[0016] Garbage: Unclaimed solid waste such as dust, particles, and debris that needs to be cleaned up; Waste separation: separating waste from the airflow; Wastewater: Wastewater containing dirt, stains, or garbage; Wastewater separation: separating wastewater from airflow. Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] refer to Figures 1 to 3 A cleaning robot with a multi-cone separation structure. A cleaning robot is an intelligent robotic device that can perform cleaning tasks automatically or semi-automatically.

[0019] The cleaning robot includes: The chassis 200 is equipped with a roller brush 210, a dust suction port 220, a wastewater box 240 and a blower 230; The roller brush 210 is connected to a corresponding motor drive for cleaning surfaces such as the ground; the suction port 220 is used to suck up garbage and / or sewage, and the suction port 220 can be located on the rear side of the roller brush 210; the fan 230 is used to generate airflow; and the sewage box 240 is used to store garbage and / or sewage.

[0020] And a separation module 100, located above the rear side of the chassis 200; the separation module 100 is used to separate garbage and / or sewage from the airflow, and can achieve garbage separation and sewage separation.

[0021] refer to Figure 4 and Figure 11 The separation module 100 includes a primary separation chamber 10, a secondary separation chamber 20, a spiral air duct 11, and an exhaust pipe 30. The primary separation chamber 10 is vertically arranged, and the spiral air duct 11 extends downward spirally. The spiral air duct 11 includes an air inlet 111 and an air outlet 112. The air inlet 111 of the spiral air duct 11 can be connected to the dust suction port 220 through the first pipe 270, and the air outlet 112 of the spiral air duct 11 is connected to the top of the primary separation chamber 10. Multiple secondary separation chambers 20 are evenly arranged, and the multiple secondary separation chambers 20 are located in the middle of the interior of the primary separation chamber 10; The tops of the multiple secondary separation chambers 20 are respectively connected to the primary separation chamber 10 through multiple first channels 22; and the first channels 22 are higher than the air outlet 112; The tops of the multiple secondary separation chambers 20 are connected to the exhaust pipe 30; the exhaust pipe 30 can be connected to the fan 230 through the second pipe 280; The bottom end of the primary separation chamber 10 is connected to the sewage box 240; for example, the bottom end of the primary separation chamber 10 has an open structure, which has a through hole, notch, open mouth and other structures. The bottom end of the secondary separation chamber 20 is connected to the bottom cover 7. For example, the bottom end of the secondary separation chamber 20 is an open structure, so that it can be connected to the bottom cover 7; for example, the bottom end of the bottom cover 7 is a closed structure, and the bottom cover 7 is at least covered upward on the bottom end of the secondary separation chamber 20.

[0022] The air inlet 111 of the spiral duct 11 is connected to the dust suction port 220 of the cleaning robot; the exhaust pipe 30 is connected to the fan 230, which is used to generate airflow; the sewage box 240 is located below the primary separation cylinder 1, and the bottom end of the primary separation chamber 10 can communicate with the sewage box 240, which is used to collect garbage and sewage.

[0023] Garbage and / or sewage are drawn into the dust inlet by the airflow and flow to the spiral duct 11. Under the action of the spiral duct 11, a downward spiral airflow is formed. The spiral airflow flows in a spiral or circular motion within the primary separation chamber 10. Garbage and / or sewage move outward under the action of centrifugal force, which causes the garbage or sewage to move away from the center of the spiral airflow. Under the action of the self-weight of the garbage and / or sewage and the downward inertial component of the spiral motion, the garbage and / or sewage gradually move downward or settle and move to the sewage box 240, thus achieving primary separation of garbage and / or sewage.

[0024] Then, the central airflow of the spiral airflow flows along the first channel 22 to the secondary separation chamber 20. The airflow performs circular or spiral motion in the secondary separation chamber 20. The garbage and / or sewage move outward again under the action of centrifugal force, and under the action of the garbage and / or sewage's own weight, the garbage and / or sewage gradually move downward or settle, and move to or settle to the bottom of the bottom cover 7, thus realizing the secondary separation of garbage and / or sewage.

