Description

Technical Field

[0001] The invention relates to the technical field of biochemical incubators, in particular to a biochemical incubator with adjustable temperature and humidity. Background Art

[0002] A biochemical incubator is a professional device used for biological and chemical experiments and research. Its main function is to precisely control the internal temperature and humidity environment. It is required when the molecular biological information analysis and processing system is analyzing and processing organisms.

[0003] When an incubator is operating, air flow rates and directions vary across different areas, leading to uneven distribution of temperature and humidity within the chamber. For example, areas near the temperature and humidity control mechanism may experience rapid and precise temperature and humidity changes, while areas further away from the mechanism experience slower temperature and humidity regulation. This is detrimental to the cultivation of biological samples, which are extremely sensitive to environmental conditions, and can lead to deviations in culture results, compromising the accuracy and reliability of experiments.

[0009] Preferably, the humidifying mechanism includes a support plate 2, the outer surface of the support plate 2 is fixedly connected to a connecting plate, the outer surface of the connecting plate is fixedly connected to a servo motor 3, the output end of the servo motor 3 is fixedly connected to a rotating shaft, and one end of the rotating shaft is fixedly connected to a wet film synthesized from a highly water-absorbent material.

[0010] Preferably, the support plate 2 is arranged on the outer surface of the rotating hollow tube, and the water sprayed by the nozzle will keep the wet film moist.

[0014] The beneficial effects of the present invention are as follows: 1. The present invention provides an air duct unit. After the air is heated and enters the main air duct through the air outlet, the cross-sectional area of the air duct gradually increases from the heating device connection end to the remote end. In this way, the flow velocity of the gas output from the regulating device gradually decreases when flowing in the main air duct, and the pressure distribution is more uniform, thereby ensuring that the gas flow rate and pressure entering each branch air duct are relatively consistent.

[0015] 2. The present invention sets a branch unit, and the servo motor will drive the reciprocating screw to rotate, thereby realizing the movement of the moving block, and then driving 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 to flow to the area with uneven temperature distribution, and promoting uniform mixing of the gas in the incubator.

[0016] 3. The present invention provides a humidifying unit. The nozzle sprays water onto the wet membrane with a small impact force, so that the wet membrane always remains 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 membrane, the water evaporates into the gas, thereby increasing the humidity of the gas. By adjusting the water supply of the nozzle and the speed of the gas flowing through the wet membrane, the humidity can be effectively regulated.

[0017] 4. The present invention is provided with a humidifying mechanism. As the air passes through the wet membrane for a long time, a layer of dirt in the air will be produced on the side of the wet membrane that first contacts the air, which will affect its humidification efficiency and the environment inside the incubator. Therefore, every once in a while, the servo motor 3 will drive the rotating shaft and the wet membrane to rotate, so that the side with the stains faces the nozzle. The water flow sprayed by the nozzle will increase at this time, thereby washing away the stains. The stains will enter the collection plate with the water flow, which is convenient for subsequent cleaning.

[0018] 4. The present invention sets a release mechanism, and the magnetic cover moves upward along the support rod, so that the humidified air flows out of the rotating hollow tube. At the same time, the micro motor drives the fan to rotate, so that the humid air circulates upward and does not directly contact the cultured organisms, avoiding excessive saturation of water vapor, which may cause bacterial aggregation and the breeding of miscellaneous bacteria.

[0019] 5. The present invention provides a holding unit. As the servo motor 2 drives the rotating hollow tube to rotate slowly, it also drives the support rod 2 to rotate, thereby driving the holding plate where the cultured organisms are placed to rotate, so that the culture moves in a cycle in the incubator, avoiding the same culture always being in different positions with different temperature, which would cause errors in molecular biological information analysis and processing.

DETAILED DESCRIPTION

[0033] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0034] Example 1: Use Figures 1-12 A biochemical incubator with adjustable temperature and humidity according to one embodiment of the present invention is described below.

[0035] like Figure 1-Figure 2 As shown, a biochemical incubator with adjustable temperature and humidity of the present invention comprises a box body 1, a sealed door 2 that can be opened and closed is provided on the front of the box body 1, a console 3 is fixedly connected to the outer surface of the box body 1, and a thermal insulation layer 4 is evenly provided on the inner wall of the box body 1, and further comprises: The heating unit 5 is used to absorb air and heat the air; 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; Humidification unit 7, used to control the humidity in the incubator; The heating unit 5 is arranged on the outer surface of the box body 1, the air duct unit 6 is arranged on the top of the heating unit 5, and the humidifying unit 7 is arranged on the inner wall of the box body 1; When the present invention is working, the culture is first placed in the humidification unit 7, then the sealed 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.

