Description

Technical Field

[0001] This invention relates to the field of cleaning robot technology, and in particular to an upward suction mechanism and cleaning system. Background Technology

[0002] Cleaning robots need to clean up garbage and wastewater on the ground. Existing cleaning robots use a horizontal spiral separation structure to separate garbage, which only has a single centrifugal separation function, resulting in poor separation effect. They are also not very effective at separating wastewater.

[0003] Furthermore, existing filters are often cylindrical and extend along the axial direction. The spiral airflow flows around the filter, and garbage and / or sewage easily adhere to the surface of the filter, causing the filter holes to become smaller. This, in turn, increases the flow resistance of the airflow, that is, the suction force of the wind decreases and the flow velocity of the airflow decreases, affecting the centrifugal separation effect.

[0004] Furthermore, the waste or sewage in the sewage box is mostly removed by pulling out the box through a drawer-like structure, and then emptying the waste or sewage, which is somewhat inconvenient. Summary of the Invention

[0005] The purpose of this invention is to provide an upward suction mechanism and cleaning system to solve one or more of the above-mentioned technical problems.

[0006] To achieve this objective, the present invention adopts the following technical solution: An upward suction mechanism includes a separation module and a suction docking assembly; The separation module is equipped with a suction pipe that runs vertically through the separation module; The separation module has a wastewater box located below it. The separation module can separate garbage or wastewater into the wastewater box through centrifugal force. The sludge suction docking assembly includes a connecting pipe and a sludge tank. The upper end of the connecting pipe is connected to the sludge tank, and the lower end of the connecting pipe can be inserted into the sludge suction pipe. The manhole cover can move vertically via the drive unit; During vacuuming, the lower end of the connecting pipe moves downward and is inserted into the suction pipe. Under the action of suction, the garbage or sewage in the sewage box is sucked upward and moved to the sewage tank.

[0007] In some embodiments, the drive unit includes a first motor, a first gear, and a first rack; The output end of the first motor is connected to the first gear drive, and the first gear is connected to the first rack drive.

[0008] In some embodiments, the suction docking assembly also includes a second blower connected to the top of the wastewater tank.

[0009] In some implementations, the lower end of the suction pipe is provided with an openable cap.

[0010] In some embodiments, the cover is rotatably connected to the second convex shaft and the second shaft hole structure; The second cam is fitted with a torsion spring.

[0011] In some embodiments, a sealing sheet is provided on the upper surface of the cover.

[0012] In some implementations, the separation module includes a first cavity, a second cavity, and a spiral air duct; The top edge of the first cavity is provided with a spiral air duct, and the middle part of the first cavity is provided with a second cavity; The top of the second cavity is connected to the first cavity through the first channel; The top of the second chamber is connected to the exhaust vent; The bottom of the first cavity is connected to the sewage box; The suction pipe is located in the middle of the first cavity.

[0013] In some embodiments, the suction pipe is coaxially arranged with the first cavity; When there is only one second cavity, the second cavity is coaxially arranged with the first cavity, the suction pipe passes through the second cavity, and the lower end of the suction pipe extends out of the second cavity; When multiple second chambers are set, the multiple second chambers are evenly arranged around the suction pipe.

[0014] In some embodiments, the spiral duct is provided with a spiral guide surface, and the outer and inner sides of the spiral guide surface are respectively provided with a first sidewall and a third sidewall, and the spiral guide surface forms an annular spiral structure from the beginning to the end. The first channel is higher than the end of the spiral guide surface; It also includes a filter screen, which is laid flat over or covered below the first channel; The filter screen is higher than the end of the spiral guide surface.

[0015] In some embodiments, the separation module is further provided with connecting pipes and exhaust chambers. The number of connecting pipes corresponds one-to-one with the number of second chambers. The connecting pipes and second chambers are coaxially arranged. The exhaust chamber is located above the second chamber. The upper end of the connecting pipe is connected to the exhaust chamber, and the lower end of the connecting pipe is connected to the top of the second chamber.

[0016] In some implementations, the bottom of the connecting tube is lower than the first channel.

[0017] A cleaning system includes a cleaning robot and a base station. The cleaning robot is equipped with a wastewater box, and a separation module is located above the wastewater box. The base station is equipped with a sewage suction docking component; When vacuuming, the lower end of the connecting pipe moves downward and is inserted into the suction pipe. The connecting pipe pushes open the cover, and the lower end of the connecting pipe is close to the bottom of the sewage box. Under the action of suction, the garbage or sewage in the sewage box is sucked upward and moved to the sewage tank.

