Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning tool technology, and more specifically, to a shovel and grinder integrated blade. Background Technology
[0002] As a common cleaning tool, scrapers are widely used in many fields such as decoration, home furnishing, and automobiles to remove labels, paint, adhesive residue, dirt, and other substances from surfaces such as glass, tiles, and metal. Currently, traditional scrapers on the market have a very limited function, and their design usually focuses only on the sharpness of the blade. They achieve the scraping function by forming a line contact between the sharp edge and the surface of the object and using the principle of high pressure.
[0003] However, these traditional scrapers often prove ineffective when dealing with stubborn stains with strong adhesion, such as hardened silicone sealant, epoxy resin, paint spots, and hard limescale. Users need to scrape repeatedly and forcefully, which is not only inefficient and exhausting, but also prone to damaging the substrate surface due to excessive force or loss of angle control. Utility Model Content

[0005] The embodiments of this utility model can be implemented as follows: This utility model provides an integrated shovel and grinder, including a shovel body and a handle connected to the shovel body. The shovel body includes a shovel cutting surface and a grinding surface. The shovel cutting surface and the grinding surface are disposed at one end of the shovel body away from the handle or respectively disposed on both sides of the shovel body. The roughness of the grinding surface is greater than the roughness of the shovel cutting surface.
[0006] In an optional embodiment, the shovel surface and the grinding surface are respectively disposed on both sides of the shovel body, with all or part of the back side of the shovel body being the grinding surface and all or part of the front side of the shovel body being the shovel surface.

The grinding surface is adjacent to and connected to the back side of the shovel body and forms an obtuse angle with the back side of the shovel body. The grinding surface is inclined toward the front side of the shovel body.
[0008] In an optional embodiment, the shaving surface and the grinding surface are adjacent to each other and connected at an acute angle.
[0009] In an optional embodiment, a front end face is provided between the shovel surface and the grinding surface, and the front end face is connected to the shovel surface and the grinding surface at an obtuse angle.

[0024] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0025] The following describes in detail the overall structure, working principle, and technical effects of the integrated shovel and grinder provided by this utility model through embodiments and in conjunction with the accompanying drawings.
[0026] Please refer to Figures 1-3 The integrated scraper and grinder 100 provided by this utility model can be applied to various occasions where surface attachments need to be cleaned, and is especially suitable for solving the problem of stubborn stains with high adhesion that are difficult to handle by traditional scraper tools.
[0027] This integrated scraping and grinding tool 100 includes a scraper body 10 and a handle 30 connected to the scraper body 10. The scraper body 10 includes a scraping surface 11 and a grinding surface 12. The scraping surface 11 and the grinding surface 12 are located at one end of the scraper body 10 away from the handle 30 or respectively on both sides of the scraper body 10. The roughness of the grinding surface 12 is greater than that of the scraping surface 11. It can be understood that the scraping surface 11 and the grinding surface 12 being located at one end of the scraper body 10 away from the handle 30 means that the scraping surface 11 and the grinding surface 12 are located on one side edge of the scraper body 10. The scraping surface 11 and the grinding surface 12 being respectively located on both sides of the scraper body 10 means that the scraping surface 11 and the grinding surface 12 are respectively located on two opposite surfaces of the scraper body 10. Figure 1 The first-view perspective of the integrated grinding tool shown is from the front (top surface). Figure 2 The second perspective of the integrated grinding tool shown is the back side (lower surface).
[0028] Specifically, in this embodiment, the shovel surface 11 and the grinding surface 12 are disposed at the end of the shovel body 10 away from the handle 30. The shovel surface 11 is adjacent to and connected to the front surface of the shovel body 10 and forms an obtuse angle with the front surface of the shovel body 10, and the shovel surface 11 is inclined towards the back surface of the shovel body 10. The grinding surface 12 is adjacent to and connected to the back surface of the shovel body 10 and forms an obtuse angle with the back surface of the shovel body 10, and the grinding surface 12 is inclined towards the front surface of the shovel body 10. It can be understood that by setting chamfered structures on the edges of the upper and lower surfaces of the end of the shovel body 10 away from the handle 30, and setting the chamfered planes as the shovel surface 11 and the grinding surface 12 respectively, the shovel surface 11 forms an obtuse angle with the upper surface (front surface) of the shovel body 10, and the grinding surface 12 forms an obtuse angle with the lower surface (back surface) of the shovel body 10. In use, grinding is achieved by making the shovel body 10 at a certain angle to the surface to be cleaned, so that the grinding surface 12 contacts the surface to be cleaned, or by making the scraping surface 11 away from the edge of the shovel body 10 contact the surface to be cleaned to achieve scraping.
