Technical Field

[0001] This utility model relates to the field of optical instrument technology, and in particular to a housing for optical instruments. Background Technology

[0002] Optical instruments are specialized and precise scientific instruments with stringent environmental requirements. The operating temperature must be maintained at 20±1℃, the humidity below 50%RH, and the air must be kept constantly clean. To meet these requirements, optical instruments are typically used in clean laboratories with constant temperature and humidity.

[0003] However, in some cases, the temperature, humidity, and cleanliness of the user's location may not meet the requirements for use, rendering the optical instrument unusable. If it is used against its will, fluctuations in ambient temperature and humidity will lead to inaccurate test results. Furthermore, dust in the air may settle inside the optical instrument, contaminating optical components, lenses, or samples, ultimately causing damage to the components. Utility Model Content

[0004] This utility model mainly solves the technical problem that optical instruments cannot be used or the test results are inaccurate when the temperature, humidity, cleanliness and other conditions of the site do not meet the requirements. It proposes a housing for optical instruments so that the optical instruments can be used normally under any temperature, humidity and cleanliness conditions, and the test results of the optical instruments are accurate.

Detailed Implementation

[0029] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0030] like Figure 1-3 As shown in the figure, an embodiment of the present invention provides a housing for an optical instrument, comprising: an optical instrument housing and a circulating fan 8, a filter element 9, a particle sensor 10, a circulating air duct 11, and a temperature sensor 6 disposed within the optical instrument housing.

[0031] The enclosure includes a support frame 2 and insulation layers 5 disposed on the outer periphery of the support frame 2. The insulation layers 5 are made of polyethylene, which has a low thermal conductivity, thus maintaining the internal temperature of the optical instrument enclosure and preventing changes in external temperature from affecting the internal temperature. A level is installed on the top surface of the enclosure, allowing direct observation of whether the entire optical instrument is in a horizontal and stable state.

[0032] A base plate 1 is installed inside the box; an optical element 3 is mounted on the base plate 1. The specific details of the optical element 3 are determined according to the type of optical instrument.

[0033] Temperature control plates 4 are installed on the inner walls of the enclosure. Copper pipes are embedded within the temperature control plates 4, and these pipes are connected to an external temperature-controlled water circulator 7. The temperature-controlled water circulator 7 supplies water, which flows through the pipes, and by changing the temperature of the water flow, maintains the internal temperature of the optical instrument enclosure. At least two temperature sensors 6 are installed inside the enclosure. These sensors monitor the internal temperature of the optical instrument enclosure and feed the monitoring data back to the controller, which then adjusts the water supply temperature of the temperature-controlled water circulator 7. The temperature-controlled water circulator 7 is equipped with a heating device and a cooling device; the heating device can use a heating wire, and the cooling device can use a Peltier cooling chip. The temperature-controlled water circulator 7 controls the internal temperature of the optical instrument enclosure by adjusting the water temperature through heating or cooling, based on the real-time internal temperature feedback from the temperature sensors 6.

[0034] like Figure 2 As shown, a circulating fan 8 is installed inside the enclosure; a filter element 9 is installed at the inlet of the circulating fan 8, and the outlet of the circulating fan 8 is connected to a circulating air duct 11, the other end of which is an air outlet; a particle sensor 10 is installed at the front end of the filter element 9. The circulating fan 8 enables air circulation inside the optical instrument enclosure. The filter element 9 is equipped with a two-stage filtration layer. Polluted air is drawn in by the circulating fan 8, filtered twice, and then clean air is output, thereby purifying the air inside the optical instrument enclosure. The particle sensor 10 can detect the cleanliness of the air inside the optical instrument, allowing the controller to adjust the power of the circulating fan 8. Through the combination of the circulating fan 8 and the circulating air duct 11, the air inside the optical instrument enclosure is circulated. The airflow is guided to various locations inside the enclosure through the circulating air duct 11, achieving uniform temperature and humidity inside the optical instrument enclosure and preventing localized temperature and humidity differences.

