[0021] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Example 1

[0024] As mentioned in the background section, this application proposes a fully automated solid-phase extraction alarm device to address the problems in the prior art. Please refer to [link / reference]. Figure 1 As shown, it includes:

[0025] The housing 11 has a first space inside, and a plurality of solvent bottles 21 are arranged sequentially along a first direction in the first space. The solvent bottles 21 are filled with solvent, and a solvent conduit 12 is inserted into the top of the solvent bottle 21. One end of the solvent conduit 12 extends and penetrates to the outside of the first space, and the other end extends to the bottom inside the solvent bottle 21.

[0026] Furthermore, the housing 11 is made of a light-shielding material.

[0027] Specifically, the housing 11 has an internal space, namely the first space, which is shaped like a cuboid and provides housing and protection for the internal components. Its material is light-shielding, preventing external light from entering. Several first spaces arranged sequentially along a first direction (e.g., horizontal) within the housing 11 are cylindrical and used to hold the solvent required for solid-phase extraction. The bottle opening is at the top, and the interior of the bottle is hollow, storing the solvent. The solvent conduit 12 is a slender tubular structure; one end is inserted from the top opening of the solvent bottle 21 to the bottom of the bottle, ensuring that the solvent at the bottom can be extracted; the other end penetrates the outer wall of the first space of the housing 11 and connects to an external solid-phase extraction device for solvent delivery. The solvent bottle 21 is placed inside the housing 11, and the solvent conduit 12 connects the solvent bottle 21 to the outside. This achieves solvent storage and delivery, providing a stable solvent supply for the solid-phase extraction process, while the housing 11 protects the solvent from light and prevents solvent deterioration.

[0028] Specifically, the shell 11 is made of light-shielding materials, such as black plastic or metal-coated plates. The material is dense and opaque, creating a light-free environment for photosensitive solvents, preventing the solvent from decomposing or deteriorating due to light exposure, and ensuring the accuracy of the extraction experiment.

[0029] An alarm mechanism is provided, comprising a sensing component 22 disposed outside each solvent bottle 21. Each sensing component 22 is used to monitor the liquid level change of the solvent in its corresponding solvent bottle 21 in real time, and to trigger an alarm signal indicating that the liquid level in the corresponding solvent bottle 21 is low when the liquid level is lower than a set sensing area.

[0030] In a preferred embodiment, each of the sensing components 22 is electrically connected to a corresponding display component 13, which is disposed on the outer wall of the housing 11 and is used to display the alarm signal with indicator lights of different colors or flashing frequencies.

[0031] Specifically, the display component 13 is an indicator light, located on the outer wall of the housing 11, typically a circular or square light-emitting diode module, connected to the sensing component 22 via a circuit. The sensing component 22 is electrically connected to the corresponding display component 13, and signal transmission enables linkage. This visualizes the liquid level information, allowing operators to intuitively understand the liquid level status of the solvent bottle 21 without opening the housing 11, improving operational convenience and monitoring efficiency. When the sensing component 22 detects a low liquid level signal, it transmits it to the display component 13, causing the indicator light to illuminate with a specific color or flashing frequency.

[0032] In a preferred embodiment, the sensing component 22 is a U-shaped photoelectric liquid level sensor, which is sleeved on the outside of the solvent bottle 21, and the projection area of ​​the U-shaped structure on the solvent bottle 21 is the set sensing area.

[0033] Specifically, the sensing component 22 is a U-shaped photoelectric liquid level sensor. The photoelectric liquid level sensor is independent of other characteristics of the medium, including temperature, pressure, density, and electrical parameters. Therefore, it has accurate liquid level detection, high repeatability, fast response speed, and very precise liquid level control. The U-shaped opening surrounds the solvent bottle 21, and the "U-shaped" area inside is the effective sensing area. A light source device (such as a light-emitting diode) and a light receiving device (such as a photoresistor) are respectively provided at both ends. When the liquid level is higher than the set sensing area, the light emitted by the light source device is refracted into the liquid, and the light receiving device receives a small amount of light or no light. When the liquid level is lower than the set sensing area, the light is directly reflected back to the light receiving device, which triggers an alarm signal.

[0034] In a preferred embodiment, the first space is further provided with a support adjustment component corresponding to each solvent bottle 21. The support adjustment component is used to adjust the relative height between the sensing component 22 and the solvent bottle 21 along a second direction; the second direction is perpendicular to the first direction.

[0035] In a preferred embodiment, the solvent bottle 21 is placed on the bottom plate of the housing 11, and the support adjustment assembly is a sensor support frame 23 disposed on one side of the solvent bottle 21. The sensor support frame 23 is used to support or adjust the height of the sensor assembly 22 along the second direction.

[0036] Specifically, such as Figure 2 As shown, the sensor support frame 23 resembles a three-dimensional structure combining columnar and plate-like features. Its bottom is firmly fixed to the base plate of the housing 11 by welding or screws, ensuring that it will not shift during the operation and movement of the device. Near the solvent bottle 21, it extends a support plate with an adjustment structure, which serves as a support surface for the sensor component 22. The adjustment structure may include a vertical slide rail with a slider mounted on it. The sensor component 22 is fixed to the slider, and by pushing the slider up and down along the slide rail, the height of the sensor component 22 in the second direction (the height direction of the housing 11) can be easily adjusted. Alternatively, a screw adjustment method can be used, with a vertical elongated hole in the support plate through which a screw connects to the sensor component 22. Rotating the screw raises or lowers the sensor component 22.

