Description

Technical Field

[0001] This utility model relates to the technical field of the construction industry, specifically to a brush head that produces uniform material output. Background Technology

[0002] Painting walls is a process in which people use paint and tools to coat and protect the walls during the decoration process, and it is mostly done using roller brush sets. However, with the diversification of usage needs and the increasing complexity of real-world construction environments, traditional large-format roller brush sets are clearly unable to meet the needs of small-area wall repairs and painting in confined spaces.

[0003] In recent years, with the further development of related technologies, researchers in related industries have developed small roller brush devices with the same basic structure as the existing ones but smaller in size. The miniaturized brush head can better control the painting area, but it is also incompatible with the existing direct immersion and feeding method. Furthermore, direct manual application will cause the paint material to drip into the usage environment, wasting materials and causing pollution to the usage environment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a brush head with uniform material output, thus solving the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a brush head with uniform material output, including an elastic brush head sleeve plate and a roller brush head. An internally threaded cylinder is fixed to the bottom of the elastic brush head sleeve plate. An annular transition cylinder and a transition cover plate are fitted inside the bottom of the elastic brush head sleeve plate. The transition cover plate is snapped into the top inner side of the annular transition cylinder. A first material output groove is opened at the bottom of the elastic brush head sleeve plate, which makes the internal space of the internally threaded cylinder communicate with the internal space of the annular transition cylinder. The number of the first material output grooves 5 is not less than two and they are arranged in a straight line on the bottom structure of the elastic brush head sleeve plate 1.

[0006] The transition cover plate has an internal discharge space that communicates with the internal space of the annular transition cylinder. The discharge space consists of several discharge holes, which are divided into two equal parts and arranged from the center of the transition cover plate to both ends in a manner with fewer holes in the middle and more holes at both ends, so that the coating is evenly diffused from the center to both ends when the coating is discharged from the transition cover plate.

[0007] Assembly holes are provided on the side walls of both sides of the top of the elastic brush head cover plate. The roller brush head can be fitted inside the elastic brush head cover plate and can be movably connected to the top surface of the transition cover plate. The ends of the roller brush head are respectively engaged inside the two assembly holes.

[0008] Preferably, the annular transition cylinder includes an annular cylinder body and an annular limiting ring, and the annular limiting ring is fixedly nested inside the top of the annular cylinder body.

[0009] The transition cover plate includes a cover plate body and a connecting plate, with the bottom of the cover plate body fixed to the top of the connecting plate. The second discharge chute is opened in the middle inner side of the cover plate body and is in a through-hole position.

[0010] Preferably, the top of the connecting plate is provided with a locking groove, and the locking groove can be engaged with the annular limiting ring after the annular transition cylinder and the transition cover are assembled. Both sides of the cover body are provided with inclined guide arc surfaces.

[0011] Preferably, there are at least two first discharge troughs arranged in a straight line at the bottom of the elastic brush head sleeve plate.

[0012] Preferably, the discharge space is formed by a second discharge trough, which penetrates the transition cover plate and communicates with the internal space of the annular transition cylinder.

[0013] Preferably, the second discharge trough is located in the middle of the cover plate body, and the two ends of the second discharge trough extend into the areas of the two inclined guide arc surfaces.

[0014] Preferably, the bottom of the elastic brush head sleeve is provided with a linkage disassembly component. The linkage disassembly component includes a support sleeve. The support sleeve is fixedly sleeved inside the structure at the bottom of the elastic brush head sleeve and communicates with the internal space of the annular cylinder body. A first sealing ring is fixedly nested inside the support sleeve and a T-shaped rod is movably sleeved thereon. One end of the T-shaped rod is engaged inside the first sealing ring and seals the internal space of the first sealing ring. A spring is installed between the bottom of the T-shaped rod and the bottom surface of the support sleeve.

[0015] Preferably, the bottom of the support sleeve extends to the outer side of the bottom of the elastic brush head sleeve and is provided with external threads. A spring is fixed to the outer side of the bottom of the T-shaped rod, and a combined sealing cylinder that is spirally locked to the outer side of the bottom of the support sleeve is engaged with the outer side of the top of the spring.

