[0046] Figure 1 This is a schematic diagram of the structure of the components of the cleaning robot in an unlocked state shown in an embodiment of the present application. Figure 2 for Figure 1 A cutaway view of a cleaning robot is shown, Figure 3 for Figure 2 Another cutaway view of the cleaning robot is shown, wherein the cleaning robot is in a locked state.

[0047] First, please refer to Figures 1 to 3The cleaning robot comprises: a cleaning robot body 10, an accessory container 20 and a locking mechanism 30; the cleaning robot body 10 has an installation space 10b with an open side; the locking mechanism 30 is arranged on the cleaning robot body 10 or the accessory container 20; the locking mechanism 30 has a locked state and an unlocked state. In the locked state, the accessory container 20 is embedded in the installation space 10b, and in the unlocked state, the accessory container 20 can be detached from the cleaning robot body 10 from the open position.

[0048] When the cleaning robot is performing floor cleaning work, the locking mechanism 30 is in a locked state, and the cleaning robot body 10 can collect garbage such as dust or debris on the floor into the accessory container 20. After the garbage in the accessory container 20 accumulates to a certain amount, the locking state can be switched to an unlocked state by operating the locking mechanism 30, and the accessory container 20 can be disassembled from the cleaning robot body 10 to facilitate the cleaning of the garbage in the accessory container 20.

[0049] In order to make those skilled in the art better understand the technical solution provided by the embodiments of the present application, Figures 1 to 9 Exemplary embodiments of the cleaning robot of the present application are described in detail.

[0050] For the convenience of description, each embodiment of the present application takes the cleaning robot as an example of a sweeping and mopping robot. It is understandable that the cleaning robot can also be a sweeping robot, a mopping robot, a window cleaning robot, a handheld vacuum cleaner, or a hand-pushed cleaning machine, etc., in addition to the sweeping and mopping robot, and is not specifically limited here.

[0051] In addition, the shape of the cleaning robot is not limited to Figure 1 The circle shown may also be a square, an ellipse, a triangle or a polygon, etc., which is not specifically limited here.

[0052] For the cleaning robot body 10, an accommodating space (not shown) is defined inside the cleaning robot body 10, and electrical components such as a vacuum pump, a circuit board, a ground detection sensor, a collision detection sensor and a wall sensor can be arranged in the accommodating space.

[0053] In addition, the cleaning robot body 10 defines an installation space 10b with an open side as mentioned above and a recessed space 10c connected to the installation space 10b. The installation space 10b is used to accommodate a container body 21 of an accessory container 20 to be described in detail below, and the recessed space 10c is used to accommodate a protrusion 22 of the accessory container 20 to be described in detail below.

[0054] Figure 4 for Figure 1 The structural exploded diagram of the cleaning robot is shown in Figure 4In some embodiments, the cleaning robot body 10 includes: a shell assembly 11, a walking mechanism and a cleaning assembly. The shell assembly 11 can serve as a supporting structure for the walking mechanism, the cleaning assembly and the aforementioned electrical components to provide protection for various functional components inside the cleaning robot. The walking mechanism can be designed to autonomously plan a path on the ground, or it can be designed to move on the ground in response to remote control commands to assist in completing the floor cleaning of the cleaning robot. The cleaning assembly can effectively clean up dust, debris and other garbage on the ground, improving cleaning efficiency and cleanliness.

[0055] Please combine Figure 5 See also Figure 2 or Figure 3 In some embodiments, the housing assembly 11 has a top wall 111 , a bottom wall 112 , a first peripheral wall 113 , a second peripheral wall 114 and a cavity wall 115 .

[0056] The top wall 111 is substantially in the shape of a complete circular plate.

[0057] The bottom wall 112 is roughly C-shaped and has a U-shaped notch. The portion of the bottom wall 112 near the U-shaped notch is recessed toward the top wall 111 to form a cavity wall 115. The cavity wall 115 encloses a roller brush cavity 115a with an open bottom. The roller brush cavity 115a can be used to install a roller brush 131 of a cleaning component to be described below. The cavity wall 115 is also provided with a sewage suction port 1151 connected to the bottom opening.

