Therefore, the integrated structure not only can ensure structure and performance stability of the baffle 117 and the top cover 115, but also is convenient to be formed and easy to be manufactured. Further, redundant assembly parts and connection steps can be removed, which greatly improves assembly efficiency of the baffle 117 and the top cover 115 and ensures reliability of a connection between the baffle 117 and the top cover 115. Furthermore, the integrated structure is high in overall strength and stability, more convenient to be assembled, and long in service life.
