Description

Technical Field

[0001] This application relates to the field of cleaning technology, and in particular to a cleaning mechanism, floor cleaning equipment and cleaning system. Background Technology

[0002] As living standards improve, smart home cleaning devices, such as smart floor scrubbers, are gaining wider acceptance. Smart floor scrubbers combine sweeping and mopping functions, significantly improving cleaning efficiency.

[0003] One of the key components of a floor scrubber is the cleaning assembly, which comes into close contact with the surface to be cleaned to remove dirt and grime. The cleaning assembly includes the main cleaning component and the squeegee, which is positioned to one side of the main cleaning component along the direction of the scrubber's movement. As the scrubber moves, the squeegee may fold, causing it to be pressed against the surface by the scrubber's body. During this movement, the friction between the squeegee and the floor can produce noise. Utility Model Content

[0004] One object of this application is to provide a cleaning mechanism, floor cleaning equipment and cleaning system that can improve the problem of abnormal noise caused by the scraper blades turning over during the operation of the cleaning mechanism.

[0005] This application provides a cleaning mechanism, including a housing, a cleaning component, and a scraper. The housing has an internal receiving cavity and includes a bottom surface facing the surface to be cleaned. The bottom surface has an opening and a clearance groove. The opening communicates with the receiving cavity, and the clearance groove is located on one side of the opening and communicates with the opening. The cleaning component is rotatably disposed within the receiving cavity and partially protrudes from the opening. The scraper is connected to the housing and includes a scraping stop portion that protrudes from the opening and is used to contact the surface to be cleaned. The scraping stop portion is deformable and can be bent toward the clearance groove, which is configured to receive the bent portion of the scraping stop portion.

[0006] The cleaning mechanism provided in this application improves the problem of abnormal noise caused by friction between the bent part of the scraper and the surface to be cleaned by setting a relief groove on the bottom surface that communicates with the opening, and setting a scraper that can be bent in the direction of the relief groove. This is so that during the movement of the cleaning mechanism, the bent part of the scraper can be stored in the relief groove and not pressed by the bottom surface on the surface to be cleaned.

[0007] In some alternative implementations, the depth of the clearance groove is greater than or equal to the thickness at the maximum thickness of the scraper, which allows the entire bent portion of the scraper to be accommodated in the clearance groove, further improving the problem of abnormal noise caused by friction between the bent portion of the scraper and the surface to be cleaned.

[0008] In some alternative implementations, the width of the clearance groove is greater than or equal to the height of the scraper, which allows the entire bent portion of the scraper to be accommodated in the clearance groove, further improving the problem of abnormal noise caused by friction between the bent portion of the scraper and the surface to be cleaned.

[0009] In some alternative embodiments, the scraper includes a side facing the clearance groove, and the side has a protrusion extending along the length of the scraper. The protrusion helps the scraper prevent debris swept by the cleaning component from leaking to the side of the scraper away from the cleaning component, and at the same time helps the scraper guide the debris swept by the cleaning component into the receiving cavity.

[0010] In some alternative implementations, when the scraper is in its natural state, the scraper is set in an inclined state, with the scraper tilted away from the clearance groove. This helps the scraper block the garbage swept by the cleaning component to leak to the side away from the cleaning component, and at the same time helps the scraper block guide the garbage swept by the cleaning component into the receiving cavity.

[0011] In some alternative implementations, the squeegee is made of a flexible material to prevent it from scratching the surface to be cleaned.

[0012] In some alternative implementations, the cleaning mechanism includes a suction device that communicates with an opening to generate negative pressure at the opening, allowing the debris swept up by the cleaning components to be sucked into the receiving cavity through the opening, thereby improving cleaning efficiency.

[0013] In some alternative implementations, the clearance groove is located behind the opening along the forward direction of the cleaning mechanism.

[0014] In some alternative implementations, the scraper is located behind the cleaning component along the forward direction of the cleaning mechanism, so that the scraper can prevent the cleaning debris from leaking behind the scraper as the cleaning mechanism moves forward.

[0015] A second aspect of this application provides a floor cleaning device, including a body, wheels, and any of the aforementioned cleaning mechanisms. The housing is disposed on the body, or the housing is part of the body. The wheels are disposed on the body to allow the floor cleaning device to be moved.

[0016] In some alternative embodiments, the floor cleaning equipment also includes a sweeping component positioned in front of the opening in the forward direction of the floor cleaning equipment.

[0017] In some alternative implementations, the floor cleaning equipment also includes a mop, which is positioned behind the clearance groove in the forward direction of the floor cleaning equipment.

