The lower shell 100 is provided with a accommodating cavity 110 with an opening facing upward. The electrode assembly 300 is arranged in the accommodating cavity 110. The upper cover 200 is locked on the top of the lower shell 100 by a locking screw 500 to cover the top of the accommodating cavity 110. A socket 210 is provided on the upper cover 200, and the socket 210 vertically penetrates the upper cover 200 to connect the accommodating cavity 110 with the outside world. The electrode assembly 300 has an electrode port 310, and the electrode port 310 is plugged into the socket 210. A sliding cover assembly 400 is provided on the top of the upper cover 200. The sliding cover assembly 400 includes a mounting frame 410 and a sliding cover 420. The mounting frame 410 is arranged around the top 210 of the socket, and the sliding cover 420 is slidably connected to the mounting frame 410 and can slide on the mounting frame 410. The bottom surface of the sliding cover 420 is attached to the top surface of the upper cover 200, and the sliding cover 420 slides to open the socket 210 for plugging or cover the top of the socket 210.

[0046] The utility model provides a socket 210 on the upper cover 200 for the electrode port 310 to pass through, and provides a sliding cover assembly 400 on the top of the socket 210, and the sliding cover assembly 400 is configured as a mounting frame 410 surrounding the socket 210 and a sliding cover 420 slidably connected to the mounting frame 410, so that the sliding cover 420 can slide back and forth on the mounting frame 410. When the electrode port 310 needs to be used, the sliding cover 420 is slid to a position avoiding the socket 210 for plugging; when the electrode port 310 is not needed, the sliding cover 420 can be slid to the top of the socket 210. At this time, the sliding cover 420 is fitted with the outer peripheral side of the top of the socket 210 to completely cover the socket 210, so as to prevent dust and liquid in the external environment from entering the socket 210, thereby achieving effective dust prevention for the electrode port 310 and preventing the electrode port 310 from being damaged by moisture, thereby extending the service life of the electrode port 310.
