Description

An air duct structure applied to a vacuum cleaner

technical field

The invention relates to an air duct structure applied to a vacuum cleaner.

Background technique

As we all know, the working principle of the cyclone vacuum cleaner is as follows: the motor of the vacuum cleaner rotates at a high speed, sucking in air from the suction port, so that a certain vacuum is generated in the dust cup, and the airflow with dust enters through the ground brush, connecting pipe, handle, hose, main suction pipe and other accessories in turn. In the dust cup, the cyclone chamber in the dust cup makes the air flow rotate at high speed and generates strong centrifugal force, which drives the dust to rotate and deposit. The separated dust is quickly dropped into the dust collection chamber, and the filtered air enters the motor through the filter. , the air entering the motor flows out through the motor, and is filtered by the filter device after the motor before being discharged into the atmosphere. However, the air duct structure of the existing cyclone vacuum cleaner is complicated, and the length of the air duct is long, resulting in limited noise reduction effect.

Contents of the invention

The object of the present invention is to provide an air duct structure applied to a vacuum cleaner.

A technical solution of the present invention is: an air duct structure applied to a vacuum cleaner, which includes a body, a motor cover located in the body and an air outlet duct, the air outlet duct is formed along the air outlet on one side of the motor cover Bend and extend the motor cover, and then bend into the other side of the motor cover.

On the basis of this technical solution, it further includes the following subsidiary technical solutions:

The motor is placed vertically, and the air inlet of the motor is located below.

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

Another technical solution of the present invention is: an air duct structure applied to a vacuum cleaner, which is characterized in that it includes: a body, a motor cover located in the body, an air inlet duct located under the motor cover, and a structure surrounding the motor cover. The air outlet air channel is bent and extended and located above the air inlet air channel.

The invention has the advantages of simple structure, simplification of the air intake duct, shortening the length of the air intake duct, and reducing the motor noise of the vacuum cleaner.

detailed description

Embodiment: As shown in Figure 1-2, the present invention provides a specific embodiment of the air duct structure applied to the vacuum cleaner, the vacuum cleaner includes a lower body 12, an upper body 14 buckled with the lower body 12, a movable The dust cup 20 that is arranged between the upper and lower bodies 14,12, the filter device 30 located below the dust cup 20, the air inlet duct 32 located below the filter device 30, the dust cups that are accommodated in the upper and lower bodies 14,12 The motor 40 , the motor cover 50 containing the motor 40 and having the motor air outlet 52 , and the air outlet duct 54 connected with the air outlet 52 . The upper and lower bodies 14, 12 jointly form the body, and have a receiving cavity for accommodating the dust cup 20 and partially opening outwards.

The lower body 12 includes a housing chamber 120 corresponding to the dust cup 20 and housing the filter device 30 , an air inlet 122 located in front of the housing chamber 120 , and an air outlet 124 located behind the motor 40 and above the air inlet 122 . The lower body 12 is roughly a plane parallel to the ground, and the bottom of the motor air inlet 42 is bounded by the surface of the lower body 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 collection chamber surrounding 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, and the air inlet duct 32 is located below the dust cup 20 and runs against the bottom surface of the lower body 12. The air inlet of the dust cup 20 and the dust cup outlet 220 are all provided. At its bottom, it communicates with the lower body 12 to reduce bending to shorten the length of the air duct and reduce noise.

The motor 40 is placed vertically, and the motor air inlet 42 is located below, that is, it is installed in the motor chamber of the lower body 12 vertically from top to bottom, and 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 bends and extends along the motor cover 50 from the air outlet 52 located on one side of the motor cover, and then bends into the other side of the motor cover 50 , and the air is discharged from the air outlet 124 . The air outlet channel 54 is located above the air inlet channel 32 , and the air outlet channel 54 is preferably located above the air outlet 124 . In this way, the air duct extends from the front end to the rear end, and extends from the bottom to the top, which is quite different from the previous air duct structure, and has a better noise reduction effect.

The invention has a simple structure, simplifies the air intake duct, shortens the length of the air intake duct, and reduces the motor noise of the vacuum cleaner.

Of course, the above-mentioned embodiments are only to illustrate the technical conception and characteristics of the present invention, and its purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and not to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit of the main technical solutions of the present invention shall fall within the protection scope of the present invention.
