Description

Technical Field

[0001] This utility model belongs to the field of oil detection technology, specifically relating to an edible oil detection device. Background Technology

[0002] There are many methods for testing oils and fats, one of which is chemical titration. The principle is as follows: the prepared oil and fat sample is dissolved in a chloroform-glacial acetic acid solution. The resulting peroxide reacts with potassium iodide to produce iodine. The precipitated iodine is then titrated with a sodium thiosulfate standard solution. The peroxide value is expressed as the mass fraction of iodine equivalent to the peroxide. The specific testing process is as follows: first, a sample is taken; then, the sample is dissolved in chloroform-glacial acetic acid; next, a saturated potassium iodide solution is added, and the mixture is allowed to stand in the dark for 3 minutes. Then, water is added, and the solution is titrated with a sodium thiosulfate standard solution until a pale yellow color is reached. Starch indicator is then added, and titration continues until the blue color disappears. Finally, the peroxide value is calculated. In the above operation process, when dissolving the sample using chloroform-glacial acetic acid (reagent), the two need to be shaken after mixing to make the reaction more uniform and faster. During this process, the reaction container needs to be sealed to prevent reagents and samples from splashing out. Furthermore, when adding saturated potassium iodide solution (reagent), water, sodium thiosulfate standard solution (reagent), and starch indicator (reagent), the seal of the reaction container needs to be repeatedly opened and closed. This not only increases the workload of the operators, but also causes air to enter the reaction container during the repeated opening and closing process. The oxygen in the air reacts with the oil and fat, which will interfere with the test results and lead to inaccurate test results. Summary of the Invention

[0003] Based on this, this application provides an edible oil detection device to solve the technical problem in the prior art where repeatedly opening and closing the reaction vessel during the detection process causes oxygen in the air to enter and interfere with the detection results.

[0004] The technical solution to the above-mentioned technical problems in this application is as follows: An edible oil detection device, comprising: Test tubes are used to hold samples and reagents for reaction. A sealing assembly, connected to the mouth of the test tube, is used to isolate the sample and reagents inside the test tube from the outside environment; Support components are used to mount the operating platform; A circulation component is disposed on the support component and rotates horizontally along a virtual axis. Several test tubes are disposed on the circulation component. A lifting assembly, wherein the lifting assembly is disposed on the support assembly; A dripping component is provided on the lifting component, and the lifting component can drive the dripping component through the sealing component to drip reagent into the test tube.

[0006] Preferably, the lifting assembly is provided with an oscillating part, which can drive the clamping part to vibrate, so that the sample and reagent in the test tube are fully mixed.

The tube plug has an exhaust hole, and a baffle that can block the exhaust hole is provided at the upper opening of the exhaust hole. The lower end of the baffle is connected to the tube plug by a tension spring. The dripping assembly can pass through the slit in the middle of the rubber column and enter the test tube.

[0008] Preferably, the support assembly includes a base and a motor disposed at the bottom of the base. The output shaft of the motor is provided with a gear. The circulation assembly is rotatably connected to the base and is capable of rotating along the axis of the base.

[0009] Preferably, the circulation assembly includes a rotating ring and a toothed ring disposed at the lower end of the rotating ring, the toothed ring meshing with the gear for transmission, and a plurality of the clamping parts disposed on the rotating ring.

[0010] Preferably, the lifting assembly includes a base plate disposed on the base and a telescopic rod disposed on the base plate, the movable end of the telescopic rod being provided with a crossbeam, and the dripping assembly being disposed on the crossbeam.

