[0001] This utility model relates to the field of experimental equipment technology, and in particular to a glove box with a temperature control structure. Background Technology

[0002] Glove boxes, widely used in scientific research, chemical engineering, and electronics, provide operators with a safe, clean, and isolated operating environment, playing an indispensable role in handling sensitive materials and conducting oxygen- and water-free experiments. However, in the production of gallium-based alloy materials and for other applications, factors both inside and outside the glove box can interfere with the experimental materials and the operational process. Temperature control is imprecise, fluctuating significantly and unstablely, making it difficult to guarantee the accuracy and reliability of experimental results.

[0003] When using existing technical solutions, the temperature control components of some glove boxes are not arranged reasonably, resulting in uneven temperature distribution inside the box. There is a significant temperature difference between the area near the temperature control device and the area far away from the device, which makes it difficult to meet the experimental requirements for consistent temperature conditions when the experimental materials are placed in different locations.

[0004] To address the above problems, this utility model provides a glove box with a temperature control structure. Utility Model Content

[0011] Furthermore, the heating assembly includes a protective frame fixedly connected to the top of the bottom support plate, a heating tube fixedly connected inside the protective frame, and a dustproof and heat-insulating mesh threadedly connected to the top of the protective frame.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1.

[0027] Please see Figure 1-7 This utility model provides a technical solution: a glove box with a temperature control structure, including a box body 1, a temperature control mechanism 2 and a sealing connection mechanism 3. The temperature control mechanism 2 is fixedly connected to the inside of the sealing connection mechanism 3. The temperature control mechanism 2 includes a bottom support plate 21 fixedly connected to the bottom of the box body 1 by a thread, and a sealing groove 22 is fixedly connected to the top of the bottom support plate 21.

[0028] The specific settings and functions of its temperature control mechanism 2 and sealing connection mechanism 3 will be explained below.

[0029] In this embodiment: the temperature control mechanism 2 includes a sealing gasket 23 and a temperature sensor 24. The sealing gasket 23 is snapped into the inside of the sealing groove 22, and the temperature sensor 24 is fixedly connected to the inner wall of the housing 1.

[0030] Temperature sensor 24 is fixedly connected to the left and right sides of housing 1. Connecting frame 25 is fixedly connected to the edges of the left and right sides of housing 1. Servo motor 26 is fixedly connected inside the connecting frame 25. Connecting disk 27 is fixedly connected to the output end of servo motor 26. A guide fan 28 is threadedly connected to the outer surface of connecting disk 27. Bolt 29 is threadedly connected to both sides of guide fan 28. Guide fan 28 is threadedly connected to the outer surface of connecting disk 27 through bolt 29.

[0031] The effects achieved by the above components are as follows: the sealing gasket 23 is made of silicone rubber material that is resistant to high and low temperatures and has good elasticity. It fits tightly with the sealing groove 22 and can form an effective sealing barrier at the bottom of the box 1, greatly reducing the loss of heat or cold through the bottom of the box 1, laying the foundation for creating a stable temperature environment inside the glove box. The guide fan 28 can efficiently promote the air flow inside the box during rotation, promote the circulation and convection of hot and cold air, thereby effectively avoiding local overheating or underheating inside the box and ensuring uniform temperature distribution inside the box.

[0032] Specifically, the air guide fan 28 is fixedly connected to the inside of the housing 1. The air guide fan 28 is symmetrically arranged at the four corners on the left and right sides of the housing 1. A sealing rubber ring 210 is snapped into the gap between the temperature sensor 24 and the housing 1.

[0033] The effects achieved by the above components are as follows: the air guide fan 28 is symmetrically distributed on the four corners of the left and right sides of the box 1, which can push the air flow from multiple directions to form a more uniform and efficient air circulation path, further enhancing the temperature uniformity effect inside the box; the sealing rubber ring 210 is filled in the gap between the temperature sensor 24 and the box 1, which can effectively prevent gas leakage inside the box and prevent outside air from entering and interfering with the temperature environment inside the box.

[0034] Specifically, the temperature control mechanism 2 includes a cooling assembly 211 fixedly connected to the rear side wall of the housing 1, and a heating assembly 212 fixedly connected to the top of the bottom support plate 21. The cooling assembly 211 includes a fixing frame 2111 fixedly connected to the rear side wall of the housing 1. Cooling plates 2112 are fixedly connected to the inner wall of the fixing frame 2111. The cooling plates 2112 are evenly arranged at equal distances on the inner wall of the fixing frame 2111. Connecting wires 2113 are fixedly connected to the outer surface of adjacent cooling plates 2112.

[0035] The effects achieved by the above components are as follows: the fixed frame 2111 in the cooling assembly 211 provides a stable mounting base for the cooling element 2112. The cooling elements 2112, which are evenly spaced, adopt semiconductor cooling technology and are connected in series by connecting wires 2113. They can work together to quickly absorb heat inside the chamber. When the temperature inside the chamber is higher than the set value, the cooling element 2112 is activated to transfer heat to the outside of the chamber, achieving rapid cooling. The uniform layout ensures that all areas inside the chamber can be effectively cooled, avoiding local temperature differences.

