As a result, in turn, it is possible in a simple manner to wrap the hose around the suction head with a released securing element and then to secure the corresponding winding package to the suction head.

In particular, a fixing element for the securing element is then arranged at a height distance from the at least one retaining element. The securing element can be fixed to the fixing element. If the securing element is fixed to the fixing element, then the securing element extends between the holding element or an area in the vicinity of the holding element to the fixing element. This makes it possible to secure a winding package in particular against lateral falling out and preferably press against the side wall of the cleaner head.

It is advantageous if the fixing element is designed as a suspension element for a loop. As a result, the fixation of the securing element to the fixing element is achieved in a simple manner.

It is advantageous if the fixing element is arranged on or in the vicinity of an upper edge of the side wall or is arranged on an upper side of the suction head. As a result, a large vertical distance can be bridged with the securing element in order in particular to be able to secure a winding package with several turns. This in turn makes it possible To stack windings one above the other, in order to minimize the width increase of the suction head even when the suction hose is wound up.

In one embodiment, the fixing element is arranged so that it does not protrude beyond a surface of an upper side of the suction head. It is arranged for example on the side wall or offset from the top with respect to the remaining surface thereof.

For example, the securing element is designed as a clamping element and in particular designed to be elastic in elasticity and is for example a rubber band or comprises such. This makes it easy to achieve a backup of a Windungspakets.

In particular, the securing element is fixed to the at least one retaining element or on the side wall in the vicinity of the at least one retaining element and in particular releasably fixed. This makes it easy to secure a winding package.

An embodiment of a teat 10 according to the invention ( FIGS. 1 and 2 ) is a wet-dry vacuum cleaner. It can also be a pure dry-sucker or a pure wet-sucker. The nipple 10 includes a suction cup 12 having a wall 14 and a bottom 16.

Through the wall 14 and the bottom 16, an interior 18 is formed, in which directly or via a bag suction material is receivable.

The suction container 12 has a connection point 20 for a suction hose 22. The suction hose 22 is in particular a spiral hose. At the junction 20 of the suction hose 22 is in particular releasably fixed.

The teat 10 further comprises a teat head 24. The teat head 24 has a side wall 26 and an upper side 28 which is formed, for example, on a lid wall which is connected to the side wall 26. The top 28 is formed at the portion of the cleaner head 24 which has the greatest distance to a horizontal plane (with respect to the direction of gravity g) when the nipple 10 rests on this plane. This cover wall is, for example, integrally connected to the side wall 26. The top 28 is formed, for example flat, in particular to provide a storage area. It can also be curved, for example. There may also be a continuous transition from side wall 26 to top 28.

Via the side wall 26 and the upper side 28, an inner space 30 is formed on the suction head 24. The side wall 26 may, for example, have four sides, wherein adjacent sides are transverse and in particular perpendicular to each other. It can also have a convex curved, closed wall. In the interior 30, a turbine device 32 with a motor device 34 is arranged. Furthermore, the turbine device 32 is preceded by a filter device 36 with one or more dust filters, wherein the filter device 36 is arranged in the inner space 30.

The suction head 24 can be placed on the suction container 12 and fixed by a fixing device 38 with this. For emptying the suction container 12 of suction material (which is received in a bag or directly in the interior 18), the suction head 24 can be removed from the suction container 12.

The fixing device 38 comprises, for example, one or more latching elements 40, via which the suction head 24 can be latched to the suction container 12.

In one embodiment, the side wall 26 has at or near a lower edge 42 a reinforcing region 44 on which the fixing device 38 is formed.

"Bottom" refers to the direction of gravity g, when the teat 10 is placed on a base on the teat container 12, for example via wheels 46.

On the suction head 24, one or more holding elements 48 (at or in the vicinity of the lower edge 42) (FIG. FIGS. 1 to 3 ) arranged. A holding element 48 is fixed or releasably fixed to the side wall 26. The holding element 48 is in particular at a height distance up to the connection point 20th

A holding element 48 is for example hook-shaped. It has an insertion space 50 for a turn 53 of the suction hose 22. The insertion space 50 is bounded by a wall 52, wherein the wall surface 55 is curved to the insertion space 50 and in particular is concavely curved. For example, the wall 52 is cylindrical at least in a partial area. The wall 52 is formed so that the inserted winding 53 (see Figures 2 and 3 ) of the suction hose 22 down (in a direction 54 in accordance with FIG. 3 ) and against lateral falling out (in a direction 56 according to FIG. 3 ) is secured away from the side wall 26 away. When the sucker 10 is placed with the suction container 12 and the wheels 46 on a horizontal surface, then corresponds the direction 54 of the direction of gravity and the direction 56 is a direction transverse and in particular perpendicular to the direction 54.

The insertion space 50 is in particular designed so that a single turn (the turn 53) can be inserted.

On its outside, the holding element 48 has a convex surface 58. As a result, corners and edges are avoided. Furthermore, it is then also possible to create a securing element on this outer side, as will be described in more detail below.

A width of the holding element 48 (and thus of the insertion space 50) and in a direction transverse to the directions 54 and 56 is in particular at least 3 cm.

