Description

Technical Field

[0001] This utility model relates to the field of cosmetic testing technology, and in particular to a quantitative extraction device for cosmetic testing. Background Technology

[0002] Cosmetics are preparations (excluding soap) used on the human body to beautify, preserve, or alter a person's appearance (e.g., for performance purposes), or to cleanse, dye, wipe, correct, or protect the skin, hair, nails, eyes, or teeth. During the production of cosmetics, in order to ensure the quality of cosmetics, it is necessary to inspect them, and samples need to be taken during the inspection.

[0003] A search revealed Chinese Patent Publication No. CN221765008U, which discloses a quantitative sampling device for cosmetic testing. The device includes a sampling tube, a piston, a cover plate, and clamping plates. This invention features a piston inside the sampling tube, a cover plate installed at the bottom of a first flexible tube, and fixed plates on both sides of the cover plate. A knob and a threaded rod are rotatably connected between the two fixed plates. Two clamping plates are symmetrically arranged between the two fixed plates, each with threaded holes on its sidewalls. The threaded rod rotates through these holes. By moving the cover plate to the opening of the cosmetic packaging bottle, the second flexible tube extends into the packaging. Rotating the knob and the threaded rod causes the two clamping plates to move closer together and clamp the bottle opening. During sampling, hand-operated shaking of the sampling tube does not cause the second flexible tube to move inside the cosmetic packaging, thus affecting the sampling effect.

[0004] However, in actual use, the accuracy of extracting cosmetics by observing the scale lines on the sampling tube can be reduced due to visual errors. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a cosmetic testing and quantitative extraction device, which aims to solve the problem that the accuracy of extracting cosmetic volume is reduced due to line-of-sight errors in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cosmetic testing quantitative extraction device, comprising a base, a sample storage container disposed inside the base, a sampling tube fixedly disposed on the upper side of the sample storage container, an extraction tube fixedly disposed at the upper end of the sampling tube, the outer wall of the extraction tube passing through the upper side of the base, a pressure sensor disposed on the inner bottom wall of the extraction tube, a piston slidably connected to the inner wall of the extraction tube, a sliding rod fixedly connected to the upper side of the piston, an extraction mechanism fixedly connected to the top of the sliding rod, a limiting ring plate slidably connected to the outer wall of the sliding rod, the side wall of the limiting ring plate fixedly connected to the inner wall of the extraction tube, a displacement sensor disposed on the inner top wall of the limiting ring plate, and a controller disposed on one side of the base.

[0007] The above technical solution involves fixing the extraction tube with a base, driving the extraction mechanism to move the slide rod upward, which in turn moves the piston upward. The displacement sensor monitors the distance to the piston in real time, and the pressure sensor detects the pressure between the extraction tube and the piston, thereby achieving sampling accuracy.

[0008] As a further description of the above technical solution:

[0009] The extraction mechanism includes an extraction component. The top of the slide rod is fixedly connected to the extraction component. Both ends of the extraction component are fixedly connected to sliders. A bracket is slidably connected to the side of the slider away from the extraction component. The lower sides of the two brackets are fixedly connected to the upper side of the base. A fixing plate is fixedly connected to the side wall between the two brackets. The outer wall of the extraction tube passes through the fixing plate.

[0010] The above technical solution improves the stability of the extraction component by sliding the slider and the bracket, and improves the stability of the extraction tube during the sampling process by fixing the upper part of the extraction tube with the fixing plate.

[0011] As a further description of the above technical solution:

[0012] The extraction assembly includes a sliding plate and a cylinder. The top of the sliding rod is fixedly connected to the lower side of the sliding plate. Both ends of the sliding plate are fixedly connected to the side wall between two sliders. A connecting plate is fixedly connected to one side of the sliding plate. A guide rod is slidably connected inside the sliding plate. The lower end of the guide rod is fixedly connected to the upper side of the fixed plate. The output end of the cylinder is fixedly located on the lower side of the connecting plate.

[0013] The above technical solution involves driving the connecting plate upward through the output end of the cylinder, and then moving the sliding rod upward through the fixed connection between the connecting plate and the sliding rod, thereby helping to realize the sampling function of the device.

