Description

Technical Field

[0001] This utility model relates to the field of biological incubator technology, specifically to a biological incubator that is easy to control temperature. Background Technology

[0002] As a constant temperature device with bidirectional temperature regulation functions of cooling and heating, the biological incubator is an indispensable basic device for scientific research and teaching in fields such as botany, microbiology, genetics, virology research and environmental monitoring. It is widely used in key scenarios such as constant temperature culture, biochemical experiments and environmental simulation.

[0003] Currently, most common biological incubators use a combination of heaters and coolers with fans to achieve temperature control. However, this method has the following limitations: First, both hot and cold air need to be purified by filters during transportation. After long-term operation, impurities easily accumulate on the filters, affecting temperature control efficiency and requiring frequent disassembly and cleaning. Second, hot and cold air rely heavily on natural mixing within the incubator, which can easily create temperature gradients, resulting in poor temperature uniformity within the incubator, affecting the consistency of culture conditions and the reliability of experimental results. Based on this, this solution provides a biological incubator with easy temperature control to address the aforementioned problems. Utility Model Content

[0028] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0029] Reference Figure 1-2 As shown, a biological incubator that is easy to control temperature includes an incubator 1. A partition 2 is fixedly connected to the inner wall of the incubator 1. A placement seat 3 for placing petri dishes is fixedly installed on the partition 2. A temperature monitor 5 is fixedly installed on the inner wall of the incubator 1 on the outer side of the placement seat 3. A temperature control device 4 is fixedly installed on the lower side of the partition 2. The temperature control device 4 includes a filter 41, a drive 42, a mixing 43 and an air outlet 44.

[0030] Furthermore, in the filter section 41 of this utility model, heating and cooling are carried out independently through the first cavity and then the second cavity. The hot air and cold air are proportionally regulated by the three-way confluence regulating valve 427, and finally the temperature is forced to be uniform by the mixing blades 433. With the real-time feedback of the temperature monitor 5, the temperature of the culture area is precisely controlled, which solves the problems of large temperature fluctuations and local temperature differences in traditional equipment and meets the requirements of fine temperature control in biological culture.

[0031] Reference Figure 3 As shown, specifically, in this embodiment, the filter unit 41 includes a filter box 411 fixedly installed on the bottom plate of the incubator 1. The filter box 411 is provided with a first cavity and a second cavity, and both the first cavity and the second cavity are provided with filter screens 416. The filter box 411 is provided with a cleaning component for cleaning the filter screens 416.

[0032] Reference Figure 3 As shown, specifically in this embodiment, an air heater 412 and an air cooler 413 are fixedly installed in the first cavity and the second cavity, respectively, and mounting bracket 1 414 and mounting bracket 2 415 are slidably installed. Two sets of filter screens 416 are provided and are fixedly installed inside the mounting bracket 1 414 and mounting bracket 2 415, respectively.

[0033] Furthermore: external air enters the two chambers through the air inlet pipes 4114 of the first and second chambers respectively; the air is heated by the air heater 412 in the first chamber and cooled by the air cooler 413 in the second chamber, forming hot air and cold air; impurities are intercepted by the filter screens 416 in the mounting bracket 1 414 and mounting bracket 2 415 to ensure the cleanliness of the hot air and cold air, and finally introduced into the incubator 1 by the drive unit 42.

[0034] Reference Figure 3 As shown, specifically in this embodiment, the cleaning component includes a motor 417 fixedly installed on the incubator 1. The output shaft of the motor 417 is fixedly connected to a crank 418. A drive rod 419 is fixedly connected to the crank 418. A movable frame 4110 is slidably connected to the drive rod 419. Connecting rods 4111 are fixedly connected to both sides of the movable frame 4110. The connecting rods 4111 on both sides pass through the first cavity and the second cavity respectively and are fixedly installed with cleaning brushes 4112.

[0035] Furthermore: The starter motor 417, with its output shaft driving the crank 418 to rotate, drives the drive rod 419 to move, causing the slidingly connected movable frame 4110 to reciprocate. The movable frame 4110, through connecting rods 4111 on both sides, drives the cleaning brush 4112 to move synchronously. The cleaning brush 4112 slides along the surface of the filter screen 416 in the first and second cavities respectively, scraping off impurities attached to the filter screen 416. This effectively replaces manual disassembly and cleaning, avoiding interruption of the cultivation process. During cleaning, the sealing plate 4113 remains closed to ensure chamber sealing and prevent external impurities from entering or internal hot and cold air from leaking.

[0036] Reference Figure 4 As shown, specifically in this embodiment, the top of both mounting bracket 1 414 and mounting bracket 2 415 are provided with sealing plates 4113 that are rotatably mounted on the filter box 411. The right ends of the first cavity and the second cavity are both fixedly installed with air inlet pipes 4114, and the left ends of the first cavity and the second cavity are both connected to the drive unit 42.

