Description

Technical Field

[0001] The utility model relates to the technical field of electric drills, in particular to an electric drill dust suction component and an electric drill with the electric drill dust suction component. Background Art

[0002] During the building renovation process, it is often necessary to install various equipment on the facade, such as air conditioner outdoor units or guardrails. At this time, it is necessary to drill holes on the facade to install expansion bolts. The drilling operation needs to be completed with an electric drill.

[0003] When drilling, electric drills generate a lot of dust and debris. Although these debris are relatively small, they still pose a safety risk after falling from a high altitude. The dust generated by the electric drill is blown to the operator's face by the wind, affecting the operator's normal construction. Utility Model Content

[0004] In view of the above-mentioned deficiencies or defects in the prior art, the utility model provides an electric drill dust suction assembly and an electric drill having the electric drill dust suction assembly. The dust suction assembly is installed on the electric drill, and can use a material receiving hopper to receive the debris dropped from the drill bit, and an exhaust fan is provided. The exhaust fan is connected to the material receiving hopper to extract dust from the material receiving hopper and then discharge it from the exhaust port of the exhaust fan, thereby preventing dust from splashing everywhere and affecting the construction of operators.

[0005] In order to achieve the purpose of controlling dust splashing and debris falling during electric drill operation, the utility model provides an electric drill dust suction component.

[0006] The utility model is realized by the following measures: an electric drill dust suction assembly, characterized in that it comprises a mounting seat that can be connected to the electric drill body, the mounting seat is fixedly connected to one end of a support arm, the support arm can be telescopic along its length direction, and the other end of the support arm is provided with a receiving hopper;

[0007] The dust suction component also includes an exhaust fan, a fan of the exhaust fan is connected to the main shaft of the electric drill through a transmission shaft, an air inlet of the exhaust fan is connected to an exhaust pipe, and the exhaust pipe is connected to the material receiving hopper.

[0008] The mounting seat is a connection structure that can be detachably fixed to the electric drill body, and can be in the form of a clamp, or an interface can be reserved on the electric drill to cooperate with the mounting group.

[0009] The support arm itself is a telescopic arm with adjustable length, because when the electric drill is working, the receiving hopper should always be located on the wall and the position is relatively fixed. However, as the electric drill is drilling, the electric drill body will move toward the wall, so it is necessary to change the distance between the receiving hopper and the mounting seat, and the telescopic arm has an elastic force extending outward, that is, the telescopic arm will naturally extend without being driven by external force. Preferably, the spring can be used to extend the telescopic arm. The elastic force of the telescopic arm can keep the receiving hopper pressed against the wall.

[0010] Preferably, the support arm is a telescopic rod structure, a spring is arranged on the support arm, and the spring is a compression spring, and the elastic force of the spring pushes the support arm to extend.

[0011] The air extraction pipe is a bellows, the length of which can be extended and retracted, and the air extraction pipe itself has the elasticity to contract inwards, so that the air extraction pipe can always be in a stretched state.

[0012] The exhaust fan has an air inlet and an air outlet, the air inlet is connected to an exhaust pipe, the exhaust pipe is connected to a material receiving hopper, and the material receiving hopper is the air inlet.

[0013] The air outlet of the exhaust fan points directly downward.

[0014] The air inlet of the air extraction pipe is arranged on the side wall of the receiving hopper. Because the debris will fall to the bottom of the receiving hopper, the air inlet of the air extraction pipe is arranged on the side wall of the receiving hopper to prevent the falling debris from blocking the air extraction pipe.

[0015] A filter is provided at the air inlet of the exhaust pipe, and the filter is detachably connected to the receiving hopper. The filter prevents debris from entering the exhaust fan on the one hand, and initially filters dust to reduce dust on the other hand. At the same time, in order to facilitate the replacement of the filter, the filter is detachably provided on the receiving hopper, that is, at the air inlet of the exhaust pipe.

[0016] The air inlet of the exhaust pipe is in a gradually expanding bell-mouth shape, and the filter is arranged at the opening of the bell-mouth. The filter will affect the ventilation volume to a certain extent, so the air inlet of the exhaust pipe is in a bell-mouth shape, which can expand the working area of ​​the filter and increase the air intake.

[0017] On the other hand, the present application provides a dustproof electric drill, including an electric drill body, and a dust suction assembly installed on the electric drill body, wherein the dust suction assembly is the electric drill dust suction assembly described above.

[0018] The beneficial effect brought about by the technical solution provided by the embodiment of the utility model is that the dust suction component is installed on the electric drill, and the material receiving hopper can be used to receive the debris dropped from the drill bit, and an exhaust fan is provided, the exhaust fan is connected to the material receiving hopper, and the dust is extracted from the material receiving hopper, and then discharged from the exhaust port of the exhaust fan, so that dust can be prevented from flying everywhere and affecting the construction of the operator.

