Technical Field

[0001] This invention relates to the field of temperature sensor detection technology, and in particular to a temperature sensor response speed testing device. Background Technology

[0002] In the field of heated cigarette quality control, accurate measurement of key parameters such as smoke temperature, heating element temperature, and cigarette device temperature is crucial for product development and quality control. However, traditional thermocouples and platinum resistance temperature sensors have unclear response time characteristics, which can lead to significant deviations in the measurement data of key parameters such as smoke temperature and cigarette surface temperature during smoking. Therefore, the response speed of temperature sensors is measured before use to select temperature sensors that meet the requirements.

[0003] Currently, the response speed of temperature sensors is typically measured by quickly placing the sensor into a temperature calibration furnace and then detecting the instantaneous temperature changes inside and outside the furnace. However, during testing, it's impossible to guarantee the consistent placement of the temperature sensor within the furnace. Although the temperature differences between different parts of the furnace are small, this can still introduce errors into the measurement results. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An embodiment of this utility model provides a temperature sensor speed testing device, including a base, a support rod provided on the upper surface of the base, the support rod being vertically arranged, a cylinder being fixed on the support rod by an adjustment device, and a temperature sensor being fixedly connected to the end of the telescopic rod of the cylinder. The adjusting device includes a first pipe clamp and a second pipe clamp. Both the first pipe clamp and the second pipe clamp are sleeved on the support rod and are detachably connected to the support rod. The first pipe clamp is rotatably connected to the end of the cylinder barrel. Two limiting plates are arranged in parallel on the second pipe clamp. The cylinder is located between the two limiting plates. The front ends of the cylinder barrel are slidably connected to the two limiting plates respectively.

[0006] Furthermore, a temperature calibration furnace is placed on one side of the base, and the cylinder is fixed above the temperature calibration furnace by an adjustment device.

[0007] Furthermore, the first pipe clamp has a C-shaped structure, is sleeved on the outside of the support rod, and the inner wall of the first pipe clamp is in contact with the outer surface of the support rod. The two sides of the opening of the first pipe clamp are connected by hand-tightened bolts.

[0008] Furthermore, a connecting seat is fixed on the first pipe clamp, and a shaft hole is opened on the connecting seat. Ear plates are provided on both sides of the end of the cylinder barrel, and the distance between the two ear plates is equal to the width of the connecting seat. The connecting seat is located between the two ear plates, and the connecting seat and the two ear plates are rotatably connected by a rotating shaft.

[0009] Furthermore, both limiting plates are provided with sliding holes, which are symmetrically arranged. The sliding holes are elongated holes opened in the horizontal direction. Connecting rods are provided on both sides of the front end of the cylinder barrel. The connecting rods are perpendicular to the limiting plates and are adapted to the sliding holes. The connecting rods are slidably connected to the sliding holes. Furthermore, a guide seat is provided on one side of the front end of the cylinder barrel, and a guide rod is provided on the guide seat. The end of the cylinder telescopic rod is connected to the end of the guide rod through a connecting plate, and the temperature sensor is fixed on the connecting plate.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] A typical embodiment of this utility model is as follows: Figure 1 As shown, a temperature sensor response speed testing device includes a base 1, a support rod 2 is provided on the upper surface of the base 1, the support rod 2 is vertically arranged, a cylinder 3 is fixed on the support rod 2 by an adjustment device, and a temperature sensor 4 is fixedly connected to the end of the telescopic rod of the cylinder 3. The height and swing angle of the temperature sensor 4 can be adjusted by the adjustment device.

[0019] A temperature calibration furnace 5 is placed on one side of the base 1. The cylinder 3 is fixed above the temperature calibration furnace 5 by an adjustment device. When the extension rod of the cylinder 3 extends, it can drive the temperature sensor 4 into the temperature calibration furnace 5. By setting the adjustment device, it can be ensured that the temperature sensor 4 accurately enters the specific position of the temperature calibration furnace 5, ensuring good contact between the temperature sensor 4 and the temperature field inside the furnace, thereby minimizing the measurement error caused by external factors.

