Description

Technical Field

[0001] This utility model relates to the field of potato cultivation technology, specifically to a temperature-controlled potato virus-free seed potato cultivation box. Background Technology

[0002] Virus-free seed potatoes refer to seed potatoes that have undergone a series of technical measures to remove viruses from their tubers, resulting in seed potatoes that are virus-free or have very little virus infection. They have advantages such as early maturity, high yield, and good quality. During the virus-free seed potato tissue culture process, the potatoes need to be cultivated in an incubator to catalyze rapid sprouting. Usually, fine sand is used to cover the seed potatoes to ensure that they have sufficient moisture for sprouting and growth, while also providing good ventilation to effectively prevent mold. At the same time, it is necessary to regularly observe, record, and analyze the sprouting situation.

[0003] In the prior art, Chinese utility model publication CN210641829U discloses a potato seed tuber virus-free cultivation box, including a box body. Vertical rods are fixed vertically on both sides of the upper end of the box body. Two retaining rings are fixed on the vertical rods respectively. A sleeve is provided between the retaining rings, which is fitted onto the outer wall of the vertical rod and slidably connected to it. A first spring is provided at the lower end of the sleeve. A connecting rod is horizontally fixed to the side end of the sleeve. A rotating shaft is fitted onto the connecting rod and rotatably connected to it. A spherical shell is fixed between the rotating shafts. Two parallel fixing rings are fixed on the upper end of the inner wall of the spherical shell respectively. A perforated plate is provided between the fixing rings. A second spring is fixed around the perforated plate. A cover is hinged to one end of the spherical shell, and a handle is fixed to the other end of the spherical shell.

[0004] In the aforementioned technology, the connection to the outside world is only through multiple ventilation hoods, without any filtration components. Bacteria, fungal spores, and other microorganisms in the outside air can directly enter the shell through the ventilation hoods, resulting in an extremely high contamination rate of virus-free seedlings, especially sensitive materials such as stem tip tissue. At the same time, the device only installs a thermometer and hygrometer on the cover, which can only achieve passive temperature display and cannot be adjusted. It relies entirely on the external ambient temperature and cannot maintain the constant temperature and other key growth conditions required for potato virus removal, which may lead to stunted or deformed seed potato growth, thus having certain limitations. Utility Model Content

[0005] The purpose of this invention is to provide a temperature-controlled potato virus-free seed potato cultivation box to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A temperature-controlled potato virus-free seed potato cultivation box includes a box body. A purification box is fixedly installed on one side of the upper end of the box body. A sealing plate is threadedly connected to one end of the purification box via screws. A primary filter plate, a medium-efficiency filter plate, and a high-efficiency filter plate are sequentially slidably snapped into the middle of the purification box. An air suction pipe is connected and fixed to one end of the purification box. An air suction fan is fixedly installed in the middle of the air suction pipe. An air guide pipe is connected and fixed to the other end of the purification box. A sleeve is connected and fixed to the middle of the air guide pipe. Multiple electric heating tubes are evenly fixedly installed in the middle of the sleeve. An air inlet pipe is connected and fixed to the lower end of the air guide pipe. One end of the air inlet pipe is sequentially connected and fixed to the box body. A diverter plate is fixedly installed in the middle of the middle of one end of the air inlet pipe.

[0007] In some embodiments, partitions are fixedly installed at the top and bottom of the middle of the box, and through holes are opened on the surface of each partition. Multiple containers are evenly inserted into the surface of each partition, and water intake holes are opened at the lower ends of each of the multiple containers.

[0008] In some embodiments, a plurality of water storage boxes are uniformly fixedly installed at the lower end of the partition, and a water guide pipe is fixedly connected to one end of each of the plurality of water storage boxes. The plurality of water guide pipes pass through one end of the box body, and the lower ends of the plurality of containers are located in the middle of the corresponding water storage box.

[0009] In some embodiments, a door is rotatably mounted on the other end of the box via a hinge, an observation window is provided above the middle of the door, a door handle is fixedly mounted on one side of the middle of the door, and a ventilation door is rotatably mounted on the middle of the other side of the box via a hinge.

Through a three-stage filtration purification box and directional airflow design, the air cleanliness entering the box can be raised to a Class 100 sterile standard. Combined with the visual monitoring of the transparent container and the sterile water replenishment method using bottom-drawing, the risk of air pollution is blocked at the source. Simultaneously, the controller achieves automated control of temperature and CO2 concentration through programming, avoiding environmental fluctuations caused by human error. It adapts to the growth needs of potatoes at each stage of virus-free cultivation, significantly improving the qualification rate of virus-free seedlings and effectively solving the pain points of high contamination rates and uneven growth in traditional cultivation methods.

[0013] 2. When this utility model is in use, the through holes on the surface of the partition can help sterile air circulate between the layers, reduce the difference in temperature, humidity and CO2 concentration between the upper and lower layers, ensure that the seed potatoes of different levels have a consistent growth environment, and avoid differences in growth rate caused by uneven environment. At the same time, a ventilation door that can be opened and closed is also set in the box. In the event of a sudden increase in CO2 concentration in the box, the ventilation door of the box can be opened manually to quickly realize the exchange of air between the box and the outside, and help reduce the CO2 concentration.

