Description

Technical Field

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

[0002] A power drill with a dust-collecting function is an electric tool that combines the drilling and tightening functions of a drill with a dust-collecting function. It is usually equipped with a special dust-collecting device, such as a dust hood or dust-collecting pipe, on the drill body. When the drill is working, it can collect the dust and debris generated during the drilling process in a timely manner, preventing dust from flying around and keeping the working environment clean. At the same time, it also helps to reduce the impact of dust on the health of operators and improves the safety and comfort of the work.

[0003] For example, the Chinese authorized patent CN213889876U, entitled "A Hand Drill with Dust Collection Function," includes a motor, a first handle fixedly connected to the right side of the motor's bottom, a dust collection box fixedly connected to the left side of the motor's bottom, a dust collection screen extending through the bottom left side of the dust collection box, an air vent at the bottom of the dust collection box, and a guide plate fixedly connected to the right side of the top of the motor's inner cavity, with the bottom of the guide plate contacting the top of the dust collection screen. This utility model utilizes the combined use of a dust collection box, a dust collection screen, an air vent, a guide plate, a fan, a fixed block, a movable rod, a movable block, a spring, a dust cover, a dust collection hood, and a controller.

[0004] While the existing technologies can achieve dust adsorption during drilling, the main body of the dust-collecting structure on the electric drill increases the overall weight, further accelerating the fatigue of the user's arm. Moreover, in order to control the size, the motor generally uses low power, resulting in poor dust collection effect. Therefore, it does not meet the current needs. In this regard, we propose an electric drill with dust collection function. Utility Model Content

[0005] The purpose of this invention is to provide an electric drill with a dust-collecting function to solve the problems mentioned in the background art, such as electric drills with a dust-collecting function causing user arm fatigue and poor dust-collecting effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric drill with a dust collection function, comprising an electric drill body, a first dust baffle plate installed at the front end of the drill bit of the electric drill body, and the first dust baffle plate being inserted and fixed to the outer shell of the electric drill body, a movable second dust baffle plate installed at the front end of the first dust baffle plate, a dust collection port provided inside the first dust baffle plate, a dust collection hose installed at the lower end of the dust collection port, a dust collection cylinder provided at the other end of the dust collection hose, a negative pressure fan fixedly installed at the upper end of the dust collection cylinder, an adsorption tube provided at the lower end of the negative pressure fan, and the adsorption tube extending into the interior of the dust collection cylinder, a dust inlet pipe installed at the lower end of the adsorption pipe, and a groove provided at one end of the dust inlet pipe inside the dust collection cylinder.

[0007] Preferably, the first dust baffle has a movable groove inside, one end of the second dust baffle extends into the movable groove, and the movable groove and the second dust baffle are slidably limited, and a return spring is installed between one end of the second dust baffle and the movable groove.

[0008] Preferably, the first dust baffle and the second dust baffle are inclined upwards, and the second dust baffle is longer than the drill bit of the electric drill body before being subjected to stress.

[0009] Preferably, a belt is installed on one side of the vacuum cleaner, and the vacuum cleaner is attached to the belt.

[0010] Preferably, a movable cylinder is installed inside the vacuum cleaner, and the movable cylinder is slidably connected to the vacuum cleaner. The top of the movable cylinder is provided with a round hole, which is wrapped around the adsorption tube. A rubber ring is provided at the round hole at the top of the movable cylinder. A filter screen is provided on the outer wall of the adsorption tube. During the vertical movement of the movable cylinder, the rubber ring and the filter screen are in contact. An inner convex ring is integrally formed at the lower end of the movable cylinder.

[0011] Preferably, a sealing cap is installed at the bottom of the vacuum cleaner, and the sealing cap is fastened to the vacuum cleaner.

[0012] Preferably, the upper end of the dust inlet pipe is connected to the adsorption pipe by a thread, and the lower end of the dust inlet pipe is inserted and fixed to the adsorption pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model features a dust baffle plate positioned below the drill bit. This arc-shaped dust baffle plate does not obstruct the upper part of the drill bit, allowing the user to easily observe the drilling position and accurately drill. During use, the first dust baffle plate will initially contact the wall. As the drill bit approaches the drilling position, the first dust baffle plate will extend into the movable groove. Simultaneously, supported by a return spring, it ensures that the front end of the first dust baffle plate is tightly attached to the wall. During drilling, some dust will fall into the dust baffle plate. Due to the inclined structure of the dust baffle plate, coupled with the high-frequency vibration generated during the operation of the electric drill, the dust inside the dust baffle plate can be guided to the inside of the suction port. Combined with the negative pressure generated by the suction port, dust can be quickly adsorbed.

[0015] 2. This utility model features a convenient and easy-to-clean vacuum cleaner. By activating the negative pressure fan, the internal air is quickly expelled, while external air continuously enters the negative pressure fan through the vacuum hose, creating a high pressure difference with the outside. Dust outside the vacuum port enters the dust inlet pipe through the vacuum hose and then enters the movable cylinder through the slot of the dust inlet pipe. After using the electric drill, to expel the dust, the sealing cap needs to be pulled down to separate from the vacuum cleaner. Then, the user holds the inner convex ring and pulls the movable cylinder down. On the one hand, the internal dust is brought out during the descent, and on the other hand, the rubber ring at the upper end can connect with the filter screen on the outer wall of the adsorption tube to separate the residual dust on the surface, ensuring the vacuuming effect every time.

