Description

Air duct structure applied to dust collector

Technical Field

The invention relates to an air duct structure applied to a dust collector.

Background

As is well known, the operating principle of a cyclone cleaner is as follows: the motor of the dust collector rotates at a high speed, air is sucked from the suction inlet, a certain vacuum is generated in the dust cup, the airflow with dust sequentially passes through the ground brush, the connecting pipe, the handle, the hose, the main suction pipe and other accessories and enters the dust cup, the cyclone chamber in the dust cup enables the airflow to rotate at a high speed and generates strong centrifugal force to drive the dust to rotate and deposit, the separated dust with the size is rapidly fallen into the dust collecting chamber, the filtered air enters the motor through the filter plate, the air entering the motor flows out through the motor, is filtered by the post-motor filter device and then is discharged to the atmosphere. However, the air duct of the existing cyclone dust collector has a complex structure and a long length, so that the noise reduction effect is limited.

Disclosure of Invention

The invention aims to: provides an air duct structure applied to a dust collector.

The technical scheme of the invention is as follows: the utility model provides an air duct structure for on dust catcher, its includes the organism, is located the motor cover and the air-out wind channel of organism, the air-out wind channel is buckled along the motor cover by the air outlet of motor cover one side and is extended, buckles again and turns into motor cover opposite side.

On the basis of the technical scheme, the method further comprises the following auxiliary technical scheme:

the motor is vertically arranged, and the air inlet of the motor is positioned below the motor.

The air inlet duct is positioned below the dust cup, and the air outlet duct is positioned above the air inlet duct.

The other technical scheme of the invention is as follows: an air duct structure applied to a dust collector is characterized by comprising: the air conditioner comprises a machine body, a motor cover positioned in the machine body, an air inlet duct positioned below the motor cover, and an air outlet duct which is bent around the motor cover, extends and is positioned above the air inlet duct.

The invention has the advantages that: simple structure carries out the simplification with the air inlet duct and handles, shortens air inlet duct length, reduces dust catcher motor noise.

Detailed Description

Example (b): as shown in fig. 1-2, the present invention provides an embodiment of an air duct structure applied to a vacuum cleaner, which includes a lower body 12, an upper body 14 fastened to the lower body 12, a dust cup 20 movably disposed between the upper and

lower bodies

14, 12, a filter device 30 disposed under the dust cup 20, an air inlet duct 32 disposed under the filter device 30, a motor 40 housed in the upper and

lower bodies

14, 12, a motor cover 50 housing the motor 40 and having a motor outlet 52, and an air outlet duct 54 connected to the outlet 52. The upper and

lower bodies

14, 12 together form a body, and have a receiving cavity which receives the dust cup 20 and is partially opened outward.

The lower body 12 includes a receiving chamber 120 corresponding to the dirt cup 20 and receiving the filtering device 30, an air inlet 122 located in front of the receiving chamber 120, and an air outlet 124 located behind the motor 40 and above the air inlet 122. The lower housing 12 is substantially a plane parallel to the ground, and the bottom of the motor inlet 42 is defined by the surface of the lower housing 12 to reduce the height of the air duct.

The dust cup 20 is provided with a cyclone chamber, a cyclone 22 disposed in the cyclone chamber, a dust collecting chamber surrounding the outside of the cyclone chamber, and a dust cup outlet 220 located below the cyclone 22. The dust cup air outlet 220 is located above the air inlet duct 32, the air inlet duct 32 is located below the dust cup 20 and moves along the bottom surface of the lower machine body 12, the air inlet of the dust cup 20 and the dust cup air outlet 220 are both arranged at the bottom of the dust cup and are communicated with the lower machine body 12, bending is reduced, the length of the air duct is shortened, and noise is reduced.

The motor 40 is vertically placed, and the motor air inlet 42 is located below, i.e. vertically from top to bottom, and is installed in the motor cavity of the lower body 12, while the impeller cover of the motor 40 is located at the bottom, and the rotor assembly is located above the impeller cover. The air outlet duct 54 is bent and extended along the motor cover 50 from the air outlet 52 located at one side of the motor cover, bent and bent into the other side of the motor cover 50, and is exhausted from the air outlet 124. The outlet air duct 54 is located above the inlet air duct 32, and the outlet air duct 54 is preferably located above the outlet air 124. From this realize that the wind channel is extended by front end to rear end direction, and from up extension down, be very different with wind channel structure in the past to have better noise reduction.

The invention has simple structure, simplifies the air inlet duct, shortens the length of the air inlet duct and reduces the noise of the dust collector motor.

It should be understood that the above-mentioned embodiments are only illustrative of the technical concepts and features of the present invention, and are intended to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention. All equivalent changes or modifications made according to the spirit of the main technical scheme of the invention are covered in the protection scope of the invention.
