[0021] See also Figures 1 to 3 The present application also proposes a robot system 1000 , which includes a cleaning robot 200 and a maintenance base station 100 .

[0022] The maintenance base station 100 includes a dust collecting device 10 and a dust collecting assembly 20. The dust collecting device 10 is provided with a dust collecting chamber 11 and a dust inlet channel 12 connected to the dust collecting chamber 11, and a dust extraction system 13 connected to the dust collecting chamber 11. The dust collecting assembly 20 includes a filter bag 21 and a handle bracket 22 connected to the filter bag 21. The filter bag 21 is detachably installed in the dust collecting chamber 11 along with the handle bracket 22. The handle bracket 22 is provided with a first opening 23 and a dust shield 24 corresponding to the first opening 23. The first opening 23 is installed in the dust collecting chamber 11 along with the handle bracket 22 and is aligned with the dust inlet channel 12. The dust shield 24 is used to prevent dust and / or debris from escaping through the first opening 23 when the first opening 23 is separated from the dust inlet channel 12.

[0023] The cleaning robot 200 includes a dust collecting container 30 and a dust exhaust part 40 connected to the dust collecting container 30. The dust exhaust part 40 is used to connect with the dust inlet channel 12 of the dust collecting device 10 to allow dust and / or debris to be transferred from the dust collecting container 30 to the filter bag 21 under the suction force of the dust extraction system 13.

[0024] It is understandable that the cleaning robot 200 can be any one of a sweeping robot, a sweeping and mopping robot, a driving cleaning robot, a handheld cleaning robot or a mopping robot.

[0025] The cleaning robot 200 may include a chassis and an upper cover assembly. The upper cover assembly is detachably mounted on the chassis to protect the various functional components inside the cleaning robot from damage caused by violent impacts or accidentally dripping liquids during use; the chassis and / or the upper cover assembly are used to carry and support the various functional components. The surface of the upper cover assembly facing away from the chassis forms an appearance surface, which can enhance the overall appearance of the cleaning robot. Buttons can be provided on the appearance surface to facilitate the user to operate the cleaning robot through buttons. The installation cavity is formed between the chassis and the upper cover assembly, and the installation cavity is used to provide arrangement space for the internal components of the cleaning robot. The cleaning robot can arrange a vacuum pump, a circuit board, a ground detection sensor, a collision detection sensor, a wall sensor, etc. in the installation cavity.

[0026] The cleaning robot 200 includes a running mechanism mounted on the chassis, the running mechanism including two running wheels, at least one universal wheel, and a motor for driving the wheels to rotate, the two running wheels and the at least one universal wheel at least partially protruding from the bottom of the chassis. For example, under the weight of the cleaning robot, the two running wheels can be partially hidden in the chassis. In an optional embodiment, the running mechanism can also include any one of triangular track wheels, Mecanum wheels, etc. The running mechanism may also not include the at least one universal wheel.

[0027] The cleaning robot 200 may include at least one middle sweeping brush, which may be arranged in a receiving groove opened at the bottom of the chassis. A dust suction port is opened in the receiving groove, and the dust suction port is connected to the dust box assembly and the dust suction fan, so that when the middle sweeping brush rotates, the dust and garbage on the ground are stirred up, and the dust suction fan is used to generate suction force to suck the dust and garbage from the dust suction port into the dust box assembly.

[0028] The cleaning robot 200 can be designed to autonomously plan a path on the ground, or can be designed to move on the ground in response to remote control commands. The cleaning robot can navigate by using one or a combination of a gyroscope, an accelerometer, a camera, a GPS positioning system, and / or a laser radar. For example, the cleaning robot 200 can be provided with a laser radar protruding from the top surface, and the laser radar can be used to scan the surrounding environment and collect obstacle data. An environmental map can be established based on the obstacle data, and real-time positioning can be performed based on the environmental map to facilitate planning of the cleaning path.

