DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] The following will be described in detail with reference to the drawings in the embodiments of the present application. Figures 1-4The application is further described in detail.

[0028] Embodiment 1

[0029] Please refer to Figures 1-4 The embodiment provides a technical scheme: an electric drill with a dust collection device, comprising: an electric drill body 1, a first pipe 2, a second pipe 3, a dustproof box 4, a dust collector body 5, and a separation mechanism 6.

[0030] The output end of the electric drill body 1 is clamped and fixed with a drill bit. The main working principle of the electric drill is that a small-capacity motor is rotated or reciprocated by electromagnetism, so that the motor rotor cuts work in the magnetic field to rotate, and then drives the operating device through a transmission mechanism to drive the gear to increase the power of the drill bit, so that the drill bit can scrape the surface of the object, and finally realize the purpose of penetrating the object. The above is the prior art, and the following will not be described in detail. The first pipe 2 is fixedly arranged at the bottom of the electric drill body 1. The first pipe 2 is connected by a circular fixing piece through a bolt. The second pipe 3 is sleeved at one end of the first pipe 2. The second pipe 3 cooperates with the first pipe 2 to realize the circulation of internal particle fragments and dust. The second pipe 3 can move in the first pipe 2, so that the second pipe 3 can move in the first pipe 2 when the drill bit of the electric drill body 1 moves to drill, thereby ensuring that the second pipe 3 moves in the first pipe 2 to ensure the circulation of internal particle fragments and dust. The bottom of the dustproof box 4 is connected with the second pipe 3. The dustproof box 4 can transport particle fragments and dust through the second pipe 3. A circular hole is formed in the inside of the dustproof box 4 for the movement of the drill bit of the electric drill body 1. The circular hole can provide the drill bit of the electric drill body 1 to stably drill the wall. A circular hole is formed in the outer wall of the middle part of the dustproof box 4. The circular hole can connect the structures. The material of the dustproof box 4 is transparent plastic, which can facilitate personnel to observe the internal condition.

[0031] The dust collector body 5 is connected with the other end of the first pipe 2. The dust collector body 5 can absorb the dust in the first pipe 2 through its own suction force. The separation mechanism 6 is arranged in the inside of the dustproof box 4. The separation mechanism 6 can separate the particle fragments and dust in the dustproof box 4 to avoid the blockage of the first pipe 2 and the second pipe 3. The separation mechanism 6 comprises a filter plate 601 which is adhered at an angle of 45° in the inside of the dustproof box 4. The filter plate 601 can separate the particle fragments and dust. A push block 604 is slidingly connected in the inside of the dustproof box 4. The push block 604 moves to move the blocked particle fragments on the filter plate 601. A third pipe 607 is connected with the circular hole of the dustproof box 4 at one end. The particle fragments can be discharged through the third pipe 607. A collection box 608 is connected with the other end of the third pipe 607. The particle fragments discharged by the third pipe 607 can be stored in the inside of the collection box 608.

[0032] When the electric drill main body 1 drills a hole in a wall, the generated particle debris and dust will be stored in the dustproof box 4, and when stored in the dustproof box 4, the particle debris and dust will be separated by the filter plate 601, and the particle debris will be stored above the filter plate 601, at this time the dust collector main body 5 will be connected with the dustproof box 4 through the No. 1 pipe 2 and the No. 2 pipe 3, so as to store the dust, and the particle debris passes through the inclined filter plate 601 and flows into the inside of the collecting box 608 through the No. 3 pipe 607, and is stored, and when the particle debris blocks the filter plate 601, the moving block 604 will move the particle debris.

The hole 602 is composed of a rectangular through hole and a sliding groove opened on the upper and lower ends of the inner wall. The sliding groove can provide the internal structure to move stably. The pulley 603 is slidingly connected in the sliding groove of the two groups of holes 602. The pulley 603 moves in the sliding groove, thereby providing the connected structure to move synchronously stably. The number of the pulleys 603 is two, which can be connected at both ends of the structure, thereby providing effective stability.

[0036] One end of the pulley 603 is welded with the block 604, and the other end of the block 604 is welded with the pulley 603.

The connecting shaft 605 can connect the structures. The circular pipe 606 is sleeved on the connecting shaft 605. The circular pipe 606 can rotate on the connecting shaft 605, thereby changing the angle. The circular pipe 606 is arranged on the outside of the dustproof box 4. The rubber sealing block 609 is bonded on the upper and lower ends of the rectangular through hole of the hole 602. The connecting shaft 605 is arranged inside the two groups of rubber sealing blocks 609. The rubber sealing block 609 can block the hole 602, thereby sealing the inside of the dustproof box 4 without affecting the movement of the connecting shaft 605. The handle 610 is welded on the circular pipe 606. The handle 610 can be held by a person, thereby driving the circular pipe 606 and the internal structure to move synchronously.

[0039] Firstly, when the electric drill main body 1 drills the wall, the particle fragments and dust generated at this time will be stored in the dustproof box 4.

[0040] Secondly, when stored in the dustproof box 4, the particle fragments and dust will be separated by the filter plate 601, and the particle fragments will remain above the filter plate 601, at this time the dust collector main body 5 will be connected with the dustproof box 4 through the first pipe 2 and the second pipe 3 to store the dust, and the particle fragments will pass through the filter plate 601 placed obliquely to flow into the inside of the collecting box 608 through the third pipe 607 for storage.

[0041] Finally, when it is needed to move the particle fragments above the filter plate 601 by moving the stirring block 604, the handheld handle 610 can be connected through the circular tube 606 to change the angle on the connecting shaft 605, the connecting shaft 605 is connected with the pulley 603, the pulley 603 is connected with the stirring block 604, so that when the handle 610 moves, the pulley 603 in the hole 602 can stably drive the stirring block 604 to move, and in the process of moving the connecting shaft 605, the rubber sealing block 609 can not affect the movement of the connecting shaft 605, and the rubber sealing block 609 can be sealed in real time by changing the shape of the dustproof box 4.
