Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a floor brush assembly and cleaning equipment. Background Technology

[0002] Floor scrubbers, vacuum cleaners, and other cleaning equipment are widely used in homes and commercial environments to clean dust, debris, hair, and other dirt from floors. They achieve their cleaning function by using a motor to drive a rotating brush and coordinating with airflow to achieve the same effect, and have become an important part of modern cleaning tools.

[0003] In related technologies, the floor brush assembly of cleaning equipment typically includes a floor brush body, a roller brush rotatably mounted on the floor brush body, and a motor that drives the roller brush to rotate. The two ends of the roller brush are supported on the floor brush body by bearing structures. During operation, the motor drives the roller brush to rotate at high speed. Airflow carrying dust, hair, and other dirt enters from the suction ports on both sides of the roller brush and is sucked into the dust collection chamber inside the cleaning equipment through the dust suction port located near the middle area of ​​the roller brush.

[0004] However, in related technologies, due to the relative rotation between the roller brush and the floor brush body, hair, fibers and other easily tangled objects sucked in at both ends will get tangled at both ends of the roller brush, which will increase the rotational resistance of the roller brush and cause the motor load to rise sharply. This not only affects the cleaning efficiency, but may also cause the motor to overload and stop or be damaged, reducing the reliability and service life of the product. Utility Model Content

[0005] In view of the above problems, this application provides a floor brush assembly and cleaning device that can prevent hair and other entangled objects from getting tangled at both ends of the roller brush, thereby improving the anti-tangling performance of the device.

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

[0007] This application provides a floor brush assembly, including: a floor brush body, a roller brush, and a drive motor. The floor brush body has a mounting cavity with an open bottom. The roller brush is rotatably mounted in the mounting cavity and connected to the drive motor. The drive motor drives the roller brush to rotate around its own axis. A portion of the roller brush structure is exposed outside the floor brush body through the open cavity to contact the surface to be cleaned. The floor brush assembly also includes two shielding members, which are respectively disposed at both ends of the roller brush along its axial direction. Each shielding member is fixed to the floor brush body and located near the bottom of the corresponding end of the roller brush, and cooperates with the outer peripheral wall of the corresponding end of the roller brush.

[0008] Each of the shielding members is configured to shield the assembly gap between the end face of the corresponding end of the roller brush and the adjacent sidewall of the mounting cavity.

[0009] In the floor brush assembly provided in this application embodiment, shielding members are respectively provided at both ends of the roller brush. The shielding members are fixedly connected to the floor brush body and are located near the bottom of the corresponding end of the roller brush. They cooperate with the outer peripheral wall of the corresponding end of the roller brush to shield the assembly gap between the side walls of the mounting cavity at both ends of the roller brush and the end face of the corresponding end of the roller brush. In this way, when the equipment is cleaning, hair and other entangled objects are blocked by the shielding members, so that when the hair and other entangled objects move with the airflow direction, they are not easy to be rolled into and wrapped around the two ends of the roller brush. This reduces the risk of hair and other entangled objects easily getting wrapped around the two ends of the roller brush, improves the anti-winding performance of the equipment, effectively prevents the roller brush rotation resistance from increasing, and improves the cleaning effect and efficiency of the roller brush, extending the reliability and service life of the product.

[0010] In some alternative embodiments, the distance between each of the shielding members and the central axis of the brush along the radial direction of the brush is less than the distance between the outer peripheral surface of the brush and the central axis of the brush.

[0011] In this way, the interference fit between the shield and the brush bristles further prevents hair and other tangled objects from getting caught between the brush and the shield, thus further improving the anti-tangling performance.

[0012] In some alternative embodiments, the difference between the distance from the outer peripheral surface of the roller brush to the central axis of the roller brush and the distance from each of the shielding members to the central axis of the roller brush is 1 to 3 mm along the radial direction of the roller brush.

[0013] This effectively prevents hair and other tangled objects from getting caught between the roller brush and the shielding parts. At the same time, it avoids the shielding parts increasing the resistance to the rotation of the roller brush, ensuring the smooth rotation of the roller brush.

