Description

Technical Field

[0001] The utility model relates to the technical field of piezoelectric sensing, in particular to a piezoelectric ceramic sensing device. Background Art

[0002] Piezoelectric ceramics are a type of information functional ceramic material that can convert mechanical energy and electrical energy into each other. Piezoelectric ceramic sheets are widely used. In conventional designs, external sounds are mostly transmitted to piezoelectric ceramic sheets through the shell and air, so that the piezoelectric ceramic sheets are vibrated by the sound waves and stimulate the sensing current signal.

[0003] For example, a Chinese patent with publication number CN217930535U discloses a high-sensitivity piezoelectric ceramic vibration sensor device, including a shell, a piezoelectric ceramic sheet is arranged in the shell, the piezoelectric ceramic sheet is horizontally installed in the shell, the edge of the piezoelectric ceramic sheet is fixed to the inner wall of the shell, and the sensing area of ​​the piezoelectric ceramic sheet is empty above and below; the vibration sensor device also includes a weight, which is placed above the center of the piezoelectric ceramic sheet.

[0004] The technical solution recorded in this proposal greatly improves the sensitivity of piezoelectric ceramics to sound sensing by designing a heavy hammer technical solution, thereby achieving long-distance and accurate measurement of sounds with long distances and low energy, and realizing precise long-distance sound detection such as pipe leakage, power grid leakage, and noise pollution. However, when this solution is in use, it is placed on a metal water supply pipe through magnetic attraction and does not have a fixing function. When the pipe vibrates, the product will shift and move to the bottom of the pipe. At this time, the product will flip over, and the heavy hammer will always be away from the piezoelectric ceramic due to gravity, causing the sensor to fail.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a piezoelectric ceramic sensor device is provided to achieve a more practical purpose. Utility Model Content
