Description

Technical Field

[0001] This utility model relates to the field of aging cabinet technology, and in particular to a high-temperature aging cabinet capable of switching air ducts. Background Technology

[0002] Aging test chambers are a general term for products in the environmental testing industry. They encompass various aging test methods, including ozone aging, ultraviolet aging, xenon lamp aging, ventilation-type thermal aging, high-temperature aging, and salt spray corrosion aging. It is one of the most important artificial environmental climate testing methods. Aging test chambers are used to test wires, cables, insulation, or coated rubber samples to compare the tensile strength and elongation of the samples before and after aging.

[0003] The technology used by high-temperature aging cabinets on the market to maintain a constant temperature mainly relies on the exhaust of hot air inside for internal heat dissipation, ensuring that the internal temperature does not accumulate excessively. The high-temperature aging cabinet with patent number CN217543270U uses the exhaust vent at the top to dissipate excess heat inside. However, its exhaust vent has a single function, only used for airflow discharge, and cannot control the internal airflow circulation. Its internal airflow circulation is achieved by setting up multiple sets of air channels, which is complex and cumbersome, and not conducive to reducing production costs.

[0004] Therefore, it is necessary to propose a high-temperature aging cabinet that can switch air ducts to improve the functionality of the internal components of the machine, so as to take into account both exhaust and internal air circulation functions in a switching manner. Utility Model Content

[0005] To address the aforementioned issues, this invention proposes a high-temperature aging cabinet capable of switching air ducts to enhance the functionality of internal machine components, thereby balancing exhaust and internal airflow circulation through a switching mechanism.

[0006] This utility model is achieved through the following technical solution: This utility model proposes a high-temperature aging cabinet capable of switching air ducts, including a cabinet body, a blower mechanism, a heating component, a first air duct switching mechanism, and a second air duct switching mechanism. The blower mechanism, the heating component, the first air duct switching mechanism, and the second air duct switching mechanism are all fixedly connected to one end of the cabinet body. An aging chamber is provided inside the cabinet body. The air inlet of the blower mechanism faces the aging chamber. The heating component is located on both sides of the blower mechanism and is connected to the air outlets on both sides of the blower mechanism. The first air duct switching mechanism is located on one side of the heating component and is connected to the heating component. The second air duct switching mechanism is located on the other side of the heating component and is connected to the heating component. The blower mechanism, the heating component, the first air duct switching mechanism, and the second air duct switching mechanism are all electrically connected to the cabinet body. The first air duct switching mechanism and the second air duct switching mechanism can switch the air ducts to allow the hot air generated by the blower mechanism after passing through the heating component to circulate within the aging chamber, or to allow the hot air generated by the blower mechanism after passing through the heating component to be blown out to the outside, thereby regulating the temperature within the aging chamber.

[0007] Furthermore, the first air duct switching mechanism includes an air guide box, a driving device, and an air guide deflector. The driving device is electrically connected to the cabinet. One end of the air guide box is connected and connected to one side of the heating component. The driving device is fixedly connected to one side of the air guide box. The rotating shaft of the driving device extends into the air guide box and is fixedly connected to one end of the air guide deflector. The driving device drives the air guide deflector to rotate at a preset angle, which can cause air to be blown into the aging chamber or blown out of the air guide box. The first air duct switching mechanism has the same structure as the second air duct switching mechanism.

[0008] Furthermore, the air guide box is provided with a first air outlet plate and a second air outlet plate, the first air outlet plate and the second air outlet plate are set at an angle, the air guide baffle is located between the first air outlet plate and the second air outlet plate, the first air outlet plate is connected to the outside, and the second air outlet plate is connected to the aging chamber.

[0009] Furthermore, an air inlet channel is provided between the first air outlet panel and the second air outlet panel, and the air inlet channel is connected to the heating component.

[0010] Furthermore, one end of the air guide box is provided with an air outlet duct, and one side of the first air outlet panel is provided with an air outlet space, and the air outlet duct is connected to the air outlet space.

[0011] Furthermore, the two side walls of the aging chamber are respectively provided with a first drainage channel and a second drainage channel. The first drainage channel is connected to the air guide box of the first air duct switching mechanism, and the second drainage channel is connected to the air guide box of the second air duct switching mechanism. A portion of the first drainage channel and a portion of the second drainage channel are connected to the aging chamber.

