[0022] 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 described embodiments 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 belong to the scope of protection of the present invention.

[0023] The storage bottle in the embodiment of the present invention can automatically open the lid and perform double filtration and separation on the sample. A separation membrane cup and an impurity filtering membrane cup are arranged in the bottle body to filter the liquid in the storage bottle, thereby achieving the purpose of quickly obtaining the required target substance.

[0024] like Figure 1 - Figure 6 As shown, a preservation bottle that can automatically open the lid and perform double filtration and separation on the sample comprises a bottle cap 1 and a bottle body 2, wherein the bottle cap 1 is arranged at the upper end of the bottle body 2, and a separation membrane cup 3 and an impurity filtering membrane cup 4 are arranged in the bottle body 2, wherein the upper end of the separation membrane cup 3 is connected to the bottle cap 1, and the impurity filtering membrane cup 4 is sleeved on the lower end of the separation membrane cup 3, and a first filter membrane 5 is arranged at the lower end of the impurity filtering membrane cup 4, and a second filter membrane is arranged at the lower end of the separation membrane cup 3, and at the same time, a sealing portion 11 is arranged at the upper end of the bottle cap 1, and the position of the sealing portion 11 is arranged corresponding to the separation membrane cup 3.

[0025] In actual use, the sample is added to the preservation bottle, the first filter membrane 5 performs impurity filtering operation on the sample, and the second filter membrane performs targeted negative pressure separation and adsorption on the sample material from which the impurities are removed, thereby separating the targeted substances in the sample. During negative pressure adsorption, the pipeline is passed through the sealing part 11 and inserted into the separation membrane cup 3, which is very convenient to operate.

[0026] In some embodiments, the sealing portion 11 includes a rubber sealing pad or an aluminum foil, which not only has good sealing properties but can also be penetrated during negative pressure separation and adsorption.

[0027] At the same time, a fixing part 21 is arranged at the lower end of the bottle body, and the fixing part 21 is arranged on the outer wall of the bottle body. The bottle body 2 can be firmly fixed by the fixing part 21, so as to facilitate the rotation, fixing and positioning needs of the opening mechanism when opening the cover.

[0028] like Figure 2 and Figure 3 As shown, a rotating member 12 is provided on the inner wall of the bottle cap 1, and a clamping member 22 is provided at a corresponding position of the bottle body 2. The rotating member 12 is provided along the inner wall of the bottle body and spirals downward. When the bottle cap 1 rotates, the rotating member 12 is clamped with the clamping member 22, and the bottle cap 1 is tightened as it is rotated, thereby fixing the bottle cap 1.

[0029] At the same time, a rotating cover opening portion 13 is provided on the outer wall of the bottle cap 1 , which can open the bottle cap 1 .
