Abstract

The invention provides a dust collector. The dust collector comprises a case, a wheel body, a limiting plate and a plurality of salient points, wherein a fixed mount is arranged on the case; a wheel body sleeves the fixed mount and can rotate relative to the fixed mount, and a gap is reserved between the wheel body and the fixed mount; the limiting plate is connected with the case to limit the wheel body on the fixed mount; and the plurality of salient points are arranged on the fixed mount to support the wheel body. According to the dust collector provided by the invention, the gap is reserved between the fixed mount of the case and the wheel body to ensure that the wheel body can rotate relative to the fixed mount, and the plurality of salient points are arranged on the fixed mount to support the wheel body and greatly reduce the contact area between the wheel body and the fixed mount, so that the friction force on the wheel body during rotating is reduced, namely the flexibility of rotation of the wheel body is improved to facilitate the use by a user, thereby greatly improving the comfortableness of the product.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a vacuum cleaner. Background technique [0002] At present, the structure of the wheel of the vacuum cleaner of related art, such as figure 1 As shown, the wheel body 30' is buckled on the base 21' of the casing 10' through the buckle in the center; the wheel body 30' of this structure has the following problems: [0003] 1. The mating surface of the wheel body 30' and the base 21' has friction in the axial and radial directions, and the friction surface is relatively large, so the rotation flexibility of the wheel body 30' is relatively poor. When the user drags the vacuum cleaner to work, will feel more laborious; [0004] 2. The material of the wheel body 30' is polypropylene or acrylonitrile-butadiene-styrene copolymer, and its friction resistance and lubrication performance are relatively poor, resulting in inflexible movement and short life of the wheel body 30'. Con...
