Description

Technical Field

[0001] The utility model relates to the technical field of cosmetic inspection, and more specifically, to a sampler for cosmetic inspection. 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, lips and teeth, by smearing, spraying or other similar methods, for the purpose of cleaning, maintenance, beautification, modification and change of appearance, or correction of human odor and maintenance of good condition. Because cosmetics are usually in direct contact with the human body, their safety issues have attracted much attention. Cosmetics sold in the Chinese market must comply with relevant product standards. Therefore, sampling and testing of cosmetics are required during the production of cosmetics. The testing of cosmetics is actually the testing of total active ingredients, heavy metals such as lead, arsenic, mercury, methanol, phosphate, pH, moisture content, etc.

[0003] In the existing liquid sampling device, during the subsequent use, the suction sampling head used to absorb the liquid is generally composed of a single pipe. In the later use process, when the staff completes the absorption of the cosmetic fluid, the fluid adsorbed on the inner wall of the pipe used to absorb the fluid is easy to cause ground contamination during the movement. In addition, when sampling, usually only a single depth can be sampled, which can easily lead to errors between the detected results and the actual results, affecting the detection results. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a sampler for cosmetic inspection to solve the problem that after the cosmetic fluid is sucked, the fluid adsorbed on the inner wall of the pipe used to suck the fluid is easy to cause ground contamination during the movement, and when sampling, usually only a single depth can be sampled, which easily leads to errors between the detected results and the actual results, affecting the detection results.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a sampler for cosmetic inspection, comprising a lifting assembly, a rotating sampling device is slidably installed on one side of the lifting assembly, and a sampling head is detachably installed on the bottom of the rotating sampling device; the rotating sampling device comprises a support rod, a sleeve frame is fixedly connected to one side of the support rod, a sampling barrel is rotatably installed inside the sleeve frame, a protective cover is fixedly connected to the top of the sampling barrel, a sliding block is fixedly connected to the side of the support rod away from the sleeve frame, and indicator needles are fixedly connected to both sides of the support rod close to one end of the sliding block. A transmission gear is fixedly sleeved on the outer surface of the lower end of the sample barrel, and the support rod is fixedly connected to a rotating motor near the top of the sampling barrel. The bottom of the rotating motor is fixedly connected to a driving gear, and the driving gear is rotatably installed inside the support rod. The outer surface of the transmission gear is meshed with the outer surface of the driving gear. The interior of the protective cover is located at the top of the sampling barrel and is fixedly connected to a battery. An electric telescopic rod is provided at the bottom of the battery. A rubber piston block is fixedly connected to the bottom of the electric telescopic rod. The rubber piston block is slidably installed inside the sampling barrel, and a mounting head is fixedly connected to the bottom of the sampling barrel.

[0006] Among them, the lifting assembly includes a base plate, one end of the top of the base plate is fixedly connected to a lifting frame, a lifting slot is opened on the side of the lifting frame, the top of the lifting frame is fixedly connected to a lifting motor, the bottom of the lifting motor is fixedly connected to a threaded rod, the threaded rod is rotatably installed inside the lifting slot, and scales are fixedly connected to both sides of the lifting frame.

[0007] The lifting slot is threadedly connected to the inside of the sliding block, and the support rod is slidably installed on the side of the lifting slot on the side close to the sliding block, and the indicating needle slides on the side of the scale.

[0008] Wherein, the sampling head includes a sample bottle, the top of the sample bottle is fixedly connected to a threaded head, the bottom of the sample bottle is fixedly connected to a connecting head, the bottom end of the inside of the sample bottle is fixedly connected to a one-way valve, the bottom of the one-way valve is fixedly connected to a connecting head, the outer surface of the connecting head is threadedly connected to a sleeve nozzle, and the bottom of the sleeve nozzle is fixedly connected to a suction needle.

[0009] Wherein, the bottom of the suction needle is curved.

[0010] Technical effects and advantages of the utility model:

[0011] In the above scheme, according to the depth of the sampled cosmetics, the lifting motor is started to rotate the threaded rod, and the sliding block is controlled to descend inside the lifting slot, so that the suction needle reaches the height inside the cosmetics, so that negative pressure is formed inside the sampling tube and the sample bottle at the bottom of the sampling tube, and the suction needle absorbs the cosmetic sample. According to the position of the indicator needle sliding on the side of the scale, the depth of the sampling head descending is determined, and the cosmetic samples are sampled at different depths, thereby improving the accuracy of cosmetic sampling;

[0012] When the suction needle sucks the cosmetic sample, the rotating motor starts the driving gear to rotate, thereby controlling the rotation of the sampling tube inside the sleeve frame, and then driving the sampling head to rotate and absorb during the sampling process, sampling the cosmetics in multiple directions, making the sampling more uniform, reducing the error with the actual existence, and improving the sampling accuracy;

[0013] When the cosmetics are sucked into the sample bottle through the suction needle, the cosmetics sample can be extracted by rotating the sleeve nozzle and the sample bottle, and the cover is tightened with the threaded head to complete the preservation of the cosmetics sample. The overall closed sampling can avoid external contamination and affect the sampling accuracy;

[0014] By setting the bottom of the suction needle to be curved, the cosmetic sample is prevented from adhering to the inner wall of the suction needle, causing the sampling head to fall from the suction needle during movement, thereby contaminating the work place.

The interior of the protective cover 24 is located at the top of the sampling barrel 23 and is fixedly connected to a battery 27. The bottom of the battery 27 is provided with an electric telescopic rod 28. The bottom of the electric telescopic rod 28 is fixedly connected to a rubber piston block 29. The rubber piston block 29 is slidably installed in the interior of the sampling barrel 23. The bottom of the sampling barrel 23 is fixedly connected to a mounting head 210. The sliding of the indicator needle 26 on the side of the scale 15 is used to determine the depth of the sampling head 3 to be lowered according to the sliding position of the indicator needle 26 on the side of the scale 15, and the different depths of the cosmetic sample are sampled. In addition, when the electric telescopic rod 28 controls the rubber piston block 29 to extend and retract, the rotating motor 211 starts the driving gear 212 to rotate, thereby controlling the rotation of the sampling barrel 23 inside the sleeve frame 22, thereby driving the sampling head 3 in the sampling process, thereby sampling in multiple directions and improving the accuracy of the sample.

[0023] As attached Figure 4 As shown, the lifting assembly 1 includes a base plate 11, one end of the top of the base plate 11 is fixedly connected to a lifting frame 12, a lifting slot 13 is opened on the side of the lifting frame 12, a lifting motor 14 is fixedly connected to the top of the lifting frame 12, a threaded rod is fixedly connected to the bottom of the lifting motor 14, and the threaded rod is rotatably installed inside the lifting slot 13, and scales 15 are fixedly connected to both sides of the lifting frame 12.