[0058] The first peripheral wall 113 includes a first peripheral wall body 1131 and two oblique side walls 1132. The first peripheral wall body 1131 is disposed at the U-shaped notch and is connected to the cavity wall 115 and the top wall 111. The two oblique side walls 1132 are located at opposite ends of the first peripheral wall body 1131. One end of the first peripheral wall body 1131 is connected to the second peripheral wall 114 and the bottom wall 112 through one oblique side wall 1132, and the other end of the first peripheral wall body 1131 is connected to the second peripheral wall 114 and the bottom wall 112 through another oblique side wall 1132. The first peripheral wall body 1131 is provided with an air outlet 1133, which is connected to the external environment.

[0059] The second peripheral wall 114 surrounds and connects to the peripheral edge of the top wall 111 and the peripheral edge of the bottom wall 112 .

[0060] Part of the top wall 111, the bottom wall 112, the cavity wall 115, the first peripheral wall 113 and the second peripheral wall 114 together enclose the aforementioned installation space 10b that gradually expands from the inside of the accommodating space to the outside of the cleaning robot. The remaining part of the top wall 111, the cavity wall 115 and the first peripheral wall 113 together enclose the aforementioned installation space 10b with one side opening and the aforementioned recessed space 10c, wherein the recessed space 10c is closer to the accommodating space than the opening.

[0061] Furthermore, the connection between one end of the first peripheral wall body 1131 and one inclined side wall 1132 is a smooth transition. The connection between the other end of the first peripheral wall 113 and the other inclined side wall 1132 is a smooth transition.

[0062] Continue as Figure 4 As shown, in some embodiments, the housing assembly 11 includes a bottom shell 101, an upper cover assembly 102 and a front collision assembly 103. The upper cover assembly 102 and the front collision assembly 103 can be detachably mounted on the bottom shell 101, and the three together define the aforementioned accommodating space, the aforementioned installation space 10b and the aforementioned recessed space 10c. Among them, the bottom shell 101 includes a bottom wall 112, a cavity wall 115 and the remaining part of the second peripheral wall 114. The upper cover assembly 102 includes a top wall 111 and a part of the first peripheral wall 113. The front collision assembly includes a second peripheral wall 114.

[0063] It is understandable that the structure of the housing assembly 11 can be adaptively adjusted according to actual use requirements and is not limited to the above-mentioned form. For example, in other embodiments, the housing assembly 11 can be an integrally formed structure or a structure with left and right separate arrangements. In addition, the embodiments of the present application do not specifically limit the material or shape of the housing assembly 11. As an example, the housing assembly 11 can be made of plastic.

[0064] In addition, the installation space 10b is not limited to the aforementioned shape of gradually expanding from the accommodating space to the outside of the cleaning robot. Figure 5 The direction shown is inclined, or it may not be inclined, in which case the distance between the two side walls of the installation space 10b from the inside to the outside is roughly the same.

[0065] Please combine Figure 4 See also Figure 2 , Figure 3 and Figure 5 In any of the accompanying drawings, in some embodiments, the walking mechanism is installed on the bottom wall 112. The walking mechanism includes two driving wheels 121, at least one universal wheel 122, and a driving motor 123 for driving the driving wheels 121 to rotate. The two driving wheels 121 and the universal wheel 122 at least partially protrude from the bottom wall 112. For example, under the weight of the cleaning robot itself, the two wheels can be partially hidden in the accommodating space. Of course, the walking mechanism can also include any one of a triangular track wheel, a Mecanum wheel, etc.

[0066] Please continue to see Figure 4 In some embodiments, the cleaning assembly is detachably connected to the bottom wall 112. The cleaning assembly includes at least one rolling brush 131, which is disposed in the rolling brush cavity 115a and can rotate around an axis relative to the axis of the rolling brush 131 itself.

[0067] In addition, a fan is installed inside the accommodating space, the suction end of the fan is connected to the air outlet 1133, and the discharge end of the fan is connected to each through hole of the second peripheral wall 114. When the cleaning robot is in working state, the roller brush 131 rotates to stir up dust and garbage on the ground, and the suction force generated by the fan is used to suck the dust and debris from the open mouth of the roller brush cavity 115a into the dust storage cavity of the accessory container 20, and each through hole can synchronously discharge the air in the dust storage cavity.

