Description

Technical Field

[0001] This utility model relates to the field of essence sampling technology, and in particular to a sampling device for whitening essence containing flavonoid derivatives of magnolia flower. Background Technology

[0002] Magnolia alba refers to an evergreen tree with gray bark and young branches and buds densely covered with pale yellowish-white fine hairs. The leaves are leathery, oblong or lanceolate-elliptic, glabrous on the upper surface and sparsely pubescent on the lower surface. Flavonoids are a class of polyphenolic compounds widely found in plants, possessing diverse biological activities such as antioxidant, anti-inflammatory, and cardiovascular protection. Currently, by sampling Magnolia alba flavonoid derivative whitening essence, samples from different batches or at different depths can be obtained to test the content, distribution uniformity, and purity of its whitening active ingredients (such as flavonoid derivatives), ensuring product quality and the stability of its whitening efficacy.

[0003] An existing cosmetic testing sampler (publication number: CN219798842U) uses a fixed tube at the top of the sampling tube to mount a fixed plate and an electric push rod. The extension and retraction of the electric push rod, in conjunction with the rubber stopper, generates negative pressure suction, which can quickly extract liquid cosmetics for easy sampling and collection. However, it can only directly insert the sampling tube into the cosmetic, and cannot accurately sample different depths of layered liquids, which can easily lead to mixing of sample components, making it difficult to reflect the true state of the cosmetic components. Furthermore, the components are inconvenient to disassemble and clean. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sampling device for whitening essence containing flavonoid derivatives of magnolia.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: To achieve the above objectives, the present invention adopts the following technical solution: A sampling device for whitening essence containing flavonoid derivatives of magnolia flower includes a sampling cylinder body and a protective shell. A cylinder cap is threaded onto the upper end of the sampling cylinder body, and the top of the cylinder cap is connected to the protective shell by screws. An electric push rod is fixedly installed inside the protective shell, and a rubber stopper is fixedly mounted on the output shaft of the electric push rod. A flexible tube is threaded onto the bottom end of the sampling cylinder body, and a sleeve is provided below the flexible tube. A retainer is fitted onto the outer wall of the lower end of the flexible tube, and a positioning ring is fitted onto the outer wall of the sleeve. A second magnetic piece is embedded in the inner wall of the positioning ring, and a first magnetic piece is embedded in the outer wall of the retainer. The first and second magnetic pieces are magnetically connected.

[0006] As a further embodiment of this utility model, the outer wall of the sleeve is fixed with a protruding strip, the positioning ring is fitted and connected to the protruding strip, and the outer walls on both sides of the sampling cylinder body are threaded with connecting pipes.

[0007] As a further embodiment of this utility model, both sets of connecting pipes are equipped with plastic ball valves, and a collection bottle is threaded onto the end of the connecting pipe away from the main body of the sampling cylinder.

[0008] As a further embodiment of this utility model, a sealing ring is installed between the top of the sampling cylinder body and the cylinder cover, and a push post is fixed to the top of the ferrule.

[0009] As a further embodiment of this utility model, a guide strip is fixed to the inner wall of the sleeve, and the ferrule is fitted and connected to the guide strip.

[0010] As a further embodiment of this utility model, a scale is embedded in the outer wall of the sleeve, and the ferrule is slidably connected to the inner wall of the sleeve.

[0011] Compared with the prior art, the present invention has the following beneficial effects: By setting up a positioning ring, a raised strip, a ferrule, a guide strip, a sleeve, and a pusher, the operation involves first pushing the positioning ring to slide along the raised strip on the outer wall of the sleeve, precisely moving it to the target sampling scale position on the scale. Then, under the limiting action of the guide strip, the pusher drives the ferrule to slide stably along the inner wall of the sleeve. When the ferrule slides to the corresponding position of the positioning ring, the second magnetic piece and the first magnetic piece generate an adsorption force, thereby firmly fixing the position of the ferrule and the hose. Throughout the process, the operator can intuitively control the sampling depth through the scale and the positioning ring, which can meet the requirements of component uniformity testing. At the same time, the disassembly and assembly process does not require tools. Simply unscrew the cap, remove the hose, and the positioning ring and ferrule can be separated by directly pulling. This allows all components to be fully covered and cleaned with water or disinfectant, effectively avoiding cross-contamination and ensuring the accuracy of subsequent whitening active ingredient test results.

[0017] Reference Figures 1-5A sampling device for whitening essence of magnolia flavonoid derivatives includes a sampling cylinder body 1 and a protective shell 2. The upper end of the sampling cylinder body 1 is fitted with a cylinder cap 203 by threads. The top of the cylinder cap 203 is connected to the protective shell 2 by screws. An electric push rod 202 is fixedly installed inside the protective shell 2. A rubber stopper 201 is fixedly installed on the output shaft of the electric push rod 202. A hose 4 is fitted with threads at the bottom end of the sampling cylinder body 1. A sleeve 3 is provided below the hose 4. A retainer 401 is fitted onto the outer wall of the lower end of the hose 4. A positioning ring 302 is fitted onto the outer wall of the sleeve 3. A second magnetic piece 404 is embedded in the inner wall of the positioning ring 302. A first magnetic piece 402 is embedded in the outer wall of the retainer 401. The first magnetic piece 402 and the second magnetic piece 404 are magnetically connected.

