[0029] Embodiment 2: The technical content disclosed in this embodiment is an improvement made on the basis of the above-mentioned embodiment 1. The existing inconvenience in adjusting the angle of the probe limits the scope of use of the device and increases the difficulty and complexity of installation.

[0030] In this technical solution, Figure 1As shown, by using the setting of the fastening bolt 12 and the nut 13, after the angle adjustment of the support frame 5 is completed, the nut 13 is rotated to move along the fastening bolt 12 to tighten the adjusted support frame 5, thereby preventing the support frame 5 from deflecting and shaking, and improving the stability of the connection.
[0031] Its use is as Figure 1 and Figure 3 According to the technical solution shown, when the angle of the probe needs to be adjusted, the support frame 5 is rotated so that the support frame 5 drives the probe rod 6 and the heating element 7 to rotate synchronously. At the same time, the support frame 5 will also drive the connecting shaft 8 to rotate synchronously, so that the rotation angle can be checked through the scale indicated by the pointer 9 on the connecting shaft 8. Further, the support frame 5 will drive the moving block 11 to slide up and down, so that the fastening bolt 12 slides along the inner wall of the slide groove 10.

[0032] Embodiment 3: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned embodiments 1 and 2. Two heating devices will increase the energy consumption of the device, and the heating range is small, resulting in uneven heating. In order to further solve this technical problem, this technical solution is as follows: Figure 2 and Figure 4 As shown, a heating assembly of the probe is disclosed, wherein a total pressure through hole 14 is provided in a probe rod 6, and a static pressure through hole 15 is provided below the total pressure through hole 14, and one end of the total pressure through hole 14 and the static pressure through hole 15 are connected to a nozzle 16, a heat conducting sheet 18 is fixedly connected to the side of the heating element 7, and a guide fin 17 is fixedly connected to the heating element 7, the total pressure through hole 14 and the static pressure through hole 15 are arranged in a fan shape along the center point of the probe rod 6, and the side wall of the total pressure through hole 14 is directly connected to the static pressure through hole 15, and the heat conduction The sheet 18 is set with the same material structure, and there are two heat conductive sheets 18.

At the same time, the guide fins 17 can block some larger particles and impurities, play a certain protective role, and reduce the risk of blockage.
[0034] Its use is as Figure 2 and Figure 4 The technical solution shown, first, when in use, the airflow first passes through the guide fin 17 arranged at the front side of the total pressure through hole 14, and flows into the total pressure through hole 14 at a uniform speed through the guide fin 17, and the airflow entering the total pressure through hole 14 will be divided, a part of the airflow continues to flow along the total pressure channel for measuring the total pressure, and the other part of the airflow enters the static pressure through hole 15 parallel to the total pressure through hole 14. At this time, the airflow will be affected by the specific structure and sensor in the channel, thereby generating a measurable pressure change, and then the nozzle 16 will balance the pressure difference inside and outside the probe, reducing the influence of the pressure change on the measurement result;
[0035] When the temperature outside the support frame 5 and the probe rod 6 drops, the heater 7 is turned on. At this time, the heater 7 transfers the heat to the heat conductive sheet 18, and further transfers the heat to the support frame 5 and the probe rod 6 through the heat conductive sheet 18 to heat them and prevent them from freezing.
