Description

Technical Field

[0001] This utility model relates to the field of test chamber technology, and in particular to a test chamber. Background Technology

[0002] A test chamber is a device used to test the function and performance of materials under various environmental conditions, such as high temperature, low temperature, and high humidity. During the use of the test chamber, the ventilation openings allow air exchange between the interior and other spaces, effectively regulating humidity and temperature within the chamber. The filters installed on the ventilation openings effectively block dust and impurities, preventing them from entering the chamber and ensuring the accuracy and reliability of the test results. However, long-term operation inevitably leads to the accumulation of dust and impurities in the filters, which can affect their filtration efficiency and permeability, and may even negatively impact the test results. Therefore, maintaining the cleanliness of the filters is crucial.

[0003] In related technologies, it is usually necessary to remove the filter screen from the test chamber and then thoroughly clean it. The cleaning process of the filter screen is cumbersome, time-consuming, and inefficient. Moreover, the repeated removal and installation of the filter screen can easily cause it to loosen, thereby reducing the filtering effect of the filter screen. Therefore, the cleaning method of the filter screen needs to be optimized. Utility Model Content

[0025] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0027] Hereinafter, with reference to the accompanying drawings, a test chamber 1000 according to a first aspect embodiment of the present invention will be described.

[0028] like Figure 1 , Figure 2 and Figure 4As shown, the test chamber 1000 includes a chamber body 100, which has a test chamber 120 and an equipment chamber 140. The test chamber 120 is used to hold the material to be tested, and the equipment chamber 140 is used to house a device for regulating the internal environment of the test chamber 120. At least one of the test chamber 120 and the equipment chamber 140 has a vent 160. The vent 160 can enable air exchange between the interior of the test chamber 120 and the equipment chamber 140 and other spatial environments. For example, the vent 160 on the test chamber 120 can be used to blow airflow to regulate the temperature into the test chamber 120, and the vent 160 on the equipment chamber 140 can connect the interior of the equipment chamber 140 with the external environment, but is not limited thereto.

[0029] The test chamber 1000 also includes a filter screen 200, a brush assembly 300, and a dust collection assembly 400. The filter screen 200 is located at the vent 160 and is situated outside the chamber 100. This reduces the amount of impurities and dust entering at least one of the test chamber 120 and the equipment chamber 140, thereby ensuring the reliable operation of the test chamber 1000. For example, the filter screen 200 located outside the vent 160 on the test chamber 120 reduces the amount of dust entering the test chamber 120, facilitating reliable testing. Similarly, the filter screen 200 located outside the vent 160 on the equipment chamber 140 reduces the amount of dust entering the equipment chamber 140, facilitating maintenance within the equipment chamber 140 and minimizing the impact of dust on heat dissipation of the devices within the equipment chamber 140. The brush assembly 300 is movably disposed in the housing 100 and is used to clean the filter screen 200. For example, the brush assembly 300 can be disposed on the side of the filter screen 200 away from the vent 160 (which can be understood as the brush assembly 300 being disposed on the outside of the filter screen 200). The brush assembly 300 includes a brush 320 and a brush head 340. A cavity 360 is defined inside the brush head 340. A first opening 362 communicating with the cavity 360 is formed on the cavity wall of the cavity 360. The brush 320 is disposed on the cavity wall of the cavity 360 and the brush 320 and the first opening 362 are located on the same side of the cavity 360. The vacuuming assembly 400 is disposed in the equipment cavity 140. The vacuuming port 420 of the vacuuming assembly 400 is connected to the cavity 360 through a connecting pipe 440.

[0030] It is understood that either the test chamber 120 or the equipment chamber 140 has a vent 160, or both the test chamber 120 and the equipment chamber 140 have vents 160.

[0031] As can be seen, the brush assembly 300 cleans the filter 200 by moving relative to the housing 100 and the filter 200. The brush 320 can clean dust and other debris from the filter 200. Since the suction port 420 of the vacuum assembly 400 is connected to the cavity 360 via the connecting pipe 440, and the brush 320 and the first opening 362 are located on the same side of the cavity 360, a negative pressure is generated at the suction port 420 when the vacuum assembly 400 is working. This negative pressure, generated inside the cavity 360 via the connecting pipe 440, allows the first opening 362 to draw in debris generated during the cleaning process by the brush 320. The dust and impurities separated on the filter 200 are removed, thus cleaning the filter 200. Furthermore, the dust and impurities separated on the filter 200 are less likely to fall to other locations, preventing contamination of other parts of the test chamber 1000. For example, when cleaning the filter 200 is required, the brush assembly 300 moves to clean it. The dust and impurities generated during cleaning are sucked away by the suction assembly 400 through the first opening 362 on the cavity 360, thereby cleaning the filter 200. This simplifies the cleaning process and improves cleaning efficiency.

