Water Blower

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

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.

An objective of present invention is to provide a water blower, which is capable of improving the above-mention problems.

In order to achieve the above-mentioned objective, a water blower has 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.

Other objects, advantages, and novel features of invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

First, please refer to. A water blower comprises a blowing sectionand a control section. The blowing sectionhas an intake member, a fan, a main tubeand an outlet member. The control sectionhas a control boardfor controlling the fan, the main tubeis assembled with the control section, the fanis secured in the main tube, and an outlet memberand an intake memberare respectively connected to a front section and a rear section of the main tube. The intake memberhas a intake fanand an intake base, the intake fanhas a plurality of intake fan bladessurrounding by a housingand a plurality of intaking spacesare formed between the intake fan blades. The housingis secured onto the intake base, and air is guided by the intake baseto pass from a bottom of the intake faninto the intaking space. The fanhas a vortex fan, a fan baseand a motor. The fan basehas a connecting baseat its center, the motorand the vortex fanare respectively mounted at a front and a rear of the fan base. The motorhas an axial shaftat an end passing through the connecting baseand connected to the vortex fanto drive the vortex fan. The vortex fanhas a plurality of vortex fan bladesand a plurality guiding bladesare mounted between the fan baseand the connecting base. The outlet memberhas an outlet baseand an outlet end, the outlet basea plurality of engaging ribsassembled with the outlet endand a plurality of enhancing outletare formed between the engaging ribs, and the outlet endhas a plurality of through apertures.

As shown in, when the motordrives the vortex fanto rotate, air is blown forward from the bottom surface of the intake fanthrough the intaking space, the intake fan bladesand the vortex fanto generate a vortex, as shown in, since the intake fan bladesand the guiding bladesare all inclined, the air before and after the vortex fanforms vortices, and the same airflow intensity can be achieved by reducing the rotation of the motor. Furthermore, because the air can be concentrated from the bottom surface of the intake fanthrough the intaking spaceso more air can pass through the vortex fan bladeswhich makes the air flow stronger. As shown in, when the air is blown out through the outlet member, its negative pressure guides the surrounding air to be blown out together through the enhancing outletand the through apertures, thereby increasing the amount of air and better efficiency.

Moreover, as shown inand, the control boardhas a cooling fin.

In addition, as shown inand, the motoris an outer rotor motor, and one end of the motorhas a conical surfacewith at least one cooling hole.

As shown inand, in actual operation, when the blowing sectionis in operation, the air blows through the heat sinkto dissipate heat from the control boardat the same time, and the conical surfaceof the motorcan reduce the disturbance to the air flow. In addition, since the cooling holeis disposed on the conical surface, some air can flow into the heat dissipation holesto help the motordissipate heat while reducing air disturbance, thereby achieving better heat dissipation efficiency.

As shown inand, the guiding bladehas a first sideand a second side, a first angle A between 10°-11.5° is formed between the first sideand an axial direction of the fan base, a second angle B between 12.5°-13.5° is formed between the second sideand an axial direction of the fan base, a difference between the first angle A and the second angle B cause the guiding bladesto be curved and inclined between the fan baseand the connecting base.

As shown inand, a bottom side of the control sectionhas a screen, and the screenhas a power indication regionand a mode indication regionfor displaying a current speed of the motor.

As shown in, the screenfurther has a time indicating regionfor displaying a countdown time, and the control boardcontrols the motorto stop after a predetermined number of seconds to avoid overheating or damage.

Additionally, when the motoroperates at a highest speed, and the control boardis timed to stop the motorafter 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.
