Description of the invention: [Technical field to which the invention pertains] The present invention relates to a fan frame structure, and more particularly to a fan frame structure applied to an axial flow type cooling fan. . j [Prior Art] In order to avoid contamination by dust in the atmosphere, general electronic products will place electronic components in a relatively closed casing. However, since an electronic component such as a central processing unit (CPU) or a circuit board generates a lot of heat during operation, if the electronic component continues to be at a high temperature, it will easily cause component loss and shorten its life. Therefore, in order to avoid malfunction of the electronic components, a cooling fan is generally disposed therein to dissipate the internal high temperature to the outside. See FIGS. 1A and 1B, which is a conventional cooling fan 1 used in general. The frame u and a blade 12 are formed. When the fan is running, the fan can be driven to rotate by the motor to generate gas: a blowing element that generates heat to achieve heat dissipation. The fan ^1 includes an air inlet and an air outlet, and the air inlet and the air outlet are connected by a central cylindrical flow passage 111, and the flow passage can freely flow into and out of the airflow generated by the blade 12. In the traditional fan, the square fan frame is used. In order to increase the air intake and the heat dissipation effect, the general method is to change the air inlet surface f, but due to the size of the square frame, r but the increased air volume. Still, the bran is not in the right picture, and the η~ can't be the best with the flow curve. It also wastes the space and material of the fan frame. β 1325104 is the reason, this creation is based on the conventional technology. The lack of it is a careful experiment and research and a perseverance spirit, and finally created the "fan frame structure of the cooling fan". The following is a brief description of the case. SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a fan and a fan casing having a water discharge structure. In order to achieve the above object, in accordance with the present invention, a fan includes a fan housing, a motor, and a blade, and the fan housing further includes a first pressure zone, a second pressure zone, and a guide. The pressure of the first pressure zone is higher than the pressure of the second pressure zone; the guiding portion has at least two ends, one end is located in the first pressure zone, and the other end is located in the second pressure zone, and the motor is disposed in the fan casing. The blades are connected to the motor. The above and other objects, features, and advantages of the present invention will become more apparent and understood. It is to provide a fan frame structure of a cooling fan, which is to change the square outer hinge to a rectangular shape.
