Description

Technical Field

[0001] The invention belongs to the technical field of water surface cleaning equipment and relates to a water surface cleaning robot. Background Art

[0002] High-end hotels are generally equipped with public swimming pools. With the improvement of living standards, more and more private swimming pools are also installed in private homes. The biggest difficulty in swimming pools is cleaning the garbage. Currently, there are few devices on the market for cleaning floating garbage on the water surface. Usually, manual salvage is used to remove the garbage, which is time-consuming and labor-intensive. Therefore, water surface cleaning robots have emerged. For example, the roller brush of a water surface cleaning robot with the patent number 202322785915.5 published in China is driven by a motor that rotates and drives the meshing transmission gear to rotate. Since the transmission gear is fixedly connected to the clamping part, it will drive the roller brush to rotate together. Since the roller brush is set above the baffle and located at the opening of the storage basket, the blades on the roller brush will shovel the garbage that the robot passes through from the opening of the storage basket into the storage basket. Due to the blocking effect of the baffle, the garbage collected in the storage basket will no longer fall out of the storage basket, achieving the function of cleaning the garbage on the water surface. Because the roller brush is an integrated structure, the clips at both ends of the roller brush are hingedly connected through the mounting holes in the housing, allowing the roller brush to rotate on the robot housing. The motor then drives the transmission gear, which is fixedly connected to the clips, achieving the purpose of the motor-driven roller brush rotation. Because the roller brush can become entangled with debris during rotation, it needs to be removed for cleaning. However, the above structure makes it very inconvenient to remove the roller brush. First, the motor must be removed to separate the transmission gear, and then the roller brush must be moved horizontally to one side of the motor to disengage the clips on the other side from the mounting hole before the roller brush can be removed. To achieve this, the roller brush mounting structure needs to be redesigned. Summary of the Invention

[0003] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a water surface cleaning robot, which is equipped with a locking assembly for the roller brush mechanism, and can quickly remove the roller brush plate from the frame without disassembling the drive assembly.

[0004] The object of the present invention can be achieved by the following technical solutions: A water surface cleaning robot, comprising a frame, a storage mechanism, a roller brush mechanism and a travel mechanism, characterized in that the frame is provided with a through slot extending front to back, the roller brush mechanism is arranged at the front end of the through slot, the storage mechanism is arranged in the middle of the through slot, and the travel mechanism is arranged at the rear end of the through slot;

[0005] The storage mechanism includes a storage basket that slides back and forth along the through slot, and a switch assembly that can lock and unlock the position of the storage basket and the rack. The storage basket has two side panels and a front baffle with a hollow interior. The upper end of the storage basket is rotatably connected to an upper cover, and the switch assembly is located in the front baffle.

[0006] The roller brush mechanism includes a driving assembly, a roller brush plate, a core shaft, a positioning sleeve and an end cover. The driving assembly is fixed on one side of the frame, and a mounting cylinder is provided on the other side of the frame. The positioning sleeve is embedded in the mounting cylinder and fixed to the mounting cylinder. Several roller brush plates are sleeved on the core shaft and rotate synchronously with the core shaft. One end of the core shaft is dynamically connected to the driving assembly, and the other end of the core shaft is rotationally connected to the inner end of the positioning sleeve through a bearing. A locking assembly is provided between the outer end of the positioning sleeve and the end cover, which can quickly connect and separate the two.

[0007] The traveling mechanism drives the entire water surface cleaning robot forward on the water surface, collecting garbage floating on the water surface. The roller brush mechanism actively pushes leaves, branches and other debris into the through groove. Finally, the garbage is concentrated in the storage basket of the storage mechanism. The storage basket is pulled out from the through groove, and after cleaning the garbage inside, it is inserted back for continued use.

[0008] Furthermore, the frame has a limit baffle located in the through groove and capable of preventing the storage basket from continuing to slide backward. The groove wall of the through groove is provided with a track groove 1 and a track groove 2. The outer sides of the two side panels are provided with a slider and a sliding shaft. The slider can be embedded in the track groove 1 and slide along the track groove 1. The sliding shaft can be embedded in the track groove 2 and slide along the track groove 2. The track groove 1 is provided with a positioning groove 1. The lower end of the slider has a positioning point that is inserted into the positioning groove 1. The track groove 2 is provided with a positioning groove 2. When the positioning point is inserted into the positioning groove 1, the sliding shaft just falls into the positioning groove 2.