[0014] In some alternative embodiments, along the radial direction of the roller brush, the projection of each of the blocking members overlaps with the projection of the corresponding end of the roller brush, and the size of the overlapping area in the axial direction of the roller brush is 1~3mm.

[0015] In this way, the axial fit between the shield and the roller brush is an interference fit, forming an effective barrier between the end of the roller brush and the shield. This effectively prevents hair and other entangled objects from being rolled into the space between the roller brush and the shield. In addition, the interference fit size is set between 1 and 3 mm, which can prevent the shield from increasing the resistance to the rotation of the roller brush and ensure the smoothness of the roller brush rotation.

[0016] In some alternative embodiments, the shielding member is a plate-like structure.

[0017] In this way, the flat surface of the plate-shaped shield can effectively prevent hair and debris from entering the interior of the floor brush assembly, and the structure is simple, easy to process, and low in cost.

[0018] In some alternative implementations, the floor brush assembly further includes: a transmission bracket, a first bearing, and a transmission component;

[0019] The roller brush has a first roller brush joint at one end along the axial direction. The drive motor and the transmission bracket are arranged adjacent to the first roller brush joint, and the power output end of the drive motor is connected to the input end of the transmission component, and the power output end of the transmission component is connected to the first roller brush joint.

[0020] The transmission bracket is fixed on the brush body, and the transmission bracket has a first accommodating space. The first roller brush connector is coaxially connected to the first bearing and is accommodated in the first accommodating space.

[0021] In this way, by embedding the first roller brush connector within the first accommodating space, hair and other entangled objects can be prevented from getting tangled at the first roller brush connector, thereby further improving the anti-tangling performance of the equipment.

[0022] In some alternative embodiments, the floor brush assembly further includes a bearing bracket and a second bearing, the other end of the roller brush having a second roller brush connector along the axial direction, the bearing bracket being fixed to the floor brush body adjacent to the second roller brush connector, the bearing bracket having a second receiving space, the second roller brush connector being coaxially connected to the second bearing and received within the second receiving space.

[0023] In this way, by embedding the second roller brush connector within the second accommodating space, hair and other entangled objects can be prevented from getting tangled at the second roller brush connector, thereby further improving the anti-tangling performance of the equipment.

[0024] In some alternative embodiments, the brush assembly further includes a handle mounted on the bearing bracket, and a shield located on the same side of the roller brush axis as the handle is connected to the handle.

[0025] In this way, while enabling functions such as easy disassembly of the bearing bracket, the device also provides a supporting foundation for the shielding component located on the same side as the roller brush, eliminating the need for additional support structures for the shielding component, simplifying the device structure and reducing manufacturing costs.

[0026] In some alternative embodiments, the handle and the shield connected to the handle are an integral structure.

[0027] This reduces installation steps and lowers costs.

[0028] A second aspect of this application provides a cleaning device, including a floor brush assembly as provided in the first aspect.

[0029] The cleaning equipment provided in this application embodiment has the same beneficial effects as the floor brush assembly provided in the above embodiment, and will not be described again here.

[0058] 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.

[0059] This application provides a cleaning device, including but not limited to floor scrubbers, vacuum cleaners, etc., for cleaning dirt such as dust, debris and hair on the ground. It achieves the cleaning function by driving a roller brush to rotate with airflow.

[0060] Please refer to Figure 1 , Figure 2 and Figure 3 As shown, the floor brush assembly 10 includes a floor brush body 100, a roller brush 200, and a walking mechanism mounted on the floor brush body 100. The walking mechanism consists of a wheel axle located at the rear of the floor brush body 100, two large-sized first walking wheels 112 coaxially connected to both ends of the wheel axle, and a small-sized second walking wheel 113 located at the front of the floor brush. The bottom of the floor brush body 100 has a clearance notch to avoid the first walking wheels 112 and the second walking wheels 113, so that parts of the first walking wheels 112 and the second walking wheels 113 can be exposed outside the bottom of the floor brush body 100 to roll into contact with the ground and achieve the purpose of walking.

