Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring, specifically a high-stability humidity sensor for a multi-parameter gas measuring instrument. Background Technology

[0002] The high-stability humidity sensor is the core component of a multi-parameter gas analyzer used for accurate and reliable measurement of environmental water vapor content. Its characteristics include minimal long-term accuracy drift and strong anti-interference ability. It can not only directly provide humidity data, but more importantly, it can perform real-time humidity compensation on the readings of other gas sensors to eliminate environmental humidity interference, thereby ensuring the accuracy and reliability of the final gas concentration value. It is the cornerstone of ensuring the measurement accuracy of the entire instrument.

[0003] In existing technologies, humidity sensors can accurately and reliably measure the water vapor content in the environment. However, when a humidity sensor is measuring, outside air usually needs to enter the sensor through one side of the measuring device before the sensor can take a measurement. However, when the measuring device is working, the internal circuitry, screen, and battery generate heat, which heats the outer casing and the internal air. This may cause data deviation and inaccurate readings from the humidity sensor. At the same time, when measuring in confined spaces such as cabinet gaps, ventilation holes, and pipe openings, the operator can only hold the device and put their arm into the confined space to take the measurement, which is very inconvenient. Furthermore, if the gap is smaller than the size of the device, it may be impossible to take a measurement. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, when the measuring device is in operation, the internal circuitry, screen, and battery generate heat, which heats the outer casing and the internal air. This may lead to data deviation and inaccurate readings of the humidity sensor. At the same time, when measuring in confined spaces such as cabinet gaps, ventilation holes, and pipe openings, the operator can only hold the device and put their arm into the confined space to make the measurement, which is very inconvenient. In addition, if the gap is smaller than the size of the device, it may be impossible to make a measurement. This utility model proposes a high-stability humidity sensor for a multi-parameter gas measuring device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a high-stability humidity sensor for a multi-parameter gas detector, including a detector body, a sensor body is provided in the inner cavity of the detector body, a mounting plate is fixedly connected to one side of the sensor body, and a moving mechanism is provided on the surface of the sensor body. The moving mechanism includes a fixed plate, the surface of which is fixedly connected to the inner cavity of the measuring instrument body. A moving plate is slidably connected to the inner cavity of the fixed plate, and the inner cavity of the moving plate is fixedly connected to the surface of the sensor body. A limit block is fixedly connected to one side of the moving plate. A limit groove is formed in the inner cavity of the fixed plate, and the surface of the limit block is slidably connected to the inner cavity of the limit groove. Cable routing holes and pull grooves are respectively formed on both sides of the moving plate. A snap-fit ​​frame is movably snapped onto one side of the mounting plate, and a dustproof net is fixedly connected to the inner cavity of the snap-fit ​​frame. A limit component is provided on one side of the dustproof net.

[0006] Preferably, the limiting component includes a mounting block disposed on one side of the measuring device body. The mounting block has a threaded rod threadedly connected to its inner cavity. The top of the movable plate has a threaded hole, and multiple threaded holes are provided, the size of which is adapted to the threaded rod.

[0007] Preferably, a mounting frame is fixedly connected to one side of the measuring device body, one side of the mounting frame is fixedly connected to one side of the mounting block, and a hinge door is rotatably connected to the inner cavity of the mounting frame.

[0008] Preferably, both the surface of the hinge door and one side of the fixing plate are provided with snap-fit ​​holes, and snap-fit ​​rods are movably snapped into the inner cavity of the snap-fit ​​holes.

[0009] Preferably, a rubber block is movably bonded to the inner cavity of the measuring device body, and one side of the rubber block is movably connected to one side of the sensor body.

[0010] Preferably, a sliding block is fixedly connected to one side of the limiting block, and an auxiliary groove is provided in the inner cavity of the limiting groove. The surface of the sliding block is slidably connected to the inner cavity of the auxiliary groove.

[0011] Preferably, a snap-fit ​​block is fixedly connected to one side of the snap-fit ​​frame, and a snap-fit ​​groove is provided on one side of the mounting plate, wherein the surface of the snap-fit ​​block is movably snapped into the inner cavity of the snap-fit ​​groove.

