Description

Technical Field

[0001] This utility model relates to the field of detection instrument technology, and in particular to a portable volatile organic compound detector. Background Technology

[0002] A volatile organic compound (VOC) detector is a device used in environmental monitoring to detect volatile organic compounds (VOCs). It is equipped with VOCs sensors, concentration sensors, temperature sensors, and flow rate sensors. During operation, gas is drawn into the detector, and the sensors detect the composition, concentration, temperature, and flow rate of the VOCs. Existing VOC detectors typically have an inlet pipe protruding from the detector housing. This allows personnel to insert the inlet pipe into the hazardous area to extract air in cases involving industrial leaks, confined spaces (such as storage tanks and pipelines), or flammable and explosive environments, thus improving safety. However, the protruding inlet pipe presents several inconveniences, such as difficulty in carrying it and the risk of bending or breaking it during transport. Therefore, a portable VOC detector is proposed. Summary of the Invention

[0003] The purpose of this invention is to provide a portable volatile organic compound detector to solve the above-mentioned problems.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Reference Figures 1 to 6This utility model provides a portable volatile organic compound (VOC) detector, including a detector body 10 and a detection component 20. One end of the detector body 10 is provided with a mounting groove 11, the groove opening of which is provided with a threaded flange 13. A threaded cap 14 is provided on the threaded flange 13, which forms a sealed receiving space within the cavity of the mounting groove 11, capable of accommodating the detection component 20. The bottom of the mounting groove 11 is provided with an air inlet 12. During detection, the air to be tested can enter the detector body 10 through the air inlet 12 for detection by the internal VOCs sensor, concentration sensor, temperature sensor, and flow rate sensor. The detection component 20 includes a hollow telescopic rod 21, a detection head 22, and a retractable corrugated tube 23. One end of the telescopic rod 21 is slidably connected to the inner wall of the mounting groove 11, and the probe head 22 is disposed at the other end of the telescopic rod 21. The bellows 23 is sleeved inside the telescopic rod 21, with one end of the bellows 23 connected to the air inlet 12 and the other end connected to the probe head 22. A spring 24 is provided between the mounting groove 11 and the telescopic rod 21. When the threaded cover 14 is opened, the spring 24 ejects one end of the telescopic rod 21 out of the mounting groove 11.

[0028] Specifically, when carrying the detector, the telescopic rod 21 is compressed, the detection component 20 is placed in the mounting groove 11, and the threaded cover 14 is connected to the threaded flange 13, so that the detection component 20 is housed in the cavity of the mounting groove 11. In use, the threaded cover 14 is rotated and removed. After the threaded cover 14 separates from the threaded flange 13, the elastic force of the spring 24 pushes the detection head 22 and part of the telescopic rod 21 out of the mounting groove 11. At this time, the inspector applies a pulling force to the telescopic rod 21 to extend it, and the bellows 23 located inside the telescopic rod 21 extends accordingly. Subsequently, the detection head 22 can be inserted into the area to be detected, thereby improving the safety of the inspector. This utility model discloses a portable volatile organic compound detector where the detection component 20 can be housed in the mounting groove 11 when not in use (or when carried), and extended when in use, thus effectively improving the portability of the volatile organic compound detector.

[0029] Furthermore, the inner wall of the mounting groove 11 is provided with a sliding groove, and a protrusion 25 is provided on the outer side of the end of the telescopic rod 21 near the bottom of the mounting groove 11. The protrusion 25 can slide within the sliding groove. The sliding groove includes a first sliding groove 151, a second sliding groove 152, and a third sliding groove 153. The length direction of the first sliding groove 151 and the second sliding groove 152 is the same as the direction of the elastic force of the spring 24, and the first sliding groove 151 extends to the threaded flange 13. The ends of the first sliding groove 151 and the second sliding groove 152 near the bottom of the mounting groove 11 are connected by the third sliding groove 153. When installing the telescopic rod 21 into the mounting groove 11, the protrusion 25 is first slid into the mounting groove 11 along the first slide groove 151. When the slider reaches the bottom of the first slide groove 151, the telescopic rod 21 is rotated so that the protrusion 25 slides through the third slide groove 153 to the second slide groove 152. After the protrusion 25 slides into the second slide groove 152, under the elastic force of the spring 24, the protrusion 25 slides into the second slide groove 152, thus completing the installation of the telescopic rod 21. When the telescopic rod 21 needs to be replaced, the protrusion 25 can be pressed down into the third slide groove 153, and then the telescopic rod 21 can be rotated so that the protrusion 25 slides onto the first slide groove 151, thereby removing the telescopic rod 21. This technical solution avoids the detection component 20 sliding out of the mounting groove 11 when the detector is inverted; it also facilitates the replacement of telescopic rods 21 of different lengths.

[0030] Furthermore, the air inlet 12 is provided with an outer edge 16, and one end of the bellows 23 is sleeved on the outer edge 16. Correspondingly, the other end of the bellows 23 is sleeved on the air outlet of the probe head 22. This technical solution facilitates the replacement of the bellows 23.

[0031] Furthermore, an elastic sealing gasket is provided inside the threaded cap 14. When the threaded cap 14 is on, the waterproof performance of the detector is effectively improved. A rope connects the threaded cap 14 to the threaded flange 13. When the threaded cap 14 is removed, it is connected to the threaded flange 13 via the rope, preventing the threaded cap 14 from being easily lost during the use of the detector.

[0032] Furthermore, the detector body 10 is provided with a display screen 17 and buttons 18.

[0033] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
