[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0021] This embodiment describes a sample preparation device for rapid testing of edible agricultural products, which relates to the field of agricultural product quality and safety testing technology. Through the cooperation of the bottle body 100, the detachable crushing component 200 and the integrated filter component 300, the upper clear liquid can be directly filtered after the agricultural product is crushed, avoiding the problem of secondary processing required by traditional equipment. It has the advantages of reducing operation steps, preventing pollution and improving testing efficiency.

[0022] Please see Figures 1 to 7 This embodiment of a sample preparation device for rapid detection of edible agricultural products includes: a bottle 100 for holding agricultural products and extracts, a crushing component 200, and a filtering component 300. The crushing component 200 is detachably connected to one end of the bottle 100, which can crush and fully mix the agricultural product extracts to extract the substances to be detected located on the agricultural products.

[0023] The filter assembly 300 includes a cover 310, a filter tube 320, and a filter unit 330. The filter tube 320 is integrally connected to the cover 310. One end of the filter tube 320 extends relative to the bottle body 100, forming an extension 321 away from the cover 310. The filter unit 330 is disposed at the end of the extension 321. The filter unit 330 can be immersed in the upper clear liquid, away from solid impurities in the mixed liquid, effectively avoiding the direct impact of broken solid products on the filter medium and reducing the frequency of filter media clogging.

[0024] By directly mounting the filter assembly 300 onto the cover 310, the clear liquid filtration process can be completed in a single operation without transferring the container, thus significantly improving the continuity of the sample preparation process and shortening the sample preparation time.

[0025] The crushing component 200 and the cap 310 are detachably connected to the bottle body 100, which can directly expose the inner cavity of the bottle body 100, the working area of ​​the crushing component 200 and the cap 310, making it convenient for on-site testing personnel to clean the filter residue and clean the utensils, thereby facilitating repeated testing and avoiding cross-contamination between different test samples, which may interfere with the sampling results.

[0026] The filter unit 330 is located at one end of the filter tube 320. It is small in size and light in weight, which facilitates replacement after filtration and helps to save the amount of material used in the 320 filter unit, thus reducing costs.

[0027] During operation, the agricultural product sample and extract are placed into bottle 100, which is then upright. The mixture is broken down and mixed using the agitator 200. The bottle 100 is then inverted and allowed to stand until the mixture separates into layers. The clear upper layer containing the target components flows into the filter tube 320 through the tilted bottle 100. Because the end of the tube extension is submerged in the clear liquid layer, the filter unit 330 performs filtration away from the sediment at the bottom of the bottle, preventing direct contact between the fibrous material and the filter media. The filtered liquid is discharged through the internal channel of the tube, while the solid residue remains at the bottom of bottle 100.

[0028] In some embodiments, please refer to Figure 4 and Figure 5 The end of the extension 321 protrudes relative to the end of the cap 310, and the length of the extension 321 does not exceed half the length of the bottle body 100. By limiting the length of the filter tube 320, the filter unit 330 located at the end of the extension 321 can pass over the sediment in the mixed liquid and enter the clear liquid, avoiding direct contact between the filter unit 330 and the sediment. This effectively avoids direct impact of broken solid products on the filter medium and reduces the frequency of filter media clogging. The length of the extension 321 is controlled to be within half the total height of the bottle body 100, ensuring sufficient filtration stroke while avoiding instability of the equipment's center of gravity due to excessive length.

[0029] In the specific implementation process, the fact that the end of the extension 321 protrudes from the end of the cover 310 means that the extended end of the filter tube 320 extends beyond the edge of the cover 310, and the side projection of the filter tube 320 relative to the cover 310 is outside the cover 310, so that the end of the filter tube 320 can be separated from the cover 310 which has precipitated solid impurities.

[0030] The statement that the length of the extension 321 does not exceed 1 / 2 of the length of the bottle body 100 means that the longitudinal dimension of the extension of the filter tube 320 is limited to half the total height of the container, and the length limitation of the filter tube 320 ensures that the filtration path matches the container capacity.

