Whether there is iodine solution in the medicine storage box 51 is observed through the first observation window 52. A proper amount of iodine solution is added to the inside of the sample container 66 through the medicine outlet pipe 53. Furthermore, the medicine outlet pipe 53 can be made of transparent hard plastic to facilitate the observation of the discharge of the reddish-brown iodine solution.

[0030] The stirring assembly 7 includes a connecting seat 71 and a stirring motor 72. The connecting seat 71 is fixedly arranged on the inner wall of the top end of the test box 1. The connecting seat 71 is sleeved on the outside of the bottom of the medicine outlet pipe 53. The inner wall of the connecting seat 71 is rotationally connected with a transmission pipe 73 through a sealed bearing. The inner wall of the transmission pipe 73 is slidably connected with the surface of the medicine outlet pipe 53. The surface of the transmission pipe 73 is fixedly provided with stirring blades 74. There are six stirring blades 74 and they are evenly distributed in a ring shape. The stirring motor 72 is fixedly arranged on the top end of the test box 1.

The inner wall of the gear ring 76 is fixedly connected with the surface of the top of the transmission pipe 73. When the stirring motor 72 is started, the stirring motor 72 will drive the driving gear 75 to rotate. The driving gear 75 drives the gear ring 76 to rotate. The gear ring 76 will drive the transmission pipe 73 to rotate. The transmission pipe 73 drives the stirring blades 74 to rotate. The stirring blades 74 will stir the iodine solution (mixed with iodine and water in a certain ratio) and the cream sample inside the sample container 66 to obtain a mixed solution.

[0031] The adjusting assembly 6 includes a lifting motor 61 and two guiding boxes 62. The lifting motor 61 is fixedly arranged on one side of the top end of the test box 1. The lifting motor 61 is a forward and reverse rotation motor. Both of the two guiding boxes 62 are fixedly arranged on the inner wall of the test box 1. The inner walls of both of the two guiding boxes 62 are slidably connected with a lifting frame 63. A lifting table 64 is fixedly arranged between the two lifting frames 63. A container groove 65 is opened at the top end of the lifting table 64. The inner wall of the container groove 65 is slidably connected with a sample container 66. The inner wall of one of the guiding boxes 62 is rotationally connected with a transmission lead screw 67 through a bearing. One end of the transmission lead screw 67 is fixedly connected with the transmission shaft of the lifting motor 61. The contact part between the transmission lead screw 67 and one of the lifting frames 63 is threadedly connected through a lead screw nut. First, add the cream sample into the sample container 66, and then move the sample container 66 to make the sample container 66 extend into the middle of the inside of the test box 1 and be stuck in the container groove 65.

[0032] The sample container 66 is sleeved on the outside of the stirring blades 74. A hemispherical heating block is fixedly arranged at the bottom of the lifting table 64. The lifting table 64 and the heating block are of an integrated structure. The lifting table 64, the heating block and the sample container 66 are all made of brass material. The hemispherical shape is beneficial for the flame of the combustion table 26 to heat the lifting table 64. The mixed solution inside the sample container 66 is heated through the heat-conducting lifting table 64 and the sample container 66 until the mixed solution boils. If it becomes milky after boiling and has a strong and fragrant smell, it indicates that this product is safe. If there is a smoking phenomenon after boiling and pungent residues are generated, it indicates that the mineral oil in the product exceeds the standard or it is filled with boride, and it may cause harm to the skin after use.

[0033] The inner wall at the bottom of the test chamber 1 is fixedly provided with a combustion table 26. The gas supply pipe of the combustion table 26 penetrates through the inner wall of the test chamber 1 and is placed outside the test chamber 1. The inner wall at the top of the test chamber 1 is fixedly provided with a second gas sensor module 16. The front of the test chamber 1 is fixedly provided with a current collector box 17, a second observation window 18 and a third observation window 19 respectively. The front of the test chamber 1 is hinged with a sealed chamber door 20. The front of the sealed chamber door 20 is fixedly provided with a handle 21 and a fourth observation window 22 respectively. Gas is supplied to the combustion table 26 through the gas supply pipe. The second observation window 18, the third observation window 19 and the fourth observation window 22 are provided for observing the position of the sample container 66.

