Description

Technical Field

[0001] This utility model belongs to the field of cosmetic testing equipment, and specifically relates to an auxiliary testing device for human evaluation of cosmetics. Background Technology

[0002] With the release of the "Standards for Evaluating Cosmetic Efficacy Claims," ​​the evaluation of cosmetic efficacy has received increasing attention, and the demand for testing is growing daily. Human efficacy evaluation trials must be conducted under laboratory conditions, according to prescribed methods and procedures, and the process must adhere to ethical principles to protect the rights of participants to the greatest extent possible.

[0003] Currently, human efficacy evaluation trials often require selecting the arm as the test site, exposing it for an extended period under specified environmental conditions, with different follow-up points to collect skin parameters again. On the one hand, the skin exposed to the environment may experience discomfort (such as a cold sensation); on the other hand, to ensure that the sample applied to the skin is not scratched or damaged, participants must constantly ensure that their long-sleeved clothing is rolled up and that their arms are kept in a position where they are not touched, which greatly restricts limb movement.

[0004] Patent CN219049091U discloses a thermal cover for human efficacy testing, which keeps the limbs warm while preventing cosmetics from being scratched. However, the method of wrapping the limbs with the flexibility of the thermal fabric and securing it with Velcro is rather cumbersome, requiring the thermal cover to be removed multiple times when collecting parameters at follow-up points such as 1h, 2h, and 4h. In addition, the disclosure uses silicone strips to support the metal mesh above the coating area and to increase the friction with the skin to prevent slippage and detachment. On the one hand, there is a risk that the support of the silicone strips may not be fixed, and the metal mesh may be compressed and collided with by external forces due to the participant's limb movements, contaminating the sample in the coating area. On the other hand, the silicone strips may also cause discomfort to the participants due to prolonged binding of the limbs. Finally, the disclosure does not address the connection between the thermal cover and the participant's long-sleeved clothing. Utility Model Content

[0039] like Figure 1 , 2 As shown, this utility model provides an auxiliary testing device for human evaluation of cosmetics, including a protective structure 1, a limiting structure 2, a base 3, and a connecting structure 4; the protective structure 1 is mounted on the base 3 through the connecting structure 4 and connected to the human body through the limiting structure 2.

[0040] The following section describes the device in detail using the example of a cosmetic testing site on the arm. The protective structure 1 includes a main body 11, a breathable layer 12, and a protective layer 13. The main body 11 is fitted onto the arm, with a gap between it and the testing site to prevent contact. Breathing vents are provided on the side wall of the main body 11 for collecting and evaluating test results. The breathable layer 12 is positioned on the main body 11 corresponding to the breathing vents, ensuring that heat exchange between the skin and the environment in the testing area is not affected. The protective layer 13 covers the outer surface of the breathable layer 12 away from the arm and is connected to the main body 11, effectively preventing dust and moisture from entering the interior space of the main body 11 when not in use.

[0041] In some embodiments, the main body 11 is a cylindrical structure with at least one open end to facilitate arm insertion. The internal dimensions of the cylindrical structure are larger than the cross-sectional dimensions of the arm, creating a gap between the main body 11 and the test site. The main body 11 can keep the participant's arm warm, preventing discomfort caused by prolonged exposure. Optionally, the main body 11 is made of rigid plastic, which is not easily deformed by bumps or impacts, thus not affecting the test results; at the same time, rigid plastic can also prevent deformation due to temperature differences. Optionally, both ends of the cylindrical structure are open, with the vents corresponding to the cosmetic test site.

[0042] In some embodiments, the breathable layer 12 has a multi-mesh structure. Optionally, the breathable layer 12 is made of polyester fiber and is covered above the air vent of the body 11 by hook and loop fasteners. Polyester fiber has good breathability, strength and abrasion resistance, and can effectively protect the area where the cosmetic sample is applied from damage.