[0018] In some alternative embodiments, the floor cleaning equipment includes a caster wheel assembly disposed on the machine body. The caster wheel assembly includes an axle and a wheel body, with the axle rotatably passing through the wheel body. A storage space is provided between the wheel body and the axle. The storage space is used to collect debris, hair, or particles that get caught in the gap between the axle and the wheel body, thus improving the problem of abnormal noise caused by friction between the tangled debris and the axle and wheel body.

[0019] In some alternative embodiments, the storage space is a groove provided on the circumferential surface of the axle and / or the inner surface of the wheel body.

[0020] In some alternative embodiments, the caster assembly also includes a shield located at the end of the axle, with a labyrinth seal gap between the shield and the wheel body to prevent tangled material from entering the gap between the axle and the wheel body, thereby improving the problem of abnormal noise caused by friction between the tangled material and the axle and wheel body.

[0021] A third aspect of this application provides a cleaning system, including any of the above-mentioned ground cleaning equipment and a base station used in conjunction with the ground cleaning equipment, wherein the ground cleaning equipment is maintained within the base station.

They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0034] Some embodiments of this application will now be described with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] Please see Figure 1 and Figure 2 One embodiment of this application provides a cleaning mechanism 1, including a housing 10, a cleaning component 20, and a scraper 30.

[0036] The housing 10 has an internal receiving cavity 11. The housing 10 includes a bottom surface 12 facing the surface to be cleaned. The bottom surface 12 has an opening 121 and a clearance groove 122. The opening 121 communicates with the receiving cavity 11, and the clearance groove 122 is located on one side of the opening 121 and communicates with it. The housing 10 includes a clearance bottom wall 1221 and a clearance side wall 1222 located at the clearance groove 122. One end of the clearance side wall 1222 is connected to the clearance bottom wall 1221, and the other end is connected to the bottom surface 12. The clearance bottom wall 1221 and the clearance side wall 1222 form the clearance groove 122. At least one side of the clearance bottom wall 1221 does not have the clearance side wall 1222, so that the clearance groove 122 communicates directly with the opening 121.

[0037] The cleaning component 20 is rotatably disposed within the receiving cavity 11 and protrudes from the opening 121. When the cleaning component 20 rotates, it can contact the surface to be cleaned through the opening 121, thereby cleaning the surface. In this embodiment, the cleaning component 20 is a component for sweeping, such as a roller brush. In another embodiment, the cleaning component 20 can be a component for mopping, such as a roller with a mop cloth on its surface.

[0038] The scraper 30 is connected to the housing 10. The scraper 30 includes a scraper baffle 31, which protrudes from the bottom wall 1221 and protrudes from the opening 121. The scraper baffle 31 is used to contact the surface to be cleaned. The scraper baffle 31 protruding from the opening 121 is located on the side of the cleaning member 20 protruding from the opening 121. When the cleaning member 20 cleans the surface to be cleaned, the scraper baffle 31 contacts the surface to be cleaned. On the one hand, the scraper baffle 31 prevents the debris (such as dust, hair, etc.) cleaned by the cleaning member 20 from leaking to the side of the scraper baffle 31 away from the cleaning member 20. On the other hand, it guides the debris cleaned by the cleaning member 20 so that the debris can smoothly enter the receiving cavity 11 through the opening 121.

[0039] When the scraper 31 encounters an obstacle, such as when it enters a tile grout line, it may fold over, causing it to be pressed against the surface to be cleaned by the bottom surface 12 of the housing 10. During the movement of the cleaning mechanism 1, the scraper 31 rubs against the surface to be cleaned, generating abnormal noise. The scraper 31 is deformable and can be bent towards the relief groove 122. The relief groove 122 is configured to accommodate the bent portion of the scraper 31 so that the scraper 31 is not pressed against the surface to be cleaned by the bottom surface 12 after bending, thus improving the problem of abnormal noise caused by the friction between the bent portion of the scraper 31 and the surface to be cleaned.

[0040] In some embodiments, the scraper 30 contacts the edge of the clearance wall 1221. During the movement of the cleaning mechanism 1, the clearance wall 1221 can support the scraper 30, reducing the risk of the scraper 30 flipping over when it encounters an obstacle.

[0041] In some embodiments, along the forward direction of the cleaning mechanism 1, the scraper 30 is located behind the cleaning component 20, so that as the cleaning mechanism 1 moves forward, the scraper 31 can prevent the garbage swept by the cleaning component 20 from leaking to the rear of the scraper 31.

