Water-saving dust-suction floor washing machine

Abstract

This invention relates to the field of floor scrubber technology and discloses a water-saving floor scrubber, including a scrubber handle. A scrubber housing is fixedly connected to the bottom end of the handle, and a connecting platform is fixedly connected to the bottom end of the housing. Side baffles are fixedly connected to both sides of the connecting platform. An arc-shaped scraper is fixedly connected to the side of the two side baffles closest to the scrubber handle, and a suction mechanism is fixedly connected to the side of the two side baffles furthest from the handle. When the invention moves, a rotating gear rotates, which in turn drives a reciprocating screw to rotate, causing a moving plate to move back and forth. The moving plate drives a filter scraper to move back and forth. When the filter scraper moves, it pushes impurities in the wastewater in the collection tank to the outside of two dividing blocks. The impurities cannot return to the center of the collection tank through the dividing blocks, allowing the water in the center of the collection tank to be reused, thus saving water and preventing blockages.

Description

Technical Field

[0001] This invention relates to the field of vacuum cleaners and floor scrubbers, and more specifically to a water-saving vacuum cleaner and floor scrubber. Background Technology

[0002] A floor scrubber is a cleaning machine suitable for cleaning hard floors while simultaneously drying wastewater and removing it from the site. Floor scrubbers have advantages such as being environmentally friendly, energy-saving, and highly efficient. Floor scrubbers are available in various types, including semi-automatic, fully automatic, walk-behind, and ride-on models. They are widely used in places with large hard floors, such as stations, docks, airports, workshops, warehouses, and schools.

[0003] Nowadays, floor scrubbers have added a vacuuming function, becoming vacuum scrubbers. Vacuum scrubbers are cleaning devices that integrate floor scrubbing and vacuuming. They combine the functions of a vacuum cleaner and a floor scrubber, and can complete cleaning and vacuuming tasks at the same time. Vacuum scrubbers can sweep and mop at the same time, and can effectively handle both dry and wet waste, greatly improving cleaning efficiency and reducing the complexity and time of cleaning work.

[0004] When a floor scrubber is working, it cleans the impurities on the ground. At this time, the impurities are sucked into the wastewater tank along with the wastewater. If the ground is dirty and contains a lot of impurities, it is easy to get clogged during the wastewater absorption process. Once a clog occurs, the wastewater cannot be absorbed, so the floor will have residual wastewater after the floor scrubber has worked and the ground cannot be cleaned properly.

[0005] When a floor scrubber is working, the front rollers rotate to clean and move the dirt on the floor, and the rear scraper scrapes away all the dirt. Sufficient water is also needed to ensure the cleaning effect, so a water filling mechanism needs to be added in front of the scraper. Therefore, traditional floor scrubbers waste a lot of water when they are working. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide a water-saving vacuum cleaner and floor scrubber to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a water-saving floor scrubber, comprising a scrubber handle, a scrubber housing fixedly connected to the bottom end of the scrubber handle, a connecting platform fixedly connected to the bottom end of the scrubber housing, side baffles fixedly connected to both sides of the connecting platform, an arc-shaped scraper fixedly connected to the side of the two side baffles near the scrubber handle, and a suction mechanism fixedly connected to the side of the two side baffles away from the scrubber handle, a cleaning roller movably connected to the side of the two side baffles near the suction mechanism, a brush roller movably connected to the side of the cleaning roller away from the suction mechanism, a collection mechanism movably connected to the side of the brush roller away from the cleaning roller, a water replenishment mechanism at the top of the collection mechanism, guide wheels movably connected to the side of the two side baffles away from the cleaning roller, a clean water tank fixedly connected to the top of the interior of the scrubber housing, and a wastewater tank fixedly connected to the bottom of the interior of the scrubber housing;

[0008] The collection mechanism includes a rotating gear, a reciprocating screw fixedly connected inside the rotating gear, collection grooves movably connected to both sides of the reciprocating screw, a movable plate threadedly connected to the side of the reciprocating screw, a partition block fixedly connected to both sides of the bottom end of the collection groove, both sides of the partition block being inclined surfaces, and a filter hole opened at the bottom end of the collection groove.

