Technical Field

[0001] This utility model relates to the technical field of coating devices for liquids or gels, specifically a liquid-control bottle brush that can extend its overall length as required. Background Technology

[0002] Coating processes typically utilize roller brushes. Current roller brushes generally consist of a reservoir and a roller brush connected to the reservoir's outlet. However, because this structure uses a fixed connection between the reservoir and the roller brush, it's impossible to extend the distance between them as needed. For example, patent application number 202320561199.X discloses a material-storage type paint roller brush. Consequently, users need to use methods such as standing on tiptoe to paint certain distances, or they need to bend over or squat excessively when painting relatively low areas, thus affecting the comfort and convenience of operation. Therefore, existing roller brushes cannot extend or change their length to meet different operational needs. Utility Model Content

[0022] Example 1

[0023] Please see Figures 1-7 As shown in the figure, this embodiment discloses a liquid-control bottle brush that can extend its overall length as required, including a liquid storage cylinder 1 and a roller brush 2. The roller brush 2 is hinged to a roller brush base 18. The liquid storage cylinder 1 is provided with a liquid outlet 3. The outer side of the liquid outlet 3 is provided with an external threaded portion 4. The top of the roller brush base 18 is provided with an end cap 6 with an internal threaded opening 5. The center of the end cap 6 is provided with a liquid delivery through hole 7 communicating with the surface of the roller brush 2. In order to improve the liquid delivery speed, the liquid delivery through hole 7 is a waist-shaped hole. An extension tube 8 is detachably connected between the external threaded portion 4 and the internal threaded opening 5 on the inner wall of the end cap 6. One end of the extension tube 8 is provided with an internal threaded opening 9 that is threaded to the external threaded portion 4, and the other end of the extension tube 8 is provided with an external threaded portion 10 that is threaded to the internal threaded opening 5. When the extension tube 8 is detached, the external threaded portion 4 can be threadedly screwed to the internal threaded opening 5 on the inner wall of the end cap 6.

[0024] Preferably, to improve the sealing during liquid delivery and prevent leakage, a U-shaped flexible inner plug 11 is fitted over the liquid outlet 3. The flexible inner plug 11 is made of thermoplastic elastomer (TPE) material. A boss 12 extending upwards is provided at the center of the flexible inner plug 11. The center of the boss 12 serves as the liquid outlet 13, communicating with the infusion through-hole 7. An annular boss 14 extending upwards is provided at the center of the end cap 6. The infusion through-hole 7 is located within the central through-hole of the annular boss 14. A liquid guiding inner tube 15 is inserted between the annular boss 14 and the boss 12, and an extension tube 8 is sleeved around the liquid guiding inner tube 15. To improve the locking effect, one end of the liquid guiding inner tube 15 is inserted into the annular boss 14. The inner wall is provided with a limiting platform 141 that mates with the end face of the liquid guiding inner tube 15. The other end of the liquid guiding inner tube 15 is sleeved on the outside of the boss 12 and contacts the outer wall of the boss 12. Preferably, this further avoids leakage at the outlet. The outer side of the soft inner plug 11 is provided with an extension platform 17 that abuts against the end face of the outlet 3. By adding the extension platform 17, this structure ensures that the extension platform 17 abuts against the end face of the outlet 3 when the soft inner plug 11 is installed at the outlet 3, which further avoids leakage at the outlet and improves the sealing performance. In this embodiment, the liquid guiding inner tube 15 is made of polypropylene (ABS), and both ends can be precisely engaged and connected with the boss 12 inside the soft inner plug 11 and the annular boss 14 on the end cap 6 to further prevent liquid leakage.

[0025] Preferably, to improve the overall strength of the inner liquid guiding tube 15, one or more reinforcing ribs 16 are arranged in a ring around the outer side of the inner liquid guiding tube 15, and the outer wall of the reinforcing rib 16 abuts against the inside of the extension tube 8. By adding the reinforcing rib 16, and the reinforcing rib 16 having an arc-shaped outer surface, damage to the inner wall of the extension tube 8 is avoided when it is installed inside the extension tube 8. At the same time, the overall strength and hardness of the inner liquid guiding tube 15 are improved, preventing deformation of the inner liquid guiding tube 15 when conveying liquid or gel, which would affect the infusion effect. Moreover, the added inner liquid guiding tube 15 achieves precise liquid guidance, effectively preventing liquid from overflowing from the outer side of the inner liquid guiding tube 15, ensuring liquid sealing, and improving the overall stability and safety of the product.

[0026] This structure incorporates a detachable extension tube 8 between the liquid storage cylinder 1 and the roller brush 2, allowing for the extension of the entire brush length to meet the operational needs of different users and ensure operational comfort and convenience. When applying coating to lower sections of the cloth, there is no need for excessive bending or squatting, making operation easier for users. Furthermore, the extension tube 8 includes a liquid guiding inner tube 15, with one end of the inner tube 15 engaging with the protrusion 12 of the soft inner plug 11 covering the liquid outlet 3, and the other end engaging with the annular protrusion 14 at the center of the end cap 6. This achieves a precise connection between the liquid storage cylinder 1 and the bottle opening on the roller brush 2, ensuring a high degree of seal at the connection and further preventing liquid leakage.

[0027] 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.
