Description

Technical Field

[0001] This utility model relates to the field of flower testing equipment technology, and in particular to an instrument for testing the dryness of preserved flowers. Background Technology

[0002] Preserved flowers are dried flowers made from fresh-cut flowers through a series of complex processes including dehydration, decolorization, drying, and dyeing. Their appearance and texture are almost indistinguishable from fresh flowers, and they can maintain their freshness for a long time. They are widely used in floral design, home decoration, and commercial activities. In the production process of preserved flowers, the degree of drying is a key factor affecting their quality and shelf life. If not dried sufficiently, preserved flowers are prone to mold and spoilage, shortening their shelf life; if over-dried, they will lose their original color and texture, reducing their ornamental value.

[0003] When testing the dryness of preserved flowers, the humidity inside the instrument can interfere with the accuracy of the test results. Preserved flowers retain a certain degree of hygroscopicity after drying. If the humidity inside the test chamber is too high, water vapor in the air is easily adsorbed by the surface of the preserved flower sample, thus affecting the judgment of the true dryness of the preserved flower. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that the humidity inside the instrument interferes with the accuracy of the test results when testing the dryness of preserved flowers. Preserved flowers still retain a certain degree of hygroscopic properties after drying. If the humidity inside the test chamber is too high, water vapor in the air is easily adsorbed by the surface of the preserved flower sample, thus affecting the judgment of the true dryness of the preserved flowers. Therefore, this invention proposes an instrument for testing the dryness of preserved flowers.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figures 1-6 As shown, this utility model provides a technical solution: a dried flower drying degree testing instrument, including a drying degree testing component 1, a sealing component 2 and a vacuum component 3, and an installation / removal component 4 and a positioning component 5 inside the drying degree testing component 1. The drying degree testing component 1 includes a testing chamber 101 and a near-infrared spectrometer 105. The vacuum component 3 includes a limiting ring 301, which is fixedly installed inside the testing chamber 101. A filter element 302 is installed inside the limiting ring 301. A connecting pipe 306 is connected to the side of the testing chamber 101, and a miniature vacuum pump 307 is connected to one end of the connecting pipe 306. The inner surface of the testing chamber 101... The part is provided with a limiting plate 304, and a rotating shaft 305 passes through the inside of the limiting plate 304. A baffle 303 is provided on the filter element 302. The limiting plate 304 is connected to the baffle 303. A connecting pipe 306 is provided on the side of the filter element 302 and passes through the side of the test box 101. A test cavity 104 is opened on the side of the test box 101. A door 102 is installed on the side of the test box 101. A hinge is provided between the test box 101 and the door 102. The sealing assembly 2 includes a sealing frame 201, which is provided on the side of the test box 101. A sealing gasket 202 is provided on the outside of the door 102. Support legs 103 are provided at the four corners of the bottom of the test box 101.

[0022] In this embodiment, by inserting the filter element 302 inside the limiting ring 301, one end of the connecting pipe 306 is connected to the filter element 302. Then, the limiting plate 304 is rotated by the rotating shaft 305, causing the limiting plate 304 to connect with the baffle 303. This facilitates the installation of the filter element 302 and eliminates the need for laborious maintenance and replacement using a large number of bolts, improving the maintenance convenience of the filter element 302. During testing, the micro vacuum pump 307 operates, and the connecting pipe 306 connects to the detection chamber 104, which helps to extract the air inside the detection chamber 104, creating a negative pressure environment inside the detection chamber 104. This reduces the humidity inside the detection chamber 104, thereby reducing the impact on the preserved flower. The detection process reduces interference and improves accuracy and reliability. A continuous spectrum emitted by the near-infrared spectrometer 105 illuminates the preserved flower sample. Some light is absorbed by the moisture in the sample, while the remaining light is captured by the spectrometer after reflection or transmission. The data processing module analyzes the intensity and position of the absorption peaks to calculate the sample's moisture content, thus facilitating the detection of dryness. During detection, a hinge ensures that the detection chamber 101 and door 102 are closed, connecting the sealing frame 201 and sealing gasket 202. This improves the sealing performance of the detection chamber 101 when closed, reducing the entry of impurities and moisture into the detection chamber 104 through gaps, further ensuring the accuracy of the detection results.

