Description

Technical Field

[0001] This utility model relates to the field of whiteboard eraser manufacturing technology, and in particular to a whiteboard eraser with double-sided cleaning surfaces. Background Technology

[0002] Currently, whiteboards, due to their dust-free writing properties when using water-based pens, are gradually replacing traditional blackboards and are widely used in most schools. However, whiteboard erasers on the market consist of a panel and a fixed felt. After prolonged use, the felt absorbs a large amount of pen ink, becomes dirty, and is difficult to remove. Since the felt is fixed to the panel and cannot be removed, it must be discarded entirely when dirty, resulting in high costs. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model proposes a whiteboard eraser with a double-sided cleaning surface.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a whiteboard eraser with double-sided cleaning surfaces, comprising a housing and a cleaning component disposed on the housing, the housing being composed of a base plate and a surrounding wall surrounding the periphery of the base plate, forming a receiving cavity between the base plate and the surrounding wall, the cleaning component comprising a mounting plate, a first cleaning surface disposed on the upper surface of the mounting plate and a second cleaning surface disposed on the lower surface of the mounting plate, the cleaning component being detachably mounted in the receiving cavity via the mounting plate.

[0005] In a further improvement, the cavity is equipped with a magnetic attraction, and the upper and lower surfaces of the mounting plate are respectively provided with metal sheets or magnetic materials that can be magnetically attracted.

[0006] In a further improvement, the cavity is equipped with a magnetic attraction, and the mounting plate is made of a metal or magnetic material that can be magnetically attracted.

[0007] As a further improvement, the walls of the housing are inclined, making the housing as a whole wedge-shaped structure.

[0008] As a further improvement, the inclination angle of the shell enclosure is 8° to 20°.

[0009] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: By setting a double-sided cleaning structure, not only can the practicality of the whiteboard eraser be improved, but its service life can also be extended, and the replacement frequency can be reduced, thereby achieving energy saving and environmental protection. When in use, the first or second cleaning surface is embedded in the receiving cavity, while the other cleaning surface is exposed. When it is necessary to switch cleaning surfaces, it is only necessary to remove the cleaning component from the housing and flip it over for installation. In addition, the design structure is simple and easy to operate, and it is suitable for various whiteboard usage scenarios. Furthermore, by setting a magnetic attraction and the cooperation of metal sheets or magnetic materials, the installation and disassembly of the cleaning component is more convenient and quick, and users can complete the replacement without the aid of tools, improving the convenience of use. Furthermore, the design of the inclined angle of the housing wall makes the whiteboard eraser fit the palm more when held, improving the comfort of operation. Attached Figure Description

[0014] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0015] refer to Figure 1-2 This embodiment provides a whiteboard eraser with double-sided cleaning surfaces, including a housing 1 and a cleaning component 2 disposed on the housing 1. The housing 1 consists of a base plate 11 and a surrounding wall 12 surrounding the periphery of the base plate 11, forming a receiving cavity between the base plate 11 and the surrounding wall 12. The cleaning component 2 includes a mounting plate 21, a first cleaning surface 22 disposed on the upper surface of the mounting plate 21, and a second cleaning surface 23 disposed on the lower surface of the mounting plate 21. The cleaning component 2 is detachably installed in the receiving cavity via the mounting plate 21. Specifically, a magnet 3 is provided in the receiving cavity, and the magnet 3 is disposed along the inner wall of the receiving cavity. The mounting plate 21 is made of a metal material or magnetic material that can be attracted by the magnet 3. In use, the first cleaning surface 22 or the second cleaning surface 23 is embedded in the receiving cavity, while the other cleaning surface is exposed. When it is necessary to switch cleaning surfaces, the cleaning component 2 can simply be removed from the housing 1 and flipped over for installation.

[0016] In practical applications, the mounting plate 21 can also be made of non-metallic or non-magnetic materials, and the upper and lower surfaces of the mounting plate 21 are respectively provided with metal sheets or magnetic materials that can be attracted by magnets 3, thereby achieving a stable installation of the cleaning component 2.

[0017] In practical applications, the mounting plate 21 and the receiving cavity can also adopt common connection structures such as snap-fit ​​connection structure or interference fit structure to achieve quick disassembly and assembly and stable connection of cleaning component 2.

[0018] In this embodiment, the enclosure wall 12 of the housing 1 is inclined, so that the housing 1 as a whole has a wedge-shaped structure. The inclination angle α of the enclosure wall 12 of the housing 1 is 8° to 20°, preferably 15°. This inclination angle design not only makes it easier for the user to hold the whiteboard eraser to fit the palm of the hand and improve the comfort of operation, but also enhances the force transmission efficiency of the whiteboard eraser during the wiping process, making cleaning more efficient.

[0019] In actual operation, the first cleaning surface 22 and the second cleaning surface 23 can be made of the same material or different materials to suit different cleaning needs.

[0020] This utility model, by setting a double-sided cleaning structure, not only improves the practicality of the whiteboard eraser but also extends its service life and reduces the frequency of replacement, thereby achieving energy-saving and environmentally friendly effects.

[0021] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
