Description

Technical Field

[0001] The present invention belongs to the technical field of probiotic cultivation, and particularly relates to a probiotic cultivation device and method. Background Art

[0002] Probiotics are a type of microorganisms beneficial to the host. They can help maintain a healthy digestive system in the human intestine and contribute to enhancing immune function.

[0003] When cultivating probiotics, first, a suitable strain needs to be selected, and then its culture medium needs to be determined. Since the growth conditions of probiotics are harsh, they need to be placed in a dedicated incubator that can maintain a constant growth environment, such as temperature, humidity, etc.

[0004] However, in the prior art, there are multiple positions for placing culture dishes in the existing incubator. In actual use, the operator needs to first open the door of the incubator and then place the culture dish at the designated position. This storage method is actually rather cumbersome because the operator needs to operate manually, pay attention to the placement position, and at the same time, the hand needs to reach into the incubator and the door is in an open state, which easily causes a serious imbalance in the environmental conditions constructed inside the incubator. Therefore, a probiotic cultivation device and method are proposed to solve the above problems. Summary of the Invention

[0005] The purpose of the embodiments of the present invention is to provide a probiotic cultivation device and method, aiming to solve the problems mentioned in the above background art.

[0006] The embodiments of the present invention are implemented as follows. A probiotic cultivation device includes a box body, and a cover plate that can be opened and closed is rotatably arranged on the top of the box body. It further includes:

[0007] A loading component, the loading component is located inside the box body. The loading component includes a disk body fixedly connected horizontally inside the box body. An inner ring body and an outer ring body are arranged at intervals on the disk body. An annular slideway is formed between the inner ring body and the outer ring body. A plurality of loading disks for loading culture dishes are arranged in the annular slideway. A fitting slot is formed on the disk body, and a plate body is slidably inserted into the fitting slot. A switch door plate is arranged on the box body, and the switch door plate is fixedly connected to one end of the plate body. An inner arc-shaped strip and an outer arc-shaped strip are fixedly connected to the plate body. The inner arc-shaped strip and the inner ring body form a complete circular structure, and the outer arc-shaped strip and the outer ring body form a complete circular structure;

[0008] A driving component, a cover shell is fixedly connected to the bottom of the disk body, and the driving component is located inside the cover shell. The driving component is used to drive the plate body to move along the radial direction of the disk body, and the driving component is also used to drive a single loading disk to rotate in the annular slideway, so that the overall loading disks are rotated in position.

[0009] Preferably, the transverse span of the outer arc-shaped strip is greater than the diameter of the bearing disc, and the transverse span of the inner arc-shaped strip is less than the diameter of the bearing disc. Annular limiting grooves communicating with each other are formed in the disc body and the plate body. When the plate body and the disc body are in a mating state, the annular limiting grooves are located in the annular slideway. A positioning ring is fixedly connected to the bottom of the bearing disc, and the positioning ring is located in the annular limiting groove. An arc-shaped through groove with a set arc length is formed at the bottom of the annular limiting groove. The driving assembly is used to drive the bearing disc to rotate through the positioning ring located in the arc-shaped through groove.

[0010] Preferably, the driving assembly includes a rotary driving member fixedly connected to the top of the disc body. The output end of the rotary driving member is a driving screw rod arranged along the length direction of the plate body. A connecting frame fixedly connected to the plate body is arranged in a matching manner on the driving screw rod. When the rotary driving member drives the driving screw rod to rotate, the plate body is driven to move transversely through the connecting frame. A power storage assembly capable of driving the positioning ring in the arc-shaped through groove to move from one end to the other end is further arranged on the top of the disc body, and the central angle corresponding to the displacement of the positioning ring is equal to the central angle corresponding to the centers of two adjacent receiving discs. Limiting strips are fixedly connected to both ends of the inner arc-shaped strip and are arranged towards the center of the disc body. When the bearing disc on the plate body is moved out of the plate body, the limiting strips are used to fix the bearing discs on both sides of the bearing disc, and at this time, the power storage assembly does not drive the positioning ring to move in the arc-shaped through groove. When the bearing disc on the plate body is reset, the power storage assembly drives the positioning ring to move in the arc-shaped through groove, so that the bearing discs on the plate body are rotated.

