Problems solved by technology

[0002] At present, the main way to know the wind direction is to go to the scene to observe the wind vane to determine the wind direction. Sometimes it is inconvenient to observe the wind direction in this way, especially in severe weather conditions. It is more difficult and difficult to observe the wind direction in this way. inconvenient

Embodiment Construction

[0010] The scheme of the present invention will be described in detail with reference to the accompanying drawings: a wind direction informer is composed of a wind direction indicating device and a wind direction display circuit, a wind vane 1 is contained in the wind direction indicating device, a chassis 6 for supporting the wind direction indicator, and a small Shaft 2, one end of wind vane 1 is arrow-shaped, and the other end is wing-shaped. There is a small magnet 3 under the arrow-shaped end and is connected with it. The middle position of wind vane 1 occupies a small hole and is installed on the small shaft. 2, the cooperation between the small hole and the small shaft 2 is a dynamic fit, that is, the wind vane 1 can rotate freely along the small shaft 2, that is, the arrow of the wind vane 1 will rotate and point to the direction of the wind under the blowing of the wind, and the chassis 6 is in the shape of a circle, the center of the chassis 6 is equipped with a small...

Abstract

The present invention relates to a wind direction informing device composed by a wind direction indicating device and a wind direction displaying circuit, wherein the wind direction indicating device includes a wind vane, a chassis and a small shaft. One end of the wind vane shows an arrow shape and the other end of the wind vane shows a wing shape, and the underpart of the arrow-shaped end contains a small magnet, wherein the small magnet is connected with the arrow-shaped end; and the underpart of the chassis contains eight Hall elements evenly arranged on the circumference of the chassis in eight directions, i.e., east, west, south, north, northeast, southeast, northwest and southwest. According to the operating principle of the Hall element, it is known that once the Hall element contacts with a magnetic field, the Hall element can output a voltage, so that when the small magnet on the wind vane contacts any one of the Hall elements in any direction, the Hall element in that direction outputs a voltage, wherein the voltage enables the corresponding light emitting diode to illuminate through the displaying circuit, and thereby the wind direction can be determined by merely observing the orientation of the luminous LED indoors.

Description

Technical field [0001] The invention relates to a notification device, in particular to a wind direction notification device. Background technique [0002] At present, the main way to know the wind direction is to go to the scene to observe the wind vane to determine the wind direction. Sometimes it is inconvenient to observe the wind direction in this way, especially in severe weather conditions, it is more difficult and difficult to observe the wind direction in this way. inconvenient. Contents of the invention [0003] The purpose of the present invention is to provide a wind direction informer, which can know the wind direction indoors according to the display. A wind direction display circuit constitutes a wind direction informer. The wind direction indication device contains a wind vane, a chassis for supporting the wind vane, and a small shaft. One end of the wind vane is arrow-shaped, and the other end is a machine. Wing-shaped, the arrow-shaped end below contain...