[0029] In another embodiment of this utility model, the scraping surface 11 and the grinding surface 12 are respectively disposed on both sides of the shovel body 10. All or part of the back surface of the shovel body 10 is the grinding surface 12. All or part of the front surface of the shovel body 10 is the scraping surface 11. It can be understood that all or part of the upper surface (front) of the shovel body 10 is set as the scraping surface 11, and all or part of the lower surface (back) of the shovel body 10 is set as the scraping surface 11. That is, the scraping surface 11 and the grinding surface 12 are arranged in parallel. In use, grinding is achieved by moving the shovel body 10 and bringing its lower surface (back) into contact with the surface to be cleaned; or by flipping the shovel body 10 over and bringing the edge of the upper surface (front) away from the handle 30 into contact with the surface to be cleaned to achieve scraping. It should be noted that when the shaving surface 11 is located on the front side of the shovel body 10, the shaving surface 11 is located at the end of the front side of the shovel body 10 away from the handle 30, so that the shaving surface 11 forms an edge at the part of the shovel body 10 away from the handle 30, which facilitates shaving. As for the grinding surface 12, this utility model does not make any limitations.
[0030] In this embodiment, the grinding surface 12 is a rough surface, and the scraping surface 11 is a smooth surface. By setting opposite smooth scraping surfaces 11 and rough grinding surfaces 12, and making them both inclined wedge-shaped structures, the shovel body 10 can simultaneously possess two different functional modes: scraping and grinding. The user can switch the functions of the shovel body 10 simply by rotating the handle 30 to flip the shovel body 10, thereby expanding the application scenarios of a single tool and improving the cleaning effect.
[0031] Specifically, in this embodiment, in the grinding mode, the grinding surface 12 is placed downwards and in contact with the surface of the substrate to be cleaned. The scraper body 10 is moved so that the grinding surface 12 rubs against the substrate surface. Through the scraping action of the particles, the highly adhesive stains on the substrate surface are gradually ground up and peeled off. In the scraping mode, the edge of the scraping surface 11 is placed in contact with the surface to be cleaned. The cutting angle of the scraping surface 11 is adjusted by the handle 30, and the scraping surface 11 is pushed horizontally along the extension direction of the scraper body 10. The small contact area of the edge of the scraping surface 11 generates greater pressure, thereby cutting into the stain and scraping it up. It can be understood that the grinding mode is suitable for handling stubborn stains with small areas, high hardness, and high adhesion. The scraping mode is suitable for handling stains with large areas and weak adhesion. Users can choose different working modes according to actual needs.
[0032] The grinding surface 12 is used to contact the surface to be cleaned. Moving the grinding surface 12 and rubbing against the surface cleans it. The scraping surface 11 is used so that its edge contacts the surface to be cleaned. Moving the scraper body 10 cuts into the surface dirt, and the dirt cut off is moved onto the scraper body 10 through the beveled scraping surface 11, thereby removing the dirt. The surface of the scraper body 10 can collect and remove the cleaned dirt. It can be understood that the grinding surface 12 has surface contact with the surface to be cleaned, while the scraping surface 11 has line contact with the surface to be cleaned. The grinding surface 12, being a rough surface, provides more stable operation and is less prone to slippage.
[0033] Specifically, the abrasive surface 12 is a roughened surface treated with sandblasting. It can be understood that sandblasting creates a rough structure on the surface of the abrasive surface 12 consisting of uniform, hard, and sharp microscopic protrusions. When the abrasive surface 12 rubs against stains, these micro-protrusions act like countless tiny cutting edges, capable of scraping and breaking up stubborn stains with high adhesion.
[0034] Specifically, the surface roughness Ra of the abrasive surface 12 ranges from 3.2 μm to 25 μm. Understandably, the higher the Ra value, the rougher the surface. By setting the lower limit of Ra to 3.2 μm, excessively fine particles in the abrasive surface 12 are prevented from causing frictional failure. If the roughness is below this value (e.g., Ra = 1.6 μm or 0.8 μm), the surface is too smooth, resulting in extremely weak abrasive power and ineffective removal of highly adhesive stains. By setting the upper limit of Ra to 25 μm, excessively coarse particles in the abrasive surface 12 are prevented from damaging the substrate. If the roughness is above this value (e.g., Ra = 50 μm), the surface becomes as sharp as a coarse file. While this provides strong polishing power, it is highly likely to cause irreversible scratches to most substrates (such as ceramic glazes, glass, and stainless steel countertops).
[0035] Preferably, the surface roughness Ra of the abrasive surface 12 ranges from 6.3 μm to 12.5 μm. This satisfies the requirements for cleaning highly adhered stains while preventing excessive roughness from scratching the surface of the substrate to be cleaned.
[0036] In this embodiment, a front end face 13 is provided between the shovel surface 11 and the grinding surface 12. The front end face 13 is connected to the shovel surface 11 and the grinding surface 12 at an obtuse angle. It can be understood that by providing the front end face 13, the end of the shovel body 10 away from the handle 30 is prevented from being sharp. On the one hand, this reduces the risk of injury to the operator, and on the other hand, it disperses the stress of shoveling by the shovel surface 11, making the end of the shovel surface 11 less prone to breakage during the shoveling process.
[0037] Of course, in another embodiment of this utility model, the shovel surface 11 and the grinding surface 12 can be arranged to be adjacent and connected at an acute angle. While ensuring the strength of the shovel body 10, the sharpness of the end of the shovel body 10 is maximized and the cutting resistance is reduced.
