Description

Technical Field

[0001] The present invention relates to the technical field of cosmetics detection, and in particular to a cosmetics detection device with a microorganism anti-enrichment function. Background Art

[0002] Since the raw materials and additives of cosmetics contain a large amount of oil, colloid, protein, polyols and other nutrients and a large amount of water, these are the nutrients such as carbon source, nitrogen source and water necessary for the growth and reproduction of microorganisms. Under suitable temperature, humidity and other conditions, microorganisms will grow and reproduce in large numbers.

[0003] Most of the existing detection devices manually sample cosmetics, then place the sampled cosmetics in a culture dish and use the detection equipment for detection. Since the existing liquid cosmetics have a certain depth when stored, the cosmetics may be stratified during storage, and manual sampling usually only samples the cosmetics at a single depth, which can easily lead to inaccurate subsequent detection results. If a single sampling tube is used for multiple samplings, part of the liquid of the previously sampled cosmetics will adhere to the inner wall of the sampling tube, causing mutual mixing during subsequent sampling, which will affect the detection results. After the sampling is completed, due to the liquid adhering to the inner wall of the sampling tube, after a period of time, it is easy to cause microbial enrichment on the inner wall of the sampling tube, resulting in the sampling tube being unable to be used again. At the same time, microorganisms will enter the sample of the cosmetics test, resulting in inaccurate test results. Therefore, it is necessary to design a cosmetics detection device with a microbial anti-enrichment function to solve the above problems. Summary of the invention

The device can automatically sample cosmetics at two depths twice during detection, so as to more accurately judge whether the ingredients in the cosmetics are qualified. By setting a serpentine tube and a sterilization lamp, it can avoid the situation where the enriched microorganisms generated in the pipeline affect the detection results. At the same time, the air pump can be used to completely press out the residual liquid in the pipeline to avoid multiple samples from mixing with each other during multiple samplings, and the pipeline can be kept in a relatively dry state when the detection device is on standby.

The bottom space of the sampling box 14 is connected with a hose 11. Both the hose 11 and the sampling tube 23 are provided with a one-way valve. Two contact blocks 6 are provided on the right side of the vertical plate 5. The two contact blocks 6 and the moving block 10 constitute two control switches. An external power supply and a controller are provided on the box body 1. The external power supply, the two control switches and the first electromagnet 17 constitute a loop through a wire. The two control switches are connected in parallel in the loop. Cosmetics can only enter the sampling box 14 in one direction through the sampling tube 23. The gas or liquid in the bottom space of the sampling box 14 enters the serpentine tube 25 in one direction through the hose 11.

[0031] As an embodiment of the present invention, a sterilization component is provided in the box body 1, and the sterilization component includes a sterilization chamber arranged in the box body 1. A plurality of sterilization lamps 24 are provided on the inner top of the sterilization chamber. The sterilization lamps 24 need to be in working state at all times to avoid the enrichment and growth of microorganisms in the serpentine tube 25.

When the sampled liquid is completely discharged into the sampling dish 32, the weight of the sampling dish 32 is large at this time, and the pressure sensor generates an electrical signal and transmits it to the controller, and the controller controls the second electromagnet 35 to be energized to generate a repulsive force on the push plate 37.

[0033] As an embodiment of the present invention, a control box 29 is fixedly connected to the lower end of the disk 28, a vertical rod 30 passes through the control box 29, a slider 39 is slidably connected inside the control box 29, a rack 40 is fixedly connected to the right side of the slider 39, a rotating gear 19 is provided on the vertical rod 30, and a one-way bearing is provided between the vertical rod 30 and the rotating gear 19, so that the slider 39 drives the rack 40 to move left, and at this time the rotating gear 19 drives the vertical rod 30 to rotate, and when the slider 39 drives the rack 40 to move right, at this time the rotating gear 19 will not drive the vertical rod 30 to rotate.

[0034] As an embodiment of the present invention, the inner top of the sampling box 14 and the upper end of the piston 22 are fixedly connected with an L-shaped rod 20, and an air pump 15 is installed on the front side of the sampling box 14. The air outlet end of the air pump 15 is connected to the bottom space of the sampling box 14 through an air injection pipe 16. The air injection pipe 16 is provided with a solenoid valve. The two L-shaped rods 20, the external power supply, the air pump 15 and the solenoid valve form a loop through wires.

