Problems solved by technology

However, due to the long drill bit, the drill bit will jump a lot when working, and the drill bit will directly drive the fan blade to rotate, which will cause a lot of jump, which will affect the use effect

Embodiment 1

[0044] The first embodiment of the hand-held drilling machine with dust removal device of the present invention is as follows: figure 1 Shown, comprise drilling machine housing 19, drill chuck 17, drill bit 13, auxiliary handle 18 and telescoping tube 22; The interior of drilling machine housing 19 is equipped with motor, and its rear part is main handle 20; Drill chuck 17 is located at the front of the drilling machine housing 19 and is driven by a motor, which is used to clamp the drill bit 13 for drilling operations; the auxiliary handle 18 is installed on the drilling machine housing 19, and the auxiliary handle 18 is close to the drill chuck 17; One end of telescopic tube 22 is connected on the housing of dust collecting seat 3, and the other end of telescopic tube 22 is installed on the auxiliary handle 18; A spring 16 is provided inside, and a scale mark 801 and a positioning block 14 are provided on the inner telescopic tube 8 , and the depth of the drill hole drilled ...

Embodiment 2

[0054] Figure 8 It is a structural schematic diagram of the second embodiment of the hand-held drilling machine with dust removal device of the present invention, as Figure 8 As shown, the difference between the second embodiment of the present invention and the first embodiment is that one end of the telescopic tube 22 is connected to the dust collecting seat 3, and the other end of the telescopic tube 22 is installed on the drilling machine housing 19 superior.

Embodiment 3

[0056] Figure 9 It is a structural schematic diagram of the third embodiment of the hand-held drilling machine with dust removal device in the present invention, Figure 10 It is a structural schematic diagram of the dust removal device of the third embodiment. Such as Figure 9 and Figure 10 As shown, the difference between the third embodiment of the present invention and the first embodiment is that the air inlet is changed to an air outlet 305, and the air outlet 305 is arranged on the housing of the dust collecting seat 3; The wind flow direction 7 is opposite to that of the first embodiment, the air suction port 306 is located at the front end of the dust collecting seat 3, and the lower air channel 303 starts from the hole 21 when the drill bit is working, extends downward and communicates with the air chamber 304, and the wind flow As shown in the wind flow direction 7, it enters the orifice 21 from the air suction port 306, and then enters the air chamber 304 thr...

Abstract

The invention relates to a handheld drilling machine with a dust removal device. The handheld drilling machine comprises a drilling machine shell, a drill chuck, a drill bit and the dust removal device. The dust removal device comprises a dust collection base, an aligning rubber sleeve, a fan blade and a dust collection box, wherein the fan blade is installed in the dust collection base through a bearing, an inner circular conical surface opened backwards is arranged on the fan blade, the aligning rubber sleeve is arranged on the drill bit in a penetrating mode and rotates along with the drill bit, the circumference of the aligning rubber sleeve is an outer circular conical surface, and the outer circular conical surface can be attached to the inner circular conical surface of the fan blade to drive the fan blade to rotate; the fan blade sucks external air in or exhausts internal air when rotating, an air channel used for controlling the flowing direction of the air is formed in the dust collection base or the dust collection box, and through the flowing of the air, dust generated in the hole drilling process is thoroughly brought into the dust collection box. The handheld drilling machine is reasonable in structure, small in size and low in cost and can prevent the drill bit from driving the fan blade to jitter, and the dust is removed more thoroughly.

Description

technical field [0001] The invention relates to a hand-held electric tool, in particular to a hand-held drilling machine with a dust removal device. Background technique [0002] In the prior art, there are three main solutions for hand-held drilling machines such as percussion drills or electric hammer dust removal: first, an external vacuum cleaner type, which mainly involves the dust suction pipe passage and fixing method, because the vacuum cleaner Larger suction, better dust collection effect. However, a vacuum cleaner needs to be configured, which is troublesome to use. Second, use the machine's own fan blade suction type. This dust removal method is easy to use because it does not need to be connected to a vacuum cleaner. However, the actual dust collection effect of this method is not ideal, and it also affects the normal air intake of the motor. Thirdly, the dust-absorbing blades are separately installed on the motor. This kind of dust-removal scheme does not nee...
