Description

Technical Field

[0001] This invention relates to the field of incubator technology, and more specifically, to an electrothermal constant temperature incubator. Background Technology

[0002] Electric thermostatic incubators are fundamental experimental equipment in fields such as medical and health care, biomedicine, agricultural research, and food testing. Their core function is to provide a stable and controllable constant temperature environment. They mainly consist of a chamber, heating elements, temperature sensors, a control system, and an air circulation device. The heating elements convert electrical energy into heat energy, and the temperature sensors monitor the internal temperature in real time. The control system automatically adjusts the start / stop or power of the heating elements to achieve precise temperature control. The chamber typically employs an insulated and sealed structure to reduce heat loss, and a circulating fan ensures temperature uniformity. With technological advancements, various types of incubators have been developed, including electric heating film type and water jacket type, integrating intelligent control and data recording functions to meet the experimental needs of various scenarios such as microbial culture, cell culture, seed germination, and drug stability testing.

[0003] In existing technologies, relying solely on simple temperature controllers for single-point, delayed control leads to significant temperature fluctuations within the chamber around the set value. This results in inconsistent growth states for cultured samples placed in different locations, severely impacting experimental repeatability and data accuracy. Furthermore, using only simple fixed openings or manually adjustable vents fails to allow for flexible adjustments based on actual needs. In existing technologies, when the equipment is subjected to external impact, the impact force is transmitted directly to the interior without any buffering, potentially causing culture vessels to tip over or break, resulting in irreparable sample loss. Moreover, the fixed layer height in existing technologies cannot accommodate culture vessels of varying heights, severely limiting the equipment's versatility and leading to low space utilization and a significant lack of flexibility. Summary of the Invention

[0004] To overcome the above-mentioned defects, the present invention provides an electric thermostatic incubator, which solves the problems of existing technologies that rely solely on simple temperature controllers for single-point, delayed control, resulting in large fluctuations in the internal temperature around the set value; the use of simple fixed openings or manually adjustable ventilation vents, which cannot be flexibly adjusted according to actual needs; the direct transmission of impact force to the interior without any buffer when the equipment is subjected to external impact, which may cause the culture vessels to tip over; and the fixed layer height, which cannot accommodate culture vessels of different heights, seriously limiting the versatility of the equipment.

[0005] According to one aspect, at least one embodiment of the present invention provides an electrically heated constant-temperature incubator, comprising: An incubator, wherein a sealed door is hinged to the front side of the incubator, a controller is fixedly connected to the top of the front side of the sealed door, an observation window is fixedly connected to the front side of the sealed door, and support legs are fixedly connected to the four corners of the bottom of the incubator. A temperature control and intelligent ventilation adjustment component is installed on both the inner and outer sides of the incubator. The temperature control and intelligent ventilation adjustment component is used to intelligently regulate the temperature inside the incubator and adjust the ventilation volume inside the incubator. The buffer and shock absorption assembly consists of four components, each disposed at the bottom of one of the four support legs. A shelf spacing adjustment component is installed inside the incubator and is used to adjust the distance between two adjacent shelf units.

[0006] For example, in an electric thermostatic incubator provided by at least one embodiment of the present invention, the temperature control and intelligent ventilation adjustment component includes two cooling fans. The two cooling fans are fixedly connected to the top of the incubator and are arranged symmetrically from left to right. A plurality of heating wires are fixedly connected to the rear inner wall of the incubator. A plurality of temperature sensors distributed at equal distances from top to bottom are fixedly connected to the inner walls of both the left and right sides of the incubator.

