[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figure 1-5 An embodiment of this utility model is provided: an adjustable temperature and humidity chamber, including a base 1, a chamber 2 fixedly installed on the upper surface of the base 1, an inner chamber 3 for placing products for testing is provided inside the chamber 2, and inner hanging plates 4 are fixedly installed on both sides of the inner wall of the inner chamber 3, with no less than two sets of inner hanging plates 4 on the same side.

[0023] Please refer to the instruction manual for details. Figure 3 As shown, each inner hanging plate 4 has several hanging grooves 5, which are distributed longitudinally at equal intervals. A support strip 6 is provided between two inner hanging plates 4 on the same side. A hanger (covered in the figure, not shown) that is adapted to the direction of the hanging groove 5 is fixedly installed on the outer wall of the back of the support strip 6. A load plate 7 is placed between the upper surfaces of the two support strips 6.

[0024] This structural design allows for the placement and support of products to be tested via the loading plate 7, thereby ensuring the normal placement and use of the constant temperature and humidity chamber of this utility model.

[0025] Since the support plate 7 is supported by two support strips 6, when it is necessary to adjust the distance between the two support plates 7, the upper support plate 7 can be removed, and then the hangers of the two upper support strips 6 can be pulled out from the suspension grooves 5. Then, the two support strips 6 are moved upward. When they are moved to a suitable height, the hangers of the support strips 6 can be suspended in the suspension grooves 5 of the inner hanging plate 4 to complete the positioning of the support strips 6. Finally, the support plate 7 is placed between the two adjusted support strips 6 to complete the distance adjustment between the two support plates 7.

[0026] In this embodiment, in order to ensure the normal use of the constant temperature and humidity chamber of this utility model, a low temperature chamber 8 is provided on the back of the inner chamber 3 and inside the chamber body 2. An evaporator 11 is fixedly installed at the bottom of the inner chamber 8. A humidifier mounting position 12 is provided on the back of the low temperature chamber 8. A humidifier (not shown in the figure) is installed on the humidifier mounting position 12. The air can be humidified by the humidifier.

[0027] Furthermore, a water tank 13 is fixedly installed inside the bottom of the base 1, and the water outlet of the water tank 13 has two heat dissipation water ducts 14 connected in series through pipes.

[0028] Furthermore, the outlet of one of the cooling water drains 14 is connected to the evaporator 11 via a pipe, and the outlet of the evaporator 11 is connected to the inlet of the water tank 13 via a pipe and a circulation pump.

[0029] In this structural design, the water tank 13 stores refrigerant during use. After the refrigerant is discharged, it is cooled down by two heat dissipation water ducts 14 and then enters the evaporator 11. The evaporator 11 evaporates the low-temperature and low-pressure liquid refrigerant into a gaseous state, absorbing heat from the surrounding environment, thereby achieving a cooling effect and keeping the air in the low-temperature chamber 8 at a low temperature.

[0030] The low-temperature air inside the low-temperature chamber 8 can then be humidified by the humidifier, thus ensuring that the air inside the low-temperature chamber 8 is in a low-temperature and high-humidity state.

[0031] In this embodiment, in order to inject the low-temperature and high-humidity gas inside the low-temperature chamber 8 into the interior of the inner chamber 3 and ensure the constant temperature and humidity test effect of the inner chamber 3, an air inlet pump 9 is fixedly installed inside the top of the low-temperature chamber 8, and an air guide vane 10 is fixedly installed at the air outlet of the air inlet pump 9. The air guide vane 10 is interconnected with the inner chamber 3.

[0032] The low-temperature and high-humidity gas inside the low-temperature chamber 8 can be injected into the inner chamber 3 by the air inlet pump 9, thereby ensuring the low temperature and humidity state inside the inner chamber 3 and ensuring the normal use effect of the constant temperature and humidity chamber of this utility model.

[0033] In actual use, temperature and humidity sensors are installed inside the inner chamber 3 to sense and detect the temperature and humidity inside the inner chamber 3.

[0034] In this embodiment, in order to perform external testing and sealing treatment on the inner chamber 3, a sealing door is provided on the outside of the inner chamber 3. The sealing door is hinged to the box body 2. A viewing window 15 is provided on the sealing door. Through the viewing window 15, the changes and conditions of the internal test products can be observed more directly, improving the intuitive and visual use effect. Test data can be observed and recorded at any time, making it convenient to use.

[0035] Working principle: When using this utility model, the inner chamber 3 of the chamber can be opened through the sealed door, and then the product to be tested can be placed on the carrying plate 7 of the inner chamber 3. The carrying plate 7 can be used to place and support the product to be tested, thereby ensuring the normal placement and use of the constant temperature and humidity chamber of this utility model.

[0036] During constant temperature and humidity testing, the refrigerant inside the water tank 13 is discharged and cooled down through two heat dissipation ducts 14 before entering the evaporator 11. The evaporator 11 evaporates the low-temperature, low-pressure liquid refrigerant into a gaseous state, absorbing heat from the surrounding environment, thereby achieving a cooling effect and keeping the air in the low-temperature chamber 8 at a low temperature.

[0037] The low-temperature air inside the low-temperature chamber 8 can then be humidified by the humidifier, thereby ensuring the low-temperature and high-humidity state of the air inside the low-temperature chamber 8.

[0038] The liquid in the evaporator 11 can be returned to the water tank 13 by the circulation pump, thus performing circulating liquid cooling.

[0039] Then, the low-temperature and high-humidity gas inside the low-temperature chamber 8 can be injected into the inner chamber 3 through the air inlet pump 9, thereby ensuring the low temperature and humidity state inside the inner chamber 3 and ensuring the normal use effect of the constant temperature and humidity chamber of this utility model.

[0040] Since the support plate 7 is supported by two support strips 6, when it is necessary to adjust the distance between the two support plates 7, the upper support plate 7 can be removed, and the hangers of the two upper support strips 6 can be pulled out from the suspension grooves 5. Then, the two support strips 6 are moved upward. When they are moved to a suitable height, the hangers of the support strips 6 can be suspended in the suspension grooves 5 of the inner hanging plate 4 to complete the positioning of the support strips 6. Finally, the support plate 7 is placed between the two adjusted support strips 6 to complete the distance adjustment between the two support plates 7.

[0041] This temperature and humidity chamber features a design where the spacing of the internal support plates can be freely adjusted according to actual usage. This dynamic adjustability of the internal support plate layout allows for dynamic adjustment of the plate spacing based on the height of different test products, making it suitable for placing and testing a wider range of products. Compared to traditional fixed internal structures, this invention offers more flexible plate adjustment, effectively improving the overall height and dimensional applicability. The dynamic spacing adjustment based on actual product height provides greater flexibility and a wider range of applicable dimensions, effectively avoiding the limitations of traditional fixed structures. This enhances the flexibility and convenience of use, and the overall adjustment structure is simple, requiring only the removal of the hanging clips for quick and easy adjustment, making it suitable for widespread adoption.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
