Abstract

A water blower has a blowing section and a control section. The blowing section has an intake member, a fan, a main tube and an outlet member. The intake member has an intake fan and an intake base, the intake fan has a plurality of intake fan blades, the intake fan blades are surrounding by a housing and a plurality of intaking spaces. The housing is secured onto the intake base; the fan has a vortex fan, a fan base and a motor, the fan base has a connecting base at its center, the motor and the vortex fan are respectively mounted at a front and a rear of the fan base, the motor has an axial shaft passing through the connecting base and connected to the vortex fan. The vortex fan has a plurality of vortex fan blades, and a plurality guiding blades.

What is claimed is: 
     
         1 . A water blower comprising a blowing section and a control section, wherein
 the blowing section has an intake member, a fan, a main tube and an outlet member; the control section has a control board for controlling the fan, the main tube is assembled with the control section, the fan is secured in the main tube, and the outlet member and the intake member are respectively connected to a front section and a rear section of the main tube; the intake member has an intake fan and an intake base, the intake fan has a plurality of intake fan blades, the intake fan blades are surrounding by a housing and a plurality of intaking spaces are formed between the intake fan blades; the housing is secured onto the intake base; the fan has a vortex fan, a fan base and a motor, the fan base has a connecting base at its center, the motor and the vortex fan are respectively mounted at a front and a rear of the fan base, the motor has an axial shaft at an end passing through the connecting base and connected to the vortex fan to drive the vortex fan, the vortex fan has a plurality of vortex fan blades, and a plurality guiding blades are mounted between the fan base and the connecting base; the outlet member has an outlet base and an outlet end, the outlet base has a plurality of engaging ribs assembled with the outlet end and a plurality of enhancing outlet are formed between the engaging ribs, and the outlet end has a plurality of through apertures.   
     
     
         2 . The water blower as claimed in  claim 1 , wherein the control board has a cooling fin. 
     
     
         3 . The water blower as claimed in  claim 1 , wherein the motor is an outer rotor motor, and one end of the motor has a conical surface with at least one cooling hole. 
     
     
         4 . The water blower as claimed in  claim 1 , wherein the guiding blade has a first side and a second side, a first angle between 10°-11.5° is formed between the first side and an axial direction of the fan base, a second angle between 12.5°0-13.5° is formed between the second side and an axial direction of the fan base, a difference between the first angle and the second angle causing the guiding blades to be curved and inclined between the fan base and the connecting base. 
     
     
         5 . The water blower as claimed in  claim 1 , wherein a bottom side of the control section has a screen, and the screen has a power indication region and a mode indication region for displaying a current speed of the motor. 
     
     
         6 . The water blower as claimed in  claim 5 , wherein the screen further has a time indicating region for displaying a countdown time, and the control board controls the motor to stop after a predetermined number of seconds to avoid overheating or damage. 
     
     
         7 . The water blower as claimed in  claim 6 , wherein when the motor operates at a highest speed, and the control board is timed to stop the motor after 12 seconds.
