[0001] The utility model relates to the technical field of bioreactors, and particularly relates to a bioreactor accessory for installing a biochemical detection electrode. Background Technique

[0002] A bioreactor refers to a device that can provide a bioactive environment. It utilizes the biological functions of enzymes or organisms (such as microorganisms) to carry out biochemical reactions in vitro. Bioreactors play an important role in aspects such as liquor production, pharmaceutical production, concentrated jam, fruit juice fermentation, and organic pollutant degradation. In order to effectively operate and control the biochemical process in the bioreactor, pH electrodes, dissolved oxygen electrodes, etc. are often integrated to contact the cell culture solution to real-time feedback the pH and dissolved oxygen concentration of the culture solution. Before installing the detection electrode, it is necessary to check whether there are sediments or impurities on the electrode surface. If so, it needs to be cleaned with pure water to avoid interfering with the reaction. And during the operation and cleaning of the electrode, it is necessary to avoid using any sharp objects or chemical reagents that may damage the electrode to prevent the electrode from being damaged or deformed. In addition, avoid knocking or shaking on the electrode connection interface to prevent abnormal connection.

[0003] For example, the patent with the publication number CN219526653U discloses an electrode installation structure and its bioreactor, which includes an electrode port suspension bracket, an electrode hook assembly, and an electrode bracket assembly.

[0004] However, the electrode installation of the bioreactor in the above technology still has the following problems:

[0005] Before installing the electrode, it is necessary to clean the electrode. Usually, a separate container is prepared during cleaning. The electrode is placed above the container, and pure water is used to rinse the electrode, so that the rinsed pure water falls into the container. During this process, the hand-held electrode may shake, resulting in the electrode colliding with the container wall, causing damage to the electrode and affecting the normal use of the detection electrode. At the same time, only rinsing the electrode with pure water may not be able to wash away the particulate impurities adhered to the outer surface of the electrode, resulting in deviation of the subsequent detection results of the electrode.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0026] Please refer to Figure 1 - Figure 6, A bioreactor accessory for installing biochemical detection electrodes, including a cleaning device and an electrode rod 1 installed inside the cleaning device. The cleaning device includes a pure water bucket 2 and a clamping mechanism. The electrode rod 1 is connected to the clamping mechanism, and the clamping mechanism is connected to the outer wall of the bucket mouth of the pure water bucket 2 and is located inside the pure water bucket 2. A rotating mechanism is connected to the bottom of the pure water bucket 2, and the rotating mechanism is used to drive the pure water inside the pure water bucket 2 to rotate.

[0027] As Figure 1 - Figure 5 shown, a bioreactor accessory for installing biochemical detection electrodes in the present invention is similar in structure to the existing bioreactor accessories for installing biochemical detection electrodes. The main improvement point of the present invention is that the user can better clean the electrode rod 1, thereby improving the use effect of the electrode rod 1. As Figures 1 to 6 shown, when the bioreactor accessory for installing biochemical detection electrodes in the present invention is in use, an appropriate amount of pure water is injected into the pure water bucket 2 for cleaning the electrode rod 1, and the electrode rod 1 is fixed inside the pure water bucket 2 through the clamping mechanism. Subsequently, the rotating mechanism drives the pure water inside the pure water bucket 2 to rotate, and the rotating pure water forms a scouring effect on the outer surface of the electrode rod 1 fixed inside the pure water bucket 2, thereby completing the cleaning of the electrode rod 1 and avoiding possible damage to the electrode rod 1 caused by manual cleaning, and improving the safety of cleaning the electrode rod 1.

[0028] As Figure 4 - Figure 6 shown, the rotating mechanism includes a rotating motor 3 and a rotating disk 4. The rotating motor 3 is fixedly connected to the outer wall of the bottom of the pure water bucket 2, and the output shaft of the rotating motor 3 penetrates through the center position of the bottom surface of the pure water bucket 2 and is fixedly connected to the rotating disk 4. When cleaning the electrode rod 1, the rotating disk 4 located inside the pure water bucket 2 is driven to rotate through the rotating motor 3, thereby driving the pure water inside the pure water bucket 2 to rotate, and thus scouring the inner electrode rod 1 to complete the cleaning operation of the surface of the electrode rod 1.

