  • mist-spraying fan which provides humidity in addition to ventilating and cooling effects.
  • the mist-spraying fan includes: a base 1 , a support 2 mounted on the base 1 , a head assembly 3 mounted on a top of the support, and a control device.
  • the control device is a system of circuit control which controls the entire electrical operation of the fan and the mist-spraying device.
  • the head assembly 3 includes a motor 31 , fan blades 32 driven by the motor, and a mantle 33 housing the fan blades. All of the above mentioned components are well-known structures in the art.
  • the mist-spraying fan includes: an atomizing device 4 disposed in the base 1 , a mist-spraying pipe 5 disposed adjacent to the fan blades 32 and in this embodiment the mist-spraying pipe is disposed on a front side of the fan blades, the mist-spraying is connected to the atomizing device via an atomizing passage 6 .
  • the atomizing device is an ultrasonic vibrating atomizer which generates a cold water vapor (mist) from water, using a process known as “cold boiling.”
  • the main purpose of the atomizing device is to generate mist; therefore, the atomizing device can be any other atomizing device with a different structure, as long as it achieves its purpose.
  • the mist-spraying pipe is disposed on the front side of the fan blades so that the mist ejected from the mist-spraying pipe is dispersed by rotation of the fan blades. As can be seen, in this embodiment no mist passes through the motor so that the mist does not cause corrosion and damage to the motor.
  • the atomizing passage 6 is located in a channel inside the support 2 whose top connects to the mist-spraying pipe.
  • the support 2 may be manufactured as a hollow structure, and the hollow chamber of the support 2 and the mist-spraying pipe are connected so as to form the atomizing passage.
  • a plurality of mist-spraying holes 51 is disposed on the mist-spraying pipe; the mist-spraying holes are through holes and face to the fan blades.
  • the fan blades produce wind, and while the wind passes through the mist-spraying holes, the mist inside the mist-spraying holes is dispersed by the wind, while simultaneously forming a vacuum in the upper portion of the mist-spraying pipe so that the mist located in the lower part is sucked up and ejected.
  • one of the mist-spraying holes has a diameter larger than those of the other mist-spraying holes whose positions on the mist-spraying pipe are below that of the one mist-spraying hole on the mist-spraying pipe, that is, the higher the position of a mist-spraying hole on the mist-spraying pipe is, the larger the diameter of the mist-spraying hole.
  • the amount of the mist ejected from the holes varies with the change in height of the holes.
  • the mist-spraying hole at the lowest position ejects the greatest amount of mist, whereas the mist-spraying hole at the highest position ejects the least amount of mist. Because of this, one of the mist-spraying holes has a diameter larger than those of the other mist-spraying holes whose positions on the mist-spraying pipe are below that of the one mist-spraying hole on the mist-spraying pipe, e.g.
  • the diameter of the mist-spraying hole at the highest position on the mist-spraying pipe is the largest, and the lower the position of a mist-spraying hole on the mist-spraying pipe is, the smaller the diameter of the mist-spraying is, thereby the amount of the mist ejected in the lowest position can be limited, and the amount of the mist ejected in the highest position can be increased, as a result that the ejected amount of the mist between top and bottom are basically equal.
  • the effect of atomizing is also improved by the equal ejection of the mist to the fan blades 32 .
  • each mist-spraying hole becomes larger gradually from front to rear such that each mist-spraying hole is formed as a cone-shaped hole, e.g. an end of the mist-spraying hole which is close to the fan blades is large, and the other end of the mist-spraying hole from which the mist is ejected is small, with such structure, the mist can re-atomize again and the effect of atomizing is improved.
  • the mist-spraying pipe is in the form of an annular structure and the outside diameter is smaller than the rotating diameter of the fan blades, and the distance between each mist-spraying hole and a rotating center of the fan blades is 0.3-0.7 times as large as the rotating radius of the fan blades. For instance, the distance between the mist-spraying hole and a rotation center of the fan blades is 0.5 times as large as the rotation radius of the fan blades in this embodiment.
  • the above-mentioned structure produces more efficient suction of the mist inside the mist-spraying pipe 5 .
