[0002] Sponge is a porous material with good water absorption and can be used to clean items. The commonly used sponges are made of wood cellulose fibers or foamed plastic polymers. In addition, there are also natural sponges made from sponge animals. Among these sponge products, slow-rebound sponges are also called inert sponges, memory sponges, low-rebound sponges, slow-rebound cotton, and zero-pressure sponges. According to different processes, it can be divided into polyether foaming series and MDI molding series. Slow-rebound sponge was originally designed and developed by NASA for the space program as a high-tech material. When the slow-rebound sponge is deformed by external pressure, it will not rebound immediately, but will be delayed for a few seconds and slowly restored.

[0003] In the prior art, sponges lack certain toughness when used, have simple structures, and still have insufficient rebound speed, low rebound speed, and small buffering, which easily reduces the comfort of products made of slow-rebound sponges, resulting in reduced equipment efficiency and reduced practicality; secondly, sponges are flammable items with a very low ignition point. A small flame may cause the entire sponge to burn. If the fire spreads too quickly, it will cause a large fire, resulting in reduced safety of sponge products. Long-term use cannot be properly cleaned, and mites are prone to breed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 A slow rebound sponge comprises a breathable protective layer 1, the breathable protective layer 1 is provided with air holes 11 on the sides thereof, the front of the breathable protective layer 1 is made of wear-resistant material, a cavity is provided in the center of the breathable protective layer 1, and the air groove 2 is provided on the inner surface of the cavity and connected to the air holes 11 distributed on the side walls thereof. An activated carbon absorption layer 12 is provided in the center of the breathable protective layer 1, and the activated carbon absorption layer 12 can effectively filter and remove harmful substances in the air, providing a healthier and fresher sleeping environment.

[0022] The activated carbon layer is cylindrical, and its diameter is equal to the inner diameter of the connecting hole in the buffer layer 4. The number of the breathable protective layer 1 is two, and the number of the partitions is twelve, which are symmetrically distributed. The partition layer 42 is made of a material with good fire resistance. The wall surface of the connector 41 is evenly provided with breathable holes 11. The outer periphery of the fixing layer 43 is provided with a viscous layer 3.

[0023] The breathable protective layer 1 has breathable grooves 2 distributed around the activated carbon center, and the breathable grooves 2 intersect with each other to form breathable mesh grooves. Due to the arrangement of the breathable protective layer 1, the rebound sponge has good air permeability, which can keep the inside of the mattress dry and clean.

[0024] The breathable protective layer 1 is connected to the buffer layer 4 through the activated carbon layer. The buffer layer 4 includes a connector 41. A connecting hole is provided in the center of the connector 41. A partition layer 42 extends outward from all sides of the connector 41. The partition layer 42 is connected to the fixing layer 43. The fixing layer 43 and the partition layer 42 are connected to each other to form a buffer groove. A high elastic sponge is provided in the buffer groove. The high elastic sponge and the partition layer 42 are tightly fitted to form the buffer layer 4. The structural design of the buffer layer 4 makes this sponge have excellent buffering performance, can disperse the weight of the body, reduce pressure, and provide comfortable support. The elasticity of the high elastic sponge can adapt to various postures and movements of the body, providing a good sleeping experience. The high elastic sponge is tightly fitted to the partition layer 42, and the fit is high, which further improves the comfort.

[0025] Working principle: By adding a high-elastic sponge in the partition, this type of sponge can be made tighter in different interiors. At the same time, the external protective shell uses a softer sponge, so that this type of sponge product can have better chronic rebound through the inside during use. At the same time, the external protective layer can provide suitable softness to the user. At the same time, the triangular groove formed by the partition and the fixed layer 43 is interconnected to form a triangular groove, which can better help the high-elastic sponge arranged therein to rebound. Through the connection between the air groove 2 and the air hole 11, the sponge can have better air permeability. During cleaning, the water flow can quickly flush out the odor generated by long-term use in the sponge through the air groove 2. The fireproof material used in the partition layer 42 can block the burning of the sponge during combustion, so that the overall flammability of the sponge is greatly reduced.
