Description

[0001] The present invention relates to a dust brush for reflux vacuum cleaner,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a brush structure detachably attached to a suction head of a vacuum cleaner, and more particularly, to a vacuum cleaner using an intake air and an exhaust, The present invention relates to a brush structure capable of effectively removing dust from an object to be cleaned or a subject by using a method of sucking dust and air at the same time.

BACKGROUND ART [0002] Generally, a vacuum cleaner is roughly divided into a suction head portion for sucking foreign matter by attaching an appropriate brush to a cleaning place or an object, and a main body portion having an inlet port and an exhaust port and generating a suction force of the suction head .

The main body portion is provided with a suction pump for generating a suction force again, a filter device connected to the suction pump for blocking foreign substances sucked together with the air through the suction port from the suction head, and an exhaust port for discharging the air from which foreign substances have been removed to the outside of the main body do.

The reflux vacuum cleaner circulates all or a part of the air discharged through the exhaust port of the general vacuum cleaner to the suction head and discharges the cleaned air from the brush of the suction head. Or a method in which foreign substances of a subject are levitated and the brush is again sucked in the floating foreign matter.

In the case of a brush which is detached from a suction head of a vacuum cleaner, various structures and purpose brushes are provided so that the user can use an appropriate brush depending on the place to be cleaned or the object to be cleaned.

However, brushes suitable for cleaning places or objects such as showcases, bookcases, dressers, desks, cabinets, etc., where relatively light objects are arranged in an unfixed state, have not yet been provided.

The most effective way to remove dusts from the above-mentioned cleaning places or objects is to use a dust separator that removes dust by using static electricity of hair made of many soft animal hair or artificial synthetic materials.

However, the way to remove dust using a conventional dust separator is to periodically and frequently remove the dust from the outside of the dust separator.

If it does not, it has the disadvantage that it removes the dirt from the above-mentioned cleaning place or object, and removes it temporarily in the air, and then sinks to the same place or object again after a certain time.

Accordingly, there is a need to develop a dust separating brush for a vacuum cleaner that can lift dust from a cleaning place or an object requiring removal of the dust, and that can remove dust by being sucked by a vacuum cleaner.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a dust separating brush for a vacuum cleaner which can remove dust from a cleaning place or a target where a conventional brush for a vacuum cleaner can not effectively remove dust.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a dust separating brush of an exhaust reflux type vacuum cleaner according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a view showing a conventional vacuum cleaner of an exhaust gas recirculation type and a conventional brush mounted on a suction head. The principle of operation of the vacuum cleaner of the exhaust gas recirculation type is described.

As shown in FIG. 1, the conventional vacuum cleaner of the reflux type has a suction head 102, a suction port 103 and an exhaust port 104, to which foreign matter is sucked, A main body 105 of the vacuum cleaner includes a main body 105 having a suction pump 106 for generating a suction force and a suction pump 106 connected to the suction pump 106, And a discharge port 108 for discharging the air from which the foreign substances have been removed to the outside of the suction pump 106 chamber.

Further, a reflux passage 109 for refluxing all or a part of the air discharged to the outside of the suction pump 106 through the discharge port 104 to the suction head, and circulating air to the brush through the discharge port 104 And an intake passage 111 for transferring the air sucked together with foreign matter from the brush to the intake port 103 of the main body 105. [

The air flow of the conventional vacuum cleaner of the exhaust gas recirculation type is indicated by an arrow.

1, the principle of an exhaust gas recirculation type vacuum cleaner is that the air circulated through the discharge port 108 of the suction pump chamber 106 of the main body 105 is supplied to the brush 101 through the suction head 102 The foreign substances 113 existing on the surface to be cleaned 112 in the brush are lifted by the pressure of the air discharged from the brush and the foreign substances 113 are sucked through the suction port 114 of the brush .

By doing so, the exhaust gas recirculation type vacuum cleaner can easily suck foreign matter 113, which is firmly attached to the surface to be cleaned 112 or difficult to be sucked only by the suction force of the vacuum cleaner, Conventional vacuum cleaners do not require special brushes, such as rotating brushes, used to improve cleaning efficiency.

