With rapid development of technology, the living standard of people is greatly improved, and more families begin to reduce the labor intensity and improve the living quality by means of various cleaning devices. Cleaning equipment (e.g., sweeping robots, floor washers, etc.) on the market is typically comprised of two parts, a base station for cleaning the floor and a host machine for recycling the waste collected by the host machine. With the progress of technology, part of base stations can also clean the cleaning part of the host machine, and charge or automatically add and drain the host machine.

Taking a sweeping robot as an example, the base station mainly comprises a clean water tank, a sewage tank, a dust bucket, a recharging module and the like. When the base station washs the rag dish of robot of sweeping floor, the clean water tank can be to the rag moisturizing of robot bottom of sweeping floor, then the robot of sweeping floor drives the rag dish rotatory, through the friction of rag dish and base station tray, the rag dish can obtain the cleanness, and the sewage that above-mentioned cleaning process produced can be retrieved to the sewage case by the base station. Meanwhile, the base station can be in butt joint with a dust box in the sweeping robot, so that solid wastes such as hairs, paper scraps and the like in the dust box are recycled to the dust barrel.

Because some solid rubbish is insoluble in water, and hair, waster and other rubbish mixes in sewage and blocks up the sewer easily, so sewage case and dirt bucket in the basic station are usually designed into two containers of mutually independent to retrieve sewage and solid rubbish respectively, this just makes the user when clearing up the basic station, need maintain sewage case and dirt bucket respectively, and the operation is comparatively loaded down with trivial details, and two mutually independent containers also can occupy more organism spaces, be unfavorable for the organism miniaturization. In some products, the base station has an automatic water feeding and discharging function, but in order to avoid the blockage of a sewer by solid-liquid mixed garbage, the water discharging function is only aimed at liquid garbage in a sewage tank, and a user still needs to clean a dust bin in person, so that the use experience of the user is poor.

Therefore, how to improve the recovery device to optimize the recovery process of the solid garbage and the liquid garbage and simplify the later cleaning steps of the user is a problem to be solved in the art.

In view of the above problems, the present application provides a cleaning base station, please refer to fig. 1 to 5 together, which at least includes a control system, a base (not shown) and a recovery device a. In practical application, the cleaning base station can be in butt joint with a host machine such as a sweeping robot and a floor washing machine. The cleaning base station is provided with corresponding functional modules so as to charge and automatically charge and drain the host machine, and the cleaning base station can also utilize a cleaning module arranged in the base to clean cleaning components (such as a rag disc, a rolling brush and the like) on the host machine.

In the present embodiment, the base is provided with at least one docking passage for communicating the host and the tub 1 in the recovery device a, the recovery device a being located inside the base, and the tub 1 in the recovery device a having a plurality of passages. For example, it is assumed that the base has two docking channels (designated as docking channel a, docking channel b), and the tub 1 has at least two recovery channels (designated as recovery channel a, recovery channel b), wherein one end of the docking channel a communicates with the recovery channel a, and one end of the docking channel b communicates with the recovery channel b. When the host machine is in butt joint with the cleaning base station, the other end of the butt joint channel a can be in butt joint with a dust box in the host machine, and the other end of the butt joint channel b can be in butt joint with a sewage box in the host machine. In this way, the host and the barrel 1 can be communicated together through the butt joint channel a and the butt joint channel b, and the solid garbage and/or liquid garbage collected by the host can be transferred into the barrel 1.

The inside of staving 1 is provided with crushing subassembly 2, and specifically, crushing subassembly 2 can be through draw-in groove buckle isotructure detachably assembly in the inside of staving 1. When external solid materials (such as solid garbage collected in a main machine dust box and water-insoluble particles generated after the main machine is cleaned by a cleaning tray) enter the barrel body 1 through the corresponding recycling channel, the crushing assembly 2 can crush the solid materials into fine particles.

In this embodiment, a flow sensor may be disposed in each channel on the barrel 1, and a displacement sensor, a docking sensor and other devices may be disposed in the base, where the control system may collect signals of the sensors, and further obtain flow information, host docking information and the like of each channel on the barrel 1, and then the control system may control the opening and closing states of each channel and the working state of the crushing assembly 2 based on a preset crushing policy, so as to further achieve different recovery effects.

In one possible embodiment, the cleaning station has a cleaning function. Specifically, be provided with the cleaning tray in the base, the surface of cleaning tray is provided with friction parts such as scraper blade, lug, and after host computer and clean basic station dock, the host computer just is located the top of cleaning tray. When the host machine drives the components such as the rag disc, the rolling brush and the like at the bottom of the host machine to rotate, the friction piece on the surface of the cleaning tray can scrape the components, so that the host machine is cleaned. Furthermore, the cleaning base station can spray cleaning liquid to the bottom of the cleaning tray or the host machine so as to improve the cleaning effect.

In this embodiment, the barrel 1 has a first recovery channel 12 and a second recovery channel 13, and the base has a first docking channel, wherein one end of the first docking channel is used for docking with the dust box of the host machine, and the other end of the first docking channel is communicated with the first recovery channel 12 so as to transfer the solid garbage in the dust box to the inside of the barrel 1 through the first recovery channel. The second recovery channel 13 is communicated with the cleaning tray in the base, and the second recovery channel 13 is used for recovering liquid materials in the cleaning tray to the inside of the barrel body 1.

It should be noted that the liquid materials in the cleaning tray include, but are not limited to: the cleaning base station cleans the host machine, and the sewage generated when the cleaning base station cleans the host machine, the cleaning liquid sprayed to the cleaning tray by the cleaning base station, the clean water and the like. In practical applications, the liquid material in the cleaning tray may also contain particles or hairs, which are partially insoluble in water, and the liquid material only indicates that its flow form is liquid, not to limit it to be pure liquid. The cleaning base station can utilize devices such as a vacuum pump or a negative pressure fan to transfer the solid garbage and the liquid material into the barrel body 1. The specific structure and arrangement of the vacuum pump or the negative pressure fan and other devices can refer to the prior art, and the application is not repeated.

In real life, the inside of host machines such as washing machine still is provided with the sewage case. For such a host, in one achievable embodiment, the base further has a second docking channel, wherein one end of the second docking channel is for docking with a sewage tank of the host, and the other end of the second docking channel is in communication with the second recycling channel 13 to transfer the liquid waste in the sewage tank to the inside of the tank body 1 through the second recycling channel 13. In other words, in the present embodiment, the second recycling channel 13 communicates with both the washing tray and the second docking channel, and both the liquid waste in the main tank and the liquid material in the washing tray can be recycled to the inside of the tub 1. The structure can expand the application range of the cleaning base station, so that the cleaning base station can recycle the solid garbage in the host machine and the liquid garbage in the host machine.

