Description

  The present invention relates to a suction tool that is attached to an electric vacuum cleaner main body or an extension pipe extending from the main body of the vacuum cleaner and cleans a surface to be cleaned.

  The suction tools that are attached to the vacuum cleaner are mainly used for cleaning large and flat surfaces to be cleaned, such as floor surfaces, and mainly for cleaning surfaces to be cleaned that have narrow spaces and irregularities. Some of them are relatively small. The former generally has a substantially T-shaped shape and a rotating brush mechanism, etc., and the latter generally has a simple structure having a shape corresponding to the application, and has a fixed brush body at the tip. There are many things. In particular, the latter is widely known to be used by being attached to a hand-held small vacuum cleaner for cleaning the interior of a car or a loading platform.

With respect to a relatively small suction tool having a fixed brush body at the tip, for example, a suction tool disclosed in Patent Documents 1 to 4 has been devised in various ways in the structure and properties of the brush body portion. However, these suction tools use a flocking brush as a brush body.

For this reason, if dust or the like is simply attached to the surface of the surface to be cleaned, it can be cleaned by removing the dust or the like with the tip of the flocking brush and sucking it with a vacuum cleaner. If the dust is entangled with the material joints, etc., the flocking brush may not be able to remove the dust sufficiently, and the vacuum cleaner itself may not be able to clean it effectively by suction .

  On the other hand, conventionally, so-called inclined pile fabric in which the tip of the brush hair is inclined has been used for clothes brushes. In the inclined pile fabric, short brush hairs inclined in a specific direction are formed at a high density on the surface of the fabric, and if the inclined pile fabric is rubbed against the surface to be cleaned in the direction in which the brush hairs are inclined, Since the tip of the ink enters the inside of the surface to be cleaned and scrapes out dust and the like, even when the material of the surface to be cleaned is a cloth, carpet or the like, the dust and the like can be easily and effectively removed.

The present invention has been made in view of the above problems, and its object is easily even if and when the material of the surface to be cleaned is cloth and carpets, etc., is further surface to be cleaned is a curved surface dust An object of the present invention is to provide a vacuum cleaner suction tool that can effectively remove the above and the like and has a simple structure.

In order to solve the above-mentioned problems, the invention according to claim 1 of the present invention is a vacuum cleaner suction tool comprising a dust collection portion and a suction pipe, wherein the dust collection portion has a central cavity and a thin plate shape. And a dust-collecting surface on the lower surface of the outer edge portion that is in contact with the surface to be cleaned is provided with a belt-like brush body made of an inclined pile fabric in which the tip of the brush hair on the surface of the fabric is inclined in the direction of the cavity. The outer edge portion is provided with one or a plurality of air intake portions in a blister shape in which a part of the outer edge portion is inflated upward so as to be able to inhale outside air into the cavity portion .

The invention of claim 2 is an electric vacuum cleaner suction tool comprising a dust collection unit and the suction pipe, the dust collection unit of the plurality of connecting the cavity and the cavity of the central radial It consists of a flexible thin plate-shaped outer edge portion provided with a cut, and the tip of the brush bristles on the fabric surface is inclined toward the cavity portion on the dust collecting surface of the lower surface of the outer edge portion in contact with the surface to be cleaned A belt-like brush body made of an inclined pile fabric is provided .

Furthermore, the invention according to claim 3 is characterized in that, in the vacuum cleaner suction tool according to any one of claim 1 or claim 2, the entire shape of the dust collecting portion is a disc shape. .

According to the electric vacuum cleaner suction tool according to the invention described in claim 1, and a strip-shaped brush body made of inclined pile fabric in dust collection surface in contact In the bottom of the dust collection unit to the surface to be cleaned Therefore, even when the material of the surface to be cleaned is cloth, carpet, etc., it is possible to easily remove dust and the like, an advantageous effect compared to a conventional vacuum cleaner suction tool using a flocking brush as a brush body Play.

  Further, since the belt-like brush body inclines the tip of the brush hair on the surface of the inclined pile fabric toward the inside of the dust collecting portion, the operator moves the suction tool for the vacuum cleaner in any direction. The tip of the bristles of the strip-shaped brush body arranged on the opposite side to the moving direction enters the interior of the surface to be cleaned and scrapes out dust and the like. As a result, the cleaning efficiency can be improved.

In addition, when the dust collecting surface that is the bottom of the dust collecting portion is in close contact with the surface to be cleaned, excessive vacuum is generated in the cavity due to the operation of a vacuum cleaner, and the dust collecting surface is becomes apt to adsorb to the surface to be cleaned, there is a risk of too load is applied to the motor or the electric vacuum cleaner lowers the work efficiency, the electric vacuum cleaner suction tool according to the present invention, the one on the outer edge Since one or a plurality of air intake portions that are blistered by inflating the portion upward are provided, outside air is appropriately sucked from the air intake portion into the cavity portion while the vacuum cleaner is operating. Thereby, an excessive negative pressure is not generated in the hollow portion, and an effect of preventing a reduction in work efficiency due to adsorption of the dust collection surface to the surface to be cleaned is achieved.

