WATER BLOWER

Description

BACKGROUND OF THE INVENTION

Field of Invention

The present invention relates to a water blower, and more particularly to a water blower with high efficiency.

Description of the Related Art

A water blower is a tool that can produce a large amount of airflow to blow away water. It can be used to blow away water droplets to avoid water stains. In order to increase the air flow, the conventional water blower is often a high-power machine, and high power also means high energy consumption and the accompanying waste heat. Overheating of the machine not only affects efficiency and may cause danger, but also shortens the use time of the water blower.

If the efficiency of the water blower is high, the amount and force of air blowing can meet the user's needs with less energy consumption. The motor will not need to over-operate, which can reduce energy consumption and increase the life of the water blower, extending the service life of the water blower.

Therefore, it is desirable to provide a water blower to mitigate and/or obviate the aforementioned problems.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

First, please refer to FIGS. 1-8. A water blower comprises a blowing section 10 and a control section 20. The blowing section 10 has an intake member 11, a fan 12, a main tube 13 and an outlet member 14. The control section 20 has a control board 21 for controlling the fan 12, the main tube 13 is assembled with the control section 20, the fan 12 is secured in the main tube 13, and an outlet member 14 and an intake member 11 are respectively connected to a front section and a rear section of the main tube 13. The intake member 11 has a intake fan 111 and an intake base 112, the intake fan 111 has a plurality of intake fan blades 1111 surrounding by a housing 1112 and a plurality of intaking spaces 1113 are formed between the intake fan blades 1111. The housing 1112 is secured onto the intake base 112, and air is guided by the intake base 112 to pass from a bottom of the intake fan 111 into the intaking space 1113. The fan 12 has a vortex fan 121, a fan base 122 and a motor 123. The fan base 122 has a connecting base 1221 at its center, the motor 123 and the vortex fan 121 are respectively mounted at a front and a rear of the fan base 122. The motor 123 has an axial shaft 1231 at an end passing through the connecting base 1221 and connected to the vortex fan 12 to drive the vortex fan 121. The vortex fan 121 has a plurality of vortex fan blades 1211 and a plurality guiding blades 1222 are mounted between the fan base 122 and the connecting base 1221. The outlet member 14 has an outlet base 141 and an outlet end 142, the outlet base 141 a plurality of engaging ribs 1411 assembled with the outlet end 142 and a plurality of enhancing outlet 1412 are formed between the engaging ribs 1411, and the outlet end 142 has a plurality of through apertures 1421.

As shown in FIG. 9, when the motor 123 drives the vortex fan 121 to rotate, air is blown forward from the bottom surface of the intake fan 111 through the intaking space 1113, the intake fan blades 1111 and the vortex fan 121 to generate a vortex, as shown in FIGS. 3 and 4, since the intake fan blades 1111 and the guiding blades 1222 are all inclined, the air before and after the vortex fan 121 forms vortices, and the same airflow intensity can be achieved by reducing the rotation of the motor 123. Furthermore, because the air can be concentrated from the bottom surface of the intake fan 111 through the intaking space 1113 so more air can pass through the vortex fan blades 1211 which makes the air flow stronger. As shown in FIG. 10, when the air is blown out through the outlet member 14, its negative pressure guides the surrounding air to be blown out together through the enhancing outlet 1412 and the through apertures 1421, thereby increasing the amount of air and better efficiency.

Moreover, as shown in FIG. 2 and FIG. 8, the control board 21 has a cooling fin 22.

In addition, as shown in FIG. 2 and FIG. 8, the motor 123 is an outer rotor motor, and one end of the motor 123 has a conical surface 1232 with at least one cooling hole 1233.

As shown in FIG. 8 and FIG. 9, in actual operation, when the blowing section 10 is in operation, the air blows through the heat sink 22 to dissipate heat from the control board 21 at the same time, and the conical surface 1232 of the motor 123 can reduce the disturbance to the air flow. In addition, since the cooling hole 1233 is disposed on the conical surface 1232, some air can flow into the heat dissipation holes 1233 to help the motor 123 dissipate heat while reducing air disturbance, thereby achieving better heat dissipation efficiency.

As shown in FIG. 4 and FIG. 5, the guiding blade 1222 has a first side 1223 and a second side 1224, a first angle A between 10°-11.5° is formed between the first side 1223 and an axial direction of the fan base 122, a second angle B between 12.5°-13.5° is formed between the second side 1224 and an axial direction of the fan base 122, a difference between the first angle A and the second angle B cause the guiding blades 1222 to be curved and inclined between the fan base 122 and the connecting base 1221.

As shown in FIG. 11 and FIG. 12, a bottom side of the control section 20 has a screen 23, and the screen 23 has a power indication region 231 and a mode indication region 232 for displaying a current speed of the motor 123.

As shown in FIG. 12, the screen 23 further has a time indicating region 223 for displaying a countdown time, and the control board 21 controls the motor 123 to stop after a predetermined number of seconds to avoid overheating or damage.

Additionally, when the motor 123 operates at a highest speed, and the control board 21 is timed to stop the motor 123 after 12 seconds.

Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of invention as hereinafter claimed.
