CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is a National Stage of International Application No. PCT/CN2011/081661 filed Nov. 2, 2011, claiming priority based on Chinese Patent Application No. 201110291841.9 filed Sep. 30, 2011, the contents of all of which are incorporated herein by reference in their entirety.

FIELD

The following description relates to a fan, and more particularly, to a bladeless fan.

DESCRIPTION OF RELATED ART

A general fan is composed of a fan frame, a driving motor installed in the fan frame and rotatable blades connected the driving motor. Generally, a blowhole in front of the blades is covered by a protective cover for safety. As the protective cover of the fan has a plurality of openings, it is possible that children's fingers may be injured. In addition, since the general fan creates airflow using blades, a strong air flow is generated with inconsistent intensity so that the user may feel uncomfortable. The blades have to be detached, re-assembled and tested for cleaning, and the whole process causes huge inconvenience to the user.
In order to solve the above problem, a blade-concealed fan has been designed. The blade-concealed fan includes a body and an blower having a blowhole in the front-end through which airflow communicates, the body includes a body case having installed therein blades and a motor, the motor drives the blades to rotate, and an air suction hole is formed in the body case. The above fan does not need outwardly-exposed blades and its function is only to push airflow to circulate so that it fails to meet the recent demand for a multifunctional device and leads to a less noticeable practicality. In addition, control buttons of the conventional electric fan of the related art are generally installed in the body case so that the control buttons are not rotated in response to the rotation of the body case. Hence, it is inconvenient to manipulate the level of airflow intensity and to turn on/off the fan.

The blower 1 may be formed in other shapes as long as a blowhole is installed between the blower internal case 11 and the blower external case 12 so as to blow out airflow. Since the airflow is forcibly blown out from the blowhole of the blower 1 with the volume of the blown-out airflow increased up to 15 times and the speed of up to 35 km, the blown out airflow is softer than that of a conventional fan and a user may feel comfortable.
As shown in FIGS. 1 and 3, to be specific, the air suction hole 3 is formed on the sidewall of the rotation case 211 in a circumference direction, the blast area of the air suction hole 3 gradually decreases from the external to the internal, and the largest blast area of the air suction hole 3 is 2 to 5 times greater in size than the narrowest blast area. The cross-sectional area of the air suction hole 3 is in a ring, elliptical or rectangle shape, the interval between two adjacent air suction holes 3 is from 1 mm to 2 mm, the air suction hole 3 absorbs a greater volume of air, has a notable effect in air suction and ensures that airflow smoothly goes through the air suction hole 3 into the rotating body 21 so that noise may be effectively reduced, a consistent volume of air is absorbed and high practicality are achieved.
As shown in FIG. 2, the rotating body 21 further includes a motor base 214 configured to fix the motor 213, a motor auxiliary base 215 configured to fix the motor base 214, a motor support 216, a motor cover 217 configured to cover the top of the motor 213 and a bracket 218 installed on the top of the motor cover 217, the turbine 212 is installed between the motor auxiliary case 215 and the motor support 216, and the motor support 216 is detachably installed on the inner sidewall of the rotation case 211.

Among them, a plurality of blades with the same shape and structure are installed inside of the turbine 212, a plurality of blades are arranged in a spiral fashion, the same interval is formed between two adjacent blades, an air flux boosted using the pressure intensifying principle of the turbine 212 goes through the blower 1 so that the volume of the airflow in the blower 1 increases, resulting in a greater volume of the blown-out air and a highly efficient blow effect.

As shown in FIGS. 2, 4 and 5, the synchronous driving mechanism 222 includes a synchronous rotatable plate 223 and a synchronous bracket 224, the central parts of the synchronous rotatable plate 223 and the synchronous bracket 224 are connected to each other through a rotation shaft 225, a synchronous motor 226 is installed on the synchronous rotatable plate 223, an eccentric shaft sheet 227 is installed on the synchronous bracket 224, an eccentric shaft 228 is installed on the eccentric shaft sheet 227, and a rotation shaft of the synchronous motor 226 is connected to a transmission metal sheet 229 through the eccentric shaft 228.
The synchronous motor 226 leads the rotation shaft 225 via the transmission metal sheet 229 to rotate, thereby making the synchronous bracket 224 rotate around the rotation shaft 225 and, in turn, leading the rotating body 21 and the blower 1 to horizontally rotate. Specifically, the second eccentric shaft sheet 227 is connected to the rotation shaft 225 of the synchronous motor 226, and the second eccentric shaft 228 of the second eccentric shaft sheet 227 is connected to the transmission metal sheet 229, thereby helping the synchronous bracket 224 to rotate back and forth against the synchronous rotation plate 223 with a simple structure and high practicality.