[0032] Compared to some technologies where cleaning the filter screen usually requires removing it from the equipment and then cleaning it, which is a cumbersome and inefficient process, and the repeated removal and installation of the filter screen can easily cause it to loosen, the test chamber 1000 according to this utility model uses the movement of the brush assembly 300 to clean the filter screen 200. The dust and impurities generated during cleaning are sucked away by the dust suction assembly 400 through the first port 362 on the cavity 360, thereby improving the convenience and efficiency of cleaning the filter screen 200. The cleaning is quick and easy, and it solves the problem of the filter screen 200 becoming clogged due to long-term use. This facilitates the improvement of the cleanliness of the environment in which the test material is located in the test chamber 120, and / or the cleanliness of the environment in which the corresponding device is located in the equipment cavity 140. Moreover, the dust and other debris cleaned off the filter screen 200 are less likely to fall to other parts of the test chamber 1000 and cause contamination.

[0033] Obviously, the test chamber 1000 of this application embodiment can not only save cleaning time and improve cleaning efficiency, but also eliminate the need to disassemble the filter screen 200 for cleaning, thus improving the problem that the filter screen 200 is prone to loosening due to repeated disassembly and assembly.

[0034] like Figure 1 and Figure 5As shown, the operation display panel 750 is located on the front of the chamber 100, that is, the side of the test chamber 1000 facing the user, which facilitates the user to monitor and adjust the test parameters inside the test chamber 1000. The brush assembly 300 and the filter screen 200 are both located on the back of the chamber 100. Therefore, the operation display panel 750 and the brush assembly 300 and the filter screen 200 are respectively arranged on both sides of the chamber 100. Figure 1 To better illustrate the position and structure of the brush assembly 300 and the filter screen 200, the back cover of the housing 100 is not shown. This allows for a more direct view of the structure and position of the brush assembly 300 and the filter screen 200. Figure 1 The door of the equipment cavity 140 is not shown to facilitate a clear view of the structure inside the equipment cavity 140. In other words, the filter screen 200, brush assembly 300, and drive assembly 600 are all located on the rear side of the housing 100, or, to put it another way, the filter screen 200, brush assembly 300, and drive assembly 600 are all located on the outside of the housing 100. For ease of understanding, in... Figure 1 The filter 200, brush assembly 300, and drive assembly 600 are displayed.

[0035] like Figure 1 As shown, in some embodiments, the vent 160 is formed on the periphery of the chamber 100. For example, the vent 160 can be formed on any side of the front, rear, left, and right of the chamber 100, which can make the airflow smoother and improve the problem of airflow obstruction caused by improper placement of the vent 160. For example, if the vent 160 of the test chamber 120 is set on the periphery of the chamber 100, it helps to quickly adjust the environmental parameters such as temperature inside the test chamber 1000, and improve the stability and accuracy of the test environment adjustment. At the same time, by setting the vent 160 on the periphery of the chamber 100, the size and position of the vent 160 can be flexibly adjusted according to the test requirements to meet the ventilation requirements of different tests. When it is necessary to replace the filter 200, it is easier to approach the vent 160 for operation.

[0036] The brush assembly 300 is vertically and vertically positioned at the vent 160, which simplifies the movement of the brush assembly 300. This allows the user or the drive assembly 600 (described later) to more easily complete the cleaning of the filter 200, simplifying the operation process and improving cleaning efficiency. Furthermore, the cleaning range of the brush assembly 300 can be quickly determined during the design process, facilitating the rapid setting of a matching and appropriate brush assembly 300 based on the vent 160.

