Description

Technical Field

[0001] This utility model relates to the field of angle grinder technology, and in particular to an angle grinder with a dust collection function. Background Technology

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

[0003] When existing angle grinders are working, the grinding wheel grinds or cuts the material. During grinding or cutting, the grinding wheel easily generates a lot of dust and fumes. If this dust is not effectively collected, it will cause a decline in the air quality of the working environment and affect the health of workers. Moreover, if the dust is not collected in time, it may enter the inside of the angle grinder and damage it. Such angle grinders usually cannot collect the dust generated during grinding in time, which can easily affect the use of the angle grinder. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide an angle grinder with a dust collection function. Through a conveying pipe connected to the casing, when the air pump is started, the dust and fumes generated during the use of the angle grinder can be drawn into the dust collection box for storage. Angle grinders generate a large amount of dust and fumes during use. If this dust is not effectively collected, it will cause a decline in air quality in the working environment, affecting the health of workers. The dust collection function can effectively draw this dust into the dust collection box, reducing the dust concentration in the air and improving the working environment. A heat-conducting plate absorbs the temperature generated by the motor, and then the air inside the fan casing is cooled by a cooling plate and blown by fan blades onto the heat-conducting plate, thereby cooling the heat-conducting plate and the motor. The angle grinder motor generates high temperatures during long-term high-load operation. If the temperature is too high, it may affect the motor's performance and lifespan. By absorbing and dispersing heat through the heat-conducting plate, and then cooling it through the cooling plate and the air inside the fan casing, the operating temperature of the motor can be effectively controlled, extending its service life.

[0005] This utility model also provides an angle grinder with the aforementioned dust collection function, comprising: a body, a motor fixedly connected to the front surface of the body, a cutting tool fixedly connected to the output end of the motor, a protective shell fixedly connected to the lower surface of the body, the cutting tool located inside the protective shell, a dust collection box fixedly connected to the lower surface of the body, a conveying pipe connected to the side surface of the protective shell, the other end of the conveying pipe connected to the dust collection box, two baffles fixedly connected to the inner surface of the dust collection box, the two baffles being staggered vertically, and a...

[0012] Beneficial effects

[0013] 1. Compared with existing technologies, this angle grinder with dust collection function, through the conveying pipe connected to the protective shell, can draw the dust and smoke generated during the use of the angle grinder into the dust collection box for storage when the air pump is started. The angle grinder generates a large amount of dust and smoke during use. If this dust is not effectively collected, it will cause a decline in the air quality in the working environment and affect the health of workers. The dust collection function can effectively draw this dust into the dust collection box, reduce the dust concentration in the air, and improve the working environment.

[0014] 2. Compared with existing technologies, this angle grinder with dust collection function can absorb the temperature generated by the motor through the heat-conducting plate. Then, the air inside the fan housing is cooled by the cooling plate and blown by the fan blades to the heat-conducting plate, thereby cooling the heat-conducting plate and the motor. The angle grinder motor will generate a high temperature when operating under high load for a long time. If the temperature is too high, it may affect the performance and life of the motor. By absorbing and dispersing heat through the heat-conducting plate, and then cooling it through the cooling plate and the air inside the fan housing, the operating temperature of the motor can be effectively controlled, and its service life can be extended.