About the at least one holding element 48 can, as in FIG. 2 indicated, the suction hose 22 in one or more windings wrap around the suction head 24. The sucker head 24 provides a kind of winding core ready. The support member 48 supports the windings downwardly and prevents falling in the direction 54. The lowermost turn 53 is secured against lateral falling out in the direction 56.

The holding element 48 is preferably arranged at a distance from the connection point 20 (based on the course of the suction hose 22) which is at most 25% and in particular at most 10% of the length of a (complete) turn of the suction hose around the suction head 24. As a result, excessive sagging in the region between the connection point 20 and the nearest holding element 48 can be prevented.

There may be a holding element 48 or more holding elements. In FIG. 1 and 2 Further holding elements 60a and 60b are indicated.

If a plurality of holding elements are provided, then in particular a first holding element (the holding element 48) and a second holding element (the holding element 60a) are arranged symmetrically with respect to the connection point 20. As a result, a simple winding can be achieved.

The holding element or elements 48, 60a, 60b are arranged on or in the vicinity of the lower edge 42 of the suction head 24 in such a way that one turn and in particular a plurality of turns can be wound around the suction head 24 as a winding core. The lower turn 53 is supported directly on the holding element 48. An adjacent overlying turn 62 (FIG. FIG. 3 ) is supported on the lower turn 53. One of the winding 62 adjacent next turn 64 in turn is supported on the winding 62 from. There is thus a winding package 66, which is supported on the one or more holding elements 48.

The holding element or elements 48 are arranged such that with typical length of the suction hose 22, the winding package 66 does not protrude beyond the upper side 28, that is to say that the side wall 26 provides a contact surface for the winding package 66.

The retaining element 48 is associated with a securing element 68. The securing element is fixed via a fixing device 70 on the holding element 48 and in particular releasably fixed. For example, the securing element 68 itself is fixed to the fixing device 70 and the fixing device 70 in turn is fixed to the holding element 48, in particular in the region of the convex surface 58.

It is also possible that the securing element 68 is not fixed directly to the holding element 48 via its fixing device 70, but rather to the side wall 26 in the vicinity of the holding element 48.

If a fuse element 68 needs to be replaced, then an operator can accomplish this in a simple manner by releasing the fixing device 70 and replacing the fuse element 68.

The securing element 68 is assigned a fixing element 72, which sits on the suction head 24 at a height distance from the holding element 48. For example, such a fixing element 72 is integrally formed on the side wall 26.

A fixing element 72 is formed for example as a suspension element, in which the securing element 68 can be suspended. For example, the fixing element 72 is designed as a type of hook into which a loop 74 of the securing element 68 can be suspended.

In one embodiment, the fuse element 68 itself is formed as a loop 74 ( FIG. 4 ). As a result, the securing element 68 can be suspended as it were in the fixing element 72 as a whole.

In an alternative embodiment, a securing element 76 is provided which, for example, has a ring 78 which forms a loop 80. The ring 78 is seated on a part 82 of the securing element 76, on which in turn the fixing device 70 is seated. The ring 78 is made of a metallic material, for example. Via the loop 80 of the ring 78, the securing element 76 can be attached to a fixing element 72.

The securing element 68 is in particular designed to be elastically elastic as an elastic tensioning element. In a securing element 76, in particular, the part 82 is designed to be stretch-elastic. In the FIGS. 4 and 5 this is indicated by the double arrow with the reference numerals 84a and 84b. As a result of the expansion-elastic design, the winding package 66 can be pressed against the side wall 26 when the securing element 68 or 76 is fixed to the associated fixing element 72.

A fixing member 72 is particularly arranged at or near an upper edge (a rim at the upper side 28) of the side wall 26. A fixing element 72 can also be arranged directly on the upper side 28.

In one embodiment (not shown in the drawings), the fixing element 72 is arranged and formed such that it does not protrude beyond a surface of the upper side 28.

The suction head 24 according to the invention or the acid 10 according to the invention functions as follows with respect to the "stowing" of the suction hose 22:

For winding up the suction hose 22 around the suction head 24, the securing element or elements 68 are released from the associated fixing element or elements 72. The lower turn 53 of the suction hose 22 is inserted into the holding element or elements 48, the suction hose 22 being wound around the suction head 24 (about the side wall 26 thereof). Then, the winding 62 are deposited on the lower winding 53, the winding 64 on the winding 62, etc. Thus, the winding package 66 is produced. This Windungspaket 66 is supported on the support member 48 and is thereby secured against falling down in the direction 54. The lower turn 53 is secured against falling out in the direction 56.

The securing element 68 is then hung on the fixing element 72. As a result, the winding package 66 as a whole is secured against falling out in the direction 56. With an elastic design of the securing element 68, the winding package 66 can be tensioned against the side wall 26 (by corresponding pressurization via the securing element 68).

The inventive solution a simple and space-saving storage of the suction hose 22 is possible. This can be around the Wrap side wall 26 and a corresponding winding package 66 can then also "hold together".

A securing element 68 forms, in particular, a flexible tensioning element, wherein in turn advantageously the flexibility is achieved by means of a stretching elasticity.
