[0046] A detection method for cosmetics based on ex vivo cells includes the following steps:

[0047] S1. When it is necessary to test whether cosmetics contain heavy metals, firstly, put silver powder and baking soda into the two storage tanks 102 respectively, then pour an appropriate amount of cosmetic lotion into the two mixing boxes 115. After that, use the electric telescopic rod 106 and the connecting plate 107 to drive the first concave block 105 to move, so that the silver powder and baking soda in the two storage tanks 102 fall into the two mixing boxes 115 respectively.

[0048] S2. Next, using the cooperation of motor 112, pulley 111, belt, round rod 120 and rotating rod 110, drive the corresponding stirring rod 121 to rotate, mix the silver powder with the cosmetic emulsion, and mix the baking soda powder with the cosmetic powder. Then turn off motor 112, let it stand for more than ten minutes, and observe.

[0049] S3. When it is necessary to pre-treat the mixture after testing, use a tool to take out the mixture from the mixing box 115 and put it into the placement tray 204. Then place it inside the two second concave blocks 203, install the sealing plate 202, and then use the control switch 211 and the battery 212 to simultaneously turn on the two ultraviolet lamps 205 for disinfection.

[0050] In this invention, when it is necessary to test whether cosmetics contain heavy metals, firstly, the entire device is moved to the desired position, then the latch is opened, and the cover plate 3 is removed. At this time, the moving cover plate 3 will cause the two sealing gaskets 4 to move out of the two storage tanks 102 respectively. Then, silver powder and baking soda are put into the two storage tanks 102 respectively. Next, the cover plate 3 is used to move the two sealing gaskets 4 back to the initial position, and the cover plate 3 is fixed to the housing 101 with the lock hole. Then, the second hand-tightening screw 6 is removed, and then the L-shaped plate 5 can be removed from the housing 101. Then, an appropriate amount of cosmetic lotion is poured into the two mixing boxes 115. Then, the controller 123 is started. At this time, the started controller 123 will directly control the electric extension When the telescopic rod 106 is activated, its telescopic end will move the connecting plate 107 towards the first hollow block 104. The moving connecting plate 107 will then move the first concave block 105 slowly into the first hollow block 104. When one end of the first concave block 105 can no longer move, the controller 123 will directly control the telescopic rod 106 to close. Simultaneously, the two through holes on the first concave block 105 will connect with the outlets of the two discharge pipes 103. At this point, the silver powder and baking soda powder inside the two storage tanks 102 will fall under their own weight directly into the two mixing boxes 115. The motor 112 will then be activated. 12, with the cooperation of two pulleys 111 and the belt, directly drives two rotating rods 110 to rotate simultaneously. The rotating rods 110, through the cooperation of their respective hand-tightening bolt rods 119, threaded grooves 114, second hollow blocks 122, ring blocks 116, and anti-slip pads 117, drive their corresponding round rods 120 to rotate. The rotating round rods 120 then drive their connected stirring rods 121 to rotate. Under the action of the stirring rods 121, the silver powder and the cosmetic emulsion are thoroughly mixed. After waiting for about ten minutes, the mixture can be observed using two testing methods. If the mixture in the stirring box 115 containing the silver powder changes... If the color is positive, the cosmetic contains heavy metals; otherwise, it does not. If the mixture in the mixing box 115 turns gray or black after being placed in baking soda, the cosmetic contains heavy metals; otherwise, it does not. Dual or multiple detection methods can improve the accuracy and efficiency of the cosmetic testing device. When the tested mixture needs to be cleaned up, and to prevent harm during later centralized processing, pretreatment is required. In this case, the motor 112 is turned off, and all the hand-tightened bolts 119 are removed from their corresponding threaded grooves 114. Then, the mixing box 115 can be moved to disengage the corresponding round rods 120 from their corresponding rotating rods 110.Next, using tools, the mixture on the mixing box 115 is removed and transferred to the placement tray 204. Once almost all the mixture from both mixing boxes 115 has been removed and transferred to the placement tray 204, the tray 204 is placed directly between the two second concave blocks 203. Then, using the first hand-tightened screw 206, the sealing plate 202 is installed at the opening of the disinfection box 201. Afterwards, with the assistance of the battery 212, the two ultraviolet lamps 205 are activated using the control switch 211. The light emitted by the two activated ultraviolet lamps 205 directly disinfects the tested cosmetic mixture, effectively preventing harm to staff during later centralized processing.

[0051] Among them, the electric telescopic pole 106, motor 112, controller 123, ultraviolet lamp 205, control switch 211 and storage battery 212 are all existing technologies, and their components and operating principles are all publicly available technologies, so they will not be explained in detail here.

[0052] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

When it is necessary to test whether cosmetics contain heavy metals, firstly, put silver powder and baking soda into the two storage tanks (102) respectively, then pour an appropriate amount of cosmetic lotion into the two mixing boxes (115), and then use the electric telescopic rod (106) and connecting plate (107) to drive the first concave block (105) to move, so that the silver powder and baking soda in the two storage tanks (102) fall into the two mixing boxes (115) respectively. S2. Next, by using the combination of motor (112), pulley (111), belt, round rod (120) and rotating rod (110), the corresponding stirring rod (121) is driven to rotate, the silver powder is mixed with the cosmetic emulsion, the baking soda is mixed with the cosmetic emulsion, and then the motor (112) is turned off, and the mixture is left to stand for more than ten minutes before observation. S3. When it is necessary to pre-treat the mixture after testing, use a tool to take out the mixture from the mixing box (115), put it into the placement tray (204), then put it into the interior of the two second concave blocks (203), install the sealing plate (202), and then use the control switch (211) and the battery (212) to start the two ultraviolet lamps (205) at the same time for disinfection.
