Description

Technical Field

[0001] This application relates to the field of cleaning technology, and more particularly to a floor brush assembly and cleaning equipment. Background Technology

[0002] With the improvement of living standards and the development of technology, people have put forward higher requirements for the efficiency and cleanliness of floor cleaning in home and commercial environments. As a result, cleaning equipment such as vacuum cleaners, robot vacuum cleaners and floor scrubbers have emerged.

[0003] In related technologies, cleaning equipment includes a floor brush assembly, which typically includes a floor brush body and a roller brush unit. The roller brush unit includes a roller brush end cap and a roller brush body. One end of the roller brush body is rotatably connected to the roller brush end cap, and the roller brush end cap is fixed to the floor brush body by means of a snap-fit ​​and a slot to ensure the positional reliability of the roller brush body relative to the floor brush body. The other end of the roller brush body is rotatably connected to the floor brush body. The roller brush body has bristles on its peripheral wall, with the bristles exposed at the bottom of the floor brush body. The roller brush body can rotate around its own axis so that the bristles can rotate to contact the ground, thereby achieving the adsorption and cleaning of pollutants such as dust and hair on the ground.

[0004] However, in related technologies, when the roller brush unit is installed on the floor brush body, the buckle on the roller brush end cap needs to be precisely aligned with the slot on the floor brush body, which is inconvenient for installation. Furthermore, the buckle and slot are prone to wear or fatigue failure due to repeated disassembly and reassembly, resulting in poor reliability of the relative position between the roller brush unit and the floor brush body. Utility Model Content

[0005] In view of the above problems, this application provides a floor brush assembly and cleaning device that can realize automatic locking and positioning between the roller brush unit and the floor brush body, and is easy to disassemble and assemble, thereby improving the reliability of the relative position between the roller brush unit and the floor brush body, and thus improving the working reliability and stability of the device.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] A first aspect of this application provides a floor brush assembly, including a floor brush body and a roller brush unit, wherein the roller brush unit is disposed on the floor brush body; the roller brush unit includes a roller brush end cap and a roller brush body with bristles, the roller brush end cap being rotatably connected to one end of the floor brush body, one end of the roller brush body being rotatably connected to the roller brush end cap, and the other end being rotatably connected to the other end of the floor brush body, with some of the bristles of the roller brush exposed at the bottom of the floor brush body; the roller brush end cap having a first limiting structure and a first magnetic element, and the floor brush body having a second limiting structure and a second magnetic element; when the roller brush unit rotates relative to the floor brush body until the first limiting structure and the second limiting structure mutually limit and engage, the first magnetic element and the second magnetic element magnetically attract each other, so that the roller brush unit is in a locked state relative to the floor brush body.

[0008] In this embodiment, when the roller brush unit is placed on the mounting position of the floor brush body, it is only necessary to rotate the roller brush unit. When the first limiting structure on the roller brush end cap and the second limiting structure on the floor brush body mutually limit and cooperate with each other, the first magnetic component on the roller brush end cap and the second magnetic component on the floor brush body magnetically attract each other, thereby realizing the automatic locking operation. The user does not need to align precisely, the operation is convenient, time-saving and labor-saving, and repeated disassembly and assembly are not prone to wear or fatigue failure, thereby improving the reliability of the relative position between the roller brush unit and the floor brush body, and thus improving the working reliability and stability of the equipment.

[0009] In some alternative embodiments, the roller brush end cap has a rotary cylinder whose axis is aligned with the axis of the roller brush body, the floor brush body has a rotary hole that matches the rotary cylinder, the rotary cylinder is configured to rotatably engage with the rotary hole, wherein the first limiting structure is disposed on the outer peripheral wall of the rotary cylinder, and the second limiting structure is disposed on the inner peripheral wall of the rotary hole.

[0010] In this way, during installation, the rotary drum can be directly inserted into the rotary hole, and the first and second limiting structures can be engaged by rotating the entire roller brush unit. There is no need to precisely align the first and second limiting structures, which improves the ease of operation.

