Description

Technical Field

[0001] This utility model relates to the field of angle grinder technology, and in particular to a dust-collecting angle grinder. Background Technology

[0002] An angle grinder, also known as a grinding machine or disc grinder, is an abrasive tool used for cutting and polishing fiberglass. It is a handheld power tool primarily used for cutting, grinding, and brushing metals and stone.

[0003] For example, Chinese utility model patent (CN215036317U) discloses an angle grinder that facilitates dust collection. It states: "In this utility model, by threading a dust collection cylinder to the rear of the control cylinder, and providing a baffle on the outer side of the grinding wheel with a dust collection port inside the baffle, a pump can draw dust and debris generated by the grinding wheel into the dust collection cylinder. Then, the dust collection cylinder can be disassembled, and the internal impurities can be poured out, saving time and effort." It also states: "Existing angle grinders generally suffer from defects such as difficulty in collecting the dust generated during grinding, and difficulty in processing the collected dust. Furthermore, each angle grinder can only be fitted with a single type of grinding wheel, resulting in a low range of applicability."

[0004] In summary, existing technologies involve rotating the dust collection cylinder from the rear of the control cylinder after use, removing the rear cover, and emptying the internal impurities. However, this method has the following technical problems: during the disassembly of the dust collection cylinder after use, the rotation of the dust collection cylinder pulls on the flexible hose, which can easily damage the connection between the flexible hose and the dust collection cylinder. Furthermore, the dust collection cylinder needs to be rotated multiple times during installation or disassembly, which is cumbersome and reduces the efficiency of cleaning the dust collection cylinder. Therefore, this application proposes a dust collection angle grinder to solve the technical problems mentioned in the above patent and provide a new technical solution. Utility Model Content

[0005] Based on this, it is necessary to address the aforementioned technical problems by providing a dust collection angle grinder. By pulling two pull rings in a direction away from each other, multiple insert rods can be disengaged from the dust collection box. Subsequently, the dust collection box can be pulled, moving it along the direction of the central axis of the connecting pipe, thereby separating the connecting pipe from the dust collection box. This reduces twisting between components during dust collection box insertion, thus decreasing wear and tear and lowering the frequency of device maintenance. Furthermore, disassembling the dust collection box only requires pulling the pull rings to both sides, a simple process that reduces the time required for disassembling the dust collection box, thereby improving the efficiency of subsequent maintenance operations involving dust collection box disassembly and enhancing the practicality of the device.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A dust-collecting angle grinder, which is used in angle grinders.

[0008] The dust-collecting angle grinder specifically includes:

[0009] An angle grinder body, a protective cover is fixedly installed on the outer wall of the angle grinder body, a dust collection mechanism is provided on the angle grinder body, and a drive mechanism is provided on the dust collection mechanism;

[0010] The dust collection mechanism includes a connecting box, a fixed base, a dust inlet component, a collection component, and an installation component. The connecting box is fixedly connected to the outer wall of the protective cover, and the fixed base is fixedly connected to the outer wall of the angle grinder body. Installation components are respectively provided on the front and rear sides of the fixed base.

[0011] In a preferred embodiment of the dust collection angle grinder provided by this utility model, the dust inlet assembly includes a dust inlet pipe, and multiple dust inlet pipes are fixedly connected to the inner wall of the connecting box.

[0013] In a preferred embodiment of the dust-collecting angle grinder provided by this utility model, the mounting assembly includes a rectangular rod. The rectangular rod is slidably connected to the inner wall of the fixed base, and a sliding plate is fixedly connected to the outer wall of the rectangular rod. The sliding plate is slidably connected to the inner wall of the fixed base. A spring is sleeved on the outside of the rectangular rod, and the two ends of the spring are respectively fixedly connected to the inner wall of the fixed base and the outer wall of the sliding plate. A pull ring is fixedly connected to the outer wall of the rectangular rod, and a connecting plate is fixedly connected to the outer wall of the rectangular rod. Multiple insertion rods are fixedly connected to the outer wall of the connecting plate, and the multiple insertion rods are movably inserted into the dust collection box.

[0014] In a preferred embodiment of the dust-collecting angle grinder provided by this utility model, the driving mechanism includes an installation tube, the outer wall of the dust collection box is detachably installed with the installation tube by means of threads, and the inner wall of the installation tube is fixedly connected with a dustproof net.

[0015] In a preferred embodiment of the dust-collecting angle grinder provided by this utility model, the drive mechanism further includes a protective shell, which is detachably installed on the inner wall of the mounting tube by means of threads. A fan is fixedly installed on the inner wall of the protective shell, and a protective net is detachably connected to the end of the protective shell away from the mounting tube by means of bolts.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The dust collection angle grinder provided by this utility model allows multiple insertion rods to be disengaged from the dust collection box by pulling two pull rings in a direction away from each other. Subsequently, the dust collection box can be pulled to move along the direction of the central axis of the connecting pipe, thereby separating the connecting pipe from the dust collection box.

Furthermore, the dust collection box can be disassembled simply by pulling the pull rings on both sides, which is a simple process and reduces the time required to disassemble the dust collection box. This improves the efficiency of subsequent maintenance operations that require disassembly of the dust collection box and enhances the practicality of the device.

