Description

Technical Field

[0001] This application relates to the technical field of fragrance retention test chambers, and in particular to a fragrance retention test chamber for testing the fragrance retention effect of fragrances. Background Technology

[0002] Fragrance is a complex mixture of various flavorings blended according to a specific formula, used to give products a unique aroma. Fragrances are widely used in many industries such as perfumes, personal care products, household cleaning products, food and beverages. According to their uses and characteristics, fragrances can be divided into different types, and multiple factors need to be considered during use to ensure the best effect.

[0003] Fragrance testing is a series of tests designed to evaluate the persistence, emission characteristics and stability of fragrances in different matrices. Among them, fragrance retention test is an important test. In the test, test paper is usually soaked in fragrance solution and then placed in a closed space. The fragrance will evaporate outward into the space. In the later testing, the closed space needs to be opened and the tester enters to conduct the test with a handheld tester.

[0004] Regarding the aforementioned technologies, the inventors discovered that when conducting fragrance retention tests, it is necessary to open a sealed space for personnel to enter and conduct the tests. However, when the sealed environment is opened, if the sealed space is too large when personnel enter and exit, air will enter and exit the sealed space, affecting the accuracy of the fragrance retention test in the sealed space. Utility Model Content

[0005] To overcome the current situation where fragrance retention testing requires opening a sealed space for personnel to enter, but opening the sealed environment too much when personnel enter and exit causes air to enter and exit, affecting the accuracy of the fragrance retention test in the sealed space, this application provides a fragrance retention test chamber for testing the fragrance retention effect of fragrances.

[0006] The fragrance retention test chamber provided in this application adopts the following technical solution:

[0007] A fragrance retention test chamber for testing the fragrance retention effect of fragrances includes a test chamber frame, an upper seal, and a lower seal. The test chamber frame includes a glass cover and an assembly insert. The upper and lower ends of the glass cover are connected and fixed with the assembly insert. A sampling screw ring is horizontally arranged on the vertical end face of the outer wall of the glass cover, and one end of the sampling screw ring passes through and is fixed to the outer wall of the glass cover. A sampling tube is horizontally inserted into the inside of the sampling screw ring, and a sampling port is opened through one end of the outer wall of the sampling tube. The other end of the outer wall of the sampling tube is provided with an external thread, and the external thread is threadedly connected to the sampling screw ring. The upper seal is inserted and assembled at the top of the glass cover, and the lower seal is inserted and assembled at the bottom of the glass cover.

[0008] By adopting the above technical solution, the fragrance to be tested is melted, and then the test strip is immersed in the fragrance solvent. The test strip is then hung in the hook of the upper seal, and the bottom of the glass frame of the test chamber is inserted and combined with the lower seal. Then, the upper seal with the test strip is inserted and combined with the top of the glass frame. After the test strip has released fragrance for a certain period of time, when the fragrance is tested, the sampling tube is rotated in the sampling screw ring of the glass frame and pulled out of the sampling screw ring. At this time, the gas in the glass frame contained in the sampling tube is tested for fragrance retention. This ensures that the air in the test chamber does not come into contact with the external environment during the test, thus ensuring the cleanliness of the air in the test chamber and the accuracy of the fragrance retention test in the closed space.

[0009] Optionally, sealing plates are fixed at both ends of the sampling tube, and the outer diameter of the sealing plates is larger than the inner diameter of the sampling screw ring.

[0010] By adopting the above technical solution, the sealing plates fixed at both ends of the sampling tube can seal the sampling screw rings at the sliding ends of the sampling tube, preventing the air in the test chamber frame from exchanging with the outside, thus avoiding affecting the cleanliness of the air in the test chamber frame and the accuracy of the fragrance retention test in the closed space.

[0011] Optionally, both the upper and lower sealing components include a horizontal plate, with a connecting frame vertically fixed on the horizontal end face of the horizontal plate near the glass frame cover, and the connecting frame is inserted into the assembly frame.

[0012] By adopting the above technical solution, the connecting frames set on the horizontal plates of the upper and lower seals are inserted into the assembly frames at the ends of the glass cover, thus completing the rapid assembly of the upper and lower seals with the glass cover.

[0013] Optionally, a sealing gasket is vertically fixed on the outer wall of the connecting frame.

[0014] By adopting the above technical solution, the sealing gasket fixed to the outer wall of the connecting frame seals the gap between the connecting frame and the assembled frame, effectively ensuring the airtightness of the connecting frame and the assembled frame during insertion.