Further, the tub 1 further has a negative pressure line 11, and the pulverizing assembly 2 is located in a downstream region of the first recovery passage 12 and the second recovery passage 13. In the present embodiment, the recovery device a is provided with a negative pressure device (not shown) to which the negative pressure line 11 communicates. When the negative pressure device works, the negative pressure device can pump out the gas in the barrel body 1 through the negative pressure pipeline 11, so that negative pressure is generated in the barrel body 1, and external materials can enter the barrel body 1 through the first recovery channel 12 or the second recovery channel 13 and further enter the crushing assembly 2, wherein the external materials comprise at least one of solid garbage and liquid garbage collected by a host machine and liquid materials in a cleaning tray.

For convenience of description, the present application limits the first recovery passage 12 to be used for recovering solid waste such as dust, hair, etc., and the second recovery passage 13 to be used for recovering liquid waste and liquid material. It should be noted that the above limitation is only for the purpose of defining that the first 12 and second 13 recovery channels are used for recovering different types of material, respectively, and is not intended to mean that the first recovery channel 12 can only recover solid waste and the second recovery channel 13 can only recover liquid material. Indeed, in some cases the first recycling channel 12 may be used for recycling liquid material, while the second recycling channel 13 is correspondingly used for recycling solid waste.

Further, the tub 1 is further provided with a water outlet pipe 14, wherein the pulverizing assembly 2 is located in an upstream area of the water outlet pipe 14. Thus, the solid garbage entering the barrel body 1 through the first recovery channel 12 and the liquid garbage and the liquid material entering the barrel body 1 through the second recovery channel 13 enter the crushing assembly 2, and then the liquid garbage and the liquid material after being treated by the crushing assembly 2 flow to the water outlet pipeline 14, and finally the liquid material and/or the liquid garbage and/or the crushed solid material are discharged from the barrel body 1 through the water outlet pipeline 14.

Taking the sweeping robot as an example, the recovery device a may be integrated in a base station that the sweeping robot is equipped with, and the second recovery passage 13 is provided to communicate with a cleaning tray in the base station. When the sweeping robot moves to the base station, the recycling device a can utilize the docking mechanism to communicate the first recycling channel 12 with the dust box in the sweeping robot, so that the dust, hair and other solid wastes in the dust box are collected into the barrel body 1. After the base station cleans the cleaning cloth tray at the bottom of the sweeping robot, the sewage generated by cleaning is collected on the cleaning tray of the base station, and the recycling device A can collect the sewage into the barrel body 1 through the second recycling channel 13.

The crushing assembly 2 is disposed in the barrel 1, specifically, the crushing assembly 2 can be detachably assembled in the barrel 1 through a clamping groove buckle and other structures, and the crushing assembly 2 is located at the downstream of the first recovery channel 12 and the second recovery channel 13, and the crushing assembly 2 is located at the upstream of the water outlet pipeline 14. Thus, the external materials (such as sewage, dust, hair and the like) entering the barrel body 1 can fall into the crushing assembly 2, and the external materials can be discharged from the barrel body 1 through the water outlet pipeline 14 after being processed by the crushing assembly 2. Further, the outer contour of the crushing assembly 2 can be matched with the inner contour of the barrel body 1, so that the crushing assembly 2 is nested in the barrel body 1, and external materials are prevented from leaking from a gap between the barrel body 1 and the crushing assembly 2 without being processed by the crushing assembly 2. Preferably, the barrel body 1 is cylindrical, the outer contour of the crushing assembly 2 is also cylindrical, and the diameter of the outer contour of the crushing assembly 2 is slightly smaller than the inner diameter of the barrel body 1.

It should be noted that the negative pressure device may be a mechanical device of the type of a vacuum pump, a negative pressure fan or the like, and the negative pressure device may be present as a part of the recovery device a, which may be formed as an integral part with the recovery device a. Of course, the negative pressure device can also be arranged in other structures as an independent component, for example, the negative pressure device can be arranged in the base, the installation position and the specific type of the negative pressure device are not limited, and only the negative pressure device can be ensured to generate negative pressure in the barrel body 1 through the negative pressure pipeline 11.

To avoid solid waste or liquid waste entering the negative pressure line 11, in one possible embodiment, the negative pressure line 11 and the first recovery channel 12 are located on different walls of the tank 1, or the negative pressure line 11 and the second recovery channel 13 are located on different walls of the tank 1, so that a longer distance is maintained between the negative pressure line 11 and the first recovery channel 12, or between the negative pressure line 11 and the second recovery channel 13. When the solid garbage or the liquid garbage moves between the intervals, the solid garbage or the liquid garbage can fall downwards under the action of gravity, so that the solid garbage or the liquid garbage is prevented from entering the negative pressure pipeline 11.

For example, referring to the view angle shown in fig. 1, the tub 1 has an up-down orientation, the negative pressure pipe 11 and the second recovery passage 13 may be provided on an upper wall surface of the tub 1, and the first recovery passage 12 may be provided on a side wall surface of the tub 1. Thus, after the solid garbage enters the interior of the barrel body 1 from the first recovery channel 12, the solid garbage falls downwards under the action of gravity, and the falling direction of the solid garbage is opposite to the setting position of the negative pressure pipeline 11, so that the solid garbage is prevented from entering the negative pressure pipeline 11. Of course, the negative pressure line 11 and the first recovery passage 12 may be provided on the upper wall surface of the tub 1, and the second recovery passage 13 may be provided on the side wall surface of the tub 1. Preferably, the negative pressure line 11 is located on a side wall surface of the tub 1, and the first recovery passage 12 and the second recovery passage 13 are located on a side wall surface of the tub 1.

In one possible embodiment, the tub 1 has at least one air flow baffle 16, the air flow baffle 16 extends from an inner surface of an upper wall surface of the tub 1 toward an inside of the tub 1, and the air flow baffle 16 is adjacent to the negative pressure pipe 11. The airflow baffle 16 can block the flow of the airflow, a baffling effect is formed inside the barrel body 1, when the airflow carrying a large amount of tiny solid particles/liquid particles encounters the airflow baffle 16, the airflow can be folded around the airflow baffle 16 to flow away and enter the negative pressure pipeline 11, and the solid particles/liquid particles can continue to move forwards due to inertia and collide with the airflow baffle 16. The solid particles will fall directly into the bottom of the bowl 1 and the liquid particles will adhere to the surface of the airflow baffle 16 and eventually pool into large droplets that fall off the airflow baffle 16. By providing the gas flow baffle 16 near the negative pressure line 11, the gas entering the negative pressure line 11 can be further subjected to gas-liquid/gas-solid separation, thereby reducing liquid particles or solid particles carried in the gas.

