Description

Technical Field

[0002] A biochemical constant temperature incubator with a sterilization function is an advanced experimental equipment, specially designed for biochemical research and microbial culture. It can provide a stable and precise temperature environment (this is artificially controlled temperature adjustment, and it is not the innovation of the present invention, so it does not need to be specifically explained). It can usually be set and adjusted within a wide temperature range to meet the growth requirements of different cultures. This biochemical constant temperature incubator with a sterilization function is widely used in research and production activities such as microbial culture, cell culture, seed germination test in the fields of medicine, biology, agriculture, food science, etc., providing a reliable guarantee for scientific research and experimental work.

[0003] Due to the different temperatures between the incubator and the outside world, the air pressure generated is also different (there is a difference in air pressure, but it will not affect growth).

[0013] The beneficial effects of the present invention are as follows: 1. The present invention is provided with a flip cover mechanism. When the staff opens the sealed door, the rotation of the sealed door will drive the connecting rope to move so that the pulling plate is pulled, so that the rotating shaft 2 rotates clockwise, and then the pressing plate also rotates and presses the fixed plate 1. Then the fixed plate 1 compresses the telescopic spring 1 to make the cover cover the cultured microorganisms, so as to prevent the pressure difference generated at the moment of opening the closed door from driving the outside air into the inner wall of the device to contaminate the microorganisms.

[0014] 2. The present invention sets a lighting mechanism. The servo motor drives the screw to rotate, and then drives the movable plate to move along the guide rod. During the movement, the ultraviolet lamp illuminates and disinfects the equipment and cultured microorganisms in the box shell. Since the ultraviolet lamp is mobile, the ultraviolet lamp will not continuously irradiate the cultured microorganisms, thereby preventing the microorganisms from being continuously irradiated and causing death. After that, the sealed door is opened regularly and the ventilation time of the incubator is set, thereby preventing the oxygen in the air from generating ozone under ultraviolet irradiation and producing an inhibitory effect on the cultured microorganisms.

[0015] 3. The present invention provides a lighting mechanism. When the movable plate moves, it drives the fixed block to move up and down, thereby making the gear and the rack come into contact, so that the rotating rod rotates, and drives the fan plate to rotate, thereby generating wind force, ensuring good air flow in the insulation layer, avoiding temperature differences in different areas of the box, affecting the consistency of the growth environment of the culture, and possibly causing abnormal growth of some cultures.

[0016] 4. The present invention sets an air intake mechanism, and the servo motor 2 will drive the rotating shaft 3 to rotate, thereby causing the fan blades to rotate slowly clockwise, thereby adsorbing air from above the filter plate into the processing frame. While the fan blades rotate, the push plate will drive the brush mechanism to work, and will drive the sliding plate to move upward along the support column for a distance, so that the brush will scratch the filter plate to avoid clogging of the filter plate due to long-term use. When the servo motor 2 stops working, the sliding plate will move downward and move to the bottom. The inertia generated thereafter will cause the drop plate to continue to move a distance and move the brush, so that the dust on the brush falls off, thereby achieving self-cleaning.

[0017] 5. The present invention sets an air outlet mechanism. During the hollow circulation flow of the device, some impurity molecules and dust molecules in the air are generated during the cultivation of microorganisms, which may block the air outlet gap, thereby causing the temperature in the incubator to continue to rise. As the temperature rises, the expansion fluid in the inner cavity expands and drives the movable plate 2 and the extrusion plate to move outward, so that the hollow protrusion squeezes out the dust and impurities on the air outlet gap and drops them onto the collecting plate 2.

The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses. Example 1, using Figure 1-Figure 15 A biochemical constant temperature incubator with a sterilization function according to one embodiment of the present invention is described as follows.

[0034] like Figure 1-Figure 3As shown, a biochemical constant temperature incubator with a sterilization function of the present invention comprises a box shell 1, a supporting foot 2 is symmetrically arranged at the bottom of the box shell 1, a sealing door 3 is rotatably connected to the front of the box shell 1, an air intake mechanism 5 is fixedly connected to the bottom of the outer surface of the box shell 1, an air outlet mechanism 6 is fixedly connected to the top of the outer surface of the box shell 1, an insulation layer 4 is fixedly connected to the inner wall of the box shell 1, a heating mechanism 7 is fixedly connected to the bottom of the insulation layer 4, and an adjustment mechanism 8 is fixedly connected to the top of the heating mechanism 7; When a biochemical constant temperature incubator with a sterilization function is working, the cultured microorganisms are first placed on the regulating mechanism 8, which controls and protects the cultured microorganisms. Then the air intake mechanism 5 evolves and inhales the outside air and heats it through the heating mechanism 7, and the air flows out of the device from the air outlet mechanism 6, thereby achieving constant temperature in the incubator.

