Description

A brush roller and a floor scrubber equipped with the brush roller

Technical Field

The present invention relates to the technical field of cleaning equipment, and in particular to a brush roller and a floor scrubber equipped with the brush roller.

Background Art

The brush roller of the floor scrubber adopting water-dust circulation technology is installed in the cleaning head to sweep the garbage rolled up by the sponge roller into the garbage box. The brush roller does not need to sweep the ground, but only needs to sweep the surface of the sponge roller after being flushed with clean water in the closed cleaning space in the lower rear section, and sweep the garbage blocked by the filter device of the closed cleaning space outside the water flow channel into the garbage box.

Chinese patent document CN112674642A discloses a roller brush assembly, including a first roller brush, a reciprocating mechanism and a cutting piece; the cutting piece is connected to the reciprocating mechanism so that the cutting piece reciprocates along the axial direction parallel to the first roller brush under the drive of the reciprocating mechanism, and the cutting piece applies a cutting force to the object wrapped around the first roller brush, and can cut the attachments wrapped around the roller brush. Figures 13-15 of the specification and paragraphs 112-114 of the specification disclose that the roller brush assembly can also include a second roller brush, as shown in Figure 13, the second roller brush is arranged along the axial direction parallel to the first roller brush, and there is a movable gap between the second roller brush and the first roller brush, or the second roller brush and the first roller brush can also fit each other. The second roller brush does not have a cutting piece, and the second roller brush can be equipped with bristles or a circle of soft material, and the second roller brush cleans the area to be cleaned. When there are entangled objects (such as hair, woolen thread, etc.) on the second roller brush, the first roller brush can clean the entangled objects on the second roller brush, so that the entangled objects on the second roller brush are transferred to the first roller brush, and the cutting piece arranged in the first roller brush can cut the entangled objects transferred to the first roller brush. One end of the second roller brush is connected to the second driving device, so that the second driving device can drive the second roller brush to rotate, and the other end of the second roller brush is provided with a power output end, which is connected to the second transmission mechanism, and at the same time, the second transmission mechanism is connected to the second transfer rotating member, and the second transfer rotating member is fixedly connected to the first roller brush. When the second roller brush rotates, the second roller brush can drive the power output end to rotate, and then the power output end can drive the second transmission mechanism to move. When the second transmission mechanism moves, it can drive the second transfer rotating member to move, and then the first roller brush starts to rotate. Finally, the cutting piece arranged in the first roller brush can make reciprocating motion in a direction parallel to the axial direction of the first roller brush, so as to achieve the effect of cutting the winding transferred to the first roller brush. The first roller brush can also be driven by the second roller brush instead of an independent driving device outside or inside the first roller brush, and the independent driving device drives the first roller brush to rotate, so as to make the cutting piece arranged in the first roller brush make reciprocating motion in a direction parallel to the axial direction of the first roller brush, so as to achieve the effect of cutting the winding transferred to the first roller brush.

The roller brush assembly in the existing air-dust circulation floor cleaner is fixed at one end in a relatively complicated manner, and the other end is driven by a separate drive motor through a gear set or a synchronous belt. When the roller brush needs to be maintained separately, there are many steps for disassembling and assembling the roller brush, which results in a poor user experience.

At present, the roller brush assembly in the water-dust circulation floor cleaner is fixed at one end in a relatively complicated way, and the other end is driven by a separate drive motor through a gear set or directly driven by a motor's built-in reduction device. When the roller brush needs to be maintained separately, there are many steps to disassemble and assemble the roller brush, which is not a good user experience. Moreover, the repeated disassembly and assembly of the fastening screws on the non-driving end will cause inconsistent resistance on one end of the brush roller. Therefore, it is necessary to design a solution that is easy to disassemble and assemble and allows the roller brush to operate stably and reliably.

As shown in Figures 1 to 10, the present invention provides a schematic structural diagram of an embodiment of a brush roller.

The brush roller comprises a brush roller body 1 and a fixing mechanism 2 for mounting the brush roller body, wherein the fixing mechanism 2 is respectively provided with a first matching portion 21 matched and fixed with the first end 11A of the brush roller body and a second matching portion 22 matched and fixed with the second end 12 of the brush roller body, wherein the first end 11A of the brush roller body is provided with a bearing 111, wherein the bearing 111 is fixed with a brush handle 11, wherein the brush handle 110 is provided at the first end 11A. The first matching portion 21 is provided with a fixed positioning structure for fixing the brush handle 110, wherein the second end 12 of the brush roller body is provided with a transmission gear 33, and a rotating shaft 35 extending coaxially with the transmission gear 33, wherein the end surface of the rotating shaft 35 is provided with a cavity (not shown in the drawings) for receiving a protrusion provided at the second end 12 of the brush roller body, wherein the wall of the cavity is a non-cylindrical surface.

