DETAILED DESCRIPTION

[0038] The utility model will be further explained in detail in combination with the drawings.

[0039] Reference Figures 1 to 7 A garbage separation device applied to a cleaning robot, the separation device 2 can form spiral air flow, and garbage is separated from the air flow by centrifugal force.

[0040] Reference Figures 1 to 3 The separation device 2 includes a cylinder 210, an end cover 220 and an air outlet pipe 230 and the like.

[0041] The end cover 220 is assembled at one end of the cylinder 210, and the space formed by the end cover 220 and the cylinder 210 constitutes an inner chamber 20.

[0042] The air outlet pipe 230 is arranged inside the cylinder 210, and one end of the air outlet pipe 230 is assembled to the end cover 220.

[0043] The outer side of one end of the air outlet pipe 230 close to the end cover 220 is provided with a spiral piece 211, the spiral piece 211 is arranged around the air outlet pipe 230, and the spiral piece 211 is used to constitute a spiral air duct 21; it can be understood that the spiral piece 211, part of the outer wall surface of the air outlet pipe 230, part of the inner wall surface of the end cover 220 and / or part of the inner wall surface of the cylinder 210 and the like constitute the spiral air duct 21, and the air flow forms spiral air flow under the guidance of the spiral piece 211.

[0044] The end cover 220 is provided with an air inlet 2a connected with the spiral air duct 21; that is, the initial end of the spiral air duct 21 is connected with the air inlet 2a, and the terminal end of the spiral air duct 21 is connected with the inner cavity 20;

[0045] The wall surface of the end of the cylinder body 210 away from the end cover 220 is provided with a separation port 22; thus, the one end of the inner cavity 20 is provided with the spiral air duct 21, and the other end of the inner cavity 20 is provided with the separation port 22, and the air flow flows from the spiral air duct 21 to the separation port 22;

[0046] The wall surface of the end of the air outlet pipe 230 close to the separation port 22 is provided with a through hole 23;

[0047] The end cover 220 is provided with an air outlet 2b connected with the air outlet pipe 230; the air outlet 2b can be coaxially arranged with the air outlet pipe 230;

[0048] The garbage flows into the spiral air duct 21 from the air inlet 2a under the action of the negative pressure air flow, the spiral air duct 21 promotes the air flow to become spiral air flow and flow to the direction of the separation port 22, the garbage is separated from the separation port 22 under the action of the centrifugal force, the separated garbage can be collected in the dust collecting box 1 or other container, the air flow separated from the garbage flows into the air outlet pipe 230 from the through hole 23, and then flows to the air outlet 2b along the air outlet pipe 230, and finally flows to the outside. In this way, the separation device can form spiral air flow, and the garbage is separated from the air flow by using the centrifugal force.

[0049] With reference to Figure 2 The separation port 22 is in a strip shape and is arranged in a circumferential direction along the wall surface of the cylinder body 210. Thus, the garbage can have more time and space to separate from the air flow in the process of spiral motion or circumferential motion, the garbage separation is more sufficient, and the separation efficiency is higher.

[0050] The air outlet pipe 230 is coaxially arranged with the cylinder body 210, which is beneficial to form the spiral air duct 21 and better promote the spiral flow of the air flow in the inner cavity 20.

[0051] With reference to Figure 2 The number of spiral turns of the spiral blade 211 is equal to or greater than 1; it can be understood that the spiral angle of the spiral blade 211 is equal to or greater than 360 degrees, so as to effectively guide the flow direction of the air flow and form the spiral air flow.

[0052] With reference to Figure 2 and Figure 3The through hole 23 is covered with a filter 240. The filter 240 can be a stainless steel filter screen in the shape of a ring, sleeved or clamped on the air outlet pipe 230. In this way, the air flow needs to pass through the filter 240 to flow into the air outlet pipe 230. Due to the different particle sizes or weights of the garbage, different centrifugal forces are obtained, and garbage with smaller particles or lighter weight can be distributed in the central area of the air flow. In order to further reduce or prevent the garbage from flowing to the outside, the filter 240 can be arranged to block the garbage and promote the garbage to stay in the inner cavity 20 for further spiral or circular motion.

[0053] In addition, since the central area of the air flow is basically free of garbage or has little garbage, and the garbage tends to move outward under the action of centrifugal force, the amount of garbage attached to the filter 240 is small, and the filter 240 can be used for a long time without frequent replacement.

[0054] Reference Figure 2 , Figure 4 and Figure 5 The end cover 220 is connected with the barrel 210 through the first screw structure 24, and the first screw structure 24 can be conveniently disassembled and connected.

[0055] The first screw structure 24 includes a first groove body 241, a first limiting boss 242, a first protruding buckle 243 and a first limiting recess 244.