[0037] When it is necessary to adapt to solvent bottles 21 of different heights, or when there are special requirements for the liquid level detection height according to different solid phase extraction experiments, the operator only needs to operate the adjustment structure of the sensor support frame 23 to quickly and accurately adjust the height position of the sensor component 22, ensuring that the "U-shaped" sensing area of ​​the photoelectric liquid level sensor is in the optimal detection correspondence state with the liquid level in the solvent bottle 21, thereby reliably realizing real-time monitoring of solvent level changes and providing accurate and stable solvent balance early warning guarantee for the fully automated solid phase extraction process.

[0038] At the same time, multiple photoelectric liquid level sensors can be connected in parallel, and multiple preset sensing areas can be set to match different solid phase extraction needs. No complicated algorithms are required; it is only necessary to observe the trigger status of the photoelectric sensors to determine whether liquid needs to be added or other operations.

[0039] In a preferred embodiment, the sensing component 22 is mounted on a support platform at a fixed height, the support platform is mounted on the bottom plate of the housing 11, and the support adjustment component is an adjustment support frame mounted on the bottom of the solvent bottle 21. The adjustment support frame is mounted on the bottom plate of the housing 11 and is used to support or adjust the height of the solvent bottle 21 along the second direction.

[0040] Specifically, the support adjustment assembly is located at the bottom of the solvent bottle 21 and has a frame structure with adjustable feet or shims to change the height of the solvent bottle 21. The adjustable support frame supports the solvent bottle 21, and the solvent bottle 21 and the sensing component 22 are adapted through relative height changes, while the support platform remains stationary. This allows for relative height adjustment between the sensing component 22 and the solvent bottle 21, ensuring accurate liquid level detection and structural stability. By adjusting the support frame to change the height of the solvent bottle 21, the liquid level is matched with the set sensing area of ​​the sensing component 22.

[0041] In a preferred embodiment, the housing 11 includes a bottom plate, the edge of the bottom plate extends along a second direction to form a plurality of interconnected side plates, one of the side plates is hinged to a top plate, the hinge axis is in the first direction, and the top plate is provided with a plurality of through holes for penetrating the solvent conduit 12.

[0042] Specifically, the housing 11 is a cuboid structure consisting of a base plate, four side plates, and a top plate. The base plate is flat, and the side plates extend vertically upwards along the edges of the base plate to form the sides of the cuboid. One side plate is connected to the top plate via a hinge or other hinge structure, with the hinge axis along a first direction. The top plate is also flat and has several circular through holes corresponding to the positions of the solvent conduit 12. The components are connected as a whole by welding, hinges, etc., and the solvent conduit 12 passes through the through holes in the top plate. This housing 11 facilitates the installation and maintenance of internal components such as the solvent bottle 21 and the sensing component 22. The top plate can be opened and closed, improving the openness of the device. When the top plate is opened, the operator can operate inside; when closed, it maintains a sealed and light-proof state.

[0043] In a preferred embodiment, the bottom of the housing 11 is provided with an anti-slip pad.

[0044] Specifically, an anti-slip pad is provided at the bottom. The anti-slip pad is generally made of rubber, is sheet-shaped, and has raised textures or particles on the surface. The anti-slip pad is attached or embedded in the lower surface of the base plate of the housing 11. This increases the friction between the device and the surface on which it is placed, prevents slippage during operation and vibration, and improves stability.

[0045] In a preferred embodiment, the side panel is provided with an observation window made of a dark transparent material.

[0046] Specifically, an observation window is provided on the side panel of the housing 11. The observation window is made of a dark transparent material such as brown acrylic glass, and is square or round in shape. It is embedded in the pre-reserved holes in the side panel and sealed and integrated with the side panel. This allows the operator to view the appearance of the solvent bottle 21 without compromising the light-blocking performance of the housing 11, thus assisting in monitoring. When the indicator light indicates that a solvent bottle 21 has a low liquid level, the top panel of the housing 11 can be left unopened. The solvent bottle 21 can be observed through the observation window first, and after confirming that the liquid level is indeed low, the liquid addition operation can proceed.

[0047] Specifically, this application can improve the automation level of solid-phase extraction, eliminating the need for manual observation of the remaining liquid in solvent bottle 21. It only requires checking the indication of the photoelectric liquid level sensor to determine whether liquid needs to be added. This reduces the risk of solid-phase extraction experiments, as the device can effectively indicate reagent levels, preventing experimental failure due to insufficient reagents. Within the width requirements of the photoelectric liquid level sensor's detection tank, the diameter of solvent bottle 21 can be changed arbitrarily without requiring adjustments to the algorithm or hardware of the device.

[0048] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. The above descriptions are only preferred embodiments of this application. It should be noted that due to the limitations of written expression, while there are objectively infinite specific structures, those skilled in the art can make several improvements, modifications, or changes without departing from the principles of this invention, and can also combine the above technical features in an appropriate manner. These improvements, modifications, changes, or combinations, or the direct application of the inventive concept and technical solution to other situations without modification, should all be considered within the scope of protection of this application.
