Description

Technical Field

[0001] This utility model relates to the technical field of coating devices for liquids or gels, specifically a liquid-control type bottle brush integrated coating device. Background Technology

[0002] Coating processes typically utilize roller brushes. Current roller brushes generally consist of a brush rod and a roller brush that is fixedly connected to the brush rod. Existing roller brushes of this type have the following problems:

[0003] 1. The scraper on the roller brush is fixedly connected to the side of the roller brush. As the usage time increases, the scraper will age and affect the effectiveness of the brush in removing excess paint.

[0004] 2. The length of the roller brush cannot be shortened or extended as required, resulting in poor applicability and difficulty in packaging;

[0005] 3. During the use of a roller brush, liquid or gel-based paint needs to be applied to the roller brush before it can be used. After a period of use, new paint needs to be applied to the roller brush before it can be used again. This requires a separate paint storage container, and the opening of the paint storage container must be large enough to wet the entire roller brush. This operation method makes it easy for excess paint to drip onto the ground when the roller brush is lifted, resulting in the need for cleaning up the site later. It is inconvenient to operate. Moreover, the repeated wetting of the roller brush can easily cause the paint in the paint storage container to become contaminated with dust. When the roller brush is contaminated with paint, it can also easily contaminate the fabric, leading to an increased rate of fabric scrap.

[0006] In summary, the current type of roller brush still has the aforementioned problems and needs improvement. Utility Model Content

[0007] The purpose of this invention is to provide a liquid-controlled bottle brush integrated coating device to solve the problems mentioned in the background art, such as the brush strips not being detachable, the brush length not being able to be shortened or extended as required, and the need for repeated wetting of the coating by the roller brush, which easily leads to the contamination of the coating and ultimately the fabric.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a liquid-control type bottle brush integrated coating device, comprising a roller brush body, a lifting rod assembly, and a flexible bottle for storing liquids or gel-like substances. The roller brush body includes a roller support and a roller brush body hinged below the roller support. An end cap is provided above the roller support, and the end cap has an internal thread. A limiting ring and a drain port that penetrates the roller support and communicates with the side of the roller brush body are provided inside the end cap. The drain port is located in the central through hole of the limiting ring. The lifting rod assembly includes an extended outer tube and an extended inner tube sleeved inside the extended outer tube. One end of the extended outer tube has an external thread, and the other end of the extended outer tube has an internal thread. An opening is provided on the flexible bottle body. The roller brush body is equipped with an external thread that connects to either internal thread one or internal thread two. A brush strip is detachably inserted at the front of the roller brush body. A soft inner plug is covered inside the opening. A limiting ring two protrudes outward at the center of the soft inner plug. The center of the limiting ring two is a through hole structure. A soft liquid control valve is inserted into the through hole of the limiting ring two. The center of the soft liquid control valve is a cross-shaped liquid outlet that communicates with the inside of the soft bottle. The cross-shaped liquid outlet is initially closed. When the soft bottle is squeezed, the cross-shaped liquid outlet opens to form a cross opening. When external thread one is screwed into internal thread two, external thread two on the extended outer tube is screwed into internal thread one. At the same time, one end of the extended inner tube is sleeved on the outside of the limiting ring two, and the other end of the extended inner tube is locked on the inside of the limiting ring one.

[0009] Preferably, in order to improve the overall rigidity of the extension rod, one or more arc-shaped reinforcing ribs are provided on the outer side of the inner extension tube, and the outer end face of the arc-shaped reinforcing ribs abuts against the inner wall of the outer extension tube.

[0010] Preferably, for ease of disassembly, an L-shaped mounting groove with notches on both sides is provided at the front of the roller support below the roller support. The L-shaped mounting groove extends along the length of the roller support, and the brush strip is inserted into the L-shaped mounting groove, with part of the brush strip protruding from the front end of the L-shaped mounting groove.

[0011] Preferably, to facilitate quick disassembly of the roller brush body later, a hinged through hole is provided on both sides below the roller support. The roller brush body includes a roller and brush bristles disposed outside the roller. Side covers are provided on both sides of the roller. Limiting protrusions that insert into the hinged through holes are provided on the outer side of the side covers. An waist-shaped guide ring is also provided inside the roller support below the drain port. The lower opening of the waist-shaped guide ring is aligned with the side of the brush bristles.

