Description

Technical Field

[0001] This utility model relates to the technical field of cleaning equipment, and more specifically, to roller brush assemblies and automatic cleaning equipment. Background Technology

[0002] As living standards continue to improve, more and more families are choosing to use automatic cleaning equipment (such as robotic vacuum cleaners and robot vacuum and mop combos) to improve household cleaning efficiency. These devices typically rely on a roller brush assembly to clean the floor, using the rotation of the brush to sweep dust, hair, debris, and other impurities into the device's dust collection unit.

[0003] However, existing roller brush assemblies have shortcomings in practical applications: during the cleaning process, long fibrous impurities (such as hair, pet hair, and lint) are easily entangled. These impurities will tightly wrap around the surface of the roller brush or get rolled into the gaps at the end of the roller brush shaft, which not only hinders the normal rotation of the roller brush, but also blocks the suction channel, resulting in a sharp drop in cleaning efficiency or even the equipment stopping.

[0004] Based on this, the present invention provides a roller brush assembly and an automatic cleaning device. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a roller brush assembly and an automatic cleaning device.

[0006] The roller brush assembly and automatic cleaning equipment provided by this utility model adopt the following technical solution:

[0007] A roller brush assembly includes a roller brush body, a shearing mechanism, and a driving mechanism. The shearing mechanism is disposed on the outer side of the roller brush body, and the driving mechanism is disposed within the roller brush body. The roller brush body has a receiving cavity inside, and a shearing opening is formed on the outer side of the roller brush body. The shearing mechanism includes a fixed shear blade, which is fixedly disposed within the shearing opening; and a movable shear blade, which is slidably disposed within the shearing opening via a connecting strip, and the fixed shear blade is in contact with the movable shear blade. The driving mechanism is used to drive the connecting strip to reciprocate within the roller brush body.

[0008] Preferably, the driving mechanism includes a rotating shaft rotatably disposed inside the brush body, a reciprocating wheel is disposed in the middle of the rotating shaft, a pair of retaining pads are disposed at the bottom of the connecting strip, the reciprocating wheel is located between the two retaining pads, and the reciprocating wheel is configured to drive the two retaining pads to reciprocate along the axial direction of the rotating shaft when rotating.

[0009] Preferably, the roller brush body is provided with multiple track plates, and the side of the movable shear blade is slidably connected to the track plates.

[0010] Preferably, the drive mechanism further includes a gear sleeve fixedly disposed inside the roller brush body, the side end of the rotating shaft is arranged inside the gear sleeve, a planetary gear set is disposed inside the gear sleeve, and the outer teeth of the planetary gear set mesh with the inner teeth of the gear sleeve, and the side end of the rotating shaft is connected to the planetary gear set.

[0011] Preferably, a pair of cleaning strips are provided on the outer surface of the roller brush body.

[0012] An automatic cleaning device includes a device body and the aforementioned roller brush assembly, wherein the roller brush assembly is disposed within the device body.

[0013] In summary, this utility model has the following beneficial technical effects:

[0014] The drive mechanism drives the connecting strip to reciprocate within the roller brush body, causing the movable scissor blades to reciprocate within the cutting opening. The movable and fixed scissor blades then work together to complete the cutting action. Simultaneously, the drive mechanism also drives the roller brush body, thereby collecting impurities and cutting them off through the cutting mechanism. This structural design allows for the cutting of impurities, facilitating their collection and preventing clogging of the cleaning equipment. Furthermore, hair-like impurities can be cut off by the cutting mechanism, preventing them from tangling on the outer surface of the roller brush body (an active "anti-tangling" capability).

[0026] It should be noted that the accompanying drawings are schematic and not to scale.

Furthermore, the same reference numerals are used for the same structures, elements, or fittings appearing in more than two drawings to indicate similar features.

[0027] Example 1

[0028] This utility model discloses a roller brush assembly. (Refer to...) Figures 1 to 7 The roller brush assembly includes a roller brush body 1, a shearing mechanism 2, and a driving mechanism 3. The shearing mechanism 2 is disposed on the outer side of the roller brush body 1, and the driving mechanism 3 is disposed inside the roller brush body 1. The roller brush body 1 has a receiving cavity inside, and a shearing opening 4 is provided on the outer side of the roller brush body 1.

