Description

Technical Field

[0001] This utility model relates to the technical field of paint auxiliary cleaning tools, and more specifically to a paint comb brush with a quick-change brush head. Background Technology

[0002] Paint cleaning tools include various tools such as paint combs and putty knives. They are used to clean and maintain the bristles of paint brushes and paint rollers, effectively removing residual paint, restoring the neat arrangement of the bristles, and ensuring a uniform effect for the next coat. Chinese patent CN216756923U discloses a multifunctional paint tool, which includes a blade and a handle. The handle is located at the bottom of the blade, and multiple spaced brush grooves are formed on one side edge of the blade. The blade portion between adjacent brush grooves forms a brush head. In use, the brush head is first inserted into the bristles, and then the blade is moved back and forth to separate the matted bristles, thus cleaning the bristles. This not only improves the ease of cleaning the bristles but also increases the efficiency of painting operations.

[0003] However, the blades and handles of the aforementioned paint cleaning tools are molded as a single piece. This type of molded structure has inherent defects: when the fixed blades remove residual paint from the brush bristles, the paint that falls off often sticks to the surface of the blades. In order to ensure the cleaning effect next time, the operator needs to remove the attached paint in time, which complicates the entire painting process and ultimately prolongs the painting cycle and reduces work efficiency. Utility Model Content

[0004] In response to the above situation, and to overcome the problem that the blade and handle of the aforementioned paint cleaning brush are molded as a single piece, requiring the timely removal of paint adhering to the blade surface after cleaning the bristles, thus complicating the entire painting process and ultimately extending the painting cycle and reducing work efficiency, the purpose of this utility model is to provide a paint comb brush with a separate handle and brush head design. This allows the brush head to be removed separately after the bristles are cleaned, saving waiting time for brush head cleaning by replacing it, thereby simplifying the painting process, shortening the painting cycle, and further improving work efficiency.

[0005] To achieve the above objectives, the technical solution of this utility model is:

[0006] A paint comb brush with a quick-change brush head includes a handle and a brush head. The upper end of the handle has a slot. The brush head is made of plastic. The right side of the brush head has paint-filtering teeth, and the lower end of the brush head has an insert block that is inserted into the slot. The insert block has a limiting flange on its outer wall, and a corresponding limiting groove is formed on the inner wall of the slot. The limiting flange and the limiting groove engage with each other.

[0007] Preferably, the inner diameter of the insert decreases sequentially from top to bottom.

[0008] Preferably, both the upper and lower sidewalls of the limiting flange are inclined surfaces.

[0009] Preferably, the handle is made of plastic.

[0010] Preferably, it also includes a hook located between the handle and the brush head.

[0011] Preferably, the hook includes a base and a hook body. The base has a sleeve hole, the lower end of the brush head has a mounting seat, the insert is located on the mounting seat, the base is fitted onto the mounting seat through the sleeve hole, and the upper and lower side walls abut against the brush head and the handle respectively. The hook body has two sets, and the two sets of hook bodies are spaced apart on the base.

[0012] Preferably, a paint filter port is provided on the left side of the brush head, the shape of which matches the shape of the paint roller, and a paint filter strip is formed on the side wall of the paint filter port along its direction.

[0013] Preferably, the filter teeth are conical in shape.

[0014] Preferably, the handle has a hanging hole.

[0015] Preferably, the lower end of the handle is also provided with a pry bar.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] After the bristles of this paint comb brush have been cleaned, the operator can apply axial tension to the brush head or handle. Under the action of axial tension, the limiting flange will be compressed and deformed again by the inner wall of the limiting groove, so that the insert can be smoothly disengaged from the slot, thereby separating the brush head from the handle. This ensures that the brush head can be quickly replaced. After the bristles have been cleaned, the waiting time for brush head cleaning can be saved by replacing the brush head, thereby simplifying the painting process, shortening the painting cycle, and further improving the efficiency of the painting operation.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the purpose of simplifying the description and do not indicate or imply that the orientation is a specific orientation or specific orientation structure and operation. Therefore, they should not be construed as limiting this utility model.

