Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a cleaning device and a cleaning equipment. Background Art

[0002] A sweeping robot is a device that can automatically clean while moving. It cleans the floor, walls or other areas that need cleaning through cleaning components such as roller brushes, side brushes, rags or hanging boards in the cleaning device, which can reduce manual labor intensity and improve cleaning efficiency.

[0003] In the related art, when the cleaning component contacts the ground for cleaning, it may encounter water stains, dirt or obstacles. In order to avoid damage to the cleaning component or dirt in other areas, a screw and a threaded sleeve are usually provided. The screw and the threaded sleeve rotate relative to each other to control the screw or the sleeve to rise or fall, so as to drive the cleaning component to rise or fall, and achieve contact or separation between the cleaning component and the ground. Since this method requires reserved movement space for the screw or the threaded sleeve, the cleaning device occupies a large space, which is not conducive to enhancing the compactness of the cleaning equipment and causes poor passability of the cleaning equipment.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0059] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0060] See also Figures 1 to 7, this embodiment provides a cleaning device 10, which includes a cleaning assembly 100, a rotating member 200 and a lifting transmission member 300. The rotating member 200 is configured to be rotatable around a first axis R, and the rotating member 200 is provided with a first transmission part 210; the lifting transmission member 300 is provided with a second transmission part 310 and a third transmission part 320, the second transmission part 310 is in contact with the first transmission part 210, and can be rotatably arranged around its own central axis relative to the first transmission part 210; the third transmission part 320 is respectively connected to the second transmission part 310 and the cleaning assembly 100. Among them, the third transmission part 320 is configured to form a preset angle K with the flip axis S, and is radially limited with the cleaning assembly 100; the first transmission part 210 is used to drive the second transmission part 310 to rotate around the first axis R, so that the third transmission part 320 follows the second transmission part 310 to rotate around the first axis R, and drives the cleaning assembly 100 to rotate around the flip axis S under the action of the preset angle K.

[0061] Among them, the first axis R can be an axis passing through the center of the rotating member 200, and the rotating member 200 can be rotatably arranged around the first axis R. Its driving force source can be a driving motor, but it can also be other devices that output driving force, such as a thermal engine, a hydraulic mechanism, etc.

[0062] When the rotating member 200 rotates around the first axis R, the first transmission part 210 on the rotating member 200 rotates synchronously, thereby applying abutting force to the second transmission part 310 , thereby driving the second transmission part 310 to rotate around the first axis R.

[0063] Among them, the third transmission part 320 is fixedly connected to the second transmission part 310, which can be integrally formed, or can be bonded, welded, clamped, threaded, or other methods, which are not specifically limited in this embodiment. The third transmission part 320 is connected to the cleaning component 100, and can rotate around the first axis R relative to the cleaning component 100, and is radially limited relative to the cleaning component 100, that is, abutted in the radial direction. Since the third transmission part 320 and the flip axis S form a preset angle K, when the third transmission part 320 follows the second transmission part 310 to rotate around the first axis R, a radial component force will be formed due to the effect of the preset angle K, so that the third transmission part 320 abuts against the cleaning component 100 in the radial direction, pushing the cleaning component 100 to rotate around the flip axis S. Since the second transmission part 310 can rotate around its own central axis relative to the first transmission part 210, the radial movement of the third transmission part 320 will not be restricted by the second transmission part 310. When the third transmission part 320 drives the cleaning assembly 100 to rotate around the flip axis S, the second transmission part 310 rotates around its own central axis synchronously. The flip axis S can be the flip central axis of the cleaning assembly 100. When the cleaning assembly 100 rotates around the flip axis S, it flips relative to the surface to be cleaned, and is lifted or lowered relative to the surface to be cleaned, and then separated from or contacted with the surface to be cleaned.

