Abstract
Description
Technical Field
[0001] This utility model relates to the field of incubator technology, and in particular to an incubator that can adjust the angle of the culture medium. Background Technology
[0002] Microbial culture is a crucial technique in fields such as biomedicine, food testing, and environmental monitoring. In traditional microbial culture, slant agar media is widely used due to its advantages, including increased surface area and ease of bacterial inoculation and observation. However, in current techniques, the observation of bacterial growth on slant agar media relies entirely on manual operation. Researchers must remove each culture tube daily and observe for bacterial growth with the naked eye or a microscope, repeating this process until bacterial growth is observed or the longest negative growth cycle is reached. This traditional observation method is labor-intensive and inefficient; when testing large batches of samples, researchers must repeatedly perform the monotonous process of removing, observing, and replacing the tubes.
[0003] Meanwhile, existing incubators typically use fans or airflow circulation systems to maintain a uniform distribution of CO2 concentration and temperature within the chamber. While this traditional airflow circulation method can improve environmental uniformity to some extent, it also brings significant side effects:
[0004] (1) Increased evaporation of culture medium: The airflow generated by the fan creates forced convection on the surface of the petri dish, significantly accelerating the evaporation process of water in the culture medium. According to mass transfer theory, the evaporation rate under forced convection conditions is much higher than that under natural convection conditions. This accelerated evaporation not only affects the concentration stability of the culture medium but may also change the nutrient composition ratio of the culture medium;
[0005] (2) Uneven evaporation: The air velocity is higher near the fan, resulting in a significantly higher evaporation rate of the culture medium in this area compared to areas further away from the fan. This leads to differences in the moisture content of the culture medium at different locations within the chamber. This uneven evaporation pattern causes inconsistencies in the culture environment and affects the reproducibility of experimental results.
[0006] (3) Increased consumption of culture medium: In order to maintain the appropriate liquid level and concentration of the culture medium, it is necessary to add culture medium frequently, which not only increases the experimental cost and operational complexity, but may also introduce the risk of contamination during the replenishment process.
[0007] Therefore, existing technologies lack a comprehensive technical solution that can achieve uniform distribution of environmental parameters within the incubator, effectively control culture medium evaporation, and improve the efficiency of culture medium observation. Based on this, this invention designs an incubator with adjustable culture medium angle to solve the aforementioned problems. Utility Model Content
[0008] The purpose of this invention is to provide an incubator with an adjustable culture medium angle. This device adds a swivel joint and a slide rail, and uses these to mount the culture rack. Test tube slots are provided on the side of the culture rack to hold test tubes, and these slots are arranged in a straight line. The culture rack can be completely slid out of the culture chamber via the slide rail, allowing personnel to directly observe the culture medium inside the test tube slots from the side, eliminating the need to remove each tube individually. This greatly simplifies operation, especially when culturing a large number of samples simultaneously. The ability to remove the culture rack allows for simultaneous observation of bacterial growth on the entire row of slant culture media, improving work efficiency. Furthermore, this device can be adapted to various sizes of slant culture media test tubes by changing the culture rack, and the tilt angle of the culture rack can be adjusted via the swivel joint to meet the environmental requirements of bacteria at different growth stages.
[0009] This invention is achieved as follows: an incubator capable of adjusting the angle of the culture medium, comprising:
[0010] Box body, diverter joint, slide rail, culture rack and flow guide device;

[0012] The steering joint is a universal ball joint. Multiple slide rails are arranged in the culture chamber along the front-back direction. Multiple steering joints are evenly arranged at the bottom of each slide rail. The steering joints arranged on the same slide rail are all distributed in a straight line along the front-back direction.
[0013] Each of the slide rails is rotatably locked inside the culture chamber via a steering joint;
[0014] Each adjacent slide rail does not contact each other;
[0015] The culture rack is a vertical flat plate structure, and multiple test tube slots are opened on one vertical side wall of the culture rack. The multiple test tube slots are arranged in a straight line along the front-back direction.