[0011] In some optional embodiments, along the circumference of the rotary cylinder, the outer peripheral wall of the rotary cylinder has a plurality of spaced limiting ribs, and the inner peripheral wall of the rotary hole has a limiting groove that matches each of the limiting ribs, wherein the limiting ribs are formed as the first limiting structure and the limiting grooves are formed as the second limiting structure.

[0012] In this way, the limiting rib and the limiting groove work together, resulting in a simple structure that is easy to process and has a low cost.

[0013] In some alternative embodiments, the floor brush assembly further includes a signal sensor fixed to the floor brush body;

[0014] When the roller brush unit moves to the locked state, a signal is generated between the signal sensing element and the first magnetic element.

[0015] In this way, the signal sensing device can detect in real time whether the roller brush unit is installed in place, thereby improving the operational reliability of the equipment and avoiding equipment malfunctions caused by improper installation of the roller brush unit.

[0016] In some alternative implementations, the signal sensing element is a Hall plate.

[0017] This improves the accuracy of determining whether the roller brush unit is installed correctly.

[0018] In some alternative implementations, the floor brush assembly further includes a micro switch disposed on the floor brush body, which is triggered when the roller brush unit moves to the locked state.

[0019] In this way, users can directly know whether the roller brush unit is installed correctly, and the cost is low.

[0020] In some alternative embodiments, the side of the roller brush end cap facing the brush body has a first positioning groove, and the first magnetic element is fixed in the first positioning groove.

[0021] This improves the reliability and stability of the installation position of the first magnetic component, thereby improving the reliability of the roller brush unit locking.

[0022] In some alternative embodiments, the first magnetic element is a magnet, and the second magnetic element is one of a metal plate or metal sheet that can be magnetically attracted by a magnet.

[0023] In this way, costs can be reduced without affecting the mutual magnetic interaction between the first and second magnetic components.

[0024] In some optional embodiments, the roller brush unit further includes a limiting cover and a bearing. The side of the roller brush end cover facing the roller brush body has a second positioning groove. The limiting cover is located between the roller brush end cover and the roller brush body and is detachably connected to the roller brush end cover. The limiting cover has a clearance hole. The bearing is sleeved on one end of the roller brush body and is installed in the second positioning groove through the clearance hole.

[0025] This limits the movement of the brush body, allowing it to rotate only around its own axis relative to the brush end cap, thereby improving the reliability and stability of the equipment operation.

[0026] A second aspect of this application provides a cleaning device, including a body and the floor brush assembly provided in the first aspect above.

[0027] The cleaning equipment provided in this application embodiment has the same beneficial effects as the floor brush assembly described above, and will not be repeated here.

[0028] In addition to the technical problems solved by the embodiments of this application, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that can be solved by the floor brush components and cleaning equipment provided by the embodiments of this application, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific implementation methods.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0055] This application provides a cleaning device, including but not limited to vacuum cleaners, robotic vacuum cleaners, floor scrubbers, etc. The cleaning device typically includes a body and a floor brush assembly connected to the body. The floor brush assembly typically includes a floor brush body and a roller brush unit. The roller brush unit includes a roller brush end cap and a roller brush body. One end of the roller brush body is rotatably connected to the roller brush end cap. The roller brush end cap is fixed to the floor brush body by a snap-fit ​​and slot-fitting method to achieve positional reliability of the roller brush body relative to the floor brush body. The other end of the roller brush body is rotatably connected to the floor brush body. The roller brush body has bristles on its peripheral wall, with the bristles exposed at the bottom of the floor brush body. The roller brush body can rotate around its own axis so that the bristles can rotate to contact the ground, thereby achieving the adsorption and cleaning of pollutants such as dust and hair on the ground.