[0018] According to the sampling requirements, the operator pushes the positioning ring 302 along the protrusion 301 on the outer wall of the sleeve 3. With the help of the scale 304, it is moved to the target sampling depth mark. Then, the operator holds the sleeve 3 and inserts the lower end of the sleeve 3 into the whitening essence of magnolia flavonoid derivatives to be sampled. Then, with the help of the pusher 403, the ferrule 401 is moved along the guide bar 303. When the ferrule 401 slides to the position corresponding to the positioning ring 302, the inner wall of the positioning ring 302... The magnetic sheet 404 and the magnetic sheet 402 on the outer wall of the sleeve 401 generate an adsorption force, thereby fixing the position of the sleeve 401 and the tubing 4. Then, the electric push rod 202 is activated, which drives the rubber stopper 201 to slide upward in the sampling cylinder body 1, generating negative pressure to draw the essence into the sampling cylinder body 1 through the tubing 4. After that, the electric push rod 202 is closed, and the plastic ball valve 7 at the connecting tube 6 is opened to introduce the sample in the sampling cylinder body 1 into the corresponding collection bottle 5.

[0019] In this embodiment, a protrusion 301 is fixed on the outer wall of the sleeve 3, and a positioning ring 302 is fitted and connected to the protrusion 301. Connecting pipes 6 are installed on both outer walls of the sampling cylinder body 1 by threads.

[0020] The magnetic sheet 404 and the magnetic sheet 402 have opposite polarities. When the sleeve 401 slides to the corresponding position of the positioning ring 302, the two will generate an adsorption force, thereby firmly fixing the position of the sleeve 401 and the hose 4.

[0021] In this embodiment, plastic ball valves 7 are installed on both sets of connecting pipes 6, and a collection bottle 5 is threaded onto the end of the connecting pipe 6 away from the sampling cylinder body 1.

[0022] By using the scale 304 in conjunction with the positioning ring 302, the operator can intuitively control the sliding position of the positioning ring 302 on the sleeve 3, thereby accurately determining the sampling depth.

[0023] In this embodiment, a sealing ring 101 is installed between the top of the sampling cylinder body 1 and the cylinder cover 203, and a pusher 403 is fixed to the top of the ferrule 401.

[0024] The guide bar 303 limits the sliding direction of the ferrule 401 to prevent the ferrule 401 from rotating and misaligning when sliding along the inner wall of the sleeve 3.

[0025] In this embodiment, a guide strip 303 is fixed to the inner wall of the sleeve 3, and the ferrule 401 is fitted and connected to the guide strip 303.

[0026] The protrusion 301 provides a sliding track for the positioning ring 302 and restricts the rotation of the positioning ring 302 around the sleeve 3, ensuring that the positioning ring 302 can slide accurately along the scale without deviating, thereby helping to determine the sampling depth.

[0027] In this embodiment, a scale 304 is embedded in the outer wall of the sleeve 3, and the ferrule 401 is slidably connected to the inner wall of the sleeve 3.

[0028] The operator can use the pusher 403 to drive the sleeve 401 to slide stably along the sleeve 3, providing operational support for the subsequent precise alignment of the sleeve 401 and the positioning ring 302 and the realization of magnetic adsorption fixation.

[0029] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: First, using the thread, the cylinder cap 203 is twisted to connect with the top of the sampling cylinder body 1, ensuring that the sealing ring 101 at the top of the sampling cylinder body 1 is compressed and fitted to achieve negative pressure sealing. Then, the positioning ring 302 is fitted onto the protrusion 301 on the outer wall of the sleeve 3, and then the ferrule 401 on the hose 4 is pushed to fit with the guide strip 303. According to the sampling requirements, the positioning ring 302 is pushed along the protrusion 301 on the sleeve. The outer wall of tube 3 slides, and with the help of the scale 304, it is moved to the target sampling depth mark. Then, the operator holds tube 3 and inserts the lower end of tube 3 into the whitening essence of magnolia flavonoid derivatives to be sampled. Then, with the help of the pusher 403, the card sleeve 401 slides along the guide strip 303. When the card sleeve 401 slides to the position corresponding to the positioning ring 302, the magnetic sheet 404 on the inner wall of the positioning ring 302 and the magnetic sheet 402 on the outer wall of the card sleeve 401 generate an adsorption force, thereby fixing the card. Position the sleeve 401 and the hose 4, then activate the electric push rod 202. The electric push rod 202 drives the rubber stopper 201 to slide upward inside the sampling cylinder body 1, generating negative pressure to draw the essence into the sampling cylinder body 1 through the hose 4. After that, close the electric push rod 202, and then open the plastic ball valve 7 at the connecting tube 6 to introduce the sample in the sampling cylinder body 1 into the corresponding collection bottle 5. If it is necessary to collect essence samples at different depths, simply push the positioning ring 302 along the convex strip 301 to adjust it to the new position. Repeat the above steps of pushing the ferrule 401 and then starting the electric push rod 202. After all samples are collected, first close the plastic ball valve 7, then unscrew the cylinder cap 203 and the sampling cylinder body 1, remove the hose 4 and the connecting tube 6, lift the positioning ring 302 to separate it from the protrusion 301, take out the ferrule 401 and the hose 4, and rinse the sampling cylinder body 1, hose 4, ferrule 401, sleeve 3 and other parts with clean water. If necessary, soak them in disinfectant solution for disinfection, dry them and store them properly for the next use.