[0009] In a preferred embodiment, the water in the clean water tank is supplied to the cleaning roller through a clean water pipe. The arc-shaped scraper draws the sewage into the sewage tank. The sewage in the sewage tank is filtered and then enters the water replenishment mechanism. A connection channel is fixedly connected to the bottom of the floor scrubber housing. The connection channel connects the water replenishment mechanism and the arc-shaped scraper and connects the sewage to the sewage tank.

[0010] In a preferred embodiment, an output gear is fixedly connected to the side of the cleaning roller, a connecting gear meshes with the side of the output gear, and a rotating gear meshes with the side of the connecting gear away from the connecting gear. The side of the cleaning roller is in complete contact with the ground, the bristles on the side of the brush roller are in contact with the ground, and when the floor scrubber moves as a whole, the cleaning roller and the guide wheel rotate in the same direction.

[0011] In a preferred embodiment, fixed sleeves are fixedly connected to both sides of the bottom end of the movable plate, and filter scrapers are movably connected to the sides of the bottom ends of the two fixed sleeves. The filter scrapers have limiting holes inside that allow the fixed sleeves to move. A fixed rod is fixedly connected inside the limiting holes of the filter scrapers. A support spring is provided on the side of the fixed rod. The bottom end of the fixed sleeve has a limiting hole that matches the fixed rod. The side of the filter scraper has filter holes.

[0012] In a preferred embodiment, the water replenishment mechanism includes a drain channel that contains filtered wastewater from a wastewater tank. A sealing box is fixedly connected to the bottom end of the drain channel. A sealing plate is movably connected inside the sealing box. A magnetic plate is fixedly connected to the side of the sealing plate. An electromagnet is movably connected to the side of the magnetic plate away from the sealing plate. A water receiving channel is fixedly connected to the bottom end of the sealing box.

[0013] In a preferred embodiment, magnetic plates are fixedly connected to both sides of the sealed box, and a preload spring is movably connected inside the magnetic plate. The side of the preload spring away from the limiting block is fixedly connected to the side of the magnetic plate, and a limiting rod is provided on the side of the preload spring.

[0014] In a preferred embodiment, a water distribution tank is fixedly connected to the bottom end of the water receiving channel, and a preload spring is fixedly connected to the bottom end of the water distribution tank. The water distribution tank has an inclined groove inside, with the highest point in the middle and the lowest points at both ends of the inclined groove. Both the sealing plate and the sealing tank have through holes. When the magnetic plate is in contact with the electromagnet, the through holes of the sealing tank and the sealing plate are not connected, and the sealing plate seals the sealing tank.

[0015] The technical effects and advantages of this invention are as follows:

[0016] 1. When the present invention moves, the rotating gear rotates, which drives the reciprocating screw to rotate and causes the moving plate to move back and forth. The moving plate drives the filter scraper to move back and forth. When the filter scraper moves, it pushes the impurities in the wastewater in the collection tank to the outside of the two partition blocks. The impurities cannot return to the middle of the collection tank through the partition blocks. The water in the middle of the collection tank can be reused, which saves water. The impurities are collected to avoid clogging.

[0017] 2. The wastewater absorbed by this invention will enter the sewer channel after filtration. When the electromagnet is energized, a magnetic repulsion force is generated between it and the magnetic plate. At this time, the magnetic plate drives the sealing plate to move in the sealing box. The through hole of the sealing plate coincides with the through hole of the sealing box, and the wastewater is discharged to the front of the arc-shaped scraper. This ensures that the arc-shaped scraper has enough water for use and does not require a lot of purified water, thus saving water resources.