[0012] Preferably, a transparent viewing window is provided on both the front and back of the flexible bottle to facilitate viewing the volume of the internal liquid.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: Compared with the prior art, which requires the entire roller to be immersed in a large paint storage cylinder, this structure is more convenient to operate. Moreover, when squeezing out the liquid, it is less likely to cause excess liquid to fall to the ground. In addition, the overall structure is lighter and smaller in size after disassembly, making it easier to package and carry. The overall operating efficiency is improved by more than 60%. At the same time, when the paint is used, it is squeezed out, and the remaining paint will not be contaminated with dust. Therefore, the paint applied to the cloth is cleaner and will not contaminate the paint. Furthermore, the small bottle design enables more usage scenarios. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figures 1-8 As shown in this embodiment, a liquid-control type bottle brush integrated coating device includes a roller brush body 1, a lifting rod assembly 2, and a flexible bottle 3 for storing liquids or gel-like substances. To facilitate viewing the internal liquid volume, a transparent observation window 12 is provided on both the front and back of the flexible bottle 3. The addition of the transparent observation window 12 allows for easy viewing of the internal liquid volume of the flexible bottle 3, enabling timely replenishment of the liquid inside. The roller brush body 1 includes a roller support 101 and a roller brush body 1 hinged below the roller support 101. 02. An end cap 4 is provided above the roller support 101. The end cap 4 has an internal thread 401 on its inner side. The end cap 4 has a limiting ring 403 inside and a drain port 402 that penetrates the roller support 101 and communicates with the side of the roller brush body 102. The drain port 402 is located in the central through hole of the limiting ring 403. The lifting rod assembly 2 includes an extension outer tube 201 and an extension inner tube 202 sleeved in the extension outer tube 201. One end of the extension outer tube 201 has an external thread 204. The other end of tube 201 is provided with internal thread 203. The flexible bottle body 3 is provided with an opening 301. An external thread 302 is provided at the opening 301, which is threaded to either internal thread 401 or internal thread 203. A brush strip 5 is detachably inserted into the front of the roller brush body 1. A flexible inner plug 6 is fitted inside the opening 301. A protruding limiting ring 7 is provided at the center of the flexible inner plug 6. The limiting ring 7 has a through hole at its center. A flexible liquid control valve 8 is inserted into the through hole of the limiting ring 7. The flexible liquid control valve 8 has a cross-shaped liquid outlet 9 at its center, which communicates with the interior of the flexible bottle 3. The cross-shaped liquid outlet 9 is initially closed. When the flexible bottle 3 is squeezed, the cross-shaped liquid outlet 9 opens to form a cross opening 301. When the external thread 302 is screwed into the internal thread 203, the external thread 204 on the extension tube 201 is screwed into the internal thread 401. At the same time, one end of the extension tube 202 is fitted onto the outside of the limiting ring 7, and the other end of the extension tube 202 is locked into the inside of the limiting ring 403.

[0026] Preferably, in order to improve the overall rigidity of the extension rod, one or more arc-shaped reinforcing ribs 205 are provided on the outer side of the inner extension tube 202. The outer end face of the arc-shaped reinforcing rib 205 abuts against the inner wall of the outer extension tube 201. By adding the arc-shaped reinforcing ribs 205, the rigidity of the overall extension rod is further improved, and its deformation is prevented from affecting the transport of liquid.

[0027] Preferably, to facilitate disassembly later, an L-shaped mounting groove 10 with notches on both sides is provided on the front side below the roller support 101. The L-shaped mounting groove 10 extends along the length of the roller support 101. The brush strip 5 is inserted into the L-shaped mounting groove 10, and part of the brush strip 5 is exposed at the front end of the L-shaped mounting groove 10. During installation, the brush strip 5 is inserted into the L-shaped mounting groove 10 through the notch on the side, which facilitates disassembly and replacement of the brush strip 5 later.

[0028] Preferably, to facilitate quick disassembly of the roller brush body 102, a hinged through hole 11 is provided on both sides below the roller support 101. The roller brush body 102 includes a roller 1021 and brush bristles 1022 disposed outside the roller 1021. Side covers 1023 are provided on both sides of the roller 1021, and limiting protrusions 1024 that insert into the hinged through holes 11 are provided on the outer side of the side covers 1023. An waist-shaped guide ring 1025 is also provided inside the roller support 101 below, located on the outer periphery of the drain port 402. The lower opening 301 of the waist-shaped guide ring 1025 is aligned with the side of the brush bristles 1022. The above structural arrangement achieves the following: The lower opening of the waist-shaped guide ring 1025 directly engages with the surface of the brush bristles 1022, allowing the liquid to flow evenly onto the surface of the brush bristles 1022 and ensuring uniform coating distribution. Furthermore, the two ends of the roller 1021 are detachably engaged with the hinged through-hole 11 via the side cover 1023. Later, the roller 1021 can be quickly disassembled by pulling outward from one side of the roller support 101. Once the roller 1021 is disassembled, the waist-shaped guide ring 1025 is directly exposed, facilitating the later cleaning of the waist-shaped guide ring 1025 and the drain port 402. This avoids the problem of the waist-shaped guide ring 1025 and the drain port 402 not being cleaned for a long time, which could lead to blockage of the discharge port and ultimately affect the discharge rate.