[0036] like Figure 5 As shown, the air duct unit 6 includes a main air duct 61. A plurality of vertical branch units 62 are provided at the bottom of the main air duct 61 and communicate with the internal space of the incubator. The cross-sectional area of the main air duct 61 gradually increases. The outer surface of the branch unit 62 is evenly provided with support plates 64 from top to bottom. The outer surface of the support plate 64 is provided with a temperature sensor 65 and a humidity sensor 63 for detecting whether there is a difference in temperature and humidity at each height of the incubator. The provision of a large number of temperature sensors 65 and humidity sensors 63 is to avoid failure of some sensors and to more accurately detect the temperature and humidity at each height in the incubator. After the air is heated and enters the main air duct 61 through the air outlet end 53, the cross-sectional area of the air duct gradually increases from the connection end of the heating device 54 to the distal end. This allows the gas output from the regulating device to flow in the main air duct 61. The flow velocity gradually decreases and the pressure distribution becomes more uniform, thereby ensuring that the gas flow and pressure entering each branch air duct 621 are relatively consistent.

[0037] like Figure 6 As shown, the branch unit 62 includes a branch air duct 621, and the branch air duct 621 is evenly provided with notches 625 for discharging gas. The bottom of the branch air duct 621 is fixedly connected to a servo motor 622, and the output end of the servo motor 622 is fixedly connected to a reciprocating screw 623. The outer surface of the reciprocating screw 623 is threadedly connected to a moving block 624, and an air outlet blade 626 is rotatably connected to the notch 625. The air outlet blade 626 is rotatably connected to a rotating column 627 on the side close to the moving block 624, and the outer surface of the moving block 624 is fixedly connected to a support rod 628.

[0038] When the temperature sensors 65 at different heights detect that the temperature difference exceeds the set value, the built-in controller will send an instruction to the servo motor 622, and the servo motor 622 will drive the reciprocating screw 623 to rotate. This control process is a conventional means of temperature and humidity sensing control under the existing technology.

[0039] According to the actual needs of different areas in the incubator, the angle of the air outlet blade 626 can be adjusted to change the air outlet direction of the gas, guide the gas to the area with uneven temperature and humidity distribution, and promote uniform mixing of the gas in the incubator.

[0040] The branch air duct 621 is provided at the bottom of the main air duct 61 , and one end of the support rod 628 away from the moving block 624 is fixedly connected to the outer surface of the rotating column 627 .

[0041] The entire incubator will be 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 in the incubator is uneven, the servo motor 622 will drive the reciprocating screw 623 to rotate, thereby enabling the moving block 624 to move, and then drive 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 lower temperature, guiding the gas to flow to the area with uneven temperature distribution, and promoting uniform mixing of the gas in the incubator.

[0042] 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 driving the air outlet blades 626 to rotate downward, so that the hot air flows toward the bottom of the incubator.

[0043] like Figure 3-Figure 4 As shown, the heating unit 5 includes an air aspirator 51, an air inlet 52 is provided on the outer surface of the air aspirator 51, a heating device 54 is provided on the inner wall of the air aspirator 51, and heat-conducting columns 55 are symmetrically provided on the top of the heating device 54 for heating the air.

[0044] The specific workflow is as follows: During operation, the air suction machine 51 will inhale air from the outside and heat the air through the heating device 54 and the heat-conducting column 55. After the air is heated and enters the main air duct 61 through the air outlet 53, the airflow enters the branch air duct 621. If the temperature sensor 65 and the humidity sensor 63 detect that the temperature distribution in the incubator is uneven, the servo motor 622 will drive the reciprocating screw 623 to rotate, thereby realizing the movement of the moving block 624, and then 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 lower temperature.

[0045] Example 2: Use Figures 1-12 A biochemical incubator with adjustable temperature and humidity according to one embodiment of the present invention is described below.

[0046] like Figure 8-Figure 9As shown, a biochemical incubator with adjustable temperature and humidity of the present invention, based on embodiment one, the humidifying unit 7 includes a servo motor 2 71, the output end of the servo motor 2 71 is fixedly connected to a rotating hollow tube 72, the end of the rotating hollow tube 72 away from the servo motor 2 71 is fixedly connected to a rotating block 73, and the end of the rotating hollow tube 72 close to the rotating block 73 is provided with an exhaust fan 74, and the inner wall of the rotating hollow tube 72 is also provided with a water storage pipe 78, the outer surface of the water storage pipe 78 is provided with a detachable water inlet cover 79, a water pipe 710 is provided on one side of the water storage pipe 78, and the end of the water pipe 710 away from the water storage pipe 78 is fixedly connected to a water spraying device 711, the outer surface of the water spraying device 711 is evenly provided with nozzles 712 that can control the size of the water flow, and the bottom of the water spraying device 711 is fixedly connected to a collecting plate 713 for collecting impurities.

[0047] Before the incubator is operational, clean water must be added to the outlet pipe 710. The water then flows through the pipe 710 into the water spray device 711. The nozzle 712 sprays the water onto the wet membrane 775 with minimal force, keeping the wet membrane 775 moist at all times. The dry gas within the incubator is drawn into the rotating hollow tube 72 by the vacuum pump 74 and passes through the wet membrane 775, increasing the humidity of the gas. The humidified air then passes through the wet membrane 775 and flows toward the center of the rotating hollow tube 72, facilitating the subsequent release of the humidified air by the release mechanism. By adjusting the water supply from the nozzle 712 and the speed at which the gas flows through the wet membrane 775, effective humidity regulation can be achieved. This method of humidity regulation eliminates the need for increasing humidity by evaporating water, as this would not only affect the humidity but also cause the temperature to change, potentially causing errors in the temperature regulation of the heating unit 5 and the air duct unit 6.

