A robotic vacuum cleaner with independent mop cleaning system

Abstract

This utility model relates to the field of sweeping robot technology, specifically a sweeping robot with an independent mop cleaning system. It includes a slot on the bottom of the robot body, a cleaning box detachably connected to the slot, and a cleaning mechanism slidably engaged with the cleaning box. The cleaning mechanism includes a U-shaped plate, with support arms rotatably connected to both arms of the U-shaped plate. In this utility model, starting a drive motor drives a rotating shaft to rotate, which in turn drives a rotating drum to rotate synchronously via a drive gear and a gear ring. The rotating shaft can also drive a rotating plate to rotate via a bevel gear, causing the rotating plate to slide back and forth on two fixed tubes via a guide rod, thereby improving the cleaning effect on the floor. Starting the drive motor uses a screw to retract the rotating drum into the cleaning box. Water is injected into the cleaning box through a water tank, and the drive motor drives the rotating drum to rotate while simultaneously sliding back and forth on the fixed tubes, causing the cleaning cloth to be combed by the protruding rod-like structure inside the cleaning box, thereby improving the cleaning effect on the cleaning cloth.

Description

Technical Field

[0001] This utility model relates to the field of sweeping robot technology, specifically a sweeping robot with an independent mop cleaning system. Background Technology

[0002] Robotic vacuum cleaners typically have a mop at the bottom to clean the floor. However, conventional robotic vacuum cleaners struggle to clean the mop, causing it to become dirty and easily contaminate other parts of the floor as the robot moves. The robot needs to return to its base station to clean the mop. Some existing robotic vacuum cleaners have independent mop cleaning systems with clean water and dirty water tanks. They use a roller brush to clean the floor, carrying dirt to the dirty water tank, and then spraying clean water from the clean water tank to rinse the roller brush, keeping it relatively clean. However, because the roller brush has bristles and is constantly in contact with the floor, the part of the brush between the dirty water tank and the clean water spray point remains dirty. The dirty bristles are prone to spreading the absorbed wastewater due to the material's absorbency and capillary action, easily contaminating the cleaned bristles. This makes cleaning the entire roller brush difficult and inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a robotic vacuum cleaner with an independent mop cleaning system to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A robotic vacuum cleaner with an independent mop cleaning system includes:

[0006] The robot body comprises a cleaning box for storing a cleaning cloth and a cleaning mechanism that can be dragged on the ground. The bottom of the robot body has a slot, into which the cleaning box is detachably connected. The cleaning mechanism is slidably engaged with the cleaning box. The cleaning mechanism includes a U-shaped plate, with support arms rotatably connected to both arms. The cleaning box has sliding grooves on its two opposite inner sidewalls, and each support arm has a protrusion fixedly connected to one end, which slidably engages with the two sliding grooves. The other ends of each support arm are fixedly connected to a fixing tube, and a rotating cylinder is positioned between the two support arms. Both ends of the rotating cylinder are rotatably fitted with collars, which slidably engage with the outer walls of the two fixing tubes. A cleaning cloth is detachably connected to the outer wall of the rotating cylinder.

[0007] Furthermore, a cover plate is rotatably connected to the top of the opening on one side of the cleaning box, and a torsion spring is provided at both ends of the cover plate. One end of each torsion spring is fixedly connected to the end of the adjacent cover plate, and the other end is fixedly connected to one side of the cleaning box. An L-shaped abutment plate is fixedly connected to the top surface of the U-shaped plate for opening the cover plate. A torsion spring is provided at one end of each arm. One end of each torsion spring is fixedly connected to one end of the adjacent arm, and the other end is fixedly connected to the side wall of the adjacent U-shaped plate.

[0008] Furthermore, the bottom surface of the cleaning box has a rectangular hole, and a box body is fixedly fitted inside the rectangular hole. A motor box is installed inside the box body, and a drive motor is installed inside the motor box. The motor shaft of the drive motor is fixedly connected to a screw. A threaded hole is opened on one side of the U-shaped plate, and the screw is screwed into the threaded hole.

[0009] Furthermore, a battery box is fixedly connected to a motor box, and a drive motor is installed inside the motor box. The motor end of the drive motor is rotatably connected to a rotating shaft, and the rotating shaft is rotatably connected to one end of another battery box. A drive gear is fixedly sleeved on the outer wall of the rotating shaft, and a gear ring is fixedly sleeved on the inner wall of the rotating cylinder, and the drive gear meshes with the gear ring.

