Description

Technical Field

[0001] This invention relates to the field of portable temperature measuring instruments, specifically a portable temperature measuring instrument for chemical applications. Background Technology

[0002] The portable temperature measuring instrument integrates signal conditioning circuitry and a microcontroller, and is equipped with a digital display screen. It contains key components such as thermocouples and resistance temperature detectors, enabling it to convert the electrical signals generated by the sensors into temperature values ​​for intuitive reading. During measurement, the instrument's temperature probe needs to be in close contact with the object being measured or placed in the target medium. Accuracy is ensured through key technologies such as cold junction compensation, and the measurement results are then accurately read from the screen.

[0003] Patent publication number CN113391183B relates to the field of portable temperature measuring instrument technology. It includes a housing and a mounting frame fixed within the housing. The mounting frame has symmetrically arranged detection slots, each containing a first electrode. Two sets of ammeters are mounted on the mounting frame and electrically connected to the first electrode. A bidirectional lead screw is rotatably connected within the housing. Slider blocks are symmetrically threaded at both ends of the bidirectional lead screw. Each slider has a clamping groove containing a second electrode, which is positioned to match the first electrode. A battery is mounted on the slider. This invention, through the arrangement of a liquid extraction mechanism, a heating chamber, and a heat pipe, ensures that the two sets of detection slots have the same temperature. The ammeters facilitate direct observation of the temperature characteristics differences between semiconductor device samples and standards.

[0004] The aforementioned patent facilitates intuitive observation of the temperature characteristics differences between semiconductor device samples and standards through the use of an ammeter. However, its probes are typically fixed and exposed or require manual insertion and removal. Fixed, exposed probes are easily damaged or deformed during transport and storage due to impacts, leading to inaccurate measurements. Furthermore, corrosive gases or dust in chemical environments can easily contaminate the sensitive parts of the probe, affecting measurement accuracy. More importantly, the probe length is not adjustable. When facing containers of varying depths, the instrument often cannot effectively reach the interior of the liquid, resulting in measurement failures or obtaining inaccurate temperatures only at the liquid surface, thus affecting precise control of the process. This not only limits the instrument's applicable scenarios but also reduces the efficiency and reliability of the testing work. The manual connection of the probe is cumbersome, increasing preparation time and posing a risk of misoperation leading to poor circuit contact. These shortcomings collectively restrict the practicality and reliability of traditional portable temperature measuring instruments in complex chemical environments. Summary of the Invention

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. In this invention, the probe is extended by pressing the button when holding the instrument. The natural gripping action can simultaneously trigger the circuit connection and probe extension, minimizing preparation time and making temperature measurement simple and fast. When not in use, the probe is protected inside the instrument housing, reducing the possibility of impact, contamination, or corrosion, and extending its service life. The movement of the limit block will contact the inner wall of the adjustment groove, and the extension length of the probe can be adjusted by the contact between the limit block and the inner wall of the adjustment groove. When it is necessary to test containers or liquids of different depths, the tester does not need to replace the entire probe. He can simply manually pull the probe out to the required length, and the mechanism will automatically lock. This flexible adjustment capability greatly expands the application range of the instrument, enabling it to easily cope with the testing needs of various depths, from shallow dishes to deep barrels.

[0024] 2. In this invention, the surface of the probe comes into contact with the surface of the outer scraper, which cleans the probe surface to prevent impurities from adhering to the probe's outer wall during testing, thus affecting the accuracy of the test. Before each measurement, the probe's surface automatically contacts and scrapes against the outer scraper. This action effectively removes any residual droplets, condensates, dust, or solid contaminants that may have adhered to the probe after the previous use, ensuring that the probe enters the test medium in a clean state. This avoids the decrease in thermal conductivity and temperature response lag caused by probe contamination, thus guaranteeing the accuracy and reliability of each measurement data from the source.

