Description

Technical Field

[0001] This utility model relates to the technical field of Dendrobium cultivation equipment, specifically a constant temperature and humidity incubator for Dendrobium tissue culture seedlings. Background Technology

[0002] Dendrobium, a precious medicinal plant, is facing increasing scarcity in its wild population. Artificial tissue culture propagation has become a primary method for meeting market demand and protecting wild resources. During the tissue culture seedling cultivation process, the seedlings have extremely high requirements for parameters such as temperature, humidity, air cleanliness, and space utilization: the temperature must be stably maintained within a suitable range, humidity must be kept in a moist environment, and air circulation must be ensured to prevent dust and microbial contamination, thus avoiding problems such as browning, contamination, and slow growth.

[0003] However, the existing cultivation equipment used for Dendrobium tissue culture seedlings has many technical defects and cannot meet the above-mentioned precise cultivation requirements: First, the temperature and humidity control is uneven. Most culture boxes use a single heating element or humidification device, which makes it easy for heat to accumulate locally in the box, resulting in greater temperature differences between the upper and lower layers and the left and right sides. During the humidification process, the water mist is unevenly distributed, and excessive humidity in some areas leads to mold growth, while insufficient humidity in some areas causes water loss in the leaves of tissue culture seedlings.

[0004] In view of this, we propose a constant temperature and humidity incubator for Dendrobium tissue culture seedlings. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a constant temperature and humidity incubator for Dendrobium tissue culture seedlings.

[0006] The technical solution of this utility model is:

[0007] A constant temperature and humidity incubator for Dendrobium officinale tissue culture seedlings includes an incubator body. The incubator body is equipped with a temperature sensor and a humidity sensor. Two support frames are located inside the incubator body, with two support rods symmetrically fixed between them. A ring-shaped turntable is rotatably mounted on the top of each support frame. A heating box is mounted on the top of the incubator body, and a blower box is mounted on the top of the heating box. Several electric heating grids are installed inside the heating box. Several heat-conducting pipes arranged in a ring array are installed at the bottom of the heating box. Several exhaust holes are opened on the outer wall of the heat-conducting pipes. A water tank is fixedly installed on both sides of the incubator body. The water tanks are connected to an atomizer via water supply pipes. An inner tube extending into the interior of the incubator body is installed at the air outlet of the atomizer. Several equally spaced atomizing nozzles are installed on the outer wall of the inner tube. By incorporating a support frame and support rods with a ring-shaped turntable within the cultivation box, multi-angle cultivation of Dendrobium tissue culture seedlings can be achieved, improving space utilization. The heating box, combined with a ring-shaped array of heat-conducting pipes and exhaust vents, allows heat to be evenly distributed throughout the box, ensuring stable temperature. The water tanks on both sides, through atomizers, internal extension pipes, and atomizing nozzles, can evenly deliver water mist into the box, effectively maintaining humidity. The overall structure achieves coordinated control of constant temperature and humidity, providing a suitable growth environment for Dendrobium tissue culture seedlings.

[0008] As a preferred technical solution, the heat-conducting pipe passes through the upper support frame and extends to near the lower support frame. This extension of the heat transfer path allows for more efficient heat distribution to different height areas within the incubator, preventing excessive temperature differences between upper and lower layers and further improving the uniformity of temperature distribution within the incubator. This ensures that all Dendrobium tissue culture seedlings at different levels are in a stable temperature environment.

[0009] As a preferred technical solution, the incubation box body has two doors symmetrically hinged at the front, and each door is equipped with a door handle. The two doors and door handles symmetrically hinged at the front of the incubation box facilitate the operation of opening or closing the incubation box, and make it convenient for operators to observe, inoculate, and change the Dendrobium tissue culture seedlings inside.

[0010] As a preferred technical solution, a tank cover is installed on one side of the outer wall near the top of the water tank, and a drain pipe with a drain valve is installed at the bottom of the water tank. The tank cover at the top of the water tank facilitates the addition of water to the tank and prevents external impurities from entering and affecting the water quality; the drain pipe and drain valve at the bottom can promptly drain residual water or wastewater from the water tank, facilitating cleaning of the water tank.