[0010] Furthermore, a fixing plate is fixedly connected to the bottom surface of another battery box, and a sleeve hole is opened on the top surface of the fixing plate. A rotating plate is rotatably sleeved inside the sleeve hole, and a sliding hole is opened at the outer circumference of the top surface of the rotating plate. A guide rod is slidably sleeved inside the sliding hole. An annular groove is opened on the inner side wall of the rotating cylinder, and the bottom end of the guide rod is slidably engaged inside the annular groove. A bevel gear is fixedly connected to both the rotating shaft and the center of the top surface of the rotating plate, and the two bevel gears mesh with each other.

[0011] Furthermore, a connecting cylinder is fixedly connected to the top surface of the rotating plate, and a rebound spring is fixedly connected between the top surface of the connecting cylinder and the guide rod.

[0012] Furthermore, the robot body has two detachable water tanks on its top, each tank is equipped with a water pump, and each tank is connected to the cleaning box via a hose.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By starting the drive motor, the rotating shaft is driven to rotate, which in turn drives the rotating drum to rotate synchronously through the drive gear and gear ring. The rotating drum scrapes the ground with the cleaning cloth. The rotating shaft can also drive the rotating plate to rotate through the bevel gear. The rotating plate, through the guide rod, drives the rotating drum to slide back and forth on two fixed tubes, thereby improving the cleaning effect on the ground. Furthermore, by starting the drive motor, the screw can be used to pull the U-shaped plate and the rotating drum into the cleaning box. The cover plate automatically closes the cleaning box due to the torsion spring. Then, clean water is injected into the cleaning box through the water tank, and the drive motor drives the rotating drum to rotate and slide back and forth on the fixed tubes at the same time. This causes the cleaning cloth to be combed by the convex rod-shaped structure inside the cleaning box, thereby improving the cleaning effect on the cleaning cloth. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 In this embodiment of the present invention, a sweeping robot with an independent mop cleaning system includes:

[0024] The robot body 100, the cleaning box 200 which can hold the cleaning cloth 443, and the cleaning mechanism 400 which can be dragged on the ground are provided. The bottom surface of the robot body 100 has a slot 101. The cleaning box 200 is detachably connected to the slot 101. The cleaning mechanism 400 is slidably engaged with the cleaning box 200. The cleaning mechanism 400 includes a U-shaped plate 410, and both arms of the U-shaped plate 410 are rotatably connected to support arms 420. The two opposite inner sidewalls of the cleaning box 200 are provided with sliding grooves. One end of each of the two support arms 420 is fixedly connected to a protrusion. The two protrusions are slidably engaged in the two sliding grooves. The other end of each of the two support arms 420 is fixedly connected to a fixing tube 430. A rotating cylinder 440 is provided between the two support arms 420. Both ends of the rotating cylinder 440 are rotatably sleeved with collars 441. The inside of each of the two collars 441 is slidably sleeved with the outer sidewall of the two fixing tubes 430. The outer sidewall of the rotating cylinder 440 is detachably connected to the cleaning cloth 443.

[0025] Specifically, the cleaning box 200 is fixed inside the slot 101. One side of the cleaning cloth 443 is a Velcro surface, and the outer wall of the rotating drum 440 is covered with Velcro hooks. The cleaning cloth 443 can be quickly attached and detached using the Velcro. When mopping is needed, the U-shaped plate 410 is moved, causing the two support arms 420 to slide along the groove, thereby removing the rotating drum 440 and the cleaning cloth 443 from the cleaning box 200. Then, the rotating drum 440 naturally swings down, causing the cleaning cloth 443 to contact the ground, thus rolling and dragging it on the ground. During rolling, the rotating drum 440 is moved back and forth. The two collars 441 slide back and forth on the adjacent fixed pipes 430 to improve the cleaning effect on the ground. When the cleaning cloth 443 needs to be cleaned, the rotating drum 440 can be moved into the cleaning box 200 by moving the U-shaped plate 410. Then, water is filled into the cleaning box 200. The top and bottom surfaces of the cleaning box 200 are provided with protruding rod-like structures. By rotating the rotating drum 440 and sliding it back and forth, the fibers on the cleaning cloth 443 are combed by the protruding rod-like structures, so that the cleaning cloth 443 can be completely immersed in water for brushing, thereby improving the cleaning effect of the cleaning cloth 443. Example 1

[0026] like Figure 1As shown, in this embodiment, a cover plate 220 is rotatably connected to the top of the opening on one side of the cleaning box 200, and a torsion spring is provided at both ends of the cover plate 220. One end of each torsion spring is fixedly connected to the end of the adjacent cover plate 220, and the other end is fixedly connected to one side of the cleaning box 200. An L-shaped abutment plate 411 is fixedly connected to the top surface of the U-shaped plate 410 for opening the cover plate 220. A torsion spring is provided at one end of each arm 420. One end of each torsion spring is fixedly connected to one end of the adjacent arm 420, and the other end is fixedly connected to the side wall of the adjacent U-shaped plate 410. A rectangular hole is opened on the bottom surface of the cleaning box 200, and a box body is fixedly fitted inside the rectangular hole. A motor box 210 is provided inside the box body, and a drive motor is provided inside the motor box 210. A screw 211 is fixedly connected to the motor shaft of the drive motor. A threaded hole is opened on one side of the U-shaped plate 410, and the screw 211 is screwed into the threaded hole.

