^ ¹ - ^f Hand-held device for cleaning blocked drains

The invention relates to a hand-held device for cleaning clogged drains, with an elastic suction cup and a handle arranged thereon.

The object of the invention is to improve such a hand-held device in such a way that it is simpler and more cost-effective to construct and manufacture and, through a special design of its handle, enables easy handling for the generation of a good suction and pressure effect for the cleaning process.

This object is achieved according to the invention in that the handle is designed as a suction-pressure chamber with a valve, preferably a flutter valve, provided between the suction-pressure chamber and the suction bell and an outlet for the liquid to be sucked in and discharged through the suction bell and/or the suction-pressure chamber.

Further features of the invention and further embodiments of the handle can be found in the subclaims.

The hand-held cleaning device for clogged drains according to the invention is, in an advantageous way, extremely simple in design and inexpensive to manufacture and, thanks to the design of the handle as a suction-pressure chamber, enables a good suction and pressure effect for the liquid to be sucked in and discharged again.

On the one hand, the suction force is created simply by moving the suction cup and the liquid is sucked into the housing-shaped handle and is automatically dispensed through a spout when the suction cup is pressed, with a flutter valve arranged in the passage between the suction cup and the handle, which automatically switches from suction to pressure effect.

The handle can also be designed as a telescopic tube or as a bellows, so that in conjunction with the suction cup the suction and pressure effect is achieved simply by squeezing and pulling apart the handle.

This handheld device is extremely compact and easy to use by anyone, and offers high utility value thanks to its cost-effective design and reliable function.

The drawing shows embodiments of the invention, which are explained in more detail below. It shows:

Fig. 1 a schematic representation in partial section of a hand-held device for cleaning blocked drains with a handle designed as a suction pressure chamber and a suction bell arranged on it,

Fig. 2 a schematic representation in partial section of a variant of the hand-held device with a telescopic suction-pressure chamber,

Fig. 3 is a schematic side view in partial

Cross-section of another variant of the hand-held device with a suction-pressure chamber formed by a bellows.

The hand-held device for cleaning blocked drains has an elastic suction cup (1) and a handle arranged thereon, which according to the invention is designed as a suction-pressure chamber (2, 3, 4) for the liquid to be sucked in by the suction cup (1) and/or the suction-pressure chamber (2, 3, 4).

Between the suction pressure chamber (2, 3, 4) and the suction bell (1) there is a valve (5), preferably a flutter valve, which allows the liquid from the suction bell (1) to pass into the suction pressure chamber (2) during suction and which is used to discharge the liquid from the suction pressure chamber (2, 3, 4)

I · · 1

dan passage (6) between suction bell (1) and suction-pressure chamber (2, 3, 4) is blocked.

The suction pressure chamber (2, 3, 4) is equipped with an outlet (7) from which the liquid can flow out and to which a drain hose can be connected if necessary.

Furthermore, this outlet (7) can be closed by a valve, preferably a flutter valve (B) ₁ when the liquid is sucked into the suction-pressure chamber (2, 3, 4) and only when the pressure builds up in the suction-pressure chamber (2, 3, 4) is this valve (8) opened to allow the liquid to flow out.

As shown in Fig. 1, the suction pressure chamber (2) is formed by a housing which itself forms the handle or is additionally equipped with a handle part (9). This housing can be designed in various basic shapes and can be cylindrical in height.

The outlet (7) is provided in the bottom area of the housing (2) next to the valve (5).

Furthermore, a wall (10) can be arranged in the housing between the side outlet (7) and the flutter valve (5), taking up a portion of the housing height, which practically forms an overflow wall.

•ϕ

Ωανάλιδαια The suction effect of this hand-held device according to Fig. 1 is achieved by the user opening the suction pressure chamber

(2) or its handle part (9) and moves the suction cup (1) up and down over the drain, so that a suction is created through which the liquid flows into the suction pressure chamber (2).

According to the embodiment of Fig. 2, the suction-pressure chamber

(3) formed by two telescopically interlocking and mutually displaceable telescopic tubes, which are sealed against each other by a circumferential seal (11) in the overlapping area and which are preferably held against each other by an internal compression spring (12) under spring tension.

A flutter valve (5) is also arranged in the passage (6) and the lower telescopic tube has the side outlet (7).

The upper telescopic tube is equipped with a handle knob (9) to facilitate gripping of the telescopic suction pressure chamber (3).

The further design according to Fig. 3 shows a suction pressure chamber (4) formed by a bellows, in which a flutter valve (5) is also arranged in the passage (6) and which shows the outlet (7) in the lower area. This bellows (4) can also be equipped with a handle knob (9).

It is also possible to integrate a compression spring into the bellows (4) .

In the two designs according to Fig. 2 and 3, by moving the telescopic tubes against each other or by compressing and pulling apart the bellows (4) in the suction-pressure chamber (3, 4), a suction and a pressure are generated, through which liquid is sucked in and pushed out of the outlet (7) by the pressure.

The suction pressure chamber (2, 3, 4) is each attached with a connecting piece (13) to the piece of the suction bell (1) forming the passage (6).
