Description

Technical Field

[0001] This utility model relates to the field of microbial culture technology, and in particular to a microbial culture device for teaching bioengineering. Background Technology

[0002] Microbial culture devices for bioengineering teaching are equipment used to cultivate microorganisms. They can provide suitable environmental conditions such as temperature, humidity, and gas composition for microbial growth to promote their growth and reproduction. Microbial culture devices can be divided into various types, including ordinary incubators, carbon dioxide incubators, anaerobic incubators, and constant temperature and humidity incubators. Microbial culture devices for bioengineering teaching are widely used in teaching and research.

[0003] Existing microbial culture devices for bioengineering teaching generate water vapor during use. When the water vapor comes into contact with the culture dish, it forms water droplets. When the culture dish is removed from the biocabinet, the water droplets spill all over the floor, making the teaching area slippery and inconvenient for teachers and students to move around. In order to solve this technical problem, this utility model proposes a microbial culture device for bioengineering teaching. Utility Model Content

[0004] The main objective of this invention is to provide a microbial culture device for teaching bioengineering, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A microbial culture device for teaching bioengineering includes a biological cabinet and a culture dish. The culture dish is placed inside the biological cabinet, and a flow guide is provided above the culture dish. The flow guide is shaped like a V-shape, with the middle higher and the ends lower, and has an inclined angle. The inner wall of the biological cabinet is connected to two water tanks, which are symmetrical and located below the flow guide. The inner side of each water tank is connected to a drain pipe. The water tank has an inclined angle, with the end of the water tank lower than the end of the drain pipe. One end of the drain pipe is connected to a water storage tank, and the drain pipe communicates with the interior of the water storage tank. The water storage tank is connected to the inner bottom wall of the biological cabinet.

[0007] Preferably, an output pipe is connected to one side of the water storage tank, and the output pipe is connected to the inside of the water storage tank. A valve is connected to the end of the output pipe located outside the biological cabinet.

[0008] Preferably, the inner wall of the biological cabinet is connected to a support frame, the lower surface of the support frame is connected to a slide rail, and the outer surface of the slide rail is slidably connected to the inner wall of the flow guide shroud.

[0009] Preferably, the inner wall of the biological cabinet is connected to a slide rail, and the inner wall of the slide rail is rotatably connected to multiple rollers, which are arranged in an equidistant array, with the outer surface of the rollers in contact with the lower surface of the culture dish.

[0010] Preferably, the outer surface of the biological cabinet is hinged with a cabinet door, and a sealing gasket is connected to one side of the biological cabinet, and the sealing gasket is made of rubber.

[0011] Preferably, the lower surface of the biological cabinet is equipped with four casters, which are located at the four corners of the biological cabinet.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the combination of a flow guide, a water tank, and a drain pipe creates a barrier against water vapor, causing it to condense into water droplets. These droplets are then guided by the angled flow guide to the water tank, where they are collected and prevented from flowing outwards. Inside the water tank, the droplets flow through the drain pipe into a water storage tank, where they are concentrated. This reduces the contact between water vapor and the petri dish, minimizing the amount of water droplets carried when the petri dish is removed and improving the dryness of the teaching area.

[0014] In this invention, the cooperation between the support frame and the slide rail allows the support frame to maintain the stability of the slide rail, enabling the slide rail to provide support for the fairing and maintain its stability. At the same time, the slide rail can guide the movement direction of the fairing, making the installation of the slide rail convenient. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1-6 As shown, a microbial culture device for teaching bioengineering includes a biological cabinet 1 and a petri dish 2. The petri dish 2 is placed inside the biological cabinet 1 to contain the microbial sample to be cultured. The biological cabinet 1 creates an independent space for the sample and provides an appropriate environmental temperature.

