Abstract

An inflating/deflating device in combination with an inflatable mattress having multiple chambers includes a casing with an inlet and three outlets, a pump received in the inlet to provide inflation/deflation to the chambers of the inflatable mattress and multiple controllable valves respectively and movably mounted on the outlets such that the pump is able to inflate/deflate the chambers of the inflatable mattress simultaneously.

Claims

1. An inflating device provided to an inflatable mattress having multiple chambers to inflate the multiple chambers simultaneously or separately, wherein the inflating device comprises:

a case built in the inflatable mattress and having at least one inlet and multiple outlets corresponding to the multiple chambers;

a pump connected to the at least one inlet to provide inflation to the multiple chambers of the inflatable mattress; and

multiple controllable valve elements, each having at least one spring, an electromagnetic switch and a controllable valve, connected to the corresponding outlets such that the pump is able to inflate/deflate the multiple chambers of the inflatable mattress simultaneously or separately;

wherein said multiple controllable valve elements control the movement of the respective controllable valve to open/close the outlet.

2. The inflating device in combination with an inflatable mattress having multiple chambers as claimed in claim 1 further comprising a master switch provided to control movement of the at least one electromagnetic switches of the valves.

3. The inflating device in combination with an inflatable mattress having multiple chambers as claimed in claim 1, wherein an inflate switch and a deflate switch are provided to respectively control an inflation and a deflation functions of the pump.

4. The inflating device in combination with an inflatable mattress having multiple chambers as claimed in claim 1, wherein a wire control mechanism is provided to control the movement of the valves.

5. The inflating device in combination with an inflatable mattress having multiple chambers as claimed in claim 1, wherein a wireless control mechanism is provided to control the movement of the valves.

6. The inflating device in combination with an inflatable mattress having multiple chambers as claimed in claim 1, wherein the pump both provides inflation and deflation to the multiple chambers of the inflatable mattress.