[0029] like Figures 1 to 6As shown, this utility model relates to a paint comb brush with a quick-change brush head. It includes a handle 1 and a brush head 2. The upper end of the handle 1 has a slot 101 that extends along the axial direction of the handle 1 but does not penetrate the lower end of the handle 1. The brush head 2 is made of plastic. The right side of the brush head 2 has paint filtering teeth 201. The number of paint filtering teeth 201 is not particularly limited. Each paint filtering tooth 201 is arranged sequentially at intervals along the length of the brush head 2, and a paint filtering groove is formed between adjacent paint filtering teeth 201. By inserting the paint filtering teeth 201 into the bristles of the paint application tool, the bristles are guided into the paint filtering groove to separate the matted bristles. The brush head 2 slides back and forth along the bristles. The paint can be scraped off by the filter teeth 201 on both sides of the filter tank, thus cleaning the brush bristles, reducing the difficulty of cleaning the bristles and improving the efficiency of painting operations. A plug 202 is formed at the lower end of the brush head 2, which is inserted into the slot 101 of the handle 1. The plug 202 and the slot 101 are engaged to connect the brush head 2 and the handle 1. Furthermore, a limiting flange 202a is formed on the outer wall of the plug 202, and a corresponding limiting groove 101a is formed on the inner wall of the slot 101. The limiting flange 202a and the limiting groove 101a are engaged with each other. The walls will abut against each other to limit each other, thereby preventing relative axial movement between the brush head 2 and the handle 1, and ensuring a tight fixation between the brush head 2 and the handle 1. It should be noted that the limiting flange 202a does not affect the insertion of the insert block 202 into the slot 101. Because the brush head 2 is made of plastic, it has elastic deformation capability. When the insert block 202 is inserted into the slot 101, it is subjected to pressure from the inner wall of the slot 101, causing the insert block 202 to undergo a certain elastic deformation, temporarily compressing the limiting flange 202a. Once the insert block 202 is fully inserted, the limiting flange 202a is positioned opposite the limiting groove 101a. At this point, the pressure on the inner wall of the slot 101 is released, and the limiting flange 202a... 02a can self-recover and insert into the limiting slot 101a, achieving a stable connection between the handle 1 and the brush head 2. The operator can apply axial tension to the brush head 2 or the handle 1. Under the action of axial tension, the limiting flange 202a will be compressed and deformed again by the action of the inner wall of the limiting slot 101a, so that the insert 202 can be smoothly disengaged from the slot 101, thereby separating the brush head 2 from the handle 1 and ensuring that the brush head 2 can be replaced. After the bristles are cleaned, the waiting time for cleaning the brush head 2 can be saved by replacing the brush head 2, thereby simplifying the painting operation process, shortening the painting operation cycle, and further improving the efficiency of the painting operation.

[0030] like Figure 2 , Figure 3 and Figure 6As shown, the inner diameter of the insert 202 decreases from top to bottom, meaning that the cross-sectional shape of the insert 202 is a frustum. When the brush head 2 is assembled, the lower end of the insert 202 with the smaller inner diameter enters the slot 101 first, which can effectively reduce the centering deviation, achieve smoother positioning and insertion, and reduce the difficulty of assembling the brush head 2.

[0031] like Figure 3 As shown, the upper and lower sidewalls of the limiting flange 202a are both inclined surfaces, and the cross-sectional shape of the limiting slot 101a matches the cross-sectional shape of the limiting flange 202a. That is, the top and bottom walls of the limiting slot 101a are both inclined surfaces. When the limiting flange 202a is inserted into the limiting slot 101a, its inclined surfaces will play a guiding role. The force is transmitted to the insert block 202 through the limiting flange 202a, effectively converting the axial force during insertion into the pushing force, accelerating the speed at which the insert block 202 is inserted into the slot 101. At the same time, when the brush head 2 is removed, the top and bottom walls of the limiting flange 202a will also provide guidance for the limiting flange 202a, enabling the limiting flange 202a to be quickly removed, thereby optimizing the smoothness of the insertion and removal process.

[0032] Furthermore, both the handle 1 and the brush head 2 are made of plastic. When the insert 202 is inserted into the slot 101, the inner wall of the slot 101 presses against the limiting flange 202a, while the slot 101 itself expands and deforms due to the reaction force. In other words, bidirectional elastic deformation will occur during the assembly process, which not only effectively buffers the resistance during the assembly process, but also adjusts the fitting gap through dynamic deformation, making the insertion process smoother and significantly improving the operating experience of assembling the brush head 2.

[0033] like Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, it also includes a hook 3, which is located between the handle 1 and the brush head 2. The hook 3 can be fastened to the edge of the opening of various paint containers, so that the paint comb brush of this utility model can be stably attached to the paint container, realizing integrated carrying with the paint container, thereby solving the problem of difficulty in unified storage due to the large variety of tools in the painting process, and improving the convenience of painting operations.