[0037] like Figure 1 , Figure 2 and Figure 4As shown, in some embodiments, the test chamber 1000 further includes a dust collection box 500, at least a portion of which is located below the brush 320. The dust collection box 500 is detachably connected to the brush head 340. It is evident that when the brush assembly 300 cleans the filter 200, most of the dust, impurities, and other contaminants brushed off are sucked away by the suction assembly 400. Most of the remaining contaminants fall into the dust collection box 500. For example, large clumps of dust brushed off by the brush assembly 300 can fall directly into the dust collection box 500 due to gravity, reducing the amount of contaminants re-emitted into the environment. Dust and other contaminants cleaned from the filter 200 are less likely to fall to other parts of the test chamber 1000 and cause pollution, thus improving the cleanliness of the exterior of the test chamber 1000. Because the dust collection box 500 is detachably connected to the brush head 340, users can easily disassemble the dust collection box 500 for cleaning or replacement, simplifying the cleaning process and reducing maintenance difficulty and costs. Meanwhile, the detachable dust collection box 500 also makes it easy for users to check the amount of dust accumulated inside, so as to clean it in time and improve the operational reliability of the impact test chamber 1000.

[0038] It is understood that the dust collection box 500 moves with the brush assembly 300 to collect dust and other debris that falls during cleaning. For example, the dust collection box 500 can be formed as a disc-shaped structure, with at least a portion of the dust collection box 500 located under the brush 320 to collect at least most of the falling dust; or, for example, the dust collection box 500 can be formed as a cover structure, covering the brush assembly 300 to collect more dust.

[0039] Of course, in other embodiments of this application, the test chamber 1000 may not include the dust collection box 500, in which case the dust collection component 400 can be configured to have appropriate suction power.

[0040] like Figure 1As shown, in some embodiments, the test chamber 1000 further includes a drive assembly 600, which drives the brush assembly 300 to reciprocate. The drive assembly 600 can control the moving speed of the brush 320, so as to more effectively remove impurities and dust from the filter screen 200. The drive assembly 600 includes a motor 610, a threaded rod 620, and a limiting rod 640. The motor 610 is connected to the threaded rod 620 to drive the threaded rod 620 to rotate around the central axis of the threaded rod 620. The threaded rod 620 and the limiting rod 640 are arranged in parallel and are respectively located on opposite sides of the vent 160. The threaded rod 620 is threadedly engaged with the brush head 340, and the limiting rod 640 is slidably engaged with the brush head 340 along the moving direction of the brush assembly 300. As can be seen, the two ends of the brush assembly 300 are connected to the threaded rod 620 and the limiting rod 640 respectively. The motor 610 controls the rotation of the threaded rod 620 to drive the brush assembly 300 to reciprocate, which helps the brush assembly 300 to clean the filter screen 200. This ensures that the internal environment of the test chamber 1000 is not affected by external factors. When the ventilation port 160 is located in the test chamber 120, it can improve the accuracy and reliability of the test results.

[0041] The limiting rod 640 and the brush head 340 slide and cooperate along the moving direction of the brush assembly 300. The limiting rod 640 restricts the brush head 340 from rotating with the threaded rod 620 and plays a certain guiding role in the movement of the brush head 340.

[0042] For example, the brush assembly 300 is vertically and vertically disposed at the vent 160, and the drive assembly 600 is used to drive the brush assembly 300 to reciprocate up and down. The threaded rod 620 and the limiting rod 640 are respectively disposed on opposite sides of the vent 160 in the horizontal direction, for example, the threaded rod 620 and the limiting rod 640 are symmetrically disposed on the left and right sides of the vent 160.

[0043] Optionally, the motor 610 is a reversible motor so as to realize the forward and reverse rotation of the threaded rod 620, thereby realizing the lifting and lowering of the brush assembly 300.

[0044] like Figure 1 , Figure 2 and Figure 4As shown, in some embodiments, the brush head 340 is formed as a cylindrical structure closed at one end. There are multiple first ports 362, and the multiple first ports 362 are spaced apart along the axial direction of the brush head 340. The connecting tube 440 extends into the cavity 360, and multiple second ports 442 are formed on the portion of the connecting tube 440 that extends into the cavity 360. Each second port 442 is opposite to a first port 362. Therefore, the connecting tube 440 and the brush head 340 are reliably matched, which facilitates the formation of a reliable dust collection structure. When the dust collection assembly 400 is started, the suction force generated by the suction port 420 can quickly pass through the connecting tube 440, the second port 442 and the first port 362 to suck the dust and impurities generated during the cleaning of the brush assembly 300 into the dust collection assembly 400. Thus, the dust collection assembly 400 can easily form a large suction range at the position of the filter screen 200 through the brush head 340, which helps to reduce the amount of dirt falling to other positions, improves dust collection efficiency, and keeps the filter screen 200 clean.