[0016] Each of the slide rails is provided with a groove at the top, and a culture rack can be detachably slid in each of the slide rails;
[0017] The flow guiding device includes a flow guiding ball and a flow guiding rod. The flow guiding ball is a sphere, and the flow guiding rod is a cylinder. The flow guiding rod is provided at both the upper and lower ends of the flow guiding ball. Two flow guiding balls and three flow guiding rods are vertically connected in sequence at intervals to form an integral structure. The axes of each flow guiding ball and each flow guiding rod coincide.
[0018] The outer wall of each of the aforementioned guide balls and each guide rod is recessed inward to form a guide groove, which is a spiral groove.
[0019] A motor is installed at the upper end of the flow guiding device, and a bearing seat is installed at the lower end of the flow guiding device. The flow guiding device is rotatably installed in the culture chamber via the motor and the bearing seat, and the rotation axis of the flow guiding device is vertically set.
[0020] Furthermore, a partition is horizontally arranged inside the culture chamber. The partition is a flat plate and is horizontally positioned on the horizontal central axis surface of the culture chamber.
[0021] The culture chamber is divided into upper and lower layers by a partition;
[0022] Multiple slide rails are also provided on the partition along the front-to-back direction, and the slide rails are rotatably mounted on the top of the partition via a steering joint;
[0023] The slide rails on the partition have the same direction and structure as the slide rails at the bottom of the culture chamber, and a culture rack is also installed on the top of the partition via slide rails.
[0024] Furthermore, the culture rack has multiple replacement parts, and the test tube slots of the replacement parts of the culture rack have multiple different diameters;
[0025] The test tube trough is a vertically arranged U-shaped tube clamp, and the test tube trough has an opening in the vertical side wall of the culture rack.
[0026] Furthermore, the chamber is an intelligent water-jacketed incubator, with a controller installed on the outside of the chamber, the motor connected to the controller, and the motor located inside the chamber.
[0027] Furthermore, the culture rack is slidably installed in the trough along the front-back direction, the trough has openings at the top and front, and the trough is a dovetail groove; the axis of the slide rail and the axis of the trough in the front-back direction coincide.
[0028] The beneficial effects of this utility model are: 1. This utility model adds a slide rail, and the slide rail allows the culture rack to slide out horizontally out of the culture chamber, which makes it easier for personnel to observe the culture medium in the test tube from the side. There is no need to take out the test tube, and there is no need to perform individual pick-up and put-down operations. After observation, the entire culture rack can be pushed back into the culture chamber, which simplifies the operation process and effectively improves the observation efficiency.
[0029] 2. The front end of the chute of this device is open, and the culture rack can slide out of the front end of the chute for easy replacement. It can also be equipped with culture racks of different sizes of test tubes to accommodate culture medium test tubes of different sizes.
[0030] 3. This device also includes a swivel joint, which allows the slide to be tilted and the angle of the slide to be adjusted at any angle. This allows the culture rack to be rotated and the culture medium tubes loaded on it to be rotated and adjusted accordingly. This makes it easy to change the placement angle of the culture medium tubes and adjust the contact surface of the sample on the slanted surface of the culture medium. The operation is convenient and simple. Moreover, the culture rack tilted to the left and right does not obstruct the observation surface of the culture medium.
[0031] 4. The flow guiding device can turbulent the gas in the culture chamber. This device does not use fans or blowing air, which effectively prevents the culture medium near the air vent from drying out too quickly. In addition, the rotating flow guiding device can make carbon dioxide evenly distributed in the culture chamber, so that the growth environment of each culture medium is kept as similar as possible.

[0043] Please see Figures 1 to 8 As shown, this utility model provides an incubator that can adjust the angle of the culture medium. In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0044] In a specific embodiment of the technical solution of this utility model:
[0045] Includes box body 1, diverter 2, culture rack 3, and flow guiding device;
[0046] The box body 1 is a sealed shell, and the inside of the box body 1 is a hollow culture chamber 12. A sealed door 11 is provided on the front of the box body 1. The sealed door 11 is sealed and closed on the front of the box body 1 by a hinge, and can also be opened easily. The edge of the sealed door 11 is provided with sealant, and its structure is the same as that of a refrigerator door, so that it can remain sealed after being closed.
[0047] The swivel joint 2 is a universal ball joint, which can be the universal ball on a mobile phone holder. This design allows the connecting components to freely adjust their connection relationship at different angles and directions, thereby meeting diverse support needs. The universal ball joint design enables the holder to rotate 360 degrees.
