When the cover is locked, the cover cannot be opened, thereby preventing the explosion-proof motor from being accidentally opened during operation, thereby causing danger. If it rains during operation, rainwater will flow into the water receiving bin, and the water receiving bin will be moved downward by the gravity of the rainwater. The water receiving bin will drive the baffle plate 3 to move downward, and the baffle plate 3 will cover the vent. When the baffle plate 3 covers the vent, rainwater can be prevented from entering the interior of the machine body. BRIEF DESCRIPTION OF THE DRAWINGS

When the water receiving bin 410 moves downward, the water receiving bin 410 will drive the baffle plate 3 409 to move downward. When the baffle plate 3 409 moves downward, the baffle plate 3 409 will block the vent. When the baffle plate 3 409 blocks the vent, rainwater can be prevented from entering the inside of the machine body 1. When the rain stops, rainwater will flow out through the fine groove at the bottom of the water receiving bin 410. After the rainwater flows out, the baffle plate 3 409 will move upward under the elastic force of the spring 3 407. When the baffle plate 3 409 moves upward, the vent will leak.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
