[0009] And / or, the insulation structure includes an insulation bucket, an insulation block, and an insulation filling structure. The insulation bucket has a clearance opening through which the sample tube extends into the insulation bucket. The insulation block wraps around the outer periphery of the sample tube and seals the clearance opening. The insulation filling structure fills the inside of the insulation bucket.

[0010] In the preferred embodiment of the above-mentioned temperature control device, the outer shell includes a temperature control cup and two heat-insulating cover assemblies.

[0012] In the preferred embodiment of the above temperature control device, the heat preservation cover assembly includes a first heat preservation cover and a second heat preservation cover, the first heat preservation cover and the second heat preservation cover are connected to each other, and the first heat preservation cover has an addition hole.

[0013] In the preferred embodiment of the above temperature control device, the heat insulation cover assembly further includes a sealing element and a sealing ring. The sealing element is used to seal the addition hole. The sealing element includes a conical section, a sealing section and an installation head connected in sequence. The cross-sectional area of ​​the conical section gradually increases as it approaches the sealing section. The sealing section has a sealing groove. The sealing ring is installed in the sealing groove. The installation head is used to remove the sealing element.

[0014] In the preferred embodiment of the above temperature control device, the temperature control component further includes a temperature sensor, which is installed inside the insulation structure and is used to detect the temperature inside the insulation structure.

[0041] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0042] It should be noted that in the description of this utility model, terms such as "upper," "lower," "inner," and "outer," which indicate direction or positional relationship, are based on the direction or positional relationship shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0043] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0044] like Figures 1 to 6As shown, in a first aspect, the present invention provides a temperature control device, including a housing 10 and a temperature control component 20. The housing 10 has a receiving cavity 101, in which a temperature regulating liquid is disposed. The temperature control component 20 includes a heat insulation structure 21 and a first heat conducting structure 22. The heat insulation structure 21 is disposed in the receiving cavity 101. One end of the first heat conducting structure 22 is disposed in the temperature regulating liquid, and the other end extends into the heat insulation structure 21. The sample tube 1 is at least partially disposed in the heat insulation structure 21. The first heat conducting structure 22 is used to control the temperature of the sample tube 1.

[0045] With this configuration, the insulation structure 21 separates the sample tube 1 from the temperature regulating liquid, preventing the liquid from directly transferring temperature to the sample tube 1. One end of the first heat-conducting structure 22 extends into the temperature regulating liquid, and the other end extends into the insulation structure 21, transferring the temperature of the liquid to the insulation structure 21, thereby regulating the temperature within it. This regulation via the first heat-conducting structure 22 results in a slower temperature change within the insulation structure 21, allowing for precise temperature control and thus more accurate temperature control of the sample tube 1. This solution solves the problem of insufficient temperature control accuracy in existing temperature control devices.

[0046] In practical applications, the first heat-conducting structure 22 can be configured in various ways. For example, the first heat-conducting structure 22 can be configured as a heat-conducting rod or a heat-conducting pipe, etc. Such adjustments and changes to the configuration of the second heat-conducting structure 22 do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0047] In practical applications, various types of temperature regulating fluids can be used. For example, liquid nitrogen, liquid carbon dioxide, or liquid oxygen can be used. Such adjustments and changes to the type of temperature regulating fluid do not deviate from the principles and scope of this utility model and should be included within the protection scope of this utility model.

[0048] Preferably, the temperature regulating liquid is liquid nitrogen.

[0049] This design keeps the cost of the temperature regulating fluid low and prevents environmental pollution.

[0050] like Figure 1 As shown, the temperature control component 20 also includes a second heat-conducting structure 23. After the second heat-conducting structure 23 wraps around the sample tube 1, it is then placed inside the heat-insulating structure 21. One end of the first heat-conducting structure 22 that extends into the heat-insulating structure 21 abuts against the second heat-conducting structure 23.

[0051] With this arrangement, the first heat-conducting structure 22 and the second heat-conducting structure 23 come into contact, so as to transfer the temperature of the first heat-conducting structure 22 to the second heat-conducting structure 23. The second heat-conducting structure 23 wraps around the sample tube 1, making the temperature change of the sample tube 1 more uniform and enabling more precise control of the temperature of the sample tube 1.

[0052] In a specific embodiment of this utility model, the first heat-conducting structure 22 is a heat-conducting rod, the second heat-conducting structure 23 is a heat-conducting block, the heat-conducting block wraps around the sample tube 1, the heat-conducting rod transfers the temperature of the temperature regulating liquid to the heat-conducting block, and the heat-conducting block transfers the temperature evenly to the sample tube 1, making the temperature change of the sample tube 1 more uniform.

[0053] In one specific embodiment of this utility model, the outer shell 10 has a vacuum layer 102 inside, which serves as a temperature insulation layer.

