Description

Inflatable connector for wirelessly transmitting air pressure data to an electronic device and its combination with a high pressure gas cylinder

Most of the bicycle inflators commonly used in the market in the early days were inflated by applying pressure and pressure. As the times progressed, the pump has moved toward the downsizing direction, but due to the shrinking volume of the pump, the force is applied.

The primary function of the inflatable joint is to quickly inflate with the CO2 cylinder, and it has a smaller size than the pump to facilitate carrying. Therefore, if the inflation joint is provided with a traditional mechanical pressure gauge for viewing the air pressure value during inflation, the pressure gauge The outer diameter must be greater than the outer diameter of the inflatable joint, which creates a sudden sensation of the appearance of the inflatable joint and also increases the volume of the inflatable joint. Moreover, even if the pressure gauge is forcibly set, in order to avoid the sudden appearance of the overall design, the attached pressure gauge volume must be reduced as much as possible, resulting in the digital scale and unit marking of the pressure gauge must be quite small, making it very difficult for the user to interpret the air pressure. Value. On the other hand, when performing the pumping operation, the inflation joint is connected with the tire nozzle, which will interfere or block the pressure gauge by the spokes.