[0018] The dust-collecting angle grinder provided by this utility model uses a fan to drive airflow, allowing small particles generated during the grinder's operation to enter the dust inlet pipe with the air, and then move to the dust collection box through the connecting pipe. This reduces the amount of dust around the grinder during operation. The dustproof net reduces dust adhesion to the outside of the fan, which can increase wear between the fan components and reduce its heat dissipation during operation. By rotating the mounting pipe, the mounting pipe can be separated from the dust collection box, making it easy to empty the dust inside the dust collection box. The simple operation improves the convenience of the device. Attached Figure Description

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0028] As described in the background art, however, during the disassembly of the dust collection cylinder after use, the rotation of the dust collection cylinder will pull the elastic hose, which may cause damage to the connection between the elastic hose and the dust collection cylinder. Furthermore, the dust collection cylinder needs to be rotated multiple times during installation or disassembly, which is a troublesome process and reduces the efficiency of cleaning the dust collection cylinder.

[0029] To solve this technical problem, this utility model provides a dust-collecting angle grinder, which is applied to angle grinders.

[0030] For details, please refer to Figures 1-2 The dust collection angle grinder specifically includes:

[0031] An angle grinder body 1, a protective cover 2 is fixedly installed on the outer wall of the angle grinder body 1, a dust collection mechanism 3 is provided on the angle grinder body 1, and a drive mechanism 4 is provided on the dust collection mechanism 3;

[0032] The dust collection mechanism 3 includes a connecting box 20, a fixed base 7, a dust inlet component, a collection component, and an installation component. The connecting box 20 is fixedly connected to the outer wall of the protective cover 2, and the fixed base 7 is fixedly connected to the outer wall of the angle grinder body 1. Installation components are respectively provided on the front and rear sides of the fixed base 7.

[0033] The angle grinder body 1 in this application has the same specific structure and working principle as the control cylinder, cover plate, connecting wire, heat dissipation hole, control terminal, drive rod, lighting lamp, grinding wheel, connecting rod, switch, motor and controller combination of the prior art mentioned in the background art. It belongs to the prior art, so it will not be described in detail.

[0034] The dust collection angle grinder provided by this utility model allows multiple insertion rods 14 to be disengaged from the dust collection box 8 by pulling two pull rings 12 in a direction away from each other. Subsequently, the dust collection box 8 can be pulled to move along the direction of the central axis of the connecting pipe 6, thereby separating the connecting pipe 6 from the dust collection box 8. When inserting the dust collection box 8, there is less twisting between the components, which reduces wear between the components and lowers the frequency of device maintenance. Furthermore, when disassembling the dust collection box 8, it is only necessary to pull the pull rings 12 to both sides. This process is relatively simple, reduces the time required to disassemble the dust collection box 8, and thus improves the efficiency of subsequent maintenance operations involving the disassembly of the dust collection box 8, thereby improving the practicality of the device.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Example 1

[0036] Please refer to Figures 1-4 A dust-collecting angle grinder, comprising:

[0037] An angle grinder body 1, a protective cover 2 is fixedly installed on the outer wall of the angle grinder body 1, a dust collection mechanism 3 is provided on the angle grinder body 1, and a drive mechanism 4 is provided on the dust collection mechanism 3;

[0038] The dust collection mechanism 3 includes a connecting box 20, a fixed base 7, a dust inlet component, a collection component, and an installation component. The connecting box 20 is fixedly connected to the outer wall of the protective cover 2, and the fixed base 7 is fixedly connected to the outer wall of the angle grinder body 1. Installation components are respectively provided on the front and rear sides of the fixed base 7. The dust collection mechanism 3 provides a space for collecting dust around the angle grinder body 1 when it is working.

[0039] The dust inlet assembly includes a dust inlet pipe 21. Multiple dust inlet pipes 21 are fixedly connected to the inner wall of the connecting box 20. All multiple dust inlet pipes 21 are fixedly connected to the inner wall of the protective cover 2. The ends of the multiple dust inlet pipes 21 away from the connecting box 20 are detachably connected to an anti-clogging mesh 5 by bolts. The dust inlet assembly can guide the dust around the angle grinder body 1 into the connecting pipe 6 when the air flows. The anti-clogging mesh 5 can reduce the entry of larger small particles into the dust inlet pipe 21 and reduce the blockage of the internal channels of the device. The connecting box 20 is a hollow structure.

[0040] The collection assembly includes a connecting pipe 6, which is detachably connected to the inner wall of the connecting box 20 via threads. A dust collection box 8 is movably inserted into the fixing seat 7. The end of the connecting pipe 6 away from the connecting box 20 passes through the fixing seat 7 and is movably inserted into the dust collection box 8. The collection assembly can guide the dust carried by the dust airflow into the dust collection box 8. The connecting pipe 6 passes through the fixing seat 7 and is threaded into the connecting box 20, which is convenient for the operator to remove the connecting pipe 6 later. Since the connecting pipe 6 is a straight rod, it is convenient for the operator to clear the inside of the connecting pipe 6 later. A rubber ring is fixedly installed on the inner wall of the hole on the dust collection box 8 for the connecting pipe 6 to be inserted into the dust collection box 8, so that when the air flows, the leakage of air between the connecting pipe 6 and the dust collection box 8 is reduced.