[0048] The humidifying unit 7 also includes: A holding mechanism 75 is used to place the desired cultured organisms; a release mechanism 76 for releasing air with humidity; The humidifying mechanism 77 is used to humidify the dry air.

[0049] like Figure 10 As shown, the humidifying mechanism 77 includes a second support plate 771, the outer surface of the second support plate 771 is fixedly connected to a connecting plate 772, the outer surface of the connecting plate 772 is fixedly connected to a servo motor 3 773, the output end of the servo motor 3 773 is fixedly connected to a rotating shaft 774, and one end of the rotating shaft 774 is fixedly connected to a wet film 775 synthesized from a highly water-absorbing material.

[0050] As air passes through the wet membrane 775 for a long time, a layer of dirt in the air will form on the side of the wet membrane 775 that first contacts the air, which will affect its humidification efficiency and the environment inside the incubator. Therefore, every once in a while, the servo motor 773 will drive the rotating shaft 774 and the wet membrane 775 to rotate, so that the side with the stains faces the nozzle 712. The water flow sprayed by the nozzle 712 will increase at this time, thereby washing away the stains. The stains will enter the collection plate 713 with the water flow, which is convenient for subsequent cleaning.

[0051] The second support plate 771 is set on the outer surface of the rotating hollow tube 72. The water sprayed by the nozzle 712 will keep the wet film 775 in a wet state. 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.

[0052] like Figure 11 As shown, the release mechanism 76 includes a support rod 761, the outer surface of the support rod 761 is slidably connected to a magnetic cover 762, support plates 763 are symmetrically arranged at both ends of the magnetic cover 762, the bottom of the support plate 763 is fixedly connected to a micro motor 764, the output end of the micro motor 764 is fixedly connected to a fan 765, and telescopic springs 766 are symmetrically arranged at both ends of the magnetic cover 762.

[0053] Only when the containing mechanism 75 moves to the top, the distance between the magnetic block 755 and the magnetic cover 762 is the shortest, so that the magnetic force between them will 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, a gap will appear in the originally sealed rotating hollow tube 72, allowing the humidified air to flow out from the gap on the rotating hollow tube 72. At the same time, the micro motor 764 will drive the fan 765 to rotate, so that the humid air will circulate upward and will not directly contact the cultured organisms, avoiding excessive saturation of water vapor, which may cause bacterial aggregation and the breeding of miscellaneous bacteria.

[0054] One end of the support rod 1 761 is fixedly connected to the outer surface of the rotating hollow tube 72 , and one end of the telescopic spring 766 away from the magnetic cover 762 is fixedly connected to the outer surface of the support rod 1 761 .

[0055] like Figure 12 As shown, the holding mechanism 75 includes a second support rod 751, the outer surface of the second support rod 751 is rotatably connected to a rotating sleeve 752, the outer surface of the rotating sleeve 752 is evenly provided with third support rods 753, and the end of the third support rod 753 away from the rotating sleeve 752 is fixedly connected to a holding plate 754, the bottom of the holding plate 754 is fixedly connected to a magnetic block 755 attracted to the magnetic cover 762, and the top of the holding plate 754 is fixedly connected to a culture dish tray 756; Although the air duct unit 6 is provided to adjust the temperature at the top and bottom of the incubator, the temperature adjustment cannot be completed instantly. Therefore, the servo motor 2 71 drives the rotating hollow tube 72 to rotate slowly, which also drives the support rod 2 751 to rotate, thereby driving the plate 754 for placing the cultured organisms to rotate, so that the culture circulates in the incubator, avoiding the same culture always being in different positions with different temperatures, causing errors in the molecular biological information analysis and processing.

[0056] One end of the second support rod 751 is fixedly connected to the outer surface of the rotating hollow plate.

[0057] The specific workflow is as follows: During operation, the servo motor 2 71 drives the rotating hollow tube 72 to rotate slowly, and also drives the support rod 2 751 to rotate, thereby driving the plate 754 on which the cultured organisms are placed to rotate, so that the cultured organisms circulate in the incubator. The water source enters the water spray device 711 through the water pipe 710, and the nozzle 712 sprays the water flow onto the wet film 775 with a small impact force, so that the wet film 775 is always kept wet. When the dry gas flow in the incubator is drawn into the rotating hollow tube 72 by the exhaust fan 74 and passes through the wet film 775, the dry gas flow increases. To increase the humidity of the gas, the servo motor 3 773 will drive the rotating shaft 774 and the wet film 775 to rotate at regular intervals, so that the side with the stain is facing the nozzle 712. The water flow sprayed by the nozzle 712 will increase at this time, thereby washing away the stains. When the containing mechanism 75 moves to the top, the magnetic cover 762 will move upward along the support rod 1 761, so that the humidified air flows out from the rotating hollow tube 72. At the same time, the micro motor 764 will drive the fan 765 to rotate, so that the humid air circulates upward and will not directly contact the cultured organisms.

[0058] Obviously, the embodiments described are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative work should fall within the scope of protection of the present invention.
