20100247356 | Air pump for air mattress - An air pump manually rotated to inflate and deflate an air mattress has a housing, a first and a second air vents mounted on the housing, an air valve selectively actuated to block or open the second air vent, and a mounting rack in the housing. The mounting rack is rotated so that a first or a second air compartment in the mounting rack is aligned with the second air vent, and the air valve is propped up by an undulant baffle on the mounting rack to switch to one of inflation, deflation and pressure hold-up modes. Given the structure of the air pump, the first and second air vents are flexibly arranged and can be respectively mounted on a top and a bottom of the housing and directly aligned with mutually. Therefore, the air path is shortened to make the inflation and deflation faster and more efficient. | 09-30-2010 |
20100278670 | AIR PUMP WITH A ONE-PIECE CYLINDER - An air pump has a one-piece cylinder and a piston assembly. The one-piece cylinder has a body, a cap, a pedal and a base formed together by injection molding and welding process. The piston assembly is mounted in the one-piece cylinder and has a rod, a handle and a piston. The one-piece cylinder is structurally firm and provides excellent hermetic characteristics. | 11-04-2010 |
20110271890 | RUDDER ASSEMBLY FOR AN INFLATION BOAT - A rudder assembly for a boat has a securing base, a rudder board and at least one engaging bolt. The rudder board is mounted detachably on the securing base and has a bottom and two rudder hooks. The rudder hooks are formed respectively on two ends of the bottom and are connected securely to the securing base with the at least one engaging bolt. The at least one engaging bolt is mounted detachably on the securing base and engages respectively at least one of the rudder hooks on the rudder board. Accordingly, a rudder board can be conveniently detached from the securing base even while an inflating boat is at an inflated condition. | 11-10-2011 |
20110272609 | Releasing valve for an inflatable object - A releasing valve for an inflatable object has a body, a valve disk and a cap. The body is body and has a passage and a disk mount. The passage is defined through the body and has a bottom opening. The valve disk is attached securely to the bottom of the body to close the bottom opening of the passage and has a mounting end and a free end. The mounting end is mounted securely on the disk mount of the body. The free end is opposite to the mounting end. The cap is attached to the body around the bottom opening, holds the valve disk inside and has a stop. The stop selectively engages the free end of the valve disk when the valve disk being pushed away from the bottom opening for discharging air out from the inflating object via the releasing valve. | 11-10-2011 |
20120042962 | INFLATING VALVE FOR AN INFLATABLE OBJECT - 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. | 02-23-2012 |
20120093662 | AUTO-STOP AIR PUMP - 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. | 04-19-2012 |
20120107157 | AIR PUMP HAVING AN IMPELLER WITH DOUBLE-SIDED BLADES - An air pump having an impeller with double-sided blades is mounted outside an inflatable product, and has a body and a blower. The body has a first air chamber and a second air chamber communicating with each other, a first air inlet and a second air inlet formed at two ends of the first air chamber, and multiple first supplement air inlets formed through the body to communicate with the second air chamber. The blower has a motor and an impeller. The impeller driven by the motor has multiple double-sided blades capable of efficiently inflating air from the multiple first supplement air inlets or deflating air from the first air inlet. The air pump achieves to be more efficient in inflating and deflating the inflatable product, and structurally simplified to facilitate production and assembly of the air pump and cost reduction in production and assembly. | 05-03-2012 |
20150198168 | Air Pump Capable of Automatic Air Supplements - 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 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. | 07-16-2015 |
