Description

Technical Field

[0001] This utility model relates to the field of biological culture technology, and in particular to a multifunctional liquid supply device for biological culture. Background Technology

[0002] Biological culture refers to the artificial creation of culture conditions, such as culture temperature, to enable certain organisms to grow and reproduce rapidly. Biological culture can be divided into pure culture and mixed culture. The former refers to the cultivation and utilization of a purified single strain, while the latter refers to the cultivation of mixed strains or natural samples. During the cultivation process, the organisms need to be supplied with liquid.

[0003] Currently, the culture medium is generally supplied manually using a syringe. This manual method is inefficient, prone to bacterial growth, and reduces the survival rate of the cultured organisms. Furthermore, during manual injection, the culture medium often accumulates in one spot within the culture dish, requiring time to spread throughout the dish. Additionally, there are instances where the corners and edges are not supplied with the medium, resulting in uneven growth of microorganisms within the dish, which is detrimental to their development. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a multifunctional liquid supply device for biological culture, which solves the technical problems of low efficiency and easy bacterial growth in manual liquid supply, as well as uneven liquid supply in existing technologies, and achieves the purpose of automatic and uniform liquid supply.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a multifunctional liquid supply device for biological culture, comprising a culture tray installed in an incubator, wherein the culture tray is provided with a uniform liquid supply mechanism for uniformly supplying liquid to the culture tray.

[0006] The uniform liquid supply mechanism includes a liquid supply tank installed on the top of the incubator.

The bottom of the liquid supply pipe extends into the interior of the incubator and is located above the culture tray. A vibration motor is installed at the center of the bottom of the culture tray, and vibration springs are installed at the four corners of the bottom. A limiting sleeve is installed inside the vibration spring, and a guide rod slides up and down inside the limiting sleeve. The top of the guide rod is connected to the bottom of the culture tray. A rotating component that drives the culture tray to rotate is installed below the culture tray. A mixing component that stirs the culture medium and prevents sedimentation is provided inside the liquid supply tank.

[0007] Preferably, an electric heating plate for maintaining a constant temperature of the culture medium is installed in the mounting groove inside the liquid supply tank, and an electric heating wire is installed in the culture tray.

[0008] Preferably, the rotating assembly includes a chassis on which a vibration motor and a vibration spring are mounted, a rotating shaft is mounted on the bottom of the chassis, and a rotating motor for driving the rotating shaft is installed in a power slot opened inside the incubator.

[0009] Preferably, the mixing assembly includes a rotating shaft rotatably connected to the liquid supply tank, U-shaped mixing rods are vertically and equidistantly mounted on the rotating shaft, a rotating cylinder is rotatably connected to the U-shaped mixing rods, a stirring plate is circumferentially and equidistantly mounted on the rotating cylinder, and cutting holes are uniformly opened through the stirring plate, and a drive motor for driving the rotating shaft to rotate is installed on the liquid supply tank.

[0010] Preferably, the incubator has symmetrical through-holes on both the left and right sides, and dust filters are installed inside the air vents.

[0011] Preferably, the incubator is equipped with a controller, and the uniform liquid supply mechanism is electrically connected to the controller.

Detailed Implementation

[0024] 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.

[0025] Example 1

[0026] Addressing the issues of low efficiency, easy bacterial growth, and uneven culture medium distribution in existing manual culture media, this embodiment provides a multifunctional vessel-based culture medium supply device. Please refer to... Figures 1-5 This embodiment provides a multifunctional liquid supply device for biological culture, capable of automatically and uniformly supplying liquid. The device includes a culture tray 2 installed inside an incubator 1, and a uniform liquid supply mechanism 3 on the culture tray 2 for uniformly supplying liquid to the culture dishes. The uniform liquid supply mechanism 3 supplies liquid to the culture dishes on the culture tray 2 without manual operation, resulting in higher efficiency, preventing bacterial death of microorganisms, and ensuring uniform distribution of the culture medium within the dishes, which is more conducive to microbial growth.

