Description

Technical Field

[0001] This utility model relates to the field of cleaning tool technology, specifically to an inner wall cleaning tool adapted to complex curved surfaces. Background Technology

[0002] In the field of powder processing (such as starch), tanks are widely used as common containers for processing and storing powders. However, cleaning the inner walls of these tanks has always been a challenge, especially for tanks with complex curved surfaces. Most existing cleaning tools have a simple structure and are difficult to adapt to the inner walls of tanks with different diameters and complex curved surfaces. For example, ordinary flat cleaning brushes cannot closely conform to curved surfaces, leaving many dead corners during cleaning, making it difficult to thoroughly remove powder and other residues, affecting the subsequent use of the tank and product quality. Existing cleaning tools, such as the one disclosed in Chinese Patent Publication No. CN218637266U, which describes a cleaning tool suitable for mixing tanks, lack a flexible adjustment mechanism when dealing with tanks of different depths, making operation inconvenient and cleaning efficiency low. Therefore, developing a cleaning tool that can effectively adapt to the inner walls of tanks with complex curved surfaces and improve cleaning quality and efficiency is of significant practical importance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an inner wall cleaning tool that is adapted to complex curved surfaces.

[0004] The technical solution adopted in this utility model is as follows: An interior wall cleaning tool adaptable to complex curved surfaces, comprising the following components: The hand-held part is designed in the shape of a long handle; The scraper part is installed at the end of the handheld part. The middle connection between the handheld part and the scraper part is the support point. The scraper part is made of rubber and has a wedge-shaped cross-section with a narrow end face, a wide end face, and a cleaning arc surface connecting the narrow end face and the wide end face. It is used to clean the powder residue on the inner wall of the can with different diameters by using the cleaning arc surface to contact the inner wall of the can. The diagonal bracing section includes inclined rods, which are respectively connected to both ends of the scraper section; The sleeve part is arranged in a ring shape. It is located at the intersection of the diagonal bars and is sleeved on the surface of the handle part, and slides up and down along the handle part.

[0005] This technical solution utilizes the flexibility and wedge-shaped structure of the scraper section, combined with the lever principle of the inclined support section, to allow the scraper section to deform according to the curvature of the inner wall of the can, cleaning curved surfaces that conform to curved surfaces of different diameters. The inclined support section and the support point form a stable triangular structure. When the sleeve section slides, the angle of the inclined support section changes, causing the scraper section to change from a triangle to a fan shape, increasing the degree of curvature and enhancing the fit, thus achieving efficient cleaning. Specifically, the deformable rubber scraper section, in conjunction with the cleaning curved surface and the inclined support section, can closely fit the inner wall of the can with different curvatures, effectively scraping away powder residue. The sleeve section can slide along the handle section, adjusting its position according to the depth of the can to meet the cleaning needs of cans of different sizes. The long-handled handle section facilitates operation, reduces physical exertion during cleaning, and improves cleaning efficiency. This technical solution, by providing a specifically structured handle section, scraper section, inclined support section, and sleeve section, allows the cleaning tool to adjust the shape of the scraper section according to the curvature of the inner wall of the can, enhancing the fit with the inner wall, thereby effectively cleaning powder residue adhering to the inner wall.

[0006] In addition, the inner wall cleaning tool adapted to complex curved surfaces proposed above according to this utility model may also have the following additional technical features: According to one embodiment of the present invention, the two diagonal rods of the diagonal brace are symmetrically arranged at both ends of the scraper part, and the two diagonal rods intersect at the sleeve part to form a stable support structure.

[0007] In this technical solution, during the cleaning process, the scraper is subjected to the reaction force of the inner wall of the tank. The reaction force is transmitted to the sleeve part through the diagonal bar, and then dispersed by the connection between the sleeve part and the hand handle, forming a force balance and transmission path.

[0008] According to one embodiment of the present invention, the sleeve is provided with a locking inner sleeve. By rotating the locking inner sleeve, the sleeve can be locked at any height of the handle to adapt to the cleaning needs of tanks of different depths.

[0009] In this technical solution, when the inner sleeve is rotated and locked, the contact pressure between the inner sleeve and the handle and the sleeve part is changed. By utilizing the principle of friction, sufficient resistance is generated between the sleeve part and the handle part, thereby locking the sleeve part at any height of the handle part to adapt to the cleaning of tanks of different depths.

[0010] According to one embodiment of the present invention, the scraper portion deforms under the action of the inclined support portion, and the shape of the combination of the scraper portion and the inclined support portion changes from a triangle to a fan shape.

[0011] This technical solution applies force to the scraper section through the inclined support section, and utilizes the elasticity of the rubber material of the scraper section to redistribute the internal stress of the scraper section, thereby changing its shape and realizing the transformation from a triangle to a fan shape to adapt to different curvatures of the inner wall of the tank.

[0012] According to one embodiment of the present invention, when the scraper part is fan-shaped, it is curved in an arc shape on the basis of its own cleaning arc surface, so as to fit the inner wall of the tank with a complex curved surface.

