Therefore, it should not be construed as a limitation to the present invention.

[0026] As Figures 1 to 8 shown, a drilling device for interior design and decoration includes a drill. The drill includes a grip 1, a drill housing 2, a drill bit 3 and a driving device. The grip 1 is fixedly connected to the drill housing 2. The driving device is used to drive the drill bit 3 to perform lifting and rotating movements. A guide groove 4 is opened at the upper end of the side wall of the drill housing 2. A connecting rod 5 is slidably connected between the two side walls of the guide groove 4. A first bearing 6 is rotatably connected to the drill bit 3. One end of the connecting rod 5 located inside the drill housing 2 is fixedly connected to the first bearing 6. An outer tube 7 is provided at one end of the connecting rod 5 located outside the drill housing 2. The inner side of the upper end of the outer tube 7 is slidably connected with an inner tube 8. The upper end of the inner tube 8 is fixedly connected with an inclined tube 9 inclined towards the drill housing 2. The upper end of the inclined tube 9 is fixedly connected with a vertical tube 10 coaxial with the drill bit 3. The lower end of the outer tube 7 is detachably connected with an ash receiving container 11. A limit ring 12 is provided at the upper end of the outside of the inner tube 8. A first elastic member 13 is provided between the limit ring 12 and the outer tube 7. The upper end of the drill bit 3 passes through the inclined tube 9 and extends into the vertical tube 10.

[0027] Preferably, the ash receiving container 11 is made of a transparent material, which is convenient for observing the dust collection amount in the ash receiving container 11 and timely disassembling and cleaning.

[0028] During specific use, the upper end of the vertical pipe 10 is abutted against the lower surface of the structural floor, and the driving device drives the drill bit 3 to perform lifting and rotating motions for drilling. As the drilling progresses, the outer pipe 7 reciprocally compresses the first elastic member 13 with the drill bit 3, so that the upper end of the vertical pipe 10 always abuts against the lower surface of the structural floor, which is beneficial to preventing dust leakage. The first elastic member 13 can also effectively reduce the vibration transmission during drilling, improve the sealing performance, and is beneficial to preventing dust leakage. Most of the generated dust enters the vertical pipe 10 under the action of gravity, and then, under the guiding action of the inclined pipe 9, successively passes through the inner pipe 8 and the outer pipe 7, and is finally collected in the ash receiving container 11.

[0029] To achieve the purpose of improving the dust collection effect, preferably, a second bearing 14 is rotatably connected to the side wall of the inclined pipe 9, and a rubber sealing ring 15 for the drill bit 3 to pass through is arranged on the inner wall of the second bearing 14. The drill bit 3 passes through the rubber sealing ring 15. During the drilling process, the drill bit 3 drives the second bearing 14 to rotate relative to the inclined pipe 9, with good sealing performance, which is beneficial to avoiding dust leakage and improving the dust collection effect.

[0030] To achieve the purpose of improving the dust collection effect, preferably, an anti-static dust-proof cover 16 is arranged at the upper end of the vertical pipe 10. The dust-proof cover 16 is in the shape of a horn with a large upper end and a small lower end, expanding the sealing and dust-proof range, and avoiding the vibration generated during drilling from being transmitted to the surrounding of the drilled hole through the wall, causing the surrounding materials to fall off and posing a hazard to the staff or the working environment.

[0031] To achieve the purpose of improving the dust collection effect, preferably, an inflatable rubber sealing ring 17 is arranged at the upper edge of the dust-proof cover 16. Before drilling, inflating the inflatable rubber sealing ring 17 can increase the degree of fitting with the wall, improve the sealing effect, be beneficial to avoiding dust leakage, and improve the dust collection effect.

[0032] To achieve the purpose of improving the dust collection effect, preferably, an air nozzle 19 is arranged on the inner side of the upper end of the dust-proof cover 16 and is located below the inflatable rubber sealing ring 17. The air outlet direction of the air nozzle 19 is inclined downward. During the drilling process, the air nozzle 19 blows air downward obliquely, so that the airflow drives the tiny dust to be collected in the ash receiving container 11, which is beneficial to improving the dust collection effect.

[0033] To achieve the purpose of improving the dust collection effect, preferably, a spiral ventilation and guiding groove 18 is arranged on the inner surface of the dust-proof cover 16. This spiral design can enable the airflow to form a stable vortex flow inside the dust-proof cover 16, guiding the dust to efficiently flow along the ventilation and guiding groove 18 to the ash receiving container 11, avoiding the deposition and turbulent flow of dust inside the dust-proof cover 16, and greatly improving the dust collection effect.