[0012] Furthermore, the bottom wall of the aging chamber is provided with a third drainage channel, the two ends of which are respectively connected to the first drainage channel and the second drainage channel, and one side of the third drainage channel is connected to the aging chamber.

[0013] Furthermore, the blower mechanism includes two blowers, which are symmetrically arranged. The air inlets of both blowers are connected to the aging chamber, and the air outlets of both blowers are arranged to face left and right and are respectively connected to the heating component. Both blowers are electrically connected to the cabinet.

[0014] Furthermore, the heating assembly includes two heating chambers, which are located at the air outlets of the two blowers and connected to the air outlets of the blowers. One heating chamber is connected to the first air duct switching mechanism, and the other heating chamber is connected to the second air duct switching mechanism. Both heating chambers are electrically connected to the cabinet.

[0015] Furthermore, the heating box assembly includes a connecting box and multiple heating rods. One end of the connecting box is fixedly connected and conductive to the air outlet of the blower, and the other end of the connecting box is connected and conductive to the first air duct switching mechanism or the second air duct switching mechanism. The multiple heating rods are arranged in an array and fixedly connected inside the connecting box, and all of the multiple heating rods are electrically connected to the cabinet.

[0016] The beneficial effects of this utility model are: This invention employs a first air duct switching mechanism and a second air duct switching mechanism to switch the air ducts inside the cabinet. This switches the air ducts so that the hot air generated after the blower passes through the heating component circulates within the aging chamber, maintaining the temperature within the aging chamber within a preset temperature range. If the temperature within the aging chamber exceeds the preset temperature range, the first and second air duct switching mechanisms can also switch to expelling the hot air generated after the blower passes through the heating component to the outside. This reduces the internal circulation of hot air, lowers the temperature within the aging chamber, and thus regulates the temperature within the aging chamber to maintain it within the preset temperature range, facilitating aging tests. In summary, this high-temperature aging cabinet with switchable air ducts improves the functionality of the internal components by switching between exhaust and internal air circulation.

[0019] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0020] Please refer to Figures 1-3 This utility model proposes a high-temperature aging cabinet capable of switching air ducts, including a cabinet body 1, a blower mechanism 2, a heating component 3, a first air duct switching mechanism 4, and a second air duct switching mechanism 5. The blower mechanism 2, heating component 3, first air duct switching mechanism 4, and second air duct switching mechanism 5 are all fixedly connected to one end of the cabinet body 1. An aging chamber 11 is provided inside the cabinet body 1. The air inlet 201 of the blower mechanism 2 faces the aging chamber 11. The heating component 3 is located on both sides of the blower mechanism 2 and is connected to the air outlets 202 on both sides of the blower mechanism 2. The first air duct switching mechanism 4 is located on the heating component... The first air duct switching mechanism 4 and the second air duct switching mechanism 5 are located on one side of the heating component 3 and connected to the heating component 3. The blower mechanism 2, the heating component 3, the first air duct switching mechanism 4, and the second air duct switching mechanism 5 are all electrically connected to the cabinet 1. The first air duct switching mechanism 4 and the second air duct switching mechanism 5 can switch the air duct so that the hot air formed after the blower mechanism 2 blows through the heating component 3 can circulate in the aging chamber 11, or so that the hot air formed after the blower mechanism 2 blows through the heating component 3 can be blown out to the outside, so as to regulate the temperature in the aging chamber 11.

