Description

Technical Field

[0001] This application relates to the technical field of temperature and humidity environment chamber equipment, and in particular to a temperature and humidity environment chamber with adjustable air inlet and outlet. Background Technology

[0002] Temperature and humidity chambers are testing equipment that simulates different temperature and humidity environments. They are widely used in product performance testing in industries such as electronics, materials, and food. By controlling the temperature and humidity parameters inside the chamber, they provide environmental conditions that meet testing standards for the products.

[0003] Traditional temperature and humidity chambers typically have fixed air inlets and outlets, making it difficult to flexibly adjust the direction of airflow. If it is necessary to change the airflow direction to suit different test samples or test requirements, it is often necessary to disassemble the chamber panel and replace the air guide accessories, which is cumbersome and time-consuming. Some temperature and humidity chambers with adjustable airflow have complex adjustment structures, often with multiple components controlled independently, making it difficult to control the adjustment accuracy. Furthermore, the numerous operating steps reduce the ease of use of the equipment. Summary of the Invention

[0004] To improve the ease of operation of temperature and humidity environment chambers with adjustable air inlets and outlets, this application provides a temperature and humidity environment chamber with adjustable air inlets and outlets.

[0005] This application provides a temperature and humidity environment chamber with adjustable air inlet and outlet, employing the following technical solution: An adjustable temperature and humidity environment chamber includes a chassis, a ventilation box installed inside the chassis, an air outlet panel and a return air panel installed on the ventilation box, the air outlet panel and the return air panel being arranged opposite to each other, an air exchange component for controlling the flow of gas within the ventilation box installed on the chassis, and an adjustment component for adjusting the airflow direction installed inside the ventilation box.

[0006] By adopting the above technical solution, the ventilation components are used to realize the circulation of air and the regulation of temperature and humidity in the ventilation box. The air flow direction can be adjusted directly in the ventilation box through the adjustment components without disassembling the box accessories, which simplifies the operation steps of air direction adjustment and effectively improves the operation convenience of the temperature and humidity environment chamber. The air outlet panel and the air return panel are set opposite to each other to ensure the air circulation efficiency in the ventilation box and adapt to the test requirements of the temperature and humidity environment chamber.

[0007] In one specific implementation, the air outlet panel is provided with air outlet holes, and the return air panel is provided with return air holes. The air outlet holes on the air outlet panel and the return air holes on the return air panel are respectively arranged opposite to each other.

[0008] By adopting the above technical solution, the air outlet and return air outlet are set one-to-one, so that the airflow blown out from the air outlet panel can flow back from the return air panel along the corresponding path, ensuring the regularity of airflow circulation in the ventilation box. At the same time, it is convenient for the adjustment components to accurately control the airflow direction and improve the effect of airflow adjustment.

[0009] In one specific implementation, the air outlet panel and the air return panel are each composed of two or more panels joined together.

[0010] By adopting the above technical solutions, the spliced ​​air outlet and return air panels are easy to disassemble, replace and maintain. If a single panel or part of the air outlet or return air hole is damaged, only the corresponding spliced ​​panel can be replaced, which reduces the maintenance cost of the equipment. At the same time, spliced ​​panels with different air outlet and return air hole specifications can be replaced according to the testing requirements, which improves the adaptability of the equipment.

[0011] In one specific implementation scheme, the adjusting assembly includes a vertical plate mounted on the ventilation box, a guide plate rotatably mounted on the vertical plate, a base plate mounted on the ventilation box, a telescopic sleeve mounted on the base plate, a telescopic rod slidably connected to the telescopic sleeve, a lifting sleeve mounted on the telescopic rod, a first spring sleeved on the telescopic rod, and a movable rod slidably mounted on the lifting sleeve; a base platform for controlling the movement of the movable rod is mounted on the base plate, the base platform has a beveled surface, a cylinder is installed inside the ventilation box, the output shaft of the cylinder is connected to a push plate, the push plate abuts against the movable rod, a support rod is mounted on the lifting sleeve, a second sliding groove is formed on the guide plate, the support rod passes through the second sliding groove and is slidably connected to the guide plate, and a first lever is mounted on the support rod, the first lever being located on both sides of the guide plate.