[0037] Furthermore, the dual-cavity design with a first cavity and a second cavity allows for independent processing of hot and cold air, avoiding heat exchange losses. The filter screen 416 intercepts dust and other impurities, ensuring the cleanliness of the air entering the incubator 1 and preventing contamination of the culture samples. Meanwhile, the mounting brackets 414 and 415 are slidable and, together with the top rotating and opening sealing plate 4113, facilitate the later disassembly and replacement of the filter screen 416, improving maintenance flexibility.

[0038] Reference Figure 5As shown, specifically in this embodiment, the drive unit 42 includes a first fan 421 and a second fan 422 fixedly installed at the bottom of the incubator 1, and a three-way confluence regulating valve 427 fixedly installed at the outer end of the incubator 1. The input ends of the first fan 421 and the second fan 422 are respectively fixedly installed with a connecting pipe 423 and a connecting pipe 424, which are respectively connected to the first cavity and the second cavity. The output ends of the first fan 421 and the second fan 422 are respectively fixedly installed with a vent pipe 425 and a vent pipe 426, which are respectively connected to the two inlets of the three-way confluence regulating valve 427. The outlet of the three-way confluence regulating valve 427 is fixedly installed with a vent pipe 428 connected to the mixing unit 43.

[0039] Furthermore: the first fan 421 draws clean hot air from the first cavity through the connecting pipe 423 and sends it into the three-way confluence regulating valve 427 through the air guide pipe 425; the second fan 422 draws clean cold air from the second cavity through the connecting pipe 424 and sends it into the three-way confluence regulating valve 427 through the air guide pipe 426; according to the temperature of the culture area fed back by the temperature monitor 5, the three-way confluence regulating valve 427 adjusts the input ratio of hot air and cold air, and the mixed airflow is sent into the mixing section 43 through the ventilation pipe 428 for mixing treatment.

[0040] Reference Figure 6 As shown, specifically, in this embodiment, the mixing unit 43 includes a mixing box 431 fixedly installed on the outer end of the incubator 1, and a second motor 432 fixedly installed on the mixing box 431. The output shaft of the second motor 432 is fixedly connected to a mixing blade 433. The lower end of the mixing box 431 is connected to a vent pipe 428, and the upper end of the mixing box 431 is fixedly installed with an air outlet pipe 434 connected to an air outlet 44.

[0041] Furthermore: the airflow after adjustment enters the mixing chamber 431, the second motor 432 is started, and its output shaft drives the mixing blades 433 to rotate at high speed, forcibly stirring the airflow; the forced stirring by the mixing blades 433 replaces the traditional natural diffusion, effectively solving the problem of local temperature difference caused by uneven airflow mixing; finally, the fully mixed constant temperature airflow is sent to the air outlet 44 through the air outlet pipe 434, and finally enters the incubator 1 to provide a stable temperature environment for the petri dish.

[0042] Reference Figure 2 As shown, specifically in this embodiment, the air outlet 44 is fixedly installed at the top of the incubator 1.

[0043] The working principle of this utility model is as follows: When in use, external air enters the two chambers through the air inlet pipes 4114 of the first chamber and the second chamber respectively; the air is heated by the air heater 412 in the first chamber and cooled by the air cooler 413 in the second chamber, forming hot air and cold air.

[0044] Subsequently, the first fan 421 draws clean hot air from the first cavity through the connecting pipe 423 and sends it into the three-way confluence regulating valve 427 through the air guide pipe 425; the second fan 422 draws clean cold air from the second cavity through the connecting pipe 424 and sends it into the three-way confluence regulating valve 427 through the air guide pipe 426; according to the temperature of the culture area fed back by the temperature monitor 5, the three-way confluence regulating valve 427 adjusts the input ratio of hot air and cold air, and the mixed airflow is sent into the mixing section 43 through the ventilation pipe 428 for mixing treatment;

[0045] When the adjusted airflow enters the mixing chamber 431, the second motor 432 is started, and its output shaft drives the mixing blades 433 to rotate at high speed, forcibly stirring the airflow. The forced stirring by the mixing blades 433 replaces the traditional natural diffusion, effectively solving the problem of local temperature difference caused by uneven airflow mixing. Finally, the fully mixed constant temperature airflow is sent to the air outlet 44 through the air outlet pipe 434 and finally enters the incubator 1 to provide a stable temperature environment for the petri dish.

[0046] Simultaneously, the cleaning assembly, via the starter motor 417, rotates the crank 418 through its output shaft. The crank 418 drives the drive rod 419, causing the slidingly connected movable frame 4110 to reciprocate. The movable frame 4110, through connecting rods 4111 on both sides, drives the cleaning brush 4112 to move synchronously. The cleaning brush 4112 slides along the surface of the filter screen 416 in the first and second cavities, scraping away impurities attached to the filter screen 416. This effectively replaces manual disassembly and cleaning, avoiding interruption of the cultivation process. During the cleaning process, the sealing plate 4113 remains closed to ensure the chamber's airtightness and prevent external impurities from entering or internal hot and cold air from leaking.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
