DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0021] Combination Figure 1-Figure 2 A food-borne stimulant extraction tube comprises a glass tube body 1, inside of which a filter component 4 for improving separation effect is movably arranged.

[0022] The utility model is further described below in conjunction with embodiments.

[0023] Embodiment 1:

[0024] See also Figure 1-Figure 4 The filter assembly 4 includes a first fixing block 41, a second fixing block 42 fixedly connected to the bottom end of the first fixing block 41, a connecting column 43 fixedly connected to the bottom end of the second fixing block 42, a mounting plate 44 fixedly connected to the bottom end of the connecting column 43, a filter plate 45 movably connected to the outer surface of the mounting plate 44, a filter hole 46 provided on the outer surface of the filter plate 45, and a connecting ring 47 fixedly connected to the outer surface of the filter plate 45. The diameter of the second fixing block 42 is equal to the diameter of the first fixing block 41, the diameter of the first fixing block 41 is equal to the inner diameter of the glass tube body 1, the connecting ring 47 contacts the inner wall of the glass tube body 1, and the filter plate 45 divides the glass tube body 1 into The filter plate 45 is located inside the glass tube body 1 in the initial state. The filter plate 45 is convenient for separating the extractant adsorbed with impurities from the extract during the extraction process. The extract flows into the bottom of the glass tube body 1 through the filter hole 46, while the extractant adsorbed with impurities is blocked at the top of the extract by the filter hole 46. When the filter plate 45 needs to be cleaned, the first fixed block 41 is pulled upward. The first fixed block 41 moves upward to drive the connecting column 43 to move upward, thereby driving the connecting ring 47 to slide along the inner wall of the glass tube body 1, and the connecting ring 47 is pulled out of the glass tube body 1 to facilitate cleaning of the filter plate 45.

[0025] A forward threaded channel 421 is provided on the outer surface of the second fixing block 42, and a reverse threaded channel 13 is provided on the inner wall of the glass tube body 1. The reverse threaded channel 13 is arranged corresponding to the forward threaded channel 421. When the filter plate 45 is located inside the glass tube body 1, the first fixing block 41 is rotated to drive the second fixing block 42 to rotate, so that the forward threaded channel 421 is matched with the reverse threaded channel 13. At this time, the first fixing block 41 is fixed to the top of the glass tube body 1 to prevent liquid from spilling out during the oscillation process.

[0026] The connecting ring 47 is a component made of rubber material. The rubber material has certain elasticity and wear resistance, which is convenient for reducing the friction loss when the connecting ring 47 contacts the inner wall of the glass tube body 1, and helps to extend the service life of the glass tube body 1.

[0027] A first pipette 2 is fixedly passed through the outer surface of the glass tube body 1. One end of the first pipette 2 is movably connected to a first syringe 21. The first syringe 21 is located in the first cavity 11. Pulling the first syringe 21 facilitates taking out the extractant adsorbed with impurities through the first pipette 2.

[0028] A second pipette 3 is fixedly passed through the outer surface of the glass tube body 1, and one end of the second pipette 3 is movably connected to a second syringe 31. The second pipette 3 is arranged in the second cavity 12. Pulling the second syringe 31 facilitates the removal of the extraction liquid through the second pipette 3, thereby speeding up the liquid removal process and improving work efficiency.

[0029] The outer surface of the glass tube body 1 is covered with an anti-skid cover 5 , which increases the friction between the hand and the glass tube body 1 , making it easier to take the glass tube body 1 and preventing the glass tube body 1 from slipping out of the hand.

[0030] When in use, the sample to be tested and the extractant are placed inside the glass tube body 1, and the first fixed block 41 is rotated, thereby driving the second fixed block 42 to rotate, so that the forward threaded channel 421 is matched with the reverse threaded channel 13. At this time, the first fixed block 41 is fixed to the top of the glass tube body 1 to prevent the liquid from spilling out during the oscillation process. During the extraction process, the filter plate 45 is convenient for separating the extractant adsorbed with impurities from the extracting liquid. The extracting liquid flows into the bottom of the glass tube body 1 through the filter hole 46, and the extractant adsorbed with impurities will be blocked by the filter hole 46 at the top of the extracting liquid. The second syringe 31 is pulled to facilitate the extraction of the extracting liquid through the second pipette 3, which speeds up the liquid extraction process and improves the work efficiency. When the filter plate 45 needs to be cleaned, the first fixed block 41 is pulled upward. The first fixed block 41 moves upward to drive the connecting column 43 to move upward, thereby driving the connecting ring 47 to slide along the inner wall of the glass tube body 1, and the connecting ring 47 is pulled out of the glass tube body 1, so as to facilitate the cleaning of the filter plate 45, thereby solving the problem that the filtering effect of the filtering structure decreases after long-term use, thereby affecting the purity of the extracting liquid.