[0041] The mounting assembly includes a rectangular rod 9, which is slidably connected to the inner wall of the fixed base 7. A sliding piece 10 is fixedly connected to the outer wall of the rectangular rod 9, and the sliding piece 10 is slidably connected to the inner wall of the fixed base 7. A spring 11 is sleeved on the outside of the rectangular rod 9, and the two ends of the spring 11 are fixedly connected to the inner wall of the fixed base 7 and the outer wall of the sliding piece 10, respectively. A pull ring 12 is fixedly connected to the outer wall of the rectangular rod 9, and a connecting plate 13 is fixedly connected to the outer wall of the connecting plate 13. Multiple insertion rods 14 are fixedly connected to the outer wall of the connecting plate 13, and the multiple insertion rods 14 are movably inserted into the dust collection box 8. The mounting assembly makes it convenient for the operator to install the dust collection box 8 on the fixed base 7.

[0042] With the above structural design, when the operator controls the angle grinder body 1 to work, the drive mechanism 4 can be activated to drive airflow, allowing air to pass through the anti-clogging net 5 into the dust inlet pipe 21, then through the connecting box 20 into the connecting pipe 6, then into the dust collection box 8, and finally into the drive mechanism 4 to flow to the outside. During the airflow, suitable small particles around the working position of the angle grinder body 1 can be driven through the anti-clogging net 5 into the dust inlet pipe 21, then through the connecting box 20 into the connecting pipe 6, and finally into the dust collection box 8 for collection. When the dust collection box 8 needs to be disassembled for cleaning, the operator can pull the two pull rings 12 in a direction away from each other, causing the two rectangular rods 9 to slide in a direction away from each other on the inner wall of the fixed seat 7, causing the spring 11 to deform accordingly, thereby causing multiple insert rods 14 to leave the dust collection box 8. Then the dust collection box 8 can be pulled, causing the dust collection box 8 to move along the direction of the central axis of the connecting pipe 6. The connecting pipe 6 can be moved to separate it from the dust collection box 8, allowing for cleaning of the inside of the dust collection box 8. If the connecting pipe 6 needs to be unblocked, it can be rotated relative to the connecting box 20 to separate it from the box. The connecting pipe 6 can then be removed by passing through the fixing seat 7. A rod with a cross-sectional diameter smaller than the inner diameter of the connecting pipe 6 can then be used to unblock the inside of the connecting pipe 6. The connecting pipe 6 can then be threaded through the fixing seat 7 and installed on the outside of the connecting box 20. The cleaned dust collection box 8 can then be installed by pulling the pull rings 12 to both sides until the insertion rod 14 moves into the fixing seat 7. The dust collection box 8 is then inserted into the fixing seat 7 along the direction of the central axis of the connecting pipe 6. At this time, the end of the connecting pipe 6 located in the fixing seat 7 is also inserted into the dust collection box 8. Then, the two pull rings 12 are released, and the two connecting discs 13 move closer to each other under the action of the two springs 11, allowing multiple insertion rods 14 to be inserted into the dust collection box 8. Example 2

[0043] The dust-collecting angle grinder provided in Example 1 has been further optimized, specifically, as follows: Figure 5 As shown, the drive mechanism 4 includes an installation tube 15. The installation tube 15 is detachably installed on the outer wall of the dust collection box 8 via threads. A dustproof net 16 is fixedly connected to the inner wall of the installation tube 15. The dustproof net 16 can block small particles inhaled into the dust collection box 8 and part of the installation tube 15, reducing the adhesion of small particles to the fan 18. The aperture of the holes on the dustproof net 16 is smaller than the aperture of the holes on the anti-clogging net 5.

[0044] The drive mechanism 4 also includes a protective shell 17, which is detachably installed on the inner wall of the mounting pipe 15 by means of threads. A fan 18 is fixedly installed on the inner wall of the protective shell 17. A protective net 19 is detachably connected to the end of the protective shell 17 away from the mounting pipe 15 by means of bolts. The fan 18 can drive the air to flow, so that the outside air passes through the dust inlet pipe 21, the connecting box 20, the connecting pipe 6, the dust collection box 8, the mounting pipe 15, and the protective shell 17 in sequence, and finally flows to the outside.

[0045] With the above structural design, when it is necessary to simply clean the dust inside the dust collection box 8, the mounting tube 15 can be rotated to separate the mounting tube 15 from the dust collection box 8, thereby emptying the small particles inside the dust collection box 8. When it is necessary to clean the inside of the dust collection box 8 more thoroughly, the dust collection box 8 can be disassembled for cleaning. At the same time, the protective shell 17 can be rotated to separate the protective shell 17 from the mounting tube 15. At this time, the mounting tube 15 can be cleaned to reduce the situation where small particles clog the holes on the dustproof net 16, thereby increasing the obstruction of air passing through the dustproof net 16.
