Description

Technical Field

[0001] This utility model relates to the field of testing device technology, and in particular to an accelerated testing device for the photothermal stability of fragrances. Background Technology

[0002] The accelerated photothermal stability test device for fragrances is a professional device used to evaluate the stability and lifespan of fragrances under light and high temperature conditions. Its design needs to take into account the coupled effects of multiple factors such as light, heat, and humidity in order to simulate the deterioration process in a real storage environment.

[0003] However, the existing device has the following problems: the device tests the fragrance by simulating a high-temperature environment. After the test is completed, the container holding the fragrance is at a high temperature. It is usually cooled naturally, but the cooling process takes a long time. Therefore, it may be affected by external factors, which may reduce the accuracy of the test structure. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where devices test fragrances in a simulated high-temperature environment. After the test, the container holding the fragrance is at a high temperature and typically cools down naturally, which takes a long time and may be affected by external factors, thus reducing the accuracy of the test results. Therefore, this invention proposes an accelerated testing device for the photothermal stability of fragrances.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An accelerated testing device for the photothermal stability of fragrances includes a housing. Both inner walls of the housing are fixedly equipped with lamp panels for simulating illumination and cameras for monitoring during the test. Multiple LEDs are installed on the adjacent side of the two lamp panels. The interior of the housing is equipped with a fixing mechanism for securing containers containing fragrances. The top of the housing is equipped with a sealing cover. Both the cover and the housing are equipped with the same heat dissipation mechanism, which includes a first shielding mechanism and a second shielding mechanism for sealing.

[0007] In one possible design, the fixing mechanism includes a top plate, a bottom plate, and a threaded post. The bottom of the bottom plate is fixedly connected to the center of the bottom inner wall of the box. The top plate is slidably disposed on the inner wall of the box and located directly above the bottom plate. The bottom end of the threaded post is threaded through the top center of the top plate and rotatably connected to the top center of the bottom plate. A rotating handle is fixedly connected to the top end of the threaded post.

[0008] In one possible design, the heat dissipation mechanism includes two air outlets, two primary filters, two air inlet channels, two cooling fans, and two secondary filters. The top cover has two air inlet holes. The outer sides of the two air inlet channels are fixedly connected to the inner walls of the two air inlet holes, respectively. The two cooling fans are fixedly mounted on the inner walls of the two air inlet channels by bolts. The two secondary filters are fixedly mounted on the top of the two air inlet channels by bolts. The two air outlets are respectively located on the bottom sides of the same housing. The two primary filters are fixedly mounted on the inner walls of the two air outlets by bolts.

[0009] In one possible design, the first shielding mechanism includes four No. 1 baffles, two connecting rods, a bidirectional lead screw, two No. 1 connecting blocks, and a motor. The tops of the two No. 1 connecting blocks are fixedly connected to the bottom of the housing. The two ends of the bidirectional lead screw are rotatably connected to the sides of the two No. 1 connecting blocks near each other via bearings. One side of the motor is fixedly mounted on one side of the No. 1 connecting block by bolts, and the output shaft rotatably passes through one side of the No. 1 connecting block and is fixedly connected to one end of the bidirectional lead screw. The two connecting rods are threaded onto the same bidirectional lead screw. One side of each of the four No. 1 baffles is fixedly connected to the two ends of the two connecting rods. The four No. 1 baffles are located at the bottom of the two air outlets.

[0010] In one possible design, the second shielding mechanism includes two second baffles, a push plate, an electric telescopic rod, and a second connecting block. The bottom of the second connecting block is fixedly connected to the top of the top cover, one side of the second connecting block is fixedly connected to the fixed end of the electric telescopic rod, the telescopic end of the electric telescopic rod is fixedly connected to the center of one side of the push plate, and both sides of one side of the push plate are fixedly connected to one side of the two second baffles respectively. The other sides of the two second baffles slide through one side of the two air inlet channels and shield and seal the air inlet channels.

[0011] In one possible design, the top cover is rotatably provided with retaining rings on both sides, and the box body is fixedly connected with retaining blocks that are adapted to the retaining rings on both sides, with the two retaining rings respectively fitted onto the two retaining blocks.

[0012] In one possible design, a heating frame for heating the box is fixedly fitted on the outside of the box, a heating tube is provided inside the heating frame, and a temperature sensor is provided on the top of the top cover.

