Description

Suction nozzle for a vacuum cleaner and vacuum cleaner comprising such a suction nozzle

Technical Field

The present utility model relates to the field of vacuum cleaners provided with a vacuum cleaner nozzle, also called suction head, which allows to suck away dust and debris present on a surface to be cleaned, which may be for example a tile, parquet or laminate.

Background

Document FR2965164 describes a vacuum cleaner nozzle, which comprises in particular:

A body comprising a floor provided with a lower surface arranged towards the surface to be cleaned and a suction opening into the lower surface of the floor,

A connection sleeve connected to a suction tube of the cleaner, the connection sleeve being fluidly connected to the suction opening,

A hinge device for mechanically connecting the connection sleeve with the main body, said hinge device comprising a pivoting connection, also called transverse pivoting connection, defining a transverse pivot axis extending transversely to the main direction of movement of the suction nozzle of the cleaner and configured to allow the connection sleeve to tilt back and forth relative to the main body and about the transverse pivot axis, and

An anti-tilt stop provided on the main body behind the suction opening.

The presence of such an anti-tilt stop allows to limit the extent of tilting of the soleplate about the pivot axis when the user moves the cleaner nozzle over the surface to be cleaned, in particular to limit tilting of the soleplate backwards when the user pulls the cleaner nozzle backwards, so as to avoid lifting of the front part of the soleplate, which would detract from the suction performance of the cleaner nozzle.

However, when the above-described cleaner nozzle is used on a hard floor, the friction of the anti-tilt stopper on the floor causes noise. Furthermore, such friction may result in scratching the floor to be cleaned, especially when the latter is a fragile hard floor, such as parquet floor, and the refuse adheres to the anti-tilt stops.

Disclosure of utility model

The present utility model aims to overcome these disadvantages.

The technical problem underlying the present utility model is in particular to provide a suction nozzle of a vacuum cleaner which is simple and economical in construction, while reducing the noise generated by the suction nozzle of the vacuum cleaner and ensuring the protection of the floor to be cleaned.

To this end, the subject of the utility model is a suction nozzle for a vacuum cleaner, comprising:

-An anti-tilt stop provided on the body.

The anti-tilt stop includes a first row of bristles and a second row of bristles, the first row of bristles and the second row of bristles being located on opposite sides of a median longitudinal plane of the suction nozzle, each row of bristles extending substantially parallel to the median longitudinal plane of the suction nozzle.

The use of the anti-tilt stop formed by the first row of bristles and the second row of bristles allows for a significant reduction in noise generated by friction of the anti-tilt stop when a user moves the cleaner nozzle in a main direction of movement, i.e. in a direction of movement of the cleaner nozzle parallel to the mid-longitudinal plane of the cleaner nozzle.

Furthermore, this configuration of the anti-tilt stop allows to significantly reduce the risk of scratching the floor to be cleaned, since the anti-tilt stop is able to deform upon contact with the floor to be cleaned, which avoids a rigid contact between the anti-tilt stop and the floor to be cleaned.

In addition, the generally longitudinal orientation of each of the first and second rows of bristles limits drag generated by the anti-tilt stops, thereby limiting friction generated by the anti-tilt stops as the cleaner nozzle moves over the surface to be cleaned.

The arrangement of the first row of bristles and the second row of bristles on both sides of the median longitudinal plane of the suction nozzle of the cleaner also allows to increase the stability of the suction nozzle of the cleaner.

The vacuum cleaner nozzle may also have one or more of the following features, alone or in combination.

According to one embodiment of the utility model, the anti-tilt stop is configured to limit the magnitude of tilting of the body relative to the connecting sleeve about the transverse pivot.

According to one embodiment of the utility model, the anti-tilt stop is configured to interact with a surface to be cleaned when the cleaner nozzle is moved over the surface to be cleaned. This arrangement of the anti-tilt stops allows to further limit the tilting of the soleplate when the suction nozzle of the cleaner is moved in the main direction of movement.

According to one embodiment of the utility model, the anti-tilt stop extends from the lower surface of the base plate.