FIG. 2 illustrates conventional brushes provided by a conventional vacuum cleaner, and an appropriate brush is mounted on a suction head according to a place to be cleaned or a subject.

As shown in FIG. 2, the brush 201 of the first structure is generally used most frequently as a brush, which removes foreign matters in a cleaning place or an object having a flat, uniform, large area such as a floor of a bedroom or a living room And the brush 202 of the second structure is used in a non-flat, uneven, but relatively wide cleaning area or object, such as a sofa or bed.

The bristles 203 of the third structure are used for the purpose of removing foreign matters on the hairy surface such as carpet. The bristles 204 of the fourth structure are used for the purpose of removing foreign matters in the narrow and deep grooves as the window frames, The brush 205 of the fifth structure is used for the purpose of removing a small area of foreign matter having a complicated structure that is not flat, such as household appliances, furniture, or frames.

In addition to the structures shown in FIG. 2, there are various structures, but the structures are slightly modified based on the brushes of the first to fifth structures and purposes.

Although it is necessary to remove dust such as a display case, a bookcase, a dresser, a desk, and a cabinet in a general cleaning process, it is not easy to remove dust with a vacuum cleaner using various conventional brushes shown in FIG.

Since the places to be cleaned or objects to be cleaned as described above are places where relatively light objects are not fixed and the shape to remove dust is uneven and complicated, it is preferable to use brushes 202 and 205 provided with hair.

However, since the conventional brushes 202 and 205 of the second or fifth structure are provided with short lengths made of a hard material, if dust is removed by the brushes 202 and 205, Things will get messy.

Therefore, although a brush having a very long and smooth brush is suitable for the above-described cleaning places or objects, if the brush of a general vacuum cleaner has long and soft brushes as shown in FIG. 3, 301 are sucked into the suction port 302 of the brush, they can not play the roles of the moths at all and it is difficult to operate properly with a brush for a vacuum cleaner.

Accordingly, the above-described methods for effectively removing dust or dirt from a cleaning place or an object are to use a conventional dust separator that is made of soft animal hair or synthetic material and removes dust using static electricity.

However, the way to remove dust using a conventional dust separator is to frequently remove the dust from the outside of the dust separator, or to remove the dust from the above listed cleaning area or target Is floated up into the air, and the dust only sinks again after a certain period of time.

Therefore, in general, in the cleaning process, the above-described cleaning of the cleaning place or the object is performed by removing all of the placed objects, wiping the dust on the surface of the object to be cleaned or the object to be cleaned with the wet cloth, It is done in a way that it is originally arranged.

This is a very inefficient method compared to the time and effort of cleaning with a vacuum cleaner. The vacuum cleaner dust which floats only the dust without moving the objects placed in the above-mentioned cleaning place or the object and the floating dust is sucked into the vacuum cleaner It is necessary to develop a brush.

FIG. 4 shows the overall shape of a dust separating brush according to the present invention and a shape mounted on a suction head of a conventional exhaust gas recirculation type vacuum cleaner. The main body of the exhaust gas recirculation type vacuum cleaner and the suction head are the same as those of the conventional apparatus , It is not necessary to provide the suction head with a special component or device for detachment of the duster brush according to the present invention.

4, the dust separating brush according to the present invention includes a plurality of tube-shaped exhaust wicks 501 made of a soft material, an intake wool 503, a plurality of exhaust wool 501, A connecting rod 601 for connecting the first and second passageways 503 to each other through two independent passageways, a rigid rod-shaped handle 701 including the two passageways separately, A long extension line 801 made of a soft material so as to freely move the exhaust wrist 501 and the intake wrist 503 and a coupling part 901 connected to the suction head 401 part.

Hereinafter, with reference to FIGS. 5 to 9, the components of the dust removing brush according to the present invention shown in FIG. 4 have been described in detail.

FIG. 5 is a detailed view illustrating the structure of the exhaust cam and the intake cam of the dust separating brush according to the present invention.

