Description

Technical Field

[0001] The invention relates to the technical field of experimental auxiliary instruments, and in particular to a device for softening samples of Chinese medicinal materials microscopic experiments. Background Art

[0002] Embedding is the process of immersing certain special supporting substances into the interior of the tissue block, using the physical properties of the supporting substances to embed the entire tissue, and finally solidifying it into a uniform and consistent hard solid structure so that the slicer can prepare extremely thin slices. Specifically, when it comes to embedding Chinese medicinal seeds, since the outer layer of the seeds contains a hard shell, it will affect the subsequent slicing. Therefore, before embedding the seeds, the hard shell of the outer layer of the seeds needs to be softened.

[0003] However, in actual operation, due to the lack of unified standards for softening methods for different seeds, the softening effect is often unsatisfactory. In experiments, excessive seed softening often causes the seed coat to be damaged or missing, or even causes the seeds to break, affecting subsequent seed sectioning observation.

[0004] In view of this, we decided to develop an experimental equipment to achieve the best softening effect by changing the four factors of temperature, humidity, softener dosage and soaking time, and to establish softening system standards for different types of seeds. Summary of the Invention

DETAILED DESCRIPTION

[0050] The following describes the implementation of the present invention using specific embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. Obviously, the embodiments described are only a portion of the present invention, not all of it. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.

[0051] Please refer to Figures 1-9 The present invention discloses a device for softening samples of Chinese medicinal materials for microscopic experiments, which is used to perform softening experiments on medicinal plant seeds. The device comprises a rotating carrier 1, an upper frame 3, and a lower frame 5. The top of the rotating carrier 1 is coaxially connected to a power circulation device 6. The power circulation device 6 not only drives the rotating carrier 1 but also absorbs condensed liquid water in the experimental area 53 to prevent siltation caused by mist condensation. The rotating carrier 1 is used to hold samples (plant seeds). As the rotating carrier 1 rotates, the sample can be fully exposed to water in the experimental area 53, achieving temperature neutralization.

[0052] In this embodiment, if Figure 2 The power circulation device 6 is installed inside the upper frame 3. The bottom of the upper frame 3 is connected to the lower frame 5. At the same time, a sealing door 2 is provided at the end of the lower frame 5, thereby wrapping the experimental area 53 to prevent heat and moisture loss.

[0053] Further explanation, such as Figure 8 The lower frame 5 includes an atomization area 51, a diversion area 52 and an experimental area 53. The rotating carrier 1 is suspended in the experimental area 53. On this basis, the atomization area 51, the diversion area 52 and the experimental area 53 are arranged in sequence, and the experimental area 53 is connected to the atomization area 51 through the diversion area 52, so that the mist water for softening the seeds can be recycled. In addition, a titrator 9 is also provided in the middle of the diversion area 52 for dripping a softener into the rotating carrier 1. Among them, the atomization area 51 atomizes the liquid water to generate mist, and the mist enters the diversion area 52 to form a cold and hot mist flow that enters the experimental area 53 and softens the medicinal plant seeds in the rotating carrier 1. In this embodiment, the flow rate of the cold and hot mist flows formed by the mist can be controlled by the regulating motor 524 of the diversion area 52, and further, by adjusting the ratio of the cold and hot mist flows entering the experimental area 53, the temperature in the experimental area 53 can be quickly adjusted.

[0054] In some embodiments, as Figure 2The power circulation device 6 includes a stepper motor 61, a flexible shaft 63 and a peristaltic pump 65, wherein the stepper motor 61 is installed in the upper frame 3, and the output end of the stepper motor 61 is coaxially connected to the worm 62, and the worm 62 is meshingly connected to the worm gear 64. On the one hand, the worm gear 64 drives the rotating carrier 1 to rotate, and on the other hand, the worm 62 is coaxially connected to the worm gear 64. One end of the flexible shaft 63 is connected to the worm 62 and the other end is connected to the peristaltic pump 65 to drive the peristaltic pump 65 to operate, and the input end of the peristaltic pump 65 is connected to the experimental area 53 through the rotating carrier 1, and the output end is connected to the atomization area 51. Therefore, while the worm 62 rotates, the peristaltic pump 65 can also suck the accumulated water in the experimental area 53 into the atomization area 51, thereby realizing the recycling of water. To further illustrate, as Figure 3 The black arrows represent condensed liquid water, and the white arrows represent atomized droplets. The droplets enter the experimental area 53 and gather to form liquid water. Since the input and output ends of the peristaltic pump 65 are both connected to the rubber hose, and the rotating shaft of the rotating carrier 1 is hollow, the rubber hose can be inserted into the rotating carrier 1 to absorb water.

[0055] In this embodiment, if Figure 9 The rotating carrier 1 includes a spline 11, a hollow tube 12 and a carrier plate 13, wherein the carrier plate 13 is fixedly arranged on the hollow tube 12, and the spline 11 is installed at the upper end of the hollow tube 12. The peristaltic pump 65 can absorb water in the hollow tube 12 through a hose, and the spline 11 is inserted into the center of the worm gear 64 and drives the carrier plate 13 to rotate through the worm gear 64. In the process of driving the carrier plate 13 to rotate, not only can the seeds be fully contacted with the mist, but also the cold and hot mist flows can be fully mixed and gathered into a water flow, thereby maintaining the constant temperature of the experimental area 53.

