Description

Technical Field

[0001] The utility model relates to the technical field of cosmetic detection and sampling, in particular to a rapid sampling device for cosmetic detection. Background Art

[0002] Cosmetics refer to chemical industrial products or fine chemical products that are spread on any part of the human body surface, such as skin, hair, nails or lips and teeth, by smearing, spraying or other similar methods, for the purpose of cleaning, maintenance, beautification, modification, changing appearance, correcting body odor or maintaining good condition. Since cosmetics usually come into contact with the skin, their safety needs to be ensured, so it is necessary to test and sample their ingredients before they are officially put into use, that is, to test the total active ingredients, lead, arsenic, heavy metal components such as mercury and so on in the cosmetics.

[0003] In the existing cosmetics detection sampling device, the cosmetics to be tested are generally stored in a sample storage bottle, and a sampler with a principle similar to that of a syringe is inserted into the sample storage bottle to complete the sampling. However, under such a sampling method, the sampler will inevitably come into direct contact with the cosmetics, so that the outer wall of the sampler will be sticky with cosmetic residues. Direct sampling again will not only affect the accuracy of the next sampling, but also cause unnecessary pollution to the cosmetics in the sample storage bottle. Therefore, after completing a sampling, the outer wall of the sampler needs to be cleaned, and a certain amount of drying time needs to be reserved after cleaning to allow the outer wall of the sampler to dry until no cleaning water remains. The existence of the cleaning process and the drying process will undoubtedly increase the interval time between two adjacent samplings, resulting in an unnecessary increase in the time of continuous sampling, making it difficult to meet the requirements of rapid sampling.

[0004] Therefore, it is necessary to invent a rapid sampling device for cosmetics testing to solve the above problems. Utility Model Content

[0005] In order to address the deficiencies of the prior art, the purpose of the utility model is to provide a rapid sampling device for cosmetic testing, which solves the problem in the prior art that the existence of the cleaning process and the drying process undoubtedly increases the interval time between two adjacent samplings, resulting in unnecessary increase in the time of continuous sampling, making it difficult to meet the requirements of rapid sampling.

[0006] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0007] A quick sampling device for cosmetics testing, comprising a cover plate that can abut against the top of a sample storage bottle containing cosmetics, a cover tube connected to the outer side of the bottom surface of the cover plate and can contact the outer peripheral side wall of the sample storage bottle, and a sleeve that is detachably clamped to the center of the cover plate and has open ends at the top and bottom, the bottom end of the sleeve is connected to an internally hollow bottom plate, a bottom suction ring is embedded in the bottom plate, an internally hollow annular scraper is connected to the bottom end of the bottom plate, and a plurality of leakage holes are opened in the bottom plate, the top end of the sleeve is detachably abutted against an internally hollow top plate, a top suction ring is embedded in the top plate, a sampler is detachably and longitudinally slidably penetrated in the sleeve, an internally hollow truncated cone scraper is clamped in the middle of the inner peripheral side wall of the sleeve, and a water storage tank is opened on the top surface of the truncated cone scraper;

[0008] When the sampler extends into the sleeve from top to bottom and enters the sample storage bottle to take samples, the outer side wall of the sampler sequentially longitudinally slides in contact with the top suction ring, the conical scraper, the bottom suction ring and the inner side wall of the annular scraper; when the sampler emerges from the sample storage bottle from bottom to top and completes sampling, the outer side wall of the sampler sequentially longitudinally slides in contact with the annular scraper, the bottom suction ring, the conical scraper and the inner side wall of the top suction ring.

[0009] As a preferred solution of the utility model, a circular groove is provided at the center of the cover plate, a clamping sleeve is detachably embedded in the circular groove, and the sleeve is clamped in the clamping sleeve.

[0010] As a preferred solution of the utility model, a needle which can be inserted into a sample storage bottle for sampling is detachably connected to the bottom end of the sampler.

[0011] As a preferred solution of the utility model, a butt ring is connected to the bottom end of the cover plate, and the inner and outer diameters of the butt ring are adapted to the inner and outer diameters of the sample storage bottle.

[0012] As a preferred solution of the utility model, guide posts are connected to symmetrical positions on the top of the cover plate, and a lifting frame is commonly connected between the tops of the two guide posts.