[0014] Compared with the prior art, this application has at least the following advantages: This application provides an edible oil testing device. A circulation component is mounted on a support component. Samples are added to several test tubes, and several sealing components are used to seal the openings of the test tubes. The circulation component rotates, causing the test tubes to move gradually. A lifting component moves a dispensing component above the test tubes. As the circulation component rotates and one test tube passes below the dispensing component, the circulation gradually stops. The lifting component then lowers the dispensing component, allowing it to pass through the sealing components and enter the test tube to add the required reagent to the sample for mixing. After addition, the lifting component raises the dispensing component back to its original position, and the circulation component continues to rotate, moving another test tube to below the dispensing component. This method ensures automatic reagent addition while maintaining the sample and reagents inside the test tubes isolated from the outside environment, preventing external air from entering and affecting the test results. It also eliminates the need for repeated manual sealing and opening of the test tubes, reducing workload and improving the accuracy of the test data by preventing air interference.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] Please refer to Figures 1 to 11 In one specific embodiment of this application, An edible oil detection device, comprising: Test tube 101 is used to hold samples and reagents for reaction; A sealing assembly is connected to the opening of the test tube 101 to isolate the sample and reagents inside the test tube 101 from the outside environment. Support components are used to mount the operating platform; A circulation component is disposed on the support component and rotates horizontally along a virtual axis. A plurality of test tubes 101 are disposed on the circulation component. A lifting assembly, wherein the lifting assembly is disposed on the support assembly; A dripping component is provided on the lifting component, and the lifting component can drive the dripping component through the sealing component to drip reagent into the test tube 101.

[0021] The sealing component can be a rubber stopper or other elastic sealing device; the support component can be a bracket; the circulation component can be a disc or a rack for supporting test tube 101; the lifting component can be an electric push rod or a threaded screw; and the dripping component can be a liquid phase proportioning valve or a suction pump with a syringe at the output end.

[0022] In the specific operation, the circulation component is mounted on the support component. Samples are then added to several test tubes 101. After sample addition, several sealing components are used to seal the openings of the test tubes 101, achieving a sealing process. The circulation component can then be rotated manually or by a geared motor, gradually moving the test tubes 101. During this process, the lifting component moves the dripping component above the test tubes 101. As the circulation component rotates and one test tube 101 passes below the dripping component, the circulation gradually stops. When the rotation stops, the test tube 101 below the dropping component stops moving and aligns vertically with the dropping component. Then, the lifting component lowers the dropping component, allowing it to pass through the sealing component and enter the test tube 101. The required reagent is then added to the sample for mixing. After the addition is complete, the lifting component raises the dropping component back to its original position, and the circulation component continues to rotate, moving another test tube 101 on the circulation component to the bottom of the dropping component. The above operation is repeated, and the rotation of the circulation component allows several test tubes 101 to pass through the dropping component in sequence, completing the addition of reagents. By using the above method, the sample and reagent inside the test tube 101 can be kept isolated from the outside world while the reagent is automatically added. This prevents outside air from entering the test tube 101 and affecting the test results. At the same time, it eliminates the need for manual sealing and opening of the test tube 101 repeatedly, reducing workload, preventing air from interfering with the test results, and improving the accuracy of the test data.

[0023] In actual operation, test tube 101 serves as the reaction vessel for holding samples and reagents. Therefore, after the reaction is completed, when adding samples, and for subsequent cleaning, test tube 101 needs to be removed from the circulation assembly. Thus, test tube 101 and the circulation assembly need to be designed for easy disassembly and reassembly. Therefore, in this application, the circulation component is provided with a plurality of clamping parts, which are used for the installation and removal of the test tube 101.

[0024] The clamping part can be a clamp or other device that can be set on the circulation assembly to clamp the test tube 101. In practical applications, the clamping part set on the circulation assembly will move with the rotation of the circulation assembly. After the operator adds the sample to the test tube 101 and seals the test tube 101 with the sealing assembly, the test tube 101 can be clamped into its clamping part, so that the test tube 101 can be installed on the circulation assembly and move with the rotation of the circulation assembly. After the test is completed, the test tube 101 can be removed from the clamping part for the detection of the reactants. After the test is completed, the test tube 101 is cleaned and disinfected for subsequent use.

[0025] When adding reagents to test tube 101 to mix with the sample, test tube 101 is shaken to improve mixing and reaction efficiency. The resulting vibrations accelerate the reaction. However, manual operation requires repeatedly removing test tube 101 from the clamp, which is time-consuming and laborious. Therefore, in this application, the lifting assembly is provided with an oscillating part, which can drive the clamping part to vibrate, so that the sample and reagent in the test tube 101 are fully mixed.

