Description

Technical Field

[0001] The utility model relates to the technical field of cleaning electrical appliances, in particular to a cleaning robot and a matching cleaning table. Background Art

[0002] There are still some common technical defects in the mopping function and garbage disposal of existing sweeping robots and floor scrubbers. The following is a summary of some of the main technical defects of existing sweeping robots and floor scrubbers:

[0003] 1. Most existing sweeping robots use two disc-shaped rotating mops to mop the floor, which results in a smaller area of ​​the mops in contact with the ground in the middle and on both sides of the two mops, resulting in uneven mopping effect.

[0004] 2. Existing cleaning robots, household floor scrubbers, electric mops and other cleaning appliances that use roller brushes to clean the floor all flush water outside the roller brushes during cleaning, which makes it difficult to clean the dirt at the root of the roller brushes, affecting the effect of mopping the floor.

[0005] 3. Most of the existing floor cleaning tools such as sweeping robots and household floor scrubbers leave some moisture on the floor after cleaning, which not only affects the cleaning effect but also may cause slips and falls to injure people.

[0006] 4. The existing household floor scrubbers are heavy to use because the suction fan, clean water box, sewage box and battery are all installed in the lower half of the handlebar, and generally cannot be put under furniture, which seriously affects the scope of use.

[0007] 5. Household floor scrubbers usually only have scrubbing roller brushes but no sweeping components, including side brushes, sweeping roller brushes and trash boxes. Not only can they not suck in larger garbage such as paper balls, but they also often cause blockage in the air intake port, making them very inconvenient to use.

[0008] 6. Some existing sweeping robots have adopted a method of setting up a temporary trash bin at the charging place, which can suck the garbage in the trash box of the sweeping robot into the temporary trash bin. However, after a period of time, the trash bin is full and manual disposal of the garbage is still required. Summary of the invention

[0009] In order to solve the above-mentioned problems and defects of the existing cleaning robots and supporting cleaning devices, the purpose of the utility model is to provide a cleaning robot and a supporting cleaning table with high mopping efficiency, wide application range, worry-free and labor-saving cleaning, and good mopping effect.

[0010] The utility model solves the above technical problems of existing cleaning robots by adopting a technical solution: the cleaning robot includes a cleaning robot frame component, an intelligent control walking component, a sweeping component, and a mopping component.

[0021] There are running wheels under the frame, the two front wheels are universal wheels, and the two rear wheels are driving wheels;

[0022] The cover is fixed on the frame to cover the entire components of the cleaning robot.

[0023] A further solution of the cleaning robot of the utility model is that a dust suction head is provided at the back of the garbage box, both ends of the dust suction head are fixed on the frame, the suction pipe of the dust suction head is connected with the air inlet hose of the sewage tank, and an auxiliary sweeping roller brush with its own motor is provided in the dust suction head.

[0024] A further solution of the cleaning robot of the utility model is that a small water suction scraper is provided behind the tray frame, and the air suction pipe of the small water suction scraper is connected to the air inlet area of ​​the sewage tank;

[0025] A sensor for sensing fluid waste is provided below the front facade of the cleaning robot, and the sensor is electrically connected to the intelligent controller. When the sensor senses fluid waste, the intelligent controller turns the cleaning robot around so that the small suction shovel head is in front to clean the fluid waste. After cleaning, the head is turned back to prevent the sweeping component from being stuck with fluid waste and being unable to continue cleaning the floor.

[0026] A further solution of the cleaning robot of the utility model is that a hot air blower with the same width as the mopping roller brush is provided at the rear of the frame. The upper half of the hot air blower is wider and is provided with a row of small fans inside. Below the small fans are electric heating elements such as ceramic heating plates. The hot air nozzle at the lower half is narrower and the hot air is blown out in a direction obliquely to the rear, which can dry the ground on the one hand and disinfect the ground at high temperature on the other.