[0029] It can be understood that the cleaning robot 200 can autonomously navigate to the dust collection device 100, so that the cleaning robot 200 is docked with the dust collection device 100, and the dust exhaust port of the cleaning robot 200 is docked and connected with the dust collection port of the dust collection device 100, so that the dust collection device 100 can suck the garbage in the cleaning robot 200 through the above-mentioned dust collection port and dust exhaust port, thereby realizing the recycling of the garbage in the cleaning robot 200 to the dust collection device 100.

[0030] In the technical solution of the present application, the filter bag body 21 is detachably installed in the dust collecting chamber 11 along with the handle bracket 22, and the handle bracket 22 is provided with a first opening 23 and a dust shield 24 corresponding to the first opening 23. The first opening 23 is installed in the dust collecting chamber 11 along with the handle bracket 22 and is aligned with the dust inlet channel 12. The dust shield 24 is used to prevent dust and / or debris from escaping through the first opening 23 when the first opening 23 is separated from the dust inlet channel 12. This can solve the technical problem that when the dust collecting component 20 is removed from the dust collecting device 10 to replace a new dust collecting component 20, dust and debris inside the dust collecting component 20 easily escape from the bag mouth, thereby preventing pollution of the environment and the user's hands, and improving the user experience.

[0031] In this embodiment, the dust collecting device 10 includes a base body 14 and a cover body 15. The base body 14 is the main part of the dust collecting device 10, and the base body 14 is provided with a dust collecting port 141, a dust inlet channel 12, an inner cavity and an exhaust channel. The dust collecting port 141 is arranged on the outside of the base body 14, and the dust collecting port 141 is used to dock with the dust exhaust port of the cleaning robot 200. The inner cavity is used to accommodate the dust collecting component 20, and the inner cavity has an open end. The dust collecting component 20 is detachably installed in the inner cavity of the base body 14 through the open end. The cover body 15 is rotatably connected to the base body 14 to cover or open the open end of the inner cavity. One end of the dust inlet channel 12 is connected to the dust collecting port 141, and the other end is connected to the inner cavity. One end of the exhaust channel is connected to the dust collecting cavity, and the other end is connected to the atmosphere. The dust collection assembly 20 is installed in the inner cavity and can be connected to the dust inlet channel 12 and the exhaust channel. The dust extraction fan is located in the exhaust channel and is used to drive the gas flow. The dust extraction fan can drive the gas in the inner cavity to flow to the exhaust channel to be discharged to the outside, thereby generating negative pressure in the dust collection assembly 20 and the dust inlet channel 12. By sucking the garbage in the cleaning robot 200 into the dust collection assembly 20 under the action of negative pressure, dust collection is achieved. The inner cavity forms the dust collection chamber 11, and the exhaust channel and the dust extraction fan constitute the dust extraction system 13.

[0032] In this embodiment, the specific shape of the handle bracket 22 can be various. For example, the handle bracket 22 can be any one of sheet-shaped, plate-shaped, arc-shaped, T-shaped or special-shaped. Those skilled in the art can set it according to actual needs and no specific limitation is made here.

[0033] The handle bracket 22 is detachably mounted in the dust collecting chamber 11. The handle bracket 22 can be mounted in the dust collecting chamber 11 by means of a plug-in fit with a slot, a snap connection, a lock structure or a screw connection.

[0034] The material of the filter bag 21 can be plastic, paper or a composite material, which is not specifically limited here, and those skilled in the art can set it according to actual needs.

[0035] When the dust extraction fan is working, the dust inlet channel 12 can introduce airflow into the filter bag 21 under the action of vacuum negative pressure, and then the airflow can pass through the filter bag 21 and enter the exhaust channel and be discharged, wherein the filter bag 21 can play a filtering role and intercept dust debris carried in the airflow.

