a grid is fixedly arranged at one end of the exhaust air port in the connecting pipe, and the purpose of the grid is to avoid the influence of the crawling of the reptiles on the use safety;

a wind shield is hinged at one end of the connecting wind gap in the connecting pipe through a hinge; the hinge is arranged at one side of the connecting pipe in the air outlet direction; a limiting piece is arranged at the rear part of the wind shielding piece, namely at one side of the air inlet direction of the connecting pipe, corresponding to the wind shielding plate;

one end of the air exhaust port is provided with a rain cap.

That is, through the setting of spacing piece, can prevent that the windshield from opening backward, namely to the air inlet direction of connecting pipe to when this prevents that the wind from flowing backward, still can not influence the air-out.

Furthermore, the connecting pipe is in a circular pipe form, the outer diameter of the wind shield is slightly smaller than the inner diameter of the connecting pipe, and the connecting pipe is in a circular pvc plate form.

Further, the rain hat is arranged in the following mode: the connecting pipe outer wall has cup jointed rain-proof cap in wind gap one end of airing exhaust, the rain-proof cap includes the assembly lantern ring, fixedly provided with connecting rod on the assembly lantern ring, connecting rod end fixed connection weather shield.

The beneficial effects of the utility model are as follows: the utility model has simple structure and convenient use, solves the problem of serious ash inlet caused by the backward flow of wind current in the wind cap in the prior art through a simple structure, isolates most of dust through the arrangement of the one-way baffle plate, and reduces the maintenance frequency of equipment. The arrangement mode of the bend pipe connected at the same time can flexibly assemble the equipment at the air outlets with various orientations and flexibly adjust the orientations of the air exhaust air outlets.

Detailed Description

Referring to fig. 1, 2, 3, 4 and 5, the unidirectional choke cap for central air conditioner exhaust comprises a connecting pipe 2, wherein the connecting pipe 2 is in a bent pipe form, and air inlets at two ends of the connecting pipe are mutually vertical; wherein one end of the air port is an exhaust air port, and the other end of the air port is a connecting air port; that is, when the air exhaust port is upward, the air port is connected to the side;

a grid 3 is fixedly arranged at one end of the exhaust air port in the connecting pipe 2, and the grid 3 is arranged to avoid the influence of crawling animals on the use safety;

a wind shield 5 is hinged at one end of the connecting wind gap in the connecting pipe 2 through a hinge 4; the hinge 4 is arranged at one side of the connecting pipe 2 in the air outlet direction; a limit piece 6 is arranged at the rear part of the wind shielding piece 5, namely at one side of the air inlet direction of the connecting pipe 2, corresponding to the wind shielding plate;

one end of the air exhaust port is provided with a rain cap 1.

That is, by the arrangement of the limiting piece 6, the wind shielding piece 5 can be prevented from being opened backwards, namely, towards the air inlet direction of the connecting pipe 2, so that the air flow is prevented from flowing backwards, and the air outlet is not influenced.

Further, the connecting pipe 2 is in a circular pipe form, the outer diameter of the wind shielding piece 5 is slightly smaller than the inner diameter of the connecting pipe 2, and the connecting pipe is in a circular pvc plate form.

Further, the waterproof cap 1 is provided in the following form: the rain-proof cap 1 has been cup jointed in connecting pipe 2 outer wall, wind gap one end of airing exhaust, rain-proof cap 1 includes assembly lantern ring 9, fixedly on assembly lantern ring 9 is provided with connecting rod 8, 8 end fixed connection weather shield 7 of connecting rod.

Preferably, the mesh 3 is in the form of a fine mesh.

Preferably, the commercial product of the connecting tube 2 has various sizes, and the materials include metal and pvc.

The utility model is used when: the connecting pipe 2 can be sleeved at one end of the connecting port or connected to any exhaust port in a sleeved mode, and one or more of riveting, sealing glue or interference fit sleeving means are adopted to realize stable connection; when the air-conditioner exhaust air is exhausted from the connecting air port to the exhaust air port, the wind flow blows the wind shielding piece 5 for continuous exhaust; when the air exhaust stops, if the air flows back when meeting the wind flow, the wind shielding plate 5 can block most of the wind flow from entering the air exhaust pipeline at the rear part of the air shielding plate, so that only dust is accumulated in the connecting pipe 2, and only the rain cap 1 is required to be removed for simple maintenance when the air exhaust is maintained. Greatly reduces the original maintenance frequency. Meanwhile, the equipment can be flexibly assembled at the air ports with various orientations through the bent pipe arrangement mode of the connecting pipe 2, and the orientation of the air exhaust air port can be flexibly adjusted.
