Description

Technical Field

[0001] This utility model relates to the field of cosmetic testing and sampling technology, specifically to a sampling device for cosmetic testing. Background Technology

[0002] Cosmetics come into direct contact with the skin. If they contain excessive levels of heavy metals (such as lead and mercury), harmful microorganisms (such as Staphylococcus aureus), or prohibited ingredients, they may cause allergies, infections, or even chronic poisoning. Testing can help intercept substandard products in advance and avoid health risks.

[0003] Cosmetics exist in various states. When testing and using cosmetics, it is necessary to sample various cosmetics. Traditionally, a single spoon is used to sample solid cosmetics, while a suction device is required to sample liquid cosmetics.

[0004] This results in the sampler being insufficiently adaptable to different forms of cosmetics during sampling, failing to meet diverse testing needs. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a sampling device for cosmetic testing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for cosmetic testing, comprising a sampling tube, a piston slidably connected inside the sampling tube, a piston rod fixedly connected to the upper side of the piston, and a push plate fixedly connected to the top end of the piston rod extending out of the sampling tube; further comprising:

[0007] A pipette is fixed to the lower side of a sample tube. A power box is fixed to the lower side of the sample tube. A connecting sleeve is rotatably connected to the inner wall of the lower side of the power box. A connecting tube is fixed inside the connecting sleeve. The connecting tube is fixed to the inner wall of the upper side of the hollow drill bit. The pipette is inserted into the connecting tube.

[0008] A drive mechanism is used to drive the connecting sleeve to rotate;

[0009] A connecting tube, wherein the right side of the sample tube is fixedly connected to the connecting tube, and a connecting seat is slidably connected inside the connecting tube;

[0010] A lifting mechanism is provided to drive the connecting seat to move along the connecting cylinder.

[0011] Preferably, the drive mechanism includes gear a and gear b, gear a is fixedly connected to the connecting sleeve, and gear b is rotatably connected to the lower inner wall of the power box, and gear a and gear b mesh.

[0012] Preferably, the lifting mechanism includes a drive motor and a screw. The drive motor is fixedly connected to the lower inner wall of the connecting cylinder, the screw is rotatably connected inside the connecting cylinder, the output shaft of the drive motor is fixedly connected to the screw, the connecting seat meshes with the screw, and the bottom end of the screw extends into the power box and is fixedly connected to a gear b.

[0013] Preferably, a limiting groove is provided on the right side of the connecting cylinder, and the connecting seat is slidably connected in the limiting groove.

[0014] Preferably, a mounting base is slidably connected to the sampling tube and the connecting cylinder, a scraper is engaged within the mounting base, and the sampling tube and the connecting cylinder are slidably connected within the scraper.

[0015] Preferably, a battery storage box is fixedly connected to the front side of the sampling tube.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention uses a drive motor to rotate a screw, which in turn rotates gears b and a. Gear a then rotates a connecting sleeve and a hollow drill bit. The hollow drill bit partially pulverizes solid cosmetics, making it easier for a straw to extract them. Pulling a push plate moves a piston rod and piston upwards, allowing other forms of cosmetics to be extracted through the straw. This invention solves the problem of existing devices being insufficiently adaptable to different forms of cosmetics and unable to meet diverse testing needs.

[0018] This invention uses a drive motor to drive a screw to rotate. The rotation of the screw causes the connecting seat, mounting seat, and scraper to move downwards. The downward movement of the mounting seat and scraper removes cosmetics adhering to the sampling tube, thus preventing contamination of the sampled cosmetics and affecting the accuracy of the test.

A connecting sleeve 7 is rotatably connected to the inner wall of the lower side of the power box 6. A connecting tube 9 is fixed inside the connecting sleeve 7. The connecting tube 9 is fixed to the inner wall of the upper side of the hollow drill bit 10. The pipette 5 is inserted into the connecting tube 9.

