[0015] 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

[0016] The present invention will now be described in further detail with reference to the accompanying drawings.

[0017] refer to Figures 1 to 8 This refers to a single-cone separation module used in cleaning robots. This module enables the separation of both waste and wastewater. A cleaning robot is an intelligent robotic device capable of performing cleaning tasks automatically or semi-automatically.

[0018] refer to Figures 1 to 6 The separation module 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.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] The spiral air duct 11 has an air inlet 111 connected to the dust suction port of the cleaning robot, and an exhaust pipe 30 connected to a fan, which is used to generate airflow. The sewage box 9 is located below the first cylinder 1 and is used to collect garbage and sewage. The bottom end of the primary separation chamber 10 can be connected to the sewage box 9.

[0024] Garbage and / or sewage are drawn into the suction port 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 circumferentially along the first side wall 14 in the primary separation chamber 10. Garbage and / or sewage move outward under the action of centrifugal force, that is, it causes garbage or sewage to move away from the center of the spiral airflow. Under the action of the self-weight of garbage and / or sewage and the downward inertial component of the spiral motion, garbage and / or sewage gradually move downward or settle and move to the sewage box 9, thus realizing the primary separation of garbage and / or sewage.

[0025] Then, the central airflow of the spiral airflow flows along the first channel 21 to the secondary separation chamber 20. The airflow moves in a circular or spiral motion along the second side wall 22 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.

[0026] Finally, the airflow that has separated the garbage and / or sewage flows upward to the exhaust pipe 30 and is discharged to the outside.

[0027] Thus, the garbage and / or sewage undergo two centrifugal processes, achieving thorough separation from the airflow and improving the separation effect.

[0028] 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.

[0029] refer to Figure 3The 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 second cylinder 2 via 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.

[0030] refer to Figure 3 The 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. Therefore, 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.

[0031] refer to Figure 4 The bottom end of the second sidewall 22 is open, meaning the bottom end of all primary separation chambers 10 is open, with openings including through holes, notches, and vents. The wastewater box 9 is located below the first cylinder 1, and the bottom ends of all primary separation chambers 10 are connected to the wastewater box 9. The separated waste and / or wastewater can sink downwards into the wastewater box 9.

[0032] refer to Figure 3 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.

[0033] refer to Figure 3The spiral 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 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 9.

[0034] refer to Figure 3 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. 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 can promote faster downward settling of garbage and / or sewage, and also reduce or prevent garbage and / or sewage in the sewage box 9 from flowing upwards back into the secondary separation chamber 20.

[0035] refer to Figure 6 Three first channels 21 are evenly arranged; the first channel 21 is arc-shaped and tangentially connected to the second sidewall 22. Thus, the airflow can flow smoothly to the secondary separation chamber 20.

[0036] refer to Figure 2 and Figure 3 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 of the garbage and / or sewage, further improving the separation effect of garbage and / or sewage.

[0037] refer to Figure 2 and Figure 3 It 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 the downward flow of the spiral airflow to the sewage box 9, and also prevent or reduce the upward flow of garbage and / or sewage in the sewage box 9 back to the primary separation chamber 10.

[0038] 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 9.

[0039] refer to Figure 2 , Figure 3 and Figure 5The 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] refer to Figure 2 and Figure 3 It 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.

[0046] The second gasket 42 is located at the top of the secondary separation chamber 20, that is, the second gasket 42 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.

[0047] refer to Figure 7 and Figure 8 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.

[0048] 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.