[0048] Multiple slide rails 21 are arranged along the front-to-back direction inside the culture chamber 12. Multiple deflector joints 2 are evenly distributed at the bottom of each slide rail 21. The deflector joints 2 on the same slide rail 21 are all arranged in a straight line along the front-to-back direction, allowing adjustment of the angle of the locked slide rail 21 via the deflector joints, enabling the slide rail 21 to rotate or deflect to the left or right. The deflector joints 2 do not contact each other, and the planes on which each deflector joint 2 is located are parallel to each other.
[0049] Each slide rail 21 is rotated and locked inside the culture chamber 12 via the diverter joint 2;
[0050] Each adjacent slide rail 21 does not contact each other. Each slide rail 21 is locked onto the diverter joint 2 in the front-to-back direction and is vertically distributed in the front-to-back direction. Each slide rail 21 is parallel to each other.
[0051] Multiple swivel joints 2 are grouped together. Multiple swivel joints 2 are provided at the bottom of the culture chamber 12 and the top of the partition 22. Each group of swivel joints 2 is fixedly clamped on the bottom plane of the culture chamber 12 or the top of the partition 22 in the front-back direction. They are all evenly distributed in a straight line in the front-back direction. Each slide rail 21 is mounted on the top of the same group of swivel joints 2, so that the slide rail 21 can be adjusted and swung in the left-right direction.
[0052] The straight lines of each set of swivel joints 2 are parallel to each other, that is, to ensure that the front and rear axes of each slide rail 21 are set parallel to each other.
[0053] The culture rack 3 is installed in the top slide groove 23 of the slide rail 21. After the sealing door 11 is opened, the culture rack 3 can slide forward along the slide groove 23 to the outside of the box 1 for easy viewing of the culture medium.
[0054] The culture chamber 12 is also horizontally equipped with a partition 22. The partition 22 is horizontally positioned at the middle height of the culture chamber 12 along the front-to-back direction. The partition 22 is horizontally positioned on the horizontal central axis of the culture chamber 12, and the culture chamber 12 is divided into upper and lower layers by the partition 22. There are two layers of culture racks 3 in the culture chamber 12. The two layers of culture racks 3 are arranged to facilitate the placement of more slant culture media and improve the efficiency of culturing strains.
[0055] Multiple slide rails 21 are also provided on the partition 22 along the front-to-back direction. The slide rails 21 are also rotatably mounted on the top of the partition 22 via the steering joint 2.
[0056] The slide rail 21 on the partition 22 has the same direction and structure as the slide rail 21 at the bottom of the inner cavity of the culture chamber 12, and the culture rack 3 is also installed on the top of the partition 22 via the slide rail 21. Therefore, the slide rail 21 on the top of the partition 22 can also be adjusted to the left or right via the deflector joint 2.
[0057] Each slide rail 21 has a groove 23 with openings at the top and front. A culture rack 3 slides within the groove 23 at the top of each slide rail 21 in the front-to-back direction. The culture rack 3 can slide out from the front opening of the groove 23. A smooth mating friction surface, such as the mating surface of a sliding bearing, can be provided within the groove 23 at the top of the slide rail 21. The culture rack 3 and the groove 23 can have a transitional fit. Furthermore, the front opening of the groove 23 at the top of each slide rail 21 is narrower, meaning the very front opening of the groove 23 is narrower, providing a transitional fit with the slide rail 21. The normal portion of the groove 23 also has a transitional fit with the slide rail 21 and is provided with a smooth mating surface. In other words, the inner side of the groove 23 needs to slide smoothly, while the outer side is narrower, making it more difficult for the culture rack 3 to slide out of the groove 23, but allowing for smoother sliding within.
[0058] The culture rack 3 of this device can slide on the groove 23 at the top of the slide rail 21. The front end of the groove 23 is open, and the culture rack 3 can also slide out from the front opening of the groove 23 for replacement. Different models of the culture rack 3 are also available to match different sizes of slant culture medium test tubes.
