Description

Technical Field

[0001] This utility model relates to the field of adhesive application tools, specifically a squeezeable adhesive storage brush that is easy to clean. Background Technology

[0002] In many industries such as handicrafts, furniture manufacturing, and plumbing repair, applying adhesive is a common and important process. Currently, there are two main methods for manual adhesive application: direct drip application and brush application. For more viscous adhesives, brush application is usually preferred. However, existing conventional brushes have several problems in use.

[0003] For example, when applying glue, the brush is usually first dipped into the glue container to soak up the glue, then removed and applied to the surfaces to be bonded. Because there is initially a lot of glue on the brush bristles, the initial layer of glue is quite thick. As the glue on the brush gradually runs out, the glue layer thins, resulting in glue buildup and extremely uneven application. During the transfer of glue from the container to the surface, excess glue on the brush can also cause dripping. This not only wastes a significant amount of glue, increasing the cost of large-area application, but also makes the application area messy. Furthermore, the uneven glue layer increases glue consumption and prevents the two surfaces from making proper contact, affecting the strength of the bond.

[0004] Furthermore, existing brushes require cleaning off residual glue after application, which is inconvenient and results in a poor user experience. In summary, existing conventional brushes have significant drawbacks in glue application, including uneven application thickness, excessive glue waste, weak adhesion, and inconvenience, and urgently need improvement. Summary of the Invention

[0005] The purpose of this invention is to provide a squeezeable glue storage brush that is easy to clean. The brush does not need to be soaked in glue in a glue bucket; the glue can be squeezed from the glue bottle to allow the glue to flow onto the brush strip. Furthermore, the detachable access plate and brush strip make it easier to clean, thus solving the problems in the prior art.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: a squeezeable glue-storing and easy-to-clean brush, comprising a brush body, a detachable access plate installed at the bottom of the brush body, a brush handle installed at the top of the brush body, and a glue bottle embedded in the brush handle. The bottom surface of the brush body has several tapered plugs arranged along its length. The access plate has tapered holes that mate with the tapered plugs. Several brush strips arranged along their length are installed on the side of the access plate away from the brush body. The outlets of the tapered holes are located between adjacent brush strips. The glue outlet of the glue bottle is connected to the tapered plugs. Squeezing the glue bottle allows the glue inside to flow through the tapered plugs and tapered holes onto the brush strips. Limiting hooks are installed at both ends of the brush body along its length. When the limiting hooks are engaged with the ends of the access plate, the tapered plugs are located within the tapered holes. The glue bottle has a dispensing port at the end furthest from the brush body, and a rubber plug is fitted onto the dispensing port. Corresponding to the position of the rubber plug, a closable rear cap is installed on the brush handle. The glue bottle is made of transparent material, and a graduation mark is provided on one side of the bottle. The unit of the graduation mark is ml, and the difference between two adjacent graduation marks is 25 ml. The glue bottle has a threaded opening at one end near the brush body, serving as the glue outlet. A valve structure for adjusting the glue flow is installed between the brush body and the brush handle. This valve structure includes a partition plate with a valve opening in the center. A rubber ring is fitted onto the inner circumference of the valve opening, and a rotatable valve baffle is fitted inside the rubber ring. A rotating rod is mounted at the rotation axis of the valve baffle, and an adjusting torque block is installed at the end of the rotating rod extending out of the partition plate. The adjusting torque block is located on the outside of the brush body. An extension ring is installed on the side of the valve opening near the glue bottle, with an internal thread on its inner circumference that mates with the external thread of the glue bottle opening. The glue bottle opening is screwed onto the extension ring. A flow guide block is installed inside the brush body. The inlet at the top of the flow guide block connects to the valve opening of the partition plate. The flow guide block also contains several evenly distributed flow guide cavities connected to the inlet, each of which is connected to a conical plug. The brush strip is made of high-strength nylon or polyester chemical fiber, and the surface of the brush strip is coated with an anti-stick coating.

