EXAMPLE six

Referring to fig. 11, in the present embodiment, the safety switch 400 is disposed at the hinge shaft 550, the wall of the hinge hole 526 is provided with a protrusion 528 for triggering the safety switch 400, and when the cover 520 is rotated downward to the closed state, the protrusion 528 triggers the safety switch 400. Specifically, a cavity for receiving the safety switch 400 is disposed at the hinge shaft 550, the safety switch 400 is received in the cavity, and the button 410 of the safety switch 400 is exposed out of the hinge shaft 550. The hinge hole 526 is a special-shaped hole, two sections with different inner diameters are arranged on the hole wall of the hinge hole 526, wherein the section with the smaller inner diameter is in clearance fit with the hinge shaft 550, and the protrusion 528 is arranged on the hole wall of the section with the larger inner diameter of the hinge hole 526.

Referring to fig. 12, when the cover 520 is in the open position, the protrusion 528 is offset from the button 410 and the safety switch 400 is in the unactuated position. Referring to fig. 13, when the cover 520 is rotated downward to the closed state, the protrusion 528 interferes with the button 410 to press the button 410, and the safety switch 400 is activated.

In order to make the safety switch 400 play a safety role, the inner wall of the cover body 510 is provided with a contact pin electrically connected with the safety switch 400, the top of the host 100 is provided with a needle seat electrically connected with the control board, when the sound-proof shield 500 is placed on the host 100, the contact pin is inserted into the needle seat, the safety switch 400 is electrically connected with the control board through the matching of the contact pin and the needle seat, and the control board judges that the sound-proof shield 500 is closed in place according to the trigger signal of the safety switch 400, so that the machine body can be started normally.

The other structures of the sixth embodiment are the same as those of the first embodiment, and are not described in detail here.

It will be appreciated that the specific configuration of the hinge bore 256 is not limited to that described above and shown in the drawings, and that other suitable configurations may be used.

It can be understood that, when the soundproof cover 500 is detached from the main unit 100, in order to enable the machine body to work normally, the user can select whether to use the soundproof cover by setting a button for installing the soundproof cover 500, and the control board determines whether to start the machine body on the premise of triggering the safety switch 400 according to the selection condition of the user.

In addition to the above preferred embodiments, the present invention has other embodiments, and those skilled in the art can make various changes and modifications according to the present invention without departing from the spirit of the present invention, which should fall within the scope defined by the appended claims.