As described above, the exhaust wrestler 501 is made of an artificial synthetic material of a very soft material so that no physical force is applied to the objects to be disposed in a place or object to be cleaned in which other objects that are not fixed are disposed, and irregularly cleaned So that the air can be discharged through the inner passage as the structure of the hollow tube 502 having the inside thereof.

To simplify the structure of the exhaust wrestling 501, it can be considered that the general electrostatic dust collecting wicks are in the shape of an empty tube.

The air intake port 503 also has a structure of an inner tubular shape 502 and allows the air to be sucked through the inner passage. The intake port 503 is also connected to the cleaned place or the target And is made of a soft material to some extent so that no physical force is applied to the placed objects, but when the physical force is not applied, the intake wrist 503 is made of a rigid material such that the linear shape is maintained.

Unlike the exhaust wrestler 501, the intake wrestler 503 is not a portion to be directly contacted with the above-described cleaning place or the object, but rather is in contact with the air to be cleaned or air And has a length shorter than that of the exhaust wrestling 501 because it plays a role of sucking up dust that has been floated in.

In addition, since the dust separator using the conventional static electricity is a method of attaching dust to the dust collectors, it is necessary to have a very large number of dust collectors. However, since the dust separator brush according to the present invention absorbs and removes dust with a vacuum cleaner, Fewer than two dogs are provided.

However, since a dust removing brush having too few exhaust wicks (501) or suction wicks (503) requires a lot of repetitive operations to remove dust from the above-mentioned cleaning places or objects, A proper number of exhaust wicks 501 and a smaller number of intake wicks 503 are required.

FIG. 6 is a detailed view illustrating a structure of a connection portion of a dust separating brush according to the present invention.

The connecting portion 601 of the dust separating brush according to the present invention includes a short cylindrical upper structure 603 and a plurality of suction motions 503 which are connected to a single exhaust passage 602 by connecting a plurality of exhaust wicks 501, Shaped lower structure 605 which connects the intake passage 604 and the intake passage 604 to one intake passage 604.

The upper structure 603 and the lower structure 605 are in contact with each other and the structure 603 is brought into contact with the exhaust wrestling 501 and the intake wresting 503, And is connected to one knob 701.

7 is a detailed view of the structure of the handle of the dust-removing brush according to the present invention.

The handle 701 is a rigid rod structure having no special structure or device and including a non-slip surface 702. The handle 701 can move a large number of moats freely, similar to the handle of a conventional electrostatic dust separator. It is the role of

However, due to the characteristics of the dust separating brush according to the present invention, the exhaust passage 602 and the intake passage 604 of the connecting portion shown in FIG. 6 extend from the inside of the handle 701 and are independently included.

8 is a detailed view illustrating the structure of extension lines of the dust removing brush according to the present invention.

The extension line 801 is an extension line including the exhaust passage 602 and the intake passage 604 included in the handle 701 shown in Fig. 7, and is a line extending from the main body 105 of the vacuum cleaner, So that the handle 701 can be freely moved by gripping the handle 701. In addition,

FIG. 9 is a detailed view of the structure of the engaging portion of the dust removing brush according to the present invention.

One end 902 of the coupling portion 901 is connected to the extension line 801 shown in Figure 8 and the other end 903 is connected to the suction head 102 of the vacuum cleaner of the exhaust gas recirculation type, 904b separated from one end 902 connected to the intake passage 602 and the other end 903 connected to the intake passage 604. [

The other end 903 of the engaging portion 901 should be constructed so as to be capable of being accurately detached from the suction head of an exhaust reflux vacuum cleaner providing the brush and also provided with a mechanism 905 for engaging .

The separate tubes 904a and 904b of the coupling portion 901 are connected to the exhaust passage 110 and the intake passage 111 in the suction head of the conventional vacuum cleaner of the exhaust gas recirculation type, The exhaust path and the intake path connected to the rear-end vacuum cleaner main body 105 are completed and the circulation path of the entire air is completed.