[0061] The roller brush 200 is rotatably mounted inside the floor brush body 100, and the bottom of the floor brush body 100 has an opening to avoid the roller brush 200, allowing the bristles of the roller brush 200 to be exposed on the outside of the bottom of the floor brush body 100. This allows the bristles of the roller brush 200 to contact the ground, thereby picking up debris, hair, and other garbage on the ground. The floor brush body 100 also has a suction pipe 120, with a dust suction port on the side of the suction pipe 120 facing the ground. Along the axial direction of the roller brush 200, the dust suction port is located near the middle area of ​​the roller brush 200. Both sides of the roller brush 200 have air inlet channels connected to the dust suction port. The other end of the suction pipe 120 is connected to the dust suction chamber inside the brush body 100. A negative pressure device is provided on the flow path of the suction pipe 120 and the dust suction chamber to generate negative pressure, so that dust particles, debris, hair and other objects on the ground can be sucked in through the dust suction port along the air inlet channels at both ends of the roller brush 200. At the same time, during the rotation of the roller brush 200, it can peel off the garbage on the ground and roll up the debris, hair and other objects on the ground so that the suction airflow can suck them into the dust collection chamber through the dust suction port, thereby achieving the purpose of dust suction.

[0062] like Figure 1 and 2 As shown, the floor brush body 100 includes a floor brush lower housing 110, a dust collection chamber upper cover 130, a floor brush upper cover 140, a drive motor 300, and a transmission mechanism 500, etc. The floor brush lower housing 111 includes a floor brush lower housing 111 and a walking mechanism. A roller brush 200 is mounted on the floor brush lower housing 111. The drive motor 300 is connected to the roller brush 200 via the transmission mechanism 500 to drive the roller brush 200 to rotate around its own axis. The floor brush lower housing 111 has a dust collection groove, and the dust collection chamber upper cover 130 is mounted on the floor brush lower housing 111. The brush is mounted on the lower shell 111 so that the dust collection chamber cover 130 is sealed to the wall of the dust collection groove to form a dust collection chamber. The suction pipe 120 is connected to the dust collection chamber and fixed to the lower shell 111. In addition, other parts inside the brush body 100 are installed. After all the parts inside the brush body 100 are installed, the brush cover 140 is installed on the lower shell 111 and detachably connected to it so as to facilitate the replacement, repair and maintenance of other parts inside the brush body 100.

[0063] However, due to the relative rotation between the roller brush 200 and the floor brush body 100, hair, fibers and other easily tangled objects sucked in at both ends will get tangled at both ends of the roller brush 200, which will increase the rotational resistance of the roller brush 200 and cause the motor load to rise sharply. This will not only affect the cleaning efficiency, but may also cause the motor to overload and stop or be damaged, reducing the reliability and service life of the product.

[0064] Therefore, this application improves the floor brush assembly 10 so that hair and other entangled objects can be blocked during the cleaning process. This prevents hair and other entangled objects from getting caught and tangled at both ends of the roller brush 200 when they move with the airflow, thereby reducing the risk of hair and other entangled objects getting tangled at both ends of the roller brush 200, improving the anti-tangling performance of the equipment, effectively preventing the roller brush 200 from increasing its rotational resistance, improving the cleaning effect and efficiency of the roller brush 200, and extending the reliability and service life of the product.

[0065] The improvements 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.

[0066] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the floor brush body 100 has a mounting cavity with an open bottom. The roller brush 200 is rotatably mounted in the mounting cavity and connected to the drive motor 300. The floor brush assembly 10 also includes two blocking members 400, which are respectively disposed at the two axial ends of the roller brush 200. Each blocking member 400 is fixed on the floor brush body 100 and located at the bottom of the corresponding end of the roller brush 200, and cooperates with the outer peripheral wall of the corresponding end of the roller brush 200. Each blocking member 400 is configured to block the assembly gap between the end face of the corresponding end of the roller brush 200 and the adjacent side wall of the mounting cavity.

