[0043] Embodiment 2

[0044] Referring to Figures 1 to 11 , this embodiment is based on the previous embodiment.

[0046] It should be noted that the air inlet 22, the air outlet 23 and the plurality of partition plates 21 form an "S" shaped gas channel in the ventilation housing 20.

[0047] According to the above structure, after the heating mechanism 50 heats the gas, the heated gas moves from the air inlet 11 to the inside of the ventilation housing 20 through the air inlet 22, moves upwards along the plurality of partition plates 21 to the air outlet 23, and is discharged through the air outlet 12, in the process, the heated gas warms the culture dish to provide temperature conditions for the bacteria in the culture dish.

[0048] As Figure 7As shown, the inside of the lifting plate 41 is provided with a plurality of first sliding holes 411, and the bottom of the partition plate 21 is fixedly connected with a plurality of first sliding columns 211 which are in sliding fit with the first sliding holes 411 in the vertical direction.

[0049] It should be noted that the lower end of the first screw rod 43 is provided with a first internal hexagonal countersunk hole, so as to facilitate the rotation of the first screw rod 43 by the operator using a tool.

[0050] According to the above structure, when it is necessary to adjust the distance between the lamp tube 42 and the culture dish, the first screw rod 43 is rotated. Since the first screw rod 43 is in threaded connection with the lifting plate 41, the first screw rod 43 drives the lifting plate 41 to move up and down along the bottom of the partition plate 21, and the lifting plate 41 drives the lamp tube 42 to move up and down to adjust the height position of the lamp tube 42, so as to adjust the distance between the lamp tube 42 and the culture dish, and facilitate the adjustment of the illumination intensity received by the culture dish, so as to adjust the illumination condition of the bacteria in the culture dish.

[0051] As shown in Figure 8 and Figure 9 The limiting mechanism 30 comprises a lifting ring 31 which is slidingly installed on the top of the partition plate 21 in the vertical direction. A plurality of limiting clamps 32 are arranged on the lifting ring 31 in the circumferential direction and are slidingly installed on the lifting ring 31 in the radial direction. The top of the lifting ring 31 is slidingly installed with a pressing plate 33 in the vertical direction.

[0052] It should be noted that in the initial state, there is a gap between the lifting ring 31 and the top of the partition plate 21, which is used to warm the bottom of the culture dish when the heated gas passes through the gap.

[0053] According to the above structure, the culture dish containing bacteria is inserted into the lifting ring 31 in the horizontal direction. The limiting clamps 32 clamp the culture dish in the radial direction and limit the culture dish in the horizontal direction. The pressing plate 33 presses the culture dish, so that the pressing plate 33 and the limiting clamps 32 limit the culture dish in the vertical direction, thereby achieving the limiting and fixing of the culture dish.

[0054] As shown in Figure 8 and Figure 9 The inside of the lifting ring 31 is provided with a plurality of second sliding holes 311, and the top of the partition plate 21 is fixedly connected with a plurality of second sliding columns 212 which are in sliding fit with the second sliding holes 311 in the vertical direction. The top of the partition plate 21 is rotatably connected with a second screw rod 34 which is in threaded connection with the lifting ring 31.

[0055] It should be noted that the upper end of the second screw rod 34 is provided with a second internal hexagonal countersunk hole, so as to facilitate the rotation of the second screw rod 34 by the operator using a tool.

[0056] According to the above structure, when it is necessary to adjust the distance between the bottom of the culture dish and the partition plate 21, the second screw rod 34 is rotated, and since the second screw rod 34 is in threaded connection with the lifting ring 31, the second screw rod 34 drives the lifting ring 31 to move up and down along the top of the partition plate 21, and the lifting ring 31 drives the limiting clip 32 to move up and down to adjust the height position of the culture dish, so as to adjust the distance between the bottom of the culture dish and the top of the partition plate 21, so that the heated gas can pass through the gap between the bottom of the culture dish and the partition plate 21, so as to facilitate the heating of the bottom of the culture dish, reduce the situation that the bottom of the culture dish is difficult to heat in the traditional way that multiple culture dishes are stacked together, and facilitate the adjustment of the temperature condition of the bacteria in the culture dish.

