Description

Technical Field

[0001] This invention relates to the field of temperature and humidity testing technology, and more specifically, to a rapid temperature and humidity testing device. Background Technology

[0002] A rapid temperature and humidity test chamber is a device used to simulate the performance of products under extreme temperature and humidity environments (especially drastic temperature changes combined with high humidity). It is widely used in electronics, automotive, aerospace, materials, and military industries to conduct environmental adaptability, reliability, and accelerated life testing of products.

[0003] Existing technologies, such as Chinese invention application CN117205974A, disclose a wide-range programmable damp heat alternating test chamber, which can realize the programmability of damp heat simulation and its coupled environment. By inputting the temperature and humidity values ​​of any curve model within the temperature and humidity range, and by predicting the structural model of the test product, the temperature and humidity coupled environment of the test product for a long time can be simulated in a short time. However, in actual use, the existing device is not convenient to achieve uniform heating, humidification and cooling of the test product during the test, which can easily affect the accuracy of the experiment.

[0004] To address the aforementioned issues, some solutions have been proposed in existing technologies. For example, Chinese invention patent CN119076068A discloses a programmable high and low temperature alternating humidity test chamber. In this device, multiple rotating seats rotate at the same speed during testing, ensuring that the product on the seats is uniformly heated, cooled, and humidified, thereby improving testing efficiency and accuracy. However, in practical use, a complex transmission structure is required to drive the rotation, resulting in high maintenance costs. Furthermore, while rotating the product can improve experimental accuracy and efficiency to some extent, high-speed rotation can easily cause the product to detach. To prevent this, existing technologies use airbags to clamp the product, which can affect the uniform heating, cooling, and humidification, further reducing testing efficiency and accuracy. Summary of the Invention

[0005] To address the problems existing in the prior art, the purpose of this invention is to provide a rapid temperature change and humidity testing device that can improve testing efficiency.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A rapid temperature change and humidity test device includes a test chamber, a placement plate slidably installed on the bottom wall of the test chamber, an annular plate rotatably installed on the bottom wall of the test chamber, an installation ring fixedly installed on the top wall of the annular plate, air rods uniformly fixedly installed on the top wall of the installation ring, and a linkage component provided on the annular plate.

[0008] The linkage component includes an annular groove formed on an annular plate, with impellers uniformly fixedly installed in the annular groove. A fan is fixedly installed on the side wall of the test chamber, and an air pipe that mates with the impeller is fixedly installed on the output end of the fan. A connecting pipe is fixedly installed on the test chamber. An air groove communicating with the connecting pipe is formed on the mounting ring, and the annular groove is connected to the air groove through the connecting pipe. A vertical groove communicating with the air groove is formed on the air rod, and air holes are uniformly formed on the vertical groove. A cover is detachably installed on the test chamber.

[0009] Furthermore, a horizontal groove is provided on the bottom wall of the test chamber, and a linkage block that is fixedly connected to the placement plate is slidably installed in the horizontal groove. A first spring is installed between the linkage block and the horizontal groove. A protrusion is fixedly installed on the placement plate, and the side wall of the protrusion away from the placement plate is inclined. A pusher is fixedly installed on the annular plate.

[0010] Furthermore, thin rods are uniformly fixedly installed on the top wall of the placement plate, and limiting rods that cooperate with the thin rods are uniformly provided on the top wall of the placement plate.

[0011] Furthermore, a groove is formed on the top wall of the placement plate, an installation block is slidably installed in the groove, an arc-shaped plate is fixedly installed on the top wall of the installation block, and the limiting rod is fixedly installed on the top wall of the arc-shaped plate.

[0012] Furthermore, a second spring is installed between the mounting block and the groove, a magnet is embedded in the mounting block, and an electromagnet electrically connected to the fan is embedded in the placement plate.

[0013] Furthermore, an observation port is provided on the side wall of the test chamber, and a glass plate is embedded in the observation port.

[0014] Furthermore, symmetrical sliding rods are installed on the side wall of the test chamber, a cleaning plate is slidably installed on the sliding rod, a sponge is installed on the cleaning plate, a third spring that cooperates with the sliding rod is installed between the cleaning plate and the test chamber, and a linkage rod that cooperates with the cleaning plate is fixedly installed on the air rod.