Resonance is generated through a vibration circuit and a unique vibration frequency of a piezoelectric ceramic so that the size of the liquid droplet atomized by the ultrasonic atomizer 54 which is in direct contact with the piezoelectric ceramic is between 1 μm and 3 μm. The liquid droplets atomized using the air-blowing mechanism 53 are evenly diffused into the air using an atomizing mechanism, humidifies the air and generates an abundant amount of anion so that the atmosphere becomes cleaner and better for health.
In summer, installation of the atomizing device 5 reduces indoor temperature so that indoor environments become cooler and air-conditioners are used less, resulting in energy saving and less electricity consumption. In winter, if the indoor environments are too dry, it is possible to control the touch screen controlling device 4 to operate only the atomizing device 5 for humidification, leading to a more pleasant atmosphere and meeting the demand for a multi-functional fan.
As shown in FIG. 10, the water tank body includes a water tank case 510, a water tank lower case 511 configured to seal the water tank case 510 and a bottom box 512 installed below the water tank lower case 511, a water tank fixing part 513 is installed in the water tank lower case 511, the ultrasonic atomizer 52 is installed on the top surface of the bottom box 512, the second PCB 55 is installed on the top surface of the bottom box 512, the air-blowing mechanism 53 includes a blow guide funnel 531 connected to the atomizing mechanism and a fan 532 connected to the blow guide funnel, the blow guide funnel 531 is fixed on the top surface of the bottom box 512, the fan 532 is fixed on the bottom surface of the bottom box 512, the atomizing mechanism includes a blowing frame 541 installed on the top of the bottom box 512, the first boss 542, an atomization tank 543 and an atomizing nozzle 544 connected to the atomization tank 543 and an atomizing ring 545 installed on the top of the atomizing nozzle 544, the first boss 542 and the atomization tank 543 are installed on the blowing frame 541 and connected to each other, the atomization tank 543 is installed on the top of the ultrasonic atomizer 52 while facing forward, the blowing frame 541 is connected to the water tank lower case 511 through the first boss 542, the second boss 514 of the water tank lower case 511 is sleeve-connected to the top of the first boss 542, and the blowing frame 541 and the water tank case 510 are coupled into one set.
Liquid such as water may be filled in the water tank case 510 by opening the water tank fixing part 513, and the water tank fixing part 513 may be used not only for filling but also emptying the water tank case 510 so that a simple structure without a water intake port and an easy process with reduced production costs may be realized. Since the first boss 542 is configured to cover the top of the blow guide funnel 531 and the second boss 514 is sleeve-connected to the top of the first boss 542, the blowing frame 541 is in a good position to from a rabbit joint with the water tank case 510, the connection between the blowing frame 541 and the water tank body is fairly stable, the blowing frame 541 needs smaller space and a reasonable design with simple assembly and disassembly methods is realized.

Among them, the atomizing ring 545 includes an atomization front case and an atomization back case, an atomization area is formed between the atomization front case and the atomization back case, and an atomizing direction in the atomization area is the same as the air-blowing direction of the blowhole of the blower 1 so that consistent atomization is ensured with a significant atomization effect.
As shown in FIG. 10, a sensor-embedded supporting foot 9 is installed inside of the bottom box 512 and a magnetic pole 10 is installed on the top surface of the bottom box 512. Since the sensor-embedded supporting foot 9 floats on the top surface of liquid, the sensor-embedded supporting foot 9 goes down if the amount of the liquid on the bottom box 512 is reduced, and, if there is no liquid, raises an alarm for water shortage while automatically stopping the atomization using the second PCB 55 at the same time so that it prevents an operation in dry environments and boasts great in-use stability.

Desirably, two magnetic blocks 5161 are necessary, and each of the two magnetic blocks 5161 needs to be disposed above and below the arc-shaped protruding block 519 of the back case 516 to correspond to each other, thereby making it easy to open and close the front door 517 and to use the front door 517. A transparent front door window 518 is formed in the front door 517 and a scale is coupled to the front door window 518 so that it is easy to check the amount of water in the water tank case 510 and it is possible to avoid an operation in dry environments due to water shortage, leading to great in-use safety.
Among them, installation of the bottom plate 515 makes the atomizing device 5 to stand stably and, specifically, a bobbin spool is installed on a bottom surface of the bottom plate 515 so as to make it convenient to put electrical cords under the bottom plate 515, thereby leading to space saving, easy storage and simple manipulating.
