Abstract
The invention discloses a kind of aeration structures, it is characterized in that, including L-type ventilation shaft (1), the exhaust fan (2) internal in L-type ventilation shaft (1) is set, and is mounted on the rain insensitive device on the outlet air end of L-type ventilation shaft (1) by support rod (3)；The rain insensitive device includes the top cover (5) in inverted " V " font, is provided with top cover (5) lower end gutter (4).Top cover of the invention is inverted " V " font, and upper end is provided with gutter, can be very good to drain rainwater when rainy；Simultaneously, caping, which covers, is provided with gas vent, and top cover is internally located at the flashing board that " V " type is provided with below gas vent, which indoor air can be discharged, and flashing board can then prevent rainwater from entering the room, and keep the waterproof performance of aeration structure of the invention more preferable.
Description
Technical field
The present invention relates to field of ventilation equipment, in particular to a kind of aeration structures.
Background technique
Setting ventilation device is usually required in the buildings such as some workshops, workshop at present, and air draft is carried out to room air.So
And traditional its waterproof performance of air device is bad, is unable to satisfy demand.
Summary of the invention
The defect that it is an object of the invention to overcome traditional its waterproof performance of air device bad provides a kind of logical
Wind structure.
The purpose of the invention is achieved by the following technical solution：A kind of aeration structure, including L-type ventilation shaft are arranged in L
Exhaust fan inside type ventilation shaft, and the rain insensitive device being mounted on by support rod on the outlet air end of L-type ventilation shaft；Institute
Stating rain insensitive device includes the top cover in inverted " V " font, is provided with top cover lower end gutter.
It is provided with gas vent on the top cover, inside the top cover and is located at below gas vent drainage arrangement is installed；Institute
The both ends of drainage arrangement are stated through top cover.
The drainage arrangement is V-shaped flashing board, and the both sides of the flashing board are provided with along extending portion.
The present invention compared with the prior art, has the following advantages that and beneficial effect：Top cover of the invention is inverted " V " font,
And upper end is provided with gutter, can be very good to drain rainwater when rainy；Meanwhile caping covers and is provided with gas vent, and
Top cover is internally located at the flashing board that " V " type is provided with below gas vent, which indoor air can be discharged, and rain-proof
Plate can then prevent rainwater from entering the room, and keep the waterproof performance of aeration structure of the invention more preferable.
Detailed description of the invention
Fig. 1 is structure chart of the invention.
Specific embodiment
The present invention is described in further detail below with reference to embodiment, but embodiments of the present invention are not limited to
This.
Embodiment
As shown in Figure 1, aeration structure of the invention, including L-type ventilation shaft 1, it is arranged in inside L-type ventilation shaft 1
Exhaust fan 2, and the rain insensitive device being mounted on by support rod 3 on the outlet air end of L-type ventilation shaft 1.
Specifically, the air intake of the L-type ventilation shaft 1 is located at interior, outlet air end is then located outside, air outlet court
On.Exhaust fan 2 is mounted in the L-type ventilation shaft 1 by bolt, and is located at its air intake side, and support rod 3 then passes through welding
Mode is connect with L-type ventilation shaft 1.
Due to the L-type ventilation shaft 1 air outlet upward, as shown in Figure 1, the rain insensitive device includes in inverted " V " font
Top cover 5 is provided with 5 lower end gutter 4 of top cover.That is one end of the support rod 3 is welded on the outside of L-type ventilation shaft 1, another
End is then welded on top cover 5, and forms air-out passage between top cover 5 and L-type ventilation shaft 1.
As a preference, being provided with gas vent 6 on the top cover 5, installed inside the top cover 5 and below gas vent 6
There is drainage arrangement, top cover 5 is run through at the both ends of the drainage arrangement.Specifically, the drainage arrangement is the flashing board of V-shaped setting
7.When rainwater enters in top cover 5 from gas vent 6, rainwater can be dropped on flashing board 7, since the both ends of lid flashing board 7 are passed through
Top cover 5 is worn, therefore drop into the rainwater on flashing board 7 top cover 5 can be discharged along rain-proof 7, rainwater is avoided to enter interior.
In addition, the both sides of the flashing board 7 are provided with along extending portion 8, so as to preferably catch the rain entered in top cover
Water.
When work, indoor air is pumped into L-type ventilation shaft 1 by exhaust fan 2, and air is from the outlet of L-type ventilation shaft 1
The lower section that flashing board 7 is reached after discharge, due to the barrier effect of flashing board 7, air a part is from top cover and L-type ventilation shaft 1
Between air-out passage discharge, it is a part of then pass through the top that channel between top cover and flashing board 7 is discharged to flashing board 7, and from
Gas vent 6 is discharged.
As described above, the present invention can be realized well.
