A blender includes a base unit having a receiving well, a container assembly and an actuation arrangement. The container assembly includes a container body having a blending cavity and a rim, and a connector member detachably attached on the container body to selectively seal the blending cavity, a driven unit and a blending blade. The actuation arrangement includes a plurality of actuating members outwardly extended from the rim of the container body, a plurality of actuating slots indently and spacedly formed along a side wall of the receiving well, and a plurality of actuating switches. When the connector member is slightly rotated in the receiving well, each of the actuating members is arranged to circumferentially move along the corresponding actuating slot so as to actuate the actuating switches for actuating the driving head to rotate.

1. A blender, comprising: a base unit which comprises a base body having a receiving well, a driving unit received in said base body, and a driving head connected to said driving unit and rotatably provided in said receiving well;a container assembly, which comprises:a container body having a blending cavity and a rim, said container body being sized to fittedly receive in said receiving well;a connector member detachably attached on said container body to selectively seal said blending cavity, said connector member being sized to receive in said receiving well;a driven unit operatively provided on a bottom side of said connector member, said driven unit being arranged to engage with said driving head; anda blending blade provided on a top side of said connector member, said blending blade being connected to said driven unit so that when said driven unit is driven to rotate, said blending blade is also driven to rotate in said blending cavity; andan actuation arrangement, which comprises:a plurality of actuating members outwardly extended from said rim of said container body,a plurality of actuating slots indently and spacedly formed along a side wall of said receiving well at a top inner edge portion thereof, said actuating members being received in said actuating slots respectively, each of said actuating slots having an engagement portion having a relatively greater height, and an actuation portion having a relatively smaller height, said engagement portion of each of said actuating slots having a top opening so that said engagement portions are accessible from a top side of said base body; anda plurality of actuating switches electrically connected to said driving unit and entirely received in said actuation portions of said actuating slots respectively, in such a manner that said actuating switches being in idle position before said driving unit is actuated, and when said connector member is rotated in said receiving well, each of said actuating members is arranged to circumferentially and sidewardly move along said corresponding actuating slot from said engagement portion to said actuation portion to directly engage with and automatically actuate said actuating switches so as to actuate said driving unit and said driving head to rotate after said actuating members are moved circumferentially and sidewardly in said actuating slot, each of said actuating switches having an inclined surface, a flat surface and a bulging portion formed between said slanted surface and said flat surface, said bulging portion forming a protrusion for preventing said corresponding actuating member from accidentally moving back to said corresponding engagement portion when said driving unit is actuated. 2. The blender, as recited in claim 1, wherein each of said actuating members is positioned to correspond to a position of said engagement portion of said corresponding actuating slot so that said actuating members are capable of being inserted within said engagement portions of said actuating slots respectively from a top side of said base body. 3. The blender, as recited in claim 2, wherein a height of said actuation portion of each of said actuating slots is greater than a thickness of said corresponding actuating member so that when said actuating members are inserted into said actuation portions respectively, an upward movement of said container assembly is substantially restricted by said actuating members, while said actuating switches are actuated automatically. 4. The blender, as recited in claim 3, wherein said driving head comprises a driving wheel and a plurality of driving members spacedly formed and extended on said driving wheel to divide said driving wheel into a corresponding number of driving compartments. 5. The blender, as recited in claim 4, wherein said connector member comprises a circumferential wall and a mid-support member provided within a space formed by said circumferential wall, said circumferential wall having a circular cross section for forming a ring-shaped structure, said mid-support member being provided within said circumferential wall for supporting said driven unit and said blending blade, said blending blade being supported on a top side of said mid-support member, while said driven unit being supported on a bottom side of said mid-support member. 6. The blender, as recited in claim 5, wherein said driven unit comprises a driven panel and a plurality of driven teeth spacedly formed on said driven panel to divide said driven panel into a corresponding number of driven compartments, wherein said driving members of said driving head are arranged to accommodate in said driven compartments respectively when said driving head is engaged with said driven unit. 7. The blender, as recited in claim 6, wherein each of said driven teeth has a slanted surface which is inclined to correspond to a slanted surface of said corresponding driving member so that said driving members is capable of effectively driving said driven unit to rotate when said driving head rotates. 8. The blender, as recited in claim 7, wherein said connector member further comprises a peripheral ring formed on said bottom side of said mid-support member, said peripheral ring having a circular cross section and a diameter larger than that of said driven panel, said peripheral ring being concentrically provided with respect to said driven panel. 9. The blender, as recited in claim 1, wherein said base unit further comprises a plurality of supporting pieces spacedly provided on a bottom surface of said receiving well. 10. The blender, as recited in claim 3, wherein said base unit further comprises a plurality of supporting pieces spacedly provided on a bottom surface of said receiving well. 11. The blender, as recited in claim 8, wherein said base unit further comprises a plurality of supporting pieces spacedly provided on a bottom surface of said receiving well. 12. The blender, as recited in claim 3, wherein said container body has a single external wall for forming said blending cavity within said single external wall. 13. The blender, as recited in claim 8, wherein said container body has a single external wall for forming said blending cavity within said single external wall. 14. The blender, as recited in claim 3, wherein said container body comprises an external wall panel and an internal wall panel which is sealingly coupled with said external wall panel for forming a double wall structure of said container body, said blending cavity being formed between said internal wall panel. 15. The blender, as recited in claim 8, wherein said container body comprises an external wall panel and an internal wall panel which is sealingly coupled with said external wall panel for forming a double wall structure of said container body, said blending cavity being formed between said internal wall panel.