[0018] 3. This invention is equipped with a water outlet pipe, a water distribution tank, and a water receiving channel. When the filtered wastewater enters the water distribution tank through the sealing plate and the water receiving channel, the inside of the water distribution tank is inclined. Therefore, the water will flow down along the inclined surface inside the water distribution tank. Thus, the water in the water distribution tank can flow evenly down through the four water outlet pipes, avoiding the situation where the two inner water outlet pipes can carry water while the two outer water outlet pipes cannot carry water, which would cause partial water shortage.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The water-saving vacuum cleaner floor scrubber involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Reference Figure 1 , Figure 2 as well as Figure 3 This invention provides a water-saving floor scrubber, including a scrubber handle 1. A scrubber housing 2 is fixedly connected to the bottom of the handle 1. A connecting platform 3 is fixedly connected to the bottom of the housing 2. Side baffles 4 are fixedly connected to both sides of the connecting platform 3. Arc-shaped scrapers 5 are fixedly connected to the sides of the side baffles 4 closest to the handle 1. A suction mechanism 8 is fixedly connected to the sides of the side baffles 4 furthest from the handle 1. Cleaning rollers 9 are movably connected to the sides of the side baffles 4 closest to the suction mechanism 8. A brush roller 10 is movably connected to the sides of the cleaning rollers 9 furthest from the suction mechanism 8. A brush roller 10 is movably connected to the sides of the brush roller 10 furthest from the cleaning rollers 9. The collection mechanism 6 has a water replenishment mechanism 7 at its top. Guide wheels 12 are movably connected to the two side baffles 4 away from the cleaning rollers 9. A clean water tank 13 is fixedly connected to the top of the floor scrubber housing 2, and a wastewater tank 14 is fixedly connected to the bottom of the floor scrubber housing 2. The water in the clean water tank 13 is supplied to the cleaning rollers 9 through the clean water pipe 11. The arc-shaped scraper 5 sucks the wastewater into the wastewater tank 14. The wastewater in the wastewater tank 14 is filtered and then enters the water replenishment mechanism 7. A connection channel 201 is fixedly connected to the bottom of the floor scrubber housing 2. The connection channel 201 connects the water replenishment mechanism 7 and the arc-shaped scraper 5 and connects the wastewater to the wastewater tank 14.

[0032] In this embodiment, during operation, after the cleaning roller 9 and brush roller 10 have cleaned, the arc-shaped scraper 5 completes the final scraping work. During scraping, the arc-shaped scraper 5 will accumulate wastewater in its forward direction. Therefore, the suction holes provided in front of the arc-shaped scraper 5 will absorb the wastewater. The suction holes are as follows: Figure 2 As shown, after the arc-shaped scraper 5 absorbs water through the suction hole, it enters the wastewater tank 14 through the connecting channel 201. The water in the wastewater tank 14, after being filtered, also flows into the water replenishment mechanism 7 through the connecting channel 201, so that the wastewater can be circulated. In addition, it should be noted that the wastewater tank 14 is equipped with a filtration device, which is a common technical means for modern floor scrubbers. This application does not limit its structure in detail.

[0033] Reference Figure 4An output gear 401 is fixedly connected to the side of the cleaning roller 9. A connecting gear 402 meshes with the side of the output gear 401. A rotating gear 601 meshes with the side of the connecting gear 402 away from the connecting gear 402. The side of the cleaning roller 9 is in complete contact with the ground. The bristles on the side of the brush roller 10 are in contact with the ground. When the floor scrubber moves as a whole, the cleaning roller 9 and the guide wheel 12 rotate in the same direction.

[0034] In this embodiment, when the floor scrubber is working, the cleaning roller 9 is in complete contact with the ground. Therefore, the rotation direction of the cleaning roller 9 is the same as that of the guide wheel 12. The cleaning roller 9, through the output gear 401 and the connecting gear 402, causes the brush roller 10 to rotate in the opposite direction to the cleaning roller 9. Figure 4 In the reverse direction shown, the cleaning roller 9 rotates clockwise to clean the floor, and at the contact point between the cleaning roller 9 and the brush roller 10, water and impurities are thrown onto the side of the brush roller 10. The brush roller 10 rotates counterclockwise to collect the impurities and wastewater thrown out by the cleaning roller 9 on the floor. The brush roller 10 is in contact with the collection groove 603 in the collection mechanism 6, and the bristles of the brush roller 10 pass through the collection groove 603. Therefore, the wastewater and impurities on the brush roller 10 will enter the collection mechanism 6, enabling the floor to be cleaned more thoroughly. In addition, the cleaning roller 9 can also serve as a power output mechanism to ensure the smooth operation of the collection mechanism 6.

