During rainy days, as shown in fig. 6, the rainwater falls in water catch bowl 100, under the effect of gravity in the rainwater, water catch bowl 100 overcomes the effort of elastic component and moves downwards, thereby drive rack 227 and gear 226 meshing, and then make gear 226 rotate so that baffle 223 revolute the axis of rotation and shelter from the rectangle logical groove, cabinet body 200 is sealed, prevent rainwater or moist air to enter into cabinet body 200, water catch bowl 100 is last to have seted up water drainage tank 110, the export of water drainage tank 110 is located the rectangle framed plate 222 top of the top, make water drainage tank 110 exhaust rainwater can fall on rectangle framed plate 222, when baffle 223 is sealed with cabinet body 200, rectangle framed plate 222 and baffle 223 synchronous rotation, make first sliding grid 224 and second sliding grid 225 slide in first slide rail 220 and second slide rail 221, and then make first sliding grid 224 and second sliding grid 225 move in the direction of keeping away from rectangle framed plate 222 axis of rotation, make first sliding grid 224 and first fixed grid shelter from rectangle framed plate 222 in order to shelter from rectangle framed plate 222, make water drainage tank 110 exhaust rainwater can fall on rectangle framed plate 222, when baffle 223 seals cabinet body 200, make first sliding grid 224 and second sliding grid plate 225 slide in first sliding grid plate 222 and second sliding grid plate 225 slide in first slide in second slide rail 220, and second sliding grid plate 221, and then the second sliding grid plate 222 slide in second sliding grid plate 222, and filter screen 228 is opened on the rectangle framed plate is opened in proper order, and filter screen 222 is opened in turn, and filter screen frame plate is opened simultaneously, and filter screen is opened on the second sliding grid plate is opened in order, and filter screen frame plate is opened.
When rain stops, water in the water collecting tank 100 is completely discharged through the water drainage tank 110, the water collecting tank 100 is slowly reset under the action of the elastic piece, so that the water collecting tank 100 drives the rack 227 to move upwards to drive the gear 226 to rotate, the baffle 223 rotates around the rotating shaft to open the rectangular through groove, the rectangular frame plate 222 shields the rectangular through groove, meanwhile, the rectangular frame plate 222 and the baffle 223 synchronously rotate around the rotating shaft to enable the first sliding grid plate 224 to slide in the first sliding rail 220 to enable the first sliding grid plate 224 to be restored to the initial position, and the folding filter screen 228 is retracted, so that holes on the filter screen are not blocked; the second sliding grating plates 225 slide in the second sliding rails 221 so that the second sliding grating plates 225 are restored to the initial position, the holes on the filter screen are not blocked, the rectangular frame plates 222 shield the rectangular through grooves as the water collecting grooves 100 are gradually restored to the initial position, and the filter screen on the rectangular frame plates 222 filters dust in the air to prevent the dust from entering the cabinet body 200.
The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