[0035] like Figure 3As shown, a humidity sensor 13 is installed inside the enclosure to monitor the humidity inside the optical instrument enclosure. The humidity sensor 13 can be specifically installed on the housing of the dehumidifier 12. The dehumidifier 12 is installed inside the enclosure. The dehumidifier 12 can be a small compressor or a device that uses a Peltier cooling chip for dehumidification. To prevent the evaporation of condensed liquid water, a one-way valve 14 is installed at the condensate drain outlet of the dehumidifier 12. An external water pipe can be connected to the condensate drain outlet to discharge the condensate. The one-way valve 14 prevents condensate from flowing back into the optical instrument enclosure, preventing secondary evaporation and increased internal humidity. The dehumidifier 12 utilizes the principle of condensation; by lowering the temperature of the dehumidifier 12, the humid air inside the optical instrument enclosure is condensed from a gaseous state to a liquid state and discharged from the optical instrument enclosure, thereby reducing the humidity inside the optical instrument enclosure.

[0036] In this embodiment, the temperature sensor 6, the temperature-controlled water circulator 7, the circulating fan 8, the particle sensor 10, and the dehumidification device 12 are connected to the controller via signals. Each electronic control component is controlled by the controller, which can be installed inside the optical instrument case.

[0037] The temperature adaptive principle of this invention is as follows: When the internal temperature of the optical instrument housing monitored by the temperature sensor 6 meets the temperature threshold range, the temperature-controlled water circulator 7 only circulates the pipes embedded inside the temperature control board 4 without heating or cooling, achieving a stable temperature. The outer layer of the temperature control board 4 is wrapped with an insulation layer, which further prevents heat dissipation and reduces temperature fluctuations. When the temperature sensor 6 detects that the internal temperature of the optical instrument housing is below the temperature threshold range, the heating device inside the temperature-controlled water circulator 7 heats the water supply, thereby increasing the temperature of the temperature control board 4. When the temperature reaches the temperature threshold range, the heating device operates at low power, achieving a stable temperature. When the internal temperature of the optical instrument housing monitored by the temperature sensor 6 is above the temperature threshold range, the cooling device inside the temperature-controlled water circulator 7 cools the water supply, thereby decreasing the temperature of the temperature control board 4. When the temperature reaches the temperature threshold range, the cooling device operates at low power, achieving a stable temperature.

[0038] When the temperature sensors at different locations inside the optical instrument housing detect that the internal temperature difference does not meet the temperature difference threshold, the circulating fan 8 continues to operate at low power; when the temperature sensors at different locations inside the optical instrument housing detect that the internal temperature difference meets the temperature difference threshold, the circulating fan 8 starts to operate normally, blowing the internal air through the circulating air duct 11 to various locations inside the optical instrument housing, thereby achieving the purpose of uniform temperature.

[0039] The cleanliness adaptive principle of this invention is as follows: The circulating fan 8 blows air from inside the optical instrument towards the particle sensor 10, which monitors the air cleanliness inside the optical instrument housing. When the particle sensor 10 detects that the air cleanliness inside the optical instrument housing meets the usage requirements, the circulating fan continues to operate at low power. When the particle sensor 10 detects that the air cleanliness inside the optical instrument housing does not meet the usage requirements, the circulating fan 8 operates normally. The turbid, dirty air inside the optical instrument housing first passes through the particle sensor 10, which monitors the air cleanliness in real time. The turbid, dirty air then passes through the filter element 9, thus filtering the turbid, dirty air into clean air. Finally, the clean air is blown to various locations inside the optical instrument housing by the circulating fan 8 through the circulating air duct 11.

[0040] The humidity adaptive principle of this invention is as follows: The humidity sensor 13 monitors the air humidity inside the optical instrument case in real time. When the air humidity is less than or equal to the humidity threshold, the dehumidifier 12 does not operate and remains in standby mode. When the air humidity is higher than the humidity threshold, the dehumidifier 12 starts operating and uses the condensation principle to condense the humid air inside the optical instrument case from a gaseous state to a liquid state, and then discharges it from the inside of the optical instrument case through an external water pipe, thereby reducing the humidity inside the optical instrument case.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions for some or all of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
