The terms used in the specification of this utility model herein are only for the purpose of describing specific embodiments and are not intended to limit this utility model.

[0027] The following further describes this utility model in detail with reference to the accompanying drawings.

[0028] Such as Figure 1 、 Figure 2 A high and low temperature pressurizing device shown, which includes a sealing assembly 100, a heat insulation assembly 200, and a temperature regulating assembly 300. A sealed cavity 01 is formed inside the sealing assembly 100. The heat insulation assembly 200 is arranged inside the sealed cavity 01. A temperature regulating cavity 02 is arranged inside the heat insulation assembly 200. The sealed cavity 01 is a sealed cavity body and can be isolated and sealed from the external environment through the sealing assembly 100. The temperature regulating cavity 02 is a non-sealed cavity body for arranging a test material S. The temperature regulating cavity 02 is in internal air pressure communication with the sealed cavity 01. The temperature regulating assembly 300 is provided with heat insulation materials, which can reduce the heat exchange between the heat insulation cavity and the inside of the sealed cavity 01 to maintain the temperature inside the temperature regulating cavity 02. The above-mentioned temperature regulating assembly 300 is arranged inside the temperature regulating cavity 02 to regulate the temperature inside the temperature regulating cavity 02; the temperature regulating assembly 300 includes a heating element 31 and a refrigerating element 32. The heating element 31 and the refrigerating element 32 are arranged alternately inside the temperature regulating cavity 02. The heating element 31 is used to raise the temperature inside the temperature regulating cavity 02, and the refrigerating element 32 is used to lower the temperature inside the temperature regulating cavity 02. And the way that the heating element 31 and the refrigerating element 32 are arranged alternately can, on the one hand, reduce the occupation of the internal space of the temperature regulating cavity 02, and on the other hand, can make the temperature inside the temperature regulating cavity 02 more uniform when adjusting.

[0029] Through the above design, when the temperature inside the temperature regulating cavity 02 is adjusted by the temperature regulating assembly 300, the heat insulation assembly 200 can play a heat insulation role for the temperature regulating cavity 02, which can greatly reduce the heat exchange between the temperature regulating cavity 02 and the inside of the sealed cavity 01. Thus, the interference of the temperature inside the sealed cavity 01 on the air pressure can be greatly reduced, so that the high and low temperature pressurizing device can test the test material S more accurately.

[0030] The technical details of each component will be introduced one by one below.

[0031] In some embodiments, such as Figure 1 、 Figure 2 、Figure 3 As shown in the figure, the above-mentioned sealing assembly 100 includes a housing 11 and a cover 12. The cover 12 is detachably connected to the housing 11. The cover 12 and the housing 11 can be made of stainless steel material. After the cover 12 and the housing 11 are closed, a sealed cavity 01 is formed. And a sealing ring 13 is provided between the housing 11 and the cover 12. The sealing ring 13 can be made of elastic materials such as rubber and silica gel. Since the connection between the cover 12 and the housing 11 is sealed, the sealed cavity is isolated from the external environment, which is convenient for separately adjusting the air pressure inside the sealed cavity 01 to meet the requirements of the test.

[0032] In some embodiments, as Figure 2 、 Figure 4 、 Figure 5 shown, the above-mentioned heat preservation assembly 200 includes a cylinder body 21, an upper cover 22 and a lower cover 23. The upper cover 22 and the lower cover 23 are respectively non-sealingly closed at opposite ends of the cylinder body 21, so that the air pressure inside the temperature control cavity 02 can change with the change of the air pressure inside the sealed cavity 01. And the split design of the cylinder body 21, the upper cover 22 and the lower cover 23 can facilitate placing the test material S inside the temperature control cavity 02. The cylinder body 21, the upper cover 22 and the lower cover 23 can all be made of heat preservation and heat insulation materials, which can effectively reduce the heat exchange between the inside of the temperature control cavity 02 and the sealed cavity 01, and further reduce the influence of temperature on the air pressure inside the sealed cavity 01.

[0033] In some embodiments, as Figure 4 、 Figure 5 shown, the above-mentioned cylinder body 21 includes a plurality of assembled bodies 211, and the plurality of assembled bodies 211 are spliced together to form the above-mentioned cylinder body 21. In practical applications, the cylinder body 21 formed by the above-mentioned plurality of assembled bodies 211 can further facilitate placing the test material S inside the temperature control cavity 02.