[0012] The advantages of this utility model are: This invention connects a movable plate to the sensor body, and then limits the movable plate by connecting a limiting block and a limiting groove. Simultaneously, the connection between the movable plate and the fixed plate allows the movable plate to move the sensor body along the fixed plate, enabling the sensor body to extend out of the measuring device body. The limiting component positions the movable plate. This movable mechanism allows the sensor body to extend out of the measuring device body, making it less susceptible to the influence of internal heat during measurement. It also allows the sensor body to be inserted into narrow gaps for measurement, increasing its adaptability. This solves the problem that when the measuring device is working, the internal circuitry, screen, and battery generate heat, which heats the outer casing and internal air, potentially causing data deviations and inaccurate readings. Furthermore, when measuring in confined spaces such as cabinet gaps, ventilation holes, and pipe openings, it is inconvenient for operators to hold the device and extend their arms into the narrow space. Additionally, if the gap is smaller than the device size, measurement may be impossible. Attached Figure Description

[0016] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail. This application discloses a high-stability humidity sensor for a multi-parameter gas detector. (Refer to...) Figure 1 and Figure 2 A high-stability humidity sensor for a multi-parameter gas detector includes a detector body 1, a sensor body 2 disposed in the inner cavity of the detector body 1, a mounting plate 3 fixedly connected to one side of the sensor body 2, and a moving mechanism 4 disposed on the surface of the sensor body 2. The moving mechanism 4 includes a fixed plate 401, the surface of which is fixedly connected to the inner cavity of the measuring instrument body 1. A moving plate 402 is slidably connected to the inner cavity of the fixed plate 401. The inner cavity of the moving plate 402 is fixedly connected to the surface of the sensor body 2. A limiting block 403 is fixedly connected to one side of the moving plate 402. A limiting groove 404 is opened in the inner cavity of the fixed plate 401. The surface of the limiting block 403 is slidably connected to the inner cavity of the limiting groove 404. Cable routing holes 405 and pulling grooves 409 are respectively opened on both sides of the moving plate 402. A snap-fit ​​frame 406 is movably snapped onto one side of the mounting plate 3. A dustproof net 407 is fixedly connected to the inner cavity of the snap-fit ​​frame 406. A limiting component 408 is provided on one side of the dustproof net 407.

[0018] The measuring device body 1 can comprehensively assess the environmental safety status, and issue an alarm when the concentration of hazardous gases exceeds the standard or oxygen is insufficient, so as to protect the life safety of personnel and provide key data support for industrial operations, emergency response and environmental monitoring. The sensor body 2 is the core component of the measuring device body 1 for accurate and reliable measurement of the environmental water vapor content. At the same time, the measuring device body 1 and the sensor body 2 are existing technologies in this field, so they will not be described in detail here. Furthermore, the mounting plate 3 provides some protection for the sensor body 2, preventing damage from friction or impact. Simultaneously, the measuring device body 1 connects to the moving plate 402 via the connection to the fixed plate 401. The moving plate 402 is connected to the limiting block 403, and a limiting groove 404 is provided on one side of the fixed plate 401, allowing the limiting block 403 to slide within it. The limiting action provided by the limiting block 403 and the limiting groove 404 enables the moving plate 402 to smoothly slide the sensor body 2 along the surface of the fixed plate 401, allowing the sensor body 2 to move outside the measuring device body 1. This ensures that the measurement of the sensor body 2 is unaffected by the internal heat of the measuring device body 1, resulting in more accurate measurements. By opening a wiring hole 405 on one side of the movable plate 402, it is convenient for the staff to connect the wiring on the surface of the sensor body 2 to the measuring instrument body 1. When connecting the sensor body 2, the staff leaves an extra section of wiring so that the sensor body 2 can move smoothly. At the same time, the mounting plate 3 provides a connection to the dustproof net 407 through the connection with the snap-fit ​​frame 406. The dustproof net 407 can provide protection for the sensor body 2, so that external dust and foreign objects cannot directly enter the interior of the sensor body 2 through the air inlet slot on one side of the sensor body 2. At the same time, a pull groove 409 is opened on one side of the fixed plate 401, which makes it convenient for the staff to pull the sensor body 2 out from the interior of the fixed plate 401. After the sensor body 2 is pulled out, the staff can limit the sensor body 2 through the limiting component 408.

[0019] Reference Figure 5 and Figure 6The limiting component 408 includes a mounting block 4081, which is disposed on one side of the measuring body 1. A threaded rod 4082 is threadedly connected to the inner cavity of the mounting block 4081. A threaded hole 4083 is provided on the top of the moving plate 402. Multiple threaded holes 4083 are provided, and the size of the multiple threaded holes 4083 is adapted to the threaded rod 4082. The mounting block 4081 can provide installation and connection for the threaded rod 4082. At the same time, by providing multiple threaded holes 4083 on the bottom of the moving plate 402, the threaded rod 4082 can be connected to the threaded hole 4083. By placing the mounting block 4081 on one side of the measuring body 1, when the sensor body 2 is pulled out a certain distance, the operator can rotate the threaded rod 4082 into the appropriate threaded hole 4083. Thus, the threaded connection between the threaded rod 4082 and the threaded hole 4083 limits the sensor body 2, making it difficult for the sensor body 2 to detach from the contact with the fixed plate 401 or to reset.