[0034] A single-chip microcomputer is fixedly installed inside the current collector box 17. A first warning light 23 and a second warning light 24 are fixedly provided on one side of the current collector box 17 respectively. The first warning light 23, the second warning light 24, the first gas sensor module 15 and the second gas sensor module 16 are all electrically connected to the single-chip microcomputer. A switch panel 25 is provided on the front of the current collector box 17. If the antioxidant property of the facial cream is poor, then iodine tincture will remain in the mixed solution. The iodine tincture generates iodine vapor after heating. The first gas sensor module 15 and the second gas sensor module 16 can detect the concentration of the iodine vapor and transmit it to the single-chip microcomputer. A program is set inside the single-chip microcomputer. When the first gas sensor module 15 detects iodine vapor, the measured transmission value is greater than 0, and the single-chip microcomputer will activate the first warning light 23, and the first warning light 23 will light up to remind the user that there is iodine vapor in the space separated by the two activated carbon plates 11. That is to say, the filtering effect of the activated carbon plate 11 close to the test chamber 1 becomes poor and needs to be replaced in time. Further, after replacing the activated carbon plate 11 close to the test chamber 1 multiple times, the activated carbon plate 11 far from the test chamber 1 can be disassembled and installed in the positioning groove 12 close to the test chamber 1, and then a brand-new activated carbon plate 11 is inserted into the positioning groove 12 far from the test chamber 1 to prevent the iodine vapor in the space separated by the two activated carbon plates 11 from flowing into the room due to the poor filtering effect of the activated carbon plate 11 far from the test chamber 1 after long-term use. When the second gas sensor module 16 detects iodine vapor, the measured transmission value is greater than 0, and the single-chip microcomputer will activate the second warning light 24, and the second warning light 24 will light up to remind the user that there is iodine vapor inside the test chamber 1 and not to open the sealed chamber door 20, which is beneficial to maintaining the health of the user.

[0035] During use, four blowing fans are started through the switch panel 25. The blowing fans will generate airflows. The airflows sequentially pass through the dust-proof net 4 and the blow pipes 3 and enter the inside of the test chamber 1. Heating the iodine solution will generate iodine vapor. The airflows and the iodine vapor enter the air outlet pipe 8. The two activated carbon plates 11 adsorb the iodine vapor in the airflows to achieve iodine vapor filtration, avoiding the user from contacting the toxic iodine vapor and being safer.

[0036] When the activated carbon plate 11 needs to be replaced, remove the screws and pull the sealing plate 13 upward through the handle 14 to make the sealing plate 13 disengage from the air outlet pipe 8. Then, pull out the activated carbon plate 11 upward, slide the new activated carbon plate 11 into the positioning groove 12. When the activated carbon plate 11 moves downward, it squeezes the second rubber frame 10 and the first rubber frame 9, causing the second rubber frame 10 and the first rubber frame 9 to deform and closely adhere to the activated carbon plate 11. The second rubber frame 10 and the first rubber frame 9 seal the gap between the activated carbon plate 11 and the air outlet pipe 8. Then, move the sealing plate 13 downward to make the activated carbon plate 11 engage with the limit groove. Finally, screw in the screws to fix the sealing plate 13, completing the replacement of the activated carbon plate 11, which is very convenient. The silicone rubber material has excellent heat resistance and corrosion resistance, extending the service life of the second rubber frame 10 and the first rubber frame 9;

[0037] It should be emphasized that when testing the adaptability (antioxidant property) of the facial cream, first add the facial cream sample into the interior of the sample container 66, move the sample container 66 to make the sample container 66 extend into the middle inside the test box 1 and snap into the container slot 65. Then, start the lifting motor 61 through the switch panel 25. The lifting motor 61 drives the transmission lead screw 67 to rotate, and the transmission lead screw 67 drives the lifting frame 63, the lifting platform 64, and the sample container 66 to move upward, making the sample container 66 sleeved outside the stirring blade 74. Then, open the electric valve corresponding to the medicine outlet pipe 53 through the switch panel 25, and add an appropriate amount of iodine solution into the interior of the sample container 66 through the medicine outlet pipe 53. Start the stirring motor 72. The stirring motor 72 drives the driving gear 75 to rotate, the driving gear 75 drives the gear ring 76 to rotate, the gear ring 76 drives the transmission pipe 73 to rotate, and the transmission pipe 73 drives the stirring blade 74 to rotate. The stirring blade 74 stirs the iodine solution and the facial cream sample inside the sample container 66. After sufficient stirring, a mixed solution is obtained. If the mixed solution returns to a transparent state, it indicates that the facial cream has an antioxidant effect. If the mixed solution cannot be restored or even turns black, it indicates that the facial cream has no antioxidant function and may even exacerbate the oxidative aging of the skin.
