Description

Technical Field

[0001] This utility model relates to the field of dehumidifier technology, specifically to a micro-infrared spectrometer-based intelligent dehumidifier. Background Technology

[0002] A micro-infrared spectrometer is a high-precision instrument that uses the principle of infrared light interacting with matter and combines microscopic techniques to analyze the composition and structure of samples in tiny areas. Its core optical components (such as infrared light sources, interferometers, and detectors) and precision electronic components have extremely demanding requirements for the storage environment. Temperature and humidity must be strictly controlled, dust intrusion must be prevented, and physical shocks and vibrations must be avoided to ensure the long-term stability, measurement accuracy, and service life of the instrument. Therefore, when the instrument is not in operation, it usually needs to be stored in a dedicated dehumidifying box to provide a relatively stable, clean, and low-humidity protective environment.

[0003] However, existing traditional desiccant boxes for storing micro-infrared spectrometers have significant shortcomings. Their heavy lids rely on manual opening and closing, which is laborious and prone to impacting the instrument due to sudden drops or misalignments; their environmental control capabilities are weak, making it difficult to maintain the required constant low temperature and low humidity environment, increasing the risk of moisture oxidation of optical components; the box's sealing performance is poor, making it susceptible to the intrusion of external moisture and dust; and they generally lack intelligent monitoring and alarm functions, making it impossible to detect anomalies in real time or achieve remote management, posing safety hazards when unattended. Therefore, an intelligent desiccant box for micro-infrared spectrometers is needed to address these shortcomings. Utility Model Content

[0004] Traditional moisture-proof boxes for micro-infrared spectrometers suffer from problems such as laborious operation, weak environmental control, poor sealing, and lack of intelligent monitoring, which seriously affect the safety and long-term reliability of instrument storage. The purpose of this utility model is to solve the problems existing in the prior art and provide an intelligent moisture-proof box for micro-infrared spectrometers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a smart dehumidifying box for a micro-infrared spectrometer, comprising:

[0006] The box has an opening;

[0007] A lid for closing the opening of the box;

[0008] An automatic opening and closing system is connected between the box body and the box cover, and is used to drive the box cover to automatically open and close relative to the box body;

[0009] An intelligent environmental control system is installed inside the enclosure to monitor and adjust the temperature and humidity inside the enclosure in real time.

[0010] The main control unit is electrically connected to the automatic opening and closing system and the intelligent environmental control system, and is used to receive instructions and control the operation of each system.

[0011] Furthermore, the automatic opening and closing system includes:

[0012] At least one electro-hydraulic rod;

[0013] A drive unit is used to provide power to the electro-hydraulic rod;

[0014] The control module, electrically connected to the main control unit, is used to receive instructions from the main control unit and control the start, stop, and steering of the drive device;

[0015] A limit switch is used to detect the extreme position of the lid and send a signal to the control module when the lid reaches a preset open or closed position to stop the operation of the drive device.

[0016] Furthermore, it also includes a display input module, which is electrically connected to the main control unit and is used to send commands to the main control unit to control the opening or closing of the box cover. It is also used to display real-time temperature and humidity data inside the box, the operating status of the equipment, and to allow users to set parameters.

The main control unit controls the start and stop of the dehumidification module and / or heating module based on the data collected by the temperature and humidity sensor to maintain the environment inside the chamber within a preset temperature and humidity range.

[0022] Furthermore, the dehumidification module is a semiconductor condensation dehumidification device or a molecular sieve dehumidification device.

[0023] Furthermore, it also includes a remote monitoring and alarm system, which includes:

[0024] A communication module, electrically connected to the main control unit, is used to send the status information inside the box to an external terminal and receive control commands from the external terminal.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] like Figure 1-4As shown, the intelligent dehumidifying box of this application includes a box body 1 and a lid 2. To facilitate the handling of precision instruments such as micro-infrared spectrometers, the opening of the box body 1 is designed to be inclined with a lower front and higher back, that is, the height of the front end of the opening is lower than the height of the rear end, forming an inclined surface that facilitates operation. In accordance with the shape of this opening, the outline of the lid 2 is trapezoidal, which provides a larger operating space and a better viewing angle at the front end of the opening when the user puts or takes out the spectrometer into or out of the box body 1, effectively avoiding collisions with the edge of the box body 1, and greatly improving the convenience and safety of operation. A high-elasticity pad 11 is installed at the bottom of the box body 1. The pad 11 is integrally molded from a polymer material (such as silicone or polyurethane rubber) with excellent resilience, and its surface has a textured structure to enhance friction (such as grid-like protrusions or anti-slip textures). When the spectrometer is placed inside the box body 1, the pad 11 achieves double protection through the following mechanism:

[0041] Elastic buffering and shock absorption: The pad 11 undergoes controllable deformation under the gravity of the spectrometer, forming a flexible support surface, which effectively absorbs external vibration and impact energy (such as handling or environmental vibration) and avoids damage to instrument components caused by rigid contact.

