Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing equipment technology, and in particular to a microbial testing device for skin care products. Background Technology
[0002] As people pay increasing attention to the quality and safety of personal care products, the skincare industry is placing increasingly stringent requirements on microbial testing. Microbial contamination can lead to product spoilage, skin allergies, and even harm to human health. Therefore, accurate and efficient microbial testing has become a core element in ensuring product quality. In actual testing, skincare products come in a variety of packaging forms, from plastic bottles and glass bottles to tubes, with significant differences in container size and shape. The way different types of sample containers are fixed in the testing equipment directly affects the accuracy and stability of the test results. Traditional testing equipment has many limitations in sample fixation and cannot meet diverse testing needs. Therefore, skincare microbial testing equipment that can adapt to different sample containers and achieve reliable positioning has become an urgent technological need in the industry.
[0003] Existing skincare product microbial testing equipment mostly uses fixed-size slots or clamps for sample fixation. Some equipment uses pre-set molds or grooves to embed sample containers and uses mechanical limiting to achieve fixation. Other equipment uses screw fastening or snap-on fixing methods, requiring operators to manually adjust the screw tightness or snap-on position to fix the sample.
[0004] However, existing skincare product microbial testing equipment has the problem of difficulty in effectively limiting the position of different sample containers. In actual testing work, due to the lack of flexibility and adaptability of the fixing structure of traditional equipment, it is impossible to ensure the stability of the sample during the testing process when faced with diverse skincare product sample containers. When testing skincare products packaged in small-capacity ampoules or irregularly shaped tubes, traditional fixing slots or clamps cannot fit tightly against the container surface, which can easily lead to sample tilting, shaking, or even falling off. The instability of the sample can cause data deviation and instrument misjudgment during the testing process, which seriously affects the accuracy and reliability of the test results. Therefore, a skincare product microbial testing device is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a skin care product microbial detection device, which aims to improve the problem that the existing technology is prone to sample tilting, shaking or even falling off during the detection process, and the instability of the sample will lead to data deviation during the detection process.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A skincare product microbial detection device includes a detection machine, a display screen inside the detection machine, a detection head inside the detection machine, a fixing plate fixedly connected inside the detection machine, a storage seat fixedly connected inside the fixing plate, a clamping assembly inside the storage seat, and a liquid injection assembly inside the detection machine.
[0008] The clamping assembly includes a locking block, which is slidably connected inside the storage base. The storage base has a sliding groove, and the locking block is slidably connected inside the sliding groove. A support column is fixedly connected inside the storage base, and the locking block is slidably connected to the outer wall of the support column. A spring is sleeved on the outer wall of the support column, and both ends of the spring are fixedly connected inside the locking block and the storage base, respectively.
[0009] As a further description of the above technical solution:
[0010] The liquid injection assembly includes a liquid injection tube and a liquid injection head. The outer wall of the liquid injection tube is fixedly connected to the inside of the testing machine, and the top end of the liquid injection head is fixedly connected to the bottom end of the liquid injection tube.
[0011] As a further description of the above technical solution:
[0012] An infusion tube is fixedly connected to the outer wall of the injection tube, and a connecting tube is fixedly connected to the outer wall of the infusion tube.
[0013] As a further description of the above technical solution:
[0014] A liquid storage box is fixedly connected to the top of the connecting pipe, and a liquid addition pipe is fixedly connected to one side of the liquid storage box.

[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, by placing the skin care product sample container in the holder, the locking block is forced to slide into the holder. Under the action of the spring force, the locking block slides along the groove and the support column. The elasticity of the spring causes the locking block to stick tightly to the outer wall of the sample container, providing buffering and continuous clamping force. This achieves the effect of effectively limiting the position of different sample containers, solving the problem that samples are prone to tilting, shaking or even falling off during the detection process. The instability of the samples can lead to data deviations during the detection process, thereby improving the applicability of the detection equipment.
[0023] 2. In this utility model, by activating the cylinder, the piston rod at its output end pushes the piston plate to slide inside the infusion tube and the injection tube, transporting the liquid in the storage box to the injection tube through the connecting tube and the infusion tube, and finally dripping it onto the skin care product sample through the injection head. This achieves the effect of conveniently adding reagents to skin care products in a quantitative manner, solving the problems of cumbersome operation, difficulty in accurately controlling the amount added, and inability to flexibly adapt to the reagent addition requirements of different test items when adding reagents in traditional testing equipment, thereby improving the flexibility of the testing equipment.

[0033] The clamping assembly includes a locking block 7, which is slidably connected inside the storage base 4. The storage base 4 has a sliding groove 6 inside, and the locking block 7 is slidably connected inside the sliding groove 6. The locking block 7 is slidably connected inside the sliding groove 6 inside the storage base 4, which facilitates the adjustment of its position according to samples of different sizes.

A spring 9 is sleeved on the outer wall of the support column 8, and the two ends of the spring 9 are fixedly connected to the locking block 7 and the storage base 4, respectively. The spring 9 can adjust the fixing force of the locking block 7 through its elasticity, so as to avoid damage to the sample container due to excessive pressure, and also enhance the operability of the clamping assembly.
[0034] Reference Figure 1 , Figure 4 and Figure 5The liquid injection assembly includes an injection tube 10 and an injection head 11. The outer wall of the injection tube 10 is fixedly connected to the inside of the testing machine 1. The top end of the injection head 11 is fixedly connected to the bottom end of the injection tube 10. An infusion tube 12 is fixedly connected to the outer wall of the injection tube 10 for transporting liquid from the storage box 14 to the sample. A connecting tube 13 is fixedly connected to the outer wall of the infusion tube 12. The top end of the connecting tube 13 is fixedly connected to the storage box 14. A liquid addition tube 15 is fixedly connected to one side of the storage box 14. A flange 16 is fixedly connected to one end of the infusion tube 12. A flange 17 is fixedly connected to one end of the flange 16. A support frame 18 is fixedly connected, and a cylinder 19 is fixedly connected to one end of the support frame 18.

[0035] Working principle: When using this skin care product microbial detection device, the skin care product sample container is first placed in the storage base 4. During this process, the locking block 7 will slide into the storage base 4 under the force of the spring 9. Under the action of the spring 9, the locking block 7 slides along the slide groove 6 and the support column 8. At the same time, through the elasticity of the spring 9 itself, the locking block 7 is pressed tightly against the outer wall of the skin care product sample container. The spring 9 provides buffering and continuous clamping force to ensure that the sample is placed stably during the detection process and avoids the impact of shaking on the detection results. Thus, it achieves the effect of effectively limiting the position of different sample containers.
[0036] When it is necessary to add reagents to skin care products, the required liquid reagents can be added to the storage box 14 through the liquid addition tube 15. When adding, the cylinder 19 is activated, and the piston rod 20 at its output end pushes the piston plate 21 to slide in the infusion tube 12 and the injection tube 10, so that the liquid in the storage box 14 is transported to the injection tube 10 through the connecting tube 13 and the infusion tube 12. Finally, the liquid is dripped onto the skin care product sample by the injection head 11 to complete the reagent addition operation, thereby achieving the effect of conveniently adding reagents to skin care products in a quantitative manner.
