微孔雾化元件属于一种压电换能元件，使用时功耗低，整机功率仅2瓦左右，广泛应用于美容、医疗等领域。采用它激电路可以使微孔雾化元件产生每秒10万次以上的面内机械振动，将供液腔或其它供液装置提供的液体雾化成1-9um的颗粒从金属基片的微孔区逸出从而实现雾化。但目前的微孔雾化元件存在以下问题：微孔雾化元件的振动频率较高，且振动过程中会产生热量，同时雾化片在无液体或液体很少时，会出现“干烧”现象，导致雾化片和其周边液体温度升高；而部分药液对温度极其敏感，高于热敏药液可承受的温度限值容易破坏其药性，这种状况给药厂及终端用户造成了很多应用上的难度。因此，能否设计一种实时测量雾化片温度的微孔雾化片以克服上述缺陷，是本领域技术人员有待解决的技术难题。The microporous atomizing element belongs to a piezoelectric transducer element, which has low power consumption during use, and the power of the whole machine is only about 2 watts. It is widely used in beauty, medical and other fields. The use of its excitation circuit can make the microporous atomizing element generate more than 100,000 in-plane mechanical vibrations per second, and atomize the liquid provided by the liquid supply chamber or other liquid supply devices into 1-9um particles from the micropores of the metal substrate. Zone escape to achieve atomization. However, the current microporous atomizing element has the following problems: the vibration frequency of the microporous atomizing element is high, and heat is generated during the vibration process, and the atomizing sheet will appear "dry burning" when there is no liquid or little liquid. This phenomenon causes the temperature of the atomized tablet and its surrounding liquid to rise; some liquid medicines are extremely sensitive to temperature, and their medicinal properties are easily damaged if the temperature is higher than the temperature limit that the heat-sensitive liquid medicine can withstand. many application difficulties. Therefore, it is a technical problem to be solved by those skilled in the art whether to design a microporous atomizing sheet that can measure the temperature of the atomizing sheet in real time to overcome the above-mentioned defects.
目前大多数厂家通过在雾化腔体增加测温传感器(NTC/PTC)进行测量雾化腔内液体的温度。但该方案存在缺陷，测温传感器测的液体温度与雾化片上的温度存在差距，反应速度慢，不能对反应雾化片上的温度进行实时反馈，可能存在雾化片上的温度已超过液体特性温度限值，破坏了液体特性，而此时测温传感器上显示的温度还未超出液体特性温度限值，导致不能有效的进行雾化控制。At present, most manufacturers measure the temperature of the liquid in the atomizing chamber by adding a temperature sensor (NTC/PTC) to the atomizing chamber. However, this scheme has defects. There is a gap between the temperature of the liquid measured by the temperature measuring sensor and the temperature on the atomizing sheet, the reaction speed is slow, and real-time feedback of the temperature on the atomizing sheet cannot be performed in real time. There may be a possibility that the temperature on the atomizing sheet has exceeded the characteristic temperature of the liquid. The limit value destroys the liquid characteristics, and the temperature displayed on the temperature sensor has not exceeded the liquid characteristic temperature limit at this time, resulting in the inability to effectively control the atomization.

在一个实施例中，微孔雾化片11包括：压电陶瓷片111、金属基片112以及第一电极113、第二电极114和第三电极115。In one embodiment, the microporous atomizing sheet 11 includes: a piezoelectric ceramic sheet 111 , a metal substrate 112 , and a first electrode 113 , a second electrode 114 and a third electrode 115 .
第一电极113和第二电极114与金属基片112电连接，第三电极115与压电陶瓷片111电连接。第一电极113和第三电极115与压电陶瓷片111、金属基片112和外部电路共同形成回路，用于驱动微孔雾化片11工作；第一电极113和第二电极114与金属基片112和外部电路共同形成回路，用于检测金属基片112的温度。此时，第二电极114为共用电极，即公共端(GND)。The first electrode 113 and the second electrode 114 are electrically connected to the metal substrate 112 , and the third electrode 115 is electrically connected to the piezoelectric ceramic sheet 111 . The first electrode 113 and the third electrode 115 form a circuit together with the piezoelectric ceramic sheet 111, the metal substrate 112 and the external circuit, and are used to drive the microporous atomizing sheet 11 to work; the first electrode 113 and the second electrode 114 are connected to the metal substrate. The chip 112 and the external circuit together form a loop for detecting the temperature of the metal substrate 112 . At this time, the second electrode 114 is a common electrode, that is, a common terminal (GND).
由于金属的导热性，及雾化片结构较小巧，金属基片112上的温度可以代表整个微孔雾化片11的温度。通过检测金属基片112上的电阻值，利用金属基片112材质的TCR特性，根据电阻值可以得出金属基片112上的温度，从而得到微孔雾化片11的温度。Due to the thermal conductivity of metal and the compact structure of the atomizing sheet, the temperature on the metal substrate 112 can represent the temperature of the entire microporous atomizing sheet 11 . By detecting the resistance value on the metal substrate 112 and using the TCR characteristic of the metal substrate 112, the temperature on the metal substrate 112 can be obtained according to the resistance value, thereby obtaining the temperature of the microporous atomizing sheet 11 .