[0016] Preferably, a second sealing ring is fitted on the outer top of the T-shaped sealing cylinder, and the surface of the second sealing ring is in close contact with the inner wall of the combined sealing cylinder.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This utility model comprises a flexible brush head sleeve, an internally threaded cylinder, an annular transition cylinder, a transition cover plate, a first discharge groove, and several discharge holes, forming a multifunctional output brush head. When used in conjunction with a roller brush head, the internally threaded cylinder has no specific requirements for the container holding the liquid raw material; it only needs to be able to spirally lock with the internally threaded cylinder and possess a certain degree of elasticity, thus having a wide range of applications. During the actual discharge process, the annular transition cylinder provides a centralized buffer space, and the transition cover plate, using its own arc-shaped top surface and two inclined guide arc surfaces, expands and spreads the liquid raw material output from the annular transition cylinder through the several discharge holes, ensuring the contact area with the roller brush head fitted inside the flexible brush head sleeve, improving feeding efficiency. Furthermore, the staggered arrangement of the several discharge holes on the transition cover plate allows the coating to be evenly output while ensuring that the flow rate is not too high, preventing dripping.

[0019] 2. This utility model consists of an elastic brush head sleeve, an internal threaded cylinder, an annular transition cylinder, a transition cover plate, a first discharge trough, and a second discharge trough, forming another multifunctional output brush head. When used in combination with a roller brush head, the internal threaded cylinder does not have specific requirements for the container holding the liquid raw material, as long as it can be spirally locked with the internal threaded cylinder and has a certain degree of elasticity, making it widely applicable. In the specific discharge process, the annular transition cylinder provides a centralized buffer space, and the transition cover plate uses its own arc-shaped top surface and two inclined guide arc surfaces to expand and spread the liquid raw material output by the annular transition cylinder through the second discharge trough, ensuring the contact area with the roller brush head fitted inside the elastic brush head sleeve and improving the feeding efficiency.

[0020] 3. The multifunctional output brush head of this utility model, during the feeding process of the roller brush head, the liquid raw material is in a relatively closed clearance space composed of the elastic brush head sleeve plate and the annular transition cylinder, which can effectively reduce the liquid raw material dripping into the use environment and optimize the painting operation effect.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example 1

[0038] Please see Figures 1-9 , Figure 14A brush head with uniform material output includes an elastic brush head sleeve plate 1 and a roller brush head 6. An internally threaded cylinder 2 is fixed to the bottom of the elastic brush head sleeve plate 1. An annular transition cylinder 3 and a transition cover plate 4 are fitted inside the bottom of the elastic brush head sleeve plate 1. The transition cover plate 4 is snapped into the top inner side of the annular transition cylinder 3. A first discharge groove 5 is opened at the bottom of the elastic brush head sleeve plate 1 to communicate with the internal space of the internally threaded cylinder 2 and the internal space of the annular transition cylinder 3. The number of first discharge grooves 5 is not less than two and they are arranged in a straight line at the bottom structure of the elastic brush head sleeve plate 1.

[0039] The annular transition cylinder 3 includes an annular cylinder body 31 and an annular limiting ring 32, and the annular limiting ring 32 is fixedly nested inside the top of the annular cylinder body 31. The transition cover plate 4 includes a cover plate body 41 and a connecting plate 42, and the bottom of the cover plate body 41 is fixed to the top of the connecting plate 42. The second discharge groove 8 is opened inside the middle part of the cover plate body 41 and is in a through-hole state.

[0040] The top of the connecting plate 42 is provided with a locking groove 44, and the locking groove 44 can engage with the annular limiting ring 32 after the annular transition cylinder 3 and the transition cover plate 4 are assembled. Both sides of the cover plate body 41 are provided with inclined guide arc surfaces 43.

[0041] The interior of the transition cover plate 4 is provided with a discharge space that communicates with the interior space of the annular transition cylinder 3. The discharge space consists of several discharge holes 9, which are divided into two equal parts and arranged from the center of the transition cover plate 4 to both ends in a manner with fewer holes in the middle and more holes at both ends, so that the coating is evenly diffused from the center to both ends when the coating is discharged from the transition cover plate 4.

[0042] The side walls on both sides of the top of the elastic brush head cover plate 1 are provided with assembly holes. The roller brush head 6 can be fitted inside the elastic brush head cover plate 1 and can be movably connected to the top surface of the transition cover plate 4. The ends of the roller brush head 6 are respectively snapped into the two assembly holes.

