Description

Technical Field

[0001] This utility model relates to the field of coating application tools, specifically a waterproof coating roller brush. Background Technology

[0002] In building waterproofing projects and home decoration waterproofing treatments, the application of waterproof coatings is crucial. Currently, the most common tools for applying waterproof coatings on the market are ordinary roller brushes, which have revealed many problems in actual use.

[0003] On the one hand, traditional roller brushes often struggle to precisely control the amount of paint used. If too much paint is used, it can easily drip and accumulate during application, resulting in waste, uneven coating thickness on walls or floors, and compromised waterproofing. On the other hand, if too little paint is used, frequent re-painting is required, reducing work efficiency.

[0004] On the other hand, due to different construction scenarios and varying coating characteristics, sometimes a faster discharge speed is needed to improve the efficiency of large-area construction, while at other times a slower discharge is required to finely handle edges and corners. However, traditional roller brushes cannot flexibly adjust the discharge rate according to actual construction needs, making it difficult to meet diverse construction requirements.

[0005] In summary, existing waterproof coating roller brushes have significant shortcomings in terms of material output control, and there is an urgent need to develop a new type of waterproof coating roller brush that can effectively adjust the output, improve construction convenience and quality. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a waterproof coating roller brush.

[0007] The technical solution adopted by this utility model is: a waterproof coating roller brush, including a handle and a roller brush mechanism rotatably connected to the handle. The roller brush mechanism includes an inner cylinder, a bristle cylinder, and a knob. The bristle cylinder is rotatably fitted outside the inner cylinder. A valve plate and several discharge holes are provided on the inner wall of the bristle cylinder. The inner cylinder has a storage cavity for storing coating liquid, and the inner cylinder is provided with a discharge groove that seals with the valve plate. By rotating the knob to rotate the inner cylinder, the relative position of the valve plate can be controlled to control the opening degree of the discharge groove.

[0008] Furthermore, a material passage gap is left between the brush tube and the inner tube.

[0009] Furthermore, a sealing ring is provided at the connection between the inner cylinder and both ends of the brush tube.

[0010] Furthermore, a positioning indicator spring is fixed on the knob, and positioning bosses are spaced apart on the end face of the brush tube located at one end of the knob.

[0011] Furthermore, the outer ring of the knob is provided with several raised ridges at intervals.

[0012] Furthermore, a feed inlet is provided at one end of the inner cylinder, and a one-way valve is provided at the feed inlet.

[0013] The beneficial effects of this utility model are:

[0014] 1. Precise control of paint output: Rotating the knob drives the inner cylinder to rotate, thereby controlling the relative position of the valve plate and the long discharge chute, achieving precise control of the chute's opening. This allows operators to precisely adjust the paint output according to actual needs during painting operations. Whether it's large-area painting requiring more paint or delicate finishing of edges and corners requiring less, it easily handles the situation, avoiding waste caused by excessive paint application and the problems of dripping and accumulation affecting the painting effect. It also reduces the hassle of frequently dipping the brush due to insufficient paint application, effectively improving construction efficiency.

[0015] 2. Meeting Diverse Construction Needs: Given the varying requirements for dispensing speed across different construction scenarios and coating characteristics, the adjustable dispensing design of this invention can flexibly adapt to these diverse needs. During large-area construction, the opening of the dispensing trough can be appropriately increased to accelerate dispensing and improve construction efficiency; while when dealing with details such as edges and corners, the opening of the dispensing trough can be reduced to allow for slow dispensing of the coating, achieving fine application and ensuring the overall quality of the waterproofing project.

[0016] 3. Simple structure and easy operation: The entire drum brush mechanism has a simple and clear design. The output volume can be adjusted simply by rotating the knob. Compared with traditional drum brushes, no complicated operating procedures or additional auxiliary tools are required, allowing construction personnel to quickly get started, greatly improving the convenience of construction and reducing the difficulty of construction.

[0017] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0025] This utility model provides a waterproof coating roller brush.

