DETAILED DESCRIPTION

[0022] The technical solution of the present utility model will be further described in detail below in conjunction with specific implementation methods.

[0023] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0024] Example

[0025] A wall painting device, such as Figure 1-4 As shown, it includes a brush rod 2, one end of the brush rod 2 is integrally provided with a roller shaft 14, and a brush roller 1 is rotatably mounted on the outer side of the roller shaft 14;

[0026] The other end of the brush rod 2 is provided with a handle 17, and a spray mechanism is installed on the brush rod and the handle. One end of the spray mechanism is connected to the paint bucket 7, and the spray mechanism is used to spray the paint in the paint bucket 7 onto the brush roller 1;

[0027] The spraying mechanism includes a storage capsule 5 and a nozzle assembly. The storage capsule 5 is annular and is mounted on the outside of the handle 17. One end of the storage capsule 5 is connected to a pipe 10, on which a control valve 2 9 is provided. One end of the pipe 10 is connected to the nozzle assembly, which is mounted on the brush rod 2 through a bracket assembly. The other end of the storage capsule 5 is provided with a pipe 2 15, on which a control valve 8 is provided. One end of the pipe 2 15 is connected to a paint bucket 7.

[0028] By setting up structures such as the storage capsule 5 and the nozzle assembly, when in use, the control valve 2 9 can be opened, and the paint in the storage capsule 5 can be squeezed to enter the nozzle assembly through the pipe 10, and then sprayed onto the surface of the brush roller 1 by the nozzle assembly, which can save the time of dipping the paint and improve work efficiency.

[0029] By setting up structures such as the storage bag 5 and the paint bucket 7, when paint needs to be replenished, the control valve 1 8 is used to squeeze the storage bag 5. When the storage bag 5 is deformed due to the rebound force, the paint can be absorbed from the paint bucket 7 using the pipe 2 15, thereby improving practicality.

[0030] In order to facilitate the feeding, the control valve 1 8 and the control valve 2 9 are both one-way valves. The conduction direction of the control valve 1 8 is one-way conduction from the pipeline 2 15 to the storage capsule 5, and the conduction direction of the control valve 2 9 is one-way conduction from the storage capsule 5 to the nozzle assembly.

[0031] By setting control valve 1 8 and control valve 2 9 as one-way valves, there is no need to manually control control valve 1 8 and control valve 2 9 frequently. Based on the characteristics of the one-way valve, the deformation of the storage bag 5 can be utilized to achieve continuous supply from the paint bucket 7 to the nozzle assembly.

[0032] To supplement the paint on the brush roller 1 more evenly; as Figure 3 shown, the nozzle assembly includes: a paint spraying box 4 and a nozzle 12. The paint spraying box 4 is fixed on the bracket assembly. A side of the paint spraying box 4 is provided with evenly distributed nozzles 12. The nozzles 12 are in communication with the inside of the paint spraying box 4. One end of a first pipe 10 is connected to the paint spraying box 4;

[0033] By providing structures such as the paint spraying box 4 and the nozzles 12, after the paint enters the paint spraying box 4 based on the conveyance of the first pipe 10, it can be sprayed onto the surface of the brush roller 1 through the respective nozzles 12, improving the uniformity of material feeding.

[0034] To fix the nozzle assembly; as Figure 1 shown, the bracket assembly includes a connecting rod 13 and a fixing member 3. The nozzle assembly is fixed at one end of the connecting rod 13. The other end of the connecting rod 13 is connected and fixed to the fixing member 3. The fixing member 3 is detachably fixed to the brush rod 2.

[0035] To perform brush coating and coloring; as Figure 1 、 Figure 3 shown, a scraper 18 is provided on one side of the brush roller 1; the scraper 18 has a '丿'-shaped structure. A receiving groove 20 is provided inside the scraper 18; the scraper 18 is installed on the connecting rod 13 through an adjusting component;

[0036] By providing the scraper 18, when too much paint is sprayed, the excess paint can be scraped off from the brush roller 1, thus ensuring the brushing effect.

[0037] To improve the brushing effect; as Figure 1 、 Figure 3 shown, the adjusting component includes: an adjusting seat 19 and an adjusting rod 16. The adjusting seat 19 is fixed on an outer wall of one side of the connecting rod 13. The adjusting rod 16 is slidably connected up and down inside the connecting rod 13. The scraper 18 is fixed to the top end of the adjusting rod 16. A threaded knob 11 for fixing the scraper 18 is connected by thread to an inner wall of one side of the adjusting seat 19;

[0038] By providing structures such as the adjusting rod 16, the adjusting seat 19, and the threaded knob 11, the position of the adjusting rod 17 can be adjusted and fixed by the threaded knob 11, thereby changing the position of the scraper 18 relative to the brush roller 1, so as to achieve the purpose of adjusting the scraping force and improving the practicability.

[0039] To improve the practicability; as Figure 2 shown, a protective sleeve 6 is sleeved outside the handle 17. The protective sleeve 6 is made of a flexible material.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
