Description

Technical Field

[0001] This invention relates to the field of biochemical incubator technology, specifically to a biochemical incubator with adjustable temperature and humidity. Background Technology

[0002] A biochemical incubator is a specialized piece of equipment used in biological and chemical experiments and research. Its main function is to precisely control the internal temperature and humidity environment. Biochemical incubators are required when molecular biological information analysis and processing systems analyze and process biological data.

[0003] When an incubator is operating, differences in gas flow rate and direction in different areas lead to uneven distribution of temperature and humidity within the chamber. For example, areas near the temperature and humidity control devices may experience rapid and precise temperature and humidity changes, while corner areas far from these devices may experience relatively slower temperature and humidity regulation. This is extremely detrimental to the culture of biological samples that are highly sensitive to environmental conditions, potentially causing deviations in culture results and affecting the accuracy and reliability of the experiment. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention is as follows: A temperature and humidity adjustable biochemical incubator, comprising a chamber body, a sealable door that can be opened and closed on the front of the chamber body, a control console fixedly connected to the outer surface of the chamber body, and a uniformly distributed heat insulation layer on the inner wall of the chamber body, further comprising:

[0005] The heating unit is used to draw in air and heat it to a higher temperature.

[0006] The air duct unit is used to transmit the air heated by the heating unit and control the flow of hot air;

[0007] Humidification unit, used to control the humidity in the incubator;

[0008] The heating unit is located on the outer surface of the housing, the air duct unit is located on top of the heating unit, and the humidification unit is located on the inner wall of the housing.

[0009] The air duct unit includes a main air duct, and the bottom of the main air duct is provided with multiple vertical branch units that are connected to the internal space of the incubator. The cross-sectional area of ​​the main air duct gradually increases. The outer surface of the branch unit is uniformly provided with a support plate from top to bottom. The outer surface of the support plate is provided with a temperature sensor and a humidity sensor to detect whether there are differences in temperature and humidity at each height of the incubator.

[0010] The branch unit includes a branch air duct with evenly distributed notches for exhausting gas. A servo motor is fixedly connected to the bottom of the branch air duct, and a reciprocating lead screw is fixedly connected to the output end of the servo motor. A moving block is threadedly connected to the outer surface of the reciprocating lead screw. An air outlet blade is rotatably connected to the notch, and a rotating column is rotatably connected to the side of the air outlet blade near the moving block. A support rod is fixedly connected to the outer surface of the moving block.

[0011] Preferably, the angle of the air outlet blades can be adjusted according to the actual needs of different areas in the incubator to change the direction of gas flow, guide the gas flow to areas with uneven temperature and humidity distribution, and promote uniform mixing of gas in the incubator.

[0012] Preferably, the branch air duct is located at the bottom of the main air duct, and the end of the support rod away from the moving block is fixedly connected to the outer surface of the rotating column.

[0013] Preferably, the heating unit includes an air intake, an air inlet is provided on the outer surface of the air intake, a heating device is provided on the inner wall of the air intake, and heat-conducting columns are symmetrically arranged on the top of the heating device for heating air.

[0014] Preferably, the humidification unit includes a second servo motor, the output end of which is fixedly connected to a rotating hollow tube. A rotating block is fixedly connected to the end of the rotating hollow tube away from the second servo motor. An air pump is installed at the end of the rotating hollow tube near the rotating block. A water storage pipe is also provided on the inner wall of the rotating hollow tube. A removable water inlet cap is provided on the outer surface of the water storage pipe. A water pipe is provided on one side of the water storage pipe. A water spraying device is fixedly connected to the end of the water pipe away from the water storage pipe. Spray nozzles that can control the water flow are evenly arranged on the outer surface of the water spraying device. A collection plate is fixedly connected to the bottom of the water spraying device for collecting impurities. The humidification unit also includes:

[0015] A container used to hold the organisms to be cultured;

[0016] A release mechanism for releasing humidified air;

[0017] A humidifier is used to humidify dry air.

[0018] Preferably, the humidification mechanism includes a second support plate, a connecting plate fixedly connected to the outer surface of the second support plate, a third servo motor fixedly connected to the outer surface of the connecting plate, a rotating shaft fixedly connected to the output end of the third servo motor, and a wet film made of a highly absorbent material fixedly connected to one end of the rotating shaft.