Furthermore, since the dust collecting part has an outer edge shape of a thin plate, even if there is an obstacle above the surface to be cleaned, to remove and suck the dust outside edge of the dust collecting unit pledged to slight gap It is possible to improve the efficiency of the cleaning work.

On the other hand, the vacuum cleaner suction tool according to the invention described in claim 2 is a flexible thin plate provided with a plurality of radial cuts that connect the outer edge of the dust collecting part to a central cavity. Therefore, the outer edge portions sandwiched between the radial cuts can be bent independently. As a result, even when the surface to be cleaned has a curved surface or the surface of the cushion or the like has elasticity, the operator can work while pressing the suction tool against the surface to be cleaned. Is flexibly deformed according to the curvature and deformation of the surface to be cleaned, so that the state where the dust collecting surface is in close contact with the surface to be cleaned is maintained. Therefore, dust or the like can be captured and sucked without the belt-like brush body being separated from the surface to be cleaned, and the efficiency of cleaning work can be improved.

Finally, if the entire shape of the dust collecting portion is a disc shape as in the invention described in claim 3, the dust collecting surface that comes into contact with the surface to be cleaned can be formed into an annular shape. A uniform dust collection effect can be exhibited in the entire circumferential direction. As a result, the operator can perform the cleaning work while moving the dust collection part freely in all directions diagonally forward, backward, left, and right without considering the shape of the dust collection part, which also improves the efficiency of the cleaning work. There is an effect.

  Below, embodiment of the suction tool for vacuum cleaners which concerns on this invention is described in detail based on FIG. 1 thru | or FIG.

(First embodiment)
FIGS. 1 to 7 relate to a first embodiment of the present invention, and FIG. 1 is a perspective view of a vacuum cleaner suction tool (hereinafter referred to as “suction tool”) viewed obliquely from above. The suction tool includes a suction pipe 2 connected to a substantially disc-shaped dust collection part 1 near the outer peripheral part thereof. Moreover, FIG. 2 is the front view which looked at the suction tool which concerns on this invention from the direction where the suction pipe 2 is not attached. The bottom surface of the dust collecting portion 1 is a dust collecting surface 4 in contact with the surface to be cleaned.

In this embodiment, since the thickness of the dust collecting part 1 is extremely thin, even if there is an obstacle above the surface to be cleaned, the edge of the dust collecting part 1 is inserted into a slight gap to remove dust.・ Suction can be performed, improving the efficiency of cleaning work.

In addition, a total of four intake portions 3 are arranged on the outer periphery of the dust collection portion 1 so as to face each other, and each intake portion 3 has an outer peripheral edge portion of the disk-shaped dust collection portion 1. The blister shape is inflated upward. Therefore, the intake portion 3 has a bowl-shaped intake hole 31 when viewed from the side, but the shape of the intake hole 31 is not limited to this, and the cross-sectional shape is substantially reverse concave with respect to the surface to be cleaned. The shape may be a shape having a gap of 1 mm or a shape in which a through hole is directly provided on the outer wall surface of the dust collecting portion 1.

FIG. 3 is a left side view of the suction tool according to the present invention, and FIG. 4 is a top view. In the present embodiment, the suction pipe 2 has a rectangular tube shape, and the connection port 21 at the end of the suction pipe 2 also has a thin rectangular shape. This is, for example, a suction port of a small hand-held vacuum cleaner for car interior cleaning. This is because it is assumed that the suction pipe 2 is directly inserted and directly connected. The shape of the suction pipe 2 is not limited to such a rectangular tube shape, and may be a cylindrical shape or other shapes according to the shape of an electric vacuum cleaner main body to be connected or an extension pipe extending from the vacuum cleaner main body.

5 is a bottom view of the suction tool according to the present invention, and FIG. 6 is a cross-sectional view of the suction tool viewed from the left side on the line indicated by “AA” in FIG. 7 is a cross-sectional view of the suction tool on the line indicated by “BB” in FIG. 4.

As shown in FIG. 5, the bottom surface of the dust collecting portion 1 is an outer periphery of a circular cavity portion 41 in which an annular dust collecting surface 4 that contacts the surface to be cleaned is connected to the suction pipe 2 through a connection hole 11. A belt-like brush body 42 made of an inclined pile fabric is stuck on the surface of the dust collecting surface 4 in an annular shape. Further, since the intake portion 3 has a blister shape, the intake hole 31 forms a groove portion connected to the cavity portion 41 on the dust collecting surface 4 on the bottom surface side.