[0026] The oscillation unit can be a vibration motor or a device capable of generating vibration. That is, during operation, after the reagent is added to the test tube 101, as the circulation component rotates, the clamping part holding the test tube 101 comes into contact with the oscillation unit. The oscillation unit then transmits the generated vibration to the clamping part, causing the test tube 101 on the clamping part to vibrate. This causes the sample and reagent inside the test tube 101 to oscillate, accelerating the mixing and reaction rate and improving the reaction effect.

[0027] Specifically, an embodiment of the sealing assembly in the above process is provided: The sealing assembly includes a tube plug 102 that can be embedded into the opening of the test tube 101, and a rubber column 103 with a slit in the middle. The tube plug 102 has a vent hole 104, and a baffle 105 that can block the vent hole 104 is provided at the upper opening of the vent hole 104. The lower end of the baffle 105 is connected to the tube plug 102 by a tension spring. The dripping assembly can pass through the slit in the middle of the rubber column 103 and enter the test tube 101.

[0028] The stopper 102 is made of an elastic material. When inserted into the mouth of the test tube 101, the pressure from the inner wall of the test tube 101 causes the stopper 102 to undergo elastic deformation, thus sealing it tightly at the mouth of the test tube 101. Since the amount of elastic deformation of the stopper 102 is generally small, the vent hole 104 on the stopper 102 will not close due to elastic deformation. After the sample is poured into the test tube, the stopper 102 is inserted into the mouth of the test tube 101. At this time, because the stopper 102 is compressed, it causes the rubber column 103 to also undergo elastic deformation. This compression closes the gap in the middle of the rubber column 103, allowing the sample to pass through the gap in the middle of the rubber column 103 into the test tube 101 via the dripping assembly. Here, the dripping assembly is exemplified by a liquid phase proportioning valve, as mentioned above. The dripping assembly is a liquid phase proportioning valve with a syringe at the output end (mentioned below). When the liquid phase valve 601 is moved, the syringe (syringe 602 mentioned below) is inserted into the gap in the middle of the rubber column 103. The syringe opens the gap and enters the test tube 101. Then the liquid phase proportional valve injects the reagent connected through the pipeline into the syringe, so that the reagent enters the test tube 101 and mixes with the sample. Because the test tube 101 is sealed by the tube plug 102, the internal pressure of the test tube 101 will increase when the reagent enters. At this time, the air inside the test tube 101 will push the baffle 105 upward through the vent hole 104, so that the baffle 105 no longer blocks the vent hole 104. At this time, the tension spring is stretched, which can expel the air inside the test tube 101 to the outside, so that the pressure inside the test tube 101 is consistent with the external pressure, and the tube plug 102 will not be dislodged from the opening of the test tube 101 when the reagent is injected because the internal pressure cannot be discharged. By means of the above method, after the sample is added to the test tube 101, the test tube can be sealed with the tube stopper 102. In subsequent reagent addition processes, it is not necessary to remove the tube stopper 102 from the opening of the test tube 101, thereby eliminating the need to repeatedly open and close the opening of the test tube 101 and preventing oxygen in the air from entering and causing oxidation of the oil, which would interfere with the test results.

[0029] Specifically, an embodiment of the supporting components in the above process is provided: The support assembly includes a base 401 and a motor 402 disposed at the bottom of the base 401. A gear 403 is disposed on the output shaft of the motor 402. The circulation assembly is rotatably connected to the base 401 and can rotate along the axis of the base 401.

