The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope under which the present utility model can be implemented.
[0033] As Figures 1 - 6 shown, the present utility model provides a low-temperature maintaining device for a confocal micro-Raman spectrometer, including a low-temperature maintaining component 3. The low-temperature maintaining component 3 is connected to an external refrigeration device, so that the inside of the low-temperature maintaining component 3 is kept at a low temperature, thereby reducing the deformation and volatilization of low-temperature materials.
[0034] The low-temperature maintaining component 3 includes a heat-insulating component 301, a sealing component 302, and a heat-conducting component 303. The sealing component 302 seals the mouth of the heat-insulating component 301, which is used to improve the heat-insulating performance and prevent the volatilization or evaporation of materials. The heat-conducting component 303 transmits energy to the inside of the heat-insulating component 301, and conducts heat to the inside of the heat-insulating component 301 through the heat conductivity of the heat-conducting component 303, so as to keep the low-temperature materials in the heat-insulating component 301 at a low temperature. The heat-conducting component 303 can be a metal tube or a heat-conducting sheet, and mainly cools down through heat conductivity.
[0035] The thermal insulation component 301 includes an outer heat insulation layer 3011 and an inner heat conduction layer 3012. The provided heat insulation layer 3011 and heat conduction layer 3012 form a box body for placing the material to be detected. Between the heat insulation layer 3011 and the heat conduction layer 3012 is a circulation chamber 3013. The purpose of setting the circulation chamber 3013 is to facilitate the installation of the heat conduction component 303 and form a heat-insulated space through the circulation chamber 3013 to reduce the heat transfer from the heat conduction layer 3012 to the heat insulation layer 3011. The heat conduction component 303 is arranged inside the circulation chamber 3013, and the outer surface of the heat conduction component 303 is lapped with the inner wall of the heat conduction layer 3012. Thus, when the low-temperature medium passes through the inside of the heat conduction component 303, the heat conduction component 303 will absorb a large amount of heat and cool down, and the low temperature will be transmitted to the heat conduction layer 3012 through the lap between the heat conduction component 303 and the heat conduction layer 3012, thereby keeping the low-temperature material in the thermal insulation component 301 at a low temperature.
[0036] In some embodiments, the thermal insulation component 301 of the present utility model further includes an observation lens 3014. The observation lens 3014 seals the bottom of the circulation chamber 3013 and the heat conduction layer 3012. The purpose of setting the observation lens 3014 is not only to seal the bottom of the heat insulation layer 3011 but also to achieve light transmission, so that the laser of the Raman spectroscopy device can be mapped to the receiver at the bottom when shooting towards the sample, thereby forming a Raman spectrum.
[0037] In some embodiments, the sealing component 302 of the present utility model includes a heat insulation cover 3021, and a light transmission lens 3024 is arranged at the center of the heat insulation cover 3021. The function of setting the light transmission lens 3024 is similar to that of the observation lens 3014, and is used to enable the laser of the Raman spectrometer to enter the inside of the thermal insulation component 301 to irradiate the material. At the same time, it can also seal the top of the thermal insulation component 301 and improve the thermal insulation performance.
[0038] In some embodiments, both the observation lens 3014 and the light transmission lens 3024 of the present utility model are colorless transparent glasses, which are used to improve the light transmission, reduce the loss of the laser energy emitted by the Raman spectrometer, and enable the microscope to directly observe the material. Heat insulation coatings are arranged on the outer surfaces of the observation lens 3014 and the light transmission lens 3024. By covering the heat insulation coatings on the outer surfaces of the observation lens 3014 and the light transmission lens 3024, the observation lens 3014 and the light transmission lens 3024 also have good heat insulation and thermal insulation performance, reducing the amount of low temperature transmitted outward through the observation lens 3014 and the light transmission lens 3024. At the same time, the heat insulation coating can improve the strength of the observation lens 3014 and the light transmission lens 3024, reducing the possibility of the observation lens 3014 and the light transmission lens 3024 being broken due to low temperature.
[0039] In some embodiments, a sealing plug 3022 is provided at the bottom of the heat insulation cover 3021 of the present utility model, and the outer surface of the sealing plug 3022 can be lapped with the inner wall of the heat conduction layer 3012. When the heat insulation cover 3021 seals the mouth of the heat preservation component 301, the observation groove 3023 will extend into the interior of the heat preservation component 301, thereby improving the sealing performance. The sealing plug 3022 is an equilateral trapezoid, so that when the heat insulation cover 3021 is sealed, the sealing plug 3022 can more easily enter the interior of the heat preservation component 301. An observation groove 3023 is provided at the center of the sealing plug 3022, and the provided observation groove 3023 is used to avoid blocking the light of the light-transmitting lens 3024.
[0040] In some embodiments, the heat insulation cover 3021 of the present utility model is made of plastic material, so as to reduce the weight of the heat insulation cover 3021, and the plastic material has poor thermal conductivity, which can achieve a good heat preservation and insulation effect. The interior of the heat insulation cover 3021 is filled with heat insulation cotton, which is used to further reduce the weight of the heat insulation cover 3021 and improve the heat insulation and heat preservation performance of the heat insulation cover 3021.
