Description

Die Erfindung bezieht sich auf einen piezoelektrischen Schwinger aus Keramik, der zum Beschälten eines flüssigen Gutes dient. Gemäß der Erfindung ist der Schwinger als Durchlauftrichter ausgebildet und mit einem insbesondere an seinem Auslaufende angeordneten Filter versehen. Hierdurch ergibt sich der große Vorteil, daß unmittelbar nach einer Beschallung, die beispielsweise zur Koagulierung von in. einer Flüssigkeit enthaltenen ίο Teilchen geführt hat, ein Filterprozeß angeschlossen werden kann, so daß jegliche Verluste der durch das Besahallen erzielten Wirkung vermieden werden. Außerdem kann ein solcher Schwinger zum Herstellen von aufzubrühenden Getränken, wie Kaffee· und Tee, vorteilhaft Anwendung finden.The invention relates to a piezoelectric oscillator made of ceramic, which is used for peeling serves a liquid good. According to the invention, the vibrator is designed as a flow hopper formed and provided with a filter arranged in particular at its outlet end. Through this there is the great advantage that immediately after a sound system, for example for Coagulation of ίο particles contained in a liquid has led to a filter process being connected can be so that any loss of the effect achieved by the insulting is avoided. In addition, such a vibrator for making beverages to be brewed, such as Coffee · and tea, find beneficial use.

Der als Durchlauftrichter zu verwendende piezoelektrische Schwinger kann auch in Form eines Kegelstumpfes ausgebildet sein und aus einzelnen ebenen piezoelektrischen Platten zusammengesetzt sein.The piezoelectric oscillator to be used as a flow hopper can also be in the form of a Be formed truncated cone and composed of individual flat piezoelectric plates be.

An sich könnte auch ein. zylindrischer Durchlaufschwingkörper mit einem Filter baulich kombiniert werden, doch bietet nur die Trichterf orm den Vorteil, daß die zum Filter strömende Flüssigkeit auf Grund des sich verengenden Durchlaufquerschnittes mit stetig wachsender Intensität beschallt wird. Es ist auch keineswegs erforderlich, das Filter als Abschluß in den trichterförmigen Schwingkörper anzuschließen, sondern das Filter kann beispielsweise für Sonderzwecke auch an irgendeiner anderen Stelle im Durchlaufweg des Sahwingkörpers angeordnet werden. So können auch mehrere Filter innerhalb des Durcihlaufschwingköipeirs vorgesehen werden.In itself could also be a. cylindrical vibrating body can be structurally combined with a filter, but only the funnel shape offers Advantage that the liquid flowing to the filter due to the narrowing flow cross-section is irradiated with constantly increasing intensity. It is also by no means necessary to connect the filter as a conclusion in the funnel-shaped oscillating body, but the filter can, for example, for special purposes at any other point in the flow path of the Sahwing body are arranged. So can also several filters within the Durcihlaufschwingköipeirs are provided.

Piezoelektrische Schwinger von trichterförmiger Gestalt ohne Filter sind nicht Gegenstand des Patents.Piezoelectric vibrators with a funnel shape without a filter are not part of the Patents.

In der Zeichnung ist ein Ausführungsbeispiel dargestellt. Der Schwingkörper 3 gemäß dem Ausführungsbeispiel hat die Form eines sich nach unten verjüngenden Kegefetumpfes; er ist also trichterförmig ausgebildet. Am unteren Ende des Sahwingkörpers ist im vorliegenden Fall noch ein Filter 4 angeordnet, so daß die Anordnung zum gleichzeitigen. Beschallen und Filtern verwendet werden kann.An exemplary embodiment is shown in the drawing. The vibrating body 3 according to the embodiment has the shape of a truncated cone that tapers downwards; so he is funnel-shaped. At the lower end of the Sahwing body is still a in the present case Filter 4 arranged so that the arrangement for simultaneous. Sonication and filtering used can be.