[0025] 3. In this invention, when the pressure plate moves downward, it firmly presses down on the ring frame. This rigid clamping effectively prevents vibration or displacement of the ring frame during the cleaning process, ensuring the stability and consistency of the contact between the outer scraper and the probe surface. This guarantees the effectiveness and reliability of each cleaning action, avoiding incomplete cleaning or probe wear caused by component shaking. The closing baffle reset process pushes the key to release the limit on the ring frame, and the push block pushes the ring frame, allowing the entire ring frame assembly to be easily removed. This disassembly design greatly simplifies the maintenance process, reduces the user's maintenance difficulty and time cost, and ensures that the equipment can continuously work in optimal condition.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-8 One embodiment of the present invention is: a portable temperature measuring instrument for chemical use, comprising an instrument 1, and the portable temperature measuring instrument further comprising:

[0038] Connector 2 is located at the bottom of the inner wall of instrument 1. A fixing post 3 is fixedly installed on the inner wall of instrument 1. An interface 4 is slidably installed on the inner wall of the fixing post 3. The interface 4 is matched with connector 2.

[0039] The sliding sleeve 5 is slidably installed on the inner wall of the fixed column 3.

[0040] The probe 6 is set on the inner wall of the sliding sleeve 5. A sliding groove is opened on the top of the instrument 1, and the probe 6 contacts the inner wall of the sliding groove.

[0041] A pushing device for moving the probe 6 toward the outside of the instrument 1 during use is provided on the outer wall of the instrument 1;

[0042] A cleaning device for cleaning the outer wall of probe 6 during use is installed on the outer wall of instrument 1;

[0043] An auxiliary device for quickly disassembling contaminated cleaning equipment is installed on the outer wall of instrument 1.

[0044] The pushing device includes a button plate 7, a first connecting rod 8, and a second connecting rod 9. The button plate 7 slides through the outer wall of the instrument 1. One end of the first connecting rod 8 is rotatably connected to the interface 4, and the other end of the first connecting rod 8 is rotatably connected to the button plate 7. One end of the second connecting rod 9 is rotatably connected to the button plate 7, and the other end of the second connecting rod 9 is rotatably connected to the sliding sleeve 5.

[0045] The pushing device also includes an adjusting rod 10, a sliding plate 11, a button 12, and a limiting block 13. The adjusting rod 10 is slidably installed on the inner wall of the sliding sleeve 5. The probe 6 is fixedly connected to the adjusting rod 10. The sliding plate 11 is slidably installed on the inner wall of the adjusting rod 10. The button 12 slides through the inner wall of the adjusting rod 10. The limiting block 13 slides through the inner wall of the adjusting rod 10. An adjusting groove is provided on the side of the sliding sleeve 5 near the limiting block 13. The shape of the limiting block 13 matches the adjusting groove. When it is necessary to detect containers or liquids of different depths, the inspector does not need to replace the entire probe 6. He only needs to manually pull the probe 6 to the required length, and the mechanism will automatically lock.

[0046] The pushing device also includes an elastic element 1 between the sliding sleeve 5 and the fixed column 3. The elastic element 1 is provided to drive the sliding sleeve 5 to move inward toward the fixed column 3. The adjusting rod 10 is electrically connected to the sliding sleeve 5 via a cable. The sliding sleeve 5 is electrically connected to the interface 4 via a cable. The sliding plate 11 is provided to the adjusting rod 10 via an elastic element 2. The elastic element 2 is provided to drive the sliding plate 11 to move toward the adjusting groove.