[0045] The connecting pipe 440 extends into the cavity 360, and the increased mating length between the connecting pipe 440 and the cavity 360 makes the connection between the connecting pipe 440 and the cavity 360 more secure and stable. This helps to prevent the connection from loosening or falling off due to vibration or impact during use, effectively reducing the possibility of failure and thus improving the reliability of the test chamber 1000.

[0046] like Figure 1 and Figure 5 As shown, in some embodiments, the vacuum assembly 400 has a pull-out dust collection box 460. One side wall of the housing 100 corresponding to the dust collection box 460 has an opening opposite to the dust collection box 460. A switch door 180 is provided at the opening for opening and closing. The pull-out dust collection box 460 allows users to easily remove the dust-filled box 460 from the vacuum assembly 400 for cleaning or replacement, simplifying the cleaning process and improving maintenance efficiency. The opposite orientation of the opening and the dust collection box 460, along with the switch door 180, allows users to easily pull out the dust collection box 460 without disassembling the entire vacuum assembly 400, reducing operational difficulty. Furthermore, the design of the opening and the dust collection box 460 allows the dust collection box 460 of the vacuum assembly 400 to be housed within the housing 100, without occupying additional space, making the overall structure of the test chamber 1000 more compact and aesthetically pleasing.

[0047] For example, when using the brush assembly 300 to clean the filter screen 200, first start the motor 610. The rotation of the motor 610 drives the threaded rod 620 to rotate, thereby driving the brush assembly 300 to move up and down along the limit rod 640. At the same time, start the vacuum assembly 400. The brush 320 moves close to the filter screen 200 to sweep away the dust on the filter screen 200. At the same time, the vacuum assembly 400 sucks the swept dust into the dust collection box 460 through the connecting pipe 440. The remaining dust falls into the dust receiving box 500. Then, the dust in the dust collection box 460 and the dust receiving box 500 can be cleaned periodically.

[0048] like Figure 1 and Figure 5 As shown, in some embodiments, the test chamber 1000 is a constant temperature and humidity test chamber. The constant temperature and humidity test chamber can test the performance of products or components under different temperature and humidity conditions to evaluate their stability and reliability in actual use environments. By simulating extreme environmental conditions, engineers can understand the working conditions of products in environments such as high temperature, low temperature, high humidity or low humidity, thereby improving and optimizing the products.

[0049] The constant temperature and humidity test chamber 1000 includes: a temperature control component 710, a humidity control component 720, a temperature measurement structure 730, a humidity measurement structure 740, and an operation display panel 750.

[0050] Temperature regulation component 710 is disposed in equipment cavity 140 and is used to regulate the temperature inside test cavity 120. For example, temperature regulation component 710 includes a heating system and / or a cooling system. When heating is required, temperature regulation component 710 will activate the heating system, such as a high-power resistance wire or electric heating element, to raise the temperature inside test cavity 120. Conversely, when cooling is required, temperature regulation component 710 will activate the cooling system, such as a cooling cycle formed by components like a compressor, condenser, and evaporator, to lower the temperature inside test cavity 120. Temperature regulation component 710 enables the temperature inside test cavity 120 to quickly reach and stabilize at a preset value to meet testing requirements.

[0051] A humidity control component 720 is disposed in the equipment cavity 140 and is used to regulate the humidity inside the test cavity 120. For example, the humidity control component 720 typically includes a humidification system and / or a dehumidification system. The humidification system can release water vapor or water mist into the test cavity 120 through a spray or steam humidifier to increase the humidity, while the dehumidification system condenses water vapor in the air into water droplets and discharges them outside the chamber through a condenser to reduce the humidity. The humidity control component 720 enables the humidity inside the test cavity 120 to be precisely controlled within a preset range to simulate different climatic environments.

