Description

Technical Field

[0001] This utility model relates to the field of temperature control device technology, specifically to a dynamic temperature control device. Background Technology

[0002] In the field of temperature control, especially in scenarios involving the shaking culture or preservation of laboratory reagents, dynamic temperature regulation and environmental sterility are key factors affecting experimental results. In existing technologies, reagent shaking devices typically employ independent heating or cooling modules, controlling the temperature of the reagent container via external devices. However, the heating modules in existing reagent shaking devices can only locally heat the reagent container, such as only heating the bottom, leading to uneven temperature distribution within the container and affecting the reagent reaction effect. The cooling function relies on an external circulation system, which is not only slow in response but also difficult to achieve dynamic temperature regulation, failing to meet the needs of some experiments sensitive to temperature changes.

[0003] Meanwhile, the sterilization and disinfection process also has shortcomings. Traditional methods struggle to achieve continuous and comprehensive sterilization during reagent shaking, failing to effectively eliminate microorganisms within the container and its surrounding environment, easily leading to reagent contamination and affecting the accuracy of experimental results. Therefore, it is essential to develop a reagent shaking device that can achieve precise dynamic temperature control and possesses excellent sterilization capabilities. Utility Model Content

The technical solution of this utility model will be clearly and completely described below in conjunction with embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.

[0027] Example 1: In the practical application of the dynamic temperature control device, the shaker bracket 1 serves as the overall support structure. The base plate 11 is placed horizontally, the control box 12 is fixed to the top right side of the base plate 11 with bolts, and the support plate 13 is fixed to the top left side of the base plate 11. A wrap-around reagent rack 2 is installed inside the shaker bracket 1. The rotating shaft 22 is horizontally positioned, with its right end fixedly connected to the output shaft of the shaker motor in the upper part of the control box 12 via a coupling, and its left end rotatably connected to the inner side wall of the support plate 13 via a shaft seat, ensuring stable rotation of the rotating shaft 22. A fixing plate 21 is fixed to the left and right sides of the outer ring of the rotating shaft 22, and a reagent rack 27 is fixed between the fixing plates 21 for placing reagent tubes to be shaken. The lower U-shaped frame 25 and the upper U-shaped frame 28 are hinged to the fixing plate 21 at their rear upper and lower positions for easy opening and closing. A through hole is opened at the bottom of the lower U-shaped frame 25, and a square frame 241 is embedded and fixed in the through hole. A servo fan 242 is installed on the upper layer of the inner cavity of the square frame 241, and an electric heating wire 243 is installed on the lower layer. A notch is opened on the top surface of the upper U-shaped frame 28, and a TEC semiconductor cooling chip 291 is embedded and fixed in the notch. A heat dissipation fan 292 is installed on its cooling end face, and a cold air delivery fan 293 is installed on its heating end face.

[0028] Two temperature sensors 23 and three ultraviolet lamps 210 are respectively installed on the inner sidewalls of the upper U-shaped frame 28 and the lower U-shaped frame 25. The temperature sensors 23 are used to monitor the internal temperature in real time, and the ultraviolet lamps 210 are used to sterilize and disinfect the internal environment. Two latches 26 are installed on the front sidewalls of the upper U-shaped frame 28 and the lower U-shaped frame 25, and a sealing gasket is placed between the contact end faces to ensure a tight seal when closed. A controller is installed in the inner cavity of the control box 12, and a control panel is installed on the front sidewall. When heating is required, the servo fan 242 and the electric heating wire 243 are activated through the control panel. The servo fan 242 delivers the heat generated by the electric heating wire 243 to the inner cavity of the upper U-shaped frame 28 and the lower U-shaped frame 25 to achieve the heating function.

[0029] Example 2: In another usage scenario, the structure of the dynamic temperature control device is basically the same as in Example 1. The installation methods of the base plate 11, control box 12, and support plate 13 of the shaker bracket 1 remain unchanged. In the wrap-around reagent rack 2, the connection method of the rotating shaft 22 is the same, and the hinge methods of the fixing plate 21, reagent rack 27, lower U-shaped frame 25, and upper U-shaped frame 28 are also the same. The bottom of the lower U-shaped frame 25 is inlaid with a fixed square frame 241, and a servo fan 242 and an electric heating wire 243 are installed inside. The top of the upper U-shaped frame 28 is inlaid with a fixed TEC semiconductor cooling chip 291, and a cooling fan 292 and a cold air delivery fan 293 are installed. Four temperature sensors 23 and six ultraviolet lamps 210 are installed on the inner sidewalls of the upper U-shaped frame 28 and the lower U-shaped frame 25, and a buckle 26 and a sealing gasket are installed on the front sidewall. When cooling is required, the cooling fan 292 and the cold air delivery fan 293 are started through the control panel. The cooling fan 292 mixes the low temperature generated by the cooling end face of the TEC semiconductor cooling chip 291 with air and delivers it to the interior of the lower U-shaped frame 25 and the upper U-shaped frame 28 for cooling; the cold air delivery fan 293 dissipates heat from the heating end face of the TEC semiconductor cooling chip 291 to ensure that the cooling end face remains at a low temperature, thereby achieving the cooling function.

