[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 single cone-shaped 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 and is used to clean 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. 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.

[0020] 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 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.

[0021] The secondary separation chamber 20 is coaxially located inside the primary separation chamber 10, and the top of the secondary separation chamber 20 is connected to the primary separation chamber 10 through the first channel 21.

[0022] One end of the exhaust pipe 30 is connected to the top of the secondary separation chamber 20, and the other end of the exhaust pipe 30 can be connected to the fan 230 through the second pipe 280.

[0023] 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 is open; the bottom of the secondary separation chamber 20 is closed.

[0024] Garbage and / or sewage are drawn into the suction port 220 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 spirally or rotates in a 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. Then, the central airflow of the spiral airflow flows along the first channel 21 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 secondary separation chamber 20, 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] Furthermore, 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 processes, achieving thorough separation between the garbage and / or sewage and the airflow, improving the separation effect. Moreover, the separation module 100 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. refer to Figure 6 The bottom of the secondary separation chamber 20 has a sealed structure, for example, achieved by a cap 23. The cap 23 can be connected to the bottom of the secondary separation chamber 20 through a snap-fit, screw-on, or threaded connection, 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 secondary separation chamber 20. Furthermore, the sealed structure helps reduce airflow from or into the bottom of the secondary separation chamber 20, making the secondary separation chamber 20 a more independent space and reducing external influences. Moreover, the cap 23 is detachable, facilitating the cleaning of waste and / or sewage within the secondary separation chamber 20.

[0028] refer to Figure 6The first channel 21 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 21. This avoids the spiral airflow flowing directly to the first channel 21. 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 21 and then to the secondary separation chamber 20 for a second separation. The first channel 21 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 7 The bottom end of the second sidewall 22 is open, meaning the bottom end of the primary separation chamber 10 is also open. This open structure includes features such as through holes, notches, and openings. The wastewater box 240 is located below the first cylinder 1, and the bottom ends of all primary separation chambers 10 are connected to the wastewater box 240. The separated waste and / or wastewater can sink downwards into the wastewater box 240.

[0030] refer to Figure 6 The ratio of the diameter D1 of the first sidewall 14 to the diameter D2 of the second sidewall 22 is between 2.0 and 3.0, that is, the ratio of the diameter D1 of the primary separation chamber 10 to the diameter D2 of the secondary separation chamber 20 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, 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.

[0031] refer to Figure 6 At least the bottom of the second cylinder 2 is a tapered cone shape that tapers downwards, meaning at least the bottom of the secondary separation chamber 20 is a tapered cone shape that tapers downwards. Thus, for example, the bottom of the first sidewall 14 of the second cylinder 2 is a tapered cone shape that tapers downwards, or the entire first sidewall 14 is a tapered cone shape that tapers downwards. The tapered shape of the second cylinder 2 promotes faster downward settling of waste and / or sewage, and also reduces or prevents waste and / or sewage in the sewage box 240 from flowing upwards back into the secondary separation chamber 20.

[0032] refer to Figure 9 Three first channels 21 are evenly arranged; the first channels 21 are arc-shaped and tangentially connected to the second sidewall 22 of the secondary separation chamber 20. As a result, the airflow can flow smoothly to the secondary separation chamber 20.

[0033] refer to Figure 5 and Figure 6 Specifically, the separation module 100 includes a first cylinder 1, a second cylinder 2, and a third cylinder 3; The first cylinder 1 is set vertically, and the second cylinder 2 is coaxially set inside the first cylinder 1; The first sidewall 14 of the first cylinder 1 and the second sidewall 22 of the second cylinder 2 form a primary separation cavity 10, and a secondary separation cavity 20 is formed inside the second cylinder 2.

[0034] The top of the first cylinder 1 is provided with a spiral air duct 11 extending downwards. The spiral air duct 11 includes an air inlet 111 and an air outlet 112. The air outlet 112 is connected to the primary separation chamber 10.

[0035] The top of the secondary separation chamber 20 is provided with a plurality of uniformly arranged first channels 21 that communicate with the primary separation chamber 10.