[0012] By adopting the above technical solution, a cylinder drives a push plate to move a movable rod. When the movable rod moves along the inclined plane of the base, it achieves vertical lifting and lowering, which in turn drives the lifting sleeve and the support rod to lift and lower synchronously. The support rod moves the air guide plate around the vertical plate through the first lever, thereby adjusting the vertical airflow. The cooperation between the telescopic sleeve and the telescopic rod provides guidance for the lifting and lowering of the lifting sleeve. The first spring can realize the reset of the lifting sleeve, making the adjustment and reset operation of the air guide plate smoother. The entire adjustment structure is driven by a cylinder, which is simple to operate and the adjustment accuracy is easy to control.

[0013] In one specific implementation, a first sliding groove is provided on the base platform, and a roller is rotatably mounted on the movable rod. The roller extends into the first sliding groove and is able to roll on the base platform.

[0014] By adopting the above technical solution, the roller converts the sliding friction between the movable rod and the base into rolling friction, reducing the resistance when the movable rod moves, making the movement of the movable rod along the inclined plane smoother, avoiding jamming, and improving the smoothness of wind direction adjustment; the first slide groove limits the movement of the roller to prevent the movable rod from deviating and ensures the accuracy of the movement of the movable rod.

[0015] In one specific implementation scheme, an mounting strip is installed on the upright plate, and an air guide plate is hinged to the mounting strip. A third sliding groove is formed at the end of the air guide plate away from the mounting strip. A pusher is slidably installed on the air guide plate, and the pusher passes through the third sliding groove. A second lever is installed on the pusher, and the second lever is located on both sides of the air guide plate. A second spring is connected to one end of the pusher, and the end of the second spring away from the pusher is connected to the upright plate. A fixed rod is installed on the base platform, and a sliding sleeve is slidably installed on the fixed rod. A swing rod is hinged to the movable rod, and the end of the swing rod away from the movable rod is hinged to the sliding sleeve. A push block is installed on the sliding sleeve, and an inclined surface is formed on the push block. The end of the pusher near the push block abuts against the inclined surface of the push block.

[0016] By adopting the above technical solution, when the movable rod moves, it drives the swing rod to swing. The swing rod pushes the sliding sleeve to slide along the fixed rod. The sliding sleeve drives the push block to move synchronously. The push block pushes the push strip to move horizontally through the inclined surface. The push strip moves the air guide plate around the mounting strip through the second lever, thereby adjusting the left and right airflow direction. The second spring can reset the push strip, making the adjustment operation of the air guide plate more convenient. This structure is linked with the adjustment structure of the air guide plate and driven by the same cylinder, realizing the synchronous adjustment of the airflow direction in the up and down and left and right directions, further simplifying the operation steps and improving the ease of use of the equipment.

[0017] In one specific implementation, the end of the push bar that abuts against the push block is configured as a spherical shape.

[0018] By adopting the above technical solution, the ball-shaped end reduces the frictional resistance between the pusher and the inclined surface of the pusher block, making the pusher block push the pusher block move more smoothly, while avoiding jamming between the end of the pusher block and the inclined surface, thus ensuring the stability of left and right wind direction adjustment.

[0019] In one specific implementation, the ventilation assembly includes a ventilation box mounted on the chassis. A partition is installed on the bottom surface of the ventilation box, and the end of the partition away from the ventilation box is connected to the ventilation box. A fan is installed on the ventilation box, and the fan is located on the side of the partition near the return air panel. A hole for ventilation to the fan is opened on the bottom surface of the ventilation box, and a temperature and humidity module is installed inside the ventilation box.

[0020] By adopting the above technical solution, the fan draws air from the return air panel side of the ventilation box through the holes. After the air enters the ventilation box, the temperature and humidity are regulated by the temperature and humidity module. The partition separates the return air area and the outlet air area in the ventilation box, preventing the unregulated air from flowing back directly and ensuring the effect of temperature and humidity regulation. The regulated air flows into the outlet air panel side of the ventilation box, realizing the circulation and temperature and humidity regulation of the air. The entire ventilation component has a simple structure and high airflow circulation efficiency.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. This application achieves air circulation temperature and humidity regulation and airflow direction regulation by setting an adjustment component in the ventilation box, in conjunction with the ventilation component. The airflow direction can be adjusted without disassembling the box parts, which simplifies the operation steps and effectively improves the ease of operation of the temperature and humidity environment box. Moreover, the adjustment component is driven by a cylinder, realizing the linkage adjustment of the airflow direction in the up and down and left and right directions. The adjustment accuracy is easy to control and the operation is simpler.