[0014] As a further description of the above technical solution:

[0015] A back plate is fixedly connected to the side wall between the two brackets, and the cylinder is mounted on the back plate.

[0016] The above technical solution improves the stability between the two supports by using a backplate, and also provides support for the cylinder, thereby improving the stability of the sampling process.

[0017] As a further description of the above technical solution:

[0018] A sliding groove is provided on one side of the bracket, and the side wall of the slider is slidably connected to the inner wall of the sliding groove.

[0019] The above technical solution allows for the following: when the cylinder drives the sliding plate to move upward, the fixed connection between the sliding plate and the slider drives the slider to move upward. During this process, the contact between the side wall of the slider and the inner side wall of the groove helps to limit the movement of the sliding plate, which is beneficial to improving the stability of the sliding plate movement.

[0020] As a further description of the above technical solution:

[0021] A sample outlet tube is fixedly installed on the lower side of the extraction tube. Both the sample outlet tube and the sampling tube are equipped with a one-way valve. A heating device is installed on the outer wall of the sample outlet tube, and the heating device is located on one side of the base.

[0022] The above technical solution is as follows: the detection of samples requires simulating a certain temperature environment. When it is necessary to detect the extracted sample, the outer wall of the sample tube can be heated by a heating device, thereby realizing the function of preheating the sample.

[0023] As a further description of the above technical solution:

[0024] The sampling tube is equipped with a filter ball.

[0025] The above technical solution addresses the significant impact of impurities in samples on test results during sample detection. By using filter balls to filter the samples, pretreatment is achieved, thereby improving the efficiency of sample detection.

[0026] As a further description of the above technical solution:

[0027] The controller, extraction mechanism, heating device, displacement sensor, and pressure sensor are all electrically connected.

[0028] The above technical solution improves the sampling accuracy of the device through the cooperation of the controller, extraction mechanism, heating device, displacement sensor, and pressure sensor.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the base provides support for the extraction tube, the limiting ring plate provides support for the displacement sensor, and the extraction mechanism drives the slide rod to move upward, causing the piston to move upward. The sample inside the sample storage container is extracted into the extraction tube through the sampling tube. The displacement sensor monitors the piston displacement in real time, the pressure sensor monitors the internal pressure of the extraction tube in real time, and the controller solves the problem of reduced accuracy of cosmetic extraction due to line-of-sight errors in the prior art.

[0031] 2. In this utility model, the longitudinal movement of the slide rod is realized through the cylinder, the connecting plate and the sliding plate. Through the sliding connection between the slider and the bracket, the support of the guide rod by the fixed plate and the sliding connection between the guide rod and the sliding plate, the stable operation of the extraction mechanism is achieved, and the sampling accuracy of the device is also improved.

[0032] 3. In this utility model, the heating device is activated by a controller, and the sample tube is heated by the heating device, thereby achieving the pretreatment of the sample to be tested, which helps to improve the efficiency of sample testing. Attached Figure Description

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Reference Figure 1 , Figure 4 and Figure 5 An embodiment of this utility model provides a cosmetic testing quantitative extraction device, including a base 10, a sample storage container 7 inside the base 10, a sampling tube 8 fixedly installed on the upper side of the sample storage container 7, an extraction tube 12 fixedly installed at the upper end of the sampling tube 8, the outer wall of the extraction tube 12 passing through the upper side of the base 10, a pressure sensor 18 installed on the inner bottom wall of the extraction tube 12, a piston 17 slidably connected to the inner wall of the extraction tube 12, a slide rod 3 fixedly connected to the upper side of the piston 17, an extraction mechanism 2 fixedly connected to the top of the slide rod 3, a limiting ring plate 15 slidably connected to the outer wall of the slide rod 3, the side wall of the limiting ring plate 15 fixedly connected to the inner wall of the extraction tube 12, a displacement sensor 16 installed on the inner top wall of the limiting ring plate 15, and a controller 11 installed on one side of the base 10.

[0042] In this embodiment, Figure 1 The front, back, left and right are the directions. The controller 11 can use a programmable PLC controller, which is existing technology. The limit ring plate 15 has a through hole, and the outer wall of the extraction tube 12 is provided with scale lines.