[0043] In some embodiments, the outer surface of the protective layer 13 is provided with a waterproof and stain-resistant coating to further enhance the protective effect. The protective layer 13 is detachably connected or hinged to the main body 11. In the working state, the protective layer 13 is offset from the air vent of the main body 11; in the non-working state, the protective layer 13 covers the breathable layer 12 and completely blocks the air vent of the main body 11.

[0044] Optionally, the protective layer 13 is a flexible structure, with one end fixedly connected to the main body 11 and the opposite end detachably connected to the main body 11 via a hook and loop fastener.

[0045] This device offers two usage methods: one is to peel back the breathable layer 12 and protective layer 13 while the participant's arm is inside the protective structure 1, and collect data directly at the test site through the vent; the other is to collect data after the arm is extended by adjusting the bolt 21. The data collection method can be flexibly selected according to experimental needs.

[0046] The limiting structure 2 includes an adjusting bolt 21 and a skin-adhesive strip 22. The adjusting bolt 21 is arranged along the transverse axis on the side wall of the main body 11 and is threadedly connected to it, with its inner end extending into the main body 11. The skin-adhesive strip 22 is arranged at the inner end of the adjusting bolt 21. When the adjusting bolt 21 is rotated, its inner end drives the skin-adhesive strip 22 to move closer to or away from the arm, thereby realizing the connection and separation between the main body 11 and the arm, which can adapt to the individual circumstances of different participants.

[0047] In some embodiments, the skin-adhesive strip 22 is a silicone strip. The silicone strip, in conjunction with the main body 11, effectively prevents long-sleeved clothing from sagging and avoids contact between the sample application area and the clothing. The contact surface between the skin-adhesive strip 22 and the arm is curved to better adapt to the arm's shape. The connection point on the main body 11 corresponding to the adjusting bolt 21 is thickened to ensure the stability of the threaded connection. Optionally, the limiting structure 2 is located on the upper sidewalls at both ends of the main body 11 and is offset from the cosmetic testing area.

[0048] The base 3 is used to place the protective structure 1, on which a bracket 31 is set. The bracket 31 is used to place electronic devices and is adapted to the position of the participant's hands, allowing the participant to browse the electronic devices and relax during the test.

[0049] In some embodiments, the bracket 31 and the base 3 are detachably connected, and can be connected by plug-in or magnetic connection, so as to facilitate the adjustment of the position of the bracket 31 according to the position of the participant's hand.

[0050] like Figure 3 , 4As shown, the connecting structure 4 includes a socket 41, a slide rail 42, a slider 43, and a pin 44. The sockets 41 are spaced apart on the base 3. The slide rail 42 is arranged along the length direction at the bottom of the main body 11. The slider 43 is slidably arranged in the slide rail 42. The pin 44 is arranged on the slider 43 and is inserted into the socket 41 to realize the connection between the base 3 and the protective structure 1.

[0051] In some embodiments, the base 3 is provided with two rows of sockets 41, each row including multiple sockets 41 spaced apart; each slide rail 42 is provided with two sliders 43, and the pins 44 of the two sliders 43 are respectively connected to different rows of sockets 41 to fix the position of the protective structure 1.

[0052] In some embodiments, the latch 44 is a push-button self-spring latch, which is disposed inside the slider 43, with its button extending to the outside of the slider 43 for easy operation by the operator. A cavity is provided on the slider 43 to accommodate the push-button self-spring latch. The latch 44 can be an existing push-button self-spring latch, so it will not be described in detail here.

[0053] Optionally, the slide rail 42 is closed at both ends to prevent the slider 43 from detaching from the slide rail 42.

[0054] When using this device, select the appropriate socket 41 according to the participant's own situation and plug the pin 44 into it; then, open the protective layer 13 to expose the breathable layer 12; the participant puts the bare arm marked with the test area into the main body 11 and rotates the adjusting bolt 21 to press the skin strip 22 tightly against the participant's skin; the participant can place the electronic device on the bracket 31 and use their fingers to adjust the electronic device to relax and soothe the state.

[0055] 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.
