The in-process of inflating, the atmospheric pressure in the product of aerifing increases gradually, when the product of aerifing accomplishes soon and aerifys, the promotion stopper receives the effect of atmospheric pressure to outwards remove, close the air vent through pull rod pulling closure cover piece removal gradually, and pressure is big more, the amplitude that the promotion stopper removed is big more, the amplitude that the closure cover piece removed is also big more, the area that the air vent was closed by the lid is big more, the opening of ventilating of air vent is little less, it is slow more to admit air, fine guard action has been played to the product of aerifing, prevent to aerify and lead to aerifing the product and break gas leakage. The pressure in the inflatable product is gradually increased, the ventilation openings of the ventilation holes are gradually reduced, the inflation speed and the inflation quantity are gradually reduced, and the inflatable product is well protected. When the inflatable product finishes inflation, the sealing cover plate moves to the limit position, the vent holes are completely covered, and the inflatable product can not be inflated any more at the moment, so that the inflatable product is prevented from being broken and leaking air. In the actual use process, the adjusting knob is rotated according to different types of inflatable products to adjust the pretightening force of the adjusting spring, and the pretightening force of the adjusting spring acting on the pushing plug is changed to adapt to different bearing pressures of the inflatable products.
The above-described embodiments are merely preferred embodiments of the present invention, which is not intended to be limiting in any way, and other variations and modifications are possible without departing from the scope of the invention as set forth in the appended claims.
