Aerosol generator assembly

摘要

An aerosol generator assembly comprising a vibratable piezo ceramic body (2) having first and second opposing sides, an aperture (o) defined in the vibratable body and extending through the body from the first side to the second side and having a layer of electrical contact material on each side of the vibratable body, the vibratable body being vibratable by application of an electrical signal thereto; a vibratable member (1) with pores defined therein, the vibratable member mounted across the aperture; and an electrical contact material free-zone (4) is provided on at least one side of the body about the aperture, characterized in that the electrical contact material free-zone and the vibratable member are dimensioned so that the vibratable member is mountable directly onto the vibratable body on top thereof within the electrical contact material free-zone such that a gap area free of electrode contact material is formed between the terminating edge of the electrical contact material and the periphery of the vibratable member.

1. An aerosol generator assembly comprising:
a vibratable piezo ceramic body having first and second opposing sides, an aperture defined in the vibratable piezo ceramic body and extending through the body from the first side to the second side and having a layer of electrical contact material on each side of the vibratable piezo ceramic body, the vibratable piezo ceramic body being vibratable by application of an electrical signal thereto; a vibratable member with pores defined therein, the vibratable member mounted across the aperture; and an electrical contact material free-zone is provided on at least one side of the vibratable piezo ceramic body about the aperture, wherein the electrical contact material free-zone and the vibratable member are dimensioned so that the vibratable member is mountable onto the vibratable piezo ceramic body on top thereof within the electrical contact material free-zone such that a gap area free of the layer of electrical contact material is formed between the terminating edge of the layers of electrical contact material and the periphery of the vibratable member, thus electrically insulating the terminating edge of the electrical contact material from the vibratable member.
