Abstract

The application relates to the technical field of air pressure control, and discloses an air pressure adjusting method and air pressure adjusting equipment for inflatable objects. The method includes determining a target air pressure value that is lower than a current air pressure value of the inflatable object, exhausting air within the inflatable object to reduce the air pressure value of the inflatable object, and supplementing air to the inflatable object when the air pressure value of the inflatable object is lower than the target air pressure value. The method adopts a mode of greatly reducing the air pressure value of the inflatable object, so that the inflatable object spans the target air pressure value and falls into a range lower than the target air pressure value, and the time expenditure caused by the step-by-step deflation is effectively reduced. In addition, after the air pressure of the inflatable object is lower than the target air pressure value, the air pressure of the inflatable object is reversely regulated through a controllable air charging process, so that the accurate regulation of the air pressure value of the inflatable object is facilitated, and the contradiction between the regulation speed and the regulation precision in the traditional stepping regulation mode is solved.

Description

Air pressure adjusting method and air pressure adjusting device for inflatable object Technical Field The embodiment of the application relates to the technical field of air pressure control, in particular to an air pressure adjusting method and air pressure adjusting equipment for inflatable objects. Background Currently, in daily use of various inflatable objects (such as balls, tires, inflatable mats, etc.), the internal air pressure of the inflatable objects is usually required to be regulated to be within a specific pressure range through an inflation operation and a deflation operation so as to meet basic use performance and safety requirements. In some applications, it is desirable to relatively accurately adjust the internal air pressure of an inflatable object to a particular target air pressure value (e.g., for professional ball games such as football, rugby, or basketball). For rapid and convenient adjustment, an air pressure adjustment device is generally used, and the internal air pressure of the inflatable object is brought to a set target air pressure value by means of closed-loop control. When the air pressure regulating device discharges the air in the inflatable object through the air release valve or the air release channel, the air pressure regulating device is limited by factors such as higher air flow speed, relatively severe internal air pressure change, sampling performance of the air pressure sensor and the like, the conventional air pressure regulating device usually adopts a gradual approximation strategy, repeatedly releases air in smaller air release amount for a plurality of times, re-detects the air pressure after each air release, and then determines whether to continue to release according to the detection result so as to enable the air pressure of the inflatable object to approach a set target air pressure value. Such a step deflation adjustment has limitations in terms of speed and accuracy. On the one hand, when higher air pressure adjustment accuracy is required, only the single deflation amount can be set smaller, and the number of deflation steps is increased, while measurement and judgment are made between each step, which results in a significant increase in adjustment time. On the other hand, if the air release step is decreased and the single air release amount is increased in order to increase the adjustment speed, the effect of successive approximation is weakened, and the deviation between the finally achieved air pressure value and the target air pressure value is increased. Disclosure of Invention The application provides an air pressure adjusting method and air pressure adjusting equipment of an inflatable object, and aims to solve the defect that the existing air pressure adjusting equipment cannot achieve both adjusting speed and air pressure adjusting precision. In a first aspect, embodiments of the present application provide a method of air pressure adjustment of an inflatable object. The air pressure adjusting method comprises the steps of determining a target air pressure value, discharging air in the inflatable object to enable the air pressure value of the inflatable object to be reduced, and supplementing air to the inflatable object when the air pressure value of the inflatable object is lower than the target air pressure value. The air pressure adjusting method has the advantages that when the air pressure value of the inflatable object needs to be reduced to the target air pressure value, the air pressure value of the inflatable object is greatly reduced, the inflatable object spans the target air pressure value and falls into a range lower than the target air pressure value, and time expenditure caused by step-by-step deflation is effectively reduced. Moreover, by utilizing the characteristic that the air pressure change in the air inflation process is relatively easier to control, after the air pressure of the inflatable object is lower than the target air pressure value, the air pressure value of the inflatable object is regulated reversely through the controllable air inflation process, so that the accurate regulation and control of the air pressure value of the inflatable object can be realized, and the contradiction between the regulation speed and the regulation precision of the stepping regulation mode can be well solved. In a second aspect, embodiments of the present application provide an air pressure regulating device. The air pressure adjusting device comprises an air inflation executing mechanism, an air discharge executing mechanism and an air pressure sensor, wherein the air inflation executing mechanism is configured to execute air inflation operation and supplement air to an inflatable object through a connecting pipeline, the air discharge executing mechanism is configured to execute air discharge operation and discharge air in the inflatable object through the connecting pipeline, the air pressure sensor is configured to collec
