本发明属于模拟吸烟技术领域，特别地，涉及一种超声雾化片、雾化器及气溶胶发生装置。The invention belongs to the technical field of simulated smoking, and in particular relates to an ultrasonic atomizing sheet, an atomizer and an aerosol generating device.
背景技术Background technique

The atomizer can heat and atomize the aerosol-forming substrate stored in the atomizer under the electric drive of the power supply device. For the user to smoke to achieve the effect of simulating smoking.
当前，雾化器的超声雾化片的结构中，一般是在压电陶瓷上设置电极层，并将引线焊接于压电陶瓷的陶瓷区域内(包括引线焊接于压电陶瓷上和引线焊接于电极层上的情形)，通过连接电源的引线向压电陶瓷施加电压，以使压电陶瓷产生谐振。在超声雾化片工作时，由于引线是直接焊接在压电陶瓷的陶瓷区域内，容易出现压电陶瓷在焊点处受力明显增大的现象，不仅导致压电陶瓷振动不均衡，影响压电陶瓷振动性能，而且在受力不均衡的情形下，还会造成压电陶瓷内部暗裂或直接破裂。At present, in the structure of the ultrasonic atomizing sheet of the atomizer, the electrode layer is generally arranged on the piezoelectric ceramic, and the lead wire is welded in the ceramic region of the piezoelectric ceramic (including the lead wire welded on the piezoelectric ceramic and the lead wire welded on the piezoelectric ceramic. On the electrode layer), a voltage is applied to the piezoelectric ceramics through the lead wire connected to the power supply to make the piezoelectric ceramics resonate. When the ultrasonic atomizer is working, because the lead wire is directly welded in the ceramic area of the piezoelectric ceramic, it is easy to appear that the force of the piezoelectric ceramic at the welding point increases significantly, which not only causes the vibration of the piezoelectric ceramic to be unbalanced, but also affects the pressure of the piezoelectric ceramic. The vibration performance of electric ceramics, and in the case of unbalanced force, it will also cause dark cracks or direct cracks inside the piezoelectric ceramics.

本发明实施例中的超声雾化片、雾化器及气溶胶发生装置，超声雾化片结构中，通过在第一电极层上设置第一金属片，在第一金属片上设置伸出压电陶瓷片所在的区域的第一极耳，同时在第二电极层上设置第二金属片，并在第二金属片上设置伸出压电陶瓷片所在的区域的第二极耳。如此，仅需将电连接于电源装置的两根引线，分别焊接于第一极耳和第二极耳伸出压电陶瓷片所在区域的部分，就可以通过电源装置向压电陶瓷片的第一面和第二面分别施加电压。则在超声雾化片工作时，由于第一极耳和第二极耳分别伸出压电陶瓷片所在的区域，可保证焊点均位于压电陶瓷片的陶瓷区域外，能够消除压电陶瓷在焊点处受力明显增大而存在的受力不均衡的缺陷，不仅避免压电陶瓷在焊点处受力不均衡而影响压电陶瓷振动性能，而且可有效防止因压电陶瓷受力不均衡而造成压电陶瓷内部暗裂或直接破裂的问题出现。In the ultrasonic atomizing sheet, atomizer and aerosol generating device in the embodiment of the present invention, in the structure of the ultrasonic atomizing sheet, the first metal sheet is arranged on the first electrode layer, and the extending piezoelectric device is arranged on the first metal sheet.

Voltages are applied to one side and the second side separately. Then, when the ultrasonic atomizing sheet is working, since the first tab and the second tab extend out of the area where the piezoelectric ceramic sheet is located, it can be ensured that the solder joints are all located outside the ceramic area of the piezoelectric ceramic sheet, which can eliminate the piezoelectric ceramic The defect of unbalanced force caused by the obvious increase of the force at the solder joint not only avoids the impact on the vibration performance of the piezoelectric ceramic due to the unbalanced force at the solder joint, but also effectively prevents the piezoelectric ceramic from being subjected to force. The problem of internal cracks or direct cracks in piezoelectric ceramics due to unbalance occurs.

