Description

Technical Field

[0001] This utility model relates to the field of wind-powered floor brush technology, specifically to a wind-powered carpet cleaning brush and cleaning device. Background Technology

[0002] Most current wind-driven floor brushes use a design where a fan drives a roller brush via a belt. There is an air inlet channel between the fan and the roller brush. Dry dust removal is mainly achieved by rotating the roller brush. These types of floor brushes generally rely on a single air duct structure, and the roller brush encounters significant resistance on carpets, making it unable to rotate and difficult to meet carpet cleaning needs.

[0003] Existing technologies have significant shortcomings:

[0004] 1. The single air duct design prevents airflow from entering smoothly during water intake, causing blockage and preventing effective water intake;

[0005] 2. Conventional wind-driven floor brushes mainly rely on a fan wheel to drive the roller brush via a belt, which cannot handle scenarios with high roller brush resistance.

[0006] Patent document CN222217763U discloses a floor brush assembly and a vacuum cleaner. The floor brush assembly includes: a floor brush housing; a roller brush assembly disposed within the floor brush housing and connected to the floor brush housing via a connecting assembly; and a connecting assembly located at both ends of the roller brush assembly, including a connecting shaft, a connecting arm, and a roller brush connecting part. The two ends of the connecting arm are respectively connected to the connecting shaft and the roller brush connecting part. The connecting shaft is installed within the floor brush housing, and the roller brush connecting part is connected to the roller brush assembly. The connecting arm and the roller brush connecting part can drive the roller brush assembly to rotate within a certain range around the connecting shaft, allowing the roller brush assembly to adjust its relative position within the floor brush housing according to different surfaces to be cleaned. This reduces the friction of the floor brush assembly on high-pile, high-resistance carpets. However, the aforementioned single-duct solution still has the problem of easily getting stuck when in close contact with the surface being cleaned. Utility Model Content

[0033] This utility model discloses a wind-driven carpet cleaning brush and cleaning device. The internal cavity of the device has two channels: a water inlet and an air inlet. This ensures that even when the water inlet is in close contact with the surface being cleaned, there is still a certain amount of air intake to drive the impeller to rotate. At the same time, a reduction gear assembly serves as the transmission structure between the impeller and the roller brush, increasing the speed ratio between the impeller and the roller brush, increasing the torque of the roller brush, and preventing the roller brush from stopping due to high friction from surfaces such as carpets.

[0034] According to the wind-driven carpet cleaning brush provided by this utility model, such as Figure 1-5 As shown, the device includes an upper cover 1, a lower cover assembly 2, and a connecting pipe 3.

The lower cover assembly 2 is provided with an air inlet 101 and a water suction inlet 102 at its bottom. Inside the housing, a fan wheel 7 and a roller brush 4 are installed. The fan wheel 7 is connected to the roller brush 4 via a reduction gear set. Air enters the housing through the air inlet 101 and the water suction inlet 102 and moves toward the rear end of the housing, driving the fan wheel 7 to rotate. The fan wheel 7 drives the roller brush 4 to rotate via the reduction gear set.

[0035] When the cleaning brush is cleaning, the water suction device provides suction through the pipe 3. Some air and sewage enter the cavity inside the housing through the water suction port 102. At the same time, air enters the cavity through the air inlet 101 and drives the impeller 7. Through the dual-channel design, the cavity where the impeller 7 is located has two channels: the water suction port 102 and the front air inlet 101. This ensures that the water suction port 102 has a certain amount of air intake to drive the impeller 7 to rotate when it is in close contact with the surface being cleaned.

[0036] Preferably, such as Figure 3 As shown, the housing includes a roller brush mounting cavity and a windmill mounting cavity from front to back, where a roller brush 4 and a windmill 7 are respectively mounted. The small gear in the reduction gear set is installed in the windmill mounting cavity and is coaxially and fixedly connected to the windmill 7. The large gear in the reduction gear set is installed in the roller brush mounting cavity and is coaxially and fixedly connected to the roller brush 4. A roller brush opening is provided at the bottom of the roller brush mounting cavity, corresponding to the roller brush 4. The roller brush opening is located at the front end of the water intake 102, which communicates with the windmill mounting cavity. A partition is provided between the roller brush mounting cavity and the windmill mounting cavity, and an internal air inlet 104 is provided on the partition. Air enters the roller brush mounting cavity through the air inlet 101 and then enters the windmill mounting cavity through the internal air inlet 104. In a preferred embodiment, the area of ​​the internal air inlet 104 is less than half the area of ​​the water intake 102. The air inlet 101 is located at the front end of the lower cover assembly 2 and communicates with the roller brush mounting cavity. The water inlet 102 is an elongated groove structure extending along the axial direction of the roller brush 4, and the length of the water inlet 102 is greater than or equal to the length of the roller brush 4.

[0037] In a preferred embodiment, the reduction gear set includes a first reduction gear set 5 and a second reduction gear set 6; the large gear in the first reduction gear set 5 is coaxially and fixedly connected to the roller brush 4, the small gear in the first reduction gear set 5 is coaxially and fixedly connected to the large gear in the second reduction gear set 6, and the small gear in the second reduction gear set 6 is coaxially and fixedly connected to the impeller 7. By using two or more sets of reduction gears, the rotational speed ratio between the impeller 7 and the roller brush 4 is increased, the torque of the roller brush 4 is increased, and the roller brush 4 is prevented from stopping due to high friction from surfaces such as carpets.

[0038] The cleaning device provided by this utility model includes a cleaning device body and the wind-driven carpet cleaning brush. The water absorption device of the cleaning device body is connected to the pipe 3 to provide air suction.