[0068] The accessory container 20 includes a container body 21 and a convex portion 22 protruding outward from one side of the container body 21. At least part of the space of the container body 21 is a dirt collection space (not shown), and the container body is provided with a dirt inlet 2111 connected to the dirt collection space. In the locked state, the container body 21 can be embedded in the installation space 10b from one side of the installation space 10b along the travel direction X of the cleaning robot, and the convex portion 22 is accommodated in the recessed space 10c, and the dirt suction port 1151 is connected to the dirt inlet 2111.

[0069] For ease of description, each embodiment of the present application takes the accessory container 20 as an example. Figures 1 to 9 The dust box and water tank assembly shown is used as an example. The container body 21 can be a dust box and water tank assembly, and the protrusion 22 can be a pivoting portion on the dust box and water tank assembly. The aforementioned dirt collection space can collect dust or debris and other garbage. The dirt inlet 2111 on the container body 21 can be used as a dust inlet, and the corresponding dirt suction port 1151 on the cavity wall 115 can be used as a dust suction port. It can be understood that the accessory container 20 can also be a separate dust box assembly, a separate water tank assembly, or other mopping and wiping assemblies other than the dust box and water tank assembly. When the accessory container 20 is a separate dust box assembly, the dirt collection space of the container body can still collect dust or debris and other garbage; when the accessory container 20 is a separate water tank assembly, the dirt collection space of the container body 21 can collect sewage generated during cleaning.

[0070] like Figures 1 to 4 As shown, the shape of the dust box and water tank assembly is roughly adapted to the shape of the installation space 10b, and the aforementioned dirt collection space, as well as the dirt inlet 2111 and the air outlet 2112 connected to the dirt collection space are defined therein. When the dust box and water tank assembly is locked to the cleaning robot body 10, the dirt inlet 2111 can be connected to the dirt suction port 1151, so that the dust and debris cleaned by the cleaning assembly are collected into the dust storage chamber.

[0071] It is understandable that the dust box and water tank assembly is not limited to the specific structure of the dust box and water tank assembly described above. Fig. 9 As shown, in some alternative embodiments, in order to increase the volume of the dust box water tank assembly, the side of the dust box water tank assembly away from the protrusion is arranged beyond the top wall 111 along a direction parallel to the travel direction X of the cleaning robot.

[0072] The locking mechanism 30 is disposed on a side of the container body 21 away from the protrusion 22. The locking mechanism 30 includes a locking member 31 and a reset member (not shown). The locking member 31 is disposed on the container body 21. One end of the reset member abuts against the locking member 31, and the other end abuts against the container body 21, so that the locking member 31 can reciprocate on the container body 21. The locking member 31 at least partially protrudes from the container body 21 and is engaged with the top wall 111. As an example, the reset member can be a spring.

[0073] For ease of description, the following embodiments of the present application are all illustrated by taking the locking mechanism 30 as being disposed on the dust box water tank assembly.

[0074] Please combine Figure 8 See also Figure 1 In some embodiments, a mounting groove 21b is provided on the side of the dust box and water tank assembly that is away from the traveling direction X of the cleaning robot, a locking member 31 is provided in the mounting groove 21b and can slide up and down along the mounting groove 21b, one end of the reset member abuts against the bottom wall 112 of the mounting groove 21b, and the other end abuts against the locking member 31. A through hole is provided at the top of the mounting groove 21b, and a portion of the locking member 31 passes through the through hole and is clamped on the top wall 111. By pressing the locking piece 31, the locking piece 31 is made to reciprocate on the container body 21. When the locking piece 31 moves downward along the mounting groove 21b, the portion of the locking piece 31 protruding from the top of the mounting groove 21b will be separated from the top wall 111 and sunk into the mounting groove 21b, so that the accessory container 20 can be removed from the mounting space 10b. At this time, the locking mechanism 30 is in an unlocked state; and when the locking piece 31 is pressed so that the locking piece 31 is completely sunk into the mounting groove 21b, and then the accessory container 20 is inserted into the mounting space 10b, and then the locking piece 31 is released, the reset piece will lift the locking piece 31 so that the top of the locking piece 31 passes through the through hole and is connected to the top wall 111, so as to lock the accessory container 20 in the mounting space 10b. At this time, the locking mechanism 30 is in an unlocked state.

