Technical Field
[0001] This utility model relates to the technical field of debris collection devices, specifically a debris collection device for an angle grinder. Background Technology
[0002] An angle grinder, also known as a grinding wheel grinder or sander, is a power tool used for grinding, polishing, and finishing materials such as metal, stone, and glass. It typically uses a high-speed rotating grinding wheel or disc to process workpieces, performing operations such as surface grinding, cutting, lapping, and polishing. An angle grinder is often equipped with a chip collection device to collect debris during use.
[0003] Utility model patent CN215281343U discloses an angle grinder for corrosion-resistant and heat-insulating engineering. The grinder includes a main body, a collection cover fixedly connected to the bottom of the main body, a housing on the right side of the main body, a fixing plate fixedly connected to the top of the inner cavity of the housing, a drain pipe connected to the bottom of the right side of the housing, a water inlet pipe connected to the top of the right side of the housing, and clean water inside the housing. This utility model, through the coordinated use of the angle grinder main body, collection cover, housing, fixing plate, drain pipe, water inlet pipe, clean water, collection mechanism, and filtration mechanism, solves the problem of existing angle grinders lacking a proper dust collection device, which easily leads to the inability to collect dust, polluting the surrounding environment and affecting the user's health. This angle grinder for corrosion-resistant and heat-insulating engineering has the advantage of dust collection, thus improving the practicality of the angle grinder to a certain extent.
[0004] In the aforementioned prior art, debris is collected by water adsorption. However, during collection, debris continuously accumulates and adheres to the water, making it difficult to clean. Furthermore, in continuous operation, excessive debris accumulation can negatively impact the collection and adsorption efficiency. Therefore, improvements are needed. Utility Model Content
[0005] The purpose of this invention is to provide a debris collection device for angle grinders, which solves the problem that debris in water is not easy to clean in time, thus affecting the debris collection effect.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a debris collection device for an angle grinder, comprising a housing, a cover plate slidably connected to the top of the housing, multiple evenly distributed moving wheels at the bottom of the housing, a collection pipe fixedly connected to the left end of the housing, an air pump fixedly installed at the bottom of the inner wall of the housing, a guide shroud at the top of the air pump, an exhaust pipe at the right end of the air pump, the exhaust pipe being fixedly connected to the housing, multiple filter plates slidably sleeved inside the housing, a connecting rod fixedly connected between adjacent filter plates, a vibration mechanism on the filter plates, and a connecting mechanism on the cover plate.
[0007] Preferably, the vibration mechanism includes a motor. The motor is fixedly connected to the right end of the housing, and the output end of the motor is rotatably connected to the housing. A rotating rod is fixedly connected to the left end of the motor output end, and the rotating rod is rotatably connected to the housing. A top block is fixedly connected to the top of the rotating rod, and a protrusion is contacted on the top of the top block. The protrusion is fixedly connected to one of the filter plates. A connecting rod is fixedly connected to the top of one of the filter plates. A first spring is provided on the outer side of the connecting rod, and a limit ring is threadedly connected to the outer side of the connecting rod. By designing the vibration mechanism, the filter plates can vibrate when filtering debris.
[0008] Preferably, one end of the first spring is fixedly connected to the filter plate, and the other end of the first spring contacts the cover plate. By designing the first spring, the force of the first spring can be applied to the filter plate.
[0009] Preferably, a sealing ring is slidably fitted onto the outer side of the connecting rod, and the sealing ring is fixedly connected to the cover plate. By designing the sealing ring, the connection between the connecting rod and the cover plate can be sealed.
[0010] Preferably, the connecting mechanism includes a fixed base, which is fixedly connected to the outer side of the housing. A rotating shaft is rotatably connected to the inside of the fixed base via a bearing. A rotating seat is fixedly connected to the top of the rotating shaft. The rotating seat is rotatably connected to the cover plate. A fixed rod is fixedly connected to the inside of the rotating seat. A second spring is provided on the outer side of the fixed rod. A slider is slidably connected to the outer side of the fixed rod. The slider is slidably connected to the rotating seat. A retaining ball is movably connected inside the slider. The retaining ball is movably connected to both the rotating seat and the cover plate. A push block is fixedly connected to the top of the rotating seat. This connecting mechanism facilitates the removal of the filter plate.
[0011] Preferably, one end of the second spring is fixedly connected to the slider, and the other end of the second spring is fixedly connected to the rotating seat. By designing the second spring, the force of the second spring can be applied to the slider.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model utilizes the design of an air pump, which can draw air from the inside of the housing to create a negative pressure state. This negative pressure is then used to draw air from the outside through the collection pipe to collect debris. Subsequently, the debris is filtered out by the filter plate, thus achieving the collection of debris. In conjunction with the motor-driven top block pressing against the protrusion and the elastic action of the first spring, the filter plate can vibrate to prevent clogging. Compared with the water adsorption method for collection, this method avoids the problem of excessive debris adsorbed in the water, which is inconvenient to clean in time and affects subsequent collection. It also avoids the problem of the fan being damaged by directly sucking debris.
