Description

Technical Field

[0001] This utility model relates to the field of environmental testing technology, and in particular to a gas delivery device and an aging test chamber. Background Technology

[0002] Aging test chambers are a general term for equipment used in the environmental testing industry to conduct artificial climate accelerated aging tests on materials. They cover test methods such as ultraviolet aging, xenon lamp aging, ozone aging, high temperature aging, and salt spray corrosion aging. They are widely used in the fields of electronics, automobiles, aerospace, plastics and rubber to evaluate the weather resistance, corrosion resistance and reliability of materials.

[0003] The main body of an aging test chamber is generally made of stainless steel, with an internal insulation layer and a circulating air supply system to ensure uniform temperature inside the chamber. It is also equipped with an ultraviolet or xenon lamp lighting system to simulate light radiation and alternating heat and humidity to accelerate material aging. Existing circulating air supply systems in test chambers are mostly vertical air ducts, using multiple air outlets along the vertical direction to deliver air to each test compartment. However, existing air supply systems cannot adjust the airflow and direction of individual air outlets from the end; operators can only adjust them from the initial end of the system (i.e., the fan), making operation complex and unable to achieve individual air supply control within the test compartment. Utility Model Content

[0004] The purpose of this invention is to provide a gas delivery device that is simple in structure, easy to operate, and can meet the diverse needs of aging tests.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Gas conveying device, including:

[0007] The air duct is used to circulate air, and a plurality of air supply hole groups are spaced apart along the length direction of the air duct, each air supply hole group including at least one air outlet.

[0008] The regulating mechanism includes multiple air volume regulating plates and multiple air direction regulating components. The air volume regulating plates are tunably connected to the air duct, and the multiple air volume regulating plates are arranged in a one-to-one correspondence with the multiple air supply hole groups. The air volume regulating plates have an outlet that matches the size of the air supply port. The outlet is positioned directly opposite the air supply port. The air volume regulating plates can be moved relative to the air duct to cover the air supply port.

[0009] Multiple airflow adjustment components are arranged in a one-to-one correspondence with multiple air outlet groups. Each airflow adjustment component includes a mounting bracket and a guide vane rotatably mounted on the mounting bracket. The mounting bracket is connected to the air duct. The guide vane is located on the side of the airflow adjustment plate opposite to the air outlet, facing the outlet. The guide vane is used to guide the airflow direction.

[0010] Preferably, each of the air supply hole groups includes a plurality of air supply outlets.

[0011] Preferably, the air volume regulating plate has a waist-shaped hole, and the bolt passing through the waist-shaped hole fixes the air volume regulating plate and the air duct.

[0012] Preferably, each of the wind direction adjustment components includes a plurality of parallel-arranged guide vanes, which are evenly connected to the mounting frame at intervals.

[0013] Preferably, the wind direction adjustment component further includes a linkage rod, which is sequentially connected to a plurality of the guide vanes. Rotation of one of the guide vanes can drive the linkage rod to move, thereby driving the other guide vanes to rotate accordingly.

[0014] Preferably, the wind direction adjustment assembly further includes an adjustment motor, which is fixedly mounted on the mounting bracket, and the output end of the adjustment motor is connected to any of the guide vanes.

[0015] Preferably, the mounting bracket is detachably mounted on the airflow regulating plate.

[0016] An aging test chamber includes a fan, a test chamber body, and the aforementioned gas delivery device. The air duct is connected to the test chamber body, and each of the air supply hole groups is positioned opposite to the test space of each layer of the test chamber body. The fan is used to blow airflow into the air duct.

[0017] The beneficial effects of this utility model are as follows:

[0018] The gas delivery device provided by this utility model includes an air duct and an adjustment mechanism. Since the air duct is used for air circulation, and multiple air supply hole groups are spaced apart along its length, with each air supply hole group including at least one air outlet, the air duct can be connected to an air source to deliver air to each test compartment in the aging test chamber. An outlet matching the size of the air supply outlet is provided on the air volume adjustment plate. Since the outlet is directly opposite the air supply outlet, under normal circumstances, the air in the air duct can be blown out sequentially through the air supply outlet and the outlet. Because the air volume adjustment plate is adjustablely connected to the air duct, when… When the airflow regulating plate moves relative to the air duct, the outlet and the air supply outlet are misaligned. The regulating plate then partially covers the air supply outlet, allowing adjustment of the airflow rate. This continues until the outlet and air supply outlet are completely misaligned and no longer overlap, at which point the regulating plate completely blocks the air supply outlet, closing it. The airflow direction regulating component's guide vanes are mounted to the air duct via a mounting bracket. Because the guide vanes are positioned directly opposite the outlet and can rotate, operators can change the airflow direction according to test requirements. This gas delivery device has a simple structure, enabling independent air supply to each layer of the aging test chamber. Furthermore, the airflow rate and direction of each air supply outlet can be adjusted as needed, greatly improving the flexibility and practicality of the test.