[0007] For example, in an electric thermostatic incubator provided by at least one embodiment of the present invention, a ventilation opening is provided below the right side wall of the incubator. A louvered frame is fixedly connected to the inner wall of the ventilation opening. A plurality of rotating shafts distributed at equal vertical distances are rotatably connected to the inner wall of the louvered frame. Louvers are fixedly connected to the outer walls of the plurality of rotating shafts. The rear ends of the plurality of rotating shafts penetrate to the rear side wall of the louvered frame and are fixedly connected to a rotating plate. A pull rod is rotatably connected to the end of the plurality of rotating plates away from the rotating shafts. A fixed frame is fixedly connected to the rear side wall of the louvered frame. A motor is fixedly connected to the rear side of the fixed frame. The output shaft of the motor penetrates into the interior of the fixed frame and is fixedly connected to one of the rotating shafts.

[0008] For example, in an electric thermostatic incubator provided in at least one embodiment of the present invention, the controller is electrically connected to a cooling fan, a heating wire, a temperature sensor, and a motor.

[0009] For example, in an electric thermostatic incubator provided by at least one embodiment of the present invention, the buffer and shock absorption assembly includes a hollow frame and a lifting plate. The lifting plate is fixedly connected to the bottom of the support leg. Slide rods are fixedly connected to the top left and right sides of the lifting plate. Limit blocks are fixedly connected to the top of the two slide rods. Two symmetrical sliding groove holes are opened on the top of the hollow frame. The inner walls of the two sliding groove holes are slidably connected to the outer walls of the slide rods respectively.

[0010] For example, in an electric thermostatic incubator provided by at least one embodiment of the present invention, dampers are fixedly connected to the four bottom corners of the lifting plate, the bottom of the four dampers are fixedly connected to the inner bottom wall of the hollow frame, and a buffer bottom plate is fixedly connected to the bottom of the hollow frame.

[0011] For example, in an electric thermostatic incubator provided by at least one embodiment of the present invention, the shelf spacing adjustment assembly includes an equidistant adjustment mechanism. The number of the equidistant adjustment mechanisms is two and they are arranged symmetrically on the left and right sides. Several shelf units are arranged at equal vertical distances on the opposite surfaces of the two equidistant adjustment mechanisms.

[0012] For example, in an electrothermal constant temperature incubator provided by at least one embodiment of the present invention, the equidistant adjustment mechanism includes a fixed frame, which is fixedly connected to the inside of the incubator. Rotating rods are rotatably connected to the upper and lower inner walls of the fixed frame. A second motor is fixedly connected to the top of the fixed frame. The output shaft of the second motor passes through the inside of the fixed frame and is fixedly connected to the rotating rods. Four rectangularly distributed sliding columns are fixedly connected to the upper and lower inner walls of the fixed frame. Open-type sliders, adapted to the number of shelf plates, are slidably connected to the outer walls of the four sliding columns. A sliding groove is provided on the side of the open-type slider near the shelf plate, allowing it to slidably connect to the shelf plate. A spiral groove, adapted to the number of shelf plates and symmetrically arranged vertically, is provided on the outer wall of the rotating rod. Limiting sliders, slidably connected to the inner walls of the spiral grooves, are fixedly connected to the side of each of the open-type sliders near the rotating rod. The controller is electrically connected to the second motor.

[0013] The beneficial effects of the embodiments of the present invention are as follows: In this invention, by employing a temperature control and intelligent ventilation adjustment component and utilizing multi-point distributed temperature sensors, the system can comprehensively and in real-time sense the temperature at different locations within the incubator. This avoids blind spots or errors that may exist in single-point temperature measurement. Based on this real-time data, the controller can precisely direct the heating element and cooling fan to work together, quickly compensating for or suppressing minute temperature fluctuations. This keeps the temperature fluctuation range of the entire working chamber within a very small range, providing a crucial constant environment for temperature-sensitive culture samples. Simultaneously, by precisely controlling the opening and closing angle of the louvers via a motor, the ventilation volume can be finely controlled, providing active and controllable ventilation. Furthermore, the included buffer and shock absorption component effectively reduces the impact of airflow during incubator operation. Vibrations from the external environment or the internal environment are effectively absorbed and isolated by the buffer and shock absorption components, providing an extremely stable static or quasi-static environment for vibration-sensitive cultures such as cells, microorganisms, and plant seedlings. This avoids problems such as poor cell adhesion, abnormal colony morphology, and physical damage caused by vibration, fundamentally ensuring the accuracy and reproducibility of experimental results. Through the adjustable shelf spacing components, users can freely and precisely adjust the vertical distance between each shelf according to the actual height of the culture vessel (e.g., from short culture dishes to tall conical flasks), making the most of the internal space of the incubator and avoiding space waste caused by fixed shelf heights, greatly expanding the application range of the equipment.