[0075] Of course, the position of the locking mechanism 30 is not limited to being arranged on the side of the container body 21 away from the protrusion 22. Its position can be adaptively adjusted according to the structure of the actual accessory container 20. As long as the locking mechanism 30 is in a locked state, it can restrict the container body 21 to the installation space 10b and the protrusion 22 to the recessed space 10c.

[0076] like Figure 2 , Figure 3 as well as Figure 5As shown, in some further embodiments, the surface of the top wall 111 facing the installation space 10b or the surface of the top wall 111 facing the recessed space 10c is convexly provided with an elastic protrusion 14. When the locking mechanism 30 is in a locked state, the elastic protrusion 14 can abut against the top wall 111 of the container body 21 to apply a force to the protrusion 22, so that the protrusion 22 always abuts against the cavity wall 115.

[0077] Compared with the cleaning robot of the related art, the cleaning robot involved in the present application is additionally provided with an elastic protrusion 14 on the top wall 111 of the installation space 10b. When the locking mechanism 30 is in the locked state, the elastic protrusion 14 continuously applies a force to the convex portion 22, so that the convex portion 22 can always abut against the cavity wall 115. Under the joint action of the locking mechanism 30 and the elastic protrusion 14, the accessory container 20 can be stably installed in the installation space 10b, thereby improving the shaking of the accessory container 20 caused by the vibration when the cleaning robot is running, thereby improving the operating efficiency of the cleaning robot.

[0078] Furthermore, the elastic protrusion 14 is convexly disposed on the surface of the top wall 111 facing the recessed space 10c, which is substantially corresponding to the convex portion 22. In this way, the convex portion 22 is subjected to a greater force, so that the accessory container 20 can be more stably installed in the installation space 10b.

[0079] Continue as Figures 2 to 5 as well as Figure 6 As shown, in order to enhance the connection stability between the accessory container 20 and the cleaning robot body 10, in some embodiments, the cleaning robot body 10 further includes an abutment portion 15, which is convexly disposed on the surface of the cavity wall 115 facing the recessed space 10c. When the locking mechanism 30 is in a locked state, the elastic protrusion 14 can abut against the container body 21 to apply a force to the protrusion 22, so that the protrusion 22 abuts against the abutment portion 15.

[0080] Furthermore, the end surface of the abutment portion 15 away from the cavity wall 115 is a flat surface. When the locking mechanism 30 is in a locked state, the elastic protrusion 14 can abut against the container body 21 to apply a force to the protrusion 22 so that the protrusion 22 abuts against the flat surface of the abutment portion 15.

[0081] Please combine Figure 7 and Figure 5 See also Figure 3 or Figure 2, also in order to enhance the connection stability between the accessory container 20 and the cleaning robot body 10, in some embodiments, the container body 21 includes a long side wall 211, a first short side wall 212 and a second short side wall 213, the first short side wall 212 and the second short side wall 213 are arranged oppositely, and the long side wall 211 is located on one side of the accessory container 20 and is connected to the first short side wall 212 and the second short side wall 213 respectively. The long side wall 211, the first short side wall 212, and the second short side wall 213 form a long rectangular area. Among them, the rotating shaft portion is arranged at the bottom of the long side wall 211, and the exhaust port 2112 is arranged in the middle of the long side wall 211. It should be noted that the long side wall 211 mentioned here specifically refers to a side wall longer than the short side wall, and the short side wall specifically refers to a side wall shorter than the long side wall 211.

[0082] Specifically, the number of the elastic protrusion 14 , the convex portion 22 , the concave space 10 c and the abutting portion 15 are all two.

[0083] One recessed space 10 c is located on one side of the first peripheral wall body 1131 close to one inclined side wall 1132 , and the other recessed space 10 c is located on one side of the first peripheral wall body 1131 close to the other inclined side wall 1132 .
