Description

Technical Field

[0001] This utility model belongs to the technical field of microbial detection and culture equipment, and specifically relates to a microbial incubator with a structure that isolates it from external air. Background Technology

[0002] Existing microbial incubators have several drawbacks in preventing outside air from entering the culture dishes, primarily in terms of air pollution and cross-contamination of microorganisms. When the culture dishes are opened, contaminants such as microorganisms and dust from the outside air may enter the culture medium, affecting experimental results and leading to impure cultures or false positives. Traditional incubators typically rely on gravity or simple sealing designs to slow the entry of outside air, but they cannot effectively prevent the direct intrusion of contaminants, especially when the incubator door is frequently opened or under unfavorable environmental conditions, where the risk is even more significant.

[0003] Conventional solutions to this problem include using a laminar flow hood in conjunction with aseptic techniques during operation, or installing high-efficiency filters in the incubator's ventilation system to block contamination. However, these methods also have significant drawbacks. While laminar flow hoods offer some protection, they are only used during operation and require rigorous training and adherence to operating procedures; otherwise, contamination can still be introduced. Therefore, we aim to design a novel microbial incubator to address this issue. Utility Model Content

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.

[0025] Please see Figures 1 to 5The present invention provides a technical solution: a microbial incubator 230 with an air-isolation structure, comprising: a base 100 and an incubation component 200, wherein the incubation component 200 is fixed on the upper side of the base 100, and the incubation component 200 includes an outer box 210, a sealing door 220, an incubator 230 and a unit box 240.

[0026] The outer box 210 has sealing doors 220 hinged to the front and rear sides respectively. An incubator 230 is installed in the middle of the outer box 210. Multiple evenly distributed unit boxes 240 are slidably installed on the front and rear sides of the incubator 230 respectively.

[0027] The incubator 230 is equipped with a seal 234, which includes an electric telescopic rod and a baffle.

[0028] Please see Figures 1 to 3 The incubator 230 has multiple mounting cavities 231 on the front and rear sides of its bottom, and a constant temperature cavity 232 on the upper side of the incubator 230. The bottom of the constant temperature cavity 232 extends downward to form multiple ventilation hole groups 233.

[0029] An electric telescopic rod is installed on the front side of the bottom of the constant temperature chamber 232. A baffle is fixed at the rear end of each electric telescopic rod. The width of the baffle is greater than the width of the ventilation hole group 233. The lower surface of the baffle is slidably connected to the bottom of the constant temperature chamber 232.

[0030] Each ventilation port group 233 has two through holes on its left and right sides, and the lower side of the two through holes is connected to the upper side of the mounting cavity 231.

[0031] As the first embodiment of this utility model, by setting up an incubator 230, the installation cavity 231 at the bottom of the incubator 230 facilitates the quick insertion and removal of the unit box 240. In actual use, when installing or disassembling the unit box 240, the sealing component 234 is activated first, and the baffle is driven by the electric telescopic rod to block the ventilation hole group 233, so as to prevent the constant temperature cavity 232 from being directly connected to the outside and to ensure the cleanliness of the air inside the constant temperature cavity 232.

[0032] Please see Figures 2 to 5 The unit box 240 includes a box body 241, a sealing plate 244, and a handle 245. The box body 241 is provided with a culture chamber 242. A rectangular through groove 243 is formed through the top of the box body 241 near the middle of the culture box 230. The rectangular through groove 243 is connected to the lower end of the ventilation hole group 233. In actual use, the air inside the constant temperature chamber 232 after treatment will communicate with the inside of the culture chamber 242 through the ventilation hole group 233 and the rectangular through groove 243 to achieve the purpose of ventilation during culture.

[0033] A sliding groove is provided on the front side of the upper end of the housing 241, and the width of the sliding groove is greater than the width of the rectangular through groove 243. The rear side of the sliding groove is connected to the rectangular through groove 243. The rear end of the sealing plate 244 is slidably installed on the top of the housing 241 through the sliding groove.

[0034] A sealing ring 246 is provided on the outer wall of the rear end and the outer wall of the front end of the housing 241. The inner wall of the sealing ring 246 is embedded in the inner wall of the housing 241. The outer wall of the sealing ring 246 is slidably connected to the inner wall of the mounting cavity 231. A handle 245 is welded to the middle of the front end of the housing 241. In actual use, the structure and size of the outer wall of the sealing ring 246 match the cross-sectional structure and size of the inner wall of the mounting cavity 231. The sealing ring 246 can prevent external air from entering the rectangular through groove 243 without affecting the normal pushing, pulling and disassembling of the unit box 240.

[0035] As a second embodiment of this utility model, based on the first embodiment described above, in actual use, by setting multiple movable and detachable unit boxes 240 inside the incubator 230, it is possible to avoid other cultures from coming into contact with the outside air when taking them out during unified space culture. When installing or removing the unit box 240, the ventilation hole group 233 needs to be closed first through the sealing member 234. Then, the operator pushes the sealing plate 244 into the slide groove. After the rear side of the sealing plate 244 abuts against the rear end of the slide groove, it will close the rectangular through groove 243. At this point, the inside of the unit box 240 is not directly connected to the outside, and the constant temperature chamber 232 is also sealed. Then, the unit box 240 is pulled by the handle 245. When the unit box 240 is moved to the place where it needs to be opened, the sealing plate 244 is pulled out to open the rectangular through groove 243 for sampling. The entire device has a simple structure and can avoid isolation from the outside air when placing and taking out the culture, and can effectively prevent outside air from entering the culture chamber 242.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
