Description

Technical Field

[0001] This article relates to an automated strain culture device with synergistic control of light and humidity. Background Technology

[0002] In agricultural production, beneficial bacteria in the soil play a vital role in the growth and development of field crops such as rice and wheat. They can promote nutrient absorption and inhibit the growth of pathogens. Therefore, screening and cultivating beneficial bacteria from the soil that are adapted to the field environment, have strong vitality, and meet the growth conditions of crops is of great significance for improving crop yield and quality.

[0003] Currently, there are many types of devices used for strain screening and cultivation, but these devices have certain shortcomings in simulating the field environment. Existing devices often operate independently in terms of light and humidity control, making it difficult to achieve synergistic coordination between the two. However, in the field environment, light and humidity are dynamic and mutually influential. For example, on sunny days, light intensity is high and soil moisture is relatively low; on cloudy days or after rain, light intensity is weak and soil moisture is relatively high. Because existing devices cannot accurately simulate this dynamic and coordinated change in light and humidity in the field environment, the screened strains exhibit poor adaptability and weak vitality in actual field environments, making it difficult to meet the growth requirements of crops such as rice.

[0004] Therefore, there is an urgent need for an automated cultivation device that can achieve coordinated control of light and humidity, accurately mimic the field living environment, and thus screen out beneficial strains with strong vitality that meet the living conditions of field crops such as rice. Summary of the Invention

[0005] This invention aims to provide an automated bacterial culture device that can simulate the ecological environment of a field and has the function of synergistic regulation of light and humidity, thereby screening out strains with stronger adaptability. The specific structural scheme is as follows:

[0006] An automated strain cultivation device with coordinated control of light and humidity includes a main frame, and the main frame contains several independent cultivation units.

[0007] The culture unit includes a main frame and a removable part. The main frame includes an automated electrical control box, an atomizer, and a support frame. The shape of the top of the support frame matches the shape of the bottom of the removable part.

[0008] The removable part includes a semi-circular culture container and a square head. The side of the semi-circular culture container is provided with micropores, which are connected to the nebulizer through a conduit. The upper surface of the square head is provided with a photoresistor, which is connected to the nebulizer and the automated electrical control box through a circuit.

[0009] Furthermore, the main frame includes a top cover, a bottom plate, side plates, and a back plate, which together enclose a well-sealed overall space, providing a stable operating environment for the internal culture units.

[0010] The lower surface of the cover is equipped with independent light groups that match the number of culture units. Each independent light group can independently adjust the light intensity, light duration and spectrum type, which can provide specific light conditions for the corresponding culture units, meet the different light environment requirements of different strains, and lay the foundation for subsequent coordinated control of light and humidity.

[0011] Furthermore, the rated resistor R1 is connected in series with the atomizer and then in parallel with the photoresistor. The entire parallel circuit is then connected in series with the rated resistor R2 and connected to the constant voltage circuit, forming a complete working loop. When the light intensity changes, the resistance of the photoresistor changes accordingly, which in turn causes a change in the total resistance of the parallel section. Through the relationship between current and resistance in the series circuit, the operating current of the atomizer is ultimately adjusted, thereby dynamically changing the power of the atomizer and achieving coordinated operation between light and humidity.

[0012] Furthermore, the top of the support frame is provided with two long grooves on the left and right, and the inside of the long grooves is provided with cavities, the opening of the cavities abutting against the side wall of the semi-circular culture container.

[0013] When the nebulizer is working, the water mist generated in the nebulizer flows into the cavity of the long groove along the left guide tube, and then passes through the micropores on the side wall of the semi-circular culture container and enters the interior of the semi-circular culture container.

[0014] The liquid water accumulated in the long trough flows back to the water tank of the atomizer through the right conduit, realizing the recycling of water resources. This not only ensures the stability of humidity control, but also improves the energy efficiency and environmental friendliness of the device.

[0015] Furthermore, the cross-section of the semi-circular culture container is semi-circular. This structure facilitates the uniform spreading of the internal culture medium and reduces the waste of corner space, ensuring the consistency of light and humidity conditions for the strains during the culture process.

[0016] The square head has a square cross-section, and its shape is designed to match the interface of the main frame, ensuring precise alignment and stable fixation when the removable part is inserted into the main frame. Furthermore, the square head has an embedded handle, which does not affect the overall sealing while allowing operators to easily pull out the culture container, facilitating inoculation, observation, and sampling of bacterial strains, thus improving the ease of operation of the device.

[0017] Furthermore, the square head has electrical contacts on its side, and the main frame of the culture unit has matching metal plates. When the electrical contacts contact the metal plates, the circuit between the automated control box and the nebulizer is connected. This design not only enables rapid circuit connection without additional wiring, but also automatically disconnects the circuit when the culture container is removed, ensuring the safety of the operation process, while also guaranteeing the stability and reliability of the circuit connection.

