Title:
AUTOMATIC AIR INFLATION DEVICE FOR LIFEJACKET
Document Type and Number:
WIPO Patent Application WO/2013/091207
Kind Code:
A1
Abstract:
An automatic air inflation device for a lifejacket comprises a main body housing (10) and a piercing needle rod (9) for piercing a gas source, the piercing needle rod being placed inside the main body housing in a manner of being capable of being pushed, and further comprises a control circuit board, and a motor (4), a battery (8), and a water sensor contact (1) which are connected to the control circuit board. The motor is connected to the piercing needle rod through a transmission mechanism of a threaded screw rod (7). The energy of the device is provided by the battery, and when the water sensor contact is in contact with water to trigger the control circuit board to start the motor, the motor rotates to convert, through the transmission of the threaded screw rod, a torque force into a pushing force to push the piercing needle rod to pierce the gas source. The device, different from an existing working manner of pressing a spring in advance with a paper bag and compressed powder, converts electric energy into mechanical energy to work, and the device can be used repeatedly, is not subject to the influences of external air temperature and humidity, and is not limited by a service life, thereby providing more convenient and intelligent operation functions.
