Patent ID: 7182094

Claim:
A nozzle through which air can be pumped into a cushion from a pump, the nozzle comprising: a housing comprising a passage extending therein and a space intersecting the passage at a nonparallel angle of less than 90°; a core put in the space in a sealing and sliding manner and including a first end and a second end, with the second end for pushing a valve installed in the cushion, wherein the core defines a passage extending from the second end towards but spaced from the first end, at least one peripheral hole via which the passage thereof is communicated with the space of the housing and a slot formed on the second end and communicated with the passage thereof, with the peripheral hole being within an extent of the passage of the housing; a tubular lip installed on the housing in a sealing and rotating manner, wherein the tubular lip includes a tubular portion integrally formed as a single unseperable component with a neck portion, with the neck portion having an internal face and a thread formed on the internal face for engagement with a thread formed on the cushion; a collar installed rotationally on the housing, wherein the collar includes a thread formed on an external face, wherein the tubular portion of the tubular lip includes a collar thread formed on the internal face for engagement with the thread of the collar, with the collar thread having a larger diameter than the thread formed on the internal face, wherein the housing includes an annular flange formed thereon and sandwiched between the collar and the tubular lip, with the collar threadably engaged with the tubular lip both rotatable on the housing for threadably engaging the thread formed on the internal face with the thread formed on the cushion, with the thread formed on the internal face aligned with and having a diameter smaller than the space of the housing; a control element including a cam installed pivotally on the housing for pushing the core and a lever extending from the cam for rotating the cam; and a tubular seal fit in the space of the housing for abutting with the internal face of the tubular lip and therefore sealing the cushion, with the tubular seal including a hole, with the second end of the core moveably received in the hole of the tubular seal, with the tubular seal being sandwiched in the space of the housing during engagement of the collar thread of the tubular lip with the thread of the collar.
