[0021] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention is described below using specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0022] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0023] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] Example: Figures 1 to 6 As shown, a paint roller brush mainly consists of a material guide tube 1, a bracket 2, and a roller 3. The material guide tube 1 is connected to the paint bucket. The material guide tube 1 is partially located inside the roller 3. The material guide tube 1 located inside the roller 3 is provided with a feed hole 1-1. The bracket 2 is installed outside the material guide tube 1 to provide support for the roller 3. A material chamber 4 is formed between the inner wall of the roller 3 and the outer wall of the material guide tube 1. The paint in the material guide tube 1 enters the material chamber 4 through the feed hole 1-1. The paint in the material chamber 4 then flows to the surface of the roller 3. The brushing action is achieved by rolling the roller 3, and there is no need to manually immerse the roller in the paint bucket. To prevent paint from leaking from the opening of the material chamber 4, a cap 5 is provided at both ends of the opening of the material chamber 4 in this embodiment. The structure of the paint bucket in this embodiment is similar to that of a backpack sprayer, that is, the paint bucket is equipped with a manual pressure pump, and the piston in the pump body moves up and down by manual pressure or rocker operation. When the piston moves upward, a vacuum is formed in the pump body and the coating liquid is sucked into the pump body; when the piston moves downward, the coating liquid is pressurized and enters the above-mentioned material containing cavity 4 through the above-mentioned material guide pipe 1.

[0025] The material guide tube 1 may be a flexible, wear-resistant, corrosion-resistant, and high-temperature-resistant tube. It typically consists of an inner metal or fiber-reinforced structure and an outer plastic or rubber layer. It can be bent freely into various angles and exhibits excellent flexibility. The buckles between the sections provide a certain degree of tensile strength to prevent damage to the hose, thereby extending the service life of the material guide tube 1 and reducing operating costs. The material guide tube 1 can be quickly connected to the paint bucket using a quick connector or clamp, reducing operational difficulty.

[0026] The material guide tube 1 in this embodiment is bent and formed with a hand-held portion 1-2. The design of the hand-held portion 1-2 allows the operator to easily hold the material guide tube 1, especially when the material guide tube 1 needs to be moved, the direction needs to be adjusted, or the paint flow needs to be controlled. The hand-held portion 1-2 provides a stable gripping point. In order to reduce the fatigue of the operator's hands, a handle 6 is provided on the outer cover of the hand-held portion 1-2 in this embodiment. The setting of the handle 6 can increase the friction and comfort of the hand-held portion 1-2. The handle 6 is made of non-slip materials such as rubber, so that it can better fit the palm of the hand and provide a more comfortable gripping experience. The handle 6 is replaceable. When the handle 6 is worn or otherwise affects the user experience, the handle 6 can be removed and replaced without replacing the entire roller brush, thereby improving the user experience.

[0027] The support 2 in the embodiment includes a main sleeving part 2-1 and a supporting part 2-2. The main sleeving part 2-1 is used to be sleeved on the material guide pipe 1 and can firmly fix the material guide pipe 1 on the support 2 to prevent the material guide pipe 1 from shaking or moving during construction. The fixing mode can ensure that the material guide pipe 1 remains stable during paint conveying and avoids paint leakage or uneven spraying caused by external force. The supporting part 2-2 is multiple, and the multiple supporting parts 2-2 are equidistantly distributed along the circumference of the main sleeving part 2-1. The multiple supporting parts 2-2 can disperse the weight of the material guide pipe 1 and the pressure generated during construction to multiple points, thereby reducing the burden of a single supporting point, improving the stability and service life of the entire roller brush, and ensuring the brushing effect of the roller brush. In order to ensure the structural strength and service life of the support 2 itself, the main sleeving part 2-1 and the supporting part 2-2 are integrally formed.

[0028] In order to prevent the support 2 from moving and other phenomena during installation and use, a limiting part 1-3 for installing the main sleeving part 2-1 is formed on the outer wall of the material guide pipe 1. The outer diameter of the limiting part 1-3 is smaller than the outer diameter of the material guide pipe 1. The main sleeving part 2-1 is installed at the limiting part 1-3 to support the roller 3 and can rotate with the roller 3. Similarly, in order to reduce the burden of a single support 2, multiple supports 2 are provided along the length direction of the roller 3.

[0029] The roller 3 has a discharging groove 3-1 on the surface. The roller 3 can be made of hard material, and short hair or cloth material is attached to the surface. The paint in the material cavity 4 can penetrate into the short hair of the roller through the discharging groove 3-1 to brush the wall surface that needs to be brushed. During the entire process, the paint penetrates from the inside to the outside, which can greatly reduce the probability of material dripping and other environmental impacts caused by the roller brush and material waste, and improve the user experience.

[0030] In order to reduce the assembly difficulty, the support 2 and the roller 3 are integrally formed. During assembly, only the material guide pipe 1 with the feeding hole 1-1 needs to be installed in the material cavity 4.

[0031] The paint roller brush in the embodiment can be applied to a brushing device that can automatically feed paint, but is not limited thereto. The brushing device also includes a paint bucket, and the paint bucket is in communication with the material guide pipe 1.

[0032] The paint roller brush is characterized in that: the paint roller brush is provided with a material guide pipe 1, a support 2 and a roller 3, a material containing cavity 4 capable of containing paint is formed between the material guide pipe 1 and the roller 3, paint in the material guide pipe 1 enters the material containing cavity 4 through a feeding hole 1-1, the paint in the material containing cavity 4 flows to the surface of the roller 3, and the paint brushing action is realized by rolling the roller 3, the roller does not need to be manually soaked into a paint bucket, the paint waste is avoided, the painting efficiency is improved, the use experience is improved, and the above-mentioned paint roller brush is conducive to the promotion and application in the market.