[0035] As an embodiment of the present invention, the lower end of the control box 29 is fixedly connected to a fixed plate 34, and two telescopic rods 36 are fixedly connected to the right side of the fixed plate 34. The telescopic ends of the two telescopic rods 36 are commonly fixedly connected to a push plate 37. The push plate 37 and the adjacent surfaces of the fixed plate 34 are elastically connected by two second springs 38. A second electromagnet 35 is installed on the right side of the fixed plate 34, and an L-shaped push block is fixedly connected to the lower end of the push plate 37. The push plate 37 is made of magnetic material, and the second electromagnet 35 repels the adjacent surfaces of the push plate 37 with the same charge after being energized.

[0036] In the present invention, the storage barrel of the cosmetics is placed in the sampling chamber 3, and the driving motor 7 can be started at this time. The operation of the driving motor 7 drives the reciprocating screw 8 to rotate through the two bevel gears 9, so that the moving block 10 drives the sampling box 14 to move downward first and then upward;

[0037] When the sampling box 14 moves downward, the sampling tube 23 enters into the cosmetic liquid. When the moving block 10 contacts the contact block 6 located above, the first electromagnet 17 is energized. After the first electromagnet 17 is energized, it generates an attractive force on the piston 22, so that the piston 22 moves upward, thereby increasing the bottom space of the sampling box 14 and reducing the air pressure, so that the cosmetics at this depth enter into the sampling box 14.

[0038] As the moving block 10 continues to move downward, when the moving block 10 is not released from the contact block 6 located above, the first electromagnet 17 is de-energized, so that the piston 22 moves back under the elastic action of the first spring 18, so that the extracted cosmetics are pressed into the serpentine tube 25 through the hose 11, and then fall into the sampling dish 32 through the short tube 26 and the discharge tube 27;

[0039] When the piston 22 moves back, the two L-shaped rods 20 are in contact, so that the air pump 15 is operated. The air pump 15 injects gas into the sampling box 14 and then flows in the hose 11 and the serpentine tube 25, so as to quickly press out the cosmetics sampled in the pipeline, so that the cosmetics sampled each time can fall completely into the sampling dish 32;

[0040] Since the multiple sterilizing lamps 24 are always in operation, the cosmetics flowing in the serpentine tube 25 are exposed to the sterilizing lamps 24 for a longer time, so that the cosmetics can be sterilized well, thereby preventing the microorganisms from affecting the subsequent detection of the cosmetics.

[0041] It is worth mentioning that since the moving block 10 moves up and down once, the moving block 10 contacts the two contact blocks 6 twice, so four samples are taken. Since the pages in the storage barrel change after each sampling, the depths of the cosmetics taken four times are completely different, so that better comparison can be made during cosmetic testing.

[0042] When the piston 22 moves downward, the sample is pressed into the sampling dish 32. When the piston 22 moves upward, the top space of the sampling box 14 is reduced and the air pressure is increased, so that the gas in the top space of the sampling box 14 enters the right space of the control box 29 through the connecting tube 13, thereby increasing the gas in the right space of the control box 29 and increasing the air pressure, so that the slider 39 drives the rack 40 to move left, and the rotating gear 19 drives the vertical rod 30 and the turntable 31 to rotate ninety degrees. When the piston 22 moves downward, the top space of the sampling box 14 is increased and the air pressure is reduced, so that the gas in the right space of the control box 29 enters the sampling box 14, and then the slider 39 drives the rack 40 to move right. Due to the setting of the one-way bearing, the rotating gear 19 will not drive the vertical rod 30 to rotate. By using the above method, the cosmetic liquid sampled four times enters four different sampling dishes 32;

[0043] When the liquid is completely discharged into the sampling dish 32 each time the sampling is taken, the pressure sensor will generate an electrical signal and transmit it to the controller (reaching the trigger signal of the controller). The controller controls the second electromagnet 35 to be energized, thereby generating a repulsive force on the push plate 37, causing the push plate 37 to move right, pushing the sampling dish 32 into the detection box 2 for detection. When the sampling dish 32 enters the inner chamber of the detection box 2, the pressure sensor no longer generates an electrical signal, thereby causing the second electromagnet 35 to be de-energized and the push plate 37 to be reset. According to the above method, the four sampling dishes 32 are pushed into the detection box 2 in turn for detection.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