[0029] As Figure 4 - Figure 6 shown, a plurality of uniformly distributed paddle blades 12 are fixedly connected to the side of the rotating disk 4 away from the rotating motor 3. By installing and fixing a plurality of paddle blades 12 on the rotating disk 4, when the rotating disk 4 rotates, the pure water inside the pure water bucket 2 can be better driven to rotate by driving the plurality of paddle blades 12 to rotate.

[0030] As Figure 1 - Figure 6As shown, a motor cover 5 is fixedly connected to the bottom of the pure water bucket 2. A number of heat dissipation holes 501 are formed through one side of the motor cover 5. The rotary motor 3 is located inside the motor cover 5. Sheathing the motor cover 5 outside the rotary motor 3 can protect the rotary motor 3 and at the same time make the placement of the pure water bucket 2 more stable. Among them, the heat dissipation holes 501 can facilitate the air circulation inside the motor cover 5 and facilitate the diffusion of the heat generated by the operation of the rotary motor 3.

[0031] As Figure 1 - Figure 4 As shown, the clamping mechanism includes a fixed clamping rod 6, a telescopic clamping rod 7 and a connecting ring 14. The fixed clamping rod 6 and the telescopic clamping rod 7 are respectively located on both sides of the pure water bucket 2 and are fixedly connected to the connecting ring 14 at the same time. The connecting ring 14 is sleeved on the pure water bucket 2 and is slidably connected to the outer wall of the pure water bucket 2. One end of the telescopic clamping rod 7 away from the connecting ring 14 and close to the side of the fixed clamping rod 6 is connected with a telescopic assembly. The ends of the telescopic assembly adjacent to the fixed clamping rod 6 are fixedly connected with arc-shaped clamping blocks 8. The end of the electrode rod 1 is located between the two arc-shaped clamping blocks 8. Place the end of the electrode rod 1 between the fixed clamping rod 6 and the telescopic clamping rod 7, and drive the arc-shaped clamping block 8 to approach the other arc-shaped clamping block 8 by the telescopic assembly, so as to clamp and fix the electrode rod 1. And after the clamping and fixing of the electrode rod 1 is completed, the height of the electrode rod 1 can be adjusted by sliding the connecting ring 14 up and down on the outer wall of the pure water bucket 2.

[0032] As Figure 1 - Figure 4 As shown, both of the two arc-shaped clamping blocks 8 are rubber blocks. By making the arc-shaped clamping blocks 8 of rubber blocks, it is possible to reduce the extrusion damage to the end of the electrode rod 1 while clamping and fixing the end of the electrode rod 1.

[0033] As Figure 1 - Figure 4 As shown, the telescopic assembly includes a telescopic rod 9, a telescopic spring 10 and a stopper 11. One end of the telescopic rod 9 is fixedly connected to the arc-shaped clamping block 8, and the other end sequentially passes through the telescopic clamping rod 7 and the telescopic spring 10 and is fixedly connected to the stopper 11. The two ends of the telescopic spring 10 are respectively fixedly connected to the telescopic clamping rod 7 and the stopper 11. The telescopic spring 10 drives the stopper 11 to move inward, and then drives the telescopic rod 9 to slide inward, driving the arc-shaped clamping block 8 to clamp and fix the electrode rod 1.

[0034] As Figure 4 As shown, an anti-touch net 13 is fixedly connected to the inner wall of the pure water bucket 2, and the anti-touch net 13 is located above the rotating mechanism. Installing and fixing the anti-touch net 13 above the rotating mechanism can prevent the lower end of the electrode rod 1 from coming into contact with the rotating mechanism during installation and avoid collision damage to the electrode rod 1 when the rotating mechanism rotates.

[0035] As Figure 1 -Figure 6 As shown, a threaded hole 101 is penetratingly formed on one side of the connecting ring 14. A hand-tightening bolt 15 is in threaded connection with the threaded hole 101. The threaded rod of the hand-tightening bolt 15 penetrates through the threaded hole 101 and abuts against the outer wall of the pure water bucket 2. When the connecting ring 14 drives the electrode rod 1 to move up and down in the pure water bucket 2 for adjustment, the hand-tightening bolt 15 can be screwed inward in the threaded hole 101 and extrude against the outer wall of the pure water bucket 2, so as to fix the connecting ring 14 on the outer wall of the pure water bucket 2.

[0036] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