[0035] Reference Figure 5 , Figure 6 as well as Figure 7 The collection mechanism 6 includes a rotating gear 601, a reciprocating screw 602 fixedly connected inside the rotating gear 601, a collection groove 603 movably connected to both sides of the reciprocating screw 602, a moving plate 605 threadedly connected to the side of the reciprocating screw 602, a partition block 604 fixedly connected to both sides of the bottom end of the collection groove 603, both sides of the partition block 604 being inclined surfaces, a filter hole opened at the bottom end of the collection groove 603, a fixing sleeve 606 fixedly connected to both sides of the bottom end of the moving plate 605, a filter scraper 607 movably connected to the side of the bottom end of the two fixing sleeves 606, a limiting hole opened inside the filter scraper 607 allowing the fixing sleeve 606 to move, a fixing rod 608 fixedly connected inside the limiting hole of the filter scraper 607, a support spring 609 provided on the side of the fixing rod 608, a limiting hole adapted to the fixing rod 608 opened at the bottom end of the fixing sleeve 606, and a filter hole opened on the side of the filter scraper 607.

[0036] In this embodiment, after receiving wastewater and impurities in the collection tank 603, the reciprocating filter scraper 607 pushes the impurities to the other side of the separator block 604. When the filter scraper 607 passes the separator block 604, it moves upwards. As the filter scraper 607 moves upwards, the fixing rod 608 moves within the fixing sleeve 606. The bottom end of the fixing sleeve 606 compresses the fixing rod 608. Furthermore, when the top of the filter scraper 607 contacts the fixing sleeve 606, a seal is formed, preventing impurities from entering. The filter scraper 607 is inserted into the filter scraper 607, which causes the fixing rod 608 inside the filter scraper 607 to be locked. The filter holes opened on the side of the filter scraper 607 prevent water from being sent to the other side of the separator block 604 when the filter scraper 607 sends impurities, thus preventing impurities from flowing back into the collection tank 603. At this time, the sewage added below the collection tank 603 has been filtered and contains fewer impurities, which improves the working effect of the arc scraper 5 and does not waste clean water, thus saving water. The two sides of the collection tank 603 are fixed by the side baffles 4.

[0037] Referring to the figure, the water replenishment mechanism 7 includes a drain channel 708 that contains filtered wastewater from the wastewater tank 14. A sealing box 704 is fixedly connected to the bottom end of the drain channel 708. A sealing plate 705 is movably connected inside the sealing box 704. A magnetic plate 706 is fixedly connected to the side of the sealing plate 705. An electromagnet 707 is movably connected to the side of the magnetic plate 706 away from the sealing plate 705. A water receiving channel 703 is fixedly connected to the bottom end of the sealing box 704. Magnetic plates 706 are fixedly connected to both sides of the sealing box 704. A preload spring 711 is movably connected inside the magnetic plate 706. The preload spring 711 is located away from the water receiving channel 703. The side of the limiting block 709 is fixedly connected to the side of the magnetic plate 706. The side of the preload spring 711 is provided with a limiting rod 710. The bottom end of the water receiving channel 703 is fixedly connected to the water distribution tank 702. The bottom end of the water distribution tank 702 is fixedly connected to the preload spring 711. The water distribution tank 702 has an inclined groove inside, with the highest point in the middle and the lowest points at both ends of the inclined groove. Both the sealing plate 705 and the sealing box 704 have through holes. When the magnetic plate 706 contacts the electromagnet 707, the through holes of the sealing box 704 and the sealing plate 705 are not connected, and the sealing plate 705 seals the sealing box 704.