[0056] However, when installing the roller brush unit onto the floor brush body, the clips on the roller brush end cap need to be precisely aligned with the slots on the floor brush body. This requires the user to find the correct alignment position for installation, leading to inconvenience. In addition, since the roller brush unit needs to be frequently disassembled to replace the brush bristles, cleaning cloth, etc., and to clean and maintain the roller brush unit, the clips and slots are prone to wear or fatigue failure during repeated disassembly and disassembly. The installation reliability and positional accuracy of the roller brush unit on the floor brush body are also affected by wear and other errors, resulting in poor reliability of the relative position between the roller brush unit and the floor brush body, which in turn affects the reliability and stability of the roller brush body during operation.

[0057] To overcome the above-mentioned defects, this application provides a floor brush assembly and cleaning equipment that allows users to install the roller brush unit without precise alignment, reducing the difficulty of disassembly and assembly, improving the ease of disassembly and assembly of the roller brush unit, saving time and effort, and preventing wear or fatigue failure even after repeated disassembly and assembly, thereby improving the reliability of the relative position between the roller brush unit and the floor brush body, and thus improving the working reliability and stability of the equipment.

[0058] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0059] Please refer to Figure 1 , Figure 2 and Figure 3 As shown, this application embodiment provides a cleaning device 1, which includes a body 20 and a floor brush assembly 10 located at the bottom of the body 20. The floor brush assembly 10 includes a floor brush body 100 and a roller brush unit 200, the roller brush unit 200 being detachably mounted on the floor brush body 100; wherein, as... Figure 3As shown, the roller brush unit 200 includes a roller brush end cap 210 and a roller brush body 220 with bristles. The roller brush end cap 210 is rotatably connected to one end of the floor brush body 100. One end of the roller brush body 220 is rotatably connected to the roller brush end cap 210, and the other end is rotatably connected to the other end of the floor brush body 100. Some of the bristles of the roller brush are exposed at the bottom of the floor brush body 100 so that the bristles come into contact with the floor to be cleaned. Thus, during the rolling of the roller brush body 220, the bristles pick up and sweep up the objects to be cleaned on the floor. The floor brush assembly 10 has a dust suction chamber and a negative pressure device inside. The side of the floor brush body 100 facing the roller brush body 220 has a dust suction port. The negative pressure device provides negative pressure to the dust suction chamber so that the dust particles and other debris picked up by the roller brush body 220 are sucked into the dust suction chamber through the dust suction port to achieve the purpose of dust suction.

[0060] In some embodiments, such as Figure 4 As shown, when the roller brush unit 200 and the floor brush body 100 are in a non-locking state, the roller brush end cap 210 in the roller brush unit 200 is rotatably connected to the floor brush body 100, so that the roller brush unit 200 can rotate relative to the floor brush body 100. When the first limiting structure 211 and the second limiting structure 110 are mutually limiting and engaged, the first magnetic element 300 on the roller brush end cap 210 and the second magnetic element 400 on the floor brush body 100 are magnetically attracted to each other, thereby making the roller brush unit 200 in a self-locking state, that is, the roller brush unit 200 and the floor brush body 100 automatically self-lock and position themselves (e.g., Figure 5 As shown in the image, installation can be completed without the user needing to perform precise positioning.

[0061] Therefore, in this embodiment, by providing a first limiting structure 211 and a first magnetic element 300 on the roller brush end cap 210 of the roller brush unit 200, and providing a second limiting structure 110 and a second magnetic element 400 on the floor brush body 100, and by allowing the roller brush unit 200 to rotate relative to the floor brush body 100, when the roller brush unit 200 is rotatably connected to the floor brush body 100, it is only necessary to rotate the roller brush unit 200 to rotate it to the first limiting structure 211 on the roller brush end cap 210. When the first magnetic component 300 on the roller brush end cap 210 and the second magnetic component 400 on the brush body 100 cooperate with each other, they magnetically attract each other, thus completing the automatic locking operation. In this way, the user does not need to align precisely, making the operation convenient, saving time and effort. Repeated disassembly and assembly are less likely to cause wear or fatigue failure, thereby improving the reliability of the relative position between the roller brush unit 200 and the brush body 100, and thus improving the working reliability and stability of the equipment.

