Embodiment Construction
[0031] The illustrated example of the present invention provides a pressure regulator that can automatically inflate, automatically deflate, or both. Many new products can be made from this pressure regulator, such as automatic tire valves with adjustable pressure, valve extension rods for tire inflation, and so on. These devices are user-friendly, and tire inflation or deflation is simple, quick and accurate. When in use, the user only needs to preset the pressure value recommended by the vehicle manufacturer on the regulator, then connect the inlet of the regulator to a high-pressure air source (such as a compressed air tank or an air pump), and connect the outlet to a tire to inflate or The deflation is automatic; once the tire pressure reaches the preset value, the inflation or deflation will be automatically terminated.

The invention provides a user-friendly voltage regulator and its usage. The pressure regulator can be used to connect the pressure from an inflatable object, which includes: (1) a hollow body; (2) a valve system, which is located in the hollow body; (3) a fluid inlet; (4) a (5) a fluid conduit, which is located in the hollow housing, between the fluid inlet and the outlet; (6) a pressure sensing structure (such as a piston), which is attached to the conduit and can be connected to the hollow housing The body moves along the length direction; (7) a pressure generating structure, which is located in the hollow shell and attached to the pressure sensing structure. The pressure generating structure can generate a biasing force acting on the pressure sensing structure, which is proportional to the desired pressure inside the inflatable object. When the initial pressure inside the inflatable object is lower than the desired pressure, the pressure regulator can inflate the object; and when the internal pressure of the object reaches the desired pressure, the pressure regulator can automatically stop the inflation. In some instances, the pressure regulator can also deflate the inflatable object when the initial pressure inside the object is higher than the desired pressure, and the pressure regulator can automatically release the pressure when the object reaches the desired pressure. Stop deflation.
Description
field of invention [0001] The present invention relates to a device and method for inflating or deflating an inflatable object such as a tire. Background technique [0002] Vehicle tire pressure plays a very important role in tire life and fuel economy. Properly inflated tires save fuel, reduce pollution, provide a comfortable and safe ride, and keep them running for years. Improperly inflated tires can accelerate tire wear, waste fuel, and cause crashes. Tires that are either over- or under-inflated can greatly shorten tire life; under-inflated tires often result in wasted fuel. [0003] Most tire inflation methods are generally a trial and error method, which is time-consuming, labor-intensive, and annoying. For example, a commonly used method is to use a tire pressure measuring device and an air pressure source to fill the tire for a while and measure the pressure; Repeat this many times until the tire pressure reaches the desired value. Another method that is not co...