[0011] Preferably, the power storage assembly includes a plurality of cylinders fixedly connected to the bottom of the disc body. The cylinder rods of the cylinders are fixedly connected to the connecting frame. The arrangement direction of the cylinders is the same as the direction of the driving screw rod. When the plate body is moved out of the disc body, the cylinders are in a compressed state. The input end of the cylinder is an air inlet pipe provided with a first one-way valve, and the output end of the cylinder is an air outlet pipe provided with a second one-way valve. The other end of the air outlet pipe is connected to a power conversion member. The output end of the power conversion member is a rod body capable of moving along the length direction of the plate body. An installation block is slidably sleeved on the rod body. An elastic resetting member for adjusting the position of the installation block is arranged on the rod body. A pin shaft matched with the positioning ring is rotatably arranged on one side of the installation block facing the positioning ring. When the pin shaft pushes the positioning ring to move towards the plate body side, the rotation of the pin shaft is restricted. When the pin shaft moves towards the side away from the plate body, the rotation of the pin shaft is not restricted, so that the pin shaft is disengaged from the positioning ring.

[0012] Preferably, the power conversion member includes a strip-shaped box body fixedly connected to the bottom of the disk body. An elastic air bag connected to the air outlet pipe is arranged in the strip-shaped box body. The other end of the elastic air bag is provided with an exhaust pipe, and the exhaust pipe is fixedly connected to a slider slidably arranged in the strip-shaped box body. A control valve is fixedly arranged at the end of the exhaust pipe. A chute is arranged on one side of the strip-shaped box body, and the rod body is connected to the slider through the chute. The control valve is used to empty the air in the elastic air bag.

[0013] Preferably, a rectangular opening is formed in the cover shell, and a net plate is fixedly connected in the rectangular opening.

[0014] Preferably, a display controller is fixedly arranged on the cover plate, and a switch handle is arranged on one side of the cover plate far from the rotation connection of the cover plate and the box body.

[0015] Another object of the present invention is to provide a probiotic cultivation method, and the probiotic cultivation method includes the following steps:

[0016] Step 1: When it is necessary to place the culture dish for cultivating probiotics, the rotation driving member is controlled to work through the display controller, the driving screw rotates to drive the plate body to move horizontally, so that the switch door plate opens, and the plate body carries a carrier plate out of the box body;

[0017] Step 2: After the culture dish is placed on the carrier plate, the driving screw rotates in the reverse direction, so that the plate body retracts into the box body and resets on the disk body. At the same time, the switch door plate resets and closes;

[0018] Step 3: Since the elastic air bag stores gas, when the plate body resets, the limiting strip resets, and the annular slideway on the disk body is formed. At this time, the elastic air bag elongates, and the positioning ring can be driven to move through the pin shaft, and the carrier plate corresponding to the positioning ring rotates, so that the original carrier plate on the plate body is replaced;

[0019] Step 4: After the carrier plate is replaced, the control valve is opened, so that the gas in the elastic air bag is discharged, and the pin shaft resets under the material characteristics of the elastic air bag itself. Since the rotation of the pin shaft is not restricted, the pin shaft disengages from the original positioning ring, and after reaching the initial state, the pin shaft is inserted into another positioning ring.

[0020] The beneficial effects of a probiotic cultivation device and method provided by an embodiment of the present invention are:

[0021] The device limits multiple carrier plates through an annular slideway provided on the disk body, and this annular structure is also beneficial to the rotation of the carrier plates. When it is necessary to place a culture dish, the driving component can be used to make the plate body carry a carrier plate and extend out. The operator only needs to place the culture dish on the extended carrier plate. After the main body carries the carrier plate and resets, the driving component can also control the rotation of the carrier plate in the annular slideway, so that the carrier plate in the empty state is located on the plate body, which is beneficial to the storage of the culture dish next time. In summary, when the device places the culture dish, it can make the internal space interact less with the outside world, so that less of the environmental conditions suitable for the growth of probiotics created by the box body are lost, and the device makes it more convenient and faster for the operator to place the culture dish.

