Description

Technical Field

[0001] The utility model belongs to the technical field of gas sensors, and in particular relates to a multi-fusion sensor detection rod. Background Art

[0002] In some production environments, such as winemaking, fermentation takes place, and the environment within the fermentation tanks requires strict control. Therefore, real-time monitoring of the fermentation tank environment is crucial. Environmental quality is typically measured by the concentrations of substances such as oxygen, carbon dioxide, and ethanol. Currently, most infrared and laser-based gas sensors on the market fail to function properly in environments with humidity exceeding 95%. However, these gas sensors, designed to detect oxygen, carbon dioxide, and alcohol levels in fermentation tanks, often operate in environments with humidity levels above 98%. This often results in these sensors experiencing abnormalities and malfunctions. Furthermore, currently common methods for removing moisture, such as electrical heating, are feasible when energy consumption is not a concern, but become unsuitable when low power consumption is a concern. Therefore, there is an urgent need to design a low-power gas sensor suitable for high-humidity environments. Summary of the Invention

[0003] The purpose of the present utility model is to overcome the deficiencies in the prior art and provide a multi-fusion sensor detection rod. By making structural improvements to the packaging structure of the gas sensor, the gas sensor component is breathably and dehumidified packaged, so that it can achieve power-free dehumidification, overcome the influence of high humidity in a high-humidity working environment, and work normally to detect multiple gases, thereby improving the application range and measurement accuracy of the gas sensor.

[0004] In order to achieve the above-mentioned purpose, the present invention is implemented by adopting the following technical solutions.

[0005] The utility model provides a multi-fusion sensor detection rod, comprising: a sensor packaging structure and a peripheral structure shell;

[0006] The sensor packaging structure includes a breathable and dehumidifying structure and a gas sensor component packaged in the breathable and dehumidifying structure;

[0007] The peripheral structure shell is sleeved on the outside of the sensor packaging structure and is used to perform pre-liquid water isolation treatment on the gas to be measured entering the interior of the sensor packaging structure.

[0008] The sensor packaging structure is obtained by packaging the gas sensor in the gas-permeable and dehumidifying structure, the gas to be measured entering the gas-permeable and dehumidifying structure is dehumidified, and the packaged sensor packaging structure is loaded into the peripheral structure shell, so that the sensor packaging structure is isolated from liquid water, and the gas-permeable and dehumidifying structure is prevented from being affected by high humidity to affect the normal work of the gas sensor therein. The gas sensor is completely improved in structure, and dehumidification is realized without power consumption. The gas can be normally detected in a high-humidity working environment.

[0009] Optionally, the gas sensor assembly comprises two gas sensors of different types of measured objects, and the gas sensors are respectively located at the ends of the gas-permeable and dehumidifying structure, and the detection openings of the two gas sensors are placed opposite to each other.

[0010] Optionally, the gas-permeable and dehumidifying structure comprises a gas-permeable shell and a dehumidifying object.

[0011] The gas-permeable shell has a sensor compartment and a dehumidifying object compartment, the sensor compartments are respectively located at the two ends of the gas-permeable shell, and the dehumidifying object compartment is located between the two sensor compartments.

[0012] The two gas sensors are respectively located inside the two sensor compartments, and the dehumidifying object is filled in the dehumidifying object compartment to dry the water in the gas to be measured.

[0013] The internal space of the gas-permeable shell is filled with the dehumidifying object, so that the gas entering the internal space of the gas-permeable shell is dehumidified before contacting the gas sensor, and the gas sensor can normally detect the low-humidity gas to be measured.

[0014] Optionally, the internal shape of the gas-permeable shell is adapted to wrap the gas sensor and the dehumidifying object.

[0015] Optionally, the gas-permeable shell is a heat-shrinkable tube with gas holes on the surface after being heated and shrunk.

[0016] Optionally, the dehumidifying object is a desiccant.

[0017] The desiccant is selected as the dehumidifying object in the packaging structure, which can dry and dehydrate the gas entering the internal space of the gas-permeable shell, and provide flow gaps for the dehydrated gas, so that the detection openings of the gas sensors at the two ends of the gas-permeable shell can contact the low-humidity gas after dehydration.

[0018] Optionally, the peripheral structure shell is provided with gas holes for balancing the gas environment inside and outside the peripheral structure shell.

[0019] The inner surface of the peripheral structure shell at the gas hole is covered with a waterproof and gas-permeable film.

[0020] The waterproof and breathable film is covered on the air hole of the peripheral structure shell, so that the gas with high humidity is dehydrated once before entering the interior of the peripheral structure shell, thereby avoiding the situation that the dehydration capacity of the desiccant in the sensor packaging structure cannot bear a large amount of liquid and the normal work of the gas sensor is affected.

[0021] Optionally, the outer surface of the peripheral structure shell where the air hole is arranged is covered with a protective net.

[0022] Optionally, the multi-fusion sensor detection rod further comprises a display.

[0023] The display is arranged at the outer side end of the peripheral structure shell and is used for displaying the data detected by the gas sensor assembly.