[0022] 2. By setting the air outlet and return air outlet one-to-one, the regularity of airflow circulation in the ventilation box is ensured, which makes it easy for the adjustment components to accurately control the airflow direction; the spliced ​​air outlet and return air panels are easy to disassemble and maintain, reducing the maintenance cost of the equipment and improving the adaptability of the equipment.

[0023] 3. The adjustment component of this application is equipped with a first spring and a second spring, which respectively realize the reset of the air guide plate and the air guide vane. The frictional resistance between the components is reduced by the roller, ball-shaped end and other structures, so as to avoid jamming and ensure the smoothness and stability of the air direction adjustment. The ventilation component is equipped with a baffle to separate the return air area and the air outlet area, so as to prevent the direct backflow of air without temperature and humidity adjustment and ensure the effect of temperature and humidity adjustment.

The temperature and humidity module 33 consists of a spray pipe and a heating rod. The spray pipe is connected to a water source, and the heating rod is an electric heating rod.

[0036] When using the temperature and humidity environment chamber, the fan 32 starts to draw air from one side of the return air panel 22 to create airflow. The air is drawn into the ventilation box 31, passes through the temperature and humidity module 33, and the temperature and humidity of the air are increased by the temperature and humidity module 33. Then it flows into one side of the outlet air panel 21 and from the outlet air panel 21 into the ventilation box 2. After circulating and staying in the ventilation box 2, the air is drawn out from one side of the return air panel 22 by the fan 32 to enter the next cycle.

[0037] Reference Figure 4 , Figure 5 and Figure 6 An airflow adjustment assembly 4 is installed inside the ventilation box 2 near the air outlet panel 21 and the return air panel 22. The adjustment assembly 4 includes a vertical plate 41, which is fixedly installed on the ventilation box 2. An air guide plate 42 is rotatably installed on the vertical plate 41.

[0038] Reference Figure 6 and Figure 7 A base platform 437 is fixedly installed on the base plate 431. The base platform 437 has a beveled surface 4371 and a first sliding groove 4372. A roller 4361 is rotatably mounted on the movable rod 436, extending into the first sliding groove 4372 and rolling on the base platform 437. A cylinder 439 is fixedly installed inside the ventilation box 2. A push plate 4391 is fixedly connected to the output shaft of the cylinder 439, and the push plate 4391 abuts against the movable rod 436.

A first lever 4381 is fixedly installed on the support rod 438, and the first lever 4381 is located on both sides of the air guide plate 42.

[0039] When it is necessary to adjust the concentrated flow direction of the air blown into or out of the ventilation box 2, the cylinder 439 controls the push plate 4391 to move, the push plate 4391 pushes the movable rod 436 to move, and through the action of the inclined surface 4371 on the base 437, the movable rod 436 will move upward, thereby the movable rod 436 drives the lifting sleeve 434 to move upward, the lifting sleeve 434 drives the support rod 438 to move upward, and the first lever 4381 is used to make the air guide plate 42 swing, thereby changing the vertical flow direction of the air.

[0040] Reference Figure 5 , Figure 6 and Figure 7 An installation strip 441 is fixedly installed on the upright plate 41. A guide vane 442 is hinged to the installation strip 441. A third sliding groove 4421 is opened at the end of the guide vane 442 away from the installation strip 441. A pusher 443 is slidably installed on the guide vane 442, passing through the third sliding groove 4421. A second lever 4431 is fixedly installed on the pusher 443, and the second lever 4431 is located on both sides of the guide vane 442. A second spring 444 is fixedly connected to one end of the pusher 443, and the end of the second spring 444 away from the pusher 443 is fixedly connected to the upright plate 41. A fixing rod 445 is fixedly installed on the base platform 437. A sliding sleeve 446 is slidably installed on the fixing rod 445. A swing rod 447 is hinged to the movable rod 436, and the end of the swing rod 447 away from the movable rod 436 is hinged to the sliding sleeve 446. A push block 448 is fixedly mounted on the sliding sleeve 446. The push block 448 has an inclined surface. One end of the push strip 443 near the push block 448 abuts against the inclined surface of the push block 448. The end of the push strip 443 that abuts against the push block 448 is shaped like a ball. In this embodiment, a connecting plate 449 for connecting adjacent sliding sleeves 446 is fixedly connected to the sliding sleeve 446.

