Abstract
The invention relates to a wave-shaped fan blade of an ordinary fan. The wave-shaped fan blade consists of a fan blade, blade convex parts and blade concave parts, wherein the blade convex parts and the blade concave parts are arranged in the fan blade, and the radial blade convex parts and blade concave parts are distributed on the fan blade. After the fan manufactured according to the scheme provided by the invention, the problem that wind blown by the original approximate plane blades causes strong impact feeling on people, and when the uneven wave-shaped fan blade rotates, softer wind is generated, so that people feel more comfortable.
Description
Technical field
The present invention relates to a kind of flabellum of common rotary vane fan, is a kind of waveform electric fan be used on common rotary vane fan.
Background technique
Fan is a kind of product that people are familiar with very much, can be divided into desk fan, stand fan, wall fan, ceiling fan, ventilation fan, rotary blade fan etc., be divided into have leaf electric fan and fan without blades by blade by structure and use feature.Common have blade fan to be all use motor to drive flabellum rotary work, but conventional fan uses blade cuts air to promote air-flow, can produce violent impact, allow people feel very uncomfortable when such air-flow blows to human body.
Summary of the invention
Existingly commonly blade fan is had to use blade cuts air push air-flow to overcome, such air-flow can produce violent impact when blowing to human body, people is allowed to feel very uncomfortable shortcoming, the present invention proposes a kind of waveform flabellum of conventional fan, the wind using this flabellum to blow out is comparatively soft comfortable, allows people feel more natural.
The technical solution adopted for the present invention to solve the technical problems is:
The waveform flabellum of a kind of conventional fan of the present invention, be made up of the blade protuberance in fan blade and fan blade, blade recess, in fan blade, be distributed with radiating blades protuberance and blade recess, just as wave, when this rough blade rotation, the wind of blowout no longer as original almost plane blade what kind of give people violent impact, make people feel comfortable nature.
Accompanying drawing explanation
Below in conjunction with accompanying drawing to brief description of the present invention.
Fig. 1 is the waveform blade structure schematic diagram of a kind of conventional fan of the present invention.
1. fan blade in figure, 2. blade protuberance, 3. blade recess.
Embodiment
In the embodiment in figure 1, we to implement a kind of waveform flabellum of conventional fan, the present invention is further described:
In FIG, electric fan is conventional fan flabellum, be divided into three leaves, electric fan 1 is with plastics or metal manufacture, on the face of electric fan 1, be distributed with many blade protuberances 2 and blade recess 3, make blade no longer smooth, concavo-convex to surrounding radioactivity in center, just as wave, recess and protuberance quantity can design according to specific needs, also can suitably be out of shape.
When concrete production, if plastic blade, mould can be used to produce in batches, if metallic material makes blade, the compacting of mould batch also can be used, after being installed by this flabellum, when fan blade rotates, uneven due to flabellum, its wind is full of variety, and makes people feel softer, nature.
Claims (1)
1. the waveform flabellum of a conventional fan, be made up of the blade protuberance (2) in fan blade (1) and fan blade, blade recess (3), it is characterized in that: in fan blade (1), be distributed with radiating blades protuberance (2) and blade recess (3).
