barometer device

Abstract

A barometer device includes a barometer, a barometer sensor, and a pointer. The barometer has an air inlet on its outer side and an internal accommodating space. The barometer sensor is disposed in the barometer accommodating space and includes a lever connecting to first and second elastic forces at its two ends. The first elastic force is connected to the air inlet of the barometer to detect the external air intake status and provides a synchronously responsive force transmission. The pointer is synchronously linked to the lever of the barometer sensor. This allows the barometer sensor to be connected to an external air pressure source. In inflation mode, air pressure enters the barometer sensor, and the first elastic force extends upwards under elastic tension. An upward-moving power transmission is formed, which pushes the brake to move upward and compress the second elastic force. At the same time, it causes the pointer to move upward and rotate in the first direction. When in the deflating mode, the air pressure inside the air pressure sensing device drops, causing the second elastic force to release and extend. In the opposite direction, it pushes the brake to move downward and compress the first elastic force downward, forming a downward-moving power transmission. This causes the pointer to move downward and rotate in the second direction. This allows the pointer and the brake of the air pressure sensing device to be connected to form a suspended pneumatic pointer, which can automatically control the direction of pointer rotation according to changes in air pressure, thus achieving a simple air pressure detection device.