[0041] In some embodiments, the heat conduction component 303 of the present utility model includes a metal copper tube 3031. The metal copper tube 3031 is a wavy tube that is circularly arranged inside the circulation chamber 3013. The metal copper tube 3031 is arranged in a wavy shape inside the circulation chamber 3013, which can effectively increase the contact area between the metal copper tube 3031 and the circulation chamber 3013, thereby increasing the heat release amount of the metal copper tube 3031 to the circulation chamber 3013 and improving the heat transfer efficiency.
[0042] Both ends of the metal copper tube 3031 are provided with conduit connectors 3032. The two conduit connectors 3032 both extend to the outer surface of the heat insulation layer 3011. The provided conduit connectors 3032 are quick connectors or threaded connectors, which are used to improve the convenience of connection. The conduit connectors 3032 can be connected to an external refrigeration device. When the refrigeration device performs refrigeration, the low-temperature medium enters the interior of the metal copper tube 3031 from the position of the conduit connectors 3032 for circulation, so that the circulation chamber 3013 is in a low-temperature state. When the circulation chamber 3013 is at a low temperature, heat will be conducted to the heat conduction layer 3012, so that the materials inside the heat preservation component 301 are kept at a low temperature.
[0043] In some embodiments, the present utility model further includes an external confocal micro-Raman spectrometer body 1. The confocal micro-Raman spectrometer body 1 is formed by coupling a microscope and a Raman spectrometer. The coupling technology belongs to the prior art and will not be elaborated in the application documents. A sample support platform 2 is installed on the confocal micro-Raman spectrometer body 1. The low-temperature holding component 3 is arranged on the sample support platform 2. The sample support platform 2 is also a conventional structure and is used to support the sample or the glass slide carrying the sample.
[0044] In some embodiments, a limiting groove 201 is provided on the sample support platform 2 of the present utility model. The low-temperature maintaining component 3 is limited in the installation angle by the limiting groove 201, so that the laser of the Raman spectrometer can better act on the sample inside the heat-insulating component 301. A light-transmitting groove 202 is provided at the center of the limiting groove 201. The provided light-transmitting groove 202 is used for light transmission. After the laser of the Raman spectrometer penetrates through the sample, it can act on the receiver to form a Raman spectrum.
[0045] The specific use process of the present utility model is as follows:
[0046] Place the heat-insulating component 301 on the top of the sample support platform 2, and limit the heat-insulating component 301 by the limiting groove 201;
[0047] Place the sample at the inner bottom of the heat-insulating component 301, and focus on the position of the sample and cool it through the heat conduction component 303;
[0048] After focusing, according to the above steps, directly cover the sealing component 302 or connect the heat conduction component 303 with the refrigeration device after covering the sealing component 302, so that the low-temperature medium generated by the refrigeration device circulates inside the heat conduction component 303, and thus the inside of the heat-insulating component 301 is in a low temperature state through the heat conduction of the heat conduction component 303;
[0049] After the detection is completed, separate the refrigeration device and the heat conduction component 303 according to the properties of the material, and completely discharge the low-temperature medium in the heat conduction component 303, or keep the refrigeration of the refrigeration device to keep the material at a low temperature, and take out the material for storage.
[0050] In summary, for the low-temperature maintaining device of the confocal micro-Raman spectrometer of the present utility model, by providing the heat-insulating component 301 above the sample support platform 2, and providing the sealing component 302 at the mouth of the heat-insulating component 301 to seal the heat-insulating component 301, and at the same time providing the heat conduction component 303 inside the heat-insulating component 301, connecting the heat conduction component 303 with the refrigeration device to transmit the low-temperature energy to the inside of the heat-insulating component 301, so that the sample placed inside the heat-insulating component 301 is kept at a low temperature, achieving the effect of facilitating the detection of low-temperature materials.
[0051] Meanwhile, in the present utility model, the housing of the heat preservation component 301 is composed of a heat insulation layer 3011 and a heat conduction layer 3012, and a circulation chamber 3013 is arranged between the heat insulation layer 3011 and the heat conduction layer 3012 for installing a heat conduction component 303. When the heat conduction component 303 transfers energy to the inside of the heat preservation component 301, the heat insulation layer 3011 is used to isolate heat dissipation, and the heat conduction layer 3012 is used to conduct energy to the inside of the heat preservation component 301, achieving the purpose of improving the heat preservation effect and reducing heat loss.
[0052] An observation lens 3014 is arranged at the bottom of the heat insulation layer 3011 and a light-transmitting lens 3024 is arranged in the middle of the heat insulation cover 3021. During detection, both the observation lens 3014 and the light-transmitting lens 3024 are used for light transmission, enabling Raman laser to act on the material inside the heat preservation component 301 and allowing the microscope to observe the material. Moreover, through the cooperation of the observation lens 3014 and the light-transmitting lens 3024, the mouth of the heat preservation component 301 is completely sealed, improving the heat preservation performance, preventing material volatilization, and enhancing safety.
[0053] Therefore, the present utility model effectively overcomes various drawbacks in the prior art and has high industrial utilization value.