[0036] Specifically, the heating assembly 212 includes a protective frame 2121 fixedly connected to the top of the bottom support plate 21, a heating tube 2122 fixedly connected inside the protective frame 2121, and a dustproof and heat-insulating mesh 2123 threadedly connected to the top of the protective frame 2121.

[0037] The effects achieved by the above components are as follows: the protective frame 2121 protects the heating tube 2122, preventing damage to the heating tube 2122 from collisions during the experiment. The heating tube 2122 has the characteristics of high heating efficiency and uniform heat dissipation, which can quickly increase the temperature inside the chamber. The dustproof and heat insulation net 2123 is installed on the top of the protective frame 2121, which can block dust from entering the heating component 212, ensuring the normal operation and service life of the heating tube 2122, and enabling the temperature inside the chamber to rise quickly and remain stable.

[0038] Specifically, the sealing connection mechanism 3 includes a double-layer shelf 31 fixedly connected to the top of the bottom support plate 21, and ventilation holes 32 are provided on both sides of the double-layer shelf 31.

[0039] The effects achieved by the above components are as follows: the double-layer shelf 31 has good corrosion resistance and strength, and can stably support experimental items. The ventilation holes 32 on both sides ensure the stability of the experimental items while not obstructing the air circulation inside the chamber, ensuring that the hot and cold airflow generated by the temperature control mechanism 2 can circulate smoothly inside the chamber, so that the temperature inside the chamber is evenly distributed and the temperature control effect is not affected by the presence of the shelf.

[0040] Specifically, a washer 33 is snapped into the front side of the sealing connection mechanism 3, a connecting fixing plate 34 is threaded onto the outer surface of the washer 33, and a glove 35 is fixedly connected to the outer surface of the connecting fixing plate 34.

[0041] The effects achieved by the above components are as follows: the gasket 33 and the connecting fixing plate 34 cooperate to form a good sealing structure on the front side of the chamber 1, preventing outside air from entering the chamber and ensuring the stability of the environment inside the chamber. The gloves 35 are fixed on the connecting fixing plate 34, which makes it convenient for operators to enter the chamber to carry out experimental operations without opening the chamber 1. This ensures that the environment inside the chamber is not disturbed by the outside world and meets the needs of experimental operations.

[0042] Specifically, fasteners 36 are threaded on both sides of the connecting fixing plate 34. Gloves 35 are threaded to the front of the box 1 through the fasteners 36. Gloves 35 and washers 33 are evenly distributed at four equal intervals on the front of the box 1. Washers 33 are snapped into the connection gap between the connecting fixing plate 34 and the front of the box 1. The sealing connection mechanism 3 includes a lighting lamp 37 fixedly connected to the inner top wall of the box 1.

[0043] The effects achieved by the above components are as follows: the fastener 36 can securely install the connecting fixing plate 34 and the glove 35 on the front side of the chamber 1, ensuring the stability of the sealing structure; the glove 35 and the washer 33 are evenly distributed in four equal parts on the front side of the chamber 1, further enhancing the sealing effect and ensuring the stability of the environment inside the chamber; the lighting lamp 37 fixed on the top wall inside the chamber 1 can provide sufficient light, so that even in a dimly lit environment, the operator can clearly observe the experimental situation inside the chamber, facilitating precise operation.

[0044] Working principle: When the glove box is started, the temperature sensor 24 monitors the temperature of different areas inside the box in real time and transmits the data to the external control system. The control system compares the received temperature data with the preset temperature value.

[0045] If the temperature inside the chamber is higher than the preset value, the control system issues a command to start the cooling component 211. The cooling chip 2112 starts working, absorbing the heat inside the chamber through semiconductor cooling technology, and working together through the connecting wire 2113 to quickly reduce the temperature inside the chamber. At the same time, the servo motor 26 drives the guide fan 28 to rotate, promoting the air circulation inside the chamber, so that the cooling energy generated by the cooling chip 2112 is evenly diffused to all corners of the chamber 1, accelerating the cooling speed and ensuring uniform temperature.

[0046] If the temperature inside the chamber is lower than the preset value, the control system will activate the heating component 212. The heating tube 2122 heats up quickly after being powered on, and the finned design efficiently dissipates heat to raise the temperature inside the chamber. The dustproof and heat insulation net 2123 effectively reduces heat loss and improves heating efficiency. At this time, the guide fan 28 also operates under the drive of the servo motor 26, which promotes the circulation of hot air inside the chamber and achieves a uniform temperature rise.

[0047] Throughout the temperature control process, sealing components such as sealing gasket 23, sealing rubber ring 210, and gasket 33 work together to effectively prevent heat or cold loss from the chamber and the entry of outside air, maintaining a stable temperature environment inside the chamber. When operators perform experiments inside the chamber using gloves 35, the double-layer shelf 31 stably supports the experimental items, the vent strip 32 ensures that air circulation is not affected, and the lighting 37 provides a clear operating view. All components work together to ensure the efficient and stable operation of the glove box.