[0062] In some embodiments, such as Figure 2 and Figure 3As shown, the roller brush end cap 210 has a rotating cylinder 212, the axis of which is aligned with the axis of the roller brush body 220. The floor brush body 100 has a rotating hole 120 that matches the rotating cylinder 212. The rotating cylinder 212 is configured to rotatably engage with the rotating hole 120. A first limiting structure 211 is disposed on the outer peripheral wall of the rotating cylinder 212, and a second limiting structure 110 is disposed on the inner peripheral wall of the rotating hole 120. Thus, during installation, the rotating cylinder 212 extends directly into the rotating hole 120. By rotating the entire roller brush unit 200, when the first limiting structure 211 and the second limiting structure 110 mutually limit and engage, the first magnetic component 300 and the second magnetic component 400 magnetically attract each other, achieving automatic self-locking. Users do not need to precisely align the first limiting structure 211 and the second limiting structure 110, improving operational convenience.

[0063] In other words, during installation, simply place the rotary drum 212 into the rotary hole 120 and rotate the roller brush unit 200 to limit the mutual positioning of the first limiting structure 211 and the second limiting structure 110; for example, the first limiting structure 211 and the second limiting structure 110 abut against each other to restrict the rotation of the roller brush unit 200.

[0064] like Figure 2 and Figure 3 As shown, along the circumference of the rotary cylinder 212, the outer peripheral wall of the rotary cylinder 212 has multiple spaced limiting ribs, and the inner peripheral wall of the rotary hole 120 has limiting grooves that match each limiting rib. The limiting ribs are formed as a first limiting structure 211, and the limiting grooves are formed as a second limiting structure 110. The extending direction of the limiting grooves is consistent with the rotation direction of the roller brush unit 200. Thus, when the roller brush unit 200 is installed, when it is rotated until the limiting ribs abut against the groove wall of the limiting groove, the first magnetic component 300 and the second magnetic component 400 are just at the position where they can magnetically attract each other, achieving magnetic attraction and realizing self-locking of the roller brush unit 200. In addition, the first limiting structure 211 and the second limiting structure 110 have simple structures, are easy to process, and have low cost.

[0065] It is understandable that when the roller brush unit 200 is not rotated to the self-locking position, the limiting rib is located within the limiting groove (e.g., Figure 6 , Figure 7 , Figure 12 and Figure 13 As shown in the figure, it moves along the extension trajectory of the limiting groove. In this way, the limiting groove can guide the limiting rib, thereby improving the accuracy of the rotation path of the roller brush unit 200.

[0066] Additionally, to check whether the roller brush unit 200 is properly installed, in some embodiments, please refer to... Figure 8 , Figure 9 , Figure 12 and Figure 13 As shown, the floor brush assembly 10 also includes a signal sensor 500, which is fixed to the floor brush body 100. When the roller brush unit 200 moves to the locked state, the signal sensor 500 and the first magnetic component 300 generate a signal and feed it back to the control system of the cleaning equipment 1. The control system can feed the information back to the user through a display or indicator light so that the user can clearly know whether the roller brush unit 200 is installed in place. In this way, the signal sensor 500 can be used to know in real time whether the roller brush unit 200 is installed in place, which improves the operational reliability of the equipment and avoids equipment malfunctions caused by the roller brush unit 200 not being installed in place.

[0067] For example, the signal sensing element 500 is a Hall plate, which integrates Hall elements. The Hall elements can detect the adsorption state between the first magnetic element 300 and the second magnetic element 400, thereby determining whether the roller brush unit 200 is installed in place. This improves the accuracy of whether the roller brush unit 200 is installed in place.

[0068] In some other embodiments, the floor brush assembly 10 also includes a micro switch, which is disposed on the floor brush body 100. When the roller brush unit 200 moves to the locked state, the micro switch is triggered. When the micro switch is triggered, it can be known by an indicator light, a buzzer, or by direct observation by the user. In this way, the user can directly know whether the roller brush unit 200 is installed in place, and the cost is low.

