Description

TECHNICAL FIELD

[0001] The utility model relates to extraction device technical field, concretely is a kind of extraction device for cosmetic detection pretreatment. BACKGROUND

[0002] In the cosmetic detection process, the pretreatment of sample is a crucial link.Effective pretreatment method can not only improve the extraction efficiency of target substance, but also ensure the accuracy and consistency of detection results.As a commonly used liquid-liquid extraction tool, separatory funnel is widely used in extraction and separation of cosmetic samples.However, there are certain limitations in the operation of traditional separatory funnel, such as tedious manual operation, poor fixing of separatory funnel with different sizes, insufficient mixing of extraction solvent, and easy leakage during operation, which may affect the extraction effect and detection accuracy. SUMMARY

[0003] The utility model aims at providing a kind of extraction device for cosmetic detection pretreatment to solve the problems raised in the above background.

[0004] To achieve the above object, the utility model provides the following technical scheme: a kind of extraction device for cosmetic detection pretreatment, including base and separatory funnel, the top surface one end of the base is equipped with separatory funnel, the top surface other end of base is fixed with riser, the side of riser is connected with buffer, one end of buffer is connected with first flat plate, the side of first flat plate is equipped with motorized turntable in middle, the surface of motorized turntable is connected with second flat plate.

[0005] When using the extraction device for pretreatment of cosmetics in this technical solution, the operator first needs to connect an external power supply to the device, and then control its operation through the control panel. The operator removes the upper piston from the top opening of the separatory funnel, pours the solvent containing the dissolved cosmetic sample into the top opening, and then pours in an extraction solvent incompatible with the sample solution. After pouring, the operator reinserts the upper piston into the top opening to seal the funnel. Once the solvent is poured in, the operator places the separatory funnel between two clamping frames. After placement, the operator controls the electric slide rail to move the two clamping frames in opposite directions, shortening the distance between them and clamping and fixing the separatory funnel. After the separatory funnel is clamped and fixed, the operator controls the electric turntable to rotate the second plate, which in turn moves the electric slide rail. The separatory funnel, clamped and fixed by the clamping frame, is rotated together to tilt it. After tilting, the operator opens the lower stopcock to release air and starts the vibration motor to shake and agitate it, allowing the solvent inside to be extracted. Once the solvent has separated into layers, the operator stops the vibration motor and closes the lower stopcock. Then, the operator controls the electric turntable to rotate the second plate to return the separatory funnel to a vertical position. After the separatory funnel is upright, the operator places two containers under the separatory funnel. After placement, the lower stopcock is opened to drain the lower layer of liquid from the separatory funnel into the container through the lower opening. After the lower layer of liquid has been drained, the operator closes the lower stopcock, removes the container containing the lower layer of liquid from the bottom of the lower opening, places another container under its lower opening, and then opens the lower stopcock to drain the upper layer of liquid from the container, completing the extraction operation for the cosmetic.

[0006] Preferably, the separatory funnel has a container at its outer bottom, and the container is placed on the top surface of the base. By providing the container, the liquids that have separated into layers inside the separatory funnel can be transferred to their respective interiors, thus providing a temporary storage location.

[0007] Preferably, the separatory funnel has an internal body with an upper opening at the top and an upper piston inside the upper opening. The upper opening and upper piston work together to allow the solvent from the dissolved cosmetic sample and the extraction solvent, which is incompatible with the sample solution, to be poured into the funnel, thus providing a liquid inlet.

[0008] Preferably, the bottom of the hopper is provided with a lower opening, and a lower piston is provided inside the lower opening. Through the cooperation of the lower opening and the lower piston, the extracted and stratified liquid in the hopper can be discharged through this opening, thus providing a drainage point.

[0009] Preferably, one side of the second flat plate is fixed with an electric sliding rail in the middle, and a clamping frame is slidingly installed on the surface of the electric sliding rail. Through cooperation of the electric sliding rail and the clamping frame, different sizes of the separation funnel can be clamped and fixed after being placed between the electric sliding rail and the clamping frame, so that the effect of adaptive clamping is achieved.

[0010] Preferably, the inner surface of the clamping frame is provided with a protective layer, and the protective layer is made of rubber material. The protective layer made of rubber material buffers the contact position of the separation funnel after the clamping frame clamps the separation funnel, so as to avoid damage caused by direct contact.

[0011] Preferably, the other side of the first flat plate is connected with a vibration motor in the middle. Through the vibration motor, the separation funnel can be vibrated to mix the solvents, so that the effect of generating vibration power is achieved.

[0012] Compared with the prior art, the utility model has the beneficial effects that:

[0013] 1. The utility model utilizes the clamping frame which can move oppositely to clamp and fix the separation funnels of different sizes, ensures stability and applicability of the separation funnel in the use process, and the clamped separation funnel can be placed by being rotated and inclined through the electric turntable. The inclined placement not only helps the two solvents in the separation funnel to better blend and stratify, but also facilitates the staff to operate the lower piston to exhaust, without causing liquid leakage. In addition, the inclined separation funnel is vibrated and shaken by the vibration motor in cooperation with the buffer, the uniformity of the solvent mixing is further improved through moderate vibration and shaking, so that the extraction effect is optimized.
