New description: [New technical field] This creation department is about a kind of cover, especially an anti-wind structure for exhausting and exhausting hoods installed on buildings. [Prior Art] According to the current general building ventilation system, such as exhaust fans, range hoods, gas heaters, exhaust, exhaust, all need to bury the exhaust and exhaust pipes in the building's external walls, and in order to block the birds Invasion of insects and avoidance of rain outside the house: irrigation • Most of the exhaust and exhaust pipes are equipped with exhaust and exhaust hoods. For example, the new patent certificate number elbow 326622 "outdoor ventilation hood with high ventilation effect" is a conventional exhaust and exhaust hood comprising: a connecting tube, the inner end of the connecting tube is connected to the venting tube An outlet end; a venting cover for arranging the outer end of the connecting sleeve, the venting cover extending outwardly with a flange having an inner diameter greater than an inner diameter of the connecting tube and forming the end surface of the flange a mask surface which is laterally stamped with a plurality of flaps which are inclined from top to bottom, and the stretcher forms a plurality of laterally elongated vents, the conventional exhaust and exhaust hood Because the mask surface is formed by the end face of the outer K-flange, that is, the mask surface is disposed in a postage when a large wind and rain is encountered, and the strong wind is still easily laterally passed through the mask. Inverting into the long vents into the exhaust and exhaust pipes, and the rain is easy to arrive again. The wind blows back against the upper surface of the mask surface to infiltrate into the exhaust and exhaust smoke (4), so that it can not achieve the effect of blocking the wind and rain. . [New content] 3 This creator has several of the above-mentioned conventional exhaust and exhaust hoods, which are resistant to wind and rain, and are not good. When encountering heavy wind and rain, it is still easy to have rainwater pouring into the exhaust and 2 smoke. In the case of the thoughts and creations of the thoughts and the test sample test, and many revisions and improvements, the final creation of this creation. The present invention provides an anti-wind structure for exhausting and exhausting hoods, wherein the exhausting and exhausting hood includes a connecting pipe member and a cover cover, wherein the pipe of the connecting pipe member has a plurality of outward elastic tabs, and When the connecting pipe is sleeved with the exhausting and exhausting pipe, the elastic tab is pressed against the inner surface of the exhausting and exhausting pipe, and the shielding cover is a plate-shaped body, and the cover is fixed at one end of the connecting pipe. The front surface is provided with a sinking groove, and the groove surface of the sinking groove is formed by punching and forming a plurality of laterally elongated blades which are inclined upwards and downwards to form a plurality of vents on the groove surface of the sinking groove. Furthermore, a drain hole is further disposed on the lower side of the groove surface of the sunshade cover, and a plurality of lugs having an elongated hole can be disposed around the edge of the side cover, without the use of the lug directly by the joint cover member. The hole is provided for the locking element to be locked. The main purpose of the present invention is that it can not only block the wind and rain from the upper and lower outer blades by the shielding cover, but also the leaves >} and the ventilation system are arranged on the sinker surface, so that when the gland encounters a large wind and rain, It can prevent the strong wind alone or the cool rainwater from being blown into the exhaust and exhaust pipe from the side, so as to achieve the effect of the wind and rain.