[0067] In the floor brush assembly 10 provided in this application embodiment, by providing shielding members 400 at both axial ends of the roller brush 200, the shielding members 400 are fixedly connected to the floor brush body 100 and located near the bottom of the corresponding rolling end, and cooperate with the outer peripheral wall of the corresponding end of the roller brush 200, so that the side walls of the mounting cavity for mounting the roller brush 200 at both ends are blocked and the end faces of the corresponding ends of the roller brush 200. In this way, when the equipment is cleaning, hair and other entangled objects are blocked by the shielding members 400, so that when the hair and other entangled objects move with the airflow direction, they are not easy to be rolled into and wrapped around the two ends of the roller brush 200, thereby reducing the risk of hair and other entangled objects easily getting wrapped around the two ends of the roller brush 200, improving the anti-winding performance of the equipment, effectively preventing the increase of the rotational resistance of the roller brush 200, improving the cleaning effect and efficiency of the roller brush 200, and extending the reliability and service life of the product.

[0068] For example, the shield 400 can be a plate-shaped structure, which facilitates the installation of the shield 400. In addition, the flat surface of the plate-shaped shield 400 can effectively prevent hair and debris from entering the floor brush assembly 10. It also has a simple structure, is easy to process, and has a low cost.

[0069] Please refer to Figure 5 and Figure 6 As shown, along the radial direction of the roller brush 200, the distance between each blocking member 400 and the central axis of the roller brush 200 is less than the distance between the outer peripheral surface of the roller brush 200 and the central axis of the roller brush 200. In other words, the fit between the blocking member 400 and the bristles of the roller brush 200 is an interference fit. This can further prevent hair and other entangled objects from getting caught between the roller brush 200 and the blocking member 400, thus further improving the anti-tangling performance.

[0070] For example, such as Figure 5 and Figure 6As shown, the interference dimension between the shielding members 400 at both ends of the roller brush 200 and the bristles of the roller brush 200 in the radial direction is, for example, expressed by the letter d. That is, along the radial direction of the roller brush 200, the difference between the distance between the outer peripheral surface of the roller brush 200 and the central axis of the roller brush 200 and the distance between each shielding member 400 and the central axis of the roller brush 200 is d, and d is 1~3mm, for example, d is 1mm, 1.5mm, 2mm, 2.5mm, 3mm, etc. In this way, it can effectively prevent hair and other entangled objects from getting caught between the roller brush 200 and the shielding member 400. At the same time, it can avoid the shielding member 400 from increasing the resistance to the rotation of the roller brush 200 and ensure the smooth rotation of the roller brush 200.

[0071] Additionally, please continue to refer to Figure 5 and Figure 6 As shown, along the radial direction of the roller brush 200, the projections of each blocking member 400 overlap with the projections of the corresponding ends of the roller brush 200. The dimension of the overlapping area in the axial direction of the roller brush 200 is c, where c is 1~3mm, for example, d is 1mm, 1.5mm, 2mm, 2.5mm, 3mm, etc. In this way, the axial fit between the blocking member 400 and the roller brush 200 is an interference fit, forming an effective barrier between the end of the roller brush 200 and the blocking member 400. This can effectively prevent hair and other entangled objects from being rolled into the space between the roller brush 200 and the blocking member 400. In addition, the interference fit dimension is set between 1~3mm, which can avoid the blocking member 400 increasing the resistance to the rotation of the roller brush 200 and ensure the smooth rotation of the roller brush 200.

[0072] Please refer to Figure 7 , Figure 8 and Figure 9 As shown, the floor brush assembly 10 includes a transmission mechanism 500 connected to the drive motor 300. The transmission mechanism 500 includes a transmission bracket 510, a first bearing 530, and a transmission component 520. One end of the roller brush 200 along the axial direction has a first roller brush connector 210. The drive motor 300 and the transmission bracket 510 are arranged adjacent to the first roller brush connector 210, and the power output end of the drive motor 300 is connected to the input end of the transmission component 520. The power output end of the transmission component 520 is connected to the first roller brush connector 210. The transmission bracket 510 is fixed on the floor brush body 100 and has a first accommodating space 511. The first roller brush connector 210 is coaxially connected to the first bearing 530 and is accommodated in the first accommodating space 511. In this way, by embedding the first roller brush connector 210 in the first accommodating space 511, hair and other entangled objects can be prevented from getting tangled in the first roller brush connector 210, thereby further improving the anti-tangling performance of the equipment.

