WO2014120109A1 - Vibrating vacuum cleaner attachment - Google Patents

Abstract

The invention relates to vacuum cleaners and specifically to vacuum cleaner attachments. A method is carried out by means of using a vacuum cleaner attachment body having an internal flow of air, an impeller shaft, and a weighted impeller which is mounted on the shaft within the body and which generates directed centrifugal vibrations during rotation. The weighted impeller is rotated by the flow of air, generating directed centrifugal vibrations which are transferred from the impeller to the attachment body via the shaft on which the impeller is mounted. The directed vibrations generated by the impeller are transferred to the attachment body and to a cleaning brush, and said cleaning brush strikes resonantly, thoroughly beating the surface being cleaned. The invention allows for significantly increasing the quality of cleaning of any surface. The method can be applied to a variety of vacuum cleaner attachment models and designs.

Description

 A method of creating vibration nozzles for a vacuum cleaner. Vibration nozzle for a vacuum cleaner.

The field of technology.

 The invention relates to vacuum cleaners, namely nozzles for vacuum cleaners.

Known nozzle designs: US 2012 0227211; KR 2007 0109390;

 US 6122798; US 2159164

 In all these nozzles, vibration is created on individual moving parts that are inside the nozzle bodies and transmitted to a surface that is cleaned through moving parts inside the bodies.

 All of the above nozzles are designed for cleaning, some of them have devices for mechanical impact on dust, or devices that generate vibrations, but none of them are perfect and after cleaning leaves some dust that can not be removed.

A big drawback of these nozzles and turbo brushes is the loss of power due to losses on overcoming the friction forces of many moving parts, this leads to low cleaning efficiency.

The closest prior art is the nozzle application - UA 2011 04156.

 In the description of the application, the author suggests creating uniform vibrations with the nozzle on the brush of the vacuum cleaner, the brush should bounce over

surface, and then sink to the surface - due to which, according to the inventor, the effect should be achieved.

To create vibrations, the author proposes to use an impeller with a sinker located on one of the impeller wings.

During rotation, such an impeller with a sinker creates uniform centrifugal vibrations, which are then transmitted to the housing.

Such a design is not perfect and the way vibrations are created does not give a sufficient effect to obtain a result.

SUBSTITUTE SHEET (RULE 26) Thus, the technical task of the invention is to create a nozzle for a vacuum cleaner, which will qualitatively knock out, shake out the surface, which is cleaned by creating directed vibrations of the nozzle itself to the side

surface that is being cleaned.

The technical result is achieved due to a fundamentally new method of mechanical impact on dust, namely the creation of directed vibrations of the nozzle itself, in which the impeller is used to form directed centrifugal vibrations due to the use of an uneven surface on the impeller

interacting with air, and the transmission of these vibrations to the nozzle body through the axis on which the impeller is mounted.

The technical result is also achieved due to the fact that the axis on which the impeller is mounted is installed in the housing and in

the impeller is free with a gap X, with the possibility of rolling the axis along the walls of the device and relative to the housing (Fig. 3), for

reduce friction on the axis during operation of the nozzle.

A general view of the best execution of the method shown in the example

the design of the nozzle and the vibrating device are shown in FIG. 1 and FIG. 2.

 The nozzle for a vacuum cleaner with an impeller for creating vibrations consists of: a housing 3, which can be made of plastic, inside of which there is an impeller 4, a sinker 5 and an axis 8 which, during rotation, creates directional vibrations.

In the impeller, a sinker 5 is built in between the two wings.

 When rotating the impeller with a sinker, rolling along axis 8 creates significant directed centrifugal vibrations.

The impeller itself is installed with a diametrical clearance XI on axis 8, with the possibility of free rolling along the axis during rotation. The axis 8 is contained in the holes created by the housing 3 and the cover 9 also with

SUBSTITUTE SHEET (RULE 26) diametral clearance X2, with the possibility of free

rolling in holes when the impeller rotates.

The cover relative to the housing can be fixed on four special locks 10 (figure 2), 2 on each side of the cover and their corresponding locks on the nozzle body.

Thus, the impeller for creating directed vibrations in the example in the figures is mounted on axis 8 so that when the device rotates, the device rolls along axis 8 and axis 8 rolls along case 3 and nozzle cover 9 in the hole that they form in which the axis is installed .

 As a result of this solution, the friction forces during the rotation of the impeller are practically absent, therefore, the maximum effect of vibrations is achieved but no power is lost.

 To create directional vibrations, the impeller has a part of the radial volume 11 filled with plastic with a sinker 5 and on the outer part of the filled volume has accelerating ribs 2. Or it can have any surface structurally unequal with respect to other surfaces of the impeller interacting with the air stream 1.

 Due to this, the impeller creates uneven - directed vibrations at the moment of interaction of the air flow with such

unequal surface, in this example with accelerating ribs on the surface of the impeller.

 According to the design, shock vibration is created in the direction of the surface, which is cleaned.

The method of creating vibrations of the nozzle presented in the example in the figures works as follows:

When the vacuum cleaner is working, the impeller to create directional

vibrations due to the impact of air flows in the nozzle - it rotates and rolls around on axis 8 and untwists axis 8 itself, which rolls around the inner diameter of the hole created by the housing 3 and the nozzle cover 9, at the moment of the interaction of the directed air flow and the accelerating ribs, the impeller creates significant directional vibrations that are transmitted through axis 8 to the housing

SUBSTITUTE SHEET (RULE 26) nozzles 3, and the cover 9, and are transmitted further through the body of the nozzle 3 to the brush 12 (Fig.Z).

During operation of the vacuum cleaner, the impeller for creating directed vibrations 4 rotates from the action of directed air flows on it.

 The technical result is achieved due to the action of force

directed air flows to the filled radial volume b, and accelerating ribs placed on it - 2. From this interaction, the impeller is instantly accelerated and creates directional vibrations that are transmitted through the axis 8 to the nozzle and through the housing 3 to the brush 12 (Fig. 3).

 Due to the directed vibrations created by the nozzle, the brush strikes the surface and shakes the surface, which is cleaned.

Thus, during the operation of the nozzle, high-quality knocking out occurs, dust is shaken out by the brush itself - which leads to better cleaning.

The design of the nozzle at the suction end provides

installing a brush, or other nozzle for a vacuum cleaner.

Due to the directional vibration, any brush used with the nozzle is easy and moves on any surface.

Using a nozzle makes cleaning easy.

The invention can significantly improve the quality of cleaning of any surfaces.

The method of creating vibrations can be applied with any

various models and designs of nozzles for vacuum cleaners and has a low cost.
