Description

Technical Field

[0001] This utility model relates to an algae cultivation and display cabinet, specifically a cabinet for the breeding and propagation of Noctiluca scintillans. Background Technology

[0002] Noctiluca scintillans, commonly known as "blue tears," is highly valued for its bioluminescent properties and is cultivated and propagated in many aquariums and biology museums for ornamental purposes. The bioluminescence of Noctiluca scintillans is primarily based on the biochemical reaction of the luciferin-luciferase system. The core process is that when cells are stimulated externally, luciferin combines with oxygen under the catalysis of luciferase, releasing energy and transforming into blue-green fluorescence. Because the bioluminescence of Noctiluca scintillans requires external stimulation, current display cases typically incorporate water agitation to stimulate bioluminescence. However, controlling the agitation is difficult, and after each agitation, the algae require a long wait before luminescence resumes, which visitors cannot tolerate, resulting in a less than ideal viewing experience. Currently, there is no publicly available solution to this problem, and improvements to existing methods of stimulating Noctiluca scintillans bioluminescence are needed. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a display cabinet for the breeding and propagation of *Noctiluca scintillans*, thereby solving the technical problems of existing *Noctiluca scintillans* display cabinets, such as short duration and inconsistent intervals of luminescence, which affect the viewing effect. This objective is achieved through the following technical solution.

[0004] A display cabinet for the cultivation and propagation of *Noctiluca scintillans* is disclosed. The cabinet includes a frame and a transparent display tank. The frame is cubical, and the display tank is located in the center. The key structural feature is that the top of the display tank is open. A lighting fixture and a dripping device are fixedly installed on the top of the frame. The dripping device includes a storage tank, a pump, and a dripping head. The dripping nozzle of the dripping head corresponds to the open surface of the top of the display tank. The dripping head is connected to the outlet of the pump via a pipe, and the inlet of the pump is connected to the storage tank via a pipe. This structure utilizes dripping stimulation instead of the existing water agitation method, making it easier to control the intensity of the stimulation and maintain continuous localized bioluminescence of the *Noctiluca scintillans*, achieving a continuous viewing effect without long waiting times, resulting in better visual appeal. Furthermore, the lighting facilitates the cultivation and propagation of *Noctiluca scintillans*, allowing the display tank to also function as a culture tank.

[0005] The top of the cabinet forms a mounting cavity, and the lighting, pump, and drip head are all fixed to the bottom plate of the mounting cavity. A hook is provided on one side of the liquid storage tank, which is then suspended from the hanging rod at the rear of the cabinet. This structure serves as the specific installation implementation for the lighting and drip device. The liquid storage tank adopts a hanging structure, making it easy to remove and replenish the liquid at any time, and is relatively convenient to operate and use.

[0006] The pump is a peristaltic pump. This design allows the peristaltic pump to have better metering capabilities, making it easier to control the liquid output from the drip head.

[0007] The bottom of the display tank forms an inverted cone-shaped sedimentation chamber, and a drain pipe with a valve is installed at the bottom of the sedimentation chamber. This structure facilitates the replacement or cleaning of the algae solution in the display tank.

[0008] A magnet lamp is fixed to the cabinet on one side of the sedimentation chamber. This structure allows the magnet lamp to attract impurity organisms. While Noctiluca scintillans is being cultivated in the display tank for a long time, other organisms will grow. By utilizing the phototaxis of these other organisms, impurity organisms can be gathered in the sedimentation chamber and then discharged in time when the drain valve is opened, ensuring that the environment in the display tank is suitable for the growth of Noctiluca scintillans.

[0009] This invention uses a dripping method to stimulate Noctiluca scintillans. Compared with existing methods of stimulating water by agitation, it is easier to control the intensity of stimulation and the stimulation range is smaller. This allows for localized and continuous luminescence of Noctiluca scintillans in the display tank, achieving continuous viewing without the need for long waiting times. The viewing effect is better and it is suitable for use as a Noctiluca scintillans display cabinet and aquaculture cabinet, or as an improvement on the structure of similar display cabinets.

[0013] The present invention will now be further described with reference to the accompanying drawings.

[0014] like Figure 1 , Figure 2As shown, the Noctiluca scintillans breeding and display cabinet includes a cabinet frame 1, a display tank 2, a lighting lamp 5, and a dripping device. The cabinet frame has a cubic frame structure, with a transparent display tank supported in the middle. The top of the display tank is open. The top of the cabinet frame forms an installation cavity 4, with the front and sides of the installation cavity covered by baffles, and the bottom forming a base plate. The installation cavity is equipped with a lighting lamp 5 and a dripping device. Specifically, there are one or more lighting lamps, which are fixed to the base plate. The dripping device includes a storage tank 8, a pump 7, and a dripping head. The pump is a peristaltic pump, and the dripping nozzle of the dripping head corresponds to the open surface of the display tank, meaning that the dripping head drips into the open surface of the display tank. The dripping head is connected to the outlet of the peristaltic pump through a pipe, and the inlet of the peristaltic pump is connected to the storage tank through a pipe. A hook 801 is provided on one side of the storage tank, and the tank is suspended from the hanging rod 9 at the rear of the cabinet frame near the installation cavity, thus facilitating the removal, placement, and water changing of the storage tank. The aforementioned lighting and peristaltic pump are powered by batteries or by connecting to an external mains power source.

[0015] The bottom of the aforementioned display tank 2 forms an inverted cone-shaped sedimentation chamber 201, with a drain pipe 3 equipped with a valve at the bottom. A magnet 10, fixed to a cabinet frame, is located on one side of the sedimentation chamber. Utilizing the phototaxis of impurity organisms, turning on the magnet facilitates the concentration of these organisms within the sedimentation chamber. When the drain pipe is opened, the impurities and sediment are discharged together, ensuring a suitable growth environment for the *Noctiluca scintillans* and promoting its breeding and propagation. The magnet is powered by either a battery or external AC power.

[0016] This Noctiluca scintillans breeding and display cabinet serves a dual function of cultivation and display. When used for cultivation, the lighting facilitates the growth of the Noctiluca scintillans, while the sedimentation chamber and drain pipe at the bottom of the display tank allow for easy cleaning and liquid changes. When used as a display cabinet, the lighting is turned off, and the dripping device is activated. The device is set to automatically drip liquid at regular intervals (e.g., one minute). Each drop stimulates specific areas of the Noctiluca scintillans within the display tank, causing them to glow and achieving the desired display effect. Because the Noctiluca scintillans is constantly moving, each drip stimulates different areas, resulting in continuous glowing without waiting, and providing excellent display results.

[0017] The above description is intended to illustrate the technical means of this utility model and is not intended to limit the technical scope of this utility model. Any obvious improvements or substitutions made to this utility model by those skilled in the art based on existing common knowledge also fall within the protection scope of the claims of this utility model.