[0015] Optionally, a sliding groove is provided on the horizontal plate, which slides horizontally through the front and rear vertical end faces. A push-pull slide plate is horizontally slidably installed on both the front and rear sides of the sliding groove, and a screw hole plate is vertically fixed on the horizontal end face of the push-pull slide plate away from the glass frame cover.

[0016] By adopting the above technical solution, a push-pull slide plate is slidably installed in the groove opened on the horizontal plate. The opening and closing of the sealed space of the test chamber frame is controlled by the push-pull slide plate moving laterally in the groove of the horizontal plate, which facilitates the release of air from the test chamber frame after the subsequent test.

[0017] Optionally, a double-headed motor is horizontally fixed on the horizontal end face of the side of the horizontal plate away from the glass frame cover, and the output ends of the double-headed motor are horizontally fixedly connected to screws, with the screw threads passing through the screw hole plate.

[0018] By adopting the above technical solution, the push-pull slide plate is controlled to move laterally in the groove in the horizontal plate. When the sealed space of the test chamber frame is controlled to open and close, the double-head motor is started to drive the screw to rotate. The screw thread drives the screw hole plate on the push-pull slide plate to move laterally in the groove in the horizontal plate, thereby controlling the opening and closing of the sealed space of the test chamber frame.

[0019] Optionally, a hook is vertically fixed to the middle of the horizontal end face of the upper sealing plate near the glass frame cover.

[0020] By adopting the above technical solution, the hook is designed for hanging test strips later.

[0021] Optionally, multiple supports are vertically fixed to the horizontal end face of the lower sealing plate away from the glass frame.

[0022] By adopting the above technical solution, multiple support pillars on the horizontal plate of the lower seal are used to support the lower seal and ensure the stability of the support.

[0023] In summary, this application includes at least one of the following beneficial technical effects: the fragrance to be tested is melted, then the test strip is immersed in the fragrance solvent, then the test strip is hung in the hook of the upper seal, then the bottom of the glass frame of the test chamber is inserted and combined with the lower seal, then the upper seal with the test strip is inserted and combined with the top of the glass frame, and after the test strip has released for a certain period of time, when the fragrance is tested, the sampling tube is rotated in the sampling screw ring of the glass frame, and the sampling tube is pulled out of the sampling screw ring. At this time, the gas in the glass frame contained in the sampling tube is tested for fragrance retention. Thus, the air in the test chamber is not in contact with the external environment during the test, ensuring the cleanliness of the air in the test chamber and the accuracy of the fragrance retention test in the closed space.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a fragrance retention test chamber for testing the fragrance retention effect of fragrances. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A fragrance retention test chamber for testing the fragrance retention effect of fragrances includes a test chamber frame 1, an upper seal 2, and a lower seal 3. The test chamber frame 1 includes a glass frame cover 11 and an assembly insert frame 12. The upper and lower ends of the glass frame cover 11 are connected and fixed with the assembly insert frame 12. A sampling screw ring 13 is horizontally arranged on the vertical end face of the outer wall of the glass frame cover 11, and one end of the sampling screw ring 13 passes through and is fixed to the outer wall of the glass frame cover 11. A sampling tube 14 is horizontally inserted into the inside of the sampling screw ring 13, and a sampling port 142 is opened through the outer wall of the sampling tube 14. The other end of the outer wall of the sampling tube 14 is provided with an external thread 141, and the external thread 141 is threadedly connected to the sampling screw ring 13. The upper seal 2 is inserted and assembled on the top of the glass frame cover 11, and the lower seal 3 is inserted and assembled on the bottom of the glass frame cover 11.

[0032] By adopting the above technical solution, the fragrance to be tested is melted, and then the test strip is immersed in the fragrance solvent. The test strip is then hung in the hook 21 of the upper seal 2. The bottom of the glass frame 11 of the test chamber frame 1 is then inserted and combined with the lower seal 3. The upper seal 2 with the test strip is then inserted and combined with the top of the glass frame 11. After the test strip has released its fragrance for a certain period of time, when the fragrance test is performed, the sampling tube 14 is rotated in the sampling screw ring 13 of the glass frame 11. The sampling tube 14 is pulled out of the sampling screw ring 13. At this time, the gas in the glass frame 11 contained in the sampling tube 14 is tested for fragrance retention. This ensures that the air in the test chamber frame 1 does not come into contact with the external environment during the test, thus ensuring the cleanliness of the air in the test chamber frame 1 and the accuracy of the fragrance test in the closed space.

[0033] Reference Figure 3The sampling tube 14 is fixed with sealing plates 143 at both ends, and the outer diameter of the sealing plates 143 is larger than the inner diameter of the sampling screw ring 13. The sealing plates 143 fixed at both ends of the sampling tube 14 can seal the sampling screw ring 13 at both ends of the sliding sampling tube 14, so as to prevent the air in the test chamber frame 1 from exchanging with the outside, which would affect the air cleanliness in the test chamber frame 1 and the accuracy of the fragrance retention test in the closed space.