[0031] After the bottle 100 is filled with the mixture, the extension 321 extends to an appropriate depth below the liquid surface, and its end protrudes from the cap 310, ensuring that the filter unit 330 is always in the working area above the liquid surface. The length of the extension 321 is controlled to be less than half the total height of the bottle 100. During the filtration process, as the mixture flows through the internal channels of the extension 321 to the filter unit 330, the limited length parameter optimizes the liquid flow path, allowing solid impurities to settle and separate within a reasonable travel distance.

[0032] In some embodiments, please refer to Figure 5 and Figure 6The filter unit 330 includes a filter element 331, which can block the end of the extension 321. By integrating the filter element 331 at the end of the extension 321, a single-point filtration structure is formed. The filtration action is automatically triggered when the bottle 100 is inverted, avoiding the steps of repeatedly disassembling and assembling the filter assembly 300 in traditional equipment. At the same time, manual replacement of the filter element 331 is more convenient, and multiple tests can be performed on different agricultural products as needed, thus improving the applicability of the equipment.

[0033] In practical implementation, the filter element 331 is a component used to filter solid impurities. It can be implemented using filter cotton or filter cloth, which traps solid particles through the gaps between the fibers. The filter element 331 is located at the end of the extension 321 and can directly contact the liquid to be filtered to achieve solid-liquid separation.

[0034] Specifically, when the agitated mixture inside the bottle 100 needs to be filtered, the bottle 100 is inverted to allow the liquid to flow into the extension section 321. After the filter element 331 blocks the end of the extension section 321, the liquid penetrates the filter element 331 under the action of gravity, and solid impurities are trapped in the extension section 321 and inside the bottle 100. Since the filter element 331 directly covers the end of the liquid outflow path, the filtration process does not require additional liquid transfer or replacement of the filter device, simplifying the operation.

[0035] In further implementation, the filter unit 330 also includes a fastener 332, which is sleeved on the end of the extension 321. The filter element 331 is disposed between the fastener 332 and the extension 321, and the fastener 332 can constrain the filter element 331 to the end of the extension 321. The detachable fastener 332 structure ensures a stable and sealed filtration interface while enabling rapid maintenance and replacement of the filter element 331, effectively solving the problem of decreased filtration efficiency over time. The fastener 332 provides reliable fixation and convenient maintenance of the filter medium, preventing liquid leakage or impurity penetration caused by displacement of the filter element 331, significantly improving the continuity of the sample preparation process and the accuracy of the test results, while reducing equipment maintenance costs.

[0036] In practical implementation, fastener 332 is a ring-shaped constraint structure used to fix filter element 331. It can be implemented by threaded connection or snap-locking method, pressing filter element 331 against the end face of extension 321 through mechanical constraint force. Fastener 332 can prevent filter element 331 from shifting under liquid impact and ensure that the filtration interface completely covers the flow channel.

[0037] After the filter element 331 is installed at the end of the extension 321, the fastener 332 wraps around the outer wall of the extension 321 through a sleeve connection, forming an axial constraint on the filter element 331. When the bottle 100 is inverted, the mixture flows through the extension 321 to the filter element 331, solid impurities are trapped on the surface of the filter element 331, and the filtered clear liquid passes through the pores to enter the detection stage. The fastener 332 and the extension 321 are detachably connected, allowing for quick separation and replacement of the component when the filter element 331 becomes clogged.

[0038] In some embodiments, please refer to Figure 7 A sealing cap 311 is provided at the end of the cap 310 away from the bottle body 100. One end of the sealing cap 311 is hinged to the cap 310, and the other end of the sealing cap 311 is sealed to the filter tube 320. The hinged sealing cap 311 enables the filter tube 320 to be opened and closed quickly, and the opening and closing timing of the filter tube 320 can be controlled as needed to optimize the filtration process.