[0020] Reference Figure 2 and Figure 5 A mounting frame 5 is fixedly connected to one side of the measuring instrument body 1. One side of the mounting frame 5 is fixedly connected to one side of the mounting block 4081. A hinge door 6 is rotatably connected to the inner cavity of the mounting frame 5. The mounting frame 5 is connected to the measuring instrument body 1 and the mounting block 4081. At the same time, the mounting frame 5 can provide installation and connection for the hinge door 6. When the measuring instrument body 1 stops working, the operator can close the hinge door 6, so that the hinge door 6 can protect the sensor body 2 and prevent foreign objects and dust from entering the interior of the measuring instrument body 1.

[0021] Reference Figure 3 and Figure 5 Both the surface of the hinge door 6 and one side of the fixing plate 401 are provided with snap-fit ​​holes 7. The inner cavity of the snap-fit ​​hole 7 is movably snapped with a snap-fit ​​rod 8. The snap-fit ​​hole 7 can provide installation and connection for the snap-fit ​​rod 8. When the hinge door 6 is closed, the operator can insert the snap-fit ​​rod 8 into the inside of the snap-fit ​​hole 7, and limit the hinge door 6 by the mutual snap-fit ​​between the snap-fit ​​rod 8 and the snap-fit ​​hole 7, so that the hinge door 6 is not easily displaced by external vibrations, thus losing its protective function for the sensor body 2.

[0022] Reference Figure 2 and Figure 3 A rubber block 9 is movably bonded to the inner cavity of the measuring body 1. One side of the rubber block 9 is movably connected to one side of the sensor body 2. The measuring body 1 can provide installation and connection for the rubber block 9. At the same time, the rubber block 9 is connected to the sensor body 2. The setting of the rubber block 9 can prevent the sensor body 2 from being worn due to frequent friction with the inside of the measuring body 1 when it moves.

[0023] Reference Figure 3 and Figure 4 A sliding block 10 is fixedly connected to one side of the limiting block 403. An auxiliary groove 11 is provided in the inner cavity of the limiting groove 404. The surface of the sliding block 10 is slidably connected to the inner cavity of the auxiliary groove 11. The limiting block 403 can provide installation and connection for the sliding block 10. At the same time, the limiting groove 404 and the auxiliary groove 11 are interconnected, and the sliding block 10 and the auxiliary groove 11 are interconnected. By setting the sliding block 10 and the auxiliary groove 11, the limiting ability of the moving plate 402 can be further increased, so that when the moving plate 402 drives the sensor body 2 to move, it can move more smoothly and is less prone to deviation and shaking.

[0024] Reference Figure 2 and Figure 3 A snap-fit ​​block 12 is fixedly connected to one side of the snap-fit ​​frame 406, and a snap-fit ​​groove 13 is provided on one side of the mounting plate 3. The surface of the snap-fit ​​block 12 is movably snapped into the inner cavity of the snap-fit ​​groove 13. The snap-fit ​​frame 406 can provide installation and connection for the snap-fit ​​block 12. By providing a snap-fit ​​groove 13 on one side of the mounting plate 3, the snap-fit ​​block 12 and the snap-fit ​​groove 13 can be snapped into each other, so that when the staff needs to replace the dustproof net 407, it can be more convenient and smooth.

[0025] Working Principle: Before use, when the operator needs to use the sensor body 2 for measurement, the locking rod 8 can be pulled out and the hinge door 6 opened. The sensor body 2 can then be used to measure the external environment. When the measured data is inaccurate or when measurement is required in a confined space, the sensor body 2 can be pulled out through the pull groove 409. When the pull groove 409 is under force, it will drive the moving plate 402 and the limiting block 403 to move. Simultaneously, due to the limiting effect provided by the limiting block 403 and the limiting groove 404, the moving plate 402 can smoothly slide along the surface of the fixed plate 401, thereby moving the sensor body 2. After the operator pulls the sensor body 2 out a certain distance, it can be manually rotated. The threaded rod 4082 is rotated to a suitable threaded hole 4083, thereby limiting the movement plate 402 and the sensor body 2 through the threaded connection between the threaded rod 4082 and the threaded hole 4083. At this time, the measuring instrument body 1 can be held and the sensor body 2 can be inserted into a narrow gap or a suitable place for measurement. The moving mechanism 4 enables the sensor body 2 to measure gaps and pipes that are smaller than the measuring instrument body 1 but larger than the sensor body 2, thereby increasing the adaptability of the sensor body 2. Furthermore, due to the extension of the sensor body 2, the sensor body 2 is less affected by the heat inside the measuring instrument body 1, and the measured data can be more accurate and correct.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
