[0002] A bioreactor is a device designed specifically for biochemical processes that provides a controlled environment in which organisms (such as microorganisms, animal cells, plant cells or enzymes) can carry out specific biochemical reactions or grow and reproduce.

[0005] Most current bioreactors have a feeding pipe on the top cover to add fluid materials into the reactor. However, the materials inside the bioreactor are diverse, and some fluid materials cannot contact each other before being added to the bioreactor (for example, two materials may react, so a third material is needed to neutralize or delay the reaction). However, the above-mentioned bioreactor has only one feeding hole, which means that when some fluid materials are added, they are likely to react prematurely, thereby affecting the subsequent reaction effect inside the bioreactor, which is very inconvenient.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figure 1-Figure 3 , a bioreactor accessory for convenient feeding, including several material storage barrels 8 installed on the upper surface of the reactor body 1 and the sealing cover 2, a positive rotation rod 3 is installed on the upper surface of the sealing cover 2, the upper surface of the positive rotation rod 3 is connected with a suction mechanism, the output end of the suction mechanism is connected with a diversion component, the upper surfaces of the several material storage barrels 8 are fixedly connected and communicated with a connecting ring 13, one end of the diversion component away from the suction mechanism is communicated with the several connecting rings 13, the bottom surfaces of the several material storage barrels 8 are fixedly connected and communicated with a supporting tube 10, the other ends of the several support tubes 10 are fixedly connected to the upper surface of the sealing cover 2, and are communicated with the interior of the reactor body 1, the side of the several material storage barrels 8 away from the positive rotation rod 3 is connected with an external pipe 9, the inner walls of the several material storage barrels 8 are slidably connected with a sealing plug 14, and an electromagnetic valve 11 is arranged in the external pipe 9, the support pipe 10 and the diversion component.

[0021] The bioreactor accessory for convenient feeding in the utility model is similar to the structure of the existing bioreactor, such as a bioreactor disclosed in the patent with publication number CN220335170U. Figures 1 to 3 As shown, when the bioreactor accessory for convenient feeding in the utility model needs to add fluid materials into the reactor body 1, it only needs to turn on the suction mechanism through the controller of the reactor body 1 itself. After the suction mechanism is started, the sealing plugs 14 inside the corresponding storage barrels 8 can be controlled to descend through the diversion components, and then the fluid materials inside the storage barrel 8 can be pushed into the reactor body 1 through the sealing plugs 14. During the pushing of the fluid materials, they will not contact each other, thereby avoiding the occurrence of premature reactions between the materials.

[0022] Special mention should be made here:

[0023] 1. During use, the solenoid valves 11 can be electrically connected to the controller, so that when materials need to be transported, the solenoid valves 11 of the support tube 10 below the storage barrel 8 can be opened accordingly, thereby preventing the materials from being discharged from the support tube 10 by themselves.

[0024] 2. The controller can use the currently commonly used PLC controller. Since it is a very mature technology, it will not be explained in detail.

[0025] 3. The purpose of setting the solenoid valve 11 and also setting the suction mechanism and the sealing plug 14 is to take into account that some fluid materials have high viscosity and may not be able to flow out from the inside of the support tube 10 after the solenoid valve 11 on the support tube 10 is opened by its own gravity, or the flow is too slow, affecting the addition efficiency.

[0026] 4. The external pipe 9 can add materials from the external material barrel to the storage barrel 8 in time after the materials inside the storage barrel 8 are used up; and during the normal use of the storage barrel 8, the external pipe 9 is always sealed by the electromagnetic valve 11.

[0027] Please refer to Figure 1 The air suction mechanism includes a base 4, an air pump 5 and an air outlet pipe 12. The bottom surface of the base 4 is fixedly connected to the upper surface of the positive rotating rod 3, the upper surface of the base 4 is fixedly connected to the outer wall of the air pump 5, the output end of the air pump 5 is fixedly connected and connected to one end of the air outlet pipe 12, and the other end of the air outlet pipe 12 is connected to the diversion component.

[0028] More specifically, when it is necessary to control the discharge of materials, it is only necessary to turn on the air pump 5 through the controller. The air pump 5 will deliver gas to the outside, which will enter the diversion component through the outlet pipe 12 and then be accurately delivered to the corresponding storage barrel 8 through the diversion component, so that the sealing plug 14 inside the storage barrel 8 can be pushed down.

[0029] Please refer to Figure 1 The flow distribution component includes a multi-way tube 6 and a plurality of connecting tubes 7. One end of the multi-way tube 6 is connected to an end of the air outlet pipe 12 away from the air pump 5. The other ends of the multi-way tube 6 are respectively connected to one end of the plurality of connecting tubes 7. The other ends of the plurality of connecting tubes 7 are respectively connected to a plurality of connecting rings 13.

[0030] More specifically, after the gas is exhausted from the gas outlet pipe 12 , it will first enter the multi-way pipe 6 and then be transported to the storage barrel 8 through the corresponding connecting pipe 7 .

[0031] Please refer to Figure 1 The outer wall of the external pipe 9 is threadedly connected to the inner wall of the storage barrel 8, and the inner wall of the multi-way pipe 6 is threadedly connected to the outer walls of the air outlet pipe 12 and the plurality of connecting pipes 7.

[0032] More specifically, the threaded connection can ensure a stable connection while facilitating disassembly and installation.

[0033] Please refer to Figure 1 The support pipe 10, the air outlet pipe 12, the multi-way pipe 6 and the plurality of connecting pipes 7 are all hard pipes.

[0034] More specifically, by setting it as a hard tube, during the process of air pump 5 pumping or exhausting air, it will not affect the support tube 10, the air outlet pipe 12, the multi-way tube 6 and the plurality of connecting tubes 7, causing them to compress or expand.

[0035] Please refer to Figure 1 The plurality of storage barrels 8 are all made of transparent glass, and the outer walls of the plurality of storage barrels 8 are provided with scale lines 801 .

[0036] More specifically, by setting up transparent glass and scale lines 801, the remaining amount of material inside the storage barrel 8 can be intuitively understood from the outside, making it convenient to add material from the external pipe 9.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