[0030] The base 401 can be mounted on an operating platform, such as a laboratory bench or desktop. The circulation component is rotatably connected to the base 401. The operator can manually rotate the circulation component to allow several test tubes 101 to pass under the dropping component in sequence for reagent addition. To reduce manual intervention and workload, a toothed ring (toothed ring 303) can be installed on the circulation component. The teeth mesh with the gear 403, and under the drive of the motor 402, the gear 403 rotates, causing the ring to rotate, which in turn drives the circulation component to rotate, achieving an automatic rotation process. Furthermore, the motor 402 can be used to control the circulation component to move the test tubes 101 to a stop under the dropping component during rotation, so that the dropping component can add reagents to the test tubes 101, replacing manual labor and eliminating the need for human intervention, thus improving the degree of automation.

[0031] Additionally, a light shield 404 is provided on the base 401, which allows the test tube 101 to enter the light shield 404 for light protection when the circulation assembly moves, thereby preventing light from affecting the reagents and samples and interfering with the test results. At the same time, an inwardly extending ring is detachably connected to the lower end of the light shield 404. The ring can support the weight of the circulation assembly (the rotating ring 301 mentioned below), allowing the circulation assembly to rotate stably around the base 401. Furthermore, a planar bearing can be provided between the circulation assembly and the ring to reduce friction between them and make the rotation smoother.

[0032] Specifically, an embodiment is provided for the loop component in the above process: The circulation assembly includes a rotating ring 301 and a toothed ring 303 disposed at the lower end of the rotating ring 301. The toothed ring 303 meshes with the gear 403 for transmission, and a plurality of the clamping parts are disposed on the rotating ring 301.

[0033] The swivel ring 301 is rotatably connected to the base 401. This connection can be achieved through bearings, such as tapered roller bearings, which can withstand axial and radial forces. Specifically, the inner ring of the bearing is connected to the base 401, and the outer ring is connected to the swivel ring 301. Driven by the motor 402, the gear 403 meshes with the gear ring 303, causing the gear ring 303 to drive the swivel ring 301 to rotate on the base 401. The swivel ring 301 rotates around the axis of the base 401 (the virtual axis mentioned above), thus allowing the swivel ring 301 to rotate... When the motor moves several clamping parts, the test tubes 101 clamped in the clamping parts rotate around the axis of the base 401. When one of the test tubes 101 moves under the dropping component, the motor 402 stops. At this time, the lifting component can drive the dropping component to descend and add the reagent to the test tube 101. Then the lifting component drives the dropping component to rise and reset. When the motor 402 is restarted, the rotating ring 301 can rotate again, so that the other test tube 101 moves under the dropping component for reagent addition.

[0034] Specifically, an embodiment is provided for the loop component in the above process: The lifting assembly includes a base plate 501 disposed on the base 401, and a telescopic rod 504 disposed on the base plate 501. A crossbeam 505 is disposed at the movable end of the telescopic rod 504, and the dripping assembly is disposed on the crossbeam 505.

[0035] The telescopic rod 504 can be an electric telescopic rod or a cylinder, etc. In the initial state, the telescopic rod 504 drives the crossbeam 505 to be in the raised state, so that the crossbeam 505 drives the dripping component to rise above the circulation component and the test tube 101, so as not to interfere with the normal rotation of the rotating ring 301. When the rotating ring 301 rotates and drives the test tube 101 to move below the dripping component, the rotating ring 301 stops rotating, so that the test tube 101 is aligned with the dripping component. Then the telescopic rod 504 can drive the crossbeam 505 to descend, so that the crossbeam 505 drives the dripping component to descend through the tube stopper 102 and enter the test tube 101 to complete the injection of reagent. After the injection is completed, the telescopic rod 504 drives the crossbeam 505 to rise and reset, so that the dripping component leaves the tube stopper 102. Then the rotating ring 301 continues to rotate, so that the next test tube 101 moves to the bottom of the dripping component and stops, and continues to add reagent to the next test tube 101.

[0036] Specifically, an embodiment is provided for the loop component in the above process: The dripping assembly includes a liquid phase valve 601 disposed on the crossbeam 505 and a needle tube 602 disposed at the output end of the liquid phase valve 601. The needle tube 602 can pass through the gap in the middle of the rubber column 103 and enter the test tube 101. The lower end of the liquid phase valve 601 is connected to a pressure plate 603 through a slide rod 604. A spring is disposed between the pressure plate 603 and the lower part of the liquid phase valve 601.