[0013] As a preferred solution of the utility model, the symmetrical positions on the top side of the outer peripheral side wall of the sampler are extended to form an extension seat, the bottom side of the extension seat is connected to a top magnetic block, the top of the cover plate is adapted to each guide column position and a longitudinally retractable telescopic frame is installed, the top of the telescopic frame is connected to a cross plate, the top side of the cross plate is connected to a bottom magnetic block, and the cross plate can slide longitudinally along the guide column;

[0014] When the top magnetic block is in magnetic contact with the bottom magnetic block, the position of the sampler and the horizontal plate is locked.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] In the utility model, when the sampler slides from top to bottom to extend into the sleeve and enter the sample storage bottle for sampling, the outer peripheral side wall of the sampler is longitudinally slidably contacted with the top suction ring and the inner peripheral side wall of the conical scraper in turn, so that the cleaning water that may exist on the outer wall of the sampler for the initial sampling is adsorbed by the top suction ring and scraped off by the conical scraper, and the residual cleaning water on the outer wall is removed, thereby preventing the cleaning water from entering the sample storage bottle, that is, the cleaning water removal process of the outer wall of the sampler that is initially inserted into the sample storage bottle is completed; and when the sampler is exposed from the sample storage bottle from bottom to top and the sampling is completed, the outer wall of the sampler is longitudinally slidably contacted with the annular scraper, the bottom suction ring and the inner peripheral side wall of the conical scraper in turn, so that the cosmetics stuck on and remaining on the outer wall of the sampler are scraped downwards by the annular scraper, adsorbed by the bottom suction ring and scraped downwards by the conical scraper in turn, and the existence of the leakage hole can make part of the scraped cosmetics directly fall into the sample storage bottle, thereby effectively removing the cosmetics stuck on and remaining on the outer wall of the sampler. The outer wall of the sampler is kept clean, and finally it is further adsorbed by contact with the top suction ring, so as to ensure that the outer wall of the sampler remains dry and clean when it leaks out of the casing. Therefore, the external cleaning process of the sampler after a single sampling is avoided, so that the sampler after a single sampling can be directly inserted into the casing again and enter the sample storage bottle to complete the next sampling. In the process of this insertion, the outer wall of the sampler is again subjected to the outer wall cleaning operation during the initial insertion for sampling, further ensuring that the outside of the sampler entering the sample storage bottle is dry and clean. Not only the cleaning and drying process of the outer wall of the sampler between two adjacent samplings is avoided, but also the outside of the sampler is continuously scraped and cleaned during the insertion and leakage sampling process, effectively ensuring that the uncleaned outer wall of the sampler can also be kept clean, shortening the cleaning time and drying time spent between two adjacent samplings, so that the sampler can perform continuous sampling to meet the requirements of rapid sampling and detection.

[0024] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0025] The utility model provides Figure 1-Figure 5 A quick sampling device for cosmetics testing shown in the figure comprises a cover plate 1 which can abut against the top of a sample storage bottle filled with cosmetics, a cover tube 2 which is connected to the outer side of the bottom surface of the cover plate 1 and can contact the outer peripheral side wall of the sample storage bottle, and a sleeve 5 which is detachably clamped to the center of the cover plate 1 and has open ends at the top and bottom. The bottom end of the sleeve 5 is connected to an internally hollow bottom plate 6, a bottom suction ring 8 is embedded in the bottom plate 6, an internally hollow annular scraper 9 is connected to the bottom end of the bottom plate 6, and a plurality of leakage holes 7 are provided in the bottom plate 6. The top of the sleeve 5 is detachably abutted against an internally hollow top plate 10, a top suction ring 11 is embedded in the top plate 10, a sampler 12 is detachably and longitudinally slidably penetrated in the sleeve 5, an internally hollow truncated cone scraper 14 is clamped in the middle of the inner peripheral side wall of the sleeve 5, a water storage tank 15 is provided on the top surface of the truncated cone scraper 14, and the water storage tank 15 can temporarily store the cleaning water residue or cosmetic residue scraped off the outer wall of the sampler 12;

[0026] When the sampler 12 extends from top to bottom into the sleeve 5 and enters the sample storage bottle for sampling, the outer side wall of the sampler 12 sequentially longitudinally slides in contact with the top suction ring 11, the conical scraper 14, the bottom suction ring 8 and the inner side wall of the annular scraper 9; when the sampler 12 emerges from the sample storage bottle from bottom to top and completes sampling, the outer side wall of the sampler 12 sequentially longitudinally slides in contact with the inner side wall of the annular scraper 9, the bottom suction ring 8, the conical scraper 14 and the top suction ring 11.

[0027] A circular groove is provided in the center of the cover plate 1, in which a clamping sleeve 4 is detachably embedded. The sleeve 5 is clamped in the clamping sleeve 4. The clamping sleeve 4 can fix the position of the sleeve 5 in the center of the cover plate 1 and facilitate the removal of the sleeve 5.