[0034] Reference Figure 4 and Figure 5 Both the upper sealing member 2 and the lower sealing member 3 include a horizontal plate 4. A connecting frame 7 is vertically fixed on the horizontal end face of the horizontal plate 4 near the glass frame cover 11, and the connecting frame 7 is inserted into the assembly frame 12. The connecting frame 7 on the horizontal plate 4 of the upper sealing member 2 and the lower sealing member 3 is inserted into the assembly frame 12 at the end of the glass frame cover 11, completing the rapid assembly of the upper sealing member 2 and the lower sealing member 3 with the glass frame cover 11. A sealing gasket 8 is vertically fixed on the outer wall of the connecting frame 7. The sealing gasket 8 fixed on the outer wall of the connecting frame 7 seals the gap between the connecting frame 7 and the assembly frame 12, effectively ensuring the airtightness of the connecting frame 7 and the assembly frame 12 during insertion.

[0035] Reference Figure 4 and Figure 5 A horizontal sliding groove 41 is provided on the horizontal plate 4, extending horizontally through the front and rear vertical end faces. Push-pull slide plates 5 are horizontally slidably installed on both sides of the groove 41. Screw holes 51 are vertically fixed on the horizontal end face of the push-pull slide plates 5 away from the glass frame 11. During use, the push-pull slide plates 5, slidably installed in the groove 41 on the horizontal plate 4, move laterally within the groove 41, controlling the opening and closing of the sealed space of the test chamber frame 1, facilitating the release of air from the test chamber frame 1 after subsequent tests. A double-headed motor 6 is horizontally fixed on the horizontal end face of the horizontal plate 4 away from the glass frame 11. Screws 61 are horizontally fixedly connected to the output ends of the double-headed motor 6, and the screws 61 are threaded through and assembled in the screw holes 51. When the push-pull slide plate 5 moves laterally in the slide groove 41 in the horizontal plate 4, and controls the opening and closing of the sealed space of the test chamber frame 1, the double-head motor 6 is started to drive the screw 61 to rotate. The screw drive on the screw hole plate 51 of the push-pull slide plate 5 drives the push-pull slide plate 5 to move laterally in the slide groove 41 in the horizontal plate 4, thereby controlling the opening and closing of the sealed space of the test chamber frame 1.

[0036] Reference Figure 4 A hook 21 is vertically fixed to the middle of the horizontal end face of the upper sealing plate 4 near the glass frame cover 11. The hook 21 is used to hang test strips later.

[0037] Reference Figure 5 Multiple support columns 31 are vertically fixed on the horizontal end face of the lower sealing member 3's horizontal plate 4 away from the glass frame cover 11. The multiple support columns 31 on the lower sealing member 3's horizontal plate 4 are used to support the lower sealing member 3 and ensure the stability of the support.

[0038] The implementation principle of a fragrance retention test chamber for detecting the fragrance retention effect of a fragrance according to an embodiment of this application is as follows: The fragrance to be tested is melted, and then test strips are immersed in the fragrance solvent. The test strips are then hung in the hooks 21 of the upper seal 2. The connecting frames 7 on the horizontal plates 4 of the upper seal 2 and the lower seal 3 are inserted into the assembly frames 12 at the end of the glass frame 11, completing the rapid assembly of the upper seal 2 and the lower seal 3 with the glass frame 11. Then, the bottom of the glass frame 11 of the test chamber frame 1 is inserted and combined with the lower seal 3. Finally, the upper seal 2 with the test strips is inserted and combined with the top of the glass frame 11. After the fragrance has been released for a certain period of time, when the fragrance retention test is performed, the sampling tube 14 is rotated in the sampling screw ring 13 of the glass frame cover 11. The sampling tube 14 is pulled out of the sampling screw ring 13. At this time, the gas in the glass frame cover 11 contained in the sampling tube 14 is tested for fragrance retention. The sliding plate 5 is controlled to move laterally in the slide groove 41 in the horizontal plate 4. When the sealed space of the test chamber frame 1 is controlled to open and close, the double-head motor 6 is started to drive the screw 61 to rotate. The screw hole plate 51 on the sliding plate 5 drives the sliding plate 5 to move laterally in the slide groove 41 in the horizontal plate 4, controlling the opening and closing of the sealed space of the test chamber frame 1, which is used to release the air in the test chamber frame 1 after the later test.

[0039] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
