Description

Technical Field

[0001] The invention relates to a detector, in particular to a quality detector for sunscreen cosmetics, belonging to the technical field of cosmetics detection. Background Art

[0002] Sunscreen cosmetics refer to a type of cosmetics that protect the skin from ultraviolet (UV) damage. They can absorb or reflect ultraviolet rays, reducing the damage of ultraviolet rays to the skin, and usually include sunscreen, sunscreen spray and sunscreen base makeup.

[0003] The Chinese patent, entitled A sunscreen performance tester for sunscreen cosmetics (publication number CN218239822U), discloses a sunscreen performance tester technology that calculates the data of the tested cosmetics based on the product's transmittance to evaluate whether the product meets the specified sunscreen performance requirements at 2 mg per square centimeter. At the same time, a guiding application dosage can be obtained based on the target transmittance, providing users with better usage guidance. However, the overall structure of the tester is relatively complex and relatively large, and cannot meet the daily use of consumers or the testing needs of stores.

[0004] The Chinese patent, entitled "A quality inspection device for sunscreen cosmetics" (patent number ZL202010103251.8), discloses a quality inspection technology for sunscreen cosmetics. By simultaneously inspecting multiple sunscreen products, it is also possible to inspect the performance of the same sunscreen product under different conditions, thereby making the inspection more efficient and filling the gap in the market. During the inspection, it can better simulate the conditions of daily use, making the inspection results more accurate and reliable. However, although the equipment can inspect multiple sunscreen products at the same time and simulate the conditions of daily use to make the inspection results more accurate and reliable, there are still major problems with the overall equipment, and electronic devices such as electric guide rails and ultraviolet detectors are required during the inspection process, resulting in higher overall production and use costs of the inspection equipment.

[0051] In one embodiment, the two pushing mechanisms 3 each include a rubber pad 301, a convex plate 302, a pushing frame 303, a connecting ring 304 and a plurality of first springs 305;

[0055] In one embodiment, the four fill light mechanisms 5 each include an end cap 501 , a lamp tube 502 , an LED lamp bead 503 and a condenser 504 ;

[0059] In one embodiment, a plurality of positioning mechanisms 7 are installed between the outer housing 101 and the turntable 102, and each of the plurality of positioning mechanisms 7 includes an external threaded cylinder 701, a second spring 702, a protrusion 703 and a positioning groove 704;

[0060] The external threaded barrel 701 is threadedly connected to the inner wall of the outer housing 101, the protrusion 703 is slidably connected to the inner wall of the second spring 702, the protrusion 703 is fixedly connected between one end of the protrusion 703 and the inner wall of the external threaded barrel 701, the positioning groove 704 is provided on the inner wall of the turntable 102, and the outer wall of the protrusion 703 is slidably connected to the inner wall of the positioning groove 704;

[0061] By following the movement of the turntable 102, the positioning groove 704 squeezes one side of the protrusion 703, and then the protrusion 703 drives the second spring 702 to be compressed under the action of pressure. When the positioning groove 704 moves to the next protrusion 703, the compressed second spring 702 is used to push the protrusion 703 to slide into the positioning groove 704 again, so as to increase the sense of frustration during the overall rotation of the turntable 102.

[0062] In one embodiment, six reference holes 61 are symmetrically opened on the surface of the turntable 102, and a second light-transmitting sheet 64 is fixedly connected to the bottom of the inner side walls of the six reference holes 61, and a plurality of second fluorescent indicator rings 63 and a second light guide tube 62 are fixedly connected to the upper surface of the second light-transmitting sheet 64, and the plurality of second fluorescent indicator rings 63 and the second light guide tube 62 are arranged at intervals, and a vertical pattern portion 65 is provided on the outer side wall of the turntable 102;

[0063] The second light guide tube 62 guides light to the second fluorescent indicator ring 63 , and the second fluorescent indicator ring 63 absorbs ultraviolet light in normal light, so as to provide a reference for the first fluorescent indicator ring 204 .

[0064] When the present invention is in operation, the sunscreen cosmetics to be tested are placed in the optometry hole 205, and the sunscreen cosmetics in the optometry hole 205 are smoothed by using a scraper to ensure that the sunscreen cosmetics can fully fill the space in the optometry hole 205, and the step-like distribution of the light-transmitting ring 202 and the first light-guiding tube 201 can be used to control the thickness of the sunscreen cosmetics applied, so that sunscreen cosmetics of different thicknesses can be tested simultaneously later.

[0065] When the sunscreen cosmetics are applied and smoothed, the turntable 102 is rotated to drive the placement optometry mechanism 2 to move as a whole, so as to transfer the applied sunscreen cosmetics to the inside of the outer housing 101. While the turntable 102 is rotating, the positioning groove 704 that follows its movement is used to squeeze one side of the protrusion 703, and then the protrusion 703 drives the second spring 702 to be compressed under the action of pressure. When the positioning groove 704 moves to the next protrusion 703, the compressed second spring 702 is used to push the protrusion 703 to slide into the positioning groove 704 again, so as to increase the sense of frustration during the overall rotation of the turntable 102, so as to use the sense of frustration to determine the current position of the placement optometry mechanism 2.

[0066] When the placement optometry mechanism 2 with sunscreen cosmetics applied moves to the bottom of the supplementary light mechanism 5, the two LED lamp beads 503 are used to emit simulated sunlight or ultraviolet rays to illuminate the optometry hole 205 and the reference hole 61, and the first light guide tube 201 is provided to transmit the light passing through the sunscreen cosmetics to the first fluorescent indicator ring 204, so as to transmit the light passing through cosmetics of different thicknesses respectively, and the first fluorescent indicator ring 204 is used to absorb the ultraviolet rays, and the second fluorescent indicator ring 63 is used to absorb the ultraviolet rays in the unblocked light.

[0067] After the sunscreen cosmetics are irradiated, the eye testing mechanism 2 coated with the sunscreen cosmetics is moved to the observation mirror 4 by rotating the turntable 102, so that the brightness of the first fluorescent indicator ring 204 can be observed through the first light-transmitting sheet 203 using the observation mirror 4, and the brightness of the second fluorescent indicator ring 63 can be observed for comparison, so as to judge the sunscreen effect and quality of the cosmetics.

[0068] When the sunscreen cosmetics inspection is completed, the placement optometry mechanism 2 is reset by rotating the turntable 102, and then the convex plate 302 is driven to move by pressing the rubber pad 301. The moving convex plate 302 drives the push frame 303 to push the connecting ring 304 to move. The moving connecting ring 304 drives the first light-transmitting sheet 203 and the first fluorescent indicator ring 204 to slide in the optometry hole 205, and drives the first spring 305 to be compressed, so as to push the first light guide tube 201 and the light-transmitting ring 202 out of the optometry hole 205 as a whole, and clean the cosmetics coated on the surfaces of the first light guide tube 201 and the light-transmitting ring 202. When the cleaning operation is completed, the connecting ring 304 is reset by using the compressed first spring 305, so as to retract the first light guide tube 201 and the light-transmitting ring 202 into the optometry hole 205 for next use.

[0069] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
