Description

Technical Field

[0001] The present invention relates to the technical field of royal jelly detection, in particular to a novel royal jelly freshness rapid detection device. Background Art

[0002] Royal jelly, as a bee product with extremely high nutritional value and wide application fields, plays an important role in the health food, medicine, cosmetics and other industries. It has a complex composition and is rich in various bioactive substances, such as royal jelly protein. These active ingredients directly determine the quality of royal jelly's health functions. However, the freshness of royal jelly has a great influence on the content of its active ingredients. As the freshness decreases, the active ingredients will gradually degrade and be lost. Therefore, it is necessary to use a detection device to detect the freshness of royal jelly.

[0003] Chinese patent publication number CN211528218U discloses a novel rapid detection device for royal jelly freshness. The method determines freshness by mixing royal jelly with a detection reagent and then comparing the mixture with a colorimetric determination device. The method has the advantages of a stable detection environment and rapid display of detection results.

[0004] The above patent document relies on the naked eye to compare the mixture of royal jelly and detection reagent with a variety of colorimetric cards of different colors to determine the freshness. This is greatly affected by human factors and has low accuracy. In addition, after the royal jelly and the detection reagent are mixed, they need to be manually transferred to multiple colorimetric cards, which is inconvenient to operate and has a low transfer rate, which affects the detection efficiency. At the same time, during the manual transfer process, the mixture is exposed to the environment and is easily contaminated by impurities such as dust and microorganisms in the air, which may change its chemical properties and cause deviations in the reaction results with the detection reagent, ultimately affecting the accurate determination of the freshness of the royal jelly.

The controller compares the temperature signal fed back by the temperature sensor 13 with the preset temperature value. When the temperature is detected to be lower than the preset value, the controller will issue an instruction to start the electric heating tube for heating. When the temperature reaches the preset value, the controller will control the electric heating tube to stop heating, thereby realizing automatic adjustment and control of the temperature inside the body 1, so that the detection environment in the body 1 is always maintained at an appropriate temperature. The electric heating tube, the temperature sensor 13 and the controller are all disclosed in the patent with publication number CN202410658U and the patent name is Chemical Reaction Tank with Temperature Sensor. They belong to the prior art and their working principles are not described in detail here.

[0021] An LED linear light source 8 is fixedly installed in the body 1, and the light output end of the LED linear light source 8 corresponds to one side of the detection area 5. The LED linear light source 8 is used to emit light of a specific wavelength to the mixed liquid in the detection area 5. The solution has low light transmittance. A light shield 9 is fixedly installed on the outer surface of the detection area 5 away from the LED linear light source 8. A photosensor 10 is arranged in the light shield 9. A window for the light emitted by the LED linear light source 8 to enter is opened on the side of the light shield 9 that is in contact with the outer surface of the detection area 5. The photosensor 10 is used to receive the light that passes through the mixed liquid and convert it into an electrical signal. For a mixed liquid with high freshness, such as yellow or light red, the solution has high light transmittance, and the light signal received by the photosensor 10 is strong. The mixed liquid, such as purple or black, has low light transmittance, and the light signal received by the photosensor 10 is weak. A processor 11 electrically connected to the photosensor 10 is fixedly mounted on the side wall of the body 1. The processor 11 is used to receive, process electrical signals and output freshness determination results. The processor 11 is preset with a light signal intensity threshold table corresponding to different freshness levels, and outputs the freshness determination result based on the comparison result between the received digital signal and the threshold table. The LED linear light source 8, photosensor 10 and processor 11 are disclosed in the patent with publication number CN203814014U, titled "A LED Intelligent Stage Lighting Control Device", which belongs to the prior art and its working principle is not described in detail here.

[0022] First, the royal jelly to be tested and the detection reagent are put into the mixing area 4 from the top of the vertical rod 2 according to the amount. At this time, the piston block 7 will be at the top of the detection area 5. Then, the royal jelly and the detection reagent in the mixing area 4 are stirred and mixed by the stirring component to obtain a mixed liquid. The piston block 7 is controlled to move downward by the transmission component. When the piston block 7 moves downward, it will give a downward suction force to the mixed liquid above itself, so that the mixed liquid passes through multiple material ports 6 and enters the detection area 5. Until the piston block 7 is located at the bottom of the detection area 5, the mixed liquid will be located between the photosensor 10 and the LED linear light source 8. Then turn on the LED linear light source 8 and emit light toward the detection area 5. The light will pass through the mixed liquid in the detection area 5 and through the window. The photosensor 10 can detect the light intensity passing through the mixed liquid in real time and convert the light signal into an electrical signal. The processor 11 receives and processes the electrical signal and outputs the freshness judgment result.