[0019] Preferably, the second support plate is disposed on the outer surface of the rotating hollow tube. The water sprayed from the nozzle keeps the wet film moist. When the dry gas in the incubator flows through the wet film, the water evaporates into the gas, thereby increasing the humidity of the gas.

[0020] Preferably, the release mechanism includes a support rod, a magnetic cover is slidably connected to the outer surface of the support rod, support plates are symmetrically arranged at both ends of the magnetic cover, a micro motor is fixedly connected to the bottom of the support plate, a fan is fixedly connected to the output end of the micro motor, and telescopic springs are symmetrically arranged at both ends of the magnetic cover.

[0021] Preferably, one end of the support rod is fixedly connected to the outer surface of the rotating hollow tube, and the end of the telescopic spring away from the magnetic cover is fixedly connected to the outer surface of the support rod.

[0022] Preferably, the holding mechanism includes a second support rod, a rotating sleeve rotatably connected to the outer surface of the second support rod, a third support rod evenly distributed on the outer surface of the rotating sleeve, a holding plate fixedly connected to the end of the third support rod away from the rotating sleeve, a magnetic block attracted to the magnetic cover fixedly connected to the bottom of the holding plate, and a culture dish fixedly connected to the top of the holding plate.

[0023] One end of the second support rod is fixedly connected to the outer surface of the rotating hollow tube.

[0024] The beneficial effects of this invention are as follows:

[0025] 1. By setting up a duct unit, after the air is heated and enters the main duct through the outlet, the cross-sectional area of ​​the duct gradually increases from the connection end of the heating device to the far end. This allows the flow velocity of the gas output from the regulating device to gradually decrease and the pressure distribution to be more uniform when it flows in the main duct, thereby ensuring that the gas flow rate and pressure entering each branch duct are relatively consistent.

[0026] 2. By setting up a branch unit, the servo motor will drive the reciprocating screw to rotate, thereby enabling the moving block to move. This, in turn, drives the support rod to pull the rotating column and the air outlet blades to rotate, so that the air outlet blades face the layer with lower temperature, guiding the gas flow to the area with uneven temperature distribution and promoting uniform mixing of gas in the incubator.

[0027] 3. This invention, by setting up a humidification unit, sprays water onto the wet film with a small impact force, thereby keeping the wet film constantly moist. When the dry gas flow in the incubator is drawn into the rotating hollow tube by the vacuum pump and passes through the wet film, the water will evaporate into the gas, thereby increasing the humidity of the gas. By adjusting the water supply of the nozzle and the speed of the gas flow through the wet film, the humidity can be effectively regulated.

[0028] 4. By setting up a humidification mechanism, as air passes through the wet film for a long time, a layer of airborne dirt will be generated on the side of the wet film that first comes into contact with the air, which will affect its humidification efficiency and the environment inside the incubator. Therefore, every once in a while, the servo motor will drive the rotating shaft and the wet film to rotate, so that the side with the dirt is facing the nozzle. The water flow from the nozzle will increase at this time, thereby washing away the dirt. The dirt will enter the collection plate with the water flow, which will facilitate subsequent cleaning.

[0029] 4. By setting a release mechanism, the magnetic cover will move upward along the support rod, allowing the humidified air to flow out from the rotating hollow tube. At the same time, the micro motor will drive the fan to rotate, causing the humid air to circulate upward and not directly contact the cultured organisms. This avoids the problem of water vapor oversaturation, which may lead to bacterial aggregation and the growth of miscellaneous bacteria.

[0030] 5. By setting up a holding unit, the servo motor drives the rotating hollow tube to rotate slowly, which in turn drives the support rod to rotate, thereby rotating the holding plate on which the cultured organism is placed. This allows the culture to circulate and move within the incubator, preventing the same culture from always being in different positions with different temperatures, which could cause errors in molecular biological information analysis and processing.

[0044] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0045] Example 1, using Figures 1-12 The following describes a temperature and humidity adjustable biochemical incubator according to one embodiment of the present invention.

