[0023] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0024] As shown in Figures 1-4 The embodiment of the present application provides a pretreatment device for determining sodium ions, which is applied to cigarette production, especially to the detection of tobacco. In the production process of a cigarette factory, various detection items are performed, including the determination of the content of sodium ions in tobacco. When the content of sodium ions in tobacco is determined, tobacco powder is placed in a test tube, an extraction reagent is added to the test tube, and after obtaining an extraction liquid, the extraction liquid is collected into a specified container through multiple components such as a connecting pipe and a flow guide pipe. The components such as the test tube, the connecting pipe, the flow guide pipe and the specified container are all made of glass. Therefore, in the entire extraction process and the collection process of the extraction liquid, the flow distance of the extraction liquid is long, so that the extraction liquid is in contact with the glass material for a long time. A certain amount of sodium ions is dissolved in the glass material, which causes the content of sodium ions in the extraction liquid to be unable to accurately reflect the real content of sodium ions in tobacco, resulting in inaccurate determination results of the content of sodium ions in tobacco. The pretreatment device for determining sodium ions provided by the present application aims to avoid the long-time contact between the extraction liquid and the glass material, and to improve the accuracy of the determination of sodium ions in tobacco.

[0025] The pre-treatment device for determining sodium ions comprises an extraction part 11, a filter assembly 12 and a collection part 13. The extraction part 11 has an internal space for containing tobacco and an extraction reagent. The extraction part 11 further has a first opening and a second opening, both of which are in communication with the internal space of the extraction part 11. The filter assembly 12 is arranged on the extraction part 11 and is used to place and maintain tobacco. Liquid can pass through the filter assembly 12. After the filter assembly 12 is placed in the extraction part 11, tobacco is placed on the filter assembly 12, and then an extraction reagent is added to the internal space of the extraction part 11 to soak the tobacco. After obtaining the extraction liquid, the extraction liquid can pass through the filter assembly 12 and flow to the second opening. The collection part 13 also has an internal space for containing the extraction liquid. The collection part 13 further has a third opening in communication with the internal space of the collection part 13. The third opening of the collection part 13 is in communication connection with the second opening of the extraction part 11. Through the communication connection between the second opening and the third opening, the internal space of the collection part 13 and the internal space of the extraction part 11 are in communication. The obtained extraction liquid passes through the filter assembly 12 and flows to the internal space of the collection part 13 through the second opening and the third opening, and the collection of the extraction liquid is completed.

[0026] In this embodiment, the extraction part 11, the filter assembly 12 and the collection part 13 form a more compact structure. The obtained extraction liquid directly flows into the collection part 13, avoiding the flow path of the extraction liquid process, preventing the extraction liquid from contacting the glass material for a long time, and thus significantly reducing the dissolution of sodium ions in the glass material into the extraction liquid, and significantly improving the accuracy of the determination of the sodium ion content in tobacco.

[0027] Preferably, the materials of the extraction part 11 and the collection part 13 are polytetrafluoroethylene. By arranging the extraction part 11 and the collection part 13 made of polytetrafluoroethylene, the contact between the extraction liquid and the glass material is completely avoided, the sodium ions are prevented from dissolving into the extraction liquid, and the content of sodium ions in tobacco is more truly reflected.

[0028] More preferably, the extraction part 11 is located above the collection part 13. After the extraction of tobacco in the extraction part 11 to obtain the extraction liquid, the extraction liquid directly flows downward to the collection part 13 under the action of gravity, and the determination process is more convenient.

[0030] In this way, a symmetrical and compact structure is formed as a whole, which facilitates the storage and placement of the equipment. The top peripheral size of the collection part 13 is smaller than the peripheral size of the extraction part 11, so that a neck structure is formed at the connection between the collection part 13 and the extraction part 11, which facilitates the operator to hold and operate.

[0031] In an embodiment, the filter assembly 12 is a filter paper, the filter paper is arranged on the bottom wall 112, and the filter paper can cover the second opening.