[0047] In this embodiment, when the temperature of a liquid needs to be detected, simply insert probe 6 into the liquid. Probe 6 will then transmit the liquid's temperature data via cable to instrument 1 for processing, detection, and display. When needed, the operator must grip instrument 1 firmly. Gripping instrument 1 presses button 7, causing it to move inwards. The movement of button 7 pushes connecting rod 8, which in turn pushes interface 4 towards connector 2. Connector 2 is then inserted into interface 4, electrically connecting probe 6 to connector 2. During detection, probe 6... The generated data can be transmitted to instrument 1. When interface 4 moves, it pushes linkage 2 9 to move. Linkage 2 9 moves, which in turn pushes sliding sleeve 5 upward. Sliding sleeve 5 moves upward, which pushes probe 6 to extend away from instrument 1. At this time, probe 6 can be placed in the liquid for detection. The probe 6 is driven to extend by pressing the button 7 when holding instrument 1. The natural gripping action can simultaneously trigger the circuit to be turned on and probe 6 to extend, minimizing preparation time and making temperature measurement simple and fast. Furthermore, probe 6 is protected inside the instrument housing when not in use. This reduces the possibility of impacts, contamination, or corrosion, extending its service life. When the probe 6 is too short to reach the liquid, simply pull the probe 6, causing it to move the adjusting rod 10 away from the sliding sleeve 5. The movement of the adjusting rod 10 will then move the sliding plate 11, which in turn will move the button 12. As the button 12 moves, it loses contact with the inner wall of the sliding sleeve 5, releasing the limiting effect of the sliding sleeve 5 on the button 12. This, in turn, releases the limiting effect of the button 12 on the sliding plate 11, allowing the sliding plate 11 to push the button 12. Moving the sliding plate 11 away from the adjusting rod 10 will push the limiting block 13 to move. The limiting block 13 will then contact the inner wall of the adjusting groove, allowing the length of the probe 6 to be adjusted. When it is necessary to test containers or liquids of different depths, the tester does not need to replace the entire probe 6. He can simply pull the probe 6 out to the required length manually, and the mechanism will automatically lock. This flexible adjustment capability greatly expands the application range of the instrument, enabling it to easily meet the testing needs of various depths, from shallow dishes to deep barrels.

[0048] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the portable temperature measuring instrument for chemical use further includes a cleaning device and an auxiliary device.

[0049] The cleaning device includes a connecting rod 21, a sliding block 22, a connecting rod 23, a sliding rod 24, a baffle 25, and a collar 26. The sliding block 22 is slidably installed on the outer wall of the instrument 1. One end of the connecting rod 21 is rotatably connected to the sliding block 22, and the other end of the connecting rod 21 is rotatably connected to the push plate 7. The sliding rod 24 is slidably installed on the top of the instrument 1. The connecting rod 23 is rotatably connected to the sliding block 22, and the connecting rod 23 is rotatably connected to the sliding rod 24. The baffle 25 is rotatably installed on the top of the instrument 1, and the collar 26 is fixedly connected to the baffle 25. A slot is provided on the side of the baffle 25 near the sliding rod 24, and an insert rod is slidably installed on the side of the sliding rod 24 near the baffle 25. The insert rod contacts the inner wall of the slot. When the probe 6 is not in use, the baffle 25 is kept closed by the sliding rod 24. This physical barrier can effectively prevent impurities such as dust, water vapor, oil, or corrosive liquids commonly found in chemical sites from entering the interior of the instrument 1 through the opening.

[0050] The cleaning device also includes a ring frame 27, a rotating rod 28, an outer scraper 29, and an inner scraper 291. The ring frame 27 is located on top of the collar 26. The rotating rod 28 is rotatably mounted on the inner wall of the ring frame 27. The outer scraper 29 is rotatably connected to the rotating rod 28. The inner scraper 291 is slidably mounted on the inner wall of the outer scraper 29. Before the probe 6 extends to perform a measurement each time, its surface will automatically make contact with the outer scraper 29 to scrape it. This action can effectively remove residual droplets, condensates, dust, or solid contaminants that may have adhered to the probe 6 after the last use.

[0051] A torsion spring is provided between the baffle 25 and the instrument 1. The torsion spring is provided to drive the baffle 25 to rotate. A torsion spring is provided between the rotating rod 28 and the ring frame 27. The torsion spring is provided to drive the rotating rod 28 to reset. An elastic element is provided between the insert rod and the sliding rod 24. The elastic element is provided to drive the insert rod to move towards the baffle 25. The side of the insert rod near the baffle 25 is set as an inclined surface.