[0046] like Figures 1-2 As shown, a temperature and humidity adjustable biochemical incubator of the present invention includes a chamber body 1, a sealable door 2 that can be opened and closed is provided on the front of the chamber body 1, a control console 3 is fixedly connected to the outer surface of the chamber body 1, and a heat insulation layer 4 is uniformly provided on the inner wall of the chamber body 1. It also includes:

[0047] Heating unit 5 is used to draw in air and heat the air to a higher temperature.

[0048] The air duct unit 6 is used to transmit the air heated by the heating unit 5 and control the flow of the hot air;

[0049] Humidification unit 7 is used to control the humidity in the incubator;

[0050] Heating unit 5 is located on the outer surface of housing 1, air duct unit 6 is located on top of heating unit 5, and humidification unit 7 is located on the inner wall of housing 1.

[0051] When the present invention is in operation, the culture is first placed in the humidification unit 7, then the sealing door 2 is closed, the heating unit 5 is started to heat the air, the air duct unit 6 controls the hot air to circulate in the incubator and adjusts the temperature, and finally the humidification unit 7 adjusts the humidity in the incubator.

[0052] like Figure 5 As shown, the air duct unit 6 includes a main air duct 61. The bottom of the main air duct 61 is provided with multiple vertical branch units 62 that are connected to the internal space of the incubator. The cross-sectional area of ​​the main air duct 61 gradually increases. Support plates 64 are evenly provided on the outer surface of the branch units 62 from top to bottom. Temperature sensors 65 and humidity sensors 63 are provided on the outer surface of the support plates 64 to detect whether there are differences in temperature and humidity at each height of the incubator. The purpose of providing a large number of temperature sensors 65 and humidity sensors 63 is to avoid the failure of some sensors and to more accurately detect the temperature and humidity at each height of the incubator.

[0053] After the air is heated and enters the main air duct 61 through the outlet 53, the cross-sectional area of ​​the air duct gradually increases from the connection end of the heating device 54 to the far end. This allows the gas output from the regulating device to flow in the main air duct 61 with a gradually decreasing flow velocity and a more uniform pressure distribution, thereby ensuring that the gas flow rate and pressure entering each branch air duct 621 are relatively consistent.

[0054] like Figure 6 As shown, the branch unit 62 includes a branch air duct 621. Notches 625 are evenly arranged on the branch air duct 621 for discharging gas. A servo motor 622 is fixedly connected to the bottom of the branch air duct 621. A reciprocating screw 623 is fixedly connected to the output end of the servo motor 622. A moving block 624 is threadedly connected to the outer surface of the reciprocating screw 623. An air outlet blade 626 is rotatably connected to the notch 625. A rotating column 627 is rotatably connected to the side of the air outlet blade 626 near the moving block 624. A support rod 628 is fixedly connected to the outer surface of the moving block 624.

[0055] When the temperature sensor 65 at different heights detects a temperature difference exceeding the set value, the built-in controller sends a command to the servo motor 622, which then drives the reciprocating screw 623 to rotate. This control process is a conventional method for temperature and humidity sensing control in the existing technology.

[0056] The angle of the air outlet blades 626 can be adjusted according to the actual needs of different areas in the incubator to change the direction of gas flow, guide the gas to areas with uneven temperature and humidity distribution, and promote uniform mixing of gas in the incubator.

[0057] Branch air duct 621 is located at the bottom of main air duct 61, and the end of support rod 628 away from moving block 624 is fixedly connected to the outer surface of rotating column 627.

[0058] The incubator is divided into a top layer and a bottom layer. After the airflow enters the branch air duct 621, if the temperature sensor 65 and the humidity sensor 63 detect that the temperature distribution inside the incubator is uneven, the servo motor 622 will drive the reciprocating screw 623 to rotate, which will in turn move the moving block 624, thereby driving the support rod 628 to pull the rotating column 627 and the air outlet blade 626 to rotate, so that the air outlet blade 626 faces the layer with a lower temperature, guiding the gas flow to the area with uneven temperature distribution and promoting the uniform mixing of gas in the incubator.