[0042] In some embodiments, along the forward direction of the cleaning mechanism 1, the clearance groove 122 is located behind the opening 121, so that after the scraper 30 located behind the cleaning member 20 is deformed, the bent portion of the scraper block 31 can be smoothly accommodated in the clearance groove 122.

[0043] Please see Figure 2 The scraper blade 30 is partially disposed within the receiving cavity 11 and snaps into the housing 10. The cavity wall of the receiving cavity 11 has a slot 110, and the scraper blade 30 has a locking block 32, which snaps into the slot 110. It can be understood that the slot 110 can be located on the scraper blade 30, and the locking block 32 can be located on the cavity wall of the receiving cavity 11. The scraper blade 30 and the housing 10 are connected by a snap-fit ​​mechanism, facilitating the assembly and disassembly of the scraper blade 30. In another embodiment, the scraper blade 30 is integrally formed with the clearance bottom wall 1221 for easier processing.

[0044] In some embodiments, the depth of the clearance groove 122 is greater than or equal to the thickness at the maximum thickness of the scraper portion 31. The depth of the clearance groove 122 refers to the vertical distance between the clearance bottom wall 1221 and the bottom surface 12. When the scraper portion 31 is bent, the thickness direction of the scraper portion 31 is approximately the same as the depth direction of the clearance groove 122. By setting the depth of the clearance groove 122 to be greater than or equal to the maximum thickness of the scraper portion 31, the entire bent portion of the scraper portion 31 can be contained within the clearance groove 122 in the depth direction of the clearance groove 122, without protruding from the bottom surface 12, further improving the problem of abnormal noise caused by friction between the bent portion of the scraper portion 31 and the surface to be cleaned.

[0045] In some embodiments, the width of the clearance groove 122 is greater than or equal to the height of the scraper portion 31. The width of the clearance groove 122 refers to the width of the clearance bottom wall 1221 in the direction toward the scraper portion 31. The height of the scraper portion 31 refers to the length from the edge of the scraper portion 31 to the position where the scraper portion 31 is flush with the clearance bottom wall 1221. By setting the width of the clearance groove 122 to be greater than or equal to the height of the scraper portion 31, the entire bent portion of the scraper portion 31 can be accommodated in the clearance groove 122 in the width direction, which helps to prevent the bent portion of the scraper portion 31 from protruding from the bottom surface 12, and further improves the problem of abnormal noise caused by friction between the bent portion of the scraper portion 31 and the surface to be cleaned.

[0046] Please see Figure 2 When the scraper 30 is in its natural state, it is tilted, with the scraper 30 tilted away from the clearance groove 122. In this way, the scraper 30 is tilted towards the center of the opening 121, which makes it easier for the scraper baffle 31 to prevent the garbage swept by the cleaning member 20 from leaking to the side of the scraper 30 away from the cleaning member 20, and at the same time, it makes it easier for the scraper baffle 31 to guide the garbage swept by the cleaning member 20 into the receiving cavity 11.

[0047] Please see Figure 1 and Figure 2 The scraper baffle 31 includes a side surface 311 facing the relief groove 122, and the side surface 311 is provided with a protrusion 33 extending along the length direction of the scraper 30. The protrusion 33 is used to contact the surface to be cleaned. When the cleaning mechanism 1 moves back and forth, the scraper baffle 31 can deform and bend away from the relief groove 122, so that the apex of the protrusion 33 contacts the surface to be cleaned 122. This makes it easier for the scraper baffle 31 to prevent the debris swept by the cleaning component 20 from leaking to the side of the scraper 30 away from the cleaning component 20, and at the same time, it makes it easier for the scraper baffle 31 to guide the debris swept by the cleaning component 20 into the receiving cavity 11.

[0048] Please see Figure 2 The protrusion 33 includes a first inclined surface 331 and a second inclined surface 332, which are connected and angled together. The first inclined surface 331 is connected to the edge of the scraper portion 31. The connection point between the first inclined surface 331 and the second inclined surface 332 serves as the apex of the protrusion 33. This allows the scraper portion 31 to bend away from the clearance groove 122, making the apex of the protrusion 33 contact the surface 122 to be cleaned.

[0049] In some embodiments, the scraper 30 is made of a flexible material to prevent it from scratching the surface to be cleaned when the moving cleaning mechanism 1 cleans the surface. The scraper 30 may be made of rubber.

[0050] Please see Figure 1The cleaning mechanism 1 includes a suction device 40, which is connected to an opening 121 to generate a negative pressure at the opening 121, so that the garbage swept up by the cleaning component 20 can be sucked into the receiving cavity 11 through the opening 121, thereby improving cleaning efficiency. The suction device 40 can be a fan.

