Description

Technical Field

[0001] The present invention relates to the technical field of mold culture, and particularly to a device capable of uniformly adjusting the microbial culture environment. Background Art

[0002] Mold research is widely applied in fields such as biology, medicine, food science, and environmental science. In the fields of microbiology and biology, by culturing and observing molds, biological characteristics such as their growth characteristics, reproduction methods, and metabolic pathways can be deeply understood, providing basic data for subsequent in-depth research. A mold culture device is a device used to culture molds in a laboratory environment. It usually has a constant temperature condition to simulate the natural environment required for mold growth. In traditional mold culture work, petri dishes are used to grow molds, and the petri dishes are stored in a mold incubator to keep the petri dishes in a constant temperature environment for mold culture.

[0003] In the prior art, the mold culture device has a built-in temperature adjustment function, which usually consists of a heating device and a temperature detection device. The heating device heats the internal space of the culture device to maintain the petri dish in a constant temperature environment. However, in traditional mold culture devices, the position of the petri dish in the culture device is fixed, resulting in the temperature of the petri dish closer to the heating device being higher than that of the petri dish farther from the heating device, leading to a certain deviation in the growth environment of molds in different petri dishes; the traditional culture device has a cabinet structure. When taking out or putting in the petri dish or observing the growth status of the mold, opening the door of the culture device will cause heat loss inside the culture device, resulting in fluctuations in the mold culture environment, which is not conducive to the growth of molds and will also increase the energy consumption of the device.

[0004] The present invention discloses a device capable of uniformly adjusting the microbial culture environment to solve the problems in the prior art that the mold culture device has a built-in temperature adjustment function, which usually consists of a heating device and a temperature detection device. The heating device heats the internal space of the culture device to maintain the petri dish in a constant temperature environment. However, in traditional mold culture devices, the position of the petri dish in the culture device is fixed, resulting in the temperature of the petri dish closer to the heating device being higher than that of the petri dish farther from the heating device, leading to a certain deviation in the growth environment of molds in different petri dishes; the traditional culture device has a cabinet structure. When taking out or putting in the petri dish or observing the growth status of the mold, opening the door of the culture device will cause heat loss inside the culture device, resulting in fluctuations in the mold culture environment, which is not conducive to the growth of molds and will also increase the energy consumption of the device.

[0005] In the first aspect of the present disclosure, a device capable of uniformly adjusting the microbial culture environment is provided, specifically including: a culture box base, above which a circular mold culture box is installed. The center of the upper surface of the culture box base is fixedly connected with a turntable driving member, and the upper end of the rotating shaft of the turntable driving member is fixedly connected with a total turntable in the form of a disc structure. The total turntable is coaxial with the mold culture box. The total turntable is rotatably connected with six guiding rotating shafts through bearings. A rotating shaft guiding port is formed through the center of the guiding rotating shaft, and a turntable supporting rod is slidably connected in the rotating shaft guiding port. The upper end of the turntable supporting rod is fixedly connected with a sub-turntable. The top inside the mold culture box is connected with a temperature regulating fan through a bracket. The upper surface of the culture box base is fixedly connected with a supporting motor. The rotating shaft of the supporting motor is fixedly connected with a supporting driving screw through a coupling. A lifting bracket is installed on the supporting driving screw. The upper surface of the culture box base is welded with an inner supporting cylinder, which is a cylindrical structure. The inner supporting cylinder is coaxial with the culture box base and the mold culture box. The upper edge of the outer surface of the inner supporting cylinder is fixedly connected with a cylinder gear ring. The lower end of the guiding rotating shaft is connected with a rotating gear through interference fit, and the rotating gear is meshed with the cylinder gear ring.

[0006] Further, a storage groove is formed on the upper surface of the culture box base, and a guiding groove is formed through the left side wall of the inner supporting cylinder.

[0007] Further, the lifting bracket is slidably connected in the guiding groove. A bracket screw hole is formed longitudinally through the right end of the lifting bracket, and the bracket screw hole is spirally connected with the supporting driving screw.

[0008] Further, the left end supporting rod of the lifting bracket is located inside the storage groove, and a "V" - shaped groove is formed on the upper surface of the left end supporting rod of the lifting bracket.

[0009] Further, a culture dish access opening is provided at the top edge position of the mold culture box, and an access opening cover plate is covered above the culture dish access opening.

[0010] Further, six circular - groove - structured turntable grooves are formed on the total turntable, and the six turntable grooves are radially distributed on the upper surface of the total turntable with the axis of the total turntable as the center.

[0011] Further, four inner sliding grooves of the rotating shaft are formed on the inner wall of the rotating shaft guiding port, and four protruding bars of the supporting rod are convexly provided on the outer wall of the turntable supporting rod. The protruding bars of the supporting rod are slidably connected with the inner sliding grooves of the rotating shaft.

