Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to the layout structure of floor brushes used in cleaning equipment. Background Technology

[0002] In the use of cleaning equipment (such as vacuum cleaners and robotic vacuum cleaners), the floor brush, as a core component that directly contacts the surface to be cleaned, directly affects cleaning efficiency and effectiveness through its structural design. Existing floor brush structures suffer from the following problems:

[0003] Most floor brushes use a single roller design, which can only sweep up garbage by rotating in one direction. They are not effective at collecting larger particles of garbage or debris such as hair, and are prone to being missed during sweeping.

[0004] Some dual-roller floor brushes use a co-rotation method. When the rollers rotate, they push the debris to both sides, causing the debris to not be concentrated at the suction port and reducing the suction efficiency.

[0005] The unreasonable design of the relative position between the suction channel and the roller brush makes it easy for the debris swept up by the roller brush to escape from the edge of the suction channel and cannot be effectively sucked in.

[0006] The complex drive structure makes it difficult to guarantee the synchronization and stability of the dual roller brush rotation, affecting the consistency of cleaning effect.

[0007] Therefore, there is an urgent need for a floor brush layout structure that can solve the above problems in order to improve the cleaning efficiency and effectiveness of cleaning equipment. Utility Model Content

[0008] To overcome the shortcomings of the existing technology, this utility model provides a floor brush layout structure for use in cleaning equipment, aiming to solve the problems of low cleaning efficiency, poor garbage accumulation effect, and incomplete dust suction of existing floor brushes.

[0009] To achieve the above and other related objectives, the technical solution provided by this utility model is: a floor brush layout structure applied in cleaning equipment, comprising:

[0010] A floor brush head, wherein a roller brush cavity is formed at the bottom of the floor brush head, and a dust suction channel communicating with the roller brush cavity is provided on the floor brush head;

[0011] A roller brush assembly, comprising a main roller brush and an auxiliary roller brush, wherein the main roller brush and the auxiliary roller brush are both disposed in the roller brush cavity and arranged in parallel at intervals, and the dust suction channel is disposed toward the space between the main roller brush and the auxiliary roller brush;

[0012] A drive assembly is disposed in the brush head and configured to drive the main roller brush and the auxiliary roller brush to rotate synchronously in opposite directions.

[0013] The preferred technical solution is that the outer diameter of the main roller brush is larger than the outer diameter of the auxiliary roller brush.

[0014] A preferred technical solution is that the main roller brush and the auxiliary roller brush are arranged sequentially along the forward direction of the brush head, the main roller brush is configured to rotate counterclockwise, and the auxiliary roller brush is configured to rotate clockwise.

[0015] The preferred technical solution is as follows: the driving component includes a motor and a transmission gear set, the motor is fixed in the brush head and is simultaneously connected to the main roller brush and the auxiliary roller brush through the transmission gear set.

[0016] A preferred technical solution is as follows: the top of the roller brush cavity is formed with a downwardly extending partition 1 and partition 2, the partition 1 and partition 2 are located between the main roller brush and the auxiliary roller brush and form a dust suction cavity, and the dust suction channel is connected to the dust suction cavity.

[0017] The preferred technical solution is that the bottom end of the first partition is flush with the top side of the auxiliary roller brush, and the bottom end of the second partition is close to the top side of the auxiliary roller brush.

[0018] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:

[0019] The main and auxiliary roller brushes rotate synchronously in opposite directions, which can gather the garbage on the surface to be cleaned into the space between them, solving the problem of scattered garbage that is difficult to clean in the existing technology and improving the garbage gathering effect;

[0020] The suction channel faces the space between the main and auxiliary roller brushes and forms a suction chamber through the partition, which allows the accumulated garbage to be quickly and effectively sucked into the suction channel, reducing garbage escape and solving the problem of incomplete suction.

[0021] The main roller brush has a larger outer diameter than the auxiliary roller brush, which can clean different types and sizes of garbage separately, thus improving the comprehensiveness of cleaning.

[0022] The drive assembly is driven by a transmission gear set, which ensures the synchronization and stability of the rotation of the main and auxiliary roller brushes, ensuring the consistency of the cleaning effect and solving the problem of unstable cleaning effect caused by the complexity of the existing drive structure.