[0037] As the crossbeam 505 descends, it can drive the liquid phase valve 601 to descend as well. This causes the syringe 602 on the lower output end of the liquid phase valve 601 to descend as well. When the syringe 602 descends, it can be aligned with the test tube 101 that is resting below, allowing the syringe 602 to penetrate the gap in the middle of the rubber column 103 and squeeze through the gap into the test tube 101. This allows the liquid phase valve 601 to inject the reagent delivered through the pipeline into the test tube 101 through the syringe 602. After injection, when the liquid phase valve 601 returns to its original position as the crossbeam 505 rises, the friction between the syringe 602 and the rubber column 103 is relatively high because the syringe 602 is inserted into the gap in the middle of the rubber column 103. This poses a risk that the rising syringe 602 could pull out the rubber column 103 and the tube plug 102 from the test tube 101. Therefore, when the crossbeam 505 lowers the liquid phase valve 601, the pressure plate 603 first contacts the tube plug 102, holding it in place. As the liquid phase valve 601 continues to descend, the slide rod 604 slides relative to the liquid phase valve 601, at which point the spring is compressed. During the process of injection, the syringe 602 is inserted into the gap in the middle of the rubber column 103 to inject the reagent. After the injection is completed, when the liquid phase valve 601 rises and resets, causing the syringe 602 to rise, the spring will rebound from the compressed state. At this time, the spring will press the pressure plate 603, so that the pressure plate 603 will always press on the tube plug 102. When the syringe 602 is pulled out of the rubber column 103, the tube plug 102 is prevented from being pulled out of the test tube 101. After the syringe 602 is completely pulled out of the rubber column 103, as the liquid phase valve 601 continues to rise, the spring rebounds to the normal state, and the slide rod 604 drives the pressure plate 603 to leave the tube plug 102. By means of the above method, the stopper 102 can be stably sealed to the test tube 101 when adding reagents, and after the addition is completed, the syringe 602 is prevented from pulling out the stopper 102 and the stopper 102 is prevented from detaching from the mouth of the test tube 101.

[0038] Specifically, an embodiment of the clamping part in the above process is provided: The clamping part includes a clamp 201 disposed on the rotating ring 301 and a pad 202 disposed at the lower end of the clamp 201. The test tube 101 can be clamped in the clamp 201. The clamp 201 is provided with a spherical protrusion 204. The oscillating part can contact the spherical protrusion 204 to generate vibration.

[0039] After the sample is loaded into the test tube 101, the test tube 101 is clipped into the clamp 201, and the bottom of the test tube 101 is placed on the pad 202, thus completing the clamping of the test tube 101. When the rotating ring 301 rotates, the spherical protrusion 204 passes through the oscillating part and makes contact, causing the spherical protrusion 204 to vibrate and transmit the vibration to the clamp 201 and the test tube 101, thereby oscillating the sample and reagent in the test tube 101, accelerating the reaction effect and efficiency of the reagent and sample, and making the two mix more evenly.

[0040] Specifically, an embodiment of the oscillation section in the above process is provided: The oscillating part includes a fan-shaped plate 502 with a wave-like structure on the outside, and the outside of the fan-shaped plate 502 can contact the spherical protrusion 204.

[0041] The sector plate 502 is connected to the side of the base plate 501, and the bottom of the clamp 201 is provided with a rubber pad 203. The upper end face of the rotating ring 301 is provided with a slot 302, and the bottom of the clamp 201 can be embedded in the slot 302. The rubber pad 203 fills the gap between the bottom of the clamp 201 and the slot 302. When the rotating ring 301 rotates, the rotating ring 301 drives the clamp 201 to move past the sector plate 502. When the spherical protrusion 204 on the clamp 201 passes through the sector plate 502, it will contact the wave-shaped structure on the side of the sector plate 502. By utilizing the crests and troughs of the wave-shaped structure, the spherical protrusion 204 will be displaced in the horizontal direction when it contacts the sector plate 502, causing the spherical protrusion 204 to drive the clamp 201 to move. The elastic deformation of the rubber pad 203 can satisfy the slight sway of the clamp 201 in the horizontal direction, thereby causing the clamp 201 to drive the test tube 101 to sway and form an oscillation effect.