[0031] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0033] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 shown, an embodiment of the present invention provides a probiotic cultivation device, including a box body 1, a rotatably arranged cover plate 2 that can be opened and closed is arranged at the top of the box body 1, and further includes:

[0034] A carrier assembly, the carrier assembly is located inside the box body 1, the carrier assembly includes a disk body 3 fixedly connected horizontally inside the box body 1, an inner ring body 4 and an outer ring body 5 are arranged at intervals on the disk body 3, an annular slideway 6 is formed between the inner ring body 4 and the outer ring body 5, a plurality of carrier disks 7 for carrying culture dishes are arranged in the annular slideway 6 in a row, a fitting slot is formed on the disk body 3, a plate body 8 is slidably inserted into the fitting slot, a switch door panel 9 is arranged on the box body 1, the switch door panel 9 is fixedly connected to one end of the plate body 8, an inner arc strip 10 and an outer arc strip 11 are fixedly connected to the plate body 8, the inner arc strip 10 and the inner ring body 4 form a complete circular structure, and the outer arc strip 11 and the outer ring body 5 form a complete circular structure;

[0035] A driving assembly, the bottom of the disk body 3 is fixedly connected with a housing 12, the driving assembly is located inside the housing 12, the driving assembly is used to drive the plate body 8 to move along the radial direction of the disk body 3, and the driving assembly is further used to drive a single carrier disk 7 to rotate in the annular slideway 6, so that the overall carrier disks 7 are rotated in position.

[0036] In an embodiment of the present invention, the device limits a plurality of carrier plates 7 through an annular slideway 6 provided on a disk body 3, and this annular structure is also beneficial to the rotation of the carrier plates 7. When a culture dish needs to be placed, the driving component can be used to make the plate body 8 carry a carrier plate 7 to extend out. The operator only needs to place the culture dish on the extended carrier plate 7. After the main body carries the carrier plate 7 back to its original position, the driving component can also control the carrier plate 7 to rotate within the annular slideway 6, so that the carrier plate 7 in the empty state is located on the plate body 8, which is beneficial to the storage of the culture dish next time. In summary, when the device places the culture dish, it can make the internal space interact less with the outside world, so that the environmental conditions suitable for the growth of probiotics created by the box body 1 are lost less, and the device makes it more convenient and faster for the operator to place the culture dish.

[0037] In an example of the present invention, as Figure 1 shown, a display controller 36 is fixedly arranged on the cover plate 2. On one side of the cover plate 2 away from the rotation connection between the cover plate 2 and the box body 1, a switch handle 37 is arranged. The presence of the switch handle 37 can make the cover plate 2 fully opened, so that the internal carrier plate 7 is completely exposed. When a large number of culture dishes need to be placed, this method can be adopted. The device does not abandon the traditional opening and closing method of the incubator, and the operator can choose according to actual needs. In addition, an adjustment integrator 38 for adjusting the internal environment of the box body 1 is also arranged on the cover plate 2. The temperature, humidity, ventilation, etc. inside the box body 1 can be controlled through the adjustment integrator 38. This kind of equipment is a conventional method in existing incubators, so it will not be described in detail here.

[0038] As Figure 6 、 Figure 7 shown, as a preferred embodiment of the present invention, the lateral span of the outer arc-shaped strip 11 is greater than the diameter of the carrier plate 7, and the lateral span of the inner arc-shaped strip 10 is less than the diameter of the carrier plate 7. Annular limiting grooves 13 communicating with each other are formed on the disk body 3 and the plate body 8. When the plate body 8 and the disk body 3 are in a matching state, the annular limiting grooves 13 are located inside the annular slideway 6. A positioning ring 14 is fixedly connected to the bottom of the carrier plate 7, and the positioning ring 14 is located inside the annular limiting groove 13. An arc-shaped through groove 15 with a set arc length is formed at the bottom of the annular limiting groove 13. The driving component is used to drive the carrier plate 7 to rotate through the positioning ring 14 located inside the arc-shaped through groove 15.

