Referring to fig. 1-10, the present embodiment provides an electronic scale 100, which includes a scale body 110, a touch button 120, a trigger element 130, a cover 140 and a processor 150. The touch key 120 is provided on the scale body 110. The triggering member 130 is mounted to the scale body 110. The touch key 120 and the triggering element 130 are both connected to the processor 150.

Further, in some embodiments of the present application, in the first connection state, the trigger element 130 disconnects the processor 150 from the IO port corresponding to the ground, and in the second connection state, the trigger element 130 connects the processor 150 from the IO port corresponding to the ground.

In some embodiments of the present application, in the first connection state, the trigger element 130 connects the corresponding IO port of the processor 150 to ground, and in the second connection state, the trigger element 130 disconnects the corresponding IO port of the processor 150 to ground.

By disconnecting or connecting the processor 150 to the ground corresponding to the IO port, the port of the processor 150 connected to the trigger element 130 changes between a high potential and a low potential, so that the processor 150 can reset the touch key 120 according to the change of the potential, thereby avoiding the failure of the touch key 120 caused by the cover closing or the cover removing.