  • a water chamber 11 is disposed inside the base 1 , and the atomizing device 4 is mounted in the water chamber 11 .
  • the water chamber 11 contains water so that the atomizing device 4 conveniently atomizes water. It is advantageous for using the base 1 as a water container: firstly, the structure of the present invention becomes more compact by saving space; secondly, because the base 1 contains water, the fan can stand steadier and hardly fall down.
  • a water inlet 111 is disposed on the top of the water chamber 11 , and a water tank 7 is installed on the place of the water inlet 11 .
  • the tank 7 can contain more water such that the period of the continual atomizing is increased.
  • a hollow thermal insulation layer 75 is provided inside the tank 7 , therefore the temperature of water inside the tank can be ensured. If cold mist is needed, the hollow thermal insulation layer can maintain the temperature of cold water contained in the water tank, therefore cold mist can be provided as needed.
  • the present invention ensures the stability of the internal water temperature and makes the temperature of the ejected mist steady, thus it is advantageous for adjusting the environmental temperature.
  • a water groove 112 is provided at the water inlet 111 , a water inlet pipe 113 is disposed in the water groove 112 , the water inlet 111 is disposed on the water inlet pipe 113 , an outlet of the water tank is provided with a sealing cover plate 72 , with a pushing rod 73 which drives the sealing cover plate 72 move and with a spring 74 which fits with the pushing rod 73 by the water inlet pipe so as to drive the sealing cover plate to move, and with a spring fitting with the pushing rod.
  • the water inlet pipe 113 can push the pushing rod 73 , then the pushing rob 73 pushes the sealing cover plate 72 to move toward to the water tank, thus the outlet of water is opened, and the water of the water tank flows into the water chamber 11 via the water inlet 111 of the water inlet pipe 113 .
  • the water groove 112 stores water until the level of water reach a position of the water outlet and then water no longer flows out from the water tank.
  • the water tank starts providing water again, thus there is always enough water in the water chamber.
  • the existence of the sealing cover plate 72 prevents water from flowing out from the water outlet 71 as the water tank is being lifted.
  • the present invention comprises a base 1 , a support 2 mounted on the base 1 , a head assembly 3 mounted on a top of the support, and a control device.
  • the control device is a system of circuit control which controls the entire electrical operation of the fan.
  • the head assembly 3 includes a motor 31 , fan blades 32 driven by the motor and a mantle 33 .
  • An atomizing device 4 is disposed in the base 1 , a mist-spraying pipe 5 is disposed between the fan blades 32 and the motor 31 .
  • the mist-spraying device is connected to the atomizing device via an atomizing passage 6 .
  • the atomizing device is an ultrasonic vibrating atomizer which can produce mist from water.
  • a main purpose of the atomizing device is to generate mist, therefore, the atomizing device can be any other atomizing device and can have a different structure.
  • the mist-spraying pipe is disposed on the back side of the fan blades, thus the mist generated by the atomizing device is sucked from the mist-spraying pipe via atomizing passage 6 , due to vacuum formed at the rear of the fan blades while the fan blades are rotating. Because the mist-spraying pipe 5 is disposed between the fan blades 32 and the motor 31 , there is no mist passing through the motor so that the mist will not cause any corrosion and damage to the motor.
  • a plurality of mist-spraying holes 51 are disposed on the mist-spraying pipe, the openings of the mist-spraying holes face to the fan blades.
  • the mist-spraying holes are adjacent to the fan blades so that the mist is easily ejected.
  • the other structures of this embodiment are identical to the structures of the first embodiment.
  • mist-delivering blades 61 are provided in the base and driven by a mist-delivering motor 62 .
  • the mist-delivering blades 61 blow the mist generated by the atomizing device 4 into the atomizing passage 6 , when the suction force of the fan blades 32 is small, the mist can also be ejected from the mist-spraying pipe 5 .
  • the ejection of the mist is not limited by the intensity of wind of the fan blades, e.g. the mist ejection of the electric fan is not affected by the speed of fan blades.
  • the other structures of this embodiment are identical with the structure of the above mentioned embodiments.
