[0024] See also Figure 1 , Figure 2 as well as Figure 3 The utility model discloses a selective separation and culture kit for Escherichia coli, comprising a box body 10, a test tube rack 20 and a stirring rack 30. A cavity 11 is provided inside the box body 10, and an opening is provided at the top of the cavity 11. The top opening of the cavity 11 can be used for a reagent tube 50 to be placed in or taken out.
[0025] The test tube rack 20 is installed in the cavity 11, and a plurality of jacks are provided on the test tube rack 20, and the jacks can be used for inserting the reagent tubes 50, that is, when the reagent tubes 50 are placed, the reagent tubes 50 can be inserted into the jacks of the test tube rack 20 through the top opening of the cavity 11. In addition, the stirring rack 30 is installed at the top of the box body 10 and is located above the test tube rack 20, and the stirring rack 30 can move along the width direction and the height direction of the box body 10. A plurality of stirring rods 40 are provided on the stirring rack 30, and the plurality of stirring rods 40 are installed at the bottom end of the stirring rack 30. Specifically, after the stirring rack 30 moves along the width direction of the box body 10, the plurality of stirring rods 40 can be made to correspond one-to-one with the plurality of jacks or staggered; the plurality of stirring rods 40 are used to extend into the reagent tubes 50 after corresponding one-to-one with the plurality of jacks.
[0026] On the basis of the above structure, when using the selective separation and culture kit for Escherichia coli of the utility model, the reagent for culturing bacteria can be placed in the reagent tube 50, and then the reagent tubes 50 of different samples are inserted into the multiple jacks of the test tube rack 20. Thereafter, the stirring rack 30 is moved so that the multiple stirring rods 40 on the stirring rack 30 can move along the width direction of the box body 10 to correspond to the multiple reagent tubes 50, and then the stirring rack 30 is moved downward along the height direction of the box body 10 until the stirring rod 40 extends into the reagent tube 50. In this way, the reagent in the reagent tube 50 can be stirred by the stirring rod 40 on the stirring rack 30, and the operation can be performed after adding the sample during the culture process.
[0027] After the stirring action is completed, the stirring frame 30 can be directly moved upward along the height direction of the box body 10, and the stirring rod 40 can be withdrawn from the reagent tube 50, and the reagent tube 50 can be cultured statically. That is, the culture process is carried out by moving the stirring rod 40 on the stirring frame 30, and there is no need to move the test tube rack 20, which reduces the shaking of the reagent tube 50 and stabilizes the culture process.
[0028] Further, guide grooves can also be provided on both sides of the opening, and the guide grooves are provided on the side walls of the cavity 11. Specifically, the guide grooves include a horizontal groove section 131 and a vertical groove section 132, and the horizontal groove section 131 extends along the width direction of the box body 10. In addition, the vertical groove section 132 extends along the height direction of the box body 10, and the top of the vertical groove section 132 is connected with the end of the horizontal groove section 131. Correspondingly, a guide is provided on the side of the stirring rack 30, and the guide is slidably matched with the guide groove. In this way, the sliding guidance of the stirring rack 30 can be achieved by sliding the guide in the guide groove. Specifically, when the stirring rod 40 on the stirring rack 30 needs to perform a stirring action, the guide of the stirring rack 30 can be along the horizontal groove section 131 to the top position of the vertical groove section 132. At this time, the stirring rod 40 on the stirring rack 30 can correspond to the reagent tube 50, and then the guide slides relatively along the vertical groove section 132.
[0029] It should be noted that the guide member can be a guide wheel 31, which can be slidably connected to the guide groove for rolling guidance. The guide wheel 31 can be a rubber wheel, and the wheel surface of the rubber wheel can be frictionally matched with the side wall of the guide groove, that is, the rubber wheel needs to be manually slid to make it slide in the guide groove without rolling. The bottom end of the vertical groove section 132 can limit the movement position of the stirring frame 30, so that the stirring rod 40 can just extend into the reagent tube 50.
[0030] Of course, the stirring frame 30 is provided with a through hole, and the stirring rod 40 can be rotatably inserted into the through hole of the stirring frame 30, and a rubber ring or a silicone ring can be provided between the stirring rod 40 and the through hole, so as to increase the friction between the two and prevent the stirring rod 40 from sliding down.
[0031] Furthermore, the horizontal slot section 131 and the vertical slot section 132 are connected by an arc surface, so that an arc transition is adopted at the connection position of the horizontal slot section 131 and the vertical slot section 132, and the guide wheel 31 can smoothly transition when sliding.
[0032] Furthermore, guide plates 32 are provided on both sides of the stirring frame 30 , and the guide wheel 31 is rotatably mounted on the guide plate 32 , so that the guide wheel 31 can be assembled through the guide plate 32 , and the installation structure of the guide wheel 31 is stable.
[0033] Furthermore, both side walls of the cavity 11 are provided with insertion grooves 111, and both sides of the test tube rack 20 are inserted into the insertion grooves 111, so that both sides of the test tube rack 20 can be connected to the cavity 11 in an insertion manner, which is convenient for disassembly and assembly and subsequent maintenance.
[0034] Furthermore, a support plate 14 is provided at the bottom end of the test tube rack 20, and the support plate 14 is spaced apart from the bottom end of the test tube rack 20. The support plate 14 can be used to support the bottom end of the reagent tube 50 of the test tube rack 20. After the reagent tube 50 is inserted, it is supported by the support plate 14, and is more stable after assembly.

Specifically, a covering end plate 12 can be provided at the front end of the box body 10, and the covering end plate 12 can be spaced from the front end of the test tube rack 20 to form an air inlet. In this way, when the fan 60 is started, external air can be brought in through the air inlet, and the air is dissipated through the heat sink, and then the air flow is guided to the air outlet by the fan 60, so that the inside of the box body 10 can be cooled, so that the inside of the box body 10 can be ventilated and cooled, and the culture environment temperature of the reagent tube 50 is stable.
[0036] Furthermore, the heat sink includes a plurality of heat sinks 70 arranged at intervals, so that heat can be dissipated by the plurality of heat sinks 70 . The plurality of heat sinks 70 can be made of aluminum sheets and fixedly connected in an integrally formed manner.
