Abstract
The invention provides a gentle-breeze fan blade of a household fan. The gentle-breeze fan blade is applied to the household fan, and more than three cambered fan blades are evenly distributed on a revolving base. Comb needles are fully arranged on the positive surface of each fan blade. Each comb needle is a metal needle of which the top is sharp. Furthermore, the fan blades are non-conductors. A metal wire is led out from the end portion, in contact with the fan blade, of each metal comb needle, and the metal wire extends to the revolving base. The metal wires led out from all the comb needles are gathered to a metal body on the revolving base, and the metal body is earthed. When the gentle-breeze fan blades work, in the process when the fan blades push air, the air transversely glides over the surfaces of the fan blades and is delivered forwards. In the process, as the air flows through the comb needles on the surfaces of the fan blades, the blocky air is combed and divided by the comb needles into fine fragments. The gentle-breeze fan blade is capable of forming the air sent out by the fan into gentle and soft breeze so that a user can feel more comfortable.
Description
The present invention is application number is 201210267919.8, and the applying date is on 07 31st, 2012, and denomination of invention is the divisional application of the application for a patent for invention of " gentle breeze flabellum ".
Technical field
The present invention relates to technical field of mechanical equipment, especially, relate to the flabellum on a kind of household fan.
Background technique
Electric fan is a kind of conventional household electric appliance, principal organ comprises a drive motor and a flabellum. wherein, flabellum generally at least comprises three blades, arrange in skewed wound motor axle. when electric machine rotation, flabellum promotes air by its surface tilted, make its laterally slip over blade surface backward before send.But promote in air event at flabellum, air is pushed out along flabellum cambered surface with becoming block, under high-revolving state, air block hardness is comparatively large, blows and have strong pulse sense on human body, its ductility and comfort level poor.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of gentle breeze flabellum of household fan, the continuous soft temperature of the wind that this kind of gentle breeze flabellum can make electric fan send is soft, makes user more comfortable.
The technical solution adopted for the present invention to solve the technical problems is: this gentle breeze flabellum comprises more than the three arc flabellums be evenly distributed on panoramatic head.The forward surface of described flabellum is covered with card wire.
As preferably, described card wire is the sharp-pointed metal needle in top.This kind of card wire can when electric fan be blown towards east-west direction, the cutting earth magnetism magnetic line of force, thus make card wire two ends produce certain potential difference, make the needle point of card wire assembles a small amount of electric charge, to the micronic dust in air and harmful large molecule, there is absorption and ionization decomposition.When blowing towards North and South direction to make electric fan, also have this kind of effect, further, described flabellum is made up of nonconductor, a wires is drawn in the end that each described metallic card wire contacts with flabellum, and this wire extends to described panoramatic head.The wire that all described card wires are drawn converges to a metal body on described convolution seat, this metal body ground connection.Now, when electric fan is blown towards North and South direction, cut terrestrial magnetic field by each described wire, and make the most advanced and sophisticated static electricity gathered lotus of described card wire thus.
Beneficial effect of the present invention is: this gentle breeze flabellum operationally, flabellum promotes in air event, air laterally slips over blade surface, then sent forward, because air will flow through the card wire of blade surface in this process, therefore, the air of original bulk will be split by card wire combing, form tiny fragment group, become continuous soft temperature thus soft, make user feel more comfortable pleasant.
Accompanying drawing explanation
Fig. 1 is the front view of an embodiment of this gentle breeze flabellum.
Fig. 2 is the side view of Fig. 1 embodiment.
Reference character in above-mentioned accompanying drawing is as follows: arc flabellum 1, panoramatic head 2, card wire 10.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
In Fig. 1, Fig. 2 illustrated embodiment, the gentle breeze flabellum of this household fan comprises more than the three arc flabellums 1 be evenly distributed on panoramatic head 2.The forward surface of described flabellum 1 is covered with card wire 10.
Described card wire 10 is the sharp-pointed metal needle in top.This kind of card wire 10 is when electric fan is blown towards east-west direction, and because the terrestrial magnetic field magnetic line of force is along North and South direction, therefore card wire 10 will cut the earth magnetism magnetic line of force.According to electromagnetic induction principle, card wire 10 two ends, by producing certain potential difference, make the needle point of card wire 10 assembles a small amount of electric charge, have absorption and ionization decomposition to the micronic dust in air and harmful large molecule.And when blowing towards North and South direction to make electric fan, also there is this kind of effect, further, described flabellum 1 being made up of nonconductor.A wires (not shown) is drawn in the end that each described metallic card wire 10 contacts with flabellum 1.This wire radially extends to described panoramatic head 2 along flabellum 1 surface relative to described panoramatic head 2.The wire that all described card wires 10 are drawn converges to a metal body on described convolution seat 2, this metal body ground connection.Thus, described wire and card wire 10 are roughly in orthogonal position relationship.Therefore, when electric fan is blown towards North and South direction, will terrestrial magnetic field be cut by each described wire, and make the most advanced and sophisticated static electricity gathered lotus of described card wire 10 thus.
Operationally, flabellum 1 promotes in air event above-mentioned gentle breeze flabellum, and air laterally slips over flabellum 1 surface, is then sent forward.Because air will flow through the card wire 10 of blade surface, as shown in arrow line in Fig. 1 in this process.Therefore, original block air will be split by card wire 10 combing, form tiny fragment group, will become continuous soft temperature thus soft, make user feel more comfortable pleasant.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
