[0024] like Figure 1-6 As shown, this utility model provides a technical solution: an indoor decoration wall drilling device that can avoid dust flying, including an electric drill 1. The electric drill 1 is equipped with a dustproof mechanism 2 to prevent dust from flying. By setting the dustproof mechanism 2, the dust generated during the drilling process of the electric drill 1 can be collected in a concentrated manner, avoiding dust splashing and polluting the environment and interfering with the drilling work. The dustproof mechanism 2 is equipped with a cleaning mechanism 3, which can clean the surface of the baffle 28 to prevent dust from the surface of the baffle 28 from flying out and polluting the surrounding environment.
[0025] The aforementioned dustproof mechanism 2 includes a dust cover 21, a rotating shaft 22, an inclined block 23, a positioning spring 24, a dust hopper 25, a handle 26, a hollow rod 27, a baffle 28, a connecting spring 29, an L-shaped rod 210, and a push rod 211. The dust cover 21 is slidably connected to the outer wall of the electric drill 1. The inner wall of the dust cover 21 is fixedly installed with a positioning spring 24. The end of the positioning spring 24 away from the dust cover 21 is fixedly installed on the outer wall of the electric drill 1, pressing the drill bit of the electric drill 1 against the wall. Then, the handle 26 is pushed to move the dust hopper 25. The dust cover 21 slides on the outer wall of the electric drill 1 and adheres to the wall surface. At the same time, the dust cover 21 stretches the positioning spring 24. During the drilling process, the dust generated by the electric drill 1 is blocked by the dust cover 21, causing the dust to concentrate inside the dust cover 21, preventing dust from splashing and polluting the environment and interfering with the drilling work. A dust hopper 25 is fixedly installed on the outer wall of the dust cover 21. A handle 26 is threaded to the bottom of the dust hopper 25. One end of the rotating shaft 22 is rotatably connected to the inner wall of the dust hopper 25, and the other end of the rotating shaft 22 passes through the dust hopper. A hollow rod 27 is fixedly installed on the 25th, and a baffle 28 is fixedly installed on the outer wall of the rotating shaft 22. The rotating shaft 22 can drive the baffle 28 to rotate, thereby allowing adjacent sets of baffles 28 to separate or fit together. The inclined block 23 is slidably connected to the inner wall of the dust cover 21. A connecting spring 29 is fixedly installed on the outer wall of the inclined block 23. The end of the connecting spring 29 away from the inclined block 23 is fixedly installed on the outer wall of the dust cover 21. When the top of the inclined block 23 is separated from the outer wall of the electric drill 1, the connecting spring 29 is fixedly installed on the outer wall of the dust cover 21. The elasticity of 9 can drive the inclined block 23 to slide upward and reset. An L rod 210 is fixedly installed on the side wall of the inclined block 23. The outer wall of the push rod 211 is fixedly installed on the outer wall of the L rod 210 and fits against the inner wall of the hollow rod 27. When the inclined block 23 slides upward and resets, it will drive the L rod 210 to move upward synchronously. When the L rod 210 moves upward, it will drive the push rod 211 to move against the inner wall of the hollow rod 27. At the same time, the push rod 211 will push the hollow rod 27 upward, causing the hollow rod 27 to drive the rotating shaft 22 to rotate.
[0026] The aforementioned cleaning mechanism 3 includes a sliding plate 31, an inclined groove 32, a return spring 33, a brush 34, and a connecting rod 35. The sliding plate 31 is slidably connected to the inner wall of the dust cover 21. The sliding plate 31 has an inclined groove 32. A return spring 33 is fixedly installed on the side wall of the sliding plate 31. The end of the return spring 33 away from the sliding plate 31 is fixedly installed on the inner wall of the dust cover 21. When the handle 26 is pushed to make the dust hopper 25 move the dust cover 21 closer to the wall, the sliding plate 31 will contact the wall first before the dust cover 21 contacts the wall. After the sliding plate 31 contacts the wall, the sliding plate 31 is stationary, while the dust cover 21 continues to move closer to the wall and stretch the return spring 33. A brush 34 is slidably connected to the inner wall of the dust cover 21. The brush 34 can sweep the dust attached to the surface of the baffle 28 into the dust hopper 25 by sliding, so that the dust hopper 25 can fully store the dust. A connecting rod 35 is fixedly installed on the top of the brush 34. The end of the connecting rod 35 away from the brush 34 is attached to the inner wall of the inclined groove 32. When the sliding plate 31 is in a stationary state when it contacts the wall, the dust cover 21 will drive the brush 34 to move synchronously as it continues to approach the wall. At this time, the brush 34 will drive the connecting rod 35 to move against the inner wall of the inclined groove 32. Under the guidance of the inclined groove 32 and with the help of the connecting rod 35, the brush 34 can slide laterally on the inner wall of the dust cover 21.
