Abstract

(57) SUMMARY The present invention relates to a nozzle for a vacuum cleaner for cleaning hard and / or soft surfaces. When cleaning the inside of a room using a suction cleaner, a situation arises in which it is desired to appropriately switch between cleaning the floor using a floor nozzle and cleaning furniture, textiles, and the like using a dust brush or a flat nozzle. In order to replace the nozzle, the user has to remove the floor nozzle and its wander in order to connect the dust brush or the flat nozzle with free hands, which is an obstacle to the operation. The same applies to the reverse switching. The present invention solves this problem, and the dust brush / flat nozzle is configured so that the floor nozzle wand 6 can be easily inserted into the nozzle body 3. The dust brush / flat nozzle remains attached in place on the hose handle. Without the floor nozzle and wand, a dust brush / flat nozzle with a convenient contact angle is obtained.

TECHNICAL FIELD OF THE INVENTION

The present invention relates to a suction cleaner nozzle for a suction cleaner having a hard and / or soft surface. This nozzle was connected at one end to a suction cleaner hose and at the other end had a clear space around it for mounting a wand for the floor nozzle on the inner tube. An internal tube is provided.

[Prior Art and Problems to be Solved by the Invention]

Swedish Patent No. 509 890 discloses a single nozzle. This nozzle can be left in place in place on the suction cleaner even when the floor nozzle wand is connected to the suction cleaner. This makes it easy to switch between using the dust brush nozzles and using the floor nozzles. The disadvantage of this arrangement is that the dust brush nozzle, i.e. the fitting provided on the hose handle, depends on the length of the hose handle so that the hose mouth is correctly positioned with respect to the inclined opening of the nozzle body. It is that you are. This becomes a problem. This is because the length of the hose handle can vary between models.

[0003]

[Means for Solving the Problems]

The object of the present invention is to eliminate the drawbacks mentioned above. The above drawbacks are overcome by providing the tube integrally within the dust brush nozzle so that the hose handle can be inserted into one end of the dust brush nozzle and the wand can be fixed to the other end. This provides a multi-purpose dust brush nozzle or a flat nozzle with a convenient contact angle (claim 6). This nozzle does not have to be moved from its working position when the floor nozzle and wand are being used. The user can easily switch between floor cleaning and use with a dust brush / flat nozzle without having to put down the floor nozzle and wand to free one hand.
According to the invention, it is also possible to combine a dust brush and a flat nozzle as a combination nozzle, thus having an inherent ease of use (claim 5).

DETAILED DESCRIPTION OF THE INVENTION

Hereinafter, the present invention will be described in detail with reference to the attached FIGS. 1 and 2 show a flat nozzle, FIGS. 3 and 4a show a dust brush nozzle, and FIGS. 5 and 6a show a combination nozzle.

FIGS. 1 and 2 are a perspective view and a cross-sectional view, respectively, of a nozzle body 3 having a hole at one end for fitting the hose handle 2 snugly. The inside of the nozzle is composed of a tube 5 to which the wand of the floor nozzle is fixed when necessary. The nozzle body 3 has an opening at its end 4 distal from the suction cleaner. This opening has a shape that is cut while being inclined with respect to the central axis of the nozzle body. The inclination angle of this opening is about 45 ° with respect to the central axis. The length of the inner tube is set such that the opening of the tube is located approximately at the end of the beveled opening proximal to the suction cleaner. The wand can be easily attached to the inner tube by pressing the end of the wand against the distal end of the inner surface of the nozzle body and inserting it inside the nozzle body. If the inner tube of the nozzle body and its outer shell are of the correct size, the wall 6 slides exactly into the inner tube 5. The angle of inclination of the nozzle body 3 of about 45 ° is chosen so that the surface of the inclined opening is substantially horizontal when the hose handle 2 is also held manually by hand when cleaning the floor with a floor nozzle. ing.

The slanted end of the opening 4 is constructed so that it can be used as an effective and quiet flat nozzle, for example, when suction-cleaning a fabric. For example, toothed cutouts may be formed in this end, whereby air is sucked in through these cutouts and the dust from the cleaned surface is taken up. This end may be covered with an adhesive material such as Velcro®.

3 and 4 are a perspective view and a sectional view showing the brush head 1, respectively. The brush head 1 is mounted on a beveled end 4 of a nozzle body 3, the end itself of which forms an angle of approximately 45 ° with the longitudinal axis of the nozzle body. Thus, a dust brush nozzle with the possibility of being retained by having a contact angle made convenient by the inclined opening 4 of the nozzle body is formed, the wand 6 being the inner tube 5.
Be easily guided to. The bristles of the brush can also have different lengths along the circumference to further improve the contact angle. Further, these bristles may be oriented somewhat outward from the centerline of the nozzle body to increase the suction surface and facilitate insertion of the wand 6.

Finally, FIGS. 5 and 6 show a perspective view and a sectional view of the combination nozzle, respectively. In this combination nozzle, the brush head 1 shown in FIGS. 3 and 4 is replaced with a brush 8. The brush 8 is fixed to a tube 7 which is slidable in the length direction along the nozzle body 3. The tube 7 has two end positions and is retained by snap-fastening in each of these positions. The structure relating to this snap-fastening is not shown. One of these two end positions is shown in FIG.
And FIG. 6a, the brush head is selected to work when the wand is removed, and the other position is the nozzle for using a flat nozzle, as shown in FIGS. 5b and 6b. The brush head is selected to be retracted far enough from the tilted opening 4 to expose the tilted opening 4 of the body 3. The wand 6 can be easily attached to the inner tube 5 together with the brush head 8 in any of the above positions. These two snap-on positions can be configured by various means. At that time, the locking force due to the snap causes the brush head 8 to be in a predetermined position while being sucked by the brush head 8 in the use position, or the brush head 8 being in the retracted position while being sucked by the flat nozzle 4. Is sufficient to hold the tube 7, however, on the other hand, it is set so that the tube 7 and the brush head 8 can be easily slid between the two positions. At both end positions, one end of the tube 7 substantially coincides with the corresponding end of the nozzle body 3. Since the tube 7 is restrained from moving along the nozzle body, rotation around the nozzle body is prevented. Although not shown in FIGS. 5 and 6, this constraint can be realized by a known means such as a spline or an elliptical cross section provided on the outer side of the nozzle body 3 and the inner side of the tube 7.

It is obvious that a nozzle specially configured for additional functions can be fitted in place on the inner tube 5 of the wand 6, with all the nozzles mentioned above being placed in place.
