Description

Technical Field

[0001] This utility model relates to the field of sweeping robot technology, and in particular to a mop device and a sweeping machine. Background Technology

[0002] Robotic vacuum cleaners have entered thousands of households, becoming intelligent helpers for cleaning in people's lives.

[0003] The front and middle sections of a robotic vacuum cleaner are equipped with side brush modules, roller brush modules, and vacuuming modules for sweeping; the rear and middle sections are equipped with mop modules for mopping.

[0004] The mop module can be configured as a mop cover and a roller mop. The mop cover is hinged to the housing of the sweeper, allowing it to swing up and down to raise and lower the roller mop. The radius of the roller mop is larger than that of the mop cover, with a portion protruding from the bottom of the mop cover to contact the ground for mopping.

[0005] When the roller mop descends, its bottom rests on the ground to clean the floor. When the roller mop rises, its bottom leaves the ground, allowing the robot vacuum to move and perform functions such as sweeping and vacuuming independently.

[0006] Because approximately 1 / 4 to 1 / 3 of the roller mop head protrudes from the bottom of the mop cover, it is impossible to install a covering structure at the bottom opening of the mop cover to conceal the bottom of the roller mop head. Therefore, in the prior art, the bottom portion of the roller mop head is completely exposed. Even when the roller mop head is not in use and is raised, its bottom is still exposed under the mop cover, making it visible to the user. When sweeping a carpet, even if the roller mop head is raised, dirty water or dirt from the roller mop head may drip or fall and contaminate the carpet. Utility Model Content

[0007] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a mop device and a sweeper, wherein the mop cover is equipped with a shield. When the mop assembly is in the raised state, the shield moves to the lower part of the mop cover to shield the roller mop, thereby overcoming the defects in the prior art.

[0008] This utility model provides a mop device, including an installation structure, a mop assembly pivotally connected to the installation structure and capable of swinging up and down, and a drive module for driving the mop assembly to swing up and down. The mop assembly includes a mop cover hinged to the mounting structure and drivenly connected to the drive module, and a roller mop pivotally connected to the mop cover, a portion of which protrudes from a bottom opening in the mop cover; The outer peripheral surface of the mop cover is equipped with a shield, which is slidably connected to the mop cover and can be driven by a drive structure to switch positions between the upper and lower parts of the mop cover. When the mop assembly is in the lowered state, the shield is located above the mop cover to expose the roller mop; When the mop assembly is in the raised state, the shield is located below the mop cover and covers the roller mop.

[0009] In one of the alternative technical solutions, the drive structure includes a linkage transmission assembly connected between the shield and the mop cover; When the mop assembly is driven to swing up and down, the shield can be slid back and forth along the circumference of the mop cover by the linkage transmission assembly.

[0010] In one of the optional technical solutions, the linkage transmission component has an engaged state and a disengaged state; When the mop assembly descends to its limit position, the linkage transmission assembly is in a disengaged state; After the mop assembly is moved from its extreme position to a preset angle, the linkage transmission assembly is in an engaged state.

[0011] In one of the alternative technical solutions, the linkage transmission assembly includes a fixed rack, a transmission gear meshing with the fixed rack, and a swinging member fixedly connected to the transmission gear; The transmission gear is pivotally connected to the side end cover of the mop cover, and the fixed rack is arranged vertically on the front side of the transmission gear. The swinging component is swingably arranged on the outside of the side end cover and is fixedly connected to the shielding cover.

[0012] In one alternative technical solution, when the mop assembly descends to its limit position, the transmission gear separates from the fixed rack, and the transmission gear is located obliquely below the fixed rack; After the mop assembly is moved from its extreme position to a preset angle, the transmission gear engages with the fixed rack.

[0013] In one of the alternative technical solutions, the fixed rack has a preset curvature.

[0014] In one of the alternative technical solutions, the end of the shield has a limiting groove, and the side edge of the mop cover has a guide flange, which is inserted into the limiting groove.

