Impeller apparatus and air blowing device

A blowing device comprising:

• an enclosure;
• an air inlet and an air outlet formed at the enclosure;
• and
• an impeller apparatus arranged in the enclosure and including:
• a housing including:
• an air duct formed in the housing, the air duct being in communication with the air inlet and the air outlet, and including a first air duct and a second air duct successively connected to each other, and the second air duct having a non-blocking area;
• a first side plate;
• a second side plate;
• and
• a first end plate arranged between and configured to connect a first end of the first side plate and a first end of the second side plate, the first end plate being formed with an open groove, the open groove extending to an edge of the first end plate and being formed with an opening at the edge of the first end plate;
• an impeller arranged in the first air duct;
• a heat generation member rotatably arranged in the second air duct, the heat generation member including a heat generation body and a shaft member at one end of the heat generation body, the shaft member being configured to be interposed into the open groove from the opening, and the heat generation member having:
• a blocking state in which the heat generation member blocks the second air duct;
• and
• a non-blocking state in which the heat generation member is accommodated in the non-blocking area and does not block the second air duct;
• and
• a driving mechanism connected to the shaft member and configured to drive the shaft member.
