[0034] like Figure 1-Figure 7 As shown, the present invention provides a confocal microscope for Raman detection, comprising a support mechanism 1, a microscope optical unit 2, and a Raman spectrometer body 3. The support mechanism 1 supports the microscope optical unit 2, which is coupled to the Raman spectrometer body 3. The Raman spectrometer body 3 emits a laser beam toward a material to generate a Raman spectrum. The structure and coupling method of the microscope optical unit 2 and the Raman spectrometer body 3 are both prior art and are therefore not further described in this application document.

[0035] The support mechanism 1 is a frame with legs. The upper portion of the frame supports the microscope optical section 2. A cavity 101 is provided within the frame. An air outlet 102 is provided on the side of the cavity 101 facing the microscope optical section 2, and an air inlet 103 is provided on the other side of the cavity 101. Air enters through the air inlet 103 and is discharged through the air outlet 102.

[0036] A heating component 104 and an air supply component 105 are installed inside the cavity 101. The heating component 104 generates heat when powered on, while the air supply component 105 draws air from the air inlet 103 and blows the air toward the heating component 104. The air heated by the heating component 104 is then blown toward the optical lens of the microscope optical section 2 from the air outlet 102 to achieve a defogging effect.

[0037] After experiments, it was found that the heating temperature of the heating component 104 is between 35 degrees and 45 degrees. If the temperature is too low, it will not be able to quickly defog the lens. If the temperature is too high, it will easily cause damage to the optical lens. In order to achieve temperature control, a temperature sensor can be added to the mouth of the air outlet 102 to monitor the temperature, thereby controlling the heating temperature of the heating component 104.

[0038] The heating component 104 and the air supply component 105 can be controlled independently, or can be connected to a main board inside the Raman spectrometer body 3 and controlled by a computer.

[0039] In some embodiments, an airflow channel 106 is provided between the heating component 104 and the air supply component 105. The purpose of providing the airflow channel 106 is to increase the distance between the heating component 104 and the air supply component 105, thereby increasing the airflow range, so that the airflow can better drive the heat emitted by the heating component 104 to the optical lenses of the microscope optical section 2. At the same time, increasing the distance between the heating component 104 and the air supply component 105 can effectively reduce the impact of the heat from the heating component 104 on the air supply component 105. The heating component 104 is located at the end of the airflow channel 106 near the air outlet 102, and the air supply component 105 is located at the end of the airflow channel 106 near the air inlet 103.

[0040] In some embodiments, the heating component 104 includes two support and insulation frames 1041, each of which has a plurality of connecting flanges 1042 mounted on its outer surface. The connecting flanges 1042 are connected to the inner wall of the cavity 101, making it convenient to mount the support and insulation frames 1041 on the inner wall of the cavity 101. Furthermore, the connecting flanges 1042 ensure that a gap is left between the surface of the support and insulation frames 1041 and the inner wall of the cavity 101, preventing direct contact.

[0041] Several heating rods 1043 are fixedly connected to the inner wall of the support and insulation frame 1041. By arranging multiple heating rods 1043 to heat the air simultaneously, the heating speed can be effectively increased, thereby improving the demisting efficiency. Several heating rods 1043 are connected in parallel, so that if one heating rod 1043 is damaged, the overall demisting effect will not be significantly affected.

[0042] A wiring hole 1045 is provided on the axis of one of the connecting flanges 1042, and the power cord of the heating rod 1043 passes through the wiring hole 1045 to the interior of the supporting thermal insulation frame 1041, so as to facilitate the line of the heating rod 1043 to pass through the cavity of the supporting thermal insulation frame 1041 and connect to the power supply; at the same time, the supporting thermal insulation frame 1041 can also protect the line of the heating rod 1043 to prevent the line from being directly affected by heating and accelerating the aging of the outer skin.

[0043] In some embodiments, each heating rod 1043 is provided with a thermal insulation gasket 1044 at both ends. The thermal insulation gasket 1044 separates the two ends of the heating rod 1043 from the inner wall of the support thermal insulation frame 1041, thereby reducing the heat directly transferred to the support thermal insulation frame 1041 when the heating rod 1043 is heated. In addition, the gap between the outer surface of the support thermal insulation frame 1041 and the inner wall of the cavity 101 is combined to prevent the outer surface of the support mechanism 1 from becoming too hot, thereby protecting the operator. At the same time, in order to improve safety. The thermal insulation gasket 1044 is made of insulating material, and the wire of the heating rod 1043 passes through the middle of the thermal insulation gasket 1044 and enters the cavity tube in the support thermal insulation frame 1041.