According to an embodiment of the utility model, each of the first and second rows of bristles extends parallel to the middle longitudinal plane of the suction nozzle or is inclined at an angle of inclination of less than 10 °, for example less than 5 °, with respect to the middle longitudinal plane of the suction nozzle.

According to one embodiment of the utility model, each of the first and second rows of bristles extends in a straight line. These arrangements allow further limiting the friction generated by the anti-tilt stop.

According to one embodiment of the utility model, the first row of bristles and the second row of bristles are spaced apart from each other by a distance less than the length of the suction nozzle of the cleaner. This arrangement of the first row of bristles and the second row of bristles allows limiting the lateral bulk of the suction nozzle of the cleaner.

According to one embodiment of the utility model, the bristles of each of the first and second rows of bristles extend from a plane containing the leading and trailing edges of the suction opening by a distance of between 2 and 6mm, for example about 4mm. Advantageously, the plane containing the suction opening leading edge and the suction opening trailing edge is substantially horizontal when the cleaner nozzle is placed on a surface to be cleaned.

According to one embodiment of the utility model, the bristles of each of the first and second rows of bristles have a height of greater than 5 mm. This arrangement of bristles ensures soft contact between the anti-tilt stop and the floor to be cleaned when the cleaner nozzle is moved, while allowing such contact to be maintained in the event that the surface to be cleaned may be uneven.

According to one embodiment of the utility model, the length of each of the first and second rows of bristles is between 10 and 40mm, advantageously between 15 and 30mm, for example about 22mm.

According to one embodiment of the utility model, the bristles of each of the first and second rows of bristles are configured to interact with, in particular to rub against, a surface to be cleaned as the cleaner nozzle is moved over said surface.

According to one embodiment of the utility model, the suction nozzle of the vacuum cleaner comprises a first fixing strip, which is fixed to the main body, for example to the base plate, in a detachable manner, and a second fixing strip, which is fixed to the main body, for example to the base plate, in a detachable manner, the bristles of the first row of bristles being fixed to the first fixing strip, for example by gluing, crimping or welding, and the bristles of the second row of bristles being fixed to the second fixing strip, for example by gluing, crimping or welding. This configuration of the cleaner nozzle can limit the manufacturing cost of the anti-tilt stop and thus the manufacturing cost of the cleaner nozzle.

According to one embodiment of the utility model, each of the first and second fixing strips may for example comprise a fixing groove in which the respective bristles are fixed.

According to one embodiment of the utility model, the first and second fixing strips are rigid, for example metallic.

According to one embodiment of the utility model, the first fixing strip is for example detachably fixed in a first strip groove provided on the body, for example on the lower surface of the base plate, and the second fixing strip is for example detachably fixed in a second strip groove provided on the body, for example on the lower surface of the base plate.

According to one embodiment of the utility model, the articulation device comprises an additional pivoting link, also called longitudinal pivoting link, defining a longitudinal pivot axis and configured to allow the articulation sleeve to tilt left and right with respect to the body and about the longitudinal pivot axis.

According to one embodiment of the utility model, the longitudinal pivot axis extends substantially parallel to a median longitudinal plane of the suction nozzle of the cleaner.

According to one embodiment of the utility model, the longitudinal pivot axis is located in the middle longitudinal plane of the suction nozzle of the cleaner. This arrangement of the longitudinal pivot axis makes the suction nozzle of the vacuum cleaner according to the utility model more ergonomic.

According to one embodiment of the utility model, the transverse pivot extends substantially perpendicular to the main direction of movement of the suction nozzle of the cleaner.

According to one embodiment of the utility model, the transverse pivot extends substantially horizontally when the suction nozzle of the cleaner is placed on a horizontal surface.

According to one embodiment of the utility model, the longitudinal pivot is configured to extend substantially horizontally or to be inclined with respect to the horizontal by an inclination angle of less than 10 °, for example less than 5 °, when the central longitudinal axis of the connection sleeve extends vertically and the suction nozzle of the cleaner is placed on a horizontal surface.

