The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0021] The following describes an embodiment of the utility model based on its overall structure.

[0022] A dustproof drilling device for metal door and window engineering, such as Figure 1-4 As shown, it comprises a main body 1, a transmission shaft 2 is rotatably connected inside the main body 1, and a drill bit 4 is fixed at the end of the transmission shaft 2;

[0023] An impeller 3 located inside the main body 1 is fixed to the outside of the transmission shaft 2, a dust removal frame 5 is fixed to the top of the main body 1, and a cavity 6 is opened inside the dust removal frame 5, and multiple groups of nozzles 7 connected to the cavity 6 are evenly fixed inside the dust removal frame 5, and a drainage frame 9 penetrating the main body 1 is fixed to the bottom of the main body 1, wherein the drainage frame 9 is connected to the external sewage cylinder through a pipeline;

[0024] A water inlet pipe 8 penetrating the main body 1 is fixed on the top of the dust removal frame 5, and the water inlet pipe 8 is connected to the cavity 6, wherein the water inlet pipe 8 is connected to an external water tank, and under the action of a micro water pump, water is transported to the inside of the dust removal frame 5;

[0025] A plurality of groups of air inlet holes 10 located on one side of the dust removal frame 5 are evenly arranged on the surface of the main body 1, and a plurality of groups of air exhaust holes 11 are evenly arranged on one side of the main body 1. The transmission shaft 2 drives the impeller 3 to rotate at the same time, and then the impeller 3 rotates to absorb external air through the plurality of groups of air inlet holes 10. The airflow entering the main body 1 will carry the dust generated by drilling and move to the inside of the main body 1. At this time, under the action of the plurality of groups of nozzles 7 on the dust removal frame 5, water is sprayed on the dust entering the main body 1. After the water contacts the dust, the water and the dust are discharged to the outside through the drainage frame 9 under the action of their own gravity. The overall dust removal effect is good, which effectively avoids the problem of dust flying everywhere and improves the air quality of the overall working environment.

[0026] See also Figure 2 and Figure 3 A dust cover 12 is movably connected to one side of the main body 1, and a telescopic groove 13 cooperating with the dust cover 12 is opened on one side of the main body 1. The top and bottom of one side of the telescopic groove 13 are fixed with a guide rod 14 extending to the inside of the dust cover 12, and a spring 15 located on the outside of the guide rod 14 is fixed between the dust cover 12 and the main body 1. By setting the above structure, the utility model can always fit the dust cover 12 with the wall under the action of the spring 15.

[0027] See also Figure 1 , Figure 2 and Figure 4 A support frame 16 that matches the transmission shaft 2 is fixed inside the main body 1, a connecting frame 18 that is connected to external equipment is fixed on one side of the main body 1, a handle 17 is fixed at the bottom of the main body 1, and a rubber ring is fixed on the outside of the handle 17. The utility model is provided with the above structure, wherein the support frame 16 plays a role of active support for the transmission shaft 2, the connecting frame 18 is convenient for mutual connection with the casing of the external driving equipment, and the handle 17 is convenient for the staff to operate and use.

[0028] The working principle of the utility model is as follows: when in use, the main body 1 is connected to the handheld driving device through the connecting frame 18, wherein the water inlet pipe 8 is connected to the external water pipe, and a micro water pump is connected to the end of the external water pipe. The staff only needs to prevent the water pump from being placed inside the water tank to perform the pumping operation, so that water enters the water inlet pipe 8 through the external pipe;

[0029] Furthermore, the end of the drainage rack 9 is connected to a drainage pipe, wherein the end of the drainage pipe is placed inside the sewage barrel to collect the sewage centrally;

[0030] The connecting frame 18 is engaged with the housing of the handheld driving device, so that the transmission shaft 2 is connected to the driving shaft of the driving device, and then the drill bit 4 can be driven by the transmission shaft 2 to rotate and perform drilling operations on the wall;

[0031] At the same time, the transmission shaft 2 drives the impeller 3 to rotate, and then the impeller 3 rotates to absorb external air through the multiple groups of air inlet holes 10. The airflow entering the main body 1 will carry the dust generated by the drilling and move to the inside of the main body 1. At this time, under the action of the multiple groups of nozzles 7 of the dust removal rack 5, water is sprayed on the dust entering the main body 1. After the water contacts the dust, the water and the dust are discharged to the outside through the drainage rack 9 under the action of their own gravity. The overall dust removal effect on the dust is good, which effectively avoids the problem of dust flying everywhere and improves the air quality of the overall working environment.

[0032] Furthermore, the water sprayed by the multiple groups of nozzles 7 can not only combine with the dust to remove the dust, but also part of the sprayed water will contact the surface of the transmission shaft 2 and the drill bit 4, which has a cooling effect on the transmission shaft 2 and the drill bit 4 to a certain extent, thereby improving the stability of the drill bit 4 during operation and avoiding the situation where the drill bit 4 is damaged due to the accumulation of temperature inside the drill bit 4 during the drilling process;

[0033] Furthermore, when drilling, the worker positions the hole and makes the end face of the dust cover 12 contact the wall. At this time, as the worker applies force to make the drill bit 4 drill the wall, the dust cover 12 contracts relative to the main body 1. Under the action of the spring 15, the end face of the dust cover 12 always fits against the wall to prevent dust generated by drilling from leaking.
