[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0030] Please see Figures 1-7 The present invention provides the following technical solution:

[0031] Example 1: The anti-contamination effect of existing bacterial culture instruments used in laboratory medicines needs to be improved. To solve this technical problem, this example discloses the following technical content:

[0032] A contamination-resistant bacterial culture instrument for laboratory use includes an incubator 1, a sterilization mechanism 2, and an adjustment mechanism 7. The incubator 1 is rotatably connected to a door 3. A viewing glass 4 is fixedly installed on the top wall of the incubator 1 and inside the door 3. The sterilization mechanism 2 and a culture table 5 are installed inside the incubator 1. The sterilization mechanism 2 is located at the rear end of the culture table 5. An electric heating wire 6 is fixedly installed inside the wall of the culture table 5. An adjustment mechanism 7 is installed at the bottom outside the incubator 1. A stabilizing component 8 is installed behind the adjustment mechanism 7. A placement groove is opened inside the top wall of the culture table 5, and a culture dish is placed in the placement groove of the culture table 5.

[0033] like Figure 2-5 and Figure 7As shown, the incubator 1 is equipped with a sterilization mechanism 2 and a culture platform 5. The sterilization mechanism 2 is located at the rear end of the culture platform 5. The sterilization mechanism 2 includes an exhaust fan 201, a filter screen 202, a partition 203, a first connecting plate 204, a second connecting plate 205, a lid 206, and a sealing ring 207. When the exhaust fan 201 is turned on, the filter screen 202 is located on the left side of the exhaust end of the exhaust fan 201. A hole is opened in the left side wall of the partition 203. The exhaust fan 201 draws air from the air in the incubator 1 located near the negative end of the culture platform 5 through the hole. The air is drawn in by the exhaust fan 201 and first passes through the filter screen 202 to purify the air. The exhaust end of the exhaust fan 201 is fixedly installed inside the right side of the partition 203. The purified air is then introduced into the vicinity of the culture platform 5 to sterilize the incubator 1. An electric heating wire 6 is fixedly installed inside the wall of the culture platform 5. A placement slot is opened inside the top wall of the culture platform 5, in which a culture dish is placed. The electric heating wire 6 is turned on to heat the culture platform 5, thereby heating the culture dish and thus subjecting the bacteria inside to high-temperature treatment.

[0034] A cover 206 is provided at the top of the filter screen 202. The cover 206 covers the opening at the rear top of the incubator 1. Sealing rings 207 are fixedly installed on the four sides of the bottom of the cover 206. The sealing rings 207 are located in the opening at the rear top of the incubator 1, thereby improving the sealing performance inside the incubator 1 and thus improving the efficiency of the sterilization mechanism 2. The cover 206 is fixedly installed at the top of the second connecting plate 205. A first connecting plate 204 is fixedly connected to the top outer side of the filter screen 202. The first connecting plate 204 is located between the two second connecting plates 205. Plate 204 is fixedly connected to the two second connecting plates 205 by bolts. When the filter screen 202 needs to be replaced, hold the handle at the top of the box cover 206 and lift it upwards so that the filter screen 202 leaves the incubator 1. Remove the bolts to remove the filter screen 202. Align the holes in the first connecting plate 204 of the new filter screen 202 with the holes in the second connecting plate 205, fix it with bolts, and place the filter screen 202 in the incubator 1. The material used for the filter screen 202 is selected according to the needs of the bacteria cultured in the incubator 1.

[0035] Example 2: Existing laboratory bacterial culture instruments are not convenient for observing bacteria in the culture dishes. To solve this technical problem, this example discloses the following technical content:

[0036] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, a viewing glass 4 is fixedly installed on the top wall and the inner wall of the door 3 of the incubator 1, allowing bacteria to be observed inside the incubator 1. An adjustment mechanism 7 is installed on the bottom of the outer side of the incubator 1. The adjustment mechanism 7 includes a base 701, a lead screw 702, a "┓"-shaped plate 703, a lifting platform 704, a diagonal rod 705, a large transmission wheel 706, a small transmission wheel 707, a transmission belt 708, and a motor 709. When the motor 709 is started, the output end of the motor 709 is fixedly connected to the small transmission wheel 707, and the motor 709 drives the small transmission wheel 707 to rotate. A transmission belt 708 is provided on the outer side of the large transmission wheel 706 and the small transmission wheel 707, and the large transmission wheel 706 is rotated through the transmission belt 708. The large transmission wheel 706 is fixedly installed on the top of the lead screw 702. A lead screw 702 is rotatably connected to the top of the base 701. A large transmission wheel 706 drives the lead screw 702 to rotate. A "┓" shaped plate 703 is threadedly connected to the outside of the lead screw 702. The lead screw 702 drives the "┓" shaped plate 703 to rise and fall. A lifting platform 704 is installed at the front height of the "┓" shaped plate 703. The "┓" shaped plate 703 drives the lifting platform 704 to rise and fall. An incubator 1 is fixedly installed at the top of the lifting platform 704. The lifting platform 704 drives the incubator 1 to rise and fall, adjusting it to a height convenient for the observer to observe. A diagonal rod 705 is fixedly installed at the bottom of the "┓" shaped plate 703. The two ends of the diagonal rod 705 are fixedly connected to the front end and rear end of the "┓" shaped plate 703, respectively, thereby improving the stability of the lifting platform 704 and the firmness of its connection with the "┓" shaped plate 703.

[0037] Example 3: The technical content disclosed in this example is a further improvement based on Example 2 above. The adjustment mechanism of the existing bacterial culture instrument for laboratory use is relatively unstable. To solve this technical problem, this example discloses the following technical content:

[0038] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a stabilizing component 8 is installed on the rear side of the adjusting mechanism 7. The stabilizing component 8 includes a fixed column 801, a sliding groove 802, a connecting rod 803, and a roller 804. Sliding grooves 802 are provided in both the left and right walls of the fixed column 801. The roller 804 is rotatably connected to the outside of the connecting rod 803. The end of the connecting rod 803 away from the roller 804 is fixedly connected to the rear end of the outer side of the "┓" shaped plate 703. The roller 804 is provided in the sliding groove 802. When the "┓" shaped plate 703 is raised or lowered, the roller 804 rotates and moves in the sliding groove 802, thereby reducing the influence of the gravity of the incubator 1 on the "┓" shaped plate 703, making the movement of the "┓" shaped plate 703 more stable and smooth.

[0039] The incubator 1 has a door 3 that is rotatably connected to the front. Opening the door 3 allows you to take out the culture dish inside.

[0040] The above completes the series of operations for this contamination-proof laboratory bacterial culture instrument. Any content not described in detail in this instruction belongs to the prior art known to those skilled in the art.
