Abstract: An aerosol generator with electrical power conducting pins has a vibratable plate with apertures therein and an annular piezo. An annular support member supports the piezo and the vibratable plate. A first electrical power conducting pin engages directly with a first, top, surface of the piezo. A second electrical power conducting pin indirectly conducts electrical power to a second surface of the piezo, by contacting an extension tab. There is a film of cured epoxy adhesive on the tab. The aerosol generator avoids need for soldered joints for electrical contact, and the pins are conveniently mounted parallel to each on the same lateral and top side of the piezo and support member. The pins may have multi-point tips for particularly effective electrical contact.

Abstract: A photo-resist (21) is applied in a pattern or vertical columns having the dimensions of holes or pores of the aperture plate to be produced. This mask pattern provides the apertures which define the aerosol particle size, having up to 2500 holes per square mm. There is electro-deposition of metal (22) into the spaces around the columns (21). There is further application of a second photo-resist mask (25) of much larger (wider and taller) columns, encompassing the area of a number of first columns (21). The hole diameter in the second plating layer is chosen according to a desired flow rate.

Abstract: An aerosol generator (100) has a vibratable plate (1) with apertures therein and an annular piezo (2) which causes movement of the vibratable plate (1). An annular support member (3) supports the piezo (2) and the vibratable plate (1). A first electrical power conducting pin (10) engages directly with a first, top, surface of the piezo (2). A second electrical power conducting pin (11) indirectly conducts electrical power to a second surface of the piezo (2), by contacting an extension tab (103) of the support member (20), also on its top side. There is a film of cured epoxy adhesive on the tab (103), providing excellent gripping force between the pin (11) and the support (3). The aerosol generator (100) avoids need for soldered joints for electrical contact, and the pins are conveniently mounted parallel to each on the on the same lateral and top side of the piezo and support member. The pins may have multi-point tips (50) for particularly effective electrical contact.
Abstract translation: 气溶胶发生器（100）具有其中具有孔的可振动板（1）和引起可振动板（1）移动的环形压电体（2）。 环形支撑构件（3）支撑压电体（2）和可振动板（1）。 第一电力导电销（10）与压电体（2）的第一顶表面直接接合。 第二电力导电销（11）通过在支撑构件（20）的顶侧上接触支撑构件（20）的延伸片（103）来间接地将电力传导到压电体（2）的第二表面。 在片（103）上存在固化的环氧树脂粘合剂膜，在销（11）和支撑（3）之间提供优异的夹持力。 气溶胶发生器（100）避免了用于电接触的焊接接头的需要，并且销被方便地平行地安装在压电和支撑构件的同一横向和顶侧上。 引脚可以具有用于特别有效的电接触的多点尖端（50）。

Abstract: An aperture plate is manufactured by plating metal around a mask of resist columns having a desired size, pitch, and profile, which yields a wafer about 60 μm thickness. This is approximately the full desired target aperture plate thickness. The plating is continued so that the metal overlies the top surfaces of the columns until the desired apertures are achieved. This needs only one masking/plating cycle to achieve the desired plate thickness. Also, the plate has passageways formed beneath the apertures, formed as an integral part of the method, by mask material removal. These are suitable for entrainment of aerosolized droplets exiting the apertures.

Abstract: A method for aerosolising a liquid comprises the steps of: providing an aperture plate having at least 100 outlet holes per mm2; delivering liquid to the aperture plate; and vibrating the aperture plate to produce an aerosol. The viscosity of the liquid is in the range of from 1 to15 cP and the surface tension of the liquid is in the range of from 72 to 0.5 mN/m. The output rate of the generated aerosol is greater than 0.01 mL/min.

Abstract translation: 通过在具有期望的尺寸，间距和轮廓的抗蚀剂柱的掩模上镀覆金属来制造孔板，其产生约60μm厚度的晶片。 这大约是完全期望的目标孔板厚度。 继续进行电镀，使得金属覆盖在柱的顶表面上，直到达到所需的孔。 这只需要一个掩模/电镀周期来实现所需的板厚度。 此外，板具有形成在孔下方的通道，其形成为该方法的整体部分，通过掩模材料去除。 这些适合于夹带离开孔的雾化液滴。