[0036] See also Figures 2 to 3 In the first embodiment, the dust shield 24 may be a movable structure, that is, the dust shield 24 may be movable relative to the handle bracket 22 (for example, the dust shield 24 is rotatably connected to the handle bracket 22), and the dust shield 24 may be switched to a position covering the first opening 23, or switched to a position opening the first opening 23. The dust shield 24 may open or cover the first opening 23. The dust shield 24 may be driven by the dust inlet channel 12 or the dust extraction system 13 to open the first opening 23, so as to allow dust and / or debris to enter the filter bag 21 through the dust inlet channel 12 and the first opening 23 in sequence under the suction force of the dust extraction system 13. The dust shield 24 may naturally cover the first opening 23 after the driving force is released, so as to prevent dust and / or debris from escaping through the first opening 23 when the first opening 23 is separated from the dust inlet channel 12.

[0037] See also Figure 2 、 Figure 3 and Figure 4In a first embodiment, the dust shield 24 opens the first opening 23 under the suction drive of the dust extraction system 13; or, one end of the dust inlet channel 12 extends into the first opening 23 and mechanically drives the dust shield 24 to open the first opening 23. The advantage of this is that by mechanically driving the dust shield 24 to move relative to the handle bracket 22, one end of the dust inlet channel 12 can push the dust shield 24 to move to a preset maximum opening position, and one end of the dust inlet channel 12 can maintain contact with the dust shield 24 to provide support and stabilization for the dust shield 24, so that the dust shield 24 is stably maintained in the preset maximum opening position, thereby preventing the dust shield 24 from shaking with the dust-laden airflow during the dust collection process, and further preventing the dust shield 24 from excessive shaking and detaching from the handle bracket 22. Among them, the dust shield 24 is in the shape of a sheet. When the dust shield 24 moves to the preset maximum opening position, the dust shield 24 is set at an angle to the dust outlet direction of the dust inlet channel 12, and the dust outlet direction of the dust inlet channel 12 is aligned with the dust shield 24, so that the dust-laden airflow coming out of the dust inlet channel 12 first hits the dust shield 24. The dust shield 24 can play a buffering and decelerating role, so that the dust debris in the airflow is decelerated and falls to the bottom of the filter bag 21.

[0038] See also Figure 5 In the second embodiment, the dust shield 24 can be a fixed structure, that is, the dust shield 24 can be fixedly connected to the handle bracket 22 by screw connection, glue bonding, integral injection molding, snap connection or thermal welding. The dust shield 24 is located in the filter bag body 21, and the dust shield 24 is arranged opposite to the first opening 23. A lateral dust inlet 60 is formed between the dust shield 24 and the inner side wall of the handle bracket 22. Dust and / or debris entering from the first opening 23 can enter the filter bag body 21 through the lateral dust inlet 60. The dust shield 24 is arranged opposite to the first opening 23, and the dust shield 24 can prevent dust and / or debris from leaking from the direction opposite to the first opening 23. In some embodiments, a transition guide surface 70 is provided in the area of ​​the dust shield 24 facing the first opening 23. The transition guide surface 70 is a smooth curved surface, a flat surface, or a bent surface. The transition guide surface 70 is connected between the first opening 23 and the lateral dust inlet 60. The transition guide surface 70 is used to change the dust intake direction and to smoothly guide the dust and / or debris entering from the first opening 23 to the lateral dust inlet 60, thereby avoiding the situation where dust and / or debris are retained in the dust shield 24.

[0039] Please continue reading Figure 6 and Figure 7For the first embodiment, in some embodiments, the dust collecting assembly 20 includes a baffle 25, which is movably connected to the handle bracket 22, and the baffle 25 can be flipped relative to the handle bracket 22 to cover or open the first opening 23, and the baffle 25 forms the dust blocking portion 24.

[0040] The blocking piece 25 can be movably connected to the handle bracket 22 by means of a hook, a rotating shaft connection, a magic tape, a sticky connection or an elastic part connection.

[0041] The blocking piece 25 can be any one of a plastic blocking piece, a rubber blocking piece, a silicone blocking piece or a metal blocking piece.

[0042] In this embodiment, the handle bracket 22 is provided with at least one hook 221, which is positioned adjacent to the first opening 23. The blocking piece 25 is provided with at least one positioning hole, and the at least one hook 221 is respectively hooked into the at least one positioning hole. The blocking piece 25 can be rotated around the at least one hook 221. The number of the hooks 221 can be one, two, three, or more. The number of the positioning holes is the same as the number of the hooks 221. The dust shield 24 can return to a position covering the first opening 23 under its own weight.