[0023] The light signal that penetrates the mixed liquid is received by the photosensor 10, and the change in light intensity is converted into an electrical signal. The processor 11 performs digital analysis and uses objective values ​​as the basis for judgment, eliminating random errors caused by human observation, such as the influence of subjective factors such as the color sensitivity of the tester and the light environment. This can greatly improve the detection accuracy, eliminate the need to compare multiple color cards one by one, and improve the detection efficiency.

[0024] The stirring assembly includes an electric telescopic rod 14 fixedly mounted on the top wall of the body 1, a driving motor 15 fixedly mounted on the bottom end of the driving shaft of the electric telescopic rod 14, a rotating rod 16 fixedly mounted on the bottom end of the output shaft of the driving motor 15, and a plurality of stirring rods 17. The plurality of stirring rods 17 are fixedly mounted on the surface of the rotating rod 16 in a circular shape. The transmission parts include a gear 18 and two rack rods 19. A mounting block is fixedly mounted on the side wall of the vertical rod 2. A rotating shaft 20 is horizontally rotated and mounted on the surface of the mounting block. The gear 18 is fixedly sleeved on the rotating shaft 20. The two rack rods 19 are respectively meshed and connected to both sides of the gear 18. The bottom end of one rack rod 19 is fixedly connected to the surface of the piston block 7 through a first connecting rod, and the top of the other rack rod 19 is fixedly connected to the surface of the driving shaft of the electric telescopic rod 14 through a second connecting rod.

[0025] The electric telescopic rod 14 can move vertically with the driving motor 15 and the stirring rod 17, and the driving motor 15 can rotate the stirring rod 17. When the royal jelly and the detection reagent are put into the mixing area 4, the piston block 7 will be located at the top of the detection area 5. The royal jelly and detection reagent entering the mixing area 4 will accumulate above the piston block 7. Then, the driving motor 15 drives the rotating rod 16 and the stirring rod 17 to rotate to stir and mix the royal jelly and detection reagent in the mixing area 4. After the stirring and mixing is completed, the electric telescopic rod 14 is started to move upward with the driving motor 15, the rotating rod 16 and the stirring rod 17. Under the transmission action between the two rack rods 19 and the gear 18, the piston block 7 will move downward, thereby giving the mixed liquid a downward suction force, so that the mixed liquid in the mixing area 4 enters the detection area 5 through multiple material ports 6, which can speed up the process of transferring the mixed liquid to the detection area 5, improve the detection efficiency and prevent the mixed liquid from being contaminated.

[0026] A collecting box 21 is fixedly installed at the bottom of the body 1, and a through hole connected to the collecting box 21 is opened on the bottom wall of the body 1. The through hole is located just below the vertical rod 2. A discharge port 22 with an isosceles trapezoidal longitudinal section is opened through the upper surface of the piston block 7. A rectangular plate is symmetrically and vertically fixedly installed on the surface of the piston block 7. A baffle 24 is fixedly installed on the side of the two rectangular plates close to each other through a first spring rod 23. A pressing component for controlling the two first spring rods 23 to extend and retract together is provided on the surface of the bottom end of the vertical rod 2. The pressing component includes a V-shaped plate 25 fixedly connected to the surface of the bottom end of the vertical rod 2 through two L-shaped rods. An L-shaped push rod 26 is fixedly installed on the lower surface of the baffle 24. The surface of the V-shaped plate 25 is symmetrically opened. A through-hole 27 is provided for two supporting rods 26 to pass through respectively. A rotating hole is horizontally opened on the wall of the through-hole 27. A circular shaft 28 is horizontally rotatably installed in the rotating hole. A rotating plate 29 and a mounting block are fixedly installed at both ends of the circular shaft 28. A first torsion spring 30 is sleeved on the circular shaft 28. The two ends of the first torsion spring 30 are fixedly connected to the mounting block and the V-shaped plate 25 respectively. The end of the rotating plate 29 away from the circular shaft 28 is restricted from rotating upward by a limiting component. The limiting component includes a rotation limiting block 31 fixedly installed on the end of the rotating plate 29 away from the circular shaft 28. The lower surface of the V-shaped plate 25 is symmetrically provided with rotation limiting holes 32 respectively connected to the two through-holes 27. The upper surfaces of the two rotation limiting blocks 31 respectively abut against the walls of the two rotation limiting holes 32.