[0029] The shearing mechanism 2 includes a fixed shear blade 200 and a movable shear blade 201; the fixed shear blade 200 is fixedly disposed in the shearing opening 4; the movable shear blade 201 is slidably disposed in the shearing opening 4 through the connecting strip 202, and the fixed shear blade 200 is in contact with the movable shear blade 201; the driving mechanism 3 is used to drive the connecting strip 202 to reciprocate within the roller brush body 1.

[0030] Specifically, the driving mechanism 3 drives the connecting bar 202 to reciprocate within the roller brush body 1, thereby causing the movable scissor blade 201 to reciprocate within the cutting opening 4. The movable scissor blade 201 cooperates with the fixed scissor blade 200 to complete the cutting action. At the same time, the driving mechanism 3 also drives the roller brush body 1, thereby winding up impurities and cutting them through the cutting mechanism 2. Through this structural design, impurities can be cut off, facilitating their collection and preventing them from clogging the cleaning equipment. Moreover, hair-like impurities can be cut off by the cutting mechanism 2, preventing them from tangling on the outer surface of the roller brush body 1 (active "anti-tangling" capability).

[0031] like Figures 3 to 5 As shown, the drive mechanism 3 includes a rotating shaft 300, which is rotatably disposed inside the roller brush body 1. A reciprocating wheel 301 is disposed in the middle of the rotating shaft 300, and a pair of retaining pads 302 are disposed at the bottom of the connecting strip 202. The reciprocating wheel 301 is located between the two retaining pads 302. The reciprocating wheel 301 is configured to drive the two retaining pads 302 to reciprocate along the axial direction of the rotating shaft 300 when rotating. The rotating shaft 300 is connected to an external motor, and the rotating shaft 300 is driven to rotate by the motor and other drive components.

[0032] Specifically, the rotation of the shaft 300 causes the reciprocating wheel 301 to rotate, thereby causing the two pads 302 to move back and forth within the brush body 1, which in turn drives the movable scissor blade 201 on the connecting strip 202 to move back and forth within the cutting opening 4.

[0033] like Figure 7 As shown, multiple track plates 303 are provided inside the roller brush body 1. The side of the movable scissor blade 201 is slidably connected to the track plate 303. By setting the track plate 303, the stability of the movable scissor blade 201 during movement can be increased.

[0034] like Figure 4 As shown, the drive mechanism 3 also includes a gear sleeve 304 fixedly disposed inside the roller brush body 1. The side end of the rotating shaft 300 is arranged inside the gear sleeve 304. A planetary gear set 305 is disposed inside the gear sleeve 304, and the outer teeth of the planetary gear set 305 mesh with the inner teeth of the gear sleeve 304. The side end of the rotating shaft 300 is connected to the planetary gear set 305.

[0035] Specifically, the rotation of the rotating shaft 300 causes the planetary gear set 305 to rotate, which in turn causes the gear sleeve 304 to rotate. The gear sleeve 304 is connected to the roller brush body 1, thereby driving the roller brush body 1 to rotate. Through this design, the roller brush body 1 can be rotated. Furthermore, through the cooperation between the planetary gear set 305 and the gear sleeve 304, the roller brush body 1 can rotate at a slower speed, making it easier for the suction port on the cleaning equipment to pick up the chopped impurities.

[0036] Specifically, a positioning rod 6 is provided inside the roller brush body 1, and the side end of the toothed sleeve 304 is rotatably connected to the positioning rod 6.

[0037] like Figure 1 and Figure 2 As shown, a pair of cleaning strips 5 are provided on the outer side of the roller brush body 1, and external impurities are cleaned by the cleaning strips 5.

[0038] Example 2

[0039] like Figure 8 As shown, an automatic cleaning device includes a device body and the aforementioned roller brush assembly, the roller brush assembly being disposed within the device body.

[0040] Specifically, in the above embodiments, the roller brush assembly is assembled at the bottom of the automatic cleaning device, and the roller brush assembly is driven to rotate by the drive component inside the cleaning device, thereby completing the cleaning of external impurities.
