FIG. 1 is a perspective view of the present invention;

fig. 2 is a front view of the present invention.

In the figure: the device comprises a main body 1, a sleeve 2, a rain-proof drip penetration assembly 3, a baffle 4, a wind vane 5, an arrow 6, a rotating shaft 7, a wind rudder plate 8, a top cap 9, an exhaust hole 10, a base 11 and a shutter 12.

Detailed Description

An embodiment of the utility model provides a roofing air discharge cap that effectively prevents rainwater inflow, as shown in fig. 1-2, set up on the export of roof blast pipe. Comprising a body 1 and a rain-drip prevention member 3. The main body 1 is made of pottery clay. A rain-proof drip penetration assembly 3 is provided on the main body 1. The body 1 comprises a plurality of sleeves 2, a base 11 and a top cap 9. A plurality of sleeves 2 are arranged end to end between the base 11 and the top cap 9. The sleeve 2 positioned at a high position is provided with a plurality of exhaust holes 10. The rain-proof drip penetration assembly 3 is arranged on the top cap 9. The raindrop penetration prevention module 3 includes a baffle 4 and a wind vane 5. The wind vane 5 is arranged on the top cap 9, and the baffle 4 is connected with the wind vane 5. The inner side of the baffle 4 corresponds to the exhaust hole 10. The baffle 4 is arranged at the same side of the tip of the wind vane 5. The baffle 4 is provided with a slot. A plurality of louvers 12 for blocking rainwater from the outside are provided in the grooves.

The utility model discloses a guarantee that it is pleasing to the eye, and then with the design of whole exhaust cap for the mao bamboo form, fire through argil simultaneously and form, nevertheless shape and material make its exhaust hole 10 can only set up on the side of main part 1 like this, when meetting rainy weather, this kind does not have rain-proof eaves and the vertically exhaust hole lets the rainwater get into wherein easily when its hole direction. Thereby affecting the exhaust effect.

Therefore, the utility model discloses on original basis, with the cooperation of direction indicator 5 and baffle 4 for behind the rain especially wind, 6 very first time of point arrow of direction indicator 5 only need the arrival of wind to, and then drive baffle 4 and remove the direction that the raindrop blown and shelter from. Effectively preventing rain water from entering the body 1.

Through the arranged shutter 12, rainwater on the outer side of the shutter 12 can be effectively prevented from entering, and the corresponding exhaust hole 10 on the inner side can perform normal exhaust operation. The exhaust efficiency is ensured.

The wind vane 5 comprises a rotation shaft 7, an arrow 6 and a rudder plate 8. The rotating shaft 7 is pivoted on the top of the top cap 9, and the arrow 6 and the wind rudder plate 8 are symmetrically arranged on the rotating shaft 7. The shutter 4 is connected to a rotary shaft 7.

During the use, at first when the weather that appears raining and accompany the wind-blowing, this moment because the utility model discloses a shape, its raindrop must enter into main part 1 from exhaust hole 10 under the influence of wind in, wind vane 5 is under the influence of wind this moment, and its arrow point 6 can be just facing the arrival of wind. Meanwhile, the baffle 4 is driven to rotate, so that the baffle 4 can block the exhaust holes 10 which are right opposite to the air inlet, and the outer side rainwater can be blocked by the louvers 12 on the baffle 4, but the gas and smoke dust which are diffused from the corresponding exhaust holes 10 on the inner side can be discharged from gaps among the louvers 12.

In summary, the roof exhaust cap for effectively preventing rainwater from flowing in is formed by matching the main body 1, the baffle 4, the wind vane 5 and the louver 12. Make the utility model discloses can open to it and protect the through-hole on the main part 1 side, especially under windscreen wiper wind weather down, effectively make things convenient for the rainwater to get into main part 1 along with wind in, the tripe 12 that sets up moreover can also block the water droplet from the 4 outsides of baffle, can not influence the exhaust of its inboard exhaust hole 10.