[0042] Here, an implementation procedure for the above process is provided: The first step is to load the sample into several test tubes 101, insert a tube stopper 102 into the opening of each test tube 101, and then clip the test tubes 101 into several clamps 201 respectively. The second step is to turn on the motor 402, so that when the gear 403 rotates, it meshes and drives the rotating ring 301 to rotate. When the rotating ring 301 rotates, it drives several clamps 201 to move, so that several test tubes 101 pass under the syringe 602 in sequence. Thirdly, when one of the test tubes 101 moves below the syringe 602, the motor 402 stops, causing the test tube 101 to remain below the syringe 602. Figure 1 and Figure 2Taking the content as an example, the motor 402 drives the gear 403 to rotate counterclockwise, the rotating ring 301 rotates counterclockwise, and the front of the light shield 404 opens. Taking the left telescopic rod 504 as a reference, the test tube 101 below the left telescopic rod 504 is the first test tube. The left telescopic rod 504 can be used to drive the crossbeam 505 to descend, so that the syringe 602 descends into the middle gap of the rubber column 103 and enters the test tube 101, injecting chloroform-glacial acetic acid into the test tube 101. Then, it is reset, and the rotating ring 301 continues to rotate, so that the test tube on the left side of the test tube 101... 101 moves to below syringe 602, while the first test tube 101 moves to the right. A window period is reserved between the left telescopic rod 504 and the right telescopic rod 504 for the test tube to move (that is, after adding chloroform-glacial acetic acid to test tube 101, no other operation is performed during this process, allowing time for the chloroform-glacial acetic acid to react with the sample). During this process, the spherical protrusion 204 will vibrate as it passes the side of the fan-shaped plate 502, thereby agitating the sample and chloroform-glacial acetic acid after mixing, making the two more evenly mixed. Until the first test tube moves to below the right crossbeam 505, the right telescopic rod 504 drives the crossbeam 505 to descend, causing the syringe 602 to descend into the middle gap of the rubber column 103 and enter the test tube 101, adding the saturated potassium iodide solution into the test tube 101, and then resetting after addition; then the rotating ring 301 continues to rotate, and the spherical protrusion 204 will still contact the side of the fan-shaped plate 502 to achieve oscillation mixing of the saturated potassium iodide solution and the sample; In the fourth step, test tube 101 will enter the light shield 404 from the right side. When test tube 101 enters the light shield 404, the spherical protrusion 204 will no longer continue to contact the side of the sector plate 502, and test tube 101 will be in a static state, so that the sample after adding saturated potassium iodide solution is protected from light. The rotation speed of motor 402 can be controlled so that the time for the rotating ring 301 to drive the same test tube 101 from the right side of the light shield 404 to the left side of the light shield 404 is controlled within a range of at least three minutes, so as to provide sufficient time for the sample to react with saturated potassium iodide solution. Fifth, repeat the above operation until all the test tubes 101 on the rotating ring 301 have completed the above steps, and when the first test tube 101 is removed from the left side of the light shield 404, the subsequent reagents (water, sodium thiosulfate standard solution, starch indicator) can be added, thereby realizing the detection process of several test tubes 101 rotating in a cycle. After all the reagents have been added, all test tubes 101 can be removed from the open part of the front of the light shield 404 while the rotating ring 301 is rotating, and then the generated reactants are detected to obtain the final detection results.

[0043] Through the above operation process, only the sample needs to be added to the test tube 101 manually and the tube stopper 102 needs to be plugged. The subsequent addition of reagents and the rotation of the rotating ring 301 can be controlled by a computer or program to realize an intelligent and automated detection process.

[0044] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