[0015] In one of the alternative technical solutions, the cross-sections of the shield and the mop cover are respectively arc-shaped, and the central angle of the shield is larger than the central angle of the bottom opening of the mop cover; When the shield is positioned below the mop cover, the shield completely covers the bottom opening.

[0016] In one of the alternative technical solutions, the linkage transmission assembly is connected between the first end of the shield and the first end of the mop cover; The second end of the mop cover is provided with a side end cover. The side end cover is provided with an installation port for installing the roller mop and a baffle for inserting into the installation port to stop the roller mop. The baffle is detachably connected to the side end cover.

[0017] The present invention also provides a sweeping machine, including the mop device described in any of the foregoing technical solutions.

[0018] The above technical solution has the following beneficial effects: This utility model provides a mop device and a sweeper, including a mounting structure, a mop assembly, and a drive module. The mounting structure is used to fix the mop assembly to the housing of the sweeper. The mop assembly is pivotally connected to the mounting structure, allowing it to swing up and down to lift off the ground and lower onto the ground. The drive module is used to drive the mop assembly to swing up and down, automatically driving the mop assembly to lift off the ground and lower onto the ground.

[0019] The mop assembly includes a mop cover and a roller mop. The mop cover is hinged to a mounting structure and can swing up and down relative to the mounting structure. The roller mop is mounted inside the mop cover via a pivot, with its bottom portion protruding from the bottom opening of the mop cover.

[0020] A shield is installed on the outer circumferential surface of the mop cover. The shield is slidably connected to the mop cover and can be driven by a drive structure to slide back and forth along the circumference of the mop cover, thereby changing position between the upper and lower parts of the mop cover.

[0021] When the mop assembly is in the lowered position, the shield moves to the top of the mop cover to expose the roller mop without affecting the normal use of the roller mop.

[0022] When the mop assembly is in the raised position, the shield moves to the lower part of the mop cover to cover the bottom part of the roller mop that is exposed under the mop cover.

[0023] With this design, when the roller mop is not in use, the bottom part of the roller mop is covered by a shield, so the user cannot see the roller mop. This improves the user's viewing experience and also prevents dirty water and dirt from dripping or falling from the roller mop and soiling the carpet. This overcomes the shortcomings of existing technologies and improves the performance of the product. Attached Figure Description

[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0026] like Figure 1-2 , Figure 5-7 and Figure 9-11 As shown, a mop device provided in one embodiment of the present invention includes an installation structure 1, a mop assembly 2 that is pivotally connected to the installation structure 1 and capable of swinging up and down, and a drive module 3 for driving the mop assembly 2 to swing up and down.

[0027] The mop assembly 2 includes a mop cover 21 hinged to the mounting structure 1 and driven by the drive module 3, and a roller mop 22 pivotally connected to the mop cover 21, a portion of which protrudes from the bottom opening 211 of the mop cover 21.

[0028] The outer peripheral surface of the mop cover 21 is equipped with a shield 23, which is slidably connected to the mop cover 21 and can be driven by the drive structure 4 to switch positions between the upper and lower parts of the mop cover 21.

[0029] When the mop assembly 2 is in the lowered state, the shield 23 is above the mop cover 21 to expose the roller mop 22.

[0030] When the mop assembly 2 is in the raised state, the shield 23 is located below the mop cover 21 and covers the roller mop 22.

[0031] The present invention provides a mop device, including an installation structure 1, a mop assembly 2, and a drive module 3, etc.

[0032] Mounting structure 1 is used to fix the sweeper to its housing. Mounting structure 1 can be a mounting bracket, mounting plate, etc.

[0033] The mop assembly 2 is pivotally connected to the mounting structure 1, allowing it to swing up and down to lift off the ground and lower to the ground.

[0034] The pivotable connection in this invention refers to the connection of two components via a hinge or pivot, allowing them to swing or rotate relative to each other.

