Abstract
An inflator has a tubular housing, an adaptor, a cover, and an inflation mechanism. The tubular housing is made of plastic and has two opposite ends. The adaptor is made of metal and disposed on one of the two opposite ends of the tubular housing. The cover is made of plastic and welded with said one of the two opposite ends of the tubular housing to limit a position of the adaptor. The inflation mechanism is disposed to the interior space and is operable to pump air to flow from the interior space, through the adaptor, and to an exterior of the tubular housing. The cover and the tubular housing welded with each other have a same material, which prevents air leakage due to fracture and stabilizes quality of the inflator.
Claims9
An inflator comprising:
- a tubular housing made of plastic, having a first end and a second end opposite to each other, and being hollow to form an interior space;
- an adaptor made of metal and disposed on the tubular housing;
- a cover made of plastic and welded with the tubular housing to limit the adaptor on the first end of the tubular housing;
- and
- an inflation mechanism disposed to the interior space and being operable to pump air to flow from the interior space to an exterior of the tubular housing through the adaptor;
- wherein
- the adaptor has a first cylindrical post portion and a second cylindrical post portion connected to each other,
- the first cylindrical post portion has an outer diameter larger than an outer diameter of the second cylindrical post portion;
- the cover has an opening having a diameter smaller than the outer diameter of the first cylindrical post portion and larger than the outer diameter of the second cylindrical post portion,
- the second cylindrical post portion is inserted in the opening of the cover;
- the first cylindrical post portion is limited in the tubular housing by the cover;
- the tubular housing has a tubular housing opening and an annular wall surrounding the tubular housing opening on the first end of the tubular housing;
- the first cylindrical post portion of the adaptor is disposed in the tubular housing and surrounded by the annular wall, and
- the second cylindrical post portion of the adaptor protrudes from the tubular housing opening to be inserted in the opening of the cover.
