Description

Technical Field

[0001] The present application relates to the technical field of floor brushes, and in particular to a dual-air channel cleaning floor brush. Background Art

[0002] Floor brushes are primarily used for cleaning floors. Brushes designed for cleaning large areas are generally considered floor brushes. There are many different types of floor brushes, primarily made from wood and plastic injection-molded materials. The main materials used for these brushes include coir, sisal, nylon, plastic, and horsetail hair. The hair varies in thickness and hardness, depending on the application. The handle connects to the brush body with a metal connector.

[0003] Chinese patent publication number CN101756673A discloses a floor brush for a vacuum cleaner, comprising a shell having an inner cavity, a pipe connected to the inner cavity, a bracket disposed in the inner cavity, and a brush strip mounted on the bracket. The pipe is disposed above the shell so as to be rotatable left and right, and the bracket is disposed at the lower part of the shell so as to be rotatable forward and backward. The operating handle on the vacuum cleaner is connected to the pipe on the floor brush.

[0004] During the use of the above technology, the suction force connected by the pipe will be concentrated in the middle position of the shell, resulting in less suction at both ends of the shell. When the brush bar is cleaning the floor, the dirt at the end of the shell may not be sucked in by the vacuum cleaner through the pipe due to the weak suction at the end of the shell. In this way, the user needs to clean the position of the end of the shell on the floor again, which will increase the user's workload and the time spent on cleaning, and there are shortcomings. Utility Model Content

[0005] In order to improve the problem that the suction force at the end of the shell becomes smaller and the dirt cannot be sucked up, the present application provides a dual-air channel cleaning brush.

[0006] The present application provides a dual-air channel cleaning brush that adopts the following technical solution:

[0007] A dual-air channel cleaning brush comprises a shell and a base plate. The interior of the shell is hollow and the bottom is open. The base plate is detachably arranged on the open end of the shell. The shell is connected to a dust exhaust pipe joint, and the dust exhaust pipe joint is used to connect with a vacuum cleaner. A front end shaft is rotatably arranged on the shell, and a front end dust removal roller is coaxially sleeved on the front end shaft. A front end dust suction port for rotating the front end dust removal roller is provided on the base plate. A driving assembly for driving the front end shaft to rotate is provided on the shell. A dust collecting assembly is provided on the shell, and the dust collecting assembly is used to concentrate dust at both ends of the front end dust removal roller in the middle of the front end dust removal roller.

[0008] By adopting the above technical solution, the user connects the dust exhaust pipe joint to the vacuum cleaner, and then drives the front end shaft through the driving component to drive the front end dust removal roller to rotate. The front end dust removal roller sweeps up the dust on the ground. Part of the dust is swept into the shell by the front end dust removal roller, and the other part of the dust is sucked into the shell by the vacuum cleaner through the dust suction port. At the same time, the dust collecting component will concentrate the dust at both ends of the front end dust removal roller in the middle of the front end dust removal roller, thereby reducing the possibility that the dust at the end of the front end dust removal roller cannot be cleaned due to the decrease in suction force.

[0009] Optionally, the drive assembly includes a main shaft rotatably arranged on the shell and parallel to the front end shaft, a drive motor electrically connected to the control system is provided on the shell, the main shaft is coaxially arranged on the output shaft of the drive motor, and a first transmission belt is wound between the main shaft and the front end shaft.

[0010] By adopting the above technical solution, the control system starts the drive motor, the drive motor drives the main shaft to rotate, the main shaft drives the front end shaft to rotate through the first transmission belt, and the front end shaft drives the front end dust removal roller to rotate synchronously, thereby achieving the function of cleaning dust.

[0011] Optionally, the front-end dust removal roller includes a first dust removal roller and a second dust removal roller which are symmetrically arranged, the first transmission belt is located between the first dust removal roller and the second dust removal roller, a rear-end shaft parallel to the main shaft is rotatably arranged on the shell, a second transmission belt is wound between the main shaft and the rear-end shaft, a rear-end dust removal roller is coaxially arranged on the rear-end shaft, a rear-end dust suction port for the rear-end dust removal roller to rotate is opened on the bottom plate, and the rear-end dust removal roller is located between the first dust removal roller and the second dust removal roller.

[0012] By adopting the above technical solution, the main shaft drives the rear end shaft to rotate through the second transmission belt, and the rear end shaft drives the rear end dust removal roller to rotate synchronously. The rear end dust removal roller cleans the dust between the first dust removal roller and the second dust removal roller through the rear end dust suction port. At the same time, since the rear end dust suction port is closer to the dust exhaust pipe joint, the rear end dust suction port will have greater suction force, thereby sucking in the dust remaining between the first dust removal roller and the second dust removal roller, thereby improving the cleaning degree of the ground.

[0013] Optionally, the dust collecting assembly includes a guide plate arranged in the shell and located at both ends of the front dust removal roller, the guide plate, the shell and the bottom plate form a dust blowing channel, a blast blade is rotatably provided on the shell and located in the dust blowing channel, an air inlet hole communicating with the dust blowing channel is opened between the inner and outer side walls of the shell, and a rotating part for driving the blast blade to rotate is provided on the shell.

[0014] By adopting the above technical solution, the rotating part drives the blast blade to rotate, and the rotation of the blast blade forms an airflow in the dust blowing channel. The external air flows into the dust blowing channel through the air inlet hole. The airflow flows to the end of the front dust removal roller under the guidance of the dust blowing channel. The airflow blows the dust at the end of the front dust removal roller to the middle position of the front dust removal roller, thereby reducing the possibility that the dust at the end of the front dust removal roller cannot be cleaned.

[0015] Optionally, the rotating member includes a bracket arranged on the shell, an impeller shaft is rotatably arranged on the bracket, the blast blades are arranged on the impeller shaft, and the impeller shaft and the rear end shaft are driven by a bevel gear set.