[0042] Friction-based anti-slip positioning: The surface texture of the pad 11 significantly increases the static friction coefficient with the bottom of the spectrometer. Combined with the adsorption effect generated by elastic deformation, it ensures that the instrument maintains a stable posture inside the housing 1, avoiding displacement or shaking caused by tilting, collision or inertial motion. It is especially suitable for long-term storage protection of precision optical components.

[0043] To ensure the stability of the internal environment of the cabinet 1 and prevent the intrusion of external moisture and dust, this application sets up an efficient sealing structure between the cabinet 1 and the lid 2. Specifically, an annular elastic sealing strip 9, made of materials such as silicone or rubber, is installed at the edge of the opening of the cabinet 1. Correspondingly, a sealing groove 10 matching the shape and position of the sealing strip 9 is constructed on the bottom side of the lid 2, that is, the surface in contact with the opening of the cabinet 1. When the lid 2 is fully closed under the drive of the automatic opening and closing system, the sealing strip 9 is tightly pressed into the sealing groove 10, forming a reliable physical barrier. This design of the sealing strip 9 and the sealing groove 10 significantly improves the airtightness of the dehumidifier and provides a stable and clean storage environment for the internal precision instruments.

[0044] like Figure 1 and Figure 4 As shown, the automatic opening and closing system of this application includes at least one electric hydraulic rod 3, preferably two symmetrically installed on both sides of the box body 1 and hinged to the box cover 2. The two hydraulic rods operate synchronously to ensure that the box cover 2 is subjected to uniform force and moves smoothly during opening and closing, and to avoid the box cover 2 tilting or jamming due to uneven force on one side.

[0045] Each electro-hydraulic lever 3 consists of an electric drive unit and a hydraulic actuator unit. The electric drive unit uses a DC motor as a power source, driving a hydraulic pump through gear transmission or a worm gear structure to convert electrical energy into mechanical energy, providing power input to the hydraulic system. The hydraulic actuator unit includes a hydraulic cylinder, a piston rod, and a sealing structure. The hydraulic pump pressurizes hydraulic oil (or other hydraulic medium) and sends it to the hydraulic cylinder, pushing the piston rod to perform linear extension and retraction, thereby driving the opening and closing of the cover 2. The hydraulic cylinder integrates a buffer device; when the piston rod approaches the fully open or fully closed position, the hydraulic oil slowly flows back through a throttle valve, automatically decelerating the piston rod and effectively preventing mechanical impact.

[0046] The main control unit sends commands to the DC motor via the control module to adjust the motor's speed and direction, thereby controlling the output pressure and flow of the hydraulic pump. This, in turn, precisely controls the extension and retraction speed and direction of the hydraulic rod. The system also includes Hall effect sensors or limit switches to detect the opening and closing limits of the cover 2 in real time. When the sensor detects that the cover 2 has reached the preset position, the main control unit immediately stops the motor and cuts off the oil supply to the hydraulic pump, ensuring the system's safety and reliability.

[0047] The intelligent environmental control system includes a temperature and humidity sensor 4, a dehumidification module 5, a heating module 6, and a main control unit. The temperature and humidity sensor 4 collects environmental data inside the chamber in real time. The main control unit automatically controls the start and stop of the dehumidification module 5 and / or the heating module 6 according to the preset temperature and humidity range (e.g., temperature 20±2℃, humidity ≤40%RH) to maintain a stable environment inside the chamber.

[0048] The dehumidification module 5 is a semiconductor condensation dehumidification device or a molecular sieve dehumidification device, preferably with a square structure for easy installation and replacement. The heating module 6 is a PTC heating element or heating wire, which is evenly distributed on the inner wall of the box 1 to avoid local overheating.

[0049] This application also includes a communication module and an alarm module 8. The communication module supports Wi-Fi, Bluetooth or cellular networks and can upload environmental data and equipment status inside the box to the cloud or the user's mobile APP to realize remote monitoring and alarm. The alarm module 8 will issue an audible and visual alarm when there is abnormal temperature and humidity, equipment failure or the box cover 2 is not completely closed, and send alarm information to the user through the communication module.

[0050] The enclosure 1 is equipped with an LCD touch screen 7, which is electrically connected to the main control unit. It is used to display the real-time temperature and humidity inside the enclosure, the equipment operating status, historical data curves, and allows users to set parameters, switch modes, and perform manual control.

[0051] The enclosure 1 is made of stainless steel or aluminum alloy, and the inner wall is filled with insulation material to ensure good sealing and heat insulation. A sealing strip 9 is provided between the lid 2 and the enclosure 1 to prevent external moisture from entering.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