[0007] The positive effects of this utility model are as follows: This utility model describes a squeezeable, easy-to-clean glue-storing brush. The brush body is detachably equipped with an access plate and brush strips. A glue bottle for storing glue is installed on the brush handle. Squeezing the glue bottle allows the internal glue to flow onto the brush strips, which are evenly distributed. The corresponding conical plugs and conical holes ensure uniform glue dispersion, preventing glue buildup and improving brushing quality and construction effect, resulting in tighter adhesion and more efficient, uniform glue application. The glue bottle can be refilled and reused without replacement, improving work efficiency and reducing construction costs. Surface graduations visually indicate the amount of glue used, allowing for precise control and reducing waste. The glue bottle's outlet is threaded with a valve structure. Adjusting the torque lever controls the opening and closing of the valve baffle, thereby controlling the glue flow rate and improving both control and sealing performance. The access plate and brush strips are easy to disassemble and clean separately. The brush strips are made of a special material with an anti-stick coating, making it easy to clean residual glue, thus increasing the brush's reusability and extending its service life.

[0010] This utility model describes a compressible, easy-to-clean brush for storing adhesive, such as... Figure 1-7 As shown, it includes a brush body 1, a detachable access plate 6 installed at the bottom of the brush body 1, a brush handle 4 installed at the top of the brush body 1, and a glue bottle 9 embedded in the brush handle 4 for storing glue liquid.

[0011] The bottom surface of the brush body 1 is provided with several tapered plugs 3 arranged along the length direction. The access plate 6 is provided with tapered connecting holes 7 that cooperate with the tapered plugs 3. Several brush strips 8 arranged along the length direction are installed on the side of the access plate 6 away from the brush body 1. The outlet of the tapered connecting hole 7 is located between adjacent brush strips 8. The glue bottle 9 has a glue outlet connected to the tapered plugs 3. Squeezing the glue bottle 9 allows the glue inside to flow through the tapered plugs 3 and the tapered connecting holes 7 onto the brush strips 8.

[0012] Limiting hooks 2 are installed at both ends of the brush body 1 along its length. When the limiting hooks 2 are engaged with the end of the access plate 6, the tapered plug 3 is located in the tapered connection hole 7.

[0013] The tapered connection hole 7 on the surface of the access plate 6 matches the tapered plug 3 at the bottom of the brush body 1. This plug-in design allows the access plate 6 to connect accurately to the brush body 1, enabling quick positioning and engagement during installation and easier disassembly. Users can easily remove the access plate 6 and its brush strip 8 from the brush body 1 for separate cleaning. The limiting hook 2 also provides some support to the access plate 6, further enhancing its stability on the brush body 1. Thanks to the stable and precise connection between the access plate 6 and the brush body 1, these brush strips 8 can be distributed on the brush with uniform spacing and arrangement. The through holes on the brush strips 8 are opened between the bristles and the connecting section, allowing the glue to flow out from the semicircle next to the bristles. This limits the flow rate of the glue to a certain extent, ensuring that the glue is evenly spread on the surface of the object being brushed, avoiding situations where there is too much or too little glue in some areas. This makes the glue application smoother and more uniform. Compared with the unevenly distributed and randomly arranged glue-applying structure of the brush strips 8, this effectively improves the glue application quality, ensures the tightness and firmness of the two surfaces when they are bonded together, and improves the construction effect.

[0014] When using, connect the conical connector 7 and the conical plug 3 tightly, fix the access plate 6 to the brush body 1, and after installation, squeeze the glue bottle 9 so that the glue inside flows through the conical plug 3 and the conical connector 7 onto the brush strip 8 to perform the glue application.

[0015] Furthermore, the glue bottle 9 may have a filling port 11 at the end furthest from the brush body 1, and a rubber plug 12 is fitted onto the filling port 11. Corresponding to the position of the rubber plug 12, a closable rear end cap 5 is installed on the brush handle 4. The glue bottle 9 is made of transparent material, and a scale line 10 is provided on one side of the glue bottle 9. The remaining glue content in the glue bottle 9 can be observed through the scale line 10, so as to replenish it in time.

[0016] When using the product, the operator determines the amount of glue needed based on the workload, squeezes the glue bottle 9 to squeeze out the glue, and keeps their eyes level with the scale line 10 on one side of the glue bottle 9 to control the amount of glue squeezed out. After the glue in the bottle is used up, the rear cap 5 can be opened, the rubber plug 12 can be pulled out, and glue can be injected through the glue inlet 11.

