Description

Technical Field

[0001] This utility model relates to the field of laboratory equipment technology, and in particular to a temperature and humidity regulating laboratory specimen preservation device. Background Technology

[0002] In the laboratory, specimens are important research and teaching materials, and their preservation status directly affects the accuracy and reliability of research results. Temperature and humidity are crucial environmental factors during specimen preservation. Too high or too low a temperature may cause changes in the chemical composition of the specimen, microbial growth, or problems such as specimen drying, cracking, and brittleness. Too high a humidity can easily cause mold growth and specimen rot, while too low a humidity will cause the specimen to dehydrate and deform.

[0003] For example, Chinese patent CN215246564U discloses a specimen storage device for laboratory testing, including a cabinet and a cabinet door. The cabinet door is hinged to one side of the cabinet. A rotating rod runs through the two sides of the cabinet. Two rotating rings are fitted on the outer wall of the rotating rod. A rotating shaft is set between the two rotating rings. A bearing sleeve is fitted on the outer wall of the rotating shaft. A support rod is welded to one side of the outer wall of the bearing sleeve. A specimen tray is welded to the end of the support rod away from the bearing sleeve. A groove is located on one side of the test tube hole. A fixing rod is welded to the outer wall of the rotating rod near the bearing sleeve. A round rod is welded to one end of the fixing rod. A handwheel is welded to one end of the rotating rod. An arc-shaped groove is opened on one side of the outer wall of the cabinet. A through hole is opened inside the arc-shaped groove. An instrument box is provided at the bottom of the cabinet.

[0004] Currently, common specimen preservation methods mainly rely on simple temperature and humidity control equipment, which cannot precisely control parameters such as temperature, humidity, and light in the preservation environment. Excessively high or low temperatures, or excessive or insufficient humidity, can lead to problems such as specimen deterioration, mold growth, and cracking, affecting the quality and research value of the specimens.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-4As shown, this utility model provides a temperature and humidity regulated laboratory specimen preservation device, including a cabinet 1, with cabinet doors 2 rotatably mounted on both sides of the cabinet 1, and also including a temperature sensor 11, a humidity sensor 12, a small compressor 13, an ultrasonic humidifier 14, a condenser dehumidifier 15, a heater 9, and a controller 8 for intelligent control. Multiple LED light strips 5 are evenly fixedly connected to the inner side of the cabinet doors 2, and a light sensor 4 is fixedly connected to the outer side of the cabinet 1. A stainless steel inner layer 20 is fixedly connected to the inner wall of the cabinet 1. The cabinet 1 and the stainless steel inner layer... The space between the stainless steel inner layer 20 is filled with heat insulation filler 21. Multiple fixing plates 16 are symmetrically and evenly fixed to the inner side wall of the stainless steel inner layer 20, and a partition 17 is slidably installed between every two fixing plates 16. A heating wire 19 is fixedly connected to the inner side of the stainless steel inner layer 20. An ultrasonic humidifier 14 and a condenser dehumidifier 15 are respectively fixed to the bottom of the cabinet 1. A small compressor 13 and a controller 8 are respectively fixed to both sides of the cabinet 1. A temperature sensor 11 and a humidity sensor 12 are symmetrically fixed to one side of the bottom of the cabinet 1. A light sensor 4 is signal connected to the controller 8.

[0023] The specific setup and function of this embodiment are described below: The maintenance device mainly consists of a cabinet 1, two cabinet doors 2, a light sensor 4, multiple LED light strips 5, a temperature sensor 11, a humidity sensor 12, a small compressor 13, an ultrasonic humidifier 14, a condenser dehumidifier 15, a heater 9, and a controller 8 for intelligent control. The cabinet 1 is a sealed structure, with an inner layer 20 made of stainless steel. Insulation filler 21 is placed between the two layers to effectively reduce heat exchange and lower the energy consumption of the temperature and humidity control module. The temperature and humidity control module adjusts according to actual conditions... The device operates precisely to avoid temperature and humidity deviations, thus avoiding energy waste and meeting energy conservation and environmental protection requirements. Users can set the standard temperature and humidity range, as well as appropriate light intensity and spectrum, through the display panel of controller 8 according to the maintenance needs of different specimens. The display panel of controller 8 shows the temperature, humidity, and light intensity data inside cabinet 1 in real time, which users can view at any time for further optimization and adjustment of the maintenance device. Temperature sensor 11 and humidity sensor 12 can collect temperature and humidity data inside the maintenance cabinet 1 in real time and transmit the data to controller 8. The intelligent control within controller 8... The control module compares the received temperature and humidity data with preset standard ranges. If the temperature inside the cabinet is detected to be lower than the preset range, the controller 8 controls the heater 9 to start the heating wire 19, thereby heating the air in the cabinet 1. When the temperature rises to the preset range, the controller 8 controls the heater 9 and heating wire 19 to stop working. If the temperature inside the cabinet 1 is detected to be higher than the preset range, the controller 8 starts the small compressor 13 cooling system to lower the temperature inside the cabinet 1 until the temperature returns to the preset range. When the humidity inside the cabinet is lower than the preset range, the controller 8 controls the ultrasonic humidifier 14 to work, humidifying the air inside the cabinet. Water mist is sprayed inside the chamber 1 to increase air humidity. When the humidity reaches the preset range, the controller 8 controls the ultrasonic humidifier 14 to stop working. If the humidity inside the chamber is higher than the preset range, the controller 8 starts the condenser dehumidifier 15 to reduce the humidity until the humidity returns to the preset range. The light sensor 4 monitors the light intensity inside the chamber in real time. The LED light strip 5 is connected to the controller 8 through an intelligent dimming circuit. The light sensor 4 feeds back the detected light data to the controller 8. When the actual light intensity does not match the set value, the controller 8 automatically adjusts the brightness of the LED light strip 5 to provide a suitable lighting environment for the specimen.

