Although the above floor brush comb can clean the hair wrapped around the roller brush, the tooth tips of the comb will interfere with the work of the roller brush, thereby affecting the normal work of the roller brush.

[0004] Therefore, the prior art still needs to be improved and developed. Utility Model Content

[0005] The purpose of the utility model is to provide a roller brush hair winding cleaning structure to address the defects and shortcomings of the prior art. The hair scraper can be switched between a second position extending into the interior of the roller brush and a first position not in contact with the roller brush by opening and closing a driving mechanism connected to the hair scraper.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] The utility model provides a roller brush hair entanglement cleaning structure, comprising a scraper rotatably arranged in a shell body, wherein the scraper is arranged along a length direction parallel to the roller brush, and the scraper is driven by a driving mechanism to swing to a second position extending into the interior of the roller brush; the scraper is connected to a first reset mechanism, and the first reset mechanism is used to reset the scraper from the second position to a first position not in contact with the roller brush.

[0008] Through the above-mentioned structural arrangement, when it is necessary to clean the hair wrapped around the roller brush, the drive mechanism can be turned on to swing the hair scraper to the second position extending into the interior of the roller brush. After the drive mechanism is turned off, the hair scraper is reset to the first position where it does not contact the roller brush under the action of the first reset mechanism, thereby not interfering with the normal operation of the roller brush.

[0009] According to the above scheme, the driving mechanism includes a pedal connecting rod and a transmission connecting rod which are respectively rotatably arranged in the shell; a pedal is provided on the first end of the pedal connecting rod, the second end of the pedal connecting rod is abutted against the first end of the transmission connecting rod, and the second end of the transmission connecting rod is abutted against the toggle block on the scraper; the scraper can be driven by the toggle block to swing to a second position extending into the interior of the roller brush.

[0010] Through the above-mentioned structural arrangement, when it is necessary to clean the hair wrapped around the roller brush, the pedal is pressed down to drive the pedal connecting rod and the transmission connecting rod to rotate so that the toggle block on the hair scraper swings downward, and the hair scraper is driven by the toggle block to swing forward and upward to the second position extending into the roller brush; after cleaning is completed, the pedal is released, and the hair scraper is reset to the first position not in contact with the roller brush under the action of the first reset mechanism, so as not to interfere with the roller brush in normal operation. That is, by pressing down or releasing the pedal, the hair scraper can be switched between the second position extending into the roller brush and the first position not in contact with the roller brush.

[0011] According to the above solution, the upper end of the scraper is provided with a first support shaft passing through horizontally, and the first support shaft is fixed in the housing. Through the above structural arrangement, the scraper is driven by the toggle block to swing around the first support shaft.

[0012] According to the above solution, the first reset mechanism is a torsion spring, which is arranged on the first support shaft, and is used to apply a force to the scraper to make the scraper swing from the second position to the first position. Through the above structural arrangement, after the scraper finishes its work, the pedal is released to eliminate the pressure applied to the toggle block, and the scraper can be quickly reset to the first position without contacting the roller brush under the action of the torsion spring.

[0013] According to the above solution, the lower end of the hair scraper is provided with a plurality of comb teeth arranged along the length direction of the roller brush, and the comb teeth are in a hook-shaped structure. By providing the comb teeth in a hook-shaped structure, the hair entangled on the roller brush can be easily cleaned.

The micro switch is triggered by a trigger rod provided at the bottom of the pedal, and 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 removing dust from the floor, the roller brush motor rotates forward, thereby driving the roller brush to rotate clockwise. When the pedal is pressed down, the trigger rod moves downward to trigger the micro switch, thereby controlling the roller brush motor to reverse, thereby driving the roller brush to rotate counterclockwise; when the pedal is released, the pedal swings upward under the action of the first reset mechanism, the pedal connecting rod, and the transmission connecting rod, thereby causing the trigger rod to release contact with the micro switch, and the roller brush motor switches to forward rotation. Through the above-mentioned structural setting, the forward or reverse state of the roller brush motor can be controlled by pressing down or releasing the pedal.

[0016] According to the above solution, the pedal connecting rod is connected with a second reset mechanism. By providing the second reset mechanism, the pedal connecting rod can be quickly reset after the pedal is released.

[0017] According to the above solution, the second reset mechanism is a tension spring, and the tension spring is arranged at the bottom of the second end of the pedal connecting rod.

[0018] When the pedal is pressed down, the second end of the pedal connecting rod 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 is quickly released from contact with the micro switch.

[0019] It is understandable that in order to quickly reset the pedal connecting rod, those skilled in the art may also configure the second reset mechanism to be a compression spring disposed at the bottom of the first end of the pedal connecting rod, or a torsion spring disposed on the pedal connecting rod according to actual needs.

[0020] According to the above solution, a second support shaft is provided through the middle of the transmission connecting rod, and the second support shaft is fixed in the housing. Through the above structural arrangement, the transmission connecting rod rotates around the second support shaft.

[0021] According to the above solution, a limit block is provided in the housing, and the limit block is located in front of the scraper. By providing the limit block, the swing of the scraper forward and upward can be limited to prevent the scraper from extending too deeply into the roller brush and affecting the rotation of the roller brush.
