Description

ventilation pipe device

This creation is about a kind of device, which refers to a kind of ventilation pipe body device that is fixed to each other and bent and dislocated for hidden protection, and can block strong wind and heavy rain outside, promote internal hot air convection to the outside, and make a large area continuous connection.

For a long time, no matter whether it is an iron house or a cement house, it is always very stuffy in summer, because it does not have enough convection equipment, nor does it have enough lighting system. Although some people have invented ventilation equipment, such as the patent number M551635 of the Republic of China Simple daylighting cover" new patent, its main structure is to set a perforation on the top of the building, the perforation is provided with a daylighting cover, the daylighting cover includes a frame edge and a transparent plate embedded in it, which cannot be connected continuously and cannot be used as The use of the roof is limited by the opening of the frame edge, and ventilation and convection cannot be generated; for example, the Chinese Patent No. M538058 "roof ventilator", which mainly consists of a ventilator body, including a top wall, which is arranged downward along the periphery of the top arm. The frame surrounding wall, the bottom edges of the two opposite side arms of the frame surrounding wall are respectively extended with a connecting part to form a trapezoidal shape, so as to provide a connection to the roof surface, the top wall and the trapezoidal bottom formed by the frame surrounding wall jointly define an air inlet, The top wall has an air outlet, and the air guide partition is sunken inside the ventilator body in an L shape. Its structure cannot be spliced, nor can it be combined with transparent plates to form a lighting structure. The air outlet and the air inlet are arranged in a straight line, so they cannot be protected by concealment, are easily damaged, and cannot be waterproof, windproof, and reversed; such as the Republic of China Patent No. I656307 "Building Ventilation Device", its structure includes a rectangular shape The frame unit defines an air chamber communicated with the interior and includes at least one guide frame bar, the air chamber has a ventilation opening and an air outlet opening oppositely arranged; the at least one ventilation unit is arranged on the at least one guide The frame bar has a ventilation groove group and forms a first flow channel; the ventilation unit includes a ventilation window. This kind of common product is a pipe body cast from aluminum alloy, which is not resistant to weather and has a single size that cannot meet the sizes of various inlet holes. The two baffles set inside are directly placed in the space of the frame unit, so that the law is hidden and protected, and it is also easily damaged and unable to prevent water, wind and backflow. The lighting structure above it must be combined with the frame unit to be used. In addition, the frame unit cannot be spliced continuously, which increases the inconvenience of use and greatly reduces its practicality. This is what the industry and consumers desperately want to break through.

In order to solve the above-mentioned deficiencies in the prior art, the main purpose of this creation is to provide a ventilation pipe body device. Using the effect of the prior art, this creation uses the ventilation pipe body to include the left plate group, the baffle blades, and the right plate group. And the mesh, wherein the left plate group has a straight plate connected to bend, a bottom plate with a lower ventilation hole, an inclined top plate and a horizontal top plate; the baffle blades are set on the straight plate; the right plate set is set on the left The other side of the plate group has connected and bent straight plates, bent middle plates, and straight plates with upper ventilation holes; the mesh is arranged on the bottom plate of the left plate group to overcome the difficulties in the prior art.

The secondary purpose of this creation is to provide a ventilation pipe body device, using the left plate group and right plate group that are fixed to each other and are bent and dislocated, and the straight plate in the left plate group is provided with baffle blades to provide hidden protection , and can block the external strong wind and heavy rain, promote the internal hot air convection and make a large area continuous connection.

Another purpose of this creation is to provide a ventilation pipe body device, which is provided with an opening for lighting and ventilation on the side wall, and a manhole that is opened by connecting the hinge with reinforced glass, and using the lower end to provide double convection.

", its structure also cannot be spliced, nor can it be combined with transparent boards to form a lighting structure. Since the L-shaped ventilator is directly arranged on the linear air outlet and the air inlet, it cannot be hidden and protected, and it is easy to damage and It cannot be waterproof, windproof and backflow; for example, the Republic of China special number I656307 "Building Ventilation Device", its structure is an aluminum alloy casting tube body, which is not resistant to weather, and the single size cannot meet various inlet sizes. The second baffle is directly placed in the space of the frame unit, so that the law is hidden and protected, and it is also easy to damage and cannot be waterproof, windproof and reversed. The lighting structure above it must be combined with the frame unit before it can be used, and the frame The units cannot be spliced continuously, which increases the inconvenience of use and greatly reduces its practicality.