[0038] Furthermore, the included angle between the scraping surface 11 and the grinding surface 12 is 70°-80°. It is understood that in this embodiment, both the scraping surface 11 and the grinding surface 12 are set at an angle to the surface of the scraper body 10. By setting the included angle between the scraping surface 11 and the grinding surface 12 to 70°-80°, it is ensured that the end of the scraping surface 11 can form a sufficiently sharp wedge angle. Compared to a 90° right-angle cutting edge, the 70°-80° angle makes it easier for the cutting edge to cut into the bottom of the stain, significantly reducing the initial resistance and pushing resistance of scraping, making the operation more labor-saving and efficient. This ensures the effective contact area of the grinding mode. The effective contact area refers to the size of the effective contact area participating in grinding when the grinding surface 12 is placed face down on a flat surface. The 70-80° angle allows the grinding surface 12 to form a wide and flat grinding area, making the pressure dispersion less likely to scratch the substrate, while also being able to handle a larger area of stains.
[0039] Furthermore, in this embodiment, the area of the grinding surface 12 is larger than the area of the scraping surface 11. It is understood that the grinding surface 12 is the surface in complete contact with the surface to be cleaned. The scraping surface 11 only contacts the surface to be cleaned at its end. By providing a larger grinding surface 12, a larger area can be covered at once, improving cleaning efficiency. Specifically, in this embodiment, the angle between the grinding surface 12 and the lower surface of the scraper body 10 is greater than the angle between the scraping surface 11 and the upper surface of the scraper body 10, so that the area of the grinding surface 12 is larger than the area of the scraping surface 11.
[0040] Furthermore, the shovel body 10 and the handle 30 are set at an angle of 165°-175°. Understandably, when the user naturally holds the handle 30, this 165°-175° angle allows the shovel body 10 to conform to the surface to be cleaned in the most natural and effortless manner. The user's wrist does not need to be excessively bent or maintain an unnatural, stiff angle to perform pushing or polishing actions, greatly reducing wrist strain and fatigue caused by prolonged operation.
[0041] In this embodiment, a connecting portion 20 is also provided between the shovel body 10 and the handle 30. The connecting portion 20 is set at an angle to both the shovel body 10 and the handle 30. One end of the connecting portion 20 that connects to the handle 30 is bent relative to the end of the handle 30 facing the grinding surface 12. One end of the shovel body 10 that connects to the connecting portion 20 is bent relative to the end of the connecting portion 20 facing the scraping surface 11. It can be understood that by providing the connecting portion 20 between the shovel body 10 and the handle 30, the integrated shovel and grinder 100 forms a "Z"-shaped structure or a double-bent structure. By bending the connecting portion 20 to the handle 30, the position of the handle 30 can be raised, allowing the user's knuckles and palms to be away from the work surface during operation, avoiding friction and collision between the joints and the table, wall, etc., during grinding or scraping, thus improving the comfort and safety of operation. By bending the shovel body 10 and the connecting part 20, the spatial posture of the shovel body 10 relative to the handle 30 can be precisely adjusted, ensuring that when the user naturally holds the handle 30, whether using the shovel surface 11 or the grinding surface 12, the shovel body 10 can contact the working surface at the most ideal angle without twisting the wrist.
[0042] In this embodiment, a through hole 31 is provided at the end of the handle 30 away from the shovel body 10. It can be understood that by providing the through hole 31, it is convenient for the user to suspend the integrated shovel and sharpening blade 100 with a rope or hook, making it convenient for tool storage.
[0043] Furthermore, the handle 30 is provided with anti-slip texture (not shown). By providing anti-slip texture, the user is effectively prevented from slipping while using the integrated sharpening and shoveling tool 100, thus improving the user's handling experience.
[0044] In this embodiment, the handle 30 and the shovel body 10 are integrally formed. Specifically, in this embodiment, both the handle 30 and the shovel body 10 are made of metal and are manufactured by precision casting or forging integral forming process to improve the durability of the integrated shovel and grinding blade 100.
[0045] Of course, in other embodiments, the handle 30 and the shovel body 10 can also adopt a detachable connection structure. For example, the shovel body 10 can be detachably connected to the handle 30 by means of bolts or other structures. By providing a detachable connection structure between the handle 30 and the shovel body 10, the shovel body 10 and the handle 30 can be interchanged, making it convenient to replace the shovel body 10 and the handle 30.
[0046] The beneficial effects of the integrated grinding and shoveling tool 100 provided in this embodiment of the present invention include: The integrated scraping and grinding tool 100 provided by this utility model includes a scraper body 10 and a handle 30 connected to the scraper body 10. The scraper body 10 includes a scraping surface 11 and a grinding surface 12. The scraping surface 11 and the grinding surface 12 are disposed at one end of the scraper body 10 away from the handle 30 or respectively disposed on both sides of the scraper body 10. The roughness of the grinding surface 12 is greater than that of the scraping surface 11. By separately setting the scraping surface 11 and the grinding surface 12 on the same scraper body 10, the scraping and grinding functions are integrated, allowing users to continuously complete the two processes of scraping and polishing without changing tools, greatly improving operating efficiency and convenience. This utility model can realize the integration of scraping and grinding functions, improve cleaning efficiency, and protect the substrate.
[0047] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