[0013] In this technical solution, the fan-shaped and curved structure better fits the complex curved inner wall of the tank, reducing cleaning dead corners and improving cleaning quality.

[0014] According to one embodiment of the present invention, the support point is located at the middle connection position between the scraper part and the handheld part, in order to improve the strength of the arc-shaped scraper part.

[0015] In this technical solution, the handheld part extends forward along the sleeve part, which can reasonably distribute the squeezing force on the scraper part, optimize the force transmission path, make the internal stress evenly distributed, and thus improve the strength of the arc-shaped scraper part.

[0016] According to one embodiment of the present invention, the surface of the handheld part is provided with an anti-slip texture.

[0017] In this technical solution, the anti-slip texture is used to increase the friction between the handgrip and the user's hand, ensuring that the user can firmly grip the tool during operation.

[0018] According to one embodiment of the present invention, the included angle between the inclined rod of the inclined support and the hand-held part is in the range of 30°~60°.

[0019] In this technical solution, when the included angle is within the range of 30° - 60°, the inclined bar can better distribute the reaction force from the inner wall of the tank to the scraper part, converting the vertical force into a component force along the inclined bar and the handle part, reducing excessive local stress and avoiding structural damage.

[0020] Compared with the prior art, this utility model has the following advantages: (1) The scraper section is wedge-shaped, and the rubber material makes it flexible. Under the action of the diagonal support, it can change from a triangle to a fan shape and the whole is curved. This allows the cleaning arc surface of the scraper to fit closely to the inner wall of the tank with different curvatures, effectively reducing cleaning dead corners and improving cleaning quality.

[0021] (2) The scraper part and the inclined support part can flexibly deform according to the curvature of the inner wall of the tank, switching between the triangular and fan-shaped states; whether facing tanks of different diameters or complex curved surfaces, it can achieve good fit through deformation, effectively scrape off powder residues, and meet diverse cleaning needs.

The scraper part 3 is made of rubber and has a wedge-shaped cross section with a narrow end face 32, a wide end face 33, and a cleaning arc surface 31 connecting the narrow end face 32 and the wide end face 33. It is used to clean the powder residue on the inner wall of the can with different diameters by contacting the cleaning arc surface 31. The diagonal bracing part 4 includes an inclined rod, which is connected to both ends of the scraper part 3 respectively; The sleeve part 5 is arranged in a ring shape. It is located at the intersection of the diagonal bars and is sleeved on the surface of the handle part 1, and slides up and down along the handle part 1.

[0031] like Figures 1 to 6As shown, this technical solution utilizes the flexibility and wedge-shaped structure of the scraper section 3, combined with the lever principle of the inclined support section 4, to allow the scraper section 3 to deform according to the curvature of the inner wall of the tank, and the cleaning arc surface 31 to conform to curved surfaces of different diameters; the inclined support section 4 and the support point 2 form a stable structure similar to a triangle. When the sleeve section 5 slides, the angle of the inclined support section 4 is changed, causing the scraper section 3 to move from... Figure 1 The triangle becomes Figure 4 The fan-shaped design increases the curvature of the arc, enhancing the fit and achieving efficient cleaning. Specifically, the rubber scraper part 3 is deformable, working in conjunction with the cleaning arc surface 31 and the inclined support part 4 to closely fit the inner wall of the can with different curvatures, effectively scraping away powder residue; the sleeve part 5 can slide along the handle part 1, adjusting its position according to the can depth to meet the cleaning needs of cans of different sizes; the long-handled handle part 1 facilitates operation, reduces physical exertion during cleaning, and improves cleaning efficiency.

[0032] In addition, the inner wall cleaning tool adapted to complex curved surfaces proposed above according to this utility model may also have the following additional technical features: According to one embodiment of the present invention, the two inclined rods of the inclined support part 4 are symmetrically arranged at both ends of the scraper part 3, and the two inclined rods intersect at the sleeve part 5 to form a stable support structure.

[0033] In this technical solution, during the cleaning process, the scraper part 3 is subjected to the reaction force of the inner wall of the tank. The reaction force is transmitted to the sleeve part 5 through the inclined rod, and then dispersed by the connection between the sleeve part 5 and the hand-held part 1, forming a force balance and transmission path.

[0034] According to one embodiment of the present invention, the sleeve part 5 is provided with a locking inner sleeve. By rotating the locking inner sleeve, the sleeve part 5 can be locked at any height of the handheld part 1 to adapt to the cleaning needs of tanks of different depths.

[0035] In this technical solution, when the inner sleeve is rotated and locked, the contact pressure between the inner sleeve and the handle 1 and the sleeve part 5 is changed. By utilizing the principle of friction, sufficient resistance is generated between the sleeve part 5 and the handle 1, thereby locking the sleeve part 5 at any height of the handle 1 to adapt to the cleaning of tanks of different depths.

[0036] According to one embodiment of the present invention, the scraper part 3 is deformed under the action of the inclined support part 4, and the shape of the combination of the scraper part 3 and the inclined support part 4 changes from a triangle to a fan shape.