[0054] In practical applications, the heating rod 30 and the first heat-conducting structure 22 are respectively connected to the second heat-conducting structure 23, thereby transferring the temperature of the first heat-conducting structure 22 or the heating rod 30 to the sample tube 1. The cross-sectional areas of the heating rod 30, the first heat-conducting structure 22, and the second heat-conducting structure 23 can be set in various ways, as long as the temperature of the heating rod 30 and the first heat-conducting structure 22 can be transferred to the second heat-conducting structure 23, thereby regulating the temperature of the sample tube 1. To make the temperature control of the sample tube 1 more precise, the ratio of the cross-sectional areas of the heating rod 30, the first heat-conducting structure 22, and the second heat-conducting structure 23 can be adjusted to achieve more precise temperature control of the sample tube 1.

[0055] It is conceivable that, in a specific embodiment of this utility model, during the installation of the heating rod 30, thermal grease is applied to the connection position between the heating rod 30 and the second thermally conductive structure 23 to make the temperature transfer more sensitive and faster.

[0056] Preferably, in a specific embodiment of the present invention, the temperature control component 20 further includes a heating rod 30, which is connected to the second heat-conducting structure 23. The ratio of the cross-sectional area of ​​the heating rod 30 to that of the first heat-conducting structure 22 is greater than or equal to 4 / 25, and the ratio of the cross-sectional area of ​​the first heat-conducting structure 22 to that of the second heat-conducting structure 23 is greater than or equal to 1 / 9.

[0057] With this configuration, the ratio of the cross-sectional area of ​​the heating rod 30 to that of the first heat-conducting structure 22 is greater than or equal to 4 / 25. This ensures that the heat transferred from the heating rod 30 to the second heat-conducting structure 23 can cause a change in the temperature inside the insulation structure 21. It also prevents the heat generated by the heating rod 30 from being neutralized by the temperature transferred from the first heat-conducting structure 22 when the ratio of the cross-sectional area of ​​the heating rod 30 to that of the first heat-conducting structure 22 is less than 4 / 25, thus preventing the heating rod 30 from regulating the temperature inside the insulation structure 21.

[0058] The ratio of the cross-sectional area of ​​the first heat-conducting structure 22 to the cross-sectional area of ​​the second heat-conducting structure 23 is greater than or equal to 1 / 9. This ensures effective temperature transfer from the first heat-conducting structure 22 to the second heat-conducting structure 23, guaranteeing that the temperature transferred from the first heat-conducting structure 22 to the second heat-conducting structure 23 can cause changes in the internal temperature of the insulation structure 21. This avoids the situation where the ratio of the cross-sectional area of ​​the first heat-conducting structure 22 to the cross-sectional area of ​​the second heat-conducting structure 23 is less than 1 / 9, in which case the temperature transferred by the first heat-conducting structure 22 cannot regulate the temperature of the second heat-conducting structure 23, thus preventing the first heat-conducting structure 22 from regulating the internal temperature of the insulation structure 21.

[0059] It is understood that, in a specific embodiment of this utility model, the cross-sectional areas of the heating rod 30, the first heat-conducting structure 22, and the second heat-conducting structure 23 are all circular, the ratio of the diameter of the heating rod 30 to the diameter of the first heat-conducting structure 22 is greater than or equal to 2 / 5, and the ratio of the diameter of the first heat-conducting structure 22 to the diameter of the second heat-conducting structure 23 is greater than or equal to 1 / 3.

[0060] This configuration ensures that the heat transferred from the heating rod 30 to the second heat-conducting structure 23 causes a temperature change within the insulation structure 21, thus guaranteeing that the heating rod 30 can regulate the temperature inside the insulation structure 21. Furthermore, it ensures effective temperature transfer from the first heat-conducting structure 22 to the second heat-conducting structure 23, guaranteeing that the temperature transferred from the first heat-conducting structure 22 to the second heat-conducting structure 23 causes a temperature change within the insulation structure 21.

[0061] In practical applications, the temperature control cup 11 has various specifications, and the temperature control component 20 can be fixed in the temperature control cup 11 in various ways. For example, the temperature control component 20 can be snapped onto the mouth of the temperature control cup 11, or the temperature control component 20 can be placed in the receiving cavity 101 of the outer shell 10, with the support plate 24 supporting the temperature control component 20, etc. Such adjustments and changes to the way the temperature control cup 11 and the temperature control component 20 are matched do not deviate from the principle and scope of this utility model, and should be included within the protection scope of this utility model.

[0062] like Figure 3As shown, in a specific embodiment of the present invention, the temperature control component 20 further includes a support plate 24, which is disposed at one end of the first heat-conducting structure 22 that extends into the temperature regulating liquid, and is used to support the temperature control component 20.

[0063] With this configuration, the support plate 24 is supported at the end of the first heat-conducting structure 22 that extends into the temperature regulating liquid, so that the temperature control component 20 can be supported in the temperature control cup 11 and will not tip over.