[0021] In this embodiment, the first air duct switching mechanism 4 and the second air duct switching mechanism 5 are used to switch the air ducts inside the cabinet 1. When the aging chamber 11 urgently needs to be heated, the mechanism switches to allow the hot air formed by the blower mechanism 2 blowing through the heating component 3 to circulate in the aging chamber 11, so that the hot air is continuously blown and heated in the aging chamber 11, and the temperature in the aging chamber 11 is maintained within the preset temperature range. If the temperature in the aging chamber 11 is higher than the preset temperature range, the first air duct switching mechanism 4 and the second air duct switching mechanism 5 can also switch to allow the hot air formed by the blower mechanism 2 blowing through the heating component 3 to be blown out to the outside, thereby reducing the internal circulation of hot air and lowering the temperature in the aging chamber 11, thereby adjusting the temperature in the aging chamber 11 to be maintained within the preset temperature range, which is convenient for aging tests. There are two modes for cooling the aging chamber 11. The first mode is when the first air duct switching mechanism 4 and the second air duct switching mechanism 5 are switched, one of them switches to external air supply while the other continues to supply air internally. For example, the first air duct switching mechanism 4 is switched to external air supply while the second air duct switching mechanism 5 continues to supply air internally. At this time, the aging chamber 11 is cooling down, but the cooling speed is relatively slow, which is conducive to small-scale temperature control. The second mode is when the first air duct switching mechanism 4 and the second air duct switching mechanism 5 are switched to external air supply at the same time. At this time, the aging chamber 11 is cooling down rapidly, which is conducive to large-scale temperature control. In summary, the high-temperature aging cabinet, which can switch air ducts, can improve the functionality of the internal components of the machine, and can balance the functions of exhaust and internal air circulation by switching between them.

[0022] In this embodiment, the first air duct switching mechanism 4 includes an air guide box 41, a drive device 42, and an air guide deflector 43. The drive device 42 is electrically connected to the cabinet 1 and is a stepper motor, which is easy to program and rotate at a preset angle. One end of the air guide box 41 is connected and conductive to one side of the heating component 3. The drive device 42 is fixedly connected to one side of the air guide box 41. The rotating shaft 421 of the drive device 42 extends into the air guide box 41 and is fixedly connected to one end of the air guide deflector 43. The drive device 42 drives the air guide deflector 43 to rotate at a preset angle, which can cause air to blow into the aging chamber 11 or blow out of the air guide box 41. When it is necessary to change the air duct, the drive device 42 rotates at a preset angle, so that... The air guide plate 43 rotates at a preset angle to guide the air to a preset area. For example, when the aging chamber 11 needs to be cooled, taking the original angle between the air guide plate 43 and the horizontal line as 35 degrees, the inclined surface of the air guide plate 43 is facing upward, which means that the air will be guided upward. After the drive device 42 rotates downward by 70 degrees, it drives the air guide plate 43 to rotate downward by 70 degrees, so that the inclined surface of the air guide plate 43 is facing downward, which means that the air will be guided downward and blown into the aging chamber 11. The first air duct switching mechanism 4 and the second air duct switching mechanism 5 have the same structure, so that the first air duct switching mechanism 4 and the second air duct switching mechanism 5 are operated in the same way, which is convenient for programming control.

[0023] In this embodiment, the air guide box 41 is provided with a first air outlet plate 411 and a second air outlet plate 412, which are arranged at an angle. A guide vane 43 is located between the first air outlet plate 411 and the second air outlet plate 412. The first air outlet plate 411 is connected to the outside, and the second air outlet plate 412 is connected to the aging chamber 11. When the guide vane 43 is rotated at a preset angle, the first air outlet plate 411 or the second air outlet plate 412 provides support for the guide vane 43, ensuring sufficient support to resist the blowing force of the wind and guide the air into the preset area. The first air outlet plate 411... 1. A first through groove 4112 is provided, and a second through groove 4121 is provided on the second air outlet plate 412. The second through groove 4121 is connected to the aging chamber 11. When the air guide plate 43 is flipped upward and attached to the first air outlet plate 411, the air guide plate 43 blocks the first through groove 4112. At this time, the air will enter the aging chamber 11 from the second through groove 4121 and then be drawn out of the aging chamber 11 again through the air inlet 201 of the blower mechanism 2 to form an internal circulation blowing. When the air guide plate 43 is flipped downward and attached to the second air outlet plate 412, the air guide plate 43 blocks the second through groove 4121. At this time, the air will be blown out to the outside from the first through groove 4112.

[0024] In this embodiment, an air inlet channel 413 is provided between the first air outlet plate 411 and the second air outlet plate 412. The air inlet channel 413 is connected to the heating component 3. The air inlet channel 413 provides a space for the rotation of the air guide plate 43. After the air is heated by the heating component 3, it first enters the air inlet channel 413, and then enters the aging chamber 11 or is blown out to the outside under the guidance of the angle of the air guide plate 43.