[0029] In this structure, the flexible bottle 3 is made of high-elasticity polyethylene (PE). Stable pressure is generated through extrusion, allowing liquid or gel to be squeezed out from the cross-shaped outlet 9 and enter the drain outlet 402, ultimately reaching the surface of the brush bristles 1022. Compared to existing technologies where the entire roller needs to be immersed in a large paint storage cylinder, this structure is more convenient to operate. Moreover, when squeezing out liquid, it is less likely to cause excess liquid to fall to the ground. The overall structure is also lighter and smaller after disassembly, making it easier to package and carry. Overall, the operating efficiency is improved by more than 60%. At the same time, when using paint, the remaining paint will not be contaminated with dust due to the squeezing out process, resulting in cleaner paint applied to the fabric and preventing paint contamination. Furthermore, the small bottle design enables more usage scenarios.

[0030] Furthermore, the soft inner plug 6 is made of thermoplastic elastomer (TPE), and a soft liquid control valve 8 is set in the center of the soft inner plug 6. When not in use, the cross-shaped liquid outlet 9 will not leak, which can replace the problem of leakage caused by the traditional aluminum foil sealing of existing bottle mouths. This structure also showed no leakage during drop test. The soft liquid control valve 8 is made of medical grade silicone, and the cross opening 301 has a built-in cross reinforcing rib structure. It opens when the pressure exceeds 3.5N and closes quickly after the pressure is released, without leakage.

[0031] Furthermore, this structure incorporates an extension rod assembly 2, which includes an outer extension tube 201 and an inner extension tube 202 fitted inside the outer extension tube 201. The inner extension tube 202 is made of high-strength polypropylene (PP) or ABS material, enhancing its long-term durability. One end of the inner extension tube 202 is fitted onto the outside of the limiting ring 7, while the other end is secured to the inside of the limiting ring 403, further preventing liquid leakage. Simultaneously, the channel design of the waist-shaped guide ring 1025 ensures uniform coating distribution. Additionally, the addition of the extension rod assembly 2 extends the overall length of the brush, ultimately optimizing the user experience. The improved posture significantly reduces user fatigue and enhances the device's flexibility. The extended inner tube 202 features a two-end plug design: one end precisely inserts into the inner hole of the limiting ring 403 of the brush head assembly, and the other end inserts into the inner side of the limiting ring 7 of the soft inner plug at the bottle mouth. This ensures precise liquid flow along the extended inner tube, preventing overflow into the extended outer tube and significantly improving sealing and cleaning efficiency. Furthermore, the insertion structure of the extended inner tube provides a reliable guarantee for the stability and sealing of the overall structure, further enhancing the overall product performance. Ultimately, this forms a highly efficient sealed connection structure that effectively prevents liquid leakage from the connection point during transportation and use.

[0032] Meanwhile, the brush strip 5 is made of flexible thermoplastic elastomer material, which can remove excess paint instantly, and the brush strip 5 can be disassembled or replaced later, making it convenient for users.

[0033] Meanwhile, the cross-shaped liquid outlet 9 added inside the soft inner plug 6 can further achieve precise liquid control and achieve high accuracy in liquid flow rate.

[0034] There are two ways to use this structure. The first way is to directly screw the internal thread 401 on the inner side of the end cap 4 and the external thread 302 on the opening 301 when the lifting rod assembly 2 is not used. The second way is to first unscrew the internal thread 401 and the external thread 302 when it is necessary to extend the length of the entire roller brush. Then, first, put the extension outer tube 201 on the outside of the extension inner tube 202. Then, put one end of the extension inner tube 202 on the outside of the limiting ring 7. At this time, screw the internal thread 401 and the external thread 204 together. Then, put the other end of the extension inner tube 202 on the inside of the limiting ring 403. At this time, screw the external thread 302 and the internal thread 203 together.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
