Description

Technical Field

[0001] This utility model relates to the field of cleaning tool technology, specifically a multi-layer composite structure cleaning sponge. Background Technology

[0002] In the cleaning industry, cleaning sponges are widely used in homes, offices, and other cleaning environments as common cleaning tools. However, existing cleaning sponges have several problems. Some cleaning sponges only have a single physical cleaning function, and their cleaning effect is poor when faced with stubborn stains or cleaning scenarios containing bacteria and viruses. For example, ordinary nano-sponge erasers, while able to remove some dust and light stains, are difficult to thoroughly clean and disinfect grease in the kitchen or areas in the bathroom where bacteria thrive. Furthermore, the durability of existing cleaning sponges is generally insufficient. Ordinary nano-sponge erasers, for instance, have low toughness, tensile strength, and other physical properties, and poor elasticity and flexibility. During use, especially when squeezing out water, they are prone to breakage and damage, resulting in a short lifespan. Frequent replacement not only increases usage costs but also wastes resources. In addition, most cleaning sponges have limited antibacterial effects. If cleaning sponges are not cleaned and disinfected promptly after use, or if they are not thoroughly cleaned, they can easily breed a large number of bacteria and viruses, causing secondary pollution to the cleaning environment upon reuse and threatening human health.

[0003] Therefore, developing a cleaning sponge that integrates multiple functions and has good cleaning effect, durability and antibacterial properties is of great practical significance. Utility Model Content

[0004] To solve the above problems, the present invention adopts the following technical solution.

[0005] A multi-layer composite cleaning sponge includes a contact layer, an intermediate layer, and a bottom layer, which are sequentially laminated. The contact layer is a high-density sponge layer, the intermediate layer is an antibacterial nonwoven fabric layer containing nano-silver ions, and the bottom layer is a spunlace fabric reinforcement layer. The contact layer, intermediate layer, and bottom layer are connected by a hot melt adhesive web composite.

[0006] Preferably, the surface of the high-density sponge layer is provided with a matrix arrangement of friction drums.

[0007] Preferably, a slow-release disinfection bag is also provided between the middle layer and the bottom layer.

[0008] Preferably, the slow-release disinfection bag includes a water-permeable membrane and disinfection particles encapsulated within the water-permeable membrane.

[0009] Preferably, a cavity is provided between the middle layer and the bottom layer for placing the slow-release disinfection bag.

[0010] Preferably, the outer side of the bottom layer is provided with an inclined fixing strap.

[0011] Preferably, the fixing strap is an elastic band.

[0012] Preferably, a hand gripper is provided on the outer side of the bottom layer and on the inner side of the fixing strap. The hand gripper has a U-shaped structure, and anti-disengagement hooks are provided on the inner sides of the two gripping arms of the hand gripper. The anti-disengagement hooks are in contact with the sidewall of the contact layer.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention significantly enhances cleaning power by combining a high-density sponge in the contact layer with friction drums, effectively removing various stubborn stains. Compared to ordinary cleaning sponges, its cleaning efficiency is significantly improved. The intermediate layer utilizes nano-silver ions for continuous antibacterial action, and the slow-release disinfection bag releases disinfectant upon contact with water, achieving a dual function of antibacterial and disinfection. This effectively kills various bacteria, viruses, and fungi, providing users with a more hygienic and healthier cleaning environment and meeting the cleaning needs of different scenarios. The bottom spunlace fabric reinforcement layer effectively improves the tensile strength and durability of the cleaning sponge, making it less prone to damage under frequent use and significant external forces, extending its service life and reducing usage costs.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0024] like Figure 1-2 As shown in the figure, this embodiment provides a multi-layer composite cleaning sponge, which includes a contact layer 1, an intermediate layer 2 and a bottom layer 3 sequentially laminated together. The contact layer 1 is a high-density sponge layer, the intermediate layer 2 is an antibacterial non-woven fabric layer containing nano-silver ions, and the bottom layer 3 is a spunlace fabric reinforcement layer. The contact layer 1, the intermediate layer 2 and the bottom layer 3 are laminated and connected by a hot melt adhesive web film.

[0025] In this embodiment, the contact layer 1 is a high-density sponge layer, which has a high density and fine internal fibers, giving the sponge good flexibility and durability. During the cleaning process, the high-density sponge can effectively absorb dust, stains, and other impurities. Furthermore, the surface of the high-density sponge layer is provided with a matrix of arranged friction drums 11. These friction drums increase the friction with stains when wiping the surface of an object, more efficiently removing stubborn stains and improving the cleaning effect. Whether it's a smooth glass surface or rough tile grout, deep cleaning can be achieved through the action of the friction drums.