[0064] like Figure 2 As shown, the insulation structure 21 includes an insulation barrel 211, an insulation block 212, and an insulation filling structure 213. The insulation barrel 211 has an opening for the sample tube 1 to be inserted into the insulation barrel 211 through the opening. The insulation block 212 wraps around the outer periphery of the sample tube 1 and seals the opening. The insulation filling structure 213 fills the insulation barrel 211.

[0065] With this configuration, the thermal insulation filling structure 213 wraps around the outside of the first thermally conductive structure 22 and the second thermally conductive structure 23, allowing the temperature of the first thermally conductive structure 22 and the second thermally conductive structure 23 to be transferred to the sample tube 1, reducing temperature loss and ensuring precise temperature control of the sample tube 1. The thermal insulation block 212 wraps around the outer periphery of the sample tube 1 and seals the clearance opening, reducing temperature loss inside the thermal insulation structure 21 and making the temperature control inside the thermal insulation structure 21 more precise.

[0066] like Figure 3 As shown, in a specific embodiment of the present invention, the heat preservation bucket 211 includes an upper bucket 2111, a lower bucket 2112 and a bottom cover 2113. The diameter of the upper bucket 2111 is larger than the diameter of the lower bucket 2112. The bottom cover 2113 is fixedly connected to the first heat-conducting structure 22 and supports the upper bucket 2111 and the lower bucket 2112.

[0067] like Figure 1 and Figure 2 As shown, the outer casing 10 includes a temperature control cup 11 and two heat-insulating cover assemblies 12. The temperature control cup 11 has an opening that communicates with the receiving cavity 101, and the two heat-insulating cover assemblies 12 fit together to seal the opening to close the receiving cavity 101.

[0068] With this configuration, the insulation cover assembly 12 seals the opening of the temperature control cup 11, preventing the nitrogen gas in the temperature control cup 11 from evaporating, and the insulation cover assembly 12 also serves to keep the temperature warm.

[0069] In practical applications, the heat insulation cover assembly 12 can be set in a variety of different ways. For example, the heat insulation cover assembly 12 can be set as a whole, or two heat insulation cover assemblies 12 can be attached together to seal the opening, or multiple heat insulation cover assemblies 12 can be set to seal the opening, etc. All of these different ways of setting the heat insulation cover assembly 12 do not deviate from the principle and scope of this utility model, and should be included within the protection scope of this utility model.

[0070] Furthermore, the heat-insulating cover assembly 12 includes a cover body 121, a heat-insulating element 122, and a magnet 123. The cover body 121 has a groove on the side near the opening, and the heat-insulating element 122 is disposed in the groove and protrudes from the groove. The magnet 123 is disposed on one side of the cover body 121, and the heat-insulating element 122 is disposed on the side of the cover body 121 near the opening. The magnet 123 is used to attract the two cover bodies 121 together.

[0071] With this arrangement, magnet 123 is positioned on the side of lid 121 near another insulated lid assembly 12. The magnets of the two insulated lid assemblies 12 attract each other to seal the two lids 121 together, thereby blocking the opening of the temperature-controlled cup 11. Lid 121 has a groove on the side near the opening, within which an insulation element 122 is installed. The insulation element 122 provides thermal insulation, thus achieving the effect of keeping the temperature-controlled assembly 20 inside the receiving cavity 101 warm. The insulation element 122 protrudes from the groove, resulting in a greater thickness and better insulation performance.

[0072] In practical applications, the number of magnets 123 can be set in various ways. For example, two magnets 123 can be arranged sequentially on the side of the cover 121 near another heat-insulating cover assembly 12, or one magnet 123 can be arranged on the side of the cover 121 near another heat-insulating cover assembly 12, or multiple magnets 123 can be arranged sequentially on the side of the cover 121 near another heat-insulating cover assembly 12, and so on. Such adjustments and changes to the number of magnets 123 do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0073] In practical applications, the material of the insulation component 122 can be set in various ways. For example, the material of the insulation component 122 can be set as sponge, or the material of the insulation component 122 can be set as silicone, etc. Such adjustments and changes to the material of the insulation component 122 do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0074] As can be imagined, in a specific embodiment of this utility model, the heat preservation cover assembly 12 includes a first heat preservation cover 1201 and a second heat preservation cover 1202, the first heat preservation cover 1201 and the second heat preservation cover 1202 are connected to each other, and the first heat preservation cover 1201 has an addition hole 126.

[0075] With this arrangement, the first heat-insulating cover 1201 and the second heat-insulating cover 1202 fit together to seal the opening of the temperature control cup 11. The first heat-insulating cover 1202 has an inlet hole 126. When the amount of temperature regulating liquid in the temperature control cup 11 decreases, temperature regulating liquid can be added to the temperature control cup 11 through the inlet hole 126 to ensure that the temperature regulating liquid can transfer the temperature to the first heat-conducting structure 22.

