Description

Technical Field

[0001] The utility model belongs to the technical field of humidity sensors, in particular to a high-temperature and high-humidity environment auxiliary calibration device for humidity sensors. Background Art

[0002] A humidity sensor is a device used to measure the water vapor content in an environment. Humidity sensors are primarily classified into two categories based on their operating principle and structure: capacitive and resistive. Humidity sensors operate in high-temperature and high-humidity environments. To ensure the accuracy of measured data, they are often equipped with calibration equipment for auxiliary monitoring. A commonly used auxiliary calibration device is a humidity standard. A humidity standard uses a dry-bulb method, a salt solution method, a humidity generator method, or a dew point method to provide a stable humidity reference, thereby calibrating the humidity sensor. The humidity standard should be installed near the humidity sensor's measurement area to ensure the sensor is exposed to the humidity provided by the calibration equipment.

[0003] Humidity standards need to be installed close to humidity sensors to be most effective. Traditional humidity standards are often located a certain distance from humidity sensors, making them difficult to align with. Furthermore, different types of humidity sensors are difficult to quickly adapt to humidity standards, making it difficult to quickly calibrate and correct humidity sensors.

[0004] To this end, the utility model provides a humidity sensor high temperature and high humidity environment auxiliary calibration device. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the utility model to solve its technical problems is: the utility model describes a high-temperature and high-humidity environment auxiliary calibration device for a humidity sensor, comprising a humidity sensor body and a humidity standard, wherein an air extraction hole is provided on the side of the humidity standard; two symmetrically arranged fixing frames are fixedly installed on one side of the humidity sensor body, a sliding block is slidably connected to the fixing frame via a first spring, a splint is fixedly installed on the end of the sliding block away from the first spring, and a side of the splint away from the sliding block is made of a non-slip material.

[0007] Furthermore, an inclined guide plate is fixedly installed on the top of the clamping plate, and a plurality of guide columns are rotatably connected to the sides of the two guide plates that are close to each other.

[0008] Furthermore, a hollow connecting frame is fixedly installed on one side of the fixed frame away from the humidity sensor body, and a baffle is sealed and slidably connected to the inside of the connecting frame through an elastic rope; the sliding block and the fixed frame are sealed and slidably connected, and a connecting pipe is installed between the fixed frame and the connecting frame.

[0009] Furthermore, a base is fixedly mounted on one side of the humidity sensor body close to the fixing frame, and a groove is formed on the top of the base.

[0010] Furthermore, two symmetrically arranged hollow fixed columns are fixedly installed inside the base, and the internal sealing sliding connection of the fixed columns is a sealing disk, the bottom of the sealing disk is fixedly installed with a sliding rod, the bottom of the sealing disk is fixedly installed with a second spring, the end of the second spring away from the sealing disk is fixedly connected to the base, and a hose is fixedly installed on the top of the fixed column, and the end of the hose away from the fixed column is connected to the exhaust hole.

[0011] Furthermore, a connecting plate is fixedly mounted on one end of the sliding rod away from the sealing disk, and a plurality of rubber pads are fixedly mounted on the top of the connecting plate.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. The present invention discloses a humidity sensor calibration device for high-temperature and high-humidity environments. The bottom of the humidity standard first contacts the guide plate and guide post at the top of the clamping plate. The inclined guide plate and guide post then propel the two clamping plates apart, thereby increasing the gap between the two clamping plates and facilitating the entry of the humidity standard between them. As the sliding block slides, it squeezes the gas within the fixed block, allowing the compressed gas to enter the connecting frame through the connecting tube. This pushes the baffle within the connecting frame to slide, causing the baffle to slide directly in front of the humidity standard. This allows the two clamping plates to not only clamp the humidity standard but also shield it, effectively preventing the front end of the humidity standard from being left without a fixed component, thereby more efficiently securing the humidity standard. The designed clamping plate and baffle cooperate to quickly secure the humidity standard to one side of the humidity sensor body, ensuring close contact between the humidity standard and enabling efficient gap calibration. Furthermore, the designed clamping plate is adaptable to different models of humidity standards, enabling fast and efficient installation and removal.

