Description

A roller brush hair entanglement cleaning structure Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a cleaning structure for cleaning hair entanglement in a roller brush. Background Technology

[0002] Vacuum cleaners are commonly used for cleaning floors. Their working principle involves an electric motor driving blades to rotate at high speed, creating negative air pressure within a sealed housing. This negative pressure is then used to suck up dust and debris through a floor brush connected to the suction hose. The roller brush is one of the main components of the floor brush assembly. The brush motor drives the roller brush to rotate, bringing dust and debris from the floor to the suction port, where it is then sucked into the vacuum cleaner, thus achieving the effect of cleaning and dust removal. During operation, a large amount of hair can become entangled on the roller brush, affecting its cleaning effectiveness.

[0003] To address the aforementioned technical problems, Chinese Patent Publication No. CN220572112U provides a floor brush comb. The comb is positioned close to a roller brush, and at least a portion of the roller brush has a soft scraping area. The comb includes a comb body comprising several tooth tips arranged along the axial direction of the roller brush. When the roller brush rotates, the tooth tips can insert into the soft scraping area of ​​the roller brush to comb through the hair tangled on it. While this floor brush comb can clean hair tangled on the roller brush, the tooth tips can interfere with the operation of the roller brush, thus affecting its normal function.

[0004] Therefore, existing technologies still need to be improved and developed. Technical solutions

[0005] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a roller brush hair entanglement cleaning structure. By opening and closing the drive mechanism connected to the scraper, the scraper can be switched between a second position that extends into the roller brush and a first position that does not contact the roller brush.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This utility model provides a cleaning structure for cleaning hair entanglement in a roller brush, including a scraper rotatably disposed in a housing. The scraper is arranged parallel to the length direction of the roller brush. The scraper is driven by a drive mechanism to swing to a second position extending into the roller brush. A first reset mechanism is connected to the scraper, which is used to reset the scraper from the second position to a first position where it does not contact the roller brush.

[0008] With the above-mentioned structural design, when it is necessary to clean the hair wrapped around the roller brush, the drive mechanism can be turned on to swing the scraper to the second position that extends into the roller brush. After the drive mechanism is turned off, the scraper is reset to the first position that does not contact the roller brush under the action of the first reset mechanism, so as not to interfere with the roller brush in normal operation.

[0009] According to the above scheme, the driving mechanism includes a pedal connecting rod and a transmission connecting rod respectively rotatably disposed in the housing; a pedal is provided on the first end of the pedal connecting rod, the second end of the pedal connecting rod abuts against the first end of the transmission connecting rod, and the second end of the transmission connecting rod abuts against the actuating block on the brush; the brush can be driven by the actuating block to swing to a second position that extends into the inside of the roller brush.

[0010] With the above structural design, when it is necessary to clean the hair wrapped around the roller brush, pressing down the pedal drives the pedal linkage and transmission linkage to rotate, causing the actuating block on the scraper to swing downwards. The scraper, driven by the actuating block, swings forward and upwards to the second position, extending into the roller brush. After cleaning is completed, releasing the pedal causes the scraper to return to the first position, which is not in contact with the roller brush, under the action of the first reset mechanism, thus preventing interference with the normally functioning roller brush. In other words, by pressing down or releasing the pedal, the scraper can be switched between the second position, which extends into the roller brush, and the first position, which is not in contact with the roller brush.

[0011] According to the above scheme, the upper end of the brush is provided with a first support shaft that passes laterally through it, and the first support shaft is fixed inside the housing. This structural arrangement allows the brush to swing around the first support shaft under the action of the actuating block.

[0012] According to the above scheme, the first reset mechanism is a torsion spring, which is disposed on the first support shaft. The torsion spring is used to apply a force to the scraper, causing the scraper to swing from the second position to the first position. With the above structural arrangement, after the scraper finishes its work, releasing the pedal eliminates the pressure applied to the actuating block, and the scraper can quickly reset to the first position where it does not contact the roller brush under the action of the torsion spring.

[0013] According to the above scheme, the lower end of the brush is provided with multiple comb teeth arranged along the length of the roller brush, and the comb teeth have a hook-shaped structure. By setting the comb teeth to a hook-shaped structure, it is convenient to clean the hair tangled on the roller brush.

