Embodiment Construction
[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0043] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain that it is in a specific posture (as shown in the drawings). If the specific posture changes, the relative positional relationship, movement, etc. of the components below will also change the directional indication accordingly.

The invention discloses a blade and inner rotor integrated draught fan installing structure and a draught fan. The blade and inner rotor integrated draught fan installing structure comprises an annular shell, an outer stator assembly, an inner rotor assembly and a plurality of blades. An annular installing groove is defined in the inner side of the annular shell. The outer stator assembly is arranged in the annular installing groove and comprises a stator iron core and a stator winding. The inner rotor assembly is located on the inner side of the annular shell and is in a disc shape, the innerrotor assembly is provided with a hollow part extending in the circumferential direction, and the circumferential side portion of the inner rotor assembly stretches into the annular installing grooveand is in sliding fit with the two side walls of the annular installing groove. The multiple blades are contained in the hollow part and fixedly connected with the inner rotor assembly, and accordingly the blades and the inner rotor assembly are arranged in the radial direction. According to the provided technical scheme, on the one hand, the axial size of the draught fan can be made to be smaller, and on the other hand, the stability of the inner rotor assembly is better.
Description
Technical field [0001] The present invention relates to the technical field of fans, in particular to an installation structure of an integrated fan with blades and an inner rotor, and a fan. Background technique [0002] The installation of traditional fan blades requires the installation of blades on the motor shaft, and the axial length of the motor rotor shaft needs to be extended to realize the installation of the blades, resulting in a long axial size of the fan, which is not suitable for occasions with a small axial installation space such as a vehicle. If the fan blades meet the requirements of the short axial size, the motor fan blades need to be designed outside the stator of the motor, and the motor rotor and fan blades are folded and connected through a special structure. The fan blades need to wrap the stator and rotor of the fan motor to meet the requirements. Axial small size requirements; by designing a hub shell outside the stator of the inner rotor fan, integrat...