[0043] Specifically, the base 10 provides support for the extraction mechanism 2, the sample storage container 7, and the extraction tube 12. When using this device, by inputting the sample extraction data to the controller 11, the extraction mechanism 2 is driven to move upward through the fixed connection between the extraction mechanism 2 and the slide rod 3. Through the fixed connection between the slide rod 3 and the piston 17, the piston 17 moves upward inside the extraction tube 12, creating a negative pressure between the piston 17 and the extraction tube 12. The sample inside the sample storage container 7 is then extracted into the extraction tube 12 through the sampling tube 8. The sliding connection between the slide rod 3 and the limiting ring plate 15, and the fixed connection between the limiting ring plate 15 and the extraction tube 12, improve the stability of the upward movement of the slide rod 3.

[0044] During the sample extraction process, the pressure inside the extraction tube 12 changes. The pressure sensor 18 can detect the pressure change and convert it into an electrical signal. The controller 11 processes and analyzes the signal to determine the volume of the extracted sample. The displacement sensor 16 can accurately measure the displacement of the piston 17 and calculate the volume of the extracted sample. By calibrating the scale lines on the outer wall of the extraction tube 12, the problem of reduced accuracy in extracting cosmetic volume due to line-of-sight errors in existing technologies is solved.

[0045] Reference Figure 2 and Figure 3The extraction mechanism 2 includes an extraction component 20. The top of the slide rod 3 is fixedly connected to the extraction component 20. Both ends of the extraction component 20 are fixedly connected to sliders 21. The side of the slider 21 away from the extraction component 20 is slidably connected to a bracket 1. The lower sides of the two brackets 1 are fixedly connected to the upper side of the base 10. A fixing plate 4 is fixedly connected to the side wall between the two brackets 1. The outer wall of the extraction tube 12 passes through the fixing plate 4.

[0046] Specifically, the base 10 provides support for the bracket 1, and the connection between the fixing plate 4 and the bracket 1 improves the stability between the two brackets 1. The fixing plate 4 fixes the upper part of the extraction tube 12, which improves the stability of the extraction tube 12 when extracting samples. The fixed connection between the extraction component 20 and the slide bar 3 causes the extraction component 20 to drive the slide bar 3 to move upward. The sliding connection between the slider 21 and the bracket 1 and the fixed connection between the slider 21 and the extraction component 20 further improve the stability of the slide bar 3 when it moves upward, thereby improving the stability of the extraction mechanism 2 during operation.

[0047] Reference Figure 2 and Figure 4 The extraction assembly 20 includes a sliding plate 201 and a cylinder 203. The top of the slide rod 3 is fixedly connected to the lower side of the sliding plate 201. Both ends of the sliding plate 201 are fixedly connected to the side wall between the two sliders 21. A connecting plate 200 is fixedly connected to one side of the sliding plate 201. A guide rod 202 is slidably connected inside the sliding plate 201. The lower end of the guide rod 202 is fixedly connected to the upper side of the fixed plate 4. The output end of the cylinder 203 is fixedly set on the lower side of the connecting plate 200.

[0048] Specifically, the connecting plate 200 is driven upward by the output end of the cylinder 203. The fixed connection between the connecting plate 200 and the sliding plate 201 causes the sliding plate 201 to move upward. The fixed connection between the sliding plate 201 and the sliding rod 3 causes the sliding rod 3 to move upward, thereby realizing the function of the extraction component 20 moving upward.

[0049] When the sliding plate 201 moves upward, the fixed connection between the sliding plate 201 and the slider 21 drives the slider 21 to move upward. The sliding connection between the slider 21 and the bracket 1 limits the slider 21, thereby improving the stability of the sliding plate 201 during movement. The fixed plate 4 provides support for the guide rod 202. The sliding connection between the guide rod 202 and the sliding plate 201 allows the sliding plate 201 to slide longitudinally along the outer wall of the guide rod 202 during upward movement, further improving the stability of the longitudinal movement of the sliding plate 201, thus helping to improve the sampling accuracy of the device.