[0023] like Figures 1-2 As shown, an electrothermal constant temperature incubator according to an embodiment of the present invention is illustrated, comprising: Incubator 1, with a sealing door 10 hinged to the front side of incubator 1, a controller 11 fixedly connected to the top of the front side of sealing door 10, an observation window 12 fixedly connected to the front side of sealing door 10, and support legs 13 fixedly connected to the four corners of the bottom of incubator 1. Temperature control and intelligent ventilation adjustment component 2 is installed on the inner and outer sides of the incubator 1. The temperature control and intelligent ventilation adjustment component 2 is used to intelligently control the temperature inside the incubator 1 and adjust the ventilation volume inside the incubator 1. The number of shock absorbers 3 is four and they are respectively set at the bottom of the four legs 13; The shelf spacing adjustment component 4 is installed inside the incubator 1 and is used to adjust the distance between two adjacent shelves.

[0024] In some examples, the main body of the incubator 1 is made of stainless steel plate, and the internal space is used to place the culture. The front side of the incubator 1 is hinged with a sealing door 10. The sealing door 10 has a sealing strip on the edge to ensure airtightness. The top of the front side of the sealing door 10 is fixedly connected to a controller 11 by bolts. The controller 11 is a programmable logic controller (PLC), model Siemens S7-1200, used to centrally control various electronic components. An observation window 12 is embedded in the middle of the front side of the sealing door 10. The observation window 12 is made of double-layered tempered glass, which makes it easy for users to observe the internal status of the incubator. The bottom four corners of the incubator 1 are welded with support legs 13, which are made of angle steel and used to support the incubator 1.

[0025] like Figures 2-3As shown, it illustrates a temperature control and intelligent ventilation adjustment component 2 in another embodiment of the present invention. The temperature control and intelligent ventilation adjustment component 2 includes two cooling fans 20, which are fixedly connected to the top of the incubator 1 and arranged symmetrically from left to right. A plurality of heating wires 21 are fixedly connected to the rear inner wall of the incubator 1, and a plurality of temperature sensors 22 distributed at equal distances from top to bottom are fixedly connected to the inner walls of both the left and right sides of the incubator 1.

[0026] A ventilation opening is provided on the lower right side wall of the incubator 1. A louvered frame 23 is fixedly connected to the inner wall of the ventilation opening. Several rotating shafts 24, which are distributed vertically and vertically at equal distances, are rotatably connected to the inner wall of the louvered frame 23. Louvers 25 are fixedly connected to the outer walls of the rotating shafts 24. The rear ends of the rotating shafts 24 pass through the rear side wall of the louvered frame 23 and are fixedly connected to a rotating plate 29. A pull rod 26 is rotatably connected to the end of the rotating plate 29 away from the rotating shafts 24. A fixed frame 27 is fixedly connected to the rear side of the louvered frame 23. A motor 28 is fixedly connected to the rear side of the fixed frame 27. The output shaft of the motor 28 passes through the interior of the fixed frame 27 and is fixedly connected to one of the rotating shafts 24.

[0027] The controller 11 is electrically connected to the cooling fan 20, the heating wire 21, the temperature sensor 22, and the motor 28.