[0039] In a situation of this embodiment, as Figure 5As shown, the driving assembly includes a rotary driving member 16 fixedly connected to the top of the disk body 3. The output end of the rotary driving member 16 is a driving screw 17 arranged along the length direction of the plate body 8. A connecting frame 18 fixedly connected to the plate body 8 is arranged in a matching manner on the driving screw 17. When the rotary driving member 16 drives the driving screw 17 to rotate, the plate body 8 is driven to move laterally through the connecting frame 18. A power storage assembly capable of driving the positioning ring 14 in the arc-shaped through groove 15 to move from one end to the other end is further arranged on the top of the disk body 3, and the central angle corresponding to the displacement of the positioning ring 14 is equal to the central angle corresponding to the centers of two adjacent receiving disks. The limitation of the movement of the positioning ring 14 also limits the size of the arc-shaped through groove 15, ensuring that when the bearing disks 7 are rotated, only the position of one bearing disk 7 is pushed to move, so as to ensure that each time a new bearing disk 7 is rotated onto the plate body 8. Both ends of the inner arc-shaped strip 10 are fixedly connected with limiting strips 19 arranged towards the center of the disk body 3. When the bearing disk 7 on the plate body 8 is removed from the plate body 8, the limiting strips 19 are used to fix the bearing disks 7 on both sides of the bearing disk 7 (since the plate body 8 is removed from the disk body 3, at this time the limiting strips 19 are also removed, and at this time the two bearing disks 7 on both sides of the bearing disk 7 on the plate body 8 cannot be displaced under the action of the limiting strips 19), and at this time the power storage assembly does not drive the positioning ring 14 to move in the arc-shaped through groove 15. When the bearing disk 7 on the plate body 8 is reset, the power storage assembly drives the positioning ring 14 to move in the arc-shaped through groove 15, so that the bearing disks 7 on the plate body 8 are rotated. In this embodiment, the movement of the plate body 8 and the rotation of the bearing disks 7 are combined, and no additional driving force needs to be added to control the rotation of the bearing disks 7.

[0040] As Figure 5 , Figure 7 and Figure 8As shown, as a preferred embodiment of the present invention, the power storage assembly includes a plurality of cylinders 20 fixedly connected to the bottom of the disk body 3. The cylinder rods of the cylinders 20 are fixedly connected to the connecting frame 18. The installation direction of the cylinders 20 is the same as that of the driving screw 17. When the plate body 8 is moved out of the disk body 3, the cylinders 20 are in a compressed state. The input end of the cylinder 20 is an air inlet pipe 22 provided with a first one-way valve 23. The output end of the cylinder 20 is an air outlet pipe 24 provided with a second one-way valve 25. The other end of the air outlet pipe 24 is connected to the power conversion member. The output end of the power conversion member is a rod body 26 that can move along the length direction of the plate body 8. An installation block 27 is slidably sleeved on the rod body 26. An elastic reset member 28 for adjusting the position of the installation block 27 is provided on the rod body 26. A pin shaft 29 that cooperates with the positioning ring 14 is rotatably provided on one side of the installation block 27 facing the positioning ring 14. When the pin shaft 29 pushes the positioning ring 14 to move towards the plate body 8 side, the rotation of the pin shaft 29 is restricted. When the pin shaft 29 moves towards the side away from the plate body 8, the rotation of the pin shaft 29 is not restricted, so that the pin shaft 29 is disengaged from the positioning ring 14.

