Description
Technical field
The utility model relates to ultrasonic unit field, particularly relates to piezoelectric ultrasonic probe apparatus.
Background technology
Ultrasonic sensor is the sensor utilizing hyperacoustic characteristic to develop.Ultrasound wave is the mechanical wave of a kind of vibration frequency higher than sound wave, is occurred to vibrate to produce by transducing wafer under the excitation of voltage, and it has, and frequency is high, wavelength is short, diffraction phenomenon is little, particularly good directionality, ray and the features such as direction propagation can be become.Ultrasound wave is very large to the penetrating power of liquid, solid, and especially in the opaque solid of sunlight, it can penetrate the degree of depth of tens meters.Ultrasound wave is encountered impurity or interphase and can be produced significantly to reflect to form and be reflected into echo, encounters live animal physical efficiency and produces Doppler effect.Scales based on Ultrasonic characteristics development is " ultrasonic sensor ", is widely used in the aspects such as industry, national defence, biomedicine.And the resolution of traditional ultrasonic sensor probe is accurate not, the requirement of precision detection can not be met.
Utility model content
The utility model will solve above technical matters, provides piezoelectric ultrasonic probe apparatus, improves the resolution of ultrasonic sensor probe.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions:
Piezoelectric ultrasonic probe apparatus; comprise betal can, insulation shell, lug plate, piezoelectric chip, diaphragm, damping block, conductive lever; diaphragm is positioned at the lateral surface of piezoelectric chip; insulation shell upper end is stuck in lug plate two ends and lower end is stuck in piezoelectric chip two ends; damping block is positioned at the cavity surrounded by insulation shell, lug plate, piezoelectric chip; conductive lever is connected with the middle part of the upper side of lug plate, and betal can is arranged on outside insulation shell.
Wherein, the interior lateral surface of piezoelectric chip is silver coated; Piezoelectric chip is rondelle, and its thickness and ultrasonic frequency are inversely proportional to.
Compared with prior art, the beneficial effects of the utility model are: the utility model adopts inside piezoelectric chip and fills absorption damping block in cavity, reduces the mechanical quality of piezoelectric chip, absorbs acoustic energy, limit hyperacoustic pulse width, improve the resolution of ultrasonic sensor probe.