[0041] When the movable rod 436 moves, it drives the swing rod 447 to move. The swing rod 447 pushes the sliding sleeve 446 to slide on the fixed rod 445. The sliding sleeve 446 drives the push block 448 to move. Through the action of the inclined surface on the push block 448, the push block 448 pushes the push bar 443 to move, thereby causing the second lever 4431 to drive the air guide vane 442 to swing, changing the left and right flow direction of the air.

[0042] The implementation principle of this application embodiment is as follows: When using the temperature and humidity environment chamber, the test sample is first placed in the ventilation chamber 2, the casing 1 is closed, and the fan 32 and the temperature and humidity module 33 are started. The fan 32 draws air from the side of the return air panel 22 in the ventilation chamber 2 through the holes on the bottom surface of the ventilation chamber 31. After the air enters the return air area of ​​the ventilation chamber 31, it flows through the temperature and humidity module 33 to complete the temperature and humidity adjustment. The adjusted air enters the air outlet area of ​​the ventilation chamber 31, and then flows into the side of the air outlet panel 21 in the ventilation chamber 2. It is blown into the test chamber of the ventilation chamber 2 from the air outlet 211. After the air circulates in the chamber, it flows back from the return air hole 221 to achieve continuous temperature and humidity environment simulation.

[0043] When it is necessary to adjust the vertical airflow direction in the ventilation box 2, the cylinder 439 is activated. The output shaft of the cylinder 439 extends and pushes the push plate 4391 to move. The push plate 4391 pushes the movable rod 436 to move horizontally along the lifting sleeve 434. The roller 4361 on the movable rod 436 rolls along the first slide groove 4372 of the base platform 437 and moves upward along the inclined surface 4371, causing the movable rod 436 and the lifting sleeve 434 to rise vertically along the telescopic rod 433. The first spring 435 is compressed. The lifting sleeve 434 drives the support rod 438 to rise. The support rod 438, through the first lever 4381, moves the air guide plate 42 to rotate around the vertical plate 41 in the vertical plane, changing the tilt angle of the air guide plate 42, thereby adjusting the vertical airflow direction. The reverse start cylinder 439 retracts the output shaft, the push plate 4391 separates from the movable rod 436, the first spring 435 returns to its natural extended state, driving the lifting sleeve 434 and the movable rod 436 to reset, and the air guide plate 42 also resets accordingly.

[0044] When it is necessary to adjust the left and right airflow direction in the ventilation box 2, the movable rod 436 moves horizontally, driving the swing rod 447 to swing around the hinge. The swing rod 447 pushes the sliding sleeve 446 to rise vertically along the fixed rod 445. The sliding sleeve 446 drives the push block 448 to rise synchronously. The push block 448 pushes the push bar 443 to move horizontally through the inclined surface, and the second spring 444 is stretched. The push bar 443 moves the air guide vane 442 around the hinge of the mounting strip 441 in the horizontal plane through the second lever 4431, changing the tilt angle of the air guide vane 442, thereby realizing the adjustment of the left and right airflow direction. When the movable rod 436 returns to its original position, the push block 448 descends with the sliding sleeve 446, the second spring 444 returns to its natural extended state, driving the push bar 443 to return to its original position, and the air guide vane 442 also returns to its original position.

[0045] The adjustment structure of the air guide plate 42 and the air guide vane 442 is driven by the same cylinder 439, realizing the linkage adjustment of the air flow direction in the up and down and left and right directions. There is no need to operate multiple driving components separately, which effectively improves the ease of operation. Moreover, the entire adjustment process does not require disassembling the box accessories, and the operation steps are simple.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