According to one embodiment of the utility model, the articulation device comprises a connecting member mechanically connecting the connecting sleeve with the main body, said connecting member being mounted in an articulated manner on the main body by means of a pivot connection, and the connecting sleeve being mounted in an articulated manner on the connecting member by means of an additional pivot connection.

According to one embodiment of the present utility model, the connection member includes:

A first connection portion comprising a pair of first fixing lugs spaced apart from each other and disposed opposite each other, said first fixing lugs being hingedly mounted on the main body by means of a pivot connection,

-A second connecting portion comprising a pair of second fixing lugs spaced apart from each other and arranged opposite each other, on which the connecting sleeve is hingedly mounted by means of an additional pivot connection.

According to one embodiment of the utility model, the first and second fixing lugs are angularly offset along the central axis of the connecting member by an angle of about 90 °.

According to one embodiment of the utility model, the suction nozzle of the vacuum cleaner comprises a flexible connection conduit fluidly connecting the suction opening with the connection sleeve.

According to one embodiment of the utility model, the connecting member defines an internal passage in which the flexible connecting conduit extends.

According to one embodiment of the utility model, the flexible connection pipe extends between the first and second fixing lugs.

According to one embodiment of the utility model, the first row of bristles and the second row of bristles are located behind the suction opening. This arrangement of the anti-tilt stops allows limiting the rearward tilting of the soleplate when the user pulls the suction nozzle of the cleaner backwards, thus avoiding lifting of the front part of the soleplate, which would impair the suction performance of the suction nozzle of the cleaner.

According to one embodiment of the utility model, the first row of bristles and the second row of bristles are at least partially located behind the transverse pivot. In other words, the anti-tilt stop is at least partially located behind the vertical plane containing the transverse pivot, i.e. at least partially located behind the transverse pivot, when the suction nozzle is placed on a horizontal surface.

According to one embodiment of the utility model the anti-tilt stop is offset backwards in relation to the transverse pivot axis, i.e. the anti-tilt stop is located completely behind the transverse pivot axis.

According to one embodiment of the utility model, the anti-tilt stop is located vertically below the rear of the floor.

According to another embodiment of the utility model, the first row of bristles and the second row of bristles are located in front of the suction opening. This arrangement of the anti-tilt stops allows limiting the forward tilting of the sole plate when the user moves the suction nozzle of the cleaner forward, thus avoiding lifting of the rear part of the sole plate, which would impair the suction performance of the suction nozzle of the cleaner.

According to one embodiment of the utility model, the anti-tilt stop is located vertically below the front of the floor.

According to one embodiment of the utility model, the body comprises an outlet fitting at least partially above the suction opening.

According to one embodiment of the utility model, the central axis of the outlet fitting is inclined with respect to the horizontal plane by an inclination angle of between 40 ° and 60 ° when the suction nozzle of the cleaner is placed on a horizontal surface. This arrangement of the suction outlet fitting limits the deformations experienced by the flexible connection pipe during use of the suction nozzle of the cleaner. In fact, under normal use conditions (i.e. the configuration in which the grip is deployed), the connection sleeve is generally inclined at an inclination angle ranging between 40 ° and 60 ° with respect to the horizontal plane.

According to one embodiment of the utility model, the suction opening is elongated and extends in an extension direction transverse to the main direction of movement of the suction nozzle of the cleaner, for example perpendicular to the main direction of movement.

Advantageously, the plane is substantially horizontal when the cleaner nozzle is placed on the surface to be cleaned.

According to one embodiment of the utility model, the anti-tilt stop is fixed relative to the nozzle body.

Fig. 1 to 17 show a vacuum cleaner nozzle 2 according to a first embodiment of the utility model.

The cleaner nozzle 2 comprises a main body 3 configured to move over a surface to be cleaned. The body 3 comprises a soleplate 4, for example made of plastic, provided with a lower surface 5 arranged to face the surface to be cleaned, and a suction opening 6, which opens into the lower surface 5 of the soleplate 4. As shown in fig. 15, the suction opening 6 is elongated and extends in an extending direction D1 perpendicular to the main moving direction D2 of the cleaner nozzle 2.