[0012] Further, the six guiding rotating shafts are respectively rotatably connected to the centers of the six turntable grooves.

[0013] Further, a universal wheel is installed at the lower end of the turntable supporting rod, and a linkage convex plate is welded on the upper surface of the culture box base. The linkage convex plate is in a circular - arc structure, and the center of the circle of the linkage convex plate is located in the axis of the culture box base.

[0014] Further, the upper edge of the linkage convex plate is in an arc structure, and the universal wheel is rollingly connected to the upper edge of the linkage convex plate.

[0015] The present invention provides a device capable of uniformly adjusting the microbial culture environment, having the following beneficial effects: In the mold culture device of the present invention, a main turntable and sub-turntables are built in. Six groups of mold culture dishes are placed through six sub-turntables. During the operation of the mold culture device, air at a set temperature is conveyed to the periphery through the side of the temperature-adjusting fan, and the temperature of the culture dishes is adjusted through the air, so that the culture dishes are in a constant temperature state. The sub-turntables and the culture dishes are distributed around the periphery of the temperature-adjusting fan, and the distances between different culture dishes and the temperature-adjusting fan are the same, effectively avoiding the situation that the culture dishes at different positions are unevenly heated due to different distances from the temperature-adjusting equipment; At the same time, the main turntable is driven by a turntable driving member to rotate slowly and uniformly. While the main turntable rotates, six guiding rotating shafts are driven to rotate accordingly. The rotary gear and the support cylinder tooth ring form a gear transmission to drive its own rotation. While the guiding rotating shafts rotate, the turntable support rods and the sub-turntables are driven to rotate, so that the culture dishes above the sub-turntables continuously switch the direction facing the temperature-adjusting fan, enabling multiple directions of the culture dishes to be adjusted by the temperature-adjusting fan, improving the temperature-adjusting uniformity, and avoiding the phenomenon of uneven heating caused by the culture dishes fixedly facing the temperature-adjusting fan; Moreover, as the main turntable rotates, the universal wheels at the lower ends of some sub-turntables enter the linkage convex plate and adjust their heights along with the arc-shaped flange of the linkage convex plate, causing the culture dishes to slowly rise and fall inside the mold incubator, and enabling the bottom and top directions of the culture dishes to alternately contact the air blown out by the temperature-adjusting fan, further improving the temperature-adjusting uniformity of the culture dishes.

[0016] In addition, a single-group control lifting structure for the culture dish is built in the mold incubator. The jacking motor drives the jacking driving screw to rotate, and the screw drive between the jacking driving screw and the bracket screw hole pushes the lifting bracket to rise, pushing the turntable support rod and the sub-turntable at this position upward, so that the culture dish enters the culture dish access opening. The lower end of the culture dish access opening is sealed by the sub-turntable, and then the access opening cover plate is opened to take and observe the culture dish. During the process of taking and observing the culture dish, the bottom of the culture dish access opening is in a closed state, and external air will not enter the inside of the mold incubator, which will not affect the internal temperature of the culture device, and avoid the situation that the heat loss causes fluctuations in the mold culture environment and increases the energy consumption of the equipment.

At the top edge position of the mold culture box 2, a culture dish access opening 201 is provided, and an access opening cover plate 202 is covered above the culture dish access opening 201; by driving the supporting driving screw rod 9 to rotate through the supporting motor 8, the screw transmission between the supporting driving screw rod 9 and the bracket screw hole 1001 pushes the lifting bracket 10 to rise, pushing the turntable supporting rod 601 and the sub-turntable 6 at this position upward, so that the culture dish enters the culture dish access opening 201. The lower end of the culture dish access opening 201 is sealed by the sub-turntable 6. Then, the access opening cover plate 202 is opened to take and observe the culture dish. During the process of taking and observing the culture dish, the bottom of the culture dish access opening 201 is in a closed state, which will not cause external air to enter the inside of the mold culture box 2 and affect the internal temperature of the culture device, avoiding the situation that the culture environment of the mold fluctuates due to heat loss and increasing the energy consumption of the equipment.

The lower end of the guiding rotation shaft 5 is connected with a rotating gear 503 by interference fit, and the rotating gear 503 is meshed with the support cylinder gear ring 103.

[0026] In the embodiment of the present disclosure, six turntable grooves 401 with a circular groove structure are formed on the total turntable 4. The six turntable grooves 401 are radially distributed on the upper surface of the total turntable 4 with the axis of the total turntable 4 as the center. The total turntable 4 is driven to rotate by a turntable driving member 3 to adjust the position of the culture dish above the total turntable 4, so that the universal wheels 603 at the bottom of the sub-turntable 6 are docked with the lifting bracket 10, and the sub-turntable 6 and the culture dish at this position are lifted by the lifting bracket 10.