[0064] For easier understanding, see Figure 7 and Fig.10 When the second transmission part 310 rotates around the first axis R in the direction R1, the third transmission part 320 rotates accordingly. However, since the third transmission part 320 forms a preset angle K with the flip axis S, and the third transmission part 320 and the cleaning component 100 are radially limited, the torque of the third transmission part 320 along the first axis R is partially converted into a torque around its own central axis and an abutment force along the first radial direction G of the axis. The abutment force on the first radial direction G acts on the cleaning component 100, which is equivalent to the cleaning component 100 being subjected to a tangential force around the flip axis S, forming a torque around the flip axis S, thereby rotating around the flip axis S, so that the cleaning component 100 is flipped, and the cleaning component 100 is lifted and lowered.

[0065] Therefore, in this embodiment, there is no need to set a component that performs lifting and lowering motion in the cleaning device 10 to drive the cleaning component 100 to rise and fall. Instead, through the cooperation of the rotating member 200 and the lifting transmission member 300, the rotation of the rotating member 200 around the first axis R is converted into the rotation of the cleaning component 100 around the flipping axis S, so that the cleaning component 100 can be flipped relative to the surface to be cleaned to achieve lifting and lowering, thereby reducing the space occupied by the cleaning device 10, which is beneficial to enhancing the structural compactness and passability of the cleaning equipment.

[0066] In addition, since the screw rod and the threaded sleeve will slide relative to each other in the axial direction when they are matched, it is easy to generate large noise and friction, which further affects the service life of the cleaning device 10. In this embodiment, through the matching of the rotating member 200 and the lifting transmission member 300, the rotation of the rotating member 200 around the first axis R is converted into the rotation of the cleaning assembly 100 around the flip axis S, which reduces noise and friction and can increase the service life of the cleaning device 10.

[0067] The cleaning assembly 100 of this embodiment may be a side brush assembly, which mainly rotates and cleans by friction with the ground, pushing garbage to the suction port of the cleaning robot to improve the cleaning effect, but may also be a roller brush assembly, a rag plate assembly or a scraper assembly, etc. The surface to be cleaned in this embodiment may be the ground, but may also be a wall, a glass surface, etc.

[0068] See also Figure 5 In one embodiment, the cleaning assembly 100 includes a cleaning portion 110 and a flip portion 120, the cleaning portion 110 extends from the flip portion 120 in a direction away from the first axis R, and has a descending position F1 and an ascending position F2 that are flipped around the flip axis S; the flip portion 120 is connected to the third transmission portion 320; when the third transmission portion 320 follows the second transmission portion 310 to rotate around the first axis R, it drives the flip portion 120 to rotate around the flip axis S, so that the cleaning portion 110 moves between the descending position F1 and the ascending position F2; wherein the first axis R and the flip axis S are vertically arranged.

[0069] The cleaning portion 110 extends from the flip portion 120 in a direction away from the first axis R, and is disposed close to the surface to be cleaned, for cleaning the surface to be cleaned. The cleaning portion 110 may include a side brush, and the side brush may be provided with bristles for cleaning the surface to be cleaned. The flip portion 120 is fixedly connected to the cleaning portion 110, and may be integrally formed, or may be bonded, welded, clamped, or other methods, which are not specifically limited in this embodiment.

[0070] The cleaning part 110 is configured to be flippable around a flip axis S, and has a descending position F1 and an ascending position F2 relative to the surface to be cleaned. When the cleaning part 110 is in the ascending position F2, it is separated from the surface to be cleaned, and when the cleaning part 110 is in the descending position F1, it is in contact with the surface to be cleaned.

[0071] Among them, the first axis R and the flip axis S are set to be vertical, so that the transmission efficiency of converting the rotation of the rotating member 200 around the first axis R into the flipping of the cleaning component 100 around the flip axis S is higher. In addition, for example, the first axis R can be set vertically, perpendicular to the ground when cleaning the surface to be cleaned, and the flip axis S can be set horizontally, parallel to the ground when cleaning the surface to be cleaned. Since the cleaning component 100 usually needs to rotate synchronously with the rotating member 200 to clean the ground, this setting makes the rotation direction of the rotating member 200 around the first axis R and the ground level, so as to keep the cleaning device 10 in contact or separation with the ground during rotation cleaning, and will not change in the height direction, resulting in poor cleaning effect or obstacle avoidance effect; and the cleaning component 100 can be flipped relative to the ground when rotating around the flip axis S to achieve lifting.