[0027] A further solution of the cleaning robot of the utility model is that the garbage box has a movable bottom structure, the rear edge of the bottom of the garbage box is hinged to the lower edge of the rear vertical wall, and a vertically installed electric push rod is provided on the outside of one or two end faces of the garbage box, the motor end of the electric push rod is at the top, and the mounting hole of the motor end is hinged to the upper end of the end face of the garbage box through a rotating shaft; the telescopic end of the electric push rod is at the bottom, and its mounting hole is hinged to the rotating shaft on the end face of the bottom plate of the garbage box. When dumping garbage, the electric push rod extends to turn the bottom of the garbage box down, and after dumping the garbage, the electric push rod retracts to turn the bottom of the garbage box up and reset to close; the electric push rod is controlled by an intelligent controller.

[0028] In a further solution of the cleaning robot of the utility model, two parallel mopping roller brushes are arranged inside the water suction squeegee head, the rotating shafts of the two mopping roller brushes are both tubular rotating shafts, and a flushing mesh hole is arranged on the rotating shaft covered by the wiping cloth;

[0030] Clean water enters the water-permeable wiping cloth from the flushing mesh of the tubular shaft. The centrifugal force generated by the rotation of the mopping roller brush and the pressure of the water pump on the water can cause the clean water to be thrown out from the inside to the outside at high speed, thus flushing the mopping roller brush from the inside to the outside.

[0031] A sealed recess for placing a motor is provided in the tubular rotating shaft at the end of the mopping roller brush where the water inlet pipe is not installed. A gap for passing water is provided between the outer wall of the recess and the inner wall of the tubular rotating shaft. The motor is placed in the recess and fixedly connected to the inner wall of the recess. The motor shaft is fixed on the frame. The rotation of the motor housing drives the mopping roller brush to rotate.

[0032] A V-shaped scraper with a center gap is provided between the two mopping roller brushes. The rotation direction of the two mopping roller brushes in contact with the V-shaped scraper plate is downward. The two long sides of the V-shaped scraper plate scrape the mopping roller brushes respectively, so that the sewage scraped from the mopping roller brushes can quickly and completely separate from the mopping roller brushes, and then flow to the center gap. Finally, the sewage is brought into the sewage tank by the airflow coming up from the center gap.

[0033] A further solution of the cleaning robot of the utility model is that both ends of the water suction scraper head are provided with air intake control baffles for controlling the air intake, and both ends and the middle of the air intake control baffle are provided with an air inlet. The airflow coming in from the air inlets at both ends respectively takes away the sewage scraped up by the front and rear scraping strips of the corresponding water suction scraper head, and the middle air inlet takes away the sewage in the middle seam of the V-shaped scraper plate.

[0034] In a further solution of the cleaning robot of the utility model, a water filling pipe is provided at the upper end of the clean water tank, a one-way valve is provided on the water filling pipe to prevent the clean water from overflowing, the water filling pipe opens on the front facade of the cleaning robot, and the water filling port is in a trumpet shape;

[0035] A water level sensor is arranged in the clean water tank, and a water level sensor contact electrically connected to the water level sensor and a battery charging contact are arranged on the front facade of the cleaning robot, and the charging contact is electrically connected to the battery.

[0036] A further solution of the cleaning robot of the utility model is to remove the intelligent control component for controlling the walking of the cleaning robot, and to install a floor scrubber handle bar with a control switch on the rear end of the cleaning robot frame in a hinged manner, and to replace all the walking wheels with universal wheels, so that the cleaning robot is converted into a floor scrubber.

[0037] In a further solution of the cleaning robot of the utility model, the handle of the floor scrubber is a tubular structure, and the lower end of the handle rod of the floor scrubber is connected to the air outlet of the sewage tank through a suction hose;

[0038] A handheld vacuum cleaner is plugged into the upper port of the handle bar of the floor scrubber for air suction, and a control switch of the floor scrubber is installed at the upper end of the handle bar of the floor scrubber.

[0039] The clean water tank and the battery can also be relocated and installed at the lower part of the handle bar. Both of them are in the shape of a flat box, so that the height of the floor scrubber will not be increased when the handle bar is laid flat to clean the low space under the sofa.