[0027] When the piston block 7 is located at the top of the detection area 5, the ends of the two baffles 24 that are close to each other will abut against each other, covering and blocking the lower opening of the discharge port 22 to prevent the mixed liquid from passing through the discharge port 22. As the piston block 7 moves downward, the two push rods 26 will respectively enter the two through-holes 27, and the lower surfaces will respectively abut against the upper surfaces of the two rotating plates 29 located in the two through-holes 27. The rotating plate 29 is subjected to the force of the pressure, and the end away from the circular shaft 28 will rotate downward, and the rotation limit block 31 located at one end of the rotating plate 29 will also rotate out of the rotation limit opening 32 until the mixed liquid passes through the discharge port 22. After the two push rods 26 pass through the two through-holes 27 respectively and no longer abut against the two rotating plates 29, the two rotating plates 29 will quickly rotate and reset under the elastic potential energy of the two first torsion springs 30, and the upper surface of the rotation limit block 31 located at the end of the rotating plate 29 will again abut against the wall of the rotation limit opening 32 until the piston block 7 moves down to the bottom of the detection area 5. At this time, the LED linear light source 8 emits light toward the mixed liquid in the detection area 5, the photosensor 10 detects the light intensity passing through the mixed liquid, and the processor 11 outputs the freshness judgment result.

[0028] After the detection is completed, the electric telescopic rod 14 is started to control the rotating rod 16 and the stirring rod 17 to move down into the mixing area 4. During this process, the piston block 7 will move up in the detection area 5, and the upper surfaces of the two push rods 26 will respectively abut against the lower surfaces of the two rotating plates 29. Since the rotating plates 29 are restricted by the limited rotating block 31 and the limited rotation port 32, the end thereof away from the circular shaft 28 cannot rotate upward, so that the push rod 26 will slide in contact with the inclined surface of the V-shaped plate 25 during the upward movement. Under the action of the inclined surface pressure, the two first spring rods 23 will shrink together, and the ends of the two baffles 24 will no longer abut against each other, so that the bottom opening of the discharge port 22 is in an open state. Located above the piston block 7, the tested mixed liquid will flow out from the bottom opening of the discharge port 22 and fall into the collecting box 21, thereby completing automatic unloading. There is no need to manually unload the mixed liquid in the detection area 5, which can further improve the detection efficiency. Then, as the piston block 7 moves upward, until the two push rods 26 no longer contact the V-shaped plate 25, the two baffles 24 will quickly move and reset under the elastic potential energy of the two first spring rods 23, and the ends of the two baffles 24 will again resist each other, thereby covering and sealing the bottom opening of the discharge port 22. At this time, the subsequent royal jelly to be tested and the detection reagent are put into the mixing area 4 for stirring and mixing.

[0029] The feed port 6 is conical, and the diameter of the feed port 6 decreases from top to bottom. When the piston block 7 moves downward, it will give the mixed liquid a downward suction force, so that the mixed liquid enters the detection area through multiple feed ports 6. Since the feed port 6 is conical, the diameter of the feed port 6 decreases from top to bottom, when the mixed liquid passes through the liquid port 6, the bubbles contained in it will be squeezed and eliminated by the mouth wall of the feed port 6, avoiding subsequent light from scattering and refraction at the bubble interface when passing through the mixed liquid containing bubbles, causing abnormal fluctuations in the light intensity received by the photosensor 10, thereby ensuring the accuracy of the detection data.

[0030] A mounting opening 33 is symmetrically provided on the upper surface of the piston block 7, and a rotating rod 34 is sealed and rotatably installed in the mounting opening 33. A scraper plate 35 is fixedly installed on the surface of the rotating rod 34, and the two scrapers 35 respectively correspond to the two sides of the detection area 5 through which the light emitted by the LED linear light source 8 passes. Circular holes 36 are provided on the left and right walls of the mounting opening 33, and circular rods 37 are fixedly installed at both ends of the rotating rod 34. The ends of the two circular rods 37 away from each other are rotatably connected to the hole walls of the two circular holes 36 respectively, and a second torsion spring 38 is sleeved on the circular rod 37. The two ends of the second torsion spring 38 are fixedly connected to the hole walls of the circular holes 36 and the ends of the rotating rod 34 respectively. The two rotating rods 34 are controlled to rotate relative to each other by a pushing assembly, which includes two L-shaped push rods 39, two L-shaped connecting rods 40 and two force blocks 41 respectively fixedly mounted on the ends of the two connecting rods 40. The longitudinal section of the force block 41 is a right-angle triangle The upper surface of the baffle 24 is provided with a feed port 42, and the lower surface of the baffle 24 is fixedly installed with a rectangular frame 43 connected to the feed port 42, and a slider 44 is sealed and slidably installed in the rectangular frame 43, and a placement block is fixedly installed on the inner wall of the rectangular frame 43. The upper surface of the placement block is fixedly installed with a second spring rod 45 fixedly connected to the bottom end of the slider 44, and the lower surface of the slider 44 is fixedly installed with a U-shaped rod 46. The two U-shaped rods 46 are fixedly connected to one end of the two push rods 39 at one end away from the slider 44. The piston block 7 is symmetrically provided with operating ports 47 respectively connected to the two mounting ports 33, and the two connecting rods 40 are respectively located in the two operating ports 47. The lower surface of the piston block 7 is symmetrically provided with sliding ports 48 respectively connected to the two operating ports 47. The ends of the two push rods 39 away from the U-shaped rod 46 pass through the two sliding ports 48 and respectively resist the inclined surfaces of the two force blocks 41.