[0027] In this embodiment, starting the drive motor can drive the screw 211 to rotate, causing the screw 211 to move the U-shaped plate 410. When the rotating drum 440 is drawn into the cleaning box 200, the cover plate 220 naturally covers the opening of the cleaning box 200 due to the return force of the torsion spring. Both the cover plate 220 and the opening of the cleaning box 200 have a rubber coating, so that when the cover plate 220 covers the opening of the cleaning box 200, it can seal the cleaning box 200 and prevent water from leaking out of the cleaning box 200. When the U-shaped plate 410 moves and the rotating drum 440 moves out of the cleaning box 200, the abutment plate 411 can abut against the cover plate 220 after it is opened and support the cover plate 220 to prevent the cover plate 220 from naturally returning to its original position. Then, the two support arms 420 can press the rotating drum 440 and the cleaning cloth 443 onto the ground due to the return force of the adjacent torsion spring, so that the cleaning cloth 443 is in close contact with the ground.

[0028] like Figure 4-6 As shown, in this embodiment, a battery box 431 is fixedly connected to a motor box 450, and a drive motor is installed inside the motor box 450. The motor end of the drive motor is rotatably connected to a rotating shaft, and the rotating shaft is rotatably connected to one end of another battery box 431. A drive gear 451 is fixedly sleeved on the outer wall of the rotating shaft, and a gear ring 442 is fixedly sleeved on the inner wall of the rotating cylinder 440. The drive gear 451 and the gear ring 442 mesh with each other. A fixing plate is fixedly connected to the bottom surface of the other battery box 431, and a sleeve hole is opened on the top surface of the fixing plate. A rotating plate 460 is rotatably fitted inside the sleeve hole, and a sliding hole is provided at the outer ring edge of the top surface of the rotating plate 460. A guide rod 461 is slidably fitted inside the sliding hole. An annular groove is provided on the inner side wall of the rotating cylinder 440, and the bottom end of the guide rod 461 is slidably engaged inside the annular groove. A bevel gear 401 is fixedly connected to both the rotating shaft and the center of the top surface of the rotating plate 460, and the two bevel gears 401 mesh with each other. A connecting cylinder 462 is fixedly connected to the top surface of the rotating plate 460, and a spring 463 is fixedly connected between the inner top surface of the connecting cylinder 462 and the guide rod 461.

[0029] In practice, the battery box 431 contains a rechargeable battery, and each of the two support arms 420 has a circular hole at its other end for charging the rechargeable battery. During use, the circular holes can be sealed with rubber stoppers or other sealing materials to prevent water from entering the fixed pipe 430 inside the cleaning box 200. The rechargeable battery powers the drive motor. When the drive motor starts, it rotates the shaft, which in turn drives the rotating drum 440 to rotate via the drive gear 451 and gear ring 442. This rotation of the drum 440 utilizes the cleaning cloth 443 to scrape the ground, improving the cleaning effect. Furthermore, the rotation of the shaft can be further enhanced by the two bevel gears 401 driving the rotating drum 440 to rotate. The plate 460 rotates, causing the rotating plate 460 to slide back and forth on the two fixed tubes 430 through the guide rod 461 and the annular groove. The guide rod 461 can always be stuck inside the annular groove due to the resistance of the return spring 463. The contact surfaces of the two collars 441 with the rotating tube 440 and the fixed tubes 430 are all made of rubber, so that the collars 441 and the rotating tube 440 and the collars 441 and the fixed tubes 430 are in a sealed state, preventing water from entering the interior of the rotating tube 440. The fixed tubes 430 can be made of a material with low friction with rubber, so that the collars 441 can slide on the fixed tubes 430. Example 2

[0030] Based on Example 1, a water tank 300 is provided to facilitate the filling of water into the cleaning box 200.

[0031] like Figure 5 As shown, in this embodiment, the top of the robot body 100 is detachably connected to two water tanks 300. Each water tank 300 is equipped with a water pump, and the interior of each water tank 300 is connected to the interior of the cleaning box 200 through a hose.

[0032] In practice, the two water tanks 300 can respectively draw water from the cleaning box 200 or inject water into the cleaning box 200 using internal water pumps, so that the two water tanks 300 can respectively hold clean water and wastewater after cleaning the cleaning cloth 443, thus making it convenient for users to use.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