[0017] The glue bottle 9 is embedded in the brush handle 4, combining the glue bottle 9 with the brush handle 4. This avoids the situation in the prior art where the glue bottle 9 is connected to the end of the handle, resulting in an excessively long brush handle that makes it difficult for the operator to exert force. Furthermore, when the glue is used up, it can be directly injected from the rear to replenish the glue, eliminating the need to repeatedly replace the glue bottle 9. This provides a continuous and stable supply of glue during the glue application process, making it simpler, faster, more suitable for actual use scenarios, and improving work efficiency.

[0018] The graduation line 10 provides operators with an intuitive and visual representation of the glue volume, facilitating precise control of the glue extrusion amount, avoiding glue waste, and ensuring consistent glue application results. This significantly improves the scientific and rational use of glue, helping to reduce costs and guarantee application quality. The glue filling port 11 provides a dedicated inlet channel for replenishing glue into the glue bottle 9. When the glue in the glue bottle 9 is used up or insufficient, it can be easily replenished without complicated operations or special tools, greatly improving the convenience of the glue replenishment process. Compared to some glue storage containers with unreasonable opening designs and difficulties in replenishing glue, this is more in line with actual usage scenarios, facilitating daily maintenance and use. The rubber plug 12, with its excellent elasticity and sealing performance, can tightly seal the glue filling port 11, effectively preventing glue leakage and evaporation during storage, avoiding glue waste and reducing usage costs.

[0019] Furthermore, the unit of the scale lines 10 is ml, and the difference between two adjacent scale lines 10 is 25 ml. This clear and regular scale setting facilitates quick operational decisions by the user, improving the efficiency of glue application and making the entire glue application process more convenient and smooth. The 25 ml interval between every two scale lines 10 avoids both overly dense scales that are difficult to distinguish and overly large spacing that prevents precise dosage control, greatly enhancing the accuracy of glue dosage control. During use, by observing the changes in glue remaining amount displayed on the scale lines 10, the approximate range of glue remaining can be intuitively and accurately determined, allowing for replenishment when glue is insufficient.

[0020] Furthermore, the glue bottle 9 has an externally threaded opening at one end near the brush body 1, which serves as the glue outlet. A valve structure for adjusting the glue flow rate is installed between the brush body 1 and the brush handle 4. The valve structure includes a partition plate 13 with a valve port 14 in the middle. A rubber ring 15 is fitted on the inner circumferential surface of the valve port 14. A rotatable valve baffle 16 is fitted inside the rubber ring 15. A rotating rod 17 is installed at the rotation axis of the valve baffle 16. An adjusting torque block 18 is installed at one end of the rotating rod 17 that extends out of the partition plate 13. The adjusting torque block 18 is located on the outside of the brush body 1. An extension ring 19 is installed on the side of the valve port 14 near the glue bottle 9. The inner circumferential surface of the extension ring 19 has an internal thread that mates with the external thread of the glue bottle 9's opening. The glue bottle 9's opening is screwed onto the extension ring 19. By rotating the adjusting lever 18, the rotation angle position of the valve baffle 16 at the valve port 14 can be adjusted, thereby adjusting the flow area of ​​the valve port 14 and thus controlling the flow rate of the glue.

[0021] The valve 14, in conjunction with components such as the rubber ring 15 and the valve baffle 16, can flexibly adjust its opening degree according to actual glue application needs. This allows for precise control of the glue flow rate from the glue bottle 9 to the brush, meeting the specific glue dosage requirements in different application scenarios. It effectively avoids problems such as excessive glue flow leading to dripping waste and environmental pollution, and insufficient flow affecting the application effect. Compared to other valve structures that struggle to precisely control flow, this structure significantly improves the accuracy of glue dosage control.

[0022] A rubber ring 15 is fitted onto the surface of the valve port 14, effectively preventing glue leakage from the valve port 14, ensuring the sealing of the glue bottle 9, and avoiding glue waste. Secondly, when the valve baffle 16 rotates to adjust the flow rate, the rubber ring 15 provides resistance and sealing assistance due to its own elasticity, making the adjustment of the valve baffle 16 more stable and precise. During the rotation of the valve baffle 16, the opening and closing size of the valve port 14 can be directly controlled, enabling rapid and flexible adjustment of the glue flow rate. Users can easily control the valve baffle 16 by manually rotating the adjusting knob 18, thereby adjusting the glue flow rate. The operation is intuitive and simple, requiring no complex tools or special skills. The extension ring 19 ensures the firmness of the connection between the valve structure and the glue bottle 9, making them tightly connected and preventing loosening or detachment during use. This ensures the stability of the entire structure and effectively prevents glue leakage from the connection between the valve and the glue bottle 9, further guaranteeing the sealing of the entire glue storage and usage process.

