Technical Field
[0001] This utility model relates to the field of biological culture technology, specifically a biological incubator with a quickly replaceable culture rack. Background Technology
[0002] In fields such as biological experiments, pharmaceutical research and development, and microbial culture, bioincubators are core equipment for ensuring stable sample growth. Their core requirements focus on three dimensions: controllability of the culture environment, ease of operation, and equipment compatibility. However, with the diversification of experimental sample types and the increasing demands for efficiency in experimental procedures, existing bioincubators have gradually revealed numerous technical shortcomings, making it difficult to meet practical application needs. First, existing incubators mostly use fixed installation structures for their culture racks. The culture trays are locked to the incubator body by bolts, welding, or complex snap-fit connections. This means that when replacing the culture rack, multiple parts need to be disassembled with tools, which is cumbersome and time-consuming. The existing air purification and replacement systems of incubators have problems such as poor sealing performance and poor controllability of replacement efficiency. In some devices, the purification module is connected to the incubator body with a gap fit, which can easily lead to clean air leakage and make it impossible to maintain a stable cleanliness inside the incubator. Utility Model Content
[0003] The purpose of this invention is to provide a biological incubator with a quickly replaceable culture rack to solve the problems mentioned in the prior art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: A biological incubator with a quickly replaceable culture rack includes a base, an incubator body, a culture tray, and guide rails. The incubator body is positioned directly above the base. A control module is installed inside the incubator body, and the control module is electrically connected to a servo air pump. A filtration mechanism is installed inside the incubator body. This filtration mechanism draws in air through its built-in filter and introduces it into a purification chamber. After purification in the purification chamber, the servo air pumps the filtered air into the incubator body, achieving air replacement and renewal within the incubator body. A separation mechanism is installed inside the incubator body. This separation mechanism is connected to both sides of the culture tray via symmetrically arranged guide rails. Simultaneously, a side cover is fitted to one side of the culture tray. The side cover is magnetically connected to the incubator body using a magnetic strip, ensuring the airtightness of the incubator body and allowing the culture tray to slide smoothly along the guide rails by external force, achieving rapid separation from the incubator body.
[0005] As a preferred technical solution, the filtration mechanism includes a purification chamber, a threaded pipe, a servo air pump, a filter element, fasteners, and an air inlet cover. The purification chamber is snapped into the middle of the base. The bottom end of the threaded pipe is located directly above the purification chamber. The threaded pipe is connected to the bottom end of the culture chamber. The servo air pump is located inside the culture chamber. The filter element is located at the bottom end of the purification chamber. The bottom end of the purification chamber is connected to the air inlet cover. Fasteners are distributed in a ring on the outer side of the air inlet cover. The tail end of the fasteners is connected to the bottom end of the purification chamber.
[0006] As a preferred technical solution, the purification chamber achieves a through-sealing with the bottom of the culture chamber through a threaded pipe fitting at its top.
[0007] As a preferred technical solution, the servo air pump is connected to the top end of the threaded pipe fitting, and the other end of the threaded pipe fitting is connected to the interior of the purification chamber.
[0008] As a preferred technical solution, the separation mechanism includes an aluminum alloy mesh plate, a side cover plate, a slider, a culture tray, a guide rail, and a magnetic strip. The aluminum alloy mesh plate is connected through the culture tray. The side cover plate is connected to one side of the culture tray. The slider is connected to both sides of the culture tray. The outer side of the slider is slidably engaged with the guide rail. The guide rail is fixed to the inner end of the culture chamber. The magnetic strip is glued to the top of the side cover plate.
[0009] As a preferred technical solution, the side cover plate is magnetically connected to the inner end of the incubator body through a magnetic strip arranged at its top.
[0010] As a preferred technical solution, the sliders are respectively disposed on both sides of the culture tray, and the culture tray slides with the guide rails on both sides via the sliders.
[0011] As a preferred technical solution, the control module has a built-in programmable control chip, power management unit and signal transmission module, and is connected to the servo air pump through wires to form a stable electrical connection.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model adopts a combination design of sliding cooperation of slider and guide rail and magnetic sealing of magnetic strip through separation mechanism. The disassembly and assembly of culture tray does not require tools such as wrenches and screws. It can be completed by pulling and pushing the side cover plate with external force. By disassembling the relevant fixing parts, the installation spacing of multiple sets of guide rails can be adjusted as needed to achieve compatibility with culture dishes and culture bottles of different sizes. It is convenient for batch placement and replacement of samples, and also facilitates thorough cleaning of the inside of the culture box.
[0013] 2. This utility model achieves a freely adjustable structure by using bolts to fix the slide rails with interlayer spacing, which can be adapted to culture dishes and culture bottles of different sizes, greatly improving the convenience of sample replacement and the cleaning efficiency of the inside of the culture box. Compared with the bolt locking or buckle fixing structure of traditional culture boxes, it greatly shortens the operation time of culture rack replacement, and can be completed by a single person, reducing the workload of experimental personnel.
[0014] 3. The purification chamber is connected to the bottom of the incubation chamber through a threaded pipe fitting at the top, achieving a through-sealed connection. The threaded connection structure and sealing design completely solve the air leakage problem caused by the gap between the purification module and the chamber in existing equipment, ensuring that all clean air is injected into the incubation chamber. The air inlet cover at the bottom of the purification chamber is fixed by a ring of fasteners. The air inlet cover can be opened by removing the fasteners, and the filter element can be quickly replaced without disassembling the main body of the purification chamber or related air circuit components.

Detailed Implementation
[0017] 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.