[0020] In this embodiment, the temperature calibration furnace 5 is a common dry temperature calibration furnace on the market, which can provide a stable, uniform, and accurate temperature field.

[0021] like Figure 2As shown, the adjustment device includes a first pipe clamp 6 and a second pipe clamp 7. Both the first pipe clamp 6 and the second pipe clamp 7 are sleeved on the support rod 2 and are detachably connected to the support rod 2. Both the first pipe clamp 6 and the second pipe clamp 7 can slide along the support rod 2. At the same time, the first pipe clamp 6 and the second pipe clamp 7 can be fixed at any height of the support rod 2 as needed.

[0022] The first pipe clamp 6 and the second pipe clamp 7 have the same structure. Here, only the structure of the first pipe clamp 6 will be described. The first pipe clamp 6 has a C-shaped structure and can be sleeved on the outside of the support rod 2. The inner wall of the first pipe clamp 6 is in contact with the outer surface of the support rod 2. The two sides of the opening of the first pipe clamp 6 are connected by hand-tightening bolts. When the hand-tightening bolts are tightened, the two sides of the opening of the first pipe clamp 6 move closer to each other, thereby clamping the support rod 2 and realizing the fixed connection between the first pipe clamp 6 and the support rod 2. When the hand-tightening bolts are loosened, the first pipe clamp 6 can slide along the support rod 2, thereby adjusting the height of the first pipe clamp 6.

[0023] The first pipe clamp 6 is located above the second pipe clamp 7. The first pipe clamp 6 is rotatably connected to the end of the cylinder barrel of the cylinder 3, so that the cylinder 3 can swing around the first pipe clamp 6. Specifically, a connecting seat 8 is fixed on the first pipe clamp 6. The connecting seat 8 is provided with a shaft hole. Ear plates 9 are provided on both sides of the end of the cylinder barrel of the cylinder 3. The distance between the two ear plates 9 is equal to the width of the connecting seat 8. By placing the connecting seat 8 between the two ear plates 9 and passing the rotating shaft through the two ear plates 9 and the connecting seat 8, the rotatable connection between the first pipe clamp 6 and the cylinder 3 is achieved.

[0024] Two limiting plates 10 are arranged in parallel on the second pipe clamp 7. The distance between the two limiting plates 10 is greater than the diameter of the cylinder barrel of the cylinder 3, so that the cylinder 3 can be placed between the two limiting plates 10. Each of the two limiting plates 10 is provided with a sliding hole 11. The two sliding holes 11 are arranged symmetrically. The sliding hole 11 is an elongated hole opened in the horizontal direction. Connecting rods are provided on both sides of the front end of the cylinder barrel of the cylinder 3. The connecting rods are perpendicular to the limiting plates 10. The connecting rods are adapted to the sliding holes 11. The connecting rods can be inserted into the sliding holes 11 and can slide along the sliding holes 11.

[0025] In use, first fix the position of the first pipe clamp 6 according to the height of the temperature calibration furnace 5, so that the cylinder 3 is above the temperature calibration furnace 5. Since the end of the cylinder 3 is rotatably connected to the first pipe clamp 6, the cylinder 3 can swing around the first pipe clamp 6, thereby adjusting the angle of the temperature sensor 4 so that the temperature sensor 4 can be aligned with the inlet of the temperature calibration furnace 5.

[0026] When adjusting the angle of temperature sensor 4, the connecting rod slides in the sliding hole 11, and at the same time drives the second pipe clamp 7 to slide along the support rod 2. After the angle of temperature sensor 4 is adjusted, the second pipe clamp 7 is fixed to the support rod 2 by the hand-tightening bolt on the second pipe clamp 7. At this time, the limiting plate 10 and the connecting rod support the cylinder barrel of cylinder 3, and at the same time, the limiting plate 10 and the connecting rod limit the cylinder barrel of cylinder 3 to fix the angle of temperature sensor 4.