[0018] When the photoresistor is connected in the circuit, the total resistance of the circuit is +R2, the voltage across the atomizer is As the light intensity increases, As the value of the atomizer gradually decreases, the total resistance of the parallel circuit decreases, the voltage across the atomizer gradually decreases, and thus the power of the atomizer gradually decreases.

[0019] Furthermore, the number of culture units is six.

[0020] Furthermore, a corresponding water tank door is provided below the cultivation unit, through which water can be added to the water tank of the nebulizer. The water tank door adopts an openable structure, which not only ensures the sealing of the internal structure of the device but also facilitates the operator's water tank filling operation. When the water level in the nebulizer tank is low, the operator only needs to open the water tank door below the corresponding cultivation unit to directly add water to the tank without disassembling the cultivation unit or interrupting the experiment.

[0021] Furthermore, the automated electrical control box is powered by a battery or AC power.

[0022] Furthermore, the semi-circular culture container has 12 micropores on one side. These 12 micropores ensure that water mist is evenly diffused within the container, maintaining consistent humidity in different areas and providing a stable growth environment for the strain.

[0023] Working principle:

[0024] Place the bacterial culture and culture medium in the semi-circular culture container of the removable unit, and then insert the removable unit into the main frame. At this time, the electrical contacts contact the metal plate, and the entire circuit is connected.

[0025] First, driven by the automated electrical control box, the atomizer starts working, and the water mist generated by atomization enters the interior of the semi-circular culture container along the conduit, long groove, and micropores.

[0026] At the same time, the photoresistor begins to receive light from the independent light group. When the light from the independent light group is large, it is necessary to simulate a long drought scenario. The resistance of the photoresistor decreases, which reduces the power of the atomizer.

[0027] When the lights of the independent light group are adjusted to a dim state, it is necessary to simulate the rainy season, which increases the resistance of the photoresistor and thus increases the power of the atomizer.

[0028] This enables the coordinated control of light intensity and humidity, thereby meeting the requirements for screening soil microbial strains and conducting natural simulation cultivation experiments.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. Achieve coordinated control of light and humidity: By sensing changes in light intensity through a photoresistor, the power of the atomizer is adjusted in real time to accurately simulate the dynamic relationship between light and humidity in the field environment (such as strong light and low humidity, weak light and high humidity), thus solving the problem of independent control in existing devices.

[0031] 2. Improved accuracy of strain adaptability screening: Because the simulated environment is closer to the actual field conditions, the screened strains are more adaptable and vigorous in the natural environment, better meeting the growth needs of crops. Furthermore, the device automatically controls light and humidity through circuitry, reducing manual intervention and improving cultivation efficiency and stability. Attached Figure Description

[0040] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0041] Example 1: As Figure 1-6 As shown, an automated strain culture device with coordinated control of light and humidity has a main frame consisting of an upper cover 1, a bottom plate 6, a side plate 5 and a back plate 4, and is equipped with 6 independent culture units inside.

[0042] The main frame of each culture unit includes an automated electrical control box 9, an atomizer 10, and a support frame 8. The top of the support frame 8 has two long slots 11 with cavities on the left and right, and the cavity openings abut against the side wall of the semi-circular culture container 7. The removable part consists of the semi-circular culture container 7 (with 12 micro-holes 13 on one side) and a square head 2. The square head 2 is fitted with a handle 16, and a photoresistor 15 is provided on the upper surface, with electrical contacts 14 at both ends.

[0043] During assembly, the removable part is inserted into the main frame, and the electrical contact 14 contacts the metal plate of the main frame, thus connecting the circuit. Water is added to the water tank of the atomizer 10 through the water tank door 3. The automatic electrical control box 9 is powered by AC power.

[0044] During operation, the automated control box 9 starts the atomizer 10, and the water mist enters the culture container through the left conduit 12, the cavity of the long groove 11, and the micropores 13; excess liquid water flows back to the water tank through the right conduit 12.

[0045] like Figure 7 As shown, one end of the electrical contact is point A, and the other end is point B. When the removable part is pulled out, the entire circuit is disconnected; when the removable part is inserted, the entire circuit is connected. Furthermore, as the illumination of the independent lamp group changes, the resistance of the photoresistor 15 changes accordingly: the resistance decreases under strong light, the total parallel resistance decreases, and the power of the atomizer 10 decreases (simulating prolonged drought).

[0046] Under low light, the resistance increases, the total parallel resistance increases, the voltage across the atomizer 10 increases, and the power of the atomizer 10 increases (simulating the rainy season), thus achieving coordinated control of light and humidity.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
