The face filling ultrasonic detector provided by the embodiment is used for enabling the detection probe 2 to abut against a face, enabling the ultrasonic transducer unit in the detection probe 2 to emit ultrasonic waves and receive echo signals, enabling the echo signals to form an ultrasonic image of face tissues through the imaging module, and judging whether the filling material exists in the face or not because the filling material in the face and the reflection effect and the absorption rate of the face tissues to the ultrasonic waves are different. The rolling protrusions are arranged on the abutting surfaces, so that adverse effects of displacement, deformation and the like caused by extrusion of fillers in the human face when the human face to be detected is detected are avoided. The whole detection process is simple, visual and convenient.
A face filling ultrasonic detector comprises a shell 1 including a holding part 11, and a detection probe 2 arranged at one end far away from the holding part 11. At the position of the holding part 11, an arc shape is designed to be convenient for holding by hand, and at the position of the holding part 11, an anti-skid stripe or an anti-skid rubber pad can be arranged.
The detection probe 2 is detachably connected with the housing 1, for example, the detection probe 2 is connected with the end of the housing 1 by screw threads or by a snap. When the device is not used at ordinary times, the detection probe 2 is sleeved with a protective cover to avoid invasion and pollution of dust and sundries; when the detector is required to be used, the protective cover is taken down for normal use. The outer side of the detection probe 2 is provided with an abutting surface which can be fully contacted with a human face; an ultrasonic transducer unit is arranged on the inner side of the detection probe 2.
The ultrasonic transducer unit includes a generating unit for generating ultrasonic waves and a receiving unit for receiving echo signals of the ultrasonic waves.
The ultrasonic wave is electromagnetic wave with frequency higher than 20000 Hz and has strong penetrating power.
An ultrasonic transducer is a device capable of converting high-frequency electric energy into mechanical energy, and generally has a magnetostrictive type and a piezoelectric ceramic type. For example, an ultrasonic transducer may use a piezoelectric ceramic resonant at an ultrasonic frequency, and the piezoelectric effect of the material converts an electrical signal into mechanical vibration (ultrasonic waves).
The ultrasonic transducer unit includes an ultrasonic generating circuit that converts an electric signal into mechanical vibration (ultrasonic wave) and an ultrasonic receiving circuit that converts the mechanical vibration (ultrasonic wave) into an electric signal. The ultrasonic receiving circuit may generally employ a monostable ultrasonic receiving circuit or a bistable ultrasonic receiving circuit.
A PCB is arranged in the shell 1 and is electrically connected with the ultrasonic transducer unit; the PCB comprises an imaging module, and the imaging module obtains a visible image of the human face tissue property and structure by receiving and processing the echo carrying the human body tissue or structure property characteristic information according to the echo signal received by the receiving unit.
A detection system is integrated on a PCB of the ultrasonic detector and comprises a scanning module, an analysis module, a judgment module and a display module, wherein the scanning module carries out ultrasonic scanning on a human face and acquires an ultrasonic scanning image in the process of detecting the human face back and forth by the ultrasonic detector. The analysis module is used for carrying out noise reduction processing on the acquired ultrasonic scanning image, the noise of the ultrasonic image is more generally, and the definition and the distinguishability of the image can be greatly enhanced after the noise reduction processing. Denoising can generally be performed using a median filtering algorithm or a wavelet threshold denoising algorithm. The principle of median filtering is to replace the value of a point in a digital image or sequence of numbers with the median of the values of the points in the neighborhood of the point. The wavelet threshold denoising step can be divided into three steps: first, a wavelet and a level of wavelet decomposition (the level of the optimal wavelet decomposition is 3) are selected, a wavelet decomposition processing operation is performed on a signal, and a coefficient obtained after decomposition is calculated. Then, a proper threshold value and a proper threshold value function are selected, and the coefficients of each layer are quantized by the selected function. And finally, calculating the wavelet reconstruction of the signal according to the low-frequency coefficient obtained from the F-th layer of the wavelet decomposition and the high-frequency coefficient obtained after the quantization from the first layer to the F-th layer. Relatively speaking, the wavelet threshold denoising is to select multiple thresholds for denoising at multiple levels of the decomposed scales, so that the processing effect is better and the image is clearer.