[0009] The storage basket slides along the wall of the through groove. When the storage basket slides to a position against the limit baffle, the positioning point is inserted into the first positioning groove and the sliding shaft is inserted into the second positioning groove, thereby achieving preliminary positioning of the storage basket.

[0010] Furthermore, the switch assembly includes a knob rotatably connected to the front baffle and two movable pins, a lock hole for the movable pin to be inserted is opened on the groove wall, and movable holes for the outer ends of the movable pins to pass through are opened on both sides of the front baffle, the inner end of the movable pin is eccentrically hinged to the knob and the movable pin can be inserted into the lock hole by rotating the knob, an unlocking groove and a locking groove are opened on the side of the knob, and a convex strip for being inserted into the unlocking groove or the locking groove is provided in the front baffle.

[0011] Turning the knob extends the movable pin out of the front panel or retracts it into the front panel. When the outer end of the movable pin is inserted into the lock hole, the storage basket and the rack are completely locked and no longer slide relative to each other. The ridges are used to position the knob to prevent it from rotating at will.

[0012] Furthermore, as another scheme, the switch assembly includes a pressing plate, a protective cover and two movable pin shafts, a lock hole for inserting the movable pin shafts is opened on the groove wall, the two movable pin shafts are in the same straight line, the mounting groove is connected to the front baffle and has a limit seat, the inner end of the movable pin shaft has a block, a first spring is connected between the two blocks, the block rests on the limit seat under the action of the first spring, the protective cover is fixed in the mounting groove, the inner side of the protective cover has a number of horizontally arranged guide columns, the pressing plate is sleeved on the guide columns and moves back and forth, the back of the pressing plate has a pressing portion that passes through the protective cover, an inclined strip sliding hole is opened on the movable pin shaft, and vertical axes for inserting into the strip sliding holes are provided on both sides of the pressing plate, and the outer end of the movable pin shaft can be inserted into the lock hole after passing through the front baffle.

[0013] Press the pressing portion of the pressing plate forward, causing it to move forward along the guide post. The vertical axis engages the bar-shaped sliding hole, driving the movable pin to retract into the front baffle. The movable pin's stop compresses the first spring, shortening it and allowing the storage basket to be withdrawn. When you release your grip, the first spring pushes the two movable pins outward, inserting their outer ends into the locking holes, locking the storage basket to the rack and simultaneously returning the pressing plate to its original position.

[0014] Furthermore, the drive assembly includes a storage motor, an outer cover shell, a sealing cover, a worm and a drive shaft. The storage motor is embedded in the outer cover shell. The worm and the drive shaft are both rotatably connected in the outer cover shell through bearings. The output shaft of the storage motor is connected to the worm and rotates synchronously. A worm wheel engaged with the worm is fixed on the drive shaft. The drive shaft is connected to the core shaft and rotates synchronously. The sealing cover is buckled on the outer cover shell.

[0015] The driving assembly is used to drive the core shaft and the roller brush plate to rotate. The storage motor drives the worm to rotate. The worm drives the drive shaft to rotate through the worm gear. The drive shaft is linked to the core shaft.

[0016] Furthermore, the locking assembly includes a clamping outer tube fixedly connected to the positioning sleeve, a clamping inner tube protruding from the inner wall of the end cover, and an unlocking block. The clamping inner tube can be inserted into the clamping outer tube, and the unlocking block is rotatably connected to the end cover. A U-shaped spring piece is embedded in the clamping inner tube, and the U-shaped spring piece has a raised column head. Through holes for the column head to pass through are provided on the peripheral walls of the clamping outer tube and the clamping inner tube. The unlocking block has a top column facing the column head. When the unlocking block swings, the top column can squeeze the column head to make it shrink into the clamping inner tube.

[0017] Furthermore, a square hole is provided on the end cover, and the unlocking block is located in the square hole. The unlocking block is L-shaped, and a second spring is provided at the bottom of the square hole. The outer end of the second spring rests on the unlocking block. The outer end of the positioning sleeve has a horizontally extended retaining edge, and a connecting hole is provided on the retaining edge. A plurality of threaded holes are provided on the mounting tube. After the connecting holes are aligned with the threaded holes, they are fastened by inserting bolts. A pull ring is connected to the positioning sleeve.