Specifically, the fixing mechanism 1 is provided with a transmission gear set 3 and a driving mechanism (not shown in the drawings) for driving the transmission gear set 3 to work, the driving mechanism including a motor, and an electrode spring 23 connected to the driving mechanism is provided on the fixing mechanism 2. The transmission gear set 3 is a reduction gear set, which is meshed with the transmission gear 33 to achieve the rotation of the brush roller. The reduction gear set can change the output speed of the motor and amplify the torque.

The brush handle 11 includes a handle body 110 provided with a fixing cavity for fixing a bearing 111, two fixing plates 112 are provided at the plug-in end of the handle body 110 in the same direction of plug-in, the tail of the fixing plate 112 is connected to the handle body 110, a gap 113 is formed between the fixing plate 112 and the handle body 110, and an elastic clamping groove 114 is provided on the side of the fixing plate 112 close to the gap 113. The elastic clamping groove 114 is close to the end of the fixing plate 112. The brush handle 11 is provided with a notch 115 at the plug-in end, and the bottom of the notch 115 is an arc surface 116. Since the bottom of the notch 115 is an arc surface structure, it can form a larger contact surface with the fixed clamping structure after assembly, thereby improving the reliability and stability of the first end fixation.

The first matching part 21 is provided with a fixed clamping structure, and the fixed clamping structure 21 includes a fixed groove 212 respectively matched with the fixed plate 112, and a clamping strip 213 is respectively provided in the fixed groove 212. The clamping strip in the fixed groove 213 and the elastic clamping slot 114 on the fixed plate 112 can better improve the reliability and stability of the brush roller installation. According to needs, the clamping strip 213 forms an angle a with the horizontal direction. The angle a is 30-60 degrees, and the clamping strip 213 matches the elastic clamping slot 114, that is, the clamping strip 213 forms an angle a with the horizontal direction, and the angle is consistent with the angle formed by the elastic clamping slot 114 and the horizontal direction. Since the inclined clamping strip 213 cooperates with the inclined elastic clamping slot 114, when the matching gap becomes larger due to wear after use, the brush roller is always pressed to one end by cooperating with the inclined clamping strip and the inclined elastic clamping slot 114, which can avoid the noise after a long time of use and improve the service life. Furthermore, since the clamping strip 213 and the elastic clamping slot 114 are matched with each other at an angle, it is more labor-saving during installation or removal.

The fixed clamping structure is provided with a protrusion 210 between the two fixing plates 112, and the end surface of the protrusion 210 is provided with an arc surface 116 that matches the notch 115, which can better improve the fixing effect after installation and avoid left and right movement in the vertical direction of installation. The width of the protrusion 210 is interference fit with the shape of the two fixing plates 112, and the clamping force formed after the two fixing plates 112 and the protrusion 210 are installed can better improve the fixing effect after installation. The brush handle 11 is usually injection molded by plastic material, and the fixing plate 112 has a certain elastic variable performance.

By changing the matching mode of the non-driving end of the brush roller and the corresponding bracket of the brush roller assembly housing, it is not only easy to remove with one hand, but also able to withstand a certain radial force in the working state, so as not to be easily loosened after a little impact. A U-shaped clamping strip with two clamping strips is set at one end of the brush roller assembly support. After the bearing is clamped with a retaining spring at one end of the brush roller, a horse brush handle with interference fit on the outer ring of the bearing is used. The brush handle is U-shaped and has two elastic bayonet holes. The U-shaped clamping strip and the U-shaped brush handle are mutually embraced for clamping, which not only ensures the clamping force, but also improves the convenience of removing the brush roller. The output end of the built-in thin motor drives the driving gear to rotate, and then meshes with the planetary gear. The planetary gear further meshes with the brush roller sleeve gear. The brush roller assembly only occupies a small thickness dimension in the axial direction, and more effective brushing area is left to the brush roller itself to the greatest extent, which is more conducive to brushing the dirty garbage on the sponge roller. The other end of the brush roller assembly is inserted into a correspondingly shaped hole concave at one end of the brush roller sleeve gear through a protruding square (or arbitrary polygonal) end, and no other tools are required for additional fastening, so the brush roller is easy to disassemble.

As required, the two ends of the brush roller body are provided with isolation parts 4, which can prevent the slender object from being turned into the two ends during operation, increasing resistance or even getting stuck. The isolation part 4 is annular and coaxial with the brush roller shaft, and the isolation part 4 is set as an inclined surface 41 from the nearest end of the brush roller to the inside. The inclined surface 41 can make the slender object move to the inside of the brush roller, thereby avoiding the increase of resistance between the end and the bearing.

As shown in FIG. 1 to FIG. 10 , the present invention also provides an embodiment of a floor scrubber equipped with a brush roller.