[0026] In this embodiment, the intermediate layer 2 is an antibacterial nonwoven fabric layer containing nano-silver ions. Nano-silver ions possess strong antibacterial capabilities, disrupting bacterial cell membrane structures and inhibiting bacterial growth and reproduction. During use and storage of the cleaning sponge, the nano-silver ions continuously exert their antibacterial effect, effectively inhibiting the growth of common bacteria such as Escherichia coli and Staphylococcus aureus on the cleaning sponge, preventing odors caused by bacterial growth, ensuring the hygiene of the cleaning sponge, and reducing the risk of secondary contamination. The antibacterial nonwoven fabric can be produced by uniformly mixing a solution containing nano-silver ions into the fiber raw material during the nonwoven fabric production process, followed by spinning, web forming, and other processes to create the antibacterial nonwoven fabric. Alternatively, the already produced nonwoven fabric can be post-treated by soaking, spraying, or other methods to attach nano-silver ions to the nonwoven fabric, followed by drying and curing steps to firmly bind the nano-silver ions within the nonwoven fabric.

[0027] In this embodiment, the bottom layer 3 is a spunlace fabric reinforcement layer. Spunlace fabric is made of various fibers entangled through a hydroentangling process, possessing excellent strength and stability. The presence of this layer greatly enhances the tensile strength and durability of the cleaning sponge, making it less prone to damage under repeated wiping, squeezing, and stretching. In practical use, even if the cleaning sponge is subjected to significant external force, the spunlace fabric reinforcement layer can ensure the integrity of the overall structure, extending the service life of the cleaning sponge.

[0028] In this embodiment, a slow-release disinfection bag 5 is provided between the middle layer 2 and the bottom layer 3, which further enhances the disinfection function of the cleaning sponge. The slow-release disinfection bag 5 includes a permeable membrane 51 and disinfection particles 52 encapsulated within the permeable membrane 51. When the cleaning sponge comes into contact with water, the water permeates through the permeable membrane 51 into the bag, causing the disinfection particles 52 to dissolve and release the disinfectant. For example, the disinfection particles 52 can be chlorine dioxide effervescent tablets. The chlorine dioxide released after dissolving has strong oxidizing properties and can thoroughly disinfect and sterilize the cleaned area, effectively killing bacteria, viruses, fungi, and other microorganisms, meeting the needs of scenarios with high cleanliness and hygiene requirements. When manufacturing the slow-release disinfection bag 5, the disinfection particles 52, such as chlorine dioxide effervescent tablets, are placed inside the permeable membrane 51, and then the permeable membrane 51 is sealed by heat sealing or ultrasonic welding to ensure that the disinfection particles 52 are well encapsulated and that the permeability of the permeable membrane 51 is not affected.

[0029] To better accommodate the slow-release disinfection bag 5, a receiving cavity 6 is provided between the middle layer 2 and the bottom layer 3. The design of the receiving cavity 6 not only fixes the position of the slow-release disinfection bag 5 and prevents it from moving around inside the cleaning sponge, but also protects the slow-release disinfection bag 5 from damage by external factors, ensuring the stable operation of the disinfection function.

[0030] In this embodiment, an inclined fixing strap 7 is provided on the outer side of the bottom layer 3, and the fixing strap 7 is an elastic strap. The design of the fixing strap 7 makes it easier for users to grip the cleaning sponge during use. The elasticity of the strap can adaptively adjust according to the user's grip strength and hand shape, providing a more comfortable and stable grip experience and reducing the possibility of the cleaning sponge slipping during use.

[0031] In addition, a hand-held clamp 4 is provided on the outer side of the bottom layer 3 and inside the fixing strap 7. The hand-held clamp 4 has a U-shaped structure. Anti-dislodgement hooks 41 are provided on the inner sides of the two clamping arms of the hand-held clamp 4, and the anti-dislodgement hooks 41 are in contact with the side wall of the contact layer 1. The combination of the hand-held clamp 4 and the anti-dislodgement hooks 41 further enhances the stability of the user's grip and prevents the cleaning sponge from falling out of the hand during use. Especially when cleaning areas that require greater force or special angles, it can effectively improve the convenience and safety of cleaning operations.

[0032] The working principle of the above technical solution is as follows:

[0033] When using this cleaning sponge, if the object being cleaned is general dust or light stains, it can be wiped directly with a dry cleaning sponge. The high-density sponge of the contact layer 1 and the friction drum 11 can effectively absorb and remove stains.

[0034] When the object being cleaned is stained with oil or harbors bacteria, the cleaning sponge is soaked. The moisture passes through the permeable membrane 51 into the slow-release disinfection bag 5, causing the disinfectant particles 52 to dissolve and release disinfectant substances. At this point, the cleaning sponge not only removes stains through physical wiping but also disinfects and sterilizes the cleaned area using the disinfectant substances. During the wiping process, the nano-silver ions in the intermediate layer 2 continue to exert their antibacterial effect, further ensuring the cleaning effectiveness.

[0035] When holding the cleaning sponge, the user can pass their hand through the retaining strap 7 and hold the hand grip 4. The elasticity of the retaining strap 7 and the design of the hand grip 4 allow the user to hold the cleaning sponge more securely, making it easier to apply force during cleaning, especially when cleaning high places or areas requiring greater friction, effectively preventing the cleaning sponge from slipping.

[0036] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