It should be particularly noted that although the air flow baffle 16 extends from the inner surface of the upper wall surface of the tub 1 toward the inside of the tub 1, the air flow baffle 16 does not partition the tub 1 into two chambers which are not communicated with each other, i.e., the air in the lower/upper space of the air flow baffle 16 may still flow into the upper/lower space of the air flow baffle 16, or the air in the left/right space of the air flow baffle 16 may still flow into the right/left space of the air flow baffle 16.

Further, the air inlet of the negative pressure pipeline 11 is provided with filter cotton, and the filter cotton can filter the air entering the negative pressure pipeline 11, so that solid particles or liquid drops are prevented from entering the negative pressure pipeline 11.

In one embodiment, the negative pressure line 11, the first recovery passage 12, the second recovery passage 13, and the water outlet line 14 are provided with a solenoid valve 111, a solenoid valve 121, a solenoid valve 131, and a solenoid valve 141, respectively. The solenoid valve 111, the solenoid valve 121, the solenoid valve 131 and the solenoid valve 141 may be opened or closed based on signals sent by the control system, so as to adjust the open/close states of the negative pressure pipeline 11, the first recovery channel 12, the second recovery channel 13 and the water outlet pipeline 14, so as to achieve different recovery effects.

Further, the control system is further configured to detect medium flow information in the first recovery channel 12 and the second recovery channel 13, and suspended matter content in the tub 1, and control opening and closing states of the negative pressure pipe 11, the first recovery channel 12, the second recovery channel 13, and the water outlet pipe 14 based on the medium flow information and the suspended matter content. In practical applications, a solid flowmeter may be disposed in the first recovery channel 12, where the solid flowmeter is used to obtain flow information of the solid garbage in the first recovery channel 12; a liquid flowmeter is arranged in the second recovery channel 13, and is used for acquiring flow information of liquid medium (such as liquid garbage and liquid materials) in the second recovery channel 13; a photometer is arranged in the barrel body 1 and is used for acquiring the suspended matter content of the liquid in the barrel body 1. The flow information of the solid garbage, the flow information of the liquid medium and the suspended matter content can be fed back to the control system, and the control system uses the information to control the opening and closing states and the opening and closing sequences of the negative pressure pipeline 11, the first recovery channel 12, the second recovery channel 13 and the water outlet pipeline 14, and simultaneously combines with a preset crushing strategy to control the recovery and crushing sequences of the liquid material and the solid material, thereby realizing different recovery effects. The preset pulverizing strategy will be described in detail later.

In one possible embodiment, the cleaning station is provided with a clear water pipe joint (not shown) and a sewer pipe joint (not shown). The fresh water coupler communicates with an external water source (e.g., a tap water pipe in a household) so that a user can supplement fresh water to the cleaning base station through the external water source. One end of the sewage pipe joint is communicated with the water outlet pipeline 14, and the other end of the sewage pipe joint is communicated with an external sewage pipeline (such as a sewer pipeline in a household), so that liquid materials and/or liquid garbage and/or crushed solid materials flowing out of the water outlet pipeline 14 can be discharged into the external sewage pipeline.

In one possible embodiment, the open and closed states of the clean water pipe joint and the sewer pipe joint can be switched manually by a user, for example, valves can be arranged at the clean water pipe joint and the sewer pipe joint, and the user can switch the open and closed states of the clean water pipe joint and the sewer pipe joint by unscrewing or closing the valves. In another realizable embodiment, the clear water pipe joint is provided with a clear water electromagnetic valve, and the clear water electromagnetic valve is used for controlling the opening and closing states of the clear water pipe joint; the sewage pipe joint is provided with a sewage electromagnetic valve, and the sewage electromagnetic valve is used for controlling the opening and closing states of the sewage pipe joint. Specifically, the control system is electrically connected with the clean water electromagnetic valve and the sewage electromagnetic valve, and can send electric signals to the clean water electromagnetic valve and the sewage electromagnetic valve so as to control the clean water electromagnetic valve and the sewage electromagnetic valve to be opened or closed, thereby realizing the switching of the opening and closing states of the clean water pipe joint and the sewage pipe joint.

In one possible embodiment, the pulverizing assembly 2 has a pulverizing function that can perform a pulverizing operation on the solid material entering the interior of the pulverizing assembly 2. For example, the pulverizing unit 2 may perform the pulverizing operation of the above solid materials by using a roller-type pulverizing mechanism, a jaw-type pulverizing mechanism, a blade-type pulverizing mechanism, or the like. When the solid material is crushed by the crushing unit 2, it is formed into a large amount of fine particles, which can be mixed with the liquid material, and then flows out of the crushing unit 2 and finally discharged from the tub 1 through the water outlet pipe 14. Since the solid materials have become tiny particles, even if the particles are insoluble in water, the particles will not block the sewer, which solves the problem that the solid-liquid mixed garbage is easy to block the sewer.

In one possible embodiment, the pulverizing assembly 2 comprises a cutter head 21, a pulverizing container 22 and a driving part 23, wherein the shape of the pulverizing container 22 is adapted to the inner contour of the tub 1, so that the pulverizing container 22 can be nested inside the tub 1, and thus solid material and liquid material entering the inside of the tub 1 can fall into the pulverizing container 22. In practical use, the crushing container 22 is substantially bowl-shaped concave and is sleeved inside the barrel body 1, and at least one opening 221 is formed in the bowl bottom of the bowl-shaped concave, and the crushing container 22 is communicated with the barrel body 1 through the opening 221.

The cutter head 21 is disposed inside the pulverizing container 22, and the driving part 23 is connected to the cutter head 21 through a driving shaft 231, so that the driving part 23 can rotate the cutter head 21 through the driving shaft 231. The outer peripheral surface of the cutterhead 21 is provided with facets which, when the cutterhead 21 is rotated, can cut solid material to cut large pieces of solid material into small pieces of granular objects.

The diameter of the cutterhead 21 is smaller than the caliber of the crushing container 22 so as to prevent the cutterhead 21 rotating at high speed from scratching the crushing container 22. To increase the service life of the pulverizing container 22, the pulverizing container 22 may have a double-layered structure, the inner liner layer may be made of stainless steel to prevent sewage corrosion and increase wear resistance, and the outer liner layer may be made of plastic to reduce the weight of the structure. Of course, the pulverizing container 22 may be entirely made of stainless steel, and the present application is not limited thereto.

Referring to the view angle shown in fig. 1, in one possible embodiment, the driving shaft 231 is disposed outside the tub 1 in a vertical direction, and the first end 2311 of the driving shaft 231 sequentially passes through the bottom of the tub 1 and the bottom of the pulverizing container 22 (i.e., the bowl bottom of the bowl shape recess) and extends to a prescribed position inside the pulverizing container 22. The cutter head 21 is fixed near the first end 2311 of the driving shaft 231, and since the first end 2311 of the driving shaft 231 is located at a predetermined position in the pulverizing container 22, the distance between the cutter head 21 and the bottom of the pulverizing container 22 can be controlled by specially setting the predetermined position, thereby achieving a better cutting effect of the cutter head 21.