[0056] The inner side of the wall surface of the end cover 220 is provided with the first groove body 241, the first groove body 241 extends circumferentially, the beginning end of the first groove body 241 is open, and the end of the first groove body 241 is provided with the first limiting boss 242.

[0057] The outer side of the wall surface of the barrel 210 is provided with the first protruding buckle 243, and the first protruding buckle 243 is provided with the first limiting recess 244 matched with the first limiting boss 242.

[0058] When assembled, the first protruding buckle 243 enters the first groove body 241 from the beginning end of the first groove body 241, and then rotates relatively to move the first protruding buckle 243 to the end of the first groove body 241. Finally, the first limiting boss 242 is connected with the first limiting recess 244 to realize assembly connection.

[0059] Reference Figure 2 , Figure 6 and Figure 7 The air outlet pipe 230 is connected with the end cover 220 through the second screw structure 25, and the second screw structure 25 can be conveniently disassembled and connected.

[0060] The second screw structure 25 includes a second groove body 251, a second limiting boss 252, a second protruding buckle 253 and a second limiting recess 254.

[0061] The inner side of the wall surface of the air outlet 2b of the end cover 220 is provided with a second groove body 251, the second groove body 251 extends circumferentially, the beginning end of the second groove body 251 is open, and the end of the second groove body 251 is provided with a second limiting boss 252;

[0062] The outer side of the wall surface of the air outlet pipe 230 is provided with a second protruding buckle 253, the second protruding buckle 253 is provided with a second limiting groove 254 matched with the second limiting boss 252;

[0063] During assembly, the second protruding buckle 253 enters the second groove body 251 from the beginning end of the second groove body 251, and then rotates relatively to promote the second protruding buckle 253 to move to the end of the second groove body 251, and finally the second limiting boss 252 is connected with the second limiting groove 254 to realize assembly connection.

[0064] The assembly process of the separation device 2 is as follows:

[0065] The cylinder body 210, the end cover 220, and the air outlet pipe 230 are respectively injection molded, wherein the air outlet pipe 230 is integrally formed with the spiral fin 211, then the filter element 240 is sleeved on the through hole 23 of the air outlet pipe 230, then the air outlet pipe 230 is assembled and connected with the end cover 220 through the second rotating buckle structure 25, then the cylinder body 210 is assembled and connected with the end cover 220 through the first rotating buckle structure 24, thereby completing the assembly of the separation device 2. Thus, the separation device 2 is assembled by the cylinder body 210, the end cover 220, the air outlet pipe 230, and the filter element 240, and is assembled through the rotating buckle structure, which is convenient for manufacturing and assembling.

[0066] Reference Figures 8 to 10 The separation device 2 can be applied to a cleaning robot, and the chassis 7 of the cleaning robot is provided with a walking mechanism and a cleaning mechanism. The walking mechanism is provided with wheels to drive the robot to walk, and the cleaning mechanism can clean the surface to be cleaned.

[0067] The air inlet 2a of the separation device 2 can be connected with the dust suction port 4 of the chassis 7 through the first pipeline 5, and the air outlet 2b can be connected with the negative pressure generator 3 through the second pipeline 6. The negative pressure generator 3 can be a fan or a negative pressure motor to form a negative pressure air flow.

[0068] The separation port 22 of the separation device 2 is connected with the dust collecting box 1, and the dust collecting box 1 is used for storing garbage.

[0069] The separation device 2 can be arranged outside or inside the dust collecting box 1.

[0070] The working principle of the separation device 2 is as follows:

[0071] The negative pressure generator 3 works to form a negative pressure air flow, and garbage is sucked from the dust suction port 4 and flows to the air inlet 2a of the separation device 2 under the action of the negative pressure air flow.

[0072] The spiral air duct 21 of the separation device 2 causes the airflow to flow in a spiral direction, forming a spiral airflow, and flows along the direction A toward the separation port 22;

[0073] Under the action of centrifugation, the garbage is separated from the separation port 22 and enters the dust collection box 1;

[0074] The wind flow after separating the garbage flows to the outside.

[0075] After separating the garbage, the airflow flows to the air outlet duct 230 and flows along direction B to the air outlet 2b, finally flowing to the outside through the negative pressure generator 3. The directions A and B are opposite. Because the flow directions A and B are opposite, the garbage is quite difficult to move toward direction B due to the inertia of centrifugal force. This effectively forces the garbage to remain in the inner cavity 20 and move in a spiral or circular motion before being finally separated into the dust box 1, achieving complete garbage separation.

[0076] Thus, a spiral wind flow is formed by the separation device 2, and the garbage is separated from the wind flow by centrifugal force and collected in the dust box 1, thereby replacing the filter, saving the setting of the filter and reducing the use cost.

[0077] The above disclosure is only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
