Pretreatment device for preventing hair from winding for household sweeping robot

Abstract

The invention provides a pretreatment device for preventing hair from winding for a household sweeping robot, and belongs to the technical field of household appliances. The pretreatment device comprises a brush shaft body, the brush shaft body is sleeved with a bearing sleeve, a concentric ring base is slidably arranged between the bearing sleeve and the brush shaft body, and blades are uniformly connected to the outer shaft side of the concentric ring base; sliding plates are evenly connected to the outer shaft side of the bearing sleeve in an inserted mode, on-off assemblies are connected between the inner sides of the sliding plates and the bearing sleeve, and converging and fastening assemblies are evenly arranged on the sliding plates. According to the pretreatment device for preventing hair from winding for the household sweeping robot, through the combined action of the brush shaft body, the bearing sleeve, the sliding plates, the on-off assemblies, the driving sleeve, the concentric ring base, the converging and fastening assemblies and the blades, axial fragmentation treatment is effectively conducted on wound hair, and the device has the advantages of being better in fragmentation effect, high in precision, clear in fragmentation target and the like; and meanwhile, the service life of the blades is correspondingly prolonged.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to a hair entanglement prevention pretreatment device for a household sweeping robot. Background technique [0002] As a household appliance that is more popular and popular among young people, the sweeping robot has the advantages of high intelligence, convenience and efficiency. It is generally circular and automatically cleans the ground according to the set route. It has brought great convenience to our daily life, and has become a commonly used household appliance in office workers or modern families. [0003] However, during the cleaning process of the robot, it is easy for the hair to be entangled and gathered on the brush shaft, which will not only prevent the robot from inhaling dust and affect the cleaning effect of the robot, but also affect the rotation of the brush shaft.

Problems solved by technology

[0003] However, during the cleaning process of the robot, it is easy for the hair to be entangled and gathered on the brush shaft, which will not only prevent the robot from inhaling dust and affect the cleaning effect of the robot, but also affect the rotation of the brush shaft. The stuck brush shaft seriously reduces the cleaning efficiency and effect of the robot. Secondly, it is troublesome to clean the hair entangled and gathered on the brush shaft. Cutting parts such as blades are installed in other positions to directly cut the incoming hair, but not only the cutting effect is average, but also the blade is easily hit by other fast-inhaled dust particles because it is in the working state for a long time, which further reduces the hair loss of the blade. The effect of hair cutting treatment, while reducing the service life of the blade