[0025] Finally, the airflow that has separated the garbage and / or sewage flows upward to the exhaust pipe 30 and is discharged to the outside.

[0026] Thus, the garbage and / or sewage undergo two centrifugal processes, achieving thorough separation from the airflow and improving the separation effect.

[0027] In addition, most or large particles of garbage and / or sewage are separated in the primary separation chamber 10, while a small portion or small particles of garbage and / or sewage located at the center of the spiral airflow are separated in the secondary separation chamber 20. Thus, the garbage and / or sewage undergo two centrifugal separation actions, achieving full separation between the garbage and / or sewage and the airflow, improving the separation effect. Furthermore, the separation module can separate not only garbage but also sewage, improving the cleaning effect; this solves the shortcoming of existing cleaning robots that can only separate garbage but cannot effectively separate sewage.

[0028] refer to Figure 6The first channel 22 is higher than the air outlet 112 of the spiral duct 11, so that when the spiral airflow reaches the primary separation chamber 10, it first moves downward in a spiral or circular motion under the action of inertia, and then flows upward to the first channel 22. This avoids the spiral airflow flowing directly to the first channel 22. After the garbage and / or sewage have been separated to a certain extent in the primary separation chamber 10, the airflow flows to the first channel 22 and then to the secondary separation chamber 20 for a second separation. Therefore, the first channel 22 is higher than the air outlet 112 of the spiral duct 11, forming a certain spatial distance, which ensures that there is a certain time sequence between the primary and secondary separation of garbage and / or sewage.

[0029] refer to Figure 6 and Figure 9 Three secondary separation chambers 20 are evenly arranged. The number of secondary separation chambers 20 corresponds one-to-one with the number of first channels 22, and the airflow flows into each secondary separation chamber 20 through the corresponding first channel 22. Having three or more secondary separation chambers 20 improves the separation effect and efficiency, and also reduces noise generated by airflow. Of course, four, five, six, seven, eight, nine, or more secondary separation chambers 20 can also be provided, thus creating multiple secondary separation chambers 20.

[0030] The first channel 22 can be in the form of an arc structure, which can form a tangential connection with the secondary separation chamber 20.

[0031] At least the bottom of the secondary separation chamber 20 gradually narrows downwards; for example, the bottom of the secondary separation chamber 20 gradually narrows downwards, or the secondary separation chamber 20 gradually narrows downwards from top to bottom. The gradually narrowing conical structure can promote the downward settling of garbage and / or sewage.

[0032] refer to Figure 7 The bottom end of the first sidewall 14 of the primary separation chamber 10 is open, meaning the bottom of the primary separation chamber 10 is open. The wastewater box 240 is located below the primary separation cylinder 1, and the bottom end of the primary separation chamber 10 is connected to the wastewater box 240. The separated waste and / or wastewater can sink downwards into the wastewater box 240.

[0033] refer to Figure 6 The bottom cover 7 is cylindrical and coaxially arranged with the primary separation cylinder 10. The bottom cover 7 can cover multiple secondary separation chambers 20 upwards. The bottom cover 7 is not only used to collect garbage and / or sewage, but also to isolate the secondary separation chambers 20 from the primary separation chamber 10 and to create a stable space that facilitates the movement of spiral airflow in the primary separation chamber 10. At least the bottom of the bottom cover 7 has a gradually narrowing structure, which facilitates the faster settling of garbage and / or sewage to the bottom.

[0034] refer to Figure 6The bottom of the base cover 7 has a sealed structure, for example, achieved by a cap 72. The cap 72 can be connected to the bottom of the base cover 7 via a snap, screw, or thread structure, thus forming a sealed structure. Since the amount of waste and / or sewage flowing into the secondary separation chamber 20 is relatively small, the separated waste and / or sewage can settle to the bottom of the base cover 7. Furthermore, the sealed structure helps reduce airflow from the bottom of the base cover 7 into the secondary separation chamber 20, allowing multiple secondary separation chambers 20 to be located in relatively independent spaces, reducing external influences. Moreover, the cap 72 is a detachable structure, facilitating the cleaning of waste and / or sewage inside the base cover 7.