[0043] In other embodiments, the handle bracket 22 may also be provided with a rotating shaft portion, and the handle bracket 22 is rotatably connected to the handle bracket 22 via the rotating shaft portion. In addition, the dust collection assembly 20 includes an elastic member that elastically connects the rotating shaft portion and the handle bracket 22. The elastic member may be an elastic structure such as a rectangular spring, a torsion spring, a rubber member, or a silicone member. The elastic member can help the dust shield 24 return to a position covering the first opening 23.

[0044] See also Figure 8 Furthermore, the dust shield 24 is provided with a connecting side portion 251 and a free side portion 252 arranged relative to the connecting side portion 251. The dust shield 24 is movably connected to the handle bracket 22 through the connecting side portion 251. The dust shield 24 is also provided with a first locking portion 253 on the free side portion 252. The handle bracket 22 is provided with a second locking portion 254 arranged corresponding to the first locking portion 253. When the dust shield 24 covers the first opening 23, the second locking portion 254 is fixed to the first locking portion 253 by magnetism.

[0045] In this embodiment, the connecting side portion 251 and the free side portion 252 are respectively located on opposite sides of the blocking piece 25. The blocking piece 25 is movably connected to the handle bracket 22 via the connecting side portion 251. As previously mentioned, the blocking piece 25 can be movably connected to the handle bracket 22 by means of a hook, a rotating shaft connection, a Velcro connection, an adhesive connection, or an elastic connection, which will not be described in detail here.

[0046] Among them, the first locking part 253 can be a magnetic part or a metal part (a metal material that can be attracted by a magnet), and the second locking part 254 can be a magnetic part, so that the second locking part 254 is adsorbed and fixed to the first locking part 253 by magnetism, so that after the user takes out the dust collecting component 20 from the dust collecting chamber 11, the dust shield 24 can remain in the position of covering the first opening 23, which can prevent the dust shield 24 from shaking and opening the first opening 23 to cause garbage leakage.

[0047] Please continue reading Figure 9 , with respect to the first embodiment, in other embodiments, the handle bracket 22 includes a bracket body 201 connected to the filter bag body 21, and a flexible baffle 202 integrally formed with the bracket body 201, the bracket body 201 is provided with the first opening 23, the flexible baffle 202 can be driven by the dust inlet channel 12 or the dust extraction system 13 to bend and deform to open the first opening 23, and the flexible baffle 202 naturally covers the first opening 23 under the action of its own elastic force after the drive is withdrawn, and the flexible baffle 202 forms the dust blocking portion 24.

[0048] The flexible baffle 202 can be any one of a plastic baffle, a rubber baffle, a silicone baffle, or a metal baffle. Since the flexible baffle 202 is integrally formed with the bracket body 201, for example, the flexible baffle 202 and the bracket body 201 are both made of plastic, and the flexible baffle 202 and the bracket body 201 are integrally injection molded, the number of disassembled parts of the dust collection assembly 20 and the assembly process can be reduced, thereby simplifying the manufacturing process and reducing manufacturing costs.

[0049] In the technical solution of the present application, the filter bag body 21 is detachably installed in the dust collecting chamber 11 along with the handle bracket 22, and the handle bracket 22 is provided with a first opening 23 and a dust shield 24 corresponding to the first opening 23. The first opening 23 is installed in the dust collecting chamber 11 along with the handle bracket 22 and is aligned with the dust inlet channel 12. The dust shield 24 is used to prevent dust and / or debris from escaping through the first opening 23 when the first opening 23 is separated from the dust inlet channel 12. This can solve the technical problem that when the dust collecting component 20 is removed from the dust collecting device 10 to replace a new dust collecting component 20, dust and debris inside the dust collecting component 20 easily escape from the bag mouth, thereby preventing pollution of the environment and the user's hands, and improving the user experience.
