Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gas measurement, in particular to a BVOC measuring tube. Background Art
[0002] BVOC, or biovolatile organic compounds, are volatile organic compounds naturally released by plants and other organisms. They include terpenes, alcohols, esters and other compounds. These BVOCs act as a "language" among plants, helping them communicate and establish insect resistance pathways. At the same time, they also have an impact on the atmospheric environment and can generate photochemical pollutants such as ozone.
[0003] Existing BVOC measuring tubes can generally be reused 100 times, but in actual use, it is difficult to record the number of times the BVOC measuring tubes have been used, resulting in premature discarding of the BVOC measuring tubes, increased costs, and waste of resources, or excessive use of the BVOC measuring tubes, which affects the accuracy of the measurement results. In addition, the BVOC measuring tubes can only be kept sealed for 7 days after sampling, and the operator is required to mark the sampling time on the surface of the plastic bag with a marker. When sampling multiple batches at the same time, the operator needs to write records multiple times, which affects the measurement efficiency and manual records are prone to errors. At the same time, the outer surface of the BVOC measuring tube generally uses a single arrow to indicate the measurement direction, but in actual use, sampling and measurement need to be plugged in from different directions, and the single arrow can easily cause confusion among users. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a connection between the internal parts of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0029] The following describes an embodiment of the present invention based on its overall structure.
[0030] Example 1:
[0031] A BVOC measuring tube, such as Figure 1-Figure 4 As shown, it includes a measuring tube body 1, a timing mechanism 5 and a counting mechanism 6. The timing mechanism 5 includes a mounting groove 501. The inner wall of the mounting groove 501 is provided with a magnetic block 502. The magnetic block 502 is magnetically connected to a fixed block 503. The outer surface of the fixed block 503 is fixedly connected to a timer 504.
[0032] The counting mechanism 6 includes a pointing block 601, a damping shaft 602 is provided on one side of the pointing block 601, the outer surface of the damping shaft 602 is rotatably connected to a scale ring 603, and the outer surface of the scale ring 603 is provided with a digital mark 604. The magnetic block 502 is connected by magnetic attraction, and the timer 504 can be easily installed on the measuring tube body 1 and disassembled when needed. The damping shaft 602 provides stable rotational resistance, so that the scale ring 603 can remain stable during rotation and will not rotate accidentally due to slight touch.
[0033] See Figure 2 There are several digital identifications 604, which are evenly spaced in a circular array. The digital identifications 604 are evenly spaced on the scale ring 603, forming a complete circular scale, providing operators with a clear and intuitive measurement reference. The digital identifications 604 allow the number of times the measuring tube is used to be accurately recorded and tracked, which helps to improve the accuracy and consistency of measurement.
[0034] See Figure 1Sealing caps 2 are installed at both ends of the measuring tube body 1. These caps are mirrored along the central axis of the measuring tube body 1. Their primary function is to prevent BVOC sample leakage and external contamination. By tightly fitting the ports of the measuring tube body 1, the caps 2 provide a reliable seal, ensuring the integrity and accuracy of the sample during sampling, transportation, and testing. They also protect the BVOC sample from external environmental influences such as oxygen, moisture, and dust. These external factors could damage the sample or interfere with the measurement results, but the presence of the caps 2 effectively isolates these interference sources.
[0035] Example 2:
[0036] See Figure 1 、 Figure 4 A first color band 3 is provided on the outer surface of the measuring tube body 1, and a second color band 4 is provided on one side of the first color band 3. Through the obvious marking, the operator can quickly identify the measuring tube that needs to be sampled, reducing the possibility of misoperation and improving the accuracy of the sampling process. The color band can enhance the operator's alertness during the detection process, ensuring that each step is strictly implemented, thereby improving the reliability of the measurement and preventing confusion that may occur during use.
[0037] See Figure 1 、 Figure 4 The first color band 3 is green and the second color band 4 is red. The first color band 3 and the second color band 4 are of different colors, which provides intuitive visual guidance for the operator, making the sampling and detection process clearer and effectively preventing operational confusion. Through the rapid identification of the color bands, the operator can quickly distinguish the different usage states or directions of the measuring tube, thereby improving the operational efficiency of sampling and detection.
[0038] See Figure 1 、 Figure 4 The first color band 3 and the second color band 4 are symmetrically arranged along the central axis of the measuring tube body 1, and a measuring tube batch number identification is set between the first color band 3 and the second color band 4. The measuring tube batch number identification is located between the first color band 3 and the second color band 4, which is convenient for operators to quickly find and record. This enables the use history and batch information of each measuring tube to be effectively tracked, which is helpful for quality management and problem troubleshooting. Through the batch number identification, the quality monitoring and evaluation of the measuring tubes in the same batch can be realized, ensuring the reliability and consistency of the measurement results.
[0039] The implementation principle of the present utility model is as follows: first, the green ribbon is used in the direction of docking when sampling, and the red ribbon is used in the direction of docking when testing to prevent users from being confused. After sampling, the operator can magnetically adsorb the fixed block 503 in the installation slot 501 and start the timer 504 to time the unified batch. After the test is completed, the fixed block 503 can be removed and reused, and at the same time, the scale ring 603 is rotated to align the next digital mark 604 with the pointing block 601 to record the number of times the measuring tube body 1 is used.
[0040] Parts not involved in the present invention are the same as those in the prior art or can be implemented by using the prior art, and will not be described in detail here.
[0041] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention.
