Description
Sprühkopf für Aerosolzerstäuber
Zur Applikation von Pharmazeutika finden insbesondere in der zahnärztlichen Praxis mit Sprükopf versehene Zerstäuber Verwendung, bei denen der Sprühkopf mit einem Düsenrohr ausgerüstet ist.
Die Anbringung des meist gewinkelten Düsenrohres muss folgenden Anforderungen genügen. Das Düsenrohr muss um seine Achse drehbar, zwecks Sterilisation leicht abnehmbar und in die Bohrung dicht eingepasst sein. Ausserdem muss die Einstecktiefe begrenzt sein.
Bei bekannten Geräten wird die Einstecktiefe durch Anbringung eines Ringwulstes oder eines Anschlages auf dem Düsenrohr begrenzt. Im ersten Fall ist die Befestigung unzureichend, im zweiten Fall lässt besonders bei mehrmaligem Wechsel des Düsenrohres die Dichtigkeit zu wünschen übrig. Ausserdem führt die Anbringung einer Begrenzungsvorrichtung zu einer Verteuerung des Düsenrohres.
Es wurde nun gefunden, dass die obengenannten Anforderungen in einfacher Weise erfindungsgemäss dadurch erfüllt werden können, dass der Sprühkopf eine-warzenförmige Ausstülpung trägt, durch die eine zur Aufnahme eines Sprührohres dienende radiale, nach innen leicht konisch verlaufende Bohrung führt, wobei die Einstecktiefe durch eine Verengung der Bohrung begrenzt ist, und zwecks Aufsteckens auf den Ventilschaft mit einer axialen Bohrung versehen ist.
Die erfindungsgemässe Ausführung bietet den Vorteil, dass durch die konische radiale Bohrung jederzeit eine dichte Verbindung zwischen Sprühkopf und Sprührohr gewährleistet und die Verwendung eines einfachen Sprührohres möglich ist. Durch die warzenförmige Ausstülpung wird die Führung des Sprührohres verlängert und damit dessen Befestigung gesichert.
Die Abbildung zeigt eine Ausführungsform des Erfindungsgegenstandes im Querschnitt.
PATENTANSPRUCH
Sprühkopf für Aerosolzerstäuber, dadurch gekennzeichnet, dass der Sprühkopf (1) eine warzenförmige Ausstülpung (2) trägt, durch die eine zur Aufnahme eines Sprührohres (3) dienende radiale, nach innen leicht konisch verlaufende Bohrung (4) führt, wobei die Einstecktiefe durch eine Verengung (5) der Bohrung begrenzt ist, und zwecks Aufstekkens auf den Ventilschaft mit einer axialen Bohrung (6) versehen ist.

Spray head for aerosol atomizers
For the application of pharmaceuticals, especially in the dental practice, atomizers provided with spray heads are used, in which the spray head is equipped with a nozzle tube.
The attachment of the mostly angled nozzle tube must meet the following requirements. The nozzle tube must be rotatable around its axis, easily removable for sterilization and fitted tightly into the bore. In addition, the insertion depth must be limited.
In known devices, the insertion depth is limited by attaching an annular bead or a stop on the nozzle tube. In the first case the fastening is inadequate, in the second case the tightness leaves something to be desired, especially when the nozzle tube is changed several times. In addition, the attachment of a limiting device makes the nozzle pipe more expensive.
It has now been found that the above-mentioned requirements can be met in a simple manner according to the invention in that the spray head has a wart-shaped protuberance through which a radial, slightly conical bore serving to accommodate a spray tube leads, the insertion depth being through a Narrowing of the bore is limited, and is provided with an axial bore for the purpose of being pushed onto the valve stem.
The embodiment according to the invention offers the advantage that the conical radial bore ensures a tight connection between the spray head and spray tube at all times and the use of a simple spray tube is possible. Due to the wart-shaped protuberance, the guidance of the spray tube is lengthened and thus its fastening is secured.
The figure shows an embodiment of the subject matter of the invention in cross section.