[0016] 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.

[0017] Example 1: Please refer to Figure 1 - Figure 5This utility model provides a technical solution: a temperature-controlled potato virus-free seed potato cultivation box, including a box body 1. A purification box 2 is fixedly installed on one side of the upper end of the box body 1. A sealing plate 21 is threadedly connected to one end of the purification box 2 by screws. A primary filter plate 22, a medium-efficiency filter plate 23, and a high-efficiency filter plate 24 are sequentially slidably snapped into the middle of the purification box 2. An air suction pipe 25 is fixedly connected to one end of the purification box 2, and an air suction fan 26 is fixedly installed in the middle of the air suction pipe 25. An air guide pipe 27 is fixedly connected to the other end of the purification box 2, and a sleeve 271 is fixedly connected to the middle of the air guide pipe 27. Multiple electric heating tubes 28 are evenly fixedly installed in the middle of the box. The lower end of the air duct 27 is connected to the air inlet duct 29. One end of the air inlet duct 29 is connected to the box body 1 in sequence. A diverter plate 30 is fixedly installed in the middle of one end of the air inlet duct 29. A carbon dioxide sensor 16 is fixedly installed on one side of the upper middle of the box body 1. A temperature sensor 17 is fixedly installed on the other side of the upper middle of the box body 1. A controller 14 is fixedly installed on the upper part of the middle of the other end of the box body 1. The carbon dioxide sensor 16, the temperature sensor 17, the exhaust fan 26 and the electric heating tubes 28 are electrically connected to the controller 14 respectively.

[0018] In this embodiment, a primary filter plate 22, a medium-efficiency filter plate 23, and a high-efficiency filter plate 24 are sequentially arranged inside the purification chamber 2 to intercept large particulate impurities, fine particulate matter, and microorganisms such as bacteria and fungal spores, respectively. This significantly improves the cleanliness of the air entering the chamber 1 and significantly reduces the contamination rate of the virus-free seedlings caused by air pollution. The purification chamber 2 is fixed by a sealing plate 21 and screws. The primary filter plate 22, medium-efficiency filter plate 23, and high-efficiency filter plate 24 adopt a sliding snap-fit ​​design, which allows for quick replacement of filter media and reduces maintenance downtime. The suction fan 26 draws in outside air through the suction pipe 25, and after purification, it is directed into the chamber 1 through the air guide pipe 27 and the air inlet pipe 29. With the help of the distribution plate 30, the sterile air is distributed to various areas inside the chamber to ensure that the culture is in a sterile air environment. The temperature sensor 17 can collect the temperature inside the chamber in real time and feed it back to the chamber. When the temperature is below the suitable range for virus-free cultivation, the controller 14 automatically activates the electric heating tube 28 to heat the purified air through the sleeve 271, and then sends it into the chamber 1 through the air duct to achieve temperature rise. Once the temperature reaches the target, it automatically shuts off to avoid abnormal seedling growth caused by large temperature fluctuations inside the chamber 1. The carbon dioxide sensor 16 can monitor the CO2 content in the chamber in real time. If the concentration is too high, the controller 14 can increase the intake of fresh air by adjusting the speed of the suction fan 26 to dilute the CO2 concentration. If the concentration is too low, it will reduce the fan speed to reduce ventilation and ensure photosynthetic efficiency. The controller 14 centrally connects and controls various sensors, suction fan 26, and electric heating tube 28 to achieve automated monitoring and adjustment of environmental parameters. It eliminates the need for frequent manual inspections and adjustments, reduces operational errors, and is suitable for standardized management in large-scale cultivation scenarios.

[0019] Example 2: As Figure 1- Figure 4 As shown, partitions 18 are fixedly installed on the upper and lower parts of the middle of the box 1. Through holes 19 are opened on the surface of each partition 18. Multiple containers 20 are evenly inserted into the surface of each partition 18. Water intake holes 201 are opened at the lower end of each container 20. Multiple water storage boxes 202 are evenly fixedly installed at the lower end of each partition 18. A water guide pipe 203 is fixedly connected to one end of each water storage box 202. The multiple water guide pipes 203 pass through one end of the box 1 respectively. The lower ends of each container 20 are located in the middle of the corresponding water storage box 202. A door 11 is installed at the other end of the box 1 by hinge. An observation window 12 is provided above the middle of the door 11. A door handle 13 is fixedly installed on one side of the middle of the door 11. A ventilation door 15 is installed in the middle of the other side of the box 1 by hinge.