[0039] In practical implementation, the sealing cap 311 is a movable component used to seal the end of the filter tube 320. It can be made of plastic or metal and its opening and closing function is achieved through a hinge. The hinge connects the two components via a pivot or hinge structure, allowing the sealing cap 311 to rotate around a fixed axis. When the bottle 100 is inverted and the mixture is waiting to separate into layers, the sealing cap 311 seals the filter tube 320, forming a relatively closed space in the filter tube 320, which can prevent the filtrate from passing through.

[0040] When it is necessary to filter the mixture, the sealing cap 311 rotates open around the hinge point, exposing the extension 321 of the filter tube 320. At this time, solid impurities are intercepted by the filter unit 330, and the clear liquid flows out through the filter tube 320.

[0041] It should be noted that the other end of the sealing cap 311 is provided with a sealing plug 311a, which is movably inserted into the filter tube 320. The sealing plug 311a can quickly open and close the filter tube 320. The sealing plug 311a is a rubber plug, which has good resistance to deformation and can form a good seal for the filter tube 320.

[0042] In some embodiments, the blending assembly 200 includes a base 210 and a rotatable blending blade 220. The base 210 is detachably connected to one end of the bottle 100, and the blending blade 220 is disposed in the bottle 100 and rotatably connected to the base 210. The base 210 can be disassembled from the bottle 100, thereby exposing the inner cavity of the bottle 100 and the blending blade 220, which facilitates cleaning of the blending blade 220 and the bottle 100.

[0043] The base 210 is a support structure used to support the crushing blade 220 and connect it to the bottle body 100. Specifically, it can be implemented using a ring base with a threaded interface, which provides a stable mounting base for the crushing blade 220. The crushing blade 220 is a blade used to crush agricultural products, which can be implemented using a rotating blade made of stainless steel. Its function is to crush materials through rotational cutting.

[0044] During the sample preparation process, the drive unit 230 drives the crushing blade 220 to rotate at high speed, crushing and mixing the agricultural products in the bottle 100. After the operation is completed, the drive unit 230 can be separated from the base 210 for easy cleaning or replacement of parts.

[0045] The pulverizing assembly 200 also includes a drive unit 230. The base 210 is detachably connected to the drive unit 230, so that the base 210 can be separated from the drive unit 230. When the bottle 100 is upright or inverted, there is no need to operate the heavy drive unit 230, which simplifies the workflow and reduces the difficulty of operation.

[0046] The end of the pulverizing blade 220 is rotatably connected to the drive unit 230, which can drive the pulverizing blade 220 to rotate relative to the base 210. The detachable connection design allows the drive unit 230 to be maintained independently, improving the stability of the equipment operation.

[0047] In practical implementation, the drive unit 230 is a device used to provide rotational power, which can be implemented using an electric motor or a hydraulic motor. Its output shaft is connected to the crushing blade 220 through a transmission structure, thereby enabling the crushing blade 220 to crush agricultural products. The base 210 and the drive unit 230 are fixed in a separable manner, which can be achieved through threaded engagement or a snap-fit ​​structure, facilitating independent maintenance or replacement of the drive unit 230. The rotatable connection is achieved by transmitting torque between the crushing blade 220 and the drive unit 230 through moving parts, which can be implemented using a coupling or bearing structure, ensuring that the crushing blade 220 rotates stably under the drive of the drive unit 230.

[0048] When the drive unit 230 is activated, the crushing blade 220 rotates at high speed within the bottle 100, crushing the agricultural products and mixing them with the extract. The base 210 is fixed to the drive unit 230 via a threaded connection. When cleaning or replacing the drive unit 230, it can be unscrewed from the base 210. The coupling between the crushing blade 220 and the drive unit 230 allows for a certain degree of axial misalignment, thereby preventing transmission failure due to installation errors.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the present utility model.
