Blade adjustment mechanism and air circulator

An air circulator, comprising a housing, a cross-flow wind wheel and a blade adjustment mechanism located above the cross-flow wind wheel, the cross-flow wind wheel being fixedly connected with the housing, the housing defining an air outlet, wherein the blade adjustment mechanism comprises:

• a fixing bracket, fixedly connected with the housing and defining a sliding space;
• at least two adjustment members, a part of each of the at least two adjustment members being accommodated in the sliding space and being slidably connected with the fixing bracket, each of the at least two adjustment members defining a first adjustment slot at an end adjacent to the air outlet;
• and
• at least two first wind deflectors, a part of one of the at least two first wind deflectors being configured to extend into the air outlet and being rotationally connected with the fixing bracket, a part of one of the at least two first wind deflectors facing away from the air outlet being movably accommodated in the first adjustment slot;
• wherein the at least two adjustment members are driven to move away from or move closer to each other, the first adjustment slot being configured to drive one of the at least two first wind deflectors to rotate to make the air outlet blow divergently or in a concentrated manner.
