Embodiment Construction

[0026] The present invention will be described in detail below with reference to the drawings and examples.

[0027] The roller structure of vacuum cleaner of the present invention, as figure 1 as shown,

[0028] The upright vacuum cleaner 1 is roughly divided into the following parts: the vacuum cleaner includes: a suction pipe body 10 supporting the vacuum cleaner 1, a casing 20 connected to the suction pipe body 10 and vertically upright; a handle 30 is formed on the upper part of the casing 20; the handle 30 Formed integrally with the casing 20 . A switch assembly 40 for controlling the operation of the vacuum cleaner 1 is formed on one side of the handle 30; a power cord 22 for supplying power to the fan motor is formed on one side of the housing 20; the power cord 22 should be made elongated. A suction hose 24 is formed on the rear side of the casing 20 . A connection pipe 26 is attached to a side surface of the casing 20 .

[0029] Such as figure 1 As shown, a roll...

Abstract

The invention relates to a trolley structure for a dust collector. The dust collector comprises a shell, a suction tube body, a handle, a soft suction tube and a connecting tube. The two sides at the back of the bottom surface of the suction tube body are respectively provided with a trolley formed by shaft connecting wheels and oil storage tanks are arranged on the ambient surfaces of the shaft hole of the wheels. As the shaft hole cooperated with each wheel is provided with the oil storage tank which is stored with solid fat that can lubricate the wheels and the shaft for a long time; the trolley is effectively prevented from rotating to generate noises.

Description

technical field [0001] The invention belongs to the field of vacuum cleaners, and in particular relates to a roller structure of a vacuum cleaner which is provided with an oil storage tank for storing grease in the rollers to ensure the lubrication of the roller rotation and effectively prevent noise. Background technique [0002] Vacuum cleaner is a kind of household appliance for indoor cleaning and sanitation, which is used to remove dust from floors, carpets, walls, furniture, clothing and various gaps. Generally speaking, a vacuum cleaner mainly includes a suction device and a suction pipeline. The suction device mainly formed by a motor and a fan is arranged in the body. The suction pipeline includes a suction head and a suction pipe. The air port communicates with the air inlet of the fan inside the body through the telescopic pipe and flexible pipe of the suction pipe. [0003] When the vacuum cleaner is running, the motor drives the impeller of the fan to rotate at...
