Description

Technical Field

[0001] The utility model relates to the technical field of sponges, in particular to a high-toughness sponge. Background Art

[0002] Sponge is a porous material with good water absorption and can be used to clean items. Commonly used sponges are made of wood cellulose fibers or foamed plastic polymers. There are also natural sponges made from sponge animals, and synthetic sponges made of other materials, including low-density polyether (non-absorbent sponge), polyvinyl alcohol (highly absorbent material with no obvious pores) and polyester. The existing sponges are generally not tough and mostly rely on the sponge's own strength for support.

[0003] In response to the above problems, a Chinese utility model patent with announcement number CN219076726U discloses a high-toughness sponge, including a sponge body and a tough layer embedded in the sponge body; a fire-blocking layer embedded in the sponge body. The sponge body is composed of two upper and lower sponges, the fire-blocking layer is arranged between the two sponges, and a plurality of fire-extinguishing capsules are embedded in each sponge at intervals. Each fire-extinguishing capsule is provided with a fire extinguishing agent. In daily use, by adopting the above technical scheme and arranging the tough layer embedded in the sponge body, the sponge body is ensured to have good toughness for a long time, and the arrangement of the fire-blocking layer and the fire-extinguishing capsule prevents the fire from spreading to other places through the sponge, thereby improving safety.

[0004] However, in the above-disclosed technical solution, the toughening effect is achieved only by adding a single-layer toughness layer. Although the toughness is enhanced to a certain extent, the toughness strength is still not high enough, and the sponge does not have a toughening structure inside. At the same time, the overall protectiveness is insufficient, and the anti-odor and flame retardant effects are not good. In view of this, the present application is proposed. Utility Model Content

[0005] In order to overcome the technical defects of the prior art, the utility model provides a high-toughness sponge, which has the advantages of strong toughness, good protection effect and good cleaning ability.

[0006] The technical solution adopted by the utility model is: it includes a central fixing plate and a soft sponge layer and a hard sponge layer respectively arranged on the upper and lower surfaces of the central fixing plate, a top side of the central fixing plate is provided with a traction wire frame woven from flame-retardant and deodorizing fibers, the traction wire frame is embedded in the soft sponge layer, and the soft sponge layer is reinforced by the setting of the traction wire frame, so that when the soft sponge layer is torn and deformed, part of the pressure can be transferred to the traction wire frame to bear, thereby improving the toughness of the soft sponge layer to a certain extent and extending the service life, and the traction wire frame is a flame-retardant and deodorizing fiber, and during use, it will not stink in a humid environment, and has a good flame retardant effect when encountering a fire, and will not promote the fire, and the bottom side of the central fixing plate is provided with a scraper embedded in the hard sponge layer, and during use, the hard sponge layer can wipe off harder debris, and for some more stubborn dirt, the hard sponge layer can be pressed hard to make the scraper protrude, so as to remove the dirt more deeply.

[0007] Preferably, a dirt collection groove is provided in the hard sponge layer, so that during use of the utility model, the dirt scraped off by the hard sponge layer can enter the dirt collection groove, and will not adhere to the surface of the hard sponge layer to affect the cleaning effect. The scraping element is located in the dirt collection groove. When the hard sponge layer is subjected to strong pressure, the scraping element protrudes from the dirt collection groove. When there is stubborn dirt that cannot be cleaned by the hard sponge layer, it is only necessary to press the hard sponge layer hard to make the scraping element protrude from the dirt collection groove.

[0008] Preferably, the scraper consists of an extension rod and a wire brush, and the wire brush is fixed to the central fixing plate through the extension rod. The extension rod provides a supporting effect, so that the hard sponge layer can push out the wire brush when under pressure, thereby providing a stronger cleaning effect through the wire brush.

[0009] Preferably, the traction wire frame is composed of a plurality of U-shaped traction fibers distributed forward and backward, and a plurality of transverse traction fibers are arranged vertically between the U-shaped traction fibers. The soft sponge layer is reinforced by the U-shaped traction fibers and the transverse traction fibers to increase the lateral pressure-bearing capacity of the soft sponge layer.

[0010] Preferably, each of the U-shaped traction fibers and each of the lateral traction fibers are connected by a plurality of forward and backward traction fibers distributed left and right. The U-shaped traction of the forward and backward traction fibers is used to reinforce the lateral traction fibers, while increasing the forward and backward pressure-bearing capacity of the soft sponge layer to improve the toughness of the soft sponge layer in all directions.

[0011] Preferably, the U-shaped traction fibers, the transverse traction fibers and the forward and backward traction fibers are all flame-retardant and deodorizing fibers, which have a good protective effect.

[0012] Preferably, the flame retardant and anti-odor fiber consists of a hollow hot-melt core and an anti-odor layer wrapped on the outer wall of the hot-melt core. The hot-melt core is filled with a flame retardant filling liquid. The hot-melt core can melt at high temperature, so that the internal flame retardant filling liquid leaks out and diffuses into the soft sponge layer to achieve a good flame retardant effect.

[0013] Preferably, the anti-odor layer is made of bamboo fiber, which has good antibacterial ability and prevents bacteria from breeding and producing odor. The hot-melt core is made of polyester hot-melt fiber, which can be melted at high temperature to release the internal flame-retardant filling liquid.