In practical applications, if the center of mass of the cutterhead 21 rotating at high speed does not coincide with the rotation center, a centrifugal force is generated, which generates exciting force to the driving shaft 231 to cause the body of the driving portion 23 to vibrate, and if the centrifugal force is too large, the vibration may even damage the structure of the driving portion 23. In order to solve the above problem, the centroid of the cutterhead 21 is provided with the mounting hole 211, that is, the mounting hole 211 coincides with the centroid of the cutterhead 21, and the first end 2311 of the driving shaft 231 may be nested in the mounting hole 211, so that the cutterhead 21 uses the driving shaft 231 as the rotation center, and thus the centroid of the cutterhead 21 coincides with the rotation center thereof, and further the unbalance of the cutterhead 21 is ensured to be in a qualified range.

It should be noted that a sealing member may be provided at a position where the driving shaft 231 contacts the bottom of the tub 1 and a position where the driving shaft 231 contacts the bottom of the pulverizing container 22, respectively, so as to prevent leakage of liquid or dust from the contact.

In one implementation, the crushing assembly 2 further includes a filter screen 24, where the filter screen 24 is disposed between the bowl bottom of the bowl-shaped concave shape and the cutter head 21, specifically, the filter screen 24 may be clamped on the inner wall of the crushing container 22, and the filter screen 24 may completely cover the bottom of the crushing container 22, so as to obtain the optimal filtering effect. To avoid the filter screen 24 from affecting the drive shaft 231 to rotate the cutterhead 21, the drive shaft 231 may penetrate the filter screen 24 and the drive shaft 231 may not contact the filter screen 24. In practical applications, small particles formed after cutting are mixed with liquid materials to form a solid-liquid mixture, and the solid-liquid mixture can be filtered by the filter screen 24, so that larger particles remain on the filter screen 24 to avoid the larger particles from blocking a sewer.

In order to stably fix the crushing assembly 2 inside the tub 1, in one embodiment, a limiting groove 15 is provided on an inner wall of the tub 1, and a clamping block 222 is provided on an outer edge of a top of the crushing container 22. The clamping block 222 is matched with the limiting groove 15 in shape, so that the clamping block 222 can be clamped inside the limiting groove 15, and the crushing container 22 is fixed inside the barrel body 1. To facilitate cleaning of the pulverizing container 22, in practical applications, the fixture block 222 may be movably installed in the limiting groove 15, so that the pulverizing container 22 is detachably connected to the inside of the tub 1. Thus, when the user needs to clean the pulverizing container 22, the user can conveniently take out the pulverizing container 22 from the inside of the tub 1.

Further, the limiting groove 15 may be annularly disposed along the inner wall of the barrel body 1, and the top outer edge of the crushing container 22 may be integrally bent downward to form a U-shaped structure, which may serve as the clamping block 222. When the pulverizing container 22 is placed inside the tub 1, the above-described U-shaped structure may be inserted into the limit groove 15, thereby hanging and fixing the pulverizing container 22 inside the tub 1.

It should be noted that the height of the limiting groove 15 on the inner wall of the tub 1 needs to be set with reference to the height of the pulverizing container 22, so as to ensure that when the pulverizing container 22 is fixed inside the tub 1, a preset distance exists between the bowl bottom of the bowl-shaped concave shape of the pulverizing container 22 and the bottom of the tub 1, and the preset distance can ensure that the liquid material and the solid-liquid mixture can flow freely to the water outlet pipeline 14. The above-mentioned preset interval may be set to be between 1cm and 5cm according to an empirical value.

Further, the water inlet of the water outlet pipeline 14 is located at the bottom of the tub 1, and the height of the tub at the position where the water inlet is located is lower than the height of other areas at the bottom of the tub 1, that is, the water inlet of the water outlet pipeline 14 is located at the lowest point at the bottom of the tub 1. In practical application, the bottom of the barrel body 1 can be constructed by using a curved surface, and a hole is formed at the lowest point of the curved surface to form a water inlet of the water outlet pipeline 14. The water inlet of the water outlet pipeline 14 is arranged at the lowest point of the bottom of the barrel body 1, so that all liquid materials or solid-liquid mixtures flowing out of the opening 221 on the crushing container 22 can be ensured to flow into the water outlet pipeline 14.

In one implementation, as shown in fig. 5, the cutterhead 21 includes a circular base 212 and a first cutting edge 213, wherein the circular base 212 is a metal body with uniform mass distribution, and the mounting hole 211 is located at the geometric center of the circular base 212, so as to ensure that the mounting hole 211 coincides with the center of mass of the circular base 212. The first cutting edge 213 horizontally extends from the outer edge of the circular base 212 to the radial outside of the circular base 212, and the first cutting edge 213 is formed outside the circular base 212 in a center-symmetrical manner. In other words, the first cutting edge 213 includes a first cutting portion 2131 and a second cutting portion 2132, wherein a root portion of the first cutting portion 2131 and a root portion of the second cutting portion 2132 are respectively connected to an outer edge of the circular base 212, and the first cutting portion 2131 and the second cutting portion 2132 are fixed to the circular base 212 in a straight manner with respect to the mounting hole 211 as a center of symmetry.

In practical applications, the first cutting portion 2131 and the second cutting portion 2132 may be fixed to the circular base 212 by a process such as caulking or welding, or the first cutting portion 2131, the second cutting portion 2132 and the circular base 212 may be manufactured as a single body by an integral forging technique. The symmetrical configuration of the first 2131 and second 2132 cutting portions also ensures that the center of mass of the cutterhead 21 remains coincident with the mounting holes 211 to avoid wobbling during high speed rotation of the cutterhead 21.

Preferably, the first cutting edge 213 has a substantially rectangular plate-like structure with cutting edges on both long sides, and in this embodiment, the first cutting edge 213 forms a cutting surface of the cutterhead 21. The first cutting edge 213 may cut the solid material in the comminution vessel 22 as the cutterhead 21 rotates. It should be noted that the distance that the first cutting edge 213 extends outwardly is limited by the diameter of the comminution vessel 22, and the length of the first cutting edge 213 may be slightly less than the diameter of the comminution vessel 22 to ensure a cutting footprint.

In one possible embodiment, the cutterhead 21 further includes a second cutting edge 214, wherein the second cutting edge 214 extends radially outward of the circular base 212 from the outer edge of the circular base 212, and the second cutting edge 214 extends outwardly a distance less than the distance the first cutting edge 213 extends outwardly, i.e., the length of the second cutting edge 214 is less than the length of the first cutting edge 213. Referring to the structure of the first cutting edge 213, the second cutting edge 214 is also formed on the outer side of the circular base 212 in a center symmetrical manner with the mounting hole 211 as a symmetry center, so as to prevent the wobble of the cutterhead 21 during high-speed rotation.

