Description

Technical Field

[0001] This invention relates to the field of detection device technology, specifically to a device for detecting the content of polysaccharide components in plant extracts. Background Technology

[0002] Plants are one of the main forms of life, including familiar organisms such as trees, shrubs, vines, grasses, ferns, green algae, and lichens. Most of the energy for green plants comes from sunlight through photosynthesis. Temperature, humidity, light, and freshwater are the basic requirements for plant survival. Using light energy and chlorophyll, and under the catalysis of enzymes, green plants perform photosynthesis, utilizing water, inorganic salts, and carbon dioxide to release oxygen, absorb carbon dioxide, and produce organic matter such as glucose for their own use. In plant research, plant extracts are often obtained through physical or chemical methods. Current plant extract detection devices typically involve dripping the extract onto a detection lens for analysis.

[0003] The existing Chinese patent (publication number: CN213633153U) belongs to the field of liquid component detection technology, and in particular to a device for detecting the polysaccharide content of plant extracts. The device includes a body with a groove at its top. A sensor for detecting sugar content is fixedly connected inside the groove. A limiting ring is fixedly connected to the top of the body at a position corresponding to the groove. A fixing ring is screwed to the outer wall of the limiting ring. The fixing ring has a threaded groove that mates with the limiting ring, and the fixing ring is screwed to the outer wall of the limiting ring through the threaded groove. This device allows the extension tube to be removed from the groove and the detection lens to detach from the body, avoiding the situation where the detection lens is fixed in the groove and difficult to clean, thus improving the cleaning quality of the detection lens. Moreover, after the lens wears out, the operator can directly replace the detection lens. The device has a simple structure, is easy to operate, and is highly practical.

[0004] The detection device in the aforementioned patent is inconvenient to disassemble and replace the detection lens during use, which reduces the device's performance.

[0005] Based on this, the present invention designs a device for detecting the polysaccharide content of plant extracts to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a device for detecting the polysaccharide content in plant extracts, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a device for detecting the content of polysaccharide components in plant extracts, comprising a body, wherein a display screen, buttons and an end cap are provided on the upper surface of the body, and the display screen is located between the end cap and the buttons;

[0008] The upper end face of the device is provided with a detection chamber, which is located on the lower end face of the end cap. A support plate is fixedly installed on the inner side wall of the detection chamber near the lower end. A detection lens is provided on the support plate. A positioning plate is provided on the outer side of the detection lens. A sleeve rod is fixedly installed on the outer side of the positioning plate. An insert rod is inserted into the sleeve rod. A spring is fixedly installed between the sleeve rod and the inner side wall of the detection chamber.

[0009] Preferably, a limiting frame is slidably installed on the inner sidewall of the detection cavity near the upper end, and a suction tube is fixedly installed in the middle of the inner sidewall of the limiting frame.

[0010] Preferably, an air bladder is fixedly connected to the upper end of the straw, and a water outlet pipe is fixedly installed on the lower end of the straw.

[0011] Preferably, the water outlet pipe and the suction pipe are integrated components, and the lower end face of the water outlet pipe corresponds to the center position of the detection lens.

[0012] Preferably, an annular groove is formed on the lower end face of the end cap, and an annular plate is fixedly installed at the edge of the upper end face of the detection cavity.

[0013] Preferably, the annular plate and the detection cavity are an integrated component, and the annular plate is installed inside the annular groove by threads.

[0014] Preferably, the side of the positioning plate near the detection lens is arc-shaped, and several positioning plates are placed in a ring at equal intervals. The positioning plates are slidably mounted on the upper surface of the support plate, and the lower surface of the detection lens is in close contact with the upper surface of the support plate near the edge.

[0015] Preferably, a sensor for detecting sugar content is fixedly installed inside the device, and the detection lens is made of prism material, with the detection lens closely attached to the top of the sensor.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. Drop the plant extract to be tested onto the detection lens and cover it with the end cap to seal the detection chamber. The sensor detects the polysaccharide content of the extract on the detection lens. Place the detection lens on the support plate and push the positioning plate to both sides. The positioning plate pushes the sleeve rod to move along the insertion rod and squeezes the spring. Under the reaction force of the spring, the side of the positioning plate contacts the outer side of the detection lens, thereby positioning the detection lens. Push the positioning plate in the opposite direction to separate it from the detection lens and move the detection lens upward. The detection lens can then be removed from the inside of the detection chamber, making it easy to disassemble and replace the detection lens and improving the performance of the device.

