Description

An ultrasonic atomization spray cooling electric fan

technical field

The utility model relates to a spray cooling electric fan, in particular to an ultrasonic atomization spray cooling electric fan.

Background technique

The current electric fans are generally driven by the motor to rotate the blades to blow air. When the temperature is high, the air blown out is still hot and has no cool feeling, and may even feel hotter. When there is water vapor in the wind blown by the fan, the effect of cooling will be achieved due to the evaporation of water vapor and direct contact with human skin. The Chinese patent with application number 200720072016.9 discloses a spray fan. The principle is that a water storage box is provided at the base of the fan, and an atomizer is provided in the fan safety net to atomize the water in the water storage box. Blow out water vapor to cool down the temperature. But this patent only involves the position of the water storage box and the position of the atomizer. The Chinese patent No. 200610035372.3 discloses a portable misting fan, which also uses the fan to blow out the water mist from the atomizing device to cool down. This patent mainly emphasizes that the injection port of the liquid storage chamber is set at the lower part of the body facing downward. . The Chinese patent No. 200610108828.4 discloses a portable spray fan, which relates to the specific structure of the fan. Its atomization system uses an air pump to complete the liquid siphon and pushes the atomization through compressed air. The Chinese patent application number 200520113678.7 discloses a spray fan, which relates to a spray fan with a water spray head and an angle-adjustable water spray plate installed at the front side of the air outlet of the fan. The water mist is blown away to achieve the purpose of cooling. The Chinese patent application number 200920122153.8 discloses a spray fan with a spray ring on the fan head and several nozzles on the spray ring. It is sprayed from the nozzle to form water mist, which is blown out by the fan to achieve the cooling effect.

The spray fans disclosed above all spray in front of the fan blades, and the water mist is blown out by the rotation of the fan blades. There are two ways to form water mist: pumps and compressed air, but there are deficiencies in such structures and atomization methods. One is The mist droplets are too large, and the diffusion distance is limited when blowing out. It is easy to form water droplets on people's clothes or skin, and wet the clothes or nearby items. Second, the water mist is formed in front of the fan blades, and the wind blows behind, causing water The mist is not well dispersed. The third is that the water mist is formed by the water pump or the air compressor. The machine consumes a lot of energy and makes a lot of noise, so it is not suitable for home use and quiet places.

Accompanying drawing 2 is the front schematic view of the structure of the ultrasonic atomization type spray cooling type electric fan.

Detailed ways

As shown in Figure 1 and Figure 2, the ultrasonic atomization spray cooling fan of the present invention includes a fan body and an ultrasonic atomization device. The fan body includes a fan blade 1 and a windshield 2 located outside the fan blade; the windshield 2 can adjust its inclination within a certain angle range, and its lower part is provided with a water droplet return port 21; the ultrasonic atomization device includes a water tank 4, an ultrasonic Atomizing sheet 5, water-absorbing rod 6 and casing 7; atomizing sheet 5 is made of metal microporous sheet and piezoelectric ceramics tightly bonded, metal microporous sheet has 1-5000 micropores, and the diameter of the outlet hole is 3 Between -15μm.

The lower part of the fan body is connected to the fan base 3, and a circuit board, a wind speed adjustment knob 31, a power switch 32, a power indicator light 33, and a power socket 34 are installed in the fan base 3. An opening 35 is arranged on the position, and this opening communicates with the water tank 4 .

At the same time, the fan base 3 also doubles as the top cover of the water tank 4; the casing 7 is located in the water tank 4, and its top is installed on the fan base; The foil 5 is fixed on the top of the casing 7 by a fixing member, and is located below the spray port 8 on the fan base; the spray port 8 is located behind the junction of the fan body and the fan base.

When the fan is working, the water in the water tank 4 is guided to the bottom of the ultrasonic atomizing sheet 5 by the water-absorbing rod 6, and enters the micropores through capillary action, and is ejected under the ultrasonic vibration, and the water in hundreds of thousands of micropores is released at the same time. Spray vertically upwards from the mist outlet 8 located behind the electric fan to form 5-20 μm mist droplets. Attracted by the kicking wind formed by the high-speed rotation of the fan, the fog droplets are accelerated and blown forward with the wind formed by the fan.

When the fan blade 1 rotates at high speed, it will form large water droplets due to cutting the water mist. The water droplets will be thrown on the inner side of the windshield 2 under the centrifugal force, and flow along the inner wall of the windshield 2 to the bottom of the windshield, and pass through the water drop return port 21 and the opening 34 Flow back in the water tank 4.

The ultrasonic atomization spray cooling fan of the utility model is powered by an external 12V power adapter, and the power is below 5W; the wind cover 2 and the water tank 4 are made of plastic or metal; the water tank 4 and the base 3 can be designed into various shapes according to the needs. shape.

The ultrasonic atomization spray cooling fan provided by the utility model, because there is water vapor in the wind, the water vapor instantly evaporates and absorbs heat, so that the blown wind is cooler than the wind without water vapor, achieving an obvious cooling effect; using ultrasonic micropores Atomization technology sprays, the formed mist droplets are fine and strong, avoiding the disadvantages of wetting clothes due to large mist droplets, and at the same time have the characteristics of low energy consumption and low noise; the atomization device is installed behind the fan blades, relying on the fan The suction force after the rotation sprays the water mist, and the inclination of the windshield 2 can be adjusted to make the mist dispersibility better.