其中，金属基片112为圆片，压电陶瓷片111为圆环，金属基片112的直径大于压电陶瓷片111的内径即可，本申请对此不做限定。The metal substrate 112 is a circular plate, the piezoelectric ceramic plate 111 is a ring, and the diameter of the metal substrate 112 may be larger than the inner diameter of the piezoelectric ceramic plate 111 , which is not limited in this application.
压电陶瓷片111的中心区域设置有通孔，金属基片112与压电陶瓷片111中心区域对应的区域设置有多个微孔。第一电极113与第二电极114间隔设置且与金属基片112电连接，只要满足可以检测金属基片112的电阻即可。第一电极113与第二电极114可以与金属基片112靠近压电陶瓷片111的表面接触，也可以与金属基片112远离压 电陶瓷片111的表面接触。第一电极113与金属基片112圆心的连线和第二电极114与金属基片112圆心的连线之间可以形成90度夹角或180度夹角等其他排布方式。由于第一电极113与第二电极114之间的距离越远，第一电极113与第二电极114之间的电阻值越大，越有利于提高检测精度；因而优选第一电极113与第二电极114设置在金属基片112直径方向的两个端点处，电阻的测量范围为16-30毫欧，采样精度较高，检测准确度较高。The central area of the piezoelectric ceramic sheet 111 is provided with a through hole, and the area of the metal substrate 112 corresponding to the central area of the piezoelectric ceramic sheet 111 is provided with a plurality of micro holes. The first electrode 113 is spaced apart from the second electrode 114 and is electrically connected to the metal substrate 112 as long as the resistance of the metal substrate 112 can be detected. The first electrode 113 and the second electrode 114 may be in contact with the surface of the metal substrate 112 close to the piezoelectric ceramic sheet 111, or may be in contact with the surface of the metal substrate 112 away from the piezoelectric ceramic sheet 111. The connection between the first electrode 113 and the center of the metal substrate 112 and the connection between the second electrode 114 and the center of the metal substrate 112 may form other arrangements such as a 90-degree angle or a 180-degree angle. Since the distance between the first electrode 113 and the second electrode 114 is farther, the resistance value between the first electrode 113 and the second electrode 114 is greater, which is more conducive to improving the detection accuracy; therefore, the first electrode 113 and the second electrode are preferably The electrodes 114 are arranged at the two end points in the diameter direction of the metal substrate 112, the resistance measurement range is 16-30 milliohms, the sampling accuracy is high, and the detection accuracy is high.
微孔雾化片11根据应用装置不同，会有不同的设计要求，可以将压电陶瓷片111设置为方形环或其他形状的环体，中间镂空部分用于暴露出金属基片112设置微孔的区域。压电陶瓷片111还可以为多段长方形板或其他形状，只需可以使金属基片112设有微孔的区域暴露出来，本发明对此不做限定。The microporous atomizing sheet 11 has different design requirements according to different application devices. The piezoelectric ceramic sheet 111 can be set as a square ring or a ring body of other shapes, and the hollow part in the middle is used to expose the metal substrate 112 and set the micropores Area. The piezoelectric ceramic sheet 111 may also be a multi-segment rectangular plate or other shapes, as long as the area of the metal substrate 112 with micropores can be exposed, which is not limited in the present invention.
根据应用装置不同，设置有微孔的金属基片112可以为方形片或三角形片等其他片状结构；压电陶瓷片111为环体，中间镂空部分根据金属基片112的形状结构设置相应的形状结构，实现金属基片112设置有微孔的区域可以通过压电陶瓷片111环体的镂空区域暴露。According to different application devices, the metal substrate 112 provided with the micro-holes can be other sheet-like structures such as a square sheet or a triangular sheet; The shape structure realizes that the area of the metal substrate 112 provided with the micro-holes can be exposed through the hollow area of the ring body of the piezoelectric ceramic sheet 111 .
进一步地，由于第一电极113与第二电极114之间的距离越远检测越准确，优选第一电极113与第二电极114设置在金属基片112上直线距离最远的线段的两个端点处。例如，当金属基片112为矩形，第一电极113与第二电极114间隔设置在矩形的对角线两端。Further, since the farther the distance between the first electrode 113 and the second electrode 114 is, the more accurate the detection is, it is preferable that the first electrode 113 and the second electrode 114 are arranged at the two end points of the line segment with the farthest straight line distance on the metal substrate 112 . place. For example, when the metal substrate 112 is a rectangle, the first electrode 113 and the second electrode 114 are arranged at two ends of the diagonal of the rectangle at intervals.