[0018] First, install the U-shaped spring clip into the clamping inner tube, allowing the column head to pass through the through-hole of the clamping inner tube. When installing the end cap, insert the clamping inner tube into the clamping outer tube. The ends of the column head and the top post are hemispherical, so the column head can be squeezed down by the clamping outer tube. When the through-hole of the clamping outer tube aligns with the through-hole of the clamping inner tube, the column head is lifted up by the U-shaped spring clip, locking the clamping inner tube and the clamping outer tube, completing the installation of the end cap and the positioning sleeve. When the end cap needs to be removed, press the unlocking block so that the top post squeezes the column head back into the clamping inner tube. At this time, the clamping inner tube can be directly pulled out to separate the end cap and the positioning sleeve.

[0019] Furthermore, the core shaft has a regular hexagonal cross-section, a hexagonal hole for inserting the core shaft is formed on the drive shaft, a center hole for passing the core shaft is formed on the roller brush plate, protective shields are embedded at both ends of the roller brush plate, and a slot is formed inside the protective shield to engage with the roller brush plate. The protective shield at one end near the drive assembly abuts against the slot wall, while the protective shield at the other end abuts against a positioning sleeve. A support washer is mounted on the core shaft and tightly abuts against the inner wall of the protective shield. The protective shield protects the core shaft and prevents the core shaft from contacting debris that could affect its normal rotation.

[0020] Press the unlocking block to allow the push column to push the column head back into the through hole of the clamping inner tube. At this time, pull the end cover outward to separate the end cover from the positioning sleeve. Then remove the bolts and pull out the positioning sleeve from the mounting tube. Since the core shaft and the positioning sleeve are rotatably connected through the bearing, the core shaft and the roller brush plate can be pulled out at the same time as the positioning sleeve is pulled out. The other end of the core shaft is simply inserted into the hexagonal hole of the drive shaft for easy removal.

[0021] Furthermore, the travel mechanism includes a drive motor and an impeller, the drive motor is fixed on the frame, and the impeller is fixed on the output shaft of the drive motor.

[0022] Compared with the existing technology, this water surface cleaning robot has the following advantages:

[0023] 1. A lock-off assembly is provided, so you don’t need to disassemble the drive assembly. You can directly pull out the positioning sleeve at the installation tube end, and pull out the core shaft and roller brush plate together, so the installation and removal of the roller brush mechanism are very quick and convenient.

[0024] 2. A switch assembly is provided to quickly unlock or lock the storage basket to prevent displacement of the basket.

[0025] 3. The protective cover can prevent the core shaft from being entangled with ropes, cloth, branches and other debris during rotation, which may cause rotation obstruction or even direct jamming.

[0026] 4. The roller brush adopts a split type, and the core shaft can be pulled out horizontally from the roller brush plate, which is easy to disassemble and clean. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The traveling mechanism 4 drives the entire water surface cleaning robot to move forward on the water surface, collects garbage floating on the water surface, and the roller brush mechanism 3 actively pushes leaves, branches and other debris into the through groove 11. Finally, the garbage is concentrated in the storage basket 21 of the storage mechanism 2. The storage basket 21 is pulled out from the through groove 11, and after cleaning the garbage inside, it is inserted back for continued use.

[0056] like Figure 4-6 As shown, the storage mechanism 2 includes a storage basket 21 that slides back and forth along the through slot 11, and a switch assembly 5 that can lock and unlock the position of the storage basket 21 and the rack 1. The storage basket 21 has two side panels 22 and a front baffle 23 with a hollow interior. The upper end of the storage basket 21 is rotatably connected to an upper cover 24, and the switch assembly 5 is arranged in the front baffle 23.

[0057] The frame 1 has a limit baffle 13 located in the through slot 11 and capable of preventing the storage basket 21 from sliding further backward. The slot wall of the through slot 11 is provided with a track slot 14 and a track slot 2 15. The outer sides of the two side panels 22 are provided with a slider 25 and a sliding shaft 26. The slider 25 can be embedded in the track slot 14 and slide along the track slot 14. The sliding shaft 26 can be embedded in the track slot 2 15 and slide along the track slot 2 15. The track slot 14 is provided with a positioning slot 16. The lower end of the slider 25 has a positioning point 27 that is inserted into the positioning slot 16. The track slot 2 15 is provided with a positioning slot 2 17. When the positioning point 27 is inserted into the positioning slot 16, the sliding shaft 26 just falls into the positioning slot 2 17.

