Adjustable bed system with multiple functions

A bed system, comprising:

• a frame structure;
• a plurality of platforms disposed on the frame structure;
• and
• an adjustable assembly coupled with the frame structure and the plurality of platforms for operably adjusting one or more of the plurality of platforms in desired positions;
• a plurality of fans mounted onto openings in the plurality of platforms and adapted for operably providing air circulation in a surrounding space of the bed system;
• and
• an aromatherapy system attached onto one or more of the plurality of platforms for producing desired fragrance in the surrounding space so as to promote health and well-being of a user,
• wherein the adjustable assembly comprises:
• a back lifting assembly comprising a back lifting bracket pivotally connected to the frame structure, and a back lifting actuator pivotally connected between the back lifting bracket and the frame structure for operably driving the back lifting bracket to pivotally move in an upward rotating direction or a downward rotating direction relative to the frame structure;
• and
• a leg lifting assembly comprising a leg lifting bracket pivotally connected to the frame structure, and a leg lifting actuator pivotally connected between the leg lifting bracket and the frame structure for operably driving the leg lifting bracket to pivotally move in an upward rotating direction or a downward rotating direction relative to the frame structure,
• wherein the back lifting bracket comprises a middle bar and a pair of swing arms, wherein the pair of swing arms is transversely spaced and longitudinally extended, and rigidly connected to ends of the transversely extending middle bar, and each of the pair of swing arms has a first end portion and an opposite, second end portion, wherein the first end portion of each swing arm is pivotally mounted to the frame structure;
• and
• wherein the back lifting actuator comprises a motor member, an outer tube extending from the motor member, an activation rod received in the outer tube, engaged with the motor member and configured to be telescopically movable relative to said outer tube according to a direction of motor rotation, wherein the motor member is pivotally connected to the frame structure, and the activation rod has a distal end portion pivotally connected to the middle bar of the back lifting bracket, or wherein the motor member is pivotally connected to the middle bar of the back lifting bracket, and the activation rod has a distal end portion pivotally connected to the frame structure.
