Description

Technical Field

[0001] The present invention relates to the technical field of fungal detection, and particularly to a kit for detecting mycotoxins. Background Art

[0002] A mycotoxin detection device is a professional device used to detect the content of mycotoxins in samples such as food and feed. Detection by color change of test strips is a commonly used method in rapid mycotoxin detection, and its basic principle is competitive inhibition immunochromatography. Specifically, a test strip usually includes a test line (T line) and a quality control line (C line). Mycotoxins in the sample to be tested will bind to specific antibodies or antigens on the test strip, and this binding will change the color intensity of the T line and the C line. By observing and comparing the color changes of the T line and the C line, the content of mycotoxins in the sample to be tested can be judged. This method is simple to operate and convenient for observing the detection results.

[0003] When detecting mycotoxins, first, the fungal sample needs to be dropped onto the test strip to be detected. However, during the feeding process, usually, the experimenter manually feeds the sample, that is, the fungus is fed in a fixed-position manner, which will cause the fungus to be unevenly distributed on the test strip, resulting in large fluctuations in the color changes on the same test strip, making it difficult for the detection results to accurately reflect the mycotoxin content of the overall sample.

Detailed implementation manners

[0016] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0017] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0018] Refer to Figures 1 to 10 , a kit for detecting mycotoxins, comprising a box body 1, an outer baffle 2, an inner baffle 3, a cover 31, a motor 4, a rotating shaft 5, a rotating assembly 6, an expanding assembly 7 and a material guiding assembly 8; the box body 1 is arranged on a laboratory bench, the outer baffle 2 and the inner baffle 3 are both fixed on the upper end surface of the box body 1, and the inner baffle 3 is located inside the outer baffle 2. The cover 31 is hermetically and detachably installed on the upper ends of the outer baffle 2 and the inner baffle 3. The motor 4 is fixedly installed at the center of the upper end surface of the box body 1. The output shaft of the motor 4 rotates through the box body 1. The rotating shaft 5 is fixed to the output end of the motor 4. The rotating assembly 6 is arranged at the bottom inside the box body 1. The expanding assembly 7 is arranged in the middle inside the box body 1. The material guiding assembly 8 is arranged at the top inside the box body 1.

[0019] In the above, the annular feeding space between the outer baffle 2 and the inner baffle 3 is used to place the fungi to be detected. An air hole 32 is arranged on the upper end of the cover 31. That is to say, during the detection of mycotoxins, the annular feeding space is kept at the same air pressure as the outside world to ensure that the fungi inside can be normally fed.

[0020] In addition, the motor 4 can be driven bidirectionally.

[0021] As a preferred embodiment, the rotating assembly 6 includes a driving wheel 61, a driven wheel 62, a transfer shaft 63, and a first rotating magnetic strip 64; the driving wheel 61 is fixed on the rotating shaft 5, a plurality of driven wheels 62 are circumferentially arranged, extension shafts are fixed at the lower ends of the plurality of driven wheels 62, and the plurality of extension shafts are respectively sleeved and rotatably arranged at the inner bottom of the box body 1. The plurality of driven wheels 62 are all meshed with the driving wheel 61. The plurality of transfer shafts 63 are circumferentially arranged and are respectively fixedly installed at the upper centers of the driven wheels 62. The plurality of first rotating magnetic strips 64 are circumferentially arranged and are respectively fixedly installed on the upper end faces of the plurality of transfer shafts 63.

[0022] It should be explained that when the motor 4 drives the rotating shaft 5 to rotate, the rotating shaft 5 can drive the driving wheel 61 to rotate. Through the meshing of the driving wheel 61 and the plurality of driven wheels 62, the plurality of transfer shafts 63 and the plurality of first rotating magnetic strips 64 can rotate synchronously with their respective corresponding driven wheels 62.

[0023] As a preferred embodiment, the expanding assembly 7 includes a guiding frame 71, a turntable 72, a T-shaped block 73, a sliding rod 74, a fixed disk 75, a test paper disk 76, and a second rotating magnetic strip 77; the guiding frame 71 is fixed to the inner wall of the box body 1 through a plurality of fixing rods 711. A plurality of guiding grooves are formed on the guiding frame 71. The turntable 72 is sleeved and rotatably arranged on the rotating shaft 5. The turntable 72 is located at the upper end of the guiding frame 71, and a frosted ring is arranged at the connection between the turntable 72 and the rotating shaft 5. A plurality of arc-shaped grooves 721 are circumferentially formed on the turntable 72. The plurality of T-shaped blocks 73 are respectively slidably arranged in the plurality of arc-shaped grooves 721. The plurality of sliding rods 74 are circumferentially arranged and are respectively slidably arranged in a plurality of sliding grooves. The plurality of T-shaped blocks 73 are respectively fixed at the upper ends of the mutually adjacent sides of the plurality of sliding rods 74. The plurality of fixed disks 75 are circumferentially arranged and are respectively fixed at the mutually remote ends of the plurality of sliding rods 74. The plurality of test paper disks 76 are circumferentially arranged and are respectively rotatably arranged in the fixed disks 75. The plurality of second rotating magnetic strips 77 are arranged and are respectively fixed at the bottom ends of the test paper disks 76.

