Abstract

The embodiment of the invention discloses an inflating device and a control method based on the same. The inflating device comprises an inflating needle, an air pressure sensing piece, a signal piece,a control piece, a switch piece and a battery; the inflating needle comprises an inflating needle tip and an inflating needle tube which are integrally formed and communicate; the air pressure sensing piece comprises a protecting outer shell, an air pressure sensing chip, a first wire lead, a circuit board, a second wire lead, an optical fiber, and a protecting inner shell; and the protecting inner shell is arranged in the protecting outer shell. The control method of the inflating device comprises the step that an air pressure threshold is given to the control piece, so that the switch pieceis controlled to be turned off when the air pressure detection value exceeds the air pressure threshold. According to the inflating device and the control method, the air pressure in an inflated object can be monitored in real time, all the inflating steps can be completed only by simply inputting the target air pressure or the name of the to-be-inflated object, and the convenient and intelligenteffects are achieved.

Description

technical field [0001] The invention relates to the technical field of inflating, in particular to an inflating device and a control method based on the device. Background technique [0002] The special air needle for the pump is a tool used to assist in pumping, mainly suitable for ball products. When in use, one end is fixed on the pump, and the other end is inserted into the object that needs to be pumped, such as a ball, and then the gas is transmitted through the pump for pumping. , is a practical and convenient pumping tool. But the traditional inflating needle is only used as a single inflating tool, and can only play the role of connecting the inflator and the sphere. As we all know, when playing basketball, football and other ball games, the air pressure in the ball needs to be controlled within an appropriate range. However, when using traditional air needles to inflate the ball, the air pressure in the ball cannot be controlled, and the air pressure in the ball i...
