Embodiment Construction

[0029] The brush head of the vacuum cleaner of the present invention will be further described in detail in conjunction with the accompanying drawings and specific embodiments:

[0030] Such as figure 2 , image 3 As shown, the vacuum cleaner brush head of the present invention includes an intermediate bracket 10, a telescopic part 20 fixedly connected to both sides of the middle bracket 10 and symmetrically distributed on both sides thereof, and an end support part fixedly connected to the end of the telescopic part 20 30. The middle bracket 10 and the telescopic part 20 are arched upwards in the middle to increase the internal space of the brush head, which can expand and contract in the length direction of the brush head to increase the area of ​​the brush head.

[0031] While connecting the telescopic parts 20 on both sides, the middle bracket 10 is formed with a through hole 11 on its side and communicates with the telescopic tube 3 of the vacuum cleaner. The garbage a...

Abstract

The invention discloses a brush head of a dust collector, which comprises a middle support connected with an air inlet pipe, telescopic parts fixedly connected at two sides of the middle support, and end supporting parts fixedly connected at the ends of the telescopic parts, wherein each telescopic part has an organ type telescopic structure capable of extending along the length direction of the brush head. The length of the brush head can be changed as needed simply, and the initial length of the brush head is small, so that the brush head is suitable for sweeping small places such as windowsills or steps, and the like, and is easy to store; when the brush head is used for sweeping large-area planes, by only simply treading a pedal, the brush head can stretch out and draw back automatically, and the reutilization of tail gas of the dust collector can be realized, so that the dust collection efficiency and practicability can be improved to further improve the satisfactory degree of a user; and for the brush head, the structure is simple, and the application range is wide, so that the brush head is beneficial to wide production and popularization and has great practical production significance.

Description

technical field [0001] The invention relates to a vacuum cleaner; in particular, it relates to a vacuum cleaner brush head which can be arbitrarily stretched in the length direction. Background technique [0002] Generally, a vacuum cleaner is a device that uses a vacuum to generate suction to inhale air, make the air flow through various filters, filter foreign objects in the air, and clean the room. [0003] 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 suction head has a downward opening. The suction port communicates with the air inlet of the fan inside the body through the telescopic pipe and the flexible pipe of the suction pipe. When the vacuum cleaner is running, the motor drives the impeller of the fan to rotate at a high speed, exhausting the air in the vacuum cleaner, fo...