[0040] The utility model solves the above-mentioned technical problems of the existing cleaning robot supporting cleaning device by adopting the technical solution: the cleaning table is used in conjunction with the cleaning robot, and is used for the cleaning robot to dump garbage, discharge sewage, add clean water, charge, and clean the mopping roller brush. The cleaning table is square, and a funnel-shaped structure is formed inside the cleaning table body corresponding to the bottom of the garbage box. The funnel mouth is larger than the bottom of the garbage box, so that all the garbage dumped from the garbage box can enter the funnel. A flushing pipe with a flushing hole is arranged around the upper edge of the funnel mouth, and the flushing pipe is connected to the tap water pipe.

[0041] At a place corresponding to the sewage discharge port below the cleaning robot, a trumpet-shaped water receiving nozzle is provided in the cleaning table body, and the lower end of the water receiving nozzle is connected to the funnel through a sewage pipe, so that the discharged sewage enters the funnel;

[0042] The flushing pipe can flush the garbage and sewage in the funnel downwards. The flushing pipe is equipped with a funnel flushing solenoid valve, which is controlled by the intelligent controller of the cleaning table. A garbage basket is provided at the lower end of the funnel. The garbage stays in the garbage basket, and the sewage enters the sewer through the sewage pipe.

[0043] A ramp is provided on one side of the cleaning table to enable the cleaning robot to climb onto the multifunctional cleaning table; the ramp has an anti-slip function; side baffles are provided on both sides of the ramp to prevent the cleaning robot from falling;

[0044] A functional wall is provided on one side opposite to the ramp, and wall panels are provided on the other two sides; the functional wall is provided with a smart controller for the washing table, a charger, and a water pipe; the outer facade of the functional wall is provided with a door for installation and maintenance;

[0045] A soap liquid box is arranged on the top surface of the functional wall and the enclosure wall, a soap liquid filling port is arranged on the top surface of the soap liquid box, and a soap liquid discharge pipe is arranged at the bottom of the soap liquid box;

[0046] A water filling nozzle matching the trumpet water filling port on the clean water tank of the cleaning robot is arranged on the inner side of the functional wall. The rear end of the water filling nozzle is connected to the tap water pipe and the soap liquid pipe through a three-way pipe fitting in the functional wall. The tap water pipe and the soap liquid pipe are respectively provided with a clean water solenoid valve and a soap liquid valve. The clean water solenoid valve and the soap liquid valve are electrically connected to the intelligent controller of the cleaning table. After the cleaning robot climbs onto the cleaning table, the water filling nozzle is just inserted into the trumpet water filling port of the clean water tank on the front facade of the cleaning robot. After the clean water tank is filled with water, a certain proportion of soap liquid is added.

[0047] The water level sensor contact on the inner side of the functional wall is electrically connected to the washing table intelligent controller in the functional wall backwards, and is electrically connected to the water level sensor contact on the front facade of the cleaning robot forwards. In this way, when the water in the clean water tank is full, the water level sensor closes the clean water solenoid valve in the functional wall through the washing table intelligent controller, and stops adding water to the clean water tank;

[0048] The charging contacts on the inner side of the functional wall are electrically connected to the charger inside the functional wall, and then connected and fitted with the charging contacts on the front side of the cleaning robot to charge the battery.

[0049] The surface of the cleaning table is a sloped surface that tilts toward the functional wall. With the help of the gravity of the cleaning robot sliding down, the water level sensor contact and the charging contact can be more tightly fitted.

[0050] After the cleaning robot climbs onto the cleaning table, it starts charging its battery;

[0051] At the same time, the mopping brush is cleaned while adding water to the clean water tank. The cleaning station intelligent controller controls the clean water tank pump and the mopping brush to stop rotating automatically after cleaning. Add water to the clean water tank and continue to clean the mopping brush. The cleaning process stops automatically after the tank is full.

[0052] At the same time, the onboard intelligent controller on the cleaning robot activates the electric push rod on the garbage box, causing the bottom plate of the garbage box to flip down to dump the garbage; at the same time, the onboard intelligent controller also opens the sewage discharge solenoid valve of the sewage tank to discharge the sewage; the garbage and sewage all fall into the funnel of the cleaning table, the garbage remains in the net basket and is dumped, and the sewage is discharged into the sewer;

[0053] After the garbage and sewage are discharged, the intelligent controller of the cleaning station opens the solenoid valve of the flushing pipe, and the flushing pipe on the upper edge of the funnel starts to flush water, and finally the inside of the cleaning station is rinsed clean.