[0024] That is to say, when the driven wheel 62 drives the first rotating magnetic strip 64 to rotate, the first rotating magnetic strip 64 drives the second rotating magnetic strip 77 to rotate synchronously through magnetic force, and then the test paper disk 76 can rotate in the fixed disk 75.

[0025] As a preferred embodiment, a plurality of through holes are formed on the side wall of the box body 1. An inner built-in groove 11 is formed at the lower end of the through hole. A blocking block 12 is slidably penetrated in the inner built-in groove 11. The upper end cross section of the blocking block 12 is configured as a trapezoid, and a compression spring 13 is connected between the blocking block 12 and the inner wall of the inner built-in groove 11.

[0026] It should be noted that when the motor 4 drives the rotating shaft 5 to rotate forward, the rotating shaft 5 will drive the turntable 72 to rotate forward synchronously through the frictional force of the frosted ring. During the forward rotation of the turntable 72 with the rotating shaft 5, the inner walls of the multiple arc-shaped grooves 721 will drive the multiple T-shaped blocks 73 to move away from each other synchronously, so that the sliding rod 74 will drive the fixed disk 75 to move outward from the box body 1. During this period, the fixed disk 75 will squeeze the inclined surface of the blocking block 12, and its vertical component force will cause the blocking block 12 to move downward, and then the fixed disk 75 will pass through the perforation, so that the test strip in the test strip tray 76 can be replaced outside the box body 1 for cyclic detection. When the T-shaped block 73 is limited after moving from the inner side wall of the arc-shaped groove 721 to the outer side wall, the turntable 72 stops rotating forward. After that, the rotating shaft 5 will carry the frosted ring and slip in the turntable 72; When the motor 4 drives the rotating shaft 5 to rotate reversely, similarly, the rotating shaft 5 will drive the turntable 72 to rotate reversely synchronously through the frictional force of the frosted ring. During the reverse rotation of the turntable 72 with the rotating shaft 5, the inner walls of the multiple arc-shaped grooves 721 will drive the multiple T-shaped blocks 73 to move together synchronously, so that the sliding rod 74 will drive the fixed disk 75 to move inward into the box body 1. That is to say, the test strip in the test strip tray 76 will move into the box body 1 after being replaced outside the box body 1. When the fixed disk 75 completely disengages from the perforation, the blocking block 12 will block the perforation under the elastic force of the compression spring 13, so as to ensure that the inside of the box body 1 remains closed during the detection of mycotoxins, avoid interference of external factors on the detection results, and ensure the accuracy of the detection results. When the T-shaped block 73 is limited after moving from the outer side wall of the arc-shaped groove 721 to the inner side wall, the turntable 72 stops rotating forward. After that, the rotating shaft 5 will carry the frosted ring and slip in the turntable 72, that is, the fixed disk 75 remains stationary.

[0027] As a preferred embodiment, the material guiding assembly 8 includes a pawl 81, a cam 82, a ratchet wheel 83, a moving stop block 84 and a material guiding funnel 85; the pawl 81 is connected to the rotating shaft 5 by a torsion spring, the cam 82 is sleeved and rotatably arranged on the rotating shaft 5, the ratchet wheel 83 is fixed on the inner wall of the cam 82, and the pawl 81 meshes with the ratchet wheel 83. A triangular through hole 14 is formed in the upper end circumference of the box body 1, and a plurality of triangular through holes 14 are all communicated with the annular feeding space. A clamping groove 15 is formed in the lower end of the top of the box body 1 on both sides of the triangular through hole 14. The cross section of the clamping groove 15 is T-shaped. A plurality of moving stop blocks 84 are arranged circumferentially. Blocks are fixed on both sides of the upper end thereof, and the cross section of the block is T-shaped. The block is hermetically and slidably arranged in the clamping groove 15, and a return spring is connected between the block and the inner wall of the clamping groove 15. A rectangular hole 841 is formed in the center of the moving stop block 84, and the rectangular hole 841 is slidably arranged at the lower end of the triangular through hole 14. The material guiding funnel 85 is fixed at the lower end of the moving stop block 84. One ends of the plurality of moving stop blocks 84 close to each other are configured as arc portions, and the cam 82 is intermittently and movably in contact with the arc portions of the plurality of moving stop blocks 84.

[0028] It should be explained that when the motor 4 drives the rotating shaft 5 to rotate in the reverse direction, the pawl 81 meshes with the ratchet wheel 83, so that the rotating shaft 5 will drive the cam 82 to rotate. On the contrary, when the motor 4 drives the rotating shaft 5 to rotate in the forward direction, the pawl 81 idles in the ratchet wheel 83, and the cam 82 abuts against the arc portion of one of the moving stop blocks 84 and there is no mutual force.