[0036] The third cylinder 3 is located above or on top of the first cylinder 1. The third cylinder 3 is equipped with an exhaust pipe 30, which is connected to the top of the secondary separation chamber 20.

[0037] refer to Figure 6 The spiral air duct 11 extends spirally downward along the inner side of the first sidewall 14; the first sidewall 14 can be vertically arranged. Thus, the spiral airflow can flow smoothly to the primary separation chamber 10, and then move spirally or circumferentially along the first sidewall 14; the vertical arrangement of the 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.

[0038] refer to Figure 5 and Figure 6 A filter screen 5, which is cylindrical, is installed between the primary separation chamber 10 and the secondary separation chamber 20. 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 or large particles of garbage and / or sewage, further improving the separation effect of garbage and / or sewage.

[0039] 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 22; 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 or prevent the spiral airflow from flowing downward 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.

[0040] The edge of the baffle 6 is provided with an outward and downward extending protruding edge 62, that is, the protruding edge 62 extends close to the first side wall 14 and extends downward, which can cause garbage and / or sewage to sink downward into the sewage box 240.

[0041] refer to Figure 5 , Figure 6 and Figure 8 The top of the first cylinder 1 is provided with an exhaust chamber 13, which is located above the secondary separation chamber 20; The first cylinder 1 is also provided with a central pipe 12, which is coaxially arranged with the secondary separation chamber 20. The upper end of the central pipe 12 is connected to the exhaust chamber 13, and the lower end of the central pipe 12 is connected to the top of the secondary separation chamber 20. The bottom end of the central pipe 12 is lower than the first channel 21. The side of the exhaust chamber 13 is connected to the exhaust pipe 30 of the third cylinder 3.

[0042] Thus, the airflow after separating garbage and / or sewage flows through the central pipe 12 to the exhaust chamber 13, and then flows to the outside through the exhaust pipe 30. The central pipe 12 and the second side wall 22 form a space that facilitates the airflow to perform circular or spiral motion, and the bottom end of the central pipe 12 is lower than the first channel 21, which prompts the airflow to perform 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.

[0043] The top of the second cylinder 2 can be assembled to the inside of the first cylinder 1 by means of screws, clips or screws; The third cylinder 3 can be assembled to the top or above the first cylinder 1 using screws, clips, or other structures. For example, the first cylinder 1, the second cylinder 2 and the third cylinder 3 are connected and fixed by a common first screw. The third cylinder 3 is provided with a first stud. The first cylinder 1 and the second cylinder 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.

[0044] The upper end of the filter screen 5 is fitted onto the top of the first cylinder 1 or the second cylinder 2, and the lower end is inserted into the first annular groove 61 of the baffle 6.

[0045] The baffle 6 can be assembled to the second cylinder 2 by means of a snap fastener, a screw, or a screw; for example, the second cylinder 2 has a second stud on its outer side, the baffle 6 has a corresponding third through hole, and the second screw passes through the third through hole and is screwed to the second stud.

[0046] The cap 23 can be assembled to the bottom of the second cylinder 2 by means of a snap, screw, or thread. For example, the cap 23 is provided with a protruding buckle, and the second cylinder 2 is provided with a buckle groove that mates with the protruding buckle.

[0047] refer to Figure 5 and Figure 6The separation module 100 also includes a first gasket 41 and a second gasket 42; The top of the first cylinder 1 is provided with a first protruding ring 15, which forms an exhaust cavity 13 with the top wall of the third cylinder 3. A first gasket 41 is provided between the top of the first protruding ring 15 and the top wall of the third cylinder 3 to improve the sealing of the connection.

[0048] The second gasket 42 is located at the top of the secondary separation chamber 20, that is, the first gasket 41 is provided between the top of the second cylinder 2 and the top wall of the first cylinder 1, which helps to improve the sealing of the connection.

[0049] refer to Figure 10 and Figure 11 The top of the third cylinder 3 is provided with a rotatable handle 31. The handle 31 is rotatably connected to the third cylinder 3 through a structure of a first convex shaft 32 and a first shaft hole 33, thereby facilitating the extraction or movement of the entire separation module 100.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.
