Description

Technical Field

[0001] The utility model relates to the technical field of ventilation and air exchange, in particular to a pipeline air exchange device. Background Art

[0002] Generally, a device with a ventilation function requires a pipe connecting indoor and outdoor areas to be installed, so as to discharge indoor air to the outside or to draw outdoor air into the room. In order to prevent insects and other debris or foreign objects from entering the room through the pipe, a mesh structure, such as a protective net, is generally set at the opening of the pipe.

[0003] In the prior art, a Chinese patent with the announcement number CN208590285U discloses a ventilation hole protection net, including a ventilation hole, one side of the ventilation hole is connected to a ventilation pipe, and the ends of the ventilation hole are provided with a bird-proof net and an insect-proof net in sequence; a bird-proof net outer frame is provided on the periphery of the bird-proof net, an insect-proof net outer frame is provided on the periphery of the insect-proof net, a ventilation hole ventilation outer frame is provided between the bird-proof net outer frame and the insect-proof net outer frame, a window strip is provided between the ventilation hole ventilation outer frame and the ventilation hole, and a fixing pin is provided through the bird-proof net outer frame, the ventilation hole ventilation outer frame and the insect-proof net outer frame. The structure is simple, the installation is convenient, the installation is firm, and it can effectively prevent people from entering the ventilation hole and causing safety accidents, and can also effectively prevent pests, sparrows, mice and other harmful creatures from entering the ventilation hole, avoiding causing grain storage safety problems.

[0004] However, the above scheme still has some shortcomings. For example, although the above scheme is provided with a bird-proof net and an insect-proof net in sequence from the vent to the inside, which can effectively prevent pests, sparrows, mice and other harmful creatures from entering the pipe vent, it not only cannot kill the pests, but also cannot clean the dust adhering to the net. Too much dust accumulation can easily cause the pipe vent to be blocked, thereby affecting the effect of pipe ventilation, and thus reducing the practicality of the device. Utility Model Content
