Technical Field

The invention belongs to the field of cleaning equipment, and particularly relates to a universal electric floor brush.

Background

Floor brushes are well known for use in floor cleaning and are an important dust extraction component of cleaning equipment. The specific floor brush comprises a brush seat with a dust collection port and brush rolls arranged at the bottom of the brush seat, wherein the number of the brush rolls is two, the two brush rolls are arranged at two ends of the brush seat in parallel, however, in the floor brushing operation, a semi-closed negative pressure space is formed between the floor brush connected to the cleaning equipment and the ground, and under the action of negative pressure, the brush rolls of the floor brush the sundries on the ground towards the dust collection port so as to realize the cleaning of the sundries.

Therefore, the electric floor brush used in the market at present is easy to have the following problems in the actual use process:

1) most of electric floor brushes in the market are only provided with one brush roll, and one side of the brush roll is provided with a dust collection port, so that dust can be pushed to the direction of the dust collection port from the brush roll during working, and thus, part of dust easily passes through the dust collection port and escapes from one side of the floor brush, which is far away from the brush roll, and the escaped dust is lost and cannot be completely absorbed after the floor brush sweeps the ground, so that a user needs to repeatedly push and pull the floor brush to sweep, the cleaning effect is poor, and the efficiency is low;

2) the floor brushes are also arranged on the market, although two brush rolls are designed, the sizes and the materials of the two brush rolls are not consistent, and an effective dust suction opening shunting device is lacked between the two brush rolls, so that when the floor brushes work, the effective negative pressure area between the dust suction opening and the brush rolls is small, and the dust suction effect is not ideal;

3) the existing electric floor brush is lack of a universal wheel device, and during use, the electric floor brush can only be pushed and pulled forwards and backwards along the rotating direction of the brush roller, and is stiff in machinery, low in flexibility, time-consuming and labor-consuming in operation, high in labor intensity of operators and low in cleaning efficiency.