The base plate 4 further comprises a suction chamber 41 into which the suction opening 6 opens and an outlet connection 42 which likewise opens into the suction chamber 41. According to the embodiment shown in fig. 1 to 17, the outlet fitting 42 is located at least partially above the suction opening 6 (see in particular fig. 7 and 13) and towards the rear of the cleaner nozzle 2. Advantageously, the central axis of the outlet fitting 42 is inclined with respect to the horizontal plane by an inclination angle of between 40 ° and 60 ° when the cleaner nozzle 2 is placed on a horizontal surface.

The body 3 further comprises a cover 10 fixed to the base plate 4 and configured to at least partially cover the base plate 4.

The vacuum cleaner nozzle 2 further comprises a connection sleeve 7 which is in fluid connection with the suction opening 6, in particular with the outlet fitting 42. The connection sleeve 7 is connected to an accessory 8, which accessory 8 is in turn connected to the suction system (not shown) of the cleaner. Various cleaner variants are already present on the market and can be used with the cleaner nozzle 2 of the utility model; since these variants are well known to those skilled in the art, they will not be described in detail herein.

According to the embodiment shown in fig. 1 to 17, the accessory 8 comprises:

The suction tube 9 comprises a first end 9.1, for example removably connected to the connection sleeve 7, and a second end 9.2, opposite the first end, advantageously provided with a connection head,

An at least partially flexible suction hose 11, which is for example detachably connected to the second end 9.2 of the suction tube 9, and

A grip 12 comprising a long main grip portion 12.1 and a handle 12.2 configured to be gripped by a user to allow the user to manipulate the grip 12 and thus the suction tube 9.

The main grip portion 12.1 is hingedly mounted on the second end 9.2 of the suction tube 9 about a hinge axis which is substantially perpendicular to the longitudinal axis of the suction tube 9, the main grip portion 12.1 being hinged between an unfolded configuration (see fig. 1) in which the main grip portion 12.1 extends substantially parallel to the suction tube 9, and a folded configuration (see fig. 2) in which the main grip portion 12.1 defines an angle with the suction tube 9 of less than 180 °, for example about 90 °.

The cleaner nozzle 2 further comprises a hinge means 13 which mechanically connects the connecting sleeve 7 with the main body 3, in particular with the cover 10.

The hinge means 13 comprise a pivoting connection P1, also called transverse pivoting connection, which defines a transverse pivot axis X1 extending transversely to the main direction of movement D2 of the suction nozzle 2 of the cleaner. The pivot connection P1 is configured to allow the connection sleeve 7 to tilt back and forth relative to the main body 3 about the first pivot axis X1. Advantageously, the transverse pivot axis X1 extends perpendicular to the main direction of movement D2 of the suction cleaner nozzle 2 and extends horizontally when the suction cleaner nozzle 2 is placed on a horizontal surface.

The pivot connection P1 is more particularly configured such that the connection sleeve 7 is able to occupy, in particular, a first sleeve position (see fig. 17) in which the central longitudinal axis B of the connection sleeve 7 extends vertically and in the intermediate longitudinal plane P of the cleaner nozzle 2 when the main body 3 is placed on a horizontal surface, and a second sleeve position (see fig. 2 and 13) in which the central longitudinal axis B of the connection sleeve 7 extends horizontally and in the intermediate longitudinal plane P of the cleaner nozzle 2 when the main body 3 is placed on a horizontal surface. The first sleeve position may for example correspond to a storage position, also called a rest position, of the suction nozzle 2 of the cleaner.

The pivotal connection P1 is further configured such that the connection sleeve 7 is able to occupy a plurality of intermediate sleeve positions relative to the main body 3 between a first sleeve position and a second sleeve position, in each of which intermediate sleeve positions the central longitudinal axis B of the connection sleeve 7 extends in an intermediate longitudinal plane P of the cleaner nozzle 2 and is inclined relative to the vertical and horizontal (see in particular fig. 1).