[0011] As a preferred technical solution, a support block is fixedly installed at each of the four corners of the bottom of the lower support frame, and an air vent is provided at the bottom of the incubator body. The support legs at the bottom of the lower support frame can stably support the support frame and the upper structure.

[0012] As a preferred technical solution, a horizontal plate is fixedly installed inside the air blowing box. Several drive motors are mounted on the horizontal plate, and each drive motor's output shaft is coaxially fixed with a rotating shaft. A fan blade is coaxially fixed on the rotating shaft. The drive motors on the horizontal plate inside the air blowing box drive the fan blades to rotate, efficiently delivering external air or hot air from the heating chamber into the incubator, accelerating airflow and allowing the heat emitted by the heat pipes to diffuse more quickly throughout the chamber.

[0013] As a preferred technical solution, the top of the air blower is fixed to the top of the air blower by fixing bolts located at the four corners, and a protective filter screen is installed inside the mounting frame. This filter can filter the air entering the air blower, preventing dust, impurities, and microorganisms from entering the incubator.

[0014] As a preferred technical solution, a support leg is fixedly installed at each of the four corners of the bottom of the incubator body. The support legs at the four corners of the bottom of the incubator body can stably support the entire incubator on the ground, avoiding direct contact between the incubator body and the ground.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention enables multi-angle cultivation of Dendrobium tissue culture seedlings by setting a support frame and support rod with a ring turntable inside the cultivation box, thereby improving space utilization. The heating box, combined with the ring-shaped array of heat-conducting pipes and exhaust holes, allows heat to be evenly diffused to all areas inside the box, ensuring stable temperature. The water tanks on both sides can evenly deliver water mist into the box through atomizers, inner extension pipes, and atomizing nozzles, effectively maintaining humidity. The overall structure achieves coordinated control of constant temperature and humidity, providing a suitable growth environment for Dendrobium tissue culture seedlings. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0024] Please see Figures 1-4 This utility model provides a technical solution:

[0025] The constant temperature and humidity incubator for Dendrobium officinale seedling cultivation includes an incubator body 1. A temperature sensor 13 and a humidity sensor 14 are installed inside the incubator body 1. Two support frames 5 are provided inside the incubator body 1, with two support rods 50 symmetrically fixed between the two support frames 5. A ring-shaped turntable 52 is rotatably mounted on the top of each support frame 5. A heating box 3 is installed on the top of the incubator body 1, and a blower box 4 is installed on the top of the heating box 3. Several electric heating grids 30 are installed inside the heating box 3. Several heat-conducting pipes 31 arranged in a ring array are installed at the bottom of the heating box 3. Several exhaust holes 310 are opened on the outer wall of the heat-conducting pipes 31. A water tank 2 is fixedly installed on both sides of the incubator body 1. The water tank 2 is connected to an atomizer 22 through a water supply pipe 21. An inner extension pipe 25 extending into the interior of the incubator body 1 is installed at the outlet of the atomizer 22. Several equally spaced atomizing nozzles 26 are installed on the outer wall of the inner extension pipe 25. By setting a support frame 5 with a ring turntable 52 and a support rod 50 inside the cultivation box body 1, multi-angle cultivation of Dendrobium tissue culture seedlings can be realized, improving space utilization. The heating box 3, together with the heat-conducting pipes 31 distributed in a ring array and the exhaust port 310, can evenly diffuse heat to all areas inside the box, ensuring stable temperature. The water tanks 2 on both sides can evenly deliver water mist into the box through the atomizer 22, the inner extension pipe 25 and the atomizing nozzle 26, effectively maintaining humidity. The overall structure realizes the coordinated control of constant temperature and humidity, providing a suitable growth environment for Dendrobium tissue culture seedlings.

[0026] In a preferred embodiment, the heat pipe 31 passes through the upper support frame 5 and extends to a position near the lower support frame 5. By extending the heat pipe 31 through the upper support frame 5 and to a position near the lower support frame 5, the heat transfer path is lengthened, allowing for more efficient heat delivery to different height areas within the incubator. This avoids excessive temperature differences between the upper and lower layers, further improving the uniformity of temperature distribution within the incubator and ensuring that all Dendrobium tissue culture seedlings at different levels are in a stable temperature environment.

