Embodiment 1

[0030] Such as figure 1 , 2 As shown in .3, a noise-reducing and dust-removing electric drill with a debris collection structure includes an electric drill body 1, and the front end of the electric drill body 1 is provided with debris for collecting falling debris when the wall 2 is punched. The collection structure 3, the debris collection structure includes a front end 4 attached to the wall surface, a middle end 5 with a cavity fixedly connected to the front end 4, a rear end 6 fixedly connected to the middle end 5, and The storage chamber 7 for collecting wall debris is arranged below the middle end 5, the rear end 6 is slidably connected with the electric drill chuck 8, and the cavity of the middle end 5 is provided with an electric drill bit 9 The noise reduction assembly 10 that buffers and weakens the noise generated when colliding with the wall, the noise reduction assembly 10 includes an outer sound-absorbing layer 11 fixedly connected to the inner surface of the mi...

Embodiment 2

[0038] Such as Figure 4 As shown, the similarities with Embodiment 1 will not be repeated, the difference is that in this embodiment, the storage chamber 7 includes an upper end portion 24, and a lower end portion 25 detachably connected to the upper end portion 24, and the upper end portion 24 passes through The connecting piece 26 is fixedly connected with the lower end portion 25 . The storage chamber 7 is divided into two parts, so that the sewage or debris in the storage chamber 7 can be cleaned up for later use. Wherein, the connecting piece 26 includes a threaded rod with a plug at one end, and a nut adapted to the threaded rod. When disassembling and using, the nut is removed from the threaded rod, then the lower end 25 is separated from the upper end 24, and then the lower end 25 is cleaned.

Embodiment 3

[0040] Such as Figure 5 As shown, the similarities with Embodiment 2 will not be described in detail. The difference is that in this embodiment, a dust reduction nozzle 23 for dust reduction is also provided inside the front end 4, and a dust reduction electromagnetic for controlling the water output of the dust reduction nozzle. The valve is not shown in the accompanying drawings, and the dust suppression electromagnetic valve adopts the existing technology, which can realize opening and closing and water volume adjustment. The control system also includes a dust concentration sensor for detecting the dust concentration in the front end of the electric drill. When the dust concentration sensor detects the dust concentration in the front end, the detection signal is sent to the controller, and the controller sends a signal to control the water output of the dust suppression solenoid valve. To the dust suppression solenoid valve. Wherein, the dust concentration sensor can be ...

Abstract

The invention relates to the technical field of building construction, in particular to a noise reduction and dust removal electric drill with a scrap collecting structure. The electric drill comprises an electric drill body and the scrap collecting structure, the scrap collecting structure comprises a front end, a middle end, a rear end and a storage cavity, the front end, the middle end and the rear end are attached to the surface of a wall, the rear end is glidingly connected with an electric drill chuck, a noise reduction assembly is arranged in a cavity of the middle end and comprises an outer sound absorption layer and an inner sound absorption layer, a sound absorption cavity is further formed between the inner sound absorption layer and the outer sound absorption layer, a plurality of buffer springs are arranged in the sound absorption cavity, and the noise reduction and dust removal electric drill further comprises a control system used for ensuring that the noise reduction assembly can absorb sound and reduce noise in real time. The invention further provides a control method of the noise reduction and dust removal electric drill. The electric drill is simple in structure, reasonable in design and convenient to disassemble, time and labor are saved, the real-time noise reduction and sound absorption effects of the electric drill are effectively guaranteed, the construction cost is saved, and the relatively-quiet construction environment of constructors is guaranteed.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a noise reduction and dust removal electric drill with a debris collection structure and a control method thereof. Background technique [0002] With the development of science and technology, power tools are being used more and more widely because of their time-saving and labor-saving features. As an electric tool often used in the construction and decoration process, the electric drill plays an extremely important role and plays a significant role in solving the problem of local drilling. [0003] As we all know, while electric tools bring convenience to users, they also bring some confusion in use. For example, during use, the noise is very loud, and the construction dust is flying, resulting in a poor working environment. Using an electric drill for a long time will cause great damage to the user's breathing attraction and hearing. In response to the above pro...
