Description
技术领域 technical field
本发明涉及一种雾化装置，尤其涉及一种利用压电陶瓷进行液体雾化的装置。 The invention relates to an atomizing device, in particular to a device for atomizing liquid by using piezoelectric ceramics.
the
背景技术 Background technique
雾化片常用于日常生活中加湿、临床药物的雾化，在使用过程中，雾化片需长期与雾化液体接触，随着时间的推移，液体中的盐类等离子化合物会自然沉积于雾化微孔导致孔的直径变小甚至堵塞，影响雾化片的雾化效果。加之现有技术中，雾化片常采用焊接工艺直接将压电陶瓷片与金属膜片焊接，其结构如图1所示，在焊接过程中产生的高温对陶瓷片的性能具有一定的影响，而且更换陶瓷片需要再次焊开焊点，更换过程相当烦琐。由于金属膜片直接与陶瓷片焊接一起，当陶瓷片得电时其也处于带电状态成为一带电电极，液体中的离子化合物因电化反应吸附于雾化片的微孔区域造成的微孔的堵塞。而且，在临床药物的雾化过程液体中的化合物常因发生电解反应造成分子结构的破坏，导致药物失去其原有的药性。因此，雾化微孔在使用过程的堵塞及电解反应造成液体分子结构的破坏，一定程度上降低了雾化片的使用寿命，缩减了雾化片的使用范围，阻碍雾化片的市场化。 Atomizing tablets are often used for humidification in daily life and atomization of clinical drugs. During use, the atomizing tablet needs to be in contact with the atomized liquid for a long time. As time goes by, the salt plasma compounds in the liquid will naturally deposit on the mist. Minimizing the micropores will cause the diameter of the pores to become smaller or even blocked, which will affect the atomization effect of the atomization sheet. In addition, in the prior art, the atomizer usually uses welding technology to directly weld the piezoelectric ceramic sheet and the metal diaphragm. Its structure is shown in Figure 1. The high temperature generated during the welding process has a certain impact on the performance of the ceramic sheet. Moreover, the replacement of the ceramic sheet requires welding the solder joints again, and the replacement process is quite cumbersome. Because the metal diaphragm is directly welded to the ceramic sheet, when the ceramic sheet is electrified, it is also in a charged state and becomes a charged electrode. The ionic compound in the liquid is adsorbed on the micropore area of the atomized sheet due to electrochemical reaction, causing the micropore blockage . Moreover, during the atomization process of clinical drugs, the compounds in the liquid often cause damage to the molecular structure due to electrolytic reactions, causing the drugs to lose their original medicinal properties. Therefore, the blockage of the atomizing micropores during use and the destruction of the molecular structure of the liquid caused by the electrolytic reaction reduce the service life of the atomizing sheet to a certain extent, reduce the use range of the atomizing sheet, and hinder the marketization of the atomizing sheet.
