Description

Technical Field

[0001] This utility model relates to the field of sponge product technology, and more specifically, it relates to a deformation-resistant cleaning sponge. Background Technology

[0002] Cleaning sponges are typically made of highly absorbent materials such as polyurethane, polyester, or nanomaterials. These materials possess excellent absorbency and softness, allowing them to quickly absorb moisture and penetrate stains, thereby removing them. The cleaning principle of a sponge is primarily based on its porous structure and physical adsorption. When the sponge absorbs water, its internal micropores open, creating a strong adsorption force that draws dirt to the sponge's surface and carries it away.

[0003] Because sponges are soft, they deform under pressure during use. A deformed sponge's water absorption and adsorption capacity decreases significantly, meaning its effectiveness in cleaning dishes drops considerably. It may fail to effectively remove grease and food residue, resulting in incomplete cleaning. The sponge's porous structure also makes it a breeding ground for microorganisms. Sponges used for extended periods, especially those not regularly washed and disinfected, may carry large amounts of bacteria, mold, and other microorganisms. A deformed sponge, due to its looser structure, is more likely to trap dirt and grime, increasing the risk of bacterial growth. Because of the reduced cleaning effectiveness of a deformed sponge, users may need to replace it more frequently, increasing resource consumption. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a deformation-resistant cleaning sponge with stronger deformation resistance.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A deformation-resistant cleaning sponge includes a lower sponge, a support plate, and an upper sponge, with the support plate placed between the lower and upper sponges. The support plate is made of EVA material.

[0007] The upper layer of sponge has several air holes, and its upper surface has an uneven, hilly structure.

[0008] The lower layer of sponge has several air holes, and the pore diameter of the air holes on the upper and lower layers of sponge is 0.8mm to 1cm. The lower layer of sponge, the support plate and the upper layer of sponge are connected by glue.

[0009] The present invention is further configured such that: in the hill-like structure, each protruding part has at least one hole at its top, and the opening direction of the hole forms an angle of 30° to 60° with the tangent of the surface of the protruding part.

[0010] The present invention is further configured such that the hill-like structure has a protrusion height of 5mm to 1cm.

[0011] The present invention is further configured such that the thickness ratio between the lower layer of sponge, the support plate and the upper layer of sponge is 5:1:5.

[0012] The present invention is further configured such that the opening direction of the air hole forms a 45° angle with the surface tangent of the protruding portion.

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

[0014] The upper sponge features an uneven, hilly surface, increasing the contact area and friction with the cleaning surface for more effective removal of stains and stubborn dirt. It is especially suitable for cleaning uneven or textured surfaces. Furthermore, the lower sponge is porous, allowing for rapid liquid absorption. The perforated design of the upper sponge layer (particularly the angle between the opening direction of the holes and the tangent of the raised surface at 30° to 60°) helps the liquid to be evenly distributed and quickly discharged during cleaning, preventing liquid stagnation and improving cleaning efficiency. Moreover, the support plate is made of EVA material, which has excellent support and elasticity, enhancing the overall structural strength of the cleaning sponge, preventing deformation or damage during use, extending its service life, and significantly improving cleaning effect, durability, and user comfort.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] Production Process: Lower Sponge 1: 1cm thick polyurethane foam with a 1cm pore size, offering excellent absorbency and softness. Support Board 2: 2mm thick EVA material, providing high elasticity and support. Upper Sponge 3: 1cm thick polyurethane foam with a 1.5mm pore size; its upper surface is molded to create an uneven, hilly structure 5 with a raised height of 5mm.

[0021] The lower layer sponge 1, support plate 2, and upper layer sponge 3 are then stacked in sequence and bonded together using environmentally friendly adhesive. The uneven structure of the upper layer sponge 3 is created using a thermoforming process. The top of the raised parts has holes with a diameter of 1mm, and the opening direction of the holes forms a 45° angle with the tangent of the surface of the raised parts. The overall thickness of the cleaning sponge is 22mm, and the edges are cut and trimmed to ensure a neat appearance.

[0022] like Figures 1 to 2 As shown,

[0023] It includes a lower layer of sponge 1, a support plate 2, and an upper layer of sponge 3. The thickness ratio between the lower layer of sponge 1, the support plate 2, and the upper layer of sponge 3 is 5:1:5, which maximizes the support function without affecting the performance.

[0024] The support plate 2 is placed between the lower layer sponge 1 and the upper layer sponge 3. The support plate 2 is made of EVA material, which has good support and elasticity, and can enhance the overall structural strength of the cleaning sponge, prevent the sponge from deforming or being damaged during use, and extend its service life.

[0025] The upper layer of sponge 3 has several air holes 4, and the upper surface of the upper layer of sponge 3 has an uneven hilly structure 5, which is used to enhance the cleaning effect and friction.

[0026] In the hill-like structure 5, each protrusion has at least one hole at its top, the opening direction of the hole forms an angle of 30° to 60° with the tangent of the surface of the protrusion, and the height of the protrusion is preferably 5 mm.

[0027] The lower layer of sponge 1 has several air holes 4. The diameter of the air holes 4 on the upper layer of sponge 3 and the lower layer of sponge 1 is 0.8mm to 1cm. The lower layer of sponge 1, the support plate 2 and the upper layer of sponge 3 are connected by glue, making production faster and more convenient.

[0028] The opening direction of the pore 4 is at a 45° angle to the surface tangent of the protruding part, which helps the liquid to be evenly distributed and quickly discharged during the cleaning process, avoids liquid retention, and improves cleaning efficiency.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