[0023] When preparing to apply glue and needing to control the glue flow, rotate the adjusting knob 18 to open the valve baffle 16 and squeeze the glue bottle 9. Alternatively, adjust the opening and closing degree of the valve baffle 16 according to the required glue flow. When enough glue has flowed out, simply smooth it with a brush, then close the valve baffle 16 and the rubber ring 15 to prevent glue from overflowing.

[0024] Furthermore, a flow guide block 20 is installed inside the brush body 1. The inlet at the top of the flow guide block 20 is connected to the valve port 14 of the partition plate 13. Several evenly distributed flow guide cavities 21, connected to the inlet, are also provided inside the flow guide block 20. Each flow guide cavity 21 is connected to each conical plug 3. After the adhesive enters the flow guide block 20, the flow guide cavities 21 distribute the adhesive relatively evenly, ensuring that the amount of adhesive flowing to the brush body 1 is as uniform as possible.

[0025] The guide block 20 allows the glue flowing out of the valve structure to smoothly enter the conical plug 3, creating an orderly channel for the glue to flow from the glue storage part to the brush body 1. This avoids the glue flowing out in a disorderly manner and scattering everywhere, laying the foundation for uniformly guiding the glue to the brush body 1 in the future. It also avoids storing too much glue inside the hollow brush body 1, which would cause waste. The flow channels 21 prevent the glue from concentrating in one place during the application process. Instead, the glue is evenly distributed into each flow channel 21, ensuring a relatively uniform amount of glue flowing to the brush body 1. This effectively avoids problems such as uneven glue distribution, localized glue buildup, or insufficient glue in some areas affecting the bonding effect. Compared to structures without dedicated and evenly distributed flow channels 21 that cannot achieve uniform glue dispersion, this design significantly improves the uniformity and quality of glue application. The outlets of several flow channels 21 are matched with the through holes at the bottom of the brush body 1. This precise design ensures that the evenly dispersed glue can flow accurately into the brush body 1 and reach the brush strip 8, guaranteeing that the glue is supplied to the brush strip 8 in the appropriate amount and at the appropriate location for application.

[0026] Furthermore, the brush strip 8 is made of high-strength nylon or polyester chemical fiber, and its surface is coated with an anti-stick coating. High-strength nylon or polyester chemical fiber materials have high strength and good toughness, effectively resisting external forces and are not prone to breakage or deformation. They can maintain a good shape and adhesive application function for a long time. Compared to brush strips made of ordinary materials that are easily damaged, this greatly extends the lifespan of the brush and reduces the cost of frequently replacing the brush strip 8 or the entire brush. The anti-stick coating significantly reduces the adhesion of adhesive to the brush strip 8, allowing the adhesive to distribute more smoothly on its surface during application without excessive accumulation or sticking. This helps to achieve uniform application of adhesive to the object being brushed, avoiding uneven application and glue buildup caused by excessive adhesion to the brush strip 8, thus improving the quality and effect of adhesive application. Furthermore, after application, the anti-stick coating makes it easier to clean any remaining adhesive from the brush strip, improving the brush's maintainability and reusability. When using the brush, take advantage of the excellent properties of the brush strip 8 itself and clean the brush strip 8 quickly after applying the glue to create conditions for repeated use in the future.

[0027] The operation of this embodiment is as follows: Rotate the adjusting knob 18 to control the opening and closing of the valve baffle 16, squeeze the glue bottle 9 to squeeze out the glue, the glue flows through the guide block 20 and the guide cavity 21, passes through the through hole of the conical plug 3, and reaches the upper end of the brush strip 8 to perform uniform glue application. Observe the scale line 10 on the surface of the glue bottle 9. If the glue is insufficient, open the rear cover 5, pull out the rubber plug 12, inject glue from the glue filling port 11, and continue the operation. When there is enough glue, close the valve baffle 16, hold the brush handle 4 and brush the glue evenly.
