[0032] The vacuum cleaner floor brush structure provided in this application includes a vacuum cleaner body, comprising a vacuum cleaner housing with a suction port; a coil disposed at the suction port; and a main control circuit board disposed within the vacuum cleaner body, the main control circuit board being electrically connected to the coil. By incorporating the coil to detect metal objects such as wires and iron blocks, the risk of vacuum cleaner pipe blockage or electric shock is prevented, ensuring product reliability.

[0033] like Figure 1 As shown, one embodiment of this application provides a vacuum cleaner floor brush structure, including:

[0034] The vacuum cleaner body 100 includes a vacuum cleaner housing 110, which has a suction port;

[0035] The coil 200 is positioned at the suction port; and

[0036] The main control circuit board 300 is installed inside the vacuum cleaner body 100 and is electrically connected to the coil 200.

[0037] The vacuum cleaner's floor brush structure is used for vacuuming. Dust, paper scraps, and other debris are sucked in through the suction port and then stored in the dust collection box.

[0038] A coil 200 is installed at the suction port, and is electrically connected to the main control circuit board 300. The main control circuit board 300 includes a metal detection IC (integrated circuit, microchip) and a resonant capacitor. The metal detection IC then communicates with the vacuum cleaner's MCU. The coil 200 and the resonant capacitor oscillate to generate a high-frequency electromagnetic field. Since the ground may contain not only dust and paper scraps but also objects with metal, such as wires and iron blocks, when a metal object approaches the coil 200, it induces a current, creating a reflected electromagnetic field. This reflected electromagnetic field superimposes on the electromagnetic field of the coil 200, changing the original voltage signal of the coil 200. The metal detection IC detects this voltage change and transmits the data to the MCU, which then determines whether metal is present.

[0039] Optionally, a filter screen is provided inside the suction port to prevent dust and dirt from clogging the airflow passage of the vacuum cleaner's floor brush structure and to maintain the suction power of the vacuum cleaner's floor brush structure.

[0040] Optionally, the filter screen includes at least one of steel wire mesh, microporous nylon cloth, and / or microporous sponge, without limitation.

[0041] The vacuum cleaner floor brush structure provided in this application includes a vacuum cleaner body 100, including a vacuum cleaner housing 110 with a suction port; a coil 200 disposed at the suction port; and a main control circuit board 300 disposed within the vacuum cleaner body 100, which is electrically connected to the coil 200. By incorporating the coil 200 to detect metal objects such as wires and iron blocks, the risk of vacuum cleaner pipe blockage or electric shock is prevented, ensuring product reliability.

Moreover, the coil 200 is mounted on the inner surface of the roller cover 130 via the coil circuit board 140, making installation more convenient and reliable.

[0045] Optionally, the vacuum cleaner floor brush structure provided in this application further includes a connecting wire 400. The first end of the connecting wire 400 is electrically connected to the coil 200, and the second end of the connecting wire 400 is provided with a first connecting terminal 500. The main control circuit board 300 is provided with a second connecting terminal 600 that mates with the first connecting terminal 500. The first connecting terminal 500 and the second connecting terminal 600 work together to achieve a quick-release electrical connection between the connecting wire 400 and the main control circuit board 300, making installation convenient and reliable.

[0046] Optionally, the vacuum cleaner floor brush structure provided in this application also includes an outer cover 150, which is installed on the vacuum cleaner body 100.

The vacuum cleaner housing 110 is provided with a through hole in the part corresponding to the wire passage space. The second connecting terminal 600 passes through the through hole and partially extends out of the through hole.

[0047] The wire passage space between the outer casing 150 and the vacuum cleaner housing 110 allows for better routing of the connecting wire 400. Furthermore, the main control circuit board 300 is located inside the vacuum cleaner housing 110, providing excellent protection for the main control circuit board 300. The second connecting terminal 600 extends out of the through hole for easy insertion into the first connecting terminal 500, making connection convenient.