[0024] By arranging temperature sensor 11, humidity sensor 12, and light sensor 4 inside the preservation cabinet 1, comprehensive and accurate temperature, humidity, and light intensity data of the area inside the cabinet 1 can be collected. Combined with the intelligent control module, temperature and humidity adjustment module, and light adjustment module, precise temperature and humidity regulation can be achieved to ensure that the specimen is always in a suitable preservation environment. The intelligent control module of the controller 8 automatically controls the temperature and humidity adjustment module according to the preset temperature and humidity standard range, eliminating the need for frequent manual operation, improving the efficiency and stability of specimen preservation, and reducing the impact of human factors on the specimen preservation environment.

[0025] Example 2: Figures 1-3 As shown, a label plate 18 is fixedly connected to one end of the partition 17, multiple glass windows 10 are evenly arranged on one side of the cabinet 1, the heater 9 is fixedly installed on the rear side of the cabinet 1, a base 6 is fixedly installed at the bottom of the cabinet 1, a protective frame 7 is fixedly installed on the outer side of the bottom of the cabinet 1, multiple LED light strips 5 are respectively arranged between adjacent fixed plates 16, multiple glass windows 10 are respectively arranged between adjacent fixed plates 16, and a sealing strip 3 is fixedly connected to the inner edge of the cabinet door 2.

[0026] The overall effect of this embodiment is that the cabinet 1 has multiple glass windows 10 on its side, and the glass windows 10 are made of UV-resistant glass, which facilitates the observation of specimens while preventing UV damage to the specimens. The sealing strip 3 between the cabinet 1 and the cabinet door 2 can ensure the airtightness of the cabinet 1. By symmetrically arranging multiple fixed plates 16 inside the cabinet 1, the partition 17 can be slidably installed between the left and right fixed plates 16 from front to back. The multiple partitions 17 can be adjusted in position according to the size of different specimens, which improves the applicability of the device. Experimenters can place different specimens on different partitions 17, and write the specimen name on the label plate 18 in front of the partition 17, which makes it convenient for experimenters to quickly identify and find the specimens.

[0027] The device is used and works as follows: The space between the cabinet 1 and the stainless steel inner layer 20 is filled with heat insulation filler 21, which can effectively reduce heat exchange and avoid energy waste. The multiple partitions 17 can be adjusted in position according to the size of different specimens to improve the applicability of the device. Experimenters can place different specimens on different partitions 17 and write the specimen name on the label plate 18 in front of the partition 17 to facilitate quick identification and retrieval of specimens.

[0028] Users can set the standard temperature and humidity range, as well as appropriate light intensity and spectrum, through the display panel of controller 8 according to the preservation needs of different specimens. Temperature sensor 11, humidity sensor 12, and light sensor 4 can collect temperature, humidity, and light intensity data inside the preservation cabinet 1 in real time and transmit the data to controller 8. The intelligent control module inside controller 8 compares and analyzes the received temperature, humidity, and light intensity data with the preset standard range, thereby controlling heater 9, small compressor 13, ultrasonic humidifier 14, condenser dehumidifier 15, and LED light strip 5 to adjust the temperature, humidity, and light intensity inside cabinet 1, providing a suitable temperature, humidity, and light environment for the specimens. Through multiple sensors, temperature, humidity, and light intensity data of the area inside cabinet 1 can be collected comprehensively and accurately. Combined with the intelligent control module, temperature and humidity adjustment module, and light adjustment module, precise adjustment of temperature and humidity can be achieved to ensure that the specimens are always in a suitable preservation environment without frequent manual operation, thus improving the efficiency and stability of specimen preservation.