[0059] For example, when the temperature difference between the bottom temperature sensor 65 and the top temperature is large, the servo motor 622 will drive the reciprocating screw 623 to rotate, thereby driving the moving block 624 to move downward and causing the air outlet blades 626 to rotate downward, so that hot air flows towards the bottom of the incubator.

[0060] like Figures 3-4 As shown, the heating unit 5 includes an air intake 51, an air inlet 52 is provided on the outer surface of the air intake 51, a heating device 54 is provided on the inner wall of the air intake 51, and heat-conducting columns 55 are symmetrically arranged on the top of the heating device 54 for heating air.

[0061] The specific workflow is as follows:

[0062] During operation, the air intake 51 draws in outside air and heats it through the heating device 54 and the heat-conducting column 55. After the air is heated, it enters the main air duct 61 through the air outlet 53 and then enters the branch air duct 621. If the temperature sensor 65 and the humidity sensor 63 detect that the temperature distribution inside the incubator is uneven, the servo motor 622 will drive the reciprocating screw 623 to rotate, which will move the moving block 624. This will then drive the support rod 628 to pull the rotating column 627 and the air outlet blades 626 to rotate, so that the air outlet blades 626 face the layer with the lower temperature.

[0063] Example 2, using Figures 1-12 The following describes a temperature and humidity adjustable biochemical incubator according to one embodiment of the present invention.

[0064] like Figures 8-9 As shown, the present invention provides a temperature and humidity adjustable biochemical incubator. Based on Embodiment 1, the humidification unit 7 includes a servo motor 71. The output end of the servo motor 71 is fixedly connected to a rotating hollow tube 72. A rotating block 73 is fixedly connected to the end of the rotating hollow tube 72 away from the servo motor 71. An air extractor 74 is provided at the end of the rotating hollow tube 72 near the rotating block 73. A water storage pipe 78 is also provided on the inner wall of the rotating hollow tube 72. A removable water inlet cover 79 is provided on the outer surface of the water storage pipe 78. A water pipe 710 is provided on one side of the water storage pipe 78. A water spraying device 711 is fixedly connected to the end of the water pipe 710 away from the water storage pipe 78. The outer surface of the water spraying device 711 is uniformly provided with nozzles 712 that can control the water flow. A collection plate 713 is fixedly connected to the bottom of the water spraying device 711 for collecting impurities.

[0065] Before the incubator begins operation, clean water needs to be added to the outlet pipe 710. The water then flows through the pipe to the spray device 711, where the nozzle 712 sprays water onto the wet film 775 with a small impact force, keeping the film constantly moist. When the dry gas flow inside the incubator is drawn into the rotating hollow tube 72 by the vacuum pump 74 and passes through the wet film 775, the humidity of the gas increases. The humidified air then passes through the wet film 775 and flows to the center of the rotating hollow tube 72, facilitating the release of the humidified air by the subsequent release mechanism. By adjusting the water supply from the nozzle 712 and the speed of the gas flow through the wet film 775, effective humidity control can be achieved. This method of humidity control eliminates the need for evaporation, as steam not only affects humidity but also alters temperature, causing errors in temperature regulation by the heating unit 5 and the air duct unit 6.

[0066] Humidification unit 7 also includes:

[0067] The holding mechanism 75 is used to hold the organisms to be cultured;

[0068] Release mechanism 76 is used to release humidified air;

[0069] Humidification unit 77 is used to humidify dry air.

[0070] like Figure 10As shown, the humidification mechanism 77 includes a second support plate 771, a connecting plate 772 is fixedly connected to the outer surface of the second support plate 771, a third servo motor 773 is fixedly connected to the outer surface of the connecting plate 772, a rotating shaft 774 is fixedly connected to the output end of the third servo motor 773, and a wet film 775 made of a highly absorbent material is fixedly connected to one end of the rotating shaft 774.

[0071] As air passes through the wet membrane 775 for an extended period, a layer of airborne dirt will form on the side of the wet membrane 775 that first comes into contact with the air. This will affect its humidification efficiency and the environment inside the incubator. Therefore, every so often, the servo motor 773 will drive the rotating shaft 774 and the wet membrane 775 to rotate, so that the side with the dirt is facing the nozzle 712. At this time, the water flow from the nozzle 712 will increase, thereby washing away the dirt. The dirt will then enter the collection plate 713 with the water flow for easy cleaning later.