[0018] Example: Figures 1 to 6As shown, this utility model provides the following technical solution: a biological incubator with a quickly replaceable culture rack, including a base 1, an incubator body 2, a culture tray 8, and a guide rail 10. The incubator body 2 is positioned directly above the base 1. A control module 6 is installed inside the incubator body 2, and the control module 6 is electrically connected to a servo air pump 13. A filter mechanism 5 is installed inside the incubator body 2. The filter mechanism 5 draws in air through its built-in filter element 14 and introduces it into a purification chamber 11. After being purified by the purification chamber 11, the filtered air is pumped into the incubator body 2 by the servo air pump 13, achieving purification within the incubator body 2. The air exchange mechanism 9 is installed inside the culture chamber 2 to replace and renew the air. The separation mechanism 9 is connected to both sides of the culture tray 8 through symmetrically arranged guide rails 10. At the same time, a side cover plate 4 is installed on one side of the culture tray 8. The side cover plate 4 is magnetically connected to the culture chamber 2 by a magnetic strip 17. This can ensure the airtightness of the culture chamber 2 and allow the culture tray 8 to slide smoothly out along the guide rail 10 by external force, so as to achieve rapid separation from the culture chamber 2. The control module 6 has a built-in programmable control chip, power management unit and signal transmission module, and is connected to the servo air pump 13 through wires to form a stable electrical connection.
[0019] Specifically: the control module 6 outputs an electrical signal to the servo air pump 13 to drive the servo air pump 13 to operate. The servo air pump 13 pumps clean air from the purification chamber 11 into the culture chamber 2 through the threaded pipe 12 connected to the top of the purification chamber 11. After the clean air enters the culture chamber 2, it squeezes the original air in the chamber to complete the replacement, ensuring that the oxygen concentration and air cleanliness in the chamber meet the requirements of biological culture.
[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the filtration mechanism 5 includes a purification chamber 11, a threaded pipe 12, a servo air pump 13, a filter element 14, fasteners 15, and an air inlet cover 16. The purification chamber 11 is snapped into the middle of the base 1. The bottom end of the threaded pipe 12 is located directly above the purification chamber 11. The threaded pipe 12 is connected to the bottom end of the culture chamber 2. The servo air pump 13 is located inside the culture chamber 2. The filter element 14 is located at the bottom end of the purification chamber 11. The bottom end of the purification chamber 11 is connected to the air inlet cover 16. Fasteners 15 are distributed in a ring on the outer side of the air inlet cover 16. The tail end of the fasteners 15 is connected to the bottom end of the purification chamber 11. The purification chamber 11 achieves a through-sealing with the bottom end of the culture chamber 2 through the threaded pipe 12 arranged at its top. The servo air pump 13 is connected to the top end of the threaded pipe 12. The other end of the threaded pipe 12 is connected to the interior of the purification chamber 11.
[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the separation mechanism 9 includes an aluminum alloy mesh plate 3, a side cover plate 4, a slider 7, a culture tray 8, a guide rail 10, and a magnetic strip 17. The aluminum alloy mesh plate 3 is connected through the culture tray 8. The side cover plate 4 is connected to one side of the culture tray 8. The slider 7 is connected to both sides of the culture tray 8. The outer side of the slider 7 is slidably engaged with the guide rail 10. The guide rail 10 is fixed to the inner end of the culture chamber 2. The magnetic strip 17 is glued to the top of the side cover plate 4. The side cover plate 4 is magnetically connected to the inner end of the culture chamber 2 through the magnetic strip 17 arranged at its top. The slider 7 is disposed on both sides of the culture tray 8. The culture tray 8 is slidably engaged with the guide rail 10 on both sides through the slider 7.
[0022] Among them, the aluminum alloy mesh plate 3 and the culture tray 8 are connected through, which not only provides support for the culture, but also does not affect the air circulation inside the chamber; the control module 6, as the core control unit, realizes the start and stop, speed adjustment and fault protection of the servo air pump 13, so that the two major functions of air purification and replacement and culture tray replacement are independent of each other and work together to ensure the stable and efficient operation of the entire incubator.
[0023] The working principle of this utility model is as follows: the outside air first undergoes primary filtration through the filter element 14 at the bottom of the purification chamber 11, which traps particulate matter, bacteria and other pollutants in the air. The preliminarily purified air enters the purification chamber 11 for temporary storage. The control module 6 outputs an electrical signal to the servo air pump 13 to drive the servo air pump 13 to operate. Through the threaded pipe 12 connected to the top of the purification chamber 11, the clean air in the purification chamber 11 is pumped into the incubation chamber 2, which squeezes the original air in the chamber to complete the replacement, ensuring the oxygen concentration and air cleanliness in the chamber. The control module 6 can adjust the speed of the servo air pump 13 according to the preset program or external command to realize multi-level control of air delivery rate and adapt to the needs of different cultivation scenarios; at the same time, it monitors the operating current, temperature and other parameters of the servo air pump 13 in real time. If an abnormal working condition such as overload or stall occurs, it will immediately cut off the power supply circuit and trigger an alarm to ensure the safe operation of the system. The guide rail 10 in the separation mechanism 9 is fixed to the inner end of the culture chamber 2. The sliders 7 on both sides of the culture tray 8 slide with the guide rail 10 to provide stable guidance for the tray to be pulled out. The side cover 4 on one side of the culture tray 8 is magnetically attached to the inner end of the culture chamber 2 through the magnetic strip 17 at the top, so as to achieve the sealing of the culture chamber 2.
[0024] When it is necessary to replace the culture tray 8, apply external force to pull the side cover plate 4, the magnetic connection is unlocked, and drag the side cover plate 4 to drive the culture tray 8 to slide out of the culture box 2 along the guide rail 10; after the replacement is completed, push the culture tray 8 in along the guide rail 10, and the magnetic strip 17 automatically magnetically attaches to the culture box 2 to complete the tray reset and sealing fixation.
[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
