Japanese Unexamined Patent Publication No. 2001-8865

Wiping and cleaning the above-mentioned places and objects is troublesome because dust easily scatters.

It is difficult to suck with a vacuum cleaner, and if the nozzle is large, it will knock down or damage things, and if the nozzle is small, it will have to be moved many times, so dust will easily remain and it will be inefficient.

Nozzles with brushes are easily scratched and dust is likely to remain because they are not wiped, and it is difficult for the brush to get in the way or remove dust on the brush or the like in a narrow place.

Further, it is not preferable from the viewpoint of hygiene to use the nozzle used in a dirty place on a table or the like.

The nozzle described in Patent Document 1 having a chevron-shaped tip performs suction cleaning and wiping cleaning at the same time, but it has a large shape and cannot be freely moved in the above-mentioned place, and cannot be used for small items.

The nozzle of this vacuum cleaner sucks and removes dust such as the above-mentioned objects in places with many objects, places with limited space, and objects in those places while efficiently wiping them without damaging the cleaning surface, and also keeps the nozzle itself clean. Provide a vacuum cleaner nozzle that can.

A suction unit 3 having a suction port of a vacuum cleaner, a connecting portion 5 for connecting the hose pipe of the vacuum cleaner, and a connecting portion 4 for connecting the suction portion 3 and the connecting portion 5 are provided, and the suction portion 3 is provided with an air flow. A vacuum cleaner characterized in that a wiping body 2 which is formed in a hollow shape long in the road direction, is bent at an blunt angle, has a suction port at least on the bottom surface, and has a wiping portion for wiping dust is attached to and detached from the outer periphery of the suction portion 3. Aspirator.

According to the above, since only the suction part 3 of the suction body 1 is in contact with the cleaning surface and does not have a brush, the nozzle can be easily inserted even in a place with a lot of objects or a place where the space is limited, and the suction body 1 can be compactly vertically and horizontally It can be moved efficiently vertically and upwards. Further, since the wiping body 2 is attached and detached, it can be washed with water and easily dried when the wiping body is removed.

When the wiping body 2 is attached to the outer periphery of the suction portion 3, it has a wiping portion at least on the bottom surface of the suction portion 3 and is provided with an opening engaged with the position and size of the suction port of the suction portion 3.

The opening of the wiping body 2 is not simply a line of small holes, but an opening that matches the position and size of the suction port so that dust can be efficiently sucked from the suction port.

A nozzle in which the wiping body 2 is attached to the outer periphery of the suction portion 3 of the suction body is used.

Due to the above, it is easy to fit not only a flat surface but also a curved surface, and it is easy to use it for small items.

It is hygienic because it can remove dust from places with a lot of things, places with limited space, or things in that place with a vacuum cleaner without damaging the cleaning surface, and can be sucked and removed while wiping efficiently, and the nozzle can be kept clean. And the labor of housework is also reduced.

It is a perspective view seen from the bottom of the nozzle of a vacuum cleaner. It is a perspective view of a suction body. (A) is a bottom view of the suction body, and (B) is a partially enlarged cross-sectional view of the suction body of line AA. This is an example of the suction port of the suction part. This is an example of a wiping body.

Hereinafter, examples of the present invention will be described with reference to the drawings.

FIG. 1 is an example showing the embodiment of the present invention.

The nozzle of this vacuum cleaner is composed of a suction body 1 and a wiping body 2. The wiping body is inserted into the suction body, and in this state, it is connected to a hose pipe of the vacuum cleaner to suck and remove dust while wiping it.

In FIG. 2, the suction body 1 is connected to a suction portion 3 having a suction port of a vacuum cleaner, a connection portion 5 of a hose pipe of the vacuum cleaner, and a suction portion 3 having a different cross-sectional shape perpendicular to the air flow path direction. A connecting portion 4 for connecting the portions 5 is provided and communicated with the connecting portion 4.

The suction portion 3 is formed in a flat hollow shape that is long in the direction of the air flow path, and the suction portion is bent at an obtuse angle with the suction port facing down so that only the bottom surface of the suction portion is in contact with the cleaning surface. The cross-sectional shape of the suction portion perpendicular to the air flow path is such that the upper side is several millimeters shorter than the lower side and both corners of the upper side are rounded.

In FIGS. 2 and 3, fixing portions 6 and 6A for sandwiching and fixing the wiping body 2 are provided on the upper and lower surfaces near one end of the connecting portion 4 close to the suction portion 3. If the wiping body 2 is stably inserted into the suction body 1, the fixing portions 6 and 6A may not be provided.