[0072] Support plate 2 771 is set on the outer surface of the rotating hollow tube 72. The water sprayed by nozzle 712 keeps the wet film 775 moist. When the dry gas in the incubator flows through the wet film 775, the water will evaporate into the gas, thereby increasing the humidity of the gas.

[0073] like Figure 11 As shown, the release mechanism 76 includes a support rod 761, a magnetic cover 762 is slidably connected to the outer surface of the support rod 761, a support plate 763 is symmetrically arranged at both ends of the magnetic cover 762, a micro motor 764 is fixedly connected to the bottom of the support plate 763, a fan 765 is fixedly connected to the output end of the micro motor 764, and a telescopic spring 766 is symmetrically arranged at both ends of the magnetic cover 762.

[0074] Only when the holding mechanism 75 moves to the top, at which point the magnetic block 755 and the magnetic cover 762 are closest, will the magnetic force between them be greater than the elastic force of the telescopic spring 766. At this time, the magnetic cover 762 will move upward along the support rod 761. After the magnetic cover 762 moves upward, there will be a gap in the originally sealed rotating hollow tube 72, allowing the humidified air to flow out through the gap in the rotating hollow tube 72. At the same time, the micro motor 764 will drive the fan 765 to rotate, causing the humid air to circulate upward and not directly contact the cultured organisms, thus avoiding the problem of water vapor oversaturation, which may lead to bacterial aggregation and the growth of miscellaneous bacteria.

[0075] One end of the support rod 761 is fixedly connected to the outer surface of the rotating hollow tube 72, and the end of the telescopic spring 766 away from the magnetic cover 762 is fixedly connected to the outer surface of the support rod 761.

[0076] like Figure 12As shown, the holding mechanism 75 includes a second support rod 751, a rotating sleeve 752 is rotatably connected to the outer surface of the second support rod 751, a third support rod 753 is evenly arranged on the outer surface of the rotating sleeve 752, a holding plate 754 is fixedly connected to the end of the third support rod 753 away from the rotating sleeve 752, a magnetic block 755 that attracts the magnetic cover 762 is fixedly connected to the bottom of the holding plate 754, and a culture dish 756 is fixedly connected to the top of the holding plate 754.

[0077] Although the air duct unit 6 is set up to adjust the temperature at the top and bottom of the incubator, the temperature adjustment cannot be completed instantly. Therefore, the servo motor 71 drives the rotating hollow tube 72 to rotate slowly, which also drives the support rod 751 to rotate, thereby driving the holding plate 754 on which the cultured organisms are placed to rotate. This allows the culture to circulate and move in the incubator, avoiding the same culture from always being in a position with different temperatures, which would cause errors in molecular biological information analysis and processing.

[0078] One end of the support rod 751 is fixedly connected to the outer surface of the rotating hollow tube 72.

[0079] The specific workflow is as follows:

[0080] During operation, servo motor 71 drives the rotating hollow tube 72 to rotate slowly, which in turn drives the support rod 751 to rotate, thereby rotating the holding plate 754 on which the cultured organisms are placed. This causes the culture to circulate within the incubator. Water enters the spray device 711 through water pipe 710, and nozzle 712 sprays water onto the wet film 775 with a small impact force, keeping the wet film 775 constantly moist. When the dry gas flow in the incubator is drawn into the rotating hollow tube 72 by the vacuum pump 74 and passes through the wet film 775, it increases... To increase the humidity of the gas, at regular intervals, the servo motor 773 drives the rotating shaft 774 and the wet film 775 to rotate, so that the side with the stains faces the nozzle 712. The water flow from the nozzle 712 increases at this time, thereby washing away the stains. When the holding mechanism 75 moves to the top, the magnetic cover 762 moves upward along the support rod 761, allowing the humidified air to flow out from the rotating hollow tube 72. At the same time, the micro motor 764 drives the fan 765 to rotate, so that the humid air circulates upward and does not directly contact the cultured organisms.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
