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: A water gun is revealed. The water gun includes a jetting outlet and at least one suction inlet. The jetting outlet is disposed on a front plate of a barrel of the water gun while the suction inlet that works like a one-way valve is arranged around the jetting outlet. When the hand grip is pulled out, water outside is drawn into an inner space of the barrel of the water gun through the at least one suction inlet. The water in the inner space of the barrel of the water glue is unable to flow out through the at least one suction inlet when the hand grip is pushed in. Moreover, an inner thread is arranged outside the jetting outlet and used for connecting a ball inflating needle or a bike pump hose for inflation of inflatable toys or balls.

The first auto-stop controller has simplified structure and inflates the inflatable article without manual work, which is a great convenience to users.

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: 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.

Abstract: An auto-stop air pump has a housing, a blower and an auto-stop device. The housing has an upper chamber, a lower chamber, a main inlet and an outlet. The upper chamber and the lower chamber communicate with each other. The main inlet and the outlet are formed through the housing respectively and communicate with the upper chamber. The blower is mounted in the housing and has a motor connected to a dual-sided impeller. The auto-stop device is mounted in the housing and has a shell, a film, a micro switch and an actuating unit. The film and the micro switch are mounted in the shell. The actuating unit is mounted movably through the shell. Owing to deformation of the film by pressure, the film presses the micro switch to close the micro switch so the air pump can stop working automatically.

Abstract: An inflating valve has a body and a valve disk. The body is hollow and has a passage defined through the body and a holding tab. The passage has an inner surface and a bottom opening defined in the bottom of the body. The holding tab is radially connected to the inner surface of the passage and has a holding hole defined through the holding tab. The valve disk is attached securely to the bottom of the body to close the bottom opening of the passage and has a holding rod formed on and protruding from the valve disk and engaging the holding hole in the holding tab. Accordingly, the valve disk can be automatically opened by the pressured air and automatically closed by the recoil force provided by the holding tab.

Abstract: An air pump for an inflatable article has a housing, and a blower, a switch assembly, an air valve and a fan guard mounted in the housing. The switch assembly has a slider and a driving device sliding the slider and the air valve to switch operating modes of the air pump. Thus, the air pump inflates or deflates the inflatable article or maintains or fine-tunes the air pressure inside the inflatable article. Therefore, the first and second openings of the housing are disposed on the housing for connection to different kinds of inflatable articles and the airflow directly flows through the air pump so inflating and deflating the inflatable article is fast.