Preferably, the second cutting edge 214 has a substantially rectangular plate-like structure with cutting edges on both long sides, and in this embodiment, the first cutting edge 213 and the second cutting edge 214 together form the cutting surface of the cutterhead 21. By means of the first cutting edge 213 and the second cutting edge 214, the cutterhead 21, which rotates at high speed, can form two cutting rings of different diameters for sufficiently cutting the solid material in the comminution vessel 22.

Further, the second cutting edge 214 has a shank 2141 and a leading edge 2142, wherein the shank 2141 is connected to the outer edge of the circular base 212 and extends horizontally radially outward of the circular base 212. The front edge 2142 is disposed at an end of the shank 2141 away from the circular base 212, and a first dihedral angle exists at a connection point between the front edge 2142 and the shank 2141, that is, the front edge 2142 extends obliquely upward with the shank 2141 as a horizontal base line. With the first dihedral angle, when the cutter head 21 rotates at a high speed, the cutting surface formed by the front edge 2142 is higher than the cutting surface formed by the first cutting edge 213, so that the cutter head 21 can form two cutting surfaces with different heights, thereby cutting the solid material in the crushing container 22 in the three-dimensional space, and the crushing assembly 2 can obtain a better crushing effect.

In practical applications, in order to ensure dynamic balance when the cutterhead 21 rotates at high speed, a first included angle exists between the shank 2141 and the first cutting edge 213, the first included angle is set based on the mass and length of the first cutting edge 213 and the second cutting edge 214, and the calculation method thereof can refer to the prior art and is not described herein.

In one possible embodiment, the cutterhead 21 further includes a third cutting edge 215, wherein the third cutting edge 215 extends radially outward of the circular base 212 from the outer edge of the circular base 212, and the third cutting edge 215 extends outwardly a distance less than the distance the second cutting edge 214 extends outwardly, i.e., the length of the third cutting edge 215 is less than the length of the second cutting edge 214. Referring to the structure of the first cutting edge 213, the third cutting edge 215 is also formed on the outer side of the circular base 212 in a center symmetrical manner with the mounting hole 211 as a symmetry center, so as to prevent the wobble when the cutter head 21 rotates at a high speed.

Preferably, the third cutting edge 215 has an edge, and in this embodiment, the first cutting edge 213, the second cutting edge 214, and the third cutting edge 215 together form an edge surface of the cutterhead 21. By means of the first cutting edge 213, the second cutting edge 214 and the third cutting edge 215, the cutterhead 21, which rotates at high speed, can form three cutting rings of different diameters for sufficiently cutting the solid material in the comminution vessel 22.

Further, the third cutting edge 215 has a transition portion 2151 and a nose portion 2152, wherein the transition portion 2151 is connected to the outer edge of the circular base 212 and extends horizontally radially outward of the circular base 212. The tip 2152 is disposed at an end of the transition portion 2151 away from the circular base 212, and a second dihedral angle exists at a junction of the tip 2152 and the transition portion 2151, that is, the tip portion 2152 extends obliquely upward with the transition portion 2151 as a horizontal base line. With this second dihedral angle, when the cutterhead 21 rotates at high speed, the cutting surface formed by the cutting edge 2152 will be higher than the cutting surface of the first cutting edge 213. Meanwhile, since the length of the third cutting edge 215 is smaller than that of the second cutting edge 214, the cutting surface formed by the tip 2152 is also different from the cutting surface formed by the front edge 2142, and the plurality of cutting surfaces interact with each other, so that the solid material in the pulverizing container 22 can be sufficiently agitated and cut into finer particles.

In practical applications, in order to ensure dynamic balance when the cutterhead 21 rotates at high speed, a second included angle exists between the transition portion 2151 and the first cutting edge 213, the second included angle is set based on the mass and length of the first cutting edge 213, the second cutting edge 214 and the third cutting edge 215, and the calculation method thereof can refer to the prior art and will not be described herein.

Since the linear velocity is proportional to the diameter of the circle in uniform circular motion, the linear velocity of the cutterhead 21 is smaller near the mounting hole 211 than at the outer edge thereof, and this difference will result in the pressure near the mounting hole 211 being smaller than at the outer edge of the cutterhead 21, so that solid materials such as light hairs will converge toward the mounting hole 211 and wind around the driving shaft 231, which will reduce the crushing effect of the crushing assembly 2 and even cause the failure of the driving portion 23. To solve the above problem, in one possible embodiment, the front edge 2142 is substantially rectangular, the nose 2152 is substantially triangular, and the degree of the first dihedral angle is smaller than the degree of the second dihedral angle. In other words, the angle of the tip 2152 is greater than the angle of the front edge 2142, so that when the cutterhead 21 rotates at high speed, the first cutting edge 213, the front edge 2142, and the tip 2152 can form three concentric circular cutting surfaces of different heights. The cutting surface formed by the tip portion 2152 is closest to the mounting hole 211, and the dihedral angle of the tip portion 2152 is the largest, and it is a sharp triangle, so that the tip portion 2152 can sufficiently cut solid materials such as hairs that are gathered near the mounting hole 211. With the first cutting edge 213, the second cutting edge 214, and the third cutting edge 215, the cutterhead 21 can obtain a larger cutting area and prevent light garbage from collecting toward the center of the cutterhead 21.

In one possible embodiment, the shredder assembly 2 further includes a stationary blade 25, wherein the stationary blade 25 is secured below the cutter head 21 and as close as possible to the cutter head 21, and wherein the stationary blade 25 remains stationary as the cutter head 21 rotates. Specifically, the driving shaft 231 may penetrate the fixed blade 25, so that the fixed blade 25 is nested at the first end 2311 of the driving shaft 231, and a socket (not shown) such as a bearing is disposed between the fixed blade 25 and the driving shaft 231, which can isolate the influence of the driving shaft 231 on the fixed blade 25, so that the fixed blade 25 will not be displaced in the circumferential direction of the driving shaft 231 even if the driving shaft 231 rotates, i.e., the moving shaft 231 cannot rotate the fixed blade 25.

In practice, the stationary blade 25 may be constructed in a plate-like rectangular structure with cutting edges on both long sides. Thus, when the cutterhead 21 rotates, the area where the cutterhead 21 and the stator blades 25 meet (area a shown in fig. 2) will create a shearing effect, thereby better cutting the solid material in the comminution vessel 22.

