The fan housing includes a fixing plate or/and a barrel body, which are assembled through a modular and equally divided splicing structure. It helps to realize the mass production and reduce the production cost. The modular splicing structure is convenient for the mass production and capable of being assembled by welding, screw locking or snap locking, so that the entire assembling process is simplified. On the other hand, the fan motor is connected to the inner wall of the barrel body through a detachable support bracket. In addition to ease of assembling, the support bracket produced by stamping or sheet-metal working is adjustable in size, shape and quantity according to the size of the fan motor. It allows to assemble and accommodate the fan motors of different sizes and specifications in the fan housing to improve the practicability of the fan housing. Furthermore, since the fan motor is connected to the inner wall of the barrel body through the support bracket, it is helpful of improving the overall structural strength and maintaining the accommodating height, so that neither the fan motor nor the support bracket exceeds the accommodating range of the barrel body. It is also conducive to the detachable setting of the protective grid. The protective grid can be easily removed from the barrel body or changed in type, without affecting the assembly or operation of the fan motor. Certainly, since the fan housing is assembled through the modular splicing structure, the materials and the molding methods of the fixing plate and barrel body are adjustable according to the practical requirements, so as to simplify the assembling process and improve the structural strength. Moreover, it allows to strengthen the structure of fastening platform on the barrel body for fastening the support bracket, or add the characteristics of the sectional profiles on the outlet section and the inlet section in the mass production process, so as to realize the multiple applications of the fan housing.
While the disclosure has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the disclosure needs not be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