[0054] A further solution of the cleaning robot cleaning device of the utility model is to provide a faucet heater on the water pipe between the back of the water adding nozzle and the clean water solenoid valve and the soap valve, so that the clean water and soap liquid coming out of the water adding nozzle are both hot water or hot soap liquid with stronger decontamination ability.

[0055] According to a further solution of the cleaning device of the cleaning robot of the utility model, a disinfection lamp is provided on the cleaning table to disinfect the sweeping component and the mopping component below the cleaning robot.

[0056] A further solution of the cleaning robot cleaning device of the utility model is that a grinder is installed under the funnel of the cleaning table, and all the garbage and sewage coming down from the lower port of the funnel directly enter the inlet of the grinder. After the garbage is ground into pulp by the grinder, it enters the sewer together with the sewage and is washed away;

[0057] The grinder is controlled by an intelligent controller on the cleaning table. When the cleaning robot reaches the cleaning table, the grinder starts and stops automatically after the garbage is processed.

[0058] A further solution of the cleaning robot cleaning device of the utility model is that a synchronous pulley is provided at the lower end of the grinder shaft, and a grinder driving motor with a matching synchronous pulley is provided, so that its synchronous pulley is fixedly installed side by side with the grinder below, and then the two synchronous pulleys are connected by a synchronous belt for transmission. The motor is controlled by an intelligent controller of the cleaning table, which can minimize the height of the grinder, thereby reducing the height of the cleaning table.

[0059] A further solution of the cleaning device of the cleaning robot of the utility model is that a rotating shaft is provided at the upper end of the ramp plate, and the rotating shaft is hinged to the edge of the cleaning table. After the cleaning robot climbs onto the cleaning table, the ramp plate is immediately flipped upwards, and the ramp plate is then used as an upper wall door panel to flip over and close the wall door. The ramp plate is both a passage for the cleaning robot to crawl onto the cleaning table and a door panel for the wall door.

[0060] In a further solution of the cleaning robot cleaning device of the utility model, a torsion spring for assisting the ramp plate to turn up is installed on the ramp plate rotating shaft;

[0061] A synchronous pulley is installed at one end of the ramp plate shaft, and a motor is installed under the cleaning table. The motor is equipped with a synchronous pulley matching the shaft synchronous pulley. The synchronous belt is driven by the motor to realize the up and down flipping of the ramp plate through the forward and reverse rotation of the motor.

[0062] A limit switch handle is provided on the rotating shaft of the ramp plate. An upward limit switch and a downward limit switch are provided at the position corresponding to the handle. When the ramp plate is turned over in place, the limit switch stops the motor from rotating.

[0063] A button switch is installed on the wall, and the button switch is electrically connected to the shaft drive motor. After the sweeping robot climbs onto the multifunctional cleaning table, the front face of the sweeping robot just presses the button switch, and the motor starts to rotate to flip the ramp upwards and close the wall door.

[0064] The fence door is equipped with a smart door lock, which can prevent theft when the cleaning robot is used in public places;

[0065] When the sweeping robot leaves the cleaning table and returns to the ground, the sweeping robot moves backward, the button switch pops up, and the motor starts to rotate to flip the ramp down and put it on the ground, allowing the sweeping robot to get off the cleaning table;

[0066] The button switch is electrically connected to the intelligent controller of the washing table. When the button switch is pressed, the intelligent controller of the washing table is also started at the same time. The intelligent controller of the washing table then starts the electric push rod under the garbage box to dump the garbage; opens the sewage discharge solenoid valve to discharge sewage, opens the clean water solenoid valve to add water to the clean water tank; opens the soap liquid solenoid valve to add soap liquid; starts the grinder to start grinding the garbage; finally, opens the funnel flushing solenoid valve to flush the funnel inside the washing table.

[0067] According to a further solution of the cleaning device of the cleaning robot of the utility model, after the cleaning robot is replaced with a floor scrubber, a slot for a handle bar of the floor scrubber is provided on the soap liquid box, and the handle bar can be inserted into the slot after being erected.