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] refer to Figures 1 to 6 An upward suction mechanism includes a separation module 100 and a suction docking assembly 300; refer to Figure 1 and Figure 2 The separation module 100 is equipped with a suction pipe 34, which penetrates the separation module 100 in a vertical direction. Below the separation module 100 is a sewage box 240, and the separation module 100 can separate garbage or sewage into the sewage box 240 by centrifugal force. refer to Figure 5 and Figure 6The sludge suction docking assembly 300 includes a connecting pipe 310 and a sludge tank 330. For example, the upper end of the connecting pipe 310 is connected to the top of the sludge tank 330, and the lower end of the connecting pipe 310 can be inserted into the sludge suction pipe 34. The connector 310 can move vertically via the drive unit 340; for example, at least the lower end of the connector 310 can move vertically via the drive unit 340. During the suction process, the lower end of the connecting pipe 310 moves downward and is inserted into the suction pipe 34. Under the action of suction, the garbage or sewage in the sewage box 240 is sucked upward and moved to the sewage tank 330.

[0023] Therefore, by means of upward suction, the garbage and / or sewage in the sewage box 240 is sucked out and transported to a preset location such as the sewage tank 330. Compared to simply pulling out the sewage box 240 and emptying the garbage and / or sewage, the upward suction method of this application is more convenient, or provides a new method of sewage suction.

[0024] refer to Figure 6 The drive unit 340 includes a first motor 3410, a first gear 3420 and a first rack 3430; The output end of the first motor 3410 is driven to be connected to the first gear 3420, and the first gear 3420 is driven to be connected to the first rack 3430. The first rack 3430 is connected to the connecting pipe 310, and the first rack 3430 is vertically arranged.

[0025] Thus, the first gear 3420 and the first rack 3430 cooperate to drive the connecting pipe 310 to move vertically, so that the connecting pipe 310 can be inserted downward into the suction pipe 34.

[0026] The upper end of the connecting pipe 310 can be a flexible hose with a certain degree of bending and deformation capability; the lower end of the connecting pipe 310 can be a rigid pipe for easy insertion into the suction pipe 34. The first rack 3430 can be connected to the rigid pipe. Of course, the connecting pipe 310 can also be a telescopic pipe structure.

[0027] refer to Figure 6 The sludge suction docking assembly 300 also includes a second blower 320, for example, the second blower 320 is connected to the top of the sludge tank 330. Thus, the second blower 320 is used to generate negative pressure suction to form an airflow for sludge suction.

[0028] refer to Figures 2 to 4The lower end of the suction pipe 34 is provided with an openable and closable cover 35. The cover 35 can open and close the lower end of the suction pipe 34. In the suction state, the cover 35 can be opened, so that the connecting pipe 310 can be inserted into the suction pipe 34 and inserted to the bottom of the sewage box 240. In the non-suction state, such as in the garbage or sewage separation state, the cover 35 is in the closed state to prevent garbage and / or sewage from flowing out or leaking from the suction pipe 34.

[0029] refer to Figure 4 The cover 35 is connected to the second shaft hole 36 through the structure of the second convex shaft 351. The second convex shaft 351 is fitted with a torsion spring 37. Thus, the torsion spring 37 uses its elastic force to keep the cover 35 in a closed state and can drive the cover 35 to return to its original position.

[0030] refer to Figure 4 A sealing sheet 352 is provided on the upper surface of the cover 35. The sealing sheet 352 can be made of silicone or sponge, etc., to improve the sealing performance when closed. The sealing sheet 352 can be attached to or embedded in the upper surface of the cover 35.

[0031] refer to Figure 5 During vacuuming, the lower end of the connecting pipe 310 is inserted into the suction pipe 34. The connecting pipe 310 pushes open the cover 35, causing its lower end to approach the bottom of the wastewater box 240. The second blower 320 starts, generating negative pressure suction. The garbage and / or wastewater in the wastewater box 240 flows upward under the action of suction and flows into the wastewater tank 330. After vacuuming is completed, the connecting pipe 310 moves away from the suction pipe 34, and the cover 35 returns to its original position under the action of the torsion spring 37, closing the lower end of the suction pipe 34.

[0032] refer to Figures 7 to 12 The separation module 100 includes a first cavity 10, a second cavity 20, and a spiral air duct 11; The first cavity 10 is vertically arranged and cylindrical; The top edge of the first cavity 10 is provided with a spiral air duct 11, which causes the airflow to spiral downward. The middle part of the first cavity 10 is provided with a second cavity 20. The top of the second cavity 20 is connected to the first cavity 10 through the first channel 22; The spiral duct 11 is provided with an air inlet 111, and the top of the second cavity 20 is connected to the air outlet 131; wherein, the air inlet 111 is connected to the sewage suction port, and the air outlet 131 is connected to the first fan 230, which is used to generate negative pressure suction to form airflow; The bottom end of the first cavity 10 is connected to the sewage box 240; the bottom end of the first cavity 10 may be an open structure, which has a through hole, notch, or open opening.

