Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
The first embodiment is as follows:
referring to fig. 1, 2, 3 and 5, an electric drill with a dustproof function comprises an electric drill body 1 and a drill bit 2 installed on the electric drill body 1, wherein a cavity is arranged in the electric drill body 1, the cavity is divided into a first cavity 14 and a second cavity 12 through a piston 8, a first magnetic block 6 is embedded in the outer side wall of the drill bit 2, a second magnetic block 7 is embedded in the upper end of the piston 8, the same poles of the opposite surfaces of the first magnetic block 6 and the second magnetic block 7 are repelled, slide bars 10 are fixed on the upper inner wall and the lower inner wall of the cavity, the slide bars 10 penetrate through the piston 8, springs 9 are sleeved on the slide bars 10, an annular groove 3 is arranged on the front side of the electric drill body 1, an annular folding air bag 4 is bonded in the annular groove 3, an elastic rope is connected between the left inner wall and the right inner wall of the annular folding air bag 4, the annular folding air bag 4 is communicated with the second cavity 12 through an air, the upper surface of the tail end of the annular folding air bag 4 positioned at the lower part is provided with a plurality of air outlet pipes 18, a one-way valve in the air inlet 11 ensures that air can only be sucked from the air inlet 11 in one way, and a one-way valve in the air pipe 13 ensures that air can only be discharged from the air pipe 13 in one way.
In the invention, the direction of the air outlet pipe 18 is slightly inclined forwards, dust falling from the punched hole falls along the wall surface, and the dust can be blown back into the dust cover formed by the annular folding air bag 4 by the forward-inclined air. The end of the annular folded air bag 4 is bonded with a sealing gasket 19 to further prevent dust from being scattered through the gap. The upper and lower both sides of annular folding gasbag 4 all are equipped with the device mouth, and the device mouth bonds has transparent cloth 5, and the user can see through transparent cloth 5 and observe the position of punching and the condition of punching.
In the embodiment, the electric drill body 1 is started, the drill bit 2 starts to rotate, the drill bit 2 drives the first magnetic block 6 to rotate, when the electric drill rotates to the position right below, the opposite surfaces of the first magnetic block 6 and the second magnetic block 7 repel each other in the same stage, so that the second magnetic block 7 moves downwards, the piston 8 is driven to move downwards in the cavity, the gas in the second cavity 12 is squeezed into the annular folding airbag 4 through the gas pipe 13, when the first magnetic block 6 rotates away from the second magnetic block 7, the first magnetic block is reset through the spring 9, the gas is sucked through the gas suction port 11, reciprocating inflation is realized, the annular folding airbag 4 is inflated and expanded until the drill bit 2 is covered, at the moment, the drill bit 2 can be abutted against the wall surface to drill, dust can be perfectly shielded no matter at which angle to drill, and the pipe diameter of the gas outlet pipe 18 on the annular folding airbag 4 below is far smaller than that of the gas pipe, the gas discharge amount is far less than the air input to guarantee that annular folding gasbag 4 can keep the inflation, and the direction of giving vent to anger of outlet duct 18 leans forward slightly, and the dust that punches and fall on drops along the wall, and the gas that leans forward can blow back the dust to in the dust cover that annular folding gasbag 4 formed, punches the back of finishing, pours the dust of inside collection between, and annular folding gasbag 4 slowly contracts back in the annular groove 3 through inside bungee.
Example two:
referring to fig. 4-5, the difference between the first embodiment and the second embodiment is that an annular tube 16 is embedded in the mounting hole of the drill bit 2, the annular tube 16 is communicated with the first cavity 14 through a connecting tube 17, a plurality of air nozzles 15 inclined toward the drill bit 2 are uniformly distributed on the side wall of the annular tube 16, an air inlet is formed in the inner wall of the first cavity 14, check valves are mounted in the air inlet and the connecting tube 17, the check valves in the air inlet enable air to enter the first cavity 14 from the air inlet only in one direction, and the check valves in the connecting tube 17 enable air to be discharged from the connecting tube only in one direction.
When the electric drill body 1 needs to be lifted to punch upwards, dust easily enters the electric drill body 1 through the mounting port of the drill bit 2 to affect work. In this embodiment, when the spring 9 pushes the piston 8 to return, the gas in the first cavity 14 is pushed into the annular tube 16 through the connecting tube 17, and is finally ejected through the plurality of air ejecting heads 15, and the ejected gas flows outwards along the outer side wall of the drill bit 2, so that dust falling along the drill bit 2 can be blown away, and the dust can be effectively prevented from entering.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
