Description

Technical Field

[0001] This utility model relates to the field of bacterial culture technology, and in particular to a bacterial constant temperature incubator. Background Technology

[0002] Microbial culture systems are indispensable tools in modern bioscience and technology. They provide a stable temperature environment and are specifically designed and manufactured to ensure the optimal growth and reproduction of microbial strains. They have wide applications in medical research, industrial fermentation, bioengineering, food safety testing, and environmental microbiology.

[0003] When using a constant temperature incubation device to cultivate microorganisms, the temperature is increased by a heating plate installed on one side of the device. When the heating plate is powered on and starts heating, the temperature on one side of the device is higher than that on the other side, resulting in uneven heat distribution inside the device. This reduces the detection accuracy of the temperature sensor and consequently reduces the effect of constant temperature regulation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as uneven heat distribution inside the device, which reduces the detection accuracy of the temperature sensor, by proposing a constant temperature incubator for bacterial strains.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a constant temperature incubator for microbial cultures, including an open box with an air inlet and an air outlet on one side. A sealing mechanism for sealing the air inlet and outlet is connected to the open box. A heating plate is connected inside the open box, and a sealing cover is also connected inside the open box. The heating plate is located inside the sealing cover. Several conduits are evenly spaced along the length of the sealing cover, and one end of each conduit is connected to the same U-shaped tube. Several first through holes are evenly spaced along the length of the inner wall of the U-shaped tube. A limiting mechanism is connected to the bottom of the open box, and an incubation chamber is located above the limiting mechanism. A temperature sensor is connected to the inner wall of the incubation chamber.

[0007] Preferably, the sealing mechanism includes a fixed plate, which is fixedly connected to the open box. An electric telescopic rod is fixedly connected to the lower surface of the fixed plate, and a sealing plate is fixedly connected to the telescopic end of the electric telescopic rod. The sealing plate is in contact with the air inlet and air outlet.

[0008] Preferably, a sealing gasket is fixedly connected to the sealing plate, and the sealing gasket is in contact with the open box.

[0009] Preferably, the limiting mechanism includes a support plate, which is fixedly connected to the bottom of the open box. A plurality of support columns are fixedly connected to the upper end of the support plate, and the same limiting frame is fixedly connected to the upper end of each support column. The limiting frame is connected to the incubator.

[0010] Preferably, the support plate has a plurality of second through holes at equal intervals along its length.

[0011] Preferably, a number of lighting lamps are connected at equal intervals along the length of the upper interior of the open box.

[0012] The beneficial effects of the constant temperature culture device for bacterial strains proposed in this utility model are as follows:

[0013] After the heating plate is activated, the gas inside the sealed cover is heated. The heated gas is then introduced into the U-shaped tube through a conduit. The hot gas inside the conduit is released from different first through holes, which facilitates the rapid dispersion of the hot gas into the open box, reduces the temperature difference between different areas inside the open box, and improves the accuracy of temperature measurement by the temperature sensor.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1: Refer to Figure 1-3 A constant temperature incubator for microbial strains includes an open box 1, a rotating door 2 rotatably connected to the open opening of the open box 1, an air inlet 3 and an air outlet 4 on one side of the open box 1, a sealing mechanism 5 for sealing the air inlet 3 and the air outlet 4 connected to the open box 1, a heating plate 6 connected inside the open box 1, a sealing cover 7 connected inside the open box 1, the heating plate 6 located inside the sealing cover 7, a plurality of conduits 8 connected at equal intervals along the length direction on the sealing cover 7, one end of each conduit 8 connected to the same U-shaped tube 9, a plurality of first through holes 10 at equal intervals along the length direction on the inner wall of the U-shaped tube 9, a limiting mechanism 11 connected to the bottom of the interior of the open box 1, an incubator 12 provided at the upper end of the limiting mechanism 11, a temperature sensor 13 connected to the inner wall of the incubator 12, and a plurality of light lamps 14 connected at equal intervals along the length direction on the upper interior of the open box 1.

[0021] Work process:

[0022] When in use, push the rotating door 2 to open the open box 1, put the inoculum into the incubator 12, and then push the rotating door 2 to seal the open box 1. The sealing mechanism 5 seals the air inlet 3 and the air outlet 4. The temperature sensor 13 detects the temperature inside the incubator 12.

[0023] When the temperature inside the incubator 12 is low, the controller controls the heating plate 6 to be powered on and started. After the heating plate 6 is started, it heats the gas inside the sealed cover 7. The heated gas is introduced into the U-shaped tube 9 through the conduit 8. The hot gas in the conduit 8 is released from different first through holes 10, which facilitates the rapid dispersion of hot gas into the open box 1, reduces the temperature difference between different areas inside the open box 1, and improves the accuracy of temperature measurement by the temperature sensor 13. After the temperature sensor 13 detects that the temperature has reached the set value, the controller controls the heating plate 6 to be turned off.

[0024] When the temperature inside the incubator 12 is high, the controller controls the sealing mechanism 5 to move and separate from the air inlet 3 and air outlet 4. External gas enters the open box 1 through the air inlet 3, and the gas inside the open box 1 is released from the air outlet 4, reducing the temperature inside the open box 1. After the temperature inside the open box 1 drops to the set value, the sealing mechanism 5 seals the air inlet 3 and air outlet 4 to ensure that the inside of the open box 1 is in a constant temperature state.

[0025] Example 2: In Example 1, when releasing hot gas from the open box 1, it was impossible to control the opening and closing of the air inlet 3 and the air outlet 4 in a timely manner, referring to... Figure 3In another preferred embodiment of this utility model, the difference from embodiment 1 is that the sealing mechanism 5 includes a fixed plate 51, which is fixedly connected to the open box 1. An electric telescopic rod 52 is fixedly connected to the lower surface of the fixed plate 51. A sealing plate 53 is fixedly connected to the telescopic end of the electric telescopic rod 52. The sealing plate 53 is in contact with the air inlet 3 and the air outlet 4. A sealing gasket 54 is fixedly connected to the sealing plate 53 and is in contact with the open box 1. Initially, the sealing plate 53 seals the air inlet 3 and the air outlet 4 through the sealing gasket 54. When cooling down, the electric telescopic rod 52 is started and drives the sealing plate 53 to move downward by a set distance. The sealing plate 53 drives the sealing gasket 54 to move, so that the sealing gasket 54 is misaligned with the air inlet 3 and the air outlet 4. When sealing, the electric telescopic rod 52 drives the sealing plate 53 to move upward by a set distance to reset, sealing the air inlet 3 and the air outlet 4. The opening and closing of the air inlet 3 and the air outlet 4 can be controlled in a timely manner.

[0026] Example 3: In Example 1, when supporting the incubator 12, it was inconvenient to remove the incubator 12. (Refer to...) Figure 4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the limiting mechanism 11 includes a support plate 111, the support plate 111 is fixedly connected to the bottom of the open box 1, and a plurality of support columns 113 are fixedly connected to the upper end of the support plate 111. The upper end of each support column 113 is fixedly connected to the same limiting frame 114, the limiting frame 114 is connected to the incubator 12, and a plurality of second through holes 112 are equally spaced along the length direction on the support plate 111. The support plate 111 fixes the support columns 113, the support columns 113 support the limiting frame 114, and the limiting frame 114 limits and fixes the incubator 12. It is not necessary to fix the incubator 12, so it is convenient to take out the incubator 12. At the same time, a plurality of second through holes 112 are opened on the support plate 111 to facilitate the flow of hot gas through the support plate 111.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
