Abstract: A nozzle for fast inflation and deflation includes a flexible plastic body, an air tube, and a sealing plug. The flexible plastic body is connected to a bottom of the air tube, and the sealing plug is flexibly connected to an outer port of the air tube. A valve sheet is in the flexible plastic body. For air inflation or deflation, a gap as an air channel is formed between the valve sheet and the air tube for inflation or deflation without pressing the flexible plastic body. To store air, the air tube is bent downward until the flexible plastic body is deformed to cause the valve sheet to contact the inner port of the air tube so as to avoid air leakage. Then, the air tube is allowed to be slowly plugged by the sealing plug. The problem of internal air leaking out is thus fully solved.

Abstract: An air pump capable of automatic air supplements has a housing, a low-pressure blower, a high-pressure blower, a first auto-stop controller, and a second auto-stop controller. The low-pressure blower is used to inflate an inflatable article with low-pressure air and allows the air pump to stop working during inflation automatically. The high-pressure blower is used to inflate an inflatable article with adjustable high pressure air, so that the inflatable article can have a hardness suitable for a user's need, and allows the air pump to stop working automatically during inflation or to supply air automatically during inflation. The air pump can stop working automatically and can supply air automatically without manual work, and can inflate the inflatable article to the hardness suitable for the user's need conveniently.

Abstract: The present invention provides an external automatic control smart air pump, including a housing, an air blast device and an automatic control mechanism. By setting up the intake nozzle in such way that the second cavity is independently in communication therewith, the actual air pressure inside the inflatable object can be precisely measured. The fine motion switch is controlled with the coordination of the push button, rotating position limiting member, pressing member, air pressure sensing film, first restoring spring and second restoring spring, thereby realizing the auto stop control of the air pump. The structure of the present invention is simple, and the assembling process thereof is convenient. In addition, the present invention can be precisely controlled according to the actual air pressure inside the inflatable object, thereby bringing convenience for the user.

Abstract: An inflation device has a housing, a check valve assembly, and a filtering cover. The check valve assembly is mounted inside the housing by threads, and the filtering cover covers an external wall of the housing. The check valve assembly has a body, a valve stem, a plate, a spring, and a first gasket. With resilience of the spring, the valve stem, the plate and the first gasket move axially inside the body for opening or closing the check valve assembly. The filtering cover prevents an inflatable mattress from air leakage caused by fiber blocking the check valve assembly. The filtering cover is detachably mounted in the housing for assembling flexibility according to demand. Since the diameter of each hole of the filtering cover is less than 2 mm, the fibers cannot pass through the holes to enter a passage of the body.

Abstract: A rotary adjustment controller of an air pump has a casing, a micro switch, an air pressure sensing film, and a control mechanism. The control mechanism has a bolt, a nut, and a turning button. The nut is screwed on the bolt. The micro switch is securely mounted on and moves along with the nut. The turning button selectively drives the bolt to rotate. With turning the turning button to rotate the bolt, the micro switch selectively departs from or approaches the air pressure sensing film. Positions of the micro switch are adjusted steplessly, so an inflatable article can be inflated to a desired hardness. The rotary adjustment controller has simplified structure and can be operated conveniently and rapidly.
