Description

Technical Field

[0001] This utility model relates to the technical field of daily necessities such as household repair and maintenance coatings, and specifically to a painting device. Background Technology

[0002] In daily life and household maintenance, walls are prone to dirt, peeling, and paint loss; iron products are prone to rust; and wooden products are prone to discoloration. These problems are common and require timely repair to ensure a clean living environment and the normal use of items. Currently, the quality of repair products on the market for these problems varies greatly, especially in the field of wall repair. Most mainstream products are sold in large packages, and the repair process requires professional installation. Preparation work such as material preparation beforehand is also necessary, which is not only time-consuming and labor-intensive but also incurs high labor and material costs. Furthermore, for repair needs of small, localized areas of walls, large-package products and professional installation methods are not well-suited, making the repair process extremely inconvenient.

[0003] To improve the above situation, a roller-type paint applicator that is easy to use manually has emerged on the market. This device typically consists of a storage bottle, a brush holder, and a brush roller. The brush holder is attached to the mouth of the storage bottle, and the brush roller is mounted on the support of the brush holder. When using this device to repair walls, squeezing the bottle forces the paint to flow along the guide channel of the brush holder onto the brush roller. Then, like a regular roller, the paint is rolled back and forth on the wall to repair it. This allows for easy, everyday paint repairs by anyone, has a wide range of applications, and can reduce material waste and save costs to some extent. However, in actual use, this roller-type paint applicator still suffers from uneven paint application, failing to meet users' demands for high-quality repair results, and requires further improvement.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0023] like Figures 1 to 5As shown in the figure, this application provides a coating device, including: a bottle body 1, a coating frame 2, and a brush roller 3. The bottle body 1 has a bottle mouth 11. The coating frame 2 includes a connecting cylinder 21 and a support body 22. The support body 22 has a cavity, and a guide shell 221 is provided on the inner wall of the cavity. The guide shell 221 surrounds and forms an elongated guide cavity. The guide shell 221 has multiple protrusions 2211 on the edge of the opening of the guide cavity. The connecting cylinder 21 is connected to the support body 22 and is detachably connected to the bottle body 1. The connecting cylinder 21 connects the bottle mouth 11 and the guide cavity. The bottle body 1 and the coating frame 2 can be disassembled separately for convenient transportation and storage. The outer side of the bottle mouth 11 is provided with an external thread 111, and the inner wall of the connecting cylinder 21 is provided with an internal thread 211. The two can be connected by threads. When the bottle body 1 is connected to the coating frame 2, the external thread 111 is connected to the internal thread 211. When the bottle 1 is shipped from the factory or not in use, it contains paint or varnish and is sealed with a cap 4 to prevent leakage and facilitate transportation. In use, simply unscrew the cap 4, align the bottle opening 11 of the bottle 1 with the internal thread 211 on the connecting cylinder 21 and tighten it. The paint or varnish will then flow onto the brush roller 3 of the brush holder 2, thereby repairing the surface of damaged objects. After use, the bottle 1 can be unscrewed from the brush holder 2, and the cap 4 can be replaced for future use or storage. The brush roller 3 is rotatably connected to the support body 22. The brush roller 3 extends along the length of the guide cavity, with a portion of the brush roller 3 located in the recess. The brush roller 3 covers the opening of the guide cavity, and the protrusion 2211 contacts the rolling surface of the brush roller 3. The coating device of this application has multiple protrusions 2211 on the edge of the guide cavity opening that contact the brush roller 3. When the brush roller 3 rolls, the protrusions 2211 can dynamically comb the bristles and paint on the brush roller 3 like a comb, effectively preventing paint accumulation and uneven distribution, making the bristles and paint distribution more uniform and regular, thereby significantly improving the coating effect and efficiency and reducing rework. Moreover, the structure is simple and ingenious, easy to implement and low in cost, without increasing manufacturing costs too much, effectively reducing the operating threshold, improving the user experience, and facilitating large-scale promotion and application.

[0024] like Figure 3As shown, the guide shell 221 includes two elongated plates, which are spaced apart and arranged parallel to each other. The two ends of the two elongated plates are connected together, and the two ends of the two elongated plates are respectively connected by arc-shaped plates. The guide cavity is formed between the elongated plates. The protrusions 2211 are provided on the elongated plates, and each protrusion 2211 is arranged sequentially along the length direction of the elongated plate, that is, each protrusion 2211 is arranged along the length direction of the brush roller 3. When the brush roller 3 rolls, the protrusions 2211 can dynamically comb the bristles and paint on the surface of the brush roller 3 like a comb, so that the bristles and paint are more evenly and regularly distributed, thereby significantly improving the coating effect and efficiency.