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. Of course, the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] Embodiment 1:

[0025] See also Figure 1-Figure 2 The utility model provides an electric drill dust suction component, such as Figure 1 As shown, an electric drill dust suction assembly includes a mounting base 2a connected to an electric drill body 1, the mounting base 2a is connected to a support arm 2b, the support arm 2b can be extended along its length direction, and the end of the support arm 2b is provided with a hopper 2c;

[0026] The dust suction assembly 2 also includes an exhaust fan 2d, a fan of which is connected to the main shaft 1a of the electric drill via a transmission shaft 2e, an air inlet of the exhaust fan 2d is connected to an exhaust pipe 2f, and the exhaust pipe 2f is connected to a hopper 2c.

[0027] The mounting base 2a is a connection structure that can be detachably fixed to the electric drill body 1, which can be in the form of a clamp, or a reserved interface on the electric drill to cooperate with the mounting group. The support arm 2b itself is a telescopic arm with an adjustable length, because when the electric drill is working, the hopper 2c should always be located on the wall, and the position is relatively fixed, but as the electric drill is drilling, the electric drill body 1 will move toward the wall, so it is necessary to change the distance between the hopper 2c and the mounting base 2a.

[0028] The telescopic arm has an elastic force extending outward, that is, the telescopic arm will naturally extend without being driven by external force. Therefore, the telescopic arm can be extended by compressed gas, such as a cylinder.

[0029] Preferably, a spring 2h can be used, and the elastic force of the spring 2h can be used to extend the telescopic arm. The elastic force of the telescopic arm can keep the receiving hopper 2c pressed against the wall. Preferably, the support arm 2b is a telescopic rod structure, and a spring 2h is arranged on the support arm 2b. The spring 2h is a compression spring, and the elastic force of the spring 2h pushes the support arm 2b to extend.

[0030] Because the length of the support arm 2b may change, the air extraction pipe 2f is a bellows, and the length of the bellows can be extended and retracted. The air extraction pipe 2f itself has the elasticity to contract inwards, so that the air extraction pipe 2f can always be in a straight state.

[0031] The exhaust fan 2d is a blower or a fan with a duct, with an air inlet and an air outlet, and there is a fan inside the exhaust fan 2d. The air inlet of the exhaust fan 2d is connected to the exhaust pipe 2f, and the exhaust pipe 2f is connected to the hopper 2c, so that the hopper 2c acts as an air inlet. The position of the air outlet of the exhaust fan 2d can be adjusted according to actual conditions, and the preferred air outlet points directly downward to blow out the dust downward.

[0032] Because the debris will fall to the bottom of the receiving hopper 2c, the air inlet of the exhaust pipe 2f is arranged on the side wall of the receiving hopper 2c to prevent the fallen debris from blocking the exhaust pipe 2f.

[0033] In addition, a filter 2g is provided at the air inlet of the exhaust pipe 2f, and the filter 2g is detachably connected to the receiving hopper 2c. The filter 2g prevents debris from entering the exhaust fan 2d on the one hand, and initially filters dust to reduce dust on the other hand. At the same time, in order to facilitate the replacement of the filter 2g, the filter 2g is detachably provided on the receiving hopper 2c, that is, at the air inlet of the exhaust pipe 2f.

[0034] The air inlet of the exhaust pipe 2f is in a gradually expanding bell-shaped shape, and the filter 2g is arranged at the opening of the bell-shaped shape. Because the filter 2g will affect the ventilation volume to a certain extent, the air inlet of the exhaust pipe 2f is in a bell-shaped shape, which can expand the working area of ​​the filter 2g and increase the air intake volume.

[0035] Because the filter 2g is provided, the wind pressure loss at the air inlet end will be relatively large, so the fan of the vacuum pump is a centrifugal fan. A centrifugal fan can provide a higher wind pressure.

[0038] like Figure 2 As shown in the figure, the dust suction assembly 2 is detachably connected to the electric drill body 1. Specifically, it includes two parts. On the one hand, the mounting seat 2a is detachably connected to the electric drill body 1. It has been explained above, so it will not be explained again.

[0039] On the other hand, the transmission shaft 2e and the electric drill body 1 also need to be detachably connected. Specifically, the transmission shaft 2e includes an inner transmission shaft 2e disposed inside the electric drill body 1 and an outer transmission shaft 2e disposed outside the electric drill body 1 and connected to the exhaust fan 2d, and the inner transmission shaft 2e and the outer transmission shaft 2e are detachably connected;

[0040] The shell of the inner electric drill body 1 is provided with a through hole for the transmission shaft 2e to pass through, one end of the inner transmission shaft 2e is located at the through hole, and the other end is connected to the main shaft 1a of the electric drill body 1. That is, the inner transmission shaft 2e is pre-arranged on the electric drill body 1, and a connection interface is reserved on the shell, such as a spline or a coupling, and then the outer transmission shaft 2e is connected to the inner transmission shaft 2e.

[0041] The air outlet of the exhaust fan 2d is provided with an air outlet pipe, and the nozzle direction of the air outlet pipe is adjustable. The air outlet pipe can be arranged at a suitable position according to the actual construction situation.

[0042] The preferred embodiments of the present invention are described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.