[0076] Furthermore, as shown in the figure, the heat insulation cover assembly 12 also includes a sealing member 124 and a sealing ring 125. The sealing member 124 is used to seal the addition hole 126. The sealing member 124 includes a conical section 1241, a sealing section 1242 and an installation head 1243 connected in sequence. The cross-sectional area of ​​the conical section 1241 gradually increases as it approaches the sealing section 1242. The sealing section 1242 has a sealing groove, and the sealing ring 125 is installed in the sealing groove. The installation head 1243 is used to remove the sealing member 124.

[0077] With this setup, the installation head 1243 is removed to take out the sealing element 124, allowing temperature regulating fluid to be added into the filling hole 126. The sealing ring 125 is positioned within the sealing groove, improving the sealing effect of the sealing element 124 in sealing the filling hole 126 and reducing the evaporation of the temperature regulating fluid.

[0078] The cross-sectional area of ​​the tapered segment 1241 gradually increases towards the sealing segment 1242, resulting in a smaller cross-sectional area at the end of the tapered segment 1241 that inserts into the addition hole 126. This makes it easier and faster to push the tapered segment 1241 into the addition hole 126. Furthermore, the tapered segment 1241 provides a guiding effect for the installation of the sealing member 124. The sealing segment 1241 fits against the side wall of the addition hole 126 to seal it. The mounting head 1243 is located outside the addition hole 126 and is used to remove the sealing member 124.

[0079] like Figure 3 As shown, the temperature control assembly 20 also includes a temperature sensor 40, which is disposed inside the insulation structure 21 and is used to detect the temperature inside the insulation structure 21.

[0080] With this setup, the temperature sensor 40 detects the temperature inside the insulation structure 21, enabling precise control of the internal temperature. During temperature control, the heating rod 30 can be adjusted based on the detection results of the temperature sensor 40, thereby precisely regulating the internal temperature of the insulation structure 21.

[0081] It is conceivable that thermal grease be applied to the outer periphery of the temperature sensor 40 and then installed inside the insulation structure 21 to make the temperature transfer more sensitive and faster, and the temperature sensor 40 can respond more quickly to detect temperature changes inside the insulation structure 21.

[0082] Furthermore, in a specific embodiment of this utility model, the temperature control component 20 further includes a PTFE tube 50, a temperature sensor 40, and a heating rod 30. The PTFE tube 50 is at least partially inserted into the insulation structure 21, and the PTFE tube 50 is used to arrange the wiring of the temperature sensor 40 and the heating rod 30.

[0083] With this configuration, the wiring of the temperature sensor 40 and the heating rod 30 can extend from the PTFE tube 50 to power the temperature sensor 40 and the heating rod 30.

[0084] Furthermore, in a specific embodiment of the present invention, the heat insulation structure 21 includes a heat insulation barrel 211 and a heat insulation filling structure 213. The heat insulation filling structure 213 is filled inside the heat insulation barrel 211. The temperature control device also includes a sealing strip, which is wrapped around the outer periphery of the first heat-conducting structure 22 to fill the space between the first heat-conducting structure 22 and the heat insulation filling structure 213.

[0085] With this arrangement, the sealing strip is placed between the first heat-conducting structure 22 and the heat-insulating filling structure 213, thereby filling the gap between the first heat-conducting structure 22 and the heat-insulating filling structure 213, increasing the friction between the first heat-conducting structure 22 and the heat-insulating filling structure 213, preventing the first heat-conducting structure 22 from becoming loose, and the sealing strip can prevent the temperature regulating liquid in the receiving cavity from entering the heat-insulating structure 21 along the gap between the first heat-conducting structure 22 and the heat-insulating filling structure 213.

[0086] It is conceivable that, in one specific embodiment of this utility model, the sealing tape is made of PTFE tape. With this design, the PTFE tape possesses flexibility, compression resilience, and resistance to high and low temperatures, and it is also corrosion-resistant and not prone to aging. Therefore, the PTFE tape can better fill the gap between the first thermally conductive structure 22 and the thermal insulation filling structure 213, achieving the purpose of sealing and preventing loosening.

[0087] In a second aspect, a physical adsorption apparatus is provided, including a frame and the aforementioned temperature control device, wherein a sample tube 1 is disposed on top of the frame, and the temperature control device is disposed on the frame and is movable relative to the sample tube 1.

[0088] With this setup, after the temperature control device moves relative to the frame, sample tube 1 is inserted into the temperature control device. The temperature control device controls the temperature of the sample tube. After the temperature control is completed, the temperature control device moves relative to sample tube 1 to remove sample tube 1 from the temperature control device.

[0089] The technical solution of this utility model has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