[0072] For easier understanding, see Figure 1 and Figure 2 ,as well as Fig.10 and Fig.11 , the descending position F1 can be set as the initial position of the cleaning part 110. When the third transmission part 320 moves around the first axis R driven by the second transmission part 310, it also abuts against the flipping part 120 along the radial direction G, pushing the flipping part 120 to rotate around the flipping axis S, and the flipping part 120 drives the cleaning part 110 to rotate around the flipping axis S synchronously, thereby flipping relative to the surface to be cleaned, thereby separating from the surface to be cleaned, and then leaving the descending position F1 and moving toward the ascending position F2.

[0073] In one embodiment, the center axis of the second transmission part 310 is the second axis L1, and the center axis of the third transmission part 320 is the third axis L2; ​​the second axis L1 is perpendicular to the first axis R and the third axis L2, respectively, and the third axis L2 forms a preset angle K with the flip axis S; when the first transmission part 210 drives the second transmission part 310 to rotate around the first axis R, the second transmission part 310 rotates around the second axis L1 synchronously, so that the third transmission part 320 drives the flip part 120 to flip around the flip axis S.

[0074] In one embodiment, the rising position F2 may include two. Since the rotation of the rotating member 200 around the first axis R is converted into the rotation of the cleaning assembly 100 around the flip axis S, when the rotating member 200 rotates forward, the cleaning assembly 100 can rotate forward around the flip axis S, and when the rotating member 200 rotates reversely, the cleaning assembly 100 can rotate reversely around the flip axis S. It can be understood that when the cleaning assembly 100 rotates forward, it can flip upward in a clockwise direction, thereby lifting to the first rising position F2, and when the cleaning assembly 100 rotates reversely, it can flip upward in a counterclockwise direction, thereby lifting to the second rising position F2. The descending position F1 is located between the two rising positions F2, and when the cleaning assembly 100 moves from the first rising position F2 to the second rising position F2, it passes through the descending position F1.

[0075] See also Figure 8 and Fig. 9 In one embodiment, one of the third transmission part 320 and the flip part 120 includes a transmission column 321, and the other one is provided with a transmission hole 1210; the transmission column 321 is passed through the transmission hole 1210 and is limited in radial direction.

[0076] For example, the third transmission part 320 is provided with a transmission column 321, and the flip part 120 is provided with a transmission hole 1210. The transmission column 321 is inserted into the transmission hole 1210 and is radially limited with the hole wall of the transmission hole 1210 so that the transmission column 321 abuts against the transmission hole 1210, driving the hole wall of the transmission hole 1210 to rotate around the flip axis S, thereby causing the cleaning component 100 to rotate around the flip axis S.

[0077] For example, the third transmission part 320 is provided with a transmission hole 1210, and the flip part 120 is provided with a transmission column 321. The transmission column 321 is inserted into the transmission hole 1210 and is limited radially with the hole wall of the transmission hole 1210. When the third transmission part 320 rotates driven by the second transmission part 310, the hole wall of the transmission hole 1210 abuts against the transmission column 321, driving the transmission column 321 to rotate around the flip axis S, thereby causing the cleaning component 100 to rotate around the flip axis S.

[0078] See also Figure 5 and Fig. 9 In one embodiment, the flip part 120 is provided with a transmission hole 1210, and the third transmission part 320 is provided with a transmission column 321; the central axis L3 of the transmission hole 1210 forms a preset angle K with the first axis R, so that when the transmission column 321 is passed through the transmission hole 1210, it forms a preset angle K with the first axis R; the preset angle K is an acute angle or an obtuse angle.