[0052] A temperature measuring structure 730 is disposed in the test chamber 120 and is used to measure the temperature inside the test chamber 120. For example, the temperature measuring structure 730 can monitor the temperature inside the test chamber 120 in real time and feed the data back to the control system. The control system precisely adjusts the temperature regulating component 710 according to the feedback data to ensure that the temperature inside the test chamber 120 is stable at a preset value, thereby achieving precise temperature regulation.

[0053] A humidity measuring structure 740 is disposed in the test chamber 120 and is used to measure the humidity inside the test chamber 120. For example, the humidity measuring structure 740 can monitor the humidity inside the test chamber 120 in real time and feed the data back to the control system. The control system precisely adjusts the humidity regulating component 720 according to the feedback data to ensure that the humidity inside the test chamber 120 is stable at a preset value, thereby achieving precise humidity regulation.

[0054] The operation display panel 750 is located on the outer surface of the chamber 100 and serves as the interface for user interaction with the test chamber 1000. The temperature control component 710, humidity control component 720, temperature measurement structure 730, and humidity measurement structure 740 are all communicatively connected to the operation display panel 750. Thus, the measurement results of the temperature measurement structure 730 and humidity measurement structure 740 can be displayed on the operation display panel 750, allowing the user and / or control system to promptly know the environmental parameters of the test chamber 120 and perform corresponding operations based on the measurement results. Alternatively, the user can set test parameters (such as temperature, humidity, time, etc.) through the operation display panel 750 and monitor various data during the test process in real time, facilitating the provision of a constant temperature and humidity for the test chamber 120.

[0055] The constant temperature and humidity test chamber works together through the temperature regulation component 710, humidity regulation component 720, temperature measurement structure 730, humidity measurement structure 740 and operation display panel 750 to provide a precise temperature and humidity control environment to meet various testing and experimental needs.

[0056] like Figure 1 and Figure 5As shown, in some embodiments, the equipment chamber 140 includes a first chamber 142 and a second chamber 144 separated from each other. A temperature regulating component 710 is located in the first chamber 142, and a humidity regulating component 720 is located in the second chamber 144. The second chamber 144 is arranged vertically with the test chamber 120. The first chamber 142 is located on one side of the second chamber 144 and the test chamber 120 in the left-right direction. An operation display panel 750 corresponds to the first chamber 142 and is located on the front side of the chamber 100. A vent 160 is located on the rear side of the chamber 100. By placing the temperature regulating component 710 and the humidity regulating component 720 in different chambers, the internal structure of the test chamber 1000 becomes clearer and the layout more reasonable, reducing interference between components and facilitating stable operation of the test chamber 1000. Furthermore, when maintaining and repairing the temperature regulating component 710 and the humidity regulating component 720, the corresponding chambers can be opened individually without disassembling the entire equipment, facilitating maintenance work.

[0057] By arranging the second cavity 144 and the test cavity 120 vertically, the vertical space of the chamber 100 can be utilized more effectively, making the overall test chamber 1000 more compact. The first cavity 142 is located on one side of the second cavity 144 and the test cavity 120, which further optimizes the spatial layout and makes the overall structure of the test chamber 1000 more reasonable. The operation display panel 750 is located on the front side of the chamber 100, making it easier for users to observe and operate the equipment.

[0058] It is understood that the second chamber 144 can be located above the test chamber 120, or the test chamber 120 can be located above the second chamber 144. Regardless of whether the second chamber 144 is located above the test chamber 120 or the test chamber 120 is located above the second chamber 144, as long as it can ensure that the temperature and humidity conditions inside the test chamber 120 can be regulated by the entire equipment to meet the specific requirements of various tests or experiments.

[0059] like Figure 1As shown, in some embodiments, the humidity control component 720 includes a water tank 722, a water supply component 724, a water extraction component 726, and an atomizer 728. The water supply component 724 is located in the test chamber 120 and is used to supply water into the test chamber 120. The water extraction component 726 is connected to the water supply component 724 to pump water from the water tank 722 to the water supply component 724. The atomizer 728 is located in the equipment chamber 140 and is located upstream of the water supply component 724. When the humidity control component 720 starts to work, the water extraction component 726 extracts an appropriate amount of water from the water tank 722. The extracted water is transported to the water supply component 724, and the atomizer 728 atomizes the water into tiny water mists. The atomized water is evenly distributed into the test chamber 120 by the water supply component 724, increasing the humidity in the chamber and meeting the humidity conditions required for operation in the test chamber 120. It is understandable that the atomizer 728 is located inside the equipment chamber 140, which is relatively independent of the test chamber 120. Therefore, it is more convenient to maintain and replace the atomizer 728 and will not interfere with the environment inside the test chamber 120.