The fixed vane 25 and the cutter head 21 are worn after relatively rotating for a long time, and the clearance between the cutter head 21 and the fixed vane 25 is increased due to the wear, so that the shearing effect between the cutter head 21 and the fixed vane 25 is reduced. To solve this problem, in one possible embodiment, an elastic support 26 may be provided above the cutterhead 21 or below the stator blade 25, and the elastic support 26 may apply a force to the cutterhead 21 or the stator blade 25, so that the gap between the cutterhead 21 and the stator blade 25 is kept constant.

For example, in one scenario, a volute spring may be provided above the cutterhead 21 to act as a resilient support 26, the volute spring being secured to the first end 2311 of the drive shaft 231 to continuously apply a force to the cutterhead 21 that is directed vertically downward to bring the cutterhead 21 and the stator blade 25 into close proximity. In this way, even if wear occurs between the stator blade 25 and the cutterhead 21, the cutterhead 21 moves towards the direction approaching the stator blade 25 under the action of the volute spring, and the movement can compensate the wear between the stator blade 25 and the cutterhead 21, so that the optimal distance is always kept between the stator blade 25 and the cutterhead 21.

Preferably, when the elastic support 26 is disposed above the cutterhead 21, the elastic support 26 may be disposed to rotate synchronously with the cutterhead 21 to reduce friction. If the elastic support 26 cannot rotate synchronously with the cutterhead 21, wear plates and other components can be added between the elastic support 26 and the cutterhead 21 to prolong the service life of the cutterhead 21.

It should be noted that the elastic support 26 may be an elastic rubber or elastic sheet, and the like, and the elastic support 26 may be disposed above the cutterhead 21 and below the fixed blade 25 at the same time, and the present application is not limited to the type and number of the elastic support 26.

In one possible embodiment, the edge face of the stator blade 25 faces the bottom of the comminution vessel 22 and the edge face of the cutterhead 21 faces away from the bottom of the comminution vessel 22, i.e., the edge face of the stator blade 25 faces in the opposite direction as the edge face of the cutterhead 21, to form a scissors structure. Further, the stator blade 25 may be slightly inclined to the cutterhead 21 so that the cutting edge of the cutterhead 21 may make line contact with the cutting edge of the stator blade 25 as the cutterhead 21 rotates, thereby achieving a better shearing effect.

Preferably, the stationary blade 25 is configured to: the fixed blade 25 is sleeved on the driving shaft 231 in a central symmetry manner with the rotation center of the driving shaft 231 as a symmetry center, and the length of the fixed blade is greater than that of the first cutting edge 213. When the cutter head 21 rotates at a high speed, the cutter head 21 drives the solid materials in the crushing container 22 to rotate at a high speed, and the solid materials rotating at a high speed can be cut by the cutting edge on the fixed blade 25 after impacting the fixed blade 25. In this way, under the combined action of the cutterhead 21 and the fixed blades 25, the solid material in the comminution vessel 22 can be cut as finely as possible into particles in order to avoid clogging the sewer.

The present application further provides a pulverizing assembly 2, where the pulverizing assembly 2 at least includes a circular base 212, a pulverizing container 22, and a driving part 23, the circular base 212 is disposed inside the pulverizing container 22, and the circular base 212 is provided with a mounting hole 211. The driving part 23 is located outside the pulverizing container 22, and a driving shaft 231 of the driving part 23 passes through the bottom of the pulverizing container 22 and is nested in the above-described mounting hole 211 such that the circular base 212 is centered on the driving shaft 231. The first cutting edge 213, the second cutting edge 214, and the third cutting edge 215 are uniformly distributed along the outer edge of the circular base 212, and the first cutting edge 213, the second cutting edge 214, and the third cutting edge 215 are formed outside the circular base 212 in a center-symmetrical manner with the mounting hole 211 as a center of symmetry, respectively.

Further, the second cutting edge 214 has a shank 2141 and a leading edge 2142, wherein the shank 2141 is connected to the outer edge of the circular base 212 and extends horizontally radially outward of the circular base 212. In order to ensure dynamic balance during high-speed rotation of the cutterhead 21, a first included angle exists between the shank 2141 and the first cutting edge 213, the first included angle is set based on the mass and length of the first cutting edge 213 and the second cutting edge 214, and the calculation method thereof may refer to the prior art and will not be described herein. The front edge 2142 is disposed at an end of the shank 2141 away from the circular base 212, and a first dihedral angle exists at a connection point between the front edge 2142 and the shank 2141, that is, the front edge 2142 extends obliquely upward with the shank 2141 as a horizontal base line.

Further, the third cutting edge 215 has a transition portion 2151 and a nose portion 2152, wherein the transition portion 2151 is connected to the outer edge of the circular base 212 and extends horizontally radially outward of the circular base 212. A second angle is formed between the transition 2151 and the first cutting edge 213, and the second angle is set based on the mass and length of the first, second, and third cutting edges 213, 214, 215 to ensure dynamic balance when the cutterhead 21 rotates at high speed. The tip 2152 is disposed at an end of the transition portion 2151 away from the circular base 212, and a second dihedral angle exists at a junction of the tip 2152 and the transition portion 2151, that is, the tip portion 2152 extends obliquely upward with the transition portion 2151 as a horizontal base line.

Further, the crushing assembly 2 further comprises a fixed blade 25, wherein the fixed blade 25 is fixed below the circular base 212, the driving shaft 231 penetrates the fixed blade 25, and a socket (not shown) such as a bearing is arranged between the fixed blade 25 and the driving shaft 231, and the socket can isolate the influence of the driving shaft 231 on the fixed blade 25 so that the fixed blade 25 cannot displace in the circumferential direction of the driving shaft 231.

Further, an elastic support 26 may be provided above the circular base 212 or below the stationary blade 25, and the elastic support 26 may apply a force to the circular base 212 or the stationary blade 25, so that a gap between the circular base 212 and the stationary blade 25 is maintained constant.

For the specific structures of the circular base 212, the pulverizing container 22, the driving part 23, the first cutting edge 213, the second cutting edge 214, the third cutting edge 215, the fixed blade 25, and the elastic support 26, reference is made to the contents of the above embodiments, and a detailed description thereof will be omitted.

The present application also provides a cleaning base station comprising a base (not shown) and a recovery device a, wherein the recovery device a is located inside the base, and the recovery device a comprises at least a tub 1 and a pulverizing assembly 2. The tub 1 has a negative pressure pipe 11, a first recovery passage 12, a second recovery passage 13, and a water outlet pipe 14. The first recovery passage 12 and the second recovery passage 13 may communicate with external devices (e.g., a dust box, a dust bag, a cleaning tray, a sewage bucket, etc.), thereby collecting materials in the external devices to the inside of the tub 1. The pulverizing assembly 2 is disposed inside the tub 1, and the pulverizing assembly 2 is located downstream of the first recovery passage 12 and the second recovery passage 13 while the pulverizing assembly 2 is located upstream of the water outlet pipe 14.

