Technical Field

[0001] The utility model relates to the technical field of eye cream detection, in particular to a detection device for the permeability and absorption effect of eye cream. Background Technique

[0002] Eye cream belongs to skin care cosmetics, which has the effects of moisturizing and tightening the eye skin. In addition to relieving dark circles and eye bags, it also has the effects of improving wrinkles and fine lines. It can relieve problems such as dark circles, eye bags, crow's feet and milia caused by ultraviolet radiation, long-term computer radiation, and bad living habits. When producing eye cream, it is often necessary to detect its permeability and absorption effect through a diffusion cell.

[0003] The "transdermal positioning structure of a transdermal diffusion cell" disclosed in its application number "CN202223418133.X" "comprises a positioning seat and a positioning cover. The positioning cover is arranged at the upper end of the positioning seat, and the positioning cover and the positioning seat are connected and communicated through a through hole. A raised positioning ring is arranged on the surface of the top end of the positioning seat around the outer periphery of the through hole. The skin is placed on the positioning ring. The inner wall of the positioning ring is flush with the inner wall of the through hole, and the outer wall of the positioning ring is inclined; a receiving groove is opened around the outer periphery of the through hole at the bottom of the positioning cover. A sealing ring is arranged in the receiving groove. A positioning groove is opened in the center of the bottom of the sealing ring. The shape of the positioning groove is adapted to the shape of the positioning ring, so that the positioning cover realizes the clamping and positioning of the membrane or skin by pressing and matching the raised positioning ring on the positioning seat through the sealing ring." In the utility model, a raised positioning ring is arranged on the top of the positioning seat. By matching the positioning ring with the sealing ring at the bottom of the positioning cover, the skin can be tightly pressed and positioned, and the middle part of the skin is in a flat state, thus effectively preventing the central collapse phenomenon of the skin due to relaxation after long-term soaking.

[0004] However, the above method still has the following defects: The skin can be tightly pressed through the positioning ring, but the positioning ring is installed in a snap-fit manner and is easily detached under horizontal thrust, with poor stability. It is prone to deformation after long-term use, which will reduce the snap-fit effect and cause the loosening of the positioning cover, and has poor durability. Content of the Utility Model

[0005] The purpose of the utility model is to provide a detection device for the permeability and absorption effect of eye cream, so as to solve the problem that the positioning ring is installed in a snap-fit manner and is easily detached under horizontal thrust and has poor stability mentioned in the above background technique.

[0006] The present utility model provides the following technical solution: an eye cream permeability and absorption effect detection device, including a receiving pool and an upper cover. A support assembly is provided at the bottom end of the receiving pool. A threaded tube is fixedly connected to the top end of the receiving pool through a support ring.

The threaded cover is fixedly connected to the upper cover. A glass sheet is provided at the top end of the upper cover.

[0007] As a preferred technical solution of the present utility model, the support assembly includes a support plate and an anti-slip pad. The top end of the support plate is fixedly connected to the bottom end of the receiving pool. The diameter of the support plate is larger than that of the receiving pool. An anti-slip pad is fixedly provided at the bottom end of the support plate. One side of the top end of the support plate is fixedly connected to a clamping block through a cushion block.

[0008] As a preferred technical solution of the present utility model, the clamping block is snap-connected to a clamping sleeve. One side of the bottom end of the clamping sleeve is fixedly provided with a positioning plate. Two positioning holes are formed on the surface of the positioning plate.

[0009] As a preferred technical solution of the present utility model, a clamping strip is fixedly provided at the top end of the sealing ring. A recess is formed at the bottom end of the pressing ring. The clamping strip is snap-connected to the pressing ring through the recess.

[0010] As a preferred technical solution of the present utility model, the pressure transmission assembly includes a retaining ring. The bottom end of the retaining ring is slidably connected to the top end of the threaded cover through a plurality of guide posts. A spring is sleeved on the surface of the guide post.

The threaded cover is fixedly connected to the upper cover through the installation opening. A plurality of anti-slip strips are provided on the surface of the threaded cover.

[0014] Compared with the prior art, the present utility model has the following beneficial effects:

[0015] The detection device for the permeability and absorption effect of this eye cream can carry a skin model through a support ring. By tightening the threaded cap and connecting the threaded cap to the threaded tube, the upper cover can be fixed. When subjected to a horizontal thrust, the upper cover can be prevented from loosening and falling off. The threaded cap can transfer the pressure to the pressure ring through a pressure transfer component. As the threaded cap is continuously tightened, the pressure exerted on the skin model by the pressure ring can be increased, and the skin model can be uniformly stressed. The sealing ring at the bottom of the pressure ring enters the pressing groove to tighten the skin model and maintain its sealing performance, improving the stability of the upper cover and the skin model, and having good durability. By loosening or tightening the threaded cap, the magnitude of the pressure applied to the skin model can be adjusted. The receiving pool can be supported by a support component, improving the stability of the receiving pool, and preventing the receiving pool from displacing during the detection process.
