[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0030] Combine Figure 1-Figure 3A stirrer for a biological reaction system with a lifting function includes a connecting frame 1 and a driving motor 2 fixedly connected to the bottom of the connecting frame 1. The output end of the driving motor 2 is fixedly connected to a transmission shaft 21. A stirring blade 22 is provided below the transmission shaft 21. An adjustment mechanism is provided inside the transmission shaft 21. The adjustment mechanism can facilitate staff to adjust the stirring position. The adjustment mechanism includes a placement port 211 opened inside the transmission shaft 21. The placement port 211 is fixedly connected to the adjustment motor 212.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example 1:

[0033] In order to solve the problem that most existing stirrers have a single structure and only have the function of stirring, and when facing containers of different depths, it is inconvenient to perform stirring operations, which greatly affects the subsequent work process, this embodiment discloses the following technical solutions, specifically as follows: Figure 1-Figure 3 As shown, the output end of the adjustment motor 212 is fixedly connected to a threaded rod 213, and the outer side of the threaded rod 213 is threadedly connected to a sliding column 214. A limiting groove 215 is provided on one side of the sliding column 214, and the sliding column 214 is slidably connected to the inside of the placement port 211 through the limiting groove 215. When the device is used, the connecting frame 1 can be fixed in a specified position. When the stirring operation is performed, the driving motor 2 can be started at this time, and the driving motor 2 drives the sliding column 214 to rotate through the transmission shaft 21, thereby causing the stirring blade 22 to rotate. At this time, the stirring blade 22 can have a stirring effect. When the position of the stirring blade 22 needs to be moved, the adjustment motor 212 inside the transmission shaft 21 can be started at this time, and the adjustment motor 212 drives the threaded rod 213 to rotate, thereby causing the sliding column 214 to slide inside the placement port 211. At this time, the sliding column 214 extends from the inside of the placement port 211, thereby causing the height of the stirring blade 22 to change, thereby realizing the ability to change the height of the stirring blade 22 according to the height of different containers, thereby improving the use effect.

[0034] Example 2:

[0035] In order to solve the problem that most of the existing stirrers are fixed on the output end of the stirring mechanism, which is inconvenient to use when the stirrer needs to be removed for disinfection, affecting the overall disinfection effect, this embodiment discloses the following technical solutions, specifically as follows: Figure 4 and Figure 5The top of the stirring blade 22 is provided with a connecting groove 221, and the interior of the connecting groove 221 is fixedly connected to a clamp 222, and the clamp 222 is provided with two groups. The threaded rod 213 is penetrated by a placement groove 23, and the interior of the placement groove 23 is slidably connected to a toggle plate 231, and the top of the toggle plate 231 is fixedly connected to a spring rod 232, and the other end of the spring rod 232 is fixedly connected to the interior of the placement groove 23, and the bottom of the toggle plate 231 is slidably connected to a trapezoidal block 233, and the trapezoidal block 233 is provided with two groups, and the trapezoidal block 233 is slidably connected to the interior of the transmission shaft 21, and one side of the trapezoidal block 233 is fixedly connected to a limiting block 234, and the limiting block 234 slides with the clamp 222. When the disinfection operation needs to be performed, the toggle plate 231 inside the placement groove 23 can be moved. When the stirring blade 22 needs to be installed, the connecting groove 221 on the stirring blade 22 can be aligned with the sliding post 214 and moved. Due to the setting of the trapezoidal surface of the limit block 234, when the clamp 222 inside the connecting groove 221 contacts the limit block 234, the limit block 234 will be engaged with the clamp 222 under the action of the spring rod 232. At this time, the installation of the stirring blade 22 is completed, and the stirring blade 22 can be removed from the sliding post 214 when disinfection is required, thereby improving the disinfection effect.
