A cleaning sponge

Abstract

A cleaning sponge includes a brushed outer layer, a hooked inner layer, a central sponge, and an outer ring sponge layer. The brushed outer layer is used as the part with strong friction, replacing the existing dual-purpose cleaning sponge. The hooked inner layer is fixed to the back of the brushed outer layer. A brushed connecting layer is fixed to one side of both the central sponge and the outer ring sponge layer. The brushed connecting layer is bonded to the hooked inner layer to form a detachable structure. The center of the portion of the outer ring sponge layer with the brushed connecting layer has a central groove that can accommodate the central sponge. Both opposite ends of the outer ring sponge layer have extended portions that protrude outwards. The tips of the extended portions are pointed, making it easy to reach into crevices or corners for cleaning. Two sets of gripping grooves are formed on the side of the brushed outer layer away from the brushed inner layer. When using, fingers are inserted into the gripping grooves, which avoids friction and abrasion of the fingers during cleaning, rather than directly gripping the entire cleaning sponge.

Description

Technical Field

[0001] This utility model relates to cleaning products, specifically a cleaning sponge. Background Technology

[0002] Cleaning sponges, also known as super-strong stain-removing foams, magic sponges, or nano sponges, are high-density physical cleaning tools made from melamine resin. They rely on their internal nanocapillary structure to absorb stains, removing stubborn dirt such as tea stains and grease without detergent. Suitable for smooth surfaces such as ceramics, glass, and stainless steel, they are environmentally friendly, antibacterial, and do not damage the materials. With expanding market demand, the application of cleaning sponges has extended from home cleaning to kitchens, car interiors, and other areas.

[0003] Existing cleaning sponges are mostly dual-purpose, with a strong abrasion side and a weak abrasion side to wipe different cleaning needs. However, as usage demands increase, the sponge's single-purpose design becomes insufficient. For example, some sponges can only be used by hand. While there are sponges with handles on the market, they are not dual-purpose. This variety of products forces consumers to purchase different sponges for different needs, increasing the storage of cleaning products and storage requirements. For manufacturers, this necessitates more molds and production, leading to higher costs. Therefore, an improved technology is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the above-mentioned issues and provide a cleaning sponge.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a cleaning sponge, comprising a brushed outer layer, a hooked inner layer, a central sponge, and an outer ring sponge layer. The brushed outer layer is used as the part with strong friction, replacing the existing dual-purpose cleaning sponge. The hooked inner layer is fixed to the back of the brushed outer layer by heat pressing or stitching. A brushed connecting layer is fixed to one side of both the central sponge and the outer ring sponge layer, fixed by heat pressing or stitching. The brushed connecting layer and the hooked inner layer are bonded together to form a detachable structure. A central groove for accommodating the central sponge is formed at the center of one side of the outer ring sponge layer. Both opposite ends of the outer ring sponge layer have extended portions that are integrally formed with the outer ring sponge layer. The top of the extended portion is a pointed tip, which is easy to reach into crevices or corners for cleaning. Two sets of gripping grooves are formed on the side of the brushed outer layer away from the brushed inner layer. The gripping grooves can directly penetrate the brushed outer layer. When using, fingers are inserted into the gripping grooves, which avoids friction and abrasion of the fingers during cleaning, rather than directly gripping the entire cleaning sponge.

[0006] Furthermore, each set of grip grooves includes two arc-shaped grooves, with the virtual center of the arc-shaped groove located between the two arc-shaped grooves; the arc-shaped grooves are located at both ends of the brushed outer layer.

[0007] Furthermore, the central groove and the central sponge are matched in circular or elliptical shapes to facilitate fitting and docking.

[0008] Furthermore, the virtual angle at the tip of the extended portion is an acute angle, and the extended portion extends away from the outer abrasive layer, making it easy to reach into the nooks and crannies of the object being cleaned.

[0009] Furthermore, the brushed connecting layer between the central sponge and the outer ring sponge layer is made of different colors, making it easy to identify with the naked eye which color part is bonded to which sponge.

[0010] Advantages of this utility model:

[0011] 1. The detachable structure makes it easy to change the usage of the cleaning sponge, which can be used to clean different cleaning needs, increase the number of uses, reduce the variety of products, unify the appearance, save production resources, reduce the amount of consumer purchases, reduce procurement costs and storage expenses.

[0012] 2. When cleaning sticky oil stains, the oil stains tend to stick to the outer sponge layer and are difficult to clean, but the inner central sponge is intact. In this case, you can peel off the outer and middle sponge layers and continue to use this product to extend its service life. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] Combined with appendix Figures 1-3 A cleaning sponge includes a brushed outer layer, a hooked inner layer, a central sponge, and an outer ring sponge layer. The brushed outer layer is used as the part with strong friction, replacing the existing dual-purpose cleaning sponge. The hooked inner layer is fixed to the back of the brushed outer layer by heat pressing or stitching. A brushed connecting layer is fixed to one side of both the central sponge and the outer ring sponge layer by heat pressing or stitching. The brushed connecting layer and the hooked inner layer are bonded together to form a detachable structure. The center of the portion of the outer ring sponge layer with the brushed connecting layer has a central groove that can accommodate the central sponge. Both opposite ends of the outer ring sponge layer have extended portions that protrude outwards, which can be integrally formed with the outer ring sponge layer. The top of the extended portion is a pointed tip, which is easy to reach into crevices or corners for cleaning. Two sets of gripping grooves are formed on the side of the brushed outer layer away from the brushed inner layer. The central groove and the central sponge are matched with each other in a circular or elliptical shape for easy mating. The grip groove extends directly through the abrasive outer layer. When using it, you can insert your fingers into the grip groove. This avoids rubbing your fingers with the cleaning agent during the cleaning process, rather than holding the entire cleaning sponge directly.

[0021] As one embodiment of this utility model, each set of gripping grooves includes two arc-shaped grooves, with the virtual center of the arc-shaped groove located between the two arc-shaped grooves; the arc-shaped grooves are located at both ends of the roughened outer layer.

[0022] As one embodiment of this utility model, the virtual included angle of the tip of the extended portion is an acute angle, and the extended portion extends in a direction close to the outer layer of the abrasive, making it easy to reach into the nooks and crannies of the object being cleaned.

[0023] As one embodiment of this utility model, the brushed connecting layer of the central sponge and the outer ring sponge layer is made of different colors, which makes it easy to identify with the naked eye which color part is bonded to which sponge.

[0024] In specific implementation of this utility model: the central sponge and outer ring sponge layer of this utility model product are engaged with the brushed connecting layer through the hook surface inner layer to form a detachable structure to meet different usage needs;

[0025] For example, if it's used for wiping high places, use the extended section as the top and bottom. Wrap the brushed outer layer around the clothes hanger (almost every household has a clothes hanger, so you can use this directly). Peel off a portion of the outer foam from the edge, and attach the brushed outer layer to the hanger. When the inner hook layer overlaps with the brushed outer layer, they will adhere to each other. (See reference.) Figure 4The curled and extended portion forms a top, allowing the product to be stably positioned at one end of the handle. The handle can then be held to clean high places or inserted into bottles and jars for cleaning, thus achieving a multi-functional purpose.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