[0051] Please see Figure 3 This application provides a floor cleaning device 2 according to one embodiment, including a body 50, wheels 60, and a cleaning mechanism 1 as described in any of the preceding embodiments. The housing 10 is part of the body 50, and a receiving cavity 11 is disposed inside the body 50. In another embodiment, the housing 10 is separately formed from the body 50, and the housing 10 is disposed on the body 50. The wheels 60 are disposed at the bottom of the body 50 to allow the floor cleaning device 2 to move. The floor cleaning device 2 moves under the drive of the wheels 60.

[0052] Please see Figure 3 The floor cleaning device 2 also includes a sweeping component 70, which is located at the bottom of the body 50 and is used to sweep the surface to be cleaned. In the forward direction of the floor cleaning device 2, the sweeping component 70 is positioned in front of the opening 121. Driven by the traveling wheels 60, the floor cleaning device 2 moves forward. During this forward movement, the sweeping component 70 sweeps debris to the area below the opening 121, and the rotating cleaning component 20 carries the debris below the opening 121 into the receiving cavity 11.

[0053] Please see Figure 3 The floor cleaning device 2 also includes a mopping component 80, which is located at the bottom of the body 50 and is used to mop the surface to be cleaned. In the forward direction of the floor cleaning device 2, the mopping component 80 is located behind the clearance groove 122, so that the floor cleaning device 2 can achieve the effect of sweeping first and then mopping when cleaning the surface to be cleaned.

[0054] Please see Figure 3 The floor cleaning equipment 2 includes a caster wheel assembly 90, which is located at the bottom of the body 50 and is used to assist in changing the direction of the floor cleaning equipment 2.

[0055] Please see Figures 4 to 6 The caster wheel assembly 90 includes an axle 91 and a wheel body 92, with the axle 91 rotatably mounted on the wheel body 92. The circumferential surface of the axle 91 rotatably engages with the inner surface of the wheel body 92. A storage space 901 is provided between the wheel body 92 and the axle 91. During the movement of the caster wheel assembly 90, the storage space 901 is used to collect debris, hair, or particles that become entangled in the gap between the axle 91 and the wheel body 92, thus mitigating the problem of abnormal noise caused by friction between the entangled material and the axle 91 and the wheel body 92.

[0056] Please see Figure 6Storage space 901 is a groove provided on the circumferential surface of axle 91. In another embodiment, storage space 901 can be a groove provided on the inner surface of wheel body 92. In yet another embodiment, storage space 901 can be a groove provided on the circumferential surface of axle 91 and a groove provided on the inner surface of wheel body 92, wherein the groove on axle 91 and the groove on wheel body 92 can communicate to accommodate more wound material.

[0057] Please see Figure 5 and Figure 6 The caster wheel assembly 90 includes a shield 93 disposed at the end of the axle 91. The shield 93 can be sleeved onto the end of the axle 91. The shield 93 and the axle 91 can be fixed by an insert injection molding process. During the movement of the caster wheel assembly 90, the shield 93 can prevent tangled objects from getting caught in the gap between the axle 91 and the wheel body 92.

[0058] Please see Figure 6 A labyrinth seal gap 902 is formed between the shielding member 93 and the wheel body 92. The labyrinth seal gap 902 is arranged in a labyrinthine pattern and can be formed by multiple gaps that are bent and connected. This labyrinth seal gap 902 can prevent entangled objects from entering the gap between the axle 91 and the wheel body 92, and ensures that the shielding member 93 does not rotate with the wheel body 92 during rotation, thus not interfering with the movement of the wheel body 92.

[0059] Please see Figures 4 to 6 The caster wheel assembly 90 includes a bracket 94 and a mounting base 95. The mounting base 95 is disposed on the body 50, and the bracket 94 is rotatably mounted on the mounting base 95. The bracket 94 includes a top plate 941 and two side plates 942 connected to the edge of the top plate 941 and opposite to each other. The two ends of the axle 91 are respectively mounted on the two side plates 942 and fixed to the side plates 942 by a blocking member 93, so that the blocking member 93 and the axle 91 can be stably connected to the bracket 94 without relative sliding or abnormal noise.

[0060] Please see Figure 7 This application provides a cleaning system 3, comprising a floor cleaning device 2 as described in any of the above embodiments and a base station 310 used in conjunction with the floor cleaning device 2. The floor cleaning device 2 is maintained within the base station 310. The base station 310 is primarily used for charging the cleaning device 2, or for cleaning, drying, etc.

[0061] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