[0058] The storage basket 21 slides along the wall of the through groove 11. When the storage basket 21 slides to a position against the limit baffle 13, the positioning point 27 is inserted into the positioning groove 16, and the sliding shaft 26 is inserted into the positioning groove 2 17, thereby achieving preliminary positioning of the storage basket 21.

[0059] like Figure 7 As shown, the switch assembly 5 includes a knob 51 rotatably connected to the front baffle 23 and two movable pins 52, a locking hole 18 for the movable pin 52 to be inserted is opened on the groove wall, and movable holes 28 for the outer ends of the movable pins 52 to pass through are opened on both sides of the front baffle 23, the inner ends of the movable pins 52 are eccentrically hinged to the knob 51 and the movable pins 52 can be inserted into the locking holes 18 by rotating the knob 51, an unlocking groove 53 and a locking groove 54 are opened on the side of the knob 51, and a convex strip 29 is provided in the front baffle 23 to be inserted into the unlocking groove 53 or the locking groove 54.

[0060] By turning the knob 51, the movable pin 52 can be extended out of the front baffle 23 or retracted into the front baffle 23. When the outer end of the movable pin 52 is inserted into the lock hole 18, the storage housing 21 and the frame 1 are completely locked and no longer slide relative to each other. The ridge 29 is used to position the knob 51 to prevent it from rotating at will.

[0061] like Figure 12-14 As shown, the roller brush mechanism 3 includes a drive assembly 6, a roller brush plate 31, a core shaft 32, a positioning sleeve 33 and an end cover 34. The drive assembly 6 is fixed on one side of the frame 1, and the other side of the frame 1 has a mounting cylinder 12. The positioning sleeve 33 is embedded in the mounting cylinder 12 and fixed to the mounting cylinder 12. Several roller brush plates 31 are sleeved on the core shaft 32 and rotate synchronously with the core shaft 32. One end of the core shaft 32 is dynamically connected to the drive assembly 6, and the other end of the core shaft 32 is rotatably connected to the inner end of the positioning sleeve 33 through a bearing. A locking assembly 7 is provided between the outer end of the positioning sleeve 33 and the end cover 34, which can quickly connect and separate the two.

[0062] like Figure 14-16 As shown, the locking assembly 7 includes a clamping outer tube 71 fixedly connected to the positioning sleeve 33, a clamping inner tube 72 protruding from the inner wall of the end cover 34, and an unlocking block 73. The clamping inner tube 72 can be inserted into the clamping outer tube 71, and the unlocking block 73 is rotatably connected to the end cover 34. A U-shaped spring piece 74 is embedded in the clamping inner tube 72, and the U-shaped spring piece 74 has a raised column head 75. The peripheral walls of the clamping outer tube 71 and the clamping inner tube 72 are both provided with through holes 76 for the column head 75 to pass through. The unlocking block 73 has a top column 77 facing the column head 75. When the unlocking block 73 swings, the top column 77 can squeeze the column head 75 to make it shrink into the clamping inner tube 72.

[0063] A square hole is provided on the end cover 34, and an unlocking block 73 is located in the square hole. The unlocking block 73 is L-shaped, and a second spring 78 is provided at the bottom of the square hole. The outer end of the second spring 78 rests on the unlocking block 73. The outer end of the positioning sleeve 33 has a horizontally extended retaining edge 35, and a connecting hole 36 is provided on the retaining edge 35. A plurality of threaded holes 19 are provided on the mounting tube 12. After the connecting holes 36 are aligned with the threaded holes 19, they are fastened by inserting bolts. A pull ring 37 is connected to the positioning sleeve 33.

[0064] First, install the U-shaped spring piece 74 into the clamping inner tube 72 so that the stud 75 passes through the through hole 76 of the clamping inner tube 72. When installing the end cap 34, insert the clamping inner tube 72 into the clamping outer tube 71. The stud 75 and the top post 77 have hemispherical ends, so the stud 75 can be squeezed and sunk by the clamping outer tube 71. When the through hole 76 of the clamping outer tube 71 is aligned with the through hole 76 of the clamping inner tube 72, the stud 75 is lifted by the U-shaped spring piece 74, locking the clamping inner tube 72 and the clamping outer tube 71, completing the installation of the end cap 34 and the positioning sleeve 33. When it is necessary to remove the end cap 34, press the unlocking block 73 so that the top post 77 squeezes the stud 75 back into the clamping inner tube 72. At this time, the clamping inner tube 72 can be directly pulled out, completing the separation of the end cap 34 and the positioning sleeve 33. After removing the bolts, hold the pull ring 37 and pull it outwards to facilitate pulling the positioning sleeve 33 out of the installation tube 12.

