Abstract

The invention relates to a drain pipe cleaner that is equipped with an infra-sound wave generator. Here, a drain pipe blockage is unblocked with the help of a piston or an oscillating diaphragm, which makes large stroke movements and thereby generates infra-sound waves or pressure waves. The pressure waves or pressure pulses are controlled by a controller. An electronic circuit generates electrical sine waves or signals in the form of pulses. The signals are amplified by an electronic amplifier and then set in motion by an electromagnet or an electric motor, the oscillating membrane or the piston. The stroke movement of the piston or the oscillating diaphragm generates air pressure waves that are directed into the drain pipe. The swinging movements loosen the blockage.

Description

The invention relates to a drain pipe cleaner equipped with an oscillating membrane that generates strong air pressure waves.

The pipe cleaners or drain pipe cleaners are manufactured in many designs and shapes.

There are drain cleaners that work with compressed air. A majority of them have a water pressure pump that is built relatively simply and a valve that releases a pressure wave when triggered that can free the pipe. This type of drain pipe cleaner is very environmentally friendly and ideal for domestic use and not too stubborn pipe blockages. It clears drains very quickly and no chemicals are needed.

There are also numerous versions in which a rope with a brush is inserted into the drain pipe in a rotating manner. The rotation cleans the pipe inside and frees it from layers of dirt. However, a stubborn clog is difficult to unclog because this device does not act strongly on the clog site, but rather "brushes free" the walls of the pipe.

The invention specified in claims 1 to 9 is based on the problem of designing a pipe cleaner or drain pipe cleaner in such a way that it acts on a clogged point in a pipe with the help of pressure waves, which loosens them and the pipe can be freed.

• - rein mechanisches Vorgehen,
• - einfache Handhabung,
• - der Rohrreiniger oder Abflussrohrreiniger ist sehr wirkungsvoll, weil er schnell hintereinander starke Luftdruckwellen erzeugt, welche die Verstopfung aus dem Weg räumen.

This problem is solved with the features listed in claims 1 to 9 for protection. Advantages of the invention are:

• - purely mechanical procedure,
• - easy to use,
• - the pipe cleaner or drain cleaner is very effective because it quickly creates powerful air pressure waves that clear the clog out of the way.

• 3 die Steuerung, die den Elektromagnet mit Impulsstrom steuert,

Embodiments of the invention are based on the 1 until 5 explained. Show it:

• 1 and 2 one version each with a membrane and an electromagnet (built almost like a loudspeaker),
• 3 the controller that controls the electromagnet with pulse current,
• 4 the variant with the piston, which is moved by an electromagnetic coil,
• 5 the piston, which is moved by an electric motor.

The invention is a drain cleaner equipped with an electromagnetically driven membrane (or piston) that uses air pressure waves that can unclog the clogged area with air over and under pressure. The pressure waves "hit" the clogged material, which can free a pipe.

The membrane 1 and the electromagnet 2 work almost like a loudspeaker and are similarly built ( 1 and 2 ). However, the membrane is much more stable here and significantly lower frequencies are used here. Rather, it is infra-sound waves with large amplitudes or air pressure impulses that are generated here. The membrane consists of a somewhat firm material and is attached to the edge 4 with a folded ring 3, as in the case of the loudspeaker. The lifting movements are very large here. The membrane should be able to cover a stroke distance of approx. 2 - 5 cm during the swinging movements, so that the air in the tube can then be compressed and decompressed really well. These alternating compressions and decompressions of the air inside the tube create compressive forces on the clog 6 which produce a loosening effect. The oscillating membrane (membrane) 1 generates strong air pressure waves in the drain pipe 5, which can more or less push the clogging material 6 back and forth by air pressure. The pressure wave opening 8 and the housing 9 of the drain cleaner 10 can be attached tightly to the drain pipe by means of an adapter 7 . Similar adapters are also used with conventional pipe cleaners with compressed air pumps.

The controller 11, which controls the electromagnet 2, can be coupled with a sine wave generator, or even better with a pulse generator 12, which generates signals in the form of pulses ( 3 ). The abruptly increasing amplitudes in the impulse current push the oscillating diaphragm 1 accordingly quickly and thus generate a series of strong air pressure waves. The higher the repetition rate of the impulses, the greater the effect.

The version with the electromagnetic coil 17 ( 4 ) or by an electric motor 18 movable piston 19 ( 5 ), works similarly. The electric motor can be connected to the piston 19 by means of a connecting rod 20 and push it back and forth at an adjustable speed. The variant with the electromagnet pulls the piston into the coil and pushes it out again, or this is done by a return spring 23.

When using this drain pipe cleaner, an adapter 7 made of plastic or rubber is used, as with conventional air pressure pipe cleaners, with which the entrance 13 in the drain pipe is suitably and tightly enclosed. As soon as this is done, the membrane can be set in pulse oscillations via a switch 14 which is coupled to the trigger 15 of the pipe cleaner 10 . The membrane is installed in a hollow cylinder housing 9 of the drain cleaner and can have a larger diameter than the opening 13 of the drain pipe. The larger the diameter of the membrane, the greater the volume of air that is moved with it. With a membrane with a diameter of 100mm and a stroke movement of 20mm, approx. 157cm ³ of air is moved back and forth. The frequency can be from a few Hz to several hundred Hz. Both the frequency and the stroke movements of the membrane or the piston can be controlled electronically by the controller or a regulator 21. The body of the drain cleaner 10 also houses the power source 16 and an electronic amplifier 22 which amplifies the signal from the pulse generator 12 for the electromagnet.

The version with the piston and the electric motor does not need an impulse generator or an amplifier. Here only the speed of rotation of the electric motor is controlled by a controller 21 .

The pressure wave will compress the air "elastic" in varying ways, but the fast, alternating pressure conditions can generate enough force to loosen the blockage.