[0016] By adopting the above technical solution, the rear end shaft drives the impeller shaft to rotate through the bevel gear set, and the impeller shaft drives the blast blades to rotate. The rotation of the blast blades forms an airflow in the dust blowing channel.

[0017] Optionally, a dust guide plate is symmetrically provided on the shell with respect to the dust exhaust pipe joint, and the dust guide plate is located between the dust exhaust pipe joint and the rear end dust removal roller.

[0018] By adopting the above technical solution, the negative pressure airflow generated by the vacuum cleaner flows to the inside of the shell through the dust exhaust pipe joint. Under the action of the dust guide plate, the dust inside the shell can be better sucked out by the dust exhaust pipe joint, which is beneficial to reduce the possibility of dust accumulation inside the living room.

[0019] Optionally, a partition plate is provided in the shell, and the partition plate is used to separate the drive motor from the front dust removal roller, and the drive motor from the rear dust removal roller.

[0020] By adopting the above technical solution, it is beneficial to reduce the impact of dust sucked into the shell on the drive motor, which is beneficial to increasing the service life of the drive motor.

[0021] Optionally, a plurality of bristles are evenly arranged circumferentially on the first dust removal roller, and the bristles are spirally wound around the first dust removal roller.

[0022] By adopting the above technical solution, the spiral bristles on the first dust removal roller and the spiral bristles on the second dust removal roller concentrate dust at the middle position of the front end shaft during the rotation of the front end shaft, thereby improving the dust cleaning effect.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The user connects the dust exhaust pipe joint to the vacuum cleaner, and then drives the front shaft through the drive assembly to drive the front dust removal roller to rotate. The front dust removal roller sweeps up the dust on the ground. Some of the dust is swept into the shell by the front dust removal roller, and the rest of the dust is sucked into the shell by the vacuum cleaner through the suction port. At the same time, the dust collection assembly will collect the dust at both ends of the front dust removal roller in the middle of the front dust removal roller, thereby reducing the possibility that the dust at the end of the front dust removal roller cannot be cleaned due to the decrease in suction force;

[0025] 2. The main shaft drives the rear end shaft to rotate through the second transmission belt, and the rear end shaft drives the rear end dust removal roller to rotate synchronously. The rear end dust removal roller cleans the dust between the first dust removal roller and the second dust removal roller through the rear end dust suction port. At the same time, because the rear end dust suction port is closer to the dust exhaust pipe joint, the rear end dust suction port has a stronger suction force, thereby sucking in the dust remaining between the first dust removal roller and the second dust removal roller, thereby improving the cleaning degree of the ground;

[0026] 3. The rotating part drives the blast blade to rotate. The rotation of the blast blade forms an airflow in the dust blowing channel. The external air flows into the dust blowing channel through the air inlet. The airflow flows to the end of the front dust removal roller under the guidance of the dust blowing channel. The airflow blows the dust at the end of the front dust removal roller to the middle position of the front dust removal roller, thereby reducing the possibility that the dust at the end of the front dust removal roller cannot be cleaned.

The impeller shaft 852 and the rear end shaft 9 are driven by a bevel gear set 853.

[0042] The rear end shaft 9 drives the impeller shaft 852 to rotate through the bevel gear set 853, and the impeller shaft 852 drives the blast blades 83 to rotate. The rotation of the blast blades 83 forms an airflow in the dust blowing channel 82, and the external air flows into the dust blowing channel 82 through the air inlet 84. The airflow in the dust blowing channel 82 flows to the end of the front dust removal roller 5 under the guidance of the dust blowing channel 82. The airflow blows the dust swept up by the end of the front dust removal roller 5 to the middle position of the front dust removal roller 5, and is sucked into the shell 1 through the middle of the front dust suction port 6 and the rear end dust suction port 12.

[0043] The implementation principle of a dual-air channel cleaning floor brush in an embodiment of the present application is as follows: the user connects the dust exhaust pipe connector 3 to the vacuum cleaner, and then starts the drive motor 72 through the control system. The drive motor 72 drives the main shaft 71 to rotate, and the main shaft 71 drives the front end shaft 4 to rotate through the first transmission belt 73. The front end shaft 4 drives the first dust removal roller 51 and the second dust removal roller 52 to rotate synchronously. The bristles 15 on the first dust removal roller 51 and the second dust removal roller 52 sweep up the dust on the ground through the front dust suction port 6, and accumulate in the middle position of the front end shaft 4 under the action of the spiral bristles 15.

[0044] At the same time, the main shaft 71 drives the rear end shaft 9 to rotate through the second transmission belt 10, and the rear end shaft 9 drives the rear end dust removal roller 11 to rotate. The rear end dust removal roller 11 sweeps up the dust on the ground between the first dust removal roller 51 and the second dust removal roller 52 through the rear end dust suction port 12. During the rotation of the first dust removal roller 51, the second dust removal roller 52 and the rear end dust removal roller 11, the negative pressure airflow from the vacuum cleaner passes through the front end dust suction port 6 and the rear end dust suction port 12 to suck the dust swept up on the ground into the shell 1, and under the action of the dust guide plate 13, it is sucked into the vacuum cleaner through the dust exhaust pipe joint 3.

[0045] The rear end shaft 9 drives the impeller shaft 852 to rotate through the bevel gear set 853, and the impeller shaft 852 drives the blast blades 83 to rotate. The rotation of the blast blades 83 forms an airflow in the dust blowing channel 82, and the external air flows into the dust blowing channel 82 through the air inlet 84. The airflow in the dust blowing channel 82 flows to the end of the front dust removal roller 5 under the guidance of the dust blowing channel 82.