[0027] Furthermore, a guide seat 12 is provided on one side of the front end of the cylinder barrel of cylinder 3, and a guide rod 13 is provided on the guide seat 12. The end of the cylinder 3 telescopic rod is connected to the end of the guide rod 13 through a connecting plate 14. The temperature sensor 4 is fixed on the connecting plate 14. By setting the guide seat 12 and the guide rod 13, the stability of cylinder 3 during telescopic movement can be ensured.

[0028] A support platform 15 is also provided on the base 1. The support platform 15 is fixed above the base 1 by the support frame 16 and is located on one side of the support rod 2. An industrial control computer 17 is provided on the support platform 15. In this embodiment, the industrial control computer 17 adopts a PLC controller. The industrial control computer 17 is electrically connected to the solenoid valve controlling the cylinder 3 and the temperature sensor 4 respectively. The industrial control computer 17 controls the extension and retraction of the cylinder 3 through the solenoid valve. The temperature sensor 4 sends the detected temperature data to the industrial control computer 17 in real time. The industrial control computer 17 determines the response speed of the temperature sensor 4 according to its pre-programmed program.

[0029] The industrial control computer 17 determines the response speed of the temperature sensor 4 based on the temperature data detected by the temperature sensor 4, which is existing technology and will not be described in detail here.

[0030] Cylinder 3 is connected in sequence to a solenoid valve, a pressure regulating valve, and an air compressor via an air pipe. The air compressor provides compressed air to cylinder 3, serving as its power source. The pressure regulating valve ensures the stability of the air pressure. The solenoid valve is electrically connected to the industrial control computer 17 and can control the extension and retraction of the cylinder 3's telescopic rod. Speed ​​regulating valves are installed on the air pipes connecting the solenoid valve to both the rod chamber and the rodless chamber of cylinder 3 to control the extension and retraction speeds of cylinder 3.

[0031] The speed control valve is a common speed regulating valve on the market. It controls the extension and retraction speed of cylinder 3 by controlling the flow rate of gas entering cylinder 3. In the fast response test, it can ensure that cylinder 3 completes the sensor entry and exit operation in a short time to simulate instantaneous temperature change. In the slow response test, the gas flow rate can be reduced to reduce the action speed of cylinder 3 to simulate long-term, slow temperature change.

[0032] In use, first fix the temperature sensor 4 on the connecting plate 14 at the end of the telescopic rod of the cylinder 3, and adjust the height and angle of the cylinder 3 through the adjustment device so that the temperature sensor 4 can be correctly inserted into the test position of the temperature calibration furnace 5. According to the test requirements, set the telescopic speed of the cylinder 3 through the speed control valve. Turn on the industrial control computer 17 and the temperature calibration furnace 5. Under the control of the industrial control computer 17, the telescopic rod of the cylinder 3 extends rapidly and drives the temperature sensor 4 into the temperature calibration furnace 5. The temperature sensor 4 monitors the temperature inside the temperature calibration furnace 5 in real time and transmits the measurement data to the industrial control computer 17. The industrial control computer 17 determines the response speed of the temperature sensor 4 based on the measurement data.

[0033] The cylinder is fixed to the support rod by the first and second pipe clamps, both of which are detachably connected to the support rod and can slide along the support rod. The first and second pipe clamps can be fixed at any height on the support rod as needed, thereby adjusting the cylinder position. Furthermore, the first pipe clamp is rotatably connected to the end of the cylinder barrel, and the second pipe clamp is slidably connected to the front end of the cylinder barrel via a limiting plate, allowing for adjustment and fixation of the cylinder angle. By setting an adjustment device, the temperature sensor can be accurately positioned within the temperature calibration furnace, ensuring good contact between the temperature sensor and the temperature field inside the furnace, thus minimizing measurement errors caused by external factors.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