[0034] like Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7As shown, the hook 3 consists of a base part 301 and a hook part 302. The base part 301 has a sleeve hole 301a. A mounting base 203 is formed at the lower end of the brush head 2. The mounting base 203 and the brush head 2 insert 202 are located on the mounting base 203. The base part 301 is fitted onto the mounting base 203 through the sleeve hole 301a. When the insert 202 is inserted into the slot 101 of the handle 1, the mounting base 203 is exposed to the external space. Thus, the base part 301 fitted onto the mounting base 203 will... The base 301 is clamped by the handle 1 and the brush head 2, meaning that the upper and lower side walls of the base 301 abut against the brush head 2 and the handle 1 respectively. The hook part 302 has two sets, which are spaced apart on the base 301. The hook 3 is fastened to the edge of the paint container opening by the two sets of hook parts 302, forming two points of force. The interval between the two hook parts 302 can effectively distribute the bearing pressure and prevent the hook 3 from shaking and slipping due to unilateral force, which significantly improves the fixed stability of the hook 3 at the edge of the container.

[0035] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, a paint filter port 204 is provided on the left side of the brush head 2. The shape of the paint filter port 204 matches the shape of the paint roller, that is, the shape of the paint filter port 204 is a semi-circular opening. Its size can be configured to different sizes to accommodate paint rollers of different diameters. A paint filter strip 204a is formed along the direction on the side wall of the paint filter port 204. Through the paint filter port 204, the paint comb brush of this utility model can also be used to clean the bristles of the paint roller. Simply insert the paint roller into the paint filter port 204. At this time, the paint filter strip 204a abuts against the outer wall of the paint roller. Then, control the brush head 2 to move along the axial direction of the paint roller to scrape off the paint adhering to the paint roller, thereby cleaning the paint roller bristles. The above configuration makes the paint comb brush of this utility model have the dual function of cleaning paint rollers, significantly improving the versatility of functions.

[0036] like Figure 1 , Figure 4 and Figure 6 As shown, the paint filter teeth 201 are conical in shape. More specifically, the free ends of the paint filter teeth 201 are conical, making them sharper. This design is more conducive to separating the clumped bristles through the paint filter teeth 201. During cleaning, the sharp free ends of the paint filter teeth 201 preferentially penetrate the bristles, quickly separating the sticky bristles. This not only reduces the initial resistance but also allows the force to be quickly transmitted to the root of the bristles, significantly improving the efficiency of separation and cleaning and greatly optimizing the effortless feeling during cleaning.

[0037] like Figure 1 , Figure 2 and Figure 4As shown, a hook is provided on the handle 1, and the hanging hole 102 provides another way to store the paint comb brush of this utility model. It can be directly hooked onto objects such as wall hooks and tool racks through the hanging hole 102 to achieve three-dimensional hanging storage, thereby saving space on the display surface, solving the problem of temporary placement after use, and ensuring neat and orderly storage, greatly improving the convenience of daily use and storage.

[0038] like Figure 1 , Figure 4 and Figure 5 As shown, the lower end of the handle 1 is also provided with a pry bar 4, which is made of metal. Operators can use the pry bar 4 to easily open the sealed paint container. The pry bar 4 can also be used as an emergency scraper to remove stubborn paint, thus better handling the needs of opening the can and removing paint. This not only enriches the functions of the paint comb brush of this utility model, but also simplifies the extra tools required for painting operations, and greatly improves the efficiency of painting operations.

[0039] Combination Figures 1 to 7 This utility model paint brush has multiple functions. Operators can insert the paint-filtering teeth 201 on the brush head 2 into the bristles of the paint application tool, guiding the bristles into the paint filter groove to separate the matted bristles. By sliding the brush head 2 back and forth along the bristles, the paint-filtering teeth 201 on both sides of the filter groove can scrape off the paint adhering to the bristles, thus cleaning the bristles. Alternatively, a paint roller can be embedded into the paint filter port 204 of the brush head 2. By using the paint filter strip 204a to abut against the outer wall of the paint roller, and controlling the brush head 2 to move axially along the paint roller, the paint adhering to the paint roller can be scraped off, thus cleaning the paint roller bristles. The sealed paint container can also be easily opened using the pry bar 4 at the lower end of the handle 1, or it can be used as an emergency scraper to remove stubborn paint. Furthermore, it offers various storage options, including using the hook 3... The hook part 302 is fastened to the edge of the paint container opening and bound to the paint container, enabling simultaneous carrying with the paint container. It can also be hooked to wall hooks, tool racks, and other objects using the hanging hole 102 on the handle 1, achieving three-dimensional hanging storage. In addition, the handle 1 and the brush head 2 adopt a detachable design with a plug-in connection. After the brush is cleaned, the operator can apply axial tension to the brush head 2 or the handle 1. Under the action of axial tension, the limiting flange 202a will be compressed and deformed again by the action of the inner wall of the limiting groove 101a, so that the plug 202 can be smoothly disengaged from the slot 101, thereby separating the brush head 2 from the handle 1 and ensuring that the brush head 2 can be replaced. After the bristles are cleaned, the waiting time for cleaning the brush head 2 can be saved by quickly replacing the brush head 2, thereby simplifying the painting operation process and shortening the painting operation cycle.
