However, the humidity sensing equipment used in common ventilation equipment is generally close to the air outlet of the humidification equipment, which can easily affect the detection effect of the humidity sensor. Therefore, a building automatic ventilation device is needed to solve the above problems. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a building automatic ventilation device, comprising a mounting connecting plate, an axial flow fan is installed at the center of one side of the mounting connecting plate, a spray assembly is fixedly connected to the lower surface of the mounting connecting plate, the spray end of the spray assembly is directly opposite to the air outlet end of the axial flow fan, a detection assembly is fixedly connected to the top of one side of the mounting connecting plate, mounting partitions are fixedly provided on both sides of the mounting connecting plate, and an expansion bolt is threadedly connected to one end of each of the mounting partitions.

[0006] Preferably, the spray assembly includes a water storage tank, and a connecting guide plate is fixedly connected to the lower surface of the mounting connecting plate, and a liquid inlet conduit is inserted into the interior of the connecting guide plate.

[0007] Preferably, a plurality of spray heads are fixedly mounted on the upper surface of the liquid inlet conduit, and each of the spray heads passes through the connecting guide plate and is directly opposite to the air outlet end of the axial flow fan.

[0008] Preferably, the liquid outlet end of the water storage tank is connected to a liquid inlet hose via a solenoid valve flange, and one end of the liquid inlet hose is connected to a liquid inlet conduit flange.

[0009] Preferably, the detection component includes a connecting partition, the bottom of one side of the connecting partition is provided with an adjustment slot, the interior of the adjustment slot is plugged with an adjustment transverse plate, and the upper surface of the adjustment transverse plate is provided with a plurality of positioning holes.

[0010] Preferably, a positioning pin is inserted into the upper surface of the connecting partition near the adjusting horizontal plate, and the positioning pin is connected with the positioning through-hole at the opposite position. A humidity sensor is fixedly installed at one end of the upper surface of the adjusting horizontal plate. The purpose of this arrangement is: the humidity inside the building can be detected by the humidity sensor. When the indoor temperature is relatively dry, the solenoid valve can be opened to supply water to the spray head, and the air introduced by the axial flow fan is humidified by spraying mist through the spray head. The adjusting horizontal plate can be positioned by the positioning pins and positioning through-holes. The distance between the humidity sensor and the spray head can be adjusted by the adjusting through-slot to avoid the humidity sensor and the spray head being too close. The detection component and the air outlet end of the axial flow fan are in two different positions, thereby reducing the detection error of the humidity sensor.

[0011] Technical effects and advantages of the utility model:
