However, in the conventional double-layer inflow bellows structure, the inner circulation air door and the outer circulation air door are independently arranged, so that the interference during working is prevented, a reasonable distance is reserved between the two air doors, the overall design of the bellows structure is large, the design concept of light weight is contradicted, the weight and the volume are large, and energy is consumed. Meanwhile, in order to realize a double-layer flow mode of the blower impeller, the upper impeller and the lower impeller are separated by a circular plane baffle; in order to realize air intake of the lower impeller, a plurality of upright posts are used between the lower impeller and the blower motor to jack up the impeller to form a flow channel. This design suffers from the following disadvantages: firstly, a certain distance (upright post) is formed between the impeller and the end face of the blower motor, which is about 1/4-1/3 of the total length of the impeller, so that the dimension distance between the impeller and the volute structure of the assembly part is increased in the height direction, the volume of the whole air conditioning box is increased, the weight is increased, and the current light weight and energy saving requirements are not facilitated; secondly, the blower impeller and the blower motor are complex to assemble, and the shaking amount at the top of the impeller becomes large due to the increase of the height of the blower impeller, so that the dynamic balance difficulty is increased due to the vibration caused by the shaking, and the product qualification rate is reduced.
