Brush, can effectively be removed, the structure design is to make full use of the advantage of natural conditions, prevents Air Filter to the dust in Air Filter
The phenomenon of blocking occurs, and ensure that the ventilation condition in metal shell.
3. heat dissipation channel is set obliquely, can not only arrange in pairs or groups conventional design thinking of the drainpipe close to ground, Er Qieji
In the architectural feature of the present apparatus itself, the structure design can during effectively pre- preventing rain wash caused spatter liquid pour in down a chimney it is scattered
The problem of in hot hole, occurs, and improves the security during use.
4. due to forming vortex counterclockwise in the current dropping process in the Northern Hemisphere, the present invention is set in the inwall of drainpipe
Anticlockwise helical groove, the whereabouts for current of arranging in pairs or groups, resistance of the draining inside pipe wall to current is effectively reduced, improved under rainwater
The dynamics and speed fallen, improve the scouring effect of Air Filter.
5. Ji Yutai upper end sets shutter, multiple leaking holes are set on shutter, leaking hole is up big and down small cone
Bench-type structure, this structure design can block to leaf, the branch of large volume, while rainwater is by the downward draining of leaking hole,
And the leaking hole of frustum type is advantageous to the quick collection of rainwater, residual of the rainwater on shutter is reduced, slows down shutter life
The problem of rust.
6. setting cover plate and water logging induction module on Ji Yutai, under original state, hydraulically extensible cylinder is contraction state, lid
Plate covers to shutter or Ji Yutai, plays the aging influence brought on shutter or Ji Yutai that prevents from exposing to the weather,
So as to improve its service life；When water logging induction module detects rain in environment, central processing mould is transmitted a signal to
Block, central processing module control hydraulically extensible cylinder elongation, cover plate is jacked up, exposes shutter or Ji Yutai, for automatic
Collect rain, it is convenient and swift；Because signal has the problem of decay in transmit process, by water logging induction module and central processing
Setting signal conditioning module between module, effectively improve stability and integrality in signal transmit process.