[0057] As shown in Figure 9 , the lifting ring 31 is provided with a sliding groove 312 on the side close to the limiting clip 32 in the radial direction, the limiting clip 32 is in sliding fit with the sliding groove 312, and a plurality of first springs 35 are connected between the limiting clip 32 and the sliding groove 312. The top of the limiting clip 32 is rotationally connected with a roller 321.

[0058] According to the above structure, after the culture dish is placed in the limiting mechanism 30, the bottom of the culture dish is in contact with the limiting clip 32, so that the limiting clip 32 supports the bottom of the culture dish upward, and the first spring 35 pushes the limiting clip 32 to move inward along the lifting ring 31 under the elastic action, so that the limiting clip 32 drives the roller 321 to be close to the outer wall of the culture dish, so that the plurality of limiting clips 32 limit the culture dish, and the limiting clip 32 is matched with the sliding groove 312, so that the process of the limiting clip 32 sliding in the radial direction of the lifting ring 31 is more stable.

[0059] As shown in Figure 9 , the top of the lifting ring 31 is fixedly connected with a stand column 313, the pressing plate 33 is in sliding fit with the stand column 313 in the vertical direction, and a plurality of second springs 36 are connected between the top of the pressing plate 33 and the stand column 313.

[0060] According to the above structure, after the culture dish is placed in the limiting mechanism 30, the second spring 36 pushes the pressing plate 33 to move downward under the elastic action, so that the pressing plate 33 and the limiting clip 32 limit the culture dish in the vertical direction, so as to facilitate the fixation of the culture dish, and the pressing plate 33 is matched with the stand column 313, so that the process of the pressing plate 33 sliding along the lifting ring 31 is more stable.

[0061] As shown in Figure 9 , the end of the pressing plate 33 away from the lifting ring 31 is rotationally connected with a plurality of rollers 331, and the outer side of the roller 331 extends to the lower side of the pressing plate 33.

[0062] According to the above structure, in the process of inserting the culture dish into the limiting mechanism 30, the top of the culture dish is in contact with the outer side of the roller 331, so that the relative rolling between the roller 331 and the top of the culture dish is facilitated, and when the culture dish moves relative to the pressing plate 33 during the process of inserting the culture dish into the limiting mechanism 30, the interference friction between the pressing plate 33 and the top of the culture dish is reduced.

[0063] As shown in Figure 2 and Figure 11 The first filter plate 54 is fixedly connected to the connecting shell 51.

[0064] According to the above structure, when the fan 52 inhales the gas outside the device, the first filter plate 54 prevents dust and other impurities in the external gas from entering the internal part of the device, reducing the pollution of the culture dish and the bacteria in the culture dish caused by the dust and other impurities entering the ventilation shell 20.

[0065] As shown in Figure 2 and Figure 3 The second filter plate 13 is fixedly connected to the outer wall of the box body 10.

[0066] According to the above structure, the second filter plate 13 prevents dust and other impurities outside the device from entering the internal part of the ventilation shell 20 through the air outlet 12, reducing the pollution of the culture dish and the bacteria in the culture dish caused by the dust and other impurities in the ventilation shell 20.

[0067] The working principle of the present application is that the limiting mechanism 30 limits and fixes the culture dish inserted into the limiting mechanism 30, adjusts the distance between the lamp tube 42 and the culture dish, adjusts the number of opened lamp tubes 42, adjusts the light intensity received by the bacteria in the culture dish, and opens the lamp tubes 42 of different diameters to adapt to culture dishes of different diameters, so as to individually adjust the light conditions of the culture dishes in the device, improve the applicability and convenience of bacterial culture, and the plurality of ventilation shells 20 separate the culture dishes, so that the heating mechanism 50 works on the culture dish in the corresponding ventilation shell 20, thereby adjusting the temperature conditions of the bacteria in different culture dishes and improving the convenience of bacterial culture.

[0068] The above is only the preferred embodiment of the present application, and it should be noted that for ordinary skilled persons in the art, without departing from the principle of the present application, some improvements and refinements can be made, which should also be considered as the protection scope of the present application.