[0014] The beneficial effects of the utility model are as follows: the utility model adopts the structural design of embedding a traction wire frame in the soft sponge layer, so that the traction wire frame can reinforce the soft sponge layer, so that when the soft sponge layer is torn and deformed, part of the pressure can be transferred to the traction wire frame to bear, thereby improving the toughness of the soft sponge layer to a certain extent and extending the service life; and the traction wire frame is made of flame-retardant and odor-resistant fiber, does not stink, does not support combustion, and is safer.

[0015] At the same time, the hard sponge layer can erase harder debris, and for some more stubborn dirt, the hard sponge layer can be pressed hard to make the scraping part protrude, thereby removing the dirt more deeply. Compared with existing sponges, it has strong toughness, good protection effect, good cleaning ability and high practical value. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The utility model is further described below in conjunction with the accompanying drawings:

[0024] like Figure 1-Figure 6 As shown, this embodiment provides a high-toughness sponge, including a central fixing plate 1 and a soft sponge layer 2 and a hard sponge layer 3 respectively arranged on the upper and lower surfaces of the central fixing plate 1, so that the utility model can be used on both sides when in use, one side is used for cleaning flexible substances, such as desktop dust, sewage, etc., and the hard sponge layer 3 on the other side can be used for removing impurities with strong adhesion, such as dried food residues, etc., and has a wide range of applications. A traction wire frame 4 woven from flame-retardant and deodorizing fibers is arranged on the top side of the central fixing plate 1, and the traction wire frame 4 is embedded in the soft sponge layer 2. Through the arrangement of the traction wire frame 4, the soft sponge layer 2 is reinforced, so that when the soft sponge layer 2 is torn and deformed, part of the pressure can be transferred to The traction wire frame 4 bears, thereby improving the toughness of the soft sponge layer 2 to a certain extent, and the service life is extended. At the same time, the traction wire frame 4 is a flame retardant and anti-odor fiber. During use, it will not stink in a humid environment. When encountering a fire, it has a good flame retardant effect and will not contribute to the fire. A scraper 5 embedded in the hard sponge layer 3 is provided on the bottom side of the central fixing plate 1. During use, the hard sponge layer 3 can erase harder debris, and for some more stubborn dirt, the hard sponge layer 3 can be pressed hard to make the scraper 5 protrude, thereby removing the dirt more deeply. Compared with existing sponges, it has strong toughness, good protection effect, good cleaning ability and high practical value.

[0025] Specific as Figure 2 As shown, a dirt collecting groove 301 is provided in the hard sponge layer 3, so that during use of the utility model, the dirt scraped off by the hard sponge layer 3 can enter the dirt collecting groove 301, and will not adhere to the surface of the hard sponge layer 3 to affect the cleaning effect. The scraper 5 is located in the dirt collecting groove 301. When the hard sponge layer 3 is subjected to strong pressure, the scraper 5 protrudes from the dirt collecting groove 301. When there is stubborn dirt that cannot be cleaned by the hard sponge layer 3, the hard sponge layer 3 only needs to be pressed hard to make the scraper 5 protrude from the dirt collecting groove 301, so that the scraper 5 can directly contact the stubborn dirt for higher-intensity cleaning.

[0026] like Figure 4As shown, the scraper 5 is composed of an extension rod 501 and a wire brush 502. The wire brush 502 is fixed to the central fixing plate 1 through the extension rod 501. The extension rod 501 provides a supporting effect, so that the hard sponge layer 3 can push out the wire brush 502 when under pressure, thereby providing a stronger cleaning effect through the wire brush 502.

[0027] Specific as Figure 5 As shown, the traction wire frame 4 is composed of a plurality of U-shaped traction fibers 401 distributed in the front-to-back direction, and a plurality of transverse traction fibers 402 are arranged in an upper and lower distribution between the U-shaped traction fibers 401. The soft sponge layer 2 is reinforced by the U-shaped traction fibers 401 and the transverse traction fibers 402 to increase the transverse pressure-bearing capacity of the soft sponge layer 2. Each U-shaped traction fiber 401 and each transverse traction fiber 402 are connected by a plurality of front-to-back traction fibers 403 distributed in the left and right directions. The U-shaped traction of the front-to-back traction fibers 403 is used to reinforce the transverse traction fibers 402, and at the same time, the front-to-back pressure-bearing capacity of the soft sponge layer 2 is increased to improve the toughness of the soft sponge layer 2 in all directions.

[0028] The U-shaped traction fibers 401, the transverse traction fibers 402, and the forward and backward traction fibers 403 are all flame retardant and deodorizing fibers, and have good protective effects. Figure 6 As shown, the flame retardant and anti-odor fiber consists of a hollow hot-melt core 7 and an anti-odor layer 8 wrapped on the outer wall of the hot-melt core 7. The hot-melt core 7 is filled with a flame retardant filling liquid 6. The hot-melt core 7 can be melted at high temperature, so that the internal flame retardant filling liquid 6 leaks out and diffuses into the soft sponge layer 2 to achieve a good flame retardant effect. The anti-odor layer 8 is bamboo fiber, which has good antibacterial ability and prevents bacteria from breeding and producing odor. The hot-melt core 7 is polyester hot-melt fiber, which can be melted at high temperature to release the internal flame retardant filling liquid 6.