[0027] Working principle: When drilling into the wall, first place the drill bit of the electric drill 1 against the wall. Then push the handle 26 to make the dust hopper 25 slide and adhere to the dust cover 21 on the outer wall of the electric drill 1. At the same time, the dust cover 21 will stretch the positioning spring 24. Simultaneously, the dust cover 21 will move the inclined block 23 synchronously. When the top of the inclined block 23 disengages from the outer wall of the electric drill 1, the elasticity of the connecting spring 29 can drive the inclined block 23 to slide upward and reset. At this time, the inclined block 23 will drive the L rod 210 to move upward synchronously. As the L rod 210 moves upward, it will drive the push rod 211 to adhere to the hollow wall. As the inner wall of rod 27 moves, push rod 211 pushes hollow rod 27 upward, causing hollow rod 27 to drive rotating shaft 22 to rotate. Simultaneously, rotating shaft 22 drives baffle 28 to rotate synchronously, thus separating adjacent sets of baffles 28. At this point, electric drill 1 can be started to drill a hole in the wall. Meanwhile, dust generated during drilling is blocked by dust cover 21, concentrating inside the dust cover 21 to prevent dust from splashing and polluting the environment, thus avoiding interference with the drilling process. Simultaneously, the dust generated during drilling falls into the dust hopper 25 through the gap between adjacent sets of baffles 28. To prevent dust from scattering and polluting the indoor environment, after drilling is completed, the handle 26 is released. At this time, the elasticity of the positioning spring 24 can drive the dust cover 21 to slide and reset on the outer wall of the electric drill 1, thereby exposing the drill bit of the electric drill 1. At the same time, during the sliding reset process, the dust cover 21 will drive the inclined block 23 to move synchronously and gradually approach the electric drill 1. When the inclined block 23 contacts the electric drill 1, it will be squeezed by the electric drill 1, which will cause the inclined block 23 to slide downward on the inner wall of the dust cover 21 and stretch the connecting spring 29. At this time, the inclined block 23 will drive the L rod 210 to move downward synchronously. As 210 moves downward, it causes push rod 211 to move against the inner wall of hollow rod 27. At the same time, push rod 211 pushes hollow rod 27 downward, causing hollow rod 27 to drive rotating shaft 22 to rotate. Simultaneously, rotating shaft 22 drives baffle 28 to rotate synchronously, so that adjacent baffles 28 can be brought together. At this time, baffle 28 can block the top of ash hopper 25, preventing ash stored inside ash hopper 25 from leaking to the outside and polluting the surrounding environment. When it is necessary to pour out the ash stored inside ash hopper 25, rotate handle 26 to separate it from ash hopper 25. At this time, the ash inside ash hopper 25 can be discharged downward.
[0028] As the handle 26 pushes the dust hopper 25 and the dust cover 21 to gradually approach the wall, the sliding plate 31 will contact the wall before the dust cover 21 does. After the sliding plate 31 contacts the wall, it is stationary, while the dust cover 21 continues to approach the wall and stretches the return spring 33. At the same time, the dust cover 21 will drive the brush 34 to move synchronously. While the sliding plate 31 is stationary, the brush 34 will drive the connecting rod 35 to move against the inner wall of the inclined groove 32. Under the guidance of the inclined groove 32 and in conjunction with the connecting rod 35, the brush 34 can slide laterally on the inner wall of the dust cover 21. The sliding of the brush 34 can sweep the dust attached to the surface of the baffle 28 into the interior of the dust hopper 25, so that the dust hopper 25 can fully store the dust and prevent the dust on the surface of the baffle 28 from floating out and polluting the surrounding environment.
[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
