Description

Dust cup structure with built-in air duct

technical field

The invention relates to a dust cup structure with a built-in air duct.

Background technique

At present, most of the air ducts in upright vacuum cleaners are set on the body, so that an air duct needs to be protruded on the whole machine, which increases the space of the whole machine, increases the packaging space, and the shape of the whole machine is not conducive to making Streamlined, while the air duct is set outside the machine, the length of the air duct will also increase, and the loss of air volume will increase.

Contents of the invention

The purpose of the present invention is to provide a dust cup structure with a built-in air duct, so as to simplify the structure, reduce the space of the whole machine, shorten the length of the air duct, and reduce the loss of air volume.

The first technical solution of the present invention is: a dust cup structure with a built-in air duct, the air duct is located inside the cup body and integrally formed with the cup body.

On the basis of the first technical solution, the following subsidiary technical solutions are further included:

The air inlet of the air duct is located at the bottom of the cup body.

It also includes a cyclone cone which is integrally detachable and located downstream of the air duct.

The second technical solution of the present invention is: a dust cup structure with a built-in air duct, which includes: a cup body with an inner cavity, an air duct integrally formed with the cup body, a cyclone arranged in the inner cavity, a cyclone arranged in the cyclone The cyclone cone in the filter, the filter element located downstream of the cyclone cone, and the cup cover that shields the filter element.

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

The cyclone and the hollow interior of the cyclone cone together form a detachable cyclone assembly.

The cup body includes an ash collection chamber at the bottom of the inner cavity, a first rib on the inner wall of the cup, and a second rib on the inner wall of the cup, wherein the first and second ribs extend in the longitudinal direction of the cup body, and the second rib The length of the first rib is greater than the length of the second rib.

The air duct includes an air inlet, an air outlet, and a guide part adjacent to the air inlet and changing the direction of the airflow.

The air inlet is located at the bottom center of the cup body, while the air outlet is located at one side of the cup body, and the extending direction of the guide part intersects with the longitudinal direction of the cup body to form an acute angle, while the bottom of the second retaining rib is arranged on the guide part and below the bottom of the cyclone.

Advantage of the present invention is:

The invention realizes the complete separation of dust and gas, shortens the length of the air duct of the whole machine, reduces the loss of air volume, and because the air duct is inside the dust cup, the shape of the body will not be affected, and the streamlined shape can be fully considered At the same time, the air duct and the cup body are designed in one piece. The user can directly take out the entire cyclone assembly from the dust cup. It is convenient to clean the cyclone assembly and pour ash from the dust cup.

Detailed ways

Embodiment: As shown in Figure 1-2, the present invention provides a specific embodiment of a dust cup structure with a built-in air duct, which includes a cup body 10 with an inner cavity 12, and an air duct 14 integrally formed with the cup body 10 , the cyclone 20 arranged in the inner cavity 12 , the cyclone cone 30 arranged in the cyclone 20 , the filter element 40 located downstream of the cyclone cone 30 , and the cup cover 50 for shielding the filter element 40 . The cup lid 50 is provided with an outlet 52 for guiding air flow out. The filter element 40 is preferably a soft rubber sponge. The cyclone 20 and the cyclone cone 30 are hollow inside to form a detachable cyclone assembly. The cup cover 50 is rotatable and detachable, which is convenient for users to operate and replace the filter element 40 .

The cup body 10 includes a dust collection chamber 120 at the bottom of the inner cavity 12 , a first rib 122 at the inner wall of the cup body 10 , and a second rib 124 at the inner wall of the cup body 10 . Wherein the first and second ribs 122 , 124 extend in the longitudinal direction of the cup body, and the length of the first rib 122 is greater than the length of the second rib 124 .

The air duct 14 generally extends along the longitudinal direction of the cup body 10 , and includes an air inlet 140 , an air outlet 144 , and a guide portion 142 adjacent to the air inlet 140 and changing the direction of the airflow. The air inlet 140 is located at the center of the bottom of the cup body 10 , while the air outlet 144 is located at the higher side of the cup body 10 , and the guide portion 142 promotes the airflow from the center to the outside and upwards. The extension direction of the guide part 142 intersects with the longitudinal direction of the cup body 10 to form an acute angle, and makes the upper cross-sectional area of the inner cavity 12 large, while the lower cross-sectional area is small, and the bottom of the second retaining rib 124 is arranged on the guide part 142. This accelerates the rapid fall of the dust and prevents the dust from being raised again. In addition, the top of the second rib 124 is slightly lower than the bottom of the cyclone 20 . The top of the first rib 122 is higher than the bottom of the cyclone 20 .

The cyclone 20 is a hollow cylinder and communicates with the inner cavity 12 through the ash throwing port 22 .

The cyclone cone 30 has several meshes, and a cyclone channel that guides airflow into the interior of the cyclone 20 and communicates with the air outlet 144 of the air channel 14 .

When working, the airflow with dust enters the dust cup from the air inlet 140 at the bottom of the cup body, changes direction through the guide part 142 and smoothly flows out from the air outlet 144 into the cyclone channel, and throws dust through the helical surface of the cyclone channel. The dust moves downward in a spiral shape along the side wall of the inner cavity of the cyclone 20, and falls into the ash collection chamber 120 from the ash throwing port 22, and part of the fine ash gas enters the filter element 40 through the mesh of the cyclone cone 30, and is filtered. Sponge filter of part 40, clean air enters the motor from the outlet 52 of the cup cover 50, so that the complete separation of dust and gas is realized, the length of the air duct of the whole machine is shortened, and the loss of air volume is reduced, and because the air duct is in the Inside the dust cup, the shape of the body will not be affected, and the streamlined design can be fully considered. At the same time, the air duct and the cup body are designed in one piece. The user can directly take out the entire cyclone assembly from the dust cup, and it is convenient to clean the cyclone assembly. The dust cup is convenient for pouring ash.

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.
