Definitions
- the present invention relates generally to pumps, More specifically: the present invention relates to a pump with an integrated deflation valve.
- Inflatable mattresses have become popular due to their utility as an extra bed needed around the house or on camping trips.
- An advantage of such inflatabie mattresses is that they are portable and easily stored.
- a pump is typically required to fill these mattresses quickly and efficiently.
- a battery-operated or corded pump may be provided with the mattress and adapted to fill the mattress with air.
- the pump is integrated into the air mattress, !n this case, the perimeter of the pump is glued or welded to the mattress.
- a separate deflation port is also glued or welded to the mattress.
- An embodiment of a pump for an inflatable device includes a housing that defines a blower chamber configured to be inserted into the inflatable device.
- the blower chamber includes an exhaust port configured to communicate air out of the pump.
- the housing also defines a deflation port, which is adjacent to the blower chamber, and an attachment portion configured to make a substantially airtight seal with the surface of the inflatable device.
- the pump also includes a removably attachable cover configured to substantially cover the blower chamber. The cover defines an opening through which the deflation port extends, and at least one vent through which air is communicated into the pump.

- the blower chamber 110 of the pump 100 is configured to be inserted into the inflatable device 500 such that the blower chamber 1 10 is substantially disposed inside the inflatable device 500, as illustrated in Fig. 5.
- the blower chamber 110 defines a cavity 310 configured to house a blower housing 305.
- the blower housing 305 may comprise an impeiler 410, an AC or DC electric motor 415, an air inlet 420, and an air outlet 425.
- the electric motor 415 may be coupled to the impeller 410 via a shaft (not shown),.
- the blower housing 305 is configured to communicate air from vents 129 defined by the cover 125 to an exhaust port 115 (Fig. 1) of the blower chamber 110. to pressurize the inflatable device 500 with enough pressure to enable the support of an object, such as a person.
- Air is drawn into the blower housing 305 via the air inlet 420 and exits the biower housing 305 via the air outlet 425.
- the air outlet 420 is configured to form a substantially air tight seal with the exhaust port 1 15, which may include a receiving portion 312 ⁇ Fig. 3) that is configured to be complementary to the air outlet 420.
- the exhaust port 115 is configured to
- the exhaust port 115 is configured to provide unidirectional air flow into the inflatable device 500.
- the exhaust port 115 may include a valve membrane 103 that deflects to allow air to move into the inflatable device 500 and seals against a surface to prevent air from escaping from the inflatable device 500.
- a grili may be disposed around the valve to prevent mechanical interference with the valves operation.
- the valve may comprise a flexible material, such a rubber, silicone, or a different material capable of performing the function of the valve.
- the valve 1 15 is configured to be removably attached to the blower chamber 310.
- the vaive is inserted into the biower cavity 310, pushed into an opening defined by the biower chamber 110 and twisted to secure the vatve 115 to the blower chamber 110. The vaive may be removed by reversing these steps.
- a pressure regulator (not shown) may be disposed within the blower chamber 1 10.
- the pressure regulator is configured to interrupt power to the motor 415 of the blower housing 305 when a desired air pressure is achieved inside of the inflatable device 500.
- the pressure regulator may be removably attached to the blower chamber 1 10 to enabie removal of the pressure regulator.
- the deflation port 140 of the housing 102 may be positioned adjacent to the blower chamber 110.
- the deflation port 140 enables the deflation of the inflatable device 500.
- a detachable deflation port cap 120 may be secured to the deflation port 140 to prevent air from escaping from the inflatable device 500.
- At least one advantage to providing a housing with a unified blower chamber 1 10 and deflation port 140 is that it minimizes the number of items glued or welded to the inflatable device 500, thereby decreasing the costs associated with manufacturing the inflatable device 500.
- Another advantage of a housing with a unified blower chamber 110 and deflation port 140 is that the surface area for the associated attachment portion 105 is less than the surface area for respective attachment portions of a comparably sized non-unified blower chamber and deflation port. The decreased surface area lowers the likelihood of a leak developing in the inflatable device 500 in the vicinity of the pump 100.
- the deflation port cap may include locking members 120a that are configured to engage complementary locking members 140a on the deflation port 140.
- the deflation port cap 120 may include a seal 120b, such as a rubber o-ring, to improve the air-tightness between the deflation port 140 and the deflation port cap 120.
- the deflation port cap 120 is tethered to the deflation port 140 to prevent
- the deflation port cap 120 and/or the deflation port 140 may each define an aperture (not shown) for securing the tether 130,
- the deflation port 140 includes a vafve 140b, as shown in Fig. 2B.
- the valve 140b is configured to substantially prevent air in the inflatable device 500 from escaping through the deflation port 140 when the deflation cap 120 is removed.
- the vaK/e 140b may comprise a flexible material, such as rubber, silicone, or a different material and is configured to form a substantially airtight seal with an inner surface of the deflation port 140 when the air pressure inside the inflatable device is greater than the surrounding air pressure.
- the valve 140b is opened by pushing the valve 140b in an inward direction, in some implementations, the valve 140b is configured to be selectively locked in an open position by pushing the valve 140b over retention members 142 of the deflation port 140, as illustrated in Fig. 1 B.
- the valve 140b may include a member 140c that enables returning the valve to a closed position.
- the cover 125 is configured to be removably attached to the housing 102 via fasteners, such as screws, or may be removable attached in a different manner.
- the cover 125 and/or housing 102 may include locking members that enabie snapping the cover 125 into place.
- the cover 125 is configured to substantially cover the cavity 310 defined by the blower chamber 110.
- the cover 125 may define one or more vent openings 129 through which air is communicated into the blower chamber 110, and an opening 127 through which the deflation port 140 extends.
- the cover 125 may include one or more bosses 405 thai enable fastening the blower housing 305 to the cover 125.
- the blower housing 305 may be fastened to the cover 125 via screws that enable removai of the blower housing 305 for servicing.
- Re!easable connectors may be utilized to connect the motor to other circuits so that the blower housing 305 may be easily removed.
- the cover 125 with the fastened blower housing 305 may be fastened to the housing 102,
- At least one advantage to providing a removably attached cover is that it enables placement or repiacement of the blower housing 305 and other components that are disposed within the blower chamber 1 10 without the destruction of the inflatable device 500.
- the housing 102 may be inserted and fastened to the inflatable device 500 in a first manufacturing operation. Then components of the pump 100 may be inserted into the blower chamber 110. TO service the tnflatabie device 500, the cover may be removed to expose the blower housing 110, the valve 1 15, pressure regulator, and other components disposed within the blower chamber 1 10. The respective components may then be serviced.
- cover 125 may be customized independent of the other components of the pump.
