As shown in
In the present application, by continuous actions of the aforesaid mechanisms, the sample preparation in the sample container 5 is uniformly-mixed and dripped into the test tube 2 to be operated by the next procedure.
In actual use, the aforesaid filtering and ventilating mechanism 1 can specifically adopt the structure as shown in

A working process of the present application is described below according to the specific structures disclosed by the embodiment shown in
When filtering is completed, the filtering jacking mechanism 6-1 moves downwards to return its original location, and the suspension-type test tube 2 synchronously moves downwards to be separated from the sample container 5 and hung on the rotating wheel 4. The filtering and ventilating mechanism 1 moves upwards, and the rebounding mechanism 1-6 moves downwards under the counterforce of the spring 1-3, such that the sample container 5 is separated from the filtering ventilation needle 101, thereby avoiding the sample container 5 from being separated from the uniformly-mixing base. Thus, the whole uniformly-mixing and filtering operation is completed.

The filtering and ventilating mechanism has the rebounding mechanism, which prevents the sample container from being separated from the uniformly-mixing base. The rotating wheel for positioning the suspension-type test tubes can be designed to have one position or have a plurality of positions, such that the requirement for continuously filtering is met.