The negative pressure pipeline 11 is connected with a negative pressure device, the negative pressure device can be arranged in the base, when the negative pressure device works, the negative pressure device can pump out gas in the barrel body 1 through the negative pressure pipeline 11, and then negative pressure is generated in the barrel body 1, so that external materials can enter the barrel body 1 through the first recovery channel 12 or the second recovery channel 13, and further enter the crushing assembly 2. For convenience of description, the present application limits the first recovery passage 12 to be used for recovering solid materials such as dust, hair, etc., and the second recovery passage 13 to be used for recovering liquid materials such as sewage.

The crushing assembly 2 has a crushing function that can perform crushing operation on solid materials entering the inside of the crushing assembly 2. For example, the pulverizing unit 2 may perform the pulverizing operation of the above solid materials by using a roller-type pulverizing mechanism, a jaw-type pulverizing mechanism, a blade-type pulverizing mechanism, or the like. When the solid material is crushed by the crushing unit 2, it is formed into a large amount of fine particles, which can be mixed with the liquid material, and then flows out of the crushing unit 2 and finally discharged from the tub 1 through the water outlet pipe 14.

For the specific structure of the recovery device a, reference may be made to the content related to the above embodiment, and details are not repeated here.

The application also provides a recycling control method of the cleaning base station, which is executed by a control system in the cleaning base station. For the specific structure of the cleaning base station, reference may be made to the content related to the above embodiment, and details are not repeated here. The method comprises the following steps:

s101: and judging whether the first docking channel is successfully docked with the dust box of the host machine.

In this embodiment, after the host returns to the cleaning base station, the host may send a signal to the control system informing it of the purpose of returning to the cleaning base station. For example, the host may inform the cleaning station that it needs to be replenished with electrical energy, or inform the cleaning station that the solid waste collected in its dust box has reached a threshold value for cleaning.

After the control system receives the signal which is sent by the host and needs to clean the dust box, the control system can control the first docking channel to dock with the dust box in the host. In the process of docking the first docking channel with the dust box, the sensor in the first docking channel feeds back docking information to the control system, and the control system judges whether the first docking channel is correctly inserted into the dust box or not based on the docking information. For example, a micro switch is arranged at the joint of the first joint channel and the dust box, when the first joint channel is correctly inserted into the dust box, the micro switch is triggered, the micro switch feeds back an electric signal to the control system, and the control system can judge that the first joint channel is successfully jointed with the dust box based on the electric signal. It should be noted that the above-described micro-switches are only illustrative, and should not be construed as limiting the application, and that other sensors may be employed in practical applications.

S102: if the butt joint is successful, the opening and closing states of the negative pressure pipeline, the first recovery channel, the second recovery channel and the water outlet pipeline are controlled based on a preset crushing strategy.

In this embodiment, after the control system determines that the first docking channel has been successfully docked with the dust box, the control system may control the open/close states of the solenoid valve 111, the solenoid valve 121, the solenoid valve 131 and the solenoid valve 141 according to a preset pulverizing policy set by a user in advance, and further control the open/close states of the negative pressure pipeline 11, the first recovery channel 12, the second recovery channel 13 and the water outlet pipeline 14, so as to recover the solid garbage in the dust box and the liquid material in the cleaning tray into the barrel 1. For example, the control system may close the second recovery passage 13 and the water outlet passage 14, simultaneously open the negative pressure passage 11, the first recovery passage 12, and activate the negative pressure device, so that the solid waste in the dust box may be sucked into the first recovery passage 12 and then transferred to the inside of the tub 1.

S103: and detecting medium flow information in the first recovery channel and the second recovery channel, and controlling the working state of the crushing assembly based on the medium flow information.

In this embodiment, the control system may detect the medium flow information in the first recovery passage 12 and the second recovery passage 13 in real time. For example, the control system may monitor in real time the flow information of the solid waste fed back by the solid flow meter in the first recovery channel 12 and the flow information of the liquid medium fed back by the liquid flow meter in the second recovery channel 13.

After the control system obtains the medium flow information, the control system can determine whether the medium still flows in the first recovery channel 12 and the second recovery channel 13, and further determine whether the garbage in the dust box and the liquid material in the cleaning tray are completely transferred to the inside of the barrel body 1. For example, if the flow information of the solid waste fed back by the solid flow meter is close to zero, the control system may determine that the waste in the dust box has been completely transferred to the inside of the tank body 1, and the control system may turn off the negative pressure device, stop extracting the solid waste from the dust box, and perform the next operation. Specifically, the control system may activate the shredder assembly 2 to perform a shredding operation on the solid waste inside the bin 1. Of course, the control system may also close the first recovery channel 12 and open the second recovery channel 13 to transfer the liquid material in the cleaning tray to the inside of the tub 1, and then start the crushing assembly 2 to crush the solid garbage in the tub 1.

The control system controls the working state of the crushing assembly 2 based on the medium flow information, and can be performed in combination with a preset crushing strategy, and the preset crushing strategy can be divided into a dry crushing strategy and a wet crushing strategy. The preset pulverizing strategy will be described in detail.

In one possible embodiment, if the preset pulverizing strategy is a dry pulverizing strategy, the control system controlling the open/closed states of the negative pressure line 11, the first recovery passage 12, the second recovery passage 13, and the water outlet line 14 may include the steps of:

s201: and closing the second recovery channel and the water outlet pipeline, and opening the negative pressure pipeline and the first recovery channel so as to transfer the solid garbage in the dust box to the inside of the barrel body through the first recovery channel.

In the present embodiment, the control system may send signals to the solenoid valve 111, the solenoid valve 121, the solenoid valve 131 and the solenoid valve 141, set the solenoid valve 131 and the solenoid valve 141 to the closed state, and set the solenoid valve 111 and the solenoid valve 121 to the open state, thereby closing the second recovery passage 13 and the water outlet pipe 14, and opening the negative pressure pipe 11 and the first recovery passage 12. Then the control system starts a negative pressure device, and the negative pressure device pumps out the gas in the barrel body 1 through a negative pressure pipeline 11, so that negative pressure is generated in the barrel body 1. Under the effect of the pressure difference, the solid waste in the dust box is transferred to the inside of the barrel body 1 through the first recycling channel 12.

S202: and detecting flow information of the solid garbage in the first recovery channel, closing the negative pressure pipeline and the first recovery channel when the flow information of the solid garbage is smaller than a first threshold value, and starting the crushing assembly to crush the solid garbage in the barrel body.