[0033] 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 rotates in a circle within the first cavity 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.

[0034] Then, the central airflow of the spiral airflow flows along the first channel 22 to the second cavity 20. The airflow performs circular or spiral motion in the second cavity 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 second cavity 20, etc., to achieve secondary separation of garbage and / or sewage.

[0035] Finally, the airflow that has separated the garbage and / or sewage flows upward to the exhaust vent 131 and is then discharged to the outside.

[0036] Thus, the garbage and / or sewage undergo two centrifugal processes, achieving thorough separation from the airflow and improving the separation effect.

[0037] In addition, most or large particles of garbage and / or sewage have been separated in the first 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 second 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 100 can not only separate garbage but also sewage, improving the cleaning effect and increasing applicability.

[0038] refer to Figure 8 The suction pipe 34 is located in the middle of the first cavity 10; for example, the suction pipe 34 is coaxially arranged with the first cavity 10.

[0039] refer to Figure 3 , Figure 8 and Figure 11When there is only one second cavity 20, it is coaxially arranged with the first cavity 10. The suction pipe 34 passes through the second cavity 20, with its lower end extending out of the second cavity 20, meaning the lower end of the suction pipe 34 is below the second cavity 20. The suction pipe 34 can also be coaxially inserted inside the connecting pipe 12, with its diameter smaller than the diameter of the connecting pipe 12. Thus, the connecting pipe 12, the second cavity 20, the suction pipe 34, and the first cavity 10 can all be coaxially arranged, facilitating stable airflow and a compact structure. At this time, the cover 35 is rotatably connected to the lower part or bottom of the second cavity 20. Furthermore, the second cavity 20 can communicate with the first cavity 10 through multiple first channels 22.

[0040] refer to Figure 13 and Figure 15 When multiple second cavities 20 are configured, they are evenly arranged around the suction pipe 34, with the lower end of the suction pipe 34 below the second cavities 20. Each of the multiple second cavities 20 is connected to the first cavity 10 via multiple first channels 22, meaning the number of second cavities 20 corresponds one-to-one with the number of first channels 22. The suction pipe 34 and the first cavity 10 can be coaxially arranged.

[0041] Therefore, the second cavity 20 can be set to one to ten or more.

[0042] The bottom of the second cavity 20 can be a sealed structure or an open structure. Preferably, it is a sealed structure. Since less waste and / or sewage flows into the second cavity 20, the separated waste and / or sewage can settle to the bottom of the second cavity 20. Furthermore, the sealed structure helps reduce airflow from the bottom of the second cavity 20, or reduces airflow from the bottom of the second cavity 20, thus creating a more independent space for the second cavity 20 and reducing external influences.

[0043] refer to Figure 10 The first cavity 10 includes a first sidewall 14, which surrounds the first cavity 10. The first sidewall 14 is vertically arranged, which facilitates a stable spiral flow of air.

[0044] refer to Figure 10 The spiral air duct 11 is provided with a spiral guide surface 113. The outer side and the inner side of the spiral guide surface 113 are respectively provided with a first side wall 14 and a third side wall 17. That is, the spiral guide surface 113, the first side wall 14 and the third side wall 17 form the spiral air duct 11. The spiral air duct 11 is coaxially arranged with the first cavity 10. The spiral guide surface 113 forms an annular spiral structure from the beginning end 113a to the end end 113b; the air inlet 111 is connected to the beginning end 113a of the spiral guide surface 113. Thus, a spiral downward airflow is formed under the guidance of the spiral guide surface 113.

[0045] refer to Figure 10 The third sidewall 17 forms a recessed area 16, such that the recessed area 16 is coaxially arranged with the first cavity 10, and the recessed area 16 is used to accommodate the top of the second cavity 20 and the first channel 22. The recessed wall 161 of the recessed area 16 may be higher than the beginning 113a of the spiral guide surface 113.

[0046] The first channel 22 is at least higher than the end 113b of the helical guide surface 113, or at least higher than the bottom of the third sidewall 17. Of course, the first channel 22 may be higher than the beginning 113a of the helical guide surface 113.