The hinge means 13 further comprise an additional pivoting connection P2, also called longitudinal pivoting connection, defining a longitudinal pivot axis X2 and configured to allow the connecting sleeve 7 to tilt left and right with respect to the body 3 and about the second pivot axis X2, in particular starting from the first sleeve position. Advantageously, the longitudinal pivot axis X2 lies in the median longitudinal plane P of the suction nozzle 2 of the cleaner.

According to the embodiment shown in fig. 1 to 17, the longitudinal pivot axis X2 extends horizontally when the central longitudinal axis B of the connection sleeve 7 extends vertically and the cleaner nozzle 2 is placed on a horizontal surface. However, according to a variant embodiment of the utility model, the longitudinal pivot axis X2 may be inclined with respect to the horizontal plane, for example inclined forward upwards by an angle of inclination of less than 10 °, for example less than 5 °, when the central longitudinal axis B of the connection sleeve 7 extends vertically and the cleaner nozzle 2 is placed on a horizontal surface.

According to the embodiment shown in fig. 1 to 17, the hinging means 13 comprise a connecting member 14 mechanically connecting the connecting sleeve 7 with the body 3. The connecting member 14 is mounted in a hinged manner on the body 3, in particular on the cover 10, by means of a pivot connection P1, and the connecting sleeve 7 is mounted in a hinged manner on the connecting member 14 by means of an additional pivot connection P2.

According to the embodiment shown in fig. 1 to 17, the connecting member 14 comprises:

A first connecting portion 15 comprising a pair of first fixing lugs 15.1 (see fig. 10) spaced apart and arranged opposite each other, the first fixing lugs 15.1 being hingedly mounted on the body 3 by means of a pivot connection P1, and

The second connecting portion 16 comprises a pair of second fixing lugs 16.1 spaced apart and arranged opposite each other, the connecting sleeve 7 being mounted hingeably on the second fixing lugs 16.1 by means of an additional pivot connection P2.

Advantageously, the first securing ear 15.1 and the second securing ear 16.1 are angularly offset along the central axis of the connecting member 14 by an offset angle of approximately 90 °.

The cleaner nozzle 2 further comprises a flexible connection conduit 17 (see fig. 9 and 13) fluidly connecting the outlet fitting 42 with the connection sleeve 7. Advantageously, the connecting member 14 defines an internal passage in which the flexible connecting duct 17 extends. Thus, the flexible connection pipe 17 extends between the first fixing lugs 15.1 and between the second fixing lugs 16.1.

The cleaner nozzle 2 further comprises an anti-tilt stop 18 which is deformable and is located behind the suction opening 6 and below the rear of the sole plate 4. More specifically, the anti-tilt stop 18 is located at least partially rearward of the lateral pivot axis X1 (see, in particular, FIG. 7). In other words, the anti-tilt stop 18 is at least partially located behind the vertical plane containing the transverse pivot axis X1 when the nozzle is placed on a horizontal surface.

Advantageously, the anti-tilt stop 18 is offset rearward relative to the transverse pivot axis X1 and is therefore located entirely rearward of the transverse pivot axis X1.

The anti-tilt stop 18 comprises a first row of bristles 19 and a second row of bristles 21, which are located on either side of the median longitudinal plane P of the cleaner nozzle 2 and each extend transversely with respect to the transverse pivot axis X1. Thus, the first and second rows of bristles 19, 21 are different from each other and are separated from each other. Advantageously, each of the first and second rows of bristles 19, 21 extends in a rectilinear manner.

According to the embodiment shown in fig. 1 to 17, the first and second rows of bristles 19, 21 are symmetrically arranged with respect to the median longitudinal plane P of the suction nozzle 2 and extend parallel to the median longitudinal plane P of the suction nozzle 2. However, according to a variant embodiment of the utility model, each of the first and second rows of bristles 19, 21 may be inclined laterally with respect to the median longitudinal plane P of the suction nozzle 2 by an inclination angle of less than 10 °, for example less than 5 °. In other words, the first and second rows of bristles 19, 21 may be inclined to each other by an inclination angle of less than 20 °, for example less than 10 °.