[0019] The aging test chamber provided by this utility model includes a fan, a test chamber body, and the aforementioned gas delivery device. The fan can blow airflow into each independent space inside the test chamber through the gas delivery device to meet the requirements of the aging test. Furthermore, the aging test chamber can adjust the airflow volume and direction of each independent space inside the test chamber individually, thereby meeting the requirements of aging comparison tests under different working conditions and further improving the diversity and accuracy of the test.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0029] like Figure 1 and Figure 2As shown, this utility model provides a gas conveying device, which includes a duct 1 and an adjusting mechanism 2. The duct 1 is used for air circulation, and multiple air supply hole groups are spaced apart along the length of the duct 1. Each air supply hole group includes at least one air outlet 11. The adjusting mechanism 2 includes multiple air volume adjusting plates 21 and multiple air direction adjusting components 22. The air volume adjusting plates 21 are tunably connected to the duct 1, and the multiple air volume adjusting plates 21 are arranged one-to-one with the multiple air supply hole groups. The air volume adjusting plates 21 have openings corresponding to the air outlets 11. The outlet 211 is of a matching size and is positioned directly opposite the air outlet 11. The air volume regulating plate 21 can be moved relative to the air duct 1 to cover the air outlet 11. Multiple air direction regulating components 22 are arranged one-to-one with multiple air outlet groups. The air direction regulating component 22 includes a mounting frame 221 and a guide vane 222 rotatably mounted on the mounting frame 221. The mounting frame 221 is connected to the air duct 1. The guide vane 222 is positioned on the side of the air volume regulating plate 21 away from the air outlet 11, facing the outlet 211. The guide vane 222 is used to guide the airflow direction.

[0030] In this embodiment, as Figure 1 and Figure 2 Figure 1 As shown ( Figure 1 The airflow adjustment component 22 is shown only at one of the air supply hole groups. Since the air duct 1 is used for air circulation, and multiple air supply hole groups are spaced apart along its length, each group including at least one air outlet 11, the air duct 1 can be connected to an air source to supply air to each test compartment in the aging test chamber. The airflow adjustment plate 21 has an outlet 211 matching the size of the air outlet 11. Since the outlet 211 is directly opposite the air outlet 11, under normal circumstances, the air in the air duct 1 can be blown out sequentially through the air outlet 11 and the outlet 211. Because the airflow adjustment plate 21 is adjustablely connected to the air duct 1, when the airflow adjustment plate 21 moves relative to the air duct 1, the outlet 211... By offsetting the air outlet 11, the airflow regulating plate 21 can partially cover the air outlet 11. Therefore, by moving the airflow regulating plate 21, the airflow rate from the air outlet 11 can be adjusted until the outlet 211 and the air outlet 11 are completely offset and do not overlap. At this point, the airflow regulating plate 21 completely blocks the air outlet 11, thus closing the air outlet 11 of this air supply group. The guide vane 222 of the airflow direction regulating component 22 is installed on the air duct 1 via the mounting bracket 221. Since the guide vane 222 is positioned directly opposite the outlet 211 and can rotate, the operator can rotate the guide vane 222 to change the airflow direction according to the test requirements. This gas delivery device has a simple structure, can independently supply air to each layer of space within the aging test chamber, and can adjust the airflow volume and direction of each air outlet 11 according to actual needs, thereby greatly improving the flexibility and practicality of the test.

[0031] like Figure 1 As shown, each air supply hole group includes multiple air supply ports 11; in this embodiment, the shape of the air supply ports 11 can be waist-shaped, circular or rectangular. The shape and number of air supply ports 11 in each air supply hole group are not limited. The multiple air supply ports 11 in each air supply hole group are evenly arranged to ensure that the airflow of the air supply hole group can be blown out stably and evenly.