[0015] Furthermore, the inclined surface of the protrusion is a smooth mirror surface.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] (1) This scheme uses an impeller to blow the impeller to rotate as the airflow flows into the annular groove. During the rotation of the impeller, the annular plate is driven to rotate. Then, during the rotation of the annular plate, the air rod is driven to rotate through the mounting ring. At the same time, when the airflow passes through the connecting pipe, the airflow will flow into the air groove through the connecting pipe and then into the vertical groove through the air groove. Then, it will be blown onto the product to be tested through the air holes on the vertical groove. This can improve the uniform heating, cooling and humidification of the product to be tested, and improve the efficiency of the uniform heating, cooling and humidification of the product to be tested, thus improving the efficiency and accuracy of the test.

[0018] (2) This scheme uses the cooperation of the protrusion and the push block to drive the push block to rotate during the rotation of the annular plate. During the rotation of the push block, it gradually contacts the inclined surface of the protrusion and applies a pushing force to the inclined surface of the protrusion. Then, under the action of the pushing force, the protrusion drives the placement plate to move. During the movement of the placement plate, it drives the test item to move. During the movement of the placement plate, it drives the linkage block to squeeze the first spring. When the protrusion and the push block are separated, the first spring extends and drives the placement plate to reset. That is, during the rotation of the annular plate, the test item can be driven to swing back and forth, thereby improving the contact effect between the test item and the airflow and further improving the test efficiency.

[0019] (3) By setting a limiting rod, the position of the test product can be limited by the thin rod and the limiting rod when the placement plate shakes, thereby preventing the test product from falling off the placement plate. During the operation of the fan, the electromagnet is energized and generates a magnetic field. Then, under the action of the magnetic field, the magnet block drives the mounting block to move towards the electromagnet and squeeze the second spring. During the movement of the mounting block, the limiting rod moves through the arc plate. Then, during the movement of the limiting rod, it gradually comes into contact with the test product and drives the test product to contact the thin rod, thereby clamping and fixing the test product. This effectively avoids the test product from colliding with the thin rod during the shaking of the placement plate, which would damage the test product and the thin rod, affecting the test efficiency and the test accuracy. This further improves the test efficiency and test accuracy.

[0020] (4) This solution sets up a cleaning plate, which drives the linkage rod to rotate during the rotation of the air rod. During the rotation of the linkage rod, it gradually comes into contact with the cleaning plate and drives the cleaning plate to slide along the slide rod. At this time, the third spring is stretched. When the third spring reaches its maximum stretch, the linkage rod gradually disengages from the cleaning plate. At this time, the third spring contracts and drives the cleaning plate to reset. That is, during the rotation of the air rod, the cleaning plate can be driven to move back and forth. During the back and forth movement of the cleaning plate, the sponge can be driven to clean the water vapor on the glass slide, effectively avoiding the water vapor from affecting the normal observation of the test by the user and further improving the test efficiency.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1 to 8 A rapid temperature change and humidity test device includes a test chamber 1, a placement plate 2 slidably installed on the bottom wall of the test chamber 1, an annular plate 3 rotatably installed on the bottom wall of the test chamber 1, an installation ring 4 fixedly installed on the top wall of the annular plate 3, air rods 5 uniformly fixedly installed on the top wall of the installation ring 4, and a linkage component 6 provided on the annular plate 3.

[0037] The linkage component 6 includes an annular groove formed on the annular plate 3, in which impellers 601 are uniformly fixedly installed. A fan 602 is fixedly installed on the side wall of the test chamber 1. An air pipe 603 that mates with the impeller 601 is fixedly installed on the output end of the fan 602. A connecting pipe 604 is fixedly installed on the test chamber 1. An air groove communicating with the connecting pipe 604 is formed on the mounting ring 4, and the annular groove is connected to the air groove through the connecting pipe 604. A vertical groove communicating with the air groove is formed on the air rod 5, and air holes 605 are uniformly formed on the vertical groove. A cover 606 is detachably installed on the test chamber 1.

