Description

Technical Field

[0001] The utility model relates to the field of paint brushes, and more specifically, to a cylindrical paint brush head shell. Background Art

[0002] There are many types of paint brushes. Different types of paint brushes can be selected according to different uses and coating materials. Generally speaking, paint brushes can be divided into wall brushes, paint brushes, varnish brushes, etc. Paint brushes are a commonly used painting tool, which is composed of a brush handle and a brush head. At present, cylindrical brush heads are commonly used. Compared with other types of brush heads, it is easier to control the brush strokes and is convenient for operation. Multiple holes are opened on the brush head to fix the bristles in the holes so that the bristles are evenly distributed.

[0003] Currently, there are two common hole shapes: rectangular holes and round holes. Rectangular holes help to accurately paint corners and edges and improve the accuracy of painting, while round holes help to more evenly distribute the bristles, allowing the brush head to paint more smoothly when painting, reducing bubbles or unevenness in the coating. The shapes of the holes on the traditional brush head shell are generally the same, which leads to certain limitations during use. For example, if all holes are rectangular, the paint is not evenly applied. Similarly, if all holes are round, the effect of painting corners and edges is not very good.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a cylindrical paint brush head housing having both a rectangular hole and a circular hole. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a cylindrical paint brush head housing.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: it includes a cylindrical shell with upper and lower openings, a bottom plate is provided inside the cylindrical shell, a side plate connected to the bottom plate is fixedly connected to the upper opening of the cylindrical shell, a plurality of rectangular holes are provided on the edge of the side plate, the holes penetrate the side plate and are surrounded by the inner wall of the cylindrical shell, a plurality of circular holes arranged in an array and penetrate the side plate are provided on the surface of the side plate in the internal area surrounded by the rectangular holes, bristles are inserted into the rectangular holes and the circular holes, and the bristles extend outside the cylindrical shell.

[0007] Preferably, the rectangular hole on the side plate is lower in height than the circular hole.

[0008] Preferably, a cylindrical protrusion is integrally formed at the center of the top end of the side plate, and the circular hole covered by the cylindrical protrusion passes through the cylindrical protrusion upward, so that the bristles can pass through the cylindrical protrusion upward along the circular hole.

[0009] Preferably, the spacing between the circular holes is between 0.5 mm and 3 mm, thereby improving cleaning efficiency and reducing wear of bristles.

[0010] Preferably, the cylindrical shell is detachably connected to a cover body, and after the cover body is installed on the shell, the cover body can isolate the bristles from the outside world to prevent the bristles from being contaminated with dust when not in use, thereby affecting its normal use.

[0011] Preferably, a thread is provided on the opening portion on the outer wall of the shell corresponding to the side plate, and a threaded connection is formed with the inner wall of the cover body through the thread. The cover body can be installed on the shell by just rotating it, and can be disassembled by rotating it in the opposite direction, which makes disassembly and assembly relatively simple.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The bristles on the side panel of the utility model are separated by rectangular holes on all sides and circular holes in the middle, so that the bristles in the rectangular holes on all sides can accurately paint the corners and edges, while the bristles in the circular holes can help to distribute the bristles more evenly, so that the brush head can paint more smoothly when brushing, reducing bubbles or unevenness in the coating. In this way, by improving the brush head shell, the performance of the brush head can be significantly improved, thereby solving the problem that the holes of a single shape in the background technology have certain limitations during use.

[0014] 2. The length of the bristles extending from the hole of the utility model decreases from the outside to the inside, so that the mobility increases from the inside to the outside, which better meets the requirements for the mobility of the bristles when using a paint brush to paint, making it easier to paint.

[0022] like Figure 1 and 2 As shown, a first embodiment of a paint brush head housing is shown: it comprises a cylindrical housing 1 with upper and lower openings, a bottom plate 2 is arranged inside the cylindrical housing 1, a side plate 3 connected to the bottom plate 2 is fixedly connected to the upper opening of the cylindrical housing 1, a plurality of rectangular holes 4 are arranged on the edge of the side plate 3, which penetrate the side plate 3 and are surrounded by the inner wall of the cylindrical housing 1, a plurality of circular holes 5 arranged in an array and penetrate the side plate 3 are arranged on the surface of the side plate 3 in the inner area surrounded by the rectangular holes 4, bristles are inserted into the rectangular holes 4 and the circular holes 5, and the bristles extend outside the rectangular housing 1. According to the above description, the brush head with the cylindrical housing 1 can apply paint more evenly because it It is able to maintain a consistent contact area, thereby reducing uneven coating, and the bristles on the side panel 3 are separated by the rectangular holes 4 on all sides and the circular hole 5 in the middle, so that the bristles fixed in the rectangular holes 4 on all sides can accurately paint corners and edge parts (since the advantage of fixing the bristles in the rectangular holes 4 is that it is convenient to accurately paint corners and edge parts, they are designed to be placed around the side panel 3 to make the brush head more convenient to operate), and the bristles fixed in the circular hole 5 can help to distribute the bristles more evenly, so that the brush head can paint more smoothly when brushing, reducing bubbles or unevenness in the coating. In this way, the performance of the brush head can be significantly improved by improving the brush head housing.

[0023] Furthermore, the height of the rectangular hole 4 on the side panel 3 is set lower than the circular hole 5, so that the length of the bristles in the rectangular hole 4 is longer. In this way, when the paint brush is tilted for painting (the paint brush generally needs to be slightly tilted when painting, which can help the paint to better adhere to the painting surface, especially in corners or edges), the bristles in the outer circle extend longer from the rectangular hole 4, are more active, and have a larger contact area with the paint object, making it easier for workers to perform painting operations.

[0024] In addition, a cover body is detachably connected to the cylindrical shell 1. After the cover body is installed on the shell 1, the cover body can isolate the bristles from the outside world to prevent the bristles from being contaminated with dust when not in use, thereby affecting its normal use.

[0025] The specific method of disassembly is as follows: a thread 7 is provided on the opening portion corresponding to the outer wall of the shell 1 and the side plate 3, and a threaded connection is formed with the inner wall of the cover body through the thread 7. In this way, the cover body can be installed on the shell 1 by simply rotating it, and the cover body can be disassembled by rotating it in the opposite direction. The disassembly and assembly is relatively simple.

[0026] like Figure 3 and Figure 4 As shown, a second embodiment of the paint brush head shell is shown. The difference between the second embodiment and the first embodiment is that a cylindrical protrusion 6 is integrally formed at the center of the top end of the side panel 3, and the circular hole 5 covered by the cylindrical protrusion 6 passes upwardly through the cylindrical protrusion 6, so that the bristles can pass through the cylindrical protrusion 6 upward along the circular hole 5, thereby deepening the circular hole 5 closest to the middle part of the side panel 3. The length of the bristles extending from the hole decreases from the outside to the inside, so that the activity increases from the inside to the outside, which is more in line with the requirements for the activity of the bristles when using a paint brush to paint (the activity requirements for painting at a slight tilt), making it easier to paint.

[0027] At the same time, when producing the paint brush head shell, different sizes of cylindrical shells 1 can be selected according to processing needs (large-scale processing requires manufacturing a larger cylindrical shell 1 to accommodate more bristles), as well as the spacing between the circular holes 5 on the cylindrical shell 1. The gap size between the circular holes 5 is preferably between 0.5mm and 3mm. After daily use, it seems that this gap can ensure that the bristles have enough space to move, thereby improving cleaning efficiency and reducing bristle wear.

[0028] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