[0032] The specific connection method and structure between the air volume regulating plate 21 and the air duct 1 can be set according to the actual situation. In this embodiment, for example... Figure 1 and Figure 2 As shown, the air volume regulating plate 21 has a waist-shaped hole 212. The bolts passing through the waist-shaped hole 212 fix the air volume regulating plate 21 and the air duct 1. The length direction of the waist-shaped hole 212 is the moving direction of the air volume regulating plate 21. When it is necessary to move the air volume regulating plate 21 to adjust the air volume, the operator loosens the bolts and then pushes the air volume regulating plate 21 along the length direction of the waist-shaped hole 212. The air volume regulating plate 21 will then cover part of the air outlet 11, thereby achieving the purpose of adjusting the air volume. After the air volume regulating plate 21 is moved to the designated position, the operator tightens the bolts.

[0033] The specific structure of the airflow adjustment component 22 can be set according to the actual situation, as long as it can change the direction of the airflow blown out of the outlet 211. In this embodiment, the airflow adjustment component 22 is a louvered air outlet commonly used in the art. Each airflow adjustment component 22 includes multiple parallel guide vanes 222, which are evenly connected to the mounting frame 221 at intervals. The mounting frame 221 has a rectangular frame structure, and the airflow adjustment plate 21 has a rectangular plate structure. The frame of the mounting frame 221 is fixedly connected to the airflow adjustment plate 21 by bolts. The guide vanes 222 have a long strip structure, and the two ends of the guide vanes 222 are rotatably connected to the mounting frame 221 along the length direction.

[0034] To further improve the ease of adjustment of the wind direction adjustment component 22, such as Figure 2 As shown, the wind direction adjustment component 22 also includes a linkage rod 223, which is connected in sequence to multiple guide vanes 222. The rotation of one guide vane 222 can drive the linkage rod 223 to move, thereby driving the other guide vanes 222 to rotate accordingly. In this embodiment, the wind direction adjustment component 22 is a louvered air outlet commonly used in the art. The linkage rod 223 is fixedly connected in sequence to each guide vane 222, and when the guide vane 222 rotates, the linkage rod 223 can translate in the same direction as the rotation of the guide vane 222. When any guide vane 222 rotates, the other guide vanes 222 will rotate synchronously under the drive of the linkage rod 223, thereby achieving linkage and greatly improving the convenience of adjustment.

[0035] In this embodiment, the wind direction adjustment component 22 also includes an adjustment motor, which is fixedly mounted on the mounting frame 221. The output end of the adjustment motor is connected to any of the guide vanes 222. One end of the mounting frame 221 is provided with an installation space for accommodating the adjustment motor. The operator can electrically control the rotation of the guide vanes 222 by adjusting the motor. It is understood that the rotation range of the guide vanes 222 is 180°. When rotating, they will guide the airflow to blow in different directions. When the guide vanes 222 rotate to be parallel to the outlet 211, all the guide vanes 222 on the same wind direction adjustment component 22 will form a flat plane to cover the outlet 211, thereby also cutting off the airflow and stopping the blowing of air.

[0036] like Figure 1 and Figure 2 As shown, the mounting bracket 221 is detachably mounted on the airflow regulating plate 21. Since the mounting bracket 221 is mounted on the airflow regulating plate 21, when the airflow regulating plate 21 moves, the mounting bracket 221 will also move synchronously, so that the guide vanes 222 of the airflow direction regulating component 22 can always be aligned with the outlet 211 of the airflow regulating plate 21, thereby ensuring that the airflow direction can always be accurately adjusted.

[0037] This embodiment also provides an aging test chamber, which includes a fan, a test chamber body, and the aforementioned gas delivery device. Air duct 1 is connected to the test chamber body, and each air outlet group is positioned directly opposite each layer of the test space within the test chamber body. The fan is used to blow airflow into air duct 1. In this embodiment, the fan, through the gas delivery device, can blow airflow into each independent space within the test chamber to meet the aging test requirements. Furthermore, this aging test chamber can individually adjust the airflow volume and direction for each independent space within the test chamber body, thereby meeting the requirements for comparative aging tests under different operating conditions, further improving the diversity and accuracy of the tests.

[0038] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
