[0030] The following is only a preferred embodiment of the utility model, and does not limit the protection scope of the utility model.

[0031] A kind of to improve the wrinkle resistance mould cup, as shown in Fig. Figures 1 to 4 From outside to inside, it includes outer wrapping layer 1, outer elastic layer 2, central elastic support layer 3, inner elastic layer 4 and inner skin-friendly layer 7, central elastic support layer 3 includes support ring 31, inner elastic net 32 and outer elastic net 33, inner elastic net 32 is arranged in the inner circle of support ring 31, outer elastic net 33 is arranged on the outside of support ring 31, inner elastic net 32 includes multiple inner elastic strips 321 that cross horizontally and longitudinally, outer elastic net 33 includes multiple outer elastic strips 331, the inner end of each outer elastic strip 331 is shaped on the outer side of support ring 31, the outer end of each outer elastic strip 331 extends towards the edge of mould cup and forms the radial outer elastic net 33, the cross-sectional shape of outer elastic layer 2 is wave-shaped, and outer energy storage cavity 21 is formed between wave crest and wave trough, inner elastic layer 4 is provided with multiple first guide grooves 41 and multiple second guide grooves 42 on the side towards central elastic support layer 3, and each first guide groove 41 is respectively arranged with each second guide groove 42.

[0032] The traditional mould cup only improves the anti-wrinkle performance by setting a single anti-wrinkle layer, and mainly realizes the anti-wrinkle by adopting a material with high elasticity, the anti-wrinkle performance is poor, and bidirectional rapid recovery cannot be realized, while the inner elastic net 32 of the central elastic supporting layer 3 can elastically support the peak and valley regions of the mould cup, the radial outer elastic net 33 can elastically support the periphery of the mould cup, a partitioned elastic supporting structure is formed, the inner and outer elastic nets are deformed in coordination to disperse stress when being pressed, and rapid partitioned reset is realized after release; the wave-shaped section of the outer elastic layer 2 forms an outer energy storage cavity 21, stores elastic potential energy when being pressed, and rapidly recovers to the original state through the wave peak and wave valley structure when being released, and the plastic deformation probability is reduced; the first guide groove 41 and the second guide groove 42 of the inner elastic layer 4 form a net-shaped stress guide channel, converts local stress into distributed deformation, and avoids wrinkle generation.

[0033] Specifically, the intersection of each first guide groove 41 and each second guide groove 42 is provided with a stress release hole 43 penetrating through the inner elastic layer 4. The intersection of the first guide groove 41 and the second guide groove 42 is a stress concentration point, and the stress release hole 43 is arranged at the point to actively release local stress and avoid micro-crack expansion. The hole structure guides controllable deformation of the material, and converts linear stress into annular dispersion.

[0034] Specifically, the depth of each first guide groove 41 and each second guide groove 42 is 30-50% of the thickness of the inner elastic layer 4, and the inner elastic layer 4 is made of silica gel. The depth of the first guide groove 41 and the second guide groove 42 is controlled to be 30-50%, which can ensure the stress guide effect and avoid the decrease of structural strength caused by too deep grooves. The high resilience of the silica gel material enables the first guide groove 41 and the second guide groove 42 to quickly recover to the original state after being pressed, avoiding permanent deformation.

[0035] Specifically, the inner part of each outer elastic layer 2 is embedded with an obliquely woven reinforcing net 22, the weaving angle of the reinforcing net 22 is 45°±5°, and the wire diameter of the reinforcing net 22 is 0.05-0.1mm. The 45° obliquely woven reinforcing net 22 matches the direction of human motion to resist shear stress and improve tear strength, and the relatively thin wire weaving of the reinforcing net 22 ensures the reinforcing effect while not increasing the material hardness, maintaining the flexibility of the wave-shaped structure.

[0036] Specifically, the outer wrapping layer 1 is provided with inwardly protruding rhombic protrusions 11 on the side facing the outer elastic layer 2, and the third guide groove 12 is formed between adjacent protrusions 11. The outer wrapping layer 1 is made of a dacron / spandex blended fabric.

[0037] The convex part 11 in the shape of a rhombus forms a convex point supporting structure, disperses external pressure and improves comfort; the third guide groove 12 forms a composite flow guide channel with the outer energy storage cavity 21 of the outer elastic layer 2, improving the air permeation efficiency.

[0038] Specifically, the inner skin-friendly layer 7 is provided with a plurality of sweat discharge micropores penetrating the inner skin-friendly layer 7, and the inner skin-friendly layer 7 is provided with an adsorption layer 5 between the inner skin-friendly layer 7 and the inner elastic layer 4, and the adsorption layer 5 is an activated carbon fiber felt. The pore size of the sweat discharge micropore is 50-100 μm, forming a one-way wet guide channel, improving the sweat discharge efficiency, avoiding the occurrence of a stuffy phenomenon, improving the comfort, and the activated carbon fiber felt can adsorb and eliminate the odor of sweat, while avoiding reverse osmosis of sweat.

[0039] Specifically, an antibacterial layer 6 is arranged between the adsorption layer 5 and the inner skin-friendly layer 7, and the antibacterial layer 6 is a bamboo fiber woven layer, and the weaving density of the bamboo fiber woven layer is 120-150 meshes. The high-density bamboo fiber woven layer can physically block the penetration of bacteria and improve the bacteriostasis rate. And the natural hollow structure of the bamboo fiber forms a capillary effect to assist the adsorption layer to quickly discharge moisture.

[0040] Specifically, the outer surface of the bamboo fiber woven layer is coated with an antibacterial coating. The antibacterial coating is a nano-silver coating, which forms a double antibacterial mechanism with the bamboo fiber woven layer and improves the long-acting property of bacteriostasis. The antibacterial coating can cover the fiber gap to prevent bacteria from breeding in the woven pores.

[0041] Specifically, the outer diameter of the inner end of the outer elastic strip 331 is greater than the outer diameter of the outer end. The thickened design of the inner end enhances the anchoring strength, increases the connection area, avoids the outer elastic strip 331 from falling off the support ring 31, the outer end of the outer elastic strip 331 is a free end, and the tapered structure of the outer end reduces the edge stiffness, so that the edge of the mold cup is more fitted to the body curve and has stronger elasticity, while the inner elastic strip 321 has fixed ends at both ends and is interwoven, which can provide stronger support, thereby realizing the partitioned elastic support.

[0042] The above is only a preferred embodiment of the present application, and for those skilled in the art, according to the idea of the present application, the specific implementation mode and application range can be changed, and the content of the specification should not be understood as limiting the present application.