The ultrasonic atomizing sheet provided by the embodiment of the present invention is suitable for an atomizer of an aerosol generating device, and the aerosol generating device includes an atomizer and a power supply device (not shown) electrically connected to the atomizer. When in use, the power supply device is used to provide electric energy to the ultrasonic atomizing sheet of the nebulizer. It can convert electrical energy into mechanical energy, and undergo repeated deformation to generate vibration. During the vibration of the piezoelectric ceramic sheet 1 , the aerosol-forming matrix can be squeezed out from the micropores, thereby forming a mist of fine particles.
请结合参阅图1、图2和图6，本发明实施例提供的超声雾化片包括压电陶瓷片1、第一电极层2、第二电极层3、第一金属片4和第二金属片5，压电陶瓷片1的居中位置贯穿设置有通孔11，压电陶瓷片1沿通孔11轴向的两端分别具有第一面12和第二面13。为了向压电陶瓷片1的第一面12和第二面13分别施加电压，以使得压电陶瓷片1产生振动，需要在压电陶瓷片1的第一面12上设置第一电极层2，在压电陶瓷片1的第二面13上设置第二电极层3。具体地，第一电极层2层叠设置于压电陶瓷片1的第一面12上，第一金属片4设于第一电极层2背离压电陶瓷片1的一面上，第一金属片4与第一电极层2电性相连。第二电极层3层叠设置于压电陶瓷片1的第二面13上，第二金属片5设于第二电极层3背离压电陶瓷片1的一面上，第二金属片5与第二电极层3电性相连，第二金属片5对应通孔11的位置开设有微孔。请结合参阅图2、图4和图5，第一金属片4上设有用于焊接引线30或用于供顶针抵接的第一极耳6，第二金属片5上设有用于焊接引线30或用于供顶针抵接的第二极耳7，第一极耳6的至少部分伸出压电陶瓷片1所在的区域，第二极耳7的至少部分伸出压电陶瓷片1所在的区域。则在使用时，仅需将两根引线30分别焊接于第一极耳6和第二极耳7上，就可以通过电源装置向压电陶瓷片1的第一面12和第二面13分别施加电压。这样，在超声雾化片工作时，由于第一极耳6和第二极耳7分别伸出压电陶瓷片1所在的区域，可保证焊点40均位于压电陶瓷片1的陶瓷区域9(陶瓷区域9是指图2中虚线内的区域)外，也就是说引线30无需直接焊接在压电陶瓷片1的陶瓷区域9内，从而消除了压电陶瓷在焊点40处受力明显增大而受力不均衡的缺陷，不仅避免压电陶瓷在焊点40处受力不均衡而影响压电陶瓷振动性能，而且可有效防止因压电陶瓷受力不均衡而造成压电陶瓷内部暗裂或直接破裂的问题出现。可以理解地，在通过顶针抵接于第一极耳6和/或第二极耳7上时，由于第一极耳6和第二极耳7分别伸出压电陶瓷片1所在的区域，可保证触点均位于压电陶瓷片1的陶瓷区域9外，也同样能够消除了压电陶瓷在焊点40处受力明显增大而受力不均衡的缺陷。Please refer to Fig. 1, Fig. 2 and Fig. 6.

In some embodiments, the piezoelectric ceramic sheet 1 is circular, and the inner ring of the piezoelectric ceramic sheet 1 encloses to form a through
请结合参阅图1、图4和图6，在其中一些实施例中，第一金属片4为第一环形保护片，第一环形保护片覆设于第一电极层2背离压电陶瓷片1的一面上，也就是说，第一环形保护片与第一电极层2的形状与尺寸完全相同，以充分保证第一环形保护片与第一电极层2完全重叠设置。当然，第一环形保护片与第一电极层2的形状与尺寸也可以不相同。可以理解地，第一环形保护片即第一金属片4，可以是但不限于不锈钢或钛。这样，通过第一环形保护片代替第一电极层2上的玻璃釉质保护层，又可以同时兼顾导电且同时保持了压电陶瓷片1的第一面12的完整性，有利于压电陶瓷片1的第一面12受力均衡。为了使得第一极耳6不在压电陶瓷片1所在的区域内，以保证引线30与第一极耳6的焊点40不在压电陶瓷片1所在的区域内，将第一极耳6设于第一环形保护片的外周，且第一极耳6沿通孔11的径向延伸，使得第一极耳6在垂直方向上的投影与压电陶瓷片1在垂直方向上的投影不重合，可保证焊点40均位于压电陶瓷片1的陶瓷区域9外，能够消除压电陶瓷在焊点40处受力明显增大而存在的受力不均衡的缺陷，不仅避免压电陶瓷在焊点40处受力不均衡而影响压电陶瓷振动性能，而且可有效防止因压电陶瓷受力不均衡而造成压电陶瓷内部暗裂或直接破裂的问题出现。可以理解地，请结合参阅图4，在其中一些实施例中，第一极耳6可以与第一环形保护片即第一金属片4一体成型。也就是说，当第一环形保护片即第一金属片4为不锈钢或钛等金属片时，可以是在第一环形保护片即第一金属片4延展出第一极耳6。Please refer to FIG. 1 , FIG. 4 and FIG. 6 in conjunction.