[0024] A flow guide hood 3 is installed above the petri dish 2. The flow guide hood 3 is shaped like a herringbone, with a higher middle and lower ends. The flow guide hood 3 has an inclined angle. After the sample emits water vapor, the water vapor rises and condenses into water droplets upon contact with the flow guide hood 3. The water droplets flow downwards under the guidance of the flow guide hood 3. The inner wall of the biocabinet 1 is connected to two water tanks 4. The two water tanks 4 are symmetrical and located below the flow guide hood 3. The water droplets flowing downwards along the flow guide hood 3 fall into the water tank 4. The inner side of the water tank 4 is connected to a drain pipe 5. The water tank 4 has an inclined angle, with the end of the water tank 4 lower than the end of the drain pipe 5. The water droplets are collected uniformly by the water tank 4 and flow from high to low under the influence of the inclined angle of the water tank 4.

[0025] One end of the drain pipe 5 is connected to the water storage tank 6. The drain pipe 5 guides the flow of water, and the water storage tank 6 collects the water. The drain pipe 5 is connected to the inside of the water storage tank 6, and the water storage tank 6 is connected to the inner bottom wall of the biological cabinet 1. Water droplets flow from inside the water tank 4 to the drain pipe 5, and are guided into the water storage tank 6 for unified collection.

[0026] A water storage tank 6 is connected to an output pipe 7 on one side, and the output pipe 7 is connected to the inside of the water storage tank 6. A valve 8 is connected to the end of the output pipe 7 located outside the biological cabinet 1. Water inside the water storage tank 6 is discharged to the outside through the output pipe 7, and the valve 8 controls the opening and closing of the output pipe 7.

[0027] The inner wall of the biological cabinet 1 is connected to a support frame 9, and the lower surface of the support frame 9 is connected to a slide rail 10. The outer surface of the slide rail 10 is slidably connected to the inner wall of the flow guide 3. The support frame 9 maintains the stability of the slide rail 10, so that the slide rail 10 has a supporting force to provide support for the flow guide 3.

[0028] The inner wall of the biocabinet 1 is connected to a slide rail 11, and multiple rollers 12 are rotatably connected to the inner wall of the slide rail 11. The multiple rollers 12 are arranged in an equidistant array. The outer surface of the rollers 12 is in contact with the lower surface of the culture dish 2. The rollers 12 are supported by the guide rail to make the rollers 12 stable. When the culture dish 2 slides into or out of the biocabinet 1, the rolling of the rollers 12 reduces the friction between the culture dish 2 and the culture dish 2, making it easier for the culture dish 2 to move.

[0029] The outer surface of the biological cabinet 1 is hinged with a cabinet door 13. A sealing gasket 14 is connected to one side of the biological cabinet 1. The sealing gasket 14 is made of rubber. Rubber has good extensibility. When the cabinet door 13 is closed, it compresses the sealing gasket 14, causing the sealing gasket 14 to fill the gap between the biological cabinet 1 and the cabinet door 13, thereby increasing the airtightness of the biological cabinet 1 and making the interior of the biological cabinet 1 an independent space.

[0030] The lower surface of the biological cabinet 1 is equipped with four casters 15, which are located at the four corners of the biological cabinet 1. When the biological cabinet 1 is no longer needed in the teaching area, it needs to be moved to the placement area. The rolling function of the casters 15 makes it easy to move the biological cabinet 1, reducing physical exertion.

[0031] It should be noted that in actual use, the petri dish 2 is first placed inside the biological cabinet 1. After the petri dish 2 comes into contact with the roller 12, it is pushed to move into the biological cabinet 1. At the same time, the petri dish 2 drives the roller 12 to rotate. After rising inside the biological cabinet 1, the sample inside the petri dish 2 emits water vapor. After the water vapor rises, it comes into contact with the guide hood 3. Then the water vapor condenses into water droplets on the outside of the guide hood 3. The water droplets flow downwards along the tilt angle of the guide hood 3 and finally fall into the water tank 4. The water droplets flow along the water tank 4 to the drain pipe 5. The water droplets are guided by the drain pipe 5 to the water storage tank 6 for unified storage.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