[0028] The bottom of the sampler 12 is detachably connected with a needle 13 which can be inserted into the sample storage bottle for sampling. The sampler 12 is similar to a syringe. The needle 13 is inserted into the sample storage bottle, and the sampler 12 is used to absorb and sample the cosmetics.

[0029] A butt ring 3 is connected to the bottom end of the cover plate 1, and the inner and outer diameters of the butt ring 3 are adapted to the inner and outer diameters of the sample storage bottle. The butt ring 3 is made of flexible material to prevent the cover plate 1 from directly contacting the bottom end of the sample storage bottle and causing the bottle mouth to break.

[0030] Guide columns 17 are connected to symmetrical positions on the top of the cover 1, and a lifting rack 18 is commonly connected between the tops of the two guide columns 17. The lifting rack 18 can be used to change the position of the entire cover 1 structure, thereby completing the fixation of the cover 1 and the sample storage bottle. The presence of the cover tube 2 can ensure that the sample storage bottle is in a closed state during the sampling process.

[0031] The symmetrical positions on the top side of the outer peripheral side wall of the sampler 12 are extended to form an extension seat 16, and the bottom side of the extension seat 16 is connected to a top magnetic block 20. The top of the cover plate 1 is adapted to each guide column 17. A telescopic frame 22 that can be telescoped longitudinally is installed. The top of the telescopic frame 22 is connected to a transverse plate 19, and the top side of the transverse plate 19 is connected to a bottom magnetic block 21. The transverse plate 19 can slide longitudinally along the guide column 17, and the telescopic frame 22 slides longitudinally downward, so that the sampler 12 extends into the sleeve 5 and enters the sample storage bottle to complete the cosmetic sampling. The telescopic frame 22 moves longitudinally upward, so that the sampler 12 after sampling leaks out of the sleeve 5 and completes a single sampling operation;

[0032] When the top magnetic block 20 and the bottom magnetic block 21 are in magnetic contact, the position of the sampler 12 and the horizontal plate 19 is locked.

[0033] In the present invention, when the sampler 12 slides from top to bottom to extend into the sleeve 5 and enter the sample storage bottle for sampling, the outer peripheral side wall of the sampler 12 sequentially longitudinally slides with the top suction ring 11 and the inner peripheral side wall of the round table scraper 14, so that the cleaning water that may exist on the outer wall of the sampler 12 for the first sampling is adsorbed by the top suction ring 11 and scraped off by the round table scraper 14, and the residual cleaning water on the outer wall is removed, so that the cleaning water is prevented from entering the sample storage bottle, that is, the cleaning water on the outer wall of the sampler 12 for the first sampling is removed. When the sampler 12 is exposed from the bottom to the top of the sample storage bottle and the sampling is completed, the outer wall of the sampler 12 is longitudinally slidably contacted with the annular scraper 9, the bottom suction ring 8 and the inner side wall of the round table scraper 14 in sequence, so that the cosmetics sticking to and remaining on the outer wall of the sampler 12 are scraped downward by the annular scraper 9, adsorbed by the bottom suction ring 8 and scraped downward by the round table scraper 14 in sequence, and the existence of the leakage hole 7 allows part of the scraped cosmetics to fall directly into the sample storage bottle, thereby effectively removing the cosmetics sticking to and remaining on the outer wall of the sampler 12. The cosmetics are kept clean by the outer wall of the sampler 12, and finally, they are further adsorbed by contact with the top suction ring 11, so as to ensure that the outer wall of the sampler 12 is kept dry and clean when it leaks out of the sleeve 5. Therefore, the external cleaning process of the sampler 12 after a single sampling is avoided, so that the sampler 12 after a single sampling can be directly inserted into the sleeve 5 again and enter the sample storage bottle to complete the next sampling. In the process of this insertion, the outer wall of the sampler 12 is again subjected to the outer wall cleaning operation during the initial insertion for sampling, so as to further ensure that the outside of the sampler 12 entering the sample storage bottle is dry and clean, which not only avoids the cleaning and drying process of the outer wall of the sampler 12 between two adjacent samplings, but also continuously scrapes and cleans the outside of the sampler 12 during the process of inserting the sampling and leaking out to complete the sampling, effectively ensuring that the outer wall of the sampler 12 that has not been cleaned can also be kept clean, shortening the cleaning time and drying time spent between two adjacent samplings, so that the sampler 12 can perform continuous sampling to meet the requirements of rapid sampling and detection.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