[0073] For example, such as Figure 9As shown, the first accommodating space 511 on the transmission bracket 510 is a recessed area with an opening facing the first roller brush connector 210. In this way, the first roller brush connector 210 is embedded in the recessed area to prevent hair and other entangled objects from getting tangled in the first roller brush connector 210.

[0074] like Figure 8 As shown, the transmission component 520 includes a transmission belt 522 and a gear 521. The inner peripheral wall of the transmission belt 522 may be provided with meshing teeth. The drive motor 300 has a drive shaft with gear teeth that match the meshing teeth on the transmission belt 522. The outer peripheral wall of the gear 521 also has gear teeth that match the meshing teeth on the transmission belt 522. Thus, the transmission belt 522 meshes with the drive shaft and the gear 521 respectively. The gear 521 is coaxially connected to the first roller brush connector 210. The first roller brush connector 210 is mounted on the transmission bracket 510 through the first bearing 530. When the drive motor 300 is working, it can drive the transmission belt 522 to move through the drive shaft. The transmission belt 522 drives the gear 521 to rotate. The gear 521 drives the first roller brush connector 210 to rotate around its own axis, thereby driving the entire roller brush 200 to rotate around its own axis.

[0075] Among them, such as Figure 10 and Figure 11 As shown, the roller brush 200 includes a roller brush bracket 230 and a cleaning part 240 mounted on the outer peripheral wall of the roller brush bracket 230. The cleaning part 240 includes, but is not limited to, a cleaning cloth, multiple cleaning silicone strips, cleaning bristle strips, etc., as long as it can clean the floor. One end of the roller brush bracket 230 has a first roller brush connector 210 and the other end has a second roller brush connector 220. In this way, the drive motor 300 can drive the first roller brush connector 210 to rotate around its own axis through the transmission component 520, thereby driving the roller brush bracket 230 to rotate around its own axis, so that the cleaning part 240 can clean the floor as it rotates with the roller brush bracket 230.

[0076] Please continue to refer to Figure 10 and Figure 11As shown, since the roller brush bracket 230 needs to rotate relative to the floor brush body 100 via the second roller brush connector 220, the floor brush assembly 10 also includes a bearing mechanism 600 to improve the smoothness of rotation and reduce wear. The bearing mechanism 600 includes a bearing bracket 610 and a second bearing 620. The bearing bracket 610 is fixed to the floor brush body 100 adjacent to the second roller brush connector 220, for example, by a screw 650 threaded connection to the floor brush body 100. The bearing bracket 610 has a second accommodating space 611. The second roller brush connector 220... The second bearing 620 is coaxially connected to the second bearing bracket 610 via a connecting shaft 640 and housed within the second accommodating space 611. That is, the second bearing 620 is mounted on the bearing bracket 610, and the second roller brush connector 220 is coaxially connected to the second bearing 620. In this way, the second roller brush connector 220 can rotate relative to the bearing bracket 610 around its own axis. By embedding the second roller brush connector 220 within the second accommodating space 611, hair and other entangled objects can be prevented from getting tangled around the second roller brush connector 220, thereby further improving the anti-tangling performance of the equipment.

[0077] In addition, such as Figure 10 and Figure 11 As shown, the floor brush assembly 10 also includes a handle 630, which is mounted on the bearing bracket 610. In this way, when the bearing bracket 610 is disassembled from the floor brush body 100, the bearing bracket 610 can be taken out through the handle 630 for user operation.

[0078] In addition, such as Figure 11 As shown, the shield 400, which is located on the same side of the roller brush 200 as the handle 630, is connected to the handle 630. In this way, while enabling the easy disassembly of the bearing bracket 610, the lifting mechanism also provides a support base for the shield 400, which is located on the same side of the roller brush 200. This eliminates the need for an additional support structure for the shield 400, simplifying the structure of the equipment and reducing manufacturing costs.

[0079] For example, the handle 630 and the cover 400 connected to the handle 630 are integrated into one structure, which reduces the installation process and lowers costs.