[0038] In use, the product to be tested is placed on the top wall of the placement plate 2, and then the cover 606 is fixed to the test chamber 1. When it is necessary to conduct heat, cold or humidity tests on the product, the tester can introduce the corresponding hot air, cold air or moisture into the air pipe 603 through the fan 602, and then flow into the annular groove through the air pipe 603. During the flow of air into the annular groove, the impeller 601 will rotate. During the rotation of the impeller 601, the annular plate 3 will rotate. During the rotation of the annular plate 3, the air rod 5 will rotate through the mounting ring 4. At the same time, when the airflow passes through the connecting pipe 604, the airflow will flow into the air groove through the connecting pipe 604, and then flow into the vertical groove through the air groove. Then, it will be blown onto the product to be tested through the air hole 605 on the vertical groove. In this way, while ensuring that the product to be tested is uniformly heated, cooled or humidified, the efficiency of uniform heating, cooling and humidification of the product is improved, which plays a role in improving the efficiency and accuracy of the test.

[0039] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a horizontal groove is provided on the bottom wall of the test chamber 1. A linkage block 701, which is fixedly connected to the placement plate 2, is slidably installed in the horizontal groove. A first spring 702 is installed between the linkage block 701 and the horizontal groove. A protrusion 703 is fixedly installed on the placement plate 2, and the side wall of the protrusion 703 away from the placement plate 2 is inclined. A pusher 704 is fixedly installed on the annular plate 3.

[0040] By adopting the above technical solution, the pusher 704 rotates during the rotation of the annular plate 3, and gradually contacts the inclined surface of the protrusion 703 and applies a pushing force to the inclined surface of the protrusion 703. Then, under the action of the pushing force, the protrusion 703 drives the placement plate 2 to move. During the movement of the placement plate 2, the test item moves. During the movement of the placement plate 2, the linkage block 701 squeezes the first spring 702. When the protrusion 703 and the pusher 704 disengage, the first spring 702 extends and drives the placement plate 2 to reset. That is, during the rotation of the annular plate 3, the test item can be driven to swing back and forth, thereby improving the contact effect between the test item and the airflow and further improving the test efficiency.

[0041] like Figure 2 , Figure 3 , Figure 6 As shown, thin rods 801 are uniformly fixedly installed on the top wall of the placement plate 2, and limiting rods 802 that cooperate with the thin rods 801 are uniformly provided on the top wall of the placement plate 2.

[0042] The top wall of the placement plate 2 is provided with a groove, and an installation block 803 is slidably installed in the groove. An arc plate 804 is fixedly installed on the top wall of the installation block 803, and the limiting rod 802 is fixedly installed on the top wall of the arc plate 804.

[0043] A second spring 805 is installed between the mounting block 803 and the groove. A magnet 806 is embedded in the mounting block 803. An electromagnet 807 electrically connected to the fan 602 is embedded in the placement plate 2.

[0044] By adopting the above technical solution, when the placement plate 2 causes the test product to shake, the position of the test product can be limited by setting the thin rod 801 and the limiting rod 802, thereby preventing the test product from falling off the placement plate 2 and affecting the test efficiency. During the operation of the fan 602, the electromagnet 807 is energized and generates a magnetic field. Under the action of the magnetic field, the magnet block 806 drives the mounting block 803 to move towards the electromagnet 807 and squeeze the second spring 805. During the movement of the mounting block 803, the limiting rod 802 is moved by the arc plate 804. Then, during the movement of the limiting rod 802, it gradually comes into contact with the test product and drives the test product to contact the thin rod 801, thereby clamping and fixing the test product. This effectively avoids the test product from colliding with the thin rod 801 during the shaking of the placement plate 2, which would damage the test product and the thin rod 801, affecting the test efficiency and accuracy, and further improving the test efficiency and accuracy.

[0045] Then, after the test is completed, as the fan (602) is powered off, the magnetic field of the electromagnet (807) disappears. At this time, the second spring (805) extends and drives the mounting block (803) to reset. During the reset process of the mounting block (803), the limit rod (802) is disengaged from the test product through the arc plate (804), thereby automatically releasing the fixation of the test product, making it easier for users to pick up and put down the test product, and further improving the test efficiency.

[0046] like Figure 2 , Figure 7 , Figure 8 As shown, an observation port is provided on the side wall of the test chamber 1, and a glass plate 901 is embedded in the observation port.

[0047] A sliding rod 902 is symmetrically installed on the side wall of the test chamber 1. A cleaning plate 903 is slidably installed on the sliding rod 902. A sponge 904 is installed on the cleaning plate 903. A third spring 906 that cooperates with the sliding rod 902 is installed between the cleaning plate 903 and the test chamber 1. A linkage rod 907 that cooperates with the cleaning plate 903 is fixedly installed on the air rod 5.

