Description

Technical Field

[0001] This utility model relates to the field of temperature measurement equipment technology, and in particular to a temperature control box for temperature measurement. Background Technology

[0002] In numerous fields such as industrial production, scientific research, and healthcare, the accuracy and reliability of temperature measurement play a crucial role. It is not only a prerequisite for ensuring the stable operation of production processes such as chemical reactions and precision manufacturing, but also a core support for ensuring the accurate and repeatable results of scientific research projects such as aerospace material testing and environmental simulation experiments. At the same time, it is directly related to the safe operation and diagnostic and treatment effects of medical equipment such as nuclear magnetic resonance imaging (MRI) machines and autoclaves. It is a fundamental technical pillar for maintaining the efficient operation of the modern industrial system, continuous breakthroughs in scientific research and innovation, and the stability of the public health protection system.

[0003] However, existing temperature measurement chambers fail to form a three-dimensional closed-loop circulation path during use, relying solely on a unidirectional airflow duct. This results in multiple dead zones formed by the inner wall of the chamber during airflow. This structural defect prevents the air inside the chamber from being fully agitated and uniformly mixed. Hot and cold air masses tend to accumulate in local areas, leading to significant temperature stratification. The upper and lower areas, corners, and center areas exhibit obvious temperature differences that exceed the tolerance range of the measurement standard. Consequently, the different measurement sensors, due to differences in their airflow environment, not only reduce the accuracy of synchronous measurement data but also affect the consistency of temperature value transmission. Utility Model Content

[0004] This invention utilizes a temperature control component to achieve efficient and uniform mixing of air within the chamber, effectively eliminating significant temperature differences between the upper and lower areas, corners, and the center. This not only improves the accuracy of synchronous measurement data but also ensures the consistency of temperature value transmission, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a temperature control box for temperature measurement, including a temperature control component;

[0006] A deceleration assembly is disposed on top of the temperature control assembly;

[0010] Preferably, a base is fixedly installed at the bottom of the gas storage tank, and the outer surface of the base is fixedly installed with the rear surface of the housing.

[0011] Preferably, a PLC controller is fixedly installed on the right surface of the enclosure near the corner, and an observation window is provided on the outer surface of the enclosure door.

[0015] 1.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: Refer to Figure 1 - Figure 4 As shown: A temperature control box for temperature measurement, including a temperature control component 1;

[0026] The deceleration component 2 is located on top of the temperature control component 1;

[0027] The temperature control component 1 includes a housing 101 and a gas storage tank 112. A door 102 is movably mounted on the front surface of the housing 101. A set of heating wires 103 are symmetrically fixedly mounted on the inner wall of the housing 101 near the top. A rotating rod 104 is rotatably connected to the top of the housing 101. A set of stirring blades 105 are fixedly mounted on the outer surface of the rotating rod 104. A set of slide rails 106 are symmetrically fixedly mounted on the inner wall of the housing 101 near the center. A placement box 107 is slidably connected to the outer surface of the slide rails 106. A set of honeycomb grooves 108 are formed on the top of the placement box 107. The gas storage tank 1... A gas supply pipe 113 is fixedly connected to the top of the 12. One end of the gas supply pipe 113 slides through the outer surface of the box 101 and extends to one side. A regulating valve 114 is provided on the outer surface of the gas supply pipe 113. A handle 109 is fixedly connected to the outer surface of the placement box 107. A guide plate 110 is fixedly connected to the inner bottom of the box 101. A base 111 is fixedly installed at the bottom of the gas storage tank 112. The outer surface of the base 111 is fixedly installed to the rear surface of the box 101. A PLC controller 115 is fixedly installed on the right surface of the box 101 near the corner. An observation window 116 is provided on the outer surface of the box door 102.