[0035] like Figure 4 As shown, the adjustment mechanism 8 includes a side plate 81, which is symmetrically arranged on the top of the heating mechanism 7, and the outer surface of the side plate 81 is evenly provided with a magnetic block 82, and the side of the side plate 81 away from the magnetic block 82 is evenly provided with an insertion port 83, and the inner wall of the insertion port 83 is provided with a placement mechanism 86, the top of the side plate 81 is fixedly connected to a top plate 84, the bottom of the top plate 84 is fixedly connected to a rack 85, and the end of the top plate 84 away from the side plate 81 is fixedly connected to a side plate 2 89, the inner wall of the side plate 2 89 is slidably connected to a lighting mechanism 88, and the outer surface of the side plate 2 89 is rotatably connected to a flip cover mechanism 87; like Figure 5-Figure 7 As shown, the flip mechanism 87 includes a rotating shaft 871, the outer surface of which is fixedly connected to a cover plate 872, a fixing plate 873 is symmetrically provided at one end of the cover plate 872 away from the rotating shaft 871, a telescopic spring 874 is fixedly connected to the bottom of the fixing plate 873, a supporting plate 875 is fixedly connected to the bottom of the telescopic spring 874, the outer surface of the supporting plate 875 is fixedly connected to the opposite surface of the side plate 81, a fixing plate 876 is fixedly connected to one end of the side plate 81 close to the fixing plate 873, the outer surface of the fixing plate 876 is rotatably connected to a rotating shaft 877, a pressing plate 878 is fixedly connected to the outer surface of the rotating shaft 877, a pulling plate 879 is fixedly connected to the side of the rotating shaft 877 away from the pressing plate 878, and a connecting rope 8710 is fixedly connected to the outer surface of the pulling plate 879.

[0036] When the staff opens the sealed door, the rotation of the sealed door 3 will drive the connecting rope 8710 to move, thereby pulling the pulling plate 879, causing the rotating shaft 877 to rotate clockwise, and then the pressing plate 878 will also rotate and press the fixed plate 873. After that, the fixed plate 873 will compress the telescopic spring 874 and make the cover plate 872 cover the cultured microorganisms, preventing the pressure difference generated at the moment of opening the closed door from driving the outside air into the inner wall of the device and contaminating the microorganisms.

[0037] The two ends of the rotating shaft 1 871 are rotatably connected to the opposite surfaces of the side plate 2 89 , and the end of the connecting rope 8710 away from the pulling plate 879 is fixedly connected to the outer surface of the sealing door 3 .

[0038] like Figure 8 As shown, the lighting mechanism 88 includes a support block 881, the inner wall of the support block 881 is fixedly connected to a servo motor 882, the output end of the servo motor 882 is fixedly connected to a screw rod 883, the outer surface of the screw rod 883 is threadedly connected to a moving plate 884, the inner wall of the moving plate 884 is fixedly connected to an ultraviolet lamp 885, the end of the moving plate 884 away from the screw rod 883 is slidably connected to a guide rod 887, both ends of the guide rod 887 are fixedly connected to the outer surface of the support block 881, the two ends of the moving plate 884 are symmetrically provided with fixed blocks 886, the inner wall of the fixed block 886 is rotatably provided with a rotating rod 888, the outer surface of the rotating rod 888 is fixedly connected to a gear 889, and the end of the rotating rod 888 close to the gear 889 is fixedly connected to a fan plate 8810.

[0039] The servo motor 882 will drive the screw 883 to rotate, and then drive the movable plate 884 to move along the guide rod 887. During the movement, the ultraviolet lamp 885 will illuminate and disinfect the equipment and cultured microorganisms in the box shell 1. Since the ultraviolet lamp 885 is mobile, the ultraviolet lamp 885 will not continuously irradiate the cultured microorganisms, thereby preventing the microorganisms from being continuously irradiated and causing death. After that, the sealed door 3 is opened at a fixed time, and the ventilation time of the incubator is set to prevent the oxygen in the air from producing ozone under ultraviolet irradiation and having an inhibitory effect on the cultured microorganisms.

[0040] When the movable plate 884 moves, it will drive the fixed block 886 to move up and down, so that the gear 889 will come into contact with the rack 85, so that the rotating rod 888 will rotate, and drive the fan plate 8810 to rotate, thereby generating wind force, ensuring good air flow in the insulation layer 4, avoiding temperature differences in different areas of the box, affecting the consistency of the growth environment of the culture, and may cause abnormal growth of some cultures.