[0023] Example 2: Figures 1-6 As shown, the installation and disassembly assembly 4 includes a mounting block 401, which is located on the top of the near-infrared spectrometer 105. The inside of the detection box 101 is provided with a mounting groove 402, and the mounting block 401 is inserted into the mounting groove 402. An insert plate 403 passes through the inside of the mounting block 401, and a fastening bolt 404 is threaded into the inside of the insert plate 403. A placement plate 106 is provided inside the detection cavity 104. The positioning assembly 5 includes a first sliding groove 501 and a second sliding groove 502, which are respectively located at the top ends of the placement plate 106. A movable frame 505 is symmetrically slidably installed inside the first sliding groove 501 and the second sliding groove 502. A spring 506 is connected to the bottom of the movable frame 505, and a positioning plate 507 is connected to the bottom of the spring 506. A silicone pad 508 is provided at the bottom of the positioning plate 507. A plurality of through holes 503 are provided on the first sliding groove 501, and a pin 504 is provided inside one of the through holes 503.

[0024] In this embodiment, by inserting the mounting block 401 into the mounting groove 402, and then using the insert plate 403 to pass through the mounting block 401, followed by using the fastening bolt 404 threaded through the insert plate 403, it is beneficial to limit the position of the near-infrared spectrometer 105, facilitate the disassembly and maintenance of the near-infrared spectrometer 105, ensure the normal use of the near-infrared spectrometer 105, and thus ensure the detection accuracy. By placing the preserved flower sample inside the placement plate 106, the elasticity of the spring 506 causes the silicone pad 508 to contact the sample, which is beneficial to the positioning of the sample. The silicone pad 508 provides flexible contact, reducing the occurrence of sample damage. By moving the movable frame 505 inside the first slide groove 501 and the second slide groove 502, it is beneficial to adjust the position of the silicone pad 508. Then, using the pin 504 to pass through the through hole 503, it is beneficial to limit the position of the movable frame 505, facilitate adjustment according to the size of the sample, and reduce the displacement of the sample during the detection process.

[0025] The working principle of this embodiment is as follows: In use, the preserved flower sample is first placed inside the placement plate 106. The elasticity of the spring 506 causes the silicone pad 508 to contact the sample, facilitating sample positioning. The silicone pad 508 provides flexible contact, reducing the possibility of sample damage. The movable frame 505 moves within the first and second slide grooves 501 and 502, allowing for adjustment of the silicone pad 508's position. Subsequently, a pin 504 passes through the through hole 503, limiting the movement of the movable frame 505. Adjusted according to the sample size, and then with the hinge, the detection chamber 101 and the door 102 are closed, thereby connecting the sealing frame 201 and the sealing gasket 202. This improves the sealing performance of the detection chamber 101 when closed, reducing the entry of impurities and moisture into the detection chamber 104 through gaps. Subsequently, a micro vacuum pump 307 operates, and the connecting pipe 306 connects to the detection chamber 104 to extract air from inside the detection chamber 104, creating a negative pressure environment inside the detection chamber 104 and reducing the humidity inside the detection chamber 104. The near-infrared spectrometer 105 emits a continuous spectrum, which is then applied to the preserved flower sample. Part of the light is absorbed by the moisture in the sample, while the remaining light is reflected or transmitted and captured by the spectrometer. The data processing module analyzes the intensity and position of the absorption peaks to calculate the moisture content of the sample, thus facilitating the detection of dryness. When maintenance of the filter element 302 is required, it is inserted into the limiting ring 301, connecting one end of the connecting tube 306 to the filter element 302. Then, the limiting plate 304 is rotated using the rotating shaft 305. The connection between the limiting plate 304 and the baffle 303 facilitates the installation of the filter element 302, eliminating the need for laborious maintenance and replacement of the filter element 302 using a large number of bolts. When maintenance of the near-infrared spectrometer 105 is required, the mounting block 401 is inserted into the mounting groove 402, and then the insert plate 403 is inserted through the mounting block 401. Finally, the fastening bolt 404 is threaded through the insert plate 403, which facilitates the limiting of the near-infrared spectrometer 105 and the disassembly and maintenance of the near-infrared spectrometer 105.

[0026] The detection box 101, near-infrared spectrometer 105, and miniature vacuum pump 307 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the detection box 101, near-infrared spectrometer 105, and miniature vacuum pump 307 will not be explained in detail.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
