Embodiment Construction
[0012] Combine below figure 1 A detailed description will be made to the specific embodiment of the present invention.
[0013] like figure 1 The cross-flow fan blade shown is composed of a plurality of middle sections fixedly connected end to end by ultrasonic welding. The middle section is formed by integral injection molding of a ring-shaped middle plate 1 and multiple blades 5 on it. Two middle sections at the left and right ends A metal support shaft 2 is fixed at the center of the outer circular center plate 1, and the metal support shaft 2 is made of stainless steel. One of the ring-shaped middle disks 1 is provided with a magnetic ring 3 that matches the motor stator and is concentric with the metal support shaft 2. The magnetic ring 3 and the outer surface of the ring-shaped middle disk 1 are integrated by injection molding. The magnetic ring 3 Made of magnetic plastic. The magnetic ring 3 is composed of a rotating ring sleeve 31 and a connecting ring surface 32 ve...

The invention relates to an accessory on an air conditioner. A through-flow fan blade comprises a plurality of median segments connected with one another end to end, wherein the median segments are formed by performing integral injection molding on circular central disks and a plurality of blades arranged on the circular central disks; metal supporting shafts are fixed in the centers of the circles of the circular central disks on the outer sides of the two median segments on the left end part and the right end part; a magnetic ring which is matched with a motor stator and concentric with themetal supporting shaft is arranged on the outer side of one of the circular central disks; the magnetic ring and the outer side surface of the circular central disks are integrated into a whole by injection molding; the magnetic ring is made of magnetic plastic; and a magnetic ring protection ring which is connected with the circular central disk into a whole and vertical to the circular central disk is arranged along the edge of the outer side of the circular central disk. The through-flow fan blade has the advantages of novel structure, convenience for installation, low production cost, lowvibration and noise and high stability and capability of improving the use efficiency of a motor.
Description
technical field [0001] The invention relates to an accessory on an air conditioner, in particular to a cross-flow fan blade for an air conditioner. Background technique [0002] The cross-flow fan blade is one of the main accessories of the air conditioner. The cross-flow fan blade is composed of a plurality of middle sections connected end to end. The outer sides of the middle sections at both ends of the cross-flow fan blade are respectively provided with rotating steel shafts and shaft sleeve assemblies. During installation, the rotating steel shaft at one end is connected with the bearing and bearing seat on the air conditioner, and the other end is assembled and connected with the motor shaft through the shaft sleeve assembly and fixed by screws. The shaft sleeve assembly consists of a shaft sleeve, rubber parts and clips. When in use, the motor shaft drives the rotation of the cross-flow fan blade through the shaft sleeve assembly. The shortcomings of the existing cro...
