1. Field of the Invention The present invention relates to an inflating valve, and more particularly to an inflating valve that can close a passage automatically.
2. Description of Related Art
An inflatable object, such as a swim ring, a pneumatic boat, an inflating toy or furniture has to be inflated for use. To inflate an object, the inflatable object is connected to a pressured air source via an inflating valve that is mounted on the object. The conventional inflating valve has a valve disk closing a passage in the inflating valve to keep air in the object from leaking. When the object is inflated, the valve disk is pushed away from the passage manually to allow the pressured air to be led into and inflate the object.
However, after the object is completely inflated, the valve disk on the conventional inflating valve has also to be moved to the closing condition manually. This will cause trouble and inconvenience of operation of the conventional inflating valve.
To overcome the shortcomings, the present invention tends to provide an inflating valve to mitigate or obviate the aforementioned problems.
The main objective of the invention is to provide an inflating valve that can close a passage automatically.
The inflating valve has a body, a valve disk, a cap and a recoil member. The body is body and has a bottom, a passage and a disk mount. The passage is defined through the body and has a bottom opening defined in the bottom of the body. The disk mount is formed on the bottom of the body. 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 and holds the valve disk inside. The recoil member is mounted between the valve disk and the cap to push the valve disk closing the bottom opening of the passage in the body.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
With reference to
The body (10) is hollow, may be tubular and has an outer surface, a passage (12), a disk mount (14), an annular flange (11) and a curved recess (15). The passage (12) is defined through the body (10) and has a bottom opening defined in the bottom of the body (10) and a top opening defined in the top of the body (10). The disk mount (14) is formed on the bottom of the body (10), extends partially into the bottom opening and has at least one mounting post (141) formed on and protruding from the disk mount (14). Preferably, two mounting posts (141) are implemented. The annular flange (11) is formed around and protrudes from the outer surface of the body (10) and is connected to the inflatable object. The curved recess (15) is formed in the bottom of the body (10).
The cover (13) is mounted on the top of the body (10) in a thread manner. Preferably, the body (10) has an outer thread formed on the outer surface around the top opening, and the cover (13) has an inner thread engaging the outer thread on the body (10). The cover (13) further has an O-ring (121) mounted in the cover (10) and around the top opening of the body (10) to provide a sealing effect to the top opening of the body (10).
The valve disk (20) is rubber, is attached securely to the bottom of the body (10) with the fixing element (30) to close the bottom opening of the passage (12) and has a mounting end (21), a free end (22) and a bending groove (23). The mounting end (21) is mounted securely on the disk mount (14) of the body (10) and has at least one mounting hole (211). Preferably, two mounting holes (211) are implemented. The mounting holes (211) are defined through the mounting end (21) of the valve disk (20) and are mounted respectively around the mounting posts (141) on the body (10) to attach the mounting end (21) of the valve disk (20) onto the disk mount (14) on the body (10). The free end (22) is opposite to the mounting end (21). The bending groove (23) is defined in a side face of the valve disk (20) opposite to the bottom of the body (10) and is adjacent to the mounting end (21) to make the valve disk (20) bendable at the bending groove (23).
The fixing element (30) is attached to the bottom of the body (10) to mount the valve disk (20) on the disk mount (14) and to squeeze the mounting end (21) of the valve disk (20) between the disk mount (14) and the fixing element (30). The fixing element (30) has at least one mounting hole (31) mounted respectively around the at least one mounting post (141) on the disk mount (14) of the body (10). Preferably, two mounting holes (31) are implemented. Each mounting post (141) is mounted through the corresponding mounting holes (211,31) in the valve disk (20) and the fixing element (30) in sequence.
The cap (40) is attached to the body (10) around the bottom opening, is contained in the inflatable object, holds the valve disk (20) inside and has a top, a curved edge and multiple vents (41). The curved edge is formed on and protrudes from the top of the cap (40) and is mounted securely in the curved recess (15) in the body (10) to attach the cap (40) securely to the body (10). The vents (41) are defined through the cap (40) to allow pressured air entering into the inflatable object via the vents (41).
The recoil member (50) may be a spring, is mounted between the valve disk (20) and the cap (40) to push the valve disk (20) closing the bottom opening of the passage (12) in the body (10). In addition, the valve disk (20) further has a first spring mount (24) formed on the bottom of the valve disk (20), and the cap (40) further has a second spring mount (42) mounted on and protruding from the inner surface of the cap (40). The recoil member (50) has two ends respectively connected securely to the first and second spring mounts (24,42) on the valve disk (20) and the cap (40). Preferably, the second spring mount (42) is mounted detachably on the cap (40). The cap has a pin hole (43) defined in the cap (40). The second spring mount (42) has a mounting pin (421) formed on and protruding from the bottom of the second spring mount (42) and inserted securely into the pin hole (43) in the cap (40). Additionally, each spring mount (24,42) has an annular groove (241,422) defined in an end of the spring mount (24,42) to hold one end of the recoil member (50) inside.
To inflate an inflatable object, with reference to
After the object is completely inflated, the pressured air source is closed, and the valve disk (20) can be automatically moved/pivoted to the closing condition as shown in
