Vacuum cleaner brush head

Abstract

The invention discloses a vacuum cleaner brush head, comprising a brush head main body which is eudipleural, an outer telescopic section, a middle telescopic section and a connection block, wherein the connection block is connected with one end of the brush head main body, and the two ends of the middle telescopic section are respectively connected with the other end of the brush head main body and one end of the outer telescopic section. The invention has the beneficial effects that since the brush head is of a multi-section structure and can be stretched out and drawn back freely, the brush head can be adjusted according to positions to be cleaned for adaptability, and the brush head can be folded simultaneously to adapt to various surfaces to be cleaned, thereby enhancing the cleaning efficiency and realizing the multifunction of one brush.

Description

technical field [0001] The invention relates to a vacuum cleaner; in particular, it relates to a retractable and foldable brush head of the vacuum cleaner. 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, forming an instantaneous vacu...

Problems solved by technology

[0008] The brush head of the vacuum cleaner is composed of a rectangular bottom shell and an upper cover. There is an air suction port, the vacuum motor works after the current is introduced, the dust on the cleaning surface enters the suction head of the vacuum cleaner through the suction nozzle on the end face of the conical shell, passes through the air inlet slot, the suction pipe connection, the suction hose, The passing device enters the dust collection part of the accumulation and suction. The brush head of the vacuum cleaner is divided into two types that can be rotated as a whole and partially rotated. It is very difficult to clean, even if the brush head is inserted into the corner, the brush head will often be stuck, so when cleaning the corner of the floor or the corner between the wall and the wall, it is necessary to replace another brush head. cause inconvenience