[0079] By setting the included angle between the central axis L3 of the transmission hole 1210 and the flip axis S to be the preset included angle K, after the transmission column 321 is assembled in the transmission hole 1210, the third axis L2 of the transmission column 321 coincides with the central axis L3 of the transmission hole 1210, so that the third axis L2 and the flip axis S form the preset included angle K. Since the first axis R and the flip axis S are perpendicular, the preset included angle K is set to an acute angle or an obtuse angle so that the third axis L2 does not coincide with the first axis R, thereby preventing the transmission column 321 from idling in the transmission hole 1210 and failing to form abutting force on the transmission hole 1210, thereby failing to drive the flip portion 120 to flip around the flip axis S.

[0080] The preset angle K may be that the third axis L2 and the direction in which the flipping portion 120 is connected to the cleaning portion 110 form an obtuse angle, thereby enabling flipping to be achieved.

[0081] In one embodiment, the cleaning component 100 also includes an extension portion 130, which is connected to the flip portion 120 and extends along the flip axis S in a direction opposite to the cleaning portion 110; the cleaning device 10 also includes a mounting shell 400, which is used to accommodate the cleaning component 100, the rotating member 200 and the lifting transmission member 300; wherein the mounting shell 400 is provided with two channels 401 in the rotation circumferential direction around the first axis R, the cleaning portion 110 and the extension portion 130 are respectively accommodated in the channels 401, and the cleaning portion 110 extends from the channels 401 to the outside of the mounting shell 400; the central axis of the channel 401 and the flip portion 120 form the flip axis S, and the cleaning component 100 is rotatably arranged in the channel 401.

[0082] The flip portion 120 has a direction extending toward the cleaning portion 110 and a direction away from the cleaning portion 110 along the flip axis S. Since the extension portion 130 is received in the channel 401 of the mounting shell 400, it abuts against the mounting shell 400 to limit the position, thereby improving stability.

[0083] The preset angle K may be an acute angle formed by the third axis L2 and the extension portion 130 , so that flipping can be achieved.

[0084] For ease of understanding, for example, extending toward the cleaning portion 110 is a forward direction, and extending away from the cleaning portion 110 is a reverse direction. The extension portion 130 extends in the reverse direction from the flip portion 120 and is received in the channel 401, which can reduce the weight difference between the two sides of the flip portion 120, which is beneficial to improving stability, and can also be limited with the channel 401 of the mounting shell 400 to prevent the flip portion 120 from moving on the first axis R.

[0085] See also Figure 6In one embodiment, the rotating member 200 is provided with a rotating surface 220, and the first transmission part 210 protrudes relative to the rotating surface 220 in a direction close to the cleaning component 100; a rotating space is formed between the rotating surface 220 and the first transmission part 210, so that the rotating member 200 can rotate around the first axis R; the first transmission part 210 is provided with an abutment groove, and the side wall of the abutment groove includes two first abutment surfaces 211 distributed at intervals in the rotation circumferential direction around the first axis R; the second transmission part 310 includes an abutment column 311, and the outer cylindrical surface of the abutment column 311 abuts against the two first abutment surfaces 211 on both sides of the rotation circumferential direction around the first axis R, and rotates around the first axis R when subjected to the abutment force of the first abutment surface 211, and rolls in the abutment groove around the second axis L1 driven by the third transmission part 320.

[0086] Among them, the rotating surface 220 can be set perpendicular to the first axis R, that is, it can be parallel to the surface to be cleaned or the horizontal plane. A rotating space is formed between the rotating surface 220 and the raised first transmission part 210 to avoid interference with the cleaning component 100, so that it can rotate around the first axis R.

