The spray ring tube 42 is coaxially arranged with the barrel body 1, and is located between the end portion of the stirring paddle 32 and the inner side wall of the barrel body 1, the spray ring tube 42 is in the form of a ring-shaped tube body provided with a plurality of interval distributed spray holes 421, the lifting branch pipe 43 is parallelly arranged with the axis of the barrel body 1, and vertically penetrates through the top wall of the barrel body 1, the lifting branch pipe 43 is fixedly connected with the spray ring tube 42, and is in communication with the spray holes 421 of the spray ring tube 42, and the lifting branch pipe 43 is partially arranged in the sleeve seat 41 in a liftable manner.

[0034] Optionally, in some embodiments, the lifting branch pipe 43 is connected with the spray ring tube 42 in an integral structure.

[0035] Further, the lifting branch pipe 43 is provided in a plurality of number and is uniformly and interval arranged in the circumferential direction, and specifically, in this embodiment, the lifting branch pipe 43 is provided in two number and is centrally symmetrically distributed about the axis of the barrel body 1, so as to improve the stability and reliability of the connection with the spray ring tube 42.

[0036] As shown in the figures of Figure 2 , Figure 3 and Figure 4 , the sleeve seat 41 is fixedly connected with the barrel body 1, the sleeve seat 41 is provided with a coaxially arranged outer clamping sleeve layer 411 and an inner flow channel layer 412, the lifting branch pipe 43 is movably arranged in the outer clamping sleeve layer 411, the inner flow channel layer 412 is in communication with the lifting branch pipe 43, so that the inner flow channel layer 412 is in communication with the spray ring tube 42 through the lifting branch pipe 43, so as to spray the high-pressure cleaning liquid or gas injected through the inner flow channel layer 412 into the accommodating cavity through the spray holes 421, and blow and clean the stirring paddle 32 and the inner wall of the barrel body 1, the sleeve seat 41 is provided with an external source interface 413 at the end thereof, which is in communication with the inner flow channel layer 412, so as to externally introduce the high-pressure liquid or high-pressure gas for blowing and cleaning.

[0038] As shown in Figure 2 The cleaning assembly 4 further includes a transmission unit movably connected with the lifting branch pipe 43. The transmission unit includes a driving gear 44 connected with the output shaft of the driving motor 31, and a driven gear 45 threadedly connected with the lifting branch pipe 43.

It should be noted that during the normal heat sterilization process of the reagent solution, the reagent solution does not need to be stirred throughout the process, but only needs to be stirred intermittently. Since the spraying ring pipe 42 moves synchronously, the spraying ring pipe 42 also plays a certain stirring role during the lifting process. In addition, if it is not desired to drive the spraying ring pipe 42 to move up and down during the normal heat sterilization process, it is only necessary to disconnect the connection between the driving gear 44 and the output shaft of the driving motor 31, or to disconnect the connection between the driving gear 44 and the driven gear 45. Here, no further elaboration is given.