[0034] The drive mechanism is used to drive the connecting sleeve 7 to rotate;

[0035] Connecting tube 12, the right side of the sample tube 1 is fixedly connected to the connecting tube 12, and a connecting seat 133 is slidably connected inside the connecting tube 12;

[0036] The lifting mechanism is used to drive the connecting seat 133 to move along the connecting cylinder 12.

[0037] In this embodiment, as Figures 1-2 ,as well as Figures 3-4As shown, the lifting mechanism drives the screw 132 to rotate, the rotation of the screw 132 drives the gears b82 and a81 to rotate, the rotation of gear a81 drives the connecting sleeve 7 and the hollow drill bit 10 to rotate, and the hollow drill bit 10 partially crushes the solid cosmetics so that the straw 5 can draw out the solid cosmetics.

[0038] Pulling the push plate 3 causes the piston rod 2 and piston 4 to move upward, and other forms of cosmetics are extracted through the straw 5;

[0039] The lifting mechanism drives the screw 132 to rotate. The rotation of the screw 132 causes the connecting seat 133, the mounting seat 11 and the scraper 14 to move downward. The downward movement of the mounting seat 11 and the scraper 14 scrapes off the cosmetics adhering to the sampling tube 1, so as to avoid contaminating the sampled cosmetics and affecting the detection accuracy.

[0040] Example 2

[0041] The difference from Embodiment 1 is that this embodiment discloses a drive structure for the hollow drill bit 10:

[0042] The drive mechanism includes gear a81 and gear b82. Gear a81 is fixedly connected to the connecting sleeve 7, and gear b82 is rotatably connected to the lower inner wall of the power box 6. Gear a81 and gear b82 mesh.

[0043] In this embodiment, as Figure 2 and Figure 3 As shown, the lifting mechanism drives the screw 132 to rotate, the rotation of the screw 132 drives the gears b82 and a81 to rotate, the rotation of gear a81 drives the connecting sleeve 7 and the hollow drill bit 10 to rotate, and the hollow drill bit 10 partially crushes the solid cosmetics so that the straw 5 can draw out the solid cosmetics.

[0044] Example 3

[0045] The difference from Embodiment 2 is that this embodiment discloses a lifting structure for the mounting base 11 and the scraper 14:

[0046] The lifting mechanism includes a drive motor 131 and a screw 132. The drive motor 131 is fixed to the lower inner wall of the connecting cylinder 12, and the screw 132 is rotatably connected inside the connecting cylinder 12. The screw 132 is fixed to the output shaft of the drive motor 131. The connecting seat 133 meshes with the screw 132.

[0049] A battery storage box 15 is fixed to the front side of the sampling tube 1.

[0050] In this embodiment, as Figure 2 and Figure 3 As shown, the drive motor 131 drives the screw 132 to rotate. The rotation of the screw 132 drives the connecting seat 133, the mounting seat 11 and the scraper 14 to move downward. The mounting seat 11 and the scraper 14 move downward to scrape off the cosmetics adhering to the sampling tube 1, so as to avoid the cosmetics remaining on the sampling tube 1 from contaminating it when other cosmetics are drawn.

[0051] The screw 132 rotates, causing the connecting seat 133 to slide inside the connecting cylinder 12. The connecting seat 133 moves along the limiting groove 16, and the limiting groove 16 limits the connecting seat 133.

[0053] In use, this utility model is as follows:

[0054] The drive motor 131 drives the screw 132 to rotate. The rotation of the screw 132 drives the gears b82 and a81 to rotate. The rotation of gear a81 drives the connecting sleeve 7 and the hollow drill bit 10 to rotate. The hollow drill bit 10 partially crushes the solid cosmetics so that the straw 5 can draw out the solid cosmetics.

[0055] Pulling the push plate 3 causes the piston rod 2 and piston 4 to move upward, and other forms of cosmetics are extracted through the straw 5;

[0056] The drive motor 131 drives the screw 132 to rotate. The rotation of the screw 132 causes the connecting seat 133, the mounting seat 11 and the scraper 14 to move downward.