[0025] The cross-section of the protrusion 2211 gradually decreases in the direction from the bottle body 1 to the brush holder 2. The protrusion 2211 is toothed, meaning its end is relatively small, allowing it to easily penetrate the bristles on the surface of the brush roller 3. This facilitates smoother guidance of the paint flow to the bristle roots, preventing paint accumulation. As the brush roller 3 rolls, it gently and precisely combs the bristles like a fine-toothed comb, further improving the uniformity and effectiveness of the coating.

[0026] The protrusions 2211 on the two long strips are positioned opposite each other, achieving uniform combing on both sides. This makes the distribution of the bristles and coating on the brush roller 3 more regular, while effectively controlling the coating thickness and providing stable support and guidance for the brush roller 3 to prevent it from shaking or deviating. Thus, while simplifying the structure, it significantly improves the uniformity and stability of the coating.

[0027] In one possible implementation, such as Figure 3 As shown, the bottom wall of the material guiding cavity is provided with multiple material holes 222. The material holes 222 connect the inner cavity of the connecting cylinder 21 and the material guiding cavity. Each material hole 222 is arranged at intervals along the length direction of the material guiding cavity, which can realize multi-point uniform material supply along the length direction of the brush roller 3, improving the coating uniformity. At the same time, the multiple dispersed material holes 222 can effectively reduce the risk of clogging and ensure stable material supply. Furthermore, the size and spacing of the material holes 222 can be optimized to achieve precise control of the output amount and adapt to different working conditions.

[0028] like Figure 3 As shown, the material hole 222 is an elongated hole extending along the length of the material guide cavity, which further increases the area of ​​the discharge channel and more effectively prevents blockage. At the same time, the elongated hole extends along the length of the brush roller 3, which can form a more uniform strip feeding in a local area, reduce the lateral fluctuation of the paint on the surface of the brush roller 3, make the paint coating thickness more consistent, and improve the brushing effect, effectively reducing the phenomenon of rework.

[0029] like Figure 3As shown, each of the material holes 222 includes a central material hole 2221 and two side material holes 2222. The central material hole 2221 is located at the middle of the guide cavity along its length, and the two side material holes 2222 are located on both sides of the central material hole 2221 along the length of the guide cavity. The central material hole 2221 is for direct spraying, and the side material holes 2222 are for side spraying, which can achieve full coverage of the brush roller 3. This ensures that the paint is evenly wetted from the center to both ends of the brush roller 3, effectively avoiding the problem of excessive thickness in the middle and dryness at the edges that may be caused by single-point feeding in traditional technology, and significantly improving the overall uniformity of the coating.

[0030] like Figure 3 As shown, a boss 223 is provided in the middle of the bottom wall of the material guiding cavity. The boss 223 includes a top shell 2231 and side inclined shells 2232 located on both sides of the top shell 2231. The central material hole 2221 is located on the top shell 2231, and the two side material holes 2222 are respectively provided on the side inclined shells 2232 on both sides. The side inclined shells 2232 can guide the paint to flow smoothly, reduce the risk of material accumulation and blockage in the cavity, realize three-dimensional and full-coverage material supply to the brush roller 3, ensure that the paint evenly wets the middle and both sides of the brush roller 3, and improve the coating uniformity.

[0031] In one possible implementation, such as Figure 3 As shown, scraper ribs 224 are provided in the concave cavity. The scraper ribs 224 are distributed on both sides of the guide shell 221 along the width direction. The top end face of the scraper ribs 224 is in contact with the rolling surface of the brush roller 3. When the brush roller 3 rolls, the scraper ribs 224 can continuously scrape off excess paint from the brush bristle surface, forcibly disperse it, effectively prevent local accumulation and dripping, thereby further ensuring uniform paint distribution on the surface of the brush roller 3 and improving the final coating quality.

[0032] like Figure 3 As shown, the scraper rib 224 includes multiple V-shaped ribs, each arranged sequentially along the length of the long strip and connected to the long strip. The V-shaped ribs and the long strip form a stable triangular structure, enhancing the strength and rigidity of the scraper rib 224 and preventing deformation during long-term friction. Simultaneously, the V-shaped tips of the ribs efficiently scrape away excess paint from the surface of the brush roller 3 and evenly distribute it along the inclined surface to the root of the bristles, effectively preventing material accumulation and dripping, further improving coating uniformity. Furthermore, the open space formed by the V-shaped structure of the ribs facilitates paint backflow, reducing the risk of clogging and improving the overall reliability and service life of the coating device of this application.

[0033] The preferred embodiments disclosed above are merely illustrative of this application. These preferred embodiments do not exhaustively describe all details, nor do they limit the application to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this application, thereby enabling those skilled in the art to better understand and utilize this application. This application is limited only by the claims and their full scope and equivalents.