[0060] Of course, in other embodiments of this application, the atomizer 728 can also be located in the test chamber 120 and at the outlet of the water supply component 724. When the humidity regulating component 720 starts working, the water pumping component 726 draws an appropriate amount of water from the water tank 722. The drawn water is transported to the water supply component 724, and the water released by the water supply component 724 will be directly atomized by the atomizer 728. The atomized water is evenly distributed in the test chamber 120, increasing the humidity in the chamber and meeting the humidity conditions required for operation in the test chamber 120. It can be understood that the atomizer 728 is located directly in the test chamber 120, which can more effectively control the humidity level in the test chamber 120. When a rapid increase in humidity is required, this setting can respond quickly and reach the required humidity level.

[0061] Optionally, such as Figure 1 As shown, the water application component 724 can be formed as a water application pipe, and multiple spray holes are formed on the peripheral wall of the water application pipe. The multiple spray holes can be arranged in multiple rows and columns at intervals along the axial and circumferential directions of the water application pipe.

[0062] like Figure 1 and Figure 3 As shown, in some embodiments, the water tank 722 is removably mounted on the housing 100, allowing users to easily remove the water tank 722 from the housing 100 without disassembling other parts or performing complex operations. This makes cleaning, maintenance, and water filling of the water tank 722 more convenient.

[0063] In some embodiments, as Figure 1 and Figure 3As shown, the equipment cavity 140 is also provided with a push-pull box 760 and a slide rail structure 770. The water tank 722 is placed in the push-pull box 760. The slide rail structure 770 includes two spaced and parallel slide rails 772. The opposite sides of the push-pull box 760 slide and cooperate with the two slide rails 772 respectively.

[0064] Each slide rail 772 defines a groove 774 that opens towards each other. During disassembly and installation, the groove 774 provides a clear path for the push-pull box 760, allowing it to move smoothly and accurately in a predetermined direction without deviating from the track. Simultaneously, the groove 774 limits the range of movement of the push-pull box 760, ensuring it can only move within the groove 774. This helps prevent misalignment during movement, ensuring the safety and reliability of the push-pull box 760 during operation. And / or, the bottom of the push-pull box 760 is equipped with rotatable rollers 776. Each of the 772 sections has a mating groove 762 extending along the pull-out direction of the water tank 722. The roller 776 is positioned and fitted within the mating groove 762. The roller 776 significantly reduces the frictional resistance between the push-pull box 760 and the slide rail 772. Compared to direct sliding contact, the roller 776 has a lower coefficient of friction when rolling, making the movement of the push-pull box 760 on the slide rail 772 easier and smoother. At the same time, the roller 776 is positioned and fitted within the mating groove 762, which guides the rolling direction of the roller 776, facilitating the guidance of the movement direction of the push-pull box 760. This design also helps to limit the movement range of the push-pull box 760.

[0065] For example, such as Figure 1 and Figure 3 As shown, each slide rail 772 defines a slide groove 774 that opens toward each other, and the bottom wall of each slide groove 774 is formed with a mating groove 762.

[0066] In some embodiments, as Figure 1 and Figure 5 As shown, the equipment cavity 140 includes a first cavity 142 and a second cavity 144. The housing 100 includes a housing body 110, a first door 126, a second door 146, and a third door 148. The front side of the test cavity 120 is open. The first door 126 is rotatably connected to the housing body 110 to open and close the open side of the test cavity 120. The first door 126 is adapted to seal with the housing body 110. The second door 146 covers the front side of the first cavity 142, and the operation display panel 750 is provided on the second door 146. The third door 148 covers the front side of the second cavity 144.

[0067] Optionally, such as Figure 1As shown, the test chamber 120 has mounting brackets 122 on its opposite side walls. A push plate 124 can be placed between the two mounting brackets 122. The push plate 124 can provide a support platform for the material or object to be tested. The cooperation method between the push plate 124 and the mounting bracket 122 is not specifically limited. For example, the push plate 124 and the mounting bracket 122 can be pulled out together.