[0044] In some embodiments, the air supply component 105 includes a support roller 1051 , one end of which is provided with a bearing seat 1052 to reduce friction at the connection between the support roller 1051 and the interior of the cavity 101 and enhance the rotational flexibility of the support roller 1051 ; the other end of the support roller 1051 is provided with a power output device 1053 . When the power output device 1053 is energized, the output end drives the support roller 1051 to rotate. Depending on the usage scenario, the power output device 1053 can be a conventional motor or motor, or a servo motor or stepper motor capable of precisely controlling the speed. The bearing seat 1052 and the power output device 1053 are both connected to the inner wall of the cavity 101, thereby supporting the support roller 1051.

[0045] The outer surface of the support roller 1051 is provided with a number of equally distributed air supply blades 1054. When the support roller 1051 rotates, the air supply blades 1054 will push the air toward the heating component 104, thereby bringing the heat emitted by the heating component 104 to the optical lens of the microscope optical part 2, and achieving defogger by heating the optical lens.

[0046] In some embodiments, a protective wire groove 1055 is provided on the outer surface of the power output device 1053, and the power cord of the power output device 1053 is led out from the inside of the protective wire groove 1055, so that the circuit of the power output device 1053 can also be protected, preventing the exposed power cord or signal cord from being blown when the air supply blades 1054 drive the air flow, and causing the power cord or signal cord to be entangled between the air supply blades 1054.

[0047] In some embodiments, a ventilation plate 1031 is provided on the air inlet 103. The outer surface of the ventilation plate 1031 is in contact with and fixed to the inner wall of the air inlet 103. A dust filter 1033 is provided on the side of the ventilation plate 1031 facing the air supply component 105. The dust filter 1033 completely covers the ventilation holes on the ventilation plate 1031, thereby filtering the air entering through the ventilation plate 1031 and reducing the amount of dust in the air that enters the cavity 101. When a large amount of dust in the air enters the cavity 101, the dust is inevitably carried by the airflow and blown toward the optical lens of the microscope optical section 2. Although demisting is achieved, the dust will inevitably contaminate the optical lens of the microscope optical section 2, causing new problems.

[0048] In some embodiments, an embedding groove 1032 is provided on the side of the ventilation plate 1031 facing the dust filter element 1033, and the dust filter element 1033 is installed inside the embedding groove 1032, so that the dust filter element 1033 is limited by the embedding groove 1032, ensuring that the dust filter element 1033 can accurately cover the ventilation holes on the ventilation plate 1031, and the outer surface of the dust filter element 1033 is flush with the outer surface of the ventilation plate 1031.

[0049] The specific use process of this utility model is as follows:

[0050] First, before conducting the experiment, the heating component 104 is turned on for preheating via a separate switch or computer control software;

[0051] At the same time, the power output device 1053 is turned on, and the air supply blades 1054 are driven by the power output device 1053 to drive air to enter from the air inlet 103 and be discharged from the air outlet 102;

[0052] Finally, when the experiment is about to begin, the power output device 1053 and the heating rod 1043 are turned off at the same time to ensure that the power output device 1053 does not continue to work and interfere with the observation of the sample.

[0053] In summary, the utility model is applied to the confocal microscope used in Raman detection, by arranging a cavity 101 inside the supporting mechanism 1, and opening an air outlet 102 and an air inlet 103 on the supporting mechanism 1 to communicate with the cavity 101, and installing a heating component 104 and an air supply component 105 inside the cavity 101 respectively. The air supply component 105 drives the air flow so that the heat emitted by the heating component 104 is blown toward the optical lens of the optical part 2 of the microscope, thereby achieving the effect of improving the speed of dissipation of fog on the optical lens of the optical part 2 of the microscope.

[0054] At the same time, the utility model sets a dust filter element 1033 on the inner wall of the air inlet 103, and filters the dust in the air through the dust filter element 1033 to reduce the dust particles in the air flow blowing toward the optical lens of the microscope optical part 2, thereby preventing dust particles from contaminating the optical lens of the microscope optical part 2.

[0055] Therefore, the utility model effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