[0059] The culture rack 3 is a vertical flat plate structure. Multiple test tube slots 31 are opened on one vertical side wall of the culture rack 3. The multiple test tube slots 31 are arranged in a straight line along the front and back direction. The culture rack 3 has multiple replacement parts. The test tube slots 31 of the replacement parts of the culture rack 3 have multiple different diameters. The test tube slots 31 are vertically set U-shaped tube clamps. The test tube slots 31 are opened on the vertical side wall of the culture rack 3.
[0060] The culture rack 3, through the adjustment of the slide rail 21 and the deflection joint 2, allows the slide rail 21 to tilt to the left or right. The culture rack 3 is then locked in the slide groove 23, tilting along with the slide rail 21. This tilts the culture medium test tubes inside the culture rack 3, exposing the left side of the test tube slot 31 for easy observation of bacterial growth on the culture medium from the front. Since the test tube slot 31 of this device opens to the left, the slide rail 21 is adjusted to tilt the culture medium to the right, allowing direct observation of bacterial growth on the slant surface of the culture medium from the test tube slot 31. Furthermore, the entire culture rack 3 is tilted, allowing the slide groove 23 to be directly pulled out, facilitating direct observation of the culture medium test tubes from outside the incubator 1, eliminating the need to remove each test tube individually and significantly improving work efficiency.
[0061] The flow guiding device includes a flow guiding ball 4 and a flow guiding rod 43. The flow guiding ball 4 is a sphere, and the flow guiding rod 43 is a cylinder. The flow guiding rod 43 is provided at both the upper and lower ends of the flow guiding ball 4. Two flow guiding balls 4 and three flow guiding rods 43 are vertically connected in sequence at intervals to form an integral structure. The axes of each flow guiding ball 4 and each flow guiding rod 43 coincide.
[0062] Each guide ball 4 and each guide rod 43 has an inwardly recessed guide groove 41 on its outer wall, and the guide groove 41 is a spiral groove.
[0063] A motor 42 is installed at the upper end of the flow guiding device, and a bearing seat 44 is installed at the lower end of the flow guiding device. The flow guiding device is rotatably installed in the culture chamber 12 via the motor 42 and the bearing seat 44, and the rotation axis of the flow guiding device is set vertically.
[0064] The inner cavity of the chamber 1 of this device does not require an air vent, which is a characteristic of this device. If air were blown, it would generate a significant airflow, causing the culture medium near the air to dry too quickly. This device does not blow air; it only uses a flow guiding device to agitate the air inside the culture chamber 12, ensuring that the various gas components are evenly distributed within the culture chamber 12, but no significant airflow is generated within the culture chamber 12.
[0065] The rotating outer wall of the flow guiding device will disturb the inside of the culture chamber 12 to form a vortex flow. Through the speed difference and the different diameters of the flow guiding ball 4 and the flow guiding rod 43, the gas is disturbed and stirred. Furthermore, the concave flow guiding groove 41 on its surface will further disturb the airflow, causing the airflow to circulate along the inside of the culture chamber 12, but without forming an airflow. This is gentler and more stable, while also being able to evenly disperse carbon dioxide within the culture chamber 12.
[0066] The chamber 1 is an intelligent water-jacketed incubator. A controller 13 is installed on the outside of the chamber 1. The motor 42 is connected to the controller 13. The motor 42 is located inside the chamber 1, but not inside the culture chamber 12. The controller controls the rotation speed and direction of the motor 42, as well as the temperature, humidity, carbon dioxide inlet and outlet, humidity sensor, and temperature sensor. This allows the chamber 1 to maintain constant temperature and humidity, and the CO2 level to remain constant. This keeps the environment inside the culture chamber 12 constant. This structure is commonly used in water-jacketed incubators.
[0067] It should be noted that:
[0068] 1. In bacterial culture, the growth of bacteria on slant culture media needs to be observed daily. The current procedure involves removing each culture tube, observing it, and then placing it back into the tube rack. While the operation of a single culture tube is not difficult, once the quantity reaches a certain level, the entire observation process consumes a significant amount of time. Optimizing even a small step can greatly reduce the number of repetitive operations. This device optimizes the operation of removing and placing culture tubes, simplifying the observation process. The entire observation process involves only removing the culture rack 3 and pushing it back in, greatly simplifying the entire observation process and effectively improving inspection efficiency.