[0014] According to the above scheme, it also includes a circuit board, on which a micro switch is provided. The micro switch is triggered by a trigger rod located at the bottom of the pedal. The micro switch is used to control the forward or reverse rotation of the roller brush motor connected to the roller brush.

[0015] When cleaning and dusting the ground, the roller brush motor rotates forward, driving the roller brush to rotate clockwise. When the pedal is pressed down, the trigger rod moves downward, triggering a micro switch, which controls the roller brush motor to rotate in reverse, thus driving the roller brush to rotate counterclockwise. When the pedal is released, under the action of the first reset mechanism, pedal linkage, and transmission linkage, the pedal swings upward, causing the trigger rod to disengage from the micro switch, and the roller brush motor switches to forward rotation. This structural design allows the forward or reverse rotation of the roller brush motor to be controlled by pressing or releasing the pedal.

[0016] According to the above scheme, a second reset mechanism is connected to the pedal linkage. By setting the second reset mechanism, the pedal linkage can be quickly reset after the pedal is released.

[0017] According to the above scheme, the second reset mechanism is a tension spring, which is located at the bottom of the second end of the pedal linkage.

[0018] When the pedal is pressed down, the second end of the pedal linkage swings upward, thereby stretching the tension spring; after the pedal is released, under the action of the first reset mechanism and the tension spring, the trigger rod quickly disengages from the micro switch.

[0019] It is understandable that, in order to enable the pedal linkage to return to its original position quickly, those skilled in the art may, depending on actual needs, use a compression spring located at the bottom of the first end of the pedal linkage or a torsion spring located on the pedal linkage as the second reset mechanism.

[0020] According to the above scheme, a second support shaft is provided through the middle of the transmission connecting rod, and the second support shaft is fixed inside the housing. This structural arrangement allows the transmission connecting rod to rotate around the second support shaft.

[0021] According to the above scheme, a limiting block is provided inside the housing, and the limiting block is located in front of the brush. By setting the limiting block, the forward and upward swing of the brush can be limited, preventing the brush from penetrating too deeply into the roller brush and affecting the rotation of the roller brush. Beneficial effects

[0022] The beneficial effects of this utility model are as follows:

[0023] This invention features a rotatable scraper housed within a housing. Driven by a mechanism, the scraper swings to a second position, extending into the interior of a roller brush. A first reset mechanism is connected to the scraper, resetting it from the second position to a first position where it does not contact the roller brush. When cleaning hair entangled in the roller brush is required, activating the drive mechanism swings the scraper to the second position. Activating the drive mechanism resets the scraper to the first position, preventing interference with the normally functioning roller brush. Attached Figure Description

[0031] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0032] As shown in Figures 1-6, this utility model provides a cleaning structure for cleaning hair entanglement in a roller brush, including a scraper 1 rotatably disposed in a housing (not shown in the figure). The scraper 1 is disposed along the length direction parallel to the roller brush 6. The scraper 1 is driven by a drive mechanism to swing to a second position extending into the roller brush 6. A first reset mechanism (not shown in the figure) is connected to the scraper 1. The first reset mechanism is used to reset the scraper 1 from the second position to a first position that does not contact the roller brush 6.

[0033] Furthermore, the driving mechanism includes a pedal linkage 3 and a transmission linkage 2 rotatably disposed within the housing; a pedal 4 is provided on the first end of the pedal linkage 3, the second end of the pedal linkage 3 abuts against the first end of the transmission linkage 2, and the second end of the transmission linkage 2 abuts against the actuating block 11 on the brush 1; the brush 1 can be driven by the actuating block 11 to swing to a second position extending into the inside of the roller brush 6.

[0034] With the above-described structure, when it is necessary to clean the hair wrapped around the roller brush 6, pressing down the pedal 4 drives the pedal linkage 3 and the transmission linkage 2 to rotate, thereby causing the actuating block 11 on the scraper 1 to swing downward. The scraper 1 is driven by the actuating block 11 to swing forward and upward to the second position that extends into the roller brush 6. After cleaning is completed, the pedal 4 is released, and the scraper 1 is reset to the first position that does not contact the roller brush 6 under the action of the first reset mechanism, so as not to interfere with the normally operating roller brush 6.

[0035] Furthermore, the upper end of the scraper 1 is provided with a first support shaft 12 that passes laterally through it, and the first support shaft 12 is fixed inside the housing. With the above structural arrangement, the scraper 1 can swing around the first support shaft 12 under the action of the actuating block 11.

