Any embodiment described in this application as "exemplary" is not necessarily to be construed as being preferred or advantageous over other embodiments. In order to enable any technician in the field to implement and use the utility model, the following description is given. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the utility model can be implemented without using these specific details.

Therefore, the utility model is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0040] In the related art, when the cleaning robot needs to remove the drum for cleaning or maintenance, the robot needs to be turned over and the drum needs to be removed from the bottom. However, this method not only causes wear and tear on the top of the robot, but also makes the top unclean. At the same time, the operation is cumbersome, affecting the user experience.

[0041] In view of this, the present application provides a cleaning robot, by setting a side opening on the side of the shell, the roller is configured to enter and exit the mounting groove through the side opening, so that the roller in the present application can be directly disassembled and assembled from the side of the shell, thereby improving the operating convenience of the cleaning robot.

[0042] To facilitate understanding, the cleaning robot in this application is further described below in conjunction with the accompanying drawings.

[0043] See also Figures 1 to 3 The embodiment of the present application provides a cleaning robot 100, which is used for cleaning work in a home environment, a shopping mall environment, an office environment, etc. The cleaning robot 100 in the present application includes a housing 110 and a drum module 120. The housing 110 includes a bottom surface 111 and a side surface 112 arranged at an angle to the bottom surface 111.

[0044] It should be noted that, in the present application, the bottom surface 111 of the housing 110 refers to a side of the cleaning robot 100 that is adjacent to and directly opposite to the surface to be cleaned when the cleaning robot 100 is working. Exemplarily, the surface to be cleaned is the ground, and the bottom surface 111 of the housing 110 refers to a side that is close to and directly opposite to the ground. In the present application, the shape of the bottom surface 111 is not specifically limited. Exemplarily, the outer contour of the bottom surface 111 is generally circular. Of course, in other embodiments of the present application, the bottom surface 111 may also be elliptical, square, polygonal, etc.

[0045] In the present application, the bottom surface 111 and the side surface 112 are arranged at an angle to enclose a mounting cavity, and the mounting cavity can be used to install components such as the electric control board, and / or battery, and / or water supply assembly of the cleaning robot 100. The shape of the side surface 112 and the connection relationship between the side surface 112 and the bottom surface 111 are not limited. For example, Figure 1 and Figure 2 As shown, the side surface 112 is disposed on the side of the bottom surface 111 away from the ground, and the side surface 112 is generally annular, and the side surface 112 is generally perpendicular to the bottom surface 111. The side surface 112 and the bottom surface 111 can be an integrally formed structure or a detachable connection, which is not limited here.

[0046] In the present application, a mounting groove 113 is provided on the bottom surface 111, and the mounting groove 113 extends along the length direction of the roller 121; the roller 121 is rotatably disposed in the mounting groove 113, for example, at least part of the circumference of the roller 121 protrudes from the bottom surface 111 to clean the surface to be cleaned.

[0047] It is understandable that, since the roller 121 is rotatably arranged in the mounting groove 113, and at least part of the circumference of the roller 121 protrudes from the bottom surface 111. When the cleaning robot 100 in the present application is working, the part of the roller 121 protruding from the bottom surface 111 can contact the surface to be cleaned, and the roller 121 can rotate relative to the surface to be cleaned under the action of the driving force, thereby achieving the cleaning function. It should be noted that the specific method of the roller 121 being rotatably arranged in the mounting groove 113 does not belong to the main improvement point of the present application. Please refer to the following description for details, and it is not limited here.

[0048] In the present application, the mounting groove 113 is used to mount the drum 121. The shape and size of the mounting groove 113 and the drum 121 do not belong to the main improvement points of the present application and are not limited here. Those skilled in the art can reasonably set the shape and size of the drum 121 and the mounting groove 113, that is, the drum 121 can be rotatably located in the mounting groove 113, and the portion of the drum 121 protruding from the bottom surface 111 can contact the surface to be cleaned. Exemplarily, the size and shape of the mounting groove 113 are adapted to the size and shape of the drum 121, the width of the mounting groove 113 is slightly larger than the diameter of the drum 121, the length of the mounting groove 113 is slightly larger than the length of the drum 121, and the depth of the mounting groove 113 is slightly smaller than the diameter of the drum 121. Further, the bottom surface 111 is generally circular, the mounting groove 113 is generally square, the mounting groove 113 is located near the center of the bottom surface 111, and the extension direction of the mounting groove 113 is generally parallel to the diameter of the bottom surface 111.

