Description

Technical Field

[0001] This utility model specifically relates to a constant temperature box for bacterial culture, belonging to the field of microbial culture technology. Background Technology

[0002] Bacterial culture is a technique that uses artificial methods to grow and reproduce bacteria. Bacteria are widely distributed in nature, in large numbers and of many kinds. They can benefit mankind or cause disease. Most bacteria can be cultured artificially, that is, inoculated onto a culture medium to allow them to grow and reproduce. At present, the incubators used for bacterial culture on the market cannot meet the requirements of humidity and light simulation, and the temperature is constant and singular, making it impossible to culture petri dishes with various temperature requirements, and it is also impossible to control environmental variables in a timely manner. Chinese patent publication (patent number: CN219930115U) discloses a constant temperature chamber for bacterial culture, including an outer chamber, a base, and an inner chamber. A side plate is bolted to one side of the outer chamber, and a glass door is movably connected to the front of the outer chamber. There are three glass doors arranged side by side, and each glass door has a glass door handle. A door is located on one side of each glass door handle. The bottom of the outer chamber has a base, and the bottom surface of the outer chamber and the top surface of the base are attached to each other. The side of the base has heat dissipation grooves, and the bottom surface of the base has four casters. A controller is located on the front of the outer chamber. The inner chamber adopts a three-layer design, with each layer equipped with a light, a misting humidification device, and an air inlet. This enables the culture of bacteria in three different environments. The controller monitors and controls the environmental variables of each layer in real time to achieve high-quality bacterial culture. However, when the glass door of this invention is opened, the incubator is directly exposed to the external environment, and outside air can directly enter the space and may spread to other layers through shared air ducts and water sources. Frequent opening and closing of the door greatly increases the overall risk of contamination. Furthermore, the device does not mention any active cooling device, making it difficult to achieve precise independent temperature control. Utility Model Content

[0027] Working principle: When the operator needs to access a certain layer of the cultivation space, they pull the corresponding sealing plate 107 outward by pulling the handle 109. The sealing plate 107 is fixed on the sliding plate 201, and the sliding plate 201 slides out along the track at the top of the support bar 102 through the through groove 206 on it. The take-up body 203 in the take-up base 202 fixed on the sealing plate 107 will release the pull wire 205 as the sealing plate 107 moves outward. The pull wire 205 passes around the pulley in the pulley bracket 204 fixed at the top of the support bar 102 of that layer, and finally connects to the opening and closing plate 208 at the bottom of the partition plate 103 of that layer. The opening and closing plate 208 is hinged to the hinge seat 207 of the partition plate 103 by a torsion spring. Under normal conditions, it is kept in place by the action of the torsion spring. The device remains open. However, when the pull cord 205 is released by the take-up device, the opening and closing plate 208 quickly rotates downwards and closes under the action of the pull cord 205, tightly sealing the space between the current operating layer and the external space. Thus, the opening and closing plate 208 closes simultaneously with the opening of the sealing plate 107, ensuring that even if the sealing plate 107 is opened, unfiltered air and potential pollutants entering from the outside are strictly confined within the current sliding plate 201 and cannot spread through the shared air duct or water channel, significantly reducing the risk of cross-contamination. After the operation is completed, the operator pushes the sealing plate 107 inwards. At this time, the sliding plate 201 moves inwards along the track of the support bar 102, driving the take-up device base 202 fixed thereon to move towards the constant direction. The incubator moves internally, and the opening and closing plate 208 resets under the action of the torsion spring. After resetting, the take-up coil body 203 automatically winds the pull wire 205. The operator can initially observe the culture status through the observation window 108 integrated on the sealing plate 107 without opening the inner door, further reducing exposure. The incubator body 101 achieves precise temperature control through the integrated cooling host 116 and the layered independent heaters 106. The cooling host 116 is installed in the equipment box 113, and the generated cold air is delivered to the cold air outlets 121 opened on the inner side walls of each layer through independent air ducts. At the same time, each partition plate 103 is equipped with an independent heater 106 and a temperature sensor 120 at its bottom, and receives the temperature sensor 120 from each layer through the control panel 111. The system uses real-time data from 20 to determine whether to activate the cooling unit 116 to output cold air or to activate the blower 118 and heating wire 119 in the heater 106 of that layer for heating, so that the two work together to meet the specific needs of different bacterial species. Humidity control is achieved by the atomizing humidifier 114 in the equipment box 113 and the top water tank 112 working together. The water mist generated by the atomizing humidifier 114 is transported through pipes to the atomizing nozzles 105 at the bottom of the partition plates 103 of each layer and sprayed out. Each layer is also equipped with lighting 104 to provide necessary illumination. The backup battery 115 ensures that the critical system can operate briefly in the event of a power outage. The heat dissipation holes 117 on the side of the equipment box 113 are used to dissipate the heat generated by the cooling unit 116 and other equipment to maintain system stability.
