Problems solved by technology
[0002] When the electric tool is in use, it is mainly driven by a motor. The motor is installed inside the electric tool casing, and the air outlet is provided on the casing in the circumferential direction of the motor position, which is mainly used for air exchange inside and outside the electric tool casing, so that the electric tool The heat is dissipated during use to prevent the motor from being damaged due to overheating, but there are certain problems in the above structure. Although the setting of the air outlet plays a role in heat dissipation, it also makes it easy for the dust on the outside of the housing to enter the inside of the housing through the air outlet. When the dust accumulates too much in the casing, it is easy to cause damage to the electric tool, affect its performance, and reduce the service life of the electric tool

Embodiment Construction
[0020] Such as Figure 1-4 As shown, a power tool with heat dissipation function includes a housing 1, a motor is arranged in the housing 1, and several cooling holes 2 are opened on the housing 1 at corresponding positions of the motor. The housing 1 Covered with a movable cover 3 matching the shape of the rear end of the housing 1 and the handle portion 17, the movable cover 3 is elastically matched with the housing 1 and can move elastically relative to the housing 1. The movable cover 3 is provided with cooling holes 2 Auxiliary holes 4 matching in shape and quantity. In the natural state, the cooling holes 2 and the auxiliary holes 4 are staggered back and forth, and the cooling holes 2 are closed; Exchange cooling.
[0021] In the present invention, by setting the movable cover 3 matching the shape of the rear end of the housing 1 and the handle part 17, when the electric tool is in use, the user can push the movable cover 3 toward the head of the electric tool by holdi...

The invention relates to an electric tool with a heat dissipation function. The electric tool comprises a shell, a motor is arranged in the shell, a plurality of heat dissipation holes are formed in the positions, corresponding to the motor, of the shell, the shell is wrapped with a movable cover matched with the back end of the shell and a handle part in shape, the movable cover elastically cooperates with the shell and can elastically move relative to the shell, and the movable cover is provided with auxiliary holes matched with the heat dissipation holes in shape and number; in the naturalstate, the heat dissipation holes and the auxiliary holes are staggered back and forth, and the heat dissipation holes are closed; and in the use state, the heat dissipation holes communicate with theauxiliary holes to allow air inside and outside the shell to achieve exchange heat dissipation. The electric tool is provided with the movable cover matched with the rear end of the shell and the handle part in shape, when the electric tool is used, a user holds the handle part with the hand, the movable cover is pushed in the direction of the head of the electric tool, and the auxiliary holes inthe movable cover communicate the heat dissipation holes in the shell to achieve heat dissipation; and when the electric tool is not used, the movable cover elastically resets, and dust is preventedfrom entering the shell.