[0035] The drive module 3 is used to drive the mop assembly 2 to swing up and down, automatically lifting the mop assembly 2 off the ground and lowering it back to the ground. The drive assembly 3 can be an electrode screw, piston, etc., mounted on the fixed structure 1 and hinged to the mop assembly 2. The extension and retraction of the electrode screw or piston drives the mop assembly 2 to swing up and down. Alternatively, the drive assembly 3 can be a motor-driven rope mechanism, using a rope to lift the mop assembly 2. Any drive component or combination capable of driving the mop assembly 2 to swing up and down can be used in this invention.

[0036] The mop assembly 2 includes a mop cover 21 and a roller mop 22. The mop cover 21 is longitudinally shaped with an arched cross-section for mounting the roller mop 22. The bottom of the mop cover 21 has a bottom opening 211, the sides of the mop cover 21 have side end caps 212, and the rear of the mop cover 21 has a swing arm 213. The swing arm 213 is hinged to the mounting structure 1, thereby allowing the mop cover 21 to swing up and down relative to the mounting structure 1.

[0037] The roller mop 22 is mounted inside the mop cover 21 via a rotating shaft, or the roller mop 22 is mounted on a drive shaft inside the mop cover 21, so that it can be driven to rotate. The radius of the roller mop 22 is larger than the radius of the mop cover 21, and the bottom part of the roller mop 22 protrudes from the bottom opening 211 of the mop cover 21.

[0038] In this invention, a shielding cover 23 is installed on the outer peripheral surface or the upper surface of the mop cover 21.

[0039] The shield 23 is slidably connected to the mop cover 21 and can be driven by the drive structure 4 to reciprocate along the circumference of the mop cover 21, thereby changing its position between the upper and lower parts of the mop cover 21. The drive structure 4 can be an active drive component, such as a motor or piston, which drives the mop cover 21 to swing and achieve position switching. The drive structure 4 can also be a linkage drive component, such as the linkage transmission assembly 41 described later, which is linked to the mop cover 21 and swings with the up and down swing of the mop cover 21 to achieve position switching.

[0040] Specifically, when the mop assembly 2 changes from the raised state to the lowered state, the shield 23 is driven by the drive structure 4 to move from the lower part of the mop cover 21 to the upper part of the mop cover 21 to expose the roller mop 22 without affecting the normal use of the roller mop 22.

[0041] When the mop assembly 2 changes from the lowered state to the raised state, the shield 23 is driven by the drive structure 4 to move from the upper part of the mop cover 21 to the lower part of the mop cover 21 to cover or enclose the bottom part of the roller mop 22 exposed by the mop cover 21.

[0042] With this design, when the roller mop 22 is not in use, the bottom part of the roller mop 22 is covered by the shield 23, so the user cannot see the roller mop 22, which improves the user's viewing experience. When the sweeper performs the sweeping function alone, it can also prevent the roller mop 22 from dripping or falling and soiling the carpet, overcoming the defects of the prior art and improving the performance of the product.

[0043] In one embodiment, such as Figure 1-2 , Figure 5 and Figure 9-11 As shown, the drive module 3 includes a motor 31 and a wedge block 32. The motor 31 is fixed to the mounting structure 1, and the wedge block 32 is slidably connected to the mounting structure 1. The motor 31 is connected to the wedge block 32 via a cable, which drives the wedge block 32 to move toward the side of the motor 31. A tension spring connects the wedge block 32 to the mounting structure 1, which pulls the wedge block 32 toward the side away from the motor 31.

[0044] A hook 214 is provided on the rear side of the mop cover 21. When the wedge block 32 moves toward the motor 31 and inserts into the hook 214, its inclined surface can be used to make the mop cover 21 swing backward and upward, thereby driving the roller mop 22 to rise off the ground. When the wedge block 32 moves in the opposite direction under the action of the tension spring, the wedge block 32 leaves the hook 214. Under the action of gravity and / or torsion spring, the mop assembly 2 swings downward and forward, so that the roller mop 22 falls to the ground.

