Further, the protrusion 21 is inclined towards the proximal end, and the insertion space is formed between the protrusion 21 and the inner wall of the bottle cap 2, the entrance position of the insertion space is spaced apart from the wall thickness of the bottle neck 12, which facilitates the insertion of the bottle neck 12. In the embodiment, the protrusion 21 is preferably made of PVC material with good elasticity, when the bottle cap 2 is screwed onto the bottle neck 12, the top end of the bottle neck 12 can be inserted into the insertion space, and as the insertion depth increases, the protrusion 21 is deformed by extrusion, so that it is sealed at the bottle opening position. This structure can significantly improve the sealing effect of the liquid storage bottle, prevent liquid leakage and reduce the risk of sample contamination.

[0026] The liquid inlet and outlet assembly 3 includes at least three groups of pipelines, which are fixedly connected to the bottle cap 2. For example, the three groups of pipelines include an exhaust pipeline 31, a liquid inlet pipeline 32 and a liquid outlet pipeline 33. According to actual operation needs, a plurality of pipelines can also be provided, for example, the liquid inlet pipeline 32 or the liquid outlet pipeline 33 is provided as two groups.

[0027] Specifically, the bottle cap 2 is provided with a through hole for installing the pipeline, and each pipeline is connected to the through hole. In order to prevent the pipeline from falling off and ensure the sealing of the pipeline connection, a sealing flange is fixedly arranged on the pipeline in the circumferential direction. In another embodiment, the pipelines can be integrally connected with the bottle cap 2 when the bottle cap 2 is injection molded.

[0028] The exhaust pipeline 31 is used to connect the exhaust or negative pressure pipeline.

[0029] The liquid outlet pipeline 33 is used to assist the liquid in the liquid storage bottle to be discharged. In the embodiment, the liquid inlet and outlet assembly 3 further includes a liquid suction pipe 34 connected to the bottom end of the liquid outlet pipeline 33. The liquid suction pipe 34 is a hard pipe, and the use of a hard material can ensure that the liquid suction pipe 34 extends to the preset position without bending. The liquid suction pipe 34 includes a liquid suction connection section and a liquid suction section, which are preferably integrally formed. The liquid suction connection section is vertically arranged and is used to connect the liquid outlet pipeline 33, and the liquid suction section is bent and arranged, the top of which is integrally connected to the liquid suction connection section, and the bottom extends to the bottom edge or corner position of the bottle body 11. In the embodiment, by connecting the liquid suction pipe 34 to the bottom end of the liquid outlet pipeline 33, and adopting the design of bending to the bottom, the liquid residual dead volume can be greatly reduced, and the residual ratio can be reduced to 0-0.5%.

[0030] Preferably, in the embodiment, the liquid suction pipe 34 is made of thermoplastic plastic material, for example, PVC or PP material. The thermoplastic plastic material not only has good corrosion resistance and can resist the corrosion of various chemicals, but also can make the liquid suction pipe 34 have a certain hardness while being elastically deformed, so that it can be adapted to the liquid storage bottle with a pointed bottom or a flat bottom.

[0031] In the embodiment, the liquid suction pipe 34 and the liquid outlet pipeline 33 can be connected by plug-in, bonding or other connection methods. It can be understood that, in order to facilitate the disassembly and replacement of the liquid suction pipe 34, the liquid suction pipe 34 and the liquid outlet pipeline 33 are preferably connected in a detachable manner such as plug-in.

[0032] The liquid inlet pipeline 32 is used to inject liquid such as sample into the liquid storage bottle. In actual application, liquid splashing is prone to occur during the injection process. The splashed liquid may affect the accuracy of the liquid concentration and also affect the user's observation line of sight inside the bottle body 11. Therefore, as shown in Figure 2 and Figure 3 In the embodiment, the liquid inlet and outlet assembly 3 further comprises an injection pipe 35 connected to the bottom end of the liquid inlet pipeline 32. The injection pipe 35 is a hard pipe. The use of hard material can ensure that the injection pipe 35 extends to the preset position without bending. The injection pipe 35 further comprises an injection connecting section and an injection section. The injection connecting section is vertically arranged and is used to connect the liquid inlet pipeline 32. The injection section is arranged in a bent manner, the top of which is integrally connected to the injection connecting section, and the bottom extends to the inner side wall of the bottle body 11. It should be noted that the outlet end of the injection section should not be completely blocked by the inner side wall of the bottle body 11 to prevent liquid from flowing out. In the embodiment, by arranging the injection pipe 35 abutting against the inner side wall of the bottle body 11, when liquid sample flows out of the injection pipe 35, it slowly flows along the inner side wall of the bottle body 11, thereby effectively preventing liquid splashing.

[0033] The injection pipe 35 and the liquid inlet pipeline 32 can be connected by plug-in, bonding or other connection methods. It can be understood that, in order to facilitate the disassembly and replacement of the injection pipe 35, the injection pipe 35 and the liquid inlet pipeline 32 are preferably connected in a detachable manner such as plug-in.

[0034] In actual application, the liquid inlet pipeline 32 is externally connected with a filter and liquid sample, the liquid outlet pipeline 33 is externally connected with a peristaltic pump, and the exhaust pipeline 31 is connected with a negative pressure structure. Under the drive of the negative pressure structure, the liquid sample slowly flows into the bottle body 11 through the filter, the liquid inlet pipeline 32 and the injection pipe 35. When the volume of the liquid inside the bottle body 11 reaches a predetermined value, the exhaust pipeline 31 is disconnected from the negative pressure structure, the pressure inside the bottle body 11 returns to normal, and then the peristaltic pump is started. The liquid in the bottle body 11 is sequentially transferred to the target container through the liquid suction pipe 34 and the liquid outlet pipeline 33, and the liquid in the bottle is finally emptied.

[0035] The transfer liquid bottle provided by the embodiment can realize automatic injection and discharge of liquid sample by setting the liquid inlet and outlet assembly 3 on the bottle cap 2, without manually opening the bottle cap 2 to pour liquid, thereby saving operation time and effectively reducing the risk of bacterial contamination caused by opening the bottle cap. Further, by setting the plug-in space matched with the bottle opening at the bottom of the bottle cap 2 and the elastic convex part 21 structure, the sealing effect of the bottle can be further ensured, liquid leakage can be prevented, and the risk of contamination can be reduced. By setting the liquid suction pipe 34 capable of bending to the bottom connected with the liquid outlet pipeline 33, the residual volume of liquid can be greatly reduced, and the residual ratio can be reduced to 0-0.5%; by setting the liquid injection pipe 35 abutting against the inner side wall of the bottle body 11, the liquid sample can flow along the inner side wall of the bottle body 11, thereby effectively preventing the liquid sample from splashing.