[0068] Compared with the prior art, the above technical solution has the following beneficial effects:

[0069] 1. The mopping assembly adopts the structure of two large-scale high-speed relative rotation mopping brushes, which greatly increases the mopping area and makes the mopping more uniform than the two disc mops used by general cleaning robots. The relative high-speed rotation of the two mopping brushes further enhances the mopping effect, and ordinary families can clean the whole house thoroughly in one go.

[0070] 2. Since the mopping roller adopts a tubular rotating shaft structure with mesh holes, the mopping roller flushes from the axis to the outside, which makes the mopping roller flush cleanly and thoroughly while saving water. This original structural design has taken the core technology of floor cleaning to a new level and reached a new height.

[0071] 3. Since the dust suction head is set behind the garbage box, not only can the sweeping component clean the dust more thoroughly, but also the cleaning robot can clean the carpeted floor. In this way, the cleaning robot can clean all types of floors such as carpets, tiles, and wooden floors.

[0072] 4. Because of the structure of setting a water suction squeegee head behind the mopping component, all the residual water on the ground is sucked into the sewage tank by the water suction squeegee head. The ground mopped by the cleaning robot is basically dry and no longer slippery, which completely avoids falls and injuries due to slippery ground.

[0073] 5. Because the mopping component is equipped with a floor-washing mopping roller brush and a water-squeegee head, it can wash the floors of kitchens and bathrooms, which completely changes the problem that ordinary sweeping robots cannot clean kitchens and bathrooms. The cleaning robot has a full range of complete floor cleaning functions for the whole house, which will greatly accelerate the popularization and application of cleaning robots.

[0074] 6. Due to the structure of the fluid sensor in front of the cleaning robot and the structure of the water suction squeegee head and the mopping roller brush in the mopping assembly, the cleaning robot can turn around when encountering fluid garbage, with the water suction squeegee head in front, first use the water suction squeegee head to suck the fluid garbage into the sewage tank, and then use the mopping roller brush to clean the floor. This unique and innovative design completely solves the problem that the sweeping robot cannot handle fluid garbage, which has been bothering people for a long time, and makes the sweeping robot technology take a big step forward.

[0075] 7. Due to the structure of arranging the hot air drying device at the rear of the cleaning robot, the floor or carpet cleaned by the cleaning robot can be made dry, and the floor can also be disinfected and sterilized.

[0076] 8. Due to the hinged structure between the bottom of the garbage box and the rear wall of the garbage box, and the electric push rod installed at the end of the garbage box, which is controlled by the intelligent controller, the bottom of the garbage box can be automatically flipped downward, thereby achieving the ideal effect of the cleaning robot automatically dumping garbage.

[0077] 9. Due to the arrangement of a sewage discharge solenoid valve at the bottom of the sewage tank, which is controlled by an intelligent controller, the cleaning robot can automatically discharge sewage.

[0078] 10. Since a one-way valve is provided on the water supply pipe of the clean water tank and a one-way valve is also provided at the water inlet of the sewage tank, the clean water and sewage inside will not overflow no matter how the cleaning robot moves and changes its posture, an ideal effect is achieved.

[0079] 11. By installing a garbage grinder at the sewage outlet of the cleaning table, the ground garbage and sewage are directly discharged into the sewer, which completely realizes the remarkable beneficial effect that the cleaning robot no longer needs to rely on manual labor to dump garbage and sewage and add clean water. All the tasks are completed by the cleaning robot alone, realizing the beautiful ideal that people have always expected that ground hygiene no longer needs to be managed by humans.

[0080] 12. A flushing pipe with flushing holes is arranged around the upper edge of the funnel of the washing table. The solenoid valve on the flushing pipe is controlled by the intelligent controller of the washing table. The garbage and sewage in the funnel can be flushed down at any time, achieving the ideal effect of keeping the inside of the washing table clean and preventing mold.

[0081] 13. When the cleaning robot is transformed into a floor scrubber, the clean water tank, sewage tank, vacuum fan and battery are all installed on the head of the floor scrubber, and no components are attached to the handle of the floor scrubber. This not only makes the handle of the floor scrubber lighter and more flexible, making it easier to clean the floor, but also because the size of the handle of the floor scrubber is reduced, it can clean the small places under the furniture.
