1. An electric steamer, comprising: a steamer cover,at least one steamer chamber that is covered by said steam cover,a fluid receiving unit having a water inlet and a gas outlet,a base, wherein said steam cover, said steam chamber, said fluid receiving unit are sequentially arranged from a top to a bottom of the electric steamer, wherein said base has a heating unit, a water chamber communicating with said water inlet of said fluid receiving unit, and a control circuit provided in said base, wherein said base further comprises a pressure sensor and a pressure sensor inlet pipe connected to said fluid receiving unit, wherein said pressure sensor, which is provided at said pressure sensor inlet pipe, has a signal output terminal connected to said control circuit through a connecting wire, anda partition member provided on top of said heating unit, wherein said heating unit is arranged for heating up water within said partition member to generate steam to flow into said steam chamber through said gas outlet of said fluid receiving unit. 2. The electric steamer, as recited in claim 1, further comprising a steam arrangement between said pressure sensor inlet pipe and said fluid receiving unit, wherein said steam arrangement comprises a steam channel and a pressure detecting chamber, wherein said pressure sensor inlet pipe is mounted inside said pressure detecting chamber, wherein an upper end of said steam channel is connected to said fluid receiving unit, wherein said pressure detecting chamber has a chamber inlet connected to said steam channel. 3. The electric steamer, as recited in claim 2, wherein said fluid receiving unit further comprises a stair-shaped member provided at a bottom portion thereof, wherein said upper end of said steam channel is connected within said stair-shaped member. 4. The electric steamer, as recited in claim 2, wherein said chamber inlet is positioned towards a bottom portion of said pressure detecting chamber, wherein said chamber inlet is positioned at a level higher than a maximum water level of said water chamber. 5. The electric steamer, as recited in claim 2, wherein said steam channel has a water returning hole provided at a bottom end of said steam channel, wherein said water returning hole is positioned at a level lower than a minimum water level of said water chamber. 6. The electric steamer, as recited in claim 2, wherein said steam arrangement further has a residual gas outlet provided at an upper end of the steam channel, wherein said residual gas outlet is positioned at a level higher than the maximum water level of said water chamber. 7. The electric steamer, as recited in claim 2, wherein said pressure detecting chamber further comprises a chamber partition panel, wherein said chamber partition panel divides said pressure detecting chamber into two chamber compartments, wherein said chamber inlet and said pressure sensor inlet pipe are provided in said two chamber compartments respectively, wherein said chamber partition panel has a partition hole provided at a bottom portion of said chamber partition panel such that said two chamber compartments are capable of communicating with each other. 8. The electric steamer, as recited in claim 7, wherein an upper end of said inlet pipe is positioned at a level higher than that of an upper end of said partition hole. 9. The electric steamer, as recited in claim 2, wherein an upper end of said inlet pipe is positioned at a level higher than that of an upper end of said chamber inlet. 10. The electric steamer, as recited in claim 7, wherein said inlet pipe is outwardly extended from a bottom surface of said pressure detecting chamber. 11. The electric steamer, as recited in claim 9, further comprising a temperature sensor in said steam chamber. 12. The electric steamer, as recited in claim 9, further comprising, a protruded ring I and a water groove I provided at a connecting junction between said steamer cover and said steam chamber. 13. The electric steamer, as recited in claim 9, further comprising a protruded ring II and a water groove II provided at a connecting junction between said steam chamber and said fluid receiving unit. 14. The electric steamer, as recited in claim 1, wherein said inlet pipe is outwardly extended from a bottom surface of said fluid receiving unit.
