Description

Technical Field

[0001] This utility model belongs to the field of gas detection technology, and in particular relates to a gas detector that is easy to dissipate heat. Background Technology

[0002] With increasing emphasis on atmospheric safety, air quality monitoring has become particularly important. As photoelectric monitoring and spectral analysis technologies have developed and matured, gas detection devices based on these principles have emerged in large numbers. Existing gas detection devices generally include a QCL laser, a mid-infrared laser detector, a retroreflector, and the gas being measured. These devices rely on a QCL laser to emit a broadband mid-infrared laser. The laser passes through the gas being measured, and different gases absorb the corresponding frequencies of mid-infrared laser light. The absorbed mid-infrared laser light is then introduced into the mid-infrared laser detector through multiple complex retroreflectors or other methods for signal processing and analysis. By comparing the absorption spectrum with samples in a database, the corresponding substances can be detected.

[0003] Existing technologies disclose several utility model patents in the field of gas detection technology. Among them, utility model patent CN216484586U discloses a gas detector with convenient heat dissipation. The gas detector includes a housing, a laser, and circuit control components. The heat dissipation structure includes: a substrate located in the middle of the housing, with a first mounting port on the substrate. The laser is mounted on one side of the first mounting port, and the circuit control components are mounted on both sides of the substrate. The housing has an air outlet opposite to the circuit control components. A cooling fan is mounted on the other side of the first mounting port opposite to the laser, and the housing has an air inlet opposite to the cooling fan. The circuit control components include a main control board, a power board, a data acquisition board, and a signal board. The housing also has air outlets corresponding to the main control board, power board, data acquisition board, and signal board. Compared with existing technologies, this application can effectively dissipate heat from the entire gas detector, improving its heat dissipation efficiency.

[0004] However, the above method still has the following drawbacks in actual use: the cleaning structure of the heat dissipation part of the gas detector is relatively simple, mainly cleaning the vents by cleaning brush. However, some dust will enter the machine through the vents after cleaning, which will cause damage to the internal components and reduce the service life of the gas detector.

[0005] Based on this, the present invention designs a gas detector that facilitates heat dissipation to solve the above problems. Utility Model Content

[0008] The cleaning structure overlaps below the filter mesh. The testing instrument has an auxiliary structure that overlaps on the filter mesh and is fixedly connected to the cleaning structure. The auxiliary structure includes a vibrating cylinder one, a vibrating cylinder two, a bevel gear set, and a drive motor. The top of the drive motor is connected to the bevel gear two, and one end of the vibrating cylinder two is connected to the bevel gear one.

[0019] 2. In this utility model, by setting an inclined block, a snap-fit ​​structure and a limiting groove, the protective plate is snapped into the limiting groove by the limiting plate. When the limiting plate slides in the limiting groove, the inclined block on the surface will contact the inclined plate. When the protective plate is completely attached to the testing instrument, the inclined plate will be reset by the action of the spring. The reset spring overlaps the upper part of the inclined block, thereby locking the position of the protective plate and preventing the position of the bevel gear two and the bevel gear set from shifting after the protective plate is fixed.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 ,

[0029] First embodiment:

[0030] This utility model provides a technical solution: a gas detector that facilitates heat dissipation, including a detection instrument 1, a detection head 2 fixedly connected to the top of the detection instrument 1, a display screen 3 set above the detection instrument 1, protective plates 4 on both sides of the detection instrument 1, a limiting groove 11 opened on the outside of the detection instrument 1, a limiting plate 5 fixedly connected to the outer surface of the protective plate 4, a wedge 6 fixedly connected to one side of the limiting plate 5, a snap-fit ​​structure 7 fixedly connected to the outside of the detection instrument 1, the snap-fit ​​structure 7 overlapping with the wedge 6, a sliding groove 13 opened on the outside of the detection instrument 1, a cleaning structure 8 fixedly connected to the outside of the detection instrument 1, the cleaning structure 8 slidingly connected in the sliding groove 13, and a filter mesh 12 set below the protective plate 4;

[0031] The cleaning structure 8 overlaps below the filter mesh 12. The testing instrument 1 is equipped with an auxiliary structure 14, which overlaps on the filter mesh 12 and is fixedly connected to the cleaning structure 8. The auxiliary structure 14 includes a first vibrating cylinder 1401, a second vibrating cylinder 1402, a bevel gear set 1404, and a drive motor 1405. The top of the drive motor 1405 is connected to the second bevel gear 1406, one end of the second vibrating cylinder 1402 is connected to the first bevel gear 1403, and the second vibrating cylinder 1402 is externally connected to a drive belt 1407.

