Floor brushes and cleaning equipment

Abstract

This invention relates to a floor brush for a vacuum cleaner. The floor brush includes a brush body, a first light-emitting device, and a second light-emitting device. The brush body includes a receiving cavity for accommodating cleaning components. The first and second light-emitting devices are respectively mounted on the front and rear sides of the brush body. The brush body is lateral to the direction in which it travels back and forth on the surface to be cleaned. The first light-emitting device illuminates the cleaned area on the front side of the brush body, and the second light-emitting device illuminates the cleaned area on the rear side of the brush body. The first light-emitting device illuminates the cleaned area on the front side of the brush body, and the second light-emitting device illuminates the cleaned area on the rear side of the brush body. Together, they help the user check whether the cleaned areas on the front and rear sides of the brush body are clean. If the cleaned areas are not completely cleaned, they can be cleaned again promptly.

8. Spawn according to request item 1 or 4, where, The floor brush includes a detection device electrically connected to a control board. The detection device is installed on the floor brush body and is connected to the first light-emitting device and the second light-emitting device respectively. The detection device is used to detect the travel direction of the floor brush body and output a travel direction signal to the control board. The control board is used to control the first light-emitting device and the second light-emitting device to emit light selectively or simultaneously when triggered by the travel direction signal.

9. Based on request item 1, the land is refreshed, where, The floor brush body includes: a main housing, to which the cleaning component is rotatably connected; and a brush cover, connected to the main housing and covering the cleaning component, wherein at least one of the first light-emitting device and the second light-emitting device is mounted on the brush cover.

10. Based on request item 9, the land is refreshed, among which, At least one of the first light-emitting device and the second light-emitting device is installed on the outer wall of the brush cover facing away from the receiving cavity; or, the brush cover is provided with a light-emitting hole, at least one of the first light-emitting device and the second light-emitting device is located in the receiving cavity and installed on the inner wall of the brush cover facing the receiving cavity, and the light emitted by the first light-emitting device and the second light-emitting device illuminates the surface to be cleaned through the light-emitting hole; or, the brush cover includes at least two layers of cover body stacked on top of each other, and at least one of the first light-emitting device and the second light-emitting device is located between the two layers of cover body.

11. Based on request item 10, [the following is likely a separate, unrelated sentence:] ... The first light-emitting device and the second light-emitting device include a light source and a light shaping component. The light shaping component is used to receive the light beam emitted by the light source and guide the light beam to the surface to be cleaned, so that the light and shadow area of ​​the light source on the surface to be cleaned is a fan-shaped area. The edges of the two horizontal ends of the floor brush body are located within the fan-shaped area, or the edges of the two horizontal ends of the floor brush body are located outside the fan-shaped area, and the distance between them and the boundary of the fan-shaped area is less than 20mm.

12. Based on request item 11, the land is refreshed, where, The angle of the sector is 80°.

13. Based on request item 9, the land is refreshed, among which, Both the first light-emitting device and the second light-emitting device include a light source and a control harness.