[0027] In the embodiment of the present disclosure, four inner sliding grooves 502 of the rotation shaft are formed on the inner wall of the rotation shaft guide opening 501. Four protruding bars 602 are convexly provided on the outer wall of the turntable support rod 601. The protruding bars 602 are slidably connected to the inner sliding grooves 502 of the rotation shaft to play a guiding role, and the torque is transmitted through the cooperation of the inner sliding grooves 502 of the rotation shaft and the protruding bars 602, so that the sub-turntable 6 rotates following the guiding rotation shaft 5 to adjust the orientation. The six guiding rotation shafts 5 are respectively rotatably connected to the centers of the six turntable grooves 401. The total turntable 4 is driven to rotate slowly and uniformly by the turntable driving member 3. While the total turntable 4 rotates, it drives the six guiding rotation shafts 5 to rotate accordingly. The rotating gear 503 and the support cylinder gear ring 103 form a gear transmission to drive its own rotation. While the guiding rotation shaft 5 rotates, it drives the turntable support rod 601 and the sub-turntable 6 to rotate, so that the culture dish above the sub-turntable 6 continuously switches the orientation towards the temperature regulating fan 7, so that multiple directions of the culture dish can be regulated by the temperature regulating fan 7, improving the temperature regulation uniformity and avoiding the phenomenon of uneven heating caused by the culture dish being fixed in the direction towards the temperature regulating fan 7.

[0028] In the second embodiment, on the basis of the first embodiment, a linkage convex plate 105 is welded on the upper surface of the incubator base 1. The linkage convex plate 105 is of an arc-shaped structure, and the center of the linkage convex plate 105 is located in the axis of the incubator base 1; the upper edge of the linkage convex plate 105 is of an arc-shaped structure, and the universal wheels 603 are rollingly connected to the upper edge of the linkage convex plate 105; as the total turntable 4 rotates, the universal wheels 603 at the lower ends of some sub-turntables 6 enter the linkage convex plate 105 and adjust the height along with the arc-shaped flange of the linkage convex plate 105, so that the culture dish slowly undulates inside the mold incubator 2, and the bottom and top directions of the culture dish alternately contact the air blown by the temperature regulating fan 7, improving the temperature regulation efficiency of the culture dish.

[0029] Working principle of this embodiment: First, when placing the culture dish into the mold culture device, control the rotation of the turntable driving member 3 to adjust the position of the sub-turntable 6, transfer the idle sub-turntable 6 above the left end rod of the lifting bracket 10, so that the universal wheel 603 is above the left end rod of the lifting bracket 10. Start the jacking motor 8, and lift the lifting bracket 10 through the screw drive of the jacking drive screw 9 and the bracket screw hole 1001, and lift the sub-turntable 6 upward, so that the sub-turntable 6 reaches the lower end of the culture dish access port 201. Seal the culture dish and place it stably at the center of the sub-turntable 6, and fasten the access port cover plate 202. Reverse-start the jacking motor 8 to synchronously lower the lifting bracket 10 and the sub-turntable 6 into the mold incubator 2. During the mold culture process, turn on the temperature-adjusting fan 7 and the turntable driving member 3. The air inlet of the temperature-adjusting fan 7 is located at the upper end and the lower end, and the air outlet is located on the side. During the operation of the temperature-adjusting fan 7, air is inhaled through its upper and lower air inlets, and after the air is temperature-adjusted, it is conveyed to the surrounding through its side air outlet to warm the culture dishes above the surrounding sub-turntables 6. Drive the main turntable 4 to rotate through the turntable driving member 3. While the main turntable 4 rotates, drive the six guiding rotating shafts 5 to rotate accordingly. The rotary gear 503 and the support cylinder tooth ring 103 form a gear drive to drive its own rotation. While the guiding rotating shaft 5 rotates, drive the turntable support rod 601 and the sub-turntable 6 to rotate, so that the culture dishes above the sub-turntable 6 continuously switch the direction towards the temperature-adjusting fan 7, so that multiple directions of the culture dishes can be adjusted by the temperature-adjusting fan 7. At the same time, the universal wheels 603 at the lower ends of some sub-turntables 6 enter the linkage convex plate 105 and adjust the height along with the arc-shaped flange of the linkage convex plate 105, so that the culture dishes slowly undulate inside the mold incubator 2, so that the bottom and top directions of the culture dishes alternately contact the air blown out by the temperature-adjusting fan 7, so that the upper, lower and side surfaces of the culture dishes are all in contact with the constant-temperature air emitted by the temperature-adjusting fan 7 to achieve more uniform and rapid temperature adjustment.