[0052] The auxiliary device includes a sliding table 31, a connecting rod 32, a pressure plate 33, a fixing block 34, and a pressure rod 35. The sliding table 31 is slidably installed on the top of the instrument 1. One end of the connecting rod 32 is fixedly connected to the sliding table 31, and the other end of the connecting rod 32 is fixedly connected to the sliding rod 24. The pressure plate 33 is slidably installed on the inner wall of the sliding table 31. The fixing block 34 is fixedly connected to the pressure plate 33. The pressure rod 35 is slidably installed on the inner wall of the sliding table 31.

[0053] The auxiliary device also includes a fixed frame 36, a key 37, a push block 38, a positioning frame 39, a sliding rod 391, a sliding plate 392, and a sliding key 393. The fixed frame 36 is fixedly installed on the top of the baffle 25. The key 37 slides through the top of the fixed frame 36. The annular frame 27 contacts the inner wall of the fixed frame 36. A slot is provided on the side of the annular frame 27 near the key 37. The key 37 contacts the inner wall of the slot. The push block 38 is slidably connected to the inner wall of the fixed frame 36. The positioning frame 39 is fixedly installed on the instrument 1. At the top, the sliding rod 391 is slidably mounted on the inner wall of the positioning frame 39, the sliding plate 392 is slidably mounted on the top of the instrument 1, and the sliding key 393 slides through the top of the sliding plate 392. A circular groove is provided on the side of the instrument 1 near the sliding plate 392, and the sliding key 393 contacts the inner wall of the circular groove. As long as the baffle 25 is closed normally, its reset process will push the key 37 to release the limit on the ring frame 27, and the push block 38 will push the ring frame 27, so that the entire ring frame 27 assembly can be easily removed.

[0054] The pressure rod 35 has an inclined surface on the side near the fixed block 34. This inclined surface facilitates pressing the fixed block 34 downwards. An elastic element four is provided between the pressure plate 33 and the sliding table 31 to reset the pressure plate 33. An elastic element five is provided between the sliding plate 392 and the instrument 1 to reset the sliding plate 392. An elastic element six is ​​provided between the sliding key 393 and the sliding plate 392 to move the sliding key 393 downwards. The side of block 38 and key 37 that are close to each other is set as an inclined surface. The inclined surface of push block 38 and key 37 is to facilitate push block 38 to push key 37 to move upward. The side of slide rod 391 that is close to slide rod 24 is set as an inclined surface. The inclined surface of slide rod 391 is to facilitate slide rod 24 to push slide rod 391 to move in the direction of slide key 393. The side of slide rod 391 that is close to slide key 393 is set as an inclined surface. The inclined surface of slide rod 391 is to facilitate pushing slide key 393 to move upward.

[0055] In this embodiment, when the push plate 7 moves towards the interior of the instrument 1, it pushes the connecting rod 21 to move. The movement of the connecting rod 21 pushes the sliding block 22 to move, which in turn pushes the connecting rod 23 to move. The movement of the connecting rod 23 pushes the sliding rod 24 to move away from the baffle 25. When the sliding rod 24 moves away from the baffle 25, it releases the obstruction of the baffle 25, allowing the baffle 25 to be rotated away from the sliding groove by the torsion spring 1. The movement of the baffle 25 releases the obstruction of the probe 6, allowing the probe 6 to extend away from the instrument 1. The baffle 25's obstruction of the probe 6 effectively prevents external impurities from entering the instrument 1 through the sliding groove. When the probe 6 is not in use, the baffle 25 remains closed under the action of the sliding rod 24. This physical barrier effectively prevents common chemical site impurities such as dust, water vapor, oil, or corrosive liquids from entering the instrument 1 through the opening, protecting the internal delicate circuits and mechanical structures from contamination and corrosion, greatly improving efficiency. This design enhances the instrument's environmental tolerance and long-term reliability. When the baffle 25 blocks the flow, it moves the collar 26, causing it to align with the sliding groove. The movement of the collar 26 then moves the ring frame 27, which in turn moves the rotating rod 28. The rotating rod 28 then moves the outer scraper 29. As the probe 6 extends away from the instrument 1, its surface contacts the surface of the outer scraper 29, cleaning the probe 6's surface and preventing impurities from adhering to its outer wall during testing, thus ensuring accuracy. Before each measurement, the probe 6 automatically contacts the outer scraper 29, effectively removing any residual droplets, condensates, dust, or solid contaminants that may have adhered to the probe 6 after previous use. This ensures the probe 6 enters the test medium in a clean state, preventing decreased thermal conductivity and delayed temperature response due to probe 6 contamination, thus guaranteeing the accuracy and reliability of each measurement from the source.