[0013] In one possible design, the bottom four corners of the heating frame are fixedly connected to support columns for support, and the bottom of each of the four support columns is fixedly connected to an anti-slip pad.

[0014] In one possible design, sliders are fixedly connected to both sides of the top plate, and the inner walls of the front and rear sides of the box are provided with grooves that are adapted to the sliders, with the two sliders slidably connected to the two grooves respectively.

[0015] In this application, during use, the container holding the fragrance is placed on the bottom plate inside the chamber. The rotating handle at the top of the threaded post is rotated. Because the bottom of the threaded post is rotatably connected to the center of the top of the bottom plate, and the thread passes through the center of the top of the top plate, the top plate moves up and down along the inner wall of the chamber under the action of the thread and the sliding limit of the slider and the groove, thus fixing the fragrance container between the top and bottom plates. After the top cover is fixed with a retaining ring and a retaining block, the controller turns on multiple LEDs on the light panel. The light panel is fixed to the inner walls of both sides of the chamber, and the LEDs emit light to simulate a lighting environment. The heating frame is fixedly fitted on the outside of the chamber, and its internal heating tubes generate heat to heat the chamber, simulating different temperature environments. A temperature sensor monitors the temperature inside the chamber in real time and transmits the temperature data to the controller. The controller adjusts the heating power of the heating frame according to the preset test requirements. Simultaneously, cameras are fixed to the inner walls of both sides of the chamber to monitor the state of the fragrance during the test. The monitoring screen displays the information. The data is transmitted to the controller via a line, allowing staff to monitor the test status in real time using external devices. If the temperature inside the chamber becomes too high after the test, the controller activates the electric telescopic rod, which moves the push plate, thereby moving the two second-order baffles. These baffles slide within the air inlet channel, opening it. The controller then activates the motor, which drives a bidirectional lead screw. The two connecting rods on the lead screw move away from each other, moving the four first-order baffles to open the air outlet. The airflow can be controlled by manipulating the electric telescopic rod and the motor. The controller then activates the cooling fan, which draws outside air into the chamber through the air inlet channel and simultaneously exhausts hot air from the chamber through the air outlet. After cooling is complete, the fragrance is removed, and testing equipment (such as a spectrophotometer and GC-MS) is used to analyze changes in sample composition and compare the results with initial data to assess the fragrance's stability (e.g., changes in transmittance and component content).

[0016] The beneficial effects of this utility model are as follows:

[0017] In this invention, the heat inside the chamber can be effectively dissipated through the operation of the cooling fan and the coordination of the air inlet and outlet vents, reducing the risk of injury to staff when opening the chamber and lowering safety hazards. It also reduces the heat dissipation time and ensures the accuracy of the test results. Meanwhile, the first and second shielding mechanisms can control the air inlet and outlet volumes and the sealing, further optimizing the heat dissipation effect. By rotating the threaded column to move the top plate up and down, the container holding the fragrance can be stably fixed, preventing the container from moving or tipping over during the test and ensuring the smooth progress of the test.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Reference Figures 1-5 A testing device includes a housing 1, a fixing mechanism, a heat dissipation mechanism, a first shielding mechanism, a second shielding mechanism, etc. The device is designed to simulate different photothermal environments to conduct accelerated photothermal stability tests on fragrances, and also has functions such as heat dissipation and sealing to ensure the accuracy and stability of the testing process.

[0027] The housing 1 serves as the main structure of the device. Light panels 8 and cameras 7 are fixedly installed on the inner walls of both sides. The light panels 8 are used to simulate illumination, and multiple LED lights are installed on the adjacent side. The cameras 7 are used to monitor the test. A heating frame 2 is fixedly fitted onto the outer side of the housing 1. Heating tubes are installed inside the heating frame 2 to heat the housing 1 and simulate different temperature environments. Support columns 3 are fixedly connected to the four corners of the bottom of the heating frame 2, and anti-slip pads are fixedly connected to the bottom of each of the four support columns 3, providing support and anti-slip properties. A top cover 4 is installed on the top of the housing 1 to seal it. Retaining rings 6 are rotatably installed on both sides of the top cover 4. Locking blocks 14 that match the retaining rings 6 are fixedly connected to both sides of the housing 1. The two retaining rings 6 are respectively fitted onto the two locking blocks 14, enabling a detachable connection between the top cover 4 and the housing 1.