[0025] In this embodiment, one end of the air guide box 41 is provided with an air outlet duct 414, and one side of the first air outlet panel 411 is provided with an air outlet space 4111. The air outlet duct 414 is connected to the air outlet space 4111. The air outlet duct 414 can be connected to a flexible hose to guide and blow out the air. After the air is blown out from the first through groove 4112 of the first air outlet panel 411, the air outlet space 4111 can constrain the turbulent airflow and then blow it out to the outside through the air outlet duct 414.

[0026] In this embodiment, the two side walls of the aging chamber 11 are respectively provided with a first drainage channel 111 and a second drainage channel 112. The first drainage channel 111 is connected to the air guide box 41 of the first air duct switching mechanism 4, and the second drainage channel 112 is connected to the air guide box 41 of the second air duct switching mechanism 5. A portion of the first drainage channel 111 and a portion of the second drainage channel 112 are connected to the aging chamber 11. When air is blown into the aging chamber 11, a portion of the air will blow over the equipment being tested. Another part of the air will flow along the first drainage channel 111 and the second drainage channel 112. Finally, the two streams of air will converge from the middle area of ​​the aging chamber 11 and blow upward. Meanwhile, the air inlet 201 of the blower mechanism 2 is constantly drawing in air. At this time, the upward-blown air will be drawn into the air inlet 201, forming an internal circulation. Multiple first through holes are provided on one side of the first drainage channel 111 and the second drainage channel 112. The flowing air can flow into the aging chamber 11 through the multiple first through holes.

[0027] In this embodiment, the bottom wall of the aging chamber 11 is provided with a third drainage channel 113. The two ends of the third drainage channel 113 are respectively connected to the first drainage channel 111 and the second drainage channel 112, and the side of the third drainage channel 113 is connected to the aging chamber 11. The third drainage channel 113 is set at the bottom of the aging chamber 11 to facilitate the drainage and collection of the air blown in from the first drainage channel 111 and the second drainage channel 112. The top of the third drainage channel 113 is provided with a plurality of second through holes, and the collected air can flow upward through the plurality of second through holes.

[0028] In this embodiment, the blower mechanism 2 includes two blowers 21, which are symmetrically arranged. The air inlets 201 of both blowers 21 are connected to the aging chamber 11, and the air outlets 202 of both blowers 21 are arranged facing left and right and are connected to the heating component 3 respectively. Both blowers 21 are electrically connected to the cabinet 1. Using two blowers 21, air can be delivered to the left and right sides at the same time. Finally, the airflow flows from both sides in the aging chamber 11, converges in the middle area, and is then drawn back in to be delivered from both sides, which is conducive to forming an internal airflow circulation.

[0029] In this embodiment, the heating assembly 3 includes two heating chamber groups 31. The two heating chamber groups 31 are located at the air outlets 202 of the two blowers 21 and are connected to the air outlets 202 of the blowers 21. One heating chamber group 31 is connected to the first air duct switching mechanism 4, and the other heating chamber group 31 is connected to the second air duct switching mechanism 5. Both heating chamber groups 31 are electrically connected to the cabinet 1. The two heating chamber groups 31 can meet the hot air blowing of the two blowers 21. The number of heating chamber groups 31 also depends on the number of blowers 21. The blowing mechanism 2 can also be composed of multiple blowers 21. When the blowers 21 blow air, the heating chamber groups 31 heat up to the preset temperature. After the air blows, the airflow can obtain a temperature close to the preset temperature. After multiple cycles of blowing, the airflow inside the aging chamber 11 is the same as the preset temperature.

[0030] In this embodiment, the heating box assembly 31 includes a connecting box 311 and multiple heating rods 312. One end of the connecting box 311 is fixedly connected to and in communication with the air outlet 202 of the blower 21, and the other end of the connecting box 311 is connected to and in communication with the first air duct switching mechanism 4 or the second air duct switching mechanism 5. The multiple heating rods 312 are arranged in an array and fixedly connected in the connecting box 311. All of the multiple heating rods 312 are electrically connected to the cabinet 1. The heating box assembly 31 also includes an airflow temperature sensor, which is used to detect the airflow temperature after it passes through the multiple heating rods 312. The array arrangement of the multiple heating rods 312 is conducive to the uniform heat absorption of the airflow when it passes through. After the airflow passes through the multiple heating rods 312, the airflow carries the temperature and is circulated.

[0031] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