[0056] When the sliding rod 24 moves away from the baffle 25, it will drive the connecting rod 32 to move. The movement of the connecting rod 32 will pull the sliding table 31 to move. The movement of the sliding table 31 will drive the pressure plate 33 to move towards the ring frame 27. When the sliding table 31 moves, it will drive the pressure rod 35 to move. When the pressure plate 33 moves towards the top of the ring frame 27, the pressure rod 35 will contact the surface of the collar 26. When the sliding rod 24 drives the connecting rod 32 to continue moving, the pressure rod 35 will move towards the fixed block 34 due to the reaction force applied by the collar 26. The movement of the pressure rod 35 will press the fixed block 34 to move downward. The downward movement of the fixed block 34 will drive the pressure plate 33 to move downward. The downward movement of the pressure plate 33 will clamp the ring frame 27, preventing the ring frame 27 from moving arbitrarily. The downward movement of the pressure plate 33 will tightly press the ring frame 27. This rigid clamping effectively prevents vibration or displacement of the ring frame 27 during cleaning, ensuring the stability and consistency of the contact between the outer scraper 29 and the probe 6 surface. This guarantees the effectiveness and reliability of each cleaning action, avoiding incomplete cleaning or wear of the probe 6 due to component shaking. When the sliding rod 24 moves, it contacts the inclined surface of the sliding rod 391, which pushes the sliding rod 391 towards the sliding plate 392. The movement of the sliding rod 391 then contacts the inclined surface of the sliding key 393. If the sliding lever 391 pushes the sliding key 393 upward, the limit of the sliding key 393 on the sliding plate 392 will be released. Then, when the baffle 25 rotates, the sliding plate 392 can rotate downward without obstructing the baffle 25. When the probe 6 retracts into the instrument 1, the outer scraper 29 will scrape and clean the surface of the probe 6 again. If the outer scraper 29 becomes contaminated by residual liquid on the surface of the probe 6, it needs to be replaced to prevent the contaminated outer scraper 29 from contaminating the surface of the probe 6 during the next use. When the baffle 25 is reset, the collar 26 will also reset. When the baffle 25 moves to its original position, it will drive the fixed frame 36 to move. The movement of the fixed frame 36 will drive the push block 38 to move. The push block 38 will contact the inclined surface of the slide plate 392, and the slide plate 392 will push the push block 38 to move towards the key 37. The push block 38 will then contact the inclined surface of the key 37, and the push block 38 will push the key 37 to move upward. The upward movement of the key 37 will release the limit on the ring frame 27. When the push block 38 continues to move... The ring frame 27 will be pushed to move away from the fixed frame 36, and the ring frame 27 will be disengaged from the fixed frame 36. The ring frame 27 will be directly disassembled during the reset process of the collar 26. When it is necessary to replace the contaminated outer scraper 29, the operator does not need to use any tools or manually unlock the complicated buckles. Just close the baffle 25 normally. Its reset process will push the key 37 to release the limit on the ring frame 27, and the push block 38 will push the ring frame 27, so that the entire ring frame 27 assembly can be easily removed.This disassembly design greatly simplifies the maintenance process, reduces the difficulty and time cost for users to maintain the equipment, and ensures that the equipment can continue to work in the best condition.