[0047] Therefore, when the spiral airflow reaches the first cavity 10, it first undergoes a spiral or circular motion downwards due to inertia, then bypasses the third sidewall 17 and flows upwards to the first channel 22, avoiding the spiral airflow from flowing directly to the first channel 22. After the garbage and / or sewage have undergone a certain degree of separation in the first cavity 10, the airflow flows to the first channel 22 and then to the secondary separation chamber for a second separation. Therefore, the first channel 22 is at least higher than the end 113b of the spiral guide surface 113 or the bottom of the third sidewall 17, forming a certain degree of spatial distance to ensure that there is a certain time sequence between the primary and secondary separation of garbage and / or sewage.

[0048] refer to Figure 8 and Figure 10 The bottom end of the third sidewall 17 is not higher than the end 113b of the spiral guide surface 113. For example, the bottom end of the third sidewall 17 may be flush with or slightly lower than the end 113b of the spiral guide surface 113, or the bottom end of the third sidewall 17 may protrude downwards beyond the end 113b of the spiral guide surface 113. This further promotes the spiral airflow to first spiral or circularly move downwards under inertia when it reaches the first cavity 10, and then flows upwards towards the first channel 22. It also prevents or reduces the movement of garbage and / or sewage towards the center, promoting more thorough separation of garbage and / or sewage.

[0049] refer to Figure 7 and Figure 8 The separation module 100 also includes a filter screen 4, which is horizontally positioned to cover or cover the bottom of the first channel 22. "Horizontally positioned" can be understood as a horizontal arrangement. The filter screen 4 has filter holes 40.

[0050] The filter screen 4 is placed horizontally under the first channel 22, so that there is a filter screen 4 between the first cavity 10 and the second cavity 20. As a result, the airflow first passes through the filter screen 4, then flows to the first channel 22, and then flows to the second cavity 20, thereby filtering garbage and / or sewage and further improving the separation effect.

[0051] Furthermore, the filter screen 4 is placed horizontally. Garbage and / or sewage move outward under the action of centrifugal force and settle downward under the action of their own weight, thereby reducing contact with the filter screen 4 and reducing the adhesion of garbage and / or sewage to the filter screen 4. This can prevent or reduce the increase of wind resistance and ensure smooth airflow and wind suction.

[0052] The filter screen 4 is not lower than the end 113b of the spiral guide surface 113, or the filter screen 4 is not lower than the bottom end of the third side wall 17; that is, both the first channel 22 and the filter screen 4 are higher than the end 113b of the spiral guide surface 113 or the bottom end of the third side wall 17.

[0053] Therefore, under the action of centrifugal force and its own weight, there is less garbage and / or sewage at the top of the middle part of the spiral airflow. The filter screen 4 is not lower than the end 113b of the spiral guide surface 113 or the bottom of the third side wall 17, which further reduces the contact between garbage and / or sewage and the filter screen 4, reduces the adhesion of garbage and / or sewage to the filter screen 4, and better ensures the smooth flow of air and the suction of the wind.

[0054] Furthermore, since the filter screen 4 is basically located at the top of the first cavity 10, after the spiral airflow flows into the first cavity 10, the filter screen 4 will not obstruct the flow of the spiral airflow. The flow resistance of the spiral airflow is smaller, the flow is smoother, and it is easier to form a stable spiral airflow. As a result, the centrifugal force obtained by the garbage and / or sewage is greater and more stable, and the separation is more complete. At the same time, during the sedimentation process of garbage and / or sewage, the filter screen 4 at the top will not cause obstruction, and the garbage and / or sewage can settle more smoothly into the sewage box 240, improving the separation effect of garbage and / or sewage.

[0055] The filter screen 4 can be ring-shaped, and the shape of the filter screen 4 can be set appropriately according to the situation.

[0056] refer to Figure 8 At least the bottom of the second cavity 20 is a tapered shape that gradually narrows downwards. For example, the bottom of the second cavity 20 is a tapered shape that gradually narrows downwards, or the entire second cavity 20 is a tapered shape that gradually narrows downwards. The tapered shape of the second cavity 20 can promote the sinking of garbage and / or sewage more quickly.

[0057] refer to Figure 7 and Figure 8 The separation module 100 is also provided with a connecting pipe 12 and an exhaust chamber 13. The number of connecting pipes 12 corresponds one-to-one with the number of second cavities 20. The connecting pipes 12 and the second cavities 20 are coaxially arranged. The exhaust chamber 13 is located above the second cavity 20. The upper end of the connecting pipe 12 is connected to the exhaust chamber 13, and the lower end of the connecting pipe 12 is connected to the top of the second cavity 20.