[0026] In this embodiment, refer to Figure 1-4 The waterproof coating roller brush includes a handle 1 and a roller brush mechanism rotatably connected to the handle 1. The roller brush mechanism includes an inner cylinder 2, a bristle cylinder 3, and a knob 4. The bristle cylinder is rotatably fitted outside the inner cylinder. A valve plate 5 and several discharge holes 6 are provided on the inner wall of the bristle cylinder. The inner cylinder 2 has a storage cavity 7 for storing coating liquid, and the inner cylinder is provided with a discharge groove 8 that seals with the valve plate. By rotating the knob to rotate the inner cylinder, the relative position of the valve plate can be controlled to control the opening degree of the discharge groove.

[0027] The roller brush mechanism described above includes an inner cylinder, a brush tube, and a knob. The brush tube is rotatably fitted onto the outer side of the inner cylinder. The inner cylinder has a storage chamber for storing paint liquid and a discharge trough. The inner wall of the brush tube has a valve plate and a discharge hole. Rotating the knob drives the inner cylinder to rotate, thereby controlling the relative position of the valve plate to adjust the opening of the discharge trough, allowing for precise control of the paint discharge rate. This design overcomes the problem of traditional roller brushes being unable to flexibly adjust the discharge rate according to construction needs. It can adjust the discharge speed according to different construction scenarios, avoiding excessive paint waste or uneven coating thickness due to unstable application, effectively improving construction quality and efficiency while ensuring coating effect and waterproof performance.

[0028] Specifically, a material passage gap 9 is left between the brush tube and the inner tube.

[0029] In this embodiment, a material passage gap is left between the brush tube and the inner tube, allowing the paint to flow more smoothly and evenly to various positions of the brush tube after flowing out from the inner tube storage cavity through the discharge channel. Finally, it flows out evenly from the discharge hole, ensuring that the brush bristles can continuously and stably obtain paint, avoiding paint blockage or local accumulation in the tube, further ensuring the uniformity of paint discharge, which is conducive to improving the painting effect, ensuring the quality of the painted surface, and enabling the paint to adhere more evenly to the construction surface such as the wall or floor during the painting process, laying the foundation for obtaining a good waterproof effect.

[0030] Specifically, a sealing ring 10 is provided at the connection between the inner cylinder and both ends of the brush tube.

[0031] In this embodiment, a sealing ring is provided at the connection between the inner cylinder and the brush tube at both ends. Its main function is to prevent the paint from leaking from the connection between the inner cylinder and the brush tube.

[0032] Specifically, a positioning indicator spring 11 is fixed on the knob, and positioning bosses 12 are spaced apart on the end face of the brush tube located at one end of the knob.

[0033] In this embodiment, a positioning indicator spring is fixed to the knob, and positioning bosses are spaced apart on the end face of the brush tube at one end of the knob. This design facilitates the operator to accurately adjust and position the opening of the discharge chute. The positioning indicator spring and the positioning bosses work together to allow the user to intuitively and accurately adjust the discharge amount to the required opening, avoiding fluctuations in paint discharge amount caused by inaccurate adjustment, improving the convenience and accuracy of operation, reducing paint waste or poor construction results caused by operational errors, and providing convenience for quickly and accurately adjusting the discharge amount during construction.

[0034] Specifically, the outer ring of the knob is provided with several protruding ridges 13 at intervals.

[0035] In this embodiment, several raised ridges are spaced apart on the outer ring of the knob, increasing the knob's friction and feel, making it easier for the operator to rotate the inner cylinder. During use, especially when hands are covered in paint, the raised ridges prevent slippage, allowing users to rotate the knob more easily and stably, facilitating the adjustment of the discharge volume, ensuring operational reliability and stability, and improving construction efficiency.

[0036] Specifically, a feed inlet 14 is provided at one end of the inner cylinder, and a one-way valve is provided on the feed inlet 14.

[0037] In this embodiment, an inlet 14 is provided at one end of the inner cylinder, and a one-way valve is installed on the inlet to ensure that the paint can be easily injected into the inner cylinder storage chamber, while preventing the paint in the storage chamber from flowing back from the inlet. This design facilitates the replenishment of paint during construction, ensures the continuity of construction, and avoids paint waste and pollution of the construction area caused by backflow. It helps to improve the convenience of construction and the overall construction efficiency, making the paint storage and replenishment process more scientific and reasonable.