[0041] At the same time, the lighting mechanism 88 can also control the operation of the ultraviolet lamp 885, and put the yellow plastic shell wrapped with hydrogen peroxide into the device, and the ultraviolet lamp 885 irradiates the yellow plastic shell wrapped with hydrogen peroxide, so that the yellow plastic shell returns to its original color. (Added after communicating with Mr. Dai over the phone before) like Fig. 9 As shown, the placement mechanism 86 includes a support frame 861, the outer surface of the support frame 861 is wrapped with a reflective material 862, and the two ends of the support frame 861 are symmetrically provided with locking columns 863, and the outer surface of the locking column 863 is slidably connected to a magnetic block 864.

[0042] When installing the placement mechanism 86, when the support frame 861 is placed into the insertion port 83 of the side panel 1 81 and the side panel 2 89, the magnetic block 1 82 will attract the magnetic block 2 864, so that the magnetic block 2 864 enters the insertion port 83, thereby fixing the support frame 861 on the side panel 1 81 and the side panel 2 89 for easy placement.

[0043] The outer surface of the support block 881 is fixedly connected to the inner wall of the thermal insulation layer 4 , and the outer surface of the second magnetic block 864 is in contact with the inner wall of the insertion port 83 .

[0044] The specific workflow is as follows: When working, the servo motor 882 will drive the screw 883 to rotate, and then drive the moving plate 884 to move along the guide rod 887. During the movement, the ultraviolet lamp 885 will illuminate and disinfect the equipment and cultured microorganisms in the box shell 1. Since the ultraviolet lamp 885 is moving, the ultraviolet lamp 885 will not continuously irradiate the cultured microorganisms, thereby preventing the microorganisms from being continuously irradiated and causing death. When the moving plate 884 moves, it will drive the fixed block 886 to move up and down, thereby causing the gear 889 to come into contact with the rack 85, thereby causing the rotating rod 888 to rotate, and driving the fan plate 8810 to rotate, thereby generating wind power to ensure heat preservation. The good air flow in layer 4 avoids the temperature difference in different areas of the box, which affects the consistency of the growth environment of the culture and may cause abnormal growth of some cultures. When the staff needs to open the sealed door 3, the rotation of the sealed door 3 will drive the connecting rope 8710 to move, so that the pulling plate 879 is pulled, so that the rotating shaft 877 rotates clockwise, and then the pressing plate 878 also rotates and presses the fixed plate 873. After that, the fixed plate 873 will compress the telescopic spring 874 and make the cover plate 872 cover the cultured microorganisms, so as to prevent the pressure difference generated at the moment of opening the closed door from driving the outside air into the inner wall of the device to contaminate the microorganisms.

[0045] Example 2, using Figure 1-Figure 15 A biochemical constant temperature incubator with a sterilization function according to one embodiment of the present invention is described as follows.

[0046] like Figure 10-11As shown, a biochemical constant temperature incubator with a sterilization function of the present invention is based on the first embodiment, and the heating mechanism 7 includes a bottom box 71, the surface of the bottom box 71 is provided with an air outlet 74, the bottom of the bottom box 71 is fixedly connected to the bottom of the insulation layer 4, the inner wall of the bottom box 71 is slidably connected with a collecting plate 72, the top of the bottom box 71 is fixedly connected with a support column 73, the top of the support column 73 is fixedly connected with a layer rack 75, the top of the layer rack 75 is fixedly connected to the bottom of the side panel 81, the outer surface of the layer rack 75 is fixedly connected with a fan 76, the inner wall of the bottom box 71 is symmetrically provided with heating devices 77, the opposite surface of the heating device 77 is fixedly connected with a heating column 78, the top of the bottom box 71 is fixedly connected with a protruding block 79, and the outer surface of the protruding block 79 is fixedly connected with an air inlet pipe 710.

[0047] After the air enters the bottom box 71 through the air inlet pipe 710, the heating device 77 will heat the air through the heating column 78, and the air will then enter the space of the adjustment mechanism 8 through the air outlet 74. Since the density of hot air is smaller than that of cold air, the heated air will move upward.