[0045] In one embodiment, such as Figure 1-2 As shown, the drive structure 4 includes a linkage transmission assembly 41, which is connected between the shield 23 and the mop cover 21. When the mop assembly 2 is driven to swing up and down, the shield 23 can be slid back and forth along the circumference of the mop cover 21 by the linkage transmission assembly 41.

[0046] In this embodiment, the drive structure 4 adopts the linkage transmission component 41, eliminating the need for an active drive component. The linkage transmission component 41 is driven to move by the up-and-down swing of the mop cover 21, which in turn drives the shield 23 to slide back and forth along the circumference of the mop cover 21, thereby realizing the switching position between the upper and lower parts of the mop cover 21.

[0047] This configuration saves on active drive components, reduces installation space, facilitates installation, and reduces costs.

[0048] Specifically, when the mop cover 21 swings from top to bottom, the shield 23 slides from the lower part of the mop cover 21 to the upper part of the mop cover 21; when the mop cover 21 swings from bottom to top, the shield 23 slides from the upper part of the mop cover 21 to the lower part of the mop cover 21.

[0049] In one embodiment, such as Figure 1-2 As shown, the linkage transmission assembly 41 has an engaged state and a disengaged state.

[0050] When the mop assembly 2 descends to its limit position, the linkage transmission assembly 41 is in a disengaged state.

[0051] After the mop assembly 2 is moved from its extreme position to a preset angle, the linkage transmission assembly 41 is engaged.

[0052] In this embodiment, the linkage transmission component 41 adopts a clutch structure, which has an engaged state and a disengaged state.

[0053] When the mop assembly 2 is in the ground position, that is, when it has descended to its limit position, the linkage transmission assembly 41 is in the disengaged state. The linkage transmission assembly 41 does not drive the shield 23, but keeps the shield 23 above the mop cover 21 to expose the bottom of the roller mop 22. At this time, since the linkage transmission assembly 41 is in the disengaged state, the shaking or swaying of the roller mop 22 during mopping will not be transmitted to the shield 23 through the linkage transmission assembly 41, thus preventing the shield 23 from moving with the shaking or swaying of the roller mop 22 during mopping.

[0054] When the mop assembly 2 is in the raised or lifted state, the linkage transmission assembly 41 is engaged, which drives the shield 23 to slide from the upper part of the mop cover 21 to the lower part of the mop cover 21 to cover the bottom of the roller mop 22.

[0055] That is, when the mop assembly 2 is switched from being placed on the ground to being lifted, the linkage transmission assembly 41 causes the shield 23 to slide from the upper part of the mop cover 21 to the lower part of the mop cover 21; when the mop assembly 2 is switched from being lifted to being placed on the ground, the linkage transmission assembly 41 causes the shield 23 to slide from the lower part of the mop cover 21 to the upper part of the mop cover 21.

[0056] When the mop assembly 2 reaches its limit position, the linkage transmission assembly 41 is in a disengaged state and no longer drives the shield 23. Instead, the shield 23 remains above the mop cover 21 to expose the bottom of the roller mop 22. The shaking or swaying of the roller mop 22 during mopping will not be transmitted to the shield 23 through the linkage transmission assembly 41, thus preventing the shield 23 from moving with the shaking or swaying of the roller mop 22 during mopping.

[0057] In one embodiment, such as Figure 1-4 and Figure 9-10 As shown, the linkage transmission assembly 41 includes a fixed rack 411, a transmission gear 412 that meshes with the fixed rack 411, and a swing member 413 that is fixedly connected to the transmission gear 412.

[0058] The transmission gear 412 is pivotally connected to the side end cover 212 of the mop cover 21, and the fixed rack 411 is arranged vertically on the front side of the transmission gear 412.

[0059] The swinging component 413 is swingably arranged on the outside of the side end cover 212 and is fixedly connected to the shield 23.

