Description

Technical Field

[0001] This utility model relates to the field of electric drill technology, specifically to an electric drill with dustproof function. Background Technology

[0002] In existing technologies, during construction, electric drills are frequently used to drill holes in concrete structures, such as to install expansion bolts and pipes. In such scenarios, a large amount of dust is generated. During use, existing dustproof devices typically use sealing rings for sealing. After prolonged operation, the sealing rings will be damaged, eventually allowing dust to enter. Once the dust enters, it cannot be collected, leading to dust accumulation and affecting the service life of the electric drill.

[0003] Therefore, a dustproof electric drill was proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Example 1

[0024] A preferred embodiment of the dustproof electric drill provided by this utility model is as follows: Figure 1-5 As shown: A dustproof electric drill includes a drill body 1, a handle 2 fixedly installed at the bottom of the drill body 1, a drill bit 3 movably installed on one side of the drill body 1, a dust-collecting component 4 provided on the surface of the drill bit 3, and a collection component 5 provided on the surface of the dust-collecting component 4.

[0025] The dust collection component 4 specifically includes: a hollow sleeve 411, which is movably fitted on the outer wall of the drill bit 3; a threaded block 412, which is circumferentially fixed on the outer wall of the hollow sleeve 411; a dust collection disc 413, which is movably fitted on the outer wall of the drill bit 3; a threaded block 414, which is circumferentially fixed on the outer wall of the dust collection disc 413; a mounting bracket 417, which is circumferentially fixed on the outer wall of the electric drill body 1; and a recessed block 419, which is circumferentially fixed on the outer wall of the hollow sleeve 411.

[0026] The back of the dust collection plate 413 is in contact with the surface of the hollow sleeve 411. A screw 415 is threaded between the inner wall of the first threaded block 412 and the inner wall of the second threaded block 414. One end of the screw 415 extends to the outside of the second threaded block 414, and an adjusting block 416 is fixedly installed on one end of the screw 415.

[0027] A recessed block 418 is fixedly installed on the surface of the mounting bracket 417. A limit block 4111 is provided on one side of the inner wall of the recessed block 419. A connecting rod 4112 is fixedly installed on one side of the limit block 4111. The other end of the connecting rod 4112 movably passes through one side of the inner wall of the recessed block 419 and extends to the outside of the recessed block 419. A cross disc 4113 is fixedly installed on the other end of the connecting rod 4112.

[0028] A spring 4114 is movably sleeved on the outer wall of the connecting rod 4112. One end of the spring 4114 is fixedly connected to one side of the recess 418, and the other end of the spring 4114 is fixedly connected to one side of the cross disc 4113. A locking block 4115 is fixedly installed on the other side of the cross disc 4113. The other side of the locking block 4115 extends to the inner wall of the recess 418 and engages with it.

[0029] In this example, the dust is vacuumed by the vacuuming component 4, which works in conjunction with the collection component 5. The dust enters the hollow sleeve 411 through the hole on the vacuuming disc 413 and is then collected. When it is necessary to clean the inside of the hollow sleeve 411, the operator rotates the adjusting block 416 to drive the screw 415 to rotate. Under the action of the first threaded block 412 and the second threaded block 414, the screw 415 moves and disengages from the fixed position. Then the vacuuming disc 413 can be removed from the drill bit 3, and the inside of the hollow sleeve 411 can be cleaned to facilitate subsequent cleaning and ultimately achieve the purpose of vacuuming. Example 2

[0030] Based on Embodiment 1, a preferred embodiment of the dustproof electric drill provided by this utility model is as follows: Figure 1-5 As shown: The collection component 5 specifically includes: a connecting pipe 511, which is connected to the bottom of the hollow sleeve 411; a recycling box 512, which is connected to the other end of the connecting pipe 511; and a bracket 513, which is fixedly installed at equal intervals on both sides of the bottom of the recycling box 512.

[0031] The bottom of the recycling bin 512 is provided with an exhaust port 514. Magnets 515 are fixedly installed on both sides of the recycling bin 512. A connecting frame 516 is fixedly installed on the top of the inner wall of the recycling bin 512. The connecting frame 516 is connected to the other end of the connecting pipe 511. A suction fan 517 is fixedly installed between the inner walls of the connecting frame 516.

[0032] The inner walls of the recycling bin 512 are fixedly installed with grooved plates 518 at equal intervals on both sides. A fixed frame 519 is slidably connected between the inner walls of the grooved plates 518. A filter screen 5111 is fixedly installed between the inner walls of the fixed frame 519. One side of the fixed frame 519 moves through the inner wall surface of the recycling bin 512 and extends to the outside of the recycling bin 512. A connecting plate 5112 is fixedly installed on one side of the fixed frame 519. Magnets 5113 are fixedly installed on both sides of the connecting plate 5112. The surface of magnet 5113 is attracted to the surface of magnet 515. A handle 5114 is fixedly installed on the other side of the connecting plate 5112.

[0033] In this example, dust is collected and filtered by the collection component 5. The suction fan 517 is started to rotate. The dust enters the collection box 512 through the connecting pipe 511. The filter screen 5111 performs secondary filtration. The primary filter layer uses a metal filter screen to filter larger particles, and the bottom layer uses activated carbon to adsorb harmful gases and fine dust. The filtered air is discharged through the exhaust port 514, thus achieving the collection function.

[0034] Working principle: First, the suction fan 517 is started and rotates. The dust suction component 4 sucks up dust, which enters the hollow sleeve 411 through the holes in the suction disc 413 and is then collected. When cleaning the inside of the hollow sleeve 411 is required, the operator rotates the adjusting block 416, causing the screw 415 to rotate. Under the action of the first threaded block 412 and the second threaded block 414, the screw 415 moves and disengages, allowing the suction disc 413 to be removed from the drill bit 3. The inside of the hollow sleeve 411 can then be cleaned for later cleaning. When disassembling the hollow sleeve 411 is required, the operator pushes the cross disc 4113, causing the connecting rod 4112 and the limiting block 4111 to move, compressing the spring 4114. At this time, the locking block 4115 disengages from the groove block 418, allowing the hollow sleeve 411 to be disassembled. The surface of the drill bit 3 is made of polytetrafluoroethylene, which has an extremely low coefficient of friction and generates very little friction, reducing wear between the perforated sleeve 411 and the drill bit 3. Then, the dust is filtered and collected by the collection component 5. The dust enters the recycling box 512 through the connecting pipe 511. The filter screen 5111 performs secondary filtration. The primary filter layer uses a metal filter screen to filter larger particles, and the bottom layer uses activated carbon to adsorb harmful gases and fine dust. The filtered air is discharged through the exhaust port 514. When the filter screen 5111 needs to be cleaned, the connecting plate 5112 is pulled outward by the handle 5114, which drives the fixing frame 519 to slide out of the groove plate 518. Then the filter screen 5111 is cleaned, achieving recycling. The stability of the connecting plate 5112 is ensured by the attraction between magnet one 515 and magnet two 5113, thereby achieving the function of dust suction and collection.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