[0031] When there is no mixed liquid above the piston block 7, the two sliders 44 will not be affected by the gravity of the mixed liquid, so that the slider 44 will be at the highest point under the elastic potential energy of the second spring rod 45. At this time, the top of the slider 44 will be at the same horizontal line with the top of the feed port 42, and the push rod 39 fixedly connected to the slider 44 through the U-shaped rod 46 will also be at the highest point and will not give thrust to the force-bearing block 41, so that the scraper 35 fixedly connected to the surface of the rotating rod 34 will be in a vertical state under the elastic potential energy of the second torsion spring 38, and its end will not be against the inner wall of the detection area 5. When the piston block 7 is at the top in the detection area 5, and then the royal jelly and detection reagent are put into the mixing area 4, part of the royal jelly and detection reagent will enter the discharge port 22 from multiple feeding ports 6. At this time, the two sliders 44 will move downward under the gravity of the royal jelly and detection reagent, and the second spring rod 45 will contract, and the push rod 39 will also move downward, and its end It will slide in contact with the inclined surface of the force-bearing block 41, giving the force-bearing block 41 a thrust, causing the rotating rod 34 to rotate with the scraper plate 35 until the scraper plate 35 is away from the end of the rotating rod 34 and abuts against the inner wall of the detection area 5. At this time, the slider 44 can no longer move down, and the rotating rod 34 and the scraper plate 35 will not move down anymore. Then, when the stirring assembly completes the mixing of the royal jelly and the detection reagent, the piston block 7 moves down with the mixed liquid, and the two scrapers 35 will respectively slide in contact with the two oppositely arranged inner walls of the detection area 5 through which the light of the LED linear light source 8 passes, thereby scraping off the mixed liquid that has been previously detected and remains on the surface of the two inner walls, avoiding the residual mixed liquid film from attenuating the light intensity and eliminating the interference of the residual sample on the light signal. When it is necessary to clean the residue scraped by the scraper plate 35, the residue scraped by the scraper plate 35 can be cleaned by controlling the piston block 7 to move out from the inside of the detection area 5.

[0032] The push force given to the force block 41 by the push rod 39 gradually decreases, and the rotating rod 34 will also gradually rotate and reset with the scraper plate 35 under the elastic potential energy of the second torsion spring 8, and the scraper plate 35 will be The ends of the material plates 35 will no longer contact the inner wall of the detection area 5 until the mixed liquid flows out of the detection area 5, and the ends of the two baffles 24 will contact each other again to block the bottom opening of the discharge port 22. At this time, the two sliders 44 have also moved up and reset, and the two push rods 39 no longer contact the two force blocks 41. The two scraper plates 35 will also rotate to a vertical state again, that is, as the piston block 7 moves upward, it will be located above the piston block 7. After the mixed liquid to be tested is discharged, the two scraper plates 35 will no longer contact the inner wall of the detection area 5 until the piston block 7 moves down with the subsequent mixed liquid to be tested. The two scraper plates 35 will not contact the inner wall of the detection area 5 until the piston block 7 moves down with the subsequent mixed liquid to be tested. The two scraper plates 35 will avoid contacting the inner wall of the detection area 5 all the time, thereby pushing the mixed liquid remaining on the inner wall of the detection area 5 upward during the upward movement, making it impossible to remove it.

[0033] The longitudinal section of the slider 44 is a right-angled trapezoid, and a guide port 49 is inclined on the upper surface of the feed port 42. The inclined surface of the slider 44 corresponds to the inclined surface of the guide port 49 and is arranged in parallel. As the mixed liquid is discharged, the slider 44 will gradually move upward, and the mixed liquid in the feed port 42 will slide down along the top inclined surface of the slider 44 to be discharged from the guide port 49, thereby preventing the mixed liquid in the feed port 42 from being unable to be discharged.

[0034] In the present invention, the royal jelly to be tested and the detection reagent are put into the mixing area 4 of the vertical rod 2, the piston block 7 is located at the top of the detection area 5, the stirring assembly mixes the two to obtain a mixed liquid, and the transmission component controls the piston block 7 to move downward, generating a suction force to allow the mixed liquid to enter the detection area 5 through the feed port 6. After the piston block 7 reaches the bottom of the detection area 5, the LED linear light source 8 emits light through the mixed liquid, the photosensor 10 detects the light intensity and converts it into an electrical signal, and the processor 11 analyzes the signal and outputs the freshness judgment result. This process uses the photosensor 10 and the processor 11 to cooperate to realize digital detection, eliminate human errors, and improve accuracy and efficiency.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
