[0002] Extraction is a unit operation for separating mixtures by taking advantage of the different solubilities of components in a system in a solvent. The organic extraction agent added to the solution to be separated usually has volatility and generates poisonous gases harmful to the human body. Therefore, the extraction operation in the environmental detection engineering experiment process usually needs to be carried out in a fume hood. Shaking the solution during extraction is a necessary operation. However, the movable door of the fume hood should remain half-open during ventilation, and the experimenter cannot lift the extraction bottle to the chest for shaking. It is inconvenient to shake in a lower and narrower area, and the funnel support with a vibration mechanism has a large specification and is usually inconvenient to put in or cannot be put into the fume hood. Therefore, a fume hood which is convenient for extraction and separation during the extraction of bioactive substances is proposed to solve the above problems. Content of the Utility Model

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model.

[0017] Please refer to Figures 1-4 , a fume hood for facilitating extraction and separation during the extraction of bioactive substances in the present application, including a cabinet body 1. A storage cavity is provided inside the cabinet body 1. An extraction mechanism 2 is provided in the storage cavity in a lifting manner. A cover plate is movably provided at the upper port of the storage cavity to drive the cover plate to open and close the storage cavity. The extraction mechanism 2 includes a telescopic assembly to contract and fold itself to reduce the volume.

[0018] When the fume hood is ventilated, the movable door 11 needs to be lowered to reduce the path of toxic gas overflow, so as to ensure that the equipment is used above the safety baseline. However, the space where the user can reach in with their hands becomes low and narrow. The device is provided with a storage cavity and a movable cover plate. When extraction is not required, it maintains a complete working platform of the fume hood for convenient use. When extraction is required, the cover plate is opened, and the extraction mechanism 2 for oscillating the extraction bottle 3 is raised. This design eliminates the need for the user to hold the extraction bottle 3 and oscillate it manually, nor is it necessary to place a large extraction device, solving the problems of inconvenient placement or operation usually. There are several embodiments for the design of lifting the extraction mechanism 2, such as a cylinder or a fork-shaped lifting frame connected to the base 26, with the extraction mechanism 2 arranged on the base 26, so that when the lifting component moves up and down, it drives the extraction mechanism 2 to rise or be stored. The above designs are all conventional designs in the art and not the innovative invention points of this application, so they will not be elaborated here. By folding the extraction mechanism 2, the space occupied by the extraction mechanism 2 when it is idle is further reduced, making the space allocation of the device possible and reasonable;

[0019] Please refer to Figure 1 , an operation opening can also be provided on the movable door 11 of this application. An operation window 111 for opening and closing the operation opening is movably arranged on the operation opening, and a dial block is provided on the operation window 111, so that it is convenient for the user to lift and press the dial block to open and close the operation opening.

[0020] In this application, the telescopic component can adopt various embodiments that can be telescoped and folded to change the occupied volume. Please refer to Figure 4 , the preferred telescopic component of this application includes a telescopic rod 22. The telescopic rod 22 is hollow and has threads inside. A screw rod 23 is threadedly connected to the cavity of the telescopic rod 22, so that when the screw rod 23 rotates, it can move out of and into the telescopic rod 22.

[0021] The device is provided with a threaded groove on the telescopic rod 22 and is set as a threaded sleeve rod, and the screw rod 23 is used in threaded cooperation with it to change the overall volume of the extraction mechanism 2.

[0022] Furthermore, sliding blocks 24 are respectively slidably arranged on the telescopic rod 22 and the screw rod 23, and a fixing frame 25 is fixedly arranged at one end of the sliding block 24.

[0023] The structure of the sliding block 24 in this device is composed of two clamping blocks. A screw rod 23 is arranged between the clamping blocks, and the screw rod 23 is threadedly connected to the clamping blocks. In this way, when the screw rod 23 rotates, the screw rod 23 can be received into the clamping blocks or moved out of the clamping blocks to change the distance between the two clamping blocks. Thus, when the sliding block 24 is loose, it can move up and down on the telescopic rod 22 or the screw rod 23 to adjust to a suitable position, and when the clamping blocks are tightened, the position of the sliding block 24 can be fixed.

[0024] Furthermore, an annular flexible wrapping member is arranged inside the fixing frame 25.

[0025] By providing a flexible wrapper, such as materials like rubber and sponge, the device reduces rigid contact when the extraction bottle 3 is inserted and during oscillation. Moreover, due to the good wrapping property of these materials, after the extraction bottle 3 is inserted, it has a certain elasticity, which can enhance the fixation of the extraction bottle 3.

[0026] Furthermore, it further includes a telescopic sleeve 21, a telescopic rod 22 is slidably disposed within the telescopic sleeve 21, and a vibrator (not shown in the figure) is provided within the telescopic sleeve 21, and the vibrator is connected to the telescopic rod 22.

[0027] By disposing the telescopic rod 22 within the telescopic sleeve 21 and connecting a vibrator between the two, the device can, after fastening the extraction bottle 3, start the vibrator to replace manual oscillation and mixing of the extraction bottle 3, making it more convenient to use.

[0028] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
