barometer device

Abstract

A barometer device includes a barometer, a barometer sensor, and a pointer. The barometer has an air inlet on one side and an internal accommodating space. The barometer sensor is located in the barometer accommodating space and includes a lever connecting two ends to first and second elastic units respectively. The first elastic unit is connected to the air inlet of the barometer to detect the external air intake state and provides a synchronously responsive elastic force. 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. When in inflation mode, air pressure enters the barometer sensor, and the first elastic unit extends upwards under elastic tension. This creates an upward force transmission, pushing the brake to move upward and compress the second elastic unit. Simultaneously, it causes the pointer to move upward and rotate in the first direction. In the deflation mode, the internal air pressure of the air pressure sensing device decreases, causing the second elastic unit to release and extend elastically. This, in turn, pushes the brake to move downward and compress the first elastic unit downward, creating a downward force 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 pointer's rotation direction according to changes in air pressure, thus achieving a simple air pressure detection device.

Claims

1. A barometer device, comprising: A barometer has a housing space connecting a first and a second chamber. A spiral groove is provided at the top of the second chamber corresponding to the pointer. A barometer sensor is disposed in the housing space and has a linearly displaceable actuator. A first and a second elastic unit are connected to the two ends of the actuator, moving synchronously and in the same direction. The first elastic unit is located in the first chamber and moves elastically within the first chamber space. The second elastic unit is located in the second chamber and moves elastically within the first chamber space. The first elastic unit is a hollow elastic body with an air hole at the bottom and a retractable and foldable bending section on the outer ring side, which can expand and contract according to the air pressure, thus forming the power source for the up-and-down movement of the first elastic body. The second elastic unit is an elastic element. The first elastic body and the second elastic unit... The pressure gauge consists of two elastic bodies positioned vertically and relative to each other along the same longitudinal direction. A pointer, located inside the gauge, is connected to a pressure sensing device and operates synchronously. An external pressure source is connected to the bottom of the pressure sensing device, creating an elastic connection with the first elastic unit. The first elastic body of this unit is raised and lowered by the pressure source. A retractable and foldable section on the outer ring side expands and contracts in response to varying pressure levels. This provides the power source for the first elastic body's vertical movement, driving the actuator to move synchronously. The second elastic body of the second elastic unit contracts and expands relative to the first elastic body's movement, causing the actuator to reciprocate linearly between the first and second elastic bodies, and simultaneously rotating the pointer. This results in a pressure gauge that automatically controls the pointer's rotation direction based on pressure changes and allows for easy detection of pressure levels.

2. The pressure gauge device according to claim 1, wherein the first elastic unit is a hollow rubber elastomer, and the outer ring side is provided with a retractable and foldable bending section, which is wavy.