[0069] 2. This device can adjust the angle of the test tube and its internal culture medium, allowing the culture medium to be adjusted to different angles at different stages of cultivation, which is impossible with existing equipment. This device can adjust the angle for cultivation at different stages, especially in the early stages of cultivation, by tilting the culture medium. The tilted position allows the inoculated bacteria to flow and spread slowly along the slant of the culture medium under the action of gravity, which is conducive to the uniform distribution and growth of bacteria on the entire slant of the culture medium. This is something that vertically placed culture medium cannot achieve.
[0070] 3. Existing incubators use fans to mix various gas components inside, which leads to uneven drying of culture medium tubes near and far from the fan, making it difficult to maintain a consistent growth environment for bacteria. This device, however, uses a gourd-like structure of guide balls 4 and guide rods 43. Based on the Magnus effect, the rotation of this guide device agitates the air without needing to blow air into the culture chamber 12, ensuring uniform mixing of the various gas components.
[0071] When using this invention, bacteria are inoculated by placing the culture medium test tubes one by one in the test tube trough 31. Test tubes of the same batch and model are placed in the same culture rack 3, and strains of the same type are also placed in the same culture rack 3 as much as possible. Labels can be affixed to the test tubes for differentiation. The labels should not obstruct the observation area of the culture medium on the test tubes.
[0072] In the initial stage of inoculation of the culture medium strain, the culture medium needs to be tilted to facilitate its growth. The culture rack 3 containing the culture medium test tubes is placed in the groove 23 at the top of the slide rail 21 and in the deflector 2. The deflector 2 is adjusted to tilt the slide rail 21 to the left or right, so that the culture medium is also tilted, allowing for better contact with the strain for cultivation. The culture medium should be tilted at a certain angle, generally 45°-60°, so that the bacteria can more easily flow and spread on the slant of the culture medium under the action of gravity.
[0073] After a period of cultivation, usually about a week, adjust the culture rack 3, slide rail 21 and deflector joint 2 to make the top plane of slide rail 21 level and the culture rack 3 vertical, so that the culture medium test tubes are also adjusted to a vertical state, and proceed to the next stage of cultivation.
[0074] When observing the slant culture medium, simply pull out the entire culture rack 3 along the slide rail 21 and observe the culture medium inside the test tubes through the opening of the test tube slot 31. No other operations are required, and personnel can directly inspect the culture medium in the entire row of test tubes. After inspection, if it is necessary to operate on a particular slant culture medium, simply remove the individual test tube for operation. If no additional operation is required, simply push the entire row of culture racks 3 back into the culture chamber 12 along the slide rail 21.
[0075] The main reasons for keeping the slanted culture medium at an incline for a period of time after inoculation, about one week, before switching it to an upright position are:
[0076] 1. Promotes initial growth and spread: The tilted position allows the inoculated bacteria to flow and spread slowly along the slant of the culture medium under the action of gravity, which is conducive to the uniform distribution and growth of bacteria on the entire slant of the culture medium.
[0077] 2. Prevent excessive moisture at the bottom of the culture medium: In the early stage of bacterial inoculation, keep the test tube tilted so that the condensed water can flow down the slope without soaking the culture medium, forming a shallower water layer. This effectively avoids excessive water accumulation at the bottom of the culture medium, preventing contamination and the washing away of bacteria by the water.
[0078] 3. Optimize oxygen supply: The tilted position provides a larger gas-liquid contact area. When the test tube is placed vertically, only the inner diameter of the test tube is in contact with the liquid. However, when it is tilted, the greater the tilt, the larger the gas-liquid contact area, which is more conducive to the initial growth of aerobic bacteria.
[0079] 4. Controlling growth rate: After one week, the bacteria have stabilized and can be kept upright to slow down the growth rate, making it suitable for long-term preservation.
[0080] 5. Extended storage time: When the culture medium tube is upright, the bottom is thicker, which helps retain moisture for a longer time, thus extending the shelf life of the strain and preventing the culture medium from drying out too quickly.
[0081] This method of placing culture medium test tubes by tilting them first and then standing them upright combines the advantages of two different placement methods, ensuring good bacterial growth and facilitating long-term preservation.
