ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to an inflation seat assembly, more particularly to an inflation seat assembly for connecting an inflatable article to a motor-driven air pump.
2. Description of the Related Art
Referring to
FIG. 1
, a conventional inflatable article
100
is generally provided with an inflation valve
200
. Air is supplied into the inflatable article
100
by blowing or by a motor-driven air pump
300
. The inflation valve
200
is a check valve that can prevent the air in the inflatable article
100
from escaping via the inflation valve
200
.
Since the inflation valve
200
has a very simple construction, it cannot be relied upon to effectively achieve the purpose of preventing the air in the inflatable article
100
from escaping. Furthermore, since the inflation valve
200
is relatively small, coupling of the air pump
300
to the inflation valve
200
for supplying air into the inflatable article
100
is inconvenient to conduct.
SUMMARY OF THE INVENTION
Therefore, the main object of the present invention is to provide an inflation seat assembly that is capable of overcoming the aforementioned drawbacks of the prior art.
Another object of the present invention is to provide an air inflatable assembly that is clear of the aforementioned drawbacks of the prior art.
According to one aspect of this invention, there is provided an inflation seat assembly adapted for connecting an inflatable article to a motor-driven air pump. The air pump has an air inlet port and an air outlet port, and is operable so as to draw air via the air inlet port and to supply air via the air outlet port. The inflation seat assembly comprises a casing, an inlet check valve, an air outlet, and a closure member. The casing has a base wall, a peripheral wall extending in a transverse direction from a periphery of the base wall, and a skirt flange extending outwardly from the peripheral wall. The base wall and the peripheral wall cooperate to form a receiving space that is adapted to retain the air pump removably therein. The casing is adapted to be extended into the inflatable article, and is adapted to be connected sealingly to the inflatable article such that the receiving space is accessible externally of the inflatable article. The inlet check valve is disposed on the base wall, is adapted to be coupled to the air outlet port of the air pump, and permits air flow from the air outlet port into the inflatable article for inflating the inflatable article. The air outlet is formed in the skirt flange, and is adapted to be in fluid communication with an interior of the inflatable article. The closure member is mounted on the air outlet for closing selectively the air outlet.