[0048] like Figure 12-13 As shown, the air intake mechanism 5 includes a support plate 51, a processing frame 52 is fixedly connected to the bottom of the support plate 51, a servo motor 54 is fixedly connected to the outer surface of the processing frame 52, a filter plate 53 is fixedly connected to the side of the processing frame 52 away from the box shell 1, a brushing mechanism 59 is fixedly connected to the inner wall of the filter plate 53, a rotating shaft 55 is fixedly connected to the output end of the servo motor 54, a fan blade 56 is fixedly connected to the outer surface of the rotating shaft 55, a push plate 510 is fixedly connected to both sides of the fan blade 56, a support column 57 is fixedly connected to the bottom of the filter plate 53, and a scratch plate 58 is fixedly connected to the side of the support column 57 away from the filter plate 53.

[0049] Servo motor 2 54 drives shaft 3 55 to rotate, thereby causing fan blades 56 to rotate clockwise more slowly, thereby adsorbing air from above the filter plate 53 into the processing frame 52. While fan blades 56 rotate, push plate 510 drives brush mechanism 59 to work.

[0050] like Fig.14 As shown, the brushing mechanism 59 includes a support column three 591, the outer surface of the support column three 591 is slidably connected to a sliding plate 592, the outer surface of the sliding plate 592 is fixedly connected to a brush 593, the top of the sliding plate 592 is fixedly connected to a support plate three 594, the top of the support plate three 594 is fixedly connected to a telescopic spring two 595, and the bottom of the telescopic spring two 595 is fixedly connected to a drop plate 596.

[0051] The pushing plate 510 will collide with the sliding plate 592, thereby driving the sliding plate 592 to move upward along the support column for a distance, so that the brush 593 will scratch the filter plate 53, thereby preventing the filter plate 53 from being blocked due to long-term use. When the servo motor 2 54 stops working, the sliding plate 592 will move downward and move to the bottom. The inertia generated thereafter will cause the drop plate 596 to continue to move for a distance and move the brush 593, so that the dust on the brush 593 falls off, thereby achieving self-cleaning.

[0052] The top of the second support plate 51 is fixedly connected to the outer surface of the box shell 1, and the two ends of the third support column 591 are fixedly connected to the inner wall of the filter plate 53.

[0053] like Fig.15 As shown, the air outlet mechanism 6 includes a top box 61, the outer surface of the top box 61 is fixedly connected to the top of the thermal insulation layer 4, the inner wall of the top box 61 is provided with an inner cavity 62, the outer surface of the inner cavity 62 is slidably connected to a movable plate 2 68, the outer surface of the movable plate 2 68 is fixedly connected to an extrusion plate 63, the side of the extrusion plate 63 away from the movable plate 2 68 is fixedly connected to a hollow protrusion 64, the outer surface of the box shell 1 is fixedly connected to an isolation plate 65, the bottom of the isolation plate 65 is fixedly connected to a bottom column 66, and the outer surface of the bottom column 66 is slidably connected to a collecting plate 2 67.

[0054] During the hollow circulation flow of the device, some impurity molecules and dust molecules in the air will be generated during the cultivation of microorganisms, which may block the air outlet gap, causing the temperature in the incubator to continue to rise. As the temperature rises, the expansion fluid in the inner cavity 62 will expand and drive the movable plate 2 68 and the extrusion plate 63 to move outward, so that the hollow protrusion 64 will squeeze out the dust and impurities on the air outlet gap and drop them onto the collection plate 2 67.

[0055] The specific workflow is as follows: When working, the servo motor 2 54 will drive the rotating shaft 3 55 to rotate, thereby causing the fan blade 56 to rotate clockwise at a slower speed, thereby adsorbing air from the top of the filter plate 53 into the processing frame 52. While the fan blade 56 is rotating, the push plate 510 will drive the brush mechanism 59 to work, and will drive the sliding plate 592 to move upward along the support column for a distance, so that the brush 593 will scratch the filter plate 53 to avoid clogging caused by long-term use of the filter plate 53. When the servo motor 2 54 stops working, the sliding plate 592 will move downward and move to the bottom, and the inertia generated thereafter will cause the drop plate 596 to continue to move a distance and to flick the brush 593, so that the brush 5 The dust on 93 falls off, and then the air enters the bottom box 71 through the air inlet pipe 710. The heating device 77 heats the air through the heating column 78, and the air enters the space of the regulating mechanism 8 through the air outlet 74. Since the density of hot air is smaller than that of cold air, the heated air will move upward. During the process of culturing microorganisms, some impurity molecules and dust molecules in the air may block the air outlet gap, thereby causing the temperature in the incubator to continue to rise. As the temperature rises, the expansion fluid in the inner cavity 62 will expand and drive the movable plate 2 68 and the extrusion plate 63 to move outward, so that the hollow protrusion 64 squeezes out the dust and impurities on the air outlet gap and drops them onto the collecting plate 2 67.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