[0028] In some examples, two cooling fans 20 are fixedly connected to the top of the incubator 1 by screws and are arranged symmetrically on the left and right. The cooling fans 20 are DC fans DF12025B12H. Several heating wires 21 are fixedly connected to the rear inner wall of the incubator 1 by brackets. The heating wires 21 are nickel-chromium alloy heating wires, model HTL-100. Several temperature sensors 22, which are PT100 platinum resistance temperature sensors, are fixedly connected to the inner walls of both sides of the incubator 1 by bolts. A rectangular vent is opened at the bottom of the right side wall of the incubator 1. A louvered frame 23 is welded to the inner wall of the vent. Several rotating shafts 24, which are equidistant from top to bottom, are rotatably connected to the inner wall of the louvered frame 23 by bearings. Louvers 25, which are made of aluminum alloy, are fixedly connected to the outer walls of the rotating shafts 24. The rear ends of the rotating shafts 24 all penetrate to the rear wall of the louvered frame 23 and are fixedly connected by keys. There are rotating plates 29, and one end of each rotating plate 29 away from the rotating shaft 24 is rotatably connected to a pull rod 26 via a pin. The rear side wall of the louver frame 23 is fixedly connected to a fixed frame 27 by bolts. The rear side of the fixed frame 27 is fixedly connected to a motor 28 via a bracket. The output shaft of the motor 28 passes through the interior of the fixed frame 27 and is fixedly connected to one of the rotating shafts 24 via a coupling. The controller 11 is electrically connected to the cooling fan 20, the heating wire 21, the temperature sensor 22, and the motor 28 via cables. During operation, the controller 11 controls the on / off state of the heating wire 21 and the start / stop state of the cooling fan 20 based on the temperature signal detected by the temperature sensor 22 using a PID algorithm to achieve constant temperature control. At the same time, the controller 11 outputs a signal to the motor 28 according to the ventilation demand. The motor 28 drives the rotating shaft 24 to rotate, which drives all the louvers 25 to rotate synchronously through the rotating plates 29 and the pull rod 26, thereby adjusting the opening of the ventilation opening and realizing intelligent ventilation adjustment.

[0029] like Figure 4 As shown, a buffer and shock absorption assembly 3 is shown in another embodiment of the present invention. The buffer and shock absorption assembly 3 includes a hollow frame 30 and a lifting plate 32. The lifting plate 32 is fixedly connected to the bottom of the support leg 13. Slide rods 31 are fixedly connected to the top left and right sides of the lifting plate 32. Limit blocks are fixedly connected to the top of the two slide rods 31. Two left and right symmetrical sliding groove holes 35 are opened on the top of the hollow frame 30. The inner walls of the two sliding groove holes 35 are slidably connected to the outer walls of the slide rods 31 respectively.

[0030] Dampers 33 are fixedly connected to the four corners of the bottom of the lifting plate 32. The bottom of the four dampers 33 is fixedly connected to the inner bottom wall of the hollow frame 30. A buffer base plate 34 is fixedly connected to the bottom of the hollow frame 30.

[0031] In some examples, four of these components are installed at the bottom of the four support legs 13 to reduce vibration of the incubator 1 during transportation or use. The lifting plate 32 is fixedly connected to the bottom of the support legs 13 by welding. Slide rods 31 are welded to the top left and right sides of the lifting plate 32. The slide rods 31 are made of round steel. Limit blocks are welded to the top of the two slide rods 31 to prevent slippage. The top of the hollow frame 30 has two symmetrical sliding groove holes 35. The inner walls of the two sliding groove holes 35 are respectively connected to the outer walls of the slide rods 31. The sliding connection allows the lifting plate 32 to move vertically. The damper 33 is a hydraulic damper HDB-20. The bottom of the four dampers 33 is fixedly connected to the inner bottom wall of the hollow frame 30 by bolts. The bottom of the hollow frame 30 is welded with a buffer plate 34, which is made of rubber material to increase friction with the ground and absorb impact. When the incubator 1 is subjected to external vibration, the lifting plate 32 slides in the sliding groove hole 35 through the slide rod 31, and at the same time, the damper 33 provides damping force to effectively reduce vibration.