[0027] Because existing artificial culture medium supply technology is inefficient and prone to bacterial growth, and also suffers from uneven culture medium supply, this device is equipped with a uniform culture medium supply mechanism 3. The uniform culture medium supply mechanism 3 includes a supply tank 301 mounted on the top of the incubator 1. A suction pump 302 is mounted on the supply tank 301, and a supply pipe 303 is installed at the outlet of the suction pump 302. The bottom of the supply pipe 303 extends into the interior of the incubator 1 and is located above the culture tray 2. A vibration motor 304 is mounted at the center of the bottom of the culture tray 2, and vibration springs 305 are installed at each of its four corners. A limiting sleeve 306 is installed inside the vibration spring 305, and a guide rod 307 slides up and down within the limiting sleeve 306. The top of the slide bar 307 is connected to the bottom of the culture tray 2. A rotating component 308 is installed below the culture tray 2 to drive its rotation. A mixing component 309 is installed in the supply tank 301 to stir the culture medium and prevent sedimentation. When it is necessary to supply the culture dish on the culture tray 2, the suction pump 302 is started to pump the culture medium in the supply tank 301 into the supply pipe 303 and drip it into the culture dish on the culture tray 2. At this time, the culture medium accumulates in one place. Then, the vibration motor 304 is started to drive the culture tray 2 to vibrate up and down under the elastic pull of the vibration spring 305, so as to quickly and evenly distribute the culture medium in the culture dish, which is more conducive to the growth of microorganisms.

[0028] When culturing microorganisms, it is necessary to control the growth temperature of the microorganisms and set the growth rate of microorganisms at different temperatures as a control group. The temperature of the culture medium also needs to be kept constant to avoid microbial death caused by temperature changes. Therefore, the device has an electric heating plate 310 installed in the installation groove inside the supply tank 301 to maintain the constant temperature of the culture medium, and an electric heating wire 311 installed in the culture tray 2. The electric heating plate 310 maintains the constant temperature of the culture medium in the supply tank 301 to avoid microbial death caused by the culture medium temperature being too low during supply. Maintaining a constant temperature is also beneficial to maintaining the nutrients in the culture medium. The electric heating wire 311 controls the growth temperature of microorganisms in different culture dishes on the culture tray 2 to compare and summarize the most suitable temperature.

[0029] To better observe the growth of microorganisms in different culture dishes on the culture tray 2 and to supply liquid, the device is also equipped with a rotating component 308. The rotating component 308 includes a base plate 3081 with a vibration motor 304 and a vibration spring 305 installed at the bottom. A rotating shaft 3082 is installed at the bottom of the base plate 3081. A rotating motor 3083 is installed in the power tank opened in the incubator 1 to drive the rotating shaft 3082 to rotate. When supplying liquid or observing, the rotating motor 3083 is started to drive the rotating shaft 3082 to rotate, thereby driving the base plate 3081 to rotate, and then driving the culture tray 2 to rotate to supply liquid to the different culture dishes on it.

[0030] The incubator 1 has symmetrical ventilation ports 401 on both the left and right sides. A dust filter 402 is installed inside the ventilation port 401. The ventilation port 401 allows the air inside the incubator 1 to interact with the outside air. The dust filter 402 prevents a large amount of dust from entering the interior of the incubator 1 and affecting the growth of microorganisms.

[0031] The incubator 1 is equipped with a controller 5, and the uniform liquid supply mechanism 3 is electrically connected to the controller 5. The controller 5 is used to control the temperature inside the culture dish and to control the uniform liquid supply to the culture dish.

[0032] Example 2

[0033] Based on Example 1, such as Figures 1-5 As shown, long-term static storage of the culture medium in the supply tank 301 may lead to sedimentation, resulting in uneven nutrient distribution and affecting the observation of microbial growth. Therefore, the device also includes a mixing component 309. The mixing component 309 includes a rotating shaft 3091 rotatably connected to the supply tank 301. U-shaped mixing rods 3092 are vertically and equidistantly mounted on the rotating shaft 3091. A rotating cylinder 3093 is rotatably connected to the U-shaped mixing rods 3092. Stirring plates 3094 are equidistantly mounted in a ring on the rotating cylinder 3093, and the stirring plates 3094 are uniformly perforated with cutting holes. A drive rotating shaft 3091 is installed on the supply tank 301. The drive motor 3095, after standing for a period of time and before supplying liquid, is started to drive the rotating shaft 3091 to rotate, which in turn drives the U-shaped mixing rod 3092 on the rotating shaft 3091 to rotate and mix the culture medium in the supply tank 301, avoiding precipitation of the culture medium and uneven distribution of nutrients. As the rotating shaft 3091 rotates, the stirring plate 3094 on it collides with the liquid flow, thereby driving the rotating drum 3093 to rotate on the U-shaped mixing rod 3092. The cutting holes on the stirring plate 3094 cut and turbulent the liquid flow, thereby further improving the mixing efficiency.
