Description

Technical Field

[0001] This utility model relates to the field of cleaning tool technology, specifically to a replaceable core cleaning sponge. Background Technology

[0002] Cleaning sponges are commonly used cleaning tools in daily life and industrial cleaning. However, after a period of use, existing cleaning sponges lose their cleaning effectiveness due to absorbing large amounts of dirt and breeding bacteria, requiring complete replacement, resulting in resource waste and increased usage costs. Furthermore, traditional cleaning sponges suffer from structural design flaws, such as unstable connections between the sponge and mounting components, making them prone to detaching during cleaning, and inconvenient sponge replacement, all of which affect cleaning efficiency and user experience. Therefore, there is an urgent need for a cleaning sponge with a replaceable core and a stable structure. Utility Model Content

[0003] To solve the above problems, the present invention adopts the following technical solution.

[0004] A replaceable core cleaning sponge includes a housing, a cover plate detachably provided on the top of the housing, a bottom plate detachably provided on the bottom of the housing, an opening in the middle of the bottom plate, and a plurality of cleaning units laid flat inside the housing. Each cleaning unit includes a plurality of longitudinally arranged cleaning modules, and each cleaning module includes a fixing block with a cleaning sponge on the bottom surface of the fixing block.

[0005] Preferably, the fixing block has an internal cavity and an opening at its top.

[0006] Preferably, the connection area between the cleaning sponge and the bottom surface of the fixing block is included within the area of ​​the vertical projection of the receiving cavity.

[0007] Preferably, the bottommost cleaning sponges extend out of the opening, and the bottom of the outer edge of the bottommost fixing block contacts the upper surface of the base plate.

[0008] Preferably, guide strips are provided on the front and rear sides of the fixing block, and sliding grooves are provided inside the housing corresponding to each guide strip.

[0009] Preferably, the bottom surface of the cover plate is provided with a pressure plate, and the bottom surface of the pressure plate is in contact with the top surface of the uppermost fixing block.

[0010] Preferably, a sealing ring is provided on the outer side of the bottom surface of the fixing block.

[0011] Preferably, the outer wall of the housing is provided with several drainage and ventilation holes.

[0012] Preferably, the cover plate is detachably provided with a handle on its outer side.

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

[0014] This invention features a detachable cover plate on the top of the housing and a detachable base plate on the bottom. When the cleaning sponge on a cleaning module needs to be replaced after a period of use, simply open the cover plate and the base plate to easily remove the entire cleaning module from the bottom. Then, insert the new cleaning module from the top and squeeze it out from the bottom, achieving rapid replacement of the cleaning sponge core. The operation is simple and convenient, improving the efficiency of cleaning sponge usage.

[0015] The guide strips on the front and rear sides of the fixing block of this utility model cooperate with the sliding groove inside the housing, making the installation of the cleaning module in the housing more stable and less prone to shaking; at the same time, the sealing ring set on the outer side of the bottom surface of the fixing block can not only prevent liquid from seeping into the gap between the fixing block and the housing during the cleaning process, but also increase the friction between the fixing block and the housing, making the installation of the cleaning module more secure.

[0016] Because the cleaning module can be replaced separately, this invention avoids the situation where the entire cleaning sponge is discarded due to dirt, thus reducing resource waste, extending the service life of the cleaning sponge, and lowering the cost of use. Attached Figure Description
