Vacuum dust collector

Abstract

The invention discloses a vacuum dust collector, which comprises a machine body (1), wherein the machine body (1) comprises an upper cover (2) and a bottom shell (3); a dust collecting barrel (5) is arranged in the right end of the machine body (1) and clamped with the upper cover (2) of the machine body (1); the bottom of the dust collecting barrel (5) is provided with a limiting groove (10); the bottom shell (3), which is positioned below the dust collecting barrel (5), of the dust collector is provided with a bottom shell upper cover (11); the left end part of the bottom shell upper cover (11) is hinged with a locking plate; the locking plate (7) is positioned under the limiting groove (10); and the shape and size of the limiting groove (10) are correspondingly matched with those of the locking plate (7). The vacuum dust collector is provided with an automatic locking mechanism which can automatically lock the dust collecting barrel when the dust collecting barrel is erected, so that the dust collecting barrel is prevented from falling off from the machine body and the service life of the dust collecting barrel is prolonged.

Description

technical field [0001] The invention relates to the technical field of mechanical dust removal, in particular to a 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 vacuum in the vacuum cleaner,...

Problems solved by technology

[0007] However, when the vacuum cleaner user is carrying the machine, it is easy to misoperate the handle 6 on the dust collecting tube 5, that is, the thumb will be pressed on the position of the release button 7 of the handle 6 on the dust collecting tube 5, resulting in the collection When the dust tube 5 was erected (moving direction such as figure 1 (indicated by the arrow in the middle) the dust collection cylinder 5 is easy to fall off from the machine body 1, resulting in damage to the dust collection cylinder 5, greatly reducing the overall service life of the dust collection cylinder 5 of the vacuum cleaner, and making the vacuum cleaner unable to use normally, which seriously affects the life of the vacuum cleaner user.
