[0002] With the progress of society, the role of decoration has become increasingly prominent. It is not just a simple house decoration, but covers functions, aesthetics, protection of building structure, and improvement of quality of life. Spraying operations will be carried out during the decoration process. Paints and other coatings can form a protective film to prevent or delay the erosion of oxygen, moisture, etc. on the wall, thereby extending the service life of the building. Spraying is inseparable from the use of spraying devices. Existing spraying devices are generally composed of a coating pump, a nozzle, and a handle.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work belong to the scope of protection of the present invention.

[0021] Please refer to Figures 1-4 , this embodiment provides a technical solution: a spraying device for decoration and fitment, including a frame 1 and a drive assembly 12;

[0022] Frame 1: An outer tube 3 is movably inserted at its front end. The frame 1 provides an installation position for other components. An inner tube 4 is slidably connected inside the outer tube 3. A spray head 5 is provided at the upper end of the inner tube 4. During use, the length of the handle formed by the outer tube 3 and the inner tube 4 can be adjusted. At the lower end inside the outer tube 3, a support shaft 7 is rotatably connected. In the middle of the outer arc surface of the support shaft 7, a first synchronous pulley 8 is provided. At the upper end inside the outer tube 3, a second synchronous pulley 9 is rotatably connected. The second synchronous pulley 9 and the first synchronous pulley 8 are connected by a synchronous belt 10. The first synchronous pulley 8 drives the synchronous belt 10 to operate under the support of the second synchronous pulley 9. At the lower end of the inner tube 4, a fixed block 11 is provided. The fixed block 11 is fixedly connected to the middle of the synchronous belt 10. The synchronous belt 10 drives the inner tube 4 to move along the outer tube 3 through the fixed block 11. Thus, the inner tube 4 can automatically contract or extend. The inner tube 4 drives the spray head 5 to move, enabling uniform spraying, reducing the labor burden of the spraying personnel. At the lower end of the outer tube 3, a controller 6 is provided. The input end of the controller 6 is electrically connected to an external power source. At the lower end inside the outer tube 3, a first microswitch 15 is provided. The first microswitch 15 is arranged in cooperation with the fixed block 11. At the upper end of the outer tube 3, a second microswitch 16 is provided. The second microswitch 16 is arranged in cooperation with the upper end of the long sliding hole of the inner tube 4. The output ends of the first microswitch 15 and the second microswitch 16 are both electrically connected to the input end of the controller 6. When the fixed block 11 touches the first microswitch 15, the first microswitch 15 sends an electrical signal to the controller 6, and the controller 6 controls the motor 123 to operate. Similarly, when the upper side wall of the long sliding hole of the inner tube 4 touches the second microswitch 16, the second microswitch 16 sends an electrical signal to the controller 6, and the controller 6 controls the motor 123 to operate. Thus, the moving range of the fixed block 11 can be restricted. With the forward and reverse rotation of the motor 123, the fixed block 11 moves between the first synchronous pulley 8 and the second synchronous pulley 9. In the middle of the upper end of the frame 1, a spraying pump 2 is provided. The liquid suction pipe of the spraying pump 2 is inserted into the paint. The liquid outlet end of the spraying pump 2 is connected to the liquid inlet end of the spray head 5. The outer tube 3 drives the spray head 5 to move through the inner tube 4. The spraying pump 2 operates. The spraying pump 2 pumps out coatings such as paint and sprays them through the spray head 5. Thus, spraying operations can be carried out. The input end of the spraying pump 2 is electrically connected to the output end of the controller 6. At the lower end of the outer tube 3, a handle 13 is provided. At the lower end of the outer arc surface of the outer tube 3, symmetrically distributed handles 14 are provided. Hold the handle 13 with one hand and hold one of the handles 14 with the other hand to move the outer tube 3;

[0023] Drive assembly 12: It is used to drive the rotation of the support shaft 7. The drive assembly 12 includes a worm 121 and a worm gear 122. The worm gear 122 is arranged at the rear end of the support shaft 7. The lower end inside the outer tube 3 is rotatably connected with the worm 121. The worm 121 is meshed and connected with the worm gear 122. The drive assembly 12 further includes a motor 123. The motor 123 is arranged at the lower end of the outer tube 3. The output shaft of the motor 123 is fixedly connected with the lower end of the worm 121. The input end of the motor 123 is electrically connected to the output end of the controller 6. When the motor 123 operates, the output shaft of the motor 123 drives the worm gear 122 to rotate through the worm 121. The worm gear 122 drives the first synchronous pulley 8 to rotate through the support shaft 7.

[0024] The working principle of a spraying device for decoration and fitment provided by the present utility model is as follows: During decoration, insert the liquid suction pipe of the spraying pump 2 into the paint, take out the outer tube 3, then hold the handle 13 with one hand and hold one of the handles 14 with the other hand to move the outer tube 3. The outer tube 3 drives the nozzle 5 to move through the inner tube 4. Then, adjust the controller 6. The spraying pump 2 operates. The spraying pump 2 pumps out coatings such as paint and sprays them through the nozzle 5, and thus spraying operations can be carried out. At the same time, the controller 6 can be adjusted according to the usage requirements. The motor 123 operates. The output shaft of the motor 123 drives the worm gear 122 to rotate through the worm 121. The worm gear 122 drives the first synchronous pulley 8 to rotate through the support shaft 7. The first synchronous pulley 8 drives the synchronous belt 10 to operate under the support of the second synchronous pulley 9. The synchronous belt 10 drives the inner tube 4 to move along the outer tube 3 through the fixing block 11. Thus, the inner tube 4 can automatically contract or extend. The inner tube 4 drives the nozzle 5 to move, and uniform spraying can be carried out, reducing the labor burden of spraying personnel. When the fixing block 11 touches the first micro switch 15, the first micro switch 15 sends an electrical signal to the controller 6, and the controller 6 controls the motor 123 to operate. Similarly, when the upper side wall of the long sliding hole of the inner tube 4 touches the second micro switch 16, the second micro switch 16 sends an electrical signal to the controller 6, and the controller 6 controls the motor 123 to operate. Thus, the moving range of the fixing block 11 can be restricted. With the forward and reverse rotation of the motor 123, the fixing block 11 moves between the first synchronous pulley 8 and the second synchronous pulley 9. Similarly, during use, the combined length of the outer tube 3 and the inner tube 4 as a handle can be adjusted, and thus various decoration spraying tasks can be flexibly handled, improving work efficiency and quality.

[0025] It should be noted that the spraying pump 2, the motor 123, the controller 6, the first microswitch 15 and the second microswitch 16 disclosed in the above embodiments can all be freely configured according to the actual application scenarios. The spraying pump 2 can be a spraying pump with the model number 795, the motor 123 can be a micro DC reduction motor with the model number JGB37-520, the core chip of the controller 6 can be a single-chip microcomputer with the model number AT89S51, and both the first microswitch 15 and the second microswitch 16 can be microswitches with the model number V-103-1A4-T. The controller 6 controls the operation of the spraying pump 2, the motor 123, the first microswitch 15 and the second microswitch 16 by using the commonly used methods in the prior art.