[0014] 2. The utility model describes a humidity sensor high temperature and high humidity environment auxiliary calibration device, which connects one end of a hose to the exhaust hole of a humidity standard and presses the humidity standard, causing the humidity standard to slide downward with the connecting plate, slide rod, sealing plate and second spring. Since the sealing plate extracts the gas and water inside the humidity standard through the hose, it can quickly extract the accumulated water inside the humidity standard, effectively preventing the accumulation of water from affecting its normal operation. At this time, the water is in the fixed column, and the sealing plate continues to slide to separate it from the fixed column, thereby draining the water in the fixed column. When the slide rod is released, the slide rod and sealing plate will reset to the fixed column under the action of the second spring, making it convenient for next use.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figures 1 to 5As shown, the humidity sensor high-temperature and high-humidity environment auxiliary calibration device described in the embodiment of the present invention includes a humidity sensor body 1 and a humidity standard 2. The humidity standard 2 has an exhaust hole 3 on its side. Two symmetrically arranged fixed frames 4 are fixedly installed on one side of the humidity sensor body 1. A sliding block 5 is slidably connected to the fixed frame 4 via a first spring 6. A clamping plate 7 is fixedly installed on the end of the sliding block 5 away from the first spring 6. The side of the clamping plate 7 away from the sliding block 5 is made of a non-slip material. An inclined guide plate 8 is fixedly installed on the top of the clamping plate 7. The sides of the two guide plates 8 that are close to each other are rotatably connected to a number of guide columns 9.

[0024] Specifically, a hollow connecting frame 10 is fixedly mounted on the side of the fixed frame 4 facing away from the humidity sensor body 1. A baffle 11 is sealed and slidably connected to the interior of the connecting frame 10 via elastic cords. The sliding block 5 is sealed and slidably connected to the fixed frame 4, with a connecting tube 12 installed between the fixed frame 4 and the connecting frame 10. A base 13 is fixedly mounted on the side of the humidity sensor body 1 facing the fixed frame 4. The top of the base 13 has a groove.

[0025] During operation, when the humidity sensor body 1 is in use, the humidity standard 2 is first placed on one side of the humidity sensor body 1. The humidity standard 2 is moved toward the two clamps 7, so that the bottom of the humidity standard 2 first contacts the guide plate 8 and guide post 9 at the top of the clamps 7. The inclined guide plates 8 and guide posts 9 are then used to spread the two clamps 7 apart, causing them to slide away from each other, thereby increasing the gap between the two clamps 7 and facilitating the entry of the humidity standard 2 between the two clamps 7. The clamps 7 are retracted and slid within the fixed frame 4 by means of the sliding block 5. As the sliding block 5 slides, it squeezes the gas within the fixed block, causing the compressed gas to enter the connecting frame 10 through the connecting tube 12 and push the baffle 11 within the connecting frame 10 to slide, causing the baffle 11 to slide directly in front of the humidity standard 2. Thus, while the two clamps 7 clamp the humidity standard 2, the baffle 11 can also block the humidity standard 2, effectively preventing the front end of the humidity standard 2 from being without a fixed component, thereby more efficiently securing the humidity standard 2. At the same time, the base 13 at the bottom of the humidity sensor body 1 can effectively prevent the humidity standard 2 from falling when being installed.

[0026] The combination of the clamping plate 7 and the baffle 11 allows the humidity standard 2 to be quickly secured to one side of the humidity sensor body 1, ensuring close contact with the humidity sensor body 1 and enabling efficient gap calibration. Furthermore, the clamping plate 7 is adaptable to different models of humidity standards 2, enabling fast and efficient installation and removal.