The floor scrubber equipped with a brush roller includes a brush roller, which includes a brush roller body 1 and a fixing mechanism 2 for installing the brush roller body, the fixing mechanism 2 is respectively provided with a first matching portion 21 matched and fixed with the first end 11A of the brush roller body and a second matching portion 22 matched and fixed with the second end 12 of the brush roller body, the first end 11A of the brush roller body is provided with a bearing 111, the bearing 111 is fixed to the brush handle 11, the first matching portion 21 is provided with a fixed positioning structure for fixing the brush handle 11, the second end 12 of the brush roller body is provided with a transmission gear 33, and a rotating shaft 35 extending coaxially with the transmission gear 33, the end face of the rotating shaft 35 is provided with a cavity (not shown in the drawings) for accommodating the protrusion set at the second end 12 of the brush roller body, and the cavity wall is a non-cylindrical surface.

Specifically, the fixing mechanism 1 is provided with a transmission gear set 3 and a driving mechanism (not shown in the drawings) for driving the transmission gear set 3 to work, the driving mechanism including a motor, and an electrode spring 23 connected to the driving mechanism is provided on the fixing mechanism 2. The transmission gear set 3 is a reduction gear set, which is meshed with the transmission gear 33 to achieve the rotation of the brush roller. The reduction gear set can change the output speed of the motor and amplify the torque.

The brush handle 11 includes a handle body 110 provided with a fixing cavity for fixing a bearing 111, two fixing plates 112 are provided at the plug-in end of the handle body 110 in the same direction of plug-in, the tail of the fixing plate 112 is connected to the handle body 110, a gap 113 is formed between the fixing plate 112 and the handle body 110, and an elastic clamping groove 114 is provided on the side of the fixing plate 112 close to the gap 113. The elastic clamping groove 114 is close to the end of the fixing plate 112. The brush handle 11 is provided with a notch 115 at the plug-in end, and the bottom of the notch 115 is an arc surface 116. Since the bottom of the notch 115 is an arc surface structure, it can form a larger contact surface with the fixed clamping structure after assembly, thereby improving the reliability and stability of the first end fixation.

The fixed clamping structure includes a fixed groove 212 that matches the fixed plate 112, and a clamping strip 213 is provided in the fixed groove 212. The clamping strip in the fixed groove 213 and the elastic clamping slot 114 on the fixed plate 112 can better improve the reliability and stability of the brush roller installation. According to needs, the clamping strip 213 forms an angle a with the horizontal direction. The angle a is 30-60 degrees. The clamping strip 213 matches the elastic clamping slot 114, that is, the clamping strip 213 forms an angle a with the horizontal direction, and the angle is consistent with the angle formed by the elastic clamping slot 114 and the horizontal direction. Since the inclined clamping strip 213 cooperates with the inclined elastic clamping slot 114, when the matching gap becomes larger due to wear after use, the brush roller is always pressed to one end by cooperating with the inclined clamping strip and the inclined elastic clamping slot 114, which can avoid the noise after a long time of use and improve the service life. Furthermore, since the clamping strip 213 and the elastic clamping slot 114 are matched with each other at an angle, it is more labor-saving during installation or removal.

The fixed clamping structure is provided with a protrusion 210 between the two fixing plates 112, and the end surface of the protrusion 210 is provided with an arc surface 116 that matches the notch 115, which can better improve the fixing effect after installation. The width of the protrusion 210 is interference-fitted with the shape of the two fixing plates 112, and the clamping force formed after the two fixing plates 112 and the protrusion 210 are installed can better improve the fixing effect after installation. The brush handle 11 is usually injection-molded by plastic material, and the fixing plate 112 has a certain elastic variable performance.

By changing the matching mode of the non-driving end of the brush roller and the corresponding bracket of the brush roller assembly housing, it is not only easy to remove with one hand, but also able to withstand a certain radial force in the working state, so as not to be easily loosened after a little impact. A U-shaped clamping strip with two clamping strips is set at one end of the brush roller assembly support. After the bearing is clamped with a retaining spring at one end of the brush roller, a horse brush handle with interference fit on the outer ring of the bearing is used. The brush handle is U-shaped and has two elastic bayonet holes. The U-shaped clamping strip and the U-shaped brush handle are mutually embraced for clamping, which not only ensures the clamping force, but also improves the convenience of removing the brush roller. The output end of the built-in thin motor drives the driving gear to rotate, and then meshes with the planetary gear. The planetary gear further meshes with the brush roller sleeve gear. The brush roller assembly only occupies a small thickness dimension in the axial direction, and more effective brushing area is left to the brush roller itself to the greatest extent, which is more conducive to brushing the dirty garbage on the sponge roller. The other end of the brush roller assembly is inserted into a hole of a corresponding shape concave at one end of the brush roller sleeve gear through a protruding square (or arbitrary polygonal) end, and no other tools are required for additional fastening, so the brush roller is easy to disassemble.

As required, the two ends of the brush roller body are provided with isolation parts 4, which can prevent the slender object from being turned into the two ends during operation, increasing resistance or even getting stuck. The isolation part 4 is annular and coaxial with the brush roller shaft, and the isolation part 4 is set as an inclined surface 41 from the nearest end of the brush roller to the inside. The inclined surface 41 can make the slender object move to the inside of the brush roller, thereby avoiding the increase of resistance between the end and the bearing.