[0050] Reference Figure 2A back plate 13 is fixedly connected to the side wall between the two brackets 1, and a cylinder 203 is mounted on the back plate 13.

[0051] Specifically, the stability of the two supports 1 is further improved by the fixed connection between the back plate 13 and the two supports 1, and the stable operation of the cylinder 203 is achieved by the fixed connection between the cylinder 203 and the back plate 13.

[0052] Reference Figure 2 and Figure 3 A groove 14 is provided on one side of the bracket 1, and the side wall of the slider 21 is slidably connected to the inner wall of the groove 14.

[0053] Specifically, as the slider 21 moves upward, the sliding connection between the slider 21 and the groove 14 constrains the side wall of the slider 21 through the inner wall of the groove 14, thereby reducing the swaying of the sliding plate 201 and thus helping to improve the stability of the extraction mechanism 2.

[0054] Reference Figure 1 A sample outlet tube 5 is fixedly installed on the lower side of the extraction tube 12. Both the sample outlet tube 5 and the sampling tube 8 are equipped with a one-way valve. A heating device 6 is installed on the outer wall of the sample outlet tube 5. The heating device 6 is located on one side of the base 10.

[0055] Specifically, the one-way valve inside the sample outlet tube 5 is closed when the device extracts the sample and open when the sample is discharged. The one-way valve inside the sampling tube 8 has the opposite opening and closing state to the one-way valve inside the sample outlet tube 5. This is existing technology. The heating device 6 can use resistance heating, which is existing technology.

[0056] In the testing of cosmetics, it is necessary to simulate the use environment to maintain the sample at a certain temperature. When the sample of the device needs to be tested, the cylinder 203 drives the slide bar 3 to move downward, so that the piston 17 squeezes the sample inside the extraction tube 12 and discharges the sample from the discharge tube 5. After being heated by the heating device 6, the sample enters the container to be tested. Through the cooperation of the displacement sensor 16, the pressure sensor 18 and the controller 11, the amount of sample discharged from the discharge tube 5 is consistent with the demand, thereby realizing the sample pretreatment function of the device.

[0057] Reference Figure 1 The sampling tube 8 is equipped with a filter ball 9;

[0058] Specifically, the filter ball 9 can be made of polytetrafluoroethylene (PTFE), which is an existing technology. When extracting samples from the sample storage container 7, the samples are filtered through the filter ball 9, which helps to improve the efficiency of sample detection.

[0059] Reference Figure 1 , Figure 4 and Figure 5The controller 11, extraction mechanism 2, heating device 6, displacement sensor 16, and pressure sensor 18 are all electrically connected;

[0060] Specifically, the controller 11 controls the extraction mechanism 2 to start, driving the slide bar 3 to move longitudinally to extract or discharge the sample. The pressure sensor 18 monitors the pressure change between the extraction tube 12 and the piston 17 in real time and transmits the signal to the controller 11. The displacement sensor 16 monitors the displacement change of the piston 17 in real time and transmits the signal to the controller 11. Through the processing of the controller 11, the sampling accuracy of the device is improved. When transferring the sample, the controller 11 controls the heating device 6 to start, preheating the sample flowing through the sample outlet tube 5, thereby realizing the accuracy and intelligence of the device.

[0061] Working principle: When using this device, the data for sample extraction is input to the controller 11. The controller 11 controls the cylinder 203 to drive the connecting plate 200 to move upward, which in turn drives the sliding plate 201 to move upward, which in turn drives the sliding rod 3 to move upward, causing the piston 17 to move upward. A negative pressure is generated between the piston 17 and the extraction tube 12. Through the filtration of the filter ball 9, the sample in the sample storage container 7 enters the extraction tube 12 through the sampling tube 8, thus realizing the function of the device in extracting samples.

[0062] The pressure sensor 18 monitors the pressure change between the extraction tube 12 and the piston 17 in real time, and the displacement sensor 16 monitors the displacement change of the piston 17 in real time. The signals are transmitted to the controller 11. After processing by the controller 11 and comparing with the scale on the outer wall of the extraction tube 12, the problem of reduced accuracy of cosmetic extraction capacity due to line-of-sight errors in the existing technology is solved.

[0063] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