[0069] Please refer to Figure 10 and Figure 11 As shown, the roller brush end cap 210 has a first positioning groove 213 on the side facing the brush body 100. The first magnetic component 300 is fixed in the first positioning groove 213. The outline shape of the first positioning groove 213 matches the outline shape of the first magnetic component 300 so that the first magnetic component 300 is embedded in the first positioning groove 213, that is, the peripheral wall of the first magnetic component 300 abuts against the inner peripheral wall of the first positioning groove 213. This improves the reliability and stability of the installation position of the first magnetic component 300, thereby improving the reliability of locking the roller brush unit 200.

[0070] For example, if the outline of the first magnetic component 300 is circular, then the first positioning groove 213 is a circular positioning groove that matches the first magnetic component 300. The second magnetic component 400 can be any shape, such as circular, rectangular, or elliptical, and can be fixed to the floor brush body 100 by means of bonding, embedding, snapping, threading, etc., without specific limitations.

[0071] For example, the first magnetic component 300 is a magnet, and the second magnetic component 400 is a metal plate or sheet that can be magnetically attracted by the magnet. This reduces costs without affecting the mutual magnetic interaction between the first magnetic component 300 and the second magnetic component 400. Figure 2 , Figure 4 As shown, the second magnetic element 400 is a rectangular iron sheet, such as... Figure 3 and Figure 11 As shown, the first magnetic element 300 is a circular magnet.

[0072] Please continue to refer to Figure 3 , Figure 10 and Figure 11 As shown, the roller brush unit 200 also includes a limiting cover 230 and a bearing 240. The roller brush end cover 210 has a second positioning groove 214 on the side facing the roller brush body 220. The limiting cover 230 is located between the roller brush end cover 210 and the roller brush body 220 and is detachably connected to the roller brush end cover 210. The limiting cover 230 has a clearance hole 231. The bearing 240 is sleeved on one end of the roller brush body 220 and passes through the clearance hole 231 and is installed in the second positioning groove 214. In this way, the roller brush body 220 is limited so that the roller brush body 220 can only rotate around its own axis relative to the roller brush end cover 210, thereby improving the reliability and stability of the equipment operation.

[0073] During installation, the bearing 240 is pressed into the second positioning groove 214. The side of the roller brush end cap 210 facing the roller brush body 220 has multiple threaded posts 215. The limiting cap 230 has multiple fixing holes and a clearance hole 231 to avoid the bearing 240. The limiting cap 230 is installed on the side of the roller brush end cap 210 facing the roller brush body 220 and is threadedly connected to the corresponding threaded posts 215 through the fixing holes by a threaded connector. The end shaft of the roller brush body 220 is connected to the bearing 240 so that the roller brush body 220 can only rotate around its own axis relative to the roller brush end cap 210, thus completing the assembly of the roller brush unit 200.

[0074] Understandably, the roller brush end cap 210 is installed at one end of the floor brush body 100, while the second magnetic component 400 is installed on the outer side wall of the floor brush body 100 facing the roller brush end cap 210. When the rotating cylinder 212 of the roller brush end cap 210 extends into the rotating hole 120 on the floor brush body 100, as... Figure 4As shown, the roller brush unit 200 is rotated counterclockwise until the limiting rib on the outer peripheral wall of the rotary cylinder 212 abuts against the groove wall of the limiting groove on the inner peripheral wall of the rotary hole 120. At this time, the first magnetic component 300 and the second magnetic component 400 are magnetically attracted to each other. At this time, the Hall plate installed on the floor brush body 100 can detect the attraction state of the first magnetic component 300 and the second magnetic component 400, realizing the installation of the roller brush unit 200 onto the floor brush body 100. It can also accurately detect whether the installation is in place, and the user does not need to perform precise alignment. When disassembling, simply rotate the roller brush unit 200 in the opposite direction to move the first magnetic component 300 away from the second magnetic component 400, thereby releasing the magnetic attraction between the two and unlocking. The disassembly and assembly method is simple and convenient, and repeated disassembly and assembly will not cause wear and fatigue failure, thereby improving the reliability of the relative position between the roller brush unit 200 and the floor brush body 100, and thus improving the working reliability and stability of the equipment.