[0032] Specifically, such as Figure 1-3 As shown, a data cable 10 is fixedly connected to the bottom of the testing instrument 1. Several heat dissipation holes 9 are opened on both sides of the testing instrument 1. The limiting plate 5 is snapped into the limiting groove 11. The snapping structure 7 includes a sleeve plate 701 and a spring 706. An inclined plate 702 is slidably connected inside the sleeve plate 701. A vertical plate 703 is fixedly connected above the inclined plate 702. A moving rod 704 is fixedly connected to one side of the vertical plate 703. The sleeve plate 701 is fixedly connected to the outside of the testing instrument 1. The moving rod 704 is slidably connected above the sleeve plate 701. One end of the moving rod 704 is connected to a fixed plate 705. The spring 706 is sleeved on the outer surface of the moving rod 704. The fixed plate 705 is connected to the top of the sleeve plate 701 through the spring 706. The inclined plate 702 overlaps with the inclined block 6.

[0033] By setting spring 706, when the limiting plate 5 slides in the limiting groove 11, the inclined block 6 on the surface will contact the inclined plate 702. When the inclined plate 702 is affected by the thrust, it will slide in the sleeve 701. When the inclined plate 702 moves, it will drive the spring 706 to deform through the fixed plate 705 and the moving rod 704, so that the spring 706 plays a certain supporting role for the movement of the inclined plate 702 and avoids the phenomenon of jamming when the inclined plate 702 moves.

[0034] Second embodiment:

[0035] Specifically, such as Figure 4 As shown, the cleaning structure 8 includes a fixed sleeve 801, which is fixedly connected to the side of the testing instrument 1. A push rod 802 is slidably connected inside the fixed sleeve 801. A cleaning plate 803 is fixedly connected to one end of the push rod 802. The cleaning plate 803 is slidably connected inside the slide groove 13 and overlaps the bottom of the filter mesh 12.

[0036] By setting the slide groove 13, the push rod 802 applies a pushing force to the cleaning plate 803, and the cleaning plate 803 will slide in the slide groove 13. This allows the slide groove 13 to guide the movement of the cleaning plate 803 and prevent the cleaning plate 803 from falling off during movement.

[0037] Third embodiment:

[0038] Specifically, such as Figure 5 As shown, vibrating cylinder 1401 is rotatably connected to one side of the protective plate 4, and vibrating cylinder 2 1402 is rotatably connected to the other side of the protective plate 4. Vibrating cylinder 2 1402 is connected to vibrating cylinder 1401 via a transmission belt 1407. The bevel gear set 1404 is rotatably connected inside the protective plate 4. The bevel gear set 1404 is formed by a rotating shaft and two bevel gear sets 1404. Bevel gear 2 1406 meshes with the bevel gear at one end of the bevel gear set 1404, and bevel gear 1 1403 meshes with the bevel gear at the other end of the bevel gear set 1404.

[0039] By setting a transmission belt 1407, the drive motor 1405 drives the second bevel gear 1406 to rotate, and the second bevel gear 1406 drives the first bevel gear 1403 to rotate through the bevel gear set 1404. Since the second vibrating cylinder 1402 is connected to the first vibrating cylinder 1401 through the transmission belt 1407, the first vibrating cylinder 1401 and the second vibrating cylinder 1402 can achieve synchronous rotation, which facilitates the vibration of dust from the filter mesh 12 to the outside.

[0040] Working principle and usage:

[0041] When the gas detector is in use, the protective plate 4 can be snapped into the limiting groove 11 by the limiting plate 5. When the limiting plate 5 slides in the limiting groove 11, the inclined block 6 on its surface will contact the inclined plate 702. When the inclined plate 702 is affected by the pushing force, it will slide in the sleeve plate 701. When the inclined plate 702 moves, it will drive the spring 706 to deform through the fixed plate 705 and the moving rod 704. When the protective plate 4 is completely attached to the detection instrument 1, the inclined plate 702 will be reset by the action of the spring 706. After the reset, the spring 706 overlaps the upper part of the inclined block 6.

[0042] The internal heat is then discharged through the filter mesh 12 below the protective plate 4. When the filter mesh 12 discharges hot gas for a long time, and the protective plate 4 is completely in contact with the side of the testing instrument 1, the bevel gear at one end of the bevel gear set 1404 will mesh with the second bevel gear 1406. When it is necessary to clean the dust in the filter mesh 12, the drive motor 1405 drives the second bevel gear 1406 to rotate, and the second bevel gear 1406 will drive the first bevel gear 1403 through the bevel gear set 1404 to rotate. The vibration cylinder 1402 is connected to the vibration cylinder 1401 via the transmission belt 1407, allowing both the vibration cylinder 1401 and the vibration cylinder 1402 to rotate within the protective plate 4. The vibration cylinder 1401 and the vibration cylinder 1402 vibrate the filter mesh 12, dislodging the dust from the filter mesh 12. The push rod 802 then applies a pushing force to the cleaning plate 803, which slides within the groove 13 and cleans the bottom of the filter mesh 12.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