[0087] Among them, the abutment groove of the first transmission part 210 can be provided as a combined groove having a circular arc bottom groove and a vertical side wall connected, and the two vertical side walls are formed into two first abutment surfaces 211, so that the second transmission part 310 can be subjected to the abutment force of the vertical side wall rotating around the first axis R, and can rotate along the second axis L1 relative to the circular arc bottom groove. However, it can be understood that the bottom groove can also be arranged horizontally, so that the abutment groove is a groove with a rectangular cross section, or a groove of other shapes, as long as the abutment groove can meet the requirements of abutting the second transmission part 310 when rotating around the first axis R, and the second transmission part 310 can rotate in the abutment groove. This embodiment does not limit the specific shape.

[0088] In order to realize the self-rotation of the second transmission part 310, the second transmission part 310 can be set to a cylindrical shape, or a contact column 311 close to a cylindrical shape. When the first transmission part 210 rotates forward around the first axis R, one of the two first contact surfaces 211 acts on one side of the outer cylindrical surface of the contact column 311, and when the first transmission part 210 rotates reversely around the first axis R, the other of the two first contact surfaces 211 acts on the other side of the outer cylindrical surface of the contact column 311, so that the second transmission part 310 can rotate around the first axis R under the action of the two first contact surfaces 211. When the second transmission part 310 rotates around the first axis R, the third transmission part 320 rotates with the second transmission part 310, but because the third transmission part 320 and the flipping part 120 form a preset angle K, the third transmission part 320 and the flipping part 120 abut against each other in the radial direction, so that the third transmission part 320 has a tendency to drive the flipping part 120 to flip, and because the abutment column 311 can rotate around the second axis L1, the third transmission part 320 can push the flipping part 120 to flip, thereby realizing the lifting and lowering of the cleaning component 100.

[0089] See also Figure 6 In one embodiment, a limiting surface 212 is provided on the side of the first transmission part 210 away from the first abutting surface 211; the limiting surface 212 is used to abut and limit with the cleaning component 100 or the mounting shell 400 when rotating around the first axis R to a preset position.

[0090] The shape of the limiting surface 212 may correspond to the first abutting surface 211, but may also be different, which is not specifically limited in this embodiment. The limiting surface 212 may abut against the mounting shell 400 or the cleaning component 100 when moving forward or reversely around the first axis R. The mounting shell 400 may be provided with a limiting structure, for example, the limiting structure on the mounting shell 400 may be limited during both forward and reverse movements, or the limiting structure may be limited during forward movement with the mounting shell 400 and during reverse movement with the cleaning component 100; or, the limiting structure may be limited during both forward and reverse movements with the cleaning component 100.

[0091] In one of the embodiments, a limiting surface 212 is provided to abut against and limit the cleaning component 100 when the cleaning component 100 moves forward or reversely around the first axis R. Since the flipping portion 120 of the cleaning component 100 has a portion extending toward the cleaning portion 110 and an opposite extension portion 130, the cleaning component 100 can be arranged in a rotating space formed by the rotating surface 220 and the first transmission portion 210. When the rotating surface 220 of the rotating member 200 rotates, the limiting surface 212 rotates synchronously with the rotating surface 220, and then when moving forward to a preset position, it is limited by the portion of the flipping portion 120 extending to the cleaning portion 110, and when moving reversely to the extension portion 130, it is respectively limited by the cleaning component 100, so that the flipping portion 120 is limited, the lifting transmission member 300 and the rotating member 200 no longer move relative to each other, and the cleaning component 100 and the lifting transmission member 300 can follow the rotating member 200 to perform a rotational movement around the first axis R synchronously. With this arrangement, there is no need to separately set a limiting structure on the mounting shell 400, and the cleaning assembly 100 can be limited by its own structure, thereby improving compactness, optimizing the use space of the cleaning device 10, and reducing production costs.

[0092] See also Figure 4 In one embodiment, the mounting shell 400 includes an upper cover 410 and a lower cover 420, which are fixedly connected; the lower cover 420 is provided with a rolling groove 402, and the rolling groove 402 is connected to the channel 401; the rolling groove 402 contacts the abutment column 311, and a movement gap is formed between the rolling groove 402 and the flip part 120.

