SYSTEM FOR DETECTING AND DETERMINING THE TYPE OF AN INFLATABLE DEVICE BEING COUPLED WITH AN AIR SUPPLY DEVICE

摘要

A system for detecting and determining the type of an inflatable device being coupled with an air supply device is disclosed. The inflatable device includes an inflatable unit connected to a connector via an air delivery line. The air supply device includes a pressurized air supply unit and a pressure detection unit connected to a coupler. The connector is coupled with the coupler via several air inlet pipes. One of the air inlet pipes is a blocked pipe, a relative position of which on the connector varies with the type of the inflatable unit. The pressure detection unit determines the inflatable unit type by detecting the relative position of the blocked air inlet pipe, and the pressurized air supply unit supplies air of suitable pressure to the inflatable unit according to the type thereof, enabling the inflatable unit to properly massage a user's muscles to improve the blood circulation thereof.

主权项

1. A system for detecting and determining the type of an inflatable device being coupled with an air supply device, comprising:
an inflatable device including at least one air delivery line having two opposite ends, an inflatable unit connected to one end of every air delivery line, and a connector connected to the other end of every air delivery line and being a connecting head having a plurality of air inlet pipes; and an air supply device internally including a pressurized air supply unit and a pressure detection unit, and externally including a coupler adapted to connect with the pressurized air supply unit and the pressure detection unit; the coupler including a plurality of coupling pipes corresponding to the air inlet pipes and constituting a coupling head corresponding to the connecting head formed by the connector; wherein the inflatable unit is differently configured according to a usage type thereof, and one of the air inlet pipes on the connector is a blocked pipe while all other air inlet pipes are open pipes; and wherein a position of the blocked air inlet pipe relative to all other open air inlet pipes on the connector varies with the type of the inflatable unit connected to the connector via the air delivery line, and the pressure detection unit detects the relative position of the blocked air inlet pipe on the connector to determine the exact type of the inflatable unit of the inflatable device being currently coupled with the air supply device.