[0058] 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 port 131; wherein, the connecting pipe 12 and the second chamber 20 form a space that facilitates the airflow to perform circular or spiral motion.

[0059] Furthermore, the bottom 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.

[0060] When the second cavity 20 is provided, the suction pipe 34 is coaxially located inside the connecting pipe 12.

[0061] When multiple second cavities 20 are provided, the number of second cavities 20 corresponds one-to-one with the number of connecting pipes 12.

[0062] refer to Figure 7 and Figure 16 The top of the separation module 100 is provided with a rotatable handle 31. The handle 31 is rotatably connected to the first shaft hole 33 through the structure of the first convex shaft 32, thereby facilitating the extraction or movement of the entire separation module 100.

[0063] refer to Figure 7 The separation module 100 includes a first component 1, a second component 2, and a third component 3, etc. The first component 1 is vertically arranged. The first component 1 is provided with a first side wall 14 and a spiral air duct 11, etc. The first side wall 14 forms a first cavity 10. The first component 1 also includes a recessed area 16, a connecting pipe 12, and an exhaust chamber 13.

[0064] The second component 2 is located inside the first component 1. The second component 2 has a cone 21 and a first channel 22. The cone 21 forms a second cavity 20 inside, and the first channel 22 is located at the top of the second component 2. One to ten cones 21 can be provided, thus having one to ten second cavities 20.

[0065] The cover 35 is rotatably located below or at the bottom of the second component 2.

[0066] The third component 3 is located above or on top of the first component 1, and the third component 3 is equipped with a suction pipe 34 and a handle 31, etc.

[0067] The first component 1 and the second component 2 can be assembled using screws, clips, or screws; The third component 3 can be assembled on top of or above the first component 11 using screws, clips, or other structures. The filter screen 4 can be assembled by means of snaps, screws, threads or adhesive.

[0068] refer to Figures 17 to 21 A cleaning system includes a cleaning robot 200 and a base station 400; refer to Figure 17 and Figure 18 The cleaning robot 200 is equipped with a sewage box 240, and a separation module 100 is provided above the sewage box 240. The cleaning robot 200 is equipped with a chassis 200a, which is equipped with a roller brush 210, a dust suction port and a wastewater box 240. The dust suction port is located on one side of the roller brush 210. The air inlet 111 of the separation module 100 is connected to the dust suction port through a first pipe 270, and the exhaust port 131 is connected to the first fan 230 through a second pipe 280. A filter such as a HEPA filter 290 can be installed between the exhaust port 131 and the first fan 230.

[0069] The chassis 200a is also provided with a limiting groove 250, which is used to place the sewage box 240 and the separation module 100, and to limit the position of the sewage box 240 and the separation module 100. Both the separation module 100 and the sewage box 240 are roughly cylindrical, and their outer diameters are roughly the same.

[0070] refer to Figure 19 The chassis 200 also includes a slidable sliding bracket 260, which has a rotatable roller brush 210, allowing the roller brush 210 to slide or move horizontally outward, i.e., extend horizontally outward. The sliding bracket 260 achieves horizontal sliding or movement through a structure consisting of a second motor 2610, a second gear 2620, and a second rack 2630. The second motor 2610 is fixed to the chassis 200, and its output end is driven by the second gear 2620. The second gear 2620 is driven by the second rack 2630, which is fixedly connected to the sliding bracket 260 and is arranged along the length of the roller brush 210, i.e., along the sliding direction. A guide structure such as a slide rail may be provided between the sliding bracket 260 and the chassis 200.

[0071] 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.

[0072] refer to Figure 20 and Figure 21 The base station is equipped with a suction docking component 300; the suction docking component 300 is located above the base 410, which is used to dock with the cleaning robot 200.

[0073] When the amount of garbage and / or sewage in the sewage box 240 of the cleaning robot 200 reaches a preset level, the cleaning robot 200 moves to a preset position on the base 410 of the base station 400. Then, the drive unit 340 drives the lower end of the connecting pipe 310 downward and inserts it into the suction pipe 34. The connecting pipe 310 pushes the cover 35 downward, and the lower end of the connecting pipe 310 approaches the bottom of the sewage box 240. The second fan 320 starts to generate airflow. Under the action of suction, the garbage or sewage in the sewage box 240 is sucked upward and moved to the sewage tank 330. After the suction is completed, the connecting pipe 310 moves away from the suction pipe 34, and the cover 35 is reset under the action of the torsion spring 37 to close the lower end of the suction pipe 34.

[0074] The above description only discloses some embodiments of the present invention. For those skilled in the art, various 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 invention.