[0028] In this embodiment, during use, first open the door 102, grasp the handle 109 of the placement box 107, and pull it out smoothly. Guided by the sliding rails 106 on both sides inside the box 101, slowly pull out the placement box 107. Then, smoothly place the temperature instrument to be measured into the placement box 107, push the placement box 107 into the box 101, and then close the door 102. At this time, the high-temperature resistant silicone sealing ring on the edge of the door will fit tightly against the box 101, forming a good sealing environment to reduce temperature loss. Then, activate the heating element 1. 03. Initially, the resistance wire will preheat at a higher power. Once the internal temperature approaches the set value, it will automatically switch to a constant temperature power mode. The temperature sensor installed inside the chamber 101 will monitor the internal temperature in real time at high frequency and transmit the data to the PLC controller 115. When the detected temperature exceeds the set threshold by a small margin, the PLC controller 115 will activate the regulating valve 114, opening the passage connected to the gas storage tank 112. The inert gas pre-stored in the gas storage tank 112 will be transported to the inside of the chamber 101 through the gas supply pipe 113. The inert gas enters the chamber 101. At time 1, the gas will first come into contact with the guide plate 110 inside the chamber 101. The guide plate 110 guides the low-temperature inert gas smoothly to both sides of the chamber 101 by changing the gas flow direction, effectively avoiding the gas directly impacting the temperature measuring instrument and causing excessive local temperature difference. At the same time, the honeycomb grooves 108 set in the placement box 107 will further divide the airflow during the gas diffusion process, promoting the formation of multi-directional convection of air inside the chamber. In conjunction with the rotation of the stirring blade 105 driven by the rotating rod 104, the temperature in different areas of the chamber will quickly become uniform. In addition, the chamber door 102 is equipped with a viewing device. The observation window 116 allows for clear observation of the internal instrument status and temperature changes. The nano anti-fog coating on the inside of the observation window 116 effectively prevents fogging caused by temperature differences between the inside and outside from affecting visibility, thereby reducing temperature fluctuations inside the chamber caused by frequent opening of the door for observation. Under the action of the temperature control component 1, the air inside the chamber is efficiently and evenly mixed, effectively eliminating significant temperature differences between the upper and lower areas, corners and the center area. This not only improves the accuracy of synchronous measurement data, but also ensures the consistency of temperature value transmission. The base 111 is mainly used to stabilize and fix the gas storage tank 112.

[0029] Example 2: According to Figure 1 - Figure 5 As shown: The reduction assembly 2 includes a mounting plate 201. A servo motor 202 is fixedly mounted on the top of the mounting plate 201. The output end of the servo motor 202 slides through the top of the mounting plate 201 and extends downward. A drive gear 203 is fixedly mounted on the output end of the servo motor 202. A driven gear 204 is meshed with the outer surface of the drive gear 203. The bottom of the drive gear 203 and the driven gear 204 are rotatably connected to the top of the housing 101. The bottom of the mounting plate 201 is fixedly mounted to the top of the housing 101. The bottom of the driven gear 204 is fixedly mounted to the top of the rotating rod 104.

[0030] In this embodiment, during use, the servo motor 202 on the mounting plate 201 is started, and its output end drives the drive gear 203 to rotate. During the rotation of the drive gear 203, the driven gear 204 is driven to rotate. Since the diameter of the drive gear 203 is smaller than that of the driven gear 204, the driven gear 204 can reduce speed when it rotates. The slow rotation of the driven gear 204 drives the rotating rod 104 to rotate slowly. Under the action of the deceleration component 2, it can avoid the formation of eddies due to the violent disturbance of the airflow inside the box caused by the excessive rotation speed, which would cause local temperature fluctuations. At the same time, it can prevent the high-speed airflow from directly impacting the temperature measuring instrument and affecting its stability, ensuring that the temperature field always remains stable and uniform.

[0031] Working principle: In use, first, open the chamber door 102, grasp the handle 109 of the placement box 107, and slowly pull it out using the slide rails 106 on both sides inside the chamber 101. After placing the temperature instrument to be measured, push it back into the chamber, close the chamber door 102. The high-temperature resistant silicone sealing ring on the edge of the door will tightly fit the chamber 101 to reduce heat loss. Start the heating element 103 to preheat at a higher power initially. When the temperature approaches the set temperature, switch to constant temperature mode. The temperature sensor inside the chamber monitors the temperature at high frequency and transmits it to the PLC controller 115. When the temperature slightly exceeds the set threshold, the controller activates the regulating valve 114. The inert gas in the gas tank 112 enters the chamber 101 through the gas pipe 113 and is then introduced... The guide plate 110 guides the two sides to avoid direct impact on the instrument. At the same time, the honeycomb groove 108 of the placement box 107 divides the airflow to promote convection. The servo motor 202 is started, and its output end drives the active gear 203 to rotate, which in turn drives the driven gear 204 with a larger diameter. Through the deceleration effect, the rotating rod 104 rotates slowly. The rotating rod 104 drives the stirring blade 105 to rotate slowly to make the temperature uniform. In addition, the observation window 116 of the box door 102 facilitates observation. The inner nano anti-fog coating prevents fog from affecting the vision and reduces the number of times the door is opened. Its output end drives the active gear 203 to rotate, which in turn drives the driven gear 204 with a larger diameter. Through the deceleration effect, the rotating rod 104 rotates slowly.

[0032] By following the steps outlined above, you can complete the use of the temperature control box for temperature measurement.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