[0020] In this embodiment, the partitions 18 installed at the top and bottom of the middle of the box 1 can form independent cultivation spaces, allowing multiple sets of containers 20 to be placed simultaneously for seed potato virus-free cultivation, greatly improving space utilization. The containers 20 are used to hold seed potatoes and nutrient soil. The through holes 19 on the surface of the partitions 18 assist airflow within the box, accelerating the circulation of purified air, reducing temperature and CO2 concentration differences between upper and lower layers, and ensuring a consistent growth environment for cultures in each layer. A water intake hole 201 is provided at the bottom of the container 20 and placed inside a water storage box 202. Through capillary action, the cultures can slowly absorb water from the water storage box 202 without the need for manual watering, reducing the probability of contamination at the source. The observation window 12 allows for... This allows operators to monitor the growth status of seed potatoes, such as stem tip tissue and virus-free seedlings, inside container 20 in real time without opening the door. This includes observing leaf color and callus formation, preventing fluctuations in temperature and humidity and the intrusion of external contaminants caused by opening the door. The ventilation door 15 on the other side of the container 1 allows for rapid air exchange when the CO2 concentration inside the container rises sharply. Both container 20 and water storage box 202 are made of transparent material, such as high-transmittance PC or glass, allowing operators to clearly see the condition of the internal culture medium and promptly observe the remaining water in the water storage box 202. Sterile water can be added in a timely manner through the water pipe 203 to prevent the culture medium from drying out due to lack of water.

[0021] Working principle: like Figure 1 - Figure 5As shown, the upper and lower partitions 18 in the middle of the box 1 divide the interior into multiple independent cultivation spaces. Each layer can hold multiple sets of containers 20, greatly improving space utilization. At the same time, the through holes 19 on the surface of the partitions 18 can facilitate the circulation of sterile air between layers, reducing differences in temperature, humidity, and CO2 concentration between upper and lower layers, ensuring a consistent growth environment for seed potatoes in different layers, and avoiding differences in growth rate caused by uneven environment. Seed potatoes and culture medium are placed in the containers 20, and the water intake holes 201 at the bottom of the containers extend into the corresponding water storage boxes 202 below. Using the capillary absorption principle, the culture medium can slowly draw water from the water storage box 202 without the need for manual water replenishment. Operators can visually observe the remaining water level through the transparent water storage box 202. When the water level is insufficient, sterile water can be added to the water storage box 202 through the water pipe 203 to prevent the culture medium from drying out and affecting the growth of seed potatoes. Both the container 20 and the water storage box 202 are made of high light transmittance materials such as PC or glass, allowing operators to directly observe the growth details of the seed potatoes inside the container 20 through the observation window 12 on the box door 11.

[0022] The controller 14 activates the suction fan 26, which draws in outside air through the suction pipe 25. The air first enters the purification chamber 2. Inside the purification chamber 2, the air passes through a primary filter 22 to intercept large particles such as dust and hair, a medium-efficiency filter 23 to filter pollen and fine dust particles, and a high-efficiency filter 24 to intercept microorganisms such as bacteria and fungal spores. After three stages of filtration, the air cleanliness reaches the Class 100 sterile standard required for detoxification cultivation, blocking the risk of airborne pollution at the source. The purified sterile air enters the sleeve 271 through the air duct 27. If the temperature sensor 17 detects that the temperature inside the chamber is lower than the suitable range, the controller 14 will simultaneously activate the electric heating element 28 to heat the sterile air. The heated sterile air is then sent into the chamber 1 through the air inlet pipe 29, and the airflow is dispersed by the diverter 30 inside the air inlet pipe 29 to avoid local airflow concentration. Ultimately, the sterile air evenly covers all areas of the chamber 1, ensuring that the seed potatoes in all cultivation containers 20 are in a sterile environment. During the process, temperature sensor 17 continuously collects temperature data inside chamber 1 and feeds the signal back to controller 14. When the temperature is below or above the set threshold, the heating element 28 can be automatically turned on and off to keep the temperature inside chamber 1 within a suitable range. Carbon dioxide sensor 16 can monitor the CO2 content inside the chamber in real time and is linked with controller 14. If the CO2 concentration is too high, controller 14 increases the speed of suction fan 26 to increase the intake of fresh sterile air and dilute the CO2 concentration inside the chamber. If a sudden increase in CO2 concentration occurs, the operator can manually open the ventilation door 15 on the other side of chamber 1 to quickly exchange air between the inside and outside of the chamber and help reduce the CO2 concentration.

[0023] The sealing plate 21 of the purification chamber 2 is fixed with screws. The primary filter plate 22, medium-efficiency filter plate 23, and high-efficiency filter plate 24 adopt a sliding snap-fit ​​design. When the filter media reaches the end of its service life, the operator can remove the sealing plate 21, directly pull out the old filter media and insert the new filter media, without disassembling the entire machine. Maintenance downtime is reduced to within minutes, reducing the management cost of large-scale cultivation. All sensors and actuators are centrally controlled by the controller 14. Operators do not need to frequently inspect and adjust parameters. They only need to set the target value through the controller 14 panel to achieve automated management of environmental parameters, reduce human error, and adapt to the standardized needs of small and medium-sized large-scale cultivation. The function of centrally controlling all sensors and actuators through the controller 14 can be fully implemented through programming, which is existing technology and will not be elaborated further.
