Abstract

The invention relates to the field of electric tools and discloses a protective cover device and an angle grinder. The protective cover device comprises a protective cover, a first identification unit, a body sensing unit, a first wireless communication unit and a control unit, wherein the first identification unit and the body sensing unit are arranged on the protective cover; the first identification unit is used for being identified by the angle grinder so that the angle grinder can determine that the protective cover is accurately mounted on the angle grinder; the body sensing unit is usedfor sensing whether body biological signals exist within a preset operational range of the grinding wheel of the angle grinder; the control unit is connected with the body sensing unit and the firstwireless communication unit and used for generating an alarming signal when the body sensing unit senses the body biological signals within the preset operational range of the grinding wheel of the angle grinder and controlling the first wireless communication unit to transmit the alarming signal to the angle grinder. Therefore, the protective cover device and the angle grinder can achieve motor braking control, safe alarming and intelligent safety protection of the angle grinder.

Description

technical field [0001] The embodiments of the present invention relate to the field of electric tools, in particular to a protective cover device and an angle grinder. Background technique [0002] Angle grinder, also known as grinder or disc grinder, is a kind of abrasive tool used for cutting and grinding FRP. Angle grinder is a portable electric tool that uses fiberglass to cut and grind. It is mainly used for cutting, grinding or brushing metal and stone. Since the angle grinder is easy to cause personal safety injury to the user, the importance of the protective cover is self-evident. [0003] In the prior art, most angle grinders are not equipped with safety shields, and some angle grinders are provided with safety shields that are useless, and most users do not install or correctly use the shields according to the regulations, resulting in frequent accidents. Moreover, when the human body is close to the grinding wheel of the angle grinder, the motor has no brake co...
