Description

Technical Field

[0001] The utility model relates to an oxygen sensor with a housing. Background Art

[0002] Additive manufacturing technology is an advanced manufacturing technology with distinct characteristics such as digital manufacturing, high flexibility and adaptability, direct CAD model driving, rapidity, and a rich variety of material types. Due to its unrestricted by the complexity of part shapes and the absence of any tooling and molds, its application range is very wide.

[0003] Selective Laser Melting (SLM) is one of the rapidly developing additive manufacturing technologies in recent years. It uses powder materials as raw materials and employs a laser to scan the cross-section of a three-dimensional entity layer by layer to complete prototype manufacturing.

[0004] During the working process of the above-mentioned additive manufacturing equipment, the oxygen content is a very important indicator. The commonly used sensor in the industry is a galvanic oxygen sensor. The oxygen sensor measures the oxygen potential in various scenarios using a ceramic sensitive element and calculates the corresponding oxygen concentration based on the chemical equilibrium principle. The oxygen sensor in this application has a long service life, is not easily interfered with and affected by carbon dioxide, has excellent chemical stability, and the sensor is applied to detect oxygen in various industries.

[0005] In the prior art, the sensor probe is generally made of nylon material, which is directly assembled with the stainless steel elbow of the equipment by means of threads. There is a wire for power supply on the sensor body, which is easily damaged in the exposed state, affecting the use of the sensor.

[0006] The direct assembly method makes the oxygen sensor probe prone to breakage and damage in the following situations:

[0007] 1. When subjected to external forces during the overhaul and maintenance process, it will be damaged;

[0008] 2. When the equipment is assembled, it is easy to touch the probe, and there is a risk of breakage under external forces;

[0009] 3. During the transportation of the equipment, there is a high probability that the stress of the exposed probe changes, with a risk of breakage.

[0010] 4. When the equipment is running, the resonance of the pipeline also poses a risk of probe breakage.

[0011] In summary, the sensor probe is easily damaged in the direct assembly method. Summary of the Utility Model
