In other embodiments, the locking groove may be disposed on the periphery of the opening 11, and the sealing member 4 may be provided with a convex structure.
The switch 2 in this embodiment is a mechanical microswitch, the trigger portion 21 is an elastic trigger arm, and includes a pressing arm 211 disposed below the opening 11 and a trigger arm 212 connected to the switch 2, the pressing arm 211 is disposed in the guide groove 42, and further, in order to prevent the front end of the pressing arm 211 from being too sharp and piercing the elastic deformation portion 41 during repeated pressing, which results in failure of the overall structure, a curled edge structure is processed at the abutting portion of the pressing arm 211 and the elastic deformation portion 41 in this embodiment.
Still including the spacing muscle 13 of shaping on the inside wall of holding chamber 1 in this embodiment, spacing muscle 13 in this embodiment is straight arm buckle structure, and arranges the below of sealing member 4 in, and is close to the lower extreme setting of sealing member 4, prevents to take place under the influence of factors such as external force, and the phenomenon that the excessive direct opening part of following drops is pushed down to the sealing member. Of course, in other embodiments, the above-mentioned limiting rib 13 may also be a common convex structure.
In the cover opening power-off structure in this embodiment, when the cover 5 is opened, the trigger arm 212 is reset by the elastic reset force, the switch 2 is opened, the device is powered off, and the pressing arm 211 presses the elastic deformation portion 41 to protrude toward the cover 5. When the cover 5 is closed, the position of the elastic deformation part 41 is pressed down, the trigger arm 212 is driven to rotate downwards, the switch 2 is closed, and the device is powered on.