As shown in FIG. 3, the suction ports are opened at two locations 8 and 9 at the tip 7 and the bottom surface of the suction portion. As for the suction ports on the bottom surface, the suction port 8 closer to the tip has a triangular shape with rounded corners, and the other suction port 9 has a substantially elliptical shape, and the intervals are evenly spaced.

The suction portion 3 is formed gradually smaller in the width direction and the height direction from the bottom 8A of the suction port closer to the tip toward the tip, the width direction of the tip is substantially trapezoidal, and the upper surface is in the height direction. The upper surface is formed shorter than the lower surface so that the tip is cut on a slope so that dust can be easily sucked.

In order to divide the suction force, the inside of the suction portion 3 is provided with a flat surface 10 that largely divides the upper part from the bottom 8A of the suction port closer to the tip to the front of the connecting portion 4. The flat surface 10 maintains the suction force around the tip.

The wiping body 2 has a wiping portion for wiping dust on the outside, and is formed in a hollow shape with both ends open. When the wiping body 2 is attached to the outer periphery of the suction portion 3, it has a wiping portion on the bottom surface of the suction portion 3 and is provided with an opening engaged with the position and size of the suction port of the suction portion. Since only the wiping part comes into contact with the cleaning surface, the cleaning surface is not damaged.

The mode for carrying out the above-mentioned invention is an example, and the shape of the cross section of the suction unit 3 perpendicular to the air flow path direction may be a shape such as a substantially circular shape or a substantially semi-circular shape. It may be hollow. If there are few parts on the bottom surface that come into contact with the cleaning surface, such as a substantially circular shape, the suction port may be provided near the bottom surface.

The suction port may be opened at least on the bottom surface of the suction portion 3, and may be opened on the tip, elevation, upper surface, or the entire circumference. In addition, various openings such as circular, square, linear, grid-like, and small and large number of openings can be considered. Since the suction portion 3 is used more frequently on the tip side than the half in the longitudinal direction, it is preferable to provide suction ports separately on the tip side and the root side of the suction portion 3.

When the suction port is provided on the outer periphery other than the bottom surface, the surface for dividing the suction force is not limited to the above-mentioned flat surface 10, and as shown in FIG. 4, for example, when the suction port is provided below the elevation surface, the flat surface 10 stands up. Surround the suction port on the elevation along the inside of the surface so that the suction ports on the adjacent bottom surface and the suction port on the elevation use the same suction force. As described above, when one of the suction ports on the bottom surface is in contact with the cleaning surface, the suction force of the suction port on the elevation surface adjacent to the suction port on the bottom surface in contact with the cleaning surface is mainly increased.

As the handle, the handle of the vacuum cleaner is used, but if necessary, the handle may be formed on the suction body 1.

In FIG. 5, the wiping portion of the wiping body 2 may be provided on an elevation surface or the entire circumference. The entire wiping body may be a wiping part. Similar to the suction port of the suction part, the opening of the wiping body can be circular, square, grid-like, small and large in number, linear or radial cuts, etc. Be done.

Further, instead of forming an opening in the wiping body 2, when forming the wiping body, a gap such as a linear shape or a grid shape may be formed in advance. In any case, the opening may be an opening engaged with the position and size of the suction port of the suction portion so that dust can be sucked efficiently.

The wiping part of the wiping body may be made of a material that wipes dust, and fibers, non-woven fabric, paper, etc. can be considered, and depending on the material, it can be washed and used many times or can be disposable.

In addition, even if the nozzle of the vacuum cleaner is not replaced depending on the application, the nozzle can be changed to a nozzle having a different application simply by replacing the wiper body having a different material, thickness, range, shape, brushed length and density of the wiping part.

Further, the wiping body may be a single wiping body even if it is not formed in a hollow shape, and when it is fixed by a suction body, it may be pinched, a protrusion may be formed and hooked, a magic tape may be provided, or a cut may be provided. A fixing part is provided on the outer periphery of the suction body, such as fixing with an elastic member such as plastic or rubber containing the material, and the wiping body is attached to the suction part. The fixing portion is preferably provided above so as not to get in the way. When the suction body is not provided with a fixing portion, a protrusion and a notch are provided in the wiping body so that the suction body can be fixed by the wiping body by hooking the notch on the protrusion or attaching the notch to the suction body by an adhesive means such as tape.