[0034] In some embodiments, the above-mentioned heating element 31 includes a first spiral part 311, a first end part 312 and a second end part 313. The first spiral part 311 is arranged inside the temperature control cavity 02 for increasing the heating area. The first end part 312 and the second end part 313 are both arranged on the upper cover 22 or the lower cover 23. The first end part 312 and the second end part 313 are used to fix the heating element 31 and connect to the power supply.

[0035] As Figure 4 、 Figure 5 shown, both the first end part 312 and the second end part 313 are connected to the lower cover 23. Of course, the first end part 312 and the second end part 313 can also be both connected to the upper cover 22. Arranging both the first end part 312 and the second end part 313 on the lower cover 23 can shorten the connection line of the heating element 31, making the structure inside the high and low temperature pressurizing device more compact. The spiral structure of the first spiral part 311 can adjust the temperature inside the temperature control cavity 02 more evenly.

[0036] In some embodiments, the refrigerating member 32 includes a second spiral portion 321, a third end portion 322, and a fourth end portion 323. The second spiral portion 321 is disposed inside the temperature adjustment chamber 02 to increase the refrigerating area. The third end portion 322 and the fourth end portion 323 are both disposed on the upper cover 22 or the lower cover 23 to fix the refrigerating member 32 and connect to an external power source.

[0037] As Figure 4 , Figure 5 shown, both the third end portion 322 and the fourth end portion 323 are disposed on the lower cover 23. Of course, the third end portion 322 and the fourth end portion 323 can also be disposed on the upper cover 22. Disposing both the third end portion 322 and the fourth end portion 323 on the lower cover 23 can greatly shorten the connection line of the refrigerating member 32, making the structure inside the high and low temperature pressurizing device more compact. The spiral structure of the second spiral portion 321 can more evenly adjust the temperature inside the temperature adjustment chamber 02.

[0038] In some embodiments, as Figure 4 , Figure 5 shown, the heating member 31 and the refrigerating member 32 are synchronously wound to form a double-layer spiral structure 03. The double-layer spiral structure 03 is disposed opposite to the side wall of the heat preservation chamber and can surround the test material S. Synchronously winding the heating member 31 and the refrigerating member 32 can greatly reduce the occupation of the internal space of the temperature adjustment chamber 02 by the heating member 31 and the refrigerating member 32. In practical applications, synchronously winding the heating member 31 and the refrigerating member 32 can also make the heating source and the refrigerating source inside the temperature adjustment chamber 02 in a state close to overlap, effectively avoiding uneven temperature inside the temperature adjustment chamber 02 due to too large a distance between the heating source and the refrigerating source. The closer the heating source and the refrigerating source are, the more uniform the temperature adjustment is.

[0039] In some embodiments, as Figure 4 , Figure 5 shown, the heating member 31 and the refrigerating member 32 form two of the above double-layer spiral structures 03, and the two double-layer spiral structures 03 are respectively located on opposite sides inside the temperature adjustment chamber 02. In practical applications, the above design can more evenly and quickly adjust the temperature inside the temperature adjustment chamber 02, which is beneficial to improving the accuracy of the high and low temperature pressurizing device for testing the test material S.

[0040] In some embodiments, as Figure 6As shown, the high and low temperature pressurizing device further includes an observation component 400. The observation component 400 is connected to the sealing component 100 and the heat preservation component 200, and is used to observe the test material S inside the temperature adjustment chamber 02 during the test. The observation component 400 is in optical communication with the inside of the temperature adjustment chamber 02, and the user can observe the changes of the test material S inside the temperature adjustment chamber 02 through the observation component 400.

[0041] In some embodiments, as Figure 6 shown, the high and low temperature pressurizing device further includes a monitoring component 500. The monitoring component 500 includes a temperature monitoring device and a pressure monitoring device. The temperature monitoring device is provided with a temperature sensor, and the temperature sensor is arranged inside the temperature adjustment chamber 02. The pressure monitoring device is provided with a pressure sensor, and the pressure sensor is arranged inside the sealed chamber 01. Through the above design, the temperature and pressure of the environment where the test material S is located can be adjusted, and thus it is convenient to test the test material S.

[0042] In the description of the present invention, it should also be noted that, unless otherwise clearly defined and limited, the terms "set", "installed", "connected", and "connected" should be understood in a broad sense. For example, it 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 directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0043] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of another identical element in the process, method, article or device including the said element.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