[0060] In this embodiment, the linkage transmission assembly 41 includes a fixed rack 411, a transmission gear 412, and a swing member 413.

[0061] The fixed rack 411 is fixedly connected to the housing of the sweeper and is arranged vertically in front of the transmission gear 412. The fixed rack 411 has multiple teeth arranged vertically and horizontally on the side facing the transmission gear 412.

[0062] The transmission gear 412 is mounted on the outside of the side end cover 212 via a rotating shaft, and the transmission gear 412 can rotate relative to the side end cover 212 and the mop cover 21. The transmission gear 412 meshes with the fixed rack 411 for transmission.

[0063] The swing member 413 is arranged on the outside of the side end cover 212 and can swing relative to the side end cover 212. One end of the swing member 413 is fixedly connected to the transmission gear 412, and the other end is fixedly connected to the end of the shield 23.

[0064] Preferably, the swing member 413 has a fan-shaped structure, the transmission gear 412 is connected to the narrower end of the swing member 413, and the longer end of the swing member 413 is fixedly connected to the end of the shield 23.

[0065] This setting, combined with Figure 9 As shown, at this time, the mop assembly 2 is in the raised state, the mop cover 21 is in the high position, and the shield 23 is located below the mop cover 21. When the mop assembly 2 descends to... Figure 1 During the process shown, the mop cover 21 swings from top to bottom, and the transmission gear 412 is rotated counterclockwise by the fixed rack 411, thereby driving the shield 23 to swing upward through the swinging member 413, and then slide to the upper part of the mop cover 21.

[0066] Combination Figure 1 As shown, at this time, the mop assembly 2 is in a lowered state, the mop cover 21 is in a low position, and the shield 23 is above the mop cover 21. When the mop assembly 2 rises to... Figure 9 During the process shown, the mop cover 21 swings from bottom to top, and the transmission gear 412 is rotated clockwise by the fixed rack 411, thereby driving the shield 23 to swing downward through the swinging member 413, and then slide to the lower part of the mop cover 21.

[0067] In one embodiment, such as Figure 1-2As shown, when the mop assembly 2 descends to its limit position, the transmission gear 412 separates from the fixed rack 411, and the transmission gear 412 is located diagonally below the fixed rack 411.

[0068] After the mop assembly 2 is moved from its extreme position to a preset angle, the transmission gear 412 meshes with the fixed rack 411.

[0069] In this embodiment, when the transmission gear 412 is separated from the fixed rack 411, the linkage transmission component 41 is in a separated state; when the transmission gear 412 is engaged with the fixed rack 411, the linkage transmission component 41 is in a engaged state.

[0070] With this configuration, when the mop assembly 2 performs the mopping task, the transmission gear 412 is separated from the fixed rack 411, and the swing amplitude of the mop assembly 2 during mopping is relatively small, so that the transmission gear 412 and the fixed rack 411 will not mesh, thus preventing the shield 23 from swinging / shaking with the mop assembly 2 during mopping.

[0071] In one embodiment, such as Figure 3 As shown, the fixed rack 411 has a preset curvature to accommodate the swing trajectory of the transmission gear 412 as the mop cover 21 moves. Preferably, the center of the fixed rack 411 is located at the pivot center with respect to the mop cover 21.

[0072] In one embodiment, such as Figure 4 As shown, the transmission gear 412 and the swing component 413 are integrated, which facilitates processing and forming, has high structural strength, and a long service life.

[0073] In one embodiment, such as Figure 8 As shown, the end of the shield 23 has a limiting groove 231, and the side edge of the mop cover 21 has a guide flange 215. The guide flange 215 is inserted into the limiting groove 231, which improves the assembly stability of the shield 23 and the mop cover 21, and also helps to guide the shield 23 to slide along the mop cover 21.