[0018] 2. The longitudinally moving limiting frame moves the pipette vertically above the detection lens, aligning the water outlet tube on the pipette with the position of the extractant. The air bladder is pinched and pressure is applied to draw the extractant into the pipette. The limiting frame is then placed inside the detection chamber, aligning the water outlet tube on the pipette with the center of the detection lens. The air bladder is pressed, squeezing the extractant from the pipette onto the detection lens. This allows the user to easily drip the extractant onto the detection lens, facilitating subsequent detection and reducing the impact of inaccurate drip placement on subsequent tests, thus improving the device's performance.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] Please see Figures 1 to 5 The present invention provides a technical solution for a device for detecting the content of polysaccharide components in plant extracts: a device for detecting the content of polysaccharide components in plant extracts includes a body 1, and a display screen 2, a button 3 and an end cover 4 are provided on the upper surface of the body 1, with the display screen 2 located between the end cover 4 and the button 3.

[0031] The upper end face of the device body 1 is provided with a detection cavity 5, which is located on the lower end face of the end cover 4. A support plate 9 is fixedly installed on the inner side wall of the detection cavity 5 near the lower end. A detection lens 8 is provided on the support plate 9. A positioning plate 10 is provided on the outer side of the detection lens 8. A sleeve rod 11 is fixedly installed on the outer side of the positioning plate 10. An insert rod 13 is inserted into the sleeve rod 11. A spring 12 is fixedly installed between the sleeve rod 13 and the inner side wall of the detection cavity 5.

[0032] The side of the positioning plate 10 near the detection lens 8 is arc-shaped. Several positioning plates 10 are placed in a ring at equal intervals. The positioning plates 10 are slidably mounted on the upper surface of the support plate 9. The lower surface of the detection lens 8 is close to the upper surface of the support plate 9 near the edge.

[0033] A sensor for detecting sugar content is fixedly installed inside the body 1. The detection lens 8 is made of prism material and is attached to the top of the sensor.

[0034] Working principle: First, the plant extract to be tested is dripped onto the detection lens 8, and the end cap 4 is placed on top to seal the detection chamber 5. The sensor detects the polysaccharide content of the extract on the detection lens 8. The detection lens 8 is placed on the support plate 9, and the positioning plate 10 is pushed to both sides. The positioning plate 10 pushes the sleeve rod 11 to move along the insertion rod 13, while squeezing the spring 12. Under the reaction force of the spring 12, the side of the positioning plate 10 is made to contact the outer side of the detection lens 8, thereby positioning the detection lens 8. The positioning plate 10 is pushed in the opposite direction to separate it from the position of the detection lens 8, and the detection lens 8 is moved upward, so that the detection lens 8 can be removed from the inside of the detection chamber 5, which facilitates the disassembly and replacement of the detection lens 8 and improves the performance of the device.

[0035] Example 2

[0036] like Figure 3and Figure 4 As shown, while all other parts are the same as in Example 1, the difference between this example and Example 1 is that:

[0037] A limiting frame 7 is slidably installed on the inner wall of the detection chamber 5 near the upper end, and a suction tube 6 is fixedly installed in the middle of the inner side of the limiting frame 7.

[0038] An air bladder 14 is fixedly connected to the upper end of the straw 6, and a water outlet pipe 15 is fixedly installed on the lower end of the straw 6.

[0039] The longitudinally moving limiting frame 7 drives the pipette 6 to move longitudinally above the detection lens 8, aligning the water outlet tube 15 on the pipette 6 with the position of the extractant. The air bag 14 is pinched and pressure is applied to draw the extractant into the inside of the pipette 6.

[0040] The water outlet pipe 15 and the suction pipe 6 are integrated components, and the lower end face of the water outlet pipe 15 corresponds to the center position of the detection lens 8.

[0041] Press the airbag 14 to squeeze the extract in the straw 6 onto the testing lens 8, making it easier for the user to drip the extract onto the testing lens 8.

[0042] An annular groove 16 is provided on the lower end face of the end cap 4, and an annular plate 17 is fixedly installed at the edge of the upper end face of the detection cavity 5.

[0043] Insert the annular plate 17 into the annular groove 16, and rotate the end cover 4 under the action of the thread, thereby installing the end cover 4 and the detection cavity 5 together, which facilitates the installation and removal of the end cover 4.

[0044] The annular plate 17 and the detection cavity 5 are an integral component, and the annular plate 17 is installed inside the annular groove 16 by threads.

[0045] One specific application of this embodiment is as follows: The longitudinally moving limiting frame 7 drives the pipette 6 to move longitudinally above the detection lens 8, aligning the water outlet tube 15 on the pipette 6 with the position of the extractant. The airbag 14 is pinched and pressure is applied to draw the extractant into the pipette 6. Then, the limiting frame 7 is placed inside the detection chamber 5, and the water outlet tube 15 on the pipette 6 is aligned with the center position of the detection lens 8. The airbag 14 is pressed to squeeze the extractant in the pipette 6 onto the detection lens 8, making it easier for the user to drip the extractant onto the detection lens 8, facilitating subsequent detection, reducing the impact of inaccurate dripping position on subsequent detection, and improving the performance of the device.
