 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 2, an airbed 26 of a first embodiment of the present invention is provided with a detachable electric pump 20, a built-in battery case 22 and a built-in socket 24. The battery case 22 has a cover 221 on which electrodes 222 are provided. Also, on the bottom of the battery case 22 are provided electrodes 223 corresponding to the electrodes 222 of the cover 221. An O-ring 244 and an electrode 242 are provided on the inner wall of the socket 24, wherein the electrode 242 is electrically connected to the electrodes 222, 223 of the battery case 22. Furthermore, the electric pump 20 is substantially cylindrical and has an electrode 202 on its side surfaces, an air inlet 204 and an air outlet 206 on its ends and a check valve 208 inside. The check valve 208 of the electric pump allows air to flow in a single direction from the inlet 204 to the outlet 206.

In operation, batteries are loaded into the battery case 22. The electric pump 20 is fitted into the socket 24 and then rotated so that the electrode 202 of the electric pump 20 contacts the electrode 242 of the socket 24. Then, the electric pump 20 is actuated to pump outside air into the airbed 26 as shown in FIG. 3A. The O-ring 242 in the socket 24 prevents the airbed 26 from leaking. In deflating operation, the user detaches the electric pump 20 from the socket 24 to deflate the airbed 26, as shown in FIG. 3B.

It is understood that the O-ring can be provided on the side surfaces of the electric pump 20 instead of in the socket 24 to prevent the airbed from leaking.

Referring to FIG. 4, an airbed of a second embodiment of the present invention is provided with a detachable electric pump 30, a cap 37 for the electric pump 30, a built-in battery case 32 and a built-in socket 34. The battery case 32 has a cover 321 on which electrodes 322 are provided. Also, on the bottom of the battery case 32 are provided electrodes 323 corresponding to the electrodes 322 of the cover 321. Furthermore, an arrow symbol 36 is marked on the airbed and besides the socket 34. Flanges 342 are formed at the rim of the socket 34, while electrodes 344 are provided on the inner wall of the socket 34 and are electrically connected to the electrodes 322, 323 of the battery case 32. Furthermore, the electric pump 30 is substantially cylindrical and has a flange 301 on its side surfaces, two electrodes 302 provided on the flange 301, an air inlet 304 and an air outlet 306 on its ends. Also referring to FIG. 5, symbols “on”, “off” and “open” are marked on the side surfaces and the end of the electric pump 30.

In operation, batteries are loaded into the battery case 32 to supply the electric pump 30 with the power. The electric pump 30 in this embodiment is used to inflate or deflate the airbed. In inflating operation, the electric pump 30 is fitted into the socket 34 with the air outlet 306 inside the airbed and the air inlet 304 outside the airbed. The electric pump 30 is rotated to change the positions of symbols “on”, “off” and “open”. When the arrow symbol 36 points at the symbol “on” as shown in FIG. 6A, the electrodes 302 of the electric pump 30 contact the electrodes 344 of the socket 34 to actuate the electric pump 30. Then, outside air is pumped into the airbed as shown in FIG. 6B. When the arrowsymbol 36 points at the symbol “off”, the electric pump 30 is stopped. When the arrow symbol 36 points at the symbol “open”, the electric pump 30 is detachable from the socket 34. FIG. 6C depicts the airbed full of air, wherein the air outlet of the electric pump 30 is closed by the cap 37 to seal the airbed after the inflating operation.

In deflating operation, the electric pump 30 is reversely fitted into the socket 34, with the air inlet 304 inside the airbed and the air outlet 306 outside the airbed. The electric pump 30 is rotated to change the positions of symbols “on”, “off” and “open” on its side surfaces. When the arrow symbol 36 points at the symbol “on” as shown in FIG. 7A, the electrodes 302 of the electric pump 30 contact the electrodes 344 of the socket 34 to actuate the electric pump 30. Then, air inside the airbed is pumped out as shown in FIG. 7B. When the arrow symbol 36 points at the symbol “off”, the electric pump 30 is stopped. When the arrow symbol 36 points at the symbol “open”, the electric pump 30 is detachable from the socket 34.

In either of the inflating and deflating operations, the flanges 342 of the socket 34 are used for confining the flange 301 of the electric pump 30, thus preventing the electric pump 30 from separating with the socket 34 when the arrow symbol 36 points at the symbols “on” and “off”. However, the flanges 342 are spaced apart at the rim of the socket 34 to avoid confining the flange 301 of the electric pump 30 when the arrow symbol 36 points at the symbol “open”. Thus, the electric pump 30 is detachable from the socket 34 when the arrow symbol 36 points at the symbol “open”.

While the invention has been described by way of example and in terms of the preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