[0038] In this embodiment, when the filtered wastewater enters the drain channel 708, the sealing plate 705 seals the sealing box 704, preventing the wastewater from entering the water receiving channel 703 through the sealing box 704. When water needs to be added, the electromagnet 707 and the magnetic plate 706 generate magnetic repulsion, causing the magnetic plate 706 to move the sealing plate 705 within the sealing box 704. After the sealing plate 705 moves, the through hole of the sealing plate 705 coincides with the through hole of the sealing box 704, allowing the wastewater to enter the water distribution tank 702 through the water receiving channel 703. The filtered wastewater moves along the inclined surface within the water distribution tank 702 and then enters the four outlet pipes 701. The inclined surface ensures that the wastewater enters the four outlet pipes 701 relatively evenly. The four outlet pipes 701 discharge the wastewater to the front of the arc-shaped scraper 5, ensuring that the arc-shaped scraper 5 has sufficient water for use. The wastewater is filtered and reused, achieving a water-saving effect.

[0039] The working principle of this invention: When cleaning the floor, hold the floor scrubber handle 1 to move the entire device. The guide wheels 12 provide guidance, the suction mechanism 8 at the front absorbs impurities on the floor, the cleaning rollers 9 contact the floor and rotate, and the water pipe 11 adds clean water to the cleaning rollers 9. At this time, the cleaning rollers 9... Figure 2 The displayed perspective is a counter-clockwise rotation. The counter-clockwise rotation of the cleaning roller 9 drives the connecting gear 402 and the brush roller 10 to rotate clockwise through the output gear 401. When the cleaning roller 9 rotates counter-clockwise, it cleans up stubborn impurities on the ground. At the side where the cleaning roller 9 and the brush roller 10 are close together, the cleaning roller 9 rotates upward, throwing impurities and water onto the side of the brush roller 10. The brush roller 10 receives the water and impurities thrown out by the cleaning roller 9 and rotates again. At the contact point between the brush roller 10 and the collection tank 603, the collection tank 603 rotates downward relative to the contact point of the brush roller 10. Therefore, when the brush roller 10 passes the side wall of the collection tank 603, it will scrape the surface water and impurities into the collection tank 603.

[0040] When the rotating gear 601 rotates, it drives the connecting gear 402 to rotate. The rotation of the rotating gear 601 drives the reciprocating screw 602 to rotate. The rotation of the reciprocating screw 602 causes the moving plate 605 on its side to reciprocate. During this reciprocating movement, the moving plate 605 drives the filter scraper 607 to reciprocate via the fixed sleeve 606. The filter scraper 607 pushes impurities in the collection tank 603 to both sides of the collection tank 603. When the filter scraper 607 passes the separator block 604, it moves upward and compresses the support spring 609. Therefore... When the filter scraper 607 passes the top of the separator 604, it pushes the impurities on the side of the filter scraper 607 into the space between the other side of the separator 604 and the side of the collection tank 603. At this time, the filter scraper 607 will move in the opposite direction. The impurities that have entered the space between the separator 604 and the side of the collection tank 603 cannot pass through the separator 604. The impurities will accumulate on both sides of the collection tank 603 and cannot pass through the separator 604. When the filter scraper 607 resets and moves away from the location of the separator 604, the fixing rod 608 resets the filter scraper 607 and pushes the impurities to the other side.

[0041] When the impurities inside the collection tank 603 are pushed to both sides of the collection tank 603, the sewage in the collection tank 603 flows to the ground after being filtered at the bottom of the collection tank 603. The arc-shaped scraper 5 moves forward to scrape away the impurities and sewage on the ground, and the water suction holes on the side of the arc-shaped scraper 5 will suck the sewage and impurities into the sewage tank 14. After being filtered in the sewage tank 14, it flows into the drain channel 708. When the electromagnet 707 is energized, a magnetic repulsion force is generated between it and the magnetic plate 706, which causes the magnetic plate 706 to move... The dynamic sealing plate 705 moves within the sealing box 704. After the sealing plate 705 moves, the through hole of the sealing plate 705 coincides with the through hole of the sealing box 704. Therefore, the sewage will enter the water distribution tank 702 through the water inlet channel 703. After being filtered, the sewage moves on the inclined surface within the water distribution tank 702 and enters the four water outlet pipes 701. The sewage is discharged to the front of the arc-shaped scraper 5 through the four water outlet pipes 701, ensuring that the arc-shaped scraper 5 has enough water for use. The sewage will be filtered and reused.

[0042] In conclusion, the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