In this embodiment, the control system may detect the flow rate information of the solid waste in the first recovery passage 12 using the solid flow meter, and when the flow rate information of the solid waste in the first recovery passage 12 is smaller than the first threshold value, the control system may determine that the waste in the dust box has been completely transferred to the inside of the tub 1. At this time, the control system may close the negative pressure device and close the negative pressure line 11 and the first recovery passage 12, and then activate the pulverizing assembly 2 to perform a pulverizing operation on the solid garbage inside the tub 1. In practical applications, the first threshold may be set according to an empirical value, for example, the first threshold may be set to 0.1cm3/s.

It should be noted that, in another embodiment, after the control system determines that the garbage in the dust box has been completely transferred to the inside of the tub 1, the control system may simply turn off the negative pressure device, maintain the opened state of the negative pressure line 11 and the first recovery passage 12, and then activate the pulverizing assembly 2 to perform the pulverizing operation on the solid garbage inside the tub 1.

The control system can control the working time of the crushing assembly 2 according to the flow information of the solid garbage. Specifically, the control system can estimate how much solid garbage is in total to get into the inside of the barrel body 1 based on the flow information of the solid garbage, and when the solid garbage entering into the inside of the barrel body 1 is more, the control system can control the crushing assembly 2 to work for a longer time so as to fully crush the solid garbage. If less solid waste enters the interior of the barrel body 1, the control system can control the crushing assembly 2 to work for a shorter time so as to reduce energy consumption. When the crushing assembly 2 stops working, the control system can open the water outlet pipeline 14, so that the crushed solid garbage can fall into the water outlet pipeline 14 and finally enter the external sewage drain pipeline.

In order to better drain the crushed solid waste into the external sewer, in one possible embodiment, the control system may flush the tub 1 with liquid. Specifically, after the crushing assembly 2 stops working, the control system can firstly determine whether the cleaning tray has liquid materials, if the control system determines that the cleaning tray has liquid materials, the control system can set the first recovery channel 12 and the water outlet pipeline 14 to be in a closed state, then open the negative pressure pipeline 11 and the second recovery channel 13, and start the negative pressure device, so that the liquid materials are recovered to the inside of the barrel body 1 through the second recovery channel 13.

If the control system judges that the liquid material does not exist in the cleaning tray, the control system can start the cleaning function to clean the host machine, and sewage generated in the cleaning process is collected in the cleaning tray. After the cleaning base station completes the cleaning operation of the host machine, the control system may set the first recovery passage 12 and the water outlet passage 14 to a closed state, then open the negative pressure passage 11 and the second recovery passage 13, and start the negative pressure device, thereby recovering the sewage in the cleaning tray to the inside of the tub 1 through the second recovery passage 13. Of course, the control system can also directly open the clean water electromagnetic valve instead of opening the cleaning function to supplement clean water in the tap water pipeline to the cleaning tray.

When the control system judges that all the liquid medium in the cleaning tray is transferred to the inside of the barrel body 1 based on the flow information of the liquid medium fed back by the liquid flowmeter in the second recovery channel 13, the control system can close the negative pressure device, and at this time, liquid materials and crushed solid garbage exist in the inside of the barrel body 1. The control system can detect the suspended matter content of the liquid material in the barrel body 1 by utilizing the photometer and judge whether the suspended matter content is smaller than a second threshold value. If the content of the suspended matters is smaller than the second threshold value, it indicates that the solid-liquid separation phenomenon in the barrel body 1 is serious, and at this time, the control system can start the crushing assembly 2 to stir the solid-liquid mixture in the barrel body 1. The rotating cutter head 21 can fully stir up the solid particles deposited at the bottom of the barrel body 1 and uniformly mix the liquid material and the solid particles. It should be noted that the second threshold may be set according to an empirical value, which is not limited by the present application.

When the crushing assembly 2 works for a certain period of time, the control system can close the negative pressure pipeline 11 and open the water outlet pipeline 14, so that the liquid material and the crushed solid garbage are discharged from the barrel body 1 through the water outlet pipeline 14.

The working principle of the recovery device a will be described in detail below in connection with a specific application scenario.

Application scenario one (taking sweeping robot as an example)

A new cleaning robot is purchased by Xiaoming, and the cleaning robot is provided with a cleaning base station to be matched with the cleaning base station. The cleaning base station has the functions of automatically cleaning the sweeping robot and automatically feeding and discharging water, so that the cleaning base station does not need to manually clean a dust box in the sweeping robot and also does not need to clean a sewage tank and a dust bucket in the base station.

The water inlet pipe of the base station is communicated with a water tap in a house, the water outlet pipeline of the base station is communicated with a sewer in the house, then a power supply is connected to the base station, the preparation work is completed completely, and then the floor sweeping robot is started to clean the floor of the living room. After the sweeping robot finishes the sweeping work, the sweeping robot returns to the base station and is in butt joint with the base station, and a dust collection pipe in the base station is in butt joint with a dust box in the sweeping robot to start dust collection work.

The base station controls the electromagnetic valves on the negative pressure pipeline and the first recovery channel to be opened, controls the electromagnetic valves on the second recovery channel and the water outlet pipeline to be closed, then starts the vacuum pump, and the vacuum pump pumps gas in the barrel body through the negative pressure pipeline so as to generate negative pressure in the barrel body, so that solid garbage such as melon seed shells, soybeans, dog grains, cat litter, hair, paper scraps in the dust box of the sweeping robot can be recovered into the barrel body through the first recovery channel.

After the base station detects that the dust flux in the first recovery channel is reduced, the base station judges that the garbage in the dust box is basically recovered. The base station will close the vacuum pump and start the crushing assembly, utilize the high-speed rotation of blade disc to smash the operation to the solid rubbish inside the staving. Meanwhile, the base station starts the cleaning function of the cleaning cloth tray, and the cleaning operation is carried out on the cleaning cloth tray at the bottom of the sweeping robot. When the washing operation is completed and the pulverizing operation is also completed, the base station stops the pulverizing assembly, closes the solenoid valve on the first recovery passage, opens the solenoid valve on the second recovery passage, and then starts the vacuum pump again to recover the sewage generated by the washing operation into the tub.

When the base station detects that the liquid flow in the second recovery channel is reduced, the base station judges that the sewage is basically recovered. The base station will close the vacuum pump and open the solenoid valve on the outlet pipe so that the sewage mixed with the fine particles can flow into the sewer through the outlet pipe. Since the garbage such as the hair, the melon seed shell and the like is crushed into fine particles, the problem that the sewer is blocked is solved, the base station also cleans the barrel body when sewage is recovered, and the barrel body is not required to be maintained by the Ming dynasty. The device can check whether the water supply and drainage of the base station are normal or not at regular intervals, and does not need other operations, so that the hands are actually known.

The foregoing description of the preferred embodiments of the application is not intended to limit the application to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the application are intended to be included within the scope of the application.
