[0016] Figure 1 is an exploded view of the structure of the present utility model in one embodiment;

[0017] Figure 2 is a schematic structural view of the movable cylinder in one embodiment. Detailed Embodiments

[0018] The present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the convenience of description, only the parts related to the present utility model rather than all the structures are shown in the drawings.

[0019] As Figure 1 and Figure 2 shown, the technical solution adopted by the present utility model is that the present utility model is a self-feeding brush, which includes a handle assembly 1 and a brush barrel assembly 2. The handle assembly 1 includes a telescopic rod 3, the telescopic rod 3 includes a plurality of rod segments 4, the brush barrel assembly 2 includes an end barrel 5, a plurality of movable barrels 6 and a cover 7 arranged in sequence. The cover 7 is detachably connected to the adjacent movable barrel 6. The plurality of rod segments 4 are connected to the plurality of movable barrels 6 in a one-to-one correspondence. An annular body 8 is arranged at one end of the movable barrel 6 close to the end barrel 5. A plurality of material leakage holes 9 are arranged on the outer side of the annular body 8. The outer diameter of the annular body 8 is smaller than the outer diameter of the movable barrel 6. A relief groove adapted to the annular body 8 is arranged at one end of the movable barrel 6 far from the end barrel 5. A rotating ring 10 is sleeved outside the end barrel 5 and the movable barrel 6, and bristles are arranged on the rotating ring 10.

[0020] In the above solution, the end barrel 5 is in a cylindrical shape with one side sealed and the other side open. The movable barrel 6 is in an overall annular shape. The end barrel 5, the movable barrel 6 and the cover 7 can form a storage barrel for storing paint. The rotating ring 10 outside the end barrel 5 and the movable barrel 6 can rotate freely, and the function of rolling and painting of this brush can be realized. The telescopic rod 3 can be telescoped. Therefore, when the telescopic rod 3 extends, the plurality of movable barrels 6 can be separated from each other. In this case, the rotating ring 10 will disengage from the relief groove and expose the material leakage holes 9. Therefore, the paint can leak out through the material leakage holes 9, and the leaked paint can be stained on the bristles, providing new paint for the bristles. In this way, the self-feeding function of the brush can be realized. Using the brush barrel of the present utility model can avoid the operation of frequently dipping the brush barrel into the paint bucket again, simplify the painting operation and save time, thereby improving efficiency.

[0021] In one embodiment, the handle assembly 1 includes a handle 11 and a connecting member 12 connected to the handle 11, and the connecting member 12 is connected to the telescopic rod 3.

[0022] In one embodiment, an electric control module matched with the telescopic rod 3 is arranged on the handle 11. The electric control module includes a button 13. The connecting member 12 is provided with a hollow channel, and a wire electrically connecting the telescopic rod 3 and the electric control module is arranged in the hollow channel.

[0023] In the above solution, the electric control module is a conventional electrical component that can electrically drive the telescopic rod 3 to extend and retract.

[0024] In one embodiment, a connecting block 14 connected to the corresponding rod section 4 is disposed inside the movable cylinder 6 .

[0025] In one embodiment, the sealing cover 7 and the movable cylinder adjacent thereto are connected via threaded fitting.

[0026] In one embodiment, a cylindrical groove body 15 is provided in the middle of one side of the sealing cover 7 close to the end cylinder body 5 , and the cylindrical groove body 15 is plugged into the rod section 4 at the end section of the telescopic rod 3 .

[0027] In the above scheme, the end cylinder 5 and one end of the telescopic rod 3 can be fixed on the end of the connecting piece 12, and after the cover 7 is plugged into the cylindrical groove 15 and the telescopic rod 3, both ends of the storage barrel structure composed of the end cylinder 5, the movable cylinder 6 and the cover 7 can be supported, making the entire brush more durable and less prone to damage.

[0028] In one embodiment, a plurality of the leakage holes 9 are arranged on the annular body 8 in a circular array.

[0029] In one embodiment, both ends of the end cylinder 5 and the movable cylinder 6 are provided with limit blocks 16 matched with the corresponding rotating ring 10 .

[0030] In the above solution, the design of the limit block 16 prevents the rotating ring 10 from moving sideways and can only rotate at a limited position.

[0031] Initially, the end cylinder 5, the movable cylinder 6 and the cover 7 form a material storage barrel structure, and the multiple movable cylinders 6 are tightly connected to each other. The cover 7 can be opened and paint can be added to the material storage barrel structure. The material storage barrel structure is a cylindrical structure as a whole, and the telescopic rod 3 is located at a coaxial position of the internal central axis of the material storage barrel structure; subsequently, the telescopic rod 3 can be electrically driven to extend, and the multiple movable cylinders 6 gradually present an unfolded state, so that the leakage hole 9 is exposed, and the paint can flow out of the leakage hole 9 and can be stained on the bristles. The leakage hole 9 can be designed as a small hole with a small aperture, so that a large amount of paint will not leak out; when the bristles are stained with enough paint, the telescopic rod 3 can be controlled to shrink, so that the multiple movable cylinders 6 are tightly connected to each other again, and the end cylinder 5, the movable cylinder 6 and the cover 7 form a sealed material storage barrel structure again. Among them, when the multiple movable cylinders 6 are tightly connected to each other again, the annular body 8 can be inserted into the clearance groove and hidden.