[0035] refer to Figure 5 and Figure 6 The separation module 100 is provided with connecting pipes 12; the number of connecting pipes 12 corresponds one-to-one with the number of secondary separation chambers 20, each connecting pipe 12 is coaxially arranged with the corresponding secondary separation chamber 20, and the top of each secondary separation chamber 20 is connected to the corresponding connecting pipe 12.

[0036] The top end of the connecting pipe 12 is connected to the exhaust pipe 30, and the bottom end of the connecting pipe 12 is connected to the top of the secondary separation chamber 20; the bottom end of the connecting pipe 12 is lower than the first channel 22.

[0037] The top of the primary separation cylinder 1 is provided with an exhaust chamber 13, which is located above the secondary separation chamber 20; The top end of the connecting pipe 12 is connected to the exhaust chamber 13, and the exhaust chamber 13 is connected to the exhaust pipe 30 of the top cover 3.

[0038] Thus, the airflow after separating garbage and / or sewage flows through the connecting pipe 12 to the exhaust chamber 13, and then flows to the outside through the exhaust pipe 30; wherein, the bottom end of the connecting pipe 12 is lower than the first channel 22, which causes the airflow to undergo a certain circular or spiral motion before it can flow upward to the exhaust chamber 13, thereby improving the separation effect of garbage and / or sewage.

[0039] refer to Figure 6 The ratio of the diameter D1 of the first sidewall 14 of the primary separation chamber 10 to the diameter D2 of the second sidewall 71 of the bottom cover 7 is between 2.0 and 3.0. This size setting ensures that the primary separation chamber 10 has sufficient space for the separation of garbage and / or sewage, and ensures that most or even all of the garbage and / or sewage can be separated from the airflow during primary separation, thus ensuring the separation effect and ensuring that a certain amount of garbage and / or sewage is separated and processed, that is, ensuring the separation efficiency.

[0040] refer to Figure 6The spiral air duct 11 extends spirally downward along the inner side of the first sidewall 14; the first sidewall 14 may be vertically arranged. Thus, the spiral airflow can flow smoothly to the primary separation chamber 10, and then perform spiral or circular motion along the first sidewall 14; the vertically arranged first sidewall 14 causes the spiral airflow to move stably with a constant spiral diameter, and garbage and / or sewage approach the first sidewall 14 under the action of centrifugal force and move downward along the first sidewall 14 to the sewage box 240.

[0041] refer to Figure 5 and Figure 6 A filter screen 5 is provided between the primary separation chamber 10 and the secondary separation chamber 20. The filter screen 5 is cylindrical. As a result, when the airflow flows from the primary separation chamber 10 to the secondary separation chamber 20, the filter screen 5 can filter or block some of the garbage and / or sewage, thereby further improving the separation effect of garbage and / or sewage.

[0042] refer to Figure 5 and Figure 6 The separation module 100 also includes a baffle 6, which is sleeved on the outer side of the bottom of the second side wall 71 of the base cover 7; A first annular groove 61 is provided above the edge of the baffle 6, and the bottom of the filter screen 5 is connected to the first annular groove 61. For example, the bottom of the filter screen 5 is inserted into the first annular groove 61 to fix the filter screen 5; the baffle 6 can reduce the downward flow of spiral airflow to the sewage box 240, and also prevent or reduce the upward flow of garbage and / or sewage in the sewage box 240 back to the primary separation chamber 10.

[0043] The edge of the baffle 6 is provided with an outward and downward extending convex edge 62, which can cause garbage and / or sewage to sink downward into the sewage box 240.

[0044] refer to Figure 5 and Figure 6 The separation module 100 includes a primary separation cylinder 1, a secondary separation component 2, and a top cover 3; The first sidewall 14 of the primary separation cylinder 1 and the second sidewall 71 of the bottom cover 7 form the primary separation chamber 10; The top of the primary separation cylinder 1 is equipped with a spiral air duct 11; The secondary separator 2 is located in the middle of the interior of the primary separator 1; for example, the primary separator 1 and the secondary separator 2 are coaxially arranged. The secondary separation component 2 includes multiple cones 21 and multiple first channels 22; the interior of the cones 21 forms a secondary separation cavity 20.

