The link will detail made to the exemplary embodiment of the present invention, illustrated in the drawings, in which identical reference position are identical to the elements.

As shown in the drawings, the device speed control suction flow includes a first channel 100 suction flow, the second channel 200 intake flow and the device 300 for opening/closing (see figa, 3B, 4 and 7).

The first channel 100 suction flow is formed in the coupling device H with a flow channel (see figure 1). One end of the coupling device H with a flow channel connected with the main body of the vacuum cleaner 1 (see Fig), and the other end is connected to node 2 brushes. The air containing the pollutant particles are absorbed in the node 2 brushes through the first channel 100 intake flow passes into the main body 1 of the vacuum cleaner.

The second channel 200 sasivimol the thread formed in the arm 3, located on the coupling device H with the flow channel, and includes a first hole 210 and the second hole 220 (see Fig.7).

The first hole 210 is connected by fluid from the outer side of the arm 3, and sucks air through the second channel 200 suction flow. As illustrated in figure 2, the first hole 210 on the rear side of the arm 3 is specified position and is made in the form of a grid.

The second hole 220 is formed inside the arm 3 and is connected by fluid from the first channel 100 suction flow. The second hole 220 selectively opening/closing device 300 for opening/closing (see figa, 3B and 4) and includes an exhaust grille 221 and the first sound-absorbing device 222. Exhaust grille 221 (see Fig.7) contains many holes. The first sound-absorbing device 222 is located on the upper part of the exhaust grille 221 and prevents the passage of contaminants, as well as filtering pollutants from the air that passes through the first channel 100 intake stream.

The device 300 for opening/closing selectively opens or closes the second hole 220, and moves the intake air through the first hole 210, the first channel 100 suction flow through the second hole 220.

The device 300 for opening/closing includes Colisee device 310 and the handle 320 of the control. The moving device 310 slides along with the movement of the handle 320 controls and regulates the flow area of the second openings 220. The amount of air passing through the second hole 220 is determined in accordance with the location of the moving device 310. The moving device 310 is installed in the form of a groove 311 with an open top, as illustrated in figa and 3B. The air that passes through the first hole 210 is moved into the second hole 220 through the slot 311.

The handle 320 management is open on the outer side of the arm 3 and is connected with a sliding device 310. Therefore, if the user moves the handle 320 control the moving device 310 is moved together with the moving handle.

As shown in figure 5 and 6, the display device 4, which shows the strength of the suction, is located on the opposite side of the arm 3 relative to the handle 320 of the control. The control device 4 indicates the strength of the suction, which can be "strong", "medium" or "weak" in accordance with the location of the handle 320 of the control. The handle 320 of the control consists of a transparent window so that the user can conveniently check the information of the display device 4.

As shown in Fig.7, at least one second sound-absorbing device 230 is installed between the first opening 210 and the second is a hole 220 in the second channel 200 suction flow. The second sound-absorbing device 230 is installed to reduce the speed of intake air from the outside, and contains the set of edges, protruding vertically into the air, which enters through the first opening 210.

As shown in Fig, the vacuum cleaner according to the present invention includes the main body 1, the node 2 brushes and a coupling device H with a flow channel that has the arm 3. Node 2 brushes connected to the coupling device H with a flow channel with a sliding tube 5, and a connecting device with a flow channel connected with the main body 1 through a flexible sleeve 6. Since no separate control device or switching device does not need to control the suction power of node 2 brushes, do not need to place a separate electrical wires in the flexible sleeve 6.

Operation speed control suction flow of the present invention will be explained with reference to Fig.7 and 8.

When turning on the vacuum cleaner, the air containing the pollutant particles are absorbed through the node 2 brushes, passes through the sliding tube 5 and the first channel 100 suction flow in the coupling device H with a flow channel for feeding in the main body 1.

If the user wants to reduce the suction power of node 2 brushes by reducing the speed of flow is ozdoba, containing pollutant particles, the user moves the handle 320 of the control in the direction of the arrow shown in Fig.7, and opens the second hole 220. Air from outside is sucked into the first opening 210 under the action of the suction pressure generated by the suction motor (not shown) in main body 1. The intake air from the outside passes in the first flow channel 100 through the second hole 220, thus reducing the flow rate of air containing particles, which is absorbed via the node 2 brushes. Therefore, reduced suction power.

The first sound-absorbing device 222 in the second hole 220 is made of a porous material such as sponge, and reduces the noise that can occur when the intake air from the first hole 210, passes through the grid 221, and it also prevents the passage of contaminants through the first hole 210.

The second sound-absorbing device 223 includes many ribs located between the first opening 210 and the second opening 220, and reduces the flow rate of air which passes through the first hole 210 in the second channel 200 flow, and thus reduces the noise that can result from friction of the air, when the air from outside is sucked through the second CTE is rtie 220.

In accordance with the exemplary embodiment of the present invention, the flow rate of intake air through the node 2 brushes, can be adjusted without control the speed of the suction motor, simplifying the design of the vacuum cleaner. In particular, since the electric wires are not required for connecting flexible hose 6 and the arm 3 with the main body 1 of the vacuum cleaner, piece price of manufacture can be reduced, the number of electronic components can be minimized, and the inconvenience of the user associated with faulty elements, also can be minimized.