[0049] In the present application, a side opening 1121 is provided on the side surface 112 at a position opposite to the mounting groove 113, the side opening 1121 is communicated with the mounting groove 113, and the roller 121 is configured to enter and exit the mounting groove 113 through the side opening 1121. Exemplarily, a side opening 1121 is provided on one end of the side surface 112 directly opposite to the mounting groove 113.

[0050] In the present application, a side opening 1121 is provided on the side 112 of the shell 110, and the side opening 1121 is connected to the mounting groove 113. The drum 121 is configured to enter and exit the mounting groove 113 through the side opening 1121, so that the drum 121 in the present application can be directly disassembled and assembled from the side 112 of the shell 110, thereby improving the operational convenience.

[0051] It should be noted that in the related art, one end of the drum 121 of the cleaning robot 100 is connected to the motor drive, and the other end of the drum 121 (that is, the disassembly end of the drum 121) is limited by a snap-on structure against the side wall, and the side wall needs to meet certain wall thickness requirements (the side wall body and the snap-on structure on the side wall need to be thicker, and the side wall body and the snap-on structure on the side wall need to be larger in the length direction of the drum), which leads to the problem that the length of the drum 121 becomes shorter and the cleaning area is reduced.

[0052] In some embodiments of the present application, one end of the drum 121 extends to the side opening 1121. It should be noted that in the present application, one end of the drum 121 extending to the side opening 1121 means that one end of the drum 121 extends into the side opening 1121, or one end of the drum 121 extends to a position close to the side opening 1121 (for example, there is a small gap between the end of the drum 121 close to the side opening and the surface where the side opening 1121 is located. Compared with the prior art, in this embodiment, since the drum 121 is assembled from the side opening 1121 of the housing 110, one end of the drum 121 (that is, the end of the drum 121 close to the side opening 1121) can extend to the side opening 1121, thereby increasing the length of the drum 121, thereby improving the cleaning area and efficiency of the cleaning robot 100.

[0053] In some embodiments of this application, please refer to Figure 3 and Figure 4 , the roller module 120 also includes a support inner core 122, the support inner core 122 extends along the length direction of the roller 121, and the roller 121 is sleeved on the support inner core 122. It can be understood that in this embodiment, by arranging the support inner core 122 in the roller 121, the roller 121 is sleeved on the support inner core 122, which is conducive to improving the stability of the roller 121 and avoiding deformation of the roller 121 during operation. It should be noted that in the present application, the roller 121 sleeved on the support inner core 122 can be the roller 121 directly sleeved on the support inner core 122, or the roller 121 can be sleeved on the support inner core 122 through a medium (such as a transmission member 124), which is not limited here.

[0054] Specifically, the support inner core 122 is generally in the shape of a circular tube, the outer diameter of the support inner core 122 is smaller than the inner diameter of the roller 121, and the length of the support inner core 122 is slightly smaller than the length of the roller 121, so that the support inner core 122 in the present application can better support the roller 121. Exemplarily, the support inner core 122 and the roller 121 are fixedly connected by a transmission member 124, and the support inner core 122, the roller 121 and the transmission member 124 are coaxially arranged, and please refer to the following description for details. Of course, in other embodiments of the present application, the roller 121 can also be directly fixed on the support inner core 122, which is not limited here.

[0055] In some embodiments of the present application, the drum module 120 further includes a driving member 123, the driving member 123 is disposed at an end of the mounting groove 113 away from the side opening 1121, the drum 121 includes an inner drum end (i.e., an end of the drum away from the side opening) and an outer drum end (i.e., an end of the drum close to the side opening) disposed opposite to each other, and the driving member 123 is at least partially accommodated in the inner drum end. This embodiment is conducive to improving the compactness of the cleaning robot 100 by providing the driving member 123, and the driving member 123 is at least partially accommodated in the inner drum end.

[0056] In some embodiments of the present application, the drum module 120 further includes a driving member 123, the supporting inner core 122 includes a relatively arranged supporting inner core inner end (i.e., the end of the supporting inner core away from the side opening) and a supporting inner core outer end (i.e., the end of the supporting inner core close to the side opening), and the drum 121 includes a relatively arranged drum inner end and a drum outer end, the supporting inner core inner end is drivingly connected to the driving member 123, and the supporting inner core outer end is drivingly connected to the drum outer end. During operation, the driving member 123 drives the supporting inner core 122 to rotate, and the supporting inner core 122 drives the drum 121 to rotate so as to clean the surface to be cleaned. This embodiment is conducive to improving the compactness and stability of the cleaning robot 100 by providing a driving member 123, and the supporting inner core inner end is drivingly connected to the driving member 123, and the supporting inner core outer end is drivingly connected to the drum outer end.