[0093] The upper cover 410 and the lower cover 420 can be connected by snapping or bonding; the lower cover 420 can be provided with a rolling groove 402 on the inner side facing the upper cover 410, and the rolling groove 402 can be parallel to the surface to be cleaned and the rotating surface 220, and can be set as a circular groove. The abutting column 311 can abut against the rolling groove 402 under the action of gravity, and when the abutting column 311 rotates around the second axis L1, it is equivalent to rolling on the bottom surface of the rolling groove 402.

[0094] The movement gap enables the flipping portion 120 to rotate relative to the rolling groove 402 around the flipping axis S, thereby enabling the cleaning component 100 to be flipped and lifted.

[0095] See also Figure 7In one embodiment, the lifting transmission member 300 also includes a connecting portion 330, and two ends of the connecting portion 330 are respectively connected to the second transmission portion 310 and the third transmission portion 320; one end of the connecting portion 330 is connected to the second transmission portion 310 to form a right angle with the second transmission portion 310, and one end of the connecting portion 330 is connected to the third transmission portion 320 to form a right angle with the third transmission portion 320, and a right angle is formed between the two ends of the connecting portion 330, so that the central axis of the second transmission portion 310 is perpendicular to the central axis of the third transmission portion 320.

[0096] The second transmission part 310 and the third transmission part 320 are connected by the connecting part 330, and the connecting parts at both ends are formed at right angles, so that the central axis of the second transmission part 310 itself is perpendicular to the central axis of the third transmission part 320, and the radial movement of the third transmission part 320 is equivalent to the rotation of the second transmission part 310 around its own central axis, so that the third transmission part 320 and the second transmission part 310 rotate around the axis of the second transmission part 310 itself.

[0097] The central axis of the second transmission part may be the second axis L1, and the central axis of the third transmission part may be the third axis L2.

[0098] See also Figure 8 and Fig. 9 In one embodiment, two second transmission parts 310 are formed in the rotation circumferential direction around the first axis R, the two second transmission parts 310 are distributed on both sides of the flip axis S, and the extension lines of the two second transmission parts 310 coincide and are perpendicular to the first axis R; two first transmission parts 210 are formed in the rotation circumferential direction around the first axis R, and the two first transmission parts 210 are respectively used to abut against the corresponding two second transmission parts 310.

[0099] Among them, the second transmission part 310 and the first transmission part 210 are formed into two, the extension lines of which coincide and are perpendicular to the first axis R, and are distributed on both sides of the flip axis S, so that the force distribution on both sides of the flip axis S is uniform, avoiding noise or premature fatigue failure caused by abutment transmission on only one side.

[0100] For ease of understanding, the first axis R and the flip axis S intersect to form a center point, and the second transmission part 310 and the first transmission part 210 are symmetrically arranged relative to the center point, which effectively improves the stability of the transmission and avoids uneven force, thereby improving the working stability and service life of the cleaning device 10.

[0101] Corresponding to the aforementioned application function implementation device embodiment, the present application also provides a cleaning device 100, a cleaning device 1000 and corresponding embodiments.

[0102] See also Fig.12This embodiment also provides a cleaning device 20, including the cleaning device 10 as described above.

[0103] Among them, the cleaning device 20 can be a sweeping robot, a mopping robot, a sweeping and mopping robot, a window cleaning robot, etc. When the cleaning device 20 is a sweeping robot, the cleaning device can be a side-brushing cleaning device or a side-sweeping cleaning device.

[0104] The cleaning equipment 20 provided in this embodiment is provided with the above-mentioned cleaning device 10. Since the cleaning device 10 occupies less space in the vertical direction, a larger space can be obtained in the body of the cleaning equipment 20, which is beneficial to the module arrangement and design of the cleaning equipment 20, improves the space utilization rate of the cleaning equipment 20, and is also beneficial to reducing the volume of the cleaning equipment 20 and realizing a compact design. Moreover, since the size of the cleaning equipment 20 in the vertical direction is reduced, it is also beneficial to the passability of the cleaning equipment 20.
