[0026] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments. Example

[0029] Reference Figures 1-2This is the first embodiment of the present invention. This embodiment provides a paint application device that is easy to assemble and disassemble, including a roller brush assembly 100 and a container bottle 200. The container bottle 200 and the roller brush assembly 100 are connected by threads or snaps for sealing. Through the roller brush assembly 100 and the container bottle 200, an integrated painting tool for feeding and painting is provided. At the same time, the roller brush assembly 100 can easily replace the brush head according to different usage scenarios and the roughness of the wall surface to be painted. It can also be replaced in time when the brush head becomes contaminated, which improves construction efficiency and saves construction costs. Manufacturers can also adapt different types of paint and match different brush heads after one mold is made.

[0030] Specifically, the roller brush assembly 100 includes a roller brush head 101, a discharge part 102, a locking part 103, and a protective shell 104. The discharge part 102 is movably connected to the protective shell 104 for uniform coating. The roller brush head 101 is connected to the protective shell 104 through the locking part 103, so that it can roll and rotate while also engaging with the protective shell 104.

[0031] When using the product, the worker holds the container 200 firmly and presses and pushes the roller brush head 101 against the wall while applying the paint. At the same time, the worker squeezes the container 200 to expel the paint. The dispensing part 102 can achieve uniform dispensing when the roller brush head 101 is installed. When the roller brush head 101 becomes contaminated, or when different textures or wall surfaces are required, the worker operates the locking part 103 to remove the roller brush head 101 and replace it with a suitable brush head. By pressing, the roller brush head is connected to the locking part 103 and the protective shell 104, and the worker can continue the application process. Example

[0032] Reference Figures 1 to 7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0033] Furthermore, the locking member 103 includes a first connecting shaft 103a, a second connecting shaft 103b, and a locking shaft 103c. The locking shaft 103c is fixed to the outer wall of the protective housing 104. One end of the second connecting shaft 103b passes through the locking shaft 103c and is rotatably connected to the first connecting shaft 103a. The free end of the first connecting shaft 103a is movably connected to the roller 101a on the brush head 101. The rotation of the brush head 101 drives the roller 101a to be rotatably connected to the first connecting shaft 103a. The first connecting shaft 103a and the second connecting shaft 103b are fastened together without disengaging and are rotatably connected, which reduces the friction caused by the rolling of the brush head 101.

[0034] Preferably, when applying paint, considering that the paint may cure in the air, the roller brush head 101 may encounter rotational resistance after being immersed in the paint between the first connecting shaft 103a and the first connecting shaft 103a and the second connecting shaft 103b. The double rotational connection allows the device to continue rotating in the other place when the paint curing resistance is encountered in one place, thereby maximizing the number of times the device can be used. As shown in the figure, the connection end of the first connecting shaft 103a and the second connecting shaft 103b has less contact with the paint in the inner cavity of the second connecting shaft 103b and is less affected by the paint curing resistance.

[0035] Furthermore, the locking component 103 also includes a compression spring 103d, which is disposed in the inner cavity of the locking shaft 103c and connects the second connecting shaft 103b and the locking shaft 103c. The free end of the second connecting shaft 103b is provided with a lifting protrusion 103b-1. When the brush head needs to be replaced, the lifting protrusion 103b-1 is pulled, which drives the second connecting shaft 103b and the first connecting shaft 103a to disengage from the roller 101a. At this time, the compression spring 103d is compressed. After the brush head 101 to be replaced is removed, the lifting protrusion 103b-1 is released, and the compression spring 103d returns to its original deformation.

[0036] When a new roller brush head 101 is installed, since the free end of the first connecting shaft 103a is provided with an inclined surface, when the roller 101a of the roller brush head 101 is inserted, the first connecting shaft 103a is squeezed and compressed, the second connecting shaft 103b and the compression spring 103d move to both sides, and after the connection between the roller 101a and the first connecting shaft 103a is completed, the deformation is restored, and the installation is completed.

[0037] By setting the locking component 103, the roller brush head 101 can be easily disassembled and assembled. The double locking structure also avoids the resistance caused by the curing of the coating, thus reducing the need for the roller brush to be laborious or to replace the roller brush head 101, improving construction efficiency and saving costs. Example

[0038] Reference Figures 1 to 7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0039] In some embodiments, the discharge component 102 includes a movable frame 102a and a discharge pipe 102b. The discharge pipe 102b is integrally formed and fixedly connected to the movable frame 102a. The discharge pipe 102b passes through the discharge port 104a provided on the protective shell 104 and extends into the container 200. The end of the discharge pipe 102b is provided with a discharge channel 102b-1. The discharge channel 102b-1 passes through the movable frame 102a to the side near the roller brush head 101, so that the paint can come into contact with the roller brush head 101 after passing through the discharge channel 102b-1 from the container 200.

[0040] In some embodiments, the discharge component 102 further includes a push rod 102c, one end of which is fixedly connected to the inner wall of the protective housing 104, and the other end of which passes through the crossbar 102a-1 on the movable frame 102a. A limit ring 102c-1 is provided at the free end of the push rod 102c, so that the movable frame 102a cannot be detached from the protective housing 104. The discharge component 102 also includes a lifting spring 102d, one end of which is connected to the inner wall of the protective housing 104, and the other end of which is connected to the crossbar 102a-1.

[0041] When the roller brush head 101 is installed on the movable frame 102, the movable frame 102 is under stress, the crossbar 102a-1 compresses the lifting spring 102d, and the discharge pipe 102b extends out of the discharge port 104a. At this time, the paint can be squeezed out. When the roller brush head 101 needs to be replaced, the roller brush head 101 leaves the movable frame 102a, the lifting spring 102d loses its force and returns to its original deformation, lifting the crossbar 102a-1. This causes the movable frame 102a to drive the discharge pipe 102b to retract into the discharge port 104a, and the paint cannot be squeezed out. This avoids the paint from accidentally flowing out when the roller brush head 101 is replaced, causing waste and environmental pollution during construction.

[0042] It should be noted that the diameter of the discharge pipe 102b matches the inner diameter of the discharge port 104a, so that the coating can achieve basic sealing without the action of extrusion pressure.

[0043] It should be noted that the roller 101a fits into the limiting groove 102a-2 provided on the movable frame 102a and is movably connected. When the roller 101a rotates, it rubs against the inner groove of the limiting groove 102a-2, and the force on the lifting spring 102d is also transmitted through the limiting groove 102a-2.

[0044] In summary, the interaction between the locking component 103 and the discharging component 102 enables a painting device that integrates material supply and brushing. This device allows for easy disassembly and replacement of brush heads when encountering different construction walls, paint types, and construction environments, while also preventing accidental paint spillage during replacement that could contaminate the construction site and cause waste.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the utility model's technical solution, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