Therefore, the entire air circulation path is branched from the discharge port 108 of the vacuum cleaner main body through the reflux passage 109, the exhaust pipe 104, the exhaust passage 110 of the suction head, the pipe 904b of the coupling portion, Air is exhausted through the exhaust passage 602 of the handle, the upper structure 603 of the connecting portion and the exhaust port 501. The exhausted air together with the dust forms the intake port 503, the lower structure 605 of the connection portion, The intake passage 604 of the handle, the intake passage 604 of the extension line, the pipe 904a of the coupling portion, the intake passage 111 of the intake head, the intake pipe 103, the filter device 107, And discharged to the discharge port 108 of the main body of the vacuum cleaner.

The most distinctive feature of the dust separating brush according to the present invention is that the air is injected into and discharged from the exhaust port of the dust separating brush along the above-described air circulation path to have a force always directed to the outside.

By doing so, as shown in FIG. 3, it is possible to eliminate the phenomenon that the hair is sucked into the suction port of the brush by the suction force of the vacuum cleaner brush.

For example, a sky dancer, a balloon doll often used at events like opening ceremonies, is the same principle that keeps going to the sky because the air is blowing inside the doll.

In addition, since it is intended to remove light dust adhering to the above-described cleaning places or objects, the intake air shutter 503 may have only a suction force enough to absorb dust, and exhaust air that is stronger than the suction force may be supplied to the exhaust air outlet 501 It is possible to solve the problem of the existing brush shown in Fig. 3 more effectively.

In addition, since a general dust separator uses static electricity, physical contact with a dusty cleaning place or an object is absolutely necessary. However, the dust separating brush according to the present invention is not limited to the physical contact of the exhaust wool 501, ), The dust or the object to be cleaned is lifted by the air discharged from the air outlet 503, and the floated dust is sucked through the air intake port 503, so that the degree of dust removal is much higher than that of the conventional electrostatic dust separator Becomes excellent.

In addition, since the inhaled dust collects in the dustbin of the vacuum cleaner, it is not necessary to drop the dust outdoors like the conventional electrostatic dust separator.

FIG. 10 is a schematic view of the dust removing brush according to the present invention for removing dust accumulated on a dressing table, and dust can be removed by the same principle as that of the above-mentioned other places or objects to be cleaned.

A plurality of soft exhaust pores 501 are passed between the comparatively light various objects 1002a, 1002b and 1002c disposed on the dressing table 1001 and passing through the physical contact and air 1004 discharged from the exhaust port 501 The dust 1005 accumulated on the surface of the objects 1002a, 1002b, and 1003c as well as on the dressing table 1001 floats up into the air.

These floating dusts 1005 are sucked through the intake port 503 and collected in the dust container of the vacuum cleaner of the exhaust gas recirculation type.

The core principle of the dust separating brush according to the present invention is a brush suitable for an exhaust reflux type vacuum cleaner since air is injected into and discharged from the brush of the brush.

However, even a conventional suction type vacuum cleaner may be provided with a device or structure capable of supplying air separately to the main body of the vacuum cleaner, and the extension line 801 and the engagement portion 901 of the dust separating brush are suitably modified The dust separating brush according to the present invention may be used.

The material or the shape of the handle 701 or the extension line 801 constituting the dust separating brush according to the present invention may be modified using different materials for the convenience of cleaning and design of the entire vacuum cleaner, .

The dust separating brush according to the present invention is directly connected to the main body 105 of the vacuum cleaner and not the suction head 102 of the vacuum cleaner of the exhaust gas recirculation type vacuum cleaner so that the separated pipes 904a, 904b are directly connected to the exhaust pipe 104 and the intake pipe 103 of the main body, the same effect as described above can be obtained.

Lastly, the structure of the exhaust wick and the intake air simulator applied to the dust separating brush according to the present invention is an example of a straight shape, and it is possible to use a structure having one or more branches for cleaning effect and efficient air discharge, It can also be in the form of.

The present invention has been described with reference to the preferred embodiments. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense. The scope of the present invention is defined by the appended claims rather than by the foregoing description, and all differences within the scope of equivalents thereof should be construed as being included in the present invention.