[0034] Preferably, the bottom wall of the ash receiving container 11 is a high-efficiency HEPA filter 42, which can capture extremely small dust particles, ensuring that the air discharged from the ash receiving container 11 meets environmental emission standards and avoids secondary pollution.

[0035] In order to achieve the purpose of improving the dust collection effect, preferably, a valve housing 20 is provided inside the drilling rig housing 2, an air guide pipe 21 and a first air pipe 22 are provided at the lower end of the valve housing 20, a second air pipe 23 is provided on the side wall of the valve housing 20, the air guide pipe 21 is connected to an air pump, the first air pipe 22 is connected to the inflatable rubber sealing ring 17, the second air pipe 23 is connected to the air nozzle 19, a valve core 23 is slidably connected inside the valve housing 20, a second elastic member 24 is provided between the valve core 23 and the inner top wall of the valve housing 20, and the air pump supplies air to the valve housing 20 through the air guide pipe 21. Blow air inside. Before drilling, the air pressure at the bottom of the valve housing 20 is relatively small, and no air enters the second air pipe 23. Air enters the inflatable rubber sealing ring 17 from the first air pipe 22 to increase the fit between the dust cover 16 and the wall. After the inflatable rubber sealing ring 17 is filled with air, the air pressure at the bottom of the valve housing 20 gradually increases to a value greater than the elastic force of the second elastic member 24. The valve core 23 moves upward, the second air pipe 23 is connected, and the air flow is blown toward the inside of the dust cover 16 through the air nozzle 19. At this time, drilling operation can be carried out, so that the air flow drives the fine dust to be collected in the ash receiving container 11.

[0036] Preferably, the driving device includes a driving part 25 arranged on the drilling rig housing 2, a mounting plate 26 is arranged inside the drilling rig housing 2, a driving gear 27 is rotatably connected to the mounting plate 26, an annular cam 29 is arranged on the upper surface of the driving gear 27, the output end of the driving part 25 is fixedly connected to the driving gear 27, a sleeve 30 is rotatably connected to the mounting plate 26, a driven gear 28 meshing with the driving gear 27 is arranged on the upper end of the sleeve 30, a spline groove 31 is arranged on the inner wall of the sleeve 30, a spline 32 matched with the spline groove 31 is arranged on the drill bit 3, and a roller 33 is arranged on the first bearing 6, which is in close contact with the cam surface of the annular cam 29 under the elastic force of the first elastic member 13.

[0038] During use, the driving part 25 drives the driving gear 27 to rotate, and the driving gear 27 drives the driven gear 28 to rotate. At the same time, the drill bit 3 makes a lifting and rotating motion under the driving of the annular cam 29 to drill the lower surface of the structural floor. During the drilling process, the driving part 25 drives the driving bevel gear 40 to rotate, and the driving bevel gear 40 drives the turntable 34 to rotate through the driven bevel gear 41. The turntable 34 drives the piston rod 36 and the piston 38 to perform a piston motion inside the piston cylinder 37 through the push-pull rod 35, so as to extract external air and deliver it to the inflatable rubber seal ring 17 and the air nozzle 19. The airflow ejected from the air nozzle 19 drives the tiny dust to be collected in the ash receiving container 11, and the airflow is discharged after being purified by the high-efficiency HEPA filter.

[0039] Compared with the prior art, through the cooperative setting of the grip 1, the drilling machine housing 2, the drill bit 3, the guide groove 4, the connecting rod 5, the first bearing 6, the outer tube 7, the inner tube 8, the inclined tube 9, the vertical tube 10, the ash receiving container 11, the limiting ring 12 and the first elastic member 13 of the present invention, the upper end of the vertical tube 10 is abutted against the lower surface of the structural floor, and the driving device drives the drill bit 3 to make a lifting and rotating motion for drilling. As the drilling progresses, the outer tube 7 reciprocally compresses the first elastic member 13 along with the drill bit 3, so that the upper end of the vertical tube 10 always abuts against the lower surface of the structural floor, which is beneficial to preventing dust leakage. The first elastic member 13 can also effectively reduce the vibration transmission during drilling, improve the sealing performance, and is beneficial to preventing dust leakage. Most of the generated dust enters the vertical tube 10 under the action of gravity, and then, under the guiding action of the inclined tube 9, passes through the inner tube 8 and the outer tube 7 in sequence, and finally is collected in the ash receiving container 11, without causing adverse effects on the workers' bodies and the working environment.