  In any part of the dust collecting surface 4, the belt-like brush body 42 has the tip of the brush hair on the inclined pile fabric surface in contact with the surface to be cleaned inclined from the outer periphery of the dust collecting unit 1 toward the center. It is affixed as follows. Therefore, even if the operator moves the suction tool in any direction, the tip of the bristle of the belt-like brush body 42 on the opposite side to the moved direction enters into the joint area of the surface to be cleaned and removes dust, etc. Since it scrapes out, it can remove dust and the like in all directions.

When using the suction tool according to the present invention, the vacuum cleaner is operated, and the suction tool is reciprocated in an arbitrary direction while bringing the dust collection surface 4 of the dust collection unit 1 into close contact with the surface to be cleaned. Let it be used. Whatever direction is reciprocated, the brush strip brush body 42 on the opposite side of the dust collecting surfaces 4 to the traveling direction in the forward path is dust or the like during removal from the surface to be cleaned, dust and the like are removed forward movement It becomes a state captured at the tip of the hair. Next, in the return path, dust or the like captured at the tip of the bristle is detached from the bristle due to friction with the surface to be cleaned, but at that time, the cavity 41 in a negative pressure state moves directly above. Therefore, the separated dust and the like are immediately sucked into the vacuum cleaner from the connecting hole 11 through the suction pipe 2.

Naturally, during this period, the dust collecting surface 4 on the movement direction side removes and captures dust and the like during the backward movement, and suction is performed during the forward movement, so that the reciprocating movement of the dust collecting unit 1 is repeated, The dust collecting surfaces 4 that face each other along the direction of movement perform cleaning of the surface to be cleaned by repeating the cycle of removing dust, etc., capturing, separating, and suction alternately.

  In the present embodiment, as described above, since the shape of the dust collecting portion 1 is substantially disk-shaped and the dust collecting surface 4 is also annular, the reciprocating motion of the dust collecting portion 1 is possible in all directions of 360 degrees. However, the shape is not necessarily limited to these shapes. For example, even when the dust collection unit 1 is square and reciprocates only in the front-rear or left-right direction, the straight belt-like dust collection surfaces 4 are arranged in parallel to the front-back direction. Only the reciprocating movement may be performed, and the same cleaning effect can be expected with respect to the movement direction.

(Second embodiment)
FIGS. 8 to 14 relate to a second embodiment of the present invention, and FIG. 8 is a perspective view of FIG. In this embodiment, in place of the air intake holes 31 of the first embodiment , a total of four cuts 5 are arranged radially in such a manner as to face each other from the outer edge of the dust collecting portion 1 toward the center. The tip of the notch 5 extends to the cavity 41, and the tip is connected to the cavity 41 as it is.

  Therefore, even if the air intake hole 31 of the first embodiment is not provided, the tip of the notch 5 is connected to the cavity 41, so that the connected portion serves as an air intake hole, and the dust collecting surface 4 is the surface to be cleaned. It is prevented from adsorbing to the surface.

  9 is a front view of the suction tool according to the second embodiment, FIG. 10 is a left side view thereof, FIG. 11 is a top view thereof, FIG. 12 is a bottom view thereof, and FIG. Is a cross-sectional view of the cross-section on the line indicated by “” when viewed from the left side, and FIG. 14 is a cross-sectional view on the line indicated by “BB”.

As is clear from FIGS. 8 to 10, in the second embodiment, the dust collecting portion 1 is formed in a plate shape having a small cross section, and the material of the dust collecting portion 1 is, for example, a soft plastic or the like. It is possible to bend appropriately according to the external force by using the elastic material.

  Accordingly, as shown in FIG. 15, even when the surface to be cleaned is a curved surface, the dust collecting unit 1 is made to respond to the curvature of the surface to be cleaned by the operator working while pressing the suction tool against the surface to be cleaned. Since it temporarily bends, the state where the dust collecting surface 4 is in close contact with the surface to be cleaned can be maintained, and dust or the like can be captured and sucked without the belt-like brush body 42 being separated from the surface to be cleaned. It is.

Therefore, unlike the living room, the suction tool according to the second embodiment is also suitable for cleaning furniture or the like in which the surface of a car to be cleaned or the surface of a car bed or a sofa having a curved surface has elasticity. .

In the suction tool according to the second embodiment, the number of the cuts 5 is arbitrary. For example, as shown in FIGS. 16 and 17, seven cuts 5 may be provided. In this case, the degree of freedom of bending of the dust collecting portion 1 is increased, and the adaptability to the curved surface to be cleaned is further improved.

As mentioned above, although embodiment of the suction tool for vacuum cleaners concerning this invention was described in detail, this invention is not limited to the said embodiment, In the range of the technical idea of this invention, an improvement or a change is possible. They are possible and belong to the technical scope of the present invention.