[0027] Two symmetrically arranged hollow fixed columns 14 are fixedly mounted inside the base 13. A sealing disc 16 is slidably connected to the interior of the fixed columns 14. A sliding rod 15 is fixedly mounted to the bottom of the sealing disc 16. A second spring 17 is fixedly mounted to the bottom of the sealing disc 16. The end of the second spring 17 away from the sealing disc 16 is fixedly connected to the base 13. A hose 18 is fixedly mounted on the top of the fixed columns 14. The end of the hose 18 away from the fixed columns 14 is connected to the air extraction hole 3. A connecting plate 19 is fixedly mounted on the end of the sliding rod 15 away from the sealing disc 16. Several rubber pads are fixedly mounted on the top of the connecting plate 19.

[0028] During operation, after the humidity standard 2 is installed, one end of the hose 18 is connected to the air extraction hole 3 of the humidity standard 2. At this time, the bottom of the humidity standard 2 is on the connecting plate. After the humidity standard 2 is used for a long time in a high temperature and high humidity environment, moisture or condensation will accumulate inside the humidity standard 2. At this time, the humidity standard 2 is pressed so that the humidity standard 2 slides downward with the connecting plate, the slide bar 15, the sealing plate 16 and the second spring 17. Since the sealing plate 16 extracts the gas and water inside the humidity standard 2 through the hose 18 (the housing of the humidity standard 2 is provided with an air inlet), it is possible to quickly extract the water inside the humidity standard 2, effectively preventing moisture accumulation from affecting its normal operation. At this time, the moisture is in the fixed column 14, and the sealing plate 16 continues to slide so that it is separated from the fixed column 14, and the water in the fixed column 14 is discharged. When the slide bar 15 is released, the slide bar 15 and the sealing plate 16 will be reset to the fixed column 14 under the action of the second spring 17, so as to facilitate the next use.

[0029] Working Principle: When using the humidity sensor body 1, first place the humidity standard 2 on one side of the humidity sensor body 1. The humidity standard 2 is moved toward the two clamping plates 7, causing the bottom of the humidity standard 2 to first contact the guide plates 8 and guide posts 9 at the top of the clamping plates 7. The inclined guide plates 8 and guide posts 9 then spread the two clamping plates 7 apart, causing them to slide away from each other, thereby increasing the gap between them and facilitating the entry of the humidity standard 2 between them. The clamping plates 7 are retracted and slid within the fixed frame 4 by means of sliding blocks 5. As they slide, the sliding blocks 5 squeeze the air within the fixed blocks, allowing the compressed air to enter the connecting frame 10 through the connecting tube 12. This pushes the baffle 11 within the connecting frame 10 to slide, causing it to slide directly in front of the humidity standard 2. This allows the humidity standard 2 to be clamped by the two clamping plates 7 while also being blocked by the baffle 11, effectively preventing the front of the humidity standard 2 from being without a fixed component, thereby more efficiently securing the humidity standard 2. At the same time, the base 13 at the bottom of the humidity sensor body 1 can effectively prevent the humidity standard 2 from falling when being installed.

[0030] After the humidity standard 2 is installed, one end of the hose 18 is connected to the air extraction hole 3 of the humidity standard 2. At this time, the bottom of the humidity standard 2 is on the connecting plate. After the humidity standard 2 is used for a long time in a high temperature and high humidity environment, moisture or condensation will accumulate inside the humidity standard 2. At this time, the humidity standard 2 is pressed so that the humidity standard 2 slides downward with the connecting plate, the slide bar 15, the sealing plate 16 and the second spring 17. Since the sealing plate 16 extracts the gas and water inside the humidity standard 2 through the hose 18 (the housing of the humidity standard 2 is provided with an air inlet), it is possible to quickly extract the water inside the humidity standard 2, effectively preventing moisture accumulation from affecting its normal operation. At this time, the moisture is in the fixed column 14, and the sealing plate 16 continues to slide so that it is separated from the fixed column 14, and then the water in the fixed column 14 is discharged. When the slide bar 15 is released, the slide bar 15 and the sealing plate 16 will be reset to the fixed column 14 under the action of the second spring 17, so as to facilitate the next use.