[0048] By adopting the above technical solution, during the experiment, the test personnel can observe the test situation through the glass slide 901, which facilitates the user in determining the test progress and effectively improves the test efficiency. When moisture enters the test chamber 1, some moisture will adhere to the surface of the glass slide 901. Then, during the rotation of the air rod 5, it will drive the linkage rod 907 to rotate. As the linkage rod 907 rotates, it will gradually come into contact with the cleaning plate 903 and drive the cleaning plate 903 to slide along the slide rod 902. At this time, the third spring 906 will be stretched. When the third spring 906 reaches its maximum stretch, the linkage rod 907 will gradually disengage from the cleaning plate 903. At this time, the third spring 906 will contract and drive the cleaning plate 903 to reset. That is, during the rotation of the air rod 5, the cleaning plate 903 can be moved back and forth. During the back and forth movement of the cleaning plate 903, the sponge 904 can be driven to clean the moisture on the glass slide 901, effectively avoiding the moisture from affecting the user's normal observation of the test situation and further improving the test efficiency.

[0049] like Figure 3 As shown, the inclined surface of the protrusion 703 is a smooth mirror surface.

[0050] By adopting the above technical solution, during the process of the linkage block 701 driving the placement plate 2 to move through the protrusion 703, by making the surface of the protrusion 703 a smooth mirror, the friction between the protrusion 703 and the linkage block 701 can be reduced, thereby extending the service life of the protrusion 703 and the linkage block 701.

[0051] Instructions for use: When using, place the product to be tested on the top wall of the placement plate 2, and then fix the cover 606 on the test chamber 1. When it is necessary to conduct heat, cold or humidity tests on the product, the tester can introduce the corresponding hot air, cold air or moisture into the air pipe 603 through the fan 602, and then flow into the annular groove through the air pipe 603. During the process of the airflow flowing into the annular groove, it will blow the impeller 601 to rotate. During the rotation of the impeller 601, it will drive the annular plate 3 to rotate. Then, during the rotation of the annular plate 3, it will drive the air rod 5 to rotate through the mounting ring 4. At the same time, when the airflow passes through the connecting pipe 604, the airflow will flow into the air groove through the connecting pipe 604, and then flow into the vertical groove through the air groove. Then, it will blow onto the product to be tested through the air hole 605 on the vertical groove, thereby ensuring that the product to be tested is uniformly heated, cooled and humidified.

[0052] Then, during the rotation of the annular plate 3, the push block 704 is driven to rotate. During the rotation of the push block 704, it gradually comes into contact with the inclined surface of the protrusion 703 and applies a pushing force to the inclined surface of the protrusion 703. Under the action of the pushing force, the protrusion 703 drives the placement plate 2 to move. During the movement of the placement plate 2, the test item is moved. During the movement of the placement plate 2, the linkage block 701 is driven to squeeze the first spring 702. When the protrusion 703 and the push block 704 are disengaged, the first spring 702 extends and drives the placement plate 2 to reset. That is, during the rotation of the annular plate 3, the test item can be driven to swing back and forth.

[0053] Furthermore, when the placement plate 2 causes the test product to shake, the position of the test product can be limited by setting the thin rod 801 and the limiting rod 802. During the operation of the fan 602, the electromagnet 807 is energized and generates a magnetic field. Then, under the action of the magnetic field, the magnet block 806 drives the mounting block 803 to move towards the electromagnet 807 and squeeze the second spring 805. During the movement of the mounting block 803, the limiting rod 802 is moved by the arc plate 804. Then, during the movement of the limiting rod 802, it gradually comes into contact with the test product and drives the test product to contact the thin rod 801, thereby clamping and fixing the test product.

[0054] Finally, as the air spring 5 rotates, it drives the linkage rod 907 to rotate. As the linkage rod 907 rotates, it gradually comes into contact with the cleaning plate 903 and drives the cleaning plate 903 to slide along the slide rod 902. At this time, the third spring 906 is stretched. When the third spring 906 reaches its maximum stretch, the linkage rod 907 gradually disengages from the cleaning plate 903. At this time, the third spring 906 contracts and drives the cleaning plate 903 to reset. That is, as the air spring 5 rotates, it can drive the cleaning plate 903 to move back and forth. Then, as the cleaning plate 903 moves back and forth, it can drive the sponge 904 to clean the water vapor on the glass plate 901.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