[0032] like Figures 5-7 As shown, it illustrates a shelf spacing adjustment component 4 in another embodiment of the present invention. The shelf spacing adjustment component 4 includes two equidistant adjustment mechanisms 40, which are arranged symmetrically on the left and right. Several shelf panels 41 are arranged at equal vertical distances on the opposite sides of the two equidistant adjustment mechanisms 40.

[0033] The equidistant adjustment mechanism 40 includes a fixed frame 401, which is fixedly connected to the inside of the incubator 1. Rotating rods 402 are rotatably connected to the upper and lower inner walls of the fixed frame 401. A second motor 403 is fixedly connected to the top of the fixed frame 401. The output shaft of the second motor 403 passes through the inside of the fixed frame 401 and is fixedly connected to the rotating rods 402. Four rectangular sliding columns 404 are fixedly connected to the upper and lower inner walls of the fixed frame 401. Open-type sliders 405, which are adapted to the number of placement plates 41, are slidably connected to the outer walls of the four sliding columns 404. The side of the open-type sliders 405 near the placement plates 41 has a groove 408 that is slidably connected to the placement plates 41. The outer wall of the rotating rod 402 has a spiral groove 407 that is adapted to the number of placement plates 41 and is symmetrically arranged vertically. Each of the several open-type sliders 405 near the rotating rod 402 has a limiting slider 406 that is slidably connected to the inner wall of the spiral groove 407. The controller 11 is electrically connected to the second motor 403.

[0034] In some examples, this component is located inside the incubator 1 and is used to adjust the distance between two adjacent shelf plates 41 to accommodate culture vessels of different heights. Several shelf plates 41, evenly spaced vertically, are arranged on opposite sides of the two equidistant adjustment mechanisms 40. The shelf plates 41 are made of stainless steel mesh to facilitate air circulation. Rotating rods 402 are rotatably connected to the inner walls of the upper and lower sides of the fixing frame 401 via bearings. The output shaft of the second motor 403 passes through the interior of the fixing frame 401 via a coupling and is fixedly connected to the rotating rods 402. Open-type sliders 405, matching the number of shelf plates 41, are slidably connected to the outer walls of four sliding pillars 404. The side of the open-type slider 405 closest to the shelf plate 41 has a groove 408 that slidably connects to the end of the shelf plate 41. The shelf 41 can slide horizontally, facilitating its removal. The outer wall of the rotating rod 402 is machined with spiral grooves 407 that are symmetrically arranged and matched with the number of shelf 41. The spiral grooves 407 are in the shape of an Archimedean spiral. Several open-type sliders 405 are fixedly connected to the side of the rotating rod 402 by screws to limit sliders 406 that slide on the inner wall of the spiral grooves 407. The controller 11 is electrically connected to the second motor 403 via a cable. After the user inputs the spacing command of the shelf 41 through the controller 11, the controller 11 controls the second motor 403 to rotate, which drives the rotating rod 402 to rotate. Since the limit sliders 406 slide in the spiral grooves 407, the open-type sliders 405 move up and down along the sliding column 404, thereby driving the shelf 41 to adjust the spacing synchronously.