[0074] In one embodiment, such as Figure 6-7 and Figure 9-11 As shown, the cross-sections of the shield 23 and the mop cover 21 are both arc-shaped, and the central angle of the shield 23 is larger than the central angle of the bottom opening 211 of the mop cover 21. When the shield 23 is located at the lower part of the mop cover 21, the shield 23 completely covers the bottom opening 211.

[0075] In this embodiment, the arc length of the shield 23 is greater than the arc length occupied by the bottom opening 211 of the mop cover 21. Therefore, when the shield 23 is located at the lower part of the mop cover 21, the shield 23 completely covers the bottom opening 211 and can completely cover the bottom part of the roller mop 22.

[0076] In one embodiment, such as Figure 1-2 , Figure 6-7 and Figure 9-11 As shown, the linkage transmission assembly 41 is connected between the first end 23a of the shield 23 and the first end 21a of the mop cover 21.

[0077] The second end 21b of the mop cover 21 is provided with a side end cover 21c. The side end cover 21c is provided with an installation port 21d for installing the roller mop 22 and a baffle 21e for inserting into the installation port 21d to stop the roller mop 22. The baffle 21e is detachably connected to the side end cover 21c.

[0078] In this embodiment, the mop cover 21 is divided into a first end 21a and a second end 21b along the axial direction of the roller mop 22, and the shield 23 is divided into a first end 23a and a second end 23b along the axial direction of the roller mop 22. The first end 23a of the shield 23 is slidably mounted on the first end 21a of the mop cover 21, and the second end 23b of the shield 23 is slidably mounted on the second end 21b of the mop cover 21. The aforementioned limiting groove 231 is provided at the second end 23b of the shield 23, and the aforementioned guide flange 215 is provided at the second end 21b of the mop cover 21.

[0079] The linkage transmission assembly 41 is mounted between the first end 23a of the shield 23 and the first end 21a of the mop cover 21, making it more convenient to remove the roller mop 22 from the second end 21b of the mop cover 21.

[0080] Therefore, a side end cap 21c is provided at the second end 21b of the mop cover 21, which has an installation opening 21d for installing the roller mop 22. A baffle 21e is connected to the side end cap 21c, which is inserted into the installation opening 21d to stop the roller mop 22. The baffle 21e and the side end cap 21c are detachably connected by pins, buckles, etc.

[0081] When it is necessary to disassemble or assemble the roller mop 22, remove the baffle 21e from the side end cover 21c to expose the mounting port 21d. The user can then disassemble or assemble the roller mop 22 through the mounting port 21d. After disassembly or assembly, reassemble the baffle 21e onto the side end cover 21c. One end of the baffle 21e extends into the mounting port 21d to act as a block or stop.

[0082] like Figure 12-13As shown, one embodiment of the present invention provides a sweeping machine, which includes the mop device described in any of the foregoing embodiments.

[0083] The sweeper includes a housing 7 and a mop assembly. The housing 7 is the rear housing of the sweeper, and the mop assembly is the aforementioned mop assembly.

[0084] The bottom of the housing 7 has a groove 71 for mounting the mop assembly 2. The mounting structure 1 is mounted on the bottom of the housing 7 and is located on one side of the groove 71.

[0085] like Figure 12 As shown, the mop assembly 2 is in a lowered state at this time, and the roller mop 22 is used to sweep the floor. The shield 23 is located on the upper part of the mop cover 21.

[0086] like Figure 13 As shown, the mop assembly 2 is in the raised state at this time, and the roller mop 22 is no longer in use. The cover 23 is located at the lower part of the mop cover 21 and covers the part of the roller mop 22 that extends out of the bottom opening 211. The user cannot see the roller mop 22, which improves the user's viewing experience. When the sweeper performs the sweeping function alone, the debris will not come into contact with the roller mop 22, nor will it enter the mop cover 21, overcoming the defects in the prior art and improving the performance of the product.

[0087] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0088] The above are merely the principles and preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several other modifications can be made based on the principles of this utility model, and these modifications should also be considered within the scope of protection of this utility model.
