100d can be provided on the housing 115, or can be provided on the water tank 116, or can be distributed on both the housing 115 and the water tank 116 at the same time. Considering that the housing 115 itself needs to assemble a variety of components, therefore, the ventilation channel 100c and the transfer channel 100d are preferably provided on the water tank 116. This can not only avoid the complication of the structure of the housing 115, but also make full use of the space on the water tank 116.

[0067] Specifically, please refer to Figure 4 and Figure 5 , an assembly groove 111 is recessed on the surface of the water tank 116 adjacent to the cleaning cavity 100a, and a groove 113 is recessed on the surface of the water tank 116 on one side thereof. The apron 120 is connected to the water tank 116 to cover the assembly groove 111, and the cover plate 130 is connected to the water tank 116 to cover the groove 113. In this way, the above ventilation channel 100c and transfer channel 100d are formed on the water tank 116. In this way, while ensuring the simplification of the structure of the water tank 116, the ventilation channel 100c and the transfer channel 100d are integrated on the water tank 116, making the structure of the water tank 116 more compact.

[0068] Furthermore, the air flow generating device 300 is installed on the upper surface of the housing 115. A receiving recess 1161 is recessed in a part of the lower surface of the water tank 116 and an air inlet 1162 is located in the receiving recess 1161. The air inlet 1162 is communicated with the ventilation channel 100c. When the water tank 116 is assembled onto the housing 115 from top to bottom, the air flow generating device 300 extends into the receiving recess 1161, and the air flow generating device 300 is also docked and communicated with the air inlet 1162.

[0069] With such an arrangement, the air flow generating device 300 can be communicated with the air inlet 1162 through the assembly of the water tank 116 and the outer shell 115, which simplifies the assembly process of the cleaning robot 1000 and thus helps improve the cleaning efficiency of the cleaning robot 1000. In addition, by hiding the air flow generating device 300 between the outer shell 115 and the water tank 116, the volume of the cleaning robot 1000 can be ensured not to be too large.

[0070] Furthermore, please also refer to Figure 6 and Figure 7 , the cleaning robot 1000 further includes a docking joint 400. The docking joint 400 is fixed to the outer shell 115. One end of the docking joint 400 is communicated with the air outlet end of the air flow generating device 300, and the other end of the docking joint 400 faces the water tank 116 and is used for docking and mating with the air inlet 1162. With such an arrangement, it is further convenient for the air flow generating device 300 to communicate with the air inlet 1162.

[0071] It should be noted that the docking joint 400 can be sleeved outside the air inlet 1162, or can be inserted into the air inlet 1162, and no specific limitation is made here. Please refer to Figure 7 , by way of example and not limitation, the docking joint 400 is inserted into the air inlet 1162. The plug joint includes a plug pipe 410 and a sealing skirt 420. One end of the plug pipe 410 is connected to the air flow generating device 300, and the other end of the plug pipe 410 faces the water tank 116. The sealing skirt 420 is arranged at the end of the plug pipe 410 facing the water tank 116. The sealing skirt 420 is arranged in a conical shape, and the sealing skirt 420 deforms when the plug pipe 410 is inserted and mated with the air inlet 1162, so as to seal and connect the plug pipe 410 and the air inlet 1162.

[0072] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