[0065] The core shaft 32 has a regular hexagonal cross-section. The drive shaft 65 is provided with a hexagonal hole 67 for inserting the core shaft 32. The roller brush plate 31 is provided with a central hole for the core shaft 32 to pass through. Protective covers 38 are embedded at both ends of the roller brush plate 31. The inner side of the protective cover 38 has a slot that engages with the roller brush plate 31. The protective cover 38 at one end near the drive assembly 6 abuts against the slot wall, while the protective cover 38 at the other end abuts against the positioning sleeve 33. A support washer 39 is sleeved on the core shaft 32 and is in close contact with the inner wall of the protective cover 38. The protective cover 38 is used to protect the core shaft 32 and prevent it from contacting debris that could affect its normal rotation.

[0066] When the locking cam 33 is unlocked, the locking cam 33 is unlocked and the locking cam 33 is unlocked. When the locking cam 33 is unlocked, the locking cam 33 is unlocked and the master lock cam 33 is unlocked.

[0067] like Figure 17-18 As shown, the drive assembly 6 includes a storage motor 61, an outer housing 62, a sealing cover 63, a worm 64, and a drive shaft 65. The storage motor 61 is embedded in the outer housing 62. The worm 64 and the drive shaft 65 are both rotatably connected in the outer housing 62 via bearings. The output shaft of the storage motor 61 is connected to the worm 64 and rotates synchronously. A worm gear 66 is fixed to the drive shaft 65 and engages with the worm 64. The core shaft 32 is plugged into the hexagonal hole 67 of the drive shaft 65 and rotates synchronously. The sealing cover 63 is buckled onto the outer housing 62. The drive assembly 6 is used to drive the core shaft 32 and the roller brush plate 31 to rotate. The storage motor 61 drives the worm 64 to rotate. The worm 64 drives the drive shaft 65 to rotate through the worm gear 66. The drive shaft 65 is linked to the core shaft 32.

[0068] like Figure 14 As shown, since the roller brush plate 31 occasionally gets entangled with debris, it needs to be removed and cleaned in time before being reinstalled. The inner end of the positioning sleeve 33 is fixed to the bearing by the limit screw 79. When disassembling, the positioning sleeve 33 is pulled out, and the core shaft 32 and the roller brush plate 31 are pulled out from the installation tube 12 together.

[0069] Example 2

[0070] like Figure 8-11As shown, the difference from the first embodiment lies in the structure of the switch assembly 5. The switch assembly 5 of this embodiment includes a pressing plate 55, a protective cover 56 and two movable pins 52. The slot wall is provided with a lock hole 18 for the movable pins 52 to be inserted. The two movable pins 52 are in the same straight line. The mounting slot is connected to the front baffle 23 and has a limit seat 57. The inner end of the movable pin 52 has a stopper 58. A first spring 59 is connected between the two stoppers 58. The stopper 58 is pressed against the limit seat 57 under the action of the first spring 59 to ensure the stopper. The protective cover 56 is fixed in the mounting groove. The inner side of the protective cover 56 has a number of horizontally arranged guide columns 510. The pressing plate 55 is sleeved on the guide columns 510 and moves back and forth. The back of the pressing plate 55 has a pressing portion 511 that passes through the protective cover 56. The movable pin shaft 52 has an inclined strip-shaped sliding hole 512. The pressing plate 55 has vertical shafts 513 on both sides for inserting into the strip-shaped sliding hole 512. The outer end of the movable pin shaft 52 passes through the front baffle 23 and can be inserted into the lock hole 18.

[0071] Manually press the pressing portion 511 of the pressing plate 55 forward, causing the pressing plate 55 to move forward along the guide post 510. As the vertical axis 513 cooperates with the strip-shaped sliding hole 512, the movable pin 52 is retracted into the front baffle 23. The stopper 58 of the movable pin 52 compresses the first spring 59, causing it to shorten, allowing the storage basket 21 to be withdrawn. When the user releases the pressure, the first spring 59 pushes the two movable pins 52 outward, causing their outer ends to insert into the locking holes 18, locking the storage basket 21 to the frame 1. Simultaneously, the pressing plate 55 returns to its original position.

[0072] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