[0028] The fixing mechanism is set inside the box 1, including a top plate 9, a bottom plate 10, and a threaded post 12. The bottom of the bottom plate 10 is fixedly connected to the center of the bottom inner wall of the box 1. The top plate 9 is slidably set on the inner wall of the box 1 and located directly above the bottom plate 10. The bottom end of the threaded post 12 is threaded through the center of the top of the top plate 9 and rotatably connected to the center of the top of the bottom plate 10. A rotating handle is fixedly connected to the top of the threaded post 12. By rotating the rotating handle, the threaded post 12 is rotated, thereby causing the top plate 9 to move up and down to fix the container for storing fragrance. Slider blocks are fixedly connected to both sides of the top plate 9. The front inner wall and the rear inner wall of the box 1 are provided with grooves 11 that are adapted to the sliders. The two sliders are slidably connected to the two grooves 11 respectively to ensure the stability of the top plate 9 moving up and down.

[0029] The heat dissipation mechanism includes two air outlets 13, two primary filters 20, two air inlet channels 21, two cooling fans 27, and two secondary filters 26. Two air inlet holes are provided on the top cover 4. The outer sides of the two air inlet channels 21 are fixedly connected to the inner walls of the two air inlet holes. The two cooling fans 27 are bolted to the inner walls of the two air inlet channels 21 to draw outside air into the housing 1. The two secondary filters 26 are bolted to the top of the two air inlet channels 21 to prevent dust and other impurities from entering the housing 1. The two air outlets 13 are respectively located on both sides of the bottom of the same housing 1. The two primary filters 20 are bolted to the inner walls of the two air outlets 13 to prevent dust from being discharged from the housing 1. After testing, the cooling fans, along with the air inlet and outlet holes 13, dissipate heat from inside the housing 1, reducing the safety hazards associated with opening the housing 1.

[0030] The first shielding mechanism includes four No. 1 baffles 15, two connecting rods 16, a bidirectional lead screw 17, two No. 1 connecting blocks 18, and a motor 19. The tops of the two No. 1 connecting blocks 18 are fixedly connected to the bottom of the housing 1. The two ends of the bidirectional lead screw 17 are rotatably connected to the sides of the two No. 1 connecting blocks 18 close to each other via bearings. One side of the motor 19 is fixedly mounted on one side of the No. 1 connecting block 18 by bolts, and the output shaft rotates through one side of the No. 1 connecting block 18 and is fixedly connected to one end of the bidirectional lead screw 17. The two connecting rods 16 are threaded onto the same bidirectional lead screw 17. One side of the four No. 1 baffles 15 is fixedly connected to the two ends of the two connecting rods 16. The four No. 1 baffles 15 are located at the bottom of the two air outlets 13. The motor 19 drives the bidirectional lead screw 17 to rotate, causing the two connecting rods 16 to move closer or further apart, thereby moving the four No. 1 baffles 15 to open or close the air outlets 13. The rubber gaskets on the No. 1 baffles 15 ensure their sealing.

[0031] The second shielding mechanism includes two second baffles 22, a push plate 23, an electric telescopic rod 24, and a second connecting block 25. The bottom of the second connecting block 25 is fixedly connected to the top of the top cover 4. One side of the second connecting block 25 is fixedly connected to the fixed end of the electric telescopic rod 24. The telescopic end of the electric telescopic rod 24 is fixedly connected to the center of one side of the push plate 23. One side of the push plate 23 is fixedly connected to one side of the two second baffles 22 respectively. The other side of the two second baffles 22 slides through one side of the two air inlet channels 21 respectively. By extending and retracting the electric telescopic rod 24, the push plate 23 is moved, which in turn moves the two second baffles 22. The rubber pads on the second baffles 22 also achieve the shielding and sealing of the air inlet channels 21.

[0032] This application can be used in the field of fragrance testing devices, or in other fields applicable to this application.

[0035] A temperature sensor 5 is installed on the top of the top cover 4 to monitor the temperature inside the chamber 1 in real time, so as to adjust the heating power of the heating frame 2 according to the test requirements.

[0036] However, as is well known to those skilled in the art, the working principles and wiring methods of the heating element, temperature sensor 5, camera 7, LED light, motor 19, electric telescopic rod 24, and cooling fan 27 are commonplace and belong to conventional methods or common knowledge, so they will not be described in detail here.