[0029] For details, please refer to Figures 6 to 10 , when the rotating shaft 5 rotates in the reverse direction, the cam 82 will rotate, and the cam will exert a squeezing effect on the arc portion of the moving stop block 84. The circumferential component of this squeezing force will push the moving stop block 84 to move towards the outside of the box body 1. At the same time, the material guiding funnel 85 will move synchronously. Therefore, the material guiding funnel 85 will move from directly above the center of the test paper tray 76 to the upper edge of the test paper tray 76. During this process, the test paper tray 76 always remains in a rotating state. Therefore, the fungi falling on the test paper tray 76 are in a planar spiral shape, as shown in Figure 10 , that is, in the shape of mosquito coils, so that the fungi falling on the surface of the test paper tray 76 can fill the entire test paper tray 76, thereby increasing the effective use area of the test paper in the test paper tray 76; moreover, initially, when the cam 82 and the moving stop block 84 are not squeezed, the moving stop block 84 completely blocks the triangular through hole 14. As the moving stop block 84 moves, the communication area between the rectangular hole 841 and the triangular through hole 14 gradually increases, so that the feeding amount of the fungi gradually increases; it should be noted that please refer to Figure 10, when the fungus is fed in a planar spiral manner, if the feeding amount remains consistent all the time, within the same rotation angle α, the feeding speed of the inner layer is less than that of the outer layer, which will result in a larger feeding amount of the inner layer than that of the outer layer. Therefore, by using the gradually increasing communication area between the rectangular hole 841 and the triangular through-hole 14, the amount of fungus per unit area on the surface of the test paper disk 76 can be kept uniform when the test paper disk 76 rotates, thereby ensuring that the fungus on the surface of the test paper disk 76 can be evenly distributed under the condition of the maximum effective use area, and improving the accuracy of the detection result.

[0030] It should be noted that when the fixed disk 75 moves from the outside of the box body 1 to the inside of the box body 1, the cam 82 just turns from one moving stop 84 to the next moving stop 84 during this process. During this period, the multiple rectangular holes 841 and the corresponding triangular through-holes 14 are in a non-connected state, that is, the material guiding funnel 85 does not feed materials, thus avoiding the situation that the test paper disk 76 starts to feed materials before it moves into the box body 1 and reaches the stationary state along with the fixed disk 75.

[0031] Specifically, during implementation, first, the motor 4 drives the rotating shaft 5 to rotate forward. The rotating shaft 5 drives the turntable 72 to rotate forward. The inner wall of the arc-shaped groove 721 pushes multiple T-shaped blocks 73 to move outward synchronously, thereby driving multiple fixed disks 75 to move outward synchronously towards the outside of the box body 1. When the fixed disk 75 passes through the perforation and reaches the outside of the box body 1, the limited length of the arc-shaped groove 721 will limit the further outward movement of the fixed disk 75. As a result, the fixed disk 75 will be stationary outside the box body 1. During this period, the test strips in the test strip tray 76 are replaced. And during this period, since the pawl 81 idles in the ratchet 83, the cam 82 remains stationary, so no material is fed during this period. After the replacement of the test strips is completed, the motor drives the rotating shaft 5 to rotate in the reverse direction. Initially, the rotating shaft 5 drives the turntable 72 to rotate in the reverse direction. The inner wall of the arc-shaped groove 721 drives multiple T-shaped blocks 73 to move inward synchronously, thereby driving multiple fixed disks 75 to move inward synchronously towards the inside of the box body 1. Similarly, due to the limited length of the arc-shaped groove 721, the further inward movement of the fixed disk 75 is restricted. Therefore, the fixed disk 75 will be stationary inside the box body 1. During this period, the cam 82 does not exert any squeezing effect on the moving stop block 84. Subsequently, the rotating shaft 5 continues to rotate, driving the cam 82 to rotate in reverse synchronously. The cam 82 will squeeze the moving stop block 84, and the moving stop block 84 will drive the feeding funnel 85 to move from directly above the center of the test strip tray 76 to the upper edge part of the test strip tray 76. During this process, the test strip tray 76 is always in a rotating state, so that the fungi falling on the test strip tray 76 form a planar spiral shape, that is, a mosquito coil shape. Moreover, initially, when the cam 82 and the moving stop block 84 are not squeezed, the moving stop block 84 completely blocks the triangular through hole 14. As the moving stop block 84 moves, the communication area between the rectangular hole 841 and the triangular through hole 14 gradually increases, so that the feeding amount of the fungi gradually increases. Therefore, by using the gradually increasing communication area between the rectangular hole 841 and the triangular through hole 14, the amount of fungi per unit area on the surface of the test strip tray 76 is kept uniform when it rotates. When the cam 82 rotates one circle, the feeding work of multiple test strip trays 76 is completed. Subsequently, the motor 4 is turned off. After the test strips and the fungi have fully reacted, the motor 4 is started and the rotating shaft 5 is driven to rotate forward, so that the multiple test strip trays 76 after the reaction will be removed from the closed box body 1 for direct observation of their color changes, and finally an accurate test result can be obtained.

[0032] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