[0035] The working principle and usage process of this invention are as follows: When intelligent temperature control and ventilation adjustment of the equipment are required, multiple temperature sensors 22 installed on the inner walls of the left and right sides of the incubator 1 monitor the temperature of each area inside the incubator in real time and transmit the temperature data signals to the controller 11. The controller 11 compares the received average temperature value with the user-preset target temperature value and calculates precise control commands through the internally integrated control algorithm. When the temperature inside the incubator is lower than the target value, the controller 11 sends an energizing command to the heating wire 21. After the heating wire 21 is energized, it heats up and heats the inside of the incubator 1, causing the temperature to rise. When the temperature inside the incubator is higher than the target value, or when rapid cooling is required, the controller 11 starts two cooling fans 20 located on the top of the incubator. The cooling fans 20 operate to force the hot air inside the incubator to be discharged, achieving active heat dissipation and lowering the temperature. This allows the temperature inside the incubator 1 to be continuously and automatically stabilized at the set constant temperature. At the same time, the controller 11 sends a forward or reverse drive signal to the motor 28 according to the temperature control requirements or the ventilation program manually set by the user. After the motor 28 starts, its output shaft directly drives a rotating... The rotation of shaft 24 causes the rotating plate 29 to rotate synchronously. The rotating plate 29, via the pull rod 26, pulls all the other rotating plates 29, thereby causing all the rotating shafts 24 to rotate synchronously and at the same angle. The rotation of all the rotating shafts 24 causes the louvers 25 fixed to them to uniformly change their tilt angle. By controlling the angle of the louvers 25 from fully closed to fully open, the opening of the louver frame 23 ventilation opening can be infinitely adjusted, thereby precisely controlling the fresh air volume entering the incubator 1 or the rate of exhaust gas discharge. This invention, through the setting of temperature control and intelligent ventilation adjustment groups… Component 2 utilizes multi-point distributed temperature sensors, enabling the system to comprehensively and in real-time perceive the temperature at different locations within the incubator. This avoids blind spots or errors that may exist in single-point temperature measurement. Based on this real-time data, the controller can precisely direct the heating elements and cooling fans to work together, quickly compensating for or suppressing minor temperature fluctuations. This keeps the temperature fluctuation range of the entire working chamber within a very small range, providing a crucial constant environment for temperature-sensitive culture samples. Simultaneously, by precisely controlling the opening and closing angle of the louvers through a motor, the ventilation volume can be finely controlled, providing active and controllable ventilation assurance.

[0036] When the spacing between the shelves needs to be adjusted, the user inputs the command to adjust the shelf spacing through the controller 11. The controller 11 controls the two motors 403 to start and rotate synchronously. The motors 403 drive the rotating rod 402 to rotate. Since the limiting slider 406 is nested in the spiral groove 407 on the surface of the rotating rod 402, when the rotating rod 402 rotates, the inclined surface of the spiral groove 407 will push the limiting slider 406 to produce vertical displacement. Each limiting slider 406 is fixed on an open slider 405, and the open slider 405 is fitted on the vertical sliding post 404, so it can only slide up and down. In this way, all the open-type sliders 405 will move up and down according to the trajectory of the spiral groove 407, so that the distance between all the shelves 41 is increased or decreased synchronously and equally, realizing efficient and flexible use of space. Through the shelf spacing adjustment component 4, the user can freely and accurately adjust the vertical distance between each shelf according to the actual height of the current culture vessel (e.g., from short culture vessels to tall conical flasks), so that the internal space of the incubator can be fully utilized, avoiding the space waste caused by fixed shelf height, and greatly expanding the application range of the equipment.

[0037] When the incubator is subjected to external vibration or impact, the force is transmitted to the lifting plate 32 through the support leg 13. The lifting plate 32 moves downwards under pressure, causing the slide rod 31 to slide downwards along the sliding groove hole 35. This design ensures the verticality of the movement and prevents jamming. Simultaneously, multiple dampers 33 connected to the bottom of the lifting plate 32 and the hollow frame 30 are compressed. During compression and rebound, the dampers 33 generate a strong damping force, converting the impact kinetic energy into heat energy and dissipating it, thereby quickly suppressing the vertical vibration of the lifting plate 32. Finally, the shock absorber base plate 34 flattens the incubator. The stable force is transmitted to the ground, effectively protecting the safety of the precision components and culture samples inside the incubator 1. Through the buffer and shock absorption component 3, the present invention effectively absorbs and isolates vibrations from the external environment or internal vibrations during the operation of the incubator, providing an extremely stable static or quasi-static environment for vibration-sensitive cultures such as cells, microorganisms, and plant seedlings. This avoids problems such as poor cell adhesion, abnormal colony morphology, and physical damage caused by vibration, fundamentally ensuring the accuracy and reproducibility of experimental results.