[0036] Furthermore, the first reset mechanism is a torsion spring, which is mounted on the first support shaft 12. The torsion spring applies a force to the scraper 1, causing it to swing from the second position to the first position. With this structural arrangement, after the scraper 1 completes its work, releasing the pedal 4 eliminates the pressure applied to the actuating block 11, and the scraper 1 can quickly reset to the first position, where it does not contact the roller brush 6, under the action of the torsion spring.

[0037] Furthermore, the lower end of the brush 1 is provided with a plurality of comb teeth 13 arranged along the length of the roller brush 6, and the comb teeth 13 have a hook-shaped structure. By setting the comb teeth 13 to a hook-shaped structure, it is convenient to clean the hair entangled on the roller brush 6.

[0038] Furthermore, it also includes a circuit board 5, on which a micro switch 51 is provided. The micro switch 51 is triggered by a trigger rod 41 located at the bottom of the pedal 4. The micro switch 51 is used to control the forward or reverse rotation of the roller brush motor (not shown in the figure) connected to the roller brush 6.

[0039] When cleaning and dusting the ground, the roller brush motor rotates forward, driving the roller brush 6 to rotate clockwise. When the pedal 4 is pressed down, the trigger rod 41 swings downward, triggering the micro switch 51, thereby controlling the roller brush motor to drive the roller brush 6 to rotate counterclockwise. When the pedal 4 is released, under the action of the first reset mechanism, the pedal connecting rod 3, and the transmission connecting rod 2, the pedal 4 swings upward, thereby disengaging the trigger rod 41 from the micro switch 51, and the roller brush motor switches to forward rotation. Through the above structural design, the forward or reverse rotation of the roller brush motor can be controlled by pressing or releasing the pedal 4.

[0040] Furthermore, a second reset mechanism (not shown in the figure) is connected to the pedal linkage 3. By providing the second reset mechanism, the pedal linkage 3 can be quickly reset after the pedal 4 is released.

[0041] Furthermore, the second reset mechanism is a tension spring, which is located at the bottom of the second end of the pedal linkage 3. When the pedal 4 is pressed down, the second end of the pedal linkage 3 swings upward, thereby stretching the tension spring; after the pedal 4 is released, under the action of the first reset mechanism and the tension spring, the trigger rod 41 quickly disengages from the micro switch 51.

[0042] Furthermore, a second support shaft 21 is provided through the middle of the transmission link 2, and the second support shaft 21 is fixed inside the housing.

[0043] Furthermore, a limiting block (not shown in the figure) is provided inside the housing, and the limiting block is located in front of the scraper 1. By providing the limiting block, the forward and upward swing of the scraper 1 can be limited, preventing the scraper 1 from extending too deeply into the roller brush 6 and affecting the rotation of the roller brush 6.

[0044] As shown in Figure 5, in its natural state, the brush hair entanglement cleaning structure of this utility model has the scraper 1 in a first position where it is not in contact with the roller brush 6. As shown in Figure 6, when the brush hair entanglement cleaning structure is in operation, pressing down the pedal 4 drives the pedal 4, the trigger rod 41, and the first end of the pedal connecting rod 3 to swing downwards, while the second end of the pedal connecting rod 3 swings upwards. The second end of the pedal connecting rod 3 drives the first end of the transmission connecting rod 2 to swing upwards, while the second end of the transmission connecting rod 2 swings downwards. The second end of the transmission connecting rod 2 drives the actuating block 11 to swing downwards, and the actuating block 11 drives the scraper 1 to swing around the first support shaft 12 to a second position where it extends into the roller brush 6. At this time, because the trigger rod 41 is driven... The brush 6 swings downwards, triggering the micro switch 51, which in turn controls the roller brush motor to reverse, thereby driving the roller brush 6 to rotate counterclockwise. The comb teeth 13 can clean the hair wrapped around the roller brush 6. After cleaning is completed, the pedal 4 is released, and the trigger rod 41 is released from contact with the micro switch 51 under the action of the tension spring. The roller brush motor switches to forward rotation, thereby driving the roller brush 6 to rotate clockwise. The roller brush 6 performs normal cleaning and dust removal work on the ground, while the scraper 1 returns to the first position under the action of the torsion spring. Therefore, the scraper 1 will not interfere with the normal operation of the roller brush 6.

[0045] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