[0016] 3. This utility model separates the negative pressure fan and the dust collection cylinder from the main body of the electric drill. The dust collection cylinder containing the negative pressure fan is installed on the waist belt. During use, the operator can fix the belt around their waist, eliminating the need for additional load on the arm and greatly relieving arm pressure. This effectively reduces fatigue, making long-term work possible and significantly improving work efficiency. By independently placing the negative pressure fan inside the dust collection cylinder, a more powerful fan can be selected to generate stronger suction and more efficiently absorb dust generated during drilling, maintaining a clean working environment and reducing the health hazards of dust to operators.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 An embodiment of this utility model provides: an electric drill with a dust suction function, including an electric drill body 1, a first dust baffle 7 installed at the front end of the drill bit of the electric drill body 1, and the first dust baffle 7 is inserted and fixed to the outer shell of the electric drill body 1, a movable second dust baffle 8 is installed at the front end of the first dust baffle 7, a dust suction port 9 is provided inside the first dust baffle 7, a dust suction hose 2 is installed at the lower end of the dust suction port 9, a dust suction cylinder 3 is provided at the other end of the dust suction hose 2, a negative pressure fan 4 is fixedly installed at the upper end of the dust suction cylinder 3, an adsorption tube 12 is provided at the lower end of the negative pressure fan 4, and the adsorption tube 12 extends into the interior of the dust suction cylinder 3, a dust inlet pipe 14 is installed at the lower end of the adsorption tube 12, and a groove 15 is provided at one end of the dust inlet pipe 14 located inside the dust suction cylinder 3;

[0024] By starting the negative pressure fan 4, the internal air is quickly discharged. At the same time, the external air of the suction port 9 is continuously replenished into the negative pressure fan 4 through the suction hose 2, forming a high pressure difference with the outside. Then, the dust outside the suction port 9 enters the dust inlet pipe 14 through the suction hose 2, and then enters the movable cylinder 16 from the slot 15 of the dust inlet pipe 14.

[0025] Please see Figure 2 and Figure 3 The first dust baffle 7 has a movable groove 10 inside, one end of the second dust baffle 8 extends into the movable groove 10, and the movable groove 10 and the second dust baffle 8 are slidably limited. A return spring 11 is installed between one end of the second dust baffle 8 and the movable groove 10.

[0026] The dust baffle has an arc-shaped structure, which does not obstruct the top of the drill bit, making it easier for the user to observe the drilling position and drill accurately. During use, the second dust baffle 8 will first contact the wall. As the drill bit approaches the drilling position, the second dust baffle 8 will extend into the interior of the movable groove 10. At the same time, with the support of the return spring 11, it can be ensured that the front end of the second dust baffle 8 is in close contact with the wall. During the drilling process, some dust will fall into the dust baffle. Due to the inclined structure of the dust baffle, coupled with the high-frequency vibration generated during the operation of the electric drill, the dust inside the dust baffle can be guided to the interior of the suction port 9. With the negative pressure generated by the suction port 9, the dust can be quickly adsorbed.

[0027] Please see Figure 1 A belt 6 is installed on one side of the vacuum cleaner 3, and the vacuum cleaner 3 and the belt 6 are connected. The operator only needs to fix the belt 6 around their waist to move freely during operation, without being restricted by the position of the vacuum cleaner structure. This allows for more flexible operation of the electric drill and adaptability to various complex work scenarios. This design enables operators to easily achieve the vacuuming function when working in special environments such as high places or narrow spaces, greatly expanding the application range of the electric drill.

[0028] Please see Figure 4 The vacuum cleaner 3 has a movable cylinder 16 installed inside, which is slidably connected to the vacuum cleaner 3. The top of the movable cylinder 16 has a round hole that surrounds the suction tube 12. A rubber ring 17 is located at the round hole at the top of the movable cylinder 16. A filter screen 13 is installed on the outer wall of the suction tube 12, and the rubber ring 17 and the filter screen 13 are in contact during the vertical movement of the movable cylinder 16. An inner convex ring 18 is integrally formed at the lower end of the movable cylinder 16. A sealing cap 5 is installed at the bottom of the vacuum cleaner 3, and the sealing cap 5 is fastened to the vacuum cleaner 3, preventing dust from entering. The upper end of tube 14 is connected to adsorption tube 12 by a thread, and the lower end of dust inlet tube 14 is inserted and fixed to adsorption tube 12. After the electric drill is used, when the dust is discharged, the sealing cover 5 needs to be pulled down to separate from the dust collection tube 3. Then the user holds the inner convex ring 18 with his hand and pulls the movable tube 16 down. On the one hand, the dust inside is brought out during the descent, and on the other hand, the rubber ring 17 set at its upper end can connect with the filter screen 13 on the outer wall of adsorption tube 12 to separate the dust remaining on the surface, ensuring the dust collection effect every time.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
