Referring to fig. 1 to 4, a flexible toilet seat 1 of an embodiment includes a base plate 100, a first popcorn foamed layer 200 covering an upper surface and sides of the base plate 100, a second popcorn foamed layer 300 covering an upper surface and sides of the first popcorn foamed layer 200, and a surface layer 400 covering an upper surface and sides of the second popcorn foamed layer 300. Wherein the density of the second popcorn foam layer 300 is less than the density of the first popcorn foam layer 200.

The bottom plate 100 may be a conventional seat ring structure, and has an integrally formed top wall and side walls formed by bending two sides of the top wall downward, and is made of thermosetting material plates such as SMC plate, carbon fiber plate, BMC plate, urea-formaldehyde resin plate, etc.; or engineering plastic plate such as PBT, PA, PET, PEEK, PPS, PC/ABS, POM, POK, PPO, ASA, PPSU, PSU, PES, etc.; the preferred SMC board, carbon fiber board, BMC board, urea-formaldehyde resin board can reach thinner, lighter stronger effect. Conventionally, four mounting holes for foot pads are distributed on the bottom plate 100. The thickness of the base plate 100 is, for example, 1.5mm, the width is slightly narrower than the width of the integrated seat ring by 5mm to 10mm, and the width of each side is 2.5mm to 5.0 mm. That is, the upper surface and both sides of the bottom plate 100 are covered by the popcorn foam layer and the surface layer, and the seam is located at the back of the product, so that a better appearance effect can be achieved, and a waterproof effect can be achieved.

The first popcorn foamed layer 200 is made of a material having a relatively high density, so that an even stress distribution can be ensured. The first popcorn foaming layer 200 is made of E-TPU popcorn material, nylon popcorn material, TPEE popcorn material or other thermoplastic foaming material particles. Wherein the E-TPU popcorn or nylon popcorn or TPEE popcorn material is made by a supercritical fluid foaming processThe fully closed-hole material and the fully closed-hole foaming material can provide more excellent rebound resilience and improve the durability of the seat ring. The first popcorn foamed layer 200 has a density of 0.70g/cm³～0.90g/cm³Specifically, for example, the density of the PVC micro-foaming material provided by the Yanyi Haoyuan plastics Co., Ltd is 0.80g/cm³. The first popcorn foamed layer 200 includes a first top wall 200a and a first side wall 200b, for example, the first top wall 200a has a thickness of 8mm, and the first side wall 200b has a thickness of 2 mm.

The second popcorn foam layer 300 uses a material of lower density to provide a soft sitting feeling. Similarly, the second popcorn foam layer 300 can be E-TPU popcorn material, nylon popcorn material, TPEE popcorn material, or other thermoplastic foam particles. The density of the second popcorn foamed layer 300 is 0.20g/cm³～0.60g/cm³. The second popcorn foamed layer 300 includes a second top wall 300a and a second side wall 300b formed by extending downward from both sides of the second top wall 300a, for example, the thickness of the second top wall 300a is 5mm, and the thickness of the second side wall 300b is 2 mm.

To further improve the comfort of use, referring to fig. 3 and 4, the second popcorn foaming layer 300 is formed by combining components with different densities along the circumferential direction of the seat ring, and comprises a sitting bone part 310, an ischial front part 320, an ischial rear part 330 and a transition part 340, wherein the transition part 340 is connected between the sitting bone part 310 and the ischial front part 320 and between the sitting bone part 310 and the ischial rear part 330, the density of the transition part 340 is between the sitting bone part 310 and the ischial front part 320, and the density of the transition part 340 is between the sitting bone part 310 and the ischial rear part 330. For example, the sitting bone part and the transition part are made of TPU foamed materials provided by Fujian shoe materials Co., Ltd and have respective densities of 0.20g/cm³And a sum of 0.20 to 0.40g/cm³The front part and the back part of the ischia adopt high foaming TPE materials provided by gallery Shufu plastics, and the density is 0.40-0.60 g/cm³. As a general knowledge, the ischial portion referred to herein is the area of the toilet seat that contacts the ischial portion of the user when the user is using the toilet. By the structural design, on one hand, the structure accords with the principle of human engineering, and provides an area distribution structure adapting to the human body structureSo as to obtain better use comfort; on the other hand, the integrity of the seat ring is ensured to obtain proper stress distribution, and the problems of cracking and the like caused by local sudden change are avoided.

The surface layer 400 provides skin-friendliness, resistance to yellowing, and stain resistance. The surface layer 400 is made of TPE film, TPR film, TPV film, TPU film, polyolefin film, PVDF film, PVF film, polyamide film, silica gel leather film, ABS film, etc.; the TPV film is preferable, has the advantages of good skin touch, yellowing resistance, stain resistance and aging resistance, and has the thickness of 0.03-0.5 mm. The surface layer 400 also extends to be attached to the back of the base plate 100 so that the seams of the product are on the back, ensuring overall performance and appearance consistency.

During manufacturing, the popcorn materials with different densities can be respectively filled into corresponding molds, semi-finished products with corresponding shapes of all the components can be obtained through known modes such as hot pressing and the like, then the semi-finished products of all the components are filled into a final forming mold, the composite structure of a first popcorn foaming layer and a second popcorn foaming layer is obtained through known processes such as steam hot pressing or adhesive forming and the like, the composite structure is coated on the upper surface and the side surface of the base plate through an adhesive process or a buckle structure and the like, then the surface layer is coated on the upper surface and the side surface of the high-resilience foaming layer and the base plate through a 3D VOF process, an injection molding process or a TOM process, and the seam at the back of the seat ring product needs to be subjected to high-temperature welding treatment so that the skin-friendly, yellow-resistant and stain-resistant surface layer and the base plate are integrated at the seam.