[0056] In some embodiments, as Figure 7 The experimental area 53 includes a central positioning bearing 531 and a funnel base 532. The center of the funnel base 532 is concave, and the bottom end of the hollow tube 12 is inserted into the central positioning bearing 531. The central positioning bearing 531 is located at the center of the funnel base 532, thereby gathering accumulated water to the position of the hollow tube 12.

[0057] In this embodiment, if Figure 8The diversion area 52 includes a reagent tank 521, a temperature-variable tank 523 and an adjustment motor 524. The reagent tank 521 is used to install a titrator 9, and the titrator 9 can be extended into the test area 53 to add a softener to the sample. On the other hand, two temperature-variable tanks 523 are symmetrically arranged on both sides of the reagent tank 521, and a guide bar 522 is installed at the bottom of any temperature-variable tank 523. A valve core 8 is slidingly arranged on the guide bar 522. The valve core 8 is used to adjust the flow rate of mist water flowing out of the temperature-variable tank 523, thereby controlling the humidity of the experimental area. In this technical solution, since the seeds are always in a mist environment with the most abundant oxygen, the energy released by their respiration can be maximized, so the efficiency of absorbing water and mineral nutrients does not change, and they can always maintain an efficient metabolic and absorption state. Compared with the method of soaking in liquid water, it is easier to soften the seeds, and it is also easier to control the environment of the experimental area, thereby facilitating the formation of experimental standards for seed softening.

[0058] Specifically, such as Figure 5 and Figure 6 The valve core 8 includes a valve block 81 and a gear 83. Two regulating motors 524 are respectively arranged on the sides of the two temperature-changing tanks 523. The regulating motor 524 is coaxially connected to the gear 83, and the side of the gear 83 is meshed with the rack 82 for transmission connection. A rack 82 is provided on the side of the valve block 81, so that the regulating motor 524 can drive the valve core 8 to slide along the guide bar 522 through the gear 83.

[0059] In some embodiments, as Figure 2 The atomization area 51 includes a valve slot 511, a water reservoir 512 and an atomization pool 513. The valve core 8 is suitable for extending into the valve slot 511. There are two valve slots 511, which are symmetrically arranged in the water reservoir 512. The atomization pool 513 is arranged in the water reservoir 512 and is connected to the atomization pool 513. At the same time, a misting device 10 is arranged in the atomization pool 513 for generating water mist.

[0060] Based on the previous embodiment, Figure 5 The misting device 10 includes a buoy 101 and an ultrasonic atomizer 102. The buoy 101 is provided in the atomizing pool 513. The buoy 101 floats along the inner wall of the atomizing pool 513, and the ultrasonic atomizer 102 is inserted in the center. It should be noted that the mist entering the experimental area 53 is not steam, but small water droplets generated by the high-frequency vibration of the ultrasonic atomizer 102. Groups of small water droplets rise upward and enter the diversion area 52. After temperature adjustment, they enter the experimental area 53. In addition, since the atomizing pool 513 is connected to the water reservoir 512, the liquid levels of the atomizing pool 513 and the water reservoir 512 are kept flush, and the buoy 101 floats on the water surface of the atomizing pool 513, which can make the ultrasonic atomizer 102 always in contact with the liquid water in the atomizing pool 513, thereby continuously releasing water mist.

[0061] In this embodiment, if Figure 5 A temperature control device 7 is installed on the top of the diversion area 52. The cover plate 71 of the temperature control device 7 is sealed on the two temperature variable grooves 523, and a thermoelectric cooling plate is installed on the bottom of the cover plate 71. Specifically, the thermoelectric cooling plate includes a cold end 72 and a hot end 73. The cold end 72 and the hot end 73 are respectively inserted into the two temperature variable grooves 523 to change the temperature of the mist.

[0062] In this embodiment, if Figure 4 The titrator 9 includes a container 91, a titration motor 92 and a piston 93, wherein a nozzle 95 is provided on the side of the container 91, and the nozzle 95 is suitable for extending into the experimental area 53, and the titration motor 9 is installed at the bottom of the container 91 and is coaxially connected with the screw 94. The screw 94 is located in the inner cavity of the container 91, and the inner cavity of the container 91 is against the outer edge of the piston 93. The center of the piston 93 is threadedly connected with the screw 94. Since the softener is stored above the piston 93, when the titration motor 92 drives the screw 94 to rotate, the piston 93 pushes the softener and sprays the softener into the experimental area in a quantitative manner, thereby accelerating the softening of the seeds.

[0063] In this embodiment, if Figure 1 A camera is installed in the experimental area 53, and the camera is connected to an external display 4. The display 4 can clearly observe the image of the plant seed soaking and softening. Furthermore, the display 4 is a touch screen and is connected to the processor. The device can transmit the experimental soaking and softening data to the computer for analysis, thereby obtaining the optimal softening solution. Furthermore, based on the structure of this device, the processor can dynamically adjust the regulating motor 524, stepper motor 61, and thermoelectric cooling chip through the temperature sensor and humidity sensor installed in the experimental area 53 to ensure that the environment in the experimental area 53 remains stable. In addition, after obtaining the standard parameters for softening specific plant seeds, the softening parameters of different types of seeds can be input into the processor, so that the softening of plant seeds of that type can be repeated.

[0064] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications and improvements may be made thereto. Therefore, such modifications and improvements, without departing from the spirit of the present invention, are intended to be within the scope of protection claimed herein.