[0045] refer to Figure 5 and Figure 6 The separation module 100 also includes a first gasket 41 and a second gasket 42; The top of the primary separation cylinder 1 is provided with a first protruding ring 15, which forms an exhaust cavity 13 with the top wall of the top cover 3. A first gasket 41 is provided between the top of the first protruding ring 15 and the top cover 3 to improve the sealing of the connection.

[0046] The second gasket 42 is located between the top of the secondary separator 2 and the primary separator 1, which helps to improve the sealing of the connection.

[0047] refer to Figure 10 The top of the top cover 3 is provided with a rotatable handle 31. The handle 31 is rotatably connected to the top cover 3 via a first convex shaft 32 and a first shaft hole 33, thereby facilitating the extraction or movement of the entire separation module 100.

[0048] The top of the secondary separator 2 can be assembled into the interior of the primary separator 1 using screws, clips, or screws. The top cover 3 can be assembled to the top or above the primary separation cylinder 1 using screws, clips, or other structures; For example, the primary separator 1, the secondary separator 2, and the top cover 3 are connected and fixed by a common first screw. The top cover 3 is provided with a first stud. The primary separator 1 and the secondary separator 2 are both provided with corresponding first through holes and second through holes. The first screw passes through the two second through holes and the first through hole in sequence and is screwed to the first stud.

[0049] The bottom cover 7 can be connected to the secondary separation component 2 via a structure such as a snap fastener, a screw fastener, or a thread; The cover 72 can be assembled to the bottom of the base cover 7 by means of a snap, a screw, or a thread. For example, the cover 72 has a protruding buckle, and the base cover 7 has a buckle groove that mates with the protruding buckle.

[0050] The upper end of the filter screen 5 is fitted onto the top of the primary separation cylinder 1 or the secondary separation component 2, and the lower end is inserted into the first annular groove 61 of the baffle 6.

[0051] The baffle 6 can be assembled to the base cover 7 by means of a snap, screw or other structure; for example, the outer side of the base cover 7 is provided with a second stud, the baffle 6 is provided with a corresponding third through hole, and the second screw passes through the third through hole and is screwed to the second stud.

[0052] refer to Figures 1 to 3 The chassis 200 is provided with a slide 250, and the sewage box 240 is detachably located in the slide 250; the sewage box 240 and the slide 250 form a drawer-like structure.

[0053] The top wall of the slide 250 is provided with an assembly hole 2501, and the bottom of the separation module 100 is detachably connected to the assembly hole 2501. The assembly hole 2501 can be a stepped hole, and the bottom of the first side wall 14 of the separation module 100 can be inserted into the assembly hole 2501, and can be easily lifted and moved by the handle 31.

[0054] refer to Figures 1 to 3 The separation module 100, fan 230, and wastewater box 240 are all located behind the roller brush 210. A battery pack 260, which is elongated, is located on the front of the roller brush 210. The chassis 200 has a groove for holding the battery pack 260. Because the separation module 100, fan 230, and wastewater box 240 are all located behind the chassis 200, the weight of the chassis 200 is uneven, affecting the balance of the contact force between the roller brush 210 and the ground. Therefore, the battery pack 260 is appropriately positioned on the front of the roller brush 210 to balance the weight distribution of the chassis 200, evenly distribute the contact force between the roller brush 210 and the ground, ensure cleaning effectiveness, and guarantee the stability of the cleaning robot's movement.

[0055] The second duct 280 may be equipped with a filter such as a HEPA filter inside or near the blower 230 to further filter the airflow and reduce the amount of waste flowing to the outside.

[0056] The chassis 200 is also equipped with a walking mechanism for driving the cleaning robot to walk. The walking mechanism includes wheels and steering wheels, and the wheels are connected to the motor drive.

[0057] The above description only discloses some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