[0041] In one case of this embodiment, the power conversion member includes a strip-shaped box body 30 fixedly connected to the bottom of the disk body 3. An elastic air bag 31 connected to the air outlet pipe 24 is arranged in the strip-shaped box body 30. The other end of the elastic air bag 31 is provided with an exhaust pipe 32. The exhaust pipe 32 is fixedly connected to a slider 33 slidably arranged in the strip-shaped box body 30. A control valve 34 is fixedly arranged at the end of the exhaust pipe 32. A chute 21 is opened on one side of the strip-shaped box body 30. The rod body 26 is connected to the slider 33 through the chute 21. The control valve 34 is used to empty the air in the elastic air bag 31. After adopting the above structure, when the plate body 8 drives the bearing plate 7 to move out, the connecting frame 18 will drive the cylinder rod to move, so as to send the air in the cylinder 20 into the elastic air bag 31 through the air outlet pipe 24. However, at this time, the bearing plate 7 is restricted by the limiting strip 19 and cannot rotate (the annular slideway 6 is incomplete). When the culture dish is placed on the bearing plate 7, the rotation driving member 16 will control the driving screw 17 to rotate in the reverse direction, so that the plate body 8 is reset. At this time, the limiting strip 19 is also reset, and the annular slideway 6 also presents a complete circular ring shape. At this time, the elastic air bag 31 will cause the slider 33 to move. At this time, the pin shaft 29 on the mounting block 27 will push the positioning ring 14 to move, so that the bearing plate 7 starts to rotate and replace. When the pin shaft 29 moves to the other end of the arc-shaped through groove 15, the control valve 34 is opened, so that the elastic air bag 31 can be reset. In addition, it should be noted that during the reset process of the pin shaft 29, since the deflection of the pin shaft 29 towards one side is not restricted, the pin shaft 29 will deflect towards one side, so that the pin shaft 29 can be separated from the previous positioning ring 14, and then can continue to cooperate with the next positioning ring 14. Through the above method, the effective combination of the movement of the plate body 8 and the rotation of the bearing plate 7 is realized, and the requirements of the actual use scenario are also met. The rotation driving member 16 can be in the form of a motor. Of course, it can also be in the form of a pneumatic motor or other forms that can control the rotation of the driving screw 17, such as Figure 4 As shown in Figure 4 , a rectangular opening is provided on the housing 12, and a net plate 35 is fixedly connected in the rectangular opening. Due to the existence of the net plate 35, the inside of the housing 12 communicates with the outside.

[0042] The embodiment of the present invention also provides a probiotic cultivation method, which includes the following steps:

[0043] Step 1: When it is necessary to place the culture dish for cultivating probiotics, the rotation driving member 16 is controlled to work through the display controller 36. The driving screw 17 rotates to drive the plate body 8 to move horizontally, so that the switch door plate 9 is opened, and the plate body 8 carries a bearing plate 7 and moves out of the box body 1;

[0044] Step 2: After the culture dish is placed on the bearing plate 7, the driving screw 17 rotates in the reverse direction, so that the plate body 8 retreats into the box body 1 and resets on the disk body 3. At the same time, the switch door plate 9 resets and closes;

[0045] Step 3: Since the elastic airbag 31 stores gas, when the plate body 8 is reset, the limiting strip 19 is reset, and the annular slideway 6 on the disc body 3 is formed. At this time, the elastic airbag 31 extends, and the positioning ring 14 can be driven to move through the pin shaft 29, and the bearing disc 7 corresponding to the positioning ring 14 rotates, so that the original bearing disc 7 on the plate body 8 is replaced;

[0046] Step 4: After the bearing disc 7 is replaced, the control valve 34 is opened to discharge the gas in the elastic airbag 31. The pin shaft 29 is reset under the material characteristics of the elastic airbag 31 itself. Since the rotation of the pin shaft 29 is not restricted, the pin shaft 29 disengages from the original positioning ring 14. After reaching the initial state, the pin shaft 29 is inserted into another positioning ring 14.

[0047] In one case of this embodiment, the device limits multiple bearing discs 7 through the annular slideway 6 provided on the disc body 3, and this annular structure is also beneficial to the rotation of the bearing discs 7. When a culture dish needs to be placed, the driving component can be used to make the plate body 8 carry a bearing disc 7 and extend. The operator only needs to place the culture dish on the extended bearing disc 7. After the main body carries the bearing disc 7 and resets, the driving component can also control the bearing disc 7 to rotate in the annular slideway 6, so that the bearing disc 7 in the vacant state is located on the plate body 8, which is beneficial to the next storage of the culture dish. To sum up, when the device places the culture dish, it can make the internal space interact less with the outside world, so that the environmental conditions suitable for the growth of probiotics created by the box body 1 are lost less, and the device makes it more convenient and faster for the operator to place the culture dish.
