[0017] The technical scheme of the utility model will be described clearly and completely in connection with embodiments, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the utility model.

[0018] Please refer to Figures 1-4 The utility model provides a kind of technical scheme:

[0019] A kind of rapid solvent extractor facilitating reagent collection bottle position adjustment, since the structure composition and working principle of rapid solvent extractor 101 are prior art, so other structure composition and working principle about rapid solvent extractor 101 in this embodiment are not described in detail.

[0020] In this embodiment, a plurality of drainage pipes 201 are installed on one side of the rapid solvent extractor 101. Each drainage pipe 201 is connected with a puncture needle 301 at one end and communicates with the extraction pool of the rapid solvent extractor 101 at the other end. In this way, the sample liquid treated by the extraction process can be drained into the drainage pipe 201 and then drained into the corresponding collection bottle through the puncture needle 301.

[0021] In order to facilitate the alignment of the puncture needle 301 when collecting solution by different types of collection bottles, and facilitate the replacement of the test tube rack 401 on which the collection bottles are installed, a lifting mechanism is installed on one side of the rapid solvent extractor 101 in this embodiment. The lifting mechanism specifically includes a motor 601 installed on the rapid solvent extractor 101, a lead screw 602 in transmission connection with the output shaft of the motor 601, a cross arm 603 in threaded connection with the lead screw 602, and two cantilever arms 604 installed at both ends of the cross arm 603. A guide rod is installed on the rapid solvent extractor 101, the cross arm 603 is in sliding connection with the guide rod, and the central axis of the guide rod is parallel to the central axis of the lead screw 602. Two counterbores 701 adapted to the cantilever arms 604 are arranged on one side of the test tube rack 401, and the two cantilever arms 604 are respectively inserted into the two counterbores 701. A plurality of placement holes for placing collection bottles are arranged on the test tube rack 401. A distance sensor is also installed below one of the cantilever arms 604 on the rapid solvent extractor 101. In this embodiment, the distance sensor is a Japanese Shinshin reflective photoelectric sensor CX-440 series. This series of sensors has the characteristics of high precision, no color influence and long distance detection. It can detect a height difference as small as 0.4mm, and does not need to adjust the controller when different color objects move. Its detection distance can reach 300mm, which is 1.5 times the detection distance of similar products.

[0022] In this way, after placing a plurality of collection bottles on the test tube rack 401, the two cantilever arms 604 are inserted into the two counterbores 701, the test tube rack 401 is gradually pushed to move, and the alarm parameters of the distance sensor are set in advance. During this process, the distance sensor detects the distance between one side of the test tube rack 401 and the rapid solvent extractor 101. When the mouth of the collection bottle placed on the test tube rack 401 is aligned with the corresponding puncture needle 301, the distance sensor triggers an alarm, and the pushing of the test tube rack 401 is stopped. Figures 1-4From the perspective of the device, the motor 601 then starts the control screw 602 to rotate, thereby controlling the horizontal arm 603 to move upward (i.e., towards the puncture needle 301). The upward movement of the horizontal arm 603 drives the test tube rack 401 upward through the cantilever 604 until each puncture needle 301 is inserted into each collection bottle, and the solution in the drain tube 201 is drained into the collection bottle through the puncture needle 301. When it is necessary to change to a different type of collection bottle, a different test tube rack 401 is required. At this time, the current test tube rack 401 is "pulled out" and replaced with the corresponding test tube rack 401.

[0023] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