[0027] As a preferred embodiment, the incubation box body 1 has two doors 10 symmetrically hinged on the front side, and each door 10 is equipped with a door handle 11. The two doors 10 and the door handles 11 symmetrically hinged on the front side of the incubation box make it convenient for operators to open or close the incubation box, and facilitate the observation, inoculation, and replacement of the Dendrobium tissue culture seedlings inside.

[0028] In a preferred embodiment, a cover 20 is installed on one side of the outer wall of the water tank 2 near the top, and a drain pipe 23 is installed at the bottom of the water tank 2, with a drain valve 24 installed on the drain pipe 23. The cover 20 at the top of the water tank 2 facilitates the addition of water to the water tank 2 and prevents external impurities from entering and affecting the water quality; the drain pipe 23 and drain valve 24 at the bottom can promptly drain residual water or wastewater from the water tank 2, facilitating the cleaning of the water tank 2.

[0029] In a preferred embodiment, a support block 51 is fixedly installed at each of the four corners of the bottom of the lower support frame 5, and an air vent 12 is provided at the bottom of the incubator body 1. The support legs 6 at the bottom of the lower support frame 5 can stably support the support frame 5 and the upper structure.

[0030] In a preferred embodiment, a horizontal plate 42 is fixedly installed inside the air box 4. Several drive motors 43 are mounted on the horizontal plate 42. Each drive motor 43 has its output shaft coaxially fixed with a rotating shaft 44, and a fan blade 45 is coaxially fixed on the rotating shaft 44. The drive motors 43 on the horizontal plate 42 inside the air box 4 drive the fan blades 45 to rotate, efficiently delivering external air or hot air from the heating chamber 3 into the incubator, enhancing airflow speed, and allowing the heat emitted by the heat pipe 31 to diffuse more quickly throughout the chamber.

[0031] In a preferred embodiment, the top of the air blower 4 is fixed to the top of the air blower 4 by fixing bolts located at the four corners, and a protective filter 41 is installed inside the mounting frame 40. This filter can filter the air entering the air blower 4, preventing dust, impurities, and microorganisms from entering the incubator.

[0032] As a preferred embodiment, a support leg 6 is fixedly installed at each of the four corners of the bottom of the incubator body 1. The support legs 6 at the four corners of the bottom of the incubator body 1 can stably support the entire incubator on the ground, avoiding direct contact between the incubator body and the ground.

[0033] When using the constant temperature and humidity incubator for Dendrobium tissue culture seedlings of this utility model, with the incubator body 1 as the core, the tissue culture seedlings are first placed on the annular turntable 52 of the internal support frame 5 (the turntable can rotate and the layered design of the support frame 5 improves the space utilization). The temperature and humidity sensors 14 inside the box monitor the environmental parameters in real time. When the temperature is insufficient, the heating box 3 generates heat, and the motor in the blower box 4 drives the fan blades 45 to form an airflow, which introduces the heat into the annular array of heat-conducting pipes 31 (the heat-conducting pipes 31 extend to different heights inside the box), and then diffuses the heat evenly through the exhaust holes 310 of the heat-conducting pipes 31 to stabilize the temperature. When humidity is insufficient, water from water tank 2 is atomized through water pipe 21 to atomizer 22, and water mist is evenly sprayed into the box through atomizing nozzle 26 on inner extension pipe 25 to increase humidity (water tank 2 can be replenished with water through box cover 20 and drained and cleaned through drain valve 24); at the same time, the protective filter screen 41 on the top of the blower box 4 filters the intake air, and the air outlet 12 at the bottom of the box forms an airflow circulation with the blower box 4 to ensure air quality. In addition, the double box door 10 facilitates operation and reduces the loss of temperature and humidity, while the support frame 5 and the support legs 6 at the bottom of the box ensure overall stability. All components work together to achieve precise control of the growth environment of tissue culture seedlings.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