[0030] Example 3: When the dynamic temperature control device is used in a specific laboratory experiment, the shaker stand 1 is installed in a conventional manner, with the base plate 11 placed securely. The control box 12 and support plate 13 are fixed to the top two sides of the base plate 11, respectively. In the enclosed reagent rack 2, the connection between the rotating shaft 22 and the output shaft and bearing seat of the shaker motor ensures normal rotation. The lower U-shaped frame 25 and the upper U-shaped frame 28 are connected to the fixed plate 21 by hinges. The bottom of the lower U-shaped frame 25 is inlaid with a square frame 241 and a heating component 24 is installed. The top of the upper U-shaped frame 28 is inlaid with a TEC semiconductor cooling chip 291 and a cooling component 29 is installed. Three temperature sensors 23 and four ultraviolet lamps 210 are installed on the inner sidewalls of the upper U-shaped frame 28 and the lower U-shaped frame 25. The front sidewall is fitted with a buckle 26 and a sealing gasket. During the experiment, depending on the experimental requirements, the heating function can be activated via the control panel, using the servo fan 242 and electric heating wire 243 to heat the internal environment; alternatively, the cooling function can be activated, using the heat dissipation fan 292 and cold air delivery fan 293 to cool the internal environment. Simultaneously, the ultraviolet lamp 210 continuously operates to sterilize and disinfect the internal environment, ensuring a hygienic experimental environment.

[0031] Based on the above preferred technical solution, the workflow of this technical solution is described as follows:

[0032] The reagent tubes to be shaken are clamped and placed inside the reagent rack 27. Then, by operating the latches 26 on the front sidewalls of the upper U-shaped frame 28 and the lower U-shaped frame 25, the upper U-shaped frame 28 and the lower U-shaped frame 25 are closed. At this time, the sealing gasket between the contact surfaces of the two frames acts as a seal to prevent excessive exchange of internal air with the outside. The shaker motor in the upper layer of the control box 12 starts to work. Its output shaft drives the rotating shaft 22 to rotate through the coupling. The left end of the rotating shaft 22 rotates in the shaft seat on the inner sidewall of the support plate 13, thereby driving the reagent rack 27, which is fixed between the left and right fixing plates 21 on the outer ring of the rotating shaft 22, to shake, so that the reagents in the reagent tubes are fully mixed. When heating of the internal environment is required, the servo fan 242 and electric heating wire 243 in the heating assembly 24 are activated via the control panel on the front side wall of the control box 12. After the electric heating wire 243 is powered on, it generates heat, and the servo fan 242 starts to run, transporting the heat generated by the electric heating wire 243 into the inner cavity of the upper U-shaped frame 28 and the lower U-shaped frame 25, so that the internal temperature gradually rises. The temperature sensor 23 on the inner side wall of the upper U-shaped frame 28 and the lower U-shaped frame 25 monitors the internal temperature in real time and feeds back the temperature information to the controller in the inner cavity of the control box 12. When the temperature reaches the set value, the controller controls the servo fan 242 and electric heating wire 243 to stop working via the control panel.

[0033] When cooling of the internal environment is required, the cooling fan 292 and the cold air delivery fan 293 in the cooling assembly 29 are activated via the control panel. The TEC semiconductor cooling chip 291 begins to work, generating a low temperature at its cooling end. The cooling fan 292 mixes the low temperature generated at the cooling end with air and delivers it to the interior of the lower U-shaped frame 25 and the upper U-shaped frame 28 for cooling. Simultaneously, the heating end of the TEC semiconductor cooling chip 291 generates heat, and the cold air delivery fan 293 operates to dissipate heat from the heating end, ensuring that the cooling end remains at a low temperature. Temperature sensors 23 on the inner sidewalls of the upper U-shaped frame 28 and the lower U-shaped frame 25 monitor the internal temperature in real time. When the temperature reaches the set value, the controller stops the cooling fan 292 and the cold air delivery fan 293 via the control panel. Throughout the entire operation, the ultraviolet lamps 210 on the inner sidewalls of the upper U-shaped frame 28 and the lower U-shaped frame 25 continuously operate to sterilize and disinfect the internal environment, preventing bacterial growth that could affect reagent quality.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
