Description

Technical Field

[0001] This utility model relates to the field of wall decoration spraying, specifically a spraying device for interior wall decoration. Background Technology

[0002] When decorating interior walls, including the process of spraying the walls, a spraying device is needed to facilitate the spraying. The "Prefabricated Interior Wall Decoration Spraying Device" disclosed in application number "CN217299683U" represents an increasingly mature technology. This device features a structure with a rear handle, a guide tube, a front handle, and a sprayer on the extraction tube. By holding the rear handle with both hands to lift the liquid tank and using the other hand to conveniently operate the front handle to adjust the spray angle and direction of the guide tube and sprayer, the device enables convenient and labor-saving spraying operations, effectively improving its practicality and convenience. However, this spraying device still has the following drawbacks during use: While the spraying device, through its guide tube, front handle, and sprayer structure, does achieve flexible spraying, its spraying area is relatively small, and the paint cannot be blocked after spraying, leading to paint splatter. Therefore, it is necessary to provide a spraying device that can improve spraying flexibility and increase the spraying area while avoiding paint splatter. In addition, the liquid tank needs to be manually lifted when moving the spraying device, affecting ease of use and making it difficult to stir the paint, which may lead to paint sedimentation. Therefore, it is necessary to provide a spraying device that is easy to move and use while avoiding paint sedimentation. Utility Model Content

[0003] This utility model provides a spraying device for interior wall decoration, aiming to solve the problems of existing spraying devices being inconvenient to move and use, as well as the difficulties in large-area spraying and mixing.

[0004] To achieve the above objectives, this utility model provides a spraying device for interior wall decoration, including a mixing component and a spraying component;

[0005] The stirring assembly includes a movable plate, with several casters detachably mounted on the lower end of the movable plate, a storage cylinder mounted on the upper end of the movable plate, a stirring blade connected to the internal rotating wheel of the storage cylinder, a first bevel gear detachably mounted on the lower end of the stirring blade, a servo motor mounted on the upper end of the movable plate, and a second bevel gear fixedly connected to the output end of the servo motor, with the first bevel gear and the second bevel gear meshing together.