[0043] In use, there are no specific requirements for the container holding the liquid material, as long as it can be screwed together with the internal threaded cylinder 2 and has a certain degree of elasticity, such as the commonly used spring water bottle in the prior art. When painting the target area on the wall, the spring water bottle containing the liquid material is screwed together with the internal threaded cylinder 2. After completion, the spring water bottle is held and squeezed, and the pressurized liquid material inside the spring water bottle enters the interior of the annular cylinder body 31 through the first discharge groove 5, and then diffuses to the arc-shaped top surface of the cover plate body 41 through several discharge holes 9. The dense arrangement on both sides and sparse arrangement in the center of the transition cover plate 4 allows the paint to spread faster on both sides of the transition cover plate 4 compared to the center, optimizing the uniform discharge effect. Subsequently, the inclined guide arc surfaces 43 on both sides of the cover plate body 41 will further guide and expand the liquid material, thus making full contact with the bottom surface of the roller brush head 6. At the same time, the roller brush head 6 is rolled on the target area on the wall, so that the liquid material covering the surface of the roller brush head 6 is coated on the target area, thereby achieving the painting effect. The subsequent periodic squeezing and rolling operations can be completed.

[0044] Example 2

[0045] Please see Figures 12-13 The discharge space is formed by the second discharge trough 8, which penetrates the transition cover plate 4 and communicates with the internal space of the annular transition cylinder 3. The second discharge trough 8 is located in the middle of the cover plate body 41, and the two ends of the second discharge trough 8 extend into the area of ​​the two inclined guide arc surfaces 43 respectively.

[0046] In use, there are no specific requirements for the container holding the liquid material. It only needs to be able to be screwed together with the inner threaded cylinder 2 and have a certain degree of elasticity, such as the commonly used water bottle in the prior art. When the target area on the wall needs to be painted, the water bottle containing the liquid material is screwed together with the inner threaded cylinder 2. After completion, the water bottle is held and squeezed, and the liquid material under pressure in the water bottle will enter the interior of the annular cylinder body 31 through the first discharge channel 5. Then, it will spread to the arc-shaped top surface of the cover plate body 41 through the second discharge channel 8. The inclined guide arc surfaces 43 set on both sides of the cover plate body 41 will further guide and spread the liquid material, so that it can fully contact the bottom surface of the roller brush head 6. At the same time, the roller brush head 6 is rolled on the target area on the wall, so that the liquid material covering the surface of the roller brush head 6 is coated on the target area, thereby achieving the painting effect. The subsequent periodic squeezing and rolling operations can be performed.

[0047] Example 3

[0048] Please see Figures 11-12The bottom of the elastic brush head sleeve 1 is provided with a linkage disassembly component 7. The linkage disassembly component 7 includes a support sleeve 71. The support sleeve 71 is fixedly sleeved inside the structure at the bottom of the elastic brush head sleeve 1 and communicates with the internal space of the annular cylinder body 31. The support sleeve 71 is fixedly nested with a first sealing ring 76 and movably sleeved with a T-shaped rod 74. One end of the T-shaped rod 74 is engaged inside the first sealing ring 76 and seals the internal space of the first sealing ring 76. A spring 75 is installed between the bottom of the T-shaped rod 74 and the bottom surface of the support sleeve 71.

[0049] The bottom of the support sleeve 71 extends to the outer bottom of the elastic brush head sleeve 1 and has an external thread. A spring 75 is fixed to the outer bottom of the T-shaped rod 74. A combined sealing cylinder 73, which is spirally locked to the outer bottom of the support sleeve 71, is snapped onto the outer top of the spring 75. The closed space formed by the T-shaped sealing cylinder 72 covers and seals the connection between the T-shaped rod 74 and the first sealing ring 76. A second sealing ring 77 is fitted on the outer top of the T-shaped sealing cylinder 72. The surface of the second sealing ring 77 is in close contact with the inner wall of the combined sealing cylinder 73. The second sealing ring 77 enhances the sealing effect of the connection between the T-shaped sealing cylinder 72 and the combined sealing cylinder 73.

[0050] When using it, considering the cleaning needs of the elastic brush head sleeve 1 and related structures after the subsequent painting work is completed, gently pry open the two sides of the top of the elastic brush head sleeve 1 to make room, then take out the roller brush head 6. After that, press the T-shaped sealing cylinder 72 so that one end of the T-shaped sealing cylinder 72 enters the interior of the annular cylinder body 31 under the snap-fit ​​guidance of the combined sealing cylinder 73 and the T-shaped sealing cylinder 72, and under the snap-fit ​​guidance of itself and the first sealing ring 76, and pushes the cover plate body 41 from bottom to top until the cover plate body 41 separates from the interior of the annular cylinder body 31. This makes room for cleaning inside the elastic brush head sleeve 1, providing convenient rinsing conditions.
