Abstract
The utility model relates to a rotatable type bladeless fan. The rotatable type bladeless fan comprises an annular nozzle, a foundation support, a rotating base seat and a fixing chassis, wherein the annular nozzle, the foundation support, the rotating base seat and the fixing chassis are installed in sequence from top to bottom. The annular nozzle, the foundation support and the rotating base seat are installed into a whole, the rotating base seat and the fixing chassis are installed in a concentric mode and can rotate relatively, the rotating base seat is fixedly provided with a bidirectional synchronous motor, a round wheel gear is installed at an output end of the bidirectional synchronous motor, and the fixing chassis is fixedly provided with a sector gear which is meshed with the round wheel gear. The rotatable type bladeless fan achieves rotation of the bladeless fan by adopting a gear transmission mechanism, and thereby the rotatable type bladeless fan is not only simple and compact in structure, low in failure rate and convenient to assemble, but also high in work efficiency. The rotatable type bladeless fan can save the motor energy and reduce the cost and the noise.
Description
Technical field:
The utility model relates to fan art, and particularly a kind of rotary type is without blade fan.
Background technique:
Existing realize rotating by the mechanical lever transmission device without blade fan, because motor-driven is on same axis, so surface friction drag is large, noise is large, and very high to motor torque, power requirements, working efficiency is subject to certain limitation.Because power line also is to swing back and forth with leverage, causes the power line fatiguability, and is easily broken.Its complex structure, assembly process is loaded down with trivial details, and structure is not compact, and rate of fault is high, wastes a large amount of human and material resources.
The model utility content:
Goal of the invention of the present utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of motor energy of saving is provided, and improves electric wire working life, and simple in structure, compact, easy to assembly, and the rotary type of failure rate is low is without blade fan.
Goal of the invention of the present utility model is achieved through the following technical solutions:
A kind of rotary type is without blade fan, comprise the ring nozzle, pedestal, rotating base and the fixed underpan that set gradually from top to bottom, described ring nozzle, pedestal and rotating base are installed as one, described rotating base also can relatively rotate with the coaxial setting of fixed underpan, be fixedly installed a two-way synchronous machine on the described rotating base, the output terminal of described bi-directional synchronization motor is equipped with a Knucle-gear, is fixedly installed a tooth sector that is meshed with Knucle-gear on the described fixed underpan.
On the described fixed underpan along circumferentially being symmetrically arranged with some arc-shaped guide rail grooves, the guide rod that is provided with respective numbers on the described rotating base and is rotatably assorted with each arc-shaped guide rail groove respectively.
The axle center of described rotating base and fixed underpan is provided with the axle center hole that passes through for the power supply source line.
The beneficial effects of the utility model are: at first, the employing gear drive is realized the rotation without blade fan, and is not only simple and compact for structure, and failure rate is low is easy to assembly, and high working efficiency, can save the motor energy, reduces cost, also can reduce noise.Secondly, power line directly passes from the center hole of rotating base and fixed underpan, has solved fatiguability and the easily broken phenomenon of power line, the working life of having improved power line.
Description of drawings:
Fig. 1 is that the utility model rotary type is without the exploded perspective view of blade fan.
Fig. 2 is the package assembly schematic diagram of rotating base and fixed underpan in the utility model.
Embodiment:
As depicted in figs. 1 and 2, the described a kind of rotary type of the utility model embodiment comprises the ring nozzle 1, pedestal 2, rotating base 3 and the fixed underpan 4 that set gradually from top to bottom without blade fan, and ring nozzle 1, pedestal 2 are installed as one with rotating base 3.Rotating base 3 also can relatively rotate with fixed underpan 4 coaxial settings, be fixedly installed a two-way synchronous machine 5 on the rotating base 3, the output terminal of bi-directional synchronization motor 5 is equipped with a Knucle-gear 6, is fixedly installed a tooth sector 7 that is meshed with Knucle-gear 6 on the fixed underpan 4.
On the fixed underpan 4 along circumferentially being symmetrically arranged with some arc-shaped guide rail grooves, the guide rod that is provided with respective numbers on the rotating base 3 and is rotatably assorted with each arc-shaped guide rail groove respectively.The axle center of rotating base 3 and fixed underpan 4 is provided with the axle center hole 31,41 that passes through for the power supply source line.
This rotary type without the Principle of Rotating of blade fan is: start bi-directional synchronization motor 5, Knucle-gear 6 is rotated to the other end along external tooth one end of tooth sector 7, and drive bi-directional synchronization motor 5, rotating base 3, pedestal 2 and ring nozzle 1 rotate together, when Knucle-gear 6 turns to the outer tooth ends of tooth sector 7, bi-directional synchronization motor 5 is auto-reverse, Knucle-gear 6 is rotated along the external tooth of tooth sector 7 in the other direction, and drive bi-directional synchronization motor 5, rotating base 3, pedestal 2 and ring nozzle 1 be counter-rotation together, and so forth circulation realizes rotating back and forth about rotary type is without blade fan.In addition, about rotate back and forth in the process, the guide rod on the rotating base 3 comes back rotation along the arc-shaped guide rail groove of fixed underpan 4, plays the effect of guide-localization.
Above-described embodiment is only for illustration of the utility model; and be not limitation of the utility model; the those of ordinary skill in relevant technologies field; in the situation that do not break away from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all technological schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
