Preheating device for ultrasonic probe

Abstract

The invention relates to the technical field of ultrasonic probes and discloses a preheating device for an ultrasonic probe. The preheating device for the ultrasonic probe comprises a shell, a ball body is placed on the inner bottom wall of a fixed seat, a baffle is movably inserted into the bottom portion of the fixed seat, a button switch is arranged in the fixed seat and at the right side of the baffle, ejector rods which are uniformly distributed are movably hinged on the outer side of a rotating plate I, a rotating plate II rotatably sleeves the outer side of a fixed shaft, a collision plate is fixedly connected on the right side of the rotating plate, and a rack plate is fixedly connected on the right side of a thermal deformation material. The preheating device for the ultrasonic probe confirms whether the preheating is completed or not by detecting the temperature in the probe, the temperature in the probe changes all the time when preheating, the thermal deformation material is heated constantly and continues to deform to drive the rotating plate I to rotate all the time, the baffle keep off the ball body all the time, as long as the correct working temperature is reached,a state with a constant temperature can be generated in the probe to confirm the completion of preheating, and therefore, the preheating effect is better.

Description

technical field [0001] The invention relates to the technical field of ultrasonic probes, in particular to preheating equipment for ultrasonic probes. Background technique [0002] Ultrasonic sensors can only be configured and operated after warming up, and there will be warm-up drift during the process from cold start to normal operating temperature, that is, when a sensor is powered on, the temperature of a single component will cause the surrounding air and All other components heat up, causing temperature fluctuations, until all components have stabilized at the correct operating temperature before testing, otherwise the accuracy of the measurement will be affected. [0003] At present, the probe of the ultrasonic sensor generally adopts a timing method to preheat. After the probe is preheated for a period of time, it is considered that the probe has reached the correct working temperature. However, there are still some problems in this method. In the actual use process,...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a preheating device for an ultrasonic probe, which can be used to confirm the completion of preheating when the temperature in the probe reaches the correct temperature for a short period of time without changing the temperature. The heating time is too long or too short, and the preheating effect is better. It solves the problem that the general ultrasonic probe adopts the method of timing preheating. Because the initial temperature of the probe is different, the temperature of the probe is too high or the temperature is too high after the preheating. too low problem