[0014] 2. This utility model, through the design of the contact between the rotating seat and the cover plate, can limit the vertical movement of the cover plate and prevent it from detaching from the housing. The insertion of the locking ball into the cover plate can limit the rotating seat and prevent it from moving arbitrarily. When the push block is pushed to rotate the rotating seat, the locking ball can be separated from the cover plate, which facilitates the disassembly of the cover plate and filter plate as a whole and makes it easy to clean and maintain the filter plate.

The output end of the motor 81 is rotatably connected to the housing 1. A rotating rod 82 is fixedly connected to the left end of the output end of the motor 81. The rotating rod 82 is rotatably connected to the housing 1. A top block 83 is fixedly connected to the top of the rotating rod 82. A protrusion 84 contacts the top of the top block 83. The protrusion 84 is fixedly connected to one of the filter plates 7. A connecting rod 85 is fixedly connected to the top of one of the filter plates 7. A first spring 86 is provided on the outer side of the connecting rod 85. One end of the spring 86 is fixedly connected to the filter plate 7, and the other end of the first spring 86 contacts the cover plate 11. By designing the first spring 86, the force of the first spring 86 can be applied to the filter plate 7. A sealing ring 87 is slidably sleeved on the outside of the connecting rod 85. The sealing ring 87 is fixedly connected to the cover plate 11. By designing the sealing ring 87, the connection between the connecting rod 85 and the cover plate 11 can be sealed. A limit ring 88 is threadedly connected to the outside of the connecting rod 85. By designing the vibration mechanism 8, the filter plate 7 can vibrate when filtering debris.
[0023] Please see Figure 1 , Figure 4The connecting mechanism 9 includes a fixed seat 91, which is fixedly connected to the outside of the housing 1. A rotating shaft 92 is rotatably connected to the inside of the fixed seat 91 via a bearing. A rotating seat 93 is fixedly connected to the top of the rotating shaft 92. The rotating seat 93 is rotatably connected to the cover plate 11. A fixed rod 94 is fixedly connected to the inside of the rotating seat 93. A second spring 95 is provided on the outside of the fixed rod 94. One end of the second spring 95 is fixedly connected to the slider 96, and the other end of the second spring 95 is fixedly connected to the rotating seat 93. By designing the second spring 95, the force of the second spring 95 can act on the slider 96. The slider 96 is slidably connected to the outside of the fixed rod 94. The slider 96 is slidably connected to the rotating seat 93. A retaining ball 97 is movably connected inside the slider 96. The retaining ball 97 is movably connected to the rotating seat 93 and the cover plate 11 respectively. A push block 98 is fixedly connected to the top of the rotating seat 93. By designing the connecting mechanism 9, it is convenient to remove the filter plate 7.
[0024] The specific implementation process of this utility model is as follows: When in use, first connect the collection tube 3 to the angle grinder. The specific connection method has been disclosed in the utility model patent with patent authorization announcement number CN215281343U, and will not be repeated here.
[0025] Once the connection is complete, start the air pump 4. The air pump 4 draws air into the inside of the housing 1 through the guide shroud 5, creating a negative pressure inside the housing 1. Then, it can be drawn in through the collection pipe 3. The debris will be drawn into the housing 1 along with the air, and the debris can be filtered and collected by the filter plate 7.
[0026] During the filtration and collection process, motor 81 operates simultaneously. The output of motor 81 drives rotating rod 82 to rotate, which in turn drives top block 83 to rotate. The rotation of top block 83 presses against protrusion 84, which in turn causes filter plate 7 to move upward. Filter plate 7 then drives connecting rod 85 to move upward, and filter plate 7 presses against first spring 86. When top block 83 rotates and separates from protrusion 84, the elasticity of first spring 86 pushes filter plate 7 downward to reset. This achieves vibration-based anti-clogging of filter plate 7. Compared to collection by water adsorption, this avoids the problem of excessive adsorption of debris in the water, which makes timely cleaning difficult and affects subsequent collection.
[0027] When it is necessary to disassemble the filter plate 7, simply rotate the push block 98. The push block 98 drives the rotating seat 93 to rotate, and the rotating seat 93 drives the retaining ball 97 to rotate. The retaining ball 97 will rotate along the cover plate 11 and be squeezed upwards. The retaining ball 97 will drive the slider 96 to slide along the fixed rod 94 and squeeze the second spring 95, which can separate the retaining ball 97 from the cover plate 11. Then, the cover plate 11 can be moved up to remove the entire structure of the filter plate 7 from the inside of the housing 1, which is convenient for cleaning and maintenance of the filter plate 7.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