The judging module is used for calling a preset model algorithm to judge whether the ultrasonic scanning image subjected to noise reduction processing has fillers. For the preset model algorithm of the judging module, the characteristic comparison between the ultrasonic image in the common face and the ultrasonic image with the filler in the face can be carried out for a limited number of times, and the algorithm adjustment is carried out, so that whether the filler exists in the face is judged. And the display module is used for extracting and displaying the image containing the filling material on the display screen 3 of the ultrasonic detector or an external display thereof.
When the ultrasonic detector detects that the filling is in the face to be detected through the scanning module, the analysis module and the judgment module, the buzzer sends out a prompt tone of 'tic' or sends out a prompt signal in a twinkling mode through the LED lamp, so that the ultrasonic detector can detect whether the filling is in the face to be detected, and the ultrasonic image of the face does not need to be displayed. When the condition of the filling material inside the face needs to be further known, or the condition of the filling material inside the face needs to be known more intuitively, it is more effective to make the ultrasonic image of the face pass through the display screen 3 or an external display.
The ultrasonic imaging can obtain the image space resolution better than 1 meter in the detection depth range of nearly twenty centimeters. The ultrasonic imaging can realize high-speed real-time imaging, can observe moving organs and save the inspection time.
The reflection effect and the absorption rate of the ultrasonic wave by the human tissue and the filler are different, so that whether the filler exists in the human face or not and the position of the area where the filler is located can be observed.
Be equipped with display screen 3 on casing 1 for 2 butt surfaces of test probe for show the ultrasonic image of human face tissue and structure, the inside filler that has of human face that awaits measuring can be judged to the inspection personnel's accessible ultrasonic image.
The abutting surface of the detection probe 2 is provided with the rolling bulge, so that adverse effects such as displacement and deformation caused by extrusion of fillers in the human face during detection of the human face to be detected can be avoided.
For example, the rolling lobe includes a plurality of balls each having a coupling hole provided in a diameter direction thereof and a fixing member provided on the abutting surface, the fixing member being coupled with the balls through the coupling holes, the balls being rotatable around the fixing member. When the human face is supported to the butt face of testing personnel with ultrasonic detector, when promoting ultrasonic detector through portion 11 that grips, the ball rotates around the mounting, avoids pushing the face of the personnel that await measuring with the indulging and causes the damage.
For example, the rolling protrusion may include a plurality of beads and a plurality of rotating shafts, wherein a plurality of beads are arranged on each rotating shaft in series, and the beads on the plurality of rotating shafts are adjacent to each other to form the abutting surface. When the detection personnel push the ultrasonic detector through the holding part 11, the beads roll on the rotating shaft, and the damage caused by the fact that the face of the detection personnel is extruded crudely is avoided.
The abutting surface can be made of silica gel or plastic materials with certain elasticity, and the abutting surface can be sunken and buffered if excessive force is applied in the detection process; after the abutting surface leaves the human face, the concave abutting surface can automatically rebound and reset.
Preferably, a plurality of springs are arranged on the inner side of the elastic abutting surface to help the abutting surface to rebound and reset. Through the arrangement of the elastic abutting surface, the adverse effects of displacement, deformation and the like caused by extruding the fillers in the human face are further avoided.

Under the continuous working mode, the ultrasonic transducer continuously emits ultrasonic waves; in the pulse working mode, the ultrasonic transducer emits ultrasonic waves at regular intervals. Different modes of operation may produce different cosmetic effects. When the control unit adjusts the power of the ultrasonic transducer, the power can be divided into weak, medium and strong gears, and a timer can be adopted to control the working time of the ultrasonic transducer.
The control unit is electrically connected with an external oscillation circuit, and the external oscillation circuit comprises a crystal oscillation tube X and two oscillation capacitors C1 and C2 and is used for protecting the work of the control unit.
A power supply unit is arranged in the shell 1 and supplies power to the PCB and the ultrasonic transducer unit. The power supply unit may employ a secondary lithium battery, such as 18650 lithium battery. A charging interface is provided at an end of the housing 1 for charging the power supply unit.