Advantageously, the first and second rows of bristles 19, 21 are spaced from each other by a spacing distance Ds1 which is less than the length of the suction opening 6. The separation distance Ds1 may be between 50 and 150mm, advantageously between 60 and 100mm, for example about 82mm.

Each of the first and second rows of bristles 19, 21 may have a length of between 10 and 40mm, advantageously between 15 and 30mm, for example about 22mm, and the bristles of each of the first and second rows of bristles 19, 21 may for example have a height of more than 5 mm.

The bristles of each of the first and second rows 21 of bristles are configured to interact with, and in particular rub against, a surface to be cleaned as the cleaner nozzle 2 is moved over the surface to be cleaned. Advantageously, the bristles of each of the first and second rows of bristles 19, 21 extend from a plane containing the leading edge of the suction opening 6 and the trailing edge of the suction opening 6 by a distance Ds2 of between 2 and 6mm, for example about 4mm. Advantageously, said plane is substantially horizontal when the cleaner nozzle 2 is placed on a surface to be cleaned.

According to the embodiment shown in fig. 1 to 17, the suction cleaner nozzle 2 comprises a first fixing strip 22, which is, for example, detachably fixed to the main body 3, for example, to the base plate 4, and a second fixing strip 23, which is, for example, detachably fixed to the main body 3, for example, to the base plate 4. The first fixing strip 22 may be, for example, detachably fixed in a first strip groove provided on the main body 3, for example, fixed on the lower surface 5 of the base plate 4, and the second fixing strip 23 may be, for example, detachably fixed in a second strip groove provided on the main body 3, for example, fixed on the lower surface 5 of the base plate 4.

The bristles of the first row of bristles 19 are fixed to the first fixing bar 22, for example by gluing, crimping or welding, and the bristles of the second row of bristles 21 are fixed to the second fixing bar 23, for example by gluing, crimping or welding. Advantageously, each of the first and second fixing strips 22, 23 is rigid, for example metallic or made of plastic.

Each of the first and second fixing bars 22, 23 may, for example, comprise a fixing groove in which the respective bristle is fixed.

According to the embodiment shown in fig. 1 to 17, the vacuum cleaner nozzle 2 comprises a front scraping member 24 located forward of the front edge of the suction opening 6 and a rear scraping member 25 located rearward of the rear edge of the suction opening 6. Advantageously, the lower ends of the bristles of each of the first and second rows of bristles 19, 21 lie in or substantially in a plane which is substantially horizontal when the cleaner nozzle 2 is placed on a surface to be cleaned and which comprises the lower edges of the front scraping member 24 and the lower edges of the rear scraping member 25.

Fig. 18 shows a cleaner nozzle 2 according to a second embodiment of the utility model, which differs from the first embodiment shown in fig. 1 to 17 mainly in that the cleaner nozzle 2 comprises an additional anti-tilt stop 43, which is located in front of the suction opening 6 and is configured to limit the forward tilting of the main body 3 when the user moves the cleaner nozzle 2 forward, thus avoiding lifting of the rear part of the soleplate 4, which would impair the suction performance of the cleaner nozzle 2.

Advantageously, the additional anti-tilt stop 43 comprises a third row 44 and a fourth row 45 of bristles, which are located on both sides of the median longitudinal plane P of the suction nozzle 2 and extend parallel to the median longitudinal plane P of the suction nozzle 2. The configuration of the additional anti-tilt stop 43 may be, for example, substantially the same as the configuration of the anti-tilt stop 18.

According to another embodiment of the utility model, not shown in the figures, the anti-tilt stop 18 may not be located behind the suction opening 6, but in front of the suction opening 6.

Of course, the utility model is in no way limited to the embodiments described and illustrated, which are merely illustrative. Modifications may be made without departing from the scope of the utility model, particularly in terms of the constitution of the various elements or by substitution of technical equivalents.
